The invention also relates to a sash frame made of such sash profiles (20, 30), a window (100) or a door with such a sash frame and a method for producing a sash frame filled with a filling element.

Description

The invention relates to a sash profile for the frame of a window or a door comprising a hollow plastic 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.

The invention also relates to a casement frame which is composed of several casement profiles and to a method for producing a casement frame for a window or door which is filled with a filling element. Such a filling element is usually a glass element, e.g. an insulating glass pane.

In the state of the art, the inner glass stop is generally formed by a so-called glazing bead, which can be inserted from above into a glazing bead groove that is open at the top and is arranged on the glazing rebate surface. For this purpose, individual glazing beads are placed on the glazing rebate surface on each side of a casement from the inside of the room. Such glazing beads thus form gaps between themselves and the inner visible surface of the hollow plastic profile and, in the corner areas, also between the adjacent glazing beads.

Such gaps are often perceived as visually unattractive and tend to accumulate dirt, which further worsens the negative appearance.

The document DE 29517037 U1 The same applicant shows such generic wing profiles.

Against this background, the invention is based on the task of improving a sash profile of the generic type, a sash frame to be formed from it and a method for its production in such a way that the visible frame surfaces on the room side do not have any annoying gaps and joints that arise in conventional construction through the use of glazing beads that are used to fix the filling elements, e.g. glass elements. The invention serves to offer a window or door with a visually appealing design that presents a seamless visible surface to the interior of the room.

This object is achieved with a sash profile of the type mentioned at the outset, in which the plastic hollow profile is formed by an outer sash profile and an inner sash profile that can be connected to it in a locking manner, wherein the outer sash profile has the outer glass stop and the glass rebate surface and the inner sash profile has a first upper section that forms the inner glass stop and has a second section underneath that is integrally connected to the first section and that completely covers the area of the outer sash profile that lies below/underneath the first section.

The object is further achieved by a sash frame formed from such sash profiles, in which all outer sash profiles form a closed outer frame in which the outer sash profiles are welded together at their ends and all inner sash profiles form a closed inner frame in which the inner sash profiles are welded together at their ends, wherein the outer frame and inner frame can be fastened to one another in a locking manner, in particular by moving the frames towards one another.

A closed frame is preferably understood to mean that the profiles forming the frame are integrally and/or firmly connected across the corners.

All directional information in the following description refers to the arrangement of a frame profile at the bottom of a filling element, in particular a glass element, in particular a sash profile which is aligned horizontally with its longitudinal extension and whose glass rebate surface faces upwards so that the filling element can be placed on it. Of course, a sash profile can be arranged on all sides around a filling element in a known manner. The directional information must then be transformed analogously.

The direction indication "inside" refers to the side that faces the interior of the room when installed as intended. The direction indication "outside" refers to the side that faces the outside environment when installed as intended. The design of the sash profile is described with reference to its cross-sectional view, with the cross-section being perpendicular to the longitudinal direction of the sash profile.

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 being located at least partially under the first section.

By covering the area of the outer sash profile lying under the first section on the visible side of the sash profile facing the interior of the room with the second section of the inner profile, it is preferably achieved that, due to a seamless optical appearance of the inner sash profile, the sash profile as a whole has a visually perfect appearance on the visible side facing the interior of the room, in particular without gaps and joints.

The invention therefore makes it possible for the inner visible surface of the inner sash profile or the entire sash profile to have a seamless appearance, since a separate glass strip, as used in the state of the art, is no longer required.

An advantage of the invention over the cited prior art is that the inner sash profile with the first section, which in fact has the function of an integrated glazing bead, maintains its position after assembly on the outer sash profile, in particular by locking. The otherwise required contact pressure on a glass element, as is usual with conventional window constructions with glazing bead, is preferably not required with the present invention.

The present wing construction is based on a two-part wing profile, which consists of an outer wing profile and an inner wing profile. The outer wing profile is on the weather side and the inner wing profile is on the room side. Both profiles are preferably made of plastic profiles, preferably PVC profiles, and are produced using an extrusion process. The outer and inner wing profiles are preferably one-piece profiles, in particular each with hollow chambers.

The outer wing profile and the inner wing profile are connected to each other in a locking manner, in particular clipped, and form a receiving area between them into which a filling element, e.g. a glass element, can be inserted.

The filling 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.

The invention preferably provides that the inner sash profile, in particular viewed perpendicular to the glazing rebate surface, has a construction height which corresponds at least to the construction height of the outer sash profile.

This means that the visual appearance of a frame when viewed from the inside of the room is completely defined by the inner sash profile. Preferably It is provided that in the outward viewing direction, in particular perpendicular to the filling element, the first section preferably completely covers the outer glass stop of the outer sash profile. Overall, the entire outer sash profile is therefore covered by the inner sash profile in this viewing direction.

The invention preferably provides that the inner sash profile can be fastened to the outer sash profile in a locking manner by movement in a direction parallel to the glazing rebate surface, in particular which is perpendicular to a filling element, towards the outer sash profile.

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

For example, it can be provided that the at least one locking projection, preferably two locking projections, protrude from the second section in the direction of the region of the outer wing profile located below the first section.

A locking projection can, particularly if it is the only one, comprise a hollow chamber or be designed as a web without a hollow chamber.

Preferably, the second section is equipped with at least one hollow chamber, preferably with two hollow chambers lying one above the other, in particular which leads to a higher rigidity of the second section.

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

Further preferably, a locking projection projecting in the direction of the glass rebate surface of the outer sash profile is arranged on the lower surface of the first section of the inner sash profile, in particular which is inclined in its extension in the direction of the second section, which can be connected in a locking manner to a locking lug projecting from the glass rebate surface, in particular which is inclined in its extension in the direction of the outer glass stop.

In this case, it is particularly preferably provided in the construction 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 applied indirectly to a filling element via a sealing element.

Preferably, in order to achieve improved stiffening, the invention can provide that the inner sash profile in the first section has at least one hollow chamber, in particular the one located furthest in the direction of the glass stop, which is diagonally traversed by a strut.

A preferred development provides that the inner wing profile has, in addition to the first section and second section, 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 with one another.

The third section, or the sash overlap formed thereby, preferably has a fastening groove for receiving a sealing element, preferably with which the sash overlap can be sealed against a frame profile or a threshold profile.

The third section preferably extends into an area below the lower surface of the outer wing profile, in particular which comprises a fitting groove for receiving fitting elements.

The third section preferably further comprises a hollow chamber whose cross-section increases downwards, in particular which has a maximum cross-section in the region behind a fastening groove for receiving a sealing element.

All sections of the inner wing profile can preferably have at least substantially the same height or it is provided that the second section has the greatest height of all sections. In particular, the first section can have the smallest height.

According to the invention, the inner wing profile is therefore composed of at least two, preferably even three sections.

The inner glass stop is functionally implemented in the first section and is an integral part of the inner sash profile and takes on the function of a glazing bead that is otherwise used in this place. The glass stop or first section can be designed in any required width.

Preferably, the glass stop or the first section contacts the outer sash profile at only one point (in relation to the cross section) or a line along the longitudinal extension 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. Via this locking connection, the inner sash profile and the outer sash profile form a firm connection, preferably one that does not require any additional fastening means.

The second section forms a section, preferably a middle section, which extends on the visible side over that section of the outer sash profile, which lies under the glass rebate surface of the outer sash profile. The second section of the inner sash profile forms an area via which the inner sash profile can still be fastened to the outer sash profile, in particular can be fastened with line and surface contact.

The inner wing profile is preferably provided with two locking projections in the second section, which project 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.

A locking projection preferably engages in a receiving groove of the outer sash profile, in particular which (viewed in section) is only open in the direction towards the interior of the room, in particular is thus only open in the horizontal direction.

A second locking projection preferably engages in a locking recess on the outer profile, which is open both towards the interior of the room, i.e. horizontally and vertically downwards. This recess can be adjacent to a wall that limits the outer profile at the bottom.

A preferably provided third section adjoins section II at the bottom and forms a stop area with which a sash frame profile can be attached to a frame profile.

All sections I - III form a uniform visible surface, preferably towards the interior of the room, 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 inside of the room, in a point or line shape and partially in contact with the surface.

The invention can preferably provide 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 a line contact with the outer wing profile along the longitudinal direction of the profiles, in particular in the area of interaction between the locking projection and locking lug. For example, the second section has line and surface contact with the outer wing profile along the longitudinal direction of the profiles, in particular line contact at the end of the at least one locking projection, in particular surface contact between two locking projections. For example, the third section is contact-free with the outer wing profile. These types of contact can be provided individually or in any combination.

In addition to the stop function of the sash profile, the holding function of the filling element, especially the glass element, is important. The sometimes large and heavy glass elements must be held securely in the window frame.

The invention is characterized by the fact that the inner sash profile forms a statically stable unit with the outer sash profile through the locking or clip connections. In contrast to conventional sash constructions that are provided with a glazing bead, the invention presented preferably does not require any contact pressure on the filling element / glass element.

On the weather side, the outer sash profile can preferably be covered with a weather-resistant metal cover, in particular an aluminum cover.

A method according to the invention for producing a sash frame filled with a filling element comprises the following steps, whereby at least a) and b) can be in any order:

1. a) Joining outer wing profiles to an outer frame by means of corner welding at the mitred ends of the outer wing profiles,
2. b) Joining inner sash profiles to an inner frame by means of corner welding at the mitred ends of the inner sash profiles,
3. c) applying a sealing tape (60) to the surface of the inner glass stop on the first section facing a filling element,
4. d) Inserting a filling element, in particular a glass element, into the preferably horizontal outer frame, in particular using blocking elements,
5. e) Connecting the outer frame and the inner frame, in particular by moving the inner frame towards the outer frame and thereby locking the frames together.

Preferably, an adhesive bead is also provided for injecting into the gap between the glazing rebate surface and the filling element or glass element.

It is preferable to note that before welding the corners of the inner sash frame, the locking projection in the corner areas must be milled away in order to avoid unwanted excess plastic in the welding area.

The outer frame can only be joined to the inner frame in a plane-parallel manner. To do this, the largest of the locking projections is pushed into the receiving groove of the outer wing profile of the outer frame and pressed along the groove. Since plastic has a basic elasticity, the locking projection pulls into the receiving groove under slight pressure.

The corresponding locking projections and recesses or lugs of the inner and outer wing profiles engage in that the locking projection of the inner wing profile locks into each other via the run-on slope of the locking lug of the outer wing profile in the forward movement of the joining process.

In this way, the inner and outer sash frames are firmly connected to one another and the glass element is clamped and fixed at the same time.

The Figure 1 shows a window 100 with a two-part sash profile and a frame profile 10 in a 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 arranged on the weather side and is preferably additionally covered with an aluminum cover 40. This can also be omitted.

As a filling element, a glass element 50 is arranged and held between the outer glass stop 23 and the inner glass stop 33. The glass element 50 is preferably mounted on a glass block 70 and more preferably glued 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.

The other lower free end of the inner sash profile 30 is shaped as a sash overlap 31, which acts as a stop on 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 one another by a second section.

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

The inner glass stop 33 as the first section I is an integral part of the inner sash profile 30 and takes on the function of a glazing bead that is otherwise used at this point. The inner glass stop 33 can be designed in any required width and preferably contacts the outer sash profile 20 at only one point (viewed in section) or a line, namely where the locking projection 34 of the inner sash profile 30 interacts with the locking lug 24 of the outer sash profile 20. Via this locking connection, the inner sash profile 30 and the outer sash profile 20 form a firm connection that preferably does not require any additional fastening means.

The second section II forms the middle section, which extends over the side of the outer wing profile 20 facing the interior of the room and completely covers it. The second section II of the inner wing profile 30 is preferably connected to the outer wing profile 20 by point, line and surface contact. The inner wing profile 30 is provided in the second section II 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 or are locked to the outer wing profile. The locking projection 35 engages in the receiving groove 25.

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

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 to the inner wing profile 30.

The third section III is formed as a sash overlap 31 and serves as a stop for the frame profile 10.

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

Figure 4 shows the outer sash profile 20 with the preferred aluminum cover 40 in section. The glass rebate surface 21 and the bottom surface or sash fitting surface 22 are parallel to one another. The locking lug 24 has a starting bevel 24', which makes it easier to clip on 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.

Likewise, the receiving groove 25 has a run-on slope 25', which also facilitates the engagement of the locking projection 35 when the inner wing profile 30 is joined to the outer wing profile 20.

The Figure 5 represents a two-part sash frame in combination with a threshold 80. Of course, the two-part sash frame can also be used in this variation.

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

The sash overlap is omitted, e.g. because it is a window without a tilt function. The main locking is also implemented using the locking projection 35, which is modified but comparable in its function to the prescribed one. It has two opposing support points in the receiving groove 25. It also includes a hollow chamber.

Unlike the statements made after the Figures 1 - 5 In this embodiment, the fixing of the inner sash profile 30 in the area of the inner glass stop 33 is provided by the contact pressure on the glass element 50 and not by a separate locking mechanism.
