Description

Die Erfindung betrifft ein Kühlgerät gemäß dem Oberbegriff des Anspruchs 1. Ein solches Kühlgerät ist z.B. aus der WO 03/062721 A1 bekannt.The invention relates to a cooling device according to the preamble of claim 1. Such a cooling device is for example from the WO 03/062721 A1 known.

Die Erfindung betrifft insbesondere Kühlgeräte, die Verbindungsvorrichtungen besitzen, welche für die Luftzirkulation zur Wanne die Verbindung von verschiedenen Teilen gewähren.The invention particularly relates to refrigerators having connecting devices which provide the connection of different parts for the circulation of air to the tub.

Kühlgeräte bestehen grundsätzlich aus Wärme isolierenden Wänden und - inkludiert in den angeführten Wänden - einer Wanne zur Formung eines Innenrumpfes sowie einer Tür, durch die man aus dem Äußeren in die angeführte Wanne gelangt. Während der Kühlgeräteherstellung werden Wände und Wanne in getrennten Prozessen hergestellt, wobei die Verbindung zwischen diesen durch einen Polyurethan-Gussprozess verwirklicht wird, der auch die Wärmeisolation gewährleistet. Beim Polyurethan-Gussprozess wird eine Form so in die Wanne gelegt, dass ein Entweichen von Polyurethan aus den Löchern auf der Wanne in das Innere der Wanne verhindert und das Wanneninnere geschont wird. Währenddessen wird zwischen das Blech, das die Außenwand formt, und die Wanne, die den Innenrumpf formt, mit Hilfe einer Pistole Polyurethan gespritzt. Das expandierende Polyurethan breitet sich schnell zwischen den Außenwänden und der Wanne aus und füllt den Raum dazwischen. Polyurethan ist ein Material, das während der Expansion dazu neigt, aus allen möglichen Öffnungen zu entweichen. Deshalb wird in die Wanne eine die ganzen Löcher verschließende komplette Form eingesetzt. Aus diesem Grund ist es nicht möglich während der Ausfüllung der Wanne - außer der Wannenform - einen zusätzlichen Vorsprung zu bilden, um Teile daran zu verbinden, weil die Wanne dadurch beschädigt wird. Deshalb werden Elemente, die unter dem Polyurethan zwischen den Außenwänden und der Wanne bleiben, aber deren Verbindung zur Wanne notwendig ist, während dem Polyurethan-Spritzverfahren mit Klebeprodukten wie beispielsweise einem Klebeband an der Außenseite der Wanne befestigt. Während der Expansion des Polyurethans kommt es vor, dass die Klebekraft der an der Wanne befestigten angeführten Klebeprodukte gegenüber der Kraft des Polyurethans nicht ausreichend ist und die Elemente sich verschieben. Da es nicht möglich ist, durch Entfernen der Polyurethanschicht eine Revidierung durchzuführen, kann dies sogar dazu führen, dass das Kühlgerät verschrottet werden muss.Refrigerators basically consist of heat-insulating walls and - included in the listed walls - a trough for forming an inner hull and a door through which one passes from the outside into the cited tub. During the manufacture of the refrigerator, the walls and the tub are produced in separate processes, the connection between which is realized by a polyurethane casting process, which also ensures thermal insulation. In the polyurethane casting process, a mold is placed in the tub so as to prevent polyurethane from escaping from the holes on the tub into the interior of the tub and to protect the inside of the tub. Meanwhile, polyurethane is sprayed between the metal sheet forming the outer wall and the tub forming the inner hull using a pistol. The expanding polyurethane quickly expands between the outer walls and the tub, filling the space in between. Polyurethane is a material that tends to escape from all possible openings during expansion. Therefore, in the tub, a complete mold closing the whole holes is used. For this reason, it is not possible during the filling of the tub - except the pan shape - to form an additional projection to connect parts to it, because the tub is damaged by it. Therefore, elements that remain under the polyurethane between the outer walls and the tub, but whose connection to the tub is necessary, attached during the polyurethane injection process with adhesive products such as an adhesive tape on the outside of the tub. During the expansion of the polyurethane, it happens that the adhesive force of the listed adhesive products attached to the tub is insufficient relative to the force of the polyurethane and the elements shift. Since it is not possible to carry out a revision by removing the polyurethane layer, this can even lead to the fact that the cooling device must be scrapped.

Die Offenlegungsschrift DE 198 40 429 A1 zeigt ein Kältegerät mit einem Normalkühlfach, wobei an einer Innenwand des Normalkühlfaches ein Ausschnitt für eine Beleuchtungseinrichtung gebildet ist.The publication DE 198 40 429 A1 shows a refrigeration device with a normal refrigeration compartment, wherein on an inner wall of the normal refrigeration compartment, a cutout for a lighting device is formed.

Die Patentschrift US 3,177,271 zeigt einen Kühlschrank mit einem Kühlfach, einem Gefrierfach und einem Verdampferfach, wobei die Fächer mittels eines Rohrsystems miteinander verbunden sind.The patent US 3,177,271 shows a refrigerator with a refrigerating compartment, a freezer compartment and an evaporator compartment, wherein the compartments are interconnected by means of a pipe system.

Vom bekannten Stand der Technik ausgehend ist Ziel der Erfindung zu verhindern, dass sich die zwischen der Kühlgerätwanne und den Außenwänden befestigten Elemente nach dem Polyurethan-Spritzverfahren verschieben.Starting from the known state of the art, the object of the invention is to prevent the elements fastened between the refrigerator pan and the outer walls from shifting according to the polyurethane injection method.

Ein anderes Ziel ist, mit einer speziellen Verbindungsmethode und/ oder einem Apparat die verschiedenen Elemente so auf der Wanne zu befestigen, dass diese der Druckkraft des Polyurethans standhalten.Another object is to attach the various elements to the tub with a special connection method and / or apparatus so as to withstand the compressive force of the polyurethane.

Ein anderes Ziel der Erfindung ist, ein weiteres Element auf der Außenfläche der Wanne zu befestigen, ohne dass es die Innenseite beeinträchtigt.Another object of the invention is to attach another element to the outer surface of the tub without affecting the inside.

Um die angegebenen Ziele zu erreichen, wurde ein Kühlgerät gemäß Anspruch 1 verwirklicht. Dieses Kühlgerät besitzt in der Kammer, in deren Inneres die zu kühlenden Produkte gelegt werden, in einem festgelegten Abstand eine einen Zwischenraum bildende und mindestens eine die Oberfläche der Außenfläche der angeführten Kammer schließende Außenwand, ein im angeführten Zwischenraum befindliches und mit einem Ende an der Öffnung auf der Kammer verbundenes Verbindungselement sowie eine Isolationsschicht, die den Raum zwischen der Kammer und der Außenwand füllt und die angeführte Außenfläche der Kammer umhüllt.In order to achieve the stated objectives, a cooling device according to claim 1 has been realized. This refrigerator has in the chamber in which the products to be cooled are placed at a fixed distance a space forming and at least one surface of the outer surface of said chamber closing outer wall, located in said space and with one end to the opening on the chamber connected connecting element and an insulating layer which fills the space between the chamber and the outer wall and encloses the cited outer surface of the chamber.

Erfindungsgemäß verfügt das Kühlgerät über eine Befestigungsverlängerung, die am Ende des angeführten Verbindungselements geformt ist und andererseits Kontakt zur Innenfläche der neben der Öffnung befindlichen Kammer hat. Somit wird das Verbindungselement vor dem Einspritzen der Isolationsschicht an der Kammer befestigt und verändert während des Spritzverfahrens der Isolationsschicht seine Position zum Zwischenraum nicht.According to the invention, the cooling device has a fastening extension, which is formed at the end of the said connecting element and on the other hand has contact with the inner surface of the chamber located next to the opening. Thus, the connector is attached to the chamber prior to injection of the insulating layer and does not change its position to the gap during the injection process of the insulating layer.

Bei einem bevorzugten Aufbau der Erfindung ist das Kühlgerät dadurch gekennzeichnet, dass sich auf der Öffnung mindestens ein ausgeweiteter Abschnitt befindet, damit die angeführte Befestigungsverlängerung durch eine Öffnung gesteckt werden kann. Dadurch kann das Verbindungselement, das an dem Abschnitt, an dem es mit der Öffnung in Kontakt gerät, breiter ist zur Öffnung einen anliegenden Rand bildend vom ausgeweiteten Abschnitt in die Kammer eingezogen werden. Durch seinen Verlauf in den engeren Abschnitt gewährt der breitere Teil somit die Befestigung und berührt die Innenfläche der Kammer.In a preferred construction of the invention, the cooling device is characterized in that there is at least one widened portion on the opening, so that the mentioned fastening extension can be inserted through an opening. Thereby, the connecting element, which at the portion, where it comes into contact with the opening, is wider to the opening an adjacent edge forming the expanded portion are drawn into the chamber. Through its passage into the narrower section, the wider part thus grants the attachment and touches the inner surface of the chamber.

Bei einem bevorzugten Aufbau der Erfindung weist die angeführte Befestigungsverlängerung einen aus dem am gebogenen Ende des Verbindungselements entstehenden Flansch auf. Somit kann die Befestigungsverlängerung seine Position gegen axiale Lasten aus verschiedenen Richtungen schützen.In a preferred construction of the invention, the mentioned fastening extension has a flange formed at the bent end of the connecting element. Thus, the attachment extension can protect its position against axial loads from different directions.

Bei einem bevorzugten Aufbau der Erfindung befindet sich der angeführte erweiterte Abschnitt jedoch am Ende des anderen engeren Teils der Öffnung. Dadurch kann während der Herstellung nach Durchführen des Verbindungselements durch die Öffnung mit nur einer Bewegung eine Montage in Richtung des engeren Abschnitts ausgeführt werden.However, in a preferred construction of the invention, the indicated extended portion is at the end of the other narrower part of the opening. Thereby, during manufacture, after the connecting element has been passed through the opening with only one movement, an assembly can be carried out in the direction of the narrower section.

Bei einer bevorzugten Anwendung der Erfindung befindet sich die Einlageachse der angeführten Öffnung waagrecht zur Bodenfläche. Dies ist die Stabilität betreffend ausreichend, so dass das Verbindungselement mit der Befestigungsverlängerung nur von der unteren und oberen Seite verbunden ist.In a preferred application of the invention, the insertion axis of the mentioned opening is horizontal to the bottom surface. This is sufficient for the stability, so that the connecting member is connected to the fixing extension only from the lower and upper sides.

Bei einem bevorzugten Aufbau der Erfindung ist zur Unterstützung der angeführten Befestigungsverlängerung gegen Spannungen in Richtung Innenseite der Kammer auf dem angeführten Verbindungselement mindestens eine die Außenfläche der Kammer berührende Stützverlängerung vorhanden. Somit bewegt sich das Verbindungselement beim Guss des Isolationsmaterials oder in einer ähnlichen Situation nicht ins Innere der Kammer. Außerdem wird die gegebenenfalls auftretende Momentwirkung der an das Befestigungselement angewendeten Lasten eliminiert.In a preferred construction of the invention, at least one support extension contacting the outer surface of the chamber is provided to support the said attachment extension against tensions towards the inside of the chamber on the said connecting element. Thus, the connecting element does not move into the interior of the chamber during casting of the insulating material or in a similar situation. In addition, the possibly occurring moment effect of the applied to the fastener loads is eliminated.

Bei einem bevorzugten Aufbau der Erfindung befindet sich zwischen der angeführten Befestigungsverlängerung und der Stützverlängerung mindestens eine Aushöhlung, die ein Führungslager bildet. Die angegebene Aushöhlung übernimmt eine Führungsaufgabe und gewährleistet beim Einlegen des Verbindungselements in die Öffnung entsprechend der Kammeroberfläche dessen Führen in die erwünschte Richtung. Gleichzeitig ist es möglich, lediglich eine Aushöhlung zu formen und durch den Teil des Verbindungselements, der sich durch die Aushöhlung ins Kammerinnere hinauf erstreckt, die Befestigungsverlängerung zu bilden.In a preferred construction of the invention, there is at least one cavity between the said attachment extension and the support extension forming a guide bearing. The specified cavity assumes a guiding task and ensures when inserting the connecting element into the opening corresponding to the chamber surface whose guiding in the desired direction. At the same time, it is possible to form only one cavity and to form the attachment extension through the part of the connecting element which extends upwards through the cavity into the interior of the chamber.

Bei einem bevorzugten Aufbau der Erfindung hat der angeführte erweiterte Abschnitt eigentlich die Form eines gleichseitigen Trapezes. Mit solch einer Form wird auf der Öffnung eine sich linear verringernde Breite und durch die sich geradlinig erhöhende Reibung der offen anliegenden Oberflächen der Befestigungsverlängerung eine Erleichterung hinsichtlich der Montage gewährleistet.In a preferred construction of the invention, the cited extended portion is actually in the form of an equilateral trapezoid. With such a shape, a linearly decreasing width is ensured on the opening, and the ease of assembly is ensured by the straight-line increasing friction of the open-fitting surfaces of the fastening extension.

Bei einem bevorzugten Aufbau der Erfindung ist der angeführte erweiterte Abschnitt zur Kammerwand hin geneigt. Auf der Kammer befindet sich mindestens eine zur Ebene der Kammerwand schräge, den angeführten erweiterten Abschnitt tragende Fläche. Somit kann aus dem erweiterten Abschnitt mit einer entsprechend der Kammerebene gerichteten Bewegung die Befestigungsverlängerung eingeschoben werden.In a preferred construction of the invention, the said extended portion is inclined towards the chamber wall. On the chamber is at least one inclined to the chamber wall plane, the said extended section bearing surface. Thus, from the extended portion with a direction of the chamber plane directed movement, the mounting extension can be inserted.

Bei einem bevorzugten Aufbau der Erfindung umschließt die angeführte Flanschform bei der Befestigung des Verbindungselements an die Öffnung die angeführte Öffnungsform, um die Öffnung gänzlich zu schließen. Dadurch wird die Flanschöffnung gänzlich geschlossen und bei Situationen wie dem Polyurethanguss wird das Austreten von Material von selbst verhindert.In a preferred construction of the invention, when attaching the connecting element to the opening, the cited flange shape encloses the mentioned opening shape so as to close the opening completely.

In der in Abbildung 1 dargestellten Anwendung wird die Erfindung an einem Kühlschrank mit zwei Kammern (3, 4) und Accessoires wie Schubfächern und Regalen (in der Abbildung nicht dargestellt) angewendet, wobei die obere Kammer als Kühl- und die untere als Tiefkühlkammer verwendet wird.In the in illustration 1 In the illustrated application, the invention is applied to a refrigerator with two chambers (3, 4) and accessories such as drawers and shelves (not shown in the figure), the upper chamber being used as the cooling chamber and the lower one as the freezing chamber.

Der Außenrumpf (1) ist durch die Biegung einer Metallplatte gebildet, wobei die Öffnungen der Kammern (3, 4) offen bleiben und das dazwischen gespritzte und die Isolationsschicht (2) bildende Polyurethanmaterial die Kammern (3, 4) von der Außenfläche so umschließt, dass ein der Isolationsschicht (2) entsprechender breiter Zwischenraum bleibt. Jedoch wird vor dem Einspritzen der Isolationsschicht (2) zwischen den Außenrumpf (1) und die Kammern (3, 4) in den in diesem Abschnitt befindlichen Zwischenraum (2) ein Verbindungselement (5) eingelegt, das zwischen den Kammern (3, 4) die Luftbeförderung gewährleistet. Das Verbindungselement (5) ist eine hohle rechteckige Kunststoffbrücke, deren zwei Enden in die gleiche Richtung gerichtet und offen sind und deren Inneres einen Kanal (51) bildet. Von zwei in gleicher Richtung gerichteten Öffnungen des Verbindungselements (5) ist eine unten und eine oben befindlich mit den Kammern (3, 4) verbunden. Dadurch wird von der unteren Kammer (4) zur oberen Kammer (5) mit Hilfe eines Ventilators und Luftförderkanälen (in der Abbildung nicht dargestellt) geleitet Kaltluft vom Verbindungselement (5) zur unteren Kammer (3) befördert, um die Zirkulation zu gewährleisten.The outer hull (1) is formed by the bending of a metal plate with the openings of the chambers (3, 4) remaining open and the polyurethane material injected therebetween and forming the insulating layer (2) enclosing the chambers (3, 4) from the outer surface, that a corresponding to the insulating layer (2) wide gap remains. However, before the injection of the insulating layer (2) between the outer hull (1) and the chambers (3, 4) in the intermediate space (2) located in this section, a connecting element (5) is inserted between the chambers (3, 4) ensuring air transport. The connecting element (5) is a hollow rectangular plastic bridge whose two ends are directed and open in the same direction and whose interior forms a channel (51). Of two directed in the same direction openings of the connecting element (5) has a bottom and a top befindlich connected to the chambers (3, 4). Thereby, cold air is conveyed from the lower chamber (4) to the upper chamber (5) by means of a ventilator and air-conveying ducts (not shown in the figure) to the lower chamber (3) from the connecting element (5) to ensure the circulation.

Abbildung 2a zeigt die Öffnung (31), die den Übergang des Verbindungselements (5) zur Kammer (3) gewährleist und durch einen Einschnitt der seitlichen Wand geformt wird. Die Öffnung (31) liegt an der unteren Seite auf der rechten Wand nahe der Öffnung der Kammer (3), der längere Abschnitt ist in waagrechter Lage. Die Öffnung (31) besteht aus einem Rechteck, dessen kürzere Seite gleichzeitig die obere Seite des Trapezes ist und den engen Abschnitt (311) formt, wobei das Trapez den erweiterten Abschnitt (312) formt. Der Ausbreitungswinkel (a), den die auf der Seite des Rechtecks befindliche Trapezform bildet, gewährleistet gegenüber dem engeren Abschnitt (311) eine Erweiterung. Die längere Seite des Trapezes bildet den breiten Rand der Öffnung (31). Die Zwischenraumwand (33) der Öffnung (31) bildet mit der Wanddicke der Kammer (3) eine Lagerfläche für das Verbindungselement (5). Auf der Abbildung hat bei der gezeigten Anwendung die Öffnung (31) eine Greiffläche (32), die von der Wand der Kammer (3) - vom kürzeren Rand der Öffnung (31) - etwas, zum Beispiel 10 mm, breiter als die kürzere Seite der viereckigen Fläche der Öffnung (31) ist, durch die Senkung des Außenrumpfes (1) gebildet wird und an der Zwischenraumwand (33) anliegt. Figure 2a shows the opening (31), which ensures the transition of the connecting element (5) to the chamber (3) and is formed by an incision of the lateral wall. The opening (31) is located on the lower side on the right wall near the opening of the chamber (3), the longer portion is in a horizontal position. The opening (31) consists of a rectangle whose shorter side is at the same time the upper side of the trapezium and forms the narrow portion (311), the trapezoid forming the extended portion (312). The propagation angle (a) formed by the trapezoidal shape on the side of the rectangle provides an enlargement with respect to the narrower portion (311). The longer side of the trapezium forms the wide edge of the opening (31). The intermediate wall (33) of the opening (31) forms with the wall thickness of the chamber (3) has a bearing surface for the connecting element (5). In the figure, in the illustrated application, the opening (31) has a gripping surface (32), that of the wall of the chamber (3) - the shorter edge of the opening (31) - something, for example 10 mm, wider than the shorter side the square surface of the opening (31) is formed by the countersinking of the outer hull (1) and abuts against the gap wall (33).

Wie in Abbildung 2b und Abbildung 3 dargestellt, besitzt das Verbindungselement (5) einen in die Kammer (3) gerichteten viereckigen Befestigungsvorsprung (54), der durch ein Biegen der oberen und unteren Ränder zur Greiffläche (32) hin entsteht. Diese Befestigungsvorsprünge (54) sind entlang der zwei langen, in die Kammer (3) gerichteten, gegenseitigen Ränder geformt, an denen sich die gleichzeitig zum Kanal (51) hin öffnenden Saugöffnungen (52) befinden. Zusammen mit den Befestigungsvorsprüngen (54) ist die Gesamtbreite der Öffnung größer als die Breite des engen Abschnitts (311) - jedoch kleiner als der breiteste Teil des erweiterten Abschnitts (312). Dadurch kann vom Anwender der Befestigungsvorsprung (54), von einem Ende in den Abschnitt, der größer ist als die Gesamtbreite des erweiterten Abschnitts (312), hinein gesteckt und entlang der Laufrichtung des Verbindungselements (A) geschoben werden. Somit werden die Befestigungsvorsprünge (54) von der Kontaktfläche (541) auf die Greiffläche (32) im Inneren der Kammer (3) gestülpt. Um den Steckvorgang zu erleichtern, ist die Kontaktfläche schräg geformt. Der erweiterte Abschnitt (312) befindet sich gegenüber dem engeren Abschnitt (311) näher zur Außenwand. Dadurch kommt es auf der Greiffläche (32) zu keinerlei Belastung, die zu einem Biegen führen könnte.As in Figure 2b and Figure 3 5, the connecting element 5 has a quadrangular fastening projection 54 directed into the chamber 3, which is produced by bending the upper and lower edges towards the gripping surface 32. These fastening projections (54) are formed along the two long, directed into the chamber (3), mutual edges at which the simultaneously opening to the channel (51) suction openings (52) are located. Together with the attachment projections (54), the total width of the opening is larger than the width of the narrow portion (311) - but smaller than the widest part of the extended portion (312). Thereby, the user can insert the attachment projection (54) from one end into the portion larger than the total width of the extended portion (312) and push along the running direction of the connection member (A). Thus, the fastening projections (54) are slipped from the contact surface (541) on the gripping surface (32) inside the chamber (3). To facilitate the insertion process, the contact surface is shaped obliquely. The extended portion (312) is closer to the outer wall than the narrower portion (311). As a result, there is no load on the gripping surface (32) which could lead to bending.

Nachdem der Steckvorgang durchgeführt wurde, wird das Verbindungselement (5) a über den neben dem Befestigungsvorsprung (54) liegenden Befestigungsrand (53) auf die im engeren Abschnitt (311) befindliche Zwischenraumwand (33), gesetzt. Dies gewährleistet, dass das Verbindungselement (5) gegen möglicherweise auftretende Lasten auf der Wandebene der Kammer (3) an der Kammer (3) festgehalten wird.After the mating operation has been carried out, the connecting element (5) a is placed on the intermediate wall (33) located in the narrower section (311) via the fastening edge (53) lying next to the fastening projection (54). This ensures that the connecting element (5) is held against any possible loads on the wall plane of the chamber (3) on the chamber (3).

Bei Lasten, die zur angeführten Ebene senkrecht wirken, verteilen die Befestigungsvorsprünge (54) durch Kontakt auf die Greiffläche (32) die Lasten, die sich von der Kammer (3) zum Außenrumpf ziehen oder aus einem Lastmoment, verbunden mit dem Zentrum an der Kammerzwischenwand, bestehen. Gegen Lasten jedoch, die am Verbindungselement (5) vom Außenrumpf (1) zur Kammer (3) auftreten, ist ein sich neben dem Befestigungsrand (53) befindender rechteckiger Stützvorsprung (55) geformt. Wie in Abbildung 1 gezeigt, verteilt der an der Außenfläche(34) der Kammer liegende Stützvorsprung (55) die angeführten Lasten und verhindert die Bewegung des Verbindungselements (5). Dadurch wird das in alle Richtungen gestützte Verbindungselement (5) von der anderen Öffnung in ähnlicher Form auch an der unteren Kammer (4) befestigt und formt einen geschlossenen Kanal (51) zwischen den Kammern (3, 4). Danach wird in den Zwischenraum zwischen dem Außenrumpf (1) und den Kammern (3, 4) Polyurethan gespritzt. Das Verbindungselement (5) bleibt aufgrund der Stützen konstant gegen die wirkenden Lasten während der Expansion des Polyurethans. Außerdem verbleibt die Greiffläche (32), die in den Kammern (3, 4) entlangläuft und durch eine entsprechende Patrizenform hinten gehalten wird, im hinteren Teil. Eine Beschädigung der Befestigungsvorsprünge (54) wird somit verhindert.For loads that are perpendicular to the indicated plane, the attachment projections (54) distribute, by contact with the gripping surface (32), the loads that extend from the chamber (3) to the outer hull or from a load moment connected to the center at the chamber interface wall , consist. However, against loads occurring on the connecting element (5) from the outer hull (1) to the chamber (3), a rectangular supporting projection (55) located next to the fastening edge (53) is formed. As in illustration 1 shown, the support projection (55) located on the outer surface (34) of the chamber distributes the indicated loads and prevents the movement of the connecting element (5). Thereby, the omnidirectional connection member (5) from the other opening is similarly fixed to the lower chamber (4) and forms a closed channel (51) between the chambers (3, 4). Thereafter, polyurethane is injected into the space between the outer hull (1) and the chambers (3, 4). The connecting element (5) remains constant due to the supports against the loads acting during the expansion of the polyurethane. In addition, the gripping surface (32), which runs in the chambers (3, 4) and is held behind by a corresponding Patrizenform remains in the rear part. Damage to the fastening projections (54) is thus prevented.

Bei anderen Anwendungen der Erfindung kann vorgesehen werden, dass die Öffnung (31) unterschiedlichere Abschnitte des erweiterten Abschnitts (312) darstellt. Beispielsweise können durch Vorsprünge, die sich in eine rechteckige Öffnung erstrecken zwei oder mehr erweiterte Abschnitte (312), oder mit Abschnitten, die zwischen den Vorsprüngen bleiben enge Abschnitte (311) geformt werden. Die angeführten Vorsprünge können in beliebiger Form, wie zum Beispiel dreieckig, kreisförmig usw. sein.In other applications of the invention, it may be provided that the opening (31) represents more different portions of the widened portion (312). For example, protrusions extending into a rectangular opening may form two or more extended portions (312), or with portions remaining between the protrusions, narrow portions (311) may be formed. The cited projections may be in any shape, such as triangular, circular, etc.
