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 Ausstellungszwecken dienende Vitrinen weisen minde­stens auf einer Seite eine Öffnung auf, die den Zugang zum Inneren der Vitrine ermöglicht und 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 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.

Die Aufgabe der Erfindung besteht nun darin, eine Vor­richtung zum Verschließen einer derartigen Vitrine anzuge­ben, welche eine einfache Montage erfordert und gegebenen­falls auch eine Montage der vollständigen Vitrine außerhalb der Fertigungsräume durch angelerntes Personal erlaubt.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.

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. Zum Öffnen der Schiebetür wird durch Fließen eines entspre­chenden Gleichstroms durch die Wicklung des oder der Dauer­magnete dessen oder deren magnetisches Feld vorübergehend aufgehoben, so daß dessen oder deren Haltewirkung nicht mehr vorhanden 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. 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.

In diesem Zusammenhang sei noch erwähnt, daß es bereits insbesondere im Möbelsektor Magnetverschlüsse an Türen gibt. Diese stellen jedoch keine Absicherung an sich dar, sondern dienen als Ersatz für die zeitraubendere Betätigung eines Schlüssels. Durch leichten mechanischen Zug sind sie zu öffnen.In this context it should be mentioned that there are already magnetic locks on doors, especially in the furniture sector. However, these are not a safeguard in themselves, but serve as a replacement for the more time-consuming operation of a key. They can be opened by a slight mechanical pull.

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

Vorzugsweise kann das Halterungsteil einen oberen und unteren Träger aufweisen.The holding part can preferably have an upper and lower support.

Eine Weiterbildung der Erfindung besteht darin, daß an der Unterseite oder der Oberseite der Vitrine elektrische Kontakte der Wicklungen der Dauermagnete angebracht sind, an welchen eine äußere oder interne Stromquelle anschließbar ist.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.

Durch die verdeckte Anbringung der Kontakte ist ein ge­wisser Schutz gegen unbefugtes Eindringen in die Vitrine ge­geben. Die externe Stromquelle kann dabei aus einer tragba­ ren Batterie bestehen.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.

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 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.

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 means can be hidden in the showcase, e.g. under the showcase.

Eine vorteilhafte Weiterbildung der Erfindung besteht auch darin, daß der obere und/oder der untere Träger zusätz­lich durch ein Sicherheitsschloß im Schließzustand desselben in der Ruhelage gehalten wird, daß das Sicherheitsschloß mit einem Schaltmittel versehen ist, welches mit der elektri­schen Wicklung eines Dauermagneten verbunden ist, wobei das Schaltmittel durch den Öffnungsvorgang des Sicherheits­schlosses betätigbar ist.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.

Da die Schiebetür durch die Dauermagnete in der Schließstellung gehalten wird, muß die Montage des zusätz­lichen Sicherheitsschlosses nicht so genau erfolgen, wobei das Sicherheitsschloß jedoch zur Sicherheit zum Halten der Glasscheibe in der Ruhelage herangezogen wird, wenn die Glasscheibe mit Gewalt aus der Schließstellung bzw. Ruhelage gebracht werden soll. Über das Sicherheitsschloß kann eine Betätigung der Schaltmittel erfolgen, so daß zumindest die gleiche Sicherheit bei dem Verschluß der Vitrine erreicht wird, als wenn dieser nur mechanisch durch die Sicherheits­ schlösser erfolgt.Since the sliding door is held in the closed position by the permanent magnets, 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.

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. 1 die Ansicht einer Vitrine von vorn und
  • Fig. 2A und 2B eine Ausführungsform der Erfindung bei einer Vitrine.
The invention is explained in more detail with reference to exemplary embodiments which are shown in the drawing. It shows:
  • Fig. 1 is 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 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.

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 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.

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 ange­ brachter 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 brought pole plates 8 in the rest position of the side wall 4. In the case of 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 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.

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.
