Description

[0001] The present invention relates to a lightest point marking apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf ball lightest point marking apparatus, and more particularly, to a golf ball lightest point marking apparatus that can accurately and easily mark a lightest position in a golf ball.

As is known, a golf ball is composed of at least one inner layer selectively around the core, and a skin formed with dimples, which is shown in FIG.

The core of the golf ball is prepared by mixing and casting the chemical rubber with the mixture, placing the cast core into a mold, injecting the ionomer resin and mixture around the core to form an inner layer and a sheath, After that, they are completed by printing their mutual and direction directing lines.

In the golf ball thus manufactured, the center of gravity of the golf ball is formed at a position different from the center position of the core in the process of mixing the raw material of the core, casting process, ionizer resin, etc., The direction leader printed on the outer skin is unilaterally displayed by the manufacturer irrespective of the actual position of the golf ball at the lightest position or the heaviest heavier position, and therefore, the actual direction indicator is merely a meaningless display.

In order to solve such a problem, Korean Utility Model Publication No. 1990-0005055 (name of design: a hit point display device of a golf ball; hereinafter referred to as "cited invention 1") has been proposed as shown in FIGS. 2 and 3 2 and 3 as shown in Fig. 2 and Fig. 3 according to the first cited reference 1, the inner surface of the lid 2, in which the impact point marking hole 1 is opened, The motor housing case 6 is formed in close contact with the lower portion of the conical support portion 5 in which the shaft 3 and the flange 4 are formed at the upper end and the shaft hole 5 ' A small-sized motor is mounted so as to be closely contacted by the vibration-resistant portion of the elastic material, and a conical rotating plate 8 is inserted into the shaft hole of the support portion Axis through the motor shaft A case 10 having an operation switch on one side is fitted to a fitting projection of a flange lower end portion of the support portion and a lower case 12 having a battery housing chamber 11 is coupled to a lower end portion of the case. A vibration isolator 12a is attached to the upper end of the case so as to be closely contacted with the bottom surface of the motor housing case and a coupling portion 14'formed at the lower end outer fastener hole of the support portion is formed in a circular shape at the upper end of the lower case, Is formed to be fitted in the upper groove and is completely engaged as a fastening screw.

In the above-mentioned Reference 1, when the motor 9 is operated by pressing the operation switch 17 provided at one side of the case 10, the motor rotates the vibration vibration region 6a of the motor housing case 6 and the lower case 12 And the golf ball on the turntable rotates along the turntable, and at first, the deviation of the center of gravity and the geometric deviation of the center of the golf ball However, after about 20 seconds, the golf ball rotates while maintaining its center of gravity due to the weight and torque of the golf ball itself, so that a stable rotation axis is generated.

At this time, if the golf ball is confirmed to be rotating with its center of gravity maintained without vibration through the cover 3 of the lid, a suitable indicator such as a writing instrument or the like is put into the striking point indicating hole 1 of the lid, And a golf ball having a center point of the rotation axis is drawn out by opening the cover after the operation switch is cut off. The golf ball is displayed in the center of the rotation axis of the golf ball, The golfer flies in a direction selected by the golfer to fly, thereby causing a slicing phenomenon or a hooking phenomenon which is generated when the golfer hits the golf ball beyond the center of the golf ball unintentionally, The phenomenon can be significantly reduced, so that the golfer flies without leaving the direction of his or her choice at bat, When the center point of the rotation axis indicated on the golf ball is hit, the golfer rotates in the selected direction without excessive rotation due to the slipping or hooking phenomenon described above, and the buoyancy generated at this time is further strengthened, Since it was flying farther than when it hit, the golfer's ball could fly in the correct direction and increased distance.

On the other hand, Reference 1 has a complicated structure including a vibration suppressing structure and a high-speed rotating motor and a golf ball rotating and supporting structure which are expensive and capable of rotating the golf ball at a high speed, Rotation motor and golf ball rotation and supporting structure, it is rotated by the inertia force of the golf ball itself and is lifted while being lifted and the weight center line must be vertical. In fact, it is difficult to keep the center of gravity vertically as the golf ball floats, Even if the marking is performed for a short time during which the rotation center line is kept vertically while being floated, the marking pen is inserted through the hit point marking hole 1 for marking so that the golf ball comes into contact with the marking pen immediately, The golf ball rotation Geotyieoseo that is not in contact with the support structure as the vertical position of the weight center line can be maintained in a precise hitting point would appear difficult who had not been widely used.

In addition, since the time at which the center of gravity of the golf ball is instantaneously accelerated and rotated by the rotation of the golf ball is extremely short due to gravity and air resistance, there is a problem in that it is impossible to carry out the marking by capturing and marking the moment.

In the similar manner to the cited invention 1, the registered utility model No. 199671 (golf ball rotation center display device; hereinafter referred to as "cited invention 2") has been proposed, and all of them have a common structure, It is not.

Accordingly, in recent years, a golf ball is floated by using a brine having a specific gravity higher than that of a golf ball so that the top of the golf ball is exposed above the water surface. Then, the golf ball is drained so as not to shake, Korean Patent No. 1266061 (titled as a method of mass production of a real spin golf ball; hereinafter referred to as "cited invention 3") has been proposed.

According to the third cited reference 3, the golf ball 4 marked in the lightest position is mass-produced. However, the golf ball 4 is floated by using heavy salt water, So that the lightest position is exposed to the upper surface of the liquid surface, and then the golf ball 4 is drained at an extremely gentle speed so as not to shake the golf ball 4, There is a problem in that it is impossible to carry the equipment since it is necessary to use equipment consisting of a plurality of parts such as pumps P1 and P2 for supplying and draining water and control valves and storage tanks (not shown).

According to the third reference, there is no automatic process for displaying the putty line. Therefore, the marking still has to be dependent on a careful manual operation, resulting in low productivity.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The overall configuration of the golf ball 400 low center of gravity display device according to the present invention is shown in a perspective view of FIG. 5 and an exploded perspective view of FIG.

As can be seen from the above description, the present invention is characterized in that a floatation vessel 100 for floating a golf ball is provided, an injection hole 700 is provided above the floatation vessel 100, The intermediate portion is made of the flexible portion 101. The upper end of the floating tank 100 is provided with a coupling protrusion 102 or a coupling groove 201 to selectively couple or separate the upper cap 200.

The upper cap 200 according to the present invention is provided with a through hole 202 at the center thereof and a coupling protrusion 301 or a coupling groove 203 to be coupled to the cap 300 is formed around the through hole 202, Respectively.

In order to use the present invention as described above, the float tank 100 (hereinafter referred to as " solution ") having a specific gravity much higher than that of water is placed in the float tank 100, 400 is inserted into the flotation tank 100, the liquid level 600 should be set at an appropriate level such that the flotage rate is less than or equal to the upper end of the flotation tank 100.

In this state, the golf ball 400 is inserted through the input hole 700 above the floating tank 100.

As a result, the golf ball 400 floats inside the floating tank 100 and is allowed to freely rotate. At this time, the lightest point WL of the golf ball 400 is positioned at the upper end, And the center of gravity axis becomes a vertical phase.

Accordingly, the upper end of the golf ball 400 is exposed on the liquid level 600 of the solution, and then the upper cap 200 is coupled to the upper end of the floating tank 100, and this state is shown in FIG.

In this state, the golf ball 400 rotates so that the heavy weight moves downward and the lightest weight moves to the upper end. In this state, the cap 300 above the upper cap 200 The marking pen is inserted into the through hole 202 at the center of the upper cap 200 as shown in FIG.

However, in this process, when the lower end of the marking pen touches the golf ball 400, the ball 400 rotates freely on the solution because it is in a highly fluid state and can not be properly marked.

Therefore, according to the present invention, the weight of the golf ball 400 floating on the solution surface 600 of the golf ball 400 is made to be the lightest position, When the flexible part 101 is held and held by two fingers in a state in which the solution water is minimized in the upper center of the golf ball 400 by causing the liquid on the upper part to flow downward, The upper end of the golf ball 400 is brought into close contact with the upper end of the upper cap 200 and does not move. In this state, the marking pen is moved to the center of the upper cap 200 And is displayed in the through hole 202.

In this state, however, since the golf ball 400 is in contact with the inner circumferential surface of the upper cap 200 and is in a non-moving state, accurate marking can be performed with the marking pen prepared in advance. .

The lower end of the marking pen prepared in advance in the state in which the periphery of the lightest point WL of the golf ball 400 having the smallest weight is in close contact with the inner upper end of the upper cap 200 is inserted into the through hole 202 of the upper cap 200 And marking by the marking pen is completed on the lightest point WL of the lightest weight of the golf ball 400. [

In addition, it is preferable that the marking pen used in the present invention has high volatility so as to be dried at the same time as the marking, and it is preferable to use a lubricant pen so that the marking is not discolored or dispersed by the solution.

After the completion of the marking, the two flexible fingers 101 are released to allow the flexible portion 101 to return to its original shape. The golf ball is lowered to the standby position, The upper cap 200 is separated from the floating tank 100 by separating the coupling protrusion 102 of the floating tank 100 and the coupling groove 201 from each other so that the golf ball 400) and use it.

The golf ball 400 thus taken out is wiped with water and washed with water to remove the solution, thereby marking the golf ball 400 in the lightest weight position is completed, and the position of the lightest point WL is reversed And the center of gravity is formed between them.

Then, the unmarked golf ball 400 is inserted into the insertion hole 700 of the floating tank 100 as described above, and the golf ball 400 is marked by the same process.

After the marking of the golf ball 400 is completed, the upper cap 200 is coupled to the upper portion of the floating tank 100 using the coupling protrusion 102 and the coupling groove 201, 5, the solution can be repeatedly used by preventing the solution from leaking out by being fitted in the upper part of the upper cap 200 to close the upper cap 200. The solution can be conveniently carried at any position.

In the golf ball 400 according to the present invention having the markings thus completed, the impact of the driver is applied to the heaviest point WH having the largest weight as shown in FIG. 9 in the case of a T shot using a driver or a wood or iron And the lightest point WL is directed toward the target point, the golf ball 400 receives the impact in a state in which the center-of-gravity line is aligned toward the target direction, so that the golf ball 400 is deformed at the time of impact, The eccentric force that causes the rotation of the golf ball 400 itself after the flight due to the impact by the driver is minimized while performing the flight in the target direction, so that the ball does not fly in the leftward direction or the rightward direction due to the excessive rotation So that the occurrence of hooks and slices can be minimized.

This is because when the weight of the golf ball is located at the side rather than the impact position with respect to the driver, the impact due to the driver causes an eccentric force due to the mismatch between the center of gravity of the golf ball 400 and the impact direction, Or in the right direction to prevent it from dropping to an unintended position.

In addition, in the golf ball 400 according to the present invention, as shown in FIG. 10, the most weighted point (WH) is downward and the lightest point (WL) The impact by the putter is applied in the hole direction. In this case, the golf ball 400 marked according to the present invention receives the impact, and the most weight point WH and the lightest weight point WL, which are heavy in weight, form a straight line with the hole direction, It rotates in the center and rolls in the hole direction, so that it is more likely to enter the hole by being exactly rolled in the hole direction.

This is because the golf ball 400 is impacted in the center of the golf ball 400 in a state in which the most weight point WH having a heavy weight and the lightest point WL having a small weight are not aligned with the hole direction, It is possible to reduce the number of putts by restraining the player from rolling in a direction other than the intended direction, thereby improving the performance.

In the present invention, it is preferable that the flexible portion 101 is made of a transparent material.

In other words, in the present invention, when the flexible portion 101 is made of a transparent material, it is possible to confirm the lifting of the golf ball 400 and visually confirm that the golf ball 400 is lifted by pressing it with fingers, .

When the flexible portion 101 pushes up the golf ball 400 by forming a fine protrusion 500 having a size much smaller than the dimple of the golf ball on the inner circumferential surface of the flexible portion 101, So that it can be brought into close contact without causing slippage by friction on both sides, so that it is possible to mark at an accurate position.

In addition, it is not desirable that the golf ball 400 touches the inner surface of the upper cap 200. Therefore, the fine protrusions 500, which are much smaller than the dimples, Is not moved by the frictional force with the fine protrusions 500, so that marking can be performed at an accurate position.

 Although the cap 300 is attached to and detached from the upper cap 200 by the coupling protrusion 203 and the coupling groove 301 in the present invention, Any structure that can be applied is applicable.

In the present invention, the upper cap 200 is detached from the upper end of the floating tank 100 by the coupling protrusions 102 and the coupling recesses 201. The coupling protrusions 102 and the coupling recesses 201 ) May be of any type as long as it is possible to prevent leakage of the solution and to stably mark the solution.

In addition, as described in the above embodiment of the present invention, the golf ball 400 is lifted using only a minimized amount of the solution to float the golf ball 400, and the golf ball 400 is moved to the flexible portion 101 The solution is not buried in the hand during the marking process by pushing up and marking, and the volume can be minimized, so that it can be manufactured in a size optimized for carrying.

Although the description of the apparatus according to the present invention for marking the lightest point WL of the golf ball 400 has been described above with reference to the accompanying drawings, it is to be understood that the present invention has been described by way of example only, But is not limited to.

Accordingly, it is a matter of course that various modifications and variations of the present invention are possible without departing from the scope of the present invention. And are included in the technical scope of the present invention.
