Description

The present invention relates to a sports device with the features of the patent claim 1.

There are known sports equipment or exercise bikes that have a frame on which chem movement elements for the arms and movement elements for the legs are movably arranged. Such devices are usually extremely bulky and are firmly anchored to the floor in a gym or the like.

The present invention is therefore based on the object of a sports device create with which the force used to move the whole Sports equipment can be implemented, the sports equipment in relatively lighter Construction is formed. Furthermore, the task is a relatively articulated lap sporting equipment especially for the elderly or for rehabilitation to accomplish.

This object is achieved by the entire teaching of claim 1. Advantageous embodiments of the invention result from the subclaims Chen 2-39.

According to the invention, the sports device comprises first movement elements which are attached to a Frame are hinged and individually or together based on the Ge adjust in the manner of a forward and backward movement swiveling and by hand handle areas are provided. Furthermore, the sports device includes second with drive or brake elements provided movement elements and transmission elements elements by which the movement of the first and second movement elements can be coupled to one another or in pairs and / or on drive elements or on  Brake elements is transferable. With this sports device, the user can ski make cross-country movements when the first movement elements are additional Lich with step plates that are essentially parallel to the frame are provided, and therefore also a ski length in summer or in the "dry" perform running training. Such athletic movements are particularly of older people easily feasible. It is also for rehabilitation purposes Sports equipment can be used. In addition, the optional arrangement of Drive elements the possibility that the kinetic energy used in a movement of the entire sports equipment can be implemented. together Men with sporting activities can use the sports equipment as a form of advancement be used. Become brake elements instead of the drive elements used, the sports device can also be used as a stand-alone device. B. Use in a room find. Accordingly, the sports equipment is extremely versatile when Drive and brake elements can be replaced in a simple manner.

The first movement elements can be arranged left and right of the athlete be and can be swiveled in opposite directions or in the same direction. The first movement elements can be designed in particular stick-like or rod-like and are operated like cross-country poles. The opposite pivotability can be carried out in particular with the diagonal step-like movement, while pivoting in the same direction is like a double-decker thrust comes. So the typical movements are like cross-country skiing with the Poor feasible.

The first movement elements can be coupled or uncoupled his. It is advantageous if an adjustment device is provided that the movement tion elements from the coupled to the uncoupled position and vice versa can switch easily. The first movement elements are copied pelt, there is an inevitable movement of one arm depending on the Movement of the other arm. For example, the opposite movement  tion of the first two movement elements can be set. In uncoupled Position, the first movement elements are independent of each other movable backwards.

The frame can be particularly advantageous on at least one floating body be arranged, the drive elements then paddle-like or propeller-like can be trained. The sports equipment then serves as a means of transportation the water, the user or athlete unlike what is known water vehicles (e.g. pedal boats, rowing boats or the like) in an upright position Position the sports equipment can operate or drive. The floats should constructed in a basically unsinkable version and against one external effects, such as B. suddenly occurring higher swell, ver be stiff. This ensures that the entire sports equipment is at rest the sinking and damage to the entire float frame mens is not possible.

The drive element can have at least one surface element, which at Immersed movement against the drive direction in the water. To ent To ensure the speaking drive, several can be on one drive element Surface elements can be arranged one behind the other. For effective transportation the surface elements can be designed in the shape of oars or paddles. Will that Moving sports equipment in the drive direction, the surface elements lie flat on the bottom the floor area of the frame. To prevent the device from sliding enable, the surface elements are still in essence even at a standstill Chen parallel position to the bottom area of the frame. Once a force introduction If the drive elements are used, the surface elements are immersed in what water and drive the sports equipment.

A particularly stable and unsinkable swimming device is obtained if the Floating bodies lie next to each other like a catamaran, the drive elements  elements can be arranged outside and / or between the floating bodies. With this arrangement, the recess in the middle of the two Float the movement elements and the tread plates can be arranged. The floats can e.g. B. both slim, racing boat-like or flat, be a little wider in the way of surfboards.

The arrangement with only one float is possible, the one with Ausle likes to be supported to prevent tipping. The boom can be so Brings that the boom pulled up at a sufficient speed can be gen.

The transmission elements can be made as a rod in a simple and stable manner be formed, the articulated between the movement elements and / or the drive or brake elements are attached.

Alternatively, the transmission elements can also be used as deflection rollers between rule the first movement element and the tread plate or between the second movement element and the drive or braking element be, with cables or bands, in particular rubber, on the deflection rollers tapes are rolled up. The movement elements can be articulated Grasp the connecting rods on the cables. For example, at the tread plates also with a toothed belt or strap-like connection be coupled to the first movement element. The use of rubber bands has the advantage that when driving forward the blocked engagement on the wheel not suddenly, but fluently.

The transmission elements can have axes on which two um swivel castors with different diameters are arranged, one order steering roller with the first movement element and the other deflection roller with the second movement element is operatively connected.  

The design of the transmission elements as deflection rollers has the advantage that between the two pulleys, a hub gear like a bicycle can be arranged with which one can freely move between different ones Can switch translations. The deflection rollers can then be the same Diameter.

As already indicated above, the frame can be designed as a stand frame, the movement of the first and second movement elements on the brake elements is transferable. Advantageously, the sports device from the driving or Swimming device can be converted into a free-standing device. The braking elements can be designed as drums or rollers on which cables or belts, ins special rubber bands are rolled up so that the so-called Forward drive creates an adjustable tension and thus for strength training contributes. Of course, other types of braking mechanisms, e.g. Legs hydraulic arrangement, possible. An ergometer can also be connected to be able to measure the work performance of the athlete.

Instead of paddle or propeller-like drive elements, the drive elements can Mente also be designed as wheels, so that the sports equipment in the country can serve as a means of transportation.

The second movement elements can also advantageously on the frame be guided essentially in parallel. In particular, the first and second Movement elements run essentially parallel to each other, which the Compactness and stability of the sports equipment supported.

The tread plates can expediently be made by means of a detachable connection be attached to the frame, so that the Zwangsbewe when loosening the coupling tion between the foot plates and the handle areas. The Foot plates can e.g. B. with immovable stand plates that are not with the movement  tion of the first movement element are connected, exchanged. In this way it is possible to work exclusively with the arm strength z. B. sitting to move or to train the arms.

Because of the possibility of coupling between the first and the second Movement elements, it is of course also possible that by the sole Betä adjustment of the first movement elements or the foot plates, a propulsion or a Power transmission to the brake elements can be achieved by either only attach the foot plates to the drive or braking elements by moving the foot peln or just the first movement elements to the drive or brake couple elements.

The bottom area of the frame can have rails on which the step plates are guided. In addition, the tread plates can be provided with rollers, which are guided in the rails for a friction-reduced movement are.

The tread plates can be particularly advantageous with a type of binding Cross-country skis should be provided. This is particularly important when driving strongly Swinging out of the kicking back foot possible. At the same time, too an increase in the step motion of both feet working in opposite directions or legs on the two step plates possible. In an alternative embodiment tion variant can tread elements on the tread plates. B. with a folding Hinge can be pivotally attached, the tread elements an additional bin dung like a cross-country ski.

The stand plate already mentioned above, which alternatively or in addition to the be movable tread plates can be provided on the base area of the frame, can advantageously also by means of a releasable connection on the Ge stell be attached.  

The frame can have two roof-like supports at the edges Carrier, in particular support rods, with which the entire sports equipment necessary stability is given. In addition, between the support beams at least one cross member, in particular a cross bar, may be provided in order to support the rigidity of the entire arrangement and twist in particular to prevent especially when actuating the movement elements.

Furthermore, a diagonal coupling device can be provided, which consists of a with the frame connected shaft, which at one end one after projection at the top and a downward projection at the other end Has projection, on each of which a first movement element be articulated is consolidated. This will force a diagonal movement from left and right movement element initiated. Conveniently, this Koppe lung be solvable by z. B. one of the connecting levers slidably becomes. If at least one connection with the projection is released, the Ge levelness of the handles.

The cross member described above can be provided in the form of the shaft, which thus fulfills two tasks, namely on the one hand the support function or Stiffening of the frame and on the other hand the joint function for the movement supply elements and in particular the coupling function.

The transmission element between the first and second movement element can be arranged between the respective pivot points of the movement elements. This can also be a specific gear ratio of the Bewegungsge speed of the two movement elements can be set.

The fulcrum of the second movement elements can be above the fulcrum of the be positioned first movement elements. This is the force application of  the first movement elements into the second movement elements in optimal Way possible.

Advantageously, the pivot point of the transmission element on the first and / or second movement element can be changed, with which difference leverage ratios and thus different speeds of the two th movement element can be adjusted. For example, in Anfahrsi tuations of the swimming device can be advantageous if a greater force input device in the second movement element by means of a corresponding lever will act, which at the same time with a reduction of the way and the Ge speed of the drive element is connected. The swimming moves is already moving at a certain speed, another translation can be made tion ratio can be set, the pivot point of the transmission element Change mentes on the first and / or the second movement element accordingly is changed.

Advantageously, at least one articulation point of the transmission element be changed by an actuator in the handle area. The first and / or second movement element can for the different articulation points the transmission element a plurality of detents for fastening the Have transmission element.

In a further embodiment variant, the step plates with An drive elements, e.g. B. with paddle or propeller-like surface ele elements. This could increase the feed rate and thus the speed ability to be increased.

There can also be a direct coupling of the tread plates to the drive or  Brake elements can be provided without the first or second movement move elements. This is a propulsion solely through a foot or leg movement feasible.

At least one rudder (for swimming model) be arranged on at least one floating body. The rudder can be controlled using levers or cables. This can be conveniently done in At least one handle area can be provided with a twist grip Rotation the levers or cables can be operated.

Of course, a different type of control or steering can be used for the driving model be seen the z. B. is usually provided in vehicles with wheels.

Reference number 1 designates the sports device in its entirety. However, Fig. 1 shows a side view of only the essential elements of the sports device 1, the bottom portion 23 is only partially shown. The sports device 1 comprises first movement elements 2 which are articulated to a frame 4 and can be pivoted individually or jointly with respect to the frame 4 in the manner of a forward and backward movement, as shown in FIGS. 5-8. The first movement elements 2 are rod-shaped and provided with handle areas 5 at their upper ends. Furthermore, the sports device 1 includes second movement elements 3 , which are provided with drive or braking elements, and transmission elements 8 , 9 , 10 , by means of which the movement of the first 2 and second movement elements 3 can be coupled to one another or in pairs and / or to the drive or Brake elements is transferable. Furthermore, the first Be movement elements 2 with respect to the frame 4 substantially parallel GE guided tread plates 6 , 7 are provided. The first and second movement elements 2 , 3 are each provided in pairs and designed as rods, the first movement elements 2 being arranged to the left and right of the athlete 11 and being pivotable in the same direction or in the same direction.

With the sports device, the user or athlete can carry out cross-country movements of any kind, while at the same time using the drive elements as a means of transportation. By means of the opposite or same-directional pivoting of the first movement elements 2 and the tread plates 6 , 7 coupled thereto, both diagonal step-like movements and double stick-thrust movements are possible. The sports device 1 can therefore be used special for cross-country skiing training.

The first movement elements 2 , which are arranged on the left and right of the athlete 11 , can be coupled or uncoupled. If the movement elements are coupled with each other, the other element is inevitably carried along when one element moves. This can be particularly advantageous when the bars move in opposite directions, so that the athlete is always forced to perform the corresponding movements.

As shown in the drawing figures 3 and 4, the frame 4 is arranged on two floating bodies 12 , 13 which are next to each other like a catamaran. The drive elements are designed like paddles or propellers (paddle element 14 ). The paddle-like drive elements have one or more surface elements 15 , which are immersed in the water when moving against the drive direction (see FIGS . 7 and 8). With pivoting of the first moving element 2 to the front (Fig. 5 and 6) and the second moving element 3 is pivoted forward ge, wherein said paddle member is drawn also to the front 14 and the surface elements 15 folded at the lower bottom portion 23 of the frame 4 abut. When the first movement element 2 moves backwards ( FIGS. 7 and 8), the second movement element 3 is also pivoted backwards and the surface elements 15 arranged thereon are pulled towards the rear in the opened state. Due to the resistance in the water, the floats 12 , 13 or the entire sports device 1 are moved forward vigorously (to the left in the drawing figures). The drive elements, ie the paddle elements 14 are arranged between the floating bodies 12 , 13 .

In Fig. 15 an alternative movement initiation with power transmission of the pad delelemente 14 is shown. The arranged on the first movement element 2 surface element 15 turns transversely when initiating movement against the direction of travel. Alternatively or additionally, the paddle or surface element - as shown in FIG. 16a) - can spread apart. The athlete 11 can thus use his power to move the sports device 1 forward through the resistance of the spread and / or transverse paddle in the water. Referring to FIG. 15, the FLAE can chenelement 15 at the lower end of the second moving member 3 via a hinge-like device 52 to be such that around the longitudinal axis of the moving element a movement of the surface elements 15 is possible by about 90 °. For this purpose, the hinge-like device 52 is positioned outside the longitudinal axis of the surface element 15 . The surface elements 15 can also be arranged in another fluidically favorable extension of the second movement element 3 Be. The surface element 15 itself is preferably designed so that it exerts the lowest possible water resistance when pulling forward in the water, that is to say that no curvature in the longitudinal direction, but son may have a slight curvature in the transverse direction.

With reference to FIG. 16, it is also clear that the paddle or surface element can move in a folding manner about a horizontal axis 53 . In the driving backward movement of the paddle, the paddle according to FIG. 16a is spread on and set up, in the case of counter to the forward movement by the water sliding movement according to FIG. 16b, the paddle element 14 is folded on the one hand and on the other hand about the axis 53 to the rear placed in order to offer the water as little flow resistance as possible. Only when the paddle is again moved forward in the water does the paddle stand up and, if necessary, the paddle also spreads apart, but rigid, non-spreading paddles can also be provided.

If only one floating body 12 is provided, as in FIG. 9, this is supported with cantilevers 16 in order to prevent the sports device 1 from tipping, especially during the starting process. With sufficient movement of the sports equipment 1 from the casual 16 can be pulled up.

The transmission elements 8 , 9 , 10 are designed as rods which are articulated between the movement elements 2 , 3 or the second movement elements 3 and the respective drive elements and between the first movement elements 2 and the tread plates 6 are attached.

2, the transmission elements are designed as axes on which two deflecting rollers 18 , 19 with different diameters are arranged. The sports device is designed in this case as a driving model in which the drive elements are designed as wheels 22 . Cables 17 are rolled up on the deflection rollers 18 , 19 and are connected to the first and second movement elements 2 , 3 via articulated connecting rods 35 . One of the two deflecting rollers 18 is in operative connection with the first movement element 2 and the other order steering roller 19 with the second movement element 3 . The at the guide rollers 18 , 19 are firmly connected to each other, so that a certain step up or step down can take place. However, a hub gear can also be arranged between the two deflection rollers 18 , 19 in order to achieve a multi-gear ratio. The wheels 22 are arranged on the deflection rollers.

In Fig. 10, the frame 4 is designed as a stand frame, in which the movement of the first and second movement elements 2 , 3 are transferable to brake elements 20 . The braking elements 20 can be designed as rollers, drums or the like, on which the cables 21 are rolled up.

Referring to FIG. 11, the sports device 1 is also formed as a driving device, said driving elements are provided as wheels 22. In this way, the Sportge advises 1 is also movable on firm ground. Of course, the wheels 22 can also be used in the driving model via other mechanisms, e.g. B. cables or the like are connected to the movement elements.

The first and second movement elements 2 , 3 are arranged essentially parallel to the frame 4 and to one another.

The foot plates 6 are BEFE Stigt by means of a releasable connection on the frame 4 . You can therefore be removed so that the first Bewegungsele elements 2 are only operated with the arms. The bottom region 23 of the frame 4 has rails 24 ( FIG. 4) on which the tread plates 6 are guided. For easy mobility of the tread plates 6 , these are provided with wheels 25 which roll in the rails 24 .

As shown in FIGS. 1 and 2, 6 tread elements 27 are pivotally attached to the tread plates, the tread elements 27 having a binding 26 in the manner of a cross-country ski. The shoe 42 of the athlete 11 is articulated in the binding 26 with its front tip. As a result, the athlete's foot can swing out like a cross-country skier and dynamic, sporty movement of the legs is possible.

In addition, a base plate can be seen on the base area 23 of the frame 4 , which can be fastened by means of a releasable connection. However, such a base plate is not shown in the drawing figures.

The frame 4 has on the edge two roof-like support rods 28 , 29 which are connected by means of a cross member (shaft 30 ). This construction gives the frame 4 high stability and rigidity. The shaft 30 is characterized in that it has an upward-pointing projection 31 at one end and a downward-sending projection 32 at the other end, to each of which a first movement element 2 is articulated. As a result, a forced diagonal movement is initiated, which can be uncoupled again by releasing a connection with a projection 31 or 32 .

The transmission element 8 between the first and the second movement element 2 , 3 is arranged between the respective pivot point 33 , 34 of the two movement elements 2 , 3 movement . The fulcrums 33 , 34 are located on the tip of additional support beams 43 , 44 which are provided on the frame 4 . The ratio of the distance from the pivot point 33 to the pivot point 36 and the distance from the pivot point 34 to the pivot point 37 is 2: 1 in the drawing figures. The shortened lever from the pivot point 33 to the pivot point 36 causes a greater introduction of force into the second movement element 3 , This also leads to a reduction in the path of the paddle element 14 and thus to a reduced speed. This is an advantage, particularly in start-up situations of the sports device 1 . The pivot point 34 of the second movement elements 3 is positioned above the pivot point 33 of the first movement elements 2 .

The point of articulation of the transmission element on the first and / or second movement element can be changed so that different transmission ratios can be set for different driving situations. At least one articulation point 36 , 37 of the transmission element 8 can be changed by an actuating element, which is not shown in the drawing figures, in the handle area 5 . To set different lever arms or transmission ratios, the first 2 and / or second movement element 3 has a plurality of catches 38 for fastening the transmission element 8 .

In Fig. 12 drive elements in the form of surface elements 15 are also coupled to the stepping plates 6. This means that a higher driving speed can be achieved.

A control rudder 39 is arranged on the floating bodies 12 , 13 for controlling the sports device 1 (see FIG. 4). The control rudder 39 can be controlled via levers or cable pulls, a turning handle 41 being provided in the handle area 5 (see FIGS. 13, 14), by means of which the cable pull 40 can be actuated.

The actuating element shown in FIGS. 13 and 14 is designed as a rotary handle 41 , which is arranged vertically movable on the first movement element 2 via a joint 45 . As a result, the movements of Bewegungsele mentes 2 can be fully performed without the rotary handle 41 itself being pivoted up or down. Rather, the rotary handle 41 remains in a horizontal position. The rotary handle 41 is also attached to a pipe section 46 (or a similar element) that is slidably arranged on the first movement element 2 . With the help of an adjusting screw 47 or a locking bolt and a more number of holes 48 in the first movement element 2 , the pipe section 46 can be adjusted so that the athlete can make his optimal, ergonomic setting.

The rotary handle 41 itself is rotatably mounted on an intermediate piece 49 in and counterclockwise. The rotatability can be secured against twisting with the help of a locking and release system in the manner of a shepherd's teeth (if necessary, to determine a specific course).

On the rotary handle 41 , a lever 50 is arranged on the side (see FIG. 14), to which a control cable 51 or Bowden cable for controlling the rudder 29 is attached. The rotary handle 41 can also be rotatable about the axis 41 a, for. B. to operate a hub gear. Furthermore, switching or control elements can be arranged in the rotary handle 41 by Bowden cable.

The construction of the twist grip 41 allows an ergonomic adjustment for the respective athlete 11 when force is fully applied in both directions.
