Problems solved by technology

[0007] In addition, the edge of the side opposite to the binding side of the plurality of documents bound to the binder, in the state where the protruding amount of the document located in the middle of the thickness direction of the document becomes the largest, has a large mountain-shaped side view, so this becomes The main reason why it is difficult to hook the fingertip to the side edge and to turn the page of the document

no. 1 Embodiment approach

[0046] exist figure 1 , shows a schematic perspective view of main parts when the binder according to the first embodiment is applied to a document file. figure 2 In , a schematic perspective view of the binder is shown. In these figures, the folder 10 is configured to include: a cover body 14 including a front cover 12 and a back cover 13 connected via a spine 11 in the middle; and a binder 15 attached to the inner surface of the spine 11 . Here, elongated holes 12A and 13A for accommodating a part of the binder 15 are formed linearly along the width direction of the covers on the surfaces of the front cover 12 and the back cover 13 close to the back cover 11 .

[0047] The binding tool 15 is composed of: a base body 18 extending in the vertical (length) direction of the backseal 11 and fixed to the inner surface of the backseal 11 via rivets 17, 17; a pair of first binding members 19, 19, which are respectively supported on the end of the cover 12 side of the base 18; 19...

no. 2 Embodiment approach

[0060] Next, for the second embodiment of the present invention, while referring to Figure 6 to Figure 10 while explaining. In addition, in the following description, the same code|symbol is used for the part which is the same as or equivalent to 1st Embodiment, and description is abbreviate|omitted or simplified as needed.

[0061] The second embodiment is characterized in that the standing shaft portion 32 is formed in an arc shape with an inner radius of 25 mm, and is connected to a curved shaft portion 33 with an inner radius of 11 mm. Therefore, in the second embodiment, at the closed loop forming position, the maximum width W1 of the first and second binding members 19 and 20 is set to 31.4 mm, the width W2 on the inner peripheral side is set to 26 mm, and the total length L is set to 31.4 mm. Set to 34.7mm. The width W3 of the back seal 11 was set to 29.4 mm. In addition, since the erected shaft portion 32 of the second embodiment is not linear, the boundary between...

Abstract

The present invention provides a bookbinding member and a file folder capable of restraining dimension of setting first and second bookbinding components at a closed-loop forming position along a width direction. The first and second bookbinding components (19, 20) may be rotatingly supported by a basal body (18) arranged on a cover body (14). The bookbinding components (19, 20) are formed into a closed loop by jointing top end parts, and files P may be settled by disconnecting the closed loop. The first and second bookbinding components (19, 20) includes a stand shaft part (32) facing upwards from the basal body (18) in a state of forming the closed loop; and a bending shaft part (20) extending inwards from the top side of the stand shaft part (32) to the top end part facing to the bookbinding components; the stand shaft part (32) is of a straight line shape, or of a circular arc shape that the radius of the inner circle is more than 25mm.

Description

technical field [0001] The present invention relates to a binder (binder) and a document file. More specifically, it relates to a device capable of forming a closed loop by joining the distal ends of shaft-shaped first and second binding members, and releasing the first and second binding members. 2. A binder that opens a closed loop by joining the binding members to add and subtract files, and a file that integrates the binder with a cover body. Background technique [0002] A binder used in a ring folder (ring file) etc. includes: a base body of a predetermined length along the length direction of the spine of the folder; 1 binding member; and a second binding member located on the opposite side of these first binding members and provided so as to engage with the tip end of the first binding member. The bases of the first and second binding members are rotatably supported in the base, whereby the first and second binding members can be positioned at a closed-loop forming ...
