Abstract
Abstract A vacuum hose retainer apparatus for providing positive vacuum hose retention and improved assembly ease is disclosed. The vacuum hose retainer is comprised of an interiorly positioned deformable elastomeric material having a central bore extending therethrough. The central bore is sized on one end for an interference fit with a vacuum port and has an oversized section for receipt of the vacuum hose. The vacuum hose is preferably bonded to the interior of the elastomeric or insert member by suitable glues or solvents and is inserted therein in an interference fit condition. The vacuum hose retainer further includes a generally U-shaped metal housing body which is apertured on one end for passage of the vacuum port. This aperture is provided with inwardly directed gripping teeth and is adapted for passage of the vacuum hose through the opposite end.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
In combination with a hollow flexible hose for fluid tight communication with a rigid conduit, the improvement comprising: an insert member coupled to one end of the flexible hose and having an aperture for receipt of the rigid conduit, the aperture having a conical inner surface convergent toward, and coaxial with, the flexible hose; and a housing member having a first aperture aligned with said insert member conduit receiving aperture; said housing member having a pair of inwardly directed guidance ramp members extending generally toward each other and into the region defined by the conical inner surface of said insert member aperture; said guidance ramp members having V-shaped notches formed at their confronting ends to define said first aperture, the sides of said V-shaped notches being arranged for engagement with the rigid conduit; said housing member including arm means positioned on the side of said insert member opposite the rigid conduit aperture loosely surrounding and embracing the flexible hose.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein said arm means comprise means defining a second aperture and include upstanding flange portions for gripping, without puncturing, the flexible hose.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 wherein said guidance ramp members are positioned for loose contactive engagement with the conical surface of the insert member aperture.
Claim 5
Dependent Claim
30 words
The apparatus of claim 1 wherein said insert member extends along the flexible hose for a distance of the same order of magnitude as the length of the rigid conduit.
Claim 6
Dependent Claim
42 words
The apparatus of claim 1 wherein said guidance ramp members are flexible for permitting easy passage of the rigid conduit in a first insertion direction and, cooperative with the V-shaped notches, to inhibit passage of the rigid conduit in the opposite direction.
Claim 7
Dependent Claim
25 words
The apparatus of claim 5 wherein said insert material is selected to be resiliently at least as rigid as the material of the flexible hose.
