Definitions

  • the invention relates to a cross-country ski binding for cross-country shoes with a front sole extension, about a transverse to the longitudinal axis of the cross-country ski or the cross-country ski axis pivoting locking member, which in the closed position can be pressed against the top of the front sole extension facing away from the ski, wherein a plate-shaped profile body is provided on the ski surface, which can be positively brought into operative connection with the sole of the shoe.
  • cross-country bindings of this type it is known to insert the sole extension of the cross-country shoe into a pocket and to secure the pocket representing the binding part attached to the ski against displacement in this pocket.
  • the invention now aims to provide a construction of the type mentioned in the introduction, in which the locking member enables the shoe to be securely anchored in the binding even at a low closing pressure, with precise guidance and the possibility of a safety release being provided.
  • the invention consists essentially in the fact that the plate-shaped profile body has at least two edges offset in the longitudinal direction of the ski and extending transversely to the longitudinal axis of the ski, which cooperate with surfaces of the sole extension which are essentially normal to the sole, and that the sole of the cross-country shoe has the plate-shaped profile body in the adjoining position laterally encompassing areas which have grooves or grooves running transversely to the longitudinal axis of the running shoe.
  • a profile body on the ski surface is positively overlapped by the underside of the sole extension facing the ski, the required guidance on the ski can be ensured without impairing the flexibility of the sole or the sole extension.
  • the lock relative to the plate makes it possible to provide the plate with a safety release function and in this way realize a number of additional features, such as, for example, preventing unintentional opening and the operation of the lock to simplify the link.
  • the design according to the invention in which the areas of the sole which encompass the plate-shaped profile body laterally and have grooves or grooves running transversely to the longitudinal axis of the cross-country shoe, enables the shoe to be fixed without affecting the elastic properties and the kinematics of the rolling process of a foot on the surface of the ski. Despite the lateral overlap, the elasticity of the sole is retained.
  • the design is such that the locking member is pivotally mounted on a bracket on an actuating part pointing away from the toe of the shoe and eccentrically to the pressing surface facing the top of the sole extension, and that the bracket is attached to the ski about an axis parallel to the pivot axis of the locking member or the plate-shaped profile part is articulated.
  • Such a design is particularly advantageous in connection with the stop facing the profile body, since the actuating member of the locking member can protrude beyond the front edge of the sole extension and can be kept at a distance from the ski surface. In this way, pressing forces and a secure locking can be achieved with little effort.
  • the bracket in the area between the articulation axis of the locking member and the articulation axis on the ski is advantageously curved or angled and resilient.
  • the bracket is preferably under the action of an elastic restoring force in one of the upper surface of the ski lifted position pivoted This can be achieved in a simple manner in that the bracket is angled or cranked in the region of its pivot axis and, when it is pivoted, is pressed against an elastically compressible or resilient part.
  • the rest position is preferably the position in which the bracket is essentially normal to the ski surface, so that a particularly easy entry is made possible.
  • the pressing surface of the locking member advantageously has a groove or rib which is parallel to the pivot axis thereof and which, in the closed position of the locking member, interacts with a rib or groove on the top of the sole extension.
  • the articulation of the locking member on the bracket can also be advantageously carried out in such a way that the locking member is resiliently mounted on the pivotable bracket and is held in a predetermined pivoting position relative to the bracket by a resilient restoring force Restoring force is less than the closing force holding the closing element in the closed position.
  • the design according to the invention is such that the plate-shaped profile body is pivotally attached to the ski surface, the plate-shaped profile body preferably being held or locked resiliently in its position on the ski and being pivotably mounted against the force of a spring.
  • the pivotability can be designed so that the plate-shaped profile body together with the shoe near the front edge of the shoe is pivotally articulated about an axis crossing the longitudinal axis of the ski, essentially parallel to the surface, whereby the running comfort can be increased.
  • the swiveling can also be designed around an axis oriented essentially normal to the ski surface, so that by lateral. Swiveling the plate-shaped profile body either an immediate release of the shoe or a release of the plate-shaped profile body is possible.
  • the spring lock is used, as is known per se in alpine bindings.
  • a particularly safe triggering in the event of a fall can be achieved in that the rear end of the plate-shaped profile body facing away from the sole extension of the shoe is supported on a ski-fixed abutment and is pivotably fixed about this bearing point on the abutment.
  • Such a design has the advantage that a safety release is possible even in the event of falls to the rear, since no part of the plate-shaped profile body protrudes rearward in the longitudinal direction of the ski beyond the abutment.
  • a pivoting in the vertical direction can be done around the counter Bearings are made at the rear end of the plate-shaped profile body.
  • the training is made in a particularly simple manner in such a way that the ski-resistant abutment has a head that overlaps the top of the plate-shaped profile part and that the clear width between the areas of the sole of the shoe encompassing the plate-shaped profile part is at least equal to the transverse dimension in every pivoting position of the plate-shaped profile part of the head is.
  • the locking member is articulated on the plate-shaped profile body, in which case operability is facilitated in that the locking member carries a stop which interacts with a counter-stop on the plate-shaped profile body.
  • the training is made in a simple manner so that the locking member bears a stop facing the ski surface, which in the closed position interacts with a side of the wall facing the shoe, a rib or a groove of the plate-shaped profile part as a counter-stop, the sole extension preferably being one Has recess or opening for the stop provided on the locking member.
  • a further improvement in securing against displacement of the shoe in the longitudinal direction of the ski and the kinematics of the rolling process can be achieved in that the profile body rises at its front end relative to the plane of the ski surface and in its end region parallel to the ski surface or descending to it in an essential passes normally to the top of the ski, which forms the counter-stop for the stop provided on the locking member.
  • the profile body can be overlapped laterally by extensions on the sole of the shoe.
  • the design according to the invention also allows the profile body to be pivotably attached to the ski surface, the profile body preferably being held resiliently in its pivot position lying against the ski surface.
  • the profile body is preferably concave on its outer surface facing the sole, wherein a certain amount of suspension can be achieved by the profile body being hook-shaped in longitudinal section in its rear end region and with its downward end on rests on the surface of the ski.
  • This resilient support of the boot on the ski is particularly favorable in the case of highly flexible soles, since it significantly increases the comfort of the binding.
  • a further increase in comfort when running can also be achieved in that the profile body has tabs projecting laterally over the ski, the axial length of which extends at least into the ball area of the boot, thereby increasing the repelling area for the ball.

  • FIG. 18 a top view in the direction of the arrow XVIIT: the Fig. 17.
  • a profile body 1 is fixed to the top of a ski 2.
  • a bracket 3 is pivotally articulated, which carries a pivotable locking member 4.
  • the actuating member 5 of the locking member 4 has a downward-facing wall 6, which in the closed position shown in FIG. 1 interacts with an upward-facing wall 7 of the profile body as a counterstop and is thereby held at a distance from the top 8 of the ski.
  • the cross-country ski boot 9 has a sole extension 10, in which the wall 6 forming the stop is immersed in the closed position.
  • the closing member 4 engages a projection 11 of the sole extension 10 and holds the sole extension 10 in engagement with the profile body 1.
  • the sole 12 has lateral projections 13 which engage around the profile body 1.
  • the profile body 1 is supported by a hook-shaped angled end 14 on the surface 8 of the ski and is therefore elastically resiliently mounted, at least in its partial area corresponding to the ball area.
  • the outer surface 15 of the profile body facing the sole 12 of the shoe is concavely curved.
  • a profile body 16 can be seen which, in addition to the upward-facing wall 7 which forms the counterstop and which is already shown in FIG is made possible.
  • the profile body 16 can be fastened by means of screws through the holes 20 provided for this purpose.
  • the profile body 16 has at its front end region an opening 21 for the pivot axis 22 of a bracket for the locking member, as can be clearly seen in FIG. 3.
  • the opening 21 has in the interior of the profile body an enlarged cavity 23 for pivoting a cranked part of a bracket 24, as shown in FIG. 4.
  • FIG. 3 also shows a recess 25 running in the longitudinal direction 17, into which an elastic body is inserted can, which exerts a restoring force when pivoting a cranked bracket 24.
  • this restoring force is not exerted by a resilient element 26 located below the cranked partial area in a recess 25 according to FIG. 2, but by a resilient element 27 corresponding to the embodiment according to FIG. 5.
  • This resilient element 27 shown in FIG. 5 has punched-out and swung-up spring tabs 28 which, due to the cranked configuration of the bracket 24, press the cranked partial area 26 into a predetermined position in which the bracket 24 stands essentially normally on the ski surface.
  • Fig. 4 the profile body is again designated 1 and, like the sole extension 10, is shown in cross section.
  • the sole extension 10 has a central groove 29 running in the longitudinal direction of the shoe, into which the wall 6 of the actuating member 5 of the locking member 4 forming the stop is immersed in the closed position. Through this wall 6, a high degree of lateral support is achieved in connection with the form fit in the groove 29 and the form fit of the part 10 on the profile body 1 and by the form fit in the profile body 10 or 16, which results from the interaction of corresponding parts of the sole with the walls 7, 18 and 19 results in securing against displacement in the longitudinal direction is ensured.
  • FIG. 6 again shows the locking member 4, the actuating member 5 of which is angled relative to the pressing surface 31 arranged eccentrically to the pivot axis 30 of this locking member.
  • This angled part of the actuator 5 is stiffened by the wall 6, which in turn represents the stop which cooperates with the counter-stop on the profile body in the closed position.
  • Such a locking member 4 can be pivoted to the free ends 32 of a bracket 33, this bracket 33 again having a cranked portion 26, via which the resilient return to a predetermined starting position can be achieved.
  • the bracket 33 is curved in the region between its articulation axis 22 on the profile body or on the ski and the articulation axis 30 of the locking member 4, as a result of which a certain spring effect with respect to the contact pressure is achieved.
  • the locking member 4 can likewise be deformed, with elastic pivoting of these ends 32, into a position aligned with the articulation axis 30, as a result of which an elastic restoring force is achieved in the position shown in FIG. 9 which a locking member 34 is hinged to the ends 32 of a bracket 33.
  • a rest position of the locking member 34 is assumed, in which the actuating member and the locking member is held substantially flush with the plane of the bracket 33, whereby the Entry into the free space 36 is facilitated.
  • a profile body 37 is provided which essentially corresponds to the front end region of the profile body 16.
  • This profile body 37 is fixed by a screw 38 on a spring leaf 39, this spring leaf 39 being fixed at a distance from the profile body 37 on the surface of the ski by a separate holder 40.
  • the Holder 40 consists of a fitting part 41 fixed to the ski and a jaw 42 which can be braced against this fitting part with the interposition of the spring 39, a screw 43 being provided for the bracing.
  • the profile part 37 can be pivoted away from the surface of the ski together with the spring 39 and the ease of pivoting can be adjusted by shifting the clamping length of the spring leaf 39, as can be seen in FIG. 11. 11, an elongated hole is provided in the jaws 42, in which the fastening screw 43 can be fixed in different positions, which results in a more or less easy pivotability of the profile part 37.
  • the profile body 44 has the essential features of the configuration of the profile member 1 or 16, and parts that remain the same are again identified by the same reference numerals.
  • a further recess 45 is provided, which engages around a pivot axis 46.
  • the pivot axis 46 is fixed to a separate fitting part 47, this fitting part being fixed to the surface of the ski by means of screws 48.
  • the fitting part 47 has a dome part 49 guided in the longitudinal direction 17 of the ski, which is supported under pressure by a resilient element 50 on the end face 51 of the profile body 44.
  • the end face 51 has a rounded region 52, which is arranged eccentrically to the pivot axis 46 of the profile body 44 and compresses the elastic body 50 when the profile body 44 is pivoted.
  • the elastic body 50 presses the profile body 44 into its rest position resting on the surface of the ski.
  • the formation can, as indicated in FIG. 12, be realized particularly simply in such a way that a connecting the underside of the profile body 44, for example at the point designated 53, with the surface 8 of the ski, for example at the point designated 54 elastically stretchable element 55 is provided, which in turn pulls the profile body 44 back into the position in contact with the ski after pivoting about the axis 46.
  • the profile body 56 has tabs 57 projecting laterally over the width of the ski 2, which can be overlapped by the projections 13 on the outer sole contour.
  • the front end region of this profile body 56 is in turn designed analogously to the design of the profile body 16 in order to ensure the necessary positive locking.
  • the flaps 57 result in a widening of the repelling surface when running and enable a smooth lower edge so that the resistance in the snow remains low.
  • the flaps 57 can extend on both sides of the ski over different axial lengths, as corresponds to the ball of the foot and, if necessary, each side can be brought to different heights by inserting parts, for this purpose a central slot 58 in the surface of the profile body 56 is provided.
  • the rear ends of the profile body are again designated as 14 in Fig. 1, so that a certain suspension of the support can be achieved.
  • the profile body 56 can in turn be screwed through the holes 20 put on the surface 8 of the ski 2 are set.
  • FIGS. 14 and 15 show the underside of a cross-country shoe 9, in which the downward extensions 13 are arranged on the outer contour of the sole.
  • the sole extension 10 has on its underside 59 downward-facing edges 60 which cooperate with the edges 18 of the profile body.
  • the front end face 61 interacts with the wall 7 of the profile body, whereby an axial displacement in the sense of the double arrow 62 after engagement in the profile body 1, 16 and 56 is prevented.
  • 63 denotes a plate-shaped profile part, the front end 64 of which cooperates with a resilient locking pin 65.
  • the rear end 66 of the plate-shaped profile part is overlapped by a ski-fixed abutment 67, this abutment having an enlarged head 68 which engages in a recess 69 of the plate-shaped profile part 63.
  • the locking member for the not shown sole extension is designated 70 and pivoted about an axis 71 on the plate-shaped profile part 63.
  • the form- 'positive engagement in the region of the sole extension is ensured by edges 72 and 73 and by a wall 74 in the region of the sole extension.
  • the plate-shaped profile part 63 as can be seen from FIGS.
  • the plate-shaped profile part can also be pivoted laterally in the direction of the arrows 76 about an axis formed by the ski-fixed abutment 67 and directed normally onto the ski surface, which enables a lateral release.
  • a tension member 78 which acts releasably with the plate-shaped profile part 63 and the ski-fixed abutment 67, can be provided. This tension member 78 does not hinder the pivoting of the plate-shaped profile part 63, but has the advantage that after the safety binding has been triggered, the ski remains connected to the plate-shaped profile part 63 and, when the locking member 70 is closed, to the shoe.
