[0008] Exemplary embodiments of the present disclosure will now be described with reference to the drawings. First Embodiment 1. Configuration of Golf Tee 1 The configuration of golf tee 1 will be described with reference to Figs. 1 to 4. Golf tee 1 includes head 3 and shaft 5. As shown in Figs. 3 and 4, the direction from tip 5a of shaft 5 toward head 3 along the axial direction of shaft 5 is defined as upward direction U. The opposite direction is defined as downward direction D. Tip 5a is the part of shaft 5 on the opposite side to head 3. Direction A in Fig. 2 is perpendicular to upward direction U and downward direction D, and perpendicular to flat surface 5d described later. Direction B in Fig. 2 is perpendicular to upward direction U, downward direction D, and direction A.

[0009] As shown in Figures 1, 3 and 4, head 3 has a cone-like shape with inner and outer diameters increasing in the upward direction U. As shown in Figure 2, upper end 3a of head 3 in the upward direction U is a circular portion corresponding to the upper end of the cone. The outer diameter of upper end 3a is smaller than the diameter of golf ball 7. The outer diameter of upper end 3a is, for example, 17 mm or more and 23 mm or less. Golf ball 7 can be placed on upper end 3a. Upper end 3a corresponds to the placement surface.

[0010] As shown in Figs. 1 and 2, a plurality of protrusions 10 are arranged on the upper end 3a. Each of the plurality of protrusions 10 protrudes in the upward direction U. The plurality of protrusions 10 are lined up at regular intervals in the circumferential direction of the upper end 3a. The shape, size, and height of the plurality of protrusions 10 are, for example, equal to each other. When viewed from the upward direction U, the shape of each of the protrusions 10 is, for example, circular. When viewed from the direction U, the diameter of the protrusions 10 is, for example, 0.5 mm or more and 1.5 mm or less, and is preferably 1 mm.

[0011] The number of the protrusions 10 is, for example, 4 to 10, and preferably 6 to 8. For example, it is preferable that the outer diameter of the upper end portion 3a is 20 mm and the number of the protrusions 10 is 8.

[0012] As shown in Figures 1, 3 and 4, the shaft 5 is connected to the head 3. The basic shape of the shaft 5 is rod-like. The shaft 5 extends in the downward direction D from a lower end 3b, which is the end of the head 3 on the downward direction D side. The lower end 3b is a portion that corresponds to the bottom of the mortar.

[0013] The shaft portion 5 has a step portion 5b near the tip 5a. In the upward direction U and downward direction D, the distance from the step portion 5b to the tip 5a is 1 / 5 or less, and preferably 1 / 10 or less, of the length of the shaft portion 5.

[0014] The step portion 5b is composed of a downward portion 11, an intermediate portion 12, and an upward portion 13. The downward portion 11 is adjacent to the intermediate portion 12 and is located on the downward direction D side of the intermediate portion 12. The upward portion 13 is adjacent to the intermediate portion 12 and is located on the upward direction U side of the intermediate portion 12.

[0015] The downward portion 11 protrudes further toward the outer periphery of the shaft portion 5 than the upward portion 13. The middle portion 12 is a portion that connects the downward portion 11 and the upward portion 13. The stepped portion 5b has a stepped shape that protrudes toward the outer periphery of the shaft portion 5 on the downward direction D side (i.e., the side of the tip 5a).

[0016] For example, the intermediate portion 12 is a portion that protrudes more toward the outer periphery of the shaft portion 5 as it approaches the downward portion 11. For example, the downward portion 11 and the upward portion 13 are portions in which the change in the outer diameter of the shaft portion 5 is smaller when moving in the downward direction D than the intermediate portion 12. The angle formed between the downward portion 11 and the intermediate portion 12 may be any of an acute angle, a right angle, and an obtuse angle. The angle formed between the upward portion 13 and the intermediate portion 12 may be any of an acute angle, a right angle, and an obtuse angle. The surface of the intermediate portion 12 may be a flat surface or a curved surface.

[0017] As shown in Fig. 4, the shaft portion 5 has two step portions 5b. The two step portions 5b are located symmetrically with respect to the central axis of the shaft portion 5. As shown in Fig. 3, of the side surface 5c of the shaft portion 5, no step is provided in an intermediate portion 15 between the two step portions 5b in the circumferential direction of the shaft portion 5.

[0018] As shown in Figs. 1, 3 and 4, the side surface 5c includes a flat surface 5d extending along the axial direction of the shaft portion 5. The flat surface 5d is a plane. The shaft portion 5 has two flat surfaces 5d. The two flat surfaces 5d are located symmetrically with respect to the central axis of the shaft portion 5. The shape of the portion of the side surface 5c excluding the flat surfaces 5d is an arc shape when viewed from a viewpoint in the downward direction D.

[0019] The step portion 5b and the flat surface 5d are aligned in the axial direction of the shaft portion 5. The flat surface 5d extends from a portion of the shaft portion 5 adjacent to the head 3 to the step portion 5b. For example, the upward portion 13 is a portion of the flat surface 5d on the downward direction D side. The golf tee 1 is made of, for example, resin. The golf tee 1 can be manufactured, for example, by using a mold.

[0020] 2.How to use Golf Tee 1 Golf tee 1 can be used, for example, as follows: As shown in Fig. 5A, a user inserts a part of shaft 5, including tip 5a, into ground 101. At this time, step portion 5b is buried in ground 101. The axial direction of shaft 5 may coincide with the vertical direction or may be inclined relative to the vertical direction.

[0021] Next, the user places the golf ball 7 on the upper end portion 3a. The golf ball 7 comes into contact with the upper end portion 3a. The golf ball 7 also comes into contact with the multiple protrusions 10. Next, as shown in Figures 5B and 5C, the user hits the golf ball 7 placed on the upper end portion 3a with a driver 9. 3. Effects of Golf Tee 1 (1A) The shaft portion 5 has a step portion 5b. When the golf tee 1 is used, the step portion 5b is buried in the ground 101 as shown in Fig. 5A. Since the step portion 5b is buried in the ground 101, there is a large resistance when the golf tee 1 is pulled out from the ground 101. Therefore, when a user hits a golf ball 7 placed on the golf tee 1 as shown in Figs. 5B and 5C, even if a force is applied to the golf tee 1 in a direction to pull it out of the ground 101, the golf tee 1 is unlikely to come out of the ground 101 and is unlikely to fly.

[0022] (1B) The golf tee 1 has a flat surface 5d. As a result, when a user hits a golf ball 7 placed on the golf tee 1, the direction in which the golf tee 1 flies is likely to be a fixed direction. As a result, it becomes easier to find the golf tee 1 after hitting the golf ball 7.

[0023] (1C) Golf tee 1 has an array of multiple protrusions 10 on upper end 3a. Therefore, when golf ball 7 is placed on upper end 3a, golf ball 7 is stabilized. (1D) The step portion 5b and the flat surface 5d are aligned in the axial direction of the shaft portion 5. Therefore, it is easy to form the step portion 5b and the flat surface 5d.

[0024] (1E) The flat surface 5d extends from the portion of the shaft 5 adjacent to the head 3 to the step portion 5b. Therefore, the effect of (1B) above is more pronounced.

[0025] <Other embodiments> Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be implemented in various modified forms.

[0026] (1) The step portion 5b may be provided continuously around the entire circumference of the shaft portion 5. The number of step portions 5b may be other than 2, and may be, for example, 1, 3, 4, 5, etc. A plurality of step portions 5b may be lined up along the axial direction of the shaft portion 5. (2) The step portion 5b and the flat surface 5d do not have to be aligned in the axial direction of the shaft portion 5.

[0027] (3) The function of one component in each of the above embodiments may be shared by multiple components, or the functions of multiple components may be performed by one component. Also, part of the configuration of each of the above embodiments may be omitted. Also, at least part of the configuration of each of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.

[0028] (4) In addition to the golf tee 1 described above, the present disclosure can be realized in various forms, such as a system including the golf tee 1 as a component, a method for manufacturing the golf tee 1, etc. [Explanation of symbols]
