Description

[0001] The invention relates to a threshold for supporting a frame and a fixed sash of a door or window on a building structure, comprising an elongated threshold body which is provided for direct or indirect attachment to the building structure and has a surface from which a stop step projects, extending along a longitudinal axis of the threshold body, and comprising at least one connecting element to be inserted between the surface of the threshold body and an underside of the frame or the fixed sash, wherein the connecting element has an underside designed for placement on the surface of the threshold body, an upper side facing the frame or the fixed sash and a lateral bearing surface designed for bearing against the stop step of the threshold body.

[0002] The threshold of a door or window is typically embedded in the floor slab of a building in such a way that the surface of the threshold or an intermediate profile attached to it is as flush as possible with the surface of the floor slab. The fixed sash can rest directly on the threshold or on the aforementioned intermediate profile, which transfers the weight of the fixed sash to the threshold. A track can also be arranged on the threshold, along which a movable sash can be slid in front of the fixed sash to create an opening.

[0003] Connecting elements such as frame corner connectors or center sealing blocks are used in floor thresholds of the aforementioned type to create a connection between the components of the frame or fixed-panel sash and the threshold body, and in particular to prevent moisture from penetrating the building structure. For this purpose, sealing membranes or similar materials are typically placed on the top and bottom of a connecting element. However, sealing at the contact point between the lateral bearing surface of the connecting element and the stop step of the threshold body is generally problematic.

[0004] One objective of the invention is to expand the possibilities for sealing floor sills against masonry.

[0005] The problem is solved by a floor threshold with the features of claim 1.

[0006] According to the invention, a receptacle for a sealing element is formed in the connecting element, which is open towards the lateral contact surface, wherein a spray channel for injecting a sealant is formed in the connecting element, which has an access opening not located in the lateral contact surface and opens into the receptacle.

[0007] A liquid or paste-like sealant, which subsequently hardens, can be injected into the receptacle through the injection channel. Since the access opening is located away from the contact surface, the liquid or paste-like sealant can be injected after the connecting element has been positioned against the stop. However, it is also possible to insert a solid sealing element into the receptacle before the connecting element is positioned against the stop. This means that, depending on the application, the seal against the stop can be achieved using either a solid or, alternatively, a liquid or paste-like sealant, without requiring different connecting elements. Therefore, the most suitable sealing option can be selected for each application.

[0008] Preferably, the access opening is located in the top of the connecting element. The sealant can then be easily injected into the receptacle from above – even with the connecting element already installed.

[0009] The receptacle can also be open towards the underside of the connecting element. This allows a fixed sealing element to be inserted into the receptacle from below.

[0010] One embodiment of the invention provides that the top and / or bottom of the connecting element is / are flat. This allows for large-area contact with corresponding flat surfaces of the frame, the fixed-panel sash, and / or the threshold body.

[0011] The receptacle can have at least one undercut to enable a positive-locking connection between a sealing element inserted into the receptacle and the connecting element. This results in a secure fit of the sealing element in the receptacle. Preferably, the receptacle has two opposing undercuts.

[0012] According to a specific embodiment of the invention, the receptacle has a dovetail-shaped groove extending from the underside of the connecting element towards the top, or vice versa. A complementarily shaped projection of a sealing element can be inserted into the groove, thus providing a reliable hold for the sealing element. Alternatively, the receptacle could also have a dovetail-shaped projection that interacts with a groove of the sealing element.

[0013] The threshold can have a sealing element made of an elastic material inserted into the receptacle of the connecting element, which ensures a reliable seal against the stop step. The sealing element can be designed, in particular, for detachable insertion into the receptacle. According to a specific embodiment of the invention, the sealing element is made of silicone.

[0014] The sealing element can have a sealing section designed to rest against the stop step of the threshold body and a dovetail-shaped coupling section. By inserting the dovetail-shaped coupling section into a complementarily shaped section of the receptacle, the sealing element can be detachably attached to the connecting element. The sealing section can be shaped such that it complements the contact surface in the area of ​​the receptacle's opening.

[0015] According to one embodiment of the invention, the connecting element is a single piece. Manufacturing is then particularly simple. In particular, the connecting element can be designed as a one-piece block and / or as an injection-molded part.

[0016] An alternative embodiment of the invention provides that the connecting element comprises a base body and a mounting body detachably attached to the base body, wherein the receptacle and the spray channel are formed in the mounting body. In this embodiment, it is possible to arrange the mounting body at different locations or in different orientations on the base body, depending on the application.

[0017] The stop step can have a groove extending along its longitudinal axis, with a projecting rib on the contact surface of the connecting element for engagement in the groove. This creates a positive fit between the sleeper body and the connecting element.

[0018] The invention also relates to a door system or window system, in particular a sliding door system or sliding window system, for example a lift-and-slide door system or lift-and-slide window system, comprising a frame, a fixed sash coupled to the frame, a sash movable relative to the fixed sash and a threshold for supporting the frame and the fixed sash against a building structure.

[0019] According to the invention, the threshold is designed as described above.

[0020] Due to the design of the threshold according to the invention, the sealing of the connecting element against the stop step can be achieved using a solid or, alternatively, a liquid sealing material. It is not necessary to have different connecting elements available for this purpose.

[0021] According to one embodiment of the invention, the connecting element is inserted between the surface of the sill body and a vertical frame member. In particular, the connecting element can be a frame corner connector which is arranged in the region of a trailing edge of the fixed-panel sash and transfers the weight of the vertical frame member to the sill body.

[0022] Another embodiment of the invention provides that the connecting element is inserted between the surface of the threshold body and a free leading edge section of the fixed-panel sash. Such a connecting element is generally referred to as a "center sealing block". It ensures a clean seal of the sash's leading edge at the ground and drains away any water running down the leading edge.

[0023] A door or window system according to the invention can also have a threshold with a frame corner connector and a central sealing block, wherein both the frame corner connector and the central sealing block have a receptacle and a spray channel as described above.

[0024] Further developments of the invention can also be found in the dependent claims, the following description and the accompanying drawings.

[0025] The invention is described below by way of example with reference to the drawings. Fig. Figure 1 shows a sliding door system according to the invention. Fig. Figure 2 is a perspective view of a fixed-panel area of ​​the sliding door system according to Fig. 1. Fig. Figure 3 shows a threshold of the sliding door system according to Fig. 1 in perspective single view. Fig. Figure 4 shows a frame corner connector of the floor sill according to Fig. 3 from the top. Fig. Figure 5 shows a frame corner connector of the floor sill according to Fig. 3 from the bottom. Fig. Figure 6 shows a central density block of the threshold according to Fig. 3 from the top. Fig. 7 shows the center sealing block according to Fig. 6 from the bottom.

[0026] The Fig. Figure 1 shows a sliding door system 10 with a fixed frame 11, a sliding sash 12 and a fixed sash 14, wherein the sliding sash 12 can be pushed in a conventional manner from the closed position shown in front of the fixed sash 14 to create a passage opening of the sliding door system 10.

[0027] The sliding sash 12, like the fixed sash 14, comprises a glazing 16 and a sash frame 18 surrounding the glazing 16, which here is formed from a hollow chamber profile. The fixed sash 14 has a front edge 20 facing the passage opening and an opposite rear edge 22.

[0028] The lower end of the sliding door system 10 is as shown in the Fig. 2 and Fig. 3 is recognizably formed by a threshold 24, over which the frame 11, the sliding sash 12, and the fixed sash 14 are supported on a structure not shown. The threshold 24 comprises a threshold body 26, which has a longitudinal axis 28 and is attached directly or indirectly to the structure, for example, by means of screw brackets. The threshold body 26 has a surface 30 that, when properly installed, faces upwards, from which a stop step 32 projects, extending along the longitudinal axis 28 over the entire threshold body 26. The stop step 32 forms a raised area 34 of the threshold body 26, into which a guide rail 36 for guiding the sliding sash 12 is embedded.

[0029] The trailing edge 22 of the fixed-panel wing 14 abuts a vertical beam 37 of the frame 11. The vertical beam 37 is supported on the sleeper body 26 via a first connecting element 40 in the form of a frame corner connector, with sealing membranes (not shown) preferably provided between the vertical beam 37 and the first connecting element 40, as well as between the first connecting element 40 and the surface 30 of the sleeper body 26. As shown in Fig. 3 The first connecting element 40 is identifiable as being attached to the surface 30 of the threshold body 26, for example by screwing, in such a way that it rests against the stop step 32.

[0030] The fixed-field wing 14 does not sit directly on the sleeper body 26, but via an intermediate profile 38, which is attached to the surface 30 of the sleeper body 26. As in Fig. As shown in Figure 2, the intermediate profile 38 does not extend to the front edge 20 of the fixed wing 14. Instead, in the area of ​​the front edge 20, a second connecting element 42, namely a central sealing block, is inserted between the surface 30 of the threshold body 26 and the fixed wing 14, preferably with sealing foils in between.

[0031] The Fig. 4 and Fig. Figure 5 shows the first connecting element 40 in detail. In the illustrated embodiment, the first connecting element 40 is designed as an injection-molded block. This block has a bottom surface 50 designed for placement on the surface 30 of the sleeper body 26, a top surface 51 opposite, which can be coupled to the vertical beam 37 of the frame 11, and a lateral contact surface 52 designed for bearing against the stop step 32 of the sleeper body 26. The injection-molded block can have a ribbed structure in a known manner, as can be seen from two different examples in Fig. 4 and Fig. 5 is shown.

[0032] In the area of ​​the lateral mounting surface 52, the first connecting element 40 has a recess which accommodates a receiving 54 ( Fig. 5) for a sealing element 56. As shown, the receptacle 54 is open towards the lateral contact surface 52. Furthermore, there is a connection between the receptacle 54 and the upper surface 51 in the form of a spray channel 58, which has an access opening 60 located in the upper surface 51 and opens into the receptacle 54. The receptacle 54 is also open towards the lower surface 50.

[0033] In the example shown, the access opening 60 is located near the inlet 54. In principle, however, the spray channel 58 could also extend further through the connecting element 40. Furthermore, the access opening 60 could also be located on the side or front of the connecting element 40.

[0034] As in Fig. As can be seen in section 5, the inlet 54 has a dovetail-shaped groove 62 extending from the underside 50 towards the top 51 and forming two opposing undercuts 64.

[0035] The sealing element 56, which is preferably made of an elastic material such as silicone, has a sealing section 66 designed to abut the stop step 32 of the threshold body 26 and a dovetail-shaped coupling section 68. The coupling section 68 is shaped to complement the groove 62, so that the sealing element 56 can be inserted into the receptacle 54 by inserting the coupling section 68 into the groove 62 from below, thereby creating a positive fit. Fig. Figure 4 shows the sealing element 56 in the inserted state.

[0036] The sealing section 66 has a contact surface 70 that follows the lateral contact surface 52, but as in Fig. 4 protrudes slightly beyond this. In particular, the contact surface 70 has a projecting rib 72 that follows a rib 74 of the lateral contact surface 52. In the assembled state of the first connecting element 40, the ribs 72, 74 engage in a groove 76 ( Fig. 3) a, which is provided at the stop step 32 of the sill body 26 and extends along the longitudinal axis 28.

[0037] The sealing element 56 prevents unwanted moisture from creeping along the stop step 32 into the masonry. However, it is not absolutely necessary to insert the sealing element 56 into the receptacle 54. The first connecting element 40 can also be attached to the threshold body 26 without the sealing element 56. In this case, the sealing effect can be ensured by injecting a flowable sealant into the receptacle 54 via the access opening 60 and subsequently allowing it to cure. Even in this case, the contact point between the first connecting element 40 and the stop step 32 is reliably sealed.

[0038] The Fig. 6 and Fig.The second connecting element 42, shown separately in Figure 7, is designed similarly to the first connecting element 40 with regard to its sealing function. In particular, it also has a lateral contact surface 52, a receptacle 54 open towards the lateral contact surface 52, and a spray channel 58 opening into the receptacle 54 with an access opening 60 on the top. However, unlike the first connecting element 40, the second connecting element 42 is not a single piece, but is composed of a base body 78 and a contact body 80 coupled to it. The receptacle 54 and the spray channel 58 are formed in the contact body 80. A plug connection 82 with a dovetail guide is provided for coupling the contact body 80 to the base body 78.

[0039] Because the receptacle 54 for the sealing element 56 has a fluid connection to the top 51 of the connecting element 40, 42, the installer of the threshold 24 can decide whether a solid sealing element 56 or a liquid sealant is used to seal the connecting element 40, 42 against the stop step 32. This allows the optimal sealing variant to be selected for the respective application, thereby increasing the overall sealing effect without the need to provide different types of connecting elements 40, 42.

[0040] Connecting elements 40, 42 with spray channels 58 are not only advantageous for floor thresholds for sliding doors, but also for other types of floor thresholds in the field of building technology, for example floor thresholds for revolving doors or gates.
