Abstract

Rotation device is configured at the bottom of the body of a diaper changer so that the diaper changer is capable of rotating horizontally relative to the playard frame via the rotation device when mounting thereon. The rotation device includes a rotator and a supporter where the rotator connects to the body and mounts on the supporter for allowing the body to rotate relative to the supporter. The supporter is further configured at one side of the playard frame. The body can also be rotatably mounted on the playard frame by mounted the rotator directly into a shafting hole on the playard frame. With the rotation device, the diaper changer can be selectively set in a first using status for changing a baby's diaper or a second using status for allowing a babysitter for easy holding the baby up.

Claims (38)

1. A diaper changer for a playard frame, comprising:

a body which includes a surface for a baby lying thereon; and

a rotation device connecting to the body, the rotation device mounted on one side of the playard frame, the rotation device comprising a supporter having two coupling ends detachably mounted to two top corners of the playard frame respectively;

wherein the body is maintained horizontally for supporting the baby when changing from a first using status to a second using status via the rotation device.

2. The diaper changer of claim 1 , wherein the rotation device comprises a supporter and a rotator, the rotator connected to the body with one end and rotatably mounted to the supporter with the other end, the supporter mounted on the side of the playard frame, the body rotatable relative to the supporter via the rotator.

3. The diaper changer of claim 2 , wherein the rotator comprises a shaft and the supporter comprises a shafting hole, the shaft rotatably mounted within the shafting hole.

4. The diaper changer of claim 2 , wherein the supporter comprises a coupling portion and a pipe portion extending from the coupling portion and the rotator comprises a hollow axle portion sleeved on the pipe portion so as to allow the body for rotating relative to the supporter.

5. The diaper changer of claim 4 , wherein the supporter further comprises a limiter capable of abutting against the axle portion for limiting relative movement of the axle portion to the pipe portion.

6. The diaper changer of claim 5 , wherein the pipe portion is hollow and the limiter is a V-shape elastic element placed in the hollow pipe portion, the elastic element having a protrusion that extends outward the pipe portion for abutting against the wall of the axle portion.

7. The diaper changer of claim 2 , wherein the supporter comprises a first engaging device and the rotator comprises a second engaging device for engaging with the first engaging device so that the body is selectively fixed in the first using status or in the second using status relative to the playard frame.

8. The diaper changer of claim 7 , wherein the first engaging device is a bulge and the second engaging device is an indentation.

9. The diaper changer of claim 1 , wherein the first using status is a position the baby lying with its feet toward a babysitter and the second using status is a position the baby lying laterally toward the babysitter.

10. The diaper changer of claim 1 , wherein the playard frame comprises a shafting hole on one side and the rotation device comprises a shaft rotatably mounted within the shafting hole.

11. A playard, comprising:

a playard frame comprising at least two top corners; and

a diaper changer, comprising:

a body for supporting a baby; and

a rotation device connecting to the body, the rotation device mounted on one side of the playard frame and rotatable along a first direction, the rotation device comprising a supporter having two coupling ends detachably mounted to the two top corners respectively;

wherein the body is capable of selectively set horizontally for supporting the baby either in a first using status or in a second using status relative to the playard frame via the rotation device.

12. The playard of claim 11 , wherein the rotation device further comprises a rotator, the rotator connected to the body with one end and rotatably mounted to the supporter with the other end, the supporter mounted on the side of the playard frame, the body rotatable relative to the supporter via the rotator.

14. The playard of claim 12 , wherein the supporter comprises a coupling portion and a pipe portion extending from the coupling portion and the rotator comprises a hollow axle portion sleeved on the pipe portion so as to allow the body for rotating relative to the supporter.

15. The diaper changer of claim 14 , wherein the rotator further comprises a disk at the bottom of the axle portion, the disk has at least an indentation, and the coupling portion comprises a concave portion for containing the disk and has at least a bulge on the concave portion for engaging with the indentation so that the rotation angle of the body relative to the supporter can be fixed.

16. The playard of claim 11 , wherein the first direction is horizontal direction.

17. The playard of claim 11 , wherein the playard frame comprises a shafting hole mounted on one side and the rotation device comprises a shaft rotatably inserted in the shafting hole.

18. The playard of claim 11 , wherein the first using status is a position the baby lying with its feet toward a babysitter and the second using status is a position the baby lying laterally toward the babysitter.

19. A diaper changer for a playard frame, comprising:

a body for supporting a baby; and

a rotation device connecting to the body, the rotation device mounted on one side of the playard frame;

wherein the body is maintained horizontally with a first portion of the body and a second portion of the body located at opposite sides of the playard frame while rotating the body relative to the playard frame via the rotation device, the first portion of the body extending above an outside of the playard frame and the second portion of the body extending above an inside of the playard frame.
