DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip, and more particularly, to a clip which can reduce the operating force of an operating portion for opening a clipping portion of the clip, and when the clipping portion is opened. The present invention relates to a clip capable of maintaining an open position.

[0002]

2. Description of the Related Art As a known clip, for example, FIG.
6, a clip 100 called a double clip as shown in FIG. 17 is known. This clip 100
Is a one-sided back plate portion 101 for determining a binding width, and a pair of one-sided holding portions 10 connected to both ends of the back plate portion 101.
2, 102 and a pair of operating portions 10 made of a wire rod rotatably supported at the respective ends of the holding portions 102, 102.
3, 103.

[0003] The clip 100 includes a pair of holding portions 102 and 1.
The tip of 02 is provided with a spring property that always keeps the closed position, and this spring property allows a document or the like to be sandwiched. When the operation units 103 and 103 are operated in the directions indicated by arrows in FIG. 16, the operation units 103 and 103 are attached to the back plate 101 and the holding units 102 and 1.
The connecting position with 02 rotates as a fulcrum P, P in a direction approaching each other, thereby making it possible to forcibly open the holding portions 102, 102.

[0004]

However, in such a clip, since the operating portions 103, 103 are supported at the distal end positions of the holding portions 102, 102,
The distance between the fulcrum P, P position and the tip position of the operation units 103, 103, that is, the force point position becomes longer, and the operation units 103, 10
There is a disadvantage that the force applied to 3 must be increased. Therefore, in order to be able to withstand such a force, conventionally, the materials of the operation units 103 and 103 are made of metal, and there is an inconvenience that usable materials are limited.

Further, in the conventional clip 100, with the document being sandwiched, the operation units 103, 103 can be positioned on the surface of the document as shown by a two-dot chain line in FIGS. 16 and 17. In this case, The length of the operation units 103, 103 protruding from the holding units 102, 102 is approximately equal to the length of the operation units 103, 103. for that reason,
The protruding amount is too long, which causes a disadvantage that the turning operation of the document is easily hindered.

By the way, in the case of the above-mentioned clip, since the holding portions 102, 102 are provided with a spring property that can always be kept in the closed position, the operating portions 103, 103 are operated to open the holding portions 102, 102. Even if the operation unit 103, 1
As soon as the operating force on the locking part 102 is released, the holding parts 102, 1
02 will be closed. Therefore, when sandwiching the edge region of the document, it is necessary to continuously apply a force in a direction in which the operation units 103 and 103 approach each other. Therefore, it is necessary to operate the operation units 103 and 103 with the other hand while holding the document with one hand, and if the number of documents to be sandwiched is large enough to support the document with both hands. Can not be pinched,
As a result, an inconvenience that the edges of the sandwiched document become uneven is caused.

[0007]

SUMMARY OF THE INVENTION The object of the present invention has been devised in view of such inconvenience. The purpose of the present invention is to reduce the operating force applied to the operating section to reduce the use of materials for the operating section. An object of the present invention is to provide a clip capable of circumventing restrictions.

Another object of the present invention is to provide a clip which can maintain the open position of the holding portion even when the operating force on the operating portion is released, and can hold a document in this state. It is in.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is configured such that the two members are rotatably connected to each other,
The first and second clip forming bodies are provided so as to be able to apply a pinching force of a document or the like via a predetermined spring force, and each clip forming body rotates relative to the holding section and the holding section. And an operating unit that can be opened between the holding units by a rotation operation with the rear side of the holding unit as a fulcrum, wherein the operating unit rotates at a position rearward from the tip of the holding unit. And a support shaft supported in the side end surface of the holding portion, and a loop-shaped portion connected between outer ends of the support shafts. . According to this,
When rotating the operation unit in the direction to open the holding unit,
Since the force point of the operation unit, that is, the distance between the support position and the fulcrum position is shorter than that of the conventional structure, the operation force when the front-rear length of the operation unit is the same as that of the conventional type is reduced. Therefore, since the shearing force applied to the operation unit is also reduced, the degree of freedom in selecting the material of the operation unit can be increased. In addition, the amount of protrusion when the operation unit is positioned on the surface of the document with the document sandwiched therebetween is shorter than that of the related art, so that the trouble of turning the page of the document is reduced. Further, since the operation section is configured to be supported on the side end surface of the holding section, the width of the operation section can be increased, and operability is prevented from being impaired even when the clip is downsized.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the operating portion is provided in a region from the rear end side of the holding portion to about 2/3 position around the length of the holding portion in the front-rear direction. Good to take. By supporting the operation unit in such a region, the above-described effect can be more effectively achieved.

Further, the respective holding portions are connected to each other with their rear end side as a center of rotation, while the spring force is applied by a leaf spring member, and the leaf spring member is mounted between the holding portions. A pair of pressing portions for pressing each of the holding portions from the outside in the state to apply a force so that the distal end side of the holding portion is in the closing position, and when the holding portion is in the closing position, the pressing portion is located between the pressing portions. Is located closer to the holding portion than the rotation center, and when the operating portion is rotated to the rear of the holding portion and operated in a direction approaching each other, the straight line is closer to the operating portion than the rotation center. There is also adopted a configuration in which the holding portion is moved to the side to maintain each holding portion in the open position. According to such a configuration, when the operating portions are brought close to each other to open the respective holding portions, the pressing force of the leaf spring member does not act in the direction to close the holding portions, and the opening position is maintained. And the operating force applied to the operating unit can be released. Therefore, it is possible to insert the end region of the document between the holding portions by supporting the document with both hands after the edge of the document to be inserted is aligned.
After that, by applying an external force in a direction in which the holding portions approach each other, the holding portions are relatively rotated to the holding position, whereby a holding force can be applied to the document.

In this case, it is preferable that a straight line connecting the pressing portions when the holding portion is at the open position is provided so as to slightly move toward the operation portion with respect to the rotation center. With such a configuration, the external force required to return the holding portion, which has been set to the open position, to the closed position is small.

In the present specification, “left”, “front” or “front” of a clip means the left side of FIG. 1, and “right” and “back” mean the same unless otherwise specified. It means the right side of the figure. Also, “up” and “down” are similarly used with reference to FIG.

The operating portion 31 is rotatably provided at the position of the support shaft 39, and as shown in FIG. 4, an operating force is applied in the direction of the arrow with the position where the loop portion 40 contacts the fulcrum forming base 37 as a fulcrum P. The support shaft 39
Is used as a force point to apply a force in a direction to open the holding portion 30.

The leaf spring member 15 is mounted on the fulcrum forming base 2.
A base piece 42 extending between the rear ends of the base pieces 2 and 37;
2 and a pair of bent pieces 43, 43 extending to the outer surfaces of the holding portions 16, 30, respectively. The leaf spring member 15 has an outer shape whose side end shape is substantially U-shaped. Bending piece 43, 43
Are formed in a substantially L-shape when viewed from the side, and the corners of the L-shape are formed as pressing portions 43A, 43A. These pressing portions 43A, 43A are provided in such a shape that they fit almost exactly in the bent notches 21, 36 described above. Here, when the leaf spring member 15 is removed, a length slightly shorter than the separated position of the pressing portions 43A, 43A shown in FIG. 1 is set as an initial separated position. That is, when the leaf spring member 15 is mounted between the first and second clip forming bodies 11 and 13, each of the pressing portions 43A and 43A is deformed in a direction away from the initial separation position. , Clamping part 1
The elasticity for closing the clips 6 and 30 is applied to the clip forming bodies 11 and 13 respectively.

When the leaf spring member 15 is in the state shown in FIG. 6, that is, when the holding portions 16 and 30 are in the closed position, a straight line L connecting the pressing portions 43A and 43A is formed.
Are located forward with respect to the rotation center C of the rotation shaft portion 18, and when the operation portions 17, 31 are rotated in the direction of the arrow in FIG. 6, as shown in FIG. 8, the pressing portions 43A, 43A
A straight line L connecting between them is provided so as to move behind the rotation center C, so that the holding portions 16 and 30 can be maintained at the open position.

Next, the clip 1 according to the first embodiment will be described.
The method of assembling and using 0 will be described. Here, the operation units 17, 31 correspond to the corresponding holding units 16, 30.
Assume that it is mounted in advance.

When assembling the clip forming bodies 11 and 13, the rotating shaft 18 on the first clip forming body 11 side is used.
And the bearing recess 33 on the second clip forming body 13 side are fitted to each other. Then, the leaf spring member 15 is attached so as to straddle between the rear ends of the holding portions 16 and 30. At the time of this mounting, the bending piece portions 43, 43 slightly expand and operate, and the pressing portions 43 at the positions of the bending notches 21, 36 of the holding portions 16, 30.
A and 43A are fitted, whereby the assembly of the clip forming bodies 11 and 13 is completed.

When the clip 10 is used, the operation units 17 and 31 are rotated in a direction away from each other from the state shown in FIG. Then, when each of the operation units 17 and 31 rotates to the position shown in FIG. 4, a part of the loop-shaped portions 25 and 40 comes into contact with the fulcrum forming stands 22 and 37, respectively. Here, by applying a further rotational force, the principle of leverage works with the contact points as fulcrums P, P, and the holding parts 16, 30 are set with the support shafts 24, 39 of the operation parts 17, 31 as the power points. It will be released. At this time, when the holding portions 16 and 30 are opened, the straight line L (see FIG. 8) connecting between the pressing portions 43A and 43A of the leaf spring member 15 becomes the center point C of the rotating shaft portion 18.
Than the pressing portions 43A,
The force of the 43A to return to the initial position, that is, the force of approaching each other, does not act as a closing force of the sandwiching portions 16 and 30, and thus maintains the open position.

With the holding portions 16 and 30 thus opened, a document is inserted between them, and the holding portions 16 and 30 are inserted.
By applying an external force to bring the 30 closer, the straight line L moves and closes the holding portions 16 and 30, thereby completing the sandwiching of the document.

In this state, the operation units 17 and 31 are
, The operation units 17 and 31 can be positioned in the plane of the document.

Therefore, according to such an embodiment, when operating the operating sections 17 and 31, the force points are held by the holding sections 16 and 3.
Since the distance between the force point and the fulcrum P is shorter than when provided at the leading end of the zero, the operating force applied to the free ends of the operating units 17 and 31 can be reduced. Therefore, the operation unit 1
It is possible to reduce the shearing force applied to the wires 7 and 31 as compared with the conventional case, whereby it is possible to use a material other than the metal wire, for example, a resin material.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the following description, the same reference numerals are used for portions that are substantially the same as those in the first embodiment, and the description is omitted or simplified.

In the second embodiment, the support position of the operation units 17 and 31 is set to the rear position close to the fulcrums P and P, and the operation units 17 and 31 follow the outer shape of the holding units 16 and 30. The feature is that it is provided in a shape to make the whole shape compact.

That is, the positions of the support shafts 24 and 39, which are the centers of rotation of the operation units 17 and 31, are set to positions immediately before the fulcrums 22 and 37 located at the rear of the holding units 16 and 30. Have been. The operation units 17 and 31
As shown in FIG. 9 and FIG.
When it falls down to the 0 side, it is formed in the loop-shaped parts 25 and 40 located along the outer periphery of the holding parts 16 and 30, whereby the operating parts 17 and 31 are placed on the surface of the document with the document held therebetween. , The page turning operation is hardly affected.

In the second embodiment, the holding portions 16, 30
Is in the closed position, as shown in FIG. 11, a straight line L connecting the pressing portions 43A, 43A of the leaf spring member 15 is formed.
However, the pinching force is maintained by being located forward of the center C of the rotating shaft portion 18. In this state, the contact position between the bases of the loop-shaped parts 25, 40 of the operation parts 17, 31 and the fulcrum forming bases 22, 37 becomes the fulcrum P, and the external force in the direction of the arrow causing the operation parts 17, 31 to approach each other. , The holding portion 16,
30 can be opened. The holding parts 16, 30
The leaf spring member 15 moves rearward from the initial position due to the angle change associated with the opening of, and moves slightly rearward from the center C (see FIG. 14).
The open positions of the holding portions 16 and 30 are maintained. Other configurations are substantially the same as those of the first embodiment.

Therefore, according to the second embodiment, since the support positions of the operation units 17 and 31, that is, the positions of the rotation center and the fulcrum P are very close to each other,
The principle of leverage can be demonstrated more strongly,
6, 30 opening force can be greatly reduced, and the operating units 17, 31
The degree of freedom in selecting the molding material can be further expanded.

In addition, the operating units 17 and 31 are
Since it is provided in a shape conforming to the outer shape of 30, the overall size can be made compact, the product package can be made small, and the handling in the distribution stage is advantageous.

[0036]

As described above, according to the present invention,
Since the operating unit is rotatably supported at a position behind the tip of the holding unit in the side end surface of the holding unit, the distance between the fulcrum and the fulcrum of the operating unit when rotating the operating unit is conventional. It is shorter than the structure, and it is possible to reduce the operation force when the length of the operation unit in the front-rear direction is the same as that of the conventional type. Therefore, since the shearing force applied to the operation unit is also reduced, the degree of freedom in selecting the material of the operation unit can be increased. In addition, the amount of protrusion when the operation unit is positioned in the plane of the document with the document sandwiched therebetween is shorter than that of the related art, so that the effect is obtained that the page of the document is easily turned. In addition, the width of the operation unit in the direction orthogonal to the front-rear direction can be increased, so that the operability of the operation unit can be favorably maintained particularly when the clip is downsized.

In the configuration in which the operating portion is provided in a region from the rear end side of the holding portion to about 2/3 position with respect to the length of the holding portion in the front-rear direction, the above-described effect can be better achieved. It becomes possible.

Further, a leaf spring member is used as a spring for keeping each of the holding portions at the closing position, and a pair of pressing portions for applying a force so that the distal end side of the holding portion is at the closing position is provided on the leaf spring member. When the holding portion is in the closed position,
While the straight line connecting the pressing portions is located closer to the holding portion than the center of relative rotation of the holding portion, when the operating portion is rotated and operated in a direction approaching each other, the straight line is operated more than the rotation center. Since it is configured to move to the unit side, when each of the holding portions is opened, the pressing force of the leaf spring member does not act in the direction to close these holding portions, and acts to maintain the open position, This makes it possible to release the operation force on the operation unit. Therefore, it is possible to insert the end region of the document between the holding portions by supporting the document with both hands after the edge of the document to be inserted is aligned.

In addition, since the straight line connecting the pressing portions when the holding portion is at the open position moves only slightly to the operation portion side from the center of rotation, the holding portion at the open position is not moved. The effect that the external force when returning to the closed position is small is sufficient.
