Board for distributing implement

The present invention relates to a board for a wiring tool, which is installed in a buried hole in a building surface such as a wall surface for installing the wiring tool.

There has been conventionally provided a plate for wiring tool, in which an embedded box (switch box) is embedded in an embedded hole provided in a construction surface such as a wall surface, a plate frame having an installation portion to which a switch, a plug, and other wiring tools are detachably installed integrally or separately is installed on the embedded box from the front side of the embedded hole, a center plate is installed on the front side of the plate frame, and a decorative metal plate is installed on the front side of the center plate, thereby embedding the wiring tool in the wall surface or the like in a beautiful manner.

However, in the above-described conventional technique, since the metal plate is fixed to the center plate by using a double-sided tape, there is a problem that the work efficiency is poor in the manufacturing process.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a plate for a wiring tool, in which a metal plate can be easily attached to a center plate and the work efficiency can be improved in the manufacturing process.

In order to achieve the purpose, the invention adopts the following technical scheme:

the board for wiring tool is characterized by comprising: a plate frame integrally or separately provided with a mounting part to which an embedded wiring tool can be mounted, and covering an opening surface side of an embedded hole provided in a construction surface; an upper center plate which has an opening part for exposing the functional surface of the wiring device and is arranged on the front surface of the plate frame; and a metal plate having an exposure window for exposing the functional surface of the wiring tool and covering the front surface of the front center plate; the metal plate is provided with one or more locking parts, and the central plate is provided with one or more locked parts which are engaged with the locking parts in a concave-convex manner. The engagement part provided on the metal plate is engaged with the engaged part on the center plate, so that the metal plate of the center plate can be easily attached without using a double-sided tape, and the work efficiency of the attachment work of the metal plate and the center plate can be improved in the manufacturing process.

The plate for a wiring tool is characterized by comprising: a plate frame; integrally or separately provided with a mounting part for mounting an embedded wiring tool, and covering the opening surface side of an embedded hole provided on a construction surface; a center plate having an opening portion for exposing the functional surface of the wiring device and mounted on the front surface of the plate frame; and a metal plate having an exposure window for exposing the functional surface of the wiring device and covering the front surface of the center plate; the metal plate is provided with a riveting part riveted on the central plate. The metal plate can be easily attached to the center plate without using a double-sided tape by caulking the caulking portion provided on the metal plate to the center plate, and the work efficiency of the attachment work of the metal plate to the center plate can be improved in the manufacturing process.

In the board for wiring tool: the back side of the central plate is provided with a locking projection, the front side of the plate frame is provided with a locking hole locked by the locking projection, and the central plate is provided with a notch part for inserting a tool for dismounting the locking projection and the locking hole. The jig is inserted into the notch portion, and the center plate and the metal plate are lifted by the lever principle, so that the engagement between the engaging protrusion and the engaging hole is released, and the center plate and the metal plate can be easily detached from the plate frame.

In the plate for a wiring tool, a claw not protruding from the notch is provided at a position corresponding to the notch on the plate frame. The jig inserted into the notch portion is in contact with the claw, so that when the central plate and the metal plate are detached from the plate frame, the jig can prevent the construction surface from being scratched.

In the plate for a wiring tool, a screw insertion hole through which a fixing screw for mounting the plate frame on a building surface is inserted is provided on a freely stretchable mounting sheet which is supported on the plate frame so as to be freely bendable. Thus, even if the counterpart fastened by the screw (for example, a mounting frame to which a wiring tool is attached) has a claw protruding from the building surface or a notch portion. The jig inserted into the notch portion is in contact with the claw, so that when the central plate and the metal plate are detached from the plate frame, the jig can be prevented from abutting on the building surface to cause a flaw.

In the plate for a wiring tool, a screw insertion hole through which a fixing screw for setting the plate frame on a building surface is inserted is provided on a freely stretchable mounting sheet which is supported on the plate frame in a freely bendable manner. Thus, even if the object to be screwed by the screw (for example, the mounting frame to which the wiring device is attached) is raised or recessed with respect to the construction surface, the offset due to the raised or recessed portion is absorbed by the bending of the mounting piece, and the gap between the plate light and the construction surface is prevented.

The invention has the following effects:

The following examples illustrate the invention in detail:

embodiment 1

Embodiment 1 will be described below with reference to fig. 1, 2, 3, and 4. The board for wiring tool of the present invention is composed of a plate frame 1, a center plate 20 and a metal plate 30.

The plate frame 1 is formed by integrating a vertical piece 2 made of an insulating synthetic resin (thermoplastic resin such as ABS or thermosetting resin having elasticity), a horizontal piece 3 shorter than the vertical piece, and a mounting piece 4 having a screw insertion hole 4a through which a mounting screw 80 for mounting the plate frame 1 to the mounting frame 40 is inserted and having a freely stretchable shape into a rectangular frame shape, and an opening 5 for exposing a functional surface of the switch 50 mounted to the mounting frame 40 to the front side is formed in the center portion.

On the other hand, the mounting frame 40 is made of a metal material and formed in a rectangular frame shape having a mounting window 41 at the center, and both side pieces 42 facing each other in the longitudinal direction are provided with an elongated hole 43 through which a mounting box screw for mounting a mounting box can be inserted, an insertion through hole 44 through which a screw for mounting a construction surface directly attached to a wall surface is inserted, a metal gasket locking hole 45 for fitting a metal gasket used in mounting a wall plate or the like shaped as a construction surface, and a screw hole 46 screwed to the mounting screw 80. Fitting claws 48a, 48b that are fitted into frame body fitting holes 53 provided on both side surfaces of a boss 52 of the switch 50 are provided on side pieces 47a, 47b that sandwich the mounting window 41 and oppose each other in the longitudinal direction. One side frame piece 47b supports the engaging claw 48b from both sides by a supporting piece 49 having an extremely small width. That is, when the switch 50 is mounted on the mounting frame 40, the fitting claws 48a of the side frame pieces 47 are first fitted into the housing mounting holes 53 of the switch 50, and the insertion claw 48 is fitted into the housing mounting hole 53 of the switch 50 by pressing and bending the support piece 49 of the other side frame piece 47b toward the end of the mounting window 41 using a tool such as a screwdriver, thereby mounting the switch 50 on the mounting frame 40. In addition, 3 sets of engaging claws 48a and 48b are provided in the mounting frame 40 so that 3 switches 50 can be mounted in parallel in a direction perpendicular to the longitudinal direction. The mounting frame may be made of synthetic resin, not limited to metal, and in the case of synthetic resin, a locking hole for locking the protruding fitting claw 55 is provided on the side surface of the assembly frame 54 of the switch 50.

The panel frame 1 is mounted on the front surface of the mounting frame 40 to which the switch 50 is mounted as described above. That is, the mounting screws 80 are inserted through the screw insertion holes 4a provided in the mounting pieces 4 of the panel frame 1, and the panel frame 1 is screwed and fixed to the mounting frame 40 by screwing the mounting screws 80 into the screw holes 46 provided in the side pieces 42 of the mounting frame 40. Even if the mounting frame 40 is mounted on the embedded box, even if the mounting frame is warped or dented with respect to the construction surface, the mounting screw 80 is tightened and the mounting piece 4 in the freely stretchable state is bent, so that the displacement due to the warping or dented can be absorbed, and as a result, the gap between the floor light and the construction surface can be prevented.

Further, the center plate locking holes 6 to be fitted with the locking projections 25 projecting from the rear surface of the body portion 21 of the center plate 20 are provided at the four corners of the plate frame 1, and the center plate 20 is detachably attached to the front surface side of the plate frame 1 by inserting the locking projections 25 into the center locking holes 6. Further, a tapered surface 6a inclined from the front side to the back side is formed on the inner side surface of the center plate locking hole 6, and the locking projection 25 can easily perform the locking operation through the guide of the tapered surface 6 a.

On the other hand, the center plate 20 is made of an insulating synthetic resin (thermoplastic resin such as ABS or thermosetting resin having elasticity) in the same manner as the plate frame 1, and is formed in a substantially box shape by integrally forming a rectangular main body portion 21 covering the front surface of the plate frame 1 and a side wall 23 projecting from the entire peripheral edge of the main body portion 21 to the back surface side. The locking projections 25 are provided so as to protrude from four corners of the rear surface side of the body. An opening 22 for exposing an operating knob 51 of a switch 50 attached to the attachment frame 40 is provided in the body portion substantially at the center. Here, since the width dimension between the side walls 23 opposed to the center plate 20 is wider than the respective width dimensions of the panel frame 1, when the center plate 20 is attached to the front side of the panel frame 1 provided on the building surface after being attached to the attachment frame 40, the panel frame 1 is drawn toward the side walls 23 of the center plate, and the front end edges of the side walls 23 are almost brought into contact with the building surface. As a result, as in the conventional art, the projection joining surfaces of the panel frame 1 and the center panel 20 do not protrude further than the building surface, and the projection joining line therebetween is visually hardly visible from the side surface, which is a good appearance.

The side wall 23 of the center plate 20 is provided with an inclined surface 23a inclined from the edge in contact with the building surface toward the main body 21, and a plurality of restricting ribs 26 which are in contact with each other in the direction along the building surface and restrict the movement of the center plate 20 are provided on the side surfaces of the panel frame 1. That is, when the center plate 20 is attached to the front side of the plate frame 1, the restricting rib 26 comes into contact with the side surface of the plate frame 1, and vibration in the direction along the building surface of the center plate 20 with respect to the plate frame 1 can be prevented.

On the other hand, the panel frame 1 is provided with a stretch portion 7 which stretches continuously and outwardly over the entire peripheral edge of the panel frame 1. A plurality of rib frames 27 for preventing the vibration of the central plate 20 are provided along the inner side surfaces of the side walls 23 on the front surface of the extension part 7. Therefore, when the center panel 20 is mounted to the panel frame 1, the rib frame 27 is mounted on the front surface of the extension portion 7 of the panel frame 1, and vibration of the center panel 20 in a direction substantially perpendicular to the building surface can be prevented.

A pair of recesses 24 are provided in the side walls 23 facing each other in the longitudinal direction of the center plate, and the center plate 20 can be detached from the plate frame 1 by releasing the engagement between the locking projections 25 of the center plate 20 and the center plate locking holes 26 of the plate frame 1 by inserting jigs into the notches 24 and biasing the center plate 20 toward the front side. Here, the claws 8, which are thinner than the thickness of the expanded portion 7, are extended to such an extent that they do not protrude from the notch portions 24 of the center plate 20 at positions corresponding to the notch portions 24 of the vertical pieces 2 of the panel frame 1. That is, although there is a concern that the jig inserted into the notch portion 24 may damage the building surface by biasing the portion contacting the building surface as a fulcrum, the jig inserted into the notch portion 24 may contact the claws 8 by providing the claws 8 as described above, and damage to the building surface due to the jig can be prevented when the center plate 20 is removed from the plate frame 1.

However, the front surface of the center panel 20 is provided with a metal plate 30 for decorative or design beauty and for improving fire resistance. The metal plate 30 is formed with an exposure window 31 (corresponding to one module size) that exposes a functional surface of one switch 50 at a substantially center position as shown in fig. 2, and is provided with a side surface portion 30a that is curved in a substantially arc shape toward the back surface side along the longitudinal direction. On both side surface portions 30a opposed to each other in the short width direction of the metal plate 30, 4 mounting pieces 32 are vertically provided on the back surface side thereof at approximately equal intervals, and a projecting engaging portion 33 is formed on the inner surface of each mounting piece 32. As shown in fig. 3, the locking portion 33 has a tapered surface 33a formed inside and inclined in the direction away from the tip of the side surface 30 a.

On the other hand, a fitting recess (not shown) for fitting the metal plate 30 is formed on the front surface side of the center plate 20, and insertion grooves 28 into which the tip portions of both side surface portions 30a of the metal plate 30 are inserted are formed in both side walls 23. As shown in fig. 2, a notch 21a for avoiding the attachment piece 32 is provided on both side walls 23 of the metal plate 30 at a position corresponding to each attachment piece 32, and a flexible fitting piece 29 that is fitted to the locking portion 33 of the metal plate 30 in a concave-convex manner is integrated near the tip of the notch 21 a.

Then, as shown in fig. 3 and 4, the tip portions of the side surface portions 30a of the metal plate 30 are inserted into the insertion grooves 28 formed in the side walls 23 of the center plate, and the attachment pieces 32 of the metal plate 30 are inserted into the notch portions 21. At this time, the tapered surface 33a of the locking portion 33 provided on the inner surface of the mounting piece 32 is fitted to the fitting piece 29, and the fitting piece 29 receiving the pressing force from the locking portion 33 is bent as the mounting piece 32 is pressed in, and then the tip of the fitting piece 29 and the locking portion 33 of the mounting piece 32 are fitted to each other in a concave-convex manner as shown in fig. 3, and the metal plate 30 is fitted to the fitting recess on the front surface of the center plate 20 and fixed (prevented from coming off) by the concave-convex fitting between the locking portion 3 and the fitting piece 29.

As described above, since the metal plate 30 can be easily attached to the center plate 20, the work efficiency of the work of attaching the metal plate 30 to the center plate 20 can be improved in the manufacturing process.

However, the number, shape, and size of the opening 22 of the center plate 20 and the exposure window 31 of the metal plate 30 vary depending on the type and number of wiring tools to be mounted on the mounting frame 40. For example, when the switches 50 or the wiring devices 2 having the same size are mounted on the mounting frame 40, the openings 22 and the exposure windows 31 having the same size may be arranged and mounted in the longitudinal direction.

When the switches 50 are attached to the mounting frame 40 in 3 pieces, or when wiring devices having a size of 3 pieces in total of the switches 50 are attached to the mounting frame 40, the openings 22 and the exposure windows 31 may be arranged in 3 pieces. Further, only the single module size may be set to an appropriate value (for example, japanese industrial standard high angle connector wiring tool (JISC8304), etc.), and only the wiring tool suitable for the size can be commonly mounted on the mounting frame 40. In the present embodiment, the mounting portion to which the wiring harness (switch 50) can be detachably mounted is divided into the panel frame 1 and the mounting frame 40, but the mounting frame 40 may be integrated with the panel frame 1, for example.

In the present embodiment, a rib-shaped caulking portion 34 is provided to protrude from both side surface portions 30a of the metal plate 30 in place of the attachment piece 32 in the embodiment, and the metal plate 30 is attached and fixed to the center plate 20 by caulking such caulking portion 34 to the center plate 20.

The caulking portions 34 are provided at approximately equal intervals on the opposite side surface portions 30a of the metal plate 30 facing each other in the short width direction, and are provided at positions corresponding to the positions where the mounting pieces 32 are provided in the embodiment. Then, as shown in fig. 5, the tip portions of the side surface portions 30a of the metal plate 30 are inserted into the insertion grooves 28 formed in the side walls 23 of the center plate, and the caulking portions 34 of the metal plate 30 are inserted into the notch portions 21. Then, by caulking the caulking portion 34 from the back surface side of the center plate 20, the metal plate 30 is fitted into the fitting recess on the front surface of the center plate 20 and is caulked and fixed by the caulking portion 34 as shown in fig. 6.
