  When performing maintenance or the like of the lighting device incorporated in the fence, removal work and mounting work of the lighting device occur. For example, when a conventional technique such as Patent Document 1 is used, workability is improved to some extent. However, there is a limit to improvement in workability because work on a member that covers the lighting device occurs.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a ballast, a fence, a repair unit, and a repair method that can improve workability in the work of removing and attaching a lighting device. And

  In order to achieve the above object, a ballast according to the present invention includes a ballast body that can be fixed to a transverse member of a fence, and the ballast body has a longitudinal direction with respect to a vertical plane along the direction in which the ballast bodies are arranged. A fixing part for fixing an auxiliary body for lighting attachment capable of incorporating a lighting device so as to irradiate light to at least one of them is provided. When the lighting device needs to be maintained in the fence, the lighting attachment auxiliary body can be detached from the ballast body together with the lighting device. For this reason, the ballast can improve workability in the work of removing and attaching the lighting device.

  As a desirable mode of the present invention, it is preferable that the fixing portion has a hole to which a fixing member for fixing the auxiliary body for lighting attachment is fixed. This facilitates fixing of the lighting attachment auxiliary body to the ballast body.

  As a desirable aspect of the present invention, it is preferable that the fixing portion includes a protrusion sandwiched from both sides by the lighting attachment auxiliary body. Thereby, the play of the auxiliary body for lighting attachment is suppressed.

  As a desirable aspect of the present invention, it is preferable that the fixing portion includes a positioning portion for restricting a position of the lighting attachment auxiliary body in the front-rear direction. This facilitates positioning of the lighting attachment auxiliary body when the lighting attachment auxiliary body is attached to the ballast body.

  As a desirable aspect of the present invention, the illumination mounting auxiliary body is fixed to the ballast body by engaging a convex portion provided on the illumination mounting auxiliary body and a concave portion provided on the ballast body. It is preferable. Thereby, since the member for fixing the auxiliary body for illumination attachment to a ballast main body is unnecessary for a ballaster, workability | operativity when the auxiliary body for illumination attachment is attached to a ballast main body can be improved. .

  As a desirable aspect of the present invention, it is preferable that a lighting device storage case that can be stored inside the lighting attachment auxiliary body is provided, and the lighting device is mounted on the lighting device storage case. Thereby, possibility that a lighting device will be damaged is reduced.

  As a desirable mode of the present invention, it is preferable to include a positioning member for regulating the position of the lighting device storage case in the front-rear direction. Thereby, the rattling of the lighting device storage case is suppressed.

  As a desirable mode of the present invention, it is preferable that the lighting device is attached to the auxiliary body for lighting attachment. Thereby, since the number of parts is reduced as compared with the case where the lighting device storage case is provided, the assembly of the ballast is facilitated.

  As a desirable mode of the present invention, it is preferable that the lighting attachment auxiliary member is a light shielding member and regulates the direction of light emitted by the lighting device. Thereby, the ballast can control the direction in which the light travels in a preferable direction according to the traveling direction of the pedestrian or driver.

  As a desirable mode of the present invention, it is preferable that a translucent cover is provided at a front end portion in the front-rear direction of the lighting attachment auxiliary body. Thereby, light is irradiated toward the front-back direction from a ballast. For this reason, since the light which goes to a pedestrian or a driver is reduced, possibility that a pedestrian or a driver will feel dazzling is reduced.

  As a desirable mode of the present invention, the fence is provided with a plurality of support columns arranged in one direction, a first horizontal member supported by the support columns, and supported by the support columns and below the first horizontal member. A second lateral member, and a plurality of ballasts supported by the first lateral member and the second lateral member, wherein at least one of the plurality of ballasts includes the first lateral member and the second lateral member. A ballast body fixed to a horizontal member and a lighting device can be built in so as to irradiate light in at least one of the front and rear directions with respect to the vertical plane along the direction in which the ballast bodies are arranged. It is preferable to provide an auxiliary body for lighting attachment. Thereby, when maintenance of an illuminating device becomes necessary in a fence, it is possible to remove the auxiliary body for lighting attachment from the ballast body together with the illuminating device. For this reason, the fence can improve workability | operativity in the removal operation | work of an illuminating device, and an attachment operation | work.

  As a desirable mode of the present invention, it is preferable that electric power is supplied to a power supply device included in the lighting device via a wiring passed through the first horizontal member or the second horizontal member. Thereby, since the number of wiring visible from the outside is reduced, the design of the fence is improved.

  As a desirable mode of the present invention, it is preferable that the power supply device is disposed inside the auxiliary body for attaching light. Thereby, since it becomes easy to produce a space inside the 1st horizontal member or the 2nd horizontal member, construction of wiring becomes easy.

  As a desirable aspect of the present invention, in a ballast corresponding to a position where light does not need to be irradiated among a plurality of the ballasts, a fixing portion for fixing the illumination mounting auxiliary body of the ballast body is exposed. It is preferable. When it is not necessary for all the ballasts to irradiate light, the above-described ballasters are used, so that the interval between the ballasts is maintained and the illuminance on the road surface can be easily adjusted. Moreover, the auxiliary body for illumination attachment is easily attached to a ballast as needed.

  As a desirable mode of the present invention, a dummy member supported by the first transverse member and the second transverse member is provided at a position where it is not necessary to irradiate light, and the dummy member is a plane perpendicular to the longitudinal direction. It is preferable that the cut cross-sectional shape is the same as the cross-sectional shape obtained by cutting the ballast having the ballast body and the lighting attachment auxiliary body along a plane perpendicular to the longitudinal direction. When all the ballasts do not have to irradiate light, the dummy member is used, so that the interval between the ballasts is maintained and the illuminance on the road surface can be easily adjusted. Further, the appearance of the dummy member is similar to that of the ballast. For this reason, even when ballast and dummy members are mixed in the fence, the design of the fence is improved.

  As a desirable mode of the present invention, it is preferably provided on a staircase. Thereby, since a fence can irradiate light to the road surface of a staircase, it can improve the safety | security with respect to the pedestrian of a staircase.

  As a desirable mode of the present invention, it is preferable that the ballast having the ballast body and the lighting attachment auxiliary body is disposed at a position corresponding to an ascending / descending entrance or landing for the stairs. Thereby, since light is irradiated to the road surface of the place where a slope changes a fence, the safety | security with respect to the pedestrian of a staircase can be improved.

  As a desirable mode of the present invention, the fence is a fence modified from the existing fence, and the existing ballast is irradiated with light in at least one of the front and rear directions with respect to the vertical plane along the direction in which the ballasts are arranged. It is preferable that a lighting unit capable of incorporating a lighting device is attached to the. Thereby, when maintenance of an illuminating device is needed in a fence, it is possible to remove an illuminating unit from a ballaster integrally with an illuminating device. For this reason, the fence can improve workability | operativity in the removal operation | work of an illuminating device, and an attachment operation | work. A streetlight with a lighting fixture attached to the tip of the pole may be installed around the fence of the pedestrian bridge that has been provided. If the fence of the pedestrian bridge provided conventionally becomes the above-mentioned fence, since a streetlight becomes unnecessary, a streetlight can be removed. For this reason, the fence mentioned above contributes to the reduction of the maintenance work of the streetlight used as the work in a high place. Moreover, since the light which goes under a footbridge is suppressed compared with the case where a streetlight is installed, possibility that the driver of the vehicle which passes along the road which passes under a footbridge will feel dazzling is reduced.

  As a desirable mode of the present invention, the refurbishment unit is a refurbishment unit that is attached to an existing ballast, and includes a first sandwiching part and a second sandwiching part that sandwich the ballast from both sides, and the second sandwiching part from the first sandwiching part.

It is preferable to provide an illumination unit that can incorporate the illumination device. Thereby, when maintenance of an illuminating device is needed in a fence, it is possible to remove an illuminating unit from a ballaster integrally with an illuminating device. For this reason, a repair unit can improve workability | operativity in the removal operation | work and attachment operation | work of an illuminating device.

  As a desirable mode of the present invention, the first sandwiching portion includes a fastening member that protrudes from a surface facing the ballast and contacts the ballast, and the adapter is between the fastening member and the ballast and the It is preferable that the ballast is fixed to the ballast by friction generated between the second sandwiching portion and the ballast. This eliminates the need for processing such as making a hole in the ballast, thus improving the workability when the repair unit is attached to the ballast.

  As a desirable mode of the present invention, the repair method is a repair method of an existing fence, and the existing ballast is irradiated with light in at least one of the front and rear directions with respect to the vertical plane along the direction in which the ballasts are arranged. It is preferable to include the process of attaching the illumination unit which can incorporate an illuminating device. When maintenance of the lighting device is necessary in the fence renovated by this repair method, the lighting unit can be removed from the ballast together with the lighting device.

  Embodiments for carrying out the present invention will be described in detail with reference to the drawings. The present invention is not limited by the contents described in the following embodiments. The constituent elements described below include those that can be easily assumed by those skilled in the art and those that are substantially the same. Furthermore, the constituent elements described below can be appropriately combined. Some components may not be used.

(Embodiment 1)
FIG. 1 is a front view illustrating a fence according to the first embodiment. FIG. 2 is a plan view showing the fence according to the first embodiment. 3 is a cross-sectional view taken along the line AA in FIG. 4 is a cross-sectional view taken along the line BB in FIG. 5 is a cross-sectional view taken along the line CC in FIG. 6 is a cross-sectional view taken along the line DD in FIG. The fence 1 which concerns on Embodiment 1 is a handrail provided in the channel | path 100 through which a pedestrian passes, for example. The fence 1 may be a handrail provided on a road through which the vehicle passes. Moreover, a fence is a general term including a railing, a guard fence for vehicles, a handrail, a sidewalk fence, a fence, and the like, and is used in the same meaning in the following.

  As shown in FIGS. 1 to 3, the fence 1 is provided on a ground cover 200 provided at an edge of the passage 100. The ground cover 200 is provided along the edge of the passage 100 and protrudes upward from the road surface of the passage 100. For example, the ground cover 200 is made of concrete and is about 100 mm higher than the road surface of the passage 100.

  The fence 1 includes a support column 10, a first lateral member 11, a second lateral member 12, and a ballast 2. A plurality of support columns 10 are provided along the edge of the passage 100, and each column 10 is fixed to the ground cover 200 via a pedestal 101. The plurality of support columns 10 are arranged at a predetermined interval from each other. The support column 10 is made of, for example, a structural aluminum alloy.

  The first transverse member 11 is a long member extending in the horizontal direction and spanned between adjacent struts 10. As shown in FIG. 5, the first lateral member 11 includes an outer member 111 and an inner member 112. The outer member 111 is a substantially U-shaped extruded shape member formed of, for example, a structural aluminum alloy. The outer member 111 is fixed to the column 10 by a fastening member such as a bolt. The inner member 112 is a substantially I-shaped extruded shape member made of, for example, a structural aluminum alloy. The inner member 112 is disposed inside the outer member 111 and is supported by the outer member 111. More specifically, two protrusions are provided on the inner wall of the outer member 111, and grooves provided at both ends of the inner member 112 are hooked on the protrusions of the outer member 111.

  The second transverse member 12 is a long member extending in the horizontal direction and spanned between adjacent struts 10. The second transverse member 12 is disposed below the first transverse member 11 and is fixed to the column 10 by a fastening member such as a bolt. The second transverse member 12 is made of, for example, a structural aluminum alloy. As shown in FIG. 6, the second lateral member 12 is, for example, a substantially U-shaped extruded shape member.

  The ballast 2 is a long member that is supported by the first transverse member 11 and the second transverse member 12 and that is long in the vertical direction. More specifically, one end of the ballast 2 is connected to the inner member 112 of the first lateral member 11 and the other end of the ballast 2 is connected to the second lateral member 12. A plurality of ballasters 2 are provided along the direction in which the columns 10 are arranged. The plurality of ballasters 2 are arranged at a predetermined interval from each other. In the following description, the orthogonal direction to the vertical plane 1000 (see FIGS. 2 and 3) along the direction in which the ballasts 2 are arranged is described as the front-rear direction. The direction in which the passage 100 is seen from the fence 1 is described as a front Df, and the direction opposite to the passage 100 as viewed from the fence 1 is described as a rear Db. For example, in FIG. 2, the lower side is the front Df and the upper side is the rear Db. For example, in FIG. 3, the right side is the front Df and the left side is the rear Db. Further, a horizontal direction and a direction orthogonal to the front-rear direction is described as a left-right direction. That is, the direction in which the ballasts 2 are arranged is the left-right direction.

  As shown in FIG. 4, the ballast 2 includes a ballast body 21, a lighting attachment auxiliary body 22, a lighting device storage case 23, a translucent cover 24, and a buffer member 25.

  The ballast main body 21 is a member for ensuring the strength required for the ballast 2, and supports the lighting attachment auxiliary body 22. For example, it is made of a structural aluminum alloy or the like. The ballast body 21 is, for example, a cylindrical extruded shape, and includes two screw holes 212 and a screw hole 213 inside. The two screw holes 212 and the screw holes 213 are arranged in the front-rear direction. As shown in FIG. 5, the ballast body 21 is connected to the inner member 112 by inserting a screw 28 penetrating the inner member 112 of the first lateral member 11 into the screw hole 212 and the screw hole 213. As shown in FIG. 6, the ballast body 21 is connected to the second lateral member 12 by inserting a screw 29 penetrating the second lateral member 12 into the screw hole 212 and the screw hole 213.

  As shown in FIG. 4, the ballast body 21 includes a base 218 and a fixing part 210. The base 218 is disposed at the rear Db end of the ballast body 21. For example, the cross-sectional shape of the base 218 is substantially U-shaped, and the width in the left-right direction of the base 218 increases toward the front Df. For example, the fixing portion 210 is provided integrally with the base portion 218 on the front side Df of the base portion 218. The fixing unit 210 includes a protrusion 219, a hole 211, and a positioning unit 214.

  The protrusion 219 protrudes from the end of the front Df of the base 218 toward the front Df. For example, the cross-sectional shape of the protrusion 219 is a substantially U shape opposite to the substantially U shape of the base 218. More specifically, the protrusion 219 includes two side surfaces orthogonal to the left-right direction and an end surface orthogonal to the front-rear direction and connecting the two side surfaces. The hole 211 is provided on the side surface of the protrusion 219. For example, the width in the left-right direction of the protrusion 219 is constant and is smaller than the width in the left-right direction at the end of the front Df of the base 218. As a result, a step is generated between the base 218 and the protrusion 219. For this reason, the positioning part 214 is formed in the edge part of the front Df of the base part 218 as an end surface orthogonal to the front-back direction. In other words, the member on the rear Db side of the positioning unit 214 in the ballast body 21 is the base 218, and the member on the front Df side of the positioning unit 214 in the ballast body 21 is the protrusion 219.

  The lighting attachment auxiliary body 22 is a housing in which the lighting device 3 can be built, and is attached to the ballast body 21. That is, the lighting attachment auxiliary body 22 is a member for attaching the lighting device 3 to the ballast body 21. The lighting attachment auxiliary body 22 is a substantially H-shaped extruded shape member made of, for example, a structural aluminum alloy. The lighting attachment auxiliary body 22 is a member that does not transmit light, that is, a light blocking member. The lighting attachment auxiliary body 22 includes a base portion 220, a clamping portion 221, and a claw portion 223. The base 220 is disposed on the front Df of the end surface of the protrusion 219 of the ballast body 21. For example, the cross-sectional shape of the base 220 is a substantially U-shape that opens toward the front Df. The width of the base 220 in the left-right direction is smaller toward the front Df. Two sandwiching portions 221 are provided. Each of the two sandwiching portions 221 protrudes toward the rear Db from both ends in the left-right direction at the end of the rear Db of the base 220. The sandwiching portion 221 is in contact with the side surface of the protrusion 219. That is, the pair of sandwiching portions 221 sandwiches the protrusion 219 from both sides. The thickness of the clamping part 221 in the left-right direction is equal to the size of the step between the base part 218 and the protrusion 219 in the ballast body 21. Thereby, a level | step difference is hard to arise between the ballast main body 21 and the clamping part 221. FIG. Further, the length in the front-rear direction of the sandwiching portion 221 is equal to the length in the front-rear direction of the protrusion 219 of the ballast body 21. Thereby, the tip of the clamping part 221 is in contact with the positioning part 214 of the ballast body 21. The positioning unit 214 regulates the position of the lighting attachment auxiliary body 22 in the front-rear direction. In addition, a hole 222 is provided in the sandwiching portion 221. The hole 222 is disposed so as to overlap with the hole 211 provided in the protrusion 219. The fixing member 26 is fixed to the hole 211 and the hole 222. The fixing member 26 is, for example, a bolt, and more specifically, an ultra-low head bolt. As a result, the lighting attachment auxiliary body 22 is connected to the ballast body 21. The claw portion 223 protrudes inward in the left-right direction at the end portion of the front portion Df of the base portion 220.

  The lighting device storage case 23 is a member for facilitating the work of placing the lighting device 3 inside the lighting attachment auxiliary body 22 and protecting the lighting device 3. The lighting device storage case 23 is made of, for example, a synthetic resin. The cross-sectional shape of the lighting device storage case 23 is a substantially U-shape that opens toward the front Df. The lighting device storage case 23 is disposed inside the base portion 220 of the lighting attachment auxiliary body 22. A light emitting unit 31 of the lighting device 3 to be described later is attached to the bottom surface of the lighting device storage case 23. In addition, a positioning member 27 is provided at a position of the base 220 that faces the bottom surface of the lighting device storage case 23. The positioning member 27 is, for example, a hexagon socket set screw, and is attached to a female screw 224 provided on the base 220. The positioning member 27 protrudes from the female screw 224 to the front Df, and pushes the lighting device storage case 23 toward the front Df. Accordingly, the lighting device storage case 23 is positioned by being sandwiched between the claw portion 223 and the positioning member 27 via the translucent cover 24 and the buffer member 25. Since the positioning member 27 pushes the lighting device storage case 23, rattling of the lighting device storage case 23 is suppressed. The hexagon socket head set screw is also referred to as a female screw.

  The translucent cover 24 is a member that transmits light from the light emitting unit 31 in a predetermined direction. The translucent cover 24 is a plate-like member made of, for example, polycarbonate. The translucent cover 24 is disposed at the end portion of the front Df of the lighting attachment auxiliary body 22 and covers the opening portion of the lighting device storage case 23. The translucent cover 24 is disposed in parallel with the vertical surface 1000 and faces the light emitting unit 31 provided on the bottom surface of the lighting device storage case 23. The translucent cover 24 is fixed to the lighting attachment auxiliary body 22 by being pressed against the claw portion 223 by the lighting device storage case 23.

  The buffer member 25 is made of, for example, a synthetic resin. The buffer member 25 is disposed between the translucent cover 24 and the claw portion 223. The buffer member 25 is deformed according to the magnitude of the applied force, thereby filling the space between the translucent cover 24 and the claw portion 223.

  Note that the fixing member 26 is not necessarily a bolt, and may be, for example, a rivet. Further, the positioning member 27 is not necessarily a hexagon socket set screw, and may be a flat head screw, for example. Moreover, the translucent cover 24 does not necessarily need to be a polycarbonate, for example, an acrylic etc. may be sufficient as it. Further, the buffer member 25 does not necessarily need to be a synthetic resin, and may be, for example, a synthetic rubber. Further, the buffer member 25 may be omitted.

  FIG. 7 is a plan view showing the lighting apparatus according to the first embodiment. As illustrated in FIG. 7, the lighting device 3 includes a light emitting unit 31, a wiring 32, a power supply device 33, and a wiring 34.

  The light emitting unit 31 includes a base 310 and a plurality of light emitting elements 311. The base 310 is a flexible member formed of, for example, silicone rubber. For example, the base 310 is formed in a tape shape having a thickness of about 3 mm. The base 310 is attached to the lighting device storage case 23 shown in FIG. 4 with, for example, an adhesive. The light emitting element 311 is, for example, a light emitting diode, that is, an LED (Light Emitting Diode). As shown in FIG. 7, the plurality of light emitting elements 311 are arranged at equal intervals along the longitudinal direction of the substrate 310.

  The power supply device 33 is a device that converts AC power into DC power, and is a so-called AC-DC adapter. The power supply device 33 is electrically connected to the light emitting unit 31 by the wiring 32. The power supply device 33 can supply DC power to the light emitting element 311 via the wiring 32. In addition, the power supply device 33 is provided with a wiring 34 at a position opposite to the wiring 32.

  As shown in FIG. 5, the lighting device 3 is housed inside a lighting attachment auxiliary body 22. For example, in the first embodiment, the power supply device 33 is disposed at the upper end portion of the lighting attachment auxiliary body 22, and the wiring 32 and the light emitting portion 31 are provided downward from the lower end portion of the power supply device 33. The wiring 34 is connected to the wiring 41 via a connector 35 such as a plug. The wiring 41 is connected to the wiring 40 disposed inside the first lateral member 11 through a wiring hole 113 provided in the inner member 112. The wiring 40 is connected to a power line in the vicinity of the fence 1. As a result, AC power is supplied to the power supply device 33 via the wiring 40, the wiring 41, and the wiring 34.

  When DC power is supplied from the power supply device 33 to the light emitting unit 31, the light emitting element 311 emits light. Since the illumination attachment auxiliary member 22 is a light shielding member, the direction of the light emitted by the light emitting element 311 is restricted by blocking a part of the light emitted by the light emitting element 311. A part of the light emitted from the light emitting element 311 is transmitted toward the front Df through the translucent cover 24 disposed to face the light emitting unit 31. In other words, in the ballast 2, light is irradiated toward the front Df by the lighting device 3 built in the lighting attachment auxiliary body 22. Then, the light traveling toward the front Df of the ballast 2 irradiates the road surface of the passage 100. Thus, the illumination attachment auxiliary body 22 can incorporate the illumination device 3 so as to irradiate the front Df with light.

  In the fence 1, when the lighting device 3 needs to be maintained, the lighting attachment auxiliary body 22 is removed from the ballast body 21. Specifically, the lighting attachment auxiliary body 22 can be detached from the ballast body 21 by removing the fixing member 26. When a part of the lighting attachment auxiliary body 22 is detached from the ballast body 21, the wiring 34, the connector 35, and the wiring 41 are exposed. For this reason, it is easy to release the connection between the wiring 34 and the wiring 34 by the connector 35. If the connection of the wiring 34 and the wiring 34 is cancelled | released, the auxiliary body 22 for lighting attachment and the illuminating device 3 can leave | separate from the fence 1 with it being integral. Then, the maintenance is completed by attaching the lighting attachment auxiliary body 22 incorporating the new lighting device 3 or the repaired lighting device 3 to the ballast body 21. More specifically, after the wiring 34 of the new lighting device 3 or the repaired lighting device 3 is connected to the wiring 41, the lighting attachment auxiliary body 22 is attached to the ballast body 21 by the fixing member 26.

  Thus, when the maintenance of the illuminating device 3 becomes necessary in the fence 1, it is possible to remove the lighting attachment auxiliary body 22 from the ballast body 21 integrally with the illuminating device 3. For this reason, the ballast 2 can improve workability in the work of removing and attaching the lighting device.

The ballast 2A is different from the ballast 2 described above in that the ballast 2A is not provided with the lighting attachment auxiliary body 22. As shown in FIG. 8, in the ballast 2A, the fixing portion 210 is exposed. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As described above, the road surface of the passage 100 is irradiated with the light emitted from the lighting device 3. For example, the illuminance on the road surface is preferably 20 lux or more at a position of 2 m from the fence 1. On the other hand, if the illuminance on the road surface is too large, the pedestrian or driver may feel dazzling. For this reason, all the ballasters 2 may not have to irradiate light. In such a case, by arranging the ballast 2 corresponding to the position where it is not necessary to irradiate light among the plurality of ballasts 2 as the ballast 2A according to the first modification, the interval between the ballasts 2 is maintained. In addition, the road surface illumination can be easily adjusted. Moreover, the auxiliary body 22 for illumination attachment is easily attached to the ballast 2A as needed.

The spacing between the stars 2 is maintained, and the illuminance on the road surface can be easily adjusted. However, in the state where the ballast 2 and the ballast 2A having different appearances are mixed, the design of the fence 1 may be difficult to improve.

  On the other hand, the cross-sectional shape obtained by cutting the dummy member 2B along a plane perpendicular to the longitudinal direction is the same as the cross-sectional shape obtained by cutting the ballast 2 described above along a plane perpendicular to the longitudinal direction. Thereby, the external appearance of the dummy member 2B is similar to the external appearance of the ballast 2. For this reason, even when the ballast 2 and the dummy member 2B are mixed in the fence 1, the design of the fence 1 is improved.

(Modification 3)
FIG. 10 is a cross-sectional view showing a ballast according to the third modification. A ballast 2C according to Modification 3 includes a ballast body 21C and a lighting attachment auxiliary body 22C. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  The ballast body 21C includes a fixing portion 210C different from the fixing portion 210 according to the first embodiment. The protrusion 219C in the fixing portion 210C includes a concave portion 215 on a side surface (a surface orthogonal to the left-right direction).

And when the convex part 225 reaches the position of the recessed part 215, the deformation | transformation of the clamping part 221C will restore | restore, and the convex part 225 will mesh with the recessed part 215. FIG. Thereby, the auxiliary body for lighting attachment 22C is fixed to the ballast main body 21C. Such an attachment method may be referred to as a mechanical clamp method.

  In the ballast 2C according to the third modification, a separate member for fixing the lighting attachment auxiliary body 22C to the ballast main body 21C is unnecessary. For this reason, ballast 2C concerning modification 3 can make attachment of auxiliary body 22C for illumination attachment to ballast main part 21C easy. That is, the ballast 2C can improve the workability when the lighting attachment auxiliary body 22C is attached to the ballast main body 21C.

  In the ballast 2D, the light emitting part 31 of the lighting device 3 is directly attached to the auxiliary body for lighting attachment 22D. Specifically, the light emitting unit 31 is attached to the bottom surface of the base 220 with an adhesive.

  Since the ballast 2D does not include the lighting device storage case 23 as compared with the first embodiment described above, the number of parts can be reduced. For this reason, the ballast 2D can be easily assembled.

  The ballast 2D is preferably used when the lighting device 3 can be fixed to the lighting attachment auxiliary body 22D in advance in a factory or the like. In the above-described ballast 2 according to the first embodiment, the lighting device 3 may be attached to the lighting attachment auxiliary body 22 in advance in a factory or the like, or the lighting device 3 is attached to the lighting attachment auxiliary body 22 at the site.

On the other hand, in the ballast 2D, after the lighting device 3 is fixed to the lighting attachment auxiliary body 22D, it is necessary to fix the translucent cover 24D to the lighting attachment auxiliary body 22D using an adhesive or the like. For this reason, it is preferable to assemble the lighting attachment auxiliary body 22D in a factory or the like.

(Modification 5)
FIG. 12 is a cross-sectional view showing a ballast according to the fifth modification. The ballast 2E according to Modification 5 is different from the ballast 2 according to Embodiment 1 described above in that the lighting device storage case 23 is not provided. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

The translucent cover 24 </ b> E includes a plate portion 240 formed in a plate shape, and two cover-side claw portions 241 that protrude from the plate portion 240 to the rear Db. The plate part 240 is in contact with the surface on the front Df side of the claw part 223E. The cover side claw portion 241 is engaged with the claw portion 223E.

  In the ballast 2E according to the modified example 5, when the translucent cover 24E is attached to the lighting attachment auxiliary body 22E, the cover side claw portion 241 is pushed between the pair of claw portions 223E. When the cover-side claw portion 241 contacts the claw portion 223E, the cover-side claw portion 241 is deformed in the left-right direction. Then, when the cover-side claw 241 gets over the claw 223E, the deformation of the claw 223E is restored, so that the cover-side claw 241 is engaged with the claw 223E. Thereby, the translucent cover 24E is fixed to the lighting attachment auxiliary body 22E. Such an attachment method may be referred to as a mechanical clamp method.

  In the ballast 2E, the light emitting part 31 of the lighting device 3 is directly attached to the auxiliary body 22E for lighting attachment. Specifically, the light emitting unit 31 is attached to the bottom surface of the base 220 with an adhesive.

  Since the ballast 2E does not include the lighting device storage case 23 as compared with the first embodiment described above, the number of parts can be reduced. For this reason, the ballast 2E can be easily assembled.

  Further, in the ballast 2E according to the modified example 5, an adhesive for fixing the translucent cover 24E to the lighting attachment auxiliary body 22E is unnecessary. For this reason, ballast 2E concerning modification 5 can make easy attachment of translucent cover 24E to auxiliary body 22E for illumination attachment. That is, the ballast 2E can improve the workability when the translucent cover 24E is attached to the illumination attachment auxiliary body 22E.

  Furthermore, since the process of using the adhesive is eliminated, the work of fixing the translucent cover 24E to the lighting attachment auxiliary body 22E is facilitated even in the field. For this reason, in the ballast 2E according to the modified example 5, the lighting device 3 may be attached to the lighting attachment auxiliary body 22E in advance in a factory or the like, or the lighting device 3 is attached to the lighting attachment auxiliary body 22E in the field.

(Modification 6)
FIG. 13 is a cross-sectional view showing a ballast according to the sixth modification. FIG. 14 is a cross-sectional view showing a ballast according to the sixth modification. The direction of the light which the illuminating device 3 emits differs in the ballast 2F which concerns on the modification 6 compared with the ballast 2 which concerns on Embodiment 1 mentioned above. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As illustrated in FIG. 13, the lighting attachment auxiliary body 22 </ b> F includes a base portion 220 </ b> F, a sandwiching portion 221, a claw portion 226, and a claw portion 227. The cross-sectional shape of the base 220F is a substantially L shape having one side facing the protrusion 219 and the other side protruding from one end of the one side to the front Df. The claw portion 226 protrudes inward in the left-right direction at the end portion of the front portion Df of the base portion 220F. The claw portion 227 protrudes toward the front Df at the end portion in the left-right direction of the base portion 220F. More specifically, the nail | claw part 226 is arrange | positioned from the front-end | tip part of the base 220F in the position close | similar to the back Db side by the thickness of the translucent cover 24F. The nail | claw part 227 is arrange | positioned from the front-end | tip part of the base 220F in the position close | similar to the inner side of the left-right direction by the thickness of the translucent cover 24F.

  The translucent cover 24F is, for example, a plate-like member that is partially bent. The translucent cover 24F is fixed to the front Df side surface of the claw portion 226 and the left and right outer surface of the claw portion 227 with an adhesive, for example. Moreover, in the ballast 2F, the light emission part 31 of the illuminating device 3 is directly attached to the auxiliary body 22F for illumination attachment.

  A part of the light emitted by the light emitting element 311 is transmitted through the translucent cover 24F disposed in one of the front Df and the left-right direction of the light emitting unit 31 toward the front Df and one of the left-right direction. That is, in the ballast 2F, light is irradiated toward the front Df and one of the left and right directions by the lighting device 3 built in the lighting attachment auxiliary body 22F. And the light which goes to the front Df of the ballast 2F and one of the left-right direction irradiates the road surface of the channel | path 100. FIG. In this way, the illumination attachment auxiliary body 22F can incorporate the illumination device 3 so as to irradiate light in one of the front Df and the left-right direction.

  In the ballast 2F, light is emitted to the front Df and one of the left and right directions, so that the area that can be illuminated is larger than that of the ballast 2 of the first embodiment. For this reason, in the fence 1 using the ballast 2F, it is possible to reduce the number of ballasts 2F necessary for setting the illuminance on the road surface of the passage 100 to a predetermined value or more. Therefore, the ballast 2F can suppress power consumption for setting the illuminance on the road surface of the passage 100 to a predetermined value or more.

  Moreover, when the advancing direction of the pedestrian in the channel | path 100 is constant, it is preferable that the direction of the light which the ballast 2F emits is the same direction as the advancing direction of a pedestrian among the front Df and the left-right direction. That is, it is preferable that the translucent cover 24 </ b> F is disposed so as to cover the front Df with respect to the light emitting unit 31 and the same direction as the pedestrian travel direction with respect to the light emitting unit 31. In other words, the ballast 2F shown in FIG. 13 is preferably used when the pedestrian travels from the left side to the right side in FIG. If light is emitted in a direction opposite to the direction of travel of the pedestrian, the light may easily enter the eyes of the pedestrian, so the pedestrian may feel dazzling. On the other hand, since the ballast 2F suppresses the light from entering the eyes of the pedestrian, the possibility that the pedestrian feels dazzling can be reduced.

  When the passage 100 is a road through which a vehicle passes, the direction of light emitted by the ballast 2F may be the same as the traveling direction of the vehicle among the front Df and the left-right direction. Further, as shown in FIG. 14, by reversing the position of the lighting attachment auxiliary body 22 </ b> F and the position of the translucent cover 24 </ b> F, the ballast 2 </ b> F has a passage 100 in which the traveling direction of the pedestrian or vehicle is reversed. It can also be applied to.

(Modification 7)
FIG. 15 is a cross-sectional view showing a ballast according to Modification 7. The direction of the light which the illuminating device 3 emits differs in the ballast 2G which concerns on the modification 7 compared with the ballast 2 which concerns on Embodiment 1 mentioned above. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As illustrated in FIG. 15, the lighting attachment auxiliary body 22G includes a base portion 220G, a clamping portion 221, a claw portion 226G, and a claw portion 227G. The cross-sectional shape of the base 220G is a substantially L shape having one side facing the protrusion 219 and the other side protruding from one end of the one side to the front Df. The claw portion 226G protrudes inward in the left-right direction at the end portion of the front portion Df of the base portion 220G and has a plurality of bent portions. The claw portion 227G protrudes toward the front Df at the left and right end portions of the base portion 220G and has a bent portion. More specifically, the claw portion 226G is bent in a substantially S shape. The claw portion 227G is bent in a substantially L shape.

  The translucent cover 24G is, for example, a plate member that is partially bent. The translucent cover 24 </ b> G includes a cover side claw portion 242, a cover side claw portion 243, a cover side claw portion 244, and a cover side claw portion 245. The cover side claw portion 242 and the cover side claw portion 243 mesh with the claw portion 226G. The cover-side claw portion 244 and the cover-side claw portion 245 are engaged with the claw portion 227G.

  In the ballast 2G according to the modified example 7, when the translucent cover 24G is attached to the illumination attachment auxiliary body 22G, the translucent cover 24G is pushed between the claw portion 226G and the claw portion 227G in a deformed state. . The cover side claw portion 242 and the cover side claw portion 243 mesh with the claw portion 226G, and the cover side claw portion 244 and the cover side claw portion 245 mesh with the claw portion 227G. Thereby, the translucent cover 24G is fixed to the auxiliary body 22G for lighting attachment. Such an attachment method may be referred to as a mechanical clamp method.

  Further, in the ballast 2G according to the modified example 7, an adhesive for fixing the translucent cover 24G to the lighting attachment auxiliary body 22G is unnecessary. For this reason, the ballast 2G according to the modified example 7 can facilitate attachment of the translucent cover 24G to the illumination attachment auxiliary body 22G. That is, the ballast 2G can improve workability when the translucent cover 24G is attached to the illumination attachment auxiliary body 22G.

(Modification 8)
FIG. 16 is a cross-sectional view showing a ballast according to Modification 8. The direction of the light which the illuminating device 3 emits differs in the ballast 2H which concerns on the modification 8 compared with the ballast 2 which concerns on Embodiment 1 mentioned above. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As illustrated in FIG. 16, the lighting attachment auxiliary body 22 </ b> H includes a base portion 220 </ b> H, a sandwiching portion 221, and a claw portion 228. The base 220 </ b> H is a plate-like member that faces the protrusion 219. The claw portion 228 protrudes toward the front Df at both ends in the left-right direction of the base portion 220H. More specifically, the nail | claw part 228 is arrange | positioned from the front-end | tip part of the base 220H in the position which approached the inner side of the left-right direction by the thickness of the translucent cover 24H.

  The translucent cover 24H is, for example, a plate member that is partially bent. The cross-sectional shape of the translucent cover 24H is substantially U-shaped. The translucent cover 24H is fixed to the outer surface in the left-right direction of the claw portion 228 by, for example, an adhesive. Further, in the ballast 2H, the light emitting unit 31 of the lighting device 3 is directly attached to the lighting attachment auxiliary body 22H. The translucent cover 24 </ b> H covers both the front Df and the left-right direction with respect to the light emitting unit 31.

  A part of the light emitted from the light emitting element 311 is transmitted through both the front Df and the left and right direction of the light emitting unit 31 in the front Df and the left and right direction. That is, in the ballast 2H, light is emitted toward both the front Df and the left-right direction by the illumination device 3 incorporated in the illumination attachment auxiliary body 22H. And the light which goes to both the front Df of the ballast 2H and the left-right direction irradiates the road surface of the passage 100. Thus, the illumination attachment auxiliary body 22H can incorporate the illumination device 3 so as to irradiate both the front Df and the left and right directions.

  In the ballast 2H, light is emitted both in the forward direction Df and in the left-right direction, so that the area that can be illuminated is larger than the ballast 2F according to the first embodiment and the ballast 2F according to the modified example 6. For this reason, in the fence 1 using the ballast 2H, it is possible to reduce the number of ballasts 2H necessary for setting the illuminance on the road surface of the passage 100 to a predetermined value or more. Therefore, the ballast 2H can suppress power consumption for setting the illuminance on the road surface of the passage 100 to a predetermined value or more.

(Modification 9)
FIG. 17 is a cross-sectional view showing a fence according to Modification 9. FIG. 18 is a cross-sectional view showing a ballast according to Modification 9. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As illustrated in FIG. 17, the fence 1I according to the modification 9 is a rail that is provided in the ground cover 200 between the passage 100a and the passage 100b through which a pedestrian passes, for example. For this reason, it is preferable that the ballast 2I provided in the fence 1I can irradiate both the front Df and the rear Db of the fence 1I. The passage 100a and the passage 100b may be roads through which vehicles pass. In the description of the modification 9, the direction with the passage 100a when viewed from the fence 1I is described as the front Df, and the direction with the passage 100b when viewed from the fence 1I is described as the rear Db. For example, in FIG. 17, the right side is the front Df and the left side is the rear Db.

  As shown in FIG. 18, the ballast 2I includes two lighting attachment auxiliary bodies 22 for one ballast main body 21I. More specifically, one fixing portion 210 is provided at each of both end portions of the ballast body 21 </ b> I in the front-rear direction, and the lighting attachment auxiliary body 22 is attached to each of the two fixing portions 210.

  In one lighting attachment auxiliary body 22, part of the light emitted by the light emitting element 311 passes through the translucent cover 24 disposed facing the light emitting portion 31 toward the front Df. That is, in one lighting attachment auxiliary body 22, light is irradiated toward the front Df by the lighting device 3 incorporated in the lighting attachment auxiliary body 22. And the light which goes to the front Df of the ballast 2I irradiates the road surface of the channel | path 100a.

  In the other lighting attachment auxiliary body 22, a part of the light emitted by the light emitting element 311 passes through the translucent cover 24 disposed facing the light emitting portion 31 toward the rear Db. That is, in the other lighting attachment auxiliary body 22, light is irradiated toward the rear Db by the lighting device 3 built in the lighting attachment auxiliary body 22. And the light which goes to back Db of the ballast 2I irradiates the road surface of the channel | path 100b.

  As described above, the ballast 2I according to the modified example 9 includes the illumination attachment auxiliary body 22 that can incorporate the illumination device 3 so as to irradiate the front Df with light, and irradiates the rear Db with light. Is provided with a lighting attachment auxiliary body 22 in which the lighting device 3 can be incorporated. For this reason, ballast 2I concerning modification 9 can irradiate light to both front Df and back Db.

(Modification 10)
FIG. 19 is a cross-sectional view illustrating a fence according to the tenth modification. The ballast 2J according to Modification 10 is different from the ballast 2 according to Embodiment 1 described above in the arrangement of the lighting device 3. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 19, the lighting device 3 is housed inside a lighting attachment auxiliary body 22. In the modified example 10, the power supply device 33 is disposed at the lower end portion of the lighting attachment auxiliary body 22, and the wiring 32 and the light emitting portion 31 are provided upward from the upper end portion of the power supply device 33. The wiring 34 is connected to the wiring 41J through a connector 35J such as a plug. The wiring 41J is connected to the wiring 40J disposed inside the second lateral member 12J through the wiring hole 121 provided in the second lateral member 12J. The wiring 40J is connected to a power line in the vicinity of the fence 1. As a result, AC power is supplied to the power supply device 33 through the wiring 40J, the wiring 41J, and the wiring 34.

(Modification 11)
FIG. 20 is an interior view of the fence according to Modification 11 as seen from the stairs. In addition, the same code | symbol is attached | subjected to the same component as what was demonstrated in Embodiment 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As illustrated in FIG. 20, the fence 1 </ b> K according to the modification 11 is a handrail provided in the stairs 300. The staircase 300 is a staircase provided on a footbridge, for example. The fence 1K includes the ballast 2 described in the first embodiment. Thereby, since the fence 1K can irradiate light to the road surface of the staircase 300, the safety | security with respect to the pedestrian of the staircase 300 can be improved.

  More specifically, the fence 1K includes the ballast 2 at positions corresponding to the climbing entrance 301, the landing 302, and the exit 303. Since the climbing entrance 301, the landing 302, and the exit 303 are places where the slope changes, visibility of the road surface is more important for the safety of pedestrians. Since the fence 1K is irradiated with light on the road surface where the slope changes, the safety of the stairs 300 for pedestrians can be improved.

  The ballast 2 does not necessarily have to be provided at positions corresponding to the ascending entrance 301, the landing 302, and the exit entrance 303. The ballast 2 may be provided at a position corresponding to at least one of the climbing entrance 301, the landing 302, and the exit 303. Further, the ballast 2 may be provided other than the positions corresponding to the climbing entrance 301, the landing 302, and the exit 303.

  Conventionally, when lighting is required on a pedestrian bridge, a streetlight with a lighting fixture attached to the tip of the pole has been installed. When maintenance is required for such a lighting fixture, the maintenance may be difficult because the lighting fixture is at a high position. On the other hand, if the fence 1K of the modification 11 is applied to a pedestrian bridge, work at a high place does not occur, so that maintenance can be facilitated as compared with the prior art. Moreover, since the light which goes under a footbridge is suppressed compared with the case where a streetlight is installed, possibility that the driver of the vehicle which passes along the road which passes under a footbridge will feel dazzling is reduced.

  As described above, the ballast 2 according to the first embodiment includes the ballast body 21 that can be fixed to the first lateral member 11 of the fence 1. The ballast main body 21 is a fixing for fixing the lighting attachment auxiliary body 22 in which the lighting device 3 can be incorporated so as to irradiate at least one of the front and rear directions with respect to the vertical plane 1000 along the direction in which the ballast main bodies 21 are arranged. The unit 210 is provided. Thereby, when the maintenance of the illuminating device 3 becomes necessary in the fence 1, it is possible to remove the illumination attachment auxiliary body 22 from the ballast body 21 integrally with the illuminating device 3. For this reason, the ballast 2 can improve workability in the detachment work and the attachment work of the lighting device 3.

  For example, as shown in the first embodiment, the fixing unit 210 includes a hole 211 to which the fixing member 26 for fixing the auxiliary body for lighting attachment 22 is fixed. Thereby, fixation of the auxiliary body 22 for illumination attachment with respect to the ballast main body 21 becomes easy.

  For example, as shown in the first embodiment, the fixing portion 210 includes a protrusion 219 sandwiched from both sides by the lighting attachment auxiliary body 22. Thereby, the play of the auxiliary body 22 for lighting attachment is suppressed.

  For example, as shown in the first embodiment, the fixing unit 210 includes a positioning unit 214 for regulating the position of the lighting attachment auxiliary body 22 in the front-rear direction. This facilitates the positioning of the illumination attachment auxiliary body 22 when the illumination attachment auxiliary body 22 is attached to the ballast body 21.

  For example, as shown in the first embodiment, the ballast 2 includes a ballast body 21 that can be fixed to the first lateral member 11 of the fence 1, and a lighting attachment auxiliary body 22. The lighting attachment auxiliary body 22 is fixed to the ballast body 21 and can incorporate the lighting device 3 so as to irradiate light in at least one of the front and rear directions with respect to the vertical plane 1000 along the direction in which the ballast bodies 21 are arranged. Thereby, when the maintenance of the illuminating device 3 becomes necessary in the fence 1, it is possible to remove the illumination attachment auxiliary body 22 from the ballast body 21 integrally with the illuminating device 3. For this reason, the ballast 2 can improve workability in the work of removing and attaching the lighting device.

  For example, as shown in Embodiment 1, the lighting device 3 includes a plurality of light emitting elements 311 arranged along the longitudinal direction of the tape-shaped substrate 310. Thereby, it becomes easy to reduce the size of the ballast 2.

  For example, as shown in the first embodiment, the lighting attachment auxiliary body 22 is fixed to the ballast body 21 by sandwiching protrusions 219 provided on the ballast body 21 from both sides. Thereby, the play of the auxiliary body 22 for lighting attachment is suppressed.

  For example, as shown in Modification 3, the projection mounting portion 225 provided in the lighting attachment auxiliary body 22C and the concave portion 215 provided in the ballast main body 21C mesh with each other, so that the lighting installation auxiliary body 22C becomes the ballast main body. It is fixed to 21C. As a result, the ballast 2C does not require a member for fixing the lighting attachment auxiliary body 22C to the ballast main body 21C. Therefore, the workability when the lighting attachment auxiliary body 22C is attached to the ballast main body 21C is improved. Can be improved.

  For example, as shown in the first embodiment, the ballast 2 includes a lighting device storage case 23 that can be stored in the auxiliary body 22 for lighting attachment. The lighting device 3 is attached to the lighting device storage case 23. Thereby, possibility that the illuminating device 3 will be damaged is reduced.

  For example, as shown in Embodiment 1, the ballast 2 includes a positioning member 27 for regulating the position of the lighting device storage case 23 in the front-rear direction. Thereby, the rattling of the lighting device storage case 23 is suppressed.

  For example, as shown in Modification 4 (or Modifications 5 to 8), the illumination device 3 is attached to the illumination attachment auxiliary body 22D. Thereby, since the number of parts is reduced as compared with the case where the lighting device storage case 23 is provided, the assembly of the ballast 2D is facilitated.

  For example, as shown in the first embodiment, the lighting attachment auxiliary body 22 is a light shielding member, and regulates the direction of light emitted from the lighting device 3. Thereby, the ballaster 2 can control the light direction to a preferable direction according to the traveling direction of the pedestrian or the driver.

  For example, as shown in the first embodiment, a translucent cover 24 is provided at the front end portion of the lighting attachment auxiliary body 22 in the front-rear direction. Thereby, light is irradiated toward the front-back direction from the ballast 2. For this reason, since the light which goes to a pedestrian or a driver is reduced, possibility that a pedestrian or a driver will feel dazzling is reduced.

  For example, as shown in the first embodiment, the fence 1 includes a plurality of support columns 10 arranged in one direction, a first lateral member 11 supported by the support column 10, and a first lateral member supported by the support column 10. 11 and a plurality of ballasts 2 supported by the first transverse member 11 and the second transverse member 12. At least one of the plurality of ballasts 2 is attached to the ballast main body 21 fixed to the first horizontal member 11 and the second horizontal member 12, and the ballast main body 21 along the direction in which the ballast main bodies 21 are arranged. And a lighting attachment auxiliary body 22 in which the lighting device 3 can be incorporated so as to irradiate at least one of the front and rear directions with respect to the vertical plane 1000. Thereby, when the maintenance of the illuminating device 3 becomes necessary in the fence 1, it is possible to remove the illumination attachment auxiliary body 22 from the ballast body 21 integrally with the illuminating device 3. For this reason, the fence 1 can improve workability | operativity in the removal operation | work of an illuminating device, and attachment work.

  For example, as shown in the first embodiment and the tenth modification, the power supply device 33 included in the lighting device 3 via the wiring 40 (or the wiring 40J) passed through the first horizontal member 11 or the second horizontal member 12J. Is supplied with power. Thereby, since the number of wiring visible from the outside is reduced, the design of the fence 1 is improved.

  For example, as shown in the first embodiment and the tenth modification, the power supply device 33 is disposed inside the lighting attachment auxiliary body 22. Thereby, since it becomes easy to produce a space inside the 1st horizontal member 11 or the 2nd horizontal member 12J, construction of the wiring 40 (or wiring 40J) becomes easy.

  For example, as shown in the modified example 1, in the fence 1, the lighting attachment auxiliary body 22 of the ballast body 21 is provided in the ballast 2 </ b> A corresponding to the position where it is not necessary to irradiate light among the plurality of ballasts 2. The fixing part 210 for fixing is exposed. When not all the ballasters 2 need to irradiate light, the ballast 2A is used, so that the interval between the ballasters 2 is maintained and the illuminance on the road surface can be easily adjusted. Moreover, the auxiliary body 22 for illumination attachment is easily attached to the ballast 2A as needed.

  For example, as shown in the modified example 2, the fence 1 includes a dummy member 2B supported by the first lateral member 11 and the second lateral member 12 at a position where it is not necessary to irradiate light. The cross-sectional shape obtained by cutting the dummy member 2B along a plane perpendicular to the longitudinal direction is a cross-sectional shape obtained by cutting the ballast 2 having the ballast body 21 and the lighting attachment auxiliary body 22 along a plane perpendicular to the longitudinal direction. The same. When all the ballasters 2 do not have to irradiate light, the dummy member 2B is used, so that the interval between the ballasters 2 is maintained and the illuminance on the road surface can be easily adjusted. Furthermore, the appearance of the dummy member 2B is similar to the appearance of the ballast 2. For this reason, even when the ballast 2 and the dummy member 2B are mixed in the fence 1, the design of the fence 1 is improved.

  For example, as shown in the modification 11, the fence 1K is provided on the staircase 300. Thereby, since the fence 1K can irradiate light to the road surface of the staircase 300, the safety | security with respect to the pedestrian of the staircase 300 can be improved.

  For example, as shown in the eleventh modification, the ballast 2 having the ballast body 21 and the lighting attachment auxiliary body 22 is disposed at a position corresponding to the climbing entrance 301, the exit 303 or the landing 302 of the staircase 300. Thereby, since light is irradiated to the road surface of the place where the slope changes, the fence 1K can improve the safety | security with respect to the pedestrian of the staircase 300. FIG.

(Embodiment 2)
FIG. 21 is a front view showing a repair fence according to the second embodiment. 22 is a cross-sectional view taken along line EE in FIG. 23 is a cross-sectional view taken along line FF in FIG. The fence 1L according to the second embodiment is a fence obtained by modifying an existing fence, and is, for example, a handrail provided in a passage 100 through which a pedestrian passes. Note that the fence 1L may be a handrail provided on a road through which the vehicle passes.

  As shown in FIG. 21, the fence 1L includes a support column 10L, a first lateral member 11L, a second lateral member 12L, and a ballast 2L. A plurality of pillars 10L are provided along the edge of the passage 100, and are fixed to the ground cover 200 via pedestals 101L as shown in FIG. The plurality of support columns 10L are arranged at a predetermined interval from each other.

  The first lateral member 11L is a long member extending in the horizontal direction and spanned between adjacent struts 10L. The first lateral member 11L is fixed to the support column 10L by a fastening member such as a bolt. The second lateral member 12L is a long member that is long in the horizontal direction and spans between adjacent struts 10L. The second lateral member 12L is disposed below the first lateral member 11L, and is fixed to the column 10L by a fastening member such as a bolt.

  As shown in FIG. 21, the ballast 2L is a long member that is supported by the first lateral member 11L and the second lateral member 12L and is long in the vertical direction. A plurality of ballasts 2L are provided along the direction in which the columns 10L are arranged. The plurality of ballasts 2L are arranged at a predetermined interval from each other. A repair unit 5 is attached to the ballast 2L.

  As shown in FIG. 23, the repair unit 5 includes an adapter 6 and a lighting unit 50. The adapter 6 is fixed to the ballast 2L, and the lighting unit 50 is fixed to the adapter 6. That is, the illumination unit 50 is fixed to the ballast 2L through the adapter 6.

  The adapter 6 is a member for attaching the lighting unit 50 to the ballast 2L. That is, the adapter 6 can be rephrased as a connection device or an attachment accessory. The adapter 6 is made of, for example, a structural aluminum alloy. The adapter 6 includes a first holding part 61, a second holding part 63, a joining part 62, and a connecting part 64. The 1st clamping part 61 and the 2nd clamping part 63 are arrange | positioned so that the ballast 2L may be clamped from the both sides of the left-right direction. The joining portion 62 connects the ends of the front Df of the first clamping portion 61 and the second clamping portion 63 to each other. The connecting part 64 protrudes from the end of the rear Db of the second clamping part 63 to the side opposite to the first clamping part 61. The connecting portion 64 is provided with a hole 66 penetrating in the front-rear direction.

  The first clamping unit 61 includes a hole 65 penetrating in the left-right direction and a fastening member 69 fixed to the hole 65. The fastening member 69 is, for example, a clamping screw. The fastening member 69 protrudes from the surface of the first clamping part 61 facing the ballast 2L and is in contact with the ballast 2L. The fastening member 69 presses the ballast 2L against the second clamping part 63. The longer the length that the fastening member 69 protrudes from the first clamping portion 61, the greater the force with which the ballast 2L is pressed. The adapter 6 is fixed to the ballast 2L by friction generated between the fastening member 69 and the ballast 2L and between the second clamping part 63 and the ballast 2L.

  The lighting unit 50 includes a first support member 51, a second support member 52, a lighting device storage case 53, a translucent cover 54, and a buffer member 55.

  The first support member 51 is a member for ensuring the strength required for the lighting unit 50 and supports the second support member 52. The first support member 51 is made of, for example, a structural aluminum alloy. The first support member 51 is, for example, a cylindrical extruded shape member. The first support member 51 includes a hole 512 at a position overlapping the hole 66 of the connecting portion 64. The first support member 51 is connected to the adapter 6 by a fastening member 59 fixed to the hole 66 and the hole 512.

  The first support member 51 includes a base portion 518 and a fixing portion 510. The base 518 is disposed on the rear Db of the first support member 51. For example, the fixing portion 510 is provided integrally with the base portion 518 on the front Df of the base portion 518. The fixing unit 510 includes a protrusion 519, a hole 511, and a positioning unit 514.

  The protrusion 519 protrudes from the end of the front Df of the base 518 toward the front Df. For example, the cross-sectional shape of the protrusion 519 is a substantially U shape opposite to the substantially U shape of the base 518. More specifically, the protrusion 519 includes two side surfaces orthogonal to the left-right direction and an end surface orthogonal to the front-rear direction and connecting the two side surfaces. The hole 511 is provided on the side surface of the protrusion 519. For example, the width in the left-right direction of the protrusion 519 is constant and smaller than the width in the left-right direction at the end of the front Df of the base 518. Thereby, a step is generated between the base 518 and the protrusion 519. For this reason, the positioning part 514 is formed in the edge part of the front Df of the base part 518 as an end surface orthogonal to the front-back direction. In other words, the member of the first support member 51 on the rear Db side of the positioning portion 514 is the base portion 518, and the member of the first support member 51 on the front Df side of the positioning portion 514 is the protrusion 519.

  The second support member 52 is a housing in which the lighting device 3 can be incorporated, and is attached to the first support member 51. That is, the second support member 52 is a member for attaching the lighting device 3 to the first support member 51. The second support member 52 is a substantially H-shaped extruded shape member made of, for example, a structural aluminum alloy. The second support member 52 includes a base portion 520, a sandwiching portion 521, and a claw portion 523. The base 520 is disposed on the front Df of the end surface of the protrusion 519 of the first support member 51. For example, the cross-sectional shape of the base 520 is a substantially U shape that opens toward the front Df. Two sandwiching portions 521 are provided. Each of the two sandwiching portions 521 protrudes from the left and right ends at the end of the rear Db of the base 520 toward the rear Db. The sandwiching portion 521 is in contact with the side surface of the protrusion 519. That is, the pair of sandwiching portions 521 sandwich the protrusion 519 from both sides. The thickness of the clamping part 521 in the left-right direction is equal to the size of the step between the base part 518 and the protrusion 519 in the first support member 51. Thereby, a step is hardly generated between the first support member 51 and the sandwiching portion 521. Further, the length in the front-rear direction of the sandwiching portion 521 is equal to the length in the front-rear direction of the protrusion 519 of the first support member 51. As a result, the tip of the clamping part 521 is in contact with the positioning part 514 of the first support member 51. The positioning part 514 regulates the position of the second support member 52 in the front-rear direction. Further, a hole 522 is provided in the sandwiching portion 521. The hole 522 is disposed so as to overlap the hole 511 provided in the protrusion 519. The fixing member 56 is fixed to the hole 511 and the hole 522. The fixing member 56 is, for example, a bolt, and more specifically, an ultra-low head bolt. Thereby, the second support member 52 is connected to the first support member 51. The nail | claw part 523 protrudes toward the inner side of the left-right direction in the edge part of the front Df of the base 520. FIG.

  The lighting device storage case 53 is a member for facilitating the work of placing the lighting device 3 inside the second support member 52 and protecting the lighting device 3. The lighting device storage case 53 is made of, for example, a synthetic resin. The cross-sectional shape of the lighting device storage case 53 is a substantially U-shaped member that opens toward the front Df. The lighting device storage case 53 is disposed inside the base 520 of the second support member 52. The light emitting unit 31 of the lighting device 3 is attached to the bottom surface of the lighting device storage case 53. Further, a positioning member 57 is provided at a position facing the bottom surface of the lighting device storage case 53 in the base portion 520. The positioning member 57 is, for example, a hexagon socket set screw, and is attached to a female screw 524 provided in the base 520. The positioning member 57 protrudes from the female screw 524 to the front Df, and pushes the lighting device storage case 53 toward the front Df. Accordingly, the lighting device storage case 53 is positioned by being sandwiched between the claw portion 523 and the positioning member 57 via the translucent cover 54 and the buffer member 55. Since the positioning member 57 presses the lighting device storage case 53, the backlash of the lighting device storage case 53 is suppressed.

  The translucent cover 54 is a member that transmits light from the light emitting unit 31 in a predetermined direction. The translucent cover 54 is a plate-like member made of, for example, polycarbonate. The translucent cover 54 is disposed at the front Df end of the second support member 52 and covers the opening of the lighting device storage case 53. The translucent cover 54 is disposed in parallel with the vertical surface 1000 and faces the light emitting unit 31 provided on the bottom surface of the lighting device storage case 53. The translucent cover 54 is fixed to the second support member 52 by being pressed against the claw portion 523 by the lighting device storage case 53.

  The buffer member 55 is made of, for example, a synthetic resin. The buffer member 55 is disposed between the translucent cover 54 and the claw portion 523. The buffer member 55 is deformed according to the magnitude of the applied force, thereby filling the space between the translucent cover 54 and the claw portion 523.

  Note that the fixing member 56 is not necessarily a bolt, and may be a rivet, for example. Further, the positioning member 57 is not necessarily a hexagon socket set screw, and may be a flat head screw, for example. Moreover, the translucent cover 54 does not necessarily need to be a polycarbonate, for example, an acrylic etc. may be sufficient as it. Further, the buffer member 55 is not necessarily a synthetic resin, and may be a synthetic rubber, for example. Further, the buffer member 55 may not be provided.

  A part of the light emitted from the light emitting unit 31 is transmitted toward the front Df through the translucent cover 54 disposed to face the light emitting unit 31. That is, in the illumination unit 50, light is irradiated toward the front Df by the illumination device 3 built in the second support member 52. And the light which goes to front Df of the illumination unit 50 irradiates the road surface of the channel | path 100. FIG. Thus, the illumination unit 50 can incorporate the illumination device 3 so as to irradiate the front Df with light.

  The method of repairing the fence 1L using the repair unit 5 is as follows. That is, first, the adapter 6 is attached to the ballast 2L. Thereafter, the lighting unit 50 is attached to the adapter 6 by the fastening member 59. That is, the method of repairing the fence 1L using the repair unit 5 includes a step of attaching the lighting unit 50 to the existing ballast 2L via the adapter 6. Moreover, the 1st support member 51 and the 2nd support member 52 are assembled in advance, for example in the factory.

  The adapter 6 is not necessarily a long member that is long in the vertical direction, that is, a through member. For example, the adapter 6 may be attached to the upper end portion and the lower end portion of the ballast 2L. Further, the first support member 51 and the second support member 52 may not be assembled in advance. For example, in the field, after the first support member 51 is attached to the adapter 6 by the fastening member 59, the second support member 52 may be attached to the first support member 51 by the fixing member 56.

  In addition, in the fence 1L which concerns on Embodiment 2, the structure of the modifications 3-9 of Embodiment 1 mentioned above may be applied, for example. That is, in the fence 1L, the second support member 52 may be attached to the first support member 51 by a mechanical clamp method. Further, in the fence 1L, the lighting device storage case 53 may not be provided, and the light emitting unit 31 of the lighting device 3 may be directly attached to the second support member 52. Further, in the fence 1L, the translucent cover 54 may be attached to the second support member 52 by a mechanical clamp method. In the fence 1L, the illumination unit 50 may irradiate light in one of the front Df and the left-right direction, or may irradiate light in both the front Df and the left-right direction. Moreover, in the fence 1L, two illumination units 50 are provided, and each of the two illumination units 50 may irradiate both the front Df and the rear Db.

  As described above, the fence 1L according to the second embodiment is a fence obtained by renovating an existing fence, and the existing ballast 2L has a front-rear direction with respect to the vertical plane 1000 along the direction in which the ballasts 2L are arranged. An illumination unit 50 capable of incorporating the illumination device 3 is attached so as to irradiate at least one of the lights. Thereby, when the maintenance of the illuminating device 3 becomes necessary in the fence 1L, the illuminating unit 50 can be detached from the ballast 2L integrally with the illuminating device 3. For this reason, the fence 1L can improve workability | operativity in the removal operation | work and attachment operation | work of an illuminating device.

  In addition, the repair unit 5 according to the second embodiment is a repair unit attached to the existing ballast 2L. The repair unit 5 includes an adapter 6 and a lighting unit 50. The adapter 6 includes a first clamping part 61 and a second clamping part 63 that sandwich the ballast 2L from both sides, and a connecting part 64 that projects from the second clamping part 63 to the opposite side of the first clamping part 61. The illumination unit 50 is fixed to the connecting portion 64, and can incorporate the illumination device 3 so as to irradiate at least one of the front and rear directions with respect to the vertical plane 1000 along the direction in which the ballasts 2L are arranged. Thereby, when the maintenance of the illuminating device 3 becomes necessary in the fence 1L, the illuminating unit 50 can be detached from the ballast 2L integrally with the illuminating device 3. For this reason, the repair unit 5 can improve the workability | operativity in the removal operation | work of the illuminating device 3, and an attachment operation | work.

  In the repair unit 5 according to the second embodiment, the first clamping unit 61 includes a fastening member 69 that protrudes from the surface facing the ballast 2L and is in contact with the ballast 2L. The adapter 6 is fixed to the ballast 2L by friction generated between the fastening member 69 and the ballast 2L and between the second clamping part 63 and the ballast 2L. This eliminates the need for processing such as making a hole in the ballast 2L, and thus improves workability when attaching the repair unit 5 to the ballast 2L.

  The renovation method according to the second embodiment is a renovation method of an existing fence, and irradiates at least one of the front and rear directions with respect to the vertical plane 1000 along the direction in which the ballasts 2L are arranged on the existing ballast 2L. The process of attaching the illumination unit 50 which can incorporate the illuminating device 3 is included. When maintenance of the illuminating device 3 becomes necessary in the fence 1L renovated by this refurbishing method, the illuminating unit 50 can be detached from the ballast 2L together with the illuminating device 3. For this reason, the repair method can improve the workability | operativity in the removal operation | work and attachment operation | work of the illuminating device 3 at the time of the maintenance of the fence 1L.

  A streetlight with a lighting fixture attached to the tip of the pole may be installed around the fence of the pedestrian bridge that has been provided. If a rehabilitation using the above-described refurbishment unit 5 is performed on a fence of a pedestrian bridge that has been provided conventionally, the streetlight becomes unnecessary, and thus the streetlight can be removed. For this reason, the refurbishment using the refurbishment unit 5 contributes to a reduction in the maintenance work of the streetlight which is a work at a high place. Moreover, since the light which goes under a footbridge is suppressed compared with the case where a streetlight is installed, possibility that the driver of the vehicle which passes along the road which passes under a footbridge will feel dazzling is reduced.
