DETAILED DESCRIPTION
(6) In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.
(7) One embodiment of the invention is a utility rack with end supports having folding cross members. The utility rack with these end supports allows for compact packaging and storage, easy assembly and high rigidity and strength when fully assembled.
(8)
(9) In one embodiment of the invention, each end support 110 of the rack 100 comprises two vertical supports and one or more cross-members. In an embodiment, the one or more cross-members couple, variously, to the two vertical supports at a first attachment point 126, a second attachment point 128, a third attachment point 130, and a fourth attachment point 132.
(10) The first vertical support 210 includes one or more cross members 222, 224, 226. As described below, the cross members 222, 224, 226 are designed to be movable between a first collapsed position and a second extended position. In the second extended position, the cross members are connectable to a second vertical support to form a rack end support 110.
(11) As shown in
(12) The cross members 222, 224, 226 are mounted to the first vertical support 210, and most preferably are permanently affixed or connected to the first vertical support 210. At the same time, the cross members 222, 224, 226 are configured to be foldable or pivotable relative to the first vertical support 210. In one embodiment, the cross members 222, 224, 226 are mounted to the vertical supports by one or more cross member mounts or other attachment mechanisms. Particularly, brackets 230 or other mounts are provided that are mounted or connected to the first vertical support 210. In one embodiment, the brackets 230 include tabs or other elements which connect to one or more of the fastening apertures 214 in the channel 212 of the vertical support 210. The brackets 230 may be fixed to the fastening apertures 214 via any suitable connection providing sufficient strength and rigidity such as by a force fit, fasteners, and the like. Alternatively, the brackets 230 may be welded within the channel 212 of the first vertical support 210, or may be formed integrally with the first vertical support 210.
(13) In a preferred embodiment, each bracket 230 includes a pair of spaced flanges 234 each having an aperture 232 configured to receive at least one fastener. The fastener, such as a pin, bolt or the like may be configured to extend through the apertures 232 and corresponding apertures in a first end of the cross members 222, 224, 226. The pin may be force fit into the apertures 232 to secure the pin to the bracket 230, or the pin may be a bolt that has a corresponding nut to secure the pin to the bracket 230. It is also possible to utilize two pins, each of which engages one of the flanges and one portion of the first end of the cross members 222, 224, 226. The rotatable connection between the cross members 222, 224, 226 and the brackets 230 allows the cross member 222, 224, 226 to rotate or fold with respect to the first vertical support 210.
(14) In this embodiment, there is a lower horizontal cross member 224, an upper horizontal cross member 226, and a diagonal cross member 222. In a preferred embodiment, each cross member 222, 224, 226 is also generally U or C shaped in cross-sectional shape, thus including a pair of spaced apart walls 236. The U or C shape of the of horizontal or diagonal cross members, as described above, forms a channel with an open side. In some embodiments, the channels are positioned to open in a certain direction indicated by arrows 241 in
(15) In one embodiment, a first end of the lower horizontal cross member 224 and a first end of the diagonal cross member 222 are permanently attached to the first vertical support 210 at a first position via a first bracket 230, and a first end of the upper cross member 226 is permanently attached to the vertical support 210 at a second position via a second bracket 230, as shown in
(16) As indicated, each end support 110 of the rack 110 preferably also includes a second vertical support 310. In a preferred embodiment, the second vertical support 310 also comprises an elongate member having a first end and a second end. The second vertical support 310 may also include one or more attachment points or members, such as for attaching the shelving 120 or shelving supports 122. Preferably, the second vertical support 310 does not include any cross members. Instead, the second vertical support 310 only includes one or more brackets 330 or similar members to which the free ends of the cross members 222, 224, 226 of the first vertical support 210 may be selectively connected and disconnected (i.e. the end supports 110 include means for removably connecting the cross members 222, 224, 226 to the second vertical support 310), as described below.
(17)
(18) As illustrated in
(19) As shown in
(20) The free ends of the cross members 222, 224, 226 are connected to the brackets 330 of the second vertical support 310. The brackets 330 may be similar to the brackets 230 described above (such as having a pair of flanges 334 which have apertures therein). Various means may be used to connect the cross members 222, 224, 226 to the second vertical support 310. Referring to
(21) Referring to
(22) The first vertical support 210 with integral cross members 222, 224, 226 and the separate/separable second vertical support 310 allows the end support 110 of the shelving system 100 to be collapsed or separated, thus requiring less space for packaging, storing, and shipping. Further, the end support 110 formed from the first vertical support 210 having integral cross members 222, 224, 226 and connectable second vertical support 310 maintains sufficient strength and is ease of assembly. Particularly, because the cross members 222, 224, 226 are mounted or permanently affixed to the vertical support 210, the cross members 222, 224, 226 are both securely connected to the first vertical support 210 while also being foldable or rotatable with respect to the vertical support 210.
(23) The end support 110 provides a number of advantages or prior end supports. Because the end support 110 includes foldable cross members 222, 224, 226, the end support 110 requires considerably less storage space than prior end supports. This decreases storage costs such as packing and inventory costs as well as shipping costs. The smaller packaging size may also be more convenient for an end purchaser to transport the rack 100 to an installation location. Further, because the vertical support 210 is fabricated or constructed with integral cross members 222, 224, 226, the end support 110 is easy to assemble. As described above, all the user needs to do to assemble the rack 100 is to form each end support 110 by folding out the cross members 222, 224, 226 from the first vertical support 210 and attaching them to the second vertical support 310, and then connecting the shelves 120 to the end supports 110. The assembly of the end supports 110 is obvious because the first ends of the cross members 222, 224, 226 are already mounted to the first vertical support 210, such that the free ends can only be rotated out to one position where they align with the brackets 330 of the second vertical support 310. All the user needs to do is simply pin or otherwise connect the free ends of the cross members to the second vertical support 310.
(24) At the same time, because the foldable cross members 222, 224, 226 are already installed onto the vertical support 210, they are mounted in a manner which maximizes strength while minimizing free play, thus ensuring that the end supports 110 are strong and rigid when assembled. In particular, in the preferred configuration, the brackets 230, 330 have outwardly extending spaced flanges 234. Opposing walls 236 or portions of the free ends of the cross members 222, 224, 226 are mounted to those flanges, thus reducing the play between the cross members 222, 224, 226 and the first vertical support 210 (e.g. keeping the cross members 222, 224, 226 aligned therewith). Further, unlike boltless racks of the prior art, the configuration of the invention which requires fasteners to connect the members ensures that connected members are tightly connected to one another, eliminating play between those members.
(25) The above described embodiment is an example implementation and does not limit the scope of the invention. Further modifications of the shelving unit incorporating the above features are also envisaged. For example, while the above shelving unit comprises brackets 230, 330 for connecting the cross members 222, 224, 226 to the vertical support 210, the invention is not limited to this. Instead of the bracket 230, 330, installation apertures for connecting to the cross members 222, 224, 226 may be built into the sidewalls of the channel 212 of the vertical member 210.
(26) It will also be appreciated that other forms of rotating connections might be utilized between the cross members 222, 224, 226 and the first vertical support 210. For example, the brackets 230 of the first vertical support 210 might carry bearing mounted rods to which the cross members are connected. In one embodiment, pins might actually extend through the sides of the first vertical support 210 itself (rather than through brackets 230) for rotatably mounting the cross members 222, 224, 226.
(27) The invention is not limited to the configuration of cross members 222, 224, 226 described above. For example, there may be fewer cross members (such as a single diagonal cross member, or just one or more horizontal cross members) or additional horizontal and/or diagonal cross members based on the size and strength of the desired end support. For example, an end support 110 might include a first vertical support having upper, intermediate and lower cross members which can fold for storage or extend into a generally horizontal position for connection to the second vertical support.
(28) It will also be appreciated that the mounting points for the cross members 222, 224, 226 may vary. In one embodiment, the diagonal cross member 222 might be connected to the upper bracket 230 along with the upper cross member 226, so that the diagonal cross member 222 must be rotated upwardly to connect to the second vertical support. Also, the first end of the diagonal cross member 222 need not be the same as either horizontal cross member.
(29) Further, the spacing between the brackets and/or their location (from the ends of the first vertical support 210) may vary. Also, the location of the brackets 330 of the second vertical support 310 may vary. In one embodiment, it is possible for the brackets 330 to be offset from the brackets 230 of the first vertical support 210, whereby the upper and lower cross members 224, 226 do not extend horizontally, but slope. The cross members may each be connected to a single bracket or installation aperture, or two or more cross members may be connected to a single bracket or installation aperture.
(30) While the rack 100 of the invention comprises two end supports 110 and one or more intermediate members such as shelves 120, other elements or units could be connected to or added onto the rack 100. For example, in one embodiment the rack 100 might comprise first and second end supports and one or more intermediate supports. Shelves or other elements might extend between one end support and a first intermediate support, the first intermediate support and another intermediate support, and the last intermediate support and a second end support, for example. In this regard, the end support 110 of the invention, including its method of assembly and packing, may be applied to a wide variety of products or environments.
(31) The size of the rack 100 may vary, such as depending on the desired application. As one example, the end supports 110 may be about 24 inches wide and 72 inches high and they may be spaced from one another by about 70-80 inches. As indicated however, the dimensions of the rack 100 may vary considerably.
(32) The components of the rack 100 may be constructed from a variety of materials. In a preferred embodiment, the components are constructed from metal, and preferably steel. As indicated, while the cross members 222, 224, 226 are preferably generally C shaped in cross-section so that they are strong but have a lighter weight, the cross members could have a closed hollow body construction or even be solid.
(33) It will be understood that the above described arrangements of apparatus and the method there from are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
