Definitions

  • the invention relates to a device for locking at least one floppy disk drive of a floppy disk drive station of a computer, the floppy disk drive station being provided with a housing front having the insertion slot or slots of the diskette drive (s) and two station side walls, each with a vertical slot or a corresponding recess in the Distance from the front of the housing.
  • Computers in particular so-called personal computers, are equipped with a floppy disk drive station with at least one, but preferably several, for example two or three, floppy disk drives.
  • Such computers have to be used, for example, by insurance companies, banks and similar service providers, but also in the industry for many people be accessible. However, it sometimes happens that the computer or at least one of the floppy disk drives is not to be released for all users, but only for a limited number of users in order to prevent misuse in this regard.
  • the object of the invention is to provide a device of the type mentioned, with the help of which one or all of the floppy disk drives of a floppy disk drive station or at least one of the floppy disk drives of the floppy disk drive station can be locked for a specific group of people and released to other users if necessary.
  • This device is placed over the operating side of the diskette drive station like a hood.
  • the locking members are in their ineffective position. Because the device housing matches the housing of the
  • Floppy disk drive station is precisely adapted, it takes up just about the correct position in relation to the floppy disk drive (s) just by completely sliding it open, so that the or all floppy disk drives, or in several, the desired or the desired floppy disk drives are automatically covered and thus in or the covered ones Diskette drives no diskette can be inserted.
  • the locking members When the device is fully pushed open, the locking members are actuated, whereby their free ends enter the existing vertical slots or troughs of the station side walls.
  • the ends of the locking members are dimensioned such that on the one hand they can be easily inserted into the longitudinal slots or troughs of the station housing, but on the other hand the device is held to the disk drive station to some extent in a vibration-proof manner.
  • the device is securely held on the disk drive unit and can then fulfill the intended purpose. Only authorized persons can unlock the locking members and remove the device so that they can then access all or also the disk drive (s) intended only for them. If you do not lock all floppy drives, you can have a non-preferred employee, for example a bank, use this floppy drive station, but prevent him from using the sensitive floppy drive (s) that are only intended for a few.
  • Part of the curved or angled locking lug extends, namely the one that immediately adjoins the base body, to a certain extent outside the side wall of the device housing. This leads on the one hand to a narrow construction of the device housing, and on the other hand one can easily recognize the position of the locking members in this way.
  • This training also has advantages in terms of activity. If you prefer to produce the housing from sheet metal, you can easily punch out the necessary slots for the locking members.
  • a further embodiment of the invention results from claim 4. It is assumed here that the station housing is in the usual way an upright cuboid, and in this respect the "transverse direction" corresponds to the horizontal direction. It contributes to the simpler construction and assembly method if the pins are attached to the front wall of the device. This is therefore not perforated at the point in question and the slots are then protected behind the front wall of the device.
  • the device can be significantly simplified if it is developed in a very advantageous manner according to claim 5.
  • a particularly preferred embodiment of the invention is described in claim 6.
  • the locking member mentioned there can be moved up and down transversely to the sliding direction of the locking members and thus in the vertical direction. If its raised position is the ineffective position, the locking member must be lifted before the device housing is plugged onto the station housing and, if necessary, held in place during this, unless no other possibility is provided. After taking the correct position of the device housing relative to the station housing, the locking members are brought into their locked position. It is particularly advantageous if the locking lugs, as described above, are guided outwards because you can then easily move them into the locked position by hand by pressing directly on the locking tabs. If you now release the locking member, it will fall - if its unlocked position is the raised position - at least due to its own weight. You can use a spring to support it. The locking member must now be secured against unauthorized unlocking in a suitable manner.
  • the or each locking bolt of the locking member engages in two locking receptacles congruent in the locking position of the locking members, this leads to a further simplification in the manufacture of the individual parts.
  • the locking bolt can only enter these locking receptacles if they are in immediate succession and are in its range of motion. You can now form the locking members so that the locking bolt in the release position of the locking member is supported on top of them, so that it automatically enters the locking receptacles downwards as soon as the locking members have reached their locking position.
  • the locking bolt engages in the lowered position in the locking receptacles and these are formed by upwardly open slots in the locking members.
  • the free upper mouths of the locking receptacles are in the release position of the locking member and locking member on the left and right of the associated locking member.
  • one of the locking receptacles gets under the raised supporting element.
  • the locking member can still not lower. Only when the second locking member has also taken its locking position is its locking receptacle in the range of motion of the support member, so that the locking member now moves automatically or downwards can move.
  • At least one pin is used in three ways, or in other words, for all displaceable parts of the device, which of course means a simplification of the entire device. As a result, it is not only cheaper to manufacture, but also less prone to failure.
  • the raised position of the locking member is its release position.
  • the locking member which is inherently displaceable from the outside, cannot be raised and brought into the ineffective position.
  • Claim 12 contains a further development of the invention. It concerns the main field of application for this device, i.e. , it should be used above all where a floppy disk drive station has at least two drives arranged one above the other, one or at least one of which is to be locked. This is preferably the top one.
  • the locking elements are located in the area of the drive or a drive underneath, which in many cases takes up more space than the one or the two above.
  • the arrangement of the locking links can be based on the longitudinal slots or troughs in the station housing.
  • a further embodiment of the invention provides that a side wall of the device housing carries an extension tab which covers at least one mounting screw of the station housing.
  • an extension tab which covers at least one mounting screw of the station housing.
