Description

Die Erfindung betrifft eine Auszugssicherung gemäß dem Oberbegriff des Hauptanspruches.The invention relates to an extract safety according to the preamble of the main claim.

Aus Gehäusen ausziehbare Rollfedern sind in vielerlei Ausführungsformen bekannt, etwa für Maßbänder oder etwa die Warenvorschübe von Warenpräsentationssystemen, wobei Ausführungsformen bekannt sind, bei denen bei Vollauszug einer Feder diese aus dem Gehäuse springt, mit dem Nachteil einer erheblichen Verletzungsgefahr und der anschließende Funktionsuntüchtigkeit des gesamten Bauteils. Andere Auszüge sind beispielsweise schienengeführt und der Federauszug über die vorgegebene Schienenlänge begrenzt, wobei eine solche Schiene verhältnismäßig kostenaufwendig ist und die gesamte Einrichtung verunziert. Auch hier kann die Feder bei unsachgemäßem Umgang angehoben und aus dem Gehäuse herausgezogen werden.Extending from housings roller springs are known in many embodiments, such as tape measures or about the product feeds of goods presentation systems, embodiments are known in which full extension of a spring this jumps out of the housing, with the disadvantage of a considerable risk of injury and the subsequent inoperability of the entire component , Other extracts are, for example, rail-guided and limited the spring extension over the predetermined rail length, such a rail is relatively expensive and denounced the entire device. Again, the spring can be raised when improper handling and pulled out of the housing.

Bei einer bekannten Ausführungsform eines Warenpräsentationssystems gemäß der DE 29910016 U1 ist das Federende zu einem geschlossenen Auge verschweißt, in dem das Ende der Rollfeder mit der ersten Lage einer Wicklung zu einem geschlossenen Ring verbunden ist, bzw. ist das Federende zu einem Haken umgebogen, welcher in einem Schlitz einer tonnenförmigen Welle eingeführt und festgelegt ist. Nachteilig ist bei der verschweißten Ausführungsform insbesondere der dadurch entstehende Kostenaufwand, ebenso wie eine Variante mit hakenförmigem Federende die Verwendung einer festen Achse verbietet und der Rücklauf der Feder nach einem Vollauszug entweder unmöglich oder sehr hakelig ist.In a known embodiment of a goods presentation system according to the DE 29910016 U1 the spring end is welded to a closed eye, in which the end of the scroll spring is connected to the first layer of a winding to a closed ring, or the spring end is bent into a hook, which is inserted and fixed in a slot of a barrel-shaped shaft. A disadvantage of the welded embodiment, in particular the resulting cost, just as a variant with hook-shaped spring end prohibits the use of a fixed axis and the return of the spring after a full extension is either impossible or very hakelig.

Bei einer anderen bekannten Ausführung einer Auszugssicherung ist das Federende gelocht und wird vor Verlassen des Gehäuses durch einen Sicherungsstift aufgefangen. Auch hier ist der Rücklauf nicht gewährleistet und das Produkt anschließend funktionsuntüchtig.In another known embodiment of a pull-out protection, the spring end is perforated and is collected before leaving the housing by a locking pin. Again, the return is not guaranteed and the product then dysfunctional.

Aufgabe der Erfindung ist es, eine Auszugssicherung einer Rollfeder aus einem Gehäuse zur Verfügung zu stellen, welche einfach und kostengünstig herzustellen ist und die die anschließende Funktionstüchtigkeit nach einem Vollauszug gewährleistet.The object of the invention is to provide a pull-out protection of a scroll spring from a housing available, which is simple and inexpensive to manufacture and ensures the subsequent functionality after a full extension.

Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Oberbegriffsmerkmalen erfindungsgemäß mittels der Merkmale des kennzeichnenden Teils des Hauptanspruches. Dadurch, dass die Rollfeder im Bereich ihres Endes mindestens eine Ausnehmung aufweist und im Gehäuse eine korrespondierende Rastnocke angeordnet ist, die Rollfeder über ihre Funktionslänge über eine Gleitfläche dieser Rastnocke gleitet, die erst im Bereich des Endes der Rollfeder in deren Ausnehmung eingreift und so die Rollfeder gegen einen vollständigen Auszug aus dem Gehäuse sichert, wird zum einen eine sehr wirtschaftliche Lösung erzielt, da bei der Herstellung der von einem Federband abzulängenden Rollfeder gleichzeitig das Ende der Rollfeder und der Anfang der nächsten Rollfeder mittels eines gemeinsamen Werkzeuges bearbeitet wird, so dass zur Herstellung der Ausnehmungen kein zusätzlicher Arbeitsschritt erforderlich ist und auch kein weiteres Bauteil hinzugefügt werden muss. Zum anderen ist von besonderem Vorteil, dass sich die Feder nach Lösen einer Zugbelastung Feder wieder zusammenrollen kann, so dass diese beliebig häufig unter vollständiger Aufrechterhaltung der Funktion bis zu ihrem Anschlag bewegt werden kann.The solution of this object is achieved in conjunction with the preamble features according to the invention by means of the features of the characterizing part of the main claim. Because the scroll spring has at least one recess in the region of its end and a corresponding locking cam is arranged in the housing, the roller spring slides over its functional length over a sliding surface of this locking cam, which engages in the recess only in the region of the end of the scroll spring and so the scroll spring secures against a complete excerpt from the case, on the one hand, a very economical solution is achieved because at the same time the end of the scroll spring and the beginning of the next scroll spring is processed by means of a common tool in the production of the ablated from a spring band scroll spring, so that for the production The recesses no additional step is required and no additional component must be added. On the other hand, it is of particular advantage that the spring can roll up again after releasing a tensile spring, so that it can be moved as often as possible while fully maintaining its function until it stops.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims.

Gemäß einer besonders bevorzugten Variante der Erfindung sind im Gehäuse zwei seitliche Rastnocken im Randbereich der Rollfeder angeordnet, wobei die Rollfeder über ihre Funktionslänge im übrigen eine konstante Breite aufweist und nur im Bereich ihres Endes mit zwei mit den Rastnocken korrespondierenden seitlichen Ausnehmungen versehen ist. Hierdurch wird eine symmetrisch wirkende Auszugssicherung zur Verfügung gestellt und die Betriebssicherheit verdoppelt, wobei eine Version mit einer einzigen mittigen Raste und einer mittigen Ausnehmung ebenso wenig von dem Erfindungsgedanken ausgeschlossen ist, wie eine Ausführungsform mit etwa drei Rasten, von denen eine mittig und zwei randseitig angeordnet sein können.According to a particularly preferred variant of the invention, two lateral locking cams are arranged in the edge region of the scroll spring in the housing, wherein the scroll spring has a constant width over its functional length and only in the region of its end with two corresponding with the locking cams lateral recesses is provided. As a result, a symmetrically acting pull-out protection is provided and the reliability is doubled, with a version with a central notch and a central recess as well as the inventive idea is excluded, as an embodiment with about three notches, one of which centrally and two arranged at the edge could be.

Bevorzugterweise ist die Ausnehmung rechteckig ausgebildet, so dass in Auszugrichtung die hintere Kante der Ausnehmung hinter einem Vorsprung des Rastnockens einrasten kann, so dass eine verhältnismäßig breite Fläche als Anschlagfläche zur Verfügung gestellt werden kann, wodurch insbesondere die Gesamtlebensdauer des Bauteils auf unbegrenzte Zeit verlängert wird.Preferably, the recess is rectangular, so that in the extension direction, the rear edge of the recess can engage behind a projection of the locking cam, so that a relatively wide area can be provided as a stop surface, which in particular the total life of the component is extended indefinitely.

Entsprechend einer weiteren vorteilhaften Ausführungsform der Erfindung ist der oder sind die Rastnocken im Bereich des Austrittsspaltes der Rollfeder aus dem Gehäuse angeordnet oder im unteren Bereich der vorderen Stirnwand des Gehäuses, insbesondere aber bei einer besonders bevorzugten Ausgestaltung der Erfindung jeweils gleichzeitig im Bereich des Auszugsspaltes sowie im unteren Bereich der vorderen Stirnwand, so dass für unterschiedliche Lagerungsarten der Rollfeder im Gehäuse keine unterschiedlichen Gehäusebauformen bereitgehalten werden müssen, sondern je nach verwendeter Lagerung der Rollfeder die einen oder anderen Rastnocken automatisch in Funktion treten.According to a further advantageous embodiment of the invention, the locking cam or in the region of the exit slit of the scroll spring from the housing or in the lower region of the front end wall of the housing, but in particular in a particularly preferred embodiment of the invention in each case simultaneously in the region of the separation gap and in lower portion of the front end wall, so that no different housing designs must be kept ready for different types of storage of the scroll spring in the housing, but depending on the used storage of the spring roll one or the other locking cams automatically come into operation.

Die Rastnocken im Bereich des Austrittsspaltes treten bei einer Ausführungsform in Funktion, bei der die Rollfeder auf einer tonnenförmigen Drehachse gelagert ist, welche ortsfest im Gehäuse angeordnet ist. Die Rastnocken im unteren Bereich der vorderen Stirnseite treten bei einer Rollfeder in Aktion, die nur von den Seitenwänden des Gehäuses seitlich gleitgelagert ist, so dass sich ihr Durchmesser bei steigendem Auszug verringert und sich das restliche Federpaket in der unteren vorderen Ecke des Gehäuses an der vorderen Stirnseite abstützt, weswegen dort auch die Rastnocken angeordnet sind. Bevorzugterweise sind die Gleitflächen der Rastnocken und auch die innere Stirnseite des Gehäuses zumindest teilweise mit einem besonders gleitfähigen Material ausgestattet.The locking cams in the region of the outlet gap come into effect in an embodiment in which the roll spring is mounted on a barrel-shaped axis of rotation, which is arranged stationarily in the housing. The locking cams in the lower region of the front end occur in a roll spring in action, which is laterally slidably supported only by the side walls of the housing so that its diameter decreases with increasing extract and the remaining spring assembly in the lower front corner of the housing at the front End side supported, which is why there are arranged the locking cams. Preferably, the sliding surfaces of the locking cams and also the inner end face of the housing at least partially equipped with a particularly lubricious material.

Die erfinderische Auszugssicherung einer Rollfeder aus einem Gehäuse eignet sich besonders zur Verwirklichung eines funktionssicheren Warenvorschubgehäuses einer Warenpräsentationsvorrichtung.The inventive pull-out protection of a scroll spring from a housing is particularly suitable for the realization of a functionally reliable goods feed housing a goods presentation device.

Die Auszugssicherung einer Rollfeder 1 aus einem Gehäuse 3 wird anhand eines Warenvorschubgehäuses eines Warenpräsentationssystems beschrieben.The extract safety of a roll spring 1 from a housing 3 is described with reference to a goods feed housing of a goods presentation system.

Das Gehäuse 3 besteht aus Kunststoff, ist nach hinten offen und weist nach vorne eine als Schubplatte ausgebildete Stirnwand 9 auf, an deren Innenseite zwei Streifen eines hochgleitfähigen Materials als Gleitlager 10 angeordnet sind. Unterhalb der Stirnwand 9 befindet sich der Austrittsspalt 8, aus dem die Rollfeder 1 etwa horizontal austritt. Im unteren Bereich der Stirnwand 9, oberhalb einer etwa horizontalen Innenwandung des Gehäuses 3, sind innenliegend beidseitig zwei etwa unterlegkeilförmige Rastnocken 4 so angeordnet, dass eine zylindrisch aufgewickelte Rollfeder 1, deren Durchmesser bei vergrößertem Auszug aus dem Gehäuse 3 kontinuierlich abnimmt, kurz vor einem Vollauszug mit ihren seitlich in die Rollfeder 1 eingebrachten Ausnehmungen 2 hinter einem Vorsprung 7 der Rastnocke 4 verrasten, wohingegen nach Entlastung der Rollfeder 1 diese entgegengesetzt auf der Gleitfläche 5 der Rastnocke zurückgleitet, so dass sich die Rollfeder 1 wieder vollständig aufwickeln kann.The housing 3 is made of plastic, is open to the rear and has forward as a thrust plate formed end wall 9, on the inside of two strips of highly lubricious material are arranged as a sliding bearing 10. Below the end wall 9 is the exit slit 8 from which the scroll spring 1 emerges approximately horizontally. In the lower region of the end wall 9, above an approximately horizontal inner wall of the housing 3, two about unterlegkeilförmige locking cams 4 are arranged on both sides so that a cylindrically wound spring roll 1, the diameter of which in an enlarged excerpt from the housing 3 continuously decreasing, shortly before a full extension with their recesses 2 introduced laterally into the spring 1 lock behind a projection 7 of the locking cam 4, whereas after relieving the spring 1 this slides back oppositely on the sliding surface 5 of the locking cam, so that the scroll spring 1 completely rewind can.

Das Endstück 16 der Rollfeder 1 ist dabei schmaler ausgeführt als der freie Raum zwischen den Rastnocken 4 breit ist und weist eine Länge auf, die etwa dem Umfang einer ersten Wicklung entspricht.The tail 16 of the scroll spring 1 is made narrower than the free space between the locking cam 4 is wide and has a length which corresponds approximately to the circumference of a first winding.

Wie in den Figuren 4 und 5 dargestellt, sind zwei Rastnocken 14 im Bereich des unteren Austrittsspaltes 8 des Gehäuses 3 angeordnet, wobei der Auszugsspalt etwa waagerecht bzw. etwa tangential zu einer nicht ausgezogenen Rollfeder 1 ausgerichtet ist, so dass diese Rollfeder 1 während des Auszuges über vordere Gleitflächen 15 der Rastnocke 14 hinweggleitet. Ein zunehmender Auszug der Rollfeder 1 bewirkt eine Durchmesserreduzierung des restlichen Federpaketes, wodurch sich der Winkel zwischen Austrittsspalt 8 und der Drehachse 11 der Rollfeder 1 verstärkt, sodass kurz vor dem Volllauszug der Rollfeder 1 die hintere Kante 6 der Ausnehmung 2 der Rollfeder 1 hinter den Vorsprung 17 der Rastnocke 14 greift und einen Vollauszug der Rollfeder 1 verhindert.As in the FIGS. 4 and 5 shown, two locking cams 14 are arranged in the region of the lower exit gap 8 of the housing 3, wherein the pull-out gap is oriented approximately horizontally or approximately tangentially to a non-extended scroll spring 1, so that this scroll spring 1 during the extension via front sliding surfaces 15 of the latching cam 14th glides. An increasing excerpt of the scroll spring 1 causes a reduction in diameter of the remaining spring assembly, whereby the angle between the exit slit 8 and the axis of rotation 11 of the scroll spring 1 amplified, so shortly before the full release of the scroll spring 1, the rear edge 6 of the recess 2 of the scroll spring 1 behind the projection 17 of the locking cam 14 engages and prevents a full extension of the scroll spring 1.

Bei Entlastung der Rollfeder 1 wird diese über die Gleitfläche 15 zurückbewegt und kann sich frei um die Drehachse 11 zurück aufwickelnWhen relief of the scroll spring 1, this is moved back over the sliding surface 15 and can freely rewind around the axis of rotation 11 back

Die Gleitflächen 5 und 15 der Rastnocken 4;14 können mit einem besonders gleitfähigen Material beschichtet sein oder selber daraus bestehen.The sliding surfaces 5 and 15 of the locking cams 4, 14 may be coated with a particularly lubricious material or may itself consist thereof.

In den seitlichen Wänden des Gehäuses 3 ist einen Aufnahme 12 eingeformt, in die bei Bedarf die tonnenförmige Drehachse 11 von hinten frei einsetzbar ist, wie dies in der Fig. 4 dargestellt ist, die das Endstück 16 in einer gerade ausgestreckten Lage zeigt, welches sich jedoch tatsächlich um die Drehachse 11 herumwindet.In the lateral walls of the housing 3, a receptacle 12 is formed, in which, if necessary, the barrel-shaped axis of rotation 11 is freely usable from behind, as shown in the Fig. 4 is shown, which shows the end piece 16 in a straight extended position, but which actually wraps around the axis of rotation 11.
