  • Patent number: 8656598
    Abstract: A handheld jigsaw, such as a compass saw (10), is disclosed that comprises a housing (12, 13) and a lifting rod (20) having a pendulum mechanism (38). The pendulum mechanism includes a pendulum lever (40) with which a pendulum stroke can be given during sawing to a saw blade (28) carried by the lifting rod (20). The lifting rod (20) is arranged such that it can rotate about its own axis (21) thereof and pivot transversely to the axis (21), and wherein the pendulum mechanism (38) can rotate about the axis (21).

  • Patent number: 8024865
    Abstract: The invention relates to a clamping device (8) for connecting a saw blade (12) to a reciprocating rod (6) of a jig saw, in particular a hand-operated compass saw (2), comprising a mounting (20), which is connected to the reciprocating rod (6) and has a recess (22) for receiving a head end (10) of the saw blade (12), a locking sleeve (30), which can be turned about the axis (40) with respect to the mounting (20) against the force of a torsion spring (60) to lock the head end (10) of the saw blade (12) in a locking position in the recess (22) and to allow removal of the saw blade (12) in a removal position. It is intended that a stop (78) interacts with a part (80) of the torsion spring (60), in order to prevent movement of the locking sleeve (30) beyond the removal position.

  • Publication number: 20110131820
    Abstract: The invention relates to a hand-held jigsaw, especially a compass saw, having a housing and a lifting rod with a pendulum mechanism, especially a pendulum lever, with which a pendulum stroke can be given during sawing to a saw blade carried by the lifting rod, especially a jigsaw blade. According to the invention, the hand-held jigsaw can be used more safely and in more special applications as the lifting rod is arranged such that it can rotate about the axis thereof and pivot transversely to the axis, and the pendulum mechanism can rotate about the axis.

  • Publication number: 20080222901
    Abstract: The invention relates to a handheld hacksaw with a saw blade that can be moved to and fro, an effective support device (20) in the direction of sawing, with a support element (21) that supports the back of the saw blade, a holder (22) that holds the support element (21) between two sides (222, 223), and guide elements (26, 27) with facing guide surfaces (261, 271) on the two sides of the saw blade facing away from each other. To reduce the production costs for the handheld hacksaw by ensuring a simple design of the guide elements adequate for high-quality sawing, the guide elements (26, 27) have a fixed horizontal spacing of the guide surfaces (261, 271) thereof, perpendicular to the direction of sawing at the ends of the sides (222, 223) of the holder (22).
