A support frame may be mounted to a corresponding support platform. The support frame may include an elongate rigid column including a proximal end and a distal end opposite the proximal end. A platen bracket may be connected to the elongate rigid column nearer the proximal end than the distal end. A support platen may be connected to the platen bracket. A flanged sleeve may be coaxially received on the elongate rigid column nearer the distal end than the proximal end. The flanged sleeve may include a sleeve portion slidably received on the elongate rigid column and a mounting flange extending from the sleeve portion. The mounting flange may be configured to interface with the support platform. A guide sleeve may be coaxially received on the elongate rigid column between the platen bracket and the flanged sleeve. The guide sleeve may be configured to maintain the platen bracket and the flanged sleeve in a spaced apart orientation when the support frame is mounted to the corresponding support platform.

The present invention relates to a tiltable chair including: a fixing base having a tiltable housing disposed on an upward protruding dome-shaped center thereof in such a manner as to be movable in an arbitrary direction; a gas cylinder disposed inside the tiltable housing in such a manner as to be linearly reciprocated in upward and downward directions; a seat plate disposed on top of the gas cylinder; and an elastic tiltable member disposed inside the fixing base in such a manner as to accommodate a longitudinal lower part of the gas cylinder therein to allow the gas cylinder to move tiltably about vertical axis to the bottom of the fixing base, wherein the elastic tiltable member includes a fixed frame located on the bottom of the fixing base, a coupling frame located inside the center portion of the fixed frame to accommodate the gas cylinder therein, and a rubber packing located between the fixed frame and the coupling frame and deformed elastically in every direction, wherein the rubber packing has tilt concave grooves formed inward to a given depth from top and underside respectively in such a manner that the tilt concave grooves are reduced in width toward the insides thereof to thus form inclined surfaces.

Accordingly, the tiltable chair is configured to have the elastic tiltable member for accommodating the gas cylinder therein, instead of a large number of coil springs complicated in structure in the conventional practice, so that the tiltable chair can be made simple in structure, thereby preventing the generation of noise when tilted.

A detachable swivel tin chair comprises a seat, chair leg and tray, the tray comprises an upper connecting tray, a lower connecting tray and a rotating device. The rotating device comprises a first connecting piece, a ball bearing and a second connecting piece. The first and second connecting piece rotate relative to each other through the ball bearing, the seat is fixedly connected to the upper end of the upper connecting tray. The chair legs include four supporting legs, the upper end of the legs are provided with an arc-shaped folded edge, which is provided with three first screw holes, the lower end of the lower connecting tray is provided with second screw holes. A long annular reinforcing rib is welded on the middle and lower sections of the supporting leg and connecting pieces are welded at the middle and lower sections on the inner side of the supporting feet.

A removable swim-up dock bar is described. The dock bar is removably attachable to a submerged foundation of an existing dock and may have adjustable seats or adjustable legs to ensure proper height and stability.

A tiltable chair includes a fixing base having a tiltable housing. A gas cylinder inside the tiltable housing reciprocates in upward and downward directions. A seat plate is on top of the gas cylinder. And an elastic tiltable member is inside the fixing base accommodates a longitudinal lower part of the gas cylinder so the gas cylinder moves tiltably about a vertical axis to the bottom of the fixing base. A fixed frame is on the bottom of the fixing base, a coupling frame is inside the center portion of the fixed frame to accommodate the gas cylinder therein, and a rubber packing is between the fixed frame and the coupling frame and deformed elastically in every direction. The rubber packing has tilt concave grooves formed inward to a given depth from top and underside reduced in width toward the insides thereof to form inclined surfaces.

A removable swim-up dock bar is described. The dock bar is removably attachable to a submerged foundation of an existing dock and may have adjustable seats or adjustable legs to ensure proper height and stability.

An adjustable stool having a support connected to a base at one end and seat at the opposite end. A foot rest is adjustably connected to the support. Adjustably connected to the seat is a back support. A lumbar support is adjustably connected to the back support. The back support has a horizontal portion and a vertical portion.

A seating arrangement to be used on a floor includes a support assembly and a seat assembly with a top surface. The support assembly includes a top plate, a bottom plate, a compressible elastic member between the top and bottom plates, and a fastener assembly connecting the top and bottom plates. A diameter of the compressible elastic member is greater than or equal to 40% of a diameter or a length of a diagonal of the top surface of the seat assembly. In response to offset weight placed on the seat assembly, the compressible elastic member selectively compresses causing the seat assembly to axially tilt in substantially any direction such that a plane of the seat assembly tilts downward from a neutral position substantially parallel to the floor, and decompress to the neutral position, in response to the offset weight removed from the seat assembly.

A multi-positional chair assembly comprises a frame portion defined by a pair of sinuously-shaped bars. The frame portion includes a back support section, a middle section, and a buttocks support section. A panel provides a supportive surface for a user. The panel may include a metal sheet, apertures, or parallel strips of material. The frame portion can be positioned in multiple positions to provide a sitting surface, including a lounge chair position and a higher elevated stool position. The chair assembly reconfigures between the lounge chair position and the stool position through rotation. Rotating the buttocks support section and the legs to engage the ground surface achieves the lounge chair position. And rotating the back support section and the legs to engage the ground surface achieves the stool position. The chair may be of a one-piece injection-molded construction.
