Definitions

• the invention relates to a stapling device with an upwardly directed broad side surface and two elongated bottom parts adjoining the longitudinal edges of the broad side surface, with a magazine for receiving staples, which is pivotably mounted on a bearing block at one end of the bottom part about a transverse axis a driver for ejecting the staples having upper part, and with one near the end of the base part opposite the bearing block in the longitudinal direction, preferably in two locking or end positions, with their upward facing towards the top ⁇ ren broadside surface of the bottom part parallel surface with deformation embossments for the legs of the ejected staples provided anvil plate.
• the magazin head which extends to the vicinity of the anvil plate and is arranged on the upper part, disturbs.
• the function of the adjustment mechanism is not readily recognizable from above and therefore needs to be explained. Apart from this, the device for adjusting the anvil plate must be lifted off its base.
• the invention is based on the object of developing a staple device in which a simple adjustment of the anvil plate and nevertheless a good latching action in its end positions is ensured.
• the solution according to the invention is based on knowledge from the fact that pincer-like grasping of an object between the thumb and index finger without the aid of an abutment, such as a table mat, can transmit relatively large clamping forces and thus also frictional forces to the object. Accordingly, if two relatively large gripping surfaces for the thumb and forefinger are provided on the anvil plate, a favorable transmission of the force of the fingers to the anvil plate is possible. In order to achieve this, it is proposed according to the invention that handle flaps are provided on the opposite longitudinal side edges of the anvil plate perpendicularly in the direction of the narrow side surfaces of the base part and partially overlapping grip surfaces which face one another on opposite sides.
• the mutually opposite grip surfaces are at a distance from one another on the bottom part of a staple device, which is optimal for ergonomic grip guidance.
• the grip tabs are visible in the functional position of the stapler. They can additionally be provided with corrugation or roughening, so that their function is easily recognizable and does not require explanation. If the stapling device is gripped by hand over the upper part, it is even possible to shift the anvil plate with one hand without the aid of an abutment formed, for example, by a table top.
• the grip tabs are advantageously designed as edge portions extending over the entire length of the anvil plate. bends formed so that the anvil plate has a substantially U-shaped cross-sectional profile together with its side poison bottles.
• An advantageous embodiment of the invention provides that the grip tabs each engage in an open-edge recess in the narrow side surfaces of the base part, the grip surfaces of the grip tabs recessed in the recess being flush with the adjacent narrow side surfaces or less than the material thickness of the Handle tabs protrude over them.
• the anvil plate as such is also expediently recessed in a recess in the broad side surface, it being possible for the recesses in the broad side surface and the narrow side surfaces to merge into one another and to be delimited by mutually aligned end-face stop flanks for the anvil plate and its side tabs.
• the anvil plate is guided on two guide webs which are arranged at a lateral distance from one another, are arranged in the longitudinal direction and are recessed in relation to the broad side surface and are formed on the base part and which expediently have a curved upper edge.
• the guide webs, which are recessed in relation to the narrow side surfaces, are advantageously overlapped on the outside by the grip tabs bent on the anvil plate.
• two openings which are arranged in the broad side surface of the base part and are spaced apart in the longitudinal direction and are separated from one another by a transverse web, are essentially bent at right angles to the transverse edges of the anvil plate the openings in the bottom part reaching through and holding tabs clamped between the two holding tabs, aligned in the longitudinal direction of the bottom part and preferably made of plastic as a leaf spring, overlapping the web on the underside of the bottom part and on it in at least two locking positions snap-in detent spring provided. If the web and the detent spring have mutually complementary detent members on their mutually facing sides, the detent spring is only subjected to bending during displacement, while wear-prone transverse loads are avoided.
• side guide surfaces for the retaining tabs which are aligned in the longitudinal direction in pairs in the longitudinal direction in the area of the openings are arranged, preferably integrally formed, on the base part.
• the narrow side surfaces in the region of the open-edged recess do not have any side guide function that is susceptible to wear. If, in addition, the holding tabs opposite on the transverse edges of the anvil plate have different transverse dimensions and the side guide surfaces in pairs have a different, the transverse dimensions of the have appropriate spacing from one another, it is ensured that the anvil plate is mounted in the correct orientation on the base part.
• the holding tabs expediently each have an eyelet for receiving the leaf spring, while the leaf spring is provided with end-side anchoring and / or centering cams which overlap the respective eyelet edge on one or both sides.
• the leaf spring can be pretensioned in the bending direction against the end eyelet ends via the central latching members and can be easily mounted if the eyelet size is large enough.
• the web-side locking elements are expediently designed as a triangular rib with opposing run-up slopes, while the spring-side locking elements can have a spherical, preferably partially cylindrical or spherical locking surface.

• the anvil plate is embossed 28 on its broad side surface 26 , 30, which, depending on the displacement position of the anvil plate 24, are located directly under the driver 22 and the discharge channel 32 of the staple magazin 16 and are intended for deforming the legs of the staples for inside or outside stapling.
• the anvil plate 24 has on its longitudinal edges 34 vertically downwardly bent grip tabs 36 which, with their gripping surfaces 40 carrying a corrugation 38, face opposite sides and engage in open-ended recesses 42 in the narrow side walls 44.
• the anvil plate 24 rests with its plate part on two guide webs 46 which are arranged at a lateral distance from one another and are countersunk with respect to the broad side surface 26 and which have an upper edge 47 curved in the transverse direction and with their outer edge side flank delimit the adjacent edge-open recess 42.
• retaining lugs 50, 52 are each bent downward in the central region, which reach downwards through two openings 54 of the base part 10 arranged at a distance from one another and in their lower one Area are provided with eyelets 56.
