Abstract: A foldable bed comprises a bed surface unit, one or more first support legs, a first linkage bar, and a second linkage bar. A four-bar linkage is defined by the bed surface unit, the one or more first support legs, the first linkage bar, and the second linkage bar, and the four-bar linkage is configured to be changed to be alternatively in a folded state or a supporting state. A first triangular support structure is defined by the first linkage bar, the bed surface unit, and the one or more first support legs, and a second triangular support structure is defined by the second linkage bar, the bed surface unit, and the one or more first support legs.

Abstract: A foldable mattress support has an adjustable inner frame with a ratchet support for raising the head of a mattress. Legs are incorporated into the side and end bars of the mattress support. Upper and lower bars of the support are pivotally attached to the vertical plate of a hinge. Bolts oriented along axes of rotation pass through the bars and through the vertical plate. A first upper bar pivots about a first axis; a second upper bar pivots about a second axis; a first lower bar pivots about a third axis; and a second lower bar pivots about a fourth axis. Each of the axes is orthogonal to the vertical plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis. The distal ends of the upper and lower bars are pivotally attached to end bars.

Abstract: A hospital bed includes a base, a lifting mechanism, a rotating frame configured to rotate horizontally relative to the base, and a patient support surface pivotally secured to the rotating frame. The patient support surface includes a back section, a seat section, and foot section that articulate relative to each other. The patient support surface translates from a bed configuration to a side-egress chair configuration. The foot section includes a plurality of panels that translate relative to each other from a substantially co-planar relationship when the patient support surface is in a bed configuration to a relationship where one of the foot section panels is substantially orthogonal to another foot section panel when the patient support surface is in a chair configuration. A mattress supported by the patient support surface has a retractable foot portion that adjusts its length in response to translation of the foot section panels.

Abstract: A foldable mattress support is made by covering a metal frame with a fabric covering. The metal frame includes two sections that fold together at two hinges. A first section includes first upper and lower frames, and a second section includes second upper and lower frames. Each of the upper and lower frames is pivotally attached to a hinge. A bolt that is oriented along a first axis passes through the first upper frame and through a plate of the hinge. The first upper frame pivots about a first axis; the second upper frame pivots about a second axis; the first lower frame pivots about a third axis; and the second lower frame pivots about a fourth axis. Each of the axes is orthogonal to the plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis.

Abstract: A foldable bed frame including first coupling members each having an opening facing outwardly with respect to the frame being in an open state; two sets of longitudinal beams, each formed by two longitudinal bars having two free ends, and two inner ends pivotally connected within one of the openings of the first coupling members. At least two transverse beams, each being formed by two transverse bars having first and second ends, the first ends respectively being pivotally connected together by a second coupling member. A plurality of third coupling members provided proximate to each free end of the longitudinal bars, each third coupling member having an opening facing inwardly with respect to the frame being in the open state, the opening being configured to pivotally connect one of the free ends of the longitudinal bars. A leg pivotally connected respectively proximate the free end of each longitudinal bar.

Abstract: A collapsible headboard for providing a headboard for a mattress to inhibit pillows falling off of the mattress. The collapsible headboard includes a frame assembly being selectively actuated between a collapsed position and a deployed position. The frame assembly is designed for receiving the mattress when the frame assembly is in the deployed position. The frame assembly is actuated to the collapsed position for facilitating storage of the frame assembly when the frame assembly is removed from the mattress. A panel member is coupled to the frame assembly. The panel member is designed for being positioned against the mattress whereby the panel member is for inhibiting pillows from sliding off of the mattress when the frame assembly is in the deployed position.

Abstract: An articulation mechanism has a central part and a head part each made of a pair of shaped elements. The pairs of shaped elements form inner and outer shells. The inner shells are positioned inside the outer shells. The pairs of shaped elements are pivotable relative to one another and lockable relative to one another in several positions in one pivot direction. The outer shells have inwardly oriented projections and the inner shells have openings. A slide is moveably arranged inside the inner shells. The slide has locking members projecting through the openings of the inner shells and engaging intermediate spaces of the projections. A spring acts on the slide in an engagement direction of the locking members relative to the projections. The projections are shaped such that the locking members automatically reach a locking position in a first pivot direction of the head part.

Abstract: In a folding bed with a central dolly, the dolly comprises two separate parts that can be assembled together: a trestle made of a shaped tubular bar which forms two side shoulders and base sections, and two box members of plastic material that are mounted and snap fastened on the trestle shoulders and that are equipped at their ends with seats for the pivotal connection of side parts of the folding bed.

Abstract: A folding bed having a three section mainframe, a swinging left frame, a swinging right frame, these swinging frames hingedly attached on each end of a third stationary section at a mid portion of the mainframe. Foldaway legs are each hingedly connected near a longitudinal edge of the folding mainframe. These above features are in combination with a detachable middle support leg attaching to each third stationary section on the two longitudinal sides of the mainframe. A first structure element is attached to the head lateral side forming the head board, this structure element differing in design from a second structure element attached to the foot lateral side forming the foot board. The mattress support element on the mainframe is made up of independent rows of flexible metal structure running from one longitudinal side of the mainframe to its opposite corresponding longitudinal side.

Abstract: A foldable bed assembly includes a mattress, a mediate supporter, a front frame having a first end pivotally connected to the mediate supporter, and a rear frame having a first end pivotally connected to the mediate supporter. A head frame is securely attached to a second end of the front frame and includes a lower end securely located on the ground to avoid sliding. A rear leg frame is securely attached to a second end of the rear frame. One of the front frame and the rear frame includes two handles respectively attached to two lateral sides thereof. Each handle includes an extension that is located between the front frame and the rear frame when the foldable bed assembly is in a folded status.
