Description

The invention relates to a door sill system for a front door, a tilt-turn door or the like., With a door frame with threshold and at least one revolving door sash.

The threshold of a door arrangement represents both a sensitive and critical area of the building closure. On the one hand, the threshold should be as barrier-free as possible and therefore provide a low crossing height. On the other hand, the penetration of driving rain etc. must be reliably prevented.

So is out of the DE 20 2014 102 797 U1 a door sill system for a front door, a shop door or the like with a door frame with threshold and at least one revolving door wing has become known, which is designed almost completely barrier-free. For this purpose, an adapter profile is mounted on the bottom-side stepped rabbet of the revolving door leaf, which leaves a narrow, but over the entire thickness of the door leaf passing gap between the bottom of the revolving door leaf and the threshold. This gap is also sealed by means of a lowerable sealing strip and / or brush seal.

With such a construction can be achieved in fact a high degree of accessibility in the threshold area. On the other hand, however, such a construction is not suitable for producing a reliable impact rain protection. The mounted on the underside of the adapter profile sealing elements are not sufficient in practice to create a reliable building closure. It does not change anything that a grid is arranged on the outside in the entrance area, via which moisture can be discharged to the outside. This known construction is thus particularly suitable for doors in the interior or in covered spaces such as shopping malls or the like.

In contrast, a more or less suitable impact protection is usually achieved in conventional door sill systems in that obliquely rising profiles with undercuts provide protection against entering fluid. Even under wind loads, the moisture would then have to be driven up against its gravitational force and remain attached to undercutting edges, etc. This effect is further enhanced by the fact that the threshold increases above the outside floor so that no additional moisture reaches the threshold from the outside. This achieves useful building protection. Then in the direction of the inside, then usually two sealing levels still make a thermal decoupling to the door.

A disadvantage of these constructions, however, is that in extreme wind conditions, etc., nonetheless, liquids may enter. The gradually rising profiles in the threshold area can then restrain the water masses only inadequately.

Another disadvantage is that thus results in a relatively large structure in the threshold range to provide a sufficient droop. Thus, no low crossing height can be achieved. Exceeding such a threshold is thus not without problems.

The invention is therefore based on the object, a door sill system of the generic type such that its construction height can be reduced and a particularly good power rain protection is achieved.

This object is achieved by a door sill system having the features of claim 1. This is characterized in particular by the fact that the bottom threshold contains a base body, wherein the revolving door has at least one stop rebate, which cooperates with at least one stop on the base body and produces a sealing plane, wherein the base body has a tread area, which provides a tread surface and for water drainage serves to the outside, wherein the tread area is formed in the manner of a grid and at least one Having water collection chamber with a drainage slope in the bottom region, and wherein moisture arrives via an inlet opening in the at least one water collection chamber and drains out of this via outlet openings to the outside.

The door sill system according to the invention thus provides the provision of a sealing plane as a necessary element for a reliable driving rain protection. It has been shown in the context of the invention that only by the interaction of the Anschlagfalzes on revolving door leaf with the stop on the body a safe and lasting sealing effect is achieved.

At the same time, however, the invention also provides for the provision of a grid-like structure of the tread area. This allows a particularly good watertightness of the door sill system. Pending moisture or driving rain are thus not pre-headed towards the interior of the door assembly, but derived between the bars of the tread area. In the at least one water collecting chamber, the moisture is thus captured and prevented from advancing. At the same time a regulated and targeted removal of moisture is achieved through the outlet openings in the water collection chamber.

A further advantage of the present invention resides in the fact that the tread area in the ground sill thus does not have to have an upward structural design in order to provide drainage slopes or undercuts. These elements are laid almost into the interior of the tread area, which significantly reduces the overall height. The tread area can then also run in a plane with the upper edge of the outside pending floor.

This makes it possible to achieve an extremely low crossing height via the door sill system according to the invention, which results in a high degree of user comfort. In particular, barrier-free, i. Accessible access.

Thus, according to the invention, the sealing plane formed by the stop fold or stop and the tread area formed in the manner of a grid also participate Water collecting chamber for dissipating the moisture advantageously combinatorial together to achieve a particularly good driving rain protection at low height.

Advantageous developments of the door sill system according to the invention are the subject of the dependent claims.

Thus, the revolving door has two Anschlagfalze, which produce two seals with stops on the body. In practice, it has been shown that a particularly good impact protection can be achieved. In addition, heat losses via the front door arrangement can be significantly reduced.

These effects are even more effective if a seal is arranged on the at least one stop fold. In this way, a particularly reliable building completion can be achieved at this point.

It is a further advantage if the door sill system further comprises a sealing web which seals the main body to the outside and is fixed on the tread area and / or on the main body of the threshold. Then a total of a particularly reliable sealing of the threshold is achieved, so that the ingress of moisture can be avoided particularly safe. The attachment of the sealing strip at the tread area and / or on the base body of the threshold also makes it possible to permanently and particularly suitable to position the sealing strip.

It has proven to be advantageous in practice, when the sealing web is fixed by a bond at the tread area and / or on the body. The sealing effect then remains undiminished and the installation of the sealing strip can be carried out with simple and proven means.

Furthermore, the tread area can have a plurality of water collecting chambers, which are connected to one another via the outlet openings. The length of the tread area can thus be adapted to local conditions. In particular, it is possible to provide particularly receptive tread areas and water collection chambers when the increased amount of driving rain is expected. This example of door arrangements of the case, which are particularly exposed to the weather.

It has proven in practice, when the outlet openings are formed as boreholes. Then with simple means a reliable water removal can be achieved.

Alternatively, the outlet openings may also be formed through a slot through the water collection chambers. Then, the production of the outlet openings simplifies significantly, since such a slot can be introduced at the bottom of the tread area in one go. In addition, this can be a complete drainage of the water collection chambers achieve while remaining with holes usually production-related edges in the water collection chambers, where a certain amount of water can remain.

Furthermore, it is advantageous if the tread surface of the tread area is aligned substantially horizontally. In this way, its height can be kept very low. Then the ease of use for the door sill system according to the invention further increases.

If the tread is formed of a metal profile, it has a particularly good robustness and durability.

In particular, in the case of doors with a plurality of revolving door wings, it is advantageous if a closing part is also arranged on the base body. Then a reliable locking of the door is possible. Currently, however, the height of the body in the area of the threshold can be kept low.

As shown in Fig. 1 For example, a door sill system 1 has a door frame with a sill 2 and a revolving door sash 3. Shown in the figures is only this lower portion of the door, which is particularly important for the watertightness.

The revolving door leaf 3 is formed in a conventional manner as a wood-aluminum composite profile. As a connecting element between a sash wood 31 and an aluminum panel 32 is a rotary connector 33. The sash also has two Anschlagfalze 34 and 35, which each receive seals 36 and 37 and represent sealing levels for the door assembly.

The ground sill 2 is formed in two parts in this embodiment of a base body 21 and a tread area 22. The main body 21 is made of a wood fiber reinforced plastic (WPC). It also has stops 21a and 21b, which cooperate with the seals 36 and 37 for producing the two sealing levels.

The tread area 22 is formed of an aluminum profile and has a grid-like shape. He is fixed by screwing on the body 21. The tread area 22 includes a tread surface 22a, below which water collection chambers 22b are located. The tread surface 22a is interrupted by inlet openings 22c for moisture etc. The individual water collecting chambers 22b each have outlet openings 22d, via which moisture is discharged to the outside. A bottom 22e of the tread area 22 is formed inclined outwardly for this purpose. The tread surface 22a, however, is aligned substantially horizontally. It is ultimately formed by the L-shaped webs which bound the water collection chambers 22b.

On the outside, the door sill system 1 is adjoined by an arbitrary floor area; in the illustrated embodiment, this is an elevated terrace floor T made of wood. The upper edge of the terrace floor T aligned with the tread surface 22a.

On the inside of the room, a floor F connects to the threshold 2, which must be lower due to the system. In the example shown, its upper edge is lower by a dimension X than the level of the tread surface 22a or the upper edge of the terrace floor T. The dimension X represents the crossing height of the door sill system 1 and has here 20 mm. The door sill system 1 is therefore designed for the disabled.

If there is the danger that moisture will enter the interior through the door sill system 1, be it due to driving rain and / or wind load etc., it will be reliably caught in the water collection chambers 22b of the tread area 22 and discharged outwards therefrom.

How out Fig. 1 Furthermore, it can be seen, the tread portion 22 is further coupled on its underside with a sealing strip 26 which is formed of an elastic, reliable sealing material such as plastic. In the exemplary embodiment shown, one end of the sealing strip 26 engages positively in a groove of the tread area 22 and is thus reliably held thereto. It then runs on the body 21 down to the Floor area where it is deflected to the outside and this also covers sealing. In the example shown, the sealing web 26 then cooperates with a terrace seal with which it is connected watertight (not shown). The water discharged to the outside from the water collecting chambers 22 b is thus reliably kept away from the main body 21.

In the Fig. 2 to 6 modified embodiments of the door sill system 1 are shown. These relate in particular to old building renovation profiles in which existing systems are adapted in accordance with the invention. The revolving door leaf 3 is identical in all variants to that according to Fig. 1 , It is therefore generally not explained separately. Reference is made to the above statements. The difference of these statements to the first embodiment according to Fig. 1 lies in each case in the structure of the threshold.

Thus, the embodiment differs according to Fig. 2 from that in Fig. 1 in that a base body 21 'of a threshold 2 is formed in two parts. A base portion 21c of the main body 21 'comes from the inventory of the building and is used again in the renovation. An attachment 21d, which is fastened thereto in the course of the refurbishment and cooperates with the revolving door leaf 3 in the manner already explained, extends over this. The tread area 22 is also identical to that in FIG Fig. 1 executed.

The embodiment according to Fig. 2 shows that the door sill system 1 can be readily used in the renovation of old buildings.

The variant according to Fig. 3 is different from that in Fig. 2 by the shape of a tread area 22 '. Instead of L-shaped webs here are now 1-shaped webs without a transverse leg at the free end provided to form the water collection chambers 22b '. With this variant, the advantages of the invention can be achieved.

Fig. 4 shows a modification of the embodiment according to Fig. 2 to the effect that additionally a closing part 23 is present on an attachment 21d 'of the main body 21'. This is pushed from the room inside on a pedestal 24 on top 21 d '. The base 24 is screwed to the main body 21 '. Such a closure member 23 is used when the door has a plurality of revolving door wings 3, which require, for example in the central region of the door opening on the bottom side still an anchorage. The closing part 23 is designed as an aluminum profile.

The embodiment according to Fig. 5 based on that of Fig. 4 with the closing part 23 and applies this together with the tread area 22 'of Fig. 3 at. Such a combination is readily usable.

Fig. 6 Finally, there is shown another embodiment in which a tread portion 22 "is modified so as to be held in grooves in a base portion 21c" of a main body 21 "by spring projections 22f Fig. 3 , Furthermore, the tread area 22 "in the region facing the seal 36 of the revolving door leaf 3 has a receiving groove for a sealing element 25. This cooperates directly with the seal 36 for producing a sealing plane modified previous embodiments.

Fig. 7 shows a perspective view of another embodiment of the door sill system according to the invention 1. This differs from the previous embodiments again in the construction of the bump. 2

Unlike the in Fig. 4 a variant 21d '''of a base 21''' designed as a metal profile element and also carries a base 27 for a modified designed tread area 22 ''.

A sealing web 26 'is attached by gluing to a web 27 a of the base 27. The sealing path 26 'extends vertically downwards along the main body 21'", as in the other embodiments, before moving outwards in the bottom area is diverted. The sealing web 26 'may also be secured at suitable locations on the base body 21''' and in the bottom region by gluing to permanently ensure their positioning. In this case, the sealing web 26 'is connected to other sealing webs to produce a reliable seal against moisture on the bottom side as well as in the upright area on the door reveals, etc.

In Fig. 8 is the tread area 22 '''off Fig. 7 shown in more detail. Shown is a bottom view in perspective execution, from which it can be seen that water collection chambers 22b "outlet openings 22d ', which are made by forming a slot transverse to the water collection chambers 22b". For a reliable and complete drainage of the water collection chambers 22b "can be achieved.

The invention allows, in addition to the illustrated embodiments, further design approaches.

Thus, the lattice-like tread region 22 etc. may also be designed so that it has only a single water collection chamber. On the other hand, the number of water collecting chambers can be adjusted according to the local conditions and also differ from the three to five shown.

Furthermore, it is not absolutely necessary for the tread surface 22a of the tread region 22 to be oriented substantially horizontally. These, for example, may be inclined in certain applications, without the operation of the door sill system 1 would be affected. Preferably, the tread 22a would then be provided ascending to the inside of the door, which would also slow down even swelling water etc. even better.

It is not necessary for the tread area 22 etc. to be formed from a metal profile, in particular one with an aluminum profile. Instead, it can also be made of a plastic or wood fiber reinforced plastic.

In particular, it is possible to form the tread area 22, etc. in one piece with the base 27 or the main body 21, etc.

The main body 21, etc. may consist of different materials. In addition to a wood fiber reinforced plastic (WPC), wood, plastic, metal or even a combination of these materials can be used. If the base body is designed as plastic or metal, then this is typically present as a hollow profile body.

The attachment of the tread area 22 etc. and optionally the closing part 23 with the base 24 on the base body 21 is typically carried out by screws. However, it is also possible that snap-in connections, clip closures, adhesive connections or the like are used instead.

The closure member 23 does not have to be pushed from the side onto the base 24; Here, a fixation from above could be used by a latching mechanism or the like.
