Place so that when seat 7 deviates to the left, counterweight 1 can deviate to the right accordingly, balancing pole 13 itself can be relatively fixed axis
5 and telescopic shaft 11 rotate, since fixed position is in position of centre of gravity, there are one physics centers of gravity for each object, as long as having found
Its equalization point, so that it may to go to manipulate it with minimum strength；
Children can shake seat 7 during movable so that seat 7 is swung, and ground is placed in since chair frame 2 is fixed on
On, it plays one and slows down and eliminate this active force for shaking and bringing, seat 7 is kept to be in the core of equilibrium state always
Position is exactly the first universal joint 10, it can be with the weight of support whole equipment, while the low friction resistance function of offer can effectively subtract
It is influenced less with isolation applied external force, seat 7 is made to remain the state of balance and stability；
But once when the scope of activities of children is excessive so that change the angle position of entire chair frame 2, not by
The resultant force of the chair frame 2 of any power is zero, is standing balance, it is assumed that children have given the power of seat 7 one to the left, and seat 7 is always
It accelerates to the left, at this moment, it is static unbalance, in order to allow it to come back to the state of standing balance, is needed again to seat
7 one sizes of chair are identical, the opposite power in direction, but the two power not only need equal in magnitude, and direction is on the contrary, they are also needed to
On the same line, an object will keep balancing, and it is zero not only to need resultant force, it is also desirable to resultant moment zero, due to balancing pole
13 both ends are separately connected seat 7 and counterweight 1, and seat 7 moves to the left, and corresponding counterweight 1 moves to the right, wherein seat 7,
Balancing pole 13 and the position of centre of gravity of counterweight 1 are fixed axis 5 and are fixed at one, to seat 7 when the rotation of balancing pole 13 and match
1 running torque direction is weighed on the contrary, size is the same, is zero with joint efforts, resultant moment is also zero, so whole equipment remains able to keep
Balance, and the angle of seat 7 is level angle；

Centered on rotate clockwise, allow on the right side of chair and come back on ground, ground can surround the point of rotation to our support force and produce
A raw torque counterclockwise, the clockwise moment generated with gravity balance each other, and power and torque are all balances, if but weight
The heart is displaced to the surface of the point of rotation, and suffered is effectively on same straight line, so torque disappears, this shape
State is difficult to maintain, and when center is continued to when moving to left the left side for changing to the point of rotation, the torque generated at the point of rotation is via suitable
Hour hands become in order to counterclockwise, and clockwise torque balances, and will topple over, since seat 7 is in balancing pole 13 and counterweight 1
Under effect, horizontal angle position is remained, to the meeting vertical drop of seat 7, rather than rollover is toppled over, and in cushion 9
Under buffer protection, children can be sitting on the ground rather than rollover topples over head towards ground, are effectively protected the safety of children.
