Abstract: Stapler by which a workpiece, preferably a sheaf of papers, is stapled together, which stapler includes a base part, to which is arranged a solid anvil, and a stapler head which base part and stapler head is with a connecting device connected to each other such that they relative each other can be moved in a reciprocating stapling movement in which movement the workpiece is stapled and which movement includes a forward direction which ends at a first turning point in which the stapler head contacts the anvil and a return direction, in which the stapler head is moved away from the anvil, and which ends in a second turning point wherein the anvil is such arranged that it is elastically yielding in the direction away from the first turning point.

Abstract: A stapler has a drive train that drives a stapling head toward a base part in a driving stroke and away from the base part in a return stroke. To accommodate thick workpieces to be stapled, without jamming, the drive train includes a coupling constructed so that its effective connection between coupled parts is releasable and so that it loses its effective connection during the driving stroke to prevent jamming.

Abstract: Stapler (1) which in the course of a reciprocating working stroke (V) staples a workpiece (4), preferably a sheaf of papers, which stapler is powered by an electric motor which, via a transmission arrangement (5) drives the stapler during the working stroke, whereby the motor is activated and initiates the working stroke from a certain starting region as a result of the workpiece moving a trigger (32,33) which forms part of a trigger device (6) to a position at which a circuit-breaker (7), which forms part of the same electrical circuit (8) as the motor is connected to, is closed by the trigger, and whereby a release arrangement (9) connected to, and operatively acted upon, by a rotating means (11) which forms part of the transmission arrangement moves the trigger during the return phase of the working stroke to a non-closing position at which the circuit-breaker returns to an open position, thereby breaking the electric circuit and deactivating the motor, with the result that the working stroke ends in the s

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.

Abstract: Circuit-breaker arrangement (32) in an indicating arrangement (33) forming part of an electrically powered stapler (1). The stapler comprises a stapling head (2) and an anvil (3). The stapling head comprises an interchangeably fitted staple cassette (5) containing staple blanks (36), and the indicating arrangement. The circuit-breaker arrangement is so positioned that it is moved by the staple cassette from a first to a second position when the staple cassette is fitted to the stapling head and when the power supply via the indicating arrangement changes. The circuit-breaker arrangement (32) comprises an input line (22) and output line (23), of which at least the input line is dimensionally stable and resiliency flexible.

Abstract: A stapler (1) for stapling a workpiece (5), especially a sheaf of papers, which stapler comprises a base part (2) and a stapling head (3) which are connected together by a connecting means (4) in such a way that they can move towards and away from one another in a reciprocating stapling movement (P) which has a first turning point (FIG. 1) and a second turning point (FIG. 3), which stapling head accommodates staples (14) and a driver (7) which is supported for sliding in the direction of the stapling movement and which during the course of the stapling movement drives a staple into the workpiece which is to be stapled, and said stapler also comprises a drive means (13) which, in the course of a driving stroke (N) which forms part of the stapling movement, starting from a point at which the stapling head and the base part are at a distance from one another, drives the stapling head and the base part towards one another to the second turning point (FIG.

Abstract: A stapler (1) for stapling together a workpiece (5), primarily a sheaf of papers, which stapler comprises a stapling unit (3) and a base part (2) which, by means of a connecting device (4), are connected in such manner that they can be moved toward and away from each other in a reciprocating stapling movement (P), wherein the stapling unit contains staples (8) and a driver (7) and the base part comprises a lower part (9) and an upper part (25) provided with a contact surface (26) provided with a staple opening (27) against which the workpiece to be stapled is placed during the stapling, wherein the upper part is connected to the lower part in such manner that it can be moved toward and away from the lower part during the stapling movement, wherein a latching arrangement (15, 28) is provided between the lower part and the upper part to prevent the upper part from being moved toward the lower part and wherein an anvil device (22) is arranged on the base part, wherein stapling is performed by moving the stapling
