Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination box for a mobile conveyance device and a method for manufacturing the same, and more particularly, to an illumination box for a mobile conveyance device that stores an illumination device installed on the bottom or side of an escalator, a mobile walkway, And a manufacturing method thereof. In addition, although the escalator whose inclination angle of a slope is about 30 degree | times and the moving walk for horizontal movement are common for the mobile conveyance apparatus in this invention, a moving walk, a travolator (brand name), a travator are also used. (Product name) and a mobile transfer device called a competitor (product name) are also included.

  Usually, a mobile conveyance device such as an escalator (hereinafter referred to as an escalator) has a step and a riser, and the step and the riser are formed so as to circulate on an endless track. Transport. This circulating moving step and riser are supported by a truss. As shown in FIG. 8, FIG. 9 and FIG. 10, there are inner plates made of transparent tempered glass or stainless steel on the decks on both sides of the step and riser. The riser, truss, and the like below the escalator are covered with a side plate 11 and a bottom plate 12. Further, as shown in FIG. 8, when the escalators are overlapped and the lower part is exposed to the outside, the lighting device 13 is also attached to the bottom surface of the escalator, and in some cases, the side surface.

  As shown in FIG. 10, the lighting device 13 is fixed to a back surface of an oil pan 20 installed at a lower portion of a truss 18 inside the escalator by a lighting device fixing member 19 such as an L-shaped steel, a round bar, or a turnbuckle. Yes. Usually, the lighting device fixing member 19 is attached to the reinforcing member 7 of the lighting box 1 by welding or the like. A lighting fixture 16 is installed in the lighting box 1 and the lower part of the lighting box 1 is covered with a white or colorless transparent plate 17 such as an acrylic plate. Usually, the lighting box 1 is made of a steel plate having a U-shaped cross-sectional shape. Conventionally, this lighting box has been manufactured by integrally forming a single steel plate by sheet metal processing so as to have a U-shaped cross-sectional shape. Until now, technical attention has not been paid to exterior bodies such as lighting devices, side plates, and bottom plates compared to the escalator itself, but recently strict management of manufacturing costs and quality is required. Accordingly, research has been conducted on a method for attaching side plates and bottom plates (Patent Document 1). However, little attention was paid to the improvement of the lighting box.

Japanese Patent Laid-Open No. 11-236182

  As described above, the escalator lighting box has a relatively simple structure and a simple installation method on the escalator, and thus has not been paid much attention. However, it is not preferable that the escalator, which is an apparatus used for a long time, is corroded even inside. In particular, the lighting box covers the luminaire, and a uniform and beautiful reflecting surface must be maintained for a long time. Therefore, sufficient consideration was necessary for painting. However, since the conventional lighting box was coated after the steel sheet was formed into a U shape, it was difficult to mechanically paint the inner reflective surface, and it was painted by hand.

An object of the present invention is to improve the painting method of such an illumination box, to provide an illumination box with high quality and stable quality, and to rationalize the production work.

In order to solve the above-mentioned problems, it has been found that a method in which the U-shaped top plate portion and the side plate portion of the lighting box are separately manufactured and painted in a state that is easy to paint and then assembled is preferable. Then, by providing a special engagement portion when assembling the top plate and the side plate, an illumination box that can be manufactured more simply than the conventional illumination box integral molding was invented, and the following invention was completed.
(1) In the junction between the top plate and the side plate of the lighting box formed by joining the top plate and the side plate, a projection is provided on one of the top plate and the side plate, a projection insertion hole is provided on the other, and the projection is the projection insertion hole. It is an illumination box for a mobile conveyance device that is inserted and further protrudes from the protrusion insertion hole to the opposite side and the top plate and the side plate are locked.
(2) The movement according to (1), wherein the protrusion is formed at an end of the top plate or the side plate, and the locking form of the top plate and the side plate is twisting or bending of the tip of the protrusion protruding from the protrusion insertion hole. It is an illumination box for a type transfer device.
(3) The protrusion is formed at the end of the top plate or the side plate, the tip of the protrusion protruding from the protrusion insertion hole extends from the base of the protrusion, and the expanded tip of the protrusion is hooked on the side plate or the top plate. It is the illumination box for mobile conveyance apparatuses as described in (1).
(4) In any one of (1) to (3), a substantially gate-shaped reinforcing member is disposed so as to straddle the outer side along a substantially gate-shaped cross-sectional shape formed by the top plate and the two side plates. This is an illumination box for a mobile transfer device.
(5) It is a manufacturing method of the illumination box for mobile conveyance apparatuses in any one of (1)-(4) assembled after each producing and painting a top plate and a side plate.
(6) The manufacturing method of the illumination box for the mobile transport device according to any one of (1) to (4), wherein the top plate and the side plate are respectively prepared and coated, and then incorporated into the mobile transport device.

  The illumination box for a mobile conveyance device of the present invention has a structure in which a flat plate or a substantially flat top plate and a side plate are assembled and manufactured, and the coating may be performed on the substantially flat top plate and the side plate. Therefore, it is easy to paint, easy to finish uniformly, machine coating can also be simplified, and the entire lighting box for the mobile transport device is easy to manufacture. In particular, low cost and stable quality coating is possible by mechanical coating. Furthermore, since the top plate and the side plate can be stacked and transported efficiently as a plate material, it can be easily transported and handled to the escalator installation site. To assemble the lighting box, simply insert the protrusion into the protrusion insertion hole and, depending on the case, just bend the tip of the protrusion with pliers, etc., and it can be manufactured at the factory or on the escalator installation site. It can also be produced. In addition, when a defect occurs in a part of the lighting box and it is repaired or replaced, it is possible to easily remove and repair or replace only one part such as the top plate or side plate, not the entire lighting box. Can do.

  In the mobile transfer device having the lighting box of the present invention, there are devices with various names such as escalators, travolators (product names), travatars (product names), competitors (product names), moving walkways, moving walkways, For convenience of explanation, an escalator lighting box will be described as a representative example. However, the illumination box for the mobile transport device according to the present invention does not exclude the illumination box for the mobile transport device other than that for the escalator, and includes all the illumination boxes for the device.

  The lighting box for escalators of the present invention comprises at least a top plate and two side plates. As shown in FIG. 1, these plates have side plates 3 arranged on both side surfaces of the top plate 2 and have a substantially U-shaped or gate shape in cross section. In order to lock the top plate 2 and the side plate 3, a projection 4 is provided on one plate of the joint portion, and a projection insertion hole 5 is provided on the other plate, and the projection 4 is provided in the projection insertion hole 5. It is inserted and protrudes from the protrusion insertion hole to the opposite side. Thereby, the top plate and the side plate are locked. The engagement portion where the projection 4 and the projection insertion hole 5 are combined may be provided at one location at the junction between the top plate 2 and the side plate 3, but usually at least two locations are preferred. What is necessary is just to determine the number of latching parts by the length of the junction part of the top plate 2 and the side plate 3. FIG. Usually, it is preferable to provide a locking portion every 0.5 to 2 m. The top plate 2 and the side plate 3 may be bent at a substantially right end or folded to increase the strength of the lighting box. In particular, since a transparent plate such as an acrylic plate is installed at the end of the side plate opposite to the joint with the top plate, the side plate is usually folded inward. The length of one lighting box is often 2 to 3m, and since it is usually connected to the next lighting box, it is not necessary to provide a side plate to close the side wall in the longitudinal direction. If there is no box, a side plate in the longitudinal direction may be provided.

  The lighting box of the present invention is characterized by the engagement structure between the top plate and the side plate. The engagement of the joint between the top plate and the side plate has a structure in which a projection and a projection insertion hole are combined. If described according to FIG. 1, a substantially rectangular plate-like projection formed on the side surface of the top plate 2 4 is inserted into the protrusion insertion hole 5 at a position corresponding to the protrusion 4 of the side plate 3 and protrudes to the opposite side. A part of the protruding protrusion is bent, and the top plate 2 and the side plate 3 are securely locked so as not to come off. In the figure, there are two locking portions of the combination of the protrusion 4 and the protrusion insertion hole 5 on one side plate. The opposite side plate and top plate are also locked in the same structure. It is desirable to arrange protrusions at intervals of 20 to 30 cm in the actual lighting box of the present invention.

FIG. 1 shows an example of the lighting box of the present invention, but a specific example of the shape of the protrusion and the locking structure in the present invention is shown. The examples described here are representative and do not deny any other protrusion shape or locking structure, but have any structure as long as it has the structure of the present invention and fulfills the object of the present invention. But you can. For example, there is no need to bend the tip of the protrusion, and the protrusion may be a rod instead of a plate. Of course, it is necessary to adjust the protrusion insertion hole so that the protrusion can be inserted.

  FIG. 2A shows a state in which the protrusion 4 protrudes from the protrusion insertion hole 5 of the side plate 3. After the protrusion 4 is inserted into the protrusion insertion hole 5, its tip is twisted clockwise around the axis in the normal direction with respect to the side plate so that it does not come off the protrusion insertion hole 5. Thereby, the side plate 3 is locked so as not to be detached from the projection 4, that is, the top plate 2 on which the projection is formed. The lower part of FIG. 2 shows an example of the shape of the protrusion having such a structure that the top plate and the side plate are locked by twisting the tip as described above or bending it as shown in FIG. These protrusions are plate-shaped, a is an L-shaped protrusion, b is a T-shaped protrusion, c is a mushroom-shaped protrusion, and d is an L-shaped combined protrusion. The type d is convenient because the width of the projection insertion hole may be formed in accordance with the lateral width of the projection, and there is no displacement in the longitudinal direction of the side plate and the top plate. For the a type, the same effect as the d type can be obtained if the two protrusions are installed in opposite directions as shown in FIG.

  FIG. 3B shows a structure in which the protrusion 4 protrudes from the protrusion insertion hole 5 of the side plate 3, and the protrusion 4 is bent so that the distal end portion thereof is substantially parallel to the side plate after being inserted into the protrusion insertion hole 5. ing. Thereby, the side plate 3 is locked so as not to be separated from the projection 4, that is, the top plate 2 on which the projection is installed. The shape of the protrusion suitable for such a locking method is shown in e, f, and g of FIG. “e” indicates a rectangular plate shape, “f” indicates a semicircular disk shape, and “g” indicates a state in which a triangular plate-like protrusion is installed on the side surface of the top plate. Such a locking structure can also be applied to protrusions having shapes such as a, b, c, and d shown in FIG.

  In FIG. 4C, the protrusion 4 protrudes from the protrusion insertion hole 5 of the side plate 3. After the protrusion 4 is inserted into the protrusion insertion hole 5, the top plate 2, that is, the protrusion 4 extends in the longitudinal direction of the protrusion insertion hole 5 with respect to the side plate 3. (In FIG. 4C, the protrusion 4 moves to the left side of the side plate 3) relatively moves in equilibrium, and the hook-like portion at the tip of the protrusion 4 is hooked so as not to come off the side plate. . Thereby, the side plate 3 and the protrusion 4, that is, the top plate 2 are locked so as not to come off. It is particularly preferable as a locking effect if the hook-like portion at the tip of the protrusion 4 is structured to be engaged with the protrusion engaging portion 6 formed on the side plate as shown in FIG. When the protrusion 4 and the side plate 3 are relatively moved in balance along the protrusion insertion hole 5 and the protrusion 4 is hooked to the protrusion hooking portion 6, the elasticity of the plate-like protrusion 4 is used to In C of 4, the protrusion 5 is pressed upward or downward to move in parallel, and the hook-shaped portion at the tip is hooked to the protrusion hooking portion 6. In FIG. 4, h, i, and j at the bottom indicate the shapes of protrusions suitable for such a locking structure. i and j are not very effective in forming the protrusion locking portion 6. Note that such a locking structure can also be applied by protrusions having shapes such as b and c shown in FIG. The protrusions as described above can be easily formed by leaving a part of the steel plate as a protrusion when the top plate 1 or the side plate 3 is manufactured.

  The protrusion i in FIG. 4 has the same shape as the protrusion a in FIG. However, in the case of the structure shown in FIG. 4C, pay attention to the direction of the tip of the protrusion protruding in an L shape. The escalator is usually structured such that one is high and the other is low. Such an escalator lighting box is also installed with an inclination in its longitudinal direction. Therefore, when the member directly fixed to the escalator body (such as a truss) is the side plate 3 as shown in FIG. 10, for example, the top plate 2 is supported by the side plate 3. In such a case, it arrange | positions so that the part which protrudes in the L shape of the front-end | tip of the processus | protrusion 4 may become the lower side of inclination. In FIG. 4, it is assumed that the left side of the side plate 3 is lower, but by doing so, the L-shaped projection 4 is locked to the left side of the projection insertion hole 5 due to the weight of the top plate. 4 is securely locked to the side plate 3. When the member directly fixed to the escalator body is a top plate, the tip of the L-shaped protrusion is reversed. In addition, when both the top plate and the side plate are directly fixed to the escalator body, or when the top plate and the side plate are fixed by a reinforcing member to be described later, such consideration is not necessary. There may or may not be some bending or twisting as shown.

  So far, as shown in FIG. 1, an example of an illumination box having a structure in which a projection 4 is provided on the side surface of the top plate 2 and a projection insertion hole 5 is provided at a joint portion with the top plate near the side surface of the side plate 3 has been described. However, the normal lighting box has an elongated shape with a cross section of about 20 to 30 cm, and is installed in a narrow position below the escalator. Therefore, depending on the conditions for assembling the lighting box and the conditions for mounting on the escalator, the position of the tip of the protrusion is set. What kind of shape should be made depends on the situation. From the lighting box manufacturer, it is effective to prepare a structure that can meet any requirements. Various examples of the shape and structure of the protrusions are shown as described above. The arrangement of the protrusions is basically the arrangement shown in FIGS. The k, l, and m types in FIG. 5 have a structure in which a protrusion is provided on the top plate 2 and the tip of the protrusion is disposed on the side surface. The k and l types can be used when it is inconvenient for attaching a lighting fixture or the like if the projection tip is inside the lighting box. Compared with the k type, the l type has a more rigid top plate and requires relatively little attention when installing the lighting fixture. For the m type, it is convenient to remove and attach the side plate of the lighting box after installing the top plate of the escalator. The n, o, and p types have a protrusion on the side plate side and a protrusion insertion hole on the top plate side. Each of them may be used properly in consideration of manufacturing, mounting and maintenance characteristics. In the figure, all the protrusions 4 are installed on the side surfaces of the top plate or the side plate, but they are not necessarily the side surfaces. What is necessary is just to install in the junction part of both members of the side surface vicinity. Further, the protrusion need not be flat, but may be rod-shaped, mushroom-shaped, or other complicated shapes.

  Next, a description will be given of an illumination box that includes a reinforcing member and in which the top plate and the side plate are difficult to deform. The reinforcing member 7 has a structure that matches the cross-sectional shape of the lighting box 1 as shown in FIG. That is, the reinforcing member 7 is disposed so as to straddle the lighting box on the outer side of the top plate 2 and the side plate 3 of the lighting box 1. The reinforcing member is substantially gate-shaped or U-shaped like 7a, 7b or 7c in FIG. 6, and 7a and 7b have a shape in which three L-shaped steels are fixed by welding or the like. 7a is a structure in which the L-shaped steel of the top plate reinforcing portion 8 in the middle and the side plate reinforcing portions 9 at both ends are fixed back to back, and 7b is a structure in which three L-shaped steels are protruding in the same direction. Each plane parallel to the U-shaped plane provides rigidity to the lighting box, and a plane perpendicular to the plane (the flange portion) fixes the top plate and the side plate. 7c is a shape in which notches are formed in the inner corners of the U-shaped steel sheet, and about half of the inner surface of the U-shaped steel sheet is raised 90 degrees in the same direction. The type 7c is convenient because it is easy to manufacture and the material can be steel plate for lighting box. Screw holes 10 are provided in the flange portions of the respective reinforcing members 7a, 7b, and 7c. After the reinforcing member 7 is attached to the lighting box 1 as shown in FIG. By doing in this way, even if the lighting box 1 is made of a thin steel plate, it becomes a rigid and easy-to-handle lighting box. In addition, the side plate reinforcement part of a reinforcement member does not need to be the same length as a side plate. Rather, as shown in FIG. 7, it may be more convenient to keep the side plate 3 shorter than the side plate 3 because it does not interfere with the mounting of the lighting box to the escalator body or the escalator bottom plate. Moreover, this reinforcement member can be applied also as an attachment member to an escalator main body, and a connection member which connects adjacent lighting boxes. In that case, it is preferable that the reinforcing member 7 has a structure in which the flange portions protrude from the left and right sides of the U-shaped surface as in the type 7a of FIG.

  FIG. 8 shows an example in which two lighting devices 13, that is, lighting boxes 1 are arranged in a column on the bottom surface of the escalator. This lighting box may be in one row or may be arranged at the position of the side plate 11. In some cases, the lighting box may be partially arranged rather than from the top to the bottom of the escalator.

  In such an illumination box, a top plate and a side plate are respectively manufactured, and a projection or a projection insertion hole is set on the top plate and a side plate, and then painting is performed. The reinforcing member is also painted separately. The coating may be performed by any method, but mechanical coating is preferable. Although the top plate and the side plate may have some bent portions at the end, they are almost flat and can be easily machine-coated. Not only is it cheaper and simpler than hand-painting and painting with an expensive robot, it also has the advantage that a uniform and high-quality coating can be easily obtained. Each painted member may be assembled at the factory or escalator installation site, and installed in the escalator in the same manner as before. When assembling, if it is not necessary to deform the protrusion, no tool is required. Even if the protrusions are twisted or bent, there may be no jig, but a tool such as pliers is sufficient. Therefore, it is also easy to assemble while attaching each member of the painted lighting box directly to the bottom of the escalator at the escalator installation site. Furthermore, it is possible to work easily even when repairing one part.

  The illumination box for a mobile transport device of the present invention can be applied to any mobile transport device that requires an illumination device on the bottom or side. In particular, it is effective to use escalators that require lighting at the bottom, such as escalators installed in the lobby, and escalators for buildings with three or more floors that are installed in multiple escalators.
