Claim Text:
1. A dual sided opening roof mount cargo box for a carrying vehicle comprising: a lid portion releasably hinge-connected at two lateral sides to a bottom portion of the cargo box for alternate pivotation at each of the two lateral sides between open and closed configurations, the bottom portion being adapted to be mounted to the carrying vehicle; a pair of spring-biased struts, each operatively interposed between the lid portion and the bottom portion of the cargo box, and one each of the pair of spring-biased struts being located at two opposite end regions of the cargo box; and each of the pair of spring-biased struts comprising two arms operatively interconnected for pivotation relative to one another through a delimited range of motion, the two arms having a biasing spring operatively interposed therebetween, the biasing spring configured to operatively influence the two arms during transition between first and second strut orientations that respectively correspond to closed and open configurations of the cargo box, wherein the pair of spring-biased struts is configured to control an assisting force that urges the cargo box into the open configuration to have a magnitude that substantially balances a weight of the lid portion thereby facilitating an operator's even lifting of the lid portion across the delimited range of motion of the two arms, wherein the pair of spring-biased struts is configured to control the assisting force to have a substantially zero magnitude when the lid portion is in the closed configuration.
