Description

(54) DECORATED EXTRUDATES (71) We, SILENT CHANNEL PRO DUCtS LIMITED, a British company, of Ferrars Road, Huntingdon, Cambridgeshire, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to decorated extrudates.

The conventional method of constructing a frame for a window in a vehicle door is to spot weld a metal reinforcing or support channel to the inner and outer panels over three sides of the window opening and to spot weld reinforcing strips to the inner and outer panels over the lower and fourth side of the opening.

The punching of the openings in the inner and outer panels generally leaves sharp edges on the resulting flanges and the subsequent operation of spot welding leaves intermittent deformations in these flanges.

For these two reasons, it is desirable to cover or conceal the flanges.

For this reason flange finishers have been provided, which can mask these flanges and which are in the form of extrudates.

Hitherto, as a separate operation, an embellishment has sometimes been applied to the outer panel in a region near the flange finisher.

According to the present invention, there is provided a decorated extrudate intended, in use, to serve as a seal for a reciprocable sheet of glazing material and suitable for use on a motor vehicle, the decorated extrudate comprising an extrudate of which at least one part is intended to abut the sheet of glazing material and is covered by a flocked fibrous material, and, secured by adhesive to a part of the extrudate intended to fit over a lip of a motor vehicle, a decorative trim strip comprising a laminate of metallised polymeric film.

The present invention thus makes it possible, in a single operation, to finish the flange and to provide an attractive embellishment.

The decorated extrudate may be designed so as to define, in use, a channel for the reciprocable sheet, in addition to serving as a seal for the sheet.

The decorative trim may be, for example, one of the following: (a) a polyvinyl chloride (P.V.C.) extrusion covered with a laminate of metallised polyester film and coated with a clear vinyl polymer film; (b) as (a), but coated with a polyvinyl fluoride film (such as that known by the registered Trade Mark "Tedlar") instead of the clear vinyl polymer film; and (c) a laminate of metallised polyester film coated with Tedlar.

The extrudate may be, for example, styrene butadiene rubber (S.B.R.) Neoprene, ethylene propylene diene monomer (E.P.D.M.), or a blend of any two of these materials.

The flock fibres may be, for example, polyester or polyamid flock fibres, well known in themselves.

For a better understanding of the present invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which: Figure 1 is a side elevation of a car door; Figure 2 shows a cross-section through a support channel and adjacent edge regions of the inner and outer panels, taken along the line II - II in Figure 1; Figure 3 shows a cross-section through two opposing reinforcing strips and adjacent edge regions of the inner and outer panels, taken along the line III-III in Figure 1; Figure 4 shows the same cross-section of channel and panels as shown in Figure 2, but now provided with a flocked rubber glass run channel with a decorative strip; Figure 5 shows the same cross-section of reinforcing strips and panels as shown in Figure 3, but now provided with a flocked rubber waist seal with a decorative strip; Figure 6 shows, on an enlarged scale, a cross-section through the decorated, flocked rubber glass run channel shown in Figure 4, but in the "relaxed" state; and Figure 7 shows, on an enlarged scale, a cross-section through the decorated, flocked rubber waist seal shown in Figure 5, but in the "relaxed" state.

Three sides 1, 2 and 3 of an opening for a window (shown in Figure 1), are provided with a decorated, flocked rubber glass run channel located in a metal support channel between the inner and outer panels of the door.

The fourth side 4 of the opening is provided with reinforcing strips mounted on the inner and outer panels of the door, between which is a decorated, flocked rubber waist seal.

In Figure 2, between an inner panel part 5 and an outer panel part 6 is located a metal "U"-shaped support channel 7 held in place between the panel parts 5 and 6 by spot welds. The end flanges 8 and 9 formed by the free edges of the support channel 7 and the panel parts 5 and 6 have sharp edges.

In Figure 3, both the inner panel part 10 and the outer panel part 11 are provided with respective reinforcing strips 12 and 13 which are held in place by means of spot welds. As with the arrangement shown in Figure 2, the end flanges 14 and 15 formed by the free edges of the reinforcing strips 12 and 13 and panel parts 10 and 11 have sharp edges.

In Figure 4, a flocked rubber glass run channel 16 which forms part of an extrudate has been inserted into the support channel 7.

The channel 16 is provided with two shroud parts 17 and 18 which form other parts of the same extrudate and which together with the channel 16 define two recesses 19 and 20 into which the flanges 8 and 9 are inserted.

The channel 16 is also provided with two inwardly directed lips 21 and 22 which form further parts of the same extrudate and between which the sheet of glass will pass. The inner end surface 23 of the channel 16 and the opposing surfaces 24 and 25 of the lips 21 and 22 are intended to come into contact with the glass and are coated by an electrostatic method with polyester flock fibres.

The shroud part 18 is provided with a decorative trim strip 26 which comprises a laminate of metallised polymeric film and which is attached to the part 18 by means of an adhesive.

In Figure 5, two flocked rubber waist seals indicated generally by the reference numerals 27 and 28 are provided on the inner panel 10 and outer panel 11 respectively. The seal 27 is an extrudate and comprises a "U"shaped part 29 which defines a recess 30 into which is inserted the flange 14. The seal 27 is also provided with a lip 31 which comes into contact with the glass and the surface 32 of the lip 31 which comes into contact with the glass is coated with polyester flock fibres.

The seal 28 is an extrudate which is provided with a "U"-shaped shroud 33 which defines a recess 34 into which the flange 15 is inserted. A decorative trim strip 35 is secured by adhesive to the outer face of the shroud 33, which strip 35 has the same form as the strip 26.

The seal 28 is also provided with a lip 36 which is inserted around the lower free end of the reinforcing strip 13 and with a lip 37 which faces the lip 31 of the other seal 27.

Between the lip 37 and the shroud 33 is a channel 38 into which water running down the window will fall and be carried away.

That surface of the lip 37 facing the lip 31, and an adjacent surface of the body of the seal 28 is coated with flock fibres 39 as these surfaces will be in contact with the glass.

If desired, that face of the seal 27 facing the interior of the vehicle can be applied with a decorative trim strip similar or identical to the strip 35 on seal 28, as shown at 40 in Figure 5.

Similarly, the extrudate (16, 17 and 18) can optionally be provided on its shroud part 17 with a further decorative trim strip as shown at 41 in Figures 4 and 6, similar or identical to the decorative trim strip 26 and also attached by adhesive.

Figure 6 shows the extrudate (16, 17 and 18) in the "relaxed" position and Figure 7 shows the seal 28 in the "relaxed" position; the reference numerals used in Figures 6 and 7 denote the corresponding components similarly denoted in Figures 4 and 5.

The edge regions of the decorative trim strip may be "buried" in the relevant part of the extrudate, to prevent exposure of the adhesive to the rain.

WHAT WE CLAIM IS: 1. A decorated extrudate intended, in use, to serve as a seal for a reciprocable sheet of glazing material and suitable for use on a motor vehicle, the decorated extrudate comprising an extrudate of which at least one part is intended to abut the sheet of glazing material, and is covered by a flocked fibrous material, and, secured by adhesive to a part of the extrudate intended to fit over a lip of a motor vehicle, a decorative trim strip comprising a laminate of a metallised polymeric film.

2. A decorated extrudate according to claim 1, wherein the decorative trim strip is selected from: (a) a polyvinyl chloride (P.V.C.) extrusion covered with a laminate of metallised polyester film and coated with a clear vinyl polymer film; (b) a polyvinyl chloride extrusion covered
