In one example, a height adjustable desktop system is described that can include a work surface, a foot assembly and a linkage assembly that adjustably connects the work surface to the foot assembly allowing vertical adjustment of the work surface. The linkage assembly can include a pair of adjustment assemblies, each having a transverse linkage that maintains the work surface in a horizontal orientation as the work surface is elevated or lowered. A biasing mechanism, such as an extension spring or a torsion spring, biases the work surface toward the elevated position.

An expandable table comprises first and second table surfaces connected by a first hinge at their adjoining short sides. First and second legs are fixed to an underside of the first table surface to support the first table surface. A third leg is fixed to an end of a slidable bar or mechanism wherein the slidable bar or mechanism is installed on an underside of the first table surface, wherein the slidable bar or mechanism is configured to be slid out from under the first table surface wherein the third leg provides support for the second table surface when the second table surface is unfolded and wherein the slidable bar or mechanism is configured to be slid under the first table surface wherein the third leg rests adjacent to the first leg when the second table surface is folded to lie on top of the first table surface.

A tray attachment assembly providing a horizontal surface for placement of items thereon. The assembly includes a tray that defines the horizontal surface and a connection mechanism for fixedly clamping the tray to an attachment surface. The tray includes a first planar section extending between a first lateral edge and a second lateral edge that defines the horizontal surface. A second planar section extends from the second lateral edge of the first planar section at a transverse angle from the first planar section for preventing unintended interaction with the connection mechanism. The transition between the first planar section and the second planar section presents a rounded profile.

The present invention relates to a refrigeration-heating cycle expandable heat preservation table with an intelligent air filtration function, comprising a support frame, a refrigeration mechanism, an expandable heat preservation table top and an air filtration mechanism; the refrigeration mechanism comprising a heat preservation box, a storage box, a first air pump and a heat spreader; the expandable heat preservation table top provided thereon with a heat equalizing plate and a control panel; the air filtration mechanism comprising a second air pump, a solid filter tank, a liquid filter tank, a controller and a battery; the solid filter tank provided therein with an air quality sensor group, an intake pipe and activated carbon; the liquid filter tank provided therein with a float switch, an electronically controlled hydraulic check valve, an outlet pipe and a tilt sensor. The present invention is a refrigeration-heating cycle expandable heat preservation table with an intelligent air filtration function, which has a reasonable structure and the advantages of simple structure, convenient use, high level of intelligence, and good heat preservation effect, effectively solving the problem of existing heat preservation tables having only a single function.

A cabinet which includes a tray formed into a rectangular flat plate shape slidable between a storage position and a drawing position under the top board and above one or a plurality of drawers, space formed between the top board and the tray, and a first extension board and a second extension board turnably attached respectively to both sides of the top board. The first extension board and the second extension board are turnable between a closed position where the first and second extension boards overlap a top surface of the top board and an open position where the first and second extension boards are opened sideways respectively from left and right sides of the top board. The top surface of the top board and top surfaces of the first extension board and the second extension board are arranged on a same plane.
