The present invention relates to a desk that can be adjusted from a floor without permission to a plurality of levels, and a desk system that can be used in various ways.

[0002]

2. Description of the Related Art Conventionally, as desks for learning and offices, desks with a sleeve box such as a single-sleeve desk and a double-sleeve desk, and desks without a sleeve box have been provided. Of course, it is also configured with a top plate. The top plate is supported by columnar or plate-shaped legs, and particularly in the case of a sleeve box, the sleeve box also has a leg function.

Also, for use with a desk,
Various wagon desks with multiple drawers are offered. This wagon desk is used not only with a desk with a box but also as a desk without a sleeve box to form a form like a desk with a sleeve box,
In many cases, the wagon desk can be used by storing it under the desk or by using it under the desk.

Further, conventionally, various desks have been proposed which can effectively use the indoor space and can expand the work area according to the convenience of the user. For example, in the desk set described in Japanese Patent Laid-Open No. 10-286126, the side chest stored in the space below the top plate of the desk body is pulled out to the front if necessary, and the upper plate is used according to the desk top plate. By making it possible, it is possible to effectively utilize the indoor space. Further, in the learning desk described in Japanese Patent Laid-Open No. 10-57167, the sleeve cabinet housed in the space below the top plate is placed outside the desk leg according to the user, the place of use, etc. Then
The work area can be expanded.

[0005] In addition, the generally provided desk is a direction at the time of use in which the user sits down in a specific direction planned for this work, as represented by a desk for learning and an office desk. Due to its nature, the desk is generally placed next to a wall or a bookshelf.

[0006] However, the desk provided so far can change the width of the desk system by combining it with the wagon desk, but it does not change the width of the desk itself. Since the width of the desk system is changed depending on the placement of the desk,
The width of the desk and desk system can only be adjusted in two steps. Therefore, when a conventional desk or desk system is placed in the indoor space, a gap (dead space) may inevitably occur between the wall and other furniture (such as a bookshelf). For example, when arranging the desk or desk system, it is impossible to effectively use the indoor space unless the space is rigorously measured to secure the space for arrangement.

Also, the foot-holding space secured on the lower surface of the top plate of the desk can be adjusted only in two stages depending on the presence / absence of the wagon desk, and cannot be optimized in accordance with the growth of the user. .
