  • a catch plate 50 can be moved along a groove 52 so as to, when in a barring position between the arms 44, 48, lock said first and second door handle connections 24, 26, thereby preventing them from being rotated.
  • the catch plate 50 is adapted to be actuated by a lock cylinder (not shown).
  • Fig. 2c illustrates a second embodiment of the lock described hereinbefore with reference to Figs 2a-b. Similar to the lock of Figs 2a-b, the lock 10 of Fig. 2c is provided with a catch plate 50, which is adapted to be actuated by a lock cylinder (not shown) between a barring position and a non- barring position. Fig. 2c illustrates the lock 10 in the locked position, and the catch plate 50 being in a non-barring position. Similar to the lock of Figs 2a-b, the catch 50 plate may be set in its barring position by translating it in the direction indicated with an arrow.
  • the lock 10 is provided with a two-part arm assembly 44a-b.
  • the two-part arm assembly 44a-b comprises an inner arm 44a, which is provided with an inner arm door handle connection 24a that is adapted to be connected to an inner door handle 22a, and an outer arm 44b, which is provided with an outer arm door handle connection 24b that is adapted to be connected to an outer door handle 22b.
  • the inner door handle 22a is arranged to be turned independently of the outer door handle 22b.
  • the catch plate 50 is, when in its barring position, adapted to bar the outer arm 44b, but not the inner arm 44a, from turning. In this manner, when the catch plate 50 is in its barring position, the outer door handle 22b will be barred, such that it can not be operated so as to release the lock 10. At the same time, the inner door handle 22a may be operated so as to turn the inner arm 44a, such that the latch 30 may be released.
  • both door handles 22a-b may be operated so as to release the latch 30.
  • An outer arm dog 56b is adapted to, upon turning of the outer door handle 22b, abut against and drive the inner arm 44a, such that the inner arm 44a will follow the motion of the outer arm 44b when the outer door handle 22b is turned.
  • This design allows the release plate 42 to be operated in the same manner irrespective of whether the inner door handle 22a or the outer door handle 22b is used for unlocking the lock 10.
  • a dog 56a may also be present on the inner arm 44a.
  • the inner arm door handle connection 24a may be made larger than the outer arm door handle connection 24b, such that any object inserted through the outer arm door handle connection 24b will need to be too small to engage with the inner arm door handle connection 24a.
  • the inner arm 44a may be made tamper-proof by inserting a washer, blocking the passage, between the inner and outer arm door handle connections 24a-b.
  • first two-part arm assembly 44a-b has been described.
  • the lock 10 is also provided with a second two-part arm assembly 48a-b, to which the above description with reference to the first two-part arm assembly 44a-b also applies, mutatis mutandis.
