Abstract

A portable air blower is provided for use around the home for purposes of drying a freshly washed vehicle or the like. The blower is supported on top of the arm of the user and proximate the user'"'"'s shoulder as the user'"'"'s arm passes through a rigid loop support which stabilizes the blower on the user'"'"'s arm. The blower can be so operated for extended periods without the user becoming exhausted. An electric motor powers a fan and electrical resistance coils heat the air which passes therethrough.

Claims

1. In a portable blower of the type having means for driving a fan in a housing for forcing air through an elongated conduit joined to the housing, the improvement comprising:

means to stabilize the blower on top of the arm of the user proximate the user'"'"'s shoulder, said stabilizing means comprising a rigid loop-like support, said support laterally affixed to said housing to allow the arm of the user to pass therethrough.

2. The portable blower of claim 1 and including means for the user to grip the blower, said gripping means affixed to said elongated conduit forward of said housing.

3. The portable blower of claim 2 and including a trigger switch, said trigger switch proximate said gripping means.

4. The portable blower of claim 3 wherein said trigger switch is connected to said motor.

5. The portable blower of claim 1 and including a means to heat said forced air, said heating means positioned within said housing.

6. The portable blower of claim 1 and included an arcuate nozzle, said nozzle joined to said elongated conduit.

7. The portable blower of claim 6 wherein said nozzle is curved in a direction lateral to the direction of the air flow through said elongated conduit.

8. The portable blower of claim 6 wherein said nozzle includes a rim, said rim formed from a resilient material.

9. The portable blower of claim 8 wherein said nozzle rim is formed from a deformable synthetic polymer.

10. The portable blower of claim 9 wherein said nozzle rim is formed from a polyvinyl chloride composition.

11. In a portable blower having means for driving a fan, a heater, said drive means, heater and fan contained within a housing, said housing joined to a conduit for directing air from the fan therethrough, the improvement comprising:

means to stabilize said blower on top of the arm of the user proximate the user'"'"'s shoulder, said stabilizing means comprising a loop-like support, said support integrally formed with said housing, said support for receiving the arm of the user, said stabilizing means positioned laterally across the underside of said housing.

12. The blower of claim 11 and including means to grip the housing, said gripping means positioned on said conduit forward of said housing in alignment with said stabilizing means.

13. The blower of claim 12 and including a trigger switch, said trigger switch pivotally affixed proximate said gripping means.

14. The blower of claim 12 and including a deformable nozzle rim, said nozzle rim affixed to said conduit.

15. The blower of claim 14 wherein said nozzle is arcuately shaped.

16. The blower of claim 15 and including a resilient nozzle rim.

17. In a portable electric blower having an electric motor and heater, said motor for driving a fan, said motor, heater and fan contained within a housing, said housing joined to a conduit for directing air from the fan therethrough, the improvement comprising:

means to stabilize said blower, said stabilizing mean comprising a rigid loop support, said support positioned laterally on said conduit for receiving the arm of the user to maintain the blower on top of the user'"'"'s arm proximate the user'"'"'s shoulder, said stabilizing means positioned on the underside of said conduit, a means by which to grip the blower, said gripping means positioned on said conduit forward of said stabilizing means, a switch, said switch proximate said gripping means for controlling said motor.

18. The blower of claim 17 and including an arcuate nozzle.
