Definitions
- the invention relates to an ergometer, preferably a bicycle ergometer, with a pedal arrangement mounted in a frame and an adjustable braking device, the two pedals of the pedal arrangement being independent of one another, with the exclusion of power transmission from one pedal to the other are.
- Bicycle ergometers have recently found a wide range of applications. So these are in addition to private use both in medicine, in particular in sports medicine for performance diagnostics, as well as for checking the Training progress used in high-performance sports. Another possible application arises in rehabilitation, for example in the event of an accident or Stroke patients.
- DE 36 03 853 A1 describes a bicycle ergometer with a Pedal arrangement has become known, which is an adjustable braking device and has a display instrument for the braking torque.
- a display instrument for the braking torque In the area of handlebar-like Handles is arranged on a panel, which is a pointer instrument for the torque and the speed.
- the user of the ergometer receives information on the one hand about what to overcome the set Braking force required torque as well as the respectively achieved Rotational speed.
- an ergometer is known from DE 42 27 586 A1, which can be found and training the optimal movement.
- the device can be constructive and destructive levels of force that a cyclist uses on the pedals releases, be recorded in real time and under real training conditions.
- the elastic deformations relevant to the pedal lever as well Deformation of handlebar and seat post by suitably arranging strain gauges selectively and independently recorded. From the won The cyclist's complete movement sequence can be determined using data and be optimized, which means force components that are moving forward are implemented, maximized and power components that are not in Forward movement can be implemented because it is static, for example Generate counterforce, be minimized.
- the device is disadvantageous Relatively complex, since up to four possible elastic deformations per pedal lever (Bend in the direction of rotation, bend perpendicular to it, elongation in the longitudinal direction of the pedal lever, torsion about the longitudinal axis of the pedal lever) separately and must be recorded and evaluated independently of one another.
- Another class of bicycle ergometers is used in medical diagnostics to determine the aerobic / anaerobic threshold of a patient, whereby the performance is usually increased gradually and different patient data such as heart rate, O 2 and CO 2 content of the breathing air etc. are determined .
- Such ergometers are known for example from US 4,463,764 A and US 5,782,772 A.
- the above devices are not suitable differences in the pedaling behavior of a subject's left and right legs if possible unaffected by disturbances and with high resolution within one To hold the crank rotation.
- a training device is known from WO 97/26948 A1, which is equipped with an in a frame mounted pedal assembly and an adjustable braking device is equipped, with both pedals of the pedal arrangement independent from each other, excluding power transmission from a pedal to others are stored.
- the known device also has a coupling device for the two pedals that can be moved independently of each other the training facility as a conventional bicycle ergometer with a 180 ° geometry for the two pedal arrangements can be operated.
- the Training device has two gear motors, which are used to adjust the braking force serve, the tension of a brake band is changed, which as band brakes on the brake disc of the left or right pedal arrangement acts.
- WO 99/62600 also shows A1 a pedal arrangement, the pedals have no common axis.
- the object of the invention is based on an ergometer of the aforementioned Kind of showing improvements that allow the torque curve each crank or leg separately with high resolution inside a crank rotation and the use of the ergometer in the area improve rehabilitation.
- each of the two pedals has one in its Power adjustable auxiliary motor is switchable.
- There is also one for each pedal separate braking device is provided, the braking force of which is independent of one another is adjustable and preferably attacks the flywheels of the ergometer Due to the complete mechanical separation of the power flow of both pedals their torque curve can be independent of the crank angle recorded from each other and after processing in a computer unit on a Display device in the field of vision of the exercising person or a patient in transferred to rehabilitation.
- each pedal is a torque sensor and / or a speed sensor, which with a computer unit including a display device, preferably a monitor, communicates.
- a computer unit including a display device, preferably a monitor.
- a torque or force / angle curve of the respective can be displayed on the monitor Represent leg.
- the driver can use this feedback system directly and arbitrarily influence its turning behavior in order to reduce side differences and consciously work on its "bilateralism".
- each of the two auxiliary motors can have an anti-spasm control which occur when a sudden change in resistance occurs can be activated automatically.
- a patient uses an ergometer, which one pedaling is assisted by an auxiliary motor, it is advantageous if the engine when spasms occur (suddenly occurring, greatly inflated Muscle tone) switches off or the direction of rotation changes. This can prevent that the spastic extremity is violently moved by the auxiliary motor becomes.
- the force separation in the crank mechanism of the ergometer can be according to one Embodiment variants of the invention can be produced in that one of the Pedals a crank axle with a tubular extension and the other pedal has a crank axis with a cylindrical extension, the cylindrical Extension is rotatably mounted in the tubular extension.
- the two extensions can be used as a conventional bicycle ergometer have aligned radial holes, by inserting a fixing screw in the radial bores the pedal arrangement in a 180 ° geometry is fixable.
- the ergometer shown schematically in FIG. 1 has one in a frame 1 mounted pedal assembly 2, which via a chain drive 3 on two separately mounted flywheels 4 acts with a braking device 5, the Braking force is adjustable independently.
- the regulation of the braking force can be mechanically or controlled by the in a manner not shown Computer unit 6 electromechanically, for example on the principle of an eddy current brake respectively.
- the two pedals 7 and 8 of the pedal arrangement 2 are independently of each other - excluding power transmission from the pedal 7 to pedal 8 - stored in frame 1.
- On the crank axes 7 ', 8' of each pedal 7, 8 is a torque sensor 9, which with the computer unit 6 in Connection is established.
- the computer unit 6 stands with a display device 10, preferably a monitor, in connection, which is in the visual field of the user is arranged.
- the computing unit and the monitor can also become one Unit summarized and in the area of the handlebar-like handles of the Ergometers can be arranged.
- a speed sensor can be provided on each crank axis 7 ', 8' 11 may be arranged.
- each of the two pedals is 7 and 8 the output of an auxiliary motor 12 which can be regulated in terms of its output, the movement of the extremity affected by the stroke by the auxiliary motor 12 is supported.
- FIG. 2 shows a possible embodiment variant of a bottom bracket unit of the ergometer, in which one of the pedals has a crank axis 7 'with a tubular Extension 13 and the other pedal a crank axis 8 'with a cylindrical Has extension 14, the cylindrical extension 14 in the tubular extension 13 is rotatably mounted.
- the crank axis 7 ' is mounted twice in the bearing housing 15 (see bearings 16, 17), the crank axis 8 'is through the bearing 18 as well by the bearing 18 ', which is only indicated by dashed lines, is also stored twice, as a result of which a compact design is realized.
- Between the two bearings 16 and 17 a spacer sleeve 26 is arranged between the two bearings 16 and 17 .
- the chainring 19 is on both sides with the help of an adapter plate 20 a flange 21 of the crank axis 7 'or 8' attached.
- the chain fender is marked with 22 on both sides.
- the torque sensor 9 is, for example from a torsion ring attached to the crank axles 7 'or 8' 23, which with a preferably attached to the chain guard 22 data collector 24 cooperates.
- the outgoing from the data collector 24 to the computer unit 6 leading signal line is designated 25.
