The present invention is more related to a round golf club head in the form of "iron material", especially an iron shaft with a surrounding, concave-back geometry, which ensures the mass distribution of the round golf club head we desire. And at the same time maintain excellent batting quality. Golf club heads in the form of iron are typically made by casting or forging metal. The iron golf club head system includes ~ hitting surfaces, and its inclination will change with different club numbers in a group of golf clubs. Therefore, lower-numbered irons, such as No. 1 to No. 4 irons, are called "long irons", and their inclination from the vertical line of the hitting surface is higher than that of "short irons". The face is small, and the short irons are irons with a higher number in a group of golf clubs, such as an eighth iron, a nine iron, and a PW (pitching wedge). One of the goals of the improved iron form golf club head design is to redistribute the mass of the golf club head to its surroundings, substantially surrounding the center of the face of the golf club head. The center of the batting surface is roughly equal to the ideal batting area, or the so-called "sweet spot". The distribution of golf club head masses to its surroundings, that is, the surroundings are heavier, tends to enlarge the sweet spot. Many commercially available iron-type clubs have appeared on the market. The central recess at the back of the heavy-duty iron-type club head is suitable for providing different functional or decorative elements at the same time. The surrounding weighted parts can be roughly described as a group of wall parts located on the back side of the iron-type golf club head, and generally in a ring shape. 3 This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ^ 7 ----------- Order --------- line (please read the notes on the back before filling this page) A7 1230083 _________B7 V. Description of the invention ( ) And these wall parts form a rear recess. The lowermost wall portion of the surrounding weighting portion extends along the bottom of the back side of the golf club head, and the lowermost surface of the wall portion forms the bottom surface of the golf club head, which is hit by a golf club head The golf ball comes into contact with the ground. The uppermost portion of the surrounding weighting portion extends along the top of the back side of the golf club head, and its top surface intersects the hitting surface of the golf club head. This part of the surrounding weighting part is generally called the top rail of the iron type golf club head. The top surface of the top rail can be easily seen by a player when preparing to hit a golf ball or during a shot. The surrounding weighting portion defines two end walls at the same time. One end wall is located at the toe end on the back side of the golf club head, and the other end wall is located at the golf club. At the heel end on the back side of the head, the toe wall and the heel wall are typically on the heel and the weighted parts around the golf club head, respectively, on the heel and The sole wall and the top rail part connected at the toe corner are integrally formed. The surrounding weighting portions that define the back recess of the golf club head collectively form a generally ring-like portion, which is commonly referred to as the perimeter weighting. Ο The first has been proposed is In this golf club head, a peripheral weighted portion is formed, and in particular, its shape can be adjusted for mass distribution, for example, by increasing the mass of the lower or bottom formed wall portion and at the same time reducing the surrounding weighted iron type club head.

Description of the invention () The form of the characteristic aperture or groove in the top rail, The position and hollow capacity are different from each other in this group of related golf clubs. For example, as illustrated in Figures 8a, 8b, and 8c, the number of holes or grooves in a group of related golf clubs can be changed. Therefore, the head 4 series corresponding to the long iron No. 2 may include five grooves 4 1 to 4 5 in the top rail 13. At the same time, for example, the middle-numbered club system of the fifth iron in the eighth " b picture may include only three grooves 4 7-4 9. These three grooves 4 7-4 9 series may be the same as or different from the grooves 4 1-4 3 in the exemplary second iron as illustrated in the eighth figure. The eighth b figure has three grooves 4 7 — 4 9. The center of gravity of the golf club head with respect to the top rail 1 3 can be located approximately the same as the eighth a figure with the groove 4 1 -4 The position of the center of gravity of the club head of the 5th golf club has substantially the same relationship with the top rails 13 of the two golf clubs. What this shows is that the reduction in the number of grooves between the second and fifth irons, and therefore the reduction in weight removed from the top rail, will cause the center of gravity to move slightly upward in the vertical direction, as if by The relationship between the centers of gravity G 4 0 and G 4 6 in the eighth diagrams a and eighth b diagrams.

Here, the distance d 9 between the capacity center 6 2 of the groove 6 1 and the axis 65 is greater than the corresponding distance d 5 of the fifth iron of the same group of related golf clubs. Similarly, the center of gravity of the 9th iron G 6 0 is horizontally moved more toward the heel portion of the golf club. This is the center of gravity 5 of the 5th iron and the 2nd iron that are related to the same group of golf clubs, respectively. 7 and G 5 3 are obtained in comparison.

Similarly, different combinations of groove shape, number, location, and total capacity can be selected to provide the desired mass distribution to move the center of gravity of different golf club heads in a group of related golf clubs. As mentioned earlier, a particularly preferred arrangement of a group of grooves is illustrated in the eleventh figure, where the central groove 66 is of medium length and is slightly shorter in length than the central groove The grooves 6 7 and 6 9 on both sides of the groove 6 6 are shorter end grooves 6 8 and 70 respectively. It is also possible to create a golf club head in the form of an iron material with a part of a hollow top rail by creating a hole 3 3, the hole □ 3 3 is opened laterally through the head surface 1 7 And extends within and parallel to the top rail 13 as illustrated in the fifth to seventh figures. This elongated orifice will typically be produced by drilling or boring, although other manufacturing methods can be used by us. In this embodiment, the capacity of the hollow orifice or groove 33 is mainly determined by its length, and to a lesser extent by the diameter or size of the surface opening 34. For example, the length of the opening or groove 33 may include between 10% and 90% of the total length of the top rail 13 and its diameter may be up to about 3 mm. The position of the center of gravity of a particular golf club head can be changed based on the total amount of mass removed by creating the grooves of this type of perforation. 19 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ‘^ Order --------- Φ (Please read the precautions on the back before filling this page)

Description of the Invention () It will be known to me that the advantageous iron material form golf club head system of the present invention provides a practical, economical, and unique and changeable way to To achieve the purpose of the invention. As explained, for example, in the preferred embodiment of the eleventh figure, the production of the elongated grooves 6 6-70 produces two ingeniously connected by bridging materials that separate the grooves Continuous and parallel steel beams. This system allows the manufacture of a golf club head, where the top rail system can have the same or even less mass, while having an increased depth dimension in a generally vertical dimension along the golf club surface at the same time. This system enables the top rail to provide reinforcement or stiffness to the surface of the golf club, and it greatly enhances the golf club's unique feel during golf strokes. Furthermore, as discussed herein, the emergence of the advantageous grooves of the present invention provides a highly correct pattern of redistribution in the surrounding weighted portions, thereby allowing the center of gravity of the golf club head to be desirably repositioned. In addition, the unique and reinforced structure of the grooved top rail will result in a unique concave back-type golf club head with an increased weight in the form of iron, which will easily withstand not only during golf strokes, but also for The force exerted on the club head when it is bent to make the golf club head suitable for a single player. In addition, in order to avoid the advantageous orifices, slots, or grooves of the present invention from being clogged with dust or other substances that can change the desired mass distribution in a single golf club head, such as The orifices, slots, or grooves can be filled with a low-density material, such as a polyurethane foam material, to prevent the entry of dust or other foreign materials. According to a specific embodiment, the orifice, narrow 20 paper rule ¥ ^ Chinese National Standard 297 'Sign-. ^ -------- 1 --------- (Please read the note on the back first Please fill in this page again) A7 1230083 ____________ ^ _______ B7 ___ __-^ ~~ V. Description of the invention () The total capacity of the groove or groove is typically expressed between the golf club head || Between% and 5% The capacity of the groove provides the material capacity that can be redistributed to other parts of the golf club head (such as other parts of the surrounding weighted part).
