Description

The invention relates to a swimming and / or gymnastics system that a flat Basic element with openings and further pluggable with these openings Has additional elements.

Swimming boards and swimming aids are known, for example from DE-PS 593 763, DE 43 33 941 A1, DE-GM 1 770 532 and prospectus of Volley Sportartikel GmbH, Ispo 1989, pages 18 to 20. DE-PS 593 763 discloses an auxiliary device for independently learning to swim, in which a shaped plate at the rear end has a semicircular recess to support the chin of the swimmer and on the top has at least two handles, the arm length distance in the front direction are attached to the top of the plate.

From DE-GM 17 70 532 a swimming board emerges which is considerable Body with at least two handles and a cutout for the Head or chin of the swimmer. The swimming board serves that easy learning to swim, rescue drowning people and as an aid to rescue shipwrecked people.

DE 43 33 341 A1 discloses a buoyancy aid which has buoyancy elements, which are connected with a carrier element in numerous variants become. The buoyancy aid is fastened by a belt in the waist area of the Float attached.

These previously known swimming boards, swimming learning aids and rescue aids are only usable for their respective very narrow purpose.

Floating systems are also known, particularly in the form of two-piece swimming training aid with a flat base element and one vertically into this insertable resistance element.

The flat base element is essentially rectangular with in the upper area provided trapezoidal shape. The corners are rounded shaped. In the upper trapezoidal approach there is an elongated rectangular one Slot provided. In the lower area of the flat basic element there are round ones 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 on the outer edge of the flat base element hold tight. The flat resistance element has a central area, which exactly in the elongated rectangular slot of the flat base element fits. Outside of this central area there is a collar on one side the resistance element. It forms an essentially rectangular one Area with rounded corners and two symmetrical to each other arranged round openings in the area of this area. The one in the the flat slot engaging area adjacent other portion of the Resistance element is provided with recesses on the inside, which have such a dimension that ankles fit into it. The Recess is made on the outer side of the resistance element by, a Rounding with flat edge describing elongated, hammer-like cantilever End areas limited. The resistance element forms in insertion a water resistance in the slot within the basic element from, this resistance element due to the counterflow Water within the rectangular slot can.

Such swimming systems are somewhat more flexible than those initially mentioned discussed swimming aids, but still very limited and limited use.

A swimming and / or gymnastics system according to the preamble of claim 1 is known from US-5 643 154.

The invention has for its object a swimming and / or gymnastics system to create according to the preamble of claim 1, which is very good can be attacked with the hands and can be held and with little Material expenditure very versatile for swimming exercises and gymnastic Exercises in the water, but can also be used on land.

The task is carried out by a swimming and / or gymnastics system according to the Preamble of claim 1 solved in that additional elements a Water resistance generating, in at least one central opening of the Basic element engagingly shaped and the basic element at its outer edges clamping element and one in elongated openings of the basic element are engaging grip element. Further training of the Invention are defined in the subclaims.

This creates a swimming and gymnastics system by means of which numerous water aerobics exercises for one person and for several People can be carried out. It is particularly suitable for Swimming exercises in the chest and also on the back. During swimming exercises in the supine position, the back of the floating becomes very advantageous Person stretched, which is very well controlled, for example, by the swimming trainer can be.

The swimming boards of the prior art are hardly suitable for Swimming exercises in the supine position, because in these swimming boards only very much it is difficult to intervene with the hands from below. A hold on the swimming boards in the supine position is therefore very difficult because the swimming boards generally show the desire to engage Hands slip away. This is particularly due to the fact that the State-of-the-art swimming boards, if they have any openings at all have such a distance from the outer edges of the Swimming boards show that the attacking hands with the knuckles the edges of the openings. With longer training this can be too lead to painful digging. This is precisely what will be advantageous for the avoided boards according to the invention.

Namely, the flat basic elements according to the invention are particularly preferred elongated openings in the area of the outer edges of the base element intended. The elongated openings preferably have a Curvature that corresponds to the curvature of the hands that engage. The engaging hands find particularly good hold in these openings.

The additional element producing a water resistance also becomes advantageous attached to the flat base element so that even with greater water resistance, for example in the case of a fast-swimming user can only exert a slight tilting movement on the flat base element, in particular by a few centimeters in the lowest area, e.g. of maximum 3 cm. This is advantageously done in that this has a water resistance generating element attacks twice on the flat base element. On the one hand it engages in a central opening of the flat base element. This can arranged anywhere in the area of the center line of the base element be, especially in the middle. This is particularly preferably done by a projection in the middle of the additional element. Two symmetrical to each other arranged straight areas are stored on the underside of the flat Basic element. The two following, the basic element elements encompassing its outer edges are preferred hook-shaped so that they face the projection nose with their outer Extend extensions, the hook-shaped outer extensions on rest on the top of the flat base element.

This additional element therefore particularly preferably consists of an elastic bendable, but at the same time firm material. When attaching the additional element the cantilevered nose into the central opening is attached to the basic element of the flat base element, then the two hook-shaped Elements placed around the outer edges of the basic element.

These then clamp the flat basic element between themselves and the projection nose on.

To create a better hand grip are special prefers the outer edges in the area of elongated openings of the flat Basic element with an inner arch or outer arch in the area of a middle opening or two openings and with an outer arch in the area of two symmetrically arranged elongated openings on the opposite side of the middle or the two similar or corresponding arranged opening provided.

Instead of three elongated openings, five or more or only two aligned in a line in the middle, symmetrical to the central axis of the substantially elongated flat base member. In These two openings can then be used by a person with a hand intervention. The flat basic element can also be used for tumbling purposes Swimming exercises round or polygonal, for example hexagonal or octagonal be provided. The elongated openings are each in the area the outer edge of the base element.

Instead of these two elongated openings on the narrow outer edges but can also be multiples of two, e.g. B. four, each mirror-symmetrical to each other arranged elongated openings in the area of the longitudinal edges and / or be provided in the area of the corners of the base element. In these elongated openings can then, for example, two for tumbling purposes or intervene four people. These are preferably elongated openings then in the area of the long sides of an elongated, essentially rectangular, preferably with inner bends and / or outer bends on the narrow ones or short sides provided, flat base element.

The flat base element and also the one is particularly preferred Water resistance generating additional element made up of layers. As Material is particularly preferably a hard polyethylene or a light foam, for example one under the brand Plastazote® from Zotefoams Ltd. offered lightweight foam used.

The plate-shaped handle element is particularly preferably made of a harder one elastic unbreakable material, such as a plastic, manufactured. It particularly preferably shows a bummerang-like shape of its plate part, which is provided with openings, in particular four holes. In these Handles are provided to engage openings. These protrude with their loops or formed as cords on the top of the plate part and are attached to its underside. Preferably, the handles are considered flexible Loops or cords formed by tough tubular Envelope elements are at least partially surrounded. Due to the resistant Envelope elements is a better vulnerability and a firmer hold in these Handles possible. This also reduces wear on the cords.

A further additional element in the form of a rod is particularly preferred Element provided. This is done 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 a suitable choice of materials for the rod-shaped element, this holds non-slip within the opening firmly. For example, by plugging two basic elements onto each one end of the rod-shaped element can be created a system where the practitioner holds on to his hands or supports the arms can. Exercises in reverse or also can be particularly advantageous be carried out in the breast position.

The possibilities according to the invention lead to a swimming and / or Gymnastics system that is far superior to conventional swimming systems is. It offers interesting opportunities, for example for the swimming instructor, motivate his students by being given a variety of variety are, many different exercises with the same device in always again performed new variations and put together positions can be and still only the cost of a device is required are. In addition to the low cost, this is only necessary mention small storage space for these swimming systems. Would you like to with different devices from the prior art the same or at least some of the possible movement exercises as with the invention Implement device, so is a large number of devices and a corresponding given a large space requirement. For example, for a promotion the correspondingly reduced weight requirement also plays a role on ships.

The devices from the prior art are predominantly either for Swimming lemen thought in the simplest form or also to save drowning people and castaways. Despite the simple and easy for the user understandable assembly options of the devices according to the invention their field of application goes far beyond that.

Figure 13

2 shows a perspective view of the flat base element according to FIG. 1 with additional elements attached by way of example.

FIG. 1 shows a perspective view of a flat base element 10, and of an additional element 20 that creates a water resistance and a plate-shaped handle element 30 as additional elements to the base element. The flat base element is essentially rectangular. It has a central opening 11. The two longitudinal edges 15 are formed essentially parallel to one another. The two outer edges 16, 17 arranged transversely to these longitudinal edges form an inner arch on the one hand and an outer arch on the other. A central elongated opening 12 is provided in the area of the outer edge 16 with the inner arch. The central elongated opening 12 has a curvature which is curved in the opposite direction to the inner arc of the outer edge 16. In the area of the outer edge 17 with the outer arch, two further elongated openings 13, 14 are provided. These are provided with a curvature which follows the curvature of the outer curve. In this way, it is possible to intervene particularly securely in the openings 12, 13, 14.

The four outer corners 18, 19 are rounded. The two corners 18 the outer edge 16 with the inner arch have a smaller radius on as the corners 19 on the outer edge 17 with the outer arch.

In perspective view are also two additional elements for the flat Basic element 10 shown in Figure 1. The one additional element is that Water resistance generating additional element 20. This is essentially flat. On one side it has a cantilevered nose 21 arranged in the middle on. The left and right of this centrally arranged projection nose 21 are straight Areas 22 are provided. These two straight regions 22 are connected hook-shaped clamping elements 23 on both sides. With their outer dimensions they protrude towards the projection 21. On the cantilever nose 21 and the straight areas 22 opposite side the additional element 20 has a bent end 24. The bend extends thereby between the two hook-shaped clamping elements 23 this. The area between the straight lines can have a water resistance Form areas 22 and the curved end 24 of the additional element 20.

The additional element 20 generating a water resistance is thus on the flat base member 10 attached that the projection 21 in the central opening 11 of the base element engages and the two hook-shaped clamping elements 23 reach around the flat base element and between it itself and the straight areas 22 of the additional element 20. On corresponding flat base element 10 with added water resistance generating additional element 20 is illustrated in Figure 11.

Furthermore, a plate-shaped grip element 30 is shown in perspective in FIG shown additional element to the flat basic element. The plate-shaped Handle element has two handles, which through openings 32 of a plate part 33 guided and attached to the underside. The handles 31 can for example as loops 35 with enveloping elements 34 enveloping them be educated. The enveloping elements 34 are, for example, tubular sections, which are put over the loops 35. This will make the Loops, which otherwise have hardly any particular strength in their The shape stabilizes and is therefore easier to attack. Besides, they are protected against faster wear. A fastening of the loops 35 on the underside of the plate part 33 is done, for example, by knotting over washers to prevent them from slipping out through the openings 32 prevent.

Instead of loops 35 with enveloping elements 34, prefabricated ones can also be used Handles 31 made of other materials can be provided. Preferably there is namely the plate part 33 made of a relatively hard, at the same time elastic and unbreakable material, especially a plastic. The Envelope elements also consist, for example, of a plastic tube, which envelops the loops 35 formed from fibers.

The flat base element 10 and the additional element are particularly preferably 20 made of hard polyethylene or another lightweight foam, in particular as layered foam layers. This can, for example the layers also have different properties, especially elasticity in the middle and hardness on the outer surfaces.

FIG. 2 shows a perspective view of a second embodiment of a base element 10 according to the invention. Like the flat base element 10 according to FIG. 1, this base element has a central opening 41.

In contrast to the flat basic element according to FIG. 1, however, the with outer edges 46, 47 arranged between the longitudinal edges 45 Provide outer arches. In the area of these outer edges 46, 47 are respectively oblong openings 42, 43 are provided in the center. These are mirror symmetrical shaped to the central axis of the base element. The elongated openings are each provided with curvatures that correspond to the respective outer arc of the both outer edges 46, 47 follows.

Such a basic element 10 according to FIG. 2 is very well suited for water aerobics exercises, since it has engaged with both hands in the two openings 42, 43, the flat base element held in front of the body and for example can be pivoted to the left and to the right.

FIG. 3 shows a third embodiment of a basic element according to the invention. In this case, the flat base element 50 has a round shape and is composed of three layers 54. Similar to the base element 40, the base element 50 also has two elongated openings 52, 53, which are arranged symmetrically to the central opening 51 and to the center line formed thereby. The two elongated openings 52, 53 also have a curvature which at least partially follows the outer radius of the base element 50.

FIG. 4 shows a perspective view of a fourth embodiment of a basic element according to the invention. The base element 60 also has a central opening 61. The base element 60 is hexagonal in shape. Similar to the base element 50, it has two elongated openings 62, 63. These are formed parallel to the outer edges 66, 67 and mirror-symmetrically to an imaginary center line through the central opening 61. In this case, the elongated openings 62, 63 are formed as straight openings, each with rounded corners and without curvature. Of course, like the previously mentioned openings, for example the elongated openings 52, 53 according to FIG. 3, they could also have a curvature.

Instead of the hexagonal base element 60, any one can also be used other polygon or polygon can be formed, for example an octagon or Decagon. Such a polygon then more and more resembles the round basic element 50 according to FIG. 3. Even the shape of a triangle would be possible, whereby then the arrangement of three elongated openings makes sense for gymnastic Purposes or for swimming exercises.

FIG. 5 shows a plan view of a fifth embodiment of a basic element according to the invention. The base element 70 is essentially rectangular and in turn has a central opening 71. One outer edge 76 has an outer arch, the other edge 77 an inner arch, similar to what has already been described for the embodiment according to FIG. 1. In contrast to this embodiment, several people can even attack the basic element 70 according to the invention according to FIG. 5. For this purpose, namely five elongated openings 72, 73, 74 are provided in the area of the longitudinal edges 78 and the narrow outer edges 76, 77 of the base element 70. The elongated openings 72 and 73 in the region of the edges 76, 77 are each in turn provided with a curvature which enables better hand engagement. In contrast, the elongated openings 74 in the region of the longitudinal edges 78 are straight, since the longitudinal edges 78 also run straight.

On such a basic element 70, either five people with each only one hand or two people, each with two hands or one attack another person with just one hand. It can also be a so-called "Yo-yo gymnastics" are performed. Should be four people, each with two Attack hands on the base member 70 are preferably each Longitudinal edge 78 instead of the two openings provided four of them and in the area edge 77 two instead of one. Also as a swimming board for one person it proves to be advantageous since either in the openings 72 or laterally can be attacked at the openings 74 or with one hand at the openings 77 can. For gymnastics exercises you can also use your thumb or thumbs in the Opening 71 and with the fingers in the opening (s) 74 or vice versa become.

An embodiment of a basic element according to the invention, on which three people can attack with two hands each, is shown in a top view in FIG . The shape of the basic element essentially corresponds to that according to FIG. 5. In contrast to the basic element 70 according to FIG. 5, two elongated openings 75 are provided in the region of the edge 77 in the basic element according to FIG. The shape of the elongated openings 75 follows the inner arc of the edge 77.

Figure 7 shows a further embodiment of a basic element according to the invention in plan view. The base element 80, similar to the base element 40 according to FIG. 2, has two outer edges 86, 87 with respective outer arches. Instead of the only one elongated opening provided there per outer edge, two elongated openings are provided in the region according to FIG. 7 in the region of the outer edges 86, 87. In their curvature, they follow the curvature of the outer arches of the two outer edges 86, 87.

In the area of the central opening 81 of the base element 80 is parallel to the an elongated opening 84 in each of the two longitudinal edges 88 of the base element intended.

Just as on the base element 70 according to FIG Basic element 80 according to FIG. 7 either six people, each with only one Attack hand or three people with two hands or four people, where in the latter variant two people with two hands each and attack two people with only one hand on the base element. Use as a swimming board for one person, as described in FIG. 5, is possible, as is the use described there as a gymnastic element.

FIG. 8 shows a further embodiment of a basic element according to the invention in plan view. The basic element essentially represents a combination of the basic element 40 according to FIG. 2 and the basic element 80 according to FIG. 7. It has two outer edges 46, 47 with respective outer arches and two longitudinal edges 45 which are straight in shape. Elongated openings 44 are formed around the central opening 41, parallel to the two longitudinal edges 45.

The embodiment according to FIG. 8 is suitable, for example, for four people, who only attack the basic element with one hand or for two people, each attacking the corner. Of course the basic element can only be used by one person, just like the one in the Basic elements shown previous figures can be used.

FIG. 9 shows a perspective view of a further embodiment of the system according to the invention for swimming and / or gymnastics applications. In this embodiment, two basic elements 10 are connected to one another by a rod-shaped additional element 90. For this purpose, the rod-shaped element 90 is inserted through the central opening 11 of the respective base element and pushed so far through that a non-slip hold is guaranteed in this opening due to friction and clamping.

For the greatest possible friction of the outer surface of the rod-shaped additional element 90, which is in particular a round rod, and the surface of the To create the central opening 11 of the base member 10 is the rod-shaped Additional element preferably made of the same material as that Primitive. The additional element therefore consists, for example, of a Light foam, especially Plastazote ®.

With an arrangement as shown in Figure 9, swimming and / or Gym exercises in the water in the chest and supine position get supported. For this, the swimmer intervenes with his Hands on the rod-shaped additional element or he supports himself his arms or armpits on this additional element 90. The two Basic elements are preferably stored with their longitudinal edges on the Surface of the water or dip something into the water.

The diameters of the central openings of the respective basic element are preferably adapted to the diameter of the rod-shaped element 90. Becomes a known such rod-shaped element in the form of a round rod used, an adjustment is preferably made to its diameter.

Figure 10 shows a side view of an embodiment of the rod-shaped additional element. This has a substantially uniformly thick central region 91 and tapered end regions 92. The thicker central area 91 provides a better support surface for the back or chest. The tapered end regions preferably fit into the central openings of the basic elements. When the central area 91 is loaded, the basic elements are angled at an angle. The end regions 92 preferably protrude beyond the outer surface of the base elements and are tilted in the central openings when the base elements are angled. You hold on to them. The transition to the end regions 92 can also take place continuously, as indicated by dashed lines.

FIG. 11 shows a second embodiment of the grip element 30. This is angular in cross section. Two plate-shaped parts 36, 37 abut one another essentially at right angles (in the region of their outer longitudinal edges). The part 36 is provided with the handles 31 on its surface facing away from the part 37. These can be glued there, inserted into openings and fastened therein, or cast in there or otherwise incorporated in the manufacture of the top of part 36.

The part 37 serves to generate a water resistance. Instead of the element 20 or in addition to this can be a special difficulty factor can be achieved by providing the grip element 30 on the base element 10.

As can be seen better in FIG. 12, the handles 31 are in turn by the elongated openings 14 inserted through. On the underside of the basic element 10, the part 36 provided with the handles 31 is positioned. The Part 37 then protrudes from this surface and can in particular when swimming back, when the hands engage backwards in the handles 31 as Water resistance generating element can be used.

The shape of handles 31 and handle element 30 can be chosen freely. Also the angle between part 36 and 37 can be made dependent on that desired resistance to be generated in each case.

In Figure 12, the central opening is not as in the previous embodiments in the middle of the basic element, but in the area of the center line (in Longitudinal direction of the basic element), but arranged off-center. Instead of of grip element 30 (or in addition to this) could be the resistance element 20 are attached there. All that is required is that the dimensions of element 20 and base element 10 with regard to the arrangement of the opening 11 and projection nose 21 are coordinated. Instead of just An opening 11 and protruding nose 21 could also be placed side by side be coordinated.

FIG. 13 shows a perspective view of the basic element 10 according to FIG. 1 with additional elements 20 and 30 attached to it. Either, as shown, all additional elements are attached to the basic element at the same time, or only one of them, possibly then additionally the rod-shaped additional element 90 9 or 10, arranged in one or more of the openings 11 to 14.

The additional element 20 is with its projection 21 in the central opening 11 of the basic element 10 shown in an engaging manner. The bottom of the basic element is supported on the straight areas 22 of the additional element 20 on. The hook-shaped clamping elements 23 encompass the longitudinal edges 15 of the Base element 10 and store with their outer extents on the top of the basic element. A tilting of the additional element during the Swimming, for example when hand is engaged in the middle elongated Opening 12 and on the outer edge 16 with the inner bow or from the other side into the elongated openings 13, 14 on the outer edge 17 with the outer arch, this is only in small areas, in particular 2-3 cm in relation to the lower edge of the curved end 24 possible. The actual water resistance is determined by the surface 25 of the additional element 20 created.

For backstroke exercises, the plate-shaped grip element 30 is attached to the Base element 10 attached. This happens because the plate part 33 the underside of the base element, with the handles 31 through the elongated openings 13, 14 of the base element are inserted. On these handles 31 can now be attacked by the swimmer with his hands. He must stretch with the upper body, causing a swimming technical Considerations are forced out of optimal supine position. additionally the additional element 20 can be attached to the base element 10 at the same time create a water resistance, which trains footwork in particular becomes.

Alternatively, the feet of the swimmer can be inserted through the handles 31 and arm work is trained.

The basic elements and additional elements shown in the previous figures can be of any size. For example, different Dimensions of basic elements intended for children and adults become. Dimensions of approx. 500 x 290 mm for adults and 350 x 220 mm for children. The material thicknesses the basic elements or additional elements are, for example 30 to 40 mm with essentially rectangular basic elements or 35 to 50 mm for round or polygonal designs. The Elongated openings can have dimensions of 110 x 30 mm, for example have, the central openings for example a diameter from e.g. 50 mm shows. The additional elements that create a water resistance For example, 20 have a width of 390 mm and a height of 180 mm. The surface 25 generating the water resistance has, for example a height between 80 and 200 mm.

The plate part 33 of the plate-shaped grip element 30 is made of, for example cut or punched out of a 3 mm thick plastic plate. The Loops 35 consist, for example, of a 6 mm thick nylon cord, the ends of which are knotted on the underside of the plate part. Between Knots and the underside of the plate part are preferably washers made of plastic to prevent the knots from slipping through for example 8 mm thick holes are provided in the plate part.

The rod-shaped additional element 90 has a diameter of, for example 50 mm, or with tapered ends a diameter in the middle of approx. 65 mm and in the end area e.g. 38 or 48 mm depending on the diameter of the central opening of the respective basic element. The End areas can be, for example, 120 mm long. Its length is e.g. approx. 1500 mm.

The flat basic elements are suitable for their application dimensioned, with for example a basic element for gymnastic Exercises for several people (see Figures 5 to 8) should be larger is used as a basic element for only one person, for example in FIG. 3 or 4. But also the dimensions of the additional elements, namely of the water resistance generating member 20 and the plate-like one Handle element 30 are based on the respective application or also depending on body size, depending on the handles dimensioned by the hand size or the height of the feet of the user.

The additional elements 20, 30 can with suitably shaped openings and dimensions can also be attached to known basic elements, whereby their advantages can then also be used with these.
