Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a wedge club suitable for a wedge shot, particularly a bunker shot mainly used in a bunker and an approach shot on a through-the-green other than the bunker.

[0002]

[Prior art]

 In the past, it was said that for players, “make score is an approach” or “a scoring zone is around the green”. Everybody experiences it as important.

As is well known, for a player, a ball in a bunker arranged on a golf course depends on the lie of the ball dropped on the sand, the type of the sand, the dropping position, and the distance to the pin on the green. It is necessary to make a shot under all conditions, such as when putting one shock in front of the green without directly dropping it on the green or on the green.This is common not only for bunkers but also for shots from through the green. .

Normally, in a bunker shot, it should be judged that the ball on the sand is not directly hit by the impact, and the ball on the sand is sunk to some extent regardless of whether the lie is good or bad. Explosion shot that uses the action of hitting the ball and using the sand as a cushion to raise the ball.

That is, to raise the ball on the cushion, it is the same as hitting the cushion with the club head and using the cushion. Therefore, depending on the amount of sand taken, a home run that hits the ball directly to go over the target point, or, on the contrary, a miss shot such as a hackle that can not punch the club head because it is hit too much (through from other than the bunker It was a mistaken shot on the green that caused the player to hit the ball in front of the ball, which caused the player to lose the score.

As shown in FIG. 6, a conventional sand wedge head has a heel portion (b) connected to the tip of the shaft (a) as one apex, and extends in a direction orthogonal to the swing direction, that is, in front of the player's body. A substantially triangular face (C) having two sides extending toward the front is formed so as to incline (loft) about 35 degrees with respect to the horizontal plane L while facing the front in the swing direction. On the back side, a sole (e) extending horizontally from the leading edge round (d) to the rear in the swing direction is formed as it is, and the sole width is expanded to increase the explosive force during use. is there.

In addition, before and after the sole (e), each club has a rounded round.

[0008]

[Problems to be solved by the device]

 In this way, if the sole (e) is thick and bulged, it will be heavy, and the explosive force will certainly increase, but for golfers who are otherwise weak, they will lose the resistance of the sand and cause a mistake, especially The shot is weak for a weak woman.

On the other hand, for a player with a certain level of high level, the front and rear of the big sole and the round of the sole width are obstacles to an accurate shot, and cannot release an accurate shot to be predicted. There is also.

[0010] Conventionally, in an attempt to improve the above-mentioned object, in a club head of a metallic short iron, the shape of the flat plate striking surface just behind the scoring area can be formed including the vicinity of the sole edge. Only a wide range, with a uniform and smooth thin wall, and with a thicker rim around the outer edge, perform a half or full swing with a pitch shot to reach the hole. (Japanese Patent Laid-Open No. 53-127038), a part of the sole of the iron head is cut to reduce the sole area to reduce the resistance of the turf, or a through hole is formed on the back of the head from the surface of the sole. The sand of the bunker passes through the through hole to prevent dripping and facilitates swing-out (Japanese Patent Laid-Open No. 59-174171), iron golf club head ho By reducing the amount of material that forms the shell and bridge portions and transferring a weight equivalent to this to the blade, it is possible to contribute to the transmission of momentum to the golf ball (JP-A-63-216584), Ti or its alloys. A hard layer made of a Ti intermetallic compound is provided on the sole surface of the club head made of a material that improves the wear resistance of the sole portion, thereby providing a head structure suitable for iron wedge clubs, etc. (Kaihei 4-297283), and by cutting out a part of the metal part on the back side of the sole part and substituting it with a non-metal having a low specific gravity such as fiber reinforced plastic, the weight of the head is changed to the toe side and the heel side. Distribute a large amount to balance the toe and heel, widen the sweet area of the head, make a stable shot, and make a mistake The head wobbling is reduced during wobbling (Shokai 63-158365), while the wedge club's sole is provided with a negative rake angle to the sand, and the ridgeline of the swinging edge of the sole is narrowed in plan view. In contrast, by tilting the head at a certain angle or more, the resistance when the head is driven into the sand is reduced, the removal from the sand is improved, and the orientation of the head is easily controlled. One (actual fair 1-62866) is provided and disclosed.

In order to remedy the above-mentioned drawbacks, the present invention is capable of using a bunker or a non-bunker such as a rough lane or a fairway, and hitting the ball directly without interposing sand without causing a home run. On the contrary, even if you hit the front of the ball with a dull feeling, you can overcome the rough such as sand resistance and contradictory, and you can take an explosive shot and a approach shot without wedges. The purpose is to provide a dual-purpose wedge club.

[0012]

[Means for Solving the Problems] In order to achieve the above object, the wedge shot iron club according to the present invention has a head with a heel vance extending to the shaft in a plane as one apex with respect to a swing direction. Leading edge lands that extend in a direction substantially orthogonal to each other, the highest face that extends rearward with respect to the swing direction, the tip of the leading edge land, and the tip of the highest face in a swollen curved shape. With a face that is almost the same as a normal wedge surrounded by the connecting wedge part, the sole width of the sole part that extends continuously to the leading edge land is the width of the sole. It is carved along the land, and from the heel part of the sole, the sole central land, center vance, toe vance. Connecting, the central saw Le width lies in the formation of the cut made the sole recess in a curved shape in cross section arcuate.

[0013]

[Action]

 Explaining the use of the iron club for wedge shot according to the present invention, when the head is driven into the sand, the head 1 receives a downward force due to the slope effect of the face 6 having a positive rake angle with respect to the sand. Is the same as the conventional sand wedge.

However, according to the wedge shot iron according to the present invention, as shown in FIG. 5, the entire sole width of the sole portion 7 continuously extending from the leading edge land portion 4 is reduced. A sole recessed portion 12 is formed over the entire area. Therefore, the leading edge portion 4 having an acute angle is formed by cutting into a curved shape with an arcuate cross section, and the sole width at the rear end connected to this in the width direction. Due to the action of the rear edge 13, the head can perform the action of raising the ball by using the sand as a cushion (explosure rosin shot) without deeply digging into the sand. That is, when the leading edge portion 4 of the sole recessed portion 12 formed on the entire sole portion first touches the sand and then the face 6 further moves in the swing-out direction, the rear edge 13 of the sole width becomes thin. The sand taken is conveniently braked, acting as an explosive shot with the usual thin techniques.

What is different from the conventional thick wedge sand wedge shot is that it can be used in the same method without affecting the sand type such as softness, hardness, and sand coarseness due to the effect of rain. Is.

[0016] In addition, the lie of the ball in the bunker is completely in the center of the fried egg or fried egg (crater state), and the ball is completely submerged, and the crater is slightly shallower like fried egg. Even if it is in a shape, the leading edge portion 4 is sharply cut according to the sand wedge according to the present invention. (In the case of a normal thick vance, the point where the club head is inserted is Although it requires a technique to drive the sole of the club head backward by about two times in front of a normal bunker shot, it is extremely easy to hit the ball by hitting the sharp edge with respect to the center ball. it can.

[0017]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

2 to 4 show a shape and a cross section of a head 1 of an iron club for wedge shot according to the present invention. The head 1 has a heel bans 3 extending on the shaft 2 in a plane as one apex, and a leading edge land 4 extending in a direction substantially orthogonal to the swing direction (arrow direction) and a swing direction in the swing direction. Surrounded by the highest face portion 5 that extends backward while inclining, the leading edge of the leading edge land portion 4, and the toe edge portion (face length) that connects the leading end of the highest face portion 5 in a swollen curved shape. It has a face 6 similar to a normal wedge.

In this invention, the difference from the ordinary sand wedge or approach wedge is that the sole width of all the parts of the sole part 7 continuously extended to the leading edge land part 4 is along the land of the sole. As shown in FIG. 5, it is connected to the sole center land 9, the center bans 10, and the toe vance 11 from the heel part vance 8 of the sole part 7, and the center of the sole width is curved in an arcuate section. That is, the sole recessed portion 12 that has been abraded is formed.

Therefore, as shown in FIGS. 2 to 4, in the cross section of the sole recessed portion 12, the edge land of the leading edge portion 4 and the rear portion 13 of the sole width all form an acute edge.

[0021]

[Effect of device]

 According to the wedge shot iron club of the present invention, when the head is driven into the sand, the head receives a downward force due to the slope effect of the face having a positive rake angle with respect to the sand. At this time, according to this invention, the sole recess is formed over the entire width of the sole in the entire portion of the sole that is continuous with the leading edge land.

Therefore, due to the action of the leading edge having an acute angle, which is cut into a curved shape with an arcuate cross section, and the rear edge of the sole width which is connected to this in the width direction, the head of the sole recess digs deep into the sand. You can use the sand as a cushion to make the ball soar.

At this time, when the leading edge portion of the sole concave portion formed over the entire sole portion first touches the sand, and when the face further moves in the swing-out direction, the rear edge of the sole width becomes The surface of the thinly-sanded piece has a convenient breaking effect, and it is possible to make a shot that cuts into the thin sand, which is the conventional high-level sand technology.

According to this usage method, a good shot can be made not only from the lie in the bunker but also from the apron around the hard green and the rough through the green (deep rough and thin fairway of grass).

Further, the excellent feature of the present invention is that since the sole recess is formed by connecting to all the parts of the sole, for example, the hardness, softness, and weight of all lie and sand against the ball in the bunker, Even for light sand, the action of the acute-angled leading edge provided in the sole recess and the trailing edge provided at the trailing edge of the sole width makes it possible to strike the ball extremely easily.
