CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 61/528,395 entitled “Handheld Battery Operated Blower” filed Aug. 29, 2011, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, in general, to blowers and, more particularly, to blowers that are portable, handheld, and battery operated and configured for use to quickly and safely kindle or maintain a fire.

2. Description of Related Art

Traditional squeeze type bellows have existed for centuries and are known prior art. Historically, traditional bellows were necessary for kindling and maintaining wood, coal, or charcoal burning fires, but are today pieces of decorative art rather than efficient tools. Traditional bellows are manually operated and provide an intermittent, rather than continuous flow of air which is more efficient in kindling and maintaining a fire. Traditional bellows typically lack portability.

There have also been a number of attempts to create a blower to run on electricity or batteries. For instance, U.S. Pat. No. 6,571,788 to Goldstein discloses an electric bellows system for stimulating and igniting a fire in a safe and efficient manner. In addition, U.S. Pat. No. 4,190,034 to Wonisch discloses an apparatus for starting and fanning a fire and U.S. Pat. No. 4,810,173 to Thomson et al. discloses a fire booster to aid in building a fire in fireplaces, wood burning stoves, campfires, and charcoal grills. However, while each of these devices may work as intended and fulfill their respective objectives, each device suffers from various deficiencies.

Accordingly, a need exists for a blowing device that is small enough to be portable and fit comfortably in the hand. A further need exists for a blowing device that provides an efficient flow of air through the device. An additional need exists for a blowing device that is powerful enough to make a significantly noticeable increase in the activity and temperature of a fire when applied. Finally, a need exists for an economical blowing device that is easy to operate.

SUMMARY OF THE INVENTION

Accordingly, it is an objective of the present invention to provide a portable, handheld, and battery powered blower that is easy to operate yet powerful enough to make a significantly noticeable increase in the activity and temperature of a fire when applied. In addition, it is an objective of the present invention to provide a blower that can also be used to: blow ashes back into a fireplace; blow crumbs from a picnic table; and be used as a personal cooling device or any other use a person might find for a simple, portable blower.

For purposes of the description hereinafter, the terms “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, “lateral”, “longitudinal”, and derivatives thereof shall relate to the invention as it is oriented in the drawing figures. However, it is to be understood that the invention may assume alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the invention. Hence, specific dimensions and other physical characteristics related to the embodiments disclosed herein are not to be considered as limiting.

With reference to FIGS. 1-6, a blower 10 includes a hollow, generally cylindrical shaped body that houses an electric motor 26 and a turbine blade 30 for drawing air from an open rear end of the body to a front tip 2 of the body. The blower 10 includes a baffle control 4, a power button 6, a hinge 8, and battery compartment cover 12 on the top surface and a retainer ring 14 at the rear of the unit. The retainer ring 14 includes retainer ring locking slots 38 (see FIG. 6). Also shown is the front tip 2 of the blower 10. Visible on the bottom surface is a footer 16, grip left side 18, and strap ring 20. The blower also includes a grip right side 52.

With specific reference to FIG. 5, positioned within the inside of the blower 10 is a baffle 22, front screw boss 24, blade cowling 40, electric motor 26, power button contact 28, turbine blade 30, battery compartment 32, batteries 34, front screw boss 24, and rear screw boss 36.

With continued reference to FIGS. 1-6, the blower 10 having a baffle control 4, power button 6, hinge 8, and battery compartment cover 12 on the top surface and a retainer ring 14 at a rear portion thereof, also includes the front tip 2 that directs the flow of air and contains the footer 16, a hole to contain the baffle control 4, and markings to show the direction to turn the control to open or close the baffle 22. The size and shape of the front tip 2 is designed to maximize the flow of air through the device and contains an opening at the tip.

The grip right side 52 and grip left side 18 are joined together with screws that go through the holes in the grip left side 18 and are secured into the front screw boss 24 and rear screw boss 36. The grip right side 52 and grip left side 18 join together to create a hole at the top to contain the power button 6 and receptacles for the hinge 8, the two sides of which are at the front of the battery compartment cover 12.

The retainer ring 14 at the rear of the blower 10 serves as the air intake and contains locking slots 38 that secure the battery compartment door. The retainer ring 14 also contains a strap ring 20 to accept a small leather strap or other device for hanging the blower 10. The strap ring 20 also serves as a balancing point to keep the blower 10 in proper orientation when set down. The back of the retainer ring 14 is flat so it can stand upright if set down on the rear end.

Turning now to the inner workings of the device, FIGS. 5 and 6 illustrate the baffle 22 and baffle control 4 provided to regulate the flow of air through the blower 10. The baffle control 4 can be turned left or right by twisting the baffle 22 to present a greater or lesser surface to decrease or increase the flow of air through the body of the blower 10.

The shape of the blower 10, as illustrated in FIGS. 1-6, has been carefully designed to accomplish multiple goals. First, the shape of the blower 10 promotes the greatest flow of air so the blower 10 can be held at a safe distance and still create a noticeable increase in the activity and temperature when applied. In addition, the shape of the blower is of a size that fits comfortably in an adult hand.

A further aspect of the blower 10 of the present invention is that it utilizes a turbine blade 30 rather than a conventional fan blade. The turbine blade 30 has more aggressive blade angles and more blades with closer distances than a traditional fan blade. For instance, turbine blade 30 includes eight blades extending from a hub. Each of the eight blades extend from the hub at an angle of about 28 degrees and then twists at an angle of about 52 degrees. The outside diameter of the turbine blade 30 is approximately 1.575 inches and the outside diameter of the hub is about 0.575 inches. The use of the turbine blade 30 in conjunction with the shape of the device allows the blower 10 to create a significantly noticeable increase in the activity and temperature of the fire when applied.

The power button 6 interacts with the power button contact 28 to power the electric motor 26 only when the button is depressed. The electric motor 26, when powered, causes the turbine blade 30 to rotate, thereby drawing air into the blower 10 through the retainer ring 14 and directing the air out of the tip 2.

Each component of the blower 10, with the exception of the electric motor 26, batteries 34, and power button contact 28, are made from AFS plastic in a variety of colors and finishes. The power button 6 and baffle control 4 are made from AFS plastic in a variety of colors and finishes with fluorescence added. Alternatively, each component of the blower 10, with the exception of the electric motor 26, batteries 34, and power button contact 28, may also be made from high strength, heat resistant plastic in a variety of colors and finishes. The power button 6 and baffle control 4 are made from high strength, heat resistant plastic in a variety of colors and finishes with or without fluorescence added. Please note that this is not to be construed as limiting the present invention as the components of the blower may be made of any other suitable material. The power button 6 and power button contact 28 can be designed with a locking mechanism, if desired.

The blower 10 can use a different number or size of batteries than illustrated in FIG. 6, assuming they fit within a similar shape and are not allowed to protrude further into the interior space thereby limiting the flow of air. The blower 10 can also be powered by a combination of rechargeable batteries and a charging unit or through an AC adapter.

With reference to FIG. 7, an alternative embodiment of the blower, designated generally as reference numeral 50, is illustrated. The blower 50 is identical to blower 10 except that it is manufactured without the baffle 22 and baffle control 4. Blower 50, even without baffle 22 and baffle control 4, still functions to create a significantly noticeable increase in the activity and temperature of the fire.

The blower 10, 50 of the present invention provides several advantages and features when compared with conventional blowers. First, the power button 6 and baffle control 4 are made from AFS plastic in a variety of colors and finishes with fluorescence to make the blower 10, 50 easy to find and use in dark situations. In addition, the power button 6 interacts with the power button contact 28 to power the motor only when the power button 6 is depressed. If the blower 10, 50 is dropped, it ceases blowing immediately, eliminating the risk of continuing to accidentally blow air into the fire possibly causing an unsafe situation.

The footer 16 functions as a wide, primary balancing point and the strap ring 20 as a secondary balancing point so the blower 10, 50 sits in the proper orientation when set down making it more attractive when not in use and easier to pick up in the proper orientation for immediate action when put back into use.

Furthermore, the blower 10 uses a turbine blade 30, with more aggressive blade angles and more blades with closer distances than a traditional fan blade. It is the use of the turbine blade 30 in conjunction with the shape of the blower 10, 50 that allows it to create a significantly noticeable increase in the activity and temperature of the fire when applied. Tests with traditional fan blades simply fail to create the necessary flow of air to effectively raise the temperature and spread the fire.

While specific embodiments of the device of the present disclosure have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the device of the present disclosure which is to be given the full breadth of the claims appended and any and all equivalents thereof.
