i Ski edge planer

Up to now, ski edge running surfaces have been filed by hand with body files (up to a maximum of 1 ° in relation to the ski running surface). Only after this step are the side surfaces of the ski edges ground, usually at an angle of 90 to 87 ° with respect to the ski surface. Ski manufacturer have tried grinding | To loosen ski edges by machine. So far, however, no freeze | I found the right way, especially since every ski is tailored.

This object is now achieved according to the invention by a ski edge planer which is characterized by the following features:

(a) a cutting tool for planing or processing the ski edge running surface ,

(b) a first guide (tread guide), |

(c) Rolling elements arranged in the first guide (running surface guide) for rolling the ski edge planer on the ski running surface and

(D) a second guide (ski side surface guide) to the adjacent Guide the ski edge planer along a side surface of the ski.

With regard to a ski to be processed, in the present context between the running surface, the ski edge and the ski side surface and at the ski edge, in turn, between the ski edge running surface and side surface of the ski edge are differentiated. The ski running surface and the ski side surface as well as the ski edge running surface and the side face of the ski edge meet each other at an angle of approximately 90 °. The ski area includes the actual running surface and the ski edge running surfaces flanking it. The side surface of the ski comprises the actual side surface and the ski edge side surface.

According to the invention, a knife which can have one or more cutting edges, for example, can be used as a cutting tool one to four cutting edges. If one of the cutting edges of a knife with more than one cutting edge is worn, then so the other cutting edges can then be used to machine ski edges. With a knife with more than one Cutting edge, it is advantageous if the knife has a T-profile or a double-T-profile, thus approximately the shape of a T or Double T-Elsens. Each of the two wings forms a T a knife edge.

It can be advantageous if the knife in relation to a

- on the second guide (ski side surface guide) with a Side face and

- on the rolling elements as the first guide (running surface guide) with the skis lying against the skiing surface (machining positioning) is arranged in the ski edge planer as follows:

- The surface of the working knife edge facing the ski edge contact surface forms one with the ski edge contact surface acute angle and

- the actual cutting edge of the working knife edge forms an obtuse angle with the actual ski edge in the machining direction.

When a ski touches its tread in the specified manner rests against the rolling elements of the first guide (running surface guide), one can imagine a plane that is affected by the rolling elements together and that with the skiing surface coincides. Furthermore, if the ski is attached to the second guide with one of its side surfaces in the specified manner (ski side surface guide) is applied, see below with regard to the points of contact or points of the second guide (ski side guide) Think of a straight line that is tangent to these points or points (here called the system), the one in the side surface of the ski Based on this, the arrangement of the knife in the ski edge planer can also be defined as follows:

- the surface to be turned towards the ski edge of the working surface The knife edge forms an acute angle with the plane that is tangent to the roller elements;

- The actual cutting edge of the cutting knife edge forms a blunt edge with the straight line in the machining direction Angle that is determined by the system of the second guide (ski side surface guide) is affected; and

- The actual cutter of the working knife edge can move around in relation to the plane tangent to the rolling elements an angle in the range from 0 to a few degrees, e.g. up to 2.

It can be advantageous if one or more magnets are arranged behind the cutting tool in the machining direction, to pick up chips lifted off ski edges. Such magnets can, for example, in the first guide (running surface guide) be arranged. In one embodiment of the invention Ski edge planer is the second guide (ski side surface guide) with one, two or more rolling elements to the adjacent The ski edge planer is guided along (unrolled) along a side surface of the ski.

Rolling elements provided in the first guide (running surface guide) and in the second guide (ski side surface guide)

3417 - 4 -

are not only used to guide the ski edge planer easily along an adjacent ski. They also offer the advantage that chips lifted off the ski edges are not so easily pressed into the white ski running surface.

It may be desirable to process ski edge treads in this way.

i th that the ski edge treads and the actual ski j running surface which is flanked by the two ski edge running surfaces] at an angle in the range of 180 ° or less, both for example cut 180 to 178 °; the ski edge running surfaces should therefore be in one with respect to the actual ski running surface Range from 0 to a few degrees depending, for example | se can be machined depending on 0 to 2 °. -,

Unless you have a continuously swiveling cutting tool in front of f

finds. ^T

For this purpose one can provide that the cutting tool (more precisely: the second guide (ski side surface guide)) is adjacent Rolling element or the rolling elements adjacent to it (if several rolling elements are directly adjacent to it) of the first Guide (running surface guide) transversely to this first guide (running surface guide) or perpendicular to that of the rolling elements jointly tangent plane or perpendicular to the running surface of an adjacent ski steplessly displaceable or displaceable are formed (section Fig. 7a). Accordingly, it can be provided that the rolling element furthest away from the cutting tool or the rolling elements furthest away from it can be continuously displaced transversely to the first guide (running surface guide) are formed (section Fig. 7b). The desired displaceability or displaceability of the rolling elements can be

can also be achieved by the fact that the bearings or the storage of the corresponding rolling elements can be steplessly adjusted in an analogous manner displaceable or displaceable forms (Fig. 7a and 7b).

The above-mentioned relocatability or displaceability can be e.g. achieve that the bearing of the rolling elements comprises an eccentric or adjusting eccentric, the eccentric position lockable is infinitely adjustable.

With regard to the pivoting of the first guide (running surface guide) and a ski resting against its running surface in relation to on each other and with regard to the arrangement of the roll elements to each other and in relation to the ski edge of an adjacent one Skis is also referred to DE patent application P 31 36 082.3 and DE-Gbra application G 81 32 735.8, their disclosure content is included here.

An embodiment of the ski edge planer according to the invention, in which two rolling elements of the first guide (running surface guide) in the vicinity of the second guide (ski side surface guide) and a third rolling element at a greater distance from the Second guide (ski side surface guide) is arranged, can be useful. With such an arrangement of the rolling elements For example, the mounting of the rolling element further away from the second guide (ski side surface guide) can be an eccentric include.

If you want to process a ski edge running surface in the plane of the actual ski running surface, it can be advantageous i.if you do not use the actual cutting tool at the same time SkilsufflMche edited, i.e. if, for example, the the end of the cutting edge that processes the ski edge running surface facing the actual ski running surface comes to lie where the actual ski running surface and the ski edge running surface against each other boundaries.

Guide) and runs parallel to the actual ski edge of an applied ski 10. The planes of rotation of the three guide disks 6, 6 ¹ , 6 ′ are also arranged parallel to the actual ski edge of the applied ski 10. The guide disk 6 provided at the tip of the isosceles triangle sits on the central eccentric section 14 of an eccentric 3. The eccentric section 14 of the eccentric 3 is located between the two threaded and non-eccentric end sections 13, 15 of the eccentric 3, which are also can be referred to as foot 13 and head 15 of the eccentric 3. The foot 13 of the eccentric 3 sits in a threaded hole 16 and can be screwed back and forth in this threaded hole 16.
