Abstract

To solve problems in which, conventionally, when several golf clubs selected and drawn out of a caddie bag are held by hand for movement in the round at a golf course, club shafts are intertwined with each other and it is hard to be carried, and one of the inside almost falls and the fingers might be pinched, and also, when aiming at a cup by using a putter on a green, the golf clubs being not used are laid and placed on a circumferential edge of the green, and therefore the grips of the golf clubs get wet when the turf gets wet, and the clubs other than the putter carrying in hand and used for cup-in might be misplaced.SOLUTION: A golf club carrying tool of the present invention is provided for holding multiple golf clubs by using a holder, and is functionalized as a grip part by making this holder into a substantially cylindrical shape. Also, an anchor pin 14 is made to conform in the cylindrical shaft extension direction of this holder part, and extended and fitted, and further is pushed in the ground of a golf course, and thereby a holding part 12 holding the golf clubs can be brought into self-standing.SELECTED DRAWING: Figure 10

Description

The present invention relates to a tool for carrying a golf club by holding several golf clubs in one hand. The golf club has an effect of improving visibility by making the golf club independent and preventing forgetting to collect the golf club after playing. Regarding the carrier.

The golf club carrier of the present invention is a golf that a self-player without a caddy at a golf course, which has been increasing in recent years, selects and carries several golf clubs to capture the green and brings them around the green. It is a tool for carrying a golf club that emphasizes the purpose of placing a club and playing. In particular, a golf club carrier devised in view of the frequent forgetting to collect golf clubs placed around the green after cup-in.

It is thought that the background to the increase in self-players in recent years is the aging of golf players and the increase in play by like-minded friends instead of golf play whose main purpose is entertainment.
According to Non-Patent Document 1 and Non-Patent Document 2, the number of golfers artificial in 2015 was 7.6 million, of which about 48% were 60 years old or older. There is also a need to improve the management style to reduce the cost of golf itself. Here, the increase in the number of self-players of elderly people who have retired from active duty is considered to be a factor in the increase in misplacement of golf clubs and the like due to forgetfulness due to aging peculiar to elderly people. Conventionally, as a means of transporting a group of golf clubs around the green in such self-play, several are bundled by hand, or they are carried in a so-called second bag that can accommodate several to six, or resin. It was made of plastic with a clip-shaped golf club holder and was bundled and carried around.

When transporting golf clubs by bundling them by hand, if three of them are bundled by hand, the golf club shaft 2 will be grasped by hand near the head 1 of the golf club as shown in FIG. It may rub against each other, scratch the surface of the shaft, and cause damage such as bending or breaking starting from the scratch. Further, if the center of gravity of the golf club is not firmly held, an unbalanced golf club may hang down as shown in FIG. 1, and a gap 4 is created between the golf clubs, and a finger or a glove is pinched there. Things can happen. Furthermore, the golf clubs that are carried have no choice but to lay the golf clubs that are not used for the latest play around the green. Since the grass is wet in early morning play and after rain play, the grip 3 will get wet when the golf club is laid down, and it will interfere with the play, so the work to remove the water from the grip 3 Is newly generated, which causes a delay in the progress of play.

Furthermore, since the laid golf club is inconspicuous, the putter used for the cup-in may be held in the hand and headed toward the golf cart, leading to forgetting to collect the laid golf club on the grass. In the case of play with a caddy, the caddy will notice it, but in the case of self-play, it is a manner that one of the friends will notice it. However, expecting that awareness with only elderly people cannot be expected in the same way that the frequency of forgetting to collect is increasing due to the increasing probability of forgetting due to aging.

In the case of the second bag, although it is small and lightweight, the weight of the bag is about 1 kg, and even if the weight of one golf club is 400 g, the total weight with the second bag is 2.2 kg to 3.4 kg. In addition, a caddy bag that houses a set of golf clubs will have a second bug, and it may not fit in the bag holder of a passenger golf cart for transportation that is generally used in golf courses. In addition, some of the second bags are of the type that are built into the caddy bag with several golf clubs stored, but the weight of the second bag containing several golf clubs is about 2.2 kg. The operation of putting a long second bag having a length of about 80 cm in and out of the caddy bag on a golf cart is not always an easy operation for an elderly person or a small woman.

In the case of a carrier having a clip-shaped holding function, if the clip-type cage 5 having a short length cannot accurately hold the center of gravity of the golf club, it is balanced as in the case of bundling by hand as shown in FIG. A golf club that cannot be removed will hang down. Further, even if the clip has a sufficient length as in Patent Document 2, the center of gravity of the golf club to which the long clip-type holder 6 is bound and the grip portion 7 of the carrier are as shown in FIG. Since they are separated from each other, the stable posture of the golf club is generally horizontal due to the principle of the pendulum. In other postures, as shown in FIG. 3, the total weight MG9 (thick arrow) of the bound golf club is separated from the grip portion 7 by 10 L. Therefore, in the posture of FIG. A moment (rotating arrow) will be generated, and holding it in this posture is a heavy burden. In addition, as shown in Fig. 4, since the human hand is in a direction slightly lowered by θ degrees in the forward direction in the natural state, holding the bound golf club in a horizontal state imposes an extra burden on the wrist, and the player goes to play. It becomes a hindrance to.

The number of golf clubs left behind on the golf course is increasing year by year, but at present, there are many cases where lost players are returning due to discoveries and notifications by latecomer playgroups. However, a player who misplaces a golf club is a factor that unnecessarily prolongs the round time in order to use a substitute golf club or to return to the search. In addition, for golf course managers, the labor of taking over lost and found items, storage and management, etc. will increase, resulting in a management loss that is not limited to the loss of personal property. .. Many of the above-mentioned second bags are designed to be carried by hooking them on a caddy bag because they cannot be loaded by existing golf carts. However, as the number of accidents involving other objects increases, the caddy bag is used. An increasing number of golf courses are requesting to refrain from using sub-bags.
In terms of golf course management, misplacement of golf clubs by players has become a problem.

On January 1, 2019, the British Golf Association (R & A) and the United States Golf Association (USGA) revised the rules. One of the purposes of this amendment is to correct that it takes too much time to play, for example, the ball investigation time was shortened from 5 minutes to 3 minutes, and one stroke does not take more than 40 seconds. Etc., and 9 holes were set within 2 hours and 15 minutes. Misplacement of a golf club on a golf course by an elderly player is a factor of time loss that goes against this revision of the time reduction rule, and the effect on non-elderly players cannot be ignored.

Meng Kurinobu et al., Tokyo Metropolitan Institute of Health and Longevity Medical Center, etc. Grip strength data, Japan Sports Agency physical fitness survey data among "Age-specific test results, grip strength, upper body raising, long sitting vs. forward bending"

The above issues are summarized.
The number of self-players who do not have a caddy in golf course play is increasing. The breakdown is that about half of golf players are elderly people aged 60 and over, and an increase in forgetfulness due to aging causes misplacement of golf equipment, and countermeasures are required.
・ Several golf clubs are carried by hand to capture the green, but there are many cases where they are bundled by hand and carried, and a simple carrying tool is required.
・ As the number of forgetting to collect golf clubs placed around the green is increasing, there is a need for a means to prevent forgetting to collect golf clubs.
-When a golf club is laid directly on the grass, there is a need for a means to prevent the grip from getting wet due to morning dew.
-Since it is difficult to put a sub-bag that stores and transports several golf clubs on an existing golf cart, an alternative method that is not bulky is required.
・ It is etiquette to discover and deliver misplaced items, but as the frequency increases, it becomes a burden, so measures that can prevent the increase in misplaced items are required.
・ Since the burden of handling and storage management of misplaced golf clubs is increasing in golf course management, measures to prevent misplacement that are useful for golf course management are required.

The present invention is a carrier that is not bulky, can hold several golf clubs in a shape that is easy to hold in the hand, and can prevent forgetting by making the golf clubs stand on their own on the golf course and make them stand out. In addition, the grip portion of the golf club can be protected from wet grass.
Furthermore, because it is small and lightweight, it is not bulky even if a large number of golf clubs are stored, so golf club carriers that can be rented out to self-players by golf courses and can be used as equipment to reduce misplacement of golf clubs in golf courses. The purpose is to provide.

A hand-held transport tool for golf clubs consisting of a substantially cylindrical holding portion that fits and binds a shaft portion near the head of the golf club in order to make it easier to hold several golf clubs when carrying around. The holding portion is a grip portion. The length of the holding portion is almost the same as or longer than that of an adult fist, and the cylindrical side surface of the holding portion has a groove for easily attaching and detaching the shaft portion of the golf club. In a holding portion provided on the substantially cylindrical side surface parallel to the central axis of the cylinder and in which the heads of the plurality of golf clubs are aligned and held at one end of the cylindrical shape, the cylindrical bottom surface of the holding portion is held. An anchor pin that extends along the extension line of the central axis of the cylindrical holding portion is attached to one end, and by pushing the anchor pin into the ground, the head side of the golf club is held downward and becomes independent on the golf course. It is characterized by being able to make it.

The substantially cylindrical holding portion has a configuration in which the tip portion and the rear end portion are divided into at least two parts with respect to the axial direction of the cylinder, and the tip portion and the rear end portion are integrally formed by means for fastening the tip portion and the rear end portion in the axial direction. It is characterized by being converted.

The holding portion is made of a flexible material, and the width of the opening by the side of the entrance of the groove or the wall of the groove constituting each of the plurality of grooves is slightly narrower than the shaft diameter near the head of the golf club. The flexible material is formed with the width of the golf club, and the golf club is held by a drag force inserted by the shaft portion of the golf club by expanding the opening.

The substantially cylindrical holding portion has a configuration in which the front end member and the rear end member are divided into at least two in the axial direction of the cylinder, and the means for fastening the front end member and the rear end member in the axial direction is provided. In a device in which the rear end portion of the anchor pin extends and penetrates the holding portion to form a part of the fastening means, a hole through which the hook or the like is passed is provided at the end portion through which the anchor pin penetrates the holding portion. It is characterized in that it also serves as the protrusion.

In the present invention, a plurality of golf clubs are held by using a holder, and the holder is made to have a substantially cylindrical shape so as to function as a grip portion. The holder holds the shaft near the head of the golf club, but since this portion is generally near the center of gravity of the golf club, the holder has the center of gravity of the golf club bound by holding the holder of the present invention by hand. You can do things. Therefore, the golf club can be easily transported because no excessive force is applied to the wrist regardless of the posture of the bound golf club.

Further, since the anchor pin is extended and mounted along the cylindrical shaft extension direction of the holder portion and the anchor pin is pushed into the ground of the golf course, the holding portion holding the golf club can be made independent. There is no need to worry about getting the grip of the golf club wet even if the grass is wet. Further, since the bound golf club is independent on the ground, the visibility is improved, and the effect of preventing forgetting to collect the golf club after the cup-in is great.

(First Embodiment)
A first embodiment of the golf club carrier according to the invention will be described with reference to FIGS. 5 to 10.
FIG. 5 is an external view of the golf club carrier of the present invention, FIG. 6 is an explanatory view of the relationship between the size of the hand and the size of the grip portion, and FIG. 7 shows the golf club carrier of the present invention in a plastic bag. FIG. 8 is an example diagram in which the iron is held in the golf club carrier, FIG. 9 is an example diagram in which the golf club carrier is carried by a caddy bag, and FIG. 10 is a diagram in which the golf club carrier is carried on the ground. It is an example figure which made it self-supporting and protected the grip with a plastic bag.

As shown in FIG. 5, the golf club carrier 11 of the first embodiment has a substantially cylindrical holding portion 12 and a groove 13 on the cylindrical side surface of the holding portion 12 parallel to the central axis of the cylinder. Is provided. In the first embodiment, three grooves 13 are provided at equal intervals. The shafts 2 in the vicinity of the heads 1 of the several golf clubs are fitted and held in the grooves 13 to bind the several golf clubs. Further, the holding portion 12 also serves as a grip portion when transporting a plurality of bound golf clubs, and the length of the holding portion 12 provides a dimension for ensuring the holding of the golf club and being easy to grip by hand. It is the length.

On top of that, an anchor pin 14 extending along the extension line of the central axis of the cylinder is attached to one end surface of the holding portion 12 corresponding to the cylindrical bottom surface. The anchor pin 14 is selected to have a thickness and an extension length that are easy to push into the ground of a golf course and have strength that allows the anchor pin 14 to stand on its own while holding a plurality of golf clubs. In the experiment of the inventor, when an iron-based material is used, a thickness of about 6 mm and an extension / extension of about 200 mm are suitable.

Further, a protrusion 15 is provided at the other end of the holding portion 12 to which the anchor pin is mounted. The protrusion 15 is provided with a hole 16. The hook 19 can be prepared as one of the accessories for making the use of the golf club carrier of the present invention convenient. A string 17 is connected to the hook 19, and a carabiner 18 is connected to the other end of the string 17. The carabiner 18 is generally a metal fitting having a movable gate, and the hook 19 can be detachably connected by passing the carabiner 18 through the hole 16 provided in the protrusion 15.

6A and 6B are explanatory views of the relationship between the size of the hand and the size of the grip portion, FIG. 6A is a view of the extended hand from the back of the hand, and FIG. 6B is a state in which the grip bar is gripped by the hand. A side view, (c) is a front view of a state in which a grip bar is gripped by a hand, (d) is an example view of a crown type of a holding portion, and (e) is an example view of an inverted crown type of a holding portion.
FIG. 6A is a view of the extended hand viewed from the back of the hand, and the length of the arrow drawn on the back of the hand is a dimension called “hand breadth”, according to Non-Patent Document 3. For example, the average value for Japanese adult men is 83.3 mm and the average value is 89.5 mm for the 95th percentile, and the average value for adult women is 74.0 mm and the average value is 78.4 mm for the 95th percentile.
According to Non-Patent Document 4, it can be seen that the maximum average value of foreigners' hands is 110% for men and 107% for women when based on Japanese.
FIG. 6B is a view when the grip bar is gripped, and according to the experiment of the present inventor, it was found that the width of the hand is about 105% larger than the width of the hand when the hand is reached.
Further, in actual golf play, it is rare to perform with bare hands, and considering wearing gloves, the size of the width of the hand is about 105% of the size of the extended hand in the state of bare hands.
FIG. 6D is a side view of the holding portion 12, which is an example of a crown shape in which the central portion in the longitudinal direction has a diameter larger than that of both end portions.
FIG. 6E is a side view of the holding portion 12, which is an example of a shape called an inverted crown type or a drum shape in which both ends in the longitudinal direction have a diameter larger than that of the center.

The longitudinal dimension of the holding portion 12 is determined based on the size of a human hand, which is easy for many users to grasp. The length of the holding portion 12 may be slightly narrower or longer than the width of the hand while being held by a human hand. For example, when the crown type shown in FIG. 6 (d) is adopted with a length of 89.5 mm of the 95th percentile of a Japanese man for men, according to Non-Patent Document 3, the hand of a small Japanese man is used. Since the width is 76.5 mm (2.5th percentile), when the increase due to grip and the increase due to wearing gloves are taken into consideration, it becomes 76.5 x 1.05 x 1.05 = 84.34 mm, which is 89. The length of .5 mm slightly protrudes from the hand. On the other hand, in the case of a foreigner with a big hand, the same calculation shows that it is 110% of the average value of Japanese men.
83.3 × 1,1 × 1.05 × 1.05 = 98,14 mm, and the length of the holder 12 is slightly shorter than the hand width.

On the other hand, if the shape of the holding portion 12 is an inverted crown shape as shown in FIG. 6 (e), the end portion serves as a flange, so that it is a little difficult to hold if the length of the holding portion 12 is shorter than the hand width. Therefore, it is good to prepare several lengths.
FIG. 6C is a front view of a state in which the grip bar is gripped by hand. According to Non-Patent Document 5, the thickness that is easy to grip is in the range of 30 mm to 40 mm in diameter for Japanese adults, and the thickness that makes it difficult to grip if it is thicker than this tends to be thinner in the elderly than in the young. There is a report that there is, and it is understood that the diameter should be selected according to this report.
Since the length and diameter of the holding portion 12 are also used as the portion that grips this portion, it is easy for many people to use it by determining one or several types based on the above data.

FIG. 7 is an example diagram in which the golf club carrier is stored in the plastic bag 22, and the vinyl bag 22 can be mentioned as one of the auxiliary tools for making the use of the golf club carrier of the present invention convenient. The plastic bag 22 is large enough to accommodate the golf club carrier 11 of the present invention, and it is even better if there is a fastener that can open and close the entrance of the bag. As shown in FIG. 7, it is desirable that the golf club carrier 11 and the hook 19, the string 17, and the carabiner 18 that make the use of the carrier convenient can be stored and placed together.

FIG. 8 is an example view in which the holding portion 12 of the golf club carrier 11 holds the shaft 2 of the golf club. As shown in FIG. 8, each head 1 of the golf club is held so as to be aligned with the anchor pin 14 side of the holding portion 12. In this state, the holding portion 12 functions as a grip portion for carrying the three bound golf clubs, and the anchor pin 14 is pushed into the ground of the golf course, so that the entire holding portion 12 can stand on its own. It shows the feasibility of achieving both transportation and independence with the minimum number of members.

FIG. 9 is an example of a state in which a golf club bound by a golf club carrier 11 is put in a caddy bag. The portion exposed from the caddy bag is drawn with a solid line, and the portion exposed from the caddy bag is drawn with a broken line inside the caddy bag. For other golf clubs that are not tied, the exposed part is marked with a chain double-dashed line. As shown in FIG. 9, since the golf club bound by the golf club carrier 11 is not bulky, it can be used without increasing the load other than the caddy bag.

Next, FIG. 23 shows the results of investigating the volumes of the standard caddy bag and the second bag, the volume of the golf club carrier of the present invention, and the occupied floor area. The caddy bag and the second bag will be hooded, and the inside dimensions of the box in which they can be contained will be compared. The unit of length is cm, the volume is converted to liters, and the floor area is square centimeters. The order of dimensions is width x depth x height. In terms of volume ratio, caddy bag: second bag: present invention = 323.9: 45.4: 1 occupied floor area ratio was caddy bag: second bag: present invention = 73: 10.5: 1.

(Effect of the first embodiment)
1) As shown in FIG. 8, three irons can be bundled compactly.
2) The holding portion 12 is made in a size that is easy to hold in the hand, and there is no inconvenience such as being difficult to hold because this portion also serves as a grip portion.
3) Since the vicinity of the head 1 of the golf shaft 2 is bound by the holding portion 12, the holding portion is approximately the center of gravity in the bound state, and the rotational moment is generated by the holding portion 12 regardless of the posture of the three bound golf clubs. Since it does not hang on the grip part, it does not apply excessive force to the wrist holding the grip part.
4) The length of the holding portion 12 is such that the shaft 2 of the golf club can be held and held without being separated even when the shaft 2 of the golf club is held and bundled, and there is no risk that the golf club will be separated and pinch fingers or gloves.
5) When moving with a passenger golf cart or the like, since the single unit of the present invention is compact, the golf club can be carried in a bound state in a caddy bag.
6) Three irons necessary for capturing the green are selected and headed for the green. As illustrated in FIG. 10, in the golf club carrier 11 of the present invention, the anchor pin 14 is held in a state where the golf club is bound. By pushing it against the ground, it can stand on its own and improve visibility, which helps prevent misplacement.
7) Further, in FIG. 10, since the golf club can be made to stand on its own in a bound state, by covering the grip 3 of the golf club with the attached plastic bag 22, the play can be continued without getting the grip 3 wet even in the case of unexpected rainfall.
8) As shown in FIGS. 7 and 23, the golf club carrier of the present invention is not bulky and compact, so that it is easy to store a large number of golf club carriers. Therefore, it is easy to build a mechanism that can reduce the management man-hours due to misplacement by lending the golf course to the self-player to prevent misplacement.

(Third Embodiment)
In the cage 12 of the present invention, the occasional holding force for holding the golf shaft 2 in the groove 13 provided in the cage 12 is such that the width of the groove 13 is slightly narrower than that of the shaft 2. , The repulsive force corresponds to the shaft 2 when the groove 13 is expanded. The dimensional relationship between the width of the groove 13 and the diameter of the shaft 2 is closely related to the pushing force of the shaft 2 and the holding force of the holder 12 holding the shaft 2. I will explain.

In particular, the groove 13 of the holder 12 has a high holding force of the shaft 2, and it is required that the golf player wants to attach and detach the shaft 2 to and from the holder 12 with a light force. Therefore, the groove 13 having a simple structure is required to be devised to satisfy conflicting requirements.

FIG. 15 is a diagram illustrating a cross-sectional shape that can be said to be the basic shape of the groove 13 in which the shaft 2 of the golf club is fitted in the holder 12 that constitutes the golf club carrier 11 of the present invention. Is an example of an uninflected word with respect to the center of the groove. In FIG. 15A, the holding portion 12 is made of a flexible material such as rubber, and the distance between the pair of side walls facing each other of the groove 13 is formed to be slightly narrower than the diameter of the shaft 2. In the example shown in FIG. 15B, the width of the opening of the groove 13 similarly formed of rubber or the like is overhanged so as to be narrower than the distance between the opposite side walls at the back of the groove 13. It is explanatory drawing. FIG. 15C is an example of a groove 13 in which the holding portion 12 is formed by using a synthetic resin material or the like which is a material rich in elasticity, and the width of the opening of the groove 13 is as in the example of FIG. 15B. This is an example in which a dimension narrower than the depth of the groove 13 is given, and the synthetic resin material surrounding the groove 13 is shaped like a leaf spring so as to be easily elastically deformed.

FIG. 16 is a dimensional view of a test piece performed to specify a shape for effectively holding the shaft 2 of the golf club according to the shape of the groove 13, and FIG. 24 shows the experimental results. is there.
FIG. 16A shows a groove shape in which the symmetrical groove 13 shown in FIG. 15B of the previous figure is replaced for a single experiment, the opening width is 7.2 mm, and the diameter at the back of the groove is 9. It shows the diameter of 0.0 mm and the alternative round bar of the shaft used as an alternative to the shaft 2 of the golf club. A chrome-plated steel material having a diameter of 11.0 mm is used as a substitute round bar for the shaft with respect to this groove. In FIG. 16B, the cross section of the groove 13 is asymmetric with respect to the center of the groove, the opening is a cross section shifted by 0.3 mm while maintaining the opening width of 7.2 mm, and the amount of overhang is 0. The cutout was 0.3 mm on the opposite side, which was increased by 3 mm. In FIG. 16 (c), the overhang is increased by 2.0 mm with respect to (a) while the opening width remains 7.2 mm, and the cutout amount on the opposite side is set to 2.3 mm.
In the experiment, rubber was used as a flexible material for forming the holding portion 12. A groove 13 having the dimensions shown in FIG. 16 was provided in a rubber block having a thickness of 20 mm, and an alternative round bar was pushed in as a substitute for the shaft 2 of the golf club using a push-pull gauge to measure the load. In this experiment, the holding force of the shaft 2 is measured by the load when pulling out the alternative round bar of the shaft by the principle of leverage, and the torque required when pushing the round bar while turning it as a measure to reduce the pushing force of the round bar. And the pressing force was measured. A part of the experimental result is shown in FIG. 24.

In FIG. 17, as shown in the experimental results of FIG. 24, in order to explore the principle that the pushing force can be reduced by rotating the shaft, the rubber block used in the experiment is provided with a grid having a pitch of 1.5 mm. , It is a photograph which observed the deformation of the lattice. FIG. 17 (a) is a photograph of only the groove, FIG. 17 (b) is a photograph of pushing the shaft into the groove without rotating it, and FIG. 17 (c) is a photograph of pushing the shaft while rotating it counterclockwise. d) is a photograph of pushing the shaft while rotating it clockwise. FIG. 18 is an explanatory view of the name of the asymmetric groove, and to explain in light of the photograph of FIG. 17, in FIG. 17 (d), the overhang portion is dragged by the shaft and deformed due to the clockwise rotation of the shaft. On the other hand, the cutout portion is less deformed. It was observed that the shaft was slid and pushed into the cutout part with the overhang part as the fulcrum.

According to Non-Patent Document 6, the average value of the grip strength of the group in which the elderly have difficulty opening the PET bottle cap and the group in which the PET bottle cap is easily opened can be read from the graph.
Average grip strength of difficult group: 27 kg
Easy army average grip strength: 29 kg
Therefore, it is considered that the decrease in muscle strength is not the main cause of difficulty in opening the cap. Something like a knack seems to be related.
As shown in the experimental results of FIG. 24, it has been found that when the shaft 2 is held in the groove 13, the required pushing force becomes smaller when the shaft 2 is pushed while rotating than when it is simply pushed. The holding force of the shaft 2 is high, and it is a contradictory requirement that the player can attach and detach the shaft 2 to and from the holder 12 with a light force. By disseminating it as a knack, conflicting demands can be met.

According to Non-Patent Document 7, the average grip strength of Japanese is 43.17 kg for boys aged 60 to 64, 26.56 kg for girls, 38.06 kg for boys aged 70 to 74, and 38.06 kg for girls. The average is 23.86 kg. Considering that the average value of the PET bottle cap easy-to-open group is 29 kg, the elderly female group measured by the Japan Sports Agency is lower than the average of the difficult-to-open group, and the shaft of the golf club of the present invention. The lower limit of the pushing force required for attaching / detaching 2 to / from the holder 12 should be carefully set.
However, since there is a knack for making it difficult to open the PET bottle cap, it is possible to reduce the pressing force required by rotating the shaft 2 when attaching and detaching the shaft 2 of the present invention to and from the holding portion 12, and the groove is formed. It is possible to make the cross section of 13 asymmetrical and to display (not shown) a mark indicating the rotation direction of the shaft 2 on the surface of the holding portion 12.

FIG. 18 is an explanatory view of the name of the asymmetric groove, and to explain in light of the photograph of FIG. 17, in FIG. 17 (d), the overhang portion is dragged by the shaft and deformed due to the clockwise rotation of the shaft. On the other hand, the cutout portion is less deformed. It was observed that the shaft was slid and pushed into the cutout part with the overhang part as the fulcrum.

FIG. 19 is a perspective view of a working state in which a golf club is set on the holding portion 12 of the golf club carrier of the present invention. When the head 1 is grasped by hand and the rotational force is transmitted to the shaft 2 as shown in the figure, the head Since the radius of gyration of 1 is large, the rotational force applied to the hand is small due to the principle of the wheel set. If the target value of the pressing force of the shaft substitute round bar in the experiment or the target value of the product is determined, it can be determined by a method of obtaining the width dimension of the groove 13 with respect to the diameter of the shaft 2. The cross-sectional shape of the groove 13 of the actual cage 12 may be determined from an alternative experiment in consideration of the combination with the hardness of the rubber material, the roughness of the surface, and the like.

(Effect of the third embodiment)
