Description

The present invention relates to a device that enables golf shot practice on various slopes in golf.

At the so-called driving range, you practice shots by placing the ball on an artificial turf mat on a flat floor. However, in an actual golf course, it is necessary to deal with various conditions (lie) such as toe up and toe down, left foot up and left foot down.

When the lie has a raised toe, the swing surface formed by the trajectory of the club is closer to the plane by the angle of the raised toe compared to a flat lie, and as a result, the ball flies to the left with respect to the flat case. If the lie has a lower toe, it will fly to the right. Also, when the left foot rises, it acts as if the loft angle of the club has increased, and even if the same swing as when flat is achieved, the ball rises higher and the flight distance becomes shorter. On the contrary, when the right foot rises, the height of the ball is low and the flight distance is extended.

A practice table for practicing shots assuming a lie like an actual course has also been invented, but a relatively large-scale device such as a hydraulic cylinder is assumed for the elevator for inclining the striking table. (For example, patent document, non-patent document 1).

There are also training aircraft that use multiple drive motors, but the control mechanism is relatively complicated, and the batter's boarding support point is limited to a small area in the center (for example, non-patent documents). 2).

The challenge is to inexpensively manufacture a batting table that creates all the slopes experienced in a round shot of golf by a smooth and simple method.

A semi-circular gear that can rotate in the direction perpendicular to each axis in the front-back direction and the left-right direction is attached to the lower part of the striking plate, and by a simple method that utilizes the geometric characteristics of the combination of the two semi-circular gears. ， Consists of these striking plates and a base plate equipped with a support device equipped with a reduction motor that holds the striking person and rotates the semicircular gear.

In order to rotate the two sets of semicircular gears independently, the diameters of both semicircular gears should be different, and the longer diameter semicircular gear should not be hindered by the shorter diameter. In addition, the arc portion in which the shorter semicircular gear rotates is formed in a ring shape, and the diameter of the shorter semicircular gear is set to be less than or equal to the inner diameter of the ring.

The hitter sits above the support of these devices. The control device installed at the right end of the front is set to tilt in any desired direction by the switch of the reduction motor. At the center end of the tip, a ball is placed on a cylindrical rubber tee on a ball installation device that always faces in the vertical direction within an arbitrary solid angle by a weight at the bottom and a spherical bearing for shots.

In the golf practice table of the present invention, the hitter can smoothly set the desired direction and angle of inclination by the switch control placed on the hitting plate.

The ball can always be placed on the rubber tee of the ball installation device, which faces vertically, allowing you to practice the situations you encounter on a real golf course.

This is an example of an embodiment in an initial state in which the front view and the inclination are not provided. This is an example of an embodiment in an initial state in which a side view and an inclination are not provided. This is an example of a side view and an embodiment in which the toes are raised. It is a perspective view of the sliding part. Plan view. The left side is a cross-sectional view taken along the straight line AA'shown in side view 1. Enlarged view of the ball installation device. It is a straight line B-B'line sectional view shown in the plan view 5.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.

FIG. 1 is a front view of the apparatus of the present invention, and FIG. 2 is a side view of the same embodiment, which is an example of an embodiment in an initial state without inclination.

The golf practice table of the present invention is responsible for tilting in the front-rear direction and the left-right direction installed on the lowermost substrate 1 shown in each figure, and supports the striking plate 2 on which the upper artificial turf mat 3 is installed and the hitter. It is composed of two sets of sliding devices 4a to 8a and 4b to 8b, a ball installation device 9, and a control device 10.

FIG. 3 is a side view showing an example of an embodiment in which the toes are raised. The striking person stands on the upper part of the sliding portion of the mat 3 stretched on the striking plate 2 and tilts the striking plate as shown in FIG. 3 of the embodiment by pressing the switch of the control device 10 placed at the right end of the striking plate. Let me.

FIG. 4 shows a perspective external view of the sliding portion from the front right when the striking plate has a composite inclination of the toe rising and the right foot rising.

FIG. 5 is a plan view. The left side is a cross-sectional view taken along the straight line AA'shown in side view 1, showing the structure of the sliding portion. The right side is an upper plan view, in which the ball installation device 9 is placed at the center of the tip and the control device 10 is placed at the right end.

FIG. 6 is an enlarged view of the ball installation device 9. The ball installation device includes a spherical bearing 11, a weight 12, and a rubber tee 13 for ball installation. The free support 11 is attached to a mounting jig 14 and fixed to a striking table 2. The ball 15 and the weight 12 are always oriented in the vertical direction by the spherical bearing 11 regardless of the inclination of the striking table.

As described above, the batter presses the switch of the control device 10 on the mat on the batting plate 2 with his hand or the tip of the club, and raises his toes, raises his right foot and a combination thereof, and further tilts the reverse direction. The slope can be set smoothly and easily. At this time, the rubber tee 13 of the ball installation device 10 always faces the vertical direction, and the ball can be addressed and shot after the ball is installed.
