  • Patent number: 6327985
    Abstract: In order to simplify an arrangement of a desk which can integrate a mechanism to adjust a height of a top plate and a mechanism to adjust a level of a top plate, in a desk in which a height of a top plate can be varied within a predetermined range through a height adjust mechanism, the desk is so arranged that the top plate is supported by a plurality of expansible leg support posts, and the height adjust mechanism makes use of the leg support posts and can adjust an expansile amount of the leg support posts individually within the predetermined range through a little larger than the predetermined range.

  • Patent number: 6302037
    Abstract: A demountable component table system to improve handicapped access to standard proportioned furnitures common to public places. A table top component has symmetrically positioned cut-outs for foam rubber covered, demountable flexible steel rods to pass from their frame component sockets upwards to the area above the top component where they provide upper body and arm support for occupant utilization and management of the cubic space above the table top. Frame mounted rods with Velcro attachments and a vertically mounted rigid tubular pole which inserts through the table top component into its socket mount in the table frame allow for customized positioning of objects in the cubic space above the top. The front side edge of the top component is cantilevered towards the occupant's chest. Varied types of demountable legs allow for height adjustment in inch increments.

  • Patent number: 6286441
    Abstract: A motorized height adjustable table having a support base, a top assembly including a substantially horizontally disposed work surface, and first and second powered drive assemblies for raising and lowering the work surface. The first and second drive assemblies have first and second electric motors and drivingly engage the top assembly for effecting vertical movement of the top assembly to adjust the height of the work surface. A controller is coupled to the first and second drive assemblies for simultaneously controlling the first and second electric motors. The controller senses a relative height displacement between the first and second drive assemblies and de-energizes the motor controlling for the leading drive assembly until the relative difference in height between the first and second drive assemblies is substantially zero.

  • Patent number: 6250594
    Abstract: A device to adjust the height of panels, more particularly, the height of working tables includes at least one console (12) which is mounted to a stand and fitted with at least two vertical translational lifting elements (14). A lid or cover (13) is screwed on the console (12). An opening is formed between the console (12) and the lid or cover (13) which is adapted to receive a profile section of a frame. The profile section is clamped between the lid and the console when the lid is screwed to the console. The lifting elements (14) are located in holes (121) in the console (12). The lifting elements (14) are inserted in the holes (121) in such a way that they can not rotate.
