  • Patent number: 11673245
    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.

  • Patent number: 9919408
    Abstract: Staple gun for driving staples into a workpiece includes a frame with a driver conveyable upward and downward. In the downward movement, the driver executes a drive stroke driving the staple. In the upward movement, an activation member conveys the driver to a highest height and releases the driver to execute the drive stroke. An elongated elastic member has a first end coupled to the driver and a second end to a bearing pin assigned to the frame. A first breakpoint pin is placed between the bearing pin and the driver at a first distance from the bearing pin, and a second breakpoint pin between the driver and the first breakpoint pin is arranged at a second distance from the bearing pin and is movable between first and second positions disengaging and engaging the elastic member, respectively. The first distance is related to the highest height as 1.6-2.0:1.

  • Patent number: 7621433
    Abstract: Stapler (1) which comprises a base part (2) and a stapling unit (3). The base part consists of a lower part (5) and an upper part (6) which are connected together such that they from each other, and between which parts is arranged a first elastic element (8) which, in an initial position, moves the upper and lower parts apart. A workpiece to be stapled is placed on the upper part (6), where an opening (31) is arranged through which the legs of the staple is driven after that the legs have driven through the workpiece, and to which upper part bending devices (21, 22), pivotable about pivot pins (25, 26), are connected. The upper part being blocked from moving downward by a blocking arrangement (21, 22, 25, 26, 44, 45) when the driver drives the staple legs through the workpiece. The blocking device is disengaged by means of a releasing device (53, 54, 55, 56) when the staple crown (40) contacts the upper surface (17) of the workpiece.

  • Patent number: 7614537
    Abstract: A stapler comprises a stapling unit and a base movably connected to each other. The base comprises an anvil, a lower and an upper part with a contact surface which has a staple opening against which a workpiece is placed. The upper and lower parts are movably connected to each other. In operation, movement of the stapling unit and the base toward each other drives a staple into the workpiece, wherein the staple crown comes in contact with the workpiece and the staple legs extend through the staple opening. Upon movement of the upper part and stapling unit toward the lower part, the staple legs are bent by the anvil into contact with the underside of the workpiece. The anvil is attached to the base by an elastic element between the lower and upper part, and is urged toward the staple opening to block the opening when the stapler is in an initial position.
