Container with gravity releasable locking lids

摘要

A container can include a body having an opening, a lid for selectively covering the opening, and a lock system for securing the lid. The lock system can include a limiter slidably mounted on a pivot pin between first and second latch members and configured to engage and control rotation of the first and second latch members. The limiter can be weighted such that when the container is upright the limiter is biased by gravity towards a pivot pin when the first and second latch members engage a lock pin and prevent the first and second latch members from disengaging the lock pin.

主权项

1. A container comprising:
a body having a wall defining an interior and an opening to the interior at a top of the body; a lid pivotally coupled to the top of the body for selectively covering the opening; and a lock system for selectively securing the lid to the container, the lock system comprising: a pivot pin mounted to the lid; a lock pin mounted on the body adjacent to the opening and generally vertically aligned with the pivot pin when the container is upright; a first latch member pivotally mounted on the pivot pin and configured to engage the lock pin from a first side thereof; a second latch member pivotally mounted on the pivot pin and configured to engage the lock pin from a second side thereof opposite the first side; and a limiter slidably mounted on the pivot pin between the first and second latch members and configured to engage and control the rotation of the first and second latch members, the limiter weighted such that when the container is upright the limiter is biased by gravity towards the pivot pin when the first and second latch members engage the lock pin to prevent the first and second latch members from disengaging the lock pin; each of the first and second latch members comprising a latch body having a recess sized to receive the lock pin to prevent opening of the lid when the latch members engage the lock pin, and a bottom surface shaped to pivot each latch member away from the lock pin when each latch body contacts the lock pin as the lid closes.
