WIRELESS CONTROLLABLE CAROUSEL INDEPENDENTLY RELEASABLE GRAPLING HOOKS

摘要

The present invention a controllable hook assembly having a structurally connected main body portion between upper and lower assemblies. The main body encloses actuator that connects by a clutch to drive assembly disposed in the lower assembly whereby the clutch is configured to limit the connection to a predetermined linear force applied to the actuator. The drive assembly is configured to move a plurality of hook arms between an open and closed position and is adapted capturing a line attached to a load. A controller interacts with the actuator to energize a motor and gearbox to provide linear motion and drive an actuator output shaft against the drive assembly, whereby when the actuator is energized the linear motion of the actuator output shaft moves the hook arms between an open and a closed position.

1. A grappling hook apparatus comprising:
a main body structure with a means for attaching or suspending the grappling hook; a plurality of hook arms, pivotally connected to said main body structure; an actuator, mounted to said main body structure, operably coupled to said hook arms; said actuator comprising one or more motors cooperating with a screw shaft to rotate said screw shaft; said screw shaft cooperating with a correspondingly threaded member such that when said screw shaft rotates by energizing said motors, said threaded member moves up or down said screw shaft; said threaded member coupled to said plurality of said hook arms by one or more links, whereby when said actuator is energized, said threaded member moves up or down said screw shaft, rotating said plurality of hook arms between an open and closed position adapted capturing a line attached to a load, said plurality of hook arms being connected to said main body structure by said means for mounting at a pivot point of said plurality of hook arms.
