BACKGROUND OF THE INVENTION
The invention relates to a golf ball teeing up device, and more particularly, to an automatic golf ball teeing up device for teeing up a golf ball so that the golfer does not have to bend over and tee the ball after each swing.
Golfing is a pastime enjoyed by many Americans. Whether it is playing golf competitively or just for leisure, Americans continue to invest much time, energy, and money into joining golf clubs, taking golf lessons, and practicing their swing at driving ranges. Golfing offers its players the advantage of moderate exercise, while spending time outdoors enjoying beautifully groomed courses. In addition, swinging the many different clubs, carrying the bag of golf clubs, and walking the golf course also provide players with moderate levels of physical fitness. Many avid golfers enjoy spending time at driving ranges where they can practice their swing over and over again. At such facilities, a player usually purchases a bucket of golf balls and hits them one at a time off of the tee into a large fenced-in landscape. In between each swing, the golfer must bend over, retrieve another golf ball, and properly set it on the tee. This action causes the golfer to move their feet and take their hands off of the golf club, and for each swing the golfer must then re-grip their club and readjust their stance.
U.S. Pat. No. 5,603,664 to Provost discloses a golf ball teeing-up apparatus that has a detector underneath the tee for detecting the presence of a golf ball on the tee to tee-up another golf ball when needed. U.S. Pat. No. 5,356,148 to Elder, Jr. discloses a mechanism for automatically teeing practice golf balls, using a manually operated switch which causes the teeing mechanism to retract and receive another golf ball. U.S. Pat. No. 5,916,033 to Doherty discloses a golf ball teeing-up device that has a control switch that is manually tapped by a golf club sole to initiate the teeing-up.
While these units may be suitable for the particular purpose employed, or for general use, they would not to be as suitable for the purposes of the present invention as disclosed hereafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates an automatic golf ball teeing up device 18 for simply and conveniently teeing up a golf ball at a driving range or golf course, or similar facility, so that a golfer does not have to bend over and tee the golf ball after each swing. The driving range has a playing green having a foundation 23 just above a ground level 22. Artificial turf 24 is positioned on top of the foundation 23.
A rectangular base plate 20 has a top surface 21 which lies horizontally below the foundation 23. An artificial turf 24 is attached to the foundation 23. A circular cutout 40 extends through the artificial turf 24, foundation 23, and rectangular base plate 20. A chamber assembly 41 having a cylindrical chamber 43 extends downwardly from the circular cutout 40, perpendicular to the rectangular base plate 20. A locknut 48 attaches the cylindrical chamber 43 to the rectangular base plate 20. The cylindrical chamber 43 has a loading chamber 42 therein, and a retainer ring 45 extending therein. The retainer ring 45 holds one golf ball at a time thereon prior to being teed up.
A holding cage 25, for holding a plurality of golf balls therein, includes a bottom surface 28. The bottom surface 28 of the holding cage 25 has an opening 30 which rests against the foundation 23 or artificial turf 24. A tube 26, preferably a polyvinyl chloride tube, is attached to the opening 30 at the bottom surface 28 of the holding cage 25 and extends downwardly at a slight incline through the cylindrical chamber 43 and into the loading chamber 42. The tube 26 is welded into the cylindrical chamber 43, preferably using a polyvinyl chloride weld 27. The tube 26 is slightly larger in diameter than a golf ball for holding the golf balls in a single file line therein. The tube 26 gravity feeds the golf balls from the holding cage 26 in a single file line one at a time down onto the retainer ring 45 within the loading chamber 42.
A pair of holding cylinders 32, including a first holding cylinder 32A and a second holding cylinder 32B, bisect the tube 26 and are used to hold back the golf balls within said tube 26 so that the golf balls back up behind one another and are only allowed to pass into the loading chamber 42 one at a time. Each holding cylinder 32A and 32B includes a solenoid valve 34, including a first and second solenoid valve 34A and 34B, for controlling up and down movements of the holding cylinders 32. Preferably, the holding cylinders 32 are driven by compressed air and threaded into the tube 26 one and three-fourths inches apart. Working opposite one another, the holding cylinders 32 allow only one golf ball to pass at a time.
The chamber assembly 41 includes a vertical axis 44. A pneumatic cylinder device 50 fits within the cylindrical chamber 43. A circular base cap 46 holds the pneumatic cylinder device 50 axially aligned along the vertical axis 44 of the chamber assembly 41. The golf ball in position on the retainer ring 45 is axially aligned along the vertical axis 44. The pneumatic cylinder device 50 has a main cylinder 52 having a piston rod 54 mounted therein and a piston head 56. Preferably, the main cylinder 52 is driven by compressed air. The piston rod 54 includes a top end 54T, and is raised and lowered in a telescoping manner from within the main cylinder 52. The main cylinder 52 of the pneumatic cylinder device 50 has an upper end 52U and a lower end 52L. The piston head 56 has a top side 56T and a bottom side 56B. A down port 58 and an up port 59 extend outwardly from the upper end 52U and the lower end 52L respectively. The down and up ports 58 and 59 supply compressed air pressure, preferably through plastic tubing, to the top and bottom sides 56T and 56B of the piston head 56. The main cylinder 52 is substantially air tight so that when air pressure is increased through the upper end 52U on the top side 56T of the piston head 56, said piston head 56 is forced downwardly thereby withdrawing the piston rod 54 into the loading chamber 42 and into the main cylinder 52. When air pressure is increased through the lower end 52L on the bottom side 56B of the piston head 56, said piston head 56 is raised thereby extending the piston rod 54 upwardly through the loading chamber 42 and the circular cutout 40. The down port 58 is connected, preferably by plastic tubing, to the second: solenoid valve 34B within the second holding cylinder 32B. The up port 59 is connected, preferably by plastic tubing, to the first solenoid valve 34A within the first holding cylinder 32A.
A tee 60 is attached to the top end 54T of the piston rod 54. A bolt is fitted within the tee 60 and is attached to an attaching nut 47. The attaching nut 47 is then fitted onto a coupling and onto the top end 54T of the piston rod 54. The tee 60 is preferably made of rubber.
A photoelectric sensor device 70 has a photoelectric sensor 71 having a photoelectric eye 72 and a reflector 74, the photoelectric sensor 71 is in communication with a timer 80 and a relay 82, shown in FIGS. 4 and 6. An electrical circuit 70A is illustrated including electronically connecting the photoelectric sensor 71, the relay 82, timer 80, and the first and second solenoid valves 34A and 34B are shown in FIG. 6. In FIG. 1, the photoelectric eye 72 is mounted to the foundation 23. The reflector 74 is attached by a spring loaded hinge 76 to the foundation 23 near or on the artificial turf 24, shown in FIG. 5. The photoelectric eye 72 is axially aligned along an axis 78 with the reflector 74 as shown in FIG. 4. The photoelectric eye 72, of the photoelectric sensor 71 connects in communication with the reflector 74 along the axis 78. The golf ball 100 on the tee extends upwardly through the circular cutout 40 along the axis 78 between the photoelectric eye 72 and the reflector 74, illustrated in FIG. 4. When the golf ball 100 is in position on the tee the photoelectric eye 72 is interrupted, or no longer connected to the reflector 74, shown in FIG. 4, causing the relay to reset the timer. Interrupting the photoelectric eye 72 allows the photoelectric sensor 71 to sense the presence of the golf ball 100 on the tee. Once the golfer takes a swing and hits the golf ball 100 off of the tee, the photoelectric eye 72 of the photoelectric sensor 71 connects with the reflector 74, and the photoelectric sensor 71 then triggers the timer from the absence of a teed up golf ball.
FIGS. 2 and 3 illustrate the teeing up device 18 for the invention in use wherein pair of solenoid valves within the pair of holding cylinders alternate energizing and de-energizing to allow one golf ball to pass therethrough and be teed up at a time. FIG. 2 illustrates the photoelectric sensor 71 being triggered with the photoelectric eye 72 connects with the reflector 74 and causes a down stroke position to be actuated. The golf ball 100, which originated in the holding cage and traveled downwardly through the tube 26, is positioned between the first and second holding cylinders 32A and 32B. The timer 80 and relay 82, shown in FIG. 5, control the pair of solenoid valves within the holding cylinders, which in turn are connected to the down and up ports 58 and 59 within the chamber assembly 41. The relay 82 is used to isolate and reset the timer 80 as shown in FIG. 5. Further referring to FIG. 5, then the photoelectric eye 72 connects with the reflector 74, the photoelectric sensor 71 is triggered and the timer 80 is actuated by the relay 82 and energizes the first solenoid valve 34A in the first holding cylinder to be pulled inwardly into the first holding cylinder in a down stroke. In FIG. 2, when this occurs air pressure is increased on the top side 56T of the piston head 56 by traveling into the down port 58 on the lower end 52L of the main cylinder 52. This forces the piston head 56 downwardly thereby withdrawing the piston rod 54 into the loading chamber 42 and into the main cylinder 52. Then, the timer 80 counts for 1.6 seconds in order to allow the golf ball 100 to roll from the tube 26 into loading chamber 42 of the cylindrical chamber 43 and onto the retainer ring 45.
After 1.6 seconds, the timer 80 de-energizes the first solenoid valve 34A, and energizes the second solenoid valve 34B thereby causing an up stroke position to be actuated, shown in FIG. 3. Here, the second solenoid valve 34B is energized and pushes downwardly into the second holding cylinder 32B in a down stroke, thereby allowing the golf balls within the tube 26 to pass. However, because the first solenoid valve 34A is moved upwardly, the plurality of golf balls within the tube 26 are stopped and prohibited from passing the first solenoid valve 34A. Once energized, the second solenoid valve 34B, connected to the up port 59, causes air pressure to increase through the up port 59 on the lower end 52L of the main cylinder 52, to the bottom side 56B of the piston head 56. The piston head 56 is raised thereby extending the piston rod 54 upwardly through the loading chamber 42 and the circular cutout 40. The piston rod 54, with tee 60 attached thereto, raises up through the loading chamber 42, through the retainer ring 45 and pushes the golf ball 100 on the retainer ring 45 upwardly therewith, thereby teeing up the golf ball 100. Once the photoelectric sensor 71 is disrupted by the photoelectric eye 72 no longer connecting with the reflector 74, the photoelectric sensor 71 triggers the relay to reset the timer.
In conclusion, herein is presented an automatic golf ball teeing up device. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
