[Technical background of the invention]

Recently, as a light control cover mounting structure for lighting equipment having a light control cover, the light control cover can be attached and removed with one touch, as described in Japanese Utility Model Publication No. 58-13541 and Publication No. 58-13543. What has been done is considered.

To briefly explain the light control cover mounting structure, in FIGS. 1 and 2, 1 is the lighting fixture body that is mounted on the fixture mounting surface A such as the ceiling surface, 2 is the light control body 2a and its edge frame 2b, The edge frame 2b of this light control cover 2 is provided with an insect repellent packing 3 on the inner periphery of its upper end, and the insect repellent packing 3 is provided on the outer periphery of the device main body 1.
An edge plate 1a is formed to be pressed against. A is a lamp installed inside the appliance main body 1.

Reference numeral 4 denotes light control cover hooking members provided on both sides of the device main body 1, and this hooking member 4 is connected to the third
As shown in the figure, the proximal end is supported by a support fitting 5 attached to the lower surface of the instrument main body 1 so as to be rotatable, and a coil spring 6 provided on the support fitting 5 allows the instrument body to be rotated outwardly. Being pressed. This hook member 4 is provided with hook insertion holes 4a at two locations, for example.

Moreover, on the inner surface of the edge frame 2b of the light control cover 2,
A hooking member 7 having a hooking claw 7a facing each hooking claw insertion hole 4a of the hooking member 4 is fixed, and the light control cover 2 is configured to insert the hooking claw 7a into the hooking member 4. It is attached to the instrument main body 1 via the hook member 4 by engaging with the retaining pawl insertion hole 4a.

Further, the edge frame 2b of the light control cover 2 is provided with a lock release pin 8 that faces the hook member 4. This locking release pin 8 is slidably supported by a guide member 9 attached to the edge frame 2b so as to be supported by the locking member 7, and a push button 8a is provided at the outer end thereof. 10 is a return coil spring interposed between the guide member 9 and the push button 8a, and the unlatching pin 8 is separated from the hook member 4 by the spring force of the coil spring 10, that is, the push button 8a. is held in a state where it protrudes outside the edge frame 2b.

In this light control cover mounting structure, the light control cover 2 can be removed by pressing the push button 8a and rotating the hook member 4 with the latch release pin 8 as shown by the chain line in FIG. The light control cover 2 can be removed simply by separating it from the latch claw 7a and pulling down the light control cover 2 in this state. According to this light control cover mounting structure, the light control cover 2 can be easily removed with a single touch. can be done.

In addition, in order to attach the light control cover 2 to the instrument body 1, it is sufficient to press the light control cover 2 onto the instrument body 1, and when the light control cover 2 is pressed against the instrument body 1,
The hooking member 4 is pushed and rotated by the hooking pawl 7a, and when the hooking pawl 7a comes to a position that matches the hooking pawl insertion hole 4a of the hooking member 4, the hooking member 4 is pushed by the hooking member 7a by the spring force. The latch claw 7 is pushed to the side and inserted into the latch claw insertion hole 4a.
Since the light control cover 2 can be installed easily with a single touch, the light control cover 2 can be easily attached.

[Problems with background technology]

However, in the above light control cover mounting structure, the latch claw 7a provided on the latch member 7 on the light control cover 2 side is placed laterally with respect to the latch claw insertion hole 4a provided on the hook member 4 on the device main body 1 side. Since the light control cover 2 is inserted and engaged from the side, when the light control cover 2 is pushed from the side when wiping and cleaning the outer surface of the light control cover, etc.
This poses a problem in that there is a danger that the light control cover 2 may fall. This is because when no external force is applied to the light control cover 2, the insect-proof gasket 3 prevents the light control cover 2 from shifting, but when a force is applied to the light control cover 2 in a horizontal direction, the light control cover 2 is prevented from shifting. This is because the cover 2 shifts while bending the insect repellent gasket 3, and when the light control cover 2 shifts in the direction in which the hooking member 4 and the hooking member 7 are opposed to each other, the hooking pawl 7a is hooked. The light control cover 2 will come off from the latch claw insertion hole 4a of the member 4 and fall.

In addition, in order to prevent the light control cover 2 from falling due to the shifting movement of the light control cover 2, the latching claw 7a is enlarged so that the depth of engagement of the latching claw into the latching claw insertion hole 4a is set to the light control cover 2. The depth of engagement of the latch claw with the latch claw insertion hole 4a can be made deeper than the amount of displacement in step 2, but if the depth of engagement of the latch claw with the latch claw insertion hole 4a is increased in this way, when the latch claw 7a is detached from the latch claw insertion hole 4a, As the hooking member 4 rotates, the amount of pushing up of the hooking claw 7a (the amount of pushing up of the light control cover 2) also increases, so that the insect repellent hitting the edge plate 1a of the device body 1 increases. In order to push up the latch claw 7a significantly against the elastic resistance of the seal 3, it is necessary to press the latch release pin 8 with a fairly strong force, which makes it difficult to remove the light control cover 2 with good operability. Therefore, it is practically problematic to enlarge the latch claw 7a so that the depth of engagement of the latch claw with the latch claw insertion hole 4a is deeper than the amount of displacement of the light control cover 2. Ta.

[Purpose of invention]

This idea was created in view of the above-mentioned circumstances, and its purpose is not only to allow the light control cover to be easily attached and removed with a single touch, but also to allow the light control cover to move horizontally. To provide a highly safe mounting structure for a light control cover of a lighting device, which prevents the light control cover from falling even when the light control cover is shifted.

[Summary of the idea]

That is, this device has a pair of guide plate portions extending downward on both sides on the lower surface of the instrument main body, and the inner edges of the guide plate portions are inclined downward and outward, respectively, and the guide plate portions are inclined downwardly and outwardly. A spring receiving plate with a spring hook recessed outward is provided almost vertically at the upper end of the inner edge of the plate, and a V-shaped spring is installed on the side of the light control cover to restrict its vertical movement. Then, the distal ends of the pair of spring legs of this V-shaped spring are engaged with the spring hooking portions of the spring receiving plate by the expanding force of the V-shaped spring, and the distal ends of this V-shaped spring are connected to the spring receiving portions of the spring receiving plate. A retaining portion to be hooked on the back side of the plate is formed, and the light control cover is formed into a V shape by sandwiching both spring legs of the V-shaped spring from both sides and pressing an operating member protruding from the outer surface of the light control cover. The device has a spring opening regulating member that moves toward the tip of the spring legs while compressing the spring to separate both spring legs from the spring hooking portion of the spring receiving plate. By pressing the V-shaped spring to the side, the spring leg of the V-shaped spring is guided by the inner edge of the guide plate part of the spring receiving plate and enters the inside of the guide plate part, and the expanding force of the V-shaped spring moves the spring leg into the spring receiver. The V-shaped spring was engaged with the spring hook part of the plate, and the light control cover was supported by the spring receiving plate, and the light control cover was displaced in the direction in which the V-shaped spring approached the spring receiving plate. In this case, the spring leg is expanded by the spring force of the V-shaped spring to prevent the spring leg from coming off from the spring retaining part, and if the light control cover moves in the opposite direction, the retaining part at the end of the spring leg is fixed to the spring retainer. The light control cover is prevented from falling by catching it on the back of the plate and preventing the spring leg from coming off from the spring latching part, and furthermore, by pressing the operation member, the V-shaped spring is controlled by the spring opening regulating member. The light control cover is removed by compressing the spring leg and separating it from the spring hook.
