Definitions

  • the invention relates to a training device, namely an elliptical or crosstrainer with two pedals, which are mounted on a respective pedal bar, the pedal bars are connected to the rear ends articulated with a respective pedal crank.
  • the pedal cranks are rotatably arranged about an axis.
  • Such training devices are known for example from the utility model publication with the publication number DE 201 00 276 U1. In addition, such training devices from various suppliers, including the applicant, manufactured and distributed.
  • the training device disclosed in publication DE 201 00 267 U1 has two pedals firmly connected to the associated pedal bars. A user of the exerciser standing on the pedals of the exerciser performs any movement that the pedal bars make. The movement is essentially elliptical, which is where the term elliptical trainer comes from.
  • the exercise device disclosed in the document has a possibility to vary depending on the height of the user's different step lengths, d. H. adjust elliptical movements of different sizes. For smaller individuals with a smaller stride length, an ellipse can be set with smaller radiuses, and for larger persons with longer stride length, an ellipse with a larger radius can be set.
  • the elliptical movement of the feet which is transmitted to the musculoskeletal system on the trunk of the body, comes close to a natural running movement, but it does not correspond to 100% natural movement. Especially for first-time users, the movement on such a training device is therefore unfamiliar.
  • the invention has for its object to allow the practitioner a more natural movement, in particular a more natural movement of the legs and hips as in the previously known Crosstrainern.
  • the pedals are slidably mounted on the pedal bars.
  • the pedals are slidably mounted on the pedal bars so that they are moved forward and backward while using the exercise machine.
  • the pedals are so displaced during operation on the pedal bars and do not perform one-to-one movement of the pedal bars. The user is thereby enabled a more natural movement.
  • the pedals are pivotally connected to a push rod, said push rods can be hingedly connected to a push rod crank.
  • These push rod cranks are preferably arranged rotatably about the same axis about which the pedal cranks are already rotatably arranged.
  • each pedal is pushed during operation of the training device on the pedal rod back and forth. The pedals thus carry out a defined movement on the pedal bars. These movements of the pedals make the ellipse flatter overall, which corresponds to a more natural movement.
  • the distances between the points of attack of the push rods on the push rod cranks and the axis can be adjustable. This allows adaptation to persons with different stride lengths.
  • the pedal cranks and / or the push rod cranks can be wholly or partially formed by circular discs.
  • the points of attack of the pedal bars on the pedal cranks and optionally the points of application of the push rods on the push rod cranks are preferably in a plane which also contains the axis about which the pedal cranks and the push rod cranks rotate.
  • the pedal bars of a training device can be hingedly connected with front ends with a pedal lever.
  • the pedal levers in turn can be pivotally mounted in a respective front bearing.
  • this front bearing is height adjustable mounted on a front frame part of the training device. Due to the height adjustability of the front bearing, the normally substantially horizontally oriented ellipse can be tilted upwards or downwards. Such a tendency can give a user the feeling that he is moving uphill or downhill.
  • the exercise device with a height-adjustable front bearing may have special adjustment means for adjusting the height of the front bearing.
  • These adjusting means may comprise a drive, in particular an electric motor, so that the adjustment of the front bearing does not have to be done by hand.
  • the means for adjusting advantageously comprise elements for converting a rotational movement into a linear movement.
  • Such elements may include a spindle on which a nut may be rotatably mounted.
  • pedal levers handles are preferably attached or formed, to which the user can put his hands during the exercises.
  • the crosstrainer shown in Figures 1 to 5 has a frame with a frame base 1 a and a frame front part 1b.
  • the frame is essentially made by two spaced-apart hollow profiles.
  • the hollow profiles are guided largely parallel to one another, in particular in the region of the frame front part 1b.
  • the hollow profiles are angled, so that they lie directly against each other in this area.
  • first webs 1 c The upwardly projecting ends of the hollow profiles which form the front frame part 1 b are interconnected via first webs 1 c. These first lands 1c are made of flat steel pieces.
  • first lands 1c are made of flat steel pieces.
  • the two hollow sections in the region of the frame front part 1 b are connected to each other via a second web 1 d of a hollow profile.
  • an electric motor 5 is attached at this web 1 d, which is mounted below the first two webs 1 c.
  • This electric motor 5 drives a spindle element 4 whose length can be changed by the electric motor 5. With its lower end, the spindle element is attached to a fitting 2, the firmly connected to the web 1 d.
  • the upper end of the spindle member 4 is connected to a fitting 3 which is fixed to a cross member 7. This Traverse 7 is slidably mounted on the sliding tubes 6 between the first webs 1c.
  • the height of the cross-beam 7 can be changed.
  • struts 7a are firmly attached, which are height adjustable together with the crossbeam 7.
  • two front bearings 8 are provided.
  • each a pedal lever 9 is pivotally mounted. The pedal levers 9 extend both below the front bearings 8 and above the bearings 8, wherein the upper ends of the pedal levers 9 form handles 10.
  • the lower ends of the pedal lever 9 are pivotally connected via a bearing 11 with front ends of pedal bars 12.
  • the rear ends of the pedal bars 12 are connected via bearings made of bearing bushes 12a and bearing journals 20 connected to pedal cranks 21a, 21b, wherein the pedal crank 21a is formed by a circular disc 21a.
  • the two pedal cranks 21a, 21b are rotatable about a common axis A.
  • the points of attack of the pedal bars 12 on the pedal cranks 21a, 21b are provided at the same distance from the axis A. Relative to the axis A, the points of attack are diametrically opposed.
  • a pedal crank designed as a flywheel flywheel 24 is driven from designed as a circular disk 21 .
  • a dental or V-belt 23 is placed over the circular disc 21a.
  • This belt drives the flywheel 24 with the interposition of a gearbox.
  • a housing 25 is provided in which various electrical Components, for example, an eddy current brake, various sensors and more are housed.
  • pedals 13 On the pedal bars 12 guide elements 13 are provided. On these guide elements 14 pedals 13 can be moved in the direction of extension of the pedal rods 12. On these pedals is the practitioner who uses the elliptical machine.
  • the pedals 13 are connected via bearings 15 to a first end of a push rod 16.
  • the push rods 16 are connected at their second end in each case via a bearing 17 with push rod cranks 19.
  • the push rod cranks 19 are fixedly connected to the bearing pin 20 to which the push rod cranks 12 engage with their bearing bushes 12a.
  • These push rod cranks 19, which are also designed as circular discs, as well as the pedal cranks 21a, 21b are rotatable about the axis A.
  • the points of attack of the push rods 16 on the push rod cranks 19 are diametrically opposite each other and in a plane E containing both the points of attack of the push rods 16 on the push rod cranks 19, the points of attack of the pedal bars on the pedal cranks 21a, 21b and the axis A.
  • the push rod cranks 19, the bearing pin 20, the pedal cranks 21a, 21b and a not shown, the pedal cranks 21a and 21b interconnecting shaft are rigidly connected together and form a multi-stepped crankshaft.
  • the inclination of the pedals 13 can be changed. If the front bearing 8 is raised, the exerciser may feel that he has to move uphill. By lowering the front Bearing 8, the counterpart can be achieved; The practitioner can be given the feeling of moving downhill.
  • connection at the second ends of the push rods 16 and the push rod cranks 19 is detachable.
  • the point of application of the second ends of the push rods 16, d. H. the bearings 17 can be radially displaced or offset on a line E.
  • 19 holes 18 are provided on each of the push rod cranks, in which a coupling element of the bearing 17 can engage.
