BY ZVZW ATTORN E Y HANDLE ASSEMBLY BACKGROUND OF THE INVENTION Those vertically oriented handle assemblies typically I employed for the laiger appliances, such as refrigerators, are quite large both from the standpoint of utility in affording ready access to the same by children as well as adults and design considerations relative to the overall symmetry of the appliance closure. Two such handle assemblies are, of course, required for the upright refrigerator-freezer combination units. It goes without saying that these handle assemblies must be totally resistant to fracture and it is obviously desirable that the same blend aesthetically with the overall cabinetstructure. Those metal hand pulls having a chrome or stainless appearance have long been used for major appliances since they not only provide the requisite strength and decorative appearance but, also, give a utilitarian appearance of massive strength. Large stainless or chromed metal hand pulls are, of course, expensive; nevertheless, the use of those materials which even might be subject to fracture in normal use could not be tolerated if for no reason other than customer relations in the highly competitive major appliance field.

A composite handle structure utilizing low cost materials, such as cast plastic for example, to provide a major portion of the handle body and a relatively small high strength reinforcement would appear to present an attractive alternative. Such a handle structure must possess both the fracture resistant and decorative characteristics of prior handles and must not involve any appreciable increase in assembly time if substantial cost savings are to be realized. It is also highly desirable that a plurality of changeable trim structures be susceptible of usage with the same basic handle assembly to accommodate the various decorator colors.

Composite handle assemblies employing both frangible and infrangible components are well known as are composite handle assemblies utilizing separable hand pull and decorative subassemblies as exemplified by the respective disclosures in U.S. Pat. Nos. 2,407,763 and 3,393,423. Such prior art disclosures have not been concerned with the objectives of this invention which include the use of a relatively small reinforcing insert as compared to the overall size of the handle assembly; the use of the reinforcing insert, itself, to support an otherwise flaccid trim structure; and the necessary positionment of the reinforcing insert upon a fully exposed portion of the ha'ndpull so that the decorative trim will be prominently displayed. The problems presented in the attainment of these objectives include isolation of the frangible component from excessive pull forces, ready assembly and disassembly of the insert with respect to the remainder of the assembly and the avoidance of fracture load iinpositions upon the frangible component as a function of the application of the closure mounting fasteners which must, necessarily,

provide a rigid handle mounting structure.

SUMMARY OF THE INVENTION outwardly opening recess and the mounting brackets to secure the plastic body to a closure. The bearing surfaces of the clips are large in comparison to the heads of the threaded fasteners so that they act as washers to spread the compressive load, exerted by the fasteners, over a substantial area of the frangible plastic body. The clips serve a secondary function as the reinforcing insert retainingmeans whose retaining function is independent of the closure mounting fasteners. Each clip consists of a first flange which coacts with the closure mounting fastener to spread the compressive loads and a second flange configured to provide a positive retention of the insert with the use of a single additional fastener.

The insert may comprise any desired high strength material such as rolled steel, for example. A desired trim in the form of a normally flaccid sheet material is laminated to the insert making it unnecessary to chrome or otherwise surface finish the reinforcing insert. The sheet material trim is normally a decorative vinyl having a desired surface appearance which may include various colors, a wood grain finish, or the like. The laminated insert is a generally hollow body which is fitted into the recess in the plastic body and telescoped over one of the clip retaining flanges while a projection in the form of a nut clip projects from the insert at the other end thereof to coact with the other insert retaining-flange to receive a threaded fastener therethrough.

The completed assembly this presents an infrangible framework opposing pull forces applied to the plastic body which framework comprises the appliance closure, the closure fasteners, the clips and the reinforcing insert. The insert may be readily exchanged to provide a different trim by removing a single fastener while leaving the closure fasteners in place.

DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective of a handle assembly, including a decorative backing member, of a handle assembly constructed in accordance with the invention;

FIG.2 is longitudinal sectional view of the handle assembly as applied to' a closure member; and

FIG. 3 is top elevational view of the handle assembly as mounted on a closure member but with the infrangible insert removed to disclose underlying structure.

DESCRIPTION OF THE PREFERRED EMBODIMENT An exploded perspective of a handle assembly 10 embodying the present invention is illustrated in FIG. 1 and includes a chrome plated plastic body 12, a pair of

mounting clips

14, 15, a pair of closure mounting fasteners 18, a rolled steel reinforcing insert 20, a flaccid sheet material trim blank 22 and an insert mounting fastener 24. The'plastic body 12 is cast with integral mounting brackets 26 at opposite ends thereof defining a hand grip portion 28 therebetween which hand grip portion includes an outwardly opening recess 30 having a generally channel shape defined by base 32 and side walls 34. The ends of recess 30 are delimited by an imperforate end wall 36 and an apertured end wall 38.

Each

mounting clip

14, 15 includes an apertured

base mounting flange

40, 42, the surface area of which is large in comparison to the heads of the closure mounting fasteners 18. The heads of fasteners 18 are retained by the respective

base mounting flanges

40, 42 acting in the nature of washers to spread the compressive loads applied to frangible body 12 by fasteners 18 extending through mounting openings 44 in mounting brackets 26 and into retaining engagement with a closure member 46.

Each mounting clip l4, 15 also includes an

insert retaining flange

48, 50 which, respectively, extend in closely spaced relation to the base 32 of recess 30 and the inner wall of apertured end wall 38 when the clips are assembled with the plastic body 12 and closure mounting fasteners 18 as indicated in FIG. 3. Insert retaining flange 50 is provided with an aperture adapted to align with the aperture in end wall 38 and an aperture in an end wall 52 provided at one end of the hollow reinforcing insert 20 when the parts are assembled as shown in FIG. 2. The other end of insert 20 is cut away along a lower edge 54 thereof a distance approximately equal to the length of insert retaining flange 48.

A pair of fastener retaining nuts 56 engageable with the threaded ends of fasteners 18 may be employed to maintain the assembled relationship of parts prior to mounting the handle assembly on a closure. These same nuts 56 may be subsequently used to secure the handle assembly to a closure as shown in FIG. 2.

A decorative back panel 58 which may comprise a vinyl laminated, chromed plastic body may be mounted conjointly with the handle assembly, if desired.

Following lamination of sheet material trim 22 with insert 20 and the initial assembly of parts illustrated in FIG. 3; the open end of insert 20, opposite end wall 52, is telescoped over insert retaining flange 48 of clip 14 with the lower wall 43 of insert 20 received within the space between the retaining flange 48 and base 32 of recess 30. Thereafter, the other end of insert 20 is pressed into recess 30 with the end wall 52 on insert 20 entering the space defined between the plastic body end wall 38 and retaining flange 50. The insertion of an insert retaining fastener 24 through the aligned apertures in

end walls

38 and 52 and retaining flange 50 completes the assembly as shown in FIG. 2.

Inasmuch as hand grip portion 28 is closely backed by the infrangible insert, pull forces applied thereto are transmitted directly to the closure via insert 20,

clips

14, 15, fasteners 18 and nuts 56.

The insert 20 is thus seen to perform the dual functions of isolating the frangible body member from fracture forces and providing a rigid support for an otherwise flaccid trim structure.
