Definitions

  • ABSTRACT An overhead track assembly forming an aerial runway (22] Filed:
  • I973 downwardly open channels constitute support rails F n 7100 54 which are hung on yokelike hanger brackets from an 2 I973 Fmne 7103315 overhead support. One leg of each rail is received in a groove in each bracket and a setscrew is tightened in Mar.
  • each rail defines with the facing rail a gap down through which extends the hanger arm of a trolley whose rollers each ride on one of the rails.
  • These other legs may be ehamfered so as to permit lateral displacement of the hanger arm and this hanger arm has at least one roller engageahlc with the other legs to insure ease of riding.
  • the rails are formed of a plurality of in-line rail sections whose ends are secured together by connecting pieces between the legs.
  • PATENTS of the legs is formed with an inwardly directed ridge and the connecting piece is formed to snugly engage in the space between the two legs of the rail and he clamped in place with a setscrewl l ////i/l PATENTEDAPR 81975 SHZET 1 BF 2 PATENTEDAPR ems susnap z FiG.3
  • the present invention relates to an overhead track system. More particularly this invention concerns an overhead track and trolley suitable for the transport of goods. such as meat in packing houses.
  • the standard overhead track systems of the bar, Coburn. or double I-beam types have a generally horizontal track formed of a plurality of longitudinally joined rails which are supported at regular intervals with hangers secured overhead. Trolleys having wheels or rollers riding on support surfaces of the track serve to suspend loads which then can be pushed along the track. Such a system is practical in that it allows the transport of heavy and otherwise unwieldy objects readily, yet takes up no floor space.
  • the rail is bolted to hangers which lie along one side of the bar, permitting the trolley to pass along the other side.
  • the Coburn system has rolledsteel track forming a passage opening through a central slit in its bottom wall so that the rollers roll inside the rail while the load is carried on an arm projecting through the slit.
  • the double Lbeam system uses two I- beams to form the track. with the trolley riding between them.
  • hanger brackets must be affixed at predetermined intervals from each other where the rails are drilled to receive connecting bolts. or the rails must be redrilled to change the spacing. in practice it may be necessary to space the brackets apart by a distance smaller than the desired spacing or to position the brackets at unsuitable locations. This does not permit optimum spacing and positioning of the brackets.
  • Another object is the provision of such a system, especially suitable for the transport of foods, which is simple in design and easy to assemble.
  • a further object is to provide a system wherein the rail is protected against lateral deflection of the trolley.
  • the rail has an upper horizontal support surface for the trolley and is formed with a projecting flange which extends the full length of the rail.
  • the brackets are formed with recesses which receive the flange, and means is provided at each bracket to clamp the flange in the respective recess.
  • the rail is simply gripped by the brackets which therefore can be placed anywhere along its length.
  • the track is formed of parallel spaced rails or channels each formed as an inverted U with one leg constituting the clamping flange and another leg turned toward the other leg ofthe other rail.
  • the clamping means is a simple screw threaded in the bracket in a hole opening into a slot which constitutes the recess receiving the holding flange.
  • each rail serves as a lateral support for the trolley which is provided with a roller pivoted about an upright axis.
  • lateral deflection of the trolley causes one of its side rollers to engage the inside rail leg. allowing this trolley to roll along unimpeded.
  • the inner legs of the rails are formed at their lower edges with a bevel or chamfer giving the space between these rails a downwardly diverging cross sectional shape. These legs are thickened considerably at these bevels and rest with their inside faces against the bracket.
  • each rail is formed with a horizontal laterally-projecting flange which is adapted to engage in a similarly shaped slot of a connecting element adapted to fit snugly within the rail.
  • This element is fitted into the ends of two rails to be joined. and screws threaded in transverse holes in the element are tightened to exert force against the rails and prevent slippage of the rails relative to the element and. therefore. to each other. There are no exposed surfaces. except those ofthe rail itself on which dust or dirt can collect.
  • FIG. 1 is an end view of a rail according to the present invention
  • FIG. 2 is a vertical section through an assembly using the rail of FIG. 1;
  • FIG. 3 is a view similar to FIG. 2 showing another configuration according to this invention.
  • FIG. 4 is a cross section through a holding element or connecting piece usable with the rails of FIG. 3;
  • FIG. 5 is a cross section through the element of FIG. 4 mounted on one of the rails of FIG. 3;
  • FIG. 6 is a side view of an assembly as shown in FIG. 3.
  • FIGS. land 2 a pair of rails I having the general shape of a downwardly open channel having a pair of parallel legs 2 and 3, the former being shorter than the other and being formed on its outside face with a longitudinally extending groove 25 and the latter being longer and being formed on the lower end of its inner face with a longitudinally extending ledge 10.
  • a web 30 joins these legs 2 and 3.
  • the hanger 4 comprises a generally U-shaped steel yoke having transverse reinforcing flanges 6 and a mounting flange 5 adapted to be bolted to the ceiling shown at 26.
  • the hanger 4 is formed with a pair of inwardly directed support blocks 7 each formed with a respective longitudinally extending slot 8 and with adjacent its lower edge a ledge 27.
  • Each rail 1 is supported at each hanger 4 on one of its blocks 7 with the web 30 lying on the horizontal upper surface of this block 7, the lower edge of the leg 3 standing on the ledge 27, and the leg 2 received in the slot 8.
  • the hanger 4 is formed with a threaded hole 28 extending between its outside and the slot 8 so that an Allcn screw 9 can be screwed into this hole to bear on the leg 2 at the groove 25 and thereby tightly secure the rail 1 in place.
  • a trolley 29 has an upright support l5 from which a load L is hang and which carries at its upper end a transverse horizontal shaft 14 on which two rollers 12 are mounted via roller berings 13.
  • Each of the two rollers l2, only one of which is shown. rides on a respective rail 1 on the horizontal upper face of its bight or web 30.
  • the upright support arm 15 is provided on each side with a cylindrical roller 16 which rides against the leg 3 of the respective rail I.
  • the rails l are joined together longitudinally by means of short bars 11 of rectangular cross section which are welded to the insides of these bars between the ridges l0 and the web 30. having a thickness equal to the height of the ledge 10 so as to he receivable within the bracket 4 if it happens to fall at that location.
  • FIGS. 3-6 The arrangement of FIGS. 3-6 is similar to that of FIGS. 1 and 2 with like reference numerals being used for functionally similar structure.
  • each leg 3' is chamfered at 18 on its outer face on its lower edge and is correspondingly thickened at l) on its inner face.
  • the block 7 is formed with a flat face 31 having no ledge 27 and each leg 3 is formed on its in side face above the thickening I) with a horizontal in ⁇ vardly directed short flange 20.
  • These rails l are se cared to the holder 4 with screws 9 as in FIGS. 1 and 2.
  • the rails l are joined longitudinally by connecting pieces or bars 22 comprising short prefilcd steel bars formed with a cross-sectional shape conforming closely to the inside shape of the bars 1'. and having a groove 23 adapted to receive the flange 2".
  • Each element 22 is formed with two longitudinally spaced transverse threaded bores 230 each opening perpendicular to the surface 32 left exposed at one end and at the other end at the groove 23 and at the face 33 turned against the inside face of the leg 3' above the thickening l).
  • the face 33 is cylindrically curved or shaped as a plane warped around an upright axis. as is the side of the groove 8 opposite the screw 9 so that a slight misalignment of the hangar yoke and the rail is possible. as is use of a curved rail.
  • the trolley 29' is provided with a single barrel roller 16' which rides against the one or the other rail 1'.
  • FIG. 3 shows how when the trolley 29 is tipped radially this roller 16' remains in contact with one of the rails l and the stem 15 is allowed to deviate considerably from a vertical position by the chamfers 18.
  • An overhead track assembly comprising:
  • At least one elongated rail having an upper horizontal support surface and at least one projecting flange extending longitudinally the full length of said rail; at least one hanger having a recess receiving said flange, and
