Description

Suspension device for the wings of vehicle doors The invention relates to a suspension device for the wings of vehicle doors, whose rear edge from the closed position can initially be reset about a vertical axis and then can be moved approximately horizontally along the fixed outer wall, consisting of swivel arms that are attached to the vertical post of the fixed door frame, on which the wing is pushed along, rotatably mounted about a vertical axis and by means of hinge bolts on roller carriages mounted horizontally on the door leaf are articulated, as well as arranged on the opposite wing edge in the closed position, guide means and a device guided in a curved guide rail, which tries to push the sash out of the fixed door frame when it is opened.

In a known suspension device of this type, there is Device that pushes the sash out of the fixed door frame when it is opened seeks, from one pen. A spring represents a part that is constantly in operation is subject to variable stress, thus fatigued and after some time may break. The breakage can have the effect, especially in the case of icing, that the door can no longer be opened. For those applicable in vehicle operation In such a case, the vehicle would have to be removed from the strict safety regulations Be put into operation. There is also the fact that the spring of the known type the door with a shock unexpected for the passenger when the lock is released opens jerkily. The door handle grasped by hand can then with an unfavorable setting put a compression on the wrist. After all, the spring must close when it closes the door must be tensioned again. Above all, this means increasing the clamping force just towards the end of the closing movement. However, experience shows that vehicle doors are closed by an initially exerted powerful impulse, the last being closed Movement of the door leaf under the effect of the kinetic energy imparted to it accomplishes. It is precisely during this last phase that the spring settles on the door according to the known design of the movement opposite with the result that the door many times won't snap into place.

The invention is based on the object of a suspension device of the type described at the outset to overcome the shortcomings explained above free is. According to the invention, the device consists of one on the wing side for this purpose End of a swivel arm arranged cam to which at the beginning of the opening movement a stop attached to the wing is supported so that the swivel arm around the vertical Axis is pivoted outwards.

With a suspension device designed in this way is a Spring avoided and the structure significantly simplified, because the cam can without further created at no additional cost by forming an extension on the swivel arm and the stop can consist of a piece of flat iron that is simply attached to the door leaf is welded on. The cam and stop are also indestructible Parts that are subject to a certain amount of wear and tear, thereby reducing their effectiveness but not forfeit. Finally, the opening takes place smoothly, and the device does not generate any forces that oppose the closing of the door.

The suspension device according to the invention works properly when Cam and stop really meet when the door is opened. Stuck the door by tilting before the cam hits the stop, then these parts remain ineffective. However, this is avoided if according to the preferred one Implementation of the invention, the pivot pins connecting the swivel arm to the roller carriage are united to a continuous wave, on which two at a distance from each other Pinions are attached that mesh with racks attached to the wing. It acts it is a measure that is known for pivoting sliding doors.

The drawing is used for further explanation. It shows F i g. 1 one Door with a hanger in view from the inside and in a relatively small size Scale with omission of details, F i g. 2 one of the F i g. 1 corresponding Representation on a larger scale with an advanced middle section, FIG. 3 one Section along line III-111 in FIG. 2 with the door closed, F. i g. 4 one of the F i g. 3 corresponding section with the door open, FIG. 5 one the F i g. 3 corresponding section shortly after the start of opening, F i g. 6 one Section along line VI-VI in F i g. 2, fig. 7 shows a section along line VII-VII iii F i g. 2, fig. 8 shows a section along line VIII-VIII in FIG. 2, fig. 9 a section along line IX-IX. in Fig. 2, fig. 10 a section along the line X-X in FIG. 2 with the door closed and F i g. 11 one of the FIGS. 10 corresponding Cut after opening.

The wing l of the swivel sliding door shown fills in closed Position according to FIG. 1 to 3 a door frame 2. It is then flush with a Area 3, which forms the outer skin of vehicles. For the sake of simplicity, the wing is drawn as a flat plate. But it is easily possible to adapt to him to give the shape of the vehicle a curved shape.

To open the rear edge 4 of the wing 1 is first shown in FIG. 5 lifted completely out of the door frame 2, while the front edge 5 participates in this movement only to a small extent. This is followed by a shift of the entire wing 1 to the side, specifically in the sections according to FIG. 3 to 7 to the right. The two movements partially overlap. They come about through the guidance and control means described below. Near the front edge 5 sits on the wing 1 a support arm 6, which according to FIG. 8 is cranked. Between two parallel legs 7 of this arm, a carriage 9 is rotatable about a vertical axis on pin 8. This carriage runs on four rollers 10, some of which are shown in FIG. 2, partly in FIG. 3 can be seen on a slightly curved guide rail 11, which is circular in cross section. The support arm 6 has a protruding arm 12; which carries at its end a roller 13 which runs in a guide rail 14 of U-shaped cross-section. Since the arm 12 is firmly connected to the wing l and the position of the axes of rotation of the pins and the rollers 13 is determined on the one hand by the fixed spacing of the arm 12 and on the other hand by the guide rails 11 and 14 for each position, is also due to the so The guide elements described far determine the movement of the door leaf when opening and closing. The relatively strong curvature of the guide rail 14 at point 15 causes opening at the beginning, that is, at the transition from FIG. 3 in FIG. 5, a left turn of the arm 12 around the pin 8 and a similar turn of the door leaf. At the same time, the shifting of the wing to the right begins, that is to say the movement of the carriage 9 on the guide rail 11. The wing is therefore at the beginning slightly inclined towards its basic position. This inclination is, however, during the transition into the fully open position according to FIG. 4 slowly reversed so that the door is parallel to surface 3 at the end.

The guide means described so far are arranged near the top edge of the door. However, the wing is also given a guide similar to the carriage 9 and the guide rail 11 at the lower edge. Taking into account the different spatial conditions in the lower area of the door, the elements of the guide are designed somewhat differently. A carriage 16 runs with rollers 17 in a rail 18 of U-shaped cross-section and has a laterally projecting extension 19 with which it is articulated in the joint 20 to an arm 21 which in turn is attached to the wing 1. Functionally, the joint 20 corresponds to the joint point formed by the pin 8. The rail 18 is designed in such a way that it guides the wing on the same path as the guide rail 11 with the aid of the carriage 9.

Although the door leaf movement is kinematic by the means described is set, it is generally necessary to move the door leaf in the area of its rear edge 4 to support. For this purpose, a bearing 23 is arranged on the door frame 2 vertical axis 22 rotatable on which a short pivot arm 24 is attached. This Swivel arm is according to FIG. 9 designed as a hollow profile body that extends over extends almost the entire height of the door. In it is a continuous hollow shaft 25 stored, at the ends of which two bearing blocks 26 are rotatable in ball bearings. On these The wing l is slidably guided above and below by two rollers 27 each.

When the door is closed, the swivel arm 24 is shown in FIG. 3 inside panned. In the described first phase of the opening movement, the pivots Swivel arm 24 outwards into the position according to FIG. 4 and 5 and persist in them during the subsequent movement of the sash into the open position. A Axis 22 is not driven.

In the case of doors of great height and width, there is a risk of edging even if the guide means described are present. As indicated at the outset, this is understood to mean an undesired rotation of the wing about an axis that is perpendicular to the plane of the wing, that is to say about an axis that is shown both in FIG. 3 as in FIG. 8 is parallel to the plane of the drawing and perpendicular to the contours that indicate the wing. The edging comes about through the inevitable elastic changes in shape in the wing and in the guide means as well as through inevitable play. In order to eliminate the edges, two horizontally extending toothed racks 29 and 30 are fastened on the inside of the wing 1 near the upper and lower edges. Pinions 31 and 32 mesh into these racks, both of which are firmly seated on a shaft 25.

If the pinion is missing and the door is edging, this means that the racks 29 and 30 move at different speeds. By the pinion seated on a common shaft eliminates any difference between the speeds the racks excluded. Edging of the door leaf is therefore also impossible made.

The usual handles 33, 34 on the inside are used to handle the door and on the outside according to FIG. 1 and 7. In particular with the help of the handle 33, to open in the direction of the arrow in F i g. 7 is moved is on the wing simultaneously exerted a torque and a force tending to the wing to move in the way that his leadership dictates. The handles 33 and 34 are connected by a linkage to a bolt 35, which when the door is closed engages in an indicated trap 36. When the handles are operated, the bolt goes out pulled out of the trap.

By the arm 12 in connection with the guide rail 14 is how described, the wing 1 at the beginning of opening a rotation about the pin 8 and the joint 20 granted. Because of the long lever arm that embodies the wing, this rotation by a relatively low, near the trailing edge 4 across the wing acting force can be prevented, for example by a Person leaning against the wing from the outside. This is shown in FIG. 10 and 11 indicated facility excluded. On the pivot arm 24 is a with a Roll 37 reinforced cam 38 formed, which when the door is closed in the position according to FIG. 10 lies next to a stop 39 formed on the wing 1. Will the The door is opened by the movement of the sash, which begins immediately to the right of the pivot arm 24 by means of the stop 39 and the cam 38 a clockwise rotation issued, with the wing through direct application of force via the bearing block 26 at the rear edge 4 is pressed outwards and so any resistance is easy overcomes. If the sash lifts out of the frame when it is opened, it moves away according to FIG. 11 the stop 39 out of the area of the cam 38 and prevents the further Don't postpone.
