Abstract

A pivoting blow-gun with a pivoting barrel having sufficient strength to receive pressurized air while at the same time dimensioned to allow the manipulation of the pivoting barrel into non-linear configurations which non-linear configurations are maintainable during use of the blow-gun in order to use the pivoting blow-gun to reach areas which would otherwise be hard to reach. A quick-connect attachment device can be used to permit relatively fast and easy changing of barrels.

Claims

1. A pivoting blow-gun, comprising, in combination:

a handle having an intake end and an outtake end and a trigger disposed therebetween, said handle is dimensioned to receive pressurized air through said intake end and deliver said pressurized air through said outtake end, said trigger is dimensioned to regulate the flow of said pressurized air; and

a pivoting barrel coupled to said outtake end of said handle, said pivoting barrel having sufficient strength to receive pressurized air from said outtake end of said handle while at the same time said pivoting barrel is dimensioned to allow the manipulation of said pivoting barrel into non-linear configurations, said non-linear configurations are maintainable during passage of air through said pivoting barrel.

2. The pivoting blow-gun of claim 1 further comprising a tip having an intake end and an outtake end, said intake end of said tip is coupled to an end of said pivoting barrel opposite said handle and said outtake end of said tip is narrower than said intake end of said tip resulting in a more pressurized air flow exiting said outtake end of said tip.

3. The pivoting blow-gun of claim 2 wherein said tip defines a safety by-pass opening dimensioned to allow pressurized air to exit said opening when said outtake end of said tip becomes obstructed.

4. The pivoting blow-gun of claim 1 wherein said pivoting barrel comprises a plurality of interlocking members.

5. The pivoting blow-gun of claim 4 wherein each said plurality of interlocking members comprises:

a substantially spherical projection;

a substantially triangular base; and

a sleeve joining said spherical projection to said triangular base.

6. The pivoting blow-gun of claim 5 wherein said plurality of interlocking members are made of hard-plastic and injection-molded.

7. The pivoting blow-gun of claim 5 wherein said pivoting barrel defines a channel extending through an interior portion of said substantially spherical projection and through an interior portion of said substantially triangular base and through an interior portion of said sleeve.

8. The pivoting barrel of claim 7 wherein said channel broadens between a base of said spherical projection and a top of said triangular base in order to remain open during pivoting of said interlocking members relative to each other.

9. The pivoting blow-gun of claim 8 wherein said substantially spherical projection and said substantially triangular base are coupled sufficiently loose to permit said interlocking members to be pivoted relative to each other in a horizontal or vertical plane while maintaining said channel in an open position and at the same time said substantially spherical projection and said substantially triangular base are coupled sufficiently tight to permit said interlocking members to retain a post-pivoted position during use of said pivoting blow-gun.

10. A blow-gun, comprising, in combination:

a handle having an intake end and an outtake end and a trigger disposed therebetween, said handle is dimensioned to receive pressurized air through said intake end and deliver said pressurized air through said outtake end, said trigger is dimensioned to regulate the flow of said pressurized air;

a barrel having an intake end and an outtake end; and

a quick-connect attachment device comprising two mating members, one of said mating members being located on said outtake end of said handle and a corresponding other of said two mating members being located on said intake end of said barrel.

11. The blow-gun of claim 10 wherein said barrel is a pivoting barrel having sufficient strength to receive pressurized air from said outtake end of said handle while at the same time said pivoting barrel is dimensioned to allow the manipulation of said pivoting barrel into non-linear configurations, said non-linear configurations are maintainable during passage of air through said pivoting barrel.

12. The blow-gun of claim 11 further comprising a tip having an intake end and an outtake end, said intake end of said tip is coupled to an end of said pivoting barrel opposite said handle and said outtake end of said tip is narrower than said intake end of said tip resulting in a more pressurized air flow exiting said outtake end of said tip.

13. The blow-gun of claim 12 wherein said tip defines a safety by-pass opening dimensioned to allow pressurized air to exit said opening when said outtake end of said tip becomes obstructed.

14. The blow-gun of claim 11 wherein said pivoting barrel comprises a plurality of interlocking members.

15. The blow-gun of claim 14 wherein each said plurality of interlocking members comprises:

a substantially spherical projection;

a substantially triangular base; and

a sleeve joining said spherical projection to said triangular base.

16. The blow-gun of claim 15 wherein said plurality of interlocking members are made of hard-plastic and injection-molded.

17. The blow-gun of claim 15 wherein said pivoting barrel defines a channel extending through an interior portion of said substantially spherical projection and through an interior portion of said substantially triangular base and through an interior portion of said sleeve.

18. The pivoting barrel of claim 17 wherein said channel broadens between a base of said spherical projection and a top of said triangular base in order to remain open during pivoting of said interlocking members relative to each other.

19. The blow-gun of claim 18 wherein said substantially spherical projection and said substantially triangular base are coupled sufficiently loose to permit said interlocking members to be pivoted relative to each other in a horizontal or vertical plane while maintaining said channel in an open position and at the same time said substantially spherical projection and said substantially triangular base are coupled sufficiently tight to permit said interlocking members to retain a post-pivoted position during use of said pivoting blow-gun.

20. A blow-gun useful in cleaning operations comprising, in combination:

a handle having an intake end and an outtake end and a trigger disposed therebetween, said handle is dimensioned to receive water through said intake end and deliver said water through said outtake end, said trigger is dimensioned to regulate the flow of said water;

a pivoting barrel coupled to said outtake end of said handle, said pivoting barrel having sufficient strength to receive water from said outtake end of said handle while at the same time said pivoting barrel is dimensioned to allow the manipulation of said pivoting barrel into non-linear configurations, said non-linear configurations are maintainable during passage of water through said pivoting barrel; and

a cleaning solution hose coupled proximate said outtake end of said handle so as to permit mixing of cleaning solution passing therethrough with said water and discharge of said cleaning solution and said water through said barrel.
