Abstract

(57) [Abstract] [Purpose] The present invention relates to a lighting device for a learning desk or the like that can be mounted on a bookshelf or the like that is erected on the desk. And with a simple structure, it can illuminate any part of the desk depending on the convenience of work on the desk, right-handed or left-handed users, and the structure is simple, and the lighting device for the learning desk can be manufactured at low cost. The purpose is to do. [Structure] The left and right end portions of the lighting box body can freely move in and out in the front-rear direction, and one end portion of each is centered on the other end side,
It is supported so as to be rotatable and protruded, and is fitted into a guide recess formed in the front-rear direction at the front of the widthwise center of the bottom surface of the shelf plate, rather than slightly rearward of the widthwise center of the lighting box. The stopper protrusion is formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device for a learning desk or the like that is attached to a bookshelf or the like that is erected on the desk.

[0002]

[Prior art]

 In the above-mentioned conventional device, two rotating arms are arranged in a substantially X-shaped crossing arrangement, and a slider is provided in the intersecting portion so that the opening rotating arms can be slid in the longitudinal direction of each other. These two rotating arms are rotatably attached to the lower surface of the shelf plate and the distal end portions thereof are rotatably attached to a single horizontally long illumination lamp. (For example, Jikken Sho 61-3060)

For this reason, the illumination direction and the illumination angle of the illumination lamp can be freely set depending on the convenience of the work on the desk, right-handed and left-handed users, but since the front side is illuminated, I couldn't pull it forward parallel to the shelves, so I couldn't even illuminate every part of the desk.

[0004]

[Problems to be solved by the device]

 The present invention has a simple structure, and can provide an illumination device for a learning desk that can irradiate any part of the desk and can be manufactured at low cost depending on the convenience of work on the desk or right-handed or left-handed users. Is an issue.

[0005]

[Means for solving the problem]

 The left and right ends of the lighting box can be moved in and out in the front-rear direction, and one end of each is supported so as to be rotatable and projectable about the other end side, and at the center of the width direction of the lighting box. A stopper protrusion that fits into a guide recess formed in the front-rear direction is formed in the front part of the lower surface of the shelf board in the substantially central part in the width direction rather than the rear part.

[0006]

【Example】

 2 shows a use state of the present invention, reference numeral 1 denotes a desk bookshelf standing upright on a rear portion of a desk 10, and a lighting device 3 is attached to a lower surface of a shelf board 2 of the desk bookshelf 1. .

The desk bookshelf 1 includes left and right side plates 11, 11, a shelf plate 12 mounted between the upper parts of the left and right side plates 11, 11, and a rear plate 13 mounted between the rear end portions of the left and right side plates 11. , And the like, which project on the shelf plate 12 at the inner surface of the upper end of the rear plate 13 and the like. Then, on the inner surface of the shelf plate 12 of the left and right side plates 11 on the lower side, support ridges 15, 15 of the lighting device 3 are formed so as to project inward in the front-rear direction.

The illuminating device 3 has an opening on the lower surface, an illuminating lamp 31 inside, and an illumination box body 33 having a cover 32 attached to the front surface, and rails attached to the left and right ends of the illumination box body 33. It is composed of members 4 and 4.

The rail members 4 and 4 are symmetrical with respect to the synthetic resin material, and the side ends thereof are formed in an arcuate shape so as to be gradually separated from the left and right side plates 11 as the planar shape goes rearward, and the supporting protrusions are formed on the side end faces. A guide groove 41 into which 15 is fitted is formed along the side edge shape.

The dimensional relationship between the support ridges 15 and the guide grooves 41 is such that the support ridges 15 fit into the guide grooves 41 even if the illumination box body 33 is pulled out to a predetermined range in parallel with the shelf plate 12. The supporting ridges 15 are dimensioned to fit in the guide grooves 41 even when one end of the illumination box body 33 pivotally projects to the predetermined position around the other end.

On the other hand, a guide recess 121 is formed in the front-rear direction in the lower front part of the shelf board 12 in the substantially central portion in the width direction. Correspondingly, a guide recess 121 is formed on the upper surface of the illumination box body 33 in the central portion in the width direction. Further, a stopper protrusion 331 that fits into the guide recess 121 is formed so as to protrude upward.

That is, as shown in FIG. 1, when one of the right side and the left side is pulled out from the state where the lighting box body 33 is stored on the lower surface of the shelf plate 12, the other end portion is stopped and It projects forward so that the end of the can rotates. Along with this, the stopper protrusion 331 also moves forward, and eventually collides with the front end of the guide recess 121 and stops.

When the central portion is pulled forward, both left and right end portions also move forward, and the stopper projection 331 eventually collides with the front end of the guide recess 121 and stops.

In the above-described embodiment, the stopper protrusion 331 is projected upward from the illumination box body 33 and fitted into the guide recess 121 formed on the lower surface of the shelf plate 12. As shown, a long hole 332 is formed in the front and rear direction of the upper surface of the central portion in the width direction of the lighting box body 33, and a stopper projection 122 to be fitted in the long hole 332 is provided in the front portion of the lower surface of the central portion in the width direction of the shelf plate 12. You can do it as well.

[0015]

[Effect of device]

 As described above, according to the present invention, the left and right end portions of the lighting box body can be moved in and out in the front-rear direction, and the respective end portions are supported so as to be rotatable and projectable about the other side, and the lighting box body and the shelf are Since a stopper protrusion and a guide recess, or a long hole and a stopper protrusion are formed corresponding to approximately the center in the width direction of the plate, the lighting box body can be pulled out by pulling either side edge toward you. Both the left and right sides can be set to be slanted out, and it is possible to set the irradiation direction and irradiation angle freely depending on the convenience of work that can be placed on a desk or for right-handed and left-handed users. Instead, it can be pulled out forward in parallel with the shelf plate, so that it is possible to irradiate any part of the desk surface more appropriately than before. It has a simple structure that supports both left and right ends of the lighting box, and forms a guide recess, or a long hole and a stopper projection, corresponding to the lighting box or shelf, respectively. It is low in number, easy to process, and inexpensive to manufacture.
