Ein wesentlicher Punkt der Erfindung liegt darin, dass eine FĆ¼hrungsplatte vorgesehen ist, die mit Ausnehmungen ausgestattet ist. Dadurch mĆ¼ssen keine zusƤtzlichen Schienen hergestellt und angeschweiĆt werden, was den Material-, Arbeits- und Kostenaufwand erheblich reduziert. AuĆerdem kƶnnen die entsprechenden Ausnehmungen ƤuĆerst prƤzise und reproduzierbar hergestellt werden. Auch kann keine ungewollte relative Verschiebung zwischen Seitenplatten und FĆ¼hrungsschienen - wie beispielsweise im Stand der Technik gemĆ¤Ć der

In this area a particularly simple and precise guidance of the sliding elements is made possible.
In einer bevorzugten AusfĆ¼hrungsform sind die spiralfƶrmig verlaufenden Ausnehmungen in den FĆ¼hrungsplatten durch Laserschnitt erhalten. Dadurch lassen sich die Ausnehmungen ƤuĆerst prƤzise anfertigen. Insbesondere entstehen keine SchweiĆraupen od. dgl. Alternativ kƶnnen die Ausnehmungen bzw. die FĆ¼hrungsplatte auch mittels Metalldruckguss hergestellt werden.In a preferred embodiment, the spirally extending recesses in the guide plates are obtained by laser cutting.

Vorzugsweise sind die etwa spiralfƶrmigen Ausnehmungen innerhalb der FĆ¼hrungsplatte durchgehend ausgebildet, so dass mƶgliche Variationen bezĆ¼glich der Position der FĆ¼hrungsplatte in Bezug auf die seitliche Grubenwand keine ungewollte Reibung zur Folge haben.Preferably, the approximately spiral-shaped recesses are formed continuously within the guide plate so that possible variations in the position of the guide plate with respect to the lateral pit wall do not result in unwanted friction.
Alternativ kƶnnen die etwa spiralfƶrmig verlaufenden Ausnehmungen auch nicht-durchgehend bzw. U-fƶrmig ausgebildet sein.Alternatively, the approximately spiral-shaped recesses may also be non-continuous or U-shaped.
Vorzugsweise ist die Speichereinheit als eine Baueinheit ausgebildet.

As a result, the storage unit can be made very compact and the assembly effort in the construction of the mounting pit is reduced.
In einer bevorzugten AusfĆ¼hrungsform erstreckt sich die Speichereinheit Ć¼berwiegend in Vertikalrichtung, wobei das VerhƤltnis zwischen Vertikalerstreckung und Horizontalerstreckung vorzugsweise in einem Bereich von 1,3 bis 3,0 insbesondere von 1,7 bis 2,5, beispielsweise etwa 1,9 liegt. Dadurch wird der durch die Speichereinheit beanspruchte Platz in horizontaler Richtung reduziert.In a preferred embodiment, the memory unit extends predominantly in the vertical direction, wherein the ratio between vertical extent and horizontal extent is preferably in a range from 1.3 to 3.0, in particular from 1.7 to 2.5, for example approximately 1.9. This reduces the space occupied by the memory unit in the horizontal direction.
Vorzugsweise befindet sich eine Antriebsachse mit zumindest einem zugehƶrigen Antriebsrad in einem Ein- und Austrittsbereich des Tragbalkenbandes oberhalb der etwa spiralfƶrmig verlaufenden FĆ¼hrungen. Eine solche MaĆnahme trƤgt ebenfalls zu einer geringen Horizontalerstreckung und einer kompakten AusfĆ¼hrung der Speichereinheit bei.Preferably, there is a drive axle with at least one associated drive wheel in an entry and exit region of the support beam above the approximately spirally extending guides. Such a measure also contributes to a small horizontal extent and a compact design of the storage unit.
Vorzugsweise kann die Speichereinheit fĆ¼r eine rolladenartige Abdeckung verwendet werden, wobei die rolladenartige Abdeckung aus mehreren Tragbalken besteht, die eine mit zumindest einem Verbindungsmittel, insbesondere einer Fƶrderkette, zu einem Tragbalkenband zusammengesetzte Abdeckung bilden, welche mittels den Tragbalken zugeordneter FĆ¼hrungsrollen verschiebbar in FĆ¼hrungen gelagert ist, wobei die FĆ¼hrungsrollen und/oder das Verbindungsmittel zumindest teilweise in Ausnehmungen der zugehƶrigen Tragbalken oder deren stirnseitigen Bereichen aufgenommen sind, wodurch die aus den jeweiligen Tragbalken und zugehƶrigen FĆ¼hrungsrollen sowie Verbindungsmitteln resultierende Gesamtbauhƶhe gering gehalten ist, wobei an beiden Stirnseiten der Tragbalken jeweils TragbalkenverlƤngerungen angeordnet sind, die durch Winkelprofile gebildet und in denen die Ausnehmungen ausgebildet sind, wobei ein Schenkel der Winkelprofile eine bĆ¼ndige VerlƤngerung der TragbalkenoberflƤche darstellt und ein anderer Schenkel der Winkelprofile mit dem Tragbalken verbunden, insbesondere verschweiĆt ist.Preferably, the storage unit can be used for a roller shutter-like cover, wherein the roller shutter-like cover consists of a plurality of support beams, which form a composite with at least one connecting means, in particular a conveyor chain, to a support band cover, which is mounted by means of the support bar associated guide rollers slidably in guides, wherein the guide rollers and / or the connecting means are at least partially accommodated in recesses of the associated support beams or their frontal areas, whereby the overall height resulting from the respective support beams and associated guide rollers and connecting means is kept small, wherein support beams extensions are arranged on both end faces of the support beams, formed by angle profiles and in which the recesses are formed, wherein a leg of the angle profiles represents a flush extension of the supporting beam surface u nd another leg of the angle profiles connected to the support beam, in particular welded.
Vorzugsweise sind die Tragbalken durch zwei, parallel zu den FĆ¼hrungen verlaufenden Buchsenfƶrderketten miteinander verbunden, wobei jeder Tragbalken ein Glied der Buchsenfƶrderkette bildet, deren Gelenke jeweils den Spalten zwischen den Tragbalken zugeordnet sind und wobei die einzelnen Glieder einer Gelenkkette in den Ausnehmungen der Tragbalken, insbesondere an deren Unterseite, angeordnet sind.Preferably, the support beams are interconnected by two, parallel to the guides running bushing conveyor chains, each support beam forms a member of the Buchsenfƶrderkette, the joints of each of the Columns are assigned between the support beams and wherein the individual members of a link chain in the recesses of the support beams, in particular on the underside, are arranged.
Weiterhin kƶnnen die FĆ¼hrungsrollen auf Bolzen, welche die einzelnen Glieder der Buchsenfƶrderkette miteinander verbinden und die Gelenkachsen definieren, axial auĆerhalb der einzelnen Gelenke gelagert sein.Furthermore, the guide rollers may be mounted on bolts, which connect the individual members of the bushing conveyor chain together and define the hinge axes, axially outside of the individual joints.
Da Ausnehmungen im Tragbalken denselben signifikant schwƤchen, sind TragbalkenverlƤngerungen von Vorteil, da dann an den Stellen, an denen die Ausnehmungen vorgesehen sind, ein besonders belastbares Material eingesetzt werden kann. Dadurch wird eine SchwƤchung des Tragbalkens an dieser Stelle wirkungsvoll verhindert. Eine ausreichende StabilitƤt der gesamten Abdeckung ist somit sichergestellt. Winkelprofile haben sich als vorteilhafte TragbalkenverlƤngerung erwiesen, wobei ein Schenkel als bĆ¼ndige VerlƤngerung der jeweils zugeordneten TragbalkenoberflƤche vorgesehen ist und der andere Schenkel mit jeweils einer zugeordneten Stirnseite eines zugehƶrigen Tragbalkens verbunden ist. Als Verbindung eignet sich insbesondere eine VerschweiĆung. Alternativ sind auch andere Verbindungen mƶglich.Since recesses in the support beam significantly weaken the same, support beam extensions are advantageous since then a particularly resilient material can be used at the locations where the recesses are provided. As a result, a weakening of the supporting beam is effectively prevented at this point. Sufficient stability of the entire cover is thus ensured. Angle profiles have proven to be advantageous TragbalkenverlƤngerung, with one leg is provided as a flush extension of the respectively associated support beam surface and the other leg is connected to an associated end face of an associated support beam. As a compound is in particular a weld. Alternatively, other connections are possible.
An der Unterseite der horizontalen Schenkel der Winkelprofile kƶnnen die FĆ¼hrungsrollen und/oder Verbindungsmittel befestigt sein. Die Befestigung kann mittels Verschraubung, VerschweiĆung oder anderweitig erfolgen.At the bottom of the horizontal legs of the angle profiles, the guide rollers and / or connecting means may be attached. The attachment can be done by screwing, welding or otherwise.
