  • the grids or webs forming the carrier plate are therefore not dimensionally stable and are warped in particular when the temperature rises.
  • the Carrier plate of the aforementioned type is to be used in dishwashers in which the temperature is only about 60 ° C. As a result, such a carrier plate cannot be used in applications in which the medium temperature is above 100 ° C.
  • High-precision components made of metal are inserted into the connector body in order to store and clean them. Temperatures of approx. 120 ° C and more prevail during the cleaning process and the cleaning media, in particular water with cleaning solutions, strike the carrier plate directly.
  • the carrier arrangement known from the aforementioned prior art cannot be used for such high-quality precision components, since the connection between the carrier plate and the objects to be cleaned has play due to the clamping fixation of the fastening base in the respective receiving openings, so that the fastening base corresponding forces transmitted by the medium wobble and consequently the objects connected to the mounting base could hit each other.

  • the wire strands are disadvantageously made of a metallic material, which ensures that there is no distortion under the influence of temperature and the lattice-shaped support frame is dimensionally stable, but the manufacturing costs for such support frames are enormously high, since on the one hand they are formed from wire strands which are time-consuming Interconnections are to be connected.
  • the adjacent receiving openings which are laterally adjacent to an already used receiving opening, cannot be used for further connecting bodies, since the connecting body already used overlaps the wire strands and these are therefore no longer free for adjacent fixings of connecting bodies. This means that a significant number of receiving openings must be left free and the cleaning process is not sufficiently optimized since many of the places at the receiving openings are unoccupied.

  • Such a latching of the holding base on the projections can be brought about quickly and, if necessary, can also be released again without being destroyed.
  • the type of fastening according to the invention between the holding base and the projections provided in the receiving openings means that any size of connecting bodies can be used, provided that the respective holding base is configured identically. Consequently, connecting bodies can also be used, the bottom of which is configured to be substantially larger than the edge length of the receiving opening.
  • the connecting body should namely be as identical as possible to the outer circumference of the object used in order to prevent the object from wobbling in the connecting body and possibly touching an adjacent object and causing damage as a result of this contact.
  • an arbitrary edge length can be provided for the receiving opening, because the length of the projection can be adapted to the edge length. Nevertheless, the respective holding base can then be locked on two opposite projections, because the holding base can still be inserted between the laterally offset projections and can be connected to the projections by twisting in the direction of the projections.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Aufnahme und Arretierung von Gegenständen an einem Traggestell gemäß des Oberbegriffes von Patentanspruch 1 sowie auf ein Traggestell zur Anwendung in einer solchen Vorrichtung gemäß des Oberbegriffes von Patentanspruch 6.The invention relates to a device for receiving and locking objects on a support frame according to the preamble of claim 1 and to a support frame for use in such a device according to the preamble of claim 6.

Aus der AT 14 852 U1 ist eine Trägeranordnung für die Lagerung und/oder den Transport und/oder die Reinigung von Geschirr oder anderen Gegenständen beschrieben. Die Trägeranordnung besteht dabei aus einer Trägerplatte mit mindestens einer gitterförmigen Struktur, die von quadratischen Öffnungen gebildet ist. In jede der Aufnahmeöffnungen kann ein Befestigungssockel eingesetzt werden, der eine Außenkontur aufweist, durch die eine klemmende oder formschlüssige Verbindung in Form eines Gewindes vorhanden ist und die mit der Innenkontur der jeweiligen Aufnahmeöffnungen derart zusammenwirkt, dass der Befestigungssockel in der jeweiligen Aufnahmeöffnung lageorientiert gehalten ist.From the AT 14 852 U1 describes a carrier arrangement for the storage and / or transport and / or cleaning of dishes or other objects. The carrier arrangement consists of a carrier plate with at least one lattice-shaped structure which is formed by square openings. A mounting base can be inserted into each of the mounting openings, which has an outer contour, through which a clamping or form-fitting connection is provided in the form of a thread and which interacts with the inner contour of the respective mounting openings in such a way that the mounting base is held in a position-oriented manner in the respective mounting opening.

Als nachteilig bei der Ausgestaltung der Trägerplatte hat sich herausgestellt, dass diese bei Temperaturerhöhungen einem erheblichen Verschleiß unterworfen ist, denn die Trägerplatte ist aus einem Kunststoff-Werkstoff hergestellt und die Breite der die Aufnahmeöffnungen einschließenden Stege der Trägerplatte sind bezogen auf die Wandstärke der Stege in einem Verhältnis ausgestaltet, durch das ein Verzug der jeweiligen Stege entsteht, wenn entsprechende Gravitationskräfte auf die Trägerplatte einwirken. Die die Trägerplatte bildenden Gitter oder Stege sind demnach nicht formstabil und werden insbesondere bei Temperaturerhöhungen verzogen. Die Trägerplatte der vorgenannten Gattung soll in Geschirrspülmaschinen eingesetzt werden, in denen lediglich eine Temperatur von ca. 60 °C herrscht. Folglich kann eine solche Trägerplatte in Anwendungen nicht eingesetzt werden, bei denen eine Mediumstemperatur von über 100 °C vorherrscht. Hochpräzisionsbauteile aus Metall werden in den Verbindungkörper eingesetzt, um diese zu lagern und reinigen zu können. Während des Reinigungsvorganges herrschen Temperaturen von ca. 120 °C und mehr und die Reinigungsmedien, insbesondere Wasser mit Reinigungslösungen, treffen unmittelbar auf die Trägerplatte auf.It has been found to be disadvantageous in the configuration of the carrier plate that it is subject to considerable wear when the temperature rises, because the carrier plate is made of a plastic material and the width of the webs of the carrier plate enclosing the receiving openings are related to the wall thickness of the webs in one Relationship designed by which a distortion of the respective webs arises when corresponding gravitational forces act on the carrier plate. The grids or webs forming the carrier plate are therefore not dimensionally stable and are warped in particular when the temperature rises. The Carrier plate of the aforementioned type is to be used in dishwashers in which the temperature is only about 60 ° C. As a result, such a carrier plate cannot be used in applications in which the medium temperature is above 100 ° C. High-precision components made of metal are inserted into the connector body in order to store and clean them. Temperatures of approx. 120 ° C and more prevail during the cleaning process and the cleaning media, in particular water with cleaning solutions, strike the carrier plate directly.

Zudem kann die aus dem vorgenannten Stand der Technik bekannt gewordene Trägeranordnung für solche hochwertigen Präzisionsbauteile nicht verwendet werden, da die Verbindung zwischen der Trägerplatte und den zu reinigenden Gegenständen aufgrund der klemmenden Fixierung des Befestigungssockels in den jeweiligen Aufnahmeöffnungen ein Spiel aufweist, so dass der Befestigungssockel bei entsprechenden durch das Medium übertragene Kräfte wackelt und folglich die mit dem Befestigungssockel verbundenen Gegenstände aneinander schlagen könnten. In Geschirrspülmaschinen ist ausreichend Bauraum bzw. Platz vorhanden und geringe Berührungen zwischen den eingelagerten Gegenstände in der Spülmaschine führen nicht notwendigerweise zu Beschädigungen bzw. das zu reinigende Geschirr wird nicht beschädigt, wenn dieses sich berührt oder gegeneinander trifft. Zudem kann die Klemmverbindung zwischen den Befestigungssockel und der Aufnahmeöffnung verloren gehen, wenn nämlich die Temperaturen des Mediums derart hoch sind, dass zwischen diesen ein Spiel oder Luftspalt entsteht.In addition, the carrier arrangement known from the aforementioned prior art cannot be used for such high-quality precision components, since the connection between the carrier plate and the objects to be cleaned has play due to the clamping fixation of the fastening base in the respective receiving openings, so that the fastening base corresponding forces transmitted by the medium wobble and consequently the objects connected to the mounting base could hit each other. Sufficient installation space or space is available in dishwashers and slight contact between the stored objects in the dishwasher does not necessarily lead to damage or the dishes to be cleaned are not damaged when they touch or hit one another. In addition, the clamping connection between the mounting base and the receiving opening can be lost, namely when the temperatures of the medium are so high that there is a play or air gap between them.

Die Patentanmelderin hat diese Problematik erkannt und in der jüngeren Vergangenheit Lösungen entwickelt, durch die dieses Problem zur Abstützung der hochwertigen Präzisionsbauteile während des Reinigungsvorganges vermieden werden soll. Beispielsweise aus der EP 2 860 126 A1 ist eine Vorrichtung zur Aufnahme und Arretierung von Gegenständen bekannt geworden, die ein Drahtgestell aufweist, dass aus Drahtstäengen die parallel bzw. senkrecht zueinander verlaufen gebildet ist. Dabei sind die jeweils parallel verlaufenden Drahtstränge in einer Ebene angeordnet und die die andere Ebene bildenden Drahtstränge verlaufen unterhalb dieser Ebene, sodass die senkrecht zueinander verlaufenden Drahtstränge als Befestigungshilfe für einen in die jeweilige Aufnahmeöffnung einsetzbaren Haltesockel benutzt werden kann. In den Haltesockel eines Verbindungskörpers sind demnach zwei Klemmnuten eingearbeitet die in unterschiedlichen Ebenen verlaufen. Dabei sind zwei gegenüberliegende Klemmnuten jeweils den parallel verlaufenden Drahtstränge einer der Ebenen der Aufnahmeöffnung zugeordnet. Durch Verdrehen des Verbindungskörpers innerhalb der Aufnahmeöffnung kann somit eine Arretierung zwischen dem Haltesockel und den die Aufnahmeöffnung umschließenden Drahtsträngen geschaffen werden, so dass der Verbindungskörper lageorientierten in der jeweiligen Aufnahmeöffnung bzw. an den Drahtsträngen gehalten ist. Der Boden des Verbindungskörpers dient dabei als Anschlagshilfe.The patent applicant has recognized this problem and, in the recent past, has developed solutions to avoid this problem for supporting the high-quality precision components during the cleaning process. For example from the EP 2 860 126 A1 has become known a device for receiving and locking objects, which has a wire frame that is formed from wire rods that run parallel or perpendicular to each other. The respective parallel wire strands are arranged in one plane and the wire strands forming the other plane run below this level, so that the wire strands running perpendicular to one another are used as a fastening aid for a holding base which can be inserted into the respective receiving opening can. Accordingly, two clamping grooves are incorporated in the holding base of a connecting body and run in different planes. Two opposing clamping grooves are each assigned to the parallel wire strands of one of the levels of the receiving opening. By rotating the connecting body within the receiving opening, a locking can thus be created between the holding base and the wire strands surrounding the receiving opening, so that the connecting body is held in a position-oriented manner in the respective receiving opening or on the wire strands. The bottom of the connecting body serves as a stop aid.

Die Drahtstränge sind nachteiligerweise aus einem metallischen Werkstoff herzustellen, der zwar gewährleistet, dass bei entsprechenden Temperatureinwirkungen kein Verzug entsteht und das gitterförmige Traggestell formstabil ist, jedoch sind die Herstellungskosten für solche Traggestelle enorm hoch, da diese zum einen aus Drahtsträngen gebildet sind, die zeitaufwendig in Knotenpunkten miteinander zu verbinden sind.The wire strands are disadvantageously made of a metallic material, which ensures that there is no distortion under the influence of temperature and the lattice-shaped support frame is dimensionally stable, but the manufacturing costs for such support frames are enormously high, since on the one hand they are formed from wire strands which are time-consuming Interconnections are to be connected.

Außerdem können die benachbarten Aufnahmeöffnungen, die seitlich neben einer bereits benutzten Aufnahmeöffnung liegen, für weitere Verbindungkörper nicht verwendet werden, da der bereits eingesetzte Verbindungskörper die Drahtstränge überlappt und diese folglich für benachbarte Fixierungen von Verbindungskörpern nicht mehr frei sind. Somit ist eine erhebliche Anzahl von Aufnahmeöffnungen freizulassen und der Reinigungsvorgang ist nicht ausreichend optimiert, da viele der Plätze an den Aufnahmeöffnungen unbelegt sind.In addition, the adjacent receiving openings, which are laterally adjacent to an already used receiving opening, cannot be used for further connecting bodies, since the connecting body already used overlaps the wire strands and these are therefore no longer free for adjacent fixings of connecting bodies. This means that a significant number of receiving openings must be left free and the cleaning process is not sufficiently optimized since many of the places at the receiving openings are unoccupied.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung zur Aufnahme und Arretierung von Gegenständen sowie ein Traggestell für eine solche Vorrichtung zur Verfügung zu stellen, die zum einen kostengünstig und schnell herstellbar ist, und durch die zum anderen der Reinigungsvorgang, insbesondere für hochwertige Präzisionsbauteile, mit einer ausreichenden Reinigungstemperatur optimiert ist, ohne dass durch die Temperatureinwirkungen die Vorrichtung und insbesondere das Traggestell der Vorrichtung einem Verzug oder Verschleiß unterworfen sind.It is therefore an object of the invention to provide a device for receiving and locking objects and a support frame for such a device, which is inexpensive and quick to manufacture on the one hand, and on the other hand with the cleaning process, in particular for high-quality precision components a sufficient cleaning temperature is optimized without the device and in particular the supporting frame of the device being subjected to warping or wear due to the effects of temperature.

Zudem sollten die Verbindungskörper unabhängig von ihrer Bauraumgröße an Traggestellen montierbar sein, deren Aufnahmeöffnung unterschiedlich groß bemessene Kantenlänge ausweisen.In addition, regardless of their installation space size, the connecting bodies should be mountable on supporting frames, the receiving openings of which have edge lengths of different sizes.

Diese Aufgabe ist erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 sowie durch die Merkmale des kennzeichnenden Teils von Patentanspruch 6 gelöst.This object is achieved according to the invention by the features of the characterizing part of patent claim 1 and by the features of the characterizing part of patent claim 6.

Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention result from the subclaims.

Durch die kennzeichnenden Merkmale der Patentansprüche 1 und 6 wird erreicht, dass zum einen die Vorrichtung auch bei hohen Temperatureinflüssen von mehr als 100 °C aus einem formstabilen Traggestell gebildet ist, dass zum anderen die Gegenstände an dem Traggestell gehalten sind und dass zudem das Traggestell kostengünstig im Kunststoff-Spritzgussverfahren herstellbar ist und dessen Struktur auch nach einer Vielzahl von Temperaturerhöhungen aufgrund von Reinigungsmitteln ohne Verzug ist, da die Stege des Traggestelles insbesondere in Gravitationsrichtung eine erhebliche Breite aufweisen, die dem Verzug aufgrund von Temperaturschwankungen entgegenwirkt.The characterizing features of claims 1 and 6 ensure that, on the one hand, the device is formed from a dimensionally stable support frame even at high temperature influences of more than 100 ° C., that, on the other hand, the objects are held on the support frame and that the support frame is also inexpensive can be produced by plastic injection molding and the structure of which, even after a large number of temperature increases due to cleaning agents, is not distorted, since the webs of the supporting frame have a considerable width, particularly in the direction of gravity, which counteracts the delay due to temperature fluctuations.

Zudem kann die jeweilige Aufnahmeöffnung als Quadrat ausgestaltet sein, so dass in dem Traggestell eine optimale Anzahl von Aufnahmeöffnungen vorgesehen werden kann und da jede Aufnahmeöffnung mit einem Verbindungkörper betätigt werden kann, ist der von dem Traggestell zur Verfügung gestellte Platz optimal ausgenutzt, denn jede Aufnahmeöffnung ist belegbar. Folglich können eine Vielzahl von Gegenständen gereinigt werden, ohne dass Platz an dem Traggestell ungenutzt bleibt.In addition, the respective receiving opening can be designed as a square, so that an optimal number of receiving openings can be provided in the support frame and since each receiving opening can be actuated with a connecting body the space provided by the support frame is optimally used, because every opening can be occupied. As a result, a variety of items can be cleaned without wasting space on the support frame.

Darüber hinaus kann das eingesetzte Reinigungsmittel die jeweiligen Traggestelle, die oftmals gestapelt übereinander angeordnet sind, optimal durchströmen, so dass das Reinigungsmittel in Gravitationsrichtung schnell und in ausreichenden Mengen strömen kann, da die Durchmesser bzw. Kantenlängen der Aufnahmeöffnungen im Verhältnis wesentlich größer bemessen sind als die Wandstärke der Stege. Folglich benötigen die Stege eine wesentlich geringere Fläche als die von der jeweiligen Aufnahmeöffnung freigegebenen Fläche ausgestaltet werden kann.In addition, the cleaning agent used can flow optimally through the respective support frames, which are often stacked one above the other, so that the cleaning agent can flow quickly and in sufficient quantities in the direction of gravity, since the diameters or edge lengths of the receiving openings are proportionately larger than that Wall thickness of the webs. As a result, the webs require a much smaller area than the area released by the respective receiving opening.

Die Befestigung der jeweiligen Haltesockel an den Stegen erfolgt dadurch, dass an diesen zwei gegenüberliegende Vorsprünge angebracht oder vorgesehen sind, die bezogen auf die Symmetrieachse der Aufnahmeöffnungen seitlich versetzt zueinander angeordnet sind. Somit kann der Haltesockel des jeweiligen Verbindungskörpers verdreht in die Aufnahmeöffnung eingesteckt sein und sobald der Boden des Verbindungskörpers auf der Oberseite des Traggestells aufliegt, kann der Haltesockel in die jeweilige Richtung zu dem Vorsprung gedreht sein, so dass die in den Haltesockel eingearbeiteten und gegenüberliegend verlaufenden Klemmnuten mit dem jeweiligen Vorsprung zusammenwirken und nach Art einer Hinterschneidung den Vorsprung umgreift, wodurch der Haltesockel lageorientiert an den beiden Vorsprüngen fixiert ist. Eine solche Verrastung des Haltesockels an den Vorsprüngen kann schnell herbeigeführt und gegebenenfalls auch wieder zerstörungsfrei gelöst werden.The respective holding base is attached to the webs by attaching or providing two opposite projections, which are laterally offset with respect to one another with respect to the axis of symmetry of the receiving openings. Thus, the holding base of the respective connecting body can be inserted twisted into the receiving opening and as soon as the bottom of the connecting body rests on the upper side of the supporting frame, the holding base can be turned in the respective direction to the projection, so that the clamping grooves worked into the holding base and running in opposite directions cooperate with the respective projection and engages around the projection in the manner of an undercut, as a result of which the holding base is fixed to the two projections in a position-oriented manner. Such a latching of the holding base on the projections can be brought about quickly and, if necessary, can also be released again without being destroyed.

Ferner beinhaltet die erfindungsgemäße Befestigungsart zwischen dem Haltesockel und den in den Aufnahmeöffnungen vorgesehenen Vorsprüngen, dass eine beliebige Größe von Verbindungskörpern verwendet werden kann unter der Voraussetzung, dass der jeweilige Haltesockel identisch ausgestaltet ist. Folglich können auch Verbindungskörpers eingesetzt werden, deren Boden wesentlich größer ausgestaltet ist als die Kantenlänge der Aufnahmeöffnung. Der Verbindungskörper soll nämlich möglichst identisch mit dem Außenumfang des eingesetzten Gegenstandes sein, um zu verhindern, dass der Gegenstand in dem Verbindungskörper wackelt und möglicherweise einen benachbarten Gegenstand berührt und Beschädigungen aufgrund dieser Berührung entstehen.Furthermore, the type of fastening according to the invention between the holding base and the projections provided in the receiving openings means that any size of connecting bodies can be used, provided that the respective holding base is configured identically. Consequently, connecting bodies can also be used, the bottom of which is configured to be substantially larger than the edge length of the receiving opening. The connecting body should namely be as identical as possible to the outer circumference of the object used in order to prevent the object from wobbling in the connecting body and possibly touching an adjacent object and causing damage as a result of this contact.

Des Weiteren kann eine beliebige Kantenlänge für die Aufnahmeöffnung vorgesehen werden, denn die Länge des Vorsprungs kann an die Kantenlänge angepasst werden. Gleichwohl kann dann der jeweilige Haltesockel an zwei gegenüberliegenden Vorsprüngen arretiert sein, denn der Haltesockel ist nach wie vor zwischen die seitlich versetzt zueinander verlaufenden Vorsprüngen einsetzbar und durch Verdrehen in Richtung der Vorsprünge mit diesen verbindbar. Je länger die Kantenlänge der Aufnahmeöffnung, desto länger ist auch der jeweilige Vorsprung und umgekehrt auszubilden.Furthermore, an arbitrary edge length can be provided for the receiving opening, because the length of the projection can be adapted to the edge length. Nevertheless, the respective holding base can then be locked on two opposite projections, because the holding base can still be inserted between the laterally offset projections and can be connected to the projections by twisting in the direction of the projections. The longer the edge length of the receiving opening, the longer the respective projection and vice versa.

In the drawing, a device is shown, which is explained in more detail below. In detail shows:

Aus Figur 1 ist ersichtlich, dass eine Vorrichtung 1 zur Verfügung gestellt werden soll, durch die eine Vielzahl von Verbindungskörpern 2 an einem Traggestell 4 befestigbar sind. Durch den jeweiligen Verbindungskörper 2 soll ein Gegenstand 3, beispielsweise ein Werkstück als Hochpräzisionsbauteil, gehalten sein, um diese Gegenstände 3 sicher zu lagern, transportieren und reinigen zu können.Out Figure 1 it can be seen that a device 1 is to be made available, by means of which a multiplicity of connecting bodies 2 can be fastened to a supporting frame 4. The respective connecting body 2 is intended to hold an object 3, for example a workpiece as a high-precision component, in order to be able to store, transport and clean these objects 3 safely.

Das Traggestell 4 wird von Stegen 7, 8 gebildet, die paarweise parallel zueinander verlaufen. Folglich bilden jeweils zwei Paare der Stege 7, 8 eine der Aufnahmeöffnung 9, denn die Stege 7, 8 stehen senkrecht zueinander. Die Kantenlänge der Aufnahmeöffnung 9 ist dabei identisch, so dass eine quadratische Aufnahmeöffnung 9 entsteht.The support frame 4 is formed by webs 7, 8, which run in pairs parallel to each other. Consequently, two pairs of the webs 7, 8 each form one of the receiving openings 9, because the webs 7, 8 are perpendicular to one another. The edge length of the receiving opening 9 is identical, so that a square receiving opening 9 is created.

In den Eckbereichen des Traggestells 4 sind Bohrungen oder Durchgangsöffnungen vorgesehen in denen Abstandhalter einsetzbar sind, um eine Vielzahl von Traggestellen 4 übereinander stapeln zu können.In the corner areas of the support frame 4, holes or through openings are provided in which spacers can be used in order to be able to stack a plurality of support frames 4 one above the other.

An dem Verbindungskörper 2 ist ein runder Boden 10 vorgesehen, an dessen eine Stirnseite ein rechteckförmiger Halssockel 11 und auf der gegenüberliegenden Stirnseite ein oder mehrere Halte- oder Aufnahmeelemente 12 vorgesehen sind, die einen Raum einschließen, in dem der jeweilige Gegenstand 3 abgelegt werden kann. Der Haltesockel 11 kann in eine der Aufnahmeöffnungen 9 - wie dies nachfolgend noch näher erläutert wird - eingesetzt und lageorientiert mit dem Traggestell 4 fixiert werden. Der Haltesockel 11 verläuft dabei fluchtend zu der Längsachse 6 des jeweiligen Verbindungskörpers 2.A round base 10 is provided on the connecting body 2, on the one end side of which a rectangular neck base 11 and on the opposite end side one or more holding or receiving elements 12 are provided, which enclose a space in which the respective object 3 can be stored. The holding base 11 can be inserted into one of the receiving openings 9 - as will be explained in more detail below - and fixed in a position-oriented manner with the support frame 4. The holding base 11 runs in alignment with the longitudinal axis 6 of the respective connecting body 2.

Der Boden 10 des Verbindungskörpers 2 weist einen Durchmesser auf, der in etwa der Kantenlänge der Aufnahmeöffnung 9 entspricht, so dass die dem Traggestell 4 zugewandte Unterseite des Bodens 10 auf der Oberseite 5 des Traggestells 4 aufliegt und von den Stegen 7, 8 abgestützt ist. Alternativ kann an zwei gegenüberliegenden Stegen 7, 8 auch jeweils eine Auflagenase 24 angeformt oder vorgesehen sein, die in das Zentrum 13 der jeweiligen Aufnahmeöffnung 9 ragt und als Anschlag für den einzusetzenden Haltesockel 11 des Verbindungskörpers 2 dient, so dass auch Verbindungskörper 2 mit einem kleineren Durchmesser des Bodens 10 als die Kantenlänge zuverlässig auf der Oberseite 5 des Traggestells 4 abgestützt sind.The bottom 10 of the connecting body 2 has a diameter which corresponds approximately to the edge length of the receiving opening 9, so that the underside of the bottom 10 facing the supporting frame 4 rests on the upper side 5 of the supporting frame 4 and is supported by the webs 7, 8. Alternatively, a support lug 24 can also be formed or provided on two opposite webs 7, 8 be, which protrudes into the center 13 of the respective receiving opening 9 and serves as a stop for the holding base 11 to be used of the connecting body 2, so that connecting bodies 2 with a smaller diameter of the base 10 than the edge length are also reliably supported on the upper side 5 of the supporting frame 4 .

Eine parallel zu den Stegen 7, 8 verlaufende Symmetrieachse entlang einer der Reihen von Aufnahmeöffnungen 9 ist mit der Bezugsziffer 14 gekennzeichnet und dient als Bezug für die Anordnung von Vorsprüngen 21, 22.An axis of symmetry running parallel to the webs 7, 8 along one of the rows of receiving openings 9 is identified by the reference number 14 and serves as a reference for the arrangement of projections 21, 22.

Figur 2 ist zu entnehmen, wie der Haltesockel 11 des Aufnahmekörpers 2 ausgestaltet ist und in der jeweiligen Aufnahmeöffnung 9 des Traggestelles 4 arretierbar ist. Der Haltesockel 11 weist nämlich eine rechteckförmige Außenkontur mit vier Kantenlängen 16, 17, 18 und 19 auf. An den längeren Kantenlängen 18, 19 sind Klemmnuten 15 eingearbeitet, die in ihrem Querschnitt gemeinsam mit der Unterseite des Bodens 10 eine U-förmige Innenkontur bilden. Die beiden kürzer bemessenen Längskanten 16, 17 zwischen den Klemmnuten 15 sind plan ausgestaltet. Die dazu senkrecht verlaufenden Längskanten 18, 19 tragen die Klemmnuten 15. Ferner sind die gegenüberliegenden Klemmnuten 15 spiegelbildend zueinander versetzt angeordnet. Figure 2 it can be seen how the holding base 11 of the receiving body 2 is designed and can be locked in the respective receiving opening 9 of the supporting frame 4. The holding base 11 namely has a rectangular outer contour with four edge lengths 16, 17, 18 and 19. Clamping grooves 15 are incorporated into the longer edge lengths 18, 19, which together with their underside of the base 10 form a U-shaped inner contour in their cross section. The two shorter longitudinal edges 16, 17 between the clamping grooves 15 are flat. The longitudinal edges 18, 19 which run perpendicularly thereto carry the clamping grooves 15. Furthermore, the opposing clamping grooves 15 are staggered to form a mirror image.

An der jeweiligen Seitenwand der Stege 7 ist jeweils ein Vorsprung 21, 22 angeformt oder vorgesehen, die plattenförmig ausgestaltet sind. Die Vorsprünge 21, 22 ragen demnach in das Zentrum 13 der jeweiligen Aufnahmeöffnung 9 und sind von der Oberseite 5 des Traggestells 4 beabstandet. Die Vorsprünge 21, 22 verlaufen in einer gemeinsamen Ebene und stehen senkrecht von dem Steg 7 ab.A projection 21, 22 is formed or provided on the respective side wall of the webs 7, which are designed in the form of a plate. The projections 21, 22 accordingly protrude into the center 13 of the respective receiving opening 9 and are spaced apart from the upper side 5 of the supporting frame 4. The projections 21, 22 run in a common plane and project perpendicularly from the web 7.

Darüber hinaus sind die beiden in einer der Aufnahmeöffnung 9 vorhandenen Vorsprünge 21, 22 bezogen auf die Symmetrieachse 14 spiegelbildlich versetzt zueinander angeordnet. Der Vorsprung 21 weist einen Versatz V auf, der rechts von der Symmetrieachse 14 verläuft und der Vorsprung 22 weist einen Versatz V auf, der links von der Symmetrieachse 14 verläuft. Betragsmäßig ist der Versatz V beider Vorsprünge 21, 22 zu der Symmetrieachse 14 identisch. Die geometrischen Abmessungen der Vorsprünge 21, 22 sind ebenso identisch.In addition, the two projections 21, 22 present in one of the receiving openings 9 are arranged in a mirror-inverted manner relative to one another with respect to the axis of symmetry 14. The projection 21 has an offset V that runs to the right of the axis of symmetry 14 and the projection 22 has an offset V that runs to the left of the axis of symmetry 14. The amount V of the two projections 21, 22 to the axis of symmetry 14 is identical. The geometric dimensions of the projections 21, 22 are also identical.

Der diagonale Abstand zwischen zwei Ecken der Vorsprünge 21, 22 entspricht dabei in etwa der Länge der kürzeren, plan ausgestalteten Längskanten 18, 19 des Haltesockels 11, so dass dieser zwischen den Vorsprüngen 21, 22 eintauchen kann, solange bis der Boden 10 auf der Oberseite 5 auftrifft. Dann verlaufen die beiden Klemmnuten 15 des Haltesockels 11 in der von den Vorsprüngen 21, 22 gebildeten Ebene.The diagonal distance between two corners of the projections 21, 22 corresponds approximately to the length of the shorter, flat-shaped longitudinal edges 18, 19 of the holding base 11, so that it can be immersed between the projections 21, 22 until the bottom 10 on the top 5 hits. Then the two clamping grooves 15 of the holding base 11 run in the plane formed by the projections 21, 22.

Folglich kann der Haltesockel 11 des jeweiligen Verbindungskörper 2 in die Aufnahmeöffnung 9 eingeschoben und dort zunächst platziert sein, bis der Boden 10 auf der Oberseite 5 des Traggestells 4 und/oder den Auflagenasen 24 aufliegt. Die beiden Klemmnuten 15 verlaufen dabei in der von den Vorsprüngen 21, 22 gleichen Ebene und die Innenkontur der Klemmnuten 15 ist an die Außenkontur der Vorsprünge 21, 22 angepasst. Sobald der Haltesockel 11 in der Aufnahmeöffnung 9 eingesetzt ist, kann der Verbindungskörper 2 um etwa 45° verdreht werden, so dass die Klemmnuten 15 in Richtung des jeweiligen Vorsprunges 21, 22 bewegbar ist. Somit entsteht eine Arretierung des Haltesockels 11 an den beiden Vorsprüngen 21, 22 nach Art einer Hinterschneidung, da die Klemmnuten 15 im montierten Zustand des Haltesockels 11 die Vorsprünge 21, 22 bereichsweise umgreifen. Durch geeignete konstruktive Maßnahmen kann die kraftschlüssige Wirkverbindung zwischen dem Haltesockel 11 und den Vorsprüngen 21, 22 verbessert sein, beispielsweise in dem an den Vorsprüngen 21, 22 Hügel vorgesehen sind, die in der Klemmnut 15 eintauchen und an diesen anliegen.Consequently, the holding base 11 of the respective connecting body 2 can be pushed into the receiving opening 9 and initially placed there until the base 10 rests on the upper side 5 of the supporting frame 4 and / or the support lugs 24. The two clamping grooves 15 run in the same plane as the projections 21, 22 and the inner contour of the clamping grooves 15 is adapted to the outer contour of the projections 21, 22. As soon as the holding base 11 is inserted into the receiving opening 9, the connecting body 2 can be rotated by approximately 45 °, so that the clamping grooves 15 can be moved in the direction of the respective projection 21, 22. This results in a locking of the holding base 11 on the two projections 21, 22 in the manner of an undercut, since the clamping grooves 15 encompass the projections 21, 22 in regions when the holding base 11 is in the assembled state. The constructive positive connection between the holding base 11 and the protrusions 21, 22 can be improved by suitable constructive measures, for example by providing hills on the protrusions 21, 22, which plunge into the clamping groove 15 and bear against them.

In Figur 3 ist die konstruktive Ausgestaltung des Traggestelles 4 in drei Ansichten abgebildet. Die von der Aufnahmeöffnung 9 gebildeten Felder können mit jeweils einem der Verbindungskörper 2 bestückt sein.In Figure 3 the structural design of the support frame 4 is shown in three views. The fields formed by the receiving opening 9 can each be equipped with one of the connecting bodies 2.

Aus den Figuren 4a und 4b ist ersichtlich, wie der jeweilige Verbindungskörper 2 in die Aufnahmeöffnung 9 einsteckbar und durch Verdrehen mit den Vorsprüngen 21, 22 arretierbar ist, ohne dass die Längskanten 16, 17, die plan ausgestaltet sind, an den Vorsprüngen 21, 22 vorbeigeführt sind, solange bis die Längskanten 18, 19 mit den Klemmnuten 15 in Eingriff mit einem der beiden Vorsprünge 21, 22 gelangen und an diesen arretiert sind.From the Figures 4a and 4b it can be seen how the respective connecting body 2 can be inserted into the receiving opening 9 and locked by twisting with the projections 21, 22, without the longitudinal edges 16, 17, which are of flat design, being guided past the projections 21, 22 until the Longitudinal edges 18, 19 with the clamping grooves 15 come into engagement with one of the two projections 21, 22 and are locked thereon.

Die Größe der jeweiligen Verbindungskörper 2 kann gemäß den Figuren 5a und 5b variieren. Solange der Durchmesser des Verbindungskörpers 2 im Inneren der jeweiligen Aufnahmeöffnung 9 verläuft, kann jede benachbarte Aufnahmeöffnung 9 mit einem Verbindungskörper 9 bestückt sein, so dass alle vorhandenen Aufnahmeöffnungen 9 mit einem zu reinigenden Gegenstand 3 versehen sein können. Sobald der Verbindungskörper 2 einen größeren Durchmesser als die Kantenlänge der Aufnahmeöffnung 9 aufweist, steht der Verbindungskörper 9 über die durch die Stege 7, 8 vorgegebene Begrenzung der Aufnahmeöffnung 9 über, so dass benachbarte Aufnahmeöffnungen 9 abgedeckt sind und folglich zur Aufnahme von weiteren Verbindungskörper 2 nicht genutzt werden können.The size of the respective connecting body 2 can according to the Figures 5a and 5b vary. As long as the diameter of the connecting body 2 extends inside the respective receiving opening 9, each adjacent receiving opening 9 can be equipped with a connecting body 9, so that all existing receiving openings 9 can be provided with an object 3 to be cleaned. As soon as the connecting body 2 has a larger diameter than the edge length of the receiving opening 9, the connecting body 9 projects beyond the boundary of the receiving opening 9 predetermined by the webs 7, 8, so that adjacent receiving openings 9 are covered and consequently not for receiving further connecting bodies 2 can be used.

Das Traggestell 4 ist besonders formstabil, da die Wandstärke der Stege 7, 8 in Bezug auf die Breite B der Stege 7, 8 wesentlich geringer bemessen ist. Zudem verläuft die Breite B in Gravitationsrichtung, so dass Eigengewichtskräfte die Formstabilität des Traggestelles 4 lediglich geringfügig beeinflussen und die Stege 7, 8 diesen Eigengewichtskräften entgegenwirken, da die Breite B der Stege 7, 8 entsprechend ausgebildet ist. Vor allem bei Temperatureinflüssen wirken diese geometrischen Ausbildungen einem Verzug des Traggestelles 4 entgegen.The support frame 4 is particularly dimensionally stable since the wall thickness of the webs 7, 8 is dimensioned to be significantly smaller in relation to the width B of the webs 7, 8. In addition, the width B runs in the direction of gravity, so that self-weight forces only slightly influence the dimensional stability of the support frame 4 and the webs 7, 8 counteract this self-weight force, since the width B of the webs 7, 8 is designed accordingly. These geometrical designs counteract a distortion of the support frame 4, especially when exposed to temperature.

Darüber hinaus kann das Traggestell 4 kostengünstig in einem Kunststoffspritzgussverfahren hergestellt werden und jeder Verbindungskörper 2 kann unabhängig von dessen Größe an einem identisch ausgestalteten Traggestell 4 befestigt werden, wenn nämlich der jeweils verwendete Haltesockel 11 der Verbindungskörper 2 identisch, also unabhängig von der Größe des Verbindungskörpers 2, ausgestaltet ist. Auch wenn die Kantenlänge der Aufnahmeöffnung 9 vergrößert oder verkleinert ist, kann jeder der entsprechend ausgestalteten Haltesockel 11 an dem Traggestell 4 arretiert werden. Es ist lediglich bei der Fertigung des Traggestelles 4 darauf zu achten, dass die Kantenlänge der Aufnahmeöffnung 9 mit der Länge der Vorsprünge 21, 22 in einem identischen Verhältnis steht, derart, dass der Haltesockel 11 in die Aufnahmeöffnung eingesteckt werden kann, dass also die Längskanten 18, 19, die plan ausgestaltet sind, an den Vorsprüngen 21, 22 vorbei dreht werden können und dass die Längskanten 16, 17 mit den Klemmnuten 15 an die Vorsprünge 21, 22 durch Verdrehen bewegt werden können.In addition, the support frame 4 can be produced inexpensively in a plastic injection molding process and each connecting body 2 can be fastened to an identically designed supporting frame 4 regardless of its size, namely if the holding base 11 of the connecting body 2 used in each case is identical, that is to say regardless of the size of the connecting body 2 , is designed. Even if the edge length of the receiving opening 9 is increased or reduced, each of the appropriately designed holding bases 11 can be locked on the support frame 4. It is only necessary to ensure during the manufacture of the support frame 4 that the edge length of the receiving opening 9 is in an identical relationship with the length of the projections 21, 22 such that the holding base 11 can be inserted into the receiving opening, that is to say the longitudinal edges 18, 19, which are flat, can be rotated past the projections 21, 22 and that the longitudinal edges 16, 17 can be moved by twisting with the clamping grooves 15 on the projections 21, 22.

Wenn das Traggestell 4 in einem Kunststoff-Spritzguss-Verfahren hergestellt ist, entsteht ein einstückiges Bauteil, das leicht und handlich einsetzbar bzw. benutzbar ist.If the support frame 4 is produced in a plastic injection molding process, a one-piece component is produced which can be used and used easily and handily.
