Definitions

  • the invention relates to a sports equipment for use in the water, a set of sports equipment and the use of the sports equipment for running water sports with the help of hands.
  • oars or paddles are used to move boats in the water.
  • Rudder and paddle have for this purpose a long, straight handle, at the end of a flat component is attached, and at the other end there is a handle.
  • the stem between the handle and rudder blade is movably attached to the boat, so that as the handle is pulled towards the body, the rudder blade is moved away from the body by the water. The sportsman thus moves backwards with the boat.
  • a paddle also has a long handle, at the end of which a blade is mounted which has a handle at the end of the paddle remote from the blade. Paddles are not attached to the boat during operation.
  • the sheet moved for movement through the water is attached to one end of the stem while the handle is at the other end or between two leaves.
  • a water sports equipment, in which the leaves are attached after the handles on the stem, is in DE 36 28 637 A1 described. To move the leverage is used.
  • Object of the present invention was to provide an alternative sports equipment available with the gymnastic power endurance sport can be operated in the water. This object is achieved by the present invention.
  • the invention relates to a sports equipment with a blade, a handle and a handle, wherein the handle is located between two brackets on the stem, with which the stem is attached to the sheet.
  • Another object of the invention is a sports equipment, in which two sports equipment, each having a leaf, a handle and a handle, in which the handles are each between two holders on the stem, with which the stem is attached to the leaf, with each other a connector are connected.
  • a component As a sheet in the context of the present invention, a component is referred to, which can be pulled with a suitable training of the musculature force against resistance through water. For this purpose, it usually has a c w value of between 1.0 and 1.5, preferably between 1.15 and 1.4. Although completely flat sheets (c w value of about 1.0-1.1) are suitable with respect to the direction of movement. However, more suitable blades have an area that has a space open against the direction of movement. An example of such a sheet is a hemisphere or half shell open against the direction of movement. If such a sheet is pulled through the water with the open side, it feels more stable.
  • mussel shells have reshaped leaves of such a shape.
  • the sheet is preferably impervious to water or has a sufficiently large, non-perforated surface. A sufficient water resistance will be present when the sportsman has to make an effort to move the sports equipment perpendicular to the handle through the water.
  • the c w value of the sheet can be brought into the range in which it is useful for the invention by various constructive measures.
  • One of these factors is the angle of attack against the direction of movement. This can be influenced by the attachment of the handle and the angle of the stem to the sheet.
  • the angle of attack is within the meaning of the invention between 75 and 90 degrees, preferably between 85 and 90 degrees.
  • Another factor is the surface of the directed against the direction of movement surface of the sheet.
  • it can have an angle of more than 80 degrees of angle, preferably between 85 and 90 degrees of angle, with respect to the direction of movement in the water.
  • the same sports equipment is suitable for training without constructive changes for both stronger and weaker persons, or you can exercise the same movement pattern with much or little force.
  • the components of the blade used to generate the water resistance are preferably formed from a lightweight material. It may be a uniform material, such as plastic, but also a composite, such as reinforced plastic or carbon. Polypropylene is the material of choice for reasons of cost and flexibility, which does not mean, however, that other materials such as fiberglass or even carbon for higher-quality sheets (or the entire sports equipment) are excluded.
  • the sheet is preferably made with substantially uniform wall thickness.
  • the wall thickness of the sheet according to the invention is usually for the majority of its surface depending on the material between 1.2 mm and 1.5 mm.
  • the preferred thickness of the sheet in the area is 1.3 mm, and in the area of the holders 5 mm.
  • the flexibility of the sheet, even at different locations of the sheet can be adjusted. It has been found that it is pleasant for the water sports with the invention for the athlete, if the sheet is not completely rigid. A deflection at the edge of up to 10 cm, preferably between 1.2 cm and 1.5 cm, when moving through the water has proved to be gentle on the joints, even under extremely high load, since the force development can be gentle.
  • plastic has proven to be particularly suitable.
  • the size of the cross-sectional area through which the water resistance is generated also has an influence on the force which the athlete has to apply in order to move the sports equipment through the water.
  • this area does not mean the area of the surface of the sheet, but the area of the projection of the sheet onto the area perpendicular to the direction of movement.
  • this is not the (half) sphere inside surface, but the area of the cross section through the (imaginary) sphere.
  • the area of the sheet effective for water resistance can thus have an area of between 100 and 2000 cm 2 , with smaller area sports equipment requiring less power, making it more suitable for beginners or children, while larger area equipment is used for training experienced people strong muscles are better suited. For adults with average strength, an area of between 600 and 1000 cm 2 is suitable.
  • the blade is attached to the handle with two brackets.
  • This handle has a handle through which the sports equipment can be grasped and moved through the water.
  • the stem extends between the two holders of the sheet. It can therefore have any form that ensures this function. In its simplest form, it may therefore be a rod with a round cross-section. Preferably, it is tubular.
  • the handle is so long that it can be held on the one hand by the brackets, and on the other hand that he can pick up or form the handle. The minimum length is therefore determined by the distance of the brackets from each other. This, in turn, is dictated by the fact that the handle lies between the brackets and is thus dictated by the width of the athlete's hand. The maximum length is given by the dimensions of the blade.
  • the stem is not or not substantially permanently protrude beyond the cross-sectional area of the sheet, because this could otherwise lead to injury from the protruding part.
  • the stalk therefore usually has a length of between 20 cm and 30 cm; 25 cm are preferred.
  • the diameter of the handle tube is preferably between 15 mm and 40 mm, more preferably between 20 mm and 30 mm. If you use a tube with a diameter of 24 mm, you can use a standard bicycle handlebar handle as a handle.
  • the handle is made of a material that is strong enough to hold the handle in a fixed position relative to the blade.
  • metals or plastics are suitable. If the sports equipment is to be particularly light, light metals have proved to be preferred. In addition, it must not corrode.
  • the handle can also be made of plastic, in particular of the plastic, from which the sheet is made. This also facilitates the production, since then the sports equipment can be produced in an injection molding step.
  • the handle may be part of the stem or a moored to the stem component, which includes the stem largely or completely, so that you can largely or completely surround the stem by hand.
  • the size of the hand therefore essentially determines the circumference of the handle.
  • the circumference is thus preferably between 8 cm and 20 cm.
  • the stem is a long component with a round cross-section, which is so large that it can be easily grasped and held by hand.
  • the diameter is then between 2 cm and 6 cm, preferably between 2.5 cm and 4 cm, with a small diameter for smaller hands, as in children, is advantageous.
  • a separately mounted handle is then no longer necessary, since a part of the handle serves as a handle.
  • this has the disadvantage that it is more difficult to grasp and hold the handle without the hand slipping on the handle during the exercises.
  • Another embodiment is characterized in that the handle and handle are made of the same material, and the handle is formed from the material of the handle, such as to ensure better tangibility of the handle.
  • This embodiment is particularly easy to produce if the sports equipment is made of plastic, since the device can then be produced by injection molding.
  • the plastic can be ergonomically shaped in the region of the handle, so that it is designed to be handy.
  • the handle on the stem is formed separately.
  • the shape is designed so that you can hold it well with your hand. This may have about the shape and size of a conventional bicycle handlebar handle made of soft plastic. So that the hand can not slip in the direction of the brackets, spacers can be provided on the sides of the handle.
  • the handle is a cylindrical piece of rubber, which is pushed in the installation of the handle made of aluminum tube to the desired location.
  • the material of the handle is chosen depending on the desired design. Particularly suitable are soft plastics that are easy to work with, are skin-friendly and secure to the touch.
  • the handle can be located anywhere between the brackets.
  • the handle is fixed on the handle, so that the sports equipment is always firmly gripped in the same place.
  • This is preferably chosen so that the force distributed by the hand as evenly as possible on the sports equipment so that the effective surface against the water resistance is as perpendicular to the direction of movement of the sports equipment.
  • This point is preferably placed in the symmetrical shaped sheet in the thumb nearer, front third of the stem, provided that the holders are located respectively at the outer ends of the sheet. If the water resistance on one side of the blade is increased, the handle will usefully continue to be shifted to this side. This serves a more even training.
  • brackets connect the blade to the handle. This connection can be permanent, but also temporary. During training, secure attachment of the blade to the stem should be ensured. If the sports equipment to be dismantled, brackets can be selected in which the stem or the sheet can be removed from the holder, or in which the brackets can be solved.
  • An embodiment with permanent connection results when the sports equipment is to be made of a single material, such as plastic, by injection molding.
  • the support may be permanently attached to the blade or handle and connected to the handle or blade to complete or provide the sports device.
  • the compound can be done by conventional methods. For this purpose, insertion, screwing, clamping, snapping or a combination of one or more of these methods are suitable.
  • the brackets are located on the side of the sheet or the sports equipment on which the stem is located and which lies on the side of the direction of movement of the device.
  • the area of the blade encloses the space around the handle at between 5% and 75%.
  • the brackets have a receptacle for the stem, in which it is then secured by screws.
  • the brackets are so far from each other attached to the sheet, that on the stem is still room for the handle.
  • both brackets may be in the form of openings in the blade.
  • the first holder is part of the sheet on the side of the sports equipment lying on the side of the direction of movement.
  • a component is provided at the one end of the blade, which projects in the direction of movement on the stem and has a receptacle for the stem, for example a round opening with the outer shape of the stem.
  • the stem is screwed into the receptacle on the one hand and clamped on the other side.
  • the second holder is formed by a hole in the sheet into which the stem is received, for example a round hole with the outer shape of the stem extending from the inside of the sheet to the outside through which the stem extends from the inside to the outside can.
  • Fasteners such as screws or clamps, may then be provided on the inside or outside of the blade. Again, the two brackets are so far away from each other on the sheet that between them room for the handle with the handle.
  • the brackets and the handle also serve to hold the handle so far away from the blade that the hand does not come into direct contact with the blade when grasping the sports device on the handle and especially during the exercises. This is ensured if the distance of the handle from the blade is more than 5 cm.
  • the distance is between 5.5 and 11 cm.
  • the sheet is formed from a strongly rounded, rectangular, curved plastic sheet with a width of 20 cm and a length of about 30 cm, but not more than 50 cm.
  • the edges of the plate are bent in the direction of the handle, so that a hollow interior forms, wherein the edge on one side protrudes beyond the stem, so that the stem protrudes through an opening in the plate from the interior to the outside.
  • the sports device according to the invention can be produced by conventional methods. If the sports equipment is entirely made of plastic, it can be injection molded from a thermoplastic such as PP and PE. The sheet including the brackets is preferred in Injection molding process made of PP. If individual components are to be made of other plastics, for example softer materials, such as the handle, the sports device can be produced in a two-component injection molding process. If the sports equipment is made of different materials, the individual components can be manufactured separately and then assembled. This is the case when individual components, such as the stem, should be made of metals, others made of plastic.
  • the sports device according to the invention can be used to operate water sports.
  • the athlete goes into the water, standing or free to move, takes the sports equipment with one hand firmly on the handle and moves the sports equipment through the water.
  • the movement can be both horizontal and vertical.
  • the effort and thus the training effect can be adjusted so that the sports equipment is gripped on the handle so that different angles of attack of the sheet to the direction of movement arise.
  • the effort is highest when the c w value reaches the highest value. This is usually the case when the effective area of the blade with respect to a particular direction of movement is greatest. You can do the same exercises with a lot or with little effort.
  • An example of an exercise with the sports equipment according to the invention is grasping the handgrip with the arm outstretched so that the interior of the blade points towards the athlete, moving the sports equipment towards the athlete by tensing the arm musculature and then returning the sports equipment to the starting position.
  • Another exercise is grasping the sports equipment by the hand with the arm extended forward so that the interior of the sports equipment is facing down, moving the outstretched arm down with the sports equipment, and returning the sports equipment to the home position.
  • the muscles are not only trained in bending the arm muscles, but also during stretching of the arm muscles during the return to the starting position.
  • the movement in the water also ensures that balancing movements throughout the body are required so that the body remains in place and does not fall forward or backward.
  • the sports equipment according to the invention therefore ensures a gentle load on a variety of muscle groups by a gentle force development.
  • the sports equipment according to the invention can also be used for locomotion through the water.
  • One way to do this is swimming in the familiar crawl style.
  • each hand takes one of the sports equipment according to the invention.
  • a sports equipment is guided through the air from back to front, while the other is pulled from front to back through the water.
  • the water resistance generated by the blade is translated into a movement of the athlete forward.
  • the use of the sports equipment according to the invention for swimming is not quite as easy as it seems, but skilled swimmers can learn the new techniques quickly.
  • the sheet of the invention preferably has a curved, oval, oblong shape.
  • the said sheet describes the shape of a blade, which has a central handle in the longitudinal direction.
  • the sports equipment according to the invention generally has a length of about 30 cm, a width of about 20 cm and at the lowest point a depth of about 12 cm to 15 cm.
  • the sports device according to the invention may contain other components. This can be a component that can be used to connect to another sports equipment. If the other sports device is another sports device according to the invention, the component is preferably a connecting piece, for example a connecting shaft, which can be attached to the second copy of the sports device.
  • this connecting stem mounts are either on the connecting stem or on one or both sports equipment available. Because of the rapid solubility clamping brackets are preferred. In one embodiment, one of the brackets of each of the two sports equipment used to attach the stem to the blade is also used to secure the connecting stem.
  • the shape of the connector or connecting stem is chosen so that the two connected sports equipment can be detected in each case with one hand on each handle and he firmly connects the two individual sports equipment, preferably on their stems with each other.
  • the connecting handle is so long that the two sports equipment have a training sufficient distance from each other.
  • the length of the connecting post is variable, so that different exercises can be trained.
  • the connecting rod is so long that the connecting rod can be completely sunk in the sports equipment according to the invention, so that nothing protrudes. This avoids the Risk of injury.

For example, the first sports device can be moved down while the second is moved upwards.
  • This set may further include a connecting post for attaching the two sports equipment together. This may be contained loose in the set, but also be attached to one of the two sports equipment. This set can contain the individual sports equipment in a separate form as a set, but the individual sports equipment can already be connected to each other via the connector.
