Description

MAGNETICALLY ATTACHED GOLF TEE

TECHNICAL FIELD

The invention generally pertains to golf tees, and more particularly to a golf tee having an upper golf ball holding section that is magnetically attached to a lower section that is inserted into the ground.

BACKGROUND ART

One of the most popular sports throughout the world is golf. Unlike many other sports, golf does not require extreme physical exertion. Therefore, golf can be played by various types of people including men, women, children and adults.

A typical golfer will possess a set of golf clubs and a few golf balls. When playing golf, a course consisting of series of holes is traversed. Each hole will be at a pre-determined distance from where a golfer will initially hit a golf ball. The distance from initial hit location to the hole is often significant, so it is common for a golfer to hit the ball multiple times on the way to the hole. These longer distance hits (as compared to shorter distance hits called putting) are referred to as driving. In order to most effectively hit a golf ball when driving a golfer will utilize a golf tee. A common style of golf tee is a wooden stake-type device that is inserted into the ground and supports a golf ball on its upper surface. A golf tee allows the golf ball to be elevated off the ground, usually above the grass-line, which creates a better impact angle for the golf club on the golf ball. Most golfers carry a number of golf tees with them when playing a round of golf. A number of tees is necessary since it is common for a tee to break as a result of the golf club impact. Also, golf tees often become dislodged from the impact and subsequently lost.

As a result of this problem, it would be beneficial and cost effective to provide golfers with a golf tee that could separate from an impact and then be re-assembled for further use. With a golf tee having this capability, a golfer would not have to carry a large number of tees and would not have to deal with the necessity and/or expense of constantly replacing golf tees.

DISCLOSURE OF THE INVENTION

The Magnetically Attached Golf Tee (MAGT) is designed to replace conventional golf tees that are often damaged when struck by a golf club. In its basic design, the MAGT consists of a lower section and an upper section that detaches when struck with a golf club.

The upper section has an upward flange and includes an upper concave surface and a lower flat surface. The lower flat surface has attached, by an attachment means, an upper permanent magnet having a downward facing north pole. The lower section has an upper surface, and a lower pointed end that is dimensioned to be inserted into the ground of a golf course or driving range (hereinafter golf course). To the upper surface is attached, by the magnet attachment means, a lower permanent magnet having an upward facing south pole. When the north pole of the upper permanent magnet interfaces with the south pole of the lower permanent magnet, the upper section is magnetically attached to the lower section. Thus, when the upper section is struck by a golf club, the upper section can separate from the lower section which remains inserted into the ground of the golf course. To reuse the MAGT the upper section is magnetically retrieved and re-attached to the lower section. The magnet attachment means is preferably comprised of an adhesive that is directly applied to the surfaces that are to be attached. Alternatively, the upper section as well as the lower section can include a cavity that is dimensioned to frictionally attach the respective permanent magnet. To further enhance the attachment means an adhesive can be applied to the cavities.

In view of the above disclosure the primary object of the invention is to produce a MAGT having an upper section that can separate from a lower section when the upper section is struck by a golf club. When the upper section is retrieved and re-attached to the lower section the MAGT can be reused.

In addition to the primary object of the invention it is also an object of the invention to produce an invention that:

• can be made of various materials,

• can be produced in a variety of lengths,

• offers zero resistance when struck by a golf club,

• is cost effective from both a manufacturer's and consumer's point of view.

These and other objects and advantages of the present invention will become apparent form the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.
