[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for bundling sheets such as paper and film, which is made of a bent metal wire.

[0002]

2. Description of the Related Art As a clip of the kind described above, a typical one is a so-called zem clip which is commercially available, but other types of clips are also known.
When these are roughly divided in terms of shape, they are symmetrical and asymmetrical.

[0003]

In the case of left-right asymmetrical ones including rotationally symmetrical ones, when a clip is inserted into a sheet, a part of the clip tends to float from the sheet. A symmetrical one is better in this respect,
One of the holding portions located on the front and back surfaces of the sheet is divided into left and right parts, which is inferior in ease of sheet insertion.

[0004]

SUMMARY OF THE INVENTION The present invention is a flat clip made of a bent metal wire, comprising a front clamping portion and a back clamping portion, and the back clamping portion has a left widening portion and a right widening portion. The left and right widened portions are connected to the front holding portion, respectively, and have contact portions that come into contact with each other, and are opposite to the ends of the contact portions connected to the front holding portion.
Widen the widened part from the end on the side to the side of the clamping part
The back holding portion is formed so that both sides of the back holding portion and the contact portion are flush with each other, and the front holding portion and the back holding portion are relatively protruded from the other side. Become
The gist is a symmetrical clip.

[0005]

FIG. 1 shows an example. The clip A is formed by appropriately bending a metal wire such as stainless steel or phosphor bronze. It has a symmetrical shape. The wire may have an appropriate cross section, such as a circle, or may have a synthetic resin tube or a film formed by painting or the like. This clip A
In the figure, reference numeral 1 indicates a front clamping portion, and reference numeral 2 indicates a back clamping portion. However, the front and back sides are relative, and which holding portion is located on the front side of the sheet depends on the use.

The front holding portion 1 is formed in a square frame shape, and the back holding portion 2 includes a left widening portion 3 and a right widening portion 4 which widen to the left and right, respectively. The widened parts 3 and 4 are the front holding parts 1
The center of the upper side 1a is connected to the front holding portion 1, and has contact portions 3a and 4a that contact each other over a predetermined length. The contact portions 3a and 4a may not be provided if the sheet thickness that can be clamped is not required to be relatively thin, but at this time, the contact is not performed.
It is preferable that the contact portions 3a and 4a are formed with a certain length from the upper side 1a to the lower side of the holding portion 1 and that the contact portions 3a and 4a are close to each other with some gaps formed. .

The clip A has a flat shape. According to FIG. 1, this flat shape is such that the front holding portion 1 and the back holding portion 2 appear to be in one plane. However, as schematically shown in FIG. 2, the upper side 1a of the front holding portion 1 protrudes from the plane formed by the other three sides of the front holding portion 1, that is, the left side 1b, the right side 1c, and the lower side 1d, and the back side is held. The plane formed by the part 2 is different. This projection facilitates sheet insertion. Also, the contact portions 3a, 4a of a predetermined length of the wide portions 3 and 4 of the back clamping portion 2 and the proximity portion having a certain length instead of the contact portions 3a and 4a are inserted into the clip A with a fingertip or the like when inserting the sheet. It becomes a portion for applying a deformation force, and makes sheet insertion easier. Incidentally, the optimum protrusion height is the thickness of the wire rod. In addition, such protrusions as portions other than the upper side 1a of the front holding portion 1 such as the contact portions 3a and 4a, a part of the left side 1b including the lower side 1d and a part of the right side 1c including the lower side 1d. Although it is not impossible to form a flat portion, three sides other than the upper side 1a of the front holding portion 1 and the back holding portion 2 are portions located on each surface of the sheet. Is more preferred.

When viewed from the front, the width of the widening portions 3 and 4 is such that the rear holding portion 2 is inscribed in the front holding portion 1. That is, the width is increased to the left side 1b and the right side 1c of the front holding portion 1. It should be noted that the front holding portion does not necessarily have to be square as shown in an example later, but may be widened to the side of the appropriately shaped front holding portion.

The widening amount of the widening portions 3 and 4 can be further increased. Hereinafter, basically, the same reference numerals are used for the same parts. For example, in the case shown in FIG. 3, the back clamping portion 2 has the same width as the front clamping portion 1. The width may be further increased. By doing so, the contact portions 3a,
Although it depends on the length of 4a, the upper side 1a of the front holding portion 1 can be projected substantially as shown in FIG. Of course, a clamping force can be applied even when the sheet is not inserted between the clamping portions 1 and 2.

Further, the relative protrusion of the front holding portion 1 and the back holding portion 2 enables the use of a holder B as shown in FIG. 5, for example. The holder B urges the clip A housed in the folded state with the elastic body 5, pushes the clip A by one by the pressing body 6, advances the clip A, and expands the clip A by the expanding body 7 positioned forward. The expanding body 7 has a pressing portion 7a of the front holding portion 1 and a pressing portion 7b of the back holding portion 2, and the front holding portion 1 of the clip A is located below the pressing portion 7a in the drawing. Side, and the back clamping portion 2 passes above the push-up portion 7b. If the sheet is inserted between the holding portion 7a and the push-up portion 7b, it can be inserted without directly expanding the clip A. Here, the symmetrical shape of the clip A also contributes to the compactness of the tatami mat. In addition, if the relationship between the pressing portion 7a and the push-up portion 7b of the expanding body 7 is reversed, the clip A is housed upside down. In FIG. 5, the clip A is shown in FIG. 3, but may be the one shown in FIG. 1 or, for example, the one shown in FIG. FIG. 6 shows a case where a ring-shaped wire is used.

[0011]

According to the present invention, a flat clip made of a bent metal wire has a front clamping portion and a back clamping portion, and the back clamping portion has a left widening portion and a right widening portion. Each of the left and right widened portions is connected to the front holding portion and has a contact portion with which each comes into contact.
Starting from the end opposite to the end connected to the front
The widened portion is widened to the side of the front holding portion, and the back holding portion is formed so that both sides of the back holding portion and the contact portion are flush with each other. this and the back clamping portion, it protrudes from the relatively other, and, since the clip symmetric shape, causing the sheet much deformed
Not only stable sheet inserted state can be obtained without the,
Sheets can be easily inserted. In particular, since the holder can be used, the ease of inserting the sheet is greatly improved. Moreover, it can be folded compactly, which is advantageous for storage and storage.
