the present invention is directed to a golf cup modified to have a lifting device which propels the cup out of the golf hole subsequent to the ball landing in the cup . in a preferred embodiment , the lifting device resembles an automobile automatic antenna . thus , the lifting device consists of a small dc ( ac ) electrical motor and drive assembly . they are fed either locally via , if its in a self - contained can battery or centrally from battery , ac system or uninterruptible power source ( ups ) system ( if it &# 39 ; s part of a golf range or training center . the motor is connected to the antenna stationary tube which is covering the antenna mast . a ball holder and a small contact or pressure switch are located on top of the antenna mast . in this embodiment of the present invention , the lifting system is mounted as part of the can under the golf hole . when a balls falls in the hole and into the ball holder , the golf ball hits the pressure switch or contact . when the golf ball hits the switch or contact ( the electrical circuit is closed ), the lifting device immediately activates and elevates the golf ball to the predetermined height determined according the manufacturer &# 39 ; s specifications for that particular power antenna . a preferred embodiment of the lifting device is a telescoping power antenna which extends and retracts by a reversible electric motor . the antenna is controlled by an external relay and automatic limiting switches built into the electric motor housing . the electric motor extends the antenna mast to maximum length and then is declutched by the limiting switches . the antenna automatically raises when a golf ball falls into the golf cup contacting the pressure switch . the antenna automatically retracts upon removing the golf ball from the golf cup . the placement of the switch is such that the switch is basically in the middle of the cup so that the ball rests completely on the switch until the ball is removed . the following is given for the purpose of illustrating various embodiments of the invention and are not meant to limit the present invention in any fashion . with reference to fig1 golf ball 2 is shown as placed in golf holder or cup 4 . like most golf cups , the modified golf cup of the present invention would have at least one drainage hole 6 . the modified golf holder or cup 4 has a electric pressure switch 8 located near the base of the cup 4 . the embodiment of the modified golf cup of the present invention shown in fig1 illustrates a wire 10 from the pressure switch to the power source . fig2 illustrates an embodiment of the present invention in both the elevated and recessed positions . a golf ball 2 is shown as placed in golf holder or cup 4 . attached to the golf holder or cup 4 is an antenna mast 12 which arises out of stationary tube 14 . the modified golf holder or cup 4 has a electric pressure switch 8 . the stationary tube 14 is connected to an electric motor 16 having a standard power source 18 . the entire power driven modified golf cup and apparatus is housed in a can 20 placed into a hole 22 in the ground . a wire 20 connects the pressure switch to the electric power source . any patents or publications mentioned in this specification are indicative of the levels of those skilled in the art to which the invention pertains . these patents and publications are herein incorporated by reference to the same extent as if each individual publication was specifically and individually indicated to be incorporated by reference . one skilled in the art will readily appreciate that the present invention is well adapted to carry out the objects and obtain the ends and advantages mentioned , as well as those inherent therein . the present examples along with the methods , procedures , treatments , molecules , and specific compounds described herein are presently representative of preferred embodiments , are exemplary , and are not intended as limitations on the scope of the invention . changes therein and other uses will occur to those skilled in the art which are encompassed within the spirit of the invention as defined by the scope of the claims .
the present invention provides a modified golf cup comprising : a golf cup ; and means for reversibly elevating said cup in response to a golf ball entering said cup . in a preferred embodiment , the modified golf cup has a power - driven lifting means for reversibly elevating said cup .
