Definitions
- the invention relates to a treadmill device with at least one endless belt having a multiplicity of tread lamellae, which is guided around two deflecting rollers with parallel axes arranged one behind the other, the deflecting rollers being smooth in the area of contact with the belt and the at least one belt being designed as a flat belt, according to the preamble of claim 1.
- a treadmill device for physical exercise in which an endless toothed belt is guided around two parallel deflection pulleys arranged one behind the other.
- This toothed belt engages with corresponding toothed rings on the deflection rollers and can be driven by one or both deflection rollers.
- a large number of tread slats are attached to the toothed belt and serve as a running surface between the deflection rollers.
- the tread lamellas are additionally supported by a support roller arrangement (see FIG. 3 of the published patent application DE 2503 118 B2).
- toothed pulleys and toothed belts creates an unpleasant loud noise that is perceived as annoying during operation.
- great wear can be expected in the area of the teeth of the toothed belt.
- DE 42 38252 C2 describes a treadmill device in which the force transmission takes place essentially through a smooth part of the respective deflection roller on a smooth part of the endless belt.
- the respective deflection roller also has a toothed ring section which engages with an area of the belt which is toothed (see FIG. 2 of the mentioned patent DE 42 38252 C2). Since the power transmission takes place essentially over the smooth part of the deflection rollers and the sliding belt part of the endless belt, the noise development during operation is reduced.
- the object of the invention is to provide a treadmill device which enables operation to be as quiet as possible, the tread slat movement being stabilized in such a way that slippage of the belt unit with respect to the deflection roller is prevented and the arrangement is inexpensive and is reliable.
- each tread lamella has at least one engagement element projecting from the underside of the tread lamella, and at least two stabilizers are provided which are connected in a rotationally fixed manner to the deflection roller, such a stabilizer being in engagement with an engagement element on the underside of a tread lamella when the circumferential rich of the deflection roller, which rotates synchronously with the stabilizer, is in contact with the at least one belt and at least one stabilizer is in engagement with an engaging element at all times.
- the force is transmitted without interlocking timing belts / rings. Any slippage that may occur is prevented by the presence of stabilizers. At least one of these stabilizers is always in engagement with an engagement element.
- the stabilizers are non-rotatably connected to the guide roller, 100% reproduction of the speed of the treadmill in accordance with the guide rollers is guaranteed in this way. As there is no need for sprockets and belts, low-noise operation is guaranteed.
- the deflecting roller comprises at least two deflecting pulleys which are fixedly connected to a deflecting shaft, at least two corresponding belts being provided which are guided on the at least two deflecting pulleys, the at least one engagement element projecting from the underside of a tread lamella in each case between the belts and the at least two stabilizers are arranged between the deflection disks.
- Such an arrangement reduces the material expenditure of the treadmill device and allows a compact arrangement of the stabilizers.
- the tread lamellae can have a T-shaped cross section in the area between the belts, the lower web of this T being the engagement element.
- the engagement elements thus fulfill the function of support and represent corresponding engagement surfaces.
- the stabilizers extend radially with a length such that they can come into engagement with the engagement elements of the tread lamellae.
- At least four stabilizers are provided, two of which are spaced apart from one another with the same angular position with respect to the axis of the deflection rollers.
- the stabilizers extend from a deflection disc parallel to the deflection shaft on a radius of the deflection disc, which enables the stabilizers to engage with the engagement elements on the tread lamellae.
- This embodiment enables a further reduction in material and weight.
- one stabilizer on one deflection disk is opposite a second stabilizer on the other deflection disk.
- Such an arrangement enables a compact structure without the stabilizers being visible from the outside.
- the deflection disks can be connected to one another by the stabilizers.
- the stabilizers in the area of engagement with the engagement elements on the underside of the tread lamellae consist of elastic material or have an elastic coating. It is also advantageous if the engagement elements have a surface made of elastic material on the underside of the tread lamellae. These measures serve to further reduce noise.
- the engagement area of the stabilizers can advantageously be equipped with an extent in the circumferential direction of the deflection roller which essentially corresponds to the distance between two engagement elements of two adjacent tread plates when these two tread plates are located on the deflection roller.
- Such a configuration ensures stabilization of the treadmill movement in both directions and enables even more precise operation.
- the stabilizers are arranged in pairs, the two stabilizers of a pair being arranged in opposite positions with respect to the axis of the deflection roller.
- Figure 2 is a partial sectional view of the arrangement in Figure 1 along the line A-A;
- FIG. 3 shows the deflection area of a treadmill device according to the second embodiment of the invention
- Figure 4 shows a partial section of the arrangement of Figure 3 along the line B-B and
- FIG. 5 shows another embodiment of the present invention.
- FIG. 2 shows a partial sectional view of the deflection area of a treadmill device according to the invention. Corresponding to a section along AA in FIG. 1.
- An endless belt 2 runs around the deflection roller 3. Only one deflection roller is shown. The belt runs over two such deflection rollers, which are arranged one behind the other with parallel axes.
- the deflection roller 3 runs on a shaft 4.
- a large number of tread slats 5 are attached to the belt 2, which can be covered with a coating 1 which is impact-resistant. dernd can be formed, for example made of rubber.
- the individual tread slats are equipped with a T-shaped cross section.
- FIG. 2 does not show all of the tread slats on the belt.
- FIG. 1 shows the deflection area of a treadmill device according to the invention perpendicular to the axis of a deflection roller. Identical elements are identified by the same reference symbols.
- the deflection roller 3 consists of deflection disks 3a and 3b, which are firmly connected to a deflection shaft 4.
- a flat belt 2 runs on each of the deflection disks 3a, 3b and is driven by the deflection disks.
- the foot plates 5 are fastened to this band 2 with fastening screws 7.
- the webs 6, which serve as an engagement element, are formed only between the belt 2 or the deflection pulleys 3a, 3b. If the deflection shaft 4 is driven, the deflection disks 3a, 3b rotate and drive the tread plates 5 via the belt 2.
- stabilizers 8 are attached to the deflecting shaft 4 and extend in the radial direction away from the deflecting shaft 4.
- the length of these stabilizers 8 is such that they can engage with the downwardly extending engagement elements 6 of the tread slats 5.
- the stabilizers are made of elastic material or have an elastic coating so that the intervention is as quiet as possible.
- the engaging elements 6 of the tread slats 5 can be covered with elastic material.
- the engagement areas 9 of the stabilizers 8 have such an extent in the circumferential direction that they fit exactly between two engagement elements 6 of two adjacent tread plates 5. An optimal alignment of the tread slats 5 is guaranteed.
- the engaging stabilizers 8 with the engagement areas 9 prevent the flat belt 2 from slipping on the deflection roller 3, since the stabilizers 8 are connected to the deflection shaft 4 in a rotationally fixed manner.
- two stabilizers 8 are arranged opposite one another, so that at least one stabilizer is always in engagement with the tread lamellae.
- it can improve Effectiveness any number of stabilizers with different angular positions can be provided.
- two stabilizer units are shown along the shaft 4 with the same angular position in the embodiment shown. This ensures an optimal straight direction of the tread lamellae 5. If, on the other hand, only one stabilizer unit is provided along the shaft 4, which can consist of several stabilizers 8 with different angular positions, the individual stabilizers 8 must have such a width that an optimal straight direction of the Slats 5 is guaranteed.
- any slip that may occur between the belt 2 and the deflection roller 3 is prevented by the engagement of the stabilizers 8.
- the new technology also ensures the parallelism of the tread lamellae 5. Since no toothed belt drive is provided, such an arrangement is distinguished by particularly low-noise operation. In addition, the treadmill device runs particularly smoothly and evenly.
- FIGS 3 and 4 show a second embodiment of the treadmill device according to the invention. Again, the same components are provided with the same reference numerals.
- the stabilizers 18 extend parallel to the deflection shaft 4 away from the deflection disks 3a, 3b.
- the engagement areas 19, in the exemplary embodiment shown the ends of the stabilizers 18, are in turn covered with elastic material.
- Two stabilizers 18 each extend away from the deflection disks at the same angular position.
- the radius on the deflection disks 3a, 3b, on which the stabilizers 18 are located, is selected so that the engagement areas 19 engage with the engaging elements 6a on the underside of the tread plates 5.
- the stabilizers 18 can be screwed to the deflection disks 3a, 3b or attached in some other way.
- FIG. 4 shows a partial sectional view of the second embodiment along the line BB in Figure 3.
- the operation of the second embodiment corresponds to the first embodiment. Due to the special arrangement of the stabilizers, further savings in weight and material are possible, which ensures an even smoother run.
- FIG. 5 shows a further embodiment which has stabilizers 28 which correspond to the stabilizers 18 in the second embodiment.
- the engagement areas 29 of the stabilizers 28 correspond to the engagement areas 19 of the stabilizers 18 of the second embodiment.
- a connection 30 is also provided, which can be designed as a rod or tube.
- the two opposite stabilizers 28 and the connection 30 can form a structural unit. Since two stabilizers arranged opposite each other are connected to each other in this way, it is possible to omit the central shaft between the deflection disks 3a, 3b.
- the functioning of this further embodiment corresponds to the two above embodiments.
- a treadmill device thus enables 100% reproducibility of parameters, such as the simulated running distance, the speed and the force setting, since no slippage can occur between the belt 2 and the deflection roller 3. Such slippage is prevented by the engagement of stabilizers with the tread lamellae 5.
- the stabilizers also serve to keep the individual tread slats 5 in parallel.
- toothed belts and ring gears on the deflection roller can be dispensed with, which ensures particularly quiet and quiet running.
