BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf training device which can be tilted in all directions.

[0002]

2. Description of the Related Art Conventionally, as a golf practice table that can be tilted in all azimuth directions, a tilting plate-like portion is freely erected and connected via a joint on a base, and at least two or more tilting members are used. The base ends of the cylinders are pivotally supported on the base so as to be vertically or omnidirectionally rotatable, and the tilting cylinder tip pivotal support is always located on the tilt axis extension of the universal joint. It is known that the golf practice table (No. 1-161771, Kaikaidaira).

[0003]

However, in this apparatus, in addition to the tilting mechanism of the tilting plate-shaped portion, a separate tilting mechanism allows tilting in all directions, which makes the mechanism complicated. There is.

[0004]

[Means for Solving the Problems] In order to solve the above problems, in the present invention, the rear end of the ball stand and the front end of the golf practice table are hinged, and the center of the golf practice table is supported. A pillar is provided in the center of the base, and two screw pillars that support the left and right sides of the rear end of the practice table are provided on the left and right sides of the rear end of the base with respect to the pillar, and the lower surface of the practice table and the pillar The upper end of the screw column is swingably connected by a spherical joint, and further the screw column can be moved up and down by a motor-driven speed reducer, and a shaft box swingably coupled to the screw column by a spherical joint is formed. The present invention proposes a golf practice device in which a brake plate, one piece of which is attached to the axle box, is compressed by a spring member, and one end of the practice table is attached to the brake plate.

[0005]

In other words, according to the present invention, the center of the base and the upper ends of the screw columns provided on the left and right sides of the rear end of the base are connected to the lower surface of the golf practice table through spherical joints. When one of the screw columns provided on the left and right sides is moved up and down by a motor-driven reducer,
With the spherical joint at the upper end of the strut as the fulcrum, the practice table tilts as the screw column moves up and down, and when the other screw column moves up and down, it tilts in the same way. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiments. 1 is a ball stand, 2 is a golf practice table on which a golfer rides, and the rear end of the ball stand 1 and the front end of the golf practice table 2 are shown. The space between and is hinged by talking number 3.

A pillar 5 supporting the central portion of the golf practice table 2 is provided at the center of a base 4 located below the golf practice table 2, and a spherical joint 6 is provided between the lower surface of the practice table 2 and the upper end of the pole 5. It is connected so that it can swing.

On the other hand, two screw columns 7 and 7 are provided on the left and right sides of the rear end of the central portion of the base 4 on which the columns 5 are provided.

In this embodiment, the screw column 7 is composed of an inner cylindrical body 7a having a male screw threaded on its outer circumference and an outer cylindrical body 7b having a female thread screwed on the male thread on its inner circumference. Is rotatably planted on one side of the rear end of the base 4, and is connected to a speed reducer 9 driven by a motor 8 on the upper end thereof, while being planted on the base 4 on the outer cylinder body 7b. The guide piece 11 guided by the guide pillar 10 is fixed.

A shaft box 13 having a spherical joint 12 is provided on the inner circumference of the outer cylindrical body 7b, and brake plates 14 and 15 are fitted on the lower end of the outer circumference of the shaft box 13 to fit the brakes. A spring member 16 is fitted on the plate 15, a nut 17 is screwed on the spring member 16, and a golf practice table 2 is provided between the fixed piece 14 and the movable piece 15.
The mounting plate 18 on one side of the rear end portion is clamped and fixed.

On the other hand, a fairway practice plate 19, a tee shot practice plate 20, a rough practice plate 21 and a ball box 22 are provided on the ball base 1, and a rubber piece 23 for preventing rolling of the ball is further provided on the outer periphery thereof. It is provided.

Further, a gutter 24 for storing a preliminary ball is provided along the front end of the ball base 1, and the storage ball provided in the gutter 24 is moved by the foot lever 25 to the practice plates 19 and 20, respectively.
Supplied to 21.

The ball base 1 can be tilted in the front-rear direction by a handle or a motor drive separately from the golf practice table 2. Therefore, in this embodiment, a handle 26 and a speed reducer 27 are provided.

In this embodiment, the screw columns 7 and 7 are
A foot switch 28 for driving the motor for moving up and down is provided on the practice table 2 in the vicinity of the screw columns 7 and 7, and as the screw columns 7 and 7 are moved up and down, the ball table 1 and the golf practice table 2 are tilted. Limit switches 29 for stopping the motor 8 when the maximum angle is reached are provided on the lower surfaces of the four corners of the ball base 1 and the golf practice table 2.

In the above structure, the golfer rides on the practice table 2, sets the ball on any of the practice plates 19, 20, 21 of the ball table 1, and then inserts the foot switch 28 to screw the pillars 7, 7. Is appropriately elevated to incline the ball stand 1 and the practice stand 2 at a predetermined angle.

In this case, when the foot switch 28 is turned on,
The inner cylinder 7a of the screw column 7 is rotated by the motor 8,
This rotation raises and lowers the outer cylinder body 7b, and along with this, the axle box 13
Moves up and down, but the brake plate 14 provided on the outer circumference of the axle box 13
Between 15 and 15 is a mounting plate 18 on one side of the rear end of the golf practice table 2.
, A spherical joint 6 is provided between the lower surface of the center of the golf practice table 2 and the upper end of the support column 5, and a spherical joint 12 is provided between the axle box 13 and the outer cylinder body 7b. As a result, the golf practice table 2 and the ball base 1 tilt in a circular motion around the support column 5 by the above-mentioned elevation. Therefore, the ball switch 1 and the practice table 2 can be tilted in all directions by 360 degrees by adjusting the elevation of the screw columns 7 and 7 with the foot switch 28.

Since the practice table 2 makes a circular motion around the support column 5 with respect to the linear up-and-down movement of the outer cylindrical body 7b, a hole with a margin is provided in the mounting plate 18 in order to eliminate the gap.
Insert the axle box 13 into this, and further attach the brake plates 14 and 15 to the mounting plate.
I am trying to move the practice table 2 while holding 18 pieces.

The braking force by the brake plates 14 and 15 can be adjusted by adjusting the elasticity of the spring member 16 with the nut 17.

In addition to the practice table 2, the ball table 1 can be tilted forward and backward by the handle 26.

In this embodiment, the practice table 2 moves up and down at a speed.
At 400 mm / min, the tilt angle is in the range of 0 ° to 12 °.

Further, in this embodiment, since the fairway practice plate 19, the tee shot practice plate 20, and the rough practice plate 21 are provided on the ball base 1, the respective exercises can be performed.

Further, in this embodiment, the limit switch 29
Since the screw pillar 7 is automatically stopped at the maximum inclination angle of the practice table 2, the golfer can practice without operating the foot switch 28.

[0023]

In summary, according to the present invention, the practice table can be tilted in all directions with safety and reliability with an extremely simple mechanism.
