Description

PIVOTING DOOR WING FOR VEHICLES The invention relates to a pivoting door wing for vehicles, particularly for motorized vehicles, which is pivoted inwards with the help of pivoting arms, which are driven by a rotating column, and which is provided at its lower horizontal edge of a sealing strip. According to the disclosure of DE 80 09 490 Ul, it is provided that the sealing strip is arranged on the wing of the pivoting door in a rotatable, particularly foldable or foldable manner, and that the lower pivoting arm is arranged below the folding point of the shutter slat. This sealing strip does not pass through the total width of the door wing, but only through that part which, during the pivoting movement, reaches the path area of the lower pivoting arm, otherwise the highly rotated sealing strip hits it with the tube. of the door tree. In the remaining area of the door wing, a seal is provided in the form of a brush, which also constitutes a stop for the sealing strip. The sealing strip itself is constituted according to the only embodiment presented and not illustrated in more detail, by a metal profile flexibly hinged by a rubber band in the form of bone in its cross section, in a corresponding profile at the lower edge of the door. In the course of the opening movement of the door wing, the sealing strip collides with the pivoting arm, which leads to the bending of the rubber band, whereby the sealing strip moves from its essentially vertical hermetic position to a position essentially horizontal, highly rotated with the door open. In its practical application, this construction presents a series of disadvantages, with the rubber band absorbing the flexure and the sealing strip often loaded with friction, subjected in the same way to rapid wear. To this it is added that the conformation in several pieces of the whole shutter device makes necessary a precise adjustment not only in the initial construction, but also in subsequent maintenance and replacement work, which is not very comfortable in the area of the lower end of the construction. the door leaf. The invention seeks to assist in this respect and proposes for this purpose a continuous sealing strip, made of elastic material of rubber or plastic, which is rotatably fixed at the lower edge in the closed position of the wing of the door. With this measurement, not only the axis of rotation, which is preferably formed as a weak point in the material of the sealing strip, is displaced towards the clean and hot side of the door, where it is in better possibilities of resisting the mechanical influences and weathering, but in a particular conformation it is also possible to limit the angle of pivoting to approximately 45 °, which represents with respect to the state of the art a division between two of said angle of pivoting and contributes essentially to the improvement of the duration of the shutter strip. Since the latter is formed in one piece and preferably extends over the entire width of the door wing, replacement is also essentially simplified. The invention is illustrated in more detail with the help of the accompanying drawings. Figure 1 shows a cut through a pivoting door wing shaped according to the invention, in closed position. Figure 2 shows a top view of a pivoting door shaped according to the invention, wherein the closed position is indicated with continuous lines and the open position with dotted lines. And Figure 3 shows a variant according to the invention of Figure 1. As can be seen in Figure 1, at the lower end of a door wing 1 is fixed a sealing strip 3 of rubber or plastic, for example by a fixing strip 2. In the illustrated example, the fixing is carried out by means of a counter-plate 4, after which the whole assembly composed of shutter rail 3, counter-plate 4 and fixing rail 2 with few screws or rivets is fixed to the lower end of the wing of door 1. The wing of door 1 is moved in a way that it can be seen in figure 2, by means of a door shaft tube 5 and pivoting arms 6 arranged at the lower and upper end, of which only the lower end is illustrated: In the closed position of the wing of the door 1, this closes an opening in the vehicle, indicated by a frame 7. By means of a wing or insert 8 above the sealing strip 3 (not shown in FIG. 1), the wing of the door 1 is connected in an articulated manner to the pivoting arm 6. By opening the wing of the door 1, its main closing edge 9 reaches the opening area in which the secondary closing edge 10 is located in the closed position, this in turn moves almost linearly and normal to the surface outside of the vehicle towards the inside of it. In the course of this movement, the door wing 1 passes over the pivoting arm 6, which is possible due to the folding of the sealing strip 3. Preferably, the lower pivoting arm 6 presents at least in the area that comes in contact with the sealing strip 3, a cross-sectional shape, which facilitates the pivoting of the sealing strip 3, as can be observed in figure 1. Moreover, the surface of the pivoting arm 6 is constituted in this zone by a material that reduces friction and it is preferably provided with ribs or slats fastened, glued, screwed or fixed in some other way and which act as a guard rail, which are shaped as wearing articles and protect the pivoting arm 6, or its coating against the wear. In the same way, elements that increase the planing coefficient or are already provided during manufacture are preferably fixed on the sealing strip 3 in the area that comes into contact with the pivoting arm 6. As can be seen in figure 1, the sealing strip 3 according to the invention is rotated only approximately 45 °, to completely exit from the movement zone of the pivoting arm 3, which represents a division between two of the angle of rotation with with respect to the state of the art and represents an overproportional reduction of the corresponding wear and the requirement in the area of the axis of rotation. According to FIG. 1, the door leaf 1 is formed with an outer projection 11, which constitutes a limit of the possibility of rotation of the sealing strip 3. In the example shown, the sealing strip 3 is provided with an additional lip 12. , which is disposed on one side of the fixing strip 2, when the door leaf 1 takes the closed position and thus also has as a target a limit of the turning movement of the sealing strip 3. As shown in figure 1, the The contralist 4 is preferably folded or flanged, to produce a uniform distribution of the deformation of the fixing lip 15 of the sealing strip 3 during the turning movement, thereby further increasing the duration of the sealing strip 3. The variant according to the figure 3 shows a one-piece conformation of the fixing strip 2 and of the counter-plate 4 in the form of a fastening profile 16, which is connected (in a manner not shown) to the wing of the door 1. In this embodiment, the sealing strip 3 carries a guard strip 17, which can also be formed by short sections and has a low coefficient of friction, particularly with respect to the duplication 18 of the pivoting arm 6. The guard strip 17 preferably slides on the sealing strip, as it slides into the holding profile 16 in the variant according to FIG. 3. The invention is not limited to the illustrated examples, but can be modified in various ways .

For example, the fastening strip 2 can be placed in a recess of the wing of the door 1, to close level with the inner side of the wing of the door. Of course, a door equipped according to the invention can also include two door wings. The sealing strip 3 consists of an elastic rubber material, usually used for the sealing of vehicle doors, such as rubber, synthetic or natural rubber, or plastic, etc. and eventually it can be reinforced. As materials for the fastening strip 2, the contralayon 3, or the fastening profile 16, aluminum, optionally as continuous casting profile, can be used; for the contraliston 3 under certain conditions also stainless steel. The guard strip 17 can be made of thermoplastic polyester or polyamide, the duplication 18 can be made of polyamide or also stainless steel. However, knowing the invention and the corresponding requirements, the expert in the area of construction of vehicle doors can use at any time other materials that seem appropriate.
