Modular equipment case with sealing system

摘要

A container includes a sealing system coupled to an interior surface of the container's lid or cover. The sealing system includes a rotatable latch that, when rotated, cooperates with a number of gears to and a cam assembly formed in the lid to actuate a number of arms or links. In one embodiment, some of the arms extend approximately radially from a driven gear and operate to move an engagement member of the sealing assembly into contact with a complementary engagement member coupled to a base portion of the container. This engagement, in turn, compresses a seal or gasket located between the lid portion and the base portion of the container.

主权项

1. An equipment container comprising:
a base portion forming a containment space to receive equipment; a molded lid portion coupleable to the base portion, the molded lid portion having a plurality of guide channels; and a sealing system located proximate an interior surface of the molded lid portion, the sealing system comprising:
a rotatable latch coupled to a drive gear;a driven gear engaging the drive gear;a linkage assembly having first links pivotally coupled to the driven gear and second links each having first end portions pivotally coupled to the respective first links and second end portions received by the respective guide channels, wherein the guide channels define a travel path for the second end portions, the linkage assembly further having movable internal latch mechanisms coupled to the second end portions of the second links, the movable internal latch mechanisms operable to sealingly compress a seal located between the base portion and the molded lid portion with a desired amount of rotation applied to the rotatable latch, wherein the sealing system moves between an open state and a closed state as the second end portions along the travel path; anda cam assembly including a plurality of sloped surfaces configured to guide a respective plurality of cam followers coupled to the linkage assembly, the driven gear defining a central aperture, the cam assembly being positioned within the central aperture.
