Abstract
A cover for covering elbows or angles in tubular conduits formed in the shape of a convoluted sheet of material such as polyethelene, and shaped to form a first stable configuration state fitting part way around the object to be covered. Opposite ends of the cover are caused to encircle the selected portion of the object in a second stable configuration state. In other embodiments, the cover has an integral part thereof, coupling ribs, adhesive, a tongue-in-sleeve or belt-in-loop arrangement or other coupling means or combinations of coupling means by which two opposite ends of the cover are coupled together around an object.
Claims4
An elbow cover formed from a flexible, thin-sheet structure, comprising:
- first and second cylindrical surface sections, each conformed transversely to approximate a peripheral arc of a first semicircle, said first and second surface sections each further including first longitudinally extending joining edges formed on either side thereof;
- a first toroidal arc section conformed radially to approximate said peripheral arc of said first semicircle connected between the adjacent transverse ends of said first and second cylindrical surface sections;
- third, fourth, fifth and sixth cylindrical surface sections conformed transversely to approximate peripheral arc of a second semicircle, each said third, fourth, fifth and sixth surface sections including second longitudinal joining edges joined to the respective longitudinal joining edges of said first and second surface sections;
- and
- second and third toroidal oppositely disposed arc sections conformed radially to approximate the peripheral arc of said second semicircle, connected between the respective adjacent transverse ends of said third and fourth, and fifth and sixth surface sections and including an elliptic deformation formed over the central section thereof.
