Definitions

  • the present invention relates to a ski binding with shear fasteners, which is pivotally attached to the ski pivotably about at least one transverse axis.
  • ski bindings are subdivided into piste bindings, which are used only for downhill skiing and downhill skiing, and touring bindings, which are also used for walking on skis, in particular for ascending with the help of climbing skins attached to the skis. While the former only have to ensure a reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must be brought to ascend additionally from the downhill to a climbing position of the binding, in which the ski boot usually only in the ski boot tip about a transverse axis is pivotally mounted on the ski and in the heel area of the ski can be lifted to allow for walking a joint movement between the ski boot and ski.
  • ski touring skiers are no longer prepared to forego the much greater grip and thereby better skiing on the downhill, which are accessible with ski touring boots made of plastic.
  • Such a touring binding which in particular also meets all the safety requirements of modern piste bindings, is described in WO 96/23559 (Fritschi). Ski bindings of this type are typically pivotable in the ascent position about a horizontal transverse axis in the area of the toe.
  • CH-659 397 (Flückiger) describes a ski binding with a walking attachment which in a first phase of the joint movement allows a pivoting movement about a transverse axis in the footpad area and in a second phase a pivotal movement about a transverse axis in the toe tip area.
  • the shoe is thus connected via a double joint connection with two different pivot axes with the ski.
  • this walking accessory allows a certain approximation to a natural movement
  • it has the disadvantage that the transition of the joint movement from a pivoting movement about the first transverse axis to a pivotal movement about the second transverse axis occurs abruptly, which causes a jerky change of the movement for the skier
  • the result is a stroke on the tibia and / or heel at each step.
  • the design tie height and consequent height of shoe position over the ski is considerable.
  • the walking gear for departure must be removed from the binding and carried separately.
  • WO 87/01296 shows a binding in which the joint between the binding plate and the ski lies in front of the toe.
  • a spacer between ski and binding plate is placed under the ball of the foot, so that a tilting movement is possible around a point, which is set back relative to the tip of the foot and practically under the ball of the foot lies.
  • the spacer is a panel substantially vertical to the ski surface which is part of a collapsible mechanism so that it can be stowed flat during descent under the binding panel.
  • the binding plate is connected at the front end via a double joint with the ski.
  • the spacer is attached to the binding plate and forms a kind of rocker with pointing down tip on which a roll is mounted.
  • the roller rolls on the flat ski upper side and moves back and forth as it moves in accordance with the tilting movement of the binding plate.
  • the connector has stoppers that define the maximum top pivot position of the connector. From the ski-parallel position, the connecting piece can therefore not be pivoted further upward than the stoppers permit. In this way, the stoppers ensure that the binding plate in the ascent position does not go beyond the "zero position" (ski-parallel position) into a "negative" inclination position.
  • the object of the present invention is to provide a ski binding by which the disadvantages of the known ski bindings are overcome.
  • the ski binding according to the invention has means for attaching a shoe to the binding, which are hingedly attached to the ski pivotably about at least one transverse axis.
  • the ski binding according to the invention has a cam body which controls the joint movement between the shoe fastening means and the ski and has at least one an area in the longitudinal direction of the convex curved surface.
  • the joint between shoe attachment means and ski must of course have more than one (rotational) degree of freedom, since a rotary joint or swivel joint with exactly one rotational degree of freedom, as is usual in known touring bindings , forces a circular motion whose orbit can no longer be controlled additionally.
  • a joint which, on the one hand, allows the shoe fastening means to be pivotably attached to the ski about a transverse axis and, on the other hand, has more than one (rotational) degree of freedom, can e.g. on a double joint with two swivel axles, a rotary-swivel joint, a curve joint u.a. based.
  • pivot movement is used below for a pure rotary or pivotal movement about a fixed pivot axis, while the articulated relative movement between the ski on the one hand and the shoe or shoe fastening means on the other hand is generally referred to as "joint movement " referred to as.
  • the inventive cam body controls the joint movement by means of a rolling process between the convexly curved surface and a mating surface.
  • the rolling process between the convexly curved surface, which defines a rolling or rolling-off curve in the longitudinal direction of the ski, and the mating surface can consist of a pure, sliding-free rolling or a rolling combined with sliding.
  • rolling and the terms derived therefrom are used both for a smooth rolling and a rolling combined rolling.
  • ski binding in the following is not mistaken to mean that a ski binding can be mounted exclusively on skis.
  • binding refers rather to a binding which, in addition to attachment to piste and touring skis, can also be attached to all other types of skis, snowboards, big-foots, snowshoes, roller skis, skate skates and similar devices which provide a flexible connection between a shoe and a ski require the device.
  • the inventive device ensures an ergonomic, smooth movement when climbing with skis.
  • a further advantage results from the use of a tour binding according to the invention in conjunction with a climbing aid customary for touring bindings. Since the binding according to the invention already provides a substantial facilitation of ascending, in particular on steep terrain, the climbing aid used in conjunction with the binding according to the invention must support the heel of the shoe less highly in comparison with climbing aids with known touring bindings, in order to achieve the same degree of relief during the ascent cause. Thus, smaller and therefore lighter climbing aids can be used in connection with the binding according to the invention than with conventional touring bindings.
  • the cam body when the ski boot is lowered, is arranged in an area between the ski boot and the ski, viewed in the ski longitudinal direction, in front of the shoe center.
  • the cam is configured and arranged so that at least in one phase of the articulation movement for ascending the cam is rolled so that the distance between the shoe heel and the support line of the cam increases with increasing lift the shoe heel.
  • the cam body is provided for the purpose of longitudinal guidance of the cam during articulation with at least two stepwise arranged surfaces.
  • the stepped surfaces may be formed to cooperate with correspondingly shaped step-shaped surfaces on the ski or on binding parts attached to the ski.
  • the cam body is arranged on the shoe fastening means and / or on other fastening parts attached to the shoe such that when the shoe is lowered, the convexly curved surface lies on the underside of the cam body which is opposite the ski upper side.
  • a rib transverse to the ski longitudinal direction is arranged under the cam body that at least in a phase of joint movement of the cam body is rolled on the rib, in which phase the distance between the shoe heel and the bearing line of the cam remains substantially constant as the heel of the shoe increases.
  • the cam body is designed as an integral part of the shoe fastening means.
  • the shoe attachment means comprise a support on which the ski boot is fastened, wherein the cam body is designed as a front part of this carrier.
  • the inventive binding further comprises a double joint-like device, wherein the shoe fastening means are pivotable about a first transverse axis pivotable on an intermediate member, which is articulated pivotably about a second transverse axis on the ski.
  • the first transverse axis is formed as a pivotal connection between the intermediate member and the cam body.
  • a further advantageous embodiment of the invention is characterized by a spring which acts between the intermediate member and the shoe fastening means and which is designed and arranged such that it counteracts a pivoting movement of the shoe fastening means in the direction of increasing the heel of the shoe about the first transverse axis.
  • a spring acting between the intermediate member and the ski which spring is designed and arranged in such a way that that it counteracts a pivoting movement of the intermediate member in the direction of an increasing angle between the ski and the intermediate member about the second transverse axis.
  • the two springs are designed and arranged such that a greater torque is exerted with respect to the second transverse axis by the spring acting between the intermediate member and the ski than by the spring acting between the intermediate member and the shoe fastening means with respect to the first transverse axis.
  • Figures 1 and 2 represent a A ski binding with a cam 280.
  • the example shown in Figures 1 and 2 has a double-jointed device.
  • the carrier 260 with a front sole clamp 270 is pivoted about a first transverse axis 230 to an intermediate member 240, which is hinged about a second transverse axis 220 pivotally mounted on a mounting part 250.
  • the intermediate member 240 in this example consists of a center plate which is in the lowered position of the binding substantially parallel to the ski top side, and two side parts, which are provided with holes for the pivot axes 220 and 230.
  • the fastening part 250 can be fastened to the ski (not shown) by means of screws 252, 254.
  • the plate-shaped fastening part 250 is behind the bearing for the second transverse axis 220, viewed in the longitudinal direction of the rear, extended.
  • the top of this extension forms the mating surface 251, on which the convex curved surface 281 of the cam body 280 mentioned below is rolled.
  • a rib 290 extending transversely to the longitudinal direction of the ski is formed on the fastening part 250.
  • a cam 280 is formed in its foremost region, which is formed as an integral part of the carrier 260.
  • the cam body has on its underside a convex curved in the longitudinal direction surface 281, which defines a rolling / rolling curve, wherein the surface is formed transversely to the ski longitudinal direction straight.
  • the cam body 280 (and thus the carrier 260) is pivoted about the position of the toe of the ski boot fixed on the shoe wearer 260, pivotally about the transverse axis 230 on the intermediate member 240.
  • the binding components are arranged such that the course of the joint movement between the shoe carrier 260 and the shoe and the ski during lifting of the shoe heel takes place in three phases.
  • the binding is shown in the lowered shoe heel position, at the beginning of the first phase.
  • the cam 280 is rolled on the rib 290 with the distance between the shoe heel and the support line 285 of the cam 280 (contact line between the convex surface 281 and the counter surface 251) remaining substantially constant.
  • the skier exerts the greatest forces on the shoe and the binding on the weighted ski, so a small distance between the shoe heel and the bearing surface 285 of the cam and thus a small articulated lever is advantageous.
  • the cam body 280 In the second binding movement phase (roll-off phase), the cam body 280, with its convexly curved surface 281, is rolled over on the counter surface 251 on further lifting of the shoe heel. Due to the articulated mounting of the cam 280 on the intermediate member 240, the rolling does not consist of a pure, slippery rolling movement, but of a combination of rolling / rolling and sliding. By this rolling movement, the distance between the shoe heel and the support line 285 of the cam 280 in the second phase increases continuously by the support line 285 of the cam 280 moves continuously on the counter surface 251 forward. In the second phase illustrated in FIG. 1.b, the forces to be exerted on the ski by the skier continuously decrease. The second phase is completed with the achievement of a first stop (not shown) for limiting the pivoting movement about the first transverse axis 230. The first stop blocks a continuation of the pivoting movement about the transverse axis 230.
  • the first transverse axis 230 is blocked by the first stop, whereby the joint movement only consists of a pivoting movement the second transverse axis 220 exists.
  • the touring skier shifts his weight to the other ski and begins to follow the skis that are essentially resting on the snow until then.
  • FIGS. 3.a to 3.f show a first preferred embodiment of the invention which is similar to the example illustrated in FIGS. 1 and 2 and described above.
  • the intermediate member 340 is made substantially shorter than the intermediate member 240 described above, and the transverse axis 330 is disposed in the region below the toe on the formed as an integral part of the shoe wearer 360 cam 380.
  • the effect of the cam body 380 for the first phase of the movement sequence approximates a fulcrum in the footpad area and thus an ergonomic sequence of movements.
  • a second stop provided so that a pivoting in the direction of lowering the heel on the joint position when lowered shoe is made impossible. This prevents that the double joint in the downhill position of the binding of an upward force of the toe, as it may arise, for example when skiing with reserve, undesirably yielding.
  • the blocking of the pivoting movement about the first transverse axis 330 by the second stop may also be useful in the ascent position of the binding, for example when carrying out step steps or hairpin bends in ascent.
  • a projection is formed on the cam body 380, which pushes in the binding position with lowered shoe heel with its front side 382 against a correspondingly shaped rear side 342 of the intermediate member 340.
  • Figures 3.c-3.f the embodiment of the invention shown in Figure 3.a is shown in various joint positions - i. with raised to different heights shoe heel - shown.
  • Figure 3.c the binding in the position mitabgesenkter shoe heel, at the beginning of the movement sequence for a rise step, is shown.
  • the intermediate member 340 is raised at the end with the first transverse axis 330 upwards, and its rear side 342 abuts against the correspondingly shaped front side 382 on a cam formed on the cam 380 and thereby forms a stop for limiting the pivoting movement about the first transverse axis 330, a Pivoting in the direction of lowering the heel over the joint position with the shoe lowered - or a lifting of the ski boot in the area of the toe - is made impossible.
  • the support line 385 of the cam body 380 moves on the mounting member 350 continuously forward, at the same time the intermediate member 340 is first lowered in the region of its first transverse axis 330 and later raised again.
  • this embodiment of the invention provides a round, ergonomic movement.
  • the transverse rib may be formed on the cam body itself instead of on the mating surface opposite the cam body. without significantly changing the function and purpose of the cross rib.
