Description

  The present invention relates to a cover body and a file for binding paper sheets.

  Conventionally, various files have been proposed in which the thickness dimension of the cover sheet can be arbitrarily adjusted by adjusting the effective width dimension at which the spine cover is exposed according to the thickness dimension of the sheets to be bound.

  For example, a technique for pre-engaging a back cover with a front cover or a back cover in advance has been disclosed (for example, refer to Patent Document 1). In each case, the engagement can be released according to the thickness of the sheet bundle to be bound.

  However, when the above file is taken out in a state where it is arranged on a bookshelf without a gap, an operation of hooking a finger or the like on the back side of the back cover of the normal cover body and moving it forward is performed. However, when such an operation is performed on a file having such a cover body, the association between the back cover and the front cover or the back cover is released, and the back cover is displaced from the front cover or the back cover and cannot be taken out well. When it is taken out, it may happen that the back cover is pulled out from the front cover or the back cover, the back cover is exposed, and the effective width dimension becomes unnecessarily large.

An engaging portion that can be released and allows relative movement between the back cover and the front cover or the back cover is provided on at least one of the back cover, the front cover, and the back cover. It is characterized by. A file according to the present invention includes the above-mentioned cover body and a binding tool.

  In such a case, since the engaging portion is engaged with the back cover and the front cover or the back cover in the closed state accommodated in a bookshelf or the like, only the back cover is gripped when taking out the cover body. Even when pulled, it is possible to effectively prevent the back cover from being displaced or removed from the front cover or the back cover.

  In order to realize the engagement portion with a simple configuration, the engagement portion is provided with an engagement claw provided on either the front cover or the back cover, and the engagement claw provided on the spine cover. It is desirable to have engagement holes that can be combined.

  In addition, attaching the label to the outside of the back cover makes it easy to grasp the contents of the usages closed on the cover, but in order to suitably attach this label, the label is accommodated outside the back cover. If the label holder is provided with a covering surface portion interposed between the engaging portion and the label, the interference between the engaging portion and the label is avoided, and the label position is obtained. Regardless, the effective size of the back sheet can be easily changed.

  If a plurality of engagement portions are provided in the vertical direction or the horizontal direction of the spine cover, a more stable engagement state can be ensured.
