Problems to be solved by the invention

  When an elderly person walks using a cane, it is necessary to lift the cane and push it forward, consuming considerable energy each time, placing a burden on the wrist etc., and continuing to use for a long time, Excessive fatigue on wrists. Further, since the wrist is not supported, the wrist may be twisted during use. In a cane called a medical Lofstrand clutch as shown in FIG. 8, since the upper arm is fixed, there is a problem that when it falls down, it does not move away from the arm and there is a risk of fracture or the like. Also, in order to climb the stairs, it is necessary to lift the cane, which requires a large amount of energy, and the conventional cane operates from the shape of the cane while looking at the position where the cane is pushed. There is a problem that it will bend forward.

  The present invention solves such a conventional problem, and an elderly person can operate with relatively little energy, can smoothly walk and raise and lower stairs, and is less fatigued even if used for a long time. An object of the present invention is to provide a high-function cane that is good for health because it has little risk of twisting the wrist and can walk while stretching its back when in use. It should be noted that the present invention is not limited to the elderly, and is intended to be used for non-healthy persons, for example, those who were naturally born with a disability in their feet, or those who have temporarily lost their foot function due to injury, etc. Yes.

  The present invention relates to a cane comprising a support column 4, a stone thrust 5 formed at the lower part of the support column 4, a grip base 1 formed at the upper part of the support column 4, and a grip 2 attached to the grip base 1. A wrist provided with a grip 2 that is inclined downward in the forward direction from the grip base 1, and a wrist contact surface that is formed in a concave shape on the upper end of the support column 4 so as to hit the wrist in a natural manner when used. A pad 3 is provided, and the weight of the stone bump 5 is set to a high weight so that it can move stably like a pendulum during walking.

(3) The metal fitting 6 is insert-molded into the stone butt 5 and assembled to the pillar 4. (4) The cross-sectional shape of the stone butt 5 is the same as that of the pillar 4 on the joint surface of the pillar 4. (5) Grip base 1 and support column 4 are formed so that the area and volume increase smoothly toward the ground contact surface. (7) A part of the ground contact surface of the stone bump 5 is made of a hard rubber formed in an R shape. (8) The stone bump 5 is formed of a tire material for automobiles. A material that is lighter than the material of 4 To, is to attached inclined at (10) an angle of less than 45 ° 0 ° or more before downward grip 2 is in the grip base 1.

The invention's effect

  According to the highly functional cane of the present invention, even elderly people with weak physical strength and muscle strength can operate the cane with less energy using the moment of inertia, can walk smoothly, and continue to use for a long time. There is less fatigue, less risk of twisting the wrist, etc. It is possible to walk with the back straight and to climb the stairs smoothly. Also, even elderly people with weak muscles can hold the cane firmly, and the cane can be easily moved forward with little effort. It can be used as the best form suitable for the physique of the user, the skeleton, and the bending of the wrist joint, such as selecting materials that will not break and cause injury. The cane of the present invention is not limited to elderly people, and may be used for non-healthy people, for example, those who are naturally born with a disability in their feet, or those who have temporarily lost their foot function due to injury, etc. Have the same effect.

  It is preferable that the wrist rest 3 is attached to the upper end portion of the support column 4 so that the angle can be adjusted as in claim 2. In addition to the above effects, the personal physique and skeleton can be obtained without twisting the wrist. The effect is that you can hold the cane in the best shape according to your needs.

  According to the third aspect, by forming the stone bump 5 with a hard rubber material, in addition to the above effects, there is an effect that it is excellent in wear resistance and can be used stably for a long period of time.

  In addition to the above-described effects, there is an effect that a strong and stable cane can be obtained in addition to the above effects by insert-molding the metal fittings 6 on the stone bumps 5 and assembling them to the support posts 4.

  As in claim 5, it is preferable that the cross-sectional shape of the stone bump 5 is the same as that of the support column 4 on the joint surface of the support column 4, and that the area and volume increase smoothly toward the ground contact surface. In addition to the above-described effects, there is an effect that a larger moment of inertia can be obtained.

  In addition to the above-described effect, the cross-section of the support rod 4 has an ellipse or a shape obtained by cutting a part of the cross-section. .

By using the grip base 1 and the support column 4 as a magnesium material as in claim 7, in addition to the above effects, there is an effect that a lightweight and high strength cane can be made.
In addition to the above effects, by reducing the amount of pieces and obtaining a smooth movement of the cane, in addition to the above effects, a part of the ground contact surface of the stone thruster 5 is formed in an R shape. There is an effect that is.

  According to the ninth aspect, by forming the stone bump 5 with the tire material for automobiles, in addition to the above-described effects, there is an effect that it is possible to make an even lighter and higher strength cane.

  As in claim 10, it is preferable that the material of the support column 4 is a lighter material than the material of the stone bump 5, and in addition to the above effect, the weight of the entire cane can be reduced. There is an effect that can be done.

  As in claim 11, it is preferable that the grip 2 is attached to the grip base 1 at an angle of 0 ° or more and 45 ° or less downward in the front direction. The climbing can be smoothly performed with relatively little energy.

  In addition to this, the tip of the cane is naturally swung forward by the fulcrum and angle of the weight balance provided by the grip 2 provided in front of the base, and in addition to the overall configuration of the present invention, it projects forward like a conventional cane. There is an extraordinary effect of walking in a good posture without worrying about the tip of the cane.

The present invention will be described in further detail.
As a result of analyzing the state in which the cane is actually used and experimentally producing and examining canes having various structures and shapes, the inventor has found that the grip 2 is inclined forward from the grip base 1 of the support column 4 as shown in FIG. The wrist rest 3 is provided with a wrist rest surface formed in a concave shape so as to hit the wrist in a natural manner at the time of use. It has been clarified that the cane can be operated with less energy by generating a moment of inertia by increasing the weight of the. The weight of the stone bump 5 needs to be set to such a weight as to make a stable movement like a pendulum during walking. In addition, the stairs can be smoothly climbed by providing the grip 2 so as to be inclined downward in the front direction from the grip base 1. The present invention, combined with the constituent elements described in claim 1, achieves an extraordinary effect that the walking can be stably performed with a low energy and a posture in which the back is stretched.

  Further, by attaching the wrist rest 3 formed in a concave shape to the upper end portion of the support column 4, it becomes possible to provide a cane most suitable for the individual physique and skeleton. The ideal length of a cane is half the height of the person using it plus a few centimeters. Conventional canes are generally used by elderly people simply by cutting down the lower part of the ready-made cane and covering it with stone bumps. I can not say. In particular, the angle of the grip portion has already been determined, and there are individual differences such as the degree of bending of the wrist joint, and in most cases the optimum angle cannot be secured. Keeping the grip at the wrong angle will hurt your wrist joint.

  There are few problems with the length of the cane, but there are T-shaped, L-shaped, and U-shaped types of grips, and the conditions for gripping are slightly different. At present, the wrist joint angle is not taken into consideration. The cane is the same as the glasses, and the angle and shape according to the individual's physique and the degree of bending of the joint are important elements. If a cane that does not fit the person is used, the wrist joint may be damaged. However, in the stage of manufacturing a new cane, the manufacturing cost is given priority. For example, most of the pillars are purchased there, and grips and stone butt are purchased from each manufacturer. Because of this way of making, just as things called digital home appliances can be made by gathering parts, the cane also expresses the philosophy and philosophy of the creator as a whole. As a result, it is one of the reasons why only products with no big difference appear in any cane maker.

  Even if an elderly person intends to lift the cane by himself, the elderly person does not actually lift up as expected, and often hits the lower part of the cane where there is a step such as a staircase and becomes full of wounds. In addition, there are many elderly people who are using slippery and dangerous conditions despite the time to replace the stone bumps. There is also an elderly person who holds the grip part in the opposite way to the original way of gripping the cane, which in principle is a way of gripping that clearly damages the wrist joint. For the sake of wrist bending, the angle is actually easy to grip.

  FIG. 7 shows the structure and form of a typical cane that is commercially available, but basically comprises three parts. In other words, grips, struts, and stone thrusters, and the angle of the grips is fixed with the struts upright, so depending on the person using them, the wrist joints are twisted and bent at an unreasonable angle. There was a fault that would hurt. The pillar is made of wood, carbon, aluminum, etc., but there has been a drawback that wood and carbon break in the past. In addition, the lower part of the support has a disadvantage that it hits and is damaged when passing through a place with a step or the like. Many aluminum prop types have a double structure, and when deciding the length of the cane, slide the outer and inner props, align the holes prepared in advance, and insert the pins there However, since the pitch of the prepared holes is an interval of about 25 mm, the optimal length for the height of the user cannot be secured. As for the stone attachment, it seems to be an extremely thin object because of design priority, but it is out of the question from the viewpoint of not slipping, and there is a risk of getting stuck in joints and causing unexpected accidents such as falls. Furthermore, although it depends on the habit of the user, it is dangerous because the replacement time is not known despite the fact that it has been remarkably reduced.

  FIG. 8 shows a cane called a medical Lofstrand clutch, which is provided with a semicircular arm rest at the top of the cane so that the grip can be gripped on the upper arm. However, since it is fixed to the upper arm, there is a disadvantage that it does not leave the arm when it falls, and there is a risk of fracture or the like. The semicircular arm rest is made of plastic and is covered with a cloth. However, there is a drawback that the portion that hits the arm becomes painful or gets muddy with sweat when used for a long time. In addition, most of this type of wand has a drawback of being heavy because it is made by processing a stainless steel round pipe.

  FIG. 9 is a diagram showing a state when a grip-type cane called a conventional L-shape is gripped. Because the angle of the grip is fixed, depending on the person who uses it, as shown in the figure, it is grasped while twisting the wrist a little. If you continue to use it for a long time in such a state, there is a risk of damaging the wrist joint. And when it falls unexpectedly or staggers, it tries to support the body at one point of the wrist joint, so there is a risk that the weight is applied to the wrist, the joint is damaged, and an accident such as a fracture occurs.

  FIG. 10 shows a conventional way of gripping a cane as a means for removing the above-mentioned drawbacks. If you lower your arm and grip your finger in a natural way without twisting your wrist, your index finger will point downward from your little finger. In other words, in the same state, for example, when holding a pencil, the angle of the index finger is lowered. Therefore, when the horizontal line is set to 0 ° with the cane vertically set, the grip 2 can be gripped without tilting the wrist by inclining the grip angle in the range of 0 ° to the lower 45 °. By providing the wrist rest 3 of the present invention in this state, the cane is held at two places, the grip 2 and the wrist rest 3, so that stable walking and the burden on the wrist can be reduced. FIG. 11 is a view showing a posture when a conventional cane is used.

  Also, when observing the cane used by elderly people, you can often see the bottom of the cane being full of scratches. This is the result of an elderly person hitting a corner or the like when he passed through a stepped area such as a staircase, even though he intended to lift it up enough. There are also some problems with stone thrust. There are two main meanings of a stone thruster. One is a slip stopper to prevent accidents such as falling when the staff sticks, and the second is to reduce the impact when the staff is thrust. This is to ease the impact on the wrists, elbows and shoulders. If you look at the cane that is actually used with that in mind, it depends on the habit of the person who uses it. It is slippery and very dangerous, but one reason is that the standard for replacement is not clear. There is also a cane with a very thin stone, either because of the emphasis on design, but there is a danger of falling into a gap such as a tile joint or drainage lid, etc.

  FIG. 13 is a diagram in which the wrist rest 3 is assembled so that the grip 2 can be gripped in a natural manner without twisting the wrist, and the wrist bend can be flexed differently depending on the physique and skeleton of the user.

  FIG. 14 shows that as a means for making it easier for an elderly person to put out the cane with a little effort, the above-mentioned moment of inertia is more easily applied from the moment the grip 2 is placed in front of the column and lifted. The weight of the protrusion 5 is set so as to be high enough to provide stable movement during walking.

  FIG. 15 is a view showing a state when the above-described embodiment is taken and the cane of the present invention is lifted.

  FIG. 16 shows the relationship between, for example, a staircase and a cane at a step where the above-described problem exists. As a means for reducing damage by hitting, the stone bump 5 is raised by one step of the staircase. That is 20 centimeters.

  FIG. 17 is a cross-sectional view of the stoned 5 so that the replacement time of the worn stoned 5 can be visually determined.

  FIG. 18 shows the shape and movement of the cane according to the present invention, in which the side of the stone thruster 5 is eliminated and a smooth walk is obtained.

  Hereinafter, the configuration of the cane of the present invention will be described in detail according to the drawings. FIG. 1 is an assembled side view of the cane of the present invention. The support 4 includes a strut 4, a stone thrust 5 formed at the bottom of the support 4, a grip base 1 formed at the top of the support 4, and a grip 2 attached to the grip base 1, and the grip 2 moves forward from the grip base 1. The wrist rest 3 is provided with an inclining downward, and a wrist rest 3 having a wrist resting surface formed in a concave shape so as to hit the wrist in a natural manner at the time of use. The weight of the stone bump 5 is set to such a high level that it can move stably like a pendulum during walking.

  FIG. 19 is a perspective view of the cane of the present invention. The stone bump 5 has a shape that makes the lower part of the grounding surface thicker in order to obtain a larger moment of inertia that is generated by making it heavy enough to achieve stable movement, and is made less slippery by expanding the grounding area. As such, it is preferable to use a rubber material of an automobile tire having a high friction coefficient and excellent wear resistance.

  It is desirable to use a push-out material of magnesium that has the lightest specific gravity among metals and has sufficient strength even if it is thin so that the user will not be injured or the like due to bending or bending. At this time, the cross-sectional shape of the support column 4 is a shape obtained by shaving an ellipse or a part thereof while the cross-section of many conventional walking sticks is a perfect circle. This makes it possible to express the characteristics of the material of magnesium by ensuring that it is thin when viewed from the front and the side has a certain width to ensure strength. The grip base 1 is also made of the same magnesium forging as the support column 4 and the upper end of the grip base 1 is made to hit the wrist at the best angle for the user. It is desirable to fix the possible wrist rest 3 with a wrist rest fastening screw 8. Adjust the angle in several stages, use a leaf spring, or incorporate a spring-like push spring in the wrist rest 3, install a ball bearing at the tip, and make a hemispherical dent on the grip base 1 body side. Various methods can be considered, such as providing the above-mentioned bearing and dropping into the indented portion every time the wrist rest 3 moves, but the method is not questioned. In the same manner as the wrist rest 3, the grip 2 formed of elastomer, foamed urethane or the like is fixed to the grip base 1 via the grip fastening screws 7 so as to be sandwiched from the left and right. The angle of the grip 2 is important. The grounding surface is set to 0 ° in the horizontal direction with the cane upright so that the grip 2 can be gripped in a natural shape with the arm lowered directly without twisting the wrist in an unnatural shape. In this case, the angle can be set in the range of 0 ° to 45 ° downward. The wrist of a person who uses the grip 2 set at an arbitrary angle as a reference can be gripped in a natural manner without twisting, and the wrist rest 3 is always in contact with the wrist, so the wand is held at two points. . The grip base 1 and the stone butt 5 to which the grip 2 and the wrist rest 3 are assembled are assembled to the support column 4 by the assembly screws 9 and 10, respectively.

  Stable walking can be obtained by adopting such a configuration and form. 2 and 3 are a top view and a bottom view of the cane of the present invention, respectively. FIG. 4 is a front view of the cane according to the present invention. By thinning the grip base 1 and the support column 4 and thickening the lower part of the stone bump 5, the generation of the moment of inertia is promoted. It plays a role to make it easier to go forward. In addition, when an elderly person passes through a stepped portion such as a staircase, the lower part of the cane may be hit and injured, but the length of the 5 main body with a stone should be extended to one step, that is, about 20 cm. By this, the effect of preventing the strut 4 from being damaged is produced.

  FIG. 6 is a right side view of the cane of the present invention. A metal fitting 6 having strength for assembling to the column 4 is inserted at one end of the stone 5, and the stone thrust 5 is firmly fixed to a screw hole provided in the column 4 via an assembly screw 10. The grip base 1 is created by forging magnesium, and a grip 2 and a wrist rest 3 are assembled thereto via a grip retaining screw 7 and a wrist retaining screw 8, respectively. The support | pillar 4 is produced with the extrusion material of magnesium, and is cut | disconnected by arbitrary length. By using extruded material, a free shape can be obtained. The stone bump 5 is made of a hard rubber material from the viewpoint of being hard to slip and having excellent wear resistance. In addition, the grip 2, the grip base 1 including the wrist rest 3, and the stone butt 5 are assembled to the support column 4 via assembly screws 9 and 10, respectively.

  FIG. 2 is a top view of the cane of the present invention, in which the protrusions are reduced from the viewpoint of safety and in order to improve the appearance. FIG. 3 shows the bottom surface of the cane of the present invention. FIG. 4 is a front view of the cane of the present invention, and the stone bump 5 secures a ground contact area by taking a wider width than the column 4. FIG. 5 is a rear view, and assembly screws 9 and 10 are provided on the rear surface in order to improve the appearance. FIG. 6 is a right side view.

  FIG. 9 is a diagram showing a state when a conventional cane is gripped. When grasping the cane, the wrist is slightly twisted because of the angle and shape of the grip. The angle when grasping the cane is one of the most important factors, and the bending of the joints of the user varies from person to person, and it will not match if the grip of a predetermined angle is kept like a conventional cane. There is a danger that people will hurt their wrists. FIG. 10 shows a method for solving this problem. The wrist rest 3 is adjustable in angle so that the grip can be gripped in a natural manner without twisting the wrist in an unnatural manner, and the grip can be gripped in the best way for the person who uses it at that time. It is something that is held in a state with When the wand is raised in a natural shape and the level is set to 0 °, the wrist rest 3 is used on the basis of the set grip 2 with a tilt at an angle of 0 ° to 45 ° downward. By fixing it at the position where the person feels best, the grip 2 and wrist rest 3 can be securely held without twisting the wrist, and by adopting its form, it fits the individual who uses it. A personal-use cane is realized.

  FIG. 12 is a diagram showing the movement of the wand when the wand is actually used. When the wand is moved forward, a rotational movement with the shoulder or elbow as a fulcrum is generated. At that time, by applying the moment of inertia generated by making the stone thruster 5 of the present invention high in weight so as to move stably like a pendulum, the tip of the staff, ie, the tip of the stone thruster 5 from the moment when the staff is lifted. Will begin to move forward. Therefore, in order to obtain a greater moment of inertia, the grip 2 is formed in the shape of the front of the support column 4.

  FIG. 14 is a view showing a state in which the walking stick of the present invention is erected and grounded. Point B is directly below point C. FIG. 15 is a diagram showing the movement of the wand when the wand of the present invention is used. When the cane is lifted up slightly and lifted from the ground contact surface, point A serves as a fulcrum, and point C tries to move by the action of a penetrating moment while drawing an arc to point D, that is, to point D. At that time, the larger the L dimension is, the higher the specific gravity of the shaded portion is. For this reason, when viewed from the side, the shape is such that the weight is concentrated at the rear of the stone bump 5.

  FIG. 13 shows the cane of the present invention in which the wrist rest 3 is attached to the upper end of the support column 4 so that the angle can be adjusted. The cane of the present invention is based on the premise that the cane is held without twisting the wrist. Therefore, the grip 2 tilted downward is provided at the same time as the wrist rest 3 to fix the wrist joint so that it does not wobble. That alone is not enough. This is because there are individual differences in how the wrist joint bends when holding a cane, and the grip angle should not be simply fixed like a conventional cane. Therefore, in order to obtain a stable grip at the best angle for the person using the wrist, the wrist rest 3 is temporarily fixed through the wrist rest fastening screw 8 and the wrist rest 3 hits the wrist at an optimum angle for the person using the wrist rest 3 as a fulcrum. Measure the position and tighten the wrist fastening screw 8 firmly at the end. The angle of the wrist rest 3 can be adjusted in several stages, and a state in which the wrist rest 3 is in contact with the grip base 1 using a leaf spring or a push spring is created. Of course, other methods may be used. The assembling angle of the wrist rest 3 once set can be set again by loosening the retaining screw 8.

  FIG. 16 is a diagram showing the relationship between a place with a step such as stairs and a cane. Elderly people are not lifting as much as they actually think, even though they intend to lift it up sufficiently in a stepped area, so they hit the lower part of the cane and damage it. Even if the elderly should lift the cane higher, it is impossible to talk to those who have weakened muscles. .

  FIG. 17 is a view showing a cross section of the stone bump 5. The original purpose of the stone butt is a cushioning material when the cane is in contact with the ground, and it is also a non-slip material, but it is used as it is, although it has been reduced by the user's bag and the replacement time has come. There are often cases. The worn stone bumps cause the impact to be directly transmitted to the wrist and shoulder when the cane is pushed to the ground, causing the joints to hurt, and there is a risk of slipping and falling. Therefore, the cane according to the present invention is made by forming two parts of the lower part of the stone bump 5 by two-color molding, for example, black rubber on the outside and red rubber on the inner part, so that the stone bump 5 is used or reduced. When the red rubber starts to appear at the bottom of the screen, it can be visually judged that it is time to replace it. As a result, accidents such as slipping or falling can be reduced.

  In FIG. 18, when the cane comes forward, a rotational motion occurs with the elbow and shoulder as a fulcrum, and then the stone thruster 5 is grounded, but the angle of the cane at that time is inclined from the rear side of the stone thruster 5. It is a figure showing the state to poke. Since the shape of the bottom surface of the conventional stone thruster is flat, it begins to decrease from the rear side of the stone thruster after long-term use, so that it becomes a piece-removed state, making it slippery and dangerous. Therefore, the cane according to the present invention, on the average, reduces the bottom surface of the stone thruster 5 by introducing a shape with the R surface in advance at the rear part of the stone thruster 5, and a smooth movement of the cane can be obtained. is there.

  FIG. 19 is a perspective view showing the configuration of the highly functional cane of the present invention. The grip base 1 is made of magnesium forging as a light and strong material for elderly people with weak physical strength, muscle strength, and grip strength. For the same reason, the support 4 is also made of extruded magnesium. Yes. In addition, you may manufacture with titanium, aluminum alloy, carbon, various synthetic resins, and those composite materials. In order to make a cane that matches the height of the user, the support column 4 is cut into an arbitrary size and adjusted to the correct size. The grip 2 may be a rubber material or urethane foam in consideration of the feel when grasped, but is not limited thereto. Two or three molding colors can be prepared to reflect the user's preference.

  The wrist rest 3 has a concave cross-sectional shape so that it can touch the wrist in a natural manner and can be held in a stable state without swinging from side to side, and the shape when viewed from above is the grip base. The side to be assembled into 1 makes a “relief” so that it can correspond to the thickness of the wrist of the user by narrowing the width, while the other end is widened and deepened so that stable holding can be achieved. ing. A screw hole for incorporation into the grip base 1 is provided on the front side, and is firmly fixed with a wrist resting screw 8. The material is preferably an elastomer, urethane foam or the like as in the grip 2, but the material is not particularly limited.

  FIG. 20 is an exploded perspective view showing the component structure of the cane of the present invention. A high-strength metal fitting 6 formed by insert molding is provided at one end of the stone butt 5 and is firmly fixed by an assembly screw 10 by being inserted into the column 4. ing. The material of the stone bump 5 is preferably a material having a high friction coefficient and excellent wear resistance.

  FIG. 21 is a diagram showing the dimensions of the grip base 1, the grip 2 assembled thereto, and the wrist rest 3. A screw hole serving as a fulcrum for the movable wrist rest 3 is provided in the vicinity of the wrist joint so as to interlock with the movement of the wrist while gripping the grip 2 attached to the grip base 1. It is preferable to set the dimension of L1 within a range of about 40 to 45 mm from the rear end of the grip 2 so that the wrist rest 3 fits. Moreover, it is preferable that the dimension of L2 shall be about 80 mm so that the grip 2 can be grasped firmly. The wrist rest 3 has a dimension of about 90 to 100 mm so that the wrist joint 3 can be stably held at the two locations of the grip 2 and the wrist rest 3 without burdening the wrist joint when the grip 2 is gripped. Is preferred. In order to ensure stable holding with the grip 2 and the wrist rest 3 attached, it is preferable that the dimension of L4 is 210 to 220 mm.

  FIG. 22 is a perspective view of the wrist rest 3, which is attached to the rear end of the grip base 1 when the grip 2 is gripped, and its cross section is formed in a concave shape so as to hit the wrist periphery in a natural shape. And since the thickness of the wrist is different for each user, the width on the front side is narrow and shallow, creating a “escape” part, and conversely, the width on the rear end side is widened and deepened to make it stable. Holding is possible.

  FIG. 23 is a view showing a state when a person having a height of 180 cm and 150 cm uses the cane of the present invention. The column 4 uses a magnesium extrusion material, but its length is very important in setting the length of the person to match the height of the user and not damaging the wrist joint, and is a conventional calculation method. When calculated based on half the height of the user plus 2 to 3 centimeters, 180 ÷ 2 = 90, and 90 centimeters plus 2 to 3 centimeters and the grip position is 92 to 93 centimeters from the ground surface. Become. From there, it is 72 to 73 centimeters, which is a value obtained by subtracting 20 centimeters, for example, 20 centimeters, but in reality, the position of the grip 2 in the grip base 1 is 2 to 3 centimeters behind. The dimension is the length after subtraction, that is, about 70 cm.
