Description

FIELD OF THE INVENTION The present invention relates to a system comprising flagpole and ferrule for use in marking a golf hole, wherein the flagpole comprises a first end attached to a ferrule and another end intended to be a freely visible end with a flag, and wherein the ferrule comprises a main part attached to the flagpole and a bottom part intended for placement in a hollow cup with ferrule base, the main part of the ferrule comprising a top surface with a flagpole hole for receiving a flagpole in which the flagpole and ferrule are secured by fastening means.

The present invention further relates to a ferrule for use in such a system.

Background of the Invention It is well known that the location of a golf hole (or simply referred to as a hole) is marked with a flagpole (or simply referred to as a rod) having a pennant or flag at the free end and the rod being located in the center of the hole. by means of a hollow cup located in the hole and below the level of the surrounding putting green.

It is also known that the part of the rod which is placed in a hole comprises a ferrule which fits in a ferrule base of a hollow cup.

With the golf rule that the rod must be in the cup during play, time is saved on the course.

The risk, however, is that the greenkeepers will be forced to do some more work.

The edge of the hole can be easily destroyed when the ball has to go up the hole when the flag is in.

For example, if the flag is not raised before the ball is picked up, there is not enough space for both the flagpole, the golfer's hand and the ball.

One of the disadvantages of the prior art is that, firstly, the ball is not easier to get out of the hole and, secondly, is not easy to get out of the hole without damaging the hole edges and / or the grass.

DK 180354 B1 2 US 6939239 B1 describes a system for marking a golf hole, comprising a flagpole with mounted ferrule, a hollow cup with a central hole arranged in the lower part, and a disc-shaped element attached to the flagpole by means of a screw. The ferrule has a design that corresponds to the design of the hole in the hollow cup. The disc-shaped element is located at a first distance from the top of the ferrule and at the same time at a second distance from the upper edge of the hollow cup. The element has an outside diameter that is smaller than the inside diameter of the hollow cup that allows the flagpole to sway in the wind without hitting the edge of the golf hole.

A disadvantage of this system is that over time the disc-shaped element will lose clamping force against the flagpole due to wear. Furthermore, it is necessary to remove the ferrule before the disc-shaped element can be mounted, if the element is not manufactured in several parts. To prevent the flagpole from hitting the edge of the hole, it is necessary to make the element of a relatively rigid material.

Object of the invention It is thus the object of the invention to provide a system which is an improvement of the prior art, wherein the ferrule has a roundel which forms a cone / bowl so that the ball is able to rest on a rondel placed in the groove of the ferrule, and where the ball is able to lie up against the rod when the ball enters the hollow cup, where the rod and ferrule are located. It is also an object of the invention to provide a pad which is elastic and thus flexible and resilient so as not to cause damage to the green or hollow edges.

It is also the object of the invention to save time when the ball is going up the hole. Description of the invention According to a first aspect of the invention, the above object is achieved with a system comprising flagpole and ferrule for use in marking a golf hole as initially described and as described in the preamble of claim 1, wherein the main part of the ferrule further comprises a mounting means where the replaceable elastic pad is arranged on the mounting means.

DK 180354 B1 3 The mounting means is located on the outside of the ferrule and may be a projecting flange with one or more pins for holding the disc or it may be a groove which, for example, is molded or turned into the outer surface of the ferrule. Alternatively, there are no mounting means at all, as the disc can be molded in such a way that the inside hole diameter of the disc is smaller than the outside diameter of the ferrule, and so that the disc must be tilted on the ferrule and thus alone with its own clamping force be able to maintain its position without mounting means on the ferrule. By fasteners is meant indirect or direct fasteners. Examples of indirect fasteners are glue or silicone that holds the rod and ferrule. Examples of direct fasteners are threads, snap couplings and bayonet couplings. By elastic is meant here, for example, rubber or another elastic polymer, where the pad is made of such a material, and thus essentially returns to its original shape when it is no longer exposed to external forces. If the system is laid down on the green, for example, the roundabout is exposed to the weight of the system and the roundabout yields so that no holes or marks are left in the green. When the pad is no longer loaded - when the system is lifted up and placed in the golf hole again - for example - the pad returns to its previous shape.

This makes it possible to manufacture, sell and supply a system for mounting in existing hollow cups prepared for this system. In a preferred embodiment, the rod will be made of fiberglass, as this makes it possible to produce flagpoles which, due to price, weight and workability, are attractive. Alternatives can be, for example, other composites. In another aspect, the present invention also relates to a system in which the mounting means is a circular groove, wherein the circular groove is inclined 5 to 85 degrees relative to the perpendicular to the ferrule, however preferably 10 to 30 and further preferably 20 degrees and thus forms an acute angle. towards the top surface and an obtuse angle towards the bottom part of the ferrule. This makes it possible to optimize the inclination of the disc so that the ball remains on the disc when the system is lifted out of the cup. This adds to the roundabout the necessary

DK 180354 B1 4 ge rigidity so that it is able to lift the weight of the ball.

The groove in the ferrule and the cone-shaped roundel also ensure that the rules from R&A and USGA are complied with.

R&A (The Royal and Ancient Golf Club of St Andrews is one of the oldest golf clubs in the world, and is the governing body for golf over large parts of the world) and the USGA (United States Golf Association which is the national governing body for golf in the USA, its territories and Mexico) describes that there must be a minimum of 4 ”from top grass edge to bottom.

By bottom is meant where the ball rests in the hole with or without flagpole.

In addition, the upper edge of the hollow cup must be located at least 1 ”from the upper grass edge.

The roundel groove is designed so that the roundel forms a cone / bowl, and so that the ball lies up against the rod when the ball enters a golf hole where the system is already inserted.

This also makes it possible to replace a ferrule's disc if the disc is broken or if the disc needs to have a different look, color or advertisement printed on it.

The elastic and flexible rubber pad, which in a preferred embodiment is made of 5 mm EPDM rubber, can be bent so that it does not damage green or hollow edges.

In another aspect, the present invention also relates to a system in which the bottom part of the ferrule comprises at least two outer circular grooves for receiving an elastic material.

This makes it possible to guide, insert and hold the ferrule in the ferrule base of a golf cup, where the elastic material in a preferred embodiment is O-rings of an elastic and flexible material such as rubber.

In a further aspect, the present invention also relates to a system in which the flagpole has an extension of 2 - 3 meters, however preferably 24 meters in the direction of propagation of the flagpole between the first end of the flagpole and the second end of the flagpole.

This makes it possible to see the rod from a very long distance and it also makes it easy to grab the rod, where there is a certain balance and where the rod can be lifted up from the hole at the same time as the ball.

The present invention also relates in a still further aspect to a system, the system further comprising a hollow cup with a ferrule base, the hollow cup being calculated for the inner dimensions of a golf hole as well as the outer dimensions of the ferrule. 5 This makes it possible to manufacture, sell and supply a complete unit, where the rod, ferrule and cup fit together, and where the unit is thus ready for use.

Golf holes have a standard dimension. The adaptation of the hollow cup to the golf hole will thus also be standardized. Rod and cup, on the other hand, can be manufactured in different ways, which is why it is important that these elements in the system fit together so that they are ready for use.

In a further aspect, the present invention also relates to a ferrule for use in a system such as the above.
