CROSS REFERENCE TO RELATED APPLICATION
This application claims priority to a U.S. Provisional Application No. 61/830,056 filed on Jun. 1, 2013, the entire content of which is incorporated herein by references in its entirety.


BACKGROUND OF THE INVENTION
1. Field of he Invention
The present invention generally relates to a game device related to a footbag and more particularly relates to a game device including a footbag and a gravity-slowing self propelling unit to reduce the skill level required by a player.
2. Description of Related Art
People have always been fascinated with the concept of intercepting a flying object and batting such object back into the air so as to keep such object from reaching the ground. This fascination has resulted in a number of games, such as volleyball, that test a person's skill in keeping a particular object from reaching the ground.
Many games, exercises and devices have been created for developing one's eye-to-foot coordination. In such games and exercises the object is intercepted by the foot and/or knee and kicked repeatedly into the air. Such games and exercises have been found to be extremely helpful in developing not only eye-to-foot coordination, but also the balance and quickness necessary for performing a variety of sports such as baseball, football, basketball, soccer, karate and tennis.
These games and exercises have been found to be especially pleasurable and beneficial when the person performs a wide variety of kicks and is able to kick the object with all parts of the feet and knees. Because the foot and knee generally are not as easily manipulated as the hand, objects suitable for exercises and games wherein the purpose is to keep the object in the air for as long as possible using only the feet and knees must be very light weight and reach the ground as slow as possible to spare time to the player to react and respond well.
Furthermore, the reaction of the object must be consistent and independent of the trajectory in which the object is hit or kicked. In this way, the object may be kicked with the instep, the heel or the toe of the foot and still get a consistent and reliable response. Therefore there is a need for a game device that increases the time spent in the air by the object and makes the reaction of the kick independent of the trajectory in which the object is hit.
SUMMARY OF THE INVENTION
In accordance with the teachings of the present invention, a game device for receiving impacts from a user during recreational activities that increases the time spent in air by the object is provided.
An object of the present invention is to provide the game device including a flexible closure for receiving impacts from the user, one or more filler placed inside the flexible closure for reducing recoiling of the flexible closure from the surface on receiving impacts, a mechanical unit attached to the inner walls of the flexible closure and a gravity slowing unit attached to the mechanical unit for reducing the gravitational pull acting on the flexible closure.
The mechanical unit includes an electric motor for providing torque, an impact sensor for sensing the impacts received from the user, and a power source for energizing the electric motor and the impact sensor. The gravitational slowing unit includes a spring-loaded hinge for stabilizing the flexible closure from impacts projected by the user, a spring-loaded shaft connected to the electric motor through the spring-loaded hinge for rotating on receiving torque from the electric motor, at least one set of propellers connected to the spring-loaded shaft for receiving torque and providing thrust against gravitational pull acting on the flexible closure.
Another object of the present invention is to provide either sand or pallets as filler for filling the flexible closure to reduce the recoiling. Further, the spring-loaded hinge is a ball hinge. Furthermore, another object of the present invention is to provide a game device wherein the impact sensor disables the propellers for a predetermined duration on sensing gravitational pull on the flexible closure.
Another object of the present invention is to provide an output unit to play audio/visual and controlled by impact sensor. Further, the gravity slowing unit includes a ring for circumscribing the at least one set of propellers. The ring covers the propellers to ensure safety of the user from getting injured.
These and other features and advantages will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.

FIG. 1 illustrates an exploded view of a game device 100. The game device 100 includes a flexible closure 102, one or more filler 104, a mechanical unit 104 and a gravity slowing unit 106. The flexible closure 102 receives impacts from the user. In a preferred embodiment of the present invention, the flexible closure 102 is a footbag to receive impact from the foot of the user. The user kicks in a way to move the flexible closure 102 in upward direction. The flexible closure 102 is explained in detail in conjunction with FIG. 2 of the present invention.
The one or more filler 104 such as 104a, 104b and 104c are placed inside the flexible closure 102 for reducing recoiling of the flexible closure 102 from the surface on receive impacts from the user. In a preferred embodiment of the one or more filler 104 is sand. However it will be readily apparent to those skilled in the art that many other filler 104 may also be envisioned without deviating from the scope of the present invention.
The mechanical unit 106 is attached to the inner walls of the flexible closure 102. The mechanical unit 106 includes an electric motor 108 for providing torque, an impact sensor 110 for sensing the impacts received from the user and a power source 112 for energizing the electric motor 108 and the impact sensor 110. The power source 112 and the impact sensor 110 are explained in detailed in conjunction with FIG. 2 of the present invention.
The gravity slowing unit 106 is attached to the mechanical unit for reducing the gravitational pull acting on the flexible closure 102.

FIG. 3 illustrates a game device 300 receiving impact from a user 302 in accordance with an exemplary embodiment of the present invention. The user 302 kicks the fixed closure 102, and the impact sensor detects the impact on the fixed closure 102 and results in activation of the propellers 118 via the electric motor. Further, the thrust produced by at least one set of propellers 118 facilitates in keeping the flexible closure 102 in air for longer duration by reducing the weight.
FIG. 4 illustrates a game device 300 with disabled propellers 118 in accordance to another exemplary embodiment of present invention. The impact sensor 110 may be pre-programmed to disable the propellers 118 after a certain period of time. For example, the impact sensor 110 disables the propellers 118 through the electric motor 108 after 10 seconds of receiving the impact from the user 302 for providing stability to the flexible closure 102 and to enhance the game play.
In another exemplary embodiment of the present invention, the impact sensor 110 disables the propellers 116 after 10 seconds of receiving the impact from the user 302 for 5 seconds to provide stability to the flexible closure 102 and enhance the game play. However, it would readily apparent to those skilled in the art that other time duration may also be envisioned without deviating from the scope of the present invention.
