Description

[Detailed description of the invention] (Industrial application field) The present invention is a versatile clip that can be used like clothespins, pants hangers, clips used in laundry shops, and other clips. Regarding clamps.

(Prior Art) Conventionally, as this type of clamping tool, there is a clip hanger as shown in, for example, Japanese Utility Model Publication No. 56-7234. This is made by forming the clip body by connecting the base ends of arms with clamping pieces at the tips on both the left and right sides of the base to which the hook is attached, and the clip itself is a separate elliptical shape. By using a ring body to surround the pair of arms in an external manner, the gripping state of the clip main body by the gripping pieces can be maintained.

However, with the above-mentioned clip hanger, the object to be held is held between the holding pieces of the clip body and then the oblong ring body is attached to the arm, so it is very troublesome to attach and remove the object, and it is difficult to obtain the holding state easily. However, since opening and closing are performed by attaching and removing the oblong ring body, strong clamping force cannot be exerted.

In order to resolve these difficulties,
A clamping tool as described in Japanese Utility Model Publication No. 59-192399, a clip hanger as described in Japanese Utility Model Application No. 63-175600, and a clip hanger as described in Japanese Utility Model Application Publication No. 63-158300. clip hanger,
Hangers such as those described in Japanese Utility Model Application No. 64-11200 and clamping tools such as those described in Japanese Utility Model Application Publication No. 62-112592 have been invented and devised.

(Problem to be solved by the invention) However, with the above-mentioned clamping tools, clip hangers, hangers, etc., the clamping part cannot be opened relatively wide, and it is difficult to clamp relatively thick objects. There are drawbacks in which it is not possible, and even if the gripping portion can be opened relatively wide, there are drawbacks in that a considerable amount of hand and finger force is required when applying force to close the gripping portion from the wide open state. Furthermore, even if it is possible to easily apply force to close the clamping part, there are disadvantages in that the part that slides into contact to close the clamping part is fixed, and that part is subject to severe wear and damage and lacks durability.

(Means for Solving the Problems) Therefore, the present invention solves the above-mentioned difficulties, makes it possible to obtain a secure clamping state with a small amount of force, and also makes it possible to maintain this clamping state reliably. , Moreover, the configuration of the clamping tool itself is simple,
It was devised to provide a clamping tool that is highly durable and more convenient to use.

The clamping tool is integrally formed with a suitable synthetic resin material. Then, the connecting piece 5 and the other clamping piece 3
The other end portion of the connecting piece 5 that is connected to the holding piece 5 is formed into a flexible hinge shape and serves as a swinging fulcrum 5a for the pair of clamping pieces 2 and 3. Then, the other clamping piece 3
A substantially flat pressed surface 3b is located near the proximal end of the
The operating tension part 11 is provided with a protruding curved pressing surface 11c whose distance from the hinge part 12 gradually increases as it goes toward the tip, and which can slide into contact with the pressed surface 3b. As the operating tension part 11 swings in a predetermined direction using the hinge part 12 as a fulcrum, the curved pressing surface 11c of the operating tension part 11 gradually slides into contact with the pressed surface 3b of the other clamping piece 3. Pressure,
The other clamping piece 3 is configured to swing around the swinging fulcrum 5a, and the interval between the clamping parts 4 is gradually narrowed. Furthermore, an engaging portion 2a provided continuously on the end of the pressed surface 3b closer to the connecting piece 5, and an engaging portion 2a provided on one of the clamping pieces 2, are connected to the proximal end portion of the actuating tension portion 11. Engagement portions 11a and 11b provided at the tip portions respectively
A means is adopted in which the gripping portions 4 of the gripping body 1 are closed while being removably engaged with each other.

(Function) Thus, in the clamping body 1, the pair of clamping pieces 2 and 3 swing about the swinging fulcrum 5a of the connecting piece 5, and the clamping part 4 at the tip portion opens and closes widely. Moreover, the actuating tension part 11 of the actuating body 10 swings about the hinge part 12 as a fulcrum, so that the pair of clamping pieces 2 and 3
The proximal end portion of the gripping portion 4 is moved out of the space, and the gripping portion 4 is opened more widely. Further, the actuating tension portion 11 can be placed within the base end partial space of the pair of clamping pieces 2 and 3 by swinging in a predetermined direction about the hinge portion 12 as a fulcrum. Further, the curved pressing surface 11c of the actuating tension portion 11 gradually presses the pressed surface 3b while slidingly contacting the pressed surface 3b of the other clamping piece 3, and at this time, the curved pressing surface 11c and the pressed surface 3

In the case of the pressed surface 3b, the proximal end moves gradually toward the distal end. And the other clamping piece 3
The engaging portions 11a and 11b of the actuating tension portion 11 are removably engaged with the engaging portion 3a of the lever 2 and the engaging portion 2a of one of the clamping pieces 2. , this state is maintained as the clamping portion 4 is closed.

(Example) Hereinafter, the present invention will be explained based on illustrated examples.

In the clamping tool of the present invention, a pair of clamping pieces 2 and 3 whose tip portions serve as a clamping part 4 are made to face each other at an appropriate interval, and a connecting piece 5 is horizontally suspended near the base ends of the pair of clamping pieces 2 and 3. A clamping body 1 is connected to the base end of one clamping piece 2 and is connected to the proximal end of one clamping piece 2 via a flexible hinge part 12, and the hinge part 12 is used as a fulcrum. The actuating body is formed by connecting a substantially hook-shaped operating part 13 to an actuating tension part 11 that can be placed in the proximal end space of the pair of clamping pieces 2 and 3 when swinging in a predetermined direction. 10 are integrally molded from, for example, polypropylene, Diuracon, or other appropriate synthetic resin material.

In the clamping body 1, the other end portion of the connecting piece 5, which is a continuous portion between the connecting piece 5 and the other clamping piece 3, is formed into a flexible hinge shape, and the pair of flexible pieces 2, 3 are formed in a flexible hinge shape.
The pair of clamping pieces 2 and 3 are formed to swing around the swing fulcrum 5a. That is, in the illustrated example, the connecting piece 5 is formed into a substantially wedge-shaped piece whose thickness gradually decreases from the end on one side of the holding piece 2 to the end on the other side of the holding piece 3. serves as a swinging fulcrum 5a that bends elastically.

Furthermore, a substantially flat pressed surface 3b is provided at the proximal end of the other clamping piece 3 of the clamping tool, and an end portion of this pressed surface 3b closer to the connecting piece 5 is provided. is provided with a substantially notch-shaped engagement portion 3a,
A substantially flat engaging portion 2a is provided at the base end portion of one of the clamping pieces 2.

In addition, the actuation tension part 11 of the actuating body 10 has a curved pressing surface 11c that is protruded from the hinge part 12 and has a curved pressing surface 11c that can slide into contact with the pressed surface 3b. It has been set up. That is,
As the operating tension section 11 swings in a predetermined direction with the hinge section 12 as a fulcrum, the curved pressing surface 11c of the operating extension section 11 moves against the pressed surface 3 of the other clamping piece 3.
b is gradually compressed while sliding in contact with each other, and the other clamping piece 3 swings about the swinging fulcrum 5a, so that the interval between the clamping parts 4 gradually narrows and quickly narrows.

Furthermore, due to the further rocking of the actuating strut 11, the engaging portions 11a and 11b provided at the proximal end portion and the distal end portion of the actuating strut portion 11, respectively, are moved from the engaging portion 3a provided on the other clamping piece 3. and an engaging portion 2a provided on one of the clamping pieces 2 in a removable manner, respectively.
The clamping portion 4 of the clamping body 1 is formed to be closed.
That is, when a force is applied in the direction in which the clamping part 4 of the clamping body 1 is opened (when a force is applied in the direction in which the base end portions of the clamping pieces 2 and 3 are closed), the actuating tension part 11 is moved toward the base of the clamping pieces 2 and 3. The clamping portion 4 receives pressure from the end portion.
is configured to prevent it from opening.

By the way, the pair of clamping pieces 2 and 3 of the clamping body 1

Then, the curved pressing surface 11c of the operating tension part 11 slides and gradually presses the pressed surface 3b of the other clamping piece 3, so that the clamping part 4 is forcibly closed. Then, the actuating body 10 is further swung, and the engaging portion 11b at the tip of the actuating thrust portion 11 (curved pressing surface 11c) is connected to the engaging portion continuous to the pressed surface 3b of the other clamping piece 3. 3a, the engaging portion 2a provided on one of the clamping pieces 2 and the engaging portion 11a provided on the base end portion of the actuating tension portion 11 engage, and,
The clamping part 4 of the clamping body 1 is closed, and the object to be clamped is properly clamped by the clamping part 4. Moreover, in order to release the clamped state of the object to be clamped, the engaging part 11b at the tip of the actuating tension part 11 and the engaging part 3a of the other clamping piece 3

All you have to do is swing 0.

(Effects of the invention) Therefore, the clamping tool of the present invention is easy to use and can easily exert a strong clamping force based on the lever principle, and the clamping tool itself has a simple configuration. In addition to being able to have a small, lightweight, and compact structure, integral molding also improves mass productivity and allows for inexpensive provision.

In particular, the pair of clamping pieces 2 and 3 are arranged at appropriate intervals, the connecting piece 5 is arranged near the proximal end of the clamping pieces 2 and 3, and the connecting piece 5 and the other clamping piece 3 are connected together. The other end portion of the connecting piece 5 is formed into a flexible hinge shape to serve as a swinging fulcrum 5 for the pair of clamping pieces 2 and 3.
a, the clamping portion 4 of the clamping body 1 can be opened wide, and the clamping body 1 can be opened and closed smoothly, making it possible to easily clamp even relatively thick objects. Moreover, the actuating tension part 11 is connected to the base end of one of the clamping pieces 3 via the flexible hinge part 12, and the actuation tension part 11 swings in a predetermined direction with the hinge part 12 as a fulcrum. Since it is formed so that it can be placed in the proximal partial space of the pair of clamping pieces 2 and 3 during operation, when opening the clamping part 4,
The actuating body 10 can be kept swinging so that the actuating projection part 11 does not exist in the base end partial space of the pair of clamping pieces 2 and 3, and the clamping part 4 can be opened more widely.

In addition, a substantially flat pressed surface 3b is provided at the proximal end of the other clamping piece 3, and the operating tension portion 1
1 is provided with a curved pressing surface 11c that protrudes from the hinge portion 12 so that the distance from the hinge portion 12 gradually increases as it goes toward the tip, and that is capable of slidingly contacting the pressed surface 3b, and uses the hinge portion 12 as a fulcrum. As the operating strut 11 swings in a predetermined direction, the curved pressing surface 11c of the operating strut 11 gradually presses the pressed surface 3b of the other clamping piece 3 while sliding against it, and the other clamping piece 3 is pressed against the pressed surface 3b. 3 swings around the swing fulcrum 5d, and the interval between the clamping parts 4 is gradually narrowed, so that when applying force to close the clamping parts 4 from a wide open state, Just by swinging in the specified direction,
By gradually increasing the clamping pressure at the clamping part 4, even relatively thick objects can be completely clamped.
It does not require strong hand and finger strength and can be easily operated even by a person with limited physical strength, making it an easy-to-use clamping tool. In addition, the portions that slide into contact to close the clamping portion 4 (the sliding portion of the pressed surface 3b and the sliding portion of the curved pressing surface 11c) gradually change, and a smooth sliding state is obtained. This will prevent intensive wear and damage and improve durability.

Furthermore, the curved pressing surface 11c of the actuating tension portion 11
is formed so that the distance from the hinge part 12 gradually increases as the tip goes to the side, so when the clamping part 4 is gradually closed from the wide open state, the operating tension part 11 is The more it swings, the more the clamping part 4 closes relative to the unit swinging amount of the operating tension part 11, and the clamping part 4 can be closed more quickly.

Then, the proximal end portion of the actuating tension portion 11 is connected to the engaging portion 3a provided continuously on the end of the pressed surface 3b closer to the connecting piece 5, and the engaging portion 2a provided on one of the clamping pieces 2. Engagement portions 11a and 11b provided at the tip portions respectively
Since the structure is configured such that the clamping parts 4 of the clamping body 1 are closed while the clamping parts 4 are detachably engaged with each other, when the clamping parts 4 are in the clamping state, the pair of clamping pieces 2 and 3 are opened when the clamping parts 4 are about to open. The operating tension portion 11 can reliably prevent the proximal end portion from closing, and the clamping state of the clamping portion 4 can be easily and reliably maintained. Furthermore, the load on the hinge portion 12 can be reduced, and the durability of the clamping tool as a whole can be improved.
