Abstract

A hose reel spool has an annular ring defining an axial hub, and two concave side walls. The side walls extend radially outward from the ends of the annular ring, and slant axially inward to converge towards each other as they extent radially outward.

Claims

1. A hose reel comprising:

a hose reel frame; and

a hose reel spool rotatably mounted on the house reel frame, the hose reel spool comprising;

a cylindrical wall defining an axis, the cylindrical wall having first and second axial ends;

a first concave side wall located at the first axial end of the annular ring, and extending radially outward from the cylindrical wall; and

a second concave side wall located at the second axial end of the annular ring, and extending radially outward from the cylindrical wall;

wherein the first and second dished side walls slant axially inward to converge towards one another.

2. The hose reel of claim 1, wherein the radially outermost edges of the first and second side walls turns axially outward in lips.

3. The hose reel of claim 2, wherein neither lip is the axially outermost extent of the hose reel spool.

4. The hose reel of claim 1, wherein the hose reel frame comprises:

a frame side to support the hose reel spool;

a mount in the frame side for rotatably attaching the annular ring; and

a flange extending axially inward toward the spool from the mount toward the annular ring for strengthening the hose reel frame;

wherein the axially inward slants of the first and second side walls prevent the hose reel spool from contacting the flange.

5. The hose reel of claim 4, further comprising a guide arm with a section radially outward of the first and second side walls to guide hose into the hose reel spool, the hose reel frame extending no wider axially than the guide arm.

6. The hose reel of claim 1, wherein the first side wall extends directly radially outward to form a flat attachment surface before slanting axially inward toward the second side wall.

7. The hose reel of claim 1, further comprising a ratchet element affixed to an outer surface of one of the side walls.

8. The hose reel of claim 4, further comprising

a ratchet element affixed to an outer surface of one of the side walls;

and

a hose mount for mounting the hose on the cylindrical wall, the hose mount located on a portion of the cylindrical wall radially opposite from the ratchet element.

9. The hose reel of claim 8, wherein the ratchet element is a circular arc, toothed to catch a pawl.

10. A hose reel spool providing a hose retaining area for coiling a hose, the hose retaining area defined:

at an inner radial extent by a cylindrical wall;

at a front axial extent by a dished, axially backward-slanting first side wall extending radially outward from the cylindrical wall; and

at a back axial extent opposite the front axial extent, by a dished, axially forward-slanting second side wall extending radially outward from the cylindrical wall.

11. The hose reel spool of claim 10, further comprising a hose mount for mounting hose of a particular hose width on the cylindrical wall, wherein the axial width of the hose retaining area at its inner radial extent is slightly greater than four times the particular hose width.

12. The hose reel spool of claim 10, wherein the radially outermost edges of the first and second side walls end in axially outward-turning lips.

13. The hose reel spool of claim 10, wherein the hose reel spool comprises:

a first half making up the first side wall and a part of the cylindrical wall; and

a second half making up the second side wall and the remainder of the cylindrical wall.

14. The hose reel spool of claim 10, further comprising a ratchet element affixed to an outer surface of the first side wall.

15. The hose reel spool of claim 14, further comprising a hose attachment point on the cylindrical wall for attaching the hose to the hose reel spool, the attachment point located radially opposite the ratchet element.

16. A hose reel spool for holding a hose, the hose reel spool comprising:

a first piece having a first cylindrical portion and a first side wall extending radially outward from an end of the cylindrical portion; and

a second piece having a second cylindrical portion and a second side wall extending radially outward from an end of the cylindrical portion;

wherein the first and second pieces are connected so that the first and second cylindrical portions meet to form a single cylindrical wall, and the first and second side walls converge towards each other.

17. The hose reel spool of claim 16, wherein the first side wall includes a ratchet element capable of catching on a nearby pawl.

18. The hose reel spool of claim 16, wherein

the radially outermost edge of the first side wall turns axially outward, away from the second side wall, in a first strengthening lip;

and

the radially outermost edge of the second side wall turns axially outward, away from the first side wall in a second strengthening lip.

19. The hose reel spool of claim 16, wherein the second side wall includes an annular ridge which protrudes axially away from the first side wall.

20. The hose reel spool of claim 16, wherein the single annular wall has a width slightly greater than four times the width of the hose.
