Abstract

The car door (1) hinge mechanism includes an arm which, on the door being opened, lifts the door outwards and forwards during the outward rotational movement. The system provides more access space than a conventionally hung door. The door fits into the door opening so that it is flush with the surrounding bodywork (2). There are two links (3, 4) each with a pivot at each end to form a parallelogram linkage to cause the hinge end of the door to swing well clear of the bodywork. USE/ADVANTAGE - Hinge mechanism on car door lifts door outwards and forwards, allowing use of single large door on either side of vehicle.

Description

Die Erfindung gehört zum technischen Gebiet des Automobilbaus, Sparte Karosseriebau. Bei allen mir bekannten Automobilbaufirmen werden die Autotüren, abgesehen von Spezialausführungen, an der Vorderkante mittels Scharnieren dicht an die Karosserie angelenkt. Dies führt dazu, daß die Türen, wenn sie sich nur wenig öffnen lassen, wie zum Beispiel in engen Garagen oder Parkplätzen, nur einen geringen Spalt zum Stellen der Füße freigeben, so daß man oft nur mit großen Anstrengungen das Ein- und Aussteigen bewältigen kann. Je breiter die Tür, um so enger der Stellraum für die Füße. Dies und verkehrstechnische Gründe (Ausladung der Tür) bedingen, daß Autotüren kaum breiter als 1,00 m ausgeführt werden und für die hinten Mitfahrenden weitere Türen vorgesehen sind. Der Erfindergedanke beruht nun einfach darauf, daß die Türen um ihre senkrechte Ebene geschwenkt werden, d. h. die Vorderkante von der Karosserie weg und die Hinterkante zur Karosserie zurück. Damit wird größere Freiheit für die Füße erreicht, und die Türen können so breit ausgeführt werden, daß Fondtüren nicht mehr notwendig sind. Die Zeichnung Blatt 3 veranschaulicht die Gedanken nochmals. Fig. I zeigt eine Tür von 1,00 m Breite (gestrichelt) und eine Tür von 1,40 m Breite (Striche durchgezogen), beide geschlossen. Die 1,00 m breite Tür ist mit Scharnieren dicht an der Karosserie angelenkt, die 1,40 m breite Tür mit dem zum Patent angemeldeten Scharnierarm. Fig. II zeigt die Verhältnisse, wenn beide Türen nur 40 cm weit geöffnet sind. Es ist deutlich zu erkennen, wieviel mehr Platz die mit dem Scharnierarm angeschlagene Tür beim Ein- und Aussteigen in engen Räumen freimacht. Fig. III zeigt die Verhältnisse bei 80 cm Öffnungsweite. Auch hier ist noch ein Vorteil für die mit Scharnierarm angeschlagenen Tür zu erkennen. Der Scharnierarm selbst stört die Fußfreiheit nicht, da nur einer pro Tür nötig ist, und er in ca. 40 cm Höhe über dem Boden des Autos am Türrahmen angeschraubt werden kann. Die strich-punktierten Linien zeigen, daß sich die Verhältnisse auch bei einer 1,60 m breiten Tür wenig ändern, außer daß noch mehr Platz für die hinten Einsteigenden vorhanden ist. The invention belongs to the technical field of automobile construction, body construction division. In all of the automobile manufacturers I know, the car doors, apart from special designs, are hinged close to the body by means of hinges. As a result, if the doors can only be opened slightly, such as in narrow garages or parking lots, the doors leave only a small gap for placing the feet, so that it is often difficult to get in and out of the doors . The wider the door, the narrower the foot space. This and traffic-related reasons (projection of the door) mean that car doors are hardly wider than 1.00 m and that additional doors are provided for those traveling behind. The inventive idea is simply based on the fact that the doors are pivoted about their vertical plane, ie the front edge away from the body and the rear edge back to the body. This gives greater freedom for the feet, and the doors can be made so wide that rear doors are no longer necessary. The drawing sheet 3 illustrates the thoughts again. Fig. I shows a door of 1.00 m wide (dashed) and a door of 1.40 m wide (dashes solid), both closed. The 1.00 m wide door is hinged close to the body, the 1.40 m wide door with the patent-pending hinge arm. Fig. II shows the situation when both doors are only opened 40 cm. It can be clearly seen how much more space the door hinged with the hinge arm frees up when entering and exiting in confined spaces. Fig. III shows the conditions at 80 cm opening width. An advantage for the door hinged with a hinge arm can also be seen here. The hinge arm itself does not interfere with the legroom, since only one is required per door, and it can be screwed onto the door frame at a height of approx. 40 cm above the floor of the car. The dash-dotted lines show that the conditions change little even with a 1.60 m wide door, except that there is still more space for those entering the back.

Der Erfindungsgedanke läßt sich in 2 Ausführungen verwirklichen, wie die Zeichnungen Blatt I und Blatt II darlegen.The idea of the invention can be realized in two versions, as the drawings on sheets I and II show.

Ausführung A - Zeichnung Blatt IVersion A - drawing sheet I

Der Scharnierarm besteht aus einem breiten U-förmig gestalteten Hebel aus Blech, der an beiden Enden in Böcken drehbar gelagert ist. Ein Lagerbock wird an der Tür, der andere an der Karosserie (Türrahmen) angeschraubt. Dieser Hebel trägt die Tür. Er muß breit ausgeführt werden und gut gelagert sein, um die Kippkräfte der Tür aufzufangen. Ihm zugeordnet ist ein leichterer zweiter Hebel, der an den Enden ebenfalls drehbar an den Böcken gelagert ist. Er schwenkt die Tür um die senkrechte Ebene, das heißt die Vorderkante von der Karosserie weg und die Hinterkante zur Karosserie zurück. Die Drehpunkte beider Hebel und der Lagerböcke müssen zusammen ein Trapezoid bilden, im Extremfall ein Parallelogramm. Der Öffnungs­ vorgang der Tür hängt von der Lage (Zuordnung) der Drehpunkte ab. Siehe hierzu auch Zeichnung Blatt III.The hinge arm consists of a wide U-shaped lever made of sheet metal, which is rotatably supported in trestles at both ends. One bracket is on the door, the other on the body (door frame) screwed on. This lever carries the door. It has to be wide and be well stored to absorb the tilting forces of the door. Associated with it is a lighter second lever, which at the ends is also rotatably mounted on the trestles. He swings the door around the vertical plane, i.e. the front edge of the Body away and the rear edge back to the body. The pivot points of both levers and the pedestals must be together form a trapezoid, in extreme cases a parallelogram. The opening The process of the door depends on the position (assignment) of the pivot points. See also drawing sheet III.

Ausführung B - Zeichnung Blatt IIVersion B - drawing sheet II

Dieser Scharnierarm besteht aus einem breiten als Gehäuse ausgebildeten Hebel, der die Autotür aushebt. Er ist an beiden Enden in Böcken drehbar gelagert, wovon einer an der Tür und der andere an der Karosserie festgeschraubt wird. Das Schwenken der Tür um die Senkrechte besorgt eine in den Hebel eingebaute Schwenkvorrichtung. Sie besteht aus drei Segmenten mit Verzahnung, wovon 2 gleiche mit den Lagerböcken an Tür und Karosserie fest verbunden (verschweißt) sind, während das mittlere Segment drehbar gelagert sein muß. Die Lage des Drehpunktes bestimmt den Grad der Rückschwenkung. Wird er in die Mitte des Hebels gelegt, das wäre nach Zeichnung a gleich b, dann würde die Tür parallel zur Karosserie geführt werden. Ist der Drehpunkt des Segments türseitig verschoben, das wäre nach Zeichnung a kleiner als b, dann ergibt sich eine Schrägstellung der Tür zur Karosserie entsprechend dem Erfindungsgedanken.This hinge arm consists of a wide housing Lever that lifts the car door. It can be rotated in trestles at both ends stored, one on the door and the other on the body is screwed tight. The swing of the door around the vertical worried a swivel device built into the lever. It consists of three Serrated segments, 2 of which are identical with the bearing blocks on the door and body are firmly connected (welded), while the middle segment must be rotatably mounted. The location of the fulcrum determines the degree of swing back. Will he be in the middle of the Lever, that would be equal to b according to drawing a, then the Door parallel to the body. Is the fulcrum of the Segment shifted on the door side, that would be smaller according to drawing a than b, the door is inclined to the body according to the inventive concept.
