Definitions
- the invention relates to a toe piece according to the preamble of claim 1.
- Such a front jaw is described for example in EP-A2-0408 855.
- the trigger plate is flat in the vertical direction.
- the bearing part has a rearward projection in its lower end section, which is used to abut the release plate.
- the invention has set itself the goal of designing a front jaw of the type mentioned at the outset in such a way that the triggering behavior of the ski binding is linear or slightly progressive.
- the release plate has a control surface in its lower section on its side facing the bearing part and that the control surface - viewed in longitudinal section - runs upwards and forwards, in cooperation with the rearward projection of the bearing part a linear or slightly progressive release behavior of the ski binding achieves a favorable course of the force action line.
- control surface could be designed as a flat surface to be increased towards the front, it has proven to be advantageous to make the control surface of the release plate continuously arc-shaped in accordance with the features of claim 2.
- the configuration according to the characterizing part of claim 3 enables a compact structure of the ski binding and an improved diagonal release behavior.
- FIG. 1 shows a longitudinal section through the toe piece according to the invention in the position of the ski binding ready for entry
- FIG. 2 shows a detail of the toe piece cut along the line II-II of FIG. 1
- FIG. 3 shows an illustration similar to FIG .2 with laterally pivoted bearing part
- Fig.5 is a representation as Fig.4, wherein the sole holder is pivoted further upwards
- Figures 4a and 5a each show details of Figures 4 and 5 on a larger scale.
- Fig.l the toe 1 according to the invention is shown in the position ready for entry. It has a housing 2, which is fastened to a ski 50 by means of only indicated screws 51.
- a release spring 40 is accommodated in the housing 2, the pretensioning of which can be adjusted in a known manner by an adjusting device 43.
- the release spring 40 is arranged between a spring plate 41 and, with the interposition of a bearing bush 42, a vertically running rear transverse wall 3 of the housing 2.
- the release spring 40 is penetrated in the axial direction by a pull rod 10, one end 11 of which cooperates with the adjusting device 43 and the other end 12 of which is connected to a substantially vertically extending release plate 13.
- the release plate 13 has at its lower end 14 a control surface 15 directed towards the ski tip and to be described in more detail later, and a stop 16 pointing towards the rear, ie in the direction of a shoe to be inserted.
- first curve 5 At the top of the vertically running rear transverse wall 3 of the housing 2 there is a first curve 5 and a section 6 running horizontally to the rear.
- the bearing part 20 is from , seen in the rear frame-shaped, ie provided for the pull rod 10 with a through opening 21, and - seen in side view - has approximately the shape of a C.
- the vertically extending portion of the C is formed by the support wall 22 and has a front support surface 23 and a rear support surface 24.
- the front support surface 23 of the bearing part 20 has two sections adjoining one another in the vertical direction, the lower section 25, viewed in the ready-for-entry position of the front jaw 2, abutting on the rear side 4 of the rear transverse wall 3 of the housing 2.
- the upper section 26 forms an obtuse angle ⁇ with the lower section 25.
- the bearing part 20 has a tilting edge 27.
- the upper leg 32 of the bearing part 20 is provided in the region of the longitudinal central axis with a surface 28 which is inclined towards the rear and downwards.
- the transition between the upper section 26 of the front support surface 23 and the surface 28 which is inclined backwards and downwards is designed as a further curve 29.
- the bearing part 20 is fork-shaped in the area of the longitudinal central axis in plan view and has a recess 30 which is open towards the front and a projection 31 which is to be described in more detail to the rear.
- a corresponding wedge-like projection 7 of the housing 2 is assigned to the recess 30.
- a travel limiter 8 facing the stop 16 of the release plate 13 is also arranged on the housing 2.
- the control surface 15 is curved forward (towards the tip of the ski) and continuously curved.
- the Horizontal section shows that the control surface 15 essentially consists of a first section 15a, which runs approximately transversely to the longitudinal axis of the ski, a second section 15b adjoining it, curved backwards, and an adjoining one, approximately transversely to There is a third longitudinal section 15c of the ski, an adjoining forward-curved section 15d and an adjoining fifth section 15e again running approximately transversely to the longitudinal axis of the ski.
- the rearward projection 31 of the bearing part 20 is designed to match the control surface 15 and likewise has a rearwardly curved first section 31a, followed by a second section 31b which runs approximately transversely to the longitudinal axis of the ski, and then a third section which is curved forward 31c.
- FIGS. 4 and 5 show how the bearing part 20 and the angle lever 35 are pivoted when there is an increased force directed upwards, for example in the event of a backward fall or backward turn.
- the bearing part 20 is pivoted about the tilting edge 27 against the force of the release spring 40.
- the release plate 13 detaches itself from the shorter lever arms 36 of the angle lever 35. This initially enables the angle lever 35 to be pivoted almost without force for sideways release.
- the spring 40 acts on the release plate 13 with the lower end 14 of the extension 31 in the closing direction of the toe 1.
- the extension 31 and the control surface 15 touch each other depending on the degree of pivoting at different points or lines.
- FIG. 3 the position of the extension 31 relative to the control surface 15 is shown in a simplified manner in the event of a backward lintel.
- the extension 31 touches with his about Section 31b running transversely to the longitudinal axis of the ski, the first section 15a of the control surface 15.

Abstract
Une mâchoire antérieure (1) comprend un boîtier (2) qui contient un ressort de déclenchement (40) qui agit sur une barre de traction (10) qui le traverse et qui, à son tour, agit par l'intermédiaire d'une plaque de déclenchement (13) sur les bras plus courts (36) de deux leviers coudés (35) pivotant sur une pièce de support (20) autour d'axes verticaux (34), alors que les bras plus longs des leviers forment des organes de retenue (37), de la semelle. La pièce de support (20) est pourvue d'une ouverture traversante (21) pour la barre de traction (10) et comprend sur sa section terminale inférieure une protubérance (31) orientée vers l'arrière sur laquelle s'appuie la plaque de déclenchement (13). La plaque de déclenchement (13) comprend dans sa section inférieure (14), sur sa face tournée vers la pièce de support (20), une surface de commande (15) qui vue dans sa section longitudinale s'étend vers le haut et vers l'avant. La protubérance (31) de la pièce de support (20) tournée vers l'arrière s'appuie au moins ponctuellement sur la surface de commande (15) lorsqu'une force orientée vers le haut s'exerce sur l'organe (37) de retenue de la semelle.An anterior jaw (1) comprises a housing (2) which contains a trigger spring (40) which acts on a drawbar (10) which passes through it and which, in turn, acts via a plate trigger (13) on the shorter arms (36) of two bent levers (35) pivoting on a support piece (20) around vertical axes (34), while the longer arms of the levers form organs of retainer (37), of the sole. The support piece (20) is provided with a through opening (21) for the drawbar (10) and comprises on its lower end section a protrusion (31) oriented towards the rear on which the support plate rests. trigger (13). The trigger plate (13) comprises in its lower section (14), on its face facing the support piece (20), a control surface (15) which, seen in its longitudinal section, extends upwards and towards the front. The protrusion (31) of the rear-facing support piece (20) bears at least occasionally on the control surface (15) when an upwardly directed force is exerted on the member (37) sole retention.
