Abstract

A system for securing a vehicle of the type having a plurality of wheels from rolling or sliding along the floor of a refrigerated-type cargo container, employs lashing point anchors which couple to the floor of the cargo container without damaging same. Generally, the floors of refrigerated-type cargo containers are delicate, as they are formed of a plurality of elongated floor sections formed of extruded aluminum. The floor sections are arranged parallel to, and at a predetermined inter-sectional distance from, one another, each elongated floor section having a horizontal top portion and a vertical portion arranged orthogonal to one another to form a T-shaped cross-sectional configuration. A plurality of lashing straps, each having first and second ends, are coupled between the vehicle and respective ones of the lashing point anchors. Each lashing strap has an associated length adjustment arrangement. The lashing point anchors are in the form of assemblies that are removably coupled with the floor of the refrigerated-type cargo container and have first and second lashing point assembly portions whereby when the lashing point assembly is coupled to the floor of the refrigerated-type cargo container, at least a portion of the horizontal top portion of the one of the elongated floor sections is interposed between the first and second lashing point assembly portions.

Dependent claims

An arrangement for securing an article to a floor of a refrigerated-type cargo container, the floor being of the type formed of a plurality of elongated floor sections arranged parallel to, and at a predetermined inter-sectional distance from, one another, each elongated floor section having a horizontal top portion and a vertical portion arranged orthogonal to one another to form a T-shaped cross-sectional configuration, the vertical portion having a predetermined height dimension, the arrangement comprising:

elongated bar means having a width dimension which is less than the inter-sectional distance between the top portions of adjacent ones of the elongated floor sections and a depth dimension which is less than the predetermined height dimension of the vertical portion, whereby said elongated bar means can be accommodated between an adjacent pair of the elongated floor sections beneath their respective top portions, said elongated bar means being provided with angled end portions for increasing the length of the communication between said elongated bar means and the underside of the horizontal top portion of the elongated floor section;
coupling means fixedly engaged with said elongated bar means, said coupling means extending upward above the top portions of the adjacent pair of the floor sections when said elongated bar means is disposed therebetween for engaging with the article;
tightening means for urging forcefully said elongated bar means toward the article to be secured to the floor, whereby portions of the horizontal top portions of adjacent ones of the elongated floor sections maybe interposed between said elongated bar means and the article to be secured to the floor, and
friction means coupled to said tightening means for preventing loosening of said tightening means in response to vibration and rotatively urging said angled end portions into communication with the vertical portions of respective ones of the elongated floor sections as said tightening means is tightened.

A lashing point assembly for forming a cargo lashing point on the floor of a refrigerated-type cargo container, the floor being of the type formed of a plurality of elongated floor sections arranged parallel to, and at a predetermined inter-sectional distance from, one another, each elongated floor section having a horizontal top portion and a vertical portion arranged orthogonal to one another to form a T-shaped cross-sectional configuration, the vertical portion having a predetermined height dimension, the lashing point assembly comprising:

a lashing point anchor having a base portion for communicating with the floor of the refrigerated-type cargo container, and a coupling portion formed integrally with said base portion for facilitating coupling of a lashing strap thereto;
elongated bar means having a width dimension that is less than the inter-sectional distance between the top portions of adjacent ones of the elongated floor sections and a depth dimension which is less than the predetermined height dimension of the vertical portion, whereby said elongated bar means can be accommodated between an adjacent pair of the elongated floor sections beneath their respective top portions, said elongated bar means being provided with angled end portions for increasing the length of the communication between said elongated bar means and the underside of the horizontal top portion of the elongated floor section;
coupling means engaged with said elongated bar means, said coupling means extending upward above the top portions of the adjacent pair of the floor sections when said elongated bar means is disposed therebetween for engaging with the base portion of said lashing point anchor, said coupling means being fixed onto said elongated bar means, whereby rotation of said coupling means rotates said elongated bar means;
and
tightening means for urging forcefully said elongated bar means toward said base portion of said lashing point anchor, whereby portions of the horizontal top portions of adjacent ones of the elongated floor sections maybe interposed between said elongated bar means and said base portion of said lashing point anchor, said tightening means being further provided with friction means for preventing loosening of said tightening means in response to vibration and for rotatively urging the angled end portions of said elongated bar means into communication with the vertical portions of respective ones of the elongated floor sections as said tightening means is tightened.
