Abstract

A child motion device has a frame assembly configured to rest on a support surface. The frame assembly includes at least one track configured to slidably receive a child seat assembly. The track can extend in any desired direction and include a geometric profile so that as the seat assembly travels along the track, a desired motion profile is imparted onto the seat assembly and to the child seated therein.

Claims

1. A child motion device supported by a support surface, the child motion device comprising:

at least one track defining a travel path and having an arcuate shape with longitudinal outer ends disposed above a midpoint that defines the lowest point along the track;

a seat assembly movably supported on the track; and

a drive assembly propelling the seat assembly along the travel path in a reciprocating manner,

wherein the seat assembly has a momentum and travels along at least a portion of the travel path under gravitational force, and wherein, when the momentum of the seat assembly is overcome by gravity, the seat assembly is driven along the track by the drive assembly.

2. The child motion device as recited in claim 1, wherein the track defines a rail having a contact surface configured to engage at least one wheel for rotation thereon.

3. The child motion device as recited in claim 2, wherein the drive assembly comprises at least one wheel supporting the seat assembly on the rail.

4. The child motion device as recited in claim 3, wherein the drive assembly comprises a drive that actuates the wheel to roll along the rail to move the seat assembly along the travel path.

5. The child motion device as recited in claim 1, wherein the drive assembly further comprises an actuator configured to drive the seat assembly along the travel path.

6. The child motion device as recited in claim 5, further comprising a position sensor and a controller sending control signals to the actuator based on an output from the position sensor.

7. The child motion device as recited in claim 1, wherein the travel path further comprises at least one bump to impart a bouncing motion onto the seat assembly.

8. The child motion device as recited in claim 1, further comprising a pair of the tracks extending substantially parallel to each other, wherein the tracks provide the travel path.

9. The child motion device as recited in claim 1, wherein the seat assembly comprises a removable seat.

10. The child motion device as recited in claim 1, wherein the seat assembly further comprises a seat holder configured to receive and support a child seat in more than one optionally selectable seat facing orientations.

11. The child motion device as recited in claim 10, wherein the child seat can rest on the seat holder in orientations offset substantially 90°

from each other.

12. The child motion device as recited in claim 1, wherein the seat assembly comprises a removable seat configured to be readily secured for use in another device selected from a group consisting of a stroller, a pendulum swing, a bouncer, and a car seat.

13. The child motion device as recited in claim 1, further comprising a frame with a base section supporting the at least one track on the support surface.

14. The child motion device as recited in claim 13, wherein the base section is pivotally coupled to the frame and can be folded to a collapsed configuration.

15. The child motion device as recited in claim 1, wherein the seat assembly comprises a seat that can be adjustably reclined.

16. The child motion device as recited in claim 1, wherein the travel path from one end of the track to the other has a length no more than approximately 6 feet.

17. The child motion device as recited in claim 1, wherein the seat assembly travels along the travel path at a frequency of no more than two minutes per cycle.

18. A child motion device comprising:

a base assembly supported by a support surface;

at least one track supported by the base assembly, the track providing a surface that defines a travel path and having an arcuate shape with longitudinal outer ends disposed above a midpoint that defines the lowest point along the track;

a seat assembly supported by the track, and wherein a child seat of the seat assembly can be oriented in more than one optionally selectable seat facing orientation; and

a drive assembly actuating the seat assembly to drive the seat assembly along the track, wherein the seat assembly reciprocates along the travel path.

19. The child motion device as recited in claim 18, wherein the travel path imparts at least one of a rocking motion, a bouncing motion, and a side-to-side gliding motion onto the seat assembly.

20. The child motion device as recited in claim 18, further comprising a pair of the tracks, wherein the drive assembly further comprises at least one wheel supporting the seat assembly on the pair of tracks, the wheel being rotatable on the track to drive the seat assembly along the track in a reciprocating manner.

21. The child motion device as recited in claim 20, wherein the seat assembly further comprises a seat holder configured to receive and support the child seat in more than one optionally selectable seat facing orientations.

22. The child motion device as recited in claim 21, wherein the child seat can rest on the seat holder in orientations offset substantially 90°

from each other.
