Description

[Technical field]

[0001] This invention relates to a clamping device for attaching metal fittings to a purse, in which one rotating member and the other rotating member are arranged so that they can rotate around a fulcrum at the midpoint where they contact each other, and the tips of the one rotating member and the other rotating member can clamp an object by the biasing force of a rotation-limiting spring. [Background technology]

[0002] Conventionally, a sewing clip used to temporarily hold fabric in place when sewing or doing needlework has been proposed which has a lower member, an upper member, and a spring member which applies a biasing force to the lower and upper members, and in which the openings of the lower and upper members are provided with multiple pairs of recesses and protrusions which fit together when the openings are closed (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Design Registration No. 1569734 (front view) Summary of the Invention [Problem to be solved by the invention]

[0004] The problem that we aim to solve with regard to clamps for attaching metal fittings to purses is that while conventional sewing clips are suitable for simply temporarily fastening pieces of fabric together, it is difficult to properly temporarily fasten the metal fittings and fabric when pushing the fabric into the inside of the metal fittings with a U-shaped cross section, such as when joining the metal fittings with a U-shaped cross section that make up the opening of the purse to a sheet material (fabric) such as fabric or leather that makes up the bag part of the purse.

[0005] Therefore, an object of the present invention is to provide a clamping device for attaching metal fittings to a purse, which can provide a temporary fixation method in an efficient manner when adhesively fastening objects that are made of different materials and shapes, such as the metal of the purse fittings and the fabric of the purse bag. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention has the following configuration. According to one embodiment of the clamping device for attaching metal fittings to a purse according to the present invention, one rotating member and the other rotating member are arranged to be able to rotate around a mutually contacting midway portion as a rotation axis, and the tip ends of the one rotating member and the other rotating member can clamp an object by the biasing force of a rotation restricting spring, and the clamping device for attaching metal fittings to a purse is used for temporarily fastening a metal fitting of the purse having a U-shaped cross section that constitutes the opening of the purse to an edge portion of a sheet-like member that constitutes the bag portion of the purse, and a clamping claw portion is provided at the tip end of the one rotating member, which is formed in a spatula-like shape protruding in the clamping direction and is capable of abutting at its tip against the object to apply pressure, and the clamping claw portion advances toward an inner bottom portion on the inside of the metal fitting of the purse having a U-shaped cross section and clamps the object at the inner bottom portion. one of the rotating members has a thickness in the front-to-rear direction, which is the longitudinal direction of the one of the rotating members, and a length protruding in the clamping direction, so that the edge portion of the sheet-like member can be temporarily fixed in a state in which it is pressed and compressed together with the string member, and a pressure-receiving surface is provided at the tip of the other of the rotating members, which abuts and clamps against an outer curved surface portion that is on the outside of the metal fittings of the purse and is a curved portion having a U-shaped cross section, and which receives the clamping pressure from the clamping claw portion, the pressure-receiving surface is formed longer forward than the front-to-rear tip of the clamping claw portion, the clamping claw portion protrudes in the rotation direction from a rotation plane defined as a plane that rotates through the rotation axis, and is bent at an acuter angle than the tip of the one of the rotating members bent at a right angle in the rotation direction, and the pressure-receiving surface is provided by an anti-slip member made of rubber.

[0007] According to one form of the clamping device for attaching metal fittings to a purse of the present invention, the left and right corners of the tip of the clamping claw portion are cut out so as to taper toward the tip of the clamping claw portion.

[0008] According to this, since the corners of the tip of the clamping claw are rounded, the tip of the clamping claw can be inserted properly and easily into the inside of the metal fitting of the purse, and the pressing force of the tip of the clamping claw can be concentrated. Therefore, it is possible to improve the workability and the temporary fastening effect.

[0009] According to one form of the clamping device for attaching metal fittings to a purse of the present invention, the pressure-receiving surface can be characterized in that a cap-shaped anti-slip member made of rubber is fitted onto the tip end of the other rotating member from the tip side of the tip end.

[0010] This allows the pressure receiving surface to be appropriately and easily formed at the tip of the other rotating member. That is, the non-slip member made of rubber is easy to attach because it is cap-shaped, is durable and does not easily come off when in use, and can be appropriately held in place by abutting against the outside of the metal fitting of the purse to prevent slipping. Effect of the Invention

[0011] The clamping device for attaching metal fittings to a purse of the present invention has the particularly advantageous effect of being able to provide a rational temporary fixation when adhesively fastening objects made of different materials and shapes, such as metal fittings and fabric, to a purse.

[0013] Hereinafter, examples of the clamping device for attaching metal fittings to a purse according to the present invention will be described in detail with reference to the drawings (FIGS. 1 to 6).

[0014] The clamping device for attaching metal fittings to a purse according to the present invention has a basic configuration like a clothes peg, in which one rotating member 10 and the other rotating member 20 are arranged so that they can rotate around their mutually contacting midpoint as a fulcrum (rotation axis 15 (see Figure 9)), and the tips of the one rotating member 10 and the other rotating member 20 are arranged so that they can clamp an object by the biasing force of a rotation-limiting spring 30 (elastic spring member).

[0015] In this embodiment, a convex fulcrum portion 12 that protrudes from the spherical surface as a fulcrum is provided at the midpoint of one rotating member 10, and a concave fulcrum portion 22 that is recessed into the spherical surface as a fulcrum is provided at the midpoint of the other rotating member 20, and the convex fulcrum portion 12 is assembled in a fitted state into the concave fulcrum portion 22, so that one rotating member 10 and the other rotating member 20 can be rotated so that their tips move toward and away from each other. To operate the rotation, one operating portion 13 at the rear end side of one rotating member 10 and the other operating portion 23 at the rear end side of the other rotating member 20 can be pinched with fingers.

[0016] In the clamping device for attaching metal fittings to a purse according to the present invention, a clamping claw 11 is provided at the tip of one of the rotating members 10, which is formed in a spatula-like (flat plate-like) shape protruding in the clamping direction and can apply pressure by abutting the tip against an object. In this embodiment, the clamping claw 11 is provided by bending the tip of one of the rotating members 10. The tip of one of the rotating members 10 has a required width (about 10 mm in this embodiment) in the left-right direction (width direction relative to the longitudinal direction of one of the rotating members 10) perpendicular to the rotation direction, protrudes in a thin spatula-like shape in the thickness direction (front-rear direction), and is also tapered (tapered) in the width direction (left-right direction) so that the tip is in the shape of the upper side of a trapezoid with a pair of corners of a rectangle removed. In addition, the tip of the clamping claw portion 11 does not need to be sharp, and may be linear extending in the left-right direction with the required width (thickness) in the front-to-back direction as shown in the drawing, with rounded corners, as long as it has a shape that applies pressure in a concentrated manner, at least compared to the pressure-receiving surface 21 of the other rotating member 20 described later.

[0017] Furthermore, in the clamping device for attaching metal fittings to a purse according to the present invention, the tip of the other rotating member 20 serves as a surface that abuts against and clamps the object, and also serves as a pressure-receiving surface 21 that receives the clamping pressure from the clamping claws 11. In this embodiment, the pressure-receiving surface 21 is a simple, smooth, flat rectangular surface, but this is not limited to this, and it is of course possible for the surface to be a concave surface that is gentler than the convex curved surface when the surface of the object to be abutted is a convex curved surface, or to have unevenness formed to prevent slipping, so that the object does not slip easily.

[0018] This provides a special advantageous effect of enabling rational temporary fastening when, for example, objects made of different materials, such as metal fittings and fabric (cloth or sheet material), are to be fixed with an adhesive. That is, the tip of one of the rotating members 10 is a clamping claw 11, which is shaped to concentrate pressure, and depending on the conditions of use, the object can be appropriately clamped and temporarily fastened, and the work efficiency can be significantly improved when making specific items that contain fabric or sheet material, such as a clasp 50 (see FIG. 5), in handicrafts.

[0019] In this embodiment, the clamping claw portion 11 is flat and has a thickness and length that allows it to enter inside the metal fitting 51 (see FIG. 5) of the purse 50, which has a U-shaped cross section. As a result, as shown in the cross section of FIG. 6, when manufacturing the purse 50, the string member 53 can be pressed down by the force of the rotation restriction spring 30 so as to hold the fabric 52 and the twisted string member 53 (twisted string) in a pressed state inside the metal fitting 51 to which adhesive 54 is applied, and suitably temporarily fixed.

[0020] The process for attaching metal fitting 51 to purse 50 involves using spatula 60 to push string member 53 together with fabric 52 into the inside of metal fitting 51 containing adhesive 54, so that they bite into the inside, as shown in Fig. 7. Then, by using a clamp for attaching metal fittings to a purse according to the present invention to fasten the inserted portion of fabric 52 and string member 53, as shown in Figs. 5 and 6, fabric 52 and string member 53 can be prevented from slipping out, and the insertion and adhesion work can be carried out smoothly.

[0021] In this embodiment, the pressure-receiving surface 21 is provided with an anti-slip member 25. A rubber material (e.g., silicon rubber) can be used as the anti-slip member 25, and as shown in the drawings, it may be provided so as to form a layer on the pressure-receiving surface 21, or it may be attached so as to be wrapped around the tip of the other rotating member 20, and may be fixed appropriately. This can prevent the object (engaged object) from slipping as much as possible, and the object can be appropriately clamped.

[0022] In this embodiment, the rotation restricting spring 30 is provided by forming a plate-like metal elastic member into a substantially U-shape. This allows the conventionally used rotation restricting spring 30 to be used to appropriately configure the clamping device for attaching metal fittings to a purse according to the present invention.

[0023] Next, with reference to Figs. 8 and 9, an embodiment in which a cap-shaped non-slip member 25A made of rubber is used in a clamping device for attaching metal fittings to a purse according to the present invention will be described.

[0024] In this embodiment, similarly to the above-described embodiment, one rotating member 10 and the other rotating member 20 are arranged so as to be rotatable about their mutually contacting midway portion as a rotation axis 15 (see FIG. 9), and the tip portions of one rotating member 10 and the other rotating member 20 can clamp an object by the biasing force of a rotation restricting spring (not shown), forming a clamping device for attaching a metal fitting to a purse that is used for temporarily fastening a metal fitting 51 of a purse with a U-shaped cross section that constitutes the opening of the purse to an edge portion 52a of a sheet-like member 52 that constitutes the bag portion (fabric 52) of the purse.

[0025] Also, similar to the above-described embodiment, a clamping claw portion 11 is provided at the tip of one of the rotating members 10, which is formed in a spatula-like shape protruding in the clamping direction and can abut the object at its tip to apply pressure, and the clamping claw portion 11 has a thickness in the front-to-rear direction, which is the longitudinal direction of the one of the rotating members 10, and a length protruding in the clamping direction so that the clamping claw portion 11 can enter toward the inner bottom portion 51a on the inside of the metal fitting 51 of the purse, which has a U-shaped cross section, and temporarily secure the edge portion 52a of the sheet-like member 52 at the inner bottom portion 51a by pushing and pressing it together with the string member 53.

[0026] Also, similarly to the above-described embodiment, a pressure-receiving surface 21 is provided at the tip of the other rotating member 20, which is a surface that abuts against and clamps the outer curved surface portion 51b, which is a curved portion having a U-shaped cross section on the outside of the metal fitting 51 of the purse, and which receives the clamping pressure from the clamping claw portion 11, and the pressure-receiving surface 21 is formed longer forward than the front-rear direction tip of the clamping claw portion 11. The pressure-receiving surface 21 is provided by an anti-slip member 25A made of rubber.

[0027] In the embodiment shown in FIG. 8, the pressure-receiving surface 21 is formed by fitting a cap-shaped anti-slip member 25A made of rubber onto the tip portion of the other rotating member 20 from the tip side of the tip portion.

[0028] This makes it possible to appropriately and easily form the pressure-receiving surface 21 provided at the tip of the other rotating member 20. That is, this rubber anti-slip member 25A has a cap shape, so it is easy to attach just by putting it on, is durable and does not easily come off when in use, and appropriately abuts against the outside of the metal fitting 51 of the purse, and can hold the metal fitting 51 of the purse without slipping due to elastic deformation and frictional force.

[0029] Further, as in the above-mentioned embodiment, as is clear from Fig. 9, the clamping claw portion 11 is provided in a form that protrudes in the rotation direction from a rotation surface defined as a plane that rotates through the rotation axis 15, and is bent at an acute angle α, rather than a form in which the tip of one of the rotating members 10 is bent at a right angle in the rotation direction. That is, the rotation surface 10a, which is a flat surface that passes through the rotation axis 15 and extends to the base of the clamping claw portion 11, and the bending surface 11a, which is virtually defined as a flat surface that passes through the center of the clamping claw portion 11 bent from the rotation surface 10a, intersect at an acute angle α in a claw-like shape. Note that this angle is about 65 degrees in the embodiment shown in Fig. 9, but is not limited to this and may be any acute angle, and may be set appropriately within a range of, for example, 55 degrees to 80 degrees, more preferably 60 degrees to 75 degrees.

[0030] According to the configuration in which the clamping claw portion 11 is bent at an acute angle α, as shown in FIG. 6 etc., the tip of the clamping claw portion 11 comes into contact with the object (string member 53 in the example configuration in FIG. 6) and applies a clamping pressure in a direction that pulls the object inward, and the anti-slip effect is enhanced by the elastic deformation and frictional resistance of the anti-slip member 25 made of rubber that receives the clamping pressure, resulting in the particularly advantageous effect that the temporary fastening operation can be smoothly performed when attaching the metal fittings 51 of the purse 50.

[0031] 10 showing an embodiment of the present invention, the clamping claws 11 are bent at an acute angle, so that the tip of the clamping claws 11 is easily pressed so as to crush the sheet-like member 52, string member 53, and other members straight into the inner bottom 51a of the purse metal fitting 51, and the pressure-receiving surface 21 is easily pressed against the center of the arc of the outer curved surface 51b, which is a curved portion having a U-shaped cross section on the outside of the purse metal fitting 51. Therefore, according to the present invention, the sheet-like member 52 can be temporarily fixed appropriately and reliably.

[0032] In contrast, in FIG. 11 showing a comparative example, the clamping claw portion 11 is bent at a right angle, and the tip of the clamping claw portion 11 is not at an angle that makes it easy to push the string member 53 etc. straight into the depths of the inner bottom portion 51a of the purse metal fitting 51, and the pressure-receiving surface 21 is not in a shape that can abut against the center of the arc of the outer curved surface portion 51b.

[0033] Furthermore, according to the present invention, a clamping force can be applied in the direction in which the tip of the clamping claw portion 11 sweeps in, and as a result, a component force of the clamping force (pressing force) acts via the metal fittings 51 of the purse 50 in the direction in which the cap-shaped rubber anti-slip member 25A is fitted into the tip of the rotating member 20, so that the cap-shaped rubber anti-slip member 25A is less likely to come off, allowing for stable operation.

[0034] 8, like the above-mentioned embodiment, the left and right corners of the tip of the clamping claw 11 are cut out so as to taper toward the tip of the clamping claw 11. That is, in this embodiment, a tip notch 11b (see FIG. 8) is formed on both the left and right sides of the tip of the clamping claw 11. Note that, although this tip notch 11b has a linear cut shape, this is not limited thereto, and it is of course possible for it to have a rounded cutout shape like the tip of the spatula 60 shown in FIG.

[0035] According to this, since the corners of the tip of the clamping claw portion 11 are rounded, it is difficult to get caught, and the tip of the clamping claw portion 11 can be properly and easily inserted into the inside of the metal fitting of the purse, and the pressing force of the tip of the clamping claw portion 11 can be concentrated. Therefore, it is possible to improve the workability, and since the object can be firmly clamped, the temporary fastening effect can be improved.

[0036] Also, a process for temporarily fixing the metal fitting 51 of the purse to the edge portion 52a of the sheet-like member 52 will be described in relation to the string member 53. Basically, when attaching the metal fitting 51 of the purse to the pouch portion of the purse (the edge portion 52a of the sheet-like member 52), the edge portion 52a is clamped by the clamping claw portion 11 and the pressure-receiving surface 21 via the string member 53 disposed inside the metal fitting 51 of the purse, thereby temporarily fixing the edge portion 52a to the inner bottom portion 51b of the metal fitting 51 of the purse.

[0037] Furthermore, as shown in Figure 6, etc., the sheet-like member 52 can be more securely attached by being temporarily fastened to the inner bottom 51b of the purse metal fitting 51 by bending the end (edge ​​portion 52a) of the sheet-like member 52 along the outer periphery of the string member 53 and the inner bottom 51b of the purse metal fitting 51 so that the end (edge ​​portion 52a) is folded back at the temporarily fastened position.

[0038] Furthermore, since the string member 53 is of a thickness (see Figure 6, etc.) that allows the sheet-like member 52 to be sandwiched between the inner bottom 51b of the purse metal fittings 51 so as to fill the closed space of the purse metal fittings 51 when the purse metal fittings 51 are crushed (crimped) with pliers or the like to close the opening (finally, when the purse metal fittings 51 are fixed to the edge portion 52a of the sheet-like member 52) to attach the purse metal fittings 51 to the bag portion of the purse (edge ​​portion 52a of the sheet-like member 52), the attachment can be made even more secure.

[0039] We have explained above that the clamping device for attaching metal fittings to a purse according to the present invention is preferably used when fastening metal fittings 51 of a purse 50, but it goes without saying that it is not limited to this and can be appropriately applied to other purposes as well.

[0040] Although the present invention has been described above in various preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. [Explanation of symbols]
