Abstract

A latching system is described. The latching system includes a lower latch, an upper latch slidably engaging a top surface of the lower latch, a latch release mechanism connected to the upper latch, and a lock receiving member. The lower latch has a body with the top surface, a head formed at one end of the body, and a pivot formed at an opposite end of the body. The head includes a leading edge and a latching portion. The upper latch has a wedge portion. The receiving lock member has a lower arm with an upturned lip at a leading end formed to engage the leading edge of the lower latch, an inside face continuously formed with the leading end and a bottom formed on an inner part of the upturned lip, and an upper arm that engages the wedge portion of the upper latch.

Claims

1. A latching system, comprising:

a lower latch, the lower latch having,

a body with a top surface,

a head formed at one end of the body, the head including a leading edge and a latching portion, and

a pivot formed at an opposite end of the body;

an upper latch slidably engaging the top surface of the lower latch, the upper latch having a wedge portion;

a latch release mechanism coupled to the upper latch; and

a receiving lock member having,

a lower arm with an upturned lip at a leading end formed to engage the leading edge of the lower latch,

an inside face continuously formed with the leading end and a bottom formed on an inner part of the upturned lip, and,

an upper arm that engages the wedge portion of the upper latch.

2. A latching system according to claim 1, wherein the body has opposite side surfaces and the pivot is formed on one of the opposite side surfaces.

3. A latching system according to claim 1, wherein, the lower latch pivots when the lower latch engages the leading ends of the lower arm.

4. A latching system according to claim 1, wherein the upper latch prevents the pivoting of the lower latch when the upper latch engages the upper arm.

5. A latching system according to claim 1, further comprising a handle portion coupled to the latch release mechanism.

6. A latching system according to claim 1, wherein the lower latch and the upper latch lock into the receiving lock member.

7. A latching system according to claim 1, wherein the latch release mechanism includes a hole.

8. A latching system according to claim 1, wherein the latch release mechanism further comprises a spring supporting portion.

9. A latching system according to claim 8, further comprising:

a housing disposed substantially around the lower latch, the upper latch, and a portion of the latch release mechanism, the housing having,

a pivot support disposed on an inner surface of the housing to receive the pivot of the lower latch, and

a stop member disposed on the inner surface of the housing; and

a spring disposed between the spring supporting portion and the stop member.

10. A latching system according to claim 9, wherein the spring elastically biases the latch release member towards the receiving lock member and pulling the latch release mechanism disengages the upper latch from the upper arm to allow the lower latch to pivot.

11. A latching system according to claim 9, wherein the housing further comprises:

a side wall; and

a divider panel set apart from the side wall to form a side channel therebetween,

wherein the pivot support is disposed within the side channel to receive the pivot of the lower latch, the stop member is disposed at a distal end of the side channel, and the spring is disposed between the spring supporting portion and the stop member.

12. A latching system according to claim 9, wherein the housing is formed from a plurality of parts coupled to each other by a spring clip.

13. A latching system according to claim 9, further comprising a wafer disposed in the housing.

14. A latching system, comprising:

a plurality of lower latches, each of the plurality of lower latches having,

a body with a top surface,

a head formed at one end of the body, the head including a leading edge and a latching portion, and

a pivot formed at an opposite end of the body;

a plurality of upper latches, each of the plurality of upper latches slidably engaging the respective top surface of one of the plurality of lower latches, each of the plurality of upper latches having a wedge portion;

a latch release mechanism coupled to the plurality of upper latches; and

a plurality of receiving lock members, each of the plurality of receiving lock members having,

a lower arm with an upturned lip at a leading end formed to engage the leading edge of one of the plurality of lower latches,

an inside face continuously formed with the leading end and a bottom formed on an inner part of the upturned lip, and

an upper arm that engages the wedge portion of one of the plurality of upper latches.

15. A latching system according to claim 14, wherein the body has opposite side surfaces and the pivot is formed on one of the opposite side surfaces.

16. A latching system according to claim 14, wherein at least one of the plurality of lower latches pivot when the plurality of lower latches engages at least one of the corresponding leading ends of the lower arms.

17. A latching system according to claim 14, wherein the plurality of upper latches prevent the pivoting of the plurality of lower latches when at least one of the plurality of upper latches engages the upper arm.

18. A latching system according to claim 14, further comprising a handle portion coupled to the latch release mechanism.

19. A latching system according to claim 14, wherein the plurality of lower latches and the plurality of upper latches lock into the plurality of receiving lock members.

20. A latching system according to claim 14, wherein the latch release mechanism includes a hole.

21. A latching system according to claim 14, wherein the latch release mechanism further comprises a spring supporting portion.

22. A latching system according to claim 21, further comprising:

a housing disposed substantially around the plurality of lower latches, the plurality of upper latches, and a portion of the latch release mechanism, the housing having,

a plurality of pivot supports disposed on an inner surface of the housing to receive the pivots of the plurality of lower latches, and

a stop member disposed on the inner surface of the housing; and

a spring disposed between the spring supporting portion and the stop member.

23. A latching system according to claim 22, wherein the spring elastically biases the latch release member towards the plurality of receiving lock members and pulling the latch release mechanism disengages the plurality of upper latches from the respective upper arm to allow the plurality of lower latches to pivot.

24. A latching system according to claim 22, wherein the housing further comprises:

a plurality of side walls; and

a plurality of divider panels, each of the plurality of divider panels set apart from one of the plurality of side walls to form a side channel therebetween,

wherein each of the plurality of pivot supports are disposed within the one of the side channels to receive the pivot of one of the plurality of lower latches, the stop member is disposed at a distal end of one of the plurality of side channels, and the spring is disposed between the spring supporting portion and the stop member.
