Description

The invention relates to a door assembly having a door frame, a door leaf and at least one door hinge, which has a frame part and at least one rotatably received on the frame part articulated arm and with which the door is pivotally mounted on the at least one articulated arm on the door frame, wherein the door frame in a closed position of the door leaf has a parallel to the door aligned mirror portion and a perpendicular thereto, laterally adjacent to the door soffit and wherein the door hinge is inserted with the frame part in an opening of the soffit and behind the mirror portion is at least partially hidden, wherein the mirror portion on the height of the frame part has an emanating from the soffit lateral recess, in which the articulated arm pivots in a movement between the closed position and a maximum open position of the door leaf.

From practice different band constructions are known for different purposes. The present invention relates specifically to a door assembly in the form of a house or room door. The door hinge must be able to absorb the weight and leverage exerted by the door leaf. A corresponding door usually has an area of at least 1 m ² and a weight of 10 kg.

Against this background, the door hinge on the one hand must have sufficient stability, on the other hand often an inconspicuous appearance of the door hinge is required so that the door formed from a door, a door frame and usually at least two door hinges well integrated into a surrounding wall surface and has a high-quality appearance ,

The invention relates to door assemblies with hinges, which are arranged at least partially hidden, wherein the frame part is inserted laterally into the reveal of the door frame. A door assembly with the features described above is known from EP 2 476 837 A1 known. The door leaf is folded, wherein a Türbandseitiger door rebate rests in the closed position on the mirror portion and also conceals the recess formed in the mirror portion. This results in the disadvantage that the folded door arrangement projects beyond the mirror section in the closed position.

Another door arrangement is from the DE 101 64 979 B4 known. The door hinge is used as Hidden door hinge in the narrow side of a door leaf and the reveal of a door frame and not visible in a closed state of the door. The two hinge brackets are rotatably guided at one of their ends about a vertical axis of rotation and at its other end longitudinally displaceable and rotatable. Furthermore, the two hinge brackets at the ends connecting central portions are connected to each other about a further vertical axis of rotation. This results in a 5-axis joint arrangement, in which two of the joint axes are additionally guided along scenes.

The door hinge is characterized by a stable construction and good handling characteristics. Thus, the scenes can be formed on the wing part and on the frame part, they must have a sufficient size, with the door frame and on the door and a sufficient receiving frame must be available.

From the DE 10 2015 120 549 B3 If a door arrangement is known in which, starting from the closed position, the opening angle is up to a maximum open position at 180 °. The door hinge has only a single articulated arm, which is rigid on the door frame and about a pivot axis on the Door leaf is rotatably mounted. By a pronounced U-shape of the articulated arm, the door can be swung open. A concealed arrangement of the door hinge is only possible with comparatively thick doors.

From the DE 20 2008 004 509 U1 It is known to cover screw holes of a hinge part by a panel, which can be arranged substantially over the entire surface, in particular glued. Starting from the generic prior art, the present invention seeks to provide a particularly compact and high quality door assembly. In particular, it should be possible to integrate the frame part with a small footprint in the door frame and to use a door glass.

The object of the invention and solution of the problem is a door assembly according to claim 1.

According to the invention, a larger clearance for the movement of the at least one articulated arm is provided by the recess. The articulated arm can be easily pivoted beyond a position in which the articulated arm would abut laterally without the recess at the mirror portion. Although in the context of the invention, a hidden arrangement of the frame part of the door hinge is provided in an opening of the soffit and behind the mirror portion, starting from the soffit a recess in the mirror portion is accepted, which is also exposed in a closed door, or preferably covered by a separate screen.

In the context of the invention, therefore, an area is used for the movement, which was previously not available. It is thus possible for a person skilled in the art to achieve a more compact construction, to achieve larger opening angles or the rest of the construction of the door hinge, such as the positioning of at least one pivot axis to vary freely.

Starting from the soffit, the recess preferably has a depth of between 5 mm and 50 mm, in particular between 8 mm and 30 mm, in order on the one hand to provide a sufficient additional movement space and, on the other hand, to avoid excessive optical impairment or weakening of the mirror section.

The inventively provided aperture is to be designed in the invention so that on the one hand in the closed position of the door leaf, the recess is covered and on the other hand, the recess is released during the pivoting movement for pivoting the at least one articulated arm.

Thus, it is conceivable that the diaphragm is movable, in particular pivotally mounted on the door frame. For example, the diaphragm may be rotatably mounted on the edge of the recess along a vertical axis and urged by a spring or the like. During an opening movement, such a panel can then be pressed in front of the at least one articulated arm when it dips into the recess initially covered by the panel.

Alternatively, the panel can also be fastened in a suitable manner to the at least one articulated arm or preferably to a wing part of the door hinge. In the context of such an embodiment then the frame part and the wing part of the door hinge are connected by the at least one articulated arm, wherein the wing part is connected to the door leaf. The wing part can be used for example laterally in the narrow side of a door or hold a glass door leaf clamped.

If the panel is fastened to the at least one articulated arm or preferably to the wing part, certain compensating movements may be necessary during a closing movement of the door leaf, in order to avoid jamming or scratching of the panel.

In addition or as an alternative to a movable arrangement of the panel on the wing part, the recess may also be partially filled by a cover bracket arranged on the frame part of the door hinge, which is movable to a certain extent. Such a cover bracket can then serve for the previously described aperture as a guide and support surface. In particular, it is provided in the context of such a configuration that the diaphragm is in the closed position with a part of its edge over the Abdeckbügel.

As already explained above, a large opening angle is made possible by the recess in a compact design even with doors with a door rebate. Accordingly, it is provided according to a preferred embodiment of the invention that, starting from the closed position of the opening angle to reach the maximum open position between 135 ° and 185 °, in particular between 170 ° and 180 °.

According to the invention, the recess is provided to provide for the at least one articulated arm a greater freedom in the movement. Usually, it is provided that the at least one articulated arm is pivoted in the maximum open position in the recess.

In order to further improve the kinematics of the door hinge, the at least one articulated arm can have a C- or U-shape in a plan view with a viewing direction parallel to the pivot axis between the articulated arm and the frame part.

In the context of the invention, it is possible that the door hinge has only a single articulated arm. In addition, however, the invention also extends to joint structures with two articulated arms, such as in their basic structure of the DE 101 64 979 B4 are known.

Two articulated arms connecting the frame part with a wing part can be rotatably supported and guided in a wide variety of ways. According to the DE 101 64 979 B4 the two articulated arm are each rotatable on one side and longitudinally displaceable on the other side and rotatably guided and beyond also also connected to each other. Reference will now be made, by way of example, to an alternative embodiment likewise encompassed by the invention, in which two articulated arms are respectively received in a rotatable manner at their two ends and are not connected to one another.

Regardless of the particular kinematics provided in a door hinge with a first articulated arm and a second articulated arm is preferably provided that both articulated arms engage in the recess at the maximum opening position.

Usually, the door is attached at least with two hinges on the door frame, the door hinges can be made the same. The following explanations therefore relate by way of example to the arrangement of one of a plurality of door hinges on the door arrangement.

In the closed position of the door hinge, the door frame has a mirror section aligned parallel to the door leaf and a soffit adjoining the door leaf laterally, the soffit starting from the mirror section having a first reveal section and a second reveal section adjoining thereto via an inwardly directed step can have.

Thus, the mirror portion extends along a first horizontal direction as well as the vertical direction, while the reveal extends along the second horizontal direction and the vertical direction except for the optionally provided offset along the first horizontal direction at the step. The step preferably forms a stop for the door leaf, whereby a conventional door seal can also be arranged on the step.

The frame part is inserted into the opening of the reveal, so that the frame part is arranged concealed in the direction of the mirror portion. In particular, in the presence of a step, the opening may extend from the first reveal section to the second reveal section, so that then the area of the step can also be used for the arrangement of the frame part. As stated above, the door assembly may in particular comprise a glass door leaf, although other materials may also be considered. According to a preferred embodiment of the invention it is provided that the door is unfolded and particularly preferably has a simple plate shape.

The edges of the door leaf are then usually completely surrounded by the soffit and are thus completely within or next to the mirror portion.

In the closed position, the door can, for example, connect flat to the mirror section or even jump back relative to the mirror section. The door wing can be integrated so particularly inconspicuous and harmonious in a wall design.

According to a preferred development, it can also be provided that a separate cover part is arranged on the frame part, which has a step corresponding to the shape of the reveal, so that a first Cover portion of the cover at least substantially flush with the first reveal portion and a second cover at least substantially flush with the second reveal portion.

In order to allow an adaptation to different frame shapes, different cover parts and / or adjustable cover parts can optionally be provided.

The Fig. 1 shows a section of a door assembly, such as a house or room door with a door frame 1, a door 2 and a door hinge 3. The door 2 is usually about at least two of in Fig. 1 Door hinges 3 supported on the door frame 1, wherein the Fig. 1 one of the two identically formed door hinges 3 shows.

Already from the Fig. 1 and in particular the horizontal sections according to the FIGS. 3 to 5 It can be seen that the door hinge 3 in the illustrated embodiment has a 4-axis hinge assembly. Concretely, the door hinge 3 has a first articulated arm 4, which is arranged in a vertical direction Z between a second articulated arm 5 and a third articulated arm 6.

The second articulated arm 5 and the third articulated arm 6 are of the same design and also rotatably connected to a frame part 7 and a wing part 8 of the door hinge 3 in the same way. With regard to the movement of the door hinge 3 so the second articulated arm 5 and the third articulated arm 6 behave the same way. The symmetrical with respect to a median plane arrangement of the second articulated arm 5 and the third articulated arm 6 is provided for the sake of a uniform force distribution and purely exemplary.

In any case, the joint construction shown is purely exemplary. Basically, in the context of the invention, only a single articulated arm similar to that in the DE 10 2015 120 549 B3 be provided. In a joint arrangement with two articulated arms, for example, embodiments according to the DE 101 64 979 B4 into consideration. In addition, scissor-type joint structures with five pivot axes are known, which may also be provided within the scope of the invention.

For the sake of simplicity, however, reference will be made below, by way of example only, to the 4-axis articulated arrangement shown in the figures, the advantages described being the same for the other articulated structures.

Already from the Fig. 1 it can be seen that the door hinge 3, starting from a closed position has an opening angle of 180 ° until reaching a maximum open position.

For a better understanding of the construction of the door hinge this is in the Fig. 2 shown without the door frame 1 and the door 2.

The exact arrangement of the first articulated arm 4 and the second articulated arm 5 and the kinematics of the door hinge 3 in an opening movement are from the Fig. 3 to 5 seen.

Accordingly, in the 4-axis joint arrangement, the first articulated arm 4 is rotatably mounted on the frame part 7 rotatably about a first frame part axis 9a and on the wing part 8 rotatably about a first wing part axis 10a.

The second articulated arm 5 is fixed in a comparable manner on the frame part 7 rotatably about a second Zargenteilachse 9b and on the wing part 8 rotatable about a second wing part axis 10b. It can also be seen from the figures that all articulated arms 4, 5, 6 are not directly connected to each other. A connection takes place only via the support of the articulated arms 4, 5, 6 on the Zargenteilachsen 9a, 9b and the Flügelteilachsen 10a, 10b.

The Zargenteilachsen 9a, 9b and the wing part axes 10a, 10b are arranged so that the door can be pivoted by 180 °. This will be in Respect to the Fig. 3 to 5 achieved in that during an opening movement from the closed position to the open position, the articulated arms 4, 5, 6 relative to the frame part 7 in a first direction of rotation and the wing part 8 relative to the articulated arms 4, 5, 6 also rotate in the first direction. In the Fig. 3 to 5 the articulated arms 4, 5, 6 rotate counterclockwise with respect to the frame part 7. Furthermore, the wing part 8 also rotates counterclockwise relative to the articulated arms 4, 5, 6, so that ultimately the angles of rotation add up to the opening angle to be achieved.

In the Fig. 3 to 5 It can also be seen that the articulated arms 4, 5, 6 have a pronounced U-shape. According to the Fig. 5 allows the U-shape that the articulated arms 4, 5, 6 can be pivoted about a mirror portion 11 of the door frame 1 around. In order to simultaneously limit the installation depth of the frame part 7 in a first horizontal direction X and a second horizontal direction Y, the mirror portion 11 is provided starting from a reveal 12 of the door frame 1 according to the invention with a recess 13, which will be explained further below.

In order to characterize the shape of the U-shape, the distance a ₁ between the first frame part axis 9a and the second wing part axis 10a can be compared with a depth of the U-shape for the first hinge bracket. The depth of the U-shape can be determined by determining the maximum distance a ₂ to a middle section of the first articulated arm 4 perpendicular to a connecting line between the first frame part axis 9a and the first wing part axis 10a. The ratio of the distances a ₂ : a ₁ is preferably at least 0.5.

In the same way for the second articulated arm 5 between the second Ziggenteilachse 9b and the second wing part axis 10b, a distance b ₁ and perpendicular to a distance b _{2 are} determined, whereby also here the ratio b ₂ : b _{1 is} preferably greater than 0.5.

In order to stabilize the door hinge 3 and to keep tension forces away from the frame part axles 9a, 9b and the wing part axles 10a, 10b, at least one of the articulated arms 4, 5, 6 in the closed position and / or the open position on a stop face 14a, 14b of the frame part 7 and / or the wing part 8 abut.

In the concrete embodiment it is provided that in the maximum open position according to the Fig. 5 the first articulated arm 4 rests against a first stop surface 14a of the wing part 8, while in the closed position the second articulated arm 5 according to FIG Fig. 3 abuts against a second stop surface 14b of the wing part 8.

Due to the exemplified embodiment of the door hinge 3 with the 4-axis hinge arrangement, the wing part 8 can be made relatively small. Laterally of the door leaf 2 formed from glass, only the first wing part axis 10a and the second wing part axis 10b are arranged with an offset in the second horizontal direction Y.

In addition, the wing part 8 comprises a clamping arrangement 15, with which the door leaf 2 made of glass can be fixed in a particularly simple manner by means of clamping screws. When loosening the clamping screws clamping arrangement 15 of the door 2 is also adjustable in the vertical direction Z and also to a certain extent along the first horizontal direction X. Additionally or alternatively, an adjustment in at least one direction X, Y, Z may also be provided on the frame part 7.

According to the Fig. 3 For example, the first frame part axis 9a and the second frame part axis 9b are offset from each other along the first horizontal direction X.

The Fig. 6 shows a section of the also in Fig. 1 shown door in a closed state, with respect to the Fig. 1 other attachments are available.

First, it can be seen that the door frame 1 on the one hand has the previously mentioned mirror portion 11 and a along the second horizontal direction Y and the vertical direction Z extending reveal 12.

The reveal 12 is provided with a step 16, which separates a subsequent to the mirror portion 11 first reveal portion 17 of a second reveal portion 18.

In known manner, the step 16 forms a stop surface for the door leaf 2, wherein on the step 16 and a sealing groove for receiving a door seal, not shown, is provided.

Between the door 2 and the first reveal portion 17 remains above and below the door hinge 3, a lateral gap. In a comparison with the Fig. 1 It can be seen that the frame part 7 is inserted into an opening 20 which extends from the first reveal portion 17 into the second reveal portion 18 and thus beyond the step 16.

According to the Fig. 1 is the frame part 7 hidden within the opening 20 to the outside by the mirror portion 11 and also recessed against the soffit 12, wherein to adapt to the shape of the soffit 12th the frame part 7 is covered with a separate cover part 21, which is also adapted to the shape of the step 16.

The cover part 21 has a first cover section 21a, which is flush with the first reveal section 17, while a second cover section 21b is flush with the second reveal section 18.

In principle, an adaptation of the cover 21 to different frame geometries and in particular different height of the step 16 may be provided. In the simplest case, for example, for different heights of the stage 16 different cover parts 21 are kept available as an accessory. In addition, it is also possible for the cover part 21 to have a multi-piece design, in which case a front section is adjustable relative to a rear section. For example, screws, a multi-stage locking connection or an adjustable interference fit can be provided for the setting.

According to the Fig. 6 remains between the door 2 and the first reveal portion 17, a small lateral gap. However, since according to the Fig. 3 to 5 the wing part 8 extends partially laterally of the door leaf 2, the wing part 8 is located exactly in the region of the gap between the door 2 and the first reveal portion 17. In order to achieve a uniform, high-quality appearance against this background, a panel 22 is placed on the wing part 8, which also conceals the recess 13.

So that the panel 22 is arranged in a closed position of the door leaf 2 flat and preferably gap-free with respect to the mirror portion 11, the recess 13 formed in the mirror portion 11 is filled at its edge by a separate Abdeckbügel 23.

The aperture 22 and the Abdeckbügel 23 are in the Fig. 7 shown in the dissolved state. The Abdeckbügel 23 can be arranged with end-side pin 24 on the frame part 7, wherein preferably still a certain mobility relative to the wing part 8 is possible. If, for example, the wing part 8 is adjustable along the vertical direction Z, it can be ensured by a mobility of the cover bow 23 that it is always arranged tension-free in the recess 13.

In order to securely hold the cover bracket 23 in the recess 13, this has a holding web 25, which can engage behind the mirror portion 11. In addition, the cover bracket 23 forms a support surface for the panel 22. In a closed door, the aperture 22 overlaps the support surface of the support bracket 23, so that no continuous gap is visible and gives the impression of a high-quality, closed surface.
