Definitions

  • the invention relates to a protective device with a cylinder lock, the end of the lock cylinder protruding in the installed state on the outside of a door panel covered by a convexly curved protective body provided with a recess and the end face of which is protected by a rotatable protective cover which has a slot for inserting a Key is provided.
  • a large part of the locks used for doors today consist of cylinder locks. These consist essentially of a fixed lock cylinder and a rotatable core mounted in the lock cylinder, the actuation of which can lock and unlock the lock with a key.
  • part of the lock cylinder protrudes from the outside. This cylindrical part is used by burglars to attach a tool, thereby destroying the lock and thereby forcing entry through the door.
  • Such an embodiment is shown in DE Offenlegungsschrift 25 57 151, which also corresponds to the preamble of claim 1.
  • the protective body with the protective cover inserted in it can be used for all cross-sectional shapes of lock cylinders.
  • Such protective covers can of course also be used in cylinder locks in which the latch and the lock cylinder are covered by a metal plate. In this case, the use of a protective body is unnecessary. However, this can be used with all existing and newly assembled cylinder locks that are not integrated in a metal body and therefore protrude from the door panel with their end.
  • This object is achieved according to the invention in that, in order to adapt the position of the protective body and the rotatable protective cover to lock cylinders, the rotatable cores of which are arranged with different eccentricity to the center of the lock cylinder, the recess of the protective body receiving the cylinder end is bushed out with a sleeve, which has a bore arranged eccentrically to the outside diameter of the same. It is thereby achieved that in the case of different eccentricities of the rotatable core, the lock cylinder can be brought into alignment with the rotatable cover by corresponding sleeves.
  • the sleeve is expediently rotatable for such a coaxial alignment of the cores of at least two lock cylinders relative to the protective cover and adjustable in the recess of the protective body in at least two different positions.
  • Further advantageous embodiments of the protective device according to claim 1 are specified in subclaims 3 to 8.
  • the protective body 1 shown in Fig. 1 is shown in a large magnification so that the other parts interacting with the protective body 1 are more visible.
  • the protective body 1 is essentially designed as an oval body which has surfaces inclined on all sides so that a tool attached to it slides off.
  • the protective body 1 has a flat end face 2, in which a passage 3 is arranged.
  • the passage 3 is best seen in FIG. 2, in which the protective body 1 is shown without internal parts.
  • the protective body 1 has on its rear side 4 a recess 5, at the bottom of which the passage 3 connects. As can be seen from FIG. 2, the base of the recess 5 forms a supporting edge 7.
  • a circular cylindrical sleeve 8 is inserted into the recess 5 of the protective body 1, the inner bore 9 of which is arranged eccentrically to the outer diameter 10 of the sleeve 8.
  • the sleeve 8 rests on an edge 12 of the recess 5, but has some play so that it can be rotated or removed and inserted into the recess 5 in a different position.
  • a protective cover 16 is inserted, the shape of which can best be seen from FIG. 3.
  • the protective cover 16 has a cylindrical section 17 and a flange section 18 adjoining it.
  • the flange section 18 is beveled and thus has the shape of a narrow truncated cone.
  • the flange section 18 is supported on the inside of the support edge 7, the cylindrical section 17 on its end face expediently being flush with the flat end face 2 of the support body 1.
  • a slot 20 is provided in the protective cover 2, through which the key of the cylinder lock can be inserted.
  • a protective ring 21 is placed in the recess of the protective body 1. This has a frustoconical passage 22 and lies with it on the truncated cone of the flange section 18. In FIG. 3, the protective ring 21 is shown at a distance from the flange section 18 for a better overview, while in FIG. 1 the protective ring abutting the flange section 18 21 is shown.
  • the protective ring 21 lies in the recess 5 with little play, so that the center axis of its outer diameter is offset according to the offset position of the passage 3 with respect to the recess 5 with respect to the center axis of the frustoconical passage 22.
  • the protective ring 21 has a hole 24 at the location of the greatest material width, which receives a pin 25 which is anchored in the supporting edge 7. This pin 25 is caulked or riveted, so that a firm connection between the protective ring 21 and the support body 1 is created, by which the protective cover 16 is held.
  • the protective ring 21 also forms a drill protection, so that the drill is prevented from penetrating from the flat end face 2 when the support body is drilled out.
  • the support body 1 has two fastening pins 26 which are provided with a threaded blind hole 27. With the mounting pin 26, the protective body 1 is screwed from the inside of the door panel by means of screws.
  • FIG. 4 it can be seen how with two cylinder locks 28, 29, the rotatable cores 30 have different eccentricities e1, e2, through the sleeve 8, which is inserted in two positions offset by 180 ° in the recess 5, in alignment with the center axis 13 of the passage 3 and thus the protective cover 16 can be spent.
  • lock cylinder 28 with a larger eccentricity e1 the thinner wall portion of the sleeve 8 is arranged on the top of the lock cylinder 28, while with the smaller eccentricity e2 of the core 30 in the lock cylinder 29, the larger wall portion of the sleeve 8 is on the top. This is achieved by rotating the sleeve 8 through 180 °.
  • the distances a from the center axis of the core 30 to the edge of the sleeve 8 are of the same size, so that both lock cylinders 28, 29 can be aligned with the protective cover 16 without a change having to be made to the protective body 1.
  • the protective device described thus consists of four parts, the protective body 1, the protective cover 16, the protective ring 21 designed as a drilling protection, and the sleeve 8.
  • the protective body 1 can be expediently cast from an alloy steel casting in an investment casting process together with the pin 25,
  • the protective cover 16 and the protective ring 21 are expediently made of a hardened steel, while the sleeve 8 can be made of a normal structural steel.
  • the fastening pins 26 are expediently produced together with the support body 1.
