Description

[0001] The invention relates to a door arrangement comprising a longitudinally extending floor profile with a bottom surface, wherein the bottom surface is configured as a contact surface for placing the floor profile against a flat and preferably horizontally extended floor surface not belonging to the door arrangement, a pivotably and / or slidably held door leaf and a floor threshold also extending longitudinally, wherein the floor threshold provides a surface inclined relative to the bottom surface as a leveling element and the top surface of the floor profile opposite the bottom surface is placed against it.

[0002] From DE 20 2016 103 098 U1, a generic door arrangement is known in which a longitudinally sliding door is provided as an insect screen element. The sliding door is mounted laterally to the threshold on an end face facing away from the door leaf.

[0003] The object of the present invention is to further develop a door arrangement of the generic type.

[0004] To solve the problem, the invention in conjunction with the preamble of claim 1 is characterized in that a pleated element is provided as an insect screen and a guide groove extending in the longitudinal direction is formed in the inclined surface of the threshold, wherein the guide groove is designed as a pleated guide and the pleated element is arranged to be longitudinally displaceable in the guide groove.

[0005] The particular advantage of the invention lies in the fact that providing the guide groove in the inclined surface of the threshold allows for a compact design of the door assembly. The pleated insect screen element is guided in the guide groove. Therefore, a lateral attachment of the insect screen element is unnecessary. At the same time, the guide groove is integrated into the inclined surface of the threshold, i.e., recessed into it. When the pleated insect screen element is pushed to the side and the door leaf is in the open position, the passage is unobstructed. A tripping hazard that a guide groove mounted on the inclined surface would create is thus avoided. Furthermore, the open door assembly can be passed through barrier-free with a wheelchair, a walker, or a similar mobility aid.

[0006] According to a preferred embodiment of the invention, the guide groove has a U-shaped cross-section. It has a groove base that is parallel to the underside of the base profile. By orienting the groove base parallel to the underside of the base profile, a horizontal extension of the groove base is achieved for the typical application where the door assembly is mounted on a horizontally extended floor surface. The pleated element can be moved easily and with minimal force due to the horizontal orientation of the groove base. At the same time, the horizontal orientation of the groove base counteracts unintentional, independent movement of the pleated element within the guide groove by means of an inclination of the groove base towards an opening or closing position.

[0007] Another embodiment of the invention provides that the guide groove has drainage holes. These are preferably located in the area of ​​the groove base. Advantageously, the provision of drainage holes allows moisture, and in particular rainwater, to escape from the guide groove. The door assembly is therefore particularly suitable for outdoor use, and no special structural or planning measures are required to protect the door assembly from moisture or rain.

[0008] According to another embodiment of the invention, the threshold is designed as a thin-walled profile body comprising a load-bearing section with the inclined surface and the guide groove on one side, and a plurality of support struts on the other. The support struts are integrally formed with the load-bearing section and project from it in the direction of the floor profile. The threshold with the support struts is thus positioned against the floor profile. One support strut is preferably designed as a groove support strut and is provided in the area of ​​the guide groove. Particularly preferably, the groove support strut is integrally formed at the bottom of the guide groove. Alternatively or additionally to the aforementioned preferred embodiment of this development, it is possible for the load-bearing section to be positioned against the floor profile with a groove area forming the guide groove.Accordingly, no additional support strut is required for force-transmitting the threshold against the top of the floor profile. This simplifies manufacturing and thus reduces costs. The threshold also benefits from high stability and strength due to the groove support strut in the area of ​​the guide groove and / or the aforementioned groove area. This facilitates the insertion, support, and movement of the pleated element within the guide groove.

[0009] A further embodiment of the invention provides that the threshold with the guide groove is manufactured in one piece, in particular as an extruded profile. Advantageously, the one-piece threshold can be manufactured very cost-effectively. At the same time, assembly is simplified. Positioning the guide groove relative to or on the inclined surface is unnecessary.

[0010] According to another embodiment of the invention, the distance between the guide groove and the door leaf is greater than the distance to an end face of the threshold facing away from the door leaf. The guide groove is thus positioned off-center on the inclined surface of the threshold and shifted towards the end face. Advantageously, this provides sufficient clearance for fittings and handles on the door leaf, despite the compact design of the door assembly. Furthermore, if the door leaf is designed as a sliding door, it can be moved longitudinally and thus opened and closed independently of the position of the pleated element in the guide groove. The sliding door leaf and the pleated element can therefore be operated independently of each other.

[0011] Furthermore, a further advantageous embodiment of the door arrangement according to the invention provides that the floor profile and the threshold have corresponding positive locking elements for a positive connection between the threshold and the floor profile. Preferably, the positive locking element on the floor profile side is formed from the floor profile and / or the corresponding positive locking element on the threshold side is formed from the threshold. Particularly preferably, the positive locking element on the floor profile side is designed as a positive locking groove and the positive locking element on the threshold side as a positive locking lug. In this way, the door arrangement according to the invention can be implemented in a very simple manner from a design and manufacturing perspective. This applies particularly to the preferred embodiment and especially to the particularly preferred embodiment of this embodiment.

[0012] Further advantages, features, and details of the door arrangement according to the invention can be found in the dependent claims, the drawings, and the following description. Features mentioned therein can be essential to the invention individually or in any combination. Thus, the disclosure relating to the individual aspects of the invention can always be referred back to each other.

[0013] The drawings serve only as examples to clarify the invention and are not intended to be restrictive. They show: Fig. 1 a perspective partial view of a first embodiment of a door arrangement according to the invention, Fig. 2 a partial cross-section through the door arrangement according Fig. 1, Fig. 3. A perspective view of an assembly situation for a threshold of the door arrangement according to the Fig. 1 and Fig. 2, Fig. 4 a side view of the threshold Fig. 3, Fig. 5 a perspective partial view of a second embodiment of a door arrangement according to the invention, Fig. 6 a partial cross-section through the door arrangement according Fig. 5, Fig. 7 A perspective view of an assembly situation for a threshold of the door arrangement according to the Fig. 5 and Fig. 6 and Fig. 8 a side view of the threshold Fig. 7

[0014] A door arrangement according to the invention comprises in a door arrangement in the Fig. In the first embodiment illustrated in Figures 1 to 4, the essential components are a floor profile 20, a door leaf 10, a threshold 30 attached to the floor profile 20, and a pleated element 40 for insect protection. In this embodiment, the door leaf 10 of the door assembly is designed as a sliding door leaf that can be moved longitudinally in a longitudinal direction 1 of the door assembly. It comprises a door frame 11 and a roller 12 arranged in the door frame 11. The sliding door leaf 10 can be supported on the floor profile 20 by the roller 12 and moved relative to it in the longitudinal direction 1.

[0015] The floor profile 20 comprises a receiving section 21, which supports the sliding door leaf 10, a core 22 encompassed by the receiving section 21, and a connecting section 23 laterally attached to the receiving section 21. The receiving section 21 and the connecting section 23 provide a bottom surface 25 of the floor profile 20, with which the floor profile 20, or the door assembly as a whole, is placed against a flat, preferably horizontally extended, floor contact surface 2.

[0016] Furthermore, the base profile 20 in the present embodiment is designed in multiple parts. Besides the core 22, which is preferably made of a metallic material, in particular aluminum, it comprises a plastic body and a further metal body. The plastic body forms the receiving section 21 and part of the connection section 23. The further metal body is attached to and / or snapped into the plastic body, thereby completing the connection section 23. The connection section 23 thus consists partly of plastic and partly of metal. Both the plastic body and the further metal body are designed as thin-walled profiles and, in particular, as extruded profiles with a constant cross-section.

[0017] The connecting section 23 provides an upper surface 24 of the base profile 20 that is inclined relative to the lower surface 25. The inclination of the upper surface 24 is such that the connecting section 23 tapers towards an end face 26 of the base profile 20 opposite the receiving section 21. Therefore, with the lower surface 25 oriented horizontally, the upper surface 24 slopes towards the end face 26 and away from the receiving section 21. The upper surface 24 thus allows moisture to drain away towards the end face 26. The inclination of the upper surface 24 to the lower surface 25 can, for example, be 3°.

[0018] The threshold 30 is also designed as a thin-walled profile body. Preferably, the threshold 30 is made of a metallic material, in particular aluminum. It is located above the connection section 23, laterally next to the receiving section 21, and below the door leaf 10.

[0019] Furthermore, the threshold 30 comprises a load-bearing section 32, a fastening section 37 projecting from the end of the load-bearing section 32, and support struts 35, 36 projecting from the load-bearing section 32 towards the floor profile 20. The threshold 30 is pressed against the upper surface 34 of the floor profile 20 by means of the support struts 35, 36. Additionally, a contact area is formed between the fastening section 37 of the threshold 30 and the end face 26 of the floor profile 20, in which the fastening section 37 contacts the end face 26 of the connecting section 23. In this contact area, the floor profile 20 and the threshold 30 are detachably connected to each other by screws 3.

[0020] The support section 32 of the floor threshold 30 provides an inclined surface 31 on a side opposite the support struts 35, 36 of the floor threshold 30 and the upper surface 24 of the floor profile 20. A guide groove 33 extending in the longitudinal direction 1 is recessed in the inclined surface 31. The guide groove 33 serves as a pleat guide for the longitudinally displaceable arrangement of the pleated element 40.

[0021] In the present embodiment, the threshold 30 is attached to the upper surface 24 of the floor profile 20 as a leveling element of the door assembly, such that a height difference of approximately 2.5% is achieved between the level of a door opening and a floor covering connected to the threshold 30, for example, a patio slab. The leveling element 30 thus ensures that moisture, and in particular rainwater, is directed away from the door assembly towards the floor covering.

[0022] The guide groove 33 for the pleated element 40 is integrated into the inclined surface 31 of the threshold 30 in such a way that it is recessed relative to the surface 31. It therefore does not create a tripping hazard and can be crossed or driven over without obstruction. In cross-section, the guide groove 33 is U-shaped. Two parallel, opposing side surfaces of the guide groove 33 are connected by a groove base 34 of the guide groove 33, which is oriented parallel to the underside 25 of the floor profile 20. Due to its parallelism to the underside 25 of the floor profile 20, the groove base 34, when installed, has the orientation of the floor contact surface 2. In particular, the groove base 34 extends horizontally, and the opposing side surfaces enclosing the groove base 34 extend vertically.

[0023] Drainage holes (not shown) may be provided in the groove base 34. These drainage holes allow moisture to escape from the guide groove in the desired manner. The moisture can then be channeled away along the top surface 24 of the base profile 20, which is also inclined towards the end face 26.

[0024] The threshold 30 achieves a high degree of strength through the support struts 35, 36. In the present embodiment of the invention, one support strut 36 is designed as a groove support strut 36 and is integrally formed with the groove base 34 of the guide groove 33. The groove support strut 36 provides the threshold 30 with additional stability in the area of ​​the guide groove 33. This makes it possible to support the pleated element 40 on the threshold 30 in the area of ​​the guide groove 33 without deformation or damage. At the same time, the groove support strut 36 provides stabilization when the pleated element 40 is actuated.

[0025] In the Fig. Figures 5 to 8 show a second embodiment of the door arrangement according to the invention, with the individual illustrations depicting the Fig. 1 to 4 of the first embodiment. Identical or equivalent components are designated with the same reference numerals, wherein the Fig. 5 to 8, compared to the Fig. 1 to 4, for the sake of clarity, have been reduced in their reference symbols. The references in the Fig. However, the 5 to 8 missing reference symbols become immediately apparent from a comparison with the Fig. 1 to 4. Furthermore, the second embodiment will only be explained below to the extent of its distinguishing features. Otherwise, reference can be made to the above explanations of the first embodiment.

[0026] In addition to the support struts 35, 36, wherein the support strut 36, designed as a groove support strut, is not arranged centrally relative to the guide groove 33, but rather on a side of the guide groove 33 facing away from the door frame 11, the load-bearing section 32 of the threshold 30 is attached to the floor profile 20 with a groove area forming the guide groove 33. See in particular the Fig. Figure 8, in which the upper surface 24 of the base profile 20 is symbolized by a dashed line. The aforementioned groove area thus serves itself to support the floor threshold 30 against the base profile 20, so that an additional support strut is unnecessary in this respect. Furthermore, in the second embodiment, compared to the first embodiment, the load in the area of ​​the guide groove 33 is distributed on the one hand to the aforementioned groove area and on the other hand to the groove support strut 36, so that this load does not have to be absorbed and transferred solely by means of the support strut 36.

[0027] Analogous to the first embodiment, the base profile 20 and the threshold 30 have corresponding positive locking elements for the purpose of a positive connection of the threshold 30 to the base profile 20, wherein the positive locking element on the base profile side is formed from the base profile 20 and the corresponding positive locking element on the threshold side is formed from the threshold 30, namely such that the positive locking element on the base profile side is designed as a positive locking groove 27 and the positive locking element on the threshold side is designed as a positive locking lug 38. As can be seen in particular from the Fig. 2 and Fig. As can be seen from Figures 4, 6, and 8, the respective positive locking lug 38 is combined with one of the two support struts 35 in both embodiments. For the sake of clarity, the two positive locking elements 27, 38 are shown only in the Fig. 6 and Fig. 8 is designated; however, the results in the Fig. 2 and Fig. 4 missing references 27, 38 directly from a combination of the Fig. 2 and Fig. 4 with the Fig. 6 and Fig.8. Of course, embodiments of the invention are also conceivable in which the corresponding positive locking elements are designed in a different way. In contrast to the first embodiment, in which the threshold 30 is screwed to the end face 26 of the floor profile 20 by means of the fastening section 37 as described above, the threshold 30, according to the second embodiment, rests only against the upper surface 24 of the floor profile 20, with the threshold 30 being positively connected to the floor profile 20 solely by means of the aforementioned corresponding positive locking elements 27, 38. However, embodiments are also conceivable in which such a threshold is connected to the floor profile by means of further fastening techniques in addition to the aforementioned positive locking.Furthermore, the corresponding positive locking elements can be designed in such a way that these positive locking elements not only enable a positive locking, but also a frictional locking, i.e. a clamping locking, and / or a latching locking.

[0028] As can be seen from the two exemplary embodiments, providing the guide groove 33 in the inclined surface 31 of the threshold 30 enables a compact design of the door assembly. The pleated insect screen element 40 is guided in the guide groove 33. Therefore, a separate insect screen element cannot be attached to the side. At the same time, the guide groove 33 is integrated into the inclined surface 31 of the threshold 30, i.e., recessed into it. When the pleated insect screen element 40 is pushed to the side and the door leaf 10 is in an open position (not shown), the passage is clear. A tripping hazard that a guide groove 33 mounted on the inclined surface 31 would create is thus avoided. Furthermore, when the door leaf 10 is in its open position, the door assembly can be traversed barrier-free with a wheelchair, a walker, or a similar walking aid (not shown).

[0029] However, the invention is not limited to the two exemplary embodiments described. Accordingly, the door arrangement according to the invention can be adapted to the specific local conditions, depending on the requirements of each individual case. The door arrangement according to the invention can therefore be used advantageously in a multitude of different applications.
