Definitions

  • the present invention relates to a device for securing housing openings and / or operating elements of electronic devices against unauthorized access.
  • Computers, devices for communications and communication technology and multimedia devices have devices for data carriers or control elements, the use of which must be restricted or regulated.
  • drives for data backup (streamer) or CD-ROM drives usually contain sensitive data or data carriers of high material value, the protection of which from theft or manipulation is required.
  • a device for securing housing openings and / or operating elements of electronic devices against unauthorized access is therefore provided, with a cover housing which has a lock with a locking mechanism and an engagement element and on the opening to be secured or via the

  • the locking mechanism of the lock and the engagement element of the cover housing can be brought into engagement with these recesses on the device side, as a result of which an unauthorized removal of an attached and closed cover housing is impossible and thus access to the housing opening to be secured or the control element for unauthorized persons becomes impossible.
  • the engaging element can be a strip which can be inserted into a recess designed as a groove.

  • These two depressions can be aligned parallel to one another and further such that the first groove and the latter groove are oriented identically with respect to the housing.
  • the cover housing can enclose at least one of the device-side recesses (grooves) so that displacement of the cover housing along the at least one recess is prevented and thus removal of a closed cover housing by lateral displacement along the recesses is impossible.
  • a profile rail can be attached to the housing of the electronic device to form a groove.
  • the cover housing is composed of a first part having the lock and a second part having the engagement element, which are firmly connected to one another.
  • Different width dimensions of the housing opening to be secured and / or of the operating element can thus be compensated for by appropriately selecting the width of the second part having the engagement element.
  • the dimension of the locking mechanism for example a bolt, can thus remain constant since the distance between the bolt and the closing groove remains unchanged.
  • the second part can engage with pegs in depressions in the first part.
  • the second part can be connected to the first part in the manner of a tongue and groove.
  • the firm connection can be made, for example, by gluing.
  • recesses can be provided in the cover housing to enable actuation of this selected control element. These recesses are chosen so that the actuation of the controls, which are not to be accessed, is still reliably prevented.

  • the bolt 3 is then brought from the unlocked position A shown in broken lines to the locking position B shown with solid lines, in which it comes into engagement with the groove 6 of the profile rail 9. Since the cover housing 1 is flush with the outer edges of the rails 8, 9, thus in the locked position, a removal of the cover housing 1 is neither upwards nor by lateral displacement along the

  • a particular advantage of a device according to the invention is that the recesses 5, 6 of the profile rails 8, 9, which, for example when retrofitting, possibly form the weakest point of the securing device, are not accessible from the outside in the mounted, locked state of the cover housing 1 and from therefore cannot be subjected to violence.
  • the function of the housing opening or the control element remains fully maintained even when the cover housing 1 is in place, and the installation of the cover housing 1 requires so little effort and time that it can be accomplished even when the workplace is briefly left.
  • a data carrier inserted in a drive is secured against unauthorized removal. In the event that an unauthorized person succeeds in forcibly removing the cover housing and thus destroying it, this does not go unnoticed by the authorized person and gives him the opportunity to check his data stock with regard to data that has been introduced or removed.
