Description

[Detailed Description of the Invention] The present invention relates to an improvement of a paper clip used for binding documents by pressing them with a pressure rod.

Conventionally, as this type of paper clip, for example, Utility Model No. 33-119
As shown in No. 16, a standing piece is formed at both ends and the back of the base, and two wire rods are bent downward in the center of the standing piece on one end of the standing piece. There was a paper clip to which the base of an elastic pressing member was pivotally attached, and the other end of the upright piece had a hooking portion that engaged with a hooking portion provided at the tip of the pressing rod.

However, since the press rod of this type of paper sandwich is elastic, when the press rod and the base are disengaged, the press rod springs up in the direction away from the base, causing the tip of the press rod to It was often dangerous to hit people in the face.

This phenomenon of springing up was particularly noticeable when taking out documents with many edges, and the handler had to take special care, which was extremely dangerous for first-time handlers.

In addition, with conventional press rods, the base is only pivoted to one end of the base, so when it comes time to bind documents, the arched center of the press rod comes into contact with the base. Because of this, it was a pain to have to use both hands to lift the push rod with one hand while holding the document in place with the other hand.

The present invention was developed in view of these circumstances, and its purpose is to eliminate the danger of handling by controlling the springing up of the presser rod, and to make it possible to bind documents with only one hand. The aim is to provide a paper clip that can be used to hold paper.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
In the figure, reference numeral 1 denotes a base body, and upstanding pieces 2 and 3 are formed at both ends thereof.

Further, an upstanding piece portion 4 is also formed on the back surface of the base body 1.

One end of the standing piece 2 has parallel line parts 5a', 5a'' made by bending one wire rod, which are bent downward in an arch shape at the center, and a document holder is attached to the center part of the wire rods 6a', 5a''. The base 6C of the pressing rod 6 to which the plate 5 is attached is inserted into and pivotally connected to the shaft tube 7 fixed to the upright piece 2 at one end, and the upright piece 2 and the base of the pressing rod 6 at one end are connected to each other. 6C, a spring member, for example, a torsion recoil spring 8 formed by fitting a coil part 8C to the base part 6C, is provided, and one end 8a of this torsion coil spring 8 is hung on one end of the base 1 by the upright piece part 2, and torsion coil spring 8
By hanging the other end 8b on the pressing rod 6, the pressing rod 6
is constantly biased in the direction away from the base 1.

The other end of the upright piece 3 is provided with a hook 10 formed by a cut-and-raised piece, and the tip 9 of the pressing rod 6 is removably engaged with the hook 10; Hole 11
A hooking member 11 having an opening (a) is provided with an operating piece (111) and is rotatably mounted l''.

In the figure, reference numeral 12 denotes a T-shaped locking portion formed on the document holding plate 5.
It is made to penetrate and engage with a vertically elongated retaining hole 13 bored in the.

The upper edge of this engagement hole 13 constitutes a stopper portion 14 of the present invention.

That is, the tip flange portion 12 a j2 b of the locking portion 12
By locking the locking member 12 on the back surface of the peripheral edge of the engagement hole 13 to prevent it from being removed unnecessarily, and by blocking the locking member 12 with a stopper portion 14 formed at a predetermined height position of the engagement hole 13. The separation position of the pressing rod 6 from the base body 1 is regulated.

The base body 1 is provided with mounting holes 15 and 15' for mounting the base body 1 on the file A.

Therefore, when attempting to bind documents using the paper clip configured as described above, first, the engagement hole 11a of the end engagement member 11 of the press rod 6 and the other end upright piece 3 of the base 1 are connected. Release the engagement with the hook part 10.

In this state, the pressing rod 6 (j) is always urged in the direction away from the base 1 by the spring force of the torsion coil spring 8, so that it is at a position seven springs away from the base 1, and the pressing rod Since an appropriate gap is formed between the document holding plate 5 of No. 6 and the base body 1, it is possible to use this gap to hold and hold the documents to be bound with one hand, for example.

After the documents have been inserted, by pressing the pressure rod 6 against the base 1, the documents are held and bound between the document holding plate 5 of the pressure rod 6 and the base 1, and the documents are bound by the pressure rod 6. The engaging hole 11a of the tip engaging member 11 is engaged with the engaging part 10 of the other end upright piece 3 of the base body 1, and the document binding operation is completed.

Next, when attempting to remove the bound document, the engaging state between the end engaging member 11 of the pressing rod 6 and the engaging portion 10 of the base body 1 is released.

In this case, by releasing the engaging state of the engaging part 10 of the base body 1, the pressing rod 6 will forcefully spring up with the engaging part 12 engaged with the engaging hole 13; Since the position at which the lever springs up is regulated by the locking portion 12 being pressed against the stopper portion 14, there is no danger that the tip of the pressing rod 6 will hit the face or the like.

In the above embodiment, the shape of the locking part 12 is T-shaped, and the stopper part 14 against which the locking part 12 is stopped is formed by the upper edge of the retaining hole 13 formed in the back upright piece part 4. However, this case is not limited to this case. For example, as shown in FIG. An engagement groove 13 in which the portion 12a' is engaged is formed by cutting and raising the rear upright piece 4, and this engagement groove 13
A stopper part against which the locking member 12' is stopped may be provided at a predetermined height position of the rear upright piece 4. Also, a protrusion protruding toward the front side may be provided at a predetermined height position of the rear upright piece 4, and this protrusion is used to press the stopper part. In the present invention, which may constitute a stopper against which the rod 6 is stopped, as explained above, the pressing rod is constantly urged in the direction away from the base body by the spring force of the spring. It is located at a position that has been pushed up from the base, and an appropriate gap is formed between the pressure rod and the base, so you can easily use this gap to, for example, hold a document to be bound with one hand. It can be held in place, and when the binding member at the tip of the press rod and the hook on the base are disengaged in an attempt to remove the bound document, the press rod will forcefully spring up. However, since the position at which the pressing rod 6 springs up is regulated by the stopper portion, accidents such as the tip of the pressing rod hitting the face or the like can be prevented.
