Description

  The present invention relates to a punching tool for suitably forming a binding hole in a paper sheet.

  Conventionally, various punching tools for providing a binding hole for binding paper sheets have been proposed. These have a male blade and a female blade, and are provided with a support mechanism for supporting one of them movably. In many cases, paper sheets can be suitably perforated by accurately fitting the male blade and the female blade through the connection mechanism. And most of the drilling tools having such a configuration are provided with a special repulsion mechanism using an elastic member or the like, and after drilling with the male blade and female blade approaching at the time of drilling, the position before drilling The male blade and the female blade can be separated from each other.

On the other hand, there has been proposed a punching tool provided in a place where space is restricted, for example, a cover of a file by having a simple configuration (for example, see Patent Document 1). This can be reduced in size or thickness by simplifying the connection mechanism described above or omitting the repulsion mechanism, thereby greatly simplifying the configuration of the drilling tool itself. With a small number of sheets, a binding hole can be easily provided on the spot when it is necessary to bind the sheets.
JP 2005-349518 A

  However, in the case of the drilling tool as described above, the above-described repulsion mechanism that separates the male blade and the female blade during drilling is omitted, so that after drilling, the user separates the male blade from the female blade. It is necessary to newly work. Here, the punching device having such a simplified configuration is required to be capable of punching paper sheets more easily.

  Accordingly, the present invention has been focused on the above points, and provides a punching tool that can easily punch a paper sheet even in a punching tool having a simplified configuration, and a file including the punching tool.

  In order to achieve such an object, the present invention takes the following measures. That is, the punching tool according to the present invention passes through the punching protrusion with the punching protrusion protruding in the thickness direction of the paper sheet to be punched and the paper sheet sandwiched between the punching protrusion. Perforating recesses that can be accommodated to form a binding hole in the paper sheet, and a repulsive force in a direction that separates the perforation protrusions from the perforation recesses when the perforation recess accommodates the perforation protrusions It has at least an elastic support part constituted by a single sheet which supports the perforated convex part and the perforated concave part in a state where the perforated convex part is accumulated.

  If it is such, the perforation convex part and perforation recessed part at the time of perforating a paper sheet were suitably separated by the elastic repulsion force which the elastic support part constituted by a single sheet has accumulated. Therefore, the paper sheet can be removed from the perforation recess or the perforation recess without providing a special repulsion mechanism. By doing so, it is possible to provide a punching tool that can easily punch paper sheets while having a simple configuration.

  In order to realize accurate relative movement as a configuration in which the sheet is folded preferentially at the position of the elastic folding end, the elastic support portion has accumulated a repulsive force in the direction separating the perforated convex portion and the perforated concave portion. It is desirable to have a convex portion supporting portion and a concave portion supporting portion that support the perforated convex portion and the perforated concave portion so as to be movable relative to each other by the elastic repulsion force of the elastic folding end at which the sheet is folded.

  In order for the convex portion support portion and the concave portion support portion to be able to perform a more accurate relative movement, it is preferable to provide an elastic folding end between the convex portion support portion and the concave portion support portion.

  On the other hand, as another aspect of the elastic folded end, the sheet further includes an extending portion that extends from one or both of the convex portion supporting portion and the concave portion supporting portion, and the elastic folded end is supported by the convex portion supporting portion or the concave portion supporting portion. It can be mentioned that it is further provided between the part and the extension part. With such a configuration, the degree of freedom in design related to the position where the elastic folding end is provided can be improved.

  And in order to implement | achieve exact punching operation by positioning paper sheets suitably, an extending part shall be extended from any one of a convex part support part and a concave part support part, and a convex part support part In addition, it is desirable to have a pressing end that can always press the other in the operating range of the concave portion supporting portion.

  In the case of such a configuration, it is possible to stably position the paper sheet by providing the extending portion extending from the convex portion supporting portion and pressing the pressing end near the perforated concave portion in the concave portion supporting portion. Become.

  In particular, in order to position a paper sheet that is easy to perforate, it is preferable that the pressing end can press the vicinity of the perforation recess.

  In order to suitably hold the perforated convex portion or the perforated concave portion, at least one of the convex portion supporting portion and the concave portion supporting portion is held in the gap where the sheets are stacked. It is desirable. In addition, if the perforated convex portion is held in the gap and the projecting end of the perforated convex portion is projected from the sheet, only the projecting end of the perforated convex portion is preferably brought into contact with the paper sheet. In this case, the portion around the binding hole can be effectively protected during drilling.

  And as a further configuration constituting the elastic folded end according to the present invention, the sheet is formed by extending from either one of the convex portion support portion or the concave portion support portion in a direction orthogonal to the insertion direction in which the paper sheets are inserted. A tongue piece may be further included, and an elastic folding end may be further provided between the convex portion support portion or the concave portion support portion and the tongue piece. By doing so, the design freedom which positions an elastic folding | turning end can further be improved.

  In order to effectively determine the operating range of the convex portion support portion and the concave portion support portion, it extends from either the convex portion support portion or the concave portion support portion in a direction orthogonal to the insertion direction for inserting paper sheets. It is desirable to further provide a tongue piece formed in such a manner that the tongue piece is fastened to the other. Moreover, in order to fix the tongue piece effectively, it is preferable to fix the tongue piece by inserting it into the gap where the sheets are overlaid. In particular, if the tongue piece is fixed at a position where the perforated convex part and the perforated concave part can be substantially opposed to each other with a predetermined distance, the operation range between the convex part supporting part and the concave part supporting part is limited to a small extent. Therefore, it is possible to effectively suppress a decrease in elasticity when continuously operating.

  And as what is suitable as such an elastic support part, what was provided with paper can be mentioned.

  As a configuration in which such a punching tool can be effectively used, it is desirable that the punching recess is provided on a part of the cover of the file, and the punching protrusion is provided on a folded piece folded from a part of the cover.

  On the other hand, as another configuration in which the punching tool can be used effectively, a configuration in which a unitized punching tool that can be attached to a predetermined portion of the cover of the file is configured.

  In the case of such a file, the aspect which provided the punching tool integrally in a part of the cover body can be mentioned first.

  On the other hand, an embodiment including a cover body and a punching tool that can be attached to a predetermined portion of the cover body can be exemplified.

  When such an aspect is adopted, the cover body has a separation preventing portion that can prevent the perforation concave portion and the perforation convex portion from being separated from each other by a predetermined distance or more, so that the operation of the perforation tool is more accurate. In addition, since the punch does not operate more than necessary, it is possible to improve the durability of the punch.

  As a specific configuration of the file to make the punching tool easy to use, the punching tool is attached along the edge of the cover body, and the separation preventing portion is provided by extending from the edge of the cover body and folding it back. The thing which has a part can be mentioned. That is, the edge of the cover sheet can be used for positioning paper sheets and positioning when attaching a punch. As a specific configuration for suitably configuring the separation preventing portion, a configuration further including a fastening portion that extends from the cover body or the folded portion from a direction different from the folded portion and is fastened to the folded portion. be able to.

  According to the present invention, since the elastic support portion constituted by a single sheet is suitably separated by the accumulated elastic repulsion force, it is possible to remove the paper from the perforation recess or the perforation recess without providing a special repulsion mechanism. Leaves can be removed. By doing so, it is possible to provide a punching tool that can easily punch paper sheets while having a simple configuration.
