Description

  The present invention relates to an attachment structure for detachably attaching a binding tool for binding a large number of sheets together to a cover panel.

  In a file that binds a large number of sheets together, it is necessary to remove the metal binding tool from the cover panel made of combustible material and separate it according to the material at the time of disposal. The binding tool can be easily removed from the cover panel. A removable configuration is desired. In addition, even when an old cover panel is replaced and used, a configuration in which a binding tool can be easily attached to and detached from the cover panel is desired.

However, in order to attach the binding tool to the cover panel in a detachable manner, it is easy to combine them with a clip that penetrates both. For example, the binding tool is elastically inserted through attachment holes provided in the binding tool and the cover panel. The structure using the clip provided with the protrusion which engages is known (refer patent document 1). In addition, a configuration using a clip that joins a binding tool and a cover panel by a rotating operation is known (see Patent Document 2).
Japanese Patent No. 3409963 JP-A-9-142077

  However, in the configuration described in Patent Document 1, the operation of attaching the binding tool to the cover panel can be performed relatively easily, but when the binding tool is removed from the cover panel, the protrusion is inclined by the operating rod. In this case, it is necessary to continuously remove the clip, and it is necessary to continue to apply force to the operation rod until the clip is detached. Further, in the configuration described in Patent Document 2, it is necessary to insert and rotate a clip in accordance with the shape of the mounting hole at the time of mounting, and a configuration that can further simplify the mounting operation is desired.
