In order to make the installation of the edge lining in the window sill region and the assembly of the lining with window sills easier, the edge lining is designed in such a manner that the push-on member (10) is profiled in a U shape and has between its legs (13, 14) a lockable shaped part (12), and that the sill receiving slot (11) is present between this shaped part (12) and the inner surface (13') of one leg (13) of the push-on member (10). <IMAGE>

Description

The invention relates to an end edge cladding for thin window sills with a plastic push-on body which delimits a bank receiving slot, the push-on body being U-shaped and having a lockable molded part between its legs, and the bench receiving slot between this molded part and the inner surface of one Leg of the plug body is present.

The transition from window sills arranged in wall openings to the wall is often problematic. Conventionally, sealing is carried out with elastic joint sealing compound, which, however, is not durable and is destroyed in particular because of different thermal expansions of the window sill and the wall, so that water can penetrate into the wall. It has therefore become known to cover the edges of the window sills, namely with the plug-on bodies mentioned at the beginning, which take up the edges with their above-mentioned bank receiving slot. The bank slots can control the tolerances of the window sills caused by thermal expansion and the plug-on bodies can be sealed on or embedded in the wall without making significant movements and thus endangering the seal.

From DE-U-19 01 813 end edge clothing with the features mentioned above is already known. The known lockable molded parts are flat, curved, or angled leaf springs, which press the window sill upwards against the underside of the upper U-leg of the plug-on body. For the assembly of the lockable molded part with the push-on body, the molded part receiving leg must have a special receiving slot or some other design adapted to the shape of the molded part. Furthermore, the molding takes up the essential space between the U-legs, so that the upper U-leg can not be used as a cleaning stop. Ultimately, the known molded part must be assembled with the plug-on body prior to the installation of the window sill, which complicates the assembly of the clothing with the window sill, in particular if the latter cannot be inserted transversely to the clothing into the bank receiving slot.

In contrast, the object of the invention is to improve a push-on clothing with the features mentioned at the outset so that the installation of the end edge clothing in the window sill area and the assembly of the clothing with the window sills is facilitated.

This object is achieved in that the molded part has a U-shaped profile and is arranged with its bottom adjacent to the bottom of the U-shaped plug-on body.

If the molded part is profiled in a U-shape and its bottom is arranged adjacent to the bottom of the U-shaped plug-on body, the result is an expedient embodiment of the molded part in which an adjacent pair of legs of the plug-on body and the molded part of the latching and the other adjacent pair of legs of the plug-on body and of the molded part can serve to accommodate the window sill, the leg pairs being able to be adapted to the respective specific requirements. As a result of the U-shaped design of the molded part, the end edge clothing can be compared large dimensions can be produced with little material.

As a result of the configuration described above, the push-on body can be arranged, aligned and fastened in the region of the window reveal or the window sill without being assembled with the window sill. The plastering work, which may also serve to fasten the plug-on body, can already be carried out. Only then is the window sill installed and fastened to the push-on body by locking the molded part. For this purpose, the bank receiving slot is present between the molded part and the inner surface of one leg of the push-on body. The bench slot is open when the molded part is not installed and is therefore accessible for the installation of the window sill. In addition, the latching enables the windowsill to be removed again without any problem, without having to undo the attachment of the plug-on body on the wall. This is of advantage, for example, if the window sill has been damaged or if sealing work has to be carried out in the area between the window frame and the window reveal, which would interfere with a window sill. Ultimately, the molded part, which is separate from a plug-on body, gives the possibility of influencing the optical appearance of the end edge clothing as desired, for example by means of material or coloring in adaptation to the window sill and / or to the window frame. The molded part can be designed so that the plug-on body is completely covered from the visible side. The U-shaped profile of the plug-on body allows the molded part to be adapted to the various requirements of fastening, sealing and the appealing appearance.

The molded part is expediently latched to the inner surface of the leg of the plug-on body that is remote from the slot. The latching is then removed from the area of the bank receiving slot and, regardless of this, can be designed according to the latching requirements.

A locking between the plug-on body and the molded part which is easy to manufacture and satisfies the locking requirements is achieved in that the molded part has a longitudinal rib which engages in a longitudinal groove of the inner surface of the leg of the plug-on body remote from the slot.

The end edge cladding is designed in such a way that the molded part is supported on the inner surface of the slot-side leg of the plug-on body with a part of its outer circumference located at the bottom of the catch, and / or the catch is profiled like a sawtooth. Appropriate support of the molded part in the plug-on body stabilizes the positive connection of the two, although the latching is only present on one of their adjacent pairs of legs. In this way, the latching can be adapted to the latching requirements by sawtooth-like profiling. If the steeper sawtooth flank is arranged at the end of the leg, the molded part can be installed more easily than removed. In the opposite case, the arrangement of the steeper sawtooth flank can be achieved comparatively easily. This application is required if the molded part is comparatively stiff, but it cannot be removed.

If the attachments are attached to the window reveal before installing the window sill, care must be taken that the window sill can be inserted perpendicular to the wall after installation. For this purpose, it is necessary to provide the end edge clothing or its push-on body on the insertion side with corresponding insertion slots, which are undesirable, however, since they impair the appearance. As a result, the end edge clothing is designed in such a way that the legs of the plug-on body remote from the slot and, if necessary, of the molded part are made shorter than the legs on the bank-receiving slot side. In this case it is possible to avoid insertion slots. In addition, the window sill can be inserted into the plug-on body from above, ie vertically or with a vertical component. The extent of the shortening of the legs of the plug-on body and the molded part depends on the coverage of the bank edges by the receiving legs of the plug-on body and the molded part, which is necessary on the one hand for safe installation and on the other hand the different thermal expansions of the clothing and the window sill caused by temperature fluctuations to dominate.

It is advantageous for the end edge clothing that the slot-side leg of the U-shaped molded part is thinner than its other, serving the latching leg, which if necessary is provided with a flexibility point near the floor is. The thinner slot-side leg of the molded part makes it possible, particularly if the slot-side legs of the plug-on body and the molded part are longer than the slots away, to assemble the molded part with the plug-on body with less effort or deformation. If necessary, the assembly can be facilitated in that the leg serving for the locking is provided with the flexibility point, in order in this way to facilitate the compression of the locking.

In order to remove water from the latching area of the two main parts of the clothing, it is designed in such a way that the slot-side leg of the U-shaped plug-on body has a water drainage recess running lengthways. The lowest leg of the plug-on body is therefore used to effect drainage, which is possible without any problems since the clothing is known to be arranged obliquely downwards and outwards, so that water collecting in the recess is automatically removed from the area of the window reveal.

There is a bank stop surface vertical to the slot on the slot-side leg of the U-shaped plug-on body in the area between the bottom and the free end of its slot-facing leg. The bench stop surface serves to arrange the window sill in a structurally correct position between two push-on bodies opposite one another at the ends of the bench. As a result of the bench stop surface, the window sill cannot be installed so far towards a reveal wall of the window reveal that the opposite edge does not engage or does not engage sufficiently in the opposite plug-on body.

In order to prevent moisture from penetrating into the space located between the plug-on body and the molded part, for example due to water running off a soffit wall or due to driving rain, a seal is arranged on the slot-side leg of the U-shaped molded part on the slot side and on the slot-distant leg of the plug-on body on the molded part side. Such a seal is required, for example, if the space between the two main components of the clothing is not provided with a water drain, or if, for example, openings are present in the plug-on body which are connected to the reveal in a manner permitting water to pass through.

The end edge cladding is further designed so that the push-on body has an end wall arranged transversely to the molded part on the window side, which has at its upper edge at least in the area between the shortened and the unabridged adjacent legs of the push-on body and the molded part a bank-long edge insertion channel which is open at the bottom. With the insertion channel, the vertical upward-facing longitudinal edge of the window sill is gripped and prevents the edge of the bench from being unprotected or from getting behind the edge of the moisture, which, depending on the application of the end edge clothing, could be harmful. The insertion channel must be present at least in the longitudinal area of the clothing free of the window reveal, i.e. in the area of the overlapping of the neighboring legs forming the slot over the latching neighboring legs of the push-on body of the molded part, in particular if the molded part has a bench cover wall covering the bank edge.

To cover the frame-side corner area of the end edge cladding, it is designed such that the molded part is provided on the end wall side with a bench cover wall projecting from the slot-side leg to the lower edge of the insertion channel and integrally connected to the slot-distant leg. In particular, this covers the front edge of the window sill's bend adjacent to the frame, which also reduces the risk of contamination.

The invention is explained with reference to an embodiment shown in the drawing. It shows:

Fig. 2

a sectional view along the section line II-II of Figure 1 with the corresponding view of the window frame end region of the clothing perpendicular to the window frame plane.

The end edge clothing shown in FIGS. 1, 2 essentially consists of a plug-on body 10 and a molded part 12, which are assembled via a latch 18 and include a window sill 31 between them. This end edge cladding is installed in such a way that the push-on body 10 is fastened perpendicularly to the window plane on a window reveal wall 32 arranged transversely thereto, specifically in accordance with FIG. 1 with an inclination outward and downward. The attachment to the window reveal 32 is carried out in an adapted manner, e.g. by screwing the plug-on body 10 at the point 33 according to FIG. 2 if a fastening e.g. is provided on a plate or profile wall 34. However, it can also be plastered in and thereby fixed, the plug-on body 10 being able to determine the thickness of the plaster layer 35 above the window sill 31. In this case a screw connection is not necessary. The fixing can also be done with a double-sided sealing strip, which also serves to compensate for uneven walls.

From Fig.1 it can be seen that the end 36 of the end edge clothing remote from the window can protrude perpendicularly to the window frame plane over the outer wall 37 of the building and has a downward leg 36 ', which has a correspondingly vertically downward leg 31˝' of the window sill 31 on the end face disguised so that the end face is appropriately protected and has a handsome exterior. Furthermore, it can be seen from Fig.1 that the window-side end 38 of the clothing is provided with an end wall 26, which is provided on an upper edge 27 with a bank longitudinal edge insertion channel 28 to the top longitudinal edge 31 'of a vertical bend 31˝ of the window sill 37 to spread. The connecting wall 26 lies flat on the window frame 39 or a correspondingly arranged frame-parallel window reveal wall and is there in Sealed in the usual way, for example by a sealing strip or a conventional seal, so that the space 40 located under the end edge cladding above the horizontal reveal 41 is protected against moisture.

The plug-on body 10 is profiled in a U-shape according to FIG. 2 and accordingly has two legs 13, 14. The legs 13, 14 are arranged perpendicular to the window reveal and the bottom 17 of the plug-on body 10 connecting them to one another lies parallel to the window reveal, vertical to the frame plane 10, the representation plane of FIG. 2. A U-shaped molded part 12 is arranged between the legs 13, 14, the bottom 16 of which is closely adjacent and parallel to the bottom 17 of the plug-on body 10. This molded part 12 has legs 20, 21, which are each parallel and closely adjacent to the legs 13, 14 of the plug-on body 10, pointing in the same direction and thereby enclosing a material-free cross section 42 between them.

In order to be able to receive the edge 31 ^{IV of} the window sill 31 between them, the legs 13, 20 form a bank receiving slot 11 between their adjacent inner surfaces 13 'and 20'. This slot 11 is delimited in the plane of the window sill by a bench stop surface 24, which prevents insertion of the window sill 31 between the legs 13, 20 can lead to the window sill 31 coming out of the slot of the end edge cladding located at the other end of the window sill can slip out.

The leg 13 of the plug-on body 10 is provided with a longitudinal water drainage recess 23 which extends to the front end 36 of the plug-on body 10, so that penetrated into the slot 11 or into the space between the plug-on body 10 and the molded part 12 or there, for example water formed by condensation can run off. In order to seal the space located between the plug-on body 10 and the molded part 12, it is possible to provide seals 25. 2 shows a seal 25 which is between the leg 20 of the molded part 12 and the upper outer surface of the Windowsill 31 works. Such a seal 25 is glued into a correspondingly large recess in the leg 20, for example. A further seal 25 is present between the legs 14, 21 of the plug-on body 10 or of the molded part 12 and can be glued into a recess in the leg 14 to fix it.

The lower leg 20 of the molded part 12 is thinner than the lower leg 13 of the plug-on body 10. This is achieved by the recess shown in FIG. 2 in the slot-side inner surface 20 'of the leg 20 and this design serves to increase the leg 20 To give flexibility that is useful when the molded part 12 is assembled with the push-on body 10. This assembly also serves the latching 18, which is provided between the adjacent legs 14,21. Near the free edges in the leg 14, a longitudinal groove in the inner surface 14 'is attached, while the leg 21 has a longitudinal rib 15 which engages in the aforementioned longitudinal groove. The profile of the longitudinal rib 15 and the corresponding longitudinal groove is sawtooth-shaped, i.e. with a flank that is steeper than the other. The steeper flank is arranged near the free edge of the respective leg 14, 21 in order to make it more difficult to release the catch 18. In the leg 21 there is a flexibility point 22 near the bottom 16 in order to facilitate the rebound of the leg 21. This flexibility point 22 is achieved by flattening the outer surface of the leg 21 towards the bottom 16.

The support of the molded part 12 on the inner surface 13 'of the leg 13 takes place near the bottom 17 with a part 19 of its outer circumference, which is located in the area between the latching 18 and the bottom 17. As a result, the support of the molded part 12 on the plug-on body 10 is form-fitting and secure against relative tilting, which could otherwise lead to easier release of the latching 18.

It can also be seen from FIG. 2 that the neighboring legs 14, 21 are shorter than the neighboring legs 13, 20 of the plug-on body 10 or of the molded part 12. This serves to to be able to place the window sill 31 vertically from above and in front on the leg 13 when the molded part 12 has not yet been installed. With this installation, the upper edge 31 'of the vertical bend 31' of the window sill 31 is inserted into the trough 28 and thus hooked. As a result, it lies loosely on the leg 13, but cannot slide away from the window frame because the lower edge 29 overlaps the upper edge 31 '. It is possible to dimension the leg 21 longer than the leg 14 without thereby impairing the assembly of the molded part 12 with the plug-on body 10, the extension of the leg 21 being used to cover the free edge of the leg 14.

In order to finally secure the position of the window sill 31, the molded part 12 is installed between the legs 13, 14 of the push-on body 10 by first inserting the part 19 of the molded part 12 as far as possible between the legs 13, 14. In the process, the leg 20 of the molded part 12 deforms, which is designed to be flexible as described above. Subsequently, the leg 21 is pushed into the plug-on body 10 using the flexibility point 22 until the latching 18 engages. The assembly is now complete.

In the installed position of the molded part 12, the vertical edge 31˝ can also be covered by a bench cover wall 30 of the molded part 12, which connects the two legs 20, 21 on the window side and projects into the vicinity of the lower edge 29 of the insertion channel 28 according to FIG. As a result, the edge region of the window sill is shown in full dashed lines in FIG.

The window sill 31 is thin, so it consists of sheet metal, for example a sheet made of aluminum alloy. However, it is also possible to cover the end edges of plastic window sills in this way, which also solves the general problem of sealing the transition area between the window sill and the masonry against moisture.
