  • Patent number: 11812855
    Abstract: A folding bed, such as a sofa bed, with an assembly configured to counteract the gravitational forces acting on both a rotation of the main panel in relation to the frame and a rotation of the foot panel in relation to the main panel. A transmission may be used in the assembly to connect the first pivotal connection, where the main panel pivots with respect to the frame, to the second pivotal connection, where the foot panel pivots with respect to the main panel. The transmission transmits torque from the first pivotal connection to the second pivotal connection, so as to counteract gravitational forces acting on the foot edge of the foot panel.

  • Patent number: 8997273
    Abstract: A seating unit that includes a foldable bed includes: a base with an internal cavity; a foldable bed that includes a plurality of sections, wherein in a folded position, the bed sections are folded relative to each other and stored within the base cavity, and in an unfolded position, the bed sections are generally horizontally disposed and in serial alignment with each other, with a first bed section being positioned forwardly of the base; a bed folding mechanism that is attached to the base and the bed sections that controls the movement of the bed between the folded and unfolded positions; a foldable leg attached to the first bed section, and a leg folding mechanism attached to the leg and the first bed section configured to extend the leg downwardly from the first bed section when the bed is in the unfolded position, and to fold the leg under the first bed section when the bed is in the folded position, the leg being pivotable about an axis that is parallel with the forward direction.

  • Patent number: 8881325
    Abstract: A convertible sofa-bed which is easy to convert between a sofa configuration and a bed configuration is provided. From a sofa configuration, a buttock-foot member may be pulled outward. Simultaneously, a head rest member and back rest member which are initially at a generally vertical position are traversed to a generally horizontal position. When the buttock-foot member is fully traversed outward (i.e., extended position), the head rest member, back rest member and the buttock-foot member are generally substantially coplanar and generally horizontal. This provides a firm bed. From the bed configuration, head rest member and the back rest member may be buckled to allow the buttock-foot member to be pushed inward. The buttock-foot member is then pushed fully inward (i.e., retracted position) until the head rest member and the back rest member are in the generally vertical position with the buttock-foot member and back rest member forming a seat.

  • Patent number: 5257424
    Abstract: A foldable bed comprising a frame including a body section, a cavity section, a seat section, and a foot section, each of which includes a pair of side rails, each of which are pivotally interconnected and which are movable between an unfolded position and a folded position, a mattress carried by the frame and movable therewith between the unfolded and folded positions, wherein in the folded position the mattress is folded upon itself to define an upper support surface, and interconnecting means for pivoting the frame sections between the unfolded position and the folded position, wherein in the unfolded position the body section, the cavity section, the seat section, and the foot section are serially and horizontally aligned, and the side rails of the sections are positioned along respective opposite sides of and generally below the mattress, and in the folded position, the body section is generally horizontal, the seat section overlies the body section, the cavity section extends substantially vertically be

  • Patent number: 4999865
    Abstract: A foldable bed assembly is disclosed. A foldable bed frame having a series of foldable sections is positioned within a cabinet for storage and is moved through a wall opening to a horizontal operating position. Links connect the bed frame to the cabinet. Elastic bands slow the movement of respective pairs of foldable sections when moved between the stored position and the operating position.

  • Patent number: 4619005
    Abstract: A combined waterbed, sofa and sofa table includes a waterbed frame, a sofa mounted on the frame and covering a portion of the waterbed, and a foldable table secured over another portion of the waterbed adjacent the back support of the sofa. The sofa can be removed from the waterbed frame and the table pivoted away from the waterbed to provide full access thereto. In another configuration, the sofa can be removed and reversed on the frame so that the seat of the sofa faces the table, with the waterbed providing a soft underfooting for persons seated on the sofa at the table. Accordingly, waterbed, sofa and table functions are provided, together or separately, in a single furniture unit.

  • Patent number: 4592102
    Abstract: A rectangular mattress support frame has side rails formed of rail sections which are pivotally interconnected for movement between a folded seating position and an unfolded sleeping position. In the sleeping position, side rail portions projecting forwardly of the furniture frame are supported on a forward support leg and a center support leg. When a first rail section at the forward end of the side rail is pivoted upwardly, a linkage moves the forward support leg toward the first rail section, and this linkage also produces upward pivotal movement of a second rail section relative to a third rail section. The center leg is moved to a partially raised position in response to pivotal movement between the second and third rail sections, and it is moved to a fully raised position when a fourth rail section at the rear end of the side rail moves from a generally horizontal position to a generally vertical position.
