Description

CLOSURE PIECE FOR USE AT A JOINT BETWEEN HOLLOW PROFILED
MEMBERS
This invention relates to the formation of joints between hollow profiled members. Examples of such members are those from which window frames are constructed, the profiled members often being of a plastics material, for example, unplasticised polyvinyl chloride (uPVC) or of a metal, for example a suitable aluminium alloy.
Particularly when the profiled members are of plastics material, they are often joined at the corners of window frames and other articles fabricated from lengths of the members by welded, mitred joints. These joints are unsightly and tend to make it apparent that the material of the frame is not the original timber but a replacement material instead.
The present invention allows a joint to be made between hollow, profiled members which avoids welding of the material of the members and allows the joint to have an appearance much closer to that of a joint between two portions of timber window frame.
The invention also addresses a problem which would otherwise arise when two hollow profiled members are joined by a butt joint. This is that the hollow interior of at least one of the members would otherwise be open at the joint, giving rise in turn to a further problem of ingress of damp and/or cold air in the case of a window frame and thereby with attainment of applicable energy ratings.
The invention provides a closure piece for use at a corner joint between two hollow profiled members, the piece comprising a base portion having a surface for fitting against an end surface of a first one of the hollow profiled members substantially to close the hollow interior of the member and, upstanding from the base portion, a first upstanding portion shaped for reception in the hollow interior of the hollow profiled member.
Preferably and spaced from the first upstanding member to define a gap therebetween, there is a second upstanding portion shaped for contact with a surface the first profiled member distant from the second profiled member with which the joint is made, the gap being shaped to receive an end portion of the outer wall of the first profiled member.
The first and second upstanding portions preferably have therethrough respective portions of a bore for receiving a fixing passing transversely through the end portion of the first profiled member and longitudinally into the second profiled member.
Preferably, the face of the second upstanding portion distant from the gap has a recess surrounding the bore extending therethrough, for reception of the head of a said fixing.
Advantageously, the second upstanding portion is shaped to fit in a trough formed between longitudinal ribs extending along the outer face of the first profiled member.
Conveniently, the second upstanding portion has a cuboidal shape.
Advantageously, the first upstanding portion has a transverse cross-section which corresponds to that of the hollow interior of a first profiled member with which the piece is to be used.
Preferably, the first upstanding portion has a hollow interior. More preferably, there is an internal partition extending across the hollow interior, the respective bore portion extending through the partition.
Advantageously, the support piece has at least one further upstanding portion shaped for reception in a cavity in one of the profiled members, or between the profiled members, when the joint is formed.
Conveniently, the support piece is formed in one piece from a plastics material.
The invention also provides a corner joint formed between first and second hollow profiled members joined at an angle, preferably at 9QO, to each other, and a closure piece comprising a base portion having a surface fitted against an end surface of a first one of the profiled members and, upstanding from the base portion, a first portion received in an end portion of the hollow interior of the first profiled member.
Preferably, the closure piece has, spaced from the upstanding portion to define a gap in which an end portion of the outer wall of the first profiled member is received, a second upstanding portion which is in contact with a surface the first profiled member distant from the second profiled member.
The first and second upstanding portions preferably have therethrough respective portions of a bore for receiving a fixing passing transversely through the end portion of the first profiled member and longitudinally into the second profiled member.
Advantageously, the second upstanding portion is received in a trough formed between longitudinal ribs extending along the outer face of the first profiled member, the second upstanding portion extending between respective inner surfaces of the ribs.
Preferably, the base portion has a shape which fits in a trough formed between transverse ribs extending across the end surface of the first profiled member, the base portion extending between respective inner surfaces of the ribs.
Conveniently, the base portion has a third upstanding portion which is fills a cavity formed in one of the profiled members or between the first and second profiled members.
Advantageously, the first and second profiled members are secured together by a fixing extending through the bore portions in the first and second upstanding portions, through holes in the first profiled member aligned with the bore portions and into the second profiled member.
Preferably, the fixing is received in hollow cavity in the second profiled member, the cavity being dimensioned so that the fixing is secured thereto.
Conveniently, the fixing is a self-tapping screw.
Other possible fixings comprise other types of screws, bolts, etc., the cavity in the second profiled member being pre-threaded or otherwise.
Conveniently, a head of the fixing is received in a recess in the second upstanding portion and surrounding the bore portion therein.
Preferably, the first and second profiled members have the same cross-section.
The first and second profiled members may be members of a window frame.
Further, the invention provides a method of forming a corner joint between first and second hollow profiled members, the method comprising the steps of shaping first and second lengths of hollow profiled material to fit together to form the joint, inserting a closure piece according to the invention into an end portion of the first profiled member, and securing the first and second members to each other, the base portion of the closure piece substantially closing the hollow interior to the first profiled member.
An embodiment of the invention will be described by way of example with reference to the drawings of this
specification, in which:
Figure 1 is top view of a closure piece according to the invention; Figure 2 is an end view of the closure piece of figure 1, seen in the direction of the arrow "A"; Figure 3 is a side view of the closure piece of figure 1, seen in the direction of the arrow "B"; Figure 4 is a side view of the closure piece of figure 1, seen in the direction opposite to that of arrow "B's'; Figure 5 is a section on the line V-V on figure 1; Figure 6 is a cross-section through the hollow profiled members which are to be joined together; Figure 7 shows a screw with which the closure piece can be used; Figure 8 is a view from the inside of a right-angled joint being formed between two hollow profiled members as shown in figure 6; Figure 9 corresponds to figure 8 but shows the joint from the outside and the members in engagement; Figure 10 shows in side view the joint of figures 8 and 9 after formation, and a closure piece of the invention being inserted into one of the profiled members; and Figure 11 corresponds to figure 9 but with the closure piece in place.
The closure piece shown in the drawings moulded in a single piece from a suitable plastics material.
Figure 1 shows that the closure piece comprises a base portion 10 which is about 2 mm in thickness and has a outer profile 12 which is chosen to match the cross-section of the hollow profiled members to be joined, except that the width in the direction of arrow B is slightly less than the width of the profiled members, for a reason which is explained below. The profile 12 comprises a major rectangular portion 14 and first and second extension portions 16, 18 at respective ends of one of the longer sides of the rectangular portion 14. The first extension portion 16 is smaller than the second portion 18 and is itself substantially rectangular in shape. The second, larger extension portion 18 has a rectangular shape, except for one outer corner which has a quadrant shape 20.
The base portion 10 has a first upstanding portion 30 extending along an axis perpendicular to the plane of the base portion 10, as can be seen in figures 2 to 5 of the drawings. The first upstanding portion 30 has a cross-section which is a snug fit within an interior cavity of the profiled members which are to be joined together. The first upstanding portion 30 is itself hollow and is divided transversely by a partition 32 which extends almost the full height of the upstanding portion 30. The partition has therethrough a bore 34 of circular cross-section, the axis of which is parallel to the plane of the base portion 10.
A second upstanding portion 40 extends from the base portion 10, its axis being parallel to that of the first portion 30. The second upstanding portion 40 has a rectangular cross-section and is solid apart from a bore 42 which is aligned with the bore 34 in the first upstanding portion. A cylindrical recess 44 surrounds the bore 42 on the outer surface of the second upstanding portion 40.
A third, hollow upstanding portion 50 also extends from the base portion 10, again parallel to the axes of the first and second upstanding portions 30, 40. The third portion has a generally pentagonal cross-section, as can best be seen in figure 1.
Figure 6 of the drawings shows the cross-section of the hollow profiled members 60 to be joined together.
Referring now to figure 6, it will be seen that the hollow profiled member has a cavity 62 of generally rectangular cross-section and shaped such that the first upstanding portion 30 of the closure piece is a snug fit therein. The hollow profiled member 60 has an outer surface 64 which is formed with a pair of parallel ribs 64a, 64b adjacent one longitudinal edge and a corresponding pair of ribs 66a, 66b adjacent the other longitudinal edge. The inner ribs 64a, 66a of each pair define a shallow trough 68 therebetween.
Internally and longitudinally of the cavity 62, the profile is formed with first and second cylindrical cavities 70a, 70b.
Figures 8 to 11 show the formation of a right-angled joint between two lengths 60a, 60b of the hollow profiled member shown in figure 6. It will be noted that one of the lengths 60a has been cut away at the end which is the lower end in figure 8 in order to receive an end portion of the other length 60b. When the lengths 60a, 60b fit together, they form a butt joint 80 shown in figure 10, rather than, for example, a mitred joint.
Referring specifically to figure 9 of the drawings, this shows the lengths 60a, 6Db joined at the butt joint 80 and from the outside of the right-angle formed between the two lengths.
Figure 10 of the drawings shows the closure piece of figure 1 about to be inserted into the hollow end portion of the length 6Db of hollow profiled member; figure 11 corresponds to figure 9 but with the closure piece inserted.
It will also be noted that the end of the second profiled member 6Db adjacent the joint is cut away slightly to provide a recess into which the base portion 10 of the closure piece can be received and lie flush with the end of the second profiled member 6Db, as shown in figure 11 of the drawings. This cutting away involves trimming of the ends of the ribs 64a, 64b, 66a, 66b and of the internal structure of the profiled member 6Db lying within its longitudinal side walls 64.
The closure piece is used by being inserted into the end of the second hollow profiled member 6Db, as shown in figure ID of the drawings. When inserted, the first upstanding portion 3D is received in the cavity 62, in which it is a snug fit. The second upstanding portion 40 is received in the trough 68, filling the space between the ribs 64a, 66a but not protruding outwardly therefrom. The gap between the first and second upstanding portions 3D, 4D receives an end portion of the outer wall of the cavity 62 in the first profiled member. It will also be seen in figure 9 that the base pcrtion lD of the closure piece closes the otherwise open end of the first profiled member, as can be seen in figures lD and 11. When inserted into the second profiled member in this way, the closure piece lies fully within the outer profile of the first profiled member and therefore does not protrude therefrom to interfere with the mounting of the window frame in, for example, an opening in which the window frame is to be mounted. The open interior the second profiled member 60b is thus closed by the support piece and provides a barrier to the ingress of cold or damp air, moisture, etc. The first portion of the first hollow profiled member is now placed at right angles to the second hollow profiled member to form a right-angled corner of a window frame, as shown in figure 8 of the drawings, and the two members brought together as shown in figure 9. In this relative orientation of the two pieces, a drill can be passed through the bore 42 in the second upstanding member 40 so that holes are formed in the outer and inner walls of the hollow cavity 62 of the first hollow profiled member. A self-tapping screw 74 of suitable length, as shown in figure 7 of the drawings, can now be passed through the bores 34, 42 in the first and second upstanding members 20, and into the end of the second hollow profiled member, the screw 76 being received in one of a pair of cylindrical cavities 70a, 70b in the second hollow profiled member.
The first upstanding portion 30 prevents distortion or collapse of the first profiled member under the loading of the screw 74.
It should be noted that, instead of the self-tapping screw 74, any other suitable fixing may be used, for example a bolt or other kind of screw. When the screw 74 is screwed fully home, its head 78 is received in the recess 44 in the second hollow profiled member and therefore does not protrude from the second upstanding portion 40.
The two hollow profiled members are thus secured together by the screw which is supported in the bores 34, 42 which, extending parallel to the base portion 10, ensure that the screw holds the two profiles together perpendicular to each other. Moreover, the hollow interiors of the members SOa, 60b are both closed in ingress of cold or damp air, moisture, etc. If desired, the joint can be made even more secure by the use of a suitable adhesive.
Use of the supporting piece according to the invention avoids entirely the use of welded, mitred corner joints in window frames constructed from the hollow profiled members.
A joint having an improved aesthetic appearance, closer to that of a wooden frame formed by conventional or traditional woodworking techniques, is thus formed.
