Description

Muscle training device

The invention relates to a muscle training device with a tension element (18), a handle element (23) and means (8) for generating a tensile force, wherein the means (8) for generating a tensile force as a spring arrangement (8) are formed, one end of a first point (4) of a lever arm (6) engages and wherein the

Pulling element (18) acts on a second point of the lever arm (6), wherein the second point is arranged at a distance from the first point (4).

State of the art

The known muscle weight training devices have the following problems:

1) Due to the high initial weight at the beginning of the exercise (training process), the entire weight to be exercised is immediate.

2) Joints and ligaments are thus particularly endangered during exercise (high stress) and the risk of injury is therefore high.

3) Exercise equipment that allows you to work out the same muscles requires a very large training surface.

4) The weights are not adjustable to the exact gram. Beginners, need to

Move to the next heavier weight to take big steps.

The prior art also US 4,231,568 A and US 3,558,131 A are called.

Task and solution of the invention

OBJECT OF THE INVENTION: The above-mentioned problems are to be solved.

In particular, the risk of injury due to an increasing training weight should be lower. A smaller site or training area should be achieved by a compact design. The training force should be more precisely adjustable.

This object is achieved in a muscle training device of the aforementioned type according to the invention that the other end of the spring assembly (8) is fixed by a continuously and electrically adjustable length arrangement. Advantageous embodiments of the invention are set forth in the subclaims.

Compared with the prior art according to US Pat. Nos. 4,231,568 and 3 558 131 A, the invention has, among other things, the following essential differences:

· The preload can be adjusted continuously in contrast to US Pat. No. 3,558,131 A.

• By means of the electric hydraulic pump or the electric cylinder or the linear drive, the preload can be adjusted electrically, ie not mechanically.

· The preload weight is adjusted using a train scale mechanism 24 or a

Touch Panel PC displayed.

• The seat can be swiveled away so that a wheelchair user can also exercise on the equipment without leaving the wheelchair while exercising.

· The training weight can be automatically adjusted during the exercise.

For this purpose, a resistance adjustment is generated with the aid of the time and the position of the lever arm (incremental encoder), depending on the desired force curve.

• At the same time the training weight can be reduced automatically, if eg. B. the heart rate rises above the setpoint or the exercising person can not complete the exercise completely or the previously set

Time span has expired.

The electrical length adjustability is not apparent from the two mentioned writings. It also offers special advantages because the user can now adjust the length without leaving his training position. This is purely mechanical

Adjustments not readily the case. In electrical settings, a setting device can be guided by means of a cable to any point. This particular advantage is not apparent from the writings and is not suggested.

Further general explanation of the invention:

The combination of the spring preload system and the associated lever arm increases the "training weight" (the training force) up to the end of the exercise, resulting in greater safety, greater well-being and a lower risk of injury. The spring preloading system and the folding elements of the device are space-saving than known muscle training devices with weight systems. The new design makes it possible to train in a corner of the room. The required location and training area drops many times over others

Muscle exercise equipment.

With the aid of the spring preloading system, consisting of the spring assembly, lever arm, hydraulic cylinder and the hydraulic (hand) pump, it is possible to set the training weight to the nearest gram. The hydraulic pumps can be different, z. B. manually (hydraulic hand pump) or electrically driven.

embodiments

In the following, several embodiments of the invention will be described in more detail with reference to drawings. In all drawings, like reference numerals have the same meaning and therefore may be explained only once.

First embodiment

Figure 1 shows the entire muscle training device at rest. As you can see, the special space-saving design allows a location in a room corner. The seat arm (13), the spar (1) for the pulleys and the two rudder arms (10) can be easily folded into the interior of the unit, so that you need a site area of only 0.3 m ² . With the help of the new spring preloading system and a quick conversion of some components, it is possible to train all the back muscles in the smallest space. Other muscles such as biceps and triceps can also be trained on this device. At the same time, the method of the spring biasing system provides for an increasing workout weight during the exercise. The training weight can be adjusted with the help of the hydraulic system. Ropes (18) and pulleys (17) ensure that the training weight for the user from the end of the drawbar to the preload holder (2) or rudder lever (10) is available. Different seat assemblies (20) can optionally be plugged into the numerous seat mounts on the seat post (13) and adjusted by means of split pins (21) in height. This ensures the perfect, gentle sitting position.

For different training methods and roller guides are several sets of units, each with spring assemblies 8, 8a, receiving arms 7, 7a and

double-acting hydraulic cylinders 11, I Ia provided. Figure 2: The arrangement is at rest and shows all the essential components.

The spring assembly (8) is relaxed and the hydraulic cylinder (11) is extended. The pull lever (6) is at the bottom of the spring assembly in the starting position.

Figure 3: The spring assembly (8) is not biased and the arrangement can only be operated via the pull lever (6). Since the applied force due to the spring constant D is proportional to the distance traveled Fl, you can now train with uniformly increasing force. The full load thus occurs only at full deflection.

In Figure 4, the spring assembly (8) is biased. This is done by the

Hydraulic cylinder (11) is actuated by means of a hand pump. In this example, a preload of 100 mm is assumed. From the formulas of FIG. 3, at the same spring constant, a preload force FV of 5452 N results.

In FIG. 5, we initially have the same preload FV as in FIG. 4. Thus, an identical spring deflection of 100 mm is again achieved with the aid of the

Hydraulic cylinder assumed. The preload force is again 5452 N.

In order to bring the pull lever (6) in the position of Figure 5, the spring assembly is additionally stretched by 100 mm upwards. This results in the total force FG a value from the two individual forces Fl + F2 = 5452 N + 5452 N = 10904 N. The tensile force F2 can now be determined from the right-handed and left-handed torque.

Figure 6 shows the basic structure of the spring package, consisting of 2 x 5 individual springs.

FIG. 7 shows the two linear drives (52, 57)

Resistance generation. The linear actuator (57) is used for the pretensioning system. The other linear drive (52) adjusts the position of the spring assembly on the lever arm (53). Both systems with the associated sensors incremental encoder (63) and located in the linear actuators positioner (potentiometer) provide the automatic weight adjustment (resistance adjustment) during the exercise. It enables the realization of force curves (resistance curves) during training (exercise).

functionality

Step 1: The trainee chooses an exercise and adjusts the appropriate seat abutments (20) on the seat post (13) to his physique.

Step 2: He sets the weight to be trained with the help of the hydraulic system to his desired weight. This is done by the Zugfederpaket (8) of the

Hydraulic cylinder (11) is biased. Step 3: Now it is possible to perform the exercise in different ways with the help of the pull cable (18) and with the handle (23) at the end in a suitable sitting position. Mostly here the handle is pulled to different areas of the body. With the help of the Federvorspannsystems and the associated pull lever (6) is now no longer immediately the entire weight to be trained on, but only a small weight that increases in the exercise execution in the course of movement to the body to the end of the exercise on the previously set weight , With the help of a Zugwaagenmechanik (24), which is located in the pull cable (18) between the pull lever (6) and the handle (23), that is

To detect preload weight.

The unusual design and the special design, ensure an all-around space-saving device. Second Embodiment Component Description (FIGS. 8 and 9)

The roller 51 serves to adjust the spring assembly (bearing for the

Change in position). The first linear actuator 52 (24V) is responsible for the position adjustment of the spring assembly. The lever arm 53 stores the force for the

Release at the training element.

The spring packet receptacle 54 ensures the connection of the spring assembly to the mounted lever arm. The cover 55 provides the mechanical protection of the exerciser. The frame profile 56 gives the device its shape. The second linear actuator 57 (24V) is for the preload of the spring assembly. The tension spring 58 provides the necessary training resistance. The

Training element holder 59 ensures the connection of the carrier spar to the respective training element. On the support rail 60 of the respective seat is mounted mounted (seat can be swung away). In addition, the respective training element is stored on it. The seat mounts 61 are for mounting the respective seat.

The two pedestal bearings 62 absorb the shaft of the lever arm and ensure smooth rotation of the lever arm. The incremental encoder 63 passes the position of the lever arm to the controller.

The cable 64 transmits the force via rollers to the training element and provides for the upcoming training resistance on the training element.

In the series invention novel training devices force development and weight control make the usual iron weights with power and

Impact transmission via cable superfluous. With an electronically controlled form of weight adjustment, it is possible to realize linearly increasing weights during the exercise. In addition, with the help of the control software

Adjusting the training weight in the course of the exercise allows. These devices differ in technology, force control and optics fundamentally from the conventional sports and fitness equipment.

Overall, the introduction of this completely novel type of effect on devices with the possibility, in principle, each training completely individually controlled by computer and run by a training supervisor controllable, a sustainable innovation for targeted target areas market segments.

The core product consists of a novel device family, with the isokinetic physical exercises can be performed as a medical therapy or sports and fitness training.

This methodology was significantly improved by a special electronic, interacting control. This has proved to be more ideal

Possible use of these devices in the field of medical technology - preventive and rehabilitative - proven.

The configuration of the various device versions allows - similar to the equipment variants for car purchases - an individual device version configured to customer requirements. Here, by adding or omitting certain equipment modules, the performance, scope and price of each device can be varied. Thus, in the individual

Target groups of almost every device user in a targeted and price-effective manner.

These devices can easily be upgraded to other functionalities.

Another product area is using motion rails for the

Rehabilitation treatment of bone injuries covered. In this case, the isokinetic mechanism is built in miniaturized form for arm or leg splints in order to precisely match the medically indicated effort with the load limits of the injured limb.

Specific devices can be used for any sport, e.g. optimized rowing, whereby a realistic power curve can be implemented. A variant of the medical product line is designed especially for seniors to avoid injuries during training with a more porous bone structure and less resilient muscles.

Functional description of the devices

By means of a spring package consisting of a different number of

Tension springs - which are housed in the floor box - and a lever arm mounted, it is possible at the end of the lever arm by a rope or a chain

Training arm to move, the tensioned automatically and electronically controlled springs to the end of the training path. Thus, a - previously definable - training weight is achieved, which increases linearly during the exercise movement to the end of the movement. If now the spring package with the help of a biasing device stretched different lengths, which increases until the end of the exercise weight is increased.

This method of weight adjustment ensures that an increasing training weight can be set compared to conventional exercise equipment.

In addition, ligaments and muscles are gently guided over the entire training path until the maximum weight is reached. Even with fatigue of the exercising

Person during a training set can immediately feel the benefit of the rising and falling weight, as they are e.g. when raising the

Training bar (Latissimuszug) noticed a reduction in weight and thus achieved a safer training feeling. This minimizes the risk of injury and increases the motivation to train.

Back straightener: The very contemporary and compact design ensures an airy training environment. In addition, it is barrier-free, as well as wheelchair users

Possibility to train on these devices. This is done by turning away (arrow 65) of the training seat 66 to the seat 61 to the outside

(Figure 16).

Back stretcher in wheelchair mode

As an aid during the exercise, a specially adapted wheelchair having some special features, e.g. special adjustment of the

Seat, a very low backrest and special locking options. This makes it possible to create almost perfect training facilities even for people dependent on wheelchairs. All devices are available in different versions. These have

different equipment for different training variants. This also defines the application areas, e.g. medico-therapeutic or for sports and fitness. So the customer can decide which of the described functions he needs for his training facility.

The devices are characterized by a compact design, since they have no disturbing and unnecessary attachments. A set of training weights is not present and therefore gives a lower weight. This also ensures an unrestricted view of mirrors installed on the wall. These are necessary for self-control for a correct training process. For a comparison of correct posture and exercise performance, some equipment variants (with integrated screen) provide a training sequence recorded by a coach on video, in which the exercising person has the correct one

Training attitude has accepted. This video clip will appear whenever the training starts.

It is also possible to set up a personal comparison, with the video clip played and the training situation viewed in the mirror. Thus, the exercising person - or the supervising trainer - can react immediately in case of deviations and change posture or exercise weight level. As you know, many protracted sports injuries come from incorrectly executed

Training exercises.

In the premium equipment, the devices are individually adapted to the training person for an electronic, interactively functioning computer control

Weight allocation and exercise routine to program, and with a

Control terminal connected by the supervising coach to monitor and follow up.

A screen attached to the device can both record the recorded correct training sequence, play instructions of the trainer on headphones, speakers or flow chart, as well as conventional movies or music video clips (via headphones) for entertainment or distraction play. This allows a personnel-saving monitoring of exercisers or patients via the

Trainer control panel with the information to be retrieved individually about the respective training process - and the possible control of medical values such as pulse,

Muscle tension, respiratory rate or blood pressure - even multiple participants.

Alarm functions for sudden medical problems can also be programmed individually. This particular technology can be used in the medical-therapeutic field, especially for persons with limited movement or force exercise behavior. Due to the extremely gentle use of the technique, rehabilitation as well as preventive work can be carried out with the highest and most gentle methods for the patient.

This opens up a completely open and extreme in this market segment

receptive demand market. According to the opinion of the TU Chemnitz, the

scientific research work for medical training devices, there is a very good marketing prospects, since similarly functioning training devices are not yet available, but are urgently needed. The devices of the different equipment variants contain numerous

Application areas and functional levels.

The variety of training options described there is unique to the calculated offer price in the market of isokinetic devices and open up to each sports venue operator more customer groups and many innovative new forms of training.

In addition to the devices described above, which are to be assigned to the "hardware area", additional services such as the installation and final assembly of the devices at the device operator, instruction in the operation of the device and repair and maintenance work are also offered - even or under license become.

The development of specifically programmed control software and the creation of - also graphically animated - training programs are part of the range of services.

In addition, regular technical developments or software updates are offered on a regular basis.
