Abstract

PURPOSE:To easily remove a cover without falling down on a floor, if not supported by hand, by having the first protrusion of the cover latched by the second protrusion of an equipment mainframe when a cover fitting is operated to release the cover from being latched. CONSTITUTION:A lighting equipment is so constructed that, when a cover fitting 28 provided on the equipment mainframe 21 is operated to release a cover 26 from being latched by a latch 31, the cover 26 may fall down by its weight and by removed from the equipment mainframe. The cover 26 has the first protrusion 35 protruded sideways from the side wall, and the equipment mainframe 21 has the second protrusion 36 which is protruded by being energized from the side wall to the first protrusion 35 side to latch the first protrusion 35 of the cover 26, falling when removed from the equipment mainframe, and escaped to the side wall by being thrusted by the first protrusion 35 when the latched cover 26 is pulled down. The cover 26 falls down when the cover fitting 28 is operated to release the latch of the equipment mainframe 21, but is free from fall-down on a floor because, on its way, the first protrusion 35 is latched by the second protrusion 36.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is provided with a fall prevention device that can prevent the transparent cover from falling when attaching and detaching the translucent cover to the device body. It relates to lighting equipment.

[Prior Art] FIG. 5 is a sectional view showing a conventional lighting fixture disclosed in, for example, Japanese Utility Model Application Publication No. 60-50417.

It is a backing for Reference numeral 12 denotes a downwardly protruding protrusion fixed to the instrument body l, which is in pressure contact with the backing 11 of the frame 9 hooked to the hooking member 6 to prevent insects from entering the instrument. be.

Conventional lighting equipment is configured as described above, so
When the translucent cover 8 is pushed up by placing its frame 9 against the slope 6a of the hooking member 6 of the cover mounting bracket 4, the device body 1
It can be attached to. At this time, the cover mounting bracket 4 is pushed by the frame 9 and once moves inward, and when the frame 9 is latched to the latching member 6, it returns to its original position, that is, the latching position of the frame 9.

On the other hand, the cover 8 attached to the instrument main body 1 can be easily removed by its own weight when the push button 5 is pushed inward and the frame 9 is released from the latching member 6.

[Problems to be Solved by the Invention] In the conventional lighting equipment, as described above, when the push button 5 of the cover mounting bracket 4 is pushed inward to release the frame 9 from the latching member 6, the cover is removed. 8 falls off under its own weight and comes off. Therefore, when removing the cover 8 from the instrument body 1, it is necessary to press the push button 5 while supporting the cover 8 from below with your hand to prevent it from falling. The work was always accompanied by anxiety. This was especially true when removing work was done in places with poor footing.

Furthermore, if the push button 5 is pressed without supporting the cover 8 with one's hand, the cover 8 may fall onto the floor or the like and be damaged.

This invention was made to solve these conventional problems, and provides a lighting fixture that can be easily removed without supporting the cover with your hands or dropping it on the floor etc. The purpose is to

[Means for Solving the Problems J] The lighting equipment provided by the present invention is such that when the cover is unlatched by operating the cover mounting bracket provided on the fixture body, the cover is unlatched. The cover is of a structure that falls under its own weight and detaches from the main body of the device, and the cover is
The first protrusion of the cover has a first protrusion that protrudes laterally from the side wall, and the instrument body is urged from the side wall toward the first protrusion to protrude, and the first protrusion of the cover detaches from the instrument body and falls. The cover is latched, and when the latched cover is pulled downward, it has a second protrusion that is pressed by the first protrusion and retreats toward the side wall.

[Effect]

The cover of this lighting fixture will fall downward when the cover is released from the fixture body by operating the cover mounting bracket.
On the way, the first protrusion is hooked to the second protrusion, so it will not fall onto the floor or the like. In addition, when the cover is latched to the instrument main body by the first protrusion being latched to the second protrusion, when the cover is pulled down, the second protrusion is pressed by the first protrusion and the cover is retracted. So it can be easily removed.

In this manner, when the cover mounting bracket is operated, the cover is temporarily attached to the main body of the instrument, so there is no need to support the cover by hand to prevent it from falling.
