Even if the club is hit strongly by the club when hitting the ball, the soft protrusion 13 is deformed to flutter in the moving direction F of the club head, and the plate-like base 11 is displaced in the club head moving direction F together with the club. .

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat used for golf practice in which a golf ball (hereinafter abbreviated as "ball") is placed and hit with a golf club (hereinafter abbreviated as "club"). The present invention relates to a golf practice mat.

[0002]

2. Description of the Related Art When a ball is put on a golf practice mat and hit with a club (mainly an iron),
To absorb the impact of hitting the ball or hitting the club too deeply, it is possible to attach a shock absorber to the back of the mat to protect the player's wrists, elbows, etc., or the club or the mat itself. (For example, Japanese Utility Model Application Laid-open No. Sho 60-149669, Japanese Patent Application Laid-Open No. 61-249486).
No., JP-A-63-275357, JP-A-6-3904.
No. 5, etc.).

FIG. 3 is a plan view and a sectional view showing a golf practice mat disclosed in Japanese Utility Model Laid-Open No. 6-39045. This golf practice mat 1 has an artificial turf 2 planted on an upper surface of a plate-like rubber material 3. A concave notch 4 is provided on a lower surface of the rubber material 3, and a polyurethane elastomer 5 is provided on the concave notch 4. Is detachably mounted.

[0004] The mat 1 is provided with a hole 6 for passing a ball from an automatic ball supply device. Rubber material 3
Is provided on the lower surface of the golf club, which is fitted to a recess provided on the floor of a golf driving range or the like to prevent the mat 1 from moving even if the mat 1 is hit. .

[0005]

As described above, even when a shock absorbing material such as a polyurethane elastomer is provided, the shock absorption is insufficient when the mat is hit hard.

[0006] It is an object of the present invention to provide a golf practice mat having extremely excellent shock absorbing properties.

[0007]

A golf practice mat according to the present invention is a golf practice mat having an artificial turf provided on an upper surface of a plate-like base, wherein a number of soft projections are provided on a lower surface of the plate-like base. The soft projection is characterized by being soft enough to be deformed by the force received from the club at the time of hitting the ball and displacing the plate-shaped base.

In the golf practice mat of the present invention, even when the golf club hits a ball with a club, even if the golf club is hit strongly by the club, the soft projection is deformed and the plate-like base is displaced in the club head moving direction together with the club. I do.
Thereby, the impact applied to the player, the club or the mat itself is remarkably reduced.

By making the soft projections tapered, the soft projections can be easily deformed.

[0010] The soft projection is preferably provided on the entire lower surface of the plate-like base. In this way, no matter where the ball is placed on the mat, the impact can be sufficiently absorbed when the mat is hit with a club. Also, by providing the soft protrusions on the entire lower surface of the plate-like base, the plate-like base 11 is displaced as a whole in the club head moving direction, and local distortion is less likely to occur in the plate-like base. .

By forming the soft protrusions integrally with the plate-like base, a mat with soft protrusions can be manufactured efficiently and at low cost.

[0012]

FIG. 1 shows a mat 1 according to an embodiment.
0 (a) is a perspective view from below,
(B) is an enlarged view of a main part of (a), and (c) is a mat 1
0 is a partial cross-sectional view, and FIG. 4D is an explanatory view of a deformed shape when the mat 10 is hit.

The mat 10 comprises a plate-like base 11, an artificial turf 12 planted on the upper surface of the plate-like base 11, and a soft projection 13 projecting from the lower surface of the plate-like base 11.

The material of the plate-like base 11 has a rubber hardness of 40 to 80 of JIS K6301 A type, especially 50 to 80.
70 are preferred.

In this embodiment, the plate-like base 11
And the soft projection 13 are integrally formed.

The soft projection 13 has a pointed conical shape. The soft protrusion 13 is provided over the entire lower surface of the plate-like base 11. In this embodiment, the soft projections 13 are arranged in a staggered arrangement, but may be arranged in a lattice arrangement or the like.

In the golf practice mat 10 configured as described above, even if the golf club hits a ball with a club, even if the golf club is hit strongly by the club, as shown in FIG. The plate-like base 11 is deformed to flutter in the movement direction F, and is displaced in the club head movement direction F together with the club. Thereby, the impact applied to the player, the club or the mat itself is remarkably reduced.

When the club head is driven at a nearly vertical angle, the soft projections 13 are deformed so as to be crushed, and the impact is absorbed.

Since the soft projection 13 has a tapered shape, the soft projection 13 is easily deformed when hit with a club head, and the impact is absorbed sufficiently.

Since the soft projections 13 are provided on the entire lower surface of the plate-like base 11, the impact can be sufficiently absorbed no matter where the ball is placed on the mat. further,
When the mat is hit with a club, the entire plate-like base is displaced in the club head moving direction, so that local distortion is less likely to occur in the plate-like base, and the durability of the mat is improved.

In the golf practice mat 10, since the soft projections 13 have a function of preventing slippage on the floor surface 14 of the golf practice area, the mat 10 is less likely to be displaced.

Since the soft projections 13 are formed integrally with the plate-like base 11, a projection attaching step such as bonding is not required, and the production cost of the mat is low.

In this embodiment, a conical soft projection 1 is used.
Although 3 is used, even if soft projections such as prismatic, truncated pyramidal, cylindrical, pyramidal, and cylindrical shapes are provided as in the case of the soft projections 13a to 13g shown in FIGS. good. Although not shown, FIGS. 2 (a) to 2 (c), (e),
The projection in (f) may be hollow (for example, a rectangular tube).

In the present invention, the height of the soft projection is 2 to
It is preferably 15 mm, especially 3 to 10 mm, particularly preferably 5 to 8 mm. When the soft projections are provided on the entire lower surface of the plate-like base as illustrated, the number (density) of the soft projections is
70-400, especially 30 per 10cm ^{2 of} mat bottom surface
The number is preferably from 200 to 200, particularly preferably from 50 to 100.

In the present invention, when a force of 20 kgf is applied in the horizontal direction by the club, the mat becomes 1 to 5
It is preferable to provide the soft protrusion so that the soft protrusion is displaced by 1 mm to 2 mm, especially by 2 to 3 mm, and is displaced by 1 to 5 mm, particularly 2 to 3 mm when a force of 100 kgf is applied in the vertical direction.

[0026]

As described above, the golf practice mat of the present invention has a very good impact absorption when hit with a club head. This mat can be easily and inexpensively manufactured by integrally molding the soft projection with the plate-like base.
