摘要： A ramp assembly for installation in a vehicle includes a ramp platform having a stowed configuration in the vehicle, a deployed configuration extending from the vehicle, and a lift and lock mechanism. The lift and lock mechanism is configured to lock the ramp platform in place when the platform is in a stowed configuration and to facilitate the lifting of the platform when the platform is deployed.

摘要： One embodiment is directed to a locking mechanism. The locking mechanism has a housing and a rotary actuator carried by the housing. The rotary actuator includes a shaft and armature disposed around at least a portion of the shaft. The armature is configured to rotate the shaft about a longitudinal axis of the shaft. The locking mechanism also has a cam carried by the shaft and a set of locking balls disposed between the cam and the housing. The locking mechanism has a locking assembly carried by the housing, the locking assembly being axially positionable between a locked position relative to the housing and a released position relative to the housing.

摘要： A clutch-driven limited force actuator is disclosed having a motor, a planetary gear mechanism in operative communication with the motor and a clutch plate. The clutch plate includes a contact surface selectively in frictional contact with the planetary gear mechanism to drive an actuator arm. In operation, the frictional force between the planetary gear mechanism and the clutch plate causes the actuator arm to actuate. The actuator arm can be connected to any element that requires actuation. The actuator of the present invention is preferably used in a wheelchair lift to actuate any mechanism that must have a safe limit on the amount of force applied to obstacles and that must have provision for direct manual operation.
摘要翻译：公开了一种离合器驱动的限制力致动器，其具有电动机，与电动机和离合器板可操作地连通的行星齿轮机构。离合器板包括选择性地与行星齿轮机构摩擦接触以驱动致动器臂的接触表面。在操作中，行星齿轮机构和离合器片之间的摩擦力使致动器臂致动。执行器臂可以连接到需要启动的任何元件。本发明的致动器优选地用于轮椅升降机中以致动任何必须对施加到障碍物上的力的安全限制的机构，并且必须具有用于直接手动操作的设备。
