Description

Muscle-powered, moving fitness machine for full-body training.

Fitness machines of the usual design are generally installed in a fixed location in fitness studios or in the user's home. In addition, different individual machines are combined as complete stations for different muscle groups. Each individual machine also only specifies one direction of movement for training.

In addition, each individual muscle group to be trained (agonists) is only trained individually, i.e. without putting strain on its opposing muscle group (antagonists) by performing the movement in the opposite sequence.

So if you want to train all of a person's muscle groups, you have to use conventional fitness machines to invest a lot of mechanical and material effort. The energy used by the person training with conventional fitness machines also remains "unused", so to speak.

There have long been individual fitness machines or combinations of several machines that, although advertised otherwise, only train certain muscle groups, but never all of them.

Other "devices", known as bicycles or rowing boats, are used for locomotion, "use" the energy of the person exercising and thus also give the person exercising "fun while training in the fresh air", but also only put strain on a few individual muscle groups in the right way for training - for example, with a bicycle, the

Leg extension: when rowing, the arm flexors, the leg extensions and the back are stressed/trained.

There is also a "rowing bike" from the USA, which simply "transfers" the typical rowing movements to the road and is relatively complicated to handle because it requires balancing. This device also only trains agonists and only those that are strained when rowing in a boat.

In addition, only one person can usually train on each machine and station on conventional fitness machines; stimulating competition that is directly geared towards the relative strength of the person training is therefore almost impossible on just one machine.

problem

The invention specified in the protection claim is based on the problem of creating a fitness machine that uses the "training energy" used for propulsion in order to create the coveted "fun in the fresh air". To this end, the stimulating and directly comparable competition based on the relative strength and endurance of the trainees (such as in cycling races or rowing boat races) should be possible. In addition, the machine should be able to train ALL muscle groups of the human body with the least possible material WITHOUT time-consuming conversion work using the previously known movement sequences of strength training.

It is also important that the machine can be used by people of ALMOST ANY body size without modification.

The machine must be operated and controlled in such a way that the trainee can concentrate fully on his training even at full speed, WITHOUT having to practice balancing and that only brief instructions on steering and braking are required.

Likewise, the machine should train agonists AND antagonists in every single repetition (complete movement sequence, e.g. "lat pull" AND "press" or "bicep curl" AND "tricep curl") for each exercise.

A freewheel function must also be provided so that the user can, if necessary, roll the machine when going downhill or let it coast before stopping or during short breaks.

And for partial to complete braking or emergency stopping, the brake should be able to be operated effectively with little effort. In addition, the machine must be easy to partially dismantle and thus easy to transport and store in a space-saving manner.

It is precisely this complex of problems that is solved with the features listed in the protection claim, because this enables ...

. . that the machine can roll and stand on at least three wheels (like a tricycle) or four wheels (like a car) and with foot steering, controlled by a person sitting on it, full concentration on the strength exercises is guaranteed WITHOUT the trainee having to devote himself to balance,

. . that the physical effort of the person exercising serves to move them, "fun in the fresh air" is possible,

. . that achievable speed and range are not determined solely by muscle mass, but rather by the relative strength and endurance of the trainee, people of different heights and masses can compete with each other,

that the hydraulic cylinder is double-acting with a system of four check valves and a compensating tank, which always allows the hydraulic motor to rotate in the same direction with every piston movement, regardless of the direction and regardless of the stroke size, the alternating agonist-antagonist training is ensured in every exercise repetition, even for people of different body sizes,

that the hydraulic system just mentioned and described in more detail in the text and drawing below allows the hydraulic motor to rotate even when the piston of the hydraulic cylinder is not moved, the freewheel is secured to allow the machine to roll,

. . that the operation of a simple shut-off valve on the inlet or outlet of the hydraulic motor, which can be managed with little force, causes the motor to run more slowly or to come to a complete standstill due to the incompressibility of the hydraulic fluid, the machine can be safely braked with little effort

and thereby ..,

. . that the double-acting hydraulic cylinder with its base can be pivoted in the transverse axis of the vehicle and can be mounted at various positions within the machine itself by means of bolts and split pins as well as hydraulic quick-release fasteners, ANY force vector relevant for a whole-body strength training can be represented.

An advantageous embodiment of the invention is specified in claim 2:

The changeover valve, which short-circuits the two working chambers of the hydraulic cylinder completely or not at all depending on the operation, means that the motor is driven more or less quickly for the same working stroke of the cylinder. This operating principle is equivalent to an adjustable gear ratio, so that the machine - depending on the gradient of the route / wind resistance or training requirements - can be moved faster with more effort or slower with less effort.

The quick-release fasteners on the wheels and the foldable backrest mounted on the seat also make it easy to dismantle the machine, thus saving space and making it easier to transport. The short-circuit valve, which can be used to short-circuit the hydraulic motor if necessary, makes maneuvering easier, because the motor can be driven in both directions by hydraulic short-circuiting.

The machine can therefore be moved (maneuvered) forwards and backwards.

The springy, shock-absorbing suspension of the wheels also improves the ride and therefore the training comfort.

A pelvic belt is also attached to the seat so that the user can train the latissimus dorsi (during pull-up-like movements) according to his or her strength without having to limit the use of strength to his or her body weight alone.

And foot straps are mounted on the pedals so that the user can easily use his leg flexor muscles during rowing movements.

The handle on the piston rod of the hydraulic cylinder can be mounted in different bent versions and different lengths to meet different training requirements. The unused versions of the handle are always carried along, attached to clamps on the frame of the machine.

From all the advantages mentioned, the machine has various applications:

Endurance training for all athletes, training variety for every competitive athlete, disabled sports machine, convalescent sports machine without trimming for maximum strength, alternative fitness machine, new type of racing device... etc.

Embodiments of the invention: Training or exercise examples

1.Example exercise: Hydraulic cylinder mounted near the feet, pointing diagonally upwards and backwards. Seat mounted on rollers
The trainee performs rowing training. In one direction of movement, he pulls on the handle of the hydraulic cylinder, supports himself with his legs on the pedals in order to push the rolling seat backwards and moves his upper body backwards (training effect on these muscles: arm flexors, entire back, leg extensors).

In the counter movement, he presses the handle, moves his upper body forward and pulls the seat forward using his leg flexor muscles (training effect on these muscles: arm extensors, chest, lower abdomen, leg flexors).

2.Exercise example: Hydraulic cylinder mounted near the feet. Pointed diagonally backwards and upwards. Seat locked

Depending on the grip (instep or comb grip), the trainee trains the outer or inner parts of the biceps or triceps.

When moving in one direction, he pulls on the handle of the hydraulic cylinder and supports himself with his legs on the pedals. (Training effect on these muscles: especially arm flexors, less so back and leg extensors).

During the counter movement he presses the handle (training effect on these muscles: especially arm extensors, less chest and lower abdomen as well as leg flexors).

3 .Exercise example: Hydraulic cylinder mounted near the seat, almost vertically aligned. The trainee trains in a similar way to pull-ups and presses.

In one direction of movement, he pulls on the handle of the hydraulic cylinder, thus pushing the piston into the cylinder, while being held to the seat with the lap belt (training effect on these muscles: arm flexors and especially latissimus).

During the counter movement, he presses the handle, thus pulling the piston out of the cylinder (training effect on these muscles: arm extensors and especially the front and upper shoulder muscles) .

4.Exercise example: Hydraulic cylinder mounted near the seat, directed diagonally forward. The trainee trains in a similar way to the so-called incline bench pull and bench press.

In one direction of movement, he pulls on the handle of the hydraulic cylinder, thus pushing the piston into the cylinder, while being held to the seat with the pelvic belt (training effect on these muscles: arm flexors and especially latissimus and lower abdomen).

During the counter movement, he presses the handle, thus pulling the piston out of the cylinder (training effect on these muscles: arm extensors and especially chest and front shoulder muscles) .

Further detailed exercise examples: Depending on the inclination and mounting position of the hydraulic cylinder and the handle used, examples 1 to 4 can be modified and refined in the exercise execution.

Due to the freewheel effect of the machine, the trainee can (if he wants) also train only agonists by actively and powerfully performing one direction of movement (with propulsion effect), but then slowly returning the handle to the starting position with the opposite movement.

Examples of the effect of the hydraulic system:

1. Example: Effect between hydraulic cylinder - check valve - hydraulic motor

1.1. Effect of the drive, changeover valve (UV) is in the "slow" position, motor short-circuit valve (KV) is closed, shut-off valve for the brake (AVB) is open. Drawing 2.1
The piston of the hydraulic cylinder (3) moves towards the outlet of volume no. 1 (Voll). The hydraulic fluid (hereinafter referred to as "HyFl") partially flows into Vol2. Because Vol2 is smaller than Voll, the "remainder" of Voll flows via the check valve (RV4) to the hydraulic motor (HyM/7). There is no flow through RV3 and RVl because they are currently blocked.

HyM is driven and thus drives the fitness machine forward. The HyFl flows further via open AVB and RV2 to the expansion tank (ABh).

There is no flow through RV3 and RVl because the pressure after HyM is much lower, because atmospheric pressure prevails in Abh.

Now the piston of the hydraulic cylinder (3) moves in the direction of the outlet of Vol2. The HyFl partially flows into Voll. Because Voll is larger than Vol2, the "remainder" sucked in by Voll flows from ABh via RVl to HyM. There is no flow through RV2 and RV4 because they are currently blocked.

HyM is driven and thus drives the fitness machine forward. The HyFl flows further via open AVB and RV3 to Voll.

Utility model application. rsroir·Aj ² CtH*·!Köhler, Bahnhofstr. 21, 2 93Ö^\in§ ^l erf'" TeIW 05143-1459, Fax: 2821, page 11

There is no flow through RV4 and RV2 because the pressure after HyM is much lower due to the suction from Voll, as atmospheric pressure always prevails in Abh.

1.2. Effect of the freewheel, changeover valve (UV) is in the "slow" position. Motor short-circuit valve (KV) is closed, shut-off valve for the brake (AVB) is open. Drawing 2.1 The piston of the hydraulic cylinder (3) is not moved (let the machine roll). HyM sucks in HyFl via RVl and RV4 and "pumps" it back to RVl and RV4 via the open AVB and both check valves RV2 and RV3, etc.

Because the amount of HyFl is pumped back to the suction point in the same way that it is sucked in, the volumes in ABh and V0II/V0I2 do not change. So HyM does not move the piston of HyZ. Nor does HyFl flow out of or into ABh.

2.1. Effect of the gear-like transmission, changeover valve (UV) is in the "slow" position, engine short-circuit valve (KV) is closed, shut-off valve for the brake (AVB) is open, drawing 2.1

The effect of the check valves RVl to RV4 in connection with HyM/7 and ABh is described under point 1.1. A characteristic of the position UV=slow is that HyM is only driven by the differential volume (full - V0I2), because the two volumes are "short-circuited" via the supply line to UV.

Because the differential volume is smaller than full, a certain stroke of the piston moves HyM and

Utility model application LclV^Ö' $

Bahnhofstr. 21, 293Ö8 'wins'eri*' Te*!*.**:* 05143-1459, Fax: 2821, Page 12

This makes the machine relatively slower than with the UV position reversed.

2.2. Effect of the gear-like transmission, changeover valve (UV) is in the "fast" position, engine short-circuit valve (KV) is closed, brake shut-off valve (AVB) is open. Drawing 2.2

The effect of the check valves RVl to RV4 in connection with HyM and ABh is described under point l.1. A characteristic of the "UV=fast" position is that HyM/7 is now driven by the entire volume, because the short circuit of the two volumes via the supply line to UV is now ineffective. The amount of HyFl in ABh is just as large as in the "UV=longitudinal" position, because Vol2 sucks in the "remainder" of the HyFl.

Because the volume Voll flowing through the HyM is now larger than the difference volume (Voll-Vol2) of the previous case, a certain stroke of the piston moves the hydraulic motor (7) and therefore the machine relatively faster than in the UV=slow position.

3. Effect of the short-circuit valve (KV), position of the changeover valve (UV) is irrelevant. Position of the shut-off valve for the brake (AVB) is irrelevant. Drawing 2.2 or 2.1

When the KV is closed (= position for normal training operation), HyM can only be moved in one direction due to the freewheel. In the opposite direction, all four check valves RVl to RV4 are blocked. This can be a hindrance when maneuvering the machine. If, however, the KV is open for maneuvering purposes, the hydraulic motor (HyM/7) can move in both possible directions.

directions without moving the hydraulic cylinder and without changing the volume in ABh.

4. Effect of the shut-off valve for braking AVB. Position of the changeover valve (UV) does not matter. Short-circuit valve (KV) is closed Drawing 2.2 or 2.1

Due to the incompressibility of the HyFl, HyM is in place when AVB is completely closed. If AVB is fully opened, however, travel mode and freewheeling function.

When AVB is in the intermediate position, HyM is partially slowed down by the deliberately induced flow losses.

5. Use of flexible cables (FL) and quick-release fasteners (STl) and (ST2)

In previous versions (see claims, advantageous design) and shown in drawing 1, the hydraulic cylinder must be able to be mounted at various points on the machine and pivoted. Flexible hydraulic lines are used for pivoting and the quick-release fasteners (STl and ST2) are used for quick conversion for different training requirements.
