Abstract

This document describes an integrated release feature for pawl-latching devices. In particular, the integrated release feature is integrally connected to a pawl that is connected to a locking head of the pawl-latching device. The locking head defines a slot that extends through the locking head and includes a first channel conjoined with a second channel. The pawl is disposed within the second channel and positioned internally to the locking head. The pawl has multiple pawl teeth to engage serrations on an elongate strap when the elongate strap is disposed within the first channel. The integrated release feature includes at least one wall shaped to define multiple sides of an open cavity in a midsection of the pawl for receiving a release tool, and the wall has opposing ends that both face the first channel and have one or more additional pawl teeth.

First claim

What is claimed:

1. A pawl-latching device comprising:
an integrated release feature integrally connected to a pawl that is connected to a locking head of the pawl-latching device, the locking head defining a slot that extends through the locking head and includes a first channel conjoined with a second channel, the first channel configured to receive an elongate strap having a plurality of serrations, the pawl disposed within the second channel of the slot and positioned internally to the locking head, the pawl having multiple pawl teeth configured to engage the plurality of serrations on the elongate strap when the elongate strap is disposed within the first channel, the integrated release feature comprising:
at least one wall shaped to define multiple sides of an open cavity in a midsection of the pawl for receiving a release tool, the at least one wall having opposing ends that both face the first channel; and
one or more additional pawl teeth disposed on the opposing ends of the at least one wall that face the first channel.

2. The pawl-latching device as recited in claim 1 , wherein the pawl includes a planar surface defining a bottom of the cavity, the planar surface having an indentation configured to receive a tip of the release tool to prevent slidable movement of the tip of the release tool toward the first channel across the planar surface of the pawl.

3. The pawl-latching device as recited in claim 1 , wherein:
the at least one wall includes a back wall merged with two side walls to form a U-shaped structure around the cavity; and
the one or more pawl teeth are disposed on an end of each side wall that faces the first channel.

4. The pawl-latching device as recited in claim 3 , wherein the back wall is configured to reinforce the side walls to provide increased wedging strength for the one or more additional pawl teeth.

5. The pawl-latching device as recited in claim 3 , wherein integration of the side walls with the back wall provides reinforcement strength to the back wall for releasing the one or more pawl teeth when the one or more pawl teeth are compressively engaged with one or more serrations of the plurality of serrations on the elongate strap and a force is applied to the back wall in a direction away from the elongate strap.

6. The pawl-latching device as recited in claim 1 , wherein the cavity is formed by a bifurcation in a portion of the pawl including a portion of the one or more pawl teeth that face the first channel.

7. The pawl-latching device as recited in claim 1 , wherein the at least one wall is shaped to define the cavity to size-match to an industry-standard flat-blade screwdriver.

8. The pawl-latching device as recited in claim 1 , wherein the at least one wall is shaped to fit a contour of a tip of the release tool.

9. The pawl-latching device as recited in claim 1 , wherein the one or more additional pawl teeth are arranged in two substantially parallel columns separated by the cavity.

10. The pawl-latching device as recited in claim 1 , wherein the integrated release feature is positioned internally to the locking head such that the integrated release feature does not extend outside of the locking head.

11. The pawl-latching device as recited in claim 1 , wherein a surface of the integrated release feature is substantially flush with an outer surface of the locking head.

12. A pawl-latching device comprising:
an elongate strap having a head end, a tail end that is opposite the head end, and a plurality of serrations disposed on one side of the elongate strap;
a locking head integrally connected to the head end of the elongate strap, the locking head defining a slot that extends through the locking head and includes first and second conjoined channels, the first channel configured for receiving the strap with the plurality of serrations;
a pawl disposed within the second channel via a hinged connection to the locking head and positioned below a top surface of the locking head, the pawl including a plurality of pawl teeth disposed on a face of the pawl that faces the first channel, the plurality of pawl teeth configured to engage one or more serrations of the plurality of serrations when the tail end of the elongate strap is disposed within the first channel; and
an integrated release feature integrally connected to the pawl, the integrated release feature comprising a multi-walled structure defining multiple sides of the cavity and having ends facing the first channel, the multi-walled structure defining a cavity in a midsection of the pawl that is configured to receive a release tool, the ends of the multi-walled structure having one or more additional pawl teeth.

13. The pawl-latching device as recited in claim 12 , wherein the pawl includes an indentation in a planar surface of the pawl that defines a bottom of the cavity, the indentation configured to receive a tip of the release tool to prevent lateral movement of the tip of the release tool toward or away from the first channel.

14. The pawl-latching device as recited in claim 12 , wherein the multi-walled structure is formed to define the cavity to fit a contour and size of a tip of the release tool.

15. The pawl-latching device as recited in claim 14 , wherein the release tool comprises a flat-blade tip.

16. The pawl-latching device as recited in claim 14 , wherein the multi-walled structure has a height within a range of approximately 1.0 mm to approximately 3.0 mm.

17. The pawl-latching device as recited in claim 12 , wherein the multi-walled structure includes a back wall integrally connected to two side walls to form a U-shaped structure around the cavity.

18. The pawl-latching device as recited in claim 17 , wherein the side walls are separated by a distance that is within a range of approximately 0.8 mm to approximately 10 mm.

19. The pawl-latching device as recited in claim 17 , wherein the back wall is offset from the face of the pawl by a distance that is within a range of approximately 0.5 mm to approximately 2 mm.

20. The pawl-latching device as recited in claim 12 , wherein the multi-walled structure includes a back wall and two side walls that together define the cavity, the back wall being disjointed from the two side walls, the two side walls configured to guide a tip of the release tool, the two side walls having one or more rows of pawl teeth facing the first channel and configured to engage one or more serrations of the plurality of serrations of the elongate strap when the elongate strap is disposed within the first channel.
