Description

[0001] The invention relates to a wing profile for the frame of a window or door comprising a plastic hollow profile with an outer glass stop, a glass rebate surface and an inner glass stop, which together define a glass rebate into which a filling element, in particular a glass element, can be inserted.

[0002] The invention also relates to a wing frame composed of several wing profiles.

[0003] Such a filling element is typically a glass element, e.g., an insulating glass unit. In the prior art, the inner glass rebate is generally formed by a so-called glazing bead, which is inserted from above into an upward-facing glazing bead groove located on the glass rebate surface. Individual glazing beads are attached to the glass rebate surface from the interior of each sash frame. These glazing beads thus create gaps between themselves and the inner visible surface of the hollow plastic profile, and in the corner areas also between adjacent glazing beads. Such gaps are often perceived as unsightly and tend to accumulate dirt, further detracting from the overall appearance.

[0004] Document DE 29517037 U1 of the same applicant shows such generic wing profiles.

[0005] Against this background, the invention aims to improve a sash profile of the generic type, a sash frame formed therefrom, and a method for its manufacture, in such a way that the visible frame surfaces facing the room do not exhibit any disruptive gaps and joints that arise in conventional construction due to the use of glazing beads, which are used to fix the infill elements, e.g., glass elements. The invention serves to offer a window or door with a visually appealing design that presents a seamless surface to the interior.

[0006] Document FR 3 037 985 A1 shows another wing profile.

[0007] This task is solved with a wing profile of the type mentioned above, in which the plastic hollow profile is formed by an outer wing profile and an inner wing profile which can be snapped together with it, wherein the outer wing profile has the outer glass stop and the glass rebate surface and the inner wing profile has a first upper section which forms the inner glass stop and has a second section below it which is integrally connected to the first section and which completely covers the area of ​​the outer wing profile below the first section.

[0008] The problem is further solved by a wing frame formed from such wing profiles, in which all outer wing profiles form a closed outer frame in which the outer wing profiles are welded together at their ends and all inner wing profiles form a closed inner frame in which the inner wing profiles are welded together at their ends, wherein the outer frame and inner frame can be snapped together, in particular by moving the frames towards each other.

[0009] A closed frame is preferably understood to mean that the profiles forming the frame are joined in one piece and / or by a material bond across the corners.

[0010] All directional specifications in the following description refer to the arrangement of a frame profile at the bottom of a panel element, in particular a glass panel, specifically a sash profile, which is horizontally oriented with its longitudinal direction and whose glass rebate surface faces upwards, so that the panel element can be placed on it. Of course, a sash profile can also be arranged around a panel element on all sides in a known manner. The directional specifications should then be transformed analogously.

[0011] The designation "inside" refers to the side facing the interior of the room when properly installed. The designation "outside" refers to the side facing the external environment when properly installed. The construction of the wing profile is described with reference to its cross-sectional view, where the cross-section is perpendicular to the longitudinal direction of the wing profile.

[0012] The invention preferably results in the first section covering a partial area of ​​the outer wing profile from above, or at least a part of the outer wing profile lying at least partially under the first section.

[0013] By covering the area of ​​the outer wing profile lying under the first section on the visible side of the wing profile facing the interior with the second section of the inner profile, it is preferably achieved that, through a seamless optical appearance of the inner wing profile, the wing profile as a whole has an optically flawless appearance on the visible side facing the interior, in particular without gaps and joints.

[0014] The invention thus makes it possible for the inner visible surface of the inner sash profile or of the entire sash profile to have a seamless appearance, since a separate glazing bead, as used in the prior art, is no longer necessary.

[0015] A further advantage of the invention compared to the prior art is that the inner sash profile, with its first section which effectively functions as an integrated glazing bead, retains its position after assembly on the outer sash profile, particularly by means of a locking mechanism. The contact pressure against a glass element, which is otherwise required in conventional window constructions with glazing beads, is preferably not necessary in the present invention.

[0016] The present sash design is based on a two-part sash profile, consisting of an outer sash profile and an inner sash profile. The outer sash profile is located on the weather side, and the inner sash profile is located on the room side. Both profiles are preferably made of plastic profiles, preferably PVC profiles, and manufactured using an extrusion process. Both the outer and inner sash profiles are preferably one-piece profiles, and in particular, each may also contain hollow chambers.

[0017] The outer wing profile and the inner wing profile are connected to each other in a snap-fit ​​manner, in particular by clips, and form a receiving area between them into which a filling element, e.g. a glass element, can be inserted.

[0018] The infill element is held on both sides, between the outer glass stop of the outer sash and the inner glass stop of the inner sash profile.

[0019] Preferably, the invention provides that the inner sash profile, in particular viewed perpendicular to the glass rebate surface, has a height that is at least equal to the height of the outer sash profile.

[0020] This means that the visual appearance of a frame, when viewed from inside the room, is completely defined by the inner sash profile. Preferably, the first section, viewed from the outside, particularly perpendicular to the infill element, preferably completely covers the outer glass stop of the outer sash profile. Thus, in this viewing direction, the entire outer sash profile is covered by the inner sash profile.

[0021] The invention preferably provides that the inner wing profile can be snapped onto the outer wing profile by moving it in a direction parallel to the glass rebate surface, in particular perpendicular to a filling element.

[0022] Preferably, the inner wing profile is attached to the outer wing profile with at least one locking projection, preferably with at least two locking projections, or at least can be attached in a locking manner.

[0023] For example, it can be provided that at least one locking projection, preferably two locking projections, extends from the second section towards the area of ​​the outer wing profile lying below the first section.

[0024] A locking projection, especially if it is the only one, can include a hollow chamber or be designed as a web without a hollow chamber.

[0025] Preferably, the second section is equipped with at least one hollow chamber, preferably with two hollow chambers arranged one above the other, which in particular leads to a higher stiffness of the second section.

[0026] Preferably, in the invention, the outer wing profile has a receiving groove on its side facing the second section, open in the direction of the second section, into which a locking projection can engage in a locking manner, which projects from the second section, in particular in its upper region, and / or the outer wing profile has a recess open in the direction of the second section and downwards, into which a locking projection can engage in a locking manner, which projects from the second section, in particular at its lower end.

[0027] It is further preferred that a locking projection is arranged on the underside of the first section of the inner wing profile, projecting towards the glass rebate surface of the outer wing profile, in particular being inclined in its extension towards the second section, which can be connected in a locking manner to a locking lug projecting from the glass rebate surface, in particular being inclined in its extension towards the outer glass stop.

[0028] In the design, it is particularly preferred that the locking projection on the first section forms an extension of the web on the first section pointing towards the glass stop, in particular via which the first section can be indirectly attached to a filling element via a sealing element.

[0029] Preferably to achieve improved stiffening, the invention may provide that the inner wing profile in the first section has at least one hollow chamber, in particular the one furthest towards the glass stop, which is diagonally traversed by a strut.

[0030] The invention provides that the inner wing profile, in addition to the first and second sections, has a third section located below the second section, which forms a wing overlap. In this embodiment, the first, second, and third sections are all formed integrally.

[0031] According to the invention, the third section, or the wing overlap formed therewith, has a fastening groove for receiving a sealing element, preferably with which the wing overlap can be sealed against a frame profile or a threshold profile.

[0032] According to the invention, the third section extends into an area below the underside of the outer wing profile, which includes a fitting groove for receiving fitting elements.

[0033] According to the invention, the third section has a hollow chamber whose cross-section increases downwards and which has its maximum cross-section in the area behind a fastening groove for receiving a sealing element.

[0034] All sections of the inner wing profile can preferably have at least substantially the same height, or the second section can have the greatest height of all sections. In particular, the first section can have the smallest height.

[0035] According to the invention, the inner wing profile thus consists of at least two, preferably even three sections.

[0036] The inner glass stop is functionally integrated into the first section and is an integral part of the inner sash profile, fulfilling the function of a glazing bead that would otherwise be used at this point. The glass stop, or first section, can be manufactured in any required width.

[0037] Preferably, the glass stop or the first section contacts the outer sash profile at only one point (relative to the cross-section) or along a line on the longitudinal extent of the profiles, namely where the locking projection on the first section of the inner sash profile interacts with the locking lug on the glass rebate surface of the outer sash profile. This locking connection creates a secure connection between the inner sash profile and the outer sash profile, preferably without the need for additional fasteners.

[0038] The second section forms a section, preferably a middle section, which extends on the visible side over that section of the

[0039] The outer sash profile extends below the glazing rebate surface of the outer sash profile. The second section of the inner sash profile forms an area through which the inner sash profile can still be attached to the outer sash profile, in particular by line and surface contact.

[0040] The inner wing profile is preferably provided in the second section with two locking projections that extend from the second section towards the outer profile and can engage in corresponding locking recesses on the outer wing profile. The locking projections can have different geometric shapes.

[0041] A locking projection preferably engages in a receiving groove of the outer wing profile, in particular which (viewed in section) is only open in the direction towards the interior of the space, and in particular is therefore only open in the horizontal direction.

[0042] A second locking projection preferably engages in a locking recess on the outer profile, which is open both horizontally and vertically downwards towards the interior. This recess can abut a wall that borders the outer profile at the bottom.

[0043] A preferably provided third section connects to section II at the bottom and forms a stop area with which a sash frame profile can abut a frame profile.

[0044] All sections I - III preferably form a uniform visible surface facing the interior, as a seamless optical unit without grooves, joints or edges. The inner sash profile surrounds the outer sash profile and rests against it on the interior side, either at points or along lines, and partially in full surface contact.

[0045] The invention preferably provides that at least one of the following types of contact is formed between the inner wing profile and the outer wing profile: For example, the first section has line contact with the outer wing profile along the longitudinal direction of the profiles, particularly in the area of ​​interaction between the locking projection and the locking lug. For example, the second section has line and surface contact with the outer wing profile along the longitudinal direction of the profiles, particularly line contact at the end of the at least one locking projection, and particularly surface contact between two locking projections. For example, the third section is contactless with the outer wing profile. These types of contact can be provided individually or in any combination.

[0046] Besides the stop function of the sash profile, the holding function of the infill element, especially the glass element, is important. The sometimes large and heavy glass elements must be securely held in the window frame.

[0047] The invention is characterized in that the inner sash profile forms a statically stable unit with the outer sash profile through the interlocking or clip connections. Compared to conventional sash constructions that are provided with a glazing bead, the presented invention preferably does not require any contact pressure on the infill element / glass element. On the weather side, the outer sash profile can preferably be clad with a weather-resistant metal cover, in particular an aluminum cover.

[0048] A method for manufacturing a sash frame filled with a filling element comprises the following steps, where at least a) and b) can be in any order: a) Joining outer sash profiles to an outer frame by means of corner welding at the mitered ends of the outer sash profiles, b) Joining inner sash profiles to an inner frame by means of corner welding at the mitered ends of the inner sash profiles, c) Applying a sealing strip (60) to the surface of the inner glass stop on the first section facing a filling element, d) Inserting a filling element, in particular a glass element, into the preferably horizontal outer frame, in particular using glazing blocks, e) Connecting the outer frame and inner frame, in particular by moving the inner frame towards the outer frame and thereby interlocking the frames with each other.

[0049] Preferably, the injection of a bead of adhesive into the gap between the glass rebate surface and the filling element or glass element is also provided.

[0050] It is preferably important to note that before the corner welding of the inner sash frame, the locking protrusion in the corner areas must be milled away to avoid an unwanted excess of plastic in the welding area.

[0051] The outer frame and inner frame can only be joined in a parallel plane. To do this, the largest of the locking tabs is inserted into the receiving groove of the outer frame's outer sash profile and pressed in along the groove. Since plastic has a basic elasticity, the locking tab is drawn into the receiving groove under slight pressure.

[0052] The corresponding locking projections and recesses or lugs of the inner and outer wing profiles engage when the locking projection of the inner wing profile interlocks with the leading edge of the locking lug of the outer wing profile during the forward movement of the joining process.

[0053] In this way, the inner and outer sash frames are precisely and firmly connected to each other, and the glass element is simultaneously clamped and fixed.

[0054] The method described above is not part of the claimed invention.

[0055] The invention is explained in more detail below with reference to the drawings. Fig. 1 shows a sectional view of a window with a two-part sash profile and frame profile in the closed position. Fig. 2 shows the two-part sash frame with aluminum cover. Figure 1 Fig. 3 shows only the inner sash profile in section. Fig. 4 shows only the outer sash profile with aluminum trim in section. Fig. 5 shows a two-part sash frame with a bottom sill. Fig. 6 shows a variant of a two-part sash frame with only two sections.

[0056] The Figure 1Figure 1 shows a window 100 with a two-part sash profile and frame profile 10 in the closed position as a sectional view. The two-part sash profile implements the invention and is composed of the outer sash profile 20 and the inner sash profile 30. The outer sash profile 20 is located on the weather side and is preferably additionally clad with an aluminum cover 40. This cover can also be omitted.

[0057] A glass element 50 is arranged and held as a filling element between the outer glass stop 23 and the inner glass stop 33. The glass element 50 is preferably supported on a glass block 70 and further preferably bonded in the glass rebate surface 21. The inner sash profile 30 surrounds the outer sash profile 20 and is designed at its upper free end as a glass stop 33, which is provided with a sealing strip 60 on the side facing the glass element 50 and holds the glass element 50 firmly in the sash frame. The glass stop 33 is formed on or by a first upper section of the inner sash profile 30.

[0058] The other lower free end of the inner sash profile 30 is shaped as a sash overlap 31, which acts as a stop against the frame profile 10. This is formed in a third section of the inner sash profile 30. The first and third sections are connected to each other by a second section.

[0059] The Figure 2Figure 1 depicts the two-part sash frame with a preferred aluminum cover 40. The outer sash profile 20 and the inner sash profile 30 are interlocked or clipped together, forming a receiving area between them into which a glass element 50 can be inserted.

[0060] The inner glass stop 33 as the first section I,The inner glazing bead 33 is an integral part of the inner sash profile 30 and functions as a glazing bead, which is otherwise used at this location. The inner glazing bead 33 can be manufactured in any required width and preferably contacts the outer sash profile 20 at only one point (viewed in section), or along a single line, namely where the locking projection 34 of the inner sash profile 30 engages with the locking lug 24 of the outer sash profile 20. This locking connection forms a secure connection between the inner sash profile 30 and the outer sash profile 20, preferably without the need for additional fasteners.

[0061] The second section II forms the central section, which extends over the outer wing profile 20 on the side facing the interior and completely covers it. The second section II of the inner wing profile 30 preferably connects to the outer wing profile 20 via point, line, or surface contact. In the second section II, the inner wing profile 30 is provided on the side facing the outer wing profile 20 with a first locking projection 34 and a second locking projection 36, which can be locked to, or are locked into, the outer wing profile. The locking projection 35 engages in the receiving groove 25.

[0062] In Figure 3 The isolated inner wing profile 30 is shown, as are the locking projections 34 and 36, and the hook-shaped locking projection 35. The geometric design of the locking projection 35 results in two opposing contact points. In the assembled view according to Figure 2The tip of the locking projection 35 rests against the upper wall of the receiving groove 25 and the base of the locking projection 35 is supported in the entrance area of ​​the receiving groove 25, which ensures a tight fit.

[0063] A second locking projection 36 engages in a recess 36 of the outer wing profile 20 and additionally positions and secures the position of the outer wing profile 20 relative to the inner wing profile 30.

[0064] The third section III is shaped as a wing overlap 31 and serves as a stop for the frame profile 10.

[0065] The height of the visible surface of the inner wing profile 30 from the interior of the room corresponds essentially or exactly to the height of all three sections I, II, III.

[0066] Figure 4The figure shows the outer sash profile 20 with the preferred aluminum cover 40 in section. The glass rebate surface 21 and the underside or sash hardware surface 22 are parallel to each other. The locking lug 24 has a chamfer 24' which facilitates the clipping on of the inner sash profile 30. The locking lug 24 can therefore also be understood as being inclined in the direction of the outer glass stop 23.

[0067] Likewise, the receiving groove 25 has a leading-edge slope 25' which also facilitates the locking of the locking projection 35 when joining the inner wing profile 30 with the outer wing profile 20.

[0068] The Figure 5 This represents a two-part sash frame in combination with an 80 mm threshold. Naturally, the two-part sash frame can also be used in this variation.

[0069] Figure 6This shows another variant of a two-part sash frame. The inner sash profile 30 here only comprises the first and second sections I and II.

[0070] The sash overlap is omitted, for example, because it is a window without a tilt function. The main locking mechanism is also achieved by means of the locking projection 35, which, although modified, is comparable in function to the prescribed one. It has two opposing support points in the receiving groove 25. Furthermore, it includes a hollow chamber.

[0071] Unlike the explanations following the Figure 1 - 5 In this embodiment, the fixing of the inner wing profile 30 in the area of ​​the inner glass stop 33 is given by the contact pressure against the glass element 50 and not by its own locking mechanism. Reference symbol list
