である。FIG. 5 shows a conventional cover fall prevention device disclosed in Japanese Utility Model Application Publication No. 59-5812, in which 1 is a T-bar having a flat part 1bt at the lower end of the vertical part 1a and a protruding part 1c at the upper end; 4 is a transparent cover placed between the flat parts lb of two T-bars 1 fixed in parallel, and 4 is a transparent cover 8.
The main body 4b extends upward from the mounting part 4a and abuts the T-bar 1 to elastically hold the translucent cover 8 between the T-bars 1. This is a stopper consisting of a locking part 4c provided at the upper end of the main body 4b so as to come into contact with the protruding part 1c of the T-bar 1 when it moves upward. Note that 13 is a fluorescent lamp, and 14 is a reflector.

が多くなシ加工費もかさむ等の問題があった。However, in the conventional device described above, the stopper 4 for preventing the transparent cover 8 from falling is located at the end t of the transparent cover 8.
- Since it is simply inserted by dropping it in, the fixation is unstable, and the stopper 4 may come off when it is inserted, and the transparent cover 4 may break due to excessive stress. Another method to ensure secure fixation is to drill a small hole in the translucent cover 8 and caulk it, but this method has problems such as a large number of parts and high processing costs.
本発明は上記のような問題点を除去するために成された

ある。In the fall prevention device according to the present invention, a leaf spring is curved and attached between the protruding part and the flat part of the T-bar, and one end of the leaf spring is made a part of the free end, and the curved part on the free end side is used as the fixed end side. The curved portion) is made to protrude inward, and a translucent cover is sandwiched between the flat portion of the T-bar and the curved portion of the leaf spring.

きる。The translucent cover can be installed easily and without any problems (by using the deformation of the leaf spring to push it in). Further, the cover can be securely fixed due to the elastic action of the leaf spring.
以下、本発明の実施例を図面とともに説明する。 Embodiments of the present invention will be described below with reference to the drawings.

来と同様である。In FIGS. 1 to 4, 15 is a protrusion 1c of the T-bar 1.
A leaf spring curved inwardly and held between the flat part 1b and the flat part 1b.
A slit 10 is provided from the lower part of the leaf spring 15 toward the upper end, and one of the lower ends divided by the slit 10 is shortened to form a free end 11, and this free end 11 side is also curved to form the inclined part 6 and the abdomen 7. The abdomen 7 is made to protrude inward from the curved portion 5 on the fixed end 12 side. Other configurations are the same as before.

圧され、確実に挾持される。In the above configuration, when attaching the transparent cover 8,
First, as shown in FIG. 1, insert one end 9 of the translucent cover 8 into contact with the protruding part 1c of the T-bar 1, and then push up the other end 9' in the direction of arrow A to mount the T-bar 1. Dodge the flat part 1b. Next, when the free end 11 side of the leaf spring 15 is pushed apart with the end portion 9' and the transparent cover 8 is shifted to the one end 9' side, the one end 9 of the transparent cover 8 is moved to the abdomen 7 of the leaf spring 15. Slide down the slope 6 to a slightly higher position. In the state shown in FIG. 2, when one end 9 is pushed up in the direction of arrow B and this pushing up force is released all at once, one end 9/fi passes over the abdomen 7vi- due to its own weight and stops at the flat part 1b of the T-bar 1. In this way, as shown in FIG.
, 9' are pressed horizontally and vertically in a well-balanced manner between the flat portion 1b of the T-bar 1 and the curved portion including the abdomen 7 of the leaf spring 15, and are securely held.

生じない。As described above, according to the present invention, both ends of the translucent cover are pressed horizontally and vertically in a well-balanced manner using the elasticity of the leaf springs, thereby preventing cracks in the translucent cover or detachment of the leaf springs. The translucent cover can be securely fixed without any hindrance. Furthermore, since the translucent cover is not subjected to drilling or caulking, processing costs and the number of parts can be reduced. Further, in a small room, the light-transmitting cover does not move up and down due to wind pressure caused by opening and closing the door, causing rattling noises, and of course, the light-transmitting cover does not fall due to misalignment.
