  • Patent number: 9609955
    Abstract: A bed assembly and method of use for connecting a foldable bed frame to the back support of a sofa. The assembly includes a first slotted link attached to the back support and a double slotted link affixed to the foldable bed frame. An L-shaped adjustment link defining a plurality of apertures is slidably connected to the slotted link and pivotably connected to the double slotted link whereby folding the bed frame causes the back support to displace along the first slotted link. Depending on whether the foldable bed frame is being removed from or inserted into the storage cavity within the sofa, the displacement of the back support along the slotted link causes the space between the bed frame and the back support to change.

  • Publication number: 20140352056
    Abstract: A convertible seating unit is adaptable for use in different applications (e.g., motor home, travel trailer, hospital room, commercial, and residential). A frame and linking mechanism reduces the number of steps required to position the unit between seat and bed configurations. The mechanism includes seat and mid seat sections that are attached via a set of articulating linkage which provide that when the seat front is lifted and pulled up/outward, support feet automatically extend without secondary motion by the user. Once the support feet are supported by the floor, a back section is rotated forward from its seat to its bed position, thus completing conversion from a chair to a bed.

  • Publication number: 20110214231
    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 co-planar and generally horizontal. This provides a firm bed surface upon which a person may comfortably sleep. 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.

  • Patent number: 5855030
    Abstract: A folding sofa bed frame structure has a TV control link and an associated toothed ratchet element connected thereto, by which the rear end section of the structure can be selectively positioned in two differing "TV" positions. A cam portion on the ratchet element automatically effects disengagement from either TV position upon pivoting of the rear end section into a substantially perpendicular relation to the main intermediate section of the structure. The ratchet arrangement is effective to automatically engage into and disengage from either TV position without manual manipulation, other than manual lifting of the rear end section, and is automatically effective to disengage when the bed frame structure is folded into the sofa frame.
