Description

Die vorliegende Erfindung betrifft eine Abstützeinrichtung gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a support device according to the preamble of claim 1.

Aus der US 6,431,522 B1 ist eine gattungsgemäße Abstützeinrichtung bekannt. Der Rahmen dieser bekannten Abstützeinrichtung umfasst Mittel zur Fixierung derselben an einem Objekt, z. B. an dem Schweller eines Fahrzeugs, in Form einer unteren sowie einer oberen Abstützplatte, zwischen denen ein Teil des Objekts, z. B. der Schweller des Fahrzeugs mittels eines Hydraulikstempels nach Art eines Schraubstocks eingespannt wird. Diese Abstützeinrichtung ist zwar variabel einsetzbar, aber durch den notwendigen Einsatz eines Hydraulikstempels vorrichtungstechnisch sehr aufwendig.From the US 6,431,522 B1 is a generic support known. The scope of this known support means comprises means for fixing the same to an object, for. B. on the sills of a vehicle, in the form of a lower and an upper support plate, between which a part of the object, for. B. the sill of the vehicle is clamped by means of a hydraulic ram in the manner of a vise. Although this support device is variably applicable, but by the necessary use of a hydraulic temple device technology very expensive.

Aus der DE 198 13 404 A1 ist ein Stützwinkel zur Abstützung und Verkürzung der Abstützlänge eines Spreizgeräts bekannt. Dieser Stützwinkel ist dazu vorgesehen, in den Bereich des Übergangs zwischen Türholm und Schweller eines Fahrzeugs eingesetzt zu werden. Er hat damit den Nachteil, dass er nur an dieser vorbestimmten Stelle des Fahrzeugs einzusetzen ist. Ist diese Stelle unfallbedingt stark verformt, kann der Abstützwinkel nicht mehr eingesetzt werden.From the DE 198 13 404 A1 is a support bracket for supporting and shortening the support length of a spreading known. This support bracket is intended to be used in the region of the transition between the door spar and sill of a vehicle. He has the disadvantage that he is only to use at this predetermined location of the vehicle. If this point is heavily deformed due to an accident, the support bracket can no longer be used.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine neuartige Abstützeinrichtung zur Verfügung zu stellen, die einen einfachen vorrichtungstechnischen Aufbau besitzt, gleichzeitig aber variabel einsetzbar ist.The object of the present invention is to provide a novel support means available, which has a simple device construction, but at the same time is used variably.

Die vorliegende Aufgabe wird bei der gattungsgemäßen Abstützeinrichtung dadurch gelöst, dass

  1. a) die eine Abstützkralle (3) einen nach außen gekrümmten, in Längsrichtung der Abstützkralle (3) geraden Anlagebereich (7) für ein Endstück des Spreizzylinders (17) aufweist und
  2. b) die Abstützkrallen (3, 4) so ausgebildet sind, dass sie auch in schräger Anlage an den Türausschnitt wirksam sind und sich bei Belastung der Abstützeinrichtung (1) durch den Spreizzylinder (17) allein durch Verkanten der beiden Abstützkrallen (3, 4) gegenüber dem zwischen ihnen befindlichen Türausschnitt ein Selbsthalteeffekt einstellt und
  3. c) die Abstützkrallen(3, 4) jeweils zwei schmale, langgezogene und kantenförmige Anlageflächen (5) aufweisen.
The present object is achieved in the generic support device characterized in that
  1. a) a Abstützkralle (3) has an outwardly curved, in the longitudinal direction of the Abstützkralle (3) straight contact area (7) for an end of the expansion cylinder (17) and
  2. b) the Abstützkrallen (3, 4) are designed so that they are effective even in oblique contact with the door cutout and under load of the support means (1) by the Spreizzylinder (17) alone by tilting the two Abstützkrallen (3, 4) opposite to the door opening between them sets a self-holding effect and
  3. c) the Abstützkrallen (3, 4) each have two narrow, elongated and edge-shaped contact surfaces (5).

Durch die beiden Abstützkrallen, mit denen die Abstützeinrichtung gegenüber einem Türschweller verkantet zur Anlage gelangt, wird ein Selbsthalteeffekt bei Belastung, d. h. Abstützung, des Spreizzylinders erzielt, der die Abstützeinrichtung am Objekt in Position hält. Dieser Selbsthalteeffekt verstärkt sich in vorteilhafter Weise mit zunehmender Belastung am Spreizzylinder. Die Abstützeinrichtung kann aufgrund der C-Form an beliebiger Stelle des Türschwellers angesetzt werden. Damit ist die Abstützeinrichtung einerseits hinsichtlich des Einsatzortes variabel einsetzbar, gleichzeitig kann aufgrund des Selbsthalteeffekts auf zusätzliche konstruktive Maßnahmen wie z. B. den Einsatz eines Hydraulikzylinders verzichtet werden. Die Abstützkralle weist zwei schmale, langgezogene und kantenförmige Anlageflächen auf. Hierdurch wird zum einen ein Abrolleffekt zur Gewährleistung der Verkantung, zum anderen ein geeigneter Halteeffekt bei Verkantung sichergestellt. Zweckmäßigerweise weist die Abstützkralle jeweils beidseitig zur Abstützeinrichtung Anlageflächen auf, die insbesondere sozusagen spiegelsymmetrisch angeordnet ist. Daraus resultiert der Vorteil, dass die Abstützeinrichtung beidseitig einzusetzen ist.By the two Abstützkrallen, with which the support device against a door sill canted comes to rest, a self-holding effect under load, ie support, the expansion cylinder is achieved, which holds the support means on the object in position. This self-holding effect increases in an advantageous manner with increasing load on Spreizzylinder. The support device can be attached due to the C-shape at any point of the door sill. Thus, the support means is on the one hand variable in terms of the place of use, at the same time due to the self-holding effect on additional design measures such. B. dispensed the use of a hydraulic cylinder. The Abstützkralle has two narrow, elongated and edge-shaped contact surfaces. This will on the one hand a Abrolleffekt to ensure the tilting, on the other hand ensures a suitable holding effect at canting. Conveniently, the support claw on both sides of the support device contact surfaces, which is arranged in a mirror-symmetrical manner, so to speak. This results in the advantage that the support device is used on both sides.

Dadurch, dass die Abstützkralle eine Zahnung aufweist, wird der Halteeffekt noch weiter erhöht. Gleichzeitig wird auch ein besonderer Halteeffekt quer zur Hauptbelastungsrichtung erreicht. Ein Abrutschen seitlich vom Schweller wird hierbei vermieden.The fact that the supporting claw has a toothing, the holding effect is further increased. At the same time a special holding effect is achieved across the main load direction. Slipping sideways from the sill is avoided here.

Zweckmäßigerweise ist die Abstützkralle als Winkelschiene ausgebildet, deren Maul sich zur gegenüberliegenden Abstützkralle öffnet.Conveniently, the Abstützkralle is designed as an angle rail, the mouth opens to the opposite Abstützkralle.

Zweckmäßigerweise betreffen die obigen Ausführungen entweder nur eine der beiden einzusetzenden Abstützkrallen, vorzugsweise aber sowohl die untere als auch die obere Abstützkralle.Conveniently, the above embodiments relate to either only one of the two supporting claws to be used, but preferably both the lower and the upper supporting claw.

Dadurch, dass die obere Abstützkralle einen, insbesondere selbstzentrierenden Anlagebereich für den Spreizzylinder aufweist, kann der Spreizzylinder in geeigneter Weise an der Abstützeinrichtung angesetzt werden.Characterized in that the upper Abstützkralle has a, in particular self-centering abutment region for the expansion cylinder, the spreader cylinder can be recognized in a suitable manner to the support device.

Dieser Anlagebereich wird beispielsweise gebildet durch eine zusätzliche Verstrebung, z. B. in Form eines Rohrs oder eines Stabs, welcher vorzugsweise parallel zur oberen Abstützkralle verläuft und an dem das Ansatzteil des Spreizzylinders eingreifen kann.This investment area is formed for example by an additional bracing, z. Example, in the form of a tube or a rod, which preferably extends parallel to the upper Abstützkralle and on which can engage the attachment part of the expansion cylinder.

Zweckmäßigerweise ist das Ansatzteil des Spreizzylinders entsprechend der Verstrebung, z. B. mit einer Ausnehmung oder Abstufung geformt.Appropriately, the attachment part of the expansion cylinder according to the strut, z. B. formed with a recess or gradation.

Zur Erhöhung des Festhalteeffekts des Ansatzteils des Spreizzylinders am Anlagebereich der Abstützeinrichtung weist der Anlagebereich eine Strukturierung, insbesondere einzelne Rillen auf. Die Rillung bewirkt, dass insbesondere auch ein seitliches (d. h. quer zur Hauptbelastungsrichtung erfolgendes) Abrutschen des Rettungswerkzeugs verhindert wird.To increase the retention effect of the attachment part of the expansion cylinder on the abutment region of the support device, the abutment region has a structuring, in particular individual grooves. The creasing causes, in particular, a lateral (i.e., transversely to the main load direction) slipping of the rescue tool is prevented.

Die Verstrebung und die obere Abstützkralle sind über eine gemeinsame Endplatte miteinander verbunden, wodurch sich eine maximale Stabilität der Abstützeinrichtung im Anlagebereich ergibt.The strut and the upper Abstützkralle are connected to each other via a common end plate, resulting in a maximum stability of the support device in the investment area.

Gemäß einer weiteren Ausgestaltung der vorliegenden Erfindung ist der Abstand der beiden Abstützkrallen zueinander veränderbar, d. h. die C-Form besitzt eine variable Öffnungsbreite. Dies ist insofern vorteilhaft, als der Benutzer die Abstützeinrichtung durch Veränderung der Öffnungsbreite vorläufig fixieren kann, bevor das Rettungswerkzeug, d.h. der Spreizzylinder, angesetzt wird. Auch kann eine gewünschte Beeinträchtigung des Neigungswinkels der Abstützeinrichtung am Objekt vorgenommen werden. Darüber hinaus hat die variable Öffnungsbreite zur Folge, dass Fahrzeugtypen mit unterschiedlichsten Schwellerhöhen mit einer einzigen Abstützeinrichtung erfasst werden.According to a further embodiment of the present invention, the distance of the two Abstützkrallen is mutually variable, d. H. the C-shape has a variable opening width. This is advantageous in that the user can preliminarily fix the support by altering the opening width before the rescue tool, i. the spreader cylinder is attached. Also, a desired impairment of the inclination angle of the support device can be made on the object. In addition, the variable opening width has the consequence that vehicle types with different sill heights are detected with a single support device.

Zweckmäßigerweise ist zur Gewährleistung der Verstellbarkeit der Öffnungsbreite der Rahmen in ein erstes Rahmenteil sowie zweites Rahmenteil unterteilt, wobei die beiden Rahmenteile gegeneinander verschiebbar, aber feststellbar sind.Advantageously, to ensure the adjustability of the opening width of the frame is divided into a first frame part and second frame part, wherein the two frame parts are mutually displaceable, but detectable.

Die Feststellung der beiden Rahmenteile zueinander kann kraftschlüssig beispielsweise durch eine Feststellschraube und/oder formschlüssig durch einen Rastbolzen vorgesehen sein, die bzw. der in entsprechende Vertiefungen oder Löcher eingreift.The determination of the two frame parts to each other can be frictionally provided for example by a locking screw and / or a form-fitting by a locking pin, which engages in corresponding depressions or holes.

Zweckmäßigerweise weist der Spreizzylinder ein der Form des Anlagebereichs angepasstes Endstück (z. B. prismenförmiges Endstück) auf. Das angepasste Endstück ist zweckmäßigerweise so ausgestaltet, dass eine Verdrehbewegung des Spreizzylinders um den Anlagebereich vereinfacht wird. Die Gefahr eines seitlichen d. h. quer zur Hauptbelastungsrichtung erfolgenden Abrutschens soll dagegen vermieden sein.Expediently, the spreader cylinder has an end piece adapted to the shape of the abutment region (eg prism-shaped end piece). The adapted end piece is expediently designed such that a rotational movement of the expansion cylinder around the contact area is simplified. The danger of a lateral d. H. By contrast, slippage transverse to the main loading direction should be avoided.

Der Rahmen 2 umfasst ein erstes Rahmenteil 11 sowie zweites Rahmenteil 12, welche teleskopartig gegeneinander verschiebbar sind, um die Öffnungsweite X der Abstützeinrichtung verändern zu können. Zum Feststellen der Öffnungsweite dienen einzelne Löcher 13 innerhalb des zweiten Rahmenteils 12 sowie eine am ersten Rahmenteil 11 vorgesehene Feststellschraube 14, die in Abhängigkeit von der eingestellten Öffnungsweite in das betreffende Loch 13 am zweiten Rahmenteil 12 eingreift.The frame 2 comprises a first frame part 11 and a second frame part 12, which are telescopically displaceable against each other in order to change the opening width X of the support means can. To determine the opening width serve individual holes 13 within the second frame member 12 and provided on the first frame member 11 locking screw 14, which in dependence of the set opening width engages in the relevant hole 13 on the second frame part 12.

Die obere Abstützkralle 3 sowie untere Abstützkralle 4 sind jeweils als Winkelschiene ausgebildet und weisen eine Zahnung 6 auf. Die Winkelschienen sind hierbei so angeordnet, dass sich deren Maul jeweils zur gegenüberliegenden Abstützkralle 3 bzw. 4 öffnet. Jede Winkelschiene umfasst eine schmale, langgezogene, kantenförmige Anlagefläche 15.The upper Abstützkralle 3 and lower Abstützkralle 4 are each formed as an angle rail and have a toothing 6. The angle rails are in this case arranged so that their mouth opens in each case to the opposite Abstützkralle 3 and 4 respectively. Each angle rail includes a narrow, elongated, edge-shaped contact surface 15th

Im Bereich der oberen Abstützkralle 3 ist eine Verstrebung in Form eines Rohres 8 vorgesehen, welches zusammen mit der oberen Abstützkralle 3 einen gekrümmten Anlagebereich 7 für das (in Fig. 1 nicht dargestellte) Werkzeug bzw. dessen Endstück bildet. In dem Rohr 8 sind Rillen 9 in Querrichtung zum Längsverlauf des Rohrs 8 vorgesehen, um eine zusätzliche Fixierung des (in Fig. 1 nicht dargestellten) Endstücks eines Spreizzylinders zu ermöglichen.In the area of the upper supporting claw 3, a strut in the form of a tube 8 is provided which, together with the upper supporting claw 3, has a curved contact area 7 for the (in FIG Fig. 1 not shown) tool or its tail forms. In the tube 8 grooves 9 are provided in the transverse direction to the longitudinal course of the tube 8 in order to provide additional fixation of the (in Fig. 1 not shown) tail of a spreading cylinder to allow.

Die Art und Weise, wie die erfindungsgemäße Abstützeinrichtung an das Objekt angesetzt wird, zeigen die Figuren 2 und 3. Bezugsziffer 16 zeigt im Querschnitt den Schweller einer Fahrzeugtüre in Schnittdarstellung mit an der Oberseite befindlichem Dichtungsprofil 18 sowie an der Unterseite befindlichem T-Trägerprofil 19.The way in which the support device according to the invention is applied to the object, show the Figures 2 and 3 , Reference numeral 16 shows in cross-section the sill of a vehicle door in a sectional view with befindlichem at the top sealing profile 18 and located at the bottom T-beam profile 19th

Zunächst wird die Abstützeinrichtung mit vergrößertem Abstand der beiden Abstützkrallen 3, 4 über den Schweller 16 gezogen und anschließend gemäß Fig. 3 durch Ineinanderschieben des ersten Rahmenteils 11 sowie zweiten Rahmenteils 12 in Position d. h. in Anlage zu dem Dichtungsprofil 18 sowie dem T-Trägerprofil 19 gebracht und in dieser Position mittels der Feststellschraube 14 fixiert. Hierbei wird die Abstützeinrichtung 1 lediglich fixiert, d. h. es erfolgt kein Einspannen d. h. Festspannen der Abstützeinrichtung auf den Schweller 16.First, the support device with an increased distance of the two Abstützkrallen 3, 4 is pulled over the sill 16 and then according to Fig. 3 brought into telescoping the first frame member 11 and the second frame member 12 in position ie in abutment with the sealing profile 18 and the T-beam profile 19 and fixed in this position by means of the locking screw 14. Here, the support device 1 is merely fixed, ie there is no clamping ie clamping the support means on the sill 16th

Die Position gemäß Fig. 3 ist in einer Gesamtdarstellung unter Einbeziehung des Objekts in Form eines Fahrzeugs 15 in Fig. 4 dargestellt. In dieser Position greift der Spreizzylinder 17 mit seinem Endstück 20 am Anlagebereich 7 des Rohrs 8 der Abstützeinrichtung 1 an. An der gegenüberliegenden Seite des Spreizzylinders 17 liegt dieser am Rahmen des Fensterausschnittes des Fahrzeugs 15 an.The position according to Fig. 3 is in an overall representation involving the object in the form of a vehicle 15 in FIG Fig. 4 shown. In this position, the expansion cylinder 17 engages with its end piece 20 at the contact area 7 of the tube 8 of the support device 1. On the opposite side of the spreading cylinder 17 this is located on the frame of the window opening of the vehicle 15.

Das Endstück 20 des Spreizzylinders 17 ist dabei mit einer spitzen Ausnehmung versehen, so dass die Außenfläche des Rohrs 8 in die Ausnehmung eingreift und ein Verdrehen der Winkelstellung des Spreizzylinders 17 zur Abstützeinrichtung 1 ermöglicht.The end portion 20 of the expansion cylinder 17 is provided with a pointed recess, so that the outer surface of the tube 8 engages in the recess and allows rotation of the angular position of the expansion cylinder 17 to the support device 1.

Wird nun der Stempel des Spreizzylinders 17 ausgefahren, verkantet die Abstützeinrichtung 1 - wie aus Fig. 5 ersichtlich - und bedingt über die beiden Abstützkrallen 3, 4 eine Verkeilung und somit einen Halteeffekt der Abstützeinrichtung 1 am Schweller 16. In dieser Position wirkt die Abstützeinrichtung 1 als wirksames Gegenlager zum Spreizzylinder 17 und ermöglicht ein Aufspreizen des Türausschnittes in der in Fig. 5 gezeigten Art und Weise.Now, if the punch of the expansion cylinder 17 extended, tilted the support device 1 - as out Fig. 5 In this position, the support device 1 acts as an effective counter bearing to the spreader cylinder 17 and allows spreading of the door cutout in the in Fig. 5 shown way.
