  • Patent number: 9861220
    Abstract: A moveable anti-fatigue mat that can be moved by a user's foot without the need for the user to bend over. In one embodiment, the anti-fatigue mat comprises a cushioned top layer affixed to a high friction bottom layer, wherein a low friction activation pad is positioned on or within the bottom layer. The activation pad can be attached so that a bottom surface protrudes below or is flush with the bottom surface of the bottom layer, and the activation pad is preferably located near the edge of the bottom layer. The anti-fatigue mat may be slid laterally on a floor or surface by a user's foot when a user places his foot on the mat directly above the activation pad and applies pressure downward and in the direction the user wishes the mat to move.

  • Publication number: 20130014675
    Abstract: A height adjustable desktop apparatus including a work surface that may be adjusted between a raised and a lowered position, as well as any desired intermediate position, is provided. The work surface moves upwardly and downwardly in a vertical direction, and is supported by a pair of hinged support members. The hinged support members are pivotally attached, on a top portion, to the underside of the work surface, and one or both may be attached on a bottom portion to a sliding base member, which slides in a horizontal, lateral direction. The apparatus includes a fixed hutch, preferably having a fixed base member and a pair of fixed, raised shelves, wherein each shelf is supported by a pair of fixed vertical support members. The sliding base member is slidably attached to the fixed base member of the hutch, and moves in a lateral, sideways direction during adjustment.
