The invention relates to a window or a door with such a threshold connector.

Description

The invention relates to a threshold connector for fastening a threshold profile between the vertical frame profiles of a window or door. The invention also relates to a window or a door, at least comprising a blind frame that can be firmly connected to masonry and has a stop seal and / or a center seal, a pivoting and / or tilt and turn sash connected to it and a threshold connector, which is connected between the rebate-side inner surface of the window frame and attached to the end face of the threshold profile and firmly connected to the adjacent elements.

Doors, in particular side entrance doors and revolving doors, typically have a threshold connector in the transition area from the threshold to the vertical door pillar, which connects the threshold and the frame to one another in a stable manner.

Elements are known as threshold connectors which serve to attach the threshold profile simply and solidly between the particularly vertical frame profiles. A distinction is made between two connection options:
In one variant, the frame profiles are placed on the horizontally running threshold. In order to be able to fit exactly, it is necessary that the front of the vertical plastic frame profile is milled to match the surface profile / surface contour of the threshold so that the two profiles can be accurately positioned. The step areas of the threshold consist, for example, of a combination of heavy-duty aluminum profiles and plastic profiles. The plastic profiles, which are mostly made of PVC, are used for thermal separation.

The other variant provides that the threshold is used in the clear dimension, that is, between the two vertically extending frame profiles. For this purpose, a threshold connector is coupled at the end to the threshold and firmly connected by means of screws. Therefor the threshold is cut at right angles and coupled with the threshold connector, which is mostly made of PVC. The threshold connector forms the connection to the threshold on one side and is cut straight.

On the other hand, it forms the connection to the outer frame and is milled for a flush or form-fitting connection according to the contour of the outer frame profile. In this case, the threshold connector takes on the function of contour compensation and connects the horizontally running threshold with the vertically running outer frame profile.

Alternatively, the threshold can be placed directly between the vertical frame profiles in accordance with the clearance width. For this purpose, a contour milling is required to adapt to the rebate surface of the frame profiles. In this variant, the threshold connector is used exclusively to connect the threshold to the frame profile and is primarily made of die-cast zinc or plastic.

The contour of the threshold connector must also be adapted at its left and right end, which is in each case on the front side of the vertical frame profiles. For this purpose, plastic threshold connectors are used. These are injection-molded parts that are connected on one side to the smoothly cut threshold and on the other side form the contour-correct connection to the vertical frame profile. This pre-assembled threshold is pushed into the frame rebate of the open door and attached to the vertical frame profile.

Frame profile cross-sections can vary depending on their different purposes. The disadvantage of the previous application is that the threshold connectors in different embodiments, e.g. must be kept ready for frame profiles of rebate seal (AD) and center seal systems (MD). The stop seal in the frame profile is mandatory. It seals the circumferential, external gap between the sash and the frame in the closed window position against wind and rain. The center seal can optionally provide additional tightness in addition to the stop seal between the sash and frame. Center sealing systems thus have a first sealing plane on the inner stop in the frame, the second is shifted to the center of the frame rebate. The choice of the respective sealing system is freely chosen by the respective manufacturers and can vary depending on the application.

In any case, there is an adequate threshold connector for every frame profile cross-section required, which must form a matching negative contour of its contact surface facing the frame profile in the connection area.

The publication DE 37 27 663 A1 describes a method for connecting a frame profile with a threshold profile. For this purpose, the frame profile and the threshold profile are cut to length at right angles and connected to one another using a special threshold connector. The threshold connector has a flat sealing surface corresponding to the outer contour of the frame profile on its upper side and a shape corresponding to the threshold profile on its lower side. The threshold connector is preferably connected to the frame profile by screwing and / or gluing, while the threshold connector is initially positively connected to the threshold profile by being clipped on or pushed on. After aligning the frame profiles, the threshold connector can be connected to the threshold profile in a force-locking manner by means of a screw connection.

The disadvantage of this type of connection is that the cross-section of the threshold connector must have the same contour as the frame profile. If the frame profile changes, this inevitably entails a change in the threshold connector. Since threshold connectors are usually injection molded parts, new, costly injection molding tools are required for contour variants. A new injection mold is always required to manufacture the adequate threshold connector. This inevitably increases both the investment costs on the production side and an increase in storage capacities.

The object of the invention is thus to provide a universal threshold connector which forms a precisely fitting connection to different frame profiles, in particular those different types of frame profiles that differ from one another in cross-section, but are at least designed the same for the most part. The differences are therefore to be classified as small compared to the overall cross-section.

This object is achieved with a threshold connector according to the features of claim 1. Advantageous embodiments of the invention emerge from the subclaims. The wording of all claims is hereby incorporated by reference into the content of this description.

The use of the singular is not intended to exclude the plural, and vice versa Has to apply unless otherwise indicated.

The advantage of the invention is that a threshold connector base body for several types, in particular at least two types of frame profiles, e.g. for a frame profile with a stop seal and center seal, as well as without a center seal, i.e. only with a stop seal.

In the case of a frame profile without a center seal, the contact surface of the threshold connector base body is secured by an insertable, exchangeable element, e.g. is inserted laterally on / into the threshold connector base body, supplemented, in particular filled. The contact surface of the threshold connector according to the invention facing the rebate of the frame profile can thus be adapted to the surface profile / contour of the frame rebate of different types of frame profiles, i.e. preferably to frame profiles only for a stop seal and frame profiles for a stop seal and a center seal. The cross-sections of these frame profiles thus preferably differ only in the portion of the cross-section which is assigned to the central seal and are otherwise identical in design.

This means that it is no longer necessary to keep different variants of threshold connectors for different frame profiles. Rather, a first sleeper connector can already be formed from the sleeper connector base body alone and a second sleeper connector from the sleeper connector base body with an inserted interchangeable element. The invention can also provide to form a set from a threshold connector base body and at least one interchangeable element, from which a required threshold connector can optionally be formed. This reduces storage capacities and reduces the costs for tool manufacture; in this case, the provision of additional, complex injection molds.

According to the invention, it is proposed that the threshold connector base body, which is uniformly designed from a molded part for several types of frame profile, optionally both for a frame profile of a stop seal system (AD) and for a frame profile of a center seal system (MD), namely without an interchangeable element or by inserting an interchangeable element, can be used. Using a universal threshold connector body, the simple insertion of the interchangeable element enables the threshold to be individually designed for different sealing systems.

The invention is a special threshold solution for processors who classic milling of the frame profile, do not want. It is a special threshold connector that allows the threshold to be processed with the outer frame profile without milling the frame.

The threshold has a threshold connector in the transition area to the vertical frame profile, which connects the threshold and the frame profile to one another in a stable manner.

For this purpose, the threshold connector is attached as the sole threshold connector base body or, alternatively, as a threshold connector base body with an inserted interchangeable element, at the end of the threshold, preferably on its end face cut at right angles to the longitudinal direction, and can be connected to the threshold, e.g. be connected with screws. This pre-assembled, ready-made threshold is positioned in the frame rebate of the window frame and, for example, firmly screwed to the vertical window frame profile with fastening straps.

This design now enables the uniformly designed threshold connector body to be used either as a threshold connector for a center seal system (MD) or, by inserting an insertable interchangeable element, as a threshold connector for a stop seal system (AD).

In one possible embodiment e.g. On the outside of the building, the threshold connector (base body) in the center sealing system has a recess for the frame overlap, which interacts positively and flush with the contour of the frame rebate. In the case of the stop and center seal system, the extruded seals are preferably removed from the frame profile in the contact area of the threshold connector. The contour or the course / the relief of the contact surface of the threshold connector corresponds to the inner contour of the plastic frame profile, after removal of the extruded seals, in the contact area of the two components. The contour of the contact surface of the plastic outer frame profile is preferably formed by the glazing bead groove, rebate surface, center sealing web (if present) and outer frame overlap.

The rabbet-side contact surface of the threshold connector according to the invention preferably corresponds in each case to the negative shape of the rabbet surface of the correspondingly associated frame profile.

The threshold connector base body is designed for the contour with the greatest space requirement of one of the frame profile types, here for example the frame profile of a center seal system. By inserting the interchangeable element, it can be adapted to a contour with a smaller space requirement of another frame profile type, here for example the stop seal system without a center seal.

If a door is to be erected only with a stop seal system, the threshold connector base body can accordingly be supplemented with an interchangeable element to form the then suitable threshold connector.

The interchangeable element is preferably also a molded part produced by injection molding, just like the threshold connector base body. It forms or includes the negative shape for the recess on the threshold connector base body for the center sealing web, so that, if it is a stop system, it can be inserted precisely into the recess and fills it. The gap that otherwise arises in the threshold connector body due to the lack of a central sealing bar is closed precisely by the interchangeable element.

In a preferred embodiment, the interchangeable element has an attached first guide web, in particular a long guide web, and a second guide web, in particular a comparatively short guide web, which are arranged parallel to one another. The interchangeable element can be pushed into the threshold connector base body, preferably on the contact surface, with an exact fit by means of the guide webs, and in this way fill the recess.

The interchangeable element can optionally also be retrofitted from above, i.e. be used parallel to the longitudinal direction of the frame profile after assembly in the sense of a shaped plug. Such a molded plug preferably consists of an elastic soft plastic, for example of APTK, and is more preferably provided with a collar. In comparison, the interchangeable element takes on the function of a placeholder. A flush contour along the frame fold is created by inserting the interchangeable element as a filler body.

Depending on the sealing system, the threshold connector according to the invention is made up of a threshold connector base body with or without an interchangeable element and is attached to the front side of the threshold. The pre-assembled complete threshold is inserted between the vertical frame profiles during installation and preferably firmly connected to these to form a frame.

In Figure 1 a threshold connector base body 10 according to the invention is shown. The threshold connector body 10 has the shape of an angular profile, consisting of a vertical and a horizontal leg. This threshold connector body 10 can be used alone as a threshold connector according to the invention.

The vertical leg of the threshold connector base body 10 comprises an upwardly pointing fastening tab 12 or is formed solely by this. In the contact surface of the threshold connector 10 facing or to be assigned to the frame, next to e.g. On the building side next to the fastening tab 12 there is a recess 11 for a central sealing web 31 ', in particular the web on the frame profile without the central seal 31. On the other side, in particular on the outside of the fastening tab 12, there are two positioning cams 19 arranged vertically one below the other on the contact surface facing the window profile or only one, in particular that does not protrude beyond the system level 10 '. The ends of the positioning cams 19, the tab 12 and the outer recess wall pointing towards the frame profile can thus lie in this contact plane. Thus, the threshold connector base body 10 preferably has no elements which protrude beyond this plane 10 ′ in the direction of the frame profile.

The positioning cams 19 serve as an assembly aid and for correct positioning when the preassembled threshold 40 is inserted. The positioning cams 19 engage in the glass bead groove 39 of the window frame. The contact surface preferably has no sealing surface on the frame side.

The horizontal leg of the threshold connector base body 10 corresponds in its cross-sectional profile to the profiling of the threshold profile and preferably has at least one vertically extending sealing surface 15 on the threshold-side end face, which, for example, with a glued-on, e.g. squeezable sealing element is provided. The threshold connector base body 10 is provided with a groove 18 for an attachable, e.g. provided with a clip-in cover and on the sleeper side has a flat fixing element 13, which is preferably equipped with two guide lugs 13 ', 13 "which extend on both edges along the lateral contour of the fixing element 13. The fixing element 13 engages at the front in the groove 42 of the base profile 41 of the threshold profile 40 and is pushed in according to its length up to the stop and is fixed against lifting. On the side, in particular on the outside of the building, the threshold connector base body 10 has a recess 17 for the frame overlap 34, which is form-fitting and flush with the contour of the frame rebate Rollover cooperates.

On the surface, in particular the surface on the outside of the building, the threshold connector base body 10 has a drainage channel, in particular one which is formed at an angle Drainage channel 14 which, when assembled with the threshold, preferably forms a continuous extension. According to a particularly advantageous embodiment of the invention, the threshold connector body 10 formed from a molded part is penetrated with screw holes 16 to 16 "', in particular in the longitudinal direction of the threshold profile. Screw holes 16", 16'"are provided in the vertically extending leg for fixing to the frame profile 30 and screw holes 16, 16 'are provided in the horizontally extending leg for attachment to the threshold 10. A continuous screw connection of the frame profile, threshold connector base body and threshold profile is also conceivable.

The Figures 2A-2F represent in the classic two-dimensional views the structural details of the sleeper connector base body or a sleeper connector 10 formed by it without an interchangeable element.

Figure 3A shows the interchangeable element 20 in a perspective view Figures 3B - 3G represent the classic two-dimensional views. The interchangeable element 20 is, for example, also a molded part produced by injection molding, just like the threshold connector base body 10. It comprises an element with the negative shape for the recess for the center sealing web 31 'so that it can, if it is is a stop means sealing system, inserts a precise fit into the recess 11 and fills it. The guide webs 22, 23 are integrally formed on this element with the negative shape.

In the embodiment shown, the interchangeable element 20 has a long guide web 22 and a comparatively short guide web 23, which are arranged parallel to one another, wherein the interchangeable element can be pushed into the threshold connector base body 10 with an exact fit by means of the guide webs 22, 23 and thus the recess 11 replenishes. The contact surface 21 of the interchangeable element, after being inserted into the sleeper connector base body, forms part of the contact surface of the then formed sleeper connector. A flush contour along the frame fold 34 is thus produced by inserting the interchangeable element 20 as a filler body.

Figure 4 shows the threshold connector base body 10 between the frame profile 30 and threshold profile 40 in a perspective view and Figure 5 shows the threshold connector body 10 between the frame profile 30 with center seal and the threshold profile 40 in the assembled state.

Figure 6 forms the threshold connector body 10 with interchangeable element 20 between the frame profile 30 'only with a stop seal and threshold profile 40 in a perspective view from and Figure 7 shows the threshold connector base body 10 with interchangeable element 20 between frame 30 'only with stop seal and threshold profile 40 in the assembly.

The frame profiles in the stop and center seal system 30, 30 'are e.g. formed from hollow chamber profiles with inlaid reinforcing steel 37. The threshold profile 40 is integrated at the end between the vertically arranged frame profiles 30 or 30 '. The threshold profile 40 consists e.g. from a step profile 43 made of aluminum, which is coupled or clipped to a base profile 41 made of PVC. This combination of the threshold profiles is suitable, for example, for arranging an attachable cover (not shown) on the base profile 41.
