Definitions

  • the invention relates to a ratchet buckle for closing a shoe according to the preamble of the main claim, in particular for a ski boot.
  • ratchet buckles For closing snowboard shoes, various ratchet buckles are known, which are described, for example, in DE 101 05 523 A1, DE 198 00 148 C2 and EP 1 221 291 A1. These known ratchet buckles have a plastic existing drawstring with a toothing, in which an external toothing of a draw roller engages, wherein the draw roller can be rotated by a clamping lever to tension the drawstring.
  • the clamping lever and the tension roller are in this case integrally formed, so that a pivoting of the clamping lever by a predetermined angle to a corresponding rotation of the
  • Pull roller leads to the same angle.
  • a disadvantage of these known ratchet buckles is the fact that high tensile stresses can be realized in the drawstring only with a large operating force.
  • the known ratchet buckles described above are therefore only suitable for snowboard bindings in which no great tensile stresses are required to close the snowboard binding. For ski boots, however, much greater tension is required to close the boot to achieve a tight fit.
  • fasteners are used, as described for example in EP 0 657 117 Al, EP 1 205 122 A2, EP 1 279 345 A1 or EP 0 140 874 A1.
  • These tension locks also a clamping lever is provided, which, however, does not tension a tension band, but a pre-set tension member. The tension is thus pre-adjusted before the actual closing process by an adjustment of the tension member and can then no longer be adjusted in the actual closing operation.
  • the invention is therefore an object of the invention to provide a ratchet buckle, which is also well suited for closing ski boots.
  • the invention is based on the technical knowledge that the above-described conventional ratchet buckles are therefore not well suited for ski boots, because the Spannhe- and the tension roller are integrally formed. This has the consequence that a rotation of the clamping lever by a predetermined angle to a corresponding rotation of the draw roller leads by the same angle, so that the torque transmission from the clamping lever on the draw roller and thus on the drawstring is done without a translation, resulting in a large operating force required.
  • the invention therefore encompasses the general technical teaching of connecting the tension lever to the tension roller via a gear, the gearbox having a predetermined gear ratio, as a result of which the required operating force for actuating the tensioning lever is reduced.
  • the use of a transmission between the tensioning lever and the draw roller offers the advantage that the large tensile stresses required when closing ski boots can be realized with a relatively small operating force for actuating the tensioning lever.
  • the transmission between the tensioning lever and the tensioning roller has at least one gear which is secured against rotation with the tensioning roller and in which the tensioning lever engages in order to rotate the tensioning roller. It is important that the gear has a larger diameter than the draw roller to achieve the desired gear ratio.
  • a gear is mounted on both end sides of the draw roller, so that the clamping lever engages on both sides in the two gears to rotate the draw roller.
  • the invention is not limited to specific values. Preferably, however, the transmission ratio is greater than 1.5, 2 or 3. This means that the torque applied by the operator to the tensioning lever is correspondingly smaller than the torque acting on the tensioning roller.
  • the tensioning lever and the tensioning roller in the ratchet buckle according to the invention are preferably designed as separate components, which allows the intermediate gear of the transmission.
  • the tension roller is displaceable within the ratchet buckle in order to enable the tension roller to be turned back after a tensioning movement by the tension roller being briefly lifted off the tension band.
  • the draw roller preferably has an axis of rotation which is stationary within the ratchet buckle. This is possible because the clamping lever and the tension roller are formed as separate components and thus can be mechanically decoupled.
  • the ratchet buckle according to the invention has a ratchet which mechanically connects the tensioning lever to the tensioning roller, the ratchet engaging the tensioning roller or the associated toothed wheels only in a pivoting direction of the clamping lever entrains and otherwise mechanically decoupled the clamping lever of tension roller or the associated gears.
  • the tensioning lever and the tension roller in the known ratchet buckles for snowboard bindings described above are integrally formed as a component and therefore can not be decoupled from each other, so that the ratchet function must be implemented in the conventional ratchet buckles described above in a different way.
  • the ratchet buckle according to the invention preferably has a releasable locking mechanism which selectively couples the tensioning lever with the tension roller or the gears connected thereto or decouples from the tension roller or the gears.
  • the locking or unlocking of the locking mechanism can in this case, for example by Operating elements (eg buttons or push buttons) take place, which can be attached to the tensioning lever, for example.
  • the ratchet buckle according to the invention preferably has a releasable pawl which prevents the tension band from slipping out of the ratchet buckle in the tensioned state.
  • the pawl engages in the draw roller or the gears and thereby locks them, wherein the draw roller in turn fixes the drawstring.
  • the pawl thus acts indirectly via the gears or the tension roller on the tension band.
  • the pawl engages directly into the tension band and thereby prevents slipping out of the tension band in the tensioned state.
  • the tensioning lever In the tensioned state, the tensioning lever can preferably be folded against the shoe to prevent the user from being disturbed by a protruding tensioning lever. It is possible that the clamping lever automatically locks the pawl in the folded state, thereby preventing release of the pawl.
  • the clamping lever For this purpose, for example, be arranged in the clamping lever, a recess which receives the pawl or an associated actuating element in the folded state and thereby blocked.
  • the tension roller on its lateral surface on an external toothing, in which engages a corresponding toothing of the tension band.
  • the coupling between the draw roller and the drawstring can thus be done positively.
  • the tension band is wound onto the tension roller, so that the tension roller in this variant preferably has a smooth lateral surface.
  • the drawstring is then preferably bendable to allow winding onto the draw roll.
  • tension band used in the context of the invention is to be understood generally and is not restricted to bands in the narrower sense, in which the width is substantially greater than the thickness. Rather, the drawstring can also be a rope, a wire or the like.
  • the invention is not limited to a ratchet buckle as a single component, but also includes a shoe with such a ratchet buckle according to the invention, for example, a ski boot, a snowboard boot, a snowboard binding, a skate, a roller skate or a mountain boot can act.
  • a shoe with such a ratchet buckle according to the invention for example, a ski boot, a snowboard boot, a snowboard binding, a skate, a roller skate or a mountain boot can act.
