Force multiplying retaining straps

Abstract

A generally U-sectioned cam buckle frame is modified to include a first turning roller aligned transversely across the frame proximate the free end of a release lever. A generally planar tongue having one end pivoted adjacent the first roller extends within the frame under the cam piece connected to the release lever provides a force transfer structure for a strap is inserted between the tongue and the frame bottom surface, around the first roller to pass between the cam piece and the other side of the tongue. Other transverse rollers may be included in the frame to form a pulley arrangement and one end of a frame side wall may be convolved to form a hook assembly.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 12 / 802,845 filed on Jun. 15, 2010 which, in turn, obtains the benefit of the earlier filing date of US Provisional Application Ser. No. 61 / 338,993 filed on Mar. 1, 2010 and the benefit of this earlier filing date is claimed for all matter common therewith.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to motorcycle transport restraints, and more particularly to restraining strap clasping mechanisms combined with pulley pivots for increasing the force levels obtained from the combination.[0004]2. Description of the Prior Art[0005]The outdoor recreation customs and habits that have developed here in the United States adapted to the grandiose and large landscapes of the country, with a consequent reliance on all sorts of motorized vehicles that either bring us closer to nature, as for example the motorcycle, or are speciali...

AI Technical Summary

Benefits of technology

"The present invention is a single piece frame cam buckle assembly for multiple loop load multiplication. It includes a plurality of transverse pivot rollers bridging across the frame, a manually articulated eccentrically pivoted interlock, and a longitudinally projecting hook for added load transfer and to retain tie-down strapping. The assembly can be used in a complementing manner with another pulley assembly to effectively perform any restraining or release. The technical effects of the invention include increased load carrying capacity, simplified restraining sequence, and increased safety features."

Problems solved by technology

These restraints often require very large tension levels, particularly when robust suspension elements need to be controlled.

Thus while suitable for the purposes intended, the need for a wind-up mechanism and a lever dimension necessary to produce the desired level of force limits the usefulness thereof in the cramped surroundings associated with an articulated lifting assembly.

Simply, the space that is cluttered by the components of an articulated lifting mechanism leaves little accommodation for any fixed wind-up mechanisms, operated by levers and the like, particularly when variously shaped carried vehicles are entailed.
