Definitions
- the invention relates to a triggering cross-country binding, which holds a sole part of a cross-country ski close to its toe area in the clamping position ski or elastic fixed, but the heel or heel area of the cross-country shoe can move freely to lift off the top of the ski when running and in case of excessive, between cross-country shoe and Cross-country skiing forces against the resistance of an adjustable locking device triggers, the cross-country ski is held pivotable about a vertical axis of the ski in the ball area against the resistance of the locking device by a plate pivotable on the upper side of the ski about the vertical axis with a binding arrangement for the sole part on a locking bracket attached to the ski is held releasable against the latching resistance.
- Downhill bindings are used completely differently than cross-country bindings, because the ski boot is practically ski-proof in modern downhill bindings and even with outdated downhill bindings compared to cross-country bindings with extremely limited mobility. For this reason, when it comes to downhill bindings, it is largely uncritical where the vertical axis of the ski lies, around which the ski boot rotates when triggered.
- the ski boot rests on a sole plate which is pivotally connected to the ski in the ball area around a vertical axis of the ski and pivotable about a transverse axis in the toe area and is articulated to a heel holder in the heel area, which in turn is articulated to the ski and can be locked in its position holding the sole plate in parallel to the longitudinal axis of the ski.
- a corresponding construction is obviously not possible for cross-country bindings.
- a plate which extends under the ball and toe area of the ski boot is arranged so as to be pivotable about a ski vertical axis passing through the pin by means of a ski-fixed pin arranged in the ball area.
- This plate carries the sole edges of the ski boot in the toe area encompassing side parts which are arranged in a wedge shape in plan view with the wedge tip pointing towards the ski tip in accordance with the shape of the shoe.
- the front edge of the plate in the longitudinal direction of the ski engages under a ski-like plate-like part, so that the plate is held on the ski essentially immovably vertically.
- At the front edge of the plate there is a locking recess into which a spring-loaded locking lever engages with its locking tip when the plate is in its normal position.
- the locking lever is also after tripping, ie. H. After swiveling the plate around the vertical axis of the ski in the ball area and unlocking, the spring force is always applied, so that it can be difficult to return to the locked position.
- a non-triggering cross-country binding in which a sole part of the cross-country shoe is held in the clamping position in front of the shoe cap by means of a holding-down device which overlaps the above-mentioned sole part and which is acted upon by an opening spring which releases the holding-down device from the seeks to urge the sole part in the clamping position to hold the lockable clamping position in an open position releasing the sole part.
- the object of the invention is now to improve a triggering cross-country binding of the type specified in such a way that, on the one hand, a particularly simple construction and, on the other hand, simple handling are provided, the binding in particular after a release without unreasonably high effort in the rest position can be reset.
- the catch carrier is arranged in the direction of the ski tip in front of the vertical axis and a trigger link arranged on the catch carrier at a distance from the vertical axis interacts with a plate-side catch lever, and in that a spring exciting the catch lever against the trigger link is arranged as an opening spring of a hold-down device is which, in its lockable clamping position pressed against the force of the spring on the sole part, secures the clamping position.
- the opening spring of the hold-down device also forms the detent spring according to the invention
- the detent lever is inevitably relieved when the hold-down device is unlocked and can move into its open position. Accordingly, the pivotable plate can be brought into the latching position with particularly little effort after releasing the binding, if the hold-down device is opened beforehand.
- the double function of the spring also ensures a simple and - particularly important for cross-country bindings - weight-saving design because a second spring, separate abutment for two springs and space for accommodating a second spring are saved.
- a second spring separate abutment for two springs and space for accommodating a second spring are saved.
- the plate is held releasably on a pin which can be pivoted with respect to the vertical axis, so that after a safety release, the binding arrangement and the plate can be separated from the ski together with the cross-country shoe connected therewith. Since after the plate has been separated from the ski, the pivoting of the locking lever can no longer be limited by the trigger link, the locking lever performs an additional pivoting under the load on the spring acting on it, which in turn leads to a reduction in the spring force acting on the hold-down device. This relieves the locking or latching elements of the hold-down device accordingly, so that the hold-down device can be unlocked with less effort.
- the plate acts as a catch element, which secures the ski against uncontrolled sliding.
- several recesses can be arranged on the plate or an extension arranged thereon for receiving a ski-fixed pin and thus for determining the vertical axis about which the ski shoe pivots when released.
- side guide elements in the form of pins, pins or wedges or the like can be arranged on the plate or parts connected therewith, which engage in complementarily designed recesses on the shoe sole.
- front or rear C-shaped regions arranged on the plate engage in the longitudinal or longitudinally protruding edge regions of the latch carrier in order to secure the plate against vertical movements relative to the ski.
- the edge regions mentioned are preferably arranged in the form of a circular arc with the arc center falling into the vertical axis, ie. H. the center of the circular arc coincides with the vertical axis around which the ski boot swivels when released.
- the triggering link which is V-shaped when viewed in the longitudinal direction of the ski, can be provided with run-off slopes that slope outwards.
- the cross-country safety binding according to FIGS. 1 and 2 comprises a plate 2 which is arranged on the top of the ski 1 and which carries a binding arrangement 3 of any type in principle.
- the binding arrangement essentially consists of a base plate 4 with front and rear C-shaped bent areas 5 and 6, which comprise a ski-shaped, plate-shaped latch support 7, as well as the shoe sole 8 toe cheeks 9, 9 'and the shoe sole 8 pin 10 securing in the longitudinal direction of the ski and ultimately a hold-down 11 securing the shoe sole 8 against lifting off.
- the hold-down device 11 is designed as a plate-shaped part and on one between the toe cheeks 9, 9 'in the ski transverse direction arranged shaft 12 pivotally mounted.
- the holding-down device 11 can be pressed down from a raised release position against the force of a spring 14 into the clamping position shown by means of a tensioning lever 13 which is also pivoted between the toe pieces 9, 9 'above the same.
- This spring 14 has not only the function of an opening spring for the hold-down device 11, but also the function of a release spring for the binding arrangement with respect to the catch carrier 7. It is therefore designed as a one- or two-part helical spring, the ends 15 of which are spaced apart from one another from below place the hold-down device 11 and its inner ends 16 act on a locking lever 17 mounted on the shaft 12, which interacts with a trigger link 18 on the locking bracket 7.
- the trigger link 18 is V-shaped when viewed in the longitudinal direction of the ski and is designed in coordination with the spring 14 so that in the clamping position shown a secure centering of the binding arrangement and sufficient lateral elasticity during the triggering, as well as the re-engagement of the binding arrangement by means of flat ramp slopes a release is facilitated.
- the combination function of the spring 14 provides an additional advantage in the release position of the holding-down device 11, in that the action on the latching lever 17 and thus the latching force is reduced, so that the binding arrangement together with the plate 2 can be manually separated from the latching support 7, if necessary with little effort leaves, which conversely also leads to the desired relief when re-engaging.
- the plate 2 has an extension 19, which is either firmly connected to the base plate 4 as a separate component made of elastic plastic material or is formed as an integral part of the same.
- a recess 20 is provided, in which a ski-fixed pin 21 engages.
- This pin 21 serves as the fulcrum of the illustrated cross-country ski binding and, by means of its lever arm a, determines the triggering moment for the point of engagement of the latching lever 17 in the trigger link 18.
- cones, wedges or similar lateral guide means 22 can be arranged on the extension 19, which engage in complementarily formed recesses in the shoe sole.
- Bale area B means the area behind the toes in which the ball of the foot transfers significant forces to the cross-country ski. This is particularly the case when lifting the heel and when tackling or climbing uphill.
- the cross-country shoe performs a pivoting movement with respect to this axis together with the plate 2 and the binding arrangement arranged thereon until the plate 2 comes out of the catch carrier 7 which guides it and is separated from Ski 1 together with the cross-country ski boot.
- a complete detachment from the pin 21 is also possible.
- the plate 2 remains connected after a triggering on the pin 21 and thus performs the function of a catch element.
- a suitable catching element such as. B. safety rope or ski brake can be provided to prevent losing the ski.
- a prerequisite for a pivotability of the plate 2 about the vertical axis H is that the edge regions 23, 23 'of the latch support 7, - preferably with a radius around the vertical axis H - are formed in a circular arc.
- the triggering force is therefore determined solely by the latching force of the latching lever 17 acted upon by the spring 14 into the triggering link 18 and the lever arm a, which ensures an exact and reproducible triggering behavior.
- the arrangement of the trigger link 18 above the catch carrier 7 results in an advantage with regard to the assembly and coordination of the catch carrier 7 and the plate 2, since slight inaccuracies in assembly do not have any significant influence on the trigger behavior.
