Mechanical lock with a cam-driven locking pawl |
摘要 |
A rack mounted within the housing of a mechanical lock translates. The rack, which has a rectangular cross-section, has teeth along one surface. A toothed pawl pivots housing between a locked and unlocked position. The teeth on the pawl engage the rack teeth when the pawl is locked. The pawl has a window that receives a cam. The cam has a first surface that engages a surface of the window when the cam is in the locked position. In that position, the cam prevents pawl movement teeth away from the teeth on the rack. A second surface of the cam pushes against a different surface of the window when the cam is in the unlocked position. In that position, the cam disengages the pawl teeth from the rack teeth. The window has a chamfered surface to move the pawl to its locked position.
