DETAILED DESCRIPTION OF THE INVENTION [141] Referring to Fig. 1, a shelving system 10 in accordance with one embodiment of the present invention comprises four substantially vertical corner columns 100, 101 , 102, 103 and a plurality of substantially horizontal support beams 104 extending between the corner columns 100, 101 , 102, 103. The support beams 104 are preferably arranged in pairs and can be used to support horizontally-oriented shelves 106. For example, Fig. 56 shows a version of the shelving system 10 with shelves 106 that are wire shelves. However, it is understood that other types of shelves (e.g. planar shelves) are also possible. Support beams 104 may extend between corner columns 100 and 102, and between corner columns 101 and 103. The support beams 104 in each pair of support beams 104 are preferably at the same height, although this is not necessarily required. [142] The corner columns 100, 101, 102, 103 are also preferably arranged in pairs, with corner columns 100 and 101 forming one pair, and corner columns 102 and 103 forming another pair. One or more substantially horizontal side braces 108 may extend between the corner columns 100 and 101, and between the corner columns 102 and 103. Furthermore, one or more inclined braces 1 10 may extend between the corner columns 100 and 101, and between the corner columns 102 and 103. The inclined braces 1 10 preferably extend at a angle (with respect to the substantially horizontal side braces 108).

[143] The support beams 104 comprise an elongated member 218 that is preferably formed by bending a single sheet of material, such as metal. Referring to Figs. 2 and 3, the elongated member 218 extend along a generally longitudinal direction. Each of the elongated member 218 comprises an outer face 112 extending between upper and lower horizontal faces 114, 1 16. An inward face 118 extends from the upper horizontal face 1 14, and a shelf support ledge 120 extends from the inward face 1 18. The support beams 104 in each pair of support beams 104 are preferably arranged such that the outer faces 1 12 of the support beams 104 are on an exterior of the shelving system 10. In other words, the shelf support ledges 120 for the support beams 104 for each pair of support beams 104 preferably extend inwardly towards an interior of the shelving system 10.

[144] Shelf 106 is preferably supported by the shelf support ledges 120 of the support beams 104 in each pair of support beams 104. The presence of the inward faces 118 limits any lateral movement of the shelves 106.

[145] The support beams 104 further comprise generally angled end connectors 122 on opposing ends of the elongated member 218. The end connectors 122 are configured to attach to the corner columns 100, 101 , 102, 103, as described later. The end connectors 122 may be connected to the elongated member 218 by welding or some other connection means.

[146] A number of beam braces 124 preferably extend between support beams 104. The beam braces 124 comprise first and second brace ends 172, 174 and preferably extend between the support beams 104 of a pair of support beams 104, such that the beam braces 124 extend substantially horizontally. The beam braces 124 are preferably made by bending a single sheet of material, such as metal. Referring to Figs. 4 to 8, the beam braces 124 have a generally Z-shaped cross-section comprising a middle portion 126 extending between first and second portions 128, 130. The first portion 128 and the second portion 130 extend in generally opposite directions away from the middle portion 126, thus forming the generally Z-shaped cross-section.

[147] The first portion 128 preferably comprises a generally planar first surface 132 with downward-facing tabs 134 extending from opposing ends of the first surface 132. The tabs 132 are sized and configured to fit into slot openings 136 formed on the support beams 104. The slot openings 136 are preferably formed on the shelf support ledge 120, proximate to its juncture with the inward face 118, as shown in Fig. 2.

[148] The second portion 130 preferably comprises a generally planar second surface 138 with a generally round brace opening 140 formed thereon proximate to the first brace end 172. The brace opening 140 generally correspond with one of the beam openings 142 formed on the lower horizontal face 116. The brace openings 140 of the beam braces 124 and the beam openings 142 are generally sized and configured to engage with brace fasteners 144 for securing the beam braces 124 to the support beams 104, as shown in Fig. 4. The brace fasteners 144 may be any suitable type of mechanical fasteners, such as nut-and-bolt fasteners, threaded fasteners, rivets, pins, etc. The number of slot openings 136 and the beam openings 142 on the support beam 104 preferably correspond to the number of beam braces 124 intended to extend from the support beam 104. For example, in the embodiment shown in Fig. 1, four beam braces 124 extend between each pair of support beams 104. Accordingly, each of the support beams 104 preferably comprises four slot openings 136 and four beam openings 142.

[149] The second portion 130 also preferably comprises a knob 176 extending from the lower portion of the second surface 138. The knob 176 is preferably sized such that it is able engage within one of the brace openings 140.

[150] When the beam brace 124 is attached to the support beam 104, the first surface 132 and the second surface 138 are substantially horizontal and parallel to each other. As shown in Fig. 7, the second surface 138 is preferably slightly longer in length than the first surface 132.

[151] In the embodiment shown in Figs. 5 to 8, the middle portion 126 comprises a substantially planar vertical surface 146 with first and second edges 148, 150. The vertical surface 146 is substantially perpendicular to both the first surface 132 and the second surface 138. The vertical surface 146 preferably comprises notches 152 cut out from opposing ends of the vertical surface 146, proximate to the first edge 148. The presence of the notches 152 allows the opposing ends of the vertical surface 146 to fit under the shelf support ledge 120 when the beam brace 124 extends between the support beams 104, as shown in Fig. 4.

[152] Because of the substantial verticality of the vertical surface 146, the first surface 132 and the second surface 138 are offset from each other, as shown in Fig. 8. In other words, the first surface 132 and the second surface 138 are both fully visible when the beam brace 124 is viewed directly from above (e.g. Fig. 7) or below. [153] The first portion 128 extends from the first edge 148, and the second portion 130 extends from the second edge 150. As shown in Fig. 7, the length of the second edge 150 is preferably substantially similar to the length of the second surface 138. However, because of the presence of the notches 152, the length of the first edge 148 is less than the length of the first surface 132. Preferably, the length of the first surface 132 is somewhere between the lengths of the first edge 148 and the second edge 150.

[154] Figs. 9 to 14 show alternate embodiments for the middle portion 126 of the beam brace 124. Referring to Figs. 9 and 10, in this embodiment, the middle portion 126a of the beam brace 124a comprises vertical surface 146a and upper and lower inclined surfaces 154, 156. The vertical surface 146a extends between the upper inclined surface 154 and the lower inclined surface 156. In addition, an upper surface 158 may extend between the upper inclined surface 154 and the first surface 132, and a lower surface 160 may extend between the lower inclined surface 156 and the second surface 138. Preferably, the upper surface 158 and the lower surface 160 are substantially vertical; however, this is not always the case. In the embodiment shown in Figs. 9 and 10, the upper inclined surface 154 and the lower inclined surface 156 are substantially parallel to each other; however, this is also not always the case. Notches 152 may only extend in the upper inclined surface 154 and the upper surface 158 (as shown in Fig. 9). Alternatively, the notches 152 may extend into the vertical surface 146a as well.

[155] As shown in Fig. 10, the first surface 132 and the second surface 138 are now partially offset from each other, because of the presence of the upper and lower inclined surfaces 154, 156. In other words, the first surface 132 and the second surface 138 overlap one another when the beam brace 124a is viewed directly from above or below.

[156] Figs. 1 1 and 12 show another alternate embodiment for the middle portion 126b of the beam brace 124b. In this configuration, the middle portion 126b comprises an inclined surface 162b extending between the first surface 132 and the second surface 138. The inclined surface 162b is angled such that the first surface 132 and the second surface 138 are partially offset from each other. In other words, the first surface 132 and the second surface 138 overlap one another when the beam brace 124b is viewed directly from above or below. Notches 152 are formed on opposing ends of the inclined surface 162b, proximate to the first edge 148.

[157] Figs. 13 and 14 show yet another alternate embodiment for the middle portion 126c of the beam brace 124c. In this configuration, the middle portion 126c also comprises inclined surface 162c; however, in this configuration, the inclined surface 162c is at such an angle that the first surface 132 and the second surface 138 are substantially aligned. In other words, the first surface 132 and the second surface 138 lie substantially on top of one another when the beam brace 124c is viewed directly from above or below.

[158] Figs. 15 to 19 show a partial view of the shelving system 10 showing support beam 104 with associated beam brace 124. The support beam 104 and the beam brace 124 may be in a closed configuration (as shown in Figs. 17 and 18) or in an open configuration (as shown in Figs. 15 and 16). The closed configuration may be appropriate when the shelving system 10 is in a disassembled form, while the open configuration is appropriate when the shelving system 10 is assembled (i.e. as depicted in Fig. 1).

[159] Referring to Figs. 15, 16, and 19, as described earlier, the beam brace 124 may be secured to the support beam 104 through the brace fastener 144. The brace fastener 144 may be a pin 164 that extends through one of the brace openings 140 and one of the beam openings 142. The pin 164 comprises an elongated portion 166 with opposing first and second pin ends 168, 170. Preferably, the elongated portion 166 has a diameter that is smaller than that of the brace opening 140 or the beam opening 142. In addition, preferably, the first and second pin ends 168, 170 have a diameter that is greater than that of the brace opening 140 or the beam opening 142. Accordingly, the pin 164 cannot be easily removed and ensures that the beam brace 124 is held securely to the support beam 104.

[160] Through the pin 164, the beam brace 124 is able to pivot from the closed

configuration to the open configuration, as described below. [161] Referring to Figs. 17 and 18, the beam brace 124 is shown in the closed configuration with respect to the support beam 104. The pin 164 extends through one of the beam openings 142 and through the brace opening 140 that is proximate to the first brace end 172. While pivoting to the open configuration, the downward-facing tabs 134 on the first brace end 172 will come into contact with the shelf support ledge 120 of the support beam 104. The first surface 132 proximate to the first brace end 172 may then be deformed slightly (e.g. lifted upward) from its substantially planar orientation in order to allow the tab 134 to slide across the surface of the shelf support ledge 120. As the beam brace 124 continues to pivot away from the support beam 104 (in direction A, as shown in Fig. 17), the tab 134 will eventually slide across the top of slop opening 136, at which point the tab 134 will engage into and fit within the slot opening 136. The engagement of the tab 134 within the slot opening 136 causes the first surface 132 to revert back to its substantially planar orientation, thus locking the beam brace 124 in place with respect to the support beam 104 and achieving the open configuration.

[162] In order to move the beam brace 124 from the open configuration back to the closed configuration, the tab 134 proximate to the first brace end 172 may be lifted out of the slot opening 136, resulting in a slight deformation to the first surface 132 proximate to the first brace end 172. Through the pin 164, the beam brace 124 can then be pivoted towards the support beam 104 (in direction B, as shown in Fig. 15). The tab 134 can then slide across the surface of the shelf support ledge 120 until it clears the surface, at which point the first surface 132 will revert back to its substantially planar orientation. The beam brace 124 can continue to pivot towards the support beam 104 until it is substantially collinear with the support beam 104, thus achieving the closed configuration.

[163] Referring to Figs. 20 and 21, when assembling the shelf system 100, two support beams 104 may be connected via two or more beam braces 124 to form part of one level of the shelf system 100. Figs. 20 and 21 depict two support beam 104, 104 ' connected with two beam braces 124, 124 '; however, it is understood that additional beam braces 124 may also be used. The beam braces 124, 124' are first placed in the open configuration (as described above) with their respective support beams 104, 104 ' . The tab 134 proximate to the second brace end 174 of beam brace 124 can be inserted into one of the slot openings 136 ' of the support beam 104 ' . Similarly, the tab 134' proximate to the second brace end 174 ' of beam brace 124' can be inserted into one of the slot openings 136 of the support beam 104.

[164] Preferably, the knob 176 of the beam brace 124 engages with one of the beam openings 142 ' on support beam 104', and the knob 176' of the beam brace 124' engages with one of the beam openings 142 on support beam 104. [1 5] In this manner, a rigid configuration comprising two support beam 104, 104' and at least two beam braces 124, 124' is formed. The end connectors 122, 122' can then be attached to the corner columns 100, 101, 102, 103 to continue the assembly of the shelf system 100.

[166] Figs. 22 to 27 show another embodiment for support beam 104d and its associated beam brace(s) 124d. Although Fig. 22 shows support beam 104d having only one associated beam brace 124d, it is understood that the support beam 104d may have multiple beam braces 124d.

[167] As with the previous embodiment, the support beam 104d and its associated beam brace(s) 124d may be in either a closed configuration (as shown in Figs. 24 and 25) or in an open configuration (as shown in Figs. 22 and 23). Similar to the previous embodiment, the support beam 104d comprises outer face 112 extending between upper and lower horizontal faces 1 14, 1 16, with inward face 1 18 extending from the upper horizontal face 1 14, and the shelf support ledge 120 extending from the inward face 1 18. Slot openings 136 are formed on the shelf support ledges 120. [168] Unlike the previous embodiment where beam openings 142 are present on the lower horizontal face 1 16 only, in this embodiment, beam openings 142d are preferably located on both the upper and lower horizontal faces 114, 116. Preferably, as shown in the embodiment in Figs. 22 to 27, the beam openings 142d are arranged such that each of the beam openings 142d on the upper horizontal face 1 14 is substantially in line with one beam opening 142d on the lower horizontal face 1 16. Additionally, each of the slot openings 136 on the upper horizontal face 1 14 is preferably substantially in line with one beam opening 142d on the lower horizontal face 1 16.

[169] Referring to Figs. 22 and 23, the beam braces 124d are pivotably connected to the support beam 104d, as with the previous embodiment. However, the manner of attachment of the beam brace 124d to the support beam 104d is different, as described below.

[170] As with the previous embodiment, the beam brace 124d has first and second brace ends 172, 174, with each beam brace 124 further comprising a middle portion 126 extending between first and second portions 128, 130. Referring to Fig. 27, first portion 128 comprises generally planar first surface 132, while second portion 130 comprises generally planar second surface 138. In this embodiment, the middle portion 126 is preferably inclined, such that the first surface 132 and the second surface 138 lie substantially on top of one another when the beam brace 124d is viewed directly from above or below (i.e. similar in

configuration to that of beam brace 124c). [171] Both the first portion 128 and the second portion 130 comprise brace openings 140d proximate to the first brace end 172. The first portion 128 also comprises downward-facing tab 134 extending from the first surface 132 proximate to the second brace end 174. As with the previous embodiment, the second portion 130 also preferably comprises knob 176 extending from the lower portion of the second surface 138. [172] The beam brace 124d is pivotably connected to the support beam 104d by means of brace fasteners 144d. Each beam brace 124d is preferably pivotably connected to the support beam 104d by two brace fasteners 144d, as shown in Fig. 24. One brace fastener 144d extends through the beam opening 142d on the upper horizontal face 1 14 and the brace opening 140 on the first portion 128. Another brace fastener 144d extends through the beam opening 142d on the lower horizontal face 116 and the brace opening 140 on the second portion 130.

[173] The brace fasteners 144d may be in the form of pins 164. Preferably, the elongated portion 166 of the pin 164 has a diameter that is smaller than that of the brace opening 140 or the beam opening 142d. In addition, preferably, the first and second pin ends 168, 170 have a diameter that is greater than that of the brace opening 140 or the beam opening 142d.

[174] Through brace fasteners 144d, the beam brace 124d is able to pivot from the closed configuration to the open configuration (and vice versa). While pivoting from the closed configuration to the open configuration, the beam brace 124d moves from being substantially collinear with the support beam 104d to be substantially perpendicular to the support beam 104d. For example, Fig. 26 shows the beam brace 124d in midst of the transition from the closed configuration to the open configuration.

[175] When two support beams 104d are to be attached together (e.g. via two beam braces 124d), tab 134 and knob 176 of a first beam brace 124d (already +connected to the first support beam 104d) may be used to engage slot opening 136 and beam opening 142d, respectively, of the second support beam 104d, as described for previous embodiments. Similarly, tab 134 and knob 176 of the second beam brace 124d (already connected to the second support beam 104d) may be used to engage slot opening 136 and beam opening 142d, respectively, of the first support beam 104d.

[176] Referring to Figs. 28 to 30, each of the corner columns 100, 101 , 102, 103 is preferably formed from a single sheet of material, such as metal, that is bent to form a substantially C-shaped cross-section.

[177] Figs. 28 to 30 show one embodiment of the corner columns 100, 101, 102, 103. In this embodiment, each of the corner columns 100, 101 , 102, 103 comprises opposed column walls 178, each with first and second column edges 180, 182. A central portion 184 extends between the opposed column walls 178 from the respective first column edges 180.

Preferably, column flanges 186 extend from the respective second column edges 182 of the opposed column walls 178. Each of the column flanges 186 is preferably substantially perpendicular to the column wall 178 from which it extends. Figs. 28 to 30 shows corner column 100, but it is understood that the other corner columns 101, 102, 103 are similar.

[178] As shown in Fig. 1, the corner columns 100, 101, 102, 103 are preferably arranged such that their respective central portions 184 are on the exterior of the shelving system 10. The central portions 184 also comprise a plurality of slots 188. The slots 188 are used when connecting the end connectors 122 of the support beams 104 to the corner columns 100, 101, 102, 103. Preferably, the slots 188 are generally angled (as shown in Figs. 28 to 30).

However, it is understood that other orientations (and shapes) are also possible (e.g. round, rectangular, etc.). [179] The arrangement of the opposed column walls 178, the central portion 184, and the column flanges 186 form a generally C-shaped cross-section (as shown in Figs. 28 to 30) that generally defines a channel 190. The channel 190 is shaped to engage with the side braces 108 and the inclined braces 1 10.

[180] The shape of the central portion 184 may be different in different embodiments. In one embodiment, as shown in Figs. 28 to 30, the central portion 184 is generally planar, with the central portion 184 being substantially perpendicular to the opposed column walls 178. In this embodiment, the slots 188 are preferably arranged in two columns that extend for at least a portion of the height of the central portion 184. The slots 188 may be further arranged such that the two slots 188 in each row are mirror images of each other, thus forming a generally V shape for each row. It is understood that other shapes and arrangements of the slots 188 may also be used.

[181] In order to attach the support beam 104 to one of the corner columns 100, 101, 102, 103, one of the end connectors 122 of the support beam 104 is utilized. Figs. 29 and 30 show one of the end connectors 122. The end connector 122 comprises first and second end plates 192, 194. The first and second end plates 192, 194 are preferably substantially perpendicular to each other.

[182] Referring to Figs. 2, 29 and 30, the first end plate 192 preferably comprises one or more end plate tabs 196. The end plate tabs 196 are protrusions that extend from an inner plate surface 198 of the first end plate 192. Preferably, the end plate tabs 196 are formed by cutting through the first end plate 192 and bending the cut portion towards the second end plate 194 such that it protrudes from the inner plate surface 198. However, other methods for forming the end plate tabs 196 are also possible. The position and size of the end plate tabs 196 are chosen so that they will fit within the slots 188 on the corner columns 100, 101, 102, 103, thereby allowing the attachment of the end connector 122 (and thus the support beam 104) to the corner columns 100, 101, 102, 103. [183] The first end plate 192 also preferably comprises one or more pin openings 200. The pin openings 200 allow a beam pin 202 to be inserted through the first end plate 192 and one of the slots 188. The beam pin 202 has a generally tubular shape with a bend in it. The beam pin 202 acts to further secure the end connector 122 to the corner columns 100, 101, 102, 103 and prevents the unintended detachment of the end connector 122 from the corner columns 100, 101, 102, 103.

[184] Other shapes for the central portion 184 are also possible. In another embodiment of the corner columns lOOe, lOle, 102e, 103e, the central portion 184e is not substantially planar (as in the previous embodiment) but is instead indented (i.e. towards the interior of the shelving system 10). Figs. 31 to 34 show this embodiment. In this embodiment, the central portion 184e comprises first and second angled surfaces 204, 206, with each of the first and second angled surfaces 204, 206 forming acute angles C, D with their respective column wall 178. Preferably, the acute angles C, D are identical to each other, but this is not necessarily required. The acute angles C, D are preferably at least approximately 12 degrees from perpendicular (i.e. approximately 78 degrees or less); however, other angles are also possible.

[185] The slots 188 may also still be arranged in two columns, with one column of slots 188 on the first angled surface 204 and a second column of slots on the second angled surface 206.

[186] Referring to Fig. 35 to 37, in this embodiment, the end connectors 122e are preferably adapted to take into account the indentation in the central portion 184e. Accordingly, the first and second end plates 192e, 194e are preferably angled to each other at an angle that is substantially identical to the angle between the first or second angled surfaces 204, 206 and their respective column wall 178.

[187] Fig. 33 shows the end connector 122e attached to corner column lOOe. The first end plate 192e comes into contact with the first angled surface 204, and the second end plate 194e comes into contact with the column wall 178. Therefore, the angle C between the first end plate 192e and the second end plate 194e preferably corresponds to the angle C between the first angled surface 204 and the column wall 178 to allow the end connector 122e to fit snugly against the corner column lOOe. Although only corner column lOOe is shown, it is understood that the other corner columns lOle, 102e, 103e are similar. However, for corner columns lOle, 102e, due to their orientation, the end connectors 122e would come into contact with the second angled surfaces 206 instead.

[188] Figs. 38 to 41 show another embodiment for the corner columns lOOf, lOlf, 102f, 103f. In this embodiment, the first and second angled surfaces 204f, 206f of the central portion 184f are not indented, but instead protrude outwards. In this embodiment, the first and second angled surfaces 204f, 206f each form obtuse angles E, F with their respective column wall 178. Preferably, the obtuse angles E, F are identical to each other, but this is not necessarily required. The obtuse angles E, F should be at least approximately 12 degrees from perpendicular (i.e. approximately 102 degrees or greater). More particularly, the obtuse angles E, F are preferably approximately 1 15 degrees or greater.

[189] Referring to Figs. 42 to 44, in this embodiment, the end connectors 122f are again preferably adapted to take into account the protrusion in the central portion 184f. Accordingly, the first and second end plates 192f, 194f are preferably angled to each other at an angle that is substantially identical to the angle between the first or second angled surfaces 204f, 206f and their respective column wall 178.

[190] Fig. 40 shows the end connector 122f attached to corner column lOOf. The first end plate 192f comes into contact with the first angled surface 204f, and the second end plate 194f comes into contact with the column wall 178. Therefore, the angle E ' between the first end plate 192f and the second end plate 194f preferably corresponds to the angle E between the first angled surface 204f and the column wall 178 to allow the end connector 122f to fit snugly against the corner column lOOf. Although only corner column lOOf is shown, it is understood that the other corner columns lOlf, 102f, 103f are similar. However, for corner columns lOlf, 102f, due to their orientation, the end connectors 122f would come into contact with the second angled surfaces 206f instead. [191] In the above embodiments where the central portion 184 is not planar, the angling of the central portion 184 increases the overall strength of the corner columns 100, 101, 102, 103. In addition, by angling the central portion 184 with respect to the column walls 178, any end connectors 122 that will be used to attach the support beams 110 to the corner columns 100, 101, 102, 103 will preferably have a similar angle as well. This prevents non-compatible parts from other shelving systems from being used with the present shelving system 10. In particular, when the angle between the first or second angled surfaces 204, 206 and its respective column wall 178 is at least approximately 12 degrees from perpendicular, this will prevent end connectors 122 from non-compatible shelving systems (e.g. end connectors with perpendicular first and second end plates) from being attached to the corner column 100, 101, 102, 103.

[192] Figs. 45 to 50 show a further embodiment for the corner columns l OOg, lOlg, 102g, 103g. In this embodiment, the corner columns l OOg, lOlg, 102g, 103g do not have opposed column walls 178 as in the previous embodiments. Instead, the corner columns lOOg, 10 lg, 102g, 103g comprise first and second angled column walls 208, 210. The first and second angled column walls 208, 210 preferably extend from a central wall 212; however, it is also possible for the central wall 212 to be omitted, such that the first and second angled column walls 208, 210 lie adjacent to one another. Column flanges 186 may also extend from an outer edge 214 of each of the first and second angled column walls 208, 210. Although only corner column lOOg is shown in Fig. 47, it is understood that the other corner columns lOlg, 102g, 103 g are preferably similar.

[193] Referring to Fig. 50, the first and second angled corner walls 208, 210 are angled with respect to the column flanges 186 at an angle G, G ' . Preferably, the angles G, G ' are identical to each other and are acute angles (when viewed from above). Preferably, the angles G, G ' are approximately 45 degrees, although other angles are also possible. [1 4] As best shown in Figs. 45 and 46, the corner columns lOOg, lOlg, 102g, 103g are arranged such that their first and second angled column walls 208, 210 and the central wall 212 (if any) face the exterior of the shelving system lOg. Referring to Fig. 47, the first and second angled column walls 208, 210 preferably comprise a plurality of slots 188.

[195] In the embodiment shown in Figs. 45 to 50, the slots 188 are arranged in two columns that extend for at least a portion of the corner columns lOOg, lOlg, 102g, 103g, with one column of slots 188 on the first angled column wall 208 and a second column of slots 188 on the second angled column wall 210.

[196] Referring to Figs. 51 to 53, in this embodiment, the end connector 122g is adapted to couple with either the first angled column wall 208 or the second angled column wall 210. Figs. 47 and 48 show the support beam 104g attached to corner column lOOg. It is understood that the attachment of the support beam 104g to other corner columns lOlg, 102g, 103g is similar. In this embodiment, the end connector 122g comprises a substantially planar end plate 216 with first and second end plate surfaces 220, 222. The first end plate surface 220 is oriented away from the elongated portion 218, while the second end plate surface 222 is oriented toward the elongated portion 218. The end plate 216 further comprises one or more tabs end plate tabs 196 that extend from the first end plate surface 220. As with the previous embodiments, the end plate tabs 196 are preferably formed by cutting through the end plate 216 and bending the cut portion such that it protrudes from the first end plate surface 220. However, other methods for forming the end plate tabs 196 are also possible. The position and size of the end plate tabs 196 are designed so that they will fit within the slots 188 on the corner columns lOOg, lOlg, 102g, 103g, thereby allowing for attachment of the end connector 122g to the corner columns lOOg, lOlg, 102g, 103g.

[197] Referring to Fig. 52, an angle H of the end plate 216 with respect to the elongated member 218 should be substantially identical to the angle G. This would allow the end plate 216 to sit substantially flush against the first or second angled column walls 208, 210.

[198] As with the previous embodiments, the end plate 216 also preferably comprises one or more pin openings 200. The pin opening 200 allows beam pin 202 to be inserted through the end plate 216 and one of the slots 188. The beam pin 202 acts to secure the end plate 216 to the corner columns lOOg, lOlg, 102g, 103g and prevents the unintended detachment of the end plate 216 from the corner column lOOg, lOlg, 102g, 103g.

[199] Figs. 54 and 55 show a comparison between the different embodiments of the corner columns 100, 101, 102, 103. Fig. 54 shows one of the embodiments of the shelving system 10 with corner columns 100, 101 , 102, 103 having a generally rectangular cross-section. In such an embodiment, the support beams 104 stabilize the shelving system 10 in two directions only (as indicated by XI, X2). In comparison, Fig. 55 shows the embodiment of the shelving system lOg with the corner columns lOOg, lOlg, 102g, 103g having a generally triangular cross-section. In such an embodiment, the support beams 104g stabilize the shelving system lOg in four directions (as indicated by Yl, Y2, Y3, Y4). This stabilization in four directions results in additional stability for the shelving system lOg. [200] The slots 188 on the corner columns 100, 101 , 102, 103 may also be used for attachment of various accessories, as described below.

[201] Referring to Figs. 56 to 60, one or more shelving racks 1000 are provided. Preferably, two shelving racks 1000 are provided, as shown in Fig. 56. Referring to Figs. 57 and 58, each of the shelving racks 1000 comprises two brackets 1002 and a rack surface 1004 extending between the brackets 1002. The rack surface 1004 may be a solid surface or it may be a wire rack (as shown in Fig. 56). The rack surface 1004 is preferably generally flat and where the rack surface 1004 is a wire rack, it may be formed from a number of wires 1006 arranged in a grid-like pattern. The brackets 1002 comprise an upright member 1008, with an attachment flange 1010 and a support flange 1012 extending from the upright member 1008. Preferably, both the attachment flange 1010 and the support flange 1012 extend substantially perpendicularly from the upright member 1008. One or more rack tabs 1014 extends from the attachment flange 1010. The rack tabs 1014 are adapted to fit within the slots 188 on the corner columns 100, 101 , 102, 103 to provide for secure attachment of the shelving rack 1000 to the corner columns 100, 101, 102, 103.

[202] For example, the shelving rack 1000 may be attached to the corner columns 100, 101 (as shown in Fig. 56). The rack tabs 1014 of one of the attachment flanges 1010 will engage with the slots 188 on corner column 100, while the rack tabs 1014 of the other attachment flange 1010 will engage with the slots 188 on corner column 101. The attachment of the attachment flange 1010 to corner column 100 will now be described in detail; however, it is understood that the attachment of the attachment flange 1010 to corner column 101 is similar.

[203] When the attachment flange 1010 is attached to corner column 100, the attachment flange 1010 preferably sits against the central portion 184 (with the rack tabs 1014 fitted within the slots 188). The upright member 1008 preferably rests against one of the column walls 178, acting as a form of brace for the shelving rack 1000. A support brace 1016 may also be provided to provide support between the support flange 1012 and the upright member 1008. For example, in the embodiment shown in Figs. 56 to 59, the support brace 1016 comprises a generally triangular member that extends substantially perpendicularly from both the support flange 1012 and the upright member 1008. [204] The support flange 1012 preferably comprises one or more rack keyholes 1018. In the embodiment shown in Figs. 59 and 60, the bracket 1002 has two rack keyholes 1018. The rack keyholes 1018 comprise an enlarged portion 1020 and a locking portion 1022 and allow for the attachment of the rack surface 1004. The locking portion 1022 preferably has a smaller diameter than the enlarged portion 1020. The rack surface 1004 comprises one or more rack protrusions 1024. For example, in the embodiment shown in Figs. 59 and 60, the rack surface 1004 comprises four rack protrusions 1024. The rack protrusions 1024 preferably comprise an enlarged rack knob 1026 attached to a stem 1028. The stem 1028 is attached to the surface of the rack surface 1004. The rack knob 1026 preferably has a diameter that is less than that of the enlarged portion 1020 of the rack keyhole 1018, but greater than that of the locking portion 1022. The stem 1028 preferably has a diameter that is less than that of both the enlarged portion 1020 and the locking portion 1022. In order to attach the rack surface 1004 to the bracket 1002, the rack knobs 1026 are first inserted through the enlarged portions 1020. Then, the rack surface 1004 is moved laterally with respect to the brackets 1002 such that the stems 1028 are now within the locking portions 1022. Because the rack knobs 1026 have a greater diameter than that of the locking portions 1022, the rack surface 1004 is generally secured in place vertically.

[205] Referring to Fig. 56, two or more shelving racks 1000 may be arranged on top of each other. Because of the arrangement of the slots 188 on the corner columns 100, 101 , 102, 103, the vertical positions of the shelving racks 1000 may be adjusted in numerous ways. Where the rack surface 1004 is a wire rack, various tools or implements may be inserted through the shelving racks 1000. For example, a rake or broom (not shown) may be threaded through the shelving racks 1000 in order to hold the rake or broom in a substantially vertically orientation

[206] The attachment flange 1010 may further comprise one or more rack pin openings 1030 to allow the insertion of accessory pin 500. The accessory pin 500 helps to secure the shelving rack 1000 to the comer columns 100, 101 , 102, 103 and prevents the unintended detachment of the shelving rack 1000 from the corner columns 100, 101, 102, 103. The function of the accessory pin 500 will be described later.

[207] The shelving racks 1000 described above are generally suitable for corner columns 100, 101, 102, 103 where the central portion 184 is substantially planar. In other

embodiments of the corner columns 100, 101, 102, 103, the central portion 184 may not be necessarily substantially planar. For example, in the embodiment shown in Figs. 31 to 34 and previously described above, the central portion 184e comprises first and second angled surfaces 204, 206, with the first and second angled surfaces 204, 206 angled inwardly.

Because of this geometry of the corner columns lOOe, lOle, 102e, 103e, shelving racks 1000 will have to be altered accordingly.

[208] Figs. 61 and 62 show an embodiment of the shelving racks lOOOe to accommodate corner columns lOOe, lOle, 102e, 103e with inward-oriented first and second angled surfaces 204, 206. In this embodiment, the brackets 1002e are preferably altered to accommodate the first and second angled surfaces 204, 206. In particular, the attachment flange lOlOe is no longer substantially perpendicular to the upright member 1008e but instead forms an acute angle I, as best shown in Fig. 62. This angle I preferably corresponds to the angles C, D between the opposed column walls 178 and the first or second angled surfaces 204, 206. This allows the upright member 1008e and the attachment flange lOlOe to snugly fit over a portion of one of the corner columns lOOe, lOle, 102e, 103e for attachment. [209] In the embodiment shown in Figs. 38 to 41 and previously described above, the central portion 184f comprises first and second angled surfaces 204f, 206f, with the first and second angled surfaces 204f, 206f angled outwardly. Figs. 63 and 64 show another embodiment of the shelving racks lOOOf to accommodate such corner columns lOOf, lOlf, 102f, 103f with outward-oriented first and second angled surfaces 204f, 206f. In particular, the attachment flange 101 Of of the bracket 1002f is no longer substantially perpendicular to the upright member 1008f but instead forms an obtuse angle J, as best shown in Fig. 64. This angle J preferably corresponds to the angles E, F between the opposed column walls 178 and the first or second angled surfaces 204f, 206f. This allows the upright member 1008f and the attachment flange 101 Of to snugly fit over a portion of one of the corner columns lOOf, lOlf, 102f, 103f for attachment.

[210] Referring to Figs. 65 to 70, one or more door assemblies 2000 for attachment to the corner columns 100, 101, 102, 103 are provided. The door assembly 2000 comprises a door panel 2002, one or more hinge pins 2004, and one or more hinge plates 2006.

[21 1] Referring to Figs. 68 and 69, the hinge plate 2006 comprises first and second hinge members 2008, 2010, preferably arranged substantially perpendicularly to each other. A plurality of hinge tabs 2012 extend from the first hinge member 2008. The hinge tabs 2012 are adapted to fit within the slots 188 to provide for secure attachment of the hinge plate 2006 to one of the corner columns 100, 101, 102, 103. When the hinge plate 2006 is attached to the corner column 100, 101 , 102, 103, the first hinge member 2008 preferably sits against the central portion 184 (with the hinge tabs 2012 fitted within slots 188). The second hinge member 2010 preferably rests against one of the column walls 178, acting as a form of brace for the hinge plate 2006.

[212] The hinge plate 2006 preferably further comprises one or more first knuckles 2014. The first knuckles 2014 comprise a first tubular opening 2016 through which the hinge pin 2004 may be inserted.

[213] The door panel 2002 preferably comprises one or more second knuckles 2018. The second knuckles 2018 comprise a second tubular opening 2020 through which the hinge pin 2004 may be inserted.

[214] As shown in Fig. 70, the hinge pin 2004 is inserted through the first and second tubular openings 2016, 2020 in order to attach the door panel 2002 to the hinge plate 2006, while at the same time allowing for pivotable movement of the door panel 2002 with respect to the hinge plate 2006.

[215] The first hinge member 2008 may further comprise one or more hinge plate openings 2022 to allow the insertion of accessory pin 500. The accessory pin 500 helps to secure the hinge plate 2006 to the corner columns 100, 101 , 102, 103 and prevents the unintended detachment of the hinge plate 2006 from the corner columns 100, 101, 102, 103, as described later.

[216] As shown in Fig. 65, two door assemblies 2000 may be arranged on opposed corner columns (e.g. corner columns 100 and 102) so that a portion of the front of the shelving system 10 is covered by the door assemblies 2000. Because a plurality of the slots 188 are arranged vertically on the corner columns 100, 101, 102, 103, the vertical positions of the door assemblies 2000 may be adjusted. For example, the door assemblies 2000 may be moved either higher or lower on the shelving system 10 by detaching the door assemblies 2000 from the corner columns 100, 101 , 102, 103 and re-attaching them on the corner columns 100, 101, 102, 103 using slots 188 that are either higher or lower, respectively.

[217] Figs. 71 to 74 show another embodiment of the door assemblies 2000e to

accommodate the situation where the corner columns l OOe, lOle, 102e, 103e are in the embodiment shown in Figs. 31 to 34 and described earlier (i.e. the first and second angled surfaces 204, 206 are angled inwardly). In this embodiment, the hinge plates 2006e are altered to accommodate the altered geometry of the corner columns lOOe, lOle, 102e, 103e. In particular, the first and second hinge members 2008e, 2010e are no longer substantially perpendicular to each other, but now form an acute angle K, as best seen in Fig. 74. This angle K preferably corresponds to the angles C, D between the opposed column walls 178 and the first or second angled surfaces 204, 206. This allows the first hinge member 2008e to fit snugly over the corner columns lOOe, l Ole, 102e, 103e for attachment.

[218] Figs. 75 to 78 show another embodiment of the door assemblies 2000f to

accommodate the situation where the corner columns lOOf, lOlf, 102f, 103f are in the embodiment shown in Figs. 38 to 41 and described earlier (i.e. the first and second angled surfaces 204f, 206f are angled outwardly). In this embodiment, the hinge plates 2006f are altered to accommodate the altered geometry of the corner columns lOOf, l Olf, 102f, 103f. In particular, the first and second hinge members 2008f, 201 Of are no longer substantially perpendicular to each other, but now form an obtuse angle L, as best seen in Fig. 77. This angle L preferably corresponds to the angles E, F between the opposed column walls 178 and the first or second angled surfaces 204f, 206f. This allows the first hinge member 2008f to fit snugly over the corner columns lOOf, lOlf, 102f, 103f for attachment.

[219] Referring to Figs. 79 to 81, one or more hook plates 3000 for attachment to the corner columns 100, 101, 102, 103 are provided. In the example shown in Fig. 79, the hook plate 3000 is attached to corner columns 102 and 103. However, it is understood that the hook plate 3000 may also be attached to corner columns 100 and 101.

[220] Referring to Figs. 80 and 81 , the hook plate 3000 comprises first and second plate ends 3002, 3004. Each of the first and second plate ends 3002, 3004 comprises a plate attachment member 3006 and a plate support member 3008. The plate attachment member 3006 is preferably arranged substantially perpendicularly from the plate support member 3008. A plurality of plate tabs 3010 extends from the plate attachment member 3006. The plate tabs 3010 are adapted to fit within the slots 188 to provide for secure attachment of the hook plate 3000 to the corner columns 100, 101 , 102, 103. When the hook plate 3000 is attached to the corner columns 100, 101, 102, 103, the plate attachment member 3006 preferably sits against the central portion 184 (with the plate tabs 3010 fitted within slots 188). The plate support member 3008 preferably rests against one of the column walls 178, acting as a form of brace for the plate ends 3002, 3004.

[221] A central plate 3012 extends between the first and second plate ends 3002, 3004. One or more central plate slots 3014 are preferably formed on the central plate 3012. When the hook plate 3000 is attached to the corner columns (e.g. at corner columns 100 and 101), the central plate 3012 spans for substantially the depth of the shelving system 10. The central plate slots 3014 now face away from the sides of the shelving system 10, in a direction that is substantially perpendicular to the direction of the slots 188. This allows for hooks or other items to be attached to the central plate slots 3014 in a manner similar to that for the slots 188, except now these items may be attached to the sides of the shelving system 10.

[222] The central plate 3012 may also be removably attached to the first and second plate ends 3002, 3004. As with the shelving racks 2000, the first and second plate ends 3002, 3004 may comprise one or more plate keyholes 3016, and the central plate 3012 may comprise one or more plate protrusions 3018. The attachment of the central plate 3012 to the first and second plate ends 3002, 3004 would be similar to that of the rack surface 1004 to the bracket 1002 (through the use of the plate protrusion 3018 and the plate keyholes 3016).

[223] The plate attachment member 3006 may further comprise one or more plate openings 3020 to allow the insertion of accessory pin 500. The accessory pin 500 helps to secure the hook plate 3000 to the corner columns 100, 101 , 102, 103 and prevents the unintended detachment of the hook plate 3000 from the corner columns 100, 101 , 102, 103, as described later.

[224] Because of the arrangement of the slots 188, the vertical position of the hook plate 3000 may be adjusted. [225] Figs. 82 to 83 show another embodiment of the hook plate 3000e to accommodate the situation where the corner columns lOOe, lOle, 102e, 103e are in the embodiment shown in Figs. 31 to 34 and described earlier (i.e. the first and second angled surfaces 204, 206 are angled inwardly). The first and second hook plate ends 3002e, 3004e are altered to

accommodate the altered geometry of the corner columns lOOe, lOle, 102e, 103e. In particular, the plate attachment member 3006e is no longer substantially perpendicular to the plate support member 3008e, but they now instead form an acute angle M, as best seen in Fig. 83. This angle M preferably corresponds to the angles C, D between the opposed column walls 178 and the first or second angled surfaces 204, 206. This allows the plate attachment member 3006e to fit over the corner columns lOOe, lOle, 102e, 103e for attachment.

[226] Figs. 84 to 85 show another embodiment of the hook plate 3000f to accommodate the situation where the corner columns lOOf, lOlf, 102f, 103f are in the embodiment shown in Figs. 38 to 41 and described earlier (i.e. the first and second angled surfaces 204f, 206f are angled outwardly). The first and second hook plate ends 3002f, 3004f are altered to accommodate the altered geometry of the corner columns lOOf, lOlf, 102f, 103f. In particular, the plate attachment member 3006f is no longer substantially perpendicular to the plate support member 3008f, but they now instead form an obtuse angle N, as best seen in Fig. 85. This angle N preferably corresponds to the angles E, F between the opposed column walls 178 and the first or second angled surfaces 204 f, 206f. This allows the plate attachment member 3006 to fit over the corner columns lOOf, lOlf, 102f, 103f for attachment.

[227] Referring to Figs. 86 to 89, one or more pegboard assemblies 4000 for attachment to the corner columns 100, 101, 102, 103 are provided. The pegboard assembly 4000 comprises a pegboard 4002 with one or more pegboard brackets 4004 arranged on a periphery of the pegboard 4002. The pegboard 4002 preferably comprises a number of pegboard openings 4006 to allow for the attachment of various hooks or similar items. In the example shown in Figs. 86 and 87, the pegboard assembly 4000 is attached to corner columns 100 and 102, although it is understood that the pegboard assembly 4000 may also be attached to corner columns 101 and 103.

[228] The pegboard brackets 4004 comprise first and second bracket members 4008, 4010, preferably arranged substantially perpendicularly to each other. A plurality of bracket tabs 4012 extends from the first bracket member 4008. The bracket tabs 4012 are adapted to fit within the slots 188 to provide for secure attachment of the pegboard bracket 4004 to one of the corner columns 100, 101 , 102, 103. When the pegboard bracket 4004 is attached to the corner columns 100, 101, 102, 103, the first bracket member 4008 preferably sits against the central portion 184 (with the bracket tabs 4012 fitted within the slots 188). The second bracket member 4010 preferably rests against one of the column walls 178, acting as a form of brace for the pegboard bracket 4004.

[229] The pegboard bracket 4004 may comprise a third bracket member 4014 extending substantially perpendicularly from the second bracket member 4010. The pegboard 4002 may be attached to the third bracket member 4014. The attachment of the pegboard 4002 to the third bracket member 4014 may be by using keyholes and protrusions, similar to the attachment of the central plate 3012 to the first and second plate ends 3002, 3004 or the attachment of the rack surface 1004 to the bracket 1002.

[230] The first bracket member 4008 may further comprise one or more bracket openings 4016 to allow the insertion of accessory pin 900. The accessory pin 900 helps to secure the pegboard bracket 4004 to the corner columns 100, 101, 102, 103 and prevents the unintended detachment of the pegboard bracket 4004 from the corner columns 100, 101, 102, 103, as described later.

[231 ] Because of the arrangement of the slots 188, the vertical position of the pegboard brackets 4004 (and hence the pegboard assembly 4000) may be adjusted. [232] Where the pegboard assembly 4000 is not of sufficient width to span the entire width of the shelving system 10, two pegboard assemblies 4000, 4000' may be attached together, as shown in Fig. 90. The pegboard assemblies 4000, 4000 ' may be attached together using one or more pegboard ties 4018. The pegboard tie 4018 comprises a plurality of tie protrusions that are adapted to fit within pegboard keyholes located on the pegboard assemblies 4000, 4000 ' . The attachment of the pegboard tie 4018 to the pegboard assemblies 4000, 4000' would be similar to that of the rack surface 1004 to the bracket 1002 (through the use of the tie protrusions and the pegboard keyholes).

[233] Figs. 91 to 93 show another embodiment of the pegboard assembly 4000e to accommodate the situation where the corner columns lOOe, lOle, 102e, 103e are in the embodiment shown in Figs. 31 to 34 and described earlier (i.e. the first and second angled surfaces 204, 206 are angled inwardly). The pegboard brackets 4004e are altered to accommodate the altered geometry of the corner columns l OOe, l Ol e, 102e, 103e. In particular, the first and second bracket members 4008e, 401 Oe are no longer substantially perpendicular to each other, but now form an acute angle O, as best seen in Fig. 93. This angle O preferably corresponds to the angles C, D between the opposed column walls 178 and the first or second angled surfaces 204, 206. This allows the first bracket member 4008e to fit over the corner columns l OOe, lOle, 102e, 103e for attachment.

[234] Figs. 94 to 96 show another embodiment of the pegboard assembly 4000f to accommodate the situation where the corner columns lOOf, 10 If, 102f, 103f are in the embodiment shown in Figs. 38 to 41 and described earlier (i.e. the first and second angled surfaces 204f, 206f are angled outwardly). The pegboard brackets 4004f are altered to accommodate the altered geometry of the corner columns lOOf, lOlf, 102f, 103f. In particular, the first and second bracket members 4008f, 401 Of are no longer substantially perpendicular to each other, but now form an obtuse angle P, as best seen in Fig. 96. This angle P preferably corresponds to the angles E, F between the opposed column walls 178 and the first or second angled surfaces 204f, 206f. This allows the first bracket member 4008f to fit over the corner columns lOOf, lOlf, 102f, 103 f for attachment.

[235] Referring to Figs. 97 to 101, one or more wall ties 5000 to secure the shelving system 10 to a wall 600 are provided. The wall tie 5000 comprises a hook portion 5002 and an anchor portion 5004. Referring to Figs. 100 and 101, the hook portion 5002 is preferably attached to one of the support beams 104, while the anchor portion 5004 is secured to the wall 600. Preferably, the hook portion 5002 hooks over the lower horizontal face 1 16, thereby preventing the shelving system 10 from toppling forward. The anchor portion 5004 comprises an anchor opening 5006 to allow for a wall fastener 5008 to be used to secure the wall tie 5000 to the wall 600.

[236] Referring to Fig. 98, the anchor portion 5004 comprises first and second anchor members 5010, 5012. The anchor opening 5006 is located on the first anchor member 5010, while the second anchor member 5012 comprises an adjustment slot 5014. The adjustment slot 5014 is preferably elongated and is preferably sized to accommodate a bolt 5016. [237] The hook portion 5002 comprises a nut opening 5018 also preferably sized to accommodate the bolt 5016. The hook portion 5002 may slide along the second anchor member 5012 in order to adjust the relative distance between the hook portion 5002 and the first anchor member 5010. When the desired distance is attained, a nut 5020 may be threaded onto to the bolt 5016 and tightened to fix the position of the hook portion 5002 relative to the anchor portion 5004. A washer 5022 may also be provided to facilitate the contact of the nut 5020 with the second anchor member 5012.

[238] Referring to Figs. 102 and 103, there is provided the accessory pin 500, which is adapted to be inserted into one of the rack pin openings 1030, hinge plate openings 2022, plate openings 3020, or bracket openings 4016. The accessory pin 500 comprises first and second accessory pin ends 502, 504 and has a generally bent tubular shape caused by a bend 506, with a cap 508 preferably formed on the second accessory pin end 504.

[239] For example, for shelving rack 1000, when the first accessory pin end 502 is inserted into the rack pin opening 1030, the accessory pin 500 passes through the attachment flange 1010 and into one of the slots 188 on the corner columns 100, 101, 102, 103. Because of the bend 506, the accessory pin 500 cannot be inserted straight through the rack pin opening 1030. Instead, the accessory pin 500 must be maneuvered through the rack pin opening 1030 by guiding it along the curvature of the accessory pin 500. The cap 508 preferably has a diameter that is greater than the diameter of the rack pin opening 1030. Therefore, once movement of the accessory pin 500 reaches the second pin end 504, the cap 508 will prevent the accessory pin 500 from passing through any further. Once the accessory pin 500 has been fully inserted, the bend 506 prevents the accessory pin 500 from easily falling out, thus providing a degree of security for the attachment of the shelving rack 1000 to the corner columns 100, 101, 102, 103. [240] Preferably, the accessory pin 500 further comprises a pin notch 510 formed on the accessory pin 500 proximate to the cap 508. The pin notch 510 allows the cap 508 to sit substantially flush against the attachment flange 1010 when the accessory pin 500 has been inserted fully through the rack pin opening 1030. The pin notch 510 prevents the accessory pin 500 from sliding about. [241] Similarly, for door assembly 2000, when the first accessory pin end 502 is inserted into the hinge plate opening 2022, the accessory pin 500 passes through the attachment flange 2008 and into one of the slots 188 on the corner columns 100, 101 , 102, 103. Because of the bend 506, the accessory pin 500 cannot be inserted straight through the hinge plate opening 2022 but instead must be maneuvered through the hinge plate opening 2022 by guiding it along the curvature of the accessory pin 500. The cap 508 preferably has a diameter that is greater than the diameter of the hinge plate opening 2022. Once the accessory pin 500 has been fully inserted, the bend 506 prevents the accessory pin 500 from easily falling out, thus providing a degree of security for the attachment of the door assembly 2000 to the corner columns 100, 101, 102, 103.

[242] For hook plate 3000, when the first accessory pin end 502 is inserted into the plate opening 3020, the accessory pin 500 passes through the plate attachment member 3006 and into one of the slots 188 on the corner columns 100, 101 , 102, 103. Because of the bend 506, the accessory pin 500 cannot be inserted straight through the plate opening 3020 but instead must be maneuvered through the plate opening 3020 by guiding it along the curvature of the accessory pin 500. The cap 508 preferably has a diameter that is greater than the diameter of the plate opening 3020. Once the accessory pin 500 has been fully inserted, the bend 506 prevents the accessory pin 500 from easily falling out, thus providing a degree of security for the attachment of the hook plate 3000 to the corner columns 100, 101, 102, 103. [243] Referring to Fig. 103, for pegboard assembly 4000, when the first accessory pin end 502 is inserted into the bracket opening 4016, the accessory pin 500 passes through the first bracket member 4008 and into one of the slots 188 on the corner columns 100, 101, 102, 103. Because of the bend 506, the accessory pin 500 cannot be inserted straight through the bracket opening 4016 but instead must be maneuvered through the bracket opening 4016 by guiding it along the curvature of the accessory pin 500. The cap 508 preferably has a diameter that is greater than the diameter of the bracket opening 4016. Once the accessory pin 500 has been fully inserted, the bend 506 prevents the accessory pin 500 from easily falling out, thus providing a degree of security for the attachment of the pegboard assembly 4000 to the corner columns 100, 101, 102, 103. [244] The beam pin 202 may act in a similar manner to the accessory pin 500. Referring to Fig. 103, the beam pin 202 is shown securing the support beam 104 to the corner column 102. [245] It will be appreciated by those skilled in the art that the preferred embodiments have been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
