Abstract

An infant bed apparatus includes a support frame, a bed frame for defining an interior space suitable for receiving a child, and a motorized drive unit. The support frame includes a first and a second housing disposed at two locations spaced-apart from each other along a lengthwise axis of the infant bed apparatus. The bed frame has a first portion anchored with the first housing, and a second portion assembled with the second housing. The motorized drive unit is operable to drive the second portion of the bed frame in movement relative to the second housing.

First claim

What is claimed is:

1. An infant bed apparatus comprising:
a support frame including a first and a second housing disposed at two locations spaced-apart from each other;
a bed frame defining an interior space suitable for receiving a child, the bed frame having a first portion anchored with the first housing, and a second portion assembled with the second housing, the first portion of the bed frame being rotatable relative to the first housing about a pivot axis that extends substantially vertical; and
a motorized drive unit operable to drive the second portion in translational movement relative to the second housing.

2. The infant bed apparatus according to claim 1 , wherein the motorized drive unit is disposed in the second housing.

3. The infant bed apparatus according to claim 1 , wherein the first housing is located proximate to a foot region of the bed frame, and the second housing is located proximate to a head region of the bed frame.

4. The infant bed apparatus according to claim 1 , wherein the first housing includes a power source for supplying electric power to the motorized drive unit.

5. The infant bed apparatus according to claim 4 , wherein the motorized drive unit is disposed in the second housing, and the power source is electrically connected with the motorized drive unit via a wiring that is routed through the support frame.

6. The infant bed apparatus according to claim 1 , wherein the first portion of the bed frame is pivotally connected with the first housing about the pivot axis that extends substantially vertical.

7. The infant bed apparatus according to claim 1 , wherein the first portion of the bed frame is anchored with the first housing via a spherical joint.

8. The infant bed apparatus according to claim 1 , wherein the first portion of the bed frame is anchored with the first housing via a webbing strap.

9. The infant bed apparatus according to claim 1 , wherein the second portion is assembled with the second housing via a coupling member, and the motorized drive unit is operable to cause a movement of the coupling member in a substantially horizontal plane.

10. The infant bed apparatus according to claim 1 , wherein the second portion is assembled with the second housing via a coupling member, and the motorized drive unit is operable to cause a spatial motion of the coupling member that includes a horizontal component and a vertical component.

11. The infant bed apparatus according to claim 1 , wherein the second portion is assembled with the second housing via a coupling member, the second housing includes a guide track, and the coupling member is provided with a wheel in rolling contact with the guide track.

12. The infant bed apparatus according to claim 1 , wherein the second portion is assembled with the second housing via a coupling member, and the motorized drive unit includes:
a motor having an output shaft;
a worm connected with the output shaft;
a worm gear meshed with the worm;
a first spur gear connected with the worm gear;
a second spur gear larger than and meshed with the first spur gear; and
a linkage having two opposite ends respectively connected pivotally with the second spur gear and the coupling member.

13. The infant bed apparatus according to claim 1 , wherein the second portion is assembled with the second housing via a coupling member, and the motorized drive unit includes:
a motor having an output shaft;
a crank having a first and a second end; and
a first and a second bar linkage, the first bar linkage having a third and a fourth end, and the second bar linkage having a fifth and a sixth end;
wherein the first end is connected with the output shaft of the motor, the second and the third ends are pivotally connected with each other, the fourth and the fifth ends are pivotally connected with each other via a pivot shaft, and the sixth end is pivotally connected with the first housing.

14. The infant bed apparatus according to claim 13 , wherein the coupling member is an elongated rod having a seventh and an eighth end, the seventh end being pivotally connected with the pivot shaft, and the eighth end being connected with the second portion of the bed frame.

15. The infant bed apparatus according to claim 1 , wherein the support frame includes a curved foot portion adapted to rock on a ground surface, and at least one of the first and second housings includes a stabilizer foot operable to fold onto and deploy from the housing.

16. The infant bed apparatus according to claim 1 , wherein each of the first and second housings respectively includes a latch operable to engage with an attachment structure that is configured to attach a bassinet to a play yard.

17. The infant bed apparatus according to claim 1 , wherein each of the first and second housings respectively includes a latch operable to engage with an attachment structure that is configured to fasten onto a play yard.

18. The infant bed apparatus according to claim 16 , wherein one of the first and second housings includes a first latch, and the other one of the first and second housings includes a second latch, the first latch projecting from a downwardly facing surface, and the second latch projecting from a substantially vertical surface.

19. The infant bed apparatus according to claim 18 , wherein when the infant bed apparatus is installed on a play yard having an attachment structure, the downwardly facing surface is adapted to rest against a support surface of the attachment structure at an inner side of the play yard.

20. An infant bed apparatus comprising: a support frame including a first and a second housing disposed at two locations spaced-apart from each other along a lengthwise axis of the infant bed apparatus, the lengthwise axis corresponding to a direction of placement of a child in the bed frame, the support frame further including a curved foot portion adapted to rock on a ground surface, and at least one of the first and second housings including a stabilizer foot operable to fold onto and deploy from the housing; a bed frame defining an interior space suitable for receiving the placement of a child with the head and legs of the child disposed generally along the lengthwise axis, the bed frame having a first portion pivotally connected with the first housing and a second portion assembled with the second housing; and a motorized drive unit disposed in the second housing and operable to drive the second portion in movement relative to the second housing so as to cause a displacement of the second portion of the bed frame laterally relative to the lengthwise axis.

21. The infant bed apparatus according to claim 20 , wherein the first housing is located proximate to a foot region of the bed frame, and the second housing is located proximate to a head region of the bed frame.

22. The infant bed apparatus according to claim 20 , wherein the first housing includes a power source for supplying electric power to the motorized drive unit.

23. The infant bed apparatus according to claim 22 , wherein the power source is electrically connected with the motorized drive unit via a wiring that is routed through a foot portion of the support frame.

24. The infant bed apparatus according to claim 20 , wherein the second portion is assembled with the second housing via a coupling member, and the motorized drive unit is operable to cause a movement of the coupling member in a substantially horizontal plane.
