Variable height platform system
First Claim
1. A variable height platform system comprising:
- a frame assembly extending longitudinally along a longitudinal axis, the frame assembly configured to support and to be removably connected to one of a plurality of different tabletops, the frame assembly configured to be adjustable along the longitudinal axis to accommodate the plurality of different tabletops,wherein the size of a first of the plurality of different tabletops is different from the size of a second of the plurality of different tabletops;
at least two leg assemblies, each leg assembly configured to be pivotally connected to a portion of the frame assembly, each leg assembly configured to be movable betweena deployed position in which each leg assembly is configured to be substantially perpendicular to the longitudinal axis of the frame assembly so as to support the frame assembly in an elevated position for use, anda storage position in which each leg assembly is configured to be folded flat against the frame assembly and essentially parallel to the longitudinal axis of the frame assembly,a drive mechanism configured to either extend or retract each leg assembly in a direction substantially perpendicular to the longitudinal axis to set a height of the frame assembly in the elevated position; and
a connector assembly disposed on the frame assembly and configured to detachably lock one of the plurality of different tabletops to the frame assembly,wherein the plurality of different tabletops are interchangeable such that the first of the plurality of different tabletops, detachably locked to the frame assembly by the connector assembly, is removed from the frame assembly by unlocking the connector assembly, the frame assembly is then adjusted along the longitudinal axis to accommodate the second of the plurality of different tabletops, and the second of the plurality of different tabletops is positioned on the frame assembly and detachably locked to the frame assembly by the connector assembly,wherein a thickness of the first of the plurality of different tabletops is different from a thickness of the second of the plurality of different tabletops, and wherein the thicknesses of the first and the second of the plurality of different tabletops are measured perpendicular to the longitudinal axis, andwherein the connector assembly is configured to be adjustable, in the direction along which each leg assembly either extends or retracts, to accommodate the different thicknesses of the first and the second of the plurality of different tabletops.

Abstract
A variable height platform system comprises a frame assembly, at least two leg assemblies, a drive mechanism, and a sensor. The frame assembly is configured to support and be removably connected to a tabletop. The drive mechanism is configured to either extend or retract each leg assembly in a direction substantially perpendicular to the longitudinal axis to set a height of the frame assembly in an elevated position for use. The sensor is configured to sense position and movement of a user in a predetermined area including an area of the variable height platform system and an area proximate the variable height platform system. The controller is operatively connected to the sensor and drive mechanism. The controller is configured to operate the drive mechanism in response to the sensor sensing the position and movement of the user in the predetermined area.
