Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a type of file in which the ends of sheets to be bound are bound together by means of clamping plates.

(Prior Art) Conventionally, a so-called Z-type file exists as a type of file in which the ends of sheets to be bound are bound using sandwich plates. However, since the file clamping plate clamps the center part of the side edge of the paper sheet over a fairly long distance and width, the characters etc. marked on the side edge of the paper sheet are hidden. There are drawbacks. In addition, some long sheets of paper with folded edges do not want the folded edges to be strongly folded by the pressure of the clamping plate, and such paper sheets cannot be folded using the conventional clamping plate type. It was hot.

(Problems to be Solved by the Invention) The purpose of the invention is to provide a novel file which can be created by fixing only the upper and lower side edges of the paper sheets to be bound, and which can solve the above-mentioned problems. There is a particular thing.

(Means for Solving the Problems) In order to achieve the object, the present invention includes a rotatable presser lever having a locking protrusion, and a presser lever that is connected to the presser lever by a torsion coil spring and is the same as the presser lever. A clamping plate that can be rotated in any direction to raise and lower the clamping plate, and an upright plate that has a locking hole that can be engaged with the locking protrusion of the presser lever when the clamping plate is pressed against the cover etc. by rotating the presser lever. A pair of binding devices, each consisting of a fixing plate and a fixing plate, are installed at both upper and lower end positions near the spine of the inner surface of the cover so that the presser levers can rotate in the lateral direction along the upper or lower edge of the cover, respectively. This provides a file featuring the following.

(Embodiment and operation) An embodiment of the present invention shown in the drawings will be described below along with its operation.

A pair of binding devices 1 and 1' are provided, and their structure is as follows. First, the shaft support plates 2 and 2' are stood up and opposed to each other at a required distance apart, and the shaft support plates 2, 2'
2' supports both ends of a shaft 4 having a torsion coil spring 3 attached to its outer periphery, and this shaft support plate 2,
A fixing plate 5, which has a width substantially the same as the interval 2', has an upright plate part 5a on one inner edge thereof, and has a locking hole 5b at the tip of the upright plate part 5a is attached to the shaft support plate 2. ，
It is disposed perpendicularly to the shaft 4 supported by the shaft 2', that is, on one side of the shaft support plates 2, 2' (the shaft support plates 2, 2' and the fixing plate 5 are integrally molded). ), one end of the torsion coil spring 3 is connected to a presser lever 6 which is rotatable in the vertical direction with respect to the shaft 4 around the outer circumference of the torsion coil spring 3 and has a locking protrusion 6a formed on the outer surface of the inner side wall thereof, The other end of the coil spring 3 passes through the notch 5c of the upright plate portion 5a of the fixed plate 5, and rotates in the same direction as the rotational direction of the presser lever 6 at a position outside the upright plate portion 5a. It is configured to be connected to the plate 7. The pair of binding devices 1 and 1' are sandwiched between upper and lower end positions near the spine 8a on the inner surface of the cover 8 so that the presser levers 6 can rotate in the lateral direction along the upper edge or lower edge of the cover 8, respectively. It is installed by riveting the fixing plate 5 to the cover 8 with the mounting plate 7 facing inside.

The method of operating this binding device 1, 1' is as follows. First, put the presser lever 6 down on the opposite side of the fixing plate 5, put the clamping plate 7 in the upright state (see the binding device 1 at the bottom of the drawing), and place the paper to be stapled in the position where the clamping plate contacts the cover 8. Place the upper and lower ends of one side edge of the leaf, that is, the corners. Next, the presser lever 6 is twisted to rotate the outer periphery of the coiled spring 3 by 180 degrees to deform the torsion coiled spring 3 and lock the clamping plate 7 in a state in which it is pressed against the sheets to be stapled by the spring pressure. The protrusion 6a is engaged with the locking hole 5b of the upright plate portion 5a of the fixed plate 5 (see the binding device 1' at the top of the drawing). This completes the binding process. To cancel the binding, just perform the reverse operation.

(Effects of the invention) The present invention has the above-mentioned structure and function, and is achieved by pinching only the upper and lower ends of the paper sheets to be bound, without pinching the center of one side edge of the paper sheets. Since it can be used as a file, there is no need to hide the characters printed on the side edges of the paper sheet, and even if the folded part is on the side edge of the paper sheet, a strong fold line can be created at the folded part by pressing with the clamping plate. You will also be able to avoid things that could cause you to get stuck. Note that by rotating the presser lever and the clamping plate in the direction along the upper and lower edges of the cover, the space between the two binding devices does not become narrow.
