Description

[Detailed description of the invention] The present invention is a recessed switch or outlet box that can be used in two rooms, more specifically, a two-room switch or outlet box that is useful when installing switches or outlet boxes in two adjacent rooms across a wall. It relates to a shared recessed switch or outlet box.

Conventionally, recessed switches or outlet boxes are installed in each room and fixed at the desired location by attaching them to wall base material such as rafters, but when installing them at the same location in two adjacent rooms across a wall, In housing complexes such as apartments, the walls are relatively thin (usually 4 to 5 cm), so two boxes are usually installed, for example, on either side of the rafters or shifted up and down so as not to overlap each other.

The present invention is particularly intended to simplify the installation of switches or outlet boxes at approximately the same position in two adjacent rooms across a wall in such thin-walled multi-room buildings. The two opening surfaces of the resin square frame 1 are each vertically divided into two halves, and the opposite halves of the two are provided with an opening 2 for attaching a cover plate.
2′, and the other half is the same synthetic resin plate 3 as the frame,
The openings 2 and 2' are provided with protrusions 4, 5 and 4', 5' each having a screw hole for attaching the cover plate, and are formed on one side of the frame 1. To provide a recessed switch or outlet box for shared use in two rooms, which is provided with means for attaching to rafters.

Although the screw-hole internal protrusions 4, 5, 4', and 5' are shown as being integrated with the synthetic resin walls 3 and 3', they are integrated with the top and bottom surfaces of the frame 1, respectively. or may take any other known format. Furthermore, it goes without saying that the means for attaching the rafters are not limited to those illustrated, but may be of any known type. Reference numerals 7, 8, 9, etc. are wiring notch holes, which, as is known, are provided at any desired location. Furthermore, if necessary, a boundary plate can be inserted to divide the box into two chambers.

Since the present invention is constructed as described above, it is only necessary to install one box in two adjacent rooms separated by a wall, which conventionally required two separate boxes. Conventional 1/
2 or less. In addition, by using the box of this invention, you can make the necessary branches within the box by just wiring one electric wire, which is necessary when installing two boxes in close proximity as in the past. Another advantage is that it eliminates the need for crossover wiring.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention.
2 is a perspective view of the box, FIG. 2 is a rear perspective view, and FIG. 3 is a sectional view taken along line A--A in FIG. 1. 1 is a corner frame, 3 and 3' are plate walls that form a box integrally with the corner frame, and 2 and 2' are openings for attaching a cover plate.

Claims (1)

[Scope of utility model registration request] The two opening surfaces of the synthetic resin square frame 1 are each vertically divided into two halves, the opposite halves of which are used as the openings 2 and 2' for attaching the lid plate, and the other half is made of the same synthetic resin plate 3 as the frame. The openings 2 and 2' are provided with protrusions 4, 5 and 4', 5' each having a screw hole for attaching the cover plate, and are formed on one side of the frame 1. A recessed switch or outlet box for common use in two rooms, which is provided with means 6 for attaching to rafters.
