EP2610424B1 - Threshold for a lifting/sliding door - Google Patents

Description

The invention relates to a lifting / sliding door with a frame and a sash, wherein the frame has a lower horizontal frame profile, which forms a threshold, wherein the threshold has a profile body having a first profile section and an adjoining second profile section in cross-section, wherein a running rail for a lifting / sliding door is further arranged in the second profile section, which subdivides a surface of the second profile section into two partial areas and which projects in the vertical direction over the profile body.

Threshold profiles for lifting / sliding doors are already known from the prior art. For example, this describes EP 2 105 568 A2 a threshold for building doors with a threshold profile, with at least one formed on a threshold profile top in the region of a closing plane of the building door step-like projection, which adjoins a threshold profile outside a simsartiger area of the threshold profile top, with an additional profile is fastened to the top of the threshold profile, that With its upper side facing away from the threshold profile, it forms a passable and / or walkable surface which merges steplessly or substantially steplessly into the upper side of the projection. It is thus a barrier-friendly training of the threshold allows using conventional threshold profiles.

The EP 2 202 378 A2 describes a threshold for a lifting sliding window or a window door, consisting of a base profile and an outer edge superior extension profile, both the base profile and the extension profile are inclined to an outside downwards, and the extension profile to a pre-assembled or vorzumontierendes base profile without additional connecting means can be retrofitted to form the threshold. By this construction, on the one hand, the outer construction is made possible on the extension profile, on the other hand, this extension profile is used to push open roller shutter guides and for receiving water-repellent geomembranes.

From the EP 1 057 961 A2 is a threshold profile for building doors with the features of the preamble of claim 1, in particular lifting sliding doors, known, which is made of plastic, in one piece with a reinforcement to increase the carrying capacity having inner profile section, with a likewise a gain to increase the carrying capacity having outer profile section and with a the inner and the outer profile section connecting middle profile section. It is thus provided a threshold profile that has a high robustness and load capacity and improved thermal insulation.

The EP 2 228 511 A2 describes a threshold profile for at least one lifting sliding door, at least comprising a plurality of individual profiles made of plastic and / or metal, in which the individual profiles are connected to a threshold profile, wherein the individual profiles are closed and arranged side by side and on the individual profiles mutually corresponding connecting means are provided connect the individual profiles with each other, wherein the locking of at least some connection means via locking profiles. Through this multi-part construction of the threshold profile, a better thermal protection is achieved.

The present invention has for its object to provide a threshold for a lifting / sliding door, with the improved waterproofness of the lifting / sliding door is made possible.

This object of the invention is achieved with the above-mentioned lifting / sliding door, in which the two partial areas of the surface of the second profile section of the profile body are formed against the horizontal and inclined to each other, wherein the first portion with a downward slope in the direction of the first profile section and the second portion is formed with a downward slope toward the rear end surface of the profile body, and wherein the second portion extends to a vertical rear end surface of the profile body. Due to the inclination of the two partial surfaces left and right (viewed in cross section) of the running rail for the lifting / sliding door, a better centering of the door leaf of the lifting / sliding door is achieved when closing, whereby the built-in sealing levels can be brought to rest more precisely to the mating profile, so the water and wind tightness can be improved. In addition, but also a better drainage per se is achieved, since in the area of the closed door the water does not stop can, but drains off. It is thus a flatter training of the threshold possible because drainage on a so-called water sump in the threshold, as he eg from the DE 10 2006 007742 A1 is known, can be dispensed with. Due to the flatter construction, the threshold is again handicapped accessible ausbildbar.

Preferably, the two sections are formed opposite each other inclined, since thus the centering function can be better realized.

According to a further preferred embodiment, the second profile section of the profile body has a horizontal length which at least approximately corresponds to a cross-sectional width of the sash frame. In other words, therefore, the second profile section is at least approximately covered by the door, whereby the waterproofness in this area can be further improved, and in particular the running rail or the wheels of the lifting / sliding door can be better protected from moisture, thereby noise through Squeaking noises can be better prevented.

But it is also possible that a contour of the lower, pointing to the ground sill wing frame profile is at least approximately opposite to the contour of the sash profile of the second profile section. Again, so that the water and windproofness are improved by the seals of the sash profile fit better against the threshold. It also better supports the centering function.

After the second profile section can partially project beyond the first profile section of the profile body of the threshold in the vertical direction, and thus the outside air can be partially exposed directly, the threshold is preferably formed as a hollow chamber profile with at least two hollow chambers, wherein the two hollow chambers are separated by a web , It is thus achieved a better thermal insulation in the area of the threshold.

According to a preferred embodiment variant, the web is arranged below the running rail. It can thus be achieved by the load transfer over the web, a support function for the running rail, whereby the wall thickness of the profile body of the threshold can be reduced. As a result, this in turn can be achieved better thermal insulation.

To further improve the removal of water can be provided that the pointing to the door surface of the first profile section of the profile body is also formed inclined to the horizontal, i. with a slope to the outside. It can thus be achieved in this level drainage, whereby the profile cross-section height can be further reduced.

The profile body may in particular be integrally formed. By avoiding connection areas between the individual profile sections, the profile cross-section can be made shallower, i. be formed with a lower component height, since no weakening zones are present over the profile cross-section. It is thus the disabled-accessible design of the threshold further improved.

According to another embodiment, it is provided that an end region of the partial region of the second profile section of the profile body extending in the direction of the first profile section has at least one connection region for a further profile element. This connection region may be formed, for example, as a simple longitudinal groove. It can be achieved that, if necessary, e.g. in the field of fixed glazing a lifting / sliding door, on the threshold just more profile elements can be arranged to horizontal, i. horizontal to form surface areas.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

The Fig. 1 shows a variant of a lifting / sliding door 1. This has a door 2 and a fixed glazing 3, ie a fixed glass element, as is known per se. Such lifting / sliding doors 1 are used for example in conservatories or in the area of terraces and balconies. Of course, other uses are given. But it is also possible that the lifting / sliding door 1 has a plurality of door leaves 2 and / or no fixed glazing 3.

The lifting / sliding door 1 has a frame 4, which is fastened for example in a wall opening. The frame 4 comprises a lower horizontal frame profile 5.

The door leaf 2 has a door leaf frame 6, which comprises a plurality of door leaf frame profiles 7, of which in particular a glass element 8 is held.

The frame 2 and / or the door leaf frame 6 may be made of wood and / or plastic and / or a metallic material.

Fig. 2 shows a detail of the lifting / sliding door 1 in the region of a lower guide 9 in cross section. The guide 9 may be formed as a sliding or roller guide or the prior art for lifting / sliding doors 1 accordingly.

The frame 4 includes the bottom horizontal frame profile 5. This frame profile 5 forms a bottom threshold 10. The bottom threshold 10 has a profile body 11 which, viewed in cross section, has a first profile section 12 with a width 13 and a second profile section 14 with a width 15 adjoining thereto having. In the illustrated embodiment of the threshold 10, the second profile section 14 adjoins directly to the first profile section 12, so that therefore the sum of the two widths 13, 15 results in the entire profile width of the threshold (viewed in cross section). However, there is also the possibility that at least one further profile section is arranged or formed between these two profile sections 12, 14.

The second profile section 14 has a longitudinal groove 16, in which a running rail 17 for the lifting / sliding door 1 is arranged or attached. For this purpose, the longitudinal groove 16 on the side walls in each case at least one, inwardly over the respective side wall projecting locking lug 18, 19 have, for example in the form of longitudinal webs. The running rail 17 can accordingly have two downwardly projecting profile limbs 20, 21, whose ends have a latching means, for example an at least approximately L-shaped cross section. Of course, the running rail 17 but also be secured elsewhere in or on the longitudinal groove 16, for example by means of screws or by gluing.

Furthermore, it should be noted that the running rail 17 and a different than in Fig. 2 may have shown cross-section.

The running rail 13 may for example consist of a metallic material or plastic.

The rail 13 divides a surface 22 of the second profile section 15 into two subregions 23, 24. The subregion 23 is facing the first profile section 12, while the subregion 24 faces a rear, chamber-side end surface 25 of the bottom sill 10. In addition, the track 13 projects vertically Direction over the profile body 11 of the threshold 10 and forms the highest point of the threshold. 10

The running rail 13 may have at the top a particular rounded guide web 26 for an impeller 27 of the lifting / sliding door 1, as is known in principle from the prior art.

Next, the running rail 13 preferably adjacent to the guide web 26 arranged wing-like projections 28, 29 which cover the longitudinal groove 16 of the bottom threshold 10 or cover.

In principle, a plurality of rails 17 can be arranged next to one another or the rail 17 can have two or more guide webs 26, in particular if the lifting / sliding door 1 more than a liftable and sliding door 2 has.

How out Fig. 2 can be seen, the two portions 23, 24 of the surface 22 of the second profile section 14 of the profile body 11 against the horizontal and inclined to each other, wherein the rear portion 24 extends to the vertical rear end face 25 of the profile body 11.

An angle of inclination 30 of the front portion 23 may be selected from a range of 7 ° to 18 °, in particular from a range of 9 ° to 13 °.

An inclination angle 31 of the rear portion 24 may also be selected from a range of 7 ° to 18 °, in particular from a range of 9 ° to 13 °.

The two subregions 23, 24 may have a mutually different angle of inclination 30, 31, in which case it is preferred if the second, rear subregion 24 runs flatter than the first, front subregion 23. In the preferred embodiment, the two subregions 23 , 24 thus formed inclined in the opposite direction, that is to say with the same inclination angles 30, 31 with respect to the absolute value. The second profile section 14 thus has an at least approximately saddle-roof-shaped appearance.

On the door leaf frame 6 and / or optionally on the frame 4, at least one seal 32, 33 can be arranged or formed from the usual elastomeric materials. The representation in Fig. 2 is not meant to be limiting in this regard. In particular, these seals 32, 33 are formed in the region adjacent to the running rail 17 in a groove on the underside of the lower door leaf frame profile 7 and extending in the direction of the bottom sill 10, wherein the seals 32, 33 may have a sealing lip, respectively extend in the direction of the running rail 17, so as to improve the water and wind resistance in this area. But there are also other sealing arrangements, as they are known for example from the prior art, possible. The seals are in particular after the lowering of the door leaf 2 when closing the lifting / sliding door 1 on the bottom threshold 2.

It is also possible that 6 metallic attachment shells 34 are arranged or fixed to the frame 4 and / or on the door frame, for example, made of aluminum or an aluminum alloy.

In addition, 6 thermally insulated profile elements can be used for the frame 4 and / or the door leaf frame, for example, at least partially filled with a foam hollow chamber profiles made of plastic. The thermal insulation may optionally also be arranged between the profile elements and the attachment shells 34.

Preferably, the width 15 of the second profile section 14 of the threshold 10 is dimensioned so that the lower door leaf frame profile 7, this profile section 14 at least approximately - viewed in the vertical direction - covers. In other words, therefore, a cross-sectional width 35 of the door leaf frame 6 in the horizontal direction is at least approximately as large as the width 15 of the second profile section 14.

At the in Fig. 2 illustrated variant of the lifting / sliding door 1 is a contour of the lower, pointing to the threshold 10 door leaf frame profile 7 at least approximately opposite to the direction of this door frame profile 7 facing contour of the second profile section 14 of the bottom threshold is formed, thus, for example, in cross section at least approximately an inverse saddle-roof-shaped contour. So there are lower side edges 36, 37 of the lower door leaf frame profile 7 located lower than a central region 38 of this door leaf frame profile 7, in which the running rail 17 is applied when the lifting / sliding door 1 is closed.

In principle, however, other contours of this lower surface of the door leaf frame profile 7 are possible, for example, a stepped, etc., although the at least approximate inverse replica of the contour of the second profile section 14 in this area of facing surfaces of the bottom threshold 10 and the lower door leaf frame profile 7 in With regard to the wind and water resistance has advantages.

In the preferred embodiment, the profile body 11 of the bottom sill 10 is formed as a hollow chamber profile with at least two hollow chambers 39, 40, in particular in the second profile section 14, which are separated by a vertically extending web 41. Of course, more than two separate hollow chambers 39, 40 may be formed in the bottom sill 10, for example four, as in Fig. 2 is shown.

This web 41 is preferably arranged below the running rail 17 in order to allow a better load transfer.

The first profile section 12 of the bump 10, i. its surface, may also be formed inclined to the horizontal, so that therefore the threshold 10 is continuously formed inclined in the region of the upper surface. To form horizontal surfaces, for example, in the area below the fixed glazing 3, so that it has a flat contact surface, further profile elements 42, 43 may be arranged, which are wedge-shaped on the underside and thus preferably large or full surface on the chamfered first profile section 12th the bottom threshold 10 rest. These profile elements 42, 43 do not extend into the region of the closed door leaf 2, i. they are preferably arranged exclusively in the area of the fixed glazing on the threshold, so that in the outer region of the closed door leaf 2, the drainage over the inclined planes of the threshold is not interrupted by these further profile elements 42, 43.

For better connection of the further profile elements, recesses 44, 45 can be provided in the first and / or in the second profile section 12, 14 of the threshold, into which correspondingly positioned extensions 46, 47 of the respective profile element 42, 43 engage. Of course, in each case more than one recess 44 or 45 and more than a projection 46 or 47 per further profile element 42, 43 are provided, whereby a positive and / or frictional connection of the further profile elements 42, 43 to the bottom threshold 10 are possible.

The further profile elements 42, 43 are preferably each formed in one piece and preferably formed from the material of the bottom threshold 10, for example made of plastic, but may also consist of a different material. Further, the profile elements 42, 43 may be formed as hollow chamber profiles or as solid material element.

Likewise, the profile body 11 of the threshold 10 is preferably formed as one piece, as shown, for example, as an extruded profile. In principle, however, a multi-part design is possible, for example by the individual profile sections 12, 14 each consist of a separate component.

The threshold 10 has in the in Fig. 2 shown construction or may generally have a maximum height in the vertical direction of about 3 cm, in general, the threshold may have a maximum height of up to 4.5 cm. The maximum height is in the region of the running rail 17 - wherein the running rail 17 is not part of the profile body 11 of the bottom sill 10 - is formed, as is made Fig. 2 is apparent.

To reduce this maximum height to, for example, a maximum of about 2 cm, as can the embodiment of the lifting / sliding door 1 after Fig. 3 shows, in the region of a front end face 48 of the threshold 10, a further profile element 49 are arranged. This further profile element 49, which in turn may be formed from a plastic or a metallic material, has a U-shaped cross-section for forming a drainage channel.

In order to allow the drainage in this further profile element 49, this is connected in accordance with the threshold 10, so that thus from the bottom threshold 10 running water can flow into the drainage channel. For this purpose, at least one connection region for the further profile element 49 may be provided in an end region of the first profile section 12, in particular in the front end surface 48 of the bottom sleeper 10, ie that end surface 48 which faces the outside atmosphere. This connection area is formed in particular by an undercut longitudinal groove 50, in which a latching element, in particular a latching hook 51 latchingly engages, so that the connection can be stopped by simply plugging. The latching hook 51 is to be formed on an angled leg 52 of the further profile element 49, wherein the leg 52 is designed to extend in the direction of the threshold, so that therefore the further profile element 49 exclusively via the latching hook 51 and the legs 52 at the bottom threshold 10th is present, but otherwise objected to this is arranged.

Of course, another embodiment of the connection of the further profile element 49 to the bottom threshold 10 is possible, for example by gluing the two components together, but the above-described connection has the advantage of easy mounting on the site via the latch.

In both variants of the lifting / sliding door 1 after the Fig. 1 and 2 the threshold is arranged on a building connection element 53, which is inserted before the installation of the lifting / sliding door 1 in the designated wall opening. The construction connection element 53 is preferably also formed from a hollow-chamber profile or a plurality of hollow-chamber profiles 54, 55, which are in particular made of plastic, and which are preferably thermally separated from each other via a thermal insulation element 56. The heat-insulating element, in particular a rigid polyurethane foam, may optionally be adhesively bonded to the two adjacent hollow-chamber profiles 54, 55.

In principle, it is also possible to arrange a plurality of thermal insulation elements 56, in which case the construction connection element has more than two hollow chamber profiles 54, 55 or the thermal insulation element 56 is arranged in one of the hollow chambers of the hollow chamber profiles 54, 55.

The connection of the hollow-chamber profiles 54, 55 of the construction connection element 53 with the bottom threshold 10 can also via latching element 57, such as latching hooks, as shown in the Fig. 2 and 3 is shown, or via another connection technique, for example by gluing done. In addition, sealing elements 58 made of an elastomeric material can be provided to increase the water and wind tightness, between the hollow chamber profiles 54, 55 of the structural connection element 53 and the threshold 10 extend. The sealing element 58 may be fastened to the hollow-chamber profiles 54, 55 or to the underside of the threshold 10.

To increase the watertightness in the region of the structural connection element 53, this may be preceded by a further profile element 59 in the direction of the outer region. This profile element 59 may be, for example, a profiled sheet with at least approximately L-shaped cross-section, wherein the preferably perpendicular protruding lower leg - it is also possible from the perpendicularity variants possible - of the construction connection element 53 points away.

This further profile element 59 is preferably connected to the bottom threshold 10, in particular hooked in a further (undercut) groove-shaped recess 60 in the end face 48. For this purpose, the further profile element 59 in the upper end region have a connecting element 61, which allows the suspension with a pivoting movement of the profile element 59.

The further profile element 59 is preferably dimensioned in its vertical dimension, which extends to a lower contact surface 62 of the structural connection element 53.

How out Fig. 3 can be seen, the drainage channel forming profile element 49 may be disposed on a construction connection element 62, which is preferably also made as a hollow chamber profile of a plastic. The connection of the profile element 49 to this construction connection element 62 can take place in the same manner as has been described for the construction connection element 53 below the floor threshold 10. In this case, at least one sealing element 63 can also be arranged between the further construction connection element 62 and the profile element 49.

The drainage channel can also be covered with a covering element 64, for example a grate. This cover member 64 may e.g. be plate-shaped or formed as a profile with a C-shaped cross-section.

If the threshold 10 is made of a plastic, this preferably has no metal stiffening.

In the preferred embodiment of the threshold 10, the profile body 11 is formed from a fiber-reinforced plastic, in particular from a fiber-reinforced polyurethane. The fiber content may be between 40% by weight and 80% by weight, in particular between 50% by weight and 70% by weight, in particular 60% by weight. The remainder to 100 wt .-% forms each of the polymeric plastic, so for example, the polyurethane.

The fibers for fiber reinforcement may be selected from a group comprising glass fibers, basalt fibers, or natural fibers. The fibers may further have a fiber length between 10 mm and 50 mm, in particular between 20 mm and 40 mm.

According to a further embodiment of the threshold is provided, as in the Fig. 2 and 3 is shown that in the first profile section in the region of the front end face 48, a recess 65 is arranged or formed, in which a glass strip 66 is arranged for holding the fixed glazing 3, wherein the glass strip at least 50% below that point of the profile body 11 of Threshold 10 is arranged, which - viewed in the vertical direction - the largest height of the profile body 11 has. In accordance with the above explanations, this highest point is formed around the area next to the running rail 17 in the profiled body 11. This deep arrangement of the glass strip 66 in turn allows a formation of the threshold 10 with low component height, so that they can be made more accessible.

In the preferred embodiment, the recess 65 is formed on an upwardly facing surface 67 of the first profile section 12 of the threshold.

Viewed in cross-section, the glass strip 66 preferably has a base profile 68 with an approximately U-shaped cross section, which has a base 69 and two legs 70, 71 projecting therefrom. The two legs 70, 71 may have a mutually different length, as shown in the Fig. 2 and 3 is apparent.

In at least approximately vertical direction, a retaining leg 72, preferably extending at least approximately at right angles to the base 69, is formed on the base 69. The holding leg 72 has, in an end region 73, a sealing element 74 made of an elastomeric material, which is connected to the holding leg 72 and this in the horizontal direction and protrudes in the direction of the glass element of the fixed glazing 3. With this sealing element 74 of the holding leg 72 is applied to the glass element. In addition, the glass element can be glued to the holding leg 72 in a connecting region 75, as is known in principle from the prior art. The adhesives used for this purpose are also known from the prior art.

In addition, it should be pointed out that the glass element can be connected to the frame of the fixed glazing via additional gluing areas 75 ', 75 ", 75"', as is also customary in the prior art. Reference is made to the relevant literature.

At the leg of the base 10 closer leg 71 of the base profile, a connecting leg 76 is arranged, which engages in the recess 65 of the threshold, in particular latching. In order to facilitate the insertion of the connecting leg 76 into the recess 65, an end portion 77 of the connecting leg 76 is angled, as shown in FIGS Fig. 2 and 3 is apparent.

Furthermore, the connecting leg 76 has a downwardly projecting holding web 78, which abuts with a side wall on a side wall of the recess 65 and thus together with the end portion 77 forms a clamping of the connecting leg 76.

The glass strip 66 rests on the connecting leg 76 on its underside on a, in particular horizontal, adjoining the recess 65 end face 79 of the threshold. Preferably, this support is at least partially formed below the leg 71 of the base profile 68.

In principle, the glass strip 66 may also have a different cross section. For example, can be dispensed with the outer leg 70 of the base profile 68, but on the one hand this increases the stability and on the other hand, thus a better waterproofness of the connecting portion with the bottom threshold 10 is achieved. It could, for example, the glass strip 66 may be formed so that the leg 71 passes directly into the holding leg 72.

For the sake of completeness, it should be pointed out that the floor sill 10 extends at least from one vertical frame profile 80 to another vertical frame profile 81 (FIG. Fig. 1 ) of the frame 4 extends continuously.

The embodiments show possible embodiments of the lifting / sliding door 1 and the bottom threshold 10, with various combinations of the individual embodiments are mutually possible and this variation possibility due to the doctrine for technical action by objective invention in the skill of those working in this technical field.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the lifting / sliding door 1 or the threshold 10, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size. <B> Reference Numbers </ b> 1 Lifting / sliding 36 side edge 2 door 37 side edge 3 fixed glazing 38 mid-range 4 frame 39 hollow 5 Frame profile 40 hollow 6 Door sash 41 web 7 Door sash profile 42 profile element 8th glass element 43 profile element 9 guide 44 recess 10 speed bump 45 recess 11 profile body 46 extension 12 profile section 47 extension 13 width 48 face 14 profile section 49 profile element 15 width 50 longitudinal groove 16 longitudinal groove 51 latch hook 17 runner 52 leg 18 locking lug 53 Bauanschlusselement 19 locking lug 54 Hollow chamber profile 20 profile leg 55 Hollow chamber profile 21 profile leg 56 thermal insulation element 22 surface 57 locking element 23 subregion 58 sealing element 24 subregion 59 profile element 25 face 60 recess 26 guide web 61 connecting element 27 Wheel 62 Bauanschlusselement 28 extension 63 sealing element 29 extension 64 cover 30 tilt angle 65 recess 31 tilt angle 66 glazing bead 32 poetry 67 surface 33 poetry 68 basic profile 34 Intent shell 69 Base 35 Section width 70 leg 71 leg 72 holding leg 73 end 74 sealing element 75 connecting area 75 ' adhesive area 75 " adhesive area 75 ''' adhesive area 76 connecting leg 77 end 78 holding web 79 face 80 frame profile 81 frame profile
