Molding for rectanguLar panels, such as vanity tops, cabillet doors, picture mountings and l:he like màde from strips of metal 7~,j' ha~ing a channel-like cross ~sec~ion are well known ill the art.
,~ The Spertus Patent No. 3,388,491 is an example of this type of i~ molding wherein a single ~etal strip is bent into the rectangular '~ shape of the panel to be enclosed, having first been mitred to bend ~' at the corners of the panel. Fx~rudecl molding such as shown in ,~, the Kulicke Patent NOn 27777,232 and in the Peach Patent No.
`~. 3,060,606 is also known. The Kulicke device has a hook shaped cross section adapted to engage a slot on the backside of ~ panel~
abut the edge of the panel and ext~nd a flat portion over the edge surface of ~he front face of the panel. Peach is a U-s~aped extrusion I ~
,~
", ~ -, -~97~ 5 which depends on deflection of one of the legs of the U-shaped aevice to sandwich a panel there between. E:ach of these prior art moldings performs essentially khe same function, i.e. to encase a panel with a plain substantially flat rectangular frame. None of these prior art moldings relate to decorative paneling strips with -the three dimen-sional look, nor to the problems required to be solved in securely attaching such decorative pane:L strips to panels.
In accordance with the present invention, there is provided a contoured decorative trim strip for a panel core hav.ing flat parallel front and back surfaces, straight side surfaces, and detents on the front surfaces parallel to the side surfaces comprising: an elongated extrusion having one straight flat side portion adapted to abut ~ p Q~
against a.straight side surface of the ~m~; the flat side portion having a first rear rib extending therefrom to engage the back surface of the panel; a second front rib parallel to and spaced apart from the first rib and extend-ing from the flat side portion to engage the front surface of the panel; a flexible decorative generally convex contoured front portion extending from the front edge of the flat side portion laterally thereof to project over the front surface of the core to define therewith an enclosed space therebetween; finger means projecting back-wardly from the decorative contoured front portion remote from the front edge adapted to engage a panel detent when the contoured portion is flexed and thereby extended against the panel; the strip being mitred at opposite ends to align with like adjacent mitred strips when also flexed into detent engagement with the panel.
jrr:! - 2 ~7~)~45 It is therefore an object of this invention to provide a novel inexpensive but attractive decorative trim strip for picture frames, cabinet doors, and similar such multi-sided panels requiring so called tllree dimen-sional decorative framing.
It is another object of this invention to pro- ~;
vide a novel decorative trim strip for panel cores which can be assembled and disassembled without use of special tools.
It is yet another object of this invention to provide a novel decorative trim strip suitable for profess-- ~
ional application by cabinet makers and picture framers ~ ;
yet within the skill of amateur craftsmen.
It is still another object of this invention to provide a novel decorative trim strip which may be easily snapped onto a panel core to make a mitred fit of profess-ional caliber with adjacent trim strips.
It is a further object of this invention to provide novel decorative trim strips which may be readily snapped onto a panel core in a manner which stabili~es a mitred joint between strips.

FIGURE 9 is a front elevational view of a panel core showing trim strip rib detents adapted to engage contoured decorative paneling trim strip edges;
FIGURE 10 is a plan view of a mitre cutting fixture showing a trim strip being mitred in accordance with the inven~ion; and, FIGURE 11 is a sectional view taken along the line 11-11 of FIGURE 10 showing the unflexed and flexed cross sections of the trim strip before and after engagement with the detent groove of the mitring~fixture.
Referring now to the drawings in greater specificity, a pre-ferred embodiment of the in~ention is shown in FIGIJRES 1 and 3 com- ;
pr~sing a panel core member 10, having flat parallel front and back , ~urfaces 12 and 14 respectively; straight sides 16; and detent grooves 13 scored on the front face 12 and parallel to sides 16. An elongated transversely flexible plastic extruded trim strip 20 has one straight flat portion 22 adapted to abut against a straight core side 16. Fro1nt ~d back edges 24 and 26 respectively of flat portion 22 are straight a~d parallel. A rib 28 extends from front edge ~4 to bear against front surace 12~ A rib 30 extends from back edge 26 to bear against _ 4 _ .

back surface 14. The distance between ribs 28 and 30 is equal to or preferably slightly less than the distance between core surfaces 12 and 14 so as to provide a snug fit between the core 10 and the ribs 28 and 30. A decorative contoured front portion 32 extends upwardly from edge 24 and then across the front surface 12 of core 10 to edge 34. Extending downwardly from edge 34 is detent engaging portion 36 terminating in a detent engaging finger 38 which engages detent groove 18. In the preferred embodiment, shown enlarged in FIGURE 4, outside edge 42 of detent groove 18 is met by external edge 44 of finger 339 or preferably, as shown in FIGURE 6, finger edge 44 slightly overlaps detent groove edge 42 to conceal the groove 18. ~n lieu of the groove detent 18, a rib 41, FIGURE 5 may be secured to front surface 12, to be engaged by edge 43 of finger 38. In either event, extremity 43 of finger 38 pressure engages detent groove wall.surface 45, FIGURE 4, or detent rib surface 47, FIGURE 5. For finger 38 to be brought into detent :
engagement, trim strip 20 is transversely extended by flexing to make snap-in engagement with detent groove 18 or rib 41. If detent ribs 41 are used, they, of course, would be positioned, such as shown in FIGURE 9, so as not to interfere with.trim strip ribs 28.
FIGURE 11 illustrates the flexed and unflexed cross sectional con-figuration of the trim strip 20.
It will be noted that a space 46 is intermediate contoured portion 32 and front surface 12, FIGURE 3, to provide the three dimensional look valued in decora~ive panels. To emphasize the sculptured effect, co~toured portion 32 may be e~ended downwardly ~o ma~e contact wi~h front surface 12, as shown i~ FIGVRE 6~ By bringing co~toured portion 32 into pressure contact with surface 12, ~ib ~8 m~y be dispensed w~th. In FIGURE 77 pressure contact is main- .
tained w~h fron~ surface 12 by rib 48 extending dow~ from the , ~7~45 lowermost point 50 of contoured portion 32.
Whereas the embodiments of FI~URES 1 through 7 are par~
ticularly suitable for decorative panels, the embodiment of FIGURE 8 is particularly adapted for picture framlng. The trim strip of FIGURE 8 is substantially as shown and described with reference to FIGURES 1 through 7, however, a third rib 52 is pro-vided to 13terally extend from detent engaging po-rtion 36 to grip a picture 54 and/or its mat 56 snugly between rib 52 and core front surface 12.
The distance between core side 16 and detent groove surface 45 is greater than the width of trim strip 20 measured from f].at por-t~on 22 to finger extremity 43 in its normal unflexed stat . This .3relationship is illustrated in another context in FIGURE -~ showing the trim strip flexed in solid lines and unflexed in broken lines.
Accordingly, in order to snap engage finger 38 with groove 18 it is necessary to laterally extend or flex the trim strip until engage-ment can be made. There are a wide range of plastics well known to those skilled in the art which may be selected to provide a trim strip reasonably stiff yet sufficiently flexible for the pur-pose of this inNention. An important basis of selection is that ~ -the plastic have a sufficiently 8atisfactory modulus of elasticity that the trim strip is maintained in tension be~ween the core side 16 and the groove wall surface 45. The same dimensional relation-ships also exist between the core 10 and the trim strip 20 with the use of a rib detent 41 wherein the same resultant dynamic re lationship exists therebetween.
¦ In order to obtain a mitre fit of professional quality be~ween adjacen~ trim strips, the strip must be cut in its flexed state.
For this purpose a fixture 60, FIGURES 10 and 11, includes si~nulated core side 62, simulated detent groove 63 and wall 64 and slmulated .

~ 7~945 core front and back surfaces 66 and 68 respectively, which have the same dimensions and dimensional relationships as core side 16 9 detent groove 18, wall ~5 and core front and back surfaces 12 and 140 Mitre cutting blade guides 70 and 72 hold mitre blade 74 in proper cutting alignment. After the trim strip 20 has been cut under tension as shown in FIGURE 10, removal and re~engagement with an actual core results in perfect alignment between trim strip abutting mitred edges.
It is believed that the invention, its mode of fabrication and assembly and its advantages will be understood rom the foregoing description, and it i5 further believed tha~ while several pre-ferred embodiments of the invention have been shown and described for illustrative purposes, the structural details are nevertheless capable of variation within the intent and scope of the invention as deflned in the appended claims.
