Description

  The present invention relates to a binding foot, and more particularly, to a binding foot that is used by being fixed to a cover for binding, for example, a document in which a binding hole is formed to a file binder.

To bind documents to file binders, for example, flat files (JIS
There is a binding tool having a binding foot used in S5505). The binding tool has a binding foot that is fixed to a binding margin portion provided between a cover and a back cover and is inserted into a binding hole of a binding object such as a note to bind the binding object. This binding foot is generally made of synthetic resin. However, if the object to be bound is stored for a long time in a state where it is bound to the binding foot, the binding foot is wrinkled in a bent state, and the binding foot does not return to the original upright state.
In addition, there is a binding foot using a coil spring. When this binding foot is bent and the binding object such as a note is bound by bending the coil spring, a gap is generated because the coil spring is bent, and the note or the like is placed in the gap. Sometimes, it may interfere with the removal of pinched notes.
Moreover, in order to attach such a coil spring to the binding margin of the cover of the file / binders, processing for attaching the binding margin to the root of the coil spring is required. However, since the coil spring is small, A lot of work is required in processing.
