[0001] TITLE

[0002] ADJUSTMENT SYSTEM AND / OR MEASURING SYSTEM FOR A SKI BINDING

[0003] TECHNICAL FIELD

[0004] The present invention relates to an adjustment system for a sports device according to claim 1 and a measuring system for a sports device according to claim 4.

[0005] STATE OF THE ART

[0006] For winter sports equipment such as skis or snowboards, the binding adjustment is crucial in terms of size and release. Typically, the user's stature, weight, and skiing ability are taken into account. Once the adjustment is complete, there is usually no further adjustment that would include other parameters, such as snow quality, actual movement patterns, the user's physiology, etc.

[0007] PRESENTATION OF THE INVENTION

[0008] The present invention is based on an object of providing an adjustment system for a sports device which enables a user to adjust a contact pressure unit of a binding in which the shoe is clamped, based on the prevailing conditions and individually.

[0009] These and other objects are achieved by the adjustment system according to claim 1. Accordingly, an adjustment system for a piece of sports equipment comprises a shoe, a binding with at least one shoe holder which has an adjustable contact pressure unit, wherein the shoe is mounted as intended in the shoe holder and is subjected to a force by the contact pressure unit which corresponds to the setting of the contact pressure unit, at least one sensor unit with a first sensor element, a second sensor element and with a data interface on the sensor unit side, wherein the first sensor element is arranged at a fixed position with respect to the binding and wherein the second sensor element is fixedly arranged on the shoe, a computer with a computer-side data interface and a processor, and a display unit which is operatively connected to the computer.

[0010] The sensor unit is designed to detect a relative displacement between the boot and the boot holder and to provide signals corresponding to the relative displacement to the sensor unit-side data interface. The sensor unit-side data interface and the computer-side data interface are configured for data exchange such that the signals can be transmitted from the sensor unit-side data interface to the computer-side data interface. The processor is configured to process the signals such that the relative displacement between the boot and binding can be calculated from the signals, so that information about the setting of the contact pressure unit of the binding can be derived from the calculated relative displacement and displayed on the display unit.

[0011] Particularly preferably, the user is shown whether the setting of the contact pressure unit is correct or whether adjustment is necessary. If adjustment is necessary, it is preferably indicated that the contact pressure unit of the binding is set too hard or the contact pressure unit of the binding is set too soft.

[0012] Preferably, a single sensor unit is provided. In other embodiments, multiple sensor units can be provided. In particular, one sensor unit can be assigned to a first binding part mentioned below, and one sensor unit can be assigned to a second binding part mentioned below. In another embodiment, it would also be conceivable to place the sensor units as a matrix or in another arrangement.

[0013] For ski bindings, it is particularly preferred to indicate whether the ski binding's Z-value needs to be adjusted upwards or downwards. For example, the user is shown a difference value by which the Z-value needs to be adjusted, or the user is shown a Z-value to be adjusted. Depending on the type of binding, the relative displacement can be a translational displacement and / or a rotational displacement.

[0014] The term "calculable" means that the relative displacement is calculated, determined or derived from the signals of the sensor unit.

[0015] Preferably, the shoe is guided in its mobility in the binding holder.

[0016] If the sports equipment is a ski and the binding is a ski binding, the contact pressure unit is provided by a toe apparatus and a heel apparatus. The toe apparatus clamps the toe of the boot, and the heel apparatus clamps the heel of the boot. Preferably, both the toe apparatus and the heel apparatus are configured to adjust the binding. Particularly preferably, the information about the adjustment comprises adjustment information for the toe apparatus and adjustment information for the heel apparatus. Thus, the toe apparatus and the heel apparatus can be adjusted independently of one another based on the measured relative displacement.

[0017] Preferably, during signal processing, the relative displacement corresponding to the signal is compared with a limit value range, wherein the limit value range represents an optimal setting of the contact pressure unit. If the measured relative displacement is outside the limit value range, the information to be displayed can be supplemented with readjustment information, such that a readjustment of the contact pressure unit of the binding can be displayed. If the measured relative displacement is within the limit value range, the information to be displayed can be supplemented with confirmation information, such that a confirmation message can be displayed.

[0018] In one variant, the limit range can include limit values ​​as such. For example, a displacement in millimeters.

[0019] In another variant, the threshold range can also include statistical limits, for example, a Gaussian normal distribution. With a Gaussian normal distribution, a quantile can be selected for the threshold range. The larger the selected quantile, the lower the probability of false triggering, but the higher the probability of non-triggering. The smaller the selected quantile, the higher the probability of false triggering, but the lower the probability of non-triggering.

[0020] The comparison between the relative displacement and the limit range can be recorded over time to reflect changes in the athlete’s driving behavior,

[0021] Furthermore, the limit range can be changed dynamically, allowing third-party influences to be taken into account, such as the time of day, the hardness of the slope, etc. Correction factors can be used, for example, to account for these dynamic changes.

[0022] Preferably, the user can set their preference for the threshold range. For example, an amateur athlete might choose a larger range than a professional athlete.

[0023] Preferably, the direction from the heel of the shoe to the toe of the shoe is defined as the Y-axis. The direction transverse to the Y-axis and parallel to a support surface of the sports equipment on which the binding can be arranged is defined as the X-axis. The direction transverse to the X-axis and transverse to the Y-axis is defined as the Z-axis. Particularly preferably, the sensor unit is designed such that a relative displacement of the shoe can be detected as a translational movement in at least one, in particular in all three, axes; and / or that the sensor unit is designed such that a relative displacement of the shoe can be detected as a rotational displacement about at least one, in particular about all three, axes.

[0024] The present invention is further based on the object of specifying a measuring system for a piece of sports equipment that measures a relative displacement of a shoe clamped in a binding. This and other objects are achieved by the subject matter according to claim 4. Accordingly, a measuring system for a piece of sports equipment comprises a shoe, a binding with at least one shoe holder having an adjustable contact pressure unit, wherein the shoe is mounted in the shoe holder as intended, and a sensor unit with a first sensor element, a second sensor element, and a data interface on the sensor unit side, wherein the first sensor element is arranged at a fixed position with respect to the binding and wherein the second sensor element is arranged fixedly on the shoe.

[0025] The direction perpendicular to the Y-axis and parallel to a support surface of the sports equipment on which the binding can be placed is defined as the X-axis. The direction perpendicular to the X-axis and perpendicular to the Y-axis is defined as the Z-axis.

[0026] The sensor unit is designed such that a relative displacement of the shoe can be detected as a translational movement in at least one, in particular in all three, directions; and / or that the sensor unit is designed such that a relative displacement of the shoe can be detected as a rotational displacement in at least one, in particular in all three, directions.

[0027] This measuring system allows you to accurately measure the position of the boot relative to the binding.

[0028] The measuring system preferably comprises a computer with a computer-side data interface and a processor, and a display unit operatively connected to the computer. The sensor unit is designed to detect a relative displacement between the shoe and the shoe holder and to provide signals corresponding to the relative displacement to the sensor unit-side data interface. The sensor unit-side data interface and the computer-side data interface are configured for data exchange such that the signals from the sensor unit-side data interface can be transmitted to the computer-side data interface. Furthermore, the processor is configured to process the signals such that the relative displacement between the shoe and the binding can be calculated from the signals.

[0029] Preferably, the processor is designed such that the detected or calculated relative displacement is comparable to a predefined relative displacement, wherein if the determined relative displacement exceeds the predefined relative displacement, an error condition can be detected.

[0030] In a particularly preferred embodiment, the predefined displacement can also be modified with parameters or influences to refine the actual behavior. Examples include temperature compensation or adapted limit values. The relative displacement measured by the measuring system or the data resulting from this comparison can be used in a variety of ways, for example, for the following purposes:

[0031] - Detection of faults and / or

[0032] - Detection of wear and / or defects on the binding and / or

[0033] - Detection of fatigue or the physiological state of the user and / or

[0043] Preferably, the change in the angle of the direction vector in the plane spanned by the X and Z directions is considered for the relative displacement. This is especially important for binding adjustment, because the displacement in the Y direction is usually very small and therefore hardly significant.

[0044] Alternatively, the change in the angle of the direction vector in three-dimensional space can be considered for the relative displacement.

[0045] The sensor unit can be based on different physical effects, such as inductive, capacitive, optical, geometric, electrical or geometric measurement.

[0070] Fig. 2 is a schematic view of a measuring system for a sports device, and

[0071] Fig. 3 is a schematic view of an evaluation of a measurement in the setting system according to Figure 1 or in the measuring system according to Figure 2.

[0072] DESCRIPTION OF PREFERRED EMBODIMENTS

[0073] Figure 1 shows an adjustment system for a piece of sports equipment, in this case a ski. Figure 2 shows a measurement system for a piece of sports equipment, in this case a ski. Many elements of the systems are identical or similar in design and bear the same reference numerals. The adjustment system 1 for a piece of sports equipment, in this case a ski, comprises a boot 2, a binding 4, a sensor unit 7, a computer 11, and a display unit 14.

[0074] The shoe 2 is held in the binding 4 by the toe 17 and the heel 18. Furthermore, the shoe 2 has a sole 3.

[0075] The binding 4 has at least one shoe holder 5. The shoe holder 5 has an adjustable contact pressure unit 6. The shoe 2 is mounted in the shoe holder 5 as intended. The contact pressure unit 6 applies a force to the shoe 2 that corresponds to the setting of the contact pressure unit 6. This force defines the hold of the shoe 2 in the shoe holder 5. In the embodiment shown, the binding has a front binding part 15, on which the shoe toe 17 is mounted, and a rear binding part 16, on which the shoe heel 18 is mounted. The contact pressure unit 6 is arranged in the front binding part 15 and / or the rear binding part 16. This means that the front binding part 15 and / or the rear binding part 16 are adjustable.

[0076] The sensor unit 7 comprises a first sensor element 8, a second sensor element 9, and a data interface 10 on the sensor unit side. The first sensor element 8 is arranged at a fixed position with respect to the binding 4. The second sensor element 9 is fixedly arranged on the shoe 2. The two sensor elements 8, 9 are capable of detecting the relative displacement between the shoe 2 and the shoe receptacle 5 within the scope of the mobility between the shoe 2 and the shoe receptacle 5. The sensor unit 7 is accordingly designed to detect a relative displacement between the shoe 2 and the shoe receptacle 5 and to provide signals S corresponding to the relative displacement to the data interface 10 on the sensor unit side.

[0077] The computer 11 comprises a computer-side data interface 12 and a processor 13. The display unit 14 is operatively connected to the computer n.

[0078] The sensor unit-side data interface 10 and the computer-side data interface 12 are configured for data exchange such that the signals S can be transmitted from the sensor unit-side data interface 10 to the computer-side data interface 12. The data connection between the sensor unit-side data interface 10 and the computer-side data interface 12 can be wired or wireless. The processor 13 is configured to process the signals S from the sensor unit 7 such that the relative displacement between the boot 2 and the binding 4 can be calculated, determined, or derived from the signals S.

[0079] Information I about the setting of the contact pressure unit 6 of the binding 4 can be derived from the calculated relative displacement and displayed on the display unit 14. For example, the display unit 14 can indicate whether the setting of the contact pressure unit is correct or whether an adjustment is necessary.

[0080] For example, when processing signal S, the relative displacement corresponding to signal S is compared with a limit value range. The limit value range represents an optimal setting of the contact pressure unit 6. If the measured relative displacement is outside the limit value range, the information to be displayed can be supplemented with readjustment information such that a readjustment of the binding 4 can be displayed. The limit value range can be fixed or can be dynamically parameter-dependent. The user receives a notification on the display unit 14 that the contact pressure unit 6 of the binding 4 needs to be adjusted. If the measured relative displacement is within the limit value range, the information to be displayed can be supplemented with confirmation information such that a confirmation message can be displayed.The user receives an indication on the display unit 14 that the contact pressure unit 6 of the binding 4 is correctly adjusted.

[0081] The direction from the heel 18 to the toe 17 of the shoe is defined as the Y-axis. The direction perpendicular to the Y-axis and parallel to a support surface 19 of the sports equipment, on which the binding 4 can be arranged, is defined as the X-axis. The direction perpendicular to the X-axis and perpendicular to the Y-axis is defined as the Z-axis.

[0082] The sensor unit 8 is designed such that a relative displacement of the shoe 2 can be detected as a translational movement in at least one of the aforementioned directions, i.e., at least in the direction of the X-axis, the Y-axis, and / or the Z-axis. Preferably, the relative displacement can be detected in the direction of the X-axis and the Z-axis. Particularly preferably, the relative displacement can be detected in all three directions, i.e., in the direction of the X-axis, the Z-axis, and the Y-axis.

[0083] Additionally or alternatively, the sensor unit 8 is designed such that a relative displacement of the shoe 2 can be detected as a rotational displacement about at least one, in particular about all three, axes. This means that the rotation about the X-axis and / or about the Z-axis and / or about the Y-axis can be detected.

[0084] The measuring system for a piece of sports equipment shown in Figure 2. Like the adjustment system, the measuring system comprises the shoe 2, the binding 4 with the shoe holder 5, which has the adjustable contact pressure unit 6, wherein the shoe 2 is mounted in the shoe holder 5 as intended, and the sensor unit 7 with the first sensor element 8, the second sensor element 9, and the sensor unit-side data interface 10, wherein the first sensor element 8 is arranged at a fixed position relative to the binding 4 and wherein the second sensor element 9 is arranged fixedly on the shoe 2.

[0085] The sensor unit 8 on the measuring system is essentially the same as the sensor unit on the setting system and reference is made to the above description.

[0086] The measuring system can also comprise a computer 11 and a display unit 14, which is configured essentially the same as the computer and display unit according to the adjustment system. Reference is also made here to the above description. The processor 13 is configured to process the signals S in such a way that the relative displacement between the boot 2 and the binding 4 can be calculated from the signals S.

[0087] Preferably, the processor 13 is further configured such that the calculated relative displacement is comparable to a predefined relative displacement, wherein if the determined relative displacement exceeds the predefined relative displacement, an error condition is detectable.

[0088] The computer can be arranged differently in the adjustment system and, if applicable, in the measuring system. In one variant, the computer 11 can be arranged remotely from the binding 4, as shown in Figure 1. The computer 11 is then preferably a mobile computer, such as a tablet or a smartphone. Here, the display unit 14 and the computer 11 are combined in one device. However, the computer 11 can also be part of a network structure, in particular a cloud structure or internet-based structure, and the display unit 14 can be designed separately from the computer.

[0089] In another variant, the computer 11 can be provided by a microcontroller which is arranged in combination with the sensor unit 7, wherein the display unit 14 is formed separately from the computer 11.

[0090] Figure 3 shows the cross-section in the XZ plane of the sensor arrangement.

[0091] Using Figure 3 and also with reference to Figures 1 and 2, a preferred method of calculating the relative displacement will now be explained in more detail: In a first variant, a directional vector V is drawn from the stationary first sensor element 8 to the second sensor element 9 through a measured position P. The measured positions P are symbolized here by the line M. These are the measured values ​​that can be recorded when the shoe moves from a central position to the left or to the right. The directional vector V is then extended from the first sensor element 8 to the second sensor element 9. The intersection point between the directional vector V and the second sensor element 9 then yields the actual relative displacement.

[0092] The arc with the reference symbol M in Figure 3 shows the movement detected by the sensor array. The arc is formed by various measurement points from time-staggered measurements with different deflections. All measurement points on the left side of the Z-axis represent a deflection to the left in the X-direction. All measurement points on the right side of the Z-axis represent a deflection to the right in the X-direction.

[0093] The line Q shows the real movement of the second sensor element 9.

[0094] In Figure 3, the relative displacement in the plane spanned by the X and Z directions is determined. Accordingly, the change in the angle of the direction vector in the plane spanned by the X and Z directions is taken into account. Alternatively, the change in the angle of the direction vector in three-dimensional space can be considered for the relative displacement.

[0095] Preferably, the first sensor element 8 is a Hall sensor and the second sensor element 9 is a magnet.

[0096] The three-dimensional angular change of angle a can be calculated using the following formula: where a represents the angle change, x represents the magnetic flux density of the magnet in the X-direction measured by the Hall sensor, may y represents the magnetic flux density of the magnet in the Y direction measured by the Hall sensor, and may z represents the magnetic flux density of the magnet in the Z direction measured by the Hall sensor.

[0097] The first sensor element 8 can be formed separately from the binding 5 and can be connected to the binding 5 or the sports equipment. Alternatively, the first sensor element 8 can be integrally formed on or molded into the binding 5 or the sports equipment.

[0098] The second sensor element 9 is formed separately from the shoe 2 and can be connected to the shoe 2. Alternatively, the second sensor element 9 can be integrally formed on or molded into the shoe 2.

[0099] In the figures, the two sensor elements 8, 9 are shown spaced apart from each other. However, it is also conceivable for the two sensor elements 8, 9 to be arranged one above the other.

[0100] The displacement of the two sensor elements 8, 9 can be measured absolutely, starting from a zero position, or relatively, by measuring two measurements offset in time.
