Embodiment Construction

[0034] Next, one embodiment of the present invention will be described with reference to the drawings.

[0035] The folder F that has used binding leg 1 of the present invention, as Fig. 1 and figure 2 As shown, it has a clamping surface 2, an elongated plate-shaped pressing plate portion 3 formed by folding one end of the clamping surface 2 inward, and a clamp formed by bending from the pressing plate portion 3 to the direction opposite to the clamping surface 2. The back 4, the clip bottom 5 separated from the clip surface 2, and the elongated plate-shaped substrate portion 6 formed by folding one end of the clip bottom 5 inward are in a shape extending along the length direction of the substrate portion 6. The above-mentioned binding leg 1 can be passed through the binding leg stop 7 which is formed in a fastening manner. In addition, as shown in Figure 1 and figure 2 As shown, the paper P is represented by a phantom line.

Abstract

The present invention is a binding leg for a file that seeks both ease of use and prevention of damage to sheets. The binding leg body is formed by extending from the base end portion of the binding leg, and a bent portion (11a) is formed on the binding leg body, and the bent portion is bent so that the front end portion can be deflected in the thickness direction. At the same time of the structure, the bending portion (11a) is provided with a flexible portion (111) having a thick portion (111a) and a thin portion (111b), and at least both side ends of the flexible portion (111) are placed together. The thick part (111a) is formed in the part, the thin part (111b) which is thinner than the thick part (111a) is provided adjacent to the thick part (111a) in the width direction, and the thick part (111a) is further formed. The part (111a) and the thin part (111b) are arranged so as to form the engaging groove (11x) and the vertical groove (11y) as recessed parts in the thickness direction to form the flexible part (111).

Description

technical field [0001] The present invention relates to a binding leg applied to a folder for refillably holding papers. Background technique [0002] Conventionally, most of the binding legs used together with the binder clips of file folders have a flat shape with grooves provided at predetermined intervals on one side thereof. [0003] However, such a binding leg has a problem that the shape of the edge becomes sharp, and the paper or the like is easily damaged due to contact with the edge. [0004] In order to simply solve this problem, it is conceivable to increase the thickness of the binding legs and make the shape of the edges less sharp. [0005] However, simply making the binding legs thicker than the conventional flat shape has new disadvantages such as that the binding legs are difficult to bend when replacing the papers held in the folder, and ease of use is reduced. Contents of the invention [0006] The object of the present invention is to solve the above...
