Title:
GOLF TEE
Document Type and Number:
WIPO Patent Application WO/2013/121576
Kind Code:
A1
Abstract:
The resistance at the time a golf ball is hit is decreased, the drawing of an image of a direction in which the golf ball is hit is facilitated, and the accurate positioning of a golf player is facilitated with respect to a target direction by allowing a support shaft to be thrust, with the golf ball being mounted thereon, in a state inclined toward the target direction. The present invention includes a ball seat portion (14) on which a golf ball (12) is placed, and a rod-shaped support shaft (16) formed downward from the ball seat portion (14). The support shaft (16) includes a projection (16a) that projects sideward. The ball seat portion (14) and the support shaft (16) are formed in surface symmetry with respect to a plane including a tip end of the projection (16a) and a central axis of the support shaft (16). The central axis of the support shaft (16) and a virtual plane including a contact portion which comes into contact with the golf ball (12) when the golf ball (12) is mounted above the ball seat portion (14) form an obtuse angle on one side of the axis in the plane, and an acute angle on the other side of the axis. The projection (16a) projects on the side at which the obtuse angle is formed.
