Abstract
A channel-shaped sealing strip for vehicle door openings has a gripping section 5 incorporating a metal carrier 6 covered in flexible covering material 12 which additionally defines longitudinally extending gripping lips 14. Between sharp bends or corners, the gripping section 5 is provided with additional reinforcing members 20 which seat in the base of the channel, and are made of stiff but pliable metal. <IMAGE>
Description
SPECIFICATION
Improvements in and relating to trimming or sealing strips
The invention relates to channel-shaped strips such as for trimming an edge flange and for sealing purposes. Such strips may, for example, be used in motor vehicles body constructions for trimming edge flanges running around door openings, and luggage compartment openings, and for supporting seals therearound against which a door of the opening closes.
According to the invention, there is provided a channel-shaped trimming or sealing strip in combination with a separate, relatively straight, reinforcing member which is fitted within the channel and which is stiff but sufficiently pliable to enable it to be bent slightly, with the strip, to hold the strip in a slight curve.
According to the invention, there is also provided a channel-shaped trimming or sealing strip in the form of a loop which is pre-formed to suit a particular vehicle body opening, comprising a plurality of lengths of reinforcing member respectively positioned within the channel in parts of the length of the strip between the positions where sharp bend or corners are required in the loop, the lengths of reinforcing member being stiff but sufficiently pliable to enable them to be bent slightly, with the strip, to hold the said parts of the strip in a slight curve, the strip being completely free of said reinforcing member at each of the sharp bends or curves.
Trimming and sealing strips embodying the invention will now be described by way of example and with reference to the accompanying diagrammatic drawings in which:
Figure 1 is a perspective view, partly broken away, of part of one of the strips;
Figure 2 is a perspective view, partly broken away, showing the construction of the strip near a sharp bend or corner; and
Figure 3 is a cross-section on the line Ill-Ill of
Figure 1 but additionally showing an attached sealing section.
The strip shown in the Figures is for fitting to an edge flange around the door opening of a motor vehicle body. It is in the form of a channel-shaped gripping portion 5 including a metal carrier 6 which has a plastics, rubber or similar flexible covering 12 defining inwardly projecting lips 14.
A sealing portion 1 6 (shown in Fig. 3 only), made of cellular rubber for example, may be attached to the gripping portion 5. In use, the gripping portion 5 grips onto an edge flange around the door opening and supports the sealing section 1 6 so that the latter extends around the door opening and provides a draught and weatherproof seal onto which the door closes in use. In the absence of the sealing portion 1 6, the gripping portion 5 performs primarily a trimming or protective function.
The lips 14 form seals against the sides of the flange and also help retention of the gripping portion of the flange. There may be equal numbers
of lips 14 on each side of the channel, and the lips
can be of the same size.
The sealing portion 16 may be adhesively
secured to the plastics covering 12. Instead,
however, it is possible to make the covering 1 2 and the sealing portion 1 6 of such compatible
material that they can be extruded by means of a
dual extruding process, so as to have the desired different hardnesses.
The carrier 6 may take any suitable form. For
example, it may consist of U-shaped elements
arranged side-by-side to define a channel and
either completely disconnected from each other or
interconnected. Advantageously however, it may
take the form shown in British Patent No.
1492061, in British Patent No. 1 598683, or in
published British Patent Application No.
2032500. These each show a carrier where the U
shaped elements are connected together by
inclined links which give the carrier longitudinal
dimensional stability so as to enable it to resist
stretching or shrinkage, but yet enable the carrier,
and thus the strip, to be compressed lengthwise to
a slight extent.
The strip is advantageously made up into a loop
or ring to suit a particular vehicle door opening.
Such a door opening will of course have sharp
bends or corners with relatively straight portions
extending between them. However, with modern vehicle bodies it is unlikely that the relatively straight portions are in fact absolutely straight: they will normally be slightly curved and may be curved in more than the plane. Such portions are
referred to below as "the intermediate portions".
As shown in the Figures, the strip is provided with reinforcing members 20, but only along those lengths of the strip which are to be fitted to the intermediate portions of the vehicle door opening.
The portions of the strip at the sharp bends or curves (see Fig. 2 where such a sharp bend is illustrated) are not provided with any such reinforcing member 20.
The reinforcing members 20 are made of metal or any suitable material and are of shallow asymmetric channel shape in cross-section. The width across the channel of each reinforcing member is such that it is a relatively tight fit in the inside of the base of the gripping portion 5 so as to enable it to be held therein-merely by friction. However, as it is positioned between the base of the channel of the gripping portion and the innermost gripping lips 14, it will additionally be prevented by the lips from falling out.
However, if desired, the reinforcing members may be additionally held in position as by adhesive.
The reinforcing members 20 may be provided with suitable coatings to prevent corrosion.
The reinforcing members 20 are relatively stiff and thus hold relatively stiffly the lengths of the sealing strip intended to be fitted to the intermediate portions of the door opening.
However, the members 20 are arranged to be sufficiently pliable to enable them to be bent or curved slightly by the fitter when he is assembling the strip to the vehicle body opening. In this way, he can shape or form the sealing strip to match any slight curves of the intermediate portions of the door opening (in any plane), and the reinforcing members will thereafter retain the sealing Strip in that shape.
The fact that the sealing strip is completely free of the reinforcing members 20 at the positions where sharp bends or curves are required enables the fitter to more easily fit the sealing strip into such sharp bends or curves. Furthermore, it has the advantage that the loop or frame can be more easily "folded up" for storage or transport, before fitting to the vehicle body.
If the metal carrier 6 has the form illustrated in the above-mentioned British Patents or abovementioned British Application, the strip has the advantage that, even though it is provided with the reinforcing members 20, it can still be compressed lengthwise to a slight extent so as to enable its length to be adjusted slightly to take account of tolerances in manufacture.
Although the arrangement is particularly advantageous where the sealing strip is in the form of a closed loop or frame, it is not essential, and it may be applied to the case where this is not so.
It will be appreciated that the arrangement may also be applied where the sealing strip is to be fitted around the opening of a luggage compartment of a vehicle body.
Claims (9)
