Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sandwiching mechanism for files and the like. Specifically, a vertically long U-shaped sandwiching piece is made on a thin base plate made of hard synthetic resin or the like, and a fold is provided in this sandwiching piece to make a flexible material. The present invention relates to a sandwiching mechanism that can sandwich a paper sheet by using the.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, various kinds of pinching mechanisms for holding a file, such as a device for holding a paper sheet by using a coil spring, or a device in which a hole is provided in the paper sheet and the paper sheet is bound by using the hole, have been provided. .

[0003]

[Problems to be solved by the device]

 However, since these holding mechanisms use metal coil springs and holding metal fittings, the number of manufacturing processes is large, not only the cost is high, but also the paper cannot be easily sandwiched or removed. The present invention forms a vertically long U-shaped gripping piece on a thin base plate made of a flexible material such as hard synthetic resin, and uses the flexibility of this gripping piece to easily grip or remove paper or the like. It is an object of the present invention to provide a sandwiching mechanism for files and the like that can be used.

[0004]

[Means for Solving the Problems]

 To achieve the above object, the present invention forms a U-shaped holding piece 1 by providing a vertically long U-shaped slit on a thin base plate A made of a flexible material such as hard synthetic resin. A central folding curve 2 is provided along the vertical center line of the sandwiching piece 1, and the upper part of the central folding line 2 is bifurcated so that the branched tip reaches the tip of the U-shaped slit. Folding curves 3 and 3a are provided, and a cutout portion 5 is provided on the base plate A near the lower end of the sandwiching piece 1 so that the sandwiching piece 1 is formed in a letter shape from the central folding curve 2 and the upper folding curves 3 and 3a. By bending, both upper ends of the U-shaped slits are slightly extended inward to provide slits 4 and 4a.

[0005]

[Action]

 When the present invention configured as described above is actually used, as shown in FIG. 3, the paper 6 is inserted between the lower portion 1a of the sandwiching piece 1 and the base plate A, but the paper 6 is sandwiched between the base plate A and the base plate A. Insert it to the position where it is securely clamped by the piece 1. When you want to remove multiple sheets of paper sandwiched, you can remove the desired paper regardless of the top and bottom by pulling it with your fingers.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG. 1. Reference numeral A in the drawing is a thin base plate made of a flexible material such as hard synthetic resin. is there. Reference numeral 1 denotes a U-shaped holding piece formed by providing a vertically long U-shaped slit at an appropriate position of the base plate A, and the holding piece holds the paper. Reference numeral 2 is a central folding curve provided along the vertical center line of the sandwiching piece 1. The upper portion of this central folding curve 2 is bifurcated to provide upper folding curves 3 and 3a, which can be bent from each folding curve. As shown in FIG. 2, the holding piece 1 is formed in a V-shape, and the upper folding curves 3 and 3a, which are branched like a Y-shape, are installed so that the tips reach both upper ends of the U-shaped slit. Has been. The holding piece 1 bent in the shape of a line from each of the folding curves 2, 3, 3a does not bend due to being bent, and the force for holding the paper or the like becomes stronger. Reference numerals 4 and 4a are slits formed by cutting the tips of U-shaped slits inward, and by providing the slits 4 and 4a, the upper folding curves 3 and 3a can be bent accurately. Reference numeral 5 denotes a cutout portion obtained by cutting out the vicinity of the tip 1 of the sandwiching piece 1, and the provision of the cutout portion 5 makes it easy to insert paper to be sandwiched. The base plate A is not limited to a specific shape and can be formed into various shapes as needed, and is not limited to a file and can be widely applied.

[0007]

[Effect of device]

 Since the present invention is configured as described above, the paper sandwiched between the sandwiching piece 1 and the base plate A is securely sandwiched, and the sandwiched plurality of papers can be removed by the required number. Further, even if one paper in the middle of the sandwiched plural papers is removed, the other papers are still sandwiched as they are. The sandwiching mechanism of the present invention can be provided at low cost because it can be manufactured by a simple process of punching a flexible thin plate with a press or the like.
