    • A lock mechanism has a housing and a latch extending from the housing. The latch has an extended position and a retracted position. The mechanism includes apparatus for biasing the latch to the extended position, apparatus for defining a locked mode and an unlocked mode, and apparatus including a clutch for transferring an operator input motion to move the latch to the retracted position in the unlocked mode. The clutch includes a cam surface and a cam follower. A spring biases the cam follower toward the cam surface and a second override spring which biases the cam follower to compensate for any off-center relationship due to wear, excessive force and/or assembly misalignment and to prevent jamming.
    • 锁定机构具有从壳体延伸的壳体和闩锁。 闩锁具有延伸位置和缩回位置。 该机构包括用于将闩锁偏压到延伸位置的装置,用于限定锁定模式和解锁模式的装置,以及包括用于传递操作者输入运动的离合器的装置,以在未锁定模式下将闩锁移动到缩回位置。 离合器包括凸轮表面和凸轮从动件。 弹簧将凸轮从动件偏压到凸轮表面,以及第二倍频弹簧,其偏置凸轮从动件以补偿由于磨损,过大的力和/或组装不对准而导致的任何偏心关系并且防止卡住。

    • An electronic combination lock is disclosed which allows access to a closed or secure location wherein the lock includes a locking mechanism for operating between a locked condition and an unlocked condition. A rotatable cam wheel has a circumferential surface portion defining a slot such that rotation of the cam wheel moves the slot. A movable lever is coupled to the locking mechanism for changing the condition of the locking mechanism from the locked condition to the unlocked condition and is pivotably movable into and out of engagement with the cam wheel. The movable lever engages the cam wheel such that rotation of the cam wheel changes the condition of the locking mechanism. A cantilever and detent on the lever releasably maintain the lever in a position disengaged from the cam wheel. A solenoid and projectable detent moves the lever from its disengaged position for engaging the lever with the cam wheel so that rotation of the cam wheel changes the locking mechanism from the locked condition to the unlocked condition.
    • 公开了一种电子组合锁,其允许进入关闭或安全的位置,其中锁包括用于在锁定状态和解锁状态之间操作的锁定机构。 可旋转的凸轮具有限定槽的圆周表面部分,使得凸轮的旋转使狭槽移动。 可动杆联接到锁定机构,用于将锁定机构的状态从锁定状态改变到解锁状态,并且可枢转地移动进入和离开与凸轮的接合。 可动杆接合凸轮,使得凸轮的旋转改变锁定机构的状态。 杠杆上的悬臂和棘爪可释放地将杠杆保持在与凸轮相脱离的位置。 螺线管和可投射式制动器将杠杆从其脱离位置移动,以将杠杆与凸轮相接合,使得凸轮的旋转将锁定机构从锁定状态改变到解锁状态。
