DESCRIPTION

Glazing strip that can be placed under pressure on the edge of a glazing panel

The invention relates to a profile bar to be locked in a panel. The invention relates to the panel structure of a glazing system.

The prior art glazing systems, which are used, among other things, on balconies, are installed in buildings. The systems usually comprise a top profile and a bottom profile, which are used as guide tracks and within which the necessary parts of the mobile guide track are placed, between which, in turn, the glass sheets are suspended individual The glass sheets form walls and doors, as well as limit the space or protect it, for example, from climatic conditions, for example, on balconies or terraces, or divide the sword into several parts and subdivide the spaces, for example, into business rooms or facilities. Usually, the profiles extend in the horizontal direction and are attached to the building structures. By means of guide track pieces, the individual glass sheets can be moved, and also open and close around a vertical axis of rotation. Glass sheets can be transferred and piled up when opened. Some known glazing systems are disclosed, for example, in EP 1892362 A1 and EP 188996 A1.

The glass sheets, or corresponding panels, are normally disconnected and, when the panel is rotated, the panel guide element must be locked in position so that the panel does not adopt an inclined position. During blocking, the guide element is blocked, for example, with an adjacent guide element, according to WO 03/042482 A1 or, for example, with a blocking element within a top profile, which is, for example , a basin or a last, in which the guide element or a part thereof is placed during the rotation of the panel.

The panels usually comprise profile bars that are normally provided both at the upper edge and at the lower edge of the panel. The profile bar is normally an aluminum profile manufactured by extrusion. The guide elements and, if necessary, also the guides, are attached to the profile bar.

The profile bars are normally fixed to the panels such that the panel is placed in a slot in the profile bar, and the profile bar is held in place by compression. Normally, the fixing is also secured by means of glue and fixing elements, for example, screws, which extend through a hole made in the panel. Some examples of profile bars and their fixing are disclosed in WO 03/040505 A1, WO 03/040510 A1 and WO 02/29177 A1.

Fixing a profile bar to a glass sheet can be a laborious and time-consuming operation. Problems can be caused, for example, by machining the holes in the glass sheet, because at the time of making the holes, the glass sheet that is transferred, for example, by means of a conveyor in a factory or A workshop must be stopped and aligned precisely in two perpendicular directions, which slows down the manufacturing process. It is difficult to combine these stages, for example, with the grinding of the edges or other processing of the glass sheets in a single effective operation. The use of screws will fasten the fixing of the profile bar to the glass sheet, but also slows down the installation work.

US-A-5373672 shows an example of a mounting section fixed to a glass sheet. The mounting section can be pre-folded and have elevations to lock the glass panel in position.

A solution will be presented to eliminate the problems presented above. More precisely, the profile bar to be locked with the panel, according to the solution according to the invention, will be presented in claim 1. The panel structure for a glazing system, according to the solution according to the invention, will be presented in claim 4.

The solution will allow the joining of the profile bar to a glass sheet or to a panel, in a way that is easy and fast with respect to the installation. The solution will allow the processing of glass sheets for fixings, for example, in a factory, so that the processing procedure is significantly faster than the prior art procedures. The new processing procedure can be easily integrated into other glass sheet processing. Another significant advantage is the secure way to fix the profile bar, so that the use of fixing screws will not be necessary.

Another significant advantage in an example of the solution is the fact that the fixing of the profile bar to a glass sheet or panel by pressure requires less force than the detachment of the profile bar, pulling in the opposite direction. As a result, installation is easy and fixing is safe and reliable.

Another advantage in some examples of the solution is the fact that the installation of the profile bar on the glass sheet, and its detachment, can also be performed by sliding in the direction of the profile bar.

In an example of the solution, the glass sheet comprises blocking forms, in particular one or more open grooves or channels, in which the blocking elements of the profile bar are placed. Preferably, the profile bar comprises a structure that presses the glass sheet against the locking elements. Said structure and / or blocking element can be selected so that they yield during installation. In another example of the solution, the profile bar to be used comprises an elastic locking element that is a projection, and which is placed in a shape on the glass sheet and effectively prevents the removal of the glass sheet.

A particular advantage of the solution is the fact that the machining of the locking form on the glass sheet will not require the stopping of the glass sheet, which speeds up the processing procedures to a significant degree. The alignment of the glass sheet in relation to the machining of the locking form is significantly facilitated, since it will be sufficient for an extreme surface of the glass sheet to be placed precisely and in a desired manner, for example, against a cap at the time of mechanization.

The solution can be applied in crushing systems that are used indoors or outdoors. The solution can also be applied in various systems in which different panels and panel materials are used.

The solution will be illustrated in the following description by means of some examples and with reference to the attached drawings, in which:

Figure 1 shows a glazing system according to a known example in a main view, Figure 2 shows a profile bar according to an example of the solution in a cross-sectional view,

Figure 3 shows a profile bar that does not belong to the present invention in a cross-sectional view,

Figure 4 shows a glass panel or sheet according to an example of the solution,

Figure 5 shows a profile bar according to Figure 2 and a glass panel according to Figure 4, fixed together,

Figure 6 shows a cover according to an example of the solution, and

Figure 7 shows a profile bar according to Figure 2, a glass sheet according to Figure 4 and a cover according to Figure 6, fixed together.

Figure 1 shows a panel and a prior art panel system which is at the same time, for example, a glazing system, for example, for balconies, or a wall limiting a space. The system normally comprises several successive glass sheets that can be moved. The panels 1 are normally rectangular, are normally in a vertical position and form a closed wall or a large window when placed one after the other. They can be transferred in the direction of the guide tracks, which is usually the horizontal direction. The panels 1 can be opened in a position that is normally perpendicular to the closed position shown in Figure 1. In the open position, the panels 1 can be placed close to each other, and can be stored, for example, on one side of a balcony, where they have first moved along the guide tracks. The upper guide track 3 and the lower guide track 2 are placed in the horizontal direction and, among other things, an upper guide track piece 4 and a lower guide track piece 5 are placed therein and are movable on the guide tracks, the panels 1 being fixed from above and below between the guide track pieces, and the panel is in the vertical plane. The guide tracks are normally extruded aluminum profiles and are provided with a longitudinal continuous groove or channel for the parts of the guide track. The panel 1 is preferably formed by a glass sheet whose lower and upper edges are provided with profile bars 7 and 8, to which, in turn, the guide elements 4, 5 and 9 are fixed, for example, by hinge pins 6, 11 and 15 or shafts.

In the guide elements and their closures, it is possible to apply several prior art solutions. The panel 1 and / or the guide tracks 3, 4 are equipped with the guide elements and prior art means, for example, the guide elements 13, 14 and the stops 10 and 12, whose functionality facilitates or ensures the panel lock in position, so that the panel can be turned fully open. To open the panel 1, an opening 16 is arranged next to the guide track 3, through which the piece of the guide track 9 can exit the guide track during rotation.

Figure 2 shows an extruded aluminum profile according to the example presented, which is used as a profile bar that is fixed to the panel, for example, in the system shown in Figure 1. The profile shapes, visible in the section transverse, they extend evenly in the longitudinal direction of the profile. Different parts of the system, in particular, the hinge pin, are fixed to an elongated groove 19 or channel. The profile bar 20 also comprises an elongated groove 21 or channel for the panel, placed on the opposite side of the profile bar 20 with respect to the groove 19. The side walls 21a and 21b, which limit the groove 21, are placed against the side surfaces 22a and 22b of the glass panel or sheet 22 (see Figure 4), and the transverse end wall 21c is placed against the narrow transverse end surface 22c of the glass sheet 22, near the same or separated Of the same. In addition, the groove 21 comprises an opening 18, through which the panel is installed. The end wall 21c and the end surface 22c are preferably parallel. In addition, the profile bar 20 comprises a variable number of other walls that are adjacent to the side walls 21a, 21b or to the end wall 21c and, if necessary, in parallel therewith. Normally, the profile bar comprises the outer walls 20a and 20b,

which are connected in a seamless manner by means of struts to the side walls and to the extreme wall, and which are also profiled, if necessary. Closed or open chambers are left between the walls. It is also possible that, for example, the side wall 21a is simultaneously the outer wall of the profile bar 20.

In the example of Figure 2, the side wall 21b is an elastic structure and is simultaneously a blocking element for locking the panel or glass sheet 22 in its position. The side wall 21b is placed in a groove 25 machined in the glass sheet and mechanically prevents the detachment of the glass sheet. The side wall 21b is connected as a projection to the profile bar 20, and extends from the opening 18 towards the end of the wall 21c, essentially in the direction of the side wall 21a and the glass sheet installed in the groove 21 Simultaneously, the side wall 21b extends towards the end surface 22c of the glass sheet. The end 23 of the side wall 21b is free and is capable of bending in a direction essentially perpendicular to the side wall 21a and the glass sheet. The groove 21 is sized so that the installation of the glass sheet in the groove by pressure will force the end 23 to yield, which increases the friction between the glass sheet and the end 23. The perpendicular distance between the free end 23 and the side wall 21a is thus less than the thickness of the panel or the glass sheet.

The locking of the glass panel or sheet in its position is actually carried out, so that the end 23 is placed in a groove 25 in the glass panel 22 (see Figure 4). In order to remove the glass panel, in turn, a greater force will be necessary, because when the glass sheet rises from the profile bar 20, the end 23 is strongly supported in the groove 25. The shapes of the groove 25 and the end 23 corresponds so that the groove 25 does not push the end 23 to the side, but they are firmly fixed together. The shapes can be combined so that a given, relatively large force will be needed to move the end 23 out of the groove 25, or else the side wall 21b, when yielding, would otherwise allow such movement of the end 23, which would displace the end 23 out of the groove 25. The shapes can even be selected so that the end 23 is tighter, against the glass sheet 22, rather than transversely, away from it. The yield is also influenced by the length of the side wall 21b and the thickness of the material. The blocking can be improved by completing the side wall 21b, for example, with flanges that correspond to the end 23 in its shape and functionality, and which are placed in the grooves in the panel or glass sheet.

The side wall 21a is attached at its two ends to the profile bar 20, but even this can be arranged so that it yields during the installation of the panel or glass sheet. The side wall 21a can also be provided with flanges that are placed in the grooves in the panel. Usually, a glue layer is applied between the side wall 21a and the panel, to ensure blockage.

Figure 3 shows an extruded aluminum profile according to another example which, however, does not belong to the present invention, and which is used as a profile bar 20 to be fixed to the glass panel or sheet, for example, in the system shown in Figure 1. Due to the similarity in functionality, reference numbers corresponding to those in Figure 2 are used. In this example, the side wall 21b is an elastic structure that yields in a direction essentially perpendicular to the side wall 21a and the glass sheet, or a normal side wall that only yields to a certain extent, or nothing at all. The side wall 21b is also a locking element that locks the panel in position. The side wall 21b is placed in a corresponding slot 25, machined in the panel or glass sheet 22 (see Figure 4), and prevents the panel from detaching mechanically. The side wall 21 b comprises one or more flanges 24 placed in a groove 25 in the glass panel or sheet. The side wall 21 b is attached at its two ends to the profile bar 20 and is essentially parallel to the side wall 21a and, for example, to the glass sheet 22. One or more flanges 24 are provided in the central part of the side wall 21b.

In the example of Figure 3, the side wall 21a is an elastic structure that yields in a direction essentially perpendicular to the side wall 21b. The side wall 21b is attached at its two ends to the profile bar 20, and the flange 24, or the flanges, are essentially placed at the height of the center of the side wall 21a. The groove 21 is sized so that the installation of the panel in the groove 21 by pressure will force the side wall 21a to yield, which increases friction between the panel and the side wall 21a. The perpendicular distance between the flange 24 and the side wall 21a is thus less than the thickness of the panel. A glass sheet 22 according to Figure 4 is locked in position, in such a way that the flange 24 is placed in the groove 25 on the glass sheet 22. During installation, the side wall 21a, or the side wall 21b , yields, or both yield, or yields the entire profile bar 20, depending on the structure of the profile bar. Sufficient force will be needed to remove the glass sheet 22, since, when the glass sheet 22 is raised from the profile bar 20, the flange 24 is in the groove 25. The shape of the groove and the flange can be adapt in such a way that lifting the glass sheet out of the profile bar will require a force greater than its installation. The shape can be mounted so that a relatively large force is needed to remove the flange from the groove. The yield is also influenced by the length and thickness of the side wall. The blocking can also be improved by complementing the side wall 21a with flanges that coincide with the flange 24 in its shape and functionality, and which are placed in grooves in the panel or glass sheet. In this case, the grooves whose functionality corresponds to the groove 25 are provided on both sides of the glass sheet. In view of the strength of the glass sheet, the grooves are preferably provided on a side surface of the glass sheet only.

of Figure 1, and to which, for example, a profile bar is fixed according to Figure 2 or 3. The glass sheet 22 is usually rectangular in shape and, for example, its end surface 22c is preferably perpendicular to the surfaces lateral 22a and 22b. The glass sheet 22 is made by cutting, and its edges 17, which are placed at the Intersections of the lateral surfaces and the end surface, are usually ground at an angle of approximately 45 degrees. The glass sheet 22 also comprises two other perpendicular end surfaces, of which the end surface 22d is shown.

According to the prior art, cylindrical holes are generally drilled in the glass sheet, which extend through the glass sheet in the perpendicular direction, and which are used in fasteners that hold the glass sheet to a profile bar by, For example, screws. The glass sheet 22 according to the example of Figure 4 comprises an engraving, a channel or a groove 25, by means of which the glass sheet 22 is attached to the profile bar 20. The groove 25 is straight and long or elongated, in which its length in the direction of the end surface 22c is greater or multiple in relation to the width of the groove 25. There may be several grooves, and they are parallel, as outlined by a dashed line in Figure 4 The groove is made by machining the glass sheet by means of, for example, a rotating diamond disk. The groove can also be made in another way, for example, by means of a mandrel tool, so that the cross-sectional shape of the groove can vary and comprise circular, curved or straight walls, according to needs. As a process, the machining can be continuous, if the groove is continuous and extends from one edge of the glass sheet to another, that is, on the side surface 22a to the end surface 22d, so that the glass sheet does not must stop during machining time. With respect to the machining process, it will be sufficient that, for example, the lateral surface 22c is placed against an alignment stop, along which the end surface 22c slides or rolls at the same time when the glass sheet 22 moves and a tool mechanizes the glass sheet that passes. In this case, the tool can be static, but obviously it is also possible to use a moving tool and stop the glass sheet during the machining time. Despite the arrest, the process is faster than the known technique, because the alignment is simple.

The groove 25 is preferably continuous and open, at least at one end, where the installation of the profile bar for the glass sheet 22 is also possible by pushing the profile bar on the glass sheet, by a movement that is parallel to slot 25. Slot 25 is preferably open at its two ends, as shown in Figure 4. Therefore, it will not be necessary to stop the glass panel or lift the tool during machining and when the glass sheet is it is moving, and it will not be necessary to align the tool precisely to the start and end points of the groove. Preferably, the groove 25 is continuous in the longitudinal direction of the profile bar 20, as are also the blocking structures and the shapes in the profile bar 2; serving end 23 and flange 24 as examples. The perpendicular distance of the groove 25 from the end surface 22c is essentially equal to or shorter than the distance between the end 23 or the flange 24 and the end surface 21c.

The groove 25 may also consist of two or more successive and parallel grooves but, in this case, the part that is placed between the successive grooves must be removed from the side wall 21 b, the end 23 or the flange 24 of the profile bar 20, for example, by cutting or drilling. Alternatively, the profile bar consists of several parts that are placed one after the other, which may differ from each other in their cross-section, their fixing procedure and their structure.

In one example, the open end of the profile bar 20 is closed with a cover 26 shown in Figure 6, which is usually a cover, a plug or a cover made of plastic. The cover comprises the projections 26a and 26b which are connected, for example, by friction to the walls or chambers in the profile bar. In addition, the cover comprises a wedge 27 whose thicker end is attached to the cover, and whose sharpest end extends away from the cover, essentially in the perpendicular direction. The wedge 27 is pushed under the glass panel or sheet, being placed, for example, between the end surface 22c of the glass sheet 22 and the end wall 21c. When the cover 26 is inserted, the wedge 27 pushes the glass sheet 22 up and the wedge 25 is firmly placed against the end 23 or the flange 23. The presented joint will eliminate any free space between the profile bar and the panel, and the profile bar cannot be moved uselessly with respect to the panel. The cover 26 of Figure 6 also comprises a slot 26c open at the top and on one side to receive a corner of the glass sheet 22.

Figure 7 shows a panel structure according to an example, which is used, for example, in a system according to Figure 1. The structure of the panel 28 comprises a panel or glass sheet 22, a profile bar 20 and a cover 26, as presented above. The total length of the profile bar 20 may be less than the width of the glass sheet 22. In the example of Figure 7, the profile bar 20 does not extend fully to the end surface, since a cover is provided 26 in the corner of the glass sheet.

Figure 5 shows a profile bar 20 of Figure 1 and a glass sheet 22 of Figure 4, fixed together. As shown in Figure 5, the end 23 is placed in the groove 25 in the glass sheet 22. The functionality of the lock is presented in more detail in the description relating to Figure 2.

The invention is not limited solely to the embodiments presented above. The invention is applied within the scope of the appended claims. The material for the manufacture of the panel is selected according to the

needs, and can include transparent or opaque alternatives. In this specification, a variant made of glass is disclosed in particular. The most precise shapes and dimensions of the profile bar and profiles may vary as desired.
