Latch systems and methods for straps

1. A latch system comprising:

a socket assembly comprising

a socket housing defining a primary chamber, a secondary chamber, and a main opening, and

a socket magnet member arranged within the secondary chamber; and

a plug assembly comprising

a head portion defining a head gap, and

a plug magnet member supported relative to the head portion; and

a cord attached to the socket assembly; whereby

when the socket assembly is within a predetermined distance from the plug assembly, the socket magnet member and plug magnet member displace the socket assembly towards the plug assembly;

to place the latch system in an engaged configuration, the head portion of the plug member passes through the main opening in the socket housing such that the head portion is within the primary chamber;

to place the latch system in a latched configuration, the socket assembly is displaced relative to the plug assembly to arrange at least a portion of the socket assembly within the head gap; and

to place the latch system in an unlatched configuration, applying tension on the cord when the latch system is in the latched configuration whereby the socket assembly is rotated relative to the plug assembly.

2. A latch system as recited in claim 1 , in which the head portion of the plug member defines an outer surface configured to guide the head portion of the plug member through the main opening in the socket housing.

3. A latch system as recited in claim 1 , in which the head portion of the plug member defines a frustoconical outer surface.

4. A latch system as recited in claim 1 , in which:

the head portion of the plug member defines a head cavity; and

the plug magnet member is arranged within the head cavity.

5. A latch system as recited in claim 1 , in which the housing defines at least one wall surface disposed at an angle to force the head portion of the plug member out of the primary chamber through the plug opening in the socket plate and the main opening in the socket housing when tension is applied on the cord.

6. A latch system as recited in claim 1 , the plug assembly further comprising a plug plate integrally formed with the plug member.

7. A latch system as recited in claim 1 , the plug assembly further comprising a plug plate rigidly attached to the plug member.

8. A latch system as recited in claim 1 , in which:

the socket assembly further comprises a socket plate defining a plug opening, where the socket plate is supported by the socket housing such that plug opening is at least partly aligned with the main opening; and

the plug assembly further comprises

a plug plate, and

a plug member comprising the head portion; wherein

the plug member is supported by the plug plate to define the head gap;

the plug magnet member is supported by the plug member;

to place the latch system in an engaged configuration, the head portion of the plug member passes through the plug opening in the socket plate such that the head portion is within the primary chamber; and

to place the latch system in a latched configuration, the socket assembly is displaced relative to the plug assembly to arrange at least a portion of the socket plate within the head gap.

9. A strap assembly comprising:

a latch system comprising

a socket assembly comprising

a socket housing defining a primary chamber, a secondary chamber, and a main opening,

a socket plate defining a plug opening, where the socket plate is supported by the socket housing such that plug opening is at least partly aligned with the main opening, and

a socket magnet member arranged within the secondary chamber; and

a plug assembly comprising

a plug plate,

a plug member comprising a head portion, where the plug member is supported by the plug plate to define a head gap, and

a plug magnet member supported relative to the plug member;

a strap operatively connected to the socket plate; and

an anchor assembly operatively connected to the plug plate; whereby

when the socket assembly is within a predetermined distance from the plug assembly, the socket magnet member and plug magnet member displace the socket assembly towards the plug assembly;

to place the latch system in an engaged configuration, the head portion of the plug member passes through the main opening in the socket housing and the plug opening in the socket plate such that the head portion is within the primary chamber;

to place the latch system in a latched configuration, the strap is tensioned such that the socket assembly is displaced relative to the plug assembly to arrange at least a portion of the socket plate within the head gap; and

a cord attached to the socket assembly, where applying tension on the cord when the latch system is in the latched configuration rotates the socket assembly relative to the plug assembly to place the latch system in an unlatched configuration.

10. A strap assembly as recited in claim 9 , in which the head portion of the plug member defines an outer surface configured to guide the head portion of the plug member through the main opening in the socket housing and the plug opening in the socket plate.

11. A strap assembly as recited in claim 9 , in which the head portion of the plug member defines a frustoconical outer surface.

12. A strap assembly as recited in claim 9 , in which:

the head portion of the plug member defines a head cavity; and

the plug magnet member is arranged within the head cavity.

13. A strap assembly as recited in claim 9 , in which the housing defines at least one wall surface disposed at an angle to force the head portion of the plug member out of the primary chamber through the plug opening in the socket plate and the main opening in the socket housing when tension is applied on the cord.

14. A strap assembly as recited in claim 9 , further comprising a shaping member to configure the reach of the strap.

15. A strap assembly as recited in claim 14 , further comprising a cover arranged to cover at least a portion of the strap and at least a portion of the shaping member.

16. A latch system comprising:

a socket assembly comprising a socket housing defining a primary chamber and a main opening, and

a plug assembly comprising a head portion defining a head gap; and

a cord operatively connected to one of the socket assembly and the plug assembly; whereby

to place the latch system in an engaged configuration, the head portion of the plug member passes through the main opening in the socket housing such that the head portion is within the primary chamber; and

to place the latch system in a latched configuration, the socket assembly is displaced relative to the plug assembly to arrange at least a portion of the socket assembly within the head gap; and

to place the latch in an unlatched configuration, the cord is placed under tension such that one of the socket assembly and the plug assembly is rotated relative to the other of the socket assembly and the plug assembly.

17. A latch system as recited in claim 16 , further comprising:

a socket magnet member arranged within a secondary chamber defined by the socket housing;

a plug magnet member supported relative to the plug assembly; wherein

when the socket assembly is within a predetermined distance from the plug assembly, the socket magnet member and plug magnet member displace the socket assembly towards the plug assembly.

18. A latch system as recited in claim 16 , in which the socket housing defines at least one wall surface arranged to force the head portion out of the primary chamber through the main opening when one of the socket assembly and the plug assembly is rotated relative to the other of the socket assembly and the plug assembly.
