Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a device for holding electric equipment such as electric fans, remote control switches, interphones, etc. on walls, etc.

(b) Prior Art Figures 1 to 3 show the conventional structure of a holding device for holding onto the wall of a control box that controls a wall-mounted electric fan. A wall-mounted electric fan 3 consisting of a stand 1 and a fan main body 2 is attached to a wall W using a conventionally known structure. The electric fan 3 is controlled by a control box 5 attached to the lower end of an electric cord 4 drawn out from the lower end of the stand 1 along the wall W and wired. The control box 5 consists of a front case 6 and a rear case 7 molded from synthetic resin. The front case 6
and the rear case 7 are joined by a screw 9 screwed into a boss 8 protruding inside the front case 6. The electrical cord 4 is drawn into the control box 5 through an insertion portion formed at the central joint portion of the upper surface of the front case 6 and rear case 7. The electric cord 4 is wound around the boss 8 and held there. An insertion hole 12 through which the head 11 of the screw 10 fixed to the wall W is inserted, and a locking hole 13 continuous with the insertion hole 12 are formed in the upper center of the rear surface of the rear case 7.
The locking hole 13 and the electric cord 4 are opposed to each other. Therefore, if the amount of protrusion of the screw 10 from the wall surface W is large, the electric cord 4 would be damaged by the head 11 of the screw 10.

In addition, although the purpose of the invention was different, the structure was considered to prevent electrical cords from being damaged.
There is a case holding device described in Japanese Patent No. 57-4442. The holding device has an extending piece of an elastic body having a protrusion extending from the screw receiving portion and facing the elongated hole of the combination hole of a round hole and an elongated hole, and the protrusion extends from the screw head. It is configured so that it is pressed and held by coming into contact with it. Therefore, the extending piece can bend to some extent due to the pressure of the screw head, but there is a limit to this, and if the screw head is large, it cannot be installed, and the size is also limited by the molding, so it cannot provide sufficient protection. It was hot.

(c) Purpose of the invention The purpose of this invention is to provide a holding device that has a simple structure and can reliably protect electrical cords.

(d) Structure of the invention The invention consists of an insertion hole through which the head of a screw screwed into a wall or the like is inserted, and a locking hole continuous with the insertion hole, on the rear surface of an electrical equipment frame to which an electrical cord is wired. A partitioning rib is formed on the frame body to surround both sides of the locking hole, and a head of the screw is formed on the edge of the partitioning rib so as to cover the locking hole. The structure is such that a bendable protective piece is interposed between the electrical cords.

(e) Embodiment The present invention will be explained based on the embodiment shown in FIGS. 4 to 9.

The control box 20 includes a front case 21 and a rear case 22 molded from synthetic resin. A circular recess 24 to which a name plate 23 is attached is formed in the center of the front surface of the front case 21, and a through hole 26 in which a switch 25 is mounted is formed in the center of the recess 24. The front case 2
1 has an arcuate rib 27 surrounding substantially the upper half of the switch 25, a plurality of pin-like protrusions 28 and a plurality of boss-like protrusions 29 protruding from the lower half of the switch 25, A boss 31 is formed into which a screw 30 for fixing the rear case 22 is screwed. The boss 31 is formed on the inside opposite to a notch 32 formed in the upper part of the arcuate rib 27. A locking protrusion 33 is formed on the lower inner surface of the front case 21, and an electric cord insertion notch 34 is formed on the upper edge.
is formed. A pair of pins 35 are provided protruding from the inner edge of the notch 34 . An electrical cord 36 connected to the switch 25 is inserted between the protrusions 28 and connected to the rib 27 from the outside of the protrusion 29.
The notch 3 of the rib 27 is wired along the outside of the rib 27.
After being pulled inward from 2 and wrapped around the boss 31 in a U-shape, it is pulled out again through the notch 32 and out of the front case 21 through the notch 34. The electrical cord 36 is twisted between the notch 32 and the notch 34.

A locking piece 37 that engages with the locking protrusion 33 is provided on the lower edge of the rear case 22, and a cutout 38 that matches the cutout 34 is formed on the upper edge of the rear case 22. There is. The cutout portion 34 and the cutout portion 38 form an insertion portion for the electrical cord 36. A recessed engagement portion 39 with which the pin 35 engages is formed on the inner surface of the notch 38 . The front case 21 and the rear case 22 connect the locking piece 37 to the locking protrusion 3.
3, and by engaging the pin 35 with the engaging portion 39, a matching contact is made. The rear case 22
An insertion hole 4 that abuts the boss 31 is provided at the upper center of the
A screw receiving portion 41 having a diameter of 0 is formed. By inserting the screw 30 through the insertion hole 40 and screwing it into the boss 31 and fixing the screw receiving part 41 to the boss 31, the front case 21 and the rear case 2
2 are combined. The screw receiving portion 41 is formed at the bottom of a cylindrical recess 43 in the rear surface of the rear case 21 into which the head 42 of the screw 30 is inserted. The inner upper half side of the recess 43 is cut out, and a partition rib 44 extending upward from the inner side of the recess 43 is formed at the upper inner side of the rear case 22 . The opening of the recess 43 and the notch form an insertion hole through which the head 46 of the screw 45 screwed into the wall W is inserted. On the rear surface of the rear case 22, there is an elongated locking hole 4 that is continuous with the opening of the recess 43.
7 is formed. Both sides of the locking hole 47 are surrounded by the partition ribs 44. Said partition rib 44
A bendable protection piece 48 is formed on the edge of the cover. During molding, the protective piece 48 is formed as an extension of the partition rib 44 as shown in FIG. 8, and when joining the rear case 22 to the front case 21,
It is constructed between the partition ribs 44 and the locking hole 47
It is bent to cover the Therefore, the electrical cord 36 and the locking hole 47 and recess 43 portion where the head 46 of the screw 45 is located are separated, so that the head 46 of the screw 45 comes into contact with the electrical cord 36. It won't hurt you. Further, the protective piece 48 is bendable, so that the screw 45
Even if the head 46 of the electric cord 36 is large, the electric cord 36 will not be damaged by simply pushing the protective piece 48 inward. A protrusion 4 is provided on the inner surface of the rear case 22.
9, and the protrusion 49 is connected to the front case 2.
By engaging with the protrusion 29 of 1, the front case 2
1 and the rear case 22 are joined and reinforced, and the electrical cord 36 can be held securely.

(f) Effect of the invention This invention prevents damage to the electrical cord by covering the head of the screw with a bendable protective piece, and provides safety even if there are slight changes in the screw and the amount of screwing. Moreover, it has the effect of being able to be held stably.
