A multifunctional computer stand, including a symmetrically arranged push shaft, outer wall of the push shaft is movably connected with a connecting rod, and the left and right sides of push shaft are respectively connected with a first and a second rotating rod. Outer wall of connecting rod is rotatably connected with a plurality of geared fixing seats, right side of second rotating rod is provided with a plurality of limit rings, and buttons are slidably connected in limit rings. A first button and a second button are provided with a gear shaft on the lower side, a spring is fixed on the bottom surface of the gear shaft, and the other end of the spring is fixedly connected with the end surface of the connecting rod so the inner walls of the first and the second rotating rod are provided with limit teeth that mesh with the gear shaft.

Described are a height adjust stand (HAS) for a display and an all in one computing device. The HAS includes a base. A riser assembly connects to the base, and angled greater than 90 degrees from vertical of the HAS. A lift plate in the riser assembly that includes an arm, the arm angled greater than 90 degrees from vertical of the HAS. The lift plate provides vertical travel for the display. A VESA assembly includes a mating component that fits into the opening of the arm. The VESA assembly including an internal hinge that provides tilt for the display. In an all in one computing device, a computing cartridge assembly is snapped into the back of the riser assembly.

A workpiece turntable comprises a turntable module and an attachable floor-engaging support. The floor-engaging support is preferably height adjustable. The turntable module comprises a rotatable base mounted on a stationary base; a wire frame mounted over the rotatable base; a first set of support elements extending from the wire frame having a first height relative to the rotatable base; and a second set of support elements extending from the wire frame having a second height relative to the rotatable base. Each one of the support elements includes a respective support finger that can be made of an elastomer such rubber, silicone, or urethane.

A joint for furniture uses alternating tabs and slots formed along an edge of first and second furniture panels. The panels are joined together so that tabs in the first panel are disposed in slots in the second panel and tabs in the second panel are disposed in slots in the first panel. This arrangement causes the slots to flex outwardly and the tabs to flex inwardly once assembled and creates residual stress in the assembled joint which stiffens the joint.

A vacuum sucker is installed on a robotic arm to suck an object. The robotic arm includes a body and a tip axis. The tip axis is disposed with an adapter plate. The vacuum sucker includes a housing, an actuator, and a flexible suction cup. The actuator passes through the housing and includes a main part, a thrust rod, and an elastic element. The main part has a first end and a hollow slot. The flexible suction cup is sleeved on the first end and is formed with an air chamber. When the thrust rod is located at the first position, the air chamber and the hollow slot are not intercommunicated with each other. When the thrust rod is driven by the adapter plate to move to a second position, the air chamber and the hollow slot are intercommunicated with each other.

A height adjustable monitor arm assembly includes a monitor arm having a latch mechanism where a post arm includes indented rings therein for engaging the latch mechanism. The monitor arm includes an aperture for positioning the at least one monitor arm over the post arm so that the latching mechanism engages with one of the plurality of indented rings to vertically adjust the at least one monitor arm along the length of the post arm. Further, a dual adapter arm also includes its own latching mechanism and mounts over the vertical post arm for use where monitor displays can be mounted on both ends thereof. In one embodiment, a four monitor configuration can be held in position allowing for enhanced user utility in their workspace.
