An ecological information carrier with a gravitational unfolding mechanism, and a gravitational unfolding mechanism

摘要

This application involves Ecological information carrier (1) and gravity unfolding mechanism (3), including elasticity display wall and edge join, unfolding mechanism (3) is fastened to the wall of side connection display simultaneously, and it is also equipped with fixed length member and variable-length element, it is characterised in that gravity unfolding mechanism is equipped with gravity expander and variable-length element pass through hinged side expander and which block gravity expander of above-mentioned block element.
