The present disclosure relates to devices for anchoring stationary equipment.
This section provides background information related to the present disclosure which is not necessarily prior art.
In areas of moderate to high seismic activity, the Uniform Building Code requires anchoring, or stabilization, for storage racks, cabinets, shelving systems, and other various stationary equipment, so as to prevent these systems from becoming moving hazards in an earthquake. Seismic anchoring is designed and constructed to anchor, or restrain, the rack, cabinet, shelf, etc., in such a manner as to resist stresses and limit deflections caused by earthquake forces.
Existing seismic anchoring systems require leveling of the unit and then cross drilling the shelving posts in the field and using clevis pins to secure the post to the baseplate. Also, different baseplates are provided to accommodate different diameter or shapes of posts.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
An anchoring system may include a mount having a base and a socket. The socket may be fixed to the base. A leveler may be positioned within the socket and may be configured to be adjustably engaged to one of a plurality of posts of a shelving system. A fastener may secure the leveler to the socket. The leveler may be adjusted to change the height of the post in relation to other of the plurality of posts in the shelving system, and thereby level the shelving system.
Another anchoring system may include a mount having a base and a socket. The mount may be fixed to an immovable structure. The socket may be fixed to the base and may include a first bore and a second bore spaced symmetrically apart on the socket. A leveler may have a head, a threaded portion, and a spacer. The head may be positioned within the socket and may further include a third bore extending through the head. The threaded portion may be configured to be adjustably engaged to and received within a bore of one of a plurality of posts of a shelving system. The spacer may maintain a distance between the one of the plurality of posts and the head. A fastener may have a rod and a clip. The rod may pass through the first, second, and third bores to retain the leveler in the position within the socket, and the rod may receive the clip to retain the rod within the first, second, and third bores. The leveler may be rotated clockwise or counterclockwise to adjust the location of the threaded portion within the post and thereby adjust the height of the post in relation to others of the plurality of posts to level the shelving system. The mount may be configured to be used in a seismic anchoring system to secure the shelving system to the immovable structure, especially during seismic activity.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
The anchoring system described herein may be used for anchoring stationary equipment, such as shelving units. While shelving units are described throughout the detailed description, one of ordinary skill in the art understands that any stationary equipment may be secured using the presently described anchoring system. The baseplate and anchoring system described herein eliminates the need for in-field drilling as required by current seismic anchoring systems. Since, in current systems, the leveling of the unit must be performed before cross drilling the shelving posts, both leveling and drilling must be performed in the field. In the disclosure herein, the baseplate removes the need for in-field drilling, and requires only the leveling to be performed in the field, reducing the time for installation, the cost, and the difficulty of installation.
Further, the baseplate and anchoring system described herein also allows one baseplate to be used for any size or shape of post, reducing the number of SKUs associated with the baseplates and the cost of production.

The socket 18 may further include a plurality of slots, or bores, 26 for receiving a fastener 30, such as a clevis pin (
The socket 18 may be a 1.25 in., schedule 40 (SCH 40) pipe socket that is fixed on a first end 46 to the plate 14. A second end 50 may be a distance L1 from the first end 46, giving the socket 18 a length L1. The length L1 may be sized according to the project. For example only, the socket 18 may be a length L1 of 0.84 in.
The slots 26 may be a height H1 and may be positioned in a center of the socket 18 with a distance L2 on each side. The slots 26 may be determined based on the diameter of the clevis pin 30. For example only, for a 5/16 in. clevis pin, the slots 26 may have a height H1 of 0.34 in. The distance L2 on each side of the slots 26 is determined based on the length L1 of the socket 18 and the height H1 of the slots 26. For example only, the distance L2 on each side of the slots 26 may be 0.25 in.
The slots 26 may also have a length L3. The length L3 of the slots 26 may also be determined based on the diameter of the clevis pin 30. For example only, for a 5/16 in. clevis pin, the length L3 of the slots 26 may be 0.70 in. The length L3 of the slots 26 allows for tolerances and minor misalignment between the shelving and the anchored plates 14 during assembly. Often, when anchoring or mounting shelving, the post 90 may not line up perfectly concentric with the socket 18 after the plate 14 is anchored to the floor, wall, etc., and the tolerances allow for this minor misalignment.
The socket 18 may be formed of a material similar to the plate 14, such as steel, and may be fixedly engaged, such as through welding, to the plate 14. A weld 54 may extend around an outer wall 58 of the socket 18 at the intersection of the socket 18 and the plate 14. The weld 54 may be a fillet weld having a cross-section w and length L4. The cross-section w and length L4 may be adjusted based on the material of the plate 14 and socket 18, forces acting on the socket 18, and a circumference of the outer wall 58 of the socket 18. For example only, the cross-section w may be ⅛ in., and the length L4 may be within a range of 1.25-2.625 in.
Now referring to
A width W1 of the leveler 62 may be sized to fit within the socket 18 and such that the leveler 62 may be adjusted with a wrench during installation. For example only, the width W1 of the leveler 62 may be ⅞ in. such that the leveler 62 may be adjusted during installation with a ⅞ in. wrench.
The head 66 may have a height H2. The height H2 may be determined based on the length L1 of the socket 18. For example, if the length L1 of the socket 18 is 0.84 in., the height H2 of the head 66 may be 1.22 in., so that the head 66 extends 0.375 in. (⅜in.) above the second end 50 of the socket 18. The 0.375 in. extension above the second end 50 of the socket 18 allows enough clearance for the head 66 to be adjusted using a wrench after installation within the socket 18.
The spacer 70 may be a cylindrical portion and may be formed from a similar material as the head 66, such as a metal or steel. The spacer 70 is fixedly engaged to the head 66, for example, by welding. The spacer 70 may have a smooth surface 82 and a diameter D2 that is less than the width W1 of the head 66. For example only, the diameter D2 may be ⅜ in. The spacer 70 may function to provide a predetermined amount of space between a foot 86 of a post 90 (
The spacer 70 may include a first end 98 and a second end 102 opposite the first end 98. The spacer 70 may include a height H3 extending from the first end 98 to the second end 102, and the height H3 may be determined based on a desired amount of space between the foot 86 of the post 90 and the top 94 of the head 66. For example only, the height H3 may be 0.62 in. The spacer 70 may be positioned in the leveler 62 between the head 66 and the threaded portion 74, such that the first end 98 is engaged to the top 94 of the head 66 and the second end 102 is engaged to a first end 106 of the threaded portion 74.
The threaded portion 74 may be a cylindrical portion and may be formed from a similar material as the head 66 and the spacer 70, such as metal or steel. The threaded portion 74 is fixedly engaged to the spacer 70, or a portion of the spacer 70. A diameter D3 of the threaded portion 74 is approximately or generally the same as diameter D2 of the spacer 70 and less than width W1. For example only, the diameter D3 may be ⅜ in.
The threaded portion 74 further includes threads 110. The threaded portion 74 may receive the post 90 (
The threaded portion 74 may include a height H4 extending from the first end 106 to a second end 114. The height H4 may be determined based on the length of a threaded portion of the post 90. For example only, the height H4 may be 0.56 in.
An overall height H5 of the leveler 62 may be equivalent to the sum of the individual heights H2, H3, and H4. For example only, the overall height H5 may be 2.40 in.
Now referring to
As assembled, the head 66 of the leveler 62 extends a predetermined length above the socket 18 such that the head can be adjusted with a wrench during installation. For example only, as previously discussed, the head 66 may extend 0.375 in. (⅜ in.) above the second end 50 of the socket 18. The head 66 of the leveler 62 may be adjusted to level the post 90 in relation to the plate 14 and floor or wall. A wrench (for example, a ⅞ in. wrench) may be used to adjust the head 66 before the clevis pin 30 is inserted through the bores 26 and 78. For example only, the adjustment may be 1/31 in. (a result of 180° rotation and 16 threads per inch thread).
The post 90 may include an interior bore 118 extending a depth D1 along an axis Y longitudinally down the length of the post 90. The interior bore 118 may have a diameter D4 equal to, or slightly greater than, the diameters D2 and D3 such that the threaded portion 74 and spacer 70 may be received within the interior bore 118. For example only, the diameter D4 may be ⅜ in. The interior bore 118 may include threads (not illustrated) that mate with the threaded portion 74 of the leveler 62 and retain the post 90 on the leveler 62. The threads (not illustrated) of the interior bore 118 may be designed to mate with the threads 110 of the threaded portion 74. For example only, the threads of the interior bore 118 may be ⅜-16 threads.
When assembled, the foot 86 of the post 90 may be kept a minimum distance from the top 94 of the head 66 depending on the height H3 of the spacer 70, the height H4 of the threaded portion 74, and the depth D1 of the bore 118. For example only, if the height H3 is 0.62 in, and the height H4 is 0.56 in., the depth D1 may be 0.97 in. to leave a minimum distance of 0.21 in. between the post 90 and the top 94 of the head 66.
After assembly of the post 90 to the leveler 62 and the leveler 62 to the plate 14, the post 90 may be leveled by rotating head 66 of the leveler 62 clockwise or counterclockwise (for example, using the ⅞ in. wrench) to adjust the position of the threaded portion 74 within the bore 118. Once all posts 90 and seismic baseplates 10 have been assembled and leveled, the clevis pin 30 may be inserted in the bores 26 and 78 of each seismic baseplate 10.
While the post 90 is illustrated as a cylindrical post, it will be understood to those skilled in the art that the post 90 may be any size or shape of post, such as cylindrical, triangular, hexagonal, or any other size or shape. The post 90 may also be of any material, such as metal or plastic.
In an alternate embodiment, the threaded portion within the bore 118 of the post 90 may be provided by a threaded accessory 122 positioned on the foot 86 of the post 90 as illustrated in
The base 138 of the portion 126 further includes a through-bore 154 extending from a top 158 to a bottom 162 and being sized to receive the threaded portion 74 of the leveler 62. For example only, the through-bore 154 may have a diameter of approximately ⅜ in. An interior wall 166 of the through-bore 154 may include a threaded portion 170 that engages with the threaded portion 74 of the leveler 62 similarly to the method previously described in relation to other embodiments. For example only, the threaded portion 170 may include ⅜-16 threads, to mate with the threads 110 of the threaded portion 74.
The post 90 may further include a groove 174 around a circumference of the post 90 that engages with the ridge 146 when the threaded accessory 122 is positioned on the post 90 to locate the threaded accessory 122 on the post 90. The portions 126, 130 may clamp together around the post 90 to secure the portions 126, 130 to the post 90. When the portions 126, 130 are clamped around the post 90, the foot 86 of the post 90 may mate with the top 158 of the base 138. Thus, by using the threaded accessory 122, different sided and shaped posts may be fitted with the threaded accessory 122 and used with the same leveler 62.
