Definitions

  • the invention relates to a safety ski binding with a bearing block that can be swung out laterally about a vertical axis against the force of a return spring and relative to a base plate that can be displaced parallel to the upper side of the ski, with a latching rocker that is loaded by a release spring and that interacts with a bearing block that is fixed to the bearing block and that is mounted against pivoting of a bearing block on the bearing block
  • Sole holder acts in the vertical direction, with a preferably base plate-fixed control track and a locking element associated with this control track, preferably formed on the sole holder for controlling the lateral release between base plate and sole holder, with a release lever acting directly or indirectly on the locking rocker for arbitrary release of the binding, and with a preferably spring-loaded, at least with involuntarily opened binding in the locked position, a lateral pivoting of the bearing block against the base plate inhibiting locking elements t.
  • a locking element is provided which, on the one hand, swings the bearing block out sideways when the binding is closed Prevent vertical axis and on the other hand should not hinder the diagonal release process (vertical and lateral pivoting of the bearing block when releasing the binding).
  • the locking element is designed as a locking attachment which is attached to a housing part which pivots up with the sole holder.
  • this locking lug engages in a recess with little play and thus prevents the sole holder from turning laterally about a vertical axis.
  • a disadvantage of this binding is that when entering the binding, the locking projection already exits the recess before the locking of the locking rocker (closing of the binding) is secured, so that there is also a risk of permanent lateral loading when entering the binding Binding triggers laterally before locking.
  • Another disadvantage of this binding is that the recess, in which the locking lug should engage, lies outside the binding housing in the open and there is therefore a risk that a correct engagement of the locking lug in the recess can be hindered by icing.
  • the object of the invention is to provide a safety ski binding of the type mentioned in the introduction, in which the locking element prevents the pivoting of the bearing block, and thus the sole holder, from the centered central position, even in difficult terrain with constant lateral load, but without pivoting sideways to inhibit the sole holder during the release process. Furthermore, the functionality of the binding, in particular the blocking element, should not be impaired by external influences such as ice and snow.
  • the locking rocker or a component rigidly connected to it has a control zone actuating the locking element, the locking element in every position of the locking rocker, in which it engages under the locking lug, in a disengaged, lateral pivoting out of the bearing block the base plate releasing position is held.
  • the control zone moved with the locking rocker allows precise control of the locking element, in particular with regard to whether the binding is locked or not. If the locking arm only partially engages under the locking lug when boarding, the binding snaps shut under the action of the release spring and is locked. Exactly in that position of the locking rocker in which a locking of the binding is already ensured when the binding is closed, the control zone directly connected to the locking rocker actuates the locking element which has been locked until now when the binding is closed, this in every position of the locking rocker in which it is engages under the locking lug, is held in a disengaged position, releasing a lateral pivoting of the bearing block relative to the base plate.
  • the locking element is preferably spring-loaded. According to one feature of the invention, it is advantageous if the locking element is designed as a resilient component, because a separate component, such as a leg spring acting on the locking element, can be saved.
  • a preferred embodiment of the invention is that the locking element consists of a substantially horizontally lying spring tongue which is preferably attached to the bearing block and which engages or engages in a counter-latching under its own spring action when the binding is in the middle position and is not acted upon by the latching rocker.
  • a horizontal spring tongue takes up little space and can therefore be arranged well protected from ice and snow, for example inside the bearing block.
  • a hindrance to the diagonal release i.e. a blocking of the pivoting out of the bearing block at the side
  • a spring tongue apart from the fact that a blocking effect of the blocking element only occurs when triggered when the binding is already unlocked in the vertical direction be avoided that the spring tongue has at its free end a recess delimited by two projections into which an angled locking tooth forming the counter-locking engages when the locking element is in the locked position, the spring tongue when the bearing block swings out to the side when the binding is released by engaging one the extensions at the angled end of the ratchet tooth are stable against their spring action in the disengaged position.
  • the extensions come under the angled end of the locking tooth, where they then hold the locking element in a disengaged position, completely releasing a lateral pivoting of the bearing block, regardless of the position of the locking rocker, until the binding is released after the ski shoe has been released the sole holder is guided into a centered central position by a return spring.
  • the locking element designed as a spring tongue locks under its own spring action on the locking tooth, and the binding is thus ready for entry.
  • Such a horizontal spring tongue can be actuated in a simple manner by a control zone which is designed as a nose on the locking rocker and points essentially towards the base plate.
  • Another embodiment with a likewise very space-saving and structurally favorable locking element consists in that the locking element is formed by an elastic component articulated on two offset axes on the bearing block and which can at least be disengaged from the torque by the control zone.
  • the locking element is perpendicular to the base plate in the closed position of the binding and has a recess or an extension at its end facing the base plate, which, when the locking element is locked in position a base plate-fixed counter-locking interacts.
  • a lever having the control zone is particularly suitable, which is attached or formed laterally next to the latching projection of the latching rocker cooperating with the latching lug and coaxially with the latching rocker, the steering zone facing the area of the sole holder holding the shoe is.
  • the control zone then lies against the spring-loaded locking element in the event of an involuntary vertical opening or closing of the binding and moves the locking element, which is designed as an elastic component, into a locked or a disengaged position, depending on the position of the locking rocker. This ensures an optimal locking function or centering function of the locking element when entering the binding with the simultaneous possibility of unhindered lateral release of the binding in the event of a fall.
  • the locking element has, in addition to the locking area interacting with a counter detent in the central position of the binding, for example in addition to a recess, contact surfaces which the locking element engages by resting on or next to the counter detent when the bearing block swings out to the side when the binding is released Hold against a spring action in the disengaged position until a return spring centers the bearing block, whereupon the locking area of the locking element locks with the counter-locking.
  • a further object of the invention is therefore to create a safety ski binding with a locking element which can be easily disengaged for demonstration purposes.
  • the invention provides that the locking element can be released indirectly or directly by the release lever for arbitrary release of the binding. If the binding is triggered arbitrarily (actuated release lever), diagonal release or a lateral pivoting of the sole holder can be demonstrated in advance without having to accept the disadvantage of using the binding on the slopes.
  • the control of the locking element by the locking rocker is particularly favorable because then a lifting of the locking rocker caused by the release lever from the control surfaces adjoining the locking lug can be used to open the binding at the same time for controlling the locking element in the disengaged position. It is advantageous if the blocking element is pivoted into an unlocked position without being acted upon by the control zone or a control groove.
  • a third preferred embodiment of the invention is based on a ski binding, as shown in DE-A1-32 04 468.
  • the ski binding disclosed there essentially relates to a safety ski binding with a bearing block that can be swung out laterally about the vertical axis against the force of a return spring and with a bearing block that is loaded by a release spring and that interacts with a bearing block-fixed latching lug that prevents a bearing block from pivoting on the bearing block
  • Sole holder acts in the vertical direction, preferably with a control track fixed to the base plate and one of these taxes track associated, preferably formed on the sole holder locking element for controlling the lateral release between the base plate and sole holder, with a release lever acting indirectly or directly on the locking rocker for arbitrary release of the binding, and with a spring-loaded, at least in the case of involuntarily opened binding in a locked position, swinging out to the side the bearing block against the base plate inhibiting locking element, which consists of a spring-loaded torque with a two-armed
  • the binding at least in the initial phase of the closing process, is held in a centered central position even when loaded sideways.
  • the disadvantage here is that snow and ice can impair the functionality of the component which is exposed and unprotected under the binding housing when the binding is open and is designed as a two-armed lever.
  • Another disadvantage of this known binding is that the position of the binding housing, which actuates the lever or the component with its edge, is not directly decisive when boarding, whether the binding is actually locked, i.e. whether the detent rocker acted upon by a release spring Engages under the latch or the role. So there is a risk that the locking element (lever or). When the component gets in before the locking of the binding, the bearing block or the sole holder swings out sideways and the binding swings out laterally, for example on a steep slope before locking, with constant lateral load.
  • the configuration of such a safety ski binding according to the invention in which the locking element can at most also be disengaged by the release lever, consists in that the second arm of the locking element is provided with a guide part which, in a pivoting region of the sole holder lying between the open and closed positions of the binding, also includes the sole holder moves with the control grooves, and that the guide part in the closed position and in the open position of the binding does not engage in any of the control grooves and the position of the locking element at least in the region of one of these binding positions is formed by a component on the locking rocker or on a component rigidly connected to it Tax zone is set.
  • Two concentric control grooves are advantageously provided, the guide part of the locking element sliding in the first control groove when the binding is closed and the locking element being locked, and the guide part sliding in the second control groove when the binding is triggered involuntarily and the locking element being disengaged.
  • the control grooves hold its position (locked or disengaged), it being essential that the position of the locking element not only from the current one Binding position depends, but also on whether a closure or a triggering of the binding takes place.
  • a kind of "hysteresis" of the blocking element position is achieved depending on the binding position.
  • the locking element When opening (releasing) the locking element is always disengaged and thus does not inhibit diagonal release in any way.
  • closing (getting in) the locking element is locked at least until the locking rocker engages under the locking lug and thus prevents the sole holder from swinging out to the side, which is undesirable here.
  • the locking element can be additionally disengaged by the release lever for arbitrarily releasing the binding.

In this way, on the one hand, an unimpeded pivoting movement of the bearing block 6 is ensured and, on the other hand, the bearing block 6 is additionally secured against lifting off from the guide plate 4.
  • the heel holder 3 is blocked against a purely lateral release by the latching recess 13b of the control cam 13a.
  • the front jaw, not shown, is therefore responsible for a purely lateral triggering process. If composite, so-called diagonal forces occur, the control curve 13a of the latching part 13 comes into effect after overcoming the blocking zone, which causes the sole holder to be pivoted sideways.

If the heel holder 3 shown in the downward position in FIG. 1 is to be opened, the release lever 20a together with its driving axis 21 is pivoted up. Due to the upward moving axis 21, the spring housing 12 pivots clockwise and the locking rocker 16 counterclockwise, so that the locking projection 16a no longer engages under the locking lug 17 and thus the sole holder 8 together with the locking rocker 17 upwards, into a position releasing a shoe, not shown can pivot.
