and it can be increased in its capacity. Further, it is possible
to see from the front how much waste has been collected in the waste
receptacle, and the waste receptacle 11 is easily taken out from
the front without moving the whole punch.
Description
- The present invention relates to a punch that is to pierce sheets of paper.
- Paper documents in general are easier to read when they are bound. One of known methods to bound sheets of paper is to use strings or metals after punching the sheets of paper.
- As a paper punch, there have been one comprising pipe-rod blades the rod of which is hollow and formed with a circular blade at the end thereof and a given stand to put sheets of paper thereon. In this punch, the pipe-rod blades are disposed above or under the sheets of paper and adapted to punch circular holes in the sheets of paper by pressing the pipe-rod against the sheets of paper. Circular punch wastes are discharged through an inner hole of the pipe-rod blade and collected in a waste receptacle attached.
- In a
conventional punch 1 shown in Fig. 14,anoperation stand 3 is provided on one end of abase 2 so as to be a continuation to thebase 2, and the other side of thebase 2 is used to put the sheets of paper thereon. In an upper portion of the operation stand 3, ahandle 5 is provided while pivoted on a rotatingshaft 4. Thehandle 5 is held approximately vertical by being biased with a spring but can be pulled toward thebase 2. - Furthermore, as shown in Figs. 14 and 15, a
projection portion 3a is formed on theoperation stand 3 which projects above the sheets of paper put on thebase 2. When the sheets of paper are set on thepunch 1, the sheets of paper are positioned by abutting one ends of the sheets of paper to astopper 6 that is on the far side of theprojection portion 3a and agauge 7 is used to set the widthwise position of the sheets. - At a
ceiling portion 3b of theprojection portion 3a, aplate 8 for pressing the sheets of paper with springs (not shown) and a pair of hollowpipe rod blades 9 looking downward through two holes formed in theplate 8 are arranged. Corresponding these two pipe rod blades a pair ofrecesses 2a are provided on thebase 2 below anddisc rod guards 10 made of a synthetic resin are disposed therein. Furthermore, awaste receptacle 11 is accommodated in theoperation stand 3. - As shown in Fig. 15, a
wheel gear 12 is connected to the rotatingshaft 4 connected to thehandle 5 and engaged with arack 13 that is capable of moving up and down. To a lower end of therack 13, acylindrical rod holder 14 to which thepipe rod blade 9 is to be fitted is connected. And thepipe rod blade 9 is inserted in an inner hole of therod holder 14 and fixed by ascrew 15 screwed laterally from the side of therod holder 14. - Furthermore, an upper portion of the inner hole of the
rod holder 14 is communicated with adischarge guide 16 opened to the back and with thewaste receptacle 11 in the operation stand through asliding plate 17. - In using this
punch 1, the sheets of paper are put on thebase 2 while abutting the front end of the sheets of paper against thestopper 6 and the sides of the sheets of paper against thegauge 7 for defining the widthwise positioning. Subsequently, thehandle 5 is turned toward the base, whereby theplate 8 and the pair ofpipe rod blades 9 descend, and are brought into contact with the sheets of paper and pressed against them. By further turning thehandle 5, thepipe rod blades 9 pierces the sheets of paper. - Then punch wastes stay in the hollow space inside of the
pipe rod blade 9, which increase in number by further punching. The punch wastes accumulated inside the blade are pushed up gradually to be discharged from the upper end of thepipe rod blade 9 and collected in thewaste receptacle 11 through thedischarge guide 16 and thesliding plate 17. - Now, the total weight of the
punch 1 is intentionally set heavy so as to stabilize the center of gravity of thepunch 1 against the force applied by the operation of turning thehandle 5. Furthermore, since thewaste receptacle 11 is accommodated in theoperation stand 3, it has to be done from the back of the punch (from the side opposite to the base 2) avoiding therotating shaft 4 and therack 13 to take out thewaste receptacle 11. Therefore, it is troublesome to take out thewaste receptacle 11 because the heavy punch has to be turned around so that taking out thewaste receptacle 11 becomes easier, or it has to be brought out into a broad space. In addition, since thewaste receptacle 11 is accommodated in theoperation stand 3, the volume of thewaste receptacle 11 has to be small, resulting in increasing the number of times of emptying the wastes. Moreover, since it is impossible to see from the front how much waste has been collected in the waste receptacle, the timing of emptying the wastes is difficult to judge. - The present invention has been made in view of the above, and an object of the present invention is therefore to provide a punch in which the volume of the waste receptacle to collect the punch wastes is increased and the waste receptacle can easily be taken out without moving the whole punch.
- In order to attain the above object, according to a first aspect of the present invention, there is provided a punch comprising a base and operation stands that have a handle to be pulled toward the base and are provided on one end of the base on which sheets of paper are put and punched by pipe rod blades depressed by pulling the handle toward the base, characterized in that an opening for discharging punch wastes is provided on a side of each of the operation stands above the pipe rod blades, and a waste receptacle for collecting the wastes therein is provided on the base so that the waste receptacle is communicated with the opening.
- According to a second aspect of the present invention, there is provided a punch characterized in that operation stands are provided on one end of a base for each arm of the handle, said arm being rotatably provided on a rotating shaft that is arranged along the horizontal direction of the operation stands, and a rod holder to which a cylindrical pipe rod blade is to be fitted is connected to the handle, and that a hole communicated with the cylindrical pipe rod blade is formed on one side of the rod holder, said opening is aligned with an opening formed on a side wall of the operation stand which is perpendicular to a handle turning plane and the punch wastes passing through the pipe rod blade are discharged from the opening.

- Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
- In a
punch 1 shown in Figs. 7 through 11, a pair ofoperation stands 3 are formed with an interval on an end of an approximatelyrectangular base 2 having a flat top face. The number of operation stands corresponds to the number of arms of thehandle 5. Thehandle 5 is provided rotatably on a rotating shaft 4 (see Fig. 5) arranged along the horizontal direction of the operation stand 3 so that thehandle 5 is moved in an arc from above toward thebase 2. Further, thehandle 5 is normally kept upright by being biased with a spring within theoperation stand 3. - On both sides of a portion of the
base 2 on which sheets of paper are put, agauge 7 is disposed in order to facilitate positioning for punch holes by aligning the edges of the sheets of paper to be punched. - A
rod holder 14 to which apipe rod blade 9 is to be fitted is provided on theoperation stand 3, and thepipe rod blade 9 is set such that it looks downward at the top face of thebase 2 below from aceiling portion 3b of theoperation stand 3. On the top face of thebase 2 under thepipe rod blade 9, a recessedportion 2a for arod guard 10 is provided, and a semi-circle portion on a side wall of the recessedportion 2a is tapered to form a taperedportion 2b that connects the top face of thebase 2 with the bottom of the recessedportion 2a. - A
waste receptacle 11 is disposed between a pair of operation stands 3. The side faces of thewaste receptacle 11 facing the operation stands 3 each have anopening 3c (see Fig. 4) communicated with the interior of thewaste receptacle 11. Thewaste receptacle 11 is made of a transparent resin so that the interior of thewaste receptacle 11 can be seen from the operator (from the front), and a shape that allows thewaste receptacle 11 to be easily taken out upward or toward the front (toward the base 2). - Next, details of the
waste receptacle 11 will be explained. - As shown in Figs. 1 through 3, this waste receptacle is composed of an open top
square container 18 and acover 19 thereof. Thecontainer 18 is provided with an engagement groove 18a in its inner perimeter that is overlapped with thecover 19. Inside thecontainer 18, there is a slope sloped toward the back of thecontainer 18, so that the punch wastes are easily accumulated in the rear bottom of thecontainer 18. Further, on the rear bottom of thecontainer 18, a positioning recessedportion 18b is provided to engage a projection (not shown) provided on thebase 2. - The
cover 19 is provided with aprojection 19a that projects downward and is positioned a little inside the perimeter of thecover 19 which is overlapped with thecontainer 18. On both sides of the front upper face of thecover 19, there are windows covered with ears (communication ports) 19 extended sideward, thereby obtaining communication with the interior of thecontainer 18. Formed on both sides of the rear upper face of thecover 19 aregroove portions 19c, which are to be loosely fit with linear projections 20 (see Fig. 4) of the side walls of the operation stands 3. - Next, the
operation stand 3 will be explained. - As shown in Figs. 4 through 6, side walls of each of the operation stands 3 have
rectangular openings 3c formed on projectedportions 3a. Above theopenings 3c, ahole 3d for supporting arotating shaft 4 is provided. On the rear portion of the side wall of each of the operation stands 3, thelinear projection 20 for holding thewaste receptacle 11 is provided. Now, in the operation stand, two side walls are used, but, since the outer side wall does not need theopening 3c, the opening is covered with an ornament plate 21 (see Fig.7). - The operation stand 3 holds the
rod holder 14 in a manner that allows therod holder 14 to move up and down, and thehandle 5 and therod holder 14 are connected with alink 22. In the lower limit position (approximately horizontal) of thehandle 5, the upper fulcrum of thelink 22 is located, in the horizontal direction, at a point between the center line of therod holder 14 and the perpendicular line drawn from therotating shaft 4. - Next, details of the
rod holder 14 and thepipe rod blade 9 will be explained. - As shown in Figs. 12A through 13B, the
rod holder 14 is shaped into an angular column and has on its bottom acircular hole 14a to which thepipe rod blade 9 is fitted. - The upper portion of the
rod holder 14 on the left and right is chipped and reduced in thickness. A communication hole 14b for thelink 22 is formed in this thinned portion, and a screw hole 14c for fixing thepipe rod blade 9 is provided below and perpendicular to the communication hole 14b. Formed in the middle of the side face of therod holder 14 is anopening 14d whose shape in section is like a fan with its apex set inward and the bottom outward. Theopening 14d is communicated with thecircular opening 14a formed in the bottom of therod holder 14. - Further, as shown in Figs. 13A and 13B,
vertical grooves 14e are provided at four corners of therod holder 14. This makes it possible for therod holder 14 to be guided vertically along a C-shaped frame (a resin made sliding guide) (not shown) of theoperation stand 3. - The
pipe rod blade 9 is, as shown in Fig. 12A, enlarged in diameter at a portion where it is fitted to therod holder 14 and, as shown in Figs. 12A and 13A, an L-shapedbracket 23 split at its tip fixes thepipe rod blade 9 to theholder 14. As seen in Fig. 12B, the tip thepipe rod blade 9 has edges, which makes an inner diameter of thepipe rod blade 9 at this portion reduced. However, the diameter of thepipe rod blade 9 is increased above this portion, whereby the wastes of punched sheets of paper smoothly passes through thepipe rod blade 9. - The
punch 1 of the present invention is structured as above and when punching sheets of paper, the sheets of paper are put on thebase 2 under thepipe rod blade 9 and, by flushing the edges of the sheets of paper with thegauge 7, the position to be punched is determined. - Then, by pulling the
handle 5, theplate 8 and thepipe rod blade 9 descend to hold and punch the sheets of paper. Thepipe rod blade 9 is pressed against therod guard 10 and cuts into it a little bit before the blade stops. The punch wastes of the sheets of paper are thus pushed into the interior of thepipe rod blade 9 and holes are punched in the sheets of paper. - The punch wastes pushed into the
pipe rod blade 9 gradually slide up as punching is repeated, and are discharged from theopening 14d of therod holder 14. The punch wastes are then discharged from theopening 3c of theoperation stand 3, received by theears 19 of thewaste receptacle 11 disposed by the side of theoperation stand 3, fall down the slope of thecontainer 18, and collected in thewaste receptacle 11. - Thus, since the
pipe rod blade 9 is made possible to move up and down with a simple link mechanism, the operation stand 3 provided for each arm can be made thin and, accordingly, onewaste receptacle 11 can be set between a pair of operation stands for a pair of arms. - Accordingly, the punch wastes are discharged from the side faces of the operation stands 3 and can be collected in the
waste receptacle 11 disposed by the side of the operation stands. The punch wastes collected in thewaste receptacle 11 can be seen from the outside, and, when emptying the wastes, only thewaste receptacle 11 can be taken out upward or toward the front (toward the base) without moving the whole punch. In addition, since the waste receptacle is located on thebase 2, the shape thereof is free to design, and its capacity can be increased as compared with the conventional type that is accommodated under thebase 2. - Further, when changing the
rod guard 10, the taperedportion 2b formed in the recessedportion 2a of thebase 2 will make it easier to attach or detach therod guard 10. - In addition, the number of the
pipe rod blades 9 and thearms 5a associated with the blades may be increased together with the operation stand 3 to make a punch capable of punching three or more holes. Then thewaste receptacle 11 has to be disposed every two adjacent operation stands 3. - Thus, according to the first aspect of the present invention, punch wastes are discharged from the side opening of the operation stand onto which the rotating shaft of the handle is pivoted and collected in the waste receptacle on the base. Therefore, the accumulated waste volume is easy to see and the waste receptacle can be detached from the near side without moving the whole punch. This makes the punch very user-friendly.
- According to the second aspect of the present invention, the operation stand onto which the arm of the handle, which is to operate the punch when punching sheets of paper, is pivoted is provided on the base with an interval for each arm. The waste receptacle can thus be disposed between the operation stands on the base. Further, the punch wastes are pushed through the pipe rod blade, moved toward the side opening of the rod holder, and discharged from the side opening of the operation stand. It is thus possible to collect the punch wastes in the waste receptacle disposed by the side of the operation stand. In addition, the shape of the waste receptacle is free to design and the capacity thereof can be increased.
- According to the third aspect of the present invention, the communication port of the waste receptacle makes it possible to securely collect the punch wastes discharged from the side opening of the operation stand. Moreover, how much waste has been accumulated is easily known and the waste receptacle can be removed without moving the whole punch, thereby making the punch very user-friendly.
- According to the fourth aspect of the present invention, since the waste receptacle is set between a pair of operation stands, the waste receptacle can be held to the side faces of the operation stands, and the openings of the operation stands and the communication ports of the waste receptacle may be connected easily by merely placing the waste receptacle. This makes the punch very user-friendly.
