Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a clip for holding a document or the like.

[0002]

2. Description of the Related Art A wide variety of clips for holding documents or newspapers are known, but few have simple structures. Among them, there is, for example, one disclosed in Japanese Utility Model Laid-Open No. 7-769. As shown in FIGS. 2 and 3 of the publication, a U-shaped main body is fitted with a U-shaped pressing member, and as shown in FIG. It is described that if it is inserted between, it can be securely clamped.

[0003]

However, in the above-described apparatus, the pressing member is bent from the beginning in a L-shape. Even if a document or the like is inserted, the pressing force against the document is weak, and the pressing of the document or the like is weak. When the sheet is pulled out, the angle formed between the press-contact member and the document or the like is small, so that the contact friction is small, and there is a drawback that the document or the like easily comes off.

An object of the present invention is to provide a clip which can solve the above-mentioned drawbacks and has a simple structure and can securely hold a document or the like.

[0005]

In order to solve the above-mentioned problems, a clip according to the present invention has a first support piece and a second support piece which are opposed to each other. And a free end side of the second support piece is extended through a hinge groove to form a holding piece, and the holding piece is folded back from the hinge groove and the tip thereof is connected to the first holding piece.
A document or the like is inserted between the first support piece and the pressing piece to be pinched.

It is preferable that the space between the first support piece and the second support piece is formed such that the connection side is wide and the open side is narrow.

[0007] Further, a holding piece is formed to protrude outside each of the first support piece and the second support piece, and the holding piece is pinched to expand the space between the first support piece and the pressing piece. It is preferable to make it possible.

Further, in the clip according to the present invention, one side ends of the first support piece and the second support piece facing each other are connected by a connection piece so as to have a substantially U-shaped cross section.
The free end sides of the first support piece and the second support piece are extended through hinge grooves to form first and second holding pieces, respectively, and these holding pieces are connected to the hinge grooves. , And a document or the like may be inserted between the first pressing piece and the second pressing piece to be nipped.

Further, the clip may be made of a metal material.

[0010]

FIG. 1 is a perspective view of a clip according to the present invention, and FIG. 2 is a sectional view thereof. This clip is made of synthetic resin and has a first support piece 1 and a second support piece 2 facing each other.
One end of the support piece 2 is connected by a connecting piece 3 so as to have a substantially U-shaped cross section, and the free end side of the second support piece 2 is formed by bending a holding piece 5 inward through a hinge groove 4. And
The tip is brought into contact with the inner surface of the first support piece 1. The angle between the second support piece 2 and the connection piece 3 may be a right angle, but the angle between the first support piece 1 and the connection piece 3 is an acute angle.

The holding piece 5 is formed on the extension of the second support piece 2 in advance as shown by a dotted line in FIG. 2 and is integrally formed as a whole, and then, as shown by a solid line, a hinge groove. It may be formed by folding inward from 4.

A curved guide portion 6 is formed on the open end side of the first support piece 1. The holding piece 5 is also curved so that the angle between the inner surface of the first support piece 1 and the holding piece 5 on the open side is increased. Further, it is preferable that the tip 5a of the holding piece 5 is formed to have an acute angle.

Since the holding piece 5 is bent from the hinge groove 4, both sides of the valley of the hinge groove 4 are pressed against each other. For this reason, as shown in FIG. 3, since the elasticity of the pressing piece 5 to return to the original state acts on the pressing piece 5, its tip strongly presses the inner surface of the first support piece 1.

When using the clip, a document 7 or the like is placed between the first support piece 1 and the holding piece 5 as shown in FIG.
Just plug in. The documents 7 are guided by the guide unit 6 and are easily inserted. Since the pressing piece 5 is urged toward the first support piece 1, the inserted document 7 is strongly clamped between the first supporting piece 1 and the pressing piece 5. When the document 7 is to be pulled out of the clip, the tip 5a of the holding piece 5 is also moved to the open side of the clip as shown in FIG. Since the distance between the support piece 1 and the support piece 1 is reduced, the pressure on the document 7 or the like is increased, and the resistance against the drawer is increased. If the inclination of the holding piece 5 is small, the angle between the holding piece 5 and the document 7 becomes small, and the frictional resistance between them is also small. However, since the holding piece 5 is curved, the angle α between the holding piece 5 and the document 7 is large, and the friction between the two is large, the slip cannot be easily performed. For this reason, the resistance to pulling out is extremely large and cannot be pulled out unless a considerable force is applied, so that the holding force of the document is large.

As shown in FIG. 6, a holding piece 8 may be formed to protrude outside each of the first support piece 1 and the second support piece 2. In this case, it is possible to expand the space between the first support piece 1 and the holding piece 5 by grasping the holding pieces 8, so that the work of inserting or pulling out the documents 7 can be easily performed. .

As described above, the bent portion of the pressing piece 5 of the clip has elasticity due to the interference of the both sides of the valley of the hinge groove 4 when bent. Due to this elasticity, a force acts on the holding piece 5 in a direction opposite to the bending, so that the tip 5 a of the holding piece 5 strongly presses the inner surface of the first support piece 1. Therefore, the holding force of the documents 7 is strong.

Next, when the held document or the like 7 is pulled out from the clip, the presser piece 5 inclined in response to this is going to rise. Since the holding piece 5 is curved, the angle α between the holding piece 5 and the surface of the document 7 is larger than when the holding piece 5 does not bend. If the angle is further increased by raising the piece 5, the friction increases synergistically. Therefore, the pull-out resistance is extremely large, and the pull-out cannot be performed unless a considerable force is applied.

Further, it is preferable that the angle α of the contact portion between the pressing piece 5 and the document or the like is as acute as possible. However, in the conventional structure, in order to increase the angle α, the first support piece 1 and the The distance between the two support pieces 2 must be increased. However, by forming the holding piece 5 in a curved shape, the angle of the contact portion between the holding piece 5 and a document or the like can be increased without increasing the distance between the first supporting piece 1 and the second supporting piece 2. And the clip can be made compact. Therefore, even when the holding piece 8 is formed as shown in FIG. 6, the entire clip can be prevented from becoming too large.

A plurality of parallel grooves are formed on the upper surface side (the side that comes in contact with the document 7) of the holding piece 5 in order to increase the contact friction with the document 7 or the like, or rubber or soft synthetic resin or the like is used. Such a material having a large frictional force may be attached.

Also, as shown in FIG.
The free end sides of the first support piece 1 and the second support piece 2 are extended via the hinge groove 4 to form a first holding piece 5A and a second holding piece 5B, respectively. 5A and 5B may be folded back from the hinge grooves 4 so that a document or the like 7 is inserted between the first holding piece 1 and the second holding piece 2 and held therebetween.

Further, the clip may be made of a metal spring plate. Also in this case, as shown in FIG. 8, one side ends of the first support piece 1 and the second support piece 2 are connected by a metal connection piece 3 so as to have a substantially U-shaped cross section. The holding piece 5 is formed by extending the free end side of the support piece 2,
The pressing piece 5 may be formed so as to be folded back so that the tip thereof abuts on the inner surface of the first support piece 1.

By making the clip metal, the first
The holding force of the support piece 1 and the holding piece 5 is larger than that of the synthetic resin, so that documents and the like can be held more strongly.

Also in this case, two holding pieces may be formed as shown in FIG.
