Abstract
Abstract A moulded one-piece tie of plastics material for typing around a bundle of cables and the like comprising a flexible strap having serrations on one surface for locking with transverse teeth formed on a pivoted pawl when a free end of the strap is passed through an apertured head which is at the other end of the strap and which contains the pawl. Tension in the strap tending to withdraw it from the aperture pivots the pawl to more firmly grip the strap against an abutment surface opposite the pawl and to bend the strap over a transverse, substantially 90* ridge formed on the abutment surface intermediate the pawl pivot and the opposite end of the pawl.

Claim 1
Independent Claim
365 words
A one piece molded tie of plastics material comprising: a. a flexible elongate strap; b. a head at one end of said strap; c. there being an aperture extending through said head in a direction transverse to the plane of said strap; d. a pivotally mounted pawl disposed within said aperture; e. at least one first transverse tooth formed on said pawl; f. at least one second transverse tooth formed on said pawl; g. all said first and second teeth having their crests in a common flat plane; h. a wall on said head defining an abutment surface on one side of said aperture opposite said pawl and parallel to said common plane of pawl teeth crests while the top of said wall defines a surface substantially perpendicular to said abutment surface; i. a transverse ridge formed by a junction between said abutment surface and said substantially perpendicular surface; j. the projection of the crest of said at least one first pawl tooth onto the plane of said abutment surface lying, over at least substantially the whole pivotal movement of said pawl, further than said ridge from the projection of the pivot of the pawl onto said abutment surface; k. the projection of the crest of said at least one second pawl tooth onto the plane of said abutment surface lying closer than said ridge to the projection of the pivot of the pawl onto said abutment surface; l. said pawl, in the manufactured condition of the tie, being spaced from the plane of said abutment surface; m. a series of transverse ratchet serrations formed on one side of said strap; and n. said ratchet serrations and pawl teeth being complementarily profiled to cooperate and permit passage of the free end of the strap through said aperture from the pivoted end of said pawl but to prevent subsequent withdrawal of said strap in the opposite direction; and tension applied to said strap in said opposite direction serving to pivot said pawl for said at least one second pawl tooth to firmly grip said strap flat against said abutment surface and said at least one first pawl tooth to bend said strap over said transverse ridge.

A one piece molded tie of plastics material comprising: a. a flexible elongate strap; b. a head at one end of said strap; c. there being an aperture extending through said head in a direction transverse to the plane of said strap; d. a pivotally mounted pawl disposed within said aperture; e. at least one first transverse tooth formed on said pawl; f. at least one second transverse tooth formed on said pawl; g. all said first and second teeth having their crests in a common flat plane; h. a wall on said head defining an abutment surface on one side of said aperture opposite said pawl and parallel to said common plane of pawl teeth crests while the top of said wall defines a surface substantially perpendicular to said abutment surface; i. a transverse ridge formed by a junction between said abutment surface and said substantially perpendicular surface; j. the projection of the crest of said at least one first pawl tooth onto the plane of said abutment surface lying, over at least substantially the whole pivotal movement of said pawl, further than said ridge from the projection of the pivot of the pawl onto said abutment surface; k. the projection of the crest of said at least one second pawl tooth onto the plane of said abutment surface lying closer than said ridge to the projection of the pivot of the pawl onto said abutment surface; l. said pawl, in the manufactured condition of the tie, being spaced from the plane of said abutment surface; m. a series of transverse ratchet serrations formed on one side of said strap; and n. said ratchet serrations and pawl teeth being complementarily profiled to cooperate and permit passage of the free end of the strap through said aperture from the pivoted end of said pawl but to prevent subsequent withdrawal of said strap in the opposite direction; and tension applied to said strap in said opposite direction serving to pivot said pawl for said at least one second pawl tooth to firmly grip said strap flat against said abutment surface and said at least one first pawl tooth to bend said strap over said transverse ridge.
Claim 3
Dependent Claim
109 words
A tie as claimed in claim 1, comprising: a second surface of said step; a further surface substantially perpendicular to said abutment surface; a further transverse tooth on said pawl with its crest lying in said common plane; a second transverse ridge formed by a junction between said second surface of said step and said further substantially perpendicular surface, said second ridge being disposed so that the projection thereof on to the plane of said abutment surface lies, for at least substantially the whole pivotal movement of said pawl, between the projections onto that plane of the crest of said further pawl tooth and the pivot of said pawl.
