  An object of the present invention is to provide a golf tee having the advantages of the prior art and capable of solving the above problems.

  In order to achieve the above object, the present invention comprises a fixed member having a vertical direction and formed of a hard plastic material, and a movable member formed of a soft plastic material. A pedestal portion that is positioned, an insertion portion that extends sharply downward from the pedestal portion, and an extension portion that extends upward from the center portion of the pedestal portion, wherein the movable member is vertically To improve a golf tee that is formed in a cylindrical body that is slidably inserted and has a ball support portion that is divided into a plurality of strips at an upper end portion of the movable member, and a base portion that is in contact with and apart from the pedestal portion. It is in.

The features for the improvement are as follows.
The extending portion, said from a portion of the fixed member A as with the fixing member be formed as an integrally struts rigid, the strut is have a ball abutment surface at its upper end.
Said movable member, regulating means for the sliding range upward along the strut is provided between the fixed member and the movable member.
The restricting means includes a concave groove portion that extends upward from the pedestal portion on the opposed peripheral surface of the support column portion, and a protruding portion that is formed on the inner side opposite to the movable member and slidably fits in the concave groove portion. Has been.
The strut portion includes a large-diameter lower portion where the concave groove portion is formed, and a small-diameter upper portion connected to the large-diameter lower portion, and the ball contact surface is formed on the small-diameter upper portion.
The ball contact surface and the ball support portion are configured so that, when the base member and the base portion are in contact with each other, the ball contact surface is more than the ball support portion when the movable member is not slid upward. The relationship is located at the bottom.

  The present invention includes the following preferred embodiments.

The ball contact surface is formed in a concave curved surface downward, and a window hole is formed in an opposing peripheral surface in a required range upward from the vicinity of the base.

  According to the golf tee of the present invention, when the ball is supported by the movable member and the tee is impacted by the club head, the movable member slides upward along the column portion of the fixed member. Therefore, the impact is relieved or absorbed, the club head is not damaged, and it is possible to prevent the tee from coming off the ground and flying away to the illusion.

  Although the movable member is soft, the movable member is integrated with the fixed member and supported by the same hard column portion, so that the support state is stable, and the ball is immediately and stably and reliably supported. That is, it is possible to tee up correctly immediately.

  Furthermore, according to the embodiment of the present invention, the tee is composed of only two members, a fixed member and a movable member, which are integrally provided with a column portion, and its structure is simpler than the prior art, and is inexpensive and mass-produced. Excellent in properties.

  The best mode of the golf tee according to the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 and 2, the tee 10 has a vertical direction L, and includes a fixed member 11 formed from a hard plastic material and a movable member 12 formed from a soft plastic material.

  The fixing member 11 has a circular cross section, a pedestal portion 13 at the top, an insertion portion 14 into the ground that gradually becomes smaller in diameter downward from the pedestal portion 13 and has a sharpest bottom end, and the pedestal portion 13 And a support column 15 extending upward from the center of the upper surface. The support column 15 has a large-diameter lower portion 15a and a small-diameter upper portion 15b. A concave groove portion 16 (see FIG. 3) extending from the pedestal portion 13 to the vicinity of the upper end of the large diameter lower portion 15a is formed on the opposed peripheral surface of the large diameter lower portion 15a. A tipeg-like ball contact surface 17 that is bent downward is formed at the upper end of the small-diameter upper portion 15b.

  The movable member 12 is formed in a cylindrical body having a circular cross section, and a ball support portion 18 divided into a plurality of strips 18 a at the upper end portion, a base portion 19 having substantially the same diameter as the pedestal portion 13, and the base portion 19. A protruding portion 20 is formed on the inner side of the groove portion 16 so as to be slidable up and down. Furthermore, the window part 21 is formed in the opposing peripheral surface of the required range which goes upwards from the vicinity of the base part 19 (refer FIG. 4).

  For the tee-up, the ball support 18 supports a ball (not shown). In this state, the ball support portion 18 is flexible because the movable member 12 is formed of a soft plastic material, so that the strip 18a is pushed outward from the diameter of the movable member 12 by the weight of the ball.

  As is clear from the foregoing, the movable member 12 slides upward along the fixed member 11 between the concave groove portion 16 of the fixed member 11 and the protruding portion 20 of the movable member 12 that is slidably fitted in the groove 16. Restricting means M for the range to be configured is configured.

  As shown in FIGS. 6A and 6B, when the tee 10 is fitted to the outer periphery of the column portion 15 of the fixed member 11, these members are coupled to each other. In this state, the protruding portion 20 is fitted to the concave groove portion 16 so as to be slidable up and down, the base portion 19 contacts the pedestal portion 13, and the ball contact surface 17 is lower than the upper end of the ball support portion 18. (See FIG. 6A). Further, in this state, the window portion 21 and the concave groove portion 16 are in the same positional relationship. The tee 10 in such a state is in a form in which it is molded and provided to consumers, that is, in a non-use state.

  However, the movable member 12 moves upward with respect to the fixed member 11 by the tee shot. At this time, the movable member 12 slides upward by the up-and-down sliding restricting means of the movable member 12 composed of the concave groove portion 16 and the protruding portion 20, and the base portion 19 is separated from the pedestal portion 13 so that the ball abuts. The surface 17 is located further below the upper end of the ball support 18 (see FIG. 6B).

  In the embodiment in which the window 21 is formed on the movable member 12, the fixed member 11 and the movable member 12 coupled thereto can be molded by “integral molding” referred to in the plastic molding industry. As obvious to those skilled in the art, the window portion 21 functions as a guide portion for positioning a slide core that constitutes a part of the mold for molding. Therefore, the troublesome and costly operation of joining the fixed member 11 and the movable member 12 after each molding is not required.

  Referring to the tee-up operation of the tee 10 according to the present invention having the above-described configuration, as shown in FIG. 7, the player presses the ball B against the ball support portion 18 of the movable member 12 during the tee-up operation. 18 is pushed open to abut against the ball abutting surface 17 of the support column 15 of the fixing member 11, and when pressure is applied to the ball B toward the ground so as to push it down, the tee 10 passes through the ball B. It is smoothly and easily inserted into the ground. Incidentally, at this time, the pressure acts on the fixed member 11 linearly in the axial direction, and the movable member 12 does not buckle as well as the fixed member 11.
