Description

Electrically powered stapling device

The invention preferably relates to a mobile portable stapler for driving fasteners, such as staples, into an object, comprising housing means having a main body portion and a handle portion extending away from the main body portion, wherein ejection means are disposed in the main body portion by means of, respectively a fastener is accelerated to eject the fastener from an outlet opening of the stapler, a magazine device, for receiving a supply of fasteners on the stapler, a drive device for the ejection device, which comprises an electric motor and a power supply means, in particular as energy storage means, such as a rechargeable electric accumulator is formed, which is electrically connectable or connected to the electric motor, at least one triggering means with a actuatable trigger, by the actuation of which at least one fastening means can be accelerated by means of the ejection device actuated thereby and ejected out of the outlet opening, wherein the actuatable trigger is arranged in the region of the handle portion of the housing;

Portable stapling devices that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps and the like and to drive these fasteners into articles are well known. Such fastener drive tools are used for example in the manufacture of furniture for applying coatings, such as leather covers, to furniture or for producing a bottom or a lid closure of cardboard. Depending on the field of application, staplers may differ from each other in their basic structural design. However, such pneumatic staplers usually always have a piston in a cylinder between an upper and a lower dead center

CONFIRMATION COPY is movable. A fastener drive element is disposed within the line of movement of the piston and serves to contact and eject the fasteners which are inserted into the fastener drive track by a magazine assembly. There are known such pneumatic fastener driving tools for nails provided with means for switching between two modes, wherein in one mode each activation of the trigger results in a single shot of one fastener and in the other mode each activation of the trigger results in a plurality of successive shots, as long as the trigger is activated and / or a mechanical contact of a microswitch in the region of a footprint of the tack nail device detects contact with a pad.

There are also known portable stapling devices, which are additionally provided with forceps elements with which legs of staples are bent after their entry into a cardboard. Such stapling devices are mainly used for the production of closures on cardboard, in particular for the closure of the lid wings of the cardboard. In this type of stapler it is necessary to coordinate the ejection movement with the movement of the forceps elements in order to grasp the ejected two-legged clamps with the forceps elements when they have already penetrated into the cardboard and the two legs of the respective clamp towards one Turn base of the clip. Such a portable portable stapler is known, for example, from EP 2 679 344 A2. The paperboard stapler from EP 2 679 344 A2, in contrast to most other binders currently on the market, is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a DC electric motor fed by a rechargeable battery and integrated in the mobile portable stapler. The electric motor and its accumulator are housed in a housing part of the stapler, which is located between the handle of the stapler and the magazine for staple stock, in close proximity to the magazine. This stapler can not be satisfied that the magazine can not be easily operated due to the housing part of the motor. In particular, locks the housing part of the engine in the Operation of the stapler a clear view of the magazine, for example, for optical control of the remaining amount of staples in the magazine.

The invention is therefore based on the object to improve an industrially or commercially usable stapling device of the type mentioned in that the storage device user-friendly controllable and better accessible.

This object is achieved in a stapler of the type mentioned in the present invention that the electric motor according to the invention is now arranged in the handle portion and its axis of rotation with a longitudinal axis of an acceleration path of the expeller runs non-parallel. According to the invention, it is thus provided that a better accessibility of the magazine can not be achieved by arranging the magazine at a different location or by structurally redesigning it. Surprisingly, the accessibility of the magazine device can be improved in a significant way, that the electric motor is not only arranged at a greater distance than before to the magazine device. By integrating the electric motor in the handle portion of the housing, the motor can be housed in a housing part, which must be present for reasons other than the inclusion of the engine anyway. It can thus a separate, conditional only by the engine, housing portion of the stapler and its weight avoided and the handle additionally be supplied to other than its actual intended use. The measure according to the invention also surprisingly leads to an ergonomic improvement, since the weight of the engine and possibly a transmission, including the articulation or connection of the drive to an expulsion or outlet mechanism, is arranged in the handle or at least close to the handle. The weight resulting from the engine and from the other components of the engine associated with the engine thus produces no, or at most only a slight, torque around the point at which the operator holds and handles the stapler during its operation. The operator has to thus spend less force to handle the stapler and fatigued so less quickly. In a preferred embodiment of the invention, at least a portion of the motor, preferably the entire motor, may be located directly in and / or below the portion of the handle portion with which the operator grips with his hand grasping the handle portion and thereby holding the stapler.

The advantages mentioned can be increased even further when a motor downstream of the transmission, in particular for speed reduction and torque increase, in particular a planetary gear, likewise in the handle portion - or at least in its immediate vicinity or in the range of this - the housing is arranged.

Preferably, the power supply means is formed as a replaceable electrical accumulator, which is insertable in a, at one end of the handle portion of the housing, receiving the mobile portable stapler and can be removed therefrom. Due to this location of the arrangement of the accumulator, only a small torque is required for handling the stapling device, at least because of the accumulator, whereby handling of the stapling device is made possible with only little effort. In an advantageous further embodiment of the inventive stapling device can be provided in a provided on the handle portion of the housing arrangement of the accumulator that at least one, preferably all required, electrical supply line from the accumulator to the motor is arranged exclusively in the handle.

In a preferred embodiment of the invention, the arranged in the handle portion of the housing electric motor may be formed as a brushless DC motor. The lack of wear-prone brushes in the engine not only leads to a longer service life and maintenance of the engine, the missing brushes also lead to a smaller size of the motor and thus to a way the handle section alone ergonomic and not to be interpreted as meaning that the motor can be accommodated in the handle. The aspect of using a brushless DC motor as a drive for a portable, mobile stapling device for industrial use in the field of production and packaging, with which staples are ejected, can also be independent of other aspects of the present invention, in particular - but not exclusively - independent meaning in connection with a stapling device according to the preamble of claim 1. For an ergonomic design of the stapling device may also contribute a preferred measure, which provides that the axis of rotation of the electric motor with respect to an acceleration path of the expeller for driving out a staple , an angle is selected from a range of 60 ° to 120 °, preferably at an angle of at least approximately 90 °. Although it is further preferred that the two axes intersect. However, it can also be provided that the two axes are spatially offset from each other. In this case, the said angle between the two axes results by projecting the one axis in the direction of the other of the two axes. It has also been shown to be favorable when the power supply means in the region of one end of the handle, preferably at the free end of the handle, is arranged. If, in a particularly preferred embodiment of the invention, an exchangeable accumulator which can be arranged on the stapling device by means of a quick connection, for example a latching or snap connection, can be provided for such accumulators at the free end of the handle section of the housing. An electrical contact between the receptacle and the accumulator can be achieved by means of contact elements integrated in the receptacle. This results in a particularly short wiring between the power supply means and the electric motor. This facilitates both the installation of the stapler and possible repairs. A short wiring also leads to a low electrical resistance of the wiring, which reduces electrical losses and the Increases the amount of energy in the accumulator that can be used for stapling. In addition, the weight of a battery at the free end of the handle portion results in a better balance of the stapler. The weight of the accumulator also acts as a counterweight to the mechanics of the expulsion or ejection device of the stapler.

According to a further aspect of the invention, in a mobile portable stapling device according to the preamble of claim 8, which is provided for driving in staples, in particular substantially U-shaped brackets, in an object, also the object to be solved, the filling of the magazine simplify. This object can be achieved by a level indicator or a level signal means, which is provided for signaling a staple supply contained in the magazine. Since this is always recognizable or perceptible for a user, whether an emptying of the magazine is imminent, an unanticipated vacancy of the magazine can be avoided. As a means for outputting an acoustic signal representing a certain level

Staples for filling a magazine are usually offered as staple blocks that contain a certain number of brackets glued together. These staple blocks thus have a certain length depending on the number of staples and the size of the brackets. In a preferred embodiment of the invention, a marking can be provided on the magazine in addition to the level indicator, which at least approximately the length of the staple blocks suitable for the stapler. As soon as the level indicator reaches the mark, there is sufficient space in the magazine so that a new clip block can be filled into the Magezin again. Depending on the length of the magazine and the length of the staple blocks can be provided that the mark, as seen from the magazine end, is approximately at the level of an integer multiple of the length of a staple block. If the marking is reached by the level indicator, this indicates visually perceptible that a number of staple blocks can be filled in the magazine, which corresponds to the integer multiple (N = 1, 2, 3 etc). The The level indicator and the marking thus make it easier for the magazine to be completely refilled, if at all possible, in the event of a supply of staples in the magazine which is likely to end. As a result, the working cycles between two refilling operations can be designed as long as possible, whereby the number of unproductive refilling operations can be reduced to a minimum.

The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device having a main housing portion and a handle portion extending away from the main housing portion, wherein in the main housing portion an ejection means is arranged, by means of each of which a fastening means can be accelerated ejecting the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, a drive device for the ejection device, which is connectable or connected to a power supply means, at least one triggering means of a triggering device with an actuatable trigger, by its operation at least one fastening means can be accelerated by means of the ejection device set in motion thereby and can be ejected from the outlet opening

Portable stapling devices that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps and the like and to drive these fasteners into articles are well known. Such fastener drive tools are used for example in the manufacture of furniture for applying coatings, such as leather covers, to furniture or for producing a bottom or a lid closure of cardboard. Depending on the field of application, staplers may differ from each other in their basic structural design. However, such pneumatic staplers usually always have a piston which is movable in a cylinder between an upper and a lower dead center. A fastener drive element is disposed within the line of movement of the piston and serves for contacting and ejecting the fasteners that are inserted from a magazine assembly in the fastener drive track. Nails pneumatic fastener driving tools are known which are provided with means for switching between two modes, wherein in one mode each activation of the trigger results in a single shot of one fastener and in the other mode each activation of the trigger results in a plurality of consecutive Shots as long as the trigger is activated and / or a mechanical contact of a microswitch detected in the region of a footprint of the tack nail device contact with a pad.

There are also known portable stapling devices, which are additionally provided with forceps elements with which legs of staples are bent after their entry into a cardboard. Such stapling devices are mainly used for the production of closures on cardboard, in particular for the closure of the lid wings of the cardboard. In this type of stapler it is necessary to coordinate the ejection movement with the movement of the forceps elements in order to grasp the ejected two-legged clamp with the forceps elements when they have already penetrated into the carton and the two legs of the respective clamp towards a base leg to bend over the bracket. Such a portable portable stapler is known, for example, from EP 2 679 344 A2. The paperboard stapler from EP 2 679 344 A2, in contrast to most other binders currently on the market, is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a DC electric motor fed by a rechargeable battery and integrated in the mobile portable stapler. The electric motor and its accumulator are housed in a housing part of the stapler, which is located between the handle of the stapler and the magazine for staple stock, in close proximity to the magazine. In this and other staplers can be considered disadvantageous that the brackets can not be set precisely to target positions of objects. The invention is therefore an object of the invention to provide a stapling device of the type mentioned above, which has precise properties with respect to the possibilities of setting brackets precisely at predetermined positions. This object is achieved in a stapling device of the type mentioned according to the invention by at least one disposed in the housing means light emitting means, which is arranged such that its emitted light contains an optically perceptible position information to be ejected from the stapler U-shaped brackets. The invention thus essentially proposes to convey by means of light to the user at least information about a position at which a staple, in particular a substantially U-shaped staple, can be ejected with the stapling device on account of its instantaneous spatial orientation. With this knowledge, a user can align a stapling device according to the invention better than heretofore in such a way that with a stapling operation, a staple can also be introduced into an object at the designated position intended for this purpose.

In a preferred embodiment of the invention, at least one light emitting means can be provided with which a directed light beam can be emitted from the housing in the direction of an object. With a directional light beam, positional information can be displayed and conveyed with particular precision. Light emitting means emitting directional light beams may be, for example, lasers. In another preferred embodiment of the invention, the light beam may include optically detectable position information about a plane in which a clip plane of ejectable clips passes. In this context, a clip plane may in particular be understood as meaning a plane of symmetry of the U-shaped clips which runs centrally through the base leg and parallel to the two side legs of the clips. Such information may be particularly, but not exclusively, an advantage in connection with paperboard processing where two hinged top flaps are for formation a closure of the cardboard to be connected by means of one or more brackets. With such a light beam, the light beam of the stapler can be aligned on a joint between the two lid wings, whereby an arrangement of the stapling device is ensured in a desired position in which in each of the two lid wings one leg of each clip is set.

An alternative or supplementary measure can provide in a further preferred embodiment of the invention that the at least one light emitting means is arranged in the housing device and contains position information about a plane in which a clamping plane extends from ejectable clamps. Also by knowing the clip plane, ie the plane within which the staple to be ejected as well as the ejection channel of the stapler is located, can also contribute to the precise placement of staples in objects. In this case, it is particularly advantageous if both the center plane and the clip plane can be displayed by means of light emitting means of the stapling device.

A further aspect of the invention, which may also have significance irrespective of other aspects of the invention, provides a plurality of different light emitting means with which light can be emitted in different colors, or provides the at least one light emitting means with which light in different colors can be emitted With the different colors in addition to the position information and status information to the stapler are visually perceptible displayed. Thus, for example, the one or more light emitting means, besides the position information on the Ausstossebene the brackets or other position information, with different colors for this respective position information also signal whether the stapler is ready for ejection of a clip. This information may be particularly important if - as is provided in preferred embodiments of the invention - for a discharge release at least one particular condition must be met. For example, in preferred embodiments of the invention, this may be the detection of the presence of a user's finger on the trigger and / or the presence of an object in the area of the footprint, which is the outlet opening for ejecting staples, or the contact of the footprint of the stapling device with an object. In a preferred embodiment of the invention, the stapling device has only one light emitting means, which transmits a forwardly directed light beam from the device. The light beam should in this case run in a plane which runs at least substantially perpendicular to the base leg of the respectively ejected staple, preferably centrally through the base leg. This preferred orientation of the light beam may also be defined as lying in a plane at least substantially perpendicular to the plane of the clip, which span the three legs of the respective undeformed clip to be ejected. This plane preferably runs parallel to the two free (still undeformed) legs and has the same distance to each of these. This light beam may preferably be at least one laser light beam. In addition to a point laser, line lasers are of particular interest in this context, whose emitted light appears as a line on an object. The light beam is in this case a light plane emitted by the line laser. Such lasers are already known per se and are offered by various manufacturers. In other embodiments, other light sources are conceivable for this light beam, for example one or more LEDs.

In a further preferred embodiment of the invention, the stapling device only has at least one light emitting means which displays the staple plane formed by the three legs of the respective staple (still undeformed) to be ejected. The at least one light emitting means is preferably and preferably illuminates in this clip plane and / or emits one or more light beams located in the clip plane. Preferably, such a light emitting means is provided laterally on the housing on both sides of the outlet opening of the clamps. These light emitting means may preferably be LEDs. In other embodiments are for this At least one Lichtemittiermittel other light sources conceivable, for example, one or more lasers.

In a particularly preferred embodiment of the invention, the stapling device has both light emitting means, namely at least one for signaling the position of the clip center and at least one, preferably at least two, light emitting means, which (s) indicate the position of the clip plane visually perceptible. In a further advantageous embodiment of the invention, which may independently of other features and in connection with the features of the preamble of claim 1 have independent significance for generic stapling devices and thus represents a separate invention, at least one laser can be provided as Lichtemittiermittel, wherein Adjusting means are provided for the light emitting means with which a direction (emission direction) of the directional emitted light of the light emitting means can be adjusted and changed. Since the most precise position information to be imparted with the aligned light beam of the light emitting means, it is necessary that the laser is mounted as accurately as possible in its intended orientation and position in the stapler. Due to manufacturing and / or assembly inaccuracies, however, there is the danger that the laser, in particular a line laser, does not assume exactly the intended orientation and / or position in the holder. By means of the adjustment described here, such inaccuracies can be corrected and the laser can be aligned as desired. In the case of a line laser, in particular the course of the line imaged by the laser light on an object can be changed and set. In other embodiments of the invention, the described measure may also be provided in the case of light emitting means other than lasers, for example an LED as light emitting means.

In a preferred embodiment of the stapling device according to the invention, a commercially available laser, in particular a line laser, can be provided, which in one Housing is arranged. The housing of the laser should be provided with a circular cross-section outer surface and be arranged in a holder in which the housing is rotatable. Preferably, an engagement element is provided on the housing, by the actuation of the housing is rotatable in its holder. By rotation, the laser may then undergo a different orientation and thus at least partially correct a misalignment. Preferably, the engagement member may be accessible for actuation not only during assembly of the stapler but also on the finished assembled and ready-to-use stapler. This makes it possible to make a correction also later and without disassembly of the stapler.

In an advantageous development of this possible embodiment of the invention, the engagement element may at least partially surround the outer surface and be accessible through a recess of the holder for manual actuation. In a further possible concretization, the engagement element can be elastically compressible and arranged in the preferably slot-shaped recess, at least slightly clamped. Such an engagement element may for example be an O-ring, which is arranged under tension on the housing. The tension should be such that in an attempt to rotate the O-ring, no relative movement between the O-ring and the housing takes place, but the housing is taken with the movement of the O-ring. By the at least slight clamping can be ensured that the Lichtemittiermittel can not move unintentionally in its holder. For a change in its orientation or position an intended operation is required. In this way, the O-ring can be manually actuated through the recess to a rotational movement, through which the housing of the Lichtemittiermittels taken and undergoes a change in its orientation or orientation. Due to the slight clamping effect, with which the elastically deformable O-ring is arranged in the recess of the holder, the rotation takes place against an at least slight frictional force, which makes it possible for the light emitting means to be rotatable and thus adjustable by very small angles of rotation. Yet another aspect of the invention, which may also be meaningful as an independent invention independently of other aspects of the invention, may provide that the at least one triggering means comprises a detection means for detecting a body part arranged on the trigger, in particular a finger. The detection means for detecting a body part arranged on the trigger can in this case preferably be arranged in the actuatable trigger or on the housing, directly next to the actuatable trigger. With such a sensor on the trigger means an additional safety measure can be realized that only a staple is ejected when an operator contact with the triggering means or at least a body part, such as a finger is in the vicinity of the triggering means. This safety measure may be provided either alone or as a required condition in addition to other conditions. A suitable detection means for this purpose may be, for example, a proximity sensor, a photodiode or a photoresistor.

Another condition for performing a stapling operation may be detection of the presence of an object. For this purpose, at least one detection means for detecting the presence of an object below the footprint can be provided in the region of the footprint of the stapling device.

In a preferred embodiment of the invention, means may thus also be provided with which a detection signal of the detection means can be fed to a control of the stapling device, wherein the control is set up such that the detection signal is a prerequisite for releasing an ejection of a staple.

Finally, it has also proved to be particularly advantageous if the detection signal of an existing body part can be used to switch on the at least one light emitting means. Thus, this can be at least one Lichtemittiermittel be turned on only if a user also provides the use of the stapler.

According to a further aspect of the invention, at least one of the measures described above according to the invention can also be provided in a mobile strapping device for strapping packaged goods with a plastic or a metal strip with which a loop of such a strip is tensioned and subsequently a closure of the strapped loop Belt loop can be attached. In particular, at least one Lichtemittiermittel may be provided on the housing of such Umfreifungsvorrichtung, which indicates the Umreifungsgerät an insertion position and / or an end position of a Umreifungsbands in the strapping. Here, too, the light emitting means can be arranged on the housing device of the strapping device in such a way that its emitted light represents optically perceptible position information with which the operator is instructed to arrange the strap in a set position provided in the strapping device.

The security against an unwanted release of the stapling device can be further increased by a further preferred embodiment of the invention, in which the trigger against the spring forces of at least two spring elements is actuated. It can be provided in an advantageous manner that when actuated, the trigger is initially operated only against the spring force of the first spring and only in the course of further actuation of the trigger against the spring forces of both spring elements. The triggering of an ejection is preferably carried out after the spring force of the second spring element acts against the actuation of the trigger on the trigger. Preferably, therefore, both spring elements are in the path of movement of the trigger, but act at different already covered actuation paths of the trigger, for the first time on the respective trigger. Due to the sudden increase in spring force due to the additional action of the second spring element, the information can be conveyed to the user that now triggering a Expulsion is imminent. A user can thus better coordinate the output of a bracket.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings.

The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device having a main housing portion and a handle portion extending away from the main housing portion, wherein in the main housing portion an ejection means is arranged, by means of each of which a fastening means can be accelerated ejecting the fastening means from an outlet opening of the stapling device, a magazine device, for receiving a supply of staples as fastening means on the stapling device, a drive device for the ejection device, which is connectable or connected to a power supply means, a clinching device, with which two legs of one from a Outlet opening of the stapler exiting clip are umbiegbar, at least one triggering means of a triggering device with an actuatable trigger, by the actuation of at least one Befestigu Fuel can be accelerated by means of the thus set in operation Ausstosseinrichtung and ejected from the outlet opening.

Portable stapling devices that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps and the like and to drive these fasteners into articles are well known. Such fastener drive tools are used for example in the manufacture of furniture for applying coatings, such as leather covers, to furniture or for producing a bottom or a lid closure of cardboard. Depending on the field of application, staplers may differ from each other in their basic structural design. However, such pneumatic staplers usually always have a piston in a cylinder between an upper and a lower dead center is movable. A fastener drive element is disposed within the line of movement of the piston and serves to contact and eject the fasteners which are inserted into the fastener drive track by a magazine assembly. Nails pneumatic fastener driving tools are known which are provided with means for switching between two modes, wherein in one mode each activation of the trigger results in a single shot of one fastener and in the other mode each activation of the trigger results in a plurality of consecutive Shots as long as the trigger is activated and / or a mechanical contact of a microswitch detected in the region of a footprint of the tack nail device contact with a pad.

There are also known portable stapling devices, which are additionally provided with forceps elements with which legs of staples are bent after their entry into a cardboard. Such stapling devices are mainly used for the production of closures on cardboard, in particular for the closure of the lid wings of the cardboard. In this type of stapler, it is necessary to coordinate the ejection movement with the movement of the forceps elements to grasp the ejected two-legged clamps with the forceps elements when they have already penetrated into the carton and the two legs of the respective clamp towards a base leg to bend over the bracket. Such a portable portable stapler is known, for example, from EP 2 679 344 A2. The paperboard stapler from EP 2 679 344 A2, in contrast to most other binders currently on the market, is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a DC electric motor fed by a rechargeable battery and integrated in the mobile portable stapler. The electric motor and its accumulator are housed in a housing part of the stapler, which is located between the handle of the stapler and the magazine for staple stock, in close proximity to the magazine. In this prior art stapler can be considered as potentially disadvantageous that an actuation of the shutter only after a discontinuation of the device on an object and thus only a relatively slow work with this stapler is possible.

The invention is therefore an object of the invention to provide a stapling device of the type mentioned, with which the working speed when setting brackets can be increased. This object is achieved according to the invention in a stapling device of the generic type in that at least one detection means for detecting the presence of an object beneath the contact surface is provided in the region of the contact surface of the stapling device on which at least one clinching element of the clinching device for bending staples emerges from the contact surface during a stapling operation is. This detection means and the detection signal provided by him can be used to perform a stapling operation with a bracket even without subsequent actuation of the trigger. According to a second aspect of the invention, in a generic stapling device, the object is also achieved in that means of the triggering device are provided, with which at least two different operating modes of the stapling device are adjustable, wherein in the first operating mode by a (one-time) actuation of the triggering means / trigger only a stapling operation is triggered, in which only one staple is ejected and the legs are umbiegbar means of the clinching device, and in a second operating mode with an actuation of the triggering means a plurality of consecutive stapling operations are triggered, in each of which a staple ejected and their legs by means of the clinching device are bendable. As an alternative to the mentioned second operating mode or additionally as a third operating mode, in a preferred embodiment of the invention, such a mode can also be provided, in which a predetermined or variable determinable interval is used Fully automatic stapling operations are performed. An ejection of brackets in this latter mode of operation, for example, as long as or in each case take place, as after a first ejection a certain release condition for further automatic ejection of this automatic ejection series is given. One possible condition may be, for example, that the stapling device is not lifted off the object but is pulled or guided for automatic ejection of a series of staples via the respective object with constant contact with the object. Thus, it can be provided that the control of the stapling device stops a series of automatically occurring staple ejections as soon as the stapling device is lifted off the object. However, as long as the presence of the stapling device is detected on an object, without this the stapling device is lifted from the respective object, however, the automatically taking out ejection series is continued. Among other things, for this detection process, the stapling device may be provided with a release means which detects whether such a release condition is met.

Alternatively, it can also be provided that only for the first ejection of such a series of ejections automatically taking place in an automatic mode, the presence of the stapling device on an object must be detected and all subsequent ejections then take place without such a detection.

With regard to the number and / or time intervals of the ejections then following the first ejection, these preferably take place in accordance with predetermined values stored in the control of the stapling device. For example, in terms of the number of clips that can be ejected in this mode, a maximum of ejectable clips may be specified. Here too, the working speed can be significantly increased. Thus, for example, for introducing a series of staples into an object, it is possible to simply pull the stapling device placed on an object over the object in automatic mode and the staples are then expelled and driven into the object at a predetermined or predeterminable time interval. In order for each user to adapt the stapling device to his speed of work and his way of working, can in Another preferred embodiment of the invention for the automatic mode and a teach-in mode be possible. In this takes over and stores the stapling device, the time intervals in which a user manually successively the respective trigger means or the trigger twice or more often operated in succession. In the said preferred possible embodiment of the automatic mode, brackets are then ejected at precisely these time intervals.

With the measure provided for in accordance with the invention, stapling devices which are provided with a clinching device can be used for a faster operation, respectively. a more pleasant and less tiring way of working can be achieved.

It can thus be realized for stapling devices, which are provided with a clinching device, in addition, a semi-automatic mode for performing a plurality of consecutively executed individual stitching operations. In this operating mode of the semiautomatic sequence of several consecutively executed stapling operations, preferably provided as a second operating mode, a plurality of consecutively executed stapling operations, including clinching operations taking place in each case, can be made possible, wherein no manual operation is possible for each of these stapling operations Actuation of a trigger element by the operator is required. It must be made only a single actuation of the trigger element. In contrast to the automatic mode, it can be provided in the semiautomatic mode for triggering the staple ejections following the respective first staple ejection that they only take place if at least one other condition than in the automatic mode is met and means are provided with which or which can be detected the at least one condition for the semi-automatic mode is met. A possible condition may be, for example, that the stapler after a staple ejection must necessarily be lifted from the object to make the semiautomatic ejection of a series of brackets while still actuated trigger. It can thus be provided that the control of the stapler a series of semiautomatic clip ejections stops as soon as the stapler lifts off the object but does not return to the object when the shutter button is pressed. Among other things, for this purpose, the stapling device may be provided with a release means which detects whether such a release condition is met. The semi-automatic ejection of brackets can also be stopped by the fact that the operation, ie above all a pressing of the shutter is terminated.

In a preferred embodiment of the invention, in addition to the triggering means, a release means may be provided which, in at least one of the two operating modes upon satisfaction of a predetermined condition, provides a release signal for performing a stapling operation of the controller. In a particularly preferred embodiment of the invention, three possible operating modes are provided, namely a manual mode, a semi-automatic mode and an automatic mode, and in all three modes of operation, the release means can detect whether each next clip is released for ejection to release each clip to be ejected. Such a release agent can in particular contribute to increasing security, so that only when a security-relevant condition a stapling operation can be performed. The release means can thus comprise at least one detection means, with which a presence of an object in the area of the contact area, in particular a contact of the contact area with the object, can be detected. It can be provided that only with a detection of an object in the area of the footprint by means of a detection means a stapling operation can be released with a clamp. In this context, non-contact release agents are particularly preferred, that is to say in particular non-contact detection means which themselves do not require any mechanical contact for detecting the presence of an object in the area of the footprint.

However, the at least one detection means for detecting an object at the footprint, in particular a contact between the footprint and the respective object, can in principle be based on different detection principles. Thus, in particular optical detection means are possible, for example those having a light emitter and a light receiver, the object serving as a reflection surface of light emitted by the light emitter to be detected by the light emitter. Likewise, mechanically operating detection means are possible, for example microswitches. Further detection means may be, for example, light resistors, ultrasonic distance sensors, proximity sensors and other sensors which are able to fix the presence of an object.

A preferred development of the invention for this purpose can provide at least two detection means arranged at a distance from one another in the area of the contact area. For example, for non-planar, such as curved objects, it may be sufficient that a release for a stapling operation already takes place when one of the two detection means detects the presence of an object, in particular a contact with the object below this detection means and a corresponding signal provides control of the stapler.

In addition, in the same embodiment or in an alternative embodiment of the invention can also be provided that both of the at least two detection means must provide a release signal, so that a stapling operation can take place. If one or more clamps are driven into an object with a substantially planar surface in the area of the footprint and legs of the respective clamp are to be bent over, it can make a decisive contribution to increasing the reliability if both detection devices have a presence of an object in the region of the respective one to release a stitching operation Need to provide detection means. In this context, a particularly advantageous embodiment of the invention, when each of the two detection means a detection means is arranged on one of the two short side edges of the outlet opening. By such an embodiment it can be ensured that both legs - and not just one or no legs - penetrate a clip into the respective object. The at least one release means provided in addition to the actual release means, which is preferably designed as at least one detection means, has particular advantages in connection with the semi-automatic, preferably adjustable on the stapling device, as a possible operating mode. With this detection device can be ensured in a possible embodiment of the invention that each of the semiautomatic mode - after an initial initiation of a semi-automatic cycle of possible stapling operations - actually takes place stapling only when the footprint is actually on or at least directly above an object located. In addition, in the semi-automatic mode, the respectively determined detection result of an object present in the area of the contact area or a contact of the contact area with an object can be used to release and execute the respective one stitching operation. Preferably, it may be provided that for one, preferably for each, subsequent execution of a stapling operation in this cycle, first a non-presence of an object in the area of the footprint and then again a presence of an object in the area of the footprint must be detected.

In all conceivable embodiments of the present invention may be provided in a further preferred embodiment of the invention that an ejection of a clip takes place with a predetermined time delay after each given at least one condition for release of the ejection is met. In a particularly preferred embodiment, there may be two conditions, namely the detection of a body part on the trigger and the presence of an object below the outlet opening for the brackets. If both objects are detected, the release is made to eject a bracket. However, in this preferred embodiment, the emission is triggered and made with a time delay, for example from a range from -ms to-ms. The time delay may provide the advantage of greater security that the stapler is actually located on an object when a staple exits the staple outlet. In detection means, it may happen that this already when approaching a Object missed a contact that actually does not exist as given and thus an ejection of a clip occurs too early. By means of the described preferred measure, to provide a short delay for the ejection when the ejection conditions are reached, this behavior of detection means can be counteracted and the safety can be increased while still allowing a high working speed. Preferably, the length of the delay is adjustable on the stapler. Alternatively, it is also possible to provide a time-definite, unchangeable delay. The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device having a main housing portion and a handle portion extending away from the main housing portion, wherein in the main housing portion an ejection means is arranged, by means of each of which a fastening means can be accelerated ejecting the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, which is releasably fastened in the region of an ejection channel to a carrier part of the stapling device by means of a quick release, a drive device for the ejection device, which can be connected to a power supply means or is connected, at least one triggering means of a triggering device with an actuatable trigger, by the actuation thereof at least one fastening means by means of set in motion expulsion device accelerated and can be ejected from the outlet opening; Portable stapling devices that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps and the like and to drive these fasteners into articles are well known. Such fastener drive tools are used for example in the manufacture of furniture for applying coatings, such as leather covers, to furniture or for producing a bottom or a lid closure of cardboard. Depending on the field of application, staplers can differ from each other in their basic structural design differ. However, such pneumatic staplers usually always have a piston which is movable in a cylinder between an upper and a lower dead center. A fastener drive element is disposed within the line of movement of the piston and serves to contact and eject the fasteners which are inserted into the fastener drive track by a magazine assembly. Nails pneumatic fastener driving tools are known which are provided with means for switching between two modes, wherein in one mode each activation of the trigger results in a single shot of one fastener and in the other mode each activation of the trigger results in a plurality of consecutive Shots as long as the trigger is activated and detects a mechanical contact of a microswitch in the region of a footprint of the tack nail device contact with a pad. In the prior art can be seen as disadvantageous that display and controls are less user-friendly. The invention is therefore based on the object to improve the ease of use of the display and controls in a stapler of the type mentioned. This object is achieved according to the invention in a stapling device of the type mentioned by a display and operating device comprising a membrane keyboard, which controls as a membrane keyboard elements, by the operation settings of the stapler and / or state changes of the stapler are vornehmbar. The invention therefore proposes to provide, preferably, a central display and operating device on the stapling device, which comprises as many of the intended display and operating elements as possible and to form them as a membrane keyboard.

In a preferred embodiment of the inventive stapling device can be provided that the stapling device in a single ejection operating mode and in a semi-automatic operating mode in which after a single actuation of the trigger successively stapling operations are executable, is switchable, wherein the display and operating device has display means for signaling the activated operating mode. In an advantageous embodiment of the invention, the display and operating device may have at least one membrane keypad for setting the operating mode.

As an alternative to the said second operating mode or additionally as a third operating mode, in a preferred embodiment of the invention, a mode can also be provided in which further stapling operations are automatically carried out in a predetermined or changeable determinable interval, as long as the presence of the stapling device on an object is detected. Here too, the working speed can be significantly increased.

To increase the ergonomics and functional safety, it may be advantageous if a display means for signaling a fault condition of the stapler is provided on the membrane keyboard device. If the display and operating device has a display means for displaying a state of charge of a rechargeable battery of an electrically operated stapling device, it may be advantageous that the display device for the charging state, also a fault condition of the stapler is signaled, in particular by another display mode of the display means, in particular by a color change and / or by changing to a flashing mode.

In a further preferred embodiment of the invention, the stapling device may comprise at least one arranged in the housing means light emitting means which is arranged such that its emitted light contains optically perceptible position information to ejectable from the stapler U-shaped brackets. Preferably, this light emitting means can be switched to operation without emitting light. An actual switching on of the at least one light emitting means can preferably take place only after a further condition has been fulfilled, for example that an operator has arranged his hand or his finger at a specific position of the stapling device. It can thus For example, be provided on or near the trigger a detecting means for detecting the hand or a finger, for example, a proximity sensor. An operational readiness of the light emitting means, which leads to a switching on of the light emitting means without a further separate startup and the switching on of the light emitting means is dependent only on the fulfillment of at least one operating condition can be signaled by an arranged on the display and operating means display means of operational readiness. Such a display means may be, for example, a display means of the membrane keyboard device. It can also be a light-emitting diode.

An ergonomically favorable operating position, in which an operator also immediately notices warning or interference signals during operation of the stapling device and thus can perceive them, can be achieved by the display and operating device being mounted on a side surface of the skin housing section, in particular on an inclined side surface , is arranged.

The invention relates to a mobile portable stapling device for driving staples into an object, comprising a housing device having a main housing portion and a handle portion extending away from the main housing portion, wherein in the main housing portion an ejection means is arranged, by means of each of which a fastening means can be accelerated ejecting the fastening means from an outlet opening of the stapling device, a magazine device for receiving a supply of staples on the stapling device, which is releasably fastened in the region of an ejection channel to a carrier part of the stapling device by means of a quick release, a drive device for the ejection device, which can be connected to a power supply means or is connected, at least one triggering means of a triggering device with an actuatable trigger, by the actuation thereof at least one fastening means by means of set in motion expulsion device accelerated and can be ejected from the outlet opening. Portable stapling devices that use a fluid, particularly compressed air, to accelerate fasteners such as staples, nails, clamps and the like and to drive these fasteners into articles are well known. Such fastener drive tools are used for example in the manufacture of furniture for applying coatings, such as leather covers, to furniture or for producing a bottom or a lid closure of cardboard. Depending on the field of application, staplers may differ from each other in their basic structural design. However, such pneumatic staplers usually always have a piston which is movable in a cylinder between an upper and a lower dead center. A fastener drive element is disposed within the line of movement of the piston and serves to contact and eject the fasteners which are inserted into the fastener drive track by a magazine assembly.

There are also known portable stapling devices, which are additionally provided with forceps elements with which legs of staples are bent after their entry into a cardboard. Such stapling devices are mainly used for the production of closures on cardboard, in particular for the closure of the lid wings of the cardboard. In this type of stapling devices, it is necessary to coordinate the ejection movement with the movement of the forceps elements to grasp the ejected U-shaped two-legged brackets with the forceps elements when they have already penetrated the carton and the two legs of the respective brackets in the direction to bend over to a base of the bracket. Such a portable portable stapler is known, for example, from EP 2 679 344 A2. The paperboard stapler from EP 2 679 344 A2, in contrast to most other binders currently on the market, is driven electrically and not pneumatically. For this purpose, the stapler from EP 2 679 344 A2 has a DC electric motor fed by a rechargeable battery and integrated in the mobile portable stapler. The electric motor and its accumulator are housed in a housing part of the stapler, which is located between the handle of the stapler and the magazine for the staple stock, in immediate proximity to the magazine. This stapler can not be satisfied that the magazine can not be easily operated due to the housing part of the motor. In particular, the housing part of the motor obstructs a free view of the magazine when operating the stapler, for example for optical control of the remaining amount of staples in the magazine. In addition, clamps jammed in the discharge channel can only be removed from the discharge channel in a time-consuming manner.

The invention is therefore an object of the invention to improve an industrially or commercially usable stapling device of the type mentioned in that the cartridge device user-friendly removable and usable, in particular to remove jammed in the ejection channel brackets as quickly as possible and put the stapler back into operational readiness to be able to.

This object is achieved in a stapling device of the type mentioned in the present invention that the quick release is provided with guide means which successively in an insertion movement of the magazine on the support part the magazine in two different, mutually non-parallel, preferably at least substantially rectilinear, Directions leads. Preferably, the magazine can be removed even when removed from the stapler only by the magazine is moved in along these two non-parallel longitudinal axes, but in reverse order and in reverse directions of movement. It is particularly advantageous if only the movements along the two different axes or directions of movement are possible for the removal and insertion of the magazine exclusively. Since the movements for insertion and removal are clearly predetermined and are also easy and quick to perform movements, the magazine can be quickly removed and used again quickly. The object is also achieved by the features of claim 15. In this case, it may be particularly favorable if guide means are provided, through which, during an insertion movement of the magazine, the magazine is guided successively in two mutually perpendicular directions. Such movements can be easily understood by a user.

In this case, it can be advantageous in particular if one of the directions of movement runs parallel or at least approximately parallel to the contact surface of the stapling device. In particular, when during the removal taking place parallel to the footprint of the first movement to be performed and the second movement, it is also possible to perform this with the stapler itself, the removal of the magazine in a working position on an object can be done without this from the just lifted and removed. In a further preferred embodiment of the invention, at least one of the two movements is limited by a stop. Preferably, this is the first movement to be carried out, whereby incorrect operation can be avoided. The operator thus has no difficulty in moving from the first to the second movement in the right place.

It may also be advantageous if at least one pivot lever or quick-release lever of the quick-release is provided, which is pivotable about a pivot axis extending perpendicular to the contact surface. Preferably, in the region of both sides of the magazine, in each case one should be pivotable about a respective pivot axis extending perpendicularly to the contact surface. This makes it possible to realize an ergonomically particularly favorable and nevertheless function-safe quick-closing.

To further improve the reliability can also contribute that the pivot lever is biased or biased with a spring element, wherein for removing the magazine of the pivot lever against a spring force of Spring element pivotable about the pivot axis and a latching lug of the pivot lever can be lifted from a detent position.

Preferably, the at least one pivoting lever is arranged on a carrier part of the stapling device and cooperates with a counter element of the magazine. A particularly favorable solution can provide here that the counter element is a plate arranged on the magazine, which limits the ejection channel in the inserted state of the magazine on one side of the ejection channel, preferably a magazine-side side of the ejection channel.

The reliability can be further increased by a preferred embodiment of the invention, when the quick release has self-locking means which prevent the magazine can be removed without actuating a release provided for the magazine solvent. Preferably, by the self-locking in such an attempt, the holding forces of the magazine should increase or further strengthen a positive connection. One of several possibilities for a self-locking may be, for example, that when attempting to remove the magazine without actuating the solvent, the magazine rotates a pivoting lever - as a solvent for releasing the quick release - against a release direction.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings. The invention will be explained in more detail with reference to embodiments shown purely schematically in the figures, in which:

34 three front views, each with a stapling device, which are provided with two mechanical detection means (contact switch) for detecting an object in the area of a footprint, wherein in two partially sectional views showing the detection means in different detection states;

In Fig. 1 as a stapling device, a portable electrically driven stapler 1 is shown, as it is provided in the industrial or commercial field for driving fasteners, in particular of staples, in documents. The provided electrical energy is used for expelling or ejecting staples. The housing has a main housing section 2 and a handle section 3, as will be discussed in more detail below. On the main housing section 2, a removable and removable storage device 4 is arranged, in which a supply of staples can be added. Within the main housing section 2, an ejection mechanism 6 is arranged, which includes a driven by a motor 7 ejector 8, which meets on its acceleration path on the foremost staple from the magazine 4, this accelerated and ejects from an ejection channel 9 and the outlet opening 10. The outlet opening 10 is in this case in the region of a substantially flat footprint 11, with which the stapler 1 is placed on the estate or object to put a staple in the respective object with the stapler 1 in a motor-driven manner.

In the present case, the stapling device is provided for closing cardboard boxes. It therefore has two so-called clinchers 14 (FIG. 3), which are synchronized with the movements of them with the movement of the ejector 8 and penetrate in their movement in the cardboard to the two legs of the respective staple in the direction of a base leg to bend the staple.

The housing may preferably be made of a pourable or injectable plastic and have two composite housing halves. Each housing half thus has a part of the main housing portion 2 and a part of the handle portion 3. The arranged in the main housing section 2 ejection mechanism 6 has a rotationally driven by the motor 7 rotary member which is provided with an eccentrically arranged cam. The cam is guided in a backdrop of a linearly guided lifting element. The lifting element is guided in such a straight line that it executes a rectilinear movement between an upper and a lower dead center, in each of which a direction of movement reversal takes place. The provided on the lifting element backdrop for the cam, has an obliquely to the lifting axis extending first link section and an adjoining at least substantially perpendicular to the Hubachse extending second link section.

On the lifting element a transmission rod is arranged with one of its ends, which is arranged with its other end to a guide element also guided in the stroke direction. At the lower end of the guide element, the ejector is arranged, which performs an oscillating movement together with the lifting element and the guide element between the top and the bottom dead center of their movement. With an end of the ejector facing away from the guide element and the end face provided here, the ejector is provided with its motor-driven path for contact with the staple stapler of the staple supply located respectively in the ejection channel.

On the guide element two clincher 14 are also pivotally connected via a respective lever mechanism 28. Each of the clincher 14 has at its free end on a cutting edge 14a, which in an ejection stroke of the ejector 8 by the pivotal movement of the respective clincher 14 in the object, here the cardboard, penetrates and there one of the two U-legs of the respective bracket 12 in Direction of the base leg of the staple 12 bends to thereby fix the staple 12 against easy withdrawal from the cardboard. Usually, a generic stapler with its contact surface 11 is arranged on the cardboard such that in each case one leg of the clip 12 penetrates into one of the two hinged wings of the cardboard with which the cardboard is to be closed. After the clincher 14, the legs of the staple 12th bent, the clincher 14 are swung back during the upward stroke of the guide element and the link element in the same way from the cardboard, on which they are also in the cardboard and on the underside of the two cardboard wings. The down and the upstroke movements of the link element are thus covered along the same rectilinear path, but in each case in the reverse direction of movement. The movements take place here along a common longitudinal axis, which is arranged centrally in the guide channel of the link element. According to the ejection mechanism 6 motor, namely here electric motor driven. For this purpose, a brushless DC electric motor 7 is arranged in the handle portion 3. Under handle section 3 here can be understood the portion of the housing, which is vorgsehen for a clasping by the hand of a user when this uses the stapling device and leads by hand. This electric motor 7 is in this case, at least with a portion with respect to its longitudinal extent, within the handle portion 3 approximately at a point at which the handle portion on its outside a recessed grip 3a, which provided for the arrangement of the operating hand and fingers of the operating hand of each user and is determined. In the region of the recessed grip 3a, the user grips around the handle section 3 and can thus actuate an activator 29 arranged in the region of the recessed grip 3a in an ergonomically favorable manner with the index finger. The trigger 29 is thus located directly next to the motor 7 and the Leistungsprint 25. By pressing the trigger 29, the ejection of a clip can be set in motion.

In the handle section 3 is also a power electronics board 25, which is provided for controlling the motor 7 and for controlling the motor current. At the handle portion 3, a receptacle for a removable and usable rechargeable battery 26 is also provided in the region of the free end. In the exemplary embodiment, the Leistungselektronikprint 25 is located between the accumulator 26 and the electric motor 7. Also, a required wiring 30 between the accumulator 26 and the Leistungselektronikprint 25th and between the Leistungselektronikprint 25 and the electric motor 7 is also located in the handle portion 3 of the housing.

As can be seen in FIG. 1, the axis of rotation 7a of the electric motor is aligned at least approximately parallel to the contact surface 11 of the stapler. As can also be seen in FIG. 1, the axis of rotation 7a of the electric motor is aligned at least approximately, preferably as exactly as possible, perpendicular to the longitudinal axis 13 of the guide or ejection channel for the staples, and the rectilinear movement axis 13 of the lifting element. To the electric motor, a planetary gear 27 is added, with which the respective engine speed is reduced, i. is changed in the slow. The gear output side rotation axis of the planetary gear 27 connected to the motor rotation axis 7a is aligned with the motor rotation axis 7a. With the gear output side drive movement, the crank of the ejector mechanism and the ejector 6 then the ejector 8 and the clincher 14 are driven. The motor rotation axis 7a has approximately the same distance to the contact surface 11 as an introduction point of the motor rotational movement from the transmission 27 or electric motor 7 into the ejection mechanism 6.

The preferred embodiment of the invention is provided with a further aspect of the present invention which may also be independent and independent of other aspects of the invention. This aspect relates to the trigger 29 which has a detection means 31 for detecting a body part arranged on the trigger, in particular a finger. This detection means 31 can either be arranged directly on the trigger 29 or else on the housing of the stapling device in the immediate vicinity of the trigger 29. The detection means for detecting a body part arranged on the trigger can be designed as a proximity sensor, as a photodiode or a photoresistor. By means of a signal cable laid in the housing, a detection signal of the detection means can be fed to a controller of the stapling device, wherein the controller is set up such that the detection signal is a prerequisite for releasing an ejection of a staple. Finally, the trigger 29 is preferably actuated against the spring forces of at least two spring elements 17, 18. Upon actuation of the trigger 29, this is initially only against the spring force of the first spring 17 and only in the course of further actuation of the trigger then the second spring 18 acts with its spring force against the trigger 29. Once the second spring 18 due to an advanced actuation path the trigger 29 further depressing the trigger 29 their spring force as a compression spring opposes, thus the spring forces of both spring elements 17, 18 and the trigger is from then against both spring elements 17, 18 to be actuated.

In the area of the footprint 11 of the mobile portable stapler is located on both sides of the outlet opening 10 each have a detection means 19, 20, with the presence of an object immediately below the footprint 1 1 and thus below the outlet opening 10 is detectable. With these two detecting means 19, 20 (sensors) should thus be determined whether the stapling device is disposed on an object into which a clip 12 can be dispensed. It is preferably provided that both detection means 19, 20 detect the object and in each case have to provide a corresponding signal to the control, so that a clamp 12 can be released for expulsion by the controller. This can prevent brackets from being ejected without the presence of a corresponding object and possibly injuring persons. By at least one detecting means 19, 20 at each end face of the outlet opening 10, it can also be detected whether the complete outlet opening 10 or not only a part thereof is located on an object. The at least two detection means 19, 20 thus have a distance from each other which is greater than the length of the outlet opening 10. This also prevents the ejection of staples, which are then located in one object with only one leg and thus not in able to perform their intended function.

The two detection means 19, 20 are preferably designed as optical sensors. But in other embodiments of the invention can also mechanical sensors or sensors based on other functional principles may be provided. Apart from other optical sensors, for example, those which emit light and detect a reflection of the emitted light can be suitable. Such optical proximity switches are offered in many different embodiments for a long time, which is why their structure will not be discussed further.

Finally, in the figures, representations are also included, in which preferred embodiments according to the invention of a stapling device are shown in which, instead of optical detection means in the contact area 11, mechanical contact switches can be provided as detecting means 119, 120. These detection means 119, 120 may be arranged at least substantially at the same locations of the footprint 11 on which the optical detection means 19, 20 are provided.

The preferred embodiment of the invention is provided with a further aspect of the present invention which may also be independent and independent of other aspects of the invention. This aspect relates to the possibility of setting a semi-automatic mode and / or a fully automatic mode in addition to a single ejection mode of in each case (only) one clamp per actuation of the trigger 29. This semi-automatic mode can be switched on and off at a display / operating device of the stapler in each case by pressing a button, here, a key of a membrane keyboard 33. By switching on the semi-automatic mode, after a single actuation of the trigger 29, a stapling operation is made possible as soon as certain conditions for the individual stapling operations that then take place automatically are fulfilled. Such conditions may in particular be that both the detection means 36 of the trigger 29 detect a finger and the detection means 19, 20 in the region of the outlet opening 10, an object. If such detection signals of the detection means 19, 20, 36 are missing, it can be provided that no release for a first clamp 12 is already taking place. However, due to such detection signals, a first bracket is released and thus In this operating mode, no further actuation of the release has to be made for the output of further clips.

Conditions for triggering a stapling operation in the semi-automatic mode can thus be, for example, that detection means determine that the contact surface is located on a surface of an object. After execution of the first stapling operation in the semiautomatic mode, it may also be a condition for a subsequent stapling operation of the same body in semiautomatic mode that an intermediate removal of the contact area 11 from the object and then again a presence of the object in the area of the contact area 11 are detected by means of the detection means 19, 20 becomes. In other words, it must be detected that the stapler has been lifted off the object and put back on. It can also be provided that it is determined by means of a further detection means that an operator has placed a finger on the trigger, but without that the operator must press the trigger. In alternative other embodiments, however, it can also be provided that a series of staple ejections in the semi-automatic mode can only take place when the trigger 29 is actuated continuously. It is possible that detection means, such as in particular optical proximity sensors, already signal the presence of an object when the respective sensor is already in close proximity to the respective object, but there is still no contact between the stapling device and the object. In order to prevent staples from being ejected too early in the semi-automatic mode, ie at times at which the stapling device with its contact surface 11 is not yet completely arranged on the object, a time delay of the respective staple ejection may be provided after such detection signals. The time delay can either be stored in the controller as a permanently preset time value or else be adjustable by an operator on the stapling device, in particular be adjustable from a range of time values. Possible time delays, for example, values from a range of 5 milliseconds to 350 milliseconds, but preferably from a range of 10 milliseconds to 200 milliseconds. In the embodiment, a value of 50 milliseconds is provided.

In addition to the manual operating mode, in each case an actuation of the trigger for each individual staple ejection is required, finally, alternatively or preferably in addition to the semi-automatic mode also a (full) automatic mode is possible. In this preferably third and instead of the other two modes of operation adjustable operating mode of the stapling device, after detection of the fulfillment of at least one release condition and after actuation of the trigger 29 as long staple ejections can be done as the trigger 29 is permanently pressed or pushed and the footprint 11 uninterrupted located on an object. It is thereby possible and provided, for example, for the stapler 1 to be pulled over an object and for the ejection of a staple from a series of staple ejections to take place at a specific time interval. Once either the trigger 29 is released and / or the stapler is lifted off the object, the controller stops ejecting further staples.

Finally, in connection with the automatic mode, it may also be provided that the time interval (interval) can be changed from one staple ejection to the respectively immediately following staple ejection. In one possible embodiment, this interval may be adjustable at the stapling device 1 by a user as a value by a corresponding input. Alternatively or additionally, it can be provided in a further possible preferred embodiment that the interval is predetermined in a teach-in (learning) mode of the stapling device. For this purpose, the time interval in which a user emits two staples by means of the stapling device can be stored in an adjustable teach-in mode. This interval is then adopted for the automatic mode. As a result, the automatic mode can be adapted to the mode of operation and working speed of a user.

In the area of the footprint 11 is in the region of the two short side edges of the outlet opening 10 of the ejection channel 9 on both sides in each case a detection means 36 arranged to detect an object. With this detection means 36 can be determined whether the stapling device with its footprint 11 is located on an object and thus a stapling process can be released. Detection signals of the detection means 36 are passed to the control of the stapler and taken into account there for controlling the stapler. The detection means 36 can operate according to different principles of action, for example as mechanical or as optical detection means.

In the figures, the stapler with inserted magazine 37 is shown in an oblique view from behind. In the magazine, a supply of staples 12 is used, which is pressed with a spring-loaded pusher 38 in the direction of the ejection channel 9 of the stapler. The respective foremost of the U-shaped brackets 12 is thus always in the discharge channel 9, in which it is detected by the ejector 8 during its movement, accelerated and pressed out of the outlet opening 10.

In this illustration of the figures, a pivot lever 40 and its pivot axis 41 can be seen on each side of the magazine 37, wherein the pivot lever 40 and its pivot axes 41 each belong to a quick release, with which the magazine on the stapler 1 releasably fastened and by loosening the Quick release is also removable. Thus, located on the opposite side of the magazine, a first and a second pivot lever 40, both of which are pivotable about their pivot axis 41. The two pivot axes 41 are parallel to each other and at least substantially perpendicular to the contact surface 11. Finally, the two pivot axes 41 are also aligned parallel to the longitudinal axis of the ejection channel 9.

As shown in the cross-sectional illustration of the figures, the main housing section of the stapling device has two guide bodies 42 arranged at a distance from one another for the magazine 37. Each of the two guide bodies 42 is provided with guide elements for the approximately rectangular cross-section magazine. On their walls, the guide body 42 are with Guide elements 43 for movement of the magazine 37 parallel to the footprint 1 1 and with one or more stops, to limit this movement. In the exemplary embodiment, these guide elements 43 are parallel to the footprint 11 extending recesses, here slot-like recesses, in the guide bodies. As stops 43a are used in the embodiment, respectively, the ends of the slot-like recesses.

In the exemplary embodiment, the slot-like recesses go over in rectangular recesses of the walls of the guide body 44. The likewise rectangular recesses 44 serve as guide elements for a clearly guided relative movement between the magazine 37 and the housing of the stapling device. Upper frontal wall boundaries 44a of the recesses 44 in this case represent the stops for taking place through the recesses 44 motion guide in the direction perpendicular to the footprint. Seen from the bottom open rectangular shape of the recess 44 closes thus in the upper frontal wall boundary in each of the two substantially rectangular recesses 44 each of the parallel to the footprint 1 1 and in the direction of the ejection channel 9 extending slot as a guide member 43 at. In the preferred exemplary embodiment described here by way of example only, each of the two guide bodies thus has two identical guide elements 43, 44 arranged next to each other.

The magazine 37 is provided in the discharge channel side region of its side walls 46, each with two spaced apart tabs 47. The tabs 47 are perpendicular from the outer surfaces of the side walls 46 and have a substantially parallel alignment with the contact surface 11 in a magazine 37 inserted into the stapler 1. The tabs 47 are spaced apart and dimensioned such that they are arranged in the recesses of the guide elements 43, 44 of the guide body and there along the respective longitudinal extension of the recesses - and only along these longitudinal extensions - can be moved. To attach a magazine 37 to the stapler 1, the tabs 47 become from the lower open side introduced the guide elements 44, so that the tabs 47 are parallel displaced in the guide elements to the footprint 11 until the respective tab 47 reaches the upper end face (stop) of the respective recess of the guide member 44. This direction of movement is aligned perpendicular to the footprint 11. Now, the respective tab 47 can be moved parallel to the footprint 1 1 in the respective slot-like recess of the respective guide member 43 until the tabs 47 simultaneously reach their respective stop 43a. The slots of the guide elements 43 and a thickness of the tabs 47 are dimensioned such that the tabs 47 are inserted into the respective slot of the guide elements 43 after reaching their stop 44a in the respective guide element 44 and can perform a movement substantially parallel to the footprint. When inserting a magazine 37, the first movement of the magazine 37, or of its tabs 47, in the recesses of the guide elements 44 and the second movement of the tabs 47 in the slots of the guide elements 43, thus perpendicular to each other. To remove the magazine from the stapling device 1, the slots in now reversed direction of movement, but along the same path, led out of the guide members 43, 44. Both when inserting and when removing a magazine 37, it is possible to guide the stapling device 1 along the described path instead of the magazine 37. Decisive are only the corresponding relative movements between the magazine 37 and the guide bodies 42 of the stapler. 1

In each of the two guide body 42 is guided on both sides in the region of the magazine 37 by the respective guide body 42, one of the pivot axes 41 and the guide body 42, preferably designed as a compression spring spring element 49 supported and arranged. The respective pivot axis 41 is arranged at a distance from the spring element 49 (pressure spring) and in this case has a smaller distance to the ejection channel 9 than the respective spring element 49 of the same magazine side. Each of the pivot axes 41 extends at least substantially perpendicular to the contact surface 11 of the stapler and at least substantially parallel to the longitudinal axis of the ejection channel 9. The pivotable about its respective pivot axis 41 arranged pivot lever 40 can thus perform pivoting movements about this axis, which lie substantially in a pivot plane which extend parallel to the footprint 11. The respective pivot axis 41 is also guided through one of the pivot levers 40.

The respective guide body 42 is in this case between the magazine 37 and belonging to this magazine page pivot lever 40. On its outer side, each of the pivot lever 40 has a shoulder 50. The shoulder 50 is provided for abutment against a surface of a carrier body of the stapler 1 and thus serves to limit the insertion depth of the magazine 37 in the stapler. In addition, each of the two pivot levers 40 is curved at its output-side end in the direction of the magazine 37 and provided with a profiled front side 45 (Fig. 7 - 12). The stapling device 1 has in the region of its magazine-side opening, which is also in the region of the ejection channel 9, a rear plate 51 which limits the ejection channel 9 in the inserted state of the magazine 37 on the magazine side and is part of the magazine 37. The rear plate 51 extends beyond the rail on both sides of the magazine 37, in which staples 12 are stored. Side surfaces of the rear plate 51 are located approximately at the height of the outlet channel side ends of the pivot lever 40. The end faces 45 of the pivot lever ends are each provided with two an obtuse angle Teilfächen 40a, 40b, which cooperate with the respective side surface 51a of the rear plate 51.

In order to release and remove the magazine 37 fixed in the stapling device 1, for example due to a staple jam, or to replenish the magazine 37, the two pivoting levers 40 must first be actuated about their respective pivot axis 41 and counter to the spring force of the spring elements 49. In an inserted and latched on the quick release magazine 37, the rear portions 40c of the pivot lever 40 are at a distance from the respective guide body 42. These pivot lever sections 40c are through the Spring element 49 from the guide body 42 in the form of a torque about the pivot axis 41 pushed away. A pivotal movement of the pivot lever 40 caused thereby is limited by a respective stop of the shoulder 50 of the pivot lever 40 on the carrier body or on the housing of the stapler. An actuation of the pivot lever 40 now leads first to a pivoting movement about the pivot axis 41 against the spring force, so that the rear portions 40c of the pivot lever 40 come into abutment against the guide body 42, as shown in Figures 7, 8, 9, is shown. The profiled end faces of the front ends of the pivot lever 40 are in this case of their identical locking positions on the rear plate 51, in which the two mutually angled faces 40a, 40b of the profiled end faces of the pivot lever 40 abut against an edge region of the front side of the rear plate 51, from the lifted off the rear plate 51. The magazine 37 is thereby released for an excerpt from the guide (guide elements 43, 44), the quick release is thus solved.

As long as the respective end face of the pivot lever 40, however, bear against the end face 51 a of the rear plate 51 and the quick release is not released by hand, the quick release is locked self-locking. A pull on the magazine 37 results in that due to the geometry of the front ends of the pivot lever 40, the rear plate 51 has the tendency to pivot both pivot levers 40 counter to their rotational direction when releasing the quick release about their pivot axes 41. This leads to an increase in holding forces, which are exerted by the carrier-side or housing-side pivoting levers 40 on the magazine-side rear plate 51.

After the quick release is solved as described, the magazine 37 can be spaced with a parallel to the footprint 11 extending movement of the housing. The direction of this movement is determined by the slots of the guide elements 43 and the tabs 47 guided therein. The movement is stopped as soon as the tabs 47 abut against side boundary walls of the recesses of the guide elements 44. In this position, there are all tabs 47 with their entire longitudinal extent within the Recesses of the guide elements 44 and that at the upper ends. By moving the tabs 47 within the recesses of the guide members 44 toward the open lower end of the recesses, or alternatively, moving the recesses along the tabs 47, the magazine 37 can be completely removed from the stapler. A simple us safe way to remove the magazine 37 may thus be to turn off the stapler 1 with its footprint 11 and the bottom of the magazine 37 resting on a pad and the pivot lever 40, which can also be called quick release lever to press. Subsequently, the magazine 37 is pushed parallel to the footprint 11 in a first direction to the stop of the tabs 47. Thereafter, the stapler relative to the magazine can be raised perpendicular to the footprint 11 until the recesses of the guide elements 44 are removed from the tabs. The magazine 37 is now separated from the stapler 1 and freely accessible.

For inserting the magazine 37 into the stapling device 1, the aforementioned movements between the magazine 37 and the stapling device 1 can then be carried out in the reverse order and in the reverse direction of movement (FIGS. 10, 11, 12). The magazine 37 can be recognized with its tabs 47 from below to the recesses of the guide elements 44. With a movement of the magazine 37 perpendicular to the footprint 11, the tabs 47 can be inserted into the recess and guided to the first stop. Subsequently, the magazine 37 can be moved perpendicular to the first movement in the direction of the ejection channel 9. The arranged on the magazine 37 rear plate 51 comes here in contact with Ausstoßossseitigenseitigen ends of the pivot lever 40 and pivots it against the spring force of the spring elements 49 about their respective pivot axis 41. The rear plate 51 can thereby pass the pivoted pivot lever 40, whereupon by the spring elements loaded pivot lever 40 pivot back into its locking position in now opposite pivot direction. Due to the acting spring force, in this case the pivot levers 40 snap back, which can serve as an indication for a correctly arranged magazine 37 in its end position for the operator. Like in the enlarged representation of one of the figures can be seen here passes one of the faces 40a of the front end side of the respective pivot lever 40 in front of the rear plate 51 and locks it against an excerpt of the magazine 37. The other part 40b of the front end face is against the side surface (Front) 51 a of the rear plate 51 and is thereby prevented from further movement about the pivot axis. The pivot lever 40 thus remain in this position. In addition to the magazine 37 so that the rear plate 51 is arranged in the intended position for them on the stapler 1, in which it limits the discharge channel 9 magazine side.

To increase the certainty that the stapling device can not be triggered when no magazine is inserted into the stapling device, the stapling device has a blocking device which is provided with a movable blocking means. The blocking means can be pivoted into the path of movement of the ejector 8, so that the ejector 8 can not perform any lifting movement. The blocking means can in this case be arranged in two end positions, wherein the blocking means is in the first end position outside the movement path of the ejector 8 and thus releases the ejector for its lifting movement for ejecting a clamp. In the second end position, however, the blocking agent is in the path of movement and thus blocks the ejector.

In the illustrated preferred embodiment of the invention, the blocking means is designed as a pivotable pawl 55 which is arranged on a shaft 56 and pivotable about the longitudinal axis of the shaft 56. The shaft 56 and its pivot axis are in this case aligned perpendicular to the lifting movement of the ejector 8 and parallel to the base leg 12a of each arranged in the magazine staples 12. The pawl 55 has two legs 55a, 55b, the one leg 55a is located on one side of the shaft 56, the other leg 55b is located on the opposite side of the shaft The pawl 55 has at its lower, that of the outlet opening 10th In addition, presses against the other leg 55b, a compression spring 58, which thereby tends to the leg 55b in the direction of the Ejector presses. Otherwise no force acts against the pawl 55, the force of the compression spring pivots the pawl 55 with its leg 55b into a groove 8a of the ejector 8. In this end position, the leg 55b of the pawl 55 thus blocks the ejector against movement in the ejection channel 9.

By inserting a magazine 37 in the stapling device pushes a component 59 of the magazine shortly before reaching the end position of the magazine in the stapler 1, against the leg 55a of the pawl. During the movement of the magazine 37 parallel to its longitudinal extension, the component of the magazine detects the driving lug 57 of the pawl 55 and pivots the pawl 55 against the spring force of the compression spring, so that the leg 55b from the groove of the ejector 8 and thus also from the trajectory the ejector 8 is pivoted. When the magazine 37 reaches its end position, it holds the pawl 55 in abutment against the catch lug 57 in a second end position, in which the pawl 55, in the illustration of FIGS. 13, 14, is oriented substantially vertically and parallel to the discharge direction of the clamps. The pawl 55 is located in this second end position outside the discharge channel 9 and thus releases the Aussstosser for ejection movement. Upon renewed removal of the magazine 37, this then releases the catch nose 57 and thus the pawl 55 again. The pawl 55 can thereby be transferred during the removal movement due to the force of the compression spring 58 back to its final position in which it blocks the ejector 8.

As can be seen from FIGS. 17, 18, the magazine is provided with a fill level indicator 60. For this purpose, a marking 61 is attached to one or more fixed parts of the magazine 37, which indicates the degree of stock filling of staples in the magazine. The markers can, for example, along the Vorratsbzw. Stacking direction of the brackets in the magazine have optically perceptible differences that stand for a different degree of filling or symbolize such. The optical differences can be, for example, differently colored partial markings 61 a, 61 b, 61 c. In particular, a minimum level mark, from which the magazine refilled is to be marked with a signal color, such as red, especially a signal red. Of course, other types of marks are conceivable and possible, for example, different geometric shapes. Also, an acoustic signal, either in addition or alone, when reaching a minimum level can be provided.

The magazine 37 also has a display or indicating means 63 which moves together with the staple stack which reduces during the use of the work, and which signals the current level of the magazine 37 with staples 12 at the markings 61. A particularly favorable solution can provide here that a spring-loaded carriage 64, with which the stack arranged in the magazine 37 is pressed on brackets 12 in the direction of the ejection channel 9 of the stapler 1, for displaying or indicating the filling level by means of the one or more markings 61 serves. A structurally simple embodiment can provide, for example, that an end face of the carriage 64, with which the carriage rests against the staple stack, indicates or represents the respective filling level at the markings. The solution realized in the exemplary embodiment provides an arrow 62 arranged on the carriage and directed at the markings as indicating means 63. The arrow can be arranged, for example, on a handle portion of the carriage 64, with which the carriage also manually moved in the magazine 37, in particular retracted for receiving Klammem, can be.

In the figures, preferred embodiments of further inventive aspects are shown. Thus, for example, in FIGS. 20-28, the stapling device 1 is shown with its housing, wherein the stapling device 1 has a light emitting means 70 emitting from the housing. The light emitting means 70 is located on the front side 1 a of the housing. In the exemplary embodiment, this light emitting means 70 is a line laser, which is arranged in the housing above the ejection channel 9. The laser 70 radiates from a housing opening 71 forward, in front of the stapler 1. As can be seen in Fig. 20, 21, the line laser emits as a light beam 72 on the respective object directed light plane. On the object, this light plane can be perceived as a projected, straight line 72a. Since the laser 70 preferably radiates out of the housing opening 71 in the most exactly central housing dividing plane, which is also arranged centrally in relation to the ejection channel 9 and centrally to the base leg 12a of the brackets, in particular the brackets 12 located in the ejection channel 9, the projected Line 72a the center of the base legs 12a of the ejected staples 12 again. In order for a user of the stapling device to set the staples 12 as accurately as possible, he can orient himself on the line 72a projected onto the respective object, which indicates the center of the base leg 12a with respect to the longitudinal extension of the base leg 12a should be in this position of the stapling device Staple ejection take place. The line laser 70 thus has the function of a positioning aid and the user can orient himself on the projected line 72a in order to achieve a specific orientation of the stapling device 1 and thus a specific orientation of a clamp 12 intended for ejection.

It is further preferred here that the light emitting means 70 embodied here as a line laser, as well as any other light emitting means conceivable as a positioning aid, can be switched on and off, for example via a switch or a key on the stapling device 1. Likewise, in a particularly preferred embodiment a stapling device according to the invention can be provided that an automatic switching on and off of the respective Lichtemittiermittels provided upon presentation of certain conditions, in particular as a function on and off, is. For example, an automatic power on may occur when an operator touches the trigger 29 or a finger approaches and is detected. Additionally or alternatively it can also be provided that the at least one detection means 19, 20 in the area of the footprint 11, the presence of an object must detect directly below the footprint 1 1 so that automatically the respective Lichtemittiermittel is turned on to display an optically perceptible position information with respect to a clip position , The line laser 70 has a circular cross-section housing 74, which is disposed within the housing of the stapling device 1 in a holder 75. The holder 75 has for this purpose also a circular in cross-section receptacle 76, in which the line laser 70 is arranged and mounted. A longitudinal axis of the circular receptacle 76 is hereby directed obliquely downward onto the respective object and at a distance in front of the stapling device 1. On the outer surface 74a of the housing 74 of the line laser 70, an elastically stretched O-ring 77 is arranged. A portion of the O-ring 77 is in this case in a recess 78 of the wall of the holder 75, so that this portion of the O-ring 77 is accessible for access. By a rotational actuation of the O-ring 77 through the recess 78, it is possible to change the rotational position of the line laser 70 in its holder 75. The tightly mounted on the housing 74 of the laser 70 O-ring 77 takes the laser 70 with this operation, so that the laser 70 rotates in the holder 75. The likewise present slight clamping of the O-ring 77 in the holder 75 is overcome in the operation and allows to make very small rotation angle of the laser 70 in the holder 75 and set.

The rotation of the laser 70 can change the orientation of the line 72a projected by it onto an object. A deviation of the actual rotational position from the intended target position which may possibly be produced during the mounting of the laser 70 in the holder 75 may result in the projected (light) line 72a having an at least slight oblique course with respect to the base leg 12a of the respective clamp 12 , By means of the O-ring 77 and the recess 78 in the holder 75, a correction of such misalignments can be made easily and quickly and the laser can be aligned exactly to its desired position. Such a correction can also be made easily and quickly even after assembly and delivery of the stapling device, should show such use or misalignment only in use.

In the drawings, two further light emitting means 80 are shown, which also indicate position information about a staple 12 to be ejected. These Both Lichtemittiermittel can also be designed as a laser, in particular as a line laser. The two identically constructed Lichtemittiermittel 80 are located on one side of the stapler under the housing and in each case substantially above the discharge channel. The respective line laser 80 also emits its light from one housing opening at a time, obliquely downwards onto the respective object, and in turn can be visually perceived there as a straight projecting line. The structure and arrangement of the two line lasers 80 and their arrangement in a holder including an adjustability may be provided according to the solution of the laser 70.

Each of the two lasers 80 emit a light plane on different sides of the stapler, each projecting on the respective object a line 80a each aligned perpendicular to the line 70a and aligned with a center line of the ejection channel. The lines 80a further align with the base leg 12a of a clip 12 to be ejected. Further, the lines 80a projected by the lasers 80 on both sides of the stapler align with each other. The two light emitting means thus signal the longitudinal course of a base leg 12a of a clip to be ejected or the plane in which the three legs of a clip 12 to be ejected are located. Thus, the cooperating two Lichtemittiermittel 80 serve as a positioning aid to eject a clip in a predeterminable position or put into an object.

In an alternative embodiment of the invention, the light emitting means 70, 80 may also be formed with light sources other than lasers. Thus, in other embodiments, in particular lasers can be replaced by one or more LEDs 86. In particular for LEDs as light emitting means 80, a type of light well 85 may be formed on the housing, which preferably has a transparent, at least partially transparent, cover 84. The respective light shaft 85 preferably runs in the plane whose position is to indicate the respective light emitting means. Does the stapler thus on both sides of the stapler 1 each have a light shaft with arranged therein at least one each switched on and off the luminous LED, each of the two light wells 85 should each be within the bracket plane formed by the three legs of each clip to be ejected. In a preferred development of the stapling device 1 according to the invention, one or more light emitting means can also be provided in a light shaft, in particular also those which can illuminate in different colors. Alternatively, two or more Lichtemittiermittel may be provided in a light well, each of which lights in only one but not identical colors. However, different colors can also be produced as light emitting means. With such embodiments it is possible, in addition to position information, also to signal one or more further operating or status information, for example if the stapling device 1 is ready for use and / or if there is a malfunction and / or in which mode the stapling device is located and / or whether the detection means of the trigger 29 has detected a finger on the trigger 29. Instead of or in addition to different colors, flashing signals of the light emitting means or otherwise varying light emissions of the respective light emitting means can also be provided for optically perceptible information switching.

In the figures, as a membrane keyboard 33 display / operating device of the stapler is recognizable. The membrane keyboard is arranged in the preferred embodiment on an inclined side surface of the main housing portion 2 of the stapling device 1. This membrane keyboard 33 may have keys for various adjustable or retrievable functions. In particular, the membrane keyboard for adjusting the operating modes can be provided with one or more keys. Likewise, the membrane keyboard 33 may be provided with visually perceptible display means to optically signal set functions, values, fault conditions, state of charge of the accumulator and / or operating modes. Such display means may be integrated into the membrane keyboard bulbs and / or alphanumeric displays. Optionally, illuminants and / or alphanumeric displays can also be integrated in keys of the membrane keyboard. The bulbs and / or The at least one alphanumeric display can optionally display visual information in different and changing colors, just as a flashing mode is possible for them. In this way, particularly by means of warning colors, such as red, be pointed to particularly important information. In other embodiments according to the invention, the stapling device can also be provided with alternative display and operating means. Such may be, for example, a touch screen.
