Title:
BINDING TOOL, EXTENSION PIPE, AND FILE
Document Type and Number:
WIPO Patent Application WO/2008/018294
Kind Code:
A1
Abstract:
Provided is a new, useful binding tool, which has a structure useful for handling with a back width being enlarged from that of an ordinary state and which is effectively prevented from having a winding lever weakened at the widening time. The binding tool is of a pipe type, in which a pipe (53) protruded from one of paired holding members (51) and a bar (54) protruded from the other are fitted on each other to form a binding lever (5x) having a fitting depth matching the back width. In a manner to cover the protruded portions of the bar (54) from the existing pipe (53) in the enlarged back width, an extension pipe (55) is fitted in the existing pipe (53) thereby to extend the binding lever (5x).
