Apparatus, system and method for controllable grappling hook

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 hook assembly comprising:
an upper assembly configured with a cap and pin for providing a location for attaching a thereto; a main body connected to said lower assembly for housing an actuator; a lower assembly connected to said main body, said lower assembly having a support structure body configured to have means for mounting a plurality of keeper arms thereto, a central bore for aligning said drive assembly with said actuator, and an end cap adapted to interact with said drive assembly; a clutch for connecting said drive assembly to said actuator assembly, said clutch being configured to limit a linear force applied to said actuator; and said drive assembly is configured to move a 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 support structure body by said means for mounting at a pivot point; said plurality of hook arms being connected to said drive assembly by one or more intermediate links, whereby when said actuator is energized said drive assembly rotates said hook arms to a closed position.
