Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a clip for clamping and fixing paper or documents.

(Prior Art) Clips are widely used in companies, various offices, schools, and households. However, in order to hold paper in conventional clips, a pair of clipping pieces are usually separated against elasticity, and the paper is inserted between them. In addition, each of the clipping pieces makes line contact with the paper, or even if surface contact occurs, the paper is likely to come off from between the clipping pieces because the surface contact is on a smooth surface.

(Purpose of the invention) The present invention was made in order to solve the above-mentioned problems with conventional paper clips, and it is possible to easily clip and fix paper or documents without requiring special force. To provide a clip that can hold paper or documents easily and prevents the paper or document that has been clipped from falling off easily.

(Structure of the invention) The clip according to the invention is provided with a pair of presser pieces extending outward from a curved part of an annular spring piece having a pair of parallel pinch pieces at both free ends, and one of the pinch pieces. A band-like projection is provided on the flat inner surface, and an eccentric shaft is supported on the other side of the sandwiching piece, and the front half of this eccentric shaft is formed into a columnar shape, and the rear half is formed into a continuous approximately triangular prism shape. , characterized in that a band-shaped protrusion is formed on the flat portion facing the band-shaped protrusion.

The clip according to the present invention will be explained below based on the drawings showing the embodiments. FIG. 1 is an exploded perspective view showing one embodiment of the clip according to the present invention, and FIG. 2 is a perspective view as seen obliquely from the rear.

As shown, the clip according to the present invention includes a steel annular spring piece 1 having two free ends biased in the closing direction, and a pair of presser pieces 7 extending outwardly from the curved portion and substantially parallel to each other. The two free ends form a pair of parallel sandwich pieces. In the illustrated embodiment, the spring piece itself is cut open at its central part 6 to provide a pair of retaining pieces. One of the clips is flat and has a strip projection 8 projecting on its inner surface in the axial direction of the annular spring piece, and preferably the edge 9 of the clip is further curved outwards. An eccentric shaft 2 is pivotally supported on the other sandwich piece.

As shown in the figure, the eccentric shaft 2 has a front half formed in a columnar shape, and a rear half formed in a substantially triangular columnar shape continuous with this semicircular columnar section. Band-shaped protrusions 10 are also formed on the flat portions.

A pair of bearings 4 having a shaft hole 5 are provided on the other sandwich piece, and the eccentric shaft 2 is supported between the bearings by a shaft body 3, and in a normal state, the belt-like projection 10 is It is made to face the band-shaped protrusion 8 of the first clipping piece. As shown, the eccentric shaft has a shaft hole 21, into which the shaft 3 is inserted,
This shaft body may be supported by the bearing 4, but it may also be formed integrally with an eccentric shaft provided with the shaft body, for example, using synthetic resin. Furthermore, if necessary,
The band-shaped protrusions 8 and 10 may also be formed integrally with the clip or eccentric shaft, respectively, or, for example, a rubber piece or the like provided with the band-shaped projection may be joined to the clip or the eccentric shaft.

Next, the use of the clip according to the present invention will be described.

To secure a paper or document between the clips, insert the paper or document between the clips and push it inside, and the eccentric shaft will rotate easily and stop the paper or document from being inserted. At this point they are fixed between the scissors by the biasing force of the annular spring. in this way,
Once the paper or document is fixed between the clips, even if you try to pull the paper or document out of the clip, the eccentric shaft cannot rotate, and the paper or document cannot be pulled out due to the action of the spring between the strips. Since it is pinched, it cannot be easily pulled out, and therefore, under normal conditions, paper or documents do not easily separate from the pinch piece. However, if the presser pieces are held between the fingers and pressed against each other, the pinch pieces are forcibly separated, so that paper or documents can be easily taken out from between the pinch pieces.

(Effects of the invention) As described above, according to the clip of the invention, it is possible to insert paper or documents between the clips and fix them without requiring any special force. Paper or documents once fixed in this way are not easily detached because the eccentric shaft is prevented from rotating. However, by pressing the presser pieces together and forcibly separating the pinch pieces, paper and documents can be
It can be easily taken out from between the clips.
