This embodiment is provided to more completely explain the present invention to those of ordinary skill in the art.

따라서, 도면에서 표현한 구성요소의 형상 등은 더욱 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 각 도면에서 동일한 구성은 동일한 참조부호로 도시한 경우가 있음을 유의하여야 한다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기술의 기능 및 구성에 관한 상세한 설명은 생략될 수 있다.Accordingly, the shape of the components expressed in the drawings may be exaggerated in order to emphasize a clearer description. It should be noted that the same components in each drawing are sometimes illustrated with the same reference numerals. In addition, detailed descriptions of functions and configurations of known technologies that may unnecessarily obscure the gist of the present invention may be omitted.

먼저, 본 발명의 일 실시 예에 따른 분할형 구조를 이루는 골프클럽용 페룰의 구성을 도 2 내지 도 5를 통해 살펴보면 다음과 같다.First, a configuration of a ferrule for a golf club having a divided structure according to an embodiment of the present invention will be described with reference to FIGS. 2 to 5 as follows.

본 실시 예에서의 골프클럽용 페룰(20)은 원통형 구조를 이루어서 골프클럽의 헤드(10)와 샤프트(30) 연결부에 결합이 이루어지게 되는데, 이때 페룰(20)은 2개의 페룰 조립체(21)로 분리된 분할형 구조를 이루고 있으며, 상기 2개의 페룰 조립체(21) 상호 간에는 다수의 결합돌기(22)와 결합홈(23)에 의한 착탈이 가능하게 된다.The ferrule 20 for a golf club in this embodiment has a cylindrical structure so that it is coupled to the connection portion between the head 10 and the shaft 30 of the golf club, in this case, the ferrule 20 includes two ferrule assemblies 21 . It has a divided structure separated by a ferrule assembly 21, and it is possible to attach and detach the two ferrule assemblies 21 with each other by a plurality of coupling protrusions 22 and coupling grooves 23.

즉, 페룰 조립체(21)는 2개로 나뉘어진 2분할형 구조를 이루고 있으며, 각각의 페룰 조립체(21) 양측에는 결합돌기(22) 및 결합홈(23)이 대칭 형태로 구비된다.That is, the ferrule assembly 21 has a two-part structure divided into two, and coupling protrusions 22 and coupling grooves 23 are provided on both sides of each ferrule assembly 21 in a symmetrical form.

또한, 결합돌기(22)는 결합홈(23)과의 결합상태가 안정적으로 유지될 수 있도록 일측에 쐐기부(22a)가 형성되고, 결합돌기(22)의 일측에는 쐐기부(22a)의 탄성 변형력 증대를 위한 완충 홈부(22b)가 형성된 것을 도 5의 부분 확대도를 통해 확인할 수 있다.In addition, a wedge portion 22a is formed on one side of the engaging protrusion 22 so that the engaging state with the engaging groove 23 can be stably maintained, and the elasticity of the wedge 22a is formed on one side of the engaging projection 22 . It can be seen from the partially enlarged view of FIG. 5 that the buffer groove portion 22b for increasing the deformation force is formed.

도면 중 미설명 부호 24는 샤프트가 끼워지는 샤프트 통공을 나타낸다.Reference numeral 24 in the drawings denotes a shaft through hole into which the shaft is inserted.

이와 같은 구성을 이루는 본 발명 분할형 페룰 구조체의 사용에 따른 작용효과를 살펴보기로 한다.Let's take a look at the effects of the use of the split ferrule structure of the present invention having such a configuration.

본 발명에서의 페룰(20)은 골프 헤드(10)와 샤프트(30) 연결부위에서 샤프트(30)에 끼워지는 형태로 조립이 이루어지게 되는데, 사용 중 강한 타격력으로 인해 파손 내지는 손상이 발생된 경우 수리 또는 교체를 위해 샤프트(30)로 부터 분리가 이루어지게 된다.The ferrule 20 in the present invention is assembled in the form of being fitted to the shaft 30 at the connection portion between the golf head 10 and the shaft 30, and repairs when damage or damage occurs due to a strong striking force during use. Alternatively, separation from the shaft 30 is made for replacement.

즉, 이때에는 결합돌기(22)와 결합홈(23)에 의해 상호 조립된 상태를 이루는 페룰 조립체(21)를 분해함으로써 골프클럽으로부터 분리가 가능하며, 분리 후 파손 부위를 수리 내지는 교체한 후 다시 골프클럽에 조립 결합이 이루어질 수 있게 된다.That is, at this time, it is possible to separate from the golf club by disassembling the ferrule assembly 21 that forms the mutually assembled state by the coupling protrusion 22 and the coupling groove 23, and after the separation, the damaged part is repaired or replaced again. Assembled coupling to the golf club can be made.

특히, 결합돌기(22)에는 쐐기부(22a) 및 완충 홈부(22b)가 형성되어 있기 때문에 결합홈(23)로 부터 이탈이 용이하게 이루어짐과 함께 결합홈(23)과 안정적인 체결상태가 유지될 수 있게 된다.In particular, since the wedge portion 22a and the buffer groove portion 22b are formed in the engaging projection 22, it is easily separated from the engaging groove 23 and a stable fastening state with the engaging groove 23 is maintained. be able to

따라서 본 발명의 골프클럽용 페룰은, 다수개로 분할된 조립형 구조를 이루도록 하여 부품의 수리 또는 교체를 위한 골프클럽으로부터의 분리 및 조립이 보다 신속하고 용이하게 이루어질 수 있는 효과를 나타낸다.Therefore, the ferrule for a golf club of the present invention exhibits the effect that the assembly type structure divided into a plurality of pieces can be formed so that the separation and assembly from the golf club for repair or replacement of parts can be made more quickly and easily.
