Description

[Detailed Description of the Invention] This invention relates to a cord holding device in which a lighting lamp is suspended by the cord itself.

Instead of the conventional lighting fixtures in which the lighting fixtures are hung with hanging metal fittings, chains, etc., the type of hanging with cords has the advantage that parts such as hanging metal fittings and chains are unnecessary, and there is no need for complicated installation. On the other hand, there was a risk that the cord itself would be subject to the tension of the illuminating light, causing the installation position to shift and the cord to break.

Therefore, this invention was devised in view of the above-mentioned drawbacks of the conventional art.The top part of the stop plate bent into a chevron shape is fixed to the shaft horizontally suspended inside the mounting cover body, and the top part of the stop plate is fixed to the shaft astride the sloped parts on both sides. A plurality of locking holes are arranged in a row, and both ends of the cord are bent and inserted through the locking holes adjacent to each other, and the tension of the cord is applied to the ends of the upper and lower surfaces of both locking holes. The object of the present invention is to provide a device that can reliably prevent the cord from moving and breakage of the cord by locking at the edge, and can further improve the workability of the attachment part.

An embodiment of the configuration of this invention shown in the drawings will be described in detail below.

Reference numeral 1 denotes an attachment cover body, which is composed of a shallow bowl-shaped outer peripheral cover 2 and a bowl-shaped central cover 4 rotatably attached to a circular hole 3 opening at the center thereof. Reference numeral 5 denotes a mounting bracket, which includes an upper plate portion 6 that contacts the ceiling A, side plate portions 7 bent downward on both sides thereof, and leg portions 8 whose lower ends are bent outward. The upper plate part 6 has a cord hole 9 in the center through which the cord B can be inserted, and a mounting hole 11 and a keyhole-shaped slide hole 12 for attaching to the ceiling A with screws 10 are provided on both sides. to drill. A shaft insertion hole 13 that opens on the side is bored in the side plate portion 7 in order to attach a shaft 22 to be described later.
A screw hole 15 into which the shaft set screw 14 is screwed, and a cut and raised stopper piece 16 for the shaft set screw 14 are provided above it. Further, a screw hole 17 is provided in the leg portion 8, and a screw 19 is inserted into a hole 18 formed in the outer circumferential cover 2 to fix the mounting bracket 5 and the outer circumferential cover 2. 20 is a cord holding device, which consists of a stop plate 21 and a shaft 22;
The stop plate 21 is formed by folding a rectangular metal plate in half in the longitudinal direction to form a chevron shape, and the top part of the stop plate straddles the shaft 22 and is fixed by welding or screws, and the slope parts 23, 23 on both sides are fixed. A total of eight locking holes 24, four in one row, are bored in each of the holes. This shaft 22 is inserted into shaft holes 25 bored on both upper sides of the center cover 4, and further inserted into the shaft insertion hole 13 of the mounting bracket 5, and the shaft set screw 14 is screwed into the screw hole 15. Accordingly, the head 14a of the shaft set screw 14 engages with the shaft 22, and locks the shaft 22 so that it does not come off from the shaft insertion hole 13. 26 is a cord that connects the stop plate 21 to two adjacent locking holes 24, 2.
4, and one end passes through a pipe-shaped arm 27 attached to the center cover 4 and is pulled out downward, and a lighting lamp C is connected and suspended from the lower end portion. The other end is connected to a wiring cord B pulled out from the ceiling A.

With this structure, in order to assemble this, insert the shaft 22 into the shaft hole 25, incorporate the cord holding device 20 into the center cover 4, and then insert the cord holding device 20 into the center cover 4, and then insert the Since the locking hole 24 is a four-lamp type in the case of the embodiment, the locking holes 24, 24 of both slope portions 23, 23, respectively.
Bend the cord 26 through the
7 and the other end is the wiring code B.
Leave the core wire sticking out for connection. On the other hand, the mounting bracket 5 was attached to a predetermined position on the ceiling A with screws 10, the shaft 22 of the cord holding device 20 was inserted into the shaft insertion hole 13 of the mounting bracket 5, and the shaft 22 was attached with the shaft set screw 14. After that, connect the wiring cord B and the core wire of the cord 26, and finally connect the outer cover 2 and the mounting bracket 5 with the screw 1.
9 to complete the assembly.

In the case of the embodiment, a four-light type is used, but the present invention is not limited to this, and the cords may be inserted into adjacent locking holes as appropriate depending on the number of lights.

In such a state, when the weight of the illumination lamp etc. is added to the cord, tension acts on the cord, and the cord is pulled downward, the cord 26 bent and inserted through the locking hole 24 of the slope portion 23 of the stop plate 21 will be inserted into the locking hole. 24 upper and lower both edges 2
4a, 24b and the bent portion of the cord 26 (see FIG. 4), the cord 26 is held securely without shifting.

As described above in detail with respect to the embodiments, this invention suspends the lighting lamp using the cord itself, so there is no need for special hanging parts such as hanging hardware or chains, and the installation work is less complicated. can be resolved. In addition, the cord retaining device that holds the cord is constructed by fixing a retaining plate bent in a chevron shape to the shaft, so it has an extremely compact structure, and is particularly suitable for use in a narrow mounting cover body with a low height. Can be stored and easily installed. Furthermore, it can be freely adapted to the number of illumination lights to be attached, has high versatility, and can simplify manufacturing and assembly. Furthermore, the cord attached to the retaining plate is retained by the frictional force between the edge portions of both upper and lower sides of the inclined retaining hole and the bent portion of the cord, so the cord is attached to one retainer. It will be locked to the locking hole at two locking parts, so even if it is subjected to tension such as the weight of the hanging lighting lamp, external force, or swinging of the center cover, it will not pass through the two locking holes. There will be no need to move without permission. On the other hand, when adjusting the length of the cord, you can easily and freely adjust the movement by slightly loosening the part that connects to the stop plate, and the length of the cord that connects to the wiring cord can be adjusted by slightly loosening the part that connects to the stop plate. Since no tension is applied to the cord by the stopping portion, various excellent effects are produced, such as being able to prevent failures such as wire breakage.
