Definitions
- the invention relates to a toe piece according to the preamble of claim 1.
- the bolt is centered in the driving position by an elastic mass which surrounds the bolt in a ring and which is held in place by a ski-fixed component.
- the ring shown in FIG. 6 has a certain elastic holding function on the bolt and thereby on the sole holder, but a positive locking of the bolt and thus the sole holder is not possible in this way.
- This construction therefore has the disadvantage that a pivoting of the bolt and thus of the sole holder is possible even while driving, ie if the bolt carrying the sole holder is to be held immovably.
- the pin is held in place by control cams which are arranged on approaches of the two angle levers.
- the bolt can only be released if one of the angle levers has already been pivoted through the ski boot of the skier at a certain angle. As a result, the friction between the sole holder and the ski boot is reduced with a delay.
- the invention has for its object to eliminate the disadvantages of the known designs and to create a toe that raises the sole holder, which is locked in the driving position, at the beginning of a backward fall of the skier, thereby immediately reducing the friction between the sole holder and the sole of the shoe.
- this object is achieved according to the invention by the measure of the characteristic Part of this claim solved. If the skier falls backwards while driving, the sole holder is raised and the bolt is unlocked. If there is also a backward fall, the sole holder can immediately pivot laterally, so that a low-friction release of the shoe sole is ensured.
- the subject matter of claim 3 ensures a compact overall height of the toe piece.
- the measures specified in claim 4 enable the sole holder not only to be pivoted laterally in the event of a backward fall of the skier, but also to be raised at its rear end.
- the subject and the position of the bolt are defined in the event of a backward fall of the skier.
- Fig. 1 is a vertical longitudinal central section through the first embodiment and Fig. 2 is a partial section along the line II - II in Fig. 1.
- Fig. 2a is a detail of Fig. 2 on an enlarged scale and
- Fig. 2b is a section along the line IIb - IIb in Fig. 2a.
- Fig. 3 is a section along the line III - III in Fig. 1.
- Figs. 4 and 5 correspond to Figs. 2 and 3, however, the pivoted position of the sole holder is shown.
- Fig. 6 is a vertical longitudinal central section through the second embodiment and
- Fig. 7 is a partial section along the line VII - VII in Fig. 6 on an enlarged scale.
- 8 shows a section along the line VIII-VIII in FIG. 6.
- Fig. 9 corresponds to Fig. 7, but with the sole holder in a pivoted position.
- the toe piece shown in FIGS. 1-5 is designated 101 in its entirety. It has a housing 102 to which an approximately angular support body 103 is fastened in the vertical longitudinal center section.
- the housing 102 and the horizontal leg 103a of the support body 103 are fastened to the top 100a of a ski 100 in a known manner.
- the other leg 103b of the support body 103 extends perpendicular to the upper side 100a of the ski 100 and carries at its upper end an axis 104 which is arranged in the direction of the ski and parallel to the upper side 100a of the ski.
- An angular compensation lever 105 is mounted on this axis 104, one leg 105a of which runs horizontally and essentially parallel to the leg 103a of the support body 103.
- leg 105a of the compensating lever 105 there is a vertical bore 105c which is penetrated by a screw bolt 106, the shaft of which is designated 106b and the thread of which engages with a threaded bore in a sole holder 108.
- the head 106a of the screw bolt 106 lies on the horizontal leg 105a of the compensating lever 105 and allows the screw bolt 106 to pivot to all sides by means of a bearing in the manner of a ball joint.
- the screw bolt 106 is secured against rotation by a leg spring 119, which is supported on flats below the head 106a of the bolt bolt 106.
- the ends of which are anchored in the leg 105a of the compensating lever 105.
- Under the leg spring 119 there is a top view U-shaped insert 118 which is pushed onto the screw bolt 106 and ensures that its head 106a is supported in the leg 105 of the compensating lever 105 with play.
- a conical taper 106c adjoins the lower end region of the shaft 106b of the screw bolt 106, which tapers into a cylindrical extension 106d.
- the extension 106d carries a coaxially arranged washer 107, which is held in position by means of a rivet head 106e and which limits the displacement path of the screw bolt 106 and thus the pivoting angle of the compensating lever 105.
- An elongated hole 103c is located in an upward curvature of the horizontal leg 103a of the support body 103.
- the elongated hole 103c is provided in its central portion with a cylindrical widening 103d, which is intended to receive the cylindrical shaft 106b of the screw bolt 106.
- the boundary wall 103f of the elongated hole 103c is chamfered in its lower region (see FIGS. 2a and 2b), which makes it easier for the screw bolt 106 to swing out laterally in its raised state.
- the structure of the front jaw 101 which is known per se, is as follows:
- the leg 103a of the support body 103 carries two vertical axes 109 at a lateral distance from the vertical longitudinal center plane of the front jaw 101, on each of which angular levers 110 are mounted, one of which is a leg for lateral mounting the sole of a shoe used in the toe blocks 101, not shown.
- the other leg interacts with a slide 115 to be described in more detail.
- a trigger spring 111 which is designed as a compression spring and extends in the longitudinal direction of the front jaw 101, is accommodated in the housing 102.
- the leader tion of this release spring 111 can be adjusted by means of a sleeve 112 with an internal thread.
- the sleeve 112 is screwed onto the threaded section of a pull rod 113 which passes through the release spring 111 in the center.
- a further sleeve 114 which performs the function of a spring plate, is supported on a collar of the sleeve 112.
- the pull rod 113 At its end adjacent to the ski boot, the pull rod 113 carries the angular slider 115, as seen in the vertical longitudinal center section through the front jaw 101.
- the stepped end of the pull rod 113 is inserted and riveted into a hole in the vertical leg 115b of the slider 115.
- a pull toward the ski tip is exerted by the release spring 111 via the pull rod 113 on the slide 115.
- the slider 115 acts on each of the two side angle levers 110 and the compensating lever 105.
- the leg 115a of the slider 115 which runs parallel to the top 100a of the ski 100 and is directed towards the ski tip, has a scale 116 with a slot 117, in which a mark 114a fastened to the sleeve 114 is displaceably guided.
- the sole holder 108 is first raised. At the same time, however, the compensating lever 105 is also pivoted and the screw bolt 106 is moved upward until the washer 107 comes to rest on the underside of the bulge 103e of the leg 103a of the support body 103. Now the cylindrical shaft 106b of the bolt 106 is released from the clasping by the cylindrical widening 103d, and The extension 106d of the screw bolt 106 can - if there is a backward turning fall - move to one end of the elongated hole 103c.
- the release spring 111 guides the sole holder 108 back into its starting position via the compensating lever 105, the screw bolt 106 being pressed downward. This has the consequence that the cylindrical shaft 106b gets into the cylindrical widening 103d of the elongated hole 103c, which causes the screw bolt 106 to be centered. The sole holder 108 is then again in its position approximately parallel to the upper side 100a of the ski 100.
- FIGS. 6-9 The embodiment of a toe 201 shown in FIGS. 6-9 is similar to that described first. For this reason, the individual elements of the front jaw 201, which correspond to the elements of the first embodiment and are therefore not described separately, are each provided with a reference number that is 100 higher.
- the elongated hole 220c in the front jaw 201 which is approximately banana-shaped or kidney-shaped in plan view, the concave curvature facing the ski boot, is not recessed in the leg 203a of the support body 203, but in the central height region of a control block 220, which is arranged immovably in a recess of the leg 203a, and which is held by the housing 202 in the assembled state of the toe 201.
- a conical depression 220b in the control block 220 to which a cylindrical opening 220a and then an exemption 220d are connected.
- a cavity 220f which has a ceiling 220e, is cut out in the control block 220.
- the structure of the screw bolt 206 is as follows in the present exemplary embodiment. Below the threaded section is a cylindrical shaft section 206b, which merges into a cylindrical end section 206d via a step. A sleeve 221, which is described in more detail below, is mounted on the latter.
- the screw bolt 206 also carries a coaxial washer 207 at its lower end, which is held in place by means of a rivet head 206e. Furthermore, the ceiling 220e of the cavity 220 f is curved downward in a convex arc (see FIG. 8). This results in a defined position for the pivoted screw bolt 206 and thus also for the sole holder 208.
- the sole holder 208 is first raised.
- the compensating lever 205 is also pivoted, and the screw bolt 206 and the sleeve 221 are moved upwards until the washer 207 comes to bear against the ceiling 220e of the cavity 220f of the control block 220.
- the cylindrical part 221a of the sleeve 221 is released from the clasping through the cylindrical opening 220a, and the cylindrical end portion 221c of the sleeve 221 can - if there is a backward turning fall - move towards one of the two ends of the elongated hole 220c, which causes the sole holder 208 to be inclined about the longitudinal axis of the ski has the consequence.
- the sole holder 208 is also pivoted somewhat about an ideal transverse axis Y - Y. This makes it even easier for the skier to get out of the toe 201 with the ski boot in the event of a backward fall.
- the release spring 211 returns the sole holder 208 to its starting position via the compensating lever 205, the screw bolt 206 and also the sleeve 221 being pressed downward.
- the opening angle of the conical section 221b of the sleeve 221 corresponds to the opening angle of the conical depression 220b in the control block 220.
- the invention is not tied to the exemplary embodiments shown in the drawing and described above. Rather, various modifications thereof are possible without leaving the scope of the invention.
- the bolt can also be smooth, the sole holder being automatically adjustable along the bolt against the force of a compression spring.
- the banana or kidney-shaped design of the elongated hole can also be used in the first embodiment.
