Description

[0001] The present invention relates to a frame, in particular a window or door frame, with a corner sealing element. The invention further relates to a corner sealing element for frames, in particular for window or door frames.

[0002] Window and door frames, especially frame and sash frames, have a frame profile, which is generally composed of four profile sections, at least in the case of rectangular windows and doors. These extruded profile sections are usually connected at right angles. Seals meet at the abutting edges of two adjacent profile sections. A continuous insulating effect is not always achieved directly by the seals between the profile sections. Rather, these are subsequently sealed with sealants.

[0003] Sealing frame corners and T-joints on window and door frames with the sealants mentioned above cannot always be achieved with the desired quality. In other words, it is not a sealing process that can be easily repeated. To increase process reliability, corner sealing elements are known from the state of the art. These are inserted between the two profile parts, for example, at the corners or T-joints, and feature a guide channel for the sealant.

[0004] Such a corner sealing element is known, for example, from EP 2 754 838 B1. The corner sealing element known from EP 2 754 838 B1 has a plurality of distribution channels designed to distribute sealing compound along the frame profile. These known solutions allow the sealants to be injected into the corner sealing element and then distributed to the desired locations via the distribution channels to achieve reliable sealing. According to the statements in EP 2 754 838 B1, this allows both the volume of the required sealants and the position of the sealants to be adjusted relatively precisely. Furthermore, a semi-automated or fully automated injection process for the sealant through the corner sealing element is possible.

[0005] When designing distribution channels according to the state of the art, reliable processing is strongly influenced by the viscosity of the sealant. Sealants with particularly high viscosity are rarely suitable for distribution through the distribution channels to the desired locations on the frame profile. Rather, this can lead to clogging of the distribution channels, meaning that in some cases, not every desired part of the frame profile can be sealed with sealant. Furthermore, the viscosity depends on the processing temperature and therefore cannot be guaranteed consistently.

[0006] The document DE 20 2016 101 390 U1 relates to a central sealing block for a lift-and-slide door for placement between a fixed leaf and a structural profile raising a floor threshold. The central sealing block comprises a base extending in the longitudinal direction of the structural profile and a crossbar adjoining the base at a right angle. It is provided that at least one downwardly open sealing / adhesive chamber is formed on an underside facing the structural profile, which has at least one filling opening opening toward the top.

[0007] The present invention is based on the object of providing a frame and a corner sealing element with which a reliable sealing of corner areas can be ensured, regardless of the viscosity of the sealing material.

[0008] According to the invention, this object is achieved by a frame according to independent claim 1.

[0009] Accordingly, the present invention relates to a frame, in particular a window or door frame, comprising a frame profile with a corner where two adjacent profile parts meet. The frame further comprises a corner sealing element mounted in the at least one corner of the frame profile such that a first surface of the corner sealing element abuts a first profile part of the frame profile and a second surface of the corner sealing element abuts a second profile part of the frame profile.The corner sealing element forms, together with the frame profile, separate first and second sealing spaces for receiving sealants, wherein the first and second sealing spaces are each partially delimited by the first and second profile parts of the frame profile, and wherein the sealing element has a first opening for filling the first sealing space with sealant and a second opening for filling the second sealing space with sealant.

[0010] By dividing the corner sealing element into at least two sealing chambers, the use of narrow channels is advantageously eliminated. Instead, the sealants can be injected directly into the sealing chambers and thus directly onto the side walls of the profile parts using the solution described here. With the present invention, sealing with the sealants is not dependent on the viscosity of the sealants and is therefore repeatable even at a wide range of temperatures.

[0011] According to a further embodiment, the two profile parts each have an outer shell, which is connected to an inner shell via at least one insulating bar. The at least one insulating bar has a first end connected to the inner shell and a second end connected to the outer shell, wherein the first sealing space covers the first end of the insulating bar and / or wherein the second sealing space covers the second end of the insulating bar. Accordingly, the two sealing spaces of the corner sealing element can be used to repeatedly seal the ends of the insulating bars, thus efficiently preventing thermal bridges.

[0012] According to the invention, the corner sealing element has a separating element which, together with the frame profile, separates the two sealing spaces from each other in such a way that a transfer of sealants between the sealing spaces is prevented.

[0013] By providing partition walls between the sealing chambers, it is ensured that sealants only spread within the designated sealing chambers. This limits the amount of sealant that can be introduced into each sealing chamber, preventing curing before the sealing chambers are completely filled. However, it is also conceivable that, in some embodiments, the partition walls are designed to be detachable. Accordingly, the partition walls can be removed at any time to connect adjacent sealing chambers, for example, if the opening of one of the sealing chambers is difficult to access.

[0014] According to a further embodiment of the present invention, the first and second openings are arranged on a surface of the corner sealing element spaced apart from the frame profile. According to this refinement, the openings are always freely accessible for filling the sealing spaces with sealants.

[0015] The first and second openings can be arranged on a surface facing away from the frame profile. In particular, this facing away surface can be designed such that the openings extend toward the abutting edge of the two adjacent profile parts. In other words, the openings of this embodiment can extend through the facing away surface toward the corner joint between the profile parts. Thus, the sealant can be introduced into the sealing spaces directly toward the abutting edge.

[0016] According to a further embodiment, the corner sealing element has a plurality of first anchoring elements which are designed to fasten the corner sealing element to undercuts of the first profile part, wherein the corner sealing element has a plurality of second anchoring elements which are designed to fasten the corner sealing element to undercuts of the second profile part.

[0017] According to this refinement, the corner sealing element can be connected to the two profile parts in a form-fitting manner. The anchoring elements can be designed such that the two profile parts can be inserted into the anchoring elements during frame assembly. As will be explained in more detail later, once the frame is assembled, it is no longer possible for the corner sealing element to become detached from the profile parts of the frame profile.

[0018] According to the invention, the corner sealing element has a concave surface facing away from the profile parts. The surface of the corner sealing element facing away from the profile parts forms, in particular, a new corner surface of the frame. The concave design of this surface results in a rounded corner, which allows the corner sealing element to be used not only for injecting sealants but also for avoiding sharp corners.

[0019] According to the invention, the first and second openings extend through the aforementioned concave surface. According to this embodiment, the concave surface also acts, in particular, as a guide element, facilitating the insertion of the spray guns into the openings.

[0020] According to a further embodiment, the two profile parts each have an outer shell, which is connected to an inner shell via at least one insulating web, wherein the first sealing chamber has a side opening that rests against a stop profile of the outer shell. According to this embodiment, the first sealing chamber can be used not only to seal the two profile parts of the frame profile against each other, but also to prevent air gaps between the corner sealing element and the outer shell.

[0021] According to a further embodiment of the present invention, the corner sealing element is made of a synthetic rubber, in particular EPDM. Of course, it is also possible in principle to manufacture the corner sealing element from other, less thermally conductive plastics. Manufacturing the corner sealing element from a synthetic rubber has the advantage that it can also be subsequently incorporated into the frame profile. In this case, for example, the aforementioned anchoring elements can be slipped over the undercuts of the profile parts thanks to the flexibility of the synthetic rubber.

[0022] The present invention further relates to a window or a door having one of the frames described above.

[0023] The present invention further relates to a corner sealing element for frames, in particular for window or door frames, wherein the at least one corner sealing element is designed to be mounted in a corner of a frame. The corner sealing element forms separate first and second sealing spaces for receiving sealants when the corner sealing element is inserted into a corner of a frame, wherein the sealing element has a first opening for filling the first sealing space with sealant and a second opening for filling the second sealing space with sealant. Advantageous embodiments of the frame according to the invention are described in more detail below with reference to the accompanying drawings. In the drawings: Fig. 1 is a perspective view of a corner part of a frame according to an embodiment of the present invention; Fig. 2 is a perspective view of a T-joint of a frame according to an embodiment of the present invention; Fig. 3 an enlarged view of the Fig. 2 frame shown, from the right; and Fig. 4 a perspective rear view of a corner sealing element according to an embodiment of the present invention.

[0024] Fig. Figure 1 shows a perspective side view of a corner part of a frame 10 according to an embodiment of the present invention. The frame 10, in particular a window frame, has a frame profile with a first profile part 12, which is connected to a second profile part 14. In particular, the first and second profile parts 12, 14 are connected to one another via a miter joint, resulting in a miter joint 15 as the abutting edge between the two profile parts 12, 14.

[0025] The first profile part 12 has an inner shell 18, which is connected to an outer shell 20 via insulating webs 22, 24. In the illustration according to Fig. 1, the inner shell 18 is connected to the outer shell 20, in particular via an inner insulating bar 22 and an outer insulating bar 24. When using the frame 10, the inner insulating bar 22 is the insulating bar closest to the sash frame.

[0026] The second profile part 14 has an inner shell 26, which is connected to an outer shell 28 via insulating webs 30, 32. In the illustration according to Fig. 1, the inner shell 26 is connected to the outer shell 28, in particular via an inner insulating bar 30 and an outer insulating bar 32. When using the frame 10, the inner insulating bar 30 is the insulating bar closest to the sash frame.

[0027] As in Fig. As further shown in Figure 1, the frame 10 has a corner sealing element 16 arranged in the corner of the frame profile. In particular, the corner sealing element 16 is arranged in the corner of the frame profile such that it at least partially covers the miter joint. The corner sealing element is designed such that it rests with a first surface against the first profile part 12 of the frame profile and with a second surface against the second profile part 14 of the frame profile.

[0028] The corner sealing element 16, together with the frame profile, forms separate first, second, and third sealing spaces for accommodating sealants. The sealing spaces can be filled with sealant via a corresponding number of openings (here three), as will be described later, particularly with reference to Fig. 3 will be explained in more detail.

[0029] The Fig. Figure 2 shows a perspective view from the left of a frame according to another embodiment of the present invention. The frame 110, in particular a frame, which in Fig. 2, has a T-connection consisting of two profile parts 112, 114. In other words, a first profile part 112 of the frame 110 forms a T-shaped butt joint with a second profile part 114. The butt edge 115 between the first and second profile parts 112, 114 forms two corners that are to be sealed.

[0030] The first profile part 112 has an inner shell 118, which is connected to an outer shell 120 via insulating webs 122, 124. In the illustration according to Fig. 2, the inner shell 118 is connected to the outer shell 120, in particular via an inner insulating bar 122 and an outer insulating bar 124. When using the frame 110, the inner insulating bar 122 is the insulating bar closest to the sash frame.

[0031] The second profile part 114 has an inner shell 126, which is connected to an outer shell 128 via insulating webs 130, 132. In the illustration according to Fig. 2, the inner shell 126 is connected to the outer shell 128, in particular via an inner insulating bar 130 and an outer insulating bar 132. When using the frame 110, the inner insulating bar 130 is the insulating bar closest to the sash frame.

[0032] In the Fig. 2, a corner sealing element 116 is shown, which seals a first corner of the T-connection. For this purpose, the corner sealing element 116 is arranged with a first surface on the first profile part 112 and with a second surface on the second profile part 114. As shown in the Fig. 2, the corner sealing element 116 according to the embodiment in Fig. 2 has a plurality of openings which are connected to separate sealing spaces. In particular, the corner sealing element 116 of the Fig. 2 has four openings which are connected to four different sealing chambers, as described in relation to Fig. 4 will be explained in more detail.

[0033] The corner sealing element 116 of the Fig. 2 differs from the corner sealing element of the Fig. 1 accordingly, in particular in that the corner sealing element 116 is longer and has four openings instead of the Fig. 1 has the three openings shown.

[0034] The Fig. 3 is an enlarged view (from the right) of the Fig. 2 illustrated embodiment. The Fig. 3 shows in particular the abutting edge between the outer shells 120, 128, the insulating webs 122, 130 and the inner shells 118, 126 of the first and second profile parts 112, 114. This abutting edge is formed according to the embodiment in the Fig. 2 and Fig. 3 partially covered by a corner sealing element 116.

[0035] The first profile part 112 has a plurality of foot profiles 140, 142, 144 arranged on the inner side of the first profile part 112. In particular, the inner insulating web 122 of the first profile part 112 has first and second foot profiles 140, 142 extending along the longitudinal direction of the first profile part 112. The outer shell 120 of the first profile part 112 has a foot profile 144 extending along the longitudinal direction of the first profile part 112.

[0036] The second profile part 114 has a plurality of foot profiles 134, 136, 138 arranged on the inner side of the second profile part 114. In particular, the inner insulating web 130 of the second profile part 114 has first and second foot profiles 134, 136 extending along the longitudinal direction of the second profile part 114. The outer shell 128 of the second profile part 114 has a foot profile 144 extending along the longitudinal direction of the second profile part 114.

[0037] The corner sealing element 116 has a plurality of first anchoring elements which are designed to attach the corner sealing element 116 to undercuts of the base profiles 140, 142, 144 of the first profile part 112. The first anchoring elements are designed with regard to the Fig. 4 is further explained.

[0038] The corner sealing element 116 has a plurality of second anchoring elements which are designed to attach the corner sealing element 116 to undercuts of the base profiles 134, 136, 138 of the second profile part 114.

[0039] The corner sealing element 116 can, in particular, be made of a flexible material. In some embodiments, this is a synthetic rubber, in particular EPDM. Accordingly, the corner sealing element 116 can be slipped over the base profiles 140, 142, 144 of the first profile part 112 and over the base profiles 134, 136, 138 of the second profile part 114. Due to the engagement of the anchoring elements in undercuts of the base profiles 134, 136, 138, 140, 142, 144, the corner sealing element 116 is positively connected to the frame profile. In particular, the corner sealing element 116 accordingly has a first surface that rests against the first profile part 112 and is connected to it. Furthermore, the corner sealing element 116 is connected to the second profile part 114 via a second surface and rests against its inner surface.

[0040] The Fig. Figure 3 further shows that the corner sealing element 116 has a concave surface 150. The concave surface 150 faces away from the abutting edge of the two profile parts 112, 114. In other words, the concave surface 150 is oriented toward the sash frame (not shown). Accordingly, the concave surface 150 of the corner sealing element 116 forms a rounded corner of the frame 110.

[0041] Although this is not the case in the Fig. 1 to 3, however, it should be noted that sealing strips are fundamentally arranged on the base profiles 134, 136, 138, 140, 142, 144 of the first and second profile parts 112, 114, which extend along the longitudinal direction of the two profile parts and abut against side surfaces 141, 143 of the corner sealing element 116. In other words, the corner sealing element 116 forms a connection between the (not shown) sealing strips. In this case, abutting edges between the two sealing strips and the corner sealing element 116 are sealed by sealants which are introduced into the sealing spaces ( Fig. 4) are inserted and connected to each other airtight.

[0042] The corner sealing element has a number of openings, each of which is connected to a separate sealing chamber. Fig. The corner sealing element 116 shown in Figure 3 has a first opening 152 connected to a first sealing chamber. The corner sealing element 116 has a second opening 154 connected to a second sealing chamber. The corner sealing element 116 has a third opening 156 connected to a third sealing chamber. The corner sealing element 116 has a fourth opening 158 connected to a fourth sealing chamber. The first to fourth sealing chambers are separated from one another so that sealants introduced into the sealing chambers via the openings 152, 154, 156, 158 cannot flow between the sealing chambers.

[0043] The first to fourth openings 152, 154, 156, 158 extend perpendicularly through the concave surface 150. Due to the alignment of the concave surface 150 relative to the frame profile, the openings 152, 154, 156, 158 extend in the direction of the abutting edge between the two profile parts 112, 114. Thus, sealants introduced into the sealing spaces via the openings 152, 154, 156, 158 can be sprayed directly onto the abutting edge between the two profile parts.

[0044] A perspective rear view of the corner sealing element 116 according to the embodiments of the Fig. 2 and Fig. 3 is the Fig. 4. As already mentioned above, the corner sealing element 116 has four openings 152, 154, 156, 158. The first opening 152 is connected to a first sealing chamber 151. The second opening 154 is connected to a second sealing chamber 153. The third opening 156 is connected to a third sealing chamber 155. The fourth opening 158 is connected to a fourth sealing chamber 157.

[0045] The first sealing chamber 151 is separated from the second sealing chamber 153 by a first partition wall 160. The second sealing chamber 153 is separated from the third sealing chamber 155 by a second partition wall 162. The third sealing chamber 155 is separated from the fourth sealing chamber 157 by a third partition wall 164.

[0046] It should be noted that the sealing spaces 151, 153, 155, 157 are partially delimited by the corner sealing element 116 and partially by the frame profile of the frame 110. In other words, the Fig. 4, the sealing spaces 151, 153, 155, 157 are delimited at the rear by the first and second profile parts, so that closed sealing spaces are formed between the corner sealing element 116 and the frame profile. The partition walls 160, 162, 164 also cooperate with the frame profile to separate the individual sealing spaces 151, 153, 155, 157 from each other. In the embodiment according to the Fig. 2 to 4, the partition walls 160, 162, 164 are accordingly designed such that they abut, with a first surface, against the base profiles 140, 142, 144 of the first profile part 112 and, with a second surface, against the base profiles 134, 136, 138 of the second profile part 114. Thus, the partition walls 160, 162, 164, together with the base profiles of the profile parts 112, 114, form a separation between the sealing spaces.

[0047] As already mentioned above, the corner sealing element 116 has a plurality of first anchoring elements 166, 168, 170, which are designed to be fastened to undercuts of the first profile part 112. The corner sealing element further has a plurality of second anchoring elements 172, 174, 176, which are designed to be fastened to undercuts of the second profile part 114. For this purpose, the first and second anchoring elements 166, 168, 170, 172, 174, 176 according to the Fig. 2 to 4, in particular, have T-shaped cutouts that can be slipped over the base profiles of the profile parts 112, 114. If the corner sealing element 116 is not made of a flexible material, the anchoring elements can also be used to insert the first and second profile parts into the T-shaped cutouts of the anchoring elements during frame manufacture.

[0048] The corner sealing element 116 is positively connected to the profile parts 112, 114 of the frame by the anchoring elements and accordingly cannot be separated from the profile parts even if the sealants expand within the sealing spaces.

[0049] The invention is not limited to the exemplary embodiments shown in the FIGS., but results from a combined consideration of all features disclosed herein. In particular, the invention is not limited to the Fig. 1 to 4. Rather, in further embodiments, the sealing element may have two or any higher number of sealing spaces and associated openings.
