1. An expandable street curb inlet filter for filtering debris flowing into a street curb inlet having a top and a base, comprising: a. a rigid frame strut having a first guided sleeve pivotally attached on a first end and rigidly connected at a second end to a first extended rod;b. a rigid compression strut pivotally connected at a first end at a point between the first and second end of said rigid frame strut and fixedly connected at its second end to a second extended rod;c. a second guided sleeve pivotally attached between said first end and said second end of said rigid compression strut; said second guided sleeve fixedly attached to a threaded nut;d. a threaded fastener passing through said first guided sleeve and said threaded nut of said second guided sleeve;e. a filter medium attached fixedly between said first and second extended rods;f. wherein said threaded fastener, when tightened, moves said rigid compression strut upwards in a reverse scissor movement to separate said first and second extended rods and deploy said filter medium and seal said first and second rods against said top and base of said street curb inlet. 2. The expandable street curb inlet filter of claim 1 wherein said filter medium comprises a landscape fabric. 3. The expandable street curb inlet filter of claim 1 wherein said filter medium comprises a wire mesh fabric. 4. The expandable street curb inlet filter of claim 1 wherein said first and second extended rods are metallic. 5. The expandable street curb inlet filter of claim 1 wherein said first and second extended rods are hardened polymers. 6. An expandable street curb inlet filter for filtering debris flowing into a street curb inlet having a top and a base, comprising: a. a rigid frame strut having a first guided sleeve pivotally attached on a first end and fixedly connected at a second end to a first extended rod;b. a rigid compression strut pivotally connected at a first end at a point between the first and second end of said rigid frame strut and fixedly connected at its second end to a second extended rod;c. a second guided sleeve pivotally attached between said first end and said second end of said rigid compression strut;d. a threaded turnbuckle assembly connected to said first guided sleeve and said second guided sleeve;e. a filter medium attached fixedly between said first and second extended rods;f. wherein said threaded turnbuckle assembly, when tightened, moves said rigid compression strut upwards in a reverse scissor movement to separate said first and second extended rods and deploy said filter medium and seal said first and second rods against said top and base of said street curb inlet. 7. The expandable street curb inlet filter of claim 6 wherein said filter medium comprises a landscape fabric. 8. The expandable street curb inlet filter of claim 6 wherein said filter medium comprises a wire mesh fabric. 9. The expandable street curb inlet filter of claim 6 wherein said first and second extended rods are metallic. 10. The expandable street curb inlet filter of claim 6 wherein said first and second extended rods are hardened polymers. 11. An expandable street curb inlet filter for filtering debris flowing into a street curb inlet having a top and a base, comprising: a. a rigid frame strut having a first guided sleeve pivotally attached on a first end and rigidly connected at a second end to a first extended rod; said first guided sleeve fixedly attached to a threaded nut;b. a rigid compression strut pivotally connected at a first end at a point between the first and second end of said rigid frame strut and fixedly connected at its second end to a second extended rod;c. a second guided sleeve pivotally attached between said first end and said second end of said rigid compression strut;d. a threaded fastener passing through said second guided sleeve and said threaded nut of said first guided sleeve;e. a filter medium attached fixedly between said first and second extended rods;f. wherein said threaded fastener, when tightened, moves said rigid compression strut upwards in a reverse scissor movement to separate said first and second extended rods and deploy said filter medium and seal said first and second rods against said top and base of said street curb inlet. 12. The expandable street curb inlet filter of claim 11 wherein said filter medium comprises a landscape fabric. 13. The expandable street curb inlet filter of claim 11 wherein said filter medium comprises a wire mesh fabric. 14. The expandable street curb inlet filter of claim 11 wherein said first and second extended rods are metallic. 15. The expandable street curb inlet filter of claim 11 wherein said first and second extended rods are hardened polymers. 16. A method for filtering debris flowing into a street curb inlet having a top and a base, comprising the steps of: a. providing a rigid frame strut having a first guided sleeve pivotally attached on a first end and fixedly connected at a second end to a first extended rod;b. providing a rigid compression strut pivotally connected at a first end at a point between the first and second end of said rigid frame strut and fixedly connected at its second end to a second extended rod;c. providing a second guided sleeve pivotally attached between said first end and said second end of said rigid compression strut;d. providing a filter medium attached fixedly between said first and second extended rods;e. providing a driving force that moves said rigid compression strut upwards in a reverse scissor movement to separate said first and second extended rods and deploy said filter medium and seal said first and second rods against said top and base of said street curb inlet. 17. The method for filtering debris flowing into a street curb inlet having a top and a base of claim 16 wherein said second guided sleeve is fixedly attached to a threaded nut; and wherein a threaded fastener passes through said first guided sleeve and said threaded nut of said second guided sleeve; and wherein the driving force that moves said rigid compression strut upwards in a reverse scissor movement is provided by tightening the threaded fastener. 18. The method of filtering debris flowing into a street curb inlet having a top and a base of claim 16 wherein said first guided sleeve is fixedly attached to a threaded nut; and wherein a threaded fastener passes through said second guided sleeve and said threaded nut of said first guided sleeve; and wherein the driving force that moves said rigid compression strut upwards in a reverse scissor movement is provided by tightening the threaded fastener.
