Description

[0001] The invention relates to a sealing arrangement with a sealing profile for watertight sealing of a connection area between a window sill and a window frame and with at least one sealing element.

[0002] Window sills on the exterior of a facade primarily serve as weather protection, in addition to their aesthetic appeal. To ensure controlled drainage of precipitation from the facade and prevent water from entering the building, the window sill must be properly connected to adjacent structural elements, such as the window frame or reveal.

[0003] To connect to the window frame, window sills typically have a window sill flange, also known as a raised edge, which is designed to be screwed to a frame flange of the window frame. The frame flange is often located on a window sill connection profile of the window frame, which can also be referred to as a screw-on or base profile. The window sill connection profile forms a lower doubling of the actual frame profile of the window frame.

[0004] To ensure a watertight seal of the connection, pre-compressed sealing tapes are known from the state of the art and are arranged between the window sill flange and the frame flange.

[0005] From DE 197 23 487 C1 a threshold cover in the form of an angle profile with a first leg and a second leg is known.

[0006] From DE 10 2014 015 691 A1 a window sill device with a natural or artificial stone window sill and a fastening rail is known, wherein the fastening rail has two legs.

[0007] DE 20 2009 007 634 U1 discloses a window sill sealing system with a sealing membrane and a window sill seal.

[0008] A wall composite for metal window sills is known from EP 2 453 095 A2.

[0009] The object of the invention is to provide a sealing arrangement of the type mentioned at the outset which enables improved sealing of the connection area between the window sill and the window frame.

[0010] This object is achieved by providing a sealing arrangement having the features of claim 1.

[0011] The sealing profile of the sealing arrangement according to the invention is provided for the watertight sealing of a connection area between a window sill with a window sill flange and a window frame with a frame flange. The sealing profile extends longitudinally along a longitudinal axis and has a first profile leg and a second profile leg. The first profile leg is designed to be arranged between the window sill flange and the frame flange and has a front sealing surface with respect to a transverse axis and a rear sealing surface opposite the front sealing surface. The front sealing surface is designed to form a sealing contact with the window sill flange. The rear sealing surface is designed to form a sealing contact with the frame flange.The second profile leg protrudes forward from the first profile leg along the transverse axis and has an upper side located at the top with respect to a vertical axis and a lower side opposite the upper side. The upper side of the second profile leg is designed to form a sealing contact with an underside of the window frame. The underside of the second profile leg is designed to form a sealing contact with an upper end of the window sill flange. The solution according to the invention achieves improved sealing of the connection area. For this purpose, the sealing profile is designed to form several sealing contacts with different locations in the connection area. The first profile leg serves to directly seal the connection between the window sill flange and the frame flange.The second profile leg, which is connected to the first profile leg, provides additional sealing in the area of the underside of the window frame and in the area of the upper end of the window sill flange. The upper side of the second profile leg serves to seal against the underside of the window frame. The underside of the second profile leg seals against the upper end of the window sill flange. These two sealing contacts of the second profile leg prevent water from entering via the underside of the window frame and / or the upper end of the window sill flange. The first profile leg has the front sealing surface and the rear sealing surface to form the respective sealing contact. In different designs, the second profile leg is designed in different ways to form the respective sealing contacts with the upper end of the window sill flange and the underside of the window frame.In one embodiment, the upper side of the second profile leg has at least one sealing surface for this purpose. In a further embodiment, alternatively or additionally at least one sealing lip is present. The same applies, mutatis mutandis, to the underside of the second profile leg. Preferably, the sealing profile is made of an elastic material, in particular an elastomeric plastic. The window sill to be sealed is a window sill for the outside of a facade, i.e. an external window sill. The window sill to be sealed is preferably made of metal, in particular aluminum. The longitudinal axis, the transverse axis and the vertical axis of the sealing profile form an orthogonal axis system. The directional and positional designations used in this description refer to a typical installation position of the window sill and thus also of the sealing profile.In this usual installation position, the longitudinal axis and the transverse axis extend in a horizontal plane and the vertical axis extends in a vertical plane. The longitudinal axis is aligned parallel to a longitudinal axis of the window sill and thus to a width of the window in question. The transverse axis is aligned in the depth direction of the window sill. In relation to the transverse axis, forward means outwards or towards the outside of the facade. In relation to the transverse axis, backward means towards the interior of the building. In relation to the longitudinal axis, outwards means facing the relevant reveal and inwards means facing away from the reveal.

[0012] In an embodiment of the invention, the upper side of the second profile leg has a form-fitting element which extends longitudinally along the longitudinal axis and projects upwards with respect to the vertical axis, and which is designed for a form-fitting connection with a frame groove recessed into the underside of the window frame. The form-fitting element serves for a form-fitting connection with the frame groove of the window frame. The form-fitting connectability of the sealing profile to the window frame allows for simplified installation of the sealing profile. In conventional window frames, the said frame groove is recessed into the underside of the window frame, in particular the frame profile. The frame groove preferably extends over the entire length of the window frame running along the longitudinal axis. The form-fitting element is preferably extended longitudinally over the entire length of the second profile leg and / or the sealing profile.To achieve a reliable positive connection, the design of the form-locking element is coordinated with the shape and / or dimensions of the frame groove. To create a positive connection, the form-locking element can be pressed, inserted, and / or snapped into the frame groove along the vertical axis from bottom to top. In an alternative design, a double-sided adhesive tape is provided instead of the form-locking element, which is adhered to the top side of the second profile leg. To connect the sealing profile to the window frame, the double-sided adhesive tape can be adhered to its underside. The side of the double-sided adhesive tape intended for bonding to the window frame can be covered with a removable protective film.

[0013] In a further embodiment of the invention, the upper side of the second profile leg has a sealing lip which extends longitudinally along the longitudinal axis and which is designed to form the sealing contact with the underside of the window frame. The sealing lip allows reliable sealing against the underside of the window frame. The sealing lip is preferably longitudinally extended over the entire length of the second profile leg and / or the sealing profile. If the window frame to be sealed has a frame groove recessed into its underside, the sealing lip contacts the underside of the window frame preferably along the transverse axis in front of the frame groove. If the second profile leg has a form-locking element, the sealing lip is preferably positioned along the transverse axis in front of the form-locking element.

[0014] In a further embodiment of the invention, the sealing lip forms a front end of the second profile leg with respect to the transverse axis. This seals the second profile leg, and thus the sealing profile, in a simple and effective manner against water ingress via the front end of the second profile leg.

[0015] In a further embodiment of the invention, the underside of the second profile leg has a receiving groove which extends longitudinally along the longitudinal axis and is recessed upwards into the underside of the second profile leg with respect to the vertical axis, and which is designed to sealingly receive the upper end of the window sill flange. When the sealing profile is installed, the receiving groove and the upper end of the window sill flange are plugged together. When plugged in, the upper end of the window sill flange is tightly received in the receiving groove. This simply and effectively prevents water from entering via the upper end of the window sill flange. Furthermore, this simplifies the installation of the sealing profile. The receiving groove is preferably longitudinally extended over the entire length of the second profile leg and / or the sealing profile.

[0016] In a further embodiment of the invention, the receiving groove forms a rear end of the second profile leg with respect to the transverse axis. This results in a simplified construction of the sealing profile.

[0017] In a further embodiment of the invention, the sealing profile is extruded from at least one elastomeric plastic. In principle, any elastomeric plastic suitable for the present application as a sealing profile is suitable. Such plastics are known to those skilled in the art. Ethylene propylene diene rubber (EPDM) has proven particularly advantageous.

[0018] In a further embodiment of the invention, the sealing profile is co-extruded from a first elastomeric plastic with a first hardness and a second elastomeric plastic with a lower second hardness, in particular wherein the second elastomeric plastic forms the form-fitting element and / or the sealing lip and / or the receiving groove. By coextruding from elastomeric plastics of different hardnesses, the sealing profile can be adapted in terms of its properties in certain areas to the primary function in the respective area. Preferably, the elastomeric plastic with a lower hardness is used to extrude the form-fitting element and / or the sealing lip and / or the receiving groove. As a result, the said functional elements and / or sections can be designed to be comparatively more flexible. This benefits the sealing function.Preferably, the first elastomeric plastic and the second elastomeric plastic are each an ethylene-propylene-diene rubber. The first hardness is preferably from 50 to 70 Shore, preferably 60 Shore. More preferably, the second hardness is from 30 to 50 Shore, preferably 40 Shore.

[0019] The sealing element of the sealing arrangement according to the invention is designed for arrangement in a corner region between the window frame, the windowsill, and a reveal. The sealing element according to the invention has a cap section and a base section. The base section has an inner side located in relation to the longitudinal axis and an outer side opposite the inner side. The inner side of the base section is designed to bear against an outer side of a sliding closure arranged between the front end of the windowsill and the reveal. The outer side of the base section is designed to bear against the reveal. The cap section projects inward along the longitudinal axis from the inner side of the base section and has an upper sealing surface with respect to the vertical axis and a lower sealing surface opposite the upper sealing surface.The upper sealing surface is designed to form a sealing contact with the underside of the second profile leg. The lower sealing surface is designed to form a sealing contact with an upper side of the sliding closure. The sealing element of the sealing arrangement according to the invention allows for improved sealing of the said corner area between the window frame, the window sill, and the reveal. In this corner area, a so-called service hole is usually present. If no special precautions are taken, precipitation can enter the building structure through the service hole. The sealing element of the sealing arrangement according to the invention allows for uncomplicated and reliable sealing of the service hole. In the assembled state, the base section of the sealing element is arranged between the outer side of the sliding closure and the reveal with respect to the longitudinal axis.The sliding closure is a component known to those skilled in the art for compensating for heat-induced changes in the length of the window sill in relation to the reveal. When assembled, the cap portion of the sealing element is positioned, relative to the vertical axis, between the top side of the sliding closure and the underside of the second profile leg, and thus also the underside of the window frame. The upper sealing surface of the cap portion forms a sealing contact with the underside of the second profile leg. The lower sealing surface of the cap portion forms a sealing contact with the top side of said sliding closure. The sealing element is preferably made of an elastic material, for example an elastomeric plastic. The sealing arrangement preferably comprises the sealing element and a further sealing element.The additional sealing element is designed to be arranged in a further corner area opposite the corner area along the longitudinal axis between the window frame, the window sill and the opposite side of the reveal.

[0020] In a further embodiment of the invention, the lower sealing surface of the cap section has a projection that projects downward relative to the vertical axis and is designed to engage over a front end of the upper side of the sliding closure located inward relative to the longitudinal axis. This projection allows for simplified positioning of the sealing element during assembly. Furthermore, the projection allows for improved sealing against the upper side of the sliding closure.

[0021] In a further embodiment of the invention, the lower sealing surface of the cap section is inclined forward with respect to the transverse axis, with the inclination being between 2° and 10°, preferably between 4° and 8°, particularly preferably 5°. When properly installed, window sills are usually installed with a gradient towards the outside of the facade so that precipitation can run off the front of the window sill. Accordingly, the sliding closure attached to the front end of the window sill also has a corresponding gradient. The inclination of the lower sealing surface of the cap section therefore corresponds to the installation gradient of the window sill / sliding closure. This ensures that the sealing contact between the lower sealing surface and the top side of the sliding closure is as full-surface as possible.

[0022] In a further embodiment of the invention, the sealing element is designed as an end cap and is configured for axial attachment to a rear end of the sliding closure. Compared to the sealing element according to the preceding embodiments, the end cap allows for simplified assembly of the sealing arrangement by the end user. In particular, processing errors are avoided. The aforementioned advantages arise from the axial attachment of the end cap. Preferably, the end cap is already attached to the rear end of the sliding closure during production. Preferably, the end cap is designed such that, when attached, a positive fit with the rear end of the sliding closure results.

[0023] In a further embodiment of the invention, the end cap has a base section which lies opposite the cap section with respect to the vertical axis and has a wraparound portion which is designed to be pushed axially onto a profile leg of the sliding closure. The base section and the cap section lie opposite one another along the vertical axis, wherein the base section, when the sealing arrangement is in the assembled state, faces a parapet of the respective window opening and thus faces away from the window sill. The rear end of the sliding closure lies between the cap section and the base section of the end cap with respect to the vertical axis. The wraparound portion of the base section is designed to be pushed axially onto said profile leg of the sliding closure. The wraparound portion is preferably U-shaped in cross-section.

[0024] In a further embodiment of the invention, the end cap has a rear wall section with an inner side and an axially opposite outer side, wherein the inner side rests against a rear end of the sliding closure and / or the window sill flange when plugged in, and wherein the outer side of the rear wall section rests against the front sealing surface of the first profile leg of the sealing profile. In the assembled state, the rear wall section therefore lies in the longitudinal direction of the sliding closure - and thus along the transverse axis - between the front sealing surface of the first profile leg of the sealing profile and the rear end of the sliding closure. In a further embodiment of the invention, the sealing element is made of an elastomeric plastic. Ethylene propylene diene rubber has proven particularly advantageous.

[0025] The invention also relates to a component arrangement comprising a window frame, a window sill, at least one sliding closure, a reveal and a sealing arrangement according to the preceding description.

[0026] Further advantages and features of the invention emerge from the claims and from the following description of preferred embodiments of the invention, which are illustrated with reference to the drawings.

[0027] According to the Fig. 1 to 4 A window frame 400 is inserted into a reveal 600 of a building facade (without reference symbol). The window frame 400 is firmly connected to the reveal 600 in a manner known to those skilled in the art and supports a pivoting window sash F, into which a window pane S is inserted. A window sill 300 is connected to the window frame 400. The window sill 300, more precisely: external window sill, is elongated along a longitudinal axis X and is connected to the reveal 600 at its opposite ends by means of a sliding closure 500. The sliding closures 500 serve to compensate for changes in length and have a design and function known to those skilled in the art.

[0028] For watertight sealing of the connection area between the window sill 300 and the window frame 400, a sealing profile 100 is provided (see Fig. 4 , 5). The sealing profile 100 is a component of a sealing arrangement 1. The sealing arrangement 1 comprises the said sealing profile 100 and at least one sealing element 200 (see Fig. 4 , 6 to 10 ).

[0029] The sealing profile 100 is elongated along a longitudinal axis X. In the assembled state of the sealing profile 100, the longitudinal axis X is parallel to the longitudinal extent of the window sill 300. The sealing profile 100 has a first profile leg 101 and a second profile leg 102.

[0030] The first profile leg 101 is arranged in the assembled state between a window sill flange 301 of the window sill 300 and a frame flange 401 of the window frame 400 (see Fig. 4 ).

[0031] The window sill flange 301 is arranged at a rear end of the window sill 300 with respect to a transverse axis Y and is also referred to as an upstand. The frame flange 401 serves to fasten the window sill flange 301, whereby in this case, a fastening by means of screws (not shown in detail in the figures) is provided. The window sill flange 301 and the frame flange 401 are extended longitudinally in the usual manner over the entire length of the window sill 300 and the window frame 400, respectively, extending along the longitudinal axis X.

[0032] In the embodiment shown, the frame flange 401 is arranged on a window sill connection profile 403 of the window frame 400. The window sill connection profile 403 is connected to an (actual) frame profile 402 of the window frame 400 in a manner not shown in detail. For example, the window sill connection profile 403 can be screwed or latched to the frame profile 402.

[0033] The first profile leg 101 has a front sealing surface 103 and a rear sealing surface 104 with respect to the transverse axis Y. The rear sealing surface 104 is opposite the front sealing surface 103 with respect to the transverse axis Y. In the assembled state, the front sealing surface 103 forms a sealing contact with the window sill flange 301. The rear sealing surface 104 forms a sealing contact with the frame flange 401.

[0034] The second profile leg 102 protrudes forward from the first profile leg 101 along the transverse axis Y and has an upper side 105 and a lower side 106 located at the top with respect to a vertical axis Z. The lower side 106 is opposite the upper side 105 with respect to the vertical axis Z. The upper side 105 of the second profile leg 102 serves to seal against a lower side 405 of the window frame 400. The lower side 106 of the second profile leg 102 serves to seal against an upper end 3011 of the window sill flange 301.

[0035] The said underside 405 of the window frame 400 is arranged on the (actual) frame profile 402 of the window frame 400. The underside 403 points downward with respect to the vertical axis Z. The underside 405 of the frame profile 402 is located above the frame flange 401 with respect to the vertical axis Z.

[0036] The first profile leg 101 and the second profile leg 102 are each longitudinally extended along the longitudinal axis X and parallel. In the embodiment shown, the first profile leg 101 is in cross section (see Fig. 4 , 5 ) extends along the vertical axis Z and is thus oriented vertically. The second profile leg 102 extends in cross-section along the transverse axis Y and is thus oriented horizontally.

[0037] The first profile leg 101 is longitudinally extended in cross-section between a lower end 107 with respect to the vertical axis Z and an upper end 108. The second profile leg 102 is longitudinally extended in cross-section along the transverse axis Y between a rear end 109 and a front end 110.

[0038] In the present case, the upper end 108 of the first profile leg 101 and the rear end 109 of the second profile leg 102 coincide. In other words, the second profile leg 102 protrudes from the upper end 108 of the first profile leg 101. As a result, the sealing profile 100 in the embodiment shown has an approximately L-shaped cross-section.

[0039] In this case, the first profile leg 101 has a flat cross-section and thus has a belt or band shape. The same applies analogously to the second profile leg 102.

[0040] In order to enable a simple and reliable connection of the sealing profile 100 with the window frame 400, the second profile leg 102 has a form-locking element 111 (see Fig. 5 ). The form-locking element 111 projects upwards along the vertical axis Z from the top side 105 of the second profile leg 102. The form-locking element 111 is designed for a form-locking connection with a frame groove 406 of the window frame 400. The frame groove 406 is recessed along the vertical axis Z from bottom to top into the underside 405 of the window frame 400, specifically the frame profile 402 of the window frame 400. The frame groove 405 extends in this case over the entire length of the window frame 400. When the sealing profile 100 is in the assembled state, the form-locking element 111 engages in the frame groove 406 in a form-locking manner. The said form-lock acts downwards along the vertical axis Z and forwards and backwards along the transverse axis Y.

[0041] In the embodiment shown, the form-locking element 111 has a head section 1111 and two strut sections 1112.

[0042] The head section 1111 is connected to the remaining sections of the second profile leg 102 by means of the two strut sections 1112. In the embodiment shown, the head section 1111 has a cross-section, ie in a YZ plane (see Fig. 5 ), has a triangular shape. The two lower corners of the triangular shape (without reference numerals) form undercuts that engage positively downwards along the vertical axis Z into the frame groove 406. Furthermore, the head section 1111 has a hollow chamber 1113, which is also triangular in shape and extends longitudinally over the entire length of the form-locking element 111.

[0043] The two strut sections 1112 are spaced apart from each other along the transverse axis Y. A further hollow chamber 1114, which has an approximately square cross-sectional shape, is arranged between the two strut sections 1112. The further hollow chamber 114 also extends longitudinally over the entire length of the form-locking element 111.

[0044] The form-locking element 1111 is longitudinally extended over an entire length of the second profile leg 102 and thus also over an entire length of the sealing profile 100.

[0045] In the embodiment shown, the upper side 105 of the second profile leg 102 also has a sealing lip 112. The sealing lip 112 is elongated along the longitudinal axis X and is designed to form a sealing contact with the underside 405 of the window frame 400. In the assembled state of the sealing profile 100, the sealing lip 112 lies tightly against the underside 405 of the window frame (see Fig. 4). In the present case, the sealing lip 112 extends longitudinally over the entire length of the second profile leg 102 and thus also of the sealing profile 100.

[0046] In the embodiment shown, the sealing lip 112 forms the said front end 110 of the second profile leg 102.

[0047] In the embodiment shown, the underside 106 of the second profile leg 102 has a receiving groove 113. The receiving groove 113 extends longitudinally along the longitudinal axis X and is recessed upwards into the underside 106 of the second profile leg 102 with respect to the vertical axis Z. When the sealing profile is in the assembled state, the receiving groove 113 is plugged together with the window sill flange 301, more precisely: its upper end 3011. The upper end 3011 is tightly received in the receiving groove 113. The upper end 3011 lies tightly against the receiving groove 113 on both sides with respect to the transverse axis Y.

[0048] In the present case, the receiving groove 113 forms the said rear end 109 of the second profile leg 102. In other words, the receiving groove 113 is arranged in the region of the upper end 108 of the first profile leg 101.

[0049] In this case, the form-locking element 111 is arranged between the sealing lip 112 and the receiving groove 113 with respect to the transverse axis Y. Starting from an imaginary center of the second profile leg 102, the form-locking element 111 is arranged along the transverse axis Y in the direction of the sealing lip 112 and thus offset forward.

[0050] In the embodiment shown, the rear sealing surface 104 of the first profile leg 101 has a plurality of projections 1041 positioned spaced apart from one another along the vertical axis Z. The projections 1041 serve to improve sealing against the frame flange 401. The projections 1041 can each also be referred to as a sealing lip.

[0051] In the present case, the rear end 109—and thus also the upper end 108—has a rear sealing lip 1091. The rear sealing lip 1091 rests against the frame flange 401 when the sealing profile 100 is in the assembled state. The rear sealing lip 1091 projects slightly rearward along the transverse axis Y beyond the rear sealing surface 104 of the first profile leg 101. In the embodiment shown, both the projections 1041 and the rear sealing lip 1091 extend longitudinally over the entire length of the sealing profile 100.

[0052] In the embodiment shown, the sealing profile 100 is made of different elastomeric plastics M1, M2, namely a first elastomeric plastic M1 and a second elastomeric plastic M2. Production takes place here by coextrusion. The first elastomeric plastic M1 has a first hardness. The second elastomeric plastic M2 has a comparatively lower second hardness. In the embodiment shown, the first hardness is 60 Shore and the second hardness is 40 Shore. The comparatively less hard elastomeric second plastic M2 is provided here for forming the receiving groove 113, the form-locking element 111, and the sealing lip 112. The comparatively harder first elastomeric plastic M1 forms the remaining sections of the sealing profile 100.

[0053] The sealing element 200 of the sealing arrangement 1 is in the assembled state in a corner area E (see Fig. 1 , 6 , 7) is arranged between the window frame 400, the window sill 300, and the reveal 600. The sealing element 200 serves to provide a watertight seal for the so-called access hole. If the access hole is missing or improperly sealed, water may enter the building structure. The sealing element 200 primarily prevents such water ingress through the access hole.

[0054] Furthermore, it is understood that the sealing arrangement 1 preferably has two sealing elements 200, each of which is arranged at corner regions opposite one another along the longitudinal axis X. In the present figures, only one sealing element 200 is shown.

[0055] The sealing element 200 has a cap section 201 and a foot section 202 (see Fig. 7 to 10 ).

[0056] The foot section 202 has an inner side 203 located inward with respect to the longitudinal axis X and an outer side 204. The outer side 204 lies opposite the inner side 203 along the longitudinal axis X. In the assembled state of the sealing element 200, the foot section 202 is arranged with respect to the longitudinal axis X between the reveal 600 and an outer side 501 of the sliding closure 500. The outer side 204 faces the reveal 600. The inner side 203 faces the outer side 501 of the sliding closure 500.

[0057] The cap section 201 protrudes inwardly from the inner side 203 of the base section 202 along the longitudinal axis X. The cap section 201 has an upper sealing surface 205 and a lower sealing surface 206 with respect to the vertical axis Z. The lower sealing surface 206 lies opposite the upper sealing surface 205 along the vertical axis Z. When the sealing element 200 and the sealing profile 100 are assembled, the upper sealing surface 205 forms a sealing contact with the underside 106 of the second profile leg 102. The lower sealing surface 206 forms a sealing contact with an upper side 502 of the sliding closure 500. In other words, in the assembled state, the cap section 201 is arranged between the upper side 502 of the sliding closure 500 and the underside 405 of the window frame 400 with respect to the vertical axis Z.

[0058] Fig. 4shows that the sealing element 200 is slightly wider than the sealing profile 100 with respect to the transverse axis Y. It is also understood that the sealing element 200 is significantly shorter than the sealing profile 100 with respect to the longitudinal axis X. The length of the sealing element 200 corresponds approximately to a width of the sliding closure 500 with respect to the longitudinal axis X. Further details of the sealing element 200 are described in the Fig. 8 to 10 shown.

[0059] In this case, the base section 202 has a rectangular basic shape. The thickness of the base section 202 relative to the longitudinal axis X is significantly smaller than its extension along the vertical axis Z and along the transverse axis Y. This results in a disc-like or plate-like shape of the base section 202.

[0060] The base section 202 extends along the vertical axis Z between a lower end 208 and an upper end 209. The cap section 201 is arranged approximately centrally between the lower end 208 and the upper end 209 with respect to the vertical axis Z. The base section 202 is oriented vertically in the assembled state. The cap section 201 is oriented horizontally.

[0061] In the embodiment shown, the cap portion 201 is approximately cuboid-shaped and extends between an outer end 210 and an inner end 211 with respect to the longitudinal axis X. The inner end 211 is positioned on the inner side 203 of the foot portion 202.

[0062] The lower sealing surface 206 of the cap section 201 has a projection 207. The projection 207 projects downwards from the lower sealing surface 206 along the vertical axis Z and is designed to engage over an inner end 5021 of the upper side 502 of the sliding closure 500 with respect to the longitudinal axis X (see Fig. 6 ). In the assembled state of the sealing element 200, the projection 207 projects inwardly and downwardly beyond the said end face 5021. The projection 207 is arranged at the inner end 211 of the cap portion 201.

[0063] As in the Figs. 9 and 10As shown, the lower sealing surface 206 of the cap section 201 is inclined forward with respect to the transverse axis Y. In this case, the inclination is 5°. Thus, the inclination of the lower sealing surface 206 corresponds to a typical installation slope of the window sill 300 and thus also of the sliding closure 500. In contrast, the upper sealing surface 205 is aligned parallel to a horizontal plane in the assembled state of the sealing element 200.

[0064] The window frame 400, the window sill 300, the sliding closure 500, the reveal 600 and the sealing arrangement 10 form a component arrangement 10 in the present case.

[0065] In the Fig. 11 to 13A sealing element 200a is shown, which can be used as an alternative to the sealing element 200 as shown in the preceding figures. In terms of its function and structure, the sealing element 200a is fundamentally very similar to the sealing element 200, so that, to avoid repetition, the following primarily focuses on the essential differences between the sealing element 200a and the sealing element 200. Components and / or sections of the sealing element 200a with identical functions are identified by identical reference numerals with the addition of the lowercase letter "a."

[0066] The sealing element 200a, in turn, has a cap section 201a and a base section 202a. The base section 202a has an inner side 203a located inward with respect to the longitudinal axis X and an outer side 204a. The cap section 201a protrudes inward along the longitudinal axis X from the inner side 203a of the base section 202a. Further in accordance with the sealing element 200 according to the preceding figures, the cap section 201a has an upper sealing surface 205a and a lower sealing surface 206a. Regarding the orientation and function of said sections and surfaces, what has already been disclosed for the sealing element 200 applies analogously.

[0067] In contrast to the sealing element 200, the sealing element 200a is designed as an end cap K. The end cap K can be axially attached to the rear end 503 of the sliding closure 500 along the transverse axis Y and thus in the axial direction of the latter. The attachment direction is in Fig. 11 marked with an arrow.

[0068] Preferably, the end cap K is already attached to the rear end 503 of the sliding closure 500 during production. When assembled by the end user, the sliding closure 500 is therefore already present with the end cap K attached. This prevents processing errors by the end user, which ultimately contributes to improved sealing of the corner area E.

[0069] In addition to the cap portion 201a and the foot portion 202a, the end cap K has a bottom portion 211a and a rear wall portion 212a.

[0070] The base portion 211a is opposite the cap portion 201a with respect to the vertical axis Z. In the attached state, the end cap K is held in a form-fitting manner at the rear end 503 along the vertical axis Z by means of the cap portion 201a and the base portion 211a.

[0071] In the embodiment shown, the base portion 211a has a wraparound portion 2011a, which is configured for axial sliding onto a profile leg of the sliding closure 500. The wraparound portion 2011a has a U-shape in cross-section, wherein the said profile leg of the sliding closure 500 is arranged and held in the plugged-on state between the opposing legs of the U-shape of the wraparound portion 2011a.

[0072] In the plugged-on state, the rear wall section 212a lies along the transverse axis Y - and thus in the longitudinal direction of the sliding closure 500 - between the first profile leg 101 of the sealing profile 100 and the rear end 503 of the sliding closure 500 (see Fig. 13 ). An outer side 214a of the rear wall section 212a rests against the front sealing surface 103 of the first profile leg 101 of the sealing profile 100. The inner side 213a (in Fig. 13shown in dashed lines) lies in a rear end face of the sliding closure 500.

[0073] The upper sealing surface 205a of the cap section 201a rests against the underside 106 of the second profile leg 102a.

[0074] The end cap K may have a support part 215a which is Fig. 13 is indicated by dashed lines. The support part 215a can, for example, be formed by a compressible material that can be glued to the cap section 201a. In this case, the upper sealing surface 205a is a surface of the support part 215a. By using the support part 215a, one and the same end cap K can be used for different sealing profiles with different dimensions and / or for different installation situations. The support part 215a can be glued to the end cap K by an end user.
