EP3653830B1 - Device for covering a sliding wing, folding sliding wing or movable lifting wing of a window or door - Google Patents

Description

The invention relates to a combination of a window or a door with a cover plate and a cover profile which is attached in a special way to the window or the door. The cover plate and the cover profile cover a joint area between two laterally vertical frame spars, also known as frames, a frame to be inserted in a building opening and a lower frame spar, which is also referred to as a threshold, for a sliding sash, folding-sliding sash or sliding lift-and-slide sash of the window or a door according to the preamble of claim 1.

Slidable sashes as sliding sashes, folding-sliding sashes or sliding lift-and-slide sashes of a window or door are known in various designs and, in the simplest case, consist of a sliding sash arranged in an outer frame for opening and closing and a sash, also in the frame arranged further door or window element, for example inactive leaf or fixed field.

The closed sliding sash can be locked on its side facing away from the door or window element by actuating a fitting provided in the sash on the frame and thus secured against unauthorized opening. Horizontally movable sliding sashes are usually slidably received above or below the sliding sash. When opening, usually with an operating handle on lift and slide sashes, the sliding sash with the seals is lifted, which makes it easier to run. The open sliding sash can then be pushed in front of an adjacent inactive sash. Lift-slide sashes can only be pushed or tilted depending on the design. When closing, the sliding sash is lowered and the seals are pressed on again. Opening and closing is also possible via electrical, hydraulic or pneumatic actuators.

A seal in the vertical transition or joint area between the sliding sash and the fixed panel, where the closed sliding sash adjoins the further fixed panel or door or window element, is generally made by means of sealing strips or profile strips with seals that seal in the closed position.

In this joint area, sealing strips or profile strips are known which are attached to a vertical section of the sash and the further door or window element, so that when the sliding sash is closed, the sealing strips overlap in the area of their first profile sections and at the same time engage behind. The closing of gaps between the sliding sash and the inactive sash in the vertical area of the sealing strips is carried out with a view to sealing measures against possible ingress of water due to high wind loads and driving rain by means of lip seals. However, with this type of windows and doors there are still sealing problems with regard to the effects of driving rain. Sealing problems are known in particular in the lower joint area between two laterally vertical frame spars or frames of a frame to be inserted in a building opening and a lower frame spar, which is also referred to as a threshold. The wind then pushes the water into the connection area below the vertical frame spars of the window frame and the horizontal threshold, so that the water can penetrate not only into the threshold area, but also transversely into the masonry via longitudinal capillary joints. To close gaps and to connect the frame spars to the threshold, a large number of different components and materials are used in a very small space, which are sealed with a sealing compound, for example made of a liquid plastic. A permanent connection of the materials and an adhesion of the sealing compound are not optimal. With regard to the known state of the art, optics and assembly are also neglected.

Furthermore, the joint areas of the respective vertical stiles and horizontal stiles or thresholds inevitably belong to the connection of two components. Such sliding sashes or slidable lift-and-slide sashes of windows or doors are known in the prior art.

the EP 2 202 378 A2 discloses a lift and slide sash of the State of the art. A lift and slide door with a lift and slide sash with a threshold has become known, which has a base profile and an extension profile. Both profiles extend over the entire width of the window or door, including the connections of its frames. For these connections, connecting elements are provided which can be attached to the ends of the elongated basic profile, preferably to the front ends. At the ends of the base profile connecting elements, for example in the form of corner connectors, are provided for mounting the frames, which extend over the entire depth (or width, transversely to the longitudinal direction and lengthwise extension) of the base profile. The corner connectors are designed as molded parts and their underside is adapted to the contour of the basic profile.

In particular on the outside or on the weather side, due to the large number of components at the ends, visible impact areas are formed that are directly exposed to the effects of the weather in an unprotected manner.

Next is from the EP 2 514 905 A2 a window frame for a composite window or a composite window door, with a stick frame body and a frame panel, which is attached to it while forming a free space therebetween, the stick frame body having a plurality of stick frame elements, and wherein the frame panel has a plurality of panel parts. The window frame has in the free space between the stick frame body and the frame panel in each case a sealing part in a corner area of the window frame, which is formed by a stick frame element that is lower in the installed position and an adjacent lateral stick frame element, the sealing part extending at least out of the corner area in the direction away from lateral stick frame element extends. Furthermore, a sealing part for such a window frame and a composite window or a composite window door, which are equipped with it.

The invention is based on the object of providing a functionally reliable and compact device for covering a sliding sash, folding-sliding sash or sliding lift-and-slide sash of a window or door, which eliminates the above disadvantages and has a good appearance for the window or door is inexpensive and can be assembled and adjusted in a simple, fast, safe and precise manner with little installation space.

According to the invention, the object is achieved by claim 1. Advantageous refinements of the invention emerge from the subclaims.

For the sealing closure, in particular the critical area below the frames in the transition to the threshold, it is proposed according to the invention that a cover device, which is preferably made of aluminum, be arranged at the lower end of the frames of the sliding sash, folding sliding sash or lifting-sliding sash of a window or door formed thin-walled cover plate and is shaped and arranged to seal against driving rain in such a way that it sealingly covers the gap to the horizontal threshold on the one hand and the space between the lower corner connecting elements and the weatherstrips attached to the threshold. This ensures that the rain hitting the surface of the window or door is diverted over the cover device having the frames and the threshold, so that it cannot penetrate into the frame structure. The design of the formed cover plate adapts itself flexibly in an advantageous manner with regard to thermal expansions occurring in the area of the lower profile components, such as the weatherboard and also the threshold, so that the required tightness is maintained.

For this purpose, the cover plate has a lower end section, which extends on the front surface almost over the entire width of the frame and goes beyond it in the vertical direction to the threshold and thereby covers the lower area of the frame and a partial area of the threshold. Thus, a bridge element is created which sealingly protects this critical area on a sliding sash or lifting-sliding sash on the outside of the window or a door against driving rain water.

In a further development of the invention, the lower free end portion of the cover plate running vertically to the frames is followed by a cover profile running horizontally in the longitudinal extension of the threshold, which connects almost seamlessly to the cover plates arranged on the respective frames. The cover plates and the cover profile together cover the entire lower area of the window frame in the horizontal direction and also in the vertical direction up to the critical joint area between the attachment of the frames Threshold, so that rainwater occurring due to the wind pressure or moisture caused by the weather conditions is safely and directly diverted through the covering device.

A simple, inexpensive production and the guarantee of functionality of a sealing connection of the cover device are achieved in that a shoulder is provided on the upper horizontal free end, preferably extending over the entire length of the cover profile. Accordingly, the shoulder runs horizontally, adapted to the length of the threshold, over the entire length of the window or door and forms a vertical or angled offset in the direction of the threshold, which is equal to the material thickness of the cover plate, from the surface that is visible on the surface.

In a further development of the invention for protection against the ingress of moisture or water and for uncomplicated assembly, the shoulder of the cover profile is shaped like a step. The first stage forms the flat, large-area surface of the cover profile and has an almost seamless, even contact surface with the cover plate. A second step forming shoulder of the cover profile runs in steps to the first step, the flat surface, with a support surface parallel to the surface. In a preferred embodiment, it is provided that the lower free end section of the cover plate overlaps the cover profile and rests on the support surface, the cover plate together with the cover profile visibly forming a U-shaped flush surface structure acting on the window or door as an integral unit .

Such a cover device ensures a component that is in line with the market with the cover plate in the basic shape as a cuboid and in a flat material thickness for simple assembly. The angular design of the cover plate in adaptation to the cover profile and other add-on parts, for example to sealing or connecting parts of the window or door, gives the window or door an optimal seal with a clear, seamless shape.

To achieve the advantages described above and below, the vertical cover plate and the horizontal cover profile are preferably made of aluminum. With the same attachments at the top and bottom of the Window or door and thus a uniform choice of materials, various surfaces of the visible surface of the cover plate and the cover profile can be galvanically, powdered, painted and brushed to match the additionally visible components, for example a lever. Preferably, by choosing aluminum, the cover plate and the cover profile can be manufactured simply and inexpensively and simply screwed, clipped or clamped, which represents a considerable simplification when fastening to the window or door. However, the use of other materials, such as a plastic material, is also conceivable and known.

For the sealing closure, in particular the critical joint area at the lower transition of the vertical frame spar, referred to as the frame to the horizontal frame spar, known as the threshold, it is proposed according to the invention that the vertical cover plate be directed on the contact surface facing the frame and the contact surface of the cover profile facing the second step carries a sealing means, preferably a sealing pad, and the horizontal cover profile is directed towards the threshold and has a longitudinal seal adjacent to the threshold. This ensures that the rain hitting the surface of the window or the door is diverted via the covering device so that it cannot penetrate into the frame structure. The design of the cover plate formed from aluminum and of the cover profile adapts flexibly in an advantageous manner with regard to thermal expansions that occur in the area of the lower frame, so that the required tightness is maintained. Dimensional inaccuracies that may occur, for example due to the manufacture of the window frame, can be compensated for by the sealing pad and / or by the longitudinal seal.

The cover plate and the cover profile on the window or door are preferably formed in one piece from a visual point of view. Before being installed in a building opening, the cover plate extends over the entire surface and is visible with a flat surface on the end face of the vertical frame spars or the frames. Fastening screws are used for optimum fastening and sealing of the vertical cover plate on the frames. In addition to a screw-type fastening, other fastening variants, such as clipping or clamping, are also possible. When the window or door is installed in a building opening, the covering device is completely covered by the masonry and the floor.

The following explanations relate as an example to a window or a door 1 with a slidable lift-and-slide sash 7, but also as a Can be designed as a sliding sash or as a folding sliding sash. In Figure 1 the basic structure of a window or a door 1 with a lift-slide sash 7 is shown schematically. The window or door 1 comprises an outer frame 2 to be inserted into a building opening, which is made up of two lateral frame spars 3, 3 'also known as frames, an upper frame spar 4 and a lower frame spar 5, which is also referred to as a threshold . Furthermore, an inactive leaf 6 and the sliding leaf as a lifting / sliding leaf 7, the inactive leaf 6 and the lifting / sliding leaf 7 being inserted into the frame 2. In the casement 8 and inactive leaf frame 8 '(in this embodiment of the present invention it is a wooden profile frame) of the lift-and-slide sash 7 or inactive leaf 6, a respective glazing 9, 9' is inserted. The sash frames and inactive sash frames 8, 8 'of the lift-slide sash 7 and the inactive sash 6 are made up of four spars, analogous to the frame 2. When the lift and slide sash 7 of the window or door 1 is closed, the lift and slide sash 7 is located in front of the lateral frame strut 3 of the window frame 2.

In other embodiments of a window or a door 1, two or more lift and slide sashes 7 can also be inserted into the frame 2. In order to ensure that the lifting and sliding sash 7 can be displaced with respect to the frame 2 or the inactive leaf 6, the lifting and sliding sash 7 and the inactive leaf 6 are arranged in two different parallel planes in the depth of the window frame 2. In the in Figure 1 The illustrated embodiment, the lifting and sliding sash 7 is arranged in a plane closer to the inside of the building than the stationary wing 6. The lower sash frame 11 of the lifting and sliding sash 7 has a carriage 12 with rollers (shown schematically) at both of its lateral ends, through which the lift and slide sash 7 is guided displaceably on a running rail, not shown, on the lower frame strut 5 or the threshold of the frame 2. Guide elements, not shown, are also arranged on the upper sash frame spar 10. In addition, a lift-slide fitting (not shown) is attached to the sash frame 8 of the lift-slide sash 7, by means of which the lift-slide sash 7 can be raised or lowered in the vertical direction for opening and closing and also locked.

the Figure 2 shows an exploded view of a joint area 13 between the two lateral frame spars 3, 3 ', also known as frames, and the lower one Frame spar 5, which is also referred to as a threshold. A critical point for a leakage problem with regard to driving rain weather influences is seen in a joint area 13 or connection area below the vertical frame spars of the window frame and the horizontal threshold, after which the water is pressed by the wind into the joint area 13 so that the water does not can penetrate transversely into the masonry only in the area of the threshold, but also via longitudinal capillary joints.

In order to remedy this problem and to produce a sealing closure, points to the Figures 1 to 6 the sliding sash 7 or lifting-sliding sash of a window or a door 1 at the lower end 14, 14 'of the frames 3, 3' of the sliding sash 7 or lifting-sliding sash of a window or door has a cover device 15, which is preferably formed from an aluminum thin-walled cover plate 16 and is shaped and arranged to seal against driving rain in such a way that it sealingly covers the gap to the horizontal threshold 5 on the one hand and the space 18 between the weather legs 19 attached to the lower corner connecting elements 17 and the weatherstrips 19 attached to the threshold 5. This ensures that the rain hitting the surface of the window or door 1 is diverted over the cover device 15 having the frames 3, 3 'and the threshold 5 so that it cannot penetrate the frame structure. The design of the shaped cover plate 16 adapts flexibly with regard to thermal expansions that occur in the area of the lower profile components, such as the weather legs 19 and also the threshold 5 Fig. 2 and Fig. 4 show so that the required tightness is maintained.

To this end, the cover plate 16 shows Fig. 2 a lower end portion 20, which extends on the front surface 21, 21 'of the frames 3, 3' almost over the entire width 22 of the frames 3, 3 'and extends in the vertical direction to the threshold 5 beyond and after the Figures 4 to 6 covers the lower area of the frames 3, 3 'and a partial area of the threshold 5 across. Thus, with the cover plate 16, a bridge element is created which sealingly protects this critical joint area on the sliding sash 7 or lifting-sliding sash on the outside 23 of the window or a door 1 against driving rain water.

In the Figures 1 and 3 As can be seen, the lower free end section 20 of the cover plate 16, which runs vertically to the frames 3, 3 ', is followed by a cover profile 24 running horizontally in the longitudinal extension of the threshold 5, which is almost seamlessly flat with a surface 28 on the respective frames 3, 3 'arranged cover plates 16 with a surface 28'. Also recognizable in the figures, the cover plates 16 and the cover profile 24 together cover the entire lower area of the window frame 2 in the horizontal direction and furthermore in the vertical direction up to the critical joint area 13 between the attachment of the frames 3, 3 'to the threshold 5 , so that rainwater occurring due to the wind pressure or moisture caused by the weather conditions is safely and directly diverted through the covering device 15.

For the sealing connection of the cover device 15 is after Figures 2 and 6th a shoulder 27 is provided at the upper horizontal free end 25 over the entire length 26 of the cover profile 24. The paragraph 27 runs after Fig. 6 adapted to the length of the threshold 5 horizontally over the entire length of the window or the door 1 and, starting from the base, which is to be seen in the foreground, simulates the flat surface 28 of the cover profile 24 Fig. 6 a vertical or angled offset 29 in the direction of the threshold 5, which corresponds to the material thickness of the cover plate 16.

To do this, according to the Figures 2 and 6th the shoulder 27 of the cover profile 24 is stepped. The first step 30 forms the flat, large-area surface 28 of the cover profile 24 and has an almost seamlessly flat contact surface with the cover plate 16. A second step 31 forming shoulder 27 of the cover profile 24 runs in a stepped manner to the first step 30 of the flat surface 28 with a support surface 32 parallel to the surface 28. The support surface 32 offers the lower free end portion 19 of the cover plate 16 a flat overlapping contact when the cover profile 24 is reached on the support surface 32. The cover plate 16 and the cover profile 24 form according to the Figures 1 , 3 and 6th Visibly recognizable as an integral structural unit acting on the window or door 1, a U-shaped surface structure that is flush with the surface.

Fig. 1 and Fig. 4 show the covering device 15 with the window or the door 1 in the installed position. The overall package, consisting of the covering device 15 and the window or door 1, provides a component that is simple and inexpensive to manufacture in line with the market, with the cover plate 16 in the basic shape as a cuboid and with a flat material thickness. The angular rectangular design of the cover plate 16 in adaptation to the cover profile 24 with other attachments, for example based on other covering components of the window or the door 1 itself, gives the window or door 1 the overall impression of a clear, seamless shape.

Both the cover plate 16, which is vertically aligned in a rectangular shape, and the horizontal cover profile 24 are preferably made of aluminum. With the same visible add-on parts at the upper and lower end of the window or door 1 and thus a uniform choice of material, various surfaces of the visible surface of the cover plate 16 and the cover profile 24 can be galvanically, powdered, painted and brushed onto the additionally visible components, for example an operating lever or can be adapted to other visible cover components. Preferably, by choosing aluminum as the material, the cover plate 16 and the cover profile 24 can be simply screwed, clipped or clamped by means of fastening screws 36, which represents a considerable simplification when fastening to the window or door 1. However, the use of other materials, such as a plastic material, is also conceivable and known.

For a sealing closure, in particular in the critical joint area 13 at the lower transition of the vertical frame spars 3, 3 ', referred to as the frame to the horizontal frame spar 5, referred to as the threshold Fig. 2 and Fig. 6 the vertical cover plate 16 has a sealing means as a sealing pad 34, 34 '. In this case, the sealing pad 34 is arranged on the non-visible contact surface 33 pointing towards the frames 3, 3 ', the sealing pad 34' being in contact with the contact surface 32 of the cover profile 24. The sealing pads 34, 34 'rest over their entire surface on the contact surface 33, 32 and provide a surface-covering seal. Likewise, however, a circumferential sealing tape can only be used around the outline of the cover plate 16. The horizontal cover profile 24, on the other hand, has a longitudinal seal 35 directed towards the threshold 5 and resting against the threshold 5. This ensures that the rain hitting the surface of the window or door 1 is diverted via the covering device 15 so that it cannot penetrate into the frame structure. The design of the molded from aluminum The cover plate 16 and the cover profile 24 advantageously adapt flexibly with regard to thermal expansions that occur in the area of the lower frame 2, so that the required tightness is maintained. Possible dimensional inaccuracies that occur, for example due to the manufacture of the window frame 2, can also be compensated for by the sealing pad 34, 34 ′ and / or by the longitudinal seal 35.

The cover plate 16 with the cover profile 24 on the window or door 1 are seen as an integral unit due to the seamless transition point.

The present invention has been described above with reference to a window or a door 1 primarily with a lift and slide sash 7. For the person skilled in the art, however, it is evident that the explanations can be transferred in the same way to a corresponding window or door 1 with a folding / sliding sash or sliding sash.
