ABSTRACT:
A tiltable bed frame assembly is provided which permits one to adjust the angular disposition of a mattress between a horizontally disposed position and an inclined position, while at the same time permitting one to utilize a conventional mattress, headboard and footboard of a bedroom suit. The tiltable bed frame assembly comprises a main frame and a mattress frame interconnected by a plurality of telescoping members and pivoting support members disposed between the main frame and the mattress frame. The telescoping members are connected by a linkage assembly so that the mattress frame can be pivotally moved between the horizontally disposed position and the inclined position. A locking assembly is supported by the main frame for selectively engaging the linkage assembly and thereby securing the mattress frame in the desired position relative to the main frame. In one embodiment, the tiltable bed frame assembly comprises an elevating assembly for pivoting the mattress frame to the selected angular disposition. The elevating assembly includes a track member, a first support member having a lower end and an opposed upper end, and a power assembly. The lower end of the first support member is slideably supported by the track member and the opposed upper end is pivotably attached to the mattress frame near one end thereof. The power assembly selectively moves the lower end of the first support member along the track member so that the end of the mattress frame is elevated to pivot the mattress frame on the main frame in response to movement of the first support member.
