Description

GOLF PRACTICE MAT FOR SEVEN DIBOT FORMATION

The present invention relates to a golf practice mat, and more particularly, to practice the swing of the correct track, to mitigate the impact transmitted to the user's body, and relates to a golf practice mat having significantly improved durability and reusability .

Golf driving ranges are typically equipped with multiple golf mats for practice in field-like conditions. Therefore, golfers can practice a variety of shots, such as drive shots, iron shots, wood shots put a golf ball on the golf mat.

However, since the shot is used directly on the golf mat or in a state where a golf ball is placed on a tee, a shock is frequently applied to the golf mat. That is, when the golfer swings according to a standard swing track while practicing iron shots, a divot may be formed. When the golf mat hits the golf mat strongly with a swing track where the divot may be formed at the golf driving range Injuries to the wrists, elbows, ribs, waist, knees, or muscles and ligaments are damaged.

Conventionally, in order to solve such a problem, a method including a sponge layer, a rubber layer, or a spring for absorbing an impact on a golf mat has been used.

First, the golf mat provided with the sponge layer was able to obtain an effect that the impact transmitted to the wrist is partially reduced. Since the sponge layer should be provided between the bottom plate seated on the bottom surface and the artificial turf layer, a separate adhesive must be used to bond the sponge layer. However, if the golf mat is used for a long time, the adhesive force is relatively lowered, causing the artificial turf layer to fall off from the sponge layer. As such, when the sponge layer and the artificial turf layer fall, an operator has to inconvenience the sponge layer by using an adhesive. In addition, since the sponge layer is not generally high in rigidity, a part of the sponge layer may fall off when used for a long time. As such, when the sponge layer is separated and partially dropped, there is a problem in that the shock absorbing power of the sponge layer is weakened and the appearance is not good.

In addition, the golf mat equipped with a rubber layer can absorb a part of the impact caused by the golf club, but considering the impact that a user who needs a lot of practice does not have enough shock absorbing function, it can harden at low temperature. Have

In addition, the golf mat is provided with a spring can minimize the pain felt through the user's wrist by absorbing the impact of the golf club, but the durability is difficult to use for a long time as well as the complex structure is manufactured Has a difficult disadvantage.

In addition, recently, technologies using latex and the like have been developed as a shock absorber provided between the bottom plate and the artificial turf layer.

As one example, Korean Patent Laid-Open Publication No. 2009-0081963 (published on July 29, 2009) includes a bottom plate seated on a bottom surface, a latex layer bonded to an upper surface of the bottom plate, and made of latex, and It comprises an artificial turf adhered to form an integral part with the latex layer, the latex layer is formed through a plurality of shrinkage holes penetrated up and down, the shrinkage hole is characterized in that it has a constant interval in the longitudinal direction and the width direction A technique for golf mats is disclosed.

However, the golf mat can absorb the impact of the golf club to minimize the pain felt by the user's wrist, but if the golf club hits the surface of the mat, the golf club head is recessed beyond the proper depth to have the correct swing track Swing practice is difficult.

In addition, when the golf mat is exposed to high or low temperatures or exposed to direct sunlight, the latex is hardened and damaged, and latex having an appropriate level of stiffness and elasticity is expensive. Is generated.

Thus, since the conventional golf mat is not suitable for practicing the swing track to form the divot, there is a need for the development of a new golf practice mat for practicing the correct swing track to form the divot.

Accordingly, an object of the present invention is to not only reduce the shock transmitted to the body when hitting directly with the golf club, but also to practice swinging to have a correct swing trajectory to form a bot by providing a constant repulsive force, and summer and winter Likewise, it can be used regardless of the external environment, and provides a golf practice mat with improved durability and reusability for long-term use.

1 and 2, the golf practice mat according to an embodiment of the present invention is attached to the bottom plate 10 and the top of the bottom plate 10 and the insertion groove 22 is seated on the bottom surface. The fixed plate 20, the first shock absorbing layer 30 inserted into the fitting insertion groove 22 and seated on the top of the bottom plate 10, and the first impact absorbing layer 30 inserted into the fitting insertion groove 22. The second shock absorbing layer 40 is mounted on the upper portion of the absorbing layer 30, and the artificial turf layer 50 is attached to the top of the fixing plate 20 and the second shock absorbing layer 40.

Hereinafter, each component will be described in more detail with reference to the drawings.

1 and 2, the golf practice mat according to an embodiment of the present invention includes a bottom plate (10).

The bottom plate 10 is to be seated on the bottom surface, it is preferably formed to have a thickness of about 3mm in the shape of a rectangular parallelepiped.

As shown in FIG. 2, the bottom plate 10 is provided with a plurality of through holes 12. The through groove 12 is a shock is transmitted to the first shock absorbing layer 30 to receive the air present in the interior of the first shock absorbing layer 30 when the first shock absorbing layer 30 is compressed by the impact. Provide space for Since the through grooves 12 are formed, air existing in the first shock absorbing layer 30 may be discharged to smoothly compress the first shock absorbing layer 30, thereby preventing the shock transmitted from the outside. It can be effectively absorbed. In addition, when the shock transmitted to the first shock absorbing layer 30 disappears, air may be provided to restore the first shock absorbing layer 30 through the through groove 12.

To this end, the through holes 12 are formed to penetrate the bottom plate 10 in the vertical direction, and a plurality of the through plates 12 are disposed at regular intervals in the longitudinal direction and the width direction of the bottom plate 10. In addition, the through groove 12 may be formed to have a diameter of 20 to 30mm. At this time, the through groove 12 may be formed using a perforator.

The bottom plate 10 may be formed of rubber, preferably raw rubber, or the like to provide support to the components seated thereon in a state in which a plurality of through holes 12 are formed therein.

1 and 2, the golf practice mat according to an embodiment of the present invention includes a fixing plate 20.

The fixing plate 20 is attached to the top of the bottom plate 10, the fitting insertion groove 22 is formed so that the shock absorbing layer (30, 40) for absorbing the impact of the golf club can be fitted.

More specifically, the fixing plate 20 is formed to have a thickness of 10 to 20 mm in the shape of a rectangular parallelepiped, and the fitting insertion groove 22 has a rectangular parallelepiped having a length and width smaller than that of the fixing plate 20 in the fixing plate 20. It is formed to have the same thickness in shape. At this time, the fixing plate 20 and the bottom plate 10 are attached to each other using an adhesive or the like.

The fitting insertion groove 22 may be formed in a structure in which a part of the fixing plate 20 is not damaged even when the shock transmitted to the shock absorbing layers 30 and 40 through the golf club is transmitted to the fixing plate 20 according to the swing trajectory of the golf club. Can be. To this end, the insertion groove 22 may be formed in a form in which one side of the fixing plate 20 is open as shown in FIG. 3. In other words, in the case where the insertion groove 22 is formed as shown in FIG. 2, when the external force acts on the shock absorbing layers 30 and 40, the pressure acts on the left side of the shock absorbing layers 30 and 40. The left part can be ruptured by the pressure. However, in the case where the insertion groove 22 is formed as shown in FIG. 3, even when pressure acts on the left side of the shock absorbing layers 30 and 40, the left side of the shock absorbing layers 30 and 40 is opened, so that the pressure is external. It is diverted to the fixing plate 20 does not generate a portion ruptured by the impact absorbing layer (30, 40).

As such, the fitting insertion groove 22 formed in one side of the fixing plate 20 is opened to remove the obstacle (the left part of the fixing plate) that obstructs the correct swing trajectory of the golf club, thereby smoothly swinging the golf club. It acts as an outlet for pressure to approximate the hand, as in lawns.

On the other hand, the fixed plate 20 impacts the golf club to absorb the impact to reduce the repulsive force transmitted to the user of the golf club even when hitting the artificial turf layer 50 is not provided with the second shock absorbing layer 40 Rubber, etc., which are absorbent materials. At this time, since the fixing plate 20 is provided to reduce the production cost, it is preferable to use a molded material made of waste tire powder or the like, which is relatively inexpensive and can recycle resources.

2 and 3, the golf practice mat according to an embodiment of the present invention includes a first shock absorbing layer (30).

The first shock absorbing layer 30 is to be seated on the top of the bottom plate 10 in a state of being inserted into the insertion groove 22, it is composed of a memory foam to absorb the impact of the golf club. In this case, the memory foam is preferably formed of a urethane material, but is not limited thereto.

More specifically, the first shock absorbing layer 30 has a density of 50.2 to 56.2 kg / m 2, an elongation of 87 to 93%, and a compressive hardness of 25 to 4.2 kg / 314 to protect the user's wrist. It is preferable to use a memory foam having a cm 3 and a tensile strength of 0.82 to 1.42 kg / cm 2. In addition, the first impact absorbing layer 30 is 8 to 12% under permanent compression shrinkage of 70 ?, 22hrs, 50% def condition, it is preferable to use a memory foam having a tear strength of 0.4 to 0.7 kg / ㎝. .

The first shock absorbing layer 30 is preferably used to be molded in accordance with the size of the insertion groove 22 to be inserted into the insertion groove 22 to be attached to the upper surface of the bottom plate (10). For example, the first shock absorbing layer 30 may be formed to have a thickness of 7 to 19 mm in the shape of a rectangular parallelepiped having the same length and width as the fitting insertion groove 22.

As shown in FIG. 4, the first shock absorbing layer 30 is compressed while discharging air existing therein into the through groove 12 of the bottom plate 10 when the golf club is hit, thereby absorbing the shock. In addition, the compressed memory foam is restored while absorbing air present in the through groove 12 of the bottom plate 10.

On the other hand, the first shock absorbing layer 30 made of a memory foam can be cured when the temperature is lowered, as in the conventional shock absorbing layer made of a latex material or a rubber material. However, since the first shock absorbing layer 30 is formed of a memory foam, if it is pressed several to tens of times before the swing practice, the first shock absorbing layer 30 is restored to the state before curing. In this way, the golf practice mat according to the present invention, even though the memory foam is a shock-absorbing material is cured at a low temperature, the function is restored by a simple operation, it can be used even in winter.

2 and 3, the golf practice mat according to an embodiment of the present invention includes a second shock absorbing layer 40.

The second shock absorbing layer 40 is to be seated on the upper portion of the first shock absorbing layer 30 in a state of being inserted into the insertion groove 22, so that the golf club is not recessed into the memory foam during the swing practice by the user. It is composed of a rubber sponge to provide a repulsive force to the golf club. As described above, the present invention can absorb most of the impact generated from the golf club through the first shock absorbing layer 30, but the second shock absorbing layer 40 cannot be controlled only by the first shock absorbing layer 30. This is to be provided. In addition, the second shock absorbing layer 40 serves to prevent the first shock absorbing layer 30 from being damaged by reducing the shock transmitted to the first shock absorbing layer 30. In other words, if only the memory foam is used as the shock absorbing material, the memory foam can be easily damaged by the impact of the golf club. However, the present invention uses the memory foam and the rubber sponge as the shock absorbing material, so that the memory foam is directly exposed to the impact. This can prevent damage.

Specifically, the second shock absorbing layer 40 may be formed of any one of ethylene vinyl acetate (Ethylene vinyl acetate: EVA) sponge, chloroprene rubber (CR) sponge, and ethylene propylene rubber (Ethylene Propylene Diene Monomer: EPDM) sponge. Can be. In a particular embodiment, the second shock absorbing layer 40 according to the present invention has a density of 0.046 to 0.18 kg / cm 3 and a hardness of 14 to 45 kg / 314 to protect the first shock absorbing layer 30 and to provide a suitable repulsive force. It is preferable to use a rubber sponge having a cm 3 and a tensile strength of 0.85 to 5.4 kg / m 2.

In addition, the second shock absorbing layer 40 may be formed in a pyramidal shape, a profile egg plate shape, or a perforated plate shape.

In addition, the second shock absorbing layer 40 is preferably molded and used to fit the size of the fitting insertion groove 22 so that the first shock absorbing layer 30 can be inserted into the fitting insertion groove 22. For example, the second shock absorbing layer 40 may be formed to have a thickness of 2 to 9 mm in a rectangular parallelepiped shape having the same length and the same width as the first shock absorbing layer 30.

As described above, since the second shock absorbing layer 40 is in contact with the first shock absorbing layer 30 without being attached to the first shock absorbing layer 30, the second shock absorbing layer 40 and the first shock absorbing layer 40 may act even when an impact caused by the golf club is applied. The tear between the contact surfaces between the shock absorbing layer 30 does not occur. As such, the present invention has an advantage that it can be used for a long time than the existing golf practice mat because it is formed in a structure that minimizes internal damage.

1 to 3, the golf practice mat according to the present invention includes an artificial turf layer 50.

The artificial turf layer 50 is provided to provide a feeling of natural grass in the golf course, and is attached to the top of the fixing plate 20 and the second shock absorbing layer 40. At this time, the fixing plate 20 and the artificial turf layer 50 and the second shock absorbing layer 40 and the artificial turf layer 50 are bonded to each other through an adhesive or the like and are not separated from each other even after long-term use.

In a particular aspect, artificial turf layer 50 according to the present invention is composed of a mesh layer (not shown) and artificial grass (not shown) bonded with an adhesive to the mesh layer, to transfer the grass-like effect to the golfer It is.

The mesh layer has a lattice spacing of 0.1 to 2 mm, a thickness of 0.5 to 1.5 mm, and may be made of polyester, nylon, polypropylene, or the like. .

The artificial turf is composed of nylon (nylon), polypropylene (polypropylene), polyethylene (polyethylene) or polyvinylidene chloride (polyvinylidene chloride), depending on the conditions of use to selectively use the height of 12mm to 17mm in the field Can express effects In addition, the woven structure of the artificial turf may be made of raschel, straight hair, or a mixed structure thereof.

On the other hand, the artificial turf layer 50 is provided with a curved surface on the fixing plate 20 and the second shock absorbing layer 40, as shown in Figure 4 is not easily broken by the impact of the golf club. In other words, the artificial turf layer 50 is provided so that the tension is not maintained, so that even when the golf club strikes a portion, the portion of the artificial turf may absorb a portion of the impact while the portion is moved, thereby preventing the tearing problem.

To this end, the thickness of the fixing plate 20 is greater than the thickness of the first shock absorbing layer 30, the thickness of the fixing plate 20 is the thickness of the first shock absorbing layer 30 and the second shock absorbing layer 40. It is formed smaller than the combined value. That is, since the combined height of the first shock absorbing layer 30 and the second shock absorbing layer 40 is higher than the height of the fixing plate 20, the artificial turf layer 50 positioned on the second shock absorbing layer 40 is fixed plate. It is located at a position higher than the artificial turf layer 50 located on the upper portion of the 20.

5 is a state diagram showing a swing impact according to an embodiment of the present invention.

As shown in FIG. 5, the golf practice mat according to the present invention smoothly forms a bot (B) when the user exercises a strike with a correct swing track through a golf ball disposed on the artificial turf layer 50. This gives the user a feeling similar to the feeling felt when a divot is formed in natural grass. That is, the present invention can sufficiently absorb the impact of the golf club through the first shock absorbing layer 30, and provides a repulsive force similar to the golf course through the second shock absorbing layer 40 to form a correct swing track (divivo swinging) It is possible to practice swing to have a track.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 6 to 15.

As shown in FIG. 6, at least one air discharge path 13 is formed in the bottom plate 10 independently of the plurality of through holes 12. The air discharge path 13 may pass through at least one or more of the through holes 12, but may not pass through any one of the through holes 12. The open discharge path may be formed only in the horizontal direction of the bottom plate 10, only in the vertical direction, or may be formed in both the horizontal and vertical directions. In this case, as shown in FIG. 6, the air discharge passage 13 may be formed by connecting the through grooves 12, and the air discharge passage 13 formed in this manner may include a first shock absorbing layer ( The shock is transmitted to 30 to provide a space and a passage through which air existing in the first shock absorbing layer 30 is introduced and discharged when the first shock absorbing layer 30 is compressed by the shock. Since the air discharge path 13 is formed, air existing in the first shock absorbing layer 30 can be easily discharged, and the first shock absorbing layer 30 can be smoothly compressed, thereby transmitting from the outside. It is possible to effectively absorb the impact. In addition, when the shock transmitted to the first shock absorbing layer 30 disappears, air may be provided to restore the first shock absorbing layer 30 through the through groove 12.

Meanwhile, as shown in FIG. 7, the air discharge path 13 may also be formed in the second shock absorbing layer 40 of the present invention. The air discharge passage 13 formed in the second shock absorbing layer 40 includes an air discharge passage 13 in a horizontal direction, an air discharge passage 13 in a vertical direction, an air discharge passage 13 in a diagonal direction, and an arbitrary direction. One or more of the open discharge path of the straight or curved form of may be formed. On the other hand, the air discharge path 13 of Figure 7 is characterized in that the width of the air discharge path 13 is not always the same depending on the position of the second shock absorbing layer (40). The dibots formed during swinging of the golf club are generally not evenly formed at all positions of the second shock absorbing layer 40. The location where the divot is mainly generated may be the most central part of the second shock absorbing layer 40 among the virtual spaces created by the extension lines of the user's toes. In some cases, the location of the divot is close to the toes or far from both toes. There can be a lot of dibots on the side. Therefore, it is necessary to adjust the width of the air discharge passage 13 in response to the position where a large number of divots occur. The moment the divot occurs during the swing, the impact pressure of the first shock absorbing layer 30 is transmitted to the second shock absorbing layer 40. At this time, the pressure of the air suddenly increases around the site where the divot is formed. Therefore, in the corresponding portion of the second shock absorbing layer 40 at the position where the divot is expected to be formed frequently, the width or depth of the air discharge passage 13 needs to be relatively wider or deeper than other portions. If only the compressed air of the portion where the divot is formed in the second shock absorbing layer 40 is quickly discharged in all directions, the compressed air may be easily diffused in all directions to other air discharge paths 13 around.

On the other hand, if one or both sides of the second shock absorbing layer 40 or regular irregular irregular portion 14 (mountain and valley) is formed, such as an egg plate structure, as shown in Figure 8, such a curved air discharge path 13 Can act as On the other hand, such a bend is better cushioning than the structure without the bend is also helpful for a natural swing.

9 illustrates a case in which the second shock absorbing layer 40 includes a granule structure or granule material. Granule structure is a structure having an excellent effect on the absorption of impact. The granule material of the present invention may be a material that most closely mimics the material or environment under the grass in the field such as sand or fine sawdust. In this case, it is preferable that the granule material is contained in the high elastic barrier film 15 so as not to be scattered even by the impact of the divot.

10 shows that the first shock absorbing layer 30 and the second shock absorbing layer 40 can be easily exchanged or rotated and reused by rotating the first shock absorbing layer 30 and the second shock absorbing layer 40. It illustrates the inclusion of supporting structures. As the user continues to use, the first shock absorbing layer 30 and the second shock absorbing layer 40 may not maintain their original shape, durability or elasticity. On the other hand, since the position where the divot is formed is not evenly distributed in all regions of the first shock absorbing layer 30 and the second shock absorbing layer 40, such reduction in durability or elasticity is caused by the first shock absorbing layer 30. And do not occur evenly in all regions of the second shock absorbing layer 40. Therefore, when the first shock absorbing layer 30 and the second shock absorbing layer 40 are rotated to be used, the service life of the first shock absorbing layer 30 and the second shock absorbing layer 40 may be substantially increased. It becomes possible. For the rotation, the first shock absorbing layer 30 and the second shock absorbing layer 40 may be rectangular but may be square. In order to increase the service life of the first shock absorbing layer 30 and the second shock absorbing layer 40, at least one of at least two of the first shock absorbing layer 30 and the second shock absorbing layer 40 is provided. It may be desirable to have the above divided structure. In the case of being divided, the first impact absorption layer 30 is formed by removing the artificial turf layer 50 and constituting the first impact absorption layer 30 or the second impact absorption layer 40.
