  The problem to be solved by the present invention is to provide a pinching tool that can obtain a desired pinching width and can be simplified in appearance as compared with the prior art.

In order to solve the above-described problem, the pinching tool of the present invention includes a pair of pinching members having a pinching portion at one end and a pinching portion at the other end, and the pair of pinching members between the pinching portion and the pinching portion. Thus, the shaft portion that is pivotally connected, the biasing means that is provided between the pair of sandwiching members and biases toward the side where the sandwiching portions come into contact with each other, and the sandwiching portion of the sandwiching member is covered. And a cover made of a flexible synthetic resin or rubber, mounted or covered as described above,
Each of the pair of sandwiching members is made of a metal plate, and a part of the sandwiching portion located in the cover is punched into the sandwiching portion in the shape of a tongue piece whose tip is directed to the shaft portion side. The piece is bent in a direction in which the tip is directed toward the opposing sandwiching portion, and is configured as a pressing piece that prevents the cover from being removed and presses the cover toward the opposing sandwiching portion. .
According to this sandwiching tool, the object (for example, laundry) can be sandwiched between the sandwiching parts by the sandwiching force based on the biasing means by opening and closing the sandwiching part by grasping the knobs of the pair of sandwiching members. it can. A cover made of a synthetic resin or rubber having flexibility is attached or covered to the sandwiching portion so as to cover the sandwiching portion, so that this cover serves as an anti-slip against the object, and good sandwiching is achieved. A state is obtained.
And since this pair of clamping members are each comprised with the metal plate, compared with the thing of the said patent document 1, it is easy to obtain desired intensity | strength even if the thickness around an axis | shaft is made small. Therefore, compared with the thing of patent document 1, even if it makes small, it becomes possible to obtain a desired clamping width. In addition, since the pair of sandwiching members is not a wire as seen in Patent Document 2, but is made of a metal plate, it is possible to make the biasing means difficult to see and to simplify the appearance. .
That is, according to this clamping tool, a desired clamping width can be obtained and the appearance can be simplified even if the size is reduced as compared with the prior art.
By the way, as in this pinching tool, when the pair of pinching members are each constituted by a metal plate, and the pinching portion is configured by attaching or covering a cover made of a synthetic resin or rubber having flexibility, the above Patent Document 1 Compared to the case where the pair of sandwiching members (11) are made of synthetic resin and the cover (23) is integrally formed with the pinch body (11) by vulcanization molding of EVA rubber like There is a risk that it will be easy to come out from the pinch.
On the other hand, in the pinching tool according to the present invention, the pinching portion covered with the cover is located in the cover, and a part of the pinching portion is punched into a tongue shape, The tip is punched out toward the shaft side, and the tip is bent in the direction toward the opposite nipping part, and the cover is prevented from coming off and the cover is pressed toward the opposite nipping part. Since it is comprised as a pressing piece which does, the said cover becomes difficult to remove | deviate from a clamping part with the said tongue piece. In addition, it is possible to impart a good clamping force to the object by the pressing force of the tongue piece.
As described above, according to this sandwiching tool, a desired sandwiching width can be obtained and the appearance can be simplified even if it is downsized, and a favorable sandwiching force is imparted to an object to be sandwiched. be able to.
Desirably, the maximum width in the axial direction from the shaft portion to the cover of the pinching member is equal to or greater than the maximum width in the axial direction of the cover.
This makes it difficult for objects to be caught on the cover, making it more difficult for the cover to come out of the sandwiched portion.
More preferably, the side edge of the sandwiching member and the side edge of the cover are flush with each other.
If it does in this way, it will become difficult to catch an object on a cover, and it will become difficult to remove a cover from a pinching part, and it can also improve an appearance.
Preferably, a connection member connected to the shaft portion for suspending the clip tool is provided, and the connection member integrally connects the ring portions with a pair of ring portions through which the shaft portion is inserted. And the maximum length from the shaft center of the shaft portion to the arch portion is longer than the minimum length from the shaft center of the shaft portion to the inner surface of the sandwiching member. The configuration.
If comprised in this way, since the axial part of a clamping tool can be suspended at two points by a pair of ring part of a connection member, a clamping tool can be suspended in the stable state. Since the pair of ring portions are connected by an inverted U-shaped arch portion, the shaft portion of the clip tool is connected to the pair of rings of the connection member as described above by suspending the arch portion with a single suspension member. It is possible to suspend in a stable state at two points. In addition, since the maximum length from the shaft center of the shaft portion to the arch portion is longer than the minimum length from the shaft center of the shaft portion to the inner surface of the sandwiching member, the rotation of the connecting member around the shaft is The arch portion is regulated by contacting the inner surface of the sandwiching member. Therefore, the arch portion of the connecting member does not go around to the opposite side of the shaft, and the pinching tool can be satisfactorily suspended.

Hereinafter, embodiments of a clip tool according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, this pinching tool 1 includes a pair of pinching members 10 and 10 each having a pinching portion 11 at one end and a knob portion 12 at the other end, and the pair of pinching members 10 and 10 as the pinching portion. 11 and the knob 12 are provided between the pair of pinching members 10 and 10 and are urged toward the side where the pinching portions 11 come into contact with each other. A biasing means 30 and a cover 40 made of a synthetic resin or rubber having flexibility, which is mounted or covered so as to cover the pinching portion 11 of the pinching member 10, are provided.

Each of the pair of sandwiching members 10 is made of a metal plate.
As shown in FIG. 2, the sandwiching member 10 in this embodiment is formed by punching and bending a stainless steel plate having a thickness of about 0.6 mm.
Specifically, a flat plate-like semicircular pinching portion 11 is formed at one end of the stainless steel plate, and a circular knob portion 12 is formed at the other end, and both sides extending from the pinching portion 11 to the knob portion 12 are formed. The pinching member 10 is formed by bending the peripheral portions 12e of the knobs 13 and 13 and the knob 12 so as to rise to the inside (opposite sides of the pair of pinching members 10 and 10 in FIG. 1). The sandwiching member 10 is entirely reinforced by the rising portion (bending portion).

The knob 12 is slightly bent inward so that the finger can be easily applied (see FIG. 2D).
Bearing portions 13L and 13R are integrally formed on both side portions 13. A bearing hole 13h is provided in each of the bearing portions 13L and 13R.

  A part (14) of the sandwiching part 11 located in the cover 40 (covered by the cover 40) is punched into the sandwiching part 11 in a tongue-like shape with the tip 14c facing the shaft part 20 side. 14 is configured as a pressing piece that is bent so that the front end 14c thereof faces toward the opposite sandwiching portion (inside) and prevents the cover 40 from coming off and presses the cover 40 toward the opposing sandwiching portion. It is.

  The cover 40 in this embodiment shown in FIG. 3 is configured in a cap shape made of a synthetic resin (for example, soft EVA resin, elastomer resin, polyethylene, etc.) that is mounted so as to cover the pinched portion 11 of the pinching member 10. However, the cover may be provided so as to integrally cover the sandwiching portion 11. Further, the cover is not cap-shaped and may be provided only inside the pinching portion 11, and at least a part of the cover may abut against the object. The material is arbitrary as long as it is a synthetic resin or rubber having flexibility. As the rubber, for example, natural rubber, synthetic rubber, silicon rubber and the like can be adopted.

  The illustrated cover 40 is a thin and bag-like cap having a thin hole 41 having the same shape as the sandwiching portion 11 into which the sandwiching portion 11 of the sandwiching member 10 is fitted. The sandwiching portion 11 is fitted into the thin hole 41. By being inserted, it is attached to the clip portion 11. As shown in FIG. 1, when the cover 40 is attached to the sandwiching portion 11, the tip 14 c of the tongue piece 14 comes into contact with the inner surface of the cover 40, thereby making it difficult for the cover 40 to be removed from the sandwiching portion 11. .

  In this embodiment, the cover 40 is provided with a stopper other than the tongue piece 14 between the cover 40 and the sandwiching portion 11. 2 and 3, in addition to the tongue piece 14, convex portions 42, 42 provided on both sides of the thin hole 41, and the sandwiching portion 11 so as to engage with the convex portion 42. The recesses 15, 15 provided on both side portions constitute a prevention of the cover 40 from coming off from the sandwiching portion 11.

  The cover 40 shown in FIGS. 1 and 3 has a raised portion 43 on a surface facing the cover 40 facing each other. When the cover 40 is attached to the sandwiching portion 11, the raised portion 43 is pressed from the inside by the tongue piece 14 toward the other cover 40 (see FIG. 1 (i)). Even if the raised portion 43 is not provided, when the cover 40 is attached to the clip portion 11, the portion corresponding to the tongue piece 14 is raised.

  As shown in FIG. 1, the shaft portion 20 can be composed of a shaft (20) using rivets, and the biasing means 30 can be composed of a torsion spring (30) provided around the shaft 20. Both ends 31, 31 of the torsion spring 30 are brought into contact with the inside of the knob portion 12 in the pinching member 10. Thereby, the knob | pick parts 12 are urged | biased by the direction which is expanded, and the clip parts 11 are urged | biased by the direction contact | abutted.

Such a pinching tool can be assembled, for example, as follows.
First, a pair of pinching members 10 each having a cover 40 attached to the pinching portion 11 are prepared, and the pinching members 10 are opposed so that the bearing portions 13L and 13R are overlapped with each other so that the respective bearing holes 13h coincide with each other. At this time, since the pair of sandwiching members 10 have exactly the same shape, the bearing portion 13R of the other sandwiching member 10 is overlapped with the bearing portion 13L of the one sandwiching member 10, and the bearing portion 13R of the one sandwiching member 10 is overlapped. However, in order to prevent the pair of sandwiching members 10 from shifting when viewed from a direction orthogonal to the axial direction (FIG. 1 (c) ( As shown in FIG. 2C, one bearing portion 13R is biased inward in the axial direction (here, the right side in FIG. 2C) and receives the other bearing portion 13L, as shown in FIG. It is made to be able to.

  Next, the urging means 30 is disposed between the pinching members 10, the shafts 20 made of rivets are inserted into the bearing portions 13 L and 13 R and the coil portions 32 of the torsion springs 30, and the tip 21 is crushed so that the shaft 20 The clip 1 can be assembled by preventing it from coming off.

  According to the sandwiching tool 1 as described above, the object (for example, laundry) is placed between the sandwiching portions 11 and 11 by opening and closing the sandwiching portions 11 and 11 by gripping the gripping portion 12 of the pair of sandwiching members 10. , And can be clamped with a clamping force based on the biasing means 30. A cover 40 made of a synthetic resin or rubber having flexibility is attached or covered to the sandwiching portion 11 so as to cover the sandwiching portion 11, so that the cover 40 serves as a slip stopper for the object. , Good clamping state is obtained.

  And this pinching tool 1 has a pair of pinching members 10 each made of a metal plate, and therefore has a thickness t, t ′ around the axis as compared with that of Patent Document 1 (see FIG. 2A). Even if it is made small, it is easy to obtain a desired strength. Therefore, it is possible to obtain a desired clamping width W3 (see FIG. 4A) even if the size is reduced as compared with that of Patent Document 1.

This point will be described with reference to conceptual diagrams shown in FIGS. 4 (b1) to (c2).
Figures (b1) and (c1) show that the heights H and widths W, which are the outer dimensions, are the same, and the thicknesses t2 and t1 around the axis of the pinching member 10 'are different (t2> t1). FIG.
FIGS. 2 (b2) and 2 (c2) are diagrams showing intervals between the pinching portions 11 ′ when the pinching portions 12 ′ of the pinching tools b and c are fully picked up, that is, the maximum holding widths W1 and W2. .
As is apparent from these drawings, if the height H and the width W, which are external dimensions, are the same, the pinch c having a smaller wall thickness around the axis of the pinch member 10 'has a larger maximum pinch width W2. You can see that

In other words, if the wall thickness around the shaft is reduced, the desired clamping width can be easily obtained even if the outer dimensions are reduced.
As can be seen from the above, in the pinching tool 1 of the present embodiment, the pair of pinching members 10 are each made of a metal plate, and the thicknesses t and t around the axis are compared with those of the above-mentioned Patent Document 1. Since a desired strength can be easily obtained even if 'is small (see FIG. 2A), the desired clamping width W3 (see FIG. 4A) can be obtained even if the size is reduced compared to that of Patent Document 1. It becomes possible.

Further, in the pinching tool 1 of this embodiment, since the pair of pinching members 10 are made of a metal plate instead of a wire as seen in Patent Document 2, for example, as shown in FIG. The urging means 30 can be made difficult to see and the appearance can be simplified.
That is, according to this clamping tool 1, compared with the prior art, a desired clamping width W1 can be obtained even if the size is reduced, and the appearance can be simplified.

  By the way, for example, like this pinching tool 1, a pair of pinching members 10 are each made of a metal plate, and the pinching portion 11 is provided with a cover 40 made of a synthetic resin or rubber having flexibility. The pair of pinching members (11) are each made of synthetic resin, and the cover (23) is integrally formed with the pinch body (11) by vulcanization of EVA rubber, as in the above-mentioned Patent Document 1. In comparison, the cover 40 may be easily removed from the sandwiching portion 11.

On the other hand, in the pinching tool 1 of this embodiment, the pinching portion 11 covered with the cover 40 is located in the cover 40, and a part (14) of the pinching portion 11 is punched into a tongue shape. The tongue piece 14 is punched so that the tip end 14c is directed toward the shaft portion 30 side, and the tip end 14c is bent in the direction toward the sandwiching portion side (inner side) opposite to each other. Since the cover 40 is configured as a pressing piece that presses the cover 40 toward the opposite sandwiching portion, the cover 40 is difficult to be removed from the sandwiching portion 11 by the tongue piece 14. In addition, it is possible to impart a good clamping force to the object by the pressing force of the tongue piece 14.
As described above, according to the sandwiching tool 1, a desired sandwiching width can be obtained and the appearance can be simplified even if it is downsized, and a favorable sandwiching force is imparted to a sandwiched object. can do.

The maximum axial width W4 (see FIG. 1D) from the shaft portion 30 of the sandwiching member 10 to the cover 40 may be equal to or greater than the maximum axial width W5 of the cover 40. desirable.
If it does so, since it will become difficult to catch on the corner | angular part 40c of the cover 40, the cover 40 will become still more difficult to remove from the clamping part 11. FIG.
In this embodiment, as shown in FIG. 1D, the side edge 10e of the pinching member 10 and the side edge 40e of the cover 40 are flush with each other.
If it does in this way, it will become difficult for a thing to get caught in the corner | angular part 40c of the cover 40, and it will become difficult to remove the cover 40 from the clamping part 11, and it can also improve an external appearance.

FIG. 5 is a diagram showing another embodiment.
The point of difference between this embodiment and the above-described embodiment is that it has a connecting member 50 connected to the shaft portion 20 for suspending the holding device 1, and the other points are different. Absent.
The connecting member 50 has a pair of ring parts 51, 51 through which the shaft part 20 is inserted, and an inverted U-shaped arch part 52 that connects the ring parts 51 together, as shown in FIG. As shown, the maximum length L2 from the shaft center 20c of the shaft portion 20 to the arch portion 52 is longer than the minimum length L1 from the shaft center 20c of the shaft portion 20 to the inner surface 16 of the sandwiching member 10.

If comprised in this way, since the axial part 20 of the clamping tool 1 can be suspended at two points by a pair of ring parts 51 and 51 of the connection member 50, the clamping tool 1 can be suspended in the stable state. Since the pair of ring portions 51, 51 are connected by an inverted U-shaped arch portion 52, the arch portion 52 is sandwiched as described above by suspending the arch portion 52 with a single suspension member 61 as shown in the figure, for example. The shaft portion 20 of the tool 1 can be suspended in a stable state at two points by the pair of ring portions 51, 51 of the connecting member 50. Moreover, since the maximum length L2 from the axis 20c of the shaft portion 20 to the arch portion 52 is longer than the minimum length L1 from the shaft center 20c of the shaft portion 20 to the inner surface 16 of the sandwiching member 10, the connecting member 50 The rotation around the axis is restricted by the arch portion 52 coming into contact with the inner surface 16 of the sandwiching member 10 as indicated by a virtual line in FIG. Therefore, the arch portion 52 of the connecting member 50 does not wrap around to the opposite side (downward in the drawing) of the shaft 20, and the clip 1 can be satisfactorily suspended.
In the illustrated example, the suspension member 61 is further connected to a frame (for example, a frame of a clothes drying tool) 63 using another suspension member 62, but the suspension member 61 may be directly connected to the frame 63. it can.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
