United States Patent C) 3,418,780 RANGE APPARATUS TRIM Robert F. Dalton and Eugene J. Barnett, Mansfield, Ollio,

assiguors to Westinghouse Electric Corporation, Pittsburgh, Pa., a corporation of Pennsylvania Filed Dec. 28, 1966, Ser. No. 605,245 4 Claims. (Cl. 52-627) ABSTRACT OF THE DISCLOSURE Trim structure for the edges of a door used on major appliances. The trim member is substantially L-shaped and has a pair of anges one of which engages the free edge of one wall of a front door panel and the other of which engages a lanced projection provided in a complementary wall of the panel and positioned slightly beyond the radiused area joining the complementary walls. The portions of the lanced projection which lie in the plane of the wall are curved toward the radiused area in order to position, fillets produced by enamel build-up, behind the forward edge of the lanced projection, enabling the trim structure flange to properly engage the projection.

This invention relates, in general, to cabinet and door constructions and, more particularly, to trim structure and means for mounting thereof to the cabinet or door construction.

The fastening of door or cabinet trim has for a long time been accomplished by the use of rivets, screws and molding or trim clips. The utilization of screws and rivets is objectionable because they detract from the overall appearance of the construction.

A special problem exists in using fasteners, particularly, at the radiused corners (i.e. where metal is bent to form complementary walls) of cabinet and door structures as herein contemplated. In order to limit the size of the trim structure it is necessary to locate holes therefor close to the radiused area which creates tooling problems and ywhich also induces chipping of the porcelain enamel in this area.

Accordingly, it is the general object of this invention to provide new and improved means for mounting trim structure to a cabinet or door construction.

It is a more particular object of this invention to provide new and improved means for attaching trim structure to a cabinet or a door, which means does not adversely affect the appearance of the assembled components,

Briefly, the above-cited objects are -accomplished by providing a substantially L-shaped trim member having a pair of flanges one of which engages the free edge of one wall of a door panel, for example, and the other of which engages a lanced projection provided in a complementary wall of the panel and positioned slightly beyond the radiused area joining the complementary walls.

The portions of the lanced projection which lie in the plane of the wall are curved toward the radiused area in order to position, fillets due to enamel build-up, under the trim member or behind the forward edge of the lanced projection. This enables the trim ange to properly engage the edge of the lanced tab even though lilleting occurs in the aforementioned area.

During installation of the trim member the lanced projections act as cams to effect flexing of the trim member one end of which is restrained through engagement of the free edge of the one wall with one of the trim flanges. The trim member is sufficiently resilient to snap back as the flange passes over the edge of the projection to thereby produce a snug fit which cannot be Ialtered without the aid of tools.

f. ICC

Other objects of the present invention will ybecome more apparent when considered in view of the following description and drawings in which:

FIGURE 1 is a perspective view of a cooking range incorporating the invention;

FIG. 2 is an enlarged cross-sectional view taken on the line Il-II of FIG. l;

FIG. 3 is a cross-sectional View taken on the line III--III of FIG. 2;

IFIG. 4 is a front View, partly broken away, of FIG. 2;

FIG. 5 is a rear view, partly broken away, of FIG. 2;

FIG. 6 is a cross-sectional view taken on the line VI-VI of FIG. 4, and L FIG. 7 is an enlarged fragmentary view illustrating a partially assembled trim member.

Referring now to the drawings, especially FIG. l, reference character 10 designates generally an electric cooking range comprising a panelled cabinet structure 11 including a top wall 12 supporting a plurality of surface heating units 13.

An oven liner, not shown, is supported within the cabinet structure 11, access to which is provided through a door structure 14 suitably hinged to the cabinet structure in a conventional manner, not shown. The door 14 comprises a panel structure generally indicated 16 (see FIG. 3) which includes a front panel 17 fand a rear panel 18. The front panel comprises a vertical wall 19 and a horizontal annular wall 21 which frames the vertical wall 19. Similarly, the rear panel 18 comprises a Vertical wall 22 formed by an annular wall 23 which fits within the annular wall 21 when the panel structure 16 is assembled 'by fastening means, not shown.

An elongated trim member 24 is provided for each vertical edge of the door structure 14. The trim member 24 has a substantially L-shaped configuration and is provided with a pair of of

lianges

26 and 27 which extend in opposite directions and in parallel planes as best illustrated in FIG. 3. The flange 27 has an L-shaped configuration thereby forming a recess 28 (see FIG. 7) with one of a pair of

complementary Walls

29 and 30 of the trim member 24. The free edge 32 of the vertical portion of the annular wall 21 is adapted to be received in the recess 28 and the ange 26 serves to engage the forward edges 33 of a pair of vertically spaced lanced projections 31 (only one being shown), see FIG. 3. The projections 31 are disposed in the front wall 19 which is complementary to the vertical portion of the annular wall 21.

To install the trim member 24, the ange 27 is fitted over the free edge 32 (see FIG. 7) and then the flange 26 is guided over the cam-like top surface of the projections 31 thereby stressing :or exing the trim member 24 until the flange 26 is moved beyond the forward edges 33. The trim member is sufficiently resilient to snap back to its pre-stressed condition thereby producing a snug fit thereof on the

walls

19 and 21. It will be apparent that movement of the trim member 24 about a vertical axis is prevented due to the attaching mechanism hereinabove described. Vertical displacement of the trim member is prevented by engagement of opposed end walls 37 of the trim member 24 with the horizontal portion of the annular Wall 21.

As can be seen from FIG. 4, portions 34 of the lanced projections 31 which lie in substantially the same plane on the front wall 19 are curved rearwardly of the edge 31 so that lleting, due to enamel build-up as indicated at 36, does not interfere with the engagement of the flange 26 with the edge 33.

Since numerous changes may be made in the abovedescribed apparatus and different embodiments of the invention may be made without departing from the spirit thereof, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. In combination, a door including panel structure and a removable trim member covering lat least a portion of said panel structure, and means attaching said trim member in said covering relationship comprising a pair of anges in said trim member, said panel structure including `at least two edges remote one from the other and adapted to engage said flanges, one of said edges comprising a lanced projection in said panel structure, the end of said lanced lprojection in the plane of the panel structure being curved away from the flange it engages to position `any llets, in that area due to enamel build-up, beneath the trim member.

2. Structure as specified in claim 1, wherein said panel structure comprises la front panel and a rear panel and said lanced projection is provided in said front panel.

3. Structure yas speciiied in claim 2, -wherein said anges lie in par-alle] planes and extend in opposite directions and said lanced projection extends in a direction substantially perpendicular to said plane.

4. Structure as specified in claim 3, wherein the other of said edges is in said front panel.
