Crib frame with lifting device

Abstract

A crib frame includes a lower chassis, an upper chassis, a connecting chassis that connects the lower chassis and upper chassis, and a driving mechanism. The connecting chassis includes a first supporting chassis and a second supporting chassis. The driving mechanism includes an electric motor and an actuator. The first supporting chassis and the second supporting chassis are connected in an “X” shape. One end of the actuator is connected to the first supporting chassis and the other end is connected to the bottom chassis and arranged to control the height of the upper chassis relative to the lower chassis.

1 . A baby crib frame, comprising:
 a bottom chassis;   a top chassis; and   a connecting chassis connected between the top chassis and the top chassis, the connecting chassis including:
 a first support frame having a first pair of parallel support members having lower ends pivotally connected to the bottom chassis and having upper ends that terminate in a first set of rollers that are arranged to roll upon corresponding tracks connected to the top chassis; 
 a second support frame having a second pair of parallel support members having lower ends pivotally connected to the top chassis and having upper ends that terminate in a second set of rollers that are arranged to roll upon corresponding tracks connected to the bottom chassis; and 
 an electric motor and actuator assembly connected between the first and second support frames to adjust the position of the first and second sets of rollers in the corresponding tracks to selectively raise or lower the top chassis relative to the bottom chassis. 
   
     
     
         2 . The baby crib frame of  claim 1  including a foot pedal switch for controlling the motor and actuator assembly. 
     
     
         3 . The baby crib frame of  claim 1  wherein a battery provides electrical power to the electric motor and actuator assembly.
