  In general, the number of holes that the punch can make in the sheet at the same time is the same as the number of punch blades that the punch has. However, sometimes you want to drill more holes than the number of punch blades. If it is intended to drill more holes than the number of punch blades, the drilling operation must be performed a plurality of times. For example, when it is desired to make four holes in the sheet, but there are only two hole punches at hand, two holes must be punched using the two hole punches. However, it is troublesome to perforate a plurality of times while changing the position of the punch with respect to the sheet. In addition, since there is no effective means for adjusting the positional relationship between the previous drilling location and the subsequent drilling location, it is difficult to drill all the holes at appropriate locations. In such a case, if a four-hole punch is separately prepared, all holes can surely be drilled at appropriate locations. However, users with few such opportunities must also prepare or purchase a 4-hole punch just for that few opportunities.

  In view of the above problems, an object of the present invention is to further enhance the convenience of punching.

  In order to achieve such an object, the present invention takes the following measures. In other words, the connector according to the present invention has a main body, a lever that is rotatably supported by the main body, a punch blade that advances and retreats as the lever rotates, and a gauge groove that supports a gauge for positioning the sheet. The plurality of punches are connected to each other by using the gauge grooves. The punch device according to the present invention includes a plurality of the punches and the coupling tool.

  With the above configuration, a plurality of punches can be arbitrarily arranged to make a large number of holes in the sheet. Moreover, since the relative positional relationship between the plurality of punches can be fixed by the presence of the coupler, it is easy to drill all the holes at appropriate locations. Of course, if the connection is released, each punch can be used alone. In this way, the convenience of punching is further enhanced. Furthermore, in the present invention, it is possible not only to suitably position the punch relatively by attaching the coupling tool to the main body using the gauge groove provided in most of the existing punches, but most of the existing punches. It is possible to configure the punching device by applying the connector without any improvement. By doing so, the user does not have to separately prepare a punch having a large number of holes, and in particular, if there are two or more punches of the same kind to form a punching device having a large number of holes, the punch can be easily obtained. An apparatus can be provided.

Furthermore, the connector according to the present invention includes an insertion portion that is inserted into the gauge groove, and an interposed portion that is provided between the plurality of punches to provide a predetermined interval .
In such a case, when the punch is reliably positioned by inserting the insertion portion into the gauge groove, the punching device having a large number of holes is provided by the interposed portion having the predetermined interval. In addition, a predetermined hole interval can be reliably ensured.

In order to enable the interposition part to reliably provide a predetermined interval, it is preferable that the interposition part has a contact part that contacts the side edge of the main body to position the punches.

  In order to ensure that the insertion portion is fixed to the main body more reliably, the insertion portion is provided with an engagement protrusion and an engagement hole is provided in the main body, and the engagement protrusion and the engagement hole are engaged with the concave and convex portions. It is preferable that the retaining means is constituted by combining them.

  The punch device and the connecting tool according to the present invention connect one punch and another punch so that the punch blades of one punch and another punch are aligned substantially symmetrically, and the punch in a state where these punches are connected. If the mark indicating the symmetry axis of the blade arrangement is attached to the connector, the center line of the sheet and the symmetry axis of the punch blade arrangement can be aligned and the holes can be drilled. Become.

  It is preferable that the connecting tool connects one punch and another punch so that punch blades of one punch and another punch are aligned at substantially equal intervals.

  If the punch has two punch blades and can punch two holes at a time in a sheet, the punch can be used as a two-hole punch by itself and if two are connected, a four-hole punch device Can be used as

  According to the present invention, a plurality of punches can be arbitrarily arranged to make a large number of holes in the sheet.

In addition, the relative positional relationship between the plurality of punches can be fixed due to the presence of the coupler, and it is easy to drill all the holes at appropriate locations. Of course, if the connection is released, each punch can be used alone. In this way, the convenience of punching is further enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the punch device P in the present embodiment includes two punches p, and the punch p is rotatably supported by the main body 1 and the main body 1 as shown in FIG. 2. And a punch blade 3 indicated by a broken line that moves forward and backward as the lever 2 rotates. The lever 2 is attached to the upper part of the main body 1 via the rotation shaft 4. The punch blade 3 is supported near the base of the lever 2, that is, in the vicinity of the rotating shaft 4, and advances and retreats in the vertical direction as the lever 2 rotates, and penetrates the sheet from above and punches. The illustrated example is a so-called two-hole punch, in which two punch blades 3 are arranged at the base of the lever 2. The main body 1 includes a base 11 that has a substantially square shape in plan view and supports the lever 2 via the rotation shaft 4, and a cover 12 that is attached to the lower portion of the base 11. The cover 12 has a shape corresponding to the shape of the base 11, and the peripheral edge on the upper surface side protrudes upward. When the cover 12 is attached to the base 11, the lower part of the base 11 is accommodated in the protruding region. A section (perforation scrap) of the sheet cut by the punch blade 3 at the time of punching is discharged below the base 11 through a through hole (not shown) formed in the base 11. The cover 12 receives the discharged perforated waste. The cover 12 is detachable from the base 11. If the cover 12 is detached, the perforated waste can be discarded.

  Further, as shown in FIG. 2, the punch p includes a gauge G for positioning the sheet at the time of punching as a separate member from the main body 1, and a gauge G on the lower surface side of the cover 12. Is provided with a gauge groove 13 for supporting the. Insertion ports 131 are provided on both side edges of the cover 12, and tapered side edges 121 are provided on the periphery of the insertion port 131. As shown in FIG. 4, in order to regulate the lower surface side of the gauge G so that the gauge G slides properly without being detached from the gauge groove 13, from the lowermost portion of the opposing side wall of the gauge groove 13 in the longitudinal direction. A plurality of protrusions t are projected at substantially equal intervals. And the cross-sectional shape of the gauge G is made into the reverse convex shape formed by forming the thin part g which can be inserted in the clearance gap between the upper surface of the said protrusion t, and the groove bottom of the gauge groove 13 in the width direction both ends. An engagement hole 132 is provided in the vicinity of the insertion slot 131 of the gauge groove 13 (FIG. 4). The engagement hole 132 will be described in detail later. Note that the gauge G, the gauge groove 13, the base 11, the cover 12, the lever 2, the punch blade 3 and the like can be configured in the same manner as existing punches.

  In the present embodiment, the punch device P as described above includes a connecting tool 20 for connecting the punch p as a member separate from the punch p. More specifically, as shown in FIGS. 1, 3, and 4, a connecting tool 20 for connecting to another punch p is attached by using the gauge groove 13. The connector 20 is an integrally molded product made of, for example, resin.

  The connector 20 has a symmetrical shape as shown in the figure, and more specifically, an interposition part 21 is arranged at the center thereof, and an insertion part 22 that protrudes from the left and right side edges of the interposition part 21 is provided. is doing. The insertion portion 22 has a reverse convex cross-sectional shape that is substantially the same as the gauge G described above, and has thin portions 222 at both ends in the width direction. Therefore, when the insertion portion 22 is inserted into the gauge groove 13, the lower surface side is restricted by the projection t like the gauge G, and can be suitably slid without being detached from the gauge groove 13. An abutting portion 211 that abuts a tapered side edge 121 adjacent to the insertion slot 131 of the gauge groove 13 is formed at a side edge portion of the interposition portion 21 where the insertion portion 22 protrudes. . A mark 212 is provided at the center of the interposition part 21. An engaging protrusion 221 is arranged on the upper side of the insertion portion 22 in the vicinity of the rising position.

  Before connecting one punch p and another punch p, the gauge G inserted in the gauge groove 13 of one punch p and the other punch p is pulled out in advance. Thereafter, the insertion portion 22 of the connector 20 is inserted into the insertion slot 131 of the gauge groove 13 where one punch p and the other punch p face each other until the contact portion 211 contacts the side edge 121. As a result, one punch p and another punch p are connected in a state where they are separated from each other by the width dimension of the interposition part 21. At this time, as shown in FIGS. 4 and 5, the engagement hole 132 provided in the portion from the side edge of the gauge groove 13 and the engagement protrusion 221 are engaged with each other, and the retaining means R is configured. Yes.

  In the present embodiment, the shape and dimensions of the connector 20 are set so that the punch blades 3 of the punch device P are aligned at substantially equal intervals in a state where a plurality of punches p are connected. That is, the punch blades 3 of the punch device P connected via the connector 20 are arranged symmetrically. An axis of symmetry of the arrangement of the punch blades 3 in a state where a plurality of punches p are connected is indicated by a mark 212 attached to the connector 20. The mark 212 is provided at the center of the connector 20, that is, at the center of the interposition part 21. By aligning the center line of the sheet with the mark 212, a plurality of holes can be formed symmetrically with the center line of the sheet. The center line of the sheet may be confirmed by a ruled line printed in advance, or a fold line formed when the sheet is folded in half may be used.

  If the concave-convex engagement of the above-described retaining means R is released by pulling the insertion portion 22 out of the gauge groove 13 by applying a certain force or more, the connection between the punch p and the connector 20 can be released. Needless to say, the unconnected punches p can be used alone. When the punch p is not connected, it is preferable to insert the gauge G into the gauge groove 13 instead of the connector 20.

  With this configuration, according to the present embodiment, a plurality of punches p can be arbitrarily arranged and a large number of holes can be formed in the sheet. Further, the presence of the connector 20 makes it possible to fix the relative positional relationship between the plurality of punches p, and it is easy to drill all holes at appropriate locations. Of course, if the connection is released, the punch p can be used alone. Furthermore, by attaching the connector 20 to the main body 1 using the gauge groove 13 provided in most of the existing punches such as the punch p, not only can the connector 20 be suitably fixed, The connector 20 can be applied to almost all existing punches without any improvement. In addition, if a connecting tool 20 that conforms to the specifications of an existing punch such as the punch p that has already been sold is newly produced, the convenience of the existing punch can be improved. By doing so, the punch apparatus P can be simply provided by using two punches p having two holes.

  Further, since the connector 20 includes an insertion portion 22 to be inserted into the gauge groove 13 and an interposition portion 21 that is provided between the plurality of punches p to provide a predetermined interval, the insertion portion 22 is inserted into the gauge groove 13. By being inserted, it is securely fixed to the punch p, and when the punch device P is constituted by the interposition part 21 having a predetermined interval, a predetermined hole interval can be reliably ensured.

  In order for the interposition part 21 to provide a predetermined interval with certainty, the interposition part 21 is provided with an abutment part 211, and the contact part 211 abuts against the side edge 121 to position the punches p, and the insertion part In order to ensure that 22 is engaged and fixed to the main body 1 more reliably, an engagement protrusion 221 is provided in the insertion portion 22 and an engagement hole 132 is provided in the gauge groove 13. The hole 132 constitutes the retaining means R by engaging with the concave and convex portions. By this retaining means R, the connecting tool 20 is securely attached to the punch p as compared with the state in which the insertion portion 22 is simply inserted, so the handling of the punch device P in the connected state is facilitated, and the user Can safely use the punching device P without worrying about the omission of the punch p.

  In addition, according to the present embodiment, one punch p and another punch p are connected so that the punch blades 3 of one punch p and the other punch p are arranged substantially symmetrically, and these punches p are connected. A mark 212 indicating the axis of symmetry of the arrangement of the punch blades 3 in this state is attached to the connector 20. With this mark 212, the center line of the sheet and the axis of symmetry of the arrangement of the punch blades 3 can be aligned and the hole can be accurately drilled.
