Applicant claims priority under 35 U.S.C. § 119 of Austrian Application No. A 50448/2018 filed on Jun. 5, 2018, the disclosure of which is incorporated by reference.
The invention relates to a sports shoe, in particular a ski boot for exercising ski sports.
A generic sports shoe is known from AT517933B1, which traces back to the applicant. Several pressure-sensitive sensors are arranged on and/or in this sports shoe; they are connected via electric cable connections to a shoe-side electronic preparation device for the electrical sensor signals. It is challenging to implement such a sensor system in a manner that facilitates both practical use and serial production.
The object of the present invention was to overcome the disadvantages of prior art and to provide a sports shoe that would offer comprehensive data technology evaluation opportunities and could nonetheless be manufactured in a manner as cost-optimized and reliable as possible.
This object is solved with a sports shoe according to the invention.
According to the invention, a sports shoe, in particular a ski boot for exercising ski sports, is envisioned. This sports shoe has a lower portion of the boot intended to receive the foot of the user and an upper portion of the boot intended to receive the lower leg of this user, the upper portion of the boot being connected to the lower portion of the boot. A sensor assembly with several distributed pressure-sensitive sensors is thereby connected or can be connected via electric cable connections to an electronic signal processing device. At least two sensors of the sensor assembly are intended to be located on a sole assembly of the sports shoe, wherein at least one first sensor is positioned at the front portion of the sole assembly and at least one second sensor is positioned at the heel portion of the sole assembly. In the process, the at least one first sensor at the front portion of the sole assembly is connected with the at least one second sensor in the heel portion of the sole assembly via a multipolar flexible flat cable. The multipolar flexible flat cable is formed such that the length can be adjusted if necessary, such that a distance between the at least one first sensor and the at least one second sensor can be adjusted to different sole lengths during the manufacturing process of the sports shoe.
According to an alternative embodiment, it is also possible that at least a first or second sensor of the sensor assembly will be placed on a sole assembly of the sports shoe and at least a third or fourth sensor of the sensor assembly will be placed in the upper boot portion of the sports shoe. The at least one third or fourth sensor in the upper boot portion would thereby be connected to the at least one first or second sensor on the sole assembly of the sports shoe via a multipolar flexible flat cable, wherein the multipolar flexible flat cable may be adapted with an adjustable length if necessary. A distance between the at least one third or fourth sensor in the upper boot portion and the at least one first or second sensor in the sole assembly of the sports shoe can be changed as necessary, in particular in the upper boot portion with model-specific various height dimensions when manufacturing the sports shoe.
Sports shoes designed according to the invention have the advantage that they offer an optimized cost to use ratio. In particular with the pressure-sensitive sensors at the indicated positions, comprehensive data technology evaluation of the use and/or implementation circumstances of the sports shoe can be achieved. For example, this facilitates drawing relatively solid conclusions about the balance behavior of the sports shoe's user, which can be of particular importance in connection with alpine ski boots and the practice of skiing. Yet the sports shoes designed according to the invention with the indicated sensor detection devices can be manufactured and/or constructed as cost-effectively as possible. Because there is a multipolar flexible flat cable at least between individual sensors, rational production of the sensor system can be achieved in comparison with individual cable connections and/or cable cores. In particular, this also facilitates cost-effective serial production of generic sports shoes. The length settings and/or length adjustments of the multipolar flexible flat cable especially allow namely a certain type and/or version of the indicated sensor assembly to be used for many differently designed sports shoes or for many different shoe sizes. This also facilitates optimal positioning of the pressure-sensitive sensors, which allows high efficiency and/or greater use of the sensor system to be achieved. In addition, the indicated form is relatively robust and uncritical with regard to undesired disconnections. An added factor is that a corresponding integrated sensor system cannot be felt by the user's foot, meaning that impaired wearing comfort of the sports shoe can be excluded.
The further measures in accordance with an embodiment are also advantageous, as this allows the most cost-effective possible and also relatively extensive adaptability of the pressure recording positions of the respective sensors of the sensor assembly for different sole lengths and/or shoe sizes and/or cuff heights to be achieved. This usability of the most optimal pressure recording positions ensures improved condition monitoring and/or evaluation of the respective force and/or pressure conditions on and/or in the sports shoe.
Through the measures according to another embodiment, extensive alteration and/or adjustment of the distance between two sensors can be performed in an advantageous manner while still ensuring a reliable electrical connection across the distance between the sensors. The corresponding ability to adjust length is also robust and ensures long-term reliability.
The further development according to another embodiment offers quick adjustability and implementation of the sensor assembly in sports shoes with different dimensions. In addition, the correspondingly adjusted overlapping width can be designed to be especially reliable and/or with relatively low likelihood of error.
A particularly robust and especially easily constructed permanent overlapping of the flexible flat cable portions can be achieved through the measures according to a further embodiment. This especially allows the connection and/or bonding process to be implemented more simply and/or significantly more reliably.
Through the measures according to another embodiment, the electric connections in the portion between two sensors can be quickly and reliably adjusted to the respective intended and/or ideal distance between the sensors. In particular, this makes individual reduction and/or extension and electric coupling of cable ends unnecessary. The corresponding electrical connection can thus be created especially quickly and reliably for specific models and/or fits.
An additional embodiment may also be expedient. By altering the Z-shaped fold in the flexible flat cable, an adjustment in length and also direction and/or a change in course between the flexible flat cable portions can be achieved. In particular, this means that flexible flat cable portions with angles and connections with adjusted lengths can be adapted from straight flexible flat cable portions.
The measures in accordance with another embodiment are also advantageous, as they allow the electronic sensor system to be implemented in the sports shoe as cost-effectively and/or suitably in serial production as possible. In addition, this allows the manipulation effort for integration in and/or on a sports shoe to be kept as low as possible. In addition, this also allows an especially thinly structured sensor assembly to be achieved, in particular with a maximum thickness of less than 1 mm, preferably of less than 0.5 mm.
Through the measures according to other embodiments, the sensor-generated recording and evaluation of the force and/or pressure conditions between the foot of a user and the sports shoe and/or a sports device attached to it can be improved still more. In the process, the coupling of these sensors with flexible flat cables offers the production advantages and use-related effects specified above.
The measures in accordance with a further embodiment are also advantageous, as they allow the connector interface for electrical connection of the sensor system to be optimally positioned on an electronic signal processing device on the sports shoe.
Another embodiment is also advantageous in that it allows excessive strain of the flexible flat cable caused by stretching or compression while the sports shoe is used to be avoided, while the pressure-sensitive sensors remain in the optimal pressure recording positions.
Practical embodiments for the implementation of an appropriately functioning adjustment portion are indicated below.
The functional reliability of the adjustment portion for the flexible flat cable can be further increased through the measures in accordance with another embodiment. They especially facilitate the avoidance of increased clamp loads against the adjustment portion of the flexible flat cable.
Through the measures according to a further embodiment, an adjustment portion can be created with relatively extensive compensative capability without the risk of an undesired bend or other damage to the flexible flat cable.
In addition, through the measures according to another embodiment, undesired bends in the flexible flat cable within the adjustment portion can be minimized, and in addition, a compact adjustment portion can be created.
In addition, through measures according to a further embodiment, undesired tensions and/or increased tensile forces on the flexible flat cable can be minimized. This also allows high robustness and long-term reliability of the sports shoe and/or of its sensor system to be achieved.
Through the assembly of the individual sensors, which is linked in a series from a mechanical viewpoint, the production of the sensor assembly and also its implementation in various sports shoes can be simplified and/or made more efficient.
Through the measures according to another embodiment, an essentially straight sensor assembly can be created. In the process, the course of partial portions of the flexible flat cable via the toe portion and the heel portion of the sports shoe facilitates the process of implementation and the resulting build quality of the sports shoe.
Ultimately, the measures according to a further embodiment are also advantageous as they allow the flexible flat cable and/or at least partial portions of the flexible flat cable to be elastically extended and reset, thus achieving an especially robust and reliable implementation in sports shoes.
For the purpose of better understanding of the invention, it will be elucidated in more detail by means of the figures below.
These show in a respectively very simplified schematic representation:
First of all, it is to be noted that in the different embodiments described, given parts are provided with given reference numbers and/or given component designations, wherein the disclosures contained in the entire description may be analogously transferred to given parts with the same reference numbers and/or same component designations. Moreover, the specifications of location, such as at the top, at the bottom, at the side, chosen in the description refer to the directly described and depicted figure and in case of a change of position, these specifications of location are to be analogously transferred to the new position.
Instead of the ski boot depicted here as an example, the corresponding sports shoe 1 could also be designed as a cross-country ski boot, a snowboard boot, or other similar footwear. In particular, every shoe that comprises an exterior, comparatively stiff shell 2 and/or at least one relatively stiff cuff and shaft portion and a comparatively soft and flexible liner 3 set inside it and is intended for exercising ski sports should be seen as a generic sports shoe 1.
The depicted ski boot essentially consists of an exterior, relatively stable shell 2 and a comparatively flexible liner 3. It is preferred for the liner 3 to consist of foamed polymers and textile materials to offer the user the greatest possible wearing comfort when the user's foot is received by sports shoe 1, in particular liner 3. The liner 3 can preferably be carried out such that it can be removed from shell 2 or such that it is exchangeable, as is shown in
The exterior shell 2, formed of cast plastic as an example, can also have multiple openings and thus form a barred and/or cage-like structure for the liner 3. The exterior shell 2 around the liner 3 serves to transfer forces between the user's foot and the respective sporting device to which the ski boots is attached and/or arranged as efficiently and/or quickly as possible.
In both embodiment variants, whether as an alpine ski boot or as a touring ski boot, the liner 3 is received by the shell 2 and a foot received by the liner 3 can be held in the liner 3 through decreasing the volume of shell 2. Deceasing the volume of the shell 2 occurs through at least one tension device 4, typically buckles, wherein a different number of tension devices 4 can be arranged on the shell 2 on one ski boot according to the respective model.
It is preferred for the shell 2 to comprise a front foot shell 7 to receive the user's foot and a cuff 6 connected to the front foot shell 7, which at least partially surrounds and/or receives the lower leg of the user. The cuff 6—also known as the shoe shaft—should preferably be constructed as an independent element and should be connected to the front foot shell 7 with two pivot bearing devices 5. The pivot bearing devices 5 positioned on the opposing side surfaces of the sports shoe 1 therefore form a hinge joint between the cuff 6 and the front foot shell 7, which facilitates bending between the front foot shell 7 and the cuff 6. This jointed connection can of course also comprise connections that facilitate combined translational and rotational coupling.
As shown in
A sports shoe 1 made according to the invention comprises at least one pressure-sensitive sensor 9a-d for electrotechnical and/or electronic collection of mechanical pressure or forces in or on the sports shoe 1. In particular, at least one sensor 9a-d is specified in or on sports the shoe 1, which can convert mechanical loads, in particular pressures and/or forces between the user's foot and the sports shoe 1 into corresponding electrical signals and/or can provide such signals. The at least one electronic sensor 9a-d can be carried out as an active or passive pressure and/or force sensor. Expediently, the at least one sensor 9a-d is carried out as a pressure-sensitive resistor element and/or as a working detector according to the resistive and/or ohmic operating principle. In the process, various pressures that affect sensor 9a-d will be depicted as various electrical resistance values that can then be differentiated and/or detected by electrical signals. In accordance with an advantageous embodiment, at least one of the pressure-sensitive sensors 9a-d of the sports shoe 1, in particular on its liner 3, would take the form of a textile pressure sensor that has a relatively high flexibility and/or adaptability with regard to the three dimensional form of a liner 3 and/or with regard to the contours of the shape of a foot. Such pressure-sensitive sensors 9a-d are also known as “textile sensors” and are well suited for placement on and/or for integration in soft elastic or textile objects, especially with regard to the liner 3 of the generic sports shoe 1. However, it is also possible that at least one of the sensors 9a-d could be supplied by a pressure sensor that works under the piezoelectric operating principle.
In accordance with a practical execution, at least one sensor 9a can be positioned in the frontal portion of the sole of liner 3, this frontal portion being closest to the balls of the toes and/or the front portion of a user's foot when the sports shoe 1 is being used and/or utilized.
In addition, at least one pressure-sensitive sensor 9b can be positioned in the rear sole portion of the liner 3, which is arranged and/or can be arranged closest to the heel bone of the user.
Through combined evaluation of the pressure signals initiating from and/or provided by the sensors 9a and 9b, sensor-generated conclusions can be drawn especially about the weight distribution and/or the so-called balance of the user. The sensor-generated collection of the user's weight distribution with regard to the forefoot and/or the heel bone is particularly important and relevant in connection with ski boots for practicing alpine skiing, as it allows the respective weight distribution and/or the dynamic shifts in weight of the user to be detected.
In accordance with an additional alternative or combined design, at least one pressure-sensitive sensor 9c can be located in and/or on the liner 3, which records pressure forces and/or loads that act on the lower leg and/or shinbone portion of a user. Expediently, this sensor 9c, as schematically depicted in
In accordance with an advantageous measure, it can also be provided for that at least one pressure-sensitive sensor 9d in the rear portion of the shaft of the liner 3 is provided, as shown in
The description in accordance with
The respective pressures between the foot of the user and the sports shoe 1 or between the sports shoe 1 and/or the lower surface, such as a sporting device coupled with the sports shoe 1, can thus be recorded electronically and/or with sensors through at least one sensor 9a-d and evaluated and/or monitored through one of the evaluation electronics systems described below.
To be able to optimally accomplish this data technology evaluation and/or assessment, it is expedient for the sports shoe 1 to have at least one radio transmission communication interface 11. This radio-equipped communication interface 11 is specified for wireless transmission of pressure signals and/or pressure related data collected by the at least one pressure-sensitive sensor 9a-d. In this respect, the radio-equipped communication interface 11 is equipped for close range signal and/or data transmission, which means for a maximum transmission distance of up to 100 m, ideally of up to 3 m. In the process, it is expedient for the radio-equipped communication interface 11 of the sports shoe 1 to be equipped for signal or data transmission under the Bluetooth, ZigBee, NFC, or WiFi standard. RFID communication systems are also possible in this context. The significant element is that this radio-equipped communication interface 11 of the sports shoe 1 is compatible with a standardized radio-equipped communication interface 12 on at least one standardized electronic evaluation device 13. The communication interface 11 on the sports shoe 1 is particularly designed for data technology communication with a corresponding communication interface 12 on an external, preferably mobile, electronic evaluation device 13. The signal and/or data transmission can thus occur unidirectionally from the communication interface 11 in the direction of communication interface 12 of evaluation device 13. However, there would preferably be bidirectional data communication between the shoe-side communication interface 11 and the external, evaluation-side communication interface 12, as indicated in
The electronic, preferably mobile evaluation device 13 is preferably realized by a standard commercial mobile computing unit 14, in particular defined by a smartphone 15, as depicted in
In the process, it can be expedient if the radio-equipped communication interface 11 of the respective sports shoe 1 is defined by a Bluetooth communication interface, which is compatible with the corresponding standardly implemented Bluetooth communication interface 12 of a standard commercial mobile computing unit 14, in particular to a smartphone 15, to a tablet computer, or to a wearable computer, such as a smartwatch.
As can best be seen in
It is also possible for the signal processing device 16 to have at least one temperature and/or moisture sensor 19 (
The pressure-sensitive sensors 9a-d can be carried out as a pressure and/or voltage transformer, while an optional temperature and/or humidity sensor 19 can also be understood as a corresponding converter and/or transformer.
The electronic signal processing device 16 on the sports shoe 1 of a user is also coupled with the signal of the radio-equipped communication interface 11 explained above and/or comprises the electronic signal processing device 16 of this radio-equipped communication interface 11. In accordance with a typical embodiment, as depicted in
The signal processing device 16 also comprises at least one storage device for system data and/or operating conditions. The storage of such data can occur alternatively or in combination on the user, in particular by means of their mobile computing device 14, such as in their smartphone 15, and/or through a storage device accessed through a data network (cloud storage).
The electronic and/or electrotechnical components of the signal processing device 16 are ideally housed in a housing 22. In contrast, in particular the pressure-sensitive sensors 9a-d are externally positioned with regard to the housing 22 and are line-connected and/or can be connected via the electrical cable connections 17a-d named above—see
In accordance with a practical embodiment, a sports shoe 1, in particular a ski boot is specified, which sports shoe 1 comprises a lower boot portion 27 to receive the foot of a user and an upper boot portion 28 to receive the lower leg of the user. The upper boot portion 28 is connected with the lower boot portion 27, such as with a joint, as is depicted in
The depicted sports shoe 1 accordingly comprises a sensor assembly 29, which comprises several distributed pressure-sensitive sensors 9a-d. The sensors 9a-d are each permanently connected or can be connected as needed via at least single-pole, but ideally via two-pole or multipolar cables 17a-d with the electronic signal processing device 16, which is and/or can be fastened directly to the sports shoe 1.
At least two sensors 9a, 9b of sensor assembly 29 are thereby specified in and/or on a sole assembly 30 placed closest to the sole of the user in sports shoe 1. At least one first sensor 9a is thereby positioned in the front foot portion 31 of the sole assembly 30 of the sports shoe 1 and at least one second sensor 9b is positioned in the heel portion 32 of the sole assembly 30. With respect to a sole length axis 33, the front foot portion 31 can take up approximately one third of the length of the sole, while the heel portion 32 likewise takes up approximately one third of the length of the sole.
It can be expedient, if one single first sensor 9a is specified, for it to be arranged primarily or entirely off center to the sole length axis 33, in particular closer to the inside of the sports shoe 1, as can be seen in
It can also be expedient for the sole assembly 30 to only have a single second sensor 9b in the heel portion 32, which should be positioned as centrally as possible with regard to the sole length axis 33, as is schematically depicted in
The individual sensors 9a-d are connected and/or can be electrically connected with the signal processing device 16 via single-pole or multipolar cables 17a-d. This electrical connection is either permanent or can be connected and removed as needed. In the process, it is preferred for the collected signals of the individual sensors 9a-d to be connected to the shoe-side signal processing device 16 through separate electrical signal cables, to allow specific evaluation of the respective pressure and/or forces ratios in the areas of the sensors 9a-d to be performed.
In the process, the at least one first sensor 9a at the front portion 31 of the sole assembly 30 is connected with the at least one second sensor 9b in the heel portion 32 of the sole assembly 30 via a multipolar flexible flat cable 34a. This means that the cable 17a, b between the first sensor 9a and the second sensor 9b of sole assembly 30 is embodied and/or implemented by means of a multipolar flexible flat cable 34a. In the process, the essential element is that the multipolar flexible flat cable 34a is carried out with an adjustable length, in particular can be changed as needed with regard to its length inside certain limits, such that the multipolar flexible flat cable 34a is adjustable to the optimal distance for recording technology 35 between the at least one first sensor 9a and the at least one second sensor 9b, and in particular can be adjusted to different sole lengths 36. This adaptability to various sole lengths 36 is only expedient and/or necessary preferentially during the manufacturing process of the sports shoe 1 and/or the liner 3. After the sensors 9a, 9b are attached in the area of the sole assembly 30, alteration of distance 35 between sensors 9a and 9b is fundamentally no longer necessary and/or desired. Through these measures, an adjustment and/or optimization of sensor assembly 29 can be efficiently and advantageously achieved in sole assembly 30 with regard to various shoe sizes and/or within defined shoe size fields. This thus facilitates optimal sensor recording conditions and simultaneously supports cost-optimized construction, according to which such a certain, pre-constructed sensor assembly 29 can be used and/or applied for many different sports shoes 1 with various shoe lengths 36.
Accordingly, the sensor assembly 29 in and/or on sports shoe 1 can apply for the additional sensors 9c and/or 9d. In particular, it can be specified that at least one third or fourth sensor 9c, 9d in the upper boot portion 28 can be connected with the at least one first or second sensor 9a, 9b on sole assembly 30 of sports shoe 1 via a multipolar flexible flat cable 34b and/or 34c. At least one of these multipolar flexible flat cables 34b, 34c between the upper boot portion 28 and the lower boot portion 27 can have adjustable lengths as needed. Through this adaptability in length, it is ensured that a distance 35b and/or 35c between the at least one third or fourth sensor 9c, 9d in the upper boot portion 28 and the at least one first or second sensor 9a, 9b in the sole assembly 30 of the sports shoe 1 can be changed as needed, in particular in the upper boot portion 28 to different height dimensions 37 of different models. Accordingly, optimal sensor collection of the force and/or pressure effects occurring in and/or on the sports shoe 1 can be ensured. This also ensures the most cost-effective implementation of the corresponding sensor system in many different, model and/or shoe-size variations of the sports shoe 1. The manufacturing process of sports shoes 1 with the indicated sensor system 29 can thus be implemented cost-efficiently and reliably.

The depicted embodiment of the sensor assembly 29 also comprises a flexible flat cable 34c, which constitutes a third flexible flat cable portion. This flexible flat cable 34c and/or the corresponding third flexible flat cable portion extends between the at least one first sensor 9a and the at least one third sensor 9c. This third sensor 9c is ideally positioned in a tongue portion 47 of tongue 10 of the sports shoe 1 placed close to the user's shin.
The depicted embodiment of sensor assembly 29 comprises one more flexible flat cable 34b, which defines a fourth flexible flat cable portion, which extends between the at least one second sensor 9b and the at least one fourth sensor 9d. In the implementation condition of sensor system 29, this fourth sensor 9d is positioned in a calf portion 48 of the sports shoe 1 placed close to the user's calf.
Sensor assembly 29 can also comprise a flexible flat cable 34d, which defines a fifth flexible flat cable portion, which extends between the at least one fourth sensor 9d and the central connector interface 23 of the sports shoe. In the process, it is advantageous for connector interface 23 to be per se formed by flexible flat cable 34d and to therefore have several electrical contact points 49 in its end portion for this purpose, an example of which can be seen in
In accordance with an expedient embodiment depicted in
In
In the process, the at least one pressure and/or force-sensitive sensor 9a, 9b in the front foot portion 31 and in the heel portion 32 are specified. There also is at least one force and/or pressure-sensitive sensor 9d in the calf portion 48 of the sports shoe 1. The sensors 9a, b, and d are serially connected and/or coupled with each other in a sequence via flexible flat cable 34a. Between the sensors 9a, b, flexible flat cable portions 38′ and 38″ are specified, which can be adjusted to the positions respectively viewed as optimal for sensors 9a, b through its overlapping width 39a.
In contrast, a flexible flat cable 34b is specified in the area between sensors 9b and 9d, which compensates for changing lengths and/or deformations while sports shoe 1 is being used. In particular, it is specified that at least one of the sensors 9a-d is permanently connected, specifically adhered to the sports shoe 1. Within the respective connected flexible flat cables 34a, b, at least one adjustment portion 50 is specified. As an example, the adjustment portion 50 is formed between the two sensors 9b and 9d fixedly and/or permanently connected to the sports shoe 1. In the process, the at least one adjustment portion 50 within flexible flat cable 34b also serves to compensate for and/or take up changes in distance between at least two sensors 9a-d, in particular between sensors 9b and 9d, in the course of use and the resulting elastic deformation of sports shoe 1 caused by the forces exerted. In one example, this adjustment portion 50 would facilitate a variation in distance when the user of the sports shoe 1 shifts their stance, allowing overstraining and/or disproportionate tensile loads on the flexible flat cable 34b to be avoided.

In accordance with an expedient design, it is specified that at least one of the flexible flat cables 34a, b, c comprises a carrier film 45 made of a polyurethane-elastomer or a silicon material. The electric track 46 positioned, specifically printed, on it can be created with a printing ink that contains particles of silver or carbon. This allows at least one of the flexible flat cables 34a, b, c to carried out in such a way that it can elastically extend and contract along its length. In particularly, this can achieve elasticity of up to 10%, in particular of up to 25% with regard to the initial length and/or with regard to the rest state of a correspondingly designed flexible flat cable 34a, b, c. This means that a quasi integral adjustment portion 50 can be created simply and easily in sensor assembly 29 for the relatively marginal changes in position of sensors 9a-d that occur during the use of sports shoe 1.
