Description

[Detailed description of the invention] This invention relates to the invention of an electrical equipment mounting mechanism using a wall laminate, which uses a thin wall laminate to mount a series unit for television reception, etc., and has standard specifications. It is an object of the present invention to provide a mechanism that can be easily and stably attached to an electric equipment fixing plate according to the present invention without any special processing.

When installing electrical equipment such as a serial unit for television reception, a switch, or an outlet on a wall, the electrical equipment is housed in an iron box of standard dimensions (commonly known as an outlet box) buried in the wall layer. That is, in the conventional general method of attaching electrical equipment to the fixing plate attached to the iron box, the thickness of the wall layer is sufficient to completely bury the iron box. However, with the recent development and spread of building technology, especially new products related to building materials, the thickness of partition walls has become thinner so that they cannot be embedded in such iron boxes. . Therefore, as a method of attaching electrical equipment such as the above-mentioned series unit to a partition wall made thin in this way, a clamping member is attached to each end of the fixing plate on which the electrical equipment is attached in a pivoted state. , a screw inserted into the fastening plate is screwed into the screw hole formed in this clamping metal fitting, and by tightening the screw, a wall plate is formed between the end of the fastening plate and the clamping metal fitting. It is done by inserting and installing. That is, the mechanism proposed as such is as shown in FIGS. 1 and 2, in which a fastening plate 11 having a width sufficient to accommodate the electrical equipment 10 has a fastening plate 11 on both sides of the narrow part 11a. The scissors 13 are arranged oppositely with the notches 12.
The proximal hook portion 14 of the holder is pivotally locked (rotatable as shown in FIG. 2), and the insertion hole 15 formed on the end side of the fastening plate 11 The screw 16 inserted into the fixing plate 11 (originally for fastening the fixing plate 11 to the iron box) is screwed into the screw hole 17 in the middle of the clamping fitting 13. As shown in the solid line state in the figure, a wall laminate 20 is interposed between the end of the fastening plate 11 and the tip of the clamp 13 (specifically, a third (with the edge of the opening formed as shown in the figure intervening), and in this state, tighten the screw 16 to move the tip of the clamp 13 from the state shown by the imaginary line in FIG. 2 to the state shown by the solid line. is drawn to the back surface of the fastening plate 11, and the wall laminate board 20 is clamped and fixed from the inside and outside. The plate 21 is attached with screws 19 inserted into the screw holes 18 of the narrow portion 11a, and examples of such a structure include Japanese Utility Model Application No. 51-85605.
By the way, it is clear that this product has the advantage of being able to be mounted directly to the wall board without the need for an iron box according to the JIS standard, but as mentioned above, it is not possible to install it with a clamp when it is designed to be installed on an iron box. Fixing plate 11 for installation with metal fittings
Further, it is necessary to form the above-mentioned locking notches 12, 12 on both sides of the narrow portion 11a. Also, an opening 2 formed in the wall laminate 20
3 is preferably as small as possible, it is preferable to make the angle of inclination of the clamp 13, which is inclined with respect to the fastening plate 11, as large as possible as shown by the solid line in FIG. This is why it is possible to insert this clamp 13 into the small opening 23, and in order to increase the angle of inclination of the clamp 13, the insertion hole 15 is simply made into a horizontally elongated hole. However, it is not sufficient to insert a screw 1 into the center of the insertion hole 15 as shown in FIG.
Since the relief portion 16a of No. 6 must be modified into a cut T-shaped hole, there is a disadvantage that the processing cost increases. If the opposed notches 12 and 12 as described above are formed from the beginning, it is necessary to attach the notches 12 and 12 to the iron box and screw holes 1.
The narrow portion 1 is designed based on the premise of the necessary strength to form a portion 8 and attach the flash plate.
1a, and furthermore, since the screw 16 inserted into the insertion hole 15 is not screwed into a stable rigid body like an iron box, the strength of the screw hole 18 in the narrow portion 11a is reduced. When the screw is pushed in to attach the flash plate, if the pushing force becomes a little large, the fastening plate 11 will cut into this notch 1.
2 and 12, and the overall mounting dimensional relationship based on the fastening plate 11 fluctuates, making it impossible to ensure a stable mounting relationship. Disadvantages have been confirmed during actual installation work at each site. .

The present invention has been devised after repeated studies in view of the above-mentioned circumstances, and the embodiments shown in the attached drawings are as shown in Figure 3 and below. Using the fixing plate 11 of the equipment case to which the electrical equipment 10 is attached and the clamping metal fittings 13 are used for the opening 23 that has been opened, the above-mentioned wall layer board 20 is attached using the screws 16 screwed into the clamping metal fittings 13.
The fastening itself is the same as that shown in Figs. 1 and 2 described above, but in the present invention, the clamping fitting 13 has a feature as shown in Fig. 7.
The pivoting attachment structure to the fastening plate 11 side is such that extending portions 3, 3 are provided oppositely to the clamping metal fitting 13 formed in a flat plate shape with an interval corresponding to the width of the fastening plate 11. On the other hand, regarding the fastening plate 11, at least the insertion hole 15 portion is simply left as the insertion hole 15 is provided, and the extending portions 3, 3 are used as a cover for the electrical equipment 10 attached to the side wall portion of the fastening plate 11. It is inserted between bent protrusions 1 and 2 formed for assembling and fitting the parts. That is, in the case of such an electric device 10, a protrusion is provided on the circumferential side of one of the material plates of the main body cover portion, and during assembly, the protrusion is bent to hold the other material plate. In the case of the above-mentioned series unit, the fixing plate 11 itself is used as a side wall of the case main body, and the circumference provided on the case bottom plate, which is the cover part, is used as the side wall of the case main body. The side protrusions are bent to form equipment cases, and in any case, it is well known that such bent protrusions 1 and 2 are located on both sides of the bottom corner part. Since the bent protrusions 1 and 2 protrude from the side surface of the case by a height corresponding to the thickness of the material, such bent protrusions 1 and 2
The extending portions 3, 3 are inserted between the two on both sides of the device case, and furthermore, between these extending portions 3, 3 of the clamping metal fitting 13, there is a joint protrusion for the back surface of the fastening plate 11. 4 by bending it appropriately,
Further, reinforcing bent portions 3a are formed on both sides of the fastening plate 11 to provide reinforcement in the cross direction.

As shown in FIGS. 4 and 5, the clamping fitting 13 of the present invention is used to fasten the wall laminate by tightening the screw 16 using the joint protrusion 4 that contacts the back surface of the fastening plate 11 as a fulcrum. 20, the clamping fitting 13 is displaced within the range between the solid line and the imaginary line in Fig. 4,
Creates a safe and firm tightening condition.

As shown in FIG. 6, the screw hole 18 for attaching the flash plate has a screw hole portion 18a which is bent and protrudes in the thickness direction of the fastening plate 11 on the outside of the insertion hole 15. It is obvious that the same can be applied to a device in which a flash plate mounting screw is screwed into the screw hole 18 of the screw hole portion 18a. Further, in such a case, the clamping fitting 13 can be formed with the tip side enlarged into a fan shape.

According to the present invention as described above, it is possible to attach the device according to the normal standard specifications, and the bent protrusion 1, Since the extending parts 3, 3 of the clamping metal fitting 13 are connected between the two, it is possible to take a considerably large amount of relative movement in the length direction of the fastening plate 11 of the clamping metal fitting 13. Since the joint protrusion 4 acts as a fulcrum on the back surface of the fastening plate 11, it is not limited by the thickness of the wall laminate 20, and the opening 23 formed in the wall laminate 20 is relatively small. Even if
There is no need to form a notch 12 in the insertion hole 15 forming part as in conventional ones, and the clamping fitting is reinforced with a reinforcing bent part 3a and a bent joining protrusion 4, respectively. The strength as designed can be maintained, and since the joint protrusion 4 is connected to the back side of the fastening plate and acts as a fulcrum when fastening with the screw 16, the fastening at the tip of the clamping metal fitting is extremely strong. Moreover, it is stable and, of course, has the advantage of effectively preventing bending of the narrow part 11a due to the cut in the narrow part 11a when installing the flash plate as in the conventional one. Since the relative displacement of the screw 13 is large, there is no need to make the insertion hole 15 of the screw 16 a T-shaped hole, and there is no need for any special processing on the standard-produced fastening plate 11. Even in standard type equipment cases that are installed using iron boxes (outlet boxes), the clamping fittings of the present invention can be used as is, and this is a highly effective idea in practical terms. .
