A PICKUP AND PLACEMENT CYLINDER FOR STACKABLE GOLF TEE
MARKERS
This is a division of Canadian Patent Application Serial No. 2,452,443 filed
December
29, 2003.
The present invention relates to the field of golf tee markers and especially
to a
pickup and placement cylinder for stackable golf tee markers.
On tee boxes of golf courses, markers are used to indicate the tee off
positions for
golfers of different sex, age, ability etc. The markers are often moved so as
to
prevent excessive wearing of certain areas on the tee box and to provide a
particular
hole with a different length or degree of difficulty. The markers are also
temporality
removed by groundskeepers in order to maw or otherwise maintain the tee boxes.
As such, it is important to have markers which are easily picked-up and placed
into
the ground and effective means to accomplish the same and to store the markers
when not in use.
The following patents are considered to be of general relevance to the subject
matter
of the present invention and are not believed to anticipate or render the
present
invention obvious, whether taken alone or in any combination.
United States Patent No. 5,029,855 (Jamieson et al.) entitled GOLF TEE MARKER
AND RECEPTACLE discloses a marker for spiking into a tee box area having
indicated thereon the distance to the hole and the position of the hole on the
green
or other information. Two removable spikes are preferably used so that the
marker
is not inadvertently turned since such turning would result in the display of
false
information. The marker comprises a circular opening on its top surtace
leading into
a cavity in the form of an inverted cone for holding broken tees. The bottom
of the
cavity has a small opening to allow drainage of any liquid.

United States Design Patent No. D 346,634 (Evens) entitled COMBINED BROKEN
TEE RECEPTACLE AND TEE MARKER illustrates a flower-shaped tee box marker.
The marker is open at its top and has a single spike for placement into the
ground.
United States Design Patent No. D 311,431 (Vlleber) entitled COMBINED GOLF TEE
MARKER AND RECEPTACLE illustrates a half spherical marker having a single
spike.
Aspects of the present invention relate generally to stackable markers which
are
easily picked-up and placed into the ground.
According to an aspect of the invention described and claimed in parent
Canadian
Patent Application Serial No. 2,452,443, there is provided a golf tee marker
which
comprises a ground engaging portion; a body surmounting the ground engaging
portion and having in a top surface thereof a well for receiving therein a
ground
engaging portion of another marker for stacking markers; the well having a
drain hole
to avoid accumulation of liquid therein.
The well may be configured to facilitate entry and fitting of the ground
engaging
portion, such as a spike, for instance by having inwardly inclined side walls.
Disposed
beneath the body, within the body's perimeter and at a distance therefrom,
there may
be a flange parallel with the underside of the body. The flange may or may not
be
separated from the body. Since the flange is within the perimeter of the
underside
of the body, there is a rim around the underside of the body which provides a
surface
for lifting the marker out of the ground. The flange may assist with the
placement of
the marker. Beneath the body there may be disposed a protective member such as
a rubber washer to cushion impact and prevent dinect contact between the
bodies of
the markers upon stacking and thereby mitigate wear.
The spike well may be slightly deeper than the portion of a spike of another
marker
which may be inserted in the well, for instance, about 2mm deeper. The drain
hole
may advantageously run from the bottom of the well to the rim on the underside
of
CA 02466302 2004-05-21

the body. The exit of the drain hole is advantageously positioned such that,
when
markers are vertically stacked, liquid exiting the drain hole will not enter
into the
marker below. The ground engaging portion may be a spike which is threadingly
engaged into the underside of the body.
According to another aspect of the invention described and claimed in parent
Canadian Patent Application Serial No. 2,452,443, there is provided a golf tee
marker

flange
attached beneath the underside of the body and within the body's perimeter, to
assist
placement of the marker; a resilient washer disposed beneath the body for
inhibiting
direct contact between the bodies of stacked markers.
The marker may be a golf tee box marker or otherwise, such as markers for
delineating a temporary or permanent pathway or driveway, for instance on a
grass
field or other surface. The markers could be used for delineating lawn bowling
lanes.
The markers could have means of illumination or means of receiving iNuminating
means for improved visibility in low light, for instance for night golf. The
marker could
have slots therein to accommodate yellow warning tape or the like for enhanced
delineation.
According to an aspect of the present invention, there is provided a pick-up
and
placement cylinderfor stacking golf tee markers as described above which
comprises
an elongated cylindrical housing for housing markers therein and having an
opening

Turning now to Figure 4 where a pick-up and placement cylinder (13) is
illustrated
and Figures 5 and 6 which show top cutaway views of the cylinder. The cylinder
(13)
comprises a cylindrical casing (14) for stacking markers (1), a catch rod (15)
running
lengthwise within the walls of the casing (14). The rod (15) has top and
bottom
catches (16 and 17 respectively) attached thereto.
In operation, a user turns the turn lever (18), which causes the centre
turning gear
(19), which is connected to a shaft and bearing (20), to turn, thereby turning
the rod
turning gears (21), of which there are four in this embodiment, thereby
turning the
catches (16 and 17) and thereby allowing selective release and insertion of
the
markers as described below. The catches (16 and 17) are protected by a
removable
sleeve (22) and are vertically spaced about 6 cm from each other to
accommodate
markers of the size described herein. The vertical spacing could be different
based
on markers of different configurations.
The cylinder (13) may be made from a plurality of sections and assembled by
male/female connections with or without threading thus creating an overlapping
joint
(23). In this way, the small tolerances for the longitudinal holes in the
cylinder walls
will be more easily respected.
The gears (19 and 21 ) are mounted on a top plate (24) and are covered by a
cylinder
cap (25) A handle (26) is attached to the casing (14) for ease of use.
As seen in Figure 5, the rod turning gear is held in place by collar and
cotter key or
set screw arrangement (27) for easy removal, and screws (28) hold the cylinder
cap
(25) in place.
With reference to Figure fi, the operation of the cylinder is described. Three
of the
four sets of catch rods are shown, where "B" indicates the bottom catch rod,
and HT"
indicates the top catch rod. Although each set of catch rods will always be in
the
same position as the other sets of catch rods, in Figure 6, three different
positions
CA 02466302 2004-05-21
- $ -
(1,2 and 3) are shown for illustrative purposes. The top and bottom catches
are fixed
to the same catch rod but at different orientations.
In position 1, "B" is within the casing allowing a marker to enter and exit
the cylinder.
"T" juts out into the cylinder cavity to act as a stop for markers having
their undersides
below the level of the top catches.
In position 2, "T" is within the casing to allow a marker to drop down which
will be
caught by "B' which juts out in this position.
In position 3, "B" juts out so as to be positioned between the flange and
underside of
a marker and bears down upon the flange, pushing the marker into the ground.
Next
the catches are returned to position 1 which retracts "B", releasing the
marker.
In Figure 7, a transport and storage tube for stacking golf tee markers is
illustrated.
The tube (29) may be made of standard PVC (Polyvinylchloride) or other
suitable
material. The tube (29) has a handle (30) attached and is pivotable about a
set of
bolts with dome nuts (31) or other suitable means. The tube is open at the top
end
for receiving markers (1 ) therein and the handle (30) can be rotated out of
the way
of the opening. The bottom end of the tube has a rubber cushion (32) and
bottom
plug (33) with a hole for receiving the spike of a lowermost marker and is
held in
place by screws (34). The purpose of this tube is to hold the markers for easy
storage, transport, pick-up and distribution. Preferably, one tube holds
markers for
one golf hole, usually eight markers which simplifies the distribution of
markers. The
tubes may have the hole numbers indicated thereon or other indicia.
In Figures 8 and 9, a cabinet for storing the transport and storage tubes of
Figure 7
is illustrated. The cabinet has a base (35) and a lid (36) with a handle (37).
Inside
the base (35) are compartments (38) for receiving the transport and storage
tubes.
The lid (36) may be detached from the base. The cabinet may be mounted on
wheels and towed behind a vehicle or handled with a forklift, sling or the
like. The
cabinet may be made of plywood or other suitable material.

In Figures 10 to 12, a mowing tractor attachment for pick-up and placement of
markers is illustrated. The attachment is designed to pick up the markers and
hold
them while the tee box area is mowed and to then position the markers in the
desired
location. The mowing tractor attachment could be attached under the driver's
seat
or other appropriate location of a ride-on mower or other suitable vehicle.
The
attachment is hooked into the hydraulic system of the mower and directional
control
valves for it's hydraulic hydraulics are mounted, either on the dash of the
mower or
on the attachment itself. Mowers may require additional hydraulic capacity to
function
in this way.
Referring to Figure 10, a telescoping hydraulic cylinder (39), is attached at
a pivot
point (40) to the base of the vehicle attachment and holds the pick-up and
placement
cylinder (13) at the other end thereof. The hydraulic cylinder (39) is moved
vertical
by way of another telescoping hydraulic cylinder (41 ). In Figure 10, the
fully extended
and retracted positions (dotted lines) are shown. The hydraulics of the mower
(44)
are also shown in Figure 10 as well as the ground level (45). Hydraulic hoses
have
been omitted from the drawings for greater clarity.
As seen in Figure 11, the hydraulic cylinder (39), as seen in Figure 10, is
moved side
to side by yet another hydraulic cylinder (42). A centre {43) and two side
positions
(dotted lines) are shown. The vertical motion is illustrated by a dovNn
position (46)
and an up position (47). A cover (48) of the attachment is illustrated along
with the
base of the attachment (49) and the other pivot point and cylinder (50).
As seen in Figures 10 and 12, a square turn rod (51 ) is attached to the
hydraulic
cylinder (39), which when turned, moves the centre turning gear (19) from
Figure 5,
to any one of the three positions. As the hydraulic cylinder (39) is extended,
the turn
rod (51 ) slides through a rod guide and turner {52) which can be turned by
control
cables referred to as a flex turn cable (53) and catch rod turn lever (54)
seen in
Figure 10, mounted on the top of the tractor attachment.

In operation, an operator uses the hydraulic controls to manipulate the
position of the
maker carrying cylinder as required to pick-up up and place the markers.
The base of the attachment (49) is preferably made of standard 12 in. aluminum
or
other channel stock. The two large hydraulic cylinders (39 and 47) are
preferably
made of standard stock with a minimum of 44 in. stroke.
It can be seen from the illustrations and descriptions heretofore that the
device as
taught herein provides an advance in the art. The advantages realized by this
invention which have been discussed herein are in no way intended to provide
an
exhaustive list thereof and therefore other features and advantages may exist
and/or
be discovered by working of, or experimenting with, the present invention.
The foregoing are exemplary embodiments of the present invention and a person
skilled in the art would appreciate that modifications to these embodiments
may be
made without departing from the scope of the invention.
