Title: Golf ball marker having clip part

Description:
TECHNICAL FIELD 
     The present disclosure relates to a golf ball marker having a clip part, and more particularly, to a golf ball marker, which is configured in a clip shape to be capable of being selectively attached to/detached from a pocket, a belt, a visor, or head, and which is capable of indicating the position of a golf ball upon being fixed to the ground of a golf course. 
     BACKGROUND ART 
     When enjoying golf at a field golf course, players hit a golf ball from a tee box or fairway to land upon a green with a hole cup. When several players play on the green landed thereby, each golf player indicates the position of his/her golf ball to be putted by placing a golf ball marker at the green position where the golf ball has been landed such that the golf ball normally does not interfere with the other players&#39; putting. 
     Such golf ball markers are generally manufactured in the form of coins, but there is a problem in that the golf ball markers may not be easily recognized on an inclined green or at the opposite side with respect to the hole cup due to the relatively thin thickness thereof. 
     In order to solve such a problem, Korean Patent No. 10-1042518 (published on Jun. 17, 2011) discloses a technique for golf ball markers. The prior art golf ball marker includes a plate-shaped body having a predetermined thickness, a direction-indicating needle hinged at one end thereof to the upper portion of the body to indicate the direction of the hole cup from a position where the ball is placed, a pivot member that allows the direction-indicating needle to be pivotally coupled to the body, and a weight member coupled to the lower portion of the body via multiple support pins to support the ball marker such that the ball marker does not move when the ball marker is placed on the green. The golf ball marker having such a configuration is advantageous in that the golf ball marker is able to accurately indicate the direction from the golf ball placed on the green to the hole cup, allows a situation such as a green slope to be quickly grasped, and is easily visible even from the opposite side with respect to the hole cup. 
     However, the golf ball marker proposed in this prior art still requires improvement in terms of the following points, and constant development is demanded. 
     For example, the weight itself for preventing movement on the green has an advantage in preventing movement, but is accompanied by a disadvantage in carrying due to its heavy weight. Further, the golf ball marker is poor in the convenience of carrying and use since the golf ball marker is not provided with a structure or configuration that allows the golf ball marker to be easily fixed to a user&#39;s body, clothes, or a bag or to be easily detached for use. 
     In addition, the structure in which the direction-indicating needle pivots upwards with respect to the body is improved in visibility compared with the conventional thin coin type golf ball marker in that it can be confirmed from anywhere on the green. However, when the amount of sunshine is small, for example, on a cloudy day, early morning, or sunset, the golf ball marker is also difficult to recognize like the prior art golf ball marker, and thus a structural improvement or a configuration addition to secure visibility is required. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Technical Problem 
     An aspect of the present disclosure is to provide a golf ball marker with a clip part, which is configured to be easily and quickly attachable to/detachable from a body, clothes, or a bag and in which the longitudinal direction of the golf ball marker is capable of being firmly and easily installed and fixed in the vertical or horizontal direction with respect to the ground of a golf course and the visibility of the golf ball marker is capable of being further enhanced at a position where the position of the golf ball is indicated. 
     Technical Solution 
     In view of the above, a golf ball marker may include: a clip part including a curved elastic body elastically deformed while a curved shape thereof is reversed in response to an external force applied thereto, and a pressing piece connected to an end of the curved elastic body to be spaced apart from the curved elastic body or to come into compressive contact with the curved elastic body, the clip part being selectively attached to or detached from a fixed portion and being used as a marker; and a fixing portion protruding from one side of the clip part to fix the clip part to a ground of a golf course. 
     The curved elastic body may include a pair of elastic pieces disposed to be spaced apart from each other to form a hollow portion therebetween, the pair of elastic pieces joining at at least one end thereof in a twisted state to form a curved shape. 
     The fixing portion may be configured such that: at least one fixing portion protrudes outwards from a connection portion between the curved elastic body and the pressing piece in a longitudinal direction of the clip part such that the clip part is installed and fixed in a vertical direction with respect to the ground of the golf course; or at least one fixing portion protrudes from the pressing piece in a vertical direction with respect to a longitudinal direction of the clip part such that the clip part is installed and fixed in a horizontal direction with respect to the ground of the golf course. 
     An indication part may be coupled to the curved elastic body of the clip part to improve visibility of the clip part installed on the ground of the golf course to indicate a position of a golf ball, and the indication part may be formed in a character shape obtained by representing an insect such as a butterfly or an animal. 
     The indication part may have an LED lamp mounted on one side thereof. 
     A golf ball marker may include: a clip part including a curved elastic body elastically deformed while a curved shape thereof is reversed in response to an external force applied thereto, and a pressing piece connected to an end of the curved elastic body to be spaced apart from the curved elastic body or to come into compressive contact with the curved elastic body, the clip part being selectively attached to or detached from a fixed portion and being used as a marker; and a coin-shaped indication part provided on the clip part to improve visibility of the clip part installed on the ground of the golf course to indicate a position of a golf ball. 
     The curved elastic body may include a pair of elastic pieces disposed to be spaced apart from each other to form a hollow portion therebetween, the pair of elastic pieces joining at at least one end thereof in a twisted state to form a curved shape. 
     The fixing portion may be configured such that: at least one fixing portion protrudes outwards from an outer peripheral surface of the indication part in a longitudinal direction of the clip part such that the clip part is installed and fixed in a vertical direction with respect to the ground of the golf course; or at least one fixing portion protrudes from the bottom surface of the indication part in a vertical direction with respect to a longitudinal direction of the clip part such that the clip part is installed and fixed in a horizontal direction with respect to the ground of the golf course. 
     The indication part may have an LED lamp mounted on one side thereof. 
     The golf ball marker may further include a bottom support detachably coupled to the indication part. The bottom support may include: a body having an accommodation groove formed to pivotally accommodate the indication part therein; stroke scales formed on a top surface of the body along an edge of the accommodation groove in order to indicate a rotation degree of the clip part with respect to a hole cup in a state in which the clip part is positioned to indicate a stroke direction of a putter determined depending on a lie of a green of the golf course; and a magnetic body embedded in a center of the accommodation groove to fix the indication part with a magnetic force. 
     The body may further include an inclined direction indication part on the top surface thereof so as to allow an inclined direction of the green to be intuitively recognized, and the inclined direction indication part may include an annular groove formed in a ring shape along an edge of the accommodation groove in a state of being opened upwards, and a luminous ball configured to move due to its own weight in a state of being accommodated in the annular groove and to indicate the inclined direction. 
     The elastic pieces may have distance measurement scales formed on a surface thereof, so that a user is able to measure a distance to the hole cup based on a size of a hole cup flag when the user looks at the hole cup flag through the hollow portion at a middle or long distance. 
     The indication part may have a distance measurement sensor mounted on one side thereof so as to allow a distance to a hole cup within a short distance to be easily determined, and the LED lamp may change the color thereof depending on the distance to the hole cup in cooperation with the distance measurement sensor. 
     The clip part may include at least one of a first hole cup sight having protrusions repeatedly protruding from an elastic piece along a longitudinal direction thereof towards the hollow portion so as to set a putting line depending on a hole cup number determined depending on a lie of a green of the golf course, and a second hole cup sight having circular, elliptical, or polygonal perforations arranged at equal intervals in a central portion of the pressing piece in a longitudinal direction thereof. 
     Advantageous Effects 
     According to the present disclosure, since a clip part is provided to be capable of being easily and quickly attached to and detached from a fixed portion such as a pocket, a belt, a visor, or head, and the clip part itself has a function as a golf ball marker that is capable of being used for indicating the position of a golf ball by itself, the convenience in carrying and use can be improved. 
     In addition, since the clip part is firmly and easily fixed such that the longitudinal direction thereof is oriented in the vertical direction as well as the horizontal direction with respect to the ground of the golf course, it is possible to improve the visibility of the position of the golf ball even at a long distance. Furthermore, when an indication part having a creative character shape is coupled to the clip part, there is an effect that the visibility is further improved with the discrimination. 
     Accordingly, the user is able to solve the inconvenience of walking back and forth in order to confirm the position of the golf ball, and it is possible to easily grasp the slope or lie of the green in golf rounding in which immediate determination is important. Therefore, it is possible to promote the convenience in rounding and the improvement in athletic performance.

     Upper (upper side), lower (lower side), left and right (side or lateral side), front (front side), rear (rear side), and the like designating directions in the description of disclosure and the claims are determined based on the relative positions between drawings or components for convenience of explanation, rather than limiting the scope of protection. Each of the directions described below is based on this, unless otherwise specifically limited. 
     A golf ball marker  100  or  200  having a clip part according to the present disclosure includes a marker and an attachment part, which are integrated with each other in order to improve upon the inconvenience of a conventional coin type marker, which is attached to a separate attachment part and is then attached to a belt or the like. This integration is intended to improve portability and convenience of the golf ball marker  100  or  200 . 
     In addition, the golf ball marker  100  or  200  of the present disclosure has been conceived in order to solve the problem that the conventional coin type markers are poor in visibility at a point where the position of the golf ball is indicated due to the thin thickness thereof, through the fundamental and simple change of conception (for each of the following components), and to enable immediate acquisition of information necessary for rounding. 
     First Embodiment 
     In order to execute the functions or actions described above, as illustrated in  FIG. 1A , a golf ball marker  100  having a clip part according to a first embodiment of the present disclosure includes a clip part  110  and fixing portions  120   a  and  120   b , and further includes an indication part  130  for ensuring visibility. 
     Each of the above-described configurations will be described in detail as follows. 
     The clip part  110  is a component configured to be rapidly fixed to a fixed portion such as a pocket, a belt, a visor, or head and used as a means for indicating the position of a golf ball by being rapidly detached from the fixed portion, and includes a curved elastic body  112 , a pressing piece  114 , etc. 
     The curved elastic body  112  is a component bent in a bow shape in which a curved shape is reversed in opposite directions due to an external force to exert an elastic force, and includes a pair of elastic pieces  112   a ,  112   b  spaced apart from each other such that a hollow portion S is disposed in the central portion therebetween and joined together in a twisted state at at least one of the opposite ends thereof so as to form a curved shape and to exert an elastic force corresponding to the degree of twist. 
     At this time, since the pair of elastic pieces  112   a  and  112   b  are joined together in the state of being twisted, a torsional stress is applied to the facing inner regions of the elastic pieces  112   a  and  112   b , and when the curved elastic body  112  is deformed with an external force equal to or higher than the corresponding stress, the curved elastic body is bent in opposite directions while the twist direction is reversed with reference to the inner regions of the elastic pieces  112   a  and  112   b , particularly the central portion. 
     The pressing piece  114  is a component that forms an insertion space I while being spaced apart from the curved elastic body  112  in the direction of moving away from the curved elastic body  112  in the state of being connected to one end of the curved elastic body  112 , and that exerts a fixing force while being in compressive contact with the curved elastic body  112  when the curved elastic body  112  is bent and deformed in the direction in which the curved elastic body  112  approaches the pressing piece  114 . 
     The pressing piece  114  is formed to be parallel to the longitudinal direction of the curved elastic body  112  to form the above-described insertion space I or to exert the fixing force and has a bent portion  114   a  concavely bent toward the curved elastic body  112  at the central portion thereof in order to increase the above-mentioned fixing force. The pressing piece  1143  is provided with at least one elongated hole such that, when the curved elastic body  112  is bent and deformed to approach the pressing piece  114 , the pressing piece  114  can exert a soft elastic force. In addition, the width of the free end portion of the pressing piece  114  is preferably larger than the width of the hollow portion S such that the pressing piece  114  is not inserted into the hollow portion S. 
     The curved elastic body  112  and the pressing piece  114  may be integrally manufactured through a process of cutting and bending a plate-shaped metal member through press working, or may be integrally manufactured through injection molding using a synthetic resin. 
     A user may easily and rapidly attach or detach the golf ball marker  100  according to the present disclosure to or from a pocket or the like through the clip part  110  having the structure described above. 
     That is, the user may conveniently and easily carry the golf ball marker  100  according to the present disclosure in the state of being attached to a pocket, head, or the like by applying a unidirectional external to the curved elastic member  112  to form the insertion space I, then causing one side of a visor, a belt, or head as shown in  FIG. 2A  to be positioned in the insertion space I, and then applying an external force to the curved elastic body  112  in the other direction such that a fixing force is exerted by the pressing piece  114 . Then, the user may remove the golf ball marker  100  according to the present disclosure in reverse order to the above-described method, and may use the golf ball marker  100  to indicate the position of the golf ball. 
     In addition, since the clip part  110  has a predetermined volume and is formed to be elongated in a direction, the clip part  110  may sufficiently perform a role similar to that of a conventional marker by itself. When the clip part  110  is positioned such that the free end side of the curved elastic body  112  and the pressing piece  114  (the side at which the clip part  110  is opened or closed) is directed to a hole cup  10  or a putting line PL while indicating the position at which the golf ball is placed, the putting play can be advanced quickly. 
     The fixing portion  120   a  or  120   b  is a component provided to allow the clip part  110  to be firmly fixed without moving on the ground of a golf course. The fixing portion  120   a  or  120   b  protrudes outward from one side of the clip part  110  and is formed in the form of a pile, a pin, or a T-shaped or V-shaped pack as a whole, so that the fixing portion can be smoothly driven into the ground. 
     According to the first embodiment of the present disclosure, as illustrated in  FIGS. 1A and 2A , at least one fixing portion  120   a  or  120   b  protrudes outwards in the longitudinal direction of the clip part  110  from the connection portion  116  between the curved elastic body  112  and the pressing piece  114  such that the clip part  110  is installed and fixed in the vertical direction with respect to the ground of a golf course. In this case, it is preferable to provide four or fewer protruding fixing portions  120   a  and  120   b  in consideration of portability and visibility depending on the size of the clip part  110 , and  FIG. 1A  illustrates one fixing portion  120   a.    
     When the clip part  110  is fixed in the vertical direction with respect to the ground of the golf course through the fixing portion  120   a , it is possible to firmly fix the position compared to the case in which a conventional coin type marker is placed on the ground. Further, since the clip part remarkably protrudes upwards from the ground of the golf course by the length thereof, visibility is greatly improved such that it is possible to immediately confirm the point where the position of the golf ball is indicated, and based on this, it is possible to quickly establish game plan or the like required for golfing. 
     The indication part  130  is a component included in the clip part  110  to improve the visibility of the clip part  110  installed on the ground of the golf course to indicate the position of the golf ball, and any indication part  130  may be used as long as it includes a combination of characterful, distinctive, and decorative shapes, patterns, features, and colors and can be installed in the clip part  110  to further improve the visibility as a marker. 
     However, the indication part  130  according to the first embodiment of the present disclosure has a predetermined character shape. At this time, the predetermined character shape includes shapes of an animal such as a bear or a dog, a shape of an insect such as a butterfly or a bee, a movie character shape, a cartoon character shape, a geometric decorative shape, or the like. This shape may be colored appropriately, and a shiny material may be used on the surface in order to create an elegant appearance and to improve visibility and decoration. For example, in  FIGS. 1A and 2B , a character shape representing a butterfly is coupled to the upper surface of the clip part  110  to be used as the indication part  130 . 
     With this character shape, the golf ball marker  100  according to the present disclosure can be fully utilized as an accessory by being attached to a body, clothes, or a bag due to the enhanced decorative function as well as the improved visibility for a golf ball position. 
     According to a first modification to the first embodiment of the present disclosure, as illustrated in  FIG. 1B , at least one fixing portion  120   b  protrudes in the vertical direction with respect to the longitudinal direction of the clip part  110  from the pressing piece  114  such that the clip part  110  is installed and fixed in the horizontal direction with respect to the ground of a golf course. In this case, it is preferable to provide four or fewer protruding fixing portions  120   b  in consideration of portability and visibility depending on the size of the clip part  110 , and  FIG. 1B  illustrates one fixing portion  120   b.    
     When the clip part  110  is fixed in the horizontal direction with respect to the ground of the golf course through the fixing portion  120   b , it is possible to firmly fix the position compared to the case in which a conventional coin type marker is placed on the ground. Further, since the clip part protrudes upwards from the ground of the golf course by the thickness thereof, visibility is improved such that it is possible to immediately confirm the point where the position of the golf ball is indicated, and based on this, it is possible to quickly establish a game plan or the like required for golfing. 
     As illustrated in  FIG. 1B , on the surface of the elastic pieces  112   a  and  112   b  according to the first modification to the first embodiment of the present disclosure, distance-measuring scales  118  are formed which make it possible to measure the distance to the hole cup  10  based on the size of the hole cup flag  11  when the user looks at a hole cup flag  11  through the hollow portion S at a middle or long distance (about 50 m to 200 m, which is a distance for using a wood or a sand wedge). 
     In this case, each indication line of the distance measuring scales  118  forms an indication line for each distance using the similarity ratio of viewing angles each forming a triangular shape as illustrated in  FIG. 5 . That is, based on the length of the hole cup flag  11  (h 1 , approximately 170 cm) and the spacing distance h 2  between the user&#39;s eye and the clip part  110  or  210  (arbitrarily set to about 30 cm to 90 cm), correlation (x, y) between the inter-scale length (an unknown x) and the distance to the hole cup  10  (an unknown number y) can be calculated through the calculation of a proportional equation. Since the calculation of the proportional equation is simple, a detailed explanation thereof will be omitted. 
     A method of using the distance measurement scales  118  or  218  formed on the elastic pieces  112   a  and  112   b  or  212   a  and  212   b  will be briefly described with reference to  FIG. 5 . First, an end portion (upper end portion or lower end portion) of the clip part  210  or the indication part  230  is lightly held, and the distance between the user&#39;s eye and clip part  210  (h 2 ) is adjusted to a preset distance (arbitrarily set to about 30 cm to 90 cm) while adjusting the user&#39;s viewing angle such that the hole cup flag  11  is visible through the hollow portion S. Thereafter, the ground scale  218   a  formed at the lower end among the distance measurement scales  218  is aligned with the lower end of the hole cup flag  11 , and then the distance to the hole cup  10  (y) is measured based on the scales (e.g., 50 m, 60 m, 75 m, 100 m, 150 m, and 200 m) formed in a region corresponding to the upper end of the hole cup flag  11 , which is visible through the hollow portion S. 
     These distance measurement scales  118  or  218  are not able to accurately measure the distance to the hole cup  10  as precisely as a complicated and bulky electronic measurement device, but there is benefit in that the distance to the hole cup  10  can be immediately and intuitively measured by merely forming the distance measurement scales on the clip part  110  or  210  having a simple structure and a small volume. 
     As a result, since it is not necessary to carry an expensive measuring apparatus separately, it is possible to improve the user&#39;s convenience, and since immediate measurement is enabled whenever necessary, it is possible to make a quick decision on club selection and the like, thereby enhancing athletic performance. When the distance measurement scales  118  or  218  are indicated on the clip part  110  or  210 , the indication part  130  or  230  is installed preferably to lean to the end of the clip part  110  or  210  so as not to interfere with the indication part  130  or  230 . 
     In addition, as briefly illustrated in  FIG. 1B , according to the first modification to the first embodiment of the present disclosure, one or more LED lamps  132  may be mounted on one side of the indication part  130  to be powered by a flat mercury battery  134 , and an on/off switch  136  may be provided on one side of the surface of the indication part  130 . The LED lamps  132  are provided to easily confirm or recognize a position where the golf ball is placed when the amount of sunshine is small, for example, on a cloudy day, early morning, or sunset. 
     Meanwhile, as illustrated in  FIG. 1C , according to a second modification to the first embodiment of the present disclosure, the clip part  110  includes a first hole cup sight  112   c , which repeatedly protrudes from the elastic piece  112  to the hollow portion S in the longitudinal direction of the elastic piece  112 . In this case, one protrusion of the first hole cup sight  112   c  corresponds to one hole cup number. 
     At this time, hole cup number refer to a method of numerically expressing a putting-target point determined by an advisor such as a caddy on the basis of a hole cup  10 . 
     The first hole sight  112   c  allows the user to easily set a putting line PL in accordance with the hole cup number determined depending on the lie of a green in the golf course, thereby providing the user with the convenience in landing upon the green. Here, the term “lie” is a term that encompasses conditions related to a position where a golf ball is stopped on a field, and the field is variously utilized on the basis thereof. 
     The usage of the first hole cup sight  112   c  will be described with reference to an enlarged view of  FIG. 7 . First, the user places the golf ball marker  110  according to the present disclosure in a lateral direction such that the hole cup  10  is correctly positioned between the protrusions formed on the first hole cup sight  112   c . Then, it is possible to simply indicate or set a putting line PL on the green by remembering the approximate angle between the position of a protrusion shifted by the hole cup number determined by a caddy or the user based on the lie of the green of the golf course (i.e., the putting line PL) and the position of the hole cup  10  (the hole cup line HL), and causing the clip part  110  to be directed to the corresponding angle while positioning the golf ball marker  100  according to the present disclosure at a position where the golf ball has been placed. 
     Second Embodiment 
     As illustrated in  FIG. 3A , a golf ball marker  200  having a clip part according to a second embodiment of the present disclosure includes a clip part  210  and a coin-shaped indication part  230  provided on the clip part  210 . Here, since the clip part  210  and the indication part  230  are similar to those described in the first embodiment, a detailed description thereof will be omitted, and only the distinctive differences therebetween will be briefly described. 
     First, the indication part  230  according to the second embodiment of the present disclosure is manufactured in a conventionally used coin shape and is installed at one end of the clip part  210  in order to further improve the visibility of the clip part  210 . At this time, a variety of patterns, and characters may be formed on the coin-shaped indication part  230  together with colors. 
     As illustrated in  FIG. 4 , when the golf ball marker  200  having a simple structure and shape according to the second embodiment of the present disclosure is horizontally placed on the ground of a golf course such that the longitudinal direction of the clip part  210  is directed to the hole cup  10  after deforming and bending the clip part  210  to be bent upwards, the visibility is improved due to the clip part  210 , which is deformed and bent upwards, so that a point where the position of the golf ball is indicated and the hole cup line HL can be immediately confirmed and a strategy necessary for rounding can be quickly established based thereon. In addition, since it is easy to pick up the clip part  210 , which is deformed and bent upwards, it is easy to recover the golf ball marker  200  according to the present disclosure. 
     Meanwhile, as illustrated in  FIG. 3B , the golf ball marker  200  according to the first modification to the second embodiment of the present disclosure may further include fixing portions  220   a  and  220   b  for securing a firm fixing force to the ground of the golf course, distance measuring scales  218 , a bottom support  240  configured to provide direction indication and inclination information, an LED lamp  232 , and the like. 
     Here, since the fixing portions  220   a  and  220   b  and the distance measurement scales  218  are similar to those described in the first embodiment, a detailed description thereof will be omitted, and only the distinctive differences therebetween will be briefly described. 
     First, one or more fixing portions  220   b  protrude in the vertical direction with respect to the longitudinal direction of the clip part  210  from the bottom surface of the indication part  230  such that the clip part  210  is installed and fixed in the horizontal direction with respect to the ground of the golf course. Although not illustrated in  FIG. 3B , of course, one or more fixing portions  220   a  may be provided on the outer peripheral surface of the indication part  230  to protrude in the longitudinal direction of the clip part  210  such that the clip part  210  is installed and fixed in the vertical direction with respect to the ground of the golf course. 
     As illustrated in  FIG. 3B , according to the first modification to the second embodiment of the present disclosure, the indication part  230  may include a distance measurement sensor  238  mounted on one side (preferably, on the clip part  210  side) in order to easily determine the distance to the hole cup  10  in a short distance (about 20 m). In the state of being mounted at appropriate positions exposed to the outside as in the first embodiment, one or more LED lamps  132  or  232  are implemented to change colors depending on the distance to the hole cup  10  (e.g., 20 m, 15 m, 10 m, 5 m, and 3 m) in cooperation with the sensor measurement sensor  238 . 
     The distance measurement sensor  238  and the LED lamp  232  may be powered by a flat mercury battery  234 , and an on/off switch  236  may be provided on one side of the indication part  230 . The LED lamp  232  may facilitate grasping the position of the golf ball even when the amount of sunshine is small, for example, on a cloudy day, early morning, or sunset. At the same time, the LED lamp  232  may immediately provide information on the distance to the hole cup  10  to the user through an intuitive color change. 
     Meanwhile, according to a second modification of the second embodiment of the present disclosure, the golf ball marker  200  may further include a bottom support  240 , as illustrated in  FIG. 3C . The bottom support  240  is detachably coupled to the indication part  230  of the golf ball marker  200  according to the second embodiment described above to perform additional functions. The bottom support  240  includes a body  242 , stroke scales  244 , and a magnetic body  246 . 
     The body  242  is a disc-shaped component having an accommodation groove  242   a  formed at a central portion thereof so as to pivotally accommodate the indication part  230  therein. At this time, an inclined direction indication part  250  including an annular groove  252  and a luminous ball  254  may be further provided on the top surface of the body  242 , so that the inclined direction of the green can be immediately and intuitively recognized. 
     The annular groove  252  is a component that is formed in a ring shape along the outer periphery of the accommodation groove  242   a  in an upwardly opened state. In the opened region, a cover ring made of a transparent material may be provided to cover the opened region so as to prevent the luminous ball  254 , which will be described later, from escaping from the accommodation groove  242   a . Alternatively, escape prevention protrusions protruding from one side of the opened region toward the center of the opened region may be formed. 
     The luminous ball  254  is a component that indicates the inclined direction while moving due to its own weight in the state of being accommodated in the annular groove  252 , and is manufactured as a spherical member having a diameter smaller than the width of the annular groove  252 . The user is able to intuitively and clearly confirm the inclined direction of the golf course even when the amount of sunshine is small, for example on a cloudy day, early morning, or sunset, through the luminous component of the luminous ball  254 . 
     The inclined direction indication part  250  described above immediately and clearly provides information on the inclined direction in golf rounding in which an immediate determination is important, thereby contributing to grasping the flow or lie of the green, and hence helping enhancing rounding convenience and athletic performance. 
     The stroke scales  244  are provided to indicate the rotation degree of the clip part  210 , which is positioned to indicate the stroke direction of a putter, with respect to the hole cup  10 , in which the stroke direction is determined depending on the lie of the green of the golf course, and the stroke scales  244  are formed on the top surface of the body  242  at regular intervals along the edge of the accommodation groove  242   a . In this case, for example,  36  stroke scales  244  in total may be provided such that each stroke interval indicate 10 degrees, and a hole cup scale  244   a  may be provided at any one side to be distinguished from other scales. 
     The method of using the stroke scales  244  is executed such that the bottom support  240  is placed on the ground of the golf course such that the hole scale  244   a  of the lower support  240  is directed to the hole cup line HL as illustrated in  FIG. 6 , and the indication part  230  is rotated such that the longitudinal direction of the clip part  210  and the putting line PL determined depending on the lie of the green (usually determined by degrees from the hole cup  10  to the left or right) coincide with each other. 
     When the longitudinal direction of the clip part  210  indicates the putting line PL visually clearly, actual putting may be immediately performed, and an own putting line PL may be modified or changed appropriately on the basis of the previously performed putting. 
     The magnetic body  246  is provided to allow the metal indication part  230  to be maintained at a rotated state without being easily separated from the bottom support  240 . The magnetic body  246  is embedded in the center of the accommodation groove  242   a  to fix the indication part  230  with a magnetic force. 
     As illustrated in  FIG. 3D , according to a third modification to the second embodiment of the present disclosure, the clip part  210  includes a second hole cup sight  214   c  consisting of circular, elliptical, or polygonal perforations, which are arranged at regular intervals in the central portion of the pressing piece  214  in the longitudinal direction thereof. At this time, the space between the perforations of the second hole cup sight  214   c  and one perforation corresponds to one hole cup number. Of course, the second hole cup sight  214   c  may be used in combination with the first hole cup sight  112   c  described above in the first and second embodiments. 
     Like the first hole cup sight  112   c , the second hole sight  214   c  allows the user to easily set a putting line PL in accordance with the hole cup number determined depending on the lie of a green in the golf course, thereby providing the user with the convenience in landing upon the green. 
     The usage of the second hole cup sight  214   c  will be described with reference to an enlarged view of  FIG. 7 . First, the user places the golf ball marker  100  according to the present disclosure in a lateral direction such that the hole cup  10  is correctly positioned in a perforation formed in the second hole cup sight  214   c . Then, it is possible to simply indicate or set a putting line PL on the green by remembering the approximate angle between the position of a perforation or a space between perforation shifted by the hole cup number determined by a caddy or the user based on the lie of the golf green (i.e., the putting line PL) and the position of the hole cup  10  (the hole cup line HL) and causing the clip part  110  to be directed to the corresponding angle while positioning the golf ball marker  100  according to the present disclosure at a position where the golf ball has been placed. 
     In addition, when the golf ball marker  200  according to the third modification to the second embodiment of the present disclosure is used together with the bottom support  240 , the putting line PL may be simply indicated or set on the green by causing the hole cup scale  244   a  to be directed to the hole cup line HL, then remembering the approximate angle between the putting line PL and the hole cup line HL through the second hole cup sight  214   c , and then seating the golf ball marker  100  in the accommodation groove  242   a  while positioning the clip part  210  so as to reflect the angle with respect to the hole cup scale  224   a.    
     Of course, among the components described in the second embodiment of the present disclosure, any component, which has not been described in the first embodiment, is capable of being applied to the first embodiment. 
     Although the specific embodiment of the present disclosure has been described above, it is apparent to those skilled in the art that the present disclosure is not limited to the embodiment disclosed herein and various modifications and changes can be made without departing from the spirit and scope of the present disclosure. Therefore, such modifications and changes should not be individually construed from the spirit or point of view of the present disclosure, and it should be understood that modified embodiments belong to the claims of the present disclosure. 
     INDUSTRIAL APPLICABILITY 
     According to a golf ball marker having a clip part according to the present disclosure, since a clip part, which can be easily and quickly attached to or detached from on a fixed portion such as a pocket, a belt, a visor, or head, and which can be used for indicating the position of a golf ball by itself, is provided, the convenience in carrying and use is improved. Since the longitudinal direction of the clip part is firmly fixed in the vertical direction as well as the horizontal direction with respect to the ground of the golf course, the visibility of the position of the golf ball is improved even at a long distance, thereby improving the rounding convenience and athletic performance. By overcoming the limit of the existing technique in this way, the present disclosure can be used in the related art, and the possibility of commercialization or marketing of apparatuses to which the present disclosure is applied is sufficient. Further, it is clear that the present disclosure can be practically executed. Thus, the present disclosure is an industrially available disclosure.
