Abstract

A paddle of the training oar comprises the rim, the device for attaching the rim to the pole of the oar, and the cover of the paddle. The shape of the rim is adapted for rowing. The device for attaching the rim to the pole is designed as the holder with the fixing screws. The cover of the paddle represents a pair of the flaps made from the elastic material and mounted longitudinally on the hinges on the axis joining the ends of the rim allowing for changing the angle of the inclination of each flap relative to the plane of the rim.

Description

The intended invention relates to sports, in particular to devices for training oarsmen and methods of implementing their physical efforts to ensure the movement of watercraft.

A well-known loading mechanism for rower training, which has a hydraulic cylinder, the cavity of which has a non-return valve installed in the piston from the side of the rod, hinged to the oar, and a means of imitating acceleration of the boat in the form of a mechanism of water-filled channels / auto. St. USSR, Mo1643027, Ab63869/06, By Me15, 19917,

The disadvantage of this device and its mechanism is that it is a very complex structural complex of equipment for a room equipped with water supply, and the manufacture of special hydraulic cylinders with a special arrangement of valves on their pistons is a very complex and long technological process, so not every rowing athlete , and even more so an amateur, will have the opportunity to train in such a complex structure.

A well-known device for training rowers in a pool, which has two side channels connected to each other by a middle channel, on the water of which there is a watercraft with a movable seat connected to an oar installed behind it in the middle channel in the form of a lumbar hinged plate. / author St. USSR,

The disadvantage of this device is also its structural complexity, although the water flow in its channels to simulate the movement of watercraft does not require any mechanism, but is created by the rower himself, performing rowing movements with the side oars and the rear oar-fin.

A known device for training oarsmen, which has a horizontal guide for moving the oar blade along the magnetic block, interacting with a ferromagnetic plate fixed on the oar blade /auto. St. USSR Mo1174048, A63B69/06, By Me22, 19917,

The disadvantage of this device is that it is possible to adaptively model the movements of the oar blade in the water with the help of this device only with a big assumption, because the movements are possible only along the direction, and this never happens in real rowing.

In addition, the strength of the magnetic power lines also needs to be adjusted along the wiring of the oar and creating its variable load, which requires certain mechanisms and devices. This also limits the possibilities of using this device in the practice of training rowers.

A known loading unit of a rowers training device, which has a similar magnetic unit with a guide for the oar blade, although its magnets are adjustable in size and interact with the alternating load on the ferromagnetically equipped oar blade, but this did not provide an opportunity to provide a sufficiently adequate modeling of this device for a correspondingly effective preparation oarsmen / author St. Me1650170,

A well-known paddle of a device for training rowers-kayakers, which has a handle and a sharpened shaped tip for support and repulsion from ice or the earth's surface /author. St. Me1163870, Ab3869/08, By Mo24, 1985/.

This analogue is closer to the proposed one, but it has an important drawback - instead of a blade, its oar has a hook, and this excludes any possibility of using this device for imitating and modeling rowing on water - both for rowers and kayakers, and for all other athletes and amateurs.

The closest in essence is a device for rowing, which imitates a watercraft, but is made on wheels with the possibility of movement on the surface of the earth and at the same time its oars are equipped with hinged air blades attached to them, each of which is made in the form of a rim with a covering of strong fabric stretched over it / author St.

USSR Me1694169, AEZV6B9/06, By Me44, 19917,

The disadvantage of the prototype is that the blades of such a device must be made of large sizes, and therefore this simulator of a watercraft and especially its aeroblades must be of significant dimensions, and therefore it can be used only in open areas, although the design of the prototype is very original, but it is not enough for training oarsmen effective due to the fact that other aerodynamic laws operate in the air, which are significantly different from those in the water, and this tool will not work on the water. Therefore, this "butterfly" will not float and it is impossible to train rowers on the water with its help in any type of rowing.

The invention is based on the task, taking into account all the positive qualities of the prototype - a device for rowing, and its shortcomings, to create such a device for training rowers, which would be more adapted for use on water, to better imitate and model the conditions of their moving activity in a real environment. For this, attention was paid primarily to the oars of watercraft, namely to their blades, which directly provide them with motion. | therefore, for the effective performance of this function and preparation for the rowing action of specialists, a new instructional oar blade is proposed, which can be used during training, and academicians, and kayakers, and canoeists when using the appropriate oar handles. To change the training load, without which a simulator is not a simulator, the proposed paddle blade must be equipped with a suitable device. This device is made in the form of holes in the plane of the rim of the oar blade, which regulate the passage of water flow through it.

The problem is solved by the fact that the blade of the oar, which has a rim with a means of fixing it to the oar handle, a rim made of a coating on it and a means of attaching the rim to the oar handle and corresponding to the shape of the coating, according to the intended invention, is fixed on the oar handle, the rim is made in the form adapted to rowing on water, and the means of fixing it to the handle of the oar is in the form of a holder-clamp with fixing screws, while the rim covering is made in the form of flaps of elastic material located in the rim, hinged and longitudinally installed on the connecting limb of the rim of the axis with the possibility of changing and fixing the angle of lateral inclination of each of them relative to the plane of the rim.

The technical result, achieved thanks to the use of all the distinguishing features of the proposed device, is that such an oar blade has been created that can be used for the training of rowing sports specialists in all its types - academic rowing, kayak rowing and canoe rowing and with a high level of modeling and adaptations to their characteristics. At the same time, this blade provides a wide range of changes in the physical load on the rower's muscles, which increases the efficiency of his training. The main thing is that it gives an opportunity to master rowing skills without going out into an open body of water, which is very important for amateurs, especially at the first stage of forming their rowing skills and abilities.

The essence of what is proposed is explained by the drawing, where Fig. 1 shows the general view of the blade of an exerciser in axonometry; in Fig. 2 - the same, top view; in Fig. 3 - the same, side view; in Fig. 4 - also the same, a view from the back / from the end / when the penetration through the blade of water is completely blocked; in Fig. 5 - the same, with an average level of water penetration; in Fig. 6 - the same, with a slight partial passage of water; in Fig. 7 - the unit of installation of the flaps of the overlap of the blade; in Fig. 8 - the same, side view; in Fig. 9 - the same, top view.

In particular, the blade of the exerciser paddle has a rim 1, bent in the shape of the blade of the paddle of the type of rowing sport to which it belongs, and made of a strong elastic material. The free ends of the rim are attached to the holder 2, made in the form of a hug for placing and fixing the end of the holder Z oar, with screws 4, for which threaded holes 5 are provided. The opposite ends of the rim 1 are connected by axis 6, which is the base of the hinge. This hinge connects, as in a door hinge, two leaves 8, which together cover the clearance of the rim 1. In the middle of the axis 6, where the hinges 9 connect to each other, a node for installing the leaves 8 is made in the form of a screw 10, screwed into the threaded hole of the axis 6 and passed through its unthreaded part through the half-holes made on the abutting surfaces of the hinges 9. This is shown in Fig. 4, 5, 6 and especially - 7, 8, 9. The curvature of the flaps 8 along their outer edges is shown in Fig. 1 and dotted in Fig. 3, 4, 5. The inner edges of these flaps are directed and planted with their loops 9 on their straight axis b /fig. 1, 2, 3/.

Use the paddle of the exerciser in this way. They put it on the end of the handle Z oar with the holder 2 and fasten the rim 1 with screws 4. They tilt the flaps 8 to the lowest position, previously unscrewing the screw 10 and freeing their hinge 9 from fixing. Then the flaps are fixed again by screwing in the screw 10, which enters the half-holes on its sides 11 adjacent loops 9, which prevents their rotation on the axis 6 of one from the other /fig. b, 7, 8, 9/. In this state, the blade is used in the initial stage of training and training. After completing the creation of the ability to own an oar with this paddle, move on to training and consolidating rowing skills. To gradually increase the load on the oar, the flaps 8 are gradually rotated and fixed at sharper angles relative to the plane of the blade-rim 1 /fig. 4, 5, 6/, for which the same screw 10 is used.

The rower will receive the greatest load when the flaps take a horizontal position in the rim 1 /fig. 1, 2, 4/. But at the same time, gaps remain between the rim and the flaps, through which the blade will pass water, and the current of water in these gaps will ensure the stability of the movement of the oar, exclude the possibility of "walking" it in height during the wiring process, which will adequately simulate the process of rowing. Such stabilization is especially necessary at the beginning of the development of rowing skills, and this is ensured at more obtuse angles, when lowering and fixing the flaps 8 (Fig. 5) and especially (Fig. 6). In this case, stabilization is also ensured by the arrow-shaped arrangement of these beams - by bringing them closer to each other /fig.b/.

In this way, the conditions of real rowing are simulated and modulated when the training is carried out on stagnant water, which makes it possible to carry out the rowing training process continuously, even when there is no possibility to use other simulators, and when there is a lack of specialized rowing pools.

The technical and practical consumer advantage of the proposed over the prototype is that the creation of such an oar blade, which can replace a specialized rower’s simulator, has made it possible to simulate and model rowing processes more realistically, which provides higher training efficiency for rowers of various types of sports and non-sports rowing and in the necessary conditions to prevent the use of complex high-cost pools.

We hope that such training paddles will be useful to all rowing athletes and it will give them and amateurs the opportunity to acquire real rowing skills in any conditions, so that there would be some kind of water container for the oar.
