Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a portable air blower device for cleaning a rain gutter and other elevated surfaces and more particularly an air blower device when is attached to the upper end of a length adjustable extension pole. 
     2. Description of the Related Art 
     Many types of air blower devices and mechanical devices have been previously provided for cleaning leaves, twigs and other debris from rain gutters. For example, U.S. Pat. No. 4,402,106 discloses a hand-held air blower which has tubular extension members secured thereto. The major drawback of the device of U.S. Pat. No. 4,402,106 is the requirement that a plurality of extension tubes must be used with those tubes having no other useful purpose. The device of U.S. Pat. No. 4,402,106 also requires the use of an elbow at the upper end of the uppermost extension tube. 
     The device of Published Patent Application US 2004/0143931 requires the use of a straight extension and a gooseneck extension. There is also the possibility that the velocity of the air passing through the extensions of the three devices described above will be reduced since the air must be blown some distance from the air blower. 
     SUMMARY OF THE INVENTION 
     This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter. 
     A rain gutter cleaning apparatus is disclosed which includes an elongated extension pole having a lower handle and an upper end. An air blower is secured to the upper end of the pole. The air blower is powered by a battery directly affixed thereto so that all of the components of the air blower are positioned at the upper end of the extension pole. The air blower includes an air flow discharge tube whereby the air blower may be maneuvered by an operator grasping the handle of the extension pole so that the air flow from the air flow discharge tube may be directed into the rain gutter being cleaned to blow leaves, twigs and other debris from the rain gutter. 
     The apparatus of this invention may also be used to clean overhead or elevated structures. 
     In the preferred embodiment, the air blower is selectively removably secured to the upper end of the extension pole. 
     In the preferred embodiment, the upper end of the extension pole is threadably secured to the air blower. 
     It is therefore a principal object of the invention to provide an improved air blower device which may be used to clean twigs, leaves and other debris from a rain gutter or an overhead structure or elevated structure. 
     A further object of the invention is to provide a device of a type described wherein an air blower is secured to the upper end of an extension pole. 
     A further object of the invention is to provide a device of the type described which includes a self-contained and battery operated air blower mounted on the upper end of an extension pole for cleaning rain gutters and other elevated surfaces. 
     The further object of the invention is to provide a device of a type described which is easy to use and is safe to use. 
     These and other objects will be apparent to those skilled in the art.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims. 
     The air blower cleaning device of the invention is generally designated by the reference numeral  10  and may be used to clean leaves, twigs or other debris from a rain gutter  12  or an elevated surface or structure such as a roof, canopy, screen, etc. Device  10  is a battery operated air blower having a frame  14  with a handle  16  attached thereto. In some cases, the handle  16  may not be used but the handle  16  provides a means for carrying the device. Device  10  has an air discharge tube  18  extending therefrom. When the device  10  is activated, air is blown from the tube  18  in conventional fashion. 
     An internally threaded connector  20  is secured to the handle  16  or to the frame  14  of the device  10 . Connector  20  is adapted to threadably receive the externally threaded connector  22  of a length adjustable extension pole  24 . 
     In use, a charged battery  25  is affixed to the device  10  to power the same. The connector  22  of the extension pole  24  is threadably secured to connector  20 . The length of the extension pole  24  is then adjusted to the desired length. The device  10  is then activated. The operator then grasps the extension pole  24  and positions the device  10  relative to the rain gutter  12  so that the air being blown from the tube  18  will be directed into the rain gutter  12  to blow the twigs, leaves or other debris therefrom as seen in  FIGS. 1 and 4 . The device  10  is moved along the length of the rain gutter  12  so that the debris will be blown along the rain gutter and outwardly therefrom. 
     The device  10  is easily moved by the operator holding the extension pole  24  so that the discharged air is directed onto the debris to blow the debris from the rain gutter. As stated, the device  10  may be used to blow debris from other elevated surfaces or structures such as a roof, canopy, screen, etc. 
     It can therefore be seen that the invention accomplishes at least all of its stated objectives. 
     Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
