Description

  The present invention relates to a wiring rail capable of supplying power at an arbitrary position in the longitudinal direction, and a lighting device using the wiring rail.

  Conventionally, wiring rails have been installed on ceilings, wall surfaces, etc., and lighting fixtures can be attached and the lighting fixtures can be moved to any position along the longitudinal direction of the wiring rails. But it can be electrically connected to power the luminaire.

  A general wiring rail has a linear long duct, and a pair of conductors are disposed along the longitudinal direction inside the duct (see, for example, Patent Document 1). Also, when installing the wiring rails in different directions, connect the two wiring rails installed in different directions with joint parts, and electrically connect the conductors of the two wiring rails with the joint parts. is doing.

In addition, there is a wiring rail in which a duct is formed of a flexible plastic material and can be arbitrarily bent. In this wiring rail, when the wiring rail is bent, the inner peripheral side of the conductor is compressed and the outer peripheral side is expanded, so that a plurality of slits are provided to absorb the displacement difference between the inner peripheral side and the outer peripheral side. A conductor having a complicated structure is used. Further, a plurality of conductors are arranged in parallel corresponding to the direction in which the wiring rail is bent (see, for example, Patent Document 2).
Japanese Patent Application No. 2006-302665 (3rd page, FIG. 1-2) JP 10-507571 (page 8-12, FIG. 1-12)

  However, when installing the wiring rails in different directions, connecting the two wiring rails installed in different directions with joint parts requires parts that are different from the wiring rails, and the bending angle and size There is a problem that cannot be set freely.

  In addition, in the wiring rail in which the duct and the conductor can be arbitrarily bent, the inner circumference side of the conductor is compressed and the outer circumference side is expanded when the wiring rail is bent, so that the displacement between the inner circumference side and the outer circumference side is increased. In order to absorb the difference, it is necessary to use a conductor having a complicated structure provided with a plurality of slits. Furthermore, since a plurality of conductors are arranged in parallel corresponding to the direction in which the wiring rail bends, the conductors arranged in parallel serve as resistance against bending of the wiring rail, and the wiring rail can be bent sufficiently. There is a risk that the conductor may be damaged by being bent forcibly.

  The present invention has been made in view of such points, and provides a wiring rail that can be freely bent and installed, and that can simplify the structure of a conductor, and a lighting device using the wiring rail. Objective.

  The wiring rail according to claim 1 is formed in an elongated shape and has a flexible rail body that can be bent in a predetermined direction intersecting the longitudinal direction thereof; and a side surface of the rail body in the bendable direction; And a pair of conductors arranged in a direction intersecting the bendable direction of the rail body and along the longitudinal direction of the rail body.

  The rail body is formed of a flexible material such as soft vinyl chloride resin, for example, and the cross-sectional width in the bendable direction is reduced and the cross-sectional width in the direction intersecting the bendable direction is increased. Etc. so that it can be bent mainly in a bendable direction. The rail body is attached to an installation surface such as a ceiling or a wall surface using a fixture or a screw.

  For example, a single conductor such as a copper wire is used as the pair of conductors, and the conductors are embedded and installed on the side surfaces of the rail body in a bendable direction with a part thereof exposed. For example, a flexible substrate may be used as the conductor, and the conductor may be disposed on a side surface of the rail body in a bendable direction.

  Then, the rail body is formed to be bendable, and a pair of conductors are arranged on the side surfaces of the rail body in the bendable direction so as to intersect with the bendable direction of the rail body and in the longitudinal direction of the rail body. Since the wiring conductors are arranged along the wiring rails, the wiring rails can be freely bent and installed without the resistance of the wiring conductors being aligned with the wiring rails.

And a base formed of a material.

  By making the base portion of the rail body relatively rigid, the wiring rail is prevented from bending in directions other than the direction in which it can be bent.

  A relatively low rigidity of the electrode part of the rail body makes it possible to easily arrange a pair of conductors. For example, when a pinch type connector is connected to the electrode part, the connector In addition to being pressure-bonded to the conductor, it is possible to slightly bite into the electrode portion in the vicinity of the conductor, thereby improving the reliability of electrical connection.

  Also, when installing the base of the rail body on the upper side and the electrode part on the lower side, the base can be bent in the horizontal direction, which is the direction in which the wiring rail can be bent, by making the base relatively rigid. In this range, the wiring rail is prevented from being bent so as to hang downward, which is a direction other than the horizontal direction in which the wiring rail can be bent. Therefore, two or more types of rail body configurations can be formed, the upper base can be provided with a drooping prevention function, and the lower electrode can be provided with a function for improving workability and electrical contact reliability. It becomes.

  The wiring rail according to claim 3 is the wiring rail according to claim 1 or 2, wherein the pair of conductors of the rail main body has a polarity of a DC power source.

  A DC power source is supplied to the pair of conductors, and either a positive or negative arrangement of the DC power source may be used.

  The pair of conductors of the rail main body has the polarity of a DC power source, and is suitable for an application for connecting a lighting fixture using, for example, an LED. Can be omitted.

  A wiring device according to claim 4 is a wiring rail according to any one of claims 1 to 3; a connector that is detachably attached to the wiring rail and is electrically connected to a pair of conductors in an attached state; And a lighting fixture that is supported and electrically connected by the connector.

  As the connector, for example, a sandwiching type in which the rail body is sandwiched and attached is used, and the connector is electrically connected to the pair of conductors simultaneously with the attachment.

  A lighting fixture is supported via a cable, a rod, etc. with respect to a connector, for example, and light sources, such as LED, are used.

  And a connector is connected to the arbitrary position of the wiring rail which can be bent and installed freely, and it becomes possible to supply power by supporting the lighting fixture by this connector.

  According to the wiring rail according to claim 1, the rail body is formed to be bendable, and a pair of conductors intersects the bendable direction of the rail body on the side surface of the rail body in the bendable direction. Since the conductors are arranged along the longitudinal direction of the rail body, the wiring rails can be freely bent and installed without causing resistance to the bending of the wiring rails. The structure of the conductor can be simplified.

  According to the wiring rail according to claim 2, in addition to the effect of the wiring rail according to claim 1, the rigidity of the base portion of the rail body is made relatively high, and the wiring rail is bent in a direction other than the direction in which the wiring rail can be bent. In addition, the rigidity of the electrode part of the rail body can be made relatively low, and a pair of conductors can be easily arranged. For example, when a pinch type connector is connected to the electrode part, the connector However, it is possible to slightly bite into the electrode portion in the vicinity of the conductor and to improve the reliability of electrical connection.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a wiring rail and a connector, and FIG. 2 is a perspective view of a lighting device using the wiring rail.

  In the figure, the lighting device 11 is detachable at any position of the wiring rail 12 installed on the ceiling surface as the installation surface on the mounting member side, the fixture 13 for attaching the wiring rail 12 to the ceiling surface, and the wiring rail 12 And a lighting fixture 15 that is supported via the connector 14 and that receives power.

  The wiring rail 12 has a rail body 18 formed in a long shape, and a pair of conductors 19 are provided along the longitudinal direction of the rail body 18.

  The rail body 18 is formed in a substantially L-shaped cross section in a direction intersecting the longitudinal direction, that is, an attachment portion 20 is formed on one side to be attached in parallel to face the ceiling surface, and on the other side. A support portion 21 extending downward, which is a direction protruding vertically from the ceiling surface, is formed. A stopper portion 22 that protrudes from both side surfaces of the support portion 21 is formed at the distal end portion of the support portion 21.

  More specifically, the rail body 18 includes a member of the base 23 provided in a substantially L-shaped cross section from the mounting portion 20 to the middle of the support portion 21, and a member of the electrode portion 24 provided on the distal end side of the support portion 21. These two members are integrally formed. The base part 23 and the electrode part 24 are formed of a resin material such as soft vinyl chloride resin having flexibility and insulation that can be bent, but the base part 23 is formed of a material having higher rigidity than the electrode part 24, The electrode part 24 is made of a relatively soft material having a lower rigidity than the base part 23.

  The rail body 18 has a small horizontal cross-sectional width parallel to the ceiling surface, and a large vertical cross-sectional width that protrudes perpendicularly from the ceiling surface with respect to the horizontal width. Therefore, it is configured so that it is easy to bend in the horizontal direction and difficult to bend in the vertical direction with respect to the longitudinal direction of the wiring rail 12.

  The pair of conductors 19 are arranged on one side surface of the electrode portion 24 on the side from which the mounting portion 20 of the wiring rail 12 protrudes, in the vertical direction, which is a direction intersecting the longitudinal direction of the rail body 18 and the bendable direction. The rails 18 are provided along the longitudinal direction of the rail body 18 so as to be spaced apart and aligned in parallel. The pair of conductors 19 is composed of, for example, a single wire conductor such as a copper wire, and is embedded or fitted in a state where at least a part is exposed from the electrode portion 24.

  One side surface of the electrode portion 24 of the wiring rail 12 is located approximately in the middle of the rail body 18 in the width direction, that is, when the rail body 18 bends in the horizontal direction, which is a bendable direction, the inner circumference that receives a compressive load. The pair of conductors 19 are positioned at a substantially middle position between the side and the outer peripheral side receiving the tensile load.

  Further, the fixture 13 is made of, for example, plastic or metal, and can be disposed at an arbitrary position in the longitudinal direction of the wiring rail 12, and an engagement base 27 that is engaged with the upper surface of the mounting portion 20 of the rail body 18. One end engaging portion 28 that is bent into a substantially U shape from one end of the engagement base portion 27 and engages with the lower surface of the mounting portion 20 of the rail body 18, and is bent into a substantially L shape from the other end of the engagement base portion 27. The other end engaging portion 29 that engages with the other side surface of the rail body 18 is formed. An attachment screw 30 for screwing the attachment 13 to the ceiling surface is inserted through the distal end side of the one end engaging portion 28.

  Further, the connector 14 employs a pinching type in which the support portion 21 of the wiring rail 12 is pinched from both sides to mechanically lock and can be electrically connected. In other words, a pair of connection members 33 is provided, and an intermediate portion of the pair of connection members 33 is coupled to be rotatable about the shaft 34.

  At one end of the pair of connection members 33, a clamping part 35 is extended, and a clamping member 36 is attached to the tip of the clamping part 35 so as to be in contact with both side surfaces of the support part 21 of the wiring rail 12. . The clamping member 36 is formed with a clamping surface 37 that is in contact with the side surface of the support portion 21, and the clamping surface 37 is formed in an uneven shape in the vertical direction. The vertical width of the clamping member 36 is substantially equivalent to the width between the mounting portion 20 and the stopper portion 22, and the clamping member 36 is clamped by applying the tip of one clamping member 36 to the mounting portion 20. The position of the support portion 21 can be determined.

  At the other end of the pair of connecting members 33, operation portions 38 are respectively extended. By operating the operation portions 38 so as to hold the operation portions 38, the distance between the pair of holding portions 35 is reduced, and the support portions 21 of the wiring rails 12 are supported. Pinch.

  Although not shown, the connector 14 includes a ratchet mechanism that locks at a position where the gap between the pair of sandwiching portions 35 is narrowed so that the support portion 21 of the wiring rail 12 is sandwiched. A release button is provided that allows the gap between the pair of sandwiching portions 35 to be released to increase.

  A pair of terminals 39 that are in contact with the pair of conductors 19 are disposed on the sandwiching surface 37 of one of the sandwiching members 36, and wirings 40 respectively connected to the pair of terminals 39 pass through the connection member 33 to each operation unit. Guided from 38 tips.

  The lighting fixture 15 includes a lamp body 44 that uses an LED 43 as a light source. The lamp body 44 is suspended by a cord 45 that is a covered electric wire, and the upper end of the cord 45 is connected to each operation of the connector 14. It is connected to the portion 38 and is electrically connected to the wiring 40. A cylindrical cover 46 that covers the connector 14 in a detachable manner is inserted through the cord 45.

  Next, when constructing the lighting device 11, a plurality of fixtures 13 are arranged at predetermined intervals in the longitudinal direction of the wiring rail 12, and the wiring rail 12 is arranged according to the situation such as the area where the lighting fixture 15 is arranged. Is placed on the ceiling surface in a straight line state, or the wiring rail 12 is bent in the horizontal direction and placed on the ceiling surface, and the mounting screws 30 of the respective fixtures 13 are screwed onto the ceiling surface, and the wiring rail 12 is placed on the ceiling surface. Install. The pair of conductors 19 of the wiring rail 12 located at the end is connected to a power supply unit (not shown).

  The connector 14 that supports the lighting fixture 15 is attached to an arbitrary position in the longitudinal direction of the wiring rail 12 according to the place where the lighting fixture 15 is arranged.

  That is, with the gap between the pair of clamping members 36 of the connector 14 open, the clamping members 36 are arranged at positions facing both side surfaces of the support portion 21 of the wiring rail 12, and the pair of operating portions of the connector 14 are operated. By operating so as to grip 38, the gap between the pair of holding portions 35 is narrowed to hold the support portion 21 of the wiring rail 12, and this holding state is locked by the ratchet mechanism. In this clamping state, the convex part of the clamping surface 37 provided in a concavo-convex shape in the vertical direction of the clamping member 36 slightly bites into the relatively soft electrode part 24 of the support part 21, and the lower part of the clamping member 36 enters the stopper part 22. The connector 14 can be reliably restricted from being displaced downward relative to the wiring rail 12 by being engaged.

  At this time, the vertical width of the sandwiching member 36 is substantially equivalent to the width between the mounting portion 20 and the stopper portion 22, and the tip of one sandwiching member 36 is brought into contact with the mounting portion 20 so that the sandwiching member 36 It is possible to accurately position the support portion 21 to be sandwiched. Therefore, the pair of terminals 39 provided on one clamping member 36 can be brought into electrical contact with the pair of conductors 19 automatically and reliably.

  Thereafter, the cover 46 is raised to cover the connector 14.

  Then, by supplying direct current power from a power supply unit (not shown) to the pair of conductors 19 of the wiring rail 12, the pair of conductors 19 supplies power to the LED 43 through the terminal 39, the wiring 40 and the cord 45 of the connector 14, and the LED 43 Lights up.

  Further, when removing the luminaire 15, the cover 46 is lowered to expose the connector 14, and the holding member 36 of the connector 14 is released by pressing the release button of the connector 14 to release the holding state. The distance between the wiring rail 12 and the wiring rail 12 is released.

  In this way, the rail body 18 of the wiring rail 12 is formed to be bendable, and a pair of conductors 19 intersect the bendable direction of the rail body 18 on one side of the rail body 18 in the bendable direction. The wiring rails 12 can be freely bent and installed without causing resistance to the bending of the wiring rails 12 due to the arrangement of the conductors 19 along the longitudinal direction of the rail body 18. Therefore, the structure of the pair of conductors 19 can be simplified.

  Further, the rail body 18 is composed of two members, that is, an upper base portion 23 having a mounting portion 20 and not provided with a pair of conductors 19 and a lower electrode portion 24 provided with a pair of conductors 19. The base portion 23 has a relatively high rigidity, and the electrode portion 24 has a relatively low rigidity. The horizontal direction in which the wiring rail 12 can be bent while the wiring rail 12 can be bent in the horizontal direction, which is the direction in which the wiring rail 12 can be bent, by making the rigidity of the base 23 relatively high. It can suppress that it bends so that it may hang down below which is a direction other than. On the other hand, since the rigidity of the electrode portion 24 is relatively low, the pair of conductors 19 can be easily disposed as compared with the case where the rigidity of the electrode portion 24 is too high. When connected to the portion 24, the pair of terminals 39 of the connector 14 are crimped to the pair of conductors 19, and the convex portion of the clamping surface 37 of the connector 14 slightly bites into the electrode portion 24 near the conductor 19. Thus, the reliability of the electrical connection can be improved. Therefore, two or more types of configurations of the rail body 18 can be formed, and the upper portion can be provided with a droop prevention function, and the lower portion can be provided with a function of improving workability and reliability of electrical contact.

  In addition, one side surface of the electrode portion 24 of the wiring rail 12 is positioned approximately in the middle of the rail body 18 in the width direction, that is, receives a compressive load when the rail body 18 is bent in the horizontal direction, which is a bendable direction. Since the pair of conductors 19 is located in the substantially middle position between the inner circumference side and the outer circumference side receiving the tensile load, a large displacement force is not applied to the conductor 19, A single wire conductor such as a copper wire can be used.

  In addition, the pair of conductors 19 of the rail body 18 has the polarity of a DC power supply, and is suitable for the application of connecting the lighting fixture 15 using the LED 43. In such an application, the voltage is low and the cover that covers the conductor 19 etc. Can be omitted.

  In addition, although the example which attaches the wiring rail 12 to a ceiling surface as an installation surface was shown, you may attach to a wall surface as an installation surface.

  Further, the connector 14 may be provided in a separate configuration without using both the mechanical holding and the electrical contact portion.

It is a perspective view of the wiring rail and connector which show one embodiment of this invention. It is a perspective view of the illuminating device using a wiring rail same as the above.
