PORTABLE CASE FOR GOLF ACCESSORIES

TECHNICAL FIELD

The present invention relates to a portable case for golf accessories. More specifically, the present invention relates to a case for accessories, which enables persons enjoying golf to easily and comfortably carry golf accessories required in a field when the persons go out into the field. In other words, the present invention relates to a portable case for golf accessories, in which a user may carry various golf accessories such as various tees, markers, and green repair devices as well as golf balls by inserting the golf accessories into one case and wearing the case at a waist, may take out and use each of the golf accessories whenever necessary, and may easily insert the golf accessories again after use. According to the case for the golf accessories of the present invention, the user may freely perform a golf swing while carrying various golf accessories by easily and comfortably fitting and storing the golf accessories in the case. In particular, a golf ball may be easily fitted to the case and comfortably separated from the case with less force upon the separation, whereas once the golf ball is fitted to the case, the golf ball may be carried while being stably fitted without being easily separated even when the golf ball is caught on a tree branch, a hem, or the like. In addition, a case for golf accessories, which is not obstructive upon exercise or walking, may be provided since a size of the case is minimized through an optimized structural design.

BACKGROUND ART

In general, golfers who enjoy golf carry various accessories in addition to golf clubs and golf balls. For example, the golfers play a game while carrying basic items required for the game, such as various tees for tee shots, markers for marking a position in which a ball of the golfer was located on a green, and green repair devices for repairing a green damaged by a swing. In particular, since a large number of natural environments such as forests and ponds, structures, and the like exist within a golf course, the golf balls may be frequently lost during a golf game, so that the golfers necessarily carry spare golf balls to ensure smooth game play.

However, most golfers carry the golf accessories including the golf balls in pockets, in which the items may be obstructive upon walking or exercise when the items are carried in the pockets, and the game may be frequently delayed due to a time required for finding the item when the golfer alternately searches through one pocket and another pocket while trying to find the item in a hurry. In addition, the items were frequently lost while searching through the pockets.

To solve the above problems, various portable cases for golf accessories, capable of systematically storing and carrying various golf accessories have been developed. For example, Korean Patent Registration No. 10-0756733 (Sep. 7, 2007), Korean Utility Model Registration No. 20-0384076 (May 11, 2005), Korean Patent Registration No. 10-1303927 (Sep. 5, 2013), and the like disclose portable cases for golf accessories, in which various golf accessories such as tees or markers as well as golf balls are put in one storage case, and the storage case is worn at a waist.

However, according to the related art described above, a lid or a cover has to be opened when a golf ball is being taken out, which causes inconvenience in use, or there is a risk of loss of a golf ball because the golf ball may be easily separated when the golf ball put in the case for the golf accessories is caught on a tree branch or the like, or an external impact is applied to the golf ball. In addition, since the case has a large size so as to be burdensome, the case may frequently interfere with a golf swing, so that use of the case has been frequently avoided.

As shown in FIG. 6, according to the present invention, a height h2 from a bottom of the annular protrusion part 351 facing the inner surface of the lower case 100 to a longitudinal end of each of the pair of elastic support parts 310 and 320 may be preferably greater than a radius r1 of the golf ball 10 (h2>r1), and a distance D1 between the longitudinal ends of the pair of elastic support parts 310 and 320 may be preferably less than a diameter (D=2×r1) of the golf ball 10 (D1<D). In addition, as shown in FIG. 7, a distance D2 between longitudinal ends of the two covers 210 and 220 may be preferably greater than or equal to the diameter (D=2×r1) of the golf ball.

Since the distance D2 between the longitudinal ends of the two covers 210 and 220 is greater than or equal to the diameter (D=2×r1) of the golf ball, the golf ball 10 may smoothly pass through a portion between the two covers 210 and 220 so as to be fitted between the pair of elastic support parts 310 and 320, and since the distance D1 between the longitudinal ends of the pair of elastic support parts 310 and 320 is less than the diameter (D=2×r1) of the golf ball 10, and the height h2 to the longitudinal end of each of the pair of elastic support parts 310 and 320 is greater than the radius r1 of the golf ball 10, once the golf ball 10 is fitted between the pair of elastic support parts 310 and 320, the golf ball 10 may be firmly gripped above a center line HL of the golf ball 10 by elasticity of the pair of elastic support parts 310 and 320, so that the golf ball 10 may be more stably fixed within the golf ball holder 300.

Meanwhile, gripping parts 311 and 321 protruding toward the golf ball 10 to grip the outer surface of the golf ball 10 may be preferably formed at the upper ends of the pair of elastic support parts 310 and 320, respectively, and the gripping parts 311 and 321 may preferably extend from the upper ends of the elastic support parts 310 and 320 to both side ends of the elastic support parts 310 and 320, respectively. In addition, more preferably, inner surfaces of the elastic support parts 310 and 320 may be preferably formed as curved surfaces with a curvature that is equal to the radius r1 of the golf ball 10, and inner surfaces of the gripping parts 311 and 321 may be preferably formed as curved surfaces with a curvature r2 that is less than the radius r1 of the golf ball 10. In this case, the golf ball 10 may be gripped more firmly by the gripping parts 311 and 321, and may be stably gripped even when a force for separating the golf ball 10 to an upper side or a lateral side is applied after the golf ball 10 is gripped.

Meanwhile, when the golf ball 10 is stored in the case for the golf accessories, a lower portion of the golf ball 10 may be preferably ensured to make close contact with the inner surface of the lower case 100 as much as possible. When the lower portion of the golf ball 10 makes close contact with the inner surface of the lower case 100 as much as possible as described above, the height of the case for the golf accessories may be decreased so that an overall size of the case for the golf accessories may be compact. Therefore, the present invention may provide a method for determining a specific size of the seating groove 350, so that the lower portion of the golf ball 10 may make close contact with the inner surface of the lower case 100 as much as possible when the seating groove 350 is formed in the golf ball holder 300. In other words, when a thickness of an inner circumferential surface of the annular protrusion part 351 formed on the circumference of the seating groove 350 is T, and the diameter of the golf ball is D (the radius is r1), an inner diameter W of the seating groove 350 may preferably have a size satisfying a calculation formula W=2×√{square root over (DT−T²)}. In this case, the thickness T of the inner circumferential surface of the annular protrusion part may refer to a height from the bottom surface of the golf ball holder 300 to a longitudinal end of the annular protrusion part as shown in FIG. 6.

The formula for calculating the inner diameter W of the seating groove described above may be derived from a relation formula

$r 1 = \frac{W^{2} + 4 T^{2}}{8 T}$

that expresses a relation among a radius r1 of an arc, a length W of a chord, and a height T of the arc,

- in which since r1=D/2,

$\frac{D}{2} \times 8 T = W^{2} + 4 T^{2},$

- which becomes W²=4DT−4T²,
- so that W=2×√{square root over (DT−T²)}.

Therefore, when the formula W=2×√{square root over (DT−T²)} is satisfied, the lower portion of the golf ball 10 may make close contact with the inner surface of the lower case 100 as much as possible.

Meanwhile, FIG. 8 is a view showing a state in which the golf ball is pushed toward one elastic support part 320 when the golf ball is taken out from the case for the golf accessories according to the present invention (the section of the portion C-C′ of FIG. 2). According to the present embodiment, the two arc-shaped protrusions 161 and 162 may be provided. As described above, the lower case 100 included in the case for the golf accessories according to the present invention may include one annular protrusion 160 and two arc-shaped protrusions 161 and 162, which are formed on the inner surface of the lower case 100, so that the rear surface of the golf ball holder 300 may be seated in the inner surface of the lower case 100 while making contact with the inner surface of the lower case 100, in which the two arc-shaped protrusions 161 and 162 may face each other based on the annular protrusion 160. In addition, the golf ball holder 300 may include: the seating groove 350 opened in a circular shape at the center of the bottom surface of the golf ball holder 300, so that the golf ball 10 may be seated in the center portion of the golf ball holder 300; and the annular protrusion part 351 protruding toward the lower case 100 along the circumference of the seating groove 350, so that the seating groove 350 may be fitted and coupled to the inner circumferential surface of the annular protrusion 160, and the insertion parts 361 and 362 having the arc-shaped grooves 361a and 362a into which the arc-shaped protrusions 161 and 162 may be fitted may protrude from the positions corresponding to the arc-shaped protrusions 161 and 162 on the rear surface of the golf ball holder 300, respectively. Therefore, as shown in FIG. 8, when the golf ball 10 is pushed toward the elastic support part 320 on one side to take out the golf ball 10, the elastic support part 320 may be pushed (a red circle A1), whereas the elastic support part 310 on an opposite side may not be moved because the arc-shaped protrusion 161 is fitted to the arc-shaped groove 361a, so that a gap may be generated between the golf ball 10 and the elastic support part 310 (a red circle A2), and thus the golf ball 10 may be easily separated from the golf ball holder 300.
