Height-adjustable support surface and system for encouraging human movement and promoting wellness
First Claim
1. A sit-stand desk, comprising:
- a frame located on a floor surface;
a panel having an upper work surface and being selectively vertically displaceable with respect to the frame;
a vertical-displacement drive mechanism mechanically connected between the frame and the panel, wherein activation of the drive mechanism vertically displaces the panel with respect to the frame;
a processor selectively activating the drive mechanism to vertically displace the panel according to prescribed displacement instructions in response to receipt of a trigger signal; and
a sensor in communication with the processor and configured to detect activity within at least first and second different space zones located vertically below the panel; and
wherein the processor is configured to determine a frequency of user movement within the first and second zones based on input from the sensor and wherein timing of the trigger signal is based at least in part on changes in the frequency.

Abstract
A sit-stand desk includes a frame located on a floor surface; a panel having an upper work surface and being selectively vertically displaceable in respect to the frame; and a vertical-displacement drive mechanism mechanically connected between the frame and the panel. Activation of the drive mechanism vertically displaces the panel with respect to the frame. The sit-stand desk also includes a control circuit selectively activating the drive mechanism to vertically displace the panel according to prescribed displacement instructions in response to receipt of a trigger signal and a pressure mat located on the floor surface adjacent to the frame on which a user stands. The pressure mat includes a pressure sensor in communication with the control circuit and configured to measure a presence of the user adjacent to the desk.

16. A sit-stand desk, comprising:
-
a frame supported on a floor surface; a substantially flat panel member supported by the frame, having an upper work surface, and being selectively vertically displaceable with respect to the frame, the panel having a front edge, lateral first and second side edges and a front portion adjacent the front edge, a first space zone including space directly below the front portion and between the first and second side edges of the panel member as well as space extending away from the front edge in a direction opposite the space directly below the front portion that is occupied by a desk user when in a standing or sitting position adjacent the front edge; a vertical-displacement drive mechanism mechanically connected between the frame and the panel member, wherein activation of the drive mechanism vertically displaces the panel member with respect to the frame; a processor selectively activating the drive mechanism to vertically displace the panel member according to prescribed displacement instructions in response to receipt of a trigger signal; and at least a first sensor in communication with the processor and configured to detect user movement within at least the first zone, the at least a first sensor being one of a non-contact proximity sensor and a thermal sensor. - View Dependent Claims (17, 18, 19)
