Patent ID: 7685774

Claim:
A closing system for moving a combined sealing system between an unlocked configuration and a locked configuration, the combined sealing system connecting a panel to a frame and including a first sealing system and a second sealing system, each of the first and second sealing systems including an anchor disposed between first and second opposing docking collars and the anchor of the first sealing system substantially perpendicular to the anchor of the second sealing system, comprising: an inner control member connected to one of the first and second docking collars of both the first and second sealing systems; and an outer control member disposed proximate to the inner control member, wherein the outer control member movable relative to the inner control member along a line substantially parallel to a longitudinal axis of one of the control members, and movement of the outer control member relative to the inner control member along the line generates a force against the inner control member towards the anchors when the sealing system moves from the unlocked configuration to the locked configuration, wherein each control member of a proximate pair of the inner and outer control members includes a step that slide relative to each other, increasing or decreasing the distance between the collars.
