Detailed Description

In the embodiments described below, the golf tee shown in fig. 1 to 7 includes not only an indispensable structure but also an alternative or preferable structure.

Referring to fig. 1 to 3, the golf tee 10 has an upward direction Y1, a downward direction Y2, and a circumferential direction R, and includes a fixed support rod 20 inserted into the ground, and a hollow cylindrical ball support post 30 rotatably connected to the fixed support rod 20 and on which a golf ball 40 is placed. The anchor strut 20 has a base end portion 21 in which a joint shaft portion 23 extending in a direction intersecting the central axis P is integrally formed, and a tapered tip end portion 22 having a smaller diameter than the base end portion 21. The fixing bar 20 is made of a hard plastic material, for example, a thermoplastic resin such as polyethylene and polypropylene, or a thermosetting resin such as an acrylic resin. In this specification, the state in which the golf tee 10 is extended means a state in which the fixed link 20 and the ball support post 30 are aligned in the upper direction Y1 and the lower direction Y2, and the state in which the golf tee 10 is folded means a state in which the fixed link 20 is rotated and moved into the ball support post 30.

The ball support post 30 has an upper end edge 30a, a lower end edge 30b, a bearing portion 31 having a receiving hole into which the joint shaft portion 23 of the fixing stay 20 is engaged, a stem 32 extending in the upward direction Y1 from the bearing portion 31, and a petal-shaped ball placement portion 33 located in the upward direction Y1 of the stem 32. The base end portion 21 of the fixed stay 20 is pivotally supported by the bearing portion 31, and the inner peripheral dimension of the lower end opening of the ball support column 30 through which the base end portion 21 passes is substantially the same as the outer peripheral dimension of the base end portion 21 and is in close contact with each other, so that the fixed stay 20 and the ball support column 30 are stably coupled. The ball mounting portion 33 is constituted by a plurality of support pieces 33a, and the plurality of support pieces 33a are arranged radially in a plan view so as to be separated from each other in the circumferential direction R. The ball support column 30 can be formed of a soft plastic material, for example, a thermoplastic resin such as a polyolefin resin, a polyurethane resin, or a polyamide resin, a synthetic rubber such as a silicone rubber or a urethane rubber, or a natural rubber. The concave finger-abutting portion 38 provided with the plurality of protrusions 37 is located on the front side of the

opposing wall portions

51 and 52 described later. Further, a plurality of concave finger rests 39 arranged separately in the upper direction Y1 and the lower direction Y2 are located on the back side of the stem 32.

The ball support post 30 also has a guide groove hole 36 extending from the upper end edge 30a to the lower end edge 30b on the outer peripheral surface. The guide groove hole 36 is formed between the

opposing wall portions

51 and 52, which are formed by a part of the outer peripheral edge, and which oppose each other in the circumferential direction R, and the guide groove hole 36 has a narrow width portion 36A extending from the lower end edge 30B in the upward direction Y1 and a wide width portion 36B extending from the vicinity of the upper end of the finger rest portion 38 to the upper end edge 30 a. The width dimension (dimension in the circumferential direction R) W1 of the narrow portion 36A is smaller than the diameter dimension of the proximal end portion 21 of the anchor strut 20, and the width dimension W2 of the wide portion 36B is the same as or slightly smaller than the diameter dimension of the distal end portion 22. In the illustrated example, the distal end of the support piece 33a constituting the ball mounting portion 33 has a shape inclined obliquely downward so that the ball 40 is stably mounted horizontally with respect to the ground. The shape is not limited to this shape as long as the same effects can be obtained. Further, the ball mounting portion 33 is formed of 5 support pieces 33a, but may be formed of 5 or less or 5 or more support pieces, or may be formed of concave portions that are continuous in the circumferential direction instead of the support pieces that are separated from each other, as long as the golf ball 40 can be stably mounted.

Referring to fig. 5 (a) to 5 (c), the fixed stay 20 of the golf tee 10 is rotatable about the joint shaft 23 engaged with the through hole (receiving hole) of the bearing portion 31 of the support post 30, and one example of an operation method thereof will be described below, in which first, a golfer grasps the ball support post 30 by pressing the thumb and the index finger of one hand against the finger-abutting

portions

38 and 39, and grasps the distal end portion 22 of the fixed stay 20 by pressing the other hand, and rotates the distal end portion 22 of the fixed stay 20 toward the ball support post 30. The

opposing wall portions

51 and 52 forming the outer peripheral surface of the guide groove hole 36 are elastically expanded in the circumferential direction R while the fixing stay 20 is rotated, and the separation dimension thereof gradually increases. Referring to fig. 5 (b), in a state where the fixing stay 20 is rotated by 90 degrees with respect to the ball support post 30, the separation dimension of the narrow portion 36A of the guide groove hole 36 is maximized, and the entire fixing stay 20 passes through the guide groove hole 36 by further rotating the fixing stay 20 in a state where the base end portion 21 is held in pressure contact with the

opposing wall portions

51 and 52. After the fixing stays 20 pass through the guide slots 36, the expanded

opposite wall portions

51 and 52 are elastically restored and restored to the original state.

Referring to fig. 5 (c), the fixing stay 20 is rotated 180 degrees from the position where the support column 30 is connected to the fixing stay 20 in the upward direction Y1 on the fixing stay 20 and is completely positioned in the internal space 50 of the support column 30, and the distal end portion 22 of the fixing stay 20 is in a state of facing the upward direction Y1 so as to be surrounded by the support piece 33a of the ball mounting portion 33. By rotating the fixing stay 20 and locating it completely in the internal space 50 of the support column 30 in this way, the golf tee 10 can be made compact and excellent in stowability and portability. Therefore, the player can directly store the golf tee in the pocket of the clothes in a state of folding the golf tee. Further, when the golf tee 10 is brought into the original extended state, the golfer operates: while the ball support column 30 is held by one hand, the distal end portion 22 of the anchor strut 20 located in the internal space 50 is held by the other hand, the distal end portion 22 of the anchor strut 20 is displaced toward the guide groove hole 36, and the distal end portion 22 of the anchor strut 20 is rotated so as to pass through the guide groove hole 36 while the

opposing wall portions

51 and 52 are expanded. Thus, the golf tee 10 can be simply and rapidly operated to switch between the folded state and the extended state by the simple structure.

Referring to fig. 6, as shown in fig. 5 (c), in a state where the fixed stay 20 is completely located in the internal space 50 of the support column 30, a part of the distal end portion 22 is located above the upper end edge 30a of the ball support column 30. In this way, since the tip portion 22 protrudes in the upward direction Y1 beyond the upper edge 30a in the folded state, the tip portion 22 is easily pinched when the ball support column 30 is extended, and the guide groove hole 36 can be expanded and the anchor strut 20 can be displaced outward of the ball support column 30 by, for example, pushing the thumb against the tip portion 22 and moving the tip portion 22 toward the guide groove hole 36 while maintaining this state. In this case, since the width W2 of the wide portion 36B is substantially the same as the outer diameter of the distal end portion 22 of the anchor strut 20 or slightly smaller than the outer diameter of the distal end portion 22 of the anchor strut 20, the distal end portion 22 can pass through the wide portion 36B without receiving a large resistance, and a smooth operation can be performed.

Referring to fig. 7, when the golf ball 40 placed on the ball placing part 33 of the golf tee 10 is struck, a force in the swing direction and a force to rotate the ball support post 30 act on the golf tee 10 by the impact. The golf tee 10 is inserted into the ground 60 so that the guide groove hole 36 is positioned on the opposite side of the striking surface of the golf ball 40, and at the moment of striking a ball, a force for rotating the support column 30 acts, the

opposing wall portions

51 and 52 on the bearing portion 31 side are expanded by the base end portion 22 of the fixed stay 20, the base end portion 22 is positioned in the narrow portion 36A in a state of being pressed against the

opposing wall portions

51 and 52, and the ball support column 30 is inclined with respect to the ground 60. Thus, since the ball support columns 30 can be bent to absorb the impact of the impact, the golf tee 10 can be prevented from being separated from the floor 60.

As described above, since the width W1 of the narrow portion 36A of the guide groove hole 36 is smaller than the outer diameter of the fixed stay 20, resistance is generated when passing through the guide groove hole 36, and a relatively strong force is required to move the ball support post 30 and expand the narrow portion 36A. Therefore, for example, even if the face of the golf club hits the ball support post 30 of the golf tee 10 at the moment of a shot during a golf shot and the guide groove hole 36 is slightly expanded by the fixing stay 20, the state of rotation of the ball support post 30 can be maintained, and thus the golf tee 10 can be prevented from coming off the ground.

Unless otherwise specifically indicated, the components constituting the golf tee 10 may be made of any of various known materials that are generally used in the art, without limitation, in addition to the materials described herein.

The structure of the golf tee of the present invention can be organized as follows.

The golf tee has an upper direction and a lower direction, and includes a hollow support post having a ball receiving portion, and a fixed stay inserted into the ground, the support post having a guide groove hole extending in the upper direction and the lower direction on an outer peripheral surface thereof, the fixed stay being rotatably connected to the support post, the fixed stay being displaceable from a position where it is connected to the support post in the lower direction to an inside and an outside of the support post via the guide groove hole.

The present invention includes embodiments that can be adopted alone or in combination.

(1) The fixing stay has a tip end portion and a base end portion where a joint shaft portion is located, the support post has a stem portion extending downward from the ball mounting portion and a bearing portion located below the stem portion, and the joint shaft portion is engaged with a through hole located in the bearing portion.

(2) The guide slot has a narrow portion extending upward from a lower end edge of the support column and a wide portion extending upward from the narrow portion, the narrow portion having a width dimension smaller than an outer diameter dimension of the base end portion of the fixed stay, and the fixed stay passes through the guide slot by elastically deforming a portion of an outer peripheral surface of the support column and an opposing wall portion forming the guide slot.

(3) The distal end portion of the fixed stay protrudes above the ball placement portion in a state where the fixed stay is positioned inside the support column by rotating the fixed stay.

(4) The ball mounting portion is formed of a plurality of support pieces and is radial in plan view.
