- Referring to the Figures, the inventive integral reinforcement kit is generally referred to as10.
Reinforcement kit 10 includes a “U”-shapedupright clamp 12 for clamping to post upright U of pallet rack P, theupright clamp 12 having anupper end 14 and alower end 16 resting on a rectangular base oranchor 18. Therectangular anchor base 18 has afront end portion 20 supportingupright clamp 12 and arear end portion 22 and defining one or more floor engagement bores to receive floor anchor bolts. - Leg support
upright tube 28 has anupper end 30 having apost support cap 32, defining a clampupper portion 33 extending toupper end 14, and alower end 34, defining a clamplower portion 35 extending toanchor base 18, resting on thefront portion 20 ofrectangular anchor base 18 and placed and sized to partially fit within the clamplower portion 35. The shortened end of pallet rack post upright U rests on thepost support cap 32, thus bearing the weight of the loaded pallet rack P. The “U”-shapedupright clamp 12 hasside walls 40 and afront wall 42 to which a front deflector 36 (preferably in the form of a right angle steel segment) extends along its substantial length, having adeflector cap 37 covering its upper end and extending downward around the base oranchor front end 20 to the floor. Thefront deflector 36 is attached to thefront wall 42 ofupright clamp 12 alongvertical attachment edges 38 near the respective edges of uprightclamp front wall 42 and extends outward from thefront wall 42, forming two equal sides, to an apex formed by a vertical corner edge spaced apart from and midway betweenattachment edges 38, bisectingfront wall 42 so as to deflect an approaching forklift tine to one side to protect the post structure. - The lower truncated end portion of post upright U is fitted within and partially surrounded by the upper portion of
upright clamp 12 to which it may be welded as shown in FIGS. 1 and 4 atweld lines 44 or attached by providingbores 46 in upright clamp side walls which receive leg support bolts through aligned bores in post upright U. Such bores are commonly provided in pallet rack posts or uprights U at spaced intervals. Leg support front wall 52 is flush to the inside of upright clampfront wall 42 and leg support side walls extend back substantially beyond the attached uprightclamp side walls 40 to end at leg supportrear wall 50. - In operation, about 6 to 12 inches of the existing post upright of the pallet rack is removed from the lower end thereof to form the truncated post upright. The inventive integral reinforcement kit, made of a substantially heavier gauge of steel than the existing post upright and pallet rack frame is then placed over the front and sides of the remaining pallet rack post or upright such that “U”-shaped
upright clamp 12 extends over and partially around the remaining lower portion of pallet rack post upright U andleg support cap 32, and leg support square upright 28 bears the weight supported by the end of the pallet rack post upright U. The assembly is then welded or bolted together to form a reinforced structure as describe above. The rectangular anchor base is then bolted to the warehouse floor. - The reinforcement kit is, for example, three inch by three inch by a quarter inch square tube welded to a quarter inch, three-sided outer clamp which in turn is welded to a two inch by two inch by quarter inch front angle deflector. These components are welded to a four inch by twelve inch by three-eighths inch footplate with two three-quarter inch by five inch by half inch wedge bolt anchors for attachment to the warehouse floor. Accordingly, this footplate replaces the original footplate. By using the reinforcement kit with the angle deflector, frontal impacts are deflected off to one side. The front post of the original pallet rack without the reinforcement features of the present kit would, over time, fail from cyclical or repeated impacts. The integral reinforcement kit of the present invention is made of any appropriate material, and preferably steel.
- It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
