Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a golf club head with a
multiple dimpled face, particularly to a golf club head of iron
golf clubs or wood-type golf clubs having a improved face to
enhance functions of golf clubs.
[0002] Generally, a golf club head of iron golf clubs or wood-type
golf clubs provides with a number of at a face with which contacts
the surface of golf balls to prevent golf balls from slipping
during impact with golf balls, to stop golf balls on putting green
without running, if a golf club is an iron golf club, and to
achieve back-spin of golf balls.
[0003] However, for many of professional golfers and amateur
golfers, although there is a somewhat difference in terms of
technical ability between them, all that matters is a directional
behavior and driving distance of balls struck by them. It is known
that professional golfers have not any problems to control their
driving distance of balls in the existing golf course, but all of
them do not satisfy to control the directional behavior of balls
and the running of balls on putting green.
[0004] Furthermore, many of amateur golfers do not satisfy to
control the directional behavior of balls in the fairway. In the
directional behavior of balls, it includes three behaviors, that
is, a straight trajectory behavior from a stable swing and an ideal
striking of sweet spot during impact with golf balls, a hook
behavior from a premature winding of a closed club head due to an
unstable setup of a golfer and from a sliding of golf balls during
contact with a club face, and a slice behavior from an unstable
setup of a golfer and from contacting golf balls with an open club
face.
[0005] Known golf club head has disadvantage that a club face is
provided with a number of horizontal grooves, so that, though the
club face having the horizontal grooves prevent a golf balls from
sliding upwardly and downwardly and provide a spin to golf balls
during impact with golf balls, it is difficult to prevent the golf
balls from sliding on right and left.
[0006] The golf balls will have good directional behavior when the
golfer attends to his best conditions of swing, when the golf balls
impact at the sweet spot of face, and when the target and the face
are squared, otherwise the golf balls will have poor directional
behavior. Particularly, when the target and the face are not
squared, the golf balls slip on the face so that the golf balls
will have poor directional behavior.
[0007] Further, it is difficult to effectively provide a spin to
the golf balls by means of the club face having only horizontal
grooves. To improve directional behaviors such as the hook or the
slice, an attempt is proposed to permit the weight of the club head
to be distributed for good directional behavior of golf balls. But
as this attempt is little effective, the golf club to which this
attempt is applied are not used widely. Further, in the case of the
short iron(#7, #8 or #9 iron) clubs or wedge(pitching or sand
wedge) clubs, because of having small loft, they have effects for
stopping golf balls at the dropping site without running and
achieving back-spin of golf balls, but in the case of the middle or
long iron clubs having large loft, the back-spin of golf balls is
decreased, so that the golf balls may often miss to drop on the
putting green.
SUMMARY OF THE INVENTION
[0008] One object of the present invention is to overcome the above
mentioned problems associated with the golf club head having
horizontal grooves at the face.
[0009] Another object of the present invention is to provide a golf
club head of iron golf clubs or wood-type golf clubs having a
improved face to enhance functions of golf clubs.
[0010] And another object of the present invention is to provide a
golf club head to allow a directional behavior of golf balls to be
good. If one can obtain perfect technique in golf swing, one may
play golf of high level with the golf club of the present
invention.
[0011] According to the present invention, the present invention
provides a golf club head having a neck to which a club shaft is
connected, a bottom sole, a top edge, and a face, wherein the face
is provided with a number of dimples in the form of circle.
[0012] Preferably, the rows of dimples are arranged diagonally in
the face in reference to the bottom sole line, such that the
dimples are staggered upwardly and downwardly and spaced at regular
intervals. The face may be provided with a number of dimples, such
that the row of dimples are arranged horizontally in reference to
the bottom sole line. The dimples may be a form of a ellipse.
[0013] The present invention will be better understood from the
following detailed description taken with the accompanying
drawings, in which:

DETAILED DESCRIPTION
[0021] Referring to FIG. 1 and FIG. 3a, the illustrated golf club
head 10, in the form of an iron golf club, has a neck 12 to which a
club shaft(not shown) is connected, a bottom sole 14, a top edge
16, and a face 18. The face 18 is provided with a number of dimples
20 according to the present invention. The rows of dimples 20 are
arranged diagonally in the face 18 in reference to the bottom sole
line, such that the dimples are staggered upwardly and downwardly
and spaced at regular intervals.
[0022] The golf club head 10 having the face 18 in which a number
of dimples 20 are formed according to the present invention may
effectively prevent a golf balls from sliding in every direction.
Specially, the golf club head according to the present invention
provides a reduction of sliding phenomenon between the face and
golf balls, such that the face according to the present invention
will prevent the golf balls from sliding at the dimples g when the
edge of dimples of the face contacts the portion adjacent of
dimples of golf balls.
[0023] The face formed with a number of dimples may provide a
desired impact feel to golfer due to the reduction of sliding of
golf balls during impact with golf balls and create a good
directional behavior of golf balls.
[0024] And when the golf balls is struck by the face, the golf
balls could be stayed at the face on comparatively long time due to
the increasing of contact surface between the balls and the face,
so that a directional behavior of golf balls is improved and, in
the case of the middle or long iron, the spin effect of golf balls
is increasingly improved.
[0025] FIG. 3b shows the another embodiment of golf club head 10
according to the present invention, which is provided with a number
of dimples 20 at the face 18 such that the row of dimples are
arranged horizontally in reference to the bottom sole line.
[0026] The embodiment of the present invention shows a superior
spin effect of golf balls than that of former embodiment, but shows
the experimental results of reduction of the directional
behavior.
[0027] FIG. 4 shows a further embodiment adapted to an iron club in
which a number of dimples 20' in the form of ellipse are formed at
the face.
[0028] FIG. 5 shows a embodiment adapted to a wood type golf club
in which a number of dimples 20 are formed at the face 18 such that
the rows of dimples 20 are arranged diagonally in the face 18 in
reference to the bottom sole line, such that the dimples are
staggered upwardly and downwardly and spaced at regular intervals,
similar to the golf club head shown in FIG. 3a.
[0029] The inventor has obtained the experimental results of
difference between the iron club of the present invention and the
existing iron club in term of the directional behavior of golf
balls and the spin effect. Also, The inventor has obtained the
experimental results that the golf balls struck by the existing
iron club got out of a line extending on the target by about 20
yards when the golf balls dropped after flight of about 150 yards.
But the golf balls struck by the iron club of the present invention
got out of a line extending on the target no less than about 10
yards in hook or slice.
[0030] Furthermore, The inventor has obtained the experimental
results that the golf balls struck by the iron club of the present
invention stopped on putting green without a conspicuous running,
if a golf club is an iron golf club. But the golf balls struck by
the existing iron club have run remarkable distance from the
dropping site.
