0 "MAGNETIC GOLF BALL COLLECTING DEVICE" Field of the Invention cThe present invention relates to a device for collecting golf balls and relates particularly to a magnetic golf ball collecting device that permits a golfer to easily pick up a golf ball without having to bend over or straining their knees and back.

Background to the Invention 0 0 Golf is already a very popular recreational sport for many people, and its popularity will continue to increase as the number of retirees in wealthy countries increases. However, for many golfers having to repeatedly bend down to pick up the ball after a putt, or to retrieve a ball when the ball has landed in shrubs, bushes, sand or water, can become a major ordeal as it places considerable strain on their knees and back. This is especially a problem with the elderly, people with arthritis, those with back injuries, those who have had joint replacements (hip or knee) and those with some other sort of restriction in movement.

Prior art devices exist which consist of a pliable plastic tube having an inside diameter slightly less than the diameter of a golf ball, which when pressed down hard on a golf ball grips the ball. Other devices comprise a soft rubber suction cup which functions in a similar manner. Such prior art devices can be attached to the end of a shaft, for example, to the grip of a golf club, so that the device can be used to collect a ball from ground level without bending down. Although such devices generally function in an acceptable manner, they tend to be somewhat bulky and can be difficult to attach to and/or remove from the grip of the golf club. Because the attachment of the device relies on friction or a screw-thread connection, considerable force may be required to attach or remove the device.

The present invention was developed with a view to providing a golf ball collecting device that can be easily attached to and removed from the end of a shaft, such as the grip of a golf club, without the application of undue force.

3 References to prior art in this specification are provided for illustrative purposes only and are not to be taken as an admission that such prior art is part of the common general knowledge in Australia or elsewhere.

Figure 7 is a side view of the accessory illustrated in Figure 6; Figure 8 illustrates the golf ball collecting device of Figure 1 together with a golf ball marker attached to a grip of a golf club; and, Figure 9 shows how the golf ball collecting device of Figure 1 together with the golf ball marker can be easily removed from the grip of the golf club.

Detailed Description of Preferred Embodiments A preferred embodiment of the golf ball collecting device 10 according to the invention, as illustrated in Figures 1 and 2 of the drawings, comprises a cup 12 adapted to successfully hold a golf ball (not shown) therein. The cup 12 incorporates some magnetic material to enable the device to be attached by magnetic force to the end of an elongate object, such as a golf club. Hence in this manner the golf club with the device attached thereto can be used to retrieve a golf ball from ground level without having to bend down. The golf ball can be gripped by the device 10 by aiming the cup 12 at the golf ball and pressing on it slightly, thus allowing the golfer to easily retrieve the ball without having to bend over or kneel and risk straining their knees or back.

The device 10 can be quickly and easily attached to the golf club, and just as quickly and easily removed after the golf ball has been retrieved.

In the preferred embodiment of the device 10 the magnetic material comprises a first metal disc 14 which is attached to a rear face of the cup 12.

Preferably the elongate object is a golf club 16, as illustrated in Figures 3 and 4, and the handle 18 of the golf club is provided with some magnetic material in connection therewith. In the illustrated embodiment the magnetic material provided in connection with the handle 18 comprises a second metal disc which is attached to the top end of the handle grip 18. Preferably the first and second metal discs 14 and 20 are both magnets, which are attached to the cup 12 and the handle grip 18 respectively with opposite poles facing outwards, so that when the first and second metal discs are brought into close proximity they attract each other and the device 10 is held on the grip 18 by magnetic attraction. No external force need be applied to attach the device to the golf club grip 18, because of the magnetic attraction when the two metal discs are brought into close range. Likewise, very little force is required to break the magnetic attraction and remove the device 10 from the grip 18.

However the magnetic force between the two metal discs is sufficiently strong that it will readily hold both the device 10 and the weight of a golf ball 22 securely on the end of the handle grip 18.

The cup can be made from any suitable material such as rubber, plastic, steel/aluminium, Teflon, wood with a rubber ring or lining, or any other material that would hold onto a golf ball successfully. In the illustrated embodiment the cup 12 comprises a substantially hemispherical concave surface 24 having an inner diameter similar in size to that the outer diameter of golf ball 22. The cup 12 further comprises an annular protrusion 26 extending inwards around the circumference of the cup 12 and which is adapted to grip the outer surface of the golf ball 22. The cup 12 is made from a suitable resilient material, such as rubber, and is shaped to hold a golf ball therein by friction between the annular protrusion 26 and the surface of the golf ball 22. In an alternative embodiment, the cup is made from a rigid material, such as steel, and only the annular protrusion 26 is made from a suitable resilient material such as rubber, so that the golf ball is held in the cup by friction between the annular protrusion 26 and the surface of the golf ball.

Advantageously, the golf club collecting device further comprises a golf ball marker, also made from magnetic material, for marking the location of a golf ball on a putting green when the ball is removed to permit other players to putt. In the preferred embodiment, as illustrated in Figures 5, 8 and 9, the golf ball marker comprises a third metal disc 30 which can also be attached to the handle 18 of the golf club by magnetic attraction. The golf ball marker 30 can be placed on the green or picked up from the green without bending down using the golf club 16. Preferably the third metal disc 30 is also a magnet 8 which can be held on the handle grip 18 between the first and second discs 14 and Preferably the golf club collecting device further comprises an accessory comprising a clip 40 adapted to slide onto a belt or the edge of a bag (not shown) and having some magnetic material incorporated therein, wherein the cup 12 and/or the marker 30 can be attached to the accessory by magnetic force. In the embodiment illustrated in Figures 6 and 7, the clip 40 is made of a resilient material, such as spring steel or plastic, and comprises a substantially planar member 42 in a U-shaped configuration, having a gap 44 between facing surfaces of a size to accommodate the thickness of a belt or fabric snugly therein. One of the facing surfaces is provided with one or more protrusions 46 adapted to grip the belt or fabric between the facing surfaces.

In this embodiment the magnetic material incorporated in the clip comprises a fourth metal disc 48 which is affixed to an external face of the U-shaped planar member 42. The clip 40 can be worn by a golfer and used to carry the golf ball collecting device 10 and/or one or more golf ball markers 30 in a readily accessible manner.

Now that preferred embodiments of the golf ball collecting device have been described in detail, it will be apparent that it provides a number of advantages over the prior art, including the following: It is easy to use and requires no externally applied force to attach to the golf club, and relatively little force to remove from the golf club.

(ii) It is of simple and robust construction and readily lends itself to mass production.

(iii) It can be easily carried on a simple belt accessory, together with matching golf ball markers, in a readily accessible manner.

It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention. For example, it is not essential 9 that the cup of the device grip the golf ball by friction; it could be designed to hold the ball successfully by suction. Therefore, it will be appreciated that the scope of the invention is not limited to the specific embodiments described.
