Description

The invention relates to an anti-lift safety device for sliding windows and sliding doors comprising at least one leaf frame which can be guided via at least one longitudinal groove in a guide rail of a frame. The invention further relates to a method for mounting an anti-lift security according to the invention on a sliding window or on a sliding door. In general, the sliding windows and the sliding doors consist of a leaf frame which is slidably mounted on a guide rail of a frame. For this purpose, the leaf frame comprises on its upper face and on its underside longitudinal grooves which are made to receive and enclose the guide rails of the frame. To be able to plug the leaf frame onto the guide rail also after the assembly of the frame giving, it is known from the state of the art to design at least one of the longitudinal grooves of the leaf frame deeper than it would be required to house the guide rail. As a result, there is a free space between the guide rail and the leaf frame profile, which can be used to lift the leaf frame out of the frame. This circumstance often leads to break-ins in which raising the door frame allows access to the interior of a building.

Based on the problem cited above, the object of the present invention is to provide an anti-lift safety that can be quickly and easily reported on sliding windows or sliding doors known and that effectively prevents a rising leaf frame out of the giving frame.

This object is achieved in accordance with the invention by virtue of the fact that the anti-lift security comprises the following elements: - a covering zone for covering an end region of said at least one longitudinal groove of a leaf frame; and a fixing zone for releasably securing the anti-lift security on a vertical frame portion of a leaf frame.

The anti-lift security according to the invention has a plurality of advantages. Thus, the overlapping zone of the anti-lift safety device according to the invention can be used to limit the depth of the longitudinal grooves in a simple way at their edge regions, whereby the free space mentioned above is covered. . Therefore, thanks to the overlapping zone of the anti-lift security according to the invention, one can quickly and simply minimize the clearance between said at least one leaf frame and the frame. In addition, the anti-lift security according to the invention can be fixed in a particularly simple manner on a leaf frame of a sliding window or a sliding door. For this purpose, it is possible to use the fixing zone which is made in particular to be attached to a vertical frame part of the leaf frame. As will be explained in more detail below, the fixing zone can be made for this purpose so as to slide along the vertical frame part, whereby the position of the anti-lift safety on the leaf frame of the window or sliding door can be continuously adjusted.

Advantageous developments of the anti-lift safety of the invention are apparent from the remainder of this description. Thus, in a first embodiment of the anti-lift security according to the invention, it is provided that the overlap zone and the fastening zone are made in one piece. Thanks to the realization of a single piece of the anti-lift security, it is achieved that it can be fixed quickly and simply on the leaf frame of the sliding window of the sliding door. For this purpose, it is not necessary to fix a plurality of complicated components on the leaf frame during several operations. On the contrary, the anti-lifting device according to the invention can be installed with a single mounting operation. Likewise, anti-lift safety can be produced in a simple and economical way by producing a single piece.

According to another embodiment of the anti-lifting safety device of the invention, the attachment zone comprises a housing with at least one through opening for accommodating a fixing means. The housing with said at least one through opening serves firstly to guide the fastening means and also ensures that the fastening means will be protected vis-à-vis the frame, whereby it can exclude wear caused by the fastening means. The aforesaid housing can be made in such a way that a surface of the housing turned away from the covering area will serve as a stop vis-à-vis a vertical frame part of the frame. In other words, the surface of the housing diverted from the overlap zone can be made in the form of a right abutment surface which, when closing the leaf frame, will be brought into direct contact with the frame profile of the frame. giving frame. According to another embodiment of the anti-lifting safety device of the invention, the overlap area comprises a first partial area facing the attachment area and a second partial area diverted from the attachment area, each having a first width. In addition, there is provided a guide zone between the first and the second partial area with a second width which is larger than the first width of the first and second partial areas. In other words, the overlap zone has at least one enlarged guide zone which is made to be guided in an undercut of the profile of the leaf frame. Thanks to the realization of this special guiding zone, the anti-lifting safety device of the invention can be slid continuously along the vertical frame portion of the leaf frame, whereby an exact adjustment of the frame clearance can be achieved. leaf in relation to the giving frame. The present invention further relates to a window or a sliding door with a frame and at least one leaf frame, such that the leaf frame is mounted or capable of being mounted on a guide rail of the fixed frame with the possibility of sliding along at least one longitudinal groove. The sliding window or the sliding door comprises at least one anti-lift security according to the invention, which is detachably connected to the leaf frame and is made to at least partially cover the longitudinal groove of said at least one leaf frame. As already indicated above, it can be achieved by this that the door frame of the sliding door window will be mounted stably inside the frame, that is to say that a lifting of leaf frame out of the guide rails of the giving frame is not possible.

Said at least one leaf frame may, according to another embodiment, comprise an abutment at least on one of its vertical frame parts, a stop which is made to limit a sliding movement of the anti-lift safety along the vertical frame part. This stopper assists in the installation of the anti-lift safety device of the invention on the leaf frame of the sliding door window. In this assembly, the anti-lift safety is simply introduced into undercuts of the profile of the leaf frame, following which it will move by gravity along the vertical frame portion until reaching the abutment mentioned above. . According to a particularly preferred embodiment, the window or the sliding door comprises at least two anti-lift safeties according to the invention for each leaf frame. Here, one of the two anti-lift safeties is provided to cover the upper longitudinal groove of the leaf frame, while the other anti-lift security serves to cover the lower longitudinal groove of the leaf frame. Thanks to the installation of the anti-lift device according to the invention on each leaf frame of the window of the sliding door, it is furthermore prevented that the leaf frame can be detached by a rotational movement with respect to guide rails of said at least one sleeping frame. The present invention further relates to a method for mounting an anti-lift security according to the invention on a sliding window or a sliding door, the method comprising the steps of - applying the anti-lift security on a vertical frame portion of said at least one leaf frame such that the anti-lift security is mounted on the sliding leaf frame along the vertical frame portion; - Set up said at least one leaf frame in the giving frame; - slide the anti-lift security along the vertical frame portion as long as the anti-lift security covers said at least one longitudinal groove of the leaf frame; and - fix the anti-lift safety against the door frame with the help of a fastening element.

The method according to the invention makes it possible particularly particularly to cover the longitudinal grooves of the leaf frame. In particular, the method can be implemented at any time without problem by a single person. On the contrary, for the assembly of known anti-lift safeties of the state of the art, it is necessary to implement complex and expensive means. The anti-lift safety of the invention will be described in more detail in the following with reference to the embodiments illustrated in the figures. These figures show: FIG. 1: a perspective view of a first embodiment of the anti-lift security according to the invention; Figure 2 is a vertical section through a sliding window according to the invention, along a vertical frame portion of the leaf frame; Figure 3 is a section through the leaf frame of a sliding window according to the invention, along the anti-lift security according to the first embodiment of Figure 1; Figures 4a-c: a schematic representation of the method for mounting the anti-lift safety according to the invention on a sliding window; FIG. 5 is a vertical section through a sliding window according to the invention provided with two anti-lift safeties, along the vertical frame portion of a leaf frame; and FIGS. 6a-c: a schematic representation of the process for mounting the anti-lift safeties according to the invention on a sliding window according to FIG. 5. In the following detailed description of the figures, the identical or identical components will be assigned the same 10 reference numbers for the sake of clarity. A first embodiment of the anti-lift safety device 10 according to the invention for sliding windows and sliding doors is shown in FIG. 1. As shown, the latter comprises a covering zone 12 and a fixing zone 14. The overlap zone 12 and the fastening zone 14 are in particular integral, that is to say in one piece with one another. As can be seen, for example, in FIG. 2, the overlap zone 12 serves to cover an end region of at least one longitudinal groove 25 of the leaf frame 20. It will be noted here that the longitudinal groove 25 is shown in FIG. Figure 2 simply wears a better understanding. Of course, the lower end of the longitudinal groove 25 would not usually be visible in the view of FIG. 2, since this view would be covered by the overlap area 12 of the uplift security 10. It is possible to furthermore, in FIGS. 2 and 3, the fastening zone 14 serves to receive a fixing means 50, by means of which the anti-lifting device can be detachably fastened to the vertical frame portion of the leaf frame 20 In particular, as shown in FIG. 3, the fastening means 50 are screwed for this purpose into an outer insulating strip 23 of the vertical frame part 21. Here, the fastening means 50 is guided during screwing by the through opening 141 of the housing 142 of the fastening zone 14.

The overlap zone 12 shown in greater detail in FIG. 1 comprises in particular a first partial zone 121 facing the attachment zone 14, and a second partial zone 123 diverted from the attachment zone 14, each of which has a first width. . It is further provided between the first partial area 121 and the second partial area 103 a guide area 122 which is made wider than the first and second partial areas 121, 123. In other words, the guide area 122 has two lateral guide surfaces which protrude beyond the side edges of the first and second sub-areas 121, 123. These guide surfaces of the guide area 102 may be used to guide the anti-lift safety invention to undercuts 24 of the leaf frame 20, as can be seen for example in Figure 3. To further facilitate the introduction of the anti-lift 10 safety in the undercuts 24 of the leaf frame 20, the corners of the overlap zone 12 may in particular have chamfers 124, 125. In the sectional view of FIG. 2, it is also possible to see a horizontal frame part 32 of the frame 30. In the embodiment shown here, it comprises a first and a second guide rail 33 and 34, which serve respectively to guide at least one leaf frame 20 along its longitudinal groove 25. The door leaf 20 here suggested can be moved in sliding, by means of the upper longitudinal groove 25 shown in the direction of the plane of the figure vis-à-vis the guide rail 3. As can be seen, the lower end zone of the upper longitudinal groove 25 is spread relatively far of the guide rail 33, because of which there is a clearance between the guide rail of the frame giving 30 and the longitudinal groove 25 of the door frame 20, which game can be used for the establishment of the leaf frame 20 in the dormant frame 30. To subsequently prevent lifting the leaf frame 20 out of the frame 30, the free space provided at the longitudinal groove 25 is covered by the anti-lift safety. 10 of the invention. For this purpose, the anti-lifting device 10 is mounted, before hanging the leaf frame 20, on the vertical frame portion 21 of the leaf frame. In detail, the anti-lifting device 10 is introduced for this purpose with its guide zone 122 in the undercuts 24 (see also FIG. 3) of the vertical frame part. Here, the first width of the first partial area 121 is chosen such that the first partial area 121 fits exactly between the profile segments of the undercut 24 of the vertical frame portion 21. As will be explained further in detail below with reference to FIGS. 4a to 4d, after having hung the leaf frame 20 in the frame 30, the anti-lifting device 10 of the invention is slid in the direction of the longitudinal groove 25 as far as the zone cover 12 sufficiently covers the free space between the longitudinal groove 25 and the guide rail 33. In this position, the anti-lift device 10 of the invention is connected by means of a fastening element 50 (for example a screw fastening) with the surface of the vertical frame part 21. The attachment of the anti-lift device 10 of the invention to the vertical frame part 21 of the leaf frame 20 can be partly also seen in the sectional representation of Figure 3. It can be seen from this figure that the fastening means 50, guided by the through opening 41 of the attachment zone 14, is introduced into an outer insulating strip 23 of the vertical frame portion 21. The housing 142 of the fastening zone 14 is here made in such a way that it covers the end region of the fixing means 50 and simultaneously constitutes an abutment surface for lateral contact profiles 35 and 36 of the In other words, the housing 142 of the fastening zone 14 has a surface which is turned away from the overlap zone 12, which serves as an abutment surface with respect to the contact profiles 35, 36 reported on the vertical frame portion 31 of the frame 30. As already mentioned above, it is possible to see in FIGS. 4a to 4c a method according to the invention for mounting an anti-lift security on a sliding window or a window. e sliding door. First of all, as shown in FIG. 4a, the anti-lifting device 10 is mounted on the vertical frame part 21 of the leaf frame 20. For this purpose, the anti-lifting device 10 is inserted into the counter-beams. 74 0 7 9 struts 24, formed by the profiles, of the vertical frame portion 21. As seen in Figure 4b, is then assembled the leaf frame 20, that is to say two parts of frame 21 are respectively connected to two horizontal frame portions 22 of the frame 5 of leaf 20, so that a rectangular leaf frame results. It can further be seen that the vertical frame portion 21 and the horizontal frame portion 22 of the leaf frame 20 together form a longitudinal groove 25 which serves to receive the guide rail 34 of the horizontal frame portion 32, illustrated in FIG. FIG. 4c, of the frame 10 giving 30. In order to reach the structure illustrated in FIG. 4c, said at least one leaf frame 20 is put into place in the fixed frame 30 in such a way that the guide rail 34, not shown here, the frame 30 engages in the longitudinal groove 25 of the leaf frame 20. After setting up the leaf frame 20 in the frame 30, the anti-lift 10, which is already in the frame part vertical 21 of the leaf frame 20, is slid up as long as the anti-lift 10 covers said at least one longitudinal groove 25 of the leaf frame 20, as indicated by the arrow pointing v in Figure 4c. Finally, the anti-lifting device 10 is fixed, by means of a fastening element 50, in the position illustrated in FIG. 4c on the vertical frame part 21 of the leaf frame 20. As the anti-lifting device 10 is realized in particular in one piece, this procedure for mounting the anti-lift security can be implemented very simply also by one person. For this purpose, it is only necessary to slide the anti-lift safety device 10, after setting up the leaf frame 20 in the frame 30 giving 30, upwards in the direction of the longitudinal groove 25, and to fix the security anti-raising 10 with the fastening element 50 on the leaf frame 20. It can be seen in Figure 5 an embodiment of the sliding window according to the invention with two anti-lift safeties 10. The two anti-lift safeties 10 serve here on the one hand to cover the upper longitudinal groove 25 and on the other hand to cover the lower longitudinal groove 26 of the leaf frame 20. The two anti-lift safeties 10 are made in particular identical and, similarly to the procedure described with reference to Figures 4a to 4c, they are fixed on the vertical frame portion 21 of the leaf frame. To improve understanding, FIGS. 6a to 6c illustrate again the mounting of the two anti-lift safeties according to FIG. 5. The representations of FIGS. 6a to 6c are substantially similar to the representations of FIGS. 4a to 4c. It should be noted, however, that in FIGS. 6a to 6c it is possible to see a stop element 40 in the middle of the vertical frame part 21, which serves to prevent the anti-lift device 10 from escaping during the assembly of the frame. In detail, it can easily be seen in FIG. 6a that the anti-lifting device 10 penetrates, after insertion into the vertical frame portion 21, under the effect of gravity, into the vertical frame portion 21 as far as it reaches the stop element 40. Similar considerations apply to the lower lift up safety 10, which is made to cover the lower longitudinal groove 26 of the leaf frame 20. The present invention is not limited to Embodiments illustrated in the figures, but it results from a combination of all the features disclosed herein.25 List of references 1.
