Description

The invention relates to a retrofit kit for a training device on which a person exercising rhythmically exercise a training force and this training force while a weight is opposite. Furthermore, the invention relates to a corresponding training device and a tank weight for such a training device.

Training devices are used to specifically train certain muscles or muscle groups in the context of a strength and / or endurance training by a body part of the exercising person is applied under application of a training force against the resistance of a counter force, in the present case a weight force.

Such strength or endurance training can basically in free mobility of the respective body part, for example, with dumbbells are performed. However, this requires a certain training experience and a good sense of motion, since the movement of the body part must be carried out so accurately that essentially only the muscles to be trained are used to overcome the opposing force. In case of incorrect or inaccurate movement of the body part, however, increases the risk of injury and it decreases the efficiency of training.

In order to avoid such disadvantages, a variety of training devices have been developed in which the exercise movement accurately guided and thereby a precise selection of muscle to be trained is possible.

The design of these training equipment differs on the one hand according to the type of the targeted muscles and the other to the body part to be trained. So z. B. extensor muscles trained with actuators, which are pushed away from the body. For the training of the flexor muscles actuating elements are provided, which are attracted against the counterforce to the body. For the training of the arm and shoulder muscles often handles are provided on the exercise machine, while for the training of the trunk and leg muscles padded plates or loops are provided.

Known exercise equipment also differs according to the way in which the counterforce is generated on them. The most widespread is the generation of the counterforce in a mechanical manner by a weight or a training weight. This type of generating the counterforce is on the one hand technically particularly simple and inexpensive to implement, and on the other for the exercising person with regard to the training provided by her training performance particularly vivid. Thus, it is much more motivating and challenging for a person exercising to lift a predetermined weight in the air, as to act against an electromagnetic or pneumatic brake.

At the same time in such known training devices with a movable weight as a counterforce the disadvantage that they are relatively uncomfortable to handle. For example, exercise equipment with movable, individual weight plates are known, which can be assigned by means of a plug-in device to be moved by the exercising person weight or taken away from it. However, the plug-in device can be operated by the exercising person only during training breaks and not during the rhythmic exercise of the training force itself. The rhythmic training exercise must therefore be interrupted for a weight change.

While there are basically training devices known that change the drag even while exercising a training exercise, but these work with electromagnetically or pneumatically generated counter-forces and thus have the disadvantage that the exercising person not directly outweighed by her weight in the form of a body or Weight as such is in mind.

Underlying task

It is an object of the invention to further improve known exercise equipment to the effect that it can be trained more comfortable and overall effective even with simple movement execution, the conversion is made possible for different training devices and disturbing displacements of the weights are avoided during the movement.

Inventive solution

According to the invention this object is achieved with a retrofit kit for a training device according to claim 1 and a training device according to claim 6. Inventive developments of the invention are described in the dependent claims.

According to the invention, a retrofit kit is provided for a training device on which a exercising person can rhythmically exert a training force and this training force while a gravity is opposed, with a fillable with a liquid tank weight, which attachable in exchange for a training device initially attached movable solids weight and a degree of charge changing means for changing the filling degree of the tank weight is set up during the rhythmic exercise of the training force.

With such retrofit kit according to the invention for a training device existing training devices can be retrofitted in a cost effective and simple way and at the same time the persons training on these training devices are offered a considerable improvement in comfort. With the filling degree change device, the degree of filling of the tank weight used in the associated training device can also be changed during an exercise without the exercising person having to interrupt the exercise for this purpose.

Thus, the weight of the force opposite to the training force can be adjusted and thereby the opposing force can also be changed during an exercise, while at the same time the exercising person is aware of the weight moved by it as such.

These advantages are also provided with a training device on which a exercising person can rhythmically exert a training force and this training force is opposed to a gravitational force, with a liquid fillable, movable tank weight and a Füllgradänderungseinrichtung, which to change the degree of filling during rhythmic exercise the training force is set up.

The solution represents an optimum between the manufacturing costs for a training device, the comfort provided to the exercising person and the achieved efficiency of the training carried out.

The weight generation and change is designed as a unit particularly advantageous in the form of a retrofit set, can be supplemented with the almost any training equipment and improved in their training effect.

Particularly advantageously, the Füllgradänderungseinrichtung invention can also be installed from the outset in new training devices already during their production.

In addition to exercise equipment with guided movement, the solution may also be provided for exercise weights, for example in the form of dumbbells, which as such can be raised and lowered by the exercising person in unguided movement.

Particularly preferably, the retrofit kit and the associated training device are adapted to be kept constant by means of their Füllgradänderungseinrichtung during the rhythmic exertion of the training force over a predetermined first time period and / or a predetermined first number of exercises, the degree of filling of the tank weight, while a subsequent predetermined second Time span and / or a predetermined second number of exercises, the degree of filling of the tank weight is changed to lower the weight. In this way, a training method can advantageously be practiced with a training device, as it is currently referred to by bodybuilders as "working down the rack". In this training method, the exercising person works out, so to speak, the dumbbell rack, which means that after a muscle failure a lighter pair of dumbbells or a lower weight is chosen and thus further repetitions of the individual exercise are made.

Alternatively or additionally, in the retrofit kit and the associated training device by means of Füllgradänderungseinrichtung during the rhythmic exercise of the training force over a predetermined first time period and / or a predetermined first number of exercises, the degree of filling of the tank weight, the weight will be increased increasing and over a subsequent predetermined second period and / or a predetermined second number of exercises the degree of filling of the tank weight are kept constant. With this technique, it is possible that the exercising person warms up with a predefined exercise number, before the counterforce of the associated exercise device is finally increased and thus the burden of the exercising person is increased. As a result, in particular training-related injuries to the muscles of a person exercising can be avoided.

Advantageously, finally, the Füllgradänderungseinrichtung provided with an operable by the person exercising during the rhythmic exercise of the training force switch for causing a change in the degree of filling, in particular an attachable to a handle it training device handset and / or a footswitch. The operating options of the training device are significantly increased with such a switch, since the exercising person can vary their load level at any time.

In addition, the filling degree changing device is preferably provided with a control device which is used to count the number of exercises and / or to determine a training duration and / or to determine a pause duration and / or to determine the power provided and / or to trigger a training start signal and / or is adapted for processing a predefined training program. Such a designed control device increases the training possibilities considerably and makes a designed training device to a real one Training partner of the exercising person who, similar to a coach, can specify training programs and training methods and subsequently provide information about training successes. Advantageously, training data can automatically be stored, preprogrammed training templates can be provided, in particular for physiotherapy and prevention training, and also training methods of known bodybuilders can be offered.

The inventively designed tank weight of the retrofit kit explained above is inventively provided with a container wall, which is provided for receiving the liquid filled in the tank weight and which is designed with two oppositely directed into the container interior, slot-shaped indentations. In the case of the tank weight of the training device, by moving the tank weight during the executed training exercises, raising and lowering accelerations as well as impacts on the tank weight can occur which can set the medium or the liquid located therein in motion. This results in particular wave-like fluctuations in the liquid level in the tank weight, which can influence the training itself or at least be perceived as unpleasant. Such wave-shaped movements of the medium stored in the tank weight according to the invention are avoided with the invention in the container wall formed slot-shaped indentations by at least partially separated spaces are formed in the tank weight.

The inventively formed on the tank weight or the container wall indentations are designed over the entire height of the tank weight. With such indentations not only wave motions of the medium are intercepted, but the tank weight designed in this way can also be mounted particularly displaceable on already existing or new training devices. Especially with existing exercise equipment, the weight plates provided there are usually performed on two (chrome) guide rods. At least one of the recesses provided according to the invention can advantageously embrace one of these guide rods and, together with this, advantageously form a longitudinal guide for the tank weight.

The tank weight according to the invention is designed with two opposing indentations. These two recesses can advantageously form a parallel guide for the tank weight in connection with said guide rods. In particular, the conversion of existing exercise equipment is very simple by only one of the guide rods is removed on this, the local solid weight is removed and is then replaced by an inventive tank weight. Subsequently, the guide rod can be reattached and the exerciser reused immediately.

It is also advantageous with the recesses provided according to the invention that the spacing of the guide rods is often not the same for different types of existing training devices. By inventively provided indentations is not tied to a single distance when retooling existing training equipment, but the guide rods need only be different in the indentation be guided into the tank weight according to the invention at different distances from guide rods can. In this way, in particular the mold costs for the tank weight according to the invention and also the conversion costs can be kept very low. Furthermore, the conversion of the training device according to the invention to a larger tank weight is easier and it can be used in new types of exercise equipment with the same or optionally different rod spacings.
