Definitions

  • the invention relates to a mechanical locking device that can be used for closing wagons, containers, warehouses, apartments, garages, etc.
  • Such a locking device is known from US-A-1 527 336, which has a housing, a bolt and a key with code pins. A main room and additional rooms connected to it are provided in the housing. The longitudinal axis of each adjoining room is perpendicular to the longitudinal axis of the main room.
  • a bow-shaped latch is arranged to be longitudinally displaceable in the housing and has an insertion head which can be inserted into the main space and into which recesses are incorporated.
  • a code fixer is arranged to be longitudinally displaceable, which has a code recess on the side surface.
  • the longitudinal shift of the code fixers takes place by springs, which lie between the floor of the adjoining room and the face of the code fixator.
  • the longitudinal displacement of the code fixers towards the surface of the housing is limited by pins which are fastened in the housing and arranged in through grooves in the code fixers.
  • the cross-sectional profile of each recess on the side face of the code fixator corresponds to the profile of the recesses on the insertion head for locking it in the housing.
  • the code pins of the key are rigidly attached to a support plate and perpendicular to its surface. The number of code pins matches the number of code fixers.
  • the known code unit enables the object to be blocked with a certain level of security.
  • this blocking device can be opened without permission by scanning the positions of the recesses on the code fixers.
  • the pins for limiting the longitudinal displacement of the code fixators can be sheared off by striking the code fixer. Due to the bow shape of the bolt, the locking device can be blasted off the object to be locked using a lever or by the action of blows.
  • the bolt rigidly fixed in the housing can be sawed through, which also reduces the level of security.
  • the invention has for its object to provide a locking device that ensures a high level of security and minimizes the possibility of unauthorized (unauthorized) removal by mechanical influences.
  • the locking device which has a housing in which a main cavity and associated secondary cavities connected thereto, the longitudinal axis of each secondary space being perpendicular to the longitudinal axis of the main space, a removable latch with an insert head which is suitable for the accommodation in the main cavity of the housing and for the interaction with code fixers, each of which is arranged with the possibility of a limited longitudinal displacement in an associated additional cavity and has a code recess on the end face, and a key intended for interaction with the code fixers Contains code pins that ensure an unobstructed exit of the plug-in head from the housing by arranging all code recesses in a plane that runs through the longitudinal axis of the plug-in head, at least one longitudinal rib being formed on the side face of the plug-in head t, whose cross-sectional profile corresponds to that of the code depressions, in which the depth corresponds to the height of the longitudinal rib and each code fixer has at least one additional recess, whose cross-sectional profile corresponds to that
  • each code fixer is moved in an additional cavity by gravitational forces.
  • annular recesses are made on the side face of the insertion head, which interact with the code fixers and whose cross-sectional profile corresponds to the profile of the code fixers in cross-section.
  • the cross-sectional area of the insertion head is expediently smaller than the cross-sectional area of the bolt.
  • a cover can be rigidly attached to the housing with through holes provided for receiving code pins, each of which is connected to the associated adjoining room and has a cross-sectional area that is smaller than the cross-sectional area of the adjoining room.
  • code pins each of which is connected to the associated adjoining room and has a cross-sectional area that is smaller than the cross-sectional area of the adjoining room.
  • the housing is used to limit the longitudinal displacement of the code fixers in the Adjacent rooms in a box, certain through holes being made in the housing for accommodating code pins, each of which is connected to the associated adjoining room and has a cross-sectional area that is smaller than the cross-sectional area of the additional cavity.
  • the axis of each through hole should be offset with respect to the longitudinal axis of the associated adjoining room in order to make it difficult to remove the code fixers from the housing by drilling out.
  • the code pins of the key can be attached to a support element with the possibility of an angular rotation about this.
  • the code pins can also be arranged in a longitudinally adjustable manner on a supporting element, which enables the production of keys with erasable or adjustable coding and precludes the unauthorized opening of the locking device without knowledge of the code.
  • the correct code can also be transmitted to an authorized person without sending the key.
  • a through hole is made in the front end of the plug-in head outside the housing for receiving the seal.
  • the locking device shown contains a housing 1 (Fig. 1) z. B. has the shape of a cylinder, and a removable cylindrical latch 2. According to FIG. 2, a partially cylindrical central main space 3 (FIG. 2) and six side rooms 4 connected to it are provided in the housing 1.
  • the bolt has an insertion head 5, which is introduced into the main room 3 and together with code fixers 6, which are individually arranged to be longitudinally displaceable to a limited extent in an adjacent room 4.
  • code fixers 6 in the adjoining rooms 4 are moved by gravity.
  • At least one longitudinal rib 7 is formed on at least one side surface of the insertion head 5, the embodiment shown having a longitudinal rib 7 on each side surface (FIG. 4).
  • a code recess in the form of an annular groove 8 is implemented on each code fixer 6 (FIG. 5), the cross-sectional profile of which corresponds to that of the longitudinal rib 7.
  • At least one additional annular groove 9 is implemented on each code fixer 6, the embodiment shown having four annular grooves 9.
  • the width of the additional annular grooves 9 corresponds to the width or shape of the longitudinal rib 7, while the depth of this groove 9 is smaller than the height of the rib 7.
  • a cover 10 is permanently attached to the housing 1, e.g. B. welded. Through holes 11 are made in the cover 10, which are connected to the associated adjoining room 4 and have a smaller cross-sectional area than the respective cross-sectional area of the adjoining rooms 4.
  • the axis of each through hole 11 in the cover 10 is offset with respect to the longitudinal axis of the associated adjoining room 4.
  • annular grooves 12 are incorporated on the cylindrical insertion head, which with the Code fixers 6 cooperate and their shape corresponds to the profile of the code fixers in cross section. These annular grooves 12 enable the cylindrical bolt 2 to rotate freely about the longitudinal axis in the main space 3 of the housing 1.
  • the key essentially consists of a plate on which code pins 13 are fastened upright, which are inserted into the through holes 11 and interact with the associated code fixers 6 (cf. FIG. 2).
  • the key can have different designs.
  • a key is used to lock means of transport (such as wagons or containers), the code pins 14 of which are attached to a support element 15 in a longitudinally adjustable manner according to FIG. 7.
  • Each code pin 14 has markings 16 for setting the unlocking position. This key design allows the keys to be sent when the code is transmitted separately and enables the selected unlocking code to be deleted, which makes it impossible to open the lock without permission.
  • the key according to FIG. 8 can have code pins 17 which are pivotably articulated on a support element 18.
  • the length of each code pin 17 corresponds to the code. This key offers ease of use and is very compact when the code pins 17 are folded.
  • the key is inserted into the cover holes 11 with the code pins 13 (FIG. 6). All code fixers 6 are brought into a position according to FIG. 2, in which the code depressions 8 of all fixators 6 are located in one plane and allow the ribs 7 of the insertion head 5 to pass freely. Then the latch 2 is inserted into the housing 1 until it stops. After removal of the key, the code fixers 6 fall down due to their own weight and lock the bolt 2, whereby they are located in the annular incisions 12 of the insertion head 5. The latch 2 is released by inserting the key again.
  • the code unit described can be used both in mobile and in stationary blocking devices.
  • a box-shaped component (not shown) serves to limit the longitudinal displacement of the code fixers 6 in the housing 1.
  • the bores for receiving the code pins 13 of the key in the housing 1 are formed at the bottom.
  • the code recesses on the transverse in the housing 26 against the force of springs 27 movable code fixers 19 are formed as a cutout 20 and the additional recesses as blind grooves 21.
  • the bolt 22 shown in FIG. 11 is rectangular and has a longitudinal rib 24 on its insertion head 23, which is subdivided by slots 25 for receiving the code fixers 19.
  • the code fixers 19 are held in the rectangular housing 26 according to FIG. 12 by the springs 27 in the position shown.
  • the locking device is closed and opened, as in the embodiments described above, by pulling out or inserting the code pins of a key 28 shown in FIG. 13.
  • the main room 3 is formed continuously and the insertion head 5 is pushed through the housing 1 (cf. FIG. 14).
  • a transverse bore 29 is formed through which the band of a seal 30 is pulled.
  • the locking device has a simple design and does not require high manufacturing accuracy.
  • the code unit increases the security against locking considerably and it is practically impossible to use a lock key or duplicate key. Unauthorized opening of the locking device cannot be carried out either by successively selecting code variants or by scanning. In addition, the strength is increased and an unauthorized removal of the lock from the object to be locked with the help of heavy tools such as sledgehammers, crowbars, hacksaws and the like.
  • the proposed code unit is user-friendly and requires no repair in the mobile version. Repair work on built-in locks can be carried out easily.
