Definitions

  • the invention relates to a safety ski binding for downhill or touring shoes according to the preamble of claim 1.
  • ski bindings so-called center bindings
  • center bindings have certain advantages compared to bindings with a cheek-heel system.
  • the friction in a horizontal release process is significantly reduced, since the plate on its ski-fixed axis of rotation has to overcome a much lower friction in a horizontal release than that in a shoe that is clamped between a heel holder and a toe piece and slides on the top of the ski, the case is.
  • different shoe sizes do not have a negative effect on the triggering moments, since the distance from the front and rear holding members to the pivot point is the same, with standardized shoe soles or plates being attached to shoe soles between the front and rear holding members.
  • the triggering process for horizontal triggering is usually accomplished in such binding systems in that a sensor mechanism measures the pivoting of the plate relative to the ski or the torque caused thereby, and passes this information on to the heel holder, which triggers above a certain horizontal torque and when there is also a vertical moment that the shoe releases.
  • a ski binding of the type mentioned at the outset is described in WO-A-82/02495.
  • a front jaw that can be folded down is mounted at the front and a heel holder that reacts to both vertical and horizontal forces and triggers when overloaded.
  • the horizontal pivoting of the plate is controlled by a roller that is spring-loaded to an angle lever on the plate and that rolls on a control curve that is attached to the rear end of the base plate.
  • the angle lever has an extension, which causes the heel holder to open when the swivel angle of the plate is too large.
  • the spring acting on the angle lever and the spring which controls the vertical release of the heel holder are nested one inside the other and their spring force is adjustable via a screw.
  • the vertical release of the heel holder is regulated by a multi-part strap system.
  • the release lever is a separate part that engages in the tab system if necessary.
  • the invention has set itself the task of creating a ski binding of the type mentioned, in which the resetting of the plate via a differently designed control mechanism and the adjustment of the spring force of the first spring restoring the plate via a differently designed biasing mechanism.
  • the front and rear holding members should have a constant distance from one another for all shoe sizes.
  • the heel holder only responds to vertical forces.
  • the invention now makes it possible to create a ski binding in which the accommodation of the pivoting-back device of the plate, which consists of a first spring, a pretensioning mechanism and a control mechanism, lies partly inside the plate and thereby saves space and weight is coming. Due to the local separation of the springs, which monitor the horizontal pivoting of the plate and the vertical pivoting of the sole holder, the preloading mechanisms are also separated, making it easy to change the two spring preloads independently of one another.
  • the elongated design of a plate binding is used by the configuration of the control mechanism according to the invention.
  • the constant distance between the front and rear holding element ensures that torque is transmitted from the shoe to the ski at the same moment for all shoe sizes. Since the heel holder only responds to vertical forces, it is simple and made from just a few components.
  • a further embodiment of the invention is characterized in that the holding jaws and the heel holder, as known per se, have grippers which engage in opposing grip recesses of the shoe, the grip recesses being designed to taper inwards.
  • the holding jaws have two inclined surfaces, each lying in one plane, which extend essentially normal to the top of the plate and enclose an angle of 30-100 °, preferably about 80 °, the The line of intersection of the planes, viewed in the direction of travel, lies in front of the holding jaws and the lower shaft part of the shoe has points which are designed to be opposite to these inclined surfaces.
  • the inclined surfaces advantageously convert the horizontal forces acting on the jaws into forward forces.
  • the opposing surfaces in the shoe sole reinforce this effect.
  • the recessed grips are set back from the front and rear end regions of the lower shaft part of the shoe, as is known per se, so that when the shoe is clamped in, these end regions protrude at least partially from the front holding member and the heel holder, the underside at least the front end region of the lower shaft part lies in approximately the same plane as the sole of the shoe and extends obliquely upwards at an acute angle of approximately up to 15 °.
  • This configuration gives the shoe very safe walking behavior. As a result, walking on difficult passages, such as stairs, is made easier and the user's surefootedness is significantly increased, as a result of which the falls which have hitherto been common in similar shoe shapes can be avoided.
  • the holding jaw preferably the entire front holding member, as in a further embodiment of the invention, can be pivoted in the longitudinal direction of the ski about a transverse axis mounted in the plate, the pivoting position of the holding jaws being below the upper side of the plate. which is connected to a thrust moment in the longitudinal direction of the ski, the holding jaw is pivoted under the top of the plate, which means that the shoe is released not only from the side but also from the front when the shoe is released.
  • the holding jaws or the front holding member by at least one spring, for. B. a leg spring, is applied in its operative position that the holding jaw or the front holding member is held in operative position by a nose on a support of the ski-fixed base plate, and that the dimension of the support, viewed transversely to the longitudinal direction of the ski, the elasticity range of the binding for determines the horizontal release.
  • control curve is formed on the edge of a flat recess of the slide formed as a flat piece, which recess also receives the abutment of the first spring, this being arranged on the end region of the slide opposite the control curve.
  • This flat design of the slide enables a low overall height, which takes into account the requirement for the smallest possible distance between the top of the ski and the foot of the skier, and on the other hand, the slide is easy to manufacture and the entire measuring and control mechanism can also be optimally integrated into the plate.
  • the slide is guided longitudinally by guide elements which are arranged on the base plate or plate, these guide elements, according to a further feature of the invention, being rollers which are mounted on vertical axes.
  • the guide elements can be grooves in which the outer edge of the slide slides.
  • the roller on which the slide is supported with its control cam is arranged on a downwardly projecting bolt which is fastened in or on the plate.
  • the characterizing features of claim 9 represent an alternative arrangement of roller and slide, the roller being fixed to the base plate and the slide being guided on the plate.
  • the pretensioning mechanism consists of at least one angle lever mounted on a vertical bearing axis fastened to the base plate, one arm of which carries a screwing device mounted in a lateral recess of the base plate, and the other arm acts on the spring plate of the first spring.
  • a further embodiment of the invention is characterized in that the spring plate of the first spring is arranged within the recess of the slide and that the prestressing mechanism acts on the spring plate so as to be longitudinally displaceable.
  • the first spring can also be optimally integrated within the slide.
  • the pretensioning mechanism For a tilt-free function of the pretensioning mechanism, it makes sense if it consists of two angle levers, which are kept parallel at a constant distance from each other by the spring plate and an engagement part for the screw. The function of the adjustment is reliably ensured without unnecessary material expenditure and the spring plate is guided optimally, which also largely avoids any deflections during driving.
  • the heel holder has a two-armed Sole hold-down device, one arm, as known per se, which represents the gripper which is in engagement with the recessed grips and at the same time is acted upon by the shoe, while the second arm represents a release lever which has a cam on its free end region remote from the grippers, which one by at least one second spring loaded locking part, for example a locking roller, presses against a locking link. Due to the one-piece design of the release lever with the sole holder, space and weight are saved and the heel holder is simpler because it has one component less. In addition to a small size, the heel holder is characterized by high operational reliability.
  • the locking roller is mounted on a pull rod, which pull rod, as known per se, engages via an adjusting device at the rear end of the second spring.
  • FIG. 1 shows a section of the front part of the binding up to the vertical axis
  • FIG. 1a shows a section of the toe area of the shoe
  • FIG. 2 shows the rear part also a section of the vertical axis
  • FIGS. 3 and 4 show details on an enlarged scale
  • FIG. 3 showing the prestressing mechanism in plan view
  • FIG. 4 the area of the front holding jaw and the control mechanism with the plate partially removed.
  • an embodiment of the ski binding according to the invention consists of a base plate 1 which can be mounted on the top of a ski and which has overlaps 2 and 3 in the front and rear area, respectively, which serve to guide a plate 5 without play, which is rotatably mounted about a vertical axis 4.
  • the vertical axis 4 is formed by a cup-shaped recess in an elevation of the base plate 1, in which cup-shaped recess an opposing elevation of the plate 5 engages.
  • the plate 5 carries in its front area on a transverse axis 7 a pivotable front holding member 6.
  • the front holding member 6 projects with its area designed as holding jaws 46 over the top of the plate 5 and is supported with a nose 9 against a base plate-fixed support 8.
  • Der Holding jaw 46 has two grippers 47 which engage in recesses 48 on the shoe 17 and thus hold it in the binding.
  • the recessed grips 48 have holding surfaces 50, which come into direct engagement with the grippers 47, and furthermore have surfaces 51 and end surfaces 52 lying opposite them.
  • the shoe 17 has a sole 58 on its underside. Similar to the front region 55 of the lower shaft part 57, two grip recesses 49 are formed on the rear region 56 of the lower shaft part 57 of the shoe 17, which are each delimited by a holding surface 27, an end surface 54 and an entry surface 32 opposite the holding surface 27. The front end region 55 of the lower shaft part 57 of the shoe 17 and the rear end region 56 of the lower shaft part 57 protrude beyond the grip recesses 48 and 49, respectively.
  • the underside 64 of the end regions 55 and 56 can also extend forward and backward from the level of the sole 58 run at an acute angle, as shown for example in Fig. 1a. The underside 64 extends obliquely upwards at an angle of approximately 15 °.
  • the recessed grips 48, 49 are designed to widen outwards and their end faces 52, 54 are at a distance from the grippers 47, 25 when the shoe is inserted, thereby preventing the recesses 48, 49 from becoming clogged by ice or snow.
  • a sole hold-down with its grippers 25 engages in a top view in the form of a fork.
  • the sole hold-down is integrally connected to a release lever 24 and a cam 29 arranged thereon and is pivotably mounted about a transverse axis 28.
  • the holding surface 27 of the recessed handles 49 is opposite the entry surface 32.
  • the entry surface 32 acts on the upper side of the grippers 25, which is designed as a tread surface 26, and thereby brings them into the holding position.
  • the open position of the sole hold-down is shown in broken lines in FIG. 2.
  • the torque which arises when the plate 5 swings out horizontally about its vertical axis 4 is measured by a measuring and control mechanism 44.
  • the measuring and control mechanism 44 has a flat slide 11 with a recess 59, the boundary surface of which on the slide 11 forms a control cam 12 which is acted upon by a roller 13 which is mounted on a plate-fixed bolt 14.
  • a recess 59a is formed, which serves to receive a first spring 10 and an abutment 15.
  • the other end of the first spring 10 abuts a spring plate 34 and is acted upon by a pretensioning mechanism 16, which will be explained in more detail later.
  • the slide 11 is guided laterally by guide elements 60 which are designed as rollers 61 which are rotatably mounted about axes 62 fixed to the base plate.
  • guide elements 60 force the slider 11 forward in the longitudinal direction of the ski. This forward movement also pushes the abutment 15 forward, which further compresses the first spring 10.
  • the holding jaw is triggered according to a certain swivel angle, which is defined by the support 8.
  • the nose 9 of the front holding member 6 slides along this support 8 in the course of pivoting the plate 5 until it reaches the end of the support 8 and then pivots forward about the plate-fixed pivot axis 7 or under the top of the plate 5.
  • This process is supported in particular by inclined surfaces 53 on the holding jaws 46, which are formed on the inside of the holding jaw 46 facing the shoe 17 approximately perpendicular to the upper side of the plate 5 and form an angle a between 30 ° and 100 °.
  • the shoe 17 has the inclined surfaces 53 of the holding jaw 46 with opposing inclined surfaces and presses on its torsion relative to the binding on one of the inclined surfaces 53.
  • the lateral moment for the front holding member 6 or for the holding jaws 46 is converted into a forward moment, whereby the Holding jaws 46 is pressed forward.
  • the jaws 46 pivot forward. This pivoting is intensified in the event of a possible thrust moment of the shoe 17 in the longitudinal direction of the ski.
  • the preload of the first spring 10 and thus the pivoting moment leading to the release is set by the preload mechanism 16, as can be seen in the upper half from FIG. 3.
  • This pretensioning mechanism 16 is provided only on one side and essentially consists of two superimposed angle levers 35 (see FIG. 1) which are congruent in plan view and a screwing device to be described in more detail.
  • the angle levers 35 are pivotally mounted about a bearing axis 36 fastened to the base plate 1.
  • One arm of the angle lever 35 receives the spring plate 34 for the first spring 10 on a pivot axis 38.
  • the other arms of the angle lever 35 carry, via a further swivel bracket 37, an engagement part 39 which serves as a thread-carrying nut for a screw 40.
  • the screw 40 is mounted in a recess 43 of the base plate 1 and carries a screw head 42 which can be operated on the side of the base plate 1 by means of a screwdriver. To be protected as possible, the screw head 42 is partially covered in a recess 41 in the base plate 1. Attack part 39, screw 40 and their head 42 form the screw device. If the screw 40 is now rotated, the axial position of the engagement part 39 on this screw 40 changes, as a result of which the pivot axis 37 is also displaced in one direction or the other. As a result, one arm of the angle lever 35 is pulled in one direction or the other, whereby its other arms press the spring plate 34 against the first spring 10 or yield in the sense of spring tension.
  • the heel holder 45 essentially consists of the sole hold-down device described above, which is approximately fork-shaped in plan view, with the grippers 25, the release lever 24 and the cam 29.
  • the cam 29 has a sliding surface 30 and a pressure surface 31, with the heel holder 45 closed the sliding surface 30 acts on a locking roller 20.
  • the locking roller 20 is mounted on a pull rod 19 which acts on a second spring 22 via a conventional adjusting device 23. If the sliding surface 30 now pushes the locking roller 20 forward along a locking link 33, the second spring 22 is thereby tensioned and is supported against a plate-like abutment 63.
  • the latching link 33 is designed such that it has a latching pan 21 into which the latching roller 20 engages in a certain way, as a result of which the latching roller 20 is printed into the latching pan 21 by means of the pressure surface 31 of the cam 29.
  • This position of the locking roller 20 is drawn in dashed lines. It is only when the binding is re-entered or the heel holder 45 is closed by hand that the locking roller 20 is pulled back into its starting position by the force of the second spring 22.
  • the housing 18 for the second spring 22 is formed in one piece with the plate 5.
  • the oblique surfaces 53 and the oppositely designed surfaces on the shoe 17 convert the torsional moment into a forward moment and the front holding element 6 pivots around axis 7 to the front and thereby releases the shoe.
  • a leg spring, not shown, then swivels the front holding member 6 back into the holding position and the first spring 10 pulls the plate 5 back into the downward position by the force of the control cam 12 on the roller 13.
  • a vertical release is caused by a tightening torque of the shoe 17 in the vertical direction in that the holding surface 27 of the recessed grips 49 press the sole hold-down device or its gripper 25 upwards, causing the release lever 24 and the cam 29 connected to it in one piece to move around common axis of rotation 28 are pivoted.
  • the cam 29 acts on the locking roller 20 with its sliding surface 30 until it snaps into the locking pan 21.
  • the tip of the cam 29 slides over the locking roller 20 and the pressure surface 31 of the cam 29 comes into contact with the locking roller 20 and thereby presses it into the locking pan 21.
  • the pull rod 19 which carries the locking roller 20, the second Spring 22, which has its own adjusting device 23 of the bias of the spring force, further compressed.
  • the ski boot is free.
  • the re-entry takes place by acting on the tread surface 26 of the grippers 25 through the entry surfaces 32 at the rear end region 56 of the shoe 17.
