  • the lock 2 essentially comprises two identical half-housings 29, 30 which contain two identical racks 31, 32, each carrying, on its end head, a bracket, respectively 33, 34; a central pinion 35, indexed by two balls 36, 37 each subjected to the action of a spring 38, 39, respectively, cooperates with the two racks 31, 32; an element 40 secures the pinion 35 and the handle 3.
  • the entire lock 2 is protected by a mask 41.
  • a half-casing 30 consists of a metal part in the general shape of a hollowed rectangular parallelepiped; it has at the center an annular zone 42 comprising a central orifice 43 for guiding the pinion 35.
  • the internal width of the half-housing 30 is a little greater than the diameter of the annular zone 42.
  • the half-housing 30 has two walls longitudinal longitudinal sides, 44, 45, along which are arranged two grooves 46, 47 intended to receive the racks 31, 32 respectively.
  • a flat 48 crossed by a hole 49 a hollow zone 50 having an axial groove 51, an oblong hole 52 and a tab 53 provided at its free end with a notch 54.
  • the flat part 48 receives the body of the rack 31 or 32 when the handle 3 has turned to unlock the leaf 1.
  • the hollow area 50 receives the bracket 33 or 34.
  • the axial groove 51 is provided for the case where the screw for fixing the bracket to the rack head is not completely retracted into the bracket.
  • the oblong hole 52 is intended to allow fixing by screws of a bracket on a rack head.
  • one of the shoulders, 56 is provided with a second hole 60, while the other shoulder 57 is provided with a finger 61.
  • blind holes 62, 63 In the annular zone 42 are blind holes 62, 63, two in number in the example described, but it is sufficient that there is at least one. These blind holes are intended to receive springs 38, 39 respectively, and balls 36, 37, respectively, to index the pinion 35.
  • the pinion 35 is shown in Figures 14 to 16. It has a disc 64 whose dimensions correspond to those of the annular zone 42. The disc 64 has at least one orifice 65, opening or not, intended to cooperate with a ball 36 for index the pinion. Below the disc 64, the pinion 35 has a shaft end 66 intended to pivot in the central orifice 43 of a half-housing, 30, for example. Above the disc 64, the pinion 35 has a toothed crown 67 intended to cooperate with the racks 31 and 32. The toothed crown 67 is extended by a cylindrical surface 68, followed by a second end of the shaft 69 intended to journal in the central orifice 43 of the other half-casing, 29 for example. The axis of the pinion 35 is hollow.
  • each side has on each side a square section orifice, respectively 70 and 71, and in the middle a cylindrical passage 72 of smaller diameter than the side of the square section orifice 70 or 71.
  • Each of the two square section orifices, 70 or 71 is capable of receiving a rod with a corresponding square section, which constitutes the element 40 (also called “square") by means of which the handle 3 can operate the lock 2.
  • the cylindrical passage 72 is intended to let pass a screw 87, the head of which does not cross the passage 72, and which is screwed into the square 40 to maintain it in position in the pinion 35.
  • the pinion 35 At its upper part, at the end of the shaft end 69, the pinion 35 carries two marks 82 intended to be placed in the transverse plane of symmetry of the lock when an orifice 65 of the disc 64 of the pinion 35 is opposite a ball 36. These marks 82 serve for the correct positioning of the racks 31, 32, relative to the pinion 35; in fact, the racks 31, 32 each carry a mark (not shown) intended to be aligned with a mark 82 of the pinion 35 during assembly of the lock.
  • the racks 31 and 32 are identical; only the rack 31 has been shown in Figures 17 and 18.
  • Each rack, such as 31, has a band 73 provided with teeth; these teeth have the height of the toothed crown 67 of the pinion 35. On one side, these teeth are bordered by a bar 74, which consolidates the teeth and allows them to apply a greater force when the handle 3 is operated.
  • the rack has a body 75 widened towards the longitudinal axis of the half-housing 30.
  • the rack body 75 has a head 76 provided with a through hole , tapped or not, 77 intended to receive the screw 78 for fixing a bracket 33.
  • the bracket 33 is constituted by a U-shaped bracket, the two wings of which, provided with a bore 79, frame the head 76 of the rack.
  • the screw 78 for fixing the bracket passes entirely through it and will be fixed in the bore 79 of the opposite wing of the bracket, a bore which is then itself tapped.
  • One of the wings of the bracket 33 is extended by a plate 80, which carries a stud 81 intended to cooperate with a hole in the rod 7 or 8, to ensure the locking or unlocking maneuver of the leaf 1.
  • the mounting of the lock 2 is carried out as follows: in a half-housing, for example 30, the springs 38, 39 are put in place in the blind holes 62, 63; then the balls 36, 37 are placed on the springs 38, 39. The pinion 35 is then put in place, the first end of the shaft 66 coming into the central orifice 43 of the half-housing 30 and the orifices 65 of the disc 64 coming in line with the balls 36, 37.
  • the two racks 31, 32 are then put in place, the bands 73 being inserted in the grooves 46, 47 of the half-housing 30, the bars 74 being placed above the teeth of the ring gear 67 of the pinion 35, the marks carried by the racks being aligned with the pins 82 carried by the pinion 35: the heads 76 of the racks 31, 32 are then in the longitudinal axis of the half-housing 30, each in front of an oblong hole 52.
  • the second half-housing 29 is then put in place to close the lock 2, the fingers 61 of each half-housing 29, 30 penetrating into the holes 60 of the other half-housing 30, 29 respectively to be subsequently crimped there.
  • the brackets 33 are then inserted into the lock 2 through the end openings of the housing (FIG. 13), so that the stirrup of these brackets overlaps the head 76 of the corresponding rack, and the plates 80 are on the side of the half-casing 30, that is to say adjacent to the wall of the leaf 1 when the lock is applied.
  • the fixing screws of the brackets 33 on the rack heads 76 are put in place through the oblong holes 52 of the half-housing 29.
  • the square 40 is inserted in the orifice 71 of the pinion 35 and its fixing screw 87 is put in place through the opposite port 70; the square 40 is thus placed on the side of the housing where the plates 80 of the brackets 33 are not located.
  • this reassembly is carried out by means of the fixing screws 78, at through oblong holes 52 of the half-casing 30.
  • the lock can then be fixed to the leaf by applying to the leaf the half-casing 29 placed upside down relative to the position, which corresponds to a right leaf, and by putting in place the fixing screws as previously indicated.
  • the arrangement obtained is then that of FIG. 1, with a handle which pivots on the side of the hinge of the left leaf to open said leaf.
  • the rods 7 and 8 are then hung on the pins 81 of the brackets 33.
  • the mask 41 is put in place, fixed, for example, by screws in the lateral orifices 86 of one of the half-housings, and the handle 3 is placed on the square 40.
  • the same lock can be used for a right leaf and a left leaf; the construction of the lock requires a minimum of parts: a half-box, a rack, a bracket, a ball, a spring, all these elements intervening in two copies, then a pinion, a square, a mask and a handle. This results in a significant saving, which reduces the cost of the anti-panic equipment of a door with two leaves in a very substantial way, especially as the assembly of the lock according to the invention is simple and rapid.
  • the adaptation of the lock for a right or left leaf is carried out in a simple manner due to the ability to reverse the position of the bracket relative to the rack head, directly from the exterior thanks to the oblong holes and the ability to fix the brackets by screwing from one or other of the sides of the lock due to the presence of the oblong holes on each side of the lock.
