Description

Die Erfindung bezieht sich auf eine Sicherheits-Halteeinrichtung für einen Schuh, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a safety holding device for a shoe, according to the preamble of claim 1.

Eine solche Halteeinrichtung wurde z.B. durch die DE-OS 33 07 003 bekannt. Gemäß dieser bekannten Lösung ist der Meßwertaufnehmer an der Unterseite der einstückig mit der Außenschale verbundenen Sohle angeordnet, wodurch sich Kraft-Nebenschlüsse ergeben, die von sich ändernden Reibungskoeffizienten, z.B. durch Eis- und Schneeansatz, beeinflußt sind und es daher zu einer Verfälschung der auf den Schiläufer einwirkenden Kräfte bei deren Erfassung kommt.Such a holding device was e.g. known from DE-OS 33 07 003. According to this known solution, 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.

Weiters wurde durch die Zeitschrift "Journal of Biomechanical Engineering" Vol. 103, Seiten 138ff und die Zeitschrift "Messtechnische Briefe, 11. Jhg. (1975) Heft 3, Seiten 59 bis 62 Sicherheits-Halteeinrichtungen für Meß- und Prüfzwecke vorgeschlagen, wobei in einer an der Sohle eines üblichen Schischuhs angebrachten Meßsohle eine Reihe von Meßfühlern zur Erfassung der beim Alpin-Schifahren auf den Fuß des Schiläufers einwirkenden Belastungen, wie z.B. Kräfte und Momente angeordnet waren. Diese Meßfühler waren über galvanische Leitungen mit einer in einem Rucksack untergebrachten Auswerteeinrichtung verbunden.Furthermore, the magazine "Journal of Biomechanical Engineering" Vol. 103, pages 138ff and the magazine "Messtechnische Briefe, 11. Jhg. (1975) No. 3, pages 59 to 62 suggested safety holding devices for measuring and testing purposes, whereby in a measuring sole attached to the sole of a conventional ski boot, a number of measuring sensors for detecting the loads, such as forces and moments, which were exerted on the foot of the skier during alpine skiing, were connected via galvanic lines to an evaluation device accommodated in a backpack .

Eine solche Einrichtung ist jedoch lediglich für Versuche und Messungen geeignet, nicht aber für eine Sportausübung auf breiter Basis.However, such a device is only suitable for tests and measurements, but not for a wide range of sports.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Sicherheits-Halteeinrichtung der eingangs erwähnten Art vorzuschlagen, bei der eine Beeinflussung der erfaßten Belastungswerte durch sich ändernde Reibungskoeffizienten bei Kraft-Nebenschlüssen sicher vermieden sind.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.

Erfindungsgemäß wird dies bei einer Einrichtung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention this is achieved in a device of the type mentioned at the outset by the characterizing features of claim 1.

Durch die vorgeschlagenen Maßnahmen ergibt sich der Vorteil, daß die Erfassung der auf den Schiläufer einwirkenden Kräfte durch keinerlei von Veränderungen der Reibungskoeffizienten beeinflußten Kraft-Nebenschlüssen verfälscht wird.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.

Bei einer erfindungsgemäßen Sicherheitshalteeinrichtung, bei der die Auswerteschaltung in einer Höhlung des Schuhs angeordnet ist, ergibt sich durch die Merkmale des Anspruches 2 der Vorteil, daß das Eindringen von Feuchtigkeit in die Höhlung leicht verhindert werden kann. Dabei ist auch zu berücksichtigen, daß die Sohle eines Schuhs, insbesondere eines Schi- oder Bergschuhs in der Regel aus einem Kunststoff hergestellt ist und es bei solchen Materialien zu Ermüdungs- oder Alterungsrissen, insbesondere im Bereich von Rändern, kommen kann, über die Feuchtigkeit in das Innere der Höhlung gelangen könnte. Gegen das Innere des Schuhs zu läßt sich diese Gefahr durch Verwendung saugfähiger Materialien zur Abdeckung der Öffnung der Höhlung leicht beherrschen.In a safety holding device according to the invention, in which the evaluation circuit is arranged in a cavity of the shoe, the features of claim 2 result in the advantage that the penetration of moisture into the cavity can easily be prevented. It should also be taken into account that 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.

Grundsätzlich ist es aber auch möglich die Sensorik, die Auswerteschaltung und bzw. oder die Energieversorgung z.B. im Boden der Außenschale einzugießen, sodaß die Höhlung vollständig ausgefüllt wird.In principle, however, it is also possible to use 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.

Durch die Merkmale des Anspruches 3 wird erreicht, daß die Temperatur im Bereich der Schaltung(en) weitgehend konstant gehalten werden kann. Außerdem wird auch eine Kältebrücke zum Schuhinneren hin vermieden und dadurch der Tragekomfort erhöht. Außerdem wird durch die Verminderung der Temperaturschwankungen im Bereich der Auswerteschaltung eine erhebliche Verbesserung der Meßgenauigkeit und bzw. oder eine Verringerung des schaltungstechnischen Aufwandes erreicht.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.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein. daß die Höhlung zur Aufnahme der Schaltung(en) mit einem schockabsorbierenden, bzw. stoßabsorbierenden Material ausgekleidet ist, um eine Belastung der Schaltung(en), insbesondere deren Leiterplatten und Lötstellen durch Vibrationen und Stöße weitgehend zu vermeiden.According to a further feature of the invention can be provided. that 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.

Die Erfindung wird nun anhand der Zeichnung, die ein Ausführungsbeispiel zeigt, näher erläutert. Dabei zeigen:

  • Fig. 1 schematisch einen Längsschnitt durch einen Schuh, der für eine erfindungsgemäße Sicherheits-Halteeinrichtung vorgesehen ist,
  • Fig. 2 schematisch einen Schnitt parallel zur Aufstandsebene des Schuhs im Bereich des Bodens seiner Außenschale und
  • Fig. 3 ein Detail in größerem Maßstab aus der Fig. 1.
The invention will now be explained in more detail with reference to the drawing, which shows an embodiment. Show:
  • 1 schematically shows a longitudinal section through a shoe which is provided for a safety holding device according to the invention,
  • Fig. 2 shows schematically a section parallel to the footprint of the shoe in the region of the bottom of its outer shell and
  • 3 shows a detail on a larger scale from FIG. 1.

Die Fig. 1 und 2 zeigen eine Schischuh 1, der für die Aufnahme in einer erfindungsgemäßen Sicherheits-Halteeinrichtung vorgesehen. Dabei ist der dargestellte Schuh 1 für eine Aufnahme zwischen zwei Backen einer Schibindung vorgesehen, von denen mindestens einer über ein entsprechendes Signal auslösbar ist, um willkürlich oder im Falle von zu großen Belastungen des Schiläufers unwillkürlich den Schuh freizugeben, sodaß dieser freigegeben wird.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.

Aus der Fig. 1 und 2 ist zu ersehen, daß der Schuh 1 eine Außenschale 22 aufweist, die einstückig mit einem Boden 24 ausgebildet ist. Die Unterseite des Bodens 24 der Außenschale 22 ist über eine elastische Zwischenschicht 23 mit einer Sohle 20 verbunden, die in üblicher Weise ausgebildet ist um von üblichen Backen einer Sicherheits-Schibindung gehalten werden zu können. Dabei wird jede auf die Sohle 20 einwirkende Krafteinwirkung über die elastische Zwischenschicht 23 auf den Boden 24 der Außenschale 22 und damit auf den Fuß des Benutzers übertragen, bzw. jede vom Fuß ausgeübte Krafteinleitung wird über die Zwischenschichte 23 auf die Backen einer nicht dargestellten Schibindung, bzw. auf einen Schi übertragen. Es ergibt sich daher eine in geringem Ausmaß schwimmende Halterung der Außenschale 22 in der eine Vertiefung aufweisenden Sohle 20. Bei Kenntnis der Federkonstante der elastischen Zwischenschicht 23 kann daher über den Verschiebeweg zwischen Boden 24 und Sohle 20 auf die Belastung rückgeschlossen werden.1 and 2 that 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. 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. There is therefore a slight floating mounting of the outer shell 22 in the recess 20 having a recess. If the spring constant of the elastic intermediate layer 23 is known, the load can therefore be deduced from the displacement path between the base 24 and the sole 20.

Im Boden 24 der Außenschale 22 des Schuhs 1 ist eine Höhlung 21 angeordnet ist, in der sich eine Batterie 2 und eine Leiterplatte 18 befinden, auf der eine Signalaufbereitungs- und eine Auswerteschaltung angeordnet sind. Wie insbesondere aus der Fig. 1 zu ersehen ist, ist der Boden der Höhlung 21, die sich im Boden 24 der Außenschale 22 befindet, mit einer thermisch isolierenden Schicht 15 ausgelegt, unter der sich noch eine schockabsorbierende, bzw. stoßdämpfende Schicht 16 befindet. Diese beiden Schichten erstrecken sich auch über die Seitenwände der Höhlung 21, die mit einer Abdeckung 17 gegen das Innere der Außenschale 22 zu abgedeckt ist, wobei die Abdeckung 17 an ihrer dem Inneren der Höhlung 21 zugekehrten Seite mit einer schockabsorbierenden Schicht 16 belegt ist. Eine thermisch isolierende Schicht fehlt jedoch bei der Abdeckung 17, um eben durch die Fußwärme des Benutzers eine Stabilisierung der in der Höhlung 21 herrschenden Temperatur zu erreichen.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. As can be seen in particular from FIG. 1, 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. However, 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.

Wie aus den Fig. 1 und 2 weiter zu ersehen ist, weist der Boden 24 der Außenschale 22 an seiner Unterseite eine Vertiefung 14 auf, in der Aufnehmer S1, S2 zur Erfassung der einwirkenden Kräfte angeordnet sind. Dabei sind einander zugeordnete Teile der Aufnehmer S1, S2 zur Bestimmung der Belastung in der y- und z-Richtung an den einander zugekehrten Seiten der Sohle 20 und des Bodens 24 der Außenschale befestigt. Diese Aufnehmer können im Prinzip beliebig ausgebildet sein, wesentlich ist lediglich, daß diese eine Relativbewegung zwischen der Sohle 20 und der Außenschale 22 erfassen können, welche Bewegung auf Grund der bekannten Elastizitätskonstante der Schicht 23 ein Maß für die auftretenden Belastungen ist.As can also be seen from FIGS. 1 and 2, 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. 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. In principle, 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.

Es können auch eine Einheit bildende Meßwertaufnehmer vorgesehen sein. Wesentlich ist lediglich, daß der bzw. die Meßwertaufnehmer zumindest in einer Kraftrichtung bzw. Richtung einer Relativbewegung Kräfte bzw. Bewegungen erfassen.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.

Die für die Auswerteschaltung erforderlichen persönlichen Daten des Benutzers können in üblicher Weise durch Steller z.B. einstellbare Widerstände, oder in Speicherschaltungen eingegeben werden, um die Abgabe eines Auslösebefehls erst bei Vorliegen gefährlicher Belastungen zu ermöglichen, wobei je nach dem gewählten Algorithmus, nach dem die Auswerteschaltung die von Aufnehmern generierten Signale verarbeitet, auch die Einwirkdauer dieser Belastungen oder deren Änderung über die Zeit berücksichtigt werden kann.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.

Weiters können dabei auch Umgebungsbedingungen, wie die Außentemperatur und die Temperatur im Innenraum des Schuhs berücksichtigt werden.Furthermore, environmental conditions such as the outside temperature and the temperature inside the shoe can also be taken into account.

Bei der Ausführungsform nach der Fig. 1 und 2 sind die Temperaturfühler T1 und T2 an der dem Inneren des Fußraumes der Außenschale zugekehrten Seite des Bodens 24 derselben und an der Außenseite der Außenschale im Fersenbereich des Schuhs 1 angeordnet.In the embodiment according to FIGS. 1 and 2, 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.

Damit kann sowohl die Temperatur im Inneren des Schuhs 1, die gleichzeitig auch einen sehr guten Anhaltspunkt für eine allfällige Unterkühlung des Benutzers liefern kann, welche Auswirkungen auf die Belastbarkeit der Knochen des Benutzers hat, wie auch die Außentemperatur erfaßt werden, welche letztere ebenfalls in einem gewissen Grad die Belastbarkeit des Benutzers beeinflußt. Diese Werte können durch die Auswerteschaltung, die im Bedarfsfall ein Signal zur unwillkürlichen Auslösung der Halteeinrichtung liefert, berücksichtigt werden.This means that both the temperature inside the shoe 1, which at the same time can provide a very good indication of any hypothermia of the user, which has an impact on the resilience of the user's bones, as well as the outside temperature, the latter also in one affects the user's resilience to a certain degree. These values can be taken into account by the evaluation circuit, which if necessary provides a signal for the involuntary triggering of the holding device.

Die Temperaturfühler T1, T2, wie auch die Aufnehmer S1, S2 sind mit der Signalaufbereitungsschaltung verbunden, die eine entsprechende Signalformung, vorzugsweise eine Digitalisierung, der einlangenden Signale bewirkt und diese der Auswerteschaltung zuleitet, die sie nach einem vorgegebenen Algorithmus nach dem Vorhandensein einer gefährlichen Belastung untersucht, wobei jedoch im Prinzip jede Art der Signalformung möglich ist. Ist eine gefährliche Belastung gegeben, so gibt die Auswerteschaltung ein Auslösesignal an den Sender 2a, 2b ab, die im Zehen- und im Fersenbereich der sohle 20 angeordnet sind. Diese übertragen das Auslösesignal zu einem Auslösemechanismus eines nicht dargestellten Backens einer Schibindung, die den Schuh frei gibt. Dabei genügt die Übertragung digitaler Signale.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.
