Abstract

portable stage (200) including a removable deck (104) including a vertical through hold (136) supported on a frame. The frame has a vertical column (118) which support the deck on the ground. A height adjustment assembly (160) is mounted on the vertical column. The height adjustment assembly includes a threaded bushing (162), a movable socket (166), and a rod (164) which is attached to a pin (164) which is inserted from underneath the deck into the vertical through hole. The deck is supported on the socket, and rotating the pin raises the socket and associated deck. The current device allows the stage height to be easily adjusted from above.

Claims

WHAT IS CLAIMED IS:

1. A portable stage comprising: a deck having a planar first face and an opposite planar second face, a 5 through hole extending vertically through the deck between the first face and the second face; a frame below the deck , the frame supporting the portable stage on a surface and having a vertical column extending to the surface; a pin slidably and removably extending upward into the through hole a fixed 10 distance and having a top engagement portion configured to be engaged from above through the through-hole; and a height adjustment assembly mounted on the vertical column of the frame, the height adjustment assembly comprising a bushing configured to mount in the vertical column, an axially movable socket, and a rod and attached to an underside 15 of the pin, the rod threadably engaging the bushing, wherein rotation of the pin and the attached rod relative to the socket and the bushing axially moves the socket relative to the bushing, the deck being removably supported on the socket, the height adjustment assembly raising the socket and the deck upon rotation of the pin in a first direction, 20 wherein the pin is insertable from below into the through-hole from either the first face or the second face of the deck and the deck is mountable onto the pin, wherein a portion of one of the first face or the second face of the deck proximate the through-hole faces downward and is resting on the height adjustment 25 assembly with the other of the first face or the second face of the deck forming an upper surface.

2. A portable stage according to claim 1, wherein the height adjustment assembly lowers the deck upon rotation of the pin in a second direction.

3. A portable stage according to any preceding claim, wherein the top engagement portion comprises a tool engagement recess at an upper surface of the 5 pin and configured for engagement from above by a complementary tool extending through the through-hole.

4. A portable stage according to any preceding, further comprising a sliding insert in the through-hole engaging a top of the pin and defining a passage aligned with a top of the pin. 10

5. A portable stage according to any preceding claim, further comprising an end cap at each end of the through-hole proximate the first face and the second face, the end caps retaining the sleeve in the through-hole, the end cap having a center opening.

6. A portable stage according to any preceding claim, further comprising a 15 sleeve slidably retained in the through hole between a first position proximate the first face and a second position proximate the second face, the sleeve engaging a top of the pin.

7. A portable stage according to any preceding claim, wherein the stage comprises a plurality of the decks and wherein the height adjustment assembly 20 comprises a plurality of pins is configured for supporting the plurality of the decks.

8. A portable stage according to any preceding claim, wherein the upper surface of the deck is unobstructed.

9. A portable stage according to any preceding claim, comprising a pin connector assembly, the pin connector assembly including a plurality of further pins.

10. A portable stage according to claim 9, wherein the further pins of the pin connector assembly are spaced and configured for extending into a corresponding through-hole.

11. A portable stage according to claim 10, wherein the further pins are rotatably 5 mounted to move between a lowered position and a raised position.

12. A portable stage according to claim 11, wherein the further pins extend substantially horizontally in the lowered position and the further pins extend vertically in a raised position on arms extending from a housing.

13. A portable stage according to claim 12, wherein the housing is rotatably 10 mounted for positioning one or more of the arms below the deck.

14. A portable stage according to claim 9 wherein the pin connector assembly includes three arms extending from a housing, each of the arms having a further pin mounted thereon; the further pins being spaced to extend into through holes of further decks and support a corner of the further decks.

15.15. A portable stage according to claim 14, wherein the further pins are rotatably mounted on the arms to move between a lowered position in which the further pins extend substantially horizontally and a raised position in which the further pins extend vertically.

16. A portable stage according to claim 14, wherein the housing and each of the 20 pins are rotatably mounted for positioning one or more of the arms below the deck.

17. A portable stage according to claim 1, further comprising a release assembly for positioning the pin connector assembly at a selected orientation.

18. A portable stage according to claim 17, wherein the release assembly includes a handle, a pin and a spring, the pin selectively extending through a 25 corresponding orifice in the housing.
