초록 ▼

A lockable pipe cover includes an inner cap and an outer cover which are selectively coupled together for axial rotation. When the cap is locked, the inner cap and the outer cover are free to rotate independently from one another thus rotation of the outer cover will not remove the cap from the pipe. In the unlocked position, the inner cap and the outer cover are coupled for rotation and thus rotation of the outer cover results in rotation of the inner cap.

1. A lockable pipe cap comprising: an inner cap comprising a portion of a pipe closure comprising an outer surface;an outer cover covering substantially all of said outer surface of said inner cap;said inner cap and said outer cover being selectively coupled by an axially translatable traveler, said traveler axially translatable between at least a first unlocked position and a second locked position;said traveler being movable between said first position and said second position by a lead screw, said lead screw being rotatable by an exposed end of said lead screw, and said exposed end being accessible from an outer surface of said lockable cap;said traveler being engaged with both said inner cap and said outer cover when in said first unlocked position such that rotation of said outer cover can be used to thread said inner cap onto a pipe to be closed by said lockable pipe cap; andsaid traveler being engaged with only one of said inner cap and said outer cover when in said second locked position such that said inner cap and said outer cover are independently rotatable when said traveler is in said second unlocked position and such that said lockable pipe cap cannot be removed from the pipe to be closed by rotating said outer cover. 2. The lockable cap of claim 1, wherein said traveler is located between said inner cap and said outer cover. 3. The lockable cap of claim 2, wherein said traveler is configured to span a gap between said inner cap and said outer cover in said first unlocked position. 4. The lockable cap of claim 1, wherein said traveler threadably engages said lead screw. 5. The lockable cap of claim 1, wherein said inner cap is internally threaded such that said inner cap can be threaded onto the pipe to be closed by said lockable pipe cap. 6. The lockable cap of claim 1, wherein said outer cover defines a hole through which said lead screw is accessible by a key wrench. 7. The lockable cap of claim 1, wherein ribs are provided on an outer surface of said outer cover. 8. The lockable cap of claim 1, wherein said lead screw is located on a central axis of said cap. 9. The lockable cap of claim 1 further comprising a gasket mounted to a rearwardly facing surface of said inner cap. 10. The lockable cap of claim 1 further comprising a biasing component mounted between said traveler and said outer cover. 11. The lockable cap of claim 10 further comprising a locking washer configuration positioned between a head of said lead screw and said outer cover. 12. The lockable cap of claim 1, wherein said outer cover comprises a generally cylindrical outer wall and an end wall, said end wall comprising a protruding boss. 13. The lockable cap of claim 1, wherein said outer cover comprises one or more gripping structures. 14. The lockable cap of claim 1, wherein said outer cover comprising a side wall and an end wall, said outer cover defining an inner chamber and said end wall having an inner surface that faces said inner chamber, said traveler and said inner chamber being positioned within said inner chamber, and a recess being defined on said inner surface of said end wall, said recess being configured to receive at least a portion of said traveler. 15. The lockable cap of claim 14, wherein said recess comprises an undulating side wall that defines multiple lobes about a periphery of said recess. 16. The lockable cap of claim 14, wherein a détente mechanism is positioned between said traveler and at least one of said inner cap and said outer cover. 17. The lockable cap of claim 16, wherein said détente mechanism is positioned between said traveler and said inner cap. 18. The lockable cap of claim 17, wherein said détente mechanism comprises a biased ball and that is selectively received within any of a plurality of recesses defined within said inner cap. 19. The lockable cap of claim 17, wherein said détente mechanism comprises one or more springs that extend through at least a portion of said traveler. 20. The lockable cap of claim 1 further comprising a friction-reducing washer that is positioned between a face of said inner cap and an opposing face of said outer cover.
