Claims

[Scope of Claim for Utility Model Registration] (1) In a lighting fixture equipped with a removable cover at the bottom of the fixture body, a supporting piece at the upper end and a swinging piece at the lower end are connected by a narrow connecting piece. A swinging locking plate having a hook is formed on the outer surface of the swinging piece, and the swinging locking plate is attached to the lower part of the instrument main body through the support piece with the hook facing outward. The device is suspended and supported so as to be able to swing freely inward and outward directions, and a coil spring is installed between the device body and the device body, located around the connecting piece of the device. The cover body is provided with a locking portion that is locked by the hook of the swing locking plate, and the cover body is urged inward to push the swing piece of the swing locking plate. 1. A cover attachment/detachment device for a lighting fixture, characterized in that a movable unlocking body is provided that can be pushed and operated. (2) A hole with an inner diameter slightly larger than the width of the connecting piece is formed in the part of the device body that supports the rocking locking plate, and the rocking lock plate is formed at the inner and outer edges of this hole. 2. A cover attachment/detachment device for a lighting fixture according to claim (1), characterized in that a notch is formed into which a support piece of a locking plate is inserted. (3) Practical use characterized in that locking portions for locking support pieces of the swing locking plate are formed on both sides of the hole formed in the portion of the device body that supports the swing locking plate. A cover attachment/detachment device for a lighting fixture as set forth in claim (2) of patent registration.
