Definitions

  • ABSTRACT A pivot bolt arrangement for securing a container having socket-type openings to a housing mounted on a chassis frame support is arranged to be retracted into the housing when not in use.
  • the housing fonns a hollow or open space into which the bolt is retracted.
  • the bolt extends upwardly through an opening in the top of the housing with its head resting on a collar.
  • the bolt can be pivoted relative to the collar for securing the container to the housing.
  • a pivot handle is attached to the bolt for rotating it and for retracting it into the housing 5 Claims, 8 Drawing Figures PAIENTEBFEB22 I972 SHEET 1 [IF 5 INVENTOR5 HANS WERNER BALDUR Koschlmmr AND 0110 voRMsAuM B $56M Im Aflumeys PATENTEOFEB22 I972 3.643 .906
  • the invention is directed to a turning or pivot bolt arrangement positionable within socket-type openings in a container for securing the container on a chassis frame support, and, more particularly, it is directed to the arrangement of the bolt which can be adjusted for securing different thicknesses of the container plate to the support and also for retracting the bolt into a housing when it is not in use.
  • the same frame support should be usable for attaching a normal superstructure to the truck or for securing one or several containers in place.
  • pivot or turning bolts When pivot or turning bolts are used, for securing the containers in position, they project upwardly from their guide collars through the frame support and are in the way when not in use.
  • pivot bolts which can be detached from the chassis frame. In such a case, the bolts are carried loosely in the truck as long as it supports a conventional superstructure.
  • the changeover operation is time-consuming and, in addition, there is the risk that one or a number of the bolts not secured in position will become lost.
  • the operator of the truck attempts to secure the container with the remaining bolts and, as a result, the bolts become overstressed and tend to break so that the container is not adequately secured and may fall off the truck.
  • the primary object of the present invention is to provide a pivot bolt arrangement which is secured to the chassis frame support of the truck at all times and which can be retracted into a housing or similar structure so that it does not cause any interference when it is not in use.
  • a connecting element composed of a housing is attached to the truck frame support and is arranged to receive the pivot bolt.
  • the housing is formed of a top wall and sidewalls which combine to provide an open or hollow space below the top wall into which the bolt can be retracted.
  • the housing is secured to the frame support along one of its sidewalls which has a height somewhat less than the height of the web of the frame support so that a fillet weld can be formed along the top of the sidewall for securing it to the frame support at a position below the top surface of the frame support.
  • a noncircular opening is provided within which the guide collar for the pivot bolt is positioned and a certain amount of play is provided so that the collar can be retracted into the housing by means ofa pivot lever.
  • the sidewalls of the housing provide a cylindrically shaped housing section in which an L-shaped slot is provided for guiding the pivot lever as it positions the bolt.
  • One portion of the L-shaped slot extends horizontally and a second portion extends vertically downwardly from the horizontal section.
  • Stop members are secured to the exterior of the housing adjacent the slot for securing the pivot lever in position.
  • the pivot lever is formed of a hinged construction composed of a first part disposed in the horizontal position and a second part hinged to the first part for movement between a horizontal position and a vertical position. In the horizontal position, the second part extends axially from the first part so that the pivot lever can be positioned through the slot and when the second part is moved into the vertical position the pivot lever is secured in place.
  • Another feature of the invention is the construction of the pivot bolt arrangement so that it can be employed for securely attaching two different standardized plate thicknesses of container plate to the truck frame support.
  • the adjustment to different thicknesses of the container plate can be made by positioning the pivot lever in selected locations within the horizontal part of the L-shaped slot in the housing. At the end of the slot remote from the vertical section, a downwardly inclined end part can be provided to receive the pivot bolt as it is turned transversely to its guide collar and lowered relative to the remaining part of the horizontal section for adjusting to the thickness of the con tainer plate.
  • the bolt head locks the container to the housing and, in turn, to the frame support when the container plate containing the socket openings to which the bolts extend have a thinner standardized thickness.
  • the bolt is rotated by means of the pivot lever through the horizontal leg to its opposite end at the upper end of the vertical section of the slot. Since the container plate is positioned about the guide collar of the bolt, the bolt arrangement will not move downwardly through the vertical leg but will secure the container to the frame support.
  • a stop member is secured to the outer surface of the sidewalls of the housing to hold the pivot lever in position after its second part is moved from the horizontal to the vertical position. In this location, the bolt head is positioned in a relatively higher plane than when the pivot lever is positioned at the opposite end of the slot and, accordingly, it is capable of firmly securing a thicker container plate to the support.
  • the second section of the pivot lever can be hinged into its vertical position and folded against the outer surface of the housing.
  • the stops on the outer surface of the housing prevent the bolt from being displaced by vibrations generated as the truck is driven and, moreover, by folding the pivot lever downwardly the width of the vehicle is reduced.
  • a center position can be located in the horizontal leg of the L- shaped slot by means of a depression located between the stops which identify the end positions of the pivot lever.
  • another slot having a width through which the pivot lever can pass is disposed upwardly from the horizontal leg of the L-shaped slot through the sidewalls of the housing and extending to the top of the housing.
  • the bolt arrangement which is adjustable for two different standardized plate thicknesses and in which a hinged support of the bolt arrangement is provided for displacing the bolt into the housing so that it does not provide any interference above the surface of the frame support of the truck.
  • at least one supporting lever secures the bolt arrangement in its locking position by means of a spring-loaded construction. When the lever is displaced from its supporting position, the bolt arrangement can be rotated about a pivot support into a retracted position within the housing.
  • the pivot bolt When the pivot bolt is rotated into its retracted position along with the guide collar, it does not project either upwardly or downwardly relative to the chassis frame support and, as a result, can be integrally attached to the frame support without affecting the clearance between the frame support and the ground.
  • the pivot bolt can be adapted to secure different thicknesses of container plate to the frame support.
  • FIG. 1 is a front perspective view of one embodiment of the present invention for securing a container to a frame support by means of a pivot bolt arrangement;
  • F IG. 2 is a perspective side view of the arrangement shown in FIG. 1 with a handle illustrated in the folded down position as compared to the horizontal position in FIG. 1;

  • FIG. 8 is a side view, partly in section, of the embodiment illustrated in FIG. 7 in a position similar to that illustrated in FIG. 4.
  • a bracket-type housing 2 is welded along one of its upper edges to a section 1 ofa chassis frame support, not otherwise illustrated.
  • the housing is constructed of a top wall 7, having a rectangular shape, and sidewalls which are disposed along three sides of the housing with one sidewall abutting the frame section 1 of the chassis frame support.
  • an open space is provided below the top wall 7 in which an inner cylindrically shaped housing wall section 3 is positioned.
  • An opening 6 of irregular or noncircular shape extends through the top wall 7 in alignment with the cylindrically shaped housing section 3.
  • a hammer headshaped bolt 4 is shown in the unlocked position of the bolt arrangement extending upwardly from the top wall 7 of the housing 2 and rests on a similarly hammerhead-shaped guide collar 5 which also extends upwardly above the top wall of the housing.
  • a pivot pin or journal extends downwardly from the bolt 4 through the collar 5 into the housing section 3.
  • a pivot lever 8 Secured to and extending radially from the pivot pin below the top wall 7 of the housing is a pivot lever 8 which extends through an L-shaped slot 10 in the wall of the housing section 3.
  • the L-shaped slot 10 is formed ofa vertical leg 9 which extends downwardly from one end, the left end as viewed in FIG. 1, of a horizontal leg 12 of the slot.
  • the pivot lever 8 is shown at an intermediate position in the horizontal leg I2 of the slot 10.
  • the pivot lever 8 has a handle hinged to its radially outer end and the handle is movable between a horizontal position, see FIG. 1, and a vertical position, see FIG. 2.
  • stop members 13 and 14 are positioned below the horizontal leg 12 of the slot 10 which cooperate with the handle 15 ofthe pivot lever 8 when it is in the vertical position to prevent displacement of the pivot lever and, in turn, ofthe bolt.
  • the bolt By moving the pivot lever through the horizontal and vertical legs 12, 9 of the slot 10 the bolt can be rotatably displaced for securing a container in place on the frame support 4.
  • the bolt arrangement By aligning the pivot lever with the vertical leg 9 and moving it downwardly therethrough, the bolt arrangement can be retracted into the housing so that it does not obstruct or project above the housing and interfere with the use or operation of the truck.
  • the socket-type opening of a container plate construction which fits over the bolt and around the guide collar does not form a part of the invention, and since it is well known, is not illustrated in the drawing.
  • the end I l of the horizontal leg 12 of the slot is enlarged in the downward direction so that the lower edge surface of the slot extends downwardly from the normal plane of the edge surface for the remainder of the slot.
  • the stop member 14 is positioned adjacent the end I l of the slot.
  • the handle 15 of the pivot lever can be locked in its vertical and horizontal position by means of a cup spring, not shown, located in the inner end face of the handle.
  • a center position of the bolt 4, as represented in FIGS. 1 and 2 is provided by a depression 16.
  • This depression 16 makes it possible to locate the turning bolt easily in its center position and, if necessary, stop members may also be located adjacent the center position for locking the pivot lever handle in position.
  • the bolt can be rotated by means of the pivot lever 8 and its handle 11 into either of the locked positions at the opposite ends of the horizontal leg 12.
  • the pivot lever selectively at one or the other ends of the horizontal leg of the slot. If the container has a thicker plate section, the pivot lever and its handle are turned to the left-hand end, as viewed in FIG. 1, of the horizontal leg 12 of the slot 10 so that the head rotates relative to the guide collar and holds the container plate section in position.
  • the handle is turned to the lefthand end, it is prevented from passing downwardly through the vertical leg 9 and by folding or turning the lever handle I5 downwardly it is locked in place against displacement by means of the stop member 13 projecting outwardly from the surface of the housing section 3.
  • the pivot lever is turned from its center position at depression 16 to the right-hand end of the horizontal leg 12 and into the downwardly extending end 11.
  • the collar guide 5 and the bolt 4 recede toward the top wall 7 of the housing 2 and the bolt contacts the thinner wall section of the container and secures it in place.
  • the handle 15 is folded downwardly into the vertical position and is secured against displacement by means of the outwardly projecting stop member 14 on the outer surface of the housing section 3.
  • an assembly slot 17 extends through the housing from the horizontal leg 12 of the slot 10 through the top wall 7.
  • a hammerhead-shaped pivot bolt 18 is provided with a square key 18a on its lower face and is secured to a pivot pin 19 which extends through the guide collar 20.
  • the bolt 18 is supported within a housing 32 having an opening in its upper surface and being open at its base to provide a hollow or open space into which the bolt can be retracted.
  • a pivot lever 21 is located at the lower end of the bolt arrangement and a U-shaped handle 22 is secured to the pivot pin 19 by means of a spindle nut 23 for rotating the bolt between its locked and unlocked positions.
