Abstract

PURPOSE: To prevent damage to a wall panel in terms of ages caused by insertion and removal of a plug by forming a support for fixing a wiring apparatus with a surrounding overlap part fitted to almost all a mounting opening edge, and fixing the support and a panel holding member with a screw passing through the mounting opening. CONSTITUTION: A support 2 and a panel holding metallic member 3 have each screw hole 5a or 5b linked through a mounting opening 1, and each overlap part 2b or 3b to be fitted to an opening edge of the mounting opening 1 around the four edges thereof. The support 2 and the panel holding member 3 are mounted to hold a wall panel (P) in between when a screw passing through a mounting opening 1 is screwed through the screw holes 5a and 5b. Here, the overlap part 3b of the panel holding member 3 is fitted to the opening edge of the mounting opening 1, and thereby, for example, the tension load caused by pulling out a plug from an outlet can be dispersed through the overlap part 3b to the wall panel (P).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device mounting structure in a boxless construction method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, as a construction method for attaching a wiring device such as an outlet to a wall panel,
A boxless construction method is widely known in which a wall panel is sandwiched between a support 20 to which a wiring device is attached and a panel pressing metal fitting 30 through an opening 10 formed in the wall panel, and both 20 and 30 are fixed with screws 40. ing. According to this boxless construction method, wiring equipment installation work can be performed consistently after the completion of construction work, so that the installation work can be made more efficient.

[0003]

By the way, in the actual use of the wiring device, for example, in the case of an outlet, the plug is frequently inserted and removed. However, according to the above-mentioned conventional mounting structure, the panel holding metal fitting 30 is Since the entire periphery is in contact with the peripheral edge of the opening 10, the tensile load caused by pulling out the plug is applied to the contact surface with the opening 10, and the influence on the wall panel is small. On the other hand, the support 20 has only the upper and lower ends fixed to the opening edge of the opening 10 with screws 40, and there is a gap between the left and right ends of the support 20 and the opening 10. Therefore, the pushing load at the time of inserting the plug is concentrated near the screw stop with the opening 10. Moreover, since the load applied at the time of insertion is larger than that at the time of pulling out the plug, there is a problem that the wall panel is damaged over time due to repeated plug removal and insertion in the vicinity of the screw stop. Moreover, it is troublesome to partially reinforce only the vicinity of the screw of the support 20 at the opening edge of the wall panel 10, and the cost is increased accordingly.

The present invention has been made in view of the above conventional problems, and while keeping the advantages of the conventional boxless construction method, it is possible to prevent the wall panel from being damaged over time due to the simple construction of the plug. An object of the present invention is to provide a mounting structure for a wiring device in the boxless construction method to be obtained.

[0005]

In order to achieve the above object, the present invention provides a wall with a support for fixing a wiring device and a panel pressing metal fitting through a mounting hole for the wiring device formed on a wall panel. In the wiring device mounting structure that sandwiches the panel, the support is formed with a superposed portion that abuts almost the entire opening edge of the mounting opening at the periphery of the support, and the support and the panel holding metal fitting are screwed through the mounting opening. It is a fixed configuration. Further, the overlapping portion of the support may extend to the vicinity of the peripheral edge of the decorative plate.

[0006]

According to the present invention which employs the above means, the overlapping portion of the support frictionally abuts the opening edge of the mounting opening, so that the pushing load applied to the wiring device due to the insertion of the plug or the like can be prevented. It is widely dispersible through the wall panel. Also, the larger the area of this contact surface, the better the load distribution, but the extent to which the overlapping portion of the support is extended depends on the size of the decorative plate that covers the support.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a mounting structure according to this embodiment. In the figure, 1 is a mounting opening formed in a part of the wall panel P, 2 is a support arranged on the indoor side, and 3 is a panel pressing metal member that faces the support 2 via the wall panel P. The components are the same as the members used in the conventional boxless method. A decorative plate 4 is for covering the support 2 exposed in the room, and can be selected according to the type of wiring equipment to be attached and the interior.

Openings 2a and 3a and screw holes 5a and 5b are formed in the support 2 and the panel holding metal fitting 3 at positions communicating with the mounting opening 1, and the mounting openings are formed at the four peripheral edges of the two and three. The overlapping portion 2 that comes into contact with the opening edge of 1
b * 3b is formed. In addition, a screw hole 6 for screwing the decorative plate 4 is provided in the upper and lower overlapping portion 2b of the support 2. The support 2 mainly functions as a mounting frame for the wiring device and fixes the wiring device in the opening 2a. However, since the opening 2a can adopt a conventionally known structure, here, the wiring device is used. A specific description of the fixing means will be omitted.

As shown in FIG. 2, the support 2 and the panel pressing metal member 3 having the above-described structure hold a wall panel P by screwing a screw 7 communicating with the mounting opening 1 into the screw holes 5a and 5b. It has been fixed to. At this time, since the overlapping portion 3b of the panel pressing metal fitting 3 is in contact with the opening edge of the mounting opening 1, the outlet C will be described as an example of the wiring device.
The tensile load applied when pulling out the plug (not shown) from the outlet C can be distributed to the wall panel P via the overlapping portion 3b.

Further, as shown in FIG. 3, since the overlapping portion 2b of the support 2 is also configured to abut the opening edge of the mounting opening 1, the pushing load applied when inserting the plug is overlapped. It can be dispersed over the entire part 2b.
At this time, the larger the overlapping portion 2b and the larger the area in contact with the opening edge of the mounting opening 1, the more efficiently the pressing load can be dispersed, but the support 2 is completely covered by the decorative plate 4. Since it is essential that the size of the overlapping portion 2b is determined by the size of the decorative plate 4. For this reason, the overlapping portion 2b of the support 2 is
It is preferable to extend to the vicinity of the peripheral edge of the decorative plate 4 used. As described above, according to the present embodiment, the load applied to the wiring device is dispersed by the overlapping portions 2b and 3b, so that it is possible to prevent damage to the wall panel P due to repeated insertion and removal of the plug.

In the above embodiment, the mounting structure using one support of three modules has been described, but this does not limit the number of wiring devices to be mounted. When installing more wiring devices, there are cases where a plurality of supports are connected and cases where the size (area) of the supports themselves is expanded. At this time as well, it is necessary to distribute the pushing load applied to the wiring equipment to the wall panel. Therefore, in the former case, for example, when two supports are laterally connected, a support in which overlapping portions are formed on the remaining three sides is used except for one side where both supports are in close contact. That is, in this case, the pushing load can be dispersed by connecting the supports having the overlapping portions formed on either one of the upper and lower sides and the left and right sides. On the other hand, due to the expanded support,
It is necessary to widen the mounting opening of the wall panel according to the expansion of the opening, but regarding the formation of the overlapping portion of the support, it may be formed so that the four peripheral edges thereof contact the opening edge of the mounting opening. It can be performed in the same manner as Support 2 of. Here, it is important for both of them to use a panel pressing metal fitting or a decorative plate suitable for the form of the support.

On the other hand, regarding the attachment of the decorative plate 4, in this embodiment, the screw hole 6 formed in the support 2 is made to project toward the decorative plate 4, and further, the screw having a length which does not reach the wall panel P when screwed. The decorative board 4 is fixed by using. Although this mounting means is known, it is preferable because the wall panel P is not perforated.

[0014]

As described above, according to the present invention, since the support has the overlapping portion that abuts almost the entire opening edge of the mounting opening, even if a pushing load is applied to the wiring device by inserting a plug or the like, This load could be distributed to the wall panel, and damage to the wall panel over time could be prevented. Moreover, in claim 2, since the overlapping portion of the support is up to the vicinity of the peripheral edge of the decorative plate, the overlapping portion is not exposed to the interior of the room by sticking out the decorative plate. Could be dispersed on the wall panels.
