Definitions

  • the invention relates to a device for body and muscle training with a device for adapting the load to the exercise sequence, consisting of a rotatably mounted cam that can be rotated with the exercise, which is connected to the counterforce by a cable or chain hoist Active connection is established.
  • gravity or spring forces are usually used to strain the muscles to be trained.
  • Gravity has a vertical direction; the direction of the spring forces to be overcome depends on the installation position of the springs in the training device.
  • deflection devices In order to change these fixed directions and to adapt them to the movement of the body part to be trained, it is known to use deflection devices. In the simplest case, these consist of deflection rollers over which a cable is guided. It is not possible to adapt the opposing forces to a specific exercise sequence.
  • a cam (“D-shaped cam”) is provided, which is moved by the body part to be trained and to which a cable under the influence of weights is attached. Due to the different distance that the point of application of the forces, i.e. the load point of the rope on the cam, during its rotation from the axis of rotation, the load is different.
  • the respective force profile depends on the shape of the periphery of the D-shaped cam.
  • a disadvantage of the described embodiments is that the force profile of the known devices cannot be varied in a simple manner.
  • a varied variation of the course of forces is necessary for a variety of reasons, and not only to adapt the load to the different anatomical relationships of different exercising people, but also for so-called subjective adaptation, that is, to adapt the course of forces to the subjective abilities of the trainee .
  • different training goals require different strength profiles.
  • the process of loading a muscle is e.g. different, depending on whether the muscle should be trained for endurance, growth, maximum strength, etc.
  • the present invention has for its object to improve a device for body and muscle training of the type mentioned in such a way that a variation of the force profile or the load sequence is possible in a simple manner.
  • this object is achieved in that the axis of rotation of the cam disc determining the load sequence is adjustable in the rotating plane. Even a slight shift in the axis of rotation causes a change in the load sequence due to the changed distance ratios of the periphery of the disk to the pivot point.
  • the invention makes it possible, for example, to set different load variations during a certain training session without having to take longer breaks for changing the force profile.
  • Figures 1 and 3 to 6 each show an essentially D-shaped cam 1, the approximately round periphery of which has a groove 2.
  • the groove 2 is used to receive a cable or chain hoist 3 (here a chain), which is attached at its end shown at 4 to the cam plate 1 and with its end, not shown, is in operative connection with a counterforce (weight, spring).
  • Groove 2 and chain hoist 3 are only shown in Figures 1 and 6. All cams 1 each have a central opening 5. In the area of this opening 5, means are arranged for holding a shaft, not shown, which determines the axis of rotation of the disk 1 during the training process.
  • an articulated arm 6 which passes through the inner opening 5 of the D-shaped cam disk 1 and is equipped with an opening 7 for the shaft determining the axis of rotation 8. With its one end 9, the articulated arm 6 is pivotally supported about the axis 10 approximately in the middle of the rounded periphery of the D-shaped disk 1.
  • the other end of the articulated arm 6 is assigned, on the opposite side of the D-shaped disc 1, a guide 12 lying concentrically to the axis of rotation 10, on which the free end 11 of the articulated arm 6 is mounted so that it can be moved and locked.
  • the guide 12 has recesses 13 in its outer region, into which a pin 15, which is under the influence of a compression spring 14 and is held on the face end at the free end 11 of the articulated arm 6, can be inserted.
  • FIG. 2 shows a diagram in which the load (force F) as a function of the position of the cam disk 1 is shown for three different positions of the articulated arm 6 in the exemplary embodiment according to FIG. 1.
  • the load force F
  • Curve a the load goes through a maximum.
  • curve b continuously decreasing
  • Curve c continuously decreasing
  • an articulated lever 6 which can be pivoted about the axis 10 and in whose opening 7 the shaft (not shown) engages, is also provided.
  • the free end 11 of the Articulated arm 6 equipped with a rotatably mounted adapter 17, which has a threaded bore 18 perpendicular to the axis of rotation 7.
  • the threaded bore 18 is assigned an adjusting nut 19 which is held on the D-shaped disk itself by means of the threaded sleeve 21 so as to be rotatable about the axis 22.
  • the shaft 7 receiving opening is arranged in a fitting piece 25 which is inserted in a linearly displaceable manner in the opening 5 of the D-shaped disk 1 and also has a threaded bore 18.
  • the edges 26 and 27 which delimit the opening 5 and extend approximately along the D-shaped disc are designed as rails which accommodate the adapter 25.
  • the displacement of the adapter 25 is again carried out with an adjusting nut 19 which is held on the D-shaped disc by means of the threaded sleeve 21.
  • the axis of rotation of the system is adjusted by turning the head 23 of the adjusting nut 19.
  • Figure 5 shows an embodiment in which the opening 5 in the D-shaped disc 1 is circular.
  • a ball bearing 31 is inserted, the outer ring 32 is fixedly connected to the D-shaped disc 1 and the inner ring 33 carries a rotatable disc 34.
  • the opening 7 for the mounting of the shaft, not shown, is arranged eccentrically.
  • a further circular disk 30 is provided, which in turn is supported in the disk 34 via a ball bearing 35.
  • the rotation axis 8 is adjusted by rotating the disk 34.
  • the clamping levers 36 and 37 serve to lock the disks 30 and 34 in different positions with different loading processes.
  • the articulated arm 6 itself is provided with an adjustment device, generally designated 41, which corresponds to the adjustment device according to FIG. 1.
  • the articulated arm 6 has an opening 42 with a fitting piece 44 arranged and displaceable therein by means of the adjusting nut 43, in which the opening 7 is arranged for receiving the shaft.
  • the load sequences which can be adjusted solely by adjusting the axis of rotation 8 with the aid of the adapter 44 are shown in the diagram according to FIG.
  • the curves run through a maximum or minimum, the vertex of which is adjustable.
  • the axis of rotation 8 can be adjusted as described for FIGS. 1 and 2, so that there is a particular variety of adjustable load sequences.
