Description

[Detailed description of the invention] This invention relates to a swimming training device for the purpose of indoor swimming basic training, strengthening physical strength, and mastering swimming techniques.

As is well known, even though swimming is generally called swimming, there are many different swimming styles, and the usual competitive swimming events include crawl, breaststroke,
Typical examples include butterfly and backstroke.
Each type of bending and stretching movement in each part of the body has its own characteristics, so mastering and promoting these characteristics will contribute to improving the strength of the relevant event, and this idea is intended as a basic training device to achieve this in water. The aim is to achieve this goal through training indoors on the floor, and to provide a training device for breaststroke as an event.

Next, an embodiment of the present invention will be explained with reference to the drawings.

1 is the main body of the vessel of appropriate height, and its length should be much longer than the person's height. Top plate 2 of the main body 1
On the surface, a series of guides 3, 3 are provided on both sides. Reference numeral 4 denotes a running plate shorter than the user's height, which is installed on the top of the base plate 2, and is movable forward and backward via rollers 5, which are fixed to the bottom of the base plate and whose spacing is slightly smaller than that between the guides 3 and 3 on the base plate. . 6 is the running board 4
The upper body is tilted low to the rear with a fixed upper body plate. An assembly plate 7 is fixed in the width direction in front of the lowering plate 6, and rotary plates 8, 8, which can freely rotate outward, are hinged to both sides of the plate. 8a is a handle portion of the rotating plate 8. Reference numeral 9 denotes connecting rods protruding from both sides of the running plate 4 in front, and a frame rod 10 is fixed to the tip of the connecting rod in a direction parallel to the assembly plate 7. Rotating plates 8 on the same side as both ends of the frame rod 10
An elastic member (for example, a rubber belt, a rubber tube, etc., the same applies hereinafter) 11 of suitable strength is attached to the handle portion 8a.
is interposed to constantly pull the rotating plate 8 in the direction of the frame. Reference numeral 12 denotes an elastic member of a predetermined length, one end of which is fixed to the intermediate portions of both sides of the running plate 4, and the other end of which is connected to an appropriate position on the floor near the rear of the main body 1 of the main body 1 or on the lower part of the wall. 13 indicates a wall.

In this case, the use condition of the above-mentioned structure is described.The rear part of the main body 1 of the device is attached to the wall 13, the traveling plate 4 is set in a retracted position, and the elastic member 12 is set to an extent that an appropriate amount of slack is generated. . As shown in Fig. 3, the practitioner places the upper body in a prone position on the prone board 6, with the lower body bent as much as possible with the legs spread apart, so-called frog legs, with both feet pressed against the wall, and with both hands on the rotating board 8. By strongly grasping the gripping part 8a of the hand and bending the elbow joint deeply, strong resistance is applied to the elastic member 11 interposed between the handle 8a and the support rod 10. In other words, the palm, forearm, Elbow, upper arm, shoulder,
It stimulates muscle strength in the deltoid and lateral chest regions. If you kick the wall 13 strongly with both feet from this position, the running board 4 will move to the rollers 5 while keeping the upper body on the face down board 6 without receiving any resistance from the elastic member 12 which has been given an appropriate amount of slack in advance. The forward movement of the traveling plate 4 is restricted from the position where resistance is applied to the elastic member 12, so by strengthening the initial kick with both feet, the elasticity of the member is increased. It becomes possible to overcome the resistance and advance the traveling plate 4 further forward.
Rotating plate 8 grasped in both hands in synchronization with this forward movement
are made to open outward. This movement is caused by the repulsive force of the connected elastic member 11, so the resistance of the muscular forces acting on both arms is not strong.

As mentioned above, the greater the forward distance of the running plate 4, the greater the repulsive force of the elastic member 12, so the backward movement is also active, and during this backward movement, the rotating plate 8 is retracted, causing the bending of both arms. As the muscle strength stimulation associated with this is repeated, the lower body simultaneously shifts to a split-legged flexion position, and when both feet come into contact with the wall 13, the leg lifting action is performed again, and these repeated movements lead to basic breaststroke training. This is what we provide. When the running board 4 moves forward by kicking with both feet, if the forces of both feet are not equal, it naturally prevents the running board from going straight and causes it to move to the right or left, but since the guides 3 are protruded on both sides of the base board 2, there is a risk of falling. This does not occur, and the provision of play by setting the rollers 5 at a smaller interval than the interval between the guides 3, 3 is also significant in helping the practitioner master the balance between both feet.

As is clear from the above, the present proposal is to provide a running plate that can move forward and backward on the top plate of the main body, and to restrict the running movement to a certain extent using an elastic member, and to use a rotating plate provided on the running plate. By applying an appropriate amount of resistance to the rotational movement through an elastic member, the practitioner who lies down on the running board can spread his legs apart as a lower body exercise to move the running board forward.
Bending/stretching, stiff movements, and rotating plates can be grasped, and the muscle strength associated with bending mainly in both arms can be practiced repeatedly and continuously based on the mutual relationship, and physical strength can be improved at the same time as basic training and swimming technique mastery. It can be used to strengthen the body, and it is unique in that it can be carried out indoors on the floor, and its practical value as a swimming practice tool is highly praised.
