Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a device mounting device for mounting a clock, an intercom, or the like of the present invention to a mounting surface such as a wall.

(Prior Art) For example, there is a device shown in Japanese Utility Model Publication No. 44-7947, in which a device main body is attached via a mounting plate that is conventionally attached to a mounting surface.

In this device, the mounting plate is provided with two bulges, and the bottom plate of the device is provided with two tongue pieces that engage with the bulges. Further, a receiving piece is provided on the mounting plate, and the equipment is supported by this receiving piece, and the equipment is screwed using this receiving piece.

Also used as a protective frame mounting device for ventilation fans.
There is one shown in Publication No. 41-23428.

This device has an inserter with a dogleg-shaped cross section spaced from side to side on the inside of the upper part of the rectangular cylindrical frame, and a through hole into which the tightening screw is inserted approximately in the center of the lower part. A convex plate with screw holes is provided,
On the other hand, the outer casing to which this frame is attached is provided with a convex plate into which the insertion hole is inserted, and an L-shaped plate with a cutout into which the tightening screw is installed. It is something.

(Problems to be Solved by the Invention) In the former case, when the device is attached to the mounting plate, the tongue and the bulge cannot be clearly seen, and furthermore, the two tongues provided on the bottom plate of the device are attached to the mounting plate. Since it is necessary to drop and engage the two bulges, even if one tongue piece engages with the bulge part, the other tongue piece may not engage with the bulge part. It has the disadvantage that it is difficult to install.

In addition, in the latter case, the two inserters are bent in a dogleg shape, so after passing the L-shaped plate through the convex plate of the frame, the inserter is inserted into the outer casing. It cannot be inserted into a convex plate. For this reason, it is necessary to insert the two inserters so as to drop them into the convex plate at the top of the outer casing, and then pass the L-shaped plate through the convex plate of the frame. Also, since the inserter and the convex plate are located at the back of this one, they cannot be seen clearly, and like the former, there are two parts that must be engaged at the same time by dropping.
It has the disadvantage that it is difficult to install.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a device mounting device for equipment that has a simple structure and can be easily mounted and fixed.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a mounting plate that is attached to a mounting surface and a box-shaped device that is attached to this mounting plate. Either the mounting plate or the bottom plate of the device has a large-diameter hole and a small-diameter hole that communicates with one side of the large-diameter hole, each of which faces in the same direction. A plurality of engagement holes are provided. Similarly, on the other hand, corresponding to the engagement hole, each tip part is sized so that it can be inserted into the large diameter hole of the engagement hole, but cannot be inserted through the small diameter hole, and an intermediate part is formed. A plurality of protrusions are provided that can be inserted through the small diameter hole of the engagement hole. Further, a projecting piece having a screw hole and projecting toward the device side is formed at one end of the mounting plate. On the other hand, a positioning guide hole is formed at one end of the bottom plate of the device, through which the protrusion can be inserted, and through which the device can be moved within a predetermined range with respect to the inserted protrusion. Also, a through hole is formed in the side plate near the guide hole so as to face the screw hole of the protrusion inserted through the guide hole. The screw is inserted from the through-hole side and screwed into the screw hole of the protrusion to fix the mounting plate and the device, and the protrusion is inserted into the guide hole and the protrusion is guided. By abutting one end of the hole, the tip of each of the protrusions is inserted into the corresponding large diameter hole of each of the engagement holes, and then by shifting the device, each of the protrusions is inserted into each of the engagement holes. The structure is characterized in that the mounting plate and the device are fixed by being locked in a small diameter hole and by screwing the screw into the screw hole from the through-hole side.

(Function) With the above configuration, the protrusion is inserted into the guide hole while pressing the device against the mounting plate,
By abutting one end of the guide hole, the tip of the projection can be inserted into the large diameter hole of the engagement hole. In other words, when inserting the protrusion into the guide hole, there is no need for complicated operations such as dropping the protrusion as in the prior art described above, and it is sufficient to simply press the protrusion against the guide hole. When inserting the projecting piece into the guide hole, the through hole can also be used as a mark.

After inserting the protrusion into the large-diameter hole of the engagement hole, by shifting the device relative to the protrusion, each of the protrusions is locked into the small-diameter hole of each of the engagement holes, and
The through hole and the screw hole are close to each other.

By screwing the screw into the screw hole from the through-hole side, the mounting plate and the device are fixed.

In this way, by devising the locations and shapes of the protrusions, guide holes, and through holes for fixing the mounting plate and equipment, the structure can be made more complex without increasing the number of special parts. The installation work can be simplified without any trouble.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1 is a mounting plate, and 2 is a box-shaped device, such as a watch, which is attached to this mounting plate. The mounting plate 1 in this embodiment has both sides bent at different levels and a recess 3 provided in the center. A plurality of protrusions 4 each having a large diameter tip are provided on both sides. On the other hand, the bottom plate of the device 2 is provided with a plurality of, for example, four, engagement holes 5 for engaging the projections. The engagement hole 5 includes a large-diameter hole through which the tip of the projection 4 can be inserted, and a small-diameter hole that communicates with one side of the large-diameter hole through which the tip of the projection 4 cannot be inserted. It has a section. In this embodiment, the hole has a so-called potbellied hole shape. And these engagement holes 5
are provided so that the respective large diameter holes and small diameter holes are positioned in the same direction (the small diameter holes face upward in FIG. 1). Reference numeral 6 denotes an inverted T-shaped protrusion provided at one end of the mounting plate 1 and having a screw hole 7 in the center. A positioning guide hole 8 is formed at one end of the bottom plate of the device 2, through which the protrusion 6 can be inserted, and through which the device 2 can be moved within a predetermined range with respect to the inserted protrusion 6. . In addition, a through hole 9 is provided on the side surface of the device 2 near the guide hole 8 so as to face the screw hole 7 of the projecting piece 6 inserted through the guide hole 8 . In addition, 10 is a comb tooth-shaped stopper piece provided at the lower end of the recess 3 to prevent the cord from falling when the cord etc. is stored in the recess 3 of the mounting plate 1, and 11 and 12 are stopper pieces for equipment and mounting, respectively. This is a cord insertion hole provided in the board.

Next, the mounting method of this embodiment will be explained with reference to FIGS. 2A to 2D. After the mounting plate 1 is mounted on the mounting surface by a well-known means, the tip of the protruding piece 6 is inserted through the guide hole 8 of the bottom plate of the device 2, as shown in FIG. At that time, a through hole 9 is provided in the side plate near the guide hole 8, and this through hole 9 is formed by a projecting piece 8 that is inserted into the guide hole 8.
Since it is provided so as to face the screw hole 7 of the guide hole 7, if the device 2 is pressed against the protrusion 6 using the through hole 9 as a mark, the protrusion 6 can be smoothly inserted into the guide hole 8. . As shown in FIG. 4B, the guide hole 8 is fitted into the protrusion 6 until it contacts the shoulder of the protrusion 6, and at the same time, the protrusion 6 is brought into contact with the lower end of the guide hole 8. As a result, the device 2 is positioned with respect to the mounting plate 1, and the tip of the protrusion 4 is inserted through the large diameter hole of the engagement hole 5. Then, by shifting the device 2 downward until the protruding piece 6 hits the upper end of the guide hole 8, the protrusion 4 is locked in the engagement hole 5, as shown in FIG. Next, as shown in FIG. 2D, the device 2 is fixed to the mounting plate 1 with screws 11 inserted through the through hole 9 and the screw hole 7 of the protrusion 6 to prevent it from falling. It should be noted that when the front side of the device 2 is open, it will be easily understood that by looking into the guide hole, the operation of inserting the protrusion into the guide hole can be performed more easily.

Note that the protrusion 4 and the engagement hole 5 may be provided in the device 2 in the former and in the mounting plate 1 in the latter. Further, the positions of the protruding piece 6, the guide hole 8, and the through hole 9 may be not only at the upper end of the mounting plate 1 and the device 2, but also at the lower end or the lateral end.

[Effects of the Invention] As detailed above, the present invention provides a protrusion having a screw hole at one end of the mounting plate, and a protrusion opposite to the protrusion at one end of the bottom plate of the device. A guide hole is provided for positioning through which the protrusion can be inserted, and a through hole is provided in the side plate near the guide hole to face the screw hole of the protrusion inserted through the guide hole. The projecting piece can be inserted into the guide hole by simply pressing it against the guide hole. After this or at the same time, by bringing the protrusion into contact with one end of the guide hole, the tip of the protrusion becomes able to be inserted into the large diameter hole of the engagement hole. After inserting the tip of the protrusion into the hole, by shifting the device, the protrusion can be locked in the small diameter hole of the engagement hole. Thereafter, fixing is performed using the screw hole of the protrusion for positioning. In this way, since the protruding piece, guide hole, and through hole are used to mount the device, the work of attaching and fixing the device to the mounting plate is as simple as described above, without using special positioning members. It can be easily done with just one.
