Description
FIELD OF THE INVENTION
[0001] The present invention relates to a measuring gauge that can
improve the precision of the angles measured for clubheads (for
woods or irons), and more particularly to a measuring gauge that
uses an adjustable measuring base to collocate with an assistant
measuring base to measure the lie angle, slope, face angle, and
gravity angle of golfclubs with different specifications and sizes
than can improve the precision of measurements and reduce
errors.
BACKGROUND OF THE INVENTION
[0002] Most of the present methods used for measuring the angles of
golfclubs generally require a tester to hold the golfclub by hand
and press the striking face of the clubhead against the measuring
gauge, and then the tester determines the angles of the striking
face by experience and visual inspection. Such traditional methods
of measuring the angles of a striking face of golfclubs can achieve
the intended purpose, but the following shortcomings are still
found in its practice:
[0003] 1. Since all testers rely on their personal experience to
measure angles of a striking face golfclub (regardless woods or
irons) in longitudinal and transversal directions and such test is
carried out to measure roughly by visual inspection, therefore the
measurement and process are not accurate or precise.
[0004] 2. Such a method takes much time and effort for the test,
and may even cause defections (since the golfclub is held by hand
it is not easy to it steady, therefore, errors in measuring the
striking face may occur. As a result, such inaccurate methods
cannot achieve the intended effect.
[0005] 3. It is inevitable to have an inaccurate measurement of
club angles by visual inspection. Thus, it will affect the striking
effect of a golfclub in practice, or even ruin the reputation of
the manufacturer.
SUMMARY OF THE INVENTION
[0006] In view of the foregoing shortcomings of the prior art, the
inventor of the present invention overcame the shortcomings by
developing the measuring gauge in accordance with the invention.
The features and advantages of this invention are given below:
[0007] 1. The invention uses an adjustable measuring base and an
assistant measuring base together to measure angles such as the
face angle, lie angle, gravity angle, and sole angle, etc of
golfclubs to improve the precision of measurement and maintain
quality standards.
[0008] 2. The protractor used in the assistant measuring base of
the invention can move along a circumference and align with the
groove line of the striking face to improve the precision of
measurement and lower the error rate.
[0009] 3. The base for fixing clubheads according to the present
invention adopts a screw rod as the axle center, so that the base
can rotate left or right along the circumference, and the under
side of the clubhead base is parallel to the horizontal base before
measuring the angle in order to obtain a more accurate
measurement.
[0010] 4. In the measurement according to the invention, the angle
measured by the protractor is adjusted to the angle of the
measuring clubhead to achieve a corresponding angle measurement,
and thus reduce errors.
[0011] The primary objective of the present invention is to
overcome the aforementioned shortcomings by providing a clubhead
measuring gauge.

board 200. An adjusting member 203, 204 is disposed each at the
center of the upper board 201 and the lower board 202 respectively,
and a screw hole 206, 207, 208 is disposed on the upper board 201,
lower board 202, and adjusting member 203, 204 for receiving a
screw rod 21 with a handle 210, and being rotated selectively in a
clockwise direction or a counterclockwise direction to drive the
adjusting member 203, 204 to move up or down. A pivotal member 22
is coupled to another side of the erect board 200 and an end
section 224 having a through hole 223, and a channel 220 embedded
into an embedding member 230 of a positioning member 23. An axle 24
passes into the through hole 223 of the end section 224 to define a
fulcrum, so that a fixed groove 231 is disposed at one end and the
positioning member 23 movably coupled to a screw 232 that can be
rotated upward, and a plate member 221 extended from the rear end
of the pivotal member 22, and a screw hole 222 disposed on the
plate member 221 for moving the adjusting member 203 up and down to
fix the protractor for measuring woods or irons, and facilitate the
measurement of the face angle of the wood 7 of the golfclub 70
(FIG. 5) or iron 8 (FIG. 9). Further, the fixed member 20 is fixed
into the channel 10 of the base 1, and a screw hole 205 is disposed
on one end of the fixed member 20 for mounting an assistant
measuring base 3 by screws.
[0027] The assistant measuring base 3 comprises a long block 30
having a long channel 300 for adjusting the screw hole 205 disposed
on the fixed member 20 back and forth by a fixing screw 31, and a
measuring board 32 positioned by a positioning rod 320 is fixed on
the upper front end of the assistant measuring base 3, and the
measuring board 32 at one side has a standard side 321.
[0028] The fixed base 4 (as shown in FIG. 4) is coupled to the
front end of a link member 40 having a screw hole 401, and a screw
rod 400 is screwed into the screw hole 401 and coupled to a
connecting member 41 by a screw thread. An embedding groove 410 is
disposed inside the connecting member 41 and engaged with an
embedding member 420 with a shape corresponding to that of the
embedding groove 410 is protruded from the rear end of an engaging
member 42. A V-shaped groove 421 is disposed at the center of a
front end of the engaging member 42 and a latch member 422 having a
latch groove 423 for being pivotally coupled at each end by a screw
bolt 425. A screw hole 424 is disposed at one end of the side of
the engaging member 42 for mounting a positioning member 43 by a
screw 434. A protruded edge 430, 431 is extended vertically from
both sides of the positioning member 43 respectively, and such two
protruded edges 430, 431 have a hanger 432 and a latch section 433
disposed in opposite directions corresponding to the hanger 432, so
that the wood 7 is hung onto the hanger 432 and another
corresponding latch section 433 is latched to prevent the wood 7 of
the golfclub 70 from moving up and down. Further, a protruded base
440 having an adjusting base 44 is coupled to the engaging member
40 on the other side by screws. An arc side 441 having a quarter of
the circumference is disposed at the top of the adjusting member
44, and a calibration 442 is marked on the edge of the arc side 441
and has an arc groove hole 443 with the same curvature as that of
the arc side 441. A screw rod 444 of the adjusting base 44 is used
to move the fixed base 4 along the arc groove hole 443, so that the
wood 7 or iron 8 of the golfclub is clamped in a position for
measuring its lie angle, and a movable base 5 is fixed on one side
of the protruded base 440 by screws.
[0029] A calibration 50 is disposed on one side of the movable base
5, and an arc groove 51 with the same curvature as that of the
movable base 5 is evacuated from the movable base 5. In the
meantime, the protruded base 440 of the adjusting base 44 is
rotated to a measuring lie angle and fixed into a position by a
screw rod 52.
[0030] With the foregoing components, a fixed base 4 capable of
being rotated along a circumference, an adjustable measuring base 2
for fixing a protractor 6 and allowing the protractor 6 to move in
an increasing angle or a decreasing angle with respect to the
adjustable measuring base 2, and an assistant measuring base 3
having a standard side are coupled separately to a base 1 with a
horizontal flat surface. Since the protractor 6 is disposed on the
adjustable measuring base 2, the face angle of the clubhead can be
adjusted to match the measuring angle, thus achieving the purpose
of reducing errors in measurement and improving precision.
[0031] Further, the sole surface of the wood 7 or the iron 8 is
attached flatly on the horizontal base 1 to collocate with the left
or right rotation of the fixed base 4, adjust the angle of
measurement for the clubhead structure and achieve the expected
precision.
[0032] Please refer FIGS. 5 and 6 for the procedure of measuring a
lie angle according to the measuring method of the present
invention. Firstly, the clubhead 7 of the golfclub 70 is placed
into a V-shaped groove 421 of the engaging member 42 and fixed by a
latch member 422. Then, an edge of the testing board 32 on the long
block 30 of the assistant measuring base 3 is used to press against
the transversal groove 72 on the striking face 71 of the wood 7. If
they do not match, then the golfclub 70 is moved downward along the
arc groove hole 443 by the engaging member 42 until the edge of the
testing board 32 matches with the transversal groove 72 for the
pressing. A user can obtain the angle of elevation measured by the
calibration 442 on the arc side 441.
[0033] Please refer to FIG. 7 for the view of the action taken for
measuring the sole angle of the wood 7. Firstly, the wood 7 is
fixed to the engaging member 42 by the golfclub 70, and the
engaging member 42 has a rotary axis at its center and is fixed by
a screw rod 400, such that the engaging member 42 can rotate to
drive the wood 7 thereon to attach the sole of the wood 7 flatly on
its horizontal surface, and then the protractor 6 fixed onto the
outer side of the measuring board 61 of the assistant measuring
base 3 is rotated and positioned vertically to prop up directly
onto the striking face 71. The measured sole angle can be obtained
from the protractor 6.
[0034] Please refer to FIG. 8 for measuring the face angle of a
wood 7 (or FIG. 9 for the iron 8). Similarly, the wood 7 or the
iron 8 is placed onto the base 1 by the engaging member 42, and the
protractor 6 movably coupled to the pivotal member 22 of the
adjustable measuring base 2 is adjusted to the same angle as that
of the transversal groove 72 on the striking face 71 of the wood 7
(or transversal groove 82 of the striking face 82 of the iron 8),
and presses the striking face 71, (81). The measured face angle can
be obtained from the protractor 6.
[0035] Please refer to FIG. 10 for measuring the gravity angle of a
clubhead using the present invention. Firstly, an iron 8 (or a wood
7 as shown in FIG. 11) is fixed to a hanger 432 and a latch section
433 disposed correspondingly in opposing directions on two
protruded edges 430, 431, so that the club 80 is placed
horizontally and the iron 8 droops naturally. Then, the protractor
6 movably couples to the pivotal member 22 of the adjustable base 2
and rotates to a vertical fixed position, pressing the inner side
60 of the measuring board against the striking face 81 of the iron
8. The measured gravity angle of the striking face can be obtained
from the protractor 6.
[0036] Finally, refer to FIG. 12 for measuring the progression of
the center of a club with the present invention. The wood 7 is
fixed by aligning the center of the club with a standard line 14 on
the base 1, and then the long block 30 of the assistant measuring
base 3 presses against the end surface 73 of the striking face
directly. The measured progression of the center of the club can be
obtained from the calibration.
