Patent number: 10525541Abstract: A transmission device is configured to generate at least one of a stroke motion and a reciprocating motion of an insert tool of a hand-held power tool, and includes at least one link unit configured to generate the stroke motion. The link unit includes at least one output element, at least one link element, at least one contact surface, and at least one further contact surface. The at least one contact surface is disposed at least partially on the at least one output element. The at least one link element is configured to act in combination with the at least one output element via the at least one contact surface. The at least one further contact surface is configured to generate a force that initiates the reciprocating motion, and is disposed at least partially on the at least one output element.Type: GrantFiled: December 13, 2016Date of Patent: January 7, 2020Assignee: Robert Bosch GmbHInventors: Daniel Saegesser, Michael Laett
