Barrier-free threshold, especially for old buildings or renovations

Description

[0001] The invention relates to a barrier-free threshold, in particular a threshold for old buildings or renovations, which can be placed on a finished floor, wherein the threshold seals off an outside area of ​​a building from an inside area or two rooms from each other in cooperation with a window or a door.

[0002] A generic speed bump is known, for example, from the German patent application DE 10 2005 035 220 A1.

[0003] The application DE 10 2006 007 742 A1 also concerns a threshold for a door element for sealing the floor area between two rooms. DE 10 2005 030 462 A1 further concerns a threshold arranged in the floor area of ​​building openings (in particular exterior doors).

[0004] The utility model DE 20 2010 004 020 U1 further discloses a threshold for a building element, e.g. a window, a door or the like, which, in cooperation with a lower sash frame, seals the space between the threshold and the lower sash frame.

[0005] Such thresholds are well known. However, the problem with so-called renovation or old building thresholds is that, due to the fact that no changes to the floor are possible or unwilling to be made on site, such thresholds do not have a floor recess. Particularly when, as in the present invention, rooms are to be separated from one another in a barrier-free manner, or an interior from an exterior, it is necessary to make such thresholds very flat, since the regulations for nursing homes, hospitals, or generally for barrier-free spaces no longer permit elevations of up to 2 cm. Modern thresholds must therefore be flatter.The problem with such barrier-free floor thresholds is, on the one hand, to create a transition that allows wheelchairs, hospital beds, walkers or the like to roll over, but at the same time to ensure secure sealing and, above all, thermal protection in the area between the floor and the door or its lower edge.

[0006] A frequently encountered problem is that thermal separation, particularly of metal thresholds, is complicated. Due to the flat design of such thresholds, the current state of the art is unable to achieve thermal separation that meets the current requirements of building owners and architects. Furthermore, thresholds of the type in question are often made of light metal or metal, which naturally implies that these materials allow for very good heat transfer, which is precisely what is not desired. Consequently, at least some thermal separation must be present in such a threshold. This is usually achieved by inserting a material that is a poor heat conductor into the threshold.A further problem is that, in the direction of installation of the threshold, if it is made of light metal or metal, heat also passes from top to bottom into the floor, so to speak, which is why thermal insulation is also necessary here. Current thresholds do not meet current requirements regarding thermal insulation, and especially regarding heat transfer behavior.

[0007] Particularly when magnetic seals form at least part of the sealing arrangement of the door or window, a further problem exists in the state of the art: the water that may enter the grooves in the threshold or its base body must be drained away. Due to the very flat design and construction of the barrier-free threshold, it has not yet been possible to develop a corresponding drainage concept in the state of the art that ensures an even flatter design than previously common.

[0008] Based on this, it is the object of the invention to eliminate at least one of the previously described disadvantages of the prior art.

[0009] The invention is based on the previously described prior art and proposes to solve the stated problem a barrier-free threshold according to the independent patent claims 1 and 2, in particular an old building or renovation threshold, which can be placed on a finished floor without a floor recess, wherein the threshold seals off an outside area of ​​a building from an inside area or two rooms from each other in cooperation with a window or a door, consisting of a base body which has two grooves for receiving magnetic sealing strips, wherein the two magnetic sealing strips, viewed from outside to inside, are arranged next to each other in the base body,wherein a first thermal separation is provided on the inward-facing side of the base body and a second thermal separation is provided on the outward-facing side of the base body, and wherein a lower closure element is arranged on the side of the base body facing the floor to define a drainage channel connecting the grooves to an outlet provided on the outside of the base body.

[0010] According to the invention, it is provided that at least on one of the sides of the threshold a corresponding leg with a predetermined bending point is provided in order to bring this leg to the level of the respective floor, or it is provided that a leg and / or a connecting profile is connected to the threshold with a pivoting device in order to bring this leg and / or the connecting profile to the level of the respective floor.

[0011] The solution according to the invention achieves a drainage concept for incoming moisture or dripping water, which is not yet available in the prior art, even for barrier-free thresholds such as Altbauschwelle. Any water that enters is directed outwards from both grooves through a drainage channel that has corresponding outlet openings on the outward-facing side. This makes it possible to keep the interior area free of moisture even if small amounts of water should enter the grooves of the magnetic sealing strips due to heavy driving rain or rain associated with storms. Any condensation that may arise, for example caused by large temperature differences, can also be drained away accordingly via the drainage channel according to the invention.

[0012] It is also possible to design the lower end element in such a way that, in addition to its dissipation function, it also improves thermal insulation by reducing heat transfer. In an embodiment to be described later, it is possible to manufacture the lower end element from a material that conducts heat poorly. A clever variant, however, also allows for a light metal design, for example, by significantly reducing the overall contact surface of the lower end element and the threshold. This, of course, also enables lower heat transfer due to the smaller surface area, which in its simplest form already leads to an improvement in thermal insulation properties.

[0013] According to the invention, the drainage channel is connected to the groove or to both grooves in such a way that escaping water is directed directly into the outlet or into a drainage channel, respectively. The outlet or its outlet openings are arranged offset relative to the inner webs in the base body. The offset arrangement of the webs is an extremely advantageous variant because it prevents any strong wind forces impacting the threshold from penetrating directly into the drainage channel, but rather significantly reduces the effect or flow of the wind, allowing water to still flow unhindered even in strong winds.

[0014] It was further found that it is advantageous if an outward-facing extension is provided on the lower end element, which forms a support or connection for a door frame or French window frame, at least in the edge area. When exterior doors or balcony elements are designed as French windows, it is common for a frame, which forms the frame of the door or window, to be arranged outwardly in the masonry area. The corresponding opening and closing elements are also arranged on this frame, i.e., corresponding hinges and / or locking or locking devices are located there.To ensure a proper connection with the threshold, a corresponding extension is provided on the lower connecting element, at least on the outward-facing side, so that a corresponding transition is also present in the floor or floor area. Cleverly, the extension also serves as a support or connection for the frame.

[0015] In one variant of the invention, struts pointing toward the floor are provided, particularly in the area of ​​the extension, to support the support of the threshold or the base body and / or the extension. These struts are spaced at such a distance that sagging does not occur even when the threshold or extension is loaded. However, the struts simultaneously serve to improve thermal insulation by significantly reducing the overall support surface for the threshold technology.

[0016] In the prior art, it was common practice to install thresholds as old-style thresholds, meaning they were fully installed on the ground. A light metal or metal construction naturally provides excellent heat transfer, so thermal insulation in the lower area was not ideal.

[0017] The inventive design now ensures that reduced heat transfer is achieved simply by reducing the support surface in the area of ​​the extension up to the thermal separation of the threshold. It is also advantageous if either the struts and / or the entire extension are made of a material that conducts heat poorly. However, since this involves considerable manufacturing effort, the design in the form of an extension, whose support is provided by the corresponding struts of the same material, is very advantageous.

[0018] The base body of the threshold has corresponding receiving grooves on the inward-facing side for connecting to the thermal break, so that the thermal break, which is naturally made of a material with poor thermal conductivity, can be connected between the inner part of the base body and the outward-facing part of the base body or with the extension. The base body, in the inward-facing area, is positioned at the same height as the struts of the extension or the lower end elements. This ensures even support for the threshold and the extension. The thermal insulation effects of this design have already been described.

[0019] It is also advantageous to provide an adapter for attaching the frame to the threshold. This adapter can, of course, be adapted to the respective dimensions depending on the respective design of the threshold and / or frame. The adapter serves both to attach the frame to the threshold and to attach the frame to the threshold. It forms the connection between the threshold and the frame.

[0020] As already mentioned, an outward-facing leg is provided on the base body of the threshold, beneath which the outlet or a plurality of outlet openings is / are located. The effects of this design have already been described. In particular, the outlet is directly connected to the drainage channel, allowing the water to be drained directly from the grooves for the magnetic sealing strips to the outside. It is advantageous if the drainage channel has a slight slope.

[0021] A clever development of the previously described variant provides for a second thermal break on the outward-facing side of the base body. This clever design naturally further impairs the thermal insulation, or rather, the heat transfer through the threshold, while improving the thermal insulation.

[0022] The barrier-free threshold according to the invention therefore simultaneously solves a number of problems encountered in the prior art, namely, on the one hand, the improvement of the thermal separation and thus the insulating properties of a door or window element as a whole, and, on the other hand, the problem of drainage. At the same time, care is taken to ensure that the barrier-free threshold continues to comply with accessibility regulations, i.e., that the construction height remains below the permissible height for such barrier-free transitions. The threshold is designed to be very flat and, particularly in the areas where the threshold rises from the floor and where it falls back down to the floor, is very flat with a small radius or a slight curve. This also applies to barrier-free transitions in countries where the overall requirements for thermal insulation are not yet so high.

[0023] Such door or window elements for such transitions are characterized by the fact that their installation depth does not correspond to German or European standards, but rather their strength or thickness is considerably thinner. This naturally requires a barrier-free threshold to be designed to match the threshold for old buildings or renovations. The problem with such thresholds is arranging two magnetic seals, or the corresponding grooves for them, next to each other in such a way that they work absolutely reliably even with a shallow door installation depth. In particular, they ensure that the magnetic strips are attracted differently in a version with two magnetic strips, so that only the strip above which the corresponding counter magnet is located is attracted.This problem is also solved by the invention, whereby the transitions are also designed with corresponding curves so that one can easily roll over them with a wheelchair, a hospital bed or a walker or other related aids.

[0024] Even with a threshold that is not as wide, drainage of the two grooves for the magnetic strips is ensured. For this purpose, a drainage channel is provided between the side of the base body facing the floor and a lower end element. This makes it possible, particularly thanks to the clever connection of the two grooves with the drainage channel, to provide drainage to the outside, even in a very flat, barrier-free threshold according to the invention. A further problem that is solved by the invention has already been mentioned, namely that the heat transfer from top to bottom or from bottom to top from the floor to the room is also interrupted, namely that the lower end element of the threshold is also made of a material that is a poor conductor of heat.

[0025] This interrupts the heat transfer from bottom to top or top to bottom (vertical when installed) and also the heat transfer from outside to inside or inside to outside; here with both thermal breaks. The combination of features of the barrier-free threshold according to the invention has made it possible to solve all problems that were previously unsolved in the prior art, both for standards that meet Central European, particularly German, requirements, and for those that do not yet have such stringent requirements. Consequently, the threshold according to the invention can also be used in countries where such a high level of thermal insulation may not be necessary. The invention provides a suitable solution for both target groups and is universally applicable to both types of application.

[0026] As already mentioned, a drainage channel is connected to the preferably two grooves in which the magnetic sealing strips are arranged. According to the invention, the drainage channel is connected to both grooves in such a way that any escaping water is directed directly into the drainage channel. A further advantage is that the drainage openings can be arranged in the base body, particularly offset from the inner webs. This makes it possible, for example, to prevent moisture or water from being pushed back in strong winds, and at the same time to prevent water from penetrating these openings and thus into the drainage channel during driving rain and strong winds.

[0027] An advantageous development of the invention is characterized in that both thermal breaks can be inserted, in particular clipped, into recesses in the base body. These recesses in the base body are preferably arranged one on the outside and one on the inside next to the grooves for the magnetic sealing strips. This allows a base body to be manufactured very inexpensively, for example using the extrusion process for light metal profiles. In particular, the effort required for arranging or inserting the thermal breaks into the base body is considerably reduced because the recesses in the base body are arranged directly next to the grooves. As already mentioned above, it is advantageous that the thermal breaks are made of a different material than the base body, in particular of plastic. This results in excellent insulating properties and thermal separation.By providing two thermal breaks in the heat transfer path from outside to inside, it is possible to significantly improve the insulating properties of a threshold made particularly of light metal or aluminum. In addition, the lower end element is also made of a different material. Plastic is preferred here too. This also interrupts the heat transfer both from outside to inside and vice versa, as well as upwards and vice versa when viewed from the floor. The result is a completely optimized threshold that meets all thermal requirements. This threshold can also be used as a barrier-free threshold, particularly in old buildings or as a threshold during renovations, and also in so-called barrier-free living spaces or facilities and buildings.As already mentioned several times, the base body is made of light metal, especially aluminum, and can therefore be obtained very cheaply using the extrusion process.

[0028] The threshold according to the invention is further characterized by the fact that an outward-facing leg and an inward-facing leg of the base body are curved to the ground with a uniform curve. This uniform curve, as already mentioned at the beginning, serves to create a barrier-free transition as effectively as possible. This means that the threshold does not create any edges or steps; rather, this leg allows the user to overcome the threshold by rising slightly from ground level, before then descending slightly again on the other side of the threshold. This prevents the corresponding disabled vehicles or disabled facilities from becoming caught or jammed.

[0029] An advantageous embodiment of the invention is characterized in that a predetermined bending point is provided at the connection of the leg to the base body in order to adjust the leg to the level of the inner floor, for example, to bring it into a position that is aligned with the floor level of the inner floor. In the same way, a corresponding predetermined bending point can of course also be provided on the other side of the connection of the further leg to the outside, for example, to adjust this leg to the level of the outer floor. This means that the threshold can also be used in buildings whose rooms have different floor levels. Adjustment is very easy with the threshold according to the invention. For this purpose, as already mentioned, at least one of the sides of the threshold has a corresponding leg with a predetermined bending point in order to bring this leg to the level of the respective floor.

[0030] To further improve the bending of the leg, a recess is provided on the side facing the floor, at the respective predetermined bending point or opposite it. This recess serves to further facilitate the bending of the leg(s). However, it also serves to prevent breakage at that point. This is prevented by the special design of the recess, for example, as a rounded shape, seen in cross-section.

[0031] As already described above, a further development of the invention is characterized in that the downward-facing end profile, which is also designed to be attachable to the base body, is made of a different material than the base body, in particular a material with poor heat conduction, such as plastic. The advantages in this regard have already been described above.

[0032] The threshold according to the invention is also characterized in that, when the window or door is closed, the magnetic sealing strips interact with counter magnets arranged correspondingly thereon on the side facing the floor to seal a gap between the threshold and the bottom edge of the door. The threshold according to the invention is particularly characterized in that two magnetic strips are arranged next to each other (from the outside in) in the base body. Of course, the corresponding counter magnets are also located on the lower leg of the door or window, directly opposite each other. This means that the magnetic sealing strips are arranged on the side of the door or window facing the floor.

[0033] It has proven advantageous if the counter magnets are attached to a support that is attached to the window or door or embedded in the window or door. This allows the counter magnets to be attached to the support beforehand and then easily fitted precisely into the underside of the window or door. A further advantage of the invention is that the threshold not only has these two magnetic sealing strips in conjunction with the counter magnets as sealing elements, but it is also possible to provide additional seals with the threshold according to the invention, such as a corresponding floor seal on a weather strip, in order to further improve the overall sealing effect.Furthermore, it is of course also possible to install a sealing profile, such as a hollow profile, on the inside of the door facing the floor to further improve the sealing effect. This makes the thresholds for existing buildings almost as good in terms of sealing effect as new thresholds that can be recessed into the floor.

[0034] It is also advantageous if the counter magnets are each arranged or attached to individual supports and the individual support(s) has / have a pin on the side facing the underside of the window or door, by means of which it / they can be attached to the window or door. These pins are then inserted into, for example, pre-drilled holes.

[0035] Openings in the door or window at the bottom and attached similarly to dowels.

[0036] The threshold according to the invention is further characterized in that the counter magnet(s) themselves have a pin formed on the side facing the window or door, which can be inserted into the underside of the window or door, in particular can be fastened there. This is achieved, for example, by pressing or hammering in these counter magnets.

[0037] The counter magnet according to the invention has a concave surface on the side facing the threshold or the magnetic strip. This concave magnetized surface is characterized as a so-called north pole magnetized surface, preferably with a three-pole configuration in the sequence south pole, north pole, south pole. Advantageously, the pin provided on the counter magnet or on individual supports has a rib or thread to achieve a dowel-like effect.

[0038] The invention is distinguished by a further embodiment, which is characterized in that the counter magnet is designed as a strip and in one piece, and is capable of interacting with both magnetic sealing strips. This means that with a single counter magnet, it is possible to cover both magnetic sealing strips in width, thus achieving the desired magnetic effect when the magnetic sealing strip and counter magnet are positioned exactly opposite each other. The polarity in the integral counter magnet is designed such that the two magnetic sealing strips are attracted precisely when they are positioned opposite the counter magnet.

[0039] As already mentioned, one embodiment of the invention is characterized in that the respective leg is designed to extend outwards or inwards and can be adjusted to the ground by bending. In a preferred further development, it is now provided that one of the legs is longer than the other leg in order to compensate for a height difference between the outside and inside of several millimeters, for example between 5 and 10 mm, in particular up to 30 mm, by bending. This can of course also be provided for a height difference from the inside to the outside, in which the leg on the side where the ground is lower is designed to be longer in order to be able to compensate for the height difference in a much more favorable manner.

[0040] The invention is also characterized in that a connecting profile is provided as a height compensation profile, which can be fastened to the underside of the base body on the outside or inside facing side and or receives or carries an additional leg on the connecting profile for further height compensation between outside and inside.

[0041] The idea is to overcome certain steps, for example when an outdoor terrace is lower than the indoor area. The same naturally applies to outdoor areas, which can also be higher or at a different level than the indoor area. The height adjustment profile is then arranged on the inside of the threshold to create this height compensation. The connecting profile is designed so that it can be attached, for example, to the underside of the threshold, i.e. the side facing the ground. The additional leg is designed in such a way that on the one hand there can be an almost step-free attachment to the threshold, but on the other hand the escape of moisture or liquid from the drainage channel is not impeded.

[0042] Advantageously, the additional leg has a bend that can be inserted into a receptacle of the connecting profile, forming at least a form-fitting, but preferably a form-fitting and force-fitting connection. In order to provide further height compensation options, a predetermined bending groove is provided on the additional leg, with a correspondingly arranged recess preferably located opposite it. This makes it possible to compensate for corresponding height differences, analogous to the design with the predetermined bending point on the threshold itself. Of course, the invention also provides for a connecting profile with a corresponding additional leg to be provided, for example, pointing outwards, while a normal leg of the threshold is provided on the inside, likewise adjustable to the level of the floor. A reverse arrangement is of course also encompassed by the invention.

[0043] A favorable variant of the invention is characterized in that the connection profile holder is circular in cross-section or designed as a roller socket to accommodate a correspondingly designed roller of the additional leg or an intermediate piece. This is an extremely clever embodiment of the invention because it makes it possible to ensure the height compensation function without having to bend the material, for example, at a predetermined bending point. This can be achieved at a height that, for example, in a design with a predetermined bending point, could potentially lead to deformation, resulting in the material's structure being compromised to such an extent that it can no longer withstand permanent load.It is precisely for this case that the additional leg is arranged, for example, in an intermediate piece which is provided with the previously described pan-shaped design on the one hand and with a corresponding insertion groove for the additional leg on the other hand.

[0044] A further development of the previously described design is characterized by the fact that an end piece can be arranged on the connecting profile in a mounting groove provided thereon, in order to pivotally secure the additional leg or the intermediate piece arranged thereon. This end piece forms, so to speak, the upper limit of the roller socket when inserted into the groove. This makes pivoting very easy. Once the desired angle has been set, the intermediate piece can then be secured using the end piece.

[0045] It is also advantageous if a height adjustment device is provided on the side of the connecting profile facing the floor, which can be secured in a connecting groove formed on the connecting profile. This serves to prevent the connecting profile from tilting if the height difference is such that the connecting piece cannot be supported with a certain material. In order to avoid later settling or wobbling and the formation of cracks, the height adjustment device is extremely advantageous because it can be set to a selected height and then secured. For this purpose, for example, there is a plate-shaped support element in the lower area. This rests on the floor and engages the upper part of the height adjustment device by means of an adjusting screw. Once the thread has been set to the desired height, the height adjustment device can be secured using one or two lock nuts.As already mentioned, the design with an intermediate piece on the connecting profile is such that, for example, on the intermediate piece that carries the roller, an insertion groove is formed on the outward-facing side to accommodate the additional leg. This allows the additional leg to be inserted in any length. If, for example, the leg for the height compensation function is too long in terms of material, it is easily possible to cut off a section of the additional leg. This is usually done using standard machining tools and does not result in any material weakening.

[0046] The invention is also characterized in that a seal can be arranged on the side of the base body, in particular by means of a composite sheet. This seal serves to seal the outer area, for example outside a substructure, such as a balcony, an external terrace or the like, from the inner area. In this case, the area in which the thresholds are arranged is often neglected during construction. The seal is intended to seal this area safely and reliably. This prevents later construction defects from having to be rectified because this seal was forgotten. The seal can advantageously be attached to the base body by welding, cold or hot gluing. It is advantageously attached such that it is arranged on the threshold before it is finally fixed or fastened to the ground.The sealing membrane of the seal is designed so that it can, for example, be extended beyond the additional leg of the connecting profile. However, it should be extended beyond the area of ​​the height adjustment device, for example, in order to reliably seal this area as well. Extending further outwards, another sealing membrane can of course be connected or glued over, as usual.

[0047] A further aspect of the invention relates to a height adjustment profile, in particular for a threshold, as previously described. This height adjustment profile can be provided universally on thresholds, both on the outer and inner sides of this threshold. It consists of at least one connecting profile, an additional leg, and a height adjustment device. This height adjustment device, however, is also optional. The height adjustment profile can also be used without this height adjustment device, for example, when not so great height differences need to be compensated. As mentioned, the height adjustment profile has an additional leg that can be fastened to an intermediate piece according to a variant of the invention, in particular can be inserted into an insertion groove. This intermediate piece can, as already described above, be provided with an angled portion so that it can be inserted into a groove to secure the additional leg.Another design, however, also includes the intermediate piece being designed as a roller socket, wherein the roller socket has a receptacle into which a roller of the additional leg can be inserted, particularly pivotably. The advantages of such a design have already been described for the threshold and with a corresponding design. They also apply equally to the individual profile.

[0048] The invention also relates to a system-opening or system-closing element, such as a window or a door with a threshold, as described above, or with a height adjustment profile, as also described above. This system-opening or system-closing element is designed as a window or door in such a way that the space between the lower element part, i.e., for example, the door leaf and the threshold, is securely sealed. For this purpose, the invention provides, for example, two magnetic sealing strips that interact with counter magnets on the underside of the door or window. Advantageously, however, the invention also allows for further sealing elements to be provided, for example a profile seal that is arranged in a weatherboard, preferably, of course, on the outside of the window or door.Furthermore, it is possible to provide an additional profile seal on the inside of the system-opening or closing element, which also further seals the interior. This reliably prevents moisture from entering, and also reliably prevents cold penetration and heat loss through such a sealing arrangement on the door or window for a long time.

[0049] The invention is illustrated schematically in exemplary embodiments in the drawings. They show: Fig. 1a to 1c a first embodiment of a threshold not according to the invention, Fig. 2a to 2c variant of a threshold according to Fig. 1a bis 1c , Fig. 3a to 3c a further variant of the threshold not according to the invention, Fig. 4 a threshold not according to the invention with two thermal separations, Fig. 5 a variant of the Fig. 4 shown threshold according to the invention, Fig. 6a and 6b another embodiment of the threshold according to the invention, Fig. 7 a non-inventive embodiment of the threshold according to Fig. 4 with a modified counter magnet, Fig. 8a to 9 next embodiments of a threshold according to the invention with a bendable inner leg of different lengths, Fig. 10a a threshold not according to the invention with a connecting profile as a height compensation profile, Fig. 10b a first embodiment of a height compensation profile not according to the invention, Fig. 11a and 11b another variant of a height compensation profile not according to the invention, Fig. 12 a further embodiment of the threshold according to the invention with a one-piece counter magnet, Fig. 13 a further embodiment of the threshold according to the invention with a pivoting device for the inner leg, Fig. 14 a threshold not according to the invention with a connecting adapter and a widening, Fig. 15 a threshold not according to the invention with a connecting adapter and a water drainage channel in front, Fig. 16 a threshold not according to the invention with a connecting adapter, widening and water drainage channel, Fig.17a further embodiment of the threshold according to the invention analogously.

[0050] In the figures, identical or corresponding elements are designated by the same reference numerals and will therefore not be described again unless appropriate.

[0051] In the Figuren 1a bis 1c a first embodiment of a threshold 100 not according to the invention is shown. The base body 1 is located at least partially on the side facing inwards I. In Figure 1a, an inner leg 13 is provided, which can be bent towards the floor B. This is shown in dashed lines and denoted by the reference numeral 13c. The base body 1 contains the grooves 3 and 4 for receiving the magnetic sealing strips 5 and 6. The magnetic sealing strips 5 and 6 are attracted by counter magnets 81 when they are in register, i.e. when the door is closed. The door leaf is designated 8 here, while Figure 1b shows a frame which is designated 9. A first thermal break 11 thermally separates the base body 1 from the inner region towards the outer region. The base body 1 is further formed by the outwardly facing end element 2, which forms the lower end plate.This lower end element 2 defines the drainage channel 7, which runs outwards into the outlet 71 A. An outer leg 14 closes off the threshold to the outside, while the lower end plate or the lower end element 2 runs into the extension 21. The extension 21 is wide enough to allow a frame 9 of the door or French window to be attached there. This is indicated in Figure 1b. The frame 9 is attached to the threshold 100 by means of fastening screws, which are not designated in more detail. An adapter 90, which is shown in Figure 1c, is also used for this purpose. Figure 1b, of course, only shows the outer area, i.e. the area in which the frame 9 is visible.The extension 21 or the lower end element 2 has struts 22, which serve to support the extension 21 or the lower end element 2 and which, in particular, also serve to reduce the heat transfer from the threshold to the floor B. The counter magnets 81 are attached to a support, which is attached to the leaf of the door 8 by means of a screw as a fastening means.

[0052] In the Figuren 2a bis 2b A further embodiment of a speed bump not according to the invention is shown. The same reference numerals denote the same features or elements here, as in all other figures. In contrast to the solution according to Figur 1 the inner leg 13 is shorter than in the Figur 1a Otherwise, the design is roughly analogous to the Figuren 1a bis 1c . Therefore, the reference symbols will not be presented again.

[0053] In the Figuren 3a und 3b A further embodiment of a threshold 100 not according to the invention is shown. This differs from the previously presented embodiments in that no closing leg is provided on the inward-facing side. The level of the inner floor must therefore end at the upper edge of the threshold 100 or the upper edge of the base body 1 in order to ensure a barrier-free transition. Here, too, all other reference numerals are analogous to those in the Figuren 1 and 2 presented reference symbols have been used.

[0054] Fig.4 shows a further threshold 100 not according to the invention. The threshold 100 consists of a base body 1. In the base body 1, a first thermal break 11 and a second thermal break 12 are each arranged next to grooves 3, 4 for magnetic sealing strips 5, 6. The grooves 3, 4 are connected to a drainage channel 7 that extends along the underside of the base body 1. The outlet 71 is arranged on the side of the base body 1 facing outwards A. A lower end element 2 is provided on the side facing the floor B. This lower end element 2, just like the first and second thermal breaks 11, 12, is made of a different material than the base body 1. Plastic is preferably used in this case. In order to ensure sufficient stability of the aforementioned components, it is of course possible to use correspondingly fiber-reinforced plastic. However, the invention is not limited to this.On the side of the base body 1 facing inwards I there is an inner leg 13. On the side facing outwards A there is an outer leg 14. The threshold 100, schematically marked with an arrow, interacts with a door 8 or a window when used as intended. The drawing shows a side view of the door leaf. The counter magnets 81 are arranged on the underside of the door leaf so as to correspond to the magnetic strips 5, 6, so that when the door 8 is closed the magnetic strips 5, 6 are pulled upwards. As already mentioned, both grooves 3, 4 are connected to the drainage channel 7. This drainage channel 7 is designed so cleverly that it runs above the end element 2 and is guided over the floor in such a way that it can be guided outwards A without any problems.In particular, the outlet openings of the outlet 71, which are not designated in more detail, are offset from the inner webs 30, 40. This design prevents moisture from being forced inwards, for example by strong wind or driving rain. However, the outlet to the outside A is not impeded. A weatherboard 80 is provided on the door 8 on the side facing outwards A. The weatherboard 80 carries an additional seal 82 designed as a hollow profile. The weatherboard 80 is fastened to the door by means of a screw. Preferably, a seal is provided in the upper area of ​​the weatherboard 80 in order to prevent moisture from entering there as well. This can be, for example, a normal silicone seal 83, which is applied before the weatherboard is attached.Since the weatherboard 80 is designed in two parts, the screw, for example, can be installed in a concealed manner without being affected by moisture later on, thus preventing unsightly rust spots from forming.

[0055] Fig. 5 shows a variant of the Fig. 4 shown inventive threshold 100. The same reference numerals have been used as in Fig. 4 . The reference numerals are also used in the other figures so that the differences are only described again if necessary. In contrast to the Fig. 4 In the variant of the invention shown, the threshold 100 is provided with the inner leg 13, which here has a predetermined bending point 130 at the connection point of the leg 13 to the base body 1. This allows the inner leg 13 to be bent into a position 131. This takes place in direction b, i.e. directed towards the floor B, if, for example, the inner floor B is lower than the outer floor B. To make bending even easier, a recess 131 is arranged on the side opposite the predetermined bending point 130. This recess is, as can be seen, rounded, so that bending does not result in such a material change that breakage could occur. Furthermore, this recess 131 naturally makes bending in direction b easier.

[0056] The Fig. 6a, 6b and 7 (Fig. 7 is not in accordance with the invention) show a further embodiment of the speed bump according to the Fig. 4 and 5, but here with different, i.e. modified, counter magnets 81. As can be seen, the counter magnets 81 have a molded-on pin 842. This serves to fasten the counter magnet 81 in the leaf of the door 8 or the window. To do this, a corresponding hole must then simply be drilled in the door 8 in order to insert the counter magnet 81 with the pin 842. The principle here is that the hole is made somewhat narrower than the outer diameter of the pin 842, so that the pin 842 acts like a dowel. For this purpose, the pin 842 advantageously has a ribbing or a thread to achieve this dowel-like effect. Fig. 3b an enlargement of an embodiment of the counter magnet 81 is shown. It can be seen that this counter magnet 81 has a surface F on the side facing the threshold or the magnetic strip 5, 6. This surface F is advantageously concave. Furthermore, this north pole magnetized surface F is preferably provided with a 3-pole design, so that a sequence, for example south pole, north pole, south pole, is provided. This means that the magnetic sealing strips are also reliably attracted when the door is closed. This also achieves an extremely favorable sealing effect, since the concave design of the surface F prevents the penetration of wind, moisture and / or heat. Fig. 6a differs from Fig. 7 merely in that the leg 13 pointing inwards I is provided with a corresponding predetermined bending point 130 in order to bring this leg into a lower position 13', which is indicated by dashed lines. Fig. 7 This leg is fixed, i.e. it cannot be changed.

[0057] In the Fig. 8a , 8b und 9 The following embodiments of a threshold 100 according to the invention with a bendable inner leg of different lengths are shown. The same reference numerals have been used here as already described in the previous variants. As can be seen, however, a threshold 100 is shown here which has larger dimensions in terms of width (seen in section) than the previously presented variants. Otherwise, the same reference numerals have been used here as before. In contrast to the variants shown so far, the door 8 has a recess on the underside into which a support 84 is embedded. This support 84 can be attached to the door 8, for example, by means of fastening screws. This support 84 carries the counter magnets 81.

[0058] Furthermore, it can be seen that an additional seal 85 is provided on the side facing inward I to further increase the overall sealing effect. A predetermined bending point 140 is provided on the outer leg, or rather its connection to the base body, to also provide compensation here if necessary. All other reference numerals have already been introduced and are used again here in the same way. Fig. 8a , 8b und 9 differ only in that the leg 13 of the base body 1 pointing inwards I has a different length, so that it can be bent to different depths, as indicated by the dashed position 13 1 of the leg 13. For example, the leg 13 pointing inwards is significantly longer than the leg 14 pointing outwards A. This allows it to be bent much further, so that height differences of several millimetres, for example 5 to 10 mm, in particular up to 30 mm, can be compensated.

[0059] Fig. 10a shows a threshold 100 not according to the invention with a connecting profile 14 as a height adjustment profile H. This connecting profile 15 is fastened to the underside of the threshold 100. This is done using conventional fastening means, such as at least one screw. The connecting profile 15 has an additional leg 16, which is provided here on the side facing outwards A. This additional leg 16 can be bent in the direction b in a position indicated by 161. In order to compensate for certain dimensional tolerances, a height adjustment device 17 is provided, which can be fixed in a connecting groove 152. As can be seen, the height adjustment profile can be fixed, for example, using corresponding lock nuts. The height adjustment profile H is designed in two parts, namely with the connecting profile 15 and the additional leg 16, as shown in the Fig. 10b is shown. To make turning easier, a predetermined turning groove 160 with a corresponding and oppositely formed formation 161 is again provided. The additional leg 16 can be inserted into a receptacle 151, for example with an angled portion 162. This allows assembly such that, for example, the connecting profile 15 is first fastened to the threshold 100 and then, when the threshold 100 is also fixed to the floor B, the additional leg 16 is inserted. Such a configuration is particularly advantageous when larger height differences between the outside A and the inside I have to be overcome. The threshold 100 designed in this way with the connecting profile 15 or the height compensation profile Hauch helps to create a transition that can essentially also be overcome by disabled vehicles or devices for the disabled.Such a threshold is particularly advantageous for use in the renovation of old buildings, as such height differences are often found there. Leveling the floors by filling them is generally very costly and requires, in particular, appropriate sealing, which regularly leads to difficulties. This can be remedied by a height adjustment profile H. This height adjustment profile H can be arranged both, as shown, on the outward-facing side A of the threshold 100, or, in an embodiment not shown, on the inward-facing side I.

[0060] In the Fig. 10a It is also shown that the inner leg 13 is also designed to be bendable into position 13. A seal 18 is attached to the underside of the threshold 100 or its base body 1 by means of a composite sheet 19.

[0061] In the Fig. 11a und 11b a further variant of a height adjustment profile H is shown, not according to the invention. This profile is also characterized by a connecting profile 15, which, however, here has a receptacle 151, which, viewed in section, is circular or designed as a roller socket, in order to receive a correspondingly designed roller 164 of the additional leg 16 or of an intermediate piece 163. In the Fig. 11b the height adjustment profile H is enlarged and shown as an individual illustration. It can also be seen that the intermediate piece 163 has an insertion groove 165. This can now accommodate an additional leg 16 formed at the end corresponding to the insertion groove 165. This additional leg 16 can then be kept in a width that is sufficient to overcome a wide variety of widths. In order to make adjustments on site, it is then easily possible to cut off a piece from the additional leg 16. This is done using conventional machining tools, such as a suitably designed milling machine or saw. Once the roller 164 of the intermediate piece 163 has been inserted into the receptacle 151, an end piece 153 is inserted into a fastening groove 154 provided for this purpose to secure the intermediate piece 163 in the desired position. This closes the roller socket, so to speak, and the intermediate piece 163 can no longer slide out.

[0062] In Fig. 12 A further embodiment of the threshold 100 according to the invention is shown. Here, only the counter magnet 81 is formed in one piece. This means that the counter magnet 81 is designed such that its width is exactly above the magnetic sealing strips 5, 6 when the door is closed, in order to then attract both magnets. The polarity of the counter magnet 81 is such that it acts exactly like individual counter magnets, accordingly, a polarity of south pole, north pole, south pole and south pole, north pole, south pole would be provided, for example. Otherwise, the Fig. 12 The embodiment shown is essentially identical to that shown in Fig. 6a shown variant.

[0063] Fig. 13 shows a further embodiment of the threshold according to the invention with a pivoting device 200 for the inner leg 13. As can be seen, the pivoting device is designed as it is, for example, in Fig. 11a or 11b for the connecting profile 15. Accordingly, the leg has a tubular configuration on its side facing the threshold 1, which is inserted into a type of ball joint at the inner end of the threshold 1. This allows the inner leg 13 to be easily arranged at the lower floor level on the inside of the threshold 1. As can be seen, the thermal breaks (not designated here) are also designed differently than in the previous embodiments.

[0064] Accordingly, this variant of a threshold according to the invention represents a further development, in particular of the main subject matter of this patent application IL d, and can be combined with both the main claim and the subclaims. The design is shown here with a window or door profile as a plastic profile. A further feature to be noted in this embodiment is that an additional seal 84, designed here as a lip seal, is arranged on the side of the door leaf 8 facing the inside. This further improves the tightness of the entire system. This makes installation extremely easy to service, since both lower floor areas and, to a certain extent, higher areas on the inside of the threshold can be easily adjusted.

[0065] Fig. 14 shows a threshold not according to the invention with a further connection adapter 301. This further connection adapter 301 is arranged on a connection profile 15, wherein the further connection adapter 301 can engage as a clip connection in a recess provided on the connection adapter 308. The further connection adapter 301 is designed such that it can accommodate an extension 300. At the output end of the extension 300, on the side facing the ground, a further height adjustment device 304 is provided. A further interface 303 is also arranged on the outer edge of the extension 300, so that it is possible to connect a further adapter there in order to attach completion elements or extensions there.Otherwise, the embodiment shown here is to be considered with regard to the reference numerals in the same way as the previous figures, i.e., the same features have been provided with the same reference numerals.

[0066] Fig. 15 shows an embodiment of the threshold not according to the invention with a connection adapter 308 and a water drainage channel in front, consisting of a connection piece 307 and an end-side outlet piece 309, wherein a cover grille 308 is provided between these two elements. A height adjustment device 17 is arranged below each water drainage channel. An insulating layer 500 is provided on the rough side beneath the threshold, which further improves the thermal insulation from the outside to the inside. Of course, a seal for the outer sealing membrane is also provided here, which is not further designated in this figure. Otherwise, a plastic element is also shown here, which has an additional seal 84 on the rough side. Otherwise, the features in this embodiment have also been designated as in the previous embodiments of the invention.

[0067] Fig. 16 shows a speed bump not according to the invention with a connection adapter 308, a widening 300, as in Fig. 14 described as well as a water drainage channel, as in Fig. 15 described. The same reference numerals were used here as well. It is clear that the design of the adapter 308 and the widening 300 can be cleverly used to arrange even further elements - for example at the interface 303 - on the widening 300. This is also done with the clip connection. Above this, a connection profile is shown, whereby this connection profile is designated here with the reference numeral 400. 401 designates a further interface into which a connection profile 402 can be pivoted and then clipped, as can be seen from the dashed lines. The outlet-side base bears the reference numeral 310; all other reference numerals have already been presented in the previous figures.

[0068] Fig. 17 shows a further embodiment according to the invention, which is almost analogous to the one in Fig. 5 and 6a The essential difference here is the modified design of the thermal breaks 11 and 12, as well as the profile design for the window and modified door elements. Here, too, a design of a plastic profile is shown, in which all other elements, as already presented, are also present. Therefore, a repeated presentation is omitted.

[0069] Fig. 18 shows a variant of the speed bump not according to the invention, as shown in Fig. 16 has already been presented. However, here there is no widening between the threshold 1 and the water drainage channel with cover grille 306 and outer edge 309; instead, the water drainage channel is attached directly to the adapter 308, which is attached to the threshold 1.

[0070] Fig. 19 shows a threshold according to the invention, which is analogous to the one in the Fig. 8b and 8c. However, here, a plastic element is provided as the window or door element. The inner edge 13 can be adjusted to the floor level, as can be seen.

[0071] The Fig. 20 and 21 also show thresholds not according to the invention with a connecting profile, as is shown for example in the Fig. 11a und 11b This connecting profile has the reference number 15, whereby an outer additional leg 16 is provided, which, as in Fig. 11a or 11b, is arranged in a receptacle designed, for example, as a roller socket. The inner leg 13 is also designed to be bendable, as already presented in the previous figures. The difference between Fig. 21 and Fig. 20 is the somewhat shorter design of the inner leg 13. Otherwise, a plastic element is also shown here as the door or window element. It should be noted that in all the figures shown, which were presented here in wood or plastic versions, it is of course also possible to use aluminum elements as the window or door element. The threshold according to the invention is therefore universally applicable for wood, plastic, or aluminum profiles.
