Abstract: An adjustable bed having a mattress support platform and a fixed frame base with wheels. A lift mechanism interconnects the mattress support platform and the fixed frame base to displace the mattress support platform between a fully collapsed position and a fully elevated position. The lift mechanism includes leg members pivotally connected with the fixed frame base and with the mattress support platform. A force multiplying actuating linkage interconnects an actuator and the fixed frame base. The actuating linkage includes a driving link and an intermediate link. The driving link has a first end pivotally mounted to the fixed frame base and a second end pivotally connected to the actuator. The intermediate link is pivotally connected to the driving link, and is pivotally engaged with one of the leg members and a stabilizing link. The stabilizing link interconnects one of the leg members and the fixed frame base.

Abstract: An adjustable bed is described that includes a main frame having a mattress support platform mounted thereon, wheels mounted to the main frame for displacement of the adjustable bed, and a lift mechanism supporting the main frame and actuable to displace same between a fully collapsed position and a fully elevated position. The lift mechanism includes two or more leg members each having a first end pivotally connected with a corresponding one of the wheels at a lower pivot and a second end pivotally connected with the main frame at a movable upper pivot. A stabilizer link has an upper end pivotally connected with the main frame and a lower end pivotally connected with each the leg member at an intermediate pivot point. An actuating assembly includes at least one actuator having a force multiplying actuating linkage interconnecting the actuator and the stabilizer link.

Abstract: An adjustable bed includes a main frame which supports a mattress platform, a fixed frame base having wheels mounted thereto for displacement thereof on a floor surface, and a lift mechanism interconnecting the main frame and the fixed frame base. The lift mechanism supports the main frame and is actuated to displace and position the main frame between a fully collapsed position and a fully elevated position relative to the fixed frame base without any longitudinal displacement of the bed. The main frame, the fixed base and the lift mechanism collapse into a low profile bed configuration in the fully collapsed position, such that the mattress platform is located at a minimum vertical height of at most 9 inches above the floor surface.
