Abstract

A locking device prevents a rod for closing a door of a container or truck from being rotated in an unlocking direction so as to keep the container doors locked, even if a control handle of the rod should be cut. The rod has is provided near the surface of the door so as to be rotatable about its axis into and out of engagement with door closing members fixed on the container body. The locking device has a first locking member mounted on the control handle at a base portion thereof, a second locking member mounted at a position opposite to the first locking member across the control handle, and a fixing member for inseparably fixing the second locking member to the first locking member. The second locking member prevents the rotation of the rod in the unlocking direction by abutting the surface of the door when the second locking member and the first locking member are inseparably coupled together around the control handle.

Claims16

Dependent claims

A door assembly and a locking device for said door assembly, said door assembly including a door having a pivotal door closing rod extending along a surface of said door and a control handle fixed to said door closing rod for pivoting said rod, said control handle having a base portion connected to said rod, said locking device comprising:

a first locking member comprising a first front wall confronting and contacting said base portion of said control handle, a pair of first horizontal walls extending substantially perpendicularly from said first front wall and receiving and contacting said rod, and a substantially flat coupling wall extending from said first front wall substantially parallel to said first front wall;
a second locking member engaged with said first locking member and positioned opposite to said first locking member with respect to said rod, said second locking member being a separate member from said first locking member and comprising a substantially flat second front wall, a rear wall extending substantially parallel to said second front wall and having a rigid substantially flat contact surface, and a pair of second horizontal walls connected to and extending substantially perpendicular to said second front wall and said rear wall;
said coupling wall being received in said second locking member parallel to said second front wall, with said rod held by said first and second horizontal walls, said control handle being held by said first front wall, and said rigid flat contact surface being juxtaposed with said door for contact therewith;
and
a fixing member inseparably fixing said coupling wall with said second front wall together with said coupling wall juxtaposed with said second front wall.

A locking device for a door assembly including a door having a pivotal door closing rod extending along a surface of the door and a control handle fixed to the door closing rod for pivoting the rod, the control handle having a base portion connected to the rod, said locking device comprising:

a first locking member comprising a first front wall adapted to confront and contact the base portion of the control handle, a pair of first horizontal walls extending substantially perpendicularly from said first front wall and adapted to receive and contact the rod, and a substantially flat coupling wall extending from said first front wall substantially parallel to said first front wall;
a second locking member adapted to be engaged with said first locking member and positioned opposite to said first locking member with respect to said rod, said second locking member being a separate member from said first locking member and comprising a substantially flat second front wall, a rear wall extending substantially parallel to said second front wall and having a rigid substantially flat contact surface, and a pair of second horizontal walls connected to and extending substantially perpendicular to said second front wall and said rear wall;
said coupling wall being configured to be received in said second locking member parallel to said second front wall so that the rod can be held by said first and second horizontal walls, the control handle can be held by said first front wall, and said rigid flat contact surface can be juxtaposed with the door for contact therewith;
and
a fixing member adapted to fix said coupling wall with said second front wall together when said coupling wall is juxtaposed with said second front wall.
