DE2621111A1 - Cross country ski binding converter - contains pivoted adjusting bracket with three positions for descent, ascent and cross country travel - Google Patents

Abstract

The converter makes it possible for a cross country ski binding to be used also for down hill or climbing. A vertically pivoted adjusting bracket (2) may be locked in three positions in the rear binding area. One position (A) fixes the binding (1) on the ski for downhill skiing while the cross-country position (8) frees the binding for the complete pivot range. In the climbing position (C) the bracket serves as a contact for the rear binding end at an angle of about 15 deg. above the ski, to avoid non-essential upward movement. The remaining pivot area is kept for the climbing movement of the foot.

Annex 2

Title: Changeover device for .ikitouring bindings Area of application: The invention relates to a changeover device for ski touring bindings for descent, Cross-country skiing and ascent.

Purpose: Ski touring bindings are intended for skiers to use energy-saving walking in flat and sloping terrain. The shoe should be used for the descent can be grounded like a downhill binding on the ski. The conversion is supposed to be simple and effortless.

Prior art: These requirements are met by the known Plate or rod touring bindings only partially fulfilled. (Magazine: "InterSKI" Volume 1976 No. 3 page 3d, magazine: "Bergwelt" Volume 1974 No. 3 page 66 and No. 4 on page 41).

These bindings give the foot in the cross-country / ascent position up to 90 ° vertical swiveling freedom around an axis in the area of the toe of the shoe. For the Ascent in steep terrain, it is known to use a spiral spring under the heel to reduce the idle stroke. (Journal: "Deutscher Alpenverein, Mitteilungen. Jugend am Berg "28th year, ran 1/1976 page 46) Criticism of the state of the art: The changeover from cross-country skiing / ascent to descent and vice versa is common practice Touring bindings cumbersome. For some, the shoe has to be released from the binding with other versions, levers only have to be operated by Bending over and twisting the body at the same time can be achieved. This is Tiring, especially on tours with a backpack. For walking on flat and steep slopes Terrain there is generally only one binding position "Tour". The idle stroke1 of the in the; partial ascent is to be overcome by the foot, acts with the associated kink tiring of the ankle.

(Journal: "InterSKI" year 1976 No. 3 page 26, picture) The o.a. The spiral spring is only a partial remedy as it is not suitable for difficult skiing To guide the terrain safely and only reduce the idle stroke when unloaded.

Task: The invention is based on the task of converting Plates / rods touring bindings in the three positions downhill, cross-country skiing and ascent to enable effortlessly and to switch off the idle stroke in the increase position.

Solution: This object is achieved according to the invention in that a vertically swiveling reversible handle in the rear binding area locked in 3 positions can be. senses position fixes the binding on the ski for the downhill position. The cross-country position releases the binding around the entire swivel range.

In the ascent position, the switch bar serves as a support for the rear end of the binding approx.

150 above the ski. The remaining swivel range remains for the Maintain climbing motion of the foot.

Achievable advantages: The advantages that can be achieved with the invention exist in particular that the three positions by means of a single Umstellbügelis Downhill, cross-country skiing and ascent can easily be set. the Training of the Umstellbügel allows the conversion with the ski pole from an upright position Posture. In steep terrain, there is an idle lift with safe ski guidance at the same time of the foot avoided.

The changeover device can by means of suitable adapters with can be combined with most known plates / rod touring bindings.

Description; of 2 exemplary embodiments: exemplary embodiment 1 of The invention is shown in the drawing Figs. 1-3 and will be described in more detail below described.

It becomes the three-sided view of the rear of a plate touring binding shown with a U-shaped plate (1) and resilient changeover bracket (2).

1 shows the side view. The conversion bracket (2) is in the Downhill (A), cross-country skiing (B) and ascent (G) positions shown. He's got in the bucks (3) its fulcrum. The U-shaped plate (1) is in the lowered position and shown in the rise position resting on the switch bar (2). The idle stroke is represented by the angle (alpha). The hole (4) is used for locking in the departure position (A).

Fig. 2 is the rear view. The left half of the drawing shows the position Departure (A) again.

The outwardly bent end of the Umstellbügel (2) holds the plate (1) in the hole (4).

The right half of the drawing shows the rise position (C). The changeover bracket (2) is held in place by the catch (5).

3 shows the top view. The left half of the drawing shows the position Departure (A) again.

The outwardly bent end of the Umstellbügel (2) holds the plate (1) in the hole (4).

The right half of the drawing shows the cross-country skiing position (B). The switch bar (2) with its outwardly bent end is in the notch (6) pulled out of the hole (4) and gives the plate (1) over the entire ichwenkbereich free.

Embodiment 2 is shown in the drawing Fig. 4 and is described in more detail below: Fig. 4 shows the rear view of the changeover device. The brackets (3) are attached here with the notches facing outwards. The resilient adjustment bracket (8) with its inwardly curved ends fulfills the same functions as the Deflection bracket (2) in the exemplary embodiment: 1. This arrangement enables the combination the changeover device by means of an adapter (7) to most known plates / frame touring bindings.

The left half of the drawing shows the adapter (7) in position Departure (A) fixed.

The right half of the drawing shows the rise position (C), in which the Umstellbügel (8) serves as a support for the adapter.

The cross-country skiing position (B) corresponds to that in exemplary embodiment 1 shown.

Claims (1)

Appendix 3 claim changeover device for ski touring bindings for departure. Cross-country skiing and ascent, that is not enough a vertically pivotable Umstellbügel (2; 8) in the rear binding area in three Positions (A, B, C) can be locked so that a position (A) the binding (1; 7! Fixed on the ski for the downhill position, the cross-country position (B) the binding releases around the entire swivel range and in the rising position (O) the switch bar as a support for the rear end of the binding at an angle that avoids the idle stroke (Alpha approx. 15 °) above the ski is used, with the remaining swivel range for the Climbing movement of the foot is maintained.
