Abstract
Abstract A harnessing device formed by a locking head and an attached ladder strap. The head contains a locking tang and a guide channel that receives the strap after encirclement of items to be harnessed. The tang engages the rungs of the ladder strap for the adjustable retention of the harnessed items. The free end of the strap has a light-weight webbed tail that facilitates the insertion of the strap into the head. The strap is advantageously molded of a stretch reorientable material and is subsequently stretched to produce a suitable strengthening and elongation of the webbed tail.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
A harnessing device comprising a head having an elongated guide channel extending therethrough, a locking tang within said head, and a strap formed by a structure with members which are sequentially engaged by the locking tang when the strap is inserted into the channel, said strap having a webbed tail portion flanked by side rails which extend from said members continuously surrounding said webbed portion and forming an angle with said strap.
Claim 2
Dependent Claim
72 words
A harnessing device comprising a head having an elongated guide channel extending therethrough, a locking tang within said head, and a strap formed by a structure with members which are sequentially engaged by the locking tang when the strap is inserted into the channel, said strap having a webbed tail portion flanked by side rails which extend from said members continuously surrounding said webbed portion and forming an angle with said strap.
Claim 3
Dependent Claim
21 words
A harnessing device as defined in claim 1 wherein said members which are sequentially engaged by said locking tang comprise rungs.
Claim 4
Dependent Claim
30 words
A harnessing device as defined in claim 1 or claim 2 wherein said side rails extend along said strap adjoining said members which are sequentially engaged by said locking tang.
Claim 5
Dependent Claim
57 words
A harnessing device as defined in claim 1 or 2 wherein said device is molded from a stretch-reorientable material and the webbed portion of said strap is characterized by having permanent molecular reorientation caused by stretching, thereby to realize a relatively thin and strengthened member extending between the edges of said strap at the tail portion thereof.
Claim 6
Dependent Claim
41 words
A harnessing device as defined in claim 1 wherein said strap includes rungs which are engageable with said locking tang and the length of said tail portion is at least equal to the interval between two successive rungs of said strap.
Claim 7
Dependent Claim
22 words
A harnessing device as defined in claim 1 wherein said side rails extend substantially parallel over a region of said tail portion.
Claim 8
Dependent Claim
41 words
A harnessing device as defined in claim 1 or 2 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 9
Dependent Claim
16 words
A harnessing device as defined in claim 1 or 2 wherein said locking tang is deflectable.
