Description:
BACKGROUND OF THE INVENTION 
     Pick-up trucks are typically produced with a cargo box having an open design with a tailgate which may be lowered or opened in some manner to allow access to the cargo box. Presently, there are many options and styles provided through the aftermarket to cover the open box to keep contents placed in the box out of the weather, more secure, or just to provide a more pleasing aesthetic. Varieties of box covers include both soft and hard tonneau covers and paneled tonneau covers which extend across the top of the box at the height of the box rails, and caps (or toppers) which sit on top of the box rails and extend over the box at a height of at least the height of the truck cab. Although some soft and paneled covers offer the ability to roll or remove the cover material entirely, the intended utility of the cover is typically limited to the dimensions defined by the cover itself. 
     Therefore, there is a need for a box cover that can transform to suit multiple load types and still protect the load from outside elements. 
     SUMMARY OF THE INVENTION

     The rack system  300  is configured to be incorporated and usable with both cover system  100 , 200  in both the first position and the second position.  FIGS. 18-20  illustrate thus with the cover system  100 . 
     A method for raising and lowering a truck box cover is also contemplated according to the present invention and is describes with respect to the first embodiment of the truck box cover assembly  100 . The method preferably comprises the steps of: providing a first frame  102  and a second frame  124 ; providing a plurality of telescopic assemblies  192  operably connected to the first frame  102  and the second frame  124 , whereby the second frame  124  is configured to be movable relative to the first frame  102  through activation of the plurality of telescopic assemblies  192  between two positions: a first position and a second position; whereby in the first position the first frame  102  and the second frame  124  are juxtaposed and in the second position the first frame  102  and the second frame  124  are spaced apart; providing a first compliant member  160  supported by and extending across the second frame  124 ; providing a second compliant material  170  supported by and extending between the first frame  102  and the second frame  124 ; whereby, when in the first position, activating the plurality of telescoping assemblies  192  to move the second frame  124  to the second position wherein the second compliant material  170  is taut; and whereby when in the second position, activating the plurality of telescoping assemblies  192  to move the second frame  124  to the first position. The method further comprises the step of actively monitoring the truck box cover system  100  when moving from the second position to the first position. Active monitoring may include, but should not be limited to, constantly maintained activation of the plurality of telescopic assemblies  192  by a user (not shown) and/or pressure sensors (not shown) monitoring force applied in a direction different than the downward movement of the second frame  124 . The method may further comprise the step of tucking the second compliant member  170  into a first rail member retainer  112  and a second rail member enclosure  118  of the first frame  102  when moving the second frame  124  from the second position to the first position. 
     The foregoing is considered as illustrative only of the principles of the invention. Furthermore, because numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
