Description
Profile joints and related methods
Field of the Invention
The present invention relates to the field of joints for profile sections, particularly profile sections used in window or doors. It further relates to methods of forming such joints, methods of preparing profile sections and to windows and doors constructed using such joints.
B,g( round to the Invention In recent years, windows and doors have progressed from the use of wood to plastic materials such as PVC-U. It is known that tie use of plastic materials provides many physical advantages. However, plastic materials do not possess the same appearance of products made from wood using traditional timber joinery techniques and can be more complicated to join. Plastic windows and doors typically have an outer frame for mounting within a wall and an inner frame for mounting within the outer frame, the inner frame having a glazing unit mounted therein. The inner frame and glazing unit combination is typically referred to as a sash or leaf The sash is moveable relative to the outer frame to open and close the sash.
The outer and inner frames are formed of a combination of horizontal and vertical sections.
The sections are extruded and often comprise complex cross sections. Such cross sections are typically jointed by welding end portions of each horizontal and vertical section, The most common form of joint for PVC-U profile sections is a welded mitre joint. However, manufacturers are increasingly looking for ways in which windows and doors made from PVC-U profile sections can emulate the appearance of traditional timber joinery, thereby providing the improved thermal insulation of PVC-U frames but with a traditional appearance. Wooden windows and doors are usually constructed using butt joints, but this is difficult to achieve with plastic profile sections due to the complex shapes of plastic profile sections. A method was devised for joining lengths of complex profiled plastic extrusion to give the appearance of a butt join, which is described in GB2430720, the contents of which is incorporated by reference A downside of joining plastic profile sections by welding is that an amount of excess material typically forms around the joint which, even after finishing (e.g. by cutting the excess material away), may affect the appearance of the joint. Therefore, even if the external faces of the profile sections are joined with butt joints, the joint will still give the appearance of a plastic joint rather than a joint between two timber sections.
The present invention seeks to provide an improved plastic joint and improved methods of forming a plastic joint between two profile sections.
Summary of the Invention
According to a first aspect of the invention there is provided a profile joint connecting two profile sections, the profile sections each having first and second opposed exterior faces and an interconnecting matrix, the first exterior face of each profile section having a rebate portion extending therefrom, the interconnecting matrix at the end of each profile section being cut to form end faces at complimentary angles that join form a mitre joint, the rebate portion at the end of each profile section being cut to form end faces at complementary angles that join to form a mitre joint, and the first and second exterior faces being cut to form a butt joint, wherein the rebate portions are cut such that upon contacting the end faces of the interconnecting matrix with one another, a gap is provided between the end faces of the rebate portions prior to forming the profile joint.
The formation of welded mitre joints produces external weld sprue (also known as flash) at the welded joint, which is removed after welding for functional and aesthetic reasons.
Even after removal of the sprue, an imperfect surface is left behind, giving prior art welded joints the distinctive appearance of a plastic welded joint. If using a method to form a profile joint that gives the appearance of a butt joint, sprue is still formed at the mitre joint between the rebate portions of the two profile sections being joined. The present invention aims to overcome this problem. This avoids the need to remove sprue after a joint has been welded. By using a profile joint according to the present invention, unsightly sprue does not form at the joint of the rebate portions during welding of the profile joint.
The present invention is equally applicable to windows and doors and to a profile joint of an outer frame for receiving a sash or a joint of a sash frame itself. References herein to window frames includes door frames and vice versa. Reference herein to frames include the outer frame and inner frame of a window or door.
The gap provided between the end faces of the rebate portions prior to forming the profile joint provides a void or break in material between the rebate portions when the outer frame portions are brought into abutment prior to welding the profile joint.
The gap provided between the end faces of the rebate portions prior to forming the profile joint is preferably a predetermined size. The size of the gap is predetermined such that sprue is not formed at the joint between the rebate portions during welding of the joint, The gap provided between the end faces of the rebate portions prior to forming the joint may be between 2 mm and 8 mm, preferably between 4 mm and 6 mm, and even more preferably around 5 mm.
In the present invention the butt joints are made at a right angle and the mitre joint are formed at substantially 45°. This is achieved by cutting the matrix at the end of each profile section at an angle of 45° to the length of each profile section, which are generally elongate.
The first and second opposed exterior faces are preferably substantially parallel to each other, One of the first and second opposed exterior faces, when assembled in a window or door, will face into a building and the other will face out of the building.
Preferably the profile joint is formed by a horizontal profile section and a vertical profile section. Preferably each profile section is an extruded window or door profile section.
The profile sections are preferably made of plastic material. The plastics material profile sections usually comprise lengths of a complex profiled plastic extrusion from which inner or outer frames for a windows or door are constructed.The profile does not, however, have to have been formed by extrusion; a profile formed by any other suitable method may still be used. The matrix extending between the external faces can be substantially solid, or can comprise an arrangement of interconnecting walls that may define spaces therebetween.

The term plastic includes composite materials such as fibreglass, composite materials consisting of PVC-U with fillers such as sawdust, as well as normal plastic material such as PVC-L.1 According to another aspect of the invention there is provided a method of preparing a profile section having first and second opposed exterior faces, an interconnecting matrix, and a rebate portion extending from the first exterior face, the method comprising the steps of: cutting the interconnecting matrix of an end of a first profile section to a mitred face, cutting material from the rebate portion of the first profile section such that when the mitred end face of the first profile section is butted against a corresponding mitred face of a second profile section with a corresponding rebate portion, a gap is provided between an end face of the rebate portion of the first profile section and an end face of the rebate portion of the second profile section. The cutting steps may be performed in any order.
The profile section, once prepared according to the above method can then be joined with another profile section, preferably prepared according to the same method, to form a profile joint according to the first aspect of the invention, The method is subject to many of the same preferred aspects as discussed above with respect to the profile joint. The step of cutting the interconnecting matrix of an end of a first profile section to a mitred face may include cutting the rebate portion at the same angle as that of the interconnecting matrix; material is then cut from the rebate portion. In this way a gap is provided between an end face of the rebate portion of the first profile section and an end face of the rebate portion of the second profile section when assembled prior to welding.
The method may further comprise cutting of the first and second opposed exterior faces so that they are cut square.
The material removed from one or both of the rebate portions of the first and second profile sections that are assembled together to form the joint is such as to provide a gap of around 2 to 8 mm, preferably 4 to 6 mm, even more preferably around 5 mm prior to welding.
The gap may be provided by removal of between 1 mm and 4 mm of material from the end face of the rebate portion of at least one of the connecting profile sections; or by removal of between 2 mm and 3 mm of material from the end face of the rebate portion of at least one of the connecting profile sections; or by removal of 2.5 mm of material from the end face of the rebate portion of at least one of the connecting sections. In particularly preferred embodiments the gap is provided by removal of around 2.5 mm material from the rebate portion of a first profile section and around 2.5 mm material from the rebate portion of a second profile section to be connected to form the joint, forming a gap of around 5 mm between the end faces of the rebate portions when assembled prior to forming the joint.
A clockwise cutting tool is preferably used for cutting the interconnecting matrix in order to mitre a right hand corner of a profile section. An anti-clockwise cutting tool is preferably used for cutting the interconnecting matrix in order to mitre a left hand corner of a profile section.

The cutting steps may be performed in any order.
The method is subject to many of the same preferred aspects as discussed above with respect to the profile joint. It is preferred that the matrix of each section is cut at substantially 45°, and the sections are joined at 90° to each other. The profile sections may be joined by heat welding, ultra-sonic welding or adhesives such as epoxy glues are possible. Cutting of the ends of each section of profile is achieved by any appropriate method, preferably precision milling using appropriately shaped cutting heads.

Description of the Preferred Embodiments
The profile joint of the present invention can be used in windows or doors. Windows and doors typically comprise a sash (also known as a leaf), comprising an inner frame with a glazing unit mounted therein, the sash being mounted in a fixed outer fra me. The inner and outer frame of the window or door are typically made from extruded profile sections made of a plastics material such as unplasticized polyvinyl chloride (PVC-U). An outer frame of this type is constructed from four extruded profile sections, which are fixed together to form a rectangular structure in which the sash can be mounted. Similarly, the sash is constructed from four extruded profile sections, which are fixed together to form a rectangular inner frame, forming a closed perimeter for receiving a rectangular glazing unit. The sash may be pivotally or slidingly mounted in the outer frame. The profile joint of the present invention can be used in an inner frame and/or outer frame of a window or door.
Figure 1 shows a completed profile joint of a sash (i.e. a joint of the inner frame of a window or door in accordance with the present invention).The sash has an 'internal' side (i.e. a side which is configured to face into a building) and an 'external' side (i.e. a side which is configured to face out of the building). Figure 1 shows the profile joint as viewed from the external side of the sash.Two profile sections are connected to form the profile joint. The profile joint comprises a horizontal section 10 and a vertical section 11. Each section may be a length of an elongate extrusion, typically manufactured from plastic. The Horizontal section 10 comprises a first exterior face 13 and a rebate portion 14 extending from the first exterior face. The rebate portion 14 of the horizontal section 10 has an inner lip 15 which runs along the entirety of the inner edge of the rebate 14.The vertical section 11 comprises a first exterior face 16 and a rebate portion 17. The rebate portion 17 of the vertical section 11 has an inner lip 18 which runs along the entirety of the inner edge of the rebate portion 17. The profile joint can be seen in figure 1 as 19.
Both the horizontal and vertical sections 10, 11 comprise a core or interconnecting matrix 20 of internal walls, shown generally in figures 2 and 3. The matrix 20 is designed such that it provides the required structural properties for use in the intended application.The shape of the internal matrix 20 may vary and is not limited to the pattern shown in figures 2 and 3.
Referring to figure 3, the vertical section 11 has a second exterior face 30 opposing the first exterior face 16. In this embodiment, the first exterior face 16 is intended to be on the external side of the sash (i.e. facing out of a building) and the second exterior face 30 is intended to be on the internal side of the sash (i.e. facing into a building). The first and second opposing exterior faces 16, 30 form the visible faces of the sash when the sash is mounted in an outer frame. The first and second opposing exterior faces 16,30 are substantially fiat and are preferably parallel to each other. The rebate portion 17 extends from the first exterior face 16, the rebate portion 17 running along the entirety of the inner edge of the first exterior face 16. The rebate portion 17 supports a gasket 31 which seals against a glazing unit (not shown). A glazing bead (not shown) is retained in an undercut groove 32 on the inner edge of the second exterior face 30 to hold the glazing unit in place.
Referring to figure 2, like the vertical section 11, the horizontal section 10 has a second exterior face (not visible in the figures) opposing the first exterior face 13.1n this embodiment, the first exterior face 13 is intended to be on the external side of the sash and the second exterior face is intended to be on the internal side of the sash.The rebate portion 14 extends from the first exterior face 13, the rebate portion 13 running along the entirety of the inner edge of the first exterior face 13. The rebate portion 14 supports a glazing unit (not shown) in the same way as the vertical section.
The rebate portions 14, 17 of the horizontal and vertical sections may of course be on the internal side of the sash, in which case the external side of the profiles will each be configured to receive a glazing bead.
In the present embodiment the rebate portions 14, 17 are externally convexly curved.The rebate portions 14, 17 may alternatively be other shapes, such as externally concavely curved, or they may have substantially flat outer surfaces.
The rebate portion 14 of the horizontal section 10 is shown in figure 2 and comprises a mitred end face 21 which corresponds to a mitred end face 22 of the rebate portion 17 of the vertical section 11. The rebate portion 17 of the vertical section 11 is shown in figure 3. The rebate portion 17 of the vertical section 11 shown in figure 3 is mitred at its end. The mitred end face 22 of the rebate portion " 7 of the vertical section 11corresponds to the mitred end face 21 of the rebate portion " 4 of the horizontal section 10. The angle of the mitred joint is typically 45 degrees.
The end face 23 of the vertical section and the end face 24 of the horizontal section are cut to form mitred end faces to form a mitre joint.
The mitred faces 21,22 of the rebate portons 14, 17 may be manufactured such that when the end of the horizontal section 10 is aligned with the end of the vertical section 11so that the end faces 23,24 of the internal matrices 20 are flush, a gap is present between the mitred end faces of rebate portions 14, 17 as shown in figure 4.The gap (i.e. the distance between the mitred faces 21,22 of the rebate portions 14, 17) may be between around 2 mm and 8 mm, Preferably the gap is between 4 mm and 6 mm. More preferably the gap is 5mm.
The first exterior face 13, 16 of each of the horizontal and horizontal sections is cut to form a butt joint. Following cutting, the vertical section 11 comprises a lateral external face 25a which extends linearly beyond the mitrec end face 23 of the interconnecting matrix. The end of the horizontal section 10 is cut to form a complementary end formation to form the butt joint. The first exterior face 13 of the horizontal section 10 is cut at a right angle at a point roughly level with the inner (uppermost as viewed in figure 2) edge of the mitred end face 24 of the interconnecting matrix, leaving an end portion 25b of the interconnecting matrix extending beyond the cut end of the first exterior face 13. The laterally extending face 25a of the vertical section 11 overlaps the end portion 25b of the Horizontal section 10 once joined. The overlapping lateral face 25 covers the abutting joins between each mitred end face 23, 24 of the interconnecting matrix, providing a physical barrier to improve the appearance of the sash.The arrangement of the butt joint can of course be reversed (i.e. the first exterior face of the vertical section can be cut in order to be overlapped by the end of the first exterior face of the horizontal section).
In a second aspect of the invention a method of forming a profile joint between two or more profile sections 10, 11 is provided. Tie method may be carried out by an electronic milling machine, such as an automated multiple axis CNC machine. The method may be theoretically carried out manually, however the level of accuracy required would make this incredibly challenging due to the high level of complexity and it would be more time consuming. The method described herein produces four pieces which may be joined to form a rectangular frame. The method may be used to produce fewer or more pieces if required.
If using an automated multiple axis CNC machine to prepare the profile sections prior to joining the method may begin with providing two extruded lengths of horizontal plastic frame section and two extruded lengths of vertical plastic frame section, which are placed in the machine. A first cutting tool is selected by a moving tool arm.The first cutting tool trims the external faces of each vertical profile section 11.
The machine arm then moves to the horizontal profile sections 10 and t( ms the external faces of each horizontal profile section.
In the next step of the method the machine offloads the first cutting tool and loads a second, larger cutting tool, The second cutting tool is a designed to cut with a clockwise cutting action. The second cutting tool removes core material from a first vertical profile section (configured to be a right-hand vertical profile section) to form the mitred angle for the joint. This cutting tool cuts the interconnecting matrix and the rebate portion to form the mitred angle.
The machine then offloads the second cutting tool and loads a third cutting tool.The third cutting tool cuts in an anti-clockwise direction, The third cutting removes core material from the second vertical profile section and cuts the mitred angle for the join, to form a left-hand vertical profile section.This cutting tool cuts the interconnecting matrix and the rebate portion to form the mitred angle, In the next step the third cutting tool is offloaded and a drill cutter is loaded. The drill cutter removes material from the mitred end faces 22 of the rebate portion 17 of both of the vertical profile sections. The drill cutter removes material from the mitred end faces 21 of the rebate portion 14 of both of the horizontal profile sections. Removal of the rebate material provides a gap between corresponding mitred end faces 21,22 of the vertical and horizontal profile sections 10,11 when assembled. The drill cutter may remove material from each rebate 14, 17 such that the gap may be between 2 mm and 8 mm. Preferably the gap is between 4 mm and 6 mm. More preferably the gap is 5mm.
A horizontal profile section 10 end may be aligned with a vertical profile section 11 end. The horizontal profile section 10 end and vertical profile section 11 end may be joined. The profile joint is typically formed by welding. Other plastic joining methods may be used.
The gap (i.e. the negative or empty space) between the mitred faces 21, 22 of the rebate portions 14,17 formed by removal of material from each rebate portion 14,17 as described above provides a joint which produces no external weld sprue and requires no additional finishing.
By way of comparison, figures shows a known joined window sash after welding and before trimming of excess material has occurred. The sash comprises a horizontal profile section 26 and a vertical profile section 27. The protruding excess material 28 is shown along the joint 29. Removing the excess material 28 shown in figure 5 increases manufacturing time and material waste. Furthermore, excess material remains 28 visible on the finished joint 29 as shown in figure 6. Figure 1 shows the profile joint according to the present invention wherein there is no excess material remaining.
The profile joint and method of forming tie profile joint may be used in all types of windows or doors, including sliding sash or casement windows. The profile joint and method may be applicable to other window styles or joints of section which require mitred connections.
