Description

The present invention relates to a door assembly comprising a fixed frame and a relative to the frame tiltable, parallel storable and displaceable in the parked position along a direction sliding wing of a door, a window or the like, wherein the wing coupled by means of upper and lower Ausstellarmen to the frame is and is guided displaceably in the direction of displacement by means of a serving for load dissipation drive.

Door arrangements of the type mentioned are known from the prior art. Such door arrangements are, for example, used as terrace or balcony doors, wherein the wing, starting from a closed, located in contact with the frame position tilted relative to the frame or parked in parallel and can be opened by moving.

Such a door arrangement is, for example, from the DE 32 34 677 A1 known. A disadvantage is the threshold arranged in the region of the floor, which must be exceeded when the door is opened when passing the door arrangement. This threshold is a tripping hazard for pedestrians and an obstacle that is difficult or impossible for wheelchair users to overcome. Since the threshold is several centimeters high, it can not be considered as sleeper-free according to DIN EN 18040.

Another door arrangement is from the EP 2 107 199 B1 known. In this door assembly, the drive carrying the sash weight is located at the top of the frame. A load transfer thus takes place on an upper frame part, whereby on the bottom side a flat sleeper construction is made possible, which due to their low height (shallower than 20 millimeters) according to DIN EN 18040 can be considered as sleeper-free. The disadvantage here, however, is that the drive arranged above is not suitable for the removal of high wing loads, in particular wing loads above 100 kilograms.

The present invention is therefore based on the object, even at high wing loads to enable a sleek design of a door assembly.

This object is achieved with a door assembly having the features of claim 1. Thereafter, the door assembly is characterized in that the drive is sunk relative to the level of a frame adjacent to the bottom surface in a recess formed in the bottom surface and that the recess is at least partially closed by a cover. This allows a shallow threshold and thus a post DIN EN 18040 as a threshold-free or floor-level viewed passage are created, since the load is not carried out at or on the threshold, but underfloor through the arranged in the recess drive. For a structurally simple and reliable load transfer is realized in the ground floor surface. By the load transfer into the ground high wing weights, in particular wing weights of more than 100 kilograms can be removed. Through the cover, the recess is at least partially closed, in such a way that the door assembly can be easily passed by pedestrians as well as by wheelchair users. The on the side facing away from the wing side of the frame, serving to seal the door assembly threshold is formed without swelling or flush with the floor in the sense of DIN EN 18040, since the height is a maximum of 20 millimeters or less. Thus, high wing loads can be removed for sleeperless or flush design of the door assembly. Pedestrians and wheelchair users can thus pass through the door assembly due to their barrier-free design equally without difficulty.

The term "door arrangement" is to be understood here in the broadest sense, so that it can also be a window arrangement or the arrangement of a passage. The term "floor area" is to be understood here in the broadest sense, so that it does not necessarily have to be a floor, but, for example, can also act on a floor space.

The wing is coupled in a known manner by means of upper and lower Ausstellarmen to the frame. In this case, the wing can be brought into a closed, fitting to the frame and the door assembly sealing position. The wing is then arranged parallel to the frame and rests against the frame. The upper and lower Ausstellarme, which can also be referred to as Ausstellscheren are in the closed position. The wing can also be displaced relative to the frame in a tilted position, for which purpose only the upper Ausstellarme be spent in an open or extended position, so that the upper wing spar is removed from the frame. The lower Ausstellarme are then in the closed position. On the drive a pivoting process takes place, for example. Between carriage and running rail, which allows tilting of the wing. In addition, the wing can be moved to a parallel to the frame parked position, for which purpose the upper and lower Ausstellarme be spent in an open or extended position. In this position, a displacement of the wing relative to the frame is possible, along a direction of displacement. For structural design of the opening arms is here on the EP 2 107 199 B1 reference is made to the content of which reference is expressly made.

Advantageously, the cover may form part of the floor surface. Hereby, the design effort in the depression is kept low because the cover itself, but not any flooring, forms a portion of the bottom surface. Thus, any maintenance of the drive is simplified because the cover is directly accessible and can be easily removed for maintenance of the drive.

In concrete terms, it is conceivable that the cover is oriented flush with the floor surface. This allows the cover together with the bottom surface form a flush surface. Thanks to the flush transition from the floor surface to the cover, accessibility is once again optimized. A transition between cover and floor surface is called considered flush if the dimensional separation in the direction of gravity is less than 3 mm, preferably less than 2 mm, more preferably less than 1 mm.

Conveniently, an underfloor body can be arranged in the depression, which defines together with the cover an underfloor space in which the drive is received. In this way, the drive is arranged in a stable manner in the recess of the bottom surface and protected from environmental influences, eg. Coming from the bottom surface, protected. It is conceivable that the underfloor body is designed as a profile body with an L-shaped cross-section. In other words, the underfloor body can be a gutter with an L-shaped cross-section. An embodiment of the underfloor body with a U-shaped cross section is also conceivable.

In an advantageous manner, the drive can have a running rail and at least one carriage guided on the running rail. Thus, a reliable guidance of the carriage is ensured on the running rail with simple structural means. The carriage may have one or more, in particular two, rollers, which serve as low-friction guidance as possible.

In an advantageous manner, the running rail can be fastened to the underfloor body. For example, the running rail can be glued, riveted, jammed or screwed to the underfloor body. In a particularly advantageous manner, the running rail is formed integrally with the underfloor body. Hereby, a particularly stable connection of the running rail is created on the underfloor body, at the same time the assembly cost is reduced, since a fixing of the running rail on the underfloor body eliminated. Thus, the running rail can be formed directly in the production of the underfloor body, the underfloor body can be made for example as an extruded profile.

To provide a tilting possibility with simple structural means of the carriage and the running rail for tilting the wing form a joint with an oriented in the longitudinal direction of the running rail pivot axis about which the wing is tilted. As previously indicated, the wing is attached by means of Ausstellarmen the frame. The Ausstellarme can be formed, for example, as Ausstellscheren. To tilt the wing relative to the frame starting from a closed position of the door assembly (wing is sealingly attached to the frame), the upper extension arms or Ausstellscheren shift an upper spar of the wing from the frame towards the interior of the door assembly. Carriage and track remain stationary to each other, the coupled with the wing carriage is only pivoted to the running rail. Thus, a tilt function is realized with simple constructive means. With respect to the track rail, it is advantageous if this has a - viewed in cross section in the rail longitudinal direction - rounded portion which is in contact with the carriage.

Specifically, the pivot axis may be formed by the contact line between carriage and running rail. This is positive in terms of friction properties, since there is no relative movement between these two components in the contact area. It is also conceivable that the running rail has a convexly rounded end portion, which is in contact with a concavely rounded portion of the carriage. Hereby is one created large contact area, so that a reliable pivoting occurs. The pivot axis may also be oriented in the longitudinal direction of the track with such rounded components and within the cross section of the track, for example. At the center of a convex radius portion of the track.

Concretely, the contact line may be defined by contact between a roller guiding the carriage on the running track of the carriage and the running rail. It is conceivable that the running rail has a convexly shaped end portion and the roller has a corresponding, concave shaped portion which is formed circumferentially on the roller. This creates a secure coupling of the impeller and thus the carriage as a whole on the running rail.

Advantageously, the drive can be coupled to the wing by means of a support element and by means of a bearing element. Thus, a stable coupling of the carriage is realized on the wing. The support member may be formed as Tragarmbolzen, which at one end pivotally coupled to the bearing element and the other end with drive, for example. Rotationally fixed, can be. A non-rotatable mounting of the support arm on the bearing element and a pivotable coupling of the support arm to the drive are also conceivable. The bearing element may be formed, for example, as a so-called corner bearing. With regard to the drive-side coupling of the Tragarmbolzens is conceivable that the Tragarmbolzen is not located there directly on the carriage, but by means of a stay arm attached to the carriage. Thus, the Tragarmbolzen and thus the wing can be displaced in total relative to the frame in parallel.

Concretely, it is advantageous if the support element is dimensioned in its length such that in the installed position, the cover between the drive and the bearing element can be arranged and tilting of the wing is possible. Hereby, a collision of the corner bearing with the cover or the bottom surface can be avoided. Compared with a known from the prior art arrangement of the drive at or near the threshold of the frame and thus above a bottom surface of the Tragarmbolzen compared with a conventional Tragarmbolzen extended, for example by an amount of 0 to 80 millimeters, preferably 10 to 70 millimeters, more preferably 30 to 50 millimeters, more preferably about 42 millimeters. The Tragarmbolzen may have an overall length of 100 to 120 millimeters, preferably 110 to 155 millimeters, more preferably 112 millimeters. For example, it is conceivable that the Tragarmbolzen has a total length of 112 millimeters, wherein the distance required effecting about 86 millimeters.

With regard to the cover is conceivable that this is designed as a cover plate. In this case, the cover can be designed as a profile body with an L-shaped cross-section, for example as an extruded profile. For a dimensionally stable design is created that can carry high loads. For a structurally simple embodiment of the cover is alternatively conceivable that this is designed as a planar cover. In order to enable a parallel parking of the wing, the cover may have, regardless of their design or profile cross-section inlet curves that allow the support elements or Tragarmbolzen passing the cover.

The invention will be explained in more detail below with reference to FIGS.

FIG. 1 shows a generally designated by the reference numeral 10 door assembly. The door assembly 10 has a stationary frame 12. On the frame 12 is a wing 14, which can be permanently installed or in a known manner, for example, rotatable and tiltable and / or displaceable.

Another wing 16 is tiltable relative to the frame 12 and parallel off and can be moved in the parallel parked position along a direction of displacement 18, where it is seen from the interior 20 forth, moved when moving in front of the wing 14. The wing 16 has two lateral wing spars 16a, 16b and an upper wing spar 19a and a lower wing spar 19b.

The wing 16 is connected to the stationary frame 12 via four extension arms, namely two upper Ausstellarmen 22, 24 and two lower Ausstellarmen 26, 28 (in Fig.1 each only indicated). The lower Ausstellarme 26, 28 are each mounted on a drive 30, 32. The drive 30, 32 has a running rail 34 and in each case a carriage 36. The carriage 36 are connected to a pull rod 38 and each have two rollers 40.

As in FIG. 2 Larger, the drive 32 is not guided next to or at a threshold 42, but recessed below an adjacent to the frame 12 bottom surface 44. Thus, in the interior 20 in a bottom surface 44, a recess 46 is formed, in which an underfloor body 48 is arranged. The underfloor body 48 defines, together with the cover 50, an underfloor space 52 in which the drive 32 is accommodated. The cover 50 partially closes the depression 46 or the underfloor body 48. In this case, the cover 50 forms part of the bottom surface 44 and is arranged flush with the bottom surface 44.

The running rail 34 is formed integrally with the underfloor body 48. The underfloor body 48 can therefore also be referred to as a running rail profile 48. Of the Underfloor body 48 extends in the manner of a gutter along the displacement direction 18 (see Fig.1 and Figure 5 ). The displacement direction 18 is in Fig. 2 oriented orthogonal to the drawing plane.

The underfloor body 48 is an extruded profile. The underfloor body 48 has a substantially L-shaped cross section with a bottom surface 56 and a side leg 58. The side leg 58 may be up to the level of the bottom surface 44.

The cover 50 is designed as a cover plate. Specifically, the cover 50 has an L-shaped cross section with a first leg 62 and a second leg 64. The cover 50 also has inlet curves 68, which allow a parallel displacement of the wing 16 relative to the frame 12 when the cover 50 is mounted (see Figure 5 ). The cover 50 does not completely close the underfloor body 48, so that between the second leg 64 of the cover 50 and side legs 58 of the underfloor body 48, a gap 80 is formed which extends in the direction of displacement 18 or in the longitudinal direction of the running rail 34 (see Fig.1 and Figure 5 ).

As in FIG. 2 To recognize the drive 32 is coupled by means of a support member 70 and by means of a bearing member 72 with the wing 16. The support member 70 is formed as Tragarmbolzen 74 which is extended compared to a conventional Tragarmbolzen a mounted on or on the threshold drive. The bearing element 72 is designed as a so-called corner bearing 76 and attached to the wing 16. For the sake of simplicity, the support element 70 will hereinafter be referred to as Tragarmbolzen 74 and the bearing element 72 as a corner bearing 76th

The Tragarmbolzen 74 is pivotally mounted at one end in the corner bearing 76 and secured with its other end in an opening 78 in the lower extension arm 26.

If one of the upper Ausstellarme 22, 24, which can also be referred to as Ausstellscheren, from the in FIG. 6 enlarged illustrated closed position in an in FIG. 7 displaced shown open position, the wing 16 is first moved to a tilted position in which the carriage 36 and thus the entire wing 16 pivots relative to the running rail 34 (see Figure 3 ). The running rail 34 and the rollers 40 of the carriage 36 form a joint.

If the wing 16, starting from the in Fig. 3 shown tilted position moves in the direction of displacement 18, so open the lower extension arms 26, 28 and the Tragarmbolzen 74 is guided by the inlet curve 68 in the gap 80, so that the wing 16 is placed parallel to the frame 12 in parallel (see Figure 4 ). The wing 16 can be moved in the parallel parked position in the direction of displacement 18 parallel to the frame 12, wherein the Tragarmbolzen 74 are in the gap 80. A drive of the wing 16 relative to the frame 12 can be done manually or by motor. For example. For example, a manual drive may take place by displacing the sash by an operator. A motor drive can take place, for example, by a servomotor which, for example, can act on the upper extension arms 22, 24 or on the lower extension arms 26, 28.

The FIGS. 6 and 7 show an upper extension arm 22, which between a closed position (see FIG. 6 ) and an open position (see FIG. 7 ) can be relocated. The upper Ausstellarm 22 can also be used as Ausstellschere 22 are referred to and in the following also referred to as such.

The Ausstellschere 22 has a fitting carrier 82 and a relative to the fitting carrier 82 displaceable, guided at an angle 84 of the fitting carrier drive bolt 86. By driving the drive bolt 86, a control arm 88 from a bracket 82 substantially parallel alignment (see FIG. 6 ) and a relative to the bracket 82 angled position (see FIG. 7 ) are relocated.

The control arm 88 is pivotally attached to a pivot bearing 90. At the free end of the control arm 88 is a bolt member 92 with which the control arm 88 can be attached to the frame side.
