Leg structure for a folding bed

Abstract

An improved leg structure for a folding bed includes a bed frame, a leg part and a support. The support includes at least one first rod and at least one second rod inserted into the first rod. An upper end of the first rod is hinged to a bottom of the bed frame, and another end thereof is a first free end. One end of the second rod is hinged to the bed leg, and another end thereof is a second free end. A positioning mechanism is also included. Accordingly, the unfolding and folding operation of the leg part is more convenient, and a stable supporting effect is also attained.

1 . An improved leg structure for a folding bed comprising a bed frame, a leg part hinged to a bottom of said bed frame, and a support disposed between said bed frame and said leg part, wherein said support includes at least one first rod and at least one second rod inserted into said first rod, an upper end of said first rod being hinged to said bottom of said bed frame, another end of said first rod being defined as a first free end having a circumferential wall defining a rectangular opening and enclosing said second rod, one end of said second rod being hinged to said leg part, another end of said second rod being defined as a second free end having a rectangular cross-section that corresponds in size and shape to said rectangular opening of said first rod to be receivably inserted into said opening of said first rod, a positioning mechanism being disposed for holding said first free end and said second free end in position;
 wherein said positioning mechanism includes a first through hole formed in and extending through said first rod, a second through hole formed in and extending through said second rod, and a movable insert including a pin portion receivable in and extendible completely through said first through hole and said second through hole and a limiting portion mounted to an end of said pin portion to prevent said pin portion from sliding off said first through hole and said second through hole.   
     
     
         2 . (canceled) 
     
     
         3 . The improved leg structure for the folding bed as claimed in  claim 1 , wherein said support is disposed on an outer side of said leg part, said leg part including two feet and a transverse beam connected between said two feet, said second rod being hinged to said transverse beam. 
     
     
         4 . The improved leg structure for the folding bed as claimed in  claim 1 , wherein a protecting sleeve is disposed at said first free end of said first rod.
