Description

Technology Field

[0001] The present invention relates to a park golf ball pickup device capable of setting up a park golf ball recovered from a hole cup, and more specifically, to a park golf ball pickup device capable of setting up a park golf ball recovered from a hole cup, which allows the park golf ball that has entered the hole cup to be easily recovered, as well as allowing the recovered park golf ball to be easily set up on the ground so as to be gripped by an elastic gripping rod. Background Technology

[0003] Park golf is a compound word of Park and Golf, and it is a leisure sport that combines elements of the game of golf with a park, which is a communication space, for the purpose of improving the health, recreation, and emotional life of the public or residents, and can be played on a small plot of land adjacent to a residence.

[0004] Park golf is a golf-based game and is a sports activity that can be enjoyed by people of all ages and genders, including three-generation families ranging from children to the elderly, couples, office workers, and people with disabilities.

[0005] Park golf is similar to golf in terms of gameplay but has the advantage of being easily accessible to anyone due to its shorter playing time, which reduces physical strain, and the fact that it is not significantly constrained by equipment or time. As a result, it can be enjoyed by people of all ages and genders, and is particularly popular among the elderly who require a certain level of physical activity.

[0006] However, just like golf, in park golf, you have to bend your waist and other parts of your body to retrieve the golf ball that has gone into the hole, which is a burden for the elderly.

[0007] Accordingly, Korean registered patent No. 10-2080406 proposes a golf ball retriever for park golf with a structure in which a grip part is installed to allow a ball to be inserted and held on a telescopic rod structure that can extend or retract in length.

[0008] Conventional ball retrieval devices adjust the length of the rod to suit the user's height, allowing the user to retrieve the ball from inside the hole with minimal bending of the waist. However, unlike general golf courses, the places where park golf is played do not have much grass planted, so muddy areas occur after rain. Consequently, mud or foreign substances get on the park golf balls while playing. When picking up the park golf ball from the hole cup with a conventional ball retrieval device and then removing the ball from the device, problems arise where foreign substances get on gloves or hands. Furthermore, the user must perform a bending motion when setting down the park golf ball, which acts as a factor that increases physical burden. Therefore, there is an urgent need to develop equipment that can solve these problems. The problem to be solved

[0010] The present invention was conceived in consideration of the above-mentioned circumstances, and the objective of the present invention is to provide a park golf ball pickup device capable of setting up a park golf ball retrieved from a hole cup, which allows the park golf ball that has entered the hole cup to be easily retrieved by the elastic gripping rod, and when the retrieved park golf ball held by the elastic gripping rod is placed on the ground and pressed, the park golf ball held by the elastic gripping rod is detached from the elastic gripping rod by the elastic return force of the one-touch withdrawal part to set up. means of solving the problem

[0024] As illustrated in FIGS. 1 to 13 above, a park golf ball pickup device capable of setting up a park golf ball recovered from a hole cup according to the present invention is a pickup device configured to recover a park golf ball (40) that has entered a hole cup, and comprises a grip mounting rod (100) mounted on the grip, a plurality of elastic gripping rods (200) formed on the upper side of the grip mounting rod (100) to grip and recover a park golf ball (40) contained in a hole cup, and a one-touch withdrawal part (300) installed to be inserted into an insert insertion groove (101) of the grip mounting rod (100) to withdraw the park golf ball gripped by the elastic gripping rods (200) by elastic return force.

[0025] That is, the park golf ball pickup device capable of setting up a park golf ball retrieved from a hole cup according to the present invention allows the park golf ball contained in the hole cup to be easily retrieved without bending over while playing park golf, and when playing golf on the next hole, if the park golf ball held in the elastic gripping rod is pressed against the ground, it is pulled out from the elastic gripping rod by the one-touch extraction part (300) so that the park golf ball can be easily positioned at a predetermined setup position.

[0026] First, a grip (10) is installed on a golf club for park golf to prevent the hand from slipping during a golf swing, and it should be noted that this grip is installed to wrap around the upper side of the shaft of the golf club.

[0027] The above grip mounting rod (100) is provided to be mounted on the grip (10) of a park golf club, and in order to mount the grip mounting rod (100), it is preferable to pre-form an expansion hole (30) of a width that allows the grip mounting rod (100) to be inserted into the grip (10).

[0028] That is, the hole formed on the upper surface side of the grip (10) of the park golf club is formed to have a significantly small diameter for inserting the grip mounting rod (100) according to the present invention, and thus the expansion hole (30) is formed in advance so that the grip mounting rod (100) can be inserted to mount the grip mounting rod.

[0029] At this time, an insert insertion groove (101) of a predetermined length is formed in the grip mounting rod (100) from the upper side to the lower side, and the one-touch pull-out part (300), which will be described later, is fitted and coupled into this insert insertion groove (101).

[0030] Looking at the grip mounting rod (100) as one embodiment, it may be composed of a fitting body (110) that is fitted into the interior of the grip (10) through the expansion hole (30), a pointed part (120) formed such that the outer diameter gradually decreases as it goes downward from the lower side in the longitudinal direction of the fitting body (110), and an upper coupling member (130) formed on the upper side in the longitudinal direction of the fitting body with an outer diameter larger than the outer diameter of the fitting body (110).

[0031] Here, the sharp portion (120) is provided to allow the grip mounting rod (100) to be easily inserted into the interior of the grip through the expansion hole (30).

[0032] In addition, a hooking portion (111) is formed on the upper outer periphery of the fitting body (110), which is spaced downward at a predetermined distance from the upper coupling portion (130), so as to be hooked onto the upper inner surface of the grip (10).

[0033] That is, when the grip mounting rod (100) is inserted into the interior of the grip to a predetermined depth through the expansion hole (30), the locking member (111) is caught on the inner upper surface of the grip adjacent to the expansion hole, thereby preventing the grip mounting rod (100) from detaching from the grip during movements such as holding the golf club upside down, striking the ball, or carrying and moving the golf club.

[0034] In addition, a push remover hole (121) communicating with the insert insertion groove (101) is formed in the central portion of the lower longitudinal end of the grip mounting rod (100).

[0035] That is, the push remover hole (121) is formed to be in communication with the insert insertion groove (101) on the lower side surface of the sharp part (120), and when the one-touch pull-out part (300) is installed to be inserted into the insert insertion groove (101) and replacement is required due to malfunction or breakdown of the one-touch pull-out part, a rod of a predetermined length is pushed through the push remover hole (121) to remove the one-touch pull-out part (300) from the insert insertion groove (101) and install a new one-touch pull-out part.

[0036] In addition, the plurality of elastic gripping rods (200) are installed to be connected to the upper outer circumference in the longitudinal direction of the grip mounting rod (100), and are formed with a predetermined curvature while spaced apart from each other at a certain distance so as to be able to grip the park golf ball (40) inside the hole cup.

[0037] As an embodiment, the elastic gripping member (200) may be composed of a rib piece (210) formed at predetermined intervals along the outer circumference of the upper coupling member (130) and formed rounded with a predetermined curvature, and an open guide member (220) that allows the rib piece (210) to elastically spread out by sliding along the outer circumference of the park golf ball when gripping the park golf ball that has entered the hole cup.

[0038] That is, when the elastic gripping rod portion (200) is pushed into the hole cup to retrieve the park golf ball that has entered the hole cup, the open guide (220) slides along the outer circumference of the park golf ball, and the rod portion (210) is elastically spread to grip the park golf ball, and in such a state, when the golf club equipped with the pickup device of the present invention is lifted, the golf ball can be easily retrieved from inside the hole cup.

[0039] At this time, it is preferable that a predetermined gap (G) be formed between the park golf ball (40) held by the plurality of elastic gripping rods (200) and the upper end of the one-touch withdrawal part (300). This is to allow the one-touch withdrawal part (300) to be easily operated by the pressure action of the park golf ball (40) held by the elastic gripping rods (200), thereby enabling the withdrawal of the park golf ball (40) to be easily achieved. A detailed explanation of this will be provided later.

[0040] In another embodiment, the elastic gripping member (200) may be configured such that a pair is installed facing each other on the upper side of the grip mounting rod (100), and may consist of a pair of rib fitting pieces (240) that are fitted onto the outer circumference of the upper coupling member (130) of the grip mounting rod (100) at a mutually spaced distance, a gap forming piece (250) formed to extend upward from the rib fitting piece (240), a bending bending piece (260) formed to extend upward from the upper side of the gap forming piece (250) and bent to have a bend corresponding to the outer circumference of the park golf ball (40), and a hanging rib piece (270) formed to connect the upper ends of the bending bending piece (260).

[0041] In this way, the elastic gripping rib portion (200) is connected to the upper coupling member (130) by the rib fitting piece (240), so that in the long-term use of the pickup device according to the present invention, replacement is easily possible when replacement is required due to problems such as breakage or damage to the rib fitting piece (240), gap forming piece (250), bending bending piece (260), and hanging rib piece (270) forming the elastic gripping rib portion (200).

[0042] At this time, it is noted that by installing an elastic band (280) to wrap around the gap-forming piece (250) so as to prevent the external detachment of the rib fitting piece (240) fitted into the upper coupling member (130), the elastic gripping rib portion (200) can be prevented from detaching from the upper coupling member (130).

[0043] In addition, when the park golf ball (40) is gripped by the elastic gripping member (200) due to the gap forming piece (250), a predetermined gap (G) is formed between the park golf ball (40) and the upper end of the one-touch withdrawal part (300), thereby forming a section where the park golf ball (40) presses against the one-touch withdrawal part (300), making it easier to withdraw the park golf ball gripped by the elastic gripping member (200).

[0044] Meanwhile, the one-touch withdrawal unit (300) allows the park golf ball (40) held in the elastic gripping member (200) to be pushed outward by the elastic return force of the elastic spring (320) when the park golf ball (40) held in the elastic gripping member (200) is placed on the ground and pressed, thereby enabling the park golf user to set up the park golf ball at a predetermined position without bending their waist.

[0045] That is, the one-touch withdrawal part (300) is installed such that the lower longitudinal side of the operating stick (330) is connected to an elastic spring (320) installed inside a case (310) inserted into the insert insertion groove (101), and the upper longitudinal side of the operating stick (330) is configured to protrude a predetermined length into the interior of the elastic gripping rod part (200). When a park golf ball (40) is inserted into the interior of the elastic gripping rod part (200), the operating stick (330) is inserted into the interior of the case (310) and its protrusion outside the case is restricted. When the park golf ball (40) located inside the elastic gripping rod part (200) is pushed in the direction of the grip mounting rod (100), the protrusion restriction state of the operating stick (330) is released, and the restoring force of the elastic spring (320) causes the It is configured so that a park golf ball (40) located inside the elastic wave propeller section (200) can be withdrawn.

[0046] Looking at the one-touch withdrawal unit (300) as an embodiment, the one-touch withdrawal unit (300) comprises: a case (310) installed to be inserted into the insert insertion groove (101) and having a receiving space formed inside; an elastic spring (320) installed to be inserted into the case (310); an operating stick (330) formed such that its lower longitudinal side is connected to the elastic spring (320) and its upper longitudinal side protrudes into the inner side of the elastic gripping rod (200), with a stick-catching end (331) formed on its upper outer periphery to catch on the top of the case (310); a catch-elastic body (340) installed with one end fixed to the outer periphery of one side in the width direction of the operating stick (330); and a structure provided to be located inside the case (310) such that when the operating stick (330) moves downward, the catch-elastic body (340) It may be configured to include a heart cam (350) in which the other end is caught to restrict the protrusion of the operating stick (330).

[0047] At this time, the above-mentioned locking elastic body (340) may be configured to include a fitting leg (341) that is fixedly fitted onto the operating stick (330), an elastic coil part (342) formed so that one side is connected to the fitting leg (341), an extension stick (343) that extends downward from the other side of the elastic coil part (342), and a bending locking piece (344) formed to be bent toward the heart cam (350) from the lower side of the extension stick (343).

[0048] Additionally, an opening (311) is formed on one side in the width direction of the case (310), a cover (360) is mounted on the opening (311), and a heart cam (350) is formed to protrude from the inner surface of the cover (360).

[0049] When examining the operating state of the one-touch withdrawal unit (300) configured as described above, when a park golf ball (40) is inserted into the inner side of the elastic gripping rod unit (200), the operating stick (330) slides inward toward the inner side of the case (310), and the elastic spring (320) is compressed.

[0050] At this time, as the bending locking piece (344) of the locking elastic body (340) moves along the inclined outer circumference of the heart cam (350), torsional energy is stored in the elastic coil part (342), and subsequently, the bending locking piece (344) is seated in the restraining groove (351) provided on the lower side of the heart cam (350), thereby restricting the protrusion of the operating stick (330).

[0051] In this state, when the user presses the park golf ball (40) located on the elastic gripping member (200) against the ground, the bending catch piece (344) seated in the restraining groove (351) of the heart cam (350) is disengaged from the restraining groove (351) by the restoring force of the elastic coil member (342), and subsequently, the operating stick (330) pushes the park golf ball (40) by the elastic return force of the elastic spring (320) so that it can be disengaged from the elastic gripping member (200).

[0052] Additionally, on the upper outer periphery of the above case (310), a catch-fit piece (312) is formed to engage with a close-fit installation groove (131) formed to have a predetermined depth on the upper surface of the grip mounting rod (100).

[0053] That is, when the one-touch withdrawal part (300) is inserted into the insert insertion groove (101) and installed, the insertion depth of the case (310) is limited by the catch-fit piece (312) that engages with the close-fit installation groove (131), thereby enabling smooth operation of the operating stick (330).

[0054] In addition, when an expansion hole (30) is formed in the grip (10) for mounting a grip mounting rod (100), a hole expansion cutter (400) is used in the present invention, and the hole expansion cutter (400) is formed so that the expansion hole (30) does not deviate from the center of the grip (10).

[0055] As one embodiment, the hole expansion cutter (400) may be configured to include a hole processing cutter (410) having a circular cutter blade (411) formed on one side in the longitudinal direction, an insert nut (420) fixedly installed on the other side in the longitudinal direction of the hole processing cutter (410), and a wedge member (430) installed to be inserted to a predetermined depth in the inner direction from one side in the longitudinal direction of the hole processing cutter (410), with a sharp end formed to protrude to the outside of the hole processing cutter (410).

[0056] When examining the usage state of the hole expansion cutter (400) configured in this manner, the sharp end of the wedge (430) is inserted into the hole (11) formed in the grip (10) and positioned, and then a manual or automatic tool is connected to the insert nut (420) to rotate the hole processing cutter (410). As the wedge (430) is drawn into the interior through the hole (11), it is initially centered, and subsequently, the hole processing cutter (410) cuts the upper surface of the grip (10) in a circular manner to form an expansion hole (30) that does not deviate from the center of the grip (10).

[0057] In addition, a slip prevention member (140) that is in close contact with the inner surface of the shaft (20) of the golf club wrapped by the grip may be installed on the outer circumference of the fitting body (110) of the grip mounting rod (100), spaced apart from each other at a certain distance in the vertical length direction.

[0058] At this time, a groove (141) for installing a slip prevention device (140) can be formed along the circumference of the fitting body (110) of the grip mounting rod (100) to a predetermined depth so as to allow the slip prevention device (140) to be installed.

[0059] When the grip mounting rod (100) having the above-mentioned anti-slip member (140) formed thereon is inserted into the interior of the grip, the anti-slip member adheres to the inner surface of the shaft (20) located inside the grip, thereby preventing the up-and-down slip of the grip mounting rod (100).

[0060] Although specific embodiments of the present invention have been described in detail as above, those skilled in the art will be able to make various modifications without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the embodiments described above, but should be defined by the claims set forth below as well as equivalents thereof.
