A table dedicated to facilitating the comfort, efficacy, and enjoyment of assembling a jigsaw puzzle which may be adjusted for height, tabletop tilt angle and tabletop rotation, and location. The table has a specialized surface to hold the puzzle pieces in place, an accessory bracket to add accessories such as trays, puzzle box top holder, magnifying glass and other implements to enhance the assembly experience. Trays for sorting puzzle pieces may be attached and detached from a specialized bracket mounted on a support structure. The tabletop may be positioned high enough to be used while standing upright. The use of this table apparatus for other activities is anticipated.

A screw rod self-locking device includes a one-way bearing and a mounting seat, and an inner hole of the one-way bearing is sleeved at an end of a screw rod. A mounting hole for receiving the one-way bearing is disposed on the mounting seat, and the one-way bearing is rotatably fitted into the mounting hole along a circumferential direction. An adjusting mechanism for adjusting a circumferential locking force of the mounting hole for the one-way bearing is disposed on the mounting seat so as to adjust a size of a friction force between an outer wall of the one-way bearing and an inner wall of the mounting hole. A height-adjustable leg and a height-adjustable desk applying the same are further provided. In this way, a size of a self-locking friction force to be overcome during backward rotation of a screw rod can be self-defined, thereby guaranteeing consistency of product performances.

A table may include one or more tap gesture-activated light indicators that appear on a top surface of the table. The one or more light indicators may indicate a location of one or more wireless charging areas on the top surface of the table. The one or more light indicators may also indicate a location of one or more control elements (e.g., for controlling a height of the table). In a height-adjustable version of the table, each of the height-adjustable legs may include a linear actuator and a telescopic enclosure with a plurality of bulbous members. Additionally, a pressure sensitive surface of the table may measure a pressure pattern generated by a body part of the user resting on the pressure sensitive surface, and a machine learning algorithm infer a posture of the user based on the pressure pattern, and suggest a corrective measure in response to poor posture.

The present application relates to a lifting column for a piece of furniture, in particular for a table. The lifting column comprises a first element and also a second element. The second element is introduced at least some way into the first element. The first element has a spindle, which extends along the longitudinal axis of the first element and projects at least some way into the second element. The second element has a rotor, which is mounted in a rotatable manner in it and has at least one rolling body, which runs in or on a thread helix of the spindle. A rotation of the rotor relative to the spindle gives rise to a linear movement of the second element relative to the first element. The second element also has an arresting device, which, in a first state, blocks the rotation of the rotor relative to the spindle and, in a second state, frees the rotation of the rotor relative to the spindle. At least one leg spring is clamped in between the rotor and a fastening element, which is fastened on the second element, and this leg spring therefore subjects the rotor to a prestressing force.

A height-adjustable table including a length-adjustable support, a motor assembly configured to drive adjustment of the length-adjustable support, a motor housing supporting the motor assembly. The length-adjustable support includes a telescopic column assembly comprising an exterior tube, an interior tube, and a spindle assembly. The spindle assembly includes spindle rod fixedly coupled to a first end of the exterior tube, the spindle rod being threadingly engaged with a spindle guide coupled to a first end of the interior tube, whereby rotation of the spindle rod causes the distance between the first ends to change in order to telescope the interior tube into or out of the exterior tube. Illustratively, force from rotation of the spindle rod is transferred through the spindle guide and into the first end of the interior tube. In illustrative embodiments, the spindle guide may extend through an aperture of a support plate coupled to the first end of the interior tube, thereby permitting transfer of force from the spindle rod to the interior tube.

A workstation and furniture combination is provided. The combination is enabled with height adjustability of a top surface and via a concealed power source that also provides concealed charging of electrical devices. Moreover, a dropdown drawer coupled below the display surface of the furniture affords a worksurface for the electrical device when the present invention is in the workstation mode.
