Abstract
Abstract A knockdown type of bed frame constructed predominantly from plastic components. The bed frame includes a pair of parallel side-tube members and a pair of cross-tube members. The end positions of the side-tube members and the cross-tube members are received in corresponding sockets formed in floor engaging leg members. Means are provided for retaining the side-tube members and the cross-tube members within the sockets formed in the leg members. The leg members are formed with substantially horizontal surfaces for receipt of mattress means thereon. The leg members are provided with floor engaging means. In accordance with one embodiment of the invention the floor engaging means is a caster wheel assembly incorporating a brake mechanism for applying a braking action to a caster wheel upon application of a predetermined downward force thereto. In accordance with another embodiment of the invention the floor engaging means is a glide assembly which incorporates means to facilitate initial movement thereof over a carpeted floor.
