DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The lighting fixture with accessories of FIGS. 1 to 5 includes a box-shaped fixture main body 10 having an open bottom surface. An accessory 20 such as a light-transmitting cover or a louver is provided so as to cover the lower surface opening of the device main body 10. An accessory frame 30 is provided around the accessory 20 and holds the accessory 20. It is formed by bending an elastic wire,
The two leg portions become fixed ends 42 and 43 attached to the accessory frame 30, and midway become free ends 44 and 45 extending toward the instrument body 10, between the fixed ends 42 and 43 and the free ends 44 and 45. Is provided with an elastic engaging member 40 having a pair of protruding portions 46 and 47 protruding so as to widen the interval. A pair of protruding portions 46 provided on the instrument body 10 are provided.
A receiving device 12 is provided which allows resilient passage with elastic deformation of 47 and engages and holds the vicinity of the protruding portions 46 and 47 from both ends at all times. The number of the elastic engaging members 40 and the number of the corresponding receiving members 12 are plural.
In the vicinity of one of the receiving members 12, a hook 14 for locking and holding the free ends 44 and 45 after the engagement by the receiving member 12 is released is provided. The hook 14 is not provided near the other receiver 12. 92 is a reflector, 94 is a lamp socket, and 96 is a straight tube fluorescent lamp. These are arranged inside the instrument body 10. The accessory 20 is arranged on these lower surfaces. Reference numeral 60 denotes a ceiling material, in which an embedding hole is formed at an appropriate place, and the device main body 10 is embedded therein.

The hook 14 shown is formed by cutting and raising a part of the receiving member 12 and integrally forming the receiving member 12. In this case, one of the receiving members 12 is a receiving member 12 with a hook 14 and the other is a receiving member 1 without a hook 14.
It becomes 2. The elastic engaging member 40 has a pair of free ends 44 and 45. This is to provide appropriate elasticity of an appropriate stroke between the pair of projecting portions 46 and 47. There is at least one set of the elastic engaging device 40 and the corresponding receiving device 12 with the hook 14, and at least one set of another elastic engaging device 40 and the corresponding receiving device 12 without the hook 14. . The number of the hooks 14 of the receiver 12 with the hook 14 is two, which corresponds to the number of the free ends 44 and 45. A procedure for attaching and detaching the accessory 20 will be described. Accessory 2
The accessory frame 30 is grasped with the “0” floating slightly. A force is applied to the accessory frame 30 to uniformly lower it. The resilient engagement between each receiving member 12 and the protruding portions 46 and 47 of each elastic engaging member 40 is thereby released one by one. There is no interaction between the catch 12 without the hook 14 and the corresponding elastic engaging member 40, and the elastic engaging member 40 slips downward. The interaction between the catch with hook 14 and the corresponding resilient engagement 40 remains.
The elastic engaging member 40 stops at the position where the free ends 44 and 45 are engaged with the hooking member 14, and the elastic engaging member 40 is stopped at that position. The result is as shown in FIG. FIG. 4 shows a state in which the hooks 14, the free ends 44 and 45, the elastic engaging members 40, and the accessory frame 30 are suspended, and the accessory frame 30 and the accessory 20 are inclined. Since there are two hooks 14 and two free ends 44 and 45 are suspended there, the stability is good. In this state, the fluorescent lamp 96 is replaced or the accessory 20 is replaced. The subsequent work is as follows.

The accessory frame 30 is held substantially horizontally.
The elastic engaging device 4 corresponding to the receiving device 12 without the hooking device 14
Align the free ends 44 and 45 of 0. The free end 44.4 of the corresponding elastic engaging member 40 is attached to the receiving member 12 with the hooking member 14.
Part of 5 has already been inserted. Under such circumstances, the accessory frame 30 is pushed up strongly. As a result, the protruding portions 46 and 47 of the elastic engaging members 40 resiliently engage with the receiving members 12. The disengagement between the hook 14 of the catch 12 with the hook 14 and the free ends 44 and 45 of the corresponding elastic engaging member 40 is not usually necessary,
If necessary, under the condition of FIG. 4, the vicinity of the free ends 44 and 45 is elastically deformed against the elasticity of the elastic wire rod, and the engagement is released. When this engagement is newly performed, the free ends 44 and 45 are firmly inserted into the catch 12 with the hook 14. In the process, the vicinity of the free ends 44 and 45 is elastically deformed along the hook 14, and the hook 14 and the free ends 44 and 45 are engaged over the hook 14. This engagement is a kind of temporary fixing, and also has a role of preventing the accessory frame 30 from being undesirably dropped.

[0008]

According to the present invention, a required elastic engaging member including a fixed end, a free end, and a protruding portion is provided, and a required receiving member corresponding thereto is provided. A plurality of the receiving members are provided, and a hook is provided in the vicinity of one of the receiving members to lock and hold the free end after the engagement by the receiving member is released. The main feature is that no hook is provided near the tool. This eliminates the need for the complicated operation of pursuing the conventional V-shaped spring, and provides an easy-to-use accessory-equipped lighting fixture that can easily and quickly attach and detach accessories.
