Definitions

  • the object of the invention is a lock casing according to the preamble of Claim 1.
  • the objective of the invention is to create an alternative solution for eliminating the problem described above.
  • a particular objective of the invention is to create a structurally simple and low-cost solution that can also be easily installed in most existing lock casings as necessary.
  • the structure of the lock casing can be kept as simple as possible because the bolt usually has such a pin for controlling the bolt's movement in relation to the lock casing.
  • the end of the protective piece facing the bolt opening has a control edge arranged to steer any tool or similar item inserted through the bolt opening into the lock casing away from the deadlocking means. Furthermore, the end of the protective piece facing the bolt opening is bent towards the bolt body.
  • the protective piece can be advantageously used for covering the transmission and deadlocking means in the lock casing in accordance with the actual structure of the lock casing, preventing the possibility to use various tools.
  • reference number 1 refers to a lock casing that is installed in a cutout made in a door or similar in a way known as such.
  • the lock casing 1 comprises a housing part 1a and a front plate 2.
  • the lock casing 1 has an operating axis 3 on which a key cylinder can be installed on the outside of the door, or a knob or similar actuator can be installed on the inside of the door (not illustrated).
  • a follower 4 is also installed on the operating axis 3 and it is turned using said key cylinder or actuator, and force is transmitted using toothed transmission elements 5 and 7 to a sliding bolt 8.
  • the bolt 8 comprises a bolt end 8a, which in the position illustrated in Figures 1 to 3 protrudes through the bolt opening 2a in the front plate 2 into a bolt opening in the door frame, preventing the door from being turned in relation to the door frame.
  • the bolt 8 also comprises a bolt body 8b located in the housing part of the lock casing 1, which bolt body is fitted with a pin 9 that is guided by the housing part 1 a and correspondingly guides the movements of the bolt 8.
  • the transmission element 7 is pivotably supported on a pin 6 in the lock casing and comprises a control groove 7a that cooperates with the pin 9 on the bolt to move the bolt 8.
  • the control groove 7a has a counter surface 7b which, in the situation illustrated in Figures 1 to 3 , together with the pin 6 provides deadlocking of the bolt, preventing the bolt 8 from being pressed into the lock casing 1, 1a.
  • the protective piece 10 is supported on the pin 9 in the bolt by means of an opening 10c. Thus the protective piece 10 will continuously move with the movement of the bolt 8.
  • the front end 10b of the protective piece is bent and supported directly on the bolt body 8b, and the bend thus created serves as a control edge 10a that steers any tools inserted into the lock casing away from the deadlocking means.
  • the solution according to the invention which prevents manipulation of the bolt, is not dependent on the implementation of force transmission from the operating axis to the bolt and actual deadlocking of the bolt; for example, whether deadlocking is provided by the transmission means that also serve partially as deadlocking means, or whether some separate piece independent from the actual transmission providing the bolt movements is used, because in any case, the basic purpose is to sufficiently cover any elements that could be manipulated, so that they cannot be moved with tools.
  • the solution according to the invention is also independent on whether the lock casing has more than one operating axis.
  • the structure of the protective piece can be simple and thin. Since it can be simply supported on a pin in the bolt that is also used for moving the bolt and providing deadlocking action, the structure of the solution is low-cost and in most cases suitable also for existing lock casings.
