Abstract

PURPOSE:To stably provide a complex slope by connecting a movable base to a base using more than three bellows type lifting mechanisms which uses fluids as pressure media. CONSTITUTION:A golf training stand 1 comprises a base 2, a movable base 3 and bellows type lifting mechanisms 4a, 4b, 4c connecting the base 2 to the movable base 3. A support ring 5 having an almost circular cross section and an almost circular contour is secured to the lower surface of the movable base 3 and a receiving member 7 having a peripheral groove 6 corresponding to the support ring 5 is provided in the base 2. When a fluid is discharged from a fluid supply source such as a pump and is fed to the exhaust port of the bottom plate 42 of hollow cylindrical bellows via a line, the fluid is either supplied from the port to the bellows or is discharged from the bellows and then a top plate 43 is lifted or lowered and the movable base 3 is lifted or lowered accordingly. In that case the top plate 43 is tilted in accordance with inclination of the movable base 3, so the top plate 43 can be made to follow inclination of the movable base 3 without requiring any special connection means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice table, and more particularly to a golf practice table that can be tilted in all directions.

[0002]

2. Description of the Related Art In a so-called open-air practice field, a ball is practiced on a practice table.

[0003] This type of practice table is usually a horizontal plane, but in an actual golf course, there are inclinations in various directions, and practice with only a horizontal plane cannot handle it.

[0004] Therefore, there have been proposed many things in which a practice table is provided with an inclination so that a ball can be practiced.

In all of these, an elevating mechanism such as a cylinder is provided on the lower surface of the practice table so that, for example, the end edge portion or the side edge portion of the square practice table is raised to form an inclined surface. , The height of the lifting mechanism was large, and the ground had to be dug and installed.

Further, the movable table forming the inclined surface and the elevating mechanism must be connected by a universal joint such as a ball socket, which causes a problem of complicated structure.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a golf practice table provided with a lifting mechanism capable of stably obtaining a complicated inclined surface.

[0008]

In order to solve the above problems, in the present invention, a movable base and a base are connected by a bellows type lifting mechanism using a fluid as three or more pressure media.

[0009]

When the movable table is lifted and lowered by the operation of the bellows type lifting mechanism, each lifting mechanism tilts following the tilt of the movable table, so that no special connecting mechanism is required.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the golf practice table 1 of the present invention comprises a base 2, a movable base 3, and bellows type lifting mechanisms 4a, 4b, 4c for connecting the base 2 and the movable base 3. Become.

A support ring 5 having a substantially circular cross section and a substantially circular contour is fixed to the lower surface of the movable table 3. A receiving member 7 having a circumferential groove 6 corresponding to the support ring 5 is provided on the base 2. It is preferable that the circumferential groove 6 has a semicircular bottom surface as shown in FIG. 2, but the cross sectional shape is not limited thereto. Further, the cross-sectional shape of the support ring 5 may be such that the portion fitted into the circumferential groove 6 is circular.

As shown in FIG. 3, the bellows type elevating mechanism 4a comprises a hollow cylindrical bellows 41 made of a flexible material such as rubber and the upper and lower openings of which are sealed by a bottom plate 42 and a top plate 43. The bottom plate 42 is provided with a pressure medium supply / discharge port 44 formed of a fluid such as air, water, or oil.

When a fluid is supplied to or discharged from the fluid supply source such as a pump via the pipe line 9 at the port 44, the fluid F becomes the port 4.
4 is supplied to the bellows 41 or discharged from the bellows 41, and the top plate 43 moves up and down.

Therefore, when the bottom plate 42 and the top plate 43 are attached to the base 2 and the movable base 3, respectively, as shown in FIG. 2, the movable base 3 moves up and down. At this time, since the top plate 43 is inclined according to the inclination of the movable table 3, it is possible to follow the inclination of the movable table 3 without requiring any special connecting means such as a ball socket. Moreover, since the bellows type lifting mechanism has a low height, the height of the practice table 1 can be made low and compact as a whole.

Now, as shown in FIG. 2, when the elevating mechanism 4a is actuated and raised, the movable table 3 becomes an inclined surface to the upper right. At this time, when the lifting mechanism 4b is raised to a level higher than 4a, the toe goes up, and when it is raised to a lower level, the toe goes down.

In the former case, the support ring 5 and the circumferential groove 6 are in contact with each other in the range of ∠A in FIG. 1, and in the latter case, they are in the range of ∠B.

The number of elevating mechanisms is not limited to that shown in the figure. It may be three or more.

Further, the shapes of the movable base 3 and the base 2 may be round, hexagonal, etc. other than square.

Besides, an artificial turf, a rubber mat or the like can be laid on the upper surface of the movable table 3.

[0021]

As described above, according to the present invention, since the movable base and the base are connected by the bellows type lifting mechanism using the fluid as the pressure medium, the inclination of the movable base can be followed without using any special connecting means. As a result, the top plate of the elevating mechanism tilts, and the movable table can be stably and reliably supported.

Further, since the bellows type lifting mechanism has a low height, the practice table can be made compact, and the labor for digging the ground and installing it is not required.
