Container locking systems

Abstract

A system for locking a container door to a container body is provided. The system includes a rotating member coupled to the door. The system further includes a cover covering the rotating member and an opening formed through the cover. The system also includes a handle coupled to the rotating member and extending though the opening, the handle being moveable through the opening for rotating the rotating member between a locked and an unlocked position. Moreover the system includes a lock for preventing rotation of the rotating member to the unlocked position.

1 . A lock system for locking a container door to a body of a container comprising:
 a rotating member coupled to the door and interfacing with a member extending from the body of the container, wherein rotation of the rotating member about a longitudinal axis of said rotating member in a first direction causes the rotating member to rotate to a first position to lock with the member, and rotation about a second direction opposite the first direction causes the rotating member to rotate to a second position to unlock from the member;   a longitudinal cover extending over a majority of the rotating member;   an opening formed through the cover;   a handle coupled to the rotating member and extending though the opening, said handle being moveable across the opening for rotating said rotating member in the first and second directions; and   a lock locking onto the handle, said lock having a surface interfacing with the opening for preventing rotation of the rotating member to the second position.   
   
   
       2 . The system as recited in  claim 1  wherein the cover extends along the entire length of the rotating member. 
   
   
       3 . The system as recited in  claim 1  wherein the cover extends over the rotating member and the member extending from the body of the container. 
   
   
       4 . The system as recited in  claim 3  further comprising a cap covering an end of said cover proximate said member extending from the body of the container. 
   
   
       5 . The system as recited in  claim 1  wherein the opening is bounded at least in part by an opening wall extending generally perpendicular in relation to the rotating member for being engaged by said lock surface thereby interfacing with said opening for preventing rotation of the rotating member to the second position. 
   
   
       6 . The system as recited in  claim 5  wherein the opening wall defines a generally circular section and wherein the lock is generally circular and wherein said lock surface is a peripheral surface of said lock. 
   
   
       7 . The system as recited in  claim 6  further comprising a bar extending from the handle, wherein the lock interlocks with said bar. 
   
   
       8 . The system as recited in  claim 1  wherein the handle comprises:
 a first handle portion coupled to the rotating member;   a bracket coupled to the first handle portion, said bracket extending outside of the cover during operation of the handle; and   a handle arm coupled to the bracket.   
   
   
       9 . The system as recited in  claim 1  wherein the handle comprises a section extending outside the cover designed to break prior to a remaining portion of the handle when exposed to a force. 
   
   
       10 . The system as recited in  claim 1  wherein the cover comprises two parallel walls extending from the door and a transverse wall there between defining a box like structure with the door. 
   
   
       11 . The system as recited in  claim 1  wherein the cover is a box structure comprising four walls. 
   
   
       12 . The system as recited in  claim 1  wherein the cover in combination with the door and said perimetral portion of the contain encapsulate the rotating member and the member extending from the body of the container when said door is in a closed position. 
   
   
       13 . A system for locking a container door to a body of a container comprising:
 a rotating member coupled to the door for interfacing with a member extending from the body of the container, wherein rotation of the rotating member about a longitudinal axis in a first direction causes the rotating member to rotate to a first position for locking with the member extending from said body, and rotation about a second direction opposite the first direction causes the rotating member to rotate to a second position for unlocking from the member extending from said body;   a longitudinal cover extending over a majority of the rotating member;   an opening formed through the cover; and   a handle coupled to the rotating member and extending though the opening, said handle being moveable through the opening for rotating said rotating member in the first and second directions.   
   
   
       14 . The system as recited in  claim 13  further comprising a lock for preventing rotation of the rotating member to the second position. 
   
   
       15 . The system as recited in  claim 14  wherein said lock engages the cover when the handle is being moved toward the second position for preventing rotation of the rotating member to the second position. 
   
   
       16 . The system as recited in  claim 14  further comprising a bar mounted on the door, wherein the lock engages said bar for preventing rotation of the rotating member to the second position. 
   
   
       17 . The system as recited in  claim 16  wherein said lock engages the cover when the handle is being moved toward the second position for preventing rotation of the rotating member to the second position. 
   
   
       18 . The system as recited in  claim 16  wherein the handle comprises an opening penetrated by said bar when the rotating member is in the first position. 
   
   
       19 . The system as recited in  claim 16  wherein the lock is generally circular in plan view and wherein the opening formed through the cover comprises a circular portion, wherein said lock is concentric with and occupies said circular portion. 
   
   
       20 . The system as recited in  claim 14  wherein the lock is generally circular in plan view and wherein the opening formed through the cover comprises a circular portion, wherein said lock is concentric with and occupies said circular portion. 
   
   
       21 . The system as recited in  claim 14  wherein the opening is bounded at least in part by a peripheral wall and wherein said lock engages said peripheral wall for interfacing with the cover for preventing rotation of the rotating member to the second position. 
   
   
       22 . The system as recited in  claim 13  wherein the cover extends along the entire length of the rotating member. 
   
   
       23 . The system as recited in  claim 13 , wherein said cover is designed for also extending over said member extending from the body of the container when the door is closed. 
   
   
       24 . The system as recited in  claim 13  further comprising a cap covering an end of said cover, said cap positioned for extending above said member extending from the body of the container when the door is closed. 
   
   
       25 . The system as recited in  claim 13  wherein the handle comprises:
 a first handle portion coupled to the rotating member;   a bracket coupled to the first handle portion, said bracket extending outside of the cover during operation of the handle; and   a handle arm coupled the bracket.
