This invention relates to storage bins and, more particularly, to multi-function storage bins that can be interlocked with one another when the bins are stacked on top of one another or nested together.
Storage bins or containers are used to store loose objects such as screws, nuts, bolts, nails, pegs, etc. Storage bins may be hung from or mounted to a perforated support panel or perf-board. Storage bins also may be stacked on top of one another or nested together.
Known storage bins of one type generally have two side walls separated by front, back and bottom surfaces. The top edges of the side walls typically include a ledge and the bottoms of the side walls include feet. Several bins can be stacked together by resting the feet of one bin on the ledges of another bin, and unstacked by lifting the bins off of each other. Due to the relative ease with which the bins can be stacked and unstacked, a stack of bins is relatively cumbersome or difficult to move because the bins easily separate if the stack is toppled or knocked over, causing the contents of the bins to spill and/or intermix. Thus, in order to move the bins they must either be lifted by the bottommost bin in the stack or moved individually.
Stackable storage bins of another known type incorporate slotted feet that are configured to engage pins or tabs in the area of the ledge. One such bin incorporates two triangular tabs at the ledge. Inserting the pins into the slots in the feet provides guidance for stacking the bins, but does provide suitable retention. As a result, these bins suffer from the same problems as their unslotted counterparts, namely, they are difficult to move because they separate easily if they are knocked over.
Other storage bins are designed to nest together in order to consolidate space, for example, when shipping the bins. Like the stackable bins, the nesting bins have a ledge along the upper edges of the side walls. Additionally, the side walls of the bin have a horizontal ridge that separate the bin into an upper portion and a slightly narrower lower portion. The bins are nested together by placing one bin into another such that the narrower bottom portion of one bin rests in the wider, upper portion of a second bin. When the bins are nested together, the ridge of the upper bin is supported by the ledge of the lower bin. Known storage bins with this configuration do not have feet and therefore cannot be stacked on top of one another. The bins can be separated or pulled apart by lifting one bin from another bin, and consequently, the bins may be difficult to move because they easily separate if the stack of nested bins is knocked over. Furthermore, given the flexibility of the side walls, the bins sometimes may undesirably collapse into one another, for example, if a heavy load is placed an upper bin.
Nesting bins of another variety have a pair of feet that are insertable into a channel in the side walls. These bins are nested together by inserting the feet of one bin into a respective channel of another bin. In order to hold the feet in place, the width of the channel is slightly narrower at the channel entrance or opening. Thus, the side walls of the channel must be flexed slightly outwardly to allow the feet to pass through the opening and into the channel. The repeated flexing of the side walls creates stress in the areas of the openings and eventually may cause the bin to crack, split, break or otherwise fail.
Briefly, an aspect of the invention relates to improvements in storage bins that overcome the previously mentioned drawbacks.
According to an aspect of the invention, a storage bin includes a pair of side walls separated from each other by a rear portion and a bottom portion, the rear portion and the bottom portion extending between the side walls. One or more channels in each side wall have a point of entry and a tab partially blocking a portion of at least one oh the channels such that the tab impedes the removal of a foot of a second storage bin when the foot is inserted in the channel.
In an embodiment of the storage bin, the channel extends from a front portion of the storage bin towards the rear portion of the storage bin, and the point of entry is near the front portion of the storage bin.

According to another aspect of the invention, a storage bin includes a pair of side walls separated from each other by a rear wall and a bottom surface, the rear wall and bottom surface extending between the side walls. An upper channel in each side wall, has a point of entry and a tab partially blocking the point of entry. The tabs impede removal of a pair of feet on a second storage bin when the feet are inserted into the upper channels to stack the storage bins on top of one another. A lower channel in each side wall has a point of entry and a tab partially blocking the point of entry such that the tabs impede removal of the feet on the second storage bin when the feet are inserted into the lower channels to at least partially nest the storage bins together.

In an embodiment of the storage bin, at least one upper or lower channel is tapered such that the channel is wider near the point of entry and narrower near the rear portion of the storage bin.
In an embodiment of the storage bin, the tab extends from the lower front edge of the channel to restrict the horizontal movement of the foot in the channel.
In an embodiment of the storage bin, the upper wall of the at least one channel further includes a lateral portion to restrict the vertical movement of the foot in the channel.
In an embodiment of the storage bin, the lateral portion is a flange-like lateral extension of the side walls.
In an embodiment of the storage bin, the upper wall of at least one channel is angled relative to the lower portion of the channel.
According to another aspect of the invention, a storage bin includes a pair of side walls separated from each other by a rear portion and a bottom portion, the rear portion and bottom portion extending between the side walls, and a channel in each side wall, each channel having an upper portion having an upper front edge and a lower portion having a lower front edge. A point of entry defined by the upper front edge and the lower front edge, and a tab at least partially blocks the point of entry of at least one channel such that the tab impedes removal of a foot on a second storage bin when the foot is inserted into the channel.
In an embodiment of the storage bin, the tab extends from the lower front edge of the channel.
In an embodiment of the storage bin, the upper front edge is offset from the lower front edge.

These and further features of the present invention will be apparent with reference to the following description and drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the invention may be employed, but the invention is not limited correspondingly in scope. Rather, the invention includes all changes, modifications and equivalents coming within the spirit and terms of the claims.
Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments.
In the following description, with reference to the drawings, like reference numerals are used to refer to like elements throughout. It will be appreciated that the drawings are not necessarily to scale. Certain terminology is used herein to describe the different embodiments of the invention. Such terminology is used only for convenience when referring to the figures. For example, “vertically” or “horizontally” merely describe the configuration shown in the figures. The components can be oriented in any direction and the terminology should therefore be interpreted to include such variations.
With additional reference to
Similarly, with additional reference to
The channel and tab configuration and the combination of the lateral and vertical forces to remove the feet 20 of the upper storage bin 22 from the upper channel 13 or lower channel 14 of the lower storage bin 23 allows the storage bins to be interlocked with one another when stacked or nested. This further allows the storage bins to be moved easily without separating from one another, and prevents or inhibits the accidental sliding or removal of the feet 20 from the channels. The channel and tab configuration also reduces the risk that the bins will fall or collapse into one another, tip over and separate, or crack from placing unnecessary stress on the side walls of the bin when inserting and removing the feet from the channels. These as well as other features of the storage bin are described more fully below.
Referring generally to
The pair of upper channels 13, also referred to as stacking channels, are disposed on or molded in the sides 11, 12 of the storage bin 10. The upper channels 13 are used to stack two storage bins on top of one another as described above with respect to
Although the storage bin 10 is shown with both upper channels and lower channels 14, it will be appreciated that the bin 10 alternatively may have only a single pair of channels. For example, if the storage bin only has a pair of upper, stacking channels 13, several storage bins could be stacked on top of one another, but not nested together. Likewise, if the storage bin only has a pair of lower, nesting channels 14, then several bins could be nested together, but not stacked on top of one another. If desired, the storage bin also may have more than two pairs of channels. It will be appreciated that either or both of the channels can be located at any desired height to achieve any variation and/or combination of nesting and/or stacking.
The front portion of the upper channel 13 is shown in more detail in
The tab 16 is molded or otherwise attached to the lower front edge 36 of the upper channel 13. The tab 16 partially obstructs or blocks the point of entry 15. A rear face 37 of the tab 16 inhibits the horizontal movement of the foot 20 when the foot 20 is fully inserted in the upper channel 13. Sliding the foot 20 from the upper channel 13 is impeded by the tab 16, thus tending to block removal of the foot 20 from the channel 13 unless the foot 20 is lifted vertically and slid over the tab 16.
Referring to
A tab 18 extends from the front edge 43 of the lower wall 42 to partially block the point of entry 17. As described above with respect to the upper channel 13, the tab 18 at the lower front edge 43 has a rear face 44. The rear face 44 of the tab 18 inhibits the horizontal movement of the foot when the foot is fully inserted in the lower channel 14. Sliding the foot 20 from the lower channel 14 is impeded by the tab 18, thus tending to block removal of the foot 20 from the channel 14 unless the foot 20 is lifted vertically and slid over the tab 18.
The two forces in different directions (e.g., one up and one out) that are required to remove the feet 20 from the channels 13, 14 reduce the likelihood that several stacked or nested storage 22, 23 bins will separate from one another should they be knocked or toppled over, and also reduces the likelihood that the bins may be accidentally slid apart.
In one embodiment, the offset between the upper 34 and lower 36 edges of the upper channel 13 and the upper 41 and lower 43 edges of the lower channel 14 is approximately 1/8 inch, however it will be appreciated that the size of the channels, and points of entry may be increased or decreased to accommodate the feet of larger or smaller storage bins or feet having different profiles, etc.
Although the tabs 16,18 are shown extending vertically to partially block a portion of the points of entry 15, 17 to the upper 13 and lower channels 14, it will be appreciated that the tabs 16, 18 may be oriented at other positions on or within the channel. For example, the tabs may extend from the front edges 34, 41 of the upper walls 33, 40 of the channels 13,14 or may be disposed at another position along the length of the channels. Although shown as a tab 16, 18 partially blocking the point of entry 15, 17, it will be appreciated that another implement may be used to inhibit or interfere with the removal of the feet from the channels. Additionally, one or more tabs may be incorporated into the channel or may block part of the channel, as may be desired.
Referring to
The bottom surface 47 of the foot 20 is generally planar along the length of the bin 10. The bottom surface 47 rests on the lower wall 35 of the upper channel 13 when two or more bins are stacked on top of one another (
The foot 20 also has a front face 48. When the foot 20 is fully inserted into the upper channel 13 and the bins are stacked together, the front face 48 engages or abuts the rear face 37 of the tab 16 to prevent or to impede the foot 20 from sliding out of the channel 13. To remove the foot 20 from the channel 13, a vertical lifting force is required to raise the bottom 47 of the foot 20 over the tab 16. The front face 48 of the foot 20 and rear face 44 of the tab 18 interact in a similar manner when the bins are nested together, and a vertical force is required to lift the bottom 47 of the foot 20 over the tab 18 to remove the foot from the channel 14. The front face 48, therefore, prevents or inhibits accidental removal of the feet from the channels.
The flared foot 20 is insertable into a variety of different profile channels. For example, the channel may have a sloped profile, a rectangular profile or a profile that has a sloped component and a lateral component similar to the profile of the flared foot 20. Although illustrated as having approximately a 45-degree slope, it will be appreciated that the sloped portion 45 of the foot 20 may be any desired angle, for example, to accommodate different channel profiles, or to vary the distribution of the forces in the feet and channels, etc.
Referring now to
As described above, the point of entry 15 to the upper channel 13 is defined by the front edge 34 of the upper wall 33 and the front edge 36 of the lower wall 35. The upper front edge 34 is offset from lower front edge 36 to allow greater freedom of movement for inserting and removing the foot 20 from the channel 13.
The lower channel 14 extends generally along the length of the storage bin 10 and has the same general profile as the upper channel 13, including a tapered region near the point of entry 17 for facilitating the insertion and removal of the foot 20 from the lower channel 14 and an untapered region near the rear region 51 of the bin. To further facilitate insertion and removal of the foot 20 from the lower channel 14, the upper front edge 41 of the channel 14 is sloped. The combination of the front portion 50 of the channel 14 and sloped upper front edge 41 allow greater freedom of movement to lift the foot 20 over the tab 18 when the foot 20 is inserted or removed from the lower channel 14. It will be appreciated that the front edge 41 need not be sloped, as shown in
The rear region 51 of the lower channel 14, which is not tapered, restricts the movement of the foot 20 when the foot 20 is fully inserted into the lower channel 14. As described above with respect to the upper channel 13, the rear region 51 may be narrow enough to create a friction fit with the foot 20.
As described above with respect to the upper channel 13, the point of entry 17 to the lower channel 14 is defined by the front edge 41 of the upper wall 40 and the front edge 43 of the lower wall 41. The upper front edge 41 is offset from lower front edge 43 to allow greater freedom of movement for inserting and removing the foot 20 from the lower channel 14.
The lower channel 14 also is configured to receive a foot 20 having a flared cross-section. The lower channel 14 has a sloped upper wall 52 and a lateral upper wall 53. When a flared foot 20 is fully inserted in the channel 14, the sloped upper wall 52 cooperates with the sloped portion 45 of the foot 20 to center the foot 20 in the lower channel 14, and to evenly distribute any lifting forces in the foot 20 and the lower channel 14. The lateral upper wall 53 cooperates with the lateral portion 46 of the flared foot 20 in the same manner. The feet of other storage bins, such as those described in the Background, also may be inserted and retained in the channels 13, 14 of the storage bin 10 as described herein. It also will be appreciated that while the upper channel 13 and lower channel 14 have been described as having specific configurations, the upper channel 13 may be flared and lower channel 14 may be rectangular, or, the channels may have a different profile, as will be appreciated by one of skill in the art. Furthermore, the upper walls may be configured to allow feet with a multitude of different profiles or cross-sections to be inserted and retained in the channel 14, for example, feet with triangular, rectangular, or circular cross-sections, etc., may be inserted and generally retained in the channels.
With additional reference to
The foot 20 initially is inserted into the upper channel 13 at an angle, e.g., along the angle of the tapered front region 50 of the upper channel 13 (
As shown in
As shown in
Thus, the stacked bins 22, 23 are interlocked with one another and separating the bins requires a combination of a vertical force to lift the bottom 47 of the foot 20 over the tab 16 and a horizontal force to slide the foot 20 from the channel 13. The combination of the vertical and horizontal movement necessary to remove the foot 20 from the upper channel 13 keeps the bins together and decrease the likelihood that the bins will separate during normal usage or if the stack of bins tips or topples over.
The length of the upper channel 13 is slightly greater than the length of the foot 20 such that there is a small gap between the front face 48 of the foot 20 and the rear face 37 of the tab 16 when the foot 20 is fully inserted into the upper channel 13. The gap allows the foot 20 to move slightly in the upper channel 13, which facilitates lifting the foot 20 over the tab 16 to separate one bin from another. In one embodiment, the gap between the front face 48 of the foot 20 and the rear face 37 of the tab 16 is between ⅛-inch and 1/16-inch, however, it will be appreciated that the clearance or gap may be larger or smaller based upon the size of the storage bins and the tolerance needed to insert and remove the foot from the channel.
With additional reference to FIGS. 3 and 8A-8C, several storage bins 22, 23 also are nestable within each other by sliding the foot 20 of one storage bin 22 into the lower or nesting channel 14 of a second bin 23. As described above, the offset and taper of the channel 14 facilitate insertion of the foot 20 over the tab 18 and into the lower channel 14. With specific reference to
Referring specifically to
Continuing to refer to
The nested bins 22, 23 interlock with one another and separating the bins ordinarily requires a combination of a vertical force to lift the bottom 47 of the foot 20 over the tab 18 and a horizontal force to slide the foot 20 out of the channel 14. The combination of the vertical and horizontal movement necessary to remove the foot from the lower channel keep the bins together during normal usage and decreases the likelihood that the bins will separate if they tip over.
Like the upper channel 13, the length of the lower channel 14 is slightly greater than the length of the feet 20 such that there is a small gap or clearance between the front face 48 of the foot and the rear face 44 of the tab 18. The gap facilitates the insertion and removal of the foot 20 from the channel 14.
Although the figures illustrate the stacking and nesting of bins that are the same size, it will be appreciated that different sized bins may be stacked on top of one another or nested together. For example, a shorter bin may be stacked on top of or nested within a larger storage bin, etc. Although illustrated with respect to two bins, it will be appreciated that multiple bins, including the same and different sized bins, may be stacked on top of each other and/or nested together.
Referring back to
The storage bin 10 also has a label holder 63 disposed or formed on the front portion 30. A label or card is insertable into the holder 63 and may be used to label or identify the contents of the storage bin 10. The holder 63 has an opening 64 into which an identification card may be inserted. The identification card is supported by the card holder sides 65, 66 and bottom 67. The label or identification card may be removed from the holder 63 by sliding the card through the opening 64, allowing the identification card to be replaced or changed as desired.
A hanger 70 or other hanging implement, is attached or molded to the top edge 71 of the rear portion 32 of the storage bin 10 to allow the bin to be hung. For example, the storage bin may be hung from louvered panels or racks, bin rails, perforated panels, perf-board, or on cabinet doors or walls, etc. The hanger 70 may be molded to the top edge 71 of the rear portion 32, as shown in
The storage bin 10 may be constructed from a rigid and/or flexible material such as metal or plastic and may welded or formed by an injection molding process. Some suitable materials include polyvinylchloride (PVC), polyethylene, or polypropylene, however, other suitable material may be used based on the size of the bins and the desired strength of materials, etc., as will be appreciated by one of skill in the art. While the storage bin has been described as being constructed from materials that form solid walls, it will be appreciated that the storage bins may instead be constructed from other materials including for example, flexible materials that may be stretched over a solid frame, metal, or a combination thereof, such as, mesh stretched over rigid frame.
The bins also may vary in shape, including height, width and depth. Additionally, the height of the front portion 30 is less than the height of the side walls 11, 12 and rear wall 32 to provide a space for access to the lower bins, for example, if several bins are stacked on top of one another.
Although not shown in the figures, a flat cover may be slidably inserted into the channels 13, 14 to cover the storage bin 10 and protect the stored items from dust or other contaminants as well as to prevent the contents of the storage bins from spilling and/or intermixing. The cover may, for example, be manufactured from a clear, rigid material that allows the contents of the storage bin to be seen when the bin is covered. Alternatively, the cover may be constructed from a rigid frame that supports or stretches a flexible material, such as plastic or fabric across the opening of the storage bin.
The cover is insertable into the lower channel 14 to substantially enclose the lower half of the bin cavity. Alternatively, the cover may be inserted into the upper channel 13 to substantially enclose the top of the bin cavity. In yet another alternative, the cover may have a flap to cover the open front portion of the storage bin 10 when the cover is inserted into the upper channel 13. The flap may be rigidly attached or molded to the cover or alternatively may be attached via a hinge or a flexible member such that the flap can be opened and/or closed as desired to access the contents of the storage bin 10. The flap also may have a securing member to maintain the flap in a closed position. Possible securing members include, for example, Velcro, a latch, a hook or another suitable mechanism. Alternatively, the flap may be configured slide along the inside of the front portion 30 or to be inserted and/or secured into the label holder 63.
The storage bin 10 also may be fixed or attached to a surface, for example, a work bench or table. A track or channel, shaped like the upper or lower channels described above, e.g., a tapered channel having an offset, point of entry, and a tab partially blocking the front edge of the point of entry, may be integrated or attached to the work surface. The channel may be molded to the work bench or attached to the work bench by screws, nails, glue, etc.
The feet of the storage bin 10 may be inserted into the channel at a slight angle with the configuration of the channel and tab limiting the vertical and horizontal movement of the foot in the channel, as described above. Additional storage bins may be stacked on or nested in the storage bin that is attached to the work surface. By attaching the bins to the work surface, the bins are less likely to tip or be accidentally knocked over. It also will be appreciated that the tracks may be inclined relative to the surface of the work bench thereby causing the contents of the storage bins to migrate or slide towards the front of the bin. Similarly, the storage bins may be arranged on a shelving unit or a separate rack, for example a gravity shelf having, which have inclined tracks or channels into which the feet of storage bins may be slid.
It also will be appreciated that the bins may be standalone units and may, for example, be placed in a drawer or cabinet or on a cart, shelf, rack, gravity shelf, etc.
Although particular embodiments of the invention have been described in detail, it is understood that the invention is not limited correspondingly in scope, but includes all changes, modifications and equivalents coming within the spirit and terms of the claims.
