Definitions

  • the invention relates to a device for closing a sliding door of a display case having a frame construction according to the preamble of claim 1.
  • Showcases used for exhibition purposes have an opening on at least one side that allows access to the inside of the showcase and often through a sliding door.
  • Security locks are used to secure the sliding door in the closed position or in the rest position, in order to protect the often valuable contents from unauthorized access.
  • These security locks must be installed very precisely so that the sliding door has no play in the closed position. The assembly is therefore very time-consuming and makes the manufacture of such a display case more expensive. The locks are often difficult to reach.
  • the object of the invention is to provide a device for closing such a display case, which requires simple assembly and, if appropriate, also allows assembly of the complete display case outside the production rooms by trained personnel.
  • the permanent magnets attached to the showcase body hold the holding part or the pole plate on the sliding door, so that the permanent magnets do not have to be assembled exactly or the permanent magnets are easily adjustable.
  • To open the sliding door its magnetic field is temporarily canceled by flowing a corresponding direct current through the winding of the permanent magnet or magnets, so that its or its holding effect is no longer present.
  • the device according to the invention enables the secure closure of sliding doors even in places where conventional locking devices are difficult to reach.
  • the holding part can preferably have an upper and lower support.
  • a further development of the invention is that electrical contacts of the windings of the permanent magnets are attached to the underside or the top of the display case, to which an external or internal current source can be connected.
  • the hidden attachment of the contacts provides a certain level of protection against unauthorized entry into the showcase.
  • the external power source can be from a portable battery.
  • a further development of the invention is that a power supply device is provided in the showcase, which is fed from the general power supply and can be connected to the electrical windings of the permanent magnets via switching means.
  • An advantageous development of the invention also consists in the fact that the upper and / or the lower carrier is additionally held in the rest position by a safety lock in the closed state thereof, that the safety lock is provided with a switching means which is connected to the electrical winding of a permanent magnet, wherein the switching means can be actuated by the opening process of the security lock.
  • the installation of the additional security lock does not have to be carried out as precisely, although the security lock is used for safety to hold the glass pane in the rest position when the glass pane is forced out of the closed position or rest position to be brought.
  • the switching means can be actuated via the security lock, so that at least the same security is achieved when the display case is closed as if it were only mechanically by the security locks.
  • the display case has an upper part 1 and a lower part 2. In between is the exhibition space, which is formed by side walls 3 and can be closed by a sliding door 4.
  • the side walls 3 and 4 can be made of glass.
  • the displaceable side wall is held by an upper and a lower support 6 and 13, respectively.
  • an upper and a lower bracket 6 and 13 are held by a parallel guide 14 attached to the inner frame 12 of the display case. This enables the horizontal movement of the carriers 6 and 13 out of the display case, so that the displaceable side wall 4 can be pushed sideways, so as to give access to the interior of the display case.
  • one or more permanent magnets 7 are attached in such a way that the upper support 6 or the lower support 13 is attached to them brought pole plates 8 in the rest position of the side wall 4.
  • several permanent magnets 7 can act on one carrier.
  • the permanent magnets 7 each have an electrical winding, not shown, which serves to cancel the magnetic field of the permanent magnet 7. This is done by flowing an electrical direct current of the appropriate size and polarity.
  • a battery can be used as the power source, which is connected via contacts concealed on the outside, e.g. under the showcase body, with the winding of the permanent magnets 7 can be connected.
  • security locks 9 can be attached in the upper part 1 and / or in the lower part 2 of the display case, which hold the carriers 6 and 13 in addition to the permanent magnets in the closed position.
  • the security locks 9 can have switching means, not shown, which are actuated during the opening process and cause a brief current flow in the windings of the permanent magnets during the rotation of the key, which results in the release of the carriers 6 and 13, respectively.
  • a current supply device is provided as the current source, which is fed from the light network and connected to the windings of the permanent magnets 7 via the switching means or the switching means.
