Abstract
Disclosed is a golf tee including a main body having an upper seat on which a golf ball is supported; an insertion pin having a lower pointed part; and a connection pin connecting the insertion pin and the main body, the connection pin including an upper integral-type head part and a body part extending from the head part and having a lower screw section on a lower end thereof and around which a spring is integrally fitted, the insertion pin having an elongated screw hole extending from an upper central portion thereof such that the screw part of the connection pin is screwed therethrough.
Claims12
A golf tee comprising:
- a main body having an upper seat on which a golf ball is supported;
- an insertion pin having a lower pointed part;
- and
- a connection pin connecting the insertion pin and the main body,
- the connection pin including an upper integral-type head part and a body part extending from the head part and having a lower screw section on a lower end thereof and around which a spring is integrally fitted,
- the insertion pin having an elongated screw hole extending from an upper central portion thereof such that the screw part of the connection pin is screwed therethrough,
- wherein the main body is provided on a lower end thereof with a coupling groove, and the insertion pin is provided on an upper end thereof with a protrusion to be inserted into the coupling groove, wherein the coupling groove and the protrusion have a pair of male-female engaging steps, and
- wherein the coupling groove and the protrusion have a pair of male-female screw parts.
A method of manufacturing a golf tee comprising a hollow main body having, on an inner circumference, a step part below which a coupling groove is formed, and an insertion pin assembled with the main body and having an upper protrusion, through which an elongated screw hole vertically extends from an upper central portion of the upper protrusion, and a lower pointed portion, the method comprising:
- a stage (S10) of providing an elastic connection pin having an upper large-diameter head part and a body part extending from the head part and having a screw section on a lower portion thereof and around which a spring is integrally coupled to the head part;
- a stage (S20) of pushing the elastic connection pin, in which the spring is integrally coupled to the head part, down into the main body such that the spring is engaged against the step part of the main body and the screw section of the connection pin protrudes out of a lower portion of the main body;
- and
- a stage (S30) of screwing the screw section of the connection pin protruding out of the lower portion of the main body through the screw hole of the insertion pin so as to connect the connection pin and the insertion pin,
- wherein
- the method further comprises a stage of, after the stage of (S30) coupling the upper protrusion of the insertion pin into the coupling groove of the main body,
- the coupling groove and the upper protrusion are coupled using a engaging step and an engaging groove formed on the coupling groove and the upper protrusion, and
- the coupling groove and the upper protrusion are coupled using internal and external screw parts formed on the coupling groove and the upper protrusion.
