Position) after, Mobile base can voluntarily move up under the pulling force effect of spring, be slightly stretched until spring is in
State, the upward power and the restoring force sum of spring that now each strut is put on Mobile base are more than the gravity of Mobile base, with
Tent rack is set to be reliably fitted in open mode.
When tent rack need to be collapsed, press down on deployment rod or pull downward on Mobile base, now the restoring force of spring is (upward
Pulling force) and less, also only need to apply the down thrust of very little or downward pulling force, during Mobile base moves down, although
The restoring force of spring is gradually increasing, but the angle between each strut and spring is also tapering into, the group such as deployment rod and paulin face
The gravity of part produces downward component to Mobile base by each strut and also gradually increased, therefore still needs to be pushed downwards with less
Dynamic, after " dead point " is crossed in the shift position of tent rack, the gravity of the component such as deployment rod and paulin face is made by each strut
Downward force sum for Mobile base has been above the restoring force of spring, i.e., now, Mobile base can be in the presence of each strut
Voluntarily move down, to collapse tent rack, and in the case where tent rack is in rounding state, if being promoted without upward external force, tent
Frame will not opens voluntarily.
