Description

The invention relates to a closure part for the lateral closure of a cover rail on a building projection below a window or a door and a cover rail, as described in the preambles of claims 1, 7, 8 and 13.

From the DE 73 17 198 U is a on a building projection below a window or a door mountable cover rail and a termination part for lateral closure of the cover rail is known. The cover rail is designed approximately Z-shaped and is made of metal, in particular aluminum, or plastic. The covering rail has a covering part lying on the building projection, a fixing leg projecting upwards from this and attachable to a window floor, and a eaves bar projecting downwardly therefrom and projecting on the building wall. The ends of the cover rail are provided with the end parts. Each end part comprises a perpendicular to the main plane of the cover rail extending end wall, a perpendicular thereto projecting Anputzschenkel and at least one parallel to the Anputzschenkel and against the cover part attachable support web. The final part is connected via a joint connection, in particular a weld with the cover rail. The Anputzschenkel is provided on its side facing away from the cover rail top along the angular edge with a notch, which forms a predetermined breaking point. For attaching a guide rail of a sunshade, two saw cuts spaced apart from one another across the width of the guide rail are made to the notch on the plaster leg and the section of the plaster leg lying between the two saw cuts is broken. When doing so, guide the saw blade at an angle to the end wall and always make sure that neither the support bar nor the end wall is damaged. Although the worker can very skillfully try not to damage the support bar and the end wall, but then can not be sure that the saw cut reaches to the notch and this completely cut. Thus, there is a fear that, after the breaking of the portion between the saw cuts in the notch at those ends facing the cut-out portion, a burr may be caused to obstruct the drainage of water accumulated in the notch and the water penetrates behind the end portion. If the saw cuts are carelessly attached, can at the End wall Querriefen arise over which in turn water penetrates behind the end part. Thus, consequential damage to the building wall is unavoidable. In addition, the attachment of the saw cuts is very time-consuming, so that the assembly work on the construction site are unnecessarily delayed.

The object of the invention is to provide a closure part that can be quickly prepared on the construction site by a less experienced worker with a few simple steps for mounting on a cover rail and prevents the ingress of water into the building wall. The final part should be suitable for use on a cover rail.

The object of the invention is solved by the features of claim 1 or 8. It is advantageous that the worker without cutting process and in a single operation with a pair of pliers particularly quickly break a section from the plastering (spanlos) to introduce into the thus created cutout (breakthrough) a guide rail, such as a sunscreen can. Due to the notches extending transversely to one another, predetermined breaking points are defined which delimit a section to be removed in the plastering limb, which can be broken by the working force with little effort. If the indentations are arranged on the underside of the plastering leg, there is also the advantage that an accumulation of water in the indentations or a drainage of water into the building wall is avoided.

Another advantage is the embodiment according to claim 2 or 8, since after the breaking out of a section of the plastering leg along the indentations in the final part of a cutout is created, in which a guide rail of a sunscreen (Raff store or blinds) can be passed and thus ensured in that rain or condensation water is guided by the guide rail onto the cover rail and no water penetrates into the building wall behind the end part.

According to the embodiment according to claim 3 or 9, the cutout created after the breakout of the section is formed in the depth only over a part of the leg width of the plastering leg and remains an edge web with a width. Thus, it is now possible that a sealing element, in particular a sealing tape, at least over the width of the remaining edge web can be arranged continuously on the plastering leg and over a width at the end wall and between opposite ends of the end part. As a result, a clean seal between the end part and the guide rail of a sunshade as well as between the end part and the building wall is achieved.

According to claim 4 or 10 of the plastering leg is provided on its upper or lower side with a plurality of second indentations as predetermined breaking points which are provided in the usual widths of the guide rails for the sun protection corresponding distances at which a portion of the plastering leg can be broken. The predetermined breaking points are thus arranged in the standard dimensions of sun protection guide rails corresponding intervals. The notches are formed over a section on the plastering leg, which corresponds to the maximum width of conventional sunshade guide rails and are arranged within this section of each other by a distance. Otherwise, the grid spacing of the predetermined breaking points can be defined by the fitting dimension of the closing part on the window or on the door and the width of the guide rail. So the end part can be used with all common window types and guide rails and easily adapted to different installation conditions.

Also, the embodiments according to claims 5 and 6 or 11 and 12_von advantage, since it is ensured that the breakout force required for breaking a portion of the plastering leg can be kept low and also the remaining portion of the plastering leg is not deformed.

The object of the invention is achieved by the features of claim 7 or 13. It is advantageous that the prefabricated final part can be finished on the construction site within a very short time and mounted on a cover rail.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation.

In the jointly described Fig. 1 and 2 is a window area with a window 1 with a frame 2 (window sill), guide rails 3 for a sunshade 4, one on a building projection 5 below the window 1 on the outside of a building wall 6 arranged cover rail 7 (outside window sill) and one on a building projection 8 below of the window 1 arranged on the inside of the building wall 6 cover rail 9 (inner window sill). The building wall 6 has shown embodiment, a masonry 10 and arranged on the outside of the masonry 10 thermal insulation 11. The thermal insulation 11 is formed by a full thermal insulation (thermal insulation composite system), glued in the insulation boards on the outer wall and then their surface facing away from the outer wall surface are thinly plastered. On the other hand, it is also possible that the thermal insulation 11 is formed by a mounted on the outer wall thermal protection. The window 1 is attached via mounting bracket 12 on the masonry 10.

In Fig. 1 the arranged on the outside of the building wall 6 cover 7 (outer window sill) is shown, which is designed in cross-section Z-shaped. It has a cover part 14 arranged on the building projection 5, in particular in an embedding 13, an attachment leg 15 projecting upwardly therefrom and attachable to the window frame 2, and a eaves web 16 projecting downwardly therefrom and projecting on the building wall 6. The cover rail 7 is formed as an extruded profile of aluminum, an aluminum alloy or other metal alloy, or plastic.

The cover rail 7 is provided at its ends laterally with a termination part 19, as shown in the following figures in different embodiments.

The profile-like end part 19 comprises one of the building wall 6 (FIG. Fig. 1 ) adjacent, on projecting, strip-shaped end wall 20, one of these in the direction away from the building wall 6 direction and extending in the longitudinal direction of the end part 19, strip-shaped Anputzschenkel 21, a laterally projecting on the end wall 20 and extending in the longitudinal direction of the end part 19 supporting web 22 and a between the Anputzschenkel 21 and the support web 22 in the longitudinal direction of the end part 19 extending clamping web 23. The end wall 20 is provided at one of its ends with a diaphragm 24. The end part 19 is made of metal, for example as an extruded profile of aluminum, an aluminum alloy or another metal alloy, or of plastic.

The support web 22 has a channel section 25 in the form of a channel and on this projecting, parallel to the longitudinal extent of the end part 19 extending support portions 26, 27. The first support section 26 is formed by a raised on the support web 22 upwards in the direction of the plaster leg 21 elevation. The second support portion 27 is formed by an edge formed at an angle of 90 ° on the gutter section 25 upwards in the direction of the plaster leg 21. The channel section 25 is provided on the channel bottom with parallel to each other and in the longitudinal direction of the end part 19 extending grooves 28 which form raised and recessed areas. As a result, water can be specifically directed away from an end of the end part 19 facing the window 1 to an end of the end part 19 facing away from the window 1 via the channel section 25.

The clamping web 23 extends inclined in the direction of the support web 22, to the extent that a vertical distance 29 between a longitudinal edge 30, 31 at the free end of the clamping web 23 and the support portion 27 is dimensioned slightly smaller than a wall thickness 32 of the cover rail 7 (FIG. Fig. 8 ). If the end part 19 is mounted on the end of the cover rail 7, the lateral edge region of the cover part 14 is received between the support web 22 and the clamping web 23. The cover member 14 is applied via a force exerted by the clamping web 23 on it spring force with its underside against the support portions 26, 27. As a result, the closing part 19 is held solely by the spring action of the clamping web 23, therefore by frictional engagement on the cover rail 7. On the other hand, it is also possible that the cover rail 7 and the end part 19 are connected via a joint connection between the cover part 14 and the support web 22. The cover 14 is placed exclusively with its underside on the support web 22 on the support portions 26, 27. The clamping web 23 shown in the figures can be omitted.

As in the Fig. 3 to 7 can be seen, the Anputzschenkel 21 on one of the end wall 20 facing bottom 33 with at least one in the direction of a longitudinal extent the final part 19 extending, first notch 34 and one or more transverse thereto, second notch (s) 35 provided. Preferably, a plurality of second notches 35 are provided, as will be described in more detail below. The indentations 34, 35 form predetermined breaking points and are preferably produced by a machining process, for example grinding, sawing and the like. The second notches 35 extend perpendicular to the longitudinal extent of the plastering leg 21, with their ends terminating in the first notch 34. The indentations 34, 35 are each formed with a depth 36 which corresponds to at least half the wall thickness 37 of the plastering leg 21. For example, the depth 36 is between 50% and 75%, in particular between 55% and 65%, of the wall thickness 37 of the plastering limb 21. The notches 34, 35 have, starting from the bottom 33 in the direction of an upper side 38 inclined side edges 39 sloping towards one another , wherein the side edges 39 form an angle between 30 ° and 90 °, in particular between 50 ° and 70 °, for example 60 °.

As in Fig. 7 further registered, the first notch 34 at a distance 40 from one of the building wall 6 facing side surface 41 is arranged, wherein the distance 40 corresponds to at least one wall thickness 42 of the end wall 20. In a preferred variant, however, the distance 40 is greater than the wall thickness 42 and is for example between 2.5 mm and 10 mm, in particular between 4 mm and 8 mm. Thus, it is possible for a sealing element, in particular a sealing strip 43, to be folded around the angle edge extending between the end wall 20 and the plaster leg 21 in the longitudinal direction of the end part 19 and along the end part 19 with a width at the end wall 20 and with a width at the plaster leg 21 is appropriate, as in the Fig. 1 and 8th is apparent. A width 44 of the plastering leg 21 is between 10 mm and 55 mm, in particular between 25 mm and 35 mm.

As in the FIGS. 5 and 6 can be seen, at the bottom 33 of the Anputzschenkels 22 a plurality of arranged in a predetermined pitch 45 parallel second notches 35 are provided which form predetermined breaking points at which a portion 46 can be broken out of the Anputzschenkel 21. After breaking out, a breakthrough occurs, at which the guide rail 3 can be inserted. The grid spacing 45 of the second notches 35 is at different widths 47 of the usual on the market guide rails 3 (FIGS. Fig. 1 ) customized. The width 47 is between 15 mm and 120 mm, in particular between 20 mm and 105 mm. A depth 49 ( Fig. 8 ) of the guide rails 3 is between 20 mm and 55 mm.

The second notches 35 are arranged starting from one of the building wall 6, facing the first end of Anputzschenkels 21 in the direction of a facing away from the building wall 6, the second end of Anputzschenkels 21 over a stretch and corresponds to the distance between the first end adjacent left notch The left notch 35 'is 5 mm from the first end and the right notch 35 "is 150 mm from the first end, for example. The portion bounded by the second notches 35 ', 35 "and the first notch 34 extending therebetween can be easily broken out of the tap leg 21 at the construction site, and thus the length of the portion is defined by the second notches 35', 35" and the depth of the section defined by the first notch 34.

Is, however, as in Fig. 1 can be seen to mount a guide rail 3 with a smaller width 47, the between the left notch 35 'and between the left and right notches 35', 35 "provided central notch 35"'lying section is broken and the guide rail 3 between the remaining Sections of the plaster leg 21 introduced.

On the other hand, the grid spacing 45 can be defined by the predetermined breaking points to the mounting dimension 48 of the end part 19 on the window 1 and the width 47 of the guide rail 3, as in Fig. 5 inscribed in dotted lines. The mounting dimension 48 varies depending on different types of windows, and the termination portion 19 is disposed relative to the window 1 more or less deep below the frame 2, as in Fig. 2 entered.

In Fig. 4 a closure part 19 described above is shown, in which the plastering leg 21 is formed with a large width, for example 50 mm. The plaster leg 21 is bevelled at its end facing away from the building wall 6 end. Even if the Anputzschenkel 21 is formed with this width, after the notching of a portion 46, the guide rail 3 are inserted into the opening, wherein the longitudinal edge of the Anputzschenkels 21 flush with the outer contour of the guide rail 3 and the building wall 6 extends to the longitudinal edge of Anputzschenkels 21, as in Fig. 9 shown.

As a result, on the one hand it can be ensured that drainage from the guide rail 3 takes place directly on the cover rail 7 and, on the other hand, improved thermal insulation is achieved. After the guide rail 3 is completely disposed within the building wall 6, it is also no longer necessary that the guide rail 3 is provided over the entire length with a coating, in particular a coating, for optical purposes, but only in that, at the plastering thigh 21 in the direction of the cover rail 7 projecting end. After the guide rail 3 is approximately offset by the width 44 of the plaster leg 21 in the direction of the end wall 20, the distance between the end parts 19 (FIG. Fig. 2 ) And thus also the length of the cover rail 7 with respect to such systems known from the prior art, in which the guide rail rests against the longitudinal edge of the plaster leg 21, be significantly reduced.

Even if the plastering limb 21 is preferably provided on the underside 33 with the notches 34, 35, as described above, it would also be conceivable that the above-described and correspondingly formed notches 34, 35 are arranged on the upper side 38 of the plastering limb 21, such as in Fig. 10 shown.

The plastering leg 21 is provided on one of the end wall 38 facing away from the end wall 20 with one or more first notch (s) 34 extending in the direction of a longitudinal extent of the end part 19 and one or more second notch (s) 35 extending transversely thereto. Preferably, at the top 38 of the Anputzschenkels 22 a plurality of arranged at a predetermined pitch 45 parallel second notches 35 are provided which form predetermined breaking points at which a portion 46 can be broken out of the Anputzschenkel 21, as described above. After breaking out, a breakthrough occurs, at which the guide rail 3 can be inserted. The grid spacing 45 of the second notches 35, as described above, is based on different widths 47 of the guide rails 3 (common on the market) (FIGS. Fig. 1 ) customized. The width 47 is between 15 mm and 120 mm, in particular between 20 mm and 105 mm. A depth 49 ( Fig. 8 ) of the guide rails 3 is between 20 mm and 55 mm.

The indentations 34, 35 form predetermined breaking points and are preferably produced by a machining process, for example grinding, sawing and the like. The second notches 35 extend perpendicular to the longitudinal extent of the plastering leg 21, with their ends terminating in the first notch 34. The indentations 34, 35 are each formed with a depth 36 which corresponds to at least half the wall thickness 37 of the plastering leg 21. For example, the depth 36 is between 50% and 75%, in particular between 55% and 65%, of the wall thickness 37 of the plastering limb 21. The notches 34, 35 have, starting from the top 38 in the direction of the bottom 33, inclined side flanks 39 , wherein the side edges 39 form an angle between 30 ° and 90 °, in particular between 50 ° and 70 °, for example 60 °.

As in Fig. 10 further registered, the first notch 34 at a distance 40 from one of the building wall 6 facing side surface 41 is arranged, wherein the distance 40 corresponds to at least one wall thickness 42 of the end wall 20. In a preferred variant, however, the distance 40 is greater than the wall thickness 42 and is for example between 2.5 mm and 10 mm, in particular between 4 mm and 8 mm. Thus, it is possible for a sealing element, in particular a sealing strip 43, to be folded around the angle edge extending between the end wall 20 and the plaster leg 21 in the longitudinal direction of the end part 19 and along the end part 19 with a width at the end wall 20 and with a width at the plaster leg 21 is appropriate, as in the Fig. 1 and 8th is apparent.

The embodiments described above are not limited to the arrangement in a window area, but can just as well be used in a door area, for example a balcony door.

It is also possible that the first notch (s) 34 are arranged on the underside 33 of the plastering leg 21 and the second notch (s) 35 on the upper side 38 of the plastering leg 21, or vice versa.

The embodiments show possible embodiments of the end part 19, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this variation possibility due to the teaching of technical action representational invention in the skill of those skilled in this technical field. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

For the sake of order, it should finally be pointed out that, for a better understanding of the construction, end parts 19 of these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
