Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip used to hold various objects such as multiple sheets of paper and clothes after washing.

Clips are daily necessities that can hold various objects such as multiple sheets of paper, and there are various types depending on the application. It has a solid structure and is often used when bundling relatively thin objects such as several sheets of paper. In addition, eyeball clips and double clips are often used when bundling thicker objects such as dozens of sheets of paper. , the clamping part on the opposite side opens, and various objects can be clamped there. In addition, many clothespins have a structure that combines synthetic resin and metal because it is necessary to achieve both prevention of damage to clothes and securing of holding power. Concerning the technological development of such clips, the following patent documents can be cited as specific examples of clips mainly composed of a bar material such as a wire.

Patent Literature 1 discloses a clip that is easy to use and has versatility. This clip is formed by bending a single metal wire, and includes a pair of pinching pieces, an extension extending from each pinching piece, and a tightening portion positioned near the boundary between the pinching piece and the extension. Of which, the tightening portion is formed in an elongated ring shape, and the portion near the base end of the pinching piece passes through this tightening portion, and a pair of extension portions are formed by the tightening portion It has a shape in which the interval gradually widens as the distance from the point increases. By pinching the pair of extensions with fingers or the like, the pair of pinching pieces are opened with the tightening portion as a fulcrum, and various articles can be held therebetween.

Patent Literature 2 discloses a clip that is easy to operate and is designed to be easy to use. This clip is composed of two elements: one member formed by forming a bar such as a metal wire into a ring shape, and the other member formed by forming the bar into a U shape. A portion and a proximal portion are provided. Further, the other member has a bilaterally symmetrical ring portion that protrudes in a branch shape. By winding the ring portion around the one member, the one member and the other member are integrated in a displaceable state. Then, when the base ends of both the one member and the other member are pulled together with a finger or the like, the opposite clamping end portions are opened. The force for pressing the clamping ends together is generated by elastic deformation in the vicinity of the ring portion.

Since the eyeball clip and the double clip are composed of a plurality of parts, the time and labor involved in manufacturing them increases. When disposing of such clips, it is sometimes necessary to disassemble them in order to facilitate recycling. It may lead to trouble. Therefore, it is desirable to configure the entire clip as a single component, as in Patent Document 1 described above. However, in Patent Document 1, due to its structure, it is difficult to increase the force for closing the pair of clamping pieces, and it is also difficult to increase the opening of the pair of clamping pieces, which may limit the application.

The present invention was developed on the basis of such circumstances, and provides a clip that is integrally formed from a single material so that it can be used in a variety of applications, and in order to reduce labor during manufacturing and disposal. purpose.

The invention according to claim 1 for solving the above-mentioned problem is a clip made of a single rod material, which has a pair of clamping parts for clamping an object to be clamped, and the pair of clamping parts are connected via a fulcrum portion, and each of the holding portions is formed by bending the rod material by approximately 180 degrees, and a short shaft portion directed to the fulcrum portion is connected to one end side thereof. The other end is connected to a long shaft portion that passes through the vicinity of the fulcrum portion and extends beyond it, and the fulcrum portion is formed by bending the bar into a coil shape. Each of the short shaft portions is connected to the fulcrum portion, and a pair of the short shaft portions are arranged to face each other with the coil-shaped bent fulcrum portion therebetween. The pair of clamping portions can be closed by a reaction force generated by elastically deforming the fulcrum portions, and the pair of long shaft portions are arranged so as to sandwich the outer periphery of the fulcrum portions. When the distal end side of the long shaft portion of is brought closer, the long shaft portion comes into contact with the fulcrum portion to open the pair of holding portions.

The clip according to the present invention can be manufactured simply by deforming a single bar, and in this respect, it is the same as the conventional gem clip. However, in the present invention, it is desirable to use a bar that is thicker than the paper clip from the viewpoint of ensuring strength. As for the material of the bar, if the original function can be secured, metals such as iron and aluminum, as well as synthetic resin and wood can be freely selected. A single bar is given a name for each region according to its role, and specifically, it is divided into a clamping portion, a fulcrum portion, a short shaft portion and a long shaft portion.

The clamping parts are parts for clamping various objects to be clamped, and are inevitably arranged so that a pair of the clamping parts face each other, and the gap between them can be changed by manual operation. In addition, the bar is elastically deformed in advance so that the object to be clamped can be firmly clamped, and the reaction force of the elastic deformation enables the pair of clamping portions to be closed at all times. Further, the fulcrum portion plays a role of connecting a pair of holding portions, each holding portion is connected to the fulcrum portion, and the pair of holding portions always maintains a state of facing each other.

Each clamping portion is formed by bending a bar material approximately 180 degrees. Therefore, the clamping portion has two rows of rods, both of which extend toward the fulcrum portion. The short shaft is connected to the fulcrum. Therefore, the reaction force generated by the elastic deformation of the fulcrum is transmitted to the clamping section via the short shaft, and the pair of clamping sections can be closed. The long shaft portion, on the other hand, does not connect to the fulcrum portion, but passes through the vicinity of the fulcrum portion and extends beyond it.

The fulcrum has a role of connecting a pair of clamping portions, and each clamping portion is connected to the fulcrum via the short shaft portion as described above. Further, the fulcrum serves as a source of force for constantly closing the pair of clamping portions. Therefore, the fulcrum is formed by bending a bar into a coil shape, and like a normal coil spring, when twisted about its center, a reaction force is generated. This reaction force displaces the clamping portions via the short shaft portion, thereby closing the pair of clamping portions. The detailed form of the fulcrum portion is arbitrary, and the number of turns is not limited. In addition, instead of forming the fulcrum in a simple coil shape, it is also possible to form a shape in which the bar member is bent in the middle and has a cut in the circumferential surface extending in the coil shape.

Since the short shafts extend from each clamping portion, two short shafts reach the fulcrum. The two short shafts are arranged to face each other across the center of the coiled fulcrum, and each is connected to the fulcrum. Therefore, when the pair of holding portions are displaced in the direction to open them, the fulcrum portion is twisted, and the elastic deformation causes a reaction force to close the pair of holding portions.

The tip side of each long shaft portion extends to the opposite side of the clamping portion with respect to the fulcrum portion. In addition, the long shaft portion is arranged so as to be able to contact the outer periphery of the fulcrum portion. Moreover, the two long shaft portions are arranged to face each other across the center of the fulcrum portion bent like a coil, like the short shaft portions. Therefore, when the tip sides of the two long shafts are brought closer together, the long shafts come into contact with the fulcrum, and this contact point functions as the fulcrum of the long shafts. is displaced in the direction of moving away, the pair of clamping parts are inevitably opened, and an object to be clamped can be inserted between them. At that time, since the short shaft portion is also displaced together with the clamping portion, the fulcrum portion is twisted, and the object to be clamped can be clamped by the reaction force.

In this way, by forming the clip from a single bar, the entire clip can be utilized as a resource without requiring work such as disassembly when it is disposed of after its use. Further, the fulcrum portion can obtain a stable reaction force by bending a bar and forming it in a coil shape, and can strongly close the pair of holding portions. Further, since the pair of long shaft portions are arranged so as to sandwich the fulcrum portion, it is easy to widen the distance between them, a sufficient amount of displacement can be secured, and the pair of holding portions can be opened widely.

The invention according to claim 2 is intended to improve convenience, etc., and is characterized in that the cross-sectional shape of a portion of the bar is changed by pressing or cutting. Although the cross-sectional shape of the bar can be freely determined, it is usually circular in view of availability. Further, in the present invention, since the contact portion with the finger and the pinching portion are also composed only of the bar material, the bar material with a circular cross section reduces the contact area with the finger or the object to be pinched, and also tends to cause slippage. . Therefore, by changing the cross-sectional shape of the bar as in the present invention, it is possible to increase the contact area and friction with the finger or the object to be held, thereby improving the convenience. The pressing process causes plastic deformation of the bar material, and the cutting process includes cutting out grooves for anti-slipping.

In the third aspect of the invention, the relationship between the long shaft portion and the fulcrum portion is specified, and in order to prevent the long shaft portion from detaching from the fulcrum portion, a guide groove is formed at the contact point between the two. It is characterized by The long shaft portion extending from the holding portion is arranged so as to be in contact with the outer periphery of the fulcrum portion. will be displaced with the contact point as a fulcrum. At that time, if the long shaft portion slides down from the outer periphery of the fulcrum portion, the long shaft portion cannot perform its original function, and the pair of clamping portions cannot be opened.

Therefore, by forming a guide groove at the contact point between the long shaft portion and the fulcrum portion, either one of the long shaft portion and the fulcrum portion is fitted there, and the long shaft portion cannot be separated from the fulcrum portion. You can be sure that it will perform its intended function. The guide groove may be formed on either the long shaft portion or the fulcrum portion. In addition, it is desirable that the rod material constituting the clip has a certain thickness so that the guide groove can perform its original function.

As in the invention according to claim 1, the clip is composed of a single bar, and the bar is deformed to be divided into four regions consisting of a holding portion, a fulcrum portion, a short shaft portion, and a long shaft portion, In addition to sandwiching the object to be clamped between the pair of clamping parts, the fulcrum part is bent into a coil shape, and the clamping part and the fulcrum part are connected at the short shaft part. By arranging so as to sandwich the outer periphery of the long shaft portion, the distal end side of the long shaft portion can be operated to displace the sandwiching portion. In the present invention, the entire clip can be manufactured from only one bar, and when the clip is disposed of after the end of its use, work such as disassembly is unnecessary, and the entire clip can be utilized as a resource.

The fulcrum is made by bending a rod material into a coil, and like a normal coil spring, when twisted about its center, it can generate a stable reaction force due to elastic deformation. , the pair of clamping portions can be strongly closed. In addition, since the pair of long shafts are arranged so as to sandwich the outer periphery of the fulcrum, it is easy to widen the distance between them, and a sufficient amount of displacement can be ensured when the tip side of the long shafts is operated. , the pair of clamping portions can be opened wide. As a result, it can be used in various fields without being subject to restrictions on usage.

As in the second aspect of the invention, the cross-sectional shape of a portion of the bar is changed by pressing or cutting to form a planar portion or the like, so that the area of contact with a finger or an object to be clamped is reduced. can be increased. At the same time, by continuously forming fine grooves, etc., friction is increased, and slippage between fingers and objects to be held can be prevented, improving convenience.

As in the third aspect of the invention, in order to prevent the separation of the long shaft portion and the fulcrum portion, a guide groove is formed at the contact point between the two, so that when the leading end sides of the pair of long shaft portions are brought close to each other, Either one of the long shaft portion and the fulcrum portion is fitted in the guide groove to prevent the long shaft portion from slipping down from the outer circumference of the fulcrum portion. Therefore, the long shaft portion can reliably perform its original function, and malfunctions are not caused.

FIG. 2 is a perspective view showing an example of the shape of a clip according to the present invention. Below, the clip is depicted open. FIG. 2 is a perspective view showing the details of the clip of FIG. 1, and in the lower part of the drawing, an enlarged cross section of the contact point between the long shaft portion and the fulcrum portion is drawn. FIG. 2 is a perspective view showing a clip having a shape different from that of FIG. 1, in which the fulcrum portion is not in a simple coil shape, but in which the bar member is bent in the middle, and the peripheral surface extending in the coil shape has a cut. has the form.

FIG. 1 shows an example of the shape of the clip according to the present invention, the upper part of the figure shows the clip closed, and the middle part of the figure shows the clip divided at the fulcrum 21. , the bottom of the figure depicts the clip open. This clip is made by deforming a metal bar with a circular cross section, and does not use any other parts. The clip has a fulcrum portion 21 formed by bending a bar material into a coil shape, and is positioned at the center. The fulcrum portion 21 in this figure is constructed by winding a bar material in a coil shape for one and a half turns, but the number of turns is arbitrary.

A pair of clamping portions 13 and 33 are vertically overlapped, and an object to be clamped can be clamped therebetween. Each of the clamping portions 13 and 33 is formed by bending a bar into a U shape, and the bars are inevitably arranged in two rows, one of which reaches the fulcrum 21. The short shaft portions 14 and 34 are connected to each other, and the long shaft portions 12 and 32 extending beyond the fulcrum portion 21 are connected to the other end. The short shaft portion 14 extending from the upper holding portion 13 extends obliquely upward and connects above the fulcrum portion 21 at its tip. On the other hand, the short shaft portion 34 extending from the lower holding portion 33 extends obliquely downward and is connected to the lower portion of the fulcrum portion 21 at its tip. In addition, the clamping portions 13 and 33 are flattened by deforming the bar material so as to crush it in order to increase the contact area with the object to be clamped.

The long shaft portion 12 extending from the upper clamping portion 13 extends obliquely upward in the same manner as the adjacent short shaft portion 14, but eventually extends horizontally, passes through the fulcrum portion 21, and extends beyond it. Further, the distal end side of the long shaft portion 12 is deformed so as to be crushed, and a planar lever portion 11 is provided. Further, the long shaft portion 12 extending from the upper holding portion 13 is arranged so as to be adjacent to the upper portion of the coil-shaped fulcrum portion 21 . A guide groove 25 is formed by locally recessing the fulcrum portion 21 at the contact point between the long shaft portion 12 and the fulcrum portion 21. By fitting the long shaft portion 12 into the guide groove 25, This prevents the long shaft portion 12 from being detached from the fulcrum portion 21 .

The long shaft portion 32 extending from the lower holding portion 33 extends obliquely downward, then extends horizontally, passes through the fulcrum portion 21 and extends beyond it, and a lever portion 31 is formed on the tip side thereof. be. Further, the long shaft portion 32 is arranged so as to be adjacent to the lower portion of the fulcrum portion 21, and at the contact point between the long shaft portion 32 and the fulcrum portion 21, the fulcrum portion 21 is locally depressed. A groove 25 is formed to prevent the long shaft portion 32 from detaching from the fulcrum portion 21 . The pair of lever portions 11 and 31 is a portion that is manually operated when opening the pair of holding portions 13 and 33, and is finished in such a flat shape so as to relieve the pressure acting on fingers and the like. .

As depicted in the lower part of this figure, when the pair of levers 11 and 31 are pinched with fingers and brought closer together, the individual long shafts 12 and 32 are displaced with the point of contact with the fulcrum 21 as a fulcrum. A pair of clamping parts 13 and 33 are opened, and an object to be clamped can be inserted between them. When the pair of holding portions 13 and 33 are opened, the pair of short shaft portions 14 and 34 are also displaced, so that the fulcrum portion 21 is twisted. Therefore, when the operation of the lever portions 11 and 31 is released, the pair of clamping portions 13 and 33 are displaced in the closing direction due to the reaction force of the elastic deformation generated in the fulcrum portion 21, so that the clamped object can be clamped. In order to strengthen the pinching of the object to be pinched, it is desirable to twist the fulcrum portion 21 during the manufacturing stage of the clip so that a constant reaction force is generated.

FIG. 2 shows details of the clip of FIG. This clip is made up of only one rod member with a circular cross section, and the lever portions 11, 31 and clamping portions 13, 33 thereof also initially have a circular cross section as shown in this figure. However, these portions are flattened by pressing the bar during the manufacturing stage. In addition, a guide groove 25 is formed in the fulcrum portion 21 at the contact point between the long shaft portions 12, 32 and the fulcrum portion 21. The long shaft portions 12 and 32 are prevented from being detached from the fulcrum portion 21 by the fitting of the 32 . Note that the fulcrum portion 21 is formed by bending a rod into a coil shape as shown in this figure. Therefore, in this section, the rods are adjacent to each other, and a valley is inevitably formed at the boundary between the rods. It can also prevent detachment.

FIG. 3 shows a clip with a shape different from that of FIG. It has a form with cuts. In this way, the fulcrum part 21 is based on the premise that the bar is bent into a coil shape, but instead of the simple coil shape shown in FIG. It is also possible to provide a form having a cut. Even in this case, the right portion of the fulcrum portion 21 connects the upper and lower sides without interruption, and the pair of holding portions 13 and 33 are connected by the fulcrum portion 21 without change. A guide groove 25 is formed in the fulcrum portion 21 in the same manner as in FIG.

In the clip shown in this figure, the clamping portions 13 and 33 are formed in the shape of "Ω" to widen the width, so that a larger object to be clamped can be clamped. In addition, the surfaces of the pair of holding portions 13 and 33 that come into contact with the object to be held are knurled to prevent slippage. The lever portions 11 and 31 are not oval shaped as in FIG. 1, but simpler circular shapes, and the surfaces that come into contact with the fingers are also knurled to prevent slippage. Thus, the shapes of the lever portions 11 and 31 and the clamping portions 13 and 33 can be freely determined according to the application. In addition, although it is assumed that the fulcrum portion 21 is also bent in a coil shape, its form and size can be freely determined.
