Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to the improvement of a lighting device placed on the underside of a shelf installed on a desk top. The present invention relates to a lighting device for mounting under a shelf on a desk top, which can be pulled out diagonally forward to improve illumination on the desk top, and can be easily stored in conjunction.

[Conventional technology]

Conventional lighting devices that are attached to the underside of the shelf on the top of a desk are designed to interlock the lights placed on both sides.
Using a book connecting stay, the drawer and storage operations of the lamps on both sides were linked by operating one lamp and transmitting the tensile and compressive forces applied to the connecting stay to the other lamp. For example, as disclosed in Utility Model Application Publication No. 9378 of 1982,
A plate is loosely fitted to each of the support shafts vertically installed near both ends of the front edge of the lower surface of the shelf, and the front part of one plate is connected to the support shaft, and the rear part of the other plate is connected at one point. The books are pivotally connected by a connecting stay, and one end of each plate is interlockingly connected to a support rod pivoted to the center of the light fixture, and furthermore, the shelf of the light fixture is connected to a horizontally long rail provided on the front edge of the lower surface of the shelf. The suspension rods installed at the ends near the center are fitted together so that they can be slid laterally.If one of the lamps is moved forward, the outside part of the lamp can be moved forward, and the inside part can be slid to the outside and pulled out. The other light fixture can also be pulled out symmetrically, and if one light fixture is stored under the shelf by performing the reverse operation, the other light fixture will also be stored in conjunction with the other light fixture, but due to the dimensional error of the connection stay and the plate body. If there is a misalignment in the interlocking of the lights on both sides due to installation errors, or if one light fixture is operated to interlock the other, the connection stay may be bent due to the operation in the direction of compressing the connection stay. Therefore, the connecting stay must be strong enough to withstand the compressive force even when the operation of the linked lamp is heavy. Not only does this tend to increase costs, but also requires labor to attach and set the connecting stay.

[Problem that the invention attempts to solve]

In view of the above-mentioned situation, the present invention aims to solve the problem of bending of the connecting stay that occurs when one light fixture is operated to be pulled out or stored from the bottom surface of the shelf, and the other light fixture is linked to the operation. It prevents misalignment and rattling of the light fixtures on both sides due to dimensional errors in the connecting stay, and allows the light fixtures on both sides to be pulled out and stored symmetrically and smoothly.It is inexpensive, has a simple structure, and can be easily installed under a shelf. The object of the present invention is to provide a lighting device for mounting under a shelf on a desk top plate.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention arranges oblong lamps adjacent to the lower surfaces of both sides of the board fixed to the lower front edge of the shelf on the desk top plate, and attaches the end of the lamp nearer to the center of the board. The provided sliding hanging support rod is fitted to the horizontally long rail provided on the board so as to be able to slide laterally, and the central part of the lamp is pivoted at one end to both ends of the board, and The control piece is fixed to the other end of the support rod that protrudes from both sides with the support shaft in between, and both free ends of the control piece on one side and both free ends of the control piece on the other side are crossed. A lighting device for mounting under a shelf on a desk top board is constructed by linking the lamps on both sides by pivoting the two connecting stays at both ends.

[Effect]

The lighting device for mounting under a shelf on a desk top board of the present invention, which is constructed as described above, has one end of a support rod pivoted to both ends of a board fixed to the bottom surface of a shelf on a desk top board. Both free ends of the control pieces on both sides, which are fixed to the support rod while protruding from both sides with the support shaft in between, are crossed.
By pivoting to both ends of the book connecting stay,
Since the light fixtures on both sides are linked, when one light fixture is operated and the other light fixture is pulled out and stored from the bottom surface of the shelf, the control piece rotates around the support shaft and the two
A tensile force is applied to one of the book connecting stays, and even if the control piece is rotated in the opposite direction, a tensile force is applied to the other connecting stay, allowing the interlocking operation of the lamps on both sides. can be done smoothly.
