A gas cylinder quick release device has a cylindrical upper assembly, a cylindrical lower assembly arranged below the upper assembly on a common axis, and a handle which is mounted to move between a first position and a second position. Movement of the handle from the first position to the second position imparts axial displacement of the upper and lower assemblies away from each other along the axis, thereby breaking a press-fit engagement of a wheelbase otherwise secured on the gas cylinder.

A stabilizing arrangement (1) to support an object above four ground engaging means (2c,3c,4c,5c) has first 2, second 3, third 4 and fourth 5 levers each having a beam portion (2a,3a,4a,5a), an actuating portion (2b,3b,4b,5b) and a ground engaging means (2c,3c,4c,5c). Each lever is connected to a common interconnection means (6) by a respective pivot with a pivot axis. The levers engage consecutively first to second, second to third, third to fourth and fourth to first, via respective projections (2d,3d,4d,5d) permitting ground engaging means warp displacement and thereby the arrangement provides support of the object on uneven ground. For each lever part, the distance a between the respective ground engaging means and the respective pivot axis is a primary lever-rotating moment arm, and the distance b between the respective ground engaging means and the centre of the pivot is a friction loading distance. The friction loading distance b can be greater than or equal to the primary lever-rotating moment arm a.

A fastening mechanism configured to connect a first member to a second member may have a clamp member having an enclosure for enclosing the first member. The mechanism may also have engagement sheets extending from two side edges of the enclosure. Each engagement sheet may have a first engagement portion. The mechanism may also have a locking member having slots where the engagement sheets of the clamp member may be configured to be inserted through the slots. The mechanism may also have an actuating and tensioning device having a main body portion provided with second engagement portions engaged with the first engagement portions, and a force application mechanism affixed to the main body portion for applying a force on the locking member to shift the relative position between the locking member and the clamp member. A furniture assembly using the fastening mechanism is also provided.

Disclosed is an assembly-friendly table frame, which relates to the field of lift tables. The table frame includes an upright and a base stand mounted to the underside of the upright; one of the base stand or the upright is securely coupled with a connecting member, and the other thereof is provided with a locking bump; the connecting member includes an insert-fitting rail and a locking slot provided in the insert-fitting rail; the locking bump is sequentially inserted into the insert rail and slid to be snapped into the locking slot; the table frame further includes an ejector member configured to eject the locking bump out of the locking slot. Further disclosed is a table applying the table frame. An advantage of the present disclosure lies in enhancing convenience of assembly and disassembly between the upright and the base stand.

The invention relates to a knock down table suitable for food preparation that includes extension legs and terminal legs that are interconnected with a threaded connector and threaded receiving plugs in the connecting ends of the extension and terminal legs. One of the receiving plugs in each connection protrudes from the end of its legs and is configured to extend into the connecting leg and abut with the receiving plug in the other leg.

A joint assembly includes a structural body having a key which projects cantilevered from an abutment surface. The key includes a stem with a first stem portion having a reduced transverse encumbrance, and a second stem portion from which fins project and define locking surfaces. A seat body includes an abutment counter-surface facing the abutment surface. A seat is formed by opening from the abutment counter-surface, which delimits a key entry slot. A first seat portion proximate the entry slot allows insertion of the key if the fins are aligned with the entry slot. A second seat portion internal and opposite the entry slot widens to allow free rotation of the key. The seat body forms locking counter-surfaces having an inclined plane portion moving away from the entry slot so that key rotation brings the abutment surface in force-contact against the abutment counter-surface, creating a firm frictional fit.

A foldable leg frame arrangement of a foldable table includes two runners extended along two longitudinal sides of a tabletop, a leg frame including a leg folding member, and a reinforcement unit. Each runner has a fastening hole formed at an inner side thereof. The leg folding member has two end portions rotatably inserted into the fastening holes of the runners respectively. The reinforcement unit includes two reinforcing shafts transversely extended from the runners respectively, wherein when the end portions of said leg folding member are rotatably inserted into the fastening holes of the runners respectively, the reinforcing shafts are inserted into the end portions of the leg folding member respectively. Therefor, the reinforcement unit not only forms a double lock configuration to securely mount the leg frame between the runners but also guides the leg frame to be rotated between a folded position and an unfolded position.

A system of modular components to assemble a desired article of furniture provides a plurality of tool-less fasteners and a collection of a plurality of furniture components selectively connectable to each other with one or more of the plurality of tool-less fasteners to assemble a desired article of furniture.

A table system includes a table surface and legs. The table surface includes a top planar surface and a bottom planar surface. The table surface also includes side surfaces having various curved or linear shapes. The shortest side surface has a substantially linear shape while the other side surfaces are curvilinear. The curved side surfaces each have a radius of curvature substantially the same. The table system also includes connection bars located beneath the table surface that also have substantially the same curved or linear shape as the side surfaces.

An improved support leg attachment assembly is provided. The support leg attachment assembly enables an easy transition of a portable structure, having a leg portion and a supported portion, between a detached storage configuration and an attached operative configuration, stably supporting the supported portion on the leg portion. The support leg attachment assembly provides two tenons on a proximal end the leg portion, and two mortises recessed along the supported portion, the two tenons and mortises dimensioned and adapted to snugly nest only upon an application of an engagement angle. Each of the two tenons and mortises providing contrasting materials for facilitating a long-lasting, effective support leg attachment assembly.
