Golf cup

Abstract

A golf cup assembly is disclosed. The golf cup has a lower cylinder assembly having a cylindrical housing and a transverse member positioned within the interior of the cylindrical housing. A generally cylindrical sleeve depends from and is supported by the transverse member and is adapted to receive and support a flagpole. An upper cylinder has a sidewall adapted to slidably engage the upper portion of the lower cylinder assembly and extends above the upper rim of the lower cylinder housing. The overall assembly has a means for securing the upper cylinder to the lower cylinder assembly. Preferably, the upper cylinder is plastic and the lower cylinder assembly is metal.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the golf cup, which is the device that sits within the golf hole. The device serves a number of duties: 1) the golf cup supports the flag pole vertically within the center of the hole to clearly identify the location of the hole to golfers who are a substantial distance from the hole; 2) the golf cup prevents the soil which forms the golf hole from collapsing inwardly; 3) the golf cup is often colored white to make the hole more visible and thus make putting more convenient for golfers who are near the hole; and 4) the golf cup serves as a resting place for balls that are successfully putted into the hole and is often recognized for the tone that it produces when the ball drops into it.

2. Discussion of the Prior Art

Ordinary golf cups contain three common features: 1) an outer cylinder (approximately four and a quarter inches in diameter) that provides visibility to the golfer and prevents the soil surrounding the hole from collapsing inwardly; 2) a flagpole support cylinder that sits coaxially within the lower half of the outer cylinder and provides a snug fit with the flag pole to keep the flagpole vertical; and 3) a tapered bottom feature that sits within the mid-portion of the outer cylinder and connects the outer cylinder to the flagpole support cylinder. The tapered bottom feature supports the golf ball once putted into the hole and guides the pole into the flagpole support cylinder.

The flagpole support cylinder and the bottom piece of the flagpole (commonly referred to as the “ferrule”) are exposed to a great deal of “wear and tear”. There is a great deal of dirt and sand in the environment in which they exist and the wind on the flag and repeated flagpole removal and replacement create a powerful abrasive force between the two devices. Therefore, golf cups that are constructed out of metal are commonly considered to last much longer due to their greater resistance against this abrasive force.

However, metals are not naturally white and thus must be painted in order to sustain visibility. A chipped, rusty, or mis-colored cup can create a negative impression of a golf course and its greens keeper. For this reason, some greens keepers prefer to use white plastic cups due to their lower cost and natural white finish, which cannot be “chipped” away from the outer cylinder by the flagpole. While plastic cups are less expensive and easier to maintain, metal cups are more traditional, last longer, and produce the cherished “ball-drop” tone that many golfers and greens keepers demand. For these reasons, many greens keepers are forced to switch back and forth between cup styles, depending on what their golfers currently favor. As is the case with both common metal and plastic cups, when a feature becomes worn or defaced, the entire cup must be refinished or discarded.

Typically, there are two sizes of golf cups that a greens keeper must procure and use. One is for practice putting greens and the other is for greens used in regular play. The golf cup used on regular greens is generally several inches deeper that the golf cup used on practice putting greens. The deeper cup is necessary on regular greens, because the golf cup must support the flag and flagpole. In order to provide the required stability to support the flagpole, the golf cup used on regular greens must have a greater exterior surface area than the golf cup used on practice greens.

DETAILED DESCRIPTION OF THE INVENTION

In describing a preferred embodiment of the invention illustrated in the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.

With reference to the drawings, in general, and FIGS. 1 through 15 in particular, the golf cup apparatus of the present invention is disclosed.

In FIG. 1 , there are illustrated three drainage openings 10 , flagpole support cylinder's top opening 12 , tapered bottom feature 7 of a generally transverse member positioned within the interior the lower cylinder 5 . FIG. 2 again shows the three drainage openings 10 and the flagpole support cylinder's bottom opening 13 and the flagpole support cylinder 9 depending from the transverse member. Also shown here are the support beams 15 which serve to add stability to the lower cylinder 5 as well as the bottom side of the tapered bottom feature 7 . Collectively, the tapered bottom feature 7 and support beams 15 constitute the transverse member. FIG. 2 also displays the snap gaps 17 which are defined in the lower cylinder 5 . The snap gaps 17 allow the snaps 16 (shown in FIG. 8 ) room to fit into the lower cylinder 5 . FIG. 3 shows a sectional view of the lower cylinder 5 with the tapered bottom feature 7 and the flagpole support cylinder 9 . This view makes evident the upper cylinder seat 21 which is defined in the upper portion of the lower cylinder 5 . FIG. 4 again shows the upper cylinder seat 21 and a sectional view of a support beam 15 .

FIG. 5 shows a top plan view of the upper cylinder 2 and the snaps 16 which are located 120 degrees apart from one another. FIG. 9 shows an exploded assembly view of the upper cylinder 2 having a snap 16 aligned with a snap gap 17 and the upper cylinder 2 aligned with the upper cylinder seat 21 . FIG. 10 shows the upper cylinder 2 connected to the lower cylinder 5 by means of a snap 16 engaged with a snap gap 17 with the upper cylinder 2 engaged with the upper cylinder seat 21 .

FIG. 11 shows the first step of an alternate fastening method using a twist-locking technique with a slot 22 in the upper cylinder 2 and a knob 23 on the lower cylinder 5 . Also displayed is a snap 24 in the horizontal portion of the slot 22 . In FIG. 12 , the knob 23 is engaged with the vertical portion of the slot 22 . FIG. 13 shows the snap 24 securing the knob 23 in the slot 22 by means of a twisting action 25 .

FIGS. 14 and 15 illustrate an alternative embodiment of the golf cup according to the present invention. In this embodiment, upper cylinder 2 is seated along the upper portion of the interior sidewall of lower cylinder 5 . Preferably, upper cylinder seat 31 extends into lower cylinder 5 to the top of tapered bottom feature 7 thereby forming a substantial portion or substantially all of the visible interior sidewall of the golf cup. Inwardly protruding knobs 23 are slidably engaged within slots 22 to secure the upper plastic cylinder 2 to lower cylinder 5 . Flagpole support cylinder 9 has longitudinal drainage grooves 33 along the interior of the cylinder sleeve to facilitate drainage of water from within the golf cup. Drainage grooves 33 permit water that would ordinarily accumulated near the bottom of the flagpole. This drainage feature helps prevent rotting of a wooden ferrule.

Lower cylinder 5 is preferably sized so that it can be used separately as a practice putting green golf cup or, in conjunction with upper cylinder 2 , as regular green golf cup. Existing practice putting green golf cups can be fitted with a plastic upper cylinder 2 to provide the golf cup assembly according to the present invention. In this embodiment, the upper cylinder 2 may be secured to lower cylinder 5 by, for example, a friction fit, a clip or the like. The lower portion of upper cylinder 2 is preferably seated within the interior wall of the upper portion of the practice putting green cup.
