DETAILED DESCRIPTION

FIG. 1 illustrates a storage device system 10 including a soft-sided storage device 14, such as soft-sided bag, removably coupled to a hard-sided or rigid storage device 18, such as a rigid storage case (e.g., a rigid tool box or organizer).

With reference to FIGS. 2-4, the bag 14 includes a rigid or hard bottom member 22 (e.g., thermoform plastic, etc.) and flexible sidewalls 26 cooperating to define a storage compartment 30. The sidewalls 26 define an open top 34 for access to the storage compartment 30. A handle 38 is connected between opposite sidewalls 26 and is engageable by a user to carry the bag 14.

One or more interface or connection projections 46 are provided on the bottom member 22. In the illustrated embodiment, each projection 46 extends from a bottom surface 50 of the bottom member 22 and is configured to cooperate with a connection recess 54 (FIGS. 5-6) on the storage case 18 to interface and connect the bag 14 to the storage case 18. In the illustrated embodiment, each projection 46 is formed integrally with the bottom member 22, for example, in a thermoforming process. Each projection 46 has a channel 58 on each side of the projection 46 extending parallel to a longitudinal axis A of the bottom member 22, as best shown in FIG. 4. Each channel 58 has a front, open end 62 and a back, closed end 66 along the axis A. Each projection 46 has a planar surface 70 with a generally rectangular shape. In other embodiments, the planar surface 70 may be another shape, e.g., circular, triangular, etc. In the illustrated embodiment, there are six projections 46 arranged in three rows of two along the axis A. In other embodiments, the bag 14 may include fewer or more projections 46, and/or the projections 46 may be arranged in different patterns. The projections 46 are arranged such that the bag 14 can be supported on a surface by the projections 46 through contact with the planar surfaces 70.

The bag 14 further includes a latch assembly 78 including a latch member 82, as shown in FIG. 3. The latch assembly 78 is supported by the bottom member 22 within a latch passage 86 defined in the bottom member 22. The latch member 82 includes a grip portion 90 and an interference portion 94. The latch member 82 is slidingly movable along an axis perpendicular to the longitudinal axis A of the bottom member 22 within the latch passage 86. The interference portion 94 selectively protrudes from the latch passage 86 through a slot 98 defined in the bottom surface 50 of the bottom member 22. The interference portion 94 has a tapered surface 102 (FIG. 7) at a distal end thereof. The latch member 82 is movable between a first or locking position (FIG. 9) in which the interference portion 94 extends through the slot 98, and a second or unlocking position (FIG. 10) in which the interference portion 94 is retracted into the latch passage 86 and does not extend through the slot 98. The latch assembly 78 further includes a biasing member 106 (e.g., a compression spring) arranged to bias the latch member 82 into the locking position (FIG. 9). The latch member 82 may be urged against the biasing member 106 to the unlocking position (FIG. 10) by pushing on the grip portion 90. In the locking position, the interference portion 94 does not extend beyond the planar surfaces 70 of the projections 46.

With reference to FIGS. 5 and 6, the storage case 18 includes a base 114 and a top or cover 118. The cover 118 is movably coupled to the base 114 between a closed position (FIG. 5) and an open position (FIG. 11). In the illustrated embodiment, the cover 118 is pivotally coupled to the base 114 by a hinge 122. The cover 118 includes cover latches 126 to releasably secure the cover 118 in the closed position. The storage case 18 also includes a side handle 130 to facilitate independently carrying the storage case 18.

With continued reference to FIGS. 5 and 6, a top surface 134 of the cover 118 defines the connection recesses 54 that receive and cooperate with the projections 46. In the illustrated embodiment, the connection recesses 54 include two rows of two small recesses 54a corresponding to two rows of two projections 46 and one large recess 54b corresponding to a row of two projections 46. In other embodiments, the cover 118 may include different numbers of patterns of recesses 54, depending on the arrangement of the projections 46 on the bag 14. When the projections 46 are received in the connection recesses 54, the bottom surface 50 of the bottom member 22 is arranged to contact and be supported by the top surface 134 of the cover 118.

An interference projection or wing 142 extends into each connection recess 54 parallel to a longitudinal axis B of the cover 118 on opposite sides of the connection recess 54 from one end of the connection recess 54. Each of the wings 142 corresponds to and is configured to cooperate with a corresponding one of the channels 58 of the projection 46 received by the respective connection recess 54. Each of the wings 142 has a length that extends approximately half the connection recess 54 to define a first portion 146 of the connection recess 54 and a second portion 150 opposite the wings 142, which remains open. The second portion 150 of each connection recess 54 is sized to receive one of the projections 46 generally perpendicular to the longitudinal axis B into a first, disconnected position (FIG. 7). In the disconnected position, the projections 46 are oriented within the connection recesses 54 such that the open ends 62 of the channels 58 are nearer to the wings 142 than the closed ends 66. Once in the disconnected position, the bottom member 22 may be slid relative to the cover 118 parallel the longitudinal axes A, B in a first direction 152 toward the wings 142 such that the wings 142 are received within the channels 58 in a second, interfaced or connected position (FIG. 8). The wings 142 and the projections 46 engage within the connection recesses 54 to interface and connect the bottom member 22 with the cover 118 and prevent disconnection of the bottom member 22 from the cover 118, except in a second direction 154 opposite the first direction 152 and generally parallel to the longitudinal axes A, B. The wings 142 and the channels 58 engage one another perpendicular to the longitudinal axes A, B (i.e., perpendicular to the top surface 134 of the cover 118 and the bottom surface 50 of the bottom member 22) when carrying the bag 14 and the storage case 18 as a single unit via the handle 38 of the bag 14 (see FIG. 1).

With continued reference to FIGS. 5 and 6, the top surface 134 of the cover 118 further defines an interference or locking aperture 158. In the illustrated embodiment, the locking aperture 158 is located at one end of the cover 118. The end of the cover 118 has a sloped surface 162 adjacent the locking aperture 158. The locking aperture 158 is elongate and extends transverse to the longitudinal axis B of the cover 118 parallel to a short side of the cover 118. The locking aperture 158 is located such that when the bottom member 22 and the cover 118 are in the connected position, the locking aperture 158 is aligned with the interference portion 94 of the latch member 82. The locking aperture 158 is sized to receive and engage the interference portion 94 when the latch member 82 is in the locking position (FIG. 9). When the interference portion 94 is engaged with the locking aperture 158 in the locking position, the latch member 82 obstructs movement of the bottom member 22 relative to the cover 118 from the connected position to the disconnected position in the second direction 154, thereby inhibiting disconnection of the bag 14 from the storage case 18. In particular, the interference portion 94 interferes with the cover 118 within the locking aperture 158 such that the wings 142 cannot be removed from the channels 58 of the projections 46 in the second direction 154.

A user may couple the soft-sided bag 14 to the rigid storage case 18 to carry as a coupled unit by first, inserting the connection projections 46 of the bottom member 22 in a direction perpendicular to the cover 118 and into the second portion 150 of the connection recesses 54 of the cover 118 such that the cover 118 supports the bag 14 in the disconnected position (FIG. 7). The bottom member 22 and the cover 118 are oriented such their longitudinal axes A, B are parallel, and the latch assembly 78 is nearest the end of the cover 118 defining the locking aperture 158. The bag 14 (i.e., the bottom member 22) is then manually slid in the first direction 152 such that the wings 142 are received in the channels 58 through the open end 62 of the channels 58 until the wings 142 abut the closed end 66 of the channels 58 in the connected position (FIG. 8). As the bottom member 22 slides relative to the cover 118 from the disconnected position to the connected position, the latch member 82, which is biased into the locking position (FIGS. 7 and 9) by the biasing member 106, is urged into the unlocking position (FIG. 8) by the sloped surface 162 of the cover 118 until aligned with the locking aperture 158 when in the connected position. The biasing member 106 then automatically biases the latch member 82 back into the locking position (FIG. 9) in which the interference portion 94 is received in and engages the locking aperture 158. Alternatively, a user may urge the latch member 82 into the unlocking position (FIG. 10) by pushing on the grip portion 90 upwardly against the biasing force of the biasing member 106. The user holds the latch member 82 in the unlocking position while sliding the bag 14 in the first direction 152 from the disconnected position to the connected position. Once in the connected position (FIG. 10), the user may release the latch member 82, thereby allowing the latch member 82 to be biased into the locking position where the interference portion 94 is received in and engages the locking aperture 158. The interference portion 94 of the latch member 82 extends into the locking aperture, thereby inhibiting relative movement of the bag 14 and the storage case 18 in the second direction 154 parallel to the longitudinal axes A, B. Accordingly, the latch assembly 78 and the locking aperture 158 cooperate to secure the soft-sided bag 14 and the rigid storage case 18 in the connected position as a unit to be carried by the handle 38 of the bag 14. The handle 38 is positioned such that when the bag 14 and the storage case 18 are coupled as a unit, the handle 38 is above a center of gravity of the coupled unit.

When the soft-sided bag 14 and the rigid storage case 18 are coupled together, the user may quickly decouple them to carry or access each of the storage devices 14, 18 separately. The user first urges the latch member 82 into the unlocking position (FIG. 10) by pushing on the grip portion 90 upwardly against the biasing force of the biasing member 106. While holding the latch member 82 in the unlocking position, the user then slides the bag 14 relative to the cover 118 in the second direction 154 along the longitudinal axes A, B from the connected position (FIG. 8) to the disconnected position (FIG. 7). The wings 142 disengage from the channels 58 and the projections 46 are moved into the second portion 150 of the connection recesses 54, allowing the bag 14 to be disconnected in a direction away from and perpendicular to the top surface 134 of the cover 118.

The latch assembly 78 is dimensioned and constructed to be movable between the locking and unlocking positions to couple the bag 14 to the cover 118. The latch assembly 78 does not interfere with opening the storage case 18 so that the storage case 18 on the bottom will still be able to be opened with the soft-sided bag 14 attached to the cover 118.

It should be understood that, in other constructions, multiple latch assemblies 78 and corresponding locking apertures 158 may be provided on the bag 14 and the storage case 18. Such an arrangement may, for example, provide an increased connection between the storage devices 14, 18, balance or reduce the load on a given latch assembly, etc.

It should also be understood that, in other constructions, the latch assembly 78 and the locking aperture 158 may be reversed (e.g., the movable latch member 82 and the biasing member 106 may be supported on the cover 118 or the base 114 of the storage case 18, and the locking aperture 158 may be defined by the bottom member 22 of the bag 14). Additionally or alternatively, the relative locations of the projections 46 and the recesses 54 may be reversed (e.g., the projections 46 may extend from the cover 118 of the storage case 18, and the recesses 54 may be formed in the bottom member 22 of the soft-sided bag 14).

As shown in FIG. 1, the storage devices 14, 18 have approximately the same perimeter dimensions. There is one pair of latch assembly 78 and locking aperture 158 at one end of the storage devices 14, 18. However, in alternate embodiments, the storage devices 14, 18 may have different perimeter dimensions (e.g., the bag 14 is shorter than the storage case 18). In such embodiments, the bag 14 may have fewer projections 46 arranged such that the bag 14 may be connected to the storage case 18 in substantially the same manner as described above, except where one or more of the connection recesses 54 in the cover 118 does not receive a projection 46. Additionally or alternatively, in some embodiments multiple soft-sided bags 14 having smaller dimensions than the storage case 18 may be simultaneously connected to the storage case 18.

As shown in FIG. 11, a plurality of bins 170A, 170B, or inserts, are positioned within the base 114. The base 114 includes a bottom wall 172 and sidewalls 174 extending from the bottom wall defining an interior 176 with a depth D. The bins 170A, 170B are independently removable from the storage case 18 when the storage case 18 is open (i.e., the cover 118 is in the open position), as shown in FIG. 11. The bins 170A, 170B include relatively tall, or deep, bins 170A (FIG. 18) and relatively short, or shallow, bins 170B (FIGS. 12-17). The illustrated bins 170A, 170B are generally composed of plastic, but may alternatively be made of other materials. Each of the illustrated bins 170A, 170B is generally square in shape when viewed from above (FIG. 13). In other embodiments, the bins 170A, 170B may have other shapes (e.g., triangular, octagonal, circular, etc.). In the illustrated embodiment, the bins 170A, 170B are arranged within the base 114 as a grid of six (i.e., three rows of two). In other embodiments, the base 114 may be shaped and sized to receive a larger or smaller number of bins, and/or the bins 170A, 170B may be arranged within the base 114 in other patterns.

FIGS. 12-16 illustrate one of the relatively short bins 170B in detail. The bin 170B includes a bottom wall 186 and four sidewalls 190 extending generally perpendicularly from the bottom wall 186. The bottom wall 186 and the sidewalls 190 define a storage recess or space 194. Each of the relatively short bins 170B has a height HB (FIG. 14).

The bin 170B also includes ledges 198 formed on an inner surface 202 of the bin 170B at each corner 206 between adjacent sidewalls 190. The ledges 198 are positioned at a depth below a top edge 210 of the sidewalls 190 and a height above the bottom wall 186. In the illustrated embodiment, the ledges 198 are located at a depth that is approximately a quarter of the height HB below the top edge 210. In some embodiments the ledge 198 may extend around the perimeter of the sidewalls 190. The ledges 198 are configured to engage and support another bin when, for example, two relatively short bins 170B are stacked together, as best shown in FIG. 17. The bottom wall 186 at each corner 206 of the upper bin 170B is supported on each ledge 198 of the lower bin 170B. Each of the sidewalls 190 includes a lower, first portion 218 and an upper, second portion 222 that are stepped such that the first portion 218 has a smaller outer dimension than the second portion 222. As such, the sidewalls 190 of the upper bin 170B are partially received in the storage space 194 of the lower bin 170B up to the ledges 198 of the lower bin 170B. When stacked, the two relatively short bins 170B have a stacked height SH (FIG. 17). In other embodiments, more than two bins 170B may be stacked. Due to the top bin 170B being partially received in the bottom bin 170B, the stacked height SH is less than the total height of the two bins 170B (i.e., two times the height HB of the bins 170B).

The bin 170B further includes ribs 230 formed on an outer surface 234 of the bin 170B at the corners 206 between adjacent sidewalls 190. Each of the ribs 230 protrudes outwardly from the outer surface 234 and extends down from the top edge 210 toward the bottom wall 186. In the illustrated embodiment, each of the corners 206 has two ribs 230. In some embodiments, ribs may be formed on the sidewalls 190 between the corners 206 in addition to or in place of the ribs 230 formed at the corners 206.

As best shown in FIG. 19, when two or more bins 170B are stacked, the ribs 230 protrude from the outer surface 234 of the upper bin 170B to contact and engage the inner surface 202 of the lower bin 170B to space apart the sidewalls 190 of the stacked bins 170B. Accordingly, the ribs 230 help maintain a space or gap 238 between the stacked bins 170B for airflow, thereby inhibiting the stacked bins 170B from getting stuck together due to vacuum effects. In other words, the gap 238 provides fluid communication between a cavity formed between the inner surface 202 of the lower bin 170B and the outer surface 234 of the bin 170B below the ledge 198 of the lower bin 170B and atmosphere, thereby inhibiting a vacuum from forming when the bins 170B are stacked.

In some embodiments, such as the illustrated embodiment, the bin 170B includes a track 242 formed on the inner surface 202 of the bin 170B, as best shown in FIG. 16. The track 242 extends partially along two opposing sidewalls 190 and along the bottom wall 186. The track 242 is configured to removably receive a dividing wall 246, or partition, for dividing the storage space 194 into separate compartments. The illustrated dividing wall 246 splits the storage space 194 in half. In other embodiments, the track 242 and the dividing wall 246 may be positioned to split the storage space 194 into unequally sized compartments, or the bin 170B may include multiple tracks for receiving multiple dividing walls. In some embodiments, the track 242 and the dividing wall 246 may be omitted. In the illustrated embodiment, the height of the dividing wall 246 inhibits a bin 170B from being stacked on a bin 170B with a dividing wall 246. In other embodiments, the dividing wall 246 may have a height that does not interfere with stacking the bins 170B.

FIG. 18 illustrates one of the relatively tall bins 170A. The relatively tall bin 170A is substantially similar to the relatively short bins 170B. However, the relatively tall bin 170A has a height HA greater than the height HB of the relatively short bin 170B. The stacked height SH of two relatively short bins 170B, when stacked together, is generally equal to the height HA of the relatively tall bin 170A. In addition, the height HB of the one relatively tall bin 170A and the stacked height SH of two relatively short bins 170B stacked together are each generally equal to the height or depth D of the base 114 of the storage device 18.

As best shown in FIG. 20, a user may remove an upper bin of two stacked relatively short bins 170B within the base 114 of the storage case 18 to allow access to the storage space 194 of the lower bin 170B. Accordingly, the stacked bins 170B within the storage device 18 provide additional storage and organizing space that can be easily reconfigured and arranged as necessary.

Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects of the invention as described.

One or more independent features and/or independent advantages of the invention may be set forth in the claims.
