Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects dangerous bending moments of a skier's foot on a transverse axis at a vertical distance consisting of the upper surface of the ski between the ankle bulge and the heel in the longitudinal direction of the ski. and a measuring sensing device for sending out an unlocking signal when the dangerous bending moment is reached, and a shoe fixing and holding device that can be freed by the unlocking signal of the measuring sensing device. , at least two measurement sensors are provided, the first of which is arranged between the ski and the sole at a distance from the transverse axis in the longitudinal direction of the ski, at which distance the shoe A second measurement sensor is likewise arranged between the ski and the sole, which is used to measure the force transmitted to the sole.

The present invention relates to a safety fastening device for skis, which is used to measure the longitudinal force acting on the sole and, if necessary, is provided with a support element integrated into the ski below the transverse axis.

This type of safety fastening device can be found, for example, in German Offenlegungsschrift No. 29
It is known from No. 48277. The starting point of this safety fastening system is that it can be assumed that the weakest part of the skier's foot to be protected against excessive bending moments is approximately above the ankle.

In this safety fastening device, an unlocking signal is generated for the shoe fastening device, which signal is a direct measure of the bending moment acting on the skier's foot at a given point.

In the known safety fastening device, the output signal of the measuring sensor is applied to a calculation circuit, by which a summed unlocking signal is formed. Two longitudinally offset measuring sensors are arranged, which measure the forces acting perpendicularly to the sole. According to another embodiment, only one measuring sensor and a support element integral with the ski are provided, at least approximately below the transverse axis. For longitudinal forces acting on the sole of a ski boot, special measuring elements are required in each case.

According to one family of constructions, the measurement detector grips the sole directly, and according to another family of constructions, a sole plate is arranged between the sole and the measurement sensor.

In all cases, however, each measuring sensor is attached to and supported on the ski independently of another measuring sensor and (also Fi> at least a bearing or support element, so that the effects of the skiing that occur during the sliding of the ski) Erroneous unlocking or failure to unlock due to an erroneous measurement value of the longitudinal force caused by the overall bending is likely to occur.

It is therefore an object of the present invention to eliminate these practical disadvantages.

This aim, according to the invention, is to maintain the members, which hold the ski boot in the longitudinal direction of the ski and between which the longitudinal forces are measured, in a rigid connection to each other, at least in the state of use of the safety fastening device. It is solved by keeping it at Thereby, the forces caused by the overall bending K of the ski are separated from the longitudinal force measurement sensor.

According to a preferred embodiment of the invention, the above-mentioned element for holding the ski boot in the longitudinal direction of the ski is integrally formed on or fixed to a base plate supported on the ski. Particularly when the length of the board is large, it is possible to hold one end of the board fixedly and the other end movably on the ski, avoiding the use of undesirable reinforcements of the ski that would impair the running properties of the ski. Make it.

The preferred embodiment of the invention shown in the accompanying drawings will now be described in more detail. The safety fastening device for skis, which will be described in detail below, accommodates a ski boot 1 as shown in FIG. is held in its sole 2 in the conventional manner.

The skier's feet are indicated by the number 3. Bearing in mind that the weakest point of a skier's foot is above the ankle, it is assumed that the transverse axis 4 lies at this point. The horizontal axis 4 is located between the ankle bulge and the heel when viewed in the longitudinal direction of the ski 7.

The ski safety fastening device according to the invention has a base plate 5,
The base plate 5 is screwed onto the ski 7 in a manner not shown in the region of the front sole holder 6. On the contrary, the rear end of the base plate 5 is simply prevented from lifting on the ski 7; it extends through a slot 9 in the base plate parallel to the ski 7 and is integral with the ski 7. It is represented by the horizontal axis 8 held at . The rear sole holder 10 is swingably supported on the base plate 5 at a point 11 and is moored in its use position according to FIG. are firmly connected to each other through the

A first measurement sensor 12 in the form of a pressure sensor 12 is connected to the sole 2 of the shoe.
and the gripping portion 14 of the rear sole holder 10 that grips the upper rear end.

Parallel to this, in the area of the ankle bulge, another pressure sensor 15 is arranged between the sole 2 of the ski boot and the base plate 5. A further pressure sensor 16 is arranged between the front sole holder 6 and the front end surface of the sole 2. sole 2
The longitudinal forces acting on these pressure sensors 14.
15.16.

The output signal of the pressure sensor 14.15.16 is processed by a corresponding processing device of the safety fastening device in any suitable manner not falling within the scope of the invention, and is processed when a dangerous bending moment is reached. A lock release signal is generated, thereby releasing the rear sole holder 10, so that the holder 1
0 swings around its pivot point 11, and the boot 1 can be freed from the safety fastening device.

Due to the construction of the ski safety fastening device according to the invention, a general bending of the ski 7 caused, for example, by skiing on depressed terrain, does not increase the forces acting on the pressure sensor 16.

The ski safety fastening device according to the embodiment shown in FIG.
Basically, since this corresponds to the apparatus shown in FIG. 1, the same members as those shown in FIG. 1 are designated by the same reference numerals as in FIG. The embodiment of FIG. 2 is simplified in that the pressure sensor 15, which measures the force acting at right angles to the upper surface of the ski, is omitted in the example of FIG. In order to support the sole 2 of the ski boot instead, the horizontal axis II
A support member 17 is arranged on the substrate 5 at least approximately below M4.

The ski safety fastening device according to the invention shown in FIG. 6 has a sole plate 18 on which the ski boot l is supported over its entire length.

Each longitudinal side of the ski boot l has one opening/closing jaw 19.
It is held on the shoe sole plate 18.

Each opening/closing jaw 19 is supported on the sole plate 18 so as to be able to pivot outwardly about a longitudinal axis parallel to the ski 7. The opening/closing jaw 19Fi is anchored in its use position. As with the sides described above, the boot retention device becomes free when an unlock signal is applied. In all embodiments, the ski boot fixing and holding device is constructed in such a way that it can be detached from the safety fastening device at the skier's will, such as at the end of a ski run.

The sole plate 18 is connected to a base plate 21 via a horizontal transverse axis 20.The rear end of the sole plate 18 is connected via two measuring sensors arranged at right angles to each other and formed as pressure sensors 22,23. It is in contact with the substrate 5.

As with the above-mentioned sides, the front end of the board 21 is held fixedly and the rear end movably on the ski 7. According to this embodiment, since the length of the base plate 5 is relatively short, if the movable bearing is omitted, the support for the ski becomes very small, but the structure of the safety fastening device is simplified.

Of course, a front sole holder and a rear sole holder may be used in place of the opening/closing jaws 19, but in that case, it is desirable that the rear sole holder be swingable and tethered when in use.
