Abstract
An adjustment mechanism of nursery equipment includes a string connecting a fixed portion and a movable portion, a reel that is rotatable in both forward and reverse directions and that changes the position or shape of the movable portion by winding up and feeding out the string, a rotation operation member that controls rotation of the reel, a motion transmission portion that transmits a rotational motion of the rotation operation member to the reel, and a motion separation portion that does not transmit the rotational motion of the rotation operation member to the reel.
Claims20
A nursery equipment, comprising:
- a fixed portion;
- a movable portion that is movable relative to the fixed portion;
- and
- an adjustment mechanism that adjusts a position or shape of the movable portion, wherein the adjustment mechanism includes:
- a string connecting the fixed portion and the movable portion,
- a reel that is rotatable in both forward and reverse directions and that changes the position or shape of the movable portion by winding up and feeding out the string,
- a rotation operation member that controls rotation of the reel,
- a motion transmission portion that transmits a rotational motion of the rotation operation member to the reel, and
- a motion separation portion that does not transmit the rotational motion of the rotation operation member to the reel, wherein the motion transmission portion or the motion separation portion includes a drive gear portion and a driven gear portion meshed with the drive gear.
A nursery equipment, comprising:
- a fixed portion;
- a movable portion configured to be movable relative to the fixed portion;
- and
- an adjustment mechanism configured to adjust a position or shape of the movable portion, the adjustment mechanism comprising:
- a string connecting the fixed portion and the movable portion;
- a reel configured to be rotatable in both forward and reverse directions and to change the position or shape of the movable portion by winding up and feeding out the string;
- a rotation operation member configured to control rotation of the reel;
- a motion transmission portion configured to transmit a rotational motion of the rotation operation member to the reel;
- and
- a motion separation portion that does not transmit the rotational motion of the rotation operation member to the reel, wherein the motion transmission portion or the motion separation portion comprises a drive gear portion and a driven gear portion meshed with the drive gear.
A method for using a nursery equipment, the method comprising:
- controlling a rotation operation member to cause a motion transmission portion of an adjustment mechanism of the nursery equipment to transmit a rotational motion of the rotation operation member to rotate a reel of the nursery equipment in a forward direction or a reverse direction to change a position or shape of a movable portion of the nursery equipment connected to a fixed portion of the nursery equipment via a string by winding up and feeding out the string,
- wherein a motion separation portion of the adjustment mechanism of the nursery equipment does not transmit the rotational motion of the rotation operation member to the reel, and
- wherein the motion transmission portion or the motion separation portion comprises a drive gear portion and a driven gear portion meshed with the drive gear.
