[0010] (Configuration included in the present invention) The present inventors have conducted extensive research into the clamping tool according to the present invention and have come to the following findings.

[0011] One aspect of the present invention is a clamping tool comprising a base, clamping portions extending continuously in the same direction from both ends of the base, and bulging portions disposed on the clamping portions and protruding toward the opposing clamping portions, the opposing bulging portions being arranged asymmetrically with respect to a center line extending in the longitudinal direction of the clamping portions.

[0012] With this configuration, it is possible to prevent damage to the object to be clamped when the object is clamped.

[0013] In the clamping tool according to one aspect of the present invention, the bulging portion may be configured to be able to press an object to be clamped that is inserted between the opposing clamping portions in a direction perpendicular to the center line.

[0014] With this configuration, it is possible to prevent the object to be clamped from falling off the clamping portion.

[0015] In the clipping tool according to one aspect of the present invention, the opposing bulging portions may have their peaks arranged asymmetrically with respect to the center line.

[0016] With this configuration, the tops of the opposing bulging portions do not come into contact with each other, so it is possible to avoid pressing the object to be clamped from both sides.

[0017] In the clamping tool according to one aspect of the present invention, the bulging portion may have a closed hollow between the raised edge and the clamping portion.

[0018] With this configuration, the bulging portion has elasticity, and it is possible to reduce the possibility of damaging the surface of the object to be clamped when the object is clamped.

[0019] In the clamping tool according to one aspect of the present invention, the bulging portion may be formed in a claw shape that bulges toward the opposing clamping portion.

[0020] With this configuration, the bulging portion has elasticity, and it is possible to reduce the possibility of damaging the surface of the object to be clamped when the object is clamped.

[0021] In the clamping tool according to one aspect of the present invention, the clamping portion may further include a groove portion having a shape corresponding to the tip of the protruding portion.

[0022] With this configuration, when the bulging portion comes into contact with the object to be clamped, it can bend to such an extent that the tip of the bulging portion can enter the groove portion.

[0023] In the clipping tool according to one aspect of the present invention, the bulging portion may be formed so that the top thereof extends beyond the center line.

[0024] With this configuration, the bulging portion curves the object to be clamped as it enters the clamping portion, thereby preventing the object from falling out.

[0025] In one aspect of the clamping tool of the present invention, the bulging portions may be arranged in multiple positions along the longitudinal direction of the clamping portion, and the distance between the peaks of opposing bulging portions in a direction perpendicular to the center line may be longer toward the tip of the clamping portion.

[0026] With this configuration, the pressing force from the bulging portion increases toward the tip of the clamping portion, making it possible to effectively prevent the clamped object from falling off.

[0027] In the clamping tool according to one aspect of the present invention, the opposing bulging portions may be configured not to come into contact with each other.

[0028] With this configuration, it is possible to prevent the surface of the object to be clamped from being damaged by the bulging portion.

[0029] In one aspect of the clipping tool of the present invention, the base may be U-shaped in plan view, with the distance therebetween in a direction perpendicular to the center line gradually decreasing from the middle portion to the end portion.

[0030] With this configuration, the base portion can effectively maintain the clamping portions at a predetermined distance from each other.

[0031] Hereinafter, each embodiment of the present invention will be described in detail with reference to the drawings. Note that the same components or components are denoted by the same reference numerals, and redundant description thereof will be omitted.

[0032] The present invention is a clamping tool capable of clamping an object, and the object to be clamped includes an article made of an easily deformable material such as cloth, paper, leather, or synthetic resin products. In each embodiment shown below, a clamping tool 1, which is an example of the present invention, is a clamping tool 1 capable of clamping an article with an opening, such as a bag or a pouch. The clamping tool 1 may be configured in a clip shape or a pinch (clip) shape.

[0033] In each embodiment of the present invention, unless otherwise defined, the direction in which the clamping portion 3 extends is referred to as the longitudinal direction, and the direction perpendicular to the longitudinal direction in a horizontal plane is referred to as the width direction. The direction perpendicular to the horizontal plane is referred to as the height direction, and the surface of the clamping device 1 when viewed from the direction perpendicular to the horizontal plane is referred to as the plane.

[0034] (First embodiment) A first embodiment of the present invention will be described. Fig. 1 is a diagram showing an example of the configuration of a clip 1 in the first embodiment. In the example shown in Fig. 1, the clip 1 is a long, thin U-shaped clip.

[0035] The clamping tool 1 includes a base 2 and clamping portions 3 extending continuously from both ends of the base 2. The clamping tool 1 also includes bulging portions 4 disposed on the clamping portions 3.

[0036] The clamp 1 is made of an elastic material, for example, synthetic resin. The base 2 and clamping part 3 may be integrally formed, or may be separably connected.

[0037] The base 2 is a member that bulges outward and bends, and as an example, may be a member that is curved in a U-shape in plan view. The base 2 is configured to have an opening in the width direction, and the opening has elasticity that allows it to expand and contract in the width direction.

[0038] The clamping portions 3 extend continuously from both ends of the base 2. The clamping portions 3 extend in approximately the same longitudinal direction from both ends of the base 2. In the clamping tool 1, the clamping portions 3 extending from both ends of the base 2 are arranged facing each other in approximately the same direction.

[0039] The clamping tool 1 can clamp an object by inserting it between the opposing clamping portions 3. In the first embodiment, the opposing clamping portions 3 may have elasticity to the extent that they can expand and contract the distance between them in the width direction.

[0040] The bulging portions 4 are disposed on the clamping portions 3 and are configured to bulge toward the opposing clamping portion 3. In the example shown in FIG. 1, the same number of bulging portions 4 are disposed on each of the opposing clamping portions 3. The surfaces of the bulging portions 4 may be formed smooth, which makes it possible to avoid damaging the surface of the object to be clamped.

[0041] In the clamping tool 1 shown in the first embodiment, the opposing bulging portions 4 are arranged asymmetrically with respect to a center line L1 extending in the longitudinal direction of the clamping portions 3. The center line L1 is a line that is equidistant from each of the opposing clamping portions 3 in a plan view and extends in the longitudinal direction. In the example shown in FIG. 1, the peaks of the opposing bulging portions 4 are not in contact with each other and are arranged asymmetrically with respect to the center line L1. This configuration makes it possible to prevent damage to the object to be clamped when the object is clamped.

[0042] In the first embodiment, the top of the bulging portion 4 refers to the portion where the distance between the opposing sandwiching portion 3 in the width direction is the shortest.

[0043] The clip 1 exemplified in the first embodiment may further include a reinforcing portion 6 that is disposed inside the base 2 and is capable of suppressing the expansion of the base 2 in the width direction. The reinforcing portion 6 is configured to suppress the distance between the tips of the base 2 from expanding in the width direction.

[0044] The reinforcing portion 6 is configured to connect opposing sides of the base 2. The reinforcing portion 6 may be formed integrally with the base 2, or may be configured to be separable. In the example shown in FIG. 1, the reinforcing portion 6 is formed integrally inside the base 2 and configured as a plate that connects opposing sides of the base 2 to the bottom. Alternatively, the reinforcing portion 6 may be made of an elastic body such as a spring or rubber, and connects opposing sides of the base 2 to each other.

[0045] Fig. 2 is a plan view showing an example of the configuration of the clamping tool 1 in the first embodiment. The opposing clamping portions 3 shown in Fig. 2 extend substantially parallel to each other in the longitudinal direction. The clamping portions 3 may be configured so that their tips extend outward. With this configuration, when an object to be clamped is inserted through an opening, it is possible to avoid the tip of the clamping portion 3 hitting the object and hindering its insertion.

[0046] Alternatively, the clamping units 3 may be configured so that their tips are close to each other. With this configuration, the tips of the opposing clamping units 3 can clamp the object to be clamped with a strong force.

[0047] 2, the distance of the base 2 in the direction perpendicular to the center line gradually decreases from the middle to the tip. With this configuration, the base 2 narrows toward the tip, so that when an object to be clamped is clamped by the clamping tool 1, the opposing clamping portions 3 can be effectively prevented from expanding in the width direction.

[0048] The bulging portions 4 are respectively disposed on the inside of the opposing clamping portions 3. The bulging portions 4 rise toward the opposing clamping portions 3. In the example shown in Fig. 2, the bulging portions 4 rise in a curved manner toward the opposing clamping portions 3, and the tops rise beyond the center line L1.

[0049] In the example shown in Fig. 2, multiple bulging portions 4 are arranged on each of the opposing clamping portions 3. The pair of bulging portions 4 are arranged asymmetrically with respect to the center line L1. In the example shown in Fig. 2, the pair of bulging portions 4 are arranged at different positions in the longitudinal direction so as not to abut against each other. With this configuration, the object to be clamped passes between the opposing bulging portions 4 and enters in the direction of the base portion 2.

[0050] The bulging portions 4 are configured to be able to press an object to be clamped that is inserted between the opposing clamping portions 3 in a direction perpendicular to the center line L1. In the example shown in FIG. 2, the pair of bulging portions 4 are arranged so as to be offset from each other in a plan view. With this configuration, the object to be clamped advances toward the base portion 2 while bending in a wavy manner in the width direction. This makes it possible to prevent the object to be clamped from falling out of the clamping tool 1.

[0051] 2, the bulging portion 4 rises while curving from one clamping portion 3 toward the opposing clamping portion 3, and its apex is formed beyond the center line L1. The apex of the bulging portion 4 is formed close to the opposing clamping portion 3 beyond the center line L1, and its tip is disposed at a position closer to the base end than the center line L1.

[0052] In the example shown in Fig. 2, the peaks of the opposing bulging portions 4 are arranged asymmetrically with respect to the center line L1. The opposing bulging portions 4 are configured so that the distances from the base end of the clamping portion 3 to the peaks in the direction perpendicular to the center line L1 are approximately the same. The opposing bulging portions 4 are configured so that an object to be clamped can be inserted between them without coming into contact with each other.

[0053] The bulging portion 4 is made of an elastic material such as an elastic body including rubber or resin. In the example shown in FIG. 2, the bulging portion 4 is configured in a curved plate shape when viewed from above. The bulging portion 4 may also be configured in a claw shape. The tip of the bulging portion 4 points toward the base end of the clamping portion 3. This configuration makes it possible to prevent the tip of the bulging portion 4 from getting caught on the object to be clamped.

[0054] In the clamping tool 1 shown in the first embodiment, the bulging portion 4 rises from one clamping portion 3, bulges and curves toward the opposing clamping portion 3, and the tip points toward the base portion 2. The bulging portion 4 is configured to be thinner than the clamping portion 3 in a plan view.

[0055] In the clamping tool 1 shown in the first embodiment, the distance between the tops of the opposing bulging portions 4 in the direction perpendicular to the center line L1 increases toward the tip of the clamping portion 3. As shown in Fig. 2, a plurality of bulging portions 4 are provided on each of the opposing clamping portions 3.

[0056] The distance between the peaks of the opposing bulges 4 in the direction perpendicular to the center line L1 is configured to increase toward the tip. In Figure 2, the distance P1 between the peaks of the opposing bulges 4 on the side farther from the base 2 in the longitudinal direction is longer than the distance P2 between the peaks of the opposing bulges 4 on the side closer to the base 2.

[0057] That is, the opposing bulging portions 4 on the far side from the base 2 have their tops closer to the opposing clamping portions 3 than the opposing bulging portions 4 on the closer side to the base 2, with the tops crossing the center line L1. With this configuration, it is possible to prevent the tip of the clamping tool 1 from expanding in the width direction when the object to be clamped passes between the opposing bulging portions 4 near the tip and enters toward the base 2. By preventing the tip of the clamping tool 1 from expanding in the width direction, it is possible to prevent the clamping tool 1 from falling off the object to be clamped.

[0058] Fig. 3 is a diagram showing an example of how to use the clamping tool 1 in the first embodiment. In the example shown in Fig. 3, the clamping tool 1 clamps an opening 52 of a bag 50, which is an example of an object to be clamped.

[0059] For example, when shopping at a supermarket or other retail store, it is now common for customers to bring their own bag or bag to store their purchases in. The customer places the items they want to purchase in a basket provided by the retail store, then pays for them at the end. After paying, the customer places the purchased items in the bag or bag they brought with them.

[0060] When carrying bag 50 while shopping in a store, if opening 52 is left open and the person moves around the store, store staff may suspect that the person is shoplifting by placing unpaid items in bag 50. Furthermore, with opening 52 open, it is extremely easy to place unpaid items in the bag, which may easily induce shoplifting.

[0061] Therefore, by clamping the opening 52 of the bag 50 with the clamping tool 1, the opening 52 of the bag 50 can be closed. With the aim of eliminating the situation where it is easy to insert an item through the opening 52, the clamping tool 1 clamps the opening 52 with enough force to close it. This makes it possible to close the opening 52 while preventing the bag 50 from being damaged by the clamping tool 1.

[0062] 3, clamping tool 1 clamps opening 52 from above with clamping portion 3. Bulging portion 4 abuts against and presses against the fabric of bag 50. Because clamping tool 1 clamps opening 52 from above, there is little risk of clamping tool 1 falling off bag 50 even if bag 50 is not clamped with great force.

[0063] Preferably, the clamping tool 1 clamps the center or the vicinity of the opening 52. By clamping the center or the vicinity of the opening 52, it becomes difficult to open the opening 52 widely.

[0064] 4 is a diagram showing an example of how to use the clamping tool 1 in the first embodiment. When the opening 52 of the bag 50 is clamped with the clamping tool 1, the upper end of the bag 50 is inserted through the opening of the clamping part 3.

[0065] The upper end of the bag 50 is advanced toward the base 2, passed between the bulging portions 4, and clamped by the clamping portion 3. The bag 50 is pressed by the bulging portions 4 while advancing, and therefore bends according to the shape of the bulging portions 4 as it heads toward the base 2.

[0066] The opposing bulging portions 4 are arranged asymmetrically with respect to the center line L1 so that their peaks do not come into contact with each other. When the bag 50 is inserted into the clamping portion 3, the peaks of the bulging portions 4 do not pinch the bag 50 from both sides, so it is possible to avoid pinching the surface of the bag 50 too hard and damaging it.

[0067] The user may bring the upper end of bag 50 close to base 2 and insert bag 50 until it reaches approximately the vicinity of reinforcing portion 6. Bag 50 is clamped between clamping portions 3 so that it undulates in a plan view according to the shape of bulging portion 4. In this way, the frictional force at the contact surfaces of bulging portion 4 and bag 50 can prevent bag 50 from coming loose from the clamped state.

[0068] (Second embodiment) Next, a second embodiment of the present invention will be described. In the second embodiment, the clamping portion 3 has a groove portion 10 shaped to correspond to the tip of the bulge portion 4. By fitting a part or all of the tip of the bulge portion 4 into the groove portion 10, it is possible to prevent the tip of the bulge portion 4 from getting caught on the surface of the bag 50 when the bag 50 is pulled out of the clamping tool 1.

[0069] 5 is a diagram showing an example of the configuration of the clamping tool 1 in the second embodiment. The bulging portion 4 bulges and curves toward the opposing clamping portion 3, and the tip portion is again close to the clamping portion 3, which is the base end. The clamping portion 3 has a groove portion 10 shaped according to the shape of the tip of the bulging portion 4.

[0070] The tip of the bulge 4 may be disposed so as to fit into the groove 10. With this configuration, when an object to be clamped is clamped by the clamping unit 3, the bulge 4 is pressed and bent by the object to be clamped, and the tip fits inside the groove 10. When the tip of the bulge 4 fits inside the groove 10, part or all of the tip is hidden inside the groove 10. This prevents the tip of the bulge 4 from getting caught on the surface of the bag 50 when the bag 50 is pulled out of the clamping tool 1. This prevents the bag 50 from being damaged.

[0071] Fig. 6 is a diagram showing an example of the configuration of the clamping tool 1 in the second embodiment. In the example shown in Fig. 6, the groove portion 10 is formed as a recess in the clamping portion 3 in plan view. The groove portion 10 has a shape corresponding to the shape of the tip of the bulge portion 4 in plan view.

[0072] In the second embodiment, the bulging portion 4 is formed in a claw shape that protrudes toward the opposing clamping portion 3. As an example, the bulging portion 4 may be configured in a plate shape that protrudes toward the opposing clamping portion 3. The groove portion 10 is formed by drilling the clamping portion 3 according to the shape of the tip of the bulging portion 4.

[0073] 6, the tip of the bulge 4 is disposed so as to enter the groove 10. Alternatively, the bulge 4 may be disposed outside the groove 10, and arranged so that when the bulge 4 is pressed by an object to be clamped and bent, the tip of the bulge 4 enters the groove 10. With this configuration, the bulge 4 can bend more greatly in the width direction.

[0074] Fig. 7 is a diagram showing an example of the configuration of groove portion 10 in the second embodiment. Fig. 7 is a partially enlarged view showing the shape of the periphery of groove portion 10. Groove portion 10 is formed by drilling into the inside of clamping portion 3. Bulging portion 4 is arranged so that its tip can enter groove portion 10. When an object to be clamped enters clamping portion 3, bulging portion 4 is pressed by the object to be clamped and bends toward clamping portion 3, which is the base end.

[0075] The bulge 4 bends, allowing the tip to enter the groove 10. The bulge 4 stops when the tip abuts against the inner surface of the groove 10. When the bulge 4 stops, the object to be clamped is pressed by the bulge 4 in the opposite direction to the surface that is in contact with the bulge 4.

[0076] Fig. 8 is a diagram showing an example of a groove portion 10 having a configuration different from that of the groove portion 10 shown in Fig. 7. In the example shown in Fig. 8, the opening of the groove portion 10 rises so as to conceal the tip of the bulging portion 4. The opening of the groove portion 10 may also rise so as to conceal the tip of the bulging portion 4 from the side closer to the base 2.

[0077] The opening of the groove 10 rises according to the shape of the bulging portion 4, concealing the tip of the bulging portion 4. In the example shown in FIG. 8 , the opening end of each groove 10 formed in the clamping portion 3 rises according to the shape of the bulging portion 4 at the side closer to the base 2, concealing the tip of the bulging portion 4. As an example, the distance between the opening end closer to the base end of the groove 10 and the center line L1 may be shorter than the distance between the tip of the bulging portion 4 and the center line L1. The thickness in the height direction of the bulge at the opening end may be configured to be approximately the same size as the thickness of the bulge 4. The bulge at the opening end may be formed so as not to abut against the tip of the bulging portion 4. The bulge at the opening end may rise from the side closer to the base 2 toward the tip of the clamping portion 3.

[0078] With this configuration, when the bag 50 is pulled out of the clip 1, the open end of the groove 10 near the base 2 comes into contact with the bag 50, making it difficult for the tip of the bulge 4 to come into contact with the bag 50. Therefore, with this configuration, it is possible to more preferably prevent the tip of the bulge 4 from getting caught on the surface of the bag 50.

[0079] (Third embodiment) Next, a third embodiment of the present invention will be described. In the third embodiment, the bulging portion 4 has a closed hollow between the raised edge and the clamping portion 3.

[0080] 9 is a diagram showing an example of the configuration of the clamping tool 1 in the third embodiment. Both ends of the bulging portion 4 are connected to the clamping portion 3, and the top portion rises toward the opposing clamping portion 3. The bulging portion 4 has a closed hollow between it and the clamping portion 3. This configuration makes it possible to prevent the tip of the bulging portion 4 from getting caught on the object to be clamped.

[0081] The bulging portion 4 may be formed integrally with the clamping portion 3, or may be separably connected thereto. The bulging portion 4 may be made of an elastic material such as rubber or resin. The bulging portion 4 may be configured in an arch shape in a plan view. With such a configuration, when the bulging portion 4 is pressed by an object to be clamped, the bulging portion 4 can effectively withstand the pressing force received from the object to be clamped. With such a configuration, it is possible to prevent damage such as breaking of the bulging portion 4 compared to when the tip of the bulging portion 4 is not connected to the clamping portion 3.

[0082] Unlike the example shown in Fig. 9, the bulging portion 4 may be configured with a protruding apex in a triangular shape in plan view. A closed hollow in a triangular shape in plan view may be provided between the raised edge of the bulging portion 4 and the clamping portion 3. With this configuration, the bulging portion 4 can better support the pressing force received from the clamped object than when configured in an arch shape in plan view.

[0083] Furthermore, unlike the example shown in Fig. 9, the bulging portions 4 may not be hollow. As an example, the bulging portions 4 may be raised in a lump-like shape. Opposing bulging portions 4 may be arranged asymmetrically with respect to the center line L1.

[0084] (Fourth embodiment) Next, a fourth embodiment of the present invention will be described. In the clip 1 illustrated in the fourth embodiment, the distance between the tops of opposing bulging portions 4 in the width direction increases toward the tip.

[0085] 10 is a diagram showing an example of the configuration of the clamping tool 1 in the fourth embodiment. The top of the bulging portion 4 is adjacent to the opposing clamping portion 3 across the center line L1. The opposing bulging portions 4 are arranged asymmetrically with respect to the center line L1.

[0086] In the example shown in Fig. 10, a plurality of bulging portions 4 are arranged in the longitudinal direction of the opposing clamping portions 3. The distance in the width direction between the apexes of a pair of bulging portions 4 may be configured to increase toward the tip of the clamping portion 3. As an example, the distance in the width direction between the apex and the base end of a bulging portion 4 may be configured to increase toward the tip. With this configuration, it is possible to prevent the clamping portion 3 from expanding in the width direction when the pair of bulging portions 4 formed on the tip side of the clamping tool 1 clamp an object to be clamped.

[0087] 10, the widthwise distance between the opposing clamping portions 3 may gradually decrease toward the tip. The clamping portions 3 may be configured so that their widths narrow toward the tip. The clamping portions 3 may gradually approach the center line L1 toward the tip in a planar view. In this case, the widthwise distance between the apex and the base end of the bulging portion 4 may be approximately the same from the base 2 side to the tip.

[0088] With this configuration, when an object to be clamped is clamped by the clamping portion 3, it is possible to prevent the opposing clamping tool 1 from being widened in the width direction by the object to be clamped. This makes it possible to prevent the object to be clamped from falling off the clamping tool 1.

[0089] Fig. 11 is a diagram showing an example of the configuration of the clamping tool 1 in the fourth embodiment. The clamping tool 1 shown in Fig. 11 may clamp, for example, the lower part of the opening 52 of the bag 50, which is the object to be clamped, from the lateral direction. With this configuration, it is possible to suitably close the opening 52.

[0090] 11, the clamping tool 1 may further include a lock 15 at the tip of the clamping portion 3. The lock 15 is a member that can connect the tips of opposing clamping portions 3. When the tips of the clamping portions 3 are connected by the lock 15, the pressing force of the bulging portion 4 against the clamped object increases.

[0091] Furthermore, when the tips of the clamping portions 3 are connected to each other by the lock 15, the openings of the clamping portions 3 are closed, so that it is possible to suitably prevent the object to be clamped from falling off.

[0092] (Variation) The present invention is not limited to the details described in the above embodiments. Applicable modifications are shown below.

[0093] In each of the above embodiments, the tip of the bulging portion 4 points toward the base portion 2, but this is not limited thereto, and the tip of the bulging portion 4 may be configured to point toward the tip of the clamping portion 3.

[0094] In each of the above embodiments, the clip 1 is provided with the reinforcing portion 6, but the present invention is not limited to this and the clip 1 may not be provided with the reinforcing portion 6.

[0095] In each of the above embodiments, the pair of bulging portions 4 have point-symmetric shapes, but this is not limiting, and the pair of bulging portions 4 may be configured to have different shapes.

[0096] The bulging portion 4 may be configured to bulge from one clamping portion 3 toward the opposing clamping portion 3. The bulging portion 4 may be configured in the shape of a lump bulging from the clamping portion 3.

[0097] In each of the above embodiments, the clamping tool 1 has been described as being capable of clamping an item having an opening, but this is not limited to this and it is capable of clamping any item, regardless of whether it has an opening or not.
