Abstract

An apparatus for fitting a cover to a body structure comprises a main frame; a first body-holding assembly mounted in the main frame, and a second body-holding assembly mounted in the main frame in spaced relationship with the first body-holding assembly. The first body-holding assembly includes an upwardly open, first body-holder means which has at least two mutually opposite and mutually spaced side surfaces and which is intended to receive and to hold one end of the body structure. When fitting a cover to a body structure, the first holder means has draped therearound an inverted back-like cover to be fitted to the body structure. Pressing means are arranged adjacent each of the side surfaces of the first holder means and are arranged for vertical movement in a direction towards the second body-holding assembly while undraping the cover and fitting the same around the defining surfaces of the body structure. The other end of the body structure is held detachably in the second body-holding assembly, which upon movement towards the first body-holding assembly causes the body structure to pushed firmly into the first, upwardly open holder means while entraining and turning part of the inverted cover thereinto.

Description

Vorliegende Erfindung betrifft eine Vorrichtung zum Anbringen von Ueberzügen an Rümpfen, insbesondere bei Autositzrückenlehnen, wie in der Einleitung von Anspruch 1 bezeichnet. Ferner betrifft die Erfindung ein Verfahren zum Ueberziehen eines Rumpfes mittels einer solchen Vorrichtung in Uebereinstimmung mit der Einleitung des ersten Verfahrensanspruches.The present invention relates to a device for applying covers to fuselages, in particular in the case of car seat backrests, as described in the introduction to claim 1. The invention further relates to a method for covering a fuselage by means of such a device in accordance with the introduction of the first method claim.

Das Anbringen von Ueberzügen an insbesondere Autositzrückenlehnen bereitet grosse Probleme, da die Rückenlehnen in zwei Richtungen schalenförmig ausgeführt sind, teils in seitlicher, teils in Höhenrichtung. Die schalenförmige Ausführung in Höhenrichtung ist ausserdem nicht gleichförmig, sondern unregelmässig, um sich der Rückgradform einer sitzenden Person anzupassen. Dies hat ergeben, dass man bisher kein Verfahren erfunden hat, um auf maschinellem Wege derartige Rückenlehnen zu bekleiden. Man hat sich daher bisher gezwungen gesehen, die Ueberzüge von Hand überzustreifen. Abgesehen davon, dass dies ein kostenspieliges Arbeitsverfahren ist, bedeutet es auch Gefahr für Berufsschäden auf Grund unbequemer Arbeitsstellungen, schwerer Hebebewegungen und anderer kraftraubender Arbeitsmomente.The application of covers to car seat backrests, in particular, poses great problems, since the backrests are shell-shaped in two directions, partly in the lateral and partly in the vertical direction. The bowl-shaped design in the height direction is also not uniform, but irregular in order to adapt to the shape of the spine of a seated person. This has shown that no method has yet been invented to mechanically clad such backrests. So far, one has been forced to slip on the coverings by hand. Apart from the fact that this is an expensive working process, it also means a risk of occupational damage due to uncomfortable working positions, heavy lifting movements and other strenuous work moments.

Durch die FR 2 027 533 ist bereits eine weitgehend maschinell arbeitende Vorrichtung zum Ueberziehen von Möbeln vorbekannt. Diese Vorrichtung bedient sich auch einer mit einem links gewendeten Ueberzug zu umgebenden Kassette, durch welche das Möbelstück mit Hilfe von Arbeitszylindern ganz hindurchgepresst wird, wobei der Ueberzug gewendet wird. Um dies überhaupt zu ermöglichen,ist die Kassette geteilt und mit beweglichen Teilen ausgeführt, da ja praktisch fast alle Möbel in irgendeiner Weise profiliert, d.h. unregelmässig ausgeführt sind. Eine straffe Anbringung von eng anliegenden und insbesondere nicht zu stark dehnfähigen Bezügen ist mittels einer solchen Vorrichtung nicht möglich, insbesondere bei stark unregelmässig ausgeführten Möbeln, bei denen sich die Teile z.B. einmal verjüngen, einmal erweitern, einmal konvex und einmal konkav sind. Dabei lenken nämlich die Kassettenteile durch zuerst überzogene vorstehende Teile aus, ohne sich einer nachfolgenden Verjüngung oder dgl. konturfolgend anpassen zu können. Auch ist die gemeinsame Anlenkung der Kassettenteile an einer oder zwei gemeinsamen Schwenkachsen aus diesen Gründen nachteilig, zumal die Kassettenteile noch gerade ausgeführt sind. Ferner kann es nachteilig sein, die Möbelteile in verschiedenen Höhenlagen einsetzen und nach dem Ueberziehen herausnehmen zu müssen. Dies dient auch nicht dem Anschluss eines z.B. automatischen Zubringens/Abtransportes. Ferner dürften die bezogenen Möbel gemäss gewissen Ausführungen nach dieser Schrift aus einer tiefen Lage zunächst senkrecht angehoben werden müssen, um aus der Kassette entfernt werden zu können, was zeitraubend und anstrengend ist. Auch die Anbringung von Zusatzausrüstung, d.h. über einen Ueberzug hinausgehende Teile, dürfte schwierig oder sogar unmöglich sein. Eine Umstellung auf andere Möbel ist zweifelsohne kostenspielig und zeitraubend, wenn in gewissen Fällen überhaupt mögliche und dürfte in den meisten Fällen einen Austausch der gesamten Kassette bedingen.FR 2 027 533 already discloses a largely mechanical device for covering furniture. This device also uses one a cover turned to the left to surround the cassette, through which the piece of furniture is pressed completely with the aid of working cylinders, the cover being turned. In order to make this possible at all, the cassette is divided and designed with moving parts, since practically all furniture is profiled in some way, that is to say irregularly. A tight fitting of tight-fitting and in particular not too extensible covers is not possible with such a device, particularly in the case of furniture with a very irregular design, in which the parts taper once, expand once, are convex and are concave. This is because the cassette parts are deflected by protruding parts that are first coated, without being able to adapt to a subsequent taper or the like. The joint articulation of the cassette parts on one or two common pivot axes is disadvantageous for these reasons, especially since the cassette parts are still straight. Furthermore, it can be disadvantageous to use the furniture parts at different heights and to have to remove them after covering them. This also does not serve to connect, for example, automatic feeding / removal. Furthermore, according to certain explanations according to this document, the upholstered furniture may first have to be lifted vertically from a deep position in order to be able to be removed from the cassette, which is time-consuming and exhausting. Attaching additional equipment, ie parts that go beyond a covering, may also be difficult or even impossible. Switching to other furniture is undoubtedly costly and time-consuming, if at all possible in certain cases, and in most cases may require the entire cassette to be replaced.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung einer Vorrichtung, welche die Notwendigkeit eines manuellen Ueberziehens ausschaltet und ein möglichst vollmaschinelles Ueberziehen gestattet, einfach und schnell in der Funktion ist, geringe Herstellungskosten verursacht, grosse Betriebssicherheit aufweist und leicht, schnell, einfach und kostensparend auf verschiedene Rümpfe umzustellen ist. Aufgabe der Erfindung ist auch die Schaffung eines Verfahrens zum Ueberziehen eines Rumpfes mittels einer solchen Vorrichtung.The object of the present invention is therefore to provide a device which avoids the need manual overturning and fully automatic overturning is permitted, is simple and quick to operate, has low manufacturing costs, is extremely reliable and can be easily, quickly, easily and economically converted to different hulls.

Between the yoke 30 and the crossbeam 22, two lateral guide rods 32 are fastened, along which the holding device 14 and the pressure bracket 16, 18 travel. The holding device 14 consists of two guide shoes 34 and a frame 36 connecting the latter, on which displaceable sliding shoes 38 are arranged. The latter are preferably provided with retaining bolts (not shown) and have fastenings for exchangeable and length-adjustable holders 40. The latter have fastening members for a backrest to be covered, for example as recesses 42. The holding device 14 can be moved in the longitudinal direction of the guide rods with the aid of a working cylinder 44, which is attached to the yoke of the frame. The holding device is fastened to the piston rod 46 of the working cylinder with the aid of a fastening device 48. This is preferably designed such that it allows a variable fixing in the longitudinal direction of the piston rod in order to adapt the position of the holding device to backrests of different lengths.

Die Anpressbügel 16, 18 sind an Befestigungsorganen 50 verankert, die ihrerseits an einem Wagen 52 befestigt sind. Der Wagen besteht aus zwei Führungsschuhen 54, einem Doppelrahmen 56 und einer freiliegenden Vierkantstange 58, die sich zwischen den Führungsschuhen erstreckt. An der Stange 58 sind die Befestigungsorgane 50 mit Hilfe einer Vierkanthülse 60 festgesetzt, die mit einem Verriegelungsbolzen 62 versehen ist. Aus der Vierkanthülse ragt eine Vierkantstange 64 hervor, die den vierkantigen Rumpf 66 der Befestigungsorgane trägt. Der Rumpf ist auf der Stange 64 verschiebbar und wird mit Hilfe von Befestigungsbolzen 68 in seiner Lage verriegelt. An den Rümpfen sind Befestigungsorgane 70 zur Anlenkung der Bügel 16, 18 und Befestigungsorgane 72 aus Flacheisen für Anpresszylinder 74, 76 der Bügel 16, 18 befestigt. Dabei sind die Anpresszylinder 74 an dem vorderen Bügel 16 und die Anpresszylinder 76 an dem hinteren Bügel 18 festgesetzt. Der vordere Bügel 16 besteht aus dem eigentlichen Bügel 16, welcher in rohrförmige Schenkel 78 eingeschoben ist. Auf gleiche Weise ist der hintere Bügel 18 in rohrförmige Schenkel 80 eingeschoben. Auf diese Weise ist es möglich, die Montagevorrichtung auf verschieden breite Rückenlehnen umzustellen, indem die Anpressbügel 16, 18 ausgetauscht und die Befestigungsorgane seitlich in die richtige Lage versetzt werden.The pressure clamps 16, 18 are anchored to fastening members 50, which in turn are fastened to a carriage 52. The carriage consists of two guide shoes 54, a double frame 56 and an exposed square bar 58 which extends between the guide shoes. The fastening members 50 are fixed to the rod 58 with the aid of a square sleeve 60 which is provided with a locking bolt 62. A square rod 64 protrudes from the square sleeve and carries the square body 66 of the fastening elements. The fuselage is displaceable on the rod 64 and is locked in position by means of fastening bolts 68. Fastening members 70 for articulating the brackets 16, 18 and fastening members 72 made of flat iron for pressure cylinders 74, 76 of the brackets 16, 18 are fastened to the fuselages. The pressure cylinders 74 are on the front bracket 16 and the pressure cylinders 76 fixed to the rear bracket 18. The front bracket 16 consists of the actual bracket 16, which is inserted into tubular leg 78. In the same way, the rear bracket 18 is inserted into tubular leg 80. In this way it is possible to convert the mounting device to backrests of different widths by exchanging the pressure brackets 16, 18 and moving the fastening elements laterally into the correct position.

Die Befestigungsorgane mit den Anpressbügeln und dem Wagen 52 sind fahrbar mit Hilfe eines doppelwirkenden Arbeitszylinders 82, der an dem Joch 30 befestigt ist. Die Kolbenstange 84 des Arbeitszylinders ist an dem Wagen 52 mit Hilfe einer Befestigungsvorrichtung 86 befestigt, so dass die Wagenlage in Längsrichtung der Kolbenstange einstellbar ist.The fastening elements with the pressure brackets and the carriage 52 can be moved by means of a double-acting working cylinder 82 which is fastened to the yoke 30. The piston rod 84 of the working cylinder is fastened to the carriage 52 with the aid of a fastening device 86, so that the carriage position can be adjusted in the longitudinal direction of the piston rod.

Die erfindungsgemässe Vorrichtung wird auf folgende Weise angewendet. Ein mit der Innenseite nach aussen gewendeter, einseitig offener Ueberzug wird über die Kassette 12 und die Anpressbügel 16, 18 gestreift. Eine Rückenlehne wird darauf mit ihrem einen Ende auf die Kassette gesetzt und mit dem anderen Ende an den Haltern 40 befestigt. Die Halter können dabei derart ausgeführt sein, dass sie mit an der Rückenlehne befindlichen Montageelementen zusammenwirken. Die Halter sind vorzugsweise mit Schnellbefestigungsvorrichtungen für die Rückenlehne versehen, so dass diese in Längsrichtung verschoben werden kann, ohne sich von den Haltern zu lösen. Derartige Schnellbefestigungsorgane können verschiedene federbelastete Verriegelungsorgane oder ganz einfach eine Erweiterung im Inneren der Aussparungen 42 sein. Auf diese Weise wird ein zeitraubendes Festschrauben der Rückenlehne vermieden.The device according to the invention is used in the following way. A coating which is turned inside out and is open on one side is slipped over the cassette 12 and the pressure bracket 16, 18. A backrest is then placed at one end on the cassette and attached to the holders 40 at the other end. The holders can be designed such that they interact with mounting elements located on the backrest. The holders are preferably provided with quick fastening devices for the backrest, so that the backrest can be displaced in the longitudinal direction without detaching from the holders. Such quick fastening members can be various spring-loaded locking members or can simply be an extension inside the recesses 42. In this way, time-consuming screwing of the backrest is avoided.

Jetzt wird der doppelwirkende Arbeitszylinder 44 betätigt, welcher die Kolbenstange 46 hinauspresst, wobei die Haltevorrichtung 14 und die Rückenlehne mitgeführt werden, so dass das eine Rückenlehnenende in die Kassette 12 eingepresst wird, bis es den Boden der Kassette erreicht hat. Die Rückenlehne zieht dabei den Ueberzug mit sich in die Kassette, wobei dieser richtig gewendet und über den in der Kassette befindlichen Rückenlehnenteil gestreift wird. Darauf wird der zweite doppelwirkende Arbeitszylinder 82 betätigt, welcher die Kolbenstange 84 einzieht, wobei der Wagen 52, die Befestigungsorgane 50 und die Bügel 16, 18 in Richtung auf das andere Rückenlehnenende bewegt werden. Die Anpresszylinder 74 ziehen dabei den vorderen Anpressbügel gegen die Vorderseite der Rückenlehne, während die Anpresszylinder 76 den hinteren Anpressbügel 18 gegen die Rückseite der Rückenlehne pressen. Die Bügel 16, 18 befinden sich dabei in der Wendefalte des teilweise gewendeten Ueberzuges und bewirken ein fortlaufendes Wenden während ihrer Bewegung auf das andere Rückenlehnenende zu. Am Ende der Kolbenbewegung ist der Ueberzug völlig gewendet und umgibt die Rückenlehne in richtig gewendeter Lage.Now the double-acting working cylinder 44 is actuated, which presses out the piston rod 46, the holding device 14 and the backrest being carried along, so that the one backrest end is pressed into the cassette 12 until it has reached the bottom of the cassette. The backrest pulls the cover with it into the cassette, turning it correctly and sliding it over the backrest part located in the cassette. Then the second double-acting working cylinder 82 is actuated, which retracts the piston rod 84, the carriage 52, the fastening elements 50 and the brackets 16, 18 being moved in the direction of the other backrest end. The pressure cylinders 74 pull the front pressure bracket against the front of the backrest, while the pressure cylinders 76 press the rear pressure bracket 18 against the back of the backrest. The brackets 16, 18 are in the turning fold of the partially turned cover and cause a continuous turning during their movement towards the other end of the backrest. At the end of the piston movement, the cover is completely turned and surrounds the backrest in the correct turned position.

Nach dem Ueberziehen der Rückenlehne wird der Arbeitszylinder 82 gegenläufig aktiviert und zieht dabei die Anpressbügel 16, 18 in ihre Ausgangslage nahe der Kassette 12 zurück. Darauf wird der Arbeitszylinder 44 in entgegengesetzter Richtung betätigt und zieht die Rückenlehne aus der Kassette 12, worauf die Rückenlehne von den Haltern 40 gelöst und ein neuer Arbeitszyklus beginnen kann.After the backrest has been pulled over, the working cylinder 82 is activated in the opposite direction and thereby pulls the pressure brackets 16, 18 back into their starting position near the cassette 12. Then the working cylinder 44 is actuated in the opposite direction and pulls the backrest out of the cassette 12, whereupon the backrest can be released from the holders 40 and a new working cycle can begin.

Es ist besonders wichtig, dass der Anpressbügel 16 mit grosser und beibehaltener Kraft gegen die Rückenlehne gepresst wird, da diese Seite sich von Bügel weg krümmt. Daher sind pneumatisch betätigte Anpresszylinder besonders geeignet, da solche einen konstanten Anpressdruck unabhängig von der Bügellage ausüben können. Die Anforderungen an den hinteren Anpressbügel 18 bezüglich Anpresskraft sind geringer, da die Rückenlehne zum Bügel hin gekrümmt ist. Daher lässt sich hier ein Anpresszylinder mit geringerem Arbeitsdruck und/oder Zylinderdurchmesser oder ein einfacheres Anpressmittel verwenden, z.B. ein Feder.It is particularly important that the pressure bracket 16 is pressed against the backrest with great and retained force, since this side curves away from the bracket. Pneumatically actuated pressure cylinders are therefore particularly suitable, as they have a constant pressure can exercise regardless of the temple position. The requirements for the rear pressure bracket 18 with regard to the pressing force are lower since the backrest is curved toward the bracket. Therefore, a pressure cylinder with a lower working pressure and / or cylinder diameter or a simpler pressure medium, such as a spring, can be used here.

Die erfindungsgemässe Montagevorrichtung lässt sich für verschieden grosse Rückenlehnen verwenden. Beim Uebergang zu einer anderen Grösse tauscht man die Kassette 12 und die Anpressbügel 16, 18 gegen solche einer passenden Grösse aus und bewegt die Vierkanthülsen 60 in die richtige Seitenlage. Ferner werden die Gleitschuhe 38 mit den Haltern 40 entsprechend der neuen Rückenlehnenbreite seitlich verschoben. Eventuell werden die Halter 40 gegen andere ausgetauscht, die der neuen Rückenlehne passen. Ferner wird die Haltevorrichtung 14 in Höhenrichtung eingestellt mit Hilfe der Befestigungsvorrichtung 48 entsprechend der Länge der neuen Rückenlehne. Die Bügel 16, 18 können eventuell auch in Höhenrichtung mit Hilfe der Befestigungsvorrichtung 86 bei Bedarf eingestellt werden.The mounting device according to the invention can be used for backrests of different sizes. When changing to another size, the cassette 12 and the pressure clamps 16, 18 are exchanged for those of a suitable size and the square sleeves 60 are moved into the correct lateral position. Furthermore, the sliding shoes 38 are moved laterally with the holders 40 in accordance with the new backrest width. The brackets 40 may be replaced with others that fit the new backrest. Furthermore, the holding device 14 is adjusted in the height direction with the aid of the fastening device 48 in accordance with the length of the new backrest. The brackets 16, 18 can possibly also be adjusted in the vertical direction using the fastening device 86 if required.

Die gezeigte und beschriebene Montagevorrichtung arbeitet mit Hilfe einer Anzahl Arbeitszylinder, die vorzugsweise pneumatisch betrieben werden. Die Arbeitszylinder sind vorzugsweise sequenzgesteuert von einer Steuerzentrale,/so dass nach dem Richten und Anbringen von Ueberzug und Rückenlehne alle Arbeitsmomente durch Aktivieren einer einzigen Startreglage in einer Folge ausgeführt werden können.The assembly device shown and described works with the aid of a number of working cylinders, which are preferably operated pneumatically. The working cylinders are preferably sequence-controlled by a control center, / so that after the covering and backrest have been straightened and attached, all working moments can be carried out in a sequence by activating a single starting control.

Die Vorrichtung lässt sich auch mit Hilfe von hydraulischen Zylindern und anderen Antriebsvorrichtungen betreiben, z.B. elektrischen Motoren. Auch ein manueller Betrieb mittels Hebeln und/oder Pedalen ist denkbar. Es ist auch möglich, irgendwelche verschiedenen Kraftquellen für die erfindungsgemässe Montagevorrichtung zu kombinieren. Beispielsweise lässt sich die Bewegung der Bügel 16, 18 und der Haltevorrichtung 14 mit Hilfe von pneumatischen Zylindern 44, 82 ausführen, während die Bügel 16, 18 gegen die Seiten der Rückenlehne mit anderen Mitteln gepresst werden, beispielsweise Federkraft oder geeigneten Gegengewichten.The device can also be operated with the aid of hydraulic cylinders and other drive devices, for example electric motors. Manual operation using levers and / or pedals is also conceivable. It it is also possible to combine any different power sources for the mounting device according to the invention. For example, the movement of the brackets 16, 18 and the holding device 14 can be carried out with the aid of pneumatic cylinders 44, 82, while the brackets 16, 18 are pressed against the sides of the backrest by other means, for example spring force or suitable counterweights.

Die Bügelform muss nicht unbedingt die gezeigte einfache Form sein. Die Bügel können beispielsweise gebogen sein, so dass sie der Rückenlehnenkontur folgen. Die Bügel können auch eine Platte besitzen, die der Rückenlehnenkontur folgt. Die Bügelschenkel müssen auch nicht unbedingt an den Rückenlehnenseiten angeordnet sein, sondern können auch der Rückenlehnenvorder- und Rückenseite folgen, wobei ein Teil der Bügel seitlich ausserhalb der Schenkel abragt. Dies ist jedoch oft mit Schwierigkeiten verbunden, da die Bügel der Rückenlehnenkontur durchweg folgen sollen können und am Ende angeordnete Schenkel sind daher vorzuziehen.The bow shape does not necessarily have to be the simple shape shown. The brackets can be curved, for example, so that they follow the contour of the backrest. The brackets can also have a plate that follows the contour of the backrest. The stirrup legs do not necessarily have to be arranged on the backrest sides, but can also follow the backrest front and back side, with a part of the stirrup protruding laterally outside the leg. However, this is often associated with difficulties, since the brackets should be able to follow the contour of the backrest throughout and legs arranged at the end are therefore preferable.

Fig. 1 zeigt eine stehende Montagevorrichtung mit der Kassette am unteren Ende. Es ist natürlich auch möglich, die Montagevorrichtung liegend auszuführen. Sie kann dabei vorzugsweise mit einer Stütze für die Rückenlehne versehen sein, die selbsttätig entfernt wird, nachdem die Rückenlehne in die Kassette eingeschoben wurde. Ferner lässt sich die Vorrichtung stehend ausführen mit im oberen Bereich oder auf andere Weise angeordneter Kassette.Fig. 1 shows a standing mounting device with the cassette at the lower end. It is of course also possible to carry out the mounting device horizontally. It can preferably be provided with a support for the backrest, which is automatically removed after the backrest has been inserted into the cassette. Furthermore, the device can be carried upright with a cassette arranged in the upper region or in another way.

Die Anpresszylinder und insbesondere die Zylinder 74 sind vorzugsweise doppelwirkend. Dadurch ist es möglich, nach dem Anbringen eines Ueberzuges auf der Rückenlehne den Bügel 16 von letzterer wegzuziehen, so dass er nicht an dieser während seiner Rückbewegung in die Ausgangslage anliegt.The pressure cylinders and in particular the cylinders 74 are preferably double-acting. This makes it possible after pulling a cover on the backrest to pull the bracket 16 away from the latter, so that it is not on it during its return movement into the off position current situation is present.

Die Montagevorrichtung besitzt vorzugsweise Stoppvorrichtungen für die Fahrbewegungen der Haltevorrichtung bzw. der Anpressbügel. Diese können vorzugsweise im Anschluss an die Führungsstangen angeordnet sein. Ferner sind mit Vorteil Endlagenschalter bei den gewünschten Endlagen der verschiedenen Bewegungen angeordnet. Derartige Endlagenschalter können einen Impuls auslösen, um eine Fahrbewegung zu stoppen und/oder eine neue zu starten. Derartige Endlagenschalter können vorteilhaft zu einem Sequenzsteuersystem für zwei oder mehrere Arbeitsmomente gehören. Mit Hilfe von Endlagenschaltern und anderen Organen für die Sequenzsteuerung kann es möglich sein, die Ueberzuganbringung in einem einzigen Arbeitsvorgang ohne Mitwirken des Bedienungspersonals auszuführen.The mounting device preferably has stop devices for the travel movements of the holding device or the pressure bracket. These can preferably be arranged after the guide rods. Furthermore, limit switches are advantageously arranged at the desired end positions of the various movements. Such limit switches can trigger a pulse to stop a travel movement and / or to start a new one. Such limit switches can advantageously belong to a sequence control system for two or more working moments. With the help of limit switches and other organs for the sequence control, it may be possible to apply the cover in a single operation without the involvement of the operating personnel.

Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel begrenzt, sondern lässt sich im Rahmen folgender Patentansprüche abändern, ohne vom Erfindungsgedanken abzuweichen.The invention is not limited to the exemplary embodiment described, but can be modified within the scope of the following claims without departing from the inventive concept.

So zeigt Fig. 3 eine bevorzugte Ausführungsform von Haltern 40 mit nach unten gerichteten Klauen 101, 102, welche auf ihren einander zugewendeten Seiten mit Absätzen 103 und Schrägen 104 ausgeführt sind, um z.B. querlaufende Stangen einer Rückenlehne sicher zu halten. Dabei ist wenigstens eine der Klauen von einer Feder und/ oder einem druckmittelbetätigten Arbeitszylinder (nicht gezeigt) auf an sich bekannte Weise beaufschlagt, welche den Rumpf während der Arbeitsvorgänge sicher halten und am Ende freigeben, wobei wenigstens eine der Klauen vorzugsweise ausgelenkt oder weggeschwenkt wird.3 shows a preferred embodiment of holders 40 with downward-pointing claws 101, 102, which are provided on their mutually facing sides with shoulders 103 and bevels 104, e.g. to hold transverse bars of a backrest securely. At least one of the claws is acted upon by a spring and / or a pressure-actuated working cylinder (not shown) in a manner known per se, which holds the fuselage securely during the work processes and releases it at the end, at least one of the claws preferably being deflected or pivoted away.

Fig. 4 und 5 zeigen eine bevorzugte Kassetten- und Bügelform, wobei man erkennt, dass die Kassette nur Vorder-und Rückseite 15, 15', aber keine Schmalseiten aufweist.4 and 5 show a preferred cassette and bracket shape, it being recognized that the cassette has only the front and back 15, 15 ', but no narrow sides.

Die beiden Seiten sind über einen Boden miteinander verbunden, der eventuell nur in Form von zwei Distanzstücken 105 vorhanden sein kann, worauf sich vorteilhaft z.B. Führungshülsen 106 für Kopf- und Nackenstützen in Lokalisierungsanweisungen 107 anordnen lassen. Beim Anbringen eines für diese Hülsen mit Öffnungen versehenen Ueberzuges werden die Hülsen durch die Öffnungen geführt und dann bei der Abwärtsbewegung des Rumpfes selbsttätig in diesen eingepresst. Zwecks leichter Zugänglichkeit der Lokalisierungsanweisungen können die oberen Kassettenecken auch wie in Fig. 5 gezeigt ausgeschnitten sein.The two sides are connected to one another via a base, which may possibly only be in the form of two spacers 105, which is advantageous, e.g. Arrange guide sleeves 106 for headrests and neckrests in localization instructions 107. When attaching a covering provided with openings for these sleeves, the sleeves are guided through the openings and then automatically pressed into the fuselage as the fuselage moves downward. The upper cassette corners may also be cut out as shown in FIG. 5 for ease of access to the location instructions.

Die Kassettenseiten sind oben mittig mit einer z.B. V-förmigen Aussparung 108 versehen, die auf der Kassetteninnenseite von einem Anschlag 109 hinterlegt ist. Entsprechend ist jeder Bügelsteg mittig mit einer in die Aüssparung passenden Abbiegung 110 versehen. So lassen sich beide Bügel in ihrer Ausgangslage von nicht gezeigten Federmitteln gegen den zugehörigen Anschlag 109 pressen, wobei der Bügelsteg innerhalb der betreffenden Kassettenseitenebene liegt. Da die Bügel aus Rundeisen bestehen, gleitet der Ueberzug auf diese Weise geschmeidig an ihnen vorbei, während er mit den Kassettenseiten praktisch überhaupt nicht in Berührung kommt. Eine perfekte Ausgangslage und Friktionsarmut werden somit gewährleistet.The sides of the cassette are centered with e.g. V-shaped recess 108 is provided, which is deposited on the inside of the cassette by a stop 109. Accordingly, each stirrup bar is provided in the middle with a bend 110 that fits into the recess. In this way, both stirrups in their starting position can be pressed by spring means (not shown) against the associated stop 109, the stirrup web lying within the relevant cassette side plane. Since the brackets are made of round iron, the cover glides smoothly past them while practically not touching the sides of the cassette. A perfect starting point and low friction are guaranteed.

Fig. 4 deutet an, wie vorteilhaft sich die Bügel in Spezialausführung an verschiedene Rumpfformen anpassen lassen. Durch entsprechende Krümmungen etc. folgen die Bügel jeder beliebigen Rumpfform unter engem Anliegen und damit friktions- und spannungsarm, wodurch wiederum besonders eng anliegende Ueberzüge angewendet werden können, wie dies z.B. bei Autositzrückenlehnen erwünscht ist. Vorteilhaft lassen sich die Bügelstege und -schenkelansätze als austauschbare Teile ausführen, wobei die Schenkelansätze einfach in die vorzugsweise geraden,schwenkbar angelenkten Bügelschenkelteile einschiebbar oder auf diese aufschiebbar vorgesehen sind.Fig. 4 indicates how advantageous the special temples can be adapted to different hull shapes. By means of appropriate curvatures, etc., the stirrups follow any shape of trunk with a tight fit and are therefore low in friction and tension, which in turn allows particularly close-fitting covers to be used, as is desired, for example, in car seat backrests. Advantageously, the strap webs and leg attachments can be designed as interchangeable parts, the leg attachments simply being insertable into, or onto, the preferably straight, pivotably hinged strap leg portions are slidably provided.

Auch erlaubt die Erfindung eine vorteilhafte, einfache und schnelle Anbringung von weiterer Zusatzausrüstung bei einer stets bequemen und richtigen Arbeitsstellung für das Personal, welches sich nie bücken braucht oder schwere Arbeitsbewegungen auszuführen hat. So lässt sich beispielsweise die Aufwärtsbewegung der Bügel in einer beliebigen Höhenlage stoppen, so dass man die eine Ueberzugsseite mit der anderen verbinden kann, was z.B. dadurch geschieht, dass man eingenähte Querstäbe auf der einen Innenseite des Ueberzuges mit solchen auf der anderen Ueberzugsinnenseite durch Haken oder dgl. verbindet.The invention also allows an advantageous, simple and quick attachment of additional equipment in a comfortable and correct working position for the staff who never have to bend down or have to carry out heavy work movements. For example, the upward movement of the brackets can be stopped at any height, so that one side of the cover can be connected to the other, which e.g. this is done by connecting sewn-in cross bars on one inside of the cover with those on the other inside of the cover by hooks or the like.

Besonders hervorzuheben ist noch der Vorteil der flachen, feststehenden Kassette in richtiger Höhenlage. Die Kassette dient somit als Anschlag und Halterung für einen Rumpf, während die Bügel praktisch allein für das Ueberziehen Sorge tragen. Dabei ist zu bemerken, dass sich der Ueberzug auch in einen Bügel hineinerstrecken kann, z.B. wie er in Fig. 4 gezeigt ist. Eine Anbringung von engsten Ueberzügen auf den schwierigsten Rümpfen bei minimaler Friktion ist somit möglich.Of particular note is the advantage of the flat, fixed cassette at the correct height. The cassette thus serves as a stop and holder for a fuselage, while the brackets practically take care of the covering. It should be noted that the cover can also extend into a bracket, e.g. as shown in Fig. 4. It is therefore possible to apply the tightest covers on the most difficult hulls with minimal friction.

Es ist natürlich nicht notwendig, dass die Rümpfe bis auf den Kassettenboden eingeschoben werden. Ein geringfügiges begrenztes Einschieben in die Kassette kann voll ausreichen. Insbesondere in einem solchen Fall braucht der Zylinder 44 nach beendetem Ueberziehen das fertige Teil nicht aus der Kassette herauszuheben. Stattdessen kann es vorteilhaft sein, wenn die Halter 40, 42 das fertige Teil freigeben, z.B. durch Wegschwenken eines pneumatisch betätigten Halterteils, worauf der Zylinder 44 die Vorrichtung 14 in ihre Ausgangslage zurückfährt und das fertig bezogene Teil einfach aus der Kassette entnommen werden kann. Auch können beide Bügel 16, 18 pneumatisch betätigbar und z.B. über Reduzierventile einstellbar sein. Auf diese Weise spielt es keine grosse Rolle mehr, wie die beiden Hauptseiten eines zu überziehenden Gegenstandes ausgeführt sind, d.h. man kann die Seiten nach Belieben wenden oder wählen. Schliesslich lässt sich die erfindungsgemässe Vorrichtung auch auf an sich bekannte Weise neigbar anordnen.It is of course not necessary that the hulls are pushed down to the bottom of the cassette. A slight limited insertion into the cassette can be sufficient. In such a case in particular, the cylinder 44 does not need to lift the finished part out of the cassette after the covering has been completed. Instead, it can be advantageous if the holders 40, 42 release the finished part, for example by pivoting away a pneumatically operated holder part, whereupon the cylinder 44 moves the device 14 back into its starting position and the finished part can simply be removed from the cassette. Also, both brackets 16, 18 can be actuated pneumatically and, for example, via reducing valves be adjustable. In this way, it no longer matters how the two main sides of an object to be covered are designed, ie you can turn or choose the sides as you wish. Finally, the device according to the invention can also be arranged tiltably in a manner known per se.
