Description

SLIDING AND PIVOTING DOOR FOR PEOPLE TRANSPORTATION VEHICLES The invention relates to a sliding and pivoting door for vehicles for the transportation of persons, the at least one of which can be displaced in the longitudinal direction on a guide element, which can be moved transversely to the plane of the door leaf as part of a square joint, the force of separation of a mechanism for actuating the door in the leaf of the same being applied basically in the direction of the guide element and producing the reaction force of the drive mechanism a torque in a rotating part disposed between the guide element and the door frame, whereby the guide element moves transversely to the plane of the door leaf. A sliding and pivoting door as such is known from EP 0 536 528 Bl, corresponding to DE 41 33 179 A1. In the known device, the longitudinal movement of the door leaf is coordinated with the transverse movement of the door. guide element through a guide rail fixedly attached to the door frame, a guide piece being fixedly attached to the door leaf being in contact with said rail. The moment of recoil of the mechanism acts on a piece called "separator element", which rests on its side again in a fixed support piece to the door frame. These multiple supports, guides, fixings and, therefore, references between the mechanism of the door leaf itself and the corresponding mechanism guides on the one hand and on the other hand fixed parts to the frame of the door, make the previous construction and if installation and adjustment not comfortable and laborious. It should not be forgotten that in addition to the mentioned parts, a door tree tube must be provided for each leaf of the door and coordinate with its rotation with the drive mechanism, in order to guide the door leaf both in its upper area and in its lower area, since the part mentioned as a guiding element in the previously known solution has purely support functions and the guide of the door leaf is made therein exclusively by the door shaft tube, its rotating arms and the corresponding rails . In the previously known solution, the special choice of the square joint also results in the problem that the door can also be opened in a closed state with a drive without current, if the corresponding forces act on the door leaf, which can occur, for example, during acts of vandalism, but also by normal vibrations during driving or by elderly or weak people who rely on the door leaf, but should be avoided for safety reasons. For this reason, the known solution provides a special locking mechanism, which requires another fixing point in the door frame, which must be adjusted precisely. All of the above contributes to the fact that the sliding and pivoting door has not been applied until now in practice. The invention has the purpose of avoiding the disadvantages of the known solution and creating a sliding and pivoting door that can be installed and adjusted simply and quickly and that in a preferred embodiment is also secured without locking mechanism against unintentional opening. For this purpose, it is envisaged according to the invention that the square joint is a parallelogram joint, rotating arms being formed in the body as rotating discs, also the mechanism running essentially parallel to the guide element and the driving arms for pivoting of the door shaft tube, and that the coordination of the longitudinal movement of the door leaf with the transverse movement of the guide element is effected by a pivoting fork about an axis fixed to the body, being in contact with said fork by a On the other hand, a guide element is fixedly connected to the door leaf and on the other hand it is inserted with a guide plug into a guide groove of the guide element. In this way, the entire movement mechanism for the sliding and pivoting door is connected to the body only through the two rotating disc axes and the pivot fork axle, in embodiments of the invention, there is also a counter-support for a spring acting on the rotating fork and a stop for the rotary movement of the rotating discs in the closed direction, all of these connections to the body being provided on a single profile, or Well, a mounting disc, so that the installation of the mechanism completely preassembled and preset in the body can be done by assembling a single piece, namely the carrier profile, or the carrier disc. With the elimination of the guide rail fixed to the body, a significant reduction of the components is obtained, which is provided in the area that always places little space at the disposal of the body, above the door support, and thus an access clearly facilitated for purposes of maintenance and inspection. In the following, the invention is illustrated in more detail with the aid of the drawing. They show: Figure 1, a schematic top view of a sliding and pivoting door according to the invention, in a closed state. Figure 2, the sliding and pivoting door of figure 1 in the open state. Figure 3, the coordination mechanism according to the invention with the door closed. And Figure 4 the mechanism of Figure 3 in the open state of the door. Figure 1 shows a sliding and pivoting door with two door leaves 1,2 and a door activation mechanism referenced in its entirety as 3. Door activation mechanism means all components that are not fixed or fixed rigidly with the door leaf neither fixedly nor rigidly with the body 4. The components that are movably articulated on the door leaf and / or on the bodywork, are part of the mechanism for activating the door. The door leaves 1,2 slide, as can be seen in the conjunction of figures 1 and 2, on a guide element 5 type telescope, which in the course of the opening movement of the door performs a normal movement with respect to the plane of the leaves of the door. This transverse movement is possible by the pivoting of a parallelogram joint, which is composed on one side by the guide element 5, on the other by two rotating discs 6 and finally by the parts of the body that are located between the axes of rotation 7 of the rotating discs 6. On the rotating discs 6 the mechanism itself is also supported, which runs essentially parallel to the guide element 5, so that it also forms with the axes of rotation 7 an articulation in parallelogram with respect to the body and in the course of the opening movement makes a pivoting (translatory) around said axes of rotation. In the example shown, the mechanism 29 consists of an electric motor 8, a spindle 9 and a base carriage 10 that moves on rollers, the carriage being in contact with the door leaf by means of an actuating arm 11. The introduction of force it takes place in an arm 12 arranged in a fixed and rigid manner (as opposed to the arm arranged pivotably or pivotably) with respect to the door leaf 2. As can be seen particularly in figure 3, the arm 12 carries a stopper or, a roller 13 that is placed in the recess between the teeth of a rotary fork 15. Said fork can rotate about an axis 16 fixed to the body and carries on its side a guide finger 17, which is inserted in a slot 18 of a guide disc 19, which is fixedly and rigidly connected to the guide element If to open the door mechanism 29 is activated, the motor 8 sets the spindle 9 in motion and the base truck 10 loads with pressure the arm of action 11 and thus tries to move the door leaf 2. The foregoing is prevented by the guide element 13, which is fixedly arranged with the door leaf and inserted into the pivoting fork 15, so that due to the reaction force of the mechanism moves the entire mechanism 29 to the left with respect to the body (shown in the drawing) and rotates around the axis of rotation 7 in a clockwise direction. As a result of this rotational movement of the rotating discs 6, the guide element 5 also rotates., it reaches its exit movement, taking with it its longitudinal slot 18 the guide finger 17 of the rotating fork 15 and thus produces the rotation of the rotating fork 15, whereby after the complete movement of the guide element 5 the roller guide 13 of the door leaf 2 leaves the area of the teeth 14 of the rotating fork 15 now rotated, which allows the mechanism to move the door leaf 2 through the drive arm 11 in the direction of opening along of the guide element 5. The coordination of the movement of the second door leaf 1 preferably takes place through a surrounding cable or a toothed belt or the like, the door leaf 1 being articulated in one of the two branches dragged, the leaf of door 2 in the other, so that it is ensured that both door leaves are always positioned symmetrically with respect to the plane of symmetry 20. In the preferred variant shown, the guide fork 15 is loaded in such a manner with a spring mechanism 21, which under the action of said mechanism is always pressed towards one of the two possible end positions. In this way, it is ensured that in the case of vibrations or the like with the door open, the pivoting fork does not leave the angular position shown in figure 4, whose preservation is necessary so that when closing, the guide plug 13 of the wing of the door 2 return to the area of the teeth 14 and allow a closed as it should of the door. In the situation of the fork mechanism shown in Figure 3, which represents the closed state of the door, the spring mechanism 21 supports the conservation of the closed position, which, as illustrated below, is carried out in the first place. Instead of the spring mechanism 21, it is also possible to provide a torsion spring in the area of the shaft 16 fixed to the body of the rotating fork 15, which presses it to the position which is equivalent to the open state, which is shown in figure 4. The guidance of the door in the floor area and the reliable conservation of the door lock, also in the case of free-force driving, is carried out in accordance with a Preferred variant of the invention in the following manner, shown in Figure 1: In addition to the aforementioned components, drive arms 22, which are inserted into arms, are connected with the rotary discs ß. positioners 24 arranged fixed in terms of rotation in the door shaft tubes 23. When the door is opened and thus when the rotating discs 6 are turned, the door shaft tubes 23 are also rotated. These carry in the area of the floor of the door the body, rotating arms 25, which are introduced with their free ends, by means of rollers or the like, into guides 27 of the door leaves 1, 2 and guide and support said door leaves in the lower area. It is also advantageously provided, as can be seen in FIG. 1, that the actuating arms 22, in the closed position of the door, are placed on the side with respect to the axes of rotation 7, which when exerting pressure on the door leaves 1, 2 in the direction of the outgoing movement, applies a torque to the rotating discs 6, whereupon they are loaded in the direction of closed movement. As seen in the example, the above is achieved by a neutral position, or a situation on the dead center, in which during the course of the closed movement the driving arms 22 are moved beyond the axes 7. This measure, as is known, makes necessary the provision of an emergency driving device, which according to the invention acts either on the drive mechanism or on one of the rotating disks 6 in the direction of movement opening and thus allowing an opening of the door even in the case of the motor without power 8. In a preferred embodiment but not illustrated, it is possible to facilitate the achievement of the position on the dead center by a spring, which acts on the door shaft tube or the rotating disk or another component (or between two components) of the door drive mechanism, in Closed direction. This is particularly advantageous in the case of emergency operation if the engine does not work. The invention is not limited to the illustrated example, but can be modified in different ways. Thus, it is possible to use another linear motor in place of the spindle motor or to modify the position of the rotary fork 15 by means of a kinetic inversion, if a stopper, a mandrel, a finger or the like and the like are attached to the guide element 5 for example. The rotating fork 15 is provided with a slot-like guide, correspondingly shaped. In the example shown, the actuating arm 11, or its point of attack on the arm of the door 12, is chosen in such a way that during the opening or closing movement it varies as little as possible on both sides of the door. direction of the linear drive. In special installations it is obviously conceivable to arrange the point of attack closer to or further from the door leaf 2, so that the arm 11 always lies only on one side of the driving direction. For special cases it can also be considered to join the drive arm 11 fixedly to the rotation with the base carriage 10 and provide a guide in the form of a groove in the arm of the door 12, along which the point of movement moves. attack of the driving arm 11 during the opening or closing movement. In the figures it can be seen that the end of the closing movement is given in an adjustable manner by a stop 28. This stop does not need to be fixed to the body, as shown in the illustrated example, but it can also be replaced by a limit adjustable swivel between the drive mechanism 29 and the rotating disk 6 or between the guide element 5 and the rotating disk 6 or other parts that are relatively movable relative to each other in the course of the opening and closing movement. As can easily be seen in FIGS. 1 and 2, all the parts fixed to the bodywork and coacting with the mechanism of the door 3, can be easily foreseen on a mounting disc or a thin and space-saving mounting profile , so that in the end only this profile or mounting disc must be joined to the body to install the entire mechanism 3. The actuating arms 22, which constitute the union to the door shaft 23, in such a case they are formed preferably adjustable in their length, to compensate for possible tolerances between the position of the door tree tubes and the entire drive mechanism 3.
