Description

[0001] The invention relates to a window or door with a frame having a glazing block for the insertion of a glazing. Technical field

[0002] To secure glazing in a window or door, several glazing blocks are first inserted around the perimeter of the frame's rebate. These fill the rebate up to the height of the glazing bead groove. The glazing is then inserted over the glazing bead groove until it abuts the rebate. There is still some play between the glazing and the glazing blocks. To compensate for this play, glazing blocks are inserted around the perimeter between the glazing and the glazing blocks. Glazing blocks are available in different heights, allowing the glazing to be shifted slightly within the glazing plane and positioned individually. State of the art

[0003] Such a system is described, for example, in EP 1877640 B1. In this system, the rebate area is wider than the glazing, so that the glazing rests on the glazing blocks over a wide area and a glazing bead or retaining strip can be easily inserted into the retaining strip to fix the glazing.

[0004] DE 202010013228 U1 discloses a window frame with an inner and an outer shell, which are connected by insulating webs. A glazing block is connected to the insulating web, which faces the rebate area, via a clip connection. The glazing block rests on the inner edge of the glazing bead groove, on the side facing the rebate area. The glazing bead groove is completely open at the top and is not vertically covered by the glazing block. The glazing is located entirely between the glazing block feet, which serve to support the glazing block in the rebate area.

[0005] DE 29618315 U1 also shows a window with a single or alternatively multi-part glazing block, in which the glazing is completely within the rebate area and does not vertically extend beyond the glazing bead retaining groove.

[0006] To optimize the thermal insulation of houses, triple glazing is often installed instead of double glazing, resulting in deeper glazing.

[0007] When a thick or deep pane of glass is installed in a narrow frame, the problem arises that the glazing extends at least partially beyond the glazing bead groove, meaning that part of the glazing is not directly supported by the frame. If the glazing block extends over the entire depth of the glass, it does not rest fully on the glazing block bridge; the area of ​​the glazing block not supported by the bridge is subjected to bending stress. While the glazing is also held by the clamping mechanism on the side and top frame profiles, thus supporting some of the weight, the support on the bottom frame profile is much more robust. In the long term, this known system can lead to weight-related deformations in the portion of the glazing that is not directly supported from below.

[0008] Furthermore, a problem can arise when using the glazing bead if it hits the glazing block. In unfavorable cases, the glazing bead can no longer be used because the space required for installation is taken up by the glazing block.

[0009] In a short glass block, at least one pane of the glazing is held only by the actual glazing unit. Task

[0010] The object of the present invention is therefore to create a glazing block, particularly for wide glazing in narrow frames, which ensures support of the entire glazing on the frame and / or the trouble-free use of a glazing bead. Description of the invention

[0011] The problem is solved by a window or door with the features of the independent claim. A window or door has a conventional frame with glazing blocks for glazing. The frame is formed from interconnected frame profiles. The frame profile includes, among other things, a rebate and a glazing bead groove. The glazing is connected to the frame all around by means of glazing blocks and is fixed by means of glazing beads that engage in the glazing bead grooves of the frame profiles. Each glazing block comprises at least one glazing block bridge and at least one glazing block, which fills the space between the glazing and the glazing block bridge, thus fixing the glazing.A glazing block bridge is typically understood to be a component that fills the rebate area in a base profile up to the height of the glazing bead groove, while the component that fills the space between the glazing block bridge and the glazing is usually referred to as a glazing block. However, a glazing block bridge can extend beyond the glazing bead groove or remain below the level of a maximum of two mutually perpendicular frame base profiles. Optionally, the glazing block bridge and glazing block can also be designed as a single unit.

[0012] The glazing has a height and width in the main plane, while perpendicular to this it has a depth determined by the number of panes, their depth, and their spacing. Optionally, the glazing projects vertically, at least partially, beyond the glazing bead groove; this means that a direct downward force transfer is not possible, as the glazing bead must be accommodated there. According to the invention, however, it is also possible to use narrower glazing.

[0013] According to the invention, at least the glazing blocks on the lowest frame profile supporting the glazing bear substantially the entire depth of the glazing. Consequently, the glazing blocks may project slightly beyond or be recessed below the glazing. Each pane of a multi-pane glazing should rest at least partially on the glazing blocks so that the entire weight of all panes is transferred into the glazing blocks.

[0014] The glazing blocks have a beveled outer surface on the side facing the glazing bead. This bevel extends from the glazing towards the center of the frame profile, towards the rebate area. On the side opposite the glazing, this outer surface reaches the frame profile and rests upon it. The glazing blocks on the lowest frame profile, which supports the glazing, project vertically, at least partially, beyond the glazing bead groove. The beveled outer surface of the glazing blocks allows a glazing bead to be inserted into the groove, and the angled shape facilitates insertion, particularly when the bevel ends at the transition from the groove edge to the groove itself. This allows the entire weight of a wide pane of glass to be transferred downwards into the frame profile under the force of gravity.

[0015] Advantageous configurations result from the characteristics of the dependent claims.

[0016] It is therefore advantageous if the glazing blocks have glazing block feet that extend to the inner edge of the glazing bead retaining groove, facing the rebate area, and rest upon it. This ensures that the maximum width within the frame base profile is utilized for support.

[0017] Optionally, a glazing block and a glazing block can be configured as a single unit. This assembly, consisting of the glazing block and glazing block, can, for example, be manufactured as a single injection-molded plastic part. This facilitates the positioning accuracy of the glazing blocks and simultaneously optimizes the force distribution within the assembly.

[0018] An optional embodiment of the invention provides that the outer surface of the glazing block described above is concavely curved. This facilitates the installation of the glazing bead. Another optional embodiment of the invention provides that the outer surface of the glazing block described above is straight; in this case, compared to the previously described option, the glazing block is more robust, which improves its load-bearing capacity.

[0019] If the outer edge of the glazing block transitions directly into the groove of the glazing bead and the inner edge of the groove, the glazing bead can be inserted particularly easily. A slight horizontal offset of up to 2 or 3 mm is acceptable in this case. Brief description of the drawing

[0020] The invention is explained in more detail below with reference to exemplary embodiments and the drawings. The drawings show: Fig. 1 shows a narrow frame with wide glazing according to the prior art; Fig. 2 shows a frame according to the invention with wide glazing in a first embodiment; Fig. 3 shows a frame according to the invention with wide glazing in a second embodiment; and Fig. 4 shows a frame according to the invention during the assembly of the glazing bead in six stages.

[0021] The same reference symbols in different figures have the same meaning. Not all reference symbols are shown in all figures.

[0022] Figure 1Figure 1 shows a section of a fixed glazing unit 1 with a pane of glass 6, which in this case has three parallel panes, and a frame profile 2. A glazing block 5, extending to the inner wall of a glazing bead groove 4, is inserted into the rebate area 3 of the frame profile 2. A glazing block 7 is located between the glazing block 5 and the pane of glass 6. The pane of glass 6 extends to the overlap 18 of the frame profile 2, where a seal 9 seals the contact between the pane of glass 6 and the overlap 18. A glazing bead 8 is engaged in an undercut 20 of the glazing bead groove 4 by means of a locking lug 19 belonging to the glazing bead 8 and clamps the pane of glass 6 in place via a seal 9. The block bridge 5 has locking lugs 13 on the side of the overlap 18, as well as locking lugs 14 on the side facing the glazing bead retaining groove 4.

[0023] It can be seen that the right pane of glazing 6, which faces the glazing bead 8, does indeed rest on the glazing block 7, but the right part of the glazing block 7 is not supported by the block bridge 5. As a result, the weight of the right pane of glazing 6 cannot be transferred directly downwards, as is the case with the other two panes. This leads to bending stresses.

[0024] At the same time, the lower right edge of the glazing block 7 abuts the wall of the glazing bead 8 facing the rebate area 3. Even without a visualization, it is clear that the glazing bead 8 can only be inserted with considerable force, deforming the aforementioned wall of the glazing bead 8.

[0025] The frame according to the invention Figure 2 differs from the one in Figure 1by the modified glazing blocks 5, 77. The glazing 6 is wide enough to extend from the overlap 18 of the frame base profile 2 to beyond the glazing bead retaining groove 4. The glazing 6 rests completely on the glazing block 77 according to the invention. The glazing block 77 has a sloping outer surface 10 on the side facing the glazing bead 8, which extends slightly beyond the glazing 6 towards the glazing bead 8 on the side facing the glazing 6, and the outer surface 10 of the glazing block directed towards the glazing bead 8 runs continuously towards the center of the frame base profile 2 in the direction of the rebate area 3. The glazing block 77 has a concave profile in the area of ​​this glazing block outer side 10 which is directed towards the glazing retaining strip 8 and is therefore curved inwards in the glazing block 77.Furthermore, the glazing block 7 has a glazing block foot 11, which extends on the outer side 10 of the block bridge to the inner groove edge 12 of the glazing bead retaining groove 4, which is directed towards the rebate area 3, and rests there on the groove edge 12.

[0026] This offers an advantage compared to the prior art: all three panes of the glazing 6 can transfer their weight downwards via the glazing block 77 and the block bridge 5, thus subjecting the blocking to less bending stress and more compression stress.

[0027] Furthermore, the glazing bead 8 can be easily inserted, as the concave shape of the outer surface 10 of the glazing block provides sufficient space for this. The outer surface 10 of the glazing block transitions directly into the groove 4 of the glazing bead holder and the inner edge 12 of the groove, so that the locking lug 19 of the glazing bead 8 can slide along the outer surface 10 of the glazing block into the groove 4 of the glazing bead holder and lock into place.

[0028] The exemplary embodiment further shows a central seal spar 15 for receiving a central seal 16, which Figure 2 in its original state. At those points where a block bridge 5 is inserted, the central seal 16 is partially removed.

[0029] The frame according to the invention Figure 3 differs from the one in Figure 2through the glazing block 77, which has a straight course in the area of ​​the outer side 10 of the glazing block directed towards the glazing retaining strip 8, so that the glazing block base 11 is a little more massive, but the glazing retaining strip 8 can still be used without any problems.

[0030] In both embodiments according to the invention, glazing block 77 and block bridge 5 can be separate components; however, glazing block 77 and block bridge 5 can also be designed as a single component.

[0031] The lower glazing block 5, 77 of the lowest frame profile 2 of the frame absorbs most of the weight of the glazing 6, while the upper and side glazing blocks 5, 7 primarily serve to ensure that the glazing 6 is held in the frame without play.

[0032] If the glazing blocks 5, 7, 77 are two-part, then glazing block bridges 5 are first inserted into the rebate area around all four sides of the frame. The glazing blocks 77 according to the invention are then inserted on the lowest frame profile 2. The vertical play of the glazing 6 in the frame is compensated for according to the invention by the individual width of the glazing blocks 7 on the uppermost frame profile 2. The two side frame profiles 2 remain unchanged from the prior art.

[0033] If the glazing block 5, 77 is a single piece at the bottom, this single-piece glazing block 5, 77 is used at the bottom, while conventional glazing block bridges 5 are used at the top and sides. The glazing 6 is then inserted into the frame up to the overlap 18. At the top and sides, the glazing 6 is now fixed in place by using appropriate glazing blocks 7. Here, too, the vertical movement of the glazing 6 in the frame is compensated for by the individual width of the glazing blocks 7 on the uppermost frame profile 2.

[0034] The mounting of the glass retaining strip 8 is the same in both embodiments and is described in Figure 4 Therefore, both outer sides of the glazing blocks are shown 10. The glazing 6 and glazing blocks 5, 77 are already installed here.

[0035] In step I, the glazing bead 8 is initially positioned so that the locking lug 19 rests on the outer edge of the groove 21 of the glazing bead retaining groove 4, the edge furthest from the rebate area 3. In step II, the glazing bead 8 is moved into the glazing bead retaining groove 4 with the locking lug 19. Steps III to V show further movements in which the locking lug 19 slides into the glazing bead retaining groove 4. Step VI shows the final state, in which the locking lug 19 engages in the undercut 20 of the glazing bead retaining groove 4 and a horizontal underside 22 of the glazing bead 8 rests on the outer edge of the groove 21 of the glazing bead retaining groove 4. It is clearly visible that the glazing bead 8 can slide past the glazing block 77 on the angled outer surface 10 of the glazing block.

[0036] The figures show a fixed glazing unit 1 in which the frame base profiles 2 are in contact with a masonry wall by means of profile feet 17. The invention can also be used for sash frames. legend
