发明名称 Foldaway bed frames and spring supports
摘要 A folding bed frame utilizes a spring support bracket that is located intermediate a bed support frame and a mattress support frame. Separate pairs of tensioning springs attach the spring support bracket to the bed support frame and to the mattress support frame. This tiered spring arrangement provides an enhanced counterweighting force to the mattress support frame, assisting a user when raising or lowering the bed. Additionally, a hanger is attached to a rear surface of a front panel to assist in the proper positioning of the panel prior to its attachment to the mattress support frame.
