[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device mounting plate metal fitting which is screwed and fixed to a wall surface for mounting the device on the wall surface.

[0002]

[Prior art]

 FIG. 5 is a front perspective view showing a conventional example of a device mounting plate metal fitting, and FIG. 6 is a view showing an intermediate process when the device mounting plate metal fitting is screwed and fixed to a wall surface.

The conventional device mounting plate metal fitting 1 is designed to be screwed and fixed to the wall surface, and by interlocking a device (not shown) such as an intercom with the four locking claws 3, Equipment can be attached. Reference numeral 4 denotes an engaging piece that is engaged with the edge of the device. By fixing the engaging piece 4 to the edge of the device with a screw, the device is removed from the plate fitting 1 for mounting the device. This is to prevent it from coming off easily. Further, the device mounting plate metal fitting 1 is provided with screw holes 2 in the vicinity of each of the four corners thereof, and is screwed and fixed to the wall surface in each of the screw holes 2.

[0004]

[Problems to be solved by the device]

 However, in the conventional device mounting plate metal fitting 1, in a state where it is temporarily fixed to the wall surface by hand in accordance with the virtual horizontal line C shown in FIG. 6, first, at one screw hole 2, a screw 7 is used to screw it to the wall surface. Then, if the user releases the device mounting plate fitting 1 in that state, the device mounting plate fitting 1 tilts around the screw 7 as shown in FIG. Since it would be displaced, it was necessary to re-fix it to the original temporary fixing position again, which hindered the installation on the wall.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a device mounting plate metal fitting which can be temporarily fixed to a wall surface during installation and construction. To do.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-described problems, and the present invention is a device mounting plate metal fitting that is screwed and fixed to a wall surface, wherein the wall surface is screwed at least at two different screw holes. A device mounting plate tool that is fixedly fixed includes a protrusion that presses against the wall surface when the screw hole is fixed to the wall surface at one screw hole. .

[0007]

[Action]

 When the device mounting plate metal fitting of the present invention is first screw-fastened to the wall surface in one screw hole, the projection comes into pressure contact with the wall surface, and the concentrated load is applied to the contact portion between the projection and the wall surface. Causes the temporary fixing to the wall without manually fixing it to the wall.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The parts corresponding to those of the conventional example are designated by the same reference numerals as those of the conventional example.

FIG. 2 is a rear perspective view showing a device mounting plate metal fitting of the first embodiment according to the present invention. Further, FIG. 1 is a view showing an intermediate step in mounting the device mounting plate fitting on a wall surface and is a sectional view taken along the line AA of FIG. However, in FIG. 1, for convenience of drawing, a part of the vicinity of the center of the device mounting plate fitting 1 is cut away.

As shown in FIG. 2, the device mounting plate fitting 1 according to the first embodiment of the present invention is provided with a projecting piece 5 attached to each of the four screw holes 2. The projecting piece 5 is formed by being cut and raised so as to project to the rear of the device mounting plate fitting 1, and has a certain degree of elasticity. In addition, the cut-out mark of the projecting piece 5 remains as the cut-out hole 8. The other parts are the same as in the above-mentioned conventional example, and the description thereof will be omitted.

The device mounting plate metal fitting 1 having the above-described structure is temporarily fixed to the wall surface by hand, and is first screwed to the wall surface by the screw 7 in one screw hole 2 as shown in FIG. The projecting piece 5 near the screw 7 is fitted into the cut-out hole 8 cut out by itself while the corners thereof are cut into the wall surface. Further, the projecting piece 5 near the screw hole 2 other than the screw hole 2 fixed by screwing is pressed against the wall surface while biting the corner portion thereof into the wall surface. In that state, a concentrated load acts on the contact portion between the corner portion of the projecting piece 5 and the wall surface, and the concentrated load is due to the elasticity of the projecting piece 5 and the bending stress of the device mounting plate metal fitting 1 itself. Has been obtained by. Therefore, the projecting piece 5 temporarily fixes the device mounting plate tool 1 to the wall surface. Also, in the above description, the case where the wall surface is made of a relatively soft material is shown. However, when the wall surface is made of a hard material, the projecting piece 5 does not bite into the wall surface by the screwing, and is strongly pressed against the wall surface. The protruding piece 5 is fitted into the cut out hole 8.

FIG. 4 is a rear perspective view showing a device mounting plate metal fitting according to a second embodiment of the present invention. Further, FIG. 3 is a view showing an intermediate process when the device mounting plate fitting is mounted on a wall surface and is a sectional view taken along line BB in FIG. However, in FIG. 3, for convenience of drawing, a part of the vicinity of the center of the device mounting plate metal fitting 1 is cut away and shown.

As shown in FIG. 4, a device mounting plate fitting 1 according to a second embodiment of the present invention has a projection 6 formed in a substantially conical shape so as to be attached to each of the four screw holes 2. Is provided. The projection 6 is provided so as to project to the rear of the device mounting plate fitting 1. The other parts are the same as those in the conventional example, and the description thereof is omitted.

The device mounting plate metal fitting 1 having the above-described structure is temporarily fixed to the wall surface by hand, and is first screwed to the wall surface by the screw 7 in one screw hole 2 as shown in FIG. The projection 6 near the screw 7 digs into the wall surface and sinks, and the projections 6 near the screw holes 2 other than the screw holes 2 fixed by screwing press the tip thereof against the wall surface. In this state, a concentrated load acts on the contact portion between the tip of the projection 6 and the wall surface, and the concentrated load is obtained by the bending stress of the device mounting plate metal fitting 1 itself. The device mounting plate fitting 1 is temporarily fixed to the wall surface by the projection 6. After that, when the other screw hole 2 is screwed to the wall surface, the projection 6 attached to the screw hole 2 bites into the wall surface and sinks. In the device mounting plate fitting 1, the projection 6 digs into the wall surface and immerses into the wall surface regardless of the hardness of the wall surface to be screwed and fixed.

In the present invention, it is sufficient to provide at least one of the projecting piece 5 or the projecting piece 6. For example, even if only one projecting piece 5 or projection 6 is provided in association with a certain specific screw hole 2 and screws are fixed from the screw holes 2 other than the specific screw hole 2, Is temporarily fixed to. Further, as in the embodiment of the present invention, if the projecting piece 5 or the projecting piece 6 is provided in the vicinity of each screw hole 2, the screw is fixed from any screw hole 2 while temporarily fixing it to the wall surface. It can be fixed.

[0016]

[Effect of device]

 According to the first and second aspects of the present invention configured as described above, temporary fixing to the wall surface can be performed without temporary fixing to the wall surface, and installation on the wall surface becomes very easy.
