Abstract: An adjustable height table base assembly includes two or more leg assemblies each including a mobile leg member, a stationary leg member, and a linear motion system. The mobile and stationary leg members are each formed of a flat vertical support structure. The leg assemblies are configured to extend and retract to adjust a height position of the mobile leg member and any table top secured to the mobile leg member. The mobile leg members slide in a parallel direction in relation to the stationary leg members by means of linear motion systems. The power mechanism for the adjustable height table may comprise a counterbalance mechanism or one or more electric motors. Optionally, each of the leg assemblies also includes a non-load bearing cover enclosing at least a portion of the mobile leg member and at least a portion of the stationary leg member.

Abstract: A height adjustable workstation for positioning a monitor and a keyboard relative to a work surface. The height adjustable workstation can include a stationary column positioned below the work surface and a movable column coupled to the stationary column and vertically extendable above the work surface. The movable column can support a keyboard support and/or a monitor mount. A counterbalance assembly, which is positioned below the work surface and operatively coupled to both the stationary column and movable column, functions to offset the load carried by the keyboard support and/or monitor mount to provide effortless height adjustment.

Abstract: A band brake suitable for use with height adjustable tables and configured to selectively grip and release a lift band utilized by the table's height adjusting mechanism to raise and lower the work surface. The band brake may include an eccentric roller configured to move between a band-engaged position and a band-disengaged position. A release lever is connected to the eccentric roller and configured to transition the eccentric roller between the band-engaged and the band-disengaged positions. A linkage system is connected between the brake housing and the release lever, whereby the linkage system counteracts torque created by a release spring operating on the release lever.

Abstract: An adjustable support arm utilizing an elastomeric member having a dynamic attachment point to support the weight of an attached object. The adjustable support arm can include a lower bracket that is connected to an upper bracket by an upper arm and a lower arm. The elastomeric member counterbalances the weight of an attached object. The first end of the elastomeric member can be attached to a linkage, which can include a first, second, and third link and the second end of the elastomeric member can be attached to one of the arms. The links can be coupled to each other between the upper and lower arms such that the linkage is dynamically moveable upon movement of the support arm.
