Abstract:
A tube segment for use with other identical tube segments to create a tube system for pets, the tube segment comprising:a. a first hollow truncated sphere having an outer surface and an inner surface;b. a second hollow truncated sphere having an outer surface and an inner surface;c. the radius of curvature of said inner surface of said second hollow truncated sphere being slightly greater than the radius of curvature of said outer surface of said first hollow truncated sphere;d. a narrow, hollow, annular waist section having a concave outer surface and a convex inner surface;e. said first and second hollow truncated spheres being joined together by said narrow, hollow, annular waist section with said outer surfaces of said first and second hollow truncated spheres merging smoothly with said outer concave surface of said narrow, hollow, annular waist section and said inner surfaces of said first and second hollow truncated spheres merging smoothly with said inner convex surface of said narrow, hollow, annular waist section, thereby forming a tubular element of hour-glass configuration having said first hollow truncated sphere as one end portion thereof, said second hollow truncated sphere as the other end portion thereof, and said narrow, hollow, annular waist section as the mid section thereof;f. said first and second hollow truncated spheres each terminating in an annular peripheral end edge remote from said narrow, hollow, annular waist section; and,g. said first hollow truncated sphere having a plurality of tapered slots formed therein extending from said outer surface to said inner surface, each said tapered slot beginning at said annular peripheral edge of said first hollow truncated sphere and converging toward said narrow, hollow, annular waist section.
