  • Patent number: 9301611
    Abstract: A leg and foot support structure applied to tiltable armchairs, comprised of a quadrangular rigid structure, said quadrangular rigid structure being lifted by means of feet; a pivotable quadrangular articulated frame for supporting the feet that is assembled on the front half and within said rigid structure; moving parts of said structure being operated by driving assemblies comprised of articulated arms connected and actuated simultaneously by a driving unit. An inner sliding frame composed of two quadrangular structures that slide over each other through articulated arms pivoted to the respective structures and to a rigid articulated frame that is angularly moved in order to be underneath a seat structure; said quadrangular structures start their relative slippage only after the articulated rigid frame reaches an end of its angular displacement.

  • Patent number: 5782535
    Abstract: An armchair, comprising: a base (10); a support frame (20), forming a framework to be fixed under the seat of an armchair portion (30); a footrest (40), comprising a first footrest portion articulated with the support frame (20), angularly displaceable between a non-operative position, inferiorly adjacent to the support frame (20), and an operative position projecting forwards from the armchair portion (30); and a second footrest portion (42, 420) mounted onto the first footrest portion (41), and linearly displaceable between a retracted position overlapped by the first footrest portion (41) and an extended position projecting therefrom; first impelling means (50), for promoting the angular displacement of the first footrest portion (41); and second impelling means (60, 600) promoting the linear displacement of the second footrest portion (42, 420) to and from its extended position in response to the respective angular displacement of the first footrest portion (41) to and from its operative position.

  • Patent number: 5000510
    Abstract: A reclining armchair having a seat articulated to a reclining chairback. The chairback is provided with a lower extension interlinked to a foot rest and articulated to the seat. An adjustable head support is assembled over the chairback. The seat (10) and the chairback (20) are articulated to the chassis (50) by pairs of lateral rods (11, 12). The lower end of the head support (40) is articulated to the chassis (50) and to the seat/chairback articulation point by erection rods (42) and erection arms (43) respectively. Movement of the armchair is controlled by a command lever (60) articulated to one lateral column of the chassis (50) and interlinked to the lower end of the chairback (20).

  • Patent number: 4939802
    Abstract: "SOFA-BED", comprising a basic structure (10) provided with a pair of upper rear supports (13); a back including a rear portion (20) and a front portion (30) articulated to each other, the rear portion (20) having its extreme lower edge articulated to the upper rear supports (13); a seat (40) having its rear edge articulated to the front extreme edge of the front portion of back (30) and having its front edge articulated to a footrest (50), seat (40) being supported on two pairs of rollers (41, 42) so as to be horizontally displaceable between a "sofa" and a "bed" condition, with the back portions and the footrest arranged horizontally and coplanar with seat (40). The rear portion of seat (20) may further assume different raised positions in respect of the horizontal, when the davenport is in the "bed" condition.

  • Patent number: 4141590
    Abstract: A collapsible furniture structure comprises a pair of free standing vertical support elements and a pair of rigid, U-shaped frame elements. Orifices are formed in the upper portions of the vertical support elements in which the extremities of the U-shaped frame elements are inserted and supported. The orifices are oriented and located so that, in the case of a chair, one of the frame elements extends forwardly from the support elements to define a seat portion of the chair while the other of the frame elements extends upwardly from the support elements to define a back rest portion of the chair. A cushion may be placed over the mounted frame elements for added comfort. Additional orifices may be formed in the lower portion of the vertical support elements into which additional floor engaging frame elements are inserted to provide a wider base to the structure. All frame elements are readily removable from the orifices to disassemble the structure for moving or storage.
