The disclosure generally relates to a shelf and, more particularly, to a shelf with wooden board supports.
Shelving systems, such as modular shelving systems, are known for storing and supporting items of all types. Typically, shelving systems contain several components that can be easily assembled to conform to a customer's needs. The shelving systems can include shelves, support posts, and connectors, for example.
It is desirable for each shelf to be formed from a lightweight material such as plastic to facilitate portability and ease of assembly of the shelving system. Many plastic shelving systems are shown in the prior art, including plastic shelving systems that fit together and assemble. For example, U.S. Pat. No. 4,706,576 to Barry James shows a rectangular shelving system capable of assembly into multiple configurations. Although plastic shelving systems are often lighter and more convenient to assemble than conventional shelving, plastic shelving systems often lack the same rigidity and strength as conventional shelving.
There is a continuing need for a shelf or shelving system that is lightweight. Desirably, the shelf also minimizes manufacturing costs and complexity of assembly while maximizing a strength and stiffness thereof.
In concordance with the instant disclosure, a shelf that is lightweight, minimizes manufacturing costs and complexity of assembly, and maximizes the strength and stiffness thereof, has surprisingly been discovered.
In one embodiment, a shelf includes a main body and a plurality of support features. The support features are formed in the main body. Each of the support features include a board having an overmolded exterior. The shelf capable of standing on its own, or connected to a shelving structure.
In a further embodiment, a shelf includes a main body and a plurality of support features. The support features are formed in the main body. Each of the support features includes a board, wherein the board contains a plurality of apertures. The board has an overmolded exterior extending through the apertures. The shelf capable of standing on its own, or connected to a shelving structure.
In another embodiment, a shelf includes a main body and a plurality of support features disposed on the main body. Each of the support features includes a recess formed in the main body. A removable board is received within the recess. An insert is coupled to the main body and maintains the board within the recess. The shelf capable of standing on its own, or connected to a shelving structure.
The above, as well as other advantages of the present disclosure, will become readily apparent to those skilled in the art from the following detailed description, particularly when considered in the light of the drawings described hereafter.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should also be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features. In respect of the methods disclosed, the order of the steps presented is exemplary in nature, and thus, is not necessary or critical.
The shelf 10 includes a main body 12 having walls 14. The walls 14 are integrally formed with the main body 12 and extend therefrom. In the embodiments shown, the main body 12 is substantially rectangular and has four corners. Other shapes for the shelf 10 may also be selected by a skilled artisan within the scope of the present disclosure.
The main body 12 includes corner openings 16. The corner openings 16 are formed therein for receiving posts or supports, and for facilitating stacking of the shelf 10. While four openings 16 are illustrated, more than four or less than four corner openings 16 can be contemplated for use, depending on the overall shape of the main body 12 selected.
The main body 12 is formed from a lightweight plastic material such as a polypropylene plastic material, by a molding process such as injection molding, as nonlimiting examples. It should be understood, the shelf 10 can be formed from any suitable material, including other thermoplastic materials such as polyethylene, for example, and non-thermoplastic materials such as foam or metal, for example. Any suitable processes for forming the shelf 10 may also be employed, as desired.
With further reference to
In the embodiment illustrated in
The board 22 may have an overmolded exterior 24. The overmolded exterior 24 is a plastic exterior that is molded over the board 22 by an overmolding process. The overmolded exterior 24 can be formed by other materials, as desired. The overmolded exterior 24 of each of the support features 20 may be integrally formed with the main body 12 in an overmolding operation. For example, the board 22 can be positioned in a mold for forming the main body 12. The molding material, such as a thermoplastic, is then used with the mold to form both the main body 12 and the overmolded exterior 24, over the board 22. The shelf 10 is thereby provided as an integral unit.
In another embodiment, the overmolded support features 20 can be formed separately from the main body 12, through a separate injection molding process, and subsequently coupled thereto with mechanical or adhesive fasteners.
As illustrated in
As shown in
To assemble and form the shelf 10, the boards 20 are positioned in the mold for forming the main body 12. The apertures 26 can be pre-formed into the board 22 prior to positioning the boards 22 in the mold. A molding material, such as thermoplastic, is then disposed or injected into the mold. The overmolded exterior 24 is formed by the molding material flowing over the boards 22, and in certain embodiments through the apertures 26 of the boards 22, during the overmolding process.
Advantageously, the support features 20 including the board 22 maximize an overall strength, stiffness, and rigidity of the shelf 10, while maintaining a lightweight shelf 10.
It should be appreciated that the apertures 26 formed in the board 22 can also be employed to guide locating pins of the mold therein. The apertures 26 used to guide the locating pins of the mold facilitate proper positioning of the boards 22 within the mold. The overmolded exterior 24 extending through the apertures 26 further maximizes an overall strength, stiffness, and rigidity of the shelf 10.
In these further embodiments, the support features 20 of the shelf 10 include elongate recesses 28 that are formed in the main body 12. The shape of each of the recesses 28 corresponds in shape to one of the boards 22. In operation, the recesses 28 receive the boards 22.
As illustrated in
With renewed reference to
In particular examples, an outer surface of the insert is substantially flush with the outer surface of the remainder of the main body 12, to thereby create a uniform outer surface of the resulting shelf 10. In these examples, a depth of each of the elongate recesses 28 may be greater than a height of each of the boards 22 disposed within the recesses 28 by a dimension equivalent to a thickness of the insert 30. It should be understood that such dimensions advantageously result in an abutting of the boards 22 to both the bottom of the recesses 28 and the underside of the inserts 30, without the forming of any gaps therebetween.
In certain embodiments, shown in
In other embodiments, the insert 30 can be coupled to the main body 12 by other suitable means such as a welding, friction welding, press fitting the inserts 30 with the main body 12, or by employing mechanical coupling devices such as screws, nails, pins, and the like. The use of chemical adhesives to couple the insert 30 to the main body 12, and thereby secure the support 20 within the recess 28, is also contemplated and within the scope of the present disclosure.
As shown in
To assemble and form the shelf 10 illustrated in
Advantageously, the boards 22 add a strength, rigidity, and stiffness to the shelf 10. It is understood that the boards 22 can also be removed from the shelf 10 to minimize an overall weight of the shelf 10, for example, during storage and shipping of the shelf 10, as desired.
While certain representative embodiments and details have been shown for purposes of illustrating the invention, it will be apparent to those skilled in the art that various changes may be made without departing from the scope of the disclosure, which is further described in the following appended claims.
This application claims the benefit of U.S. Provisional Application No. 62/320,749, filed on Apr. 11, 2016. The entire disclosure of the above application is hereby incorporated herein by reference.
