The present invention relates to a swinging footboard for golf practice inclination adjustment, more specifically, the piston end of the four hydraulic jacks are respectively fixed to the bottom of the foothold footboard is fixed to each of the four supporters formed with spherical grooves and controlled by the control unit By installing a hemispherical piston head in point contact with the spherical groove of each support to support the turn at tread, the turn tread can be adjusted to various inclination directions and inclination angles, and the structure is simplified to further install and maintain. The present invention relates to a sprinting footboard for golf practice that can be tilted to further improve safety by enabling the stalking footboard to be installed as close to the ground as possible without using additional basic construction.

In general, when playing golf on a real field such as a golf course of a country club, most of the iron shots or approach shots except the tee shot are performed at a predetermined slope, not on a flat surface, and therefore, irons are not normally performed on a golf field. When practicing shots or approach shots, it was necessary to practice where the slope was formed to match the actual field as much as possible in order to improve the adaptability to the actual field. The demand for a golf practice footstool that can be tilted under the same slope conditions as the field has been gradually increasing.

However, in order to cope with the increase in demand for the golf practice turntable footrest that can be tilted as described above, a number of tilting control footsteps for golf practice have been devised and registered or registered, but most of the first application or registration cases are inclined. Too large or complex structure of the device to form a not only difficult installation and maintenance, but also the manufacturing cost is too high, there was a deterioration in profitability.

In addition, the operation method of the device is inconvenient and difficult to use, or the stool footboard to be raised by the golfer is placed too high from the ground, causing anxiety to the golfer when it is used or severe risk of falling of the golfer. It was a situation.

In order to secure such safety, there was a method of digging in the ground so as to lower the ground height of the stool footstep as much as possible, but this is also applicable only to the newly constructed golf practice ground, but it is applicable to the existing golf practice ground. There were various practical problems, such as the need for additional construction of the back.

As described above, the prior practice or registered inclined adjustable slab for golf practice, although a number of devises are known, there are almost no examples that are actually applied to the golf practice site because it contains problems that are extremely unsuitable for the practical use and commercialization of the device. There was no situation.

In order to solve the above problems, the present invention fixedly installs four supporters each having spherical grooves formed on the bottom surface of the turn at step plate, and the piston end portions of the four hydraulic jacks respectively controlled by the control unit are in point contact with the spherical grooves of the respective support units. By fixing the hemispherical piston head to support the turntable footrest, the turnboard footrest can be adjusted to various inclination directions and inclination angles, and the structure is simplified to make installation and maintenance easier and to minimize the installation area. It is a technical task to be able to install the striated footrest as close to the ground as possible without further incidental foundation work to further improve safety.

In order to achieve the above technical problem, the present invention is a flat plate-shaped plate and a hydraulic jack that is installed at the bottom of the plate, and the piston inserted into the housing up and down to adjust the inclination of the plate plate, and In the golf practice swinging foot stool that is inclined adjustable consisting of a control unit that is connected to each of the hydraulic jack and the control wiring to control the hydraulic jack, respectively, the bottom portion of the turn stool is fixed fixed support is provided with a concave groove portion And a hemispherical piston head fixedly attached to each of the spherical grooves of the support to support the turntable footrest at each piston end of the hydraulic jack. The auxiliary support is fixed to the outer periphery of the supporting support It characterized.
