Description

[Detailed description of the invention] The present invention relates to an improvement of a golf slope practice table related to golf practice equipment. The objective is to provide a golf slope practice table that has a low angle of inclination and provides a sufficient angle of inclination.

Traditionally, inclined golf practice tables tend to have a high platform height, so it is necessary to dig into the ground to install the base.
There are disadvantages such as the durability of the brake device that fixes the slope plate is low, or the direction that must be constant to obtain the slope angle changes, and it is difficult to adjust the slope angle of various scaffolds while practicing shots. It was extremely difficult to adjust.

The sloped golf practice table of this invention allows you to easily adjust the slope of the foothold while practicing shots, has a constant direction, has a low platform height, and has a sturdy structure. The tilted plate and the rocking frame are pivotally connected by meshing the fan-shaped gear with the worm gear provided on the rocking frame, and then the rocking frame, which is integrated with the tilting board, is rotated orthogonally to the pivoting direction. It is pivoted to the base, and the fan-shaped gear provided at the lower end of the swing frame is meshed with another worm gear that is pivoted on the base.Two pairs of gears and a worm gear The space between the base and the ramp is narrowed by intersecting each other three-dimensionally.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a practice table, and FIG. 2 is a partially cutaway right side view.

Reference numeral 1 denotes a base on which the main body is installed, and it can be expanded in almost the same way as a tilting board 2, which will be described later, or it can be fixed at a facility location.

Reference numeral 3 denotes a support leg erected facing the center of the base 1, and bearings 4, 4 provided at the top of each support leg extend upward from both sides of the swing frame 5 in an inverted V shape. Projection wheels 7, 7 protruding from the sides of the respective tops of the support frames 6, 6 are rotatably supported, and protrusion wheels 7, 7 are provided upright on the opposite sides orthogonal to the protrusion shafts 7, 7 on the swing frame 5. Bearings 9, 9 are provided at the top of the supporting frames 8, 8.

These bearings 9, 9 are provided with brackets erected facing the center of the flat inclined plate 2 having an appropriate width.} 10.10
A pivot shaft 11 horizontally fixed therebetween is rotatably pivoted, and a lever arm 12 extending perpendicularly to the lower part of the inclined plate 2 is fixed at the center of the pivot shaft 11. A fan-shaped gear 13 having the pivot 11 as its axis is provided at the lower end.

Note that the lever arm 12 may be directly fixed to the lower surface of the inclined plate 2.

The sector gear 13 meshes with a worm gear 16 which has a rotating shaft 15 supported by a bracket 14.14 fixed to the lower end of the swinging frame 5, and the rotating shaft 15 extends toward one end of the inclined plate 2. A first rotating handle 17 is provided at the tip.

Further, a fan-shaped gear 18 having the protruding shafts 7, 7 as its axes is fixedly disposed below one side of the swing frame 5 so as to be perpendicular to the fan-shaped gear 13, and the swing frame 5 and the fan-shaped gear 18 are connected to each other. A through hole 19 is defined by the concave portion, and is prevented from colliding with the fan-shaped gear 13 that swings orthogonally.

This fan-shaped gear 18 is a bearing bracket erected on the base 1.
20. It meshes with a worm gear 22 provided on a rotating shaft 21 supported by
The rotating shaft 25 meshes orthogonally with a bevel gear 26 provided at one end of the rotating shaft 25, which is supported by bearing brackets 24, 24 erected on the base 1 so as to be parallel to the rotating shaft 15. axis 25
A second rotary handle 27 is attached to the outer end of the rotary handle 27 in the vicinity of the first rotary handle 17 .

The biggest point of the above structure is that the radius of the two orthogonal sector gears 13 and 18 and the height of the support frames 6 and 8 are adjusted within the range of the distance between the inclined plate 2 and the base 1. to the maximum,
It is to take.

This reduces the unit load applied to the worm gear with which the sector gear meshes, thereby increasing stability in use.

Therefore, the features of the present invention are concentrated in the swing frame 5 and the two pairs of support frames 6 and 8.

That is, the swing frame 5 is fixed to the tilting plate 2, and it is necessary to maximize the radius and install the worm gear 16 that receives the fan-shaped gear 13 and the fan-shaped gear 18 that tilts itself, so that the swing frame 5 is moved as far downward as possible from the tilting plate 2. Must be located remotely.

Therefore, of the two pairs of support frames 6 and 8, support frame 8 extends upward,
It has a protruding shaft 11 at its tip having the center of the sector gear 13 as its axis, and is pivotally connected to the inclined plate 2 via a bracket 10.

On the other hand, the support frame 6 also extends upward and has its own sector gear 18.
It has a protruding shaft 7 having its axis centered at the center of the support leg 3 at its tip, and is pivotally attached via a bracket 4 at the tip of a support leg 3 extending upward from the base.

Here, the above-mentioned abstract expression of maximizing the radius of the sector gears 13 and 18 and the height of the support frames 6 and 8 will be specifically explained.

In other words, the radius of the sector gear, that is, the maximum possible limit with respect to the lever arm 12 and the support frame 8, means that the height of the bracket 10 fixed to the inclined plate 2 is lowered, the center of the bearing portion is brought as close to the inclined plate 2 as possible, and the worm gear is 16 is mounted close to the lower end of the base 1, and the upper end of the worm gear shown in FIG. 1 is lowered as much as possible.

Regarding the fan-shaped gear 18 and the support frame 6, the position of the bracket 4 which is pivotally connected to the support frame 6 should be adjusted so that it does not collide with the bracket 4 when the tilting plate 2 is tilted, as shown by the two-dot chain line in FIG. The height of the support leg 3 is determined by locating it as high as possible, and the worm gear 22 is mounted as low as possible.

By the way, the distance between the upper end of the inclined plate 2 and the lower end of the base 1 is 30 mm.
cm, the radius of the fan-shaped gear should be 23 cm or more, each side of the inclined plate should be 150 cm, and the maximum angle that can be obtained should be around 15 degrees.

Next, a second embodiment will be described.

In this case, the supporting leg 3 is omitted so that the inclined plate 2 does not come into contact with the supporting leg 3 when the inclined plate 2 is tilted about the pivot shaft 11.

That is, in this embodiment, the bracket 4 formed on the top of the support leg 3 in the first embodiment is fixed directly close to the surface of the base 1, and the support frame 6 is extended downward from the swing frame 5 to secure the bracket. 4 via a protruding shaft 7.

Therefore, since the sector gear 18 has the protruding shaft 7 at its center, it is fixedly installed as far upward as possible from the swing frame 5, contrary to the first embodiment, and accordingly, the worm gear 22 and the circuit supporting it are fixedly installed. The driving wheel support bracket 20 is also placed in the upper position of the fan-shaped gear 1.
Merge with 8.

Note that the rotation shaft 21 of the worm gear 22 and the bevel gear 23 are connected by a chain.

As described above, in the second embodiment, the positions of the sector gear 18 and the pivot (protruding shaft) 7 are reversed.

Incidentally, the inclined board 2 has sufficient width and strength for the user to ride on and play shots, and the upper surface of the inclined board 2 is provided with a surface material 28 such as a rubber sheet. 28 can be made of artificial grass or sand if necessary.

The golf slope practice table with the above structure has a first rotating handle 1
7 and the second rotation handle 21, respectively, to the left and right,
The tilting table 2 is used by adjusting it to a desired angle in the front, rear, left, and right directions, and various tilt angles of the shot position in golf can be created.

That is, first, when the first rotation handle 17 is rotated, the worm gear 16 rotates via the rotation shaft 15, so that the sector gear 13 meshed with the worm gear 16 is angularly displaced about the pivot shaft 11.

Therefore, the pivot 11 rotates via the lever arm 12, and the tilting plate 2, which is pivoted to the pivot 11 via the brackets 10, 10, is adjusted in tilt in the angular direction shown by the two-dot chain line in FIG. .

In the second embodiment, when the rotational moment applied in the axial direction of the worm gear 22 is applied to the inclined plate 2 via the sector gear 18, the inclined plate 2 tilts while sliding somewhat.

Next, when the second rotation handle 27 is rotated, the bevel gear 26 is rotated via the rotation shaft 25, and the bevel gear 23 meshed orthogonally with this bevel gear 26 is rotated. As a result, the worm gear 22 begins to rotate.

Therefore, in FIG. 2, the fan gear 18 meshed with the worm gear 22 is angularly displaced about the protruding shafts 7, 7, and the swing frame 5, hereinafter referred to as the support frame 6, becomes integral with the fan gear 18. , 8, bracket 10, other sector gear 12, worm gear 16, rotation shaft 15, handle 17, and inclined plate 2
, is now adjusted in inclination in the angular direction indicated by the two-dot chain line.

The tilt plate 2 can be set at a desired angle by adjusting the tilt angle in the above two directions, and the tilt plate 2 can be set at a desired angle by adjusting the tilt angle in the two directions.
, 7 or the pivot shaft 11 is applied in either direction to the axial direction of the worm gear 16.22, so it is supported by the mesh with the fan gear 13.18, forming a brake structure and rotating on the inclined plate 2. It will not be displaced during play.

As explained above, the tilted golf practice table of the present invention allows the angle of the table surface to be easily changed by simply operating the two rotating handles, and since the two handles are located at almost the same position, Adjustment is easy and the height of the angle adjustment mechanism can be lowered, making it possible to lower the height from the base to the inclined plate, eliminating the need for digging during installation, and eliminating the need for a manual mechanism. Therefore, it is not only simple and requires no construction costs such as power distribution, but also has features such as being extremely easy to get on and off when playing.
