Designation "ski safety fastening".

Labeling;

The origins patent application suggests ski bindings magnetic adhesion points, especially in connection with mechanical ski safety bindings. In this additional patent application is now a common application of permanent and electromagnetic traps as only attachment of boot and ski board suggested that has very significant advantages over safety bindings, which exert strong longitudinal forces on the shoe sole, because it frees the skier from the completely rigid shoes, which have been proven to be harmful to health.

The sole magnetic adhesive binding allows the use of sturdy but more comfortable shoes with flexible soles .. ·· Therefore, the innovation is particularly suitable for children's skis. The new binding is easy to close and separate. Individual grading of the adhesive forces can be obtained by selection of the - permanent magnet material, the volume and the pole face and the other by the power supplied to the electromagnet power reaches werden.Die with great adhesive strength loss associated tuning of the combustion by changing the air gap between the pole faces is unnecessary.

The invention consists in that for the generation of the adhesive forces In addition to building magnets, electromagnets are also arranged in such a way that permanent magnets are used for the front part of the shoe sole and electromagnetic traps are provided for the heel surface. The anchor plates are both types of magnet preferably separated from one another in such a way that the plate is detachably attached to the shoe at the front and firmly attached to the heel at the rear is. The electromagnet is preferably fastened on a swiveling base plate in such a way that the shoe heel can be raised.

The permanent magnets are firmly attached to the ski board. The associated anchor plate has a 'fastening device at the top for quick coupling of plate and shoe, e.g. a Dovetail strip matching a groove in the front sole.

Putting on the ski is extremely easy and convenient: when the system is switched off Electromagnets are moved with the shoe into the profile strip on the front anchor, the heel anchor is thought of on the pole face of the electromagnet and switches it on. It is, as it were, the key to the ski binding. It is advantageous to also connect the anchor plate on the shoe with a centrally attached dovetail bar on the heel, because this connection reduces the overturning moment that occurs when skiing on the magnetic trapping points.

The iron of the electromagnet can be wholly or partially laminated, which can shorten the detachment time. In other cases it may be useful to use an iron with such a large remanence that the attachment can just be detached. Then the electromagnet only needs to be switched on if the binding is expected to be subjected to great stress. When the ski safety fastening is impacted from the front, sliding occurs between the magnet and the adhesive plates, which is limited by an elastic buffer to reduce the impact. The detachment of the boot from the ski board in the event of a fall is complete, and it is impossible to get caught on binding components. The two anchors and the lanyard, which can also be designed as a power supply, remain on the shoe if the power source cannot be accommodated on the ski board itself.

The three figures show an example of the above-mentioned ski safety connection The side view and the bottom plan view show the z.u. three-pole Iron 1 of the electromagnet, its excitation coil 2 and its pivotable base plate 3 with the pivot point 4. The heel-side Anchor in the form of a steel plate 5 is attached to the heel with a dovetail bar, for example.

The front anchor 6 adheres to permanent pot maggots 7, 8. Of the Magnetic material is labeled 8. The shoe sole has the front a groove into which a dovetail bar fastened on the anchor 6 " When putting on the shoe, first slide the toe of the shoe into the groin 9, then put on the heel the electromagnet 1, 2 and excites it. The ski is applied. The greater adhesive force, as it should be, the Section A-B shows the swiveling bridge 3 with pivot 4 on which the electromagnet is fixed. 6 is the anchor of the permanent magnets with the bar 9 and 10 the ski board on which the permanent magnets 7,8 are firmly attached. The elastic buffer has the Hummer 11. The current flow the coil 2 is indicated by arrows and in the upper picture by the arrowhead or arrow end.

See and. for. Jk * eri paragraph electromagnetic liability vorhajid-ön is. 2). Sfcisicherheitsbestigung-according to patent claim 1, d.g., that the anchor plates of both types of magnet are preferably separated from each other and the plate for the front sole respectively Easily detachable for the permanent magnets, but the plate for the sheet metal magnets is firmly attached Paragraph is attached. 3). Ski safety fastening according to claims 1 and 2, i.e. that the electromagnet is mounted on a swiveling base plate in such a way that the shoe heel can be raised. 4). Ski safety fastening according to claims 1 to 3, i.e. that for quick coupling of the front sole with the anchor plate a longitudinal, centrally mounted swallow tail strip or the like, to match a corresponding hat in the front seat, serves. 3 09R4B /0.6? 7th
