Definitions

  • the centreof the ski serving as the reference point is actually defined for an average size boot (for example, size 40,5 for a 2 m ski).
  • an average size boot for example, size 40,5 for a 2 m ski.
  • skis rented to the first customer would be suitable for a special slalom event, while the second customer could use them only for downhill skiing.
  • the present invention is concerned with ascertaining from a reference position corresponding to a standard boot size, the correct location of the safety bindings on a ski, in order to adapt the bindings to the size of boot worn by the skier. Moreover, this is achieved without altering the characteristics of the pair of skis.
  • the process according to the present invention consists in: making the front and rear jaws mobile in the longitudinal axis of the ski; mechanically connecting the jaws in a manner such that moving one jaw in one direction causes the otherjaw to move in the other direction; and in acting upon the mechanical connection between the jaws to displace them simultaneously in a single operation, until the jaws are located in a position such that the sole of the boot may be clamped and held to the ski.
  • the jaws may, of course, move at the same speed under the action of the mechanical connection, but in one preferred form of embodiment these movements take place at different speeds in relation to the ski. It is preferable that the heel piece move at a lower speed than the toe stop.
  • the device according to this invention makes it possible to maintain the axis of the skiers leg at all times in the same location in relation to the ski, if the ratio between the respective speeds of movement of the jaws is made equal to the ratio between the distances be tween the axis of the leg and the front and rear ends of the sole.
  • the axis of the leg will at all times be at the same location in relation to the ski, regardless of the size of the boot worn by the skier.
  • the present device for carrying the above process is one in which the jaw components slide in a fixed structure comprising a means for longitudinal guidance. the jaws being connected to each other by a mechanism which derives them in opposite directions along the longitudinal axis of the ski, the mechanism having a single control.
  • speedreduction means co-operating with at least one of the jaws provided.
  • FIG. 1 is a schematic illustration in perspective of a device according to the invention having a rackandpinion drive particularly suitable for adjusting the safety bindings mounted on the ski;
  • FIG. la illustrates a device identical with that shown in FIG. 1 but adapted more particularly to drilling the holes for assembling the binding to the ski;
  • FIG. 2 is a view similar to those in FIG. 1 and la, in which the drive consists of a system of cables;
  • FIG. 3 is a view similar to those in FIGS. 1, 1a and 2 in which the drive system for the retaining elements is a screw.
  • FIGS. 1 and la show an example of each of the possible adaptations, whereas, for the sake of simplicity, FIGS. 2 and 3 show only that part of the device which remains identical regardless of the use to which it is put.
  • the numeral 1 indicates the central portion of a ski, to which is attached, by means of screws for example, a base plate 2 enclosed in a housing 3 attached to plate 2 by any suitable means (screwing, crimping, welding, etc.).
  • Housing 3 has a longitudinal slot 4 located along the axis of the ski, in which are lo cated a front stop 5 and a heel piece 6. These will not be described in detail since they are conventional safety bindings.
  • the front stop has a downward extension 7 which passes into the housing and is integral with a primary rack 8 running practically along the entire length of the housing and adapted to protrude therefrom through windows 9 arranged in the ends thereof.
  • rack 8 engages with a control pinion l integral with a vertical shaft 11 rotatably mounted both in base plate 2 and in the upper housing 3.
  • Shaft 11 serves to set the device to the size of boot, and may with advantage be equipped with a knob 11 carrying reference marks 12 making it possible to adjust the binding as a function of the size of boot worn by the skier.
  • Pinions l3, 14 are integral with pinions 16, 17 of reduced diameter engaging with the toothed branches 18, 19 of a secondary rack 20 integral with base 21 of heel piece 6 which extends across slot 4 in the housing.
  • front stop may carry a pointer 22 moving along a scale 23 indicating the length of the ski.
  • base plate 2 also has an opening which exposes the mark.
  • the distance between the toe stop and the heel piece must be equal to the standard boot size, i.e. 40.5 for a ski 2.5 m in length; in this case, pointer 22 on the stop points to the mark on the scale corresponding to the length of the ski used.
  • means may be provided to lock knob 11 to the housing. Any known arrangement may be used for this purpose, forexample a spring finger 25 engaging in one of a series of holes in the surface of the housing.
  • FIG. la illustrates the case in which the device according to the invention is used to determine the location of the holes used to assemble the safety-binding system permanently to the ski, and also to drill the said holes.
  • baseplate 2A (in the form of a frame exposing the central part of the ski), which is integral with housing 3a, is placed on ski 1a in a manner such that it may be moved longitudinally in order to find the centre of the ski through opening 24a;
  • stop 5 and heel piece 6 in FIG. 1 are replaced by drilling templets G and G respectively having jaws 5a and 6a between which the boot is accommodated.
  • templet G is integral with primary rack 8a
  • templet G is integral with secondary rack 20a.
  • Jaws 5a and 6a are also integral with horizontal plates P P equipped with drill jigs C (four in plate P three in plate P in the example illustrated) to guide the drills which drill into the ski the holes into which are inserted the screws permanently assembling the conventional toe stop and heel piece to the ski.
  • any mechanical parts between the drill jigs and the ski will have appropriate openings below the jigs, as shown at f, in rack and at f in housing 3a.
  • each drilling templet is equipped with a clamping mechanism, indicated in a general manner by S, which will be described only briefly since it is a known device which is not a part of the invention.
  • Each of the clamping mechanisms has two lateral ears 0 extending vertically on each side of the ski; ach ear 0 is integral with a head T, the flat bottom surface of which slides on plate P (or P Heads T have internal threads of the same pitch but opposite hand and are aligned by means of a fixed central dowel B integral with plate P, (or P A screw V passes through heads T and dowel B, the screw being prevented by the dowel from moving axially, but being free to rotate under the action of a knob U.
  • the parts of the screw engaging with heads T have left and right-hand threads, so that rotation of knob U causes heads T to move simultaneously towards or away from dowel B. It will be understood that when heads T move towards each other, ears 0 clamp the device to the ski and lock the drilling templets in position.
  • FIG. la has numerous advantages making the operation of drilling the skis simpler, faster, safer, and more accurate.
  • the drilling device is pre-set to a reference boot-size (for example 40.5), the following procedure is all that is required to drill the skis for another size, for example 44;
  • FIG. 2 illustrates an arrangement similar to that in FIGS. 1 and la, except that the rack and pinion is replaced by a system of cables.
  • FIG. 2 (like FIG. 3) shows only those parts of the jaw structure such as are required in order to understand the invention, it being understood that the system may be applied, as has been seen in connection with FIGS. 1 and 2, both in conjunction with drilling templets and when safety bindings are directly available.
  • Hooked to the front face of front jaw 5 is a cable 26 which winds around shaft 27 of the size-setting knob, to which one end of cable 26 is attached.
  • Located behind rear jaw 6 are two pairs of pulleys 28, 29, each consisting of a large-diameter pulley 30, 31 and a smaller diameter pulley 32, 33, the pulleys being integral with common vertical axes 34, 35.
  • Attached to large pulleys 30, 31 are the ends of cables 36, 37 which pass around the pulleys and unite at 38 with the end of an axial cable 39, the opposite end of which is attached at 40 to the rear face ofjaw 5.
  • a spring 43 is preferably hooked between the front and rear jaws and urged these two elements towards each other. It is, of course, quite conceivable that the rear jaw could be pushed or pulled towards the front jaw by means of a spring, or any other resilient system, arranged differently from spring 43 but performing the same function.
  • the mechanical sizesetting system consists of a rod 46 running inside the housing along the longitudinal axis of the ski, the rod being mounted in the housing in a manner such that it is free to rotate therein but cannot move axially.
  • the forward end of the rod is mounted in a stationary bearing 47 integral with the housing and in an intermediate bearing 48 integral with baseplate 2.
  • Bearings 47 and 48 are of a conventional type which allows the rod to rotate without moving axially.
  • Rear end 49 of the rod protrudes from housing 3 and carries an adjusting knob 50.
  • the rod also has two threaded zones 51, 52 running respectively between bearings 47 and 48 and between bearings 48 and knob 50.
  • Threads 51, 52 are of opposite hand, for instance thread 51 may be right-handed and thread 52 left-handed.
  • Thread 51 co-operates with a threaded hole in the structure of front jaw 5, while thread 52 engages with a threaded hole in the structure of rear jaw 6.
  • the pitch of thread 51 is three times that of thread 52.
  • a templet device for drilling a ski in order to locate along the longitudinal axis of the ski the positions for securing to the ski, front and rear parts of a safety ski binding relative to a reference position carried by the ski and corresponding to a standard ski boot, whatever the size of the ski boot, said device comprising:
