Description

[0001] The present invention relates to a protective element for use on a window system or a door system.

[0002] Various protection and covering options for use in or on window and door systems are already known from the state of the art. Watertightness is a particularly important aspect in window and door construction. The transition between a window and a window sill, or between a door and a cornice covering, is particularly vulnerable to the ingress of water and dirt particles, and sealing and protecting these areas is very costly. The problem with existing solutions in this context is that the installation effort and manufacturing costs required to achieve better protection in the window and / or door area are high.

[0003] The object of the present invention is therefore to provide better protection for a window or door system, in particular against the penetration of liquid and dirt particles, while keeping the manufacturing costs and installation effort as low as possible.

[0004] These objects are achieved with a protective element according to claim 1, as well as a window or door system according to claim 15.

[0005] According to the invention, a protective element for use on a door or window leaf is provided, comprising a front section and a base section, wherein the front section extends substantially longitudinally or parallel to a front plane, wherein the base section extends substantially longitudinally or parallel to a base plane, wherein the front plane and the base plane are transverse to one another, wherein the protective element has a holding section which is fixed or formed on the base section and has an adhesive surface. The protective element is a component, preferably made in one part or several parts, which has at least a front section and a base section. The front section extends substantially along or parallel to a front plane, wherein "substantially" in this context means that the predominant part, particularly preferably 70-95% of the total extension of the front section runs parallel to the front plane.Analogously, the base section extends essentially parallel to or along a base plane, whereby here too the definition of essentially means that the predominant part of the base section extends parallel to the base plane. The front section and the base section are thus essentially flat and have a significantly greater extension parallel to the respective plane (front plane, base plane) compared to their cross-sectional thickness orthogonal to the respective plane. Advantageously, the front section and the base section are each cuboid-shaped, i.e. have a rectangular geometry projected into the respective plane (front plane, base plane). In addition, a holding section is formed on the base section either in one piece or integrally with the base section or is fixed to the base section. The holding section serves in particular to fix the protective element to a frame of a door or window.Furthermore, the holding section also ensures a seal between the protective element and the frame of the door or window. In a first preferred embodiment, the holding section can be designed as a double-sided adhesive tape. Alternatively, the holding section can preferably be designed as an adhesive layer applied to the protective element using a two-component injection molding process. The front section of the protective element extends transversely, particularly preferably perpendicular to an upper side of the base section. When installed, the front section advantageously projects downwards from the lower edge of the frame and thus covers the area below the frame of the door or window. This area, in particular the corner area of ​​a frame and the edge area of ​​the window sill or cornice covering arranged below the frame, is also called the trades hole.The protective element according to the present invention is specifically designed to cover this access hole, thus effectively preventing liquids or foreign objects from entering the access hole. At the same time, the simple attachment of the support element to the window frame using the retaining section and the adhesive surface provided on the retaining section allows for particularly simple installation of the support element. Furthermore, the manufacturing costs are very low, particularly when the protective element is designed as an injection-molded component, particularly made of weatherproof plastic.

[0006] In one embodiment, the protective element has a side section, wherein the side section extends substantially longitudinally or parallel to a side plane, and wherein the side plane is orthogonal to the front plane and the floor plane. In addition to the front section and the floor plane, a side section is advantageously provided which extends substantially perpendicular to the floor section, such that the side plane is orthogonal to the front plane and the floor plane. The side section ensures that the lateral region of the window frame or door frame above the corner region of the window or door frame is covered. Furthermore, the side section is also suitable for achieving a more stable attachment of the support element to the frame, in particular in the case in which the holding section is also formed or fixed on the side section.Analogous to the front section and the base section, the side section also extends essentially flat and predominantly parallel to the side plane. Advantageously, the smaller extension length of the side section, measured parallel to the side plane, is approximately the same length, or preferably the same length, as the smaller extension length of the base section, measured parallel to the floor plane. This feature preferably ensures uniform coverage on both the side and underside of the frame of a door or window, and a large mounting surface for the protective element.

[0007] In one embodiment, the retaining section is additionally fixed or formed on the side section. In this way, the retaining section ensures that the protective element is secured, in particular adhesively secured, to the window or door frame not only in the area of ​​the base section but also in the area of ​​the side section.

[0008] In one embodiment, the base section and the side section are designed as a single piece. To simplify the manufacture of the support element, the base section and the side section are designed as a single piece, which avoids additional assembly work for joining the side section and the base section. In contrast and alternatively, the side section and the base section can also be designed as individual elements, which are available together, for example, by means of a clip connection. The multi-part design of the protective element permits a modular construction, which, in particular while retaining certain individual parts, allows for a greater variety of variants. This can reduce manufacturing and assembly costs for a particularly large number of different window and door systems, which would otherwise require a large number of completely differently designed, one-piece protective elements.

[0009] In one embodiment, the holding section has a first holding part and a second holding part, wherein the first holding part is fixed or formed on the side section and wherein the second holding part is fixed or formed on the base section. In a first embodiment, the holding parts of the holding section are formed integrally with one another, for example as a double-sided adhesive tape which is fixed to both the side section and the base section. Alternatively, the first holding part and the second holding part can also be designed as separate adhesive elements, which allows, for example, a different thickness in the region of the base section and in the region of the side section.

[0010] In one embodiment, the front section has a front length measured parallel to the cutting edge between the side plane and the front plane, which is a multiple, preferably 5 to 30 times, its cross-sectional thickness. In the event that the protective element does not have a side section, the side plane is defined as the plane that is both orthogonal to the floor plane and orthogonal to the front plane. When the protective element is installed, the cutting edge between the side plane and the front plane therefore preferably defines the vertical direction. The front length is measured parallel to this vertical direction, with the front length preferably being significantly greater than the cross-sectional thickness of the front section. In this way, when installed, the front section projects downwards from the underside of the window frame, with the extension length in this direction being significantly greater than the thickness of the front section.

[0011] In one embodiment, the base section and the front section are constructed as a single piece. The single-piece design of the front section with the base section also ensures more cost-effective production of the protective element. For greater variability and variety, a two-part design of the protective element could alternatively allow different sized front sections to be attached to a base section, thus enabling various window or door systems to be equipped with protective elements according to the present invention.

[0012] In one embodiment, the base section has a cross-section with a wedge-shaped geometry, at least in some regions. The wedge-shaped geometry of the base section serves, on the one hand, to achieve improved strength of the protective element in that the base section has a greater cross-sectional thickness in the transition area to the front section than in the area distally facing away from the front section. In addition, a sloping underside of the base section resulting from the wedge-shaped geometry is better adapted to the geometry of a window sill or cornice covering that also extends at an angle. This enables the base section, with its sloping underside, to rest directly and over its entire surface on, for example, the end of a window sill. This covers any gaps through which driving rain could penetrate.On the other hand, in this case the protective element is arranged and fixed even more securely in the window or door system, as it is not only held in position on the underside of the frame by an adhesive connection, but is also supported on the window sill and / or the window sill end.

[0013] Preferably, a cross-sectional thickness of the base section, measured parallel to the front plane, is greater adjacent to the front section than at an end of the base section facing away from the front section. The wedge-shaped geometry of the base section is thus preferably oriented such that the thicker end of the wedge is located in the transition area between the base section and the front section.

[0014] Preferably, a top and bottom side of the base section are inclined relative to each other at a wedge angle, with the wedge angle being 2° to 10° and preferably approximately 4° to 6°. A wedge angle of 2° to 10° essentially corresponds to the usual inclination of a window sill or cornice covering, which allows the use and secure attachment of the protective element to a variety of known window or door systems.

[0015] In one embodiment, the front section has an edge section that projects beyond the base section on its upper side. The edge section ensures, in particular, better positioning of the retaining section on the base section. Furthermore, the edge section achieves better support of the protective element on the frame, which supports the adhesive fixation by the retaining section.

[0016] In one embodiment, the front section has a front break point, wherein the front break point is spaced from an upper edge of the front section by a front break distance, wherein the front break distance is 0.2 to 0.8 times and preferably 0.5 to 0.7 times a front extension of the front section measured parallel to the front plane. Alternatively or in addition to a modular design of the protective element in order to be able to equip a variety of different window or door systems, the front section can have at least one front break point at which the front section can be easily shortened. A front break point is therefore referred to as a predetermined breaking point on the front section. It has proven useful to space the front break point from the upper edge of the front section by a front break distance of 0.2-0.8 times.Particularly preferably, a plurality of front break points can be provided on the front section, which allows a greater variety of variants.

[0017] In one embodiment, the front section comprises at least two sections with different front extensions. In addition to or as an alternative to the design with a front break point, the front section can also comprise sections arranged side by side with different front extensions. This also allows for improved adaptation of the front section to specific window or door systems.

[0018] In one embodiment, the protective element has a plurality of predetermined breaking points at which the protective element can be shortened to a smaller extent. Similar to the design of the front section with a front breaking point, the entire protective element can have a plurality of predetermined breaking points at which, in particular, the extension of the protective element can be shortened parallel to the cutting edge between the front plane and the floor plane. The predetermined breaking points of the protective element thus preferably extend over both the floor section and the front section, such that a fitter can remove part of the floor section and an equal part of the front section when cutting the support element to length, thus shortening the protective element. The design of various predetermined breaking points on the protective element simplifies the installation and adaptation of the protective element to a specific window and / or door system.

[0019] Furthermore, the invention provides a window or door system comprising a frame and a protective element with the features described above, wherein the holding section of the protective element is fixed to the frame in such a way that an underside of the frame is partially covered by the protective element. In addition to covering the underside of the frame, the protective element is preferably also designed to cover the side of the frame with its side section in such a way that no water can penetrate this area either. The frame of the window sill system or door system is advantageously made of plastic, which allows a particularly strong adhesive connection. Particularly preferably, the front section of the protective element, together with the window sill, encloses a space between the wall flange of the window sill and the front section.

[0020] Further features and advantages of the present invention will become apparent from the following description with reference to the accompanying figures. It is understood that individual features of certain embodiments may also be applied to other embodiments.

[0021] They show: Fig. 1 - an embodiment of a protective element according to the present invention; Fig. 2 - an embodiment of a window or door system; Fig. 3 - a perspective view of an embodiment of a window or door system; Fig. 4 - an embodiment of a protective element; and Fig. 5 - a perspective view of an embodiment of a protective element.

[0022] The Fig. The perspective view of an embodiment of a protective element 1 shown in Figure 1 has a side section 2, a front section 3 and a base section 4. The side section 2 extends essentially parallel to a side plane S, the front section 3 essentially parallel to a front plane F and the base section 4 essentially parallel to a base plane B. The intersection lines between the three planes S, F, B preferably correspond to the main axes of the three-dimensional space, i.e. two horizontal main axes and one vertical main axis. The extension length of the side section 2 perpendicular to the base plane B is many times greater than its extension perpendicular to the front plane F. The side section 2 preferably has a maximum extension length of 40 mm to 80 mm and particularly preferably of 50 mm to 70 mm.In this embodiment, a holding section 5 is provided with a first holding part 51 and a second holding part 52, each of which has an adhesive surface 54 on each of the holding parts 51, 52. The adhesive surfaces 54 are designed for adhesive attachment to the frame 12 of a window or door system 10 (see ). Fig. 2). The front section 3 projects downwards from the base section 4 and thus covers the area below the base section 4. This covering by the front section 3 ensures improved rain protection, particularly in the area of ​​the lower edge of a frame 12 of a window or door system 10. Preferably and in the embodiment of Fig. 1, the side section 2, the front section 3 and the bottom section 4 are each designed as flat and substantially rectangular sections. In the embodiment of Fig. 1, the side section 2, the base section 4 and the front section 3 are designed as one piece with each other, wherein the holding section 5 is constructed in two parts and has a first holding part 51 and a second holding part 52 which are fixed independently of each other to the side section 2 and to the base section 4.

[0023] Fig. The embodiment of a window or door system 10 shown in Figure 2 has a frame 12, to the underside of which a protective element 1 is fixed. The base section 4 and the front section 3 of the protective element 1 can be seen. The window or door system 10 also has a window sill F and a window sill end 13. When the protective element 1 is installed, the base section 4 rests with its underside on the window sill end 13 and is thus held in a secure position between the window sill end 13 and the frame 12. The front section 3 extends from the frame 12 in the direction of the window sill F in such a way that a space between the wall flange of the window sill F (right, distal end of the window sill F) and the front section 3 is partially enclosed.In this way, the front section 3 of the protective element 1 protects the area of ​​the wall flange of the window sill F and in particular the gap provided in this area, which is also called the trade hole.

[0024] The Fig. The embodiment of a protective element 1 shown in Figure 3 is similar to that shown in Fig. 1. In addition to the embodiment shown in Fig. 1, however, predetermined breaking points 11 are provided on the protective element 1, at which the combination of base section 4 and front section 3 can particularly preferably be shortened. In the present example, two predetermined breaking points 11 are provided, although further predetermined breaking points 11 can preferably also be provided, not only in the region of the front section 3 and the base section 4, but also in the region of the side section 2. Additionally or alternatively, the front section 3 preferably has regions with different front extensions, i.e. different distal extensions perpendicular to the base plane B. Thus, the two sections of the front section 3 arranged further to the right in the figure are designed with a smaller extension than the region of the front section 3 arranged on the left and adjacent to the side section 2.

[0025] Fig. 4 shows a side or sectional view of a protective element 1, particularly showing the wedge-shaped geometry of the base section 4, in which an upper side 42 and a lower side 44 of the base section 4 enclose a wedge angle α with each other, which is preferably in the range of 2° - 10° and preferably approximately 4° - 6°. The lower side 44 of the base section 4, which is thus oriented obliquely to the floor plane B, is particularly well suited for being supported on a window sill end that is also obliquely positioned to the floor plane B or on another, likewise obliquely arranged geometry of a window sill. Furthermore, the front section 3 has a front break point 34, at which the front section 3 can be shortened. The distance of the front break point 34 from the upper edge of the front section 3 is referred to as the front break distance 36 and is preferably in a ratio of 0.6 to 0.8 to the front extension 38 of the front element 3.Furthermore, the front section 3 has an edge section 32 which projects beyond the upper side 42 of the base section 4 and thus provides a contact geometry for the fastening of the holding section 5 to the base section 4.

[0026] Fig.Finally, Figure 5 shows a further embodiment of a protective element 2, in which the side section 2 of the previous embodiment is not present, but instead only a region of the protective element extending parallel to the side plane is designed for positive engagement with the distal end of a window sill or window sill end. Advantageously and to increase mechanical stability, the protective element 1 has at least one reinforcing strut 6, which is fixed to the base section 4 and a front section 3. The reinforcing rib 6 thus prevents pivoting of the front section 3 relative to the base section 4, which could lead to breakage of the protective element 1.
