Abstract

A child motion apparatus includes a base frame assembly for providing standing support on a floor, a column assembled with the base frame assembly, a support arm extending generally horizontally relative to the column and having a first and a second end portion, a child seat connected with the second end portion of the support arm, a vertical actuating mechanism supported by the base frame assembly and operable to drive the column to slide upward and downward, and a horizontal actuating mechanism operable to drive the support arm to oscillate generally horizontally relative to the column. The first end portion of the support arm is assembled with the column and has a channel, and the horizontal actuating mechanism includes a driving part movable along a circular path and guided for sliding movement along the channel at the first end portion of the support arm.

First claim

What is claimed is:

1. A child motion apparatus comprising:
a base frame assembly for providing standing support on a floor;
a column connected with the base frame assembly;
a support arm extending generally horizontally relative to the column, the support arm having a first and a second end portion, the first end portion being assembled with the column and having a channel extending generally vertically, the support arm further being connected with the column via a hinge about which the support arm is rotatable generally horizontally relative to the column;
a child seat connected with the second end portion of the support arm;
a vertical actuating mechanism supported by the base frame assembly and operable to drive the column to slide upward and downward relative to the base frame assembly; and
a horizontal actuating mechanism operable to drive the support arm to oscillate generally horizontally relative to the column, the horizontal actuating mechanism including a driving part movable along a circular path and guided for sliding movement along the channel at the first end portion of the support arm, wherein a circular motion of the driving part causes the driving part to slide along the channel and thereby drives an oscillating movement of the support arm.

2. The child motion apparatus according to claim 1 , wherein the channel has a length that encompasses a diameter of the circular path.

3. The child motion apparatus according to claim 1 , wherein the driving part is a roller or a ball bearing.

4. The child motion apparatus according to claim 1 , wherein the horizontal actuating mechanism further includes:
an electric motor having an output shaft; and
a transmission assembly respectively coupled with the output shaft of the electric motor and the driving part, the transmission assembly including a gear rotatable about an axis extending generally horizontally, the driving part being attached to the gear.

5. The child motion apparatus according to claim 4 , wherein the transmission assembly further includes:
a first pulley affixed with the output shaft of the electric motor;
a worm shaft having a worm and affixed with a second pulley;
a belt connected with the first and second pulleys;
a worm gear meshed with the worm; and
a second gear rotationally coupled with the worm gear, the second gear meshing with the gear attached to the driving part.

6. The child motion apparatus according to claim 1 , wherein the column includes a second channel, and the vertical actuating mechanism includes a second driving part movable along a second circular path and guided for sliding movement along the second channel.

7. The child motion apparatus according to claim 6 , wherein the second channel of the column extends generally horizontally.

8. The child motion apparatus according to claim 6 , wherein the driving part of the horizontal actuating mechanism and the second driving part of the vertical actuating mechanism respectively move in two generally vertical planes that are parallel or substantially parallel to each other.

9. The child motion apparatus according to claim 6 , wherein the second channel extends generally horizontally, and has a length that encompasses a diameter of the second circular path.

10. The child motion apparatus according to claim 6 , wherein the second driving part is a roller or a ball bearing.

11. The child motion apparatus according to claim 6 , wherein the vertical actuating mechanism further includes:
a second electric motor having a second output shaft; and
a second transmission assembly coupled with the second output shaft of the second electric motor and including a crank rotatable about an axis extending generally horizontally, the second driving part being attached to the crank.

12. The child motion apparatus according to claim 11 , wherein the second transmission assembly further includes:
a third pulley affixed with the second output shaft;
a second worm shaft having a second worm and affixed with a fourth pulley;
a second belt connected with the third and fourth pulleys; and
a second worm gear meshed with the second worm and rotationally coupled with the crank.

13. The child motion apparatus according to claim 1 , wherein the column includes a plurality of pockets, and the support arm includes a plurality of converging portions respectively in contact with the pockets to form the hinge allowing generally horizontal rotation of the support arm relative to the column, the respective contacts between the converging portions and the pockets being substantially aligned with each other along a vertical axis.

14. The child motion apparatus according to claim 1 , wherein the second end portion of the support arm is affixed with a seat mount, and the child seat is affixed with a connector, the connector being engageable with the seat mount in different orientations of the child seat relative to the column.

15. The child motion apparatus according to claim 1 , wherein the base frame assembly includes a housing, and one or more stabilizing foot detachably connected with the housing.

16. The child motion apparatus according to claim 1 , wherein the child seat includes a support frame having two curved foot portions, the curved foot portions allowing the child seat to rock on a floor surface when the child seat is removed from the support arm and used as a standalone chair.

17. The child motion apparatus according to claim 16 , wherein the second end portion of the support arm is affixed with a seat mount, and the child seat further includes a connector disposed between the two foot portions, the connector being engageable with the seat mount in different orientations of the child seat.

18. The child motion apparatus according to claim 17 , wherein the child seat further includes a surrounding frame pivotally connected with the support frame, the surrounding frame being rotatable relative to the support frame for recline adjustment.

19. The child motion apparatus according to claim 18 , wherein the child seat further includes two vertically slidable struts respectively connected with a left and a right side of the surrounding frame and the two foot portions, and at least one latch operable to lock the surrounding frame with the support frame in a recline position.

20. The child motion apparatus according to claim 1 , wherein the horizontal actuating mechanism further includes:
an electric motor having an output shaft;
a transmission assembly respectively coupled with the output shaft of the electric motor and the driving part, the transmission assembly including a first and a second gear, the second gear being affixed with the driving part; and
a housing respectively assembled with the electric motor and the first gear, the housing being connected with a casing of the column via an attachment that allows a limited rotation of the housing relative to the casing sufficient to disengage the first gear from the second gear.

21. A child motion apparatus comprising:
a base frame assembly for providing standing support on a floor;
a column connected with the base frame assembly;
a support arm extending generally horizontally relative to the column, the support arm having a first and a second end portion, the first end portion being assembled with the column and having a first channel extending generally vertically, the support arm further being connected with the column via a hinge about which the support arm is rotatable generally horizontally relative to the colu
