Referring to FIGS. 1 to 7, the present application provides a shelving apparatus 100 including shelving members 110, horizontal support members 120, vertical support members 130 and structural support members 140.

The shelving members 110 are used to store items. The horizontal support members 120 are used to support the shelving members 110. The horizontal support members 120 include first horizontal beams 121 and the second horizontal beams 122, which are arranged in opposition horizontally. The vertical support members 130 are used to support the first horizontal beams 121 and the second horizontal beams 122. The vertical support members 130 include first vertical posts 131 and second vertical posts 132, which are in opposition horizontally.

The structural support members 140 include vertical-post bracing struts 141 arranged between the first vertical posts 131 and the second vertical posts 132. The structural support members 140 function for structural reinforcement of the horizontal support members 120 and the vertical support members 130.

Shelving apparatuses, such as racks, are mostly presented as separate components during transportation and sales. After purchasing the components, consumers need to assemble the components into final products by themselves. During the assembly of an existing product, securing of vertical posts and vertical-post bracing struts requires at least two persons to work in coordination, or the vertical posts must be placed horizontally on the ground in order to enable the assembly. For ordinary consumers, such assembly approaches are not convenient.

According to the present application, one ends of the vertical-post bracing struts 141 are provided with locating mechanisms 150, which can locate the one ends of the vertical-post bracing struts 141 at predetermined locations on the first vertical posts 131, ensuring accurate assembly and positioning of the first vertical posts 131 and the vertical-post bracing struts 141. This dispenses with the need for support by an assembler's hands, resulting in increases in operational efficiency and simplicity and ease of implementation.

Referring to FIGS. 1 to 7, a shelving apparatus 100 according to one embodiment includes shelving members 110, horizontal support members 120, vertical support members 130 and structural support members 140.

The shelving apparatus 100 is generally a frame structure composed of the horizontal support members 120 and the vertical support members 130. As used herein, the term “longitudinal” refers to a lengthwise direction of the frame structure as indicated by arrow X of FIG. 1. “Horizontal” refers to a widthwise direction of the frame structure as indicated by arrow Y of FIG. 1. “Vertical” refers to a heightwise direction of the frame structure as indicated by arrow Z of FIG. 1. “Upward” refers to a direction coincident with the arrow Z of FIG. 1. “Downward” refers to a direction opposite to arrow Z of FIG. 1.

The shelving members 110 may be arranged in one or more layers and are used to store items.

The shelving members 110 may be shelf plates or wire mesh shelves. The shelf plates are plate-like components made of metal, plastic or the like and are advantageous in that items stored thereon will not easily fall off. The wire mesh shelves are mesh-like components each composed of multiple longitudinal wires and multiple transverse wires and are advantageous in being light in weight and making material savings. Preferably, the longitudinal and transverse wires are steel wires. The wire mesh shelves may be manufactured by welding the multiple longitudinal wires to the multiple transverse wires.

Correspondingly, the horizontal support members 120 may be arranged in one or more layers, and are used to support the shelving members 110. The horizontal support members 120 may include first horizontal beams 121 and second horizontal beams 122, which are arranged in opposition horizontally. The first horizontal beams 121 and the second horizontal beams 122 have support surfaces for supporting the shelving members 110. The support surfaces of the first horizontal beams 121 and the second horizontal beams 122 are in the same plane(s) as the respective layer(s) of shelving members 110 and serve to support the shelving members 110.

The vertical support members 130 are used to support the horizontal beam 121. The vertical support members 130 may include first vertical posts 131 and second vertical posts 132, which are in opposition horizontally.

The structural support members 140 include vertical-post bracing struts 141 provided between the first vertical posts 131 and second vertical posts 132. The vertical-post bracing struts 141 may include horizontal bracing struts 142 and oblique bracing struts 143. The horizontal bracing struts 142 are horizontally provided between the first vertical posts 131 and the second vertical posts 132. The oblique bracing struts 143 are obliquely provided between the first vertical posts 131 and the second vertical posts 132. For example, one ends of the oblique bracing struts 143 are provided at lower ends of the first vertical posts 131, and the other ends thereof are provided at upper ends of the second vertical posts 132. The vertical-post bracing struts 141 can enhance the stability of the first vertical posts 131 and the second vertical posts 132.

Further, the structural support members 140 also include horizontal-beam bracing struts 144 provided between the first horizontal beams 121 and the second horizontal beams 122. The horizontal-beam bracing struts 144 can enhance the stability of the first horizontal beams 121 and the second horizontal beams 122.

One ends of the vertical-post bracing struts 141 are provided with locating mechanisms 150, which can locate the one ends of the vertical-post bracing struts 141 at predetermined locations on the first vertical posts 131, ensuring accurate assembly and positioning of the first vertical posts 131 and the vertical-post bracing struts 141. This dispenses with the need for support by an assembler's hands, resulting in increases in operational efficiency and simplicity and ease of implementation.

The other ends of the vertical-post bracing struts 141 can be switched between first positions where they are received in the first vertical posts 131 (as shown in FIG. 11) and second positions where they are assembled with the second vertical posts (as shown in FIG. 12), facilitating assembly of the vertical-post bracing struts 141.

Referring to FIG. 11, the vertical-post bracing struts 141 are horizontal bracing struts, for example. During transportation and sales of the shelving apparatus, the one ends of the vertical-post bracing struts 141 may be located at the predetermined locations on the first vertical posts 131. First holes 1311 may be formed in the first vertical posts 131 at the predetermined locations. The other ends of the vertical-post bracing struts 141 may be pivoted about the first holes 1311 in the first vertical posts 131 so that the vertical-post bracing struts 141 are received in the first vertical posts 131. In this way, the vertical-post bracing struts 141 are in the first positions where they are folded and hidden with the vertical-post bracing struts 141.

Referring to FIG. 12, in order to assemble the vertical-post bracing struts 141, the other ends of them are pivoted about the first holes 1311 in the first vertical posts 131 until they are oriented horizontally. In this way, the vertical-post bracing struts 141 are at the second positions where the vertical-post bracing struts 141 are unfolded, with the other ends being ready for assembly with the second vertical posts.

In one embodiment, referring to FIGS. 4 and 7 to 12, the locating mechanisms 150 include first engagement members 151. The first engagement members 151 are elastic. For example, they may be plastic parts. The first engagement members 151 match the vertical-post bracing struts 141 in both cross-sectional shape and size. The first engagement members 151 can engage outside the one ends of the vertical-post bracing struts 141.

Cross-sections of the vertical-post bracing struts 141 are generally inverted U-shaped. The vertical-post bracing struts 141 each include a first bottom wall 1412 and two opposing first side walls 1413. Second holes 1411 are formed in the first side walls 1413 at the one ends of the vertical-post bracing struts 141.

The first engagement members 151 each include a second bottom wall 1511 and two opposing second side walls 1512. The first engagement members 151 further include first guide portions 1513 provided inside the first engagement members 151 on the second bottom walls 1511, leaving first gaps 1514 between the first guide portions 1513 and the second side walls 1512 of the first engagement members 151. The first gaps 1514 match the first side walls 1413 of the vertical-post bracing struts 141 in size, allowing the first side walls 1413 of the vertical-post bracing struts 141 to engage between the first guide portions 1513 and the second side walls 1512 of the first engagement members 151.

Third holes 1515 are formed in the first guide portions 1513, and fourth holes 1516 are formed in the second side walls 1512 at corresponding locations. When the first engagement members 151 engage the first vertical posts 131, the first holes 1411, the second holes 1311, the third holes 1515 and the fourth holes 1516 are located on the same axes L1, and the vertical-post bracing struts 141 can be secured to the first vertical posts 131 using first fasteners 153. The first fasteners 153 may be bolts, screws and pins.

This perforated design of the first guide portions 1513 can facilitate accurate mounting of the bolts, screws and pins.

The locating mechanisms 150 further include second engagement members 152. The second engagement members 152 are elastic, and are leaf springs or plastic parts, for example. The second engagement members 152 include first protrusions 1521 and second protrusions 1522. Locating holes 1312 are provided in the first vertical posts 131 at locations corresponding to the first protrusions 1521. The first protrusions 1521 can engage in the locating holes 1312 to locate the second engagement members 152 at the predetermined locations on the first vertical posts 131. The second protrusions 1522 are arranged so as to be oriented toward the second side walls 1512 of the first engagement members 151. In the first positions where the other ends of the vertical-post bracing struts 141 are received in the first vertical posts 131 (as shown in FIG. 11) and in the second positions where the other ends of the vertical-post bracing struts 141 are assembled with the second vertical posts (as shown in FIG. 12), the second protrusions 1522 abut against one sides of the first engagement members 151, securing the vertical-post bracing struts 141 against the first vertical posts 131.

Assembly of conventional vertical-post bracing struts 141 and first vertical posts 131 would require manual alignment and mounting. Now, with the first engagement members 151 and the second engagement members 152, the first vertical posts 131 can be located relative to the vertical-post bracing struts 141 so that corresponding holes therein are aligned, facilitating mounting of the fasteners. Specifically, the first engagement members 151 may be assembled and engaged (optionally, pre-assembled) with the one ends of the vertical-post bracing struts 141, and the second engagement members 152 may be assembled and engaged (optionally, pre-assembled) with the vertical posts 131. The first engagement members 151 and the second engagement members 152 may engage with each other to locate the vertical-post bracing struts 141 relative to the first vertical posts 131.

The first engagement members 151 are provided with the first guide portions 1513 and match the inverted U-shaped cross-sections of the vertical-post bracing struts 141. In addition, the use of the elastic plastic parts and elastic elements, such as leaf springs, additionally facilitates the engagement between the protruding and recessed components.

In one embodiment, referring to FIG. 9 and 13a to 13c, the locating mechanisms 150 include first engagement members 151. The first engagement members 151 are elastic. For example, they may be plastic parts. The first engagement members 151 match the vertical-post bracing struts 141 in both cross-sectional shape and size. The first engagement members 151 can engage outside the one ends of the vertical-post bracing struts 141.

The first holes 1311 may be formed on opposite sides of the first vertical posts 131 at the predetermined locations.

Cross-sections of the vertical-post bracing struts 141 are generally inverted U-shaped. The vertical-post bracing struts 141 each include a first bottom wall 1412 and two opposing first side walls 1413. Second holes 1411 are formed on opposite sides of the first side walls 1413 at the one ends of the vertical-post bracing struts 141.

Referring to FIG. 13c, the first engagement members 151 each include a second bottom wall 1511 and two opposing second side walls 1512. The first engagement members 151 further include first guide portions 1513 provided inside the first engagement members 151 on the second bottom walls 1511, leaving first gaps 1514 between the first guide portions 1513 and the second side walls 1512 of the first engagement members 151. The first gaps 1514 match the first side walls 1413 of the vertical-post bracing struts 141 in size, allowing the first side walls 1413 of the vertical-post bracing struts 141 to engage between the first guide portions 1513 and the second side walls 1512 of the first engagement members 151.

Third holes 1515 are formed in the first guide portions 1513, and fourth holes 1516 are formed in the second side walls 1512 at corresponding locations. When the first engagement members 151 engage the first vertical posts 131, the first holes 1411, the second holes 1311, the third holes 1515 and the fourth holes 1516 are located on the same axes L1, and the vertical-post bracing struts 141 can be secured to the first vertical posts 131 using first fasteners 151.

In this embodiment, the first fasteners 151 include rivets 155 and bolts 156. The rivets 155 may be rivet nuts. The rivets 155 are successively passed through the second holes 1311 on one sides of the first vertical posts 131 and the fourth holes 1516 on one sides of the first engagement members 151, securing the first engagement members 151 to the first vertical posts 131. Third gaps 1517 are left between head portions of the rivets 155 and the first guide portions 1513. The third gaps 1517 match the first side walls 1413 of the vertical-post bracing struts 141 in size, allowing the first side walls 1413 of the vertical-post bracing struts 141 to engage between the first guide portions 1513 and the head portions of the rivets 155. After the vertical-post bracing struts 141 are engaged in the first engagement members 151, the bolts 156 are successively passed through the second holes 1311 on the other sides of the first vertical posts 131, the fourth holes 1516 on the other sides of the first engagement members 151 and the third holes 1515 in the first guide portions 1513 and screwed onto threads of the rivets 155, thereby securing the vertical-post bracing struts 141 to the first vertical posts 131.

In one embodiment, referring to FIGS. 14a and 14b, the vertical-post bracing struts 141 are horizontal bracing struts, for example. One ends of the vertical-post bracing struts 141 are located at predetermined locations on the first vertical posts 131. First holes 1311 are formed in the first vertical posts 131 at the predetermined locations. The locating mechanisms 150 include third engagement members 154. The third engagement members 154 are elastic, and are plastic parts, for example. The third engagement members 154 include receiving portions 1541 and engaging portions 1542. One ends of the receiving portions 1541 match the vertical-post bracing struts 141 in both cross-sectional shape and size and can engage outside one ends of the vertical-post bracing struts 141. The engaging portions 1542 may be vertically provided at the other ends of the receiving portions 1541. In some other embodiments, for example, when the vertical-post bracing struts 141 are oblique bracing struts, the engaging portions 1542 may be obliquely provided at the other ends of the receiving portions 1541 so that, when the engaging portions 1542 are located at the predetermined locations on the first vertical posts 131, the receiving portions 1541 are oriented at the same angle as the vertical-post bracing struts 141 assembled with the second vertical posts in the second positions.

Referring to FIG. 9, cross-sections of the vertical-post bracing struts 141 are generally inverted U-shaped. The vertical-post bracing struts 141 each include a first bottom wall 1412 and two opposing first side walls 1413. Second holes 1411 are formed in first side walls 1413 at the one ends of the vertical-post bracing struts 141.

Referring to FIGS. 14a and 14b, the receiving portions 1541 each include a third bottom wall 1543 and two opposing third side walls 1544. The receiving portions 1541 further include second guide portions 1545, which are provided inside the receiving portions 1541 on the third bottom walls 1543, leaving second gaps 1546 between the second guide portions 1545 and the third side walls 1544 of the receiving portions 1541. The second gaps 1546 match the first side walls 1413 of the vertical-post bracing struts 141 in size, allowing the first side walls 1413 of the vertical-post bracing struts 141 to engage between the second guide portions 1545 and the third side walls 1544 of the receiving portions 1541. The engaging portions 1542 include third protrusions 1547, and locating holes 1312 are provided in the first vertical posts 131 at locations corresponding to the third protrusions 1547. The third protrusions 1547 can engage in the locating holes 1312 to locate the engaging portions 1542 at the predetermined locations on the first vertical posts 131.

Fifth holes 1548 are formed in the second guide portions 1545, and sixth holes 1549 are formed in the third side walls 1544 at corresponding locations. When the third engagement members 154 engage the first vertical posts 131, the first holes 1311, the second holes 1411, the fifth holes 1548 and the sixth holes 1549 are located on the same axes L2, and the vertical-post bracing struts 141 may be secured against the first vertical posts 131 using first fasteners. The first fasteners may be bolts, screws or pins.

This perforated design of the second guide portions 1545 can facilitate accurate mounting of the bolts, screws and pins.

In some embodiments, the vertical-post bracing struts 141 may directly contact and, be closely fitted against, the vertical posts. For example, engagement recesses and protrusions may be provided between the vertical-post bracing struts 141 and the vertical posts to allow them to be located, ensuring their accurate mounting and secure connection.

Referring to FIGS. 16, 18 and 20, in order to assemble the vertical-post bracing struts 141, the one ends of the vertical-post bracing struts 141 may be located at the predetermined locations of the first vertical posts 131, and the other ends of the vertical-post bracing struts 141 may be assembled with the second vertical post at corresponding locations. When the vertical-post bracing struts 141 are horizontal bracing struts, they are horizontally arranged so that their other ends can be connected to the second vertical posts at the corresponding locations. At this time, the vertical-post bracing struts 141 are in the second positions. When the vertical-post bracing struts 141 are oblique bracing struts, they are obliquely arranged so that their other ends can be connected to the second vertical posts at the corresponding locations. At this time, the vertical-post bracing struts 141 are in the second positions.

In one embodiment, referring to FIGS. 15 to 17, the locating mechanisms 150 include fourth protrusions 1414 and first recesses 1313, which correspond to each other. The fourth protrusions 1414 and the first recesses 1313 are provided on the vertical-post bracing struts 141 and the first vertical posts 131, respectively. When the one ends of the vertical-post bracing struts 141 are located at the predetermined locations on the first vertical posts 131, and when the other ends of the vertical-post bracing struts 141 are located so that they can be assembled with the second vertical posts in the second positions, the fourth protrusions 1414 are located in correspondence with the first recesses 1313. During assembly, locating of the vertical-post bracing struts 141 and the first vertical posts 131 is accomplished by mating of the fourth protrusions 1414 with the first recesses 1313.

In one embodiment, referring to FIGS. 18 to 19, the locating mechanisms 150 are each provided with two fifth protrusions 1314 on a first vertical post 131. When the one ends of the vertical-post bracing struts 141 are located at the predetermined locations on the first vertical posts 131, and when the other ends of the vertical-post bracing struts 141 are located so that they can be assembled with the second vertical posts in the second positions, the two fifth protrusions 1314 are located above and under the one end of a vertical-post bracing strut 141, respectively. The two fifth protrusions 1314 may be formed by stamping. During mounting of the vertical-post bracing strut 141, the two fifth protrusions 1314 can serve to secure it at a predetermined height.

In one embodiment, referring to FIGS. 20 to 21, the locating mechanisms 150 include tongues 1315 provided on the first vertical posts 131. When the one ends of the vertical-post bracing struts 141 are located at the predetermined locations on the first vertical posts 131, and when the other ends of the vertical-post bracing struts 141 are located so that they can be assembled with the second vertical posts in the second positions, the tongues 1315 are located under one ends of the vertical-post bracing struts 141. The tongues 1315 may be formed by punching and L-shaped. During mounting of the vertical-post bracing strut 141, the tongues 1315 can serve to secure them at predetermined height(s).

In some embodiments, one ends of the horizontal-beam bracing struts 144 are provided with locating mechanisms, which can locate the one ends of the horizontal-beam bracing struts 144 at predetermined locations on the first horizontal beams 121. The other ends of the horizontal-beam bracing struts 144 can be switched between third positions where they are received in the first horizontal beams 121 and fourth positions where they are assembled with the second horizontal beams 122. The locating mechanisms provided at the one ends of the horizontal-beam bracing struts 144 are structurally and functionally similar to the locating mechanisms 150 provided at the one ends of the vertical-post bracing struts 141, further description thereof is deemed unnecessary and omitted here.

In one embodiment, referring to FIGS. 1 to 7, a shelving apparatus 100 includes shelving members 110, horizontal support members 120 and vertical support members 130.

The shelving apparatus 100 is generally a frame structure composed of the horizontal support members 120 and the vertical support members 130. The shelving members 110 may be arranged in one or more layers and are used to store items.

The shelving members 110 may be shelf plates or wire mesh shelves. The shelf plates are plate-like components made of metal, plastic or the like and are advantageous in that items stored thereon will not easily fall off. The wire mesh shelves are mesh-like components each composed of multiple longitudinal wires and multiple transverse wires and are advantageous in being light in weight and making material savings. Preferably, the longitudinal and transverse wires are steel wires. The wire mesh shelves may be manufactured by welding the multiple longitudinal wires to the multiple transverse wires.

Correspondingly, the horizontal support members 120 may be arranged in one or more layers, and are used to support the shelving members 110. The horizontal support members 120 may include first horizontal beams 121 and second horizontal beams 122, which are arranged in opposition horizontally. The first horizontal beams 121 and the second horizontal beams 122 have support surfaces for supporting the shelving members 110. The support surfaces of the first horizontal beams 121 and the second horizontal beams 122 are in the same plane(s) as the respective layer(s) of shelving members 110 and serve to support the shelving members 110.

The vertical support members 130 are used to support the horizontal beam 121. The vertical support members 130 may include first vertical posts 131 and second vertical posts 132, which are in opposition horizontally.

Referring to FIGS. 22 to 25, the shelving members 110 can be horizontally folded.

In one embodiment, referring to FIG. 22, the shelving members 110 include first shelf plates 111 and second shelf plates 112. The first shelf plates 111 and the second shelf plates 112 are rotatably connected by connecting portions 113. The connecting portions 113 may be hinges.

Wire mesh shelves are commonly used in shelving apparatuses. However, they are bulky and inconvenient to transport and store. There are foldable wire mesh shelves which can be folded into a size not exceeding an aggregate width of four vertical posts. After being folded, such wire mesh shelve can be piled up with vertical posts, horizontal beams, vertical-post bracing struts, horizontal-beam bracing struts and other components, greatly reducing the package size and facilitating storage.

In one embodiment, referring to FIGS. 23 and 24, the shelving members 110 each include a first wire mesh shelf 114 and a second wire mesh shelf 115. The first wire mesh shelf 114 and the second wire mesh shelf 115 are rotatably connected by connecting portions 113. The first wire mesh shelf 114 and the second wire mesh shelf 115 each include multiple longitudinal wires 116 and multiple transverse wires 117.

In one embodiment, referring to FIG. 25, the shelving members 110 each include a first wire mesh shelf 114, a second wire mesh shelf 115 and a third wire mesh shelf 118, which are connected in sequence. Each pair of the wire mesh shelves is rotatably connected by connecting portions 113. In other embodiments, the number of wire mesh shelves may be more than three.

In one embodiment, referring to FIGS. 26 and 27, the connecting portions 113 each include a first connecting sheet 1131 and a second connecting sheet 1132. The first connecting sheet 1131 and the second connecting sheet 1132 respectively have opposing curved concave surfaces, which can be engaged to define two channels. The two channels engage respective adjacent two longitudinal wires 116 respectively in the first wire mesh shelf 114 and the second wire mesh shelf 115. Secured and restricted by a second fastener 1133, the two longitudinal wires 116 will not disengage from the two channels.

In one embodiment, referring to FIGS. 28 to 30, the connecting portions 113 each include a connecting engagement member 1134 and a restricting engagement member 1135. The connecting engagement member 1134 is a hollow channel open at the bottom, and the restricting engagement member 1135 is a bar-like member matching the interior of the connecting engagement member 1134 both in shape and size. The restricting engagement member 1135 defines indentations at its respective two upper corners. An engagement block 1136 is provided on the restricting engagement member 1135, and an engagement slot 1137 is provided in the connecting engagement member 1134 at a location corresponding to the engagement block 1136. When the restricting engagement member 1135 is inserted in the connecting engagement member 1134, and when the engagement block 1136 engages the engagement slot 1137, between the connecting engagement member 1134 and the restricting engagement member 1135, spaces are delimited, in which adjacent two longitudinal wires 116 respectively in the first wire mesh shelf 114 and the second wire mesh shelf 115 can be received.

In one embodiment, referring to FIG. 31, the connecting portions 113 each include a first engagement hook 1138 and a second engagement hook 1139, which are joined to each other and define openings in opposition. The first engagement hooks 1138 engage one longitudinal wire 116 in the first wire mesh shelf 114, and the second engagement hooks 1139 engage an adjacent longitudinal wire 116 in the second wire mesh shelf 115. In this way, the adjacent two longitudinal wires 116 are retained in the first engagement hooks 1138 and the second engagement hooks 1139 without disengagement.

Referring to FIG. 32, the transverse wires 117 in the first wire mesh shelf 114 are in opposition to those in the second wire mesh shelf 115. If the connecting portions 113 have an insufficient size, a gap δ between the transverse wires 117 would be too small to allow the first wire mesh shelf 114 and the second wire mesh shelf 115 to be completely folded upwards. Consequently, they would have to be folded downwards (as indicated by the dashed arrows). In order to avoid this, the size of the connecting portions 113 is designed so that the gap δ between the transverse wires 117 in the first wire mesh shelf 114 and the second wire mesh shelf 115 are large enough to allow the first wire mesh shelf 114 and the second wire mesh shelf 115 to be completely folded upwards.

In one embodiment, referring to FIG. 33, the transverse wires 117 in the first wire mesh shelf 114 are extended to define third engagement hooks 1140, which match with an adjacent longitudinal wire 116 in the second wire mesh shelf 115 so that the longitudinal wire 116 is received in the third engagement hooks 1140 without disengaging therefrom.

In one embodiment, referring to FIGS. 34 to 38, pairs of transverse wires 117 in the first wire mesh shelf 114 are extended, bent and joined to define closed first bent portions 1141, and pairs of transverse wires 117 in the second wire mesh shelf 115 are extended, bent and joined to define closed second bent portions 1142. The first bent portions 1141 match the second bent portions 1142 in shape so that they can engage together to avoid disengagement of the first wire mesh shelf 114 and the second wire mesh shelf 115.

The first bent portions 1141 and the second bent portions 1142 may assume any suitable shapes known in the art to be engageable with each other. In this embodiment, in the first wire mesh shelf 114, some of the transverse wires 117 are each horizontally extended to define a first portion 11411, downward bent to define a second portion 11412, longitudinally bent to define a third portion 11413, upwardly bent to define a fourth portion 11414 and then joined to a horizontally extending fifth portion 11415 of another transverse wire 117 to define a closed first bent portion 1141. In the second wire mesh shelf 115, some of the transverse wires 117 are each horizontally extended to define a sixth portion 11421, downwardly bent to define a seventh portion 11422, backwardly and then upwardly bent to define a first concave engagement feature 11423, longitudinally bent to define an eighth portion 11424, downward bent and extended to define a second concave engagement feature 11425, upwardly bent to define a ninth portion 11426 and then joined to a horizontally extending tenth portion 11427 of another transverse wire 117 to define a closed second bent portions 1142. The first concave engagement features 11423 and the second concave engagement features 11425 of the second wire mesh shelf 115 can engage the third portions 11413 of the first wire mesh shelf 114 to avoid disengagement of the first wire mesh shelf 114 and the second wire mesh shelf 115.

In one embodiment, referring to FIG. 38, first bent portions 1141 and second bent portions 1142 may be alternately arranged on a longitudinal edge 119 of the first wire mesh shelf, and second bent portions 1142 and first bent portions 1141 may be alternately arranged on a corresponding longitudinal edge 119 of each second wire mesh shelves. Each first bent portion 1141 in the first wire mesh shelf can engage with a corresponding second bent portion 1142 in the second wire mesh shelf, and each second bent portion 1142 in the first wire mesh shelf can engage with a corresponding first bent portion 1141 in the second wire mesh shelf.

In one embodiment, referring to FIGS. 39 to 44, after being folded, the shelving members 110 can be piled up in a horizontally orientation with the vertical posts 131 and the horizontal beams 121. In this embodiment, the resulting pile, as a whole, has a width W lying between 370 mm and 420 mm.

After being folded, each shelving member 110 is approximately as wide as four vertical posts 131, or as four horizontal beams 121. The shelving members 110, vertical posts 131 and horizontal beams 121 may be piled up in a single package, resulting in reductions in transportation cost and package volume.

In one embodiment, referring to FIG. 39, each horizontal beam 121 is provided at its opposite ends with respective connecting features 1210.
