BACKGROUND
Modular shelving units may be utilized to store various objects, such as paint cans, athletic equipment and the like. However, conventional shelving units may be difficult to assemble and in some situations, it may be desirable to selectively limit access to objects positioned on the shelving units. Furthermore, conventional modular shelving units may have limited assembly configurations that may not be suitable for the storage of some objects, such as soccer balls, basketballs, or the like.
Accordingly, a need exists for modular storage assemblies that are configured for easy assembly and that permit multiple assembly configurations suitable for the storage of a variety of objects.

I. EXEMPLARY MODULAR STORAGE ASSEMBLY
Modular storage assemblies configured to store and organize items are described herein. In embodiments, the storage assemblies may include a plurality of shelves that are selectively coupled to post assemblies by a toothed retaining ring. The toothed retaining ring may assist preventing the assembly of the shelf to the post assembly until a user has positioned the retaining ring at a desired height on the post assembly. The storage assemblies may further include one or more door panels that may form a door assembly to selectively prevent access to an interior of the storage assembly.
Referring initially to FIG. 1, a modular storage assembly 100 is schematically depicted. The modular storage assembly 100 is assembled to form a storage rack 102 including post assemblies 110 and one or more shelves 120 selectively coupled to the post assemblies 110. In the embodiment depicted in FIG. 1, the modular storage assembly 100 includes four post assemblies 110 positioned at four opposing corners of the storage rack 102. When assembled, the post assemblies 110 generally extend upward in the vertical direction, and the one or more shelves extend in the longitudinal and lateral directions between the opposing post assemblies 110. The shelves 120 may be selectively coupled to and removable from the post assemblies 110. The position of the shelves 120 with respect to the post assemblies 110 may also be adjustable in the vertical direction, as will be described in greater detail herein.
Referring to FIG. 2, an exploded view of the storage rack 102 is schematically depicted. Each of the post assemblies 110 include one or more post members 112 that are selectively coupled to and removable from one another. The post members 112 may be substantially similar and interchangeable with one another, as will be described in greater detail herein. Retaining rings 140 are positioned between the one or more post members 112 and the one or more shelves 120 to selectively couple the shelves 120 to the post members 112. The storage rack 102 may optionally include one or more end caps 190 that are selectively coupled to the top of the post assemblies 110 and supporting feet 192 that are selectively coupled to the bottom of the post assemblies 110. In embodiments, each of the shelves 120, post members 112, and the retaining rings 140 are formed of a resin material, and may be formed through a molding process. In other embodiments, the shelves 120, the post members 112, and the retaining rings 140 may be formed of any suitable material, such as a polymer, a composite, or the like, and may be formed through any suitable manufacturing process. In some embodiments, the shelves 120, the post members 112, and the retaining rings 140 are all formed from the same material. In other embodiments, the shelves 120, the post members 112, and the retaining rings 140 may be formed from different materials and/or different combinations of materials.
Referring to FIGS. 3A and 3B, a pair of post members 112 are depicted in isolation. The post members 112 may have a generally cylindrical shape and may define a hollow tube. In other embodiments, the post members 112 may define any suitable shape, including, but not limited to square-shaped tube, a rectangular-shaped tube, an ovular-shaped tube, or the like, and the post members 112. Additionally, while the post members 112 are described herein as defining hollow tubes, it should be understood that the post members 112 may include a solid construction. The post members 112 include a female end 116 and a male end 118 positioned opposite the female end 116. The male end 118 defines an outer diameter that is less than an inner diameter of the female end 116. In embodiments, when post members 112 are assembled to one another, the male end 118 of one post member 112 may be at least partially inserted within the female end 166 of another post member 112. In this way, multiple post members 112 may be assembled to one another to form the post assembly 110 (FIG. 2).
Each of the post members 112 include a plurality of annular grooves 114 that extend around a perimeter of the post members 112. The annular grooves 114 extend inward into an outer perimeter of the post members 112 in a radial direction, forming a cavity within the post members 112. In other embodiments, the annular grooves 114 may extend outward from the outer perimeter of the post members 112, or may define shapes having both inwardly and outwardly extending portions. Each of the post members 112 multiple annular grooves 114 that are spaced apart from one another along a length of the post members 112. Each of the annular grooves 114 of the post members 112 are configured to engage a retaining ring 140 (FIG. 2) to selectively couple a shelf 120 (FIG. 2) to the post member 112, as will be described in greater detail herein. The annular grooves 114 may be regularly spaced and equidistant from one another along the length of the post members 112. In other embodiments, the annular grooves 114 may be irregularly spaced apart from one another along the length of the post members 112.
Referring to FIGS. 4A and 4B a front and a rear perspective view of a shelf 120 of the storage assembly 100 are schematically depicted, respectively. The shelves 120 define apertures 122 positioned at four opposite corners of the shelf 120. In the embodiment depicted in FIGS. 4A and 4B, the shelves 120 generally define a rectangular shape, however, it should be understood that the shelves 120 may define any suitable shape, for example and without limitation, a square shape, circular shape, an elliptical shape, or the like. The apertures 122 extend through the shelves 120 and are configured to engage the retaining rings 140 (FIG. 2) as will be described in greater detail herein. Each of the apertures 122 define a toothed profile 124 oriented to face radially inward into each of the apertures 122. The toothed profiles 124 are configured to engage the retaining rings 140 (FIG. 2) to restrain the shelves 120 with respect to the post assemblies 110.
Referring to FIGS. 5A and 5B, an enlarged view of one of the apertures 122 and a section view of one of the apertures 122 are schematically depicted, respectively. The toothed profile 124 extends around the aperture 122 and is oriented to face radially inward. The toothed profile 124 defines a plurality of teeth 125 that extend outward from an inner perimeter 123 of the aperture 122 to form the toothed profile 124. While the plurality of teeth 125 depicted in FIGS. 5A and 5B extend along the aperture 122 in the vertical direction (i.e., a spur gear configuration), it should be understood that the plurality of teeth 125 may include any suitable configuration, such as a helical gear configuration or the like.
Referring to FIG. 6A, a bottom view of the shelf 120 is schematically depicted. The shelf 120 includes a grating 128 including a plurality of grate members 129 that define a plurality of openings through the shelf 120. In some embodiments, individual grate members 129 may extend to the outer perimeter of the shelf 120, which may assist in providing structural rigidity to the shelf 120.
Referring to FIG. 6B, a section view of one of the apertures 122 along section 6B-6B of FIG. 6A is schematically depicted. The aperture 122 includes a narrow end 130 that is positioned opposite a wide end 132, where the wide end 132 has an inner diameter that is greater than the narrow end 130. The aperture 122 includes a generally tapered shape in which the inner diameter of the aperture 122 increases moving along the aperture 122 from the narrow end 130 to the wide end 132. By having a tapered shape, the apertures 122 may engage the retaining rings 140 (FIG. 2), thereby restricting movement of the shelf 120 in the vertical direction when installed to the post assembly 110, as will be described in greater detail herein.
Referring to FIG. 7, a side view of the shelf 120 is schematically depicted. Each of the shelves 120 may include one or more trusses 127 extending around the perimeter of the shelf 120 and extending between a top and a bottom of the shelf 120. The trusses 127 may assist in providing structural rigidity to the shelf 120. The shelf 120 further includes a male coupling member 136, a female coupling member 134, and a wall mount 133 positioned around the perimeter of the shelf 120. In embodiments, the male coupling member 136 is positioned on a side of the shelf opposite the female coupling member 134, and the wall mount 133 is positioned on a side of the shelf adjacent to the male coupling member 136 and the female coupling member 134. The wall mount 133 is configured to fasten the shelf 120, and accordingly, the assembled storage assembly 100 (FIG. 1) to a wall. In embodiments, the wall mount 133 may be configured to receive a mechanical fastener, such as a nail, a screw, or the like, which may fasten the shelf 120, and accordingly, the assembled storage assembly 100 (FIG. 1) to a wall.
Referring to FIG. 8A an enlarged perspective view of the female coupling member 134 is schematically depicted. The female coupling member 134 may extend at least partially outward from the shelf 120 and defines an aperture 135 configured to receive the male coupling member 136.
Referring to FIG. 8B, an enlarged perspective view of the male coupling member 136 is schematically depicted. The male coupling member may extend at least partially outward from the shelf 120 and includes a downwardly extending tab 137 that is configured to be at least partially inserted into the aperture 135 of the female coupling member 134. The female coupling member 134 and the male coupling member 136 to couple adjacent shelves 120, and accordingly adjacent modular storage assemblies 100 (FIG. 1) to one another. While both the male coupling member 136 and the female coupling member 134 are described herein as extending at least partially outward from the shelf 120, in some embodiments one of the male coupling member 136 and the female coupling member 134 may extend outward from the shelf 120 while the other of the male coupling member 136 and the female coupling member 134 is recessed within the shelf 120.
Referring to FIGS. 9A and 9B, a front and a rear view of another shelf 120 are schematically depicted, respectively. The shelves 120 define the apertures 122 and the toothed profiles 124, however, in the embodiment depicted in FIG. 5, the shelves 120 define a planar surface 126, as compared to the grating 128 (FIG. 4). By having a planar surface 126, the shelf 120 may accommodate storage of items that may not be suitable for storage on a shelf including a grating.
Referring to FIGS. 10A and 10B, a top and a bottom view of a retaining ring 140 are schematically depicted, respectively. The retaining rings 140 have a generally annular shape that is complementary (i.e., corresponding to and the opposite of) with the post assembly 110. The retaining rings 140 have a toothed profile 142 positioned on an outer perimeter of the retaining rings 140, and the toothed profile 142 may be complementary with the toothed profile 124 of the shelves 120 (FIG. 4). The toothed profile 142 of the retaining ring 140 includes a plurality of teeth 143 that extend outward from the outer perimeter of the retaining ring 140, where the plurality of teeth 143 is configured to engage the teeth 125 (FIG. 5B) of the aperture 122. In particular, individual teeth of the plurality of teeth 143 of the retaining ring are shaped to fit between the teeth 125 (FIG. 5B) of the aperture 122 when the retaining ring 140 is inserted within the aperture 122. In other embodiments, the plurality of teeth 143 may include the same number of individual teeth as the teeth 125 (FIG. 5B) of the aperture 122. In other embodiments, the plurality of teeth 143 may be less than the number of teeth 125 of the aperture 122. In other embodiments, the plurality of teeth 143 may be more than the number of teeth 125 of the aperture 122
Each of the retaining rings 140 have a narrow end 150 positioned opposite a wide end 152, where the retaining ring 140 has a greater outer diameter at the wide end 152 as compared to the narrow end 150. As the retaining ring 140 has a greater outer diameter at the wide end 152, the retaining ring has a generally tapered shape, with the outer diameter of the retaining ring 140 increasing moving along the retaining ring 140 from the narrow end 150 to the wide end 152. The tapered shape of the retaining ring 140 may assist in engaging the retaining ring 140 with the apertures 122 of the shelves 120.
The retaining rings 140 include one or more annular ridges 144 extending inward from an inner perimeter of the retaining rings 140. The annular ridges 144 are spaced apart from one another and are configured to engage the annular grooves 114 of the post assembly 110 when the retaining rings are installed to the post assembly 110.
The retaining rings 140 include a gap 148 extending along a length of the retaining rings 140. The gap 148 may allow the retaining rings 140 to elastically deform in a radial direction such that the retaining rings 140 may be installed to the post assemblies 110.
Referring to FIGS. 11A-11C, a shelf 120 is depicted being installed to a post assembly 110. Initially, the retaining ring 140 is installed to the post assembly 110 by positioning the retaining ring 140 over the post assembly, as shown in FIGS. 11A and 11B. The retaining ring 140 may be installed such that the wide end 152 is positioned below the narrow end 150 of the retaining ring 140. In some embodiments, the inner diameter of the retaining ring 140 may be less than an outer diameter of the post assembly 110, such that the retaining ring 140 may have an interference fit with the post assembly 110. Additionally, the annular ridges 144 of the retaining ring 140 may engage the annular grooves 114 of the post assembly 110 to retain the position of the retaining ring 140 on the post assembly 110 in the vertical direction. As described above, the retaining ring 140 may be elastically deformable in a radial direction, and the retaining ring 140 may be disengaged from the annular grooves 114 of the post assembly 110 by expanding the retaining ring 140 in the radial direction. In this way, the retaining ring 140 may be repositionable along the post assembly 110.
Once the retaining ring 140 is positioned on the post assembly 110, the aperture 122 of the shelf 120 is positioned over the post assembly 110 and the retaining ring 140, as shown in FIGS. 11B and 11C. The aperture 122 of the shelf 120 may be oriented such that the narrow end 130 of the aperture 122 is positioned above the wide end 132 of the aperture 122. The aperture 122 of the shelf 120 may be engaged with the retaining ring 140, and in particular, the toothed profile 124 of the aperture 122 engages the toothed profile 142 of the retaining ring 140. As described above, the retaining ring 140 includes a narrow end 150 that is positioned above the wide end 152 when installed to the post assembly 110, accordingly, when the aperture 122 is lowered onto the retaining ring 140, the wide end 152 may create an interference fit with the aperture 122.
As both the aperture 122 and the retaining ring 140 include the toothed profiles 124, 142, respectively, when the aperture 122 is initially lowered onto the retaining ring 140, the end surfaces of the teeth 143 of the retaining ring 140 may contact the end surfaces of the teeth 125 of the aperture 122, preventing the aperture 122 from being seated to the retaining ring 140. A user may subsequently rotate the retaining ring 140 such that the teeth 143 of the retaining ring 140 are positioned between the teeth 125 of the aperture 122, allowing the aperture 122 to be lowered onto the retaining ring 140. In this way, the toothed profile 124 of the aperture 122 and the toothed profile 142 of the retaining ring 140 may assist in preventing the aperture 122 from being lowered onto the retaining ring 140 without manipulation/rotation of the retaining ring 140, which may assist in the assembly of the modular storage assembly 100. For example, by preventing the aperture 122 from being lowered onto the retaining ring 140, the toothed profiles 124, 142 may allow a user to selectively move the retaining ring 140 (and accordingly the shelf 120) along the post assembly 110 to a desired height before the shelf 120 is seated and selectively coupled to the retaining ring 140. Once seated, the shelf 120, retaining ring 140 and corresponding post assembly 110 remain snugly interconnected.
Referring to FIG. 12, the modular storage assembly 100 is schematically depicted with a plurality of door members 162 coupled to the storage rack 102 to form a storage cabinet 104. Some of the door members 162 may be pivotally coupled to the post assemblies 110 to form a door assembly 160 that may be selectively opened and closed to permit access to an interior of the modular storage assembly 100. While in the embodiment shown in FIG. 12, the shelves 120 and the door members 160 form an enclosed modular storage assembly 100, it should be understood that one or more of the shelves 120 and/or one or more of the door members 160 may be omitted from the modular storage assembly 100. In this way, post assemblies 110, the shelves 120, and the door members 160 may be assembled to form a storage bin with an open top, and/or a storage cabinet with one or more open sides. By forming a storage cabinet 104 or storage bin, the modular storage assembly 100 may be suitable for storing round or spherical objects, such as basketballs, soccer balls, or the like.
Referring to FIGS. 13A and 13B, a front and a rear view of a door panel 162 are schematically depicted, respectively. The door panel 162 includes a panel member 163, a pair of hinges 164 positioned on one side of the panel member 163, and a central hinge 166 positioned on a side of the panel member 163 opposite of the pair of hinges 164. The pair of hinges 164 and the central hinge 166 are configured to engage the post assembly 110 (FIG. 12) to couple the door panels 162 to the post assembly 110. In embodiments, the central hinge 166 is positioned on the door panel 162 in the vertical direction such that the central hinge 166 of one door panel 162 may be positioned between a pair of hinges 164 of an adjacent door panel 162 on the post assembly 110, as shown in FIG. 12. In this way, adjacent door panels 162 may form an enclosed storage cabinet. In embodiments, the door panels 162 are formed of a resin material, and may be formed through a molding process. In other embodiments, the door panels 162 may be formed of any suitable material, such as a polymer, a composite, or the like, and may be formed through any suitable manufacturing process. In some embodiments, the door panels 162 may be formed of the same material as the shelves 120, the post members 112, and the retaining rings 140. In other embodiments, the door panels 162, the shelves 120, the post members 112, and the retaining rings 140 may be formed from different materials and/or different combinations of materials. In addition, the door panels 162 can be made with the same dimensions as each other, such that a left door panel and a right door panel are exactly the same. This saves manufacturing and inventory costs.
Referring to FIG. 14, an exploded view of a door assembly 160 is schematically depicted. The door assembly 160 generally includes two door panels 162, a hasp member 170, and a latching post 180. The hasp member 170 is configured to engage the central hinge 166 of one of the door panels 162, and the latching post 180 is configured to engage the pair of hinges 164 of the other door panel 162. The hasp member 170 and the latching post 180 may be selectively coupled to and may be removable from the central hinge 166 and the pair of hinges 164, respectively, such as through an interference fit. In embodiments, the hasp member 170 and the latching post 180 are formed of a resin material, and may be formed through a molding process. In other embodiments, the hasp member 170 and the latching post 180 may be formed of any suitable material, such as a polymer, a composite, or the like, and may be formed through any suitable manufacturing process. In some embodiments, the hasp member 170 and the latching post 180 may be formed of the same material. In other embodiments, the hasp member 170 and the latching post 180 may be formed from different materials and/or different combinations of materials.
Referring to FIG. 15, a latching post 180 is depicted in isolation. The latching post 180 may have a generally cylindrical shape that is similar to the shape of the post members 112 (FIG. 3A). The latching post 180 may further include one or more annular grooves 182 that extend outward from the latching post 180. The annular grooves 182 may assist in maintaining the position of the latching post 180 in the vertical direction when the latching post 180 is coupled to the pair of hinges 164 (FIG. 14). The latching post 180 further includes a staple 184 that extends outward from the latching post 180. The staple 184 may be configured to receive a lock or the like to selectively prevent access to the modular storage assembly 100 (FIG. 12).
Referring to FIGS. 16A and 16B, a front and a rear view of the hasp member 170 are schematically depicted, respectively. The hasp member 170 includes a post 172, flanges 173 positioned on opposite sides of the post 172, and a hasp 174 that defines a slot 176. The post 172 is configured to be engaged with and selectively coupled to the central hinge 166 (FIG. 13A). The flanges 173 are positioned on opposite sides of the post 172 and extend outward from the post 172. The flanges 173 may assist in retaining the vertical position of the hasp member 170 with respect to the central hinge 166 (FIG. 13A) when the hasp member 170 is installed to the central hinge 166. The hasp 174 extends outward from the post 172 and is configured to engage the latching post 180. The hasp 174 may include a concave shape that is complementary to the cylindrical shape of the latching post 180. The slot 176 extends through the hasp 174 and is positioned to align with the staple 184 when the hasp member 170 and the latching post 180 (FIG. 15) are installed to respective door panels 162.
Referring to FIGS. 17A and 17B, a front view and a rear view of the door assembly 160 are schematically depicted, respectively. The door assembly 160 is repositionable between a closed position, in which the staple 184 of the latching post 180 is positioned within the slot 176 (FIG. 16A) of the hasp member 170 as shown in FIG. 17A, and an open position, in which the staple 184 is spaced apart from the slot 176 of the hasp member 170. In the closed position, a lock or the like can be positioned through the staple 184 to prevent either of the door panels 162 from rotating about the post assemblies 110 (FIG. 12) into an open position. In this way, the hasp member 170 and the latching post 180 may selectively restrict access to an interior of the storage cabinet 102. This may be advantageous in the case of storage of potentially dangerous tools or chemical products. For example, a consumer may wish to lock pesticides in the storage cabinet 102 in a garage to prevent children from gaining access.
