Description

[0001] Weather legs for plastic extrusion wing profiles

[0002] The present invention relates to a weatherboard for a window and / or door sash member, in particular made of an extruded profile, preferably made of plastic. Furthermore, the present invention relates to a window and / or door sash member with a weatherboard.

[0003] Basically, weatherboards are known and are attached to the lower structural edge of window and door sashes in such a way that they are arranged on the outside of the door and / or window sash and protrude from the door in order to fulfil the drip and dirt-repellent function, whereby the weatherboards have a receptacle for receiving a seal that cooperates with the substrate or the threshold.

[0004] There are already approaches in the prior art to utilize the space created between the underside of the door and / or window sash and the substructure to accommodate the weatherboard, thereby achieving smaller dimensions in the depth direction transverse to the longitudinal extension of the stile. For example, EP 3 130739 Bi discloses a plastic sash stile with the weatherboard attached to the underside of the stile facing the sill. This extends in the depth direction beyond the depth of the stile and thus continues to protrude into the surrounding area.

[0005] In addition, for example, in EP 0 579 950 Ai, a bearing profile that also functions as a weatherboard is attached to the underside of the beam. Attached to the weatherboard, in turn, is a sealing bracket equipped with a gasket to provide the sealing function against the substructure.

[0006] Several problems have been identified with the weatherboards used in the prior art. Firstly, it is always necessary to construct individual weatherboards depending on whether the sash opens inward or outward. Furthermore, the weatherboards known in the prior art are complex, particularly consisting of separate components, and / or protrude beyond the depth of the spars into the surrounding area.

[0007] An object of the present invention is to overcome the disadvantages of the prior art, in particular to provide a weatherboard that can be used flexibly and / or is easy to manufacture.

[0008] The problem is solved by the features of the independent claims.

[0009] The present invention relates to a weatherboard for a window and / or door sash member. The weatherboard basically serves to provide a drip-drying and / or dirt-repelling function to protect the lower structural edge of the window and / or door sash member from dirt and liquids, and further to support seals and / or other functional elements, such as brush or broom elements for sweeping away or scraping off dirt, which cooperate with the substrate, such as a threshold, thus creating a sealing function. The window and / or door sash member can be made from an extruded profile, preferably from plastic, such as PVC. The extruded profile can define an extrusion direction in which it has a constant cross-section.

[0010] The weatherboard according to the invention comprises three receptacles open to the environment, each of which can optionally be equipped with a seal or other functional element, and which are arranged such that the weatherboard can be used optionally for an inward-opening or an outward-opening window and / or door sash. The receptacles can generally be designed to each accommodate a seal or a functional element and hold it on the weatherboard. Because the weatherboard is designed such that it can be used for both an inward-opening and an outward-opening window and / or door sash, a significantly wider range of window and / or door sashes can be covered with just a single weatherboard.The arrangement of the receptacles on the weatherstrip can be such that there is at least one receptacle that is occupied by a seal exclusively in the case of an inward-opening or exclusively in the case of an outward-opening window and / or door sash. For example, the receptacles are arranged on an underside that points towards the window and / or door sash stile when the weatherstrip is installed and that faces the substructure, such as the sill. In this way, it is possible to occupy the receptacles with different elements, depending on the type and design of the window and / or door sash, whereby the elements are arranged in a mirror-inverted manner for inward-opening and outward-opening window and / or door sashes.

[0011] According to an exemplary embodiment of the weatherboard according to the invention, the receptacles are each shaped to positively accommodate, in particular hold, a seal. The positive engagement of the seal in the receptacle ensures quick, reliable, and / or removable installation of the seals.

[0012] In a further exemplary embodiment of the present invention, the receptacles are each shaped to form at least one undercut, in particular two undercuts, which can be engaged behind by a mounting base of the respective seal. For example, the receptacles define an insertion direction in the direction of the open cross-section, via which the respective seal is to be inserted or mounted in the receptacle. The at least one undercut is to be understood with reference to the insertion direction, such that it blocks removal of the seal from the receptacle opposite to the insertion direction. In a further exemplary embodiment of the weather strip according to the invention, the receptacles have an elongated, flat cross-section and an insertion opening on one of the long sides for the seal. In particular, the cross-section has a greater width than height and / or is symmetrical with respect to a central axis.

[0013] Furthermore, in the weatherboard according to the invention, two of the three receptacles can be arranged directly next to each other and separated from each other by a common web of the weatherboard. In other words, the separating web can at least partially delimit two receptacles arranged next to each other. This allows for the creation of a particularly compact weatherboard.

[0014] According to an exemplary development of the weatherboard according to the invention, the two receptacles are arranged on one edge of the weatherboard, and a third receptacle is arranged on an opposite edge. It has been found that this arrangement of the receptacles on the weatherboard can reliably protect both the inward-opening and the outward-opening window and / or door sash from dirt and / or moisture if the corresponding receptacles are covered with a seal.

[0015] In a further exemplary embodiment of the present invention, the weatherboard is made from a single piece, particularly from metal, such as aluminum, or plastic, such as PVC. This makes the weatherboard particularly suitable for mass production and can be manufactured cost-effectively and with few manufacturing steps, in particular without the need for additional components and / or fastening devices.

[0016] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a window and / or door leaf spar is provided with a cross-section that is substantially constant in a longitudinal direction, in particular an extrusion direction, in particular made of an extruded profile, preferably made of plastic. Window and / or door leaf spars are understood to be frame parts of the window and / or door leaves. For example, the window and / or door leaf spar according to the invention is a horizontal spar, in particular the horizontal spar facing the ground.

[0017] The window and / or door leaf pillar according to the invention comprises an underside facing a surface, such as a threshold. Any liquids that collect and drain inside the profile of the pillar or run off its exterior side facing the environment can drip off the underside.

[0018] The window and / or door leaf sash further comprises an outer drip edge arranged on the underside, extending longitudinally and facing the environment, and an inner drip edge arranged on the underside, extending longitudinally and arranged transversely to the longitudinal direction in a depth direction at a distance from the outer drip edge. It has been found that drainage can be particularly effective via two spaced-apart drip edges. The outer drip edge primarily serves to drain liquids present on the outside of the sash facing the environment, while the inner drip edge primarily serves to drain liquids accumulating within the sash profile.

[0019] The window and / or door sash member according to the invention further comprises a weatherboard, particularly designed according to the invention, which is preferably made from a single piece and / or is attached to the underside in such a way that a contact web of the weatherboard rests on a side of the inner drip edge facing away from the outer drip edge. This prevents capillary action on the weatherboard of the liquid to be drained off via the inner drip edge, thus achieving reliable drainage of the window and / or door sash member. By draining or draining any liquids on the side of the drip edge facing the outer drip edge or the surroundings, the arrangement of the contact web on the side of the drip edge opposite the outer side prevents capillary action, which would otherwise counteract reliable drainage.

[0020] According to an exemplary development of the window and / or door leaf spar according to the invention, the weatherboard has a further support web, oriented in particular parallel to the support web, which rests against the underside and is clamped to the underside together with the other support web to secure the weatherboard. For example, at least one of the support webs can deform, in particular elastically, thereby building up, for example, a particularly elastic deformation restoring force that effects a fastening / holding force.

[0021] According to a further exemplary embodiment of the window and / or door sash member according to the invention, the weatherboard has a support leg, particularly adjacent to the further support web, for a particularly flat contact with the underside. The particularly flat contact of the weatherboard with the underside ensures that the weatherboard remains in the desired position, so that the seals accommodated by the weatherboard are optimally aligned to ensure the desired drip-off and / or repellency function.

[0022] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a window and / or door leaf spar is provided with a cross-section that is substantially constant in a longitudinal direction, in particular an extrusion direction, in particular made of an extruded profile, preferably made of plastic. Window and / or door leaf spars are understood to be frame parts of the window and / or door leaves. For example, the window and / or door leaf spar according to the invention is a horizontal spar, in particular the horizontal spar facing the ground.

[0023] The window and / or door leaf pillar according to the invention comprises an underside facing a surface, such as a threshold. Any liquids that collect and drain inside the profile of the pillar or run off its exterior side facing the environment can drip off the underside.

[0024] The window and / or door leaf sash further comprises an outer drip edge arranged on the underside, extending longitudinally and facing the environment, and an inner drip edge arranged on the underside, extending longitudinally and arranged transversely to the longitudinal direction in a depth direction at a distance from the outer drip edge. It has been found that drainage can be particularly effective via two spaced-apart drip edges. The outer drip edge primarily serves to drain liquids present on the outside of the sash facing the environment, while the inner drip edge primarily serves to drain liquids accumulating within the sash profile.

[0025] The window and / or door sash member according to the invention further comprises a weatherboard, particularly designed according to the invention, which is preferably made from a single piece and / or is attached to the underside and / or shaped such that there is a minimum distance in the direction of gravity of at least 5 mm between the outer drip edge and a drainage leg of the weatherboard facing said edge. This minimum distance ensures that liquid can reliably drip off the drip edge, thus guaranteeing effective drainage, particularly since capillary action is excluded. While maintaining the minimum distance is counterproductive to the fundamental general efforts of window and / or door sash manufacturers to keep the necessary vertical height of such systems as low as possible, it is accepted in favor of significantly improved drainage.The drainage leg can be installed at an angle in the range of 15. 0 to 6o°, especially in the range from 20° to 45 0 , be oriented or inclined with respect to a depth direction and / or relative to the underside of the profile.

[0026] According to an exemplary embodiment of the window and / or door leaf sash according to the invention, the drainage leg is dimensioned such that water can drip from both the outer drip edge and the inner drip edge, in particular from a side of the inner drip edge facing the outer drip edge, onto the drainage leg, particularly in the direction of gravity. Due to the dimensions of the drainage leg and / or the coordinated arrangement of the drip edges and the drainage leg, the drainage leg can drain liquids released from both the inner drip edge and the outer drip edge.

[0027] According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a window and / or door sash member is provided. The window and / or door sash member comprises a profile, in particular an extrusion profile, preferably made of plastic, such as PVC, with a cross-section that is essentially constant in a longitudinal direction, in particular an extrusion direction, and a profile outer side that faces the surroundings and extends transversely, in particular perpendicularly, to the longitudinal direction. Window and / or door sash members are understood to be frame parts of the window and / or door leaves. For example, the window and / or door sash member according to the invention is a horizontal sash member, in particular the horizontal sash facing the ground.

[0028] The window and / or door leaf pillar according to the invention comprises an underside facing a surface, such as a threshold. Any liquids that collect and drain inside the profile of the pillar or run off its exterior side facing the environment can drip off the underside.

[0029] The window and / or door leaf sash further comprises an outer drip edge arranged on the underside, extending longitudinally and facing the environment, and an inner drip edge arranged on the underside, extending longitudinally and arranged transversely to the longitudinal direction in a depth direction at a distance from the outer drip edge. It has been found that drainage can be particularly effective via two spaced-apart drip edges. The outer drip edge primarily serves to drain liquids present on the outside of the sash facing the environment, while the inner drip edge primarily serves to drain liquids accumulating within the sash profile.

[0030] The window and / or door sash member according to the invention further comprises a weatherboard, particularly designed according to the invention, which is preferably made from a single piece and / or is attached to the underside and shaped in such a way that it does not protrude beyond an outer side of the profile transversely to the longitudinal direction in a depth direction of the window and / or door sash member, and has at least two receptacles for each receiving a seal to be brought into sealing contact with the substrate, such as the threshold. Because the weatherboard does not protrude beyond the depth of the profile, a special aesthetic is created, and a significantly more space-saving window and / or door sash member can be produced. Furthermore, any damage to the weatherboard and / or the window and / or door sash member can be avoided, which in the prior art resulted in people or objects hitting the weatherboard.

[0031] In another exemplary embodiment of the window and / or door sash member according to the invention, the weatherboard is flush with the underside, in particular with an outer drip edge facing the outside. This flush arrangement allows for the above-described advantage of space-saving accommodation of the weatherboard, while also achieving the most effective drainage possible, as far away as possible from the interface between the underside of the profile and the sill.

[0032] In a further exemplary embodiment of the window and / or door sash member, the weatherboard extends in the depth direction over at least 25%, in particular at least 30%, at least 35%, or at least 40%, of a total extension of the underside in the depth direction. A dimension in the height direction, in particular transverse to the depth and longitudinal direction, can be in the range of 10%-50% of the depth extension of the weatherboard. For example, a casement window sash made of a sash member according to the invention, whose weatherboard carries two seals, such as a brush seal or a lip seal, has a very low driving rain resistance according to EN 1027:2016-03. The spray angle is 24 0Five spray nozzles are used, delivering a water flow rate of 600 Pa / h, with three pressure pulses. The wing spar according to the invention is characterized by particularly good leak tightness. No water penetrates up to and including 600 Pa.

[0033] Preferred embodiments are given in the subclaims.

[0034] In the following, further properties, features and advantages of the invention will become clear by describing preferred embodiments of the invention with reference to the accompanying exemplary drawings, in which:

[0035] Figure 1 is a cross-sectional view of an exemplary embodiment of a window and / or door leaf spar according to the invention with a weatherboard according to the invention;

[0036] Figure 2 shows the window and / or door sash member according to Figure 1 in combination with a threshold;

[0037] Figure 3 shows a further example of a window and / or door leaf spar according to the invention;

[0038] Figure 4 shows the window and / or door wing post according to Figure 3 in combination with a threshold; and

[0039] Figures 5-10 show further exemplary embodiments of window and / or door leaf spars according to the invention with further exemplary embodiments of weatherboards according to the invention. In the following description of exemplary embodiments of the present invention, a weatherboard according to the invention is generally designated by reference numeral 1, and a window and / or door leaf spar according to the invention, which is also referred to as a "spar" for the sake of simplicity, is generally designated by reference numeral 3.

[0040] In the exemplary embodiments according to all figures, the stile 3 and the weatherboard 1 are shown in a cross-sectional view. The stile 3 is designed, for example, as a plastic, in particular PVC, extrusion profile and is defined by an extrusion direction E, in which the stile 3 has a substantially constant profile cross-section. The weatherboard 1 is, for example, an aluminum part which also has a substantially constant cross-section in the extrusion direction E and extends over substantially the entire extent of the stile 3 in the extrusion direction E. In the exemplary embodiments, the stile 3 is in each case a lower horizontal stile, i.e. one facing a base or a threshold 5, which delimits the window and / or door leaf downwards in the vertical direction.

[0041] The beam 3 comprises a profile designed as an extrusion profile 7 with a cross-section that is essentially constant in the extrusion direction E, which has an outer profile side 9 facing the environment and an underside 11 facing the substrate, such as the sill 5. The extrusion profile 7 is designed as a hollow chamber profile and can, in principle, have any internal profile structure. On an upper side opposite the underside 11, the extrusion profile 7 comprises a glazing rebate 15 for receiving glazing. On the underside 11, the extrusion profile 7 has a fitting groove 17 for receiving fitting elements and at least two drip edges 19, 21, of which an outer drip edge 19 is arranged at the level of the profile outer side 9 and an inner drip edge 21 is arranged at a distance therefrom in a depth direction T that is oriented perpendicular to the height direction H and to the extrusion direction E.Figure 4 schematically shows the drainage of any liquid accumulating inside the profile via drainage openings present in the profile to the inner drip edge 21, further to the weather leg 1, from there to the sill 5 and finally into the outside environment A, indicated by the reference symbol W.

[0042] The weatherboard 1 is dimensioned and / or attached to the underside 11 of the stile 3 such that the weatherboard does not protrude beyond the profile outer side 9 in the depth direction, but in particular is flush with it. As can be seen from a combination of Figures 1 and 2, the weatherboard 1 is further dimensioned and / or arranged in relation to the profile 7 such that a distance a in the height direction H, namely in the direction of gravity, of at least 5 mm exists, so that reliable drainage is ensured and the risk of capillary action on the weatherboard 1 is reduced. Furthermore, a distance b of at least 5 mm must be maintained between an underside 23 of the weatherboard 1 facing the sill 5 and the sill 5 in order to ensure reliable drainage here too, without capillary action occurring.

[0043] The weatherboard 1 has a flat, elongated structure and has on its underside 23 three receptacles 25, 27 and 29 which are open towards the environment and which, depending on the application for an inward-opening or an outward-opening window and / or door leaf, can be optionally provided with a seal 31, 33 each. From a comparison of the embodiment according to Figures 1 and 2, which is a spar 3 of an outward-opening window and / or door leaf, with the embodiment according to Figures 3 and 4, which is a spar 3 of an inward-opening window and / or door leaf, it can be seen that, depending on the type of window and / or door leaf, a pair of seals 31, 33, which can also be different from one another, wherein a two-lip seal 31 and a bristle seal 33 can be used, are always arranged in different receptacles 25-29, while one of the receptacles 25-27 remains unoccupied.From the overview of Figures 1-4 it is evident that basically two types of window and / or door leaves can be used with one and the same weatherboard 11 without the need for a redesign of the weatherboard 1, whereby simply a different assignment of the sealing receptacles 25-29 is sufficient.

[0044] The weatherboard 1 is fastened to the profile underside 11 in such a way that the weatherboard rests flat against the profile underside 11 with an elongated support leg 35 and is held, for example, in a clamped manner. The clamping can be achieved, for example, via two contact webs 37, 39 arranged at a distance from one another in the depth direction T, wherein an outer contact web 39 rests against an inner side of the inner drip edge 21 facing away from the outer drip edge 19 and a further contact web 37 rests against a profile web of the profile 7 in a contact contact, in particular in a clamped manner, preferably with elastic deformation to build up a particularly elastic deformation restoring force, which provides the holding force.Because the contact web 39 rests on the inside of the inner drip edge 21, liquid can reliably drip off the drip edge 21, as indicated in Figure 2 by reference symbol W, at a distance from the contact web 39 onto a drainage leg 41 inclined obliquely with respect to the depth direction T, without the risk of capillary action on the weather leg 1. The drainage leg 41 is at an angle in the range of 15. 0 to 6o°, especially in the range from 20° to 45 0 , oriented or inclined with respect to the depth direction T.

[0045] The seals 31, 33 have a mounting base 47, which can be implemented as a thin web and is designed to engage behind an undercut 45 formed by the seal receptacle 25-29, such that the seals 31, 33 are held in a form-fitting manner in the respective seal receptacle 25-29. It can be provided that the seals 31, 33 can only be mounted in the seal receptacles 25-29 in an assembly direction oriented parallel to the extrusion direction E. The seals 31, 33 further have a sealing element 49 protruding from the mounting base, which is responsible for the sealing function, is in particular elastically deformable and protrudes from the mounting base 47 out of the seal receptacle 25-29 in such a way that the seals 31, 33 can come into sealing contact with the substrate, such as the sleeper 5, by means of the sealing element 49. As can be seen from the overview of Figures 1-4, in particular Figures 2 and

[0046] 4, which are shown in combination with the threshold 5, in the outward-opening window and / or door leaf according to Figure 2, the two outer sealing receptacles 27 and 29 are each occupied by a seal, while the inner seal 25 is free. In the inward-opening window and / or door leaf according to Figure 4, the outer sealing receptacle 29 is unoccupied and the two other sealing receptacles, which are arranged directly next to one another and separated from one another by a common web 43, are each occupied by a seal 31, 33. The weatherboard 1 according to the invention can therefore be used for both an inward-opening (Figures 3 and 4) and an outward-opening (Figures 1 and 2) window and / or door leaf without any structural changes. The different opening movements of the window and / or door leaf can be seen from Figures 2 and 4 respectively.4, wherein the outward-opening window and / or door leaf according to Figure 2 opens to the left in the illustration in the direction of the external environment indicated by the reference symbol A, which is located outside a building, while the inward-opening window and / or door leaf according to Figure 4 opens to the right in the illustration in the direction of the internal environment indicated by the reference symbol I, which is located inside a building.

[0047] Figures 5-10 show further exemplary embodiments of weatherboards 1 according to the invention in combination with window and / or door sash members 3 according to the invention, which are basically constructed according to the same principle and achieve the drainage and dirt-repelling functions. In the figures

[0048] Figures 5, 7, 9, and 10 show exemplary designs of weatherboards with only two receptacles for seals, which are used, for example, when the extension of the stile 3 in the depth direction of adjacent fitting groove 17 is limited or reduced, while nevertheless ensuring that the weatherboard can be used for both an inward-opening and an outward-opening window and / or door leaf. As can be seen in Figure 9, the weatherboard 1 can alternatively or additionally be screwed to the stile by means of a screw 51. The features disclosed in the above description, the figures, and the claims can be important both individually and in any combination for the realization of the invention in the various embodiments.
