Description

  The present invention relates to a double clip for binding documents and the like.

  As shown in FIG. 4, the double clip is made of metal or plastic and has a scissor opening that is a part that sandwiches paper sheets, and a pair of opposing opening and closing that opens the scissor opening according to the “principle principle”. And a lever.

  The cross section of the double clip body has a triangular shape. The scissors opening is provided on the side corresponding to the apex, and the scissors opening is always closed by the elasticity of the portion corresponding to the base of the triangle unless an external force is applied.

  On the other hand, as described above, the double clip has a triangular cross section, and the pair of opening / closing levers are attached in a state of being rotatably supported on the scissor opening side. For this reason, the pair of opening / closing levers are arranged along the other two sides except the bottom side of the triangle when the pair of opening / closing levers are rotated around the scissor opening side and rotated toward the bottom side. It becomes like this. When the open / close lever is in this state, the open / close lever is in an open state.

  On the other hand, when the pair of opening / closing levers are rotated in the opposite direction and rotated until they contact each other, the opening / closing lever is in a closed state.

  By the way, the length dimension of the opening / closing lever is longer than the dimension of the double clip main body in which the paper sheets are sandwiched (the depth direction of the double clip).

  For this reason, when the open / close lever is in an open state, the pair of open / close levers are free ends on the side opposite to the scissor opening (hereinafter, the back side of the double clip) along the other two sides except the bottom of the triangle. The portion is positioned so as to extend rearward from the base.

  That is, the pair of opening / closing levers has a divergent form in accordance with the triangular cross-sectional shape of the double clip when the double clip body is viewed from the side. Therefore, in this state, the open / close lever protrudes rearward from the double clip body as it goes to the free end side, and the interval between the free ends increases.

Also, in order to sandwich the paper sheet with a double clip, the user pinches the open / close lever with the thumb and forefinger and applies force to both fingers so that the free ends of the open / close lever come close to each other . Then, according to the lever principle, the free end portion of each of the pair of opening / closing levers becomes a force point, the portion located on the scissor opening side becomes the action point, and the portion located between both portions and abutting against the double clip body Is the fulcrum. Then, when an external force that approaches the other end acts on each free end portion that becomes the force point, the portions attached to the scissor opening side with the fulcrum as a support move in a direction away from each other. To do. As a result, the portion corresponding to the bottom side of the double clip body is elastic, and a force acts in the direction of closing the scissor opening, so that the paper sheets placed in the scissor opening can be sandwiched.

Problems to be solved by the invention

  By the way, especially when using an oversized double clip, the distance between the free ends of the pair of opening / closing levers is too large for a person with a small hand, and it is difficult to use force.

  In addition, when the open / close lever is in an open state, the open / close lever extends in a divergent shape. Therefore, when the paper sheet is turned with the double clip closed, the turned paper sheet opens and closes. The turned paper sheets are raised at the contact portion when they hit the free end portion of the lever. For this reason, the turned paper sheet has an elastic force, and it may return to the state before being turned by a slight momentum.

  Therefore, the present invention makes it easy to open the scissors opening of the double clip, and when the paper sheet sandwiched between the double clips is turned, the double clip can be made difficult to rise at the position where the opening / closing lever and the paper sheet hit each other. The issue is to provide.

  The double clip of the present invention has been invented in view of the above circumstances. That is, a double clip body having a double clip body having a scissor opening for sandwiching paper sheets and a pair of opening / closing levers that open the scissor opening on the basis of this principle, wherein the double clip body includes the pair of opening / closing levers. A groove or a recess is formed at a contact point that becomes a fulcrum when used as a lever, and the pair of opening and closing levers are respectively housed in the groove or recess, and the opening and closing levers are mutually connected at the contact point. It is bent toward the direction approaching the other.

  By doing in this way, as for a pair of opening-and-closing lever, the space | interval of the free end becomes small compared with the conventional double clip. Therefore, even a child or a woman with a small hand can easily put a finger on the pair of opening / closing levers, and can easily apply force. For this reason, a double clip can be opened easily.

  Further, in the state where the pair of opening / closing levers are housed in the groove or the recess, the portion from the place in the groove or the recess to the point beyond that is the same height as the height of the double clip body. And you may make it bend in the direction which the part until the said cross | intersects mutually with respect to the other so that it may become parallel. In this way, when the paper sheet is turned in a state where the paper sheet is sandwiched between the double clips and the pair of opening / closing levers are open, the opening / closing lever and the paper sheet are in contact with each other. The swell can be made larger than the height of the double clip body.

  In this way, the rise of the paper sheets that can be generated when the paper sheets are turned in a state where the paper sheets are sandwiched by the double clip can be suppressed, so the elasticity generated when the paper sheets are turned There is no return to the state before the paper was turned over. Therefore, the state in which the paper sheets are turned can be stably maintained.

  Paper clips can be easily sandwiched with a double clip. In addition, when turning the paper that is sandwiched between the double clips, it is possible to prevent swell at the location where the open / close lever and the paper hit, so that the state where the paper is turned can be stably maintained. it can.

  As can be seen from FIGS. 1 to 3, the double clip 1 includes a double clip body 2 having a scissor opening 2 m that sandwiches a paper sheet 4, and a pair of opening / closing levers 3 that open the scissor opening 2 m according to this principle. .

  When the clip main body 2 is used in a state where the pair of opening / closing levers 3 are opened, a groove 21 is formed at a contact portion serving as a fulcrum. The pair of opening / closing levers 3 are partially accommodated in the grooves 21, and the opening / closing levers 3 are bent in a direction approaching each other at the contact portion.

  Specifically, the pair of opening / closing levers 3 are arranged so that the portion ahead of the groove 21 is parallel to the height of the double clip main body 2 and is parallel to each other, or the portion up to the tip is mutually on the other side. It is bent in the direction that intersects the extension line

  Therefore, according to the double clip 1, even when the pair of opening / closing levers 3 is in an open state, the distance between the opening / closing levers on the free end side is smaller than that of the conventional double clip, so that the hand is small. A person, for example, a child or a woman, can easily put a finger on the pair of opening / closing levers 3. Accordingly, it is possible to easily apply a force to the opening / closing lever of the double clip 1, so that the scissor opening 2m of the double clip 1 can be easily opened / closed.

  Further, when the pair of opening / closing levers 3 are housed in the grooves 21, the portions ahead of the grooves 21 are parallel to each other at the same height as the height of the double clip body 2, or cross each other. The double clip body is raised at the point where the open / close lever 3 and the paper sheet 4 hit when the paper sheet 4 is turned with the paper clip 4 sandwiched between the double clip 1 It can suppress becoming more than 2 height dimensions. As a result, the turned state of the paper sheets 4 can be stably maintained.

  Moreover, in the part used as the bottom face of the double clip 1, since one side of an opening-and-closing lever is settled in the groove | channel 21 at the bottom face side, a bottom face becomes planar. For this reason, when the paper sheet 4 is sandwiched between the double clips 1 and placed on a desk, for example, the paper sheet 4 can be kept stable.

In addition, said embodiment is only an Example and is not limited to the content of a specification.
Further, a recess may be used instead of the groove 21.

  It is a whole perspective view of the double clip concerning the present invention.   FIG. 3 is a side view of FIG. 2.   It is a whole perspective view which shows the state which has bound the paper sheets using the double clip which concerns on this invention.   It is a side view of the conventional double clip.
