Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting device for a learning desk or the like.

[Conventional technology]

Some learning desks and the like have a lighting device incorporated in an upper shelf such as a bookcase installed on the top plate. As an illumination device of this type, there are a device fixed to the upper shelf and a device that can be pulled out forward from the upper shelf.

[Problems to be solved by the device]

However, in the case of the former fixed type, its mounting position is fixed, so in order to illuminate a wide area on the desk top plate, it is necessary to mount it in a state protruding from the upper shelf forward, and the lighting device is always installed from the upper shelf. Because it is in a protruding state, it is an obstacle. or,
In the case of the latter that can be pulled out from the upper shelf forward, if lighting is not necessary, storing it in the upper shelf will not hinder, but when using the lighting, the lighting fixtures from the upper shelf It is necessary to pull it out and it is troublesome to handle.

In view of the above points, the present invention provides a lighting device for a learning desk,
When using it, it is possible to pull out from the upper shelf etc. with a simple one-touch operation to widely illuminate the desk top plate, and when not in use, provide a lighting device for a learning desk or the like that can be stored without obstruction. There is something to do.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a lighting device for a learning desk or the like according to the present invention comprises an illuminating device which is attached to a lower surface of a shelf of an upper shelf provided to the learning desk or the like so as to be able to be pulled out forward from the shelf. Energizing means for elastically urging the illuminating device forward from the lower surface of the shelf plate and engagement provided so as to be detachably provided between the shelf plate and the illuminating device in a state where the illuminating device is housed on the lower surface of the shelf plate. Means and
And an engagement releasing means for releasing the engagement of the engaging means.

[Action]

The lighting device in the learning desk or the like according to the present invention is configured as described above, and when the lighting is not required, the lighting device is pushed into the upper shelf and the lighting device is housed in the upper shelf by the engaging means. It is connected and fixed to the lower surface of the shelf board. And
When the illuminator is used, if the engaging means for fixing the shelf plate and the illuminator is disengaged by the disengagement means, the illuminator is pushed forward by the urging means, and the desk top plate is released. The top can be widely illuminated.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

FIG. 1 shows a learning desk 1 equipped with a lighting device 1 according to the present invention.
2 is a perspective view of the desk main body, 3 is an upper shelf connected and fixed to a rear end portion of the top plate 4 of the desk main body 2, and 5 is mounted in the upper shelf 4 so as to be stored and withdrawable. It is a lighting device.

As shown in FIGS. 2 and 3, for example, the lighting device 5 includes a lighting fixture 8 incorporating a fluorescent lamp 7 between sliders 6 provided on the inner surfaces of both side plates 32 below the shelf plate 31 of the upper shelf 3. Slidably attached to the illuminating device 8 so that the illuminating device 8 can be pulled out forward of the shelf plate 31, and the rear part of the illuminating device 8 and the shelf plate 31 or the side plate 32 of the upper shelf 3 are connected by a crank rod 9. Further, the crank rods 9 located on both sides are connected by a square rod 10, and the square rod 10 is urged by a spring 11 in a direction in which the crank rod 9 extends forward, so that the lighting fixture 8 is always racked. It is attached in a state in which it is elastically biased in the direction of pushing it forward from the plate 31. Further, hooks 12 and 13 are provided on the lower surface of the shelf plate 31 and the rear portion of the illuminating device 8 as engaging means capable of engaging with each other when the illuminating device 8 is housed on the lower surface of the shelf plate 31. The lighting fixture 8 can be connected and fixed to the lower surface of the shelf plate 31. Then, on the upper surface of the illuminator 8, as a disengaging means for disengaging the hooks 12 and 13, the base end portion 14a is made to face the front surface of the front plate 81 of the illuminator 8 and the tip portion 14b is provided. Shelf 3
(1) A spring 15 moves forward and backward by a spring 15 an operating lever 14 formed in a taper shape corresponding to the outer surface of a hook 12 provided on the lower surface and slidable back and forth in a state of overlapping with a hook 13 provided on the lighting fixture 8. It is provided in a biased state.

According to the illuminating device 1 configured as described above, when illumination is not required, the illuminating tool 8 is pushed into the lower surface of the shelf plate 31 of the upper shelf 3 to provide the lower surface of the shelf plate 31 and the illuminating tool 8 respectively. The hooks 12 and 13 are engaged with each other so that the illuminator 8 and the shelf plate 31 are connected and fixed, and the illuminator 8 is housed in the upper shelf 8 without obstructing the desk top plate 4. Then, when illumination is required, the operation lever 14 located on the front surface of the front plate 81 of the illuminator 8
When the tip portion 14a of the illuminator 8 is pushed inward, the taper surface of the tip portion 14b of the operating lever 14 is changed to the hook 1 of the illuminator 8 as shown in FIG.
The hook 12 on the lower surface of the shelf plate 31 engaged with 3 is pushed upward to release the engagement of both hooks 12 and 13, and the lighting fixture 8 elastically attaches the lighting fixture 8 forward through the crank rod 9. The urging spring 10 pushes the shelves 31 forward, so that it is possible to widely illuminate the desk top plate 4 with the illuminator 8 positioned in front of the shelves 31. Further, when the lighting is no longer needed, if the lighting tool 8 is inserted into the lower surface of the shelf board 31 against the biasing force of the spring 10, the hooks 12 and 13 are engaged again, and the lighting tool 8 is moved to the lower surface of the shelf board 31. It is connected and fixed and stored in the upper shelf 3.

As described above, the lighting device according to the present invention can be easily installed by simply pushing the lighting device 8 into the lower surface of the shelf plate 31 when it is not needed.
The illuminator 8 can be housed inside, and at the time of illumination, the illuminator 8 can be pulled out to the front of the shelf plate 31 by a one-touch operation by simply pushing the base end portion 14a of the operation lever 14, which makes the handling extremely easy. The operation lever 14 for releasing the engagement of the hooks 12 and 13 may be provided on the shelf plate 31 side. As means for releasing the engagement between the hooks 12 and 13, for example, one of the hooks 12 or 13 is slid sideways to release the engagement between the hooks 12 and 13 as shown in FIG. Good. Further, by interlocking the operation lever 14 as a disengagement means of the both hooks 12 and 13 with the switch of the fluorescent lamp 7, the fluorescent lamp 7 is turned on only by pulling out the illuminating tool 8 with the operating lever 14. You may do it.

[Effect of device]

As described above, the lighting device according to the present invention can be widely used to illuminate the desk top plate by pulling it forward from the inside of the upper shelf with a simple operation of a touch when using it, and pushing it into the upper shelf when unnecessary. It can be stored easily without getting in the way.
