Abstract

A cable tie includes a cable tie head; and a strap. The head is configured to receive the strap. A least part of the head comprises a deformable zone configured to deform when the strap is received in the cable tie head to secure the cable tie to an elongate article.

First claim

We claim:

1. A cable tie, comprising:
a cable tie head; and
a strap, wherein the cable tie head is configured to receive the strap, wherein at least part of the cable tie head comprises a deformable zone configured to deform when the strap is received in the cable tie head to secure the cable tie to an elongate article,
wherein the strap defines a plurality of serrations,
wherein the cable tie head further comprises a first wall arranged opposite a second wall that define an aperture extending through the cable tie head, the aperture having a first opening through which the strap enters the aperture and a second opening through which the strap exits the aperture,
wherein the first wall comprises a pawl with a plurality of teeth configured to engage the plurality of serrations of the strap,
wherein the second wall comprises the deformable zone, wherein the deformable zone extends from a first portion with a first thickness that is proximate to the first opening to a second portion having a second thickness that is proximate the second opening, wherein the second thickness is greater than the first thickness.

2. The cable tie in accordance with claim 1 , wherein the deformable zone is configured to deform in response to application of a force on the strap when securing the cable tie to the elongate article.

3. The cable tie in accordance with claim 2 , wherein the second wall defines a slot that is less than a width of the second wall and wherein the slot extends through the deformable zone.

4. The cable tie in accordance with claim 1 , wherein the second wall defines a converging angle between the first thickness and the second thickness that is greater than 1 degree.

5. The cable tie in accordance with claim 4 , wherein the converging angle between the first thickness and the second thickness is in a range of 1 to 10 degrees inclusive.

6. The cable tie in accordance with claim 2 , wherein the second wall defines a slot that is less than a width of the second wall, wherein the slot extends through the second wall opposite the pawl, and wherein the second wall is shorter than the first wall.

7. The cable tie in accordance with claim 1 , wherein at least a section the deformable zone varies gradually between the first thickness and the second thickness.

8. The cable tie in accordance with claim 1 , wherein at least a section of the deformable zone varies continuously between the first thickness and the second thickness.

9. The cable tie in accordance with claim 1 , wherein the first portion of the deformable zone is configured to flare outwardly at the first opening away from the first wall after the strap is inserted within the aperture and tightened around the elongate article.

10. The cable tie in accordance with claim 1 , wherein the aperture defines a third wall that is generally perpendicular to the second wall and wherein the third wall has a third thickness that is greater than a sum of the first thickness and the second thickness.

11. The cable tie in accordance with claim 1 , wherein a ratio of the first thickness to the second thickness in a range of 1:3 to 1:10.

12. The cable tie in accordance with claim 1 , wherein the strap extends from the cable tie head in a direction generally perpendicular to a longitudinal axis of the aperture extending from the first opening to the second opening.

13. The cable tie in accordance with claim 1 , wherein a ratio of a width of the second wall to a height of the second wall is in a range of 1:3 to 3:4.

14. The cable tie in accordance with claim 1 , wherein the deformable zone is flexible and configured to deform outwardly away from the first wall after the strap is inserted within the aperture and tightened around the elongate article.

15. The cable tie in accordance with claim 14 , wherein the second wall and the strap are in continuous contact with 330 to 355 degrees of a circumference of the elongate article after the strap is inserted within the aperture and tightened around the elongate article.

16. The cable tie in accordance with claim 14 , wherein a loop diameter defined by the second wall and the strap is substantially equal to a diameter of the elongate article after the strap is inserted within the aperture and tightened around the elongate article.

17. A cable tie, comprising:
a cable tie head;
an aperture extending through the cable tie head;
a strap defining a plurality of serrations extending from the cable tie head and configured to be received within the aperture, wherein the aperture defines a first opening through which the strap enters the aperture and a second opening through which the strap exits the aperture;
a first wall forming the aperture, wherein the first wall defines a pawl with a plurality of teeth configured to engage the plurality of serrations of the strap; and
a second wall forming the aperture opposite the first wall, wherein the second wall is shorter than the first wall and wherein the second wall does not extend past a first engaging tooth of the plurality of teeth of the pawl, the second wall further comprising a deformable zone configured to deform when the strap is received in the cable tie head to secure the cable tie to an elongate article, wherein the deformable zone extends from a first portion with a first thickness that is proximate to the first opening to a second portion having a second thickness that is proximate the second opening, and wherein the second thickness is greater than the first thickness.

18. The cable tie in accordance with claim 17 , wherein the strap extends from the cable tie head in a direction generally perpendicular to a longitudinal axis of the aperture extending from the first opening to the second opening.

19. The cable tie in accordance with claim 17 , wherein the second wall and the strap are in continuous contact with 260 to 300 degrees of a circumference of the elongate article after the strap is inserted within the aperture and tightened around the elongate article.

20. A cable tie, comprising:
a cable tie head;
an aperture extending through the cable tie head;
a strap defining a plurality of serrations extending from the cable tie head and configured to be received within the aperture, wherein the aperture defines a first opening through which the strap enters the aperture and a second opening through which the strap exits the aperture;
a first wall forming the aperture, wherein the first wall defines a pawl with a plurality of teeth configured to engage the plurality of serrations of the strap;
a second wall forming the aperture opposite the first wall; and
means for deforming the second wall in response to application of a force on the strap when securing the cable tie to an elongate article, wherein the means for deforming the second wall in response to application of a force on the strap when securing the cable tie to an elongate article extends from a first portion with a first thickness that is proximate to the first opening to a second portion having a second thickness that is proximate the second opening, wherein the second thickness is greater than the first thickness.
