Abstract

An adapter for a QD socket is disclosed. The adapter has a connection post having a plurality of tabs movable relative to each other between a first configuration and a second configuration. The first configuration defines a maximum effective outer diameter of the connection post, and the second configuration defines a minimum effective outer diameter of the connection post. A method of modifying a quick disconnect attachment is also disclosed.

First claim

What is claimed is:

1. An adapter for a QD socket, comprising:
a first post portion having a proximal region, a distal region, a longitudinal axis extending between the proximal region and the distal region, a loop, and a first tab shaped to interface with a QD socket;
a second post portion having a longitudinal axis coincident with the longitudinal axis of the first post portion, a second tab shaped to interface with the QD socket; and
a guide mechanism shaped to limit rotation of the second post portion relative to the first post portion, the guide mechanism having a guide ridge in one of the first post portion or the second post portion interfacing with a guide valley in the other one of the first post portion or the second post portion; wherein
the second post portion is coupled to the first post portion and translatable along the longitudinal axis of the first post portion between a first configuration defining a first transverse distance between the first and second tabs and a second configuration defining a second transverse distance between the first and second tabs, the first transverse distance greater than the second transverse distance; and wherein
the second post portion is positioned closer to the proximal region of the first post portion in the first configuration than in the second configuration.

2. The adapter of claim 1 , wherein:
the guide ridge is in the second post portion and the guide valley is in the first post portion.

3. The adapter of claim 2 , wherein:
the guide mechanism further comprises a travel stop shaped to limit the second post portion to travel between the first configuration and the second configuration.

4. The adapter of claim 3 , wherein:
the travel stop comprises a first seat in the first post portion, the first seat comprising a first contact surface perpendicular to the longitudinal axis of the first post portion; and
the travel stop comprises a second seat in the first post portion, the second seat comprising a second contact surface parallel to the longitudinal axis; and further wherein
the first seat defines the first configuration and the second seat defines the second configuration.

5. The adapter of claim 1 , wherein:
the second post portion abuts the first post portion at an angle relative to the longitudinal axis of the first post portion, the angle between 15 degrees and 45 degrees; and
a fastener couples the first and second post portions, wherein adjustment of the fastener causes the first and second post portions to slide relative to each other.

6. The adapter of claim 1 , further comprising:
a through passage in the first post portion, the through passage shaped to allow a fastener to pass therethrough and to allow the fastener to translate transversely relative to the longitudinal axis; and
a fastener engagement in the second post portion, the fastener engagement shaped to allow the second post portion to translate longitudinally relative to the fastener.

7. The adapter of claim 1 , wherein:
the second post portion is shaped to pass into a minimum diameter of a QD socket when the adapter is in the second configuration.

8. The adapter of claim 1 , wherein
the first and second tabs are shaped to interface with one of a continuous annular groove in a QD socket, a discontinuous annular groove in a QD socket, and a plurality of openings in a QD socket.

9. A method of modifying a quick disconnect interface into a semi-permanent attachment point, comprising:
providing an adapter assembly having a plurality of tabs, the plurality of tabs movable between a first configuration having a first transverse distance between the plurality of tabs and a second configuration having a second transverse distance between the plurality of tabs, the first transverse distance greater than the second transverse distance;
adjusting the adapter assembly to the second configuration;
inserting a distal portion of the adapter into a quick disconnect (QD) socket;
orienting an accessory attachment interface on the adapter assembly to a desired position;
adjusting the adapter assembly to the first configuration wherein the first and second tabs engage an interior recess in the QD socket to selectively couple the adapter assembly to the QD socket;
causing a first seat in the first post portion to contact a first contact surface in the first configuration; and
causing a second seat in the first post portion to contact a second contact surface in the second configuration.

10. The method of claim 9 , further comprising:
limiting rotation of a second post portion of the adapter assembly relative to a first post portion of the adapter assembly.

11. The method of claim 10 , further comprising:
limiting the second post portion to travel between the first configuration and the second configuration.

12. The method of claim 10 , wherein:
the first contact surface is a perpendicular contact surface; and
the second contact surface is a parallel contact surface.

13. The method of claim 9 , further comprising:
adjusting a fastener to cause the adapter assembly to move between the first configuration and the second configuration.

14. The method of claim 9 , further comprising:
causing the plurality of tabs to interface with one of a continuous annular groove in a QD socket, a discontinuous annular groove in a QD socket, and a plurality of openings in a QD socket.

15. The method of claim 9 , wherein:
the accessory attachment interface is a loop.

16. The method of claim 9 , wherein:
adjusting to the first configuration comprises causing transverse movement of a first portion of the adapter assembly relative to a second portion of the adapter assembly, thereby narrowing an effective outer diameter of the distal portion of the adapter assembly; and
adjusting to the second configuration comprises causing transverse movement of the first portion relative to the second portion, thereby widening an effective outer diameter of the distal portion of the adapter assembly.

17. An adapter for a quick disconnect (QD) socket, comprising:
a connection post having a first tab and a second tab movable relative to each other between a first configuration and a second configuration, the first configuration defining a maximum effective outer diameter of the connection post, and the second configuration defining a minimum effective outer diameter of the connection post;
a travel stop configured to limit the connection post to movement between the first configuration and the second configuration; and
a threaded fastener coupling the first tab and the second tab; wherein
the first tab and the second tab are in a plane perpendicular to a longitudinal axis of the connection post in the first configuration and not in the second configuration.

18. The adapter of claim 17 , further comprising:
a guide mechanism shaped to limit rotation of the first and second tabs relative to one another.

19. The adapter of claim 17 , wherein:
the travel stop comprises a first contact surface perpendicular to a longitudinal axis of the connection post and a second contact surface parallel to the longitudinal axis; and further wherein
the first contact surface defines the first configuration and the second contact surface defines the second configuration.

20. The adapter of claim 17 , wherein:
at least one of the first and second tabs is movable at an angle relative to another of the first and second tabs at an angle, the angle between 15 degrees and 45 degrees.

21.
