Abstract: A foldable chair includes a first leg, a second leg pivotally connected with the first leg, and a seat module pivotally mounted on the first leg and detachably locked on the second leg. The second leg is formed with a forward protruding holding portion formed with a downward facing locking recess. The seat module includes a support frame pivotally connected with the first leg and formed with an upward protruding catch portion rested on the holding portion and detachably locked in the locking recess, so that the seat module is combined with the second leg. Thus, the expanded foldable chair has a rigid and stable structure.

Abstract: A portable chair has a front and rear seat support frames hingably joined for rotating the seat support frames between a first folded mutually aligned position for carrying the combination, and a second unfolded, spread apart position for sitting. The chair further includes a chair seat joining the pair of seat support frames and providing an upwardly facing surface when the seat support frames are in the second spread apart position. A back support frame is hingably joined to one of the pair of seat support frames and rotatable between an upwardly extending position for establishing a back rest, and a laid-over position wherein the back support frame abuts the chair seat. Attached to the back support frame is a backpack removably joined to the back support frame.

Abstract: Disclosed herein is a height-controllable childcare chair (1). This chair first comprises a pair of side walls (6) which are located on both sides of a seat portion (2). A pair of horizontally extending side bars (8), which are parallel to each other, are fixed to the respective side walls (6). A pair of first leg members (11) are rotatably mounted on the respective side walls (6). A pair of sliders (14) are mounted on the respective side bars (8) to be slidable along the side bars (8). A pair of second leg members (29) are rotatably mounted on the respective sliders (14). Respective intermediate portions of the second leg members (29) are rotatably coupled to respective intermediate portions of the first leg members (11). Wheels (13, 31) are mounted on respective lower end portions of the leg members (11, 29). A plurality of engaging holes (9a-9h) are longitudinally distributed along each side bar (8).

Abstract: This invention relates to a device for locking an adjusting finger in any one of the notches of a rack, wherein the first mobile element provided with the rack defines windows for the passage of retractable stops capable of being placed opposite the notches to stop the finger of the second mobile element, these stops being located at the free ends of flexible arms inclined in herringbone fashion and integral at their other ends with a sliding element provoking, when it is actuated, bending of said arms which abut on an edge of the windows and thus retraction of the stops.

Abstract: This invention relates to a multi-position, foldable armchair whose backrest inclination and seat height are adjustable, comprising, on each side, a crossed support of which the rear leg is articulated about a pivot pin under the front part of a seat and of which the front leg is connected to the rear part of the latter by a finger-rack arrangement. It also comprises a backrest articulated about a pivot pin on the front leg. Finally, it comprises an armrest articulated about a pin on the backrest and connected by a pin-rack arrangement to a compass element of which the front arm is articulated about a pin on the seat and of which the rear arm is articulated about the pin on the front leg. According to the invention, the rack of the seat is disengageable from the finger of the front leg and the rack of the armrest is releasable from the finger of the compass element, so that the armchair can be folded down flat.

Abstract: Folding piece of furniture, in particular folding stool, which comprises a seat face and leg pairs arranged laterally of the seat face. The seat face is provided with a means for mounting one of the two leg pairs and for guiding the other leg pair. These means permit an adjustment of the inclination of the seat face with respect to the second leg pair and also permit the collapsible piece of furniture to be folded up into an extremely compact form.

Abstract: A convertible chair involving a pair of X-frames, each providing a front and rear leg, and a seat pivotally secured directly at its front edge to the upper ends of the rear legs, and at its rear end to a pair of links, each in turn being pivotally secured to the upper end of one front leg, whereby the chair may be adjusted from a position for dining, in which the seat is substantially horizontal and the back substantially vertical, to a lower position with the seat and back tilted for lounging.
