Description

BACKGROUND OF THE INVENTION

[0002] The present invention relates to a storage unit. The present invention also relates to a storage unit having a box formed from a one-piece integral sheet.

[0003] It is known to provide a storage unit, such as a locker, for use in a workplace, or other institutional, public, government, educational, commercial, or municipal facility such as schools, health clubs, athletic facilities, parks, aquatic centers, military facilities, food processing plants, police departments, recreation centers, theme parks, transportation facilities (e.g., airports, bus stops, train stations, etc.), and the like. Known storage units typically include a door mounted to an enclosure or “box” comprised of side walls, a rear wall, a top, and a bottom metal, and other materials. The box for such known storage units typically is assembled from separate pieces using adhesive, mechanical fasteners, or dovetail joints.

[0004] However, such storage units may present disadvantages, such as a large number of parts to assemble, restrictive tolerances or undue precision required for assembly and installation, cost and time burden of assembly, overall configurations that tend to show visual defects or imperfections, the costs of skilled labor, inspection and occasional repair or quality control during and after assembly or installation, and other problems that tend to be associated with assembling and installing such known storage units. For example, aligning and joining adjacent walls (e.g., each at right angles) typically require precision drilling and alignment, multiple fixturing positions, and labor to apply the adhesive or fasteners. Even then, there may be pieces damaged (e.g., split) by the fasteners, adhesive applied to undesired locations, visual defects caused by the fixturing, and the like.

[0005] Accordingly, it would be advantageous to provide a less costly storage unit that is of a configuration that is relatively easy to assemble and install. It would also be advantageous to provide a storage unit that is constructed of fewer components and/or fabricated from fewer parts (e.g., integrally molded or machined). It would further be advantageous to provide a storage unit with or providing any one or more of these or other advantageous features.

SUMMARY OF THE INVENTION

[0006] The present invention relates to a locker comprising an enclosure having a first panel and a second panel connected to the first panel by a hinge member. The first and second panels and the hinge member are unitarily formed and a door with a latch mechanism releasably coupled to one of the first and second panels.

[0007] The present invention also relates to a unitarily formed enclosure for a locker comprising a first wall, a second wall, and a web. The web connects the first wall and the second wall, and has a thickness less than the thickness of the first and second walls. The first wall, second wall, and web are configured to provide a continuous outer and/or inner surfaces without seams at the interface therebetween.

[0008] The present invention further relates to a method of assembling a storage unit. The method comprises providing a unitary sheet having a first portion with a first surface and a second portion with a second surface, the first portion being connected to the second portion by a hinge member. The method further comprises joining the first surface to the second surface by applying heat to one of the first surface and the second surface, melting at least a portion of the material at the first or second surface to which heat is applied, and pivoting the first portion relative to the second portion about the hinge until the first surface contacts the second surface.

[0009] The present invention further relates to a method of assembling a storage unit comprising providing a sheet of plastic material, and a pair of grooves to the sheet. The grooves may be formed by heat, by milling, during fabrication of the sheet, combinations thereof, or the like. The pair of grooves is configured to separate the sheet into a first portion, a second portion, and a third portion. The method further comprises applying a heating member to one or more surfaces that define the grooves thereby melting some of the plastic material thereon. The method further comprises pivoting the first and third portions so that the surfaces of the grooves contact and join as the melted plastic material solidify.

[0010] The present invention further relates to a storage unit comprising an enclosure portion, and a cap including a facing portion and a mounting portion coupled to the panel by a web. The facing portion, mounting portion, and web are unitarily formed.

According to exemplary embodiments, box 14 may have any of a variety of configurations, shapes, sizes, number of walls, etc. (e.g., the box may be made of one or more walls that may provide a rectangular space or a non-rectangular space (e.g., circular, arcuate, ovular, elliptical, cylindrical, etc.). Space 30 may be configured to include one or more shelves 29, hooks, and other accessories or options intended to provide for a variety of storage arrangements. A panel (shown as a divider 31 in FIGS. 1 and 16) may be included to provide multiple lockers 12 for a single box 14.

[0028] According to a preferred embodiment shown in FIGS. 2-5, side walls 22, rear wall 26, and flange 27 of box 14 are integrally (or unitarily) formed from a single piece (e.g., a sheet 38 of material) with the walls being connected by a web 32 (e.g., strip of material or “hinge” or the like). The enclosure is formed by pivoting or folding side walls 22 about web 32 and fixing walls 22, 26 in place. Side walls 22 and rear wall 26 may be fixed or welded in place by melting surfaces 35 of the groove 34 prior to pivoting side walls 22 in place. According to an alternative embodiment shown in FIGS. 14 and 15, the top wall and/or bottom wall are integrally formed with the side walls and rear wall from a single piece and connected by the web. According to an alternative embodiment, the side walls, rear wall, and flange of the box may be fabricated using any of a variety of techniques (e.g., extrusion, casting, various molding processes, deep drawing, etc.).

[0029] Referring to FIG. 5, web 32 is configured to provide a “living hinge” so that side walls 22 and rear wall 26 may be positioned during assembly to provide box 14 and define space 30 (e.g., rotated, pivoted, folded, etc.).

[0030] Web 32 may be formed by any of a variety of manufacturing techniques. According to a preferred embodiment, a groove 34 (e.g., a relief notch, slot, etc.) is provided to a sheet 38 (e.g., stock plastic material) to form web 32 to connect the walls and the flange. According to a particularly preferred embodiment, groove 34 is formed by removing material from sheet 38 (e.g., with one or more machining operations). According to an alternative embodiment, the groove may be formed during fabrication of the sheet (e.g., is integrally molded during casting, extrusion injection molding, extruded, etc.) such that the side walls and rear wall are formed or molded as a single piece connected by the web. According to an alternative embodiment, the groove is formed as the heating bar or member contacts the sheet and melts the plastic material. As heating member 36 is contacting surfaces 35 of groove 34, a block 48 may be used to support sheet 38.

[0031] Groove 34 may have any of a variety of configurations that allow side walls 22 and rear wall 26 to be moved to the desired position.
