Description

[0001] speed bump

[0002] The invention relates to a threshold for supporting a frame and a fixed panel leaf of a door or window on a building structure, with an elongated threshold body which is intended for direct or indirect fastening to the building structure and has a surface from which a stop step projects, which extends along a longitudinal axis of the threshold body, and with at least one connecting element to be inserted between the surface of the threshold body and an underside of the frame or of the fixed panel leaf, wherein the connecting element has an underside designed to be placed on the surface of the threshold body, an upper side to be turned towards the frame or the fixed panel leaf and a lateral contact surface designed to bear against the stop step of the threshold body.

[0003] 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 sill or an intermediate profile attached to it is as flush as possible with the surface of the floor slab. The fixed panel sash can rest directly on the sill or on the aforementioned intermediate profile, which transfers the weight of the fixed panel sash to the sill. A guide rail can also be arranged on the sill, along which a movable sash can be slid in front of the fixed panel sash to create a passage.

[0004] Connecting elements such as frame corner connectors or central sealing blocks are intended for thresholds of the type mentioned above to provide a connection between the components of the frame or fixed-panel sash and the threshold body, and in particular to prevent moisture penetration into the building structure. For this purpose, sealing foils or similar materials are commonly placed on the top and bottom of a connecting element. However, sealing the contact point between the lateral contact surface of the connecting element and the stop step of the threshold body is generally difficult.

[0005] It is an object of the invention to expand the possibilities for sealing floor thresholds against the masonry.

[0006] The problem is solved by a threshold having the features of claim 1.

[0007] According to the invention, a receptacle for a sealing element is formed in the connecting element, which receptacle is open towards the lateral contact surface, wherein an injection channel for injecting a sealing agent is formed in the connecting element, which injection channel has an access opening not located in the lateral contact surface and opens into the receptacle.

[0008] A liquid or pasty sealant, which is then to be cured, can be introduced into the receptacle through the injection channel. Since the access opening is located away from the contact surface, the liquid or pasty sealant can be injected after the connecting element has been placed against the stop step. However, it is also possible to insert a solid sealing element into the receptacle before the connecting element is placed against the stop step. This means that, depending on the application, the seal to the stop step can be achieved using a solid or, alternatively, a liquid or pasty sealing material, without the need to provide different connecting elements. The most suitable sealing variant can therefore be selected for each application. The access opening is preferably located in the top side of the connecting element.The sealant can then be easily injected into the receptacle from above - even when the connecting element is already installed.

[0009] The receptacle can also be open toward the bottom 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 enables extensive contact with corresponding flat surfaces of the frame, the fixed panel sash, and / or the sill body.

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

[0012] According to a special embodiment of the invention, the receptacle has a dovetail-shaped groove extending from the underside of the connecting element toward the top, or vice versa. A complementarily shaped projection of a sealing element can be inserted into the groove, thus ensuring a reliable hold of the sealing element. In principle, a dovetail-shaped projection could also be formed in the receptacle, which interacts with a groove of the sealing element.

[0013] The threshold can have a sealing element made of an elastic material inserted into the connecting element's receptacle, 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 special embodiment of the invention, the sealing element is made of silicone.

[0014] The sealing element can have a sealing section designed to engage the stop step of the sleeper 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 releasably attached to the connecting element. The sealing section can be shaped such that it complements the contact surface in the area of ​​the opening of the receptacle.

[0015] According to one embodiment of the invention, the connecting element is made of one piece. This makes manufacturing 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, however, provides that the connecting element comprises a base body and a contact body detachably attached to the base body, wherein the receptacle and the injection channel are formed in the contact body. In this embodiment, it is possible to arrange the contact body at different locations or in different orientations on the base body depending on the application.

[0017] The stop step may have a groove extending along the longitudinal axis, with a projecting rib formed on the contact surface of the connecting element for engagement in the groove. This creates a positive connection 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, with a frame, a fixed panel sash coupled to the frame, a sash movable relative to the fixed panel sash and a floor sill for supporting the frame and the fixed panel sash on a building structure.

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

[0020] Due to the inventive design of the threshold, the sealing of the connecting element against the stop step can be achieved using a solid or, alternatively, a liquid sealing material. This eliminates the need to keep different connecting elements on hand.

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

[0022] Another embodiment of the invention provides for the connecting element to be inserted between the surface of the threshold body and a free leading edge section of the fixed-field wing. Such a connecting element is generally referred to as a "center sealing block." It ensures a clean seal between the wing's leading edge and the ground and diverts water running down the leading edge.

[0023] A door or window system according to the invention can also comprise a threshold with a frame corner connector and a center sealing block, wherein both the frame corner connector and the center sealing block have a receptacle and a spray channel as described above. Further developments of the invention can also be found in the dependent claims, the following description, and the accompanying drawings.

[0024] The invention is described below by way of example with reference to the drawings.

[0026] Fig. 2 is a perspective view of a fixed panel wing area of ​​the sliding door system according to Fig. 1 .

[0027] Fig. 3 shows a threshold of the sliding door system according to Fig. 1 in a perspective individual view.

[0028] Fig. 4 shows a frame corner connector of the threshold according to Fig. 3 from above.

[0029] Fig. 5 shows a frame corner connector of the threshold according to Fig. 3 from below.

[0030] Fig. 6 shows a central sealing block of the threshold according to Fig. 3 from above.

[0031] Fig. 7 shows the central sealing block according to Fig. 6 from below.

[0032] Fig. 1 shows a sliding door system 10 with a stationary frame 11, a sliding sash 12, and a fixed sash 14. The sliding sash 12 can be pushed in a conventional manner from the illustrated closed position in front of the fixed sash 14 to expose a passage opening in the sliding door system 10. Like the fixed sash 14, the sliding sash 12 comprises a glazing 16 and a sash frame 18 surrounding the glazing 16, which frame is formed here from a hollow chamber profile. The fixed sash 14 has a front edge 20 facing the passage opening and an opposite rear edge 22.

[0033] The lower end of the sliding door system 10 is formed, as can be seen in Figs. 2 and 3, by a threshold 24, via which the frame 11, the sliding sash 12 and the fixed panel sash 14 are supported on a structural member not shown. The threshold 24 comprises a sill body 26 which has a longitudinal axis 28 and is fastened directly or indirectly to the structural member, for example by means of screw angles. The sill body 26 has a surface 30 which, when properly installed, faces upwards and from which a stop step 32 protrudes, extending along the longitudinal axis 28 over the entire sill body 26. The stop step 32 forms a raised region 34 of the sill body 26, into which a guide rail 36 for guiding the sliding sash 12 is embedded.

[0034] The rear edge 22 of the fixed panel wing 14 borders on a vertical strut 37 of the frame 11. The vertical strut 37 is supported on the sill body 26 via a first connecting element 40 in the form of a frame corner connector, wherein sealing films (not shown) are preferably provided between the vertical strut 37 and the first connecting element 40 and between the first connecting element 40 and the surface 30 of the sill body 26. As can be seen in Fig. 3, the first connecting element 40 is fastened to the surface 30 of the sill body 26, for example by screwing, such that it rests against the stop step 32. The fixed panel wing 14 does not sit directly on the sill body 26, but via an intermediate profile 38 which is fastened to the surface 30 of the sill body 26. As shown in Fig. 2, the intermediate profile 38 does not reach the leading edge 20 of the fixed field wing 14.Rather, 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 field wing 14, preferably with sealing foils interposed.

[0035] Figs. 4 and 5 show the first connecting element 40 in a single view. In the illustrated embodiment, the first connecting element 40 is designed as an injection-molded block. This block has a bottom side 50 designed to be placed on the surface 30 of the sleeper body 26, an opposite top side 51 that can be coupled to the vertical beam 37 of the frame 11, and a lateral contact surface 52 designed to bear against the stop step 32 of the sleeper body 26. The injection-molded block can have a ribbed structure in a known manner, as shown in two different examples in Figs. 4 and 5.

[0036] In the area of ​​the lateral contact surface 52, the first connecting element 40 has a recess that forms a receptacle 54 (Fig. 5) for a sealing element 56. As shown, the receptacle 54 is open toward the lateral contact surface 52. Furthermore, there is a connection between the receptacle 54 and the upper side 51, namely in the form of a spray channel 58, which has an access opening 60 arranged in the upper side 51 and opens into the receptacle 54. The receptacle 54 is also open toward the underside 50.

[0037] In the example shown, the access opening 60 is located close to the receptacle 54. In principle, however, the injection channel 58 could also extend a further distance through the connecting element 40. Furthermore, the access opening 60 could also be located on the side or front of the connecting element 40.

[0038] As can be seen in Fig. 5, the receptacle 54 has a dovetail-shaped groove 62 which extends from the underside 50 towards the top side 51 and which forms two opposite undercuts 64.

[0039] The sealing element 56, which is preferably made of an elastic material such as silicone, has a sealing section 66 designed to engage the stop step 32 of the sill body 26 and a dovetail-shaped coupling section 68. The coupling section 68 is shaped complementarily to 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. 4 shows the sealing element 56 in the inserted state.

[0040] The sealing section 66 has a contact surface 70 that follows the lateral contact surface 52, but protrudes slightly beyond it, as can be seen in Fig. 4. In particular, the contact surface 70 has a protruding 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) provided on the stop step 32 of the sleeper body 26 and extending along the longitudinal axis 28.

[0041] 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. Rather, the first connecting element 40 can also be attached to the sill body 26 without the sealing element 56. The sealing effect can be ensured by injecting a flowable sealant into the receptacle 54 via the access opening 60 and subsequently curing it. In this case, too, the contact point between the first connecting element 40 and the stop step 32 is reliably sealed.

[0042] The second connecting element 42, shown individually in Fig. 6 and 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 an injection channel 58 opening into the receptacle 54 with an access opening 60 on the top. However, the second connecting element 42 is not one-piece like the first connecting element 40, but is composed of a base body 78 and a contact body 80 coupled to it. The receptacle 54 and the injection channel 58 are formed in the contact body 80. A plug-in connection 82 with a dovetail guide is provided for coupling the contact body 80 to the base body 78.

[0043] Because the receptacle 54 for the sealing element 56 has a fluid connection to the upper side 51 of the connecting element 40, 42, the installer of the threshold 24 can decide whether to use a solid sealing element 56 or a liquid sealant to seal the connecting element 40, 42 against the stop step 32. This allows the optimal sealing variant for the respective application to be selected, thus increasing the overall sealing effect without the need to provide different types of connecting elements 40, 42.

[0044] Connecting elements 40, 42 with spray channels 58 are advantageous not only for thresholds for sliding doors, but also for other types of thresholds in the field of building technology, for example, thresholds for revolving doors or gates. Reference symbols:
