DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-6, the present invention features a random number selector device 100 for generating random numbers for lotteries or other purposes. The random number selector device 100 of the present invention comprises a generally spherical and hollow globe 110 having a top end, a bottom end, and an inner cavity. A plurality of globe air apertures 118 is disposed in the top end of the globe 110. In some embodiments, the bottom end of the globe 110 is open. In some embodiments, globe air apertures are disposed in the bottom end of the globe 110. The inner cavity is for housing a plurality of balls 150. The balls 150 are each labeled with a number. The balls 150 are equal in weight and size.
The device 100 of the present invention further comprises a base 120 for supporting the globe 110. The base 120 has a top surface, a bottom surface, side surfaces, and an inner cavity. In some embodiments, a concave indentation 126 is disposed in the top surface of the base 120 to accommodate the globe 110 (the bottom end of the globe 110). FIG. 2 is a side cross sectional view of the device 100 of the present invention showing the bottom end of the globe 110 positioned in the concave indentation 126. A plurality of base air apertures 128 is disposed in the concave indentation 126. The base air apertures 128 allow flow of air from the inner cavity of the base 120 into the inner cavity of the globe 110 (e.g., via the open bottom end of the globe 110 or via globe air apertures in the bottom end of the globe 110). The flow of air causes the balls 150 in the inner cavity of the globe 110 to randomly move around. Air an exit the inner cavity of the globe via the globe air apertures 118.
Disposed in the inner cavity of the base 120 is a fan 210 operatively connected to a motor 220. The fan 210 and motor 220 function to push air out of the base 120 via the base air apertures 128 (and into the inner cavity of the globe 110). As shown in FIG. 6, a plurality of side apertures 129 is disposed in a side, surface of the base 120. The side apertures 129 allow air to be drawn into the inner cavity of the base 120.
The motor 220 is operatively connected to a power source. In some embodiments, the power source is a battery. In some embodiments, the power source is an electrical outlet (e.g., a power cord operatively connects the motor 220 to an electrical outlet. In some embodiments, a battery compartment 230 is disposed in the base 120 for housing one or more batteries. The device 100 also features a power switch 240 for turning the device on and off. The power switch 240 may be disposed on the base 120.
The device 100 of the present invention further comprises a hollow selector tube 310 that extends out of the globe 110, for example a side area of the globe 110. For example the first end 311 of the selector tube 310 is attached to, the globe 110. The selector tube 310 is fluidly connected to the inner cavity of the globe 110. The selector tube 310 allows passage of a ball 150 out from the inner cavity of the globe 110 (e.g., the selector tube 310 is sized to allow passage of a ball 150 from the inner cavity of the globe 110 through the selector tube 310 and out of the second end 312 of the selector tube 310). In some embodiments, the selector tube 310 is removably attached to the globe 110. In some embodiments, the selector tube 310 is pivotally attached to the globe 110, allowing a user to position the tube 310 appropriately. The selector tube 310 may be generally curved (e.g., as shown in FIGS. 1 and 3), for example the selector tube may be curved with the contour of the shape of the globe 110. In some embodiments, a connector piece 319 connects, an area of the selector tube 310 at or near the second end 312 to the globe 110 (e.g., for stability).
As shown in FIG. 2, in some embodiments, a cap 330 is disposed on the second end 312 of the selector tube 310. In some embodiments, one or more cap apertures are disposed in the cap 330 allowing air to flow out from the tube 310. The cap 330 may be removably attached to the outer end of the selector tube 310.
A tube cover 350 is disposed in the globe 110 at the intersection of the first end 311 of the selector tube 310 and the globe 110. The tube cover 350 functions to temporarily block access to the selector tube 310. The tube cover 350 can pivot between a first position and a second position respectively allowing and preventing access to the selector tube 310 (e.g., not covering and covering the first end 311 of the selector tube 310, respectively). The tube cover 350 is biased in the second position caused by a spring 318 (e.g., the tube cover 350 is a spring-loaded cover). A release lever 360 is attached to the tube cover 350. The release lever 360 extends outwardly from the selector tube 310 and globe 110. The release lever 360 can be pushed, causing the tube cover 350 to move to the first position (allowing access to the selector tube 310). When the release lever 360 is released, the spring 318 causes the tube cover 350 to move back to the first position (preventing access to the selector tube 310).
To use the device 100, the balls 150 are place in the inner cavity of the globe 110. The device 100 is turned on (via the control switch 240) and air is directed through the inner cavity of the globe 110. The air causes the balls 150 to move around randomly. Because the tube cover 350 covers the selector tube 310, no balls 150 can escape. If a user presses the release lever 360 to move the tube cover 350 to the first position, balls can escape into the selector tube 310, creating a series of randomly chosen numbers for a lottery or other game. After selecting balls, the device can be turned off and the release lever 360 can be moved to allow the balls to return into the globe 110 to be ready for the next use.
Without wishing to limit the present invention to any theory or mechanism, it is believed that the present invention is advantageous because the present invention comprises a tube, release lever, and battery compartment, and the slant of the tube allows for easy ball release back into the globe.
