Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
244 words
In combination, a coupling device comprising a molded substantially tubular shaped plastic body and a thin plastic tubing having a substantially smaller inside and outside diameter than said tubular shaped plastic body, one end of said tubular shaped plastic body being secured to an air-delivering member and having an internal diameter smaller than the external diameter of said air-delivering member when in its unstressed condition, said one end of said tubular shaped body being deformed by said airdelivering member when secured thereto to provide the sole means of securement between said air-delivering member and said tubular shaped body, a metal air-conveying member having a flanged collar at one end thereof, said flanged collar being disposed within said tubular shaped body and positionally secured therewithin at the other end thereof, the other end of said metal air-conveying member being disposed outwardly of said tubular shaped body, the inside diameter of said tubing being smaller than the outside diameter of said metal air-conveying member when in its unstressed condition, one end of said tubing being deformed by the other end of said metal air-conveying member when secured thereto to provide the sole means of securement between said respective ends, the other end of said tubing being slidably engageable to a member to which said tubing is to be coupled, and wherein the ratio of the internal diameter of said tubular shaped body to the inside diameter of said plastic tubing is greater than 3 to 1.
Claim 2
Dependent Claim
244 words
In combination, a coupling device comprising a molded substantially tubular shaped plastic body and a thin plastic tubing having a substantially smaller inside and outside diameter than said tubular shaped plastic body, one end of said tubular shaped plastic body being secured to an air-delivering member and having an internal diameter smaller than the external diameter of said air-delivering member when in its unstressed condition, said one end of said tubular shaped body being deformed by said airdelivering member when secured thereto to provide the sole means of securement between said air-delivering member and said tubular shaped body, a metal air-conveying member having a flanged collar at one end thereof, said flanged collar being disposed within said tubular shaped body and positionally secured therewithin at the other end thereof, the other end of said metal air-conveying member being disposed outwardly of said tubular shaped body, the inside diameter of said tubing being smaller than the outside diameter of said metal air-conveying member when in its unstressed condition, one end of said tubing being deformed by the other end of said metal air-conveying member when secured thereto to provide the sole means of securement between said respective ends, the other end of said tubing being slidably engageable to a member to which said tubing is to be coupled, and wherein the ratio of the internal diameter of said tubular shaped body to the inside diameter of said plastic tubing is greater than 3 to 1.
Claim 3
Dependent Claim
43 words
The combination according to claim 1, wherein said flanged collar at one end of said metal air-conveying member is at least partially molded inside said other end of said tubular shaped plastic body by means of an overlap deposited upon said flanged collar.
Claim 4
Dependent Claim
23 words
The combination according to claim 2, wherein the thickness of the walls of said plastic tubing is substantially one thirty-second of an inch.
Claim 5
Dependent Claim
82 words
The combination according to claim 1, wherein said other end of said plastic tubing is slidably engageable to an air-receiving member, said other end of said plastic tubing having an inside diameter which is smaller than the outside diameter of said air-receiving member when in its unstressed condition, and said other end of said tubing being deformed by said air-receiving member when secured thereto to provide the sole means of securement between said air-receiving member and said other end of said tubing.
Claim 6
Dependent Claim
23 words
The combination according to claim 3, wherein the walls of said metal air-conveying member have a thickness of about 0.008 of an inch.
