Abstract

The battery-powered blower includes a housing assembly including a first housing portion having a first inner surface, a second housing portion having a second inner surface, and connected to the first housing portion, and a third housing portion connected to the second portion. The third housing portion has a side outer surface configured to receive a battery. The battery is mountable to the side outer surface of the third housing portion. The second housing portion in connection with to the first housing portion forms an inner chamber therebetween. A fan is provided in the inner chamber to facilitate airflow through the housing assembly and out an outlet, and a motor is provided intermediate to the second housing portion and the third housing portion. The center of gravity with respect to the overall blower is provided proximate to a handle portion.

First claim

What is claimed is:

1. A battery powered blower comprising:
a housing assembly defining an inner chamber for holding a fan, the housing assembly including a handle portion to be gripped by a user;
a motor mounted to a first side of the housing assembly;
the fan having an axis of rotation in a lateral direction of the housing assembly, and located on a second side of the housing assembly, opposite the first side of the housing assembly,
wherein the center-of-gravity of the blower is aligned with the handle portion so as to be substantially underneath the handle portion.

2. The battery powered blower of claim 1 , wherein the housing assembly includes a first, second and third housing portion, and wherein the inner chamber for the fan is formed by the first and second housing portion, and the battery is mounted to the third housing portion.

3. The battery powered blower of claim 1 , further including a battery mounted substantially on either the first or second side of the housing assembly.

4. The battery powered blower of claim 1 , further comprising a foot assembly removably secured to the bottom of the housing assembly so that only the foot assembly contacts a resting surface, the foot assembly having portions that are contoured to the shape of the battery to protect the battery against drops.

5. The battery powered blower of claim 1 , wherein the housing assembly includes a sleeve defining an air outlet for connecting to an outlet tube, the sleeve having a longitudinal axis, the handle having a longitudinal axis, and wherein the longitudinal axis of the sleeve lies in a different plane as the longitudinal axis of the handle.

6. A battery powered blower, comprising:
a housing assembly having a volute for holding a fan;
a handle portion attached to the housing assembly, the handle portion having a central longitudinal axis;
a motor disposed on one side of the handle portion;
a fan disposed on another side of the handle portion, and operatively connected to the motor; and
a battery attached to the housing assembly, wherein a majority of the battery lies within an outer perimeter defined by the volute.

7. The battery powered blower of claim 6 , further comprising a motor field case to enclose the motor.

8. The battery powered blower of claim 7 , further comprising a pulley system mounted to an exterior of the motor field case.

9. The battery powered blower of claim 8 , wherein the pulley system includes a generally circular, first gear and a generally circular second gear operatively connected, by a belt.

10. The battery powered blower of claim 6 , further comprising a pulley system to engage the motor and the fan.

11. The battery powered blower of claim 6 , wherein the battery is located to a side of the handle portion.

12. The battery powered blower of claim 6 , wherein the battery is positioned to the rear of the motor.

13. A battery powered blower, comprising:
a housing portion having a volute shaped interior surface and a sleeve defining an air outlet;
a tube having a proximal end, the proximal end received in the sleeve, the tube having a distal end, the distal end of the tube having a longitudinal axis that is laterally offset from the longitudinal axis of the sleeve;
a fan disposed on one side of the longitudinal axis of the sleeve to force air out of the tube; a motor and a battery disposed on a second side of the longitudinal axis of the sleeve; and
a handle portion provided at an upper portion of the housing portion, wherein the handle portion is provided in an offset position from a longitudinal axis of the sleeve.

14. The battery powered blower of claim 13 , further comprising a belt drive system and wherein the motor is operative connected to fan via the belt drive system.

15. The battery powered blower of claim 13 , further comprising a foot assembly to support the battery powered blower in a resting position wherein in the resting position the handle portion is in a top most position of the battery powered blower.

16. The battery powered blower of claim 13 , wherein the center of gravity of the battery powered blower lies laterally beneath the handle.

17. The battery powered blower of claim 13 , further comprising a foot member and a battery mount cooperatively forming a chamber to protect the battery if the battery powered blower is dropped.
