DESCRIPTION

Door and window frame made of weldable thermoplastic material, which can be coated with different material

The invention relates to door and window frames that are made from profiles of weldable thermoplastic material, for example PVC, which are coated, either on their outer side exposed to weather influences, or on their inner side. directed towards the inhabited space, with elements of different materials, such as aluminum, wood or glass.

Profiles are known for the manufacture of door and window frames that, using spaced-apart snap-together elements attached to said profiles, can be covered with metal profiles or with profiles of other materials. This system is frequently used, through the external placement of aluminum profiles, as external protection against weather influences for wooden frames.

The external placement of metal profiles in frames that are made of plastic, for example of the type reinforced with fibers, is also known, being provided in the profiles that form the frame longitudinal ribs with hooking projections, after which they can be snapped , elastically, corresponding protruding longitudinal ribs, which are provided on the rear side of the covering profiles and are provided along the outermost edge with a hooking projection.

From FR 2948719 sheet frames and fixed frames are known which can be coated with snap-in profiles; these covering profiles being hooked, as individual pieces not joined together, to the frame with one longitudinal side and snap-fit with the second longitudinal side. This type of installation implies that the miter joints on the front side of the covering profiles, due to the different coefficients of thermal expansion between the frame, which is, for example, PVC, and the covering profiles, which are, for example, made of aluminum, they open in different measures, in an unsightly way, or that in the corner areas visible deformations, tensions or also damages occur.

From DE 10059849 A1 fixing systems are known between a glass projecting with respect to the insulating glass pane running along the outer edge and a fixing element, or adhesive element, inserted in the sheet frame. It is also known that a flange covering the protruding surrounding edge of this glass pane, in relation to all or most of the thickness of the glass, is formed in said fixing or adhesive element. The systems proposed in this document have the disadvantage that the dimensions of the glass pane rarely fit exactly within the surrounding covering rim and that therefore an unattractive, uneven joint between the edge is generally conspicuously visible. glass and coating flange.

Aluminum composite material profiles are also known with interruptions of the thermal bridges by means of the interposition of anchored plastic elements, generally by winding on the metal profiles. Under the requirement of improving thermal insulation, the plastic elements take considerable measures while the metal profiles have reduced cross sections.

The aforementioned solutions do not foresee that the profile that forms the frame itself can receive on both sides coatings of different materials, for example wood on the inner side facing the house and aluminum on the outer side exposed to weather influences. Furthermore, the known profiles that make up the frame do not have, due to the fact that they have a cross section that is more or less reduced in the cross section of the placed cladding profile, a structure that enables an effective anchoring of the fittings and guarantees good insulation thermal, and also these frames do not offer high stability. In particular, profiles made from fiber-reinforced plastic and aluminum composite profiles cannot be equipped with co-extruded gaskets, nor is their welding common, which means that water can enter the corners of the frame and that the Placement of the gaskets has to be done in a later phase of work and that this occurs in the corner areas without gasket continuity.

Profiles for covering fixed frames and / or sash frames snap-fit into the frame, in known systems, as individual pieces, miter cut. This has the consequence that, in particular due to the different coefficients of thermal expansion of the material of which the frames are made and of the material of which the covering profiles are made, in the corner areas where the miter-cut ends of the profiles Unsightly joints are visible or stresses appear which lead to deformation of the covering profiles, to snap-fit joints or to damage.

The DE7732328U utility model shows frames, presenting the profiles on the side exposed to meteorological influences longitudinal hooking ribs for fixing covering profiles, the covering profiles being joined by means of union brackets to covering frames in a stable way .

The objective of the invention is to manufacture, by means of a single typology of thermoplastic plastic profiles, fixed and leaf frames for doors and windows with different construction characteristics, all of which have high thermal insulation, high shape stability, without use stiffening elements, a structure to which the fittings can be anchored efficiently, and being equipped with co-extruded gaskets and being prepared to be able to comfortably cover the frame on both sides with different materials, eliminating the problems of different thermal expansion that they appear in the case of frames with support function covered with different materials. The object of the invention is furthermore to design said frames in the corner areas in an absolutely watertight manner against the penetration of water into the profiles and to provide for an effective evacuation of the water that has penetrated between the sheet frame and the fixed frame.

Another object of the invention is to coat, in the case of insulating glass panes in which the outer pane forms, with respect to the other pane, a protruding edge and therefore completely covers the sheet frame, the corresponding surrounding edge. with the thickness of this glass pane in the cleanest way possible by means of a corresponding profile, so that possible deviations in the dimensions cut to size can be compensated to achieve a seamless surrounding coating.

To solve this objective, the invention proposes a frame according to claim 1. The cross section of the weldable thermoplastic plastic profile, for example PVC, can be divided by several internal longitudinal walls to obtain a high number of chambers that, due to at the reduced distance of these walls from each other, they offer a multiple anchor for the fixing screws of the fittings. Said interior structure of the profiles, together with the projecting parts with respect to the configuration, in the case of a sheet, of the stop for the accommodation of the glass pane and / or of the stop acting on the fixed frame, or in the case of a fixed frame, of the external stop against which the leaf frame leans in the closed position, ensure in the corner areas an effective joint by welding, which gives the frame a remarkable stability of form without requiring the use of elements with a view to increasing the stability of the frame. Furthermore, the profiles according to the invention, either on the inner side facing the house, or on the outer side, are provided with protruding longitudinal ribs which are provided along the outermost protruding edge with a hooking projection . Said ribs with hooking projection are prepared for the accommodation of saw teeth that protrude from the rear side of covering profiles, for example metal, covering the entire interior or exterior surface of the frame profile. In the case of wood or wood-based coatings, these can be in the form of slats and the longitudinal ribs that protrude from the frame profile have corresponding longitudinal grooves or profiles or elements with snap ribs can be placed on said covering strips. elastic pressures that snap behind the hooking projections on the longitudinal ribs of the frame profile. The covering elements according to the invention are shaped in such a way that they exert a pressure on the gaskets provided in the frame by their outermost longitudinal edges, so that they rest effectively and permanently on the glass, or on the frame. corresponding, and cover the gaskets at least partially. This pressure prevents the penetration of water or hot air from the house behind the installed covering.

The structure of both coated sides of the frame profile is configured in such a way that it has surfaces for the installation of glass panes or, for example in the case of door profiles, for the installation of metal panels or other materials, which are They are located on a plane parallel to the plane of the glass pane of the window, or that of the door leaf. Furthermore, the same grooves that are provided between the hooking ribs for the cladding elements or that are provided between them and an adjacent wall of the profile, can be used in certain cases in a known manner for the placement of profiles for the covering of joints, for example between a glass pane and the frame. In the case of a glass pane instead of an interior lining, a known moisture-absorbing spacer element of the type used for the manufacture of thermally insulated glass panes is used in the gap present. In this case, the placed glass completely covers the sash frame together with the surrounding gasket and gives the sash an innovative look.

In this case, the snap-fit profile is provided, for adhesion, or fixing, of the covering profiles, with a toothed appendix to which a T-shaped profile is hooked in its cross section with a correspondingly toothed flange and thus it can be pushed until it rests fully on the outer edge of the glass pane, or it can also press on the corresponding gasket in the frame and partially cover it. In this way, a virtually seamless coating of the outer edge of the glass pane is achieved, and in particular also in cases where it has not been cut to size or adhered very precisely.

The expansion difference between the frame and the covering, which, after their individual profiles have been joined in the corner areas, is shaped like a frame, is effectively assumed and, in particular, in part due to possible longitudinal displacement between the window or door frame and the covering frame, and partly due to the elasticity of the hooking ribs. In particular, the covering profiles or slats that are placed in the window or door frame on the side of the house are secured in their mounting position by means of the hardware fixing screws.

According to the invention, the longitudinal ribs are milled with the hooking projections on the profiles of the fixed frame and of the leaf frame in the four corner areas of the frames, thereby offering the covering frame the possibility of be able to deviate in case of stresses between the leaf frame or the fixed frame and the corresponding covering frame, without these stresses leading to visible deformations or damage.

The profiles that form the sash frame and also those that form the corresponding fixed frame are joined in a known way, together with the extruded gaskets, by welding, which makes a watertight structure appear against the penetration of water in the corner areas . The lower horizontal leaf or door profile has a cross section that, in the area directly inside the conformation of the outer stop, provides a known channel for receiving the water that has eventually penetrated between the leaf and the fixed frame. It is known to communicate this channel, with a view to the evacuation of said water, with the exterior drilling the profile in the area of the lowest point of said channel, with a slight inclination outwards with respect to a vertical and drilling the same profile in the point corresponding to this first perforation from the outside horizontally, as tangent as possible with the interior surface of the bottom wall of the profile.

The invention is explained in more detail with the help of some preferred embodiments, schematically represented in the accompanying drawings, of door and window frames of weldable thermoplastic material that can be coated with different material; In this regard the drawings are for explanatory purposes only, not limiting.

Figure 1 shows a cross section through the lower horizontal part of a window pane with heat insulating glass and through the corresponding part of the fixed frame; In this regard, the glass can be seen from the outside in all its extension and is adhered to an inner stop of the sheet frame; Both frames are covered on both sides by metal profiles and the fixing of a hinge and a metal element of the window closing mechanism is also shown.

Figure 1a shows in detail the external part of the fixed profile represented in Figure 1 with the external covering that is placed by means of adhesion on a press fit intermediate profile.

Figure 1b shows on a smaller scale the same fixed frame shown in Figure 1 with the details corresponding to the corner area of the outer covering frame, the fixed frame and the inner covering frame in a front view from the inner side. .

Figure 1c shows on a smaller scale the same sheet frame shown in Figure 1 with the details corresponding to the corner area of the inner covering frame and the sheet frame; In this regard, the covering frame is shown from the side of the connecting bracket and the leaf frame from the side of the longitudinal ribs with hook projection.

Figure 2 shows in cross section the lower part of a window sash frame, the frame being made from a profile identical to that of Figure 1, but with a glass pane together with a moisture absorbing spacer element, which is adhered to the outer side of the inner stop of the sheet by means of an intermediate profile in whose toothed appendage a correspondingly toothed flange of a T-shaped profile is inserted in its cross section for seamless coating of the outer edge of the glass of glass.

Figure 2a shows in cross section a detail of the same leaf profile represented in Figure 2 with a covering profile which is adhered to an intermediate profile, which is press-fitted on the inner side of the leaf frame.

Figure 3 shows the cross section through the lower horizontal part of a window sash frame and through the corresponding fixed frame, both frames being covered on the outside by metal profiles and on the inside by wooden slats.

Figure 4 shows the cross section through the lower horizontal part of a window pane frame with glass pane in front and the opening frame with an intermediate space for a Venetian blind, both frames being covered by metal profiles.

Figure 4a shows the same window frame shown in Figure 4, without a front glass and without the corresponding frame, but with a triple insulating glass, the glass on the housing side completely covering the top of the sheet frame and being adhered to an intermediate profile, snap-fit into the sash frame; In this regard, the outer edge of this glass, as also shown in Figure 2, is seamlessly covered by a T-shaped profile in its cross section.

Figure 5 shows the horizontal cross section through a part of the sheet frame of a glass door and through the corresponding fixed frame, the sheet frame being covered on both sides by metal profiles, the fixed frame consisting of a metal profile traditional with interruption of thermal bridges.

Figure 6 shows the horizontal cross section through a part of the sheet of a glass door, the frame being made up of the same profile shown in Figure 5 and metallic or non-metallic covering panels being placed on both sides; In this regard, the surrounding outer edge of the panel covering the top of the sheet frame is seamlessly covered by a profile inserted in a T-shape in its cross section.

The profile 1a that forms the fixed frame of a window (Figures 1 and 3) has protruding longitudinal ribs 1b on the inner side facing the house, spaced apart, which have a hooking projection on the outermost free edge; Between these ribs 1b additional walls 1f can be provided, which eventually form a closed chamber whose wall is aligned with the outermost edges of the hook ribs 1b. Said ribs 1b can accommodate ribs 10b protruding from a metal lining profile 10 or can be placed on ribs 1b themselves, after removal of walls 1f, directly a wooden slat 10h. Either metal profile 10 or wooden slat 10h also act as a stop for gasket 2 and protruding from the window sash. In the same area of the hooking ribs 1b, the profile 1a of the fixed frame 1 has several walls 1p on the inner side that are arranged close to each other to offer multiple and effective anchoring of the fixing screws 5 of the hinge. Screws 5a for fixing the closing hardware penetrate at least one of the ribs 1b and 1f, or in the wooden strip 10h. On the outer side exposed to meteorological influences, the same profile 1a has two hooking ribs 1c spaced from each other in which corresponding ribs 10c of a metal profile 10a are hooked. These ribs 1c are milled according to the invention in the corner areas of the frame (Figure 1b), while the covering profiles 10, 10a are joined by connecting brackets 10w, 10v, 10x to form frames in a stable manner. The profile 1a also has, on the outer side, a vertical flange 1d in which an extruded gasket 1x is provided which acts on the outside of the sheet 2. Between said vertical flange 1d and a projection 1e with gasket 1y, the profile has a known channel with a view to housing the water that may have penetrated between the sheet 2 and the fixed frame 1; said water can be evacuated through the perforations 6 outwards.

The profile 2a of the window sash frame 2 is of the type with heat insulating glass 7 adhered to the vertical wall 2f of the profile 2a. The same protruding part with said wall with an adhesion surface is provided, on the side facing the house, with two longitudinal hooking ribs 2b spaced from each other that can house the corresponding hooking ribs 20a protruding from a metal covering profile 20 , the hooking ribs 3a of a metal or plastic profile 3 for the adhesion of a glass pane 7a or the ribs 4a of an intermediate metal or plastic profile 4 that is fixed to a wooden covering strip. Said glass pane 7a may be adhered exclusively to the inwardly oriented surface of the rib 2c that forms the stop of the sheet 2 or also on said intermediate profile 3; in any case, in the intermediate space that appears when the glass pane 7a adheres, there is housed a known moisture absorption distance element 70, 70a (figure 2). The outermost longitudinal edges of said covering profiles 20, or of the strip 20h, press against the packings 2z and 2y coating them. The bonded glass pane 7a, 7c also covers the gasket 2y with its surrounding edge. The surrounding outer edge of the bonded glass 7a, 7c is seamlessly covered by a T-shaped profile 30 in its cross section which engages with its serrated flange 30a in a correspondingly serrated appendix 3b of intermediate profile 3. The same intermediate profile 3 can also be placed on the outer side of profile 1a of frame 1 to enable adhesion of covering profiles or covering panels 24 of different materials (Figure 1a), and the same intermediate profile 3 can also be used to press-fit on the inner side of the profile 2a of the sheet 2 for the adhesion of covering elements 24 of different materials (figure 2b).

Outwardly, the same profile 2a of the sheet 2 is provided with a hooking rib 2d and an adjacent groove, with a view to housing a 2x rubber gasket, which frontally covers in a known manner the joint between the profile 2a and the glass glass 7 placed. On the outer side, the profile 2a can also have two hooking ribs 2d parallel to each other, with a view to placing a metal covering profile 20b (Figure 3).

In the case of a sheet 2v composed of an inner frame with 2i profiles and an outer frame with 2e profiles, to be able to house a Venetian blind in the interior space, the profiles 2 i of the inner frame have characteristics towards the house techniques similar to those presented in profile 2a, for example, can accommodate a 20m metal covering profile. 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 that forms the outer frame (figure 4) that is hinged to the inner frame 2 i, with a view to its opening, is provided with a vertical wall 2g for the adhesion of the glass pane 7b and with a slot in which it hooks a corresponding anchoring shoulder 20s of a metal covering profile 20n.

According to the invention, the internal stop 2c in the profiles 2a of the leaves 2, or in the profiles 2i of the leaves 2v that are equipped with Venetian blinds (Figure 4), in the direction of the house, presents a smooth surface that is located in a plane parallel to the plane of the glass pane 7, to offer a support for the covering profiles 20, 2m, 20h placed, or an adhesion surface for the placement of a glass pane 7a (figure 2). Also the covering profiles 20, 20b for the leaf frames 2a, 2v are joined by means of connecting brackets 20w, 20v, 20u to form frames in a stable way, while the hooking ribs 2b in the leaf frame profiles 2a, 2v are milled in the corner areas of the frame (figure 1 c). The intermediate profiles 3, 4 that are press-fitted for the adhesion of glass panes 7a, 7c on the sash frame and possibly have a serrated appendix 3b, can be secured to the sash frame 2a, 2v, for greater security, in the central area by means of at least one screw 3c.

In the case of sheets 2t, consisting of profiles 23, of glass doors (Figures 5, 6), these profiles are provided on one side with protruding hook ribs 23b and on the opposite side with hook protrusions 23g. On the side with the hooking ribs 23b, a covering profile 23i can be snapped on by means of hooking ribs 23a or it can be adhered, using the rib 23c that forms a stop and a possible profile 8a, a panel 8 of different material . On the opposite side, on the other hand, the hooking ribs 23a of a metal covering profile 23e are hooked on the hooking projections 23g; Alternatively, a metal or plastic profile 24 can alternatively be snapped into the hooking projections 23g to which a panel 9 can be adhered in a different way and of a different material. Said profile 24 makes it possible to compensate for the loads that appear due to the different thermal expansion between the profile 23 of the frame and the panel 9 placed, and said profile 24 also prevents, in case of solar irradiation, excessive heating of the profile 23 located below.
