A cover mechanism includes a support frame with base supports and a multi-part expandable cover engaged with the base supports by grappling members or other means. The expandable cover may have a pliable exterior cover and a set of integral ribs, the expandable cover being foldable when not deployed and being expandable to form a self-supporting structure when deployed. The base supports may provide a sliding track for the grappling members to facilitate expansion of the cover. The base supports may be adapted to rest on the ground or buoyant so that the cover can be used with watercraft. The expandable cover may be deployed by pivoting it from a folded position to an upright position, sliding the cover along the base support tracks, and pivoting the cover from the front of the base supports downwards, forming an enclosure thereby.

1. A cover mechanism, comprising: a support frame adapted to rest on a surface, said support frame having a pair of parallel base supports adapted to rest on the surface; andan expandable cover slidably coupled to the support frame, said expandable cover having a pliable exterior cover and a plurality of ribs for supporting the pliable exterior cover, and a pair of guide members disposed on a front end of said expandable cover, each guide member mechanically coupled to one or more of the ribs and hingably attached in an upright position to one of the parallel base supports when the expandable cover is in a flattened compact storage position, each guide member further comprising a latching member on a distal end thereof furthest from the surface on which the support frame rests;wherein the base supports each have a groove for guiding the expandable cover; andwherein the expandable cover is deployed from a flattened compact storage position to a fully deployed position by (i) pivoting the front end of the expandable cover from an approximately horizontal orientation until it reaches an approximately vertical orientation, whereby the guide members pivot forward causing the latching member to rotate forward in a downward arc until securably latching to the parallel base supports, (ii) sliding the front end of the expandable cover forwardly along the support frame with the guide members being guided along the grooves of the base supports, and (iii) pivoting the front end of the expandable cover downwards until it lies in proximity with the surface, thereby causing the ribs to spread apart and the pliable exterior cover to expand therebetween. 2. The cover mechanism of claim 1, wherein the cover mechanism forms a self-supporting structure when the expandable cover is fully deployed. 3. The cover mechanism of claim 2, wherein the expandable cover is tube-shaped when fully deployed, and forms a substantially completely enclosed interior. 4. The cover mechanism of claim 1, wherein the expandable cover is attached to the base supports by a plurality of grappling members. 5. The cover mechanism of claim 4, wherein the grappling members comprise hooks. 6. The cover mechanism of claim 4, wherein the grappling members slide along the length of the grooves to guide the deployment of the expandable cover. 7. The cover mechanism of claim 6, wherein the grappling members comprise a set of wheels that are slidably engaged with the base support grooves. 8. The cover mechanism of claim 1, wherein the support frame further comprises a crossbeam securably attaching the parallel base supports. 9. The cover mechanism of claim 1, wherein the expandable cover is adapted to be deployed manually. 10. The cover mechanism of claim 1, wherein the expandable cover is deployed with automated motorized assistance. 11. The cover mechanism of claim 1, wherein the pliable exterior cover is made of a fabric material, and wherein the ribs are formed of pre-formed rods having a shape corresponding to the cross-section of the cover mechanism when fully deployed. 12. The cover mechanism of claim 11, wherein the fabric material is a canvas. 13. The cover mechanism of claim 1, wherein the pliable exterior cover is made substantially of a vinyl, nylon or plastic material. 14. A cover mechanism, comprising: a support frame adapted to rest on stable medium, said support frame comprising a pair of elongate parallel base supports each having a bottom surface contacting the stable medium for providing mechanical support;an expandable cover engaged with said parallel base supports and having a pliable exterior cover and a plurality of ribs integral therewith, the expandable cover being foldable when not deployed and being expandable to form a self-supporting structure when deployed, wherein the ribs align uniformly in a straight line along a single groove in each of the parallel base supports when the expandable cover is deployed;a lead screw having an elongate shaft extending along a length of one of the base supports; anda guide member attached to the expandable cover and pivotally engaged with said one of the base supports, the guide member having a latching member that is disengaged when the expandable cover is not deployed and latched when the expandable cover is deployed, the guide member being slidably engaged with the lead screw such that when the lead screw rotates either direction, the guide member moves in a corresponding direction along the shaft of the lead screw and thereby forward or backward along the base support, the forward motion of the guide member causing the expandable cover to deploy first from a flat horizontal position to an upright position and then to expand horizontally along the length of the base support. 15. The cover mechanism of claim 14, further comprising a manually rotatable crankshaft mechanically engaged with the lead screw for rotating the lead screw in order to deploy the expandable cover. 16. The cover mechanism of claim 14, wherein the support frame further comprises a crossbeam adapted to rest flush with the stable surface across its length and securably attaching the parallel base supports. 17. The cover mechanism of claim 14, wherein the expandable cover is adapted to be deployed manually. 18. The cover mechanism of claim 14, wherein the pliable exterior cover is made of a fabric material, and wherein the ribs are formed of pre-formed rods having a shape corresponding to the cross-section of the cover mechanism when fully deployed. 19. The cover mechanism of claim 14, wherein the pliable exterior cover is made substantially of a vinyl, nylon, or plastic material.
