Definitions
- the invention relates to a staple device with an elongated base part with an upward-facing broad side surface and two laterally adjoining narrow side surfaces, with a magazine for receiving staples and a driver for ejecting the staples, which is pivotably mounted on a bearing block at one end of the base part about a transverse axis having upper part, and with a near the end of the base part opposite the bearing block in the longitudinal direction, preferably in two latching or end positions, provided on its upward-facing surface parallel to the upper broad side surface of the base part with deformation embossments for the legs of the ejected staples
- Anvil plate on the opposite longitudinal side edges of the anvil plate preferably bent perpendicularly in the direction of the narrow side surfaces of the base part and at least partially overlapping one after the other grip tabs with opposite sides are provided.
- the invention has for its object to develop a stapler of the type specified, in which on the one hand a flat, self-cleaning side guide of the anvil plate displaceable in the base part and a good locking effect of the anvil plate in its end positions is ensured, and on the other hand it is ensured that the Anvil plate is mounted in the correct orientation on the bottom part.
- a parallel guidance of the anvil plate on the base part in the area of the openings is achieved with the lateral guide surfaces according to the invention and the holding tabs guided on them.
- the narrow side surfaces in the area of the grip tabs bent downward do not have any wear-prone cornering function.
- the holding tabs opposite one another on the transverse edges of the anvil plate have different transverse dimensions and the lateral guide surfaces in pairs have a different, the transverse dimensions of the associated Holding tabs adapted, clear distance from each other, it is ensured that the anvil plate is mounted in the correct orientation on the bottom part.
- the grip tabs are designed as edge bends extending over the entire length of the anvil plate, so that the anvil plate together with its lateral grip tabs has a substantially U-shaped cross-sectional profile.
- An advantageous embodiment of the invention provides that the grip tabs each engage in an open-edge recess of 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 projecting beyond them by less than the material thickness of the grip tabs.
- the anvil plate as such is also expediently sunk in a recess in the broad side surface, the recesses located in the broad side surface and the narrow side surfaces merging into one another and being able to be delimited by mutually aligned end 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 aligned in the longitudinal direction and are countersunk with respect to the broad side surface and are formed on the base part and which advantageously have a transversely 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.
- 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 against the end eyelet edges in the bending direction via the central latching members and can be easily assembled with a correspondingly large eyelet dimension.
- the web-side locking members are expediently designed as a triangular rib with opposing bevels, while the spring-side locking members can have a spherical, preferably partially cylindrical or spherical locking surface.
- the detent spring If the web and the detent spring carry mutually complementary detent members on their mutually facing sides, the detent spring is only on when moving Bending is stressed, while wear-prone transverse loads are avoided.
- 1 and 2 essentially consists of a base part 10 with a bearing block 12 arranged at the rear end of the base part 10, an upper part 14 with a clip magazine 16, driver holder 18 and cap 20, and a driver 22 preferably suspended on the driver holder 18 for ejecting staples arranged in the staple magazine 16, as well as an anvil plate 24 which is displaceable in the longitudinal direction in the longitudinal direction thereof and which can be latched into two end positions after the anvil plate 24 has been moved, are located directly under the driver 22 and the ejection channel 32 of the staple magazine 16 and are intended for deforming the legs of the staples for inside or outside stitching.
- 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 arranged at a lateral distance from one another and countersunk with respect to the broad side surface 26, which have an upper edge 47 curved in the transverse direction and with their outside Limit the adjacent edge-open recess 42.
- retaining tabs 50, 52 are bent downward in the central region, which reach down through two openings 54 of the base part 10 arranged at a distance from one another and which are provided with eyelets 56 in their lower region.
- Extending between the two retaining tabs 50, 52 is a leaf spring 58 made of plastic and aligned in the longitudinal direction of the base part 10, the ends of which extend through the eyelets 56 of the retaining tabs 50, 52 and are positively anchored by means of projections 60 on the lower edge of the eye.
- the leaf spring 58 is subject to a bending prestress, which is generated in the two end positions of the anvil plate 24 by means of a spherical latching cam 64 which bears against a transverse web 62 of the base part 10.
- a transverse locking rib 66 with an essentially triangular cross-section, against the run-up slopes of which the locking cam 64 of the leaf spring 58 rests in the respective end positions and which is overcome when the anvil plate 24 is moved by the locking cam 24 against the bending force of the leaf spring 58 must become.
- side guide surfaces 68 are arranged in the interior of the bottom part, against which the anvil plate 24 abuts with the outer edges of its retaining tabs 50, 52.
- the front tab 50 and the rear retaining tab 52 have different transverse dimensions, while the side guide surfaces 68 for the two retaining tabs 50, 52 have a different clearance from one another in pairs, so that it is ensured that the anvil plate can only be inserted into the base part 10 in the correct orientation.
- the invention relates to a stapler with an elongated base part 10, an upper part 14 pivotably mounted on a rear bearing block 12 of the base part and with an arranged in the front region of the base part 10, which can be displaced in the longitudinal direction in two end positions Deformation embossments 28, 30 for the legs of the anvil plate 24 provided with the ejected staples.
- a stapler with an elongated base part 10, an upper part 14 pivotably mounted on a rear bearing block 12 of the base part and with an arranged in the front region of the base part 10, which can be displaced in the longitudinal direction in two end positions
- Deformation embossments 28, 30 for the legs of the anvil plate 24 provided with the ejected staples.
- Pointing grip surfaces 40 having grip tabs 36 are integrally formed, on which the anvil plate 24 can be easily gripped between the thumb and index finger for adjustment.
