Description

[Detailed description of the invention] Industrial application field This invention is a study desk with an illumination lamp, especially a bookshelf installed at the back of the top board. This invention relates to a study desk with a sliding lighting device that can be slid in and out.

Prior Art and Problems When a study desk is used during the day or in a bright room with indoor lights turned on, it is necessary and sufficient to brightly illuminate only the top of the desk. However, if you are using your desk in a dark room with no room lights turned on, the desk lamp alone will not brighten the room.
It is often inconvenient.

In view of this inconvenience, conventionally,
As shown in Publication No. 16673, a translucent window is provided on the top surface of the shade on the top surface of a removable lighting fixture provided on the shelf board of a bookshelf installed on the top of a desk, and when the light fixture is pulled out, the above A device has been proposed in which light is emitted from the window toward the ceiling of the room to provide an indoor lighting effect. However, in this case, the lighting from the window only illuminates a part of the ceiling, just like spot lighting, and has the disadvantage that it is not possible to provide sufficient brightness in the room. It was hot. Therefore, in the above-mentioned known example, a light transmitting body covering the window portion is formed to have a zigzag cross section to diffuse light. However, it was still not possible to brightly illuminate a wide area of the room.

In view of the above-mentioned conventional technology, this invention allows the degree of indoor illumination to be adjusted arbitrarily by adjusting the degree to which the lamp is pulled out, thereby making it possible to harmonize the brightness of the top surface of the desk with the brightness of the room. ,
To provide a study desk equipped with a lighting fixture that does not cause a user of the desk to feel dazzling.

Means for solving the problem This invention aims to achieve the above-mentioned purpose by placing a
In a study desk body equipped with a lighting fixture that can be freely moved back and forth in parallel, the upper wall of the shade of the lighting fixture is formed in the shape of a front-down staircase with an alternating arrangement of horizontal parts and vertical parts, and the horizontal part is transparent or translucent. A vertical part is formed in the non-transparent part in the transparent part, and
A shielding plate that closes the space between the shelf board and the front edge of the shade of the light fixture in the retracted storage position is vertically mounted on the front edge of the shelf board so that it can be flipped up and rotated via a hinge part, and the front drawer of the light fixture is suspended. It is characterized in that the shielding plate is configured to expand upward in conjunction with the shielding plate to open the upper surface of the shade.

Embodiments The configuration of this invention will be further explained based on illustrated embodiments.

In Figure 2, 1 is the desk body, 2 is its top plate 3
A bookshelf 4 installed vertically in the upper rear part is a light fixture attached to the lower surface of a shelf board 5 of an appropriate height and can be taken out and put in freely.

As shown in FIGS. 1 and 4, the light fixture 4 includes a box-shaped base 6 made of a thin iron plate, a fluorescent light 7 horizontally mounted on the front part of the base 6, and a fluorescent light 7 mounted horizontally on the front side of the box-shaped base 6 made of a thin iron plate. It consists of a shade 8 made of extruded synthetic resin material that covers the entire length, and end caps 9 made of synthetic resin fitted onto both ends of the base 6 and the shade 8. As shown in FIGS. 4 and 6, the lamp 4 is attached to the side plate 11 of the bookshelf 2 via the mounting plate 12 in the longitudinal guide groove 10 provided on the outer surface of the end cap 9 at both ends. Each pair of attached rollers 13 is fitted and supported so as to be slidable back and forth. In addition, in order to move the lamp 4 back and forth while always keeping it parallel to the shelf board 5, as shown in FIG. One end of each of them is pivotally attached to the mounting frame 15 on the lower surface side of the shelf board 5 through a horizontally long hole 16 with a mounting screw 17, and the other end is connected to the lamp 4 with a mounting screw 19 through the same long hole 18.
It is pivotally mounted on the upper surface of the box-shaped base 6. Therefore, the light fixture 4 can be pulled out in its entirety forward or stored on the bottom side of the shelf board while always maintaining a parallel state by pulling or pushing any one part of the light fixture toward the front. It's summery.

By the way, the shade 8 has a top wall that is
It is formed in the shape of a front-down step by an alternating arrangement of horizontal portions 8a and vertical portions 8b, and a convex portion 8c with a substantially circular cross section that protrudes forward is formed at the lower part of the front wall extending downward from the horizontal portion at the frontmost end. The lamp 4 can be easily inserted and removed by grasping the convex portion 8c or by placing a fingertip on the underside of the convex portion 8c. Further, the horizontal portion 8a of the step-like upper wall is formed as a milky white or other appropriate color or a transparent transparent portion, while the vertical portion 8b itself is formed opaque or is formed with an opaque film 20.
By adhering or painting a material or paint, it is formed in a non-transparent area. The entire front wall is made of an opaque material and is formed in a non-transparent portion. However, it is also permissible for the upper and lower ends of the front wall to be formed into milky white translucent translucent parts.

As mentioned above, the shade 8 has a light-transmitting part limited to the horizontal part 8a of the stepped upper wall, so that the light from the fluorescent lamp 7 is only exposed to the outside within the range of the angle shown by θ in FIG. In particular, there is almost no irradiation towards the front.

A space between the lower surface of the front edge of the shelf board 5 and the front end of the shade 8 of the lamp 4 is covered by a shielding plate 21. The shielding plate 21 is made of an extruded material made of opaque synthetic resin, and a mounting part 23 is formed in series at the upper end via a hinge part 22 made of soft resin. It is attached to the bottom of the front end. In this installed state, the light fixture 4 whose lower end is positioned in the retracted storage state
It is designed to slightly cover the upper part of the front wall of the shade 8. Therefore, as the lamp 4 is pulled forward, the shielding plate 21 is guided by the upper surface of the end cap 9 that follows the slope of its upper wall and is flipped upward, as shown by the chain line in FIG. The upper surface of the shade 8 can be gradually opened to the outside.

However, the shielding plate 21 may be configured to be interlocked with the back and forth movement of the lamp 4 via an interlocking link mechanism or the like.

Functions and Effects of the Invention Based on the fact that the illuminated desk of this invention has the above-mentioned configuration, it exhibits the following unique functions and effects.

When the lamp 4 is pulled out to the front of the shelf board 5, light from the fluorescent lamp 7 is radiated upward from the horizontal portion 8a of the upper wall that extends over the entire length of the shade. In addition, the upper wall is formed in a slope that slopes downward toward the front, and the light is transmitted only through the horizontal portion 8a, so that the irradiation range of the light is indicated by θ in FIG. so that you can get into a wide-angle state. Therefore, by pulling out the lamp 4, a wide area of the room can be brightly illuminated by the reflection from the ceiling. Therefore, when studying at the study desk, there is no need to turn on the room light, which can save electricity.

Further, the degree of illumination in the room described above can be arbitrarily adjusted by changing the open area of the upper wall above the shade 8 by the shielding plate 21 depending on the degree to which the lamp 4 is pulled out. Therefore, the relative relationship between the illuminance on the desk top surface and the brightness in the room can be adjusted as desired, and it is possible to achieve good harmony between the two.

The upper wall of the lamp 4 has a step-like shape, and its vertical portion 8b is formed as a non-transparent portion, so that it blocks light emitted toward the front. Therefore, the light of the fluorescent lamp is not directly irradiated onto the face of the person studying at the desk, and therefore, the person studying at the desk is not affected by glare.
