Description

本発明は、ヘッド本体のフェース部にフェースインサートを装着したパターヘッドに関する。   The present invention relates to a putter head having a face insert attached to a face portion of a head body.

従来、ヘッド本体のフェース部に、ヘッド本体とは別の材料からなるフェースインサートを装着したパターヘッドが提案されている。例えば、特許文献１には、ヘッド本体のフェース部に、ゴム弾性体層と焼結金属層とフッ素樹脂層との一体積層構造のフェースインサートを装着したパターヘッドが記載されている。また、特許文献２には、ヘッド本体のフェース部に、ヘッドのスイートスポット近傍側から周縁側に近づくにつれて肉厚が増大する弾性体製フェースインサートを装着したパターヘッドが記載されている。   Conventionally, there has been proposed a putter head in which a face insert made of a material different from that of the head main body is mounted on the face portion of the head main body. For example, Patent Document 1 describes a putter head in which a face insert having an integrally laminated structure of a rubber elastic body layer, a sintered metal layer, and a fluororesin layer is mounted on a face portion of a head body. Patent Document 2 describes a putter head in which an elastic face insert whose thickness increases as it approaches the peripheral side from the vicinity of the sweet spot of the head on the face portion of the head body is described.

前述したヘッド本体にフェースインサートを装着したパターヘッドは、通常、フェースインサートによってボールをヒットしたときの打感を柔らかくすることを目的としている。   The above-described putter head in which a face insert is mounted on the head body is usually intended to soften the hit feeling when a ball is hit with the face insert.

しかし、従来のヘッド本体にフェースインサートを装着したパターヘッドでは、フェースインサートによって打感が柔らかくなる一方、打音が鈍く（低く）なり、パットの距離感をつかみにくくなることがあった。   However, in a putter head in which a face insert is attached to a conventional head body, the hit feeling is softened by the face insert, but the hitting sound becomes dull (lower), and it may be difficult to grasp the sense of distance of the pad.

本発明は、前述した事情に鑑みてなされたもので、ヘッド本体にフェースインサートを装着したパターヘッドであって、ボールをヒットしたときの打感が柔らかいとともに、打音が硬く（高く）、したがってパットの距離感をつかみやすいパターヘッドを提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and is a putter head in which a face insert is mounted on a head body, and the hitting sound when a ball is hit is soft and the hitting sound is hard (high). The object is to provide a putter head that easily grasps the distance of the putt.

本発明は、前記目的を達成するため、ヘッド本体のフェース部にフェースインサートを装着したパターヘッドにおいて、前記フェースインサートは、打面を形成する高硬度部分と、前記高硬度部分に接合された前記高硬度部分よりも硬度が低い低硬度部分とからなることを特徴とするパターヘッドを提供する。   In order to achieve the above object, the present invention provides a putter head in which a face insert is attached to a face portion of a head body, wherein the face insert includes a high-hardness portion forming a striking surface and the high-hardness portion joined to the high-hardness portion. Provided is a putter head comprising a low hardness portion having a lower hardness than a high hardness portion.

本発明のパターヘッドでは、打面（ゴルフボールを直接打撃する面）を形成する高硬度部分の硬度が高いため、この高硬度部分によって硬い（高い）打音を得ることができ、したがってパットの距離感をつかみやすい。また、フェースインサートの高硬度部分以外の部分を形成する低硬度部分の硬度が高硬度部分よりも低いため、この低硬度部分によって柔らかい打感を得ることができる。   In the putter head of the present invention, since the hardness of the high hardness portion that forms the striking surface (the surface that directly hits the golf ball) is high, a hard (high) striking sound can be obtained by this high hardness portion. It is easy to get a sense of distance. Further, since the hardness of the low hardness portion forming the portion other than the high hardness portion of the face insert is lower than that of the high hardness portion, a soft feel can be obtained by this low hardness portion.

以下、本発明につきさらに詳しく説明する。本発明において、ヘッド本体の材質としては、例えば、ステンレススチール、アルミニウム、アルミニウム合金、真鍮、銅、チタニウム合金、亜鉛、炭素繊維強化樹脂等を挙げることができるが、これらに限定されるものではない。   Hereinafter, the present invention will be described in more detail. In the present invention, examples of the material of the head body include, but are not limited to, stainless steel, aluminum, aluminum alloy, brass, copper, titanium alloy, zinc, and carbon fiber reinforced resin. .

また、フェースインサートの高硬度部分および低硬度部分の材質としては、例えば、アイオノマー樹脂、ウレタン樹脂、ウレタン系エラストマー、ポリエステル系エラストマー等の合成樹脂類、スチレンブタジエンラバー、ブタジエンゴム等のゴム類などを挙げることができるが、これらに限定されるものではない。フェースインサートの高硬度部分および低硬度部分の材質として特に好ましいのは、ウレタン系エラストマー、ポリエステル系エラストマー等のエラストマーおよびウレタン樹脂である。   In addition, examples of the material of the high hardness portion and the low hardness portion of the face insert include synthetic resins such as ionomer resin, urethane resin, urethane elastomer, and polyester elastomer, and rubbers such as styrene butadiene rubber and butadiene rubber. It can be mentioned, but is not limited to these. Particularly preferable materials for the high hardness portion and the low hardness portion of the face insert are elastomers such as urethane elastomers and polyester elastomers, and urethane resins.

本発明では、高硬度部分のショアＤ硬度を３０以上、より好ましくは３５〜１００、低硬度部分のショアＤ硬度を１０以上、より好ましく１５〜６０、高硬度部分のショアＤ硬度と低硬度部分のショアＤ硬度との差を５以上、より好ましくは１０〜８５とする。高硬度部分のショアＤ硬度が３０未満であると、硬い打音が得られないことがある。低硬度部分のショアＤ硬度が１０未満であると、柔らかい打感が得られないことがある。高硬度部分のショアＤ硬度と低硬度部分のショアＤ硬度との差が５未満であると、打感を柔らかくし、打音を硬くするという本発明の効果が得られないことがある。   In the present invention, the Shore D hardness of the high hardness portion is 30 or more, more preferably 35 to 100, the Shore D hardness of the low hardness portion is 10 or more, more preferably 15 to 60, the Shore D hardness and the low hardness portion of the high hardness portion. The difference from the Shore D hardness is 5 or more, more preferably 10 to 85. If the Shore D hardness of the high hardness portion is less than 30, hard hitting sound may not be obtained. If the Shore D hardness of the low hardness portion is less than 10, a soft feel may not be obtained. When the difference between the Shore D hardness of the high hardness portion and the Shore D hardness of the low hardness portion is less than 5, the effects of the present invention that soften the hit feeling and harden the hitting sound may not be obtained.

本発明では、高硬度部分および低硬度部分の一方または両方を多層構造とすることができる。高硬度部分のみを多層構造とする場合、高硬度部分のうちのゴルフボールと接する最外層のショアＤ硬度、および上記最外層と低硬度部分との硬度差を前述した値とする。低硬度部分のみを多層構造とする場合、低硬度部分のうちのヘッド本体に最も近い最内層のショアＤ硬度、および上記最内層と高硬度部分との硬度差を前述した値とする。高硬度部分および低硬度部分の両方を多層構造とする場合、高硬度部分のうちのゴルフボールと接する最外層のショアＤ硬度、低硬度部分のうちのヘッド本体に最も近い最内層のショアＤ硬度、および上記高硬度部分の最外層と低硬度部分の最内層との硬度差を前述した値とする。   In the present invention, one or both of the high hardness portion and the low hardness portion can have a multilayer structure. When only the high hardness portion has a multi-layer structure, the Shore D hardness of the outermost layer in contact with the golf ball in the high hardness portion and the hardness difference between the outermost layer and the low hardness portion are the values described above. When only the low hardness portion has a multi-layer structure, the Shore D hardness of the innermost layer closest to the head main body in the low hardness portion and the hardness difference between the innermost layer and the high hardness portion are set to the values described above. When both the high hardness portion and the low hardness portion have a multilayer structure, the outermost layer Shore D hardness in contact with the golf ball in the high hardness portion, and the innermost layer Shore D hardness closest to the head body in the low hardness portion The difference in hardness between the outermost layer of the high hardness portion and the innermost layer of the low hardness portion is the value described above.
