发明名称 Storm curtain with counterbalance system and drive component protection
摘要 A storm curtain assembly ( 10 ) includes a fabric curtain ( 11 ) which may be wound onto a roll ( 17 ) and stored within a canister housing ( 16 ) when not in use, and substantially unwound from the roll ( 17 ) to cover an opening in a building. When unwound, a lock bar ( 18 ) is engaged by the hooks ( 27 ) of the lock blocks ( 21 ) carried by the housing ( 16 ) and by lock tabs ( 22 ) carried by the housing ( 16 ). The lock tabs ( 22 ) extend through slots ( 28 ) formed in curtain ( 11 ) so as to be able to engage the lock bar ( 18 ). As such, the roll ( 17 ) and other drive or counterbalance components ( 15 ) carried in the housing ( 16 ) are protected from any forces on the curtain ( 11 ), such forces being absorbed by the housing ( 16 ).
