Abstract

An infant care apparatus includes a base; a drive mechanism disposed on the base; a controller electronically coupled to the drive mechanism; and a support device coupled to the drive mechanism. The support device is configured to be moved in both a horizontal and vertical direction relative to the base by the drive mechanism. The drive mechanism is controlled by the controller to move the support device in a plurality of motion profiles relative to the base.

Claims

1. An infant care apparatus comprising:

a base;

a drive mechanism coupled to the base and comprising a first motion assembly and a second motion assembly, the first motion assembly comprising;

a first motor having a drive shaft;

a gearing assembly coupled to the drive shaft of the first motor; and

a stage having a lower surface facing the base and an upper surface facing opposite the lower surface, the stage operatively coupled to the gearing assembly, and the second motion assembly comprising at least a second motor disposed on the upper surface of the stage;

a controller electronically coupled to the drive mechanism;

a support device coupled to the second motion assembly, the support device configured to be moved in both a first direction and a second direction relative to the base by the drive mechanism; and

a scissor mechanism disposed on the stage and positioned between the support device and the stage, the scissor mechanism configured to support the support device, the scissor mechanism comprising a first member having a first end operatively connected to the stage and a second end associated with the support device and a second member having a first end operatively connected to the stage and a second end associated with the support device, the first member and the second member operatively connected to each other at central portions thereof,

wherein operation of the first motor imparts motion in the first direction to the stage and operation of the second motor imparts motion in the second direction to the support device,

wherein the second motor has a drive shaft;

a worm gear assembly is coupled to an output of the drive shaft; and

a vertical yoke having a first end is coupled to an output shaft of the worm gear assembly, and

wherein operation of the second motor causes rotation of the vertical yoke, thereby imparting motion in the second direction to the support device.

2. The infant care apparatus of claim 1, wherein the controller is mounted within the base.

3. The infant care apparatus of claim 2, wherein the controller includes a user interface configured to receive input from the user for controlling the movement of the drive mechanism.

4. The infant care apparatus of claim 1, wherein the drive mechanism is controlled by the controller to move the support device in a plurality of visually distinctive motion profiles relative to the base.

5. The infant care apparatus of claim 4, wherein each of the plurality of motion profiles includes both motion in the first direction and motion in the second direction.

6. An infant care apparatus comprising:

a base;

a drive mechanism coupled to the base, the drive mechanism comprising a first motion assembly comprising at least a stage having a lower surface facing the base and an upper surface facing opposite the lower surface; and

a second motion assembly disposed on the upper surface of the stage of the first motion assembly;

a controller electronically coupled to the drive mechanism;

a support device coupled to the drive mechanism, the support device configured to be moved in both a first direction and a second direction relative to the base by the drive mechanism; and

a scissor mechanism disposed on the stage and positioned between the support device and the stage, the scissor mechanism configured to support the support device, the scissor mechanism comprising a first member having a first end operatively connected to the stage and a second end associated with the support device and a second member having a first end operatively connected to the stage and a second end associated with the support device, the first member and the second member operatively connected to each other at central portions thereof,

wherein the first motion assembly further comprises a first motor having a drive shaft and a gearing assembly coupled to the drive shaft of the first motor and operatively coupled to the stage, such that operation of the first motor imparts motion to the stage,

wherein the second motion assembly comprises at least a second motor disposed on the upper surface of the stage and having a drive shaft;

a worm gear assembly coupled to an output of the drive shaft; and

a vertical yoke having a first end is coupled to an output shaft of the worm gear assembly such that operation of the second motor causes rotation of the vertical yoke, thereby imparting motion in the second direction to the support device.

7. The infant care apparatus of claim 6, wherein movement of the support device in the first direction and the second direction is coordinated to obtain at least one motion profile.

8. The infant care apparatus of claim 6, wherein the controller is mounted within the base.

9. The infant care apparatus of claim 8, wherein the controller includes a user interface configured to receive input from the user for controlling the movement of the drive mechanism.

10. The infant care apparatus of claim 6, wherein the drive mechanism is controlled by the controller to move the support device in a plurality of visually distinctive motion profiles relative to the base.

11. An infant care apparatus comprising:

a base;

a drive mechanism coupled to the base and comprising a first motion assembly configured to move in a first direction relative to the base and a second motion assembly configured to move in a second direction relative to the base;

a controller electronically coupled to the drive mechanism;

a support device coupled to the second motion assembly, the support device configured to be moved in both the first direction and the second direction relative to the base by the drive mechanism; and

a scissor mechanism disposed on a stage and positioned between the support device and the stage, the scissor mechanism configured to support the support device, the scissor mechanism comprising a first member having a first end operatively connected to the stage and a second end associated with the support device and a second member having a first end operatively connected to the stage and a second end associated with the support device, the first member and the second member operatively connected to each other at central portions thereof,

wherein the first motion assembly comprises;

a first motor having a drive shaft;

a gearing assembly coupled to the drive shaft of the first motor; and

the stage having a lower surface facing the base and an upper surface facing opposite the lower surface, and

wherein the second motion assembly comprises at least a second motor disposed on the upper surface of the stage and having a drive shaft;

a worm gear assembly is coupled to an output of the drive shaft; and

a vertical yoke having a first end is coupled to an output shaft of the worm gear assembly such that operation of the second motor causes rotation of the vertical yoke, thereby imparting motion in the second direction to the support device.

12. The infant care apparatus of claim 11, wherein the controller is mounted within the base.

13. The infant care apparatus of claim 12, wherein the controller includes a user interface configured to receive input from the user for controlling the movement of the drive mechanism.

14. The infant care apparatus of claim 11, wherein the drive mechanism is controlled by the controller to move the support device in a plurality of visually distinctive motion profiles relative to the base.
