Description

Hole cup for golf putting practice {HOLECUP FOR GOLF TRAINIG}

The present invention relates to a hole cup for golf putting practice, and more specifically, to play on the actual putting green by accurately mastering the stroke and putting intensity (feeling of distance) control and direction that fit the distance from the hole cup when golfers practice putting indoors indoors. It is about a hole cup for golf putting practice that can effectively learn the same practical feeling.

In general, in order to play a golf game well, it is necessary to accurately determine the distance between the golf ball and the hole cup and the position and condition of the golf ball. In addition to impact action, golf ball hitting point and strength, as well as various kinds of approach shots (pitch shot, chip shot, lob shot, running shot), bunker shot, putting, etc. The delicate hitting method of the so-called short game of hitting must also be learned through repeated practice.

In particular, putting is the final stage of putting the golf ball into the hole cup. Based on a careful and stable posture, it is necessary to master the right direction, accurate distance measurement, consistent stroke without head-up motion, and mastery of distance through precise adjustment of putting intensity.

Recently, with the popularization of golf and the booming of the golf industry, a putting practice machine that can practice putting easily even in a relatively narrow place, such as indoors, is in the spotlight.

For example, in Patent Document 1, as shown in FIG. 1 , a hole 2 is formed by integrally forming an annular inclined wall 3 made of an elastic material on the upper surface of the circular base 1, and the inclined wall 3 An opening 3a is formed so that a golf ball enters the hole 2 by excising a portion of the hole 2, and in the center of the hole 2, a drop 5 is inclined by the coil spring 5a and the support member 5b. An acoustic hole cup for golf practice provided to protrude upward of the wall (3) is disclosed.

In Patent Document 2, as shown in FIG. 2, an inlet hole 7 is formed in the upper portion of the hole cup 1, and an echo tube 4 that emits a sound is provided inside the hole cup 1, and the ring tube ( 4) discloses a hole cup for putting practice provided with a sounding soundboard (5).

In such a conventional hole cup for putting practice, when a golf ball is hit in the direction of the hole cup with a putter, the golf ball passes over the inclined annular wall due to the rolling rotational force and enters the hole. The probability of hole-in is highest when the ring wall and the golf ball are square.

However, in the conventional hole cup for putting practice, due to the morphological characteristics of the inclined annular wall, the golf ball does not go into a hole as the direction changes along the inclined annular wall even if the golf ball only slightly deviates from the center of the annular wall. There are bound to be limits.

In other words, since the periphery and green of the actual hole cup on the green are flat, a hole can be made even if the golf ball slightly deviates from the center of the hole cup. There is a problem that I cannot.

Also, on the actual green, a hole cannot be made unless the golf ball rolls past the hole cup when putting, so it is most ideal to putt so that the golf ball passes exactly through the center of the hole cup and stops within the range of 30-50 cm (17 inches) for proper putting strength (feeling of distance). Because the conventional hole cup for putting practice is made of a material having elasticity such as rubber or silicone, and due to the physical and mechanical characteristics of the golf ball, it is necessary to apply more impact with the putting strength corresponding to the elastic force and repulsive force of the hole cup in order to make the golf ball hole in. There is a big difference from the actual green, and as a result, there is a problem that the utility and practicality are significantly lowered to accurately learn the actual feeling of the field.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to this, the terms to be described later are defined in consideration of the functions in the present invention, which indicate that they should be interpreted as concepts consistent with the technical idea of the present invention and meanings commonly or commonly recognized in the art.

In addition, if it is determined that a detailed description of a known function or configuration related to the present invention may obscure the gist of the present invention, the detailed description thereof will be omitted.

The accompanying drawings show that parts are exaggerated or simplified for convenience and clarity of explanation and understanding of the configuration and operation of the technology, and it is revealed that each component does not exactly match the actual size and shape.

In addition, in this specification, the term and/or is meant to include a combination of a plurality of related described items or any of a plurality of related described items, and when a part includes a certain component, it is a description that is specifically opposite Unless there is, it does not exclude other components, but means that other components may be further included.

That is, it means that there is a feature, number, step, operation, component, part, or a combination thereof described in this specification, and one or more other features or number, step operation component, part, or a combination thereof It is to be understood that this does not exclude the possibility of the existence or addition of those.

In addition, terms such as upper, lower, upper, lower, or upper, lower, upper, lower, etc. are used for convenience to distinguish relative positions of each component. For example, the upper part in the drawing may be named and referred to as the upper part and the lower part as the lower part.

3 to 5, the hole cup 10 for golf putting practice according to an embodiment of the present invention is made of an elastic material such as rubber or silicone and has the same size as the hole cup of the actual green, and the The main components include a base plate 11 , a hole-in space 12 , a friction protrusion 13 , and a seating protrusion 14 .

The base plate 11 is formed in a disk shape so as to be stably in close contact with the ground or the floor of a building, and has a predetermined width so that frictional force is generated on the contact surface when the golf ball is rolled.

In addition, the edge of the base plate 11 is formed in a shape having an inclined surface or a flexible curve that gradually decreases in thickness toward the edge of the base plate 11 so that the golf ball passes naturally without resistance when it rolls and collides according to the putting operation of the golfer. .

The hole-in space 12 is formed in the middle of the upper surface of the base plate 11 to allow a hole-in of a golf ball.

Here, the diameter constituting the region of the hole-in space 12 may be formed to be slightly smaller than the diameter of the golf ball (about 4.2 cm) so that the hole-in occurs only when the golf ball passes through the correct position.

In addition, the diameter constituting the area of the hole-in space 12 may be slightly larger than the diameter of the golf ball (about 4.2 cm) so that the golf ball enters naturally when it passes within a certain range.

For example, the diameter constituting the area of the hole-in space 12 is preferably formed to be 3 to 5 cm.

The friction protrusions 13 are closely arranged in a circle shape at regular intervals on the edge of the hole-in space 12 among the upper surfaces of the base plate 11 .

That is, the friction protrusion 13 is elastically deformed by elasticity with respect to the kinetic energy applied when the golf ball rolls in contact with the golfer according to the putting motion of the golfer and generates frictional resistance on the upper surface of the base plate 11 as if it were an actual putting green. Around the hole in the hall, several are formed densely and vertically at the same height, like a very short cut and manicured lawn.

These friction protrusions 13 provide a use environment that achieves conditions very similar to the hole cup on the actual putting green, and puts the golf ball in the direction close to the hole-in space 12 as in the actual putting green or with an appropriate putting strength. Even if an impact is applied, the golf ball is naturally induced and guided so that the golf ball enters the hole in the hole-in space 12 while flexibly deforming into a soft lying shape.

As a result, golfers can learn practical skills much more clearly and easily just like putting on the actual putting green.

Here, the friction protrusion 13 not only allows the golf ball to be elastically deformed more naturally and flexibly when the golf ball rolls in contact, but also stabilizes the elastic restoring force that quickly returns to its original shape when the golf ball is holed in or passed and interference such as external force is removed. It is preferable to form a truncated cone with a maximum thickness of 0.5 to 2 mm and a maximum height of 2 to 3 cm in the shape of a truncated cone whose diameter gradually decreases toward the top.

In addition, it is preferable that the outermost diameter formed by the area of the friction protrusions 13 is the same as or similar to the diameter of the hole drilled in the actual putting green of 108 mm.

The seating protrusions 14 are closely arranged at regular intervals on the bottom of the hole-in space 12 of the upper surface of the base plate 11 at a height lower than the height of the friction protrusions 13 .

That is, the seating protrusion 14 is elastically deformed by elasticity with respect to the kinetic energy applied upon contact according to the hole-in of the golf ball, and the adhesive force acts on the middle portion of the upper surface of the base plate 11 to prevent the progress of the golf ball. Several are formed densely and vertically at the same height.

Here, the seating protrusion 14 has a truncated cone shape that gradually decreases in diameter toward the top so that a more stable adhesive force acts when the golf ball contacts the hole-in space 12 while making a hole-in space 12, the maximum thickness is 0.5 to 2 mm, and the maximum height is 0.5 to 2 mm. It is preferable to form 0.2 to 0.5 cm.

The hole cup 10 for golf putting practice according to an embodiment of the present invention configured as described above applies an impact to the golf ball with an appropriate putting strength according to the distance from the putting position to the hole-in space 12 as in the actual putting green. A hole-in may be possible only when hitting in the direction close to (12).

That is, only when putting with the most ideal putting strength and impact and stroke, where the golf ball passes exactly through the center of the hole and stops in the range of about 30-50 cm (17 inch), the top surface of the base plate 11 appears as if it were a very short area around the hole on the actual putting green. Friction protrusions 13, which are densely erected vertically at the same height, like mowed and well-groomed grass, are elastically deformed by elasticity to generate frictional resistance sequentially and step by step so that the rolling golf ball does not deviate, and can be held stably.

Therefore, just like playing on the actual putting green, golfers can accurately and effectively master the precise putting stroke that matches the distance between the golf ball and the hole, as well as the ability to adjust the putting strength (sense of distance) and directionality accurately and effectively. can do.

On the other hand, the hole cup 10 for golf putting practice according to an embodiment of the present invention has excellent thermal stability and is made of unsaturated polyester resin, epoxy resin, phenol resin, silicone resin, polyurethane resin, etc. It can be integrally molded by injecting thermosetting plastic or synthetic resin into the mold.

On the other hand, the present invention is not limited by the above-described embodiment and the accompanying drawings, and can be variously modified and applied in various ways not illustrated within the scope without departing from the technical spirit of the present invention, as well as each It is clear to those of ordinary skill in the art to which the present invention pertains that it can be widely applied by changing the substitution of components and other equivalent embodiments.

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