Description

TITLE

ACCESSIBLE FLOOR SILL FOR DOORS

TECHNICAL AREA

The present invention relates to a barrier-free threshold for doors, in particular for front doors and side entrance doors.

STATE OF THE ART

Door thresholds are usually structures that protrude from the floor, which cover butt joints in the floor and serve as a lower stop for the door leaf. Such door sills form an obstacle for wheel-bound aids, such as wheelchairs, walkers, strollers and the like. They also create pitfalls, especially for small children and people with walking difficulties. In modern buildings, therefore, barrier-free thresholds are used that can be rolled over. These thresholds are embedded in a recess in the floor and can be easily rolled over. Some of these thresholds work together with lowerable door seals so that there is sufficient protection against noise and drafts and preferably also against driving rain.

In other embodiments, the thresholds still rise above the floor, but usually a maximum of 15 to 20 mm. These embodiments also have a run-on slope or they are designed as semicircular sleepers.

PRESENTATION OF THE INVENTION

It is an object of the invention to provide a barrier-free threshold for doors, which is particularly suitable for renovation buildings.

This object is achieved by a threshold with the features of claim 1. The barrier-free threshold according to the invention for a door has a base profile and a first ramp which can be connected to the base profile. The base profile has a first leg and a second leg and a middle part arranged between these two legs, the two legs being designed to rest on a floor. The base profile can be fastened to the floor by means of at least one of these two legs. The middle part has a flat and horizontally extending surface directed upwards towards the door leaf, which surface forms a sealing surface for a door seal attached to the door leaf. The first ramp adjoins the surface almost without steps and it extends over the first leg. It protrudes from this on a side facing away from the middle part. It preferably connects completely without steps.

It is simply constructed and can be quickly assembled. It does not require recesses in the building floor, so that it can be used in particular when renovating buildings. The barrier-free threshold does not require water channels, it not only offers optimal protection against drafts and noise, but despite its low height it also provides optimal protection against driving rain.

Thanks to the basic profile, optimal thermal separation can also be guaranteed. At least the middle part is preferably designed to be thermally insulating. The entire base profile is even more preferably thermally insulating.

The threshold preferably has a second ramp which adjoins the surface almost without steps.

In one embodiment, it can be connected to the base profile, it extends over the second leg and projects beyond it on a side facing away from the central part. It is preferably attached in the same way and / or configured in the same way as the first ramp.

In another embodiment, the base profile and the second ramp are formed together in one piece. Apart from the fastening screws and any corner connectors, the threshold preferably has no further components, so that it can be produced inexpensively and assembled in a simple manner.

The second ramp is preferably of the same design as the first ramp. This also reduces manufacturing costs and simplifies assembly.

The base profile is preferably made of plastic. This makes thermal insulation and thermal separation easier to achieve. The first ramp and / or, if present, the second ramp preferably consists of metal, in particular aluminum. The threshold is therefore robust.

The base profile and the ramps can each be composed of several parts. However, the base profile and / or the ramps are preferably each formed in one piece. In a preferred embodiment, the base profile and the two ramps form three separate components.

In another embodiment, the base profile and one of the ramps are jointly formed in one piece, so that the set of these components consists of two components. Depending on the design of the components, the leg of the base profile is formed in the area of the middle part, in the area of the second ramp or in an intermediate area.

In the case of a common one-piece design of the basic profile and the second ramp, the common component is preferably made of plastic. The base profile and the second ramp can be made of the same plastic or they can be made of different plastics. Furthermore, the ramp can still be made of metal and the base profile made of plastic is molded onto it. The two-part variant of the threshold according to the invention with the ramps on both sides can be made very narrow.

To facilitate assembly, the first ramp and / or, if a separate component available, the second ramp can also be connected to the base profile by plug-in and / or clamp connections. This eliminates the need for assembly tools.

The threshold can also be easily installed if the base profile can be attached to the floor using screws. Preferably, the first ramp and / or, if present as a separate component, the second ramp cover the screws, so that they are not accessible to everyone in the assembled state of the threshold. In addition, the screws are no longer visible. The threshold is particularly suitable for use in renovations when the first ramp and / or, if present, the second ramp have at least one articulated groove in order to arrange at least one area of the ramp at an angle to the remaining area of the ramp. This allows the threshold to be adjusted to different floor levels in the interior and exterior of the door. If the ramps are separate components, at least a part of the region projecting beyond the first or second leg is preferably arranged at an angle to the remaining region of the ramp.

Preferably, the first and / or, if available as a separate component, the second ramp has a stop surface with which they abut an end face of the first or second leg in the assembled state. This ensures that the ramps are not moved.

So that the threshold can be walked on safely, the first and / or, if present, the second ramp preferably has an upward, non-slip surface.

As an alternative or in addition to screw connections, the base profile can also be glued to the floor. In addition, it is advantageous to install seals between the floor and the threshold, especially against moisture. The threshold therefore preferably has adhesive and / or sealing grooves in the base profile.

The threshold is designed depending on the type of floor. One embodiment can be used on a flat floor. Other embodiments can be used on floors which have one or more depressions. Depending on the embodiment the threshold also has a gutter for water, especially rainwater. The channel is preferably part of a ramp. The channel is preferably formed in one piece with part of the threshold, preferably with a ramp. If the at least one ramp is designed as a separate component in comparison to the base profile, a set or a modular threshold system can be formed, which allows the threshold to be used with differently shaped floors while maintaining a constant base profile by using differently shaped ramps .

A system according to the invention has the threshold according to the invention and a door seal, the door seal having a sealing bar which can be raised and lowered mechanically and which, when the door leaf is closed, lies sealingly on the planar and horizontally extending surface of the base profile which is directed upwards towards the door leaf. This optimizes protection from the outside world, for example from drafts, noise and driving rain.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

A typical entrance door, for example a front door or a side entrance door, is shown schematically in FIG. An interior area of a building is provided with the reference symbol I in this figure, an exterior area with the reference symbol A. The door has a door frame R and a movable door leaf F. A threshold S according to the invention is arranged in the lower part of the door frame R. It usually covers a joint between a floor of the inner region I and a floor of the outer region A. In the door leaf F there is a door seal D which acts downwards. In this example, this is a mechanically lowerable door seal, which is automatically actuated when the door leaf is closed and sinks to the threshold S. For this purpose, an actuation button usually protrudes on at least one end face of the door leaf, which is pressed in on the door frame when the door is closed and thereby actuating a spring-loaded lowering mechanism. When the door is opened, the operating button is released again and a lowered sealing strip of the lowering seal is raised again. Instead of a lowering seal, grinding and brush seals can also be used.

The threshold S together with the door seal D should protect against drafts and noise. It should preferably also withstand driving rain. Furthermore, the threshold S is intended to form a thermal separation of the outer area A from the inner area I, that is, to avoid a cold bridge.

The interaction of the lowering seal D with the threshold S is shown in FIGS. The lowering seal D shown here is known. It has proven itself particularly for protection against driving rain. It has a housing rail 4 with a sealing strip 5, 6 which can be raised and lowered therein. The sealing strip has a carrier rail 5 and a sealing profile 6 fastened thereon. The housing rail 4 and the carrier rail 5 are preferably made of aluminum and the sealing profile 6 made of silicone or another material suitable for sealing. The lowering seal also has at least one actuating means and a lowering mechanism. These are well known and are therefore not shown here. The lowering seal can be attached to or in the door leaf F in different ways. In this example there are front-side mounting brackets 7. In Figure 2 the seal is shown in the raised state, in Figure 3 in the lowered state. As can also be clearly seen in FIGS. 2 and 3, the threshold S has a base profile 1 and a first ramp 2 and a second ramp 2 '. The two ramps 2, 2 'are preferably made of a metal, for example aluminum. The base profile 1 is preferably made of a thermally insulating material. It preferably consists of a plastic.

The base profile 1 and the two ramps 2, 2 'are each preferably formed in one piece. The second ramp 2 'is preferably of the same design as the first ramp 2. The base profile 1 is preferably mirror-symmetrical along its longitudinal central axis educated. The base profile 1 and the two ramps 2, 2 'preferably have a cross section which is substantially or completely constant over their length. As a result, they can be cheaply produced by the meter and shortened to the desired length.

The base profile 1 is designed to rest and attach to the floor. It lies on the floor both inside and outside the building. In the area of the building joint, the base profile 1 preferably has a spacing, here in the form of a central groove 11. In other embodiments, there is no spacing.

The base profile 1 has an upwardly directed, flat and horizontally running surface 100 which forms a sealing surface and which, together with the lowered sealing strip, takes over the protective functions mentioned above (draft, sound, water). In Figure 2 the door is open and the sealing strip 5, 6 is thus raised. In Figure 3, the door is closed and the sealing strip 5, 6 is lowered.

The following description is given with reference to FIGS. 4 and 5. The base profile 1 has a central part 10 and one leg 13, 13 'adjacent to each longitudinal side of the central part 10. The middle part 10 forms the sealing surface 100 mentioned above. This is arranged above the two legs 13, 13 '. The central groove 11, which is open at the bottom, is formed on the underside of this surface. It preferably has a rectangular cross section. On both sides of the central groove 11 there is preferably at least one sealing groove 12, 12 'which is open at the bottom. In this example, they have a semicircular cross section. Silicone or another sealing compound can be introduced into these sealing grooves 12, 12 '. The mass introduced can additionally or alternatively have an adhesive effect and thus also connect the base profile 1 to the floor. In this example, the sealing grooves 12, 12 'are formed in the middle part 10. Alternatively or additionally, they can also be formed in the legs 13, 13 '. In the figures, the reference symbols 18, 18 ′ denote a further sealing and / or adhesive groove.

The two legs 13, 13 'form downward surfaces, which as Support surfaces 19, 19 'are designed to rest on the floor. In the region of its respective free end, ie facing away from the middle part 10, an adhesive groove 16, 16 'which is open at the bottom is arranged in each leg 13, 13' in order to glue these regions onto the floor. If a silicone compound or another suitable adhesive sealing compound is used, sealing is also carried out at the same time.

The free ends of the legs 13, 13 'preferably each form a vertical stop surface. A through hole 15, 15 ', which extends in the longitudinal direction of the threshold S, is formed in the central region of each leg 13, 13', depending on the shape of the outlet. This through hole 15, 15 'is used in this embodiment for screw connection or for a different type of connection for corner connections to the door frame R. However, it is also possible, for example, to fasten the threshold in a different way in the area of the door frame.

As can be clearly seen in FIG. 4, the base profile 1 can be fastened to the floor by means of screws 3 or other suitable fastening means. The screws 3 pass through the legs 13, 13 'in a recessed area 14, 14', so that they preferably do not project above the legs 13, 13 '. The through holes for these screws 3 can already be formed in the legs 13, 13 '. As can be seen in FIG. 5, however, a small notch or some other type of marking is sufficient to make the screw connections in the correct place during assembly. The ramps 2, 2 'form a stepless widening of the sealing surface 100. They are flush with this surface and preferably first run in the horizontal direction before they each run towards the floor in an inclined surface. They extend above the legs 13, 13 '. They protrude the legs 13, 13 'at their free end facing away from the middle part 10 until they run out almost flat or almost completely flat on the floor. They have a correspondingly flat support surface 27, 27 'in the area which projects beyond the legs 13, 13'. This area is called the second or lower ramp section 21 here. The height of the threshold is preferably 5 mm to 8.5 mm, preferably a maximum of 6.5 mm. The width of the threshold is preferably 50 mm to 200 mm, preferably a maximum of 140 mm. The surface of the inclined area of each ramp 2, 2 ', here called the first or upper ramp section or ramp part 20, is preferably designed to be non-slip. This can be achieved, for example, by choosing the appropriate surface material, for example by means of a coating. This inclined area is preferably provided with an anti-slip device 220 in the form of longitudinal ribs which protrude upward from a tread surface 22. The tread surface 22 preferably extends over the upper and lower ramp sections 20, 21.

In the area of the lower ramp section 21 there is an articulated groove 25, 25 'which is open at the bottom. It preferably has an essentially triangular cross section. As can be seen from the overview of FIGS. 5 and 6, the inclination of the lower ramp section 21 can be adjusted by means of this kink groove 25, 25 '. The threshold S thus compensates for differences in height between the floors on the two sides of the door, for example the floors on the inside and the outside of the building.

The two ramps 2, 2 'can be attached to the base profile 1 in a simple manner. The attachment is preferably carried out without tools. The ramps 2, 2 'can preferably be clicked into the floor profile 1. This is preferably done after the base profile 1 has been attached to the floor.

The base profile 1 has a horizontally oriented groove 101, 101 'between the central part 10 and each leg 2, 2', which preferably extends over the entire length of the threshold S. Each ramp 2, 2 'has a laterally projecting latching lug 24 at the free end of the first or upper ramp part 20. The upper ramp part 20 also has on its underside a downwardly projecting lower latching lug 23, 23 ', which is preferably provided with a barb. The counterpart to this is found in each leg 13, 13 'in the form of an open, undercut locking groove. The lower ramp part 21 is from the upper by a downwardly projecting foot 26, 26 ' Ramp part 20 divided. This foot 26, 26 'forms a vertical stop surface and is then followed by the above-mentioned kink groove 25, 25'.

As can be clearly seen in FIGS. 7 to 9, when installing the threshold, the base profile 1 is first attached to the floor, then the lateral latching lug 24 of the first ramp 2 is pushed into the corresponding groove 101. The first ramp 2 is pivoted downwards and the lower latching lug 23 is pressed into the latching groove 17. As a result, the foot 26 slides down along the free end of the leg 13 and lies against the end face thereof. The foot 26 thus forms a stop surface. The first ramp 2 is thereby secured. It can no longer be raised and can no longer be pushed away from base profile 1 and the door. In addition, as can be seen in FIG. 4, it covers the fastening screws 3 of the first leg 13 of the base profile 1.

The second ramp 2 'is fastened in the same way. It does not matter whether the first or the second ramp 2, 2 'is installed first.

FIGS. 10 and 11 show the threshold S with shortened ramps 2, 2 ′ in order to make the individual grooves and areas of the base profile 1 clearly recognizable in these representations. The ramps 2, 2 'are in reality preferably of the same length or approximately the same length as the base profile 1 and thus cover this completely except for the sealing surface 100, preferably over the entire length of the threshold. In the illustration according to FIG. 11, the length is the vertical sheet direction.

FIG. 12 shows a second embodiment of the threshold according to the invention. This threshold has the advantage that it can be made narrower than in the first embodiment. In addition, it has fewer individual parts.

In this embodiment, the second ramp is formed in one piece with the base profile 1. The corresponding component is designated here with the common reference number 1. The second ramp is represented by the areas designated by reference numerals 120 and 121. The elements designed as a common component, base profile 1 and second ramp 120, 121, are preferably made of plastic. In this example they are made from the same plastic. However, they can also consist of different plastics or the second ramp 120, 121 consists of a metal and the base profile 1 made of plastic is molded onto it. Other variants are also possible.

The base profile 1 in turn has a central part 10, which forms an upwardly directed, horizontally running support surface 100 for the sealing support of a door seal, in particular a lowering seal.

The first ramp 2 is in turn arranged on a first side. This is of the same design and fastened in the same way as in the first embodiment. The base profile 1 is also configured on this side in the same way as in the first exemplary embodiment. The same reference numerals designate the same elements as in the first embodiment. The base profile 1 is in turn fastened on this side by means of the screw 3, which is covered by the first ramp 2 and is therefore not visible in the assembled state of the threshold. The second ramp, which like the first ramp 2 has an upper ramp section 120 and a lower ramp section 121, runs on the other side of the threshold. However, as already mentioned, this second space 120, 121 is formed in one piece with the base profile 1. The sealing surface 100 and the second tread surface of the second ramp are thus formed together. This area is therefore narrower.

The second ramp in turn has an anti-slip device 220, preferably in the form of knobs or protruding ribs. Furthermore, there is preferably also a second kink groove 125, with which the lower ramp section 121 can be angled with respect to the upper ramp section 120 and the central part 10.

This side of the threshold is preferably not fastened by means of a screw, but is preferably glued on. For this purpose, there is at least one corresponding adhesive groove in base profile 1. In the example shown there are two Adhesive grooves 16 ', 18' shown. The adhesive grooves 16 ', 18' can alternatively or additionally also be used as sealing grooves. Depending on the embodiment, it is also possible not to fasten the threshold on this side of the floor. The first ramp 2 is preferably located on the inside of the building and the second ramp 120, 121 on the outside. Another arrangement is also possible.

FIG. 13 shows how the threshold described above is arranged on a flat floor B that has no significant elevations and depressions. A variant of the threshold described above is shown, the threshold shown in FIGS. 1 to 14 being attachable to floor B in the same way. In the variant shown here, there is no articulated groove. In addition, the two ramps 2, 2 'do not have a continuous support surface, but instead have pillars directed downwards with corresponding cavities.

FIG. 14 shows a second exemplary embodiment of the threshold according to the invention. The structure is essentially the same as in the first exemplary embodiment and is no longer described in detail here. The variants mentioned above can also be used in this exemplary embodiment. This threshold is designed to be arranged in a depression B 'of the floor B, the two ramps 2, 2' resting on the floor B outside the depression B '. The floor clamp, preferably the base profile 1, is attached to the floor. The fastening means already mentioned, such as screws and / or adhesive, are suitable for this. The central groove 11, the first sealing groove 12, the first recess 14 for the hidden fastening by means of a screw, not shown here, and the further sealing groove 18 can be seen in the figure. The grooves and depressions opposite the central groove 11 can also be seen, but are not shown in the figure. For this purpose, reference is made to the preceding figures. Since this threshold is mostly in the depression B 'of the floor B, the ramps 2, 2' can be formed with a minimal slope. As a result, the threshold does not pose any obstacle to entering a building. Thanks to the depression B 'in floor B, the threshold can be designed to be virtually barrier-free. The depression B 'is usually created on site, for example, by sharpening or digging up the existing soil.

FIG. 15 shows a third exemplary embodiment, which in turn essentially corresponds to the second and thus also the first exemplary embodiment, so that reference is made to the descriptions there. The third exemplary embodiment is suitable for use with a floor B which, in addition to the first depression B ′ into which the base profile 1 is inserted, has a second depression B ″ which is arranged in the outer region A with respect to the building. This second depression B "serves to receive a rain gutter, which is formed by the second ramp 2". For this purpose, a groove 210 ″ is formed between the upper leg section 20 ″ and the lower leg section 21 ″, which is open at the top and is preferably U-shaped in cross section. The channel 210 'has in the upper region of its two side walls inwardly projecting webs 211'. A cover 212 'lies on these webs 211'. The cover 212 'preferably has holes or slots so that water, in particular rainwater, can get into the channel 210' and can be carried away there via a drain (not shown). The cover 212 'is preferably made of metal. It is preferably easy to remove and reinsert for cleaning the channel 210 ′. Depending on the embodiment, the channel 210 'is designed as a separate component which is detachably or non-destructively connected to the upper and lower ramp sections 20', 21 '. In the preferred embodiment shown here, the groove 210 'is formed in one piece together with the upper and lower ramp sections 20', 21 '.

The embodiments according to FIGS. 16 and 17 are suitable for adapting level differences in the floor. These embodiments preferably again have the base profile 1, the first ramp 2 and the second ramp 2 '. As in the previous examples, the two ramps 2, 2 'can be latched into the base profile 1 by means of latching lugs 23, 23' and can thus be fixed. As in the previous examples, the base profile 1 can be fixed on the floor B by means of screws 3. The screws 3 are not shown in all figures. The corresponding notches in the depressions 14, 14 'can, however, be seen in the figures. Alternatively or additionally, the base part 1 can be glued to the floor, as already described above. For this purpose, adhesive grooves and / or sealing grooves 12, 12 ', 16, 16' are preferably provided. In the embodiment according to FIG. 16, the first depression B ′ is present in the floor B in the area of the door, the floor B going to a first area (outside area A or inside area I) into a lower step C than to the other area. The second stage C 'is correspondingly higher. The second ramp 2 'is in turn subdivided into two ramp sections 20', 21 'by the downwardly projecting second foot 26'. The two ramp sections 20 ', 21' both run horizontally and are aligned with one another. The second ramp 2 'is aligned with the second stage C and ends in a blunt stop on the inside of the second stage C. It is preferably on this

On the inside, even if a small distance is shown in FIG. The first ramp 2 has a preferably flat underside. Its upper side is also preferably designed to run in the horizontal direction except for an inclined free edge region 213. The first foot 26 'preferably serves as a stop for the inside of the first step C of the depression B' of the bottom B.

In the embodiment according to FIG. 17, the bottom B has a step C only on one side. There is no depression in floor B. The base part 1 and the first ramp 2 are therefore preferably designed in accordance with the embodiments in FIGS. 1 to 13, the underside of which can be designed differently from these examples. This design of the lower or upper side according to the embodiment in FIG. 17 can, however, also be applied to the previously described embodiments in accordance with FIGS. The second ramp 2 'corresponds to the first ramp 2 according to FIG. 17. It is therefore essentially horizontal, except for the inclined edge region 213', which, as in the example according to FIG. 16, ensures a smooth transition to floor B. The second foot 26 'is again on the inside of step C and serves as a side stop for the threshold S.

The embodiments according to FIGS. 18 and 19 are particularly suitable for entrance doors as well as patio and balcony doors. But they can also be used in other areas. In this embodiment according to FIGS. 18 and 19, the first ramp 2 corresponds to the first ramp 2 according to FIG. 16 and thus also to the second ramp 2 ′ according to FIG. 17. The base part 1 is designed in the same way as in the previous exemplary embodiments. It can be fixed on the floor using screws, not shown or attach to the floor using a suitable adhesive or sealing material.

The second ramp 2 'according to the exemplary embodiment shown in FIG. 18 is also essentially of the same design as the first ramp 2. However, it has an elongated second ramp section 21'. This extended second ramp section 21 'runs on the upper side in alignment with the first ramp section 20' and in the horizontal direction. Anchoring elements 215 'are attached to the underside of this extended second ramp section 21', which enable the second ramp 2 'to be anchored in the filler material G of the terrace or balcony floor. The

Anchoring elements 215 'can be designed differently. In this

Embodiment they are designed in the form of partially circular grooves which project downwards and are open at the bottom. The grooves preferably run over the entire length of the threshold S. Depending on the type of building, the filler material G is split, gravel, concrete or another material. FIG. 18 shows a concrete plate T adjoining the filling material G, FIG. 19 shows a plate P placed on the filling material G. The plate P consists, for example, of wood, concrete, stone or porcelain stoneware. In both FIGS. 18 and 19, the second ramp 2 'forms a fastening surface for fastening an insulation or protective mat or foil O. This will

Usually attached as standard on the outside of a building to protect the building's outer wall against water and moisture, for example in the ground. This film O can be connected to the threshold S in the area of the door in order to create a tight connection and protection against water in this area. The film is usually glued on. A bitumen layer is preferably used.

In preferred embodiments, the threshold S according to the invention is already provided with a corresponding adhesive layer. In the embodiment according to FIG. 18, the fastening surface is marked by a

Insert element 28 'in the form of a plane-parallel plate, preferably made of metal or plastic. The insert element 28 'has a thickening, called the fastening head 280', at one end. This fastening head 280 'can be made into a Clamp the receiving element 214 'directed below. In this embodiment, the receiving element 214 'has the same shape as the anchoring elements 215'. It is thus also formed by a part-circular, downwardly open and downwardly projecting groove. The identical design has the advantage that there are thus several positions for the attachment of the insert element 28 'and the position of the threshold S can be selected on site in accordance with the structural conditions. The film O can be glued to the plane side of the insert element 28 ′ facing away from the base part 1 and extending in the vertical direction. The opposite side of the insert element 28 'is preferably on the outer wall of the building, even if a small distance is shown in the figure

In the embodiment according to FIG. 19, the fastening surface is formed by an arm 29 'running in the vertical direction, which is preferably formed in one piece with the other parts of the second ramp 2'. The second ramp section 21 ', i.e. the section starting after the second foot 26 'is relatively short and merges into the arm 29' at a preferably right angle. The arm 29 'is preferably formed by a plane-parallel plate which is formed at recurring intervals, preferably with notches 290' or other types of predetermined breaking points or material weakenings. This allows the length of the arm 29 'to be adapted to the conditions of the building on site.

The surfaces of the ramps 20, 20 'of the embodiments according to FIGS. 14 to 19 are preferably also designed to be non-slip. However, since they are less steep than in the first exemplary embodiment or run essentially or completely in the horizontal direction, knobs or elevations are not absolutely necessary for this.

As can be clearly seen from the overview of FIGS. 13 to 19, thresholds S can be formed in a variety of ways with a few basic elements and adapted according to the local conditions. The basic profile 1 is the same in all of these embodiments. Depending on the shape of floor B, the first and the left ramp are identical, as shown in FIG. This embodiment is particularly suitable for renovations when a threshold is placed on a flat floor. If there is a recess in the area of the door, you can use the Click on base profile 1 according to FIG. 13 differently designed ramps 2, 2 ', these two ramps again being of identical design, but having a lower inclination in comparison to the example according to FIG. This can be seen in FIG. 14. If there is a depression, but there are different levels of the floor on both sides of the depression, the second ramp 2 "can be formed according to FIG. 16. Depending on the embodiment, the first ramp 2 again corresponds to the first ramp 2 according to FIG. 14 or the shortened one first ramp 2 according to FIG. 16. If there is only one step and there is no depression, the ramps of FIGS. 13 and 16 can be combined with one another, as shown in FIG. 17, or the ramps according to FIGS. 13 and 14, ie the longer version If the floor at one end of the threshold already merges into a vertical section, the connecting parts according to Figures 18 and 19 can be used as the second ramps If there is no step, use the ramp according to Figure 13. The ramps of the other exemplary embodiments can also be used in the various g use named thresholds.

Starting from an always constant base profile 1 and a variation of different ramps 2, 2 'which can be connected to this base profile, a set is created for a threshold S which is designed differently and which can even be designed according to the conditions of the building on site. This modular structure is not only extremely useful on the construction site, but also enables the thresholds to be manufactured cost-effectively.

The threshold according to the invention preferably consists of no further parts. It is therefore relatively simple and can be assembled quickly and easily. It is particularly suitable for renovation buildings because it does not require any recesses in the building floor and, in preferred embodiments, can also compensate for varying floor levels.
