Definitions

  • the present invention relates to a snowboard binding, as has become known for example with the subject of DE-GM 90 14 833.
  • the known locking and release device had the disadvantage that there was no safeguard against unintentionally closing a binding once triggered, so that it could happen that when the front binding was triggered, for example, the rear binding also triggered, but that - provided the sole plate is off the rear binding was not released, the rear binding then closed again and connected the sole plate to the snowboard in an undesirable manner, which was associated with a high risk of accident for the driver's foot held in the rear binding.
  • the present invention is therefore based on the object of developing a snowboard binding of the type mentioned in such a way that an inexpensive and reliable locking and triggering device is created which is protected against the ingress of snow, ice and water.
  • the invention is characterized by the technical teaching of claim 1.
  • An essential feature of the invention is that, starting from a tension ring arranged rotatably in the front and rear binding, each cable pull opens into the locking and release device according to the innovation, and that each cable pull is assigned its own latching action on a pivot lever connecting the two cable pulls, which Swivel lever forms a common catch with a common opening lever.
  • a lock against unintentional reclosing of the front and rear binding is provided in such a way that the latching device, once triggered, is locked in an open position and is only brought out of this locked open position by manual actuation of the pivot lever into the closed position can.
  • cable pulls (wire ropes) has the essential advantage that there are no push rods and connecting rods prone to twisting, and that such wire pulls are protected against twisting of the board in the field, because these wire pulls are laid in the area of loosely laid Bowden cables, which Bowden cables are laid on the snowboard with a large amount of movement, so that even twisting of the snowboard does not influence the wire rope laid in the bowden cable.
  • Another advantage of the locking and triggering device according to the invention is that relatively inexpensive stamped and bent parts can be used, and that costly castings can be dispensed with.
  • a snowboard 19 is shown schematically in FIGS. 1 and 2, which has a front binding 20 and a rear binding 21 in a manner known per se.
  • a locking and release device 22 is located between the two bindings 20, 21.
  • the triggering processes between the bindings 20, 21 are synchronized here via Bowden cables 24, 25, wherein a Bowden cable 24, 25 starts and starts from a binding 20, 21 one side of the locking and triggering device 22 opens.
  • the bindings 20, 21 are shown in FIG. 1 and 2 with the sole plate 22 removed, in order to show the inner locking ring 23 and to show that the locking ring 23 is surrounded on its outer circumference by a fixed retaining ring 27, which in turn is attached to its outer circumference is surrounded by a rotatably mounted clamping ring 48.
  • each locking ring 23 has on its outer circumference a series of locking recesses 36, in which spring-loaded locking bolts 29 engage in assigned locking recesses 36 in the region of the locking ring 23.
  • the locking ring 23 can either have 3 evenly distributed locking recesses 36 according to the circumference; however, it can also be designed as a locking ring 23a, which has a locking groove 52 on the circumference, into which the spring-loaded locking bolts 29 engage.
  • the outer circumference of the entire locking ring is designed as a spherical body 30, which is shown completely in FIG. 6 for better clarification, the locking ring 23 itself corresponding only to the part which is shown in FIG. 6 with solid lines.
  • the design of the outer periphery of the locking ring 23 as a spherical body 30 has the advantage that it can move freely in the region of the recess 28 in the manner of a spherical shell without jamming.
  • the triggering behavior of the locking ring in the area of the associated recess 28 is thus substantially improved in all directions.
  • FIGS. 7 and 8 show details of the locking and unlocking device 22 according to the innovation.
  • the lower illustration in FIG. 7 corresponds to a plan view of the lower half of the locking and triggering device 22, while the half section shown in FIG. 7 represents a section along the line VII-VII in FIG. 8.
  • the distinction between the right and left part of the locking and triggering device 22 is important for the further description, because it can be seen from FIG. 1 that the Bowden cable 24 coming from the front binding 20 opens into the upper part of the locking and triggering device while the Bowden cable 25, which is guided from the rear binding 21, is inserted into the lower part of the locking and triggering device 22.
  • the function of the locking and triggering device 22 is described below for the application when a trigger cable acts in the direction of arrow 51 on the wire cable 12a associated with the front Bowden cable 24.
  • the wire rope 12a is sealingly passed through a housing, not shown, and is fastened to its clamping part 9.
  • This clamping part 9 is firmly connected to a spring element 6, which spring element 6 is pivotally mounted in the area of a bearing pin 10, which bearing pin 10 passes through a pivot bearing 7 which is pivotally mounted in the area of a pivot bearing pin 11 fixed to the housing.
  • the spring element 6 carries on its rear part an adjusting screw 8, which is held in the spring element 6 with a corresponding thread adjustable in length.
  • the adjusting screw 8 forms a rear stop for a compression spring 5, the front end of which is supported on a guide part 4 which is displaceably guided in the spring element 6.
  • a spring element bearing pin 14 is arranged, which is arranged on the pivotable part of a pivot lever 2.
  • the pivot lever 2 is pivotally mounted about a pivot lever bearing pin 18 fixed to the housing.
  • a push rod 13 is also pivotally mounted, which has an elongated hole 32 in its front part, which is aligned with its longitudinal axis parallel to the longitudinal axis of the push rod 13.
  • a locking pin 3 which is firmly connected to an opening lever 1.
  • the opening lever 1 is pivotally mounted about an opening lever bearing pin 16 which is fixed to the housing.
  • one spring leg of a leg spring 15 rests on the latching bolt 3 under spring load and presses it into a recess 34 which is embedded in a side shoulder in the pivot lever 2.
  • the recess 34 mentioned serves to fix the closed position of the ski binding, so that the locking pin 3 is in locking engagement with the recess 34.
  • the other leg of the leg spring 15 is supported on a surface fixed to the housing.
  • This leg spring forms a spring load for the opening lever 1 in order to keep it spring-loaded in its closed position.
  • leg spring 17 which is supported with one leg end on the inside of the pivot lever 2 and with its other leg end rests on a surface fixed to the housing. This leg spring 17 ensures that when the binding is open, the pivot lever 2 is held in its open position, the locking bolt 3 being in the region of a recess 35 in the open position. This prevents a transition to the closed position unintentionally when the binding is open, i.e. the pivot lever 2 is held in the open position by the leg spring 17.
  • the locking pin 3 is connected over the entire width of the locking and release device 22 to the opening lever 1 connecting the two release parts, so that this ensures that the locking connection assigned to the other wire cable 12, which is otherwise of the same design, as shown in Figure 8 with respect to the wire rope 12a, triggers and now trigger the two wire ropes synchronously in the arrow directions 51.
  • the locking bolt 3 which extends over the entire width of the device, disengages from the locking recess 34, which is assigned, for example, to the upper part of the locking and triggering device 22, also simultaneously triggers the other locking, for example, assigned to the wire cable 12.
  • the adjusting screw 8 can be adjusted with a hexagon 31 arranged at the rear end.
  • FIGS. 9 to 15 show the individual triggering processes once again in chronological order in order to clarify the previously described triggering process even better.
  • the locking pin 3 now overcomes a shoulder 54 in the Transition area between the latching recess 34 and the latching recesses 35 and, according to FIGS. 13, 14 and 15, reaches the area of the latching recess 35 assigned to the open position.
  • the pivot lever 2 now begins to pivot in the direction of the arrow 55 in the direction of the arrow 55, so that the locking pin 3 comes completely into the region of the locking recess 35 assigned to the open position.
  • the locking pin 3 is secured in the locking recess 35 and cannot inadvertently return to the closed position in the region of the locking recess 34.
  • a housing enclosing the entire device is provided, the upper surface of the housing being designed as a plastic film, through which the opening lever 1 and the Can operate swivel lever 2.
  • the characteristic of a membrane keyboard is thus achieved, whereby the pivoting movements of parts 1 and 2 can be achieved through the membrane with the housing closed.
  • the binding is essentially formed by a locking ring 23 which has locking recesses 36 arranged uniformly distributed on the circumference.
  • each locking bolt 29 engages in these locking recesses and are displaceably mounted in a retaining ring 27 which surrounds the locking ring radially on the outside. At its rear end, each locking bolt 29 has an adjusting screw 37 with which the locking engagement of each locking bolt into the associated locking recess 36 can be set individually.
  • the free, pivotable part of a lever 38 bears against the rear end of the locking bolt 29 and is pivotally mounted about an axis 39 in the region of a rotatably mounted clamping ring 48.
  • the other end of the lever 38 is provided with an elongated hole 42 through which a bolt 43 engages, which is part of a bell crank 40.
  • the elongated hole is arranged in the bell crank 40.
  • the bell crank 40 is triangular in shape and is connected to the retaining ring 27 so as to be rotatable about an axis 41.
  • the deflection lever 40 carries at a distance from the aforementioned bolt 43 and from the axis 41 a further bolt 44 which pivotally receives one end of a lever 45, the other end of which is pivotably mounted in an axis 46 in the clamping ring 48.
  • the lever transmission described from the locking pin 29 to the rotatably mounted clamping ring 48 has the purpose of translating the relatively small displacement path of the locking pin 29 into a relatively large displacement (direction of rotation) of the clamping ring 48.
  • the lever device mentioned thus offers the essential advantage that a reliable operation is achieved.
  • the design of the deflection lever 40 as a triangular link thus results in the linkage being stretched during the transition from FIG. 16 to FIG. 18, so that the entire clamping ring 48 in the direction of the arrow 49 by a relatively large displacement path of e.g. Is moved 7 mm. This results in a leverage ratio of approximately 1: 3 with respect to the displacement of the locking pin compared to the displacement of the clamping ring 48.
  • the cable 12 is thus also moved by approximately 7 mm and this results in a reliable control of the locking and triggering device 22 mentioned and described above.
  • the respective cable (wire rope 12, 12a) is in this case pivotally fastened in a holder 50 to the tension ring 48.
