Description

  The present invention relates to a support device for an attachment member in a shelf device, and more particularly to a support device for detachably attaching an attachment member such as a drawer or a shelf board between side plates and partition plates.

  Generally, in a shelf device such as a desktop shelf placed on the back of the top of the learning desk or a book shelf used side by side at the back or side of the learning desk, both side plates and the back constituting the shelf are used. When attaching attachments such as a main stand or a shelf board in a space formed with a plate, the pin dowels and wire dowels are detachably provided on the side surfaces of the side plate and the partition plate, and the attachment members are attached to the dowels. It is well known to support both sides of the.

  Further, in Patent Document 1, a partition plate is fixed to the center of both side plates of the shelf device, and the main stand and the shelf plate are attached and detached with support members detachably attached to the inner surface side of both side plates and the both side surfaces of the partition plate. When supporting it as possible, the support tool is a line dowel or a plurality of pin dowels extending in the depth direction, and the line dowels attached substantially horizontally to the locking holes formed in the side plate and the partition plate or attached in a horizontal arrangement. Further, there is disclosed a structure in which support grooves that are open to the rear for slidably receiving a plurality of pin dowels are formed on both sides of the main stand and the shelf board.

However, simply mounting both side portions of the attachment member on the pin dowel or the wire dowel may cause the attachment member to move forward and drop unexpectedly. For this reason, in the case of a pin dowel, an engagement portion that receives the pin dowel may be provided on the lower surface of the side portion of the accessory member. However, in a drawer unit with a drawer integrated on the bottom surface of the shelf board or a drawer provided in the front open box, a rear open support groove that simply accepts a wire dowel is formed on the side of the unit. However, there is a case where the drawer moves unexpectedly during the drawer operation. In this case, it is necessary to operate the drawer while pressing the unit with one hand, which causes a problem in operability.
