Definitions

  • the invention relates to a locking system for a housing according to the preamble of claim 1, for example a locking system for a receiving housing for a money safe in a telephone column, with at least one locking lug, which in the closed state of the housing door engages with a locking element arranged in the housing.
  • Such locking systems for securing housing doors can be found on housings of all kinds. Particular requirements for the security of such locking systems apply, for example, in the case of money safes of coin-operated devices, such as Phone columns. Experience has shown that the housing doors of housings which contain such money safes are frequently exposed to vandalism and in particular attempts to break open. This is all the more true since the coin-operated devices mentioned are frequently accessible to the public and the corresponding housings can therefore be easily broken open in the event of an inadequate locking system.
  • a known locking system for housing doors is designed as follows.
  • a guide element is arranged in the housing door, in which one or more locking rods are mounted.
  • the locking rod is in turn actuated by a driver, which converts a rotation of a key into a linear movement of the locking rod, and the locking rod has a locking lug, which in the closed state of the housing door reaches behind a locking element or striking plate in the housing (see FIGS. 6 and 7).
  • a second known locking system (see FIGS. 8 and 9) has a similar structure. In contrast to the first known
  • the locking lug is not on the locking rod here, but on the locking plate, and the locking rod has a spike for this purpose, which engages with the locking lug of the locking plate when the housing door is closed (see Figs. 8 and 9).
  • a housing door with one of these two known locking systems can, however, be broken open in a very short time, since when the housing door is pried open - for example by inserting a lever between
  • Housing door and housing - the locking lug bends slightly. This means that the locking lug and locking element disengage and the door can be opened.
  • the invention is therefore based on the object of creating an improved locking system for housing doors.
  • a securing element is provided in the vicinity of the locking lug, at least on the side of the locking lug facing away from the opening direction, which secures the locking lug against bending in the closed state.
  • the locking lug In the event of an attempt to break open, the locking lug will bend a bit against the opening direction of the door, but only until the locking lug hits the securing element. The securing element then prevents further bending and thus the opening of the door.
  • the closing direction can be provided both in the direction from top to bottom and from bottom to top. In other words, the locking lug can be used for a movement from top to bottom and for another
  • the securing element can advantageously be part of a guide element which is connected to the housing door and in which a locking rod is mounted.
  • the locking lug then engages in the locking element and in the securing element of the guide element and is thus secured against bending.
  • one or more guide elements can be provided and that the securing element is accordingly part of the respective guide element.
  • the locking lug can be part of the locking rod. This reduces the number of individual parts and thus the manufacturing and assembly costs.
  • a locking rod has a plurality of locking lugs. Accordingly, there are several locking elements in the housing intended. This has the advantage that the housing can be closed at several points with the movement of a single locking rod.
  • the closing linkage has a predetermined breaking point, preferably in an area running parallel to the closing nose.
  • the locking linkage tears at the predetermined breaking point, but the locking lug remains in place or is even pulled further into the securing element. The door can therefore not be opened or only a little bit.
  • the guide element preferably has a recess which engages around the closing element in the closed state. In this way it can be ensured in a structurally simple manner that the locking lug engages in the sealing element preferably arranged in the guide element and in this case is secured as a securing element by the edge of the recess in the guide element.
  • the locking lug engages in the closed element through an opening - for example an elongated hole - in the locking element, the locking lug is already secured against bending by the locking element, in particular if the opening is not significantly larger than the locking lug.
  • the closing element can therefore simultaneously serve as a securing element.
  • the guide element of which, as mentioned, there may be several, also has an opening which forms the securing element.
  • the housing door can be secured at two points, for example on its top and on its underside, and it is not possible to bend the housing door a little way at a point remote from the locking connection.
  • connection between the driver and the locking linkage also represents a weak point, because this connection is very close to the door gap and is already open when the door is slightly open with tools, e.g. with a "screwdriver.
  • the connection between the driver and the locking rod is therefore designed to be non-detachable in an advantageous embodiment of the invention.
  • This configuration of the connection between the driver and the locking rod is a separate feature of the present invention, which is completely independent of the Design of the securing element is.
  • FIG. 1 Show in detail: 1 a locking system according to the invention (open), FIG. 2 the locking system according to the invention (closed), FIG. 3 the locking system according to the invention, the locking rod having broken apart at the predetermined breaking point
  • Fig. 4 shows an arrangement of two locking systems according to the invention, actuated via a base lock (open)
  • Fig. 6 a first conventional locking system (open)
  • Fig. 8 a second conventional locking system (open)
  • a locking rod 4 is mounted in a guide element 6.
  • the guide element 6 is in turn firmly connected to the housing door 1.
  • the locking rod 4 has a locking lug 5.
  • the locking lug 5 of the locking rod 4 engages through an opening in a locking element 12 which is arranged in the housing 13.
  • the closing element 12 is a striking plate which is arranged in a plane perpendicular to the direction of movement of the closing nose 5.
  • the locking lug 5 engages in the guide on the lower edge 11 in the closed state of the guide element 6, which in this embodiment forms the securing element that secures the locking lug 5 against bending.
  • the securing element is accordingly offset relative to the closing element in the direction of the free tip of the closing nose.
  • the locking rod 4 also has a predetermined breaking point 17, which is arranged parallel to the locking lug.
  • the closed position shown in FIG. 2 results from a movement of the closing nose from top to bottom.
  • the movement into the closed position can also take place in the reverse direction, in other words the closed lug is in an open state in its lower position and in a closed state in its upper position.
  • Fig. 3 shows a locking system according to the invention
  • driver 3 is designed to be non-detachable in the preferred embodiment.
  • the driver 3 is first rotatably fitted onto a bolt 8 with a head.
  • the bolt 8 is then tumbled, riveted or welded onto the locking rod 4.
  • the two-part locking system shown here has two locking bars 4 and locking lugs 5, which in are movable in the opposite direction. Both locking lugs can be moved via a base closure 16.
  • the locking rod 24 provided here also has one
  • Locking lug 25 which engages behind a striking plate 27 when the housing door 21 is closed.
  • the locking lug 25 of this conventional locking system is in no way secured against bending.
  • the locking lug 25 will move in a direction opposite to the opening direction of the door 21, i.e. 7, bend to the left, and the door 21 can be opened easily.
  • Locking system in which a locking lug is provided in the locking element 39.
  • a locking element with mushroom head 38 engages in this closing element 39 in order to close the housing door 31.
  • the locking lug of the closing element 39 will bend to the right and thus release the door 31.
  • catch 23/33 and the locking rod 24/34 are detachably connected (e.g. with a screw and a nut 216/316 or with a bolt and a locking ring). Access to the connection, e.g. with a screwdriver is relatively easy.
