## Background
FIELD OF THE INVENTION
The present invention relates to a golf course cleaning device designed to remove debris from an area on a golf course, more specifically but not by way of limitation, the golf course green cleaning device is configured to substantially remove the debris present within the predicted putting path of a golf ball.
BACKGROUND
Millions of individuals engage in the game of golf either as a recreational sport or at a competitive level. Many of those that play the game of golf regularly spend a significant amount of time and money on lessons and devices that are designed to improve the ability and/or score of the player. An avid golfer will invest time and resources specifically to address areas of the game or their swing to improve their ability in that particular area.
One element of the game of golf in which golfers invest a lot of resources is putting. Putting can be one of the most challenging tasks for a golfer. Every stroke saved on the green is crucial to achieving a desirable score. Many golfers invest substantial resources in purchasing lesson specifically focused on putting. Additionally, those golfers will invest hundreds of dollars for a putter that they feel will help them perform better during a game of golf. As is known in the art, golfers will face numerous challenges once the golf ball is in position on the green. Many greens have undulated surfaces that require careful consideration of the putting direction before putting the ball. As greens on golf courses are routinely lined with trees and other landscaping many times the surface of the golf course green can be littered with debris such as but not limited to leaves or twigs.
One problem with the element of putting is that the golfer must contend with and attempt to remove the debris that may be in the predicted putting path of the golf ball. Typically a golfer will attempt to remove as much of the debris as possible in order to eliminate the chance of any debris contacting the golf ball once it has been putted in a given direction. The most common method of removal involves the golfer surveying the predicted putting path and manually removing the leaves or other debris by bending down and retrieving the debris. This method is usually time consuming and can also be problematic for golfers who suffer from back problems.
Accordingly, there is a need for a device that can facilitate the removal of debris from a golf course green more specifically in the predicted putting path of a golf ball that does not require the golfer to bend over and can be performed in a timely manner.

The trigger guard 20 functions to protect the trigger 25 in the event that the golf course green cleaning device 100 is dropped or mishandled.
The trigger 25 is movably mounted to the body 10 and disposed within the trigger guard 20. The trigger 25 is generally arcuate in shape and is manufactured from a suitable durable material such as but not limited to plastic. The trigger 25 is the user interface for the momentary contact switch 30 disposed within the internal volume 9 of the body 10. The user applies a force on the trigger 25 in a direction towards the first end 11 of the body 10 in order to engage the momentary contact switch 30. As is known in the art, a momentary contact switch 30 closes an electrical circuit allowing current to flow therethrough only while the momentary contact switch 30 is engaged. The momentary contact switch 30 disposed within the internal volume 9 of the body 10 is configured as what is known in the art as a normally open switch. When the trigger 25 is in its first position the momentary contact switch 30 is in an open position so as to inhibit current from flowing through the circuit. When the user moves the trigger 25 to its second position the momentary contact switch 30 is now in a closed position which allows current to flow through the circuit. The momentary contact switch 30 is electrically coupled to the power source 40 and the fan motor 50. The momentary contact switch 30 is electrically intermediate the power source 40 and fan motor 50 so as to control the current flow from the power source 40 to the fan motor 50.
Opposite the trigger 25 on the first portion 115 of body 10 is a power switch 77. The power switch 77 is operably coupled to the power source 40 and functions to allow current to flow from the power source 77.

In its second position, the power switch 77 is closed so as to electrically couple the power source 40 with the momentary contact switch 30. In this position the momentary contact switch 30 is activated by the trigger 25 and current will flow to the fan motor 50 thereby rotating the fan 70.
The power source 40 is disposed within the internal volume 9 of the first portion 115 of the body 10 proximate the first end 11. The power source 40 is a conventional rechargeable power source such as but not limited to a lithium ion battery. Those skilled in the art should recognize that numerous different types of batteries could be utilized to manufacture the power source 40. The power source 40 functions to provide current to the fan motor 50 during operation of the golf course green cleaning device 100. The power source 40 includes a first contact 41 and a second contact 42 that are mounted on the exterior surface 8 of the body 10 proximate the first end 11. The first contact 41 and second contact 42 are conventional battery contacts that function to electrically engage with the contacts disposed within the charger 90 so as to receive current therefrom in order to recharge the power source 40.
Integrally formed with the first portion 115 of the body 10 is the second portion 60. The second portion 60 is generally spherical in shape and generally hollow having a cavity 61 therein that is sufficient in size to accommodate the fan 70. The fan 70 disposed within the second portion 60 is a conventional electric fan coupled to the fan motor 50 with a shaft 71. The fan motor 50 functions to rotate the fan 70 in order to produce an airflow that will exit the third portion 116 of the body 10 proximate the second end 12. The second portion 60 includes a first segment 62 that has approximately the same diameter as the first portion 115 of the body 10 proximate thereto. The diameter of the second portion 60 gradually increases towards the midpoint 63 of the second portion 60 whereupon the diameter of the second portion 60 begins to reduce until it reaches the second segment 64 wherein the diameter of the second portion 60 proximate the second segment 64 is equivalent to the diameter of the third portion 116 of the body 10. The shape of the second portion 60 functions to direct the airflow generated by the fan 70 so as to maximize the velocity of the air as it exits the third portion 116 of the body 10 proximate the second end 12.
Located on the second portion 60 between the first segment 62 and the midpoint 63 are a plurality of intake vents 65. The intake vents 65 function to permit air to enter the second portion 60 as it is drawn in by the rotating fan 70 subsequent the fan motor 50 being activated by the momentary contact switch 30 operably coupled to the trigger 25. Those skilled in the art will recognize that the intake vents 65 could be present in numerous different quantities as well as sizes and shapes and still perform the desired function as described herein.
Forward of the second portion 60 is the third portion 116 of the body 10. The third portion 116 is generally cylindrical in shape and hollow. The internal passage 120 of the third portion 116 receives the airflow from second portion 60 and permits the airflow to move towards the second end 12. Proximate the second end 12 circumferentially disposed around the interior of the body 10 are a plurality of threads 27. The threads 27 function to releasably secure the nozzle 80 to the body 10. Those skilled in the art will recognize that numerous different types of fasteners could be utilized to releasably secure the nozzle 80 to the body 10.
The nozzle 80 is generally funnel shaped and manufactured from a suitable durable material such as but not limited to plastic. The nozzle 80 has an interior surface 81 that is generally angular in position. The angularly shaped interior surface 81 of the nozzle 80 functions to disperse the air exiting the golf course green cleaning device 100 at a wider angle of discharge so as to effectively remove debris from a larger swath. A second nozzle 85 is illustrated herein in FIG. 1A. The second nozzle 85 comprises three portions 86 that are telescoping. The outer portion 87 is smallest in diameter and has a diameter that is less than that of the diameter of the third portion 116 of the body 10. The smaller diameter of the outer portion 87 allows a user to apply a greater force of air exiting the golf course green cleaning device 100 to a smaller area, which can be used to remove debris having more mass. While no particular length of the second nozzle 85 is required good results have been achieved utilizing a second nozzle 85 approximately two feet in length. Additionally, those skilled in the art will recognize that the second nozzle 85 could be manufactured from a single tapered segment. Those skilled in the art will recognize that the nozzle 80 and second nozzle 85 could be formed in numerous different shapes and sizes and still perform the desired function as described herein.
