<p>PCT No. PCT/GB94/01601 Sec. 371 Date Jan. 19, 1996 Sec. 102(e) Date Jan. 19, 1996 PCT Filed Jul. 26, 1994 PCT Pub. No. WO95/03463 PCT Pub. Date Feb. 2, 1995A shoot bolt mechanism includes a casing having a front wall and a rear wall. The casing contains a shoot bolt having opposed ends and slidable between an inoperative and an operative position. A rotatable drive member is mounted in the casing adjacent the casing rear wall. A link is pivotally connected at one end to the shoot bolt and at another end to the drive member at a point eccentric from an axis of rotation of the drive member. Rotation of the drive member is translated by the link into movement of the shoot bolt between retracted and extended positions. Two drive transfer members are disposed on respective opposite sides of the shoot bolt between opposed ends thereof when the shoot bolt is in the retracted position. Rotation of the drive member moves the drive transfer members between respective retracted and extended positions in directions generally normal to the direction of movement of the shoot bolt between its retracted and extended positions.</p> |
