Abstract

A combined device for fastening and punching holes in sheets, especially paper, in which a known fastening device containing a stapling arrangement (3) is integrated in a hole device comprising a hole punch (1) and die (2) arrangement.

Description

Combination device for stapling and punching sheets, in particular made of paper

The invention relates to a combination device for stapling and punching sheets, in particular made of paper, with a punching device consisting of punch and die arrangement.

It is generally known that there must be corresponding perforations for storing leaves in the customary order systems, through which a fastening to a bracket can take place. To this end, devices are often used which, in their essential structure, consist of a punch and die arrangement and which have been widely used in various embodiments.

Likewise, stapling devices are known, by means of which several sheets of paper can be combined. Both devices are used and handled independently of one another in the office area.

Proceeding from this, the invention has set itself the task of further developing these devices in order to improve their manageability during use.

This object is achieved according to the invention in that a combination device is proposed, in which the hole device is additionally known Stapling device is installed and integrated. The result is a combination device that contains the functions of the two individual devices. Here it is to be regarded as advantageous that the number of parts of a combination device is significantly less than the sum of two separate individual devices, due to the fact that certain parts can perform a function in both modes of operation. The consequence of this is that a substantial reduction in price becomes possible in the manufacture of the combination device, and, what is to be regarded as a further advantage, that only a single device remains on the desk or the like. is to be kept ready, which fulfills both the function "stapling" and "punching". Another consequence is the reduction of Eigenplatzbe- ^'needs for supplies, which in particular proves to be preferred if the device has to be, for example, carried on business trips.

Particularly advantageous developments of the invention are specified in detail in the subordinate claims. Claims 2 to 14 reproduce exemplary embodiments in which the punching device is optically predominant, since the stapling device is built into the lever plate in a fixed and / or removable manner, which is adjusted by the setting means from the "stitching" function to the "punching" function. is switchable. Furthermore, embodiments are proposed, in which the cap is integrated in the lever plate, but the magazine can be pivoted relative to this, or the lever plate can be folded up relative to the magazine, in the latter case the projections of each punch engage in elongated holes so that they cannot fall out and get lost when the lever plate is folded up. Through both embodiments, the magazine easily accessible, so that the staple stock can be supplemented particularly easily. In further developments, the magazine is connected to the base body via ratchet bars, which have the effect that when the lever plate is folded up, the magazine is automatically opened during its upward movement and is immediately accessible for loading. As known from the ^• the art, the stock is a staple Heftklammer¬ edge jerk slider on the staple guide to pressed, so that in each

Stroke movement of the plunger a staple is ejected. If, according to the invention, a spring is now attached to this clamp pressure slider, which is guided from there in the direction of the pivot bearing and then back again to the plunger arrangement, the spring is extended when the lever plate is opened and thus a force on the clamp pressure glider that this retreat, so that the staples can be inserted staple supply immediately, while after closing ^'the lever plate of the slider Klammerandruck¬ is pressed against the mervorrat Heftkla.

The special design of the setting means is specified in claims 9-15. The proposal according to claim 9 has a particularly high level of safety in handling, since the plunger is held on a catch with the help of a web used on it at the end of each stapling operation and thus for so long in it

Function is blocked until it returns to its starting position after pressing a trigger button. The triggering takes place in such a way that the plunger moves away from the catch and is thereby released. Unintentional triggering of the stapling process when punching or other manipulations of the The device according to the invention, for example when the operator's fingers accidentally come under the magazine and the lever plate is actuated, which would inevitably result in the penetration of a staple into the operator's fingers, is excluded under all circumstances. For this purpose, the release button must be pressed at the beginning of each stitching process and the ram must be released. An elegant structural solution consists in the use of a U-shaped spring, which is preferably fastened with the base to the lever plate and one (inner) leg of which is used as a plunger and the (outer) leg of which is used as the carrier of the release button.

Another embodiment of the setting means is specified in claims 11-13. Finally, claim 14 proposes the additional inclusion of further devices in the combination device, which are also often required when performing office work.

The configuration according to claims 9-12 hinge¬ relate to embodiments in which the stapling device is the optically predominant part, in which a punch and a punch die are arranged below the base body of the stapler.

Exemplary embodiments of the device according to the invention are shown in the drawings and are described in detail below.

1 shows a view of a first exemplary embodiment, for example for a table version Fig. 2 View of a second exemplary embodiment z. B. in Reise¬ execution

Fig. 3 is a fig. 1 corresponding embodiment, but with structurally differently designed adjusting means

As shown in FIG. 1 a, a lever plate 7 is pivotally mounted on the base body 6 of a perforating device at 30, which is always under the action of spring means formed from return springs 8 and from these in the direction of one by a stop 32 on the base body 6 limited raised rest position is affected. These return springs 8 are supported on the base body 6, are arranged coaxially with the punch 4 and the die 5 and act indirectly on the lever plate 7 via projections 33 (see FIG. 16), thereby simultaneously acting as a return spring are effective for the punch 4.

As FIG. 1 further shows, both the punch arrangement 1 (see in particular FIG. 1b) and the die arrangement 2 are provided in the base body 6. On the side 35 of the base body 6 opposite the insertion slot 34 for the papers to be punched, an elongated hole 26 is provided which runs parallel to a connecting line between the two punch punches 4 and has slightly enlarged areas 29 and 29a at its ends, which correspond in shape to the cross section of sliding bolts 27, ^" which protrude through the base body 6.

The sliding bolts are fastened to the underside of an intermediate piece 20 consisting of a sliding body. Stigt that is adjustable as an adjusting means 13 between an effective and an ineffective position, the extended areas 29 u. 29a having ends of the elongated hole 26 are effective as an end stop 24 or 25. Due to the oblong hole 26 of the base body 6 made of a plastic, which is slightly narrowed compared to the sliding bolt 27, a pleasant locking effect results when the intermediate piece 20 is displaced, below the base body 6, but still within a storage space 36 for the punched-out paper blanks, the sliding bolts 27 engage in a sliding piece 37, the same expediently consisting of shaft screws.

A metal plate is adjustably arranged on the upward-facing surface 22 of the intermediate piece 20, which has become generally known as a so-called staple former 23 of a staple device and is therefore not described in more detail. Due to the displaceability of the intermediate piece 20, the staple former 23 of the outlet opening 21 can be compared to a staple guide 19 which is a component of a magazine 10 provided for a staple supply 11. The clamp guide 19 also serves to guide and laterally support a plunger 14 which is part of a plunger arrangement 12 which is generally known in staplers and which is fastened in a cap 15. This cap 15 essentially consists of a one-armed lever which is pivotably mounted on the magazine 10 on a rotary bearing 31 and is supported relative to the latter by a support spring 16, such that the two parts are pressed against one another when they are pressed together Effect of the support spring 16 cause an ejection of a staple through the plunger 14. The opening angle between the cap 15 and the magazine 10 is limited for a rest position by a known and not shown locking stop 45, which is insurmountable for the purpose of opening the magazine.

The cap 15 and the magazine 10 form the essential parts of the staple arrangement 3, for which receiving means 9 are provided on part of the perforating device. This part is the one-armed lever plate 7 already described at the beginning, on the underside of which an insertion shaft 17 is formed, which is essentially adapted to the shape of the cap 15, in such a way that the latter with the magazine 10 from the side facing the Insert slot 34 is opposite, can be pushed under the lever plate 7.

To fasten the cap 15 in the insertion shaft 17, the latter has fastening means which, on the one hand, consist of a receiving pin 38, which engages in an adapted recess 39 of the cap 15, and, on the other hand, of latching means 18, which are behind a latching edge 40 Cap 15 can snap, exist. The latching means 18 consist of a latching lug 41, which is integrally formed on the insertion shaft 17 and with suitably elastic zones 46 and furthermore has an actuating lug 42 for manual latching.

Lateral stops 43 are formed on the base body 6 and serve to limit the hole working stroke of the lever plate 7. This working stroke, which the lever plate 7 always carries out together with the staple arrangement 3, is dimensioned such that the outlet opening 21 of the magazine 10 cannot touch the surface 44 of the base body 6 if that Intermediate piece 20 is in its ineffective starting position, which also means that there is no ejecting function for a staple, since there is no relative movement between magazine 16 and cap 15 (see the dash-dot-dash lines in FIG. 1 a). This functional position corresponds to a "punch" function.

If, however, the intermediate piece 20 with its clip former 23 is pushed into the range of movement of the magazine, the outlet opening 21 of the same hits the clip former 23 for a “stapling” function (see the dash-dotted lines in FIG. 1 a), whereby the plunger 14 can become effective by folding the magazine 10 and the cap 15 together for ejecting a staple. The height of the intermediate piece 20 is dimensioned such that the extension of the clip and the shaping of the clip is completed at the latest when the working stroke of the lever plate 7 is limited by the stops 43 on the base body 6.

With the "stapling" function, the punch 4 also perform its working stroke, but this is absolutely harmless to the device. It is of course readily possible to design the arrangement according to the invention differently without changing the subject matter of the invention.

So z. B. the cap of the staple arrangement can be dispensed with if the plunger and the support spring are fastened directly to the lever plate within the insertion slot and the magazine is arranged on the same with a latching rotary bearing. In the above-described embodiment according to FIG. 1, the arrangement according to the invention is optically characterized by a punching device, as a result of which it can be used particularly as a desk device due to the predetermined size.

However, as FIG. 2 shows, it is also possible to design the arrangement according to the invention in such a way that the optically predominant part is a stapling device, which then in particular allows a smaller overall size.

Here, a stapler arrangement 103 known per se is provided, which consists of a base body 130, which is provided with a preferably changeable staple former 123, not shown, a magazine 110 with the associated parts, such as staple guide 119 and the outlet opening 121, and a cap 115 with the tappet arrangement 112, these three parts being connected to one another in an articulated manner at their ends via rotary bearings 131 and 131a, between the cap 115, which is used for manual actuation, and the magazine 110 Support spring 116 is provided, which spreads the two parts apart up to a latching stop 141, which, however, can be easily overcome for access to the staple supply 111 (not shown in detail) for opening the cap 115. Also between the base body 130 and the magazine A support spring 133 is effective, which always holds the magazine 110 in a raised position relative to the clamp former 123 ¬ to hold the latching stop 141a, which means that during a stapling process, as is generally customary, first the support spring 133 and then the support spring 133 and then the support spring 116 are compressed for a staple extension. Hence is then the support spring 116 is made more effective than the support spring 133.

In this exemplary embodiment, a receiving body 132 is integrally formed underneath the base body 130, which has approximately the base body 6 of the exemplary embodiment according to FIGS. 1 with punches

104 and a matrix arrangement 102 with perforated matrices

105 has. Furthermore, the receiving body 132 forms an insertion slot 144 for the insertion of

Sheets of paper and a storage space 145 for receiving punched-out paper blanks, which can be locked by means of a cover 142 or closed by friction.

The receiving body 132 also has bearing means 143 for a drive rocker 134, which consists of a steel bracket and which is pivotably supported by its longitudinal web 146 in the bearing means 143. Parallel to the longitudinal web 146, a rod 149 is welded to the drive rocker 134, the ends 147 of which engage positively in the recesses 148 of the punch 104.

The drive rocker 134 is constantly under the influence of a return spring, which can consist of a leaf spring and, in this embodiment, simultaneously takes over the function of the support spring 133 for the magazine 110 of the stapler arrangement 103.

A rod 136 engages on the rod 149 of the drive rocker 134, which articulates through an opening 135 in the base body 130 by means of a latching connection (not shown in more detail) and thereby acts with the lower surface 150 of the magazine 10. Connection can be made in such a way that the drive rocker 134 and thus also the punches also perform a working stroke in each yeast operation, which then takes place relatively smoothly against the action of the support spring 133, since the punches 104 are missing of the paper to be punched there is no additional resistance.

In order to prevent a "punching" operation in the case of a considerably greater resistance for the support spring 116 acting between the magazine 110 and the cap 115 in the paper inserted into the insertion slot 144, a staple 114 is provided by the plunger 114 an adjustment means, consisting of a locking device 137, is provided by means of which a rigid connection between the cap 115 and the magazine 110 can be produced.

This locking device 137 consists of a bolt 138 which is mounted on the cap 115 between an effective and an ineffective position. The bolt 138 of a further cap is seated displaceably on the cap 115 comprises, one, but preferably two, locking edges 139 with which it is in the effective range of a locking surface 140 brihgbar ^'which is seen vorge on the magazine 110 and of whose upward-facing surface 151 exists. The locking edges 139 are part of tongues 152, which are effective between the side walls 153 of the cap 115 and the plunger 114.

The bolt 138 can be provided with means which ensure a locking function for both the effective and the ineffective position. This means can be made of generally known elements, e.g. B. consist of a detent spring, and are therefore not shown in more detail in the drawings.

In the exemplary embodiment according to FIGS. 2, the actuating element, in this case the cap 115, performs a smaller working stroke than during "stapling", since the extension function of the plunger 114 for the staples by locking the magazine 110 and the like Cap 115 is prevented.

_**

In the embodiment according to FIGS. 1, however, the actuating element (lifting plate 7) always carries out an equally large working stroke.

In the exemplary embodiment according to FIGS. 2, it is of course also possible to design the adjusting means (locking device 134) in such a way that the drive rocker 134 is actuated directly by the cap 115 if an adjustable actuating lug provided therefor ent ent ent speaking length.

FIG. 3 shows a further exemplary embodiment of the combination device according to the invention in cross-sectional representation, which in its basic structure is similar to that already described in FIG. 1. The parts common to the two figures are provided with the same reference numerals for reasons of clarity and they are not to be explained again in the following in the description of FIG. 3 for reasons of simplification, instead the differences are focused on.

The most obvious difference is the real Positioning of the adjusting means, which are formed in FIG. 3 from a spring 158 of U-shaped configuration, which is fastened in its base region to lever plate 7 and is provided on its (outer) leg with a release button 156, which on the opposite side horizontal (inner) leg indicates, which performs the function of the plunger (14) in a manner known per se. The decisive factor is the notch 154, which is to be directed outwards towards the opposite leg and which engages behind a web 155 running perpendicular to the plane of the drawing, when the magazine 10 reaches the upper deposit during the stapling process. As long as the magazine 10 is then held in this position by the catch 154, further stapling operations cannot be carried out.

Only when the trigger button 156 is pressed, which engages through the clamp guide 19 approximately in the central region and thereby bends the plunger 14 inwards in an elastic manner, the catch 154 can pass the web 55 with the support of the support spring 16 and in this way into it return to the lower starting position. The stapling device is then ready for use again, since the staple supply can be moved forward by the staple pressure slide 157 in the magazine towards the staple guide 19 and the end of the staple can be grasped, separated and inserted by the plunger 14 during the next stapling process. The decisive advantage of this embodiment is to be seen in the fact that when the magazine is engaged, the stapling process is inadvertently triggered and thus injuries to the operator when the combination device is otherwise handled, such as, for. B. when punching is excluded.

Since the transition from the functional position "stapling" to "punch" and vice versa is no longer carried out by moving a sliding body provided with the clamp former 23 (see FIG. 1), this is fixed in the base body 6.

5

Another difference is the fact that

Attachment of the spring 158, which is attached at one end to the clamp pressure slide 157, from there in

Direction towards the rotary bearing 31 and then back to the tappet arrangement 12. In the closed i.e. In the working state, this spring 158 is subjected to compression, as a result of which the clamp pressure glider 157 is pressed against the staple supply 11, whereas in the open state, i.e. τ_5 when lever plate 7 and magazine 10 are folded apart, the spring 158 is subjected to tension and

. As a result, the spring pressure slider 157 is pulled back, and therefore the staple supply 11 is released and can be easily supplemented.
