Abstract
Abstract A rope tie down clamp which employs a dual pin arrangement upon which the rope is wound, the arrangement being such that in use the tie down force being transmitted through the clamp is substantially lineal, the dual pin arrangement causing the rope to frictionally bind upon itself during use, release of the clamp being effected by movement of the clamp housing in a particular direction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A tie down clamp to operate between a first object and a second object, said tie down clamp comprising: a housing; a first pin fixed to said housing, a second pin fixed to said housing and spaced from said first pin, a third pin fixed to said housing and spaced from both said first pin and said second pin, said third pin being pivotally connected to said first object and located a fixed spacing relative to said first pin, the spacing of said second pin from said third pin being greater than the spacing of said first pin from said third pin, a rope to contact said first pin over a first portion of said rope and then be wound about said second pin, the free end of said rope is then conducted again about said first pin to produce a second rope portion in contact with approximately said first portion, said free end of said rope connected to said second object and the other end of said rope receiving a tie down force to be effected between said first object and said second object resulting in the rope being forced together in friction engagement with itself over said portion about said first pin; the line between said first and second pins forming a substantial acute angle with a line passing through said second and third pins.
Claim 2
Dependent Claim

A tie down clamp to operate between a first object and a second object, said tie down clamp comprising: a housing; a first pin fixed to said housing, a second pin fixed to said housing and spaced from said first pin, a third pin fixed to said housing and spaced from both said first pin and said second pin, said third pin being pivotally connected to said first object and located a fixed spacing relative to said first pin, the spacing of said second pin from said third pin being greater than the spacing of said first pin from said third pin, a rope to contact said first pin over a first portion of said rope and then be wound about said second pin, the free end of said rope is then conducted again about said first pin to produce a second rope portion in contact with approximately said first portion, said free end of said rope connected to said second object and the other end of said rope receiving a tie down force to be effected between said first object and said second object resulting in the rope being forced together in friction engagement with itself over said portion about said first pin; the line between said first and second pins forming a substantial acute angle with a line passing through said second and third pins.
Claim 3
Dependent Claim
30 words
A clamp as defined in claim 1 wherein: having a member fixed to said housing adjacent said second pin for rotating said housing about the axis of said third pin.
Claim 4
Dependent Claim

A clamp as defined in claim 1 wherein: said line located between said second pin and said first pin forming an angle of approximately 90* with the direction of said tie down force substantially defined by a line located between said third pin and said first pin with a line located between said third pin and said first pin.
Claim 5
Dependent Claim
16 words
Apparatus as defined in claim 1 wherein: said housing comprises a paiR of spaced apart plates.
