Motion conversion mechanism for use with child containment structure
First Claim
1. A motion conversion mechanism for use with a child containment structure, the motion conversion mechanism comprising:
- a first member configured to be arranged relative to the child containment structure to undergo motion in a first angular direction and in a second angular direction opposite to the first angular direction;
a second member attached to a rotation device that is rotatable about a rotation axis; and
a first gear member in communication with the first member, and a second gear member in communication with the second member, wherein the first and second gear members intermesh to convert the angular motion of the first member to rotation of the rotation device, wherein the rotation device is driven to rotate when the first member moves both in the first angular direction and in the second angular direction.

Abstract
A motion conversion mechanism is described. The motion conversion mechanism includes a first member and an a second member. The firs member is configured to be arranged relative to the child containment structure to undergo motion in a first angular direction and in a second angular direction opposite to the first angular direction. The second member includes a rotation device that is rotatable about a rotation axis. The first and second members configured in combination to convert motion about the angular motion axis to motion of the rotation device about the rotation axis when the first member moves in at least one of the first angular direction and in the second angular direction.

22. A motion conversion mechanism for use with a child containment structure, the motion conversion mechanism comprising:
-
a first member configured to be arranged relative to the child containment structure to undergo motion about an angular motion axis in a first angular direction and in a second angular direction opposite to the first angular direction; a second member carrying a rotation device that is rotatable relative to the first member about a rotation axis; a first pawl and a second pawl , both pawls carried by the first member; and a first ratchet and a second ratchet rotatable with respect to the first ratchet, wherein the first and second ratchets are configured to engage the first pawl and the second pawl, respectively, wherein movement of the first member in the first angular direction causes the first pawl to engage the first ratchet so as to prevent rotation of the first ratchet and the second pawl to disengage from the second ratchet so as to allow rotation of the second ratchet, and movement of the first member in the second angular direction causes the second pawl to engage the second ratchet so as to prevent rotation of the second ratchet and the first pawl to disengage from the first ratchet to allow rotation of the first ratchet. - View Dependent Claims (23, 24, 25, 26, 27)

28. A child entertainment structure comprising:
-
a support adapted to undergo motion about an angular axis in a first angular direction and a second angular direction opposite to the first angular direction; and a motion conversion mechanism comprising; a first member attached to the support, the first member including at least one ratchet and at least one pawl configured to engage the ratchet in one direction of motion and to disengage the ratchet in a second direction of motion; a second member including a rotation device that is rotatable about a rotation axis, the rotation axis extending in a direction that is not parallel to the angular axis, wherein the pawl and ratchet convert motion of the first member about the angular motion axis to motion of the rotation device about the rotation axis. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A motion conversion mechanism for use with a child containment structure, the motion conversion mechanism comprising:
-
a first member configured to be arranged relative to the child containment structure to undergo motion in a first angular direction and in a second angular direction opposite to the first angular direction; at least one ratchet defining a plurality of ratchet teeth, and at least one pawl in communication with the first member, the pawl configured to engage the ratchet in one direction to prevent rotation of the ratchet, and to disengage and slide along the ratchet teeth in a second direction opposite the first direction to permit rotation of the ratchet; and a second member including a rotation device that is rotatable about a rotation axis, the second member in communication with the ratchet, such that the angular motion of the first member is converted to motion of the rotation device about the rotation axis when the first member moves both in the first angular direction and in the second angular direction.
