Folding structure for bed leg of bed frame and bed frame

Abstract

A folding structure for a bed leg of a bed frame includes a bed frame body, a frame, and the bed leg. The frame comprises a supporting rod, and a connecting rod is pivotally connected to the sliding seat and the bed leg. The supporting rod, the connecting rod, and the bed leg form a triangular supporting structure, and the connecting rod is operatively coupled to the bed leg to enable folding and unfolding of the bed leg and to enable the connecting rod to be operatively coupled to the sliding seat to have an amount of displacement along a length direction of the supporting rod. The amount of displacement enables the bed leg to be in a folded state or an unfolded state. A locking device is disposed on the supporting rod for locking the sliding seat to enable the bed leg to be maintained in the unfolded state.

         4 . The folding structure for the one or more bed legs of the bed frame according to  claim 3 , wherein:
 the snap portion comprises a U-shaped groove and a guiding-in slope,   the guiding-in slope is defined by an end surface of the snap portion inclining toward the U-shaped groove,   an opening of the U-shaped groove faces the supporting rod of the frame,   when the one or more bed legs are unfolded, the one or more sliding seats are configured to slide toward the U-shaped seat, and the snap member is configured to abut the guiding-in slope to be further moved along the guiding-in slope to press an end of the U-shaped seat downward, so as to make the snap portion rotate downward around the pivoting end to enable the snap member to be snapped into the U-shaped groove, and   while the snap member is snapped into the U-shaped groove:
 an elastic force of the spring drives the snap portion to rotate upward around the pivoting end to be reset to an initial position, and 
 the snap member in the U-shaped groove and the supporting rod form the position inhibiting connection. 
   
     
     
         5 . The folding structure for the one or more bed legs of the bed frame according to  claim 3 , wherein:
 a locking chamber is defined between the snap portion and the supporting rod, and   the spring is driven by an external force to form the elastic deformation to drive the snap portion to be adjacent to or separated from the supporting rod of the frame to cooperate with the snap member to form or terminate the position inhibiting connection.   
     
     
         6 . The folding structure for the one or more bed legs of the bed frame according to  claim 4 , wherein:
 each of the one or more sliding seats comprises a U-shaped sliding groove,   the U-shaped sliding groove is sleeved on the supporting rod using a connecting member, and   the connecting member is the snap member.   
     
     
         7 . The folding structure for the one or more bed legs of the bed frame according to  claim 4 , wherein:
 the one or more bed legs comprise two bed legs disposed on two opposite sides of the frame,   the one or more locking devices comprises two locking devices configured to correspond to the two bed legs,   a linking rod is disposed between the U-shaped seats of the two locking devices, and   a rotation of a first one of the snap portions of the U-shaped seats of the two locking devices is operatively coupled to a rotation of a second one of the snap portions of the U-shaped seats of the two locking devices through the linking rod.   
     
     
         8 . The folding structure for the one or more bed legs of the bed frame according to  claim 7 , wherein:
 when the snap portions of the U-shaped seats of the two locking devices are rotated to be in a locked state, the linking rod supports ribs defining a support surface of the bed frame body.   
     
     
         9 . The folding structure for the one or more bed legs of the bed frame according to  claim 1 , wherein:
