Publication number: 20100224382Abstract: A rotary power tool of the invention has a motor, a motor shaft driven by the motor, an output shaft coupled to the motor shaft via an automatic spindle locking mechanism, a housing portion surrounding the output shaft, and a braking member that is non-rotatable relative to the housing portion. The braking member exercises a braking torque on the output shaft whenever it rotates.Type: ApplicationFiled: May 30, 2008Publication date: September 9, 2010Inventors: Chi Hoe Leong, Yeo Joanne, Eng Hock Tan, Thomas Mathys, Olivier Zeiter, Daniel Brogli, Andreas Schwieger

Patent number: 7395874Abstract: A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part has a slaving unit fixable on the driving part fixed against relative rotation and having slaving claws that are offset from one another in a circumferential direction, a roller star wheel located in the slaving unit and connectable to the driven part fixed against relative rotation, clamping bodies located in freewheeling fashion between the slaving claws and points of a star of the roller star wheel, a stationary clamping ring located concentrically to the slaving means and the roller star wheel and having an inner annular face forming a counterpart clamping face for the clamping bodies, and radially displaceable centrifugal force elements located in the roller star wheel such that above a predetermined rpm the force elements clamp the roller star wheel firmly to the slaving means.Type: GrantFiled: November 14, 2005Date of Patent: July 8, 2008Assignee: Robert Bosch GmbHInventor: Olivier Zeiter

Patent number: 7287602Abstract: A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part has a slaving element fixable on the driving part and having slaving claws offset from one another in a circumferential direction, a roller star wheel connectable to the driven part and having points of a star offset from one another in the circumferential direction, and a stationary clamping ring located concentrically with the slaving element and the roller star wheel. A contact face on the points of the star is configured so that the clamping rollers, which when the slaving element is driven are pressed by the slaving claws against contact faces of the points of the star, are thrust inwards.Type: GrantFiled: November 14, 2005Date of Patent: October 30, 2007Assignee: Robert Bosch GmbHInventors: Olivier Zeiter, Bruno Aeberhard, Beat Salzgeber

Patent number: 6920695Abstract: A reciprocating hand saw (10), having a motor housing (16) and a gearbox (28) that receive a battery-operated direct-current motor (18) with a motor shaft having a shaft end (22) and a gear (28), respectively, which gear—as known per se in reciprocating saws—is connected to the shaft end in a way driven to rotate and whose gear input pinion (26) converts the rotation of the motor shaft end (22) into an up-and-down motion of a push rod (34) that carries a sawblade (38), can be produced economically and is especially sturdy because the gear (28) and its gearbox (14) originate in a reciprocating saw that can be operated by alternating current, and because between the shaft end (22) and the gear input pinion (26), a multi-stage coupling (24), disposed in a manner fixed against relative rotation for transmitting torque, comprises parts that can be easily separated from one another.Type: GrantFiled: January 31, 2003Date of Patent: July 26, 2005Assignee: Robert Bosch GmbHInventors: Olivier Zeiter, Daniel Saegesser
