It is to be understood that the locations of protruding members 64 and 66 as shown in FIGS. 1, 2 and 15 are just examples and that protruding members 64 and 66 can be located at other locations. Furthermore, the actual number of protruding members 64 and 66 can be increased to accommodate more shelf members 26 or to provide more optional shelf positions.
Referring to FIGS. 1, 2 and 17-23, each shelf member 26 has top side 70, bottom side 72, and pair of opposing lengthwise end portions 74 and 76. Lengthwise end portion 74 has a plurality of slots 78 formed therein. Similarly, lengthwise end portion 76 has a plurality of slots 79 formed therein. Each of slots 78 and 79 is sized for receiving a portion of a corresponding divider member 28 in the same manner in which divider members 28 are inserted into slots 46 and 47 of bottom panel 16. Each shelf member 26 has longitudinally extending axis 80. Slots 78 and 79 are generally perpendicular to longitudinally extending axis 80. In one embodiment, slots 78 and 79 are equidistantly spaced. In another embodiment, slots 78 and 79 are not equidistantly spaced. In accordance with the invention, each lengthwise end portion 74 and 76 is generally triangular shaped. Lengthwise end portion 74 has first portion 82 that is angulated with respect to top side 70, and second portion 84 that is angulated with respect to first portion 82 and generally perpendicular to top and bottom sides 70 and 72, respectively. Slots 78 are formed in portion 82. Similarly, lengthwise end portion 76 has first portion 86 that is angulated with respect to top side 70, and second portion 88 that is angulated with respect to first portion 86 and generally perpendicular to top and bottom sides 70 and 72, respectively. Slots 79 are formed in portion 86. Thus, lengthwise end portions 74 and 76 have substantially the same structure. Each slot 78 is substantially coplanar with a corresponding slot 79. In one embodiment, portion 82 is angulated with respect to top side 70 by about 135°, and portion 86 is also angulated with respect to side 70 by about 135°. This is illustrated in FIGS. 22 and 23 which are enlarged views of the portions of the view of FIG. 18 indicated by reference numerals 90 and 92, respectively. However, it is to be understood that other degrees of angulation are possible. When storage unit 10 is completely assembled as shown in FIG. 1, front portions 84 of shelf members 26 are substantially coplanar.
Referring to FIGS. 17, 17A and 18-21, each shelf member 26 comprises a first plurality of pairs 100 of protruding members 100a and 100b that extend downward from bottom side 72 and are located near lengthwise end portion 76 (see FIG. 17A). This is also illustrated in FIG. 20 which is an enlarged view of the portion of the view shown in FIG. 18 indicated by reference numeral 103. Shelf member 26 further comprises a second plurality of pairs 102 of protruding members 102a and 102b that extend downward from bottom side 72 and are located near lengthwise end portion 74 (see FIG. 17A). This is also illustrated in FIG. 21 which is an enlarged view of the portion of the view shown in FIG. 19 that is indicated by reference numeral 108. Protruding member 100a is substantially aligned with protruding member 102a. Similarly, protruding member 100b is substantially aligned with protruding member 102b. Each pair 100 of protruding members 100a and 100b corresponds to a particular pair 102 of protruding members 102a and 102b so as to define a set of pairs of protruding members. For example, pair 100 of protruding members 100a and 100b and pair 102 of protruding members 102a and 102b define set 105 of protruding members. In order to facilitate understanding of the invention, the ensuing description makes reference to reference axes 104. Specifically, reference axes 104 are used to aid in the explanation of the structure of portions of each shelf member 26 and the placement of divider members 28 with respect to shelf members 26. Axes 104 extend laterally and are substantially perpendicular to longitudinally extending axis 80. In one embodiment, protruding members 100a and 100b are arranged in a staggered formation with respect to axis 104 (see FIG. 17A) and protruding members 102a and 102b are arranged in a staggered formation with respect to axis 104. Referring to FIG. 17B, there is shown an alternate embodiment of shelf member 26. Alternate shelf member 26′ has lengthwise end portions 74′ and 76′ that have substantially the same configuration as lengthwise end portions 74 and 76, respectively. Lengthwise end portions 74′ and 76′ have slots 78′ and 79′, respectively. The slots 78′ and 79′ function in the same manner as slots 78 and 79, respectively. Shelf member 26′ is configured so that the protruding members which extend from the bottom side (not shown) thereof are formed by a stamping process that is applied to the top surface 70′. As a result, corresponding indentations 111 are formed in top surface 70′ which result in the protrusions (not shown) being formed on and extending downward from the bottom side (not shown) of shelf member 26′. The configuration of shelf member 26′ is suitable when metal is the material from which shelf member 26′ is fabricated.
Referring to FIGS. 17, 17A and 18-21, each axis 104 corresponds to a single set of pairs of protruding members 100 and 102 (e.g. set 105). Each axis 104 is substantially coplanar with a corresponding slot 78 and a corresponding slot 79. The protruding members of each pair in set 105 are offset in opposite directions with respect to the corresponding axis 104 such that one protruding member of each pair 100 and 102 is located on one side of the axis 104 and the other protruding member of each pair 100 and 102 is located on the other side of axis 104. For example, protruding members 100a and 100b are offset in opposite directions such that protruding member 100a is located on one side of axis 104a and protruding member 100b is located on the other side of axis 104a. Similarly, protruding members 102a and 102b are offset in opposite directions such that protruding member 102a is located on one side of axis 104a and protruding member 102b is located on the other side of axis 104a. 
In an alternate embodiment, protruding members 100a and 100b are not arranged in a staggered formation with respect to axis 104 but instead, are positioned so that they are substantially aligned with each other and are the same distance from longitudinally extending axis 80. Similarly, in an alternate embodiment, protruding members 102a and 102b are not arranged in a staggered formation with respect to axis 104 but instead, are positioned so that they are substantially aligned with each other and are the same distance from longitudinally extending axis 80. These alternate embodiments are shown in FIGS. 47A, 47B and 47C. Alternate shelf member 400 has a top side 402, a bottom side 404 and lengthwise end portions 406 and 408. Lengthwise end portions 406 and 408 have generally the same configuration as lengthwise end portions 74 and 76, respectively. Lengthwise end portions 406 and 408 have slots 409 that function in the same manner as slots 78 and 79 described in the foregoing description. Protrusions 410 extend downward from bottom side 404 and are formed by a stamping process that is applied to top side 402. Protrusions 410 are also shown in FIG. 47C which is an enlarged view of the portion of the view of FIG. 47B indicated by reference numeral 411. In this embodiment, protrusions 410 are arranged in pairs wherein the protrusions of each pair are substantially aligned with each other and are not staggered. Furthermore, there are three pairs of protrusions 410 that are substantially aligned with a corresponding pair of slots 409A and 409B in lengthwise end portions 404 and 406, respectively. The aforementioned stamping process creates indentations 412 in top side 402.
Referring to FIGS. 2-5, 17 and 17A, when storage unit 10 is completely assembled, each slot 38 in rail member 36 is substantially coplanar with a corresponding slot 78 in lengthwise end portion 74 of uppermost shelf member 26a and a corresponding slot 79 in lengthwise end portion 76 of uppermost shelf member 26a. Each laterally extending axis 104 of a particular shelf member 26 (see FIG. 17A) is substantially coplanar with corresponding slots in lengthwise end portions 74 and 76 of a shelf member 26 that is located directly beneath the aforementioned particular shelf member 26. For example, each laterally extending axis 104 of shelf member 26a is substantially coplanar with a corresponding slot 78 and a corresponding slot 79 of shelf member 26c. Similarly, each laterally extending axis 104 of shelf member 26b is substantially coplanar with a corresponding slot 46 and a corresponding slot 47 of bottom panel 16.
Referring to FIGS. 1, 2, and 14, when each divider member 28 is positioned on shelf member 26b, which is below shelf member 26d, divider member 28 contacts bottom side 72 of shelf member 26d and is positioned along a corresponding laterally extending axis 104 of bottom side 72 of shelf member 26d such that protruding member 100a (of shelf member 26d) is located on one side of divider member 28 and protruding member 100b (of shelf member 26d) is located on the other side of divider member 28, and portions of divider member 28 are inserted into slots 78 and 79 of shelf member 26b that are substantially coplanar with the laterally extending axis 104 of shelf member 26d along which the divider member 28 is positioned. The manner in each which divider member 28 is positioned between shelf members 26 is described in detail in the ensuing description.
Similarly, when each divider member 28 is positioned between bottom panel 16 and lowermost shelf member 26b, divider member 28 contacts bottom side 72 of shelf member 26b and is positioned along a corresponding laterally extending axis 104 of shelf member 26b such that protruding members 100a and 102a (of shelf member 26b) are located on one side of divider member 28 and protruding members 100b and 102b (of shelf member 26b) are located on the other side of divider member 28, and portions of divider member 28 are inserted into corresponding slots 46 and 47 (of bottom panel 16) that are substantially coplanar with the laterally extending axis 104 (of shelf member 26b) along which the divider member 28 is positioned.
Referring to FIGS. 1, 2, and 24-34, there is shown divider member 28. Each divider member 28 comprises base member 110 and top member 112 that is removably mounted to base member 110. In a preferred embodiment, top member 112 has a generally planar shape. Base member 110 comprises a lower portion 114 that has distal ends 116 and 118. Distal end 118 has a notch 120. Referring to FIG. 34, distal ends 116 and 118 are sized to be removably inserted into corresponding slots 78 and 79, respectively, of shelf member 26. In a preferred embodiment, distal end 118 is tapered to facilitate insertion into a corresponding slot 79. In order to removably mount a divider member 28 on a shelf member 26, a user first mounts only base member 110 on shelf member 26 by first inserting distal end 118 into a slot 79 of lengthwise end portion 76 and then lowering base member 110 so that distal end 116 is inserted into a corresponding slot 78 (in lengthwise end portion 74) that is coplanar with the aforementioned slot 79 in lengthwise end portion 76.
Referring to FIGS. 1, 2, and 24-34, base member 110 further comprises upper portion 130 that comprises a first plurality of upwardly protruding spaced members 132 positioned along first axis 134 and a second plurality of upwardly protruding spaced members 136 positioned along second axis 138. First and second axes 134 and 138, respectively, are substantially parallel to and offset from each other thereby defining longitudinally extending channel 139. Top member 112 is removably mounted to upper portion 130. Specifically, top member 112 is inserted into longitudinally extending channel 139. Top member 112 includes flanged end portion 140 that contacts upwardly protruding member 132a when top member 112 is completely inserted into longitudinally extending channel 139. The height of each upwardly protruding, spaced member 132 and 136 can be varied depending upon the size of top member 112. Furthermore, the distance in which the first and second plurality of upwardly protruding spaced members 132 and 136, respectively, are offset from one another can be varied so as to vary the size of longitudinally extending channel 139 so as to accommodate top members 112 of different sizes.
Referring to FIGS. 1, 2 and 24-34, upper portion 130 of base member 110 further comprises resilient members 150, 152 and 154 that have a compressed state and a normal, uncompressed state. Resilient members 150, 152 and 154 are positioned along channel 139. Resilient members 150, 152 and 154 comprise upwardly extending flange portions 160, 162 and 164, respectively. The normal uncompressed state of resilient members 150, 152 and 154 is illustrated in FIGS. 24, 25, 26, 29 and 30. The compressed state of resilient members 150, 152 and 154 is shown in FIGS. 32 and 33. The main purpose of resilient members 150, 152 and 154 is to allow a user to easily insert top member 112 into longitudinally extending channel 139 when base member 110 is already mounted on a shelf member 26 or bottom panel 16 and to allow the completely assembled divider members 28 to be snugly positioned between (i) shelf members 26, (ii) top panel 14 and uppermost shelf member 26a, and (iii) bottom panel 16 and lowermost shelf member 26b (see FIG. 1). Once top member 112 is completely inserted into channel 139, resilient members 150, 152 and 154 create a slight upward force that pushes top member 112 upward so as to cause top member 112 to completely contact the bottom side of the shelf member or top panel member that is above the top member 112. Flange portions 160, 162 and 164 abut top member 112 when top member 112 is inserted into longitudinally extending channel 139. Specifically, resilient members 150, 152 and 154 compensate for non-uniformity in the height between shelf members 26 or between top panel 14 and uppermost shelf member 26a or between lowermost shelf member 26b and bottom panel 16 by allowing the height H (see FIG. 30) of each divider member 28 to be varied. Thus, the degree of compression of resilient members 150, 152 and 154, when the divider members 28 are positioned in storage unit 10, may vary depending upon the actual height between shelf members 26 or between top panel 14 and uppermost shelf member 26a, or between lowermost shelf member 26b and bottom panel 16. The thickness, length and shape of resilient members 150, 152 and 154 can be varied in order to achieve the desired tension.
Referring to FIGS. 1-5, 32, 33 and 34, when each divider member 28 is removably mounted on a shelf member 26, end 118 of base member 110 is inserted into a corresponding slot 79 and end 116 is inserted into a corresponding slot 78 that is substantially coplanar with the aforementioned slot 79. When base member 110 is mounted to shelf member 26, longitudinally extending channel 139 is substantially aligned with a corresponding laterally extending axis 104 of the shelf member 26 that is positioned above the divider member 28. Top member 112 is then inserted into the longitudinally extending channel 139 of base member 110. As top member 112 is being slid into longitudinally extending channel 139, top edge portion 113 of top member 112 is substantially aligned with a corresponding axis 104 of the shelf member 26 that is above the divider member 28. As top member 112 slides into the interior of storage unit 10, top edge portion 113 slides between protruding members 102a and 102b, and between protruding members 100a and 100b. When top member 112 is completely inserted into longitudinally extending channel 139, flanged edge portion 140 abuts protruding member 132a, and resilient members 150, 152, and 154 are compressed to a degree that depends upon the actual height between that particular shelf member 26 and the shelf member 26 directly above the aforementioned particular shelf member. The resilient members 150, 152 and 154 ensure that the top edge portion 113 of top member 112 firmly abuts bottom side 72 of the upper shelf member 26 and that top edge 113 stays between protruding members 100a and 100b and between protruding members 102a and 102b. Divider members 28 are positioned between bottom panel 16 and lowermost shelf member 26b in the same manner as described in the foregoing description. When divider members 28 are to be positioned between uppermost shelf member 26a and top panel 14, base member 110 is mounted to shelf member 26a in the same manner as described above. However, when top member 112 is inserted into longitudinally extending channel 139, top edge portion 113 of top member 112 is inserted into a corresponding one of slots 38 of rail member 36 (see FIGS. 3-5) that is substantially coplanar with the longitudinally extending channel 139. Resilient members 150, 152 and 154 function in the same manner as described above and cause top member 112 to be snugly positioned within a corresponding slot 38 of rail member 36. FIG. 14 shows a plurality of divider members 28 equidistantly positioned within storage unit 10 to provide a plurality of openings or compartments 30 having the same size. It is to be understood that divider members 28 can be positioned so as to provide a plurality of openings or compartments 30 that have different sizes. Such a configuration provides a user with the option of utilizing drawers of different sizes in the spaces or compartments 30. This is illustrated in FIG. 14.
Divider member 28 can be fabricated from a variety of materials, e.g. plastic, rubber, metal, etc. Furthermore, top member 112 can be fabricated from metal, wood, plastic, rubber, etc.

Drawer support member 174 includes cut-out or notch 180 that is adjacent distal end portion 178. Cut-outs 176 form relatively narrow portion 181 of top surface portion 175. As shown in FIG. 37, drawer 172 includes bottom side 184 and a pair of opposing extending engagement members 186 and 188. In a preferred embodiment, drawer 172 includes parallel tracks 189 that extend from engagement members 186 and 188 along the bottom side 184 of drawer 172. Narrow portion 181 of drawer support member 174 is sized to fit between, but not under, engagement members 186 and 188. In order to movably mount drawer 172 on drawer support member 174, narrow portion 181 is first positioned between engagement members 186 and 188. Next, drawer 172 is moved with respect to drawer support member 174 so that the wider portion of top surface portion 175 slides between tracks 189 and under engagement members 186 and 188, as shown in FIG. 36. Once the wider portion of top surface portion 175 is slidably positioned under engagement members 186 and 188, drawer 172 can slide upon top surface portion 175 and extend out of storage unit 10 without tipping or falling out of storage unit 10. In order to disengage drawer 172 from drawer support member 174, drawer 172 is moved relative to drawer support member 174 so that relatively narrow portion 181 becomes aligned with engagement members 186 and 188. Once relatively narrow portion 181 becomes aligned with engagement members 186 and 188, drawer 172 can be dismounted from drawer support member 174.
In order to mount drawer assembly 170 to bottom panel 16, the user first grasps drawer assembly 170 and inserts end portion 178 into a predetermined slot 46 in lengthwise end portion 42 in such a manner that notch 180 engages the perimetrical edge of the slot 46.
