Description

Technical field

[0001] The invention relates to a sliding end piece for window sills according to the preamble of claim 1 and to a window sill mounting method according to the preamble of claim 12.

[0002] Special window sill end caps are required for metal or plastic exterior window sills. They form the transition between the side ends of the window sill and the window reveal. This transition should be aesthetically pleasing and create a secure connection to the window reveal. It is essential to prevent moisture from penetrating the plaster or masonry and to compensate for the thermal expansion of the window sill caused by temperature fluctuations. Because the window sill slides within the end caps to accommodate this expansion, these end caps are also known as sliding end pieces.

[0003] It is known to manufacture sliding end pieces as plastic parts or using the aluminum die-casting process. Furthermore, it is known to produce L-shaped sliding end pieces from a straight metal profile rail by forming, as disclosed in DE 102 50 781 A1. EP 2 116 684 B1 teaches an improved manufacturing process. Finally, the sealing of the sliding end pieces using EPDM sealing shoes has been successfully developed to prevent consequential damage from water ingress, even in the case of driving rain; see the product description "RBB Aluminium RAG" from the 2019 Bau trade fair exhibitor. 2 K".

[0004] Although such window sill finishes have proven practical, an alternative design is of interest. Description of the invention

[0005] The task remains to specify an alternative window sill mounting method that is as less complex as possible and does not lead to any adverse consequences with regard to airtightness.

[0006] This problem is solved by means of a sliding end piece according to claim 1 and a window sill mounting method according to claim 12, comprising the respective characterizing features.

[0007] Advantageous further developments are specified in the dependent claims and especially also in the description referring to figures.

Fig. 4a is intended to intervene, Fig. 4c a perspective view of the second profile element from Fig. 4b.

[0009] In Fig. Figure 1 shows three sliding end pieces 1, 1' according to a first embodiment of the sliding end pieces according to the invention, into which two window sills 2 are inserted.

[0010] The window sill 2 is designed to be installed in a window recess of a building or vehicle. Towards the building (not shown) or its window, a wall connection leg 26 is angled upwards, namely by an internal angle 21, often not quite 90°. Fig. In Figure 1a, a free rear corner 23 of the window sill 2 is visible at the top left, behind the sliding end piece 1 which is attached to the window sill 2 on the left. Towards the front, away from the building, the window sill 2 often slopes slightly downwards with a forward-sloping sill surface 24 and transitions into a final end leg 26, which is often angled downwards at a not quite 90° angle from a front upper edge 27. The end leg 26 has a lower edge 28 from which water running off the window sill drips away. The sides are usually sealed at the top towards the window sill, i.e., a seal of the sliding end piece is pressed down onto the window sill from above, or the window sill is inserted into a sealing shoe, as described in the prior art above and not shown here. One of the ideas underlying the invention rejects this approach of preventing water ingress at the top.

[0011] The sliding end piece 1, 1' is made from at least one first profile element 3, 3'. Its front region is also angled downwards. According to this preferred embodiment, the first profile element 3, 3' is designed as an upper part of a water-bearing receptacle for the window sill 2. It allows water to pass downwards from above, but limits the flow of water and thus protects the building from uncontrolled water ingress.

[0012] In Fig. 1a is only visible in the case of the sliding piece 1 shown on the right, the outer side connection 35.a that extends towards or connects to the building. Fig. In the case of the left sliding end piece 1 (without a window sill being shown), an inner side end 35.i of the left cover leg 31 of the first profile element 3 can be seen parallel to the concealed outer side end 35.a. A front leg 32 is angled downwards towards the front, terminating at the bottom with an outer drip edge 33. No further sealing is required at the rear, towards the wall connection leg 22, between an upper back edge 34 and the window sill, nor at any other intermediate element – ​​thus at a point where sealing is otherwise common.

[0013] According to the invention, the sliding end piece 1, 1' has at least one sealing device 14, 14' which rests against the window sill from below.

[0014] The sealing device 14, 14' extends to the illustrated embodiment of the Fig. 1b accordingly under the entire (not shown) window sill 2 sealing from the rear back leg 42 of a second profile element 4 forward to almost the end leg 26 of the window sill 2. In the illustration according to Fig. 1b shows the left sliding piece 1 without a window sill in perspective to allow some insight into preferred water-bearing designs, for example a forward-leading partition wall 45 and a less prominent forward-leading elevation 46.

[0015] The preferred design of the sealing device 14 according to Fig. Figure 1b schematically shows, without specifying a more precise sealing variant, a type of sealing lip profile on the top of an edge wall 43. The profile from the rear wall 42 to the inner drip edge 44 at the front is visible. This ensures a completely sealed contact of the window sill, preventing even sudden or sudden inflows of water from escaping laterally from the second profile element 4 into the building. Direction of water downwards and forwards is thus ensured.

[0016] According to this preferred embodiment, the edge wall 43 is shown as the right-hand side termination of the second profile element 4, which interacts with the first profile element 3. At its bottom, its lower leg 41 rests flat on the horizontal part of the window recess and projects slightly forward. At the rear, the back leg 42 of the second profile element 4 extends up to the rear edge 34 of the first profile element 3.

[0017] The left sliding end piece 1 is shown enlarged at position B according to the figure list above in a front view to allow a precise view. A comparison with the one in Fig. 2d analogously depicted sliding connector (a special case of a sliding end piece 1', namely for connecting two window sills). Whether from the right into the left sliding end piece 1 or from the left and right into the sliding end piece 1' designed as a sliding connector, in both cases rainwater must be drained onto the window sill 2 or window sills 2. Following the idea presented here and sketched with an exemplary embodiment, the water is not sealed at the top as usual, but is allowed and intended to enter the sliding end pieces. According to the preferred embodiment shown, it reliably encounters a respective bottom leg 41, 41' of the sliding end piece 1, 1'. At the rear, the bottom leg has a back leg 42, 42'. Otherwise, the bottom leg extends flat forward to the drip edge 44, 44'.

[0018] According to the advantageous embodiment shown, the first profile element 3, 3' can be closed from above with the bottom leg 41, 41 as a water-permeable closing element of the sliding end piece 1, 1' in such a way that the window sill 2 is mounted with lateral play between the bottom part 41 and the first profile element 3.

[0019] According to a further preferred embodiment of a sliding end piece 1, 1' according to the invention, at least one expansion sensor 12 is provided facing the window sill 2. In the preferred embodiment according to Fig. 3a, Fig. 3c and Fig.In the 3d embodiment, six spring-mounted expansion sensors 12 are attached to one side of the sliding end piece 1, 1'. At their other ends, the expansion sensors 12 extend freely inwards from the sliding end piece 1, 1' towards the windowsill 2. Thus, according to this embodiment, at least one expansion sensor 12 cushions the movement to compensate for thermal expansion. Contact with the windowsill 2 is therefore maintained in the sliding end piece 1, 1', even when the windowsill contracts in cold weather.

[0020] According to a further advantageous embodiment, the sliding end piece 1, 1' is made of at least two plastics of different hardness, preferably by means of coextrusion.

[0021] According to a further advantageous embodiment, the sliding end piece 1, 1' is designed with a sealing device 14, 14' as a co-extruded edge wall 43 with a sealing lip arranged towards the top.

[0022] According to a further advantageous embodiment, the sliding end piece 1, 1' is designed with guide channels 16, 16' running at least roughly parallel to the sealing device 14, 14' below the window sill 2.

[0023] According to a further advantageous embodiment, the sliding end piece 1, 1' in the case of at least two profile elements 3, 3', 4, 4' is held in an open position relative to each other in a mounting position for receiving at least one window sill 2, in particular in a first locking position, and the profile elements 3, 3', 4, 4' can be closed in a closed position after the window sill 2 has been inserted around the window sill 2, preferably in a non-destructively releasable manner.

[0024] According to a further advantageous embodiment, the sliding end piece 1' designed as a sliding connector 5' is designed for the water-carrying reception of two adjacent window sills, namely with a symmetrical structure with respect to a central plane that is oriented perpendicularly with respect to the window sill 2.

[0025] According to a further advantageous embodiment, such a sliding end piece 1', designed as a sliding inner piece or sliding connector 5', is configured with a downwardly oriented central web 51' for engagement with a bottom leg 41'. The bottom leg 41' has a sealing device 14' on both sides of a central web receptacle 52' designed to receive the central web 51' for each of the two window sills, as already described above as a sealing device in itself.

[0026] In conventional window sill installation methods, a sliding end piece 1, 1' is placed on each side of the window sill 2 before it is inserted into a window recess. The invention proposes inserting a first profile element 3, 3' on each side into a second profile element 4, 4' by a minimum amount, so that the respective end of the window sill can be placed onto the window sill 2 together. This is achieved in the present case by bringing a sealing device 14, 14' into contact with the window sill 2 from below.

[0027] According to a further advantageous embodiment, the connection between two window sills is not as shown, but, for example, at a right angle or at a different angle to the longitudinal extent of a window sill profile rail 1. A sliding end piece (not shown) for the angled wall connection or connection at a different angle to the next window sill is also to be covered by the patent.
