FIGS. 1-6 illustrate a swing-out wall rack 10 configured to be coupled to a wall 12. The swing out wall rack 10 can include a frame 14 and a rack 16. The frame 14 can include a vertical member 18, a first horizontal arm 20, and a second horizontal arm 22. The vertical member 18 can be configured to be coupled to a wall 12 or other feature. For example, the vertical member 18 can include several fastener openings 24 through which fasteners (not shown) can couple the frame 14 to the wall 12. As shown in FIG. 1, the first horizontal arm 20 can be spaced apart from the second horizontal arm 22 and substantially parallel to the second horizontal arm 22. The first horizontal arm 20 can include a proximal end 26 and a distal end 28. Similarly, the second horizontal arm 22 can include a proximal end 30 and a distal end 32. The proximal ends 26, 30 can be coupled to the vertical member 18.
As illustrated in FIGS. 1-3, the rack 16 can include a top side 34, a bottom side 36, a first side 38, and a second side 40. The second side 40 can be opposite from the first side 38. The distance between the top side 34 and the bottom side 36 can define a height of the rack 16 and the distance between the first side 38 and the second side 40 can define a width of the rack 16. The rack 16 can provide mounting locations for electronic equipment (not shown).
The rack 16 can be coupled to the frame 14. In the embodiment shown in FIGS. 1-3, the rack 16 is coupled to the first horizontal arm 20 and the second horizontal arm 22. The top side 34 of the rack 16 can receive a fastener 42 to couple to the distal end 28 of the first horizontal arm 20. The bottom side 36 of the rack 16 can receive a fastener 42 to couple to the distal end 32 of the second horizontal arm 22. It is contemplated that the rack 16 need not be coupled to both the first horizontal arm 20 and the second horizontal arm 22. Additionally, it is also contemplated that the rack 16 could be modified to be coupled to the frame 14 at the first side 38 and/or the second side 40.
The rack 16 can include a mid-point 44 that is equidistant from the first side 38 and the second side 40. The mid-point 44 can be located on the top side 34 and/or bottom side 36. The mid-point 44 can define the point at which the rack 16 is rotatably coupled to the frame 14. As shown in FIGS. 1-3, the rack 16 can rotate about the mid-point 44 in either a clock-wise or counter-clockwise direction. Advantageously, rotating the rack 16 about the midpoint 44 allows equal access to any side 34, 36, 38, 40 of the rack 16. As shown in FIGS. 1-3, the first horizontal arm 20 and the second horizontal arm 22 are long enough such that the rack 16 can rotate about the first horizontal arm 20 and the second horizontal arm 22 at the distal ends 28, 32 a full 360° with respect to the frame 14.
As best shown in FIGS. 4-6, the swing-out wall rack 10 can also include a locking pin 45. The locking pin 45 allows the rack 16 to be locked in multiple rotatable orientations with respect to the frame 14. The locking pin 45 can pass through a clearance hole 46 in the first horizontal aim 20 of the frame 14. The top side 34 of the rack 16 can include a plurality of locking holes 48 configured in an annular path 50. The clearance hole 46 and the locking pin 45 can be located along the annular path 50 such that as the rack 16 rotates with respect to the frame 14, the locking pin 45 selectively engage one of the plurality of locking holes 48 to lock the rack 16 with respect to the frame 14.
As shown in FIG. 6, the locking pin 45 can include a detent 52 as is known in the art that can engage the selected locking hole 48 when the locking pin 45 is released by the user. To unlock the swing-out wall rack 10, the user merely pulls up on the locking pin 45 to release the detent 52 and engagement between the locking pin 45 and the selected locking hole 48, allowing the rack 16 to be rotated again with respect to the frame 14. Although there are eight locking holes 48 arranged in the annular path 50 in the top side 34 of the rack 16, it is contemplated that other amounts of locking holes 48 could be used. Furthermore, it is contemplated that other sides 36, 38, 40 of the rack 16 can include locking holes 48 depending on the orientation and desired rotation of the rack 16 with respect to the frame 14. For example, the embodiment shown in FIGS. 1-6 has locking holes 48 configured in an annular path 50 on the bottom side 36 of the rack 16. If desired, more than one locking pin 45 could be used with the swing-out wall rack 10.
The swing-out wall rack 10 can also include a mounting hook 54. The mounting hook 54 can allow a single user to couple the frame 14 to the wall. As illustrated in FIGS. 2 and 3, the mounting hook 54 can include a hook portion 56 and a mounting portion 58. The mounting portion 58 can include mounting holes 60 to fasten the mounting hook 54 to the wall 12. Thus, before installing the swing-out wall rack 10 to the wall 12, the user can fasten the mounting hook 54 to the wall 12.
The frame 14 of the swing-out wall rack 10 can include a mounting passage 62 to engage the mounting hook 54. The mounting passage 62 can be located on the vertical member 18 of the frame 14. Once the mounting hook 54 is coupled to the wall 12, the user can mount the frame 14 of the swing-out wall rack 10 on the mounting hook 54 by inserting the hook portion 56 through the mounting passage 62. The user can level the frame 14 of the swing out wall rack 10 and couple the frame 14 to the wall 12 with fasteners through the fastener openings 24. Thus, a user can single handedly mount the frame 14 and rack 16 of the swing-out wall rack 10 to the wall 12 by themselves with the use of the mounting hook 54.
FIGS. 7 and 8 illustrate a second embodiment of a swing-out wall rack 110. The swing-out wall rack 110 is generally constructed the same as the swing-out wall rack 10 described above, so only the differences in the swing-out wall rack 110 will be explained. The swing-out wall rack can include a frame 114, a rack 116, a vertical member 118, a first horizontal arm 120, and a second horizontal arm 122. The rack 116 can be rotatably coupled to the first horizontal member 120 and the second horizontal member with fasteners 142 about a mid-point 144 of the rack 116. The rack 116 is coupled to first horizontal arm 120 substantially near a mid-point 164 between the proximal end 126 and the distal end 128 of the first horizontal arm 120. Similarly, the rack 116 is coupled to the second horizontal arm 122 substantially near a mid-point 164 between the proximal end 130 and the distal end 132 of the second horizontal arm 122. As shown in FIG. 8, such a coupling of the rack 116 and frame 114 allows the rack 116 to be rotated approximately 90° with respect to the frame 114 into a compact size. For example, the first side 138 of the rack does not extend beyond the distal ends 128, 132 of the first and second horizontal arms 120, 122. Additionally, the swing-out wall rack 110 can be completely assembled when shipped, reducing the time for installation at the desired location. The rack 116 can also be locked in more than one rotatable orientation with respect to the frame, as discussed above with respect to swing-out wall rack 10, by including a locking pin 145 and associated locking holes 148. The swing-out wall rack 110 can also include a mounting hook 154. The mounting hook 154 can include a hook portion and a mounting portion.
The center pivot swing-out wall rack 10, 110 provides several advantages due to its center pivot structure. For example, by rotatably coupling the rack 16, 116 to the frame 14, 114 substantially about a mid-point 44, 144 of the rack 16, 116, the moment arm on the rack 16, 116 generated from the weight of electronic equipment (not shown) attached to the rack 16, 116 can be virtually eliminated. Additionally, the moment arm on the first and second horizontal arms 20, 120, 22, 122 can also virtually be eliminated for the same principle. Furthermore, the first and second horizontal arms 20, 120, 22, 122 can each carry a portion of the weight of the electronic equipment (not shown) on the racks 16, 116.
FIGS. 9A, 9B, 10A, and 10B illustrate a third embodiment of a swing-out wall rack 210. The swing-out wall rack 210 is generally constructed the same as the swing-out wall rack 10 described above, so only the differences in the swing-out wall rack 210 will be explained. The swing-out wall rack can include a frame 214, a rack 216, a vertical member 218, a first horizontal fixed arm 220, a first horizontal telescoping arm 221, a second horizontal fixed arm 222, and a second horizontal telescoping arm 223. The horizontal fixed arms 220, 222 and the horizontal telescoping arms 221, 223 cooperate as nested telescoping arms which allow for movement of the telescoping arms 221, 223 in the horizontal direction. The rack 216 can be rotatably coupled to the first horizontal telescoping arm 221 and the second horizontal telescoping arm 223 with fasteners 242. The top side 234 of the rack 216 can receive a fastener 242 to couple to the distal end 228 of the first horizontal telescoping arm 221. The bottom side 236 of the rack 216 can receive a fastener 242 to couple to the distal end 232 of the second horizontal arm 222. It is contemplated that the rack 216 need not be coupled to both the first horizontal telescoping arm 221 and the second horizontal telescoping arm 223. Additionally, it is also contemplated that the rack 216 could be modified to be coupled to the frame 214 at the first side 238 and/or the second side 240.
Electronic equipment (not shown) can be coupled to the rack 216 as is known in the art. Cables (not shown) connecting to the electronic equipment on the rack 216 can be managed via openings or cutouts 260 in the first horizontal fixed arm 220, the first horizontal telescoping arm 221, the second horizontal fixed arm 222, and/or the second horizontal telescoping arm 223. These cutouts 260 are pass-through openings for electrical cables or wires when are then run within the arms 220, 221, 222, 223 as needed for cable management. There can be one or more cutouts 260 in each of the arms 220, 221, 222, 223. Further, the cutouts 260 in the telescoping arms 221, 223 are substantially the same size as corresponding openings in the fixed arms 220, 222 to allow the cutouts 260 in the respective arms 220, 221, 222, 223 to align and allow for cables to pass through. FIGS. 9A and 9B show a perspective view and top view respectively of this embodiment of the swing-out wall rack where the telescoping arms 221, 223 are in a retracted position with respect to the fixed horizontal arms 220, 222. FIGS. 10A and 10B show a perspective view and top view respectively of this embodiment of the swing-out wall rack where the telescoping arms 221, 223 are in an extended position with respect to the fixed horizontal arms 220, 222.
The center pivot swing-out wall rack 210 provides several advantages due to its cable management system. For example, having the cable management in the center of the rack 210 rather than running the wiring along the side of the rack 210 provides an advantage for organization of the wiring. Also, there are no additional parts or accessories needed for cable management because the interior space of the arms 220, 221, 222, 223 is used. Further, in an embodiment where the frame 214 can be telescoping, a user can have infinite adjustment of where the rack 216 is rotatably coupled to the frame 214. While the above description and FIGS. 9A, 9B, 10A and 10B show an embodiment including both the telescoping arm feature and the cable management feature, it is understood that either one or both of these features can be implemented in a single embodiment of the center pivot swing-out wall rack.
It will be appreciated by those skilled in the art that while the invention has been described above in connection with particular embodiments and examples, the invention is not necessarily so limited, and that numerous other embodiments, examples, uses, modifications and departures from the embodiments, examples and uses are intended to be encompassed by the claims attached hereto.
