Description

[Detailed description of the invention] This invention relates to a desk with a bookshelf, and more specifically, it is used by connecting a cabinet to one side of the top plate, connecting the main body of the desk with a bookshelf to the other side, and holding the top plate in a horizontal position. The purpose of the desk was to be installed in the bookshelf of the desk itself, so that it could be stored when not in use, and when in use, it could be rotated and pulled out to the top of the top. The purpose is to simplify the configuration and operation of the lighting equipment.

Conventionally, in this type of desk with a bookshelf, the lighting device to illuminate the top surface was extremely primitive, simply placing a fluorescent lamp stand on the top board, so it was necessary to simply narrow the top surface. However, if the table top can be rotated and folded into the main body of the desk, the fluorescent light stand must be placed on and off each time the table top is folded or pulled out. However, it was extremely troublesome to handle.

This proposal was devised to eliminate the above-mentioned drawbacks, and the main point is that the top plate 4 of the desk body B that has a bookshelf
One side is connected in a fixed or rotationally foldable manner, a cabinet C is fixedly or removably connected on the other side of the top plate 4, and a lighting fixture 5 is installed in the bookshelf of the desk body B so that it can be rotated and drawn out. At the point. That is, in a desk with a bookshelf in which one side of the top plate 4 is connected to the cabinet C and the other side is connected to the shelf board of the bookshelf in a horizontal state, on the lower surface of the shelf board 6 of the desk body B, An arm 8 is rotatably supported in the horizontal direction by a pivot 9, leaving the base end 8 at one end thereof, and the base end 8 on the base end side from the pivot point is supported by the pivot 9 of the arm 8. 'A balance arm 13 is rotatably mounted on the upper surface by a pivot 12, and a box 14 with a lighting switch attached or installed therein is fixed at the free end of the arm 13, and the arm 8 is slidably fitted into the box 14. A guide groove 10 to be fitted is formed as a recess or a notch on the upper surface, and a slide edge 11 is provided at a predetermined position on the upper edge of the guide groove 10 at least near the pivot axis to prevent the arm 8 from coming off upward. The present invention is characterized in that a lighting fixture 5 is provided so as to be slidable back and forth in the longitudinal direction of the arm 8. A detailed explanation will be given below based on a configuration example in which the top plate 4 is rotatably and foldably connected to the desk body B. The desk A is composed of a desk body B and a cabinet C. The bookshelf is 2, the lower part is the cabinet storage part 3, and the base plate is 1.
A top plate 4 is rotatably attached to the front edge with a hinge or pivot, and when not in use, it stands up and is folded to the front of the bookshelf 2, and when in use, the bottom surface of the tip is placed on the top surface of a separately prepared cabinet C. It is supported so that it is in a horizontal state, and in addition, a lighting fixture 5 is attached to a predetermined part of the bookshelf 2 of the desk body B so that it can be drawn out and used.
That is, the lighting fixture 5 is attached to the bookshelf 2 as shown in FIGS.
It is attached to the lower surface of the shelf board 6 and can be stored between the bookshelf side plates 7 and 7 parallel to the front edge of the shelf board, and the concrete structure includes an arm provided on the upper surface of the lighting fixture 5 so as to be able to slide with the lighting fixture. One side of 8 (second
(Right side in the figure) The end portion is supported horizontally rotatably by a pivot 9 fixed to the lower surface of the shelf board, and a guide groove 10 into which the arm 8 is slidably fitted is provided on the upper surface of the lighting fixture 5. By attaching a slide edge 11 formed by a notch to a predetermined position on the upper edge of the guide groove 10 and hooking this edge 11 to the arm 8, the illumination device 5 can be slid back and forth in the longitudinal direction of the arm 8. There is. Therefore, when the lighting fixture 5 of the present invention is not in use, it is stored on the underside of the shelf board 6 as shown in FIG. 8 and pulled out in the longitudinal direction to reach above the horizontal top plate 4, thereby illuminating the top surface of the top plate.

In addition, according to the above configuration, the arm 8 by the pivot 9
There is a risk that the pivot portion of the arm 8 may warp or play due to the load of the arm 8 and the lighting fixture 5. In order to prevent this, in this proposal, the base end portion 8' of the arm 8 is located on the side of the pivot point of the pivot 9. Press down and hold. For example, as shown in FIG. 2, a balance arm 13 is rotatably attached to the upper surface of the base end 8' by a pivot 12, and at the other end of the arm 13, a box 14 with a lighting switch or the like attached or installed therein. is fixedly installed so that the load of the balance arm 13 box 14 is applied to the base end 8' of the arm 8. In this case, a stopper 1 is installed on the bottom surface of the shelf board to prevent the balance arm 13 from rotating inadvertently.
5... shall be provided. Furthermore, as another example of the structure for preventing the deflection and rattling of the pivoting part of the arm 8 by the pivot 9, the rotation of the arm base end 8' as the arm 8 rotates from the storage of the lighting fixture 5 to the drawer usage state. A presser plate 16 may be provided to prevent upward movement of the base end over a range.

On the other hand, the cabinet C that horizontally supports the top plate 14 in use forms a drawer or magazine rack, etc., and a drawer handle 17 that is provided by forming a predetermined hole in the top plate and protruding from the bottom surface of the top plate 4.
It is designed so that it can be fitted and supported.

In the above-mentioned main idea, the lighting installed inside the bookshelf of the desk body can be used both when the top plate is rotatable and foldable as in the embodiment, and when the top plate is fixed to the desk body and cabinet. The top surface of the top plate can be easily and reliably illuminated by simply pulling out the ingredients and placing them on the top plate, eliminating the hassle of placing and lowering separately prepared fluorescent light stands on and off the top plate one by one. It is completely unnecessary, and when it is not in use, it is completely stored inside the bookshelf, so there is no danger of it getting in the way of operations when folding or pulling out the top board, and when the light is in use, the arm 8 can be rotated around the axis 9 and placed inside the bookshelf. There is an advantage that the lighting device 5 can be set at a desired position by pulling it out from the arm 8 and then sliding the lighting device 5 with respect to the arm 8.

In addition, in this case, by using the balance arm 13 or the holding plate 16, it is possible to prevent the pivot portion of the pivot 9 from bending or wobbling due to the load of the arm 8 and the lighting fixture 5, and the top plate 4 can be placed horizontally. The support cabinet C has the advantage that the drawer handle 17 on the lower surface of the top plate is fitted and supported through the hole formed in the top plate, so that the connection of the top plate 4 and the cabinet C is ensured.
