Description

Gymnastics device for performing active and passive movements of the Body The invention relates to a gymnastics device for performing active and passive movements of the body, which essentially consists of a chassis, on which seat, pedals and handlebars designed in the shape of a lenght for the user are articulated, with a motor mounted on the chassis for optional drive of the moving parts of the device in passive gymnastics, with those caused by the pedals or the motor-driven movement devices for the seat and the handles are coordinated and periodically changing movements predominantly against each other in the vertical and horizontal directions with stretching and bending of the arms and legs run by the user.

Such gymnastics devices are known in various designs. They are used as exercise equipment for doing some serious gymnastics too Doctors recommended. These devices are designed to be healthy for people who do not have time to exercise a sport, maintain a good figure and health. The effect of this Device is achieved through tried and tested movements in which the body through the seat lifted about 12 cm and moved the same distance back and forth.

In the process, the handlebars designed in the form of a bicycle handlebar move Hand grips up and down as well as forward by a distance of about 40 to 50 cm at the same time and back. These movements are chosen so that an average grown Body can participate in all movements without being overstrained.

The known devices of this type are characterized by three special ones Features from: a) The movements of the seat and the handles are inevitable with each other coupled, d. In other words, only movements of both parts are possible at the same time. b) All Levers or rods participating in the movement move more or less between the legs of the user or almost to his body, so that for example Women cannot wear clothes when doing gymnastics. Because the levers are like scissors move, there is a risk of jamming, especially if the user of slips off the pedals. c) The levers and linkages also form in the lower position with the fixed parts of the device a relatively high structure above the ground, so that getting on and off especially for the elderly and the physically handicapped difficult is. Should the gym equipment, for example due to a power failure, be at its highest Stand still, dismounting is quite difficult even for healthy users.

It is therefore the aim of the invention to create a gymnastics device, while maintaining all the beneficial gymnastic properties the above Disadvantages are avoided, thereby also helping the elderly, the physically handicapped or the sick Enable people to use the device.

There are also known gymnastics equipment in which the movement functions are limited compared to the devices described above. With such Devices should renounce the mobility of the seat and by covering all moving parts can also be used by the physically handicapped. However, the lever for the handles also oscillates in one of these devices the legs of the user, and climbing is significant with all of these devices To overcome height.

After all, a machine is known that is actually no longer is to be counted among the gymnastics equipment. It is more of an amusement device. With this device, the required movements can only be apparent and indicated because the machine is spring-loaded on a frame in which it swings. The body moves during the relative movement of the device in relation to the base not relative to the pedals or the handles. Only the handles can be moved arranged. The gymnastic The effect is therefore similar to that of the last-mentioned devices.

The last-mentioned devices achieve that by the invention Desired benefits only partially and only by doing without essential gymnastic Properties.

Compared to the known devices, the gymnastics device is after of the invention characterized in that the movement devices for the seat and for the handles on rigid columnar fixed on both ends of the chassis Beams are articulated and that the means to transmit the movements of the Pedals or the motor guided within the chassis and the columnar support are. So that all stationary and moving parts are arranged so that for the user a free movement space is created between the two pillars. All moved Parts vibrate outside of this space without the user regardless of their to hinder the respective position.

So you can easily open or in any position of the device descend.

In the device according to the invention none of the other than for gymnastics appropriately proven movements suppressed or restricted. It is quite the opposite possible to change the size of individual movements or as required on and off.

The moving means between the upper ends of the columnar The carrier and the seat or the handles are expediently of lever parallelograms educated. The power transmission from the drive to these movement devices can instead of shear forces done by tensile forces, so that pull chains or ropes can be used. The drive is derived from a central shaft, with which the individual movement devices can be coupled.

Some embodiments of the invention are in the drawings shown.

F i g. 1 shows a first embodiment of the gymnastics device in side view; Fig. 2 to 4 illustrate different positions of movement of the device according to FIG. 1; Fig. 5 shows a section through the device of Fig. 1; F i g. 6 to 8 show, in section, three further exemplary embodiments of the gymnastics device; F i g. 9 illustrates an arrangement for locking the moving devices.

The column 2 carries the movement system on its head 3 on the bearing bolts 30, 31 of the seat 8. The column 9 carries on the upper part 10 on the bearing bolts 38, 39 the Moving devices for the handles in the form of bicycle handlebars 14. An electric motor 15 arranged on the base plate 1 drives a reduction gear 16, from which a shaft 18 protrudes on both sides and carries the pedals 17. The sprocket 19 is located on the pedal shaft 18, which is connected by means of a chain 20 a sprocket 21 mounted in the base plate 1 drives. This wheel is eccentric a bolt 22 is arranged, one of which is in a sleeve 23 to the right and left attached push rod 24, 25 goes out. The push rods are by means of bolts 42 at one arm of the deflection angle lever 26 and 34 articulated, which is attached to the in the chassis Bolts 27 and 35 are mounted. On the second arm of the angle lever are means Bolt 42 a two more push rods 28 and 36 articulated in the columns 2 and 9 are guided approximately vertically upwards. The ends of the push rods 28 and 36 are Via bolts 42b with the drive levers 29 and 37 for the movement devices of the seat 8 and the handles 14 connected.

These movement devices are formed by lever parallelograms. To move the seat 8, there are two levers on the stationary bearing pins 30 and 31 4 and 5 rotatably mounted. The other ends of these levers are in the bearings 32 and 33 are hinged to the seat support 6. In the seat support 6 is an adjustable support 7 out for the seat 8.

In the embodiment according to FIGS. 1 to 5 describe the Parallelogram lever 4, 5 of the seat 8 a deflection of 600, from the lowest position (Fig. 2), in which the angle to the horizontal is about 150, up to the highest position (Fig. 4), in which the angle of the lever relative to the Horizontal is about 75. In this case the parallelogram levers are 4, 5 in covered by the seat 8 in every position.

The drive for the handles 14 is similar to that for the seat 8 designed. At the head 10 of the column 9 are on the stationary pins 38 and 39 Ends of parallelogram levers 11 and 12 are supported, the opposite ends of which are articulated to the handle support 13 by the bolts 40 and 41.

The handle support 13 has an extension 13 a, in which the Handles 14 are adjustable. This extension 13a makes it possible move the column 9 away from the user and so the free space for the user to enlarge.

For the exercise of active gymnastics, the device is used by the user driven by the pedals 17 while the motor 15 is switched off. With passive For gymnastics, the motor 15 drives the device. This will be the user's legs moved with the pedals. In both cases, the seat 8 rises and falls periodically on a circular arc directed towards the handles 14. Move at the same time the handles 14 on an arc of a circle towards the user. The different Movement positions are shown in FIGS. 2 to 4 shown. Fig. 2 shows the deepest Position of the seat and the handles. Fig. 3 shows after a rotation of the pedals around 1800 a middle position, and FIG. 4 shows after turning the pedals through 3605 the highest position of the seat and the handles. After another half turn of the pedals, the seat and handles are in the middle position according to F i G. 3 and after a total of two rotations of the pedals back to the starting position according to FIG. 2.
