Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise equipment, which comprises a support which serves as a stand surface for a user's shoes, a shoe holder and a front and a rear side mounted on one shaft by the support. It relates to a type provided with right and left skates resembling short skis with wheels, and a braking device formed by a brake and an operating device.

[0002]

BACKGROUND OF THE INVENTION Skiing seasons are limited to a few months of the year, and because skiing requires a sufficient amount of snow, it is necessary to maintain at least training during the off season. Has already been proposed. This is particularly important and necessary because skis, unlike other sports, impose a wide range of physical requirements and have to master a wide variety of exercise processes. Untrained exercisers often cannot withstand such high demands, resulting in ligament elongation, ligament tearing, muscle stiffening and sprains or even fractures on the first day of ski vacation. This means that vacations that are supposed to take rest often end at the hospital.

Therefore, various proposals have been made for maintaining training by, for example, indoor skiing practice even in a snow-free season or an original winter sports season. Also, exercise equipment has already been developed which makes it possible to simulate or carry out at least several exercise processes. For example, in the already proposed skateboard-like equipment,
A support similar to a short ski has rollers,
At least, it is possible to have a movement course equivalent to long-distance skiing. Almost all known exercise equipment has the same structure as is known, for example, from German Utility Model 8904308.
This known exercise device has a support formed as a stand surface for the user's shoes, a shoe holder similar to a ski binding, and front and rear wheels mounted on one axle with the support. ing. On the rear side, often two wheels are provided. Furthermore, the known device has a braking device consisting of a brake and an operating device, in which case the operating device is housed in the ski pole and is connected to the brake, for example via a Bowden cable.

The disadvantages of the known devices are the high material costs, the low safety and the lack of consideration of a wide variety of exercise processes, loads and a wide variety of demands on the exerciser.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is therefore to improve an exercise machine of the type mentioned at the outset, to be manufactured inexpensively with low material costs and to meet various requirements, for example agility. The object of the present invention is to provide an exercise equipment capable of adapting to extremely hard load-bearing characteristics in high-speed, high-speed driving method or uneven terrain. Further, it is desirable that the exercise equipment provide roller skate shoes and variants for skate shoes.

[0006]

In order to solve this problem, in the arrangement according to the invention, the shaft for fixing the wheel and the wheel are arranged inside the longitudinal extension of the support. did.

[0007]

By virtue of the measures of the invention, the exercise equipment is significantly shorter than the exercise equipment according to the state of the art and therefore costs less material. However, of greater importance is the resulting ease of handling and the greatly increased safety and robustness due to the compact construction.

Advantageously, about 2/3 of the diameter of the wheel lies inside the longitudinal extension of the support. Therefore, the wheels project only very small circle segments on the front side and the rear side. In order to obtain a compact construction of the exercise equipment, the axle to which the wheel is fixed is arranged directly below the support, at least 1/4 of the diameter of the wheel is above the upper surface of the support. Advantageously, the diameter of the wheel is set so that it is located. Wheel diameters of 10 to 20 cm have been found to be extremely advantageous. Such wheel dimensions, on the one hand, give sufficient running comfort, allow considerable speed and sufficient spring bearing, and are such that they are taken especially in quick movements and movements which are similar to skiing. It is large enough to allow a tilted position.

On the other hand, on the basis of such dimensioning, the support is placed closer to the ground, which in turn lowers the center of gravity of the exercise equipment, causing lateral tilting and significant falls. Will be avoided.

Advantageously, the support is assembled from shaped tubes. This makes it possible to use structural materials which are very simple and readily available. In an advantageous configuration of the invention, the two longitudinal beams and the transverse tie are joined to form a very stable support, between which one in front and one in back. Wheels are fitted.

Constructing the support from a molded tube allows another advantageous construction of the exercise equipment. That is, it is possible to use one exercise device for many persons having different shoe sizes, for example, a family member or a member of a sports club. In this case, the molded tube extending in the longitudinal direction of the exercise equipment is divided, and the diameter of the molded tube is adjusted in accordance with the shoe size in which the molded tube is telescopically inserted into and out of each other. Is held as is. When the shaped tubes are joined together by a relatively long clamp, the same purpose is achieved with shaped tubes of the same diameter.

In a further advantageous configuration, the carrier is formed from a U-shaped or T-shaped molding, which has the advantage that the mounting surface for the shoe is particularly stable.

In a further advantageous design of the support, which is structurally simple, the support is designed as a fork in the front and rear, which makes it possible to house the wheel inside the support. However, the middle part remains as a single part.

In a further advantageous possibility for varying the spacing of the shoe holders so that the exercise equipment can be used by users of different shoe sizes, the shoe holders are molded tubes or molded in U-shape or T-shape. Since it is slidably mounted on the body's guide rails, the shoe holder can be loosened, its spacing can be changed by sliding, with a slight effort, preferably by simply unscrewing the screw, and again by tightening the screw. Can be fixed in the position.

A further possibility for adjusting the distance of the two-piece shoe holder consists in providing the support with a row of adjusting holes, which gives rise to the adjusting possibilities.

In a very advantageous design of the exercise device according to the invention, at least one of the shoe holders, preferably both shoe holders, has a hook-and-loop fastener element on its upper side. This hook-and-loop fastener element forms hook-and-loop fasteners with corresponding hook-and-loop fastener elements provided on the underside of the shoe, preferably on the underside of the sole and heel. With this hook-and-loop fastener element, a very simple handling, an improvement in the use of the exercise equipment, and especially a very wide variety of possibilities for the exercise equipment are obtained.

In conventional roller skating and skating, the shoes and the roller skates or skates are usually screwed together and in fact form a unit. This always has the advantage of optimum wearability and great safety, but it also has enormous drawbacks. That is, such a roller skating unit or skating unit is sized for each user, for example such an inseparable combination unit consisting of shoes and unique exercise equipment for each family member. You will need one by one.

A hook and loop fastener of the type described above allows the use of only one exercise device for various users having different shoe sizes. Significant savings in warehouse management are also obtained for commercial purposes. The reason is that it is no longer necessary to stock all of the universal instruments of all sizes. In the exercise equipment provided with the hook-and-loop fastener, only the size of the exercise equipment itself is required,
All you have to do is stock your shoes in a universal size. Another advantage of the use of hook-and-loop fasteners in exercise equipment is that the shoe is held securely and that each foot movement is performed without slip, whereby the exercise performed by the user is directly transmitted to the exercise equipment. It is in. Yet another advantage is based on the separation of the shoe and the exercise equipment made possible in this way, for example, when you want to climb uphill with only the shoes, you can pull apart the hook-and-loop fastener and quickly dissociate the movement to carry the exercise equipment on your shoulder. It is possible to put on the exercise equipment again after the terrain that allows skiing is allowed.

The great importance of the exercise device according to the invention in terms of handling, safety and simulation of a typical course of motion during skiing also applies to the known braking devices in terms of basic principles. That is, in this braking device, the brake is operated from an operating device, preferably from a handgrip, particularly preferably with a ski pole, via a connecting wire leading to the brake, preferably via a Bowden cable. It is like this. Moreover, it is advantageous that such an operation can be performed by remote control using an electronic control unit. This has the advantage that there is never a direct connection between the user's hand and the exercise equipment. In other words, such a direct connection has a certain risk even when the position of the Bowden cable is fixed in the exercise clothes, and it is easily damaged in a fall which cannot always be avoided.

In this case, it is advantageous if the brakes are arranged on both sides of at least one of the wheels.

Such a symmetrical arrangement is particularly advantageous when high velocities are targeted by the exercise equipment without significant directional changes. When using the exercise equipment for a steep descent, it is desirable that the brakes on both sides are also located on both wheels. This allows quick braking and stopping. When braking on both sides of both wheels, it is advantageous for the force to be transmitted to the brakes via scissor levers mounted below the support. The scissors-shaped lever is advantageously provided with a spreading spring, which is adapted to re-release the brake when the operating device is released.

However, for most purposes of use of the exercise equipment, it is sufficient if at least one wheel is provided with a brake, which is preferably arranged on the outside. Such an arrangement has the advantage that it is very labor-free and that the brake can be mounted in a location which is particularly effective for the desired course of movement and which is the least structurally inconvenient. The brake is preferably designed as a band brake and acts on the wheels. An advantageous variant of the braking device is such that the brake acts directly on the rotating shaft carrying the wheels.

In the exercise equipment according to the invention, it is important that only one wheel is provided on the front side and one wheel on the rear side in order to fully realize the fast and similar movements of skiing. There is, of course, some instability in the front and rear wheel arrangements, respectively, to the untrained user, for example any beginner in skating has to fight against such instability. Nonetheless, such instability involves the risk of tipping and slipping. For the purpose of reducing such risks, in a particularly advantageous refinement of the invention, the front and rear wheels are arranged asymmetrically with respect to the longitudinal axis of the support. As a result, the following advantages are obtained. In other words, the exercise equipment as a whole has a particularly good stability, especially with regard to the risk of tilting, without having to accept the great effort and the limitation of the workability of the four-wheel arrangement.

The improvement of the stability of the exercise equipment and the prevention of involuntary tilting movements and lateral slipping-off advantageously further define the central part of the support on which the shoe rests by the wheel diameter. It can be achieved by being offset towards the ground with respect to the wheel axis having a certain position, and thus the center of gravity of the exercise equipment being offset overall towards the ground.

On the basis of the displacement of the central part of the support towards the ground, another advantageous construction of the exercise device is possible, in which the support is guided upwards at both ends in an arch or angle. The wheel is fixed to a shaft fork, which is guided through the end of the support or is connected to the end of the support, for example via a clamp. In this case, the axle fork is also preferably made up of two parts. This allows the length of the shaft fork to be variable, in which case the diameters of both parts are held telescopically slidable in and out of each other. If a shaft fork with the same diameter is made up of two parts, such a variability of the shaft fork length can be created via a clamp or a sleeve. In this clamp or sleeve, if the two parts of the shaft fork are in contact with each other, or if a slightly longer shaft fork is desired, the ends of both parts have a certain distance. Advantageously, the axle fork is mounted on the impact damper. This makes the above-described construction of the exercise equipment particularly suitable for use off course on wavy terrain.

Mobility and adaptation to the skiing, roller skating and skating course of motion is facilitated by a further advantageous variant of the invention. In this variant, the shaft of at least one wheel is designed as a sliding shaft, in which case one or two springs preferably press the wheel into a standard position.
This results in a stabilized position, which is usually caused by a total of four wheels, even in a staggered arrangement of front and rear wheels, for example. On the other hand, during fast movements, i.e. lateral weight transfer, the wheel is moved towards the support while compressing the spring, and during upright and straight-line gliding the wheel is again moved outward by the spring. Pressed.

It has been found to be particularly advantageous for at least one shaft to be designed as a cam slide shaft for turning, for example as effected by the weight shift of the user. In this case, it is advantageous if one or both wheels are mounted on the sliding sleeve via spherical bearings, and that the compression spring stabilizes the wheel in the middle during a straight run. During weight shifts that produce compressive or centrifugal forces, the sliding sleeves cause the wheels to slide along the cam slide axis to facilitate curve mastering and turning.

It is advantageous if the slide shaft or the cam slide shaft is provided with a locking device. By means of this locking device, the sliding shaft or the cam sliding shaft can be deactivated, so that the wheel runs only in the center, which is advantageous during force acceleration.

The value of use of the exercise equipment can advantageously be further increased by additionally equipping it with other accessory parts, such as lights, speedometers, tachometers, odometers. Since it is not possible to exclude contact of the outer region of the support with the ground during fast movements and on curves, it is advantageous to protect this outer region with a replaceable, wear-resistant covering. .
