Abstract:
1. A multi-point lock installable on an exit door that is mountable on a door frame and is moveable between closed and open positions, said multi-point lock comprising: a. a main lock module comprising a main housing mountable on said exit door, a main lock bolt carried by said main housing and movable between its locked position where it engages said door frame and its unlocked position for allowing said exit door to open, and main drive means on said main housing for moving said main lock bolt between its locked position and its unlocked position, b. a remote lock module comprising a remote housing mountable on said exit door at a location vertically displaced from said main lock module, a remote lock bolt carried by said remote housing and movable between its locked position where it engages said door frame and its unlocked position for allowing said exit door to open, and a remote drive means on said remote housing for moving said remote lock bolt between its locked position and its locked position, c. a push panic bar that is coupled to said main drive means, mountable on said exit door and moveable from its closed to its opened position which activates said main drive means to drive said main lock bolt to its open position, and d. a flexible pull cable having opposite near and remote ends permanently fixed to said main and remote drive means respectively, said cable having pre-determined length such that there will be a corresponding predetermined distance between said main and remote housings when said cable is extended to be generally straight, said main and remote lock modules thus being mountable on said door at a predetermined distance between them without requiring any measurement between them, and e. whereby said push bar, when moved from its closed to its opened position, drives said main drive means to move said main lock bolt to its unlocked position and at the same time, pulls said pull cable whose remote end pulls and thereby drives said remote drive means to move said remote lock bolt to its unlocked position, so that said exit door can be opened.
