  • Patent number: 7845290
    Abstract: Folding table having fixed support structure, a table-top articulated to the fixed support structure and movable between a lowered position and a raised position, and a first and a second pair of legs borne by the fixed support structure and movable between a usage position and a stowage position. The first and the second pair of legs are rotatable around respective vertical axes and are connected to the table-top by means of an actuating device which actuates the rotation of the first and of the second pair of legs as a result of the movement of the table-top from the lowered position to the raised position and vice versa.

  • Publication number: 20100109403
    Abstract: A chair comprising, a base structure including two rear tubular elements open at the top, a backrest having two tubular portions open at the bottom and aligned to said tubular elements of the base structure, and two elastic devices, each of which has a top support inserted in a tubular portion of the backrest, a bottom support inserted in the corresponding tubular element of the base structure, and an elastic element flexurally deformable to enable tilting between the top support and the bottom support, wherein each of said elastic devices comprises a plurality of sectors stacked on top of one another and arranged between the top support and the bottom support, and wherein, in a resting position of the elastic element, a plurality of slits are formed on the rear side of each elastic device between each pair of adjacent sectors.

  • Patent number: 7686395
    Abstract: A chair comprising a supporting structure having a seat and a backrest, in which the backrest comprises a deformable resting portion made of plastic material which has a non-planar resting surface provided with at least one weakened area which enables an elastic deformation of the resting portion so that the resting portion assumes a configuration bent backwards under the action of a thrust applied backwards by the user, two uprights formed integrally on the lateral sides of the resting portion, and two side connection elements, which connect the backrest to the supporting structure, formed integrally at the bottom ends of the uprights. The backrest is provided with elastic stiffening elements made of a material different from the material constituting the resting portion and arranged only in an area corresponding to the uprights so as to bestow upon said uprights a rigidity to bending higher than that of the resting portion.

  • Patent number: 7681952
    Abstract: A chair having a base adapted to support the chair on a support surface, and a seat and backrest mounted on the base that includes a flexible backrest and a relatively simple tilt mechanism for tilting the backrest relative to the seat. The tilt mechanism includes a pair of dual cantilevered U-shaped springs mounted on opposite sides of the base and in communication with the backrest. The backrest is mounted to the tilt mechanism such that a rearward thrust applied by the user deflects an outer end of each U-shaped spring downwardly to enable rearward tilting of the backrest relative to the seat. Upon removal of the rearward thrust, the backrest elastically returns to its initial position under the biasing force of the U-shaped springs.

  • Patent number: 7625044
    Abstract: Chair backrest, comprising a support structure constituted by a single piece of injected plastic material, including a bearing section having a front surface against which a user's back is to bear. The bearing section has an opening that extends in a lumbar region of the front surface. The backrest comprises a lumbar support panel movably positioned in said opening. The lumbar support panel has a front surface against which a lumbar region of the user's back is to bear and it has an outer perimeter that is connected to the edge of said opening by means of an elastic element that tends to thrust the support panel towards a position in which the front surface of the lumbar support panel projects anteriorly relative to the front surface of said bearing section.

  • Patent number: 7614351
    Abstract: A folding table includes a base structure (12) and a resting surface (14) mounted upon the base structure (14). The resting surface oscillates between a substantially vertical inoperative position, and a substantially horizontal operative position. The resting surface (14) is mounted so that it can oscillate with respect to the base structure (12) about a first horizontal axis (26). The base structure (12) includes a retention device (38), which has at least one articulation arm (40) articulated to the base structure (12) about a second horizontal axis (30) parallel to the first axis (26), and a connection member (42, 142) operatively set between said arm (40) and the resting surface (14).

  • Patent number: 7370910
    Abstract: A chair comprising a base structure (12) bearing a seat (14), a backrest (16) and a writing tablet (38) movable between a first lowered inoperative position and a raised operative position, in which in the first lowered inoperative position the tablet (38) is parallel to a vertical axis and is inclined relative to a vertical plane parallel to the longitudinal axis of the chair, so that two or more chairs of the same type can be approached longitudinally to each other with the tablets of two adjacent chairs partially superposed on each other. The writing tablet (38) is also provided with a second lowered inoperative position in which the tablet is inclined relative to a vertical axis and is inclined relative to said vertical plane parallel to the longitudinal axis of the chair, so that two or more chairs of the same type can also be superposed vertically on each other with the tablets of two adjacent chairs partially superposed on each other.

  • Publication number: 20080012412
    Abstract: Chair comprising a support base, a seat including a support structure that is movable relative to the support base between a lowered position and a raised position, and a backrest having a support structure articulated to the support base around a transverse axis and oscillating around said axis between a position of maximum forward inclination and a position of maximum backward inclination, in which the seat and the backrest are mutually connected in such a way that when the backrest is in the position of maximum forward inclination the seat is in the lowered position and when the backrest is in the position of maximum backward inclination the seat is in the raised position. The support structure of the seat is connected to the support base by means of at least one rocking lever articulated to the support base and to the support structure of the backrest around two mutually parallel transverse axes.
