Abstract
Official abstract text for this publication.
A stop mechanism for a drive system includes a one-way clutch, a brake, a stop feature, and a linkage. The one-way clutch couples with a drive shaft of the system when the drive shaft is rotating in a first direction but not in an opposite direction. The brake is connected to the drive shaft through the first one-way clutch and is operable to stop drive shaft rotation in the first direction. The stop feature is carried by an output element driven by the drive shaft and actuates the linkage to operate the first brake when the output element reaches a predetermined limit position when moving in a direction corresponding to the first drive direction of the drive shaft. A bidirectional stop mechanism is provided by adding a second one-way clutch, a second brake, and a second stop feature arranged to act in the opposite rotational direction of the drive shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A stop mechanism for a drive system having a motor, a drive shaft rotated by the motor, and an output element driven by rotation of the drive shaft, the stop mechanism comprising: a first one-way clutch for coupling with the drive shaft for rotation with the drive shaft when the drive shaft is rotating in a first drive direction but not when the drive shaft is rotating in a second drive direction opposite the first drive direction; a first brake connected…
