Direct drive hose reel assembly

Abstract

A hose reel assembly includes a spool having an inner spool core defining an inner core cavity on a support side of the hose reel assembly, an outer core defining an outer core cavity on a fluid path side of the hose reel assembly and a pair of opposed outer disc walls with a single assembly including a support frame having a support member. A hub assembly is included having a hub shaft located within the inner core cavity and the outer core cavity, and fluid path components, in which the support member supports the static load of the spool from the support side only and remote from the fluid path side and with the fluid path components mounted on the fluid supply side only and with a fluid path not extending into, or through, the hub assembly.

What is claimed is: 
     
         1 . A hose reel assembly, comprising:
 a spool comprising an inner spool core defining an inner core cavity on a support side of said hose reel assembly, an outer core defining an outer core cavity on a fluid path side of said hose reel assembly and a pair of opposed outer disc walls;   a single assembly comprising a support frame having a support member; and,   a hub assembly comprising a hub shaft located within the inner core cavity and the outer core cavity, and fluid path components, wherein the support member supports the static load of the spool from said support side only and remote from said fluid path side and with said fluid path components being mounted on said fluid supply side only and with a fluid path not extending into, or through, said hub assembly.   
     
     
         2 . The hose reel assembly of  claim 1 , further comprising a gear assembly that comprises one or more ring gears surrounding a hub shaft that is contiguous with a hub and cooperates with a drive unit to multiply torque from the drive unit to the hub. 
     
     
         3 . The hose reel assembly of  claim 1 , further comprising a drum-shaped gearbox within the inner core cavity defined by the inner spool core surrounding said hub shaft that is contiguous with a hub and cooperates with a drive unit to multiply torque from the drive unit to the hub. 
     
     
         4 . The hose reel assembly of  claim 2 , wherein the drive unit is a manual crank rotatably mounted to a static upper part of the support member. 
     
     
         5 . The hose reel assembly of  claim 2 , wherein the drive unit is a sprung or motorised unit. 
     
     
         6 . The hose reel assembly of  claim 5 , wherein the drive unit directly drives the gear assembly and is partially housed in the inner spool core. 
     
     
         7 . The hose reel assembly of  claim 2 , wherein the support frame comprises a base extending underneath the spool for mounting the support member to a sub-structure and the support member comprises a lower upright section, an intermediate section angled towards the spool and an upper static section to which is mounted the drive unit. 
     
     
         8 . The hose reel assembly of  claim 2 , wherein the hub assembly comprises the hub and forms a part of the gearbox assembly. 
     
     
         9 . The hose reel assembly of  claim 8 , wherein the hub bears said one or more ring gears for engaging with other gears in a drive train operatively connected to the drive unit. 
     
     
         10 . The hose reel assembly of  claim 12 , wherein the hub assembly further comprises a hub and spigot bolts extending from the hub for cooperating with corresponding apertures in the spool core inner faces of the inner and outer cores at the inner walls to mount to hub stub axle. 
     
     
         11 . The hose reel assembly of  claim 3 , wherein the drum-shaped gearbox houses a gear reduction set which is located within the inner spool core. 
     
     
         12 . The hose reel assembly of  claim 1 , wherein the spool is formed from two opposing inner and outer spool disc components which abut one and other face to face at inner walls substantially lying in a plane transverse to the axis of the inner and outer spool disc components. 
     
     
         13 . The hose reel assembly of  claim 12 , wherein the spool core comprising the inner spool core and the outer core has an exterior surface concentric with the axis of the inner core and the outer core about which a hose can be wound, the exterior surface tapering concentrically towards the inner walls, and with a riser extending through the exterior surface of the outer spool core. 
     
     
         14 . The hose reel assembly of  claim 1 , wherein the fluid path components are attachable and detachable from the spool via access from the fluid supply side without first removing the spool from the hub.
