Abstract

A mobile hose reel assembly ( 100 ) includes a housing ( 110 ). The housing ( 110 ) includes a first wall ( 112 ), a second wall ( 114 ) coupled with and disposed opposite to the first wall ( 112 ) and a handle portion ( 116 ) coupled with the first wall ( 112 ) and the second wall ( 114 ). The housing ( 110 ) further includes a hose reel module ( 120 ) housed within the housing ( 110 ). The hose reel module ( 120 ) includes a hose reel ( 122 ), a drive motor ( 124 ) operatively coupled to the hose reel ( 122 ) and a transmission mechanism ( 126 ) adapted to transmit the motion of the drive motor ( 124 ) to the hose reel ( 122 ). The mobile hose reel assembly ( 100 ) is characterized in that the hose reel module ( 120 ) is adapted to exhibit a rocking motion relative to the housing ( 110 ). Further, the drive motor ( 124 ) is selectively activated and deactivated based on the rocking motion of the hose reel module ( 120 ) relative to the housing ( 110 ).

First claim

The invention claimed is:

1 . A mobile hose reel assembly comprising:
a housing, wherein the housing includes: a first wall; a second wall coupled with and disposed opposite to the first wall; and a handle portion coupled with the first wall and the second wall; a hose reel module housed within the housing, the hose reel module including: a hose reel; a drive motor operatively coupled to the hose reel; and a transmission mechanism adapted to transmit motion of the drive motor to the hose reel; wherein the hose reel module is adapted to exhibit a rocking motion relative to the housing; wherein the drive motor is selectively activated and deactivated by control electronics responsive to the rocking motion of the hose reel module relative to the housing being detected by the control electronics, wherein the first wall and the second wall each comprise at least one window defining an opening through the first wall and the second wall, wherein the hose reel module further comprises a pair of protrusions that extend into the at least one window at the first wall and the second wall, and wherein the at least one window defines an extent to which the pair of protrusions moves relative to the first wall and the second wall during the rocking motion which therefore defines the extent to which the hose reel module exhibits the rocking motion relative to the housing.

2 . The mobile hose reel assembly of claim 1 , wherein the drive motor is selectively activated and deactivated by a switch.

3 . The mobile hose reel assembly of claim 1 , wherein the transmission mechanism adapted to transmit the motion of the drive motor to the hose reel is a gear mechanism.

4 . The mobile hose reel assembly of claim 1 , wherein the transmission mechanism adapted to transmit the motion of the drive motor to the hose reel is a belt-drive mechanism.

5 . The mobile hose reel assembly of claim 1 , wherein a speed of the hose reel is adapted to be equivalent to walking speed of an operator when an amount of hose on the hose reel is changing during unwinding.

6 . The mobile hose reel assembly of claim 1 , wherein the mobile hose reel assembly includes a pair of guide rolls for guiding the hose during winding and unwinding operation of the hose.

7 . The mobile hose reel assembly of claim 1 , wherein the mobile hose reel assembly includes a slider adapted to regulate the speed of the hose reel.

8 . The mobile hose reel assembly of claim 6 , wherein at least one of the guide rolls from the pair of guide rolls is driven by the drive motor.

9 . The mobile hose reel assembly of claim 6 , wherein the pair of guide rolls and the hose reel are simultaneously driven during winding and unwinding by installing an equalizing or differential gear set between the pair of guide rolls and the hose reel.

10 . A mobile hose reel assembly comprising:
a housing, wherein the housing includes:
a first wall;
a second wall coupled with and disposed opposite to the first wall; and
a handle portion coupled with the first wall and the second wall;
a hose reel module housed within the housing, the hose reel module including:
a hose reel;
a drive motor operatively coupled to the hose reel; and
a transmission mechanism adapted to transmit motion of the drive motor to the hose reel;
wherein the hose reel module is adapted to exhibit a rocking motion relative to the housing,
wherein the drive motor is selectively activated and deactivated by control electronics responsive to the rocking motion of the hose reel module relative to the housing being detected by the control electronics, and
wherein the drive motor is selectively activated and deactivated by the control electronics responsive to the control electronics detecting an angle of a hose winded on the hose reel.

11 . The mobile hose reel assembly of claim 10 , wherein the drive motor is selectively activated and deactivated by a switch.

12 . The mobile hose reel assembly of claim 10 , wherein the transmission mechanism adapted to transmit the motion of the drive motor to the hose reel is a gear mechanism.

13 . The mobile hose reel assembly of claim 10 , wherein the transmission mechanism adapted to transmit the motion of the drive motor to the hose reel is a belt-drive mechanism.

14 . The mobile hose reel assembly of claim 10 , wherein a speed of the hose reel is adapted to be equivalent to walking speed of an operator when an amount of hose on the hose reel is changing during unwinding.

15 . The mobile hose reel assembly of claim 10 , wherein the mobile hose reel assembly includes a pair of guide rolls for guiding the hose during winding and unwinding operation of the hose.

16 . The mobile hose reel assembly of claim 10 , wherein the mobile hose reel assembly includes a slider adapted to regulate the speed of the hose reel.

17 . The mobile hose reel assembly of claim 15 , wherein at least one of the guide rolls from the pair of guide rolls is driven by the drive motor.

18 . The mobile hose reel assembly of claim 15 , wherein the pair of guide rolls and the hose reel are simultaneously driven during winding and unwinding by installing an equalizing or differential gear set between the pair of guide rolls and the hose reel.

19 . The mobile hose reel assembly of claim 10 , wherein the first wall and the second wall each comprise at least one window defining an opening through the first wall and the second wall,
wherein the hose reel module further comprises a pair of protrusions that extend into the at least one window at the first wall and the second wall, and wherein the at least one window defines an extent to which the pair of protrusions moves relative to the first wall and the second wall during the rocking motion which therefore defines the extent to which the hose reel module exhibits the rocking motion relative to the housing.
