Sliding door device.

The invention relates to door devices and in particular on sliding door devices in which the door is not only slidable but can also be moved into the door opening.

There are door devices have been proposed that have a door along the wall of a The vehicle is displaceable in order to release or close a door opening, the door executing a sliding movement in such a way that it is not only transverse across the doorway but also into and out of it. Such doors are below for simplicity referred to as sliding and pivoting doors.

According to the invention, a sliding and pivoting door device is created with a door part which can be moved and pivoted together with a body part is. The device comprises a first guide track carried by a part and a second support guide for supporting the door part relative to the body part via a first trailing part and a linkage or a

binding, which or * which is free from the other part protrudes, wherein the connection further carries a second trailing part, which is of the first trailing part in the Distance is to follow the guideway. One of the guideways is arranged in the pivoted state of the door part in such a way that it is against another than a pivoting movement to open the door reacts, and one of the guideways is in the open state of the door such that it reacts to any movement other than sliding movement of the door part or withstands such a movement.

Preferably, one of the guideways corresponds essentially to the shape of the part carrying it, and the other has guideway while it also coincides with this shape, an end portion which is substantially normal or at right angles to the course said one guide track runs in order to limit the movement to a closing pivoting movement or an opening pivoting movement.

The invention is explained below with reference to the drawing "for example.

6 is a schematic view of another modified sliding and pivoting door device, in which the guideways are carried by the door part.

Figures 7 to Io are schematic views of practical embodiments of sliding and pivoting door devices according to the invention. In Fig. 1, an upper corner at the edge entering the door opening (as opposed to the adjacent edge) of a sliding and pivoting door is denoted by the reference numeral 1. Two door positions A and B are also shown. The door is provided with an inwardly projecting support part 2, which is articulated at a vertical pivot point on an arm k which, in position A, extends outward from an inwardly located point 3, so that the door thereby by means of a trailing part 6 Is carried in a cantilevered manner on a support guideway 5. An upwardly projecting part of the arm k is attached to a roller or other suitable device which is in engagement with a guide track 7. It can be seen that the support guideway 5 is essentially straight and runs along the general line of the body or vehicle body in which a door opening is provided, which is indicated at 8 in a broken representation. The guide track 7 is bent inwards in the direction against the closed position of the door. Both guide tracks 5 «7 are carried in the frame of the vehicle and a suitable opening 9 is provided to allow the inwardly projecting support part 2 during the final closing movement of the

409882/0384

To pick up the door * - ^r

In the lower part of FIG. 1, a section through the lower outer corner of the door is shown and it can be seen that a channel or a guide track Io is formed in the door and is designed in such a way that an upwardly projecting bolt 11 of a joint 12 which can be provided with a roller to reduce friction and which is mounted within the door frame as shown. The joint 12 is spring-loaded in the direction against the two positions shown and it is described in detail in connection with FIG.

With regard to the operation of the sliding and swinging door apparatus according to the simple schematic illustration in Fig. 1 it should be noted that in the position A, the door 1 is substantially flush, located to the side of the vehicle on which the door is mounted, and that the Arm 4, which is pivotably connected to the support part 2 via a vertical pivot point at 3, is in a position beyond a dead center, the dead center being represented by a broken line 13 Drive chain or another device applied to the trailing part 6 in the seal of the arrow 14. The effect of this is that the arm 4 is moved beyond the dead center position 13 when the trailing part 6 crosses the support guideway 5. Such a movement is then accompanied by a movement of the roller or other device which is located perpendicularly above the pivot point 3, namely along the guide track 7 'so that the door is given an outward movement via the support device 2. The edge of the door comes free from the side of the vehicle and the door then moves along the side of the vehicle towards you

409882/0384

Position, for example position B, to be noted istι that during the movement of the upwardly projecting part along the guide track 7 of the arm 4 on it is limited to move clockwise through an angle of just over 9o, assuming is that the rectilinear part of the guide track 7 is located directly below the support guide track 5.

In Fig. 2 the adjacent edge of the door is shown and it is also shown that a further support part 21 is provided, which is carried by a further running part 22 on a further support guide track 23. The further support guide track 23 is bent inwardly in the direction towards the closed position of the door as shown and therefore the door is given a translational movement in the direction towards its closed position. In the lower corner of the adjacent edge of the door, a slot 2k is provided, with which a pin 25 can engage, which is attached below the level of the step 26 on the threshold of the door opening.

It should be noted that, due to the shape of the further supporting track 23, the door at both upper corners is limited to perform a pivoting movement, so that due to the rigidity of the door, its lower corners are also limited to making a similar movement, and the above-mentioned hinge 12 provides a stabilizing effect due to the engagement of its pin or bolt 11 or a roller attached to it with the groove Io in the door. As a result of the spring load on the joint 12, the hinge 12 is pressed inward by spring action in the closed position, and it is in the Open position or in intermediate positions of the door in one Spring-loaded position, which in turn lies beyond the top dead center position in such a way that any thrust force, which is usually applied from the outside of the door, does not lead to the tendency to move the hinge 12 in the direction against the

A09882 / 0384

To press the position it occupies in the closed position of the door.

As a result of the support guideway 23 being shaped in this way, the adjacent edge 27 during the closing process the door led at an angle to the threshold 26, and the slot 24 is guided into engagement with the pin 25. The pin or bolt 25 then forms the Means by which one reacts against outward pressure forces on the door. It is in this context note that even if the pin 25 fails or is misplaced, the door on theirs lower edge still held against outward movement is through continued action of the joint 12, its outward movement is only limited to the pivoting movement of the door.

After the general working principles of the sliding and swing door device have been described, Reference is made to Fig. 3, in which a general embodiment of a suitable embodiment of the support part 2 and the pivot arm 4 is shown are. It can be seen that the arm 4 is articulated perpendicularly to the inner end of the support part 2 * in a suitable manner Is carried out so that a bolting can be done with the'inner or outer surface of a door. The outer end of the arm 4 is articulated on a pin 35 which is carried by a flange 36 of a running part is, which has rollers 37, which are designed in an appropriate manner so that they of the support track 5 can be worn as described above. Furthermore, there is a roller 38 in the guide track 7 Intervention that takes place immediately above the pivoting center of the Support part 2 and the arm 4 is attached. In the drawing, an alternative location 39 is indicated for Guide roller 38, and this allows the selection of a position so that when a predetermined thrust

409882/0384

force on the "door, the door is pivoted out of the doorway can be despite the fact that the arm 4 is in the position is beyond the top dead center position, mentioned above in connection with FIG.

In FIG. 4 this is mentioned in connection with FIG Joint 12 is shown on a larger scale and in greater detail, and it can be seen that joint 12 by means of a spring-loaded plunger 4l in the door frame is spring-loaded in such a way that the swiveled out State of the door of the bolt 11 of the hinge 12 beyond the top dead center with respect to the pivot point 42 of the joint 12 is arranged. It is to be noted that the hinge 12 is mounted in the door frame that it is in the open state and in the closed State of the door does not form an obstructive protrusion in the door opening or in the surfaces of the door. The open one Door division is in Fig. 4 a, and the closed door • division shown in Fig. 4b.

In a modification, the joint 12 can be arranged such that it is with a guide track on the lower edge of the door is in engagement, and this guide track can in turn engage with a holding device, create with the pin 25, for example. The holding device can alternatively be followed by a be formed inside tapered steel part which comes into engagement with the end of the last-mentioned guide track. The steel part is on the vertical surface of the passenger threshold attached.

In the modified embodiment shown in FIG the guideways are on the door. The broken outline 1 represents a door opening and the outline shown in dash-dotted lines FIG. 2 shows the shape of a typical door which is intended to serve as a sliding and pivoting door for the opening 1.

409882/038 4

A securely attached bearing arm 3 is provided on the frame of the opening, with provisions for a perpendicular rotatable spindle 4, which has a small running part 5, a cantilevered link arm 6 and a trailing wheel 7 wearing. The running part 5 is engaged in a reverse Guide track 8 which is mounted within the thickness dimension of the door in such a way that guidance and support is made for the door. The sliding part 7 is in engagement with a support guideway 9, one of which is completely rectilinear guideway is also arranged inside the door and parallel to a surface of the door is. The part 3 protrudes from the plane of the door and the opening, in «richer it in the closed position of the The door rests towards the outside in such a way that it is the running part 5 is made possible to walk around the guideway 8, it being noted that, there is a part at the end of the guideway 8 is bent in a direction at right angles to the surface of the door, and the remainder of the guideway 8 is straight inside the door, while the sliding movement of the door, the spindle 4 outside the Level of opening needs to work. The guideway 8 is provided with an extension Io, which is bent approximately in this way is, as shown, and which runs between spring-loaded rollers 11 to a support and guide device for the edge of the door which is remote from the support part 3. The bend or curvature of the Another part Io of the guide track 8 is such that that of that edge of the door which is adjacent to the support part is, given pivoting movement is carried out approximately also from the other vertical edge of the door.

Although in the embodiment according to FIG not shown, it is provided that the lower part of the door is supported and held in a manner which is similar to the manner described in connection with Figs.

409882/0384

When working de ^. Sliding and pivoting door device according to FIG. 5, it should be noted that when the sliding part 7 is deflected in the direction of the arrow, the arm 6 rotates about the pivot points of the spindle 4, so that due to the fact that the running part 5 initially moves the door in prevents a direction perpendicular to the face of the door, the door first swings out and that afterwards, when the trailing part 5 begins to move around the bend towards the rectilinear part of the guide 8, the sliding movement of the door begins and the door thereafter runs approximately parallel to itself. As a result of the elongation of the guideway 8, the other edge of the door performs a similar movement and the door is disengaged from its lower engagement mechanism. In order to close the door, closing forces are applied to it, and the running part 5 and the guide 7 each move in parallel along their respective guideways until the running part 5 reaches the curved part, whereupon it moves in a direction at right angles to the door in such a way that that the arm 6 moves around the supports for the spindle k , so that the door is given the pivoting movement required for closing.

It will be seen that in the embodiment of Figure 5, the device requires the creation of a support part such as part 3 which projects beyond the surface of the frame 1 outside of which the door is intended to slide. This is necessary in order to enable the guide track 8 to run in the desired position to the spindle k . This part 3, which protrudes from the surface of the frame 1, can be undesirable in certain applications, and with the door device according to FIG. 6 this undesirable feature of the embodiment according to FIG. 5 is to be overcome.

From Fig. 6 it can be seen that instead of the above

409882/0384

- Io -

The protruding part 3 is provided for "pivotably supporting the spindle 4" in a pivoting support device which is arranged within the door frame so that the spindle, now designated by the reference symbol 2k , is covered. The door frame is provided with an opening 32 through which the arm, now designated 26, protrudes outward similarly to the arm 6 according to FIG. 5. In the embodiment according to FIG attached at a location displaced from the center of the spindle 24 outward. In turn, a trailing part 27 is provided which is in engagement with a support guideway 29. The track is designated 28 and it is bent in a direction perpendicular to the surface of the door. Like the guide track 29, the guide track 28 is also mounted within the thickness of the door, however, due to the displacement of the location at which the running part 25 is mounted on the arm 6, the guides 28 and 29 can now be arranged relatively closer together and essentially within the door thickness.

The guideway 29 has an extension 33 »the inward and then parallel to the direction of movement of the door to provide support and guidance for that edge of the door which is remote from the lifting mechanism described above. This extension part 33 serves a similar purpose as the extension Io of the guide track 8 according to FIG. 5 ', however it can according to the fact that it is formed as an extension of the guide track 29, again within the Thickness of the door. As can be seen, it is preferably the support guideway that is extended.

In operation or when using the execution form 6 causes a force applied to the arm 26

409882/0384

Movement of the outer end of the arm, thereby entraining the track 29 and the door to which it is attached. Initially, movement of the door can only take place at right angles to the surface of the door due to the fact that the guide track 28 is also at right angles to the direction of the door, so that the running part 25 performs the necessary limiting action or restricting action. It can be seen that when the guide part 7 is deflected outwards relative to the door frame, the running part 5 is also deflected or bent outwards. However, due to the fact that the runner is displaced a smaller distance from the spindle 2k than the follower 27, the follower or runner 25 moves outward by an amount smaller than the amount or the speed at which or with which the guide track 28 moves outward with the door. As a result of this fact, the length of the end part of the guide track 28, which is bent in a direction at right angles to the surface of the door, must have reduced dimensions compared to the end of the guide track 8, which in an embodiment according to FIG Sliding action is created * This adds to the feature that the entire device can be housed within the thickness of the door.

Since the spindle 2k is also accommodated within the door frame, even when the door is open, there is no need for any parts to protrude inward from the door frame. Furthermore, the creation of the spindle 2k within the door frame enables the spindle to be extended downwards to part of a similar mechanism located on the lower edge of the door such that identical movement is provided at the lower edge of the door. As a result, more stable and more accurate work of the door can be obtained.

409882/0384

If so desired, the extension, for example the extension 33 of the rod 29 or the extension omitting the rod 28 if this is formed as an extension thereof as an alternative, the Door itself are designed so that it has inner discs or wheels around which a wire or the like. Out and connected to the guide member 27 such that the weight of the door rotates downwardly over the mechanism is received or carried, which includes the link arm 26 and is connected to the pull wire.

In FIG. 7, a general arrangement of a swing door device is shown, which represents an extension or expansion of the basic concept which has been described above in connection with FIG. The support arm or the support hinge is denoted by 72 and it is strongly articulated at a pivot point 73 at an intermediate point of a support connection which has an arm 7k protruding freely from the support arm 72 (Krakarm). The link arm 7k is pivotally supported by a support member at 76 which runs along a path 77, the configuration of which is generally rectilinear or at least approximately corresponds to the geometry of the side of the vehicle. A guide arm 75 of the connection is formed integrally with the joint or hinge plate 72 or is fixedly connected to it and is connected to a roller 78 which runs in a groove in a guide track 79. The support guide 77 and the guide track 79 are each carried on the body of the vehicle, and the illustrated end of the guide track 79 is bent inward, similar to the guide track 7 according to FIG. 1. The link arm 7k has an extension 7o which carries a roller with which a rotatable drive cam 80 engages. Since the arms 7k and 75 of the connection are securely connected to one another at the pivot point 73, and the link arm 7k continues to be pivotably connected to the running part at 76

£ 09882/0384

is, causes movement of the barrel part from the illustrated Position to the left under the action of the cam 80 on the arm 7o a movement of the pivot point 73 along a curve which is determined by the geometry of the support guide 77 and the guide track 79. This leads to a Swiveling movement of the door, which is connected to the edge plate 72 is bolted, and when the roller 78 is in the rectilinear Part of the guideway 79 is the pivoting movement completed and the sliding movement continues, to complete the opening of the door.

According to the fact that the link arm is arranged 7k the compound is substantially perpendicular to the supporting guide · 77 in the swing state of the apparatus, the apparatus of the normal or rectangular reaction with the guide track 77 · acts on the one hand the effect, according to react against a swinging out of the door the other hand, the device acts to react against sliding movement as a result of the reaction with the guide track 79 of the roller 78. The pivoting edge of the door is held in this way by the device. The adjacent edge of the door can be held in an appropriate manner, as described, for example, in connection with FIG.

8 schematically shows a general embodiment of a sliding and pivoting door device based on the working principle, as described above in connection with FIG. 5 has been described. It is recalled that in the embodiment of FIG. 5, the support guide and the Guide track are each attached to the door itself and that a connection between the door and a stationary one Bearing arm was made on the door frame. According to FIG. 8, the stationary bearing arm is designated 8l and a swing arm 82 is pivotally connected to it, and this swing arm 82 pivotally carries a vertically mounted Running part 83, over which a support guide 84

409882/0384

is supported by extension members 85 and 86 over the top edge 87 of the door. The guide track is denoted by 88 and a roller 89 is arranged in it, which is attached below the pivot point of the stationary bearing arm 8l. As is described in the embodiment according to FIG. 5, the outer end of the support guide is carried by a suitable guide arrangement, which is designated by the reference numeral 11 in FIG. In the position shown in Fig. 8, the door is swung out and is in the fully open position. Movement of the door to the right by means of an actuating device, not shown X3t, enables the support guide 8k to be carried to the right on the trailing part 83 which is supported via the connection 82 and the support bearing arms 8l. At the point towards the left end of the track 88, the trailing portion 89 moves outwardly with respect to the door and, to allow such outward movement, the support link 82 can pivot inwardly to a point where the linkage 82 is directed substantially at right angles to the door corresponding to the pivoting condition.

In the pivoted state of the door, d. H. in the closed position, the guide track 88 reacts against sliding movement the door, and due to the fact that the connection 82 is perpendicular or super-perpendicular to the Door is, it reacts against the swinging movement of the door, i. H. Pivoting the door to an open position. A suitable pneumatically operated push mechanism may be incorporated into the pivot connection or swing connection 82 to push them in and out of the normal or right angle position to close the door lock or unlock.
