Cable strap with multiple tooth pawl

Claim 2

A cable strap of unitary construction comprising an elongated body of generally rectangular cross section with an enlarged head connected to one end of said strap, there being a passage through said head adapted to receive the looped remote end of the strap to form a loop for holding objects therein, the invention wherein within said head passage there is an elongated, flexible pawl integrally and curvedly connected to said strap and extending freely into said passage between the sidewalls, the body of said pawl comprising an extension of the strap narrowing in thickness from the thickness of the strap at its pivotal connection thereto, an alignment of ratchet teeth incised into one face of the strap adjacent the remote end of said strap and a first tooth and second tooth on said pawl protruding normally into the passage confronting the end wall of the head and spaced in the path of the looped end of said strap the first of said teeth positioned to cause flexure of said pawl body as the tooth matingly engages said ratchet teeth as the remote end of the strap body is threaded through the passage in said head, the second of said teeth positioned to be moved away from strap remote end during said threading and to restore and hold the strap remote end against the end wall of said head when fully looped through the head.

Claim 3

A cable strap as claimed in claim 1, wherein the teeth on the pawl have their tips blunted to mate with like spacings between the ratchet teeth in the strap face.

Claim 4

A strap as claimed in claim 1, wherein said pawl has side walls which taper toward convergence adjacent the first of said two teeth.

Claim 5

A strap as claimed in claim 1, wherein there is a third tooth on said pawl positioned intermediate between said first and second tooth.

Claim 6

A cable strap of unitary construction comprising an elongated body of generally rectangular cross section having ratched teeth with an enlarged head connected to one end of said strap, there being a passage through said head adapted to receive the looped end of the strap to form a loop for holding objects therein, the invention wherein within said head passage there is an elongated, flexible pawl integrally and curvedly connected to said strap and extending freely into said sidewalls, the body of said pawl comprising a smoothly curved concave-convex member of generally decreasing cross section and at least a lower and upper tooth protruding from said pawl body adjacent the free end thereof, said teeth spaced along said passage and spaced from and confronting the end wall of the head, said pawl tapering from its connection to the strap to a narrowed section adjacent the lower of said teeth, said pawl adapted to be flexed by said strap end to remove the upper tooth from contact with said strap end during movement of said strap through said head passage and said lower tooth protrusive from said narrowed section to matingly engage said ratchet teeth as the remote end of the strap body is threaded through the passage, said upper tooth aligned to restore from said flexed position at the termination of movement of said strap through said passage, said upper tooth aligned opposite said end wall to restrain said strap against said end wall to prevent withdrawal of said strap from said passage.

Claim 7

A cable strap of unitary construction comprising an elongated body of generally rectangular cross section having ratched teeth with an enlarged head connected to one end of said strap, there being a passage through said head adapted to receive the looped end of the strap to form a loop for holding objects therein, the invention wherein within said head passage there is an elongated, flexible pawl integrally and curvedly connected to said strap and extending freely into said sidewalls, the body of said pawl comprising a smoothly curved concave-convex member of generally decreasing cross section and at least a lower and upper tooth protruding from said pawl body adjacent the free end thereof, said teeth spaced along said passage and spaced from and confronting the end wall of the head, said pawl tapering from its connection to the strap to a narrowed section adjacent the lower of said teeth, said pawl adapted to be flexed by said strap end to remove the upper tooth from contact with said strap end during movement of said strap through said head passage and said lower tooth protrusive from said narrowed section to matingly engage said ratchet teeth as the remote end of the strap body is threaded through the passage, said upper tooth aligned to restore from said flexed position at the termination of movement of said strap through said passage, said upper tooth aligned opposite said end wall to restrain said strap against said end wall to prevent withdrawal of said strap from said passage.
