Patent number: 8950508Abstract: A handheld power tool, including a tool socket on a drive shaft for purposes of holding a tool, the drive shaft executing a rotating and partially tangentially striking movement using a tangential striking mechanism drivable by a drive. The tangential striking mechanism has an anvil associated with the drive shaft and a hammer associated with the drive, movable with respect to each other so as to strike each other axially when under the effect of the force of at least one first spring, and to strike each other tangentially when the anvil and the hammer are rotated. The hammer has a main mass, and an extra mass that is under the effect of a second spring couplable to the main mass.Type: GrantFiled: November 25, 2011Date of Patent: February 10, 2015Assignee: Hilti AktiengesellschaftInventors: Alexander Hoop, Hans Boeni, Dieter Profunser, Peter Brugger

Publication number: 20080289839Abstract: In a method for controlling a drive (4) of an electrically operated screwdriving power tool (2) during a screwdriving process, a tool holder (14) with a screw bit (16) fastened thereto is acted upon by the drive (4) to drive a fastening element (18) having a contact area (24) into a constructional component (20), with the screw bit movable up to a maximum screw-in value (Dmax) at a speed (D) and a operational torque (MA) generated between the screw bit (16) and the fastening element (18), and after it has been detected that a predetermined triggering screw-in depth (s0) has been reached, the speed (D) is reduced from the maximum screw-in value (Dmax) during a tightening process (AV), and, when it has been detected that a determined end value of the operational torque (MA) is reached, the screwdriving process is terminated.Type: ApplicationFiled: May 19, 2008Publication date: November 27, 2008Inventors: Peter Hricko, Alexander John, Hans Boeni, Peer Schmidt, Jochen Kuntner

Patent number: 6640205Abstract: The method of and a device for using this method, on equipment or assigned to equipment for working a material, for investigating and identifying the nature of the material, which is to be worked and for making available at least one operating parameter for the optimized pre-setting of the working equipment, provides for the use of a sensor, preferably assigned directly to the working tool, such as a hammer drill, in order to detect shock waves generated or induced in the tool. From the shock wave signal measured, at least one distinguishing feature characteristic of the material to be worked, is extracted and evaluated for the comparative classification of the material by means of an algorithm. Preferably, an external force, especially the contacting force, acting on the working equipment, is taken into consideration for the algorithmic evaluation.Type: GrantFiled: December 12, 2000Date of Patent: October 28, 2003Assignee: Hilti AktiengesellschaftInventors: Hans-Werner Bongers-Ambrosius, Roland Schaer, Hans Böni, Harald Schmitzer

Patent number: 4389870Abstract: In the formation of engagement grooves in the shank of a tool for use in a hammer drill or chipping hammer, a matrix or die is divided along a junction plane into two matrix halves. A bore for holding the tool to be punched is formed along the junction plane so that the plane divides the bore in half in its axial direction. Guide openings are formed in the opposite sides of the matrix extending into the bore for receiving punching dies. The matrix halves combine to form these guide openings which are located in the junction plane so that the punching pressure is applied in this plane. The closing pressure for holding the matrix halves together is applied at right angles to the junction plane.Type: GrantFiled: April 23, 1981Date of Patent: June 28, 1983Assignee: Hilti AktiengesellschaftInventors: Hans Boeni, Beda Meier, Gabor Szacsvay
