Description

  The present invention relates to a golf club head, and more particularly to a golf club head in which reinforcing ribs are formed on the inner surface of the hollow structure.

  Conventionally, in order to adjust the center of gravity of a golf club head, a counterweight is sometimes set on the inner surface of the hollow structure.

Incidentally, some golf club heads have an enlarged hitting surface for hitting.
However, when the striking surface is enlarged, the entire golf club head is enlarged accordingly, so that it is necessary to reduce the thickness in order to reduce its weight, and it is also necessary to reinforce as the thickness is reduced.

As for the reinforcement, as shown in FIGS. 8 and 9, a plurality of ribs 6, 6,... Are usually arranged in a lattice pattern on the back surface of the striking plate 51 whose front surface is a ball striking surface and the back surface of the crown plate 52. (See Patent Document 1).

  The present invention aims to provide a golf club head in which a rib placed on the inner surface of the hollow structure serves as a reinforcing weight and also acts as a counterweight, and the center of gravity of the entire golf club head can be moved backward. Its primary purpose is to do.

  A second object of the present invention is to provide a golf club head having an enlarged striking surface so that the weight is not increased and the overall strength is not weakened.

  In order to achieve the above object, the present invention has a striking plate which hits the ball in front and hits the ball on the basis of the posture immediately before hitting the ball, and a sole, and the leading edge thereof is the striking plate. A golf club head having a hollow structure having a head main body that is connected to and integrated with the upper body and a crown that covers the opening. Provided is a golf club head in which a reinforcing rib group is installed on the inner surface so as to sandwich a distance from the back surface.

  The head main body or the crown provides a golf club head made of a light weight material such as carbon fiber.

  The golf club head according to the above configuration is provided on the inner surface of the hollow structure excluding the back surface of the striking plate so that the reinforcing rib group is placed at a distance from the back surface. The structure is not weak and the center of gravity of the head moves backward.

  Further, since the head main body or the crown is made of a light weight material such as carbon fiber, the striking surface is enlarged without increasing the weight.

  Hereinafter, a preferred embodiment of a golf club head according to the present invention will be described with reference to the drawings. In the figure, like parts are denoted by like reference numerals.

First, a golf club head according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the golf club head of the present embodiment has a striking plate 10 on the front and hitting the ball 11 on the front, and a sole 21 on the basis of the posture immediately before the moment of hitting the ball, The front edge 22 is connected to and integrated with the striking plate 10 and has a hollow structure having a head main body 20 in which an opening 23 is left above and a crown 30 covering the opening 23.

Further, the reinforcing rib group 4 is installed on the inner surface of the crown 30 so as to sandwich a distance of about 2 cm from the back surface 12 of the striking plate 10.
The reinforcing rib group 4 is composed of a plurality of reinforcing ribs 41, 41,...

In the present embodiment, both the crown 30 and the reinforcing rib group 4 are made of carbon fiber and integrated, but those made of different materials may be used.
Although this embodiment discloses a wood head, it is also applicable to an iron head.

  Since the crown 30 and the reinforcing rib group 4 of the present embodiment are made of lightweight carbon fibers, even if the size of the golf club head increases to enlarge the striking surface 10, the weight increases. Can be offset. Further, the reinforcing rib group 4 of the present embodiment is installed on the crown 30 so as to sandwich the distance from the back surface of the striking plate 10, so that the center of gravity is biased behind the conventional one.

Next, a modification of the present embodiment will be described with reference to FIG.
The reinforcing rib group 4 in this modified example is composed of a plurality of reinforcing ribs 41, 41... Crossed at a distance from the left and right and back, and the other structure is exactly the same as that of the above embodiment. I will omit the explanation here.

Then, another modification of the present embodiment will be described with reference to FIG.
The reinforcing group ribs 4 in this modification are each arcuate, and are composed of a plurality of reinforcing ribs arranged in series with a distance in the front and rear, and the other structure is the same as that of the above embodiment. Since it is exactly the same, I will omit the explanation here.

Furthermore, a further modification of the present embodiment will be described with reference to FIG.
The reinforcing rib groups 4 in this modification are each arcuate, and are composed of a plurality of reinforcing ribs intersecting at a distance from left to right and back and forth, and the other structures are the same as in the above embodiment. Since it is exactly the same, I will omit the explanation here.

  In the embodiment and some modifications thereof, all the reinforcing rib groups 4 are provided on the inner surface of the crown. What is necessary is just to install so that the back surface 12 of the striking board 10 may be pinched | interposed into the position in any one of the inner surface except. The example is given as follows.

A golf club head according to a second embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 6, in the golf club head of the present embodiment, the head body 20 is made of carbon fiber. In addition, a reinforcing rib group 4 is integrally formed on the inner surface of the sole 21 of the head body 20. Since the other structure of this embodiment is exactly the same as that of the first embodiment, the description thereof is omitted.

  The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof. Accordingly, the preferred embodiments described herein are illustrative and not limiting.

  As described above, in the present invention, the crown and the reinforcing rib group of the golf club head, or the head body and the reinforcing rib group are made of carbon fiber. Even if it becomes larger, the weight does not increase.

  Further, since the reinforcing rib group is installed on the inner surface excluding the rear surface of the striking plate so as to sandwich the distance from the rear surface, the center of gravity of the head moves close to the rear toe, so that the moment of inertia and swing of the head The speed is increased, and the flight distance of the ball can be effectively increased.
