Problems solved by technology

[0006] However, in order to reliably transmit the operating force in the binding direction of only one of the binding rings to the other binding ring as described above, and to reliably apply the required force when the joint parts of the binding rings are engaged with each other, the current situation is that The blanks and / or shapes that make up the binder are naturally limited

Embodiment Construction

[0053] Refer below Figure 1 to Figure 13 One embodiment of the present invention will be described.

[0054] This embodiment is an aspect in which the present invention is applied to a folder F and a binding tool G attached to the spine H2 of the cover H of the folder F. FIG.

[0055] Folder F includes a cover H having a front cover H1, a spine H2, and a back cover H3. The use direction of the folder F is clearly set by unillustrated printing and / or a seal applied to the cover H. As shown in FIG.

[0056] The binding appliance G comprises: a base 1, which is supported by a first connecting plate 11 and a second connecting plate 12 butted against each other; The first ring constituting members 31, 51 and the second ring constituting members 32, 52 supported by the second connecting plate 12 can also be closed by an operating force applied to one of the binding rings 3, 5 in the closing direction. Close the other binding ring 5.

[0057] In other words, the binding tool G i...

Abstract

The invention provides a binding tool which enables engaging parts of binding rings to be engaged reliably even with a smaller operation force and a folder with the binding tool. The binding tool is characterized in that through the operation force applied in the closing direction of one binding ring in the plurality of binding rings at the opening positions, another binding ring can be closed. A first connecting plate is made of resin and is integrally formed with first ring forming members and a second connecting plate is made of resin and is integrally formed with second ring forming members. An elastic force application unit applies force to the binding rings in the opening direction; when the application force is overcome and the rings are closed, the engaging parts at the top ends of the first ring forming members and the second ring forming members are engaged and the binding rings are kept at closing positions.

Description

technical field [0001] The present invention relates to a binding tool for binding documents and the like, and a folder to which the binding tool is applied. Background technique [0002] In the past, as this binding appliance known binding appliance (for example, refer to patent document 1 and patent document 2) that comprises following member: install the base that the first connecting plate that butts with each other and the second connecting plate form; And a pair of The binding rings each include a first ring constituting member supported by the first connecting plate and a second ring constituting member supported by the second connecting plate. [0003] The binding rings in this binding tool are elastically biased in an opening direction with uniform force by a leaf spring or the like disposed between the pair of binding rings. And, by overcoming this elastic urging force, the binding ring in the open position is operated in the closing direction, and the joint parts...
