ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to the sport of golf, and more particularly to golf cars or carts and golf club carriers.
On a golf course, golfers often carry their own golf clubs in a golf club bag. The golfers may walk the entire course with the golf club bag held by a strap swung over their shoulder. A typical set of golf clubs may include 12 golf clubs or more. The set of clubs thus is often heavy and cumbersome to carry over an entire course. A caddie may accompany the golfer to aid in carrying the golf clubs.
Wheeled golf club carriers, also known as pull or push carts, have been developed to permit golfers to wheel their clubs over the course, by pulling the carrier by hand. The golf club carriers typically permit a golf bag to be attached by straps, and the golf bag is thus transported over the entire golf course by the golfer pulling or pushing the carrier. Such manual golf club carriers and the associated walking of the entire course however lead to slow golf games, which can be a major problem on popular golf courses. Moreover, some golfers fatigue or are incapable of walking an entire golf course, which can require 4 kilometers of travel or more.
Motorized golf cars capable of carrying two golfers and having a golf bag bay for carrying the golfers golf bags and typically having electric or internal-combustion motors, also are known. These golf cars are known colloquially as golf carts, and the two terms are used interchangeably herein. Some courses even require such carts to speed golf play. These motorized golf carts typically move along specially-designated areas, or cart paths, on the golf course so that golfers can proceed with ease quickly throughout the golf course. Some golf courses permit golf carts to travel not just on the cart paths, but also over the entire course, including fairways. However, this travel can damage the golf course. For example, when a fairway is wet, the golf carts can leave muddy track marks on the fairway or even on the greens. For this reason, many golf courses confine motorized golf carts to the cart paths.
When using a motorized golf cart, golfers typically place their golf bags in the golf cart, so that the bags rest on a horizontal surface of a bag bay. The golf bags then are strapped in. The golfers do not remove the bags during play, since the bags with the clubs are heavy and the golf bag must be lifted to be strapped in. Typically, the bottom of the bag sits at least 0.3 meters from the ground, and the straps are even higher. The lifting of the golf bag in the first place is also burdensome.
On a course where the motorized golf carts are confined to the cart paths, golfers without caddies typically golf as follows: (1) The golfer drives his cart to a tee, decides what club to use and removes that club from the golf bag located in the golf cart, and then tees off; and (2) the golfer then drives the cart along the path to a location near the golf ball, guesses which one or two clubs might be proper, removes the clubs from the golf bag situated or attached to the golf cart; and then walks to the golf ball with the clubs in hand, and hits the ball. This second step continues until the golfer has placed the ball in the cup.
A problem occurs when a golfer selects the wrong club or clubs from the bag in the motorized cart. Improper selection can occur for example because of the lie or by mistaking the distance of the ball or the wind speed at the location of the ball. The golfer then must walk back to the cart and replace his clubs with a proper club. Since his ball may be a long distance from the golf cart, a long delay can result. Moreover, his partner in the motorized golf cart, which typically has two seats, could have driven the motorized cart to a new location, leading to even longer delays.
If two players are using a motorized cart on a golf course where motorized carts are permitted on the fairway, a similar problem may occur: the first golfer may choose one or two clubs, and the second golfer will drive the cart to a new position. If the first golfer has chosen the wrong clubs and must return to the golf cart at a new location to exchange clubs, the speed of play can be drastically reduced.
U.S. Pat. No. 5,727,642 discloses a non-traditional golf bag bay, namely a golf bag carrier assembly that can rotate. While the assembly is detachable, the assembly is not detached during play but rather is rotated out the way so that a disabled golfer can have a full swing motion while seated.
U.S. Pat. No. 4,533,013 discloses a non-traditional golf bag bay with plate like members detachable via lock pins to brackets.
Towing packages for golf carts are known, but are used for connecting golf carts to each other so that the carts can be pulled in a line, for example for easy movement.
SUMMARY OF THE INVENTION
In view of the above, the present applicant has developed a detachable golf club carrier, such as a pull cart, that can be outfitted to existing golf carts using an easily retrofitted hitch. This invention is the subject matter of U.S. patent application Ser. No. 09/924,039, entitled MOTORIZED GOLF CART WITH DETACHABLE GOLF CLUB CARRIER filed Aug. 7, 2001, which is hereby incorporated by reference herein.
While it is advantageous to use detachable golf club carriers on retrofitted existing golf carts, an object of the present invention is to provide a motorized golf cart for attachable golf club carriers which require less space than retrofitted golf carts. An additional or alternate object of the present invention is to provide a protected area for attached golf club carriers. Yet another or alternate object of the present invention is to provide a hitch easily fixed to a frame of a motorized golf cart.
The present invention provides a motorized golf cart for movement over a ground surface, the golf cart having a motor, a vertical golf bag bay; a hitching device in the vertical golf bag bay and a wheeled golf club carrier selectively attachable to the hitching device.
‘Vertical golf bag bay” as defined herein is a golf bag bay without a bottom, i.e. without a horizontal surface on which a golf bag bottom rests. Conventional golf carts now have a horizontal surface on which the bottom of the golf bag rests, and thus do not have vertical golf bag bays as defined herein. Vertical golf bag bays as defined herein thus may include, for example, an open rear end of the golf cart just behind the seats and also one with a U-shaped formed by two protective bumpers.
The wheeled golf club carrier preferably includes a hitching device removably connected to the first hitching device.
The wheeled golf club carrier thus can be easily attached and detached to the motorized golf cart, with the golf cart not requiring a traditional bag bay with a bottom on which a golf bag must rest. The golfer can hitch and unhitch the golf club carrier in the bottomless bag bay and wheel it, along with all the golfer's golf clubs, to a desired location on the course.
Preferably, two hitches are provided within the bag bay.
Also preferably, the bag bay has two protective extensions for aiding in protecting the clubs when attached with the carriers in the bag bay.
In a highly preferable embodiment, the wheels of the golf club carrier first are on the ground and then retracted from the ground surface as the second hitching device is connected to the first hitching device. With retraction, the golf clubs and the carrier thus are better protected on the cart as the cart moves, as ground disturbances are not transferred via the wheel of the golf club carrier as the golf cart is driven. Moreover, reverse motions of the cart will not cause the golf club carrier to jackknife or be damaged.
However, the wheel of the golf club carrier could remain on the ground in a less preferable embodiment. The golf club carrier then preferably includes at least one shock absorber.
The first hitching device may include a bar and the second hitching device a latch for latching onto the bar.
Preferably, the motorized golf cart preferably has two s
