Description

Absenk- und Anhebevorrichtung für eine Anzeigeeinrichtung Lowering and lifting device for a display device
Technisches GebietTechnical field
Die Erfindung betrifft eine Absenk- und Anhebevorrichtung für eine Anzeigeeinrichtung.The invention relates to a lowering and lifting device for a display device.
Stand der TechnikState of the art
Für Informationsanzeigen wie sie an Flughäfen oder Bahnhöfen üblicherweise zur Anwendung kommen (z.B. Plasmadisplays, LED-, TFT- oder LCD-Anzeigen) werden bisher starre, rein mechanische Tragkonstruktionen verwendet. Die dazugehörige Informationsanzeige wird dabei in der Regel mittels mehrerer Schrauben fest mit der Tragkonstruktion verbunden.Rigid, purely mechanical support structures have so far been used for information displays such as are usually used at airports or train stations (e.g. plasma displays, LED, TFT or LCD displays). The associated information display is usually firmly connected to the supporting structure by means of several screws.
Unabhängig von der eingesetzten Anzeigentechnik muss an jeder Informationsanzeige in unterschiedlichen Abständen gearbeitet werden; die wöchentliche/monatliche Reinigung, die regelmäßige Inspektion/Wartung, sowie notwendige Reparaturen, Nachjustierungen, oder Austauschaktionen müssen durchgeführt werden.Regardless of the display technology used, each information display must be worked on at different intervals; weekly / monthly cleaning, regular inspection / maintenance, as well as necessary repairs, readjustments, or exchange actions must be carried out.
Bei der herkömmlichen Befestigungsmethode sind hierfür mehr oder weniger umfangreiche Hilfsmittel wie Hubbühnen und/oder Arbeitsplattformen sowie Gerüste erforderlich, um zu der erforderlichen Arbeitshöhe zu gelangen. Zur Einhaltung der Unfallverhütungsvorschriften muss der benötigte Arbeitsbereich zudem abgesichert bzw. abgesperrt werden.With the conventional fastening method, more or less extensive aids such as lifting platforms and / or work platforms and scaffolding are required to achieve the required working height. To comply with the The required work area must also be secured or cordoned off in the event of accident prevention regulations.
Vielfach ist mit der Informationsanzeige eine Ressource wie beispielweise ein Gate- oder Checkln-Counter, ein Ticketschalter oder ein Informations-Counter verbunden. Diese Ressource kann für die Dauer der Arbeiten an der Informationsanzeige nicht genutzt werden, was zu Stress und Verärgerung beim Personal und bei den Passagieren führt.In many cases, the information display is associated with a resource such as a gate or check-in counter, a ticket counter or an information counter. This resource cannot be used for the duration of the work on the information display, which leads to stress and annoyance for the staff and the passengers.
Als Folge der Ressourcensperrung sind teilweise aufwendige Umdisponierungen notwendig, zudem wird das Personal und vor allem aber die Passagiere nicht unerheblich in ihrer Bewegungsfreiheit eingeschränkt.As a result of the blockage of resources, time-consuming rescheduling is sometimes necessary, and the staff and, above all, the passengers are not insignificantly restricted in their freedom of movement.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mittels derer die an Anzeigeeinrichtungen erforderlichen Reinigungs- und Wartungsarbeiten einfacher durchgeführt werden können.The invention has for its object to provide a device by means of which the cleaning and maintenance work required on display devices can be carried out more easily.
Die Lösung dieser Aufgabe erfolgt durch die Absenk- und Anhebevorrichtung nach dem Anspruch 1.This object is achieved by the lowering and lifting device according to claim 1.
Demzufolge weist die Absenk- und Anhebevorrichtung, an der eine Anzeigeeinrichtung abnehmbar anbringbar ist, zwei parallele Teleskopschienen auf, die miteinander verbunden sind und der Führung der Anzeigeeinrichtung beim Absenken und Anheben dienen. Mittels der Teleskopschienen kann die Anzeigeeinrichtung somit von dem im Betrieb erforderlichen Niveau derart abgesenkt werden, dass in einer gewöhnlichen Arbeitshöhe, also ohne die Verwendung von Hubbühnen, Arbeitsplattformen oder dergleichen, die erforderlichen Reinigungs- und Wartungsarbeiten durchgeführt werden können. Nachdem derartige Geräte entfallen, kann auch auf Absperrungen derjenigen Bereiche verzichtet werden, in denen eine Anzeigeeinrichtung zu reinigen oder zu warten ist. Ferner wird der Zeitaufwand für Wartung, Reparatur, Reinigung und gegebenenfalls den Austausch von Anzeigeeinrichtungen erheblich verringert, so dass insgesamt eine höhere Verfügbarkeit der Geräte und Ressourcen erreicht wird, und für den Betreiber deutliche Kostensenkungen möglich sind.Accordingly, the lowering and lifting device, on which a display device can be removably attached, has two parallel telescopic rails which are connected to one another and serve to guide the display device when lowering and lifting. By means of the telescopic rails, the display device can thus be lowered from the level required in operation in such a way that at a normal working height, that is to say without the use of lifting platforms, Work platforms or the like, the necessary cleaning and maintenance work can be carried out. Since such devices are no longer necessary, there is also no need to shut off those areas in which a display device is to be cleaned or serviced. Furthermore, the time required for maintenance, repair, cleaning and, if necessary, the replacement of display devices is considerably reduced, so that overall a higher availability of the devices and resources is achieved and the operator can significantly reduce costs.
Hierbei führt die feste Verbindung zwischen den parallelen Teleskopschienen dazu, dass beim Anheben und Absenken ein zuverlässiger Parallellauf gewährleistet ist, und dass die Konstruktion ferner hinreichend steif ist, so dass die Bedienung äußerst einfach ist. Dies wird dadurch unterstützt, dass die erfindungsgemäße Absenk- und Anhebevorrichtung einen Elektroantrieb aufweist. Ferner ist eine Fernsteuereinheit vorgesehen, so dass die Bedienung erfolgen kann, ohne dass die Betätigung an der nicht ohne weiteres erreichbaren Anzeigeeinrichtung selbst erfolgen muss.The fixed connection between the parallel telescopic rails ensures that a reliable parallel operation is guaranteed when lifting and lowering, and that the construction is also sufficiently rigid so that operation is extremely simple. This is supported by the fact that the lowering and lifting device according to the invention has an electric drive. Furthermore, a remote control unit is provided so that the operation can take place without the actuation itself having to be carried out on the display device which is not easily accessible.
Bevorzugte Weiterbildungen der erfindungsgemäßen Absenk- und Anhebevorrichtung sind in den weiteren Ansprüchen beschrieben.Preferred developments of the lowering and lifting device according to the invention are described in the further claims.
Für die Teleskopschiene hat es sich als vorteilhaft herausgestellt, ein Mehrfach-Teleskopschienen-System zu verwenden, das Ausfahrhübe von 1,00 m bis 3,00 m ermöglicht.For the telescopic rail, it has proven to be advantageous to use a multiple telescopic rail system that enables extension strokes of 1.00 m to 3.00 m.
Ein besonders sicherer Betrieb kann gemäß derjenigen bevorzugten Ausführungsform erreicht werden, bei der eine automatische Endlagensicherung vorgesehen ist. Die erforderliche Steuereinheit kann besonders einfach gehalten werden, wenn die Fernsteuereinheit, wie bevorzugt vorgesehen, für die Bedienung mehrerer Absenk- und Anhebevorrichtungen kodierbar ist.Particularly safe operation can be achieved according to the preferred embodiment in which an automatic end position safeguard is provided. The required control unit can be kept particularly simple if the remote control unit, as is preferably provided, can be coded for the operation of a plurality of lowering and lifting devices.
