Abstract: A stapler for stapling sheet material with staples, each staple having two staple legs and a staple crown. The stapler having an anvil arm, with a stapling unit being pivotable relative to the anvil arm and including a staple magazine receiving the staples and a driver for pushing staples through the sheet material, with a base part, on which the anvil arm is mounted movably towards it, and with two two-armed bending levers pivotably mounted on the anvil arm about a respective pivot axis, each bending lever having a first and a second lever arm. Upon approach of the anvil arm to the base part, the second lever arms are pivoted and bend the staple legs. The pivot axes extend substantially perpendicular to the staple crowns and the second lever arms have end portions which are arranged offset to one another in the axial direction of the pivot axes.

Abstract: The invention relates to a stapler (10) for stapling sheet material by means of staples (12), each staple (12) having two staple legs (14) and a staple crown (16) interconnecting the staple legs (14) and extending transversely to them, with an anvil arm (26) having a support plate (38) for placing the sheet material thereon, the anvil arm (26) carrying a cutting pad (40) with two cutting edges (42) for cutting off excess end parts of the staple legs (14), with a stapling unit (30) that is pivotally mounted relative to the anvil arm (26), which stapling unit (30) comprises a staple magazine (32) receiving the staples (12) in a row with the staple crowns (16) mutually abutting and being aligned parallel to each other and a driver (36) for pushing individual staples (12) with the free ends of their staple legs (14) first through the sheet material, with a base part (18), on which the anvil arm (16) is mounted movably towards it against a restoring force, and with two two-armed bending levers (50) pivotably mount

Abstract: Stapler (1) for driving staples (4) into a workpiece (6), comprising a body (2), an elastic member (7) connected to a driver (9) and an articulated arrangement (12) for tensioning of the member (7) comprising a lever (13) with a long arm (15) and a short arm (16) coupled rotatably to the body by a first coupling shaft (14), an articulated arm (17) coupled rotatably to the body by a second coupling shaft (18) and connected to the member (7) in a force-influencing manner, an intermediate joint (19) with a third coupling shaft (20) assigned rotatably to the short arm (16) at a first distance (a) from the first coupling shaft and assigned rotatably to the articulated arm (17) with a fourth coupling shaft (21) at a second distance (b) from the third coupling shaft (20), the first distance has the distance line (a) and the second distance has the distance line (?), which form the angle (?) between themselves, the member (7) is tensioned in that the lever (13) is rotated (N) about coupling shaft (14) from a starting
