Description

Technical Field

[0001] The present invention relates to a sill for supporting a frame and fixed wing of a door or window on a building body, comprising: an elongated sill body for direct or indirect fixation to the building body and having a surface; and at least one connecting element between the surface to be inserted into the sill body and the bottom side of the frame or the fixed wing, wherein the connecting element has a bottom side designed for placement onto the surface 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] In the aforementioned types of sills, connecting elements (such as frame corner connectors, intermediate sealing blocks, or similar accessories) are used to couple the components of the frame or fixed wing fan to the sill body, particularly to prevent moisture from entering the building structure. For this purpose, a sealing membrane or sealing plate is typically embedded between the connecting element and the sill body during installation. Alternatively or additionally, the joints can be sealed after installation by applying a sealant. Both of these sealing methods are tedious and labor-intensive for the personnel responsible for installation. Summary of the Invention

[0004] The purpose of this invention is to simplify the sealing of the bottom sill without compromising quality.

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

[0006] According to the invention, a groove is formed in the bottom side of the connecting element, the groove extending along the edge region of the bottom side, wherein a sealing element made of an elastic material is injection molded into the groove, wherein the sealing element adheres to the groove and protrudes from the groove, at least in an uncompressed state.

[0007] Installers do not need to carry and properly position the sealing element, as the connecting element is factory-installed with it. Because the sealing element protrudes from the groove and thus extends beyond the mating surface, it is compressed when the connecting element is pressed against the surface of the sill, thus combining with the elasticity of the sealing material to produce a particularly reliable seal. It has been proven that the corresponding injection-molded seal renders the use of a separate sealing membrane or sealing plate redundant.

[0008] Preferably, the sealing element protrudes from the groove along its entire course, thereby achieving a consistent compression allowance and a uniform sealing effect.

[0009] Sealing elements can be formed from foamed sealing materials. Foamed sealing has proven to be particularly efficient and cost-effective. Foamed sealing materials can be freely metered, tool-free, seamlessly, and precisely applied directly to the relevant components. Foaming can be chemically initiated during or after application, resulting in a resilient foam seal. The foamed sealing material can be a two-component material.

[0010] According to a particular embodiment of the invention, the sealing element is formed of a polymer material, preferably a silicone material or a polyurethane material.

[0011] The sealing element can have a circular cross-section, particularly a circular or elliptical cross-section. Such sealing elements are easily manufactured by injection molding. Preferably, the cross-section of the sealing element is uniform along the direction of the groove.

[0012] The groove can extend completely around the bottom side. That is, the groove can extend along the entire outer perimeter of the bottom side of the connecting element. This reliably prevents moisture from passing between the connecting element and the sill.

[0013] The direction of the groove does not have to be limited to the bottom side of the connecting element. For example, the groove can extend around a corner and thus also extend to the side surface of the connecting element.

[0014] It can be specified that the groove has at least one closed loop. For example, exactly one closed loop can be provided, extending near the edge of the bottom side.

[0015] According to one embodiment of the invention, the trough has two closed loops arranged on either side of a drainage channel formed in the bottom side. The drainage channel can be used to drain water towards the front side of the sill. This is particularly important in the intermediate sealing block. Through the loops arranged on either side of the drainage channel, this intermediate sealing block is securely supported on the sill and seals the sill.

[0016] A stop step may protrude from the surface of the sill body, extending along the longitudinal axis of the sill body, wherein the lateral abutment surface of the connecting element is designed to fit against the stop step of the sill body. A groove may extend into the lateral abutment surface in this case.

[0017] The bottom side of the connecting element can be flat. This allows for large-area contact with the corresponding flat surface of the sill.

[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] Because of the design of the bottom sill according to the invention, no separate sealant needs to be operated during installation, and no sealing material needs to be applied. No sealing membrane, sealing plate, or metering device needs to be prepared.

[0021] Connecting elements can be inserted between the surface of the sill and the vertical columns of the frame. In particular, the connecting elements can be frame corner connectors, which are arranged in the area of ​​the trailing edge of the fixed wing fan and transfer the weight of the vertical columns to the sill.

[0022] Alternatively, a connecting element can be inserted between the surface of the sill and the free leading edge section of the fixed wing fan. This connecting element is often referred to as an "intermediate seal." It ensures a clean termination of the wing fan leading edge at the ground and drains away runoff along the leading edge.

[0023] The door or window system according to the invention may also include a sill with a frame corner connector and an intermediate sealing block, wherein both the frame corner connector and the intermediate sealing block have grooves and sealing elements as described above, which are injection-molded into the grooves.

[0024] The present invention also relates to a method for manufacturing a sill, the sill being configured to support a door or window frame and a fixed sill to a building body, particularly a sill having the design described above, the method comprising the following steps:

[0025] (i) Providing an elongated sill body for direct or indirect attachment to the building body and having a surface, (ii) Provide at least one connecting element between the surface of the sill to be inserted and the underside of the frame or fixed wing fan, and have a underside designed for placement onto the surface of the sill, wherein a groove is formed in the underside of the connecting element, the groove extending along an edge region of the underside. (iii) Inject the elastic sealing material into the groove. (iv) Place the connecting element onto the surface of the sill body with the sealing material first, and (v) Secure the connecting element to the sill while compressing the sealing material.

[0026] The sealing elements are manufactured and correctly placed before installation, thus reducing the workload of the installers.

[0027] Preferably, the sealing material is injection molded in a liquid or paste state, for example by an automatic metering device.

[0028] Sealing materials can include polymer materials, especially silicone or polyurethane materials.

[0029] During or after injection molding, the sealant can undergo "curing," a chemical reaction that transforms the liquid or paste-like sealant into a substantially solid and shape-stable sealing element. However, this "curing" should not be interpreted as the resulting sealing element being rigid in the sense of being "inelastic." Attached Figure Description

[0030] Further improvements to the invention can be obtained from the dependent claims, the following description, and the accompanying drawings.

[0031] The present invention will now be described by way of example with reference to the accompanying drawings.

[0033] Figure 2 It is based on Figure 1 A perspective view of the fixed-wing fan area of ​​the sliding door system.

[0034] Figure 3 Shown in a separate perspective view according to Figure 1 The bottom sill of the sliding door system.

[0035] Figure 4 According to the following... Figure 3 The bottom sill frame corner connector.

[0036] Figure 5 According to the following... Figure 3 The middle sealing block of the bottom sill. Detailed Implementation

[0037] 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.

[0038] 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.

[0039] As from Figure 2 and Figure 3As 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.

[0040] The trailing edge 22 of the fixed-wing fan 14 abuts the vertical post 37 of the frame 11. The vertical post 37 is supported on the sill 26 by a first connecting element 40 in the form of a corner connector. 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.

[0041] 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.

[0042] Figure 4 The first connecting element 40 is shown in a separate view from below. In the illustrated embodiment, the first connecting element 40 is designed as an injection-molded block. The injection-molded block has a bottom side 50 designed for placement on the surface 30 of the sill 26 and a lateral abutment surface 52 designed for abutting against the stop step 32 of the sill 26. In the illustrated embodiment, the bottom side 50 of the first connecting element 40 is flat.

[0043] A channel in the form of a groove 54, opening toward the bottom side 50 of the first connecting element 40, is also formed therein, extending at the edge 56 of the bottom side 50. That is, the groove 54 forms a recess in the bottom side 50 of the first connecting element 40. This recess may have a semi-circular cross-section.

[0044] As shown, the groove 54 extends completely around the bottom side 50 and has an extension 58 that also opens toward the laterally abutting surface 52. A sealing element 62, formed by an elongated segment 60 and made of an elastic material, is injection molded into the groove 54. This elastic material can be a foamed polymer material, such as silicone- or polyurethane-based. The injection-molded material adheres to the groove 54 and protrudes from the groove 54 in its uncompressed initial state. In the illustrated embodiment, the sealing element 62 has a circular cross-section.

[0045] With the extension 58 included, the slot 54 is therefore designed as a closed loop. However, the sealing element 62 has an interruption in the region of the extension 58 to provide structural space for a separate sealing element (not shown) to be inserted into the extension 58.

[0046] When installing the sill 24, the first connecting element 40 is placed on the surface 30 of the sill body 26 and preferably screwed onto that surface. Here, the sealing element 62 is compressed, thereby providing a reliable seal. This prevents moisture from undesirably seeping in through the joint between the sill body 26 and the first connecting element 40.

[0047] Figure 5 The sealing design of the second connecting element 42 relative to the surface 30 of the sill 26 is similar to that of the first connecting element 40. Specifically, the second connecting element also has a bottom side 50 and a lateral abutment surface 52. A drainage channel 66, opening towards the bottom side 50, extends from the lateral abutment surface 52 through the entire second connecting element 42. On both sides of the drainage channel 66, recesses 68 are formed in the bottom side 50, these recesses generally forming as shown in the diagram. Figure 4 The first connecting element 40 shown has a groove 54'. The sealing element 62' is injection molded into the groove 54' from an elastic material. According to the two-part design of the groove 54', the sealing element is not a one-piece first connecting element 40, but consists of two separate parts 71 and 72. As shown, parts 71 and 72 form a closed loop.

[0048] In order to manufacture Figure 2 and Figure 3 The bottom sill 24 shown initially provides a sill body 26, a first connecting element 40, a second connecting element 42, an intermediate profile 38, and a guide rail 36. Subsequently, sealing material is injected into the groove 54 of the first connecting element 40 and the groove 54' of the second connecting element 42 using an automatic metering device. A predetermined reaction time is then allowed, as needed, until the injected sealing material has fully reacted, particularly foamed, and formed elastic sealing elements 62, 62'. The reaction can, in principle, proceed very quickly, to the point that it actually occurs during injection molding.

[0049] Next, the first connecting element 40 and the second connecting element 42 are placed on the surface 30 of the sill 26 in a manner that seals 62 and 62' come first, and then fixed thereon. The intermediate profile 38 is also fixed to the sill 26. The guide rail 36 is similarly fixed to the sill 26. The fixing steps can be performed during the installation process, during which neither positioning sealing film nor joint sealant spraying is required.

[0050] The foamed sealing elements 62, 62' are advantageous not only for sliding door sills, but also for other types of sills in the field of building technology, such as sills for revolving doors or gates.
