Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C. 119 (e)
of U.S. Provisional Application No. 60/853,951, filed on Oct. 24,
2006, which is hereby incorporated by reference in its
entirety.
FIELD OF THE INVENTION
[0002] This invention relates to the field of golf green
maintenance, and more specifically to a hole plug.
BACKGROUND
[0003] The greens on a golf course are sometimes aerated to improve
the growth of grass on the green by providing oxygen to the roots
of grass and as a means for exposing weed killer and fertilizer to
the grass of the putting surface, and for providing proper water
drainage. Aerating is accomplished by using spiked rollers that
pull small dirt plugs out of the putting surface. After aerating a
green, sand is spread over the green to fill the aerated holes.
[0004] The spiked rollers can do unintentional damage to the golf
hole on the green. For example, the spiked roller can damage the
sides of the hole. Also, sand can get knocked into the hole during
the process. Thus, the worker has to straighten the sides of the
golf hole to regain integrity of hole and has to remove all of the
debris and sand that has filled it. This is generally done
painstakingly by hand.

DETAILED DESCRIPTION
[0011] In the following detailed description, reference is made to
the accompanying drawings which form a part hereof, and in which is
shown by way of illustration specific embodiments in which the
invention may be practiced. These embodiments are described in
sufficient detail to enable those skilled in the art to practice
the invention, and it is to be understood that other embodiments
may be utilized and that structural changes may be made without
departing from the scope of the present invention. Therefore, the
following detailed description is not to be taken in a limiting
sense, and the scope of the present invention is defined by the
appended claims and their equivalents.
[0012] FIGS. 1 and 2 show a golf hole plug 100, in accordance with
one embodiment. FIG. 1 is a perspective view of golf plug 100 and
FIG. 2 is a top view of the golf hole plug. Hole plug 100 is a
cylindrically shaped unit having an outer wall 102. Hole plug 100
is dimensioned to fit within a golf hole and, in one embodiment,
has dimensions of about 4.25'' in diameter and about 6.75'' in
height. Thus, hole plug 100 fits snuggly within a regulation size
golf hole.
[0013] In one embodiment, hole plug 100 has dimensions of about
4.25 inches in diameter and about 5 inches in height for use in a
practice green, for example.
[0014] In one embodiment, hole plug 100 is made from a durable,
lightweight, weather resistant foam material. For example, hole
plug 100 can be made from a closed-cell, polyester foam having a
density of about 1.2 pounds per cubic foot. Some embodiments use a
foam having a density of between about 1.0 pound per cubic foot to
about 1.4 pounds per cubic foot. The foam material of the hole plug
is chosen to be strong enough to protect the integrity of the golf
hole by supporting the sides of the hole, while being soft enough
to not do any damage to a aerating spikes.
[0015] Hole plug 100 can include one or more holes 110 extending at
least partially into the plug to allow a user to grip the hole plug
100 and pull it out of a golf hole. In one example, holes 110 have
a diameter of about 0.75 inches. This allows a user to reach into
the hole plug with a thumb and forefinger to remove the plug from a
hole. In some examples, holes 110 extend all the way through the
plug 100. In other embodiments, holes 110 extend partially into the
plug 100. Holes 110 can be formed when plug 100 is being molded or
they can cut from the plug body after it is formed.
[0016] Hole plug 100 includes an upper surface 104 which prevents
sand from falling into a golf hole when hole plug 100 is mounted
therein. The hole plug 100 can be used in either direction and so
when one side has become damaged the hole plug can be reversed.
[0017] FIG. 3 shows hole plug 100 mounted within a golf hole 120 on
a green 200, and FIG. 4 shows a side, cross-section view of hole
plug 100 within the golf hole. To use the hole plug 100, the golf
cup is removed from the golf hole 120 and the hole plug 100 is
placed within the golf hole 120. Outer wall 102 of golf plug 120
abuts against inner dirt wall 402 of golf hole 120. Thus, hole plug
100 protects the integrity of the golf hole when aerating greens by
preventing the tines from damaging walls 402. Moreover, the
material of hole plug 100 allows aeration tines to penetrate plug
100 without pulling it out of the hole. After aeration, grass and
dirt plugs are removed from the greens surface using a plow or a
plug pusher.
[0018] Plug 100 can also be used when topdressing green 200 to keep
sand from filling up golf hole 120. As the sand is spread on the
green 200, top surface 104 of the hole plug 100 prevents sand from
falling into hole 120. After sanding, hole plug 100 is removed and
the golf cup reinserted into golf hole 120. Hole plug 100 can be
left in holes during winter months also. In some embodiments, the
hole plug 100 can be reused many times.
[0019] FIGS. 5 and 6 show a hole plug 500, in accordance with one
embodiment. FIG. 5 is a cross-section view and FIG. 6 is a
perspective view of hole plug 500. In this example, hole plug 500
includes the same general cylindrical dimensions as hole plug 100
but includes an H-shaped cross-section. Outer walls 502 protect the
integrity of the hole while aerating, while central wall surface
504 collects sand to keep sand from filling up the hole during
topdressing.
[0020] In other embodiments of the hole plugs described above,
other techniques can be used to get the hole plug out of the hole.
For instance, a washer can be attached to the bottom of the hole
plug using a string or rope extending though the plug. The string
is then pulled to get the plug out of the hole. In one example, a
cork-screw type device can be screwed into the top of the hole plug
and the plug is then pulled out.
[0021] Hole plugs 100, 500 can also be used in other situations
where a hole needs to be plugged during aeration, for example in a
cemetery.
[0022] It is understood that the above description is intended to
be illustrative, and not restrictive. Many other embodiments will
be apparent to those of skill in the art upon reviewing the above
description. The scope of the invention should, therefore, be
determined with reference to the appended claims, along with the
full scope of equivalents to which such claims are entitled.
