Definitions
- the present invention relates to a device lock for the semi-fixed leaf of a fire door or analogous, with two leaves.
- fire doors are generally ordered automatically when closing by electronic means connected to a fire detector.
- the two leaves, held open by suction cups electromagnetic, are then closed one after the other.
- This goal is achieved by equipping one of the leaves, the one that closes first and which is called a leaf semi-fixed, at each of the two corners opposite to those on the side of which is articulated, a lock having a share a first movable bolt moving in the direction vertical and likely to engage in a strike practiced, either in the ground or in the part transverse frame, depending on whether said lock is placed in the bottom corner or the top corner of the leaf respectively; and on the other hand a second bolt movable horizontally projecting laterally from said leaf, the retraction of said second bolt, caused by the closing of the second leaf, commanding the exit of the first bolt.
- top, bottom, vertical and horizontal are used with reference to an observer looking at the locking device according to the invention and standing in face of the leaf which is fitted with it.
- the object of the present invention is to remedy this drawback by proposing a lock device for simple design that can be integrated into doors that are of standard thickness.
- the locking device object of this invention is essentially characterized in that the two bolts are linked in movement by a gear wheel which meshes with two racks, each secured by a said bolts, said horizontal bolt being recalled at the outlet by a spring.
- the horizontal bolt is guided moving through a rod passing through it by an oblong light practiced in it.
- the bolt rack vertical has a longitudinal slot through which passes the part of the horizontal bolt comprising the rack.
- a lock device comprises of share a bolt 1 secured to the end of a plate 10 having at its upper edge a rack 11; else share a bolt 2, one longitudinal edge of which has a rack 20; and on the other hand still a gear 3 which meshes with the racks 11 and 20.
- the lock device comprises a headrest 4 comprising two parts 40 and 41, making between them a right angle and united on the song of a semi-fixed leaf 5, in a corner thereof, part 40 horizontal being crossed perpendicularly by the bolt 2, while the vertical part 41 is crossed by the bolt 1.
- the lock device also includes a plate 42, parallel to the plane of the semi-fixed leaf 5, integral with the headrest 4, and on which are subject on the one hand to a pivot 43 on which is mounted in free rotation the toothed wheel 3; on the other hand a rod 44 transversely crossing an oblong lumen 12 practiced in the plate 10 parallel to the rack 11; on the other hand still guide pads 45 bolt 2; and on the other hand, a repelling spring 46 the bolt 2 at the outlet.
- the bolt 1 is movable horizontally, its movement is guided and limited by the oblong light 12 and the rod 44, and it rotates the toothed wheel 3 via the rack 11, while the rotation of the toothed wheel 3 causes the bolt to move 2.
- the bolt 2 has a slot at the rack 20 longitudinal 21 cutting the latter into two parts, and in which is engaged the plate 10 which is guided therein the transverse direction.
- the vertical edge 70 of the movable leaf 7 exerts pressure on the bolt 1, so that it moves in reentry, thus causing, via the wheel tooth 3, the exit of the bolt 2 and the engagement of this one in a keeper 60 made in the frame 6.
- the bolt 1 has and in a manner known per se, a beveled part 13, visible on Figure 1, facilitating its reentry when closing the movable leaf 7.
- the movable leaf 7 being equipped with a lock of the conventional type, not shown, and the semi-fixed leaf 5 of a keeper, also not shown, the two leaves 5 and 7 are then linked to each other and to frame 6, the opening of the movable leaf 7 triggering the unlocking of the leaf semi-fixed 5.
