Description

  The present invention relates to a desk structure used in a work space such as an office.

As a desk used in the office space, for example, a sleeve box having left and right directions by attaching a bracket on the back is connected with a connecting rod to form a base portion, and a top plate is placed on the top surface. What fixed and comprised the desk is well-known (patent document 1).
According to this, there is an advantage that the member can be shared, but since the connecting collar and the sleeve box are connected by the bracket protruding from the back of the sleeve box, a gap is generated by the protrusion of the bracket, and the appearance There was a problem with the above appearance, and the strength was not always sufficient.
Further, since the desk has a complete structure, when it is desired to use a plurality of desks side by side, the desks are simply used side by side.
In this case, two support legs are arranged side by side at the end portions of the adjacent desks, and the structure is wasted and the appearance is not preferable.
On the other hand, when it is desired to use a plurality of desks side by side, there has been proposed a structure in which a support leg is shared at a connecting portion with an adjacent desk (Patent Document 2).
This proposal can eliminate the structural waste of the connecting portion and has a good appearance.
However, since the desk is configured only by connecting the support legs and the top plate with brackets, the strength is not always sufficient.
