摘要:
Collapsible articles of furniture are provided which have at least one leg assembly which includes a first leg and a second leg. The first leg has a first upper leg segment and a first lower leg segment coupled to the upper leg segment by a first link and the second leg has a movable second upper leg segment and a fixed second lower leg segment coupled to the upper leg segment by a second link. The two links are pivotally connected to each other for movement between an open position wherein the first and second legs cross each other to form a generally X- shaped configuration and a closed position wherein the upper and lower leg segments are aligned with each other and the upper leg section of the first leg is received within the lower leg section of the second leg and is aligned with and telescopically received within the lower leg section of the first leg. The pair of control links pivotally supported in a space between the link plates move in response to movement of the plates prevent telescopic connection between the upper and lower leg segments and prevent the upper leg segments from being telescopically received within the lower leg segments until a predetermined condition of alignment between the upper and lower leg segments has been attained.

A volume-adjustable unit comprising a first layer, a second layer, and multiple inner layers subsequently disposed between the first and second layers, each inner layer has two opposing sides, and each of the two opposing sides is adhered to an adjacent layer of the inner layers through an adhesive layer, the adhesive layer comprises multiple adhesive strips, the multiple adhesive strips are formed subsequently and substantially in parallel spaced apart from each other and are arranged in such a way that each section of the each inner layer adheres to at most one adjacent layer on one of the two opposing sides through an adhesive strip, whereby multiple hexagonal columns are formed by the inner layers as the unit is stretched-out. The unit can be used to prepare a volume-adjustable frame of a piece of furniture that is relatively light and can be transported from one place to another without taking up a lot of space.

L'invention concerne un siège pliant du type comprenant un dossier (20) et une assise (9) souples, e: au moins un croisillon (32). Le siège comporte des barres assise (7,8) qui portent l'assise (9) et des barres d'accoudoir (10, 11) qui forment deux ensembles mobiles dans le sens ascendant ou descendant lors du pliage ou dépliage; ces ensembles sont agencés d p façon à pouvoir coulisser le long des montants (1, 2). Le ou les croisillons sont avantageusement soudés, d'une part, sur des barres de piètement inférieures (5), d'autre part, sur des barres supplémentaires (31) en vue de donner une bonne rigidité d'ensemble au siège; ces barres de piètement et barres supplémentaires sont montées pivotantes autour de leur axe pour permettre le repliage du siège

A collapsible chair (10) has a backrest portion (26), a seat portion (28), first and second front cross members (16), first and second rear cross members (18), left and right armrest members (22), and left and right pairs of legs (12,14). Each of the first and second front cross members (16) and each of the first and second rear cross members (18) extends from the left pair of legs to the right pair of legs. The chair (10) is collapsed by folding the backrest portion (26) forward, moving the left pair of legs (12,14) toward the right pair of legs (12,14), and inverting the left and right armrest members (22) in a manner such that the backrest portion (26) wraps over the seat portion (28).

A collapsible and portable rocking chair includes left and right frame side assemblies collectively defining forward and rear leg portions, armrests, and back support members. The chair also includes cross-members connecting the left and right frame said assemblies and collectively defining a seat support in the set-up condition of the chair. The cross members are pivotally connected to one another as well as to the left and right frame side assemblies to facilitate folding of the chair frame to a collapsed condition. Each frame side assembly is supported on a fulcrum point for rocking movement of the chair frame. A rocker mechanism is attached to the chair frame to support the chair during rocking movement and to facilitate rocking of the chair in connection with the user's shifting weight. The rocker mechanism may be provided in connection with a front leg member, a rear leg member, or both.

The invention concerns a dismountable folding chair or armchair structure and, in particular, a "director"-type chair, in which a fold-up seat (1), defined by pivoted elements (7) crossing one another, is hinged to side frames (2) defining the supporting legs (3), the armrests (4) and backrest elements (5) of the chair. The folding seat (1) and the side frames (2) comprise reciprocal connecting means (18,20) which may snap on and off, to stiffen and hold the chair folded down. The seat and backrest fabrics (11, 6) moreover, are removably fitted in order to allow the fabrics themselves to be changed.

The extensible meshed bi-structure comprises: • a first meshed structure (SM-i), the meshes being distributed along a first plane, the first meshed structure (SM 1 ) being foldable along a first direction (D 1 ) comprised in the first plane (P 1 ); • a frame structure (SC) comprising at least two longitudinal elements rigidly connected to the first meshed structure (SM 1 ) and arranged on either side of the opposing edges of said first meshed structure (SM 1 ) and making it possible to vary the dimensions of the bi-structure; • a second meshed structure (SM 2) , the meshes being distributed along a second plane (P 2 ) parallel to the first plane, the second meshed structure (SM 2 ) being foldable along the first direction (D 1 ); • connection means (ML) between the first meshed structure (SM 1 ) and the second meshed structure (SM 2 ) so as to rigidly connect the two meshed structures to one another, the connecting means enabling synchronization of the folding of the two meshed structures (SM 1 , SM 2 ) in the first direction (D 1 ), the first and second meshed structures being woven in such a way that each mesh of each of the meshed structures is stitched to the neighbouring meshes thereof.
