Title: Corner joint member for joining profiled tubular rods
The invention relates to a corner joint member for joining profiled tubular rods under and angle with respect to each other. Such corner joint members and tubular rods in a connecting state result in a profiled tubular rod assembly for use in for example door frames, window frames and/or cupboard frames.
5 Such corner joint members are known in the state of art. When assembling a profiled tubular rod assembly profiled tubular rods are often joined to each other under angle. This angle is often 90 degrees. Corner joint members comprise often a first element and a second element that are welded to each other under an angle that is equal to a desired angle of to be joined profiled tubular rods. The first element and the second element define 10 a so called mitred corner joint. Welding such a mitred corner joint is well known in the state of art and is for example disclosed in US-2010/0071834. Here, two elements under an mitre angle of 45 degrees are welded to each other by means of vibration welding. The elements have mitre areas that contact each other when they are in a desired connecting state. By means of welding the mitre areas together a corner joint member is provided which is 15 suitable to be connected with the profiled tubular rods.
Drawback of corner joint members having a welded mitred joint is that after welding irregularities arise. These irregularities must be removed to acquire a smooth outer surface of the corner joint member. Another drawback is that the weld is a weak point when forces or moments are exerted on one of the joined profiled tubular rods.
20 It is an object of the present invention to eliminate the abovementioned problems or at least provide an alternative.
In particular it is an object of the present invention to provide a corner joint member that has little irregularities while providing sufficient strength.
This object is received by a corner joint member according to claim 1.
25 This corner joint member is suitable for joining a first profiled tubular rod under an angle with a second profiled tubular rod by connecting ends of the first rod and the second rod to the corner joint. Preferably, each tubular rod comprises a substantially rectangular profile. The profile is defined as a contour of the profiled tubular rod seen in a direction perpendicular to a longitudinal axis of the profiled tubular rod. Preferably, the profile is such 30 that an outer contour is rectangular. Preferably, the profile has a square shape.
-2-
The corner joint member comprises a first profiled connector element having a first rod connecting end for connecting to the first rod. The first rod connecting end is open. The first profiled connector element is also a profiled tubular rod having two ends. The first profiled connector element is hollow and profiled. The first rod connecting end being hollow 5 results in the first connecting end being open.
Preferably, the first rod connecting end has a profile similar to the profile of the first rod. This is advantageous as when the first profiled tubular rod is connected to the first rod connecting end, a smooth connection with little irregularities may be acquired.
The first profiled connector element further comprises a first oblique end opposing 10 the first rod connecting end. The first oblique end is open and has a profile. The first oblique end is open resulting from the first profiled connector element being hollow.
The first profiled connector element defines a first interior space limited by the first rod connecting end, the first oblique end and a first inner contour surface of the first element. As the first profiled connector element is hollow it defines the first interior space.
15 The first inner contour surface extends circumferentially along a longitudinal axis of the first profiled connector element.
The corner joint member comprises a second profiled connector element having a second rod connecting end for connecting to the second rod. The second rod connecting end is open. The second profiled connector element is also a profiled tubular rod having two 20 ends. The second profiled connector element is hollow and profiled.
Preferably, the second rod connecting end has a profile similar to the profile of the second rod. This is advantageous as when the second profiled tubular rod is connected to the second rod connecting end, a smooth connection with little irregularities may be acquired.
25 The second profiled connector element comprises a second oblique end opposing the second rod connecting end. The second oblique end is open and has a profile. The second oblique end is open resulting from the second profiled connector element being hollow.
The second profiled connector element defines a second interior space limited by the 30 second rod connecting end, the second oblique end and a second inner contour surface of the second element. As the second profiled connector element is hollow it defines the interior space. The second inner contour surface extends circumferentially along a longitudinal axis of the second profiled connector element.
Oblique means that an oblique end lies in a plane that is under and angle with 35 respect to a longitudinal axis of a profiled connector element. The angles of the oblique ends depend on a desired angle between a connected first rod and second rod.
-3-
The first oblique end profile is similar to the second oblique end profile, such that in a connecting state, when the first oblique end profile adjoins to the second oblique end profile, a closing seam is defined between the oblique ends.
No weld is provided in the closing seam. As the first oblique end profile is similar to 5 the second oblique end profile, and no weld is provided in the closing seam, a smooth outer contour surface of the profiled connector elements is acquired with little irregularities.
The corner joint member is arranged in the connecting state and further comprises an auxiliary insert arranged in the first- and second interior space. The auxiliary insert for example is box shaped. When the first- and second oblique end profiles are square shaped, 10 the auxiliary insert preferably is a cube that fits within the profiled connector elements in the interior spaces.
An outer contour surface of the auxiliary insert contacts the first inner contour surface of the first profiled connector element as well as the second inner contour surface of the second profiled connector element. By contacting the inner contour surfaces of the first- and 15 second profiled connector elements it fits within said first- and second profiled connector elements.
The first inner contour surface extends along the longitudinal axis of the first profiled connector element and the second inner contour surface extends along the longitudinal axis of the second profiled connector element.
20 The corner joint member further comprises at least one first element weld between the outer contour surface of the auxiliary insert and the first inner contour surface.
The first element weld connects the auxiliary insert to the first profiled connector element. Preferably, each corner of the first inner contour surface, seen in a transverse plane perpendicular to the longitudinal axis of the first profiled connector element, is welded 25 to the outer contour surface of the auxiliary insert.
The corner joint member further comprises at least one second element weld between the outer contour surface of the auxiliary insert and the second inner contour surface.
The second element weld connects the auxiliary insert to the second profiled 30 connector element. Preferably, each corner of the second inner contour surface, seen in a transverse plane perpendicular to the longitudinal axis of the second profiled connector element, is welded to the outer contour surface of the auxiliary insert.
Having no weld in the closing seam results in a smooth outer contour surface of the first- and second profiled connector element. The first- and second element weld instead is 35 provided respectively on the inner contour surfaces. These welds cannot be seen by a person. The respective welds are provided by means of a welding head reaching the interior spaces through openings of respectively the first- and second rod connecting ends. The -4- openings are suitable for receiving the welding head and result from the respective rod connecting ends being open, i.e. having an open profile.
The auxiliary surfaces are therefore arranged within both the first- and second profiled connector elements, more in particularly in the respective first- and second interior 5 spaces. As the auxiliary inserts are welded to the first- and second profiled connector elements, the auxiliary insert provides more support to the first- and second profiled connector elements. Moreover, as the first - and second profiled connector elements contact the auxiliary surface, more support is provided such that forces exerted on the first profiled connector element is transferred more easily to the second profiled connector 10 element and vice versa.
This results in a corner joint member that has little irregularities while providing sufficient strength.
Having no weld in the closing seam and providing the corner joint member with the auxiliary insert further has as advantage that a more accurate corner joint member may be 15 provided.
The corner joint member connect the first profiled tubular rod and the second profiled tubular rod under a desired angle. It often is desired that the actual angle has a certain accuracy with respect to the desired angle. In particularly, when the corner joint member and the first- and second profiled tubular rods are part of an assembly, it may be desired that this 20 assembly comprises profiled tubular rods that are arranged under an angle, wherein the actual angle is within a fault margin, i.e. has a desired accuracy. The auxiliary insert allows a more accurate angle as during welding of the corner joint member to the first- and second profiled connector elements, said first- and second profiled connector elements are supported by said auxiliary insert. Less unwanted movement of the first profiled connector 25 element with respect to the second profiled connector element may arise during welding.
In an embodiment of the corner joint member according to the invention, material of the auxiliary insert has a smaller mass than the mass of the first- and second profiled connector elements such that, near the first- and second weld, material of the auxiliary insert 30 expand more during welding and cools faster after welding compared to material of the first-and second profiled connector elements.
During welding the auxiliary insert expands due to heating, while the auxiliary insert is connected to the first- and second profiled connector elements. After welding, the auxiliary insert as well as the first- and second profiled connector elements need to cool down. As the 35 mass of the auxiliary insert is smaller, the auxiliary insert shall cool down faster than the first-and second profiled connector elements. The auxiliary insert shall therefore shrink more.
-5-
This is advantageous as the first profiled connector element is pressed against the second profiled connector element as the auxiliary insert shrinks more than the profiled connector elements. Therefore, the first oblique end is pressed against the second oblique end upon cooling after welding. This results in a closing seam has even less irregularities as 5 irregularities are removed due to the pressing of the first- and second oblique ends to each other.
In an embodiment of the corner joint member according to the invention, the auxiliary insert is sized such that, near the first- and second weld, material of the auxiliary insert expand more during welding and cools faster after welding compared to material of the first-10 and second profiled connector element.
In a preferred embodiment, the auxiliary insert is hollow. This is advantageous as it reduces mass, such that the auxiliary inserts cools down faster after welding. The auxiliary insert comprises a hollow shape such that the mass is as little as possible, however providing sufficient stiffness for providing support to the first- and second profiled connector 15 elements.
Further preferably, the auxiliary insert comprises a reinforcement means arranged inside the auxiliary insert, wherein the reinforcement means is arranged perpendicular with respect to the closing seam.
This allows a hollow auxiliary insert with little mass while still providing sufficient 20 stiffness such that the auxiliary insert is able to distribute forces exerted on the corner joint member.
In an embodiment of the corner joint member according to the invention, an edge of the auxiliary insert comprises a bevel.
The edge is defined by at least two sides of the auxiliary insert. The bevel creates an 25 additional side, in other words, it defines an additional outer contour surface of the auxiliary insert. When the auxiliary insert is arranged in the first- and second interior space, the auxiliary insert fills the first- and second interior space. The bevel allows the first- and second interior space to be filled less compared with an absence of the bevel. The bevel therefore defines an auxiliary interior space limited by the bevel of the auxiliary insert and 30 part of the inner contour surface of the first- and second profiled connector elements.
The part of the inner contour surface of the first- and second profiled connector elements is preferably near corners, seen in a plane perpendicular to a longitudinal axis of the respective profiled connector element, wherein said corners are the corners defined by a longest side of the respective profiled connector elements.
35 This has as advantage that it allows the auxiliary insert to fit snugly in the first- and second interior space. Moreover, near said corners defined by the longest side of the respective profiled connector elements, burs may occur that may result in an irregular fitting -6- of the auxiliary insert. As a result of the bevel and defining of the auxiliary interior space, the burs may be located in the auxiliary interior space, such that the burs do not result in contacting the auxiliary insert and thus avoiding inaccuracies and irregularities.
In an embodiment of the corner joint member according to the invention, at least one 5 of the first- and second profiled connector elements comprises in its corners, seen in a plane perpendicular to a longitudinal axis of the respective profiled connector element, a recess extending away from the inner contour surface of the respective profiled connector element.
This is advantageous as it allows the auxiliary insert to fit snugly in the first- and second interior space.
10 In an embodiment of the corner joint member according to the invention, the auxiliary insert is box shaped.
This is advantageous as the outer contour surface of the auxiliary insert contacts the first profiled connector element in three planes of the first inner contour surface and it contacts the second profiled connector element in three planes of the second inner contour 15 surface. This may provide even more support, resulting in a more strong corner joint member.
In an embodiment of the corner joint member according to the invention, wherein the first- and second oblique end profiles are square shaped and the auxiliary insert is cube shaped.
20 This is advantageous as the outer contour surface of the auxiliary insert contacts the first profiled connector element in three planes of the first inner contour surface and it contacts the second profiled connector element in three planes of the second inner contour surface. This may provide even more support, resulting in a more strong corner joint member.
25 In an embodiment of the corner joint member according to the invention, the corner further comprises a third profiled connector element. The third profiled connector element has a third rod connecting end for connecting to a third profiled tubular rod. Preferably, the profile of the third rod connecting end is similar to the profile of the third profiled tubular rod. The third profiled connector element has a third end opposing the third rod connecting end.
30 The third end adjoins an outer contour surface of both the first- and second profiled connector element. The third end partly overlaps the outer contour surfaces of the first- and second profiled connector elements. A longitudinal axis of the third profiled connector element is perpendicular to a plane comprising longitudinal axes of respectively the first- and second profiled connector elements. This means that the third profiled connector element is 35 perpendicularly arranged with respect to the first- and second profiled connector elements. This is advantageous as the third profiled tubular rod can be arranged perpendicular to the first- and second profiled tubular rods. The third profiled connector element defines a third -7- interior space limited by the third rod connecting end, the third end and a third inner contour surface of the third element. At least one third element weld is provided between the outer contour surface of the first- and second profiled connector element and the third inner contour surface.
5 The third element weld is provided by a welding head that is received in the third interior space through the third rod connecting end. The third rod connecting end therefore comprises an opening. The opening is suitable for receiving the welding head and the opening results from the third rod connecting end being open, i.e. having an open profile.
This is advantageous as a closing seam between on the one hand the first- and 10 second profiled connector elements and on the other hand the third profiled connector elements is free from a weld. The closing seam is defined between on the one hand the outer contour surface of the first- and second profiled connector elements and on the other hand the profile of the third end. Instead of a weld in the closing seam, the connection is provided internal of the third profiled connector element, namely on the third inner contour 15 surface. As the weld is internal, little irregularities arise in the closing seam.
Preferably, the profile of the third profiled connector element is rectangular and the third element welds are provided at least in the corners seen in a transverse plane perpendicular to the longitudinal axis of the third profiled connector element.
20 The invention further relates to a method for manufacturing a corner joint member according to claim 10. Particularly, it relates to a corner joint member according to one of the previous embodiments.
The method comprises the step of adjoining a first oblique end of a first profiled tubular element to a second oblique end of a second profiled tubular element, wherein a first 25 oblique end profile is similar to a second oblique end profile.
The method further comprises the step of inserting an auxiliary insert at least partly into a first interior space and a second interior space. The first interior space is limited by the first oblique end and a first inner contour surface of the first profiled tubular element. The second interior space is limited by the second oblique end and a second inner contour 30 surface of the second profiled tubular element.
The step of adjoining and inserting may be performed in random order. For example, firstly the first oblique end is adjoined to the second oblique end and subsequently the auxiliary insert is inserted into the first- and second interior spaces. The auxiliary insert may pass through an opposing end that is open. In an alternative example, the auxiliary insert is 35 firstly inserted into the first interior space and secondly the second profiled connector element is slid over the auxiliary insert, such that the second interior space receives the -8- auxiliary insert. The auxiliary insert is received into the second interior space by passing through an open end opposing the second oblique end.
The method further comprises the step of receiving a welding head respectively in the first- and second interior space through respectively the first- and second rod connecting 5 end. The first rod connecting end of the first profiled connector element opposes the first oblique end and has an open profile. The second rod connecting end of the second profiled connector element opposes the second oblique end and has an open profile. Therefore, after the auxiliary insert is received into the interior spaces, also the welding head is subsequently received in the interior spaces.
10 Preferably, only one welding head is subsequently received in respectively the first- and second interior space or vice versa. Alternatively, more than one welding head is available which allows simultaneously receiving a respective welding head in the first- and second interior spaces.
The method further comprises the step of welding the auxiliary insert to the first- and 15 second profiled tubular element by respectively providing at least one first element weld between an outer contour surface of the auxiliary insert and the first inner contour surface and by providing at least one second element weld between the outer contour surface of the auxiliary insert and the second inner contour surface.
The at least one element weld are provided by the welding head that are received in 20 the interior spaces. While the welding head is received in the interior spaces the respective inner contour surfaces of the profiled connector elements can be reached such that they can be welded to the outer contour surface of the auxiliary insert.
The at least one first element weld is provided by the welding head when received in the first interior space. The at least second element weld is provided by the welding head 25 when received in the second interior space.
This method is particularly advantageous while a closing seam between the first- and second oblique end is free from a weld. Instead, the weld is provided internal of the first- and second profiled connector elements. This results in less irregularities.
Moreover, the auxiliary insert provides support to the first- and second profiled 30 connector elements. This results in a more strong corner joint member.
In an embodiment of the method according to the invention, each corner of the first inner contour surface, seen in a transverse plane perpendicular to a longitudinal axis of the first profiled connector element, is welded to the outer contour surface of the auxiliary insert. 35 This is advantageous as it provides an optimal connection as these corners provide a relatively large inner contour surface of the first profiled connector element as the surface extends in two planes.
-9-
In an embodiment of the method according to the invention, each corner of the second inner contour surface, seen in a transverse plane perpendicular to a longitudinal axis of the second profiled connector element, is welded to the outer contour surface of the auxiliary insert.
5 This is advantageous as it provides an optimal connection as these corners provide a relatively large inner contour surface of the second profiled connector element as the surface extends in two planes.
In an embodiment of the method according to the invention, a continues weld is applied along the total profile of the first inner contour surface, seen in a transverse plane 10 perpendicular to a longitudinal axis of the first profiled connector element.
This is advantageous as the first element weld is relatively large compared to multiple smaller first element welds, therefore providing more strength.
In an embodiment of the method according to the invention, wherein a continues 15 weld is applied along the total profile of the second inner contour surface, seen in a transverse plane perpendicular to a longitudinal axis of the second profiled connector element.
This is advantageous as the second element weld is relatively large compared to multiple smaller second element welds, therefore providing more strength.

The profiled tubular assembly further comprises a first profiled tubular rod connected 25 to a first rod connecting end of the first corner joint member. The first profiled tubular rod has a profile similar to the first rod connecting end.
The connection of the first rod connecting end to the first profiled tubular rod may be provided by a conventional connection means, such as a pin-hole connection. The pin may be sunken in the first profiled connector element or the first profiled tubular rod.
30 This results in an assembly with a corner joint member having little irregularities near a closing seam and an increased strength compared to the state of art.
In an embodiment of the profiled tubular rod assembly according to the invention, the profiled tubular assembly further comprises a longitudinal profiled receiving element for receiving a plate like element.
35 The plate like element may for example be a glass plate or a wooden plate. The plate like element is fixed with respect to the profiled tubular rods, or in other words, the profiled tubular rods keep the plate like element in place.

The corner joint member 1 comprises a first profiled connector element 11 having a first rod connecting end 12 for connecting to the first rod 10, wherein the first rod connecting end 12 is open and has a profile similar to the profile of the first rod 10. The first profiled connector element 11 further comprises a first oblique end 13 opposing the first rod 5 connecting end 12. The first oblique 13 end is open and has a profile, wherein the first profiled connector element 11 defines a first interior space A. The first interior space A is limited by the first rod connecting end 12, the first oblique end 13 and a first inner contour surface 14 of the first element 11.
The corner joint member also comprises a second profiled connector 21 element 10 having a second rod connecting end 22 for connecting to the second rod 20. The second rod connecting end 22 is open and has a profile similar to the profile of the second rod 20. The second profiled connector element 21 comprises a second oblique end 23 opposing the second rod connecting end 22. The second oblique end 23 is open and has a profile, wherein the second profiled connector element 21 defines a second interior space B.

The second element welds 25a, 25b, 25c, 25d weld the first profiled connector element 11 to the outer contour surface 6 of the auxiliary insert 5.
Note that the longitudinal axis X1 of the first profiled connector element 11 is 10 perpendicularly arranged, i.e. 90 degrees, with respect to the longitudinal axis X2 of the second profiled connector element 21. Therefore, the connected first profiled tubular rod 10 is arranged with an angle of 90 degrees with respect to the connected second profiled tubular rod 20.
Material of the auxiliary insert 5 has a smaller mass than the mass of the first profiled 15 connector 11. Also the material of the auxiliary insert 5 has a smaller mass than the mass of the second profiled connector elements 21. This results in that, near the first- and second weld 15, 25, the material of the auxiliary insert 15 expands more during welding and cools faster after welding compared to material of the first- and second profiled connector elements 11, 21.
20 The auxiliary insert 5 is hollow. The first- and second oblique end profiles are square shaped and the corresponding auxiliary insert 5 is cube shaped.

Figure 7 shows a top view of a corner joint 201 according to another embodiment of the invention. In particularly it shows an auxiliary insert 205 which is hollow. This reduces the mass of the auxiliary insert such that the mass is lower than the mass of first- and second profiled connector elements 11,21 in which the auxiliary insert 205 is inserted.
15 This is advantageous as it reduces mass, such that the auxiliary insert 205 cools down faster after welding. The auxiliary insert 205 comprises a hollow shape such that the mass is as little as possible, however providing sufficient stiffness for providing support to the first- and second profiled connector elements 11, 21.
Further preferably, the auxiliary insert comprises a reinforcement means 60 arranged 20 inside the auxiliary insert 205, wherein the reinforcement means 60 is arranged perpendicular with respect to the closing seam 3.
This allows a hollow auxiliary insert 205 with little mass while still providing sufficient stiffness such that the auxiliary insert 205 is able to distribute forces exerted on the corner joint member 201.
25 Figure 8 shows a top view of a corner joint member 301 further comprising an auxiliary insert 305 of which an edge 66 comprises a bevel 65.
The edge 66 is defined between two sides 67a, 67b of the auxiliary insert 305. The bevel 65 creates an additional side, being actually the edge 66. In other words, it defines a different shape of the additional outer contour surface 6 of the auxiliary insert 305. When 30 the auxiliary insert 305 is arranged in the first- and second interior space A, B, the auxiliary insert 305 fills the first- and second interior space A, B. The bevel 65 allows the first- and second interior space A, B to be filled less compared with an absence of the bevel 65. The bevel 65 therefore defines an auxiliary interior space C limited by the bevel 65 of the auxiliary insert 305 and part of the inner contour surfaces 14, 24 of the first- and second 35 profiled connector elements 11, 21.
The part of the inner contour surfaces 14, 24 of the first- and second profiled connector elements 11,21 is preferably near corners, seen in a plane perpendicular to a - 16- longitudinal axis X1, X2 of the respective profiled connector element 14, 24, wherein said corners are the corners defined by a longest side of the respective profiled connector elements 14, 24.
This has as advantage that it allows the auxiliary insert 305 to fit snugly in the first-5 and second interior space A, B. Moreover, near said corners defined by the longest side of the respective profiled connector elements 11, 21, burs may occur that may result in an irregular fitting of the auxiliary insert 305. As a result of the bevel 65 and defining of the auxiliary interior space C, the burs may be located in the auxiliary interior space C, such that the burs do not result in contacting the auxiliary insert 305 and thus avoiding inaccuracies 10 and irregularities.
In an embodiment of the corner joint member 401 according to the invention, at least one of first- and second profiled connector elements 411, 421 comprises in its corners, seen in a plane perpendicular to a longitudinal axis X1, X2 of the respective profiled connector element 411, 421, a recess 67a, 67b, 67c, 67d extending away from the inner contour 15 surface 14, 24 of the respective profiled connector element 411, 421.
This is advantageous as it allows an auxiliary insert 5 to fit snugly in the first- and second interior space A, B.
In figures 7-9, a space is indicated between the auxiliary insert 205, 305, 5 and the respective profiled connector elements 11, 21, 411, 421. However, this space is to more 20 clearly indicate where the profiled connector elements 11, 21, 411,421 limit the respective auxiliary insert 205, 305, 5. When the corner joint member 201, 301, 401 is assembled the auxiliary insert 205, 305, 5 snugly fits in the respective profiled connector elements 11, 21, 411, 421. Or in other words, the outer contour surface of the auxiliary insert 205, 305, 5 contact the inner contour surface of the respective profiled connector elements 11,21, 411, 25 421.
