Intelligent safety binding with synchronized triggering and modular power supply

Abstract

Safety binding for sporty board sports equipment such as wakeboards, snowboards or similar, characterized in that the connection between the sports equipment and the shoe is electrically or electromagnetically locked to enable controlled release in critical load situations.

Description

1. Technical field:

[0001] The invention relates to a safety binding for connecting shoes to sporty board sports equipment such as wakeboards, snowboards, kiteboards, water skis, or similar devices. The invention serves to improve safety and comfort, in particular through controlled and synchronized release under critical loads and intuitive entry and exit. 2. State of the art:

[0002] Conventional bindings for wakeboards or snowboards are known to mechanically fix the feet using straps or rigid brackets. A safety release mechanism for overload or twisting is usually not included. While bindings with release mechanisms exist in winter sports (e.g., ski bindings), these are generally mechanically constructed and not optimized for torsional or combined loads.

[0003] A previously published German patent, DE102013013789A1, describes a safety-relevant binding device with a magnetic connection. However, this requires external aids for triggering and does not provide for synchronous, bilateral release. Furthermore, it does not describe any dynamic sensor technology with adjustable thresholds or wireless communication. 3. Object of the invention:

[0004] The invention aims to provide a safety bond that: • securely connects both feet to a board sports device, • automatically triggers under supercritical load, • releases both feet simultaneously, • has a reliable electronic or electromagnetic locking mechanism, • is comfortable to use, • modularly adaptable to different shoe sizes, • and includes a weatherproof and waterproof power supply (e.g. inductive or replaceable) 4. Solution to the task:

[0005] The task is accomplished through a safety interlock with the features specified in the protection claims. In particular, continuous monitoring of relevant mechanical stress parameters (e.g., torsion, tension, bending) is achieved through electronic sensors. When definable threshold values ​​are exceeded, the sensors send a trigger signal to the locking units.

[0006] Synchronization is achieved through signal transmission between the left and right bindings, either wirelessly or via a mechanical connection. Locking elements (e.g., conical bolts or clamps) secure the boot to the board without play during operation and can be triggered electrically, electromagnetically, or mechanically.

[0007] Power is supplied via a replaceable battery or an inductive charging solution. Optionally, the status can be viewed or configured via an app interface. 5. Advantages of the invention: • Increased driving and landing safety (e.g. through synchronous triggering) • More comfortable and faster entry thanks to automated or manual activation of the locking mechanism, for example at the push of a button. • Modular design suitable for different shoe sizes • Electronics designed to be “failsafe”: Locking mechanism remains closed when power is off. • Manual emergency release possible at any time. Suitable for use in various sports (summer and winter). • Minimizing typical injury risks such as knee and ankle injuries 6. Example of implementation:

[0008] A wakeboard is equipped with two binding units. Each binding unit contains four conical locking pins that engage with corresponding sleeves in the boot sole via electromagnetic actuators. Sensors measure torsion and tensile load. As soon as a threshold is exceeded, the locking units on both sides release the pins. The pins retract instantly – the boot is free. Power is supplied via inductive charging coils in the binding base. A manual emergency release is also provided.
