[Conventional technology]

2. Description of the Related Art It is known that a study desk or the like equipped with a bookshelf has an undershelf light built into the lower surface of the shelf board of the bookshelf to illuminate the desk surface. This conventional undershelf light is supported so that it can slide forward and backward relative to the bookshelf, and is pivoted so that it can rotate around a horizontal axis, so that the illuminance distribution on the desk surface can be adjusted arbitrarily. , one of its specific configurations is shown in FIG.

In the figure, reference numeral 1 denotes a chassis with a built-in stabilizer, and slide plates 2 are attached to both left and right ends of the chassis 1. These slide plates 2 have projections 3 provided on their outer surfaces fitted into guide rails provided on a bookshelf (not shown), and
By meshing the gear 4 with a rack part along the guide rail, it is supported so as to be slidable in the front and rear direction, and the left and right movable side plates 5 are mounted on the front of the mutually opposing surfaces of the slide plate 2. It is rotatably supported.

Between the movable side plates 5, a reflector 7 that reflects light from the fluorescent lamp 6 downward, and a shade 8 positioned in front of the reflector 7 are supported.

The shade 8 is formed to have the same length as the reflecting plate 7, and its both ends are fitted and held in a cylindrical fitting part 9 provided at the front end of the movable side plate 5. Moreover, a cover part 10 that extends to the side wall of the bookshelf is integrally formed at the front end of the movable side plate 5, and is connected to the fitting part 9, and this cover part 10 connects the slide plate 2 and the guide rail. The engaging portion is covered from the front.

[Problem that the invention attempts to solve]

However, in this conventional undershelf light, since both ends of the shade 8 are fitted into the fitting portions 9 of the movable side plate 5, as is clear from FIG.
There is a problem in that a step 11 occurs at the boundary between the movable side plate 5 and the movable side plate 5.

In addition, when sliding or rotating the shelf light, the shade 8 located at the front is often held in the hand, so the fitting part between the shade 8 and the fitting part 9 is twisted. To increase rigidity,
A long fitting length is required, and the fitting portion 9 ends up covering the end of the shade 8 to a large extent. Moreover,
Since the front end of the movable side plate 5 is provided with a cover part 10 that covers the slide plate 2, the exposed length L of the front surface of the movable side plate 5 becomes longer and longer, making the movable side plate 5 quite conspicuous in appearance. Coupled with the occurrence of the step 11, there is still room for improvement in terms of appearance.

Therefore, the present invention can prevent the occurrence of a step at the boundary between the movable side plate and the shade, shorten the exposed length of the front surface of the movable side plate, and further reduce the length of the support portions at both ends of the shade. The purpose of the present invention is to provide a movable undershelf light that can ensure sufficient torsional rigidity.

[Means for solving problems]

Therefore, in the present invention, the length of the shade is formed longer than the length of the reflector, and both ends of the shade are led out in front of the slide plate.
At both ends of the connecting wall of this shade, cutouts are formed in a shape that allows the slide plate to escape, and the front parts of the side plates located on both sides of the shade are cut out at both ends of the shade. extending laterally along
While engaging this extension with both ends of the shade,
The tip of the extension part is provided with a receptacle that is flush with the circumferential surface of the shade and abuts both ends of the shade from the side, and also covers the engagement part between the slide plate and the support member from the front. A feature of the present invention is that a fitting portion is formed on the end face of the receiving portion to fit into the inner surfaces of both ends of the shade.

[Effect]

According to this configuration, the receiving portions of the movable side plates that extend to both ends of the shade are formed flush with the circumferential surface of the shade, and the fitting portions that fit into the inner surface of the shade are provided on the end surfaces of the receiving portions. , there is no difference in level between the shade and the movable side plate, and the boundary becomes less noticeable.

Moreover, since the fitting part goes inside the shade, it is hidden from the outside, and both ends of the shade are led out to the front of the slide plate, so both this shade and the receiving part of the movable side plate can The engagement portion between the slide plate and the support member can be covered and hidden from the front.

Therefore, compared to the conventional method, the exposed length of the front surface of the movable side plate can be shortened, and the presence of this movable side plate becomes less noticeable, which also eliminates the level difference at the boundary between the shade and the movable side plate. ,
The appearance of the front of the shelf light is neatly arranged.

In addition, due to the presence of the above-mentioned fitting portion, a sufficient fitting length between the shade and the movable side plate can be ensured, and
Since both ends of the shade are engaged with extensions provided on the movable side plate, both ends of the shade are sufficiently reinforced, and even though the front exposed length of the movable side plate is shortened, both ends of the shade are supported. It is possible to compensate for the torsional stiffness of the part.
