Definitions

  • the invention relates to a ski binding for a cross-country or touring ski with a holding shell, which is pivoted about a ski-fixed, horizontal transverse axis, both together with a swivel part designed as a two-armed angle lever, and also for the purpose of transition between the closed and open positions first lever arm of the pivoting part carries at least one locking pin, wherein in the closed position of the binding, which is fixed by a resilient bolt, the locking pin of the pivoting part engages in a release of the holding shell and the holding shell engages over a front sole extension of a ski boot, while the locking pin also has an opening interspersed in the sole extension from below, whereas in the open position of the binding the locking pin is removed from the inside of the holding shell, the joint pivoting of the holding shell and pivoting part being fixed to a ski-fixed bearing block
  • the transverse axis moves against an elastic element, the holding shell and the pivoting part being penetrated by the transverse axis in its front region and the pivoting part carrying on its second
  • Such a ski binding is described in WO 87/03211.
  • the side walls of the holding shell are connected by a crossbar which is provided with a locking groove.
  • the pivoting part which can be pivoted about a common transverse axis with a holding shell, has an axis on its upward extension, on which a bolt is articulated with a detent.
  • this locking lug engages in the locking groove of the crossbar of the holding shell.
  • the invention has set itself the task of improving the known ski binding in such a way that the same reliable closing occurs even when snow, ice or dirt accumulations prevent the holding shell from pivoting completely down.
  • a continuous readjustment of the latch is aimed for in the event that the amount of snow or dirt under the holding shell gradually decreases during running.
  • the overall height of the ski binding should be lower.
  • the holding shell has in its front region a crossbar connecting its side walls, which crossbar at its front end as a detent with a roughly in the form of a cylinder jacket section about the transverse axis Surface and with a subsequent, designed in the form of a further cylinder jacket section and extending approximately in the direction of the transverse axis as a holding surface effective second surface is designed that the bolt has a locking area arranged along a cylinder jacket section around the bolt axis and that, in the closed and considered unloaded position of the ski binding, the axis of the holding surface Cylinder jacket section is spaced forward with respect to the axis of the cylinder jacket section forming the latching area, it is ensured that the latching area of the latch engages under the retaining surface of the latch so far that the latching area is reliably closed even without the pivoting of the retaining shell.
  • the design of the holding surface in the form of a cylinder jacket section, the tangential planes of the holding surface and the latching area enclosing an acute angle with one another, enables the bolt to be moved continuously in the closing direction when the dirt underneath the shell subsides.
  • the embodiment according to claim 2 is particularly favorable in terms of shape.
  • FIG. 1 shows an embodiment of the cross-country ski binding according to the invention in longitudinal section, specifically in the position ready for entry
  • FIG. 2 shows the cross-country ski binding from FIG. 1 in the closed but unloaded position (sliding position)
  • FIG. 3 shows the cross-country ski binding as in FIG. 2, but there is an accumulation of dirt or ice below the shell
  • FIGS. 4, 5 and 6 each show a detail of the ski binding according to the invention on a larger scale.
  • front back, top, bottom, etc. are to be understood from the user's point of view; i.e. front means towards the ski tip.
  • a bearing block 30 is mounted on a ski 1 by means of indicated screws 2. It essentially consists of a base plate 31 and side walls 32. The side walls 32 carry a transverse axis 3. A pivot part 40 is on the transverse axis 3 articulated.
  • the swivel part 40 is designed as an angle lever, the first lever arm 41 of which extends rearward and carries an upwardly directed locking pin 42, while the second lever arm 43 points obliquely forward and downward.
  • the second lever arm 43 has on its downward and rearward side a support surface 44 and a projection 45 for a spring 5, which spring 5 is arranged in an elongated recess 33 of the base plate 31.
  • the spring 5 is designed as a helical compression spring and is supported on the one hand on the support surface 44 of the swivel part 40 and on the other hand on a rear boundary wall 34 of the elongated recess 33.
  • the transverse axis 3 also carries a holding shell 50 for receiving a cross-country ski boot 20.
  • the holding shell 50 has an exemption 51 for the locking pin 42.
  • Guide strips 53 adjoin the side walls 52 of the holding shell 50 at the top.
  • the side walls 52 of the holding shell 50 are connected by a crossbar 54.
  • the transverse web 54 is designed at its front end as a latching lug 55, the first surface 56 of which extends approximately in the form of a cylinder jacket section about the transverse axis 3.
  • a second surface or holding surface 57 which is likewise designed as a cylinder jacket section with the radius r H and which extends approximately in the direction of the transverse axis 3.
  • the exact design and position of the surfaces 56 and 57 and that of the associated axes can be seen more clearly in FIG.
  • An expansion spring 6 is arranged around the transverse axis 3 and acts on the swivel part 40 and the holding shell 50 in the sense of a spreading apart.
  • a locking axis 7 extending transversely to the longitudinal direction of the ski is arranged.
  • the locking axis 7 carries a locking bar 60 with a latching area 61 and a recess 62.
  • the recess 62 enables the tip of a ski pole to be inserted to open the ski binding arbitrarily.
  • the locking area 61 is along a cylindrical surface with the radius r R arranged, the axis of which forms the bolt axis 7.
  • FIG. 4 it can also be seen that the axis 9 of the cylinder jacket section forming the holding surface 57 lies in front of the locking axis 7 in the sliding position of the ski binding.
  • An exemption 63 extends below the latching area 61.
  • a locking spring 8 arranged about the locking axis 7 acts on the locking bar 60 in the closing direction.
  • cross-country ski boot 20 with a sole 21 and a hooking element 22 can also be seen in FIG.
  • This cross-country ski boot 20 is known, does not form the subject of this invention and is therefore not described in detail and is shown in broken lines in the drawing.
  • FIG. 1 shows the cross-country ski binding according to the invention in the ready-to-go state and with the cross-country ski boot 20 inserted.
  • the holding shell 50 is pivoted downward against the force of the spreading spring 6, the locking pin 42 penetrating the clearance 51 of the holding shell 50 and projecting into the opening between the sole 21 and the hooking element 22.
  • the first surface 56 of the locking lug 55 slides out of the release 63 of the bolt and thus enables the locking spring 8 to pivot the bolt 60 in the closing direction until the locking region 61 of the bolt 60 comes into engagement with the holding surface 57 of the holding shell 50.
  • This position is shown in Fig.2.
  • the holding shell 50, the swivel part 40 and the bar 60 with the cross-country ski boot 20 now form a movement unit. 4 shows that the holding surface 57 and the latching area 61 come into engagement with one another at point P.
  • FIG. 3 The cross-country ski binding in the closed position is shown in FIG. 3 similarly to FIG. 2, but soiling below the holding shell 50 prevents the latter from swinging completely down. 3 and the associated enlarged illustration according to FIG. 5, that the latching area 61 of the latch 60 engages with the holding surface 57 of the holding shell 50 at another point, namely P ', than is the case in the situation shown in FIGS. 2 and 4, that is to say when the holding shell 50 is pivoted completely down.
  • P ' another point
  • the inventive design of the holding surface 57 and the latching area 61 ensures that the holding surface 57 is sufficiently overlapped over the latching area 61 even if the ski binding or the shoe sole is heavily soiled. A play-free interaction between the holding surface 57 and the latching area 61 is ensured in every conceivable position.
  • the bolt spring 8 automatically moves the bolt in the closing direction when the dirt underneath the holding shell 50 gradually loosens during cross-country skiing.
  • FIG. 6 shows the locking area 61 and the locking lug 55 at the opening point.
  • the opening of the ski binding is achieved by pivoting the bar 60, for example by pressing into the recess 62 of the bar 60 with the tip of a ski pole.
