Definitions

  • the invention relates to an auxiliary bolt arrangement in a door lock in accordance with the preamble of claim 1.
  • the lock also includes an auxiliary bolt, the purpose of which is to prevent the movement of the latch bolt to its outermost position, while the door is open, and on the other hand, to allow the latch bolt to move to its outermost position urged by its spring after the door has been pressed closed.
  • both the latch bolt and the auxiliary bolt in this lock type are in their protruding positions. If the auxiliary bolt is then inserted into the lock casing by accident or with malicious intention, the latch bolt is simultaneously released to its outermost protruding position thus preventing the pressing of the door closed.
  • the latch bolt becomes deadlocked at the same time and the deadlocking as well needs to be first separately disengaged, for instance by key actuation, before the latch bolt can be moved to its inner position, which enables the closing of the door.
  • a purpose of the invention is to provide a novel and reliable solution with a simplest possible structure for efficient elimination of the above described malfunction.
  • An additional purpose is to make the solution as independent of various other force transmission means acting on the latch bolt as possible so that it may be adapted in as many different kind of lock casing applications as possible.
  • the auxiliary bolt arrangement includes a restraining member, which the auxiliary bolt in its protruding position is arranged to press against the force of a spring to a position, in which the restraining member prevents the movement of the latch bolt to its outermost protruding position.
  • the latch bolt is arranged to retain the restraining member in said position, if solely the auxiliary bolt is being pressed inside the lock casing.
  • the auxiliary bolt and the restraining member have counter surfaces, which are mutually arranged so that the movement of the auxiliary bolt away from the lock casing actuates the movement of the restraining member towards the latch bolt.
  • the auxiliary bolt is provided with a guiding pin, which acts on the restraining member's guide surface, which is bevelled with respect to the direction of the movement.
  • the latch bolt is provided with a shoulder or the like arranged in cooperation with the restraining member.
  • the spring of the latch bolt may preferably be arranged so as to urge the restraining member against the lock casing in order to retain the restraining member in its place.
  • a preferable practical embodiment is provided by arranging the restraining member to move mainly perpendicularly with respect to the movement of the latch bolt and the auxiliary bolt.
  • the reference number 1 refers to a lock casing in a door lock provided with a housing 1 a and a front plate 2.
  • the lock casing also includes a latch bolt 3, which a spring 4 tends to urge out from the lock casing, and an auxiliary bolt 5, which a spring 6 tends to urge out from the lock casing, and a restraining member 9 arranged in conjunction with the latch bolt 5, which a spring 10 tends to move in the direction away from the latch bolt 3, i.e. upwards in the drawings.
  • the lock casing is also provided with at least one operating axis, the force transmission means mounted on which axis can retract, in a manner known as such, the latch bolt 3 against the force of its spring 4 into the lock casing in the purpose of opening the door.
  • the latch bolt 3 has two protruding positions, in the outermost of which it may be deadlocked in a way known as such. Naturally, in that case the retraction of the latch bolt requires also disengagement of deadlocking.
  • Figure 3 illustrates a situation, in which the auxiliary bolt 5 is being pressed inside, while the door is open.
  • the pin 5a of the auxiliary bolt 5 no longer prevents the movement of the restraining member 9.
  • the restraining member 9 stays in a position, in which it prevents the latch bolt 3 from moving to its outermost protruding position. This is due to the fact that the restraining member 9 is, urged by the spring 4 of the latch bolt, between the shoulder 3a of the latch bolt and the inner surface of the lock casing 1.
  • the restraining member 9 holds this position owing to the force of the spring 4 of the latch bolt and friction forces, and the weaker spring 10 acting on the restraining member 9 is not capable of moving the restraining member 9. In this way, the typical malfunction occurring in the former solutions is efficiently eliminated in a simple manner and by minimising the number of required parts.
  • Figure 5 depicts a situation, in which the door is closed as a result of the situation of Figure 4. Since the auxiliary bolt 5 lies against the striker plate and is not allowed to reach the totally protruded position, its pin 5a does not act on the guide surface 9a of the restraining member 9. Thus, the restraining member 9 holds the position according to Figures 4 and 5, whereby it does not prevent the movement of the latch bolt 3, urged by the spring 4, to its outermost protruding position according to Figure 5. When in this situation the aim is to reopen the door, the latch bolt 3 needs to be retracted inside the lock casing by means of the actuators mounted on one of the operating axes.
  • the latch bolt 3 tends to protrude again from the lock casing urged by the spring 4.
  • the auxiliary bolt 5 is urged by the spring 6 to its protruding position shown in Figures 1 and 2. Since the force of the spring 6 of the auxiliary bolt 5 has been chosen so that it overcomes the force of the spring 10 that tends to move the restraining member 9 upwards in the figures, the pin 5a of the auxiliary bolt 5 presses simultaneously, via the guiding surface 9a, the restraining member 9 to the position of Figures 1 and 2, in which it is placed in front of the shoulder 3a of the latch bolt 3 and allows the movement of the latch bolt 3 only to its inner protruding position.
  • the members in cooperation with one another in the solution according to the invention may be shaped in different ways in order to fulfil the desired purpose.
  • the practical application of the invention is suitable for various kinds of lock casings independently of how the latch bolt in each case is retracted into the lock casing or what kind of deadlocking means are possibly in use.
  • the application of the invention does not depend on whether there are possibly other additional bolts in the lock casing, such as a forced deadbolt, or whether e.g. electrical control is used for controlling the operation of the various bolts.
