CROSS-REFERENCES TO RELATED APPLICATIONS

This application claims the benefit of Chinese Patent Application No. 201910125613.0, filed Feb. 20, 2019, and incorporates the disclosure of the application by reference.

TECHNICAL FIELD

The present disclosure relates to golf equipment and, in particular, to a golf putter head and a putter.

BACKGROUND OF THE TECHNOLOGY

In golf, players first use wood and iron bars to hit the golf ball onto the green, and then commonly hit the golf ball toward the hole with a putter. A putted ball is affected by the smoothness of the green surface, soil moisture, grass mat thickness, grass species and so on. The golf ball typically also has a higher rolling speed on the green as compared to other portions of a golf course. Therefore, to smoothly put the golf ball into the hole as well as enjoying the play and winning the game, the putter must have better stability and higher fault tolerance to achieve precise ball control.

After testing the nine common putters sold in the market, it was found that the weight, the face technique and the hitting point of a putter head are working together to influence conversion rate. The inconsistency of the hitting point will result in different moving speed and moving distance. FIG. 1 is a schematic view of moving distance of a golf ball hit by a common type of golf putter. Referring to FIG. 1, under ideal situation, the middle section of hitting panel section hits a first golf ball 51, and then the first golf ball 51 moves a distance to reach a first stopping point 41. However, in the actual hitting, due to the performance of the player, if a second golf ball 52 or a third golf ball 53 is hit closer to either of the two sides of the hitting panel section 20 instead of a sweet point in a middle section, the second golf ball 52 or the third golf ball 53 changes in the moving direction and the moving distance compared with the first golf ball 51 and may eventually reach a second stopping point 42 or a third stopping point 43. Therefore, the fault tolerance is very small in the actual hitting.

Therefore, it is necessary to provide a golf putter head with higher fault tolerance and stability and a golf putter with the head.

SUMMARY OF THE TECHNOLOGY

An objective of the present disclosure is to provide a golf putter head with high fault tolerance and stability and a putter with the putter head.

According to the first aspect of the present disclosure, the disclosure provides a golf putter head which comprises a putter head, wherein a hitting face is provided on the putter head; a hitting unit is distributed on the hitting face, wherein the rigidity of the hitting unit is increased from a middle section outwardly to both sides along a width direction of the hitting face.

The hitting unit refers to protrusions, grooves or some other similar structures provided on the hitting face which are well known to those skilled in the art. In the meantime, a certain hitting unit can also form a certain texture on the hitting face and the hitting face is used to contact the golf ball. On the hitting face, the direction from the toe to the heel (or from the heel to toe) defines the direction of width of the hitting face, the rigidity of the portion of the hitting unit which is near the middle section of the hitting face is lower than the rigidity of the portion of the hitting unit which is far from the middle of the hitting face, and the different portions of the hitting unit or/and the hitting unit at different positions have a trend to gradually increase in rigidity from the middle to the both sides in the width direction of the hitting face. In addition, the rigidity distribution of the hitting unit can be specifically set according to the design of the golf putter head, the size and shape of the putter head, and the like. The end portion in the width direction of the hitting face (such as the toe portion and the heel portion) may be an area covered by the hitting unit, or may be an area not covered by the hitting unit. When the toe portion and the heel portion are areas that are not covered by the hitting unit, the rigidity of the toe portion is preferably higher than the rigidity of the hitting unit (or a portion thereof) which is near the toe portion. Similarly, the rigidity of the heel portion is preferably higher than the rigidity of the hitting unit (or a portion thereof) which is near the heel portion, which is, the rigidity of the hitting face is increased from the middle to both sides in the width direction of the hitting face.

According to the embodiment of the present disclosure, due to the difference in rigidity of the hitting face, when hitting the golf ball, the father away from the middle section of the hitting face, the larger momentum the golf ball achieved, the higher velocity the golf ball has, the less distance the golf ball loses during movement; the closer to the middle section of the hitting face, the greater distance the golf ball loses during movement. Since the difference in the moving distance of the golf ball after being hit by different portions is reduced, and the fault tolerance of the golf putter may be greatly improved, therefore the stability of putting may be improved.

Generally, a casing may be disposed on one side (e.g. the heel portion) of the putter head which can be coupled to the golf putter shaft to form a golf putter.

In addition, according to an embodiment of the present invention, the golf putter head may further have the following additional technical features:

- In some embodiments of the present disclosure, the hitting unit is disposed on panel connectors, and the panel connectors are fixedly coupled to the putter head.
- Advantageously, at least two panel connectors are sequentially coupled to the putter head.
- In some embodiments of the present disclosure, the hitting unit is arranged in an array on the hitting face.
- Advantageously, the hitting unit is arranged in an array of at least one of a linear array or an arc array.
- Advantageously, the array arrangement may be an array distributed along the width direction of the hitting face and perpendicular to each other. A single protrusion, depression or other structure of the array does not limit its size or specific shape, including but not limited to circles, triangles, rectangles, hexagons or other regular or irregular shapes.
- In some embodiments of the present disclosure, the hitting unit is made of at least one of an alloy or a plastic.
- Advantageously, the alloy is at least one of an iron alloy, an aluminum alloy, a copper alloy, or a titanium alloy.
- Advantageously, the iron alloy is at least one of 303 stainless steel, 304 stainless steel, 316 stainless steel, carbon steel S20C, carbon steel S25C, carbon steel S15C, carbon steel S45C, carbon steel 8620, or Carpenter steel.
- Advantageously, the alloy is a heat treated alloy. Specifically, the heat treatment may be performed by solution treatment and then quenching to change the rigidity of the alloy.
- The hitting unit has a trend to gradually increase in rigidity from the middle section outwardly to both sides (heel and tow portions) in the width direction of the hitting face, and the trend can be achieved by at least two ways, either alone or in combination. For example, in one embodiment, the first hitting unit made of different alloy materials with different rigidity is arranged on the hitting face in a certain rigidity order, wherein the rigidity increases from the middle to both sides (heel and toe portions); In a second embodiment, different heat treatment conditions may be applied to different portions of the hitting unit or the hitting unit to be disposed at different positions in order to achieve the rigidity gradually increasing from the middle to both sides (heel and toe portions).

According to a second aspect of the present disclosure, the disclosure provides a golf putter. The golf putter comprises a putter shaft and a putter head coupled to the putter shaft, wherein the putter head is the above-mentioned putter head. Specifically, the putter shaft can be coupled to the golf putter head by a casing provided on the golf putter head. Since the rigidity of the hitting unit is provided in a layer-wise manner, the difference in the moving distance of the golf ball after being hit by different portions is reduced, and the fault tolerance of the golf putter can be greatly improved, therefore the stability of putting can be improved.
