Description

FIELD OF THE INVENTION

This invention relates generally to commercial and industrial storage rack systems. More particularly, the present invention relates to a new and improved method and apparatus for repairing, reinforcing and protecting damaged upright support members of typical commercial and industrial storage rack assemblies in use today.

BACKGROUND OF THE INVENTION

Forklift and other mechanical damage to the upright support members or legs of commercial and industrial warehouse-type storage racks is a major problem in the United States and in other industrialized countries. The support legs and other frame members of most commercial and industrial grade storage rack systems in use today are formed or constructed utilizing 14 to 16-gauge sheet steel. The sheet steel used to form these legs or frame members is usually cold rolled into a square shape thereby forming a structural frame member having four corners. The corners of the structural member formed in this manner give the member its strength. However, once a structural member is damaged and one or more corners of the member become bent, twisted, broken or cut, the compression strength of the member, especially members used for upright support, is severely compromised. In most cases the damaged support member cannot be effectively repaired and the member (or quite often the entire rack assembly) must be completely replaced. While the storage rack systems in use today are indeed strong and durable, the structural frame members, especially the legs or ground support members, are easily damaged by the heavy equipment typically used to load and unload product from the shelves or decking of the storage racks. The replacement or repair of damaged upright ground support members of these storage rack systems is, at best, a very labor intensive, and thus very costly, operation resulting in tens of thousands of dollars in material and repair costs every year. Presently, in order to repair or replace a damaged upright support member of a typical warehouse-type storage rack, the product being stored on the rack must first be removed from the rack shelves or decking and then stored or reshelved at another location. The rack decking and the rack beams must then be removed from the storage rack assembly for access to the damaged rack support member. Once the damaged rack support member has been repaired, or in most instances—replaced, the rack decking and the rack beams must be reassembled and the previously relocated product must then be retrieved and returned to the rack decking and placed in the proper order for inventory purposes.
It would be expedient; therefore, to provide a method and apparatus for efficiently repairing, reinforcing and protecting damaged upright support members of typical commercial and industrial storage rack assemblies wherein said assemblies do not have to be disassembled and wherein existing product being stored on said storage racks does not have to be removed and relocated in order to effectuate the repair operation.
Various devices have been proposed for protecting, replacing or repairing the frame members of warehouse-type storage racks. However, known devices, such as those disclosed in applicant's information disclosure statement submitted herewith, are not without disadvantages, disabilities, limitations and/or shortcomings which are addressed and overcome by the design, function and use of the present invention.
The present invention is a modification and significant improvement over prior art and incorporates unique, novel and cost effective design features which distinguish the invention over the existing art.

DETAILED DESCRIPTION OF THE DRAWINGS

In accordance with an embodiment of the invention, FIG. 1 shows a storage rack reinforcement and repair unit 100 designed for use in repairing, reinforcing and protecting damaged upright support members 201 of typical commercial or industrial warehouse-type storage rack assemblies 200.
The storage rack reinforcement and repair unit 100 of FIG. 1 comprises a channel member 10 having a C-shaped cross-section; said channel member 10 being attached at one end to a U-shaped base plate member 20.
As best seen in FIG. 3, the U-shaped base plate member 20 comprises a flat structural steel plate 21 having a top side 22 and a bottom or floor side 23 and having an essentially square-shaped section 24 centrally removed from said plate 21 at one edge 25.
The removal of said square-shaped section 24 from said plate 21 creates the overall U-shape of said plate member 20 and forms an internal recessed edge 26 situated between a pair of internal parallel edges 27. Said base plate member 20 having dimensions extending substantially beyond the external cross-sectional dimensions of said channel member 10. The base plate member 20 further comprises a plurality of mounting holes 28 spacably positioned along the perimeter of said plate 21 for use in attaching or securing said base plate member 20 to the floor of a warehouse building or other structure.
The C-shaped channel member 10, by definition, has three sides comprising a face panel 11 and two side panels 12 and having a top end 13 and a bottom end 14. As best seen in FIGS. 1, 3 & 5, the face panel 11 of said channel member 10 further comprises a plurality of strategically placed, and precisely spaced, attachment holes 15 along the length of said channel member 10. Said attachment holes 15 are designed for aligning with, and for engagement of, the pre-stamped adjustment holes 202 of a rack support member 201 during the installation of the storage rack reinforcement and repair unit 100. As best viewed in FIG. 3, the bottom end 14 of said channel member 10 is rigidly attached, as by welding, to the top side 22 of the steel plate 21 of said U-shaped base plate member 20 along the internal recessed edge 26 and along a portion of the internal parallel edges 27 of said steel plate 21 as shown so as to cause said channel member 10 to extend perpendicularly and vertically from said base plate member 20. The internal cross-sectional dimensions of the channel member 10 are designed to align with the dimensions of the recessed edge 26 and the parallel edges 27 of said steel plate 21 as shown. As best seen in FIGS. 4 & 5, the internal cross-sectional dimensions of the channel member 10 and the dimensions of the square-shaped section 24 of the U-shaped plate member 20 are designed to wrap around and nestably accommodate the external cross-sectional dimensions of said storage rack support member 201.
In order to use the invention to repair, reinforce and protect the damaged support member 201 of a typical storage rack assembly 200, the storage rack reinforcement and repair unit 100 thus formed is first bolted to the floor utilizing the mounting holes 28 of said of said base plate member 20. The unit 100 is bolted to the floor at the precise location occupied by, or previously occupied by, said damaged storage rack support member 201. Once the unit 100 has been firmly bolted to the floor, the channel member 10 of said unit 100 is then used to leverage the damaged support member 201 into alignment with said channel member 10 and thereby cause said support member 201 to nestably engage the side panels 12 and face panel 11 of said channel member 10. Once the damaged support member 201 is properly aligned with, and engaged by, the channel member 10 and base plate member 20 of said unit 100, the support member 201 is then bolted to said channel member 10 utilizing the attachment holes 15 situated along the face panel 11 of said channel member 10.
While the invention has been particularly shown and described with reference to the preferred embodiment thereof, it will be understood by those skilled in the art that various alterations in form, detail and construction may be made therein without departing from the spirit and scope of the invention.
