 Device for punching and filing objects such as sheets of paper and the like

The invention relates to a device according to the preamble of the independent claim. In particular, the invention relates to a device which, on the one hand, permits the insertion and filing of paper sheets in a folder, but on the other hand can also be used as a punch to create the perforation in the paper sheets.

Different devices for filing are known from the prior art, which also enable perforation of paper sheets.

For example, filing devices are known in which the holding brackets are divided and designed to be openable in a conventional manner, the two ends of the bracket parts serving as a punching device. With such constructions it is in the However, it is difficult in practice to precisely locate the holes in the paper sheet at a desired location.

Furthermore, constructions are known in which one-piece brackets have a punching device at one end. Punching the sheets may be simplified with these designs, but these designs make it difficult to insert the sheets for filing.

The object of the invention is now to overcome the disadvantages of the prior art

overcome and in particular to provide a device for punching and filing objects, such as sheets of paper or inserts, which is easy to use.

The object of the invention is particularly by the features of

independent claim solved.

The invention relates in particular to a device for punching and filing objects such as paper sheets or inserts, comprising the following components:

- a base which is attached or attachable to a folder or to a folder cover,

 - At least two holding brackets for holding the objects, the holding brackets being constructed in several parts and each comprising a pin and a bracket, the pin having a punching end for punching out a hole by inserting it into a punching opening and an insertion end for releasing an insertion opening for inserting perforated objects having,

 - An actuating mechanism, by the actuation of which the device can optionally be brought into a closed position, an open hole position, a closed hole position and an open insertion position.

It is preferably provided that the actuating mechanism runs along the

Main extension direction of the base includes movable slide for releasably attaching the pins to the base. If necessary, it is provided that in the closed position, the pin is coupled to the base at its punching end on each retaining bracket and rests with its insertion end at the end of the bracket in order to form a closed retaining bracket.

If necessary, it is provided that in the open hole production for everyone

Holding bracket the punching end of the pin is arranged lifted from the base and between the base and the punching end a hole for inserting and punching an object is free and the pen is attached with its insertion end to the end of the bracket.

If necessary, it is provided that in the closed position of the hole, the punching end of the pin for punching a hole is inserted into the base and the pin with its insertion end at the end of the bracket

is appropriate.

If necessary, it is provided that in the inserted position the between the

Inserting end of the pin and the end of the bracket, an insertion opening is kept free and the punching end of the pin is coupled to the base.

If necessary, it is provided that the pins each have at least one holding groove running parallel to the main direction of extension of the base in the region of the punching end, that the respective pin is coupled with its punching end to the base and attached to it when the slide engages in the holding groove, and that the respective pin can be removed from the base when the slide is pulled out of the holding groove.

If appropriate, it is provided that the slide for each holding bracket comprises a holding contour which runs along the main direction of extension of the base or along the direction of movement of the slide and which has the following elements in succession along the direction of movement:

a first holding extension for fixing the punching end of a pin by engaging in the holding groove in the closed position, a release opening for releasing a movement of the pin from the base into the open hole position,

 - A second holding extension for fixing the punching end of the same pin by engaging in the holding groove in the inserted position.

If necessary, it is provided that each retaining bracket has a snap lock that can be released by overcoming a holding force for the releasable connection of the respective

Grips the end of the pin with the end of the bracket.

If appropriate, it is provided that the actuating mechanism comprises a control contour and a control cam scanning and / or actuating the control contour for the controlled movement of the device when the actuating mechanism is actuated.

If necessary, it is provided that the actuating mechanism has a pivotably arranged actuating lever for manual actuation of the actuating mechanism, the actuating lever on the one hand actuating the slide and on the other hand the control contour and the control cam, and / or wherein the actuating lever on the one hand with the slide and on the other hand with the control contour and Control cam is coupled.

If necessary, it is provided that the control contour and the control cam are designed such that when the actuating mechanism and in particular the actuating lever are actuated uniformly, that is to say when the actuation lever moves uniformly

Control contour or the control cam starting from the closed position, the end of the bracket of the bracket first moves away from the punch opening, then to

Punch opening is moved, and then moved away from the punch opening.

The device according to the invention is characterized in particular by the fact that the holding brackets can be opened and closed and objects can be provided with holes by actuating an actuating lever. As with conventional filing systems, the actuating lever is preferably pivoted in order to open and close the holding bracket. This function corresponds essentially to the function that exists with any conventional filing mechanism. In addition, the following function is also effected with this movement of the actuating lever.

In an intermediate step, in particular before the holding brackets are opened, the punch ends of the pins of the holding brackets are briefly removed from the base and thus from the punching openings. This will release a hole in the hole

Item can be introduced.

The punching openings are preferably provided in the punching plate in all embodiments and serve as counter cutting edges for the punching ends. The stamping plate preferably covers the slide from above. In all embodiments, a cover can be provided above the stamping plate and therefore also above the slide. The cover is preferably arranged at a distance from the stamping plate, so that a gap is kept free between the cover and the stamping plate. This gap is used to hold the object to be punched. The cover preferably comprises a through opening arranged transversely to its course for each pin or for each punching end. According to one embodiment, the pins protrude into the through openings in each position, even in the open hole position

Cover. The cover is preferably rigidly connected to the base. The pins are guided or held relative to the base via the through openings. For exact positioning of the object, the device can have a stop which limits the gap on one side.

Alternatively, the kinematics can also be selected so that the punch ends in the open hole position from the punch plate and from one if necessary

provided cover are pulled so that a sheet that is being punched can remain on the bracket to be stapled. If necessary, the cover can also be omitted in this embodiment, so that only a punching plate is provided, from which the punching ends are drawn in the open hole position. This hole gap is preferably kept minimal, so that for example, only one to five sheets can be pushed through. In this embodiment, the connection of the pin to the respective stirrup is to be designed such that insertion of the punch ends into the punch openings is made possible. For example, the snap lock or the bond between the pins and the brackets can be achieved via a metal mandrel that is stable and in

Establishes essentially play-free connection between the bracket and the respective pin.

A flattened elevation can be provided on the cover or in the area of the base so that those leaves that are in the open position for arrangement, in particular on the left side, cannot slip out of the gap. This elevation is particularly appropriate in front of the punch holes.

In this embodiment, the device is preferably arranged in a folder cover in such a way that the pins are closer to the folder back than the remaining parts of the holding bracket. This allows the sheets to be inserted and punched into the hole from the left. The holding bracket can be opened, for example, in the middle, that is to say at the highest point of the holding bracket, or laterally offset.

In this embodiment, the holding brackets are pivotally connected to the base, the mounting or the connection of the holding brackets preferably being further away from the file back than the pins. In this embodiment, the basic mechanics of the pivoting of the brackets is thus compared to a conventional one

Embodiment rotated by 180 °.

Such an arrangement of the device on a folder cover or on a folder can be provided in all embodiments, with these

Embodiments then the pins are arranged closer to the back of the folder cover or the folder than those areas in which the bracket is pivotally connected to the base.

This results in two alternative embodiments for the kinematics. On the one hand, the punch ends can be made from the cover or from the open hole position Punching plate must be pulled. On the other hand, the punch ends can be made from the

Punching plate, but not pulled out of the cover, so that they are held or guided laterally by the cover even in their open hole position.

In all embodiments, it is preferably provided that all of the holding brackets,

in particular, all of the brackets together with their pins can be actuated by a single actuating lever and in particular also a single slider.

By simply moving the lever further, the punch ends of the pins are reinserted into the punch openings or into the base, as a result of which the inserted object is perforated.

The function of opening the retaining bracket is then effected by moving the actuating lever further. For this purpose, two functions are required by the actuation mechanism and in particular by the actuation lever. On the one hand, the holding brackets have to be moved so that a punch gap is first opened, then punched, then the holding brackets are opened.

In order to do this, the pins of the bracket must remain connected to the bracket in certain phases of this movement and to the base in other phases. This is done using the slider. This slide is also actuated by the actuating mechanism or its actuating lever.

The snap closure can each comprise a mandrel and an opening, for example. The mandrel is provided for example at the insertion end of the pin and the opening at the end of the bracket. By bringing these two components together, the mandrel is inserted into the opening. The mandrel can have an undercut or a groove in which an elastically deformable element of the opening engages. By overcoming the holding force, these two components can be separated. As an alternative or in addition, one of the two components can also be magnetic, so that the mounting takes place via magnetic forces. In any case, it is advantageous if a mandrel is inserted into an opening, so that there is also a positive coupling on the side of the insertion end of the pin to the end of the bracket.

The invention is further described below using an exemplary, schematically illustrated embodiment, wherein

2 show different views of the device in the open hole position,

3 different views of the device in or after the

show closed hole production, and

4 show different views of the device in the open insertion position.

Unless otherwise stated, the reference symbols in the figures correspond to the following components:

 Base 1, folding bracket 2, pin 3, bracket 4, punching end 5, punching opening 6, insertion end 7, insertion opening 8, actuating mechanism 9, main extension direction 10, end (of the bracket) 11, punch gap 12, retaining groove 13, slide 14, retaining contour 15, first

Holding extension 16, release opening 17, second holding extension 18, snap lock 19, control contour 20, control cam 21, actuating lever 22, slide lever 23, punch plate 24, cover 25, stop 26.

A punching plate 24 and a cover 25 are provided in all the embodiments of FIGS. 1 to 4, but these elements are partially hidden in the figures in order to be able to also describe the parts underneath, such as the slide 14.

Figures 1a, 1b and 1c show an embodiment of a device according to the invention in three different views.

The device comprises a base 1 to which two holding brackets 2 are fastened. The bracket 2 are each formed in several parts and include a pin 3 and one Bracket 4. The pins 3 each include a punching end 5 and an insertion end 7. The punching end 5 acts in all embodiments as a punch or is designed as a punch. In addition, an actuating mechanism 9 is provided, by the

Actuation the device can be brought into different positions.

The device further comprises a slide 14, which in this view is partially covered by the punch plate 24. The slide 14 can along a

Main extension direction 10 is moved and in particular moved back and forth. The bracket 4 includes an end 11 which in the present position with the

Insert end 7 of pin 3 is in contact. In particular, the insertion end 7 and the end 11 of the bracket 4 are aligned with one another. In addition, the punch 3 is attached to the base 1 with its punching end 5. As a result, the device is in its closed position.

The actuating mechanism 9 comprises an actuating lever 22

Operating lever 22, the operating mechanism 9 can be operated, in particular operated manually. The lever acts on the one hand via a control cam 21

Control contour 20. The two brackets 4 can be pivoted through these two elements. In addition, the actuating lever 22 actuates, in particular via a

Slider lever 23, also the slider 14. The brackets are preferred in all

Embodiments are pivotally coupled to the base in a conventional manner as shown in Fig. 1c.

With this configuration, the slide 14 and the bracket 4 can be moved when the actuating lever 22 is actuated. In the present form they are

Retaining bracket 2 closed and the slide 14 is in a position in which the punch ends 5 of the pins 3 are held on the base 1. In addition, the control cam 21 is arranged on the control contour 20 such that the bracket 4 against the

Insert ends 7 of the pins 3 are pressed.

Figures 2a, 2b and 2c show different views of the device in the open hole position. The components shown correspond to the components shown in FIG. 1. The actuating lever 22 is pivoted upwards from the position of FIGS. 1, whereby the actuating mechanism 9 is actuated. On the one hand, the control cam 21 is hereby positioned on the control contour 20 in such a way that the stirrups 4 are moved away from the punch opening 6 and the punch ends 5 of the pins 3 are pulled out of the punch openings 6. This is made possible in particular by the fact that the actuation of the actuation lever 22 also moves the slide 14 away from its original position.

The slide 14 comprises a holding contour 15 for each pin 3. The holding contour 15 extends along the main direction of extent 10 and comprises, in succession, a first holding extension 16, a release opening 17 and a second holding extension 18. The punching end 5 of the pin 3 comprises a holding groove 13 which along the

Main direction 10 extends.

In the present position, the slide 14 is positioned such that the punching end 5 is arranged in the area of the release opening 17 of the holding contour 15, which makes it possible to remove the pins 3 from the punching opening 6. In particular, the first holding extension 16 is pulled out of the holding groove 13 of the pin 3. At the same time, the insertion end 7 of the pin 3 is connected to the end 11 of the bracket 4.

The connection between the insertion end 7 of the pin 3 with the end 11 of the bracket 4 is designed, for example, as a snap lock 19 which engages when the insertion end 7 is pressed onto the end 11 of the bracket 4. Only by overcoming a certain holding force can the two ends 7, 11 be separated from each other again. However, if the pin 3 is not held on the base 1, this connection remains upright when the brackets 4 move and the pin 3 is pulled out of the base 1. As a result, a punch gap 12 is kept free, in which an object, such as a paper sheet or the like, can be inserted.

The punching openings 6 are preferably provided in the punching plate 24 in all embodiments and serve as counter cutting edges for the punching ends 5. In all

Embodiments can, as shown in Fig. 2c, above the punch plate 24 and therefore a cover 25 may also be provided above the slide 14. The cover 25 is arranged at a distance from the stamping plate 24, so that a gap is kept free between the cover 25 and the stamping plate 24. This gap is used to hold the object to be punched. For exact positioning of the

The device has a stop 26 which limits the gap on one side.

In the open hole production, the punch ends 5 of the pins 3 are as far from the

Punch openings 6 drawn that an object can be inserted into the gap as far as it will go. However, the punch ends 5 are not from the

Cover 25 pulled so that the punch ends 5 are held or guided laterally through an opening provided in the cover 25.

If, as shown in FIGS. 3a, 3b and 3c, the actuating lever 22 is moved further, the control cam 21 on the control contour 20 is also moved further. The control contour 20 is designed in such a way that with a uniform

Movement of the actuating lever 22 causes a back and forth movement of the bracket 4. For this purpose, the control contour 20 is S-shaped in the present embodiment.

In addition, the control cam 21 is moved along a circular path or along a curve, so that the stirrups 4 after the pins 3 have been pulled out of the base 1 to form the punch gap 12 in the present position of FIGS. 3 again in the base 1 and in particular in the Punch opening 6 are introduced.

In Fig. 3a, the top cover and thus also the punch openings 6 is not shown in order to better recognize the shape and the contour of the slide 14.

In Fig. 3b, the cover including punch openings 6 is shown. In the present position, the punched ends 5 of the pins 3 are inserted into the punched openings 6, with which holes have already been punched out into the object to be punched. In the present position, the actuating lever 22 is already moved so far that the punch ends 5 of the pins 3 are held on the base 1 by the second holding extension 18 of the holding contour 15 of the slide 14. For this purpose, the second holding extension 18 projects into the holding groove 13 of the pin 3. The slide 14 is actuated again by actuating the actuating lever 22.

In the representations of FIGS. 3a, 3b and 3c, the device is in or after the hole has been closed.

If the actuating lever 22 is now moved further, as shown in FIGS. 4a, 4b and 4c, the brackets 4 are also moved further away from the punch openings 6. After the holding force of the snap locks 19 has been overcome, the ends 11 of the brackets 4 thus separate from the insertion ends 7 of the pins 3. The pins 3 are held on the base 1 with their punch ends 5. In this open insert position it is possible to insert perforated sheets and file them. For this purpose, the insertion opening 8

kept clear. If the sheet or the object is inserted, the

Operating lever 22 can be moved back to its lower starting position (as in Fig. 1).
