• DE-GM 17 70 532 shows a swimming board that has a substantial body with at least two handles and a cutout for the head or chin of the swimmer.
• the swimming board is used for easy learning to swim, rescuing drowning people and as an aid to rescuing shipwrecked people.
• DE 43 33 341 A1 discloses a buoyancy aid which has buoyancy elements which are connected in numerous variants to a carrier element.
• the buoyancy aid is attached by a belt in the waist area of the swimmer.
• CONFIRMATION COPY Floating systems are also known, in particular in the form of a two-part swimming training aid with a flat base element and a resistance element which can be inserted vertically therein.
• the flat base element is essentially rectangular with a trapezoidal shape provided in the upper area. The corners are rounded. An elongated rectangular slot is provided in the upper trapezoidal extension. In the lower area of the flat base element, round openings are provided at a distance from the outer edge of the base element. On the one hand, feet can be inserted through these round openings. On the other hand, the front limbs of the hands can engage in it, with the heel of the hand holding onto the outer edge of the flat basic element.
• the flat resistance element has a central area which fits exactly into the elongated rectangular slot of the flat base element. Outside this central area, the resistance element protrudes on one side.
• the resistance element forms an essentially rectangular area with rounded corners and two round openings arranged symmetrically to one another in the area of this area.
• the other partial area of the resistance element which is adjacent to the area engaging in the flat slot is provided with recesses on the inside which are dimensioned such that ankles are accommodated therein.
• the recess is delimited on the outer side of the resistance element by elongated, hammer-like cantilevered end regions which describe a rounding with a flat edge.
• the resistance element forms a water resistance when inserted into the slot within the base element, this resistance element being able to perform a tilting movement due to the countercurrent water within the rectangular slot.
• the invention has for its object to provide a swimming and / or gymnastics system according to the preamble of claim 1, which is very easy to attack with your hands and can be held and with very little material very versatile for swimming exercises and gymnastic exercises in water, but can also be used on land.
• a swimming and / or gymnastics system according to the preamble of claim 1 in that additional elements have a water resistance-generating element which can be engaged in at least one central opening of the basic element and which encompasses the basic element at its outer edges and an elongated element Openings of the base element are engaging grip element.
• the swimming boards of the prior art are hardly suitable for swimming exercises in the supine position, since it is very difficult to intervene with these hands from below with the hands. It is therefore very difficult to hold the swimming boards in the supine position, since the swimming boards generally show the tendency to slip away from the engaging hands. This is particularly due to the fact that the swimming boards of the prior art, if they have any openings at all, show such a distance from the outer edges of the swimming boards that the attacking hands rest with the knuckles on the edges of the openings. With longer training this can be too lead to painful digging. This is precisely avoided in the boards according to the invention.
• elongated openings are particularly preferably provided in the region of the outer edges of the basic element.
• the elongated openings preferably have a curvature which corresponds to the curvature of the hand of the engaging hands.
• the engaging hands find particularly good hold in these openings.
• the additional element generating a water resistance is also advantageously attached to the flat base element such that even with greater water resistance, for example in the case of a fast-swimming user, it can only exert a slight tilting movement compared to the flat base element, in particular by a few centimeters in the lowest area, e.g. of a maximum of 3 cm.
• This is advantageously done in that this element which generates a water resistance acts twice on the flat base element.
• it engages in a central opening of the flat base element. This can be arranged anywhere in the region of the center line of the base element, in particular in the middle thereof. This is particularly preferably done by means of a projection in the middle of the additional element.
• the two adjoining elements encompassing the base element on its outer edges are preferably hook-shaped in such a way that they point towards the projection nose with their outer extensions, the hook-shaped outer extensions resting on the upper side of the flat base element.
• This additional element therefore particularly preferably consists of an elastically bendable but at the same time firm material.
• the projection nose is first inserted into the central opening of the flat base element, then the two hook-shaped elements are placed around the outer edges of the base element. These then clamp the flat basic element between themselves and the projection nose.
• the outer edges in the region of elongated openings of the flat base element with an inner arch or outer arch in the region of a central opening or two openings and with an outer arch in the region of two symmetrically arranged elongated openings on the opposite are particularly preferred Side of the middle or the two similar or correspondingly arranged opening provided.
• the flat basic element can be provided for gymnastics purposes but also for swimming exercises round or polygonal, for example hexagonal or octagonal.
• the elongated openings are each provided in the area of the outer edge of the base element.
• each mirror-symmetrically arranged elongated openings in the region of the longitudinal edges and / or in the region of the corners of the base element may be provided, for example two or four people can then intervene in these elongated openings for gymnastic purposes.
• These elongated openings are then preferably provided in the region of the long sides of an elongated, essentially rectangular, flat base element provided with inner arches and / or outer arches on the narrow or short sides.
• the flat base element and also the additional element which generates a water resistance are particularly preferably composed of layers.
• a hard polyethylene or a light foam foam is particularly preferred as the material.
• fabric for example one under the brand Piastazote ® from Zotefoams Ltd. offered lightweight foam used.
• the plate-shaped handle element is particularly preferably made of a harder, elastic, shatterproof material, for example a plastic. It particularly preferably shows a bummerang-like shape of its plate part, which is provided with openings, in particular four bores. Handles are provided to engage in these openings. These protrude with their loops or formed as cords on the top of the plate part and are attached to its underside.
• the handles are preferably formed as flexible loops or cords, which are at least partially surrounded by resistant tubular envelope elements. The robust cover elements enable better grip and a firmer grip in these handles. This also reduces wear on the cords.
• a further additional element in the form of a rod-shaped element is particularly preferably provided. This is designed in terms of its diameter or the central opening of the base element is dimensioned so that the rod-shaped element fits into the central opening. Due to the suitable choice of material for the rod-shaped element, it holds firmly in place within the opening. For example, by plugging two basic elements onto one end of the rod-shaped element, a system can be created that the practitioner can hold on to with his hands or support on his arms. Exercises can be performed particularly advantageously in the back or chest position.
• the devices from the state of the art are mainly intended either for learning to swim in the simplest form or for saving drowning people and shipwrecked people. Despite the simple and easy to understand assembly options of the devices according to the invention, their field of application goes far beyond.
