Description

[0001] The present application relates to a retaining profile according to claim 1, a window sill according to claim 20 and an arrangement comprising a retaining profile and a window sill according to claim 25. Technological background

[0002] Window sills are used to cover the tops of a building's window parapets. Exterior window sills are primarily used to divert rainwater from the window opening on the building's facade. For this purpose, a window sill is attached to a frame or a window sill connection profile using a retaining profile.

[0003] Currently, installing a window sill on a support profile requires multiple components, which also necessitates multiple work steps. This makes installing a window sill on a support profile particularly complex and time-consuming, even when several specialists are involved. Printed state of the art

[0004] DE 19 46 206 C3 relates to a fastening system for a window sill to a frame using a locking strip screwed to the frame, which forms an upper undercut with the frame and has a groove underneath. The window sill includes a fastening bar that engages in the upper undercut. A hook profile is also provided as a separate component, which must be slid onto the window sill along a strip. The hook profile engages in the lower groove via a flexible hook bar. Object of the present invention

[0005] The object of the present invention is to provide a retaining profile for a window sill that enables simplified installation of the window sill. Furthermore, the object of the present invention is to provide a window sill that ensures simple installation. Solution to the task

[0006] The above object is achieved by the retaining profile according to claim 1, by a window sill according to claim 20, and by an arrangement comprising a retaining profile and a window sill according to claim 25. Advantageous embodiments of the present invention are claimed in the dependent claims.

[0007] According to the invention, the main body of the holding profile comprises a pivot arm which is arranged in the region of a first end region of the base of the main body and can be pivoted towards a receiving device of the base, so that when the pivot arm is pivoted towards the receiving device, a receiving gap for a window sill remains between a free end of the pivot arm and the receiving device. The holding profile makes it possible, in particular, for a window sill to be suspended in the receiving device and then secured by pivoting the pivot arm towards the receiving device. This eliminates the need for screwing or any other means of fixing the window sill. Furthermore, no separate parts are required, which can easily be lost on site. This simplifies the installation of the window sill to the holding profile.

[0008] The base of the retaining profile is an integral part of a window sill connection profile or serves to attach the retaining profile to a mounting surface, e.g., a mounting surface on a window sill connection profile or a frame. The frame is preferably part of a window construction, in particular a window construction made of aluminum, wood, or plastic, or a composite of at least two of the aforementioned materials.

[0009] The base and swivel arm are conveniently constructed as a single piece. This ensures particularly easy installation of the window sill to the support profile.

[0010] Preferably, the pivot arm is pivotable by means of a hinge. The hinge is preferably a solid-state hinge, particularly preferably a film hinge. This allows a pivot axis to be defined, particularly one extending over the entire length of the support profile, allowing the pivot arm to be pivoted particularly easily.

[0011] The swivel arm expediently has a locking means, in particular a locking recess, at its free end. This allows the swivel arm to lock, preferably in a positive-locking manner, with a counterpart in the position pivoted toward the receiving device.

[0012] Since the locking means on the pivot arm can be brought into engagement with a locking means, in particular a locking projection, of the window sill in the position of the pivot arm pivoted towards the receiving device, the window sill can be easily fastened by locking the locking means of the pivot arm with the locking means of the window sill.

[0013] Advantageously, a web can be provided at the free end of the pivot arm, which extends at an angle, preferably at an angle of less than 90°, to the pivot arm. The locking means, in particular the locking recess, is preferably arranged on the web. In particular, the angle of the web is adapted to the inclination of the window sill, so that the web runs essentially parallel to a window sill inserted into the receiving gap.

[0014] As the web rests with its free end on the base in the position of the swivel arm pivoted towards the receiving device, forces acting on the swivel arm can be effectively transferred to the base.

[0015] Preferably, the pivot arm comprises a support element which, when the pivot arm is pivoted toward the receiving device, rests against the first end region of the base, in particular against a web arranged at the first end region of the base. This allows the forces acting on the pivot arm to be transferred to the base in a particularly favorable manner. This reduces the mechanical load on the web.

[0016] Preferably, the contact element is arranged next to a recess provided in the hinge. This allows the forces acting on the pivot arm to be effectively directed away from the hinge, thus reducing the hinge's exposure to mechanical stress.

[0017] The retaining profile expediently comprises a seal arranged at the free end of the pivot arm, which, when the pivot arm is pivoted toward the receiving device, rests against the upper side of the inserted window sill. The seal is preferably arranged on a side of the pivot arm facing away from the base. This prevents water from penetrating the interior of the retaining profile during rainfall, particularly heavy rain.

[0018] By including a seal on the base, the retaining profile prevents water from penetrating between the base and the mounting surface.

[0019] Preferably, the base body has a higher Shore hardness, in particular Shore A hardness, than the seal arranged on the pivot arm and / or a higher Shore hardness, in particular Shore A hardness, than the seal arranged on the base body.

[0020] The fact that the locking means and / or the web and / or the contact element and / or the seal arranged on the pivot arm and / or the seal arranged on the base can extend continuously over the entire length of the holding profile can simplify the manufacture of the holding profile.

[0021] Preferably, the retaining profile or the base body is an extruded profile. Preferably, the seals are extruded onto the base body. Particularly preferably, the retaining profile is a coextruded profile.

[0022] Advantageously, the receiving device comprises a web running substantially parallel to the base, with a recess provided between the web and the base. In particular, the web and the base are integrally connected to one another. A window sill suspension device, particularly a corresponding one, can be easily suspended, preferably in a form-fitting manner, in the receiving device. This allows the window sill to be held in a predefined position in the retaining profile.

[0023] Since the web has a flat contact surface on its outer side facing away from the base, the suspension device, e.g. a web of the suspension device, can lie flat against the contact surface.

[0024] Because the base body includes at least one through-hole or at least one screw-in notch, the retaining profile can be easily attached to the mounting surface using a screw. The screw can be positioned in the screw-in notch and screwed through the retaining profile.

[0025] Since the window sill connection profile can be fixed, in particular clipped, to the frame, both profiles can be mounted together, preferably in one assembly step.

[0026] Advantageously, the window sill connection profile can be arranged on a side of a frame facing a window sill or a facade element sill. This ensures that the window sill is positioned below a window.

[0027] Advantageously, the retaining profile is arranged on the outside of the building.

[0028] The retaining profile is conveniently made of plastic.

[0029] In addition, a window sill is claimed, which according to the invention comprises a suspension device on a side of the window sill facing the window parapet, in particular on the underside. By means of the suspension device, the window sill can preferably be suspended in a receiving device of a retaining profile according to one of claims 1-19.

[0030] Advantageously, the suspension device comprises a first web and a second web, wherein the first web and the second web are positioned at a distance from one another. In particular, the webs are arranged parallel to one another. Preferably, the webs are an integral part of the window sill.

[0031] Advantageously, a recess is provided between the spaced-apart webs, which can be brought into engagement with a counterpart of a receiving device of a retaining profile. This allows the window sill to be held, particularly in a form-fitting manner, in the retaining profile.

[0032] By providing the window sill with a locking means, in particular a locking projection, arranged on a side facing away from the window sill, in particular the top side, which can be brought into engagement with a locking means, in particular a locking recess, of a retaining profile, the window sill can be fixed in position by means of a locking mechanism, e.g., with a pivoting arm. The locking means is thus arranged on the side of the window sill opposite the suspension device.

[0033] Advantageously, the suspension area and / or the locking means extend continuously over the entire length of the window sill. This allows the window sill to be manufactured preferably using an extrusion or continuous casting process.

[0034] The window sill is preferably made of plastic or aluminum.

[0035] Advantageously, the window sill is an external window sill, whereby the external window sill preferably has a drip nose.

[0036] In addition, an arrangement is claimed which comprises a holding profile according to one of claims 1-19 and a window sill according to one of claims 20-24. Description of the invention based on exemplary embodiments

[0037] Advantageous embodiments of the present invention are explained in more detail below with reference to the drawing figures. They show: Fig. 1 a sectional view of an example of a window construction installed in a building facade with an arrangement according to the invention comprising a holding profile and a window sill; Fig. 2a a sectional view of the retaining profile according to Fig. 1 with a swivel arm in a non-swivelled position; Fig. 2b a sectional view of the retaining profile according to Fig. 1, wherein the pivot arm is pivoted towards a receiving device of the holding profile; Fig. 3 a sectional view of a side of the window sill facing the building façade according to Fig. 1; Fig. 4 a sectional view of the arrangement according to Fig. 1, where the window sill is not hooked into the retaining profile; Fig. 5 a sectional view of the arrangement according to Fig. 1, whereby the window sill is suspended in the retaining profile; Fig. 6 a sectional view of the arrangement according to Fig. 1, whereby the window sill is locked to the swivel arm of the retaining profile; Fig. 7 a sectional view of an example of a window sill connection profile with a retaining profile as an integral part of the window sill connection profile.

[0038] Fig. Figure 1 shows a sectional view through a window construction installed on a window sill 5 of a building facade 3. The window construction comprises a frame 2 and a window sash 9 with several window panes 10. A window sill connection profile 4 is provided below the frame 2. The window sill connection profile 4 is clipped and secured to the frame 2 via snap-in devices 8. The window sill connection profile 4 comprises several cavities 7 that serve for insulation.

[0039] An assembly 1 is mounted on the window sill connection profile 4. The assembly 1 comprises a retaining profile 100 and a window sill 20. The retaining profile 100 is attached to the window sill connection profile 4 and serves to fix the window sill 20.

[0040] Alternatively, the retaining profile 100 can also be connected directly to the frame 2, so that no window sill connection profile 4 is required.

[0041] As in Fig. 1, the window sill 20 is an external window sill with a cladding area 21 and a drip nose 24 for draining rainwater from the building facade 3.

[0042] The holding profile 100, see Fig. 2a and Fig. 2b, comprises a main body 101 with a base 102 and a pivot arm 105. The main body 101 comprises a screw-in notch 111 arranged on the base 102. The screw-in notch 111 serves as an attachment point for a screw 6, cf. Fig. 4-6, to attach the holding profile 100 to a fastening surface of the frame 2 or the window sill connection profile 4.

[0043] The base 102 comprises a first end region 103 and a second end region 104. At the second end region 104, a receiving device 115 is provided, which can be brought into engagement with a hanging device 22 of the window sill 20, see. Fig. 4-6. The receiving device 115 comprises a web 117 which runs essentially parallel to the base 102 and is integrally connected to the base 102, cf. Fig. 2a and Fig. 2b. Furthermore, a recess 116 is provided, which is arranged between the base 102 and the web 117. The web 117 comprises a flat contact surface 120 on its outer side facing away from the base 102.

[0044] The pivot arm 105 is arranged at the first end region 103 of the base 102 and is connected via a hinge 107 to a web 113 at the first end region 103 of the base 102. In the area of ​​the hinge 107, the base 102 and the pivot arm 105 taper, so that the base body 101 has a recess 114 in the area of ​​the hinge 107.

[0045] The swivel arm 105 is pivoted by means of the hinge 107 from a non-pivoted position, cf. Fig. 2a, pivotable in the direction of the receiving device 115, cf. Fig. 2b. In the position of the pivot arm 105 in which it is pivoted towards the receiving device 115, a receiving gap 121 remains between the free end 106 of the pivot arm 105 and the receiving device 115, into which the window sill 20 can be inserted.

[0046] As in Fig. 2a and Fig. As shown in Figure 2b, the pivot arm 105 and the base 102 are formed integrally. As a result, the hinge 107 is also formed integrally with the pivot arm 105 and the base 102. Accordingly, the hinge 107 is a solid-state hinge, in particular a film hinge.

[0047] The pivot arm 105 comprises a web 109 at its free end 106, which extends at an angle of less than 90° to the pivot arm 105. The angle is adapted to the inclination of the window sill 20. A locking recess 108 is provided on the web 109, which can engage with a corresponding locking projection 23 of the window sill 20 in a form-fitting manner, see. Fig. 6.

[0048] When the pivot arm 105 is pivoted toward the receiving device 115, the web 109 rests with its free end 110 against the base 102. Furthermore, a contact element 112 is provided on the pivot arm 105 in the region of the recess 114, which contact element 112 rests against the web 113 when the pivot arm 105 is pivoted toward the receiving device 115. This allows forces acting on the pivot arm 105 to be transmitted to the base 102 via the free end 110 and the contact element 112. As a result, the forces are not dissipated via the hinge 107, thereby reducing the mechanical load on the hinge 107.

[0049] Furthermore, a seal 118 is provided at the free end 106 of the pivot arm 105 to prevent water from penetrating the interior of the support profile 100. Additionally, a seal 119 is provided at the base 102 to prevent water from penetrating between the base 102 and a mounting surface. The hardness of the seal 118 and / or the seal 119 is lower than the hardness of the base body 101.

[0050] The retaining profile 100 is an extruded, preferably coextruded, profile. Accordingly, the locking recess 108 and / or the web 109 and / or the contact element 112 and / or the seal 118 and / or the seal 119 extend continuously over the entire length of the retaining profile 100.

[0051] Fig. 3 shows a sectional view of the window sill 20. The window sill 20 comprises the cladding area 21, which extends along the window parapet 5, cf. Fig. 1. The window sill 20 further comprises a suspension device 22, which is arranged on the underside of the window sill 20, i.e., on the side of the window sill 20 oriented toward the window parapet 5. The suspension device 22 comprises two mutually parallel webs 22a, 22c, wherein the webs 22a, 22c are an integral part of the window sill 20. A recess 22b is provided between the webs 22a, 22c. By means of the suspension device 22, the window sill 20 can be suspended in the corresponding receiving device 115 of the holding profile 100. In addition, the window sill 20 comprises a locking projection 23 arranged on its upper side, which locks into the corresponding locking recess 108 of the holding profile 100.

[0052] The suspension area 22 and / or the locking projection 23 preferably extend over the entire length of the window sill 20, so that it can be manufactured by means of an extrusion process or by means of a continuous casting process.

[0053] Fig. 4-6 show a sequence of assembly steps for mounting the window sill 20 to the retaining profile 100. Here, the retaining profile 100 is fastened with a screw 6 to a mounting surface, e.g., a window frame 2 or a window sill connection profile 6.

[0054] According to Fig. 4 and Fig. 5, the window sill 20 is first suspended from the retaining profile 100. The suspension device 22 of the window sill 20 and the receiving device 115 of the retaining profile 100 engage with each other. The second web 22c of the window sill 20 is inserted into the recess 116 of the retaining profile 100. The web 117 of the retaining profile 100 engages the recess 22b of the window sill 20. The first web 22a of the window sill 20 rests flat against the contact surface 120 of the web 117. As a result, a positive connection is created between the suspension device 22 and the receiving device 115, whereby the window sill 20 is held by the retaining profile 100.

[0055] After the window sill 20 is suspended in the retaining profile 100, the pivot arm 105 is pivoted toward the receiving device 115. The pivot arm 105 is pivoted by means of the hinge 107, so that the locking projection 23 on the upper side of the window sill 20 engages the recess 108 of the pivot arm 105 in a form-fitting manner, see. Fig. 6. The locking mechanism ensures a secure connection between the window sill 20 and the retaining profile 100. As a result, screwing the window sill 20 is no longer necessary.

[0056] As in Fig. As shown in Figure 6, the angle of the web 110 to the pivot arm 105 is adapted to the inclination of the window sill 20. As a result, the web 110 and the window sill 20 run parallel to each other, which facilitates the locking of the locking recess 108 and the locking projection 23.

[0057] When the pivot arm 105 is pivoted toward the receiving device 115, the seal 118 arranged on the pivot arm 105 rests against the upper side of the window sill 20. This prevents water from penetrating the retaining profile 100, particularly during heavy rain events.

[0058] According to an alternative embodiment, the base 102 of the holding profile 100 can also be an integral part of the window sill connection profile 4, cf. Fig. 7. All other components of the retaining profile 100 are essentially identical. Only the seal 119 is no longer required in this design.

[0059] Because the base 102 and thus the retaining profile 100 are an integral part of the window sill connection profile 4, the retaining profile 100 no longer needs to be mounted to the window sill connection profile 4. This eliminates this additional work step. Thus, the window sill 20 only needs to be suspended in the retaining profile 100 and secured by pivoting the pivot arm 105.
