Abstract

PROBLEM TO BE SOLVED: To enable a user to train putt in the nearly same condition as that on actual highly undulating greens by setting slopes which are left-to-right breaking putts and slopes which are right-to-left breaking putts when viewed from a flat part side in the sloping parts of a putt-training mat consisting of an artificial grass mat. SOLUTION: This putt-training mat is constituted by affixing sloping bodies 3 consisting of elastic bodies to the rear surface side of both ends of the artificial grass mat 2 and forming the respective sloping parts BL, BR at both ends of the central flat part A. In the meantime, both angle parts 302, 303 on the boundary line B side dividing the flat part A of the sloping bodies 3 and the respective sloping parts BL, BR are defined as 302, 303 and both corner parts on the end edge line of the artificial grass mat 2 are defined as 301, 304. The front surfaces of the sloping bodies 3 are then divided to two pieces of sloping triangular surfaces varying in the direction of inclination from each other with either one of the diagonal line as a ridgeline 31. The respective front surfaces of the respective sloping parts BL, BR are divided to two pieces of sloping green surfaces 32a, 33a formed with the sloping triangular surfaces along the respective sloping triangular surfaces and cups 41, 42 are respectively disposed at these surfaces.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter practice mat made of an artificial turf mat.
The present invention relates to a putter practice mat provided with various undulations at arbitrary positions.

[0002]

2. Description of the Related Art In a golf shop or the like, when you stop by a putter sales corner, you often see a putter practice mat made of an artificial grass band that resembles a green. FIG. 6 shows a general putter practice mat as an example.

The putter practice mat 1a is composed of an artificial turf-like mat 2 made of a single band-like body, and a slope 3a having a triangular cross section is provided on the back surface at one end side so that a predetermined climbing gradient from the flat portion A is obtained. Is formed. The inclined portion B is provided with a cup 4 into which a golf ball 5 enters.

[0004]

However, since the putter practice mat 1a of this type has a simple inclined surface even if there is an inclined portion B, the putter practice mat 1a is used to hit the ball straight or to adjust the distance. I can only practice. Therefore, even if you buy it, you get tired immediately,
It is often seen as so-called dead goods.

[0005] Therefore, there has been known a golf club in which the inclination angle can be variously changed so as to resemble an actual golf course green. For example, in Japanese Utility Model Laid-Open Publication No. 2-39777, a hook line or a slice line is obtained for a cup by arranging an inclined plate having a triangular cross section on the back surface along one side of the length of the band-shaped mat. In order to change the line, however, it is troublesome to change the inclined plate one by one, and the hook or slice line has few variations.

[0006] In addition, there is a type in which the inclination angle of the inclined plate having a cup can be changed manually or by an automatic mechanism such as a motor, but in any case, the structure is complicated and expensive. In addition, since this type cannot be easily folded, it is difficult to find a storage place when not in use.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has an object of practicing a putter in almost the same situation as on an actual undulated green with a simple structure. It is an object of the present invention to provide a putter practice mat that can be used.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an artificial turf-like mat having a flat portion and an inclined portion connected to at least one end of the flat portion. An inclined body provided on the back surface of the artificial turf-like mat to form, in a putter practice mat in which a cup is formed in the inclined portion, the inclined body is
The upper surface of the rectangular parallelepiped including the boundary between the flat portion and the inclined portion on one side thereof is divided into first and second inclined triangular surfaces having different inclination directions with one of the diagonal lines as a ridge line, A first inclined green surface is formed on the inclined portion at the first inclined triangular surface so as to be ascending from the boundary line portion, and the second inclined triangular surface is descended from the ridge line toward an opposing vertex at the second inclined triangle surface. A second inclined green surface having a gradient is formed, and a cup is provided on each of the inclined green surfaces.

As described above, the inclined portion has a first inclined green surface having an ascending gradient from the boundary between the flat portion and the inclined portion, and a second inclined green surface having a descending gradient from the ridge line to the opposing vertex.
An inclined green surface is formed, and the rolling direction of the ball changes at the ridgeline. Therefore, even if it is a practice mat, it is possible to practice putter in a difficult situation which has never been seen before.

In the present invention, it is preferable that the inclined portions are provided symmetrically at both ends of the flat portion. According to this, it is possible to strike the ball from the flat portion to the left or right. You can practice along the hook line or the slice line.

Further, by using a submat consisting of a substantially three-dimensional trapezoid arranged at an arbitrary position on the back surface of the flat portion, it becomes possible to set a more complicated undulation on the practice mat surface, as in the prior art. Never get bored.

It is preferable that a marker is provided which is detachably attached to an arbitrary position on the flat portion and the inclined portion, so that the marker can easily change a direction in which the ball is launched or a direction in which the ball changes direction. Can be grasped.

Further, it is preferable that the cups are provided on the first and second inclined green surfaces in different sizes. For example, making one cup smaller than that of the general standard can help polish more accurate putting techniques.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to an embodiment shown in the drawings.

FIG. 1 shows a putter practice mat 1 according to this embodiment laid on the floor. The putter practice mat 1 includes an artificial turf-like mat 2 made of a single strip, and inclined bodies 3 and 3 made of an elastic material such as a sponge are attached to the back surfaces of both ends thereof. As a result, the inclined portions B are provided at both ends of the central flat portion A.
L and BR are formed respectively. The putter practice mat 1 can be wound up or folded.

Each of the inclined bodies 3, 3 has the same configuration except that they are arranged symmetrically with respect to the central flat portion A. Therefore, here, the inclined bodies arranged on the back surface of the left inclined section BL in FIG. 3 will be described with reference to the perspective view of FIG.

According to this, the inclined body 3 has a rectangular parallelepiped shape including a virtual boundary line B between the flat portion A and the inclined portion BL on one side thereof. Then, both corners on the boundary line B side are 302,
303, the two corners on the edge side of the artificial turf mat 2
Assuming that 304, the upper surface of the inclined body 3 has a first and second inclined triangular surfaces 32 having different inclination directions from each other with a diagonal line (a diagonal line connecting the corners 301 and 303 in this embodiment) as a ridgeline 31. It is divided into 33.

That is, the first inclined triangular surface 32 is
In this case, the corners 301 are left as the original thickness of the rectangular parallelepiped, while the other two vertices 302 and 303 have the thickness as viewed from the corners 301. The first inclined triangular surface 32 is cut so as to have a thickness of substantially 0, whereby the first inclined triangular surface 32 has a high corner portion 301 and a lower side such that the side of the boundary line B opposed thereto is substantially flush with the flat portion A. It is formed as an inclined triangular surface.

Similarly, the second inclined triangular surface 33 is
A triangle having each vertex at 1,303,304, the corner 301 is high, and the side between the corners 303,304 opposite thereto (a part of the long side of the artificial grass mat 2) is flat. Part A
Is formed as an inclined triangular surface which is lowered so as to be substantially the same as the surface.

The right inclined portion BR is obtained by rotating the inclined body 3 of FIG. 2 by 90 degrees counterclockwise in FIG.
That is, the inclined body 3 is rotated in such a manner that the corner 301 having the highest height comes to the position of the corner 302 in FIG.
Are arranged on the back surface of the right inclined portion BR.

Therefore, the upper surfaces of the inclined portions BL and BR are formed by a first inclined green surface 32a and a second inclined green surface which are formed as an inclined triangular surface along the first inclined triangular surface 32 and the second inclined triangular surface 33. 33a.

That is, when the inclined portion BL is viewed from the flat portion A side, the first inclined green surface 32a is formed as an inclined triangular surface having an ascending slope from the boundary line B, and the second inclined green surface 33a exceeding the ridge line 31 is formed. An inclined triangular surface having a downward slope toward the vertex 304 is formed.

When the inclined portion BR is viewed from the flat portion A side, the first inclined green surface 33a is formed as an inclined triangular surface having an ascending slope from the boundary line B, and the second inclined green surface 32a which exceeds the ridge line 31 is formed. An inclined triangular surface having a downward slope toward the vertex 302 is formed.

Each inclined green surface 32 of the inclined portions BL and BR
a and 33a are provided with cups 41 and 42, respectively. In this embodiment, the first and second cups are closer to the flat portion A.
Sloped green surface (32a on slope BL side, slope BR
On the side, the cup 41 provided in 33a) has a smaller diameter than the general standard, and the second side on the side that has passed over the ridgeline 31
The inclined green surface (33a on the inclined portion BL side, the inclined portion BR
On the side, the cup 42 of 32a) has a standard diameter.

According to the putter practice mat 1, as shown in the schematic diagram of FIG. 3, for example, the first part of the left inclined portion BL is puttered from a substantially central position CR on the right side of the flat portion A.
When the golf ball 5 is launched straight toward the inclined green surface 32a, a hook line as shown by a virtual line CR1 that bends toward the cup 41 along the inclined surface from a point beyond the boundary line B is obtained.

The second inclined green surface 33a extends over the ridgeline 31 of the left inclined portion BL from the same center position CR.
When the player puts strongly on the cup 42 at the point, the ball is sliced as indicated by the virtual line CR2 when the ridgeline 31 is crossed, so that the slicing line can be practiced.

On the contrary, if the golf ball 5 is hit straight from the approximate center position CL2 on the left side of the flat portion A toward the first inclined green surface 33a of the right inclined portion BR with a putter, the boundary From the point beyond the line B, a slice line as shown by a virtual line CL1 that bends toward the cup 41 along the inclined surface is obtained.

The second inclined green surface 32a extends over the ridgeline 31 of the right inclined portion BR from the same center position CL.
When the player puts strongly on the cup 42 at the point, the ball hooks as shown by the virtual line CL2 when the ridgeline 31 is crossed, so that the practice of the hook line can be performed.

That is, even with the same hook line, a relatively easy hook line CR1 can be obtained from the substantially central position CR on the right side of the flat portion A, and from the substantially central position CL2 on the left side of the flat portion A. In this case, a hook line CL2 that is difficult to cross over the ridgeline 31 is obtained.

Similarly, even with the same slice line, a relatively gentle slice line CL1 is obtained from the substantially central position CL on the left side of the flat portion A, and the substantially central position on the right side of the flat portion A is obtained. In the case of CR2, a slice line CR2 that is difficult to cross the ridgeline 31 is obtained.

Further, the first inclined green surfaces 32a, 33a
Since each hem has a gentle slope, a straight line can be obtained by putting on an imaginary line SL connecting the two cups 41 near the boundary line B and aiming at one of the cups 41. Can practice.

The above is an example of a putter practice scene, and it goes without saying that the practice can be performed assuming various situations by aiming at a desired cup from an arbitrary position of the flat portion A. No.

Further, the putter practice mat 1 is provided with a sub-mat 6 as an accessory as shown in FIG. 4 so that the flat portion A has an undulation. In this embodiment, the sub mat 6 is formed of a three-dimensional trapezoidal sponge body.

That is, the sub-mat 6 has a gentle first inclined surface 6a whose thickness is reduced at a predetermined ratio from the top side 60 to one long side 61 in the longitudinal direction.
And a pair of second inclined surfaces 6b, 6 formed in a triangular shape and formed from both ends of the top side 60 to the short sides 62, 62 in the width direction.
b, and a steep third inclined surface 6 c formed from the top side 60 to the other long side 63.

As shown by the broken line in FIG. 3, the sub-mat 6 is detachably installed at an arbitrary position on the back surface of the flat portion A, and forms an appropriate mound at the installation portion. Therefore, by using this sub mat 6, the putter practice mat 1 can be made a more tricky pseudo green.

Also, the putter practice mat 1 is provided with an appropriate number of markers 7 punched out of a sheet with an adhesive material, for example, in a circular shape as an accessory, and examples of its use are shown in FIGS. ).

That is, as shown in FIG.
By sticking the markers 7, 7 at predetermined positions before and after the golf ball 5 to be hit, the method of taking a back swing stroke and the hitting direction can be practiced using the markers 7, 7 as a guide.

FIG. 5B shows an example in which a marker 7 is attached near the cup 4 as a target for reading, for example, a hook line for the cup 4. In this way, by using the marker 7, it is possible to practice putters in a realistic situation with the target set firmly, instead of just practicing loosely.
