"Profile frames for sliding doors or windows

The innovation concerns a profile frame for sliding doors or windows, with at least one horizontal frame profile and at least one vertical frame profile connected to it via a corner connection.

To assemble a sliding sash or a frame for sliding doors or sliding windows , profile sections - hereinafter referred to as frame profiles - are mostly used . Preferably made from Alamiaiam Sr-estehan. As a rule, horizontal and vertical frame profiles are connected to one another in the corner areas of the frame. However, with sliding windows it is conceivable that the frame is not closed at the top, e.g. see the sliding window according to AT-PS 373 032 , in which the glass sliding sash is not framed in a horizontal profile on its top. A similar sliding window design is also described in DE utility model 84 30 411.

In general, the disadvantage of the known profile frames for sliding doors or windows is that the frame profiles form cold bridges if they are made of aluminum or a comparable heat-conducting material, which impairs the thermal insulation properties of the sliding window or sliding door. This disadvantage is particularly noticeable in the horizontal frame profiles of the sliding sashes, but less so in the vertical frame profiles, since when the sliding window or sliding door is closed, the sliding sashes overlap each other in the middle area of the door or window, where a seal is usually installed and thus a thermal insulation effect is achieved, and since in the area of the vertical frame profiles of the frame, a thermal insulation effect can be achieved by inserting seals and the like. It has now been proposed to achieve improved thermal insulation in the area of the horizontal frame profiles of sliding sash frames by using a multi-chamber construction or a composite construction. However, this makes the manufacture of the frame profiles extremely complex and expensive, although

For example, JP-OS 54-132 336 describes a technique in which two half profiles are connected to form a frame profile by keeping them at a fixed distance from each other and a casting material is introduced into the gap between them and hardened. This process is therefore relatively complicated and expensive.

A system with a heat-insulating coupling part that connects a gutter profile with a panel profile is also known from US-PS 4 117 640. The coupling part is elastically deformable in order to enable a type of snap connection with the profiles mentioned. However, such a construction system is clearly hardly sufficiently stable for the construction of profile frames for sliding doors or windows and is therefore not suitable.

-I Another problem with the profile frames in question here

The aim of this type is to create a corner connection that is as simple as possible and yet sufficiently stable. Usually, separate corner connecting elements are used for this purpose and an example of this is shown in EP-OS 164 479, but the corner connecting element disclosed therein is relatively complicated . Apart from ^that , the frame profiles here also have the thermal disadvantages mentioned above, just as with the frame system according to DE-OS 2 649 Cr21, where it is also disadvantageous that the interconnected profiles are inserted into one another, which prevents a flush finish.

The innovation is based on the task of creating a profile frame of the type mentioned above, in which on the one hand the disadvantageous cold bridges in the area of the horizontal frame profile(s) are avoided and excellent thermal insulation is achieved, while the construction and manufacture of these horizontal frame profiles and thus the profile frames are kept simple and cost-effective, and on the other hand, this design of the horizontal frame profiles also enables a simple but established connection of the vertical frame profiles in the back area. i| The innovative profile frame of the type mentioned above

that separate connecting blocks with corresponding longitudinal strips are inserted lengthwise into these half-profiles with longitudinal grooves or the like as thermal insulation material/ and that at least one of the connecting blocks is also provided as a corner connecting element for connecting the adjacent vertical frame profile and for this purpose is provided with

BXIIOIU nup^JLUil^DauDbiiiuki. Dbxi.iiasxi.xy auo uvm iivxiauiibaiou frame profile protrudes. The specified connecting blocks are preferably made of plastic, i.e. a heat-insulating material that can also be sufficiently rigid to fulfill the desired connecting function.

In the new design, the connecting blocks inserted at the front keep the two half profiles for the respective horizontal frame profile at a horizontal distance from each other, so that these half profiles do not touch each other directly. Accordingly, the two half profiles are thermally insulated from each other by the connecting blocks or by air, so that the undesirable cold bridges mentioned can be easily avoided. The design can also be made simple in that both half profiles belonging to the same frame can be formed by extruded profile sections of the same design, so that only one profile shape and one shape of connecting blocks are required; when assembling the respective horizontal frame profile, two half profiles are simply pushed onto the connecting block in a mirror-image arrangement (or the connecting block is pushed into them). With such a design, storage is therefore also simplified.

A further advantageous simplification of the design is then achieved by the fact that the connecting blocks are also used to connect the horizontal frame profiles with the adjacent vertical frame profiles. The vertical frame profiles are preferably essentially U-shaped in cross section.

For a stable anchoring, it has proven advantageous if the connecting blocks in cross section are

are essentially H-shaped, with the two vertical H-legs forming the longitudinal strips inserted into the half-profiles.

As can be seen from the above, the innovation is of particular importance for the construction of sliding sash frames for sliding doors or sliding windows, where no additional sealing measures are taken in the area of the horizontal frame profiles for improved thermal insulation and where cold bridges can be easily avoided by the new design. In the case of such a sliding sash, a particularly advantageous embodiment of the profile frame according to the innovation is further characterized in that the connecting blocks have a vertically extending slot recess for receiving a roller. With this design, the connection blocks also fulfil a third function, namely, in addition to the coupling of the two half-profiles with each other, with mutual thermal insulation, and the corner connection function, they also serve the function of supporting the rollers for the sliding sash, which can make the construction and assembly of sliding sashes even easier. tu*hot lot ea for a particularly simple, effective construction it is also advantageous if the connection blocks in the area of the slot recess are penetrated by a cross hole to accommodate an axle for the roller.

In the case of smaller, lighter sliding sashes, these are sometimes guided on lower running or sliding rails of the frame instead of on rollers, and in this case it is particularly advantageous if the connecting blocks are designed on their underside with a sliding surface 2Ur sliding guide of the sliding sash frame on a guide profile.

In this case too, the connecting blocks fulfil both the specified connecting functions and a guiding function.

For a particularly simple assembly of the profile frame, it is also advantageous if the coupling section has locking recesses in its side surfaces, preferably in the form of vertical locking grooves, which can be connected to the corresponding

Ratchet projections, particularly in the form of vertical strips, work together on the inner surfaces of the vertical frame profile. With this design, the vertical frame profiles are simply pushed or slammed onto the coupling sections protruding from the horizontal frame profiles until their locking projections engage in the locking recesses of the coupling sections.

In order to provide space in the vertical frame profile for any fittings etc., as well as to stabilize the corner connection and as an assembly aid to limit the sliding of the vertical frame profiles onto the coupling sections, it has also proven advantageous if the coupling section only extends to approximately half the depth of the vertical frame profile and in doing so abuts against a stop inside the vertical frame profile, which is preferably formed by strips protruding from the inner surfaces of the vertical frame profile.

It is further advantageous if a guide block, e.g. made of plastic, with at least one guide recess for guiding fittings, such as a locking slide, is inserted into the free cavity of the vertical frame profile in the corner connection area; this guide block can also advantageously form a stop for the coupling section of the connection block.

Finally, it is also advantageous if the coupling section at the transition to the rest of the connecting block forms at least one stop shoulder to limit the insertion depth in the half profiles.

The innovation is explained in more detail below using an example shown in the drawing in comparison to a known sliding window. The drawing shows in detail:

Fig. 9 shows the corner connection area of the profile frame in a representation similar to Fig. 8, now with the vertical frame profile completely folded onto the coupling section.

In Fig. 1, a double sliding window according to the prior art is illustrated in a schematic view, generally designated 1, wherein two glass sliding wings 2, 3 forming an inner window are visible, which are shown in the closed position in which they overlap one another, see also Fig. 2 and 3. In a similar way, the sliding window 1 shown according to Fig. 2 and 3 has an outer window formed by corresponding glass sliding wings 2', 3'.

The inner window of the double sliding window 1 shown in Fig. 1 is, like the outer window of the same, provided with a frame 4 or 4', which is formed by a lower profile guide rail 5 or 5', an upper profile guide rail 6 or 6' and vertical side profiles 7, ₃ or 8'. This frame is inserted in a window frame ff 9 under sealing, whereby the individual rails and H side profiles are screwed, for example, to the parts of the window frame 3 Fj with a seal 10 in between. According to

Fig. 3 also shows a drain plate 11. Fig. 1 also shows a handle 34 in the frame or edging profile 14 of the (inner) sliding window associated with the outer glass sliding sash 2 (a corresponding arrangement is also present in the outer sliding window with the glass sliding sashes 2', 3*). Furthermore, according to Figs. 1 to 3, the glass sliding sashes, namely the inner glass sliding sashes 3 and 3', are also associated with snap locks with a handle knob 38.

The lower guide rails 5 and 5' each have two j§

upright, rounded-top guide webs 12, 13 and 12', 13' fj, respectively, and the respective &psgr;

Glass sliding sashes 2, 3 or 2', 3' with lower, horizontal edging or frame profiles 14, 15 or 14', 15', which are, for example, anodized aluminum profiles. On their upper side, the glass sliding sashes 2, 3 or 2', 3' are guided in i channels of the upper guide rails 6 or 6' under sealing, as can be seen in particular from Fig. 3. The edging profiles 14, 15 or | 14', 15', which are essentially H-shaped in cross-section, are provided at the lower ends of their legs with seals, e.g. 16, which rest on the sides of the guide rails 12, 13 or 12', 13'. Sliding blocks, e.g. 17, are inserted into the edging profiles, e.g. 15, at least in the area of their inner ends, i.e. in the overlap area of the glass sliding panels, from the front sides, with which the glass sliding panels, e.g. 3, slide on the respective guide web, e.g. 13, and are thus slidably mounted.

To avoid cold bridges in the area of the vertical profile parts, it is possible to allow the glass panels of the glass sliding sashes 2, 3 or 2', 3' to protrude in the area of the vertical side profiles 7, 8 or 7', 8' and to seal them there with the help of seals 18 inserted in these side profiles, see Fig. In the overlap or middle area of the glass sliding sashes 2, 3 or 2', 3', for example, a brush seal 20 can be provided in the area of vertical frame profiles 19 (see also Fig. 2). However, the - here lower - horizontal

Frame profiles or edging profiles 14, 15 or 14', 15', whereby these cold bridges are formed by the webs 23 (Fig. 3) of these horizontal frame profiles 14, 15 or 14', 15'. Figs. 4, 8 and 9 illustrate a design of the horizontal frame profiles in which these cold bridges are avoided, whereby for the sake of simplicity in these figures, in which only a sash area of a sliding sash profile frame is illustrated, the glass panel of the sliding sash has been omitted. Figs. 5, 6 and 7 also illustrate the connecting block used in this design in a view, top view and side view.

From Fig. 4 it can be seen that two separate half profiles 31, 32 are used to obtain, for example, a lower horizontal frame profile 33. The half profiles 31, 32 have, for example, an identical cross-sectional shape, but are arranged as a mirror image of each other and are connected at least at the ends by connecting blocks 34 (in Fig. 4 only one end region is shown with a connecting block 34) and are kept at a distance from each other, see also Fig. 8 and 9, so that they do not directly touch each other.

Each half profile, e.g. half profile 31, has a lower angle flange 35 and an angle flange 36 provided in the upper third of its height, whereby these two angle flanges 35, 36 define an undercut groove 37 into which the connecting block 34, which is essentially H-shaped in cross section (see also Fig. 7), is inserted with a lengthwise line, namely one of its vertical legs 38 and 39, respectively. In the web 40 of the connecting block 34, an elongated slot recess 41 is also provided, see Fig. 4 and, for example, Fig. 6, and this slot recess 41 serves to accommodate a roller 42 (which has been omitted in Fig. 4 for the sake of simplicity); This roller 42 is mounted on an axle 43, which is shown schematically in Fig. 6 and 7, and which is simply inserted into a transverse bore 44 (see Fig. 4) passing through the connecting block 34, whereby it is in the assembled state of the half-profiles 31, 32 and the

connecting block 34 is prevented from falling out of the transverse bore 44 by these half profiles 31, 32.

The connecting block 34 is recessed up to stop shoulders 45 on the top and bottom of its legs 38, 39 (see also Fig. 4 and in particular Fig. 5), _with these stop shoulders 45 forming a transition to a coupling section 46 of the connecting block 34 which, in the assembled state , projects beyond the half-profiles 31, 32. This coupling section 46 serves to connect the horizontal frame profile 33 to an adjacent vertical frame profile 47 (see also Fig. 4 and Figs. 5 and 9). This vertical frame profile 47 is designed as a frame profile. is actually U-shaped in cross-section and has projecting, right-angled strips 50 around the inner surfaces of its legs 48, 49, which form a stop for the coupling section 46 of the connecting part 34, see in particular Fig. 8 and 9. At a distance in front of these strips 50, which act as a stop, sawtooth-shaped locking projections in the form of vertical strips 51 are provided on the inner surfaces of the legs 48, 49 in cross-section, which, when the vertical frame profile 47 is pushed or struck onto the connecting block 34 in the direction of the arrow in Fig. 8, lock into corresponding locking recesses in the form of vertical locking grooves 52 in the outer surfaces of the legs 38, 39 of the connecting block 34, in order to thus couple the connecting block 34 and thus the horizontal frame profile 33 with the vertical frame profile 47 in the manner of a locking or snap connection to be achieved.

In the assembled state illustrated in Fig. 9, the connecting block 34 with a coupling section 46 extends approximately half the depth of the vertical frame profile 47, whereby in the remaining cavity of the vertical frame profile 47, for example at the lower end of the same, a guide block 53 can be frictionally inserted, which ends flush with the strips SO on its front side and thus also functions as a stop for the coupling section 46 of the connecting block 34. In this essentially cuboid-shaped guide block 53, a - here, for example, circular in cross section - guide recess 54 is provided for

Guideway of a fitting part, such as a locking push rod 55 shown in Fig. 4, is provided.

In practice, as shown in Fig. 8, the horizontal frame profile 33 with the two half profiles 31, 32 and the connecting blocks 34 inserted at the front can be pre-assembled in the factory. Then, if necessary on site, the profile frame can be assembled by hitting the vertical frame profiles 47 onto the respective coupling section 46 of the connecting blocks 34 (while inserting the glass panel between the half profiles 31, 32, which is not further illustrated), see Fig. 9. The vertical frame profile 47 together with the already inserted guide block 53 and the fittings 54 guided therein can also already form a pre-assembled structural unit. j If the innovation is described above using a particularly

\ preferred embodiment has been explained, ^it is of course possible to make a variety of variations and modifications within the scope of the innovation. For example,

It is conceivable not to equip the connecting block 34 with a roller 42 and instead to design its underside as a sliding surface for I a sliding guide, similar to the case with the f sliding blocks 17 according to Fig. 3. The half profiles 31, &igr; can also, as shown in Fig. 4, be attached to the lower

Angle flanges 35 have lateral insertion grooves 56 on the inside for receiving seals such as the seals 16 according to Fig. 3. It would then be conceivable to omit the fitting guide 53, 54 and to provide the vertical frame profiles 47 with shorter legs 48, 49, whereby the coupling sections 46 could then reach up to the web of the vertical frame profiles 47. For additional fixing of the frame profiles to the connecting block 34, screws can also be used, but this is

considered less advantageous because of the additional work required.
