  A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, embodiment is not limited to the following forms, Other aspects can also be implemented if the subject of this invention can be solved.

FIG. 1 is a perspective view showing a clip 1 according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view.
This clip 1 is for bundling and binding sheet materials such as paper, and by bending a resilient metal plate into a U-shape, a back surface portion 10 for contacting the end surface of the sheet, First and second sandwiching portions 20 and 30 for sandwiching the sheet surface are formed.
The 1st clamping part 20 is a site | part for hold | maintaining one surface (for example, surface) of a sheet | seat, and is cut | disconnected in the U shape toward the back surface part 10 side from the front-end | tip part.

The U-shaped cut portion 21 is bent inward at the base portion, and is pressed against the second clamping portion 30 at the end portion 22.
In this case, the sheet is pressed and held with a strong force by urging the cut portion 21 so that the edge portion 23 of the end portion 22 of the cut portion 21 is pressed against the plate surface of the second clamping portion 30. I am doing so.

The 2nd clamping part 30 which faces the 1st clamping part 20 is a site | part for hold | maintaining the other sheet | seat surface (for example, back surface), and the notch part 21 of the 1st clamping part 20 is press-contacted. .
By inserting a bundle of sheets 2 between the two sandwiching portions 20 and 30 (see FIG. 3A), the sheet 2 is advanced along the inclined cut portion 21 toward the back surface portion 10. The cut portion 21 is elastically deformed by being pushed by the bundle of sheets, and the bundle of sheets 2 is inserted into the gap formed thereby to sandwich the sheet bundle (see FIG. 3B).

The open end portions of the first and second sandwiching portions 20 and 30 are slightly curved toward the outside, and the curved portions constitute guide portions 25 and 35 for guiding the bundle of sheets 2. Yes.
The back surface portion 10 of the clip is a portion for bringing the end portions of the sheets held by the first and second holding portions 20 and 30 into contact with each other.
An opening 11 is provided in the center in the horizontal direction of the back surface 10. The opening 11 is a space for accommodating the corner 2 'of the sheet 2 sandwiched by the first and second sandwiching sections 20 and 30 (see FIG. 4). The opening width is designed according to the thickness.

A method for manufacturing the clip 1 will be described with reference to FIG.
An opening 11 is provided at the center of the metal plate, and a U-shaped (21) notch 21 is provided from one end of the metal plate toward the opening 11 (see FIG. 5A).
And the both sides 12 and 12 of the opening part 11 are bend | folded, and a cross-sectionally U-shaped clip member is formed (refer FIG.5 (b)). As a result, a back surface portion 10 having an opening 11 and a pair of sandwiching portions 20 and 30 continuous from the back surface portion 10 are formed.

Then, the cut portion 21 provided in one of the sandwiching portions 20 is bent inward, and is brought into pressure contact with the other sandwiching portion 30.
Thereafter, the end portions of both sandwiching portions 20 and 30 are slightly bent to form guide portions 25 and 35 for facilitating sheet insertion (see FIG. 5C).
The usage state of the clip 1 manufactured in this way will be described.

First, as shown in FIG. 3, the bundle-like sheet 2 is inserted between the first and second sandwiching portions 20, 30, and advanced to the back along the inclined cut-out portion 21. The cut portion 21 is pushed and elastically deformed, and the bundle of sheets 2 is inserted between the edge portion 23 and the second sandwiching portion 30.
Then, the clip in a state where the sheet 2 is pressed and held by the first and second sandwiching portions 20 and 30 is moved to the corner portion of the sheet 2 (see FIG. 4A), and the back surface portion 10 of the clip 1 is moved. The corner portion 2 ′ of the sheet 2 is inserted into the opening 11 provided in (see FIG. 4B). As a result, it is possible to prevent the clip from falling off when the sheet is rolled up and falling off.

  In the clip according to the present embodiment, a cut portion 21 directed from one end portion of the metal plate toward the back surface portion 10 is bent inward and pressed against a second sandwiching portion 30 for holding the back surface of the sheet 2. Therefore, the sheet can be smoothly guided to the press contact portion at the end while being guided along the inclined cut portion 21. This makes it possible to attach the clip without using a special instrument.

Further, since the second clamping part 30 is pressed against the edge part 23 of the end part 22 of the cut part 21, a pressing force in a direction opposite to the direction in which the sheet 2 comes out is applied to the plate surface of the second clamping part 30. Can act on.
Accordingly, it is possible to prevent the pressed sheet 2 from moving in the direction opposite to the insertion direction and detaching the clip.

  Note that the cut portion of the present embodiment may have an apex 24 having an acute angle toward the back surface side 10 like a cut portion 21 ′ shown in FIG. 6. In this way, since the pressing force can be concentrated at one point, the sheet can be held with a strong force, and the sheet can be more effectively prevented from moving in the direction opposite to the insertion direction. it can.

Further, like the clip 1 ″ shown in FIG. 7, the end portion 22 ″ of the cut-out portion 21 ″ may be bent so as to contact the second sandwiching portion 30 in a planar shape. It becomes possible to hold the sheet with a uniform pressing force on a wide pressure contact surface, and when the clip is removed, it is possible to prevent the mark of the clip from being left on the sheet.
Further, as shown in FIG. 8, a U-shaped cut (first cut portion) having a hanging hole 15 is provided in the center of the metal plate, and the hanging portion 16 is bent by bending the cut outward. The sheet pressing and holding portion may be formed by the second cut portion 21 formed and directed toward the back surface portion 10 side.

Also, the second holding part is provided with the same notch as the first holding part, and the notch is bent inward so that the end is pressed against the end of the notch of the first holding part. May be.
If it does in this way, it can be set as a clip which can be used without distinguishing front and back. When the clip is attached, the sheet can be strongly held by the pressing force from both sides, and when the clip is removed, the elastic force of both the first and second clamping parts is used. The gap can be easily opened.

Next, a clip 200 according to a second embodiment of the present invention will be described with reference to FIG.
The clip 200 bends an elastic metal plate, thereby bringing the back surface portion 210 into contact with the end face of the sheet, the first holding portion 220 for holding the sheet surface, and the second holding portion 230. And formed.
The 1st clamping part 220 is a site | part for hold | maintaining one surface (for example, surface) of a sheet | seat, and is comprised by the plate member curved in the convex shape inside.

As shown in FIG. 10, the first sandwiching portion 220 forms a curved guide portion 222 from the leading end portion where the sheet is inserted toward the central convex portion 221. And it is press-contacted to the 2nd clamping part 230 in the area | region from the convex part 221 to a rear-end part.
The pressure contact region is bent outward from the rear end 221a, and a pull-out guide portion 223 is formed on the bent surface so that the sheet can be easily pulled out when the clip is removed.

A second clamping part 230 is formed so as to face the first clamping part 220.
The second sandwiching portion 230 is a portion for holding the other sheet surface (for example, the back surface), and is curved from the tip portion toward the central convex portion 231, similarly to the first sandwiching portion 220. The guide portion 232 is formed and is in pressure contact with the first clamping portion 230 in a region from the convex portion 231 to the rear end portion. Then, similarly to the first holding part 220, the pull-out guide part 233 is formed by a bent surface toward the rear end part, which is bent at the rear end 231a of the pressure contact area.

These sandwiching portions 220 and 230 are connected to the back surface portion 210 via T-shaped connecting portions 224 and 234.
The back surface portion 210 is a portion with which the end portion of the sheet comes into contact, and an opening 211 is provided in the central portion in the horizontal direction. As shown in FIG. 11, the opening 211 is a space for accommodating the corner portion 2 ′ of the sheet 2 sandwiched by the first and second sandwiching portions 220 and 230, and the clip 1 is sandwiched by the opening 211. The opening width is designed according to the thickness of the sheet bundle that can be formed.

The center portion 212 in the longitudinal direction of the back surface portion 210 is slightly recessed inward, and the urging force when the tips of the sandwiching portions 220 and 230 are expanded is smoothly acted through the connecting portions 224 and 234. (See FIG. 10 (d)).
Further, when the sheet 2 is inserted from the leading ends of the sandwiching portions 220 and 230, the convex portions 221 and 231 are pushed toward the back surface portion 210 by the thickness of the sheet 2. It is elastically deformed in the direction and is designed in such a shape that the sheet 2 is firmly pressed and held at the bent portions of the rear ends 221a and 231a of the convex portions 221 and 231 (see FIG. 12).

A method of manufacturing the clip 1 will be described with reference to FIG.
An opening 211 is provided in the center of the metal plate, an L-shaped cut (K, L) is provided toward the opening 211, and a T-shaped portion formed thereby is formed by a back surface portion 210 and a sandwiching portion 220, 230 connecting portions 224 and 234.
Then, the sandwiching portions 220 and 230 are curved inward to form convex portions 221, 231 and the connecting portions 224, 234 are curved so that the outer side is convex (see FIG. 13B). The center portion 212 in the longitudinal direction of the back surface portion 210 is slightly curved inward.

After that, bend the both sides of the opening 211 inward at fold lines 213 and 213 perpendicular to the connecting parts 224 and 234 (see FIG. 13C), and the respective holding parts 220 and 230 are The curved convex portions 221 and 231 are pressed against each other.
As a result, a clip having a back surface portion 210 having an opening 211 and a pair of upper and lower clamping portions 220 and 230 continuous from the back surface portion 210 is formed.

  Thereafter, the rear ends 221a and 231a of the pressure contact regions in the respective sandwiching portions 220 and 230 are bent outward, and the extraction guide portions 223 and 233 are formed on the bent surfaces. The regions from the front ends of the sandwiching portions 220 and 230 to the convex portions 221 and 231 are smoothly curved, and guide portions 222 and 232 for guiding the sheet into the clip are formed on the curved surfaces.

The usage state of the clip 200 manufactured in this way will be described.
First, as shown in FIG. 12A, the bundle-like sheet 2 is inserted between the first and second sandwiching portions 220 and 230 and is advanced along the guide portions 222 and 232.
Then, the curved convex portions 221 and 231 are elastically deformed so as to slide toward the back surface portion 210 depending on the thickness of the sheet bundle (see FIG. 12B). Accordingly, the rear ends 221a and 231a of the convex portions 221 and 231 are further pressed toward the inside, and the sheet 2 is sandwiched.

Then, the clip 200 in a state where the sheet 2 is held by the first and second sandwiching portions 220 and 230 is moved to the corner portion of the sheet 2 (see FIG. 11), and the opening portion 211 of the back surface portion 210 is moved to the opening portion 211. Insert the corner 2 ′ of the sheet 2 (see FIG. 12C).
In this way, the corner 2 ′ of the sheet 2 is held in the opening 211, and further, the sheet 2 is firmly pressed in the curved sandwiching portions 220 and 230, so that when the sheet is rolled up, The clip can be prevented from falling off.

In particular, since the sandwiching portions 220 and 230 for pressing and holding the sheet 2 are configured by curved surfaces having convex portions 221 and 231 inwardly, the sheet 2 inserted from the front end portion is curved guide surfaces 222 and 232. While being guided to the rear surface portion 210, the center convex portions 221 and 231 can be smoothly inserted into the back surface portion 210 and can be mounted without using an instrument.
Further, when the sheet 2 is inserted toward the back surface portion 210, the curved convex portions 221 and 231 are elastically deformed so as to be pushed toward the back surface portion 210, so that the sheet is formed at the bent portions of the rear ends 221a and 231a. Can be held firmly.

In the clip according to the present embodiment, the bent portions of the convex rear ends 221a and 231a may be curved or may not be provided. The curved shape can prevent the sheet from being damaged when the clip is removed.
Further, like the clip 200 ′ shown in FIG. 14, only one clamping part 220 may be curved, and the other clamping part 230 ′ may be a flat surface. In the state where the sheet is sandwiched between the convex portion 221 and the flat surface portion 231 ′ that are curved inwardly, the corner portion of the sheet can be held in the opening portion 211 of the back surface portion 210. At this time, it is possible to prevent the clip 200 'from coming off.

  The present invention can be applied not only to office use but also to clips used in all industrial fields.
