Definitions

  • This invention relates to the art of support structures, particularly to a collapsible shelf structure adapted for supporting palletized loads, of a type commonly referred to as a pallet rack.
  • pallets or skids as supports for loads of all varieties of materials has been on the increase in recent years.
  • the skid or pallet not only supports the load, but it permits the forks of a lift truck to be inserted below it in order to allow the palletized load to be conveniently transported from place to place as required. Due to the increased use of palletized loads, a definite need arose for a supporting structure which can support a maximum number of palletized loads in a minimum space at a minimum cost.
  • Structures for this purpose have been developed. They are generally in the form of vertical upright members joined together by horizontal side to side and front to back members which form an open type skeletal structure.
  • the vertical members are made long enough to support the horizontal members at vertically spaced intervals to provide a multi-t-iered structure for supporting palletized loads at different stacked levels.
  • the vertical members are spaced horizontally from each other by calculated amounts to establish bays of given length to accommodate a given number of palletized loads in a row without waste of space on the pallet rack structure.
  • the structures can be made of any length and any height depending upon the particular storage space available.
  • Another desirable feature is to have a minimum of parts and, if possible, no extra detachable parts which can be misplaced, such as connector pins.
  • Another desirable objective is to have maximum load bearing support between the structural members in different contact planes with means to resist beam rotation, if possible.
  • a pallet rack structure wherein there are only two basic components, the vertical supports or uprights and horizontal beams. These are no other separate parts which can be detached and misplaced.
  • the connections between the uprights and the beams are by flanged lugs projecti g from flanged ends of the beams where they can be easily engaged in slanted key hole slots in the uprights and wedged into tight engagement therewith.
  • the flanges on the beam ends are bent at right angles so that they make contact with the uprights along two difierent planes.
  • a very significant feature is a releasable bolt or latch at each end of the beams which is engaged with the upright to provide a safety means for preventing accidental removal of the beams once in place and which provides additional bearing support in a plane different than the principal plane of bearing support by the flanged lugs on the beams.
  • the bolt by providing a bearing support in this additional plane, also provides means for resisting rotation of the beams in place.
  • FIG. 1 shows a perspective view of a partially cutaway pallet rack structure embodying the features of this invention
  • FIG. 2 shows a partially cutaway and enlarged sectional view of a portion of the pallet rack structure of FIG. 1 showing the region of connection between the end of a beam and an upright member;
  • FIG. 3 shows a partially cutaway and sectional elevation view of a beam connected to an upright
  • FIG. 4 shows a sectional view along the line 4-4 of FIG. 3;
  • FIG. 5 shows a view along the line 5-5 of FIG. 3;
  • PEG. 6 shows an enlarged sectional view along the line 6-6 of PEG. 3 and particularly shows the shape of one of the flanged connector lugs;
  • H6. 7 shows a sectional view along the line 7-7 of
  • a typical support structure or pallet rack 1 consists of a pair of ladder-shaped upright frames 2 and 3 spaced apart from each other and joined together by means of horizontal beams 4, 5, 6 and 7. These beams are joined at their ends to the upright frames 2 and 3 in a manner hereinafter described.
  • the upright frame 2 is also joined to the ends of other horizontal beams 8, 9, it) and 11 which, although not shown, extend to an additional spaced upright frame similar to frames 2 and 3. In this manner the entire pallet rack 1 can be made any length required.
  • the beams 8, 9, 1t) and 11 extend from the frame 2, other beams can extend in the opposite direction from the frame 3 so that the pallet rack can be extended in length in either direction.
  • Each of the upright frames 2 and 3 consists of a front upright 12 and a rear upright 13 joined together by horizontal front to back members 14- and 15 and diagonal braces 16 and 17.
  • the lengths of the members 14, l5, l6 and 17 can be appropriately cut to space the uprights 12 and 13 as far apart as necessary to provide the proper span between the front beams 4 and 5 and the rear beams 6 and '7.
  • the uprights 12 and 13 can be made as tall as necessary in order to accommodate the required vertical spacing of the horizontal beams, as well as to permit positioning of as many vertically spaced beams as desired.
  • additional members similar to 14-, 15', 16 and 17 can be added to provide sufiicient rigidity and strength.
  • the beams 5 and a provide a span across which pallets or other articles can span so that the beams act as their support at an upper level.
  • the beams 4. and 7 provide a spanned support for pallets or other objects at a lower level.
  • a pallet 18- is shown supported by the beams 4 and 7 and also a board 19*. If continuous shelving is required so that objects will not fall through the spanned opening between the beams, a plurality of boards 19 can be positioned side by side along the beams to provide a continuous uninterrupted support for various shapes and sizes of objects.
  • the front to back members 14 and 15 and diagonal braces 16 and 17 are preferably welded at their ends to the uprights l2 and 13 in order to provide the completed ladder-shaped upright frames 2 and 3. This enables the frames 2 and 3 to be shipped as integral units, thus saving erection time and also insuring a rigid structure which might not be obtained if nuts and bolts or other fastening means are used to secure these members together.
  • Each of the uprights 12 and 13 is provided with two rows of first openings 2d extending along the entire length of the front walls 21 of the uprights. The openings are equally spaced from each other by a fixed increment.
  • Each of the uprights 12 and 13 is also provided with a row of equally spaced openings 22 along opposite side walls 23 and 24 of the uprights. These side walls 23 and 24 are positioned parallel to each other and are connected therebetween by the front wall 21 which forms the upright into a channel shape.
  • the side Walls 23 and 24 are provided with flanges 25 and 26 which extend toward each other in a plane parallel to the front wall 21 of the upright.
  • the flanges 25 and 25, the side walls 23 and 24 and the front wall 21 together provide a flanged channel-shaped upright with four corners 27, 28, 29 and 31 which impart column strength and rigidity to the up rights.
  • a horizontal beam 6 consists of an L-shaped tube 31 composed of two channels 32 and '33 facing each other with their flanges 32a, 32b and 33a, 331:, respectively, overlapping each other to form a closed tube (FIG. 4).
  • the overlapping flanges 32a, 32b, 33a and 33b are preferably welded together to maintain the channels 32 and 33 joined together and to impart strength to the assembled tube.
  • This tube 31 is welded at each of its ends to one wall 34 of an L-shaped end flange 35.
  • the other wall 36 of the end flange 35 is provided with two inwardly extending flanged lugs 37 which are in fixed positions on the end flange 35.
  • each of these flanged lugs 37 is provided with a cylindrical body portion 37a having two flats 3715.
  • a hole 38 is provided in the wall 36 of the end flange which is of the same shape as the body portion of the flanged lug in the region of the flats 37b. The reason for this particular shape of the body portion of each of the lugs 37 is to prevent rotation of the lug after it is once in place. When in place, the lug bottoms in the opening 38 against shoulders 37c produced by the cutout of the flats 37b. With the lugs 37 properly bottomed, their ends 39 are peened over as if riveted.
  • the reason for not allowing rotation of the lugs 37 in the openings 38 is because the flange 49 on the free end of each of the lugs is eccentric of the lug so that the flange does not extend above the lug. but only below it. The reason for this is to prevent the flange 40 from being caught on the upper end of an opening 20 when the apparatus is being disassembled.
  • each is positioned with another immediately adjacent to it laterally.
  • the enlarged circular portion 201! is of a diameter larger than the diameter of the flanges 4% of the lug 37 so that the lug 37 can freely fit through it.
  • the body portion 37:: of the lug is slightly smaller than the width of the elongated hole portion 2% so that the lug can be dropped down into the elongated portion 2012 after it has been passed through the circular til portion Zita.
  • each sliding bolt 41 is of L-shape having a handle length 42 connected at right angles to a body portion 43.
  • the body portion 43 is mounted through a circular opening 44 of slightly larger diameter than the circular shape of the bolt 41 so that the bolt is freely slidable therethrough.
  • the hole 44 is in an S- shaped support 45 which is welded to the wall 34 of the end flange 35.
  • the end flange 34 is also provided with a hole 46 of the same diameter as the hole 44 so that the bolt 41 is ordinarily suspended through these two holes 44 and 46.
  • the handle 42 of the bolt projects out of an L-shaped opening .7 in the side wall of the tube 31.
  • This L-shaped hole 47 has a horizontal length 47:: into which the bolt can be shifted in order to retract it to its inner position as indicated in bold outline in FIGS. 2 and 5 where its end 41:: is recessed completely within the beam.
  • the hole 47 is provided with a downwardly extending portion 47b into which the handle 42 can be moved or dropped by gravity in order to maintain the bolt 41 in its extended position as indicated in phantom lines in FIG. 2 and in bold outline at the left hand side of FIG. 3.
  • the subject matter specifically relating to the bolt support 45 and its relationship to the beams supporting it is not claimed in this application, but is contained in a subsequently filed application of George E. Rasmussen, Serial Number 50,617, filed August 19, I960.
  • the bolt 41 When the beam 6 is in position as shown in FIGS. 2 and 3, and the wall 34 of the end flange 35 is drawn up tightly against the wall 23 of the upright, the bolt 41 is extended so that its end 41a projects out through the hole 46 of the end flange 35. With the parts positioned as indicated, one of the second holes 22 is ali ned with the end 41a of the bolt 41. This positioning of the h les 22 is predetermined. With one of these holes 22 lined up with the end 41a of the bolt 41, extension of the bolt 41 through the hole 46 also extends it through the hole 22 in the upright.
  • the bolt 41 then acts as a bearing support in the plane of the wall 23 of the upright which wall 23 is at right angles to the front wall 21 Where the lugs 37 are positioned for bearing support.
  • this latch or bolt arrangement is that, in its extended position, the bolt 41 prevents disassembly of the beam 6 from the upright 23. This eliminates the possibility of accidental disassembly of a beam from an upright which mi ht otherwise occur as a worker manipulates his fork lift truck when arranging pallet loads on the pallet rack structure. It is conceivable that the operator can accidentally position the forks of the lift truck beneath one of the beams whereby sudden operation of the forks of the truck in an upward direction might easily disassemble a beam if not secured to the upright in the manner shown.
  • the bolt 41 is entirely contained within its beam in such a way that it cannot be separated from it. In this manner, there is no chance of losing it and it is always available when needed. On devices where there are separate connectors which are not integral with the beams or the uprights, there is always a chance of losing the connectors and, through inadvertency or laziness, leaving them off the connection so that an inferior connection results. In this device, the bolt 41 is always there and always positioned properly so that there is no doubt as to how to connect it and it always insures a well connected joint between the beam and its upright.
