[Industrial applications]

 The present invention relates to a spotlight adapter for attaching a spotlight to a lighting duct, and more particularly to an adapter having a function of preventing the spotlight attached to the lighting duct from being stolen.

[0002]

[Prior Art]

 Some conventional spotlights include an adapter 3 for detachably attaching the spotlight 1 to the lighting duct 2 as shown in FIG. This adapter 3 is disclosed in, for example, Japanese Patent Laid-Open No. 54-127596, and as shown in FIGS. 1 and 2, the housing 4, the insertion portion 5 provided on the top of the housing 4, and the housing 4 An operating lever 7 which protrudes from the housing 4 through the side slit 6 and is rotatable in a range of about 90 degrees, and an accommodating position which is accommodated in the insertion portion 5 in association with the rotation of the operating lever 7 ( 2) and a holding piece 9 configured to take two positions, an engaging position (FIG. 1) protruding from the slit 8 on the side of the insertion portion 5.

In order to attach the spotlight 1 to the lighting duct 2, first, the adapter 3 is placed in a state shown in FIG. 2, that is, the operation lever 7 is positioned at a right angle to the longitudinal direction of the insertion portion 5, and The holding piece 9 is set to the accommodation position. Next, the insertion portion 5 is inserted into an opening (not shown) on the lower surface of the lighting duct 2, and in this state, the operation lever 7 is rotated in the direction of arrow A in FIG. 2 by about 90 degrees to the fixed position shown in FIG. .. As a result, the holding piece 9 is interlocked with the operating lever 7 to project in the horizontal direction to take the engaging position, and engage with the holding groove (not shown) formed inside the lighting duct 2 as shown in FIG. By fitting, the adapter 3 is locked in the holding groove, and the spotlight 1 is held and fixed to the lighting duct 2. When the spotlight 1 is removed from the lighting duct 2, the reverse operation to the above is performed. In this way, the spotlight 1 can be easily and detachably attached to the lighting duct 2 only by operating the operation lever 7.

[0004]

[Problems to be solved by the device]

 As described above, the conventional adapter 3 described above is a convenient one in which the spotlight 1 can be easily attached and detached simply by rotating the operation lever 7. However, the ease of attachment and detachment of the adapter 3 means that the spotlight 1 attached to the lighting duct 2 may be easily removed and stolen, and such a theft should be prevented. There was a problem that I could not do it.

The present invention has been made to solve such a problem, and provides a spotlight adapter capable of preventing theft of a spotlight attached to a lighting duct with a simple structure. The purpose is to

[0006]

[Means for Solving the Problems]

 To achieve the above object, the present invention has a rotatable operation lever, and fixes the spotlight to the lighting duct by rotating the operation lever to a fixed position while the operation lever is inserted into the lighting duct. In the spotlight adapter configured as described above, a cover for locking the operation lever in the fixed position is provided.

[0007]

[Work]

 According to the above configuration, the operation lever is locked at the fixed position by the cover and is prevented from rotating from the fixed position.

[0008]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a spotlight adapter to which the present invention is applied. Reference numeral 10 in the figure is a cover attached to the conventional adapter 3 in order to prevent the spotlight 1 from being stolen. The cover 10 has substantially the same shape as a portion of the side portion of the housing 4 of the adapter 3 adjacent to the operation lever 7 (a broken line portion in the figure), and has a hole 10 a in the cover 10 and a hole 4 a in the housing 4. It is fixed to the housing 4 by tightening the threaded screw 11. Further, in this fixed state, one side 10b of the cover 10 is arranged to be in contact with or close to the operation lever 7.

According to such a configuration, after the spotlight 1 is attached to the lighting duct 2 as described above, the cover 10 is attached to the housing 4 of the adapter 3 so that the side 10b of the cover 10 is The operating lever 7 in the fixed position or slightly rotated from the fixed position is locked to prevent the operating lever 7 from rotating, thereby maintaining the holding piece 9 of the adapter 3 in the engaging position. As a result, it becomes impossible to remove the spotlight 1 from the lighting duct 2 unless the screw 11 is removed using a screwdriver or the like, so that the spotlight 1 can be prevented from being stolen with a simple structure. ..

The structure for fixing the cover 10 to the housing 4 of the adapter 3 may be arbitrary, but the structure using the screws shown in the embodiment is the simplest and practical.
