The present application claims priority to U.S. Provisional Patent Application No. 60/895,939, filed Mar. 20, 2007, entitled “Interlocking Panel,” the entire disclosure of which is hereby incorporated by reference in its entirety.
TECHNICAL FIELDEmbodiments of the invention pertain to interlocking panels and structures formed therefrom, and particularly to panels which may be assembled by engaging one another along their lengths for a removably coupled or interlocked engagement.
BACKGROUNDStructures having high flexural strength and rigidity as well as a degree of modifiability in terms of ultimate structure size are sometimes desirable. For example, tractor-trailer trucks may include cargo structures for transporting and/or storing material. Although the size of these structures may be known, it may be desirable to expand or decrease the size of the structure (for example, to accommodate the size of the trailer), or to completely disassemble the structure when not needed. In many cases, it is desirable for such an assembly process to be automated.
U.S. Publication No. 2006/059791 illustrates the use of panels having 1) a member-connecting side having a pivot-receiving slot for rotatably receiving the pivot, and 2) an arcuate wing-receiving slot for receiving the wing during relative rotation of at least one of the first and second members with respect to the other. This construction is inefficient and cumbersome, as it requires the rotating of the panels during assembly. Rotation of such panels makes the panels difficult to assembly quickly, particularly if the assembly process is to be automated.

Embodiments of the present invention may include panels configured to interlock to form various structures. In various embodiments, the interlocking panels may be suitable for applications including, for example, cargo enclosures for tractor-trailer trucks and similar vehicles. Other applications also may be within the scope of the present invention including storage structures, shipping containers and temporary shelters.
According to various embodiments, the panels may be interlocked by engaging the panels with each another along their lengths by a snap-fit/interlocked engagement. This novel structure allows for simple assembly by pushing one end of a panel into a complementarily configured other end of another panel without the need to rotate one or both of the panels, and generally without the need for special tools or complicated assembly techniques.
Panel 100 may be configured to couple to another panel. For coupling, receiving member 106 may be configured to engage a complementary engaging member (similar to engaging member 110) of another panel. Similarly, engaging member 110 may be configured to engage a complementary receiving member (similar to receiving member 106) of yet another panel. In various embodiments, one or both flanges 108 may be configured to flex to allow a complementary receiving member of another panel to engage engaging member 110.
Panel 200a may be coupled with panel 200b by inserting protruding end 202a of panel 200a into receiving end 204b of panel 200b. As illustrated in
As protruding end 202a is inserted into receiving end 204b, flanges 208b may flex to a degree sufficient to allow engaging members 210b to engage receiving members 206b. Once the engaging members 210b engage receiving members 206a, flanges 208b may snap back to their non-flexed position to hold panels 200a, 200b together, as illustrated in
According to various embodiments, the panels may be configured to provide a desired degree of flexural resistance. As illustrated in
Any material suitable for the particular application in which panels 200a, 200b are enlisted may be used to form panels 200a, 200b. For example, any one or more of various metals and their alloys may be appropriate or desirable for an application. Aluminum, for example, may be an appropriate material for a number of applications. In some embodiments, plastic or similar materials may be appropriate.
Panels in accordance with various embodiments of the present invention may be used for forming a variety of structures. For example, interlocked panels may be used for forming enclosures, doors, walls, or the like. In some embodiments, interlocked panels may be suitable for cargo enclosures configured to mount onto a vehicle such as, for example, tractor-trailer trucks, trains, or similar vehicles. Other applications also may be within the scope of the present invention including storage structures and temporary shelters.
As illustrated, structure 314 is formed from a plurality of interlocked panels 300, coupled as described herein. In various embodiments, panels 300 may be disposed, with respect to the resultant structure, in a generally horizontal, vertical, diagonal, or other orientation, depending on the application.
In some embodiments, one or more trim or edge structures 316 may be coupled to interlocked panels 300 for adapting structure 314 for the particular application. For example, trim structures 316 may include, for example, rail and/or stile elements (for a door, for example), hinges, or the like.
In some embodiments, panels may be further fastened in addition to interlocking. For example, in the embodiment illustrated in
Fasteners 424 may be used for fastening panels 400 together and/or for fastening one or more panels 400 to various trim structures 416. As described herein, trim structures 416 may be coupled to interlocked panels 400 for adapting structure 414 for the particular application, and may include, for example, rail and/or stile elements (for a door, for example), hinges, or the like.
Various fasteners 424 may be suitable for fastening panels 400 together. In various embodiments, suitable fasteners may include rivets. Other fasteners may be similarly suitable. For example, in some embodiments, any one or more of screws, bolts, clips, and/or pins may be used for fastening panels 400 together. In still further embodiments, panels 400 may be, welded, glued, or soldered together in addition to or instead of using mechanical fasteners.
An exemplary structure 514 formed using a plurality of panels is illustrated in
As illustrated in
Locking system 623 includes a locking bar 625 (illustrated in phantom), which may be disposed on a rear/inner surface or within the door, depending on the application. Accordingly, locking bar 625 may effectively be “invisible” from an exterior side of doors 618a, 618b. The placement of locking bar 625 on a surface other than an exterior surface of doors 618a, 618b may be desirable for providing a substantially smooth outer surface of doors 618a, 618b, security reasons (e.g., to prevent tampering with locking bar 625), and/or aesthetic reasons.
Locking system 623 may allow for locking and unlocking of doors 618a, 618b by way of a latch 626. In various embodiments, unlatching of latch 626 may cause locking bar 625 to rotate and either raise or lower (depending on whether latching or unlatching, respectively) for engaging or disengaging a receiver 627.
Structure 614 may include any number of locking systems 623, depending on the application. For example, in the illustrated embodiment, each of doors 618a and 618b include two locking systems 623. In various other embodiments, however, a door may include just one locking system 623 or may instead have none.
Other locking systems may be similarly suitable for locking doors or panels within the scope of the present disclosure. As illustrated in
