Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for elastically sandwiching bundled sheets and temporarily fixing them without damage.

[0002]

2. Description of the Related Art This type of clip has been used for a long time, and two clip pieces are connected to each other by a pivot so that they can be opened and closed, and a vine spring is urged to keep the closed state. It has been widely used, and the wire rod is already in widespread use.The wire rod is put into an almost oval shape with a double winding, and the elasticity of the wire rod is used between the overlapping portions of the wire rods. It is widely used in recent years.The quenched spring plate material is bent into a U shape, and the clip pieces face each other through the U-shaped bent part. There is one in which each clip piece strongly presses against each other due to the return habit of the spring given to the U-shaped bent portion so that the paper sheets are strongly sandwiched.

[0003]

However, the above-mentioned conventional type in which two clip pieces are connected so as to be opened and closed by a pivot has a complicated structure and is expensive,
Since the bulkiness is high regardless of whether it is used or not, there is a problem that documents and the like cannot be put together in a low volume.

Further, although the wire rod is in a state of being double wound slightly, it is low in volume, but since the wire rod is only wound, it is inconvenient because various kinds of information such as the manufacturer name and advertisement cannot be displayed. Also,
When documents temporarily fixed with this type of clip are piled up, the clips are often caught or entangled with each other, and the clips are often used alone or in a state where papers are sandwiched between them, which is a support.

Further, a spring plate material bent in a U-shape so that two clip pieces are strongly pressed against each other has the advantages that it is relatively bulky and difficult to be caught, but the pinching force is strong. Past, connect the tip of the handle to the tip of each clip piece so that it can be undulated in a rotating manner, and open it using the lever action when the handle is tilted to the rear of the U-shaped continuous part, It accepts and removes paper, and its structure is complicated and expensive. Also, if the handle is left as it is, it will be overhanging and difficult to handle, so
When not in use, there is the inconvenience of having to flip it over to the side of the paper that holds the handle in place.

An object of the present invention is to solve the above-mentioned problems, and various kinds of display can be made as necessary, and the display is not bulky, is not caught or entangled, and is easy and labor-free. The object is to provide a clip of simple and inexpensive construction that can be used.

[0007]

In order to achieve the above-mentioned object, the present invention folds two clip pieces, which are integrally continuous with each other, into two at the continuous portion, and one clip piece is
Hold the posture in which this one clip piece is pressed against the other clip piece in a state of being convex on the front side, and it is reversed to the state of being convex on the back side and the one clip piece is bent back to separate from the other clip piece. It is characterized in that a reversing spring portion is formed.

It is preferable that the reversing spring portion has a circular shape extending up to the vicinity of the peripheral edge of the clip piece, and the width of the folded portion is preferably smaller than the width of the clip piece, and is more than the thickness of the sheets to be sandwiched. It is preferable to form a rising portion that defines the interval between the continuous portions of each clip piece.

One clip piece having at least the reversing spring portion of the clip piece is pressed, and the side where the return occurs is the inner surface.

[0010]

According to the above-mentioned structure of the present invention, the reversing spring portion is provided on one of the two clip pieces which are folded in two by the continuous portion which is integral with each other. By pressing the surface so that it is convex on the front side or convex on the back side, one clip piece comes into pressure contact with the other clip piece so that paper can be elastically sandwiched between the two clip pieces. Or, one of the clip pieces can be warped to the surface side and separated from the other clip piece by using the continuous portion as a fulcrum to receive the papers, and can also be in a state of being pulled out. By simply pressing the center part of the reversing spring part that is convex on the front side of the other clip side, the reversing spring part can be reversed to a convex state on the back side, and this warped state One hand In both sides of the-up piece just to press the other of the clip on one side, a reversing spring portion can be inverted to the state protruding surface side. Further, the two clip pieces are flat and closely follow the paper to be sandwiched, and there is no catching or entanglement with other paper pieces, and the wide surface allows for various displays such as manufacturer names and advertisements.

When the reversing spring portion has a circular shape extending to the vicinity of the peripheral edge of the clip piece, the reversing is accurate, and one piece of the clip piece is sufficiently pressed against the other piece piece due to the reversal, and It is easy to take a large deformation stroke between the warped state and the warped state toward the surface side away from the clip piece.

When the width of the folded-back portion is smaller than the width of the clip piece, the one clip piece is pressed against the other clip piece and the warped state of the clip piece toward the surface side away from the other clip piece. The deformation rigidity between them can be weakened so that this deformation can be performed easily and reliably.

If the folding portion forms a rising portion that defines the interval between the continuous portions of the clip pieces, which is larger than a predetermined bulk of the sandwiched paper sheets, the one clip piece is deformed by reversing the reversing spring portion. Regardless of the stroke, it is possible to obtain a sandwiching margin of a predetermined bulk or more, and it is possible to easily sandwich a large amount of paper sheets.

If one clip piece having at least the reversing spring portion of the clip piece is pressed and the side where the return occurs is the inner surface, the paper is elastically held between both clip pieces. When it is sandwiched in the paper, the return bar bites into the surface of the paper, so that the clip piece can be caught on the paper well.

In addition, the one clip piece 1 is held in a position in which the one clip piece 1 is pressed against the other clip piece 2 in a convex state on the front surface side, and the one clip piece is inverted to the convex state on the back surface. An inversion spring portion 4 is formed to bend back one piece away from the other clip piece 2.

The reversing spring portion 4 is formed by the clip piece 1.
If is formed of a metal plate having an appropriate elasticity such as an iron plate, a steel plate, a stainless steel plate, etc., it can be obtained without using a spring plate that has been particularly quenched. However, a spring plate can also be used.

The clip pieces 1 and 2 are integrally formed with the continuous portion 3 from the same material as shown in the respective drawings, and are shown in FIG. 2 of the first embodiment and FIG. 9 of the second embodiment. A metal plate punched into various desired shapes as shown is folded in two at the continuous portion 3 as shown in FIGS. 1, 7, 10, and 11 of each embodiment. However, clip pieces 1 and 2
May be formed by separate members, and the continuous portions 3 provided on either or both of them may be connected by the continuous portion 3 which is a separate member. These are suitable when only the clip piece 1 having the reversing spring portion 4 is formed of a spring plate. Figure 1
In a fifth embodiment shown in FIG. 2, a clip piece 2 made of a non-metallic material such as resin or ceramic material, and a clip piece 1 made of a metal plate and having the inversion spring portion 4 integrally formed with the clip piece 1. Are integrated by being inserted into the clip piece 2 side. Such connection can be easily and surely achieved by the insert molding method of the clip piece 2. However, in order to connect the clip pieces formed separately, it is possible to use various known methods such as welding, bonding, pinning, and screwing according to the material.

In each of the first to fifth embodiments, the reversing spring portion 4 provided on one clip piece 1 is projected toward the surface side of the one clip piece 1 (see FIGS. 1, 3, and 5). , FIG. 7, FIG. 10 to FIG. 12) or the back side convex (FIG. 4 and FIG. 6), the one clip piece 1 is pressed.
Is pressed against the other clip piece 2 (see FIGS. 1, 7, and 10).
(FIG. 12) The state in which the paper 5 is elastically sandwiched between the two clip pieces 1 and 2 (FIG. 3, FIG. 5, FIG. 8),
One clip piece 1 is bent back toward the front surface side as representatively shown in FIGS. 4 and 6 of the first embodiment, separated from the other clip piece 2 with the continuous portion 3 as a fulcrum, and receives the papers 5, In addition, it can be put in a state where it can be extracted.

Therefore, the papers 5 can be elastically sandwiched and held by a simple and inexpensive structure, and the papers can be pulled out by releasing this holding. Also, since it is flat and not bulky, and since it is along the surface of the paper sheet 5, it does not get caught or entangled with others, so
It is easy to handle even when paper 5 is sandwiched. Moreover,
There is also an advantage that various types of displays such as manufacturer names and advertisements can be displayed by utilizing the wide surfaces of the clip pieces 1 and 2.

As shown by phantom lines in FIGS. 1B and 1C of the first embodiment, a sheet 6 on which an advertisement is printed is attached to the surface of one clip piece 1, and the other is attached to the other side. A magnet rubber 7 is attached to the surface of the clip 2. The magnet rubber 7 allows the paper clips 5 of the present embodiment to be attracted to the surface of various magnetic boards possessed by an existing object by magnetic force, and the papers 5 to be sandwiched and held can be suspended and supported.

In the pressing operation, the central portion of the reversing spring portion 4 which is convex on the surface side of one clip piece 1 is
The inversion spring portion 4 is represented by FIGS. 4 and 6 of the first embodiment only by pressing the other clip piece 2 side as indicated by the arrow F1 representatively shown in FIG. 3 of the first embodiment. As shown in the drawing, the clip piece 1 can be reversed to a convex shape on the back surface side, and is in the warped state. One clip piece 1 shown in FIGS. 4 and 6.
By simply pressing both left and right sides of the clip toward the other clip piece 2 side as indicated by arrow F2 shown in FIG. 4, the reversing spring portion 4 can be reversed to a convex state on the surface side as shown in FIG. Such an operation can be performed extremely easily by pressing it with a finger from above on the table surface, for example, and it can also be performed very easily by holding and pressing between the thumb of one hand and the index finger and the ring finger. Therefore, the work of sandwiching or pulling out the papers 5 is easy and convenient for use.

In each of the first to fifth embodiments, the reversing spring portion 4 has a circular shape extending to the vicinity of the peripheral edge of the clip piece 1. As a result, the reversal of the reversing spring portion 4 is accurate, and due to this reversal, the one clip piece 1 is in a sufficient pressure contact state with the other clip piece 2 and the warped state toward the surface side away from the other clip piece 2. It is easy to take a large stroke between and. Therefore, when the paper 5 is pulled out, when the paper 5 is pulled out, the clip pieces 1 and 2 are widely opened so that the pulling out work can be easily performed without any resistance, while sufficiently obtaining the elastic pinching force when the paper 5 is pinched. be able to.

However, the reversing spring portion 4 is not limited to the circular shape, but may be an elliptical shape or other various shapes.

The width B of the folded portion formed by the continuous portion 3 is smaller than the width BO of the clip pieces 1 and 2. As a result, the deformation rigidity between the one clip piece 1 pressed against the other clip piece 2 and the warped state toward the surface side away from the other clip piece 2 is weakened, and this deformation is easy and It can be ensured.

In the first embodiment shown in FIGS. 1 to 5, in order to make the width B of the folded portion formed by the continuous portion 3 smaller than the width BO of the clip pieces 1 and 2, the clip pieces 1 and 2 have the same width. The plane shape is almost fan-shaped. However, the shape is not limited to this, and any shape can be adopted.

In the first embodiment, the clip pieces 1,
2 is stamped and formed, as shown in FIG.
As shown in (a) and (b), the side where the return 8 occurs is the inner surface. As a result, when the paper 5 is elastically sandwiched between the clip pieces 1 and 2, the return 8 bites into the surface of the paper 5 as shown in FIG. You can improve the chances of being caught in a class.

Since such a return 8 can be naturally formed as long as the clip pieces 1 and 2 are pressed with a metal plate, no special work is required, and both the clips 1 and 2 are so formed. Is preferred. However, it is also possible to form a catching portion such as a saw-tooth-like unevenness by a special process. By the way, as in the fifth embodiment shown in FIG. 12, since one clip piece 1 having the reversing spring portion 4 is always formed of a metal plate, at least this one clip piece 1 is returned by pressing. By holding it so that it faces the inner surface, the above-mentioned catching characteristic can be obtained.

In each of the second to fifth embodiments shown in FIG. 7 and subsequent figures, the folded portion formed by the continuous portion 3 has a gap between the clip portions 1 and 2 on the continuous portion side that is equal to or larger than a predetermined bulk T of the sheets 5 to be sandwiched. A rising portion 9 that defines S is formed. As a result, regardless of the deformation stroke due to the reversal of the reversing spring portion 4 of the one clip piece 1 or 2, it is possible to obtain a pinching margin of a predetermined bulk T or more, and to easily pinch a large amount of sheets 5 or the like. be able to.

In each of the second to fifth embodiments, in order to weaken the bending rigidity between the rising portion 9 and the rising portion 9, the width B of the continuous portion 3 forming the rising portion 9 is set to be smaller than that in the first embodiment. It's even smaller. As a result, the clip piece 1 is reasonably pressed against the clip piece 2 by reversing the reversing spring portion 4 and warped to the surface side away from the clip piece 2, and in the pressure contact state with the clip piece 2. For example, as shown in FIG. 8, the sheets 5 to be sandwiched are made to be easily aligned. However, the shape of each rising portion 9 can be changed in various ways, and the shape shown by the phantom line in FIGS. 7, 10 and 11 is more suitable for weakening the bending rigidity.

In each of the second to fifth embodiments, the clip pieces 1 and 2 are made to have a heart-shaped planar shape, and the surfaces of the clip pieces 1 and 2 are printed or coated so that the edges of the clip pieces 1 and 2 are printed. The whole heart shape is represented without regard. A heart-shaped sheet may be attached instead of the printing or coating.
