Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a learning desk, and more specifically, it is attached to a bookshelf arranged on the top plate of the learning desk and can be moved back and forth, and from either the left or right side. The present invention also relates to a lighting device that can be pivotally pulled out to the front side.

[0002]

2. Description of the Related Art Conventionally, various types of lighting devices have been provided which are attached to book shelves arranged on the top plate of a learning desk. For example, as disclosed in Japanese Utility Model Publication No. S58-10961, one end of an illuminator is rotatably attached to a lower surface of a shelf of a bookcase by a vertical pivot, and the pivot is attached to the other end of the illuminator. There is provided an illumination device having a structure in which an arc-shaped guide groove having a center is formed, and the guide groove is slidably supported by a guide member provided on a side plate of a bookcase.

Further, as disclosed in Japanese Utility Model Publication No. 61-3060, two rotating arms, each of which has its base end rotatably rotatably mounted on the lower surface of the shelf plate at a predetermined interval, are provided. The guide grooves provided in substantially the entire length of each arm in the longitudinal direction are arranged in a substantially X-shaped crossed arrangement in a plan view so as to vertically oppose each other, and a diameter-expanding protrusion that can be slidably fitted and locked in the guide grooves in the longitudinal direction of the rotating arm Provided is an illumination device in which both upper and lower rotating arms are connected and supported at the intersecting portion by using a slider having upper and lower portions, and the tip ends of the both rotating arms are pivotally attached to an illuminating tool. Has been done.

[0004]

However, in the rotating mechanism described in the former publication, the side from which the end of the illuminator can be pulled out is limited to one of the left and right sides, and is commonly used as a right-handed or left-handed one. I can't. Further, in the latter rotating mechanism described in the publication, both sides of the illuminator can be pulled out to the front side, respectively, although it can be shared as a right-handed person and a left-handed person in the sense of preventing darkness of the hand,
Since the end of the lighting device opposite to the pull-out side moves to the rear of the shelf, it does not contribute much to the improvement of the illuminance at the front of the desk top.

In view of the above-mentioned situation, the present invention is to solve the problem by providing a lighting device on a bookshelf arranged on the top plate of a learning desk so as to be slidable in the depth direction, and arranging the lighting device on either side. The point is to provide a lighting device for a learning desk that can be pivotally pulled out from.

[0006]

In order to solve the above-mentioned problems, the present invention is an illuminating device attached to a bookshelf arranged on a top plate of a learning desk, which is located between both side plates of the bookshelf. The sub-support with the lighting fixture attached to the main support that is slidable in the depth direction is linked by a bidirectional rotation mechanism that allows one of both sides to be rotationally drawn out with the other as the stationary center of rotation and the other toward the front side. The lighting device for the learning desk was constructed.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The illumination device for a learning desk according to the present invention is provided with a main support slidably in the depth direction between both side plates of a bookshelf arranged on the top plate of the learning desk. The sub-support with the lighting fixture attached is linked by a bidirectional rotation mechanism that allows one of both sides to be fixed as the center of rotation and the other to be rotated and pulled out to the front side. It can be moved to the side, that is, the lighting fixture can be moved in parallel to the front side to move the high illumination range to the front part of the tabletop, so that the front part of the tabletop becomes bright as a whole. Further, in this state, the sub-support, that is, one end of the illuminator is pivotally pulled out to the front side with respect to the main support, so that it is possible to prevent the darkness of the hand. Further, even when a wagon desk is arranged beside the learning desk, by rotating and pulling out the end part of the lighting device on the side opposite to the wagon desk, a high illuminance range can be obtained due to the directionality of light of the lighting device. It is possible to bring it closer to the wagon desk and effectively illuminate the upper surface of the wagon desk.

Here, the bidirectional rotation mechanism forms an upper space between the upper plate and the lower plate on the main support, and forms a space open to the front between the upper plate and the lower plate. An intermediate plate formed on the rear portion of the support is arranged in the space, and an upper link plate and a lower link plate of the same length are respectively provided between the upper plate and the intermediate plate and between the intermediate plate and the lower plate. It is arranged in the lateral direction, and the ends of the upper plate and the upper link plate are pivotally attached at the left and right sides, and the ends of the intermediate plate and the lower link plate are pivotally attached, and the ends of the upper link plate at the left and right other sides. If the end portion of the lower link plate and the lower plate are pivotally attached to each other and the intermediate plate and the respective pivot points on both left and right sides are set at the same position vertically, The pivot point of one of the left and right ends can be used as the fixed center of rotation to rotate and pull out the other end so that darkness does not occur in the high illumination range. It is possible to move to the front of the desk top panel.

The illuminating device for a learning desk according to the present invention as described above is an illuminating device attached to a bookshelf arranged on the top plate of the learning desk, and is located between both side plates of the bookshelf. A sub-support with a lighting fixture attached to a main support that is slidable in one direction is linked by a bidirectional rotation mechanism that allows one of both side parts to be fixed as a rotation center and the other to be pulled out toward the front side. Therefore, it is possible to move the illuminator parallel to the bookcase and move the high illuminance range to the front of the desk top to make the front of the desk top brighter overall. In this state, the sub-support, that is, one end of the illuminator is pivotally pulled out to the main support with respect to the main support, so that the darkness of the hand can be prevented. Further, even when a wagon desk is arranged beside the learning desk, by rotating and pulling out the end part of the lighting device on the side opposite to the wagon desk, a high illuminance range can be obtained due to the directionality of light of the lighting device. It is possible to bring it closer to the wagon desk and effectively illuminate the upper surface of the wagon desk.

Further, as the bidirectional rotation mechanism, an upper plate and a lower plate are vertically separated from each other on the main support, and a space which is open to the front is formed between the upper plate and the lower plate. An intermediate plate formed on the rear part of the body is arranged in the space, and an upper link plate and a lower link plate of the same length are laterally provided between the upper plate and the intermediate plate and between the intermediate plate and the lower plate, respectively. The left and right sides, the upper plate and the upper link plate end portions are pivotally attached, and the intermediate plate and the lower link plate end portion are pivotally attached, and the left and right other side portions are the upper link plate end portions. And an intermediate plate are pivotally attached to each other, and the lower link plate is pivotally attached to the end portion of the lower link plate, and the pivot points on the left and right sides are set to the same position in the vertical direction. The pivot point of one end can be used as a stationary center of rotation for the other end to be smoothly rotated, and the range of high illuminance is shaded. As it does not cause can be optimally moved to the front of the desk top panel.
