Description

Underwater trampoline

The invention relates to an underwater trampoline.

Trampolines are used in various designs as sports equipment in the leisure sector and also in the field of competitive sports.

In conventional applications such trampolines are placed in sports halls or possibly also in the outdoor area, for example in amusement parks or the like. In general, in such applications, the trampolines are placed on solid supports on land.

Furthermore, so-called water trampolines are known. Such a water trampoline is known from DE 202 14 276 Ul. This consists of an annular inflatable float and attached to this jump sheet. Through the float, the water trampoline floats on a water surface. The hammock is above the surface of the water, so that a person standing on this jumping mat can do exercises without coming into contact with the water.

The invention has for its object to provide a trampoline with extended functionality.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims. The invention relates to an underwater trampoline with a stored in a frame construction jumping cloth. Due to the inherent weight of the frame construction and / or by means of adhesive elements arranged on the frame construction, the underwater trampoline can be stored in a stationary manner on a support surface under water.

The underwater trampoline according to the invention, because it is completely submerged, enables underwater training, which is considerably gentler on the joints and musculature of the exerciser than on training exercises on land.

An essential advantage of the underwater trampoline according to the invention is that its construction, that is, its internal structure is already designed so that this on a submerged support surface, that is on the floor of a water-filled space segment such as a swimming pool, against unwanted shifts or can be placed secured against unwanted emergence. This allows a person on the underwater trampoline safely perform underwater exercises without the risk of slippage of the underwater trampoline. Additional design measures such as anchorages of underwater trampoline on the support surface or a weighting of underwater trampoline by separate weights are not required to keep the underwater trampoline in its desired position under water.

The level of the jump cloth of the underwater trampoline erected on the support surface is adjusted, in particular by a height adjustment, such that at least a part of the upper body of a person standing on the jump mat projects beyond the water surface. Thus, the term underwater training means that the legs and hips of the person are in contact with the jumping cloth under water, which in particular the movements are subdued when the person arises on the underwater trampoline, whereby the desired protection of the joints and muscles is obtained. Due to the buoyancy forces during the training on the underwater trampoline after the jump of the respective person from the jumping cloth, the return movement of the person to the ski cloth more difficult. To counteract this effect, bands or similar aids can be attached to the underwater trampoline, which can be picked up by the person or attached to the arms or legs so that they can be returned to the jumping cloth by the underwater trampoline.

In order to keep the underwater trampoline on the support surface in its desired position under water, according to a first variant, the weight of the frame construction is suitably dimensioned for this purpose.

The frame construction consists of a landing gear frame and several feet connected to the frame to place the underwater trampoline. The frame construction is formed by a pipe construction, which preferably consists of stainless steel or at least stainless steel.

In order to give the framework the necessary weight, which keeps the underwater trampoline in the desired position under water, the tubes can be filled completely or partially with filling material. This filling material may preferably be formed by rods, in particular iron rods, which can be inserted into the tubes. Alternatively, the filling material may be formed as a pourable material, such as sand, which may be filled into the tubes.

Particularly advantageously, the filling material is introduced into the tubes of the frame construction in such a way that the center of gravity of the underwater trampoline is as low as possible, whereby the support and stability of the underwater trampoline on the support surface under water is considerably improved. For this purpose, the filler is introduced particularly advantageous in the feet of Unterwassertrampolin. This variant can also be carried out in particular if the feet form telescopic devices for adjusting the height of the underwater trampoline.

According to an advantageous variant, at least some of the tubes may be designed so that they fill up when immersing the underwater trampoline in the water with water and thus provide the desired weighting of the trampoline. Particularly advantageous for this purpose, the tubes are used, which form the feet of Unterwassertrampolin. These can for example be screwed to the frame of the frame construction. In the area of the thread, the tubes forming the feet have openings through which these tubes can fill up with water.

According to a further variant, alternatively or in addition to the first variant, the underwater trampoline can be kept in its target position on the support surface under water, that adhesive elements are provided, which hold the underwater trampoline by acting adhesive forces on the support surface. The adhesive elements are preferably attached to the undersides of the feet, so that adhere to the support surface by simply placing the feet on the support surface, the adhesive elements.

Particularly advantageous form the adhesive elements suction cups, which may consist of rubber or elastic plastic.

In an advantageous embodiment, the jump sheet is fixed by elastic elements to the frame of the frame construction, wherein the elastic elements are preferably formed of steel springs or rubber cables. As a result, the necessary for training with the underwater trampoline resilient properties of the jump cloth are achieved. In a further advantageous embodiment of the invention, the elastic elements and the frame can be covered by a cover, wherein the cover is at least partially made of a shock-absorbing material.

The cover protects the exercising person from direct contact with the frame or elastic elements, which could not only be painful but also cause injury.

The underwater trampoline according to the invention can be used without constructive changes both to training exercises on land and in the water. The underwater trampoline can be used as a single unit. Alternatively, several underwater trampolines can be connected with connecting elements to form a multiple trampoline arrangement. As fasteners clamps, brackets and the like can be used.

The invention will be explained below with reference to the drawings. Show it:

Water standing surface.

Foot of the underwater trampoline according to FIG. 1.

Figure 5: Perspective view of a second embodiment of a Unterwassertrampolin. Figure 1 shows a first embodiment of a Unterwassertrampolin 1, which can be used not only for training exercises on land but also for underwater training. All components of the underwater trampoline 1 are designed for this purpose water resistant to chlorine. The underwater trampoline 1 has a frame construction 2 with a frame 3 and four feet 4 mounted thereon. The four feet 4 are identical and arranged in each case at the corners of the frame 3. The frame structure 2 consists of a tubular construction, which preferably consists of stainless steel. With the feet 4, the underwater trampoline 1 is placed on a base, so that the frame 3 extends in a substantially horizontal plane.

In the frame 3 a jump sheet 5 is clamped consisting of a mesh fabric. The mesh fabric may preferably have a PVC coating. The jump sheet 5 is attached to the frame 3 with elastic elements. The elastic elements not separately shown in Figure 1 may be formed by steel springs or rubber cables.

To fix steel springs on the frame 3 may be provided on this weld hook. The advantage of this construction is that the frame 3 can be formed by a completely closed pipe construction, so that the pipes inside do not have to be pickled.

Alternatively, in the tubes of the frame 3, preferably on its underside, holes may be incorporated, in which the steel springs can be hung. This attachment is very easy to implement. In addition, the welding hook, which reduces the overall aesthetics, is saved. However, in this case, the tubes of the frame 3 must be pickled inside. The frame 3 with its rectangular contour can not be pickled as a whole, only straight pieces of pipe. Therefore, for example, the frame 3 consist of a long piece of pipe which is pickled in its rectilinear initial shape and then bent to the rectangular frame 3. This assumes that mounted on the frame 3 feet as further pieces of pipe not to the Corners of the frame 3 are, otherwise the bending process would not be possible. Alternatively, the frame 3 may consist of several pluggable pieces of pipe. Then the feet can be provided again at the corners.

The top of the frame 3 and the elastic members are covered with a shock-absorbing cover 6. The cover 6 consists in the present case of a shock-absorbing layer, in particular a foam material which is fixed on a block or the like as a rigid support. This unit may be encased in a PVC sleeve or the like. The unit thus formed is firmly fixed to the carrier, for example by screw connections. As a result, it is avoided in underwater use that the cover 6 is released from the frame 3 as a result of buoyancy forces.

Particularly advantageously, the cover consists of one or more neoprene elements. The neoprene elements have water-repellent properties and therefore no longer need to be encased with additional protective covers. In addition, it is advantageous that the neoprene elements are stretchable and have elastic properties. The neoprene elements can thus be permanently fixed on the underwater trampoline, for example by sewing with the jumping cloth, whereby a reliable, complete coverage of the elastic elements is always achieved even with acting buoyancy forces.

At the lower ends of the feet 4 suction cups 7 are provided as adhesive elements, which consist of rubber or elastic plastic. Due to the suction forces achieved with the suction cups 7 a secure, stationary hold of the underwater trampoline 1 is achieved on a pad.

This is especially true when the underwater trampoline 1, as shown in Figure 2, is placed on a submerged support surface. The support surface is formed, for example, from the bottom of a swimming pool. The level of the jump cloth 5 is optionally selected by a height adjustment of the underwater trampoline 1 so that one of the underwater Trampoline 1 operator with the upper body still protrudes from the water, that is protruding over the water surface, and so can perform an underwater training on the underwater trampoline 1, in which shock loads on the joints of the person are damped by the subassembly of the underwater trampoline 1.

The underwater trampoline 1 is held solely by its structural design, that is without additional elements such as weights or fastening devices on the submerged support surface, in the present case on the bottom of the pool. It is essential in this case, in particular, that a stop of the underwater trampoline 1 on the support surface is ensured in such a way that lateral slipping or tilting of the underwater trampoline 1 during the execution of the underwater training is avoided.

First of all, the underwater trampoline 1 is securely held on the supporting surface under water in such a way that the dead weight of the underwater trampoline 1 is suitably selected, that is, sufficiently large. This is achieved in the present case by introducing filler material into the tubes of the tube construction forming the frame structure 2.

As filling materials are on the one hand massive moldings, especially rods of iron or the like, which are inserted into the tubes. Alternatively, pourable materials, such as sand, may be used as fillers which are introduced into the tubes.

In order to achieve the highest possible dead weight of the underwater trampoline 1, filling materials can be introduced into all the tubes of the frame construction 2. Alternatively, in order to place the center of gravity of the underwater trampoline 1 as low as possible, the filling materials are introduced only into tubes in the lower region of the frame construction 2, in particular in the feet 4 of the underwater trampoline 1. Another measure for safe stationary storage of underwater trampoline 1 on the support surface are the suction cups 7 at the lower ends of the feet 4. When pressing the suction cups 7 on the support surface is formed in the suction cups 7, a negative pressure by which adhesive forces are generated, the underwater trampoline 1 firmly hold on the support surface.

The structure of such a suction cup 7 is shown schematically in Figure 3. The suction cup 7 consists of a rubber part and has a rotationally symmetrical with respect to an axis of symmetry shape. The suction cup 7 has a first cavity 8, which opens out at the upper edge of the suction cup 7. In this cavity 8, the lower end of a foot 4 of the frame structure 2 is inserted. The suction cup 7 also has a second cavity 9, which opens at the bottom of the suction cup 7 and is bounded by a kreisringfδrmigen wall segment 10 of the suction cup 7. When placing the underwater trampoline 1 on the support surface of the lower edge of the wall segment 10 is pressed tightly onto the support surface, wherein the wall segment 10 is slightly deformed in this case. In this case, a negative pressure forms in the cavity 9, by which the adhesive forces are generated, with which the respective suction cup 7 is held on the support surface.

FIG. 4 shows an embodiment for a height adjustment of the underwater trampoline 1. FIG. 4 shows a section of the frame 3 of the underwater trampoline 1 with a foot 4 attached thereto. The foot 4 in the present case forms a telescopic element consisting of a pipe segment 4 a within whose lower foot part 4b is mounted axially displaceable. The remaining feet 4 of the underwater trampoline 1 are formed accordingly. Depending on how far the foot parts 4b are extended out of the tube segment 4a, the height of the underwater trampoline 1 can be varied. For fixing an adjustment of the foot part 4b, a fastening means in the form of a locking screw or the like is provided. In order to obtain the largest possible weight of the underwater trampoline 1 at the same time low center of gravity, the foot parts 4b are preferably made of tubes, in which filler materials are introduced.

FIG. 5 shows a further exemplary embodiment of an underwater trampoline 1. In contrast to the embodiment according to FIG. 1, the underwater trampoline 1 according to FIG. 5 has a hexagonal frame 3 and six feet 4. Furthermore, in the present case, the cover 6 is hingedly mounted on the frame 3 of the underwater trampoline 1. Otherwise, the underwater trampoline 1 according to FIG. 5 corresponds to the embodiment according to FIG. 1.

In general, a multiple arrangement of underwater trampolines 1 according to FIGS. 1 to 5 can also be used for underwater training. In this case, several underwater trampolines 1 can be interconnected by fasteners such as brackets or clamps.
