Abstract
Abstract A harnessing device formed by a locking head and an attached webbed strap. The head contains oppositely positioned locking tangs in a guide channel that receives the strap after encirclement of items to be harnessed. The tangs engage abutments of the webbed strap for adjustable retention of the harnessed items. The strap is advantageously molded of a stretch reorientable material. Stretching produces a relatively thin and strengthened web which resists penetration by the locking tangs and reduces the possibility of failure by fracture or reverse rotation. The inclusion of the relatively thin web also promotes homogeniety during molding and avoids imperfections that can cause failure in other types of straps.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A harnessing device comprising a head having an elongated guide channel extending therethrough, a pair of deflectable locking tangs within said head, and a strap formed by a ladder structure with rungs which are sequentially engaged by the locking tang when the strap is inserted into the channel, said ladder structure having a webbed portion substantially constant thickness extending from each rung to reduce the force for insertion of said strap into said channel and to limit the effect of reverse thrust applied to said strap in causing reverse rotation of said locking tang.
Claim 2
Dependent Claim
94 words
A harnessing device comprising a head having an elongated guide channel extending therethrough, a pair of deflectable locking tangs within said head, and a strap formed by a ladder structure with rungs which are sequentially engaged by the locking tang when the strap is inserted into the channel, said ladder structure having a webbed portion substantially constant thickness extending from each rung to reduce the force for insertion of said strap into said channel and to limit the effect of reverse thrust applied to said strap in causing reverse rotation of said locking tang.
Claim 3
Dependent Claim
80 words
A harnessing device as defined in claim 1 wherein said device is molded from a stretch-reorientable material and the webbed portions of said strap is characterized by having permanent molecular reorientation caused by stretching, thereby to realize a relatively thin and strengthened member extending from each rung of said ladder for reducing the force required for insertion of said strap into said channel and limiting failure of said locking tang by rotation due to reverse thrust applied to said strap.
Claim 4
Dependent Claim
23 words
A harnessing device as defined in claim 1 wherein each rung of said ladder strap includes abutments for engagement by said locking tangs.
Claim 5
Dependent Claim
39 words
A harnessing device as defined in claim 1 wherein said webbed portion extends from one rung to another, thereby to permit the load applied to one of said rungs by said locking tang to be distributed among other rungs.
Claim 6
Dependent Claim
52 words
A harnessing device as defined in claim 4 wherein said webbed portion further extends between adjoining rails of said ladder strap, thereby to distribute the load applied by a locking tang in engagement with a rung of said strap among not only adjoining rungs but the associated structure thereof of said strap.
Claim 7
Dependent Claim
39 words
A harnessing device as defined in claim 1 wherein one end of said strap is attached to said head at an angle with respect to the axis of insertion of the other end of said strap to said channel.
Claim 8
Dependent Claim
27 words
A harnessing device as defined in claim 1 wherein each of said locking tangs has a tip that is proportioned to mate with abutments in said rung.
Claim 9
Dependent Claim
83 words
A harnessing device as defined in claim 1 wherein said locking tangs are integrally connected within said head by a neck portion which is narrower than the extension of said locking tangs into said channel, thereby to facilitate the insertion of said strap into said channel, and said extension of said locking tangs form an angle no greater than 30° with respect to the axis of said channel, thereby to increase the resistance of said locking tangs to failure and reverse thrust rotation.
