A quick-release device (210) is for securing a rod (13) of any gas cylinder (12) into the plate (11) of any chair, item of furniture, or other device supported by a gas cylinder and activating the rod with a button thereon. This universal quick-release device (210) includes a sleeve (230) in in the seat plate (11), an adapter (211) fit into the sleeve (230), the adapter (211) including an upper portion (237) and a lower portion (239) with different inner and outer diameters (235, 236). The sleeve (230) is configured to receive the lower portion (239) of the adapter (211) in a press-fit engagement. The upper portion (237) is configured to receive the rod (13) of the gas cylinder (12) in a removable engagement.

A quick-release device (10) for securing a gas cylinder (12) in a seat plate (11) includes a pedestal (30) defining a socket (33) for receiving the gas cylinder (12). The pedestal (30) projects upwardly from an endwall (75) to form a jaw against which the gas cylinder is received when applied to the socket. A clamp (31) is pivoted to the jaw (42) for movement between an open position and a closed position. A flange (70) is formed in the pedestal (30) and has a lower surface (71) for confrontation with the seat plate (11). A latch (32) is coupled to the pedestal. The latch (32) moves between a first position enabling movement of the clamp (31) between the open and closed positions, and a second position disabling movement of the clamp (31) between the open and closed positions.

A footrest device for supporting feet apart from a cylinder includes a central hub, an outer ring spaced apart from the central hub, and spars, each extending radially from a proximal end, on the first jaw of the hub, to a distal end on the ring. The hub is a clamp with an open condition and a closed condition for clamping onto the cylinder, and it includes first and second jaws pivoted to each other to open and close the hub about a space configured to receive the cylinder. A latch assembly opens and closes the first and second jaws with respect to each other.
A gas cylinder quick release device has an upper bearing plate, and a lower annular collar arranged below the upper bearing plate on an axis common to the upper bearing plate and the lower annular collar. A handle 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 bearing plate and the lower annular collar away from each other along the axis. The lower annular collar moves downward along the axis when the lower annular collar is axially displaced away from the upper bearing plate.

A gas cylinder quick release device (11) has a cylindrical upper assembly (20), a cylindrical lower assembly (21) arranged below the upper assembly (2) on a common axis (X), and a handle (23) which is mounted to move between a first position and a second position. Movement of the handle (23) from the first position to the second position imparts axial displacement of the upper and lower assemblies (20, 21) away from each other along the axis (X), thereby breaking a press-fit engagement of a wheelbase (13) otherwise secured on the gas cylinder (10).
