A quick lock-release mechanism for assembling a table plate to table legs that includes a lower ring, a cap, two locking wings and a two springs. The lower ring includes a central hole and two opening pins. The cap includes a circumferential rim and two pins. The locking wings include an axial hole, a hole for receiving a tension screw and a sloping side. The springs and the locking wings are designed to be assembled onto the spring wings pins. The tension screws are designed to be screwed into the holes for receiving the tension screw. The springs push the locking wings toward the center of the mechanism so that the locking wings cover a part of the central hole and when rotating the cap relatively to the lower ring the spring wings pins exert force on the locking wings and push back the locking wings.

A plurality of extremely flexible, functional, convertible and potentially compact tables having various optional features are disclosed. The tables comprise 4 or more folding table top panels, two or more joining pieces, four or more fixed legs and four or more swing out supporting legs and can be used in any of several configurations to serve from one to more than a dozen people. In its most compact configuration it is useful as a hall or wall table taking up very little space making it especially useful for apartments, condos, small homes, schools, churches and offices. Its extremely compact configuration makes it less costly to inventory and ship for the manufacturer, wholesaler, and retailer, and to store and/or use by the consumer.

An article of furniture may include a component such as a frame, leg, or support. The component may be constructed from a strip of material and the strip of material may include a strip length, a strip width, and a strip thickness. The component may include a longitudinal welding joint that may be disposed between a first strip end or a first strip side and a second strip end or second strip side. A profile may be embossed into a surface of the strip of material and the component may be manufactured in a continuous inline roll forming process.

A supporter for a woodworking table contains: four supporting rods, four driving columns, and two movable adjustment posts. Two middle sections of two of the four driving columns are rotatably connected with two middle sections of the other two of the four driving columns respectively, and one side of each of the four supporting rods is in connection with each of two ends of each driving column. The two movable adjustment posts parallelly correspond to each other, and each end of each of the two movable adjustment posts is rotatably connected with a middle section of each supporting rod. Each movable adjustment post includes an outer tube, an inner tube, and an adjustable stem. Thereby, the supporter of the present invention is collapsible so as to decrease its storage size. The supporter adjustably supports the table board based on a size of the table board.

In a table having a height-adjustable table top and supporting structures, the table top is secured on the supporting structures so that the supporting structures support the table top. The supporting structures are placeable on a floor. The table includes at least one band which connects the supporting structures and the table top to each other, so that the table top is supported by the supporting structures in that it hangs at the supporting structures with the aid of the band. The table permits a simple, convenient, quick and precise adjustment of the height of the table top according to the needs of the respective user of the table.

A collapsible platform system is provided for converting an underlying support surface to a standing desk. The collapsible platform system converts the underlying support surface to a standing desk with a large work surface suitable for performing a variety of tasks, including handwriting-type and/or sketching-type tasks. A collapsible platform of the system includes a work panel with an upper surface that defines a work surface. The work surface may support a deskwork article being used at the standing desk. A support arrangement can collapse with respect to the work panel to change the collapsible platform from an assembled state an unassembled or collapsed state. The support arrangement has multiple panels, at least one of which is segmented. A connection joint is defined between the segments of the segmented panel(s) for facilitating assembling and disassembling of the collapsible platform while changing the collapsible platform between the assembled and collapsed states.

A height-adjustable table includes a table top with two support block units, a linkage mechanism including first and second linkages respectively pivotally connected to the support block units, and a lifting control mechanism including first and second sliding tooth racks respectively slidably mounted in respective sliding open chambers of the support block units and respectively pivotally connected to first and second legs of the first and second linkages, two lock mechanisms with center gears thereof meshed with the first and second sliding tooth racks and two operating handles operable to lock/unlock the center gears for allowing the first and second linkages to be extended out or received so as to further adjust the elevation of the table top.

A tension-compression base structure including tension elements (such as flexible cables or ropes) and compression elements (such as rigid legs) is provided with a slidably adjustable path for the tension elements around or within the compression elements, thereby enabling a degree of adaptability to support surfaces that may not be ideally flat, such as on outdoor terrain. Such a tension-compression base may be used to support a platform, a stool, or an item of equipment that may be desirably held in a preferred orientation irrespective of terrain irregularities, and as furniture may be configured to rock with a user's body as a form of active seating.

A foldable table includes a table top and two leg units. Each leg unit is movable relative to the table top during folding and unfolding of the foldable table.

A foldable table having a deployment condition and a folded condition. The table includes a tabletop consisting of three equal-sized sectors, where the first and second sectors, the second and third sectors are rotatably joined together along adjacent side edges. In one example, the tabletop has a groove along the periphery of the sectors and a leg support for each of the sectors, where each leg support includes an outer leg component having an upper arcuate portion dimensioned and shaped to be accommodated at least partially into the groove when the table is in the folded condition. In another example, each leg support includes a depressed area configured to accommodate a portion of a respective sector and engage a side edge of the sector when the table is in the folded condition.
