Definitions

  • the present invention relates to a front board unit for a gliding board comprising two engaging elements having engaging portions adapted to engage opposite side portions of a gliding board shoe, the engaging elements being pivotally supported on the front unit, and a tensioning device which is an elastic Generates force for biasing the engagement portions in the direction of engagement, wherein the tensioning means comprises a slidably held clamping element.
  • the invention is directed to a touring binding as well as to a ski-jumping binding, which are equipped with such a front unit.
  • a front unit of a board binding generally has the task of holding a front portion of a sliding board shoe on the sliding board, wherein the board binding generally further comprises a heel unit, which is responsible for fixing a heel portion of the shoe.
  • the lateral engagement elements in the form of a left and right holding jaws are formed, which overlap a tip of the sliding board shoe and record between them and which are spread apart by overcoming a spring force from each other, so that they release the shoe in the event of a fall (triggering the bond)
  • the gliding board binding In ski-binding, touring bindings or cross-country bindings, the gliding board binding must be adapted to release a heel portion of the gliding board shoe so that it can lift off the gliding board while the gliding board shoe is pivotally supported at a front portion on the front unit about a pivot axis transverse to the gliding board longitudinal axis.
  • the engagement elements of ski-binding and touring bindings for example, storage means which engage in complementary bearing means at opposite lateral front portions of the gliding board shoe to form a pivot bearing.
  • These bearing means are generally formed by projections which engage in corresponding recesses.
  • the engaging portions are biased in the engaged position with the sliding board shoe, on the one hand to promote a secure engagement of the bearing means and on the other hand to ensure a fall triggering of the bond.
  • Clamping device known front units use spiral springs to generate the necessary clamping force.
  • Such springs have the advantage that they are hardly subject to wear, are inexpensive to produce and show a well-defined force behavior.
  • coil springs have a linear motion characteristic and thus act on a slidably held clamping element, a motion conversion between the pivotal movements of the engaging elements and the displacement movement of the clamping element is required. This is generally done by sliding a pivotable lever (for example, the engagement element) on a linearly displaceable guided displacement element. Relatively high frictional forces inevitably occur in the area of the abutment contact between these elements, which on the one hand accelerates the wear of the bond and on the other hand influences the triggering behavior in a manner which is difficult to define.
  • a front board unit for a gliding board comprising two engaging elements having engaging portions adapted to engage opposite lateral portions of a gliding board shoe, the engaging elements being pivotally supported on the front unit, and a tensioning device an elastic force for biasing the engagement portions in the engagement direction
  • the tensioning means comprises a slidably held clamping element
  • the conversion between the pivotal movements of the engagement elements and the displacement movement of the clamping element is effected by a lever mechanism comprising: two according to the engagement elements pivoting lever, a in accordance with the clamping element displaced sliding portion and a hinge member having a first and a second pivot point at which it pivotally m is connected to the levers, and which has a third pivot point located between the first and the second pivot point, at which it is pivotally connected to the displacement portion.
  • the effect of the particular arrangement of the pivot points on the hinge element is that the resulting lever mechanism always converts a pivotal movement of the lever into a substantially linear movement of the displacement section and, conversely, a substantially linear displacement movement of the displacement section is always translated into a pivotal movement of the lever ,
  • this implementation follows from the above-described arrangement of the pivot points on the hinge member relative to the levers and the slide portion, and no linear guide of the slide portion is necessary.
  • the lever mechanism according to the present invention operates on the basic principle of a Watt-linkage for implementing the pivotal movement of two hinged respectively at fixed anchorage lever in an approximately linear movement.
  • lever mechanism An important advantage resulting from the use of the lever mechanism according to the invention is that the motion conversion can be realized completely without the use of a linear guide and without the use of elements derived from each other. Instead, the elements of the lever mechanism are pivotally mounted to each other at pivot points. Rotary bearings can be manufactured with excellent power transmission characteristics and only low friction losses. In addition, the bearing surfaces of pivot bearings are generally mutually covered, so that penetration of impurities, snow and moisture is inhibited and thus these bearings have less wear than linear guides, cam mechanisms, cam mechanisms or the like.
  • the two levers of the lever mechanism are formed by the engagement elements themselves, ie the engagement elements are directly coupled to the first and second pivot point of the joint member, so that the lever mechanism according to the invention can be manufactured with a small number of parts.
  • the engagement elements are pivotally supported about a vertical axis (Z axis) so that the low height engagement elements can be mounted over the gliding board.
  • the engagement members can then engage the front portion of a gliding board shoe like a pliers from the front.
  • each of the two engagement elements is pivotally mounted on a bearing portion on the front unit and extending from the bearing portion to the engagement portion extending first lever arm and extending from the bearing portion to the joint member second lever arm. It is thus possible to position the hinge element in a suitable position in front of the sliding board shoe by constructing the second lever arm with a corresponding length and a corresponding angle to the first lever arm.
  • Engagement elements of this type may in particular have an L-shape and the second lever arms may point towards a longitudinal central axis of the front unit.
  • Such a construction allows the arrangement of the joint element substantially in the region of the longitudinal central axis of the sliding board and in particular also a displacement movement of the displacement section approximately in Gleitbrettlnaturesraum, so that the space available on the sliding board space can be effectively used.
  • the displacement portion of the lever mechanism may preferably be formed on the tension member, so that the displacement movement of the displacement portion generated by the lever mechanism can be used directly for the movement of the clamping device without further transmission of motion and thus results in a simple construction of the front unit.
  • the clamping device for biasing the engagement portions may comprise a spring means which is supported on the clamping element, so that the elastic force can be transmitted directly to the displaceably arranged clamping element in particular by a spring element with linear motion characteristic.
  • the spring means can then be supported on the one hand on the clamping element and on the other hand on a sliding board-fixed spring bearing.
  • the clamping element can pass through a recess of the spring bearing, so that the clamping element can move in the recess and thus can be arranged to save space.
  • the clamping element can also enforce the spring means, so that the claimed space on the sliding board can be further reduced.
  • the front unit further comprises a user-operable operating member for moving the engaging portions between an engagement position in which the engaging portions engage a sliding board shoe and an open position in which the engaging portions release the sliding board shoe.
  • a manually operated actuating element which can be operated by the user, for example by hand or with the aid of a ski pole, it is then possible, for example, to move the engagement sections into an open position before entering the binding, ie in particular to remove them from each other, that the sliding board shoe can be positioned between the engagement portions.
  • an actuator may be adapted to allow exit from the binding by bringing the engagement portions into the open position by manual operation of the actuator.
  • the transition from the open position into the engaged position in variants of the invention also by manual Operation of the actuating element, for example, by operation in the opposite direction compared to the operation for adjustment in the opening direction.
  • the front unit for facilitated and accelerated use may have an entry mechanism which, upon entering the binding by exerting a compressive force from the sliding board shoe on the front unit, causes a partial or complete automatic adjustment of the front unit from the open position to the engaged position.
  • the technical effect of the above-mentioned actuating element may be to move the elements of the front unit held under relatively high pretension, in particular the engagement elements and the elements of the lever mechanism, by the actuating element with a suitable force reinforcement or leverage between the engaged position and the open position, so that a comfortable operation of the front unit is made possible.
  • a front unit which is equipped with an above-described, manually operated actuator
  • the actuating element is pivotally coupled to a first actuating pivot axis with a sliding board-fixed portion of the front unit
  • the actuating element on a second actuating pivot axis is coupled to an actuator and that the actuator is pivotally connected to a member of the lever mechanism, with one of the engaging elements or with the clamping element on a third actuating pivot axis, wherein upon movement of the actuating element between the engaged position and the open position, the second actuating pivot axis passes a dead position, in which it intersects a connecting line between the first actuating pivot axis and the third actuating pivot axis.
  • the elastic force generated by the tensioning means can be utilized not only for the bias of the engaging portions but also for the reliable locking of the operating member, both in the open position as well as in the engaged position.
  • the actuating element is held securely by the force of the clamping device, wherein the direction of the force action (towards the open position or towards the engagement position) is reversed at the dead center.
  • the invention is further directed to a touring binding which comprises a front unit of the type according to the invention described above.
  • a touring binding which comprises a front unit of the type according to the invention described above.
  • the saving of weight and size of the front unit plays a particularly important role, so that the simple and easy construction of the front unit according to the invention achieves particular advantages with such bindings.
  • Touring bindings are also subject to particularly high mutual loads during ascent and during subsequent descent, so that the low-wear and well-defined due to low friction movement characteristics of the binding according to the invention can be used particularly advantageous here with frequent change between engagement position and open position.
  • the engagement portions each having a protruding coupling pin, wherein the coupling pins of the two engagement portions facing each other.
  • the present invention relates to a ski-jumping binding comprising a front unit of the type described above.
  • the mechanical properties and functional characteristics of the gliding board binding play an outstanding role, which is due to the athletic character as well as the inherent danger of this sport.
  • Decisive for the success of the competition and for the safety of the skijumper are thus the reliability of the gliding board binding as well as the accuracy with which a state of engagement between shoe and binding and a release behavior of the binding in the case a fall are defined.
  • Ski jump bindings of the abovementioned type can in particular have engagement sections each with a coupling recess for receiving a coupling projection projecting laterally from a front section of a skijack so that the coupling principle known per se can be used for the pivotable mounting of the skijack for the ski binding engagement according to the invention.
  • the coupling protrusions are then forced out of the respective coupling recesses by the forces acting on the binding from the shoe, the engagement sections being spread open against the spring force of the tensioning device.
