DESCRIPTION
FIG. 1 is an oblique view from the front and from top of the entire ski binding. The principal components thereof are a heel part 1, a pair of connecting strips 2, and a front part 3. Together they constitute a unit which is exchangeable as a whole and is held in a selectable position by detent means 4 fastening it to take-up rails 5 which are firmly mounted on the ski 17 by screws 22. The heel and front parts 1 and 3 of the ski binding are arrested by fastening means 7 in correspondence with the size of the corresponding ski boot 20 (FIG. 2 et seq.) on the connecting strips 2.
The front part 3 can be opened by introducing the tip of a ski pole 19 in a pan 6. Fine adjustment to correspond to different ski boot sizes is accomplished by a longitudinal set screw 8 arranged so as to be readily accessible in the front portion of front part 3. A vertical set screw 9 permits the required height to be adjusted in accordance with ski boot soles of varying thicknesses.
A pair of vertical deflector rolls 14 each is supported at the heel and front parts 1 and 3. In per se known manner they permit horizontal release of the ski boot 20 whose front and rear sole edges they support. Other than that, the sole of the ski boot 20 (FIGS. 2, 4, et seq.) merely rests on mounts 13. As there is room between the connecting strips 2 to receive snow or dirt which may adhere to the sole of the boot, the release characteristics are not changed by any pressing or additional friction. The mounts 13 include rollers 18 at their bottoms for rolling movement between the connecting strips 2.
At the upper side of the heel part 1 there is an indicator including a scale 10 for the skier's own weight and a scale 11 for the contact pressure at a given length of the ski boot 20 as well as a display 12 for electrical functions by which the skier can verify the proper functioning of his ski binding at any time. All of this permits better adaptation of the ski binding to the respective skills of the skier or to external circumstances.
FIGS. 2 and 2a are a side elevation and top plan view, respectively, showing the heel part 1, the front part 3, and the releasable detent means 4 at the front part 3. FIG. 2b is the corresponding top plan view without the heel part 1 and with the front part 3 broken away in part. As shown in FIGS. 2a and 2b, the connecting strips 2 are formed with locking apertures 16 and interconnected at their ends by webs so that they can be slipped as a unit into the take-up rails 5. The fastening means 7 of the heel part 1 and of the front part 3 can be latched in the locking apertures 16.
The front part 3 has a socket which is firmly mounted on a base plate 23 by rivets 21. The fastening means 7 of the front part 3 are disposed on the base plate 23. The connecting strips 2 have a common front end 24 of the type of a leaf spring which is bent upwardly, as seen in FIG. 3, and carries the detent means 4. The take-up rail 5 in the region of the front part 3 includes rack-like notch arrangements 15 to be engaged by the detent means 4 below the front part 3.
As shown in FIG. 2b, the fastening means 7 of the heel part 1 and of the front part 3 are firmly caught in the locking apertures 16 of the connecting strips 2. Hereby the ski binding is set for a certain sole length of the ski boot 20. The entire ski binding is secured by the detent means 4 being caught in the notch arrangements 15 of the take-up rail 5 in the selected position on the ski 17, such as for downhill or for slalom skiing.
As shown in FIGS. 3a and 4a, the front part 3 includes a housing 25 which is tiltable about a pivot axis 40 with respect to the base plate 23, the pivot axis extending at right angles to the longitudinal direction of the take-up rail 5 parallel to the plane of the ski. FIGS. 4, 4a, and 4b illustrate a known manner in which to secure the housing 25 of the front part 3 to the base plate 23 thereof by means of a toggle lever 26 which is pivotable from the step-in position shown in FIG. 4a into a stretched out position shown in FIG. 4 by a person stepping w
