Description

The The present invention relates to an exercise device, preferably isotonic Art.

nowadays The gym offers an extremely wide range of exercise equipment. These devices can be largely be divided into two categories: isotonic devices and cardiovascular devices.

Usually include isotonic devices an exercise position for the User who / his / her physical Strength used to exert a force that counteracts gravity, by acting on a series of passive elements, the forming what is commonly referred to as a "weight block".

at According to the present invention, the training position corresponds to the position, in which the user brings his or her body, whether seated or standing, which means that this position coincides with an area, in which the weight of the body worn by the user with or without footplate from the ground becomes.

Devices of this Kind have a portal frame that is on a vertical plane and to which a certain number of blocks are attached, each one to have a certain weight. The user chooses the Number of blocks that for the required exercise be used, thereby forming a total block with the desired Weight that exerts resistance, muscle strength of the user must become; between the resistance and the active part of the exercise device is located Usually a fastener that is usually off a rope or a wire rope, the / several times wound around pulleys around and serves the resistance to bring to the point where the user his / her physical strength must apply to overcome them.

In the above type of solutions Therefore, the resistance is given by gravity. alternative can do this more complex devices used where the resistance of a motor or a Alternators is generated, which is connected to an electrical energy source is connected and provides a controlled torque.

Which solution is always applied - exercise equipment this Species (as generally used for recreational, rehabilitative or similar purposes Used for purposes) are designed so that the user / the User competes with herself. In other words: the user User must complete a training protocol without any active counterpart, which in the long run to loss of concentration or even to Refusal, exercises perform according to the established rules.

One Another disadvantage is that the proper execution of the Protocol completely depends on the user and therefore difficult is to check the uniformity of the training or the individual Determine progress of one or more exercisers (except this happens in different phases), such as the members a sports group or of persons who have a certain minimum level of fitness need to reach.

Therefore the present invention has the object, the above-mentioned disadvantages to overcome, by offering an exercise device, which allows users, not isolated but in conjunction with other users train so that they are able to, while performing an exercise with each other to interact.

In the 4 . 4a and 4b a further embodiment of the invention is shown.

The device includes a base 401 on which a stand 400 is mounted, which preferably consists of a tube having, for example, an oval cross-section, and as a guide for a working unit 404 serves.

Advantageously, it allows the single upright structure 403 allow the user to completely circle the device and to change their positions relative to the actuators to perform various exercises.

The work unit 404 who are at the lead 403 can be moved through a blocking element 405 be fastened in their respective position; This blocking element consists for example of a clamping screw, which as a whole together with the working unit 404 moves and the vertical guidance 403 detected by touch or overlay.

At the upper end 420 of the stand 400 There are two pulleys 409 which are mounted horizontally side by side while another two transmission pulleys 410 at the bottom, near the base 401 , are appropriate.

The movable work unit 404 is in turn with four pairs of opposite vertical plates 406 between which, preferably rotating about vertical axes, four carriers 408 are mounted on the opposite sides of the stand 403 are arranged in pairs and on each of which a pair of pulleys 407 with horizontal axes, which are arranged vertically one above the other, is mounted.

advantageously, allows it's the rotation of the carriers the users to easily perform both such exercises which requires the actuators to move apart become, as well as exercises, in which the users their positions in relation to the Change control elements have to, by looking around the device to move around.

In the illustrated embodiment, all pulleys 407 at the work unit 404 mounted and can therefore be set as a single part.

It it is understood, however, that the invention also provides that the height the pulleys also independent on the two sides of the stand can be adjusted so that one or both of the tow points one or both users individually set can or can.

The device also includes two wire ropes 412 . 412 ' by appropriate pulleys 407 . 409 and 410 run and through opposite handle pairs 414a - 414b and 415a - 415b powered by two users (not shown) activated on the opposite sides of the stand 403 in the schematically illustrated exercise positions with the number 413 stand.

It It is understood that the handles by adjusting elements or handlebars of any kind, to carry the exercise are suitable to be replaced.

Seen in more detail, put the wire ropes 412 and 412 ' a twin wire cable arrangement, that is a double course of twin wire cables, each of which, for example with respect to the wire rope 412 , at one end to a first actuator 414a is attached, by the overlying pulleys 407 a carrier 408 Standing on a first side of the stand 403 is, runs, and successively through the respective upper and lower pulleys 409 and 410 to get up with the opposite actuator 414b after connecting it through the middle, overlying pulleys 407 of the carrier 408 on the opposite side of the stand 403 has gone.

An identical path through the corresponding middle, upper and lower pulleys 407 . 409 and 410 is from the second wire rope 412 ' that the opposing control elements 415a and 415b connect with each other, go through.

In the embodiment just described, there are two of the pulleys 407 . 409 and 410 on each side of the device, allowing two users to train both arms at the same time, without precluding the possibility of using a single pulley or more than two pulleys, as required.

In operation, the two users, each in his / her practice position 413 , the adjusting elements on the corresponding side of the device and alternately pull on the two control elements (for example 414a and 415a ), so that the two users due to the course, the wire ropes 412 and 412 ' take, work against each other by alternately pulling the actuators.

At a device constructed in this way can be used by the users work against each other or with each other when they are different Types of exercises for the purposes of strengthening muscles, cardiovascular exercise, stretching of muscles or even a workout for one's own body perception, where one of the two users balance the person another test, run.

Thanks to the adjustability of the vertical positives on the work unit 404 and the rotatability of the carriers 408 In addition, the point and angle at which the wire rope is pulled outwards, that is, the direction of the force exerted by the users, can be adjusted to the type of exercise and the body part to be trained become.

Accordingly, the upper or lower pulley of the pulley pairs 407 at the work unit 404 are mounted, depending on the position of the working unit with respect to the handle of the user activated.

Also, the length of the wire ropes 412 and 412 ' which are pulled out of the device, adapted to the type of exercise that the user must perform and to the distance from the device intended for this exercise.

In more detail, the length of the wire rope can be 412 respectively. 412 ' , which can be pulled out of the device, can be adjusted by changing the course of the wire rope so that it exits the lower pulley 410 once or several times around a corresponding pulley 419 , who roll on the stand 403 is mounted, winds and then on the way to the upper pulley described above 409 and continues from there to the opposite actuator.

With this solution, every revolution around the pulley corresponds 419 a reduction in the active length of the wire rope 412 / 412 ' That is, the extent to which the wire rope using the opposite actuator 414a . 414b and 415a . 415b can be pulled out of the device.

Another feature of the device is the upper pulleys 409 in a protective enclosure 427 mounted and with a dynamo 423 connected to a lamp 422 energized, over the training positions 413 the user is located.

If the lamp lights up, it indicates the speed with which the exercise is carried out, and may also represent a performance goal to be achieved.

In addition, the base 401 , which must normally have a certain weight to ensure the stability of the device, from a hollow container 426 exist, which with a filling opening 425 so that for transport purposes the device itself is relatively light but can be made heavier by filling the container with liquid (or with sand or other suitable material) to increase the stability of the device in use. In order to simplify the handling, the device can 4 also with wheels 424 Be equipped with something above the ground at the edges of the base 401 are attached so that they only touch the ground when the stand 403 is slanted so that it is possible to move the device from one place to another.

In the embodiments described above can another resistance, for example, from conventional Weights attached to one or both sides of the device be, in addition to the alternately active and resisting power of the users exercised becomes. This would too strong differences in the respective strength of the two users compensate.

As an example, the 3a and 3b 1 schematically shows a device according to the invention in which a series of weights P, the number and composition of which can change as required, are attached to one of the two user positions.

In the execution of 3a the weights are close to one of the control elements 3 attached, so that the resistance force exerted on the other actuator is increased.

In the 3b are the weights P using an additional system of wire ropes 24 and pulleys 22 attached to one of the two control elements.

If you look at the execution, in the 3b More particularly, the pulleys of the additional system have two grooves, so that the relevant actuator by a first wire rope 24 that around a groove in the pulleys 22 runs, with the other actuator and by a second wire rope, which runs in the same pulleys around a different groove, with the weight block P is connected.

clearly, the weight block P can be changed due to the requirements and be attached to one or both user positions.

The 3b also shows a pressure cell CC, which advantageously at one point 29 attached to the one of the pulleys 22 at the frame 1 is attached.

In this case, the load cell is mounted at the point where the pulley, which is at the symmetrical center, is at the point where the pulley is located Frame is attached, but it can also be attached to any other suitable location.

These solution has the distribution that the load, what the structure and function is measured in a simple manner.

The described invention has obvious industrial applications and she can make changes and variations, without departing from the purpose of the claims becomes.
