Abstract
A latching system includes a rotatable cam formed of substantially symmetric pieces with a cable, connected to oppositely disposed bolts, extending therethrough. The configuration of the cam is such that when rotated, the cable is pulled in both directions with respect to each of the bolts, allowing for the bolts to move so as to disengage from their respective strikers, unlatching the system.
Claims19
A roll up door system comprising:
- a door including at least one panel;
- a first latch member and a second latch member movably mounted on said at least one panel for movement between inward and outward positions;
- a cable in communication with said first latch member and said second latch member;
- and,
- a cam member for displacing said cable to move said first and second latch members, said cam member including, a first portion including a first flat portion, and a second portion including a second flat portion, said first and second portions being disposed with respect to each other so the first flat portion and the second flat portion define a substantially straight slot configured for receiving an at least substantially straight portion of said cable, wherein the first portion forms a first outwardly curved edge and the second portion forms a second outwardly curved edge, wherein the first curved edge and the second curved edge are positioned at opposite ends of the substantially straight slot.
