Problems solved by technology

In addition, the following situation can also be assumed: if the above-mentioned separation occurs at the end, not only the base will be separated from the pair of binding rod members, but also the different parts attached to them will be separated, and then only the base and the When the binding rod parts are assembled, different parts will still fall off, and the original function as a binding tool cannot be reproduced

Embodiment Construction

[0054] One embodiment of the present invention will be described with reference to the drawings. Figure 1 to Figure 16 The shown binding tool T of this embodiment is what is called a so-called ring binding tool provided with the several binding rod elements 12 and 22 which can be opened and closed. These binding rod elements 12 and 22 are configured to be able to bind the sheets S through the binding holes punched in the sheets S in advance.

[0055] In particular, if figure 1 As shown, by binding the paper sheets S such as multiple sheets of paper in the middle of the notebook and / or replacement pages (further front cover and / or back cover) of the transparent folder, it is possible to meet the requirements as a ring. Notebook use. This ring-shaped notebook can be set in a folio state in which pages are opened at an angle of 180°.

[0056]The constituent elements of the binding tool T of the present embodiment are: a first binding rod member 1 and a second binding rod memb...

Abstract

The invention provides a binding tool with uneasy deviation between a pair of binding rod components and a base seat, and capable of maintaining stable actions. The binding tool comprises a pair of binding rod components having binding rod elements capable of rotating surrounding a preset axis to close and open, a base seat selectively choosing a binding position and opening position relatively moving according to the pair of binding rod components in an axis direction, an elastic component applying elasticity to the base seat in the binding or opening position in a middle position of the axis direction of the base seat, and a separation blocking part arranged on the base seat or the pair of binding rod components to block two ends of the pair of binding rod components to be separated from two ends of the base seat in the axis direction within an action range from the binding position to the opening position.

Description

technical field [0001] The present invention relates to a binding tool capable of binding and fixing paper sheets. Background technique [0002] A ring binder capable of binding and fixing sheets of loose-leaf and / or replacement pages of transparent folders is known (see, for example, Patent Document 1 below). In this binding tool, the ring-shaped binding rod element can be opened and closed by turning, and the paper sheets can be replaced arbitrarily. [0003] In most conventional binding tools, hook claws are formed at the top ends of partially arc-shaped paired binding rod elements, and the engagement of the hook claws prevents the separation of the two binding rod elements and maintains the binding rods in a closed state. . Therefore, in order to release the binding rod, it is necessary to displace the one binding rod element relative to the other binding rod element in the axial direction to cancel the engagement of the claws. In particular, in a binding tool in whic...
