Provided is a portable folding chair, comprising a supporting frame and a cloth cover cushion, wherein the supporting frame comprises a fixed seat, supporting legs rotatably connected to the fixed seat, and a supporting assembly connected to the supporting legs, a plurality of limiting plates and lugs positioned at two sides of the limiting plates are provided on a periphery of the fixed seat, and an accommodating groove for mounting the supporting leg is formed between the limiting plate and the lug. According to the present utility model, the supporting legs are prevented from being unfolded at an excessive angle, it is effectively guaranteed that the supporting legs will not shake on the fixed seat when the portable folding chair is used by a user, and the portable folding chair is effectively prevented from falling due to shaking of the supporting legs when placed on uneven ground.

An assembly for a seat includes a pivot hub defining multiple rotation axes, and a displacing module attached to the pivot hub. Extendable legs are rotatably coupled to the pivot hub and comprise locking devices movable between an unlocked position, in which the legs, when extended, are enabled to retract, and a locked position, in which the legs, when extended, are prevented from retracting. The legs are rotatable between an intermediate position and a deployed position. When the legs are extended, and when in the intermediate position, the displacing module engages the locking devices to move the locking devices from the locked position to the unlocked position. When the legs are extended, rotating the legs from the intermediate position to the deployed position brings the displacing module out of contact with the locking devices.

The invention relates to a portable chair (1) having two front chair legs (2, 3), two rear chair legs (4, 5), two front chair arms (6, 7), two rear chair arms (8, 9), and two connection elements which are connected via a connection rod. The front chair legs and the rear chair legs each have a free end (2a, 3a, 4a, 5a) which is oriented towards an underlying surface (10), and the front chair arms and rear chair arms each have a free end (8c, 9c) which is oriented towards a seat surface (11) that is defined or can be defined by free ends (6a, 7a) of the front chair arms and free ends of the rear chair arms (8, 9).

The elevating lift with a stabilized movable base includes a base with extendable legs that provide minimum to maximum adjustable stability during use and transport. A lift system is mounted on the base, and a platform assembly is mounted on top of the lift system for selective raising or lowering. Each extendable leg supports a caster, rendering the base movable, and selective extension and retraction of the legs adjusts the stability of the lift. The plurality of legs can be further driven to simultaneously rotate about the vertical axis to steer the lift. The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple elevating lifts may be used to support linked platform assemblies in various configurations.

Embodiments of chair systems incorporating trekking poles include a low-back design employing fixed-length trekking poles, and a high-back design employing adjustable-length trekking poles that allow for adjusting the recline angle of the chair. The chair system generally includes a tubular frame that releasably engages a flexible seat. The tubular frame includes a front hub and a rear hub spaced one from the other by a cross bar, plus front and rear footings which stabilize the chair system on the ground or undersurface. A V-shaped upper support extending from the front hub supports and holds open the leg portion of the flexible seat, while the trekking poles are releasably engaged with and extend upwardly from the rear hub to support, and hold open and upright the back portion of the flexible seat.

The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple to elevating lifts may be used to support linked platform assemblies in various configurations.

To create a stable and safe frame, more particularly in the form of a tripod, having a plurality of rod-like legs (2), which are fastened centrally to a connection part (3), wherein the frame (1) can be folded up into a space-saving transportation position, in which the legs are oriented substantially in parallel, and the frame can be folded out into a usage position, in which the legs are crossed, the invention proposes that at least one concavely rounded support surface (5) for providing support over an area of the leg surface is arranged between the legs (2), more particularly that two support surfaces (5, 5) of this type are provided, which in the usage position are in contact with an area of the respective leg surface opposite one another.

A split folding furniture support device having an upper support portion and a lower support portion. The upper support section is connected and secured to the lower support section as the shaft inserts into the guide tube. The lower end of the upper main plate touches the upper end of lower main plate forming a load-bearing support. The device can be used to make folding tables, thin waist stool and rotary backrest chair with split, fold and rotation functions.

A folding seat support frame includes an upper support frame detachably connected to a seat fabric and a lower support frame connected to the upper support frame, where the upper support frame includes an upper connector, short rods rotationally connected to the upper connector at a first limited angle, and upper connecting rods rotationally connected to the short rods at a second limited angle; the lower support frame includes a lower connector and lower connecting rods rotationally connected to the lower connector at a third limited angle; the lower connector and the upper connector are coaxially and rotationally connected; when the folding seat support frame is in an unfolded state, the lower connecting rods and the short rods are oriented to a side of the lower connector; when the folding seat support frame is in a folded state, the short rods are butted against the lower connector.

This invention relates to a stand (FIG. 1) for a sitting or lying furniture, which stand is adjustable into a folded position for storage (FIG. 4) and transport and one or more extended usage positions. The stand has at least three legs (2), that in the usage position extend obliquely downward and outward and at least three arms (3), that in the usage position extends obliquely upward and outward and are arranged to support a canvas shaped sitting or lying module (FIG. 5-8). Arms and legs are at their lower and upper sections pivotally attached to a connecting hub (1a). A locking mechanism is attached to the connecting hub or the control means (4,8) and is arranged to restrict the legs movement outwards in the usage position. In the folded position the arms and legs extend substantially upward. The invention also refers to a sitting or lying furniture that includes such a stand.
