| 发明名称 | Low energy clutch for electronic door lock | ||
| 摘要 | A clutch for an electronic door lock includes a primary mover, a pivotal pawl, a first shaft, and a second shaft. The second shaft is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft. The primary mover is selectively actuatable to engage the pawl such that rotation of the first shaft relative to the second shaft by a user pivots the pawl into coupling engagement between the first shaft and the second shaft. | ||

| 主权项 | 1. A drive clutch for an electronic door lock, the clutch comprising: a rotatable first shaft having a movable mechanism coupled thereto; a second shaft axially co-aligned with and rotatably disposed adjacent the first shaft; a pivotal pawl rotatably coupled to the second shaft; and a prime mover selectively actuatable to eliminate a clearance between the movable mechanism and the pivotal pawl such that rotation of the first shaft relative to the second shaft by a user causes the movable mechanism to engage the pawl to pivot the pawl into coupling engagement between the first shaft and the second shaft. | ||
