Definitions

  • This invention relates to a cargo restraining device and in particular to a device having a platform for receiving a pallet loaded with cargo and restraining the pallet against movement when placed in a carrier.
  • Patent No. 4,147,112 issued to Greene et al, relates to a cargo support or retainer which endeavors to avoid banding, blocking, or bracing of palletized cargo loads, by providing a substantially L-shaped frame, wherein the lower horizontal member which con ⁇ tacts the floor is provided with a plurality of "anti ⁇ skid" spikes.
  • This device while reasonably effective, has yet been found less than ideal for maintaining load integrity under a number of conditions, including when used in truck trailers mounted for piggy-back service on railroad cars.
  • the spikes cannot be used on the metal floors which are found e.g. in refrigerat ⁇ ed trucks and railroad cars; and further, it is found that the mere substitution of rubber pads for the spikes does not solve this problem.
  • a further cargo restraining device is disclosed in U.S. Patent No. 4,317,645 issued to the co-inventor herein, James Van Gompel.
  • an elongated floor contacting member is provided with an upwardly facing load-bearing surface, the member being adapted to project forwardly beneath a portion of the cargo load.
  • a generally upright member is secured to the floor contacting member in spaced relation from the forward end of the floor contacting member for engaging with the cargo load, and a floor piercing element is movably mounted on the floor contacting member adjacent to the rearward end thereof.
  • the floor piercing element is normally disposed to pierce the floor when the floor contacting member of the restraining device is under load in service, and is movable to a position incapable of piercing the floor when the restraining device is out of service.
  • This device is generally not of value with the aforementioned metal floored cars and truck vehicles, as the floor piercing elements either cannot engage the metal surfaces or simply damage same.
  • patent No. 1,559,827 issued to Wittman relates to a freight anti-creeping device including a platform hav ⁇ ing spikes in its underside for gripping the floor, and a projecting lug on its upper face to which the cargo is wired. This projecting lug requires an opening in the cargo, or else the cargo must be mounted around the lug.
  • Patent No. 1,638,612 to Baus relates to a device for shipping boxes, which includes anti-skid plates between the boxes and the floor and clamp bars over the boxes, which are drawn to the floor by rods anchored adjacent the floor, blocks being secured to the boxes for preventing movement between the clamp bars and the bo es .
  • Patent No. 2,420,640 to Acteson relates to a demountable pallet crib having frame members which en ⁇ close the perimeter of the pallet and form an open-work frame to enclose the cargo.
  • Still another object of the invention is to pro ⁇ vide a device for securing and releasing a palletized load in a carrier, which is simple to construct and easy to operate.
  • a yet further object of the invention is to provide a device for securing and releasing a palletized load in a carrier of the type intended to refrigerate a load, which carrier is provided with a metal floor with ribs or spaced longitudinally-extending channels which allow cold air to circulate around the cargo.
  • a cargo restraining device for a palletized cargo load which includes a horizontal platform for receiving the pallet with the cargo load thereon, and a vertical frame at one end of the platform, against which the cargo can abut.
  • a handle is pivotally secured by a double pivot to the frame and to a vertically-extending assembly, the lower end of which is adapted to friction- ally engage the floor of the carrier. Displacement of the handle means by an operator functions to move the said lower end of the vertically-extending assembly into contact with the floor, while at the same time exerting an upward jacking force on the adjacent end of the cargo supporting platform.
  • the handle is pushed downwardly, which pushes the vertically-e tending assembly away from the vertical frame and horizontal platform, and toward the floor — i.e. the lower end of the assembly moves below the plane of the pallet. This in turn tends to lift one edge of the pallet in jack-like fashion, adding the weight of the cargo to the downward force on the ver ⁇ tically-extending assembly.
  • Continued movement of the handle locks the vertically-extending member in its ex ⁇ tended position restraining the pallet against movement. Since the pallet is also frictionally secured to the platform by its own weight, the cargo is securely held in place.
  • FIGURE 1 is a perspective view showing a palletized cargo load supported by a cargo restraining device ac- cording to the invention
  • FIGURE 2 is a partial perspective view of the cargo restraining device released from the floor of a carrier. ⁇ -
  • FIGURE 3 is a partial perspective view of the cargo restraining device secured to the floor of the carrier;
  • FIGURE 4 is an end elevational view from the verti ⁇ cal frame end of the cargo restraining device in a mode where it is clamped on the floor of the carrier;
  • FIGURE 5 is a side elevation view of the cargo restraining device in the mode where it is secured to the floor of the carrier.
  • FIGURE 6 is a partial plan view of the platform portion of the cargo restraining device according to the invention.
  • a palletized load 10 is shown, supported on a conventional pallet 12, the load and pallet being associated with a cargo-restraining device 5 in accordance with the present invention.
  • load 10 can be illustratively regarded as being of a type requiring ref igeration in shipment. Usually, therefore, such loads are shipped in refrigerator truck bodies or re- frigerated railway cars.
  • the floors of these carriers commonly comprise steel or the like, and channels or troughs often extend lengthwise in the carrier floors enable refrigerated air to be circulated for load cooling.
  • Pallet 12 generally comprises an upper supporting surface 14 comprising a plurality of wooden planks, and a lower surface 16 comprised of similar planks, with the upper and lower surfaces being separated by cross- ties 15, one of which 15a ( Figures 2 and 3) , is at approximately the center of the pallet.
  • cross-tie 15a slides or is received into into a slot 17 between two generally triangular-shaped plates 18, 19, (FIGURES 2, 3 and 6) , which comprise the horizontal portion of the generally L-shaped device 5 (FIGURE 5) , and which thus form a platform 20 for the loaded pallet.
  • This insertion of the platform into the space between surfaces 14 and 16 of the pallet 12 is facilitated by the narrowing of the distal end of platform 20 achieved by convergence of the hypotenuses of the triangular plates 18 and 19.
  • each triang ⁇ ular-shaped plate 18 and 19 are secured to a lower horiz ⁇ ontal beam 26 of a generally rectangular vertical frame 28 ( Figures 1 and 4) , having upright legs 28a and 28b, and an upper cross-beam 30.
  • the upper 30 and lower 26 cross-beams and upright legs 28a and 28b of the vertical frame 28 are braced by diagonally extending members 32.
  • a handle 34 is secured at each end to a hinge 46 by a pin 38 which is pivotally secured to a plate 40 connected to the vertical legs 28a and 28b of the frame , by a pin 42. Hinge 46 is also connected to mem ⁇ bers 44 by pins 38.
  • Handle 34 is thus connected at each end, through hinge 46 and pins 38 and 42 to a gen ⁇ erally vertically-extending assembly which includes members 44.
  • the lower ends of members 44 are surrounded by bumper guards 47a and 47b, and are connected to a cross-bar 48 carrying on its underside a horizontally extending member 50 secured to the cross-bar by a bolt
  • cross-bar 48 With the handle 34 in the upper position ( Figure 2) , cross-bar 48, and in particular member 50, is above the plane of the bottom of the pallet, and is thus above the floor of a carrier or supporting surface.
  • member 50 Upon handle 34 being moved to the lowered position ( Figures 1 and 3) however, member 50 first contacts the underlying carrier floor 101 or other supporting surface and thus is extended below the pallet and to a position laterally displaced to one side of the frame 28, to prevent move ⁇ ment of the device 5 with the load thereon.
  • horizontally extending member 50 comprises, or is covered with a highly frictional material such as rubber, in order to obtain a greater frictional force from its contact with the floor.
  • handle 34 is grasped and displaced downwardly while pushing against frame 28, which will result in horizontal member 50 contacting the vehicular carrier floor 101 and then slightly tilting the load as previously discussed, to restrain movement of the device 5. Frictional contact of the horizontal member 50 with the vehicle carrier floor is increased by the weight of the load on the pallet which has tilted rearwardly, placing further force on the horizontal member 50. The weight of the cargo load on the upper supporting surface 14 will firmly hold the pallet in place on the restraining device 5.
  • the palletized cargo is firmly secured and prevented from moving while it is being transported.
  • the handle 34 Upon reaching its destination, to release the pallet with its cargo load, the handle 34 is returned to its upper position which lifts the horizontal member 50 off the carrier floor. The pallet can now be removed from the restraining device.

Abstract

Un dispostif de retenue des cargaisons, pour chargements sur palettes, comportant une plateforme (16) pour recevoir une palette chargée (10) et un cadre vertical (28) situé à une extrémité de la plateforme. Une poignée (34) est fixée, de manière pivotante, au cadre (28) et est reliée à un élément à mouvement horizontal (50) pouvant être déplacé pour entrer en contact de frottement avec un plancher ou une surface d'appui. Pour verrouiller la palette et la plateforme au plancher (101) on pousse la poignée vers le bas tout en poussant le cadre vertical (28) vers la charge. Le mouvement de la poignée, qui tourne autour d'une charnière (42) liée par pivotement au cadre, déplace l'élément à mouvement horizontal (50) pour le mettre en contact avec la surface d'appui (101) et en même temps soulève et fait basculer la plateforme (16), ce qui applique à l'élément à mouvement horizontal (150) en contact avec la surface d'appui une force plus grande vers le bas.
