Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a learning desk that can change the usage pattern according to the user, the place of use, the purpose of use, or the growth of the body.

[0002]

2. Description of the Related Art In a conventional learning desk, a sleeve cabinet is fixed to one of the left and right sides of a top plate, and legs are provided on the other side. That is, since the width between the leg part and the sleeve cabinet is constant, in the upper grades (when the physique becomes larger), the circumference of the legs becomes narrower, and there is a problem that the usability is deteriorated.
In particular, when the leg side is placed in contact with the wall surface, the elbow of the user comes into contact with the wall surface, so in order to avoid this, the upper half of the body is twisted to the sleeve cabinet side, which is preferable. There wasn't. Further, since the sleeve cabinet is fixed, the elbow may protrude from the top plate depending on the user's skillful hand, which may hinder the work.

In order to solve these problems, legs are provided at the left and right ends of a top plate having a center drawer on the lower surface, and a movable sleeve cabinet having casters on the lower surface is placed in and out of a space below the center drawer. Flexible ones have been proposed. When a wide working surface is secured on the top plate, the movable sleeve cabinet is pulled out to the outside of the legs to solve the narrowness around the legs when it grows up. Was used at either the left or right side of the space below the tabletop to match the installation location and the physical characteristics of the user.

However, in this case, since the sleeve cabinet is constructed lower by the height of the center drawer, it is not possible to secure a sufficient storage capacity for the sleeve cabinet. For this reason, a center drawer that is slidable in the left-right direction is provided on the bottom surface of the top plate through a drawer frame, and with this center drawer slid to either the left or right leg side, the end and the other Between the legs, it is possible to fit the upper part of the sleeve cabinet which has multiple casters on the lower surface and is movable,
The sleeve cabinets with a high height are now available.

However, in this case, when the sleeve cabinet is fitted in or pulled out, and further when the drawer frame is moved to the left or right by the center drawer drawer operation, the drawer frame or the front plate is moved to the side of the sleeve cabinet. It sometimes collided with and came into contact with the center drawer, or the drawer frame, or even the sleeve cabinet.

On the other hand, in a desk in which the sleeve cabinet is fixed to either the right or left side of the top plate, the height of the top plate is constant, so that it can be used by children with a small physique between the legs and the sleeve cabinet. A step board is placed in the room, and the height of the step board and the height of the chair are changed according to the growth of the child (when the user's physique is small, the height of the step board and the chair is increased). Even if the tabletop height is constant, the height position suitable for the user's physique can be obtained by placing the sole of the foot on the step board while seated on the chair and pulling the chair toward the desk side while floating the waist. I was trying to become.

However, since the step cabinet cannot be attached because the sleeve cabinet can be moved, when the children of lower grades who do not have a sufficient physical constitution use it, the sole of the foot is not attached to the floor surface and becomes unstable. However, it was impossible to pull the chair to the desk or to separate the chair from the desk when leaving the seat, and it was actually impossible for a child of a lower grade to use a desk having a movable sleeve cabinet. Also, when the movable sleeve cabinet is located outside the desk, the user sits down in the center of the top and uses the desk, so when using the center drawer installed on the bottom of the top, If you move the chair backwards and do not move your body,
I couldn't pull out the center drawer.
