Claims
I claim:
1. An improved golf tee comprising, in combination, flexible
bendable hollow stem means and rigid nonbendable turf-inserting
means having one part thereof permanently fastened to said stem
means and another part thereof separable from said stem means and
insertable into the hollow of the latter for pushing upon said one
turf-inserting part to insert the latter together with said stem
means into turf, said one turf-inserting part fast on the bottom of
said stem means, said stem means and said one turf-inserting part
having coaxial aperture means therein opening to the top of said
stem means in which said other turf-inserting part may be received,
said other turf-inserting part having an elongated shank receivable
in said aperture means and engageable with said one turf-inserting
part, said other turf-inserting part having a head which, when said
shank is received in said aperture means, is disposed above said
stem means so that it can be pushed upon to transmit a pushing
force via said shank, to said one turf-inserting part.
2. An improved golf tee as claimed in claim 1, said other
turf-inserting part having a reduced diameter pointed lower end so
that said other turf-inserting part can be used as a ball marker on
a golf green during putting.
3. An improved golf tee as claimed in claim 1, said one
turf-inserting part conically pointed at the lower end thereof to
serve as a turf-inserting pilot for said stem means.
4. An improved golf tee as claimed in claim 1, said other
turf-inserting part having a conical shoulder formed thereon, said
one turf-inserting part also having a conical shoulder formed
thereon, the two shoulders engaged during insertion of said golf
tee into turf for transmitting said pushing force from said other
turf-inserting part to said one turf-inserting part.
Description
My invention relates to golfing.
The principal object of my invention is the provision of an
improved golf tee which has flexible hollow stem means so that it
doesn't break or cut down on golf driving yardage and
turf-inserting means so that the golf tee can be easily inserted
into any type of turf encountered in use.
The foregoing object of my invention and the advantages thereof
will become apparent during the course of the following
description, taken in conjunction with the accompanying drawings,
in which:
FIG. 1 is a vertical sectional view of a golf tee embodying my
invention;
FIGS. 2, 3 and 4, are, respectively, top and bottom plan and
transverse sectional views of said embodiment;
FIGS. 5 and 6 are, respectively, front elevational and top plan
views of said embodiment showing the same being inserted into
turf;
FIG. 7 is a front elevational view of said embodiment shown in use;
and
FIG. 8 is a front elevational view of a part of said embodiment
shown in use.
Referring to the drawings in greater detail, 10 generally
designates said embodiment which comprises flexible stem means 12
and turf-inserting means in two parts, one of which, designated 14,
is insertable into and removable from said flexible stem means 12,
the other of which, designated 16, is permanently anchored to said
flexible stem means 12. Said flexible stem means 12 may be made of
a tough polyurethane compounded rubber and is provided with a
central axial aperture 13. The flexible stem means 12 is provided
with a spherical surface 17 to support a golf ball and between the
surface 17 and the aperture 13 the material of the flexible stem
means 12 is removed to accommodate said golf ball and for economy
of material. The turf-inserting part 16 may be made of metal, such
as aluminum, and to enhance the bonding of the same with said stem
means 12 the part 16 is provided with a reduced diameter shank 15
which extends inwardly into the lower end of the aperture 13. The
shank 15 is provided with an aperture 19 which is coaxial with the
aperture 13 for receiving the turf-inserting part 14. The
turf-inserting part 14 is an elongated cylindrical object which may
be made of metal, such as aluminum, and is provided with an
enlarged head 20 at its upper end and a reduced diameter pointed
shank 21 at its lower end. A conical shoulder 22 is formed between
the main body portion of said turf-inserting part 14 and the shank
thereof. The turf-inserting part 16 serves as a turf-inserting
pilot for the flexible stem means 12 and for this purpose is
provided with a conically pointed lower end. The turf-inserting
parts 14 and 16 together serve as force transmitting means during
insertion of the golf tee 10 into turf and for this purpose the
aperture 19 in the shank 15 is formed with a conical shoulder 23 at
its upper end which engages the shoulder 22 for transmitting the
turf-inserting part 16 the inserting force applied to the head
20.
In use of my invention, said embodiment 10 is assembled with the
turf-inserting part 14 received in the apertures 13 and 19 and the
stem means 12 is gripped with the first two fingers and the
turf-inserting part 14 with the thumb of the user. The
turf-inserting part 16 is applied to the turf and pushed upon
indirectly by means of the turf-inserting part 14 which is pushed
upon directly by the user's thumb until the stem means 12 is sunk
into the turf an amount desired by the user. A golf ball, such as
the golf ball G, is then supported on the top of the stem means 12
via the spherical surface 17 thereof. The user is able to address
the golf ball G and drive it with a golf club in the usual manner.
The stem means 12 flexes (as show in dash-dot lines in FIG. 7)
during the driving of the golf ball G from impact with the club
head and because the stem means 12 is hollow it offers a minimum
resistance to the momentum of the club head to permit maximum
follow through thereof. The turf-inserting part 14 also has a
separate use as a ball marker on a golf green during putting as
shown in FIG. 8, hence the pointed shank 21. The parts of said
embodiment 10 can be finely finished and the top of the head 20
personalized so as to render said embodiment 10 an object highly
prized as well as useful.
It will thus be seen that there has been provided by my invention
an improved golf tee in which the object hereinabove set forth
together with many thoroughly practical advantages has been
successfully achieved. While a preferred embodiment of my invention
has been shown and described it is to be understood that variations
and changes may be resorted to without departing from the spirit of
my invention as defined by the appended claims.
