EP2594720B2 - Window and door frames that can be covered with various materials made of thermoplastic, weldable material - Google Patents

Description

The invention relates to window and door frames which are made of profiles made of thermoplastic, weldable material, e.g. made of PVC, which, be it on the outside, exposed to the weather, or on the inside, facing the occupied room, with elements made of different materials, e.g. made of aluminum, wood or glass.

Profiles for the production of window and door frames are known which can be covered with metal profiles or with profiles made of other materials using spaced clip-on elements attached to the said profiles. This system is often used for the external protection of weather conditions for wooden frames due to the external attachment of aluminum profiles.

It is also the external attachment of metal profiles to frames made of plastic, e.g. of the type reinforced with fibers, are known in that the profiles which form the frame are provided with longitudinal webs with hanging projections, behind which corresponding projecting longitudinal webs which are provided on the rear side of the cladding profiles and are provided with a hanging projection along the outermost edge can be clipped on.

From the FR 2948719 sash and stick frames are known which can be covered with clipped profiles; these cover profiles are attached to the frame with one long side as individual, not connected parts, and clipped on with the second long side. This type of attachment means that the miter joints on the front of the cover profiles open ugly and with different widths due to the different thermal expansion coefficients between the frame, which is made of PVC, for example, and the cover profiles, which are made of aluminum, for example in the corner areas there are conspicuous deformations, tensions or even damage.

From the DE 10059849 A1 Fastening systems are known between a pane which projects circumferentially to the insulating glass pane on the outer edge and a fastening element or adhesive element used on the casement. It is also known that a flange is formed on said fastening or adhesive element, which covers the circumferential, protruding edge of this glass pane, with respect to all or most of the glass thickness. The systems proposed in this document have the disadvantage that the dimensions of the glass pane seldom fit exactly within the circumferential cover flange and that an unattractive and irregular joint between the glass edge and the cover flange usually remains visible.

There are also known aluminum composite profiles with interruption of the cold bridges by means of the interposition of anchored plastic elements, usually by rolling them up on the metal profiles. In order to improve the thermal insulation, the plastic elements take on considerable dimensions, while the metal profiles have reduced cross-sections.

The aforementioned solutions do not provide that the profile itself, which forms the frame, is cladding on both sides made of different materials, e.g. made of wood on the inside facing the living room and made of aluminum on the outside which is exposed to the weather. Furthermore, the known profiles which form the frame, in that they have a cross section which is approximately reduced by the cross section of the attached cladding profile, do not have a structure which enables the fittings to be anchored efficiently and guarantees good thermal insulation, furthermore these frames do not offer a high profile dimensional stability. In particular, the profiles made of fiber-reinforced plastic and the aluminum composite profiles cannot be equipped with co-extruded seals, and their welding is also not common, which means that water can run in at the corners of the frame and that the seals must be attached in a subsequent work phase and that this takes place at the corner areas without sealing continuity.

The profiles for covering the stick frame and or the sash frame are clipped onto the frame as individual miter-cut parts in the known systems. This has the consequence that, in particular because of the different thermal expansion coefficients of the material from which the frames are made and the material from which the cover profiles are made, at the corner areas where the miter-cut ends of the cover profiles meet, either unsightly joints become visible or Tensions occur which lead to the deformation of the cover profiles, to the loosening of the clip connections or to their damage.

The document DE7732328U shows frames, the profiles on the exposed to the weather side hang-in webs for attaching cover profiles, the cover profiles are connected by means of connecting brackets to form stable cover frames.

The invention has for its object to use a single typology of profiles made of thermoplastic, stick and casement frames for windows and doors to produce different design features, all of which have high thermal insulation, high dimensional stability, without the use of stiffening elements, a structure on which Fittings can be anchored efficiently, have and furthermore are provided with coextruded seals and are prepared in order to be able to comfortably clad the frame on both sides with different materials, whereby the problems of different thermal expansion which Frame with a load-bearing function with cover made of different materials can be eliminated. Furthermore, the invention has the task of making said frames absolutely tight in the corner areas against the ingress of water into the profiles and to provide the efficient outflow of water which has penetrated between the casement frame and the stick frame.

Another object of the invention is, in the case of insulating glass panes in which the outer pane, in relation to the other panes, forms a protruding edge and thus completely covers the casement, to cover the peripheral edge, which corresponds to the thickness of this glass pane, as cleanly as possible by means of a corresponding profile , so that any deviations from the cut dimensions can be compensated for in order to achieve a continuous, seamless cover.

To achieve this object, the invention proposes a framework according to claim 1. The cross section of the profile made of weldable, thermoplastic, e.g. made of PVC, can be divided by several internal longitudinal walls in order to obtain a large number of chambers which, because of the reduced distance between the said walls, offer multiple anchoring for the fastening screws of the fittings. Said internal structure of the profiles, together with the protruding parts for formation, in the case of a wing, the stop for receiving the glass pane and / or the stop acting on the stick frame, or in the case of a stick frame, the outer stop against which of the Sash frame in closed position ensures an efficient connection in the corner areas by welding which gives the frame remarkable shape stability without the need to use elements to increase the stability of the frame. Furthermore, the profiles are according to the invention, be it on the inside, which is directed towards the living space, or on the outside, with protruding longitudinal webs which are provided with a hanging projection along the outermost protruding edge. These said webs with a hanging projection are prepared for the reception of blessings which come from the back of e.g. metallic cover profiles protrude which cover the entire inner or outer surface of the frame profile. In the case of covers made of wood or wood derivatives, these can have the form of strips and have the longitudinal grooves corresponding to the longitudinal webs protruding from the frame profile, or profiles or elements can be attached to said cover strips which have elastic clip-on longitudinal webs which are behind the hanging projections on the longitudinal webs of the frame profile snap. The cover elements according to the invention are shaped so that they exert pressure on the seals provided on the frame through their outermost longitudinal edges, so that they rest efficiently and permanently on the glass or on the corresponding frame and at least partially cover the seals. This pressure prevents the ingress of water or warm air from the living space behind the attached cover.

The structure of the two coverable sides of the frame profile is shaped in such a way that it has surfaces for the attachment of glass panes or, e.g. in the case of door profiles, for the attachment of plates made of metal or other materials, which lie in a plane parallel to the plane of the glass pane of the window or to that of the door leaf. Furthermore, the same grooves which are provided between the hanging webs for the cladding elements or which are provided between these and an adjacent wall of the profile, in certain cases in a known manner for the application of profiles for covering joints, e.g. between a glass pane and the frame. If a glass pane is fitted instead of an inner cladding, a known moisture-attracting spacer of the type for the production of heat-insulating glass panes is used in the existing space. In this case, the attached glass completely covers the frame of the wing, including the all-round seal, and gives the wing an innovative aesthetic.

In this case, the clipped-on profile for gluing or fastening is provided with a toothed shoulder on which a profile with a T-shaped cross-section engages with a correspondingly toothed flange and can be shifted until it is on the outer edge of the glass pane fits snugly, or also presses on the corresponding seal on the frame and partially covers it. In this way, a practically seamless covering of the outer edge of the glass pane is achieved, even in cases where it has not been cut or glued very precisely.

The difference in expansion between the frame and the cover, which, after the individual profiles are connected in the corner regions, has the shape of a frame, is effectively absorbed, in part because of the possible longitudinal displacement between the window or door frame and the frame of the cover, and partly due to the elasticity of the hanging bars. In particular, the cover profiles or strips which are attached to the window or door frame on the side of the living space are secured in their mounting position by means of the fastening screws of the fittings.
According to the invention, the longitudinal webs with the hook-in lugs on the profiles of the frame and the sash frame are milled in all four corner areas of the frame to thereby offer the cover frame the possibility, in the event of tension between the sash frame or the frame and the corresponding cover frame, to be able to evade without the said stresses becoming visible deformations or lead to damage.
The profiles which form the sash frame and also those which form the corresponding floor frame are connected in a known manner, together with the extruded seals, by welding, which creates a structure which is sealed against the ingress of water in the corner areas. The lower horizontal window or door profile has a cross section which, in the area immediately within the shape of the outer stop, provides a known channel for the absorption of the water which may have penetrated between the sash and the stick. It is known to connect this channel to the outside for the purpose of draining said water by drilling the profile in the area of the lowest point of said channel with a slight inclination to the outside in relation to a vertical and by fitting the same profile the point corresponding to this first hole is drilled horizontally from the outside, as tangent as possible to the inner surface of the lower wall of the profile.

Profile 1a which is the frame of a window ( Fig. 1 and 3 ) forms on the inside facing the living space, projecting, spaced-apart longitudinal webs 1b, which, at the free outermost edge, have a hanging projection, between these webs 1b further walls 1f can be provided which may form a closed chamber whose wall with the outermost edges of the suspension webs 1 b are aligned. Said webs 1b can accommodate webs 10b which protrude from a cladding metal profile 10, or a wooden strip 10h can be attached directly to the same webs 1b due to removal of walls 1f. Be it the metal profile 10 or the wooden strip 10h also act as a stop for the seal 2y protruding from the window sash. In the same area of the suspension webs 1b, the profile 1a of the frame 1 has on the inside a plurality of walls 1p which are arranged close to one another in order to offer multiple and efficient anchoring of the fastening screws 5 of the cones. The screws 5a for fastening the locking fittings penetrate at least one of the webs 1b and 1f, or the wooden strip 10h. On the outside exposed to the weather, the same profile 1a has two mutually spaced hanging webs 1c, on which corresponding webs 10c of a metal profile 10a hang. According to the invention, these webs 1c are milled off in the corner regions of the frame ( Fig. 1b ), while the cover profiles 10, 10a are connected by connection brackets 10w, 10v, 10x to form stable frames. The profile 1 a also has on the outside a vertical flange 1 d on which an extruded seal 1 x is provided which acts on the wing 2 on the outside. Between said vertical flange 1d and a projection 1e with seal 1y, the profile has a known channel for the purpose of receiving any water that may have penetrated between the wing 2 and the frame 1; said water can flow out through the holes 6.

The profile 2a of the casement 2 of a window is of the type with a heat-insulating glass 7 glued to the vertical wall 2f of the profile 2a, and the same protruding part with the said wall with adhesive surface, on the side facing the living space, with two hanging webs spaced apart from one another 2b, which accommodate the corresponding hanging webs 20a projecting from a metallic cover profile 20, the hanging webs 3a of a metal or plastic profile 3 for gluing on a glass pane 7a or the webs 4a of an intermediate metal or plastic profile 4 which is fastened to a wooden cover strip can. Said glass pane 7a can only be glued to the inwardly facing surface of web 2c, which forms the stop of wing 2, or also to said intermediate profile 3, in any case there is a known moisture-absorbing space in the gap caused by the gluing on of glass pane 7a Spacer 70, 70a housed ( Fig. 2 ). The outermost longitudinal edges of said cover profiles 20, or the strip 20h, press against the seals 2z and 2y by covering them. The glued-on glass pane 7a, 7c also covers the seal 2y with its peripheral edge. The circumferential outer edge of the glued-on pane 7a, 7c is seamlessly covered by a profile 30 which is T-shaped in cross section and which engages with its toothed flange 30a on a correspondingly toothed shoulder 3b of the intermediate profile 3. The same intermediate profile 3 can also be attached to the outside of profile 1 a of frame 1 in order to glue cover profiles or cover plates 24 made of different materials ( Fig. 1a ) to enable always the same, on the inside of the profile 2a del wing 2, clipped intermediate profile 3, can also be used for gluing cover elements 24 made of different materials ( Fig. 2b ).

To the outside, the same profile 2a of the wing 2 is provided with a hanging web 2d and with an adjacent groove, for the purpose of accommodating a rubber seal 2x which covers the joint between the profile 2a and the attached glass pane 7 in a known manner. On the outside, the profile 2a can also have two mutually parallel suspension webs 2d for the purpose of attaching a metallic cover profile 20b ( Fig. 3 ).

In the case of a wing 2v, composed of an inner frame with profiles 2i and an outer frame with profiles 2e in order to be able to accommodate a blind in the space between them, the profiles 2i of the inner frame, in the direction of the living space, have similar technical features as they do Profile 2a has, for example, being able to hold a metallic cover profile 20m. The invention does not rule out that the entire outer frame is composed, for example, of aluminum profiles 2e, which are not covered in this case. The profile 2e which forms the outer frame ( Fig. 4 ) which is articulated on the inner frame 2i for the purpose of opening, is provided with a vertical wall 2g for gluing on the glass pane 7b and with a groove in which a corresponding anchoring lug 20s of a metallic cover profile 20n engages.

According to the invention, the inner stop 2c on the profiles 2a of the wings 2, or on the profiles 2i of the wings 2v, which are equipped with blinds ( Fig. 4 ), towards the living area, a flat surface on which lies in a plane parallel to the plane of the glass pane 7 in order to provide a support for the attached cover profiles 20, 2m, 20h, or an adhesive surface for the attachment of a glass pane 7a ( Fig. 2 ). The cover profiles 20, 20b for the sash frames 2a, 2v are also connected to form-stable frames by means of connecting brackets 20w, 20v, 20u, while the hanging webs 2b on the sash frame profiles 2a, 2v are milled in the corner regions of the frame ( 1 c) , The intermediate profiles 3, 4 which are clipped onto the casement for the gluing of glass panes 7a, 7c and which may have a toothed extension 3b, can be secured for safety in the central area by at least one screw 3c on the casement 2a, 2v.

In the case of wings 2t composed of profiles 23 of glass doors ( 5, 6 ), these profiles are provided on one side with projecting suspension webs 23b and on the opposite side with suspension projections 23g. On the side with the attachment webs 23b, a cover profile 23i can be clipped on by means of attachment webs 23a or, by using the web 23c which forms a stop and a possible profile 8a, a plate 8 made of different materials can be glued on. On the opposite side, on the other hand, the hanging webs 23a of a metallic cover profile 23e engage on the hanging projections 23g; alternatively, a metal or plastic profile 24 can be clipped onto the same hanging projections 23g, to which a plate 9 of different shape and of different material can be glued. Said profile 24 enables the balancing of the loads which occur due to the different thermal expansion between the profile 23 of the frame and the attached plate 9, furthermore said profile 24 prevents excessive heating of the underlying profile 23 when exposed to the sun.
