Description

The invention relates to a profile system and a method for producing a cuff window. The profile system comprising at least one frame profile, a sash profile, a forend basic profile and a face stamp profile, wherein the face plate base profile and the face stamp profile can be positively connected to each other.

Technical area

Stülpflügelfenster or Stulpfenster or doors are windows or doors with at least two wings without a vertical between the wings post. The first-to-open wing, also called the grand piano or the opening wing, strikes against the other wing, usually called the left wing, the ventilation wing, cuff wing or fixed wing, when it is closed. As far as simplified in the following and in the claims, the terms cuff window or Stulpflügelfenster are used, so are also sculptures or toadstool doors meant.

Usually plastic sash windows are made of standard hollow sections. At least in one of the wings must then disturbing the cuff area inside rollover, which serves as a stop on the frame in the areas outside the cuff area, are removed. This is associated with additional expense. In addition, the grooves or burrs resulting from removal of the profile stopper must be carefully removed and / or covered with a cover profile. Therefore, solutions with special forend basic profiles are already known.

State of the art

From the DE 101 55 475 A1 is a generic profile system for the production of a Stulpfensters known in which in addition to a standard sash profile a Stulp-base profile and a Faceplate blow bar profile can be used. The face stamp profile is positively connected to the forend profile, in addition, a screw connection of both profiles is required. Due to the use of very different cross-section sash frame and forend profiles, this construction requires a complex trimming and special closure caps in the miter compound area. Overall, the installation effort is considerable.

task

Object of the present invention is to provide a generic profile system for a sash window available, the production requires less effort.

Presentation of the invention

The invention achieves this object by a profile system according to claim 1, preferably in conjunction with one or more of the features of claims 2-4, and by a method according to claim 5.

The profile system according to the invention comprises, in addition to a window frame profile and a casement profile, a faceplate base profile and a face stamp profile, wherein the faceplate base profile and the face blow bar profile can be positively connected to each other. As a means for positive connection, the face-plate profile and the face-blow bar profile each have a connected state in operative connection with each other, having an undercut hook-shaped cam and together a pair of operatively connected to each other in the connected state locking connection means. The hook-shaped cams and the latching connection means are arranged spaced from each other, wherein in the region between the hook-shaped cams and the latching connection means in the connected state, a cavity for receiving adhesive is formed.

The frame profile, casement profile, forend profile and face stamp profile are preferably produced as hollow chamber profiles made of PVC-U by extrusion.

According to a preferred method, three sash profiles and one forend base profile are first cut mitred and welded together in the miter area to form a supernatant each in the upper and lower cuff area for the production of the passive leaf. The supernatant is removed by machining, in particular by milling or by suitable saw cuts. The resulting by the machining open face area of the sash profile can preferably be closed by means of a cap.

In the area between the hook-shaped cams and the latching connection means adhesive is applied to the forend base profile and / or the face stamp profile and latched the face stamp profile by means of a rotational movement with the forend basic profile, wherein the adhesive is pressed into the cavity and at least partially fills them.

The cuff-bar profile according to the invention and the cuff base profile are therefore connected to one another both by a bond and by a positive mechanical fastening. This leads both to a high mechanical stability and to a reliable sealing of the two profiles with each other and is also extremely efficient to assemble.

According to a preferred embodiment of the invention, the forend base profile and the face blow bar profile are connected to one another in a latching manner by means of a rotational movement.

The profile system according to the invention preferably has a cuff cap for closing the open ends of the cuff beater bar profile and a cover cap for closing the open end area of the casement profile.

According to a particularly preferred embodiment of the invention, the forend base profile and the sash profile have a substantially matching cross-sectional area. This ensures that the welding of these profiles in the miter area, the vast majority of the respective cross-sectional areas is welded together and an excellent cornering strength is achieved. The proportion of the welded surface is preferably more than 75%, particularly preferably more than 85% of the cross-sectional area of the forend basic profile.

The profile system according to the invention enables the rational production of both stop and center seal systems with very narrow view widths and high corner strengths.

Best way to carry out the invention

The canted window 1 shown in the drawing and the following explanation consists essentially of the frame of window frame profiles 2 and two wings, the in Fig. 1 and 3 on the left side, face-plate and the in Fig. 1 and 3 on the right shown walking or opening sash. The handle 13 ( Fig. 3 ) is used to open the walking or opening wing. All profiles used in this embodiment have been produced as hollow sections of PVC-U by extrusion. The cuff window 1 shown in this embodiment, as a center seal system with the center seal 11, 12, an outer stop seal and the inner stop seal 10 three sealing levels.

The average ( Fig. 3 ) Walking or opening wings shown on the right consists of four same, in the miter area welded together standard sash profiles 3 and has - as usual - a reinforcing chamber with inserted steel reinforcement 15 and inner glazing beads 16, which hold the glazing 14 together with the outer arcing 8 , The standard sash profiles 3 have a very low height, so that the sash window 1 shows extremely narrow view widths. The walking or opening wing has on all four sides of an inner wing flashover 29, which rests with the wing closed via an inner stop seal on the frame or on the stop surface 34 of the forend base profile 4.

The in Fig. 3 In contrast to the opening sash, the fixed leaf shown on the left is welded together from three standard sash profiles 3 and the forend basic profile 4. To do this first cut the forend base profile 4 and the sash profiles 3 mitred and - in the forend area at the top and bottom to form a supernatant 26 ( Fig. 4 ) - welded together. The inactive leaf points only to the in Fig. 3 left side and top and bottom of an inner wing flashover 29, which rests with the wing closed on an inner stop seal 10 on the frame, in the cuff area this attack on the frame but missing.

The projections 26 in the upper and lower cuff area are formed from the open miter ends of the inner wing flashover chambers 29 of the upper and lower horizontal sash profiles 3, since this inner wing flashover 29 is absent in the forend basic profile 4.

With the exception of the wing flashover chamber 29 and the immediately adjoining region between the fitting groove 27 and the inner visible surface and the hook-shaped cam 18 and the latching web 19, the cross-sectional areas of the forend base profile 4 and the sash profile 3 are largely identical, so that when welding these profiles in the miter area the majority of the cross-sectional area is also welded together. As a result, a high corner strength despite the narrow width of the profile profile is achieved.

After welding, the supernatants 26 are removed by machining, in particular by milling or corresponding saw cuts. The resulting by the milling 21 open end surface portions 33 are then closed by caps 7. In the FIGS. 5 and 6 is the upper cap 7 of in Fig. 3 shown on the left. The lower cap, not shown in the figures, has the same shape, but in a mirrored version.

In Fig. 7 is the face-plate profile 4 shown in cross-section. The outside is on the left, the room inside right. The outer flap 8 'corresponds in shape and Function the outer flap 8 of the sash profile 3 and holds together with the glazing bead 16 and the glazing gasket 9, the glazing 14, wherein in a conventional manner, the sash seal 17 thermally divides the Glasfalzbereich into two areas. The face plate base profile 4 has in many areas the same cross-section as the sash profile 3, in particular, the steel chamber for receiving the steel reinforcement 15 and the fitting groove 27 are identical in shape and location. However, the forend base profile 4 on the inside of the room lacks the inner wing flap 29; instead, a web extending parallel to the glazing 14 forms a stop surface 34 for the inner wing flap 29 of the in-wing flap 29 Fig. 3 right wing shown. The hook-shaped cam 18 of the forend base profile 4 corresponds to the corresponding hook-shaped cam 22 of the face-blow bar profile 5, so that both cams 18 and 22 engage one behind the other during assembly. Likewise, the snap-in web 19 of the forend base profile 4 corresponds to the projection 32 of the cuff-bar profile 5. Together, these snap-in bar 19 and the projection 32 form a latching connection.

The extending between the hook-shaped cam 22 and the projection 32 latching portion of the face-blow bar profile 5 corresponds in shape to the corresponding latching portion 20 between the hook-shaped cam 18 and the locking bar 19 of the forend basic profile 4, said areas through the small cam 35 of the forend Shock bar profile 5 is kept to form the cavity 31 at a small distance of a few tenths of a millimeter.

In the Fig. 7 - 9 the attachment of the forend bar profile 5 is shown on the already welded and milled passive leaf. First, a Klebraupe of commercial PVC adhesive 24 in the latching region 20 between the hook-shaped cam 18 and the latching web 19 of the forend base profile 4 ( Fig. 7 ) applied. The face stamp profile 5 is then - as in Fig. 9 illustrated in three phases - by means of a rotational movement with the forend basic profile 4 positive fit latching connected, wherein the adhesive 24, the cavity 31 largely fills. Due to the positive latching connection of forend rasp bar profile 5 and forend basic profile 4, the adhesive 24 can cure or dry at rest, without a screw connection would be mandatory. If necessary, however, the connection of the forend bar profile 5 with the forend basic profile 4 - as in Fig. 8 represented - additionally secured by one or more screws 25. The bonding of the forend base profile 4 with the face-blow bar profile 5 serves not only the permanently secure connection of these two profiles, but also the seal. To the outside, an additional seal 23 seals the gap between the forend base profile 4 and the forend blow strip profile 5 (FIG. Fig. 9 ).

In Fig. 10 is symbolically illustrated as the cuff caps 6 close the upper and lower open ends of the cuff bar profile 5. The cuff cap 6 has on its underside guide or clamping tongues which engage in the hollow chambers of the forehead blow bar profile 5. In addition, the screws 28 connect the cradles 6 with the forehead rasp profile. 5
