Vibrating infant bed

Abstract

The present device is a vibrating infant bed that gently rocks a baby to sleep by providing a smooth, reciprocating movement in the vertical direction. The vibrating mechanism has an A.C. gear motor which rotates an eccentric cam. A cam follower rises on top of the cam and is mounted to the moving plate. The moving plate is guided to move in the vertical direction by bearings. As the cam rotates, the cam follower moves up and down, and so does the moving plate. A timing switch is connected to the motor and can be pre-set for a selected period of operating time.

What I claim as my invention is:  
     
         1 . A vibrating infant bed for providing a vertically reciprocating motion comprising: 
 an infant shell for holding an infant;    a vibrating mechanism connected to said infant shell for transmitting a vertically reciprocating motion to said infant shell;    a base shell for covering said vibrating mechanism;    a timing switch for setting up the operating time of said vibrating mechanism.    
     
     
         2 . The vibrating infant bed as recited in  claim 1  wherein said vibrating mechanism includes an electrical gear motor, a rotating shaft, a coupling which connects said motor to said shaft, two bearings for guiding and supporting said shaft, an eccentric cam, a moving plate assembly, a housing base for mounting said motor and said bearings.  
     
     
         3 . The vibrating infant bed as recited in  claim 2  wherein said cam is driven in circular movement.  
     
     
         4 . The vibrating infant bed as recited in  claim 2  wherein said moving plate assembly includes a cam follower, a moving plate, bearings and supports for guiding said moving plate to move in the vertical direction.  
     
     
         5 . The vibrating infant bed as recited in  claim 4  wherein said moving plate assembly is imparted to move in the vertical direction.  
     
     
         6 . The vibrating infant bed as recited in  claim 5  wherein said cam and said cam follower are kept in contact by springs.  
     
     
         7 . The vibrating infant bed as recited in  claim 6  wherein the operating time of said vibrating mechanism is controlled by a timing switch.
