Description

[0001] The invention relates to a sliding window or a sliding door.

[0002] More particularly, the present invention relates to a sliding window or door having a slidable door leaf in a fixed frame, which is movably supported in the fixed frame by one or more roller sliders.

[0003] In particular, the invention relates to a sliding window or sliding door having a frame consisting of profiles, each profile comprising two half-shells thermally separated by an intermediate thermal insulator, wherein the thermal insulator also connects the two half-shells to one another, wherein notches are provided in the frame, in which notches glass panels or the like are placed, and wherein the frame is supported by rollers by means of which the frame can be moved on rails or the like, for example in grooves of an underlying profile to which the frame is fixed.

[0004] Any reference to sliding windows should be understood to also refer to sliding doors.

[0005] Many such sliding windows are known in the prior art, but they can still be improved.

[0006] The current trend is that larger and larger sliding windows are used, whereby the glass panels also adopt larger and larger dimensions and greater thickness (for example because double or even triple glazing is used).

[0007] The result is that the weight of such glass panels is increasing.

[0008] Furthermore, the thermal insulation of the profiles of sliding windows has to meet increasing requirements, so that the dimensions of the thermal insulation used between the half-shells have become larger.

[0009] Typically, thermal insulators are made of low-strength materials and are therefore less suitable or not suitable at all for absorbing certain loads.

[0010] In short, on the one hand, the load exerted by the weight of the glass panel on the profile of the sliding window increases, while on the other hand, the profile becomes weaker due to the larger dimensions of the intermediate insulator.

[0011] This creates problems when transmitting the forces that occur to the rollers of such sliding windows or doors.

[0012] Therefore, an object of the present invention is to provide a solution to solve one or more of the above mentioned or possible other disadvantages.

[0013] More specifically, the present invention is directed to an improved sliding window or door in which the load from the weight of the panel is transferred to the rollers of the sliding window or door, thereby reducing the impact on the door leaf.

[0014] Another object of the invention is to make possible the further development of sliding windows which are larger and have heavier glass panels than was possible with the prior art.

[0015] A further object of the invention is to provide a solution which in no way impairs the thermal insulation properties of the profiles used.

[0016] To this end, the present invention relates to an improved sliding window or sliding door with a door leaf, which has a door leaf frame composed of a door leaf profile, each door leaf profile comprising two half shells, which are thermally connected to each other via an intermediate thermal insulator, wherein the door leaf frame comprises a groove and one or more glass bead supports, and a panel supported by the one or more glass bead supports in the groove, and wherein the door leaf frame is supported by one or more roller boxes with rollers, wherein the one or more glass bead supports are separated from the roller boxes, characterized in that at least one glass bead support comprises a feed-through portion for transferring the weight of the panel or part thereof to at least one associated roller box, and the feed-through portion extends through the bottom door leaf profile to the roller box.

[0017] A great advantage of such a sliding window or sliding door according to the invention is that it comprises a glazing strip support, with which the weight of the panel is transferred directly to the rollers via the bottom profile of the leaf frame, contrary to the situation with known sliding windows, in which the weight of the panel is transferred to the rollers via the half shells.

[0018] As is known, preferably the thermal insulator is located vertically, or virtually vertically, below the panel.

[0019] According to the invention, preferably a glazing bead support is used, the feed-through portion of which extends at least partially through the thermal insulation as far as a roller, which is also located vertically or virtually vertically below the panel.

[0020] In this way, the weight of the panel is transferred to the rollers substantially according to the vertical direction.

[0021] This is certainly a very efficient way to support the weight.

[0022] In a preferred embodiment of a sliding window or sliding door according to the invention, the glazing bead support of the sliding window comprises a plate-shaped portion for supporting a panel edge, whereby the feed-through portion is formed by one or more protrusions extending a certain length in a complementary channel provided in the thermal insulator.

[0023] This embodiment of a sliding window or door according to the invention is very advantageous because, firstly and foremost, the production of the glazing bead support is very simple and because the adjustment of the number of channels of the thermal insulation is very limited.

[0024] Furthermore, the dimensions of the plate-shaped part of the glazing bead support ensure a good distribution of the panel support, whereas the feed-through part in the form of a protrusion has rather limited dimensions, so that the insulating properties of the thermal insulator are practically unaffected.

[0025] Preferably, the glazing bead support is also made of a synthetic material or the like, so that it does not form a thermal bridge through the profile of the sliding window or sliding door.

[0026] The invention also relates to a glazing bead support for a sliding window or door according to the invention.

[0027] In order to better illustrate the features of the present invention, the following preferred embodiments of the sliding door or sliding window and the glass bead bracket applied thereto according to the present invention are described by way of example without any limiting nature, with reference to the accompanying drawings, wherein:

[0036] Fig. 9 Shown according to Figure 7 A cross section of section IX-IX shown in FIG.

[0037] and Figure 4 similar, Fig.10 A top view showing a relevant profile of another embodiment of a sliding window according to the present invention;

[0038] Fig.11 Shows Fig.10 A perspective top view of the glass bead support indicated by arrow F11; and

[0039] Fig.12 Shown according to Fig.10 Side view of arrow F12.

[0040] Figure 1 A cross section through a known, classic sliding window 1 is shown.

[0041] Generally, such a sliding window 1 comprises a fixed frame 2 and a movable door leaf 3 in the fixed frame 2, the sliding window 1 being mounted on a wall or the like via the fixed frame 2, the movable door leaf 3 being carried by one or more roller boxes 4, the roller box 4 having a housing 5 and one or more freely rotatable rollers 6 therein, the rollers 6 being guided on rails 7 of a bottom profile 8 of the fixed frame 2.

[0042] The door leaf 3 comprises a door leaf frame 9, a panel 10 (e.g. Figure 1 The glass panel shown has double or triple glazing) is installed in the door leaf frame 9.

[0043] The door leaf frame 9 consists of an insulating composite door leaf profile 11 having a notch 12 in which a panel 10 is held by a glazing bead 13 clipped onto the door leaf profile 11 , thereby closing the edges of the panel 10 .

[0044] Typically, the door leaf profile 11 consists of half shells 14, respectively an outer shell 14a and an inner shell 14b, which are connected by one or more thermal insulators 15 in the form of insulating strips.

[0045] The panel 10 is supported by a glazing bead support 16 and aligned in the door frame by mounting blocks 17 .

[0046] Preferably, the glass bead support 16 is made of synthetic material and supported on the two half shells 14, so that the weight G of the panel 10 of the known sliding window 1 is transferred to the roller box 4 and the roller 6 through the half shells 14, as shown in FIG. Figure 1 As shown by arrows G1 and G2.

[0047] The thermal insulator 15 is made of a material that is not suitable for bearing a significant load.

[0048] Loading of the thermal insulator 15 is thus avoided since the glass bead support 16 is supported only on the half-shell 14 so that the weight G is practically completely distributed on the half-shell 14 and the sum of the parts G1 and G2 of the weight is distributed on each half-shell 14 and is practically equal to the weight G of the panel 10.

[0049] The door leaf frame 9 rests with its entire weight on the housing 5 of the roller box 4 which is fixedly connected to the half shell 14 , so that the entire weight is completely borne by the half shell of the bottom door leaf profile 11 and therefore not by the insulation 15 .

[0050] It should be understood that the half shell 14 of the bottom door leaf profile 11 must bear the entire weight of the door leaf frame 9, and it should also be understood that it is known that over time, after the application of double and triple glazing to meet increasingly stringent requirements in the field of thermal insulation, the glass panels 10 have also become increasingly heavier, which could lead to premature failure or deformation of the frame.

[0051] For the same reason, the width C of the thermal insulator 15 is continuously increased, which weakens the strength of the door leaf frame 9, while the weight of the panel increases.

[0052] The present invention provides a solution to the above-mentioned problem. Figures 2 to 12 The embodiment shown in FIG.

[0053] The solution consists in that the glazing bead support 16 comprises a feed-through portion 18 for transferring the weight G of the panel 10 or part thereof to the respectively associated housing 5 of the roller box 4 .

[0054] Of course, when multiple glass bead supports 16 are applied, the weight G is distributed on different glass bead supports 16, whereby the feed-through portion 18 of the relevant glass bead support 16 transfers a corresponding part or actually the said part of the total weight G to the relevant housing 5 of the roller 6.

[0055] According to the present invention, the feed-through portion 18 of the glass bead support 16 extends at least through a portion of the thermal insulator 15 until it reaches the housing 5 associated with the roller box 4, as shown in FIG. Figure 2 , Figure 5 and Figure 6 As shown in more detail in .

[0056] like Figure 2 As shown by the middle arrow G, the force transmission path from the panel 10 to the shell 5 of the roller box 4 is vertically directed, or actually vertically directed, and is directly transmitted to the shell 5 through the feed-through part 18, so that the half shell 14 and the insulator 15 are not significantly affected.

[0057] Figures 7 to 9 The form of the glazing bead support 16 is shown in more detail.

[0058] More specifically, the glass bead support 16 includes a plate-shaped portion 19 for supporting the edge of the panel 10 .

[0059] In this case, the feed-through portion 18 is formed by two cylindrical projections 18 a and 18 b which extend over a length L in complementary channels 20 provided in the thermal insulator 15 and are mounted perpendicularly to the underside of the plate-shaped portion 19 .

[0060] In the example shown in the figures, the sliding window 1 is provided with one or more roller boxes 4 , each of which serves as a housing 5 for a roller 6 .

[0061] For example, this Figure 3 You can see it in more detail.

[0062] The housing 5 of each roller box 4 is therefore provided with two parallel walls 5 a and 5 b.

[0063] In the case of the figures, the rollers 6 of the roller cassette 4 are always mounted in pairs in the roller modules 21 , whereby each roller 6 is individually rotatably mounted in the associated roller module 21 .

[0064] Each roller module 21 is itself tiltably mounted in the roller box 4 by means of said transverse axis 22 which is centrally mounted on the roller module 21 concerned and is attached between the walls 5 a and 5 b of the housing 5 .

[0065] The panel 10 is supported by the glass bead support 16 and is loaded by transferring a weight G through the feed-through portion 18 to the upper surface 23 of the roller box 4 .

[0066] In the example shown, the rollers 6 of the roller box 4 are also aligned according to a straight line, but according to the invention, it is not excluded to also provide pairs of rollers 6 adjacent to each other, or to apply completely different configuration examples.

[0067] exist Figures 2 to 9 In the embodiment shown, the protrusions 18a and 18b together form a feed-through portion 18 of the glass bead support 16 in the sliding window 1 and are provided with an internal pitch 24 having an internal thread, or an internal shape allowing a screw 25 to be screwed into the associated protrusion 18a or 18b.

[0068] Depending on the distance D between the protrusions 18a and 18b of the glass bead support 16, or depending on the distance D between the channels 20 in the thermal insulator 15, the housing 5 of the roller 6 (or in this case the roller box 4) is therefore provided with holes 26 at a distance D from each other.

[0069] It is not excluded that in some cases the distance D does not correspond, in which case the glass bead support 16 can be divided into two parts, each having a protrusion 18, so that in that case the weight is distributed over the two parts. Optionally, the glass bead support 16 can be provided with a weakened portion, along which the glass bead support can be more easily divided into two halves.

[0070] It is also not excluded that the glass bead support 16 has only a single protrusion 18, and each roller box 4 applies multiple glass bead supports 16 to directly transfer the weight of the panel 10 to one roller box 4. Therefore, after such a housing 5 of the roller box 4 is loaded or installed on the thermal insulator 15, the housing 5 of the roller box 4 can be attached to the glass bead support 16 by inserting screws 25 through holes 26 in the housing 5 and screwing them into the pitch 24 of the protrusions 18a and 18b.

[0071] Of course, the channels 20 and holes 26 may be drilled during installation or may be pre-realized during production of the components of the sliding window 1 .

[0072] In a preferred embodiment of the sliding window 1 according to the invention, a flexible O-ring or seal 27 has been mounted on the protrusions 18 a and 18 b of each glazing bead support 16 .

[0073] This prevents water from seeping into the lower area.

[0074] In the example discussed here, the thermal insulator 15 consists of two insulating rods 15 a and 15 b in the form of hollow profiles made of synthetic material which can be fitted fittingly or abutting against each other.

[0075] The first insulating rod 15 a is thus provided with a part 28 which can cooperate with a hook-shaped part 29 provided on one or more glass bead supports 16 to fix the glass bead support 16 on the thermal insulator 15 .

[0076] In this case, the second insulating rod 15b is provided with a longitudinally extending groove 30, which enables the roller box 4 to be mounted flush in the thermal insulator 15 at a certain height H, against the base of the associated groove 30. The groove 30 may also be omitted, for example, in which case the roller box 4 is mounted against the flat bottom side of the second insulating rod 15b.

[0077] Figures 10 to 12 More parts of another embodiment of a sliding window 1 according to the invention are shown, wherein the projections 18 a and 18 b on the glazing bead support 16 are now each provided with an inner channel 31 which extends completely through the associated projection 18 and the plate-shaped portion 19 .

[0078] On the top of the plate-shaped part 19, a non-circular groove 32 is provided, in which a nut (not shown) is mounted or can be mounted, for a bolt that can be screwed into the associated nut through the channel 31 from below, for abutting the roller box 4 against the protrusions 18a and 18b of the feed-through part 18.

[0079] The nut may be installed or pressed into the glass bead support 16 during production, or may be snapped into the groove 32 during assembly on site, for example.

[0080] The non-circular shape of the groove 32 and the corresponding non-circular shape of the nut can prevent the nut from rotating with the bolt. Alternatively, rotation can also be prevented because a nut with or without a circular shape is machined into the composite glass bead support 16 during its production.

[0081] The present invention is not limited to the embodiment of the sliding window or sliding door 1 according to the present invention and the glass bead support applied thereto, which is described by way of example and illustrated with reference to the accompanying drawings, but such a sliding window or sliding door can be implemented in various other ways without departing from the scope of the present invention.
