Abstract
An extruded flexible wedge- section flexible strip for insertion between a glass or other panel and a receiving channel in a puttyless glazing system not only has a notch 4 for snap engagement with a lip on the channel, but furthermore has an integral portion 5 hard and more rigid than the rest of the strip, forming a wall of that notch to limit extension of the strip, to stiffen the strip, and also to make it snap in place audibly, substantially irremovably and with greater certainty than a homogeneous strip. <IMAGE>
Description
SPECIFICATION
Extruded Elastomerics Components
This invention relates to extruded elastomeric components used for sealing purposes.
There are countless different sections used in sealing, involving some form of lip mounted in or on a rigid member. For example a lip section of natural or synthetic rubber, or of flexible plastics such as plasticized PVC, has its base received in a
Tee-section channel whilst its free lip portion bears against a glass or other surface. In puttyless glazing it is known to force a PVC section into the gap between the glass and the wall of a rigid channel in which it is received.
Such sections are necessarily flexible and are also generally capable of stretching. A serious problem that arises where unskilled or inexperienced people insert such strips is that they tend to stretch the strip slightly as it is inserted, and then cut it off flush at the end.
Within a short time the strip contracts to its natural length, leaving a gap. It is known to embed a substantially inextensible cord in such a strip with the object of preventing it stretching longitudinally whilst leaving its flexibility unimpaired. However problems arise in obtaining an effective bond between the cord and the rubber or plastics of the strip.
It is also known to make an extruded sealing strip of non-homogeneous construction, that is to say with a profile which has different characteristics in different regions. For example it may have a relatively hard and rigid base portion for engagement in the metal channel and a more flexible lip region to bear against the glass or other surface.
The aim of the invention is to provide further improvement in a composite glazing strip of this general kind. According to the invention we propose that a wedge-section flexible strip for insertion between a panel, e.g. a glass panel, and the wall of a channel in which the panel is received, should have an integral rigid substantially inextensible portion immediately adjacent to, and preferable forming part of the wall of, a notch or step by which the strip is retained in position in use.
This has several advantages. The most immediate one is that it makes the strip substantially inextensible, overcoming the drawback mentioned in the introduction above. A second advantage is that it stiffens the strip to some degree, whilst leaving its sealing lip flexible, and thereby makes it easier for the user to handle, and in particular easier to feed into a slot or channel of substantial length without buckling.
Third, the fact that the strip is made rigid adjacent to the step or notch by which it is held in place means that it is substantially incapable of being removed once it has been snapped into place.
Further, the hardness of this portion means that, unlike a homogeneous soft strip, it gives an audible click as it snaps into place, indicating that it has been correctly fitted.
Finally it is possible, by using different colours for the rigid portion, to employ a colour coding system to identify reliably and permanently a range of sizes and/or qualities or strip.
The invention will now be further described by way of example with reference to the accompanying drawing in which there is illustrated a section through a strip embodying the invention.
A continuous extruded glazing strip 1 of plasticized PVC has a cross-section of which a lower limb 2 is intended to be forced between the glass and the wall of a channel (not shown) whilst a lip 3 bears resiliently against the face of the glass. The strip is held in place by the engagement of a notch 4 over a bead formed at the mouth of the channel.
This section is known in itself. In the modification according to the invention, however, we provide an integral portion 5, relatively small in relation to the overall cross-section, this portion being of rigid hard unplasticized PVC. It will be seen that this narrow stripe 5 defines the lower wall of the notch 4 and it achieves all the advantages set out above.
The stripe 5 can readily be co-extruded in the appropriate colour together with the remainder of the strip, and so the cost of manufacture is substantially the same as that of the known homogeneous strip.
Claims
1. A wedge-section flexible strip for insertion between a panel and the wall of a channel in which the panel is received, in which the strip has a notch or step in one of its faces for retaining the strip in position in use, by engagement with a lip or step on the channel, and in which the strip has an integral semi-rigid substantially inextensible portion, harder than the main body of the strip, immediately adjacent to, and forming part of the wall of, the step or notch in the strip.
2. A strip according to claim 1 in which the main body of the strip is of plasticized PVC and the semi-rigid portion is of substantially unplasticized PVC.
3. A wedge-section flexible strip for insertion between a panel and the wall of a channel in which the panel is received, substantially as described with reference to accompanying drawing.

A wedge-section flexible strip for insertion between a panel and the wall of a channel in which the panel is received, in which the strip has a notch or step in one of its faces for retaining the strip in position in use, by engagement with a lip or step on the channel, and in which the strip has an integral semi-rigid substantially inextensible portion, harder than the main body of the strip, immediately adjacent to, and forming part of the wall of, the step or notch in the strip.
2. A strip according to claim 1 in which the main body of the strip is of plasticized PVC and the semi-rigid portion is of substantially unplasticized PVC.
3. A wedge-section flexible strip for insertion between a panel and the wall of a channel in which the panel is received, substantially as described with reference to accompanying drawing.
