A foldable chair has frames connected to one another by cross supports, bases connected to the frames by base supports and frame supports, with springs secured between the base supports and frame supports to allow for back and forth movement of the frames when a user is seated in the chair. The foldable chair includes a pliant membrane providing a seating surface for supporting the user.

A rocker chair having a frame and a longitudinal spring member extending from the frame, at or near a surface on which the chair is supported for rocking motion. The spring member includes an anchored portion anchored to the frame, and an extended portion extending from the anchored portion and is free to flex or bend against spring bias of the extended portion, wherein the extended portion is bendable upward from the support surface against spring bias of the extended portion. The frame of the rocker chair may be collapsible to convert from a collapsed configuration for stowing, to an extended configuration for seating a person. The spring member may include an anchored portion anchored to at least a portion of a bottom of the frame, and an extended portion extending from the anchored portion, wherein the extended portion is bendable against spring bias of the extended portion.

A foldable chair includes backrest rods hinged to a seat unit, leg units, armrest units, a first foldable rod unit, and a linking rod unit. Each leg unit includes a sleeve member connected to the seat unit and slidably sleeved on a rear leg rod connected to the seat unit. Each armrest unit is connected to one of the leg units and one of the backrest rods. The first foldable rod unit is connected between the backrest rods to move the backrest rods. The linking rod unit includes an end connected to the first foldable rod unit, and another end pivotally connected to one of the backrest arm units, or one of the sleeve members of the leg units.

A foldable rocking chair, including a foldable chair frame, a seat cushion cloth and two rocking bars, wherein the seat cushion cloth is detachably installed on the chair frame, and the two rocking bars are installed on left and right sides of the chair frame, respectively; each of the rocking bars includes an upper rocking bar, a torsional spring base, a lower rocking bar and a bottom tube, the upper rocking bar and the lower rocking bar are rotatably connected to both ends of the torsional spring base, and an upper end of the upper rocking bar is rotatably connected to a rear end on the left or right side of the chair frame; and each of the bottom tubes is placed on the ground and includes a front bottom tube and a rear bottom tube.

The utility model relates to a pneumatic brake release apparatus used on an elevator traction machine. By means of the technical solution, the air films in the air cabin are pushed by using compressed air to drive the push rod to transfer a thrust force, so that the locking arms are unfolded, and the locking brake and the brake release are implemented in a pneumatic way. Therefore, the problems in the prior art that a great amount of electric energy is consumed and the noise is difficult to eliminate can be solved, no noise is generated during operation, the safety is high, the structure is simple, and the manufacturing cost is greatly reduced.

A seat assembly for wheelchair of the type having a structure expandable from a contracted condition to an expanded position comprises a pair of tubular members connected to the structure. Each tubular member has a main tubular body, a secondary tubular body parallel to and inside the main tubular body, and an elongated slit extending along both the main tubular body and the secondary tubular body and common to both the main tubular body and the secondary tubular body. The slits open into an inner channel of the secondary tubular body. The main tubular body and the secondary tubular body form a hollow integral piece of composite material. A panel, e.g., of non-rigid material has rods on its opposite edges, the rods having a diameter smaller than that of the secondary tube and larger than a width of the slit to be held captive in the secondary tube, whereby the panel extends through the slit.

First and second U-shaped cross-members each have legs connected by cross bars and pivotally connected with each other at central portions thereof, and are mutually movable from a generally X-shaped setup condition in which the cross bars are transversely spaced apart, to a generally flat collapsed condition. Right and left frame side assemblies respectively are pivotally connected to the first and second cross-members at terminal ends of their respective front and rear portions and by at least one lost motion linkage.

Transportable folder-chair formed by two foldable/unfoldable parts, one of which is rectangular prismatic with two flat faces and two faces in the form of bellows, with extensions for forming the seat surface in an unfolded position, or position of use of the chair, which continue in flaps with two cutouts, and a set of flaps and fold lines, from which a folder is formed in the fold thereof. The transportable folder-chair also has a strap fixed by two ends for transporting the unit in the folded position thereof.

A double heated recreational chair includes a pair of chair frames and a table top tray pivotally and swivelly carried by the chair frame. The chair frame is selectively deployable in a folded, collapsed configuration in which the table top tray is deployed in a folded position adjacent to the chair frame. The chair frame is selectively deployable in an extended, functional configuration in which the table top tray is supported on the chair frame in a generally horizontal position.
