The present invention relates to the field of the athletic game of golf. Generally, the present invention relates to the configuration of a golf course on which a round of golf is played, and, more particularly, to the installation of golf hole cups on the putting greens of a golf course. Specifically, the present invention provides a golf hole cup to replace conventional golf hole cups, which comprises a golf ball elevator for returning a golf ball to a golfer after successfully stroking his or her golf ball into the hole.
Typically, holes on the greens of a golf course are provided by digging a cylindrical hole and installing a golf hole cup in the hole.
As shown in
The cup 20 is cylindrical, with an outside radius 28, and is customarily inserted into the ground G until the top rim 50 of the cup is a distance 52 below the putting surface S of the golf course putting green, producing an earthen hole rim 54 at the top of the hole 11. USGA regulations specify that the distance 52 is about 1.5 inches, which is therefore also the height of earthen hole rim 54. The ferrule 16 is inserted into the aperture 22 until a ferrule collar 19 engages a cup aperture rim 26. When inserted into the aperture 22, ferrule side elements 18 engage the inside surface 24 of the aperture 22. The aperture inside surface 24 is defined about a radius 30 aligned with the outside radius 28 of the cup 20. The ferrule side elements 18 are similarly defined substantially about a radius 32, which is aligned normal to the cylindrical flagstick 12 centerline C.
The ferrule side element radius 32 is slightly smaller than the aperture radius 30, thereby enabling easy insertion and removal by a golfer of the ferrule 16 from the aperture 22. By engaging the ferrule side elements 18 with the aperture inside surface 24, and the ferrule collar 19 with the cup aperture rim 26, the cup 20 holds the flagstick 12 in a vertical fashion, with the flagstick centerline C substantially normal to the cup 20 radius 28.
The flagstick 12 is typically fiberglass, with popular outside diameter dimensions of ½ or ⅝ inch. Fiberglass flagsticks 12 of these dimensions are preferred by most golf courses since they are lightweight, durable, and rigid.
A golfer may stroke his or her golf ball into the cup 20 while be or she is off the putting green when the flagstick 12 is in the cup. It is important that the flagstick 12 allows a golf ball to fall into the cup 20 while the flagstick is still inserted into the cup 20. With a typical inside diameter 40 of about 4.25 inches, a conventional USGA cup 20 has space within the golf ball engaging area 42 within the cup to accommodate the flagstick 12 and allow a USGA regulation golf ball to fall into the cup. On the other hand, if the golfer has stroked his or her golf ball onto the putting green without entering the cup 20, the flagstick 12 is typically removed from the cup, and the golfer putts his or her golf ball one or more times until the ball falls into the cup.
In either case, in order for the golfer to retrieve his or her golf ball after stroking the ball into the cup 20, the golfer typically bends down and plucks the ball out of the cup by hand. Often, the golfer stands over the hole 11 on one leg, with his or her other leg lifted off the putting green and extended behind the golfer for balance as the golfer bends and reaches into the cup 20 to retrieve his or her golf ball. Such a maneuver may be a difficult task for many golfers and increases the risk of the golfer losing his or her balance and staggering, or even falling down. Also, bending over by arching the spine during the process of removing the golf ball from the cup 20 is uncomfortable for some golfers, especially those with back problems.
The present invention has as an object to provide a device to facilitate the retrieval of a golf ball after the ball is stroked by a golfer into a golf hole cup. Various examples of the device in accordance with the present invention provide a golf ball elevator incorporated into a golf hole cup to return the golf ball to the golfer after the ball falls into the cup so that the golfer does not need to bend over to retrieve his or her ball, thereby avoiding the risk of experiencing discomfort or falling down when retrieving his or her golf ball.
One example of the golf ball elevator in accordance with the present invention comprises a motorized telescoping shaft assembly. The motorized telescoping shaft assembly is preferably mounted to the webbing of a conventional golf hole cup. The telescoping shaft is coupled to a cylindrical cup element to receive and retain a golf ball stroked into the golf hole. The cylindrical cup element has an aperture through which a flagstick may be extended into the aperture in the webbing of a conventional golf hole cup incorporating the golf ball elevator. The cylindrical cup element is spring mounted to a plate which is attached to the telescoping shaft and also has an aperture through which the flagstick may be extended into the aperture in the webbing of the conventional golf hole cup incorporating the golf ball elevator. An electrical switch is mounted to the plate and is actuated when the weight of a golf ball in the cylindrical cup element causes the springs to be compressed to actuate the motor of the motorized telescoping shaft assembly to elevate the cylindrical cup element containing the golf ball until the telescoping shaft is fully extended. The golfer may then conveniently and comfortably remove his or her golf ball from the cylindrical cup element.
When the golfer removes the golf ball from the cylindrical cup element, the electrical switch which is actuated by the weight of the golf ball is deactuated so that the motor is actuated to reverse and lower the spring mounted cylindrical cup element and plate assembly to return the assembly into the golf hole cup.
In accordance with a second example, the golf ball elevator incorporated into the golf hole cup comprises a cylindrical shaft which may, for example, be three feet in length, coupled to a motor housed in a golf hole cup to move the shaft up and down along a coaxial rod interior of the cylindrical shaft. The exterior of the cylindrical shaft has gear teeth along the length of the shaft. The golf hole cup comprises a cylindrical cup element to receive and retain a golf ball stroked into the golf hole. The cylindrical cup element has an aperture through which a flagstick may be extended into the aperture in the webbing of a conventional golf hole cup incorporating the golf ball elevator. The cylindrical cup element is spring mounted to a plate which is attached to the shaft and also has an aperture through which the flagstick may be extended into the aperture in the webbing of the conventional golf hole cup incorporating the golf ball elevator. An electrical switch is mounted to the plate and is actuated when the weight of a golf ball in the cylindrical cap element causes the springs to be compressed to actuate the motor to drive a gear connected to the shaft of the motor and meshed with the gear teeth along the cylindrical shaft to elevate the cylindrical cup element containing the golf ball until a limit switch deactuates the motor when the cylindrical shaft is fully extended. The golfer may then conveniently and comfortably remove his or her golf ball from the cylindrical cup element.
When the golfer removes the golf ball from the cylindrical cup element the electrical switch which is actuated by the weight of the golf ball is deactuated so that the motor is actuated to reverse rotation of the gear connected to its shaft and lower the spring mounted cylindrical cup element and plate assembly to return the assembly into the golf hole cup.
In accordance with yet another example, the gear assembly of the second example may be replaced by a pulley assembly to raise and lower the cylindrical cup element and plate assembly.
The various examples of the present invention will be described in conjunction with the accompanying figures of the drawing to facilitate an understanding of the present invention. In the drawing:
As shown in
The golf ball elevator assembly 300 also comprises a cylindrical cup element 410 to receive and retain a golf ball 444 stroked into the golf hole 11. The cylindrical cup element 410 has an aperture 411 through which the flagstick 12 may be extended into the aperture 22 of the conventional golf ball cup 20 shown in
An electrical switch 428 connected to the motorized telescoping shaft assembly 302 by electrical wiring 424 is mounted to the plate 421 and is actuated when the weight of the golf ball 444 in the cylindrical cup element 410 causes the springs 418 to be compressed to actuate the motorized telescoping shaft assembly to elevate the cylindrical cup element containing the golf ball until the motorized telescoping shaft assembly is deactuated when the telescoping shaft 312 is fully extended.
The springs 418 have a spring constant equivalent to the tension force of the weight of the golf ball 444. Consequently, when a golfer strokes his or her golf ball 444 into the golf hole 11, the springs 418 are compressed to actuate the switch 428 to cause the motorized telescoping shaft assembly 302 to raise the cylindrical cup element 410 containing the golf ball 444 three or four feet or any comfortable height with the aid of the shaft 312. For example, the cylindrical cup element 410 containing the golf ball 444 may be elevated to a distance which is preferably three feet above the surface of the putting green. The golfer may then conveniently and comfortably remove his or her golf ball 444 from the cylindrical cup element 410. When the golfer removes his or her golf ball 444 from the cylindrical cup element 410, the springs 418 are in tension, and the switch 428 is switched so that the motorized telescoping shaft assembly 302 is actuated to lower the cylindrical cup element 410 and plate 421 assembly with the aid of the telescoping shaft 312.
As shown in
Because the shaft 312 can be telescopic, the length of the golf ball elevator assembly 300 can be approximately one foot. This enables the golf ball elevator assembly 300 to be portable for use on golf courses. The motorized telescoping shaft assembly 302 can be implemented by modifying a motorized antenna module such as shown in U.S. Pat. No. 4,236,162 or a commercially available Model PA-03 fully automatic “mini” power antenna marketed by Retro Manufacturing, LLC, located in Henderson, Nev.

The golf ball elevator assembly 400 also comprises a cylindrical cup element 410 to receive and retain a golf ball 444 stroked into the golf hole 416. The cylindrical cup element 410 has an aperture 411 through which a flagstick 413 may be extended into an aperture 415 which is preferably the same as the aperture 22 of the conventional golf hole cup 20 shown in
An electrical switch 428 connected to the motor 414 by electrical wiring 424 is mounted to the plate 421 and is actuated when the weight of the golf ball 444 in the cylindrical cup element 410 causes the springs 418 to be compressed to actuate the motor 414 to drive the gear 438A connected to the shaft of the motor and meshed with the worm wheel 438B which in turn is meshed with the gear teeth 438C along the length of the shaft 412 to elevate the cylindrical cup element containing the golf ball until a limit switch 423 actuated by a projection 425 at the base of the shaft deactuates the motor when the shaft is fully extended.
The springs 418 have a spring constant equivalent to the tension force of the weight of the golf ball 444. Consequently, when a golfer strokes his or her golf ball into the golf hole 416, the springs 418 are compressed to actuate the switch 428 that causes the golf ball elevator assembly 400 to raise the cylindrical cup element 410 containing the golf ball 444 three or four feet or any comfortable height with the aid of the shaft 412. For example, the cylindrical cup element 410 containing the golf ball 444 may be elevated to a distance which is preferably three feet above the surface of the putting green. The golfer may then conveniently and comfortably remove the golf ball 444 from the cylindrical cup element 410. When the golfer removes his or her golf ball 444 from the cylindrical cup element 410, the springs 418 are in tension, and the switch 428 is switched so that the motor 414 is actuated to lower the cylindrical cup element 410 and plate 421 assembly with the aid of the shaft 412.
As shown in
The golf ball elevator assembly 400 including the housing 430 can be constructed from any kind or combination of materials, for example, metal or plastic or any other materials that are suitable. Preferably, materials are selected which are lightweight so that the golf ball elevator assembly 400 can be easily carried and moved around. With the golf ball elevator assembly 400 shown in
As shown in
The electrical switch 428 connected to the motor 414 by electrical wiring 424 is mounted to the plate 421 and is actuated when the weight of the golf ball 444 in the cylindrical cup element 410 causes the springs 418 to be compressed to actuate the motor to drive the pulley 534A connected to the shaft of the motor coupled by the belt or cable 532 to the pulley 534B to elevate the cylindrical cup element containing the golf ball until the limit switch 423 is actuated by the cleat 536 to deactuate the motor when the shaft 512 is fully extended.
The springs 418 have a spring constant equivalent to the tension force of the weight of the golf ball 444. Consequently, when a golfer strokes his or her golf ball into the golf hole 416, the springs 418 are compressed to actuate the switch 428 that causes the golf ball elevator assembly 400 to raise the cylindrical cup element 410 containing the golf ball 444 three or four feet or any comfortable height with the aid of the shaft 512. For example, the cylindrical cup element 410 containing the golf ball 444 may be elevated to a distance which is preferably three feet above the surface of the putting green. The golfer may then conveniently and comfortably remove the golf ball 444 from the cylindrical cup element 410. When the golfer removes his or her golf ball 444 from the cylindrical cup element 410, the springs 418 are in tension, and the switch 428 is switched so that the motor 414 is actuated to lower the cylindrical cup element 410 and plate 421 assembly with the aid of the shaft 512 coupled to the belt or cable 532 driven by the pulleys 534A and 534B. Preferably, all of the components are mourned in the housing 430 for waterproof protection and portability.
As shown in
The various examples of the golf ball elevator in accordance with the present invention have many advantages. The golf ball elevator including the motorized telescoping shaft 312 or the motor 414 and shaft 412 or 512 enable a golfer to retrieve his or her golf ball easily at a comfortable height, reducing the risk of stumbling and/or falling down when retrieving the golf ball from the golf hole cup.
Additionally, the golf ball elevator in accordance with the present invention can be installed on all golf course holes, and all of the eighteen holes can be connected to each other with electrical wiring 520 and computer cable 522 connected to a main CPU 526 to track play on the golf course and control advertising, displaying a company name and logo or other branding, or messaging. The golf ball elevator incorporated into the golf hole cup being the prime spot of the golf course to focus all eyes from fans makes this the prime location for advertising and/or messaging with the aid of the golf ball elevator. In accordance with one example, the golf ball elevator can be utilized as a sign board for advertising when in the raised position. In accordance with another example, the golf ball elevator can incorporate a digital display element mounted to the shaft 312, 412, or 512 which can be computer controlled to display digital images. For example, the shaft 412 or 512 can be formed with four sides (square) having digital displays to facilitate digital images used for advertising when in the raised position. Additionally, a loudspeaker can be incorporated into the golf ball elevator, and the CPU 526 can supply the loudspeaker with audio for music before and after the golf match, for example, the fourth of July and Christmas, and/or broadcast announcements during the golf match.
Also, the shaft 312, 412, or 512 can incorporate a computer controlled display to display which score was achieved by the golfer who stroked his or her golf ball into the golf hole cup, e.g., a hole in one, eagle, birdie, bogie, double bogie, etc. The computer controlled display incorporated into the shaft 312, 412, or 512 can also display images to instruct how to play the game of golf so that spectators and viewers of televised tournaments can more easily understand golf.
The examples described above are provided by way of example only, and various modifications which will be apparent to persons skilled in the art are contemplated. For example, the golf ball elevator may be powered by a pneumatic motor or hydraulic motor. Also, the golf ball elevator may alternatively be remotely controlled by computer. Accordingly, the scope of the present invention can only be ascertained with reference to the appended claims.
