<p>A twist lock for connecting containers comprises a housing integrally formed with an upper fitting part and a lower fitting part each being capable of fitting into a fitting hole in a corner fitting of a container, a spindle inserted in the housing in a rotatable and vertically displaceable manner, an upper lock connected to the top end of the spindle and being engageable with the fitting hole in the corner fitting of the container, and a lower lock being in positional agreement with and fixed securly to the lower fitting part of the housing and slidably fitted with a plurality of locking members which can engage with and disengage from the fitting hole in the corner fitting of the container. In this twist lock, the spindle is urged by a spring member in such a direction that the upper lock can engage with the fitting hole in the corner fitting of the container, while each of the locking members is urged by another spring member in such a direction that it can retract into the lower lock. When the spindle locates at a lowered position, the locking members contact the spindle and project from the lower lock against the urging force of the spring means, thereby engaging with the fitting hole in the corner fitting of the container to prevent the release of the lower lock. When the spindle locates at a raised position, the locking members lose contact with the spindle and retract into the lower lock by the urging force of the spring means, thereby disengaging from the fitting hole in the corner fitting of the container to permit the release of the lower lock. <IMAGE></p> |
