Container-securing device
A container-securing device is provided. A main body of the container-securing device is detachably/attachably supported on a cargo bed yet movement of the main body is restricted in any direction within the horizontal plane. The container-securing device 1 includes a socket 3 which is fixed onto the cargo bed; and a main body 2 which is fixed into the socket 3 to fix a container: The main body 2 has its lower region formed with projections 22 b extending horizontally; and the socket 3 has a storage space 31 to store the projections 22 b , a first restrictor 32 around the storage space 31 which allows rotation of the projections 22 b within a horizontal plane but restricts other movement thereof in any direction within the horizontal plane, an opening 33 which communicates with the storage space 31 and allows the projections 22 b to be inserted through, and a second restrictor 34 around the opening 33 which restricts movement of the projections 22 b in the vertical direction.
1. A container-securing device comprising: a socket to be fixed to a cargo bed; and a main body to be attached to the socket for fixing a container; wherein the main body has a lower region formed with a horizontally projected projection, the socket is provided with: a storage space for storing the projection; a first restrictor around the storage space which allows rotation of the projection within a horizontal plane but restricts other movement of the projection in any direction within the horizontal plane; an opening which communicates with the storage space for insertion of the projection; and a second restrictor around the opening which restricts movement of the projection in a vertical direction,
the main body is provided with a pin which is protruded by an elastic force from an elastic member and is retractable against the elastic force from the elastic member, and the socket is provided with a guide which gradually retracts the pin as the main body rotates to move the pin along an arc, and a stopper which makes engagement with the pin as the pin passes the guide and protrudes, for stopping rotation of the main body.
2. The container-securing device according to claim 1 , wherein the socket is formed with a contact portion which makes contact with the pin in a protruding state if there is an attempt to insert the projection into the opening in an incorrect orientation.
3. The container-securing device according to claim 1 , wherein the socket is provided with an over-turn preventer which restricts the projection from rotating beyond a predetermined range in the storage space.
4. The container-securing device according to claim 1 , wherein the main body has a fitting portion for fitting into a groove hole of a corner casting of the container; a movable protrusion provided in the fitting portion for pivoting on a horizontal shaft to protrude in a lateral direction; and a stopper which restricts the pivotal movement of the movable protrusion.
5. The container-securing device according to claim 2 , wherein the socket is provided with an over-turn preventer which restricts the projection from rotating beyond a predetermined range in the storage space.
6. The container-securing device according to claim 2 , wherein the main body has a fitting portion for fitting into a groove hole of a corner casting of the container; a movable protrusion provided in the fitting portion for pivoting on a horizontal shaft to protrude in a lateral direction; and a stopper which restricts the pivotal movement of the movable protrusion.
7. The container-securing device according to claim 3 , wherein the main body has a fitting portion for fitting into a groove hole of a corner casting of the container; a movable protrusion provided in the fitting portion for pivoting on a horizontal shaft to protrude in a lateral direction; and a stopper which restricts the pivotal movement of the movable protrusion.
