DESCRIPTION OF PREFERRED EMBODIMENT OF THIS INVENTION Decorated panels for automobile interiors now usually include a decorative section, or segment, attached to a mounting panel.
An elevation side view of a decorated panel is shown in Fig. 1, wherein the decorative panel insert assembly 1, is attached to mounting panel stock 4, by the method and apparatus of this invention. The disclosure of apparatus, method, and product which follows, includes a movable platen die section 5, and stationary platen die section 6, which die sections are mounted in a conventional compression press. No further description will be made of the compression press, as such is well known.
In the following discussion the decorative panel insert assembly 1, includes the decorative surface of panel insert assembly 11, and backing of formed decorative insert 3. To further describe this invention, it is to be pointed out that the backing of formed decorative insert 3, of the decorative panel insert assembly 1, and mounting panel stock 4, are made of sheet stock of a thermoplastic, such as a polyolefin, preferably polypropylene, with fiber reinforcement such as wood fibers, glass fibers, or plastic fibers.
Such fiber reinforced material may have the following physical properties:
Impact (Joules) 8.0 Density range 0.95 - 1.07
Hardness (ASTM 02250) 82 (Shore A)
72 (Shore D)
Mod. of Elasticity 0.3 (G.Pa) (ASTM 0638-80)
Flexural strength (M Pa) 33 - 40 The backing 3, of formed decorative insert assembly, and the mounting panel stock 4 may have a thickness from about 0.04 to 0.4 inches (1.0 to 10. mm) more or less.
Fig. 1 shows a side elevation view of a complete decorated interior panel for a car door, while Fig. 2, is a cross section view of such decorated panel of this.
The assembly of decoration surface 11, of decorative panel insert assembly 1, and the backing 3 of the decorative assembly is of such form that includes down turned edge 9, of the decorative panel insert assembly 1. The decoration surface 11 is usually a type of woven or non-woven fabric, and is attached to the backing 3 by well known means such as hot pressing, or hot or cold adhesive. The backing 3 of the formed decorative panel insert assembly 1 of this invention can be a fiber or wood flour filled polyolefin thermoplastic such as polypropylene and as such is a conventional material.
The above decorative panel insert assembly 1 is formed in a die and press to any desired surface shape and to have a whole or partial perimeter of a down turned edge 9 and including pimple protrusions 2 on the inner or back edge and projecting flange edge 12, on the outer edge of down turned edge 9.
This formed assembly is then the decorative panel insert assembly 1 for subsequent attachment to mounting panel stock 4, which is the invention of this disclosure.
Mounting panel stock 4, is of thermoplastic, preferably polyolefin, such as polypropylene, filled with various fibers such as glass, or wood fibers. The decorative panel insert assembly l, formed with down turned edge 9, at ambient or room temperature is rigid, as indicated by the above data, and is attached to mounting panel stock 4, as described below. Mounting panel stock 4, is heated to softening at about 330° to 350° F. and subsequently laid on stationary female die section 6, having groove 8 on the mating surface, and the decorative panel insert assembly 1, placed on heat softened mounting panel stock 4, with the down turned edge 9 perimeter matching the perimeter of groove 8, and movable die section 5, having a shape conforming to the shape of the decorative panel insert assembly forces by action of
press closing the down turned edge 9 of the decorative panel insert assembly 1, to be embedded into mounting panel stock.
Referring now to Fig. 4, this illustrates mounting panel stock 4 between the die sections 5 and 6, and
Fig. 5 illustrates the formed mounting panel stock 4' with the down turned edge 9 of decorative panel insert assembly embedded into the mounting panel stock 4• and pimple protrusions 2 and projecting flange edge 12 on down turned edge 9, coined into the side walls of formed groove in mounting panel stock 4' .
Fig. 8 illustrates a magnified cross section view of partially formed mounting panel stock 4' ' , just prior to full close of the die sections. Fig. 7 illustrates the embedding of the decorative panel insert assembly 1 into the formed mounting panel 4' in groove 8, and the coining of pimple protrusions 2 and projecting flange edge into mounting panel stock wall 7, in groove 8. Pimple protrusions 2, on down turned edge 9 of decorated panel insert assembly 1 are preferably located on the back or concave side of the panel 1, while the projecting flange edge 12 is on the outer edge of down turned edge 9. The pimple protrusions 2 on the down turned edge 9 of decorative panel insert assembly 1 are for example, small button or pimple like protrusions of about one - eighth inch in diameter, and a height of about 0.0625 to about 0.125 inch or less, and spaced at about one half to about two inches intervals between the pimple protrusions, thus for a perimeter of about thirty inches there could be from twenty to forty pimple protrusions, preferably on or near the lower rim of the down turned edge 9, so that such pimple protrusions 2 are coined into side wall of mounting panel stock 4, in groove 8, and dimples 7 are formed by the protrusions 2 as the edge 9 of decorative panel insert assembly 1 is embedded in the groove
generated in mounting panel stock 4 on closing of the press mounted dies 5, 6.
The projecting flange edge 12 is best described as extending along the outer edge of lower rim of down turned.
To insure proper and tight fit of the decorative panel insert assembly 1, the groove 8 should be of such width to cause a close or interference fit of the down turned edge 9 of the decorative panel 1 into the mounting panel stock 4, and of such depth to have the pimple protrusions 2 and projecting flange edge 12 coin into the side wall of the groove generated in the mounting panel stock 4. The final embedment of down turned edge 9, into the mounting panel stock 4 is as shown in Fig.7, with the pimple protrusions 2 on the back edge of down turned edge 9, and projecting flange edge 12 on the outer edge down turned edge 9 of decorative panel insert assembly 1 coined into the groove wall of mounting panel stock 4, when platen dies 5 and 6 are forced together, by the press action and the dies at ambient or controlled temperature to solidify the heat softened mounting panel stock 4 with the decorated assembly 1, embedded therein.
The decorative overlay sheet 10, if desired can be a thermoplastic sheet such as polyvinyl adhered to the mounting panel stock 4. This decorative overlay sheet 10, may extend inward beyond groove 8, as shown in Fig. 4, and as noted in Figs. 6, 7, and 8, the decorative sheet 10, extends inward beyond the edge of groove 8, and is crimped into groove 8, along with the down turned edge 9, of decorative panel insert assembly.
In the method and apparatus described above, the contour of the completed decorated panel is controlled by the compression die configuration on die platens 5 and 6.
Referring now to Fig. 9, this shows the platen die sections 5 and 6 in1 "open" press position, with die section 5 mounted on the movable platen for example,
and die section 6 mounted on the stationary platen. The temperature of platen dies 5 and 6 are controlled in a conventional manner as required.
On attaching the decorative panel insert assembly 1, to the mounting panel stock 4, by action of the press to close the platen dies 5 and 6, the decorative panel insert assembly 1 is attached to the mounting panel stock 4, by embedment of the down turned edge 9 of the panel insert assembly 1 into the mounting panel stock 4 and the decorated panel with the decorated panel insert assembly 1 mounted therein, may be formed to a desired contour by the shape of the platen die sections 5 and 6 on closing of the press.
