Description
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.
[0005] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

invention, and
[0010] FIG. 5 shows that one end of the bed frame is raised by the
titling device.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Referring to FIGS. 1, 2 and 3, the adjustable crib of the
present invention comprises a base 10 and a bed frame 20 which is
connected to the base 10 and can be rotatable about an axle 11
relative to the base 10. The bed frame 20 may include fastening
members 70 connected to two sides of the bed frame 20. The
fastening members 70 can be belts so as to position baby in the bed
frame 20.
[0012] A tilting device 30 includes a titling mechanism 31 and is
connected to an end of the base 10 and able to pitch the bed frame
20, i.e. able to raise the front end of the bed frame 20. The
tilting device 30 maybe has many embodiments for raising the bed
frame 20, and may be manual or automatic. In an embodiment of the
present invention for an automatic way, the tilting mechanism 31
includes an electric motor 32 which is fixed to the base 10 and
drives first and second pushing rods 33, 330 to extend relative to
the base 10 so as to raise an end of the bed frame 20. The first
and second pushing rods 33, 330 are located at two sides of the end
of the bed frame 20 and are respectively and movably guided by
first and second rails 35, 350 which ensure the first and second
pushing rods 33, 330 to extend smoothly. The first and second
pushing rods 35, 350 have first and second racks 36, 360
respectively connected thereto. A first passive gear 37 and a
second passive gear 370 are respectively connected to the base 10
and engaged with the first and second racks 36, 360. A shaft 38 is
connected between the first and second passive gears 37, 370. The
electric motor 32 has an output shaft 320 and an active gear 34 is
connected to the output shaft 320. The active gear 34 is engaged
with the first passive gear 37 so that the electric motor 32 drives
first passive gear 37 directly and the second passive gear 370
indirectly via the shaft 38. The first and second passive gears 37,
370 are rotated so as to move the first and second racks 36, 360
which extend the first and second pushing rods 33 330 so that an
end of the bed frame 20 can be raised as shown in FIG. 5. Two
casters 39, 390 (FIG. 3) are respectively connected to the first
and second pushing rods 33, 330 for convenience of moving the
crib.
[0013] Further referring to FIG. 4, the electric motor 32 is
connected to a control device 50 which includes a motor driving
control unit 51, a signal input device 53 having a signal input
unit 52, and a signal processing unit 54. A further embodiment of
the present invention for a remote controlling way, the signal
input device 53 includes a signal emitting device 56 such as a
remote controller and a signal receiving device 55 which receives
signals sent from the signal emitting device 56 and passes the
signals to the signal input unit 52 of the signal input device
53.
[0014] Referring to FIG. 3, a rotating device 40 is connected to
the base 10 and able to roll the bed frame 20, i.e. to rotate the
bed frame 20 about a central axle 11 of the bed frame 20 so that
the left side of the baby's body can be arranged to be slightly
higher than the right side. The rotating 40 maybe has many
embodiments for automatic rotating the bed frame 20, In an
embodiment of the present invention, the rotating device 40
includes a transmission device 41 which includes an electric motor
42 so as to rotate the bed frame 20 relative to the base 10. A
plurality of passive wheels 22 is connected along a circular
periphery at an end of the bed frame 20 and rotatable about the
central axle 11 of the bed frame 20. The electric motor 42 has an
active wheel 420 engaged with the passive wheels 22 so that the bed
frame 20 is rotated about the axle 11 when activating the electric
motor 42.
[0015] The electric motor 42 is connected to a control device 60
which includes a motor driving control unit 61, a signal input
device 63 having a signal input unit 62, and a signal processing
unit 64. A further embodiment of the present invention for a remote
controlling way, the signal input device 63 includes a signal
emitting device 66 such as a remote controller and a signal
receiving device 65 which receives signals sent from the signal
emitting device 66 and passes the signals to the signal input unit
62 of the signal input device 63.
[0016] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
