| 20090023371 | Power-Driven Hand Tool - A power-driven hand tool comprises a drive spindle adapted to drive a tool, that can be driven to oscillate about its longitudinal axis, which tool can be fixed on a retaining section of the dive spindle by a securing element, and further comprises a displacing device that serves to displace the securing element between a releasing position in which the securing element can be released from the drive spindle and a clamping position in which the securing element is clamped on the retaining section by a spring element, the securing element comprising a clamping shaft adapted to be inserted into the securing element, which is axially fixed in the drive spindle for clamping the tool in the clamping position, and which can be detached in the releasing position. For clamping of the tool a split chuck is provided which is clamped on the retaining section by the securing element in the clamped position and is connected with the retaining section in form-locking engagement. | 01-22-2009 |
| 20100009613 | Tool Having A Mounting Opening For Positive Connection To Different Drive Shafts - A tool is disclosed having a mounting opening for positive connection to a drive shaft that can be driven oscillatingly, the mounting opening comprising a plurality of outwardly extending projections each having an outer convex section that ends on both sides in concave lateral flanks, with neighboring lateral flanks joining each other on their way toward the center axis of the mounting opening to form a common bulge, concave on the outside, the shape of the outwardly extending projections, of the lateral flanks and of the bulges being such that there can be effected, optionally, either a positive connection to a first raised securing section of a first drive shaft, having a plurality of outwardly extending convex raised portions each having a rounded tip and rounded concave lateral flanks, or, optionally, a positive connection to a second securing section of a second drive shaft, having a plurality of raised positive-connection elements arranged in regular intervals on a circular line. | 01-14-2010 |
| 20100197208 | Power-Driven Hand Tool With Clamping Fixture For A Tool - A power-driven hand tool is disclosed comprising a housing, a work spindle for driving a tool, which tool can be located between a tool end of the work spindle and a fixing mechanism, further comprising a displacing mechanism with a clamping lever, adapted to pivot about a pivot axis for displacing the fixing mechanism between a releasing position, in which the fixing mechanism can be released from the work spindle, and a clamping position in which the fixing mechanism is clamped on the work spindle by a spring. An impeding mechanism is provided that interacts with the clamping lever for impeding the pivoting movement of the clamping lever between the releasing position and the clamping position. | 08-05-2010 |
