Description

The invention relates to a training device.

Stationary home bicycles, which are used as training devices, have been known for a long time. These have the disadvantage that only the leg muscles are stressed and the body and arm muscles remain almost unused, so that the entire circulation is not optimally stressed. The situation is reversed in the case of so-called rowing machines, where primarily the arm muscles are stressed less than the leg muscles. With both types of exercise equipment, there is the additional fact that you exercise while seated. The diaphragmatic breathing is severely impaired because the lower body is angled.

The object of the present invention is to provide a training device with which a uniform load on the leg, body and arm muscles can be achieved and normal diaphragmatic breathing is possible and with which the whole body may be challenged more.

This task is solved with a training device which has the following features:

a) a stand which can be leaned against a horizontal base and a contact surface forming an acute angle with it,

b) two upper handles movably guided in the upper area of the stand, and c) two lower foot levers or footsteps movably guided in the lower area of the stand.

Here, for. B. the training device has the following features:

a) a stand that can be leaned against a light reserve between a horizontal base and a vertical contact surface;

b) two upper levers articulated in the upper region of the stand, which can be pivoted in opposite directions about a common horizontal axis;

c) a variable friction brake acting on the upper levers;

d) two lower levers which are articulated in the lower region of the stand and can be pivoted in opposite directions about a common horizontal axis;

e) a variable friction brake acting on the lower levers.

The training device according to the invention is based on the natural, stretched posture of the human body and simulates the circulation-promoting and pulse-increasing climbing movement, such as is used for mountaineering. Here, leg and arm muscles are put under intense stress at the same time. A positive breathing function is guaranteed both by the non-angled vertical posture and by the rhythmic lifting of the arms and thus the chest. The device is so simple that it can be used by younger, well-trained as well as older, less experienced users. The device takes up little space and does not need to be fixed to the wall. Operation is simple, so that even technically untrained people have no problems using it. The device can only be adjusted once to the body size, which can be done using a body size scale. The circulatory stress can be adjusted continuously so that healthy people as well as people in the convalescence stage can perform light and increasing exercise therapy exercises every day. For use in the home, it is important to know that there are no disturbing noises when using the device.

The angle a between the horizontal base and the stand of the training device should be approximately 80 °.

An abutment shell for the buttocks area of the user can be mounted on the stand. This is expediently carried out on a slide which is displaceable on a guide structure which is fastened to the stand.

The length of the stand can be changed so that the training device can be adjusted to the individual body size of the user.

The upper levers expediently carry handles at their free ends, by means of which compressive and tensile forces can be transmitted to the levers.

In a corresponding manner, the lower levers are advantageously provided with pedals at their free ends.

To achieve an optimal training effect, the upper friction brake should be adjustable so that the force required to operate the upper lever is between 30 and 300 N. Accordingly, the lower friction brake should be adjustable so that the force required to operate the lower lever is between 50 and 1000 N.

An opposing positive coupling can be provided between the upper levers and / or the lower levers and optionally between the respective left and right levers.

To increase the stability of the device, it is advantageous if the locations at which the stand rests on the base surface or the contact surface are designed as rubber pads.

In the drawing, several embodiments of the subject of the invention are shown. Show it:

1 shows an arrangement according to the invention in a side view in a schematic representation,

Fig. 2 shows a variant of the arrangement of FIG. 1 again in side view and in a schematic representation and

Fig. 3 shows a detail of a third variant of the object of the invention again in side view in a schematic representation.

1 comprises a stand 1, which is leaned upright but in a light reserve position between a horizontal standing surface 2 (room floor) and a vertical contact surface 3 (wall of the room). The angle a between stand 1 and standing surface 2 should be approximately 80 °. The stand 1 has, for example, two longitudinal struts 4 (one recognizable in the drawing) which are connected to one another by suitable cross struts (not visible). Each longitudinal strut 4 consists of two telescoping parts 4a, 4b, so that the total length of the longitudinal strut 4 can be adjusted. The set length is with a screw or the like. (not shown) fixed.

The lower longitudinal strut part 4a rests on the base 2 via a rubber cushion 5. In a corresponding manner, the upper longitudinal strut part 4b, which is angled toward the contact surface 3, has a contact pad 6 made of rubber. This ensures the stability of the leaned training device.

A guide structure 7, for example composed of two parallel guide columns, is attached to the lower longitudinal strut part 4a on the side facing away from the contact surface 3, on which a carriage 8 is slidably mounted. The carriage 8 carries an abutment shell 9; its position on the guide structure 7 can be fixed, for example by screws (not shown).

On the upper longitudinal struts 4b each have a lever 10, 11 pivoted, which can be pivoted between an upper and a lower end position. The outer ends of the levers 10, 11 are provided with handles 12, 13. These are designed so that both tensile and compressive forces can be transmitted to the levers 10, 11 via them. The force required to pivot the levers 10, 11 can be varied with an adjustable friction brake, shown schematically at 14. You should be able to change between about 30 and about 300 N.

Forced coupling of the levers 10, 11 is preferably provided such that they can only be operated in opposite directions.

A lever 15, 16 is also articulated on each of the lower longitudinal strut parts 4a. The free ends of the levers 15, 16 carry pedals 17, 18 which serve as standing surfaces for the user's feet.

The lower levers 15, 16 can also be pivoted between an upper and a lower end position, the force required for this should be variable between approximately 50 and approximately 1000 N. The force is adjusted using a variable friction brake 19.

The lower levers 15, 16 are also positively coupled such that they can only be pivoted in opposite directions.

The training device described is used as follows:

First, the length of the stand 1 is adjusted to the body mass of the user by relative displacement of the longitudinal strut parts 4a, 4b. The carriage 8 with the contact shell 9 is positioned such that the buttocks of the user standing on the pedals 17, 18 lie against the shell 9. The friction brakes 14, 19 are set in accordance with the desired training effect.

The user standing on the pedals 17, 18 and leaning back a little, grasping the handles 12, 13 with his hands, now moves the limbs in the opposite direction in the following sense:

A lifting of the right foot resting on the pedal 18 is accompanied by

a lowering of the left foot resting on the pedal 17;

a lowering of the right hand engaging on the handle 12;

- A lifting of the left hand acting on the handle 13 and vice versa.

So not only arms and legs move, but also the right and left limbs in opposite directions.

This corresponds to the natural movement of humans.

The opposite correlation of the movements of the upper levers 10, 11 with the movements of the lower levers 15, 16 is expediently carried out by the user. If necessary, a corresponding forced coupling can also be provided here.

2 has a stand 20 which can be leaned against the horizontal base 24 and the contact surface 25 forming an acute angle with it and which consists of two parts 21, 22 which are attached to a frame indicated at 23 are and which are each formed by an endless belt 26,27, which is guided around two deflection rollers 28,29 and 30, 31 each at the end of the lot. These each carry the upper handles 32, 33 and the lower foot levers 34, 35, e.g. endless belts consisting of chains, the longitudinal center axes of which are aligned with one another, are in a driving connection with one another in such a way that they rotate in opposite directions by their mutually facing deflecting rollers 29, 30 being connected to one another via a screwed endless belt 36, likewise consisting of a chain. (Instead of this screwed endless belt, you can of course also use gears that are not shown further). If the endless belts consist of chains that run around sprockets or gears,

the sprockets or sprockets can be exchanged for wheels of a different diameter, in this way one can adjust the force that must be applied by the user, which is indicated at 37.

The length of the endless belts can be changed to match the figure of the user by adjusting the pulleys against each other. This can also be done in a variant, not shown, in which the stand contains a single endless belt, each of which has a deflection roller at its upper and lower ends, e.g. a chain roller is put around.

In the embodiment shown in FIG. 2, the training device has the shape of a fixed ladder, one half of which is formed by the stand or the two parts 21, 22 of the stand which are attached to a common frame 23 and the other half by a support bracket 38 which contains the contact surface will be in any position, e.g. is adjustable at an angle of ± 30 °.

In the variant according to FIG. 3, at least the lower foot levers or footsteps consist of two permanently arranged pneumatic or hydraulic working cylinders 40, 41 arranged in an axially parallel arrangement, which are attached to the stand in an arrangement parallel to the longitudinal axis of the stand and in each of which a piston 42, 43 is movably guided back and forth, which is connected to the foot plate or the foot lever 44, 45 or with a handle - when assigned to the upper area of the stand. In the embodiment shown in the drawing, the pistons in the two working cylinders can be guided to perform mutually opposite movements. In the embodiment shown, each piston is connected to an outer cylinder 46, 47, e.g. B. over the rod 48,49, which forms the top of the foot plate or the foot lever and which is slidably mounted from the outside on the coaxial working cylinder 40, 41 and its length and expediently the length of the working cylinder or at least a substantial part of this length , e.g. corresponds to half the length. In a manner not shown here in detail, the two working cylinders 40, 41, which are at a distance from one another which, measured in a horizontal plane, corresponds approximately to the distance between the feet of a person standing normally upright and e.g. can be about 20-40 cm, connected to one another via a connecting line 50, such that the medium displaced by the outgoing piston of one cylinder can pass into the other cylinder and vice versa, a throttle element 51, for. B. a throttle valve or a throttle screw is connected. In a manner not shown, the working cylinders are each connected to a container for holding the pressure medium supply contained in the cylinder space on one of the piston sides - the piston side that faces away from the other cylinder, i.e. the piston side 42a or 43a - from which the medium comes the declining movement returned to the cylinder chamber.

The new device is therefore used for exercises that are comparable to the movement when climbing stairs, whereby the leg muscles, the veins in the calves and the circulatory system are stressed and adapted to the physical fitness of the user.

A similar modification - according to Fig. 3 - is also possible with reference to the upper handles. Here, too, the upper part - upper endless belt - can be replaced by working cylinders.

The arrangement can also be such that one side of the piston is influenced by a spring which counteracts the downward movement of the piston, e.g. from a compression spring that acts on the underside of the piston.

Finally, variants can also be provided in which the movement of the handles and foot levers or the working cylinder-piston assemblies replacing them does not take place in opposite directions, but in the same direction.
