Abstract
A refrigerator handle assembly includes a base plate which is initially attached to the face of the refrigerator, such as through the use of screws or the like. The base plate includes tapered surfaces, preferably at longitudinally spaced positions. Once the base plate is secured, a portion of the handle is placed over the base plate and slid relative to the base plate whereupon the tapered surfaces coact with structure on the handle such that an interference fit is developed to draw the handle tight to the face of the door. With the handle in this position, one or more mechanical fasteners are driven into a body portion of the handle from a back side of the door.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to the art of refrigerators and, more particularly, to a mounting arrangement for a handle on a refrigerator.
2. Discussion of the Prior Art
Conventional handle arrangements for refrigerators are formed from multiple pieces, including a handle frame and a handle piece having a gripping portion. Such a handle is typically mounted to a refrigerator cabinet utilizing screws which extend through the handle piece and frame, clamping the overall handle to a panel of the refrigerator cabinet. Once the handle is in place, a cover is inserted over the screw, with the cover extending only over the area of the screws or along substantially the entire length of the handle. In general, this known handle mounting arrangement is rather hard to assemble and often results in witness lines that take away from the overall aesthetics of the refrigerator.
In certain refrigerators, gas assist handles are employed in an attempt to simplify the construction and assembly, while also improving the aesthetics. Such handle arrangements are also considered advantageous given their characteristic soft feel. Regardless, there still exists a need in the art for an improved refrigerator handle mounting arrangement preferably, but certainly not limited to, mounting a gas assist handle to a refrigerator in a manner which provides a tight, aesthetically appealing and easily assembled overall arrangement.
SUMMARY OF THE INVENTION
The present invention pertains to the mounting of a handle to a door face of a refrigerator. In accordance with the most preferred form of the invention, a base piece is initially attached to the face of the refrigerator, such as through the use of screws or the like. The base piece includes tapered surfaces, preferably at longitudinally spaced positions. Once the base piece is secured, a portion of a handle is placed over the base piece and slid relative to the base whereupon the tapered surfaces coact with structure of the handle such that an interference fit is developed to keep the handle tight to the door panel. With the handle in this position, one or more mechanical fasteners are driven into a body portion of the handle from a back side of the door panel. With this arrangement, all of the mechanical fasteners are hidden and witness lines, corresponding to those associated with conventional handle mounting arrangements, are avoided.
Additional objects, features and advantages of the present invention will be more readily apparent from the following detailed description of preferred embodiments of the invention, when taken in conjunction with the drawings wherein like reference numerals refer to corresponding parts in the several views.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With initial reference to
FIG. 1
, the handle arrangement of the invention is shown mounted to a refrigerator cabinet which is generally indicated at
2
. Although the handle arrangement can be applied to various different types and styles of refrigerators, as shown, refrigerator cabinet
2
includes a cabinet shell
5
formed from side panels
9
and
10
which are interconnected by a top panel
12
. Preferably, cabinet shell
5
is formed from bending a single piece of sheet metal in a manner known in the art. As illustrated, refrigerator cabinet
2
constitutes a side-by-side refrigerator having a fresh food compartment door
15
which is arranged laterally juxtaposed a freezer door
18
. Extending laterally across cabinet shell
5
, below fresh food and freezer doors
15
and
18
is a kickplate
20
. Aside from the aspects which will be described more fully below, the basic construction and operation of refrigerator cabinet
2
is known in the art, does not form part of the present invention and therefore will not be discussed further herein.
Fresh food door
15
includes an outer vertical edge portion
21
which is pivotally attached to cabinet shell
5
through upper hinge
23
and a lower hinge
24
. In accordance with the present invention, fresh food door
15
includes an upper inner edge portion
28
and an offset lower inner edge portion
30
. Therefore, upper and lower inner edge portions
28
and
30
are laterally spaced and extend in vertically offset planes or axes. In a generally similar manner, freezer door
18
includes an outer edge portion
38
which is pivoted at upper hinge
40
and lower hinge
42
for movement relative to cabinet shell
5
. In addition, freezer door
18
includes an upper inner edge portion
45
which is offset from a lower inner edge portion
47
. Again, the exact construction of refrigerator
2
can vary greatly without departing from the invention.
As opposed to a more conventional side-by-side refrigerator wherein inner edge portions of fresh food and freezer doors would be spaced by a vertical, single axis gap, fresh food and freezer doors
15
and
18
in accordance with refrigerator
2
are spaced in a central zone of refrigerator cabinet
2
by a gap
52
that includes a first vertical component between upper inner edge portions
28
and
45
, a lateral component between inner edge portions
28
and
47
and a second vertical component between lower inner edge portions
30
and
47
. Therefore, fresh food door
15
is wider in an upper portion thereof than in a lower portion. Correspondingly, freezer door
18
is wider in a lower portion than in an upper portion. As will become more fully evident below, fresh food and freezer doors
15
and
18
conceal fresh food and freezer compartments of refrigerator cabinet
2
which also have varying width upper and lower sections in accordance with the present invention. In any event, further details of this basic structure of refrigerator
2
is provided in U.S. Pat. No. 6,019,447 which is incorporated herein by reference.
The present invention is actually directed to the mounting of handles
60
and
61
for fresh food and freezer doors
15
and
18
respectively. Although the particular handle configuration can vary in accordance with the present invention, it is the particular mounting arrangement for one or more handles, such as handles
60
and
61
, to which the present invention is particularly directed. As shown, each handle
60
,
61
includes a first, elongated end portion
65
, a second end portion
66
, and an intermediate portion
67
interconnecting the first and second end portions
65
and
66
. At this point, it should be understood that the exact configuration of handles
60
and
61
merely represents a preferred arrangement and various handle designs could be readily employed without departing from the invention.
Reference will now be made to
FIGS. 2-5
in describing the preferred mounting of handle
61
in accordance with the present invention and it is to be understood that handle
60
is constructed and mounted in a corresponding manner. With initial reference to
FIG. 2
, a base plate
75
is initially mounted to lower inner edge portion
47
of freezer door
18
. In accordance with the most preferred embodiment of the invention, base plate
75
includes first, second and third spaced mounting sections
80
-
82
which are joined by elongated connecting sections
85
and
86
. First and second mounting sections
80
and
81
are substantially, identically constructed such that the preferred construction of second mounting section
81
will now be described in detail with particular reference to FIG.
3
and is to be understood that corresponding structure exists with respect to first mounting section
80
.
As shown in
FIG. 3
, second mounting section
81
includes a central recessed zone
90
within which is defined an elongated through slot
92
. Through slot
92
is adapted to receive a mechanical fastener
95
, such as a sheet metal screw, for use in attaching base plate
75
to freezer door
18
. Extending beyond the lateral dimensions of connecting sections
85
and
86
, second mounting section
81
is provided with side flanges
101
and
102
. Each side flange
101
,
102
includes a diverging portion
105
leading from connecting section
86
, as well as a sidewall portion
106
. As clearly shown in this figure in viewing sidewall
106
, each side flange
101
,
102
preferably tapers from adjacent a downwardly extending wall
110
towards diverging portion
105
. With this arrangement, each side flange
101
and
102
defines a tapering undercut for base plate
75
which is adapted to coact with a respective elongated tab portion
118
,
119
formed at a predetermined location along first end portion
65
of handle
61
. As clearly shown, each elongated tab portion
118
,
119
preferably defines a wedge surface
121
which is adapted to coact with a respective side flange
101
,
102
as will be detailed more fully below. At this point, it again should be realized that corresponding structure exists for both base plate
75
and second end portion
66
of handle
61
at first mounting section
80
.
FIG. 4
illustrates the preferred construction of third mounting section
82
and the interaction with first end portion
65
. Preferably, base plate
75
terminates in a raised projection
130
that is shown to be rounded. Projection
130
is generally flat and spaced from a recess
131
having a hole (not labeled) therein which is adapted to receive a mechanical fastener such as screw
133
in order to establish another connection location between base plate
75
and freezer door
18
. On the other hand, the terminal end of first end portion
65
of handle
61
is provided with an internal, arcuate ledge
135
which is adapted to slip under raised projection
130
upon mounting of handle
61
as will be detailed more fully below.
FIG. 5
illustrates a preferred construction of the rear portion of freezer door
18
, prior to attaching an inner door liner thereto. As shown, door
18
preferably includes a molded plastic cap
140
that has a rear, in-turn flange
144
formed with a pair of spaced, countersunk holes
146
and
147
. In general, holes
146
and
147
are adapted to receive mechanical fasteners such as screws (not shown) which extend through door
18
and are threadably received within second end portion
66
of handle
61
. More specifically, with the mounting arrangement of the present invention, base plate
75
is initially attached to lower edge portion
47
of freezer door
18
by mechanical fasteners as fully described above. In the most preferred embodiment of the invention, base plate
75
is molded of plastic. However, base plate
75
could be formed of metal. After base plate
75
is secured to lower inner edge portion
47
, handle
61
is arranged with first end portion
65
extending above base plate
75
such that ledge
135
is spaced from raised projection
130
and second edge portion
66
is spaced from holes
146
and
147
in the manner generally shown in FIG.
2
.
In this position, first end portion
65
of handle
61
can be completely laid over base plate
75
so as to extend about and substantially cover base plate
75
. Thereafter, the entire handle
61
is shifted or slid relative to base plate
75
, whereupon elongated tab portions
118
and
119
slip under side flanges
101
and
102
at each of first and second mounting sections
80
and
81
, while internal ledge
135
slips under raised projection
130
at third mounting section
82
. Due to the tapering of at least each sidewall
106
of side flanges
101
and
102
, as handle
61
is shifted in this manner, handle
61
is drawn against door
18
. That is, base plate
75
and handle member
61
include mating surfaces which coact along tapered portions thereof to draw handle
61
to the front side of door
18
upon shifting of handle
61
relative to base plate
75
. This interaction can occur simply due to tapering of each sidewall
106
at mounting sections
80
and
81
. In addition, a similar tapering could be employed at the interconnection between raised projection
130
and ledge
135
to perform a similar wedging function. In any event, handle
61
is shifted relative to door
18
and base plate
75
until a notch
160
formed in second end portion
66
abuts door cap
140
, with the shifting being further limited due to the presence of walls
100
, in order to properly align second end portion
66
with holes
146
and
147
to receive respective mechanical fasteners from the backside of door
18
. In the most preferred embodiment, base plate
75
actually tapers as clearly shown in referring to at least
FIGS. 3 and 4
. A similar configuration is preferably provided for elongated first end portion
65
of handle
61
. This overall tapering arrangement simply makes it easier to slide handle
61
, as discussed above, during the mounting process without causing any potential interference problems.
With this handle mounting arrangement, handle
61
can be advantageously formed of plastic, preferably with a cushioned intermediate section
67
preferably being created through a gas assist operation during molding for gripping purposes, and a tight, aesthetically appealing, as well as easily assembled, overall handle arrangement is defined. In any event, although described with reference to a preferred embodiment of the invention, it should be understood that various changes and/or modifications can be made without departing from the spirit of the invention. Therefore, in general, the invention is only intended to be limited in accordance with scope of the following claims.
