CROSS-REFERENCE TO RELATED APPLICATION

This application is a U.S. national stage application of PCT international application PCT/JP2015/056936, filed on Mar. 10, 2015 and claims the priority benefits of Japanese Patent Application No. 2014-047134, filed on Mar. 11, 2014, Japanese Patent Application No. 2014-120213, filed on Jun. 11, 2014, and Japanese Patent Application No. 2014-195961, filed on Sep. 26, 2014, respectively, the contents are incorporated herein by reference.

BACKGROUND

1. Technical Field
The present invention relates to an inclined golf mat and a golf mat assembly suitable for being laid and used in an outdoor or indoor golf practice range, a yard or a parking lot in a home of a golfer (a practicing person), and the like.
2. Background Art
In a golf course, even on a fairway, there are not only flat places but also places undulated in complicated curved surface shapes. On the other hand, in a golf practice range, in most cases, there are only flat places. Therefore, in such a golf practice range, practice of shots and putting corresponding to undulations of an actual golf course cannot be performed.
Therefore, in recent years, it has been attempted to give inclination to a golf mat laid in a golf practice range assuming an actual golf course. As a golf mat of this type, there has been proposed a golf practice platform in which a shot platform is provided on a base frame to be tiltable to the front and the back and the left and the right via a tilt driving section (see, for example, Japanese Patent Laid-Open No. 2011-67303).

SUMMARY

However, in such a golf practice platform, the tilt driving section including guide rails, slide cams, cam subsections, and an inclined supporting section is essential as a mechanism for inclining the shot platform. Therefore, there is a problem in that the structure of the golf practice platform is complicated and, in addition, since metal is used as a material of the golf practice platform, a price necessarily increases and versatility is not so high.
In view of such circumstances, a first object of the present invention is to provide an inclined golf mat with which it is naturally possible to perform practice of shots and putting corresponding to undulations of an actual golf course and that is inexpensive and has high versatility because the inclined golf mat is simple in structure and can be reduced in weight. A second object of the present invention is to provide a golf mat assembly composed of such an inclined golf mat.
In order to achieve such objects, in an inclined golf mat according to the present invention, a surface section including an inclined surface is detachably attached to an upper side of a base, a first fitting section is provided on an upper surface of the base, and a first section to be fit that fits with the first fitting section is provided on a lower surface of the surface section.
In the inclined golf mat of the present invention, one of the first fitting section and the first section to be fit may be projected, and a plurality of the other sections may be recessed at a predetermined pitch.
In the inclined golf mat of the present invention, the surface section may include an outermost layer member including the inclined surface and a wedge-shaped intermediate member located on a lower side of the outermost layer member and including the first section to be fit on a lower surface, and a second fitting section may be provided on an upper surface of the intermediate member, and a second section to be fit that fits with the second fitting section may be provided on a lower surface of the outermost layer member.
In the inclined golf mat of the present invention, one of the second fitting section and the second section to be fit may be projected, and a plurality of the other sections may be recessed at a predetermined pitch.
In the inclined golf mat of the present invention, the second section to be fit may be configured to fit in the first fitting section, and one of the first fitting section and the second section to be fit may be projected in a substantially semispherical shape and the other may be recessed in a substantially semispherical shape.
In the inclined golf mat of the present invention, the base may contain an upper side board and a lower side board, the first fitting section may be provided on an upper surface of the upper side board, a third section to be fit may be provided on a lower section may be provided on an upper surface of the lower side board.
In the inclined golf mat of the present invention, a bottom-up member to adjust height of the surface section with respect to the base may be interposed between the base and the surface section.
In the inclined golf mat of the present invention, the bottom-up member may include a plurality of columns and a plate placed on upper sides of the columns, in each of the columns, a fifth fitting section may be provided on an upper surface and a fifth section to be fit that fits with the first fitting section may be provided on a lower surface, and, in the plate, a fourth fitting section that fits with the first section to be fit may be provided on an upper surface and a fourth section to be fit that fits with the fifth fitting section may be provided on a lower surface.
In the inclined golf mat of the present invention, the bottom-up member may include a framework having a substantially rectangular parallelepiped box shape, and, in the framework, a sixth fitting section that fits with the first section to be fit may be provided on an upper surface and a sixth section to be fit that fits with the first fitting section may be provided on a lower surface.
In the golf mat of the present invention, the surface section may include a natural turf in an outermost layer.
Further, in a golf mat assembly according to the present invention, a plurality of the inclined golf mats are coupled in a horizontal direction.
With the inclined golf mat of the present invention, since the outermost layer member of the inclined golf mat includes the inclined surface, it is naturally possible to perform practice of shots and putting corresponding to undulations of an actual golf course. It is possible to easily assemble the inclined golf mat by fitting the first fitting section of the base and the first section to be fit of the intermediate member. Since synthetic resin or the like can be adopted as the material of the inclined golf mat, the inclined golf mat is simple in structure and can be reduced in weight. Therefore, it is possible to provide the inclined golf mat that is inexpensive and has high versatility.
In the inclined golf mat of the present invention, one of the first fitting section and the first section to be fit is projected and the plurality of the other sections are recessed at the predetermined pitch. Therefore, when the surface section is attached to the upper side of the base, it is possible to optionally adjust an attachment position of the surface section with respect to the base in units of the pitch of the first fitting sections or the first sections to be fit. As a result, when the plurality of inclined golf mats are coupled in the horizontal direction to assemble the golf mat assembly, even if there are gaps among the surface sections of the inclined golf mats adjacent to one another, it is possible to reduce the gaps.
In the inclined golf mat of the present invention, the surface section includes the outermost layer member including the inclined surface and the wedge-shaped intermediate member located on the lower side of the outermost layer member and including the first section to be fit on the lower surface. The second fitting section is provided on the upper surface of the intermediate member. The second section to be fit that fits with the second fitting section is provided on the lower surface of the outermost layer member. Therefore, it is possible to easily assemble the surface section by fitting the second fitting section of the intermediate member and the second section to be fit of the outermost layer member. Therefore, by preparing a plurality of the wedge-shaped intermediate members having angles different from one another and appropriately selecting the intermediate member from the intermediate members, it is possible to give desired inclination to the outermost layer member and the inclined golf mat.
In the inclined golf mat of the present invention, one of the second fitting section and the second section to be fit is projected and the plurality of the other sections are recessed at the predetermined pitch. Therefore, when the outermost layer member is attached to the upper side of the intermediate member, it is possible to optionally adjust an attachment position of the outermost layer member with respect to the intermediate member in units of the pitch of the second fitting sections or the second sections to be fit. As a result, when the plurality of inclined golf mats are coupled in the horizontal direction to assemble the golf mat assembly, even if there are gaps among the outmost layer members of the inclined golf mats adjacent to one another, it is possible to reduce the gaps.
In the inclined golf mat of the present invention, the second section to be fit is configured to fit in not only the second fitting section but also the first fitting section. One of the first fitting section and the second section to be fit is projected in the substantially semispherical shape and the other is recessed in the substantially semispherical shape. Therefore, even if the normal direction of the upper surface of the base and the normal direction of the lower surface of the outermost layer member do not coincide with each other, it is possible to fit the first fitting section of the base and the second section to be fit of the outermost layer member without trouble. As a result, stacking work of three components of the base, the intermediate member, and the outermost layer member is facilitated and assembly work of the inclined golf mat is facilitated.
In the inclined golf mat of the present invention, the bottom-up member is interposed between the base and the surface section. Therefore, it is possible to increase the height from the base to the surface section by the height of the bottom-up member. As a result, when the plurality of inclined golf mats are coupled in the horizontal direction to assemble the golf mat assembly, in coupling sections of the inclined golf mats, it is possible to smoothly continue the supper surfaces of the surface sections including the inclined surfaces.
In the inclined golf mat of the present invention, the bottom-up member includes the plurality of columns and the plate placed on the upper sides of the columns. Therefore, it is possible to configure the bottom-up member in simple structure and inexpensively.
In the inclined golf mat of the present invention, the bottom-up member includes the framework having the substantially rectangular parallelepiped box shape. In the framework, the sixth fitting section that fits with the first section to be fit is provided on the upper surface and the sixth section to be fit that fits with the first fitting section is provided on the lower surface. Therefore, it is possible to realize the light and robust bottom-up member.
In the inclined golf mat of the present invention, the surface section includes the natural turf in the outermost layer. Therefore, by using the inclined golf mat as a shot platform, it is possible to perform practice of shots and putting corresponding to an actual golf course in which natural turf is planted.
With a golf mat assembly of the present invention, it is possible to provide the golf mat assembly composed of the inclined golf mat that achieves the effects explained above.

DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention are explained below.
A first embodiment of the present invention is shown in FIG. 1 to FIG. 9. Note that, in FIG. 1 and FIG. 3, illustration of coupling pieces of bases is omitted. In FIG. 3 (b), illustration of round holes 32 and round holes 42 is omitted.
A golf mat assembly 1 according to the first embodiment is configured by coupling two inclined golf mats 2 in the horizontal direction (the up-down direction in FIG. 1) as shown in FIG. 1. The golf mat assembly 1 assumes a substantially rectangular plate shape having predetermined size (e.g., 120 cm in length, 60 cm in width, and 20 to 50 cm in height).
As shown in FIG. 3 and FIG. 4, each of the inclined golf mats 2 assumes a substantially square plate shape having predetermined size (e.g., 60 cm in length, 60 cm in width, and 20 to 50 cm in height). The inclined golf mat 2 is configured from three components of a base 3, an intermediate member 4, and an outermost layer member 5 in order from the bottom.
As shown in FIG. 4 and FIG. 5, the base 3 includes a board 31 having a substantially square plate shape made of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin). A plurality of (in the first embodiment, nine in three rows and three columns) round holes 32 for reducing the board 31 in weight are formed to pierce through in the up-down direction (a direction perpendicular to the paper surface of FIG. 5). A plurality of (in the first embodiment, sixteen in four rows and four columns) first fitting sections 33 are projected in a substantially semispherical shape over the entire upper surface of the board 31. On the other hand, a plurality of (in the first embodiment, sixteen in four rows and four columns) third sections to be fit 34 are recessed in a substantially semispherical shape in positions corresponding to the plurality of first fitting sections 33 over the entire lower surface of the board 31. Further, a plurality of (in the first embodiment, fifteen) dovetail-shaped coupling pieces 35 having a substantially trapezoidal shape are disposed at predetermined intervals around the board 31.
Note that, in the present invention, the “substantially semispherical shape” includes a complete semispherical shape and shapes approximate to the complete semispherical shape (e.g., a shape of a half of an ellipsoid).
As shown in FIG. 4 and FIG. 6, the intermediate member 4 assumes a wedge shape and includes a main body 41 made of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin). In the main body 41, a plurality of (in the first embodiment, six in two rows and three columns) round holes 42 for reducing the main body 41 in weight are formed to pierce through in the up-down direction (a direction perpendicular to the paper surface of FIG. 6). A plurality of (in the first embodiment, twelve in three rows and four columns) second fitting sections 43 are projected in a substantially semispherical shape on the upper surface of the main body 41. On the other hand, a plurality of (in the first embodiment, twelve in three rows and four columns) first sections to be fit 44 are recessed in a substantially semispherical shape in positions corresponding to the plurality of first fitting sections 33 on the lower surface of the main body 41. The first sections to be fit 44 are configured to fit in the first fitting sections 33 of the base 3.
Further, as shown in FIG. 2, FIG. 4, and FIG. 7, the outermost layer member 5 includes a board 51 having a substantially square plate shape made of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin). On the upper side of the board 51, an artificial turf 53 having a substantially square shape is stuck and integrated via an elastic mat 52 having a substantially square plate shape made of rubber, a urethane material, or the like for shock relief. A plurality of (in the first embodiment, sixteen in four rows and four columns) second sections to be fit 54 are recessed in a substantially semispherical shape on the lower surface of the board 51. The second sections to be fit 54 are configured to fit in the second fitting sections 43 of the intermediate member 4 and the first fitting sections 33 of the base 3. Further, in the outermost layer member 5, as shown in FIG. 1, FIG. 2, and FIGS. 7(b) and 7(c), a plurality of (in the first embodiment, four in two rows and two columns) holes for rubber tee 55 having a stepped round hole shape are formed to piece through the board 51, the elastic mat 52, and the artificial turf 53 in the up-down direction (the left-right direction in FIG. 7(c)). Rubber tees 59 are detachably attached to the holes for rubber tee 55 from below.
When the three components (the base 3, the intermediate member 4, and the outermost layer member 5) are stacked in the up-down direction and the inclined golf mat 2 is assembled, as shown in FIG. 3 and FIG. 4, a planar inclined surface P is formed on the upper surface of the outermost layer member 5.
Note that, in the inclined golf mat 2, the length of the inclined surface P of the outermost layer member 5 projected on a horizontal plane decreases according to an inclination angle of the intermediate member 4. Therefore, when a plurality of (e.g., six in two rows and three columns) inclined golf mats 2 are coupled in the horizontal direction, it is likely that gaps in the horizontal direction are formed among the inclined golf mats 2. However, the gaps are very small and do not hinder practice of shots and putting.
To continuously couple a horizontal golf mat (the horizontal golf mat means a golf mat in which the outermost layer member 5 is stacked on the upper side of the base 3 not via the intermediate member 4) to be adjacent to a side located at a highest level among four sides of the inclined golf mat 2, the base 3 of the horizontal golf mat is set higher according to the inclination angle of the intermediate member 4 of the inclined golf mat 2. Consequently, it is possible to easily realize the continuous coupling of the horizontal golf mat. For example, when the outermost layer member 5 inclines in the longitudinal direction, if the inclination angle of the intermediate member 4 is represented as θ, a value obtained by multiplying the length in the longitudinal direction of the outermost layer member 5 with tan θ is set as an increase in the height of the base 3. In this case, it is likely that the coupling pieces 35 of the base 3 of the horizontal golf mat interfere with the intermediate member 4 of the inclined golf mat 2. However, it is possible to sufficiently avoid such interference by contriving the shape and the size of the coupling pieces 35.
Alternatively, instead of setting the base 3 high in this way, it is also possible to separately prepare a bottom-up member (not shown in the figures) having height corresponding to the inclined angle of the intermediate member 4 of the inclined golf mat 2 and interpose the bottom-up member between the base 3 and the intermediate member 4.
An example of a procedure for laying the golf mat assembly 1 is explained.
First, in a mat preparing step, the inclined golf mats 2 are prepared by a necessary number (e.g., four) according to, for example, breadth of a place (a golf practice range, a yard, a parking lot, etc.) where the golf mat assembly 1 should be laid.
Subsequently, the procedure shifts to a base placing step. The bases 3 of the inclined golf mats 2 are horizontally placed side by side in predetermined arrangement (e.g., two rows and two columns) on the floor. The bases 3 are coupled in the horizontal direction by fitting the coupling pieces 35 of the bases 3 are fit with one another in the bases 3 adjacent to one another.
For example, when the four inclined golf mats 2 are coupled in the horizontal direction in two rows and two columns, as shown in FIG. 8, it is possible to orderly couple the four bases 3 in a matrix shape. As shown in FIG. 9, it is also possible to couple the four bases 3 while slightly shifting two each of the bases 3 in the horizontal direction (the left-right direction in FIG. 9).
Subsequently, the procedure shifts to an intermediate member placing step. The intermediate members 4 are respectively placed on the upper sides of the bases 3. To place the intermediate members 4, the intermediate members 4 are stacked on the upper sides of the bases 3 to fit the first fitting sections 33 on the upper surfaces of the bases 3 and the first sections to be fit 44 on the lower surfaces of the intermediate members 4. Then, the intermediate members 4 are placed on the upper sides of the bases 3.
At this point, in the inclined golf mat 2, as explained above, since the first fitting sections 33 of the base 3 are projected in the substantially semispherical shape and the first sections to be fit 44 of the intermediate member 4 are recessed in the substantially semispherical shape, even if the intermediate member 4 slightly shifts in the horizontal direction with respect to the base 3, it is possible to quickly and easily place the intermediate member 4 in a predetermined position on the upper side of the base 3 in a form of appropriately correcting the shift.
Finally, the procedure shifts to an outermost layer member placing step. The outermost layer members 5 are respectively placed on the upper sides of the intermediate members 4. To place the outermost layer members 5, the outermost layer members 5 are stacked on the upper sides of the intermediate members 4 to fit the second fitting sections 43 on the upper surfaces of the intermediate members 4 and the second sections to be fit 54 on the lower surfaces of the outermost layer members 5. Then, the outermost layer members 5 are placed on the upper sides of the intermediate members 4.
At this point, in the inclined golf mat 2, as explained above, since the second fitting sections 43 of the intermediate member 4 are projected in the substantially semispherical shape and the second sections to be fit 54 of the outermost layer member 5 are recessed in the substantially semispherical shape, even if the outermost layer member 5 slightly shifts in the horizontal direction with respect to the intermediate member 4, it is possible to quickly and easily place the outermost layer member 5 in a predetermined position on the upper side of the intermediate member 4 in a form of appropriately correcting the shift.
Note that, as shown in FIG. 4, one end portion (the left end portion in FIG. 4) of the outermost layer member 5 is in contact with the base 3 not via the wedge-shaped intermediate member 4. The first fitting sections 33 of the base 3 and the second sections to be fit 54 of the outermost layer member 5 fit with each other. At this point, the first fitting sections 33 of the base 3 are projected in the substantially semispherical shape and the second sections to be fit 54 of the outermost layer member 5 are recessed in the substantially semispherical shape. Therefore, even if the normal direction of the upper surface of the base 3 (an arrow N1 direction in FIG. 4) and the normal direction of the lower surface of the outermost layer member 5 (an arrow N2 direction in FIG. 4) do not coincide with each other, the fitting of the first fitting sections 33 of the base 3 and the second sections to be fit 54 of the outermost layer member 5 is performed without problem.
The necessary number of inclined golf mats 2 are coupled in the horizontal direction via the coupling pieces 35 of the bases 3. The laying of the golf mat assembly 1 ends.
When shot practice is performed in the golf mat assembly 1 laid in this way, as shown in FIG. 7(c), a ball B is put on the rubber tee 59 and hit by a golf club (not shown in the figure).
At this point, since the outermost layer member 5 of the inclined golf mat 2 configuring the golf mat assembly 1 includes the inclined surface P, it is possible to perform shot practice corresponding to undulations of an actual golf course. Naturally, it is also possible to perform practice of swings without using the ball B. Note that a golfer may stand on the golf mat assembly 1 or may stand on the outer side of the golf mat assembly 1 according to the preference of the golfer.
The outermost layer member 5 of the inclined golf mat 2 has a structure in which the artificial turf 53 is provided on the upper side of the board 51 made of hard synthetic resin via the elastic mat 52, that is, a material having cushioning properties. Therefore, when the golfer performs practice standing on the golf mat assembly 1, the golfer can perform the practice feeling as if the golfer is standing in a fairway of an actual golf course.
Moreover, the inclined golf mat 2 is simple in structure because the inclined golf mat 2 is easily assembled by fitting the first fitting sections 33 on the upper surface of the base 3 and the first sections to be fit 44 on the lower surface of the intermediate member 4 and fitting the second fitting sections 43 on the upper surface of the intermediate member 4 and the second sections to be fit 54 on the lower surface of the outermost layer member 5. The material of the inclined golf mat 2 is synthetic resin or rubber. Therefore, it is possible to reduce the inclined golf mat 2 in weight compared with the inclined golf mat made of metal in the past. As a result, it is possible to reduce the cost of the inclined golf mat 2 and improve versatility.
The intermediate member 4 and the outermost layer member 5 can be easily assembled by fitting the second fitting sections 43 and the second sections to be fit 54. Therefore, by preparing a plurality of wedge-shaped intermediate members 4 having angles different from one another and appropriately selecting the intermediate member 4 out of the plurality of intermediate members 4, it is possible to give desired inclination to the outermost layer member 5 and the inclined golf mat 2.
Further, in the board 31 of the base 3, as explained above, the first fitting sections 33 are provided on the upper surface and the third sections to be fit 34 are provided on the lower surface. The positions of the first fitting sections 33 and the third sections to be fit 34 correspond to each other. Therefore, when the base 3, the intermediate member 4, and the outermost layer member 5 are stacked in the up-down direction to assemble the inclined golf mat 2, by preparing a plurality of the board 31 in advance, fitting the first fitting sections 33 (which corresponds to the third fitting section of the present invention) of the lower board 31 and the third sections to be fit 34 of theof the upper board 31, and stacking the boards 31 in the up-down direction, it is possible to optionally adjust the height of the outermost layer member 5 (therefore, the height of the inclined golf mat 2). As a result, it is possible to improve extensibility of the inclined golf mat 2.
In the golf mat assembly 1, the plurality of inclined golf mats 2 are coupled in the horizontal direction. Therefore, it is possible to prevent occurrence of a situation in which the inclined golf mats 2 receive a shock involved in shot practice and separate.
A second embodiment of the present invention is shown in FIG. 10.
In the golf mat assembly 1 according to the second embodiment, as shown in FIG. 10, the intermediate member 4 and the outermost layer member 5 of the inclined golf mat 2 are integrated to configure a surface section 6. The inclined surface P of the surface section 6 assumes a curved surface shape.
That is, as shown in FIG. 10, the surface section 6 includes a board 61 made of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin). In the board 61, a lower surface 61 a is formed flat (in a plane shape) and an upper surface 61 b is formed in a wavy shape. The board 61 assumes a substantially square plate shape, the thickness of which gradually increases and decreases. On the upper side of the board 61, an artificial turf 63 is stuck and integrated via an elastic mat 62 made of rubber or a urethane material for shock relief. A plurality of (in the second embodiment, sixteen in four rows and four columns) first sections to be fit 64 are recessed in a substantially semispherical shape on the lower surface of the board 61. The first sections to be fit 64 are configured to fit in the first fitting sections 33 of the base 3. Further, the inclined surface P having a curved surface shape (a wavy shape) is formed on the upper surface of the artificial turf 63.
The other components are basically the same as the components in the first embodiment explained above. Therefore, the same members are denoted by the same reference numerals and signs and explanation of the members is omitted.
Therefore, in the second embodiment, action and effects same as the action and effects in the first embodiment explained above are achieved.
In addition, in the first embodiment, the inclined golf mat 2 is configured from the three components (the base 3, the intermediate member 4, and the outermost layer member 5). On the other hand, in the second embodiment, the inclined golf mat 2 is configured from the two components (the base 3 and the surface section 6). The number of components of the inclined golf mat 2 decreases. Therefore, it is possible to reduce the manufacturing costs of the inclined golf mat 2 and provide the inclined golf mat 2 more inexpensively.
A third embodiment of the present invention is shown in FIG. 11.
In the golf mat assembly 1 according to the third embodiment, as shown in FIG. 11, a hole for cup 56 having a stepped round hole shape is formed to pierce through in the up-down direction substantially in the center of the outermost layer member 5 of the inclined golf mat 2. The configuration of the base 3 and the intermediate member 4 is the same as the configuration in the first embodiment explained above. The round hole 32 of the base 3 and the round hole 42 of the intermediate member 4 are formed in diameters larger than the outer diameter of the hole for cup 56 according to the position of the hole for cup 56. A cup 57 is fit in the hole for cup 56. A drain hole (not shown in the figure) is formed in the bottom of the cup 57. Further, a lid 58 is detachably attached to the cup 57 from the above. The lid 58 is configured from a main body 58 a having a stepped cylindrical shape made of synthetic rubber and a circular artificial turf section 58 b stuck to the upper side of the main body 58 a.
The other components are basically the same as the components in the first embodiment explained above. Therefore, the same members are denoted by the same reference numerals and signs and explanation of the members is omitted.
Therefore, in the third embodiment, action and effects same as the action and effects in the first embodiment explained above are achieved.
In addition, in the third embodiment, normal shot practice can be performed in a state in which the lid 58 is attached to the cup 57. Practice of putting (cup-in) can be performed in a state in which the lid 58 is detached from the cup 57. An upper part of the lid 58 is the artificial turf section 58 b having low density and a lower part of the lid 58 is the main body 58 a having high density. Therefore, the lid 58 is excellent in stability during attachment. Since the drain hole is formed in the bottom of the cup 57, even if the golf mat assembly 1 is used outdoors, it is unlikely that water accumulates in the cup 57. Further, since the round hole 32 of the base 3 and the round hole 42 of the intermediate member 4 are formed in the diameters larger than the outer diameter of the hole for cup 56 according to the position of the hole for cup 56. Therefore, when the cup 57 is fit in the hole for cup 56, it is unlikely that the cup 57 interferes with the base 3 and the intermediate member 4. It is possible to fit the cup 57 in the hole for cup 56 without trouble.
Note that, in the third embodiment, the components other than the components shown in FIG. 11 are the same as the components in the first embodiment. However, the components may be the same as the components in the second embodiment.

On the upper surface of the main body 41, as shown in FIG. 14 (b), fitting regions A2 in sixteen places are formed in a matrix shape of four rows and four columns. In each of the fitting regions A2, twenty-five small second fitting sections 43 are projected at the predetermined pitch P3 in a matrix shape of five rows and five columns. As shown in FIG. 14(c), a large number of small first sections to be fit 44 are recessed at the predetermined pitch P2 over substantially the entire lower surface of the main body 41.
Further, as shown in FIG. 12, the outermost layer member 5 includes the board 51. As shown in FIG. 12(b), a large number of small second sections to be fit 54 are recessed at the predetermined pitch P4 over substantially the entire lower surface of the board 51.
The bottom-up member 7 is configured from sixteen columns 8 and a plate 9 placed on the upper sides of the columns 8. As shown in FIG. 15, each of the columns 8 includes a column main body 81 having a substantially square pole shape. On the upper surface of the column main body 81, as shown in FIGS. 15 (a) and 15(b), twenty-five small fifth fitting sections 82 are projected at a predetermined pitch P5 in a matrix shape of five rows and five columns. On the lower surface of the column main body 81, as shown in FIG. 15(c), twenty-five small fifth sections to be fit 83 are recessed at a predetermined pitch P6 in a matrix shape of five rows and five columns to correspond to the fifth fitting sections 82.
On the other hand, as shown in FIG. 16, the plate 9 includes a plate board 91 having a flat shape. In the plate board 91, a plurality of round holes 94 for reducing the plate board 91 in weight are formed to piece through in the up-down direction (a direction perpendicular to the paper surface of FIG. 16(b)). On the upper surface of the plate board 91, as shown in FIG. 16(b), sixteen fitting regions A3 are formed in a matrix shape of four rows and four columns. In each of the fitting regions A3, twenty-five small fourth fitting sections 92 are projected at a predetermined pitch P7 in a matrix shape of five rows and five columns. As shown in FIG. 16(c), a large number of small fourth sections to be fit 93 are recessed at a predetermined pitch P8 over substantially the entire lower surface of the plate board 91.
Note that, all of the pitch P1 of the first fitting sections 33, the pitch P2 of the first sections to be fit 44, the pitch P6 of the fifth sections to be fit 83, and the pitch P7 of the fourth fitting sections 92 are equal (P1=P2=P6=P7). The pitch P3 of the second fitting sections 43 and the pitch P4 of the second sections to be fit 54 are equal (P3=P4). Further, the pitch P5 of the fifth fitting sections 82 and the pitch P8 of the fourth sections to be fit 93 are equal (P5=P8).
The other components are basically the same as the components in the first embodiment explained above. Therefore, the same members are denoted by the same reference numerals and signs and explanation of the members is omitted.
Therefore, in the fourth embodiment, action and effects same as the action and effects in the first embodiment explained above are achieved.
In addition, in the fourth embodiment, since the bottom-up member 7 is interposed between the base 3 and the intermediate member 4, it is possible to increase the height from the base 3 to the intermediate member 4 by the height of the bottom-up member 7. As a result, when the plurality of inclined golf mats 2 are coupled in the horizontal direction to assemble the golf mat assembly 1, in coupling places of the inclined golf mats 2, it is possible to smoothly continue the upper surfaces of the outermost layer members 5 including the inclined surfaces. Moreover, since the bottom-up member 7 includes the plurality of columns 8 and the plate 9 placed on the upper sides of the columns 8, it is possible to configure the bottom-up member 7 in a simple structure and inexpensively.
In the fourth embodiment, the fourth fitting sections 92 are projected on the upper surface of the plate 9 of the bottom-up member 7 and the plurality of first sections to be fit 44 are recessed at the predetermined pitch P2 on the lower surface of the intermediate member 4. Therefore, when the intermediate member 4 is attached to the upper side of the bottom-up member 7, it is possible to optionally adjust an attachment position of the intermediate member 4 to the bottom-up member 7 in units of the pitch P2 of the first sections to be fit 44. As a result, when the plurality of inclined golf mats 2 are coupled in the horizontal direction to assemble the golf mat assembly 1, even if there are gaps among the outermost layer members 5 of the inclined golf mats 2 adjacent to one another, it is possible to reduce the gaps.
Further, in the fourth embodiment, the second fitting sections 43 are projected on the upper surface of the intermediate member 4 and the plurality of second sections to be fit 54 are recessed at the predetermined pitch P4 on the lower surface of the outermost layer member 5. Therefore, when the outermost layer member 5 is attached to the upper side of the intermediate member 4, it is possible to optionally adjust an attachment position of the outermost layer member 5 to the intermediate member 4 in units of the pitch P4 of the second sections to be fit 54. As a result, when the plurality of inclined golf mats 2 are coupled in the horizontal direction to assemble the golf mat assembly 1, even if there are gaps among the outermost layer members 5 of the inclined golf mats 2 adjacent to one another, it is possible to reduce the gaps.
Note that, in the fourth embodiment, the components other than the components shown in FIG. 12 to FIG. 16 are the same as the components in the first embodiment. However, the components other than the components shown in FIG. 12 to FIG. 16 may be the same as the components in the second or third embodiment or may be the same as components obtained by optionally combining the components explained in the second embodiment and the components explained in the third embodiment.
A fifth embodiment of the present invention is shown in FIG. 17.
In the golf mat assembly 1 according to the fifth embodiment, as shown in FIG. 17, in the bottom-up member 7 of the inclined golf mat 2, pluralities of (in the fifth embodiment, four, seven, and ten) columnar horizontal coupling members 10 made of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin) are integrally attached to pluralities of (in the fifth embodiment, four, six, and eight) columns 8 in a form of coupling the columns 8 in the horizontal direction. Consequently, a plurality of (in the fifth embodiment, five) coupling columns 11 composed of the columns 8 and the horizontal coupling members 10 are configured.
The other components are basically the same as the components in the fourth embodiment explained above. Therefore, the same members are denoted by the same reference numerals and signs and explanation of the members is omitted.
Therefore, in the fifth embodiment, action and effects same as the action and effects in the fourth embodiment explained above are achieved.
In addition, in the fifth embodiment, as explained above, the pluralities of columns 8 configuring the bottom-up member 7 are coupled by the pluralities of horizontal coupling members 10. Therefore, stability (setting) of the columns 8 is considerably improved. As a result, it is possible to prevent occurrence of a situation in which the columns 8 are broken while the golfer repeats practice of shots in the golf mat assembly 1.
Note that, in the fifth embodiment, the components other than the components shown in FIG. 17 may be the same as the components in any one of the first to third embodiments or may be the same as components obtained by optionally combining the components explained in the first to third embodiments. Further, the bottom-up member 7 according to the fifth embodiment and the bottom-up member 7 in the configuration according to the fourth embodiment (see FIG. 12 to FIG. 16) may be used in combination.
A sixth embodiment of the present invention is shown in FIG. 18 and FIG. 19.
In the golf mat assembly 1 according to the sixth embodiment, as shown in FIG. 18 and FIG. 19, four bases 3 are coupled in the horizontal direction in two rows and two columns. Six outermost layer members 5 (5A and 5B) are detachably attached to the upper sides of the bases 3.
Two outermost layer members 5 (the outermost layer members 5A located on the left side in FIG. 18) among the six outermost layer members 5 are formed in size substantially the same as the size of the bases 3. The remaining four outermost layer members 5 (inclined golf mats 5A and 5B located on the right side of FIG. 18) are formed in a half size of the size of the bases 3. Five outermost layer members 5A among the six outermost layer members 5 include the artificial turfs 53 in the outermost layers as in the first embodiment explained above. On the other hand, the remaining one outermost layer member 5B includes a natural turf 50 in an outermost layer.
The other components are basically the same as the components in the first embodiment explained above. Therefore, the same members are denoted by the same reference numerals and signs and explanation of the members is omitted.
Therefore, in the sixth embodiment, action and effects same as the action and effects in the first embodiment explained above are achieved.
In addition, in the sixth embodiment, as explained above, the outermost layer member 5B includes the natural turf 50 in the outermost layer. Therefore, by using the outermost layer member 5B as a shot platform (putting a ball on the outermost layer member 5B and hitting the ball), it is possible to perform practice of shots and putting corresponding to an actual golf course in which natural turf is planted.
In the sixth embodiment, as explained above, a part of the sixth outermost layer members 5 is formed in the half size of the size of the remaining part. Therefore, it is possible to finely set undulations of the entire golf mat assembly 1. It is possible to perform practice of shots and putting in various situations. For example, it is possible to perform shot practice not only in stances such as toe raised, toe lowered, left foot raised, and left foot lowered stances but also in a condition in which the left and the right of a stance are different. It is also possible to adjust a condition different from inclination of a stance by dividing a shot platform into small parts and inclining the divided small parts.
Note that, in the sixth embodiment, the components other than the components shown in FIG. 18 and FIG. 19 are the same as the components in the first embodiment. However, the components other than the components shown in FIG. 18 and FIG. 19 may be the same as the components in the second or third embodiment. Further, the components other than the components shown in FIG. 18 and FIG. 19 may be the same as components obtained by optionally combining a part or all of the components explained in the second to fifth embodiments.
A seventh embodiment of the present invention is shown in FIG. 20 to FIG. 23.
In the golf mat assembly 1 according to the seventh embodiment, as shown in FIG. 20 to FIG. 22, the bottom-up member 7 of the inclined golf mat 2 is configured from an integrated object having a rectangular parallelepiped box shape. The other components are basically the same as the components in the fourth embodiment explained above.
That is, the bottom-up member 7 includes a framework 71 formed of hard synthetic resin (e.g., polystyrene, polycarbonate, or ABS resin) in a substantially rectangular parallelepiped (regular hexahedron) box shape. The framework 71 is configured from six surfaces of an upper surface 71 a, a bottom surface 71 b, a front surface 71 c, a rear surface 71 d, a left side surface 71 e, and a right side surface 71 f.
On an upper surface 71 a of the framework 71, as shown in FIG. 21, fitting regions A4 in six places are formed in a matrix shape of two rows and three columns. In each of the fitting regions A4, nine small sixth fitting sections 73 are projected at a predetermined pitch in a matrix shape of three rows and three columns. The sixth fitting sections 73 are configured to fit in the first sections to be fit 44 of the intermediate member 4. Further, on the upper surface 71 a, one or more (in the seventh embodiment, three) round holes 72 for reducing the framework 71 in weight are formed to pierce through in the up-down direction (the up-down direction in FIG. 20).
On a bottom surface 71 b of the framework 71, as shown in FIG. 22, regions to be fit A5 in six places are formed in a matrix shape of two rows and three columns. In each of the regions to be fit A5, sixty-four cylindrical sixth sections to be fit 74 are projected at a predetermined pitch in a matrix shape of eight rows and eight columns. The sixth sections to be fit 74 are configured such that, as shown in FIG. 23, the first fitting sections 33 of the base 3 are fit in gaps of the four sixth sections to be fit 74 and the sixth sections to be fit 74 are elastically slightly recessed to firmly fit the first fitting sections 33 and the sixth sections to be fit 74.
On a front surface 71 c of the framework 71, as shown in FIG. 20 to FIG. 22, one or more (in the seventh embodiment, three) square holes 75 for reducing the framework 71 in weight are formed to pierce through in the horizontal direction (a direction perpendicular to the paper surface of FIG. 20). On a rear surface 71 d of the framework 71, one or more (in the seventh embodiment, three) square holes 76 for reducing the framework 71 in weight are formed to pierce through in the horizontal direction (the direction perpendicular to the paper surface of FIG. 20) in positions opposed to the square holes 75. On a left side surface 71 e of the framework 71, as shown in FIG. 21, one or more (in the seventh embodiment, one) square holes 77 for reducing the framework 71 in weight are formed to piece through in the horizontal direction (the left-right direction in FIG. 20). On a right side surface 71 f of the framework 71, one or more (in the seventh embodiment, one) square holes 78 for reducing the framework 71 in weight are formed to pierce through in the horizontal direction (the left-right direction in FIG. 20) in positions opposed to the square holes 77.
Further, on the inside of the framework 71, as shown in FIG. 21 and FIG. 22, reinforcing ribs 79 are formed integrally with the framework 71 along the inner peripheral surface of the framework 71.
Therefore, in the seventh embodiment, action and effects same as the action and effects in the fourth embodiment explained above are achieved.
In addition, in the seventh embodiment, as explained above, since the bottom-up member 7 is the integral object having the rectangular parallelepiped box shape, the bottom-up member 7 is light and robust. It is possible to prevent occurrence of a situation in which the bottom-up member 7 is broken while the golfer repeats practice of shots in the golf mat assembly 1.
In the seventh embodiment, the first fitting sections 33 of the base 3 and the sixth sections to be fit 74 of the bottom-up member 7 firmly fit with each other. Therefore, even if the golfer repeats practice of shots in the golf mat assembly 1, the bottom-up member 7 does not easily come off the base 3.
Note that, in the seventh embodiment, the components other than the components shown in FIG. 20 to FIG. 23 may be the same as the components in any one of the first to third embodiments. The components other than the components shown in FIG. 20 to FIG. 23 may be the same as components obtained by optionally combining a part or all of the components explained in the first to sixth embodiments.
Note that, in the first and third to sixth embodiments explained above, the inclined golf mat 2 is explained in which the first fitting sections 33 of the base 3 are projected and the first sections to be fit 44 of the intermediate member 4 are recessed. However, the recess and the projection may be reversed to recess the first fitting sections 33 of the base 3 and project the first sections to be fit 44 of the intermediate member 4.
In the first and third to sixth embodiments explained above, the inclined golf mat 2 is explained in which the second fitting sections 43 of the intermediate member 4 are projected and the second sections to be fit 54 of the outermost layer member 5 are recessed. However, the recess and the projection may be reversed to recess the second fitting sections 43 of the intermediate member 4 and project the second sections to be fit 54 of the outermost layer member 5.
In the first and third to sixth embodiments explained above, the inclined golf mat 2 is explained in which the inclined surface P of the outermost layer member 5 inclines in the direction along one side of the inclined golf mat 2 (the left-right direction in FIG. 4). However, an inclining direction of the inclined surface P is not particularly limited. For example, the inclined surface P may incline in a direction along a side perpendicular to the one side of the inclined golf mat 2 (a direction perpendicular to the paper surface of FIG. 4). The inclined surface P may incline in a diagonal line direction of the inclined golf mat 2.
In the second embodiment explained above, the inclined golf mat 2 is explained in which the inclined surface P of the surface section 6 inclines in the direction along one side of the inclined golf mat 2 (the left-right direction in FIG. 10). However, an inclining direction of the inclined surface P is not particularly limited. For example, the inclined surface P may incline in a direction along a side perpendicular to the one side of the inclined golf mat 2 (a direction perpendicular to the paper surface of FIG. 10). The inclined surface P may incline in the diagonal line direction of the inclined golf mat 2.
In the first and third to sixth embodiments explained above, the inclined golf mat 2 is explained in which the first fitting sections 33 of the base 3 and the first sections to be fit 44 of the intermediate member 4 have the substantially semispherical shape. However, the first fitting sections 33 and the first sections to be fit 44 may have a shape other than the substantially semispherical shape (e.g., a conical shape or a pyramid shape) as long as the first fitting sections 33 and the first sections to be fit 44 fit with each other. The inclined golf mat 2 is explained in which the second fitting sections 43 of the intermediate member 4 and the second sections to be fit 54 of the outermost layer member 5 have the substantially semispherical shape. However, the second fitting sections 43 and the second sections to be fit 54 may have a shape other than the substantially semispherical shape (e.g., a conical shape or a pyramid shape) as long as the second fitting sections 43 and the second sections to be fit 54 fit with each other.
In the second embodiment explained above, the inclined golf mat 2 is explained in which the first fitting sections 33 of the base 3 and the first sections to be fit 64 of the surface section 6 have the substantially semispherical shape. However, the first fitting sections 33 and the first sections to be fit 64 may have a shape other than the substantially semispherical shape (e.g., a conical shape or a pyramid shape) as long as the first fitting sections 33 and the first sections to be fit 64 fit with each other.
In the first and third to sixth embodiments explained above, the inclined golf mat 2 is explained in which the inclined surface P of the outermost layer member 5 has the planar shape. However, the inclined surface P may have a curved surface shape.
In the second embodiment explained above, the inclined golf mat 2 is explained in which the inclined surface P of the surface section 6 has the curved surface shape. However, the inclined surface P may have a planar shape.
In the first and third to fifth embodiments explained above, one intermediate member 4 is inserted between the base 3 and the outermost layer member 5. However, a plurality of (two or more) intermediate members 4 can be inserted. In this case, it is possible to realize the inclined surface P that inclines steeply or change an inclining direction of the inclined surface P.
In the first to sixth embodiments explained above, the four holes for rubber tee 55 are formed in the outermost layer member 5 of the inclined golf mat 2. However, the number of holes for rubber tee 55 is not limited to four. For example, the number may be six. Alternatively, instead of the holes for rubber tee 55, hollows (not shown in the figure) for ball placing can also be formed on the upper surface of the outermost layer member 5 (the surface section 6). In this case, even if the outermost layer member 5 of the inclined golf mat 2 inclines, by placing the ball B on the hollows for ball placing, it is possible to perform shot practice without trouble.
In the first and third to fifth embodiments explained above, the outermost layer member 5 of the inclined golf mat 2 is the outermost layer member of the three layer structure composed of the board 51, the elastic mat 52, and the artificial turf 53. However, the structure of the outermost layer member 5 is not limited to such a three layer structure and may be, for example, a two layer structure composed of the elastic mat 52 and the artificial turf 53.
In the first, third, and sixth embodiments explained above, the inclined golf mat 2 including the artificial turf 53 in the outermost layer is explained. In the second embodiment explained above, the inclined golf mat 2 including the artificial turf 63 in the outermost layer of the surface section 6 is explained. However, naturally, various raised materials (not shown in the figures) can also be used instead of the artificial turfs 53 and 63.
In the first to sixth embodiments explained above, the base 3 made of the hard synthetic resin is explained. However, the material of the base 3 is not limited to the hard synthetic resin. For example, a mat made of rubber and a floor material made of wood can also be used as the base 3.
In the first to sixth embodiments explained above, the coupling pieces 35 for coupling, in the horizontal direction, the plurality of inclined golf mats 2 configuring the golf mat assembly 1 are provided in the base 3. However, depending on a setting state of the inclined golf mats 2 and other conditions, the coupling pieces 35 can be omitted. For example, when the base 3 is a mat made of rubber or a carpet and a coefficient of friction of the base 3 with respect to a floor on which the base 3 is placed is large or when the size of the inclined golf mats 2 is large (e.g., 90 cm in length and 90 cm in width), a frictional force between the floor on which the base 3 is placed and the base 3 increases. Therefore, it is considered that it is not always necessary to couple the plurality of inclined golf mats 2 via the coupling pieces 35.
In the third embodiment explained above, the inclined golf mat 2 is explained in which the hole for cup 56 is formed substantially in the center of the outermost layer member 5. However, the position of the hole for cup 56 is not limited to substantially the center of the outermost layer member 5. For example, the position of the hole for cup 56 may be the vicinity of a corner portion of the outermost layer member 5. Further, the number of holes for cup 56 is not limited to one and may be plural (two or more).
In the fourth and fifth embodiments explained above, the inclined golf mat 2 is explained in which the first fitting sections 33 are provided only in the fitting region A1 of the base 3, the second fitting sections 43 are provided only in the fitting region A2 of the intermediate member 4, and the fourth fitting sections 92 are provided only in the fitting region A3 of the plate 9. However, the first fitting sections 33 may be provided over the entire upper surface of the board 31 excluding the round holes 32. The second fitting sections 43 may be provided over the entire upper surface of the main body 41 excluding the round hole 42. Further, the fourth fitting sections 92 may be provided over the entire upper surface of the plate board 91 excluding the round holes 94.
In the fifth embodiment explained above, the coupling column 11 is explained in which the four, six, and eight columns 8 are coupled by the horizontal coupling members 10. However, the numbers of the columns 8 coupled by the horizontal coupling members 10 are not limited to four, six, and eight.
In the sixth embodiment explained above, only one outermost layer member 5B among the six outermost layer members 5 includes the natural turf 50 in the outermost layer. However, it is also possible to prepare various kinds of conditions such as a condition for a fairway and a condition for rough by appropriately increasing and decreasing the number of outermost layer members 5 including the natural turfs 50 in the outermost layers.
In the first to third embodiments explained above, the golf mat assembly 1 is configured by coupling the two inclined golf mats 2 in the horizontal direction. In the fourth and fifth embodiments explained above, the golf mat assembly 1 is configured by coupling the three inclined golf mats 2 in the horizontal direction. However, the number of inclined golf mats 2 configuring the golf mat assembly 1 is not limited to two and three and may be one or four or more.
Further, in the sixth embodiment explained above, the golf mat assembly 1 including the four bases 3 and the six outermost layer members 5 is explained. However, the numbers of the bases 3 and the outermost layer members 5 are not particularly limited.
In the seventh embodiments explained above, the inclined golf mat 2 including the bottom-up member 7 including the framework 71 having the substantially rectangular parallelepiped box shape is explained. However, it is also possible to vertically providing partition plates for reinforcement (not shown in the figures) at appropriate intervals on the inside of the framework 71 of the bottom-up member 7 and reinforce the bottom-up member 7 according to strength requested to the bottom-up member 7.
In the seventh embodiment explained above, the inclined golf mat 2 is explained that is provided with a fitting mechanism (see FIG. 23) in which the first fitting sections 33 of the base 3 fit in the gaps of the four sixth sections to be fit 74 of the bottom-up member 7 and the sixth sections to be fit 74 are elastically slightly recessed to firmly fit the first fitting sections 33 and the sixth sections to be fit 74. However, naturally, such a fitting mechanism can also be applied to fitting of the bottom-up member 7 and the intermediate member 4 or fitting of the intermediate member 4 and the outermost layer member 5.
The present invention can be applied when a golfer performs practice of shots and putting of golf in, besides an outdoor or indoor golf practice range, a yard or a parking lot in a home of the golfer and the like.
