Description

The present invention relates to a sealing element for sealing a casement with respect to a guide rail of a window frame. In particular, the invention relates to a sealing element for sealing sliding windows and sliding doors. Moreover, the present invention relates to a sliding window or a sliding door with such a sealing element.

In particular sliding windows and sliding doors consist of a sash which is slidably mounted on a guide rail of a window frame. For this purpose, the wing frame on its top and bottom longitudinal grooves, which are adapted to receive the guide rail of the frame and enclose. In order to attach the casement even after the assembly of the frame on the guide rails, it is known from the prior art to design at least one of the longitudinal grooves of the casement deeper than would be necessary for receiving the guide rail. Consequently, there is a clearance between the guide rail and the profile of the sash, which leads to the formation of unwanted heat bridges between the outside and the inside of the window or the door.

For the reasons mentioned above, it is known from the prior art, at least the end portion of the longitudinal grooves of the sash with respect to the guide rail of the frame, after insertion of the sash in the Frame, seal. For this purpose, it is known, for example, foam-like insulating material to provide at least in the edge region of the longitudinal groove, which fills the space between the sash and the guide rail. Alternatively or additionally, covering elements adapted precisely to the groove area are known, which serve to cover the end region of the longitudinal groove and thus to prevent a direct passage of air.

In the sealing elements known from the prior art, it is considered problematic that they can be attached only with relatively great effort to the longitudinal groove of the casement. Also, the conventional sealing elements are often inadequately connected to the casement, so that they solve too easily from the casement. Finally, often only an insufficient sealing effect is given because the conventional sealing elements are very difficult to align with respect to the longitudinal groove of the sash.

Based on the above-mentioned problem, the present invention has the object to provide a sealing element for sliding windows and sliding doors, which can be quickly and easily connected to the longitudinal groove of a sash and at the same time achieves a particularly high sealing effect. In addition, the novel sealing element, even under heavy load, be firmly connected to the sash.

The above object is achieved by the sealing element according to independent claim 1.

Accordingly, the sealing element according to the invention for sealing a casement with respect to a guide rail of a window frame on an anchoring area and a cover, which are integrally formed with each other. The anchoring area is designed, in particular, to engage in an interior of the casement and to fasten the sealing element to the casement. In contrast, the covering area is designed to cover the Lägnsnut the sash substantially completely. For this purpose, the cover is attached to an outside of the sash.

The advantages of the sealing element according to the invention is obvious: So it is possible by the integral formation of the sealing element, time in the Save installation on the casement, since only one step is necessary for fixing the covering area and the anchoring area. Of course, this simultaneously simplifies the entire assembly process considerably. By connecting the covering area with an anchoring area for the interior of the casement, the sealing element according to the invention can be frictionally connected to the casement, whereby an independent release of the sealing element from the casement is effectively prevented. Finally, the sealing element according to the invention is in the installed state in close contact with a side wall of the sash, whereby a particularly high sealing effect is achieved.

Advantageous developments of the sealing element according to the invention can be found in the dependent claims.

Thus, according to a first realization of the sealing element, provision is made for the anchoring area to have flexible pressing elements which can be attached to an inner wall of the longitudinal groove such that a frictional connection is created between the longitudinal groove and the sealing element. For this purpose, the flexible pressing elements may in particular have a substantially vertical orientation so that they serve as guide elements when the sealing element is pushed onto the casement frame. Due to the flexible design of the pressing is also achieved that the sealing element according to the invention, even if not exactly met tolerances of the longitudinal groove, quickly and easily fastened to the casement.

According to a further embodiment of the sealing element according to the invention, it is provided that the anchoring area further comprises clamping profiles which are aligned perpendicular to the flexible pressing elements and parallel to the covering area. The clamping profiles are designed to clamp a first wall portion of the sash between the clamping profiles and the cover. In other words, an intermediate space is created by the clamping profiles between the covering area and the clamping profiles, which serves to introduce a first wall area of the casement. Accordingly, the clamping profiles are spaced further from the cover profile in such a way that the intermediate space created thereby corresponds exactly to the width of said wall region. Of course, this is the fastening effect the sealing element according to the invention on the casement even further improved.

After a further implementation of the sealing element according to the invention, it is provided that the anchoring region has flexible sealing elements, which are aligned parallel to the pressing elements of the anchoring region and adapted to be sealingly connected to the guide rail of the window frame. Due to the flexible sealing elements, the sealing element according to the invention when pushed onto the casement is at the same time connected to the guide rail of the window frame. The flexible design of the sealing elements is further ensured that they are in close contact with the guide rail and thus effectively prevent any air exchange between the guide rail and the interior of the sash.

According to a further aspect, the covering region of the sealing element according to the invention has a projection which is arranged on a side of the covering region facing the anchoring region. The projection is in particular adapted to engage in a designated opening of the sash. For this purpose, the projection may be formed, for example, circular or semicircular, so that it can engage in an additional bore on the side wall of the sash. As soon as the projection engages in the corresponding opening, a positive connection between the casement and the sealing element is achieved, whereby the sealing element is more reliably connected to the casement. In detail, the sealing element according to the invention according to this embodiment is firmly connected to the casement so that the sealing element can be solved only by the use of tools from the casement.

According to a further embodiment, it is provided that the anchoring region of the sealing element additionally has a substantially horizontally extending bottom region, which is designed to cover an underside of the casement. The substantially horizontally extending bottom area once again improves the sealing effect between the casement and the guide rail of the window frame. In addition, the bottom portion also forms a stop, to which the sealing element can be pushed onto the casement.

According to a further embodiment, the anchoring region of the sealing element, in addition to attachment to the casement, be adapted to fasten a foam element above the guide rail, in the interior of the window sash. It is conceivable, for example, that the above-mentioned pressing elements are adapted to fix an existing of a foamed material insulating layer in the interior of the sash. Of course, this further enhances the sealing effect of the sealing element according to the invention.

The sealing element is preferably formed from a plastic material. Accordingly, it is ensured that arise through the sealing element no thermal bridges on the sash. Furthermore, it is preferable to form the sealing element as an injection-molded part, whereby the production can be simplified and costs can be saved.

As already indicated above, the present invention also relates to a sliding window or a sliding door which has at least one sealing element according to the invention. The sliding window according to the invention comprises a frame and at least one wing frame, wherein the wing frame is slidably mounted on a guide rail of the frame via a longitudinal groove. The casement has at least one sealing element according to the invention, which is releasably attached to one end of the longitudinal groove. The sliding window according to the invention or the sliding door according to the invention has a particularly high sealing effect, since the longitudinal groove of the sash is reliably sealed.

The sealing element according to the invention is explained in more detail below with reference to the embodiment shown in FIGS.

The picture according to Fig. 1 shows a partial perspective view of a known from the prior art sliding window. In detail, the illustration shows a corner region of a window frame 2. The frame 2 of the sliding window 1 has, in the example shown here, two horizontally extending guide rails 21 and 22, respectively. At least one casement 3, for opening and closing the sliding window 1, is displaceably mounted on each of the guide rails 21, 22. The wing frame 3 shown here has in particular two horizontal and two vertical frame sections, of which only the right vertical frame section 32 and the lower horizontal frame section 31 are shown. The four frame sections of the sash frame 3 enclose an insulating glass pane 33, which is shown in the embodiment shown here as a double glass pane.

To guide the casement 3 on the guide rail 21, a lower longitudinal groove is provided in the casement 3, which is designed to partially enclose the guide rail 21. In the illustration according to Fig. 1 In particular, only the end portion 321 of the longitudinal groove, which is part of the horizontal frame portion 32, is shown. As already mentioned above, the longitudinal groove of the casement 3 is formed larger than would be necessary to embrace the guide rail 21 in order to lift the casement 3 during assembly in the guide rail 21 and 22 of the frame 2. As can be seen at the end region 321 of the longitudinal groove, however, this creates a free space between the guide rail 21 and the upper end of the longitudinal groove indicated here. From the prior art, it is known to seal this space, for example by insulating foam. However, as already indicated, this has the disadvantage that the introduction is associated with a relatively large effort and only an insufficient sealing effect is achieved.

In order to improve the sealing effect in a simple manner, it is proposed with the present invention, a sealing member 40 at the end portion 321 of the longitudinal groove of the sash 3 to install, as for example from Fig. 4b is apparent. The exact structure of the sealing element 40 according to the invention is in particular from the Figures 2a to 3d seen. The show FIGS. 2a and 2b perspective views of the sealing element according to the invention, while the FIGS. 3a to 3d represent two-dimensional views of the seal member 40.

Like that FIGS. 2a and 3b 2, the sealing element generally has an anchoring area 60, which is attached to a covering area 50 of the sealing element 40. The anchoring area 60 is designed to engage in an interior of the sash 3. On the other hand, the cover portion 50 serves to be attached to an outer side of the sash frame and to substantially completely cover the end portion 321 of the longitudinal groove of the sash frame 3. The sealing element 40 is in particular formed in one piece, ie the anchoring area 60 is formed integrally with the covering area 50. Accordingly, it is advantageous to produce the sealing element 40 as an injection molded part. The anchoring area 60 serves to anchor the sealing element within the sash.

As below in terms of the FIGS. 4 to 6 will be explained, the anchoring portion 60 is adapted to engage in the interior of the vertical frame portion 32. For example, can be from the Fig. 2b recognize that the anchoring area 60 for this purpose has two pressing elements 62, which are formed on an inner wall of the end area (321, FIG. Fig. 1 ) of the longitudinal groove to be attached. Between the two pressing elements 62 extends a passage opening 69 which is dimensioned for the guide rail (21, 22, Fig. 1 ). In this connection, it should also be mentioned that the anchoring area 30, in addition to the pressing elements 62, has sealing elements 63, which are aligned parallel to the pressing elements and extend away from the pressing elements 62. The sealing elements 63 are designed to be flexible in order to seal with the guide rail (21, 22, Fig. 1 ) of the frame 2 to be connected. In the FIGS. 2b . 3a and 3d is indicated that the inner surfaces of the flexible sealing members 63 have tapered surfaces, whereby a protruding contact edge 631 is formed. The contact edge 631 serves, in particular, for the respective guide rail 21 or 22 of the window frame 2 (FIG. Fig. 1 ) as soon as it is inserted into the through hole 69.

Also is off Fig. 2b it can be seen that clamping profiles 61 extend perpendicular to the outside, ie parallel to the covering region 50, on each of the pressing elements 62. As in the FIGS. 3b and 3c 2, the clamping profiles 61, together with the covering area 50, form two intermediate spaces 611, which are designed to form a front side wall 323 (FIG. FIGS. 4a, 4b ) of the sash 3 record. The cover area 50 facing surface of the clamping profile 61 may in particular be slightly beveled, so that the intermediate region 611 is slightly inclined relative to the vertical. In addition to this, the covering region 50 may have on its inner side a wedge-shaped region 64 which has substantially the same bevel relative to the vertical as the clamping profiles 61. The wedge-shaped region 64 thereby widens in the direction of the bottom region 65. As will be explained in more detail later, the oblique formation of the intermediate region 611 reinforces the clip action of the sealing element 40 according to the invention. By a projection 66, which is located on the inside of the cover 50, the sealing element 40 according to the invention, as in connection with the FIGS. 4a and 4b will be explained in more detail, are positively connected to the vertical frame portion 32 of the sash 3.

Finally, it should be noted that an optional through-bore 67 can be provided on the cover region 50, which in addition to the elements of the anchoring region 60 already described can serve to secure the sealing element 40 to the sash frame 3 by means of a fastening screw. At the lower end portions of the pressing members 62 and the flexible sealing members 63, a substantially horizontally extending bottom portion 65 follows, which is adapted to cover the underside of the sash frame 3, as for example from Fig. 4b is apparent.

The FIGS. 4a and 4b For example, a procedure for installing the sealing element 40 according to the invention can be taken. First, the sealing member 40 according to the invention is applied to the lower portion of the side wall 323 of the vertical frame portion 32, so that the two flexible pressing members 62 are aligned with the end portion 321 of the longitudinal groove. In a second step, which in Fig. 4b is indicated, the sealing member 40 is pushed vertically upwards in the inner region of the vertical frame portion 32 and thus covers the end portion 321 of the longitudinal groove of the sash 3. In this context, it should be noted that the side wall 323 for receiving the projection 66 has a circular opening 322nd can have. The opening 322 can be either already provided during the manufacture of the sash 3 or introduced during assembly of the sealing member 40 with a drill in the side wall 323.

The insertion of the sealing element 40 into the interior of the vertical frame portion 32 is in the FIGS. 5a to 5c shown in more detail. For this purpose is in the FIGS. 5a and 5b a cross section through the center of the vertical frame portion 32 is shown. For reasons of clarity, a representation of the horizontal frame section 31 (FIG. Fig. 4a ), it being understood, however, that the longitudinal groove of the horizontal frame portion 31 is of course aligned with the end portion 321 shown here. In Fig. 5a is the in Fig. 4a shown installation state of the sealing element 40 in section. As can be seen, in this state, the cover portion 50 abuts against the side wall 323 of the vertical frame portion 32, the flexible pressing members 62 being aligned with the opening at the end portion 321 of the longitudinal groove. As shown in FIG Fig. 4b , the sealing element 40 is now in the direction of in Fig. 5a shown arrow inserted into the interior of the vertical frame portion 32.

This condition is in the Fig. 5b shown. It should first be noted that in Fig. 5b only the vertical frame portion 32 is shown in section, whereas the sealing member 40 is present in a non-cut side view. In the state according to Fig. 5b the sealing element 40 is pushed so far into the interior of the vertical frame portion 32 that the substantially horizontally extending bottom portions 65 abut the underside of the sash. At the same time, the projection 66 of the sealing element 40 snaps into the opening 322, whereby a positive connection of the sealing element 40 with the vertical frame section 32 of the sash frame 3 is achieved. The determination of the projection 66 in the opening 322 is made by pinching the side wall 323 within the gap 611, as with respect to the Fig. 5c will be explained in more detail.

In Fig. 5c is a laterally offset cross-section, which is located adjacent to the opening of the end portion 321 shown. Thus, from the Fig. 5c it can be seen how the side wall 323 of the vertical frame portion 32 is clamped in the space 611 of the sealing member 40. In particular, the front side wall 323 of the vertical frame section 32 is thereby clamped between the cover region 50 and the clamping profile 61 running parallel thereto. Since the intermediate space 611, as already indicated above, is formed in particular obliquely to the cover area 50, arises during insertion of the Side wall 323 in the intermediate region 611 a torque which braces the projection 66 in the direction of the opening 322. In other words, by the oblique formation of the intermediate portion 611, a pressing action of the cover portion 50 to the side wall 323 of the vertical frame portion 32 is effected.

In Fig. 6 Once again shown how the sealing element 40 of the invention can be attached to the sash 3 of a sliding window. For this purpose, the sealing element 40 is placed in the open state of the sliding window on the respective guide rail 21 and displaced in the direction of the end portion 321 of the longitudinal groove until the position shown in the illustration above right, which the state of Fig. 5a corresponds, is achieved. Once the sealing member 40 is aligned with the side wall 323 of the vertical frame portion 32, it is lifted with a pointed object (such as a screwdriver 70) and thus secured to the side wall 323, ie, in the interior of the vertical frame portion 32 (see FIG FIGS. 5b and 5c ). In the in Fig. 6 The upper left illustrated state, the sealing element is so firmly connected to the sash 3 that this can be solved only with the aid of a pointed object, such as the screwdriver 70, the sash 3. Thus, an undesired release of the sealing element 4 is excluded from the sash 3.
