Golf ball retrieval system

Abstract

A golf cup insert has a funnel shaped body including a wall. The wall defines a first aperture having a diameter D1 and a second aperture having a diameter D2. The diameter D1 is sized to fit within a regulation size golf hole; the diameter D2 is smaller than the diameter D1. The insert can be used in a golf ball retrieval system to lift a golf ball out of a golf hole to assist the user and to prevent damage to the hole; the system also eliminates the need for any outside ball retrieval device.

DETAILED DESCRIPTION

(10) As shown in FIG. 1-3, a golf cup insert 100 is designed to fit in a golf hole 20. A golf hole 20 is by regulation 4.25 inches in diameter and at least 4 inches deep. The insert 100 has a tapered funnel shape including a first aperture 2, having a diameter D1, a second aperture 4 having a diameter D2 and a wall 6 extending between the first aperture 2 and the second aperture 4 at an angle relative a longitudinal axis A. The angle is between about 20 degrees and about 65 degrees, preferably in the range of between about 35 degrees and about 55 degrees. In some embodiments, at least a portion of the wall 6 extends at the angle relative a longitudinal axis A. The ratio of the diameter D2 to D1 can be in the range of between about 10% and about 60%, more preferably in the range of between about 15% and about 35%. It is also contemplated that in some embodiments a first portion of the wall 6 extends at the angle relative to the longitudinal axis A and a second portion of the wall 6 extends at a different angle relative a longitudinal axis A.

(11) As shown in FIG. 9, the insert 300 can be configured to include a first aperture 302, having a diameter D3, a second aperture 304 having a diameter D4 and a wall 306 extending between the first aperture 302 and the second aperture 304. The wall 306 can be configured to include a first portion 306a extending at the angle relative to the longitudinal axis A and a second curved portion 306b. The insert can include a plurality of radial slots 308. The angle is between about 20 degrees and about 65 degrees, preferably in the range of between about 35 degrees and about 55 degrees. The ratio of the diameter D4 to D3 can be in the range of between about 10% and about 60%, more preferably in the range of between about 15% and about 35%. It is also contemplated that in some embodiments a first portion of the wall 306 extends at the angle relative to the longitudinal axis A and at least a second portion of the wall 306 extends at a different angle relative a longitudinal axis A.

(12) The insert 100, 300 is designed to fit in a regulation golf hole such that it is easily installed and removed and it does not interfere with or in any way impede the path of the golf ball. The insert 100, 300 is designed such that the shape allows for easy capture of one or more golf balls when the insert is installed in a golf hole, while the insert 100, 300 is able to retain one or more golf balls when the insert is lifted and removed from the golf hole as discussed herein. In some alternate embodiments, the insert 100, 300 is designed allow a ball to be released onto the green upon lifting of the flagstick rather than being retained.

(13) In this embodiment, the insert 100 includes a plurality of slots 8 extending outwardly from the second aperture 4. As shown in FIG. 1-3, the plurality of slots includes a symmetrical star shaped pattern radiating from the second aperture 4. The plurality of slots can include four slots 8a having a length L1 and four slots having a length L2. The length L2 of the slots 8b is less than or equal to the length L1 of the slots 8a. In some embodiments, the length of L2 is between about 40% and about 60% of the length of L1. It should be considered that in some embodiments the insert can be made in one or more pieces, for example, in a two-piece snap together arrangement. The plurality of slots may not be necessary in some embodiments, as long as the insert is flexible enough to be fitted on the flagstick and sturdy enough to remain in place during play.

(14) The insert 100 is preferably made from a polymeric material such as a thermoplastic. The insert 100 can be molded for example, by injection or compression molding. Other materials such as metallic materials, ceramics or elastomers can also be utilized.

(15) Referring to FIGS. 4-8, a golf ball retrieval system 200 including the golf cup insert 100 (or 300 hereinafter) is shown. The system includes a flagstick 10. The flagstick 10 includes a first cylindrical portion 12 having a first end 14 for securing a flag 16 and a second end 18 for engaging a golf cup or hole 20.

(16) The flagstick 10, includes a retaining portion 22 proximate to the second end 18. The retaining portion 22, includes a first end 24 having a flange 26 and a second end 28 having a second cylindrical portion 30 sized to fit an aperture (not shown) in a golf cup or hole 20 to retain the flagstick 10 and allow for easy removal and replacement of the flagstick during play. The flange 26 has a diameter D5. The diameter D2 of the second aperture 4 is slightly larger than the diameter D5 thereby allowing the insert, which is flexible in the area of the plurality of slots 8 to be easily fit onto or be removed from the flagstick 10. In the installed position (e.g. FIGS. 4-5) the insert 100 rests on the flange 26, thereby forming a funnel shaped cup which can retain one or more golf balls 28.

(17) As shown in FIG. 6, the system 200 can be placed in a prone position, for example, while putting, the flagstick 10 is often placed on the sensitive green. Advantageously, when the system 200 is prone, the insert 100 is free to float from the installed (in a hole) position (as shown in FIGS. 4-5) to the uninstalled prone position. The shape and elements of the insert 100 allow the insert 100 to move so that the wall 6 is essentially parallel to the ground or green thereby avoiding damage to the area where the system is temporarily placed during play.

(18) Referring to FIGS. 7-8, the system 200 is shown as being removed from a golf hole 20. The flagstick 10 is typically pulled upward in the direction of arrow U, so that the retaining portion 30 disengages from an aperture (not shown) at the bottom of the hole 20. Initially, the golf ball 28 is retained in the insert 100. Because the shape of the insert, the weight of the golf ball 28 causes the insert 100 to tilt slightly, thereby retaining the golf ball 28. The golf ball 28 may now be recovered by hand thereby eliminating potential damage to the edge of the cup or hole that may have been caused by traditional manual retrieval.
