Description

Technical Field

[0001] The present invention relates to a sill for supporting a door or window frame and a fixed wing fan on a building body, comprising: an elongated sill body for direct or indirect fixation to the building body and having a surface from which a stop step protrudes, the stop step extending along the longitudinal axis of the sill body; and at least one connecting element to be inserted between the surface of the sill body and the bottom side of the frame or fixed wing fan, wherein the connecting element has a bottom side designed for placement on the surface of the sill body, a top side facing the frame or fixed wing fan, and a lateral abutment surface designed for abutting against the stop step of the sill body. Background Technology

[0002] Door or window sills are typically embedded in the building's floor in such a way that the surface of the sill or the surface of an intermediate profile fixed to it is as flush as possible with the floor surface. Fixed wing fans can be placed directly on the sill or on the aforementioned intermediate profile, which transfers the weight of the fixed wing fan to the sill. Guide rails can also be arranged on the sill, along which movable wing fans can be pushed in front of the fixed wing fan to release the passageway.

[0003] Connecting elements such as corner joints or intermediate sealing blocks are placed in the sills of the aforementioned type to provide coupling between the frame or fixed wing components and the sill body, and specifically to prevent moisture intrusion into the building structure. For this purpose, sealing films or similar materials are typically placed on the top and bottom sides of the connecting elements. However, sealing at the contact points between the lateral contact surfaces of the connecting elements and the stop steps of the sill body is often difficult. Summary of the Invention

[0004] The purpose of this invention is to expand the sealing possibilities of the sill relative to the masonry.

[0005] This objective is achieved by a threshold having the features of claim 1.

[0006] According to the invention, a receiving portion for a sealing element is formed in the connecting element, the receiving portion being open toward a lateral contact surface, wherein an injection channel for injecting a sealant is formed in the connecting element, the injection channel having an entry opening not located in the lateral contact surface and opening into the receiving portion.

[0007] Liquid or paste-like sealant, which subsequently hardens, can be introduced into the receiving cavity through the injection channel. Because the inlet opening is away from the contact surface, the liquid or paste-like sealant can be injected after the connecting element is abutted against the stop step. However, a solid sealing element can also be inserted into the receiving cavity before the connecting element is abutted against the stop step. In other words, depending on the application requirements, the stop step can be sealed with a solid sealing material or alternatively with a liquid or paste-like sealing material without requiring different connecting elements. Therefore, the most economical sealing method can be selected for each application.

[0008] Preferably, the inlet opening is located on the top side of the connecting element. This allows for easy injection of sealant into the receiving portion from above, even when the connecting element is already installed.

[0009] The receiving portion can also be open towards the bottom side of the connecting element. This allows the solid sealing element to be inserted into the receiving portion from below.

[0010] One embodiment of the invention specifies that the top and / or bottom sides of the connecting element are flat. This allows for large-area contact with the corresponding flat surfaces of the frame, fixed wing fan, and / or sill.

[0011] The receiving portion may have at least one undercut to achieve a form-fit connection between the sealing element inserted into the receiving portion and the connecting element. This results in the sealing element being securely fixed in the receiving portion. Preferably, the receiving portion has two opposing undercuts.

[0012] According to a particular design of the invention, the receiving portion has a dovetail groove extending from the bottom side of the connecting element toward the top side, or vice versa. A protrusion of a complementaryly shaped sealing element can be inserted into this groove, thereby achieving reliable retention of the sealing element. In principle, a dovetail-shaped protrusion can also be formed in the receiving portion, which engages with the groove of the sealing element.

[0013] The sill may have a sealing element made of elastic material that is inserted into the receiving portion of the connecting element, the sealing element ensuring a reliable seal against the stop step. This sealing element may be specifically designed to be removably inserted into the receiving portion. According to a particular design of the invention, the sealing element is made of silicone.

[0014] The sealing element may have a sealing section for abutting against the stop step of the sill and a dovetail-shaped coupling section. The sealing element can be detachably secured to the connecting element by inserting the dovetail-shaped coupling section into a complementary shaped section of the receiving portion. The sealing section may be shaped to abut against the abutting surface in the area of ​​the opening of the receiving portion.

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

[0016] Another alternative embodiment of the invention specifies that the connecting element includes a base and a stop detachably fixed to the base, wherein a receiving portion and an injection channel are formed in the stop. In this embodiment, the stop can be arranged at different locations on the base or in different orientations, depending on the application.

[0017] The stop step may have a groove extending along the longitudinal axis, wherein a protruding rib is formed on the abutment surface of the connecting element for engagement into the groove. This establishes a form fit between the sill and the connecting element.

[0018] The present invention also relates to a door system or window system, particularly a sliding door system or sliding window system, such as a lift-up sliding door system or lift-up sliding window system, having a frame, a fixed wing coupled to the frame, a movable wing relative to the fixed wing, and a sill for supporting the frame and the fixed wing on the building body.

[0019] According to the present invention, the bottom threshold is constructed as described above.

[0020] Due to the design of the sill according to the invention, the sealing of the connecting element relative to the stop step can be achieved by a solid sealing material or, alternatively, by a liquid sealing material. Therefore, there is no need to prepare different connecting elements.

[0021] According to one embodiment of the invention, a connecting element is inserted between the surface of the sill and the vertical column of the frame. This connecting element may in particular be a corner connector, disposed in the trailing edge region of the fixed wing fan and transferring the weight of the vertical column to the sill.

[0022] Another embodiment of the invention specifies that a connecting element is inserted between the surface of the sill and the free leading edge section of the fixed wing fan. This connecting element is commonly referred to as an "intermediate seal block." It ensures a clean termination of the wing fan leading edge at the bottom and guides the drainage of water flowing down the leading edge.

[0023] The door or window system according to the invention may further include a sill having a corner connector and an intermediate sealing block, wherein both the corner connector and the intermediate sealing block have a receiving portion and an injection channel as described above. Attached Figure Description

[0024] Further improvements to the invention can be obtained from the dependent claims, the following description, and the accompanying drawings.

[0025] The present invention will now be described by way of example with reference to the accompanying drawings.

[0027] Figure 2 It is based on Figure 1 A perspective view of the fixed-wing fan area of ​​the sliding door system.

[0029] Figure 4 As shown above, according to Figure 3 The corner connector of the bottom sill.

[0030] Figure 5 According to the following... Figure 3 The corner connector of the bottom sill.

[0031] Figure 6 As shown above, according to Figure 3 The middle sealing block of the bottom sill.

[0032] Figure 7 According to the following... Figure 6 The middle sealing block. Detailed Implementation

[0033] Figure 1 A sliding door system 10 is shown, comprising a fixed frame 11, a sliding wing 12, and a fixed wing 14, wherein the sliding wing 12 can be pushed from the shown closed position to the front of the fixed wing 14 in a manner known per se to release the passage opening of the sliding door system 10.

[0034] Like the fixed wing fan 14, the push-pull wing fan 12 includes a glass panel 16 and a wing fan frame 18 extending around the glass panel 16, which is formed of a hollow profile. The fixed wing fan 14 has a leading edge 20 facing the channel opening and an opposing trailing edge 22.

[0035] As from Figure 2 and Figure 3 As can be seen, the lower end of the sliding door system 10 is formed by a sill 24, through which the frame 11, sliding wing 12, and fixed wing 14 are supported on the building body (not shown). The sill 24 includes a sill body 26 having a longitudinal axis 28, which is directly or indirectly fixed to the building body, for example, by screws or angle irons. The sill body 26 has an upward-facing surface 30 when installed as specified, from which a stop step 32 protrudes, extending along the longitudinal axis 28 throughout the sill body 26. The stop step 32 forms a raised area 34 of the sill body 26, in which guide rails 36 for guiding the sliding wing 12 are embedded.

[0036] The trailing edge 22 of the fixed-wing fan 14 abuts the vertical column 37 of the frame 11. The vertical column 37 is supported on the sill 26 by a first connecting element 40 in the form of a corner connector, wherein preferably a sealing membrane (not shown) is provided between the vertical column 37 and the first connecting element 40 and between the first connecting element 40 and the surface 30 of the sill 26. Figure 3 As shown, the first connecting element 40 is fixed to the surface 30 of the sill 26 by screws, so that it rests against the stop step 32.

[0037] The fixed-wing fan 14 is not placed directly on the sill 26, but rather through an intermediate profile 38 fixed to the surface 30 of the sill 26. For example... Figure 2 As shown, the intermediate profile 38 does not extend all the way to the leading edge 20 of the fixed wing fan 14. Instead, in the region of the leading edge 20, the second connecting element 42, i.e. the intermediate sealing block, is inserted between the surface 30 of the sill 26 and the fixed wing fan 14, preferably with a sealing film in between.

[0038] Figure 4 and Figure 5 The first connecting element 40 is shown in a separate 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 for placement on a surface 30 of the sill 26, an opposing top side 51 that can be coupled to the vertical post 37 of the frame 11, and a lateral abutment surface 52 designed for abutting against a stop step 32 of the sill 26. The injection-molded block may have a ribbed structure in a conventional manner, such as… Figure 4 and Figure 5 Two different examples are shown.

[0039] In the region of the lateral contact surface 52, the first connecting element 40 has a recess that forms a receiving portion 54 for the sealing element 56. Figure 5 As shown in the figure, the receiving portion 54 is open towards the lateral contact surface 52. Furthermore, the receiving portion 54 is connected to the top side 51 in the form of an injection channel 58, which has an inlet opening 60 arranged in the top side 51 and leads into the receiving portion 54. The receiving portion 54 is also open towards the bottom side 50.

[0040] In the example shown, the inlet opening 60 is located near the receiving portion 54. In principle, the injection channel 58 can also extend through the connecting element 40 via an additional extension. Furthermore, the inlet opening 60 can also be located on the side or front of the connecting element 40.

[0041] like Figure 5 As shown, the receiving portion 54 has a dovetail groove 62 that extends from the bottom side 50 toward the top side 51 and forms two opposing undercuts 64.

[0042] The sealing element 56, preferably made of an elastic material (e.g., silicone), has a sealing section 66 designed to abut against the stop step 32 of the sill 26 and a dovetail-shaped coupling section 68. The coupling section 68 is complementary to the groove 62, such that the sealing element 56 can be inserted into the receiving portion 54 by inserting the coupling section 68 into the groove 62 from below, thereby forming a form fit. Figure 4 The sealing element 56 is shown to be in the inserted state.

[0043] The sealing section 66 has a contact surface 70 that extends along the lateral contact surface 52, but as Figure 4 The surface slightly protrudes from this surface. Specifically, the contact surface 70 has a protruding rib 72 that follows the rib 74 of the lateral abutment surface 52. In the installed state of the first connecting element 40, ribs 72 and 74 engage in the groove 76 (…). Figure 3 In the ), the groove is provided on the stop step 32 of the sill body 26 and extends along the longitudinal axis 28.

[0044] The sealing element 56 prevents moisture from undesirably entering the masonry along the stop step 32. However, it is not necessary to force the sealing element 56 into the receiving portion 54. Instead, the first connecting element 40 can also be fixed to the sill 26 without the sealing element 56. In this case, the sealing effect can be ensured by injecting a flowable sealant into the receiving portion 54 through the inlet opening 60 and then allowing it to harden. Even in this case, the contact point between the first connecting element 40 and the stop step 32 is reliably sealed.

[0045] Figure 6 and Figure 7 The second connecting element 42, shown separately, is similar in design to the first connecting element 40 in terms of sealing function. Specifically, it also has a lateral abutment surface 52, a receiving portion 54 opening toward the lateral abutment surface 52, and an injection channel 58 with a top-side inlet opening 60 leading into the receiving portion 54. However, unlike the first connecting element 40, which is a single piece, the second connecting element 42 consists of a base 78 and a stop body 80 coupled to the base. The receiving portion 54 and the injection channel 58 are formed in the stop body 80. To couple the stop body 80 to the base 78, a plug-in connector 82 with a dovetail guide is provided.

[0046] Because the receiving portion 54 has a fluid connection with the top side 51 of the connecting elements 40, 42 to the sealing element 56, the installer of the bottom sill 24 can decide whether to achieve the sealing of the connecting elements 40, 42 relative to the stop step 32 using a solid sealing element 56 or a liquid sealant. Therefore, the optimal sealing method can be selected for the corresponding application, thereby improving the overall sealing effect without the need to prepare different types of connecting elements 40, 42.

[0047] Connecting elements 40, 42 with injection channels 58 are advantageous not only for sills used in sliding doors, but also for other types of sills in the field of building technology, such as sills used in revolving doors or gates.
