Abstract

The invention relates to a method for fastening a profile, in particular a transom, to a rod for producing a window frame, wherein the front sides of overlaps are milled off and connected to one another. The invention further relates to an associated window frame or partial window frame and a device for producing a window frame or partial window frame.

Description

The invention relates to a method for fastening a profile, in particular a transom, to a bar, a window frame or a window part frame and a device for producing a window frame or window part frame.

Window frames are typically used to be inserted into a building opening and attach windows thereto, window frames also typically serving the function of providing a defined stop for the windows. When closed, these usually close tightly with the window frame. For this purpose, a window frame can in particular have flaps, which can be formed on a bar or a profile.

A profile which is typically arranged vertically in a window frame when installed is also referred to as an impost. Windows typically slam on this too. While most window frames are designed so that two windows can be opened in the same direction, in some countries there is a widespread use of designs in which the windows can be opened in different directions. A fighter for such an execution is also referred to as an alternating fighter.

It is an object of the invention to provide a method for attaching a profile, in particular a fighter, to a staff which is improved compared to known designs in particular in that an alternate fighter can be easily attached. Furthermore, the objects of the invention are to provide an associated window frame or window sub-frame and an associated device for producing a window frame or a window sub-frame. According to the invention, this is achieved by a method, a window frame or partial window frame and a device according to the respective main claims. Advantageous configurations are claimed, for example, in the dependent claims.

• Bereitstellen des Profils, wobei das Profil sich entlang einer zweiten Längsrichtung erstreckt, wobei das Profil einen dritten Überschlag und einen vierten Überschlag aufweist, welche sich von diagonal gegenüberliegenden Längskanten des Profils in zueinander entgegengesetzte Richtungen erstrecken,
• Abschrägen von Stirnseiten des ersten Überschlags und des zweiten Überschlags, so dass der erste Überschlag und der zweite Überschlag ihre größte Erstreckung am Übergang zur Oberfläche haben,
• Abschrägen des dritten Überschlags und des vierten Überschlags an einem Längsende des Profils, so dass der dritte Überschlag und der vierte Überschlag am Längsende ihre größte Erstreckung haben,
• Zusammenführen des Profils mit dem Stab, so dass die zweite Längsrichtung winklig, bevorzugt rechtwinklig, zur ersten Längsrichtung ist.

The invention relates to a method for attaching a profile, in particular a transom, to a bar for producing a window frame with overlaps on the outside and inside of the window frame. The procedure has the following steps:

• Providing the rod, wherein the rod extends along a first longitudinal direction and has at least one surface from which a first flap and a second flap extend in the same direction, wherein along the first longitudinal direction up to a connection area the first flap is attached to a is arranged on the first long side of the surface and from the connection area the second flap is arranged on a second long side of the surface which is opposite the first long side,
• providing the profile, the profile extending along a second longitudinal direction, the profile having a third fold and a fourth fold extending from diagonally opposite longitudinal edges of the profile in mutually opposite directions,
• chamfering end faces of the first fold and the second fold, so that the first fold and the second fold have their greatest extension at the transition to the surface,
• beveling the third rollover and the fourth rollover at a longitudinal end of the profile, so that the third rollover and the fourth rollover have their greatest extent at the longitudinal end,
• Bringing the profile together with the bar so that the second longitudinal direction is at an angle, preferably at right angles, to the first longitudinal direction.

Through these process steps, the profile and the bar can be prepared for the connection in an advantageous manner, since the flaps are beveled in such a way that they ideally match one another.

The profile can in particular be a transom, which is typically oriented vertically in a finished window frame when installed. In particular, the bar can be a part of a window frame which is horizontally aligned in a finished window frame. In the installed state, it can be arranged, for example, at the top or bottom. An outside can in particular be a side of the window frame which faces the surroundings of a building in the installed state. An inside can in particular be a side of the window frame which faces an interior of the building in the installed state.

An extension of the flaps in the same direction can in particular be understood to mean that, viewed from the surface, they extend to the same side with respect to a plane of the surface. However, the first flap and the second flap are arranged along different longitudinal sides of the surface, it being possible for these longitudinal sides to extend, for example, along a longitudinal extent of the rod. Thus, the flaps are typically spaced apart in a direction transverse to the length of the rod.

The extension in opposite directions, which applies to the third flap and the fourth flap, can mean in particular that they extend in different directions when viewed from one plane. The profile can in particular have an at least essentially cuboid cross-section, with the third and the fourth flap typically being able to be arranged on diagonally opposite edges of this cuboid.

The respective largest extension of the first flap and the second flap at the transition to the surface can mean in particular that a cross section seen along a longitudinal extension of the respective flap, which can in particular be parallel to the longitudinal extension of the rod, continuously decreases towards the transition to the surface. The same applies to the third and the fourth rollover with regard to their extension towards the longitudinal end.

• Verbinden, insbesondere Verkleben oder Verschweißen, des Profils mit dem Stab am Verbindungsbereich derart, dass nach dem Verbinden der dritte Überschlag den ersten Überschlag außenseitig zumindest partiell überdeckt und der vierte Überschlag den zweiten Überschlag außenseitig zumindest partiell überdeckt.

According to a possible procedure, the method also has the following step:

• Connecting, in particular gluing or welding, the profile to the bar in the connection area in such a way that after the connection, the third flap at least partially covers the first flap on the outside and the fourth flap at least partially covers the second flap on the outside.

Such a procedure can in particular result in a partial covering of the flaps being provided, as a result of which the flaps can be easily attached to one another and form a shapely transition. In particular, a visible joint can be formed at an angle midway between the profile and the bar.

• Verbinden, insbesondere Verkleben oder Verschweißen, des Profils mit dem Stab am Verbindungsbereich derart, dass nach dem Verbinden eine Stirnseite des dritten Überschlags eine Stirnseite des ersten Überschlags überdeckt und eine Stirnseite des vierten Überschlags eine Stirnseite des zweiten Überschlags überdeckt.

According to a possible procedure, the method also has the following step:

• Connecting, in particular gluing or welding, the profile to the bar at the connection area in such a way that after the connection, a front side of the third flap covers a front side of the first flap and a front side of the fourth flap covers a front side of the second flap.

Such a process management makes it possible in particular to dispense with overlapping of the flaps, with the flaps each adjoining one another at their end faces. This enables a simple design, in which case the end faces in particular can adjoin one another along an angle bisecting line between the bar and profile, which corresponds, for example, to a mitred design.

It should be understood that the two procedures just described with regard to the connection can be considered in particular as alternatives.

According to a preferred embodiment, respective longitudinal cavities are formed in the first flap and in the second flap. In particular, these can be closed at the end by the profile after the connection. Such cavities can simplify manufacture and reduce weight. Closing with the profile prevents air or moisture from penetrating into the window when it is open and possibly causing problems there.

According to one embodiment, the third flap is beveled in such a way that, after the connection, it is complementary to the first flap and partially covers the first flap on the outside. According to a further preferred embodiment, the fourth flap is beveled in such a way that it is complementary to the second flap after the connection and partially covers the second flap on the outside. As a result, the respective overlap can already be prepared by the bevel.

According to an alternative embodiment, the third flap is bevelled so that its face is complementary to the face of the first flap. Furthermore, the fourth flap can be beveled so that its face is complementary to the face of the second flap. As a result, the end faces can directly adjoin one another so that, for example, overlapping can be dispensed with.

It should be mentioned that overlapping and the adjoining of end faces can also be combined, in which case, for example, an area lying further outwards in a corner can overlap and end faces can adjoin one another directly in an area lying further inwards.

According to one embodiment, the first flap is formed along the first longitudinal direction up to the beginning of the second flap. In particular, this can relate to the transitions to the surface already mentioned. This enables the flaps to be directly adjacent, apart from the fact that they are arranged on different longitudinal sides.

According to one embodiment, an intermediate area extending in the longitudinal direction of the rod is formed between the first flap and the second flap. As a result, the flaps can be spaced apart from one another in the longitudinal direction. This can also relate in particular to the respective transitions to the surface.

• Ausfräsen einer Einkerbung in dem Stab zwischen dem ersten Überschlag und dem zweiten Überschlag, so dass eine Längsrichtung der Einkerbung zwischen dem ersten Überschlag und dem zweiten Überschlag verläuft, und
• beidseitiges Abfräsen des Längsendes des Profils, welches mit dem Stab verbunden wird, zwischen dem dritten Überschlag und dem vierten Überschlag, so dass beidseitig Abschrägungen zwischen dem dritten Überschlag und dem vierten Überschlag verlaufen.

According to one embodiment, the method also has the following steps:

• milling an indentation in the bar between the first rim and the second rim such that a longitudinal direction of the indentation is between the first rim and the second rim, and
• Milling on both sides of the longitudinal end of the profile, which is connected to the rod, between the third flap and the fourth flap, so that bevels run on both sides between the third flap and the fourth flap.

Such a procedure can further simplify the attachment of rod and profile to one another, since the notch can specify the position of the profile and can also fix it. In addition, production can be simplified, since corresponding bevels can typically be easily produced using milling tools.

In particular, the notch can be at least essentially or also completely complementary to the bevels. As a result, the bevel and the notch can adjoin one another in an advantageous manner and define the mutual position.

In particular, the notch can extend partially into the first flap and/or the second flap. In particular, the bevels can extend partially into the third flap and/or the fourth flap. It has been shown that preferred geometric conditions can be achieved in this way.

In particular, areas of the end faces of the first flap and the second flap, which are covered by the end faces of the third flap and/or the fourth flap, can be milled using a separate milling tool, leaving a respective cheek adjoining the flap, which has the notch on the side limited. This allows the chamfers to be executed up to the respective overlaps even in the case of a desired lateral delimitation of the notch by cheeks, whereby a smaller or thinner milling tool can be used for this purpose than for other designs of the chamfers. As a result, the cheeks can be left standing in a defined manner.

The milled longitudinal end can engage in the notch, in particular when connecting. As a result, additional stability can be achieved and the positions relative to one another can be precisely defined.

In particular, the profile can be welded to the bar using a V-shaped or Y-shaped cross-section heating mirror. This allows a particularly good adaptation to the geometric conditions, since the notch typically has a V-shape, particularly when using the notch and the bevels already described above. If the rod is already in its solid final state when the profile is connected to the rod, a V-shaped heating mirror in particular can be used here. If the connection of two bar parts, as described below, and the connection of the bar to the profile are to take place in one work step, the use of a heating mirror with a Y-shaped cross section is particularly advisable. Such heating mirrors can advantageously be adapted to the respective geometry.

• teilweises Abfräsen seitlicher Wangen des Profils am Längsende, welches mit dem Stab verbunden wird.

According to a possible procedure, the method also has the following step:

• Partial milling of the lateral cheeks of the profile at the longitudinal end, which is connected to the bar.

By milling off lateral cheeks in this way, the profile can be formed in such a way that its cheeks fit together in the best possible way with corresponding cheeks of the bar. In this case, cheeks can in particular delimit sides, in particular delimiting essentially or also completely flatly, which in the installed state face an inner side or an outer side.

In particular, the cheeks can be milled so far that, after the connection, they lie flat on the surface of the bar and/or on a respective extension of the surface outside of the first and second flaps. In typical applications, this allows a particularly elegant design.

The third flap and the fourth flap can be bevelled in a round or curved manner, in particular at the longitudinal end. This allows an advantageous adaptation to the first rollover and the second rollover, so that they can overlap in the best possible way and can advantageously lie directly against one another.

In particular, the first flap and the third flap can be provided for the first window. Furthermore, in particular the second flap and the fourth flap can be provided for the second window. This allows the attachment of two windows, which can be opened in particular in different directions. This corresponds to the typical design with alternating fighters.

• Bereitstellen eines Ausgangsstabs mit einem durchgehenden Überschlag,
• Durchtrennen des Ausgangsstabs quer zur Längsrichtung des Ausgangsstabs, so dass ein erstes Stabteil und ein zweites Stabteil entstehen,
• Drehen zumindest des zweiten Stabteils und Zusammenführen mit dem ersten Stabteil, so dass die Oberfläche durchgehend entsteht, und
• Verbinden des ersten Stabteils mit dem zweiten Stabteil.

The provision of the staff can include the following steps in particular:

• providing a starting rod with a continuous rollover,
• Cutting through the starting bar transversely to the longitudinal direction of the starting bar, so that a first bar part and a second bar part are created,
• Rotating at least the second rod part and bringing it together with the first rod part so that the surface is continuous, and
• Connecting the first rod part to the second rod part.

With such a method, continuous production without geometric variation can be used to produce the starting rod. By simply cutting through and reconnecting, the shape of the rod that is required for the process described here can be achieved. In this way, in particular, the first flap and the second flap can be formed from the continuous flap. These can then be milled off at their ends to achieve the desired shape.

The starting bar can be severed, in particular, transversely to a longitudinal extent of the starting bar. However, other angles can also be used.

In particular, the first bar part can be connected to the second bar part in one work step with the connection of the profile to the bar using a welding mirror with a Y-shaped cross section. As a result, one process step can suffice to connect the two rod parts and the profile to one another. Reference is made to the above statements on a welding mirror with a Y-shaped cross section.

The invention also relates to a window frame or window frame part, at least consisting of a longitudinal bar and a profile adjoining it at an angle, not at the corners of the bar, in a connection area of the bar, the bar extending along a first longitudinal direction and at least one has a surface from which a first flap and a second flap extend in the same direction, wherein along the first longitudinal direction up to a connection area the first flap is arranged on a first longitudinal side of the surface and from the connection area the second flap is arranged on a second longitudinal side of the surface opposite the first longitudinal side, and wherein the profile has a third fold and a fourth fold extending from diagonally opposite longitudinal edges of the profile in mutually opposite directions. According to the invention, it is provided in particular that the profile, forming a transom, engages in a notch in the connection area of the rod. The notch can in particular be the notch already described above. In this way, a connection between a rod and a profile can be achieved in an advantageous manner, with the advantages already described above being able to be achieved.

In particular, the profile can be connected to the bar by means of a method described herein. All of the described versions can be used here.

The invention also relates to a device for producing a window frame or window frame part, wherein the window frame or window frame part consists of at least one longitudinal bar and a profile adjoining it at an angle, not at the corners of the bar, wherein the bar and the profile consist of welded plastic material, wherein the device is designed in particular for carrying out the method as described herein, and a welding mirror with at least essentially a Y-shaped or V-shaped cross section is provided for welding the profile to the rod.

The method described herein can be carried out in a particularly advantageous manner by means of such a device. With regard to the method, all of the versions described herein can be used. In particular, as already described, a welding mirror with a Y-shaped or V-shaped cross section can be used, with the advantages already described above being able to be achieved.

1 shows a first rod part 5a and a second rod part 5b for a process management according to a first embodiment. The following also relate to this exemplary embodiment Figures 2 to 4 .

The rod parts 5a, 5b are connected to form a rod 5 after being connected. This can, for example, form an underside or an upper side of a window frame.

A first rollover 10 is formed on the first rod part 5a. A second flap 20 is formed on the second rod part 5b. The flashovers protrude from a surface 7 of the rod 5, the surface 7 in the 1 shown is still disconnected, and in a connected condition is continuous except for the notch to be described.

The first flap 10 is arranged on a first longitudinal side 71 of the surface 7 . The second flap 20 is arranged on a second longitudinal side 72 of the surface 7 . The two longitudinal sides 71, 72 face each other with respect to the surface 7 as shown. A transition from the first rollover 10 to the second rollover 20 takes place at a connection area 8, which is shown in FIG 1 is formed between the two rod parts 5a, 5b.

The first flap 10 has a first face 11 . The second flap 20 has a second end face 21 . The first flap 10 has a greatest extension 12 which is arranged at the transition to the surface 7 as shown. Likewise, the second flap 20 has a greatest extent 22, which is arranged at the transition to the surface 7, as shown. This is done by beveling the two end faces 11, 21 in each case, with a cross section of the flaps 10, 20 becoming smaller towards the connection region 8. The first face has a recessed first face section 16 . The second face has a recessed second face section 26 . In the assembled state, the end face sections 16, 26 directly adjoin other end faces. In contrast, the respective remnants of the end faces 11, 21 form an overlap. This will be described in more detail below.

As further below with reference to 3 will be described in more detail, a notch is formed between the two rod parts 5a, 5b in the assembled state, with the chamfers on the end faces 11, 21 of the flaps 10, 20 also being able to be formed to produce respective chamfers.

2 shows a profile 100 for the procedure according to the first exemplary embodiment. The profile 100 extends along a longitudinal direction and has an at least substantially cuboid cross section. A third flap 130 protrudes from one edge and a fourth flap 140 protrudes from a diagonally opposite edge. The profile 100 has a longitudinal end 110, with the rollovers 130, 140 on the respective end faces 131, 141 merging into respective bevels 112, 114 of the profile 100 and tapering to a point towards the longitudinal end. Accordingly, the third flap 130 has its greatest extent 132 at the longitudinal end 110, and the fourth flap 140 also has its greatest extent 142 at the longitudinal end 110.

Cheeks 103, 104 are formed laterally on the profile 100, these merging into a respective rollover 130, 140. As shown, these are partially milled away from the longitudinal end 110 so that they are complementary to the rod 5 .

3 shows the bar parts 5a, 5b after they have been assembled to form the bar 5. They were welded to one another in the middle. As a result, the two rod parts 5a, 5b form a notch 6, which is also defined by bevels formed as an extension of the end faces 11, 21 of the flaps 10, 20.

Furthermore, respective cavities 14, 24 are formed in the flaps 10, 20, which are open towards the notch 6 in the present state. It will be shown later that these can be closed by profile 100.

In the notch 6, the in 2 shown end of the profile 100 are inserted, in particular in such a way that the longitudinal end 110 engages in the notch 6, the notch 6 being formed complementary to the bevels 112, 114. As a result, the position and orientation of the profile 100 relative to the rod 5 are precisely defined.

A suitably assembled state is in 4 to see. It can also be seen here that the cheeks 103 , 104 rest on the outer sides of the rod 5 in a complementary manner. A longitudinal extent of the profile 100 is transverse to the longitudinal extent of the bar 5, which corresponds to the typical design of a window frame. The respective cavities within the rollovers 10, 20, 130, 140 are closed by the other element, i.e. rod 5 or profile 100, in the area where rod 5 and profile 100 adjoin one another, so that air or moisture cannot penetrate is prevented.

figure 5 shows rod parts 5a, 5b for a rod 5 for a process control according to a second embodiment. In contrast to the first exemplary embodiment, they overlap here Overlaps 10, 130 or 20, 140 are not, but the overlays 10, 20 are only milled off in such a way that their end faces 11, 21 can directly adjoin end faces 131, 141 of the third and fourth overlays 130, 140. An intermediate region 9 is formed here, which is formed along the longitudinal extent of the rod 5 between the first flap 10 and the second flap 20, so that in contrast to the first exemplary embodiment the flaps 10, 20 do not directly adjoin one another with respect to the longitudinal direction.

A first cheek 15 is formed immediately adjacent to the first flap 10 . A second cheek 25 is also formed immediately adjacent to the second flap 20 . These are seen in a transverse direction of the bar 5 overlapping with the respective flap 10, 20 or its outer side, so that the bevelling of the respective end face 11, 21 of the respective flap 10, 20 is not carried out in one work step with the formation of the notch 6 . Rather, the respective end face 11, 21 is formed using a separate tool, not shown, which is typically smaller, so that the respective cheek 15, 25 is retained.

6 shows a profile 100 for the second embodiment. The end faces 131, 141 of the third and fourth flaps 130, 140 are designed to be flat with the bevels 112, 114, as shown, so that processing in one work step is possible here. The planar design of the end faces 131, 141 corresponds to the fact that they should lie flat against the end faces 11, 21 of the first flap 10 and the second flap 20, which are also designed to be flat, as in figure 5 shown.

7 shows an assembled state of the rod 5 of FIG figure 5 and the profile 100 from 6 . It can be seen that the rollovers 10, 130 and 20, 140 are not as in 4 overlap, but merely adjoin each other along respective connecting lines. In this way, a miter is produced which assumes an angle of 45° with respect to the longitudinal extensions of the bar 5 and the profile 100 .

8 shows rod parts 5a, 5b for a rod 5 for a process control according to a third embodiment. The third exemplary embodiment essentially corresponds to the first exemplary embodiment, with the first and second flaps 10, 20 being thinner in the third exemplary embodiment, viewed in the transverse direction of the rod 5, than in the first exemplary embodiment. Likewise shows 9 a profile 100 for the procedure according to the third exemplary embodiment, which is adapted to the rod 5 according to the third exemplary embodiment, but otherwise essentially corresponds in terms of its characteristics to the profile 100 according to the first exemplary embodiment.

10 shows the bar 5 and the profile 100 in an assembled state according to the third embodiment in a perspective view. Here again it can be seen that the second flap 20 and the fourth flap 140 partially overlap on the outside, a miter with an angle of 45° also being formed in this case. Respective cavities are closed by the respective other element.
