Definitions

  • the invention relates to a safety holding device for a shoe, according to the preamble of claim 1.
  • Such a holding device was e.g. known from DE-OS 33 07 003.
  • the transducer is arranged on the underside of the sole which is integrally connected to the outer shell, which results in force shunts which are caused by changing coefficients of friction, e.g. are influenced by ice and snow, and therefore there is a distortion of the forces acting on the skier when they are recorded.
  • the aim of the invention is to avoid these disadvantages and to propose a safety holding device of the type mentioned at the outset, in which an influencing of the detected load values by changing friction coefficients in the case of force shunts is reliably avoided.
  • the proposed measures have the advantage that the detection of the forces acting on the skier is not falsified by any force shunts that are not influenced by changes in the coefficient of friction.
  • the features of claim 2 result in the advantage that the penetration of moisture into the cavity can easily be prevented.
  • the sole of a shoe in particular a ski or mountain shoe, is generally made of a plastic and that such materials can cause fatigue or aging cracks, particularly in the area of the edges, through which moisture in get inside the cavity could. This danger can be easily controlled against the inside of the shoe by using absorbent materials to cover the opening of the cavity.
  • the sensors, the evaluation circuit and / or the energy supply e.g. Pour into the bottom of the outer shell so that the cavity is completely filled.
  • the features of claim 3 ensure that the temperature in the region of the circuit (s) can be kept largely constant. In addition, a cold bridge to the inside of the shoe is avoided, which increases comfort. In addition, by reducing the temperature fluctuations in the area of the evaluation circuit, a considerable improvement in the measuring accuracy and / or a reduction in the complexity of the circuitry is achieved.
  • the cavity for receiving the circuit (s) is lined with a shock-absorbing or shock-absorbing material in order to largely avoid stressing the circuit (s), in particular its circuit boards and solder joints, by vibrations and shocks.
  • FIG. 1 and 2 show a ski boot 1, which is provided for inclusion in a safety holding device according to the invention.
  • the shoe 1 shown is provided for a receptacle between two jaws of a ski binding, at least one of which can be triggered by a corresponding signal, in order to involuntarily or in the event of excessive loads on the skier to involuntarily release the shoe, so that it is released.
  • the shoe 1 has an outer shell 22 which is formed in one piece with a bottom 24.
  • the underside of the bottom 24 of the outer shell 22 is connected via an elastic intermediate layer 23 to a sole 20, which is designed in the usual way in order to be able to be held by the usual jaws of a safety ski binding.
  • a sole 20 which is designed in the usual way in order to be able to be held by the usual jaws of a safety ski binding.
  • Each one acts on the sole 20
  • the action of force is transmitted via the elastic intermediate layer 23 to the bottom 24 of the outer shell 22 and thus to the foot of the user, or any force applied by the foot is transmitted via the intermediate layer 23 to the cheeks of a ski binding, not shown, or to a ski.
  • a cavity 21 is arranged in the bottom 24 of the outer shell 22 of the shoe 1, in which there is a battery 2 and a printed circuit board 18 on which a signal conditioning and evaluation circuit are arranged.
  • the bottom of the cavity 21, which is located in the bottom 24 of the outer shell 22, is designed with a thermally insulating layer 15, under which there is still a shock-absorbing or shock-absorbing layer 16.
  • These two layers also extend over the side walls of the cavity 21, which is covered with a cover 17 against the interior of the outer shell 22, the cover 17 being covered on its side facing the interior of the cavity 21 with a shock-absorbing layer 16.
  • there is no thermally insulating layer in the cover 17 in order to stabilize the temperature prevailing in the cavity 21 through the warmth of the foot of the user.
  • the bottom 24 of the outer shell 22 has a depression 14 on its underside, in which sensors S1, S2 are arranged for detecting the forces acting.
  • sensors S1, S2 are arranged for detecting the forces acting.
  • Parts of the transducers S1, S2 which are assigned to one another are attached to the mutually facing sides of the sole 20 and the base 24 of the outer shell for determining the load in the y and z directions.
  • these transducers can be of any design, the only essential thing is that they can detect a relative movement between the sole 20 and the outer shell 22, which movement is a measure of the loads occurring due to the known elastic constant of the layer 23.
  • a measuring transducer forming a unit can also be provided. It is only essential that the sensor or sensors record forces or movements at least in one direction of force or direction of a relative movement.
  • the personal data of the user required for the evaluation circuit can be entered in the usual way by means of actuators, for example adjustable resistors, or in memory circuits in order to enable a triggering command to be given only when dangerous loads are present, depending on the algorithm selected, according to which the evaluation circuit determines the processed signals generated by sensors, the duration of exposure to these loads or their change over time can be taken into account.
  • actuators for example adjustable resistors
  • memory circuits in order to enable a triggering command to be given only when dangerous loads are present, depending on the algorithm selected, according to which the evaluation circuit determines the processed signals generated by sensors, the duration of exposure to these loads or their change over time can be taken into account.
  • the temperature sensors T1 and T2 are arranged on the side of the bottom 24 thereof facing the interior of the foot space of the outer shell and on the outside of the outer shell in the heel region of the shoe 1.
  • the temperature sensors T1, T2, as well as the sensors S1, S2, are connected to the signal processing circuit, which effects a corresponding signal shaping, preferably digitization, of the incoming signals and feeds them to the evaluation circuit, which they use according to a predetermined algorithm after the presence of a dangerous load examined, but in principle any type of signal shaping is possible. If there is a dangerous load, the evaluation circuit emits a trigger signal to the transmitter 2a, 2b, which are arranged in the toe and heel region of the sole 20. These transmit the trigger signal to a trigger mechanism of a baking of a ski binding, not shown, which releases the shoe. The transmission of digital signals is sufficient.
