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 biasing member that biases the reel in such a way that the reel rotates in a winding direction of the string, and a lock member that prohibits rotation of the reel. A biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.
Claims20
A nursery equipment, comprising:
- a fixed portion;
- a movable portion that is movable relative to the fixed portion and that is movable downward in a vertical direction;
- 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 biasing member that biases the reel in such a way that the reel rotates in a winding direction of the string, and
- a lock member that prohibits rotation of the reel, and
- a biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.
A nursery equipment, comprising:
- a fixed portion;
- a movable portion configured to be movable relative to the fixed portion and that is movable downward in a vertical direction;
- 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 biasing member configured to bias the reel in such a way that the reel rotates in a winding direction of the string;
- and
- a lock member configured to prohibit rotation of the reel,
- wherein a biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.
A method for using a nursery equipment, the method comprising:
- rotating a reel of an adjustment mechanism 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;
- and
- locking a lock member of the adjustment mechanism to prohibit rotation of the reel,
- wherein a biasing member of the adjustment mechanism biases the reel in such a way that the reel rotates in a winding direction of the string, and
- wherein a biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.
