Definitions

  • the invention relates to adjustable beam type storage racks having posts or columns between which the beams extend, the beams being mountable in any of various vertically spaced positions, and when mounted, being wedged tightly against the columns by inter-engaging surfaces on the columns and beam ends.
  • racks are used in industrial plants and are normally loaded by means of fork lift trucks which often strike the lower ends of the columns, denting and therefore weakening them. Since the lower ends carry the maximum load, the aforesaid weakening could necessitate replacement of the columns if danger of collapse exists.
  • the present invention is an improvment on the adjustable storage rack construction shown in Patent No. 3,044,- 633, issued July 17, 1962 to E. A. Baker, Jr., et al.
  • the construction shown in this patent sulfers from the aforesaid disadvantage, and it is an object of the present invention to provide a storage rack of this type in which the columns can be reversed when the lower ends are dented, so that the upper ends, which are still intact, can bear the heavier load and the wedging and other advantages of the construction will still be preserved.
  • the side walls of the pressed-out slots in the columns are provided with flares which extend in opposite directions, so that the teeth of the connecting members at the ends of the beams can be inserted in these slots in either direction and still obtain the wedging action.
  • the slots are symmetrical about a horizontal axis.
  • FIGURE 1 is a front elevational view of a section of an adjustable storage rack incorporating the construction of this invention
  • the adjustable storage rack is generally indicated at 11 and comprises a plurality of pairs of front and rear posts or columns 12 and 13. Each pair of columns is connected by horizontal members 14 and diagonal braces 15. Each pair of adjacent front or rear columns is adapted to receive the L-shaped end connecting members 16 of a load carrying beam 17.
  • the end connecting members 16 are mounted on the posts by means of a plurality of pressed-out slots 18 in vertically spaced relation on each column, which is of box-shaped cross section with a partially open side opposite the slots. These slots receive teeth 19 on end connecting members 16, as seen in FIG- URE 4. There are three teeth formed on each connecting member, these teeth being spaced apart the same distance as slots 18, which are formed in the central web 20 of each column.
  • the slots are open in both upward and downward directions and have side walls 21 which have a double flare. More particularly, the side walls 21 of each slot 18 are symmetrical about a horizontal axis and are flared in such a manner that when teeth 19 enter the slots, the surfaces 22 (FIGURE 4) of connecting member 16 will be tightly wedged against the adjacent side wall 23 of column 12 or 13.
  • FIGURE 3 shows in solid lines a connecting member 16 which enters slots 18 in one direction and in phantom lines another connecting member 16 entering the slots from the opposite direction.
  • the column 12 will be inverted when it is desired to place a connecting member 16 in the slots as shown in the phantom lines. This will be done when the lower end of a particular column becomes dented and thereby weakened, usually for the aforesaid reason.
  • slots 18 are wide enough to receive connecting members 16 from opposite sides so that beams 17 may be mounted in adjacent sections of the storage rack, as shown in FIGURE 1.
  • the drawing also has a partial showing of safety locking tabs 24 which are the subject of a separate copending application.
  • an adjustable storage rack of the type having spaced columns of generally polygonal cross section each with a central web and side walls, and beams extending between said columns and secured thereto by connecting members having teeth which enter slots in said central webs
  • the slot construction comprising a plurality of vertically spaced pressed-out channels forming slots in said central webs and which channels open upwardly and downwardly along an axis substantially parallel to the column, and side walls on each of said channels, at least one of the opposed side walls at each end of the channels diverging upwardly and downwardly respectively from the central portions thereof, whereby the connecting memher teeth entering said slots in either direction will be wedged tightly against a side wall of said column.
