Abstract
Abstract A one-piece synthetic plastic tie, for tying around a bundle of cables or the like and for securing the bundle to a panel, comprises a flexible elongate strap provided with a series of ratchet serrations (on its side lying against the bundle of cables) engaging with complementary teeth formed on a head at one end of the strap. In use, the free end of the strap is passed through a hole in the panel, around the cable bundle and back through the hole. When the free end of the strap is pulled tight, the head is pulled into the hole to wedge the strap against the periphery of the hole, the head teeth engaging the strap serrations to prevent withdrawal.

Claim 1
Independent Claim
240 words
Tie means for connecting a bundle of cables to one side of a panel containing an opening, comprising a flexible elongated strap member (12) formed of synthetic plastic material, said strap member including (a) a horizontal flat body portion one horizontal surface of which contains a plurality of longitudinally extending serrations (13); and (b) an enlarged head portion (14) connected with one end of said body portion, said head portion including means defining a pawl portion (22) having upper and lower surfaces arranged above and below the horizontal axis of said body portion, that one of said pawl surfaces which is on the same side of the central axis of said body portion as said one serrated horizontal surface containing a plurality of longitudinally arranged pawl teeth (24) adapted for cooperation with said serrations, the other one of said pawl surfaces being inclined and converging toward said body portion, whereby when the other end of said body portion is introduced from the opposite side of the panel through the panel opening, circumferentially around the cable bundle, and back through the panel opening to cause the pawl teeth to be opposite said serrations, further tensioning of said other end of said strap portion causes said pawl portion to be drawn within said opening thereby to wedge said body portion between an edge of the panel opening and the pawl portion and to lock the serrations into engagement with the pawl teeth.

Tie means for connecting a bundle of cables to one side of a panel containing an opening, comprising a flexible elongated strap member (12) formed of synthetic plastic material, said strap member including (a) a horizontal flat body portion one horizontal surface of which contains a plurality of longitudinally extending serrations (13); and (b) an enlarged head portion (14) connected with one end of said body portion, said head portion including means defining a pawl portion (22) having upper and lower surfaces arranged above and below the horizontal axis of said body portion, that one of said pawl surfaces which is on the same side of the central axis of said body portion as said one serrated horizontal surface containing a plurality of longitudinally arranged pawl teeth (24) adapted for cooperation with said serrations, the other one of said pawl surfaces being inclined and converging toward said body portion, whereby when the other end of said body portion is introduced from the opposite side of the panel through the panel opening, circumferentially around the cable bundle, and back through the panel opening to cause the pawl teeth to be opposite said serrations, further tensioning of said other end of said strap portion causes said pawl portion to be drawn within said opening thereby to wedge said body portion between an edge of the panel opening and the pawl portion and to lock the serrations into engagement with the pawl teeth.
Claim 3
Dependent Claim
21 words
Tie means as defined in claim 1, wherein said one toothed pawl surface is inclined and converges toward said body portion.
Claim 4
Dependent Claim
71 words
Tie means as defined in claim 1 or 2, wherein the other horizontal surface of said body portion contains a plurality of longitudinally extending serrations, and further wherein the other of said inclined pawl surfaces contains a plurality of longitudinally arranged pawl teeth adapted to cooperate with said serrations in the other horizontal body portion surface, whereby said body portion may be passed circumferentially around the cable bundle in either direction.
Claim 5
Dependent Claim
36 words
Tie means as defined in claim 3, wherein said head portion further includes (1) a frusto-conical portion (18) converging toward said body portion; and (2) a transverse slot (20) within which said pawl portion is arranged.
Claim 6
Dependent Claim
206 words
Tie means for connecting a bundle of cables to one side of a panel containing an opening, comprising a flexible elongated strap member (12) formed of synthetic plastic material, said strap member including (a) a horizontal flat body portion one horizontal surface of which contains a plurality of longitudinally extending serrations (13); and (b) an enlarged head portion (14) connected with one end of said body portion, said head portion including means defining a pawl portion (22), that surface of the pawl portion on the same side of the central axis of said body portion as said serrated horizontal surface containing a plurality of longitudinally arranged pawl teeth (24) adapted for cooperation with said serrations, whereby when the other end of said body portion is introduced from the opposite side of the panel through the panel opening, circumferentially around the cable bundle, and back through the panel opening to cause the pawl teeth to be opposite said serrations, further tensioning of said other end of said strap portion causes said pawl portion to be drawn within said opening thereby to wedge said body portion between an edge of the panel opening and the pawl portion and to lock the serrations into engagement with the pawl teeth.
Claim 7
Dependent Claim
206 words
Tie means for connecting a bundle of cables to one side of a panel containing an opening, comprising a flexible elongated strap member (12) formed of synthetic plastic material, said strap member including (a) a horizontal flat body portion one horizontal surface of which contains a plurality of longitudinally extending serrations (13); and (b) an enlarged head portion (14) connected with one end of said body portion, said head portion including means defining a pawl portion (22), that surface of the pawl portion on the same side of the central axis of said body portion as said serrated horizontal surface containing a plurality of longitudinally arranged pawl teeth (24) adapted for cooperation with said serrations, whereby when the other end of said body portion is introduced from the opposite side of the panel through the panel opening, circumferentially around the cable bundle, and back through the panel opening to cause the pawl teeth to be opposite said serrations, further tensioning of said other end of said strap portion causes said pawl portion to be drawn within said opening thereby to wedge said body portion between an edge of the panel opening and the pawl portion and to lock the serrations into engagement with the pawl teeth.
Claim 8
Dependent Claim
28 words
Tie means as defined in claim 5, wherein said toothed pawl surface is spaced from the central axis of, and converges in the direction of, said body portion.
Claim 9
Dependent Claim
38 words
Tie means as defined in claim 5 or 6, wherein said head portion further includes (1) a frusto-conical portion (18) converging toward said body portion; and (2) a transverse slot (20) within which said pawl portion is arranged.
Claim 10
Dependent Claim
197 words
Cable bundle tie means, comprising (a) means defining an opening; and (b) a flexible elongated strap member (12) formed of synthetic plastic material, said strap member including (1) a horizontal flat body portion the opposite horizontal surfaces of which each contain a plurality of longitudinally extending serrations (13); and (2) an enlarged head portion (14) connected with one end of said body portion, said head portion including means defining a pawl portion (22) having upper and lower pawl surfaces arranged above and and below the horizontal axis of said body portion, said pawl surfaces being relatively inclined at an acute angle and converging toward said body portion, both of said pawl surfaces containing a plurality of longitudinally arranged pawl teeth (24) adapted for cooperation with said serrations, whereby when the other end of said body portion is introduced from one side of the opening, circumferentially around the cable bundle, and back through the opening to cause the pawl teeth to be opposite said serrations, tensioning of said other end of said strap portion causes said pawl portion to be drawn within said opening to wedge the serrations of said body portion into engagement with the pawl teeth.
