    The present invention relates to a bicycle pedal with a pedal body, the pedal body having a first platform and at least one second platform and a pedal axle receiving body disposed between the platforms, wherein in the pedal axle receiving body a pedal axle bolt of the bicycle pedal is shifted by one pitch. 5 dalachse rotatably arranged or can be arranged and the platforms are interconnected exclusively by intermediate webs kraftubertragend and the first platform is exclusively in force-transmitting connection via the intermediate webs and the second platform with the Pedalachsaufnahmekorper, wherein deformation measuring sensors, in particular strain gauges, for measuring a be-10 load-related deformation of the pedal body to the first platform and / or the intermediate webs and / or the second platform are arranged.
    Such bicycle pedals can be used in the medical-therapeutic field, in particular in rehabilitation but also in competitive sports or in sports in general 15 to measure the initiated for a person when pedaling in the bicycle pedal forces.
    From the article "Development of a triaxial force plate form for the measurement of force at a bicycle pedal " ISBS 2002, Cäceres -Extremadura - Spain, page 290 ff are 20 theoretical Beredinungen known for such a bicycle pedal However, there is at least theoretically calculated bicycle pedal necessary to use a calibration matrix to the measurement signals generated by the deformation measurement sensors in the actually introduced forces to be able to convert. It is an object of the invention to improve a generic bicycle pedal in such a way that the measurement signals measured by means of deformation measuring sensors are directly proportional to the introduced forces. The goal is therefore to make 21/04/2011 14:09

    00007/0037 2 signals can be directly deduced from the incoming forces without the need for a conversion by means of a calibration matrix or the like. In order to achieve this, the bicycle pedal has, in addition to the pedal body, a force introduction body which is in force-transmitting connection exclusively with at least two, preferably four, force introduction areas with the first platform, wherein at least one of the force introduction areas is on one side of the first platform is arranged and at least another of the force introduction regions is arranged with respect to the pedal axis on a side opposite to the first platform.
    First of all, it should be pointed out that in the bicycle pedals according to the invention as well as in generic bicycle pedals, the first platform is provided so that the forces are introduced into the pedal body when the pedal is pedaled. The first platform is but at no point in direct force-transmitting connection with the Pedalachsaufnahmekörper and thus with the rotatably mounted Pedalachsbolzen therein. Rather, it is provided in generic as in inventive pedal bodies, that the first platform transmits exclusively on the intermediate-20 webs forces on the second platform and on the second platform on the Pedalachsaufnahmekörper. This ensures that there is no force bypass within the pedal body. This ensures that all forces introduced into the first platform result in corresponding deformations of the intermediate webs and the two platforms, so that the measurement of these deformations by means of the deformation measuring sensors can be concluded from the forces introduced into the pedal body. However, in generic bicycle pedals, this is not enough to allow conclusions to be drawn directly from the measured signals of the deformation measuring sensors on the forces introduced. In order to avoid the conversion of the measured variables into the forces required in the state of the art, the bicycle pedal according to the invention thus provides, in addition to the pedal body, in addition to the two platforms and the intermediate webs connecting them, a force introduction body via which the bicycle pedal P.007 / 037 21/04/2011 14:09 No .: R832 21/04 2011 14:05 FAX +43 5522 73359 * ··· P ♦ »-1 1210008/0037 3 forces applied to the first platform. In this case, it is provided that the force introduction body is in force-transmitting connection exclusively with the first platform via the defined or spatially limited force introduction regions. Furthermore, according to the present invention, at least two of the force introduction regions relate to the pedal axis on opposite sides of the first Platform are arranged. By means of these force introduction regions, the forces acting on the force introduction body are thus always introduced into the first platform both behind and in front of the pedal axle. As a result, it is achieved according to the invention that the 10 measurement signals are directly proportional to the forces introduced and thus need not be calculated again in one calculation step. The calibration matrix required in the prior art is thus no longer needed. The measurement signals are conveniently in a linear relationship with the forces introduced. 15
    The pedal according to the invention is referred to as a bicycle pedal For the sake of completeness, however, it should be noted that this is not to be understood that such bicycle pedals can be mounted exclusively on provided for locomotion bicycles. Bicycle pedals according to the invention can also be used on stationary bicycles as well, for example. B. ergometers, exercise bikes u. Like. Be used. Important target areas are the medical and therapeutic treatment and analysis of patients, especially during rehabilitation. However, bicycle pedals according to the invention can just as well be used in the sports sector and in particular in competitive sports in order to check and optimize the movements and force distributions of the athlete or competitive athlete when riding a bicycle.
    By means of the invention, for the first time with such a bicycle pedal or measuring body, it has been possible to separate both forces in the Z and X axes independently of the respective pedal angle with high accuracy and to measure them visually without any mutual influence. 21/04/2011 14:10

    This solution makes it possible to measure the forces with accuracy in all 3 axes under 0.5% linearity error.
    Thus, the muscular load and the load on the foot, knee and hip joints can now be measured with high accuracy.
    Another aspect is the optimal training on the road bike with respect to the round kick, i. It can achieve an optimal use of force during the entire crank rotation and thereby the pedal performance can be converted into the pre-10 forward movement with great efficiency.
    Regarding rehabilitation after leg or foot surgery, a treatment plan for recovery can now be created and also measured and controlled to optimize the healing process. 15
    For the sake of completeness, it is also pointed out that a force-transmitting connection in the sense of the invention means a connection via which forces to be measured can also be transmitted. Thus, two webs may theoretically be considered interconnected via the interposed air. However, this is not a force-transmitting connection in the sense of the invention. This is only possible if these webs are connected to each other directly or with the interposition of further, force-transmitting webs. Theoretically, the first as well as the second platform can be designed as self-contained plates. It is more favorable, however, if at least one of the two, preferably both, platforms are constructed of webs connected to one another in a force-transferring manner. So z. B. be provided that the first and / or the second platform each have one, two, four or more Lingsstege, said 30 longitudinal webs by means of at least one or two transverse webs are in force-transmitting connection with each other.

    Particularly preferred embodiments of the invention provide that the at least two force introduction regions, which are arranged with respect to the pedal axle on opposite sides of the first platform, are equidistant from the pedal axle. The term spaced is understood to mean that a distance greater than zero voriiegt is particularly favorable when the at least two force introduction regions, which are arranged with respect to the pedal shaft 10 on opposite sides of the first platform to each other with mirror symmetry with respect to an imaginary plane of symmetry Pedal axis lies in the plane of symmetry. In terms of the highest possible accuracy of measurement, it is further favorable if two of the intermediate webs are mirror-symmetrical to each other with respect to an imaginary plane of symmetry 15 and arranged, the pedal axis is in the plane of symmetry The intermediate webs should therefore not only arranged symmetrically with respect to the symmetry axis but also formed be. They should therefore have the same material as well as the same cross-sections at the corresponding points. This also applies to the platforms or the webs, from which 20 the platforms are formed.
    In this context, it should also be noted that preferred embodiments of the invention provide that the pedal body, so the two platforms, the intermediate webs and the Pedalachsaufnahmekörper from a single monolithic body z.

In this case, a separate force introduction bolt can be guided through each receiving opening. However, the force introduction bolts can also be passed in pairs through each two opening openings in order to transmit the forces from the force introduction body to the first platform of the pedal body.
    In order to be able to fasten a shoe of the person actuating the bicycle pedal on the force introduction body, preferred embodiments of the invention provide that the force introduction body has a binding device for fastening a shoe to the force introduction body Such binding devices are known per se in the prior art The associated pedals with such Binding devices are often referred to as clipless pedals. Most common binding devices known in the art may be attached to the force introduction body. It is favorable in general when the binding device has a binding plate and at least one, preferably resilient, movable, preferably pivotable, binding jaws for fastening a binding counterpart of the shoe on the binding plate. With regard to the number and arrangement of the deformation measuring sensors, preferred embodiments of the invention provide that two, four or eight deformation measuring sensors are arranged at respectively different locations of the first platform and / or the second platform and / or the connecting webs and in a Wheatstone Half bridge or full bridge or double bridge with each other ver-25 are switched.

Favorable here is a mirror-symmetrical arrangement with respect to a lying on the pedal axis symmetry point.

In this case, the pedal crank 88 together with the bicycle pedal 61 can be rotated about the crank axis 89. The pedal body 62 of the bicycle pedal 61 can be rotated about the pedal axis 67 and thus also to the pedal axle bolt 66 relative to the pedal-5 crank 88. This is standard in known bicycle pedals, so this need not be explained further. It is merely pointed out that the bicycle pedal 61 includes the pedal body 62 and the pedal axle bolt 66 and further additional components according to the invention explained below. Left next to the bicycle pedal 61 shown schematically, the directions of the force components F_X to be determined are also shown in FIG. F_Y and F_ £ are drawn. In the following, the force component which runs in the direction of the pedal axis 67 is referred to as F_Y. F_Z is the force component in the vertical direction. F_X is the force component in the third direction, ie in the horizontal direction. T_X and T_Z are the torques that can act on the bicycle pedal 61. T_X is the torque about the axis F_X, T_Z is the torque about the vertical axis F_Z.
    Fig. 2 shows a first embodiment according to the invention of a pedal body 62 of a bicycle pedal 61 according to the invention, however, the force introduction body 20 tion body 72 of this bicycle pedal 61 is not yet attached to the pedal body 62. The pedal body 62 of this exemplary embodiment has a first platform 63 and a second platform 64. These two platforms 63, 64 are connected to one another in a force-transmitting manner exclusively via the four intermediate webs 68, 69, 70 and 71. In operation, the first platform 63 and the second platform 64 are substantially horizontally horizontal. The intermediate webs 68,69,70 and 71 are generally substantially vertical in the operating state.
    On the second platform 64 of the pedal axle receiving body 65 is attached. The pedestal receiving body 65 serves to receive and rotatably support the pedal shaft bolt 66. The pedal axle bolt 66 is not shown in FIGS. 2 to 20. The bearing of the pedal axle bolt 66 in the pedal axle housing body 65 can take place as known in the prior art.

In order to safely switch off force shunts, ie the possibility of a direct force transmission between first platform 63 and pedal axle receiving body 65, it is favorable if, as in the exemplary embodiment shown, an exemption 90 or a corresponding free space between first platform 63 and pedal axle receiving body 65 10 As shown in also other exemplary embodiments, both the first platform 63 and the second platform 64 are constructed not as continuous plates but from webs connected to one another in a force-transmitting manner. For this purpose, the first platform 63 has a total of four longitudinal webs 91, 92, 93 and 94, which are interconnected via the transverse webs 95 and 96 as well as via a central transverse web 106 in a transferring manner. In the illustrated embodiment, the longitudinal webs 91,92,93 and 94 together with the transverse webs 95 and 96 form a frame which forms the first platform together with the central web 106 and also limited to the outside. In the first exemplary embodiment according to FIGS. 2 to 10, the second platform 64 is at least similar to the first platform 63. Here, too, there are a total of four longitudinal webs 97, 98, 99 and 100, as well as two transverse webs 101 and 102 connecting them to one another. These longitudinal webs 97 to 100 and transverse webs 101 and 102 also form a frame which limits the second platform 64 to the outside. Instead of the central web 106, the pedal axle receiving body 65 is provided in the second platform 64. The central web 106 is separated from the Pedalachsaufnahmekörper 65 by means of the already mentioned exemption 90, so that it can also come here no force shunts, but all introduced to the first platform 63 forces exclusively on the intermediate webs 68,69,70 and 71 on the webs of the second 30 platform 64 are transferred.

    The transverse webs 95r 96,101 and 102 extend in this embodiment, all parallel to the pedal axis 67. The longitudinal webs 91 to 94 and 98 to 100 extend in this embodiment, all orthogonal to the pedal axis 67 and to a parallel through the pedal axis 67. In the embodiment shown is in common with the pedal body 62 and its previously described components, as is generally the case with an integrally formed body. All components are thus materially connected to each other in the form shown. This is particularly favorable in terms of optimum power transmission. In FIG. 2, the plane of symmetry 77 is also shown, with respect to which the pedal body 62, the force introduction regions 73, 74, 75 and 76 and also the force introduction body shown in FIG. 3 have the symmetries mentioned above.
    The pedal shaft 67 extends in this plane of symmetry 77. If the first platform 63 and the second platform 64 are aligned horizontally, then the plane of symmetry 15 77 extends vertically.
    In FIG. 3, according to the invention, the force introduction body 72 is connected to the first platform 63 of the pedal body 62 via the force introduction regions 73, 74, 75 and 76. The force introduction regions 73, 74, 75 and 76 represent the only force-transmitting connection between the force introduction body 72 and the first platform 63 or the entire pedal body 62. The force introduction body 72 has a binding device 80 in the exemplary embodiment shown. This includes a binding plate 81 and two binding jaws 82 and 83. In the illustrated embodiment, the front binding jaw 83 is rigidly fastened to the binding plate 81, while the rear binding jaw 82 is pivotable with respect to the binding plate 81 and the binding jaw 82 so as to permit the entry of one not shown here, to allow the bicycle shoe attached connection plate. Such binding devices 80 are known per se in the prior art and therefore need not be further explained.

In the exemplary embodiment shown, one force introduction pin 79 5 is guided through two mutually opposite receiving openings 78. However, this need not be so it is also possible for a separate force introduction bolt 79 to be provided for each force introduction region 73, 74, 75 and 76.
    By using a force introduction body 72 according to the invention, it is possible to directly measure measurement signals 1 to 58 with the arrangements of deformation measuring sensors 1 to 58, which are directly proportional to the force components F_X, F_Y and / or F_Z and / or directly proportional to the introduced torques T_X or T_Z are. A further advantage of the connection according to the invention of the force introduction element 15 with the first platform 63 via defined force introduction regions 73, 74, 75 and 76 located in front of and behind the pedal axis 67 is that the measurement signal introduces the correct value of the force introduction body 72 Force component or torque component reflects, regardless of where exactly the binding plate 81 and the force introduction body 72 is charged. So it makes no difference where on the binding plate 81 exactly the force component or the torque is introduced. As long as the amount is constant, the generated measurement signal is also constant. Points 107, 108 and 109 exemplarily illustrate different force introduction points on the binding plate 81 and the force introduction body 72, respectively. 25

    Torque components to be measured. As subsequently shown by way of example, for measuring a single force component two, four or even eight deformation measuring sensors 1 to 58 mounted at different locations of the bicycle pedal 61 can be used. There are also various ways of measuring one and the same component, as will be explained later on. Furthermore, it should be noted that despite the extensive presentation not all possibilities of the arrangement of deformation measuring sensors 1 to 58 and their interconnections are drawn. It should further be noted that some of the strain gauges 1 to 10 58 shown here, which are used in several circuits or configurations, are designated by a plurality of reference symbols. However, in the case of several reference symbols for a deformation measuring sensor, it is always only a single deformation measuring sensor or strain gauges at the respective location. Finally, it should be pointed out that the deformation measuring sensors 1 to 58 shown in solid lines in the respective view 15 can also be seen in this view, while the deformation measuring sensors 1 to 58 shown in dashed lines are each arranged behind a web and thus actually hidden in the respective view , In order to be able to represent the arrangement and positioning of the various deformation measurement sensors 1 to 58, a total of seven representations have been selected for the first exemplary embodiment in FIGS. 4 to 10. 4 shows a longitudinal section through the bicycle pedal 61 along a first sectional plane. This first cutting plane is normal to the plane of symmetry 77 and the pedal axis 67 forms a surface normal to this cutting plane, in Fig. 5 is also a longitudinal section shown. However, although the cutting plane is normal to the plane of symmetry 77, it also extends along the pedal axis 67. FIG. 5 thus shows a plan view of the second platform 64.

    It can be seen particularly well in FIG. 8 that at least one of the force introduction regions 73-76 is arranged on one side of the first platform 63 and at least one other of the force introduction regions 73-76 is arranged on a side 5 of the first platform 63 opposite to the pedal axis 67 is arranged. Before discussing the position and interconnection of the deformation measuring sensors 1 to 58, reference is again made to the symmetries realized in this bicycle pedal 61. These can be seen particularly well in FIGS. 4 and 8. In Fig. 8 is initially good to see that the two visible in this perspective power input processing areas 74 and 75 are equidistant from the pedal axis. In the exemplary embodiment shown, however, they are not only equidistantly spaced, but lie mirror-symmetrically with respect to the imaginary plane of symmetry 77, in which also the pedal axis 67 lies. It can also be seen both in FIG. 4 and in FIG. 8 that both the first platform 63 and the second platform 64 are mirror-symmetrical with respect to the symmetry axis 77 already mentioned. Also, the intermediate webs 68 to 71 are arranged with respect to this plane of symmetry 77 both mirror-symmetrical and formed. In the case of these mirror symmetries, the focus is primarily on the fact that the same deformations occur in the part of the pedal body 62 in front of the plane of symmetry 77 as there is in the part of the pedal body 62 which lies behind the plane of symmetry 77. The term "front" designates in the embodiment shown the part of the pedal body 62, on the side of which with respect to the plane of symmetry 77 of the binding jaws 83 is arranged. The area behind the symmetry axis 77 can be recognized by the fact that the binding jaw 82 is arranged there. 25
    As already stated, in order to determine the individual force components FJ (, F_Y and / or F_Z or the torques T_X and / or T_Z, various deformation measuring sensors 1 to 58 arranged at different positions can be used For example, 30 deformation-measuring sensors 1 to 38 are shown in the first embodiment Figures 21, 22 and 23 show ways in which these individual deformation-measuring sensors can be connected to one another in order to determine the respective measuring signal, which is then proportional to the respective measurement signal : 16

The assignment results for the first embodiment according to FIGS. 2 to 10 from the table in FIG. 24. Here, different alternatives for determining the individual force components and torque components are given by way of example. So z. For example, if a measuring signal proportional to the force component F_Z is to be measured, the deformation measuring sensors 1, 2, 3 and 4 can be used, which can be interconnected in the Wheatstone full bridge shown in FIG Circuit sets the deformation measuring sensor 1 to the position A, the deformation measuring sensor 2 to the position B, the deformation measuring sensor 3 to the position C and the deformation measuring sensor 4 to the position 15 D Wheatstone's full bridge, as is apparent from Fig. 24 Alternatively, a but also be generated by the use of only two deformation measuring sensors 9 and 10. Thus, for example, the deformation measuring sensor 9 can be moved to the position E of the Wheatstone half bridge 84 of Fig. 22 and the deformation measuring sensor 10 to the Put Po-20 position F of Wheatstone's half-bridge 84. However, it is also possible to create eight deformation terms Sense sensors 11 to 18 for measuring a signal proportional to the force component F_Z signal. Thus, the deformation measuring sensors 11 to 14 can be set to the positions A to D of the first full bridge and the deformation measuring sensors 15 to 18 to the positions A to D of the second full bridge of the Wheatstone double bridge shown in FIG. Generally speaking, the higher the signal quality, the more deformation measuring sensors 1 to 58 are used to determine the measurement signal. In the sense of a ruffled representation, it is decided not to explicitly address each individual circuit.

Wheatstone bridges 84,85 and 86 of the type mentioned are known per se and need not be further explained. 10 Generally speaking, with respect to the arrangement of the deformation measuring sensors, it is favorable if at least two of the deformation measuring sensors interconnected in a respective Wheatstone half, full or double bridge 84 to 86 are arranged on mutually opposite sets of the plane of symmetry 77 or pedal axis 67. Preferably, it is even provided that at least two 15 of these deformation measuring sensors, which are interconnected in a half, full or double bridge, are each arranged diagonally opposite or point symmetric with respect to a symmetry point lying in the plane of symmetry 77. The mentioned deformation sensors 1 to 58, which are interconnected correspondingly one behind the other, are expediently equally spaced in pairs from 20 of the plane of symmetry 77.
    As the various interconnections shown by way of example show, the deformation measuring sensors 1 to 18 provided for the force component F_Z for measuring signal determination are preferably arranged on the second platform 64 or on their longitudinal webs 97 to 100. The measuring signals used for determining the force component F_X are advantageously generated by deformation measuring sensors 23 to 32, which are fastened to the intermediate webs 68 to 71 and measure their deformation. In order to determine the force component F_Y in the direction of the pedal axis 67, the deformation measuring sensors 33 to 36 can be arranged in the transitional area between the intermediate webs 68 and 71 and the first and second platforms 63 and 64 or their transverse webs 95, 96, 101 and 102 this is particularly apparent from Figs. 8 to 10.

    Torque component T_Z used deformation measuring sensors 19 to 22 are particularly well seen in Fig. 5. Conveniently, as shown here, they are arranged in the points of intersection between the longitudinal webs 97 to 100 of the second platform 64 and the pedal axle receiving body 65. 5
    The second embodiment of a bicycle pedal 61 according to the invention is shown in FIGS. 11 to 20. The symmetries already explained with respect to the first embodiment are also realized here. The plane of symmetry 77 is shown by way of example in FIG. 12. FIG. 11 shows a perspective view from above of the bicycle pedal 61. FIGS. 12 and 13 show side views from the opposite sides. Fig. 14 is a plan view, Fig. 15 is a bottom view. Fig. 16 shows the view from the front, Fig. 17 shows the view from behind. Fig. 18 is a further view from below. Fig. 19 is a further front view and Fig. 20 is a further rear view of this bicycle pedal 61 of the second Ausfüh-15 approximately example. For the arrangement and interconnection of the deformation measuring sensors 39 to 58, which are also expediently designed here as strain gauges, what has been said for the first exemplary embodiment applies, but the assignment table of the deformation measuring sensors 39 to 58 used here is to the positions A to F in the various Wheatstone bridges 84 to 86 in Fig. 25 again.
    The structure of the first platform 63 and the attachment of the force introduction body 72 via the force introduction regions 73 to 76 in the second embodiment corresponds to the construction of the first embodiment. The essential difference from the first exemplary embodiment lies in the construction of the second platform 64. Instead of the total of four longitudinal webs 97 to 100 of the first exemplary embodiment, the second platform 64 of the second exemplary embodiment has only two centrally arranged longitudinal webs 98 and 99. Accordingly, the two platforms 63 and 64 of this second embodiment are connected to each other only two intermediate webs 68 30 and 70 force-transmitting. For the release 90 between the first platform 63 and the Pedalachsaufnahmekörper 65 is the introductory to the first embodiment said above. 21/04/2011 14:18

    FIG. 26 also shows a graphic representation of the proportionality between the measurement signal tapped between the signal taps 104 and the force component actually to be determined. By way of example, the vertical force '5 component F_Z and the associated measurement signal Fzm are shown here. Corresponding representations, however, also result for the other force components as well as for the torque components. It is particularly important to point out that in the case of a pure initiation in the direction of one of the force components, the other components show no measuring signals or the measuring signal zero. When force is applied exclusively in the direction F_Z, no measurement signals or the measurement signal zero for F_X, F_Y and also no measurement signal or the measurement signal zero for the torque components T_X and T_Z thus occur. 21/04/2011 14:19
