Support bracket for fixing a window sill and kit for creating different support brackets

Description

[0001] Window sill support brackets are used to fix window sills and typically consist of an angled mounting profile and a fixing profile connected to the mounting profile. The mounting profile is designed for attachment to the facade. The fixing profile provides direct support for the window sill and, when fixed, extends along one underside of the window sill.

[0002] From DE 20 2010 016 773 U1, a support bracket with an outwardly angled mounting profile is known. From DE 20 2018 105 411 U1, a support bracket with an inwardly angled mounting profile is known. The different known support brackets are intended for use in different installation situations on facades with different constructions, for example, on facades with and without external thermal insulation composite systems. Therefore, different support brackets are required for different installation situations.

[0003] DE202019104259U1 and KR102283312B1 also reveal a support bracket for fixing a window sill to a wall opening of a facade.

[0004] The object of the invention is to provide a support holder that offers advantages over the prior art. This object is achieved by providing a support holder with the features of claim 1.

[0005] A further object of the invention is to provide a kit that enables the formation of different support brackets for different installation situations. This object is achieved by providing a kit with the features of claim 19.

[0006] Advantageous further developments are specified in the dependent claims. The wording of the claims is incorporated by reference into the description.

[0007] The support bracket according to the invention is designed for fixing a window sill to a wall opening in a facade and comprises a fixing profile and a fastening profile. The fixing profile extends straight lengthwise and has a top surface which, when the window sill is fixed, extends lengthwise along a bottom surface of the window sill. In the fixed state, the bottom surface of the window sill rests on the top surface of the fixing profile and is thus supported by the fixing profile. The fastening profile is designed for attachment to the facade. For example, the fastening profile is designed for screwing and / or gluing to the facade. Nailing the fastening profile to the facade is also conceivable and possible.To form the aforementioned screw, adhesive, and / or nail connection, the fastening profile, in one embodiment, has corresponding screw, adhesive, and / or nail openings, each extending between a front and a back side of the fastening profile. The fastening profile has at least a first profile segment and a second profile segment. The first profile segment and the second profile segment are arranged in a row along the longitudinal direction of the fastening profile and are pivotally connected to each other about a hinge axis extending orthogonally to the longitudinal direction. In one embodiment, the hinge axis is formed by a solid-state hinge, which can, for example, be a film hinge and / or a cross-sectional reduction between the first and second profile segments. In another embodiment, the hinge axis is formed by a hinge with a hinge pin and a pin receptacle.Preferably, the first and second profile segments, as well as any further profile segments of the mounting profile, are integrally connected. The mounting profile has a back and an opposing front. The first and second profile segments each form a section of the back and a section of the front of the mounting profile. The back of the mounting profile is designed to rest against the facade. The front of the mounting profile has a longitudinally extending plug-in receptacle, which is designed to form a plug connection with the fixing profile. The plug-in receptacle therefore has a first plug-in section located on the first profile segment and a second plug-in section located on the second profile segment.Preferably, the plug-in receptacle consists of the first plug-in receptacle section and the second plug-in receptacle section. Preferably, the back of the mounting profile consists of the respective sections of the first profile segment and the second profile segment. The same applies, mutatis mutandis, to the front of the mounting profile. Preferably, the same applies if the mounting profile has more than two profile segments. Due to the design according to the invention, the mounting profile can be attached to the facade with the profile segments at different angles or with the profile segments at a fixed angle and plugged together with the fixing profile (and optionally a further profile of the support bracket). In this way, the support bracket can be adapted to different facade constructions and allows window sills to be fixed in different installation situations.This represents a significant simplification compared to prior art solutions, which require different support brackets for different installation situations. The articulated connection of the profile segments allows the mounting profile to be used in two configurations. In the first configuration, the profile segments are not angled relative to each other. In this case, the straight, longitudinally extended fixing profile can be connected to either the first or the second plug-in section. In the second configuration, the profile segments are angled relative to each other, for example, at approximately 90°. In this configuration, the fixing profile can be connected to either the first or the second plug-in section. It is understood that other configurations are conceivable and possible.

[0008] In this embodiment of the invention, the straight, longitudinally extending fixing profile is connected to the first and second plug-in receiving sections. This fixes the two profile segments in a straight, non-angled orientation relative to each other. Consequently, the fixing profile is straight in this embodiment. The rear side of the fixing profile is designed to rest on a horizontal reveal surface of the wall opening. This embodiment therefore provides for the fixing profile to be attached to the sill of the wall opening, more precisely to the horizontal reveal surface, which may be provided with a so-called insulating wedge. "Horizontal" means that the reveal surface is horizontal in the transverse direction of the wall opening. Naturally, a conventional outward slope can be provided in the depth direction to allow water to drain away.

[0009] In a further embodiment of the invention, the support bracket has a support profile. The support profile has a first profile leg and a second profile leg. The first profile leg and the second profile leg are angled relative to each other or can be angled. Preferably, the two profile legs are angled approximately at right angles to each other. In use, the first profile leg is preferably oriented vertically. The second profile leg is oriented horizontally or at least approximately horizontally. Approximately horizontal means that, when the support bracket is installed, the first profile leg may have a certain inclination, which allows for reliable drainage of water from the windowsill. The first profile leg is connected to the mounting profile's plug-in receptacle by forming a plug connection.Alternatively or additionally, a snap-fit ​​connection can be provided, in particular between a snap opening of the mounting profile and a complementary snap element of the support profile, specifically the first profile leg of the support profile, or vice versa. In one embodiment, the first profile leg is connected to the first plug-in receptacle of the first profile segment. In another embodiment, the first profile leg is connected to the second plug-in receptacle of the second profile segment. If the mounting profile has further profile segments, the first profile leg can alternatively be connected to another plug-in receptacle of a further profile segment. Alternatively or additionally, a snap-fit ​​connection can be provided with the first profile segment, the second profile segment, and / or the further profile segment. The second profile leg has a plug-in receptacle.In this embodiment, the fixing profile is connected to the plug-in receptacle of the second profile leg of the support profile via a plug connection. The plug-in receptacle of the second profile leg and the plug-in receptacle of the fastening profile each allow connection to the fixing profile. The two plug-in receptacles are therefore similar or identical in design. In one embodiment, the fixing profile is connected exclusively to the plug-in receptacle of the second profile leg. In another embodiment, the fixing profile is additionally connected to the plug-in receptacle of the fastening profile, for example, to the first plug-in receptacle section and / or the second plug-in receptacle section.

[0010] In a further embodiment of the invention, the first profile leg of the support profile is connected to the first insertion section of the first profile segment of the mounting profile. Alternatively or additionally, a snap-fit ​​connection may be provided. The second profile leg projects beyond the front of the mounting profile. In this embodiment, the profile segments of the mounting profile are not angled relative to each other. Consequently, the mounting profile extends straight along its length. This embodiment provides for the rear of the mounting profile to rest against a vertical facade surface below the wall opening. The rear of the mounting profile is designed accordingly. The vertical facade surface can be an external vertical facade surface, for example, the outer surface of a masonry wall or an external thermal insulation composite system.Depending on the facade construction, the exterior of the masonry may be covered only by exterior plaster or by the external thermal insulation composite system (ETICS). In this design, the fixing profile is not connected to the mounting profile's socket. The second leg of the profile projects beyond the front of the mounting profile. Preferably, the fixing profile projects beyond the back of the mounting profile.

[0011] In a further embodiment of the invention, the first profile leg is connected to the second insertion section of the second profile segment, and the second profile leg of the support profile projects beyond the front of the mounting profile. Alternatively or additionally, a snap-fit ​​connection may be provided. The profile segments are angled relative to each other, preferably by approximately 90°, more preferably between 90° and 98°, and particularly preferably 95°. In this embodiment, the fixing profile is connected to both the insertion section of the second profile leg of the support profile and the first insertion section of the first profile segment of the mounting profile. The two profile segments are fixed in their angled orientation by the insertion connection of the support profile to the mounting profile on the one hand, and by the insertion connections between the fixing profile and the support profile, and additionally to the mounting profile.This design provides that the back of the second mounting profile rests against a vertical facade surface below the wall opening. The back of the second profile segment is configured accordingly. The back of the first profile segment can either rest on a horizontal reveal surface of the wall opening or be positioned vertically above the horizontal reveal surface, creating a gap.

[0012] In a further embodiment of the invention, at least the first profile segment has opposing wing sections in the transverse direction of the mounting profile. A central section of the first profile segment is arranged between the wing sections. The two wing sections are each pivotally connected to the central section about a wing hinge axis extending longitudinally along the mounting profile, allowing for angular movement. Each wing section has a connecting section designed to form a positive-locking connection with a complementary connecting section of the second profile segment. This positive-locking connection stabilizes the angled orientation of the profile segments. The positive-locking connection can be formed when the wing sections are angled relative to the central section.Additionally, the first profile segment must be angled relative to the second profile segment. In this angled configuration of the mounting profile, the connecting sections of the wing segments can engage with the complementary connecting sections of the second profile segment to form a positive-locking connection. The wing hinge axes extend longitudinally along the mounting profile and preferably parallel to each other. More preferably, the wing hinge axes extend parallel to the longitudinal direction of the mounting profile. Regarding possible specific designs of the wing hinge axes, what has already been described for the hinge axis (solid hinge, film hinge, hinge, etc.) preferably applies, mutatis mutandis.

[0013] In a further embodiment of the invention, the wing sections are each angled towards each other relative to the central section and each projects beyond the rear side of the central section. Furthermore, in this embodiment, the first and second profile segments are angled relative to each other. The connecting sections of the wing sections and the complementary connecting sections of the second profile segment interlock to form a positive-locking connection.

[0014] In a further embodiment of the invention, the mounting profile has a third profile segment. The third profile segment is arranged on a side of the second profile segment opposite the first profile segment. The third profile segment is pivotally connected to the second profile segment about a further pivot axis oriented orthogonally to the longitudinal direction of the mounting profile. The third profile segment has a third insertion section corresponding to the insertion of the mounting profile. The third profile segment and its pivotal connection to the second profile segment enable even more versatile use of the mounting profile. In one embodiment, the third profile segment is not angled relative to the second profile segment. In another embodiment, the third profile segment is angled relative to the second profile segment.Regarding the design of the further joint axis, preferably and mutatis mutandis, what has already been described for the joint axis applies (solid-state hinge, film hinge, hinge, etc.). In this embodiment, the plug-in receptacle of the mounting profile is formed from the three plug-in receptacle sections of the three profile segments. In other words, the plug-in receptacle consists of the three plug-in receptacle sections.

[0015] In a further embodiment of the invention, the third profile segment is not angled relative to the second profile segment.

[0016] In a further embodiment of the invention, the first profile leg of the support profile is connected to the third insertion section of the third profile segment. Alternatively or additionally, a snap-fit ​​connection may be provided. The first and second profile segments are not angled relative to each other. The third profile segment is angled relative to the second profile segment. The fixing profile is connected to the first insertion section, the second insertion section, and the insertion section of the second profile leg. This embodiment provides that the rear side of the third profile leg rests against a vertical facade surface when installed. The rear sides of the first and second profile segments can rest on a horizontal reveal surface or be positioned vertically above the horizontal reveal surface, forming a gap.

[0017] In a further embodiment of the invention, the upper surface of the fixing profile has an adhesive strip designed to form an adhesive bond with the underside of the windowsill. The adhesive strip allows for reliable fixing of the windowsill. This adhesive bond prevents the windowsill from being lifted vertically, for example, by wind loads or the like. Preferably, the adhesive strip is covered by a removable protective film when delivered. The adhesive strip preferably extends longitudinally over the entire length of the upper surface. More preferably, the adhesive strip extends substantially over the entire width of the upper surface.

[0018] In a further embodiment of the invention, the support bracket has a hook section. The hook section comprises a first leg and a second leg. The first leg is designed to form a plug connection with a plug receptacle of the fixing profile that extends longitudinally along the fixing profile. The second leg is angled relative to the first leg and designed to hook into a support groove of the windowsill. The hook section allows for particularly reliable fixing of the windowsill. For this purpose, the second leg is hooked into the aforementioned support groove of the windowsill. The support groove is an upwardly open channel located at the lower edge of a wall apron of the windowsill, as is commonly found in exterior metal windowsills.The first and second hook leg sections are preferably angled approximately at right angles to each other. Preferably, the angle between the first and second hook leg sections is between 90° and 98°, particularly preferably 95°. In this embodiment, the fixing profile has the aforementioned longitudinally extending plug-in receptacle for connection to the hook section. The plug-in receptacle of the fixing profile extends longitudinally along the profile. The first hook leg section can be plugged into the plug-in receptacle of the fixing profile, forming a plug connection.

[0019] In a further embodiment of the invention, the mounting recess of the fixing profile has a receiving groove extending longitudinally along the fixing profile, which is designed to receive the first hook leg in a longitudinally displaceable manner. This longitudinally displaceable receiving of the first hook leg allows the position of the hook part to be easily adjusted to the site conditions during installation. Preferably, the receiving groove is located on the underside of the fixing profile. More preferably, the receiving groove extends longitudinally over the entire length of the underside of the fixing profile. Even more preferably, the receiving groove is formed by two opposing circumferential grips located in the transverse direction of the fixing profile, which are designed to grip opposing edge edges of the first hook leg.

[0020] In a further embodiment of the invention, the mounting profile's receptacle has a receiving groove extending longitudinally along the mounting profile, which is designed for the longitudinally displaceable reception of the fixing profile and / or the first profile leg of the support profile. The longitudinally displaceable reception of the fixing profile allows its position to be easily adjusted to the site conditions during installation. For example, the fixing profile can be positioned flush or protruding along the length of the receptacle. Preferably, the receiving groove of the mounting profile is formed by two opposing circumferential sections located transversely to the mounting profile. These circumferential sections are designed to grip opposing edge profiles. The same applies analogously to the reception of the first profile leg in the receiving groove.In this embodiment, the first profile segment has a first receiving groove section, and the second profile segment has a second receiving groove section. If the mounting profile has further profile segments, correspondingly more receiving groove sections are present. Preferably, the receiving groove consists of the receiving groove sections of the profile segments. If a snap-fit ​​connection is provided between the mounting profile and the first profile leg of the support profile, the mounting profile preferably has at least one snap opening, which is preferably arranged transversely between the aforementioned circumferential sections and is designed to engage with a complementary snap element of the first profile leg.Preferably, each profile segment of the fastening profile has at least one such locking opening, so that several locking openings are arranged distributed in the longitudinal direction of the fastening profile.

[0021] In a further embodiment of the invention, the insertion recess of the second profile leg of the support profile has a receiving groove extending longitudinally along the second profile leg, which is designed for the longitudinally displaceable reception of the fixing profile. The previously stated details regarding the longitudinally displaceable reception of the fixing profile apply. The receiving groove of the second profile leg is preferably formed by two opposite circumferential grips located in the transverse direction of the second profile leg. The circumferential grips are designed to engage opposite edge edges of the fixing profile.

[0022] In a further embodiment of the invention, the mounting profile is made of a plastic material. This embodiment allows for simple and cost-effective mass production. Compared to manufacturing from metal, improved thermal insulation is achieved and thermal bridges are avoided. Furthermore, the articulated connection between the individual profile segments of the mounting profile can be designed particularly simply when made from plastic. For example, the pivot axis—and optionally the other pivot axis and / or the wing pivot axes—of the mounting profile can be designed as a film hinge. Manufacturing by plastic injection molding is preferred.

[0023] In a further embodiment of the invention, the support profile is made of a plastic material. This allows for cost-effective production in large quantities. Compared to manufacturing from metal, improved thermal insulation is achieved and thermal bridges are avoided. Manufacturing by plastic injection molding is preferred.

[0024] In a further embodiment of the invention, the fixing profile is made of aluminum. Manufacturing it from aluminum ensures sufficiently stable support and fixation of the window sill. In combination with manufacturing the mounting profile and / or the support profile from plastic, thermal bridges are nevertheless avoided. Preferably, the fixing profile is manufactured by extrusion.

[0025] The kit according to the invention is designed for forming various support brackets and comprises a fixing profile, a support profile, and a fastening profile. The fixing profile extends straight along its length and has a top surface which, in a fixed state, extends along the underside of the windowsill and is designed to support the underside. The support profile has a first profile leg and a second profile leg, which is angled relative to the first profile leg and has a plug-in receptacle for forming a plug connection with the fixing profile. The fastening profile is designed for fastening to the facade and comprises at least a first profile segment and a second profile segment. The profile segments are arranged in a row along the longitudinal direction of the fastening profile and are pivotally connected to each other about a pivot axis extending orthogonally to the longitudinal direction.The profile segments each form a section of a rear side and a section of an opposing front side of the mounting profile. The rear side of the mounting profile is designed to rest against the facade. The front side of the mounting profile has a plug-in receptacle extending longitudinally along the profile. This plug-in receptacle is designed to form a plug connection with the fixing profile and / or the first leg of the support profile. The longitudinal plug-in receptacle of the mounting profile has a first plug-in section located on the first profile segment and a second plug-in section located on the second profile segment. The kit allows for the selective configuration of the support bracket and its various embodiments as described above.To avoid repetition, reference is made to the disclosure relating to the support holder according to the invention and its embodiments. What is disclosed therein also applies, mutatis mutandis, to the components of the kit according to the invention, i.e., the fixing profile of the kit, the support profile of the kit, and the fastening profile of the kit. In one embodiment, the kit has different fixing profiles with different overall lengths. Alternatively, a first embodiment of the kit has a fixing profile of a first overall length. A further embodiment of the kit has a second fixing profile with a second overall length.

[0026] In a further embodiment of the invention, the kit comprises a hook section with a first hook section leg and a second hook section leg. The first hook section leg is configured to form a plug connection with a plug receptacle of the fixing profile that extends longitudinally in the direction of the fixing profile. The second hook section leg is angled relative to the first hook section leg and configured to hook into a support groove of the windowsill. The hook section of the kit allows for particularly reliable fixing of the windowsill. To avoid repetition, reference is made to the disclosure relating to the hook section of the support bracket designed according to the invention. What is stated there applies, mutatis mutandis, to the hook section of the kit.

[0028] According to Fig. 1 A kit 2000 is provided for forming different support brackets 1, 1a, 1b, 1c, 1d. The different support brackets 1, 1a, 1b, 1c, 1d are intended for fixing a window sill 500 to a wall opening in a facade in different installation situations and are included together with the respective installation situation in the Fig. 3 bis 22 The different support brackets 1, 1a, 1b, 1c, 1d (and their variants 1', 1a', 1b', 1c', 1d') can be optionally configured using Kit 2000, depending on the on-site installation requirements for the window sill 500, as described in more detail below. The window sill 500 to be fixed is a weather-facing window sill (exterior window sill) made of metal, in particular aluminum.

[0029] Kit 2000 includes a mounting profile 100, a support profile 200, a fixing profile 300, and a hook part 400. The support profile 200 and the hook part 400 are optional and are not included with every support bracket 1, 1a, 1b, 1c, 1d.

[0030] The mounting profile 100 has a first profile segment 101 and a second profile segment 102. The mounting profile 100 is described in detail in Fig. 2 shown. In the embodiment shown, the fastening profile 100 also has an optional third profile segment 103.

[0031] Profile segments 101, 102, and 103 are arranged in a row along the longitudinal direction L1 of the mounting profile 100. The terms longitudinal direction and longitudinal axis are used synonymously in this description. The first mounting profile 101 and the second mounting profile 102 are connected to each other by a hinge joint G1, which extends orthogonally to the longitudinal direction L1 and is articulated. The second profile segment 102 and the third profile segment 103 are connected to each other by a hinge joint G2, which extends orthogonally to the longitudinal direction L1 and is articulated.

[0032] The mounting profile has a back side 104 and a front side 105. The profile segments 101, 102, 103 each form a section of the back side 104 and a section of the front side 105.

[0033] The rear side 104 of the mounting profile is designed for installation on the facade. The front side 105 of the mounting profile 100 has a longitudinally extending plug-in receptacle 106 in the longitudinal direction L1. Depending on the support bracket 1, 1a, 1b, 1c, 1d, the plug-in receptacle 106 can be connected to the support profile 200, the fixing profile 300, or the support profile 200 and the fixing profile 300.

[0034] The plug-in receptacle 106 has a first plug-in receptacle section 1061 arranged on the first profile segment 101, a second plug-in receptacle section 1062 arranged on the second profile segment 102 and in this case also a third plug-in receptacle section 1063, which is arranged on the optional third profile segment 103.

[0035] The support profile 200 has a first profile leg 201 and a second profile leg 202. The first profile leg 201 extends longitudinally along a longitudinal direction L21. The second profile leg 202 extends longitudinally along a longitudinal direction L22. In the Fig. 1 In the configuration shown, the support profile 200 is depicted in a non-angled state with its two profile legs 201, 202. The longitudinal directions L21, L22 are therefore coaxial. In the actual use of the support profile 200, and thus in the formed state of the support brackets 1a, 1b, 1c, 1d, the two profile legs 201, 202 are angled relative to each other (see in particular...). Fig. 7 , 11 , 15 , 19The two profile legs 201, 202 are angled approximately at right angles to each other. In this case, the profile legs 201, 202 form an angle of 85°. In one embodiment, the support profile is delivered in the flat configuration shown, and the profile legs are angled on-site. In another embodiment, the support profile is manufactured with the profile legs already angled.

[0036] The first profile leg can be connected to the plug-in receptacle 106 of the mounting profile 100, forming a plug connection. Depending on the installation situation and the support bracket to be formed, the first profile leg 201 can be connected to the first plug-in receptacle section 1061 (see Fig. 7 bis 10 ), the second plug-in section 1062 (see Fig. 11 bis 18 ) or the third plug-in section 1063 (see Fig. 19 bis 22 ).

[0037] The second profile leg 202 has a plug-in receptacle 206, which is designed to form a plug connection with the fixing profile 300.

[0038] The fixing profile 300 extends lengthwise in a straight line and has a top surface 301 and a bottom surface 302. When installed, the top surface 301 extends lengthwise parallel to a bottom surface 502 of the window sill 500, and the bottom surface 502 of the window sill 500 is supported on the top surface 301 of the fixing profile 300. The fixing profile 300 has a longitudinal axis L3.

[0039] In the illustrated embodiment, the fixing profile 300 also has a plug-in receptacle 306. The plug-in receptacle 306 is designed to form a plug connection with the hook part 400. In this case, the plug-in receptacle 306 of the fixing profile 300 is arranged on its underside 302.

[0040] The hook part 400 has a first hook leg 401 and a second hook leg 402. The first hook leg 401 extends longitudinally along a longitudinal axis L4. The second hook leg 402 is angled relative to the first hook leg 401. In this embodiment, the two hook legs 401, 402 are angled approximately at right angles to each other, with the angle between the hook legs 401, 402 being 95°. The first hook leg 401 is configured to form the aforementioned plug connection with the plug receptacle 306 of the fixing profile 300. The second hook leg 402 is configured to engage in a support groove 405 of the window sill 500 (see Fig. 4 , 8 , 12 , 16 , 20 ).

[0041] Before the individual support brackets 1, 1a, 1b, 1c, 1d (and their variants 1', 1a', 1b', 1c', 1d') formed using Kit 2000 are described in detail, further advantageous features of the fastening profile 100, the support profile 200, the fixing profile 300, and the hook part 400 according to the present embodiment of Kit 2000 will first be explained. The features associated with the specific embodiment are each advantageous, but not essential for the present invention.

[0042] The plug-in receptacle 106 of the mounting profile 100 is designed as a receiving groove 107. The receiving groove 107 allows for longitudinally displaceable mounting of the fixing profile 300 and / or the first profile leg 201 of the support profile 200. Corresponding to the plug-in receptacle 106, the receiving groove 107 is formed by individual sections of the profile segments 101, 102, 103. When plugged into the mounting profile 100, the fixing profile 300 is longitudinally displaceable along the receiving groove 107 and thus along the longitudinal axis L1.

[0043] In the illustrated embodiment, the receiving groove 107 has two opposite grips 108, 109 in the transverse direction Q1 of the fastening profile 100. The opposite grips 108, 109 can also be referred to as the first grip 108 and the second grip 109. The two grips 108, 109 are each designed to laterally grip the first profile leg 201 and / or the fixing profile 300.

[0044] In a state where the first profile leg 201 is joined together, the first circumferential grip 108 encompasses a first edge 204 and the second circumferential grip 109 encompasses an opposite edge 205 of the first profile leg 201.

[0045] In a state when connected to the fixing profile 300, the first grip 108 encompasses a first edge 304 of the fixing profile and the second grip 109 encompasses an opposite second edge 305 of the fixing profile.

[0046] The first circumscription 108 is formed by a first section 1081 of the first profile segment 101, a second section 1082 of the second profile segment, and a third section 1083 of the third profile segment. The second circumscription 109 is accordingly formed by a first section 1091 of the first profile segment 101, a second section 1092 of the second profile segment 102, and a third section 1093 of the third profile segment 103.

[0047] It is understood that the plug-in receptacle 106 may also be designed differently from the present design. This also applies to details of the design of the receptacle groove 107.

[0048] The insertion recess 206 of the support profile 200 is, in this case, a receiving groove 207 extending longitudinally along the longitudinal axis L22 of the second profile leg 202. Similar to the receiving groove 107 of the fastening profile 100, this groove is formed between the two grips 208 and 209 of the support profile 200, which are orthogonal to the longitudinal axis L22. The two grips 208 and 209 of the support profile 200 can also be referred to as the first grip 208 and the second grip 209. When connected to the fixing profile 300, the first grip 208 grips the first edge 304 and the second grip 209 grips the second edge 305 of the fixing profile 300. The fixing profile is longitudinally displaceable along the longitudinal axis L22 of the second profile leg 202.

[0049] The insertion recess 306 of the fixing profile 300 is, in this case, a receiving groove 307 extending longitudinally along the longitudinal axis L3 of the fixing profile 300. The receiving groove 307 is formed between the two grips 308 and 309 that are orthogonal to the longitudinal axis L3. The two grips 308 and 309 of the fixing profile 300 can also be referred to as the first grip 308 and the second grip 309. When connected to the hook part 400, the first grip 308 engages a first edge 404 and the second grip 309 engages an opposite second edge 405 of the first hook part leg 401. The first hook part leg 401 is longitudinally displaceable along the longitudinal axis L3 of the fixing profile 300.

[0050] Regarding possible alternative designs of the plug-in sockets 206, 306, what has already been said about the plug-in socket 106 applies accordingly.

[0051] In the illustrated embodiment, the mounting profile 100 is designed for screw fastening to the facade. Alternatively or additionally, an adhesive bond to the facade can also be provided.

[0052] For screw fastening, the fastening profile has several through holes 110 and several elongated holes 111. In the illustrated embodiment, each of the profile segments 101, 102, 103 has two through holes 110 and two elongated holes 111, which are arranged opposite each other along the transverse axis Q1. For illustrative purposes, only the through holes 110 and elongated holes 111 of the third profile segment 103 are provided with reference numerals (see figure). Fig. 2 ).

[0053] In the illustrated embodiment, the two pivot axes G1, G2 of the mounting profile 100 are each designed as a solid-body joint 112, 113. The two solid-body joints 112, 113 can also be referred to as the first solid-body joint 112 and the second solid-body joint 113. The first solid-body joint 112 connects the first profile segment 101 and the second profile segment 102 to each other in a pivotally angular manner. The second solid-body joint 113 connects the second profile segment 102 and the third profile segment 103 to each other in a pivotally angular manner.

[0054] In this case, the first profile segment 101 has opposing wing sections 1011 and 1012 along the transverse axis Q1 of the mounting profile 100. These sections can also be referred to as the first wing section 1011 and the second wing section 1012. A central section 1013 of the first profile segment 101 is arranged between the two wing sections 1011 and 1012. The two wing sections 1011 and 1012 are each pivotally connected to the central section 1013 about a wing hinge axis FG1 and FG2, respectively. The two wing hinge axes FG1 and FG2 are parallel to each other and extend longitudinally along the longitudinal axis L1 of the mounting profile. The wing hinge axes FG1 and FG2 are also designed as rigid hinges (without reference numerals).

[0055] The wing sections 1011 and 1012 each have a connecting section 1014 and 1015, respectively. The connecting sections 1014 and 1015 are arranged at the leading end of the first airfoil segment 101 facing the second airfoil segment 102 and are designed to form a positive-locking connection with complementary connecting sections 1021 and 1022 of the second airfoil segment 102. This positive-locking connection is achieved by the interlocking of the connecting sections 1014 and 1015 and the complementary connecting sections 1021 and 1022, and requires the wing sections 1011 and 1012 to be angled relative to the central section 1013 and the first airfoil segment 101 to be angled relative to the second airfoil segment 102 (see figure). Fig. 15 In the embodiment shown, the connecting sections 1014, 1015 are projections and the complementary connecting sections 1021, 1022 are recesses. In principle, a reverse design is also conceivable.

[0056] In the embodiment shown, the third profile segment 103 also has wing sections, the design of which is subject to the aforementioned descriptions. The wing sections of the third profile segment 103 and their positive-locking connection with the second profile segment 102 are not explained separately.

[0057] In the illustrated embodiment, the mounting profile is made of a plastic material K. Specifically, it is manufactured by injection molding. The solid hinges 112, 113, when made of plastic, can preferably be designed as film hinges. The same applies to the wing hinge axes FG1, FG2.

[0058] In the embodiment shown, the support profile 200 is also made of plastic; in this case, it is also manufactured from the plastic material K.

[0059] To start from the in Fig. 1 To enable easy and practical angling of the two profile legs 201, 202 in the flat configuration of the support profile 200 shown, a film hinge (without reference numeral) is provided. The film hinge connects the two profile legs 201, 202 to each other in an angularly articulated manner.

[0060] In the embodiment shown, both the fixing profile 300 and the hook part 400 are made of aluminum A.

[0061] Furthermore, in the illustrated embodiment, the fixing profile 300 has an adhesive strip 303. This strip is arranged on the upper surface 301 of the fixing profile 300 and extends longitudinally over the entire length of the fixing profile 300. The adhesive strip 303 is arranged transversely between the two edge edges 304, 305. In the Fig. 1 In the configuration shown, the adhesive strip 303 is protected by a removable protective film (not shown in detail). The adhesive strip 303 is designed to form an adhesive bond with the underside 502 of the window sill 500.

[0062] The following describes the different support brackets 1, 1a, 1b, 1c, 1d and their different installation situations with reference to the Fig. 3 bis 22 explained.

[0063] The support bracket 1 according to the Fig. 3 bis 5 It is formed using the mounting profile 100, the fixing profile 300 and optionally the hook part 400 of kit 2000. The support profile 200 of kit 2000 is not part of the support holder 1 according to the Fig. 1 bis 5 In the support bracket 1, the mounting profile 1 remains in a non-angled state with the profile segments 101, 102, 103. In other words, the mounting profile 100 remains flat. To form the support bracket 1, the fixing profile 300 is connected to the plug-in receptacle 106 of the mounting profile 100 in a longitudinally slidable manner. The plug-in connection is formed along the entire length of the mounting profile 100 and thus with each of the individual plug-in receptacle sections 1061, 1062, 1063. In this connected state with the fixing profile 300, the profile segments 101, 102, 103 are in the position specified in the Fig. 3 bis 5 The shown, non-angled state is established. Furthermore, the first hook leg 401 is inserted into the plug-in receptacle 306 of the fixing profile 300. In the Fig. 4 and 5 In the installation situation shown, the first hook leg 401 is completely inserted into the plug receptacle 306.

[0064] The facade (without reference symbol) consists of masonry M and an external thermal insulation composite system W applied to the masonry M. The latter will subsequently be referred to simply as thermal insulation W.

[0065] To fix the window sill 500, the back 104 of the fastening profile 100 is placed on a horizontal reveal surface FH of the wall opening and screwed to it. The screw connection is not shown in the figures. The horizontal reveal surface FH is parallel to the horizontal in the transverse direction of the wall opening and slopes down towards the weather side in the depth direction of the wall opening to allow for proper drainage, i.e., the flow of precipitation from the top 501 of the window sill 500 to the outside. The underside 502 of the window sill, opposite the top 501, rests on the top 301 of the fixing profile 300 and is bonded with the adhesive strip 303. For additional fixation, the second hook leg 402 is hooked into the support groove 502. The support groove 502 is located on a lower edge of a wall apron 504 of the window sill 500.The support groove 505 receives a lower end face 4021 of the second retaining leg 402 in a form-fitting manner.

[0066] In the Fig. 4 and 5 In the installation situation shown, the fixing profile 300 protrudes towards the outside / weather side beyond the mounting profile 100.

[0067] In Fig. 6 is a support bracket 1' as a variant of the support bracket 1 according to Fig. 3 An alternative installation situation is shown. The support bracket 1' is identical in construction to the support bracket 1, except that the hook part is omitted. For additional sealing, a joint tape 600 is installed between the underside 502 of the window sill 500 and the horizontal reveal surface FH. The fixing profile 300 is recessed inwards relative to the joint tape 600 and lies completely within an area sealed by the joint tape 600.

[0068] The support bracket 1a according to the Fig. 7 bis 9 It is designed using the mounting profile 100, the support profile 200, the fixing profile 300 and optionally the hook part 400 of kit 2000. Similar to the support bracket 1 according to Fig. 3 The mounting profile 100 is intended to be used in a flat, non-angled position.

[0069] To form the support bracket 1a, the first profile leg 201 is inserted into the first insertion section 1061 of the first profile segment 101. The fixing profile 300 is then inserted into the insertion section 206 of the second profile leg 202 of the support profile 200 in a longitudinally displaceable manner. The hook part 400 is inserted with its first hook leg 401 into the insertion section 306 of the fixing profile 300 in a longitudinally displaceable manner. In the formed state of the support bracket 1a, the second profile leg 202 projects beyond the front face 105 of the fastening profile 100. The second profile leg 202 projects approximately at a right angle to the front face 105, in this case at an angle of approximately 85°. The fixing profile 300 projects inwards beyond the rear face 104 of the fastening profile 100. In addition, the fixing profile 300 protrudes slightly beyond the second profile leg 202 to the outside.The first hook leg 401 is not fully inserted into the plug-in receptacle 306 of the fixing profile 300.

[0070] In the Fig. 8 and 9 In the installation situation shown, the back side 104 of the fastening profile 100 is placed against a vertical facade surface FV and screwed to it, although the screw connection is not shown in the figures.

[0071] The vertical facade surface FV is located in the Fig. 8 and 9 In the installation situation shown, the exterior of the masonry M is the mounting profile. The fixing profile 100 is therefore positioned between the masonry M and the thermal insulation W. The second profile leg 202, together with the fixing profile and the hook part 400, lies above an upper edge of the thermal insulation W and the masonry M. The second profile leg 202 projects outwards beyond the vertical facade surface FV, while the fixing profile 300 projects both outwards and inwards.

[0072] In Fig. 10 is a support bracket 1a' as a variant of the support bracket 1a according to Fig. 3 An alternative installation situation is shown. This installation situation again uses a joint tape 600. The support bracket 1a is identical in construction to the support bracket 1a, except for the missing hook part 400.

[0073] The support bracket 1b according to the Fig. 11 bis 13 The kit 2000 is formed using the mounting profile 100, the support profile 200, the fixing profile 300 and optionally the hook part 400. Angled use of the mounting profile 100 is provided for.

[0074] To form the support holder 1b, the first profile segment 101 is first angled relative to the second profile segment 102. As shown in the Fig. 11 bis 13 As shown, profile segment 101 is angled from its flat orientation towards the rear side 104 of the mounting profile 100. The first profile segment 101 and the second profile segment 102 form an angle of approximately 95°. The third profile segment 103 remains flat and not angled relative to the second profile segment 102. Furthermore, the first profile leg 201 of the support profile 200 is connected to the second plug-in section 1062 of the second profile segment 102. The longitudinal axis L22 of the second profile leg 202 is thus aligned coaxially with a longitudinal axis (without reference numeral) of the first profile segment 101. The same applies to the first plug-in section 1061 and the plug-in receptacle 206.After joining the fastening profile 100 and the support profile 200, the fixing profile 300 can be inserted into the socket 206 of the second profile leg 202 and the first socket section 1061 of the first profile segment 101. Finally, the first hook leg 401 is joined to the socket 306 of the fixing profile.

[0075] In the Fig. 12 and 13In the installation situation shown, the back sides of the second profile segment 102 and the third profile segment 103 are placed against the vertical facade surface FV and screwed to it, although the screw connection is not shown in the figures. The first profile segment 101 projects inwards beyond the vertical facade surface FV and is positioned vertically above the masonry M. The second profile leg 202 projects outwards beyond the vertical facade surface FV and is positioned vertically above the thermal insulation W. The vertical facade surface FV is formed by an outer surface of the masonry M and is therefore located between the masonry M and the thermal insulation W.

[0076] In Fig. 14 is a support bracket 1b' as a variant of the support bracket 1b according to Fig. 11 shown. The support bracket 1b' does not have a hook part 400 and, apart from this, is identical in construction and installation to the support bracket 1b. For improved sealing, the in Fig. 14 The installation situation shown again uses a 600 mm joint tape.

Similar to the support bracket 1b according to the Fig. 11 bis 13 , again an angled use of the mounting profile 100 is provided.

[0078] To form the support bracket 1c, the first profile segment 101 is again first angled relative to the second profile segment 102. The same principles apply here as described for support bracket 1b. To avoid repetition, reference is made to the information provided for support bracket 1b. After the first profile segment 101 has been angled, its wing sections 1011 and 1012 are additionally angled relative to the central section 1013 in the direction of the rear face 104 of the mounting profile 100. It is understood that the wing sections 1011 and 1012 can also be angled first, followed by the first profile segment 101. The connecting sections 1014 and 1015 of the first profile segment 101 are engaged with the complementary connecting sections 1021 and 1022 of the second profile segment 102.The positive-locking connection formed in this way between the two profile segments 101, 102 further stabilizes the angled orientation of the mounting profile 100. The further assembly of the support bracket 1c is carried out analogously to the support bracket 1b. The same applies to the [unclear - possibly referring to the following]. Fig. 16 and 17 The installation situation shown is essentially the same as described in the Fig. 12 and 13 The installation situation shown corresponds to this.

The support bracket 1d is designed for angled use of the mounting profile 100.

[0081] To form the support bracket 1d, the third profile segment 103 is angled relative to the second profile segment 102. For this purpose, the third profile segment 103 is angled towards the rear side 104 of the mounting profile 100 at approximately a right angle to the two other profile segments 101 and 102. In this angled state, the third profile segment 103 and the second profile segment 102 form an angle of 95°. The first profile segment 101 remains flat relative to the second profile segment 102 and is therefore not angled. The first profile leg 201 of the support profile 200 is then connected to the plug-in section 1063 of the third profile segment 103. When assembled, the longitudinal axis L22 of the second profile leg 202 is coaxial with the longitudinal axis (without reference numeral) of the two profile legs 101, 102. The same applies to the plug-in receptacle 206 of the second profile leg 202 and the two plug-in receptacle sections 1061, 1062.Next, the fixing profile 300 is assembled with the plug-in receptacle 206 and the plug-in receptacle sections 1061, 1062.
