  • Patent number: 11919134
    Abstract: A tool having a working piston that moves along a working axis, a drive, for driving the working piston along the working axis, the drive having an electrical capacitor, a squirrel-cage rotor arranged on the working piston and an excitation coil, wherein current flows through the coil during rapid discharge of the capacitor and generates a magnetic field that accelerates the working piston, the tool having a frame of a soft-magnetic and electrically conducting material surrounding the excitation coil and extending in a circumferential direction with respect to the working axis, the frame having one or more at least partial interruptions, which extend over a significant part of a radial extent of the frame with respect to the working axis.

  • Publication number: 20220072690
    Abstract: An apparatus driving fastening elements has an energy store, a transmission element movable along a setting axis in a driving direction between a starting position and a setting position for transmitting energy from the energy store to the fastening elements, the transmission element having a rear end in the driving direction, the energy store having a container and a piston, the container defining a cylinder axis and the piston being movable along the cylinder axis in the container, the piston closing off a partial volume of the container, and gas in the closed-off partial volume forming a gas spring, the apparatus having a force transmission device transmitting a spring force of the gas spring to the rear end of the transmission element, the rear end of the transmission element being arranged behind the piston in the driving direction when the transmission element is in the starting position.

  • Publication number: 20200298386
    Abstract: An apparatus for driving a fastening element into an underlying surface, the apparatus having a center of gravity, an energy transmission element, which is movable between a starting position and a setting position, for transmitting driving-in energy to the fastening element, a piston drive that provides driving-in energy, a housing, and a bolt guide that guides the fastening element while it is being driven in, wherein the bolt guide is mounted on the housing in a rotatable manner with respect to rotation about the center of gravity.

  • Publication number: 20200030955
    Abstract: A hand-held tool comprises a housing with a neck-like housing portion and a suspension element with a connection portion for connecting the suspension element to the neck-like housing portion and with a suspension portion for temporarily suspending the tool on a separate object, wherein the connection portion has two spring arms, which enclose the neck-like housing portion on opposite sides in a snap-fit connection in order to connect the suspension element to the housing.

  • Publication number: 20180257209
    Abstract: A hand-held drive-in device for fastening elements has a drive arrangement for a drive-in ram which is mounted so as to be movable in a guide, the ram being coupled via a transmission device to at least one drive spring element which can be tensioned via a tensioning device, wherein the transmission device and the drive spring element have masses. In order to improve the quality of setting operations, the masses of the transmission device and of the drive spring element are tailored to one another such that, when driving a fastening element at a drive-in point into a substrate, the hand-held drive-in device experiences a supporting force which acts in the direction of the substrate and serves, with the hand-held drive-in device, to exert pressure on the surroundings of the drive-in point.

  • Publication number: 20170341211
    Abstract: The invention relates to a nail device for setting nails into an object, comprising a housing, a setting mechanism for setting the nail along a setting axis, a bolt-guiding element for contacting on the object at a first contact point, in particular a trigger for activating the setting mechanism, a swivelable support foot for contacting on the object at a second contact point, wherein a connecting line between the first and the second contact point and the setting axis span a device plane of the nail device, characterised in that the swivel axis of the support foot is oriented substantially perpendicular to the device plane.
