Description

Technical Field

[0001] The present invention relates to a natural turf mat device for golf practice. More specifically, it is installed in a screen golf course and an indoor golf practice range, and provides a golf practice mat planted with natural turf, enabling practice of swinging and hitting under the same or similar conditions as an actual field. The present invention relates to a natural turf mat device for golf practice.

Background Art

[0002] Generally, in order to accommodate a large number of people in a limited space, golf practice ranges have artificial mats laid in a certain space with a uniform size and arranged at uniform intervals. Such golf practice mats use artificial mats processed into products made of plastic or synthetic resin. In artificial mats, there are drawbacks such as the inability to acquire the hitting feeling of a swing that can actually be felt when a golf club receives the resistance of natural turf, and the inability to master the accurate square and impact when hitting a golf ball.

[0003] That is, an artificial mat cannot hold a golf ball in an accurate square and hit it. Even if a duff (a mistake of hitting the ground behind the ball) occurs, the golf club is pushed by the smooth artificial mat and hits the golf ball, so there is a problem that golfers cannot acquire an accurate square and a correct swinging feeling.

[0004] This is the difference between hitting a ball on natural turf and hitting a ball on an artificial mat. Another decisive difference is the difference in weight feeling. In the mat, only the ball is hit, but on natural turf, the turf is also hit together.

[0005] Therefore, there is a risk that a practitioner who has mainly been practicing on a mat may feel a sense of disconnection when going out to the field and hitting the ball. The user may suddenly stop their swing due to the different weight feeling compared to the practice range where the club touches the ground, and a situation may occur where the swing that was smooth and stable enough to finish smoothly with the golf club in the practice range is interrupted in the field.

[0006] As a result, a method is desired to provide natural turf as a golf practice mat to eliminate the above-mentioned drawbacks of artificial mats and enable the user to acquire the sense of balance for accurate hitting of the golf ball and a correct swing.

[0028] The features of the various embodiments of the present invention can be partially or wholly combined or combined with each other, and various linkages and drives are technically possible as can be fully understood by those skilled in the art. If each embodiment can be independently implemented with respect to each other, it is also possible to be implemented together with a correlative relationship.

[0029] Hereinafter, various embodiments of the present invention will be described in detail based on the accompanying drawings.

[0030] FIG. 1 is a perspective view showing a natural turf mat device for golf practice according to an embodiment of the present invention. FIG. 2 is a perspective view showing the natural turf mat device for golf practice of FIG. 1 in an extended state. FIG. 3 is a diagram for explaining the support and conveyor drive structure of the natural turf mat device for golf practice of FIG. 1.

[0031] Referring to FIGS. 1 to 3, a natural turf mat device for golf practice (hereinafter referred to as the natural turf mat device) according to an embodiment of the present invention includes a housing 110, a conveyor belt 120, drive units 130a and 130b, a natural turf mat 140, fixed support parts 150a to 150d, connecting parts 160a and 160b, and rollers 170, and may further include a first operation part 10 for controlling the drive and drive direction of the drive units 130a and 130b and a second operation part 20 for controlling the expansion and contraction of the fixed support parts 150a to 150d.

[0032] The housing 110 includes a housing top surface 110a having an opening 110h and a housing placement box 110b. The device main body is installed in the housing placement box 110b, and a partial area of the natural turf mat 140 is exposed in the opening 110h of the housing top surface 110a so that a user can use it as a mat for golf practice.

[0033] FIG. 4 is a diagram showing a golf practice range in which the natural turf mat device for golf practice according to an embodiment of the present invention is installed. Referring to FIG. 4, the natural turf mat device for golf practice according to an embodiment of the present invention may be installed and used in a screen golf course and an indoor golf practice range, or the housing 110 may be recessed and placed in a partial area of the floor surface 1 where the user stands, and the housing top surface 110a may be provided horizontally with the floor surface 1.

[0034] At this time, for example, the housing top surface 110a may be manufactured to have a length (horizontal) of 1000 mm and a width of 350 mm, and the housing placement box 110b may be manufactured to have a height of 200 mm, a length (horizontal) of (1000 + α) mm, and a width of (350 + α) mm. Note that the size can be adjusted according to the installation environment.

[0035] The conveyor belt 120 may be provided inside the housing placement box 110b, and a natural turf mat 140 may be fixedly coupled to the outer peripheral surface. The conveyor belt 120 can be driven by drive units 130a and 130b, and the drive units are provided at both ends of the conveyor belt 120 to rotate and move the conveyor belt 120 along the longitudinal direction, and can move in one direction or the other direction.

[0036] Therefore, the natural turf mat device according to an embodiment of the present invention can be installed in the structure of the housing 110 recessed below the floor surface 1 in a limited indoor space to utilize the space. In particular, using the conveyor belt structure placed on the housing placement box 110b, the natural turf mat 140 is continuously planted not only on the housing top surface 110a for the batting area but also on the lower part (the outer peripheral surface of the lower part of the conveyor belt 120) facing the housing top surface 110a along the outer peripheral surface of the conveyor belt 120, and a wide batting area can be secured in the limited indoor space.

[0037] A plurality of mat fixing portions 125 may be formed on both side surfaces of the conveyor belt 120 perpendicular to the longitudinal direction at a predetermined interval. The plurality of mat fixing portions 125 are provided at a predetermined interval from each other along the longitudinal direction of the conveyor belt 120. The plurality of mat fixing portions 125 may extend perpendicularly in the direction outside the conveyor belt 120 by a certain length from both sides in the direction perpendicular to the longitudinal direction (width direction) of the conveyor belt 120, and then be bent and extended in a direction parallel to the conveyor belt 120. The mat fixing portion 125 may include a portion extending in the thickness direction of the conveyor belt 120 and a portion extending inward in the width direction of the conveyor belt 120 from the end of that portion. A natural turf mat 140 may be fitted and fixed to the plurality of fixing portions 125. Generally, in a golf driving range or a screen golf course, due to the characteristics of the facility structure, one has to move at a limited position and uses a fixed mat, so the place to place the ball has to be concentrated on a specific part (the middle), resulting in many partial depressions. As a result, the sense of presence and realism are inferior. In contrast, in the present invention, the natural turf mat 140 can be used while being moved using the conveyor belt 120, and after using the natural turf mat 140, it can be replaced with a new natural turf mat 140 and used, and one can exercise under the best conditions every time.

[0038] Referring to FIGS. 5 and 6, the coupling structure between the natural turf mat 140 and the mat fixing portion 125 for fixing the natural turf mat 140 can be confirmed. FIG. 5 is an enlarged view of the a region in FIG. 1. FIG. 6 is a cross-sectional view for explaining the coupling structure between the natural turf mat 140 and the mat fixing portion 125.

[0039] FIG. 5 is an enlarged view of the a region in FIG. 1, and FIG. 6 is a coupling structure between the natural turf mat 140 and the mat fixing portion 125 that can be confirmed by viewing the natural turf mat device in FIG. 2 in a cross-sectional view taken along the A-A' arrow. The natural turf mat 140 has a shape that abuts on and surrounds the outer peripheral surface of the conveyor belt 120, and is configured to be fixed by the mat fixing portions 125 provided at a predetermined interval on the conveyor belt 120.

[0040] Referring to FIG. 6, after extending the length in a direction perpendicular to the conveyor belt 120 from both sides in the width direction of the conveyor belt 120, a mat fixing portion 125 having a structure that is parallel to the conveyor belt but bent in the direction of the conveyor belt to extend the length can be confirmed. Natural turf mats 140 may be fitted and fixed to the mat fixing portions 125 on both sides of the conveyor belt 120, and a part of the area of the fitted and fixed natural turf mat 140 is exposed through the housing top surface 110a, and the exposed natural turf mat 140 can be used as a mat for golf practice.

[0041] At this time, the natural turf mat 140 may include a vegetation mattress 141 and a turf layer 142 planted on the vegetation mattress 141.

[0042] The vegetation mattress 141 can form a mattress net from natural fibers such as coconut fiber (COCO Coir), jute felt, or rock wool. The inside of the mattress net may contain a mixture of natural materials such as natural rubber and latex, and nutrients for turf vegetation. A turf layer 142 planted on the vegetation mattress 141 may be formed on the upper part of the vegetation mattress 141. For this reason, the vegetation mattress 141 allows the turf to grow continuously, absorbs impacts such as those from an iron by the elasticity of the mat to protect the body of the user 2, and can ensure elasticity by belt-type driving. Therefore, practice can be carried out under conditions that are maximally the same as those of the actual field without a sense of deviation from the actual field turf.

[0043] The natural turf mat 140 of the present invention has the same resistance value at the time of impact between the ball and the club in an actual field, and is different from an artificial mat for practice that can hit the ball even without an accurate impact, and has a high practice effect.

[0044] In general, when using a practice mat, the impact is directly transmitted to the wrists, arms, and shoulders. However, since the natural turf mat 140 of the present invention uses natural turf and mat materials with low hardness (COCO Coir, Jute Felt, Rock Wool), it has excellent shock absorbency and can prevent injuries. At this time, the natural turf mat 140 can be trimmed by adjusting the length of the turf immediately before use. Generally, in a golf driving range or a screen driving range, since mats of the same standard are used, practice can be carried out only on the premise of the fairway situation. However, the natural turf mat of the present invention can be trimmed by adjusting the length of the turf, that is, the vegetation matress 141, immediately before use. Therefore, customized practice can be carried out according to various environments such as fairways and roughs.

[0045] Furthermore, the connecting portions 160a and 160b can connect a pair of fixed support portions that face each other and support different driving portions among the plurality of fixed support portions. More specifically, referring to FIG. 2, the fixed support portion may include a first fixed support portion 150a and a third fixed support portion 150c that fixedly support both sides of the first driving portion 130a, and a second fixed support portion 150b and a fourth fixed support portion 150d that fixedly support both sides of the second driving portion 130b.

[0046] At this time, the first fixed support portion 150a and the second fixed support portion 150b are connected to the first connecting portion 160a, and the third fixed support portion 150c and the fourth fixed support portion 150d are connected to the second connecting portion 160b, so that the driving portions 130a and 130b can be stably and firmly fixedly supported. Therefore, irons and utilities can be used.

[0047] In addition, the first connecting portion 160a and the second connecting portion 160b are spaced apart from the conveyor belt 120 by a certain distance and do not affect the driving of the conveyor.

[0048] Furthermore, a plurality of rollers 170 are formed at the upper ends of the first connecting portion 160a and the second connecting portion 160b at a predetermined interval, and the plurality of rollers 170 are coupled between the first connecting portion 160a and the second connecting portion 160b, but can be rotatable by bearings or the like.

[0049] The plurality of rollers 170 support a part of the conveyor belt 120 (the conveyor belt 120 located on the top surface 110a of the housing), and can guide and guide the movement of the conveyor belt 120 when the driving units 130a and 130b are driven.

[0050] FIG. 7 is a diagram for explaining the operation units 10 and 20 according to an embodiment of the present invention. The natural turf mat device according to an embodiment of the present invention further includes a first operation unit 10 and a second operation unit 20, and the driving units 130a and 130b are driven and controlled according to a user control command using the first operation unit 10, and the telescopic movement of the fixed support portions 150a to 150b can be controlled according to a user control command of the second operation unit 20.

[0051] More specifically, the first operation unit 10 can be a wired or wireless type remote control, and a control command for rotating the driving units 130a and 130b in one direction or the other direction can be input so that a part of the natural turf mat exposed at the opening 110a is adjusted.

[0052] Through this, the user can adjust and use the position of the natural turf mat 140 according to the state of the lawn at the position where the batting preparation has already been completed so as to match the hitting position. In addition, the elasticity of the lawn can be ensured by belt-type driving. Furthermore, the natural turf mat device of the present invention can provide a large number of usage times by conveying and using the natural turf mat 140 by a conveyor.

[0053] Further, the second operation unit 20 can be a wired or wireless remote control, and can receive an input of a second control command for extending or retracting the fixed support parts 150a to 150d. According to the second control command, the fixed support parts 150a to 150d can be extended or retracted.

[0054] The fixed support parts 150a to 150d may be formed in a multi-stage structure, and can be extended or retracted in multiple stages according to the second control command by using a hydraulic cylinder or gear drive, etc. When the user needs to replace the natural grass mat 140 due to multiple uses, first, after removing the housing top surface 110a, extend the fixed support parts 150a to 150d to lift the main body placed and installed in the housing placement box 110b, that is, the conveyor belt 120, the drive parts 130a, 130b, the natural grass mat 140, the connecting parts 160a, 160b, and the roller 170 as a whole. After lifting the main body and removing the natural grass mat 140, it can be replaced with a new natural grass mat and fitted. Note that the conveyor belt 120, the drive parts 130a, 130b, the natural grass mat 140, the connecting parts 160a, 160b, and the roller 170 may be lifted in a state where the housing top surface 110a is not removed. The conveyor belt 120, the drive parts 130a, 130b, the natural grass mat 140, the connecting parts 160a, 160b, and the roller 170 may be lifted above the housing top surface 110a.

[0055] Next, after reducing the fixed support parts 150a to 150d and placing them in the housing placement box 110b again, the housing top surface 110a can be joined again. For example, the housing top surface 110a can be joined to the housing placement box 110b by fitting or the like.

[0056] The above has further described an embodiment of the present invention in more detail based on the attached drawings. However, the present invention is not necessarily limited to such an embodiment, and various modifications can be made and implemented within the scope without departing from the technical idea of the present invention. Therefore, the embodiments disclosed in the present invention are not for limiting the technical idea of the present invention, but for explanatory purposes, and the scope of the technical idea of the present invention is not limited by such embodiments.
