FRAMEWORK FOR DOORS AND WINDOWS OF SOLDABLE THERMOPLASTIC MATERIAL, WHICH 5 CAN BE COVERED WITH DIFFERENT MATERIAL

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

Profiles for the manufacture of frames for doors and windows are known which, using snap-in elements spaced apart from each other, fixed to said profiles, can be coated with metal profiles or with profiles of other materials. This system is frequently used, through the

15 external placement of aluminum profiles, as exterior protection against weather influences for wooden frames.

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

25 FR 2948719 is known sheet frames and fixed frames that can be coated with pressure-fitted profiles; these cover profiles being hooked, as individual pieces not joined together, to the frame with a longitudinal side and snapped into the second longitudinal side. This type of placement implies that the miter joints on the front side of the coating profiles, due to the different coefficients of thermal expansion between the frame, which is for example PVC, and the coating profiles, which for example are aluminum, they open in different sizes, in an unsightly way, or that deformations, tensions or also damage occur in corner areas. From DE 10059849 A1, fixing systems are known between a glass that protrudes with respect to the insulating glass glass running through the outer edge and a fixing element, or

35 adhesive element, inserted in the sheet frame. It is also known that in said fixing or adhesive element a flange is formed which covers the surrounding protruding edge of this glass pane, in relation to all or most of the thickness of the glass. The systems proposed in this document have the disadvantage that the dimensions of the glass crystal rarely fit exactly within the surrounding covering flange and that, therefore, an irregular, unattractive joint is generally visible between the edge of glass and coating flange.

Aluminum composite profiles with thermal bridge interruptions are also known through the interposition of anchored plastic elements, generally by

45 rolled in metal profiles. Under the requirement to improve thermal insulation, the plastic elements take considerable measures while the metal profiles have reduced cross sections.

The solutions mentioned above do not foresee that the profile that forms the frame itself can receive coatings of different materials on both sides, for example wood on the inner side directed towards the house and aluminum on the outer side exposed to meteorological influences. In addition, the known profiles that form the frame do not have, because they have a cross-section that is more or less reduced in the cross-section of the placed cladding profile, a structure that allows an effective anchoring of the fittings and guarantees

55 good thermal insulation, and these frames also do not offer high stability. In particular, profiles made from fiber reinforced plastic and aluminum composite profiles cannot be equipped with co-extruded gaskets, and welding is not common, which means that water can enter the corners of the frame and that the Gasket placement must be carried out at a later work stage and this occurs in the corner areas without packing continuity.

The profiles for the coating of the fixed frames and / or of the leaf frames are snapped into the frame, in known systems, such as individual pieces, cut to size to miter. This has as a consequence that, in particular due to the different coefficients of thermal expansion 65 of the material from which the frames are made and of the material from which the coating profiles are made, in the corner areas where the miter cut ends meet of the profiles

to the deformation of the coating profiles, to the snap fittings loosened or to be damaged.

5 The utility model DE7732328U shows frames, presenting the profiles on the side exposed to the meteorological influences of longitudinal hooking for the fixing of covering profiles, the covering profiles being joined by means of joining squares to form covering frames stable.

The invention aims to manufacture, by means of a single typology of thermoplastic plastic profiles, fixed and leaf frames for doors and windows of different construction characteristics, all of which have high thermal insulation, high shape stability, without use stiffening elements, a structure to which the hardware can be anchored effectively, and being also provided with co-extruded gaskets and being prepared to be able to

15 cover the frame on both sides comfortably with different materials, eliminating the problems of the different thermal expansion that appear in the case of frames with support function with coating of different materials. The invention also sets out the objective of designing said frames in the corner areas in an absolutely tight manner against the penetration of water in the profiles and of providing an effective evacuation of the water that has penetrated between the leaf frame and the fixed frame.

Another object of the invention is to cover, in the case of insulating glass crystals in which the outer glass forms, with respect to the other glass, an protruding edge and therefore completely covers the sheet frame, the corresponding surrounding edge with the thickness of this glass pane of the

25 as cleanly as possible by means of a corresponding profile, so that possible deviations from the dimensions cut to size can be compensated to achieve a surrounding coating without joints.

To solve this objective, the invention proposes a frame according to claim 1. The cross section of the profile of weldable thermoplastic plastic, for example of PVC, can be divided by several interior longitudinal walls to obtain a high number of chambers which, due to at the reduced distance of said walls from each other, they offer a multiple anchor for the fastening screws of the fittings. Said internal structure of the profiles, together with the protruding parts with respect to the configuration, in the case of a sheet, of the stop for the housing of the glass of 35 glass and / or of the stop acting on the fixed frame, or in the In the case of a fixed frame, of the outer stop against which the leaf frame rests in the closed position, they ensure in the corner areas an effective union 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. In addition, the profiles according to the invention, either on the inner side that is directed towards the housing, or on the outer side, are provided with protruding longitudinal ribs that are provided along the outermost protruding edge of a hitch boss . Said ribs with hitch projection are prepared for the sawtooth housing that protrude from the rear side of coating profiles, for example metal, which cover the entire interior or exterior surface of the frame profile. In the case of wood coatings or wood derivatives, they can be shaped

45 of slats and the longitudinal ribs that protrude from the frame profile have corresponding longitudinal grooves or in said covering strips, profiles or elements having elastic snap-in ribs that snap together behind the ribs of engagement in the ribs can be placed Longitudinal 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 means of 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 housing behind the placed coating.

55 The structure on both sides that can be covered in the frame profile is configured so that it has surfaces for the placement of glass panes or, for example in the case of door profiles, for the placement of metal panels or other materials, which they are placed in a plane parallel to the plane of the window glass, or that of the door leaf. In addition, the same grooves that are provided between the engagement 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 coating joints, for example between a glass pane and the frame. In the case of placing a glass pane instead of an inner liner, a known moisture absorbing distance element of the type for the manufacture of thermally insulated glass crystals is used in the intermediate space present. In this

In this case, the placed glass completely covers the frame of the sheet together with the surrounding gasket and gives the sheet an innovative appearance.

In this case, the snap-in profile is provided, for the adhesion, or fixation, of the covering profiles, with a toothed appendage to which a T-shaped profile is hooked in its cross section with a correspondingly serrated flange and thus can be pushed until it rests

5 fully on the outer edge of the glass pane, or also press on the corresponding gasket in the frame and partially cover it. In this way, a virtually seamless joint 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 difference in expansion between the frame and the covering, which, after their individual profiles have joined in the corner areas, has the shape of a frame, is effectively assumed and, in particular, partly due to the possible longitudinal displacement between the window or door frame and the cover frame, and partly because of the elasticity of the engagement ribs. In particular, the coating profiles or slats that are placed in the frame of

15 window or door on the side of the house are secured in their mounting position by means of the hardware fixing screws. In accordance with the invention, the longitudinal ribs are milled with the engagement projections in the profiles of the fixed frame and the leaf frame in the four corner areas of the frames to thereby offer the covering frame the possibility of be able to deviate in case of tensions between the sheet frame or the fixed frame and the corresponding cover frame, without these tensions leading to visible deformations or damage. The profiles that form the sheet frame and also those that form the corresponding fixed frame are joined in a known way, together with the extruded gaskets, by welding, whereby a tight structure appears against the penetration of water in the corner areas . Profile

25 of the lower horizontal leaf or door have a cross-section that, in the area directly inside the exterior stop conformation, provides a known channel for receiving 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 outside perforating the profile in the area of the lowest point of said channel, with a slight inclination outwards with respect to a vertical and perforating the same profile in the point corresponding to this first perforation from the outside horizontally, in the most tangent way possible with the inner surface of the bottom wall of the profile.

The invention is explained in more detail with the aid of some preferred embodiments, schematically represented in the accompanying drawings, of frames for doors and windows of

35 weldable thermoplastic material coated with different material; In this respect, the drawings have a purely explanatory purpose, not limitation.

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

Fig. 1a shows in detail the outer part of the fixed profile shown in Fig. 1 with the outer covering which is placed by adhesion on an intermediate profile fitted under pressure.

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

55 the details corresponding to the corner area of the inner cover frame and the leaf frame; In this respect, the covering frame is shown from the side of the connecting square and the leaf frame from the side of the longitudinal ribs with hitching.

Figure 2 shows in cross section the lower part of a window leaf frame, the frame being manufactured from a profile identical to that of Figure 1, but with a glass pane together with a moisture absorbing distance element, which is adhered to the outer side of the inner stop of the sheet by means of an intermediate profile in whose toothed appendix a correspondingly serrated flange of a T-shaped profile is inserted into its

65 cross section for the jointless coating of the outer edge of the glass pane.

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

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

Figure 4a shows the same window frame depicted in Figure 4, without glass

15 and without the corresponding frame, but with a triple insulating glass, covering the glass on the side of the house completely the top of the leaf frame and being adhered to an intermediate profile, snapped into the leaf frame; In this respect, the outer edge of this crystal, as also shown in Figure 2, is covered without joints by a T-shaped profile in its cross-section.

Figure 5 shows the horizontal cross section through a part of the leaf frame of a glass door and through the corresponding fixed frame, the leaf 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 composed of the same profile shown in Figure 5 and metal or non-metallic covering panels being placed on both sides; in this respect, the surrounding outer edge of the panel covering the top of the leaf frame is covered without joints by a T-shaped profile inserted in its cross section.

The profile 1a that forms the fixed frame of a window (figures 1 and 3) has on the inner side directed towards the housing some protruding longitudinal ribs 1b, spaced apart from each other, which have on the outermost free edge a hooking projection; 35 additional walls 1f may be provided between these ribs 1b which eventually form a closed chamber whose wall is aligned with the outermost edges of the engagement ribs 1b. Said ribs 1b can accommodate the ribs 10b that protrude from a metallic lining profile 10 or can be placed on the ribs 1b, after the removal of the walls 1f, directly a wooden strip 10h. Either the metal profile 10 or the wooden strip 10h also acts as a stop for the gasket 2y that protrudes from the window leaf. In the same area of the engagement ribs 1b, the profile 1a of the fixed frame 1 has several walls 1p on the inner side that are arranged close together to offer a multiple and efficient anchoring of the fixing screws 5 of the pernio. The screws 5a for fixing the closing fittings penetrate at least one of the ribs 1b and 1f, or the wooden strip 10h. On the outer side exposed to meteorological influences, the same profile 1a has two nerves of

45 hook 1c spaced apart from one another 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 joining brackets 10w, 10v, 10x to stably frame frames. The profile 1a also has, on the outer side, a vertical flange 1d in which an extruded gasket 1x is provided that acts outside on 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 has eventually penetrated between the sheet 2 and the fixed frame 1; said water can be evacuated through the perforations 6 outwards.

55 The profile 2a of the leaf frame 2 of a window is of the type with a heat insulating glass 7 adhered to the vertical wall 2f of the profile 2a. The same protruding part with said wall with adhesion surface is provided, on the side directed towards the housing, of two longitudinal engagement ribs 2b spaced apart from each other that can accommodate the corresponding engagement ribs 20a protruding from a metal covering profile 20 , the engagement ribs 3a of a metal profile

or of plastic 3 for the adhesion of a glass crystal 7a or the ribs 4a of an intermediate metal or plastic profile 4 that is fixed to a covering wood slat. Said glass crystal 7a may be adhered exclusively to the inwardly oriented surface of the rib 2c that forms the top of the sheet 2 or also on said intermediate profile 3; in any case, in the intermediate space that appears when the glass glass 7a is adhered, a spacer element of

65 known moisture absorption 70, 70a (Figure 2). The outermost longitudinal edges of said covering profiles 20, or the strip 20h, press against the gaskets 2z and 2y gasket 2y. The surrounding outer edge of the bonded glass 7a, 7c is coated without joints by a T-shaped profile 30 in its cross-section which engages with its serrated flange 30a in a correspondingly serrated appendix 3b of the intermediate profile 3. The same profile

image8

Intermediate 3 can also be placed on the outer side of the profile 1a of the frame 1 to enable the adhesion of coating profiles or covering panels 24 of different materials (Figure 1a), the same intermediate profile 3 can also be used snap-in on the inner side of the profile 2a of the sheet 2 for adhesion of coating elements 24 of different materials (Figure 2b).

10 Outwardly, the same profile 2a of the leaf 2 is provided with a coupling 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 7 glass glass placed. On the outer side, the profile 2a can also have two 2d coupling ribs parallel to each other, with a view to placing a profile

15 of metallic coating 20b (figure 3).

In the case of a sheet 2v composed of an inner frame with profiles 2i and an outer frame with profiles 2e, to be able to accommodate a Venetian blind in the interior space, the profiles 2i of the inner frame present, in the direction of the house, technical characteristics similar to those presented in profile 2a, for example, it can accommodate a metal coating 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 that forms the outer frame (figure 4) that is articulated to the inner frame 2i, with a view to its opening, is provided with a vertical wall 2g for the adhesion of the glass glass 7b and a groove in which it engages a corresponding 20s anchor shoulder

25 of a 20n metal coating profile.

According to the invention, the inner 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 housing, has a smooth surface that is situated in a plane parallel to the plane of the glass pane 7, to offer a support 30 for the coated 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 joining brackets 20w, 20v, 20u to form frames stably, while the engagement 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

35 are snapped for the adhesion of glass crystals 7a, 7c on the sheet frame and eventually have a serrated appendix 3b, they can be secured to the sheet frame 2a, 2v, for greater security, in the central area by at least a screw 3c.

In the case of 2t sheets, composed of profiles 23, of glass doors (figures 5, 6), these profiles

40 are provided on one side with projecting engagement ribs 23b and on the opposite side with coupling projections 23g. On the side with the engaging ribs 23b, a covering profile 23i can be snapped by means of hooking ribs 23a or it can be adhered, using the rib 23c which forms a stop and an eventual profile 8a, a panel 8 of different material . On the opposite side, on the other hand, the hooking ribs are engaged in the engagement projections 23g

45 23a of a metal coating profile 23e; on the same engagement projections 23g, a metal or plastic profile 24 can alternatively be snapped to which a panel 9 of different shape and of different material can be attached. Said profile 24 makes it possible to compensate 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 the case of solar irradiation, excessive heating of the

50 profile 23 located below.
