Abstract
A plastic frame profile and seal arrangement 1 for a door or window comprises an integral channel 4b extending along its length and a hollow seal 3. Preferably, the profile 2 and seal 3 are co-extruded with the hollow seal closing off the neck portion 4a of the channel. As disclosed, the channel 4b is intended to receive excess waste material, or sprue, on welding.
Description
241 1 424 Improved Seal Arrangement The present invention relates to an
improved profile and seal arrangement, preferably a co-extruded profile and seal arrangement particularly suitable for use in window and door design and manufacture.
Seals are required in door and window manufacture between a frame member and an opening member, for example between a frame member and an opening window light or a door. Seals are also required between a frame member and any panel held against the frame member, for example glazing panels. Seals are present to prevent passage of air and water, and other elements, between frame members and opening members or other panels.
It is known to secure seals to frame members by suitable fixing means to provide a seal between a frame member and an opening member. It is also known to use glazing beads and substances such as putty to seal panels, such as glass panels, in position against a frame member.
Extrusion of profiles suitable for use as frame members in window and door manufacture from plastics materials leads to the need to fuse the profiles together to form a frame. The fusion techniques used require heat to be applied to the end portions of the profiles to soften the plastics material at these end portions. The end portions of the profiles are then bought together under pressure and the softened plastics material of the end portions adheres the profiles together as it cools.
The application of pressure to the softened plastics material causes some of this softened material to be forced out of the joint creating raised areas of waste material, known as a sprue, around the joint. With existing seal designs this sprue must be removed locally to allow the seal to fit in the groove around the welded corner. If excessive the sprue can also cause cracking or breakage of glass panels. The sprue can also be unsightly.
Accordingly there remains the need for a seal and profile arrangement that allows fusion of two such profiles creating minimal raised sprue around the joint.
Accordingly the present invention provides a profile and seal arrangement suitable for use in door or window manufacture comprising a plastics material profile having a seal secured thereto, wherein the profile is provided with an integral channel extending along its length and wherein the seal has a hollow cross section.
The provision of a seal of hollow cross section reduces the amount of material used to create the seal, which in turn reduces the amount of material from the seal present in the sprue thereby reducing the overall amount of sprue produced, on fusing two profiles together.
The provision of a channel in the profile ensures that at least part of the waste material expelled on fusion of two profiles is kept in the channel and the presence of sprue around the joint in areas where it can give rise to the problems discussed above is minimised.
The channel is preferably positioned below, and most preferably parallel with, the seal.
The channel may be an open channel or groove, for example a groove for receiving a seal. Where the groove is a seal groove the seal received therein only extends partially into the seal groove. A part of the seal groove is therefore unused and can accept some of the waste material expelled on fusion of two profiles.
The seal may be provided with an outwardly extending portion along its length to be received by the seal groove. The outwardly extending portion is preferably an extending open neck portion along its length to be received by the seal groove. The provision of an open neck portion further reduces the amount of material used to form the seal.
The hollow cross section of the seal may be substantially circular, square, triangular or any other suitable shape.
The profile is preferably made from any suitable thermoplastics material such as PVC-U. The seal is preferably made from a suitable thermoplastics material.
The profile and seal are preferably co-extruded as a profile and seal arrangement.
The present invention further provides a finished window or door, or all or part of a window frame or door frame comprising two or more profiles of the present invention.
An embodiment of the present invention will now be described in detail with reference to the drawing in which: Figure 1 shows a cross section through a co-extruded profile and seal arrangement of the present invention.
Figure 1 shows a co-extruded profile and seal arrangement 1 comprising a standard PVC-U profile 2 used in the manufacture of window frames or door frames having a seal member 3 co-extruded therewith.
The profile 2 is provided with a seal groove 4 extending along its length and extending downwards from the face 2a of the profile 2 to form an elongate channel in the profile 2. The seal groove 4 comprises a neck portion 4a, having a first width and depth, extending down from the face 2a of the profile 2 and along the length of the profile 2. The neck portion 4a opens into a channel 4b, of greater width and depth than the neck portion, which also extends along the length of the profile 2.
The seal member 3 is shaped to extend from one side 5 of the neck portion 4a of the seal groove to the other side 6 of the neck portion of the seal groove 4 forming a shape of hollow cross section above the seal groove 4. The seal member 3 is sized to extend only partially into the neck portion 4a of the seal groove 4 leaving the channel portion 4b of the seal groove unoccupied by any sealing material.
The co-extruded profile and seal arrangement 1 is made using appropriate co-extrusion tooling.
The co-extruded profile and seal arrangement 1 can be used in the manufacture of products such as window frames and door frames. The profile and seal arrangement 1 is cut to the desired lengths to make a particular frame. The ends of the profile and seal arrangement 1 to be secured together are heated to soften the plastics material of the profile and the material of the seal. The ends are then brought together under pressure in the desired configuration and the softened plastics material of the profile and the material of the seal effect joining of the two profile and seal arrangements on cooling.
At least some of the waste material generated around the joint, close to the seal, on application of pressure to the softened plastics material of the profile is received by the channel 4b of the seal groove 4 thus minimising the amount present in places around the joint where it can have detrimental effects on the product but is also difficult to access to remove.
