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 disposed on the base;

a support device coupled to the drive mechanism, the support device comprising;

a seating portion;

an arcuate seat support tube extending from one end of the seating portion to another end of the seating portion; and

a housing comprising a supportive housing passage that supports the seat support tube; and

a locking mechanism that secures the seat support tube within the supportive housing passage when the locking mechanism is engaged and allows the seat support tube to slide along at least a portion of the passage when the locking mechanism is disengaged,

wherein the locking mechanism comprises a linkage interconnecting a first wedge-shaped recline locker with a second wedge-shaped recline locker, and a camming mechanism attached to one of the recline lockers such that the camming mechanism actuates one or both recline lockers via the linkage and moves the recline lockers toward or away from each other and either into or out of wedged engagement with the arcuate seat support tube, such that said wedged engagement presses the arcuate seat support tube against an interior surface of the supportive housing passage.

2. The infant care apparatus of claim 1, further comprising a controller electronically coupled to the drive mechanism for controlling the drive mechanism.

3. The infant care apparatus of claim 2, wherein the controller comprises a user interface that is configured to receive user input to control movement of the drive mechanism.

4. The infant care apparatus of claim 2, wherein a seat recline security switch detects whether the locking mechanism has engaged the seat support tube within the housing passage.

5. The infant care apparatus of claim 4, wherein the controller disables the drive mechanism if the locking mechanism is disengaged.

6. The infant care apparatus of claim 1, wherein the drive mechanism comprises a first motion assembly and a second motion assembly.

7. The infant care apparatus of claim 6, wherein the first motion assembly comprises:

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

a first motor operatively connected to the stage.

8. The infant care apparatus of claim 7, wherein the second motion assembly comprises a second motor disposed on the upper surface of the stage of the first motion assembly.

9. The infant care apparatus of claim 8, wherein operation of the first motor imparts motion in a first direction to the stage and operation of the second motor imparts motion in a second direction to the support device.

10. The infant care apparatus of claim 1, wherein the seating portion has a substantially elliptical shape.

11. The infant care apparatus of claim 1, wherein the support device further comprises:

a toy bar having a first end positioned adjacent to one end of the seating portion and a second end extending over the seating portion.

12. An infant care apparatus comprising:

a base; and

a support device supported by the base, the support device comprising;

a seating portion;

an arcuate seat support tube extending from one end of the seating portion to another end of the seating portion; and

a housing comprising a supportive housing passage that supports the seat support tube,

a locking mechanism that secures the seat support tube within the supportive housing passage when engaged and allows the seat support tube to slide along at least a portion of the passage when disengaged, wherein the locking mechanism comprises a linkage interconnecting a first wedge-shaped recline locker with a second wedge-shaped recline locker, and a camming mechanism attached to one of the recline lockers such that the camming mechanism actuates one or both recline lockers via the linkage and moves the recline lockers toward or away from each other and either into or out of wedged engagement with the arcuate seat support tube, such that said wedged engagement presses the arcuate seat support tube against an interior surface of the supportive housing passage,

wherein the arcuate seat support tube is slidingly engaged within at least a portion of the supportive housing passage such that the arcuate seat support tube slides along at least the portion of the supportive housing passage from at least a first position to at least a second position to change an orientation of the seating portion.

13. The infant care apparatus of claim 12, wherein the seating portion has a substantially elliptical shape.

14. The infant care apparatus of claim 12, wherein the support device further comprises:

a toy bar having a first end positioned adjacent to one end of the seating portion and a second end extending over the seating portion.

15. The infant care apparatus of claim 12, further comprising:

a drive mechanism disposed between the base and the support device for imparting motion to the support device.

16. The infant care apparatus of claim 15, wherein the drive mechanism comprises a first motion assembly and a second motion assembly.

17. The infant care apparatus of claim 16, wherein the first motion assembly comprises:

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

a first motor operatively connected to the stage.

18. The infant care apparatus of claim 17, wherein the second motion assembly comprises a second motor disposed on the upper surface of the stage of the first motion assembly.

19. The infant care apparatus of claim 18, wherein operation of the first motor imparts motion in a first direction to the stage and operation of the second motor imparts motion in a second direction to the support device.

20. The infant care apparatus of claim 15, further comprising a controller electronically coupled to the drive mechanism.
