A sofa bed with a seat back assembly, seat, side frame assembly and lock and release member. The side frame assembly includes a side frame and a link assembly connected to the side frame. The link assembly moves between a first position and a second position to allow for conversion of the sofa bed between a sofa position and a bed position. The lock and release mechanism locks the link assembly in place.

A motorized bed frame includes a support assembly having a torso section and a leg section. An adjustable assembly having a torso section and a leg section is positioned on the support assembly and pivotally coupled thereto. An actuating assembly is coupled to the support assembly and the adjustable assembly for articulating the torso section and leg section of the adjustable assembly relative to the support assembly when the bed frame is in an open configuration. Multiple bed frames could be coupled together side-by-side for larger mattress supports, and adjacent torso sections and leg sections of the adjustable assembly could be controlled simultaneously. The bed frame is foldable to a compact configuration without disassembly of parts.

A modular sofa assembly described herein includes a plurality of seating modules each having a seat section, a backrest section, and side edge surfaces. The backrest section includes first and second portions coupled for movement between a folded configuration and an extended configuration. An armrest module has an armrest side edge surface configured for mating engagement with a side edge surface of a seating module. The modular sofa is assembled by aligning connectors of the seating modules and armrest module, with each respective connectors slidingly engaged along an axis. After bringing the modules together, these connections are secured with the side edge surfaces in abutting engagement. The modular sofa further may include a power cradle mounted at the sofa's bottom surface. The power cradle includes a cubic power outlet near the front of the sofa, and power cable extending beyond the back of the sofa.

Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.

The present invention relates to a deployment system for a deployable sofa. The deployment system includes a deployment apparatus, and the deployment apparatus includes a bottom fixing member, a support, a swinging rod, a first multi-link rod mechanism, and a second multi-link rod mechanism, where the bottom fixing member is used to be fixedly mounted to a sofa bottom frame; the support is used to support a sofa seat; the swinging rod is rotatably connected to the support by means of the first multi-link rod mechanism, and the swinging rod is rotatably connected to the bottom fixing member by means of the second multi-link rod mechanism; the second multi-link rod mechanism is constructed to be capable of enabling the swinging rod to move approximately parallel to the bottom fixing member; and the first multi-link rod mechanism is constructed to be capable of transferring translation of the swinging rod to the support, to enable the support to move approximately parallel to the bottom fixing member. The present invention eliminates a jitter phenomenon during deployment of a deployable sofa, and a link rod mechanism is used to improve synchronicity and reduce manufacturing difficulty and maintenance fees.
