Abstract

Retractable beds exist and work on a myriad of mechanisms for enabling bed and mattresses to be retracted and deployed. However, structural deficiencies together with the weight of the mattress have contributed to deficiencies and damage to these retractable beds. An embodiment of the invention herein describes a positioning assembly comprising a platform structure supported by a support structure. The platform structure supports a mattress which is retractable towards the support structure. The positioning assembly further comprises a leg structure configured for being displaceable for supporting the platform structure in cooperation with the support structure when deployed. The leg structure further linked to the support structure for retraction thereof when the platform structure is retracted. The platform assembly further comprises linkages for controlling positioning of the leg structure and at least one guide structure for guiding movement of at least one of the linkages.

Dependent claims

A positioning assembly comprising:

a first support structure;
a platform structure rotatably coupled to the first support structure at a pivot and displaceable between a lowered position and a raised position, the first support structure for supporting the platform structure from a surface, the platform structure having a first end and a second end and is adaptable for supporting a mattress thereon, the platform structure defining a longitudinal platform axis;
an actuator extending between the first support structure and the first end of the platform structure for counterbalancing at least the platform structure about the pivot;
and
a second support structure rotatably coupled substantially adjacent the second end of the platform structure, the second support structure capable of displacement between an outward position and an inward position when the platform structure is displaced towards the lowered position and the raised position respectively, said outward position substantially opposite said inward position;
a first linkage slidably coupled to the platform structure, the first linkage being rotatably coupled to the second support structure at one end thereof;
a second linkage rotatably coupled to a link point on the first support structure at one end and rotatably coupled to the other end of the first linkage at the other end thereof;
and
at least one guide structure formed integral the platform structure to limit travel of the first linkage to substantially along the longitudinal platform axis when force applied by the second linkage thereto is angularly displaced from the longitudinal platform axis,
wherein the platform structure extends between and is supported by the first support structure and the second support structure when in the lowered position to thereby dispose the mattress substantially parallel the surface.
