As shown in FIG. 14, the compression spring 42 is compressed against the compression spring 42 while rotating around the rotation shaft 38 in the counterclockwise direction in FIG. 14, and the block 35 is simultaneously turned to four hydraulic circuit open / close limit switches 14. The hydraulic circuit open / close limit switch 14 is in the “open” state, and as shown in FIG. 8, all the pipes 25, 26, 30, 31 are opened, and the oil 27 is A state of freely flowing in the pipe, that is, a release mode is switched.
As shown in FIG. 14, the lower end 33c of the release operation lever 33 is engaged with the notch groove 49a of the link 49, so that the release operation lever 33 is restrained by the link 49 and is released unless the fixing operation lever 34 is pushed. The mode will be maintained.

Therefore, the person 3 on the practice table 4 can incline the practice table 4 in an arbitrary direction by moving his / her weight. For example, the person 3 shown in FIG. The inclination of the practice base 4 can be changed to the state of.
When the body weight is moved, the tilt angle and the tilt direction of the practice base 4 change. This change is caused by the expansion and contraction of the hydraulic cylinders 9A and 9B (arrows H and I in FIG. 8) and the actions of the universal joints 7A and 7B. And the spherical bearings 23 are absorbed and smoothly allowed, and a pair of orthogonal arc-shaped guide members 10A and 10B are supported by the guide rollers 21 of the pair of guide support members 11A and 11B, respectively. It is extremely smooth and powerful, reliably guided and smooth.

When the desired inclination is obtained, the head 18a of the golf club 18 pushes the concave portion 34d of the fixing operation lever 34, so that the fixing operation lever 34 compresses this against the compression spring 43 while turning in FIG. Since the bracket 45 pulls down the link 49 via the link 44 by rotating clockwise, the lower end 33c of the release operation lever 33 is released from the notch groove 49a, and as a result, the restoring force of the compressed compression spring 42 causes the The release operation lever 33 rotates clockwise in FIG. 14 and returns to the original position.

As a result, the pressing of the actuator 14a of each hydraulic circuit open / close limit switch 14 is released, so that the hydraulic circuit open / close limit switch 14 is in the “closed” state, the hydraulic circuit 13 is in the hydraulic lock state, and the hydraulic cylinder 9A. , 9B cannot move, and the exercise table 4 is fixed at the inclination shown in FIG. 16, and the inclination does not change even if the weight of the person 3 moves thereafter. The person 3 can move forward freely and can practice shots under the same conditions as the horizontal slopes.

Similarly, as shown in FIG. 17, the hydraulic circuit 13 is set to the release mode by pressing the recess 33 d of the release operation lever 33 with the head 18 a of the golf club 18, and is lowered forward by the weight shift, and is inclined horizontally to the desired level When the inclination is obtained, the hydraulic circuit 13 is switched to the fixing mode by pushing the concave portion 34d of the fixing operation lever 34 with the head 18a of the golf club 18, and the practice table 4 no longer moves depending on the weight movement of the person 3. Therefore, the person 3 can move forward and practice the same shot as the left and right sloping ground.

Similarly, as shown in FIG. 18, if the practice base 4 is tilted to the left for the person 3 and tilted horizontally in the front-rear direction, the shot can be practiced under the same conditions as those on such an inclined ground.

As described above, according to the present invention, it is not necessary to control the hydraulic cylinder 9 in a complicated manner, and by simply switching the release mode or the fixed mode of the hydraulic circuit 13, the inclination of the practice table 4 can change the weight movement force of the person 3. Therefore, the golf practice table apparatus 1 can be manufactured and provided at low cost, and the operation of the operation unit 16 by the golf club 18 on the practice table 4 is simple and extremely useful. It is an invention.
