Description

  The present invention relates to a stapler provided with a storage unit for spare staples in addition to staples loaded in a magazine.

  In general, this type of stapler is provided on the handle by sandwiching the paper to be bound between a base having a clinch groove formed at the tip and a magazine loaded with a plurality of staples, and pressing the handle on the upper side of the magazine toward the magazine. The leading staple in the magazine is driven out with a driver plate to penetrate the paper to be bound, and the leg of the penetrated staple is bent by the clinch groove of the base and bound.

  By the way, the staples are loaded in the magazine, and when the leading staple is ejected from the ejecting portion at the leading end of the magazine, the subsequent staples are successively supplied to the ejecting portion by the feeding means. However, there is only a storage space in the magazine that can be loaded with two linked staples in which 50 staples are linked, that is, a total of 100 staples. In an office where a lot of binding operations are performed, 100 staples are consumed in a short time, and the user must always be aware of the consumption state of the staples in the magazine.

As an improvement measure, there has been proposed a method in which a spare staple storage portion is formed in the upper surface of the handle and a spare staple is stored therein. A cover is provided in the storage portion so as to be opened and closed by a hinge.

  However, it is difficult to keep spare staples to be reloaded at hand. A courier worker or train crew may carry a stapler in a pocket for binding slips or tickets, and use it out of the pocket if necessary. In the staple configured as described above, the cover may be caught in a pocket and opened carelessly, and the staple stored in the storage unit may fall to the ground and be scattered. In this case, loose staples may become unusable or may take time to load, which may hinder business.

  As a solution to cope with this, it is conceivable to add a lock device that locks the cover in a closed state. However, if components for the lock device are added, the number of components increases and the cost increases.

  The present invention is provided with a spare staple storage unit that can solve the above-mentioned problems and can effectively prevent the staple stored in the spare staple unit from being inadvertently opened and falling and scattered. The challenge is to provide a stapler.

In order to solve the above problems, a stapler provided with a preliminary staple storage unit according to the present invention has a stapled sheet sandwiched between a base having a clinch groove formed at the tip and a magazine loaded with a plurality of staples. By pushing the handle to the magazine side, the top staple in the magazine is driven out with a driver plate provided on the handle to penetrate the paper to be bound, and the leg portion of the penetrated staple is bent and clinched in the clinch groove of the base, and then bound. In the stapler with an opening formed in the upper surface of the handle for the spare staple storage part,
A convex portion provided on both sides of one of the cover and the handle for covering the housing section in the elongated hole provided on the other sides, and is slidably supported along the longitudinal direction of the handle One move times When the cover is slid to one end, the cover and the handle are engaged, and when the cover is slid to the other end, the engagement is released and the cover can be rotated. On the back surface of the knives, a pressing portion comprising two ridges formed at the same interval as the interval between the leg portions of the staple is integrally formed, and is stored in the preliminary staple storage portion by the pressing portion when the cover is closed. and thereby to hold the staples, the front end of the cover, when said cover is slid to the end of one the engagement with the engagement groove formed on the inner side of the housing part front end side of the handle Characterized in that the protruding Rukakarigohen.

In addition, a protrusion is formed in the middle part of the elongated hole so that the convex part moves tightly compared to both sides thereof, and when the convex part moves along the elongated hole, It is preferable to form a slit for absorbing deformation parallel to the elongated hole .

  According to the first aspect of the present invention, the cover that covers the spare staple storage portion can be rotated and slid, and when the cover slides to one end, the engagement piece at the tip of the cover is in the engagement groove of the handle. When the cover is engaged and slid to the other end, the cover can be turned only after the engagement is released. Therefore, the cover is not released unless a sliding force and an opening / closing force are applied.

  Even when the stapler is carried in a pocket and taken out of the pocket as necessary, the staple of the above configuration effectively prevents the cover from being caught in the pocket and being opened carelessly. be able to.

In addition, the spare staple stored in the spare staple storage portion is pressed by a presser portion formed of two protrusions formed at the same interval as the interval between the staple legs when the cover is closed. Because it is, it does not rattle and can be held down reliably.

According to the invention which concerns on Claim 2, while forming the protrusion which makes the said convex part move firmly compared with the both sides in the intermediate part of the said long hole, the said convex part is along the said long hole The slit that absorbs the deformation of the protrusion when moving is formed in parallel with the elongated hole, so that the convex part of the cover slides along the elongated hole so that the cover is lightly locked Thus, it is possible to reliably prevent the cover from being opened unexpectedly.

  FIG. 1 shows a side view of a stapler according to the present invention. In the figure, reference numeral 1 is a base, 2 is a magazine, and 3 is a handle. These base 1, magazine 2 and handle 3 are supported by the same spindle. A clinch groove 4 is formed at the tip of the base 1, and a plurality of staples (not shown) are loaded in the magazine 2, and a punching portion 5 for punching the leading staple is formed at the tip.

  The handle 3 is formed in a U shape whose cross section is opened downward, the outer side is formed of a synthetic resin, and the driver plate 8 is formed at the inner end. Further, a staple presser 9 is provided at the lower portion of the handle 3 so as to be rotatable within a certain range.

  With the above configuration, the stapled paper 10 is sandwiched between the base 1 and the magazine 2 and the handle 3 on the upper side of the magazine 2 is pressed against the magazine 2 side. The leading staple can be driven out to penetrate the paper to be bound 10, and the leg portion of the penetrated staple can be bent and bound by the clinch groove 4 of the base 1.

  Next, a preliminary staple storage portion 11 is formed in the upper surface of the handle 3. As shown in FIG. 2, the width and depth of the spare staple storage unit 11 are formed such that the two linked staples 12 face each other vertically and can be stored in a state where the legs are in contact with each other. Yes. The length of the preliminary staple storage unit 11 is formed such that the two linked staples 12 can be stored in a state where they are continuous in the front-rear direction. Accordingly, the spare staple storage unit 11 can store four linked staples 12 (total of 200 staples). Since two linked staples 12 can be loaded in the magazine 2, a total of 300 spare staples can be held in the stapler.

  The preliminary staple storage unit 11 is covered with a synthetic resin cover 13. That is, both side walls are formed on both side edges of the preliminary staple storage portion 11 of the handle 3 by the stepped portions 14 that are dropped inward by the thickness of the cover 13. A long hole 15 which is long in the longitudinal direction of the handle 3 is formed on the base side of the both side walls 14. As shown in FIG. 3, a triangular protrusion 16 is formed in the middle of the elongated hole 15, and the elongated hole 15 has a width of the protruding portion 16 smaller than the width on both sides thereof. Is formed. A slit 17 parallel to the elongated hole 15 is formed in the lower portion of the elongated hole 15.

  Correspondingly, boss-like convex portions 18 projecting inward are formed on both sides of the base portion of both side pieces of the cover 13. The convex portion 18 engages with the elongated hole 15, whereby the cover 13 can be rotated around the convex portion 18, and the convex portion 18 moves along the elongated hole 15. 13 can slide back and forth. In addition, since the protrusion 16 is formed in the intermediate part of the long hole 15, when the convex part 18 moves beyond the protrusion 16, it is comprised so that it may become tight. When the protrusion 18 exceeds the protrusion 16, the deformation of the protrusion 16 is absorbed by the slit 17.

  Further, an engagement piece 19 is formed to protrude at the tip of the cover 13, and when the cover 13 slides to the tip side, the engagement piece 19 is formed on the inside of the handle 3 on the tip side of the storage portion. 20 to be engaged.

  Further, as shown in FIG. 2, two ridges 23 are formed on the back surface of the cover 13 as a pressing portion for pressing the connected staple 12 stored in the preliminary staple storage portion 11 when the cover is closed. The distance between the protrusions 23 may be the same as the distance between the leg portions of the staple. Note that the presser portion may have a structure that can hold staples. Instead of a ridge, it may be a single protrusion.

  Next, how the stapler is used will be described.

  First, when the bound paper 10 is bound, the cover 13 is closed as shown in FIG.

  As a result of repeating the binding operation, when the remaining amount of staples in the spare staple storage unit 11 is reduced or no longer exists, the cover 13 is first slid backward as shown in FIG. After disengaging the engagement piece 19 from the inside of the spare staple storage unit 11 of the handle 3, the cover 13 is rotated and opened as shown in FIG. The magazine 2 may be replenished. After replenishment, the cover 13 may be closed and slid forward, and the engagement piece 19 at the tip of the cover 13 may be engaged with the inner engagement groove 20 of the storage portion 11 of the handle 3.

  As described above, the cover 13 covering the spare staple storage unit 11 can be rotated and slid. When the cover 13 is slid to one end, the cover 13 and the handle 3 are engaged, and the other end is When the slide is performed, the cover 13 can be turned only after the engagement is released. Therefore, the cover 13 is not released unless a sliding force and an opening / closing force are applied.

  In addition, a courier worker or a train crew may carry a stapler in a pocket for binding slips or tickets, and use it out of the pocket if necessary. Since the stapler 1 does not open unless the cover 13 is slid once, the cover 13 is caught in the pocket and opens carelessly, and the connected staples 12 stored in the spare staple storage unit 11 fall to the ground and are scattered. It is possible to effectively prevent inconveniences such as

  When the convex portion 18 of the cover 13 slides along the long hole 15, the cover 13 is lightly locked by making it move tightly in the middle portion, so that the cover 13 can be opened more reliably due to unforeseen reasons. Can be prevented.

  FIG. 6 is an explanatory view of another slide mode of the cover, and shows a portion corresponding to part A in FIG. 1 in a cross-sectional view. The convex portions 18 on both side bases of the cover 13 are the lengths of both side edges of the handle 3. It is configured to be engaged in the hole 21, and a mountain-shaped protrusion 22 is formed at the middle part of the groove bottom of the long hole 21.

  Also in the case of the above configuration, when the convex portion 18 slides along the elongated hole 21, an effect that the intermediate portion is moved tightly is obtained.

  The boss-like convex portions 18 may be formed on the base side of both side walls of the spare staple storage portion 11 of the handle, and the elongated holes may be formed on both sides of the base portion of both side pieces of the cover. Instead of the boss, a shaft that penetrates both side pieces of the cover 13 may be used.

  Further, when there is a pressing portion 23 on the back surface of the cover 13, it is possible to prevent rattling by pressing the staples in the preliminary staple storage portion. In this case, the cover 13 does not necessarily have a slide structure.

It is a side view of the stapler concerning the present invention. It is a cross-sectional view of the principal part of a storage part. It is an enlarged view of the A section of FIG. It is a side view of the state which made the said stapler slide. It is a side view in the state where a cover was opened. It is another slide aspect explanatory drawing of a cover.
