Abstract

A quick connect joint includes a base with first and second lock receivers on opposite sides of the base, and a connection plate including first and second engagement members engageable with the first and second lock receivers, respectively. The first engagement member is displaceable between a release position and lock position, and the first engagement member is rotatable between an insert position and a connect position. The quick connect joint creates a safe and reliable connection.

Claims

1. A quick connect joint for connecting a first part to a second part, the quick connect joint comprising:

a base securable to the first part, the base including an engaging surface with a T-bar slot defined in the engaging surface, and the base including a tab opening defined by a bracket extending from the engaging surface;

a connection plate securable to the second part, the connection plate including a tab member engageable with the bracket in the tab opening of the base; and

a cam latch extending through the connection plate, the cam latch including a cam actuator on one side of the connection plate coupled with a T-bar and a T-bar shaft on an opposite side of the connection plate, wherein the T-bar shaft is positionable in the T-bar slot with the T-bar on a side of the base opposite from the engaging surface, and wherein the cam actuator is displaceable between a release position in which the T-bar is disengaged from the base and a lock position in which the T-bar is engaged with the base.

2. A quick connect joint according to claim 1, wherein the cam actuator is rotatable between an insert position in which the T-bar is aligned with a longitudinal axis of the T-bar slot and a connect position in which the T-bar is not aligned with the longitudinal axis of the T-bar slot.

3. A quick connect joint according to claim 1, wherein one of the base and the connection plate comprises an insert member, and wherein the other of the base and the connection plate comprises an insert opening, the insert member engaging the insert opening when the connection plate is coupled with the base.

4. A quick connect joint according to claim 1, wherein the bracket defining the tab opening is integral with the base.

5. A quick connect joint according to claim 1, wherein the tab member includes a groove on an upper surface, the groove being engageable with the bracket.

6. A quick connect joint according to claim 1, wherein the base comprises a base socket with internal threads for connecting to the first part, and wherein the connection plate comprises a connection plate socket with internal threads for connecting to the second part.

7. A quick connect joint according to claim 1, wherein the tab and the cam latch are positioned on opposite sides of the connection plate.

8. A quick connect joint according to claim 1, wherein the cam actuator comprises a cam handle coupled with a cam member, and wherein the cam latch further comprises a cam insert positioned between the cam member and the connection plate and engaged with the cam member, the cam member and the cam insert being cooperatively shaped such that rotation of the cam member relative to the cam insert draws the T-bar shaft and the T-bar toward the cam member.

9. A quick connect joint according to claim 1, wherein the connection plate comprises a seal on an underside thereof facing the engaging surface of the base.

10. A quick connect joint according to claim 1, wherein the base comprises at least one pad secured on the engaging surface.

11. A method of securing a quick connect joint including a base with a T-bar slot and a tab opening, a connection plate with a tab member, and a cam latch extending through the connection plate and including a cam actuator on one side of the connection plate coupled with a T-bar and a T-bar shaft on an opposite side of the connection plate, the method comprising:

(a) inserting the tab member of the connection plate into the tab opening of the base;

(b) with the cam latch in a release position, pivoting the connection plate into engagement with the base and inserting the T-bar shaft into the T-bar slot; and

(c) displacing the cam latch from the release position to a lock position to thereby draw the T-bar into engagement with the base.

12. A method according to claim 11, wherein step (b) is practiced with the cam actuator in a release position such that the T-bar is aligned with a longitudinal axis of the T-bar slot, the method further comprising, before step (c), rotating the cam actuator from the release position to a connect position in which the T-bar is not aligned with the longitudinal axis of the T-bar slot.

13. A method according to claim 12, further comprising engaging a groove in an upper surface of the tab with the tab opening in the base.

14. A method according to claim 11, further comprising sealing the engagement between the connection plate and the base.

15. A method according to claim 11, wherein one of the base and the connection plate comprises an insert member, and the other of the base and the connection plate comprises an insert opening, and wherein step (b) further comprises engaging the insert member with the insert opening.

16. A quick connect joint comprising:

a base including first and second lock receivers on opposite sides of the base; and

a connection plate including first and second engagement members engageable with the first and second lock receivers, respectively,

wherein the first engagement member is displaceable between a release position and lock position.

17. A quick connect joint according to claim 16, wherein the first engagement member is rotatable between an insert position and a connect position.

18. A quick connect joint according to claim 17, wherein the base comprises a cylindrical insert member protruding from an engaging surface of the base, and wherein the connection plate comprises an insert opening sized to receive the insert member, the insert member engaging the insert opening when the connection plate is engaged with the base.

19. A quick connect joint according to claim 17, wherein the first engagement member comprises a cam latch extending through the connection plate, the cam latch including a cam actuator on one side of the connection plate coupled with a T-bar and a T-bar shaft on an opposite side of the connection plate, wherein the T-bar shaft and the T-bar are engaged with the first lock receiver when the cam actuator is displaced to a lock position.

20. A quick connect joint according to claim 17, wherein the connection plate comprises a seal on an underside thereof facing the base.

21. A quick connect joint according to claim 16, wherein the second engagement member comprises a tab member, and wherein the second lock receiver comprises a tab opening defined by a bracket.

22. A quick connect joint according to claim 21, wherein the bracket comprises posts extending from the base and a cross bar secured on the posts.

23. A quick connect joint according to claim 16, wherein the first lock receiver comprises a cam groove, and wherein the first engagement member comprises a cam engageable with the groove in the lock position.

24. A quick connect joint according to claim 23, wherein the first engagement member comprises the cam disposed at a distal end of a rotatable lever.

25. A quick connect joint according to claim 24, wherein the connection plate comprises a plate pair disposed on opposite sides of the rotatable lever and including through holes, and wherein the lever comprises a locking hole that is positioned in alignment with the through holes in the plate pair in the lock position.
