Description

Rope for golf swing training {ROPE FOR GOLF SWING TRAINING}

The present invention relates to a rope for golf swing practice that allows the golfer to swing the ball as if he is actually swinging without a ball, while correcting the posture and developing the force to increase the flying distance of the ball, and more particularly, to a golfer's accurate swing practice and correct swing It relates to a fiber rope for learning posture.

Golf is an exercise that strikes a ball using rotational torque obtained by the inertia and centrifugal force of the club head, and it is necessary to learn the motion of swinging a golf club according to a certain trajectory so that the ball flies to the desired pitch and the distance is improved.

As an apparatus for practicing such a golf swing motion, for example, Patent Document 1 discloses a golf swing practice mechanism. That is, as shown in Fig. 1, the flexible rope 32 is connected to the lower end of the grip 30, and the spherical body 33 is fixed to the end of the flexible rope 32, but this 32)'s resilience is insufficient, so the practice time is lengthened, and there is a limit that golfers cannot feel the speed properly when swinging.

Recently, a rope for golf swing practice has been proposed in which both ends of a fiber rope are tied together and a belt is wound to create a grip part, and a ball is attached to the center part.

However, this is because the fiber rope is made of synthetic fibers such as nylon, polyester, vinylon, etc., and the touch is not soft, and elasticity and flexibility are significantly reduced.Therefore, when practicing the swing movement, there is a risk of hitting the golfer's skin and causing abrasion.

In addition, due to the elasticity, the shape stability is deteriorated and it is easily stretched, so the coordination motion and impact timing of each joint of the body mobilized during the swing motion are not well made, so there is a problem that the exercise effect is insignificant such as the ball part fits the body of the golfer.

The background technology or the prior art described herein is information possessed by the present inventor or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention, and the technology to which the present invention belongs prior to the filing of the present invention. It should be noted that it does not mean a technique widely known in the field, and in addition, reference numerals in the prior art are mutually independent of reference numerals in the present invention.

As shown in FIGS. 2 and 3, the rope for golf swing practice according to an embodiment of the present invention largely includes a core part 10, a support part 13, and a covering part 15.

The core part 10 is to maintain stiffness against deformation and to ensure durability against external force, and is surrounded by a support part 13 and a covering part 15 so that it can be protected from external impact. have.

That is, the core portion 10 is a twisting (twisting) combination of several strands 11 made by twisting and joining tens of strands of a wire made of textile fibers or high tensile fiber yarns in a Warrington type or lang lay. It consists of a form.

For example, the core portion 10 is formed in a form of twisting 8 strands of strands 11 having a diameter of 2 mm to 4 mm, and thus can stably support even if an external force of a considerable load acts.

Here, as shown in FIG. 3, the core part 10 is a combination of several strands 11 made by twisting dozens of strands made of textile fibers or high-tensile fiber yarns together around the core 12 made of nylon monofilament, as shown in FIG. It can be made in a form.

That is, the nylon core 12 of a circular cross section with high resistance to repetition and bending and excellent recovery power is embedded in the center of the core part 10 as a single strand, so that it is elastically deformed during the swing operation, and the overall shock absorption and tension of the rope. As a result, it is possible to naturally and effectively match the coordination motion, impact zone, and timing of each joint of the body mobilized during the swing motion, thereby enabling accurate swing in a stable posture.

The support part 13 is for maximizing elasticity and flexibility, and obtaining a feeling of weight and volume that does not become soft, and a first artificial leather string 14 of several strands is woven along the outer circumference of the core part 10. It is woven so as to intersect in a Stitch) shape and wraps the core part 10 as if covering.

That is, the support portion 13 surrounds the outside of the core portion 10 by woven several strands of the first artificial leather string 14 into a hollow tube shape.

In addition, the first artificial leather strap 14 is formed of a polyurethane material and a shape in which both edges of the strip-shaped strap are folded flat and attached so as to contact each other.

For example, the support portion 13 is a woven stitch (1st artificial leather string 14) 6 strands folded flat so as to overlap each other in the width direction of the polyurethane string with a thickness of 0.8 mm to 1.5 mm. Woven Stitch) can be formed by weaving it to intersect.

On the other hand, the first artificial leather strap 14 is attached with an adhesive such as natural latex in a state where both edges of the strip-shaped strap are folded as shown in FIG. 4 to provide a certain size of volume. The size may be 1/5 to 1/2 of the size of the entire width. For example, it is preferable that both ends of the strip-shaped string are almost abutted so that there is no unfolded space.

Here, if the folded width of the first artificial leather strap 14 is less than 1/5 of the total width, the size of the space remaining without being folded during bonding is too large, so the adhesive strength as well as the volume and buffering power may be lowered. If it is large, it is not preferable because it may overlap with the folded portion on the opposite side.

In addition, the first artificial leather strap 14 applies heat and pressure at the same time by passing it between two rollers rotating in engagement with each other in order to improve adhesion and fix it in a certain shape in a state where both edges are folded inward. The orientation and size may vary. For example, if pressure is applied to the folded part only in the vertical direction, a rather elongated cross-sectional shape can be obtained, and if pressure is applied in both the vertical and horizontal directions, a rather large cross-sectional shape with a relatively large volume and cushioning feeling can be obtained. You can get it.

The covering part 15 protects the core part 10 and the support part 13 while maximizing elasticity and flexibility, and to obtain a smooth and soft touch, and several strands along the outer circumference of the support part 13 The 2nd artificial leather string (16) is woven so as to intersect in the shape of a woven stitch and is wrapped around it as if covering.

That is, the covering portion 15 surrounds the outside of the covering portion 15 by weaving several strands of the second artificial leather string 16 in the form of a hollow tube.

In addition, the second artificial leather strap 16 has a shape in which both edges of the strap made of polyurethane are folded flat and attached to each other.

For example, the covering portion 15 is a woven stitch (8 strands of the second artificial leather strap 16) folded flat so that they overlap each other in the width direction of the polyurethane strap with a thickness of 0.1 mm to 0.3 mm. Woven Stitch) can be formed by weaving it to intersect.

In addition, the second artificial leather strap 16 is a material having a thinner thickness and a soft surface than the first artificial leather strap 14 in order for the covering portion 15 to adhere to the outer circumference of the support portion 13 thinly and closely. It is formed with.

That is, the second artificial leather strap 16 is made of a polyurethane strap that is thin, soft and elastic, and improves the bonding property with the outer circumference of the support part 13 to prevent slipping away from each other. And, it is possible to reduce frictional heat due to mutual friction, and increase abrasion resistance against frequent external forces such as external torsion or stress.

Here, the second artificial leather strap 16 is attached with an adhesive such as natural latex in a state where both edges of the strip-shaped strap are folded as shown in FIG. 5 to provide a certain volume of volume, and the size of the folded width of one side May be 1/5 to 1/2 of the size of the entire width. For example, it is preferable that both ends of the strip-shaped string are almost abutted so that there is no unfolded space.

In addition, if the folded width of the second artificial leather strap 16 is less than 1/5 of the total width, the size of the space remaining without being folded during bonding may be too large, and if it is greater than 1/2, the folded side may be folded on the opposite side. This is not desirable because it may overlap with parts.

In addition, the second artificial leather strap 16 applies heat and pressure at the same time by passing it between two rollers rotating in engagement with each other to improve adhesion and fix it in a certain shape with both edges folded inward. The orientation and size may vary. For example, if pressure is applied to the folded part only in the vertical direction, a rather elongated cross-sectional shape can be obtained, and if pressure is applied in both the vertical and horizontal directions, a rather large cross-sectional shape with a relatively large volume and cushioning feeling can be obtained. You can get it.

On the other hand, the first and second artificial leather cords 14 and 16 are formed by needle punching a web made by opening, carding, and cross-wrapping single fibers of sea-island type composite fibers. After immersing and impregnating the dimensionally intertwined nonwoven fabric in the impregnating polyurethane solution, take it out and press it with a mangle (Mangle/Press Roll) to squeeze it, and then knife coat the polyurethane solution for application on the surface of the nonwoven fabric. Apply using method, comma coating method, bar coating method, roll coating method, etc., coagulate polyurethane in a coagulation bath, wash with water, dry, and treat with an aqueous alkali solution to remove the eluted component from the composite fiber, resulting in a single yarn fineness of 0.3. It can be made of fine-sized to less than denier, heat-treated, and buffed with abrasive paper to form napped hair on the surface and dyed.

Here, the sea-island composite fiber is made of polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, or polyamide as the island component, and the sea component is polystyrene, polyethylene, modified polyester, which have different alkali solubility from the island component. Polyester or the like can be used.

And the polyurethane solution for impregnation may be obtained by dissolving polyurethane in an organic solvent such as dimethylformamide (DMF), which has a solid content of 10 to 14% by weight compared to the total 100% by weight, and the viscosity of the solution is 1000±200 cps ( 25°C) is preferable from the viewpoint of processability.

In addition, when the polyurethane solution is impregnated by immersing the nonwoven fabric, the initial impregnation amount in a wet state may be 130 to 170 parts by weight relative to 100 parts by weight of the nonwoven fabric, and 80 to 120 parts by weight through compression.

In addition, it is preferable to control the impregnation amount by performing pressure on the nonwoven fabric by pressing and squeezing it under conditions of 1 to 3 kgf/cm 2, and the gap between mangles is 70 to 80% compared to the thickness of the nonwoven fabric.

In addition, the wet coating amount may be 50 to 80 parts by weight based on 100 parts by weight of the nonwoven fabric in terms of texture, and the coating amount after drying is preferably 10 to 20 parts by weight based on 100 parts by weight of the nonwoven fabric.

In addition, the polyurethane solution for application may be obtained by dissolving polyurethane in an organic solvent such as dimethylformamide (DMF), which has a solid content of 16-20% by weight and a viscosity of 2000±200 cps (25℃). It is preferable in terms of coatability.

In addition, a single yarn fineness of 0.3 denier or less after the micro-fine treatment is good for improving flexibility and surface appearance, and the micro-fibers are three-dimensionally entangled with each other to prevent a decrease in strength.

In particular, the second artificial leather string 16 may use a polyurethane prepared from an ether-based polyol as a polyurethane solution for impregnation, and a polyurethane prepared from a polycarbonate-based copolymerized polyol as a polyurethane solution for coating.

That is, the polyol component of the polyurethane prepared from the ether-based polyol is preferably an ether-based polyol such as polypropylene glycol (PPG), polytetramethylene ether glycol (PTMEG), and polyethylene glycol (PEG). The polyurethane can give the elasticity and flexibility of the second artificial leather strap 16 and exhibit a texture similar to that of natural leather. More preferably, using a polyurethane prepared from polytetramethylene ether glycol can improve hydrolysis resistance and low temperature characteristics.

In addition, if the second artificial leather string 16 is impregnated with only polyurethane made from ether-based polyol, the texture is remarkably improved, but because of the lack of mechanical properties, the non-woven fabric is used to improve abrasion resistance, heat resistance, including elasticity, while maintaining improved texture. After immersion and compression treatment, the polyol portion is made from a polycarbonate-based copolymer polyol consisting of a copolymer of 1,4-BD and 1,5-PD or a copolymer of 1,5-PD and 1,6-HD. Urethane can be coated on the surface.

In addition, the first and second artificial leather straps 14 and 16 may be made of solvent-based polyurethane synthetic leather, water-based polyurethane synthetic leather, or the like.

As described above, the rope for golf swing practice according to an embodiment of the present invention has a triple-stranded structure to enhance tensile strength and durability against repeated bending and torsion, as well as excellent elasticity and resilience, and can stably maintain flexibility for golf swing practice. It bends naturally and elastically like the shaft of an actual golf club, and can be quickly restored to its original state.

Therefore, the exercise effect of increasing the distance of the ball by improving the swing posture and maintaining the swing trajectory horizontally by minimizing the distortion and loss of balance during the golf swing and impact can be greatly improved.

In addition, the support part 13 and the covering part 15 are formed by covering layer by layer with an artificial leather strap, that is, the first and second artificial leather straps 14 and 16 each have a width on both edges of the strap made of polyurethane. Because it is formed in two layers by folding it flat in the direction, it is possible to increase shape stability and resilience, and this allows you to swing naturally and smoothly, find the impact point with a sense of rhythm and accuracy, as well as give the backswing a heavy feeling without blurring. In the process, it can be naturally swung up to the finish without fluttering.

In addition, by implementing a cushioning effect with a smooth and soft touch, it can improve emotional quality and prevent abrasions on the skin during practice.

On the other hand, the present invention is not limited by the above-described embodiments and the accompanying drawings, and can be variously modified and applied in various ways that are not illustrated within the scope not departing from the technical spirit of the present invention. It is obvious to those of ordinary skill in the art that substitutions and other equivalent examples may be applied widely.

Therefore, the contents related to modification and application of the technical features of the present invention should be interpreted as being included within the spirit and scope of the present invention.
