HANDLE ASSEMBLY
Abstract
A handle assembly includes a relatively small infrangible insert
which performs the dual functions of isolating a relatively large
frangible hand pull structure from excessive pull forces and
providing support for a decorative, flaccid trim structure. A pair
of insert mounting clips coacting among the usual closure mounting
fasteners, the frangible hand pull and the insert permit the insert
to be assembled with the hand pull with a single insert mounting
fastener, and additionally, spread the compressive loads applied to
the frangible hand pull by the closure mounting fasteners.

Description
BACKGROUND OF THE INVENTION
Those vertically oriented handle assemblies typically employed for
the larger 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 cabinet structure. 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 hand pull 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
impositions 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
A chrome plated plastic body having substantially the overall
dimensions of a desired handle assembly is cast or otherwise formed
with an outwardly opening recess on the side thereof opposite the
mounting brackets. The usual headed closure mounting fasteners are
then inserted through a pair of metal clips, the base of the
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
retaining means 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 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 14, 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.
