Single force strut for dual sided cargo box
First Claim
1. A spring-biased strut for a vehicular mountable cargo container having a top portion hinge-connected for pivotation relative to a bottom portion of the cargo container, said strut comprising:
- two arms operatively connected for pivotation relative to one another through a delimited range of motion;
a biasing spring operatively interposed between said two arms, said biasing spring configured to be operationally influential on said two arms during transitions between first and second strut orientations that correspond to open and closed configurations of an incorporating vehicular mountable cargo container;
said two arms being one each connectable to said top and bottom portions of the vehicular mountable cargo container thereby enabling said strut to deliver an assisting force for urging the cargo container into the open configuration;
said two arms configured relative to one another and the biasing spring so that across a substantial entirety of said delimited range of relative motion between said two arms, and which corresponds to a substantial entirety of relative motion between the top and bottom portions of the cargo container when transitioning between the open and closed configurations, the assisting force imparted to said cargo container acts in one rotational direction urging the vehicular mountable cargo container toward the open configuration;
a cam surface provided at one of said two arms, said cam surface establishing a surficial interaction between said two arms during transitions between said first and second strut orientations; and
delimiters configured to limit the range of relative motion between said two arms so that throughout the entire range of transitional motion of said strut between said first and second strut orientations, said operationally effective force imposed by said biasing spring between said two arms exclusively urges one of clockwise and counter clockwise pivotation of said cam surface including arm relative to the non-cam surface including arm.

Abstract
Methods and arrangements for providing and controlling operation of a dual sided opening roof mount cargo box for a carrying vehicle. A dual sided opening roof mount cargo box is has 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. A pair of spring-biased struts are provided, each operatively interposed between the lid portion and the bottom portion, and one each of the pair of spring-biased struts being located at the two opposite end regions of the cargo box. An expansively directed force is imposed on the lid portion, utilizing the pair of spring-biased struts, during operator induced movement from the closed configuration to the open configuration and thereby assisting the operator to smoothly open the cargo box.

4. A spring-biased strut for a vehicular mountable cargo container having a top portion hinge-connected for pivotation relative to a bottom portion of the cargo container, said strut comprising:
-
two arms operatively connected for pivotation relative to one another through a delimited range of motion; a biasing spring operatively interposed between said two arms, said biasing spring configured to be operationally influential on said two arms during transitions between first and second strut orientations that correspond to open and closed configurations of an incorporating vehicular mountable cargo container; said two arms being one each connectable to said top and bottom portions of the vehicular mountable cargo container thereby enabling said strut to deliver an assisting force for urging the cargo container into the open configuration; said two arms configured relative to one another and the biasing spring so that across a substantial entirety of said delimited range of relative motion between said two arms, and which corresponds to a substantial entirety of relative motion between the top and bottom portions of the cargo container when transitioning between the open and closed configurations, the assisting force imparted to said cargo container acts in one rotational direction urging the vehicular mountable cargo container toward the open configuration; a cam surface provided at one of said two arms, said cam surface establishing a surficial interaction between said two arms during transitions between said first and second strut orientations; and a force communication point being defined by a point of support of the non-cam surface including arm on said cam-including arm at said cam surface and which moves across the cam surface as said two arms pivot relative to one another between said first and second strut orientations during which said force communication point remains exclusively on one side of a line oriented parallel to a direction of said operationally effective force imposed by said biasing spring between said two arms and intersecting a pivot connection between said two arms. - View Dependent Claims (5)

6. A vehicular mountable cargo container comprising:
-
a top portion of said vehicular mountable cargo container hinge-connected for pivotation relative to a bottom portion of the cargo container between open and closed configurations; a pair of spring-biased struts, each operatively interposed between said top and bottom portions of said vehicular mountable cargo container, and one each of said pair of spring-biased struts located at opposed end regions of the cargo container; each of said pair of spring-biased struts being configured to exclusively deliver an assisting expansion force between the top and bottom portions of the cargo container for urging the container toward the open configuration; a cam surface provided at one of said two arms, said cam surface establishing a surficial interaction between said two arms during transitions between said first and second strut orientations; and a force communication point being defined by a point of support of the non-cam surface including arm on said cam-including arm at said cam surface and which moves across the cam surface as said two arms pivot relative to one another between said first and second strut orientations during which said force communication point remains exclusively on one side of a line oriented parallel to a direction of said operationally effective force imposed by said biasing spring between said two arms and intersecting a pivot connection between said two arms.

7. A method for providing and controlling operation of a dual sided opening roof mount cargo box for a carrying vehicle, said method comprising:
-
providing a dual sided opening roof mount cargo box having a lid portion releasably hinge-connected at two lateral sides to a bottom portion of said cargo box for alternate pivotation at each of the two lateral sides between open and closed configurations, said bottom portion being adapted to be mounted to a carrying vehicle and said lid portion being manufactured from a semi-flexible material sufficiently pliable to permit two opposite end regions thereof to be at different relative distances from the bottom portion of the cargo box during transition between the open and closed configurations; providing a pair of spring-biased struts, each operatively interposed between said lid portion and said bottom portion of said cargo box, and one each of said pair of spring-biased struts being located at said two opposite end regions of said cargo box; imposing an expansively directed force on said lid portion, utilizing said pair of spring-biased struts, across a substantial entirety of travel of said lid portion during operator induced movement from said closed configuration to said open configuration and thereby assisting the operator to smoothly open said cargo box; and controlling said expansively directed force, through configuration of said pair of spring-biased struts, to have a magnitude that substantially balances a weight of said lid portion across a range of motion of said lid portion when operating in proximity of said closed configuration. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
