EP3130739B1 - Auxiliary device to reducing the barrier effect of a sleeper - Google Patents

Description

The invention relates to a threshold with an additional device for reducing the barrier effect of the threshold, wherein the threshold building inside a horizontally extending cover profile and building exterior comprises a building exterior inclined and / or sloping threshold weatherboard.

Technical area

For both public buildings and barrier-free housing, relevant standards require that lower door stops and threshold levels be either completely avoided or that threshold levels, if unavoidable, be max. 2 cm. At the same time, it is demanded that penetration of moisture in the threshold area is reliably prevented even in heavy driving rain. Currently, a level of up to 2 cm is technically unavoidable as soon as driving rain has to be expected. Constructions that have no or even lower levels - so-called zero thresholds - are therefore generally special constructions that require a considerable amount of extra work.

State of the art

From the WO 2015/011092 A1 is a typical threshold system known that already meets the requirement for a less than 2 cm high level. The threshold used here consists essentially of three components, namely an extruded base plastic body, a cover profile latched thereto, which forms on the inside of the room at the same time the stop edge for the inner stop seal of the inwardly opening door leaf, and an outwardly sloping threshold weather legs made of extruded aluminum, which has a vortex channel on the interior side. The vortex channel is necessary to drain rainwater, which is pushed up in the case of driving rain on the sill weatherstrip, laterally. Due to the system, however, this spinal canal also forms a step and thus represents a certain barrier.

From the EP 1 932 997 A2 a similar sleeper construction is known in which, however, instead of a spinal canal a partially covered step between the outwardly sloping threshold weatherstrip and the inside cover to provide the necessary watertightness.

From the DE 20 2012 001 124 U1 is a barrier-free threshold construction that meets the requirements of a zero threshold, known in the building outside of the actual threshold, a large-volume, parallel to the longitudinal extent of the threshold extending complementary element is provided, which forms a rainwater collection channel, the discharge of rainwater in parallel allows for the longitudinal extension of the threshold. Upwards or to the ground level, this rainwater collection channel is covered by a grate in order to allow the passage of rainwater into the rainwater collection channel. Such a construction is obviously very expensive and only partially used in conjunction with conventional sleepers. In addition, the effect of water drainage is limited, since rainwater, which impinges on the area between the grate and the door, is derived only conditionally, so that the rain-tightness of this construction is limited.

From the FR 3 003 595 A1 is a threshold construction for a disabled access to a building known in which an obliquely outwardly extending body of concrete is covered with a flat grid. The FR 3 003 595 A1 discloses all the features of the preamble of claim 1. Such constructions are on the one hand very expensive to manufacture and very limited in use, since for each door width an individual threshold must be made. Usual thresholds of extruded aluminum and / or extruded plastic are not usable for this construction.

task

Object of the present invention is therefore to provide a threshold or a door with threshold available, both in terms of driving rain tightness and accessibility meet higher requirements and yet associated with limited effort in the production and application.

Presentation of the invention

The invention solves this problem by a known conventional threshold with an additional device for reducing the barrier effect of claim 1, preferably in conjunction with one or more of the features of claims 2 and 3, or by a door according to claim 4, preferably with a or more of the features of claims 5 and 6.

The invention is therefore based on a commercial threshold, as for example from the WO 2015/011092 A1 or the EP 1 932 997 A2 is known, in which thus building inside a horizontally extending cover and building outside a building exterior inclined and / or sloping threshold weather legs is used, wherein between the threshold weather leg and the cover a step, in particular a vertebral channel is formed.

This basic threshold is available by the meter and can be cut to the required length if required.

The additional device used according to the invention comprises a threshold grille and means for spaced attachment of the threshold grate above the sill weatherstrip, so that the threshold grate in the assembled state with its top at least largely in the plane of the horizontally extending cover profile of the threshold used and between the threshold grille and the threshold -Wetterschenkel a water drainage channel is formed. The additional device used according to the invention further comprises a building exterior side extending in the longitudinal extension of the threshold outer cover profile, which extends in the mounted state at least largely with its surface in the same plane as the building inside cover profile and the threshold grating.

Since the threshold grid used thus in the same plane as the top of the commercial threshold used runs, is an absolutely barrier-free, so-called zero threshold possible.

The cover profile of the threshold used need not necessarily represent a separate component, but it may also be integrally connected to the threshold base body and / or the threshold weatherboard. It is only essential to the invention that this area of the threshold used defines a plane which is continued by the threshold grate used according to the invention and the adjoining outer cover profile in the direction of the building exterior.

Since the threshold grille - viewed in the vertical direction - runs above the threshold weather leg of the threshold used, it is at least partially covered by the door leaf or a usually on the outside of the door in the lower horizontal area superior door leaf weatherstrip with the door closed, so that a large part the impending driving rain is already discharged in the outer region of the threshold grate into the water drainage channel. The part of the threshold grille facing the building serves to catch remaining amounts of water before they reach the sealing area between the door leaf and the threshold, which may be wider.

According to a preferred embodiment of the invention are used as a means for spaced attachment of the threshold grate above the sill weatherstrip a plurality of longitudinally extending the threshold spaced from each other arranged bearing adapter, so that between each two storage adapters drainage slots are formed by the water drainage channel to the building exterior. The collected in the water drainage channel rainwater flows in this preferred embodiment of the invention thus not in the direction of extension of the threshold, but transversely thereto in the direction of the building interior to the building exterior.

The bearing adapters advantageously have a shape on their underside which permits easy attachment to the building exterior edge of the sill weatherstrip Threshold allow and on its upper side a support surface for supporting the threshold grille. For various commercial thresholds, therefore, one needed only a possibly uniform threshold grating and one each adapted to the threshold bearing adapter.

It when the additional device according to the invention is used together with a door, which has at least one, preferably several extending in the longitudinal extent of the threshold seals on its underside, of which at least one seal in the closed state of the door rests on the threshold grid used in the invention and this divides into a building inside and a building outside part. The seals used can - as known from the prior art - for example, brush seals, hose seals or lowerable seals, such as magnetically actuated seals, or even a combination of such seals with each other and / or with e.g. be an additional inner stop seal. As far as - as explained above - at least one of the seals used on the threshold grate - especially in the middle area - rests, is reliably achieved that even with very strong driving rain stress already the vast majority of the driving rain in the building exterior side of the threshold grate directed into the underlying water drainage channel and only water that overcomes the barrier formed by the outer seal, must be derived in the building interior region of the threshold grate in the underlying water drainage channel. This achieves an outstanding watertightness.

According to a particularly preferred embodiment of the invention are two provided on the underside of the door used, running parallel to each other in the longitudinal direction of seals on the threshold grate, with the door closed in the threshold grille between the two overlapping seals provided a series of openings in the threshold grate is, so that in this area penetrating water is discharged into the underlying water drainage channel.

Preferably, the threshold grate used in accordance with the invention may preferably be raised when the door is open, and the underlying water drainage channel can be easily cleaned, unless it is additionally screwed on.

According to a preferred embodiment of the invention, the threshold grate used according to the invention has a short angled leg on its longitudinal edge on the building side, with which the threshold grate rests directly on the threshold weather stripe. The threshold grate is preferably made of metal, in particular of aluminum or particularly preferably made of stainless steel, wherein the openings, in particular in the form of two or more rows of transversely extending to the longitudinal extent slots can be produced by punching.

Although in the following embodiment of the invention, an inside opening door is used, the present invention is by no means limited to interior opening doors, but can also be used in outward opening doors.

Best way to carry out the invention

In the embodiment of the invention described in more detail below is a commercially available thermally insulated, from the WO 2015/011092 A1 known standard threshold 1, consisting of a plastic extruded base body 2, also called extruded plastic cover 3, also called the threshold cover, and a sloping at an angle to the building exterior 13 sloping, extruded aluminum sill weathershed 4 used. On the building inside (in Fig. 1 left) side, the threshold weather leg 4 a vertebral canal 18 as a step 23, which would constitute a certain barrier without the additional device according to the invention. Below the standard threshold 1 a Bodeneinstandsprofil 8 can be seen ( Fig. 2 ), which rests on the actual structure, such as a concrete slab.

The additional device according to the invention according to the illustrated embodiment initially comprises a plurality of bearing adapter 5, which - as in Fig. 2 shown - mounted at a distance of about 50-100 mm to each other on the building outside edge of the sill weatherstrip 4 by means of the screws 9. Rainwater that has penetrated into the water drainage channel 19 can therefore flow away in the direction of the arrows 20 between every 2 of these bearing adapters 5. The water supply is in Fig. 7 again clarified.

Outside the building, the outer cover profile 6, which extends over the entire longitudinal extent of the threshold weather leg 4, snapped onto the bearing adapter 5. The top of this outer cover profile 6 runs in the same plane "E" ( Fig. 4 ) As the top of the cover 3 on the building inside 14 of the thermally separated standard threshold 1. Both the outer cover 6 and the inner cover 3 have a corrugated structure to increase the slip resistance.

As in FIGS. 5 and 6 shown, the threshold grille 7 is placed on the weatherboard 11 and building exterior on the bearing adapter 5. For this purpose, the threshold grate building on the inside a fold (s. Fig. 4 in section), so that the threshold grid also runs flush with its upper side in the same plane "E", which is formed by the upper sides of the inner cover profile 3 and the outer cover profile 6 ( Fig. 4 ).

In particular with reference to the cross-sectional view in FIG Fig. 1 It is clear that the space formed between the threshold grille 7 and the obliquely outwardly inclined threshold weather strip 4 forms a water drainage channel 19.

In the illustrated embodiment, the threshold grille 7 is made of stainless steel and has two rows of apertures 22 designed as slots. Between the two rows of apertures 22 extending in the longitudinal direction of the threshold extension narrow web is formed, on which the door is closed, which also extends over the entire extension of the threshold 1 extending tube seals 21. As a result, the threshold grille 7 is divided into a building inside and a building exterior area, so that rainwater, which is pressed for example by gusty wind from the building exterior 13 on the sleeper construction, for the most part already in the building exterior side row of openings 22 in the between the Emerging grate 7 and the threshold weather strip 4 extending water drainage channel 19 is derived. As far as a few drops of rainwater overcome the outer tube seal 21, they are reliably derived in the building inside second row of openings 22 in this water drainage channel 19.

In addition, a further hose seal approximately in the transition region between the threshold weather leg 4 and the cover 3 and the room interior side an inner stop seal 12 is used (s. Fig. 4 ). Laterally, the seal by a known wind stop seal 16 (FIG. FIGS. 5 and 6 ) completes.

As in Fig. 4 shown, in the illustrated embodiment, the floor level 17 runs on the building exterior 13 and the building interior side 14 approximately on the same, formed by the inner cover 3, the outer cover 6 and the threshold grid 7 level "E". Insofar as an inner stop seal 12 is dispensed with, it is also possible to achieve an absolutely level installation.

As in 3 and 4 shown, a weatherboard 11 is provided at the lower horizontal spar of the door leaf 10 on the outside thereof, which covers the threshold grille 7 largely closed with the door closed, so that leaves and snow, the openings 22 of the threshold grid 7 can not clog so easily.

The proposed combination of standard threshold 1 and the additional device allows the production of a so-called zero threshold with excellent watertightness. Since the threshold 1 can be used as a standard threshold without the additional device, the manufacturing and storage costs are reduced considerably.
