DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] In FIG. 1, the ball retrieval attachment 12 for golf flagstick is shown mounted on a golf flagstick 10 and being used by a player P to remove a ball B from a golf cup C on a putting green G. The golf flagstick 10 includes a conventional flag F mounted proximate the top end of the golf flagstick 10, and the ball retrieval mechanism 12 mounted proximate the bottom end of the golf flagstick 10.

[0021] The details of the ball retrieval attachment 12 for golf flagstick are shown in FIGS. 2-4. As shown in FIG. 2, the ball retrieval attachment 12 includes a ball retrieval body 20 mounted on the flagstick 10 using a ball retrieval fastener/adjustment mechanism 24. The ball retrieval body 20 is a conical or concave annular disk that may be made of a fibrous material that supports the ball B, but allows for water to drain through the ball retrieval body 20. Alternatively, the ball retrieval body 20 may be made of a flexible, polymeric material. To assist in supporting the ball retrieval body 20, three or more reinforcement ribs 21 extending radially from the central hub of the body 20 may be provided. In addition, to further support the outer rim (perimeter) of the ball retrieval body 20, a memory spring wire 22 may be attached to the outer rim of the ball retrieval body 20. The soft, yielding nature of the fibrous material (or of the flexible, polymeric material) avoids damage to the green G should a player wish to remove the flagstick 10 from the cup C and place it on the green G. The ball retrieval fastener/adjustment mechanism includes ball retrieval attachment hub 24 that allows for height adjustable attachment and support of the ball retrieval body 20 on the flagstick 10. In a first embodiment, the ball retrieval attachment hub 24 may be attached using a common hose clamp with a screw-activated clamp mechanism to clamp the ball retrieval attachment hub 24 to the flagstick 10. If future adjustment is not needed, the ball retrieval attachment hub 24 may be adhesively attached to the flagstick 10. Such an embodiment provides for retrofitting the ball retrieval attachment 12 onto existing conventional flagsticks without the need to modify the flagstick. As is known with most flagsticks, the bottom of the golf flagstick 10 includes a flagstick ferrule 26 for insertion into a cup socket C.sub.S located in the cup bottom C.sub.B of the golf cup C to support the golf flagstick 10 in a vertical orientation (see FIG. 4).

[0022] As best seen in FIG. 4, in a second embodiment, the ball retrieval attachment hub 24 includes internal threads 42 defined in a central hub that engage external threads 40 that are formed on the flagstick ferrule 26 at the bottom of the flagstick 10. In this embodiment, the reinforcement ribs 21 provide additional strength and a raised surface that can be used to assist in threading the ball retrieval attachment 12 onto and off of the flagstick 10. A lock mechanism (which may be a set screw, similar to the set screw 74 shown in the embodiment of FIG. 7, or other fastener) may be used to lock internal threads 42 to the external threads 40 at a user-selectable height to further secure the ball retrieval body 20 to the flagstick 10. In a first position, the top of the ball retrieval attachment 12 is a distance D.sub.1 above the flagstick ferrule bottom 28. In a second position, the top of the ball retrieval attachment 12 is a distance D.sub.2 above the flagstick ferrule bottom 28. In this embodiment, an extender 50 (shown in FIG. 5) may be used to coarsely adjust the height (or distance) of the ball retrieval attachment 12 above the flagstick ferrule bottom 28. The lock mechanism may be used to provide finer adjustment of this distance. In the first embodiment, to adjust this position, the screw of the hose clamp is loosened and the ball retrieval attachment 12 is slid along the length of the flagstick 10 to its desired position. The screw of the hose clamp is then tightened to maintain the ball retrieval attachment 12 in its desired position relative to the flagstick ferrule bottom 28. In most embodiments of the ball retrieval fastener/adjustment mechanism 24, the mechanism 24 allows the ball retrieval body 20 to be removed from the golf flagstick 10 temporarily, to comply with tournament and/or PGA rules, if necessary.

[0023] The details of the extender 50 are shown in FIG. 5. The extender 50 includes an axial bore 54, through which the flagstick 10 extends. The lower end 52 of the bore 54 includes internal threads 56, that engage the external threads 40 (FIG. 4) on the flagstick ferrule 26. The upper end 58 of the extender 50 includes external threads 59 that are engaged by the ball retrieval attachment's internal threads 42. By providing extenders of different lengths, the height of the ball retrieval attachment 12 above the flagstick ferrule bottom 28 can be adjusted. In this embodiment, the flagstick 10 is modified to include the external threads 40 as an integral part of the flagstick ferrule 26, or the external threads 40 may be adhesively or otherwise attached to an existing flagstick ferrule 26.

[0024] In FIGS. 6-8, a third embodiment of the ball retrieval attachment 62 for golf flagstick is shown mounted on golf flagstick 60. In this embodiment, the ball retrieval attachment 62 is an integral unit (ball retrieval body) including a ball retrieval attachment hub 65 with internal threads 72, a frustoconical ball engagement surface or flange 68 and a cylindrical stem or riser portion or tube 67 having a lower end 75 attached to the ball retrieval attachment hub 65 and an upper end 76 attached to the ball engagement flange 68. The ball retrieval attachment hub 65 extends radially inward substantially perpendicular to the lower end 75 of the cylindrical riser portion 67. The ball retrieval attachment hub 65 includes a lower cylindrical extension 84 extending below the lower end 75 of the cylindrical riser portion 67, the lower cylindrical extension 84 having a set screw 74 that extends through a threaded bore 73 in the sidewall of the lower cylindrical extension 84 to lock the internal threads 72 of the ball retrieval attachment hub 65 to the external threads 71 on the flagstick ferrule 64 at a user-selectable height. The set screw 74 thereby provides a fine control of the height of the ball retrieval attachment 62 above the bottom 78 of the flagstick ferrule 64. The height of the riser portion 67 provides coarse adjustment of the height or distance D.sub.3 of the outer edge 77 of the ball engagement flange 68 above the bottom 78 of the flagstick ferrule 64. This height must be selected at the time of manufacture and the ball retrieval attachment 62 may be provided by a manufacturer in a variety of heights, such that a consumer could select the appropriate height for their application. The frustoconical ball engagement flange 68 extends upward and outward from the upper end 76 of the cylindrical riser portion 67 at a slight angle to the horizontal, the ball-engaging surface of the flange 68 sloping inward to thereby urge the ball B against the flagstick 60 and away from the side of the cup C. A number of openings 66 extend through the ball retrieval attachment hub 65, the cylindrical riser portion 67 and the frustoconical ball engagement flange 68 to provide drainage of any water in the cup. The openings can be circular, polygonal, or may form alphanumeric shapes, such as a brand name or other marketing language.

[0025] In both the second and third embodiments, the external threads 40, 71 may be formed integrally on the flagstick ferrule at the bottom of a flagstick. Alternatively, the ball retrieval attachment 62 may include a flagstick ferrule 64 as shown in FIGS. 6-8. The flagstick ferrule 64 includes a lower frustoconical portion 70 that is slightly tapered and a top surface 69. The lower frustoconical portion 70 is tapered for insertion into the similarly tapered cup socket CS located in the cup bottom CB of the golf cup C to thereby support the golf flagstick 10, 60 in a vertical orientation. As shown in FIG. 8, the ferrule 64 includes an attachment boss at its upper end of wider diameter than the lower frustoconical portion, the attachment boss having external threads 71 that mate with the internal threads 72 of the ball retrieval attachment hub 65 and are integral with and above the lower frustoconical portion 70. An unthreaded annular cap portion 82 is mounted on top of the attachment boss. A longitudinal, cylindrical bore 80 extends through the lower frustoconical portion 70, attachment boss, and the unthreaded cap portion 82 for mounting the flagstick ferrule 64 on a flagstick 60. The unthreaded cap portion 82 limits the extent to which the ball retrieval attachment hub 65 can be screwed onto the flagstick ferrule 64, thereby providing an accurate placement of the ball engagement flange 68 above the bottom 78 of the flagstick ferrule 64. Alternatively, bore 80 may be a blind bore and the bottom of the flagstick 60 may contact the bottom of the blind bore. The flagstick ferrule 64 can be attached to an existing flagstick using an adhesive or other attaching mechanism to retrofit the ball retrieval attachment on the flagstick 60.
