Description

/ Vt »

To prevent slipping back when going up on skis, one used up to now, apart from seal skins and climbing wax, straps also strapped across the tread and special crampons that can be attached to the SH. The straps were only a primitive expedient; they slipped easily, rubbed get through and get lost. The crampons mentioned had the same disadvantages. In addition, installation was difficult in extreme cold or storm; often you had crampons when you had them needed, not at hand as they were not attached to the ski and therefore easily at home could be forgotten. Crampons firmly attached to the ski have also been suggested, which acted, for example, in the form of two spurs engaging behind the binding on both sides of the ski. During the ride . ao the parts engaging in the snow swiveled backwards like a latch and dragged in the snow after. The laterally protruding spores, however, prevented the climb and when swinging, moreover, their braking effect was due to their narrow width only very weak. A disadvantage of this device was also that the device itself Located at the top of the ski where it could easily become clogged with snow.

There are also inhibiting devices known in the form of spurs or rails in Longitudinal slots of the ski lie and are pushed out when in use. These "devices However, they have not proven successful because they slide back due to their narrow width could not prevent.

The subject matter of the invention now forms a crampon which does not have the disadvantages of the known devices mentioned, but at the same time as a guide iron for crusty snow or ice according to Art the well-known crampons can be used.

The device is expediently attached to the ski just before the binding and is in the drawings, for example, shown in one embodiment.

which is attached to the underside of the ski, is sunk and pushed out of this slot in the case of four turns and placed transversely, or if it is to be used as a crampon, is set in the slot that it is partly out of this and over the tread of the Ski protrudes. Turning the crampon into the required position and holding it in this position can be done in various ways. In the drawings, only one embodiment of the device used for this purpose is shown and described below. The device consists of a bearing part i which is fixedly attached to the top of the ski 4 and which has the two attachments 2 and 3 on its outer surface at different heights and horizontally offset by 900. In zo this lower part 1 an upper part 5 is mounted displaceably and rotatably by the spindle 6, the circular head 9 of which is provided with a corrugation for better handling. On the underside of this rotatable part 5, a shield-shaped extension 7 is attached, the lower edge of which is bent inwards at right angles and carries the recess 8 into which the extension 2 or 3 fits. At the lower end of the spindle 6, a closing body 10 of elongated, rhombic plan shape (Fig. 4) is rotatably attached to it, and the crampon or crampon 11 is attached underneath it to the spindle 6. This has the same horizontal section as the end body in the "upper part" and gradually runs down into a sharp edge. In the ski there is the slot-shaped recess 12 corresponding to the shape of the end body 10 and the crampon 11, which would accommodate both Parts is used. The rotatable part 5 is supported against the bearing part 1 by a spring 14. On the bearing part 1 as well as on the upper rotatable part 5, cylindrical +5 shells 15 and 16 made of sheet metal are attached, which slide into one another and protect the device against snow. The device is used in the following way: During the descent, the crampon 11 lies in the recess 12 so that its lower edge does not protrude into the groove 13 of the sliding surface. This position is shown in Fig. 1. If the crampon is now to come into effect, the corrugated button 9 is turned a quarter turn to the right (or left, depending on the arrangement), while pressing it down at the same time, so that the shield-like projection 7, which was first in front, sideways comes and is held by playing the approach 2 in the recess 8 in this position. This position is shown in Fig. 2. The end piece 10 then closes the recess 12 on the underside of the running surface against the ingress of snow, and the crampon 11 protrudes over the running surface, whereby it is positioned transversely to the sliding direction of the ski. If you want better ski guidance in rough or icy snow, turn knob 9 from the initial position half a turn to the right, first pushing the crampon out of the slot and turning it, and then when the pressure is released at the end of the turn partially goes back into the slot 12 again. The approach 3 of the bearing body arrives here in the recess 8 of the Schüdansatzes, _ which is now on the opposite side of the initial position. As a result, the crampon 11 is held in the position shown in Fig. 3 and now forms a guide iron, half jumping out over the tread. The device described has the particular advantage that it is firmly attached to the ski. The cumbersome and often laborious assembly is no longer necessary. When in use, a handle is sufficient to bring the iron into one or the other desired position. The device is in no way a hindrance, since there are no laterally projecting parts. The crampon itself is sunk into the ski when it is not in use; The surrounding metal sleeve prevents snow from entering. The longitudinal slot made in the ski wood to hold the crampon does not weaken the ski. The device is light, simple to manufacture and assemble, and inexpensive in price. Patent A jsi s l'Kü cn κ: 1.
