Description

The present invention relates to a golf practice tool for tee shots and a mat for tee shot practice. More particularly, the present invention relates to a tee shot practice tool as an alternative to a golf ball and a tee shot practice mat for using the same.

When practicing golf tee shots, using a real golf ball requires a large practice field. For this reason, the idea which practiced a tee shot simply has been made conventionally. For example, a method of practicing using a net cage for golf practice is disclosed (see Patent Document 1). Since this method can tee shot a real golf ball, you can practice with a sense of reality.

Further, instead of using a real golf ball, a golf practice tool for a tee shot made of a soft rubber ring having a cylindrical shape is disclosed (see Patent Document 2). This method eliminates the need to use a net cage because the tee-shot golf practice tool has a small flight distance, making it easier to practice tee shots than using the golf practice net cage described above. is there.
JP 2004-187833 A Utility Model Registration No. 3082435

However, the method of practicing using the golf practice net cage described above requires a considerable amount of site for net cage installation, and the trajectory of the shot ball is clear because the flight distance is limited. Not. For this reason, it is not easy to determine whether the shot ball is a hook ball or a slice ball, and it is not possible to confirm or correct the shot form.

In addition, when using the above-mentioned cylindrical and ring-shaped soft rubber tee shot golf practice tool, the tee head is very small (about 10 mm) and has a circular recess. It is difficult to stably place a cylindrical tee shot golf practice tool on a golf tee in a horizontally placed state. Also, even if a shot is taken in this horizontal position, slice rotation or hook rotation does not occur, so it cannot be judged whether the face of the golf club is correctly shooting this. Furthermore, it can be said that it is impossible to place this vertically on a golf tee.

Therefore, in order to solve the above-mentioned drawbacks, the present inventor can correct the shot form by confirming that the trajectory after the shot is a slice shot or a hook shot, and for a tee shot that emits a refreshing hitting sound. Provide golf practice equipment and tee shot practice mats.

The present invention is as follows.
1. A golf practice tool for tee shots that substitutes for a golf ball, wherein the golf practice tool for tee shots is a vertically long circular cylinder, the material of which is selected from the group of flexible paper, resin, elastomer, and rubber Consisting of at least one selected,
The outer diameter is a golf practice tool for tee shots having an outer diameter of 5 mm to 40 mm, a height of 40 mm to 100 mm, and a wall thickness of 0.05 mm to 0.50 mm. The golf practice tool for tee shot, which is a vertically long circular cylinder, is installed vertically and shot with a golf club driver or golf spoon. Thereby, depending on the angle at which the golf club face hits, the hook or slice of the tee shot golf practice tool rotates.
2. The golf practice tool for tee shots, wherein the material is one selected from the group of paper and paper coated with resin.
3. A golf practice tool for tee shot having dimples on the outer peripheral surface of the circular cylinder.
4). Furthermore, a tee clamping part is provided inside, and the tee clamping part is (A) a truncated cone shape of an internal cavity,
(B) The bottom portion is in contact with the inner peripheral surface of the circular cylindrical bottom portion,
(C) The material is at least one selected from the group of flexible paper, resin elastomer, and rubber. (D) A tee having a plurality of radial slits in plan view from the top to the bottom. Golf practice tool for shots.
5). A tee shot practice mat comprising an artificial turf layer and a shock absorbing layer, the artificial turf layer and the shock absorbing layer having through holes having a regular polygon in plan view for inserting the golf practice tool.

The golf practice tool for tee shot according to the present invention is a vertically long cylinder, and is shot with a driver or the like in a vertically placed state. For this reason, depending on the shot, slice rotation or hook rotation occurs in the golf practice tool for tee shots. For this reason, it is possible to judge a hook shot or a slice shot, and it is possible to easily check one's hitting form. In addition, since the golf practice tool for tee shot is a flexible circular cylinder, a sharp increase in air pressure in the cylinder is released from the upper end and / or the lower end of the cylinder due to the impact of the shot, so that it is refreshing. Sounds can be generated to have the same feeling as when a real golf ball is shot. Further, the golf practice tool for tee shots of the present invention is light in weight, so there is very little danger due to shots.
Moreover, when the material of the golf practice tool for tee shot is one selected from the group of flexible paper and paper coated with resin, it can be produced inexpensively and easily.
Furthermore, since the golf practice tool for tee shots of the present invention has dimples on the outer peripheral surface of the circular cylinder, the trajectory can be determined more clearly by slicing or rotating the shot.
In addition, when the golf tee holding portion is provided inside the circular cylinder, it is easy to tee up any shape golf tee, and this holding portion includes a slit, so that teeing is further facilitated.
In another golf practice mat of the present invention, the golf practice tool for tee shot can be easily placed on the mat in a vertical position.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to these drawings. In the present invention, a golf tee shot is used instead of a real golf ball for practice. FIG. 1 is a perspective view of a golf practice tool for tee shot according to the present invention. The tee shot golf practice tool 1 (hereinafter also simply referred to as “golf practice tool”) has a vertically long cylindrical shape. “Longitudinal” means that the outer diameter W1 of the golf practice tool 1 is smaller than the standing dimension H1. The golf practice tool 1 of the present application is used in a vertically placed state (see FIGS. 3, 4, 5, 8, and 9), and a cylindrical outer peripheral surface 11 is shot with a golf club driver or spoon.

This golf practice tool 1 is suitable for checking one's own shot form before taking a tee shot at a golf course. That is, when a shot is made with the correct form, an exhilarating sound is emitted and a straight trajectory is obtained. When the shot is not correct, the golf practice tool 1 is sliced or hooked to rotate clockwise or counterclockwise when viewed from the plane, and does not even have a hitting sound. In addition, tee shots can be practiced in a garden or the like, and tee shots can be practiced indoors by using a golf practice mat according to the present invention described later.

The golf practice tool 1 is made of at least one selected from the group consisting of flexible paper, resin, alastomer and rubber. The term “flexibility” refers to the property of being able to bend by external stress and restoring the original state when this external stress is eliminated. Any one of paper, resin, elastomer, and rubber may be used or two or more of them may be used in combination as long as they have flexibility.

The paper used in the present invention is not particularly limited as long as it has flexibility. Japanese paper can be used, and Western paper can also be used. Of these papers, western paper, and coated paper is preferably used. Of the coated papers, coated art paper is particularly preferred. This is because it is highly flexible, emits a refreshing sound when shot, and has the same feel as when a real golf ball is shot.

The resin used in the present invention is not particularly limited as long as it has flexibility. For example, polyolefin resin such as polyethylene, polypropylene, polybutene, polyethylene terephthalate, ethylene vinyl acetate copolymer, hydrogenated block copolymer (SEBS) of styrene-butadiene-styrene copolymer, polyvinyl chloride, polyvinyl acetate , Vinyl resins such as polyvinylidene chloride, fluorine resins and rubbers such as polyvinylidene fluoride, acrylic resins and rubbers such as polymethyl methacrylate, polystyrene, acrylic-styrene copolymers, nylon-6, nylon-66, Polyamide resins such as nylon-12, polyester resins, and thermoplastic resins such as urethane resins, urethane resins, epoxy resins, acrylic resins, and unsaturated polyester resins that are cured by applying external energy such as catalyst or heat or light. , Vinyl ester Fat, acrylonitrile - styrene - butadiene copolymer (ABS resin), a styrene - butadiene - styrene copolymer, and the like. Of these, polyolefin resins such as polyethylene terephthalate and ethylene vinyl acetate copolymer, and polyamide resins such as nylon-6, nylon-66, and nylon-12 are preferably used. This is because moldability is good and inexpensive.

The elastomer used in the present invention is not particularly limited as long as it has flexibility. Examples of the elastomer having flexibility include polyolefin-based, polyurethane-based, polystyrene-based, polyester-based, polyamide-based, and polyvinyl chloride-based thermoplastic elastomers. Of these, polyolefin and polyurethane are preferably used. This is because the moldability is excellent.

Furthermore, the rubber used in the present invention is not particularly limited as long as it has flexibility.
Examples of flexible rubbers include diene polymers such as butadiene rubber, 1,2-polybutadiene, polyisoprene, acrylonitrile-butadiene rubber, and styrene-butadiene rubber, acrylic rubber, ethylene-propylene copolymer, and ethylene-propylene. -Non-conjugated diene copolymer, silicone rubber, fluorine rubber, styrene-isoprene rubber and the like.

Of the above-described types of materials, paper and paper coated with resin are preferably used. Paper is inexpensive and easy to manufacture, and is flexible as described above. It produces a refreshing sound when shot and provides the same feel as when a real golf ball is shot. Further, the above-mentioned paper coated with a resin can increase the strength of the paper and increase the water resistance. Resin can be coated on the raw paper before the golf practice tool 1 is produced, or the resin can be coated after the golf practice tool 1 is produced. As the resin used for coating, any one of the above-described thermoplastic resins and curable resins or a combination thereof can be used.

The outer diameter W1 of the hitting portion 10 is 15 mm to 40 mm, preferably 15 mm to 30 mm, more preferably 15 mm to 25 mm in view of the actual golf ball being 42.67 mm. The height H1 is 40 mm to 100 mm, preferably 50 mm to 80 mm, and more preferably 60 mm to 70 mm in consideration of the size of the driver head and the like. The thickness (difference between the outer diameter W1 and the inner diameter W2) is 0.05 mm to 0.5 mm, preferably 0.07 mm to 0.4 mm, and more preferably 0.8 mm in consideration of obtaining a refreshing impact sound and a flight distance. 1 mm to 0.25 mm.

Among these, those having an outer diameter of 15 mm to 25 mm, a height of 60 mm to 70 mm, and a wall thickness of 0.1 mm to 0.25 mm are particularly preferable. This is because within this range, the flight distance is small, it is difficult to break, the feeling when shot is excellent, and a refreshing hitting sound is produced.

Although the outer peripheral surface 11 of this golf practice tool 1 (circular cylinder) may be smooth, it is preferable to provide dimples 14 as shown in FIG. FIG. 2A is a front view when dimples are provided on the outer circumferential surface. The dimple may be concave or convex. 2 (2) is a cross-sectional view taken along the line BB of FIG. 2 (1) when the dimple has a concave shape, and FIG. 2 (3) shows the case where the dimple has a concave shape. It is BB sectional drawing concerning. The size and number of the dimples are not particularly limited, but can be equivalent to a normal commercially available golf ball. When this dimple is provided, the trajectory of the slice or hook is clearly seen.

FIG. 3 shows an example of a golf practice mat that uses the present golf practice tool 1 of the present invention. The golf practice mat 2 includes an artificial turf layer 23 and a shock absorbing layer 24, and the artificial turf layer and the shock absorbing layer have through holes 21 having a regular polygon in plan view. The regular polygon may be, for example, a triangle, a quadrangular system, a pentagon, or a hexagon, but the distance between the facing pieces is the outer diameter W1 of the golf practice tool 1. The golf practice tool 1 is inserted and installed in the through hole 21, and then shot with a golf club driver or the like. When the through hole 21 is a regular polygon in plan view, the golf practice tool 1 can be easily inserted, and the golf practice tool 1 is in contact with the golf practice tool 1 at three or more points. I'm not happy. Of the regular polygons, a regular square is particularly preferable. This is because it is easy to manufacture and can be securely fixed. The through hole 21 may be a circle having the same diameter as the outer diameter W1 of the golf practice tool 1, but lacks the ease of producing the through hole 21.

FIG. 4 is another specific example of the golf practice mat used in the golf practice tool 1. The golf practice mat 2 includes an artificial turf layer 23, a shock absorbing layer 24, and a flexible tee 30 protruding from the shock absorbing layer 24. FIG. 4A is a schematic sectional view of the golf practice mat 2. FIG. 4B shows a state where the golf practice tool 1 is installed on the golf practice mat 2.

The material of the shock absorbing layer 24 is elastic rubber, resin or the like, and the material of the tee 30 is flexible rubber, resin or the like. The method of projecting the tee 30 on the shock absorbing layer 24 can be performed by integral molding or insert molding. Preferably, an impact absorbing layer 24 provided with a fitting hole having a ring-shaped groove and a flexible tee 30 having a ring-shaped protrusion at the bottom are separately formed, and then the fitting hole is formed in the fitting hole. The tee 30 is fitted. This is because when the tee 30 is broken, it can be easily replaced and used.

FIG. 5 shows another example of use of the golf practice tool 1. FIG. 5 (1) is a view in which a currently marketed golf tee 30 is inserted and installed in the ground 40. In the golf tee 30, the upper portion of the golf ball placement portion is formed of a flexible support piece. FIG. 5 (2) shows the golf practice tool 1 installed on the golf tee 30. The flexible support piece of the golf tee is brought into close contact with the inner peripheral surface of the golf practice tool 1 (circular cylinder) to tee up the golf practice tool 1. FIG. 5 (3) is a view in which a golf tee 30 used conventionally is inserted and installed in the ground. FIG. 5 (4) is a view in which the golf practice tool 1 is placed on the golf practice tool 1.

As shown in FIGS. 6 and 7, the golf practice tool 1 for tee shot according to another invention of the present application includes a tee clamping portion 15 inside a circular cylindrical body, and the tee clamping portion 15 has a truncated cone shape with an internal cavity. The frustoconical bottom portion 16 is inscribed in the inner peripheral surface 12 of the bottom of the circular cylindrical body, and the material is at least one selected from the group of flexible paper, resin and elastomer, A plurality of radial slits 18 are provided in plan view from the top 17 to the bottom 16 of the tee sandwiching portion 15.

FIG. 8 is a schematic cross-sectional view when the head of the tee 30 is held by the tee holding portion 15. As shown in FIGS. 8 (1) and 8 (2), the tee pinching portion 15 bends outward to securely pinch the tee head at the inner peripheral surface of the truncated cone constituting the tee pinching portion 15. it can. The material of this tee clamping part 15 will not be specifically limited if it is flexible. Those listed above can be applied.

The material of the tee sandwiching portion 15 may be the same as or different from that of the circular cylinder. In addition, the tee holding portion 15 and the circular cylinder can be integrally formed, or can be formed separately and then bonded together with an adhesive or the like to be integrated. For example, it is also possible to use a foamed resin having a circular cylindrical body made of ethylene-vinyl acetate copolymer resin and the tee holding portion 15 being flexible and having a large elastic deformation.

As the diameter W4 of the bottom portion 16 of the tee holding portion 15, the inner diameter W2 of the circular cylinder described above can be applied. FIG. 8 (1) shows a state where a conventional golf tee that has been commercially available is teeed up. The diameter of the head of this general tee is about 10 mm, and the tee of FIG. In this state, the tee is put up on a commercially available tee, and the diameter of the head of this tee is about 15 mm. Moreover, the head diameter of other commercially available tees is approximately this level. Therefore, in order to tee up the golf practice tool 1 to these tees, the diameter W4 of the bottom portion 16 of the tee holding portion 15 is preferably 20 mm or more.

The diameter W3 of the upper portion 17 of the truncated cone-shaped tee holding portion 15 needs to be smaller than the head diameter of the golf tee 30 shown in FIG. Preferably it is 6 mm-8 mm. The height of the truncated cone is not particularly limited, but it is preferably H1 × 1/3 or less in consideration of teeing up a real golf ball. Further, as shown in FIG. 7, the attachment position of the tee holding portion 15 can be attached so that the bottom portion of the tee holding portion 15 and the bottom portion 13 of the circular cylindrical body coincide with each other. It can also be installed at some distance without matching.

As shown in FIGS. 6 and 7, the tee holding portion 15 includes a radial slit 18 in plan view. 8 is a cross-sectional view taken along the line BB in FIG. Even if the tee holding part 15 provided with the slit 18 is formed of a material having small flexibility, the head of the tee 30 can be securely and stably held. For example, the head of the tee 30 can be securely and stably clamped even if the material is a material such as paper that has low flexibility.

8 (1) and 8 (2) are schematic cross-sectional views when the golf practice tool 1 having a tee holding portion with a slit is teeed up, and when the tee is held as shown in FIG. Since the tee pinching portion 18 opened and bent by the slit bends outward, the head portion of the tee can be pinched securely and stably. FIG. 9 is a schematic perspective view when the golf practice tool 1 having the tee holding portion with the slit is teeed up.
