Abstract

The sliding door of showcases is normally closed by means of safety locks, but these have to be installed with a high degree of accuracy if the side wall is to have no play in the position of rest. The new device will likewise make it possible to close a showcase securely, but without having to ensure particular accuracy during installation. The sliding door 4 is held in the closing position or position of rest by permanent magnets 7 which are attached to the showcase and the magnetic field of which can be cancelled via an electrical winding by the flow of an appropriate direct current. Since the permanent magnets do not have to be installed with such accuracy, the assembly of a showcase of this type can also be carried out outside a workshop, for example a building site. Furthermore, the secure closing of sliding doors can thus be brought about, even in places where conventional closing devices would be accessible only with difficulty. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Verschließen einer Schiebetür einer eine Rahmenkonstruktion aufweisenden Vitrine gemäß dem Oberbegriff des Anspruchs 1.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.

Zu Austellungszwecken dienende Vitrinen weisen mindestens auf einer Seite eine Öffnung auf, die den Zugang zum Inneren der Vitrine ermöglicht und zwar vielfach durch eine Schiebetür. Zur Sicherung der Schiebetür in der Schließstellung oder Ruhelage dienen Sicherheitsschlösser, um den oft wertvollen Inhalt vor unbefugtem Zugriff zu schützen. Die Montage dieser Sicherheitsschlösser muß sehr exakt erfolgen, damit die Schiebetür in der Schließstellung kein Spiel hat. Die Montage ist deshalb sehr zeitraubend und verteuert die Herstellung einer solchen Vitrine. Die Schlösser sind oft nur schwer erreichbar.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.

Es ist bereits eine Vorrichtung zum Verschließen einer Schiebetür einer eine Rahmenkonstruktion aufweisenden Vitrine der eingangserwähnten Art bekannt (DE-A 2 237 395), bei der die angegebene Konstruktion mit horizontaler und seitlicher Verschiebung der Schiebetür dazu dient, einen möglichst staubfreien Verschluß der Vitrine mit Hilfe der Schiebetür zu erreichen. Es ist eine Schließvorrichtung vorgesehen, durch die die Schiebetür verschlossen werden kann. Die Montage der Schließvorrichtung ist bei einer möglichst staubfreien Abdichtung jedoch schwierig und die Schließvorrichtung kann zur exakten Einpassung vorzugsweise nur in besonderen Fertigungsräumen von besonders geschultem Personal montiert werden. Selbst bei einer exakten Einpassung läßt sich bei großen Schiebetüren jedoch ein staubfreier Verschluß kaum erreichen.There is already known a device for closing a sliding door of a display case having a frame construction of the type mentioned (DE-A 2 237 395), in which the specified construction with horizontal and lateral displacement of the sliding door serves to close the display case as dust-free as possible with the help to reach the sliding door. A locking device is provided through which the sliding door can be locked. The assembly of the locking device is difficult with a dust-free seal, however, and the locking device can only be fitted by specially trained personnel, preferably in special production rooms, for exact fitting. Even with an exact fit, however, a dust-free lock can hardly be achieved with large sliding doors.

Es ist andererseits eine Vorrichtung bekannt (US-A-2 888 290), die schwenkbare Türen mit Magnetverschluß aufweist, bei denen ebenfalls ein Bauteil vorgesehen ist, das aus magnetflußleitendem Material besteht und durch mindestens einen Dauermagneten in der Schließstellung gehalten wird. Es ist ebenfalls bei dieser Anordnung eine Spule zur Aufhebung der Magnetkraft des Dauermagneten vorgesehen, jedoch befindet sich diese in der Tür. Zweck der Anordnung ist es, die Haltekraft des Magneten elektrisch zu beeinflussen und um die Tür leichter öffnen zu können.On the other hand, a device is known (US-A-2 888 290) 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. In this arrangement there is also a coil for canceling the magnetic force of the permanent magnet, but this is located in the door. The purpose of the arrangement is to influence the holding force of the magnet electrically and to be able to open the door more easily.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Verschließen einer Vitrine der eingangs erwähnten Art anzugeben, welche eine einfache Montage erfordert und gegebenenfalls auch eine Montage der vollständigen Vitrine außerhalb der Fertigungsräume durch angelerntes Personal erlaubt.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.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Die am Vitrinenkörper angebrachten Dauermagnete halten das Halterungsteil bzw. die Polplatte an der Schiebetür fest, so daß die Montage der Dauermagnete nicht genau erfolgen muß bzw. die Dauermagnete leicht justierbar sind. Ferner ist das Sicherheitsschloß mit einem Schaltmittel versehen, welches mit der Wicklung des oder der Dauermagnete verbunden ist, wobei das Schaltmittel durch den Öffnungsvorgang des Sicherheitsschlosses betätigbar ist.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. Furthermore, 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.

Zum Öffnen der Schiebetür wird bei Betätigung des Sicherheitsschlosses durch Fließen eines entsprechenden Gleichstroms durch die Wicklung des oder der Dauermagneten dessen oder deren magnetisches Feld vorübergehend aufgehoben, so daß dessen oder deren Haltewirkung nicht mehr vorhanden ist. Entsprechend wird das Sicherheitsschloß gelöst und die Schiebetür kann verfahren und verschoben werden.To open the sliding door, when the safety lock is actuated, a corresponding direct current flows through the winding of the permanent magnet (s) to temporarily suspend its magnetic field, so that its holding effect is no longer present. The safety lock is released accordingly and the sliding door can be moved and moved.

Durch die erfindungsgemäße Vorrichtung läßt sich wie schon weiter oben ausgeführt, der sichere Verschluß von Schiebetüren selbst an Stellen, an denen herkömmliche Schließvorrichtungen nur schwer erreichbar sind, ermöglichen.As already explained above, the device according to the invention enables the secure closure of sliding doors even in places where conventional locking devices are difficult to reach.

Durch verdeckte Anbringung der Kontakte ist ein gewisser Schutz gegen unbefugtes Eindringen in die Vitrine gegeben. Die externe Stromquelle kann dabei aus einer tragbaren Batterie bestehen.A hidden protection against unauthorized entry into the showcase is provided by the hidden attachment of the contacts. The external power source can consist of a portable battery.

Eine Weiterbildung der Erfindung besteht auch darin, daß in der Vitrine eine Stromversorgungseinrichtung vorgesehen ist, welche aus dem allgemeinen Stromnetz gespeist wird und über Schaltmittel mit den elektrischen Wicklungen der Dauermagnete verbindbar ist.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.

Da Vitrinen oftmals in ihrem Oberteil eine Beleuchtungseinrichtung aufweisen, ist ohnehin ein Anschluß an das allgemeine Stromnetz vorhanden, welcher auch für die Stromversorgungseinrichtung benutzt werden kann. Das Schaltmittel kann aus Sicherheitsgründen an einer verdeckten Stelle in die Vitrine, z.B. unter der Vitrine, eingebaut werden.Since showcases often have a lighting device in their upper part, there is a connection to the general power supply anyway, which can also be used for the power supply device. For safety reasons, the switching device can be installed in a hidden place in the showcase, for example under the showcase.

Weitere Vorteile ergeben sich aus den weiteren Unteransprüchen.Further advantages result from the further subclaims.

Die Erfindung wird anhand von Ausführungsbeispielen näher erläutert, welche in der Zeichnung dargestellt sind. Es zeigt:

Fig. 2A und 2B
eine Ausführungsform der Erfindung bei einer Vitrine.
The invention is explained in more detail by means of exemplary embodiments which are shown in the drawing. It shows:
Fig. 1
the view of a showcase from the front and
2A and 2B
an embodiment of the invention in a showcase.

Die Vitrine weist ein Oberteil 1 und ein Unterteil 2 auf. Dazwischen liegt der Ausstellungsraum, welcher durch Seitenwände 3 gebildet und durch eine Schiebetür 4 verschließbar ist. Die Seitenwände 3 und 4 können aus Glas bestehen. Die verschiebbare Seitenwand wird von einem oberen und einem unteren Träger 6 bzw. 13 gehalten.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.

Bei der verschiebbaren Seitenwand 4 werden ein oberer und ein unterer Träger 6 bzw. 13 durch eine am Innenrahmen 12 der Vitrine angebrachte Parallelführung 14 gehalten. Diese ermöglicht die horizontale Bewegung der Träger 6 bzw. 13 aus der Vitrine heraus, so daß die verschiebbare Seitenwand 4 seitlich weggeschoben werden kann, um so den Zugang zum Inneren der Vitrine freizugeben.In the sliding side wall 4, 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.

Am Innenrahmen 12 der Vitrine sind ein oder mehrere Dauermagnete 7 derart angebracht, daß diese den oberen Träger 6 bzw. den unteren Träger 13 mittels an diesen angebrachter Polplatten 8 in der Ruhelage der Seitenwand 4 halten. Bei der verschiebbaren Seitenwand 4 wird es zweckmäßig sein, mindestens je einen Dauermagneten so anzubringen, daß dieser auf die Mitte des jeweiligen Trägers 6 bzw. 13 wirkt. Ebenso können auch mehrere Dauermagnete 7 auf einen Träger wirken.On the inner frame 12 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. With the displaceable side wall 4, it will be expedient to attach at least one permanent magnet each so that it acts on the center of the respective carrier 6 or 13. Likewise, several permanent magnets 7 can act on one carrier.

Die Dauermagnete 7 weisen jeweils eine nicht gezeigte elektrische Wicklung auf, die dazu dient, das Magnetfeld des Dauermagneten 7 aufzuheben. Dies geschieht durch Fließen eines elektrischen Gleichstroms entsprechender Größe und Polarität. Als Stromquelle kann eine Batterie dienen, die über an der Außenseite verdeckt angebrachte Kontakte, z.B. unter dem Vitrinenkörper, mit der Wicklung der Dauermagnete 7 verbindbar ist.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.

Weiterhin können Sicherheitsschlösser 9 im Oberteil 1 und/oder im Unterteil 2 der Vitrine angebracht sein, welche in der Schließstellung zusätzlich zu den Dauermagneten die Träger 6 bzw. 13 halten. Die Sicherheitsschlösser 9 können nicht gezeigte Schaltmittel aufweisen, welche beim Öffnungsvorgang betätigt werden und während der Drehbewegung des Schlüssels einen kurzzeitigen Stromfluß in den Wicklungen der Dauermagnete bewirken, der eine Freigabe der Träger 6 bzw. 13 zur Folge hat. Als Stromquelle ist eine Stromversorgungseinrichtung vorhanden, die aus dem Lichtnetz gespeist über das bzw. die Schaltmittel mit den Wicklungen der Dauermagnete 7 verbunden ist.Furthermore, 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.
