Description

Land swimming simulator

This creation is a machine for practicing swimming on land. See the first and third figures. For the Jet and Backstroke, this creation enables the body to make the action of rolling in the same place, and then with the ventilation sink, to simulate the posture of the body rolling and the ventilation during swimming in the water, and not for the butterfly and breaststroke. The swimming style that needs to roll the body, the setting of the ventilation sink can practice the breathing of the butterfly and breaststroke and the rhythm of the hands, feet and head. This creation uses a slanted panel to support the body, keeping the body at the same slope as swimming in the water. The length of the slanted panel covers the full length of the human body and all parts of the body are supported. The palm support section is fixed to the lower surface of the foremost section of the slanted panel and can be extended to the outside to simulate the posture in which the arm extends into the foremost position. The rower guide group is suspended below or outside the inclined panel to simulate the pulling, pushing and returning of the arm. The ventilating water tank is filled with water for the ventilation of the simulated mouth and nose. Rolling the body section causes the upper body to make the necessary rolling motion. The kicking section of the leg simulates the action of kicking the water on the instep with the instep, and gives the necessary support when the foot does not kick the water. In addition to the kicking exercise for the instep, the joint action with the rower and the ventilation is finally done. .

The first point is that in the body rolling movement during the simulated swimming, the prior art is all rotated by the axis of the flat plate, and then the elastic body such as a spring is used as the supporting structure and the recovery mechanism which are inclined to the left and right. However, the flat plate is rolled at its roll center, and the person is hung on the flat plate. The rotation center of the human body is higher than the roll center of the flat plate, and does not overlap. Therefore, the center of the human body is swaying relative to the roll center of the flat plate, instead of The rolling motion of the human body's own center of rotation is performed, but the pendulum movement is reversed with respect to the center of rotation of the flat plate. In actual operation, see the fourth figure. When looking from the front direction, the center of the head is off centerline when rocking. The head and the body are shifted left and right and the height is high and low. The greater the swing angle, the more the shaking is. This is completely different from the swimming in the body axis. When you actually swim in the water, the body is Rolling forward and straight forward, it will not shift left and right.

Secondly, the prior technique of rowing practice is to use the pull cord to train the arm movement, and the two arms interact to pull the rope to simulate the stroke movement. When the hands are gripping the handle, the angle between the palm and the forearm cannot be practiced when the stroke is made and the water is pushed. Change, when the hands are stuck on the stencil, they can't completely relax. When returning, the arm muscles are not completely relaxed like swimming. The drawstring does not provide a clear path for the rower.

The third point is that there is no setting on the land-based teaching machine (see the first figure) to make the swimming training combined with the hand and the foot. Instead, the practice of ventilation and hands and feet is carried out in the water. The action, while doing the ventilation in the water, is often stunned by the uncoordinated rhythm of the hands and feet, and becomes a major bottleneck for learning to swim.

The present creative embodiment (see the second figure) utilizes a slanted panel to provide the weight of the support body. The slanted panel is regarded as a buoyancy providing machine, and the slanting panel is used instead of the water slab because the person is relatively horizontal when swimming. There is a slope. The slanting panel keeps the body at a certain inclination and maintains the body posture like swimming in the water. So you can practice in a static position and concentrate on the decomposition of a certain swimming. You don't have to worry about being under the body when practicing in the water. It’s a mess. The front end of the slanted panel is narrower than the back to facilitate the rowing. The front end can be opened with an opening (see the right half of the eleventh figure), and then with the transparent ventilation sink 2 (see the twelfth figure). You can see through the slanting panel and look directly at the front and lower scenes. You can see the front of the pool when you swim, so that the focal length of the eyes can be far away and feel comfortable. This creation is to move all the exercises in the water to the land.

First, the mechanism for practicing the stroker movement (see the first figure): When the panel is slanted up and down, there are anti-slip mats on both sides of the front half of the slant panel, and the two sides of the slant panel are supported by both hands. A palm support section is arranged at the forefront of the slanted panel, and a sliding guide group of the space below the slanted panel is used, and the two are used together to perform a full set of rower movements, and the palm support section guides the arm forward to the foremost position and Position the palm in the forefront to avoid sagging, and temporarily wait for the rowing action; the rower guide group, in terms of the quickstroke and backstroke, the pull plate on the rail is interlocked with the rope (see Figure 6). One forward and the other backwards, providing two-armed interactive rowing exercises; in the case of butterfly and breaststroke, the pull-pull plate on the slide of the sliding guide group is independent of the automatic retracting rope at the forefront of the sliding rail. For sports (see Figure 7), the two pull plates can be pulled back and pushed back together. After the hand is removed, the automatic retracting rope will automatically return the two push plates to the foremost position, providing two arms synchronization. The practice of rowing.

The body rolling section on the inclined panel is used together with the rolling element group (see Figure 8) and the curved panel (see Figure 9) to drive the body to roll around with low friction. The most important thing is to roll. Keep your body on the centerline and keep your head in place (see Figure 5). The rolling element assembly has the function of supporting and rolling itself to minimize the rolling friction between the curved panel and the curved panel. The bottom of the curved panel has a circular arc shape to produce the effect of rolling in place. The top surface of the curved panel should support the upper body of the human body, so the mat should be made with the contour curve of the upper body of the body, so the bottom of the curved panel is a circular arc and the top surface. It is a U-shaped surface that is flatter than the bottom, making it comfortable to lie down. In addition, in order to prevent the curved panel from sliding backward, the trailing edge of the curved panel is contacted and blocked by the anti-slip roller, and the anti-slip roller is fixed on the inclined panel (see FIG. 11 and FIG. 19). Another mechanism on the front side of the slanting panel is a retractable elastic indicator rod (see the second picture). It is designed for the Swim and Butterfly. When the stroke is backward, the elastic indicator rod will bend and let the arm pass, then bounce back. Position, when the arm moves back to the hand, it indicates that the backhand should have a height, avoiding touching the water surface when swimming back in the water, the arm must be raised higher than the elastic indicator rod, just like the backhand needs to be higher than the water surface when swimming .

Second, the mechanism for practicing kicking: There is a slanting kicker pad in the second half of the slanting panel (see Figure 14). The slanting kicker pad has a surface that is inclined downward with respect to the slanting panel. This slope simulates the kicking of the instep to the deepest position. It provides the practice of kicking the water in the butterfly and the instep, or the practice of tilting the soles of the soles of the feet, so that there is room for downward movement below the thighs and below the calves. For the breaststrokes, the thighs are separated from the left and right sides. They are viewed from the front or the rear of the swimmer. When the legs are retracted, the inverted V-shape is formed between the two thighs. Therefore, the creation of the general rectangular mat is cut into a bevel to make the mat The left and right sides do not interfere with the leg-retracting action, and the two inclined surfaces are used to guide the two legs to contract forward. The uppermost end of the cushion retains a narrow strip area that can support the legs and straighten up, for the legs to finish backwards. It can be supported when it is kept close and stretched after the action. Breaststroke tour The swimming simulator replaces the inclined kick pad with the kick pad for the breaststroke, and converts the front end of the slide guide group into the automatic retracting rope to connect the pull plate so that the hands can move synchronously and replace See Figure 10 for an example of a swimming simulator for a breaststroke swimming kick pad.

Third, practice the joint action mechanism between the rower and the kicker: practice the strokes of the stroke and the kicker in the slanting panel, for example, a rower with three kicks, and use the roll of the body roll section. Turn function, drive the chest and abdomen together to do the left and right rolling movement, so that the matching of hands and feet is like the actual swimming (see Figure 18). For the butterfly and breaststroke, although you don't have to turn your body, you can still use the right-rolling characteristics of the body roll mechanism that has been installed for the Jets. When practicing the rhythm of the head and hands and feet, the training keeps the balance of the body. .

Fourth, practice the mechanism of hand, foot and ventilation: During the ventilation exercise, place the ventilation sink in the position with the frame at the forefront of the inclined panel (see the second figure). The inclined panel is used as the border in this area. The ventilating practice sink is firmly inserted into it to avoid displacement of the ventilating sink due to collision. It is a good choice to use a transparent ventilation exercise sink, because the front end of the inclined panel can be opened with an opening, and the transparent water tank is supported by the inclined panel around the opening, and the transparent water tank and the front opening of the inclined panel are visually seen, and the front of the inclined panel can be seen. The scenery below makes the eye's focal length and head posture the same as the swimming in the water. The eyes are not uncomfortable because the oblique panel blocks the line of sight and looks at the scene shorter than the bright distance. The front and left and right sides of the ventilating tank wall can be attached with a mirror surface so that people can see their own ventilation, so that they can grasp the timing of exhalation and inhalation. In addition to the backstroke, the face-up exercises are not required to change the air tank. Butterfly, Jet and Breaststroke can use the air-sink to practice ventilation and practice the rhythm of rowing and kicking. This creation replaces the buoyancy in the water with the support of the inclined panel, so that the body maintains the swimming posture, and then uses the modules above and below the inclined panel. Including the palm support section, the ventilation trough section, the body rolling section, the leg kicking section and the rower guiding group, a swimming simulator based on the Jet Swimming is created. Figure, and can replace some modules for backstroke, butterfly and breaststroke exercises.

The swimming simulator for backstroke, all modules can be extended to the swimming-based swimming simulator, just change the position of the ventilation sink to the headrest for backstroke to support the hindbrain, and the rowing guide group to the floor. The bracket is supported on the left and right sides of the inclined panel to adjust the distance between the user's body and the slide rail; in addition, the palm support section can be shortened to the shortest, and is not required for the backstroke. See Figure 15 for an example of a swimming simulator for backstroke.

The swimming simulator for butterfly swimming, all modules can be extended to the swimming simulator for the swimming. The only part to be replaced is to use the automatic retracting rope at the front end of the sliding guide group to connect the push plate. Can move in sync. See Figure 16 for an example of a swimming simulator for butterfly swimming. If it is dedicated to butterfly swimming, the position of the original body rolling mechanism can be replaced by a common cushion to form a butterfly swimming simulator. For one specific embodiment, please refer to the 20th.

The swimming simulator for breaststroke replaces the position of the inclined kick pad of the swimming simulator for the breaststroke with the kick pad for the breaststroke, and connects the front end of the slide guide group to the automatic retracting rope. Pull the board so that both hands can move in synchronous motion. This design has been explained in the tenth figure. The swimming simulator for the breaststroke has two modules that are different from the swimming swimming simulator. That is, it is not really necessary to use the body rolling mechanism and the breaststroke kicking pad, and the same place is the extension of the palm support section. The rowing guide group, the ventilation sink and the inclined panel, so the swimming simulator designed for the frog type can replace the body rolling mechanism with a common cushion, and then with the frog type kicking mat, and the sliding hand guiding group The front end of the slide rail is replaced with an automatic retracting rope to connect the pull plate. For the purpose of breaststroke, one example of a breaststroke swimming simulator is shown in Figure 17.

The most important feature of this creation is the design of the body rolling mechanism, which is matched with the inverted T-shaped table legs for support, and the inclined panel with the lower surface emptied, so that the water in the water and the backstroke roll body and row and kick The movement of the foot can be made on land without being restricted by the ground support, so a basic swimming simulator can simulate the swimming movement as long as the body rolling mechanism is installed in the first half of the inclined panel.

Because the side ventilation and rolling body are the necessary actions of the Jets, the Jet is the most difficult type of swimming in the four types on the land. Here, it is based on the underwater movements of the simulated Jet, including the arm. Water strokes, kicks in the legs, body-rolling around, turning around, and so on. Use this creation to practice a single exercise, such as rowing, and then add to two exercises together, such as rowing with kicking exercises or rowing with breathing exercises, and finally add to the rowing, kicking and breathing exercises together . In order to achieve a full set of swimming exercises in the simulated water, the first step is to have a flat plate that is sufficient to support the whole body weight, and the flat plate is tilted from front to back with the head as the front and the rear of the foot. This inclined surface is arranged by a straight line. Supported by the table legs 5, here supported by three inverted T-shaped table legs, from front to back, respectively, the longest table legs 53, the longer table legs 52, and the shortest table legs 51, so that the flat plate on it A slanted panel 1 simulates a posture in which the body's head is slightly higher than the foot when swimming. The left and right sides of the front half of the inclined panel 1 are provided with a non-slip pad 9 for the user to support the palm of the upper and lower sides of the creation. The front end of the slant panel 1 can be opened with a slanted front end hollow opening 11 and a transparent ventilating water tank 2, so that the eyes can comfortably see through the front and bottom of the slanting panel, just like the front and bottom of the pool when swimming (see the eleventh Figure). The ventilating water tank 2 is mounted on the slanting panel of the slanting panel front end hollow opening 11, and the slanting panel 1 has a ventilating water tank positioning edge strip 21 for fastening the ventilating water tank 2 or a ventilating water tank positioning pin 22, so that the ventilating water tank 2 It is stabilized on the slanting panel 1 and is not displaced by the collision, or is directly embedded in the slanting panel front end hollow opening 11 by using the compliant air-conditioning water tank 24 (see the thirteenth diagram). The front, left and right sides of the ventilating water tank 2 can be mirrored 23 (see the twelfth figure), so that the user can see the situation of the ventilating water surface such as butterfly, breaststroke and jet swimming. For backstroke, because the mouth and nose are up and can rise to the surface, it is not necessary to use the ventilation sink 2 to practice ventilation. Instead, a backstroke headrest 26 is used to support the hindbrain. When you want to practice breathing, put the ventilation sink 2 in the front of the slanting panel 1 The side strip 21 or the ventilating trough positioning pin 22 (only need to place the sink when the basic hand and foot are matched, see the eighteenth figure), the venting tank 2 can adopt the single layer or multi-layer side layer design The multi-layer gas exchange tank 25 is not afraid that the water in the innermost layer will overflow the water directly to the outside because the head sinks too deep, because the squeezed water can first flow to the adjacent layer space for storage (see Fig. 12). After adding water to the ventilating water tank 2, the mouth and nose are submerged into the water, and while blowing, while turning the head, the hand is stroked, and the body is also rolled. When the nose and mouth leave the water, the air will spurt, and then suck one. Breath, at this time, using the mirror 23 next to the ventilation sink 2 to see if the ventilation is correct.

Jets' strokes are two hands alternately stretching forward and then backwards. In order to guide the arms forward, there is a palm support section 7 in front of the inclined panel. When the hand is practiced, the arm is extended to the forefront and is used as the palm of the hand. Positioning area and waiting for the water-drawing area, first adjust the telescopic rod 71 to match the length of the arm forward, and straighten the arm that has not yet been drawn, so that the palm extends flat on the palm support plate 72, and bends when the water is stroked. The wrist is moved downward to the front of the pull plate 62 to which the row guide group 6 belongs, and the pull plate 62 is pulled backward (see FIG. 14). The telescopic rod 71 of the palm support section 7 is fixed by the bracket. The bottom surface of the front panel of the slanting panel is parallel to the ground. When the swimming is simulated, the arm is horizontally extended forward to reduce the forward resistance. The length of the telescopic rod 71 is adjusted according to the length of the arm of different people, so that the palm support on the telescopic rod 71 is supported. The plate 72 is temporarily placed horizontally with the palms of arms of different lengths. Because there is also buoyancy for the forward arm when swimming in the water, the palm support section 7 is designed on the land to simulate, if the hand that stretches in the forefront is suspended in the air due to unsupported, it will be drooped by gravity, which will affect The balance of swimming posture and the streamline of the body.

For the practice of arm strokes, for Jets, the rower guide group 6 below the slanted panel 1 of this creation (see Figure 6A and Figure 6B), where the rail 61 system has a sling The slide rail 61 used by the wheel 66 or the slide rail 61 used with the slider 67 is used for linear sliding. Taking the slide rail 61 for the hanging wheel 66 as an example (see the third figure), the two slide rails 61 are suspended on the slide rail bracket 65, and each of the slide rails 61 has a hanging wheel 66 that can slide back and forth freely. The two hanging wheels 66 are connected by a rope. The rope is a linked rope 64. Therefore, the two hanging wheels 66 are pinned and interlocked with each other. A pulley 63 is arranged at the end of each sliding rail 61 to reduce the pulling rope 64 from pulling back and forth. At the time of friction, the lifting wheel 66 is provided with a push-pull plate 62 for the palm to perform the practice of pulling water and pushing the water. When the pull-pull plate 62 is pulled backwards (practicing stroke action), the other push-pull plate 62 is The rope 64 is pulled to the front end, ready for the other hand to do the next stroke exercise, so the rhythmic interactive exercise arm strokes the same as the water stroker posture, when the water push action is completed, the arm When returning to the foremost palm support plate 72, a pair of foldable elastic indicator rods 8 are provided on both sides of the front half of the inclined panel 1, and the watered arm can be temporarily bent and restored to the original position to remind the arm. When returning, raise the height beyond the elastic indicator rod 8 to avoid water resistance during actual swimming. After the operation, the elastic indicator bar 8 is not required to be folded under the inclined panel 1. The rower guiding group 6 is completely independent and can be moved to any position. For the backstroke, the rower guiding group 6 will be supported by the floor stand 69, placed on the left and right sides of the body, and the floor stand 69 is moved. Keep a proper distance from the user so that the palm can just push the push plate 62 backwards. See Figure 15 for the operation of the backstroke. For the butterfly stroke and the breaststroke, the two hands are drawn backwards together. At this time, the front end of each slide rail 61 is converted into an automatic retracting rope 68 (see the seventh figure), so that the pull plate 62 can be synchronized, guiding the double The hand is drawn backwards at the same time, and the automatic return to the forefront.

The body drum type swings to the left and right, which is the center of the rotation of the body axis, which is the focus of the creative swimming posture (see Figure 19). Previous creation, Bulletin No. 283975, Swimming Trainer Structure, 1996/08/21, Yang Rentian; Announcement No. 331744, Swimming Fitness Exercise Equipment, 1998/05/11, Zhou Qihui; Announcement No. 200948430, Swimming Action Training Device, 2009/12 /01, Qiu Jinghua; Announcement No. M424169, swimming practice equipment, 2012/03/11, Chen Hefa, etc., the creation of the body roll, a rotation axis 39 is set at the center or below the body support pad 38, so that the body support pad 38 can be rotated left and right. The left and right sides of the lower surface of the body support pad 38, or the elastic member 391 is used to support the body support pad 38, so that the body support pad 38 can be tilted left and right without flipping over, and the user lying on the body support pad 38, The user's body axis 37 is higher than the rotational axis 39 of the body support pad 38, causing the user's body axis 37 to perform a pendulum motion about the rotational axis 39 of the body support pad 38 rather than the user's body axis. The center of the heart 37 is rotated. It can be clearly seen from the fourth figure that the user's body axis 37 is constantly moving left and right away from the center point and up and down during the movement, which is only when the body is actually swimming. There is no difference between left and right offset and high and low. In the backstroke exercise, due to the highest point of the head at the eye and the farthest position from the rotational axis 39, the swing radius is the largest, so that the head is obviously shaken and may cause dizziness .

In order to solve the above-mentioned problems, the present invention is fixed to the inclined panel 1 by using at least two rolling element groups 32 of small frictional force such as rollers or balls as a support and sliding base, and has the functions of support and rolling. Then, a panel 31 (see the ninth diagram) is placed on the rolling element group 32, and the curved panel 31 is in contact with the rolling element group 32 to perform a rolling motion together, and the sliding friction is small, lying on the curved panel 31. It is easy to make a left and right rolling motion and the body does not shift the center point, and the head does not sway. The bottom of the curved panel 31 has a circular arc shape to make an in-situ rolling effect. Since the curved panel 31 is a circular arc, the rotational axis 39 is a circular center position of the circular arc extending from the arc of the segment, and the built-in heightening pad is built therein. 33, used to fill the gap between the bottom of the curved panel 31 and the chest and abdomen of the human body, one is comfortable to lie on the top, and the other is to use the heightening pad 33 to raise the height of the human body and adjust the level of the body axis 37 of the user. It is equal to the horizontal height of the rotating shaft 39 of the curved panel, so that the two axial centers overlap, and when the curved panel 31 is in the rolling motion, the body is simultaneously driven to the body axis of the user. The heart 37 makes an in-situ rolling motion to simulate a rolling motion in which the body does not shift when swimming in the water. When the rolling angle is increased, the curved panels 31 are curved upwardly on both sides to provide good support on the side of the body, and Make sure that the user always rolls inside the curved panel 31 (see the fifth figure), while the user's body axis 37 is always centered, never exceeding the support range of the rolling element group 32 below the curved panel 31, so Will fall to the ground. The trailing edge of the curved panel 31 is in contact with a slip roller 34 (see FIG. 11), and the slip roller 34 is fixed to the inclined panel 1 for preventing the curved panel 31 from being on the inclined panel 1 having an inclined angle. It will slide backwards. The anti-slip roller 34 is a rotatable bearing that will rotate with the curved panel 31 rolling left and right to reduce the resistance of the curved panel 31 to roll. The left and right edges of the curved panel 31 are provided with an adjustment stopper 35 (see the third figure), and the angle of the right and left rotation of the curved panel 31 can be adjusted. For example, when the stroker is engaged with the kicking practice, the body does not need to roll too much. When it is large, the adjusting block 35 is fixed to the lower hole 36 on the side of the curved panel 31, so that the curved panel 31 rolls in a small angle, for example, rolling within about 30 degrees; During practice, the body needs to make a large roll to facilitate hand movements. For example, when the roll angle is as large as 30 degrees above the horizontal line, the adjustment block 35 is fixed to the higher hole on the side of the curved panel 31. 36, the curved panel 31 can be rolled out to a large angle to facilitate the practice of turning the head to ventilate.

The leg kicking exercise is to simulate the inclination of the whole leg to the deepest position by the inclination of the inclined kick pad 4, and the inclined kick pad 4 is a triangle as seen from the side thereof, and is disposed in the second half of the inclined panel 1 In the segment, it is a slope that slopes more downwards. The purpose is to create a space for the leg to kick down. When kicking the water, the body spine line is used as the reference line, the hip joint is used as the swing joint, and the leg is kicked down. The sole of the foot is inscribed in the shape of a foot, and the instep is kicked toward the inclined kicker pad 4 to produce an effective kicking water (see Figure 14).

Another type of kick pad that cooperates with the breaststroke is a breaststroke kick pad 41 that is placed to tilt the kicker pad 4 to be tilted to the left and right sides, and is characterized in that the area of the top is smaller than the area of the bottom. The plane of the top is inclined downward from the left and right sides of the lateral direction, and is an isosceles trapezoid when viewed from the front and rear, please refer to the tenth figure. When practicing breaststroke, the position of the tilting kick pad 4 used in the original swimming stroke is changed to the breaststroke kick pad 41, and the installed body rolling mechanism 3 can be retained, and the body rolling mechanism 3 can be used for practicing. The left and right balance of the body during breaststroke is also very good. For breaststroke training only, the body roll mechanism 3 originally designed for the Jet and Backstroke can be replaced with a plain pad 392 to save costs. The ordinary pad 392 is used directly to support the user's breast swimming for the upper body. See Figure 17 for the simulator. When practicing the butterfly stroke, retaining the body rolling mechanism 3 does not affect the practice of the butterfly stroke at all, and can practice the left and right balance of the body by facilitating the body rolling mechanism 3, so the body rolling mechanism 3 of the practice swimming stroke is matched with the inclined kicking foot. Pad 4 can be used directly for butterfly strokes without any changes. It is of course also possible to replace the body rolling mechanism 3 with a plain cushion 392 as in the breaststroke. For the part of the rower guide group, the butterfly stroke and the breaststroke are the actions of the two hands to draw backwards. At the forefront of the slide rail 61, the automatic retracting rope 68 is modified (see the seventh figure) to make the push plate. 62 can be synchronized, and the push plate 62 can be automatically returned after the hands are released.

The main advantage of this creation is that the body is fully supported, allowing the user to have sufficient time to think about the movement. For an unfamiliar single movement or more than two combined movements, the hand or foot can be held in a certain position, and the other exercises can be slowly practiced. Actions, unlike when doing action in the water, are limited by factors such as floating time and limited air-closing time. Each time you can practice for a short time, when you do two actions together, such as rowing your hands and raising your head, you often feel nervous. The rhythm is out of balance.

The second advantage of this creation is that it saves time for swimming pool exercises before and after changing, showering, and warm-up exercises. Once you are on the land swimming class, you can lie directly on the creation and practice immediately. You can practice time compared to the pool practice time. More, the learning progress is faster. If every student can complete the swimming training quickly, all students can learn to breathe in the air before the national small, which can greatly reduce the drowning event.

The third advantage of this creation is to replace the swimming pool as the only place to teach swimming lessons. Each class has to use the swimming pool in turn, and the swimming time is limited. As long as the school uses an empty classroom to prepare a sufficient number of original creations, the swimming simulation course can be implemented throughout the year, and each student in the class can practice simultaneously. One password and one action, the teacher corrects the action back and forth. However, students can practice without stopping, without having to wait for the guidance of the teachers one by one. After the onshore training is approved, the practice will be reduced, and the time and cost of going to the swimming pool will be greatly reduced.

The fourth advantage of this creation is that the manufacturing cost is low, the follow-up maintenance is cheap, and in winter, only one face of warm water can practice swimming, saving tens of millions of pool construction fees and millions of pool maintenance fees per year, reducing the school. Funding burden. For swimming teaching without swimming pool school, you can use this creation to familiarize students with swimming movements, pass the test of the swimming rhythm of the land, and then take the swimming pool to test and speed up the learning.

The fifth advantage of this creation is that the private swimming instructor can provide more delicate and more standard teaching. When the students are familiar with the action, they can go to the swimming pool to verify the swimming skills. Many swimming decomposition actions do not need to go to the swimming pool to do it, such as simple strokes. Hand exercises can also be done on land. Simple ventilation exercises can replace the water in the pool with washbasin water. The kicking can be practiced on the mat. It is an important swimming foundation to familiarize yourself with the full swimming rhythm on land.

The sixth advantage of this creation is the use of this creation on land. There is no drowning safety issue, and girls will not stop practicing due to the physiological period.

At present, when the teachers in the school are teaching swimming, there are also teaching exercises on the side of the pool. It can be seen that the teaching of on-the-spot swimming is feasible. It is only after standing and teaching that it is impossible to expose the whole picture of swimming skills in the water, and some teachers will lie on the table to demonstrate. Only the table can not make a complete swimming movement, and it is not suitable for students to study at the table. In order to increase the rate of swimming as soon as possible, and thus reduce the ratio of drowning, this creation It provides a complete set of swimming movements, guiding the user's hands, feet and the path that the ventilation should take. It can make up for the shortage of swimming teachers, and it is very helpful for students to learn to breathe swimming. It is important, novel and efficient. Simple, economical and practical features can be said to be a good swimming aid. In fact, swimming skills are very subjective. Each coach may have his own swimming and teaching methods. The creation is to provide a platform to replace the buoyancy of the pool. In the absence of a pool, coaches can still use their unique swimming skills to teach.
