Rise up table top

摘要

A lightweight and portable table that during its use can be set upon a desk or another table, and which has an upwardly extendable top surface with a maximum elevation of approximately one foot. It allows people working in a seated position at their desk to adjust the working top surface thereof to a more comfortable position, and alternatively allow them to comfortably work from the elevated top surface while in a standing position. The portable table is easy to manage, movable from one support surface to another with little effort, spring-assisted with load during up and down deployment, and it promotes improved health and welfare of its users. Applications include, but are not limited to, home use, business use, and use by healthcare workers who need prompt access to instruments and devices while in both sitting and standing positions when caring for different patients during a work day.

1. A portable and elevation-adjustable table top assembly placed on top of a horizontally-extending surface to provide its users with health and comfort advantages, said table top assembly comprising:
a table top surface with a front portion, a rear portion, and opposed sides; two pairs of lifters centrally and rotatably joined to one another forming an X-shaped configuration, each said lifter having a top end and a bottom end, and each of said pairs of lifters associated with a different one of said opposing sides of said table top surface in positions creating two sets of laterally opposed lifter top ends and two sets of laterally opposed lifter bottom ends; two top rails each associated with a different one of said opposing sides of said table top surface, each said top rail also connected to a different one of said two sets of laterally opposed lifter top ends, and each said top rail also having an elevation-adjusting slot; two base rails having spaced-apart positioning under and between said opposed sides of said table top surface, said base rails each having an elevation-adjusting slot, and said base rails each also connected to a different one of said two sets of laterally opposed lifter bottom ends; five axis rods, two of said axis rods connected between said base rails with one of said axis rods connected between said two elevation-adjusting slots in said base rails, two additional ones of said axis rods connected between said top rails with one of said axis rods connected between said two elevation-adjusting slots in said top rails, and the fifth one of said axis rods connected between said opposed pairs of said lifters where said lifters in each said pair are centrally and rotatably joined forming an X-shaped configuration; two spaced-apart locking bars associated with said table top surface, each said locking bar positioned adjacent to a different one of said top rails; two locking rods having spaced-apart positioning between said locking bars; and two locking handles, each positioned near a different one of said opposed sides of said table top surface and engaging a different one of said locking bars, wherein when said locking handles are moved to release said locking bars, said table top surface can be movable vertically to a new elevation between a maximum extended configuration and a minimum collapsed configuration.
