Abstract

A retractable canopy and supporting structure for mounting onto the load bed of a vehicle wherein the supporting structure may be selectively slid along longitudinally extending guide rails on opposite sides of the load bed and wherein the primary supporting structure is sufficiently stable so as to resist one side of the primary support structure member from sliding along its corresponding guide rail without there being corresponding sliding movement of the opposite end of the primary structure member on the opposite guide rail when the primary structure member is urged longitudinally along the guide rails from only one side of the load bed, and wherein when the canopy is deployed over the load bed and the primary structure latched to the rearmost end of the load bed, the canopy is maintained taut over the supporting structure by resilient springs mounting the forward end of the canopy to the forward end of the load bed or to the vehicle cab.

A retractable vehicle canopy for a vehicle, said retractable vehicle canopy comprising:

a pair of guide means mountable longitudinally in parallel opposed relation on opposite sides of a vehicle load bed so as to extend said guide means longitudinally in a first direction along said load bed,
a carriage member releasably mountable into sliding engagement with said guide means so as to extend said carriage member laterally across said load bed in a second direction, perpendicular to said first direction, between said pair of guide means extending longitudinally in said first direction,
said carriage member comprising a hoop member rigidly mounted to and extending between carriage shoes mounted to opposite ends of said hoop member, said carriage shoes releasably mountable into sliding engagement along said guide means, said carriage shoes comprising sliding pressure transfer means for applying a first force vertically downward from said hoop member onto upper bearing surfaces on said guide means, and a second force generally horizontally inwards in said second direction against corresponding lateral bearing surfaces on said guide means, said hoop member having a flexed lateral dimension in said second direction when measured between opposed ends of said hoop member, when releasably mounted in sliding engagement with said guide means, that is greater than a non-flexed lateral dimension measured between said opposed ends of said hoop member when said hoop member is removed from said guide means, wherein said hoop member is resiliently spreadable between a non-flexed position and a flexed position corresponding to said non-flexed dimension and said flexed dimension respectively, whereby said hoop member may be spread laterally outwardly in said second direction for releasable slidable mounting of said carriage shoes into sliding engagement with said guide means,
a flexible canopy releasably mountable at a rear edge thereof to said carriage member and at a forward edge thereof to said vehicle whereby when said carriage is slid along said guide means in said first direction said canopy may be deployed over said load bed or retracted so as to uncover said load bed, said carriage member releasably latchable by latching means to a rearmost end of said load bed,
said hoop member sufficiently rigid so as when in said flexed position, said carriage shoes are releasably mountable into sliding engagement with said guide means, and said second force is thereby applied against said corresponding lateral bearing surfaces on said guide means, and wherein said carriage shoes have a longitudinal dimension in said first direction when releasably mounted into sliding engagement on said guide means so as to stabilize said hoop member in relation to said guide means and to equally distribute said second force along said corresponding lateral bearing surfaces on said guide means.
