Abstract

An adjustable mode child rocker can be adjusted to provide a number of different swinging/rocking motions to a child positioned within the rocker. The child rocker can include a seat assembly that can include a seat upon which a child can sit. The child rocker can also include a trolley assembly that is directly or indirectly attached to the seat assembly and can include multiple wheels near the bottom of the trolley assembly. The child rocker can also include at least one stationary track and at least one adjustable track for the wheels to move along to provide the different rocking/swinging motions to the seat assembly. The adjustable track(s) is adjustable from at least a first position to a second position to change the distance between the troughs of the respective stationary and adjustable tracks along a longitudinal axis of the child rocker and thereby changing the rocking/swinging motion.

First claim

What is claimed is:

1. An adjustable child rocker comprising:
a seat assembly comprising a seat configured to receive a child;
a trolley assembly operably coupled to the seat assembly and comprising a plurality of wheels;
at least one stationary track;
a first adjustable track; and
a second adjustable track, wherein the first adjustable track is adjustable from at least a first position to a second position and the second adjustable track is adjustable from at least a third position to at least a fourth position;
wherein a first wheel of the plurality of wheels moves along the at least one stationary track, a second wheel of the plurality of wheels moves along the first adjustable track, and a third wheel of the plurality of wheels moves along the second adjustable track.

2. The adjustable child rocker of claim 1 , wherein each of the at least one stationary track, the first adjustable track and the second adjustable track comprises an arcuate track and wherein the first wheel engages a first arcuate track on the at least one stationary track, the second wheel engages a second arcuate track on the first adjustable track, and the third wheel engages a third arcuate track on the second adjustable track.

3. The adjustable child rocker of claim 1 , further comprising:
a housing comprising a base bottom and a housing cover, wherein the base bottom and housing cover define a housing cavity; and
an adjustable track platform disposed within the housing cavity and adjustable with respect to the base bottom, wherein the first adjustable track and the second adjustable track are disposed on the adjustable track platform.

4. The adjustable child rocker of claim 3 , further comprising an adjustable track drive disposed on the adjustable track platform.

5. The adjustable child rocker of claim 4 , further comprising a gear disposed adjacent the base bottom and having a first longitudinal axis substantially parallel to a longitudinal axis of the base bottom;
wherein the adjustable track drive engages the gear to adjust the first adjustable track from at least the first position to the second position and adjust the second adjustable track from at least the third position to the fourth position.

6. The adjustable child rocker of claim 4 , wherein the adjustable track drive comprises:
a motor; and
a transmission operably coupled to the motor.

7. The adjustable child rocker of claim 1 , wherein the trolley assembly comprises:
a central hub;
a first mounting panel extending from the central hub and comprising the first wheel and a fourth wheel of the plurality of wheels;
a first track arm comprising a first end coupled to the central hub and a distal second end coupled to the second wheel of the plurality of wheels;
a second track arm comprising a first end coupled to the central hub and a distal second end coupled to the third wheel of the plurality of wheels; and
a seat mounting dock configured to be removably coupled to the seat assembly.

8. The adjustable child rocker of claim 7 , wherein the first wheel and the fourth wheel are drive wheels coupled to a seat drive system.

9. The adjustable child rocker of claim 8 , wherein the seat drive system is coupled to the trolley assembly.

10. The adjustable child rocker of claim 8 , wherein the seat drive system comprises:
a motor;
a transmission operably coupled to the motor; and
a drive shaft operably coupled to the transmission;
wherein the first wheel and the fourth wheel are coupled to the drive shaft.

11. The adjustable child rocker of claim 7 , wherein the seat mounting dock comprises:
an annular ring body; and
a plurality of slots disposed in the annular ring body.

12. The adjustable child rocker of claim 11 , wherein the plurality of slots comprises four slots and wherein each of the fours slots is disposed through the annular ring body at 90 degree intervals about the annular ring body.

13. The adjustable child rocker of claim 1 , wherein the at least one stationary track comprises a first stationary track and a second stationary track and wherein at least a portion of the first adjustable track and the second adjustable track is disposed between the first stationary track and the second stationary track.

14. The adjustable child rocker of claim 13 , wherein the first stationary track comprises a first longitudinal axis, the second stationary track comprises a second longitudinal axis, the first adjustable track comprises a third longitudinal axis, and the second adjustable track comprises a fourth longitudinal axis and wherein the first longitudinal axis, the second longitudinal axis, the third longitudinal axis, and the fourth longitudinal axis are substantially parallel.

15. The adjustable child rocker of claim 1 , further comprising:
a processor;
a control panel communicably coupled to the processor;
an adjustable track drive communicably coupled to the processor and operably coupled to the first adjustable track and the second adjustable track to move the first adjustable track from the first position to the second position and the second adjustable track from the third position to the fourth position; and
a seat drive communicable coupled to the processor and operably coupled to the trolley assembly.

16. The adjustable child rocker of claim 15 , wherein the adjustable track drive is further configured to move the first adjustable track from the second position to a fifth position and from the fifth position to a sixth position and configured to move the second adjustable track from the fourth position to a seventh position and from the seventh position to an eighth position,
wherein when the first adjustable track is in the first position and the second adjustable track is in the third position, the trolley assembly generates a rocking motion at the seat assembly,
wherein when the first adjustable track is in the second position and the second adjustable track is in the fourth position, the trolley assembly generates a glide motion at the seat assembly,
wherein when the first adjustable track is in the fifth position and the second adjustable track is in the seventh position, the trolley assembly generates a swing motion at the seat assembly, and
wherein when the first adjustable track is in the sixth position and the second adjustable track is in the eighth position, the trolley assembly generates a cradle motion at the seat assembly.

17. The adjustable child rocker of claim 1 , wherein each of the at least one stationary track, first adjustable track, and second adjustable track comprises:
a substantially flat track surface;
a wall extending up from the substantially flat track surface; and
an elongated slot disposed through the wall.

18. A method of changing a swing mode for an adjustable child rocker from a first swing mode to a second swing mode, comprising:
providing the child rocker comprising:
a seat assembly comprising a seat configured to receive a child;
a trolley assembly operably coupled to the seat assembly and comprising a first guide wheel, a second guide wheel, a first drive wheel, and a second drive wheel;
a first stationary track, wherein the first guide wheel abuts the first stationary track;
a second stationary track, wherein the second guide wheel abuts the second stationary track;
a first adjustable track, wherein the first drive wheel abuts the first adjustable track; and
a second adjustable track, wherein the second drive wheel abuts the second adjustable track and wherein the first adjustable track is adjustable from at least a fir
