The present disclosure relates generally to a handle assembly for a residential or commercial appliance.
Known residential and commercial appliances, such as refrigerators, generally include a housing that defines one or more compartments for storage of items to be refrigerated and/or frozen. Exterior and interior doors and/or drawers can be provided for accessing these compartments. One or more handles are typically provided for manipulating these doors. Fasteners may be used to attach the handles or, in other constructions, the handles may be formed integrally.
For certain applications, shipping the appliance without one or more of the handles installed may be desirable. In the case of handles located on the exterior of the appliance, for example, shipping the appliance with the handle already installed can increase the footprint of the appliance. Additionally, installed handles can increase the amount of packaging materials required for protecting the appliance during shipping. For instance, a handle that protrudes from the surface may need special packaging to prevent damage during shipping.
Challenges exist, however, with providing one or more handles to be installed by the retailer or purchaser of the appliance. Commonly used handle constructions may require tools and/or skills that the retailer or purchaser may not possess. The installation process may require multiple steps and the presence of more than one person. Such factors may lead the retailer or purchaser to incorrectly install the handle or not even attempt installation, which in turn can lead to service calls and/or dissatisfaction with the product.
Also, where the handle assembly requires multiple parts, particularly small fasteners such as screws, bolts, and washers, such parts are typically shipped with the product. Unfortunately, this requires additional steps during manufacture and packaging. Additionally, such parts may be lost by the retailer or purchaser prior to, or during, installation.
Accordingly, a handle assembly for an appliance that can be shipped with the appliance uninstalled would be useful. A handle assembly with features that allow for installation without the use of tools and/or multiple small parts would also be useful. Such a handle assembly that can be used on a door, drawer, or component of a variety of different appliance types would be particularly beneficial.
The present invention provides a handle assembly that may be used on an appliance. The handle assembly can be installed without tools or the use of additional fasteners such as screws, bolts, and the like. The handle assembly can be installed onto doors, drawers or other components of a variety of different appliance types. Additional aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
In one exemplary embodiment, the present invention provides a handle assembly configured for mounting to a wall of an appliance. The wall defines normal, lateral, and transverse directions that are orthogonal to each other. The wall also defines a least one aperture. The handle assembly includes a receptacle positioned along an interior side of the wall of the appliance. The receptacle includes a receptacle cavity and at least one receptacle locking member. The receptacle locking member projects into the receptacle cavity along the lateral direction and defines a receptacle locking surface that extends along a transverse direction and a receptacle guiding surface that extends along the normal direction. A handle is positioned along an exterior side of the wall of the appliance. The handle includes a key that extends along the normal direction, through the aperture of the wall of the appliance, and into the receptacle cavity. The key defines a key locking surface that extends along the transverse direction and a key guiding surface that extends along the normal direction. The key locking surface is positioned substantially parallel to, and in contact with, the receptacle locking surface when the handle is installed.
In another exemplary embodiment, the present invention provides a slide-on handle assembly for an appliance, the appliance having a wall defining at least one aperture and defining a direction normal to the wall. The handle assembly includes a handle defining at least two keys spaced apart from each other along the lateral direction. Each key extends along the normal direction through the aperture in the wall and into the receptacle cavity. Each key defines at least one key locking member positioned at a distal end of the key and projecting along a lateral direction. The assembly also includes a receptacle defining a receptacle cavity and a pair of opposing side walls spaced apart from each other along the lateral direction. Each opposing side wall includes a plurality of receptacle locking members extending along the lateral direction into the receptacle cavity. The receptacle also defines guiding grooves and locking grooves with each of the guiding grooves and locking grooves positioned adjacent to at least one of the receptacle locking members. At least one of the key locking members is positioned in one of the locking grooves to fix the position of the handle on the wall of the appliance.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Concave portion 138 is positioned at a predetermined elevation convenient for a user to access ice or water enabling the user to access ice without the need to bend-over and without the need to access freezer compartment 124. In the exemplary embodiment, concave portion 138 is positioned at a level that approximates the chest level of a user.
In this exemplary embodiment, the insulated cavity is constructed and arranged to operate at a temperature that facilitates producing and storing ice. More particularly, the insulated cavity contains an ice maker for creating ice and feeding the same to a container 150 that is mounted on refrigerator door 126. As illustrated in
Operation of the refrigerator 100 can be regulated by a controller (not shown) that is operatively coupled to user interface panel 136 and/or paddle 134. Panel 136 provides selections for user manipulation of the operation of refrigerator 100 such as e.g., selections between whole or crushed ice, chilled water, and/or other options as well. In response to user manipulation of the user interface panel 136, the controller operates various components of the refrigerator 100. The controller may include a memory and one or more microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of refrigerator 100. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor.
The controller may be positioned in a variety of locations throughout refrigerator 100. In the illustrated embodiment, the controller may be located within the control panel area of door 126. In such an embodiment, input/output (“I/O”) signals may be routed between the controller and various operational components of refrigerator 100 such as a motor for rotating components of an ice crusher as will be described further below. In one embodiment, the user interface panel 136 may represent a general purpose I/O (“GPIO”) device or functional block. In one embodiment, the user interface 136 may include input components, such as one or more of a variety of electrical, mechanical or electro-mechanical input devices including rotary dials, push buttons, and touch pads. The user interface 136 may include a display component, such as a digital or analog display device designed to provide operational feedback to a user. The user interface 136 may be in communication with the controller via one or more signal lines or shared communication busses.
The exemplary door handle assembly of the present invention includes a handle that mates with a receptacle in a complementary manner and with a wall or surface of an appliance positioned at least partially therebetween. The wall may form part of a door, drawer, or other compartment in the appliance. The handle is inserted into the receptacle and slides into a fixed position to secure the handle onto the appliance. By way of example,
Each distal end 206 of handle 200 includes a base 204 from which at least one key 210 extends along a normal direction N as shown more particularly in
Key 210 defines key locking members 212 and 214, which are each positioned at distal end 244 (
Referring now to
In a manner that will be further described, keys 210 and 220 are received into a receptacle 250, which is illustrated in
For this exemplary embodiment of the handle assembly, opposing side wall 290 includes a plurality of receptacle locking members 260 and 262 that extend along lateral direction L into the receptacle cavity 252. Similarly, opposing side wall 292 includes a plurality of receptacle locking members 264 and 266 that also extend along lateral direction L into the receptacle cavity 252 and towards opposing side wall 290. Although two receptacle locking members are shown on each of the opposing side walls 290 and 292, in other embodiments of the invention one, two, or more receptacle locking members may be used on either or both of the opposing side walls 290, 292. The number of receptacle locking members and associated features may be selected depending upon, for example, the number of key locking members on each key of handle 200.
Referring now to the cross-sectional view of receptacle 250 shown in
Continuing with
During installation, handle 200 is manipulated so that keys 210 and 220 are inserted through one or more openings or apertures 208 defined by wall 203. Apertures 208 are located along wall 203 or other surface of the appliance depending where handle 200 is to be located. Keys 210 and 220 are inserted through aperture 208 along normal direction N so that e.g., key locking members 212 and 214 are received into guiding grooves 278 and 284. Key locking members 212 and 214 slide along grooves 278 and 284, as indicated by arrows S, while receptacle guiding surface 272 (
Once keys 210 and 220 are fully inserted into receptacle 250, handle 200 is then manipulated so that keys 210 and 220 are moved along transverse direction T as indicated by arrows D. This movement causes key locking members 212 and 214 to move along locking grooves 280 and 282 (
A variety of different features may be used to secure handle 200 once installed into the position shown in
The locking of handle 200 into place secures handle 200 onto the wall 203 of appliance 200 by trapping wall 203 between handle 200 and one or more receptacles 250 positioned at distal ends 206. Each receptacle 250 may be held in place against the interior surface 205 of wall 203 by insulation, fasteners, and or other features. Accordingly, during e.g., manufacture and shipping, receptacle 250 is held into position adjacent aperture 208 so that handle 200 may be installed by a retailer or purchaser without the use of special tools. Because handle 200 can be installed after shipping, the footprint and/or packaging materials required for shipping appliance 100 can be reduced.
As mentioned, other features may be used to fix the position of handle 200. By way of example, teeth could be placed on one or more of the receptacle locking surfaces to engage with teeth on one or more of the key locking surfaces. Alternatively, or in addition thereto, interference fits and other features could also be used.
As described above, after insertion (arrows S in
In a complementary manner, receptacle locking members 260 and 262 include receptacle locking surfaces 268 and 270 having portions 267 and 269 that are also at angle α. Accordingly, handle 200 is positioned into receptacle 250 along guiding grooves 278 and 284 and is then fixed into position in locking grooves 280 and 282 with key locking members 212 and 214 engaging receptacle locking members 262 and 260, respectively.
