The present application relates to a storage container and a storage system including a stack of such storage containers.
One aspect of the present invention relates to a storage system comprising a plurality of stackable storage containers arranged in a vertical stack. The number of containers in the stack may be as few as two, and there is no upper limit. Each of the containers comprises (i) a drawer having a bottom wall and a peripheral wall defining a storage space for receiving articles, and an upwardly facing opening for accessing the storage space, and (ii) a drawer housing having at least an upper wall. The drawer is slidably mounted to the drawer housing for movement between (a) a retracted position wherein the drawer is positioned beneath the upper wall and (b) an extended position wherein the drawer is moved outwardly from beneath the upper wall, thereby allowing access to the storage space therein through the upwardly facing opening. The drawer housing is constructed to enable at least the upper wall of the drawer housing to be pivoted between (a) a closed position closing the upwardly facing opening of the drawer in its retracted position and (b) an open position uncovering the upwardly facing opening of the drawer in its retracted position. Each container also further comprises at least one upper coupling on an upper portion of the storage container, at least one lower coupling on a lower portion of the storage container, and a carrying handle for enabling the user to carry the storage container. The upper and lower couplings of each container are constructed such that, for each pair of vertically adjacent storage containers in the stack, (a) the upper coupling of a lower storage container of the pair is engaged in an interlocked relation with the lower coupling of an upper storage container of the pair to secure the storage containers of the pair together, and (b) the upper and lower couplings of the vertically adjacent storage containers of the pair can be disengaged to enable separation of the storage containers of the pair.
Another aspect of the invention relates to a storage container for stacking together with one or more similar storage containers. The storage container comprises a drawer having a bottom wall and a peripheral wall defining a storage space for receiving articles, and an upwardly facing opening for accessing the storage space. A drawer housing has at least an upper wall and the drawer is slidably mounted to the drawer housing for movement between (a) a retracted position wherein the drawer is positioned beneath the upper wall and (b) an extended position wherein the drawer is moved outwardly from beneath the upper wall, thereby allowing access to the storage space therein through the upwardly facing opening. The drawer housing is constructed to enable at least the upper wall of the drawer housing to be pivoted between (a) a closed position closing the upwardly facing opening of the drawer in its retracted position and (b) an open position uncovering the upwardly facing opening of the drawer in its retracted position.
The container also includes at least one upper coupling on an upper portion of the storage container and at least one lower coupling on a lower portion of the storage container. The upper coupling is constructed to be (a) engaged in an interlocked relation with a lower coupling of a similar storage container stacked atop the storage container to thereby secure the storage container and the similar storage container stacked atop thereof together, and (b) disengaged from the lower coupling of the similar storage container stacked atop the storage container, thereby allowing the storage container and the similar storage container stacked atop the storage container to be separated. The lower coupling is constructed to be (a) engaged in an interlocked relation with an upper coupling of a similar storage container stacked below the storage container to thereby secure the storage container and the similar storage container stacked below the storage container together, and (b) disengaged from the upper coupling of the similar storage container stacked below the storage container, thereby allowing the storage container and the similar storage container to be separated. The container also further comprises a carrying handle for enabling a user to carry the storage container.
Other objects, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
The drawer housing 14 in the illustrated embodiment is formed from plastic by injection molding and has at least an upper wall 26. The drawer 12 is slidably mounted to the drawer housing 14 for movement between (a) a retracted position wherein the drawer 12 is positioned beneath the upper wall 26 and (b) an extended position wherein the drawer 12 is moved outwardly from beneath the upper wall 26, thereby allowing access to the storage space 20 therein through the upwardly facing opening 22. The retracted position is shown, for example, in
In the illustrated embodiment, the drawer housing 14 has a pair of side walls 28 extending downwardly from the upper wall 26 on opposing sides of the drawer 12. Further, in the illustrated embodiment the upper wall 26 and the side walls 28 of the drawer housing 14 are fixed together, preferably by being molded together as a single piece, so that the side walls 28 are pivoted along with the upper wall 26 between the open and closed positions thereof. A recess 30 is provided on each side wall 28 to act as handles for facilitating carrying the container 10 in two hands, or for raising the housing 14 to establish the open position of the upper wall 26. As an alternative, the upper wall could be pivotally mounted to the side walls 28. Also, the presence of the side walls 28 is not necessary, and instead is only preferred. Thus, the drawer housing 14 may have any suitable construction or configuration and the invention is not limited to the one illustrated.
As seen for example in
Each side wall 28 of the drawer housing 14 also includes a support flange 36 extending inwardly adjacent a front end of the drawer housing 14. These flanges 36 are provided by plate-like walls that extend inwardly from the front end of the drawer housing 14. The drawer 12 also has a pair of support ridges 38 extending longitudinally on each side thereof. The support ridges 38 are supported by the support flanges 36 to support the drawer 12 as it moves between the retracted and extended positions thereof Because the flanges 36 are made of plastic material and have a plate-like wall construction, the support flanges 36 are resiliently deflectable for clearing the support ridges 38 as the drawer housing 14 is pivoted to establish the open position of the upper wall 26. Specifically, the flanges 36 engage the ridges 38 and inhibit pivoting of the drawer housing 14 even when the latches 40 (discussed below) are in their released position, but will be deflected by forcing the drawer housing 14 upward. Conversely, upon moving the drawer housing 14 back down to the closed position of the upper wall 26, the angled lower surfaces of the flanges 36 will engage the ridges 38 and the flanges 36 will deflect inwardly and resiliently return to their supporting relation beneath the ridges 38. The presence of the flanges 36 and ridges 38 is not necessary, and instead is only preferred. Thus, the drawer 12 and drawer housing 14 may have any suitable construction or configuration and the invention is not limited to those illustrated.
The container 10 further comprises a pair of latches 40. The latches 40 are movable between (a) a latching position releasably latching the drawer 12 in the retracted position thereof, and (b) a released position enabling the drawer 12 to be moved to the extended position thereof. Further, the latches 40 in the latching position thereof also releasably latch the upper wall 26 in its closed position, and in the released position thereof enables the upper wall 26 to be moved to its open position. In the illustrated embodiment, the latches 40 are slidably mounted on a front face of the drawer 12 for lateral movement between the latched and released positions thereof. Further, in the illustrated embodiment, the structure which the latches 40 engage is the upper wall 26 on the drawer housing 14. The upper wall 26 has a front edge 42 with (a) latch engaging portions 44 each having a lip 46 protruding upwardly therefrom and (b) recesses 48 adjacent the latch engaging portions 44. The recesses 48 are positioned such that, when the drawer 12 is in the retracted position thereof and the upper wall 26 is in the closed position thereof, the latches 40 in their released positions are received in the recesses 48, and then can be moved laterally outwardly onto the latch engaging portions 44 and the lips 46 thereof to affect the latched positions thereof. Any suitable construction or configuration may be used for securing the drawer 12 in its retracted position, and/or the upper wall 26 in its closed position, and the invention is not intended to be limited to the illustrated embodiment.
The container 10 also includes at least one upper coupling 50 on an upper portion of the storage container 10 and at least one lower coupling 52 on a lower portion of the storage container 10. As can be appreciated best from
In the illustrated embodiment, the at least one lower coupling includes 52 a plurality of hooks 54 on lower portions of the storage container 10 and the at least one upper coupling 50 includes a plurality of receptacles 56 on upper portions of the storage container 10. The receptacles 56 are constructed to be (a) engaged in an interlocked relation with hooks 54 of a similar storage container stacked atop the storage container 10 to thereby secure the storage container 10 and the similar storage container stacked atop thereof together, and (b) disengaged from the hooks 54 of the similar storage container stacked atop the storage container 10, thereby allowing the storage container 10 and the similar storage container stacked atop the storage container 10 to be separated. Likewise, the hooks 54 are constructed to be (a) engaged in an interlocked relation with receptacle 56 of a similar storage container stacked below the storage container 10 to thereby secure the storage container 10 and the similar storage container stacked below the storage container 10 together, and (b) disengaged from the receptacles 56 of the similar storage container stacked below the storage container 10, thereby allowing the storage container 10 and the similar storage container to be separated.
As can be appreciated from
Further, integrally formed plastic in the illustrated embodiment, the upper portions of the side walls 28 each include upstanding walls 58 defining recessed wells 60 and the receptacles 56 are formed through walls 62 located within the recessed wells 60. The hooks 54 are integrally formed plastic and extend downwardly from lower portions of the side walls 28. Any suitable construction or configuration may be used for securing storage containers 10 in a stack, and the invention is not intended to be limited to the illustrated embodiment.
The container 10 also further comprises a carrying handle 64 for enabling a user to carry the storage container 10. Preferably, the carrying handle 64 is pivotably connected to a front wall of the drawer 12 for facilitating movement of the drawer 12 between the retracted and extended positions thereof.
With this general construction, a plurality of storage containers 10, which may be any number of two or more containers 10, may be vertically arranged in a stack 100 to define a storage system 102 as shown in
The invention is particularly advantageous for use in modular storage whereby a user can store a number of articles in the containers 10 and have the advantages of a system 102 that stores a wide variety of articles, but enables each container 10 to be separated for transporting only selected articles in any given container 10. For example, a user could store a number of different tools and tool accessories in the storage containers 10, and when the user needs to access the tools, he can either (a) leave the containers 10 in the stack 100 and access the containers 10 by the drawers 12, or (b) separate a desired container 10 with the particular tools he/she needs and transport that container 10 to a work location. The tool context is not limiting, and the invention could be applied to contexts such as children's toys, arts and crafts, sewing and other domestic activities, or fishing and other recreational activities, etc.
The foregoing illustrated embodiment has been provided solely for illustrating the structural and functional principles of the present invention and is not intended to be limiting. To the contrary, the present invention is intended to encompass all modifications, substitutions, alterations, and equivalents encompassed within the spirit and scope of the following claims.
