Abstract

A rotatable seat mount apparatus is disclosed. A disclosed apparatus includes a seat mount having a locking arm pivotally mounted within the seat mount. A lever is rotatably coupled to the locking arm so that rotation of the lever causes the locking arm to pivot from a first position in which the seat mount is prevented from rotating and to a second position in which the seat mount is enabled to rotate.

Claims

1. A rotatable seat mount apparatus, comprising:

a seat mount;

a locking arm pivotally mounted within the seat mount; and

a lever rotatably coupled to the locking arm, wherein rotation of the lever causes the locking arm to pivot from a first position in which the seat mount is prevented from rotating and to a second position in which the seat mount is enabled to rotate.

2. An apparatus as defined in claim 1, wherein the lever comprises a cam to pivot the locking arm from the first position to the second position.

3. An apparatus as defined in claim 1, wherein the seat mount is to be rotatably coupled to a pedestal.

4. An apparatus as defined in claim 1, further comprising a tubular member extending from the seat mount, the tubular member having a first slot located at an upper end of the tubular member and a second slot located at a lower end of the tubular member.

5. An apparatus as defined in claim 4, wherein the locking arm is to be pivotally mounted within the tubular member and having a locking tab to engage the second slot.

6. An apparatus as defined in claim 4, wherein the tubular member is to be rotatably coupled to a pedestal.

7. An apparatus as defined in claim 1, wherein rotation of the lever from the first position to the second position causes the locking arm to remain in the second position, and rotation of the lever from the second position to the first position causes the locking arm to remain in the first position.

8. An apparatus as defined in claim 1, wherein the first position is associated with a locked condition in which the seat mount is prevented from rotating and the second position is associated with an unlocked condition in which the seat mount is enabled to rotate.

9. An apparatus as defined in claim 1, wherein the lever is pivotally coupled to the locking arm, and wherein the lever is urged to a third position when a lifting force is applied to the lever and urged to a fourth position when the lifting force is released from the lever.

10. An apparatus as defined in claim 9, wherein the third position is associated with an unlocked condition in which the seat mount is enabled to rotate and the fourth position is associated with a locked condition in which the seat mount is prevented from rotating.

11. An apparatus as defined in claim 9, further comprising a biasing member operatively coupled to the locking arm to bias the locking arm toward the fourth position when the lifting force is released from the lever.

12. A rotatable seat mount apparatus, comprising:

a seat mount;

a tubular member extending from the seat mount and having a first opening located at an upper end of the tubular member and a second opening located at a lower end of the tubular member;

a sleeve to receive at least a portion of the tubular member and to be rotatably coupled to a base, wherein the sleeve has a third opening located at an upper end of the sleeve and a fourth opening located at a lower end of the sleeve, wherein the first opening is to be in communication with the third opening and the second opening is to be in communication with the fourth opening;

a latch operatively mounted within the tubular member;

a lever having a curved surface adjacent a first end and a grip adjacent a second end such that rotation of the grip and the curved surface causes the latch to move between a first position in which the seat mount is prevented from rotating relative to the base and a second position in which the seat mount is enabled to rotate relative to the base.

13. An apparatus as defined in claim 12, wherein rotation of the lever from the first position to the second position causes the latch to remain in the second position, and rotation of the lever from the second position to the first position causes the latch to remain in the first position.

14. An apparatus as defined in claim 12, wherein the latch has a protrusion to engage the second and fourth openings.

15. An apparatus as defined in claim 12, wherein the latch is pivotally mounted to the lever and within the tubular member.

16. An apparatus as defined in claim 12, further comprising a cap having elongated sides, wherein the latch is pivotally mounted to the cap.

17. An apparatus as defined in claim 16, wherein the cap is mounted to the seat mount.

18. An apparatus as defined in claim 12, wherein the lever is pivotally mounted to the latch such that a lifting force applied to the lever causes the latch to pivot from the first position to the second position.

19. An apparatus as defined in claim 18, further comprising a biasing member operatively coupled to the latch to bias the latch toward the first position when the lifting force is released from the lever.

20. An apparatus as defined in claim 19, wherein the biasing member is a spring.

21. An apparatus as defined in claim 12, wherein the lever comprises a stem and a handle.

22. An apparatus as defined in claim 21, wherein the handle slidably receives the stem.

23. An apparatus as defined in claim 21, wherein the handle and the stem are operatively and rotationally coupled to the latch.

24. An apparatus as defined in claim 21, wherein rotation of the handle causes the latch to move between the first position and the second position.

25. An apparatus as defined in claim 12, wherein the sleeve is to be removably mounted to the base.

26. An apparatus as defined in claim 12, wherein an inner surface of the sleeve comprises a plurality of vertical ribs.
