US Patent:

8556313, Oct 15, 2013

Filed:

Sep 16, 2011

Appl. No.:

13/234889

Inventors:

Brian M. Miller - Long Beach CA, US
John Cramer - Long Beach CA, US
David B. Lyon - San Diego CA, US
Eric J. Hostetler - Silverado CA, US
Bernard M. F. Welsch - Gardena CA, US

Assignee:

Force Multiplier, LLC - Huntington Beach CA

International Classification:

B66C 1/34

US Classification:

294 821, 294 8211

Abstract:

A retractable and fast-deploying grappling hook has a plurality of tines foldable around a central shaft that can quickly be individually set into a deployed position or a retracted position with no more than two turns of a capping head. The speed and ease of operation of the deploying and locking mechanism are due in part to the concavely machined undersurface of the head which mirrors the path end of the tines hinged to the side of the shaft. The same locking maneuver and adjustment of the head apply coincidentally to the deployed and retracted tines. A belt-attachable caddy houses a slotted receptacle for a removable plate mounting a take-up reel around which a cable secured to an eyelet at the proximal end of the shaft can be wound.

Abstract:

A belt-attachable caddy for carrying a retractable and fast-deploying grappling hook houses a slotted receptacle for a removable plate mounting a take-up reel around which a cable secured to an eyelet on the hook is wound. The hook has a plurality of tines foldable around a central shaft that can quickly be individually set into a deployed position or a retracted position with no more than two turns of a capping head. The speed and ease of operation of the deploying and locking mechanism are due in part to the concavely machined undersurface of the head which mirrors the path end of the tines hinged to the side of the shaft. The same locking maneuver and adjustment of the head apply coincidently to the deployed and retracted tines.
