Description
- The present invention relates to a pallet rack structure and more particularly, relates to an adjustable brace suitable for use in repairing a pallet rack structure.
- Pallet racks are well known and are widely used in warehouses wherein typically they extend in a plurality of rows for substantially the height of the building with space being provided between the rows for fork lift trucks to operate. The fork lift trucks will remove pallets from the shelves as required for the shipping of the product thereon and/or for further processing.
- More recently, the trend has been to open large warehouse or “big box” stores to the public. In such stores, pallet racks are used to display the merchandise.
- Inherently, there are dangers in such a system and safeguards against collapse must be provided. Numerous accidents have occurred over the years and injuries and death have occurred as a result of the collapse of the pallet racks.
- To date, most of the safety concerns have centered around the various design criteria to ensure that the pallet racks are capable of accepting the loads to which they are subjected. The conventional pallet rack is of a knock down design wherein the vertical posts are provided with horizontal beams which are secured to the posts. Diagonal bracing extending between posts may then be provided to further ensure a rigid structure.
- While the engineering of the pallet racks provides sufficient safety for normal use, the racks are very susceptible to damage. Inherently, the loaded pallets must be lifted onto the racks by fork lift trucks. Due to the often limited spaces, an accident wherein the fork lift truck will collide with one of the vertical posts occurs sufficiently frequently. With the very high loads which the pallet racks carry, this is a dangerous situation and any post even slightly damaged has to be replaced.
- In order to replace a damaged post, the load of pallets must be removed from the structure and the rack disassembled. After new rack components are installed, the pallets must be reloaded on the structure. As will readily be understood, this is both an extensive and time consuming process.
- It has been suggested in the art that pallet rack repair systems can be provided and which systems overcome the above disadvantages. An example of such a system is shown in Canadian Patents 2,232,178 and 2,280,645.
- While the above mentioned pallet repair systems function very well, frequently there is a need to replace a diagonal brace which extends between two levels of the pallet. However, to merely provide a conventional diagonal brace which is secured to the vertical posts does not necessarily add sufficient rigidity to the structure.
- Accordingly, it is an object of the present invention to provide a diagonal brace for use in the repair of pallet rack structures.
- According to one aspect of the present invention, there is provided in a pallet rack structure comprising four corner posts, a plurality of beams extending between the corner posts, a plurality of diagonal braces extending between the corner posts, the improvement comprising at least one of the diagonal braces extending between first and second corner posts, the diagonal brace having first and second members, the first and second members being telescopically arranged, means for securing the first and second members together in a fixed position, a first bracket mounted on the first post, and a second bracket mounted on the second post, the arrangement being such that an extended longitudinal center line of the brace passes through, at each end, a point of joinder of a post and a beam.
- According to a further aspect of the present invention, in a pallet rack structure comprising four corner posts, a plurality of beams extending between the corner posts, there is provided a plurality of diagonal braces extending between the corner posts, the improvement comprising at least one of the diagonal braces extending between first and second corner posts, the diagonal brace having first and second members, the first and second members being telescopically arranged, means for securing the first and second members together in a fixed position, a first bracket mounted on a beam, and a second bracket mounted on a post, the arrangement being such that an extended longitudinal center line of the brace passes through, at each end, at a point of joinder between post and a beam.
- According to a still further aspect of the present invention, there is provided in a method of repairing a pallet rack structure wherein a reinforced base portion is installed on the pallet rack structure, the improvement comprising the step of replacing a diagonal brace above the reinforced base portion, including the steps of attaching a first bracket to one of a horizontal beam or a vertical post, attaching a second bracket to a vertical post, securing a telescopic brace to the first and second brackets, the arrangement being such that an extended longitudinal center line of the brace passes through, at each end, a point of joinder between a post and a beam.
- The improvements of the present invention are designed to be used in the repair of pallet racks. As aforementioned, such pallet rack repair systems are shown in Canadian Patents 2,280,645 and 2,232,178, the teachings of which are hereby incorporated by reference.
- In the prior art patents, typically a portion of a front and optionally a rear post are replaced depending upon the damage and the desired results. The present invention is designed to be used to replace the diagonal brace immediately above the repaired section. In this arrangement, there is always a horizontal beam which is replaced.
- According to the present invention, the diagonal brace is arranged such that an extended longitudinal center line of the brace passes through a point of joinder of a post and beam. This occurs at both the upper and lower extremities of the brace.
- The lower end of the brace may be secured either to a post or alternatively, to a beam. In either case, the arrangement of the bracket is such that the extended longitudinal center line of the brace extends through the point of joinder of the beam and post.
- In the case of the upper bracket, it is always secured to the post.
- Having thus generally described the invention, reference will now be made to the drawings illustrating embodiments thereof, in which:
-
FIG. 1 is a perspective view of a replacement brace according to the present invention; -
FIG. 2 is an end elevational view of a portion of a pallet rack utilising the replacement brace of the present invention; -
