Abstract
Abstract A cable tie comprises a strap having a plurality of spaced parallel racks of teeth extending along the length thereof and a head for receiving the strap. A reinforcing median strip extends along the length of the strap between the racks of teeth to add material thickness, and mechanical strength to the strap. A bifurcated pawl is included in the head so that a separate pawl engages each rack of teeth. The teeth in each rack are in substantial, contiguous alignment. The teeth in the pawls are also in substantial, contiguous alignment for engaging the teeth of the strap. The median strip guides and directs the pawls as they ratchet over and come to rest in a locked position against said rocks of teeth.

Total Claims: 11
Claim 1
Independent Claim
231 words
A cable tie comprising a unitary strap and head, said strap having a spaced parallel pair of racks of teeth extending along the length thereof, each of said teeth having a root and a crest with the crest of one tooth integrally joining the root of the next tooth with no break between them, said teeth in one of said racks being juxtaposed in an aligned relationship with the teeth in the other of said racks whereby crests of said teeth in each of said racks are in contiguous alignment, a pair of cantilevered positioned side-by-side with in said head to confront, to pivot, and to prop at a free end against individually associated ones of said racks of teeth, said racks being separated by a medium strip having a substantially full strap thickness which at least equals the thickness of the strap at the crests of the teeth for adding plastic to said strap in the area where said free end of said cantilevered pawls prop against said teeth in said strap, said pawls being separated from each other by a distance approximately equal to the width of said median strip so that each pawl is guided and directed by said median strap as it ratchets over its individually associated one of said rack of teeth to come to rest in a propping position against confronting teeth on said strap.
Claim 2
Dependent Claim
231 words
A cable tie comprising a unitary strap and head, said strap having a spaced parallel pair of racks of teeth extending along the length thereof, each of said teeth having a root and a crest with the crest of one tooth integrally joining the root of the next tooth with no break between them, said teeth in one of said racks being juxtaposed in an aligned relationship with the teeth in the other of said racks whereby crests of said teeth in each of said racks are in contiguous alignment, a pair of cantilevered positioned side-by-side with in said head to confront, to pivot, and to prop at a free end against individually associated ones of said racks of teeth, said racks being separated by a medium strip having a substantially full strap thickness which at least equals the thickness of the strap at the crests of the teeth for adding plastic to said strap in the area where said free end of said cantilevered pawls prop against said teeth in said strap, said pawls being separated from each other by a distance approximately equal to the width of said median strip so that each pawl is guided and directed by said median strap as it ratchets over its individually associated one of said rack of teeth to come to rest in a propping position against confronting teeth on said strap.
Claim 3
Dependent Claim
39 words
The cable tie of claim 1 wherein each of said teeth has a predetermined contour, and each of said pawls has a plurality of teeth with contours which are complementary to the contours of said teeth in said rack.
Claim 4
Dependent Claim
41 words
The cable tie of claim 2 wherein the teeth on one of said pawls is juxtaposed in parallel relationship with the teeth on the other of said pawls whereby the crests of the teeth of said pawls are in side-by-side alignment.
Claim 5
Dependent Claim
195 words
An integral, plastic fastener comprising a continuous and unbroken strap having a securing means at one end, the opposite end of said strap being free, said strap having two spaced parallel rows of teeth extending along the length of said strap, each of said teeth in said rows rising from a root of a discrete strap thickness to a crest of greater strap thickness, said teeth in one of said rows being juxtaposed in an aligned relationship with the teeth in the other of said rows whereby the crests of said teeth in each of said racks are in contiguous alignment, said two rows of teeth being separated by a median strip having a thickness that is substantially as great as at least the thickness of said strap at a crest of said teeth, and a cantilevered hinged pawl associated with each of said rows of teeth, each pawl having teeth which are complementary to and which ratchet over and latch by propping against said teeth in the row associated therewith, said pawls being guided and directed by said median strip as they ratchet over said teeth and come to rest in a locking position.
Claim 6
Dependent Claim
195 words
An integral, plastic fastener comprising a continuous and unbroken strap having a securing means at one end, the opposite end of said strap being free, said strap having two spaced parallel rows of teeth extending along the length of said strap, each of said teeth in said rows rising from a root of a discrete strap thickness to a crest of greater strap thickness, said teeth in one of said rows being juxtaposed in an aligned relationship with the teeth in the other of said rows whereby the crests of said teeth in each of said racks are in contiguous alignment, said two rows of teeth being separated by a median strip having a thickness that is substantially as great as at least the thickness of said strap at a crest of said teeth, and a cantilevered hinged pawl associated with each of said rows of teeth, each pawl having teeth which are complementary to and which ratchet over and latch by propping against said teeth in the row associated therewith, said pawls being guided and directed by said median strip as they ratchet over said teeth and come to rest in a locking position.
Claim 7
Dependent Claim
72 words
The fastener of claim 4 wherein each pawl has a plurality of teeth, the teeth on one of said pawls being juxtaposed in an aligned relationship with the teeth on the other of said pawls whereby the crests of the teeth of each of said pawls are in contiguous alignment, the teeth of each of said pawls simultaneously propping themselves against the teeth in each of said two rows of said teeth.
Claim 8
Dependent Claim
217 words
An integral, elongated plastic device having a continuous and unbroken strap on one end and a fastener on the other end, a plurality of rows of spaced parallel teeth extending along the length of the strap, each of said teeth rising from a root to a crest with at least a minimum amount of plastic strap thickness at said rotor and a maximum amount of plastic strap thickness at said crest, the average strap thickness at any transverse location along the length of said strap being greater than said minimum amount, said teeth in each of said rows being juxtaposed in an aligned relationship whereby the crests of said teeth in each of said rows are in substantially contiguous alignment, two side walls extending along opposite edges of said strap, a median strip extending along the length of said strap between adjacent rows of said teeth, said side walls and said median strip having a plastic strap thickness at least as great as said maximum amount of plastic strap thickness, a hinged pawl securing means on said fastener and individually associated with each of said rows for ratcheting over said teeth in said rows, said hinged pawl securing means propping against and locking into at least one of said teeth to preclude a loosening of said strap.
