Definitions

  • the invention relates to a cylinder lock, consisting of an outer cylinder with two longitudinal recesses offset by 180 °, with an inner cylinder rotatably arranged in the outer cylinder, with at least two plate-shaped tumblers movable in guide slots of the inner cylinder, the length of the tumblers corresponding to the diameter of the inner cylinder, in Engage the locked state in a longitudinal groove of the outer cylinder and thereby block the inner cylinder against twisting, are provided with windows for a key and move out of the area of the longitudinal groove into the open position when the corresponding key is inserted and the inner cylinder is thereby rotatable.
  • a cylinder lock which works with tumblers that dip into the blocking channel to different degrees, is known (DE-OS 28 15 380).
  • the tumblers are spring-loaded here and are limited in their movement by side stops on the tumblers in the direction of the spring action, ie downwards towards the locking channel. In the other direction, the movement is limited by end stops on the outer cylinder and a corresponding shape of the tumblers. Due to the different immersion depths of the tumbler plates in the blocking channel it is prevented that the tumbler plates can be lifted into the unlocking position simultaneously and together by an object inserted into the key window.
  • the well-known cylinder lock is complex to manufacture and difficult to assemble.
  • the inner cylinder must be pushed in as far as the first guide slot for the first tumbler, the spring inserted, the tumbler inserted from below and then the inner cylinder must be pushed a bit into the outer cylinder with the tumbler spring tensioned.
  • the approach of the guard locking is then rubbed against the outer cylinder. So every tumbler must be introduced against the force of the preloaded springs.
  • the object of the invention is therefore to provide a cylinder lock with plate-shaped tumblers, which has a high locking security, which is simple in construction, inexpensive to manufacture and simple and inexpensive to assemble.
  • the invention solves this problem and creates a cylinder lock of the type described above, in which the new consists in that the tumbler plates have lugs on their side flanks, that recesses are made in the inner cylinder, extending in the longitudinal direction of the guide slots, into which the lugs of the tumbler plates engage and the tumbler plates are limited in their movement by the width of the lugs, that the tumbler plates are freely movable in the guide slots of the inner cylinder without spring force and that the inner cylinder consists of two parts, the dividing line running in the longitudinal direction.
  • this new cylinder lock does not contain any springs and is therefore simple in construction and inexpensive to manufacture. Due to the divided inner cylinder, the recesses can be made inexpensively in terms of production technology. Due to the divisible inner cylinder, the tumblers can be easily inserted into their guide slots during assembly. The inner cylinder can thus be completely pre-assembled with the tumblers.
  • Another feature of the invention is that the two parts of the inner cylinder are held together by pins and the dividing line runs in the region of the recesses. Since the lock according to the invention has no springs, there is also no difficulty in mounting against prestressed springs. This simple installation option is particularly advantageous for cylinder locks that are mass-produced in large quantities.
  • the invention also provides that tumblers with shoulders and tumblers with notches and / or known tumblers with continuous longitudinal edges are contained in the lock. This also makes unauthorized opening impossible.
  • a cylinder lock in which an outer cylinder 1 is inserted non-rotatably in a cylinder housing 3.
  • tumbler plates 7 without springs are each loosely arranged in pairs and are freely displaceable radially in the longitudinal direction relative to the inner cylinder 5.
  • the outer cylinder 1 is provided with two diametrically opposed longitudinal grooves 9, the width of which corresponds to the width of the tumbler plates 7.
  • the tumbler plates each have a window-like opening 11 through which the key 13 is inserted when it is inserted into the lock.
  • These windows 11 are designed so that they cooperate with the two profiled longitudinal edges of the key 13 such that when the key 13 has been fully inserted into the lock, the tumbler plates 7 are in their central position, that is, inevitably displaced by the key inserted and have been arranged in relation to the parting line between the inner and outer cylinders 5, 1 in such a way that the inner cylinder 5 has thereby become freely rotatable. 1 shows this state of the lock.
  • Fig. 2 is the storage of a tumbler plate 7 in its guide slot 15 when the key is not inserted, i.e. shown in the locked state.
  • Recesses 17 of length X are made on inner cylinder 5, into which lugs 19 of tumbler plate 7 with length Y engage.
  • the lugs 19 end at a distance Z from the broad side of the tumbler plate 7.
  • the arrangement has the following function: by appropriate selection of the distance Z on each tumbler plate 7 of the lock it is achieved that at least one of the tumblers 7 of the lock comes to rest in the locked state at a distance 21 from the bottom of the longitudinal groove 9. A further tumbler plate 7 could be in the locked state at the bottom of the longitudinal groove 9 by the choice of the distance Z (see FIG. 3).
  • the plate shown protrudes into the upper longitudinal groove (dashed line 23) and lock the lock again.
  • the lengths X and Y are to be dimensioned such that, in coordination with the windows 11, the tumbler plates 7 can be brought into their central position when the key is inserted.
  • the inner cylinder 3 shows a tumbler plate 7 which has notches 25 on its long side. These notches 25 come to lie in the locked state opposite hooking edges 27 of the outer cylinder 1.
  • the inner cylinder 3 consists of two parts 3a, 3b, which are held together by pins 29.
