Descripción
    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to a crib including a tilting device and a rotating device for respectively tilting and rotating the bed frame such that the baby can be arranged in a specific pose for avoiding from throwing up.
  • BACKGROUND OF THE INVENTION
  • [0002]
    A conventional baby bed simply includes a headboard, a footboard, two rails and a bed frame which connected between the headboard and the footboard. The two rails prevent the baby from dropping from the crib. A pad or a mattress is put on the bed frame which is arranged horizontally and the baby lies on the pad with a pillow for supporting the baby's head. Applicant's former invention for supporting baby's head is disclosed in U.S. Pat. No. 6,263,526 which discloses a head forming cot. However, the former invention only provide an ideal support to the head, after the baby had milk, the parents usually pet the back of the baby and try to release the air in the stomach. The purpose of petting is to reduce the possibility of throwing up of the milk. Nevertheless, because the milk is liquid and the baby cannot sit or stand so that the liquid food tends to flow back through the esophagus and this sometimes is dangerous for the baby. A lot of air enters the stomach during having milk so that the pressure in the stomach is increased and the baby's cardiac sphincter is not strong enough to prevent the flowing of the milk from the stomach. Therefore, the baby is suffered by the throwing of milk when the baby lies horizontally in the crib. Ideally, if the head of the baby is arranged to be slightly higher than the stomach, and because the stomach is located at the left side of the baby's body, so that if the left side of the baby lies slightly higher than the right side of the baby, the food in the stomach easily enters the duodenum which is located at the right side of the baby.
  • [0003]
    The present invention intends to provide an adjustable crib which includes a tilting device for raising the head end of the bed frame and a rotating device which rotates the left side of bed frame to be higher than the right side.
  • SUMMARY OF THE INVENTION
  • [0004]
    The present invention relates to an adjustable crib that comprises a base and a bed frame connected to the base. A tilting device is connected to the base so as to raise an end of the bed frame. A rotating device is connected to the base and rotates the bed frame. So as to prevents the baby from throwing up after having milk.
