A container pedestal for supporting and securing a cargo container having a catch opening on a vehicle such as a rail car. The pedestal includes a base defining a platform for supporting the container. A pivotal latch lever is biased by a spring into a latched position wherein a latching nose on the lever registers with a latch recess in the container. The latch nose is contacted by the container for pivoting the latch lever from the latched to a released position when the container is raised or lowered. The latch lever is mounted for vertical movement as well as pivotal movement, and interfacing locking surfaces are provided on the latch lever and on the pedestal base for preventing pivotal movement of the latch lever out of the latched position when the latch lever is in an upper position. The spring biases the latch lever upwardly to maintain the locking surfaces normally in engagement so that, when the latch lever is in its upper position, the container cannot pivot the latch lever. If a container is lowered into the pedestal with the latch lever in the upper position, the container moves the latch lever downwardly to separate the locking surfaces and permit the latch lever to pivot to the released position for automatic loading of the container. A cam is selectively operable to hold the latch lever in its lower position wherein the locking surfaces are separated and the latch lever can be pivoted by upward or downward movement of a container. A line contact between the latch lever and the spring provides a uniform spring lever arm length.
A container pedestal for a cargo container which is lowered onto and lifted from the pedestal, the container having a latch recess, said container pedestal comprising:
A container pedestal for the releaseable securement of a cargo container having a catch opening, said pedestal comprising a base defining a container receiving platform, a latch lever, pivotal mounting means supporting the latch lever for pivotal movement between latched and released positions, said latch lever having a nose portion receivable into the container catch opening for securing the container on said platform, said nose portion being engageable by the container upon raising and lowering of the container for pivoting the latch lever to the released position, spring means biasing said latch lever toward the latched position, cooperating locking structures on said latch lever and on said base inter-engageable with one another to prevent pivotal movement of said latch lever from the latched position;
In a container pedestal of the type including a base defining a platform for supporting a cargo container lowered onto the platform and including a pivotal latch lever biased into a latched position by a spring acting between the base and the lever, the lever including a latching nose registering with a latch recess in the container for holding the container on the platform, the latch nose being contacted by the container for pivoting the latch lever from the latched to a released position, the improvement comprising:
A container pedestal for the releaseable securement of a cargo container having a catch opening, said pedestal comprising a base defining a container receiving platform, a latch member, mounting means supporting the latch member for movement in a first direction between latched and released positions, said latch member having a nose portion receivable into the container catch opening for securing the container on said platform, said nose portion being engageable by the container upon raising and lowering of the container for moving the latch member in said first direction to the released position, spring means biasing said latch member toward the latched position, cooperating locking structures on said latch member and on said base inter-engageable with one another to prevent movement of said latch member in said first direction from the latched position;
A container pedestal for the releaseable securement of a cargo container having a catch opening, said pedestal comprising:
