' 'III'IAVIII" 1 DECORATIVE TRIM STRIP MOUNTING MEANS BACKGROUND OF THE INVENTION In the major appliance industry, and particularly in the domestic rangeindustry, it is conventional to provide a number of different models from the relatively simple and inexpensive models up to the high end of the line models which would have all of the important performance and design features supplied therewith. The models between the low end and the high end of the line would have increasingly more performance and appearance design features from the next lower model. One method employed for improving the appearance design features is by adding decorative trim strips to present a more elegant and finished appearance. Such decorative trim strips are frequently found on the opposing side edges of an oven door or along the two side edges of the cooktop of a range.

Many times in the past, such trim strips were held to the supporting structure by special spring clips which required special mounting holes punched into the supporting structure. Such mounting holes require a separate step in the manufacturing process, and they also require a double inventory of the unperforated design.

without trim strips and the perforated design for mounting the trim strips. This tends to complicate the parts inventory problem in the factory.

The principle object of the present invention is to provide a mounting means for decorative trim strips on a supporting structure which does not require special mounting slots so that the same supporting structure can be used for either the trimmed or the untrimmed models. 7

A further object of the present invention is to provide special compressible spring clips for holding a decorative trim strip to a supporting structure.

A still further object of the present invention is to provide a supporting structure with an outer panel having a raised ledge cooperative with a decorative trim strip and compressible spring clips whereby the raised ledge serves to enhance the appearance of an untrimmed panel while also serving as part of the mounting means for the trim strip on a trimmed panel.

SUMMARY OF THE INVENTION The present invention, in accordance witli'one form thereof, relates to a supporting structure and means for mounting a decorative trim strip thereon without having to form holes in the supporting structure. The supporting structure has anouter panel with a peripheral flange and a raised ledge. The elongated decorative trim strip is of angular configuration with inwardly folded re-entrant edges for assembly with the compressible spring means and fitted over the raised ledge and bearing against the side thereof to' form a tight fit. Compressible spring means are provided to bear at one end against the interior of the raised ledge and at the other end to engage the adjacent edge of the trim strip.

BRIEF DESCRIPTION OF THE DRAWINGS This invention will be better understood from the following description taken in conjunction with the accompanying drawings and its scope will be pointed out in the appended claims.

FIG. 1 is a front elevation view of a slide-in range which is adapted to be mounted in a cutout opening in a run of kitchen base cabinets which are not shown.

FIG. 2 is'a fragmentary isometric view on an enlarged scale that is exploded to show important details of the oven door at one corner thereof.

FIG. 3 is a fragmentary, transverse cross sectional view on a still larger scale of one side of the oven door to show a decorative trim strip engaged over the raised ledge on the edge of the outer panel and a spring clip holding the trim strip in place.

FIG. 4 is a transverse, cross sectional, elevational view on a reduced scale showing the oven door separated from the oven to depict the details of the fastening means between the inner and Outer door panels.

DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now to a consideration of the drawings, and in particular to the front elevational view of FIG. 1, there is shown, as is conventional in this art, a domestic range 10 that has a horizontal cooktop 12 that would be generally flush or slightly depressed below a kitchen countertop. A baking and broiling oven 14 is located beneath the cooktop and there is a backsplash l6 arranged along the back edge of the cooktop 12 and rising vertically therefrom to-support a control panel 17 with two

oven controls

18 and 20. The control 18 might be an electric selector switch or a gas valve, and control 20 would be an oven thermostat for controlling the degree of temperature within the oven cooking cavity. Additional control means would have to be included for either the electric surface heating elements or gas surface burners 22.

The front of the oven 14 is supplied with an oven door 25 of generally sheet metal construction which is adapted to be hinged adjacent its bottom edge 27 so that it is opened by grasping the upper door handle 29 and pulling the door downwardly and outwardly into a generally horizontal, fully open position for gaining access to the interior of the oven cooking cavity.

A more detailed showing of the oven door 25 is found in FIG. 4. The sheet metal construction of the door includes an outer door panel 31 of flat pan configuration having a peripheral flange 33 extending rearwardly therefrom. There is also an inner door liner 35 that has a peripheral flange 37 extending forwardly therefrom and which is adapted to telescope within the peripheral flange 33 of the outer door panel 31. The inner door liner 35 alsohas a centrally located embossment 39 of rectangular plug-like configuration which is adapted to fit within the front opening of the oven cooking cavity in a close-fitting relationship. Within this embossment is placed a heavy layer 41 of thermal insulating material such as fibre glass or the like which is held in place by an insulation guard 43 that is fastened on the inside of the inner door panel 35. The lower portion of the peripheral flange 33 of the outer door panel 31 has a series of vertical lanced tabs 45 which are adapted to fit into mating slots (not shown) in the lower portion of the peripheral flange 37 of the inner door liner 35.

As mentioned previously, the upper portion of the outer door panel is provided with a door handle 29 of extended width as is seen in FIG. 1. This handle 29 has two support posts 47 which are spaced apart to constitute the end portions of the handle. Each post of the handle accommodates an interior fastening screw 49 that extends through a suitable opening in the outer door panel 31 and assembles the handle in place. A mounting bracket 51 is also held down by each fastening screw 49. This bracket extends rearwardly from the handle connection for cooperation with a second exposed fastening screw 53 that extends first through an opening in the inner door liner 35 and into an opening in the bracket member. Thus, it can be seen that the bottom portion of the inner door liner 35 is held to the outer door panel by the interlocking tabs 45 and mating slots (not shown), while the top portions of these two panels are fastened together by the two pairs of fastening screws 49 and 53 that cooperate with the door handle 29. Y

Turning now to a consideration of FIG. 2, the outer door panel 31 is shown with a raised ledge 57 that is shown extending around the peripheral edge of the front surface of this outer door panel. Such a raised ledge can also be formed by depressing the central portion of the outer panel 31. Such a raised ledge 57 gives the outer panel 31 more rigidity, and it also tends to frame the door and provide a shadow box appearance which tends to enhance its appearance.

FIG. 3 is a view taken transverse of one edge of the oven door 25 on the line 3-3 of FIG. 2, but on an enlarged scale. The telescoped relation of the flange 37 of-the inner door liner 35 to the flange 33 of the outer door panel 31 is clearly illustrated. Located between the

telescoped flanges

33 and 37 is a compressible spring clip 60 of thin spring material of a width of about one-half inch. The clip 60 has a central compressive section 62 of generally transverse, hair-pin configuration and two oppositely directed

ends

64 and 66 which are offset from each other and generally parallel to the other. The opposite end 66 of the clip bears against the inner-surface of the raised ledge 57 of the outer door panel 31 adjacent the innermost edge of the ledge so as to stabilize the clip and prevent it from slipping out of position or shaking loose during movement. Each side of the door has about three spring clips 60 assembled therewith.

A decorative trim strip 70 is adapted to be fitted to the sides of the outer door panel 31. This trim strip 70 is of right angular configuration having an outer or front flange 72 and a generally perpendicular side flange 74. Each trim strip 70 is elongated to extend for substantially the entire side of the door such that there are four trim strips 70 shown in FIG. 1. It will be understood that a modification of this invention would be to include the trim strip 70 on only the two opposing sides of the oven door 25 rather than on all four sides as shown in FIG. 1. Each

flange

72 and 74 of the trim strip 70 has its free edge folded inwardly at a re-entrant angle, as fold 76 of flange 72, and fold 78 of flange 74.

To assemble the trim strip 70 to the outer door panel 31, the fold 76 of the trim strip is first engaged behind the raised ledge 57, the trim strip 70 is fitted against the side of the panel and the spring clips 60 are assembled in place, all before the inner door liner 35 is fastened to the outer door panel.

While the present invention is shown as applied to the sides of an oven door, it will be understood by those skilled in this art that the same invention might be applied to the side edges of a cooktop 12 wherein, as shown in FIG. 3, the outer door panel 31 might be represented by the cooktop 12 and the inner door liner 35 of FIG. 3 might constitute the spill guard located beneath the cooktop, and the raised ledge 57 could constitute the side edge of the cooktop 12 rather than the side edge of the door 25.

Modifications of this invention will occur to those skilled in this art, therefore, it is to be understood that this invention is not limited to the particular embodiments disclosed, but that it is intended to cover all modifications which are within the true spirit and scope of this invention as claimed.
