Throughout the drawings and the detailed description, unless otherwise described, the same drawing reference numerals will be understood to refer to the same elements, features, and structures. The relative size and depiction of these elements may be exaggerated for clarity, illustration, and convenience.
Examples incorporating one or more embodiments are described and illustrated in the drawings. These illustrated examples are not intended to be limiting. For example, one or more aspects of an embodiment may be utilized in other embodiments and even other types of devices.
For purposes of the description herein, the setting of softened thermoplastic material may be representative of any number of occurrences, including, but not limited to, forming, cooling, surrounding, fitting, embedding, heating, and solidifying.
An example cabinet 100 is illustrated in
Example doors 125, 130, 131 illustrated in
In examples illustrated herein, the plastic sheet 200 is positioned as a rear wall of the compartment 150 that separates the compartment 150 from the rear wall 105 of the cabinet 100. However, embodiments described herein are not limited thereto. For example, the plastic sheet may be formed in such a way as to define any portion of the compartment 150, including, but not limited to the side walls 165 and the top wall 160 of the compartment 150.
As is illustrated in
The example cabinet 100 can be provided with more than one compartment 150 as well as any other type of compartment. The plastic sheet 200 described herein may be used to respectively define or partially define any type of compartment, including, but not limited to, compartments implemented in and with respect to refrigerators and various household appliances, furniture, drawers, automobiles, closets, organization, and architecture.
With respect to the form of the example plastic sheet 200 that is applied to partially define the compartment 150 of the cabinet 100, thermoplastic material may be softened by heating or other methods and set partially around an example component 300, which is illustrated in
As is illustrated in
For example, to create the plastic sheet 200 including the formed portion 205 that is set partially around the component 300, thermoplastic material may be softened by heating or other methods in such a way as to surround a rear profile 310 of the component 300 defined by one or more flanges 310, as is illustrated in
However, contrary to the function of a die, the softened thermoplastic material of the example described herein may be permitted to set around the surfaces of the rear profile 310 of the component 300, thereby serving to embed the component 300 in the same formed portion 205 that the component 300 was utilized to create in such a way that the formed portion 205 is fitted to the rear profile 310 of the component 300. Thus, the complexity of thermoforming operations could be reduced in that the component 300 may be able to define its exact mounting envelope within the plastic sheet 200, as more complex envelope geometry may increase dimensional accuracy in placement of the component 300 during thermoforming.
In addition, the embedding of the component 300 within the formed portion 205 of the plastic sheet 200 may be permanent, as the component 300 might not be removable from the structure of the formed portion 205 after the setting of the softened thermoplastic material. Moreover, the component 300 may be supported by the plastic sheet 200 without the use of fasteners, anchor nuts, punctures or holes within the plastic sheet 200, or piercings of the plastic sheet 200 after the foam insulation 500 is provided between the plastic sheet 200 and the outer wall 105. Further, the component 300 may be supported either solely by the strength of the plastic sheet 200 or by a combination of the strength of the plastic sheet 200 and the force provided by the foam insulation 500. This may result in a reduction of parts needed to construct the cabinet 100, as well as a subsequent reduction of the tooling costs associated with the reduction of parts.
The setting of the thermoplastic material around the flanges 310 of the component 300 may cause the formed portion 205 to contact at least one of the flanges 310 on two or more sides, thereby embedding the aforementioned flange 310 in the formed portion 205. Further, a notched area of the formed portion 205 may set between flanges 310, further serving to embed the flanges 310. Moreover, while not limited hereto, a servo-controlled robot may be utilized to position the component 300 in a location at which the plastic sheet 200 including the formed portion 205 can be created.
In addition, while the rear profile 310 of the component 300 is illustrated as flanges, embodiments described herein are not limited thereto. For example, any sort of flange, projection, lip, overhang, outcropping, protuberance, or extension may be used alone and/or in combination to form a rear profile by which a component can form and be embedded within a formed portion of a plastic sheet.
Further, while a single component 300 is applied to a single formed portion 205 of the plastic sheet 200 in the examples illustrated and described herein, embodiments described herein are not limited thereto. For example, a plurality of the components 300 may be embedded within a respective plurality of the formed portions 205 within the plastic sheet 200.
The example component 300 is more particularly illustrated in
The example component 300 illustrated herein may resemble and possess functionality of an example rail statically positioned at a rear wall of the compartment 150, when, in this case, the rear wall of the compartment 150 is represented by the plastic sheet 200. The example rail 300 may be one of a plurality of rails 300 around which a plurality of formed portions 205 is respectively set with the rails 300 being respectively embedded within the formed portions 205.
The rails 300 may include one or more receptacles 305 to which the article 400 is configured to be removably anchored and supported by the plastic sheet 200. The receptacles 305 are open to the compartment 150 and, as such, may be provided at a portion of the component or rail 300 around which the formed portion 205 is not positioned, thereby allowing the receptacles 305 to be accessed for various functional purposes. For example, the article 400 illustrated in
While the example component 300 illustrated herein may resemble and possess functionality of a rail positioned at the plastic sheet 200 of the cabinet 100, embodiments described herein are not limited thereto. For example, a component may serve to transport various articles within a cabinet from one location to another. In addition, a component may be a fixture to enable the installation of an additional component within the cabinet. Further, while an example of the article 400 described and illustrated herein resembles and possesses the functionality of a cantilever shelf, embodiments described herein are not limited thereto. For example, an article may be any item known to one having ordinary skill in the art to benefit from being hung within a cabinet, such as, but not limited to, a bin, a tray, a drawer, and rails to slidably support baskets and drawers.
As is illustrated in
The shelf assembly 400 may be one of a plurality of shelf assemblies 400 configured to removably anchor corresponding shelf surfaces 405 to at least two of the rails 300. The shelf anchors 410 may be positioned at opposite sides of a shelf assembly 400 and configured to removably anchor one of the shelf assemblies 400 to at least two of the rails 300 when inserted into the receptacles 305 respectively positioned in the two rails 300.
A number of examples have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described elements are combined in a different manner and/or replaced or supplemented by other elements or their equivalents. Accordingly, other implementations are within the scope of the following claims.
