Definitions

  • the present invention relates to a device for facilitating the opening of two-leaf safety doors.
  • leaf A In safety doors of the indicated type, both leaves open outwards, and the one which is normally used to enter and exit (hereinafter termed as leaf A) has an antipanic lock, provided with a spring latch and a bolt, designed so that the spring latch and the bolt can be moved simultaneously into release position by actuating the handle.
  • leaf B acts as wing for leaf A and is provided with an upper and a lower bolts which are connected, by means of rods, to a so-called antipanic actuation strike lock actuatable by means of its own handle.
  • safety doors of the indicated type is that the spring latch and the bolt of the lock installed on leaf A engage seats of the strike lock of leaf B, the mechanism of which is preset so that if only the lock of leaf A is actuated in order to open, thus retracting the spring latch and the bolt, only leaf A can be opened, since the strike lock keeps its bolts in locking position.
  • the technical aim of the present invention is to correct the movement of the element of the strike lock of leaf B which opens the lock of leaf A, so as to obviate the above described drawback.
  • the reference numeral 1 designates a generic strike lock the constructive details whereof are not described since they are not pertinent to the present invention.
  • the strike lock comprises a casing 2 coupled to a faceplate 3 and provided with two parallel walls 4 and 5 which are normal to the faceplate 3.
  • openings for the engagement of the spring latch and of the bolt of the lock, and a further opening 6, are defined in the faceplate 3; the element 7 meant to act on the lock to release it in emergencies is guided outside through said opening 6.
  • the element 7 comprises a cylindrical tang 8 frontally provided with a pad 9 and, in a rear region, with a fork 10 resting on the wall 4.
  • the fork 10 slidably engages a bush 11 fixed between the walls 4 and 5 and aligned with the tang 8.
  • a connecting rod 12 is rotatably supported on the bush 11 and constitutes one side of an articulated parallelogram; the other side is constituted by a lever 13 which is radially fixed to the hub 14 of the handle.
  • the hub 14 can turn between the walls 4 and 5 and is provided with a square hole 15 for the side-fitting engagement of the pivot of the handle.
  • the connecting rod 12 and the lever 13 are articulatedly connected by a triangular link 16 having a wing 17 along one edge; said wing engages the tang.
  • the arm R1 of the lever 13 is longer than the arm R2 of the connecting rod 12, and the wing 17 is inclined with respect to the line R3 which connects the articulation points of the link 16 in the connecting rod 12 and in the lever 13.
  • the line R3 which connects the articulation points of the link to the connecting rod 12 and to the lever 13 is at right angles to the axis C of the tang, and the wing 17 forms an acute angle with said axis (see figure 1).
  • the link 16 By actuating the handle, i.e. by turning the hub 14 clockwise, the link 16, being connected to the connected rod 12 and to the lever 13, moves toward the faceplate 3 and, due to the greater length of the arm R1 of the lever 13 with respect to the arm R2 of the connecting rod 12, it tilts so that the wing 17 is increasingly perpendicular to the axis C of the tang.
  • the wing 17 acts on the tang 8 which, once it has reached its maximum outward stroke, acts on the mechanism of the oppositely arranged lock, opening it.
  • the maximum outward stroke of the tang 8 coincides with the position of the wing 17 which is perpendicular to the axis C of the tang 8 (position A of figure 2).
  • the link 116 is provided with an expansion 18 extending downwards and in which a slot 19 is defined; the slot is V-shaped and its vertex is directed toward the faceplate 103.
  • the element 107 is arranged between the expansion 18 and the wall 104; it comprises a prism-shaped block 20 the upper and lower faces whereof are parallel and perpendicular to the faceplate 103. Grooves 21 and 22 are defined in these faces and are engaged by the oppositely arranged wings 23 and 24 of a guide 25 which is C-shaped and is fixed to the wall 104; said guide allows the block 20 to slide at right angles to the faceplate 103.
  • the block 20 is crossed by a threaded hole 26 which is parallel to its sliding direction and continues with a smooth hole 27.
  • a screw 28 is screwed in the threaded hole 26 and has a stem 29 rotatably inserted in a ring 30 which is guided in the hole 27.
  • the ring 30 is retained axially on the stem by an elastic washer 31 and has a pivot 32 protruding laterally from the block 20 through an axial slot (not shown in the drawing) to engage in the slot 19.
  • actuation of the handle moves the block 20 toward the faceplate 103; the block 20 can thus act, through an opening 33 of the faceplate 103, on the oppositely arranged lock to actuate it.
  • the opening 33 of the illustrated example has such dimensions as to also allow the engagement of the bolt so that, in the leaf closure position, the block 20 and the bolt are arranged on top of one another.
  • a friction ring 34 acts on the screw 28 and prevents its unintentional rotation.
