A vehicular roof rack system has a cross bar that employs a base member, a top member that is retractable to a position within the base member, a spring for biasing the top member away from the base member, and a spring case encompassing the spring to limit spring extension and thus protraction of the top member. The spring case is a two-piece case within which the spring biases against the base member when the top member is in its stowed position to place the top member in its protracted position. The top member and the base member fit together in the retracted position to form an aerodynamic part to permit the cross bar to reduce drag and wind noise when moved through a medium. When protracted, the top member and the bottom member define a gap therebetween so that cargo to be secured can be tied to the top member.

What is claimed is: 1. A roof rack comprising: a base member defining a recession; a top member that is retractable to a first position within the recession defined by the base member; and a spring, a first end of which is connected to and perpendicular to the base member and a second end of which
What is claimed is: 1. A roof rack comprising: a base member defining a recession; a top member that is retractable to a first position within the recession defined by the base member; and a spring, a first end of which is connected to and perpendicular to the base member and a second end of which is connected to and perpendicular to the top member, wherein the spring biases the top member away from the base member, the base member further including a rod cavity; the top member further including a latch cavity opening into the rod cavity and having a latching surface therein; a release rod positioned in the rod cavity for longitudinal movement therein; and a latching element coupled to the release rod and extending into the latch cavity, the latch element carrying a latch operative to engage the latching surface in a first longitudinal position of the release rod wherein the spring is compressed, and operative to clear the latching surface in a second longitudinal position of the release rod wherein the spring is extended. 2. The roof rack of claim 1, further comprising a spring casing that encompasses the spring to limit extension of the spring and protraction of the top member, wherein the spring case is flexible. 3. The roof rack of claim 1, wherein the spring is encapsulated by a spring case that limits the amount of protraction of the top member. 4. The roof rack of claim 1, wherein the base member has a leading surface that has a slope that is different than a slope of a trailing surface, with respect to a bottom surface of the base member. 5. The roof rack of claim 1, wherein the top member and the base member define a gap therebetween when the top member is in its protracted position. 6. A cargo rack for an automobile comprising: a base member having a flat bottom surface and a rod cavity; a top member that is retractable to a first position within the base member and protractable to a second position such that the top member disengages the base member and forms a gap therebetween, the top member further including a latch cavity opening into the rod cavity and having a latching surface therein; a spring for biasing the top member away from the base member, wherein the spring biases against the base member to move the top member from a stowed position toward a protracted position; a spring case encompassing the spring, the spring case limiting extension of the spring and protraction of the top member; and a release rod, wherein the release rod is releasably engaged by the latch surface and an end of the release rod is coupled to a push button which effects movement of the release rod into and out of engagement with the latch surface. 7. The cargo rack of claim 6, wherein the top member has a curved outer periphery. 8. The cargo rack of claim 7, the base member further comprising: a first angled flat surface proximate to a leading surface of the base member; a second angled flat surface proximate to a trailing surface of the base member; and a flat surface that is parallel to the flat bottom surface, wherein the first and second angled flat surfaces intersect the flat surface. 9. The cargo rack of claim 8, the top member further comprising: a front angled flat surface, a rear angled flat surface, and a bottom flat surface, each respectively contacting the first angled flat surface, the second angled flat surface and the bottom flat surface of the base member when the top member is in its retracted position within the base member. 10. The cargo rack of claim 9, wherein the spring case is flexible. 11. The cargo rack of claim 10, wherein the leading surface of the base member has a slope that is different than a slope of the trailing surface with respect to a bottom surface of the cross bar. 12. The roof rack of claim 1 further comprising an actuator coupled to one end of the release rod for effecting movement of the release rod between the first and second positions. 13. The roof rack of claim 12 wherein the actuator comprises a spring-biased push button. 14. The roof rack of claim 1 wherein the base member and the top member are elongated elements adapted to be placed on a vehicle roof so as to extend from one lateral side of the vehicle roof to an opposite lateral side of the vehicle roof and wherein the rod cavity of the base member extends substantially throughout a length of the base member and wherein the top member includes a plurality of latch cavities each opening into the rod cavity, each having a latching surface therein; each carrying a latching element coupled to the release rod and extending into the latch cavity, each latching element carrying a latch for engagement with and release from a corresponding latching surface in accordance with longitudinal positions of the release rod. 15. The roof rack of claim 14 further comprising an actuator coupled to one end of the release rod for varying longitudinal positions thereof. 16. The roof rack of claim 15 wherein the actuator comprises a spring-biased push button.
