Abstract

An hose standoff comprises a sleeve molded onto a hose and a standoff flange extending circumferentially from the sleeve. The flange contacts a surface to which the hose is adjacent, spacing the hose away from the surface and any proximate edges. The sleeve may extend from the flange, along the hose, in at least one direction to protect the hose from abrasion or cutting by an edge extending perpendicular from the surface toward the hose. A metal collar may be crimped onto the hose with the sleeve overmolding the collar. Also, a fabric covering may be disposed over the hose with the collar crimped over the fabric covering and the sleeve overmolding the collar and at least a portion of the fabric covering. Preferably the sleeve overmold contacts and bonds or otherwise mechanically locks with the fabric covering and/or the underlying hose.

First claim

What is claimed is:

1. A hose assembly comprising a hose with an integral hose standoff comprising:
a sleeve portion molded onto the hose at a distance from the ends of the hose and from any end fitting present on the hose;
a collar disposed about said hose, said sleeve portion overmolds said collar and extends beyond at least one end of said collar, contacting said hose;
a standoff flange portion extending circumferentially from said sleeve portion, said flange portion adapted to contact a surface to which said hose is disposed adjacent, spacing said hose away from the surface and edges proximate said surface,
whereby said sleeve portion protects said hose from abrasion or cutting by the surface or the edge.

2. The hose assembly of claim 1 , wherein said sleeve portion extends from said flange portion, along said hose, in both directions.

3. The hose assembly of claim 2 wherein said sleeve portion extends from said flange farther along said hose in one direction than the other.

4. The hose assembly of claim 1 , wherein said sleeve portion extends from said flange portion, along said hose, in at least one direction.

5. The hose assembly of claim 1 , wherein said sleeve portion extends beyond both ends of said collar, contacting said hose.

6. The hose assembly of claim 5 , wherein said portion of said sleeve portion that contacts said hose at least partially bonds with an exterior of said hose.

7. The hose assembly of claim 5 , wherein said collar prevents collapse of said hose when said sleeve portion and flange portion are molded onto said hose.

8. The hose assembly of claim 1 , wherein said collar is made of metal.

9. The hose assembly of claim 8 wherein said collar is crimped onto said hose.

10. The hose assembly of claim 9 , further comprising a fabric covering disposed over said hose, said collar crimped over said fabric covering and said sleeve portion overmolding said collar and at least a portion of said fabric covering.

11. The hose assembly of claim 10 , wherein said sleeve portion extends beyond at least one end of said collar to contact said fabric covering.

12. The hose assembly of claim 11 , wherein said portion of said sleeve portion that extends to said covering at least partially bonds with said covering.

13. The hose assembly of claim 1 wherein said flange is a circular flange of greater diameter than said sleeve.

14. A method comprising:
crimping a collar onto a hose at a distance from the ends of the hose and from any end fitting present on the hose;
overmolding a sleeve onto said hose at a distance from the ends of the hose and from any end fitting present on the hose, said sleeve defining a standoff flange extending circumferentially from said sleeve, wherein said overmolding comprises overmolding said collar and extending said sleeve beyond at least one end of said collar to contact said hose;
said standoff flange adapted to contact a surface, spacing said hose from said surface and edges proximate to said surface thereby protecting said hose from abrasion or cutting by said edges or said surface.

15. The method of claim 14 , wherein said sleeve portion extends from said flange along the hose in both directions, and farther along said hose in one direction than the other.

16. The method of claim 14 , further comprising:
extending said sleeve from said flange, along said hose, in at least one direction.

17. The method of claim 14 , further comprising:
extending said sleeve from said flange, along said hose, in both directions.

18. The method of claim 17 , further comprising extending said sleeve beyond both ends of said collar to contact said hose.

19. The method of claim 14 , further comprising:
extending said sleeve beyond at least one end of said collar to a cover of said hose; and
at least partially bonding said sleeve with said cover.

20. The method of claim 19 wherein said cover is fabric.

21. The method of claim 14 , further comprising:
preventing collapse of said hose with said collar when said sleeve and flange are overmolded onto said hose.

22. The method of claim 14 further comprising:
locating said hose in an injection mold using said collar.
