Patent number: 9221165Abstract: A tool receptacle is disclosed. The tool receptacle has a spindle which has a receiving area for receiving a tool and an elongated hole which is open into the receiving area in a radial direction. A barrier element disposed in the elongated hole projects into the receiving area and is movable in the elongated hole. A slider is used for sliding the barrier element to an output-side end of the elongated hole, where the slider is subject to the application of force by a first spring against an insertion direction. A radial limit stop forces the barrier element in the radial direction to engage in the receiving area. The radial limit stop is displaceable to enable a radial movement of the barrier element out of engagement with the receiving area. A second spring applies a spring force to the radial limit stop against the insertion direction.Type: GrantFiled: June 8, 2012Date of Patent: December 29, 2015Assignee: Hilti AktiengesellschaftInventors: Aaron Wiedner, Markus Hartmann, Udo Hauptmann
