Abstract

An articulated pole for use as an extension in fluid spraying devices. The pole includes a flexible high pressure fluid hose that passes through a hinge which is part of a tubular outer housing. The fluid hose transports the fluid under pressure from a fluid source, connected on one end of the pole, to a spray tip nozzle, located on the other end of the pole. The hinge can be locked at any angle through its full range of pivotal movement or can be adjusted to customize the level of friction required for continuous pivot movement. Multiple hinges can be placed along the pole to allow for compound bending moments and to allow greater maneuverability for the person operating the fluid spraying device.

Claims

1. An articulated pole for spraying of fluids comprising:

an inlet attachment for attaching the pole to a fluid source;

a nozzle, in fluid communication with the inlet attachment, defining a flow path over which a fluid travels;

a flexible fluid hose extending between the nozzle and the inlet attachment, the fluid hose serving to transport fluid from the inlet attachment to the nozzle;

an elongated tubular housing, segmented into a plurality of pieces, connected on one end to the nozzle and connected on a second end to the inlet attachment, the housing surrounding the fluid hose, the pieces joined by hinges.

2. An articulated pole for fluid spraying, as in claim 1, wherein the housing is segmented into a first piece and a second piece, with a hinge connected therebetween allowing the first piece of housing to pivot relative to the second piece of housing.

3. An articulated pole for fluid spraying, as in claim 1, wherein the housing is segmented into a first piece, a second piece and a third piece, a first hinge being connected between the first piece and the second piece to allow the first piece to pivot relative to the second piece, and a second hinge being connected between the second piece and the third piece to allow the second piece to pivot relative to the third piece.

4. An articulated pole for fluid spraying, as in claim 1, wherein each hinge includes a pair of brackets, each bracket being secured to one of the pieces of housing and having an end secured to the end of the other bracket such that the hinge pivots at a point where the ends of the brackets are joined.

5. An articulated pole for fluid spraying, as in claim 1, wherein each hinge is locked at a desired angle so as to affix the pieces of housing in a stationary position.

6. An articulated pole for fluid spraying, as in claim 1, wherein the hinge has a pivoting limit, the pivoting limit being adjustable.

7. An articulated pole for fluid spraying, as in claim 1, wherein the flexible fluid hose is of a high pressure type, the hose being rated to withstand a pressure greater than 2000 psi.

8. An articulated pole for fluid spraying comprising:

an inlet attachment for attaching the pole to a fluid source;

a nozzle, in fluid communication with the inlet attachment, defining a flow path over which a fluid travels;

a flexible fluid hose extending between the nozzle and the inlet attachment, the fluid hose serving to transport the fluid under pressure from the inlet attachment to the nozzle;

an elongated tubular housing, segmented into a first piece of housing and a second piece of housing, each piece of housing having a first end and a second end, the first end of the first piece of housing being connected to the inlet attachment, the first end of the second piece of housing being connected to the nozzle, the tubular housing surrounding the flexible fluid hose; and

a hinge having jointed U-shaped members disposed between the second end of the first piece of housing and the second end of the second piece of housing, each member being secured to one of the pieces of housing and having an end secured to the end of the other member such that the hinge pivots at a point where the ends of the members are joined allowing the second piece of housing to pivot relative to the first piece of housing.

9. An articulated pole for fluid spraying, as in claim 8, wherein the hinge is locked at a desired angle such that the second piece of housing remains stationary relative to the first piece of housing.

10. An articulated pole for fluid spraying, as in claim 8, wherein the hinge has a pivoting limit, the pivoting limit being adjustable.

11. An articulated pole for fluid spraying, as in claim 8, wherein the flexible fluid hose is of a high pressure type, the hose being rated to withstand a pressure greater than 2000 psi.

12. An articulated pole for fluid spraying, as in claim 8, further comprising:

a third piece of housing and a second hinge;

the third piece of housing being disposed between the hinge and the second hinge, the second hinge being disposed between the third piece of housing and the second end of the second piece of housing, the hinge allowing the first piece of housing to pivot relative to the third piece of housing and the second hinge allowing the second piece of housing to pivot relative to the third piece of housing.

13. An articulated pole for fluid spraying comprising:

an inlet attachment for attaching the pole to a paint source;

a nozzle, in fluid communication with the inlet attachment, defining a flow path over which a paint travels;

a flexible fluid hose extending between the nozzle and the inlet attachment, the fluid hose serving to transport the paint under pressure from the inlet attachment to the nozzle;

an elongated tubular housing wherein the housing is segmented into a first piece, a second piece, and a third piece, a first end of the first piece of housing being connected to the inlet attachment, a first end of the third piece of housing being connected to the nozzle, the housing surrounding the flexible fluid hose; and

first and second hinges having jointed U-shaped members, the first hinge being disposed between the second end of the first piece of housing and the first end of the second piece of housing, the first hinge allowing the second piece of housing to pivot relative to the first piece of housing, the second hinge being disposed between the second end of the second piece of housing and the second end of the third piece of housing, the second hinge allowing the third piece of housing to pivot relative to the second piece of housing.

14. An articulated pole for fluid spraying, as in claim 13, wherein each member is secured to one of the pieces of housing and has an end secured to the end of the other member such that the hinge pivots at a point where the ends of the members are joined.

15. An articulated pole for fluid spraying, as in claim 13, wherein the hinges can be locked at a desired angle so as to affix the pieces of housing in a stationary position.

16. An articulated pole for fluid spraying, as in claim 13, wherein the hinges have a pivoting limit, the pivoting limit being adjustable.

17. An articulated pole for fluid spraying, as in claim 13, wherein the flexible fluid hose is of a high pressure type, the hose being rated to withstand a pressure greater than 2000 psi.

18. An articulated pole for fluid spraying comprising:

an inlet attachment for attaching the pole to a paint source;

a nozzle, in fluid communication with the inlet attachment defining a flow path over which a paint travels;

a flexible fluid hose extending between the nozzle and the inlet attachment, the fluid hose serving to transport the paint from the inlet attachment to the nozzle at a high pressure;

an elongated tubular housing, segmented into a number of pieces, the tubular housing being connected on one end to the nozzle and being connected on a second end to the inlet attachment, the housing encasing the fluid hose; and

a number of hinges connected between the pieces of housing, each hinge including a pair of jointed, U-shaped members each member being secured to one of the pieces of housing and having an end secured to the end of the other member such that the hinge pivots at a point where the ends of the brackets are joined, each hinge having an adjustable pivoting limit.
