Description
~06G,~D6~
Ths inventlon relates to systems adapted to anchor-a load on a flatbed, and more particularly, to load anchoring systems of the type adapted to anchor a container on a flatbed.
Chains are sometimes used tlD secure eontaiDers on flatbeds.
This is not considered practical and saltisfactory due to the time taken to manipulate the chains and to the encumbrance and welght of the chain5.
There has also been previously proposed a container coupling mechanism but the latter disadvantageously requires special ConStr~CtiOn of the containers to attach such coupling ~echanism thereto. ;-It is a general ob~ect of the present invention to provide a load or container anchoring system which substantially avoids the above ;~
mentioned disad~antages.
It is an object of the present invention ~o provide a load or container anchoring system which is adapted ~o be us~d with existing containers withou~ alteration thereof or modification thereto.
It is another ob~ect of the present invention to provide -~
a load or container ancho~ing system w~ich is simple and easy to operate and readily and safely anchors a container or load on a flatbed.
The above and other objects and advantages of the present in~ention will be better understood with reference to the following detailed description of preferred embodiments thereof which are illustrated9 by way of examples~ in the accompanying drawings~ in which:

On each end of the trans~erse beams S there is secured a guide plate 9 which is inclined downwardly inward to properly position the container transversely relative to ehe flatbed. Thus, the apert~res 7 are positioned in predetermined posit~Lon t~ansversely oE the flaebed.
A baseplate 10 is rigidly secured at eah end of the transverse beams 5 and to the latter. An aperture extends thr~ugh each end of the beams 5 and a plate 11 is fixsd edgewise upright inside and in alignment with each aperture to cooperatively form a slideway in the correspondiog apertureA Such slideway is substantially parallel to the flatbed 2 and transversely extPnds through the outer end of corresponding transverse beam 5~ Thus~ each s~ch slideway extends longitudinally of the flatbed. Right above each slideway there is provided a boss 12 which is adapted and arranged to fit in the bottom of a corner post 8 and to thus positively locate the corner of the container in vertical register with the outer end of the beam 5.
For each co~ner post 8 or end of the beam 5 the anchoring system of Figures 1 to 4 inclusive inoludes an anchorin~ member 13 and a corresponding lever 14. me anchoring member 13 has a lo~er `
portion forming a slide slidablg engaged in the sl$deway of the corresponding end of a beam 5. mis slide is formed by a pair of parallel bars 15 engaged on opposite sides respectively of the corresponding plate 11 and so retained by a block lS welded between the frse ends of the bars, The ~atters are of sufficient length to allow sliding of the anchoring member 13 transversely of the beam 5 and to and ~ro relative to the corresponding container and in a plane substantially parallel to flatbed 2. The anchoring member~
13 includes a prorg 17 which pro~ects endwise toward the corresponding corner post 8 to engage ~n the aperture 7 thereof and thus anchor `~
the container on the flatbed. The lever 14 is reely pivoted at one end on a pin 18 fixedly secured to the corresponding beam 5. The lever 14 thus freely piv~ts transversely relative to the path of displacement to intercept the anchoring member 13 and ou~ardly - 4 ~
665~3l register the~ewith, shown in Figures 1, 3 and 4, to block the anchoring ember 13 ag~inst outward reeraction of the prong 17 from the corresponding aperture 7. The ~eight of the lever 14 simply holds :~
the latter against accidental release of the anchoring member 13.
As may be seen from Figure 1~ the anchoring system in this embodiment includes an anchoring member 13 and a le~er 14 at each of the four ends defined by the two transverse beams 5 to anchor the container at each corner post thereof.
The container or load anchoring system of Figures 5, 6, and 7 -includes a beam assembly 19 oonsisting of a pair of spaced eransverse beams 21 united together near each of their two ends by a longitudinal link 20. Apertures are provided through the ends of the transverse beams 21. A rod 22 extends into the apertures through one end of the beams 21 along ~ach side of the flatbed and is retained by cotter pins 22'. The rod 22 forms a slideway extending between a pair of ad~acent containers 6' and eDdwise relative to the latter. The containers 61 .
have half the length of containers 6.
A pair of anchoring members 23 are slidsbly mounted on the rod 22 and include each a slee~e portion 24 and a prong 25 projecting on the same side toward the corresponding container 6~. The sleeve portion 24 is adapted to engage in the annular space 26 deflned ~
around the rod 22 in the corresponding end of the beam 21. The prong ~ .
25 engages end~ise in the aperture 7 until abutment of the anchoring me~ber 23 against the corresponding beam 21.
A leYer 27 is pivoted on the prong 25 of each anchoring :
member 23 and arranged to engage in ~he aperture 7 and be pivoted in the latter transversely of the prong. This is sho~n by the arrow 28 and the dotted line position of this lever 27 is Figure 7. This -lever 27 thus blocks the anchoring member 23 in anchoring position against retraction from the corresponding corner post 8. A lug 29 is fixed to each lever 27 and outwardly pro~ect to limit the pivoting of the latter ~nd to prvvide a grip to pivot the leYer for withdrawal thereof from the aperture 7.
me anchoring system illustrated in Figures 8 and 9 like the system of Figures 5~ 6 and 7 includes the beam assembly 19, the link 20, -f ~
' ~0665~
the transverse bea~ 21, the ~od 22, the pa:lr of anchorlng members 23 on each rod 22, a sleeve portion 24 and a prong 25 on each anchorin& member 23, and an annular space 26 in each end of the beam 21 around the rod 22.
In this embodiment of Figurles ô and 9, the pronge 25 are distinctively blocked in anchoring position by a plate 30 pivoted on a pin 31 extending parallel to the rod 22 and secured at its opposite ends in the beams 21 respectively. A pair of springs 32 are engaged `-around the pin 31 on the opposite sides of the plate 30 to axially center the latter relative to the beams 21 and thus to the two adjacent container. The pronge 25 in this case are blocked in anchoring position by engagement of the pi~oted plate 30 between the corresponding anchoring members 23.
It must be noted tha~ many changes in the details of construction are possible and fall within the spirit and principle of the ~.
