Abstract of the Disclosure A cargo container hold down device that includes a shear block defining a base and housing therefore that is shaped so that the base forms a planar surfacing thereabout on which the cargo container corner fitting rests in the applied relation of the container relative to the supporting platform involved; the shear block housing pivotally mounts a latch device comprising a latch member that includes a nose portion having an upper cam surfacing for engagement by a correspondingly located container mounted corner fitting, and an under cam surfacing disposed for engagement by such correspondingly located container mounted corner fitting on removal of such container therefrom, said latch member being biased outwardly of the shear block housing to dispose the nose thereof over the container corner fitting supporting surface of said shear block housing, and including means for withdrawing such latch member within said shear block housing about one pivot axis when the container is applied to the device, and means for withdrawing such latch member within the shear block housing about a separate axis that is spaced from and parallels the first indicated pivot axis when the container is removed from such device, so as to achieve a smooth and easier loading of the container, and provide for increased force for cam positioning of the device latch member for container removal purposes.

La présente invention a pour objet un dispositif de retenue pour conteneurs de marchandises; le dispositif en question comporte un bloc de cisaillement définissant une base et un boîtier formé de sorte que la base forme une surface plane sur laquelle les ferrures de coin du conteneur de marchandises viennent prendre appui; le boîtier du bloc de cisaillement loge un organe de verrouillage pivotant sur un axe et comportant un bec dont la partie supérieure présente un profil de came venant en prise avec les ferrures de coin des conteneurs de marchandises, ainsi qu'un profil de came inférieure correspondant à la configuration de la ferrure de coin des conteneurs de marchandises et facilitant leur dégagement; le dispositif de verrouillage en question est maintenu à l'extérieur du bloc de cisaillement par l'action d'un ressort afin d'exposer le bec de l'organe de verrouillage aux fins d'engagement avec les ferrures de coin des conteneurs de marchandises; un dispositif permet de désengager ledit organe de verrouillage des ferrures de coin des conteneurs par pivotement sur un axe de pivotement; l'organe de verrouillage peut aussi être désengagé du bloc de cisaillement par pivotement sur un différent axe de pivotement espacé et parallèle au premier axe de pivotement lorsque le conteneur est désengagé du bloc de retenue, de manière à faciliter le chargement et le déchargement des conteneurs de marchandises.
