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 for exhibition purposes have an opening on at least one side that allows access to the inside of the showcase, often through a sliding door.
  • Security locks are used to secure the sliding door in the closed or rest position, in order to protect the often valuable content 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.
  • a device which has pivotable doors with magnetic lock, in which a component is also provided, which consists of magnetic flux-conducting material and is held in the closed position by at least one permanent magnet.
  • a component which consists of magnetic flux-conducting material and is held in the closed position by at least one permanent magnet.
  • the invention is based on the object of specifying a device for closing a showcase of the type mentioned at the outset, which requires simple assembly and, if appropriate, also allows assembly of the complete showcase 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.
  • the security lock is provided with a switching means which is connected to the winding of the permanent magnet or magnets, wherein the switching means can be actuated by the opening process of the security lock.
  • 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 external power source can consist of a portable battery.
  • a further development of the invention also consists in the fact that a power supply device is provided in the showcase, which is fed from the general power network and can be connected to the electrical windings of the permanent magnets via switching means.
  • the switching device can be installed in a hidden place in the showcase, for example under the showcase.
  • the showcase 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 support 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 showcase, so that the displaceable side wall 4 can be pushed sideways, so as to open up access to the inside of the showcase.
  • 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 Hold the 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 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.
