Definitions

  • the present invention relates to a device for locking the bolts actuated by the strike lock in a two-wing emergency door as set out in the first part of claim 1.
  • both wings open outwardly and the wing normally used to enter and exit (hereinafter termed wing A) is provided with a panic-safe lock which is designed so that the latch and the bolt can be moved simultaneously into the release position by operating the handle.
  • the other wing (hereinafter termed wing B) acts as a rabbet for wing A and is provided with an upper and a lower bolts which are vertically slideable and connected, by means of rods, to a so-called panic-safe actuation strike lock that can be operated by means of an appropriate handle.
  • GB-A-383 359 discloses a bolt locking device including a combination of elements as recited in the preamble of the appended claim 1, including in particular a pivoting catch piece arranged to engage with an abutment of a pivoting bolt head to retain the bolt head in an inward position.
  • the catch piece is released by a spring-biased plunger projecting from the face of the door edge to engage with the door frame.
  • the plunger is provided with an inclined slot with which engages a projection of the catch piece.
  • US-A-2 908 523 discloses a pivoting latch bolt disposed adjacent a spring-biased slide member for retaining the latch bolt in a retracted position.
  • the slide member includes an inclined camming face for engaging a strike of a door for sliding the slide member.
  • the latch bolt is provided with a pin or roller which engages with a shoulder of an abutment of the slide member, when the latch bolt is in a projecting position, so as to retain the slide member in a retracted position.
  • the slide member When the latch bolt is pivotally released into its retracted position, the slide member is released into a projecting position, and an abutment surface of the abutment of the slide member engages with the roller or pin of the latch bolt to retain the latch bolt in its retracted position, until the slide member engages the strike of the door whereupon the roller or pin is released for returning the latch bolt into its projecting position.
  • the principal aim of the present invention is therefore to provide a device of the initially mentioned type which can obviate the shortcomings that can be noted in the known art.
  • the device comprises a casing 1 which is composed of a substantially cylindrical cup 2 having respective plane-parallel regions 3 and 4 in opposite positions.
  • the cup 2 has a bottom 5 and, at the end opposite to the bottom 5, a flange 6 to which a quadrangular plate 7 is coupled.
  • Countersunk holes 8 for the passage of the screws by means of which the device is fixed to the wing of the door are formed at the corners of the plate 7 and of the flange 6. More specifically, the device is inserted in a cylindrical cavity 9 which is open on the upper edge 10 of the wing, so that the flat regions 3 and 4 are at right angles to the plane of said wing.
  • a hole 11 is formed in the bottom 5 and eccentrically with respect to the axis A of the cup; the bolt 12 is driven through said hole and engages in the lintel of the walled frame to lock the door in closed position.
  • the bolt 12 is constituted by a cylindrical rod which is actuated by the strike lock in a manner that is beyond the scope of the present invention.
  • the hole 11 through which the bolt passes is internally tangent to the cup 2, so that the bolt is in tangential contact with the inner wall of the cup along a line 13 which lies in the intermediate centerline plane P which is plane-parallel with respect to the flat regions 3 and 4.
  • the bolt 12 is actuated upwards by a spring, not shown, and is operatively associated with a lower bolt, also not shown, so that the actuation of the bolts occurs simultaneously.
  • the eccentric position of the bolt 12 allows to place a mechanical sensor 14 between said position and the wall of the cup which lies opposite to the contact point 13; said sensor 14 has the purpose of detecting the closed or open position of the door and consequently releasing or locking the bolt.
  • Said sensor 14 is constituted by an element having a substantially U-shaped cross-section which forms, by means of two wings 15 and 16, a semicylindrical channel 17 inside which the bolt 12 is guided.
  • the wings 15 and 16 are connected by a thicker portion 18 in which there is a hole 19 which lies at right angles to the axis A of the cup and is ovalized so as to intersect the channel 17.
  • a pin 20 is inserted in the hole 19, and its opposite ends engage in slots 21 and 22 formed in the flat regions 3 and 4 of the cup.
  • the slots 21 and 22 comprise a lower portion 23 which is parallel to the axis A of the cup and an upper portion 24 which is inclined so that by making the sensor 14 slide in the cup 2 the pin 20 moves transversely in the hole 19.
  • the end of the sensor 14 protruding from the cup 2 has a chamfer 25 which affects not only the portion 18 but also the wings 15 and 16 so as to form a sort of latch suitable to retract when the sensor strikes the lintel of the walled frame of the door.
  • the described device is completed by a spring 26 which acts by compression, is interposed between the bottom 5 and the sensor 14, and is partially accommodated in a recess 27 of the portion 18.
  • Figures 2 and 3 illustrate the device in the condition in which the door is open, i.e. with the bolt 12 in retracted position.
  • the lower bolt not shown, is in retracted position as well. Due to the action of the spring 26, the sensor 14 is pushed upwardly so that the pin 20, by following the profile of the slots 21 and 22, is moved laterally in the ovalized hole 19 and is forced against the bolt 12, which is thus locked in retracted position.
  • the sensor 14 due to the abutment of the chamfer 25 against the lintel 28 of the door, is pushed so that it retracts into the cup 2, so as to space the pin 20 from the bolt 12 by means of the slots 21 and 22, thus allowing said bolt to engage the selvage 29 of the lintel by virtue of the action of the spring which pushes it upwards.
  • the lower bolt also engages the selvage of the floor.
  • the invention perfectly achieves the intended aim.
  • the device is easy to install and that by virtue of the chamfer 25 it can compensate for any differences in level between the lintel 28 and the upper edge 10 of the door wing.
  • a bracket 30 is rigidly coupled to the cup 2, extends downwardly, and supports a ring 31 which surrounds the bolt.
  • a spring 33 is interposed between the ring 31 and a shoulder 32 of the bolt and expels the bolt when the sensor 14 abuts against the lintel 28.
