Spring Bed Foundation

Abstract

A spring bed foundation comprises a first frame body and a second frame body pivotally connected with each other. The first frame body and the second frame body can be folded together so that it is more convenient for transporting the folded spring bed foundation. A plurality of the spring bed foundations can be transported together in order to enhance the economic effectiveness. The folded spring bed foundation can be moved inside a house for assembling more conveniently.

What is claimed is: 
     
         1 . A spring bed foundation, comprising:
 a first frame body comprising a first frame and a first foundation, a plurality of first supporting frames being disposed pivotally and transversely in intervals between the first frame and the first foundation so that the first frame and the first foundation being moved relatively to each other, a first sliding rail being disposed at two opposite sides of the first foundation respectively, the two first sliding rails and each of the first supporting frames intersecting with each other, a first pivotal end being disposed at two sides of an end of the first foundation respectively, a first supporting portion being disposed at two sides of another end of the first foundation respectively, an end of each of the first supporting portions being glidingly disposed on the first sliding rails respectively, another end of each of the first supporting portions being fixed on the first supporting frame furthest away from the first pivotal ends;   a second frame body comprising a second frame and a second foundation, a plurality of second supporting frames being disposed pivotally and transversely in intervals between the second frame and the second foundation so that the second frame and the second foundation being moved relatively to each other, a second sliding rail being disposed at two opposite sides of the second foundation respectively, the two second sliding rails and each of the second supporting frames intersecting with each other, a second pivotal end being disposed at two sides of an end of the second foundation respectively, the second pivotal ends and the first pivotal ends being connected pivotally with each other, a second supporting portion being disposed at two sides of another end of the second foundation respectively, an end of each of the second supporting portions being glidingly disposed on the second sliding rails respectively, another end of each of the second supporting portions being fixed on the second supporting frame furthest away from the second pivotal ends; and   two lateral pivotal pieces connecting to the opposite ends of the first frame and the second frame and being pivotally connected on the first frame and the second frame by two positioning elements respectively.   
     
     
         2 . The spring bed foundation as claimed in  claim 1 , wherein each of the first supporting frames is disposed in the same interval. 
     
     
         3 . The spring bed foundation as claimed in  claim 1 , wherein each of the second supporting frames is disposed in the same interval.
