Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ski stock, which is one of the ski equipment. , Nordek) technology improvement and ski stock with higher safety probability, as a practical product at the same level as conventional products, by simplifying production technology, simplifying the production process, keeping production costs low, etc. is there.

[Prior Art] As is well known, ski poles have changed from one pole to ones with both hands, starting with bamboo such as Nanjing Bamboo and Gochiku, and then improving strength of various materials and strength and durability. We are currently seeking higher quality such as lightweight, balance, and design, but the fundamental principles, structure, and functions have not changed in the history of 100 years of skiing, nordec gliding and alpine descent. If you look at the slow video of skiing, not only beginners, but when you are in the middle-advanced, professional, etc., the impact when poking is serious,
Looking at the screen, the shoulders are pushed up greatly, and due to the snow quality, the stock's return movement is poor with slippery snow, it does not stick when the snow surface is hard, so it may break the balance or damage various parts of the human body, Considering a long period of time, it is said that the skier's forged physical strength and skill, such as accumulated fatigue and sometimes injuries due to falls, from the beginner to the highest level, and the applications relating to ski poles in each country are seen. , With upper and lower shock absorbers, published patent publication 53-128430, 52-147131, German patent 2055597, Swedish patent 132429,
As seen in U.S. Pat. No. 3,797,845, each of these is the most important strength, durability, safety, light weight, and stock.
All of the above-mentioned applications have some serious difficulties in various conditions such as balance, simplicity and performance of mechanism, small number of parts, ease of production process, low cost, etc. As you can see, it is a proof and a reality that it has not been produced or sold as a practical product until now. The above-mentioned application content and the conical reciprocating multi-stage shock absorber of the present invention are physical and mechanical elements and their movements are of different forms, and the technical purpose is also different from the purpose of merely preventing human body protection danger.

[Problems to be solved by the invention] Although the important elements and ideal image of ski stock as a practical product have been touched upon a little in the previous section, regardless of whether it is downhill skiing or skiing, there are various types of heavy exercise and various types of snow during use. It is possible to correspond to quality, that is, light weight (a), well-balanced (b), strength and durability (c), stock length adjustment makes it easy for sports equipment stores and experienced people. Things that can be done by work (d), as little impact as possible when hitting the snow surface, protection of various parts of the human body over a short period of time, reduction of fatigue (e), stock from the snow surface competing for several hundredths of a second Can return and pull out quickly (f), the degree of cutting of the shaft tip in ice burn is a little high (g), stock is often taken in heavy snow, heavy snow, etc. As much as possible (h), the repulsive force of the buffer spring works effectively as propulsive force to improve the time regardless of whether it is downhill or downhill (i). It corresponds to the downhill or downhill applications such as alpine and nordec, and the technical level. It can be manufactured (j), safety establishment for risk prevention in the event of a fall, collision, etc. is as high as possible (k), above (ab)
cd) is filled with the current stock, but (efgh
ijk) is supplemented by one's own skiing technique, and is not yet provided on the mechanism of the ski pole itself. It has not been achieved for a long time from the principle of bamboo poles. For a long time, there are 11 items from (a) to (k). The challenge is to be able to respond to a high degree, simplify the structure, minimize the number of parts and weight, make the production process and production cost to the same level as the current high-end products, and immediately provide them as practical products.

[Means for Solving the Problem] The grip portion of the ski pole The materials shown in FIGS. 1, 2, and 3 include light metals, carbon fibers, and ceramics, but the grip portion is generally formed by one-piece molding with a synthetic resin system. Is a one-piece structure having a shape that fulfills each element and function, such as a grip portion, a pipe shaft holding portion, a three-dimensional positive-moving cam, a movable portion that is a cylinder for reciprocating movement and an internal hole that serves to hold it, and a pipe is assembled. Insert the shaft head into the shaft until it stops at the upper step, align the driven node bolt pin screw holes (18) of both members, insert the rubber cushion into the hole of the top protrusion of the shaft head, and insert it into the cylinder of the same top protrusion. ， Insert in the order of short compression coil spring, insert this into the inner hole of the grip, and align the groove of the three-dimensional precision cam with the follower joint bolt pin screwing hole, and have a three-step diameter from that groove and thread it in the middle. The driven joint bolt pin is screwed in tightly from the smaller diameter pin until it stops at the larger diameter head, and the assembly is completed. In addition to the one-body structure of the above-mentioned palm grip part, two or more materials are used to further enhance the multi-stage cushioning property. A composite structure in which members are combined becomes the entire palm grip portion (1A) of FIG. 4. The grip portion has an outer grip portion and a second inner hole (5B), and a head bolt hole at the uppermost portion, which is a cushioning material (rubber material). The inner cylinder (15) incorporated in this grip has a pipe shaft holding part, a three-dimensional positive cam, and a hard material with an internal hole. The mold of the grip (1A) is used for this inner cylinder. And the cushioning material is poured and wrapped to form the two materials. Depending on the selection and combination of these materials, the palm grip part and the inner cylinder are naturally bonded, and the two parts are separated without wearing. The former is 1
The latter comes in two types, the two-stage cushion. In the latter, the inner cylinder is fixed with bolts from the head bolt hole (17) at the top of the palm grip portion, and the palm grip portion (16) is held by the palm grip portion fixing projection (16).
The two grooves of the three-dimensional positive cam are always perpendicular to the cylinder of the inner hole in the two kinds of grips of the one-body structure and the composite structure, which completely hold A), and thereby increase the multi-stage cushioning. A groove with a width that allows the diameters of the circles on both heads of the follower joint bolt pin to be movable, on both sides of diametrically opposite sides and diagonally diametrically opposite, with two elliptical vertical bisectors along the cross-section line of Fig. 2 inside When connecting with a straight line perpendicular to the center line of the hole, all the straight lines pass through the center line of the inner hole. It has the invariant property. Depending on the necessity of necessity, such as the direction of the groove in which the rubbing rotates, the length of the groove, etc., the application such as gliding and gliding, the level of technology, etc., the upper and lower positions of the groove can be determined from the pipe shaft holding part to the grip part. Relocate the pipe shaft up to the practical upper limit It is possible, therefore, except for the above-mentioned invariant properties, the three-dimensional positive cam has the property that it inevitably changes from the necessity. Due to this, the strength and quantity of various cushions for cushioning, shaft head, pipe shaft holding part, driven joint bolt pin, etc. The function, size, shape, etc. also change correspondingly. The change of each of these elements and members is absolutely within the limit of the practical range, that is, each application of gliding, gliding, technical level of user. ， It is to take out the best function and its structure as a ski stock, and to deal with each issue in the previous section.

[Operation] The lightness (a) is to reliably correspond to the 11 items from the items (a) to (k) to be solved by the invention, and the lightness (a) is shown in FIG. The stock of the present invention is more than the stock of (8, 9, 10, 11) by 4 parts, long and short compression coil springs, rubber-like cushions, driven joint bolt pins, several g each, and the shaft head and palm grip are a little. The total weight of each member is about 20 to 10g, and the lightness is not impaired. In balance (b), the excess weight is all in the grip part, so the ideal weight distribution of the stock is used to swing it forward. And the tip feels light and the balance is rather good. The strength and durability (c) depends on the structure of the gripping part such as the pipe shaft holding part, the groove of the three-dimensional positive cam and the internal hole, and the member of the shaft head and the follower bolt pin. Protection Just like the principle of a Japanese sword, the grip is a handle, the follower bolt pin is a bamboo eye nail, and the combination of the shaft head and the pipe shaft is mechanically seen in the blade. The working relationship is exactly the same. If a cam mechanism is used in combination, the follower bolt bolt pin may loosen, and the thin and weak pipe shaft may be twisted or strength, but it may stop at the large head of the follower bolt pin until it stops. When tightened, the shaft head is tightly fitted into the upper pipe shaft of a resin-based viscous material, and it also plays the role of a nut, maintaining its strength and looseness. The long and short compression coil springs do not reach the maximum compression when the inserted and fixed rubber cushion is on the ceiling of the inner hole under the maximum pressure load that cannot be compressed any more. To have,
This is adjusted by the length of the shaft head protrusion, and the head of the follower bolt pin is also the length of the groove that does not attach to the upper ceiling of the cam groove at this time. The reason for this design is that the maximum pressure load is the pipe shaft. This is to protect the long and short compression coil springs and the follower bolt bolt pins from the shaft head, the rubber cushion and the ceiling of the inner hole of the palm grip when it is hung on the tip. The strength is the same as that of ski skis,
Durability is proved. Length adjustment (d) is disassembled in the opposite process of assembly, the pipe shaft is cut into a length according to the user, and the shaft head is attached to the shaft head with a simple jig as shown in Fig. 7. Fit follower bolt bolt pin threaded hole into pipe jig and reassemble it. Distribute jig in advance to sports equipment store. When impact problem (e) is not used In this ski ski, a long compression coil spring always presses and fixes the follower bolt pin to the bottom end of the three-dimensional accuracy cam via the shaft head. When it hits the snow surface, the long spring first loosens the cushioning function. It works together with a short spring from the middle of the stroke, and the rubber cushion and three parties work together strongly to obtain three steps of cushioning. When pulling out, it first returns with a strong momentary repulsion force and the spring action opposite to the above, In the case of the grip portion according to claim 2. Buffer is overlap of one stage or two stages,
It is difficult to obtain accurate measured values of human body protection by the above-mentioned multi-step spring action, which obtains more complex and heavy-duty cushioning, but the inclination is 28 degrees and the speed is approximately 30 km / hour for advanced skiers of ordinary adult men. Approximately 2.5 G on average for the conventional product and about 1 on average for the present invention in the present invention, which was measured by attaching a shock sensor to the shoulder joint and thrusting it on a cedar plate indoors assuming a Wedern descent. As a reference, the impact on the knee joints of the marathon athlete's foot, which recorded 1.5G, was 6.5G, and when the same athlete had a bicycle, the impact was only 0.6G at 20km / h. This multi-stage buffer mechanism returns from the software to the hard as soon as it enters, and the return instantly returns from the hard to the soft, and when the poking time is long (one second or more) or weak instead of the moment, the buffering property is maintained and the intermediate Acts on the belt.
Generally speaking, the beginners are in the soft stage, the intermediate are intermediate, and the advanced are often full buffer. Although the figures in this specification are designed with standard specifications, the joints, muscles, and nerves of various parts of the human body Protection, fatigue accumulation, each skill level, etc., enough to return the stock from the snow surface as soon as you hit (f) is very difficult for advanced skiers in the Wedern and competitive skis. 10 important factors
The degree of cutting at the tip of the ice-burnt shaft (g) is the decisive help for the strong instantaneous repulsive force of the triple spring seen in the latter half of the buffering action of (e), which competes for a few seconds of 0 minutes. ), And the phenomenon (h) in which the stock is caught without hitting heavy snow or heavy snow, the reciprocating motion of the conical rotation of the pipe shaft plays a role. The left hand rotates to the left, the right hand rotates to the right, and the sliding ski of Nordek makes the reverse rotation when it strikes. This is the direction of the inclination of the cam groove described in the fluid element of the three-dimensional positive cam according to claim 3. The direction of left and right rotation when struck is determined by the setting method of the ski. As is well known, the ski downhill is rotated by turning the left hand stock on the left hand and the right hand stock on the right hand. Use the stock on the valley side In this case, the rotation of the tip of the pierced stock must rotate either right or left, and it will rotate not in the downhill side but in the ascending direction of the mountain. As a physical property, the rotation advances in the rotating direction and in the opposite direction. Resistance occurs, the tip of the stock rotates in the direction of climbing uphill, and resistance is generated in the direction of descending. With the force of punching, the hard ice burn cuts, the goodness of piercing increases, the removal of heavy snow, solid snow, etc. The good point is that when the tip of the shaft strikes and pulls out instantly, it rotates in the opposite direction, and it is the same as a hand-turning cone for woodworking, and physically reduces the resistance of the material by the reverse rotation, and the reverse rotation of the stroke makes it Although it is a little bit, the amount of water also increases and a slipping element is added to improve drainage. The reason for making the above reverse rotation with a sliding Nordeck is that the force of the buffer spring repels when thrusting so that the buffer spring repels. Power propelled Acting as (i) the return movement of the portion of after poked of said impact issues (e) in said cushioning mechanism to aid in propulsion in natural Katachichi. Of particular importance is the fact that at the beginning of the return, the strongest repulsive force is produced in the three-stage complex, so that all competitive skis, especially the Nordeck gliding where the thrust and arm forces make up a third of the propulsive force Leads to a great improvement in time,
(J) manufactured according to the application and technical level is a standard design for the downhill of the Alpen shown and described in this figure.
The reason is described in (h), but the left hand turns to the right and the right hand turns to the left, and the cam angle is small and the groove length is long.
Strengthen springs, naturally for professionals, superlatives, races, etc. even in downhill, strengthen springs, roughly, downhill sliding, standard general, advanced, children's, etc. It is preferable to set the cam angle to 0 degrees, as shown in Fig. 3 when extremely lightweight is pursued. Danger prevention (k) is when the tip of the stock sticks at the time of tipping over, collision, etc. As mentioned in the section on buffering, the cushioning effect, which initially works from soft to hard, can be said to be a little higher than that of the conventional product, as compared to the conventional product.

[Examples, effects of the invention] Two prototypes were manufactured, one for gliding and one for gliding. In order to obtain an accurate comparison with the conventional product, the same conventional product was bought for sliding down and sliding for 2 points, and 1 point was purchased. Is a pipe shaft with the tip ring removed and the tip ring still attached, the other parts are newly made, and the other one is used as it is for competitive comparison with the prototype. Figure 1 The pipe shaft manufactured as standard use has a conical rotation angle of about 50 degrees, and the buffer reciprocating length is about 20 mm.
For gliding, the rotation angle is about 30 degrees, and the buffer reciprocating length is about 30.
The spring was made strong in mm, and it was manufactured with the example of (a) to (k) in regard to the action of the preceding paragraph, and the anxiety when snow clogged in the groove of the three-dimensional positive movement cam and became hard ice. The effect of the invention will be described together. Generally, the more expensive high-priced products are lighter and more well-balanced due to the difference in materials, but it is an important factor especially for beginners and intermediates, but it is an important factor especially for advanced users. It is said that it is good to be able to swing out with a feeling of "soo" to the other side, although it does not feel too heavy at hand, it is said that it is the weight of the total weight at hand. The weight difference between the prototype and one conventional product due to the fact that more than two-thirds is concentrated and the shaft material is strong and light is about 12 g for one slide for sliding down and about 18 g for sliding. However, since the weight increase is concentrated at hand, the sense of balance is rather good. The toughness and durability are in a wide range from beginner to advanced season for about 60 days, including the stab that seems to be benign to advanced users, and about 480 hours per hour. This is a person who likes skiing. If you convert it to a normal average, you will have used it for about 6 to 8 seasons, there was no problem as the cam groove was shining smoothly due to the rubbing of the bolt pin, during that time the follower bolt pin pin reciprocated about 20,000 times. The most worrisome point that has been reached above is the pressure load and torsional strength of the base shaft mounting of the follower bolt pin on the pipe shaft, but the shaft head is tightly filled inside despite the thin pipe. , There was no problem with the conventional product pipe shaft, the final destructive test was performed, but the structure of the grip part even if the shaft middle is broken,
The function was not damaged. This is because the strength of the mechanical structure of the Japanese sword combined with the cam mechanism described in the action section and the maximum pressure load from the shaft through the shaft head to the rubber cushion and the inner hole ceiling. This is due to such structure and mechanism. Regarding the performance and effect during use, the stock operation of beginners is always slow and the timing is slow, and especially the operation of pulling out and returning from the snow surface is ambiguous, and there are many operations that drag the stock tip to the snow surface, and commonly use stock work. It is said that the skill level can be understood, and when observed by letting the beginners use it, the difference from the conventional product is that there is less shock when punching, and the pullback operation from the snow surface is strong first and quickly next. The repulsive repulsion of the weak multi-stage spring naturally pushes up the hand without dragging the snow surface, and as a result, teaches important return operations naturally and reduces the loss of balance. Most of the beginners dislike the stock operation, but the tempo of moving into action has become faster, but on the contrary, the fun of using it has been amplified. The intermediate person feels the need for stock operation, but various rotations still occur. The effect of the stock is not fully utilized in the surgical Christiania, Wedern, tail jump rotation, etc. The trial result is a good result more than the beginner, especially the important element that the operation of pushing the stock and the timing of rotation are integrated As you can see, if you are advanced or above, you can adjust the stock according to the downhill speed, slope, terrain, snow quality, etc., and adjust the stock to the situation to assist in turning.
Therefore, each joint such as wrist, elbow, shoulder, stapes, etc.
The cervical spine above the spine, the thoracic spine and its nerves are accompanied by a fairly strong impact. At that time and in the long term, the cause of injury or illness such as muscle pain, arthritis, bruise, contusion, flesh, sprain, dislocation, etc. The first impression of using this prototype is that it is less than about one-third the impact of the conventional product, and the return of return is incomparable. It shows good results with ease, and it shows high techniques such as air turn and balance maintenance by often hitting both stocks on steep slopes of uneven terrain, even when not rotating, but all of them work reliably and are more stable than conventional products. The patent publication 53-128430, etc., which was found to have a high cost, has a complicated air cushion with a spring, a cylinder, a piston, and an O-ring, although it only buffers the top and bottom, but it is 0 Since suck or vomited following air holes 3 mm, it is estimated to take about one second or more to return,
Although he said that he was able to move up and down slowly, he said, "Wedern's downhill skier, who is above the advanced level, pokes out, and immediately pokes again."
If there is an obstacle etc., it is a problem of just a few hundredths of a second such as pushing the stock of the same hand and pushing it again right away, and with the return of the slow air cushion such as the above application, it will be pushed without completely returning. Discomfort when playing,
Besides, the large number of complicated structural parts, durability, strength, weight,
It's the idea of an amateur who just wants to have a soft cushion that makes me wonder if I know what skiing is, without considering the balance. As the number of times of use becomes higher than that of advanced skiers, the stock is shocking. It changed to the evaluation that the same effect as the conventional product was obtained without feeling uncomfortable and that it felt like it was not used, and the function that can return immediately after entering the software was well received. At the same time, it turned around. It was found that the repulsive force of the triple spring obviously helps the propulsive force and leads to the improvement of time when competing for 1/100 seconds such as skiing on skis or downhill terrain. Although it was compared with the conventional product over a total of 50 km or more several times, but it was about 20,000 times, and the accumulated record of long use time clearly shows the repulsive force of the multistage buffer spring, the hard ice of the crushing Snow surface There are some complex effects such as smoothness and good removal of heavy snow, depending on the condition of the body, but the same person made a difference of about 12 seconds at 10 km in several attempts, apparently assisting propulsion It is effective and leads to improvement of time. It also reduces fatigue and comprehensive protection of human body such as wrist, elbow, shoulder joints, cervical spine of upper spine, thoracic spine, etc. If you walk 10km on the road with orthodox leather shoes and walking shoes, the result will be the same as the result. Regarding the trial effect on snow quality, first, the snow quality is weather, temperature, time,
The nature and style of this is changing every season, but
The snow quality for skis is roughly classified into dry powder snow, powder snow, normal snow, fresh snow not stepped on by skis, ice ban, heavy and heavy snow, worse snow, and other ski slopes. There are no, but it is roughly classified into sun crust, wind crust, etc. Skiers are pleased with the above three snows, skis can slide like a sudden skill, the latter 5 bad snows are difficult to slide down It requires a higher level of skill and dislikes it, and there are many risks of accidents such as falls, but in fact, 60% or more of the whole period is the latter snow except spring skis, and recently skiing except skiing Is pressed and hardened from the beginning by a caterpillar wheel in order to make the snow on the slopes last longer. As mentioned in the section of action, the conical reciprocating motion is due to bad snow like the latter, Dots are eyes Depending on the degree of cutting at the tip of the ski stock on the barn, regardless of whether you hit the left or right, the rotation of the tip of the ski is always turning toward the higher side on the mountain side, so compared to the conventional product, a cut on the hard ice snow surface, Clearly improved catching, which reduces the escape and slippage of the stock tip, and reduces the loss of balance and falls.
Also, any skier has experienced that heavy snow or heavy snow cannot be removed after hitting the stock, and the stock can be caught on the surface of the snow. 、 I understand the precautions against accidents, I wonder why it sometimes becomes difficult to pull out the tip that is less than 10 cm from the tip of the stock to the ring. It is understood that it is difficult to pull out the fixed state where the shaft is still protruding. The tip of the shaft of the present invention is stirred in the snow by the crushing rotation when poking and pulling out, and the kinetic energy of the rotation itself, As a result, the amount of water around the hole in the snow increased, and the spring effect of the return unintentionally pushed up the hand, resulting in a triple effect, and good results were obtained. In particular, heavy snow caused by, each effect of the above and considering that are concentrated at the time of ice burn, such as evil snow is larger. Since it is not possible to experience an accident in which the human body at the tip of the stock is stabbed due to a collision or a fall, I experimented with pork with a skin of about 30 kg. I was worried because the shaft was in a kneading motion, but the rotation angle was 50. ° The result is uncomfortable because it is small, around the same time, but the effect of cushioning is still apparent. If you gradually increase the strength with the same strength as the conventional product, the conventional product will be more than a certain force. The stab, the prototype only needed to pull in the skin strongly, and even more strongly the limit that an ordinary adult man could put out, the prototype also started to stab. In the end, the stab was a matter of strength and angle. ， The answer is that the risk prevention and safety establishment are much better than the conventional products. If snow clogs the groove of the three-dimensional positive cam and there is no problem with the function of performing normal movement, the problem was whether or not the temperature was 22 ° C below zero, and the groove was artificially filled with snow outdoors. I left it for about 30 minutes and tried it suddenly while the snow was still sticky, and I repeated the experiment many times, but I smashed it just a few times by the strong vertical movement of the head of the follower bolt pin against the volume of the groove There wasn't. Although the examples and their effects have been described above, the present ski equipment has made great strides in its excellent functions and performances such as skis, bindings, ski shoes, and wears, but only by designing the ski ski alone. I changed my eyes, and the basic principle has not taken a step from the bamboo stock era. I still have the luxury goods of bamboo stock of Nanjing bamboo about 35 years ago, but only the tip ring is as it is now. The lightness, balance, and usability are as good as those of today's luxury products when they are changed to small, light ones. For example, various sports shoes such as tennis, marathon, short distance, caravan, mountaineering, soccer,
There is no limit to the number of volleyball, baskets, and town shoes, and the town shoes and ordinary leather shoes make the city one.
If you walk 0 km, you can experience how buffering is important for the healthy protection of the human body. The present invention concludes that a three-dimensional positive-acting cam is provided in a small limited internal space called the palm grip portion, which has not been achieved until now, and a three-dimensional positive cam is provided to form a cam mechanism together with a follower joint bolt pin. , Giving the shaft a conical reciprocating motion, the strength and durability of the thin and weak pipe shaft is made to be about the same as the conventional product by the shaft head and the follower bolt bolt pin, and in addition, the multi-stage cushioning cushion is stably held. The structure and combination of each of these members that fully exerts its cushioning function is the feature of the present invention. A mechanism capable of exerting important elements and functions in a structure that is simple and simple but is mutually related and assists. Moreover, the number of parts, weight, production process, cost and balance are almost the same as those of the conventional products, and the technical level is improved over many items, and in the short and long term the protection fatigue of each part of the human body is improved. To reduce the product, pulled out a variety of effects, such as enhancing the safety, to transform the ski stock from the root, to change its history, it is to provide as immediate practical goods.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski stock, which is one of ski equipment, and particularly to improve adaptability to all types of snow and improve skiing, gliding, that is, alpine and nordec technology, and to improve safety probability. Regarding high ski stock.

[0002]

2. Description of the Related Art Current ski equipment has made great strides in its excellent functions and performances such as skis, bindings, ski shoes, and clothing. However, as far as the ski stock alone is changed, the basic principle has not changed since the days of the bamboo stock. I still have the high-end bamboo stock of Nanjing Bamboo about 35 years ago, but if I change the tip ring to a small and light one like now, its lightness, balance, and usability are the same. It is as good as that. For example, there are countless sports shoes such as tennis, marathon, short distance, caravan, mountaineering, soccer, volleyball, basketball, town shoes. If you walk 10km through the town with the town shoes and ordinary leather shoes, you can also experience how buffering is important for the healthy protection of the human body.

Ski poles have changed from a single pole to a two-handed pole. Beginning with bamboo such as Nanjing Bamboo and Go bamboo, after that, with the development technology of various materials, strength,
We are currently in the pursuit of higher quality such as durability, light weight, balance, and design. However, the basic principle, structure, and function have not changed in the history of ski 100 years. If you look at the slow videos of Noldeck's gliding and Alpine downhill skiing, the impact at the time of poking is serious when you are a beginner as well as an intermediate or advanced stage. Looking at the screen, the shoulders are pushed up.

Looking at the prior art relating to ski poles in various countries, there are mere upper and lower shock absorbers, which are disclosed in Japanese Patent Publication Nos. 53-128430, 52-147131, German Patent 2055597, and Swedish Patent 132429.
There are US Pat. Therefore, although some applications have been seen for nearly 10 years, the reality is that they have not been produced or sold as commercial products until now.

[0005]

DISCLOSURE OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION
In the above prior art, such as 28430, the grip of the ski pole is a cushion only up and down. But spring 1
It has a complicated air cushion structure with individual cylinders, pistons and O-rings. However, it is 0.30mm until it pokes through the tip ring of the ski pole and returns.
It is estimated that it takes about 1 second or more to recover because the following air holes are exhaled and inhaled. Although I am talking about protecting the human body with loose up and down movement, such as wedern downhill of advanced level, poking out, poking again, poking the same hand stock if there are obstacles etc. Due to the problem of a few hundredths of a second, a slow air cushion return such as the one mentioned above will cause the player to poke without returning completely, which may result in an uncomfortable feeling when struck, a large number of complicated structural parts, and durability. , Do not consider strength, weight, balance.

In addition, depending on the quality of snow, the return operation of the stock may be difficult to slip out due to solid snow, and the stock may not stick when the snow surface is hard. Therefore, the balance may be lost and each part of the human body may be damaged. Over a long period of time, it causes fatigue and sometimes injuries due to falls. From beginners to the highest level, it is said that skiers' strength and skill are to overcome them.

Therefore, all of the conventional techniques have problems in strength, durability, safety, light weight, balance, simplicity of mechanism, and performance, which are most important as stock. In addition, each of the above-mentioned applications suffers from a number of serious drawbacks in view of various conditions such as a small number of parts, ease of production process, and low cost.

Ski stocks have to be able to cope with all kinds of heavy exercises and various snow qualities during use, regardless of whether the ski is downhill or downhill. That is, the important conditions for ski stocks as practical products are listed below. (1) Light weight. (2) Good balance. (3) Strength and durability. (4) Things that can be done by a sports equipment store or an experienced person by simple adjustment of the stock length. (5) Minimize the impact on the snow surface,
It protects the human body and reduces fatigue over the short and long term. (6) To be able to quickly return and remove stock from the snow surface to compete for a few seconds in 100 minutes. (7) The degree of incision in the shaft tip ring part on ice burn should be high. (8) Stocks are often taken from heavy snow, heavy snow, etc., but that phenomenon should be reduced as much as possible. (9) The repulsive force of the buffer spring works effectively as a propulsive force to improve the time, regardless of whether the vehicle is skiing or gliding. (10) Applications such as alpine and Nordeck for downhill and gliding,
It can be manufactured according to the technical level. (11) Establishing safety to prevent danger in the event of a fall or collision is as high as possible.

The above items (1) to (4) are filled with the existing stock. However, (5) to (11) are supplemented by the skier's downhill technology, and are not yet provided in the mechanism of the ski pole itself.

A first object of the present invention is to provide a ski pole in which the shaft of the ski pole is kneaded and reciprocates vertically. A second object of the present invention is to provide a ski pole having a cushioning function in the grip portion of the ski pole. A third object of the present invention is to provide a ski pole as a practical product immediately by simplifying the manufacturing technique, simplifying the production process, and reducing the production cost. The fourth object of the present invention is to provide the above (1).
It is possible to deal with 11 items from (11) to (11) to a certain degree with a high degree, the structure is simplified, the number of parts and the weight are minimized,
The objective is to provide ski skis as a practical product immediately, with the production process and production cost set at the same level as the current high-end products.

[0011]

The contents of the ski pole of the present invention will be described below with reference to the drawings. The shape of the three-dimensional positive cam 4 is slightly changed in a small internal space called the palm grip 1 provided on the top of the ski pole, and the follower joint bolt pin 11 is used as a cam mechanism. This cam mechanism gives the shaft head 7 a reciprocating motion in the shape of a cone.
As a result, the above movement is transmitted to the thin and weak pipe shaft 6, and the strength and durability of the pipe head 6 and the follower bolt pin 11 are made the same as those of the conventional product. At the same time, the shaft head is able to hold the multi-stage cushioning cushion in a stable manner, fully exerting its cushioning function while maintaining strength and durability, and the tip ring portion is movable left and right.

The contents of the above-mentioned prior art and the convolution of the present invention, the upper and lower reciprocating multi-stage shock absorbers are physical elements, mechanical elements, and their movements are of different forms, and the technical purpose thereof is merely to protect human body from danger. Unlike the ones, it also has the purpose of improving skiing skills.

[0013]

(1) As for the lightness, the stock of the present invention has four parts (rubber-like cushion 8, long compression coil spring 9, short compression coil spring 10, driven node bolt pin 1) as compared with the conventional stock.
1) It is heavy because of the large amount. However, each of them is several g, and although the shaft head 7 and the grip portion 1 are a little large, the total weight of each member is about 20 to 10 g, which does not impair the lightness.

(2) As for the balance, since the above-mentioned excess weight is all in the grip portion, when the stock is ideally weighted, the tip feels lighter when it is swung forward and the balance is rather improved.

(3) As for strength and durability, the grip portion 1 such as the pipe shaft holding portion 3, the groove of the three-dimensional positive movement cam 4 and the hollow portion 5 is used.
And the members of the shaft head 7 and the follower joint bolt pin 11 are retained. Just like the principle of Japanese sword,
The palm grip portion 1 serves as a handle, the follower bolt pin 11 serves as a bamboo eye nail, and the combination of the shaft head 7 and the pipe shaft 6 is the blade portion. The relationship in which the force works is exactly the same mechanically. A cam mechanism is used in addition to this, looseness of the follower bolt pin 11 and twisting and strength of the thin and weak pipe shaft 6 are a concern.
Tighten tightly until it stops at the large head of diameter 1, shaft head 7 is a resin-based upper pipe shaft 6 of viscous material.
It fits tightly inside, and it also plays the role of a nut, maintaining its strength and looseness.

When the rubber-like cushion 8 inserted and fixed in the upper hole of the shaft head 7 is on the ceiling of the hollow portion 5 under the maximum pressure load that cannot be compressed any more when it is pushed to the maximum extent, the long compression coil spring 9, The short compression coil spring 10 has a space that does not reach the maximum compression. This is adjusted by the length of the protrusion of the shaft head 7. Further, the head of the follower bolt pin 11 is also made to have a groove length that does not attach to the upper ceiling of the cam groove at that time.

The reason for this design is that when the maximum pressure load is applied to the tip of the pipe shaft 6, the shaft head 7, the rubber-like cushion 8 and the palm grip portion 1 are transmitted from the shaft.
It is received by the ceiling of the hollow part 5. Therefore, the long compression coil spring 9,
This is to protect the short compression coil spring 10 and the follower bolt bolt pin 11 and improve durability. This is exactly the same as conventional ski poles, and its strength and durability are proven.

(4) The length is adjusted by disassembling it in the opposite process of assembling and cutting the pipe shaft 6 to a length suitable for the user. With the simple jig shown in FIG. 7, the screw hole 18 for the follower joint bolt pin 11 that fits the shaft head 7
Then, the pipe shaft 6 is attached to the jig, a hole is opened, and the pipe shaft 6 is reassembled. The jigs will be distributed to the sports equipment stores that sell them in advance.

(5) The problem of impact resistance is that when the ski is not used, the long compression coil spring 9 always presses and fixes the follower joint bolt pin 11 to the lowermost end of the three-dimensional positive cam 4 via the shaft head 7. Has been resolved. If you hit it on the snow surface, the long spring will come loose first and the short spring will work together. Furthermore, the rubber cushion 8
And the three work together strongly to obtain a three-stage buffer. When pulling out, it first returns with a strong instantaneous repulsive force, and loosely returns with a spring action opposite to the above. In the case of the grip portion 1a described in the examples below,
Furthermore, one-stage or two-stage buffers are overlapped to obtain more multi-stage, heavy and complex buffering property.

Although it is difficult for the above-mentioned multi-step spring action to give an accurate measurement value for human body protection, it is assumed that a senior adult skier who is a normal adult will have a slope of 28 degrees, a speed of about 30 km / h, and a Wedern downhill. In the room, the impact sensor was attached to the shoulder joint, and it was struck on the cedar board and measured. Conventional products average about 2.5
Before and after G, the present invention described in Example 1 described later recorded an average of about 1.5G. As a reference, the impact on the knee joints of a marathon athlete is 6.5 G, and when the same athlete is a bicycle, it is only 0.6 G at 20 km / h.

In this multistage buffer mechanism, as soon as it enters from the software, it returns to the hardware, and when it returns, it instantly returns from the hardware to the software. When the poking time is not the moment and is long for 1 second or more or weak, it acts in the intermediate zone while maintaining the cushioning property. Generally speaking, the beginners are in the soft stage, the intermediate are intermediate, and the advanced are often full buffer.

The ski stock designed with the spring of the cushioning material, which is suitable for the standard specifications, can sufficiently cope with the protection of the joints, muscles and nerves of various parts of the human body, the accumulation of fatigue, each technical level and the like.

(6) It is very important that the stock litter from the snow surface is as fast as possible when the tip ring part is struck, which is a very important factor when it comes to advanced ski slopes and ski slopes. It is a competition. Above (5)
The strong instantaneous repulsive force of the triple spring, which is seen in the latter half of the buffering action of, is a decisive help.

(7) The reciprocating motion of conical rotation of the pipe shaft 6 plays a role in the degree of cutting at the shaft end of the ice burner. When skiing an Alpine downhill ski, the left hand turns left, when the right hand swivels right, and when the Nordeck ski skis, turn it backwards. This is a method of providing the direction of inclination of the cam groove described in the fluid element of the three-dimensional positive cam 4 described later in Example 3, and the left and right rotation directions when the cam is struck are determined.

As is well known, when skiing downhill, the left-handed stock is the left-handed stock, and the right-handed stock is the right-hand stock. This means that the stock on the descending side, that is, the valley side is always used. In this case, the tip of the pierced stock must rotate either left or right, and it will rotate not up the bottom of the slope on the valley side but in the up direction of the mountain side. As a physical property, rotation proceeds in the rotation direction, and resistance occurs in the opposite direction. The tip of the stock rotates in the upward direction on the mountain side, and resistance occurs in the downward direction on the valley side. Therefore, along with the punching power, the hardness of the hard ice barn and the good stab quality increase. The goodness of slipping out of heavy snow, solid snow, etc. is that the ring 21 at the tip of the shaft does not move in the snow because it is movable, and only the central pipe shaft rotates in the opposite direction when the pipe shaft instantly strikes and pulls out. This is the same as a hand-turned cone for woodworking. Physically, the reverse rotation reduces the resistance of the substance, and the reverse rotation of the back and forth,
Although it is a little bit of the moment, it also has the effect of increasing the water content and adding a slipping element to improve drainage. The reason why the above-mentioned reverse rotation is applied to the gliding Nordeck is to make it easier for the wrist to turn inward when it is struck, so that the force is increased and the propulsive force is increased.

(8) Similar to the above (7), the tip ring 21 does not move in the snow because the tip ring 21 is movable, and the pipe shaft 6 does not move without sticking out from heavy snow or heavy snow. The reciprocating motion of the tip tucking and rotating plays a role.

(9) The repulsive force of the shock-absorbing spring acts as a propulsive force. The reason is that the part of the return motion after the shock-absorbing mechanism has struck as described in the above-mentioned problem of impact (5) has a natural shape. It helps. Of particular importance is that the strongest repulsive force occurs in the three-stage compound at the beginning of the return. All competitive skis,
Thousands of times and the force of the thrust arm and stock is one-third of the driving force
It will lead to a great improvement in the time required for the Nordeck's occupancy.

(10) As for the production corresponding to the use and the technical level, what is shown and described in the drawings is a standard specification design for downsizing of an alpine. The reason for the use, for example, for sliding a Nordeck, was described in (7) above. The left hand rotates to the right, the right hand reverses to the left, and the angle of the cam 4 is reduced,
The groove is long and the spring is strong. Even in the downhill, the springs are naturally stronger for professionals, superlatives, and racers. Broadly,
Both downhill and downhill are standard for general use, advanced use, beginner use, children use, etc. A beginner or a child can select vertical movement by setting the angle of the three-dimensional confirmation cam 4 to 0 degree. If you want to be extremely lightweight, do as shown in Fig. 3.

(11) As for the danger prevention, the problem of safety establishment when the tip of the stock sticks at the time of tipping over, collision, etc. It can be said that the cushioning effect is even more secure than the conventional product.

In general, the more expensive high-priced products on the market are lighter and more well-balanced due to the difference in materials. Not to mention beginners and intermediates, but especially at advanced levels, they become important factors. When I buy stock, I often see it holding in my hand and swinging forward, but I do not feel too heavy at hand,
The tip is even lighter, and it is said that it is good to be able to swing out to the person with a "soo" feeling. This is because more than two-thirds of the total weight is concentrated at hand and the shaft material is strong and light.

The weight difference between the prototype and the conventional product was about 12 g for one slide and about 18 g for the slide. However, in the prototype, the weight gain is concentrated at hand, so the balance is rather good.

The toughness and durability were tested on a wide range of levels from beginner to advanced seasons. Approximately 60 days, including how to slap that is considered benign to advanced users, and about 4 hours
Let it run for 80 hours. This is a person who loves skiing, which means that he has used it for about 6 to 8 seasons when converted to the normal average. There was no problem because the cam groove was shining smoothly with the scraping of the bolt pin 11. During that time, the number of reciprocations of the follower bolt bolt 11 reaches about 20,000 times or more.

The most worrisome point is the follower bolt pin 1
1 is the pressure load and the torsional strength of the shaft at the base of mounting the pipe shaft 6 of FIG. Despite the thin pipe, the shaft head 7 was tightly filled inside, so there was no problem with the conventional pipe shaft.

Finally, a destructive test was performed. Even if the middle of the shaft was broken, there was no damage to the structure or function of the grip. As mentioned above, this is due to the strength of the mechanical structure of a Japanese sword that also uses a cam mechanism, and from the shaft to the shaft head 7.
This is because of the structure and mechanism in which the maximum pressure load is applied to the rubber-like cushion 8 and the ceiling of the hollow portion 5 via the.

The performance and effect during use will be described. Stock operations by beginners are always slow and slow,
In particular, the action of pulling it back from the snow surface is ambiguous. There are many operations to drag the tip of the stock onto the snow surface, and it is said that the skill of the stock work can be understood by looking at the stock work. When observed by the beginners, the difference from the conventional product is that there is little shock when piercing. When pulling back from the snow surface, the repulsion of the return of the multi-stage spring that is strong first and fast and then weaker naturally pushes up the hand without dragging the snow surface. As a result, you will naturally teach important return operations. It also reduces the loss of balance. At the same time, the tempo to move to the next action became faster.

Although most beginners dislike stock operations,
On the contrary, the fun to use was amplified. Intermediates feel the need for stock operation, but have not yet fully utilized the effects of stock for various rotation techniques such as Christiania, Wedern, and tail jump rotation. The trial results were better than those of the beginners, and in particular, the important element that the operation of pushing the stock and the timing of rotation were integrated was noticeable.

[0037] For advanced riders and above, downhill speed, slope,
Depending on the terrain and snow quality, etc., it is powerful and quick, and the stock is operated according to the situation to assist in rotation. However, the joints such as wrists, elbows, shoulders and stapes, the cervical spine above the spine, the thoracic spine and its nerves, etc. are considerably impacted.
At that time and in the long run, the causes of injuries and illnesses such as muscle aches, arthritis, bruising, bruising, flesh, sprains, and dislocation of various parts are created. This is covered with physical strength and technology that have been trained for many years.

The first impression of using this prototype is about 3 of the conventional products.
I only feel a shock less than about one-third. In addition, the return of the return was incomparable, and the good result was obtained. Even at times other than turning, it shows high techniques such as air turn and balance maintenance by often pushing both stocks on steep slopes on uneven terrain. It was found that all of them worked reliably and had the same high stability as the conventional products.

At the same time, the repulsive force of the triple spring obviously assists the propulsive force when competing for 1 / 100th of a second such as skiing on skiing or downhill skiing. It turns out that it will improve the time. In addition, the trial results of the Nordek for sliding were compared with the conventional products by dividing the total over 50 km several times. Approximately 20,000 times, the accumulated record for a long time of use clearly shows the combined effect of the repulsive force of the multi-stage buffer spring, the good sharpness of the hard ice with a conical mass, and the good shedding of heavy snow. ,
The same person made a difference of about 12 seconds at 10 km after several attempts (although there are physical conditions, etc.). Obviously, it will be an auxiliary effect of the driving force and will lead to the improvement of time.

In addition, reduction of fatigue and comprehensive protection of the human body in each part such as wrist, elbow and shoulder joints, cervical vertebra above the spine and thoracic vertebra are great. Both the downhill and the downhill on the paved road in the city just wear orthodox leather shoes and walking shoes 10
If you walk km, the result is the same as clear.

Next, the trial effect on the snow quality will be described. First of all, the quality of snow changes every moment depending on the weather, temperature, time, season, etc., but the snow quality for skis can be roughly divided into dry powder snow, powder snow, ordinary snow, and stepping on skis. Not fresh snow, ice burns, heavy, heavy snow, bad snow, and other things that are rarely seen on the slopes, but are roughly divided into sun crust and wind crust. There are three snows that skiers are happy with. You can ski like a ski The latter five bad snows are difficult to glide and require higher technology. In addition, there are many dangers of falling, leading to accidents. However, in fact, more than 60% of the whole period is the latter snow except for spring skis, and recently, except for skiing skis, it is pressed and hardened from the beginning with a caterpillar car to make the snow on the slopes last longer.

The conical reciprocating motion is due to bad snow such as the latter. The first point is the degree of cut at the tip of the ski stock on the ice burn. No matter if you hit the left or right, the tip rotation is always turning toward the higher side of the mountain side, so compared to the conventional product, the cut on the hard ice snow surface and the catching are clearly improved. As a result, the escape and slippage of the stock tip were reduced, the balance was lost, and falls were reduced.

In addition, any skier has experienced that heavy snow or heavy snow cannot be removed after hitting the stock and the stock can be caught on the snow surface. I understand the difficulty of slipping in bad snow and the cautions for accidents so that I am a veteran. I wonder why the tip of the stock to the ring, which is less than 10 cm from the stock, sometimes becomes difficult to pull out. If you carefully observe the conventional product during implementation, you will find that it is difficult to pull out the shaft when it is fixed.

The tip of the shaft of the present invention does not move in the snow because the ring is movable, and when only the pipe shaft is struck,
When pulling it out, the inside of the snow is agitated by the conical rotation. The kinetic energy of the rotation itself and the resulting increase in water content around the hole in the snow pushed the hand unconsciously by the spring action of the return, resulting in a triple effect, and good results were obtained. Most of the above-mentioned effects are great considering that the injuries caused by accidents are mostly caused by falls and are concentrated especially during heavy snowfall or heavy snowfall such as ice burn.

It is not possible to experience an accident in which a human body at the tip of the stock is stuck due to a collision, a fall, etc., so 30
I experimented with pork with a skin of about kg. I was worried because the shaft had a conical motion, but the rotation angle was 50.
The result is disappointing because it is small and around. After all, the effect of cushioning is clear, and if you gradually increase the strength with the same strength as the conventional product, the conventional product will stab at a stage above a certain force, and the prototype will only pull in the skin strongly. I was there. It was even stronger, and the prototype was stuck in it as it approached the limit that an ordinary adult man could put out. After all, sticking is a matter of strength and angle. The answer is that the risk prevention and safety establishment are much better than the conventional products.

Next, there will be described the problem of whether or not there is an obstacle in the function of performing a normal motion when snow is clogged in the groove of the stereoscopic positive movement cam 4. The experiment was carried out under conditions of night skiing in Hokkaido at 22 ° C below zero. The groove was artificially filled with snow and left outdoors for about 30 minutes. The snow was suddenly used for trial, and the experiment was repeated many times. The head of the follower bolt pin 11 strongly moved up and down with respect to the volume of the groove, and it smashed by being struck a few times, and there was no problem.

[0047]

EXAMPLE FIG. 1 is a cross-sectional view of the grip portion of this ski pole as seen from the side. However, since the three-dimensional positive cam 4 is oblique, the vertical cross section cannot be cut halfway from the center of the upper part. This is indicated by the cut section lines 12, 13, 14 in FIG. FIG. 2 is a perspective view from the vertical front, and the sectional line of FIG.
2, 13, and 14 are shown. FIG. 3 is a step view seen from the same position as FIG. 1 showing that the three-dimensional positive cam 4 can be provided on the grip portion 2.

EXAMPLE 1 As shown in FIGS. 1, 2, and 3, the ski pole of the present invention comprises a grip portion 1, a pipe shaft 6, a ring mounting bracket 19 and a ring pressing bracket 20 shown in FIG. It is composed of a tip ring portion including a ring 21 and a tip stone fitting 22 which are attached so as to rotate in the direction of. The palm grip portion 1 has an integral structure having a shape that fulfills the function of each element, and the grip portion 2, the pipe shaft holding portion 3, the three-dimensional positive cam 4 and the movable portion perform a conical movement and a vertical reciprocating motion to hold it. It consists of a hollow part 5. As shown in FIGS. 5 and 6, the rubber cushion 8 is inserted into the hole of the uppermost projection of the shaft head 7 of the pipe shaft 6, and the long compression coil spring 9 and the short compression coil spring 10 are fitted into the projection cylinder in this order. . This is inserted into the hollow portion 5 of the palm grip 1 as shown in FIG. 6, and is inserted until it stops at the upper step in the palm grip 1.

Next, the groove of the three-dimensional positive cam 4 of the grip portion 1 and the screw hole 18 of the follower bolt pin 11 are aligned. From the smaller diameter of the follower joint bolt pin 11 having a diameter of three steps from the groove and having a thread in the central portion, screw in until it stops at the head with the larger diameter, and tighten. This completes the assembly of the ski pole. As the material of the grip portion 1, light metal, carbon fiber, ceramics or the like can be used. However, synthetic resin is generally used for integral molding.

Embodiment 2 In the second embodiment of the present invention, a composite structure in which two or more materials and members are combined is added to the integral structure of the palm grip portion 1a in order to further enhance the cushioning property in multiple stages. FIG. 4 shows the grip portion 1a of this embodiment. The palm grip portion 1a is made of a cushioning material (rubber-like), and has an outer grip portion 2, a second hollow portion 5B, and a head bolt hole 17 formed in the uppermost portion.

An internal cylinder 15 is incorporated in the palm grip portion 1a. The inner cylinder 15 is configured to have the pipe shaft holding portion 3, the three-dimensional positive cam 4, and the hollow portion 5, and is made of a hard material. A mold of the grip portion 1a is attached to the inner cylinder 15, and a cushioning material is poured and wrapped so as to be molded. Depending on the selection and combination thereof, both materials in this regard are one in which the palm grip portion 1a and the inner cylinder 15 are naturally adhered and one in which they are separated without wearing. The former comes in one type and the latter comes in two types: two-stage cushions. In the latter, the inner cylinder 15 is fixed with a bolt from the head bolt hole 17 at the top of the palm grip portion, and the palm grip portion 1 is also fitted with the palm grip portion fixing projection 16.
Hold a completely. This further increases the multi-step buffer.

Embodiment 3 In the two types of gripping portions of the above-mentioned integral structure and composite structure, the upper and lower side surfaces of the two grooves of the three-dimensional positive cam 4 are always at right angles to the cylinder of the hollow portion 5, and part 2 The two grooves are always provided at the same angle with respect to the hollow portion on opposite sides. A groove having a width that allows the diameters of the circles of both heads of the driven node bolt pin 11 to be movable, and is a vertical straight bisector 1 of two grooves along the section line of FIG.
When 3 and 14 are connected by a straight line perpendicular to the center line of the hollow portion 5, all the straight lines pass through the center line of the hollow portion 5 and have an invariable property.

Each of the elements other than the above is a groove inclination angle of 0 ° to about 75 °, and the pipe shaft 6 rotates left and right for the left and right conical rotation when the protrusion is made, and the length of the groove is about 10 mm.
To 70 mm, and the position of the groove can be provided within the practical upper limit of the pipe shaft 6 and within the entire circumference of the grip portion.

Therefore, in addition to the above-mentioned invariant properties, in order to correspond to the purpose such as downhill, gliding, and the like, technical level, etc.,
The three-dimensional positive-moving cam 4 has a property of inevitably corresponding change from the necessity. As a result, the strength and quantity of the various cushions for cushioning, the shaft head 7, the pipe shaft holding portion 3, the driven joint bolt pin 11, the left and right movement of the tip ring 21, and the functions, sizes, and shapes thereof correspondingly change.

The changes in each of these elements and members are within the permissible limits of the practical range, and each function of skiing and gliding, the skill level of the user, and the optimum function and structure of a ski stock suitable for their purpose To address each of the 11 issues from (1) to (11) above.

As a prototype, two points were prepared, one for gliding and one for gliding. In order to get an accurate comparison with the conventional product, we bought the same conventional product for downhill and sliding, and bought two points each, one with the palm grip removed, and the tip ring left attached to allow left and right rotation. The pipe shaft 6 was used and other parts were newly made. The other point was used as it was for competitive comparison with the prototype. The prototype for downhill was manufactured as shown in Figure 1. The rotation angle of the pipe shaft 6 is about 5
0 degrees, the round trip length of the shock absorber is about 20 mm, the rotation angle for sliding is about 30 degrees, the round trip length of the shock absorber is about 30 mm, and the spring is made strong. In order to respond to different needs, we conducted a test to determine the strength of each of the five strengths, and selected the best from them.

[0057]

The effects of the above (1) to (1)
The effects up to 1) including the feeling of use and anxiety when snow becomes hard ice in the groove of the three-dimensional positive cam are described.
As the number of times the ski poles of the present invention have been used increases, the advanced skier feels that the skis have a shock and feels like they have not been used, and the evaluation is that the same effects as the conventional products are obtained without any discomfort. The work that changed and was able to return immediately after entering the software was well received.

Although it is simple and simple, it is a mechanism that can exert important elements and functions in a mutually related and assisting structure. Moreover, the number of parts, weight, production process, cost and balance are almost the same as the conventional products. Various effects such as improvement of technical level over a number of items, reduction of accumulation of protective fatigue of various parts of human body in short and long term, and enhancement of safety were brought out.
