- 3. A track as claimed in claim 2 wherein said housing piece and said interfitting piece form an axially extending cavity.
- 4. A track as claimed in claim 3 wherein said first flange of said interfitting piece and said second flange of said housing piece are spaced apart forming an opening to said axially extending cavity.
- 5. A track for use in a windlocking apparatus comprising a first piece and a second piece; said first piece includes at least one groove therein and said second piece includes at least one protrusion thereon; and, said protrusions of said second piece interfits said groove of said first piece locking said first and second piece together.
- 6. A track for use in a windlocking apparatus as claimed in claim 5 wherein said first and second pieces include laterally extending portions and wherein said laterally extending portions are affixed together.
- 7. A track for use as a windlocking apparatus as claimed in claim 6 wherein said first and second pieces are welded together.
- 8. A track for use as a windlocking apparatus as claimed in claim 6 wherein said first and second pieces are glued together.
- 9. A track for use as a windlocking apparatus as claimed in claim 6 wherein said first and second pieces are riveted together.
- 10. A track for use as a windlocking apparatus as claimed in claim 6 wherein said first and second pieces are screwed together.
- 11. A track for use in a windlocking apparatus as claimed in claim 5 wherein said first piece and said second piece form an axially extending cavity.
- 12. A track for use in a windlocking apparatus as claimed in claim 5 wherein said first piece includes a first flange and said second piece includes a second flange; and, said first and second flanges each have smooth contours thereon.
- 13. A track for use in a windlocking apparatus as claimed in claim 12 wherein said first flange of said first piece and said second flange of said second piece are spaced apart forming an opening to said axially extending cavity.
- 14. A windlocking apparatus for protecting a building opening comprising a first track and a second track; a flexible curtain; said flexible curtain includes first and second edges each of which include a semi-rigid strip affixed thereto; each of said tracks include a housing piece and an interfitting piece; each said housing piece and said interfitting piece are interlocked together and forming an axially extending cavity; each said axially extending cavity includes an axially extending opening therein; and, said edges of said curtain and said semi-rigid strips reside within said cavities of said tracks.
- 15. A windlocking apparatus as claimed in claim 14 wherein each of said housing pieces and said interfitting pieces of said track includes a flange thereon.
- 16. A windlocking apparatus as claimed in claim 15 wherein each of said flanges includes a smooth contour thereon.
- 17. A windlocking apparatus as claimed in claim 16 wherein said curtain seals against one of said contours on one of said flanges.
- 18. A windlocking apparatus for protecting a building opening comprising a first track and a second track; a flexible curtain; said flexible curtain includes first and second edges each of which include a semi-rigid strip affixed thereto; each of said tracks include a first piece and a second piece; each of said first pieces includes at least one groove therein and each of said second pieces includes at least one protrusion thereon; and, each of said protrusion of said second pieces interfits each of said grooves of said first piece interlocking said first and said second pieces together and forming an axially extending cavity; each said axially extending cavity includes an axially extending opening therein; and, said edges of said curtain and said semi-rigid strips reside within said cavities of said tracks.
- 19. A windlocking apparatus as claimed in claim 18 wherein each of said first and second pieces of said track includes a flange thereon.
- 20. A windlocking apparatus as claimed in claim 19 wherein each of said flanges includes a smooth contour thereon.
- 21. A windlocking apparatus as claimed in claim 20 wherein said curtain seals against one of said contours on one of said flanges.
FIELD OF THE INVENTION
[0001] This application is a continuation-in-part of co-pending application Ser. No. 09/644,924 filed Aug. 23, 2000 which is a continuation-in-part of co-pending application Ser. No. 09/520,845, filed Mar. 8, 2000. The invention is in the field of windlocking a building opening to prevent the intrusion of unwanted air, fluid (typically water or sea water) and debris During hurricanes and other high wind velocity storms, the breach of a building opening can cause great damage to the structure. If the building structure is not breached, then substantial damage can be prevented.
