Abstract

A platform system is configured to allow an individual to be supported at a plurality of different heights, and includes a frame defining a plurality of platform adjustment levels, and an upper support platform that is configured to be selectively moved between the plurality of platform adjustment levels to provide the plurality of different heights.

First claim

What is claimed is:

1. A platform system that is configured to allow an individual to be supported at a plurality of different heights, the platform system comprising:
a frame defining a plurality of platform adjustment levels, the frame including a first post, a second post, a third post, and a fourth post;
an upper support platform that is configured to be removed and reinserted into any of the plurality of platform adjustment levels to provide the plurality of different heights;
a base step moveably coupled and secured to the frame, wherein the base step is below the upper support platform, wherein the base step is configured to be outwardly moved between a fully retracted position within the frame and a fully extended position in relation to the frame, and wherein the base step is configured to support the individual in the fully extended position; and
a support tray pivotally coupled between the third post and the fourth post of the frame, wherein the support tray includes a pivot bracket pivotally coupled to interior portions of the third post and the fourth post through one or more pivot pins, the support tray pivotable into an extended position about one of the pivot pins and locked in the extended position by at least one bracing lock, at least one locking pin configured to be removably coupled at different heights along the third post and the fourth post, so that the support tray is adjustable to various different levels along the third post and the fourth post.

2. The platform system of claim 1 , wherein the plurality of platform adjustment levels comprise a first platform adjustment level and a second platform adjustment level, wherein the upper support platform is configured to be completely removed from the first platform adjustment level and inserted into the second platform adjustment level.

3. The platform system of claim 1 , wherein the plurality of platform adjustment levels comprise a first platform adjustment level and a second platform adjustment level, wherein the first platform adjustment level is spaced from the second platform adjustment level that is adjacent to the first platform adjustment level a distance of two inches.

4. The platform system of claim 1 , wherein the base step includes a handle that is configured to be grasped, wherein the handle is formed on a support surface of the base step, and wherein the support surface is configured to support the individual.

5. The platform system of claim 1 , further comprising a moveable intermediate transition step underneath the upper support platform.

6. The platform system of claim 5 , wherein the intermediate transition step is moveably coupled to the base step through at least one pivotal link.

7. The platform system of claim 5 , wherein the intermediate transition step upwardly extends when the base step is in the fully extended position.

8. The platform system of claim 1 , wherein the frame includes a plurality of rails, wherein the plurality of platform adjustment levels are defined between the plurality of rails.

9. The platform system of claim 1 , further comprising casters connected to the frame, wherein the casters are configured to allow the platform system to be moved to different locations.

10. The platform system of claim 9 , further comprising handles extending from the frame, wherein the handles are configured to be grasped to tilt the platform system onto the casters.

11. The platform system of claim 10 , wherein at least one of the plurality of beams comprises a moveable safety beam that is configured to be moved between closed and open positions, wherein the safety beam is pivotally coupled to the first post of the frame and removably coupled to the second post of the frame, wherein the safety beam is coupled to the first post and the second post in the closed position, and wherein the safety beam is connected to the first post and decoupled from the second post in the open position.

12. The platform system of claim 1 , wherein the frame comprises a plurality of beams that provide barriers that restrain movement of the individual.

13. The platform system of claim 1 , wherein the support tray defines an open channel that is configured to receive a container.

14. The platform system of claim 1 , wherein the plurality of platform adjustment levels comprise twelve platform adjustment levels.

15. A platform system that is configured to allow an individual to be supported at a plurality of different heights, the platform system comprising:
a frame including a plurality of rails defining a plurality of platform adjustment levels, and a plurality of beams that provide barriers that restrain movement of the individual, wherein at least one of the plurality of beams comprises a moveable safety beam that is configured to be moved between closed and open positions, wherein the plurality of platform adjustment levels comprise a first platform adjustment level and a second platform adjustment level, wherein the safety beam is pivotally coupled to a first post of the frame and removably coupled to a second post of the frame, wherein the safety beam is coupled to the first post and the second post in the closed position, and wherein the safety beam is connected to the first post and decoupled from the second post in the open position;
casters connected to the frame, wherein the casters are configured to allow the platform system to be moved to different locations;
handles extending from the frame, wherein the handles are configured to be grasped to tilt the platform system onto the casters;
a support tray pivotally coupled between a third post and a fourth post of the frame, wherein the support tray includes a pivot bracket pivotally coupled to interior portions of the third post and the fourth post through one or more pivot pins, the support tray pivotable into an extended position about one of the pivot pins and locked in the extended position by at least one bracing lock, at least one locking pin configured to be removably coupled at different heights along the third post and the fourth post, so that the support tray is adjustable to various different levels along the third post and the fourth post;
an upper support platform that is configured to be removed and reinserted into any of the plurality of platform adjustment levels to provide the plurality of different heights, wherein the upper support platform is configured to be completely removed from the first platform adjustment level of the frame and inserted into the second platform adjustment level of the frame;
a base step moveably coupled and secured to the frame, wherein the base step is below the upper support frame, wherein the base step is configured to be outwardly moved between a fully retracted position within the frame and a fully extended position in relation to the frame, wherein the base step is configured to support the individual in the fully extended position; and
a moveable intermediate transition step underneath the upper support platform, wherein the intermediate transition step is moveably coupled to the base step through at least one pivotal link, wherein the intermediate transition step upwardly extends when the base step is in the fully extended position.

16. The platform system of claim 15 , wherein the first platform adjustment level is spaced from the second platform adjustment level that is adjacent to the first platform adjustment level a distance of two inches.

17. The platform system of claim 15 , wherein the base step includes a grasp handle formed on a support surface of the base step, and wherein the support surfa
