Definitions

  • the present invention relates to a ski binding for use in racing and cross country skiing. More specifically the invention relates to a ski binding with a keeper means and means for pulling a ski boot into said keeper means and to retain it therein by means of a clamping device wherein said pulling means comprises a generally U-shaped fixing wire arranged in guides on said keeper means, its free ends extending upwardly to be coactable with holes in the front sole portion of the boot, and wherein the transverse portion of the generally U-shaped fixing wire is engagable with said clamping device, so that the free ends of the wire upon depression of a tensioning arm of said clamping device pull the ski boot forwardly into the keeper means of the binding.
  • said pulling means comprises a generally U-shaped fixing wire arranged in guides on said keeper means, its free ends extending upwardly to be coactable with holes in the front sole portion of the boot, and wherein the transverse portion of the generally U-shaped fixing wire is engagable with said clamping device, so that the free ends of the
  • Norwegian Patent 78.181 relates to a ski binding intended for slalom and down hill racing with means for releasable blocking of the swing action of the boot heel up from the ski by means of a rigid, possibly somewhat resilient arm or plate extending in a rearward direction relative to the keeper means and intended to enter into a channel, an indentation or the like in the heel portion of the boot for thereby to cause locking of the heel to the ski.
  • the said arm or plate is formed by an extension of the bottom plate of the keeper means or is fixedly attached to the keeper means or the upper face of the ski.
  • Norwegian Patent 47.051 relates to a ski binding without any rear strap, comprising tabs known per se with inwardly directed projections bearing against the upper edge of the sole.
  • a plate known per se and shiftable in the direction of the ski has on its upper face suitable means (e.g. spikes) which can be brought in engagement with the lower side of the sole, blocking devices being arranged to prevent the plate when moved in between said tabs to be pulled out again, so that the boot when arranged on the plate and moved therewith in between, said tabs will be firmly locked to the ski in coaction with said devices on the upper side of the shiftable plate, the blocking device and said inwardly bent projections on said tabs.
  • the boot is moved in the longitudinal direction of the ski during the clamping process.
  • the clamping itself is provided by means of a resilient plate upon which a knob is placed being coactable with holes in said plate. If the boot should be of a form to most suitably be clamped by hole number two of the holes, it may so happen that this is not possible and that clamping therefore must take place by the first hole, whereby the risk is that the boot will not fit properly in the binding. The solution is therefore not particularly advantageous in practice.
  • Norwegian Patent 63.959 relates to a binding consisting of two separate and on- screwable parts, one part consisting of a clamping device with an adjustable intermediate piece and where a rear strap loop is intended to grip about the heel of the boot.
  • Norwegian Patent 84.786 relates to a pretensioner for a ski binding where a tensioning device fixed to the ski is connected with the front end of a helical spring, the other end of which for regulation purposes is in thread engagement with a screw spindle connected to the rear strap.
  • the screw spindle extends through the means supporting the front portion of the straps, and on the rear side thereof is provided with a service button for regulation of the connection and the tensioning is transferred to the rear strap. It is here the case of two separate main parts.
  • Swiss patent 299.398 refers to a ski binding in accordance with the preamble of claim 1 into which the ski boot is pulled by a spring connected at one end to a torque arm, there being a hook directed upwards at the other end intended for engagement with a corresponding hold at the underside and front section of the boot sole. To obtain the required side stability it is important, however, to fix the boot at the rear edge thereof and to this end said patent discloses a hold for obtaining this.
  • the present invention has an object to provide a ski binding which overcomes the many disadvantages of the known bindings and which is simple and cheap to manufacture and advantageous upon installation on the ski.
  • the ski binding according to the invention is characterized in that the clamping device comprises an intermediate piece into one end of which said transverse portion of the fixing wire may be snapped and the other end of which is hinged to a middle portion of the tensioning arm, one end of which tensioning arm is hinge-connected to a front portion of the said keeper means and the other end of which upon depression causes forward pushing of the fixing wire via the intermediate piece, and in that a forward end portion of the intermediate piece is shaped to form contact face for an acting means, e.g. a ski pole pin, the binding being releasable by further depression of said forward end portion.
  • an acting means e.g. a ski pole pin
  • the intermediate piece may be adjustable in length by letting it consist of two parts, one being in the form of a screw and the other being internally threaded.
  • the fixing wire compasses substantially most of the clamping device.
  • the binding has a keeper means 1 known per se for the front sole portion of the ski boot.
  • the ski boot is provided with grooves or recesses 3 providing free passage for a movable, substantially U-shaped wire 2, e.g. a metal wire, with upwardly protruding end portions 4 co- acatable with holes in the front sole portion of the boot, which holes may be arranged in accordance with accepted standards.
  • the wire 2 is freely movable in the longitudinal direction of the ski and may thereby together with the boot be pulled forwardly and into the binding.
  • the advantage of using a wire with the said configuration is based both on productional reasons and use. As regards production the number of parts are reduced because the upwardly projecting end portions coact with the boot.
  • the advantage in use is the free movement of the wire in the spacy grooves or recesses 3.
  • the movability of the wire is not barred by collection of snow or formation of ice, a problem that may be encountered with some of the known solutions.
  • the binding has a tensioning mechanism 7, 8 consisting of a tensioning arm 7 and an intermediate piece 8.
  • the tensioning arm is hinge-connected 5 to the keeper means 1 and the intermediate piece 8 is at one end hinged 6 to substantially a middle portion of the tensioning arm 7 and at its other end snapped onto the transverse portion 9 of the wire 2.
  • the upwardiy extending ends 4 of the wire will be pulled into the keeper means 1 together with the boot.
  • the hinge 6 forms a dead point so that the movement of the tensioning device in said position is locked.
  • the reference numerals 13 indicate holes for attaching the binding to the ski by means of screws (not shown). Three holes will normally be sufficient for the installation.
  • the intermediate piece 8 is provided with a longitudinal hole for introduction of a threaded bolt 10 adapted to be hinge-connected 6 to the middle portion of the tensioning arm.
  • the bolt itself may provide the necessary internal threads in the intermediate piece, and expensive tools for casting the required threads or making threads through machining are unnecessary.
  • it may still be suitable to make the length adjustable piece from e.g. brass or other suitable metal.
  • a construction with a clamping mechanism being locked through a dead point is known, but since this function is acting conversely, so that the wire in a new manner lies around the structure, the components will be subjected to compression instead of tensioning.
  • the keeper means 1 and the tensioning arm 7 are preferably made from a suitable plastic material.
  • the intermediate piece 8 with its integral end piece 12 may be made from e.g. reinforced plastic material or a metal.
