Definitions

  • the present invention relates to an apparatus for adjusting a ski safety binding, comprising a support for skiing, an artificial foot intended to be introduced and fixed in a shoe mounted in the binding and comprising an upright, a device for application of forces acting on the upright of the foot, and a device for measuring forces.
  • an apparatus which also comprises an artificial foot intended to be rigidly fixed to the shoe.
  • This foot is rigidly coupled to a force application device which comprises an elastically deformable transmission member and provided with one or more strain gauges.
  • the latter are connected to circuits such as measurement units, making it possible to control the forces applied to the artificial foot and therefore to the shoe.
  • the object of the invention is therefore to provide a device of the kind mentioned at the start which is compact and of practical use, while making it possible to carry out checks giving precise, reliable and complete results. It is based on the design of an apparatus, the force application device of which is of the versatile manual type and the measurement device of which can be easily switched over to supply the results of successive measurements in different modes of force application.
  • the adjustment device of the present invention of the kind mentioned at the start is characterized in that it comprises on the one hand an elongated force transmission element capable of undergoing elastic deformations as a function of the forces transmitted, having one end integral with the upright and one end shaped as a coupling member, and on the other hand means for measuring said deformations switchable as a function of a mode of stress freely chosen from several different modes, and in that the device d application of forces includes means capable of causing forces to act on said coupling member so selective according to said different modes of solicitation.
  • Fig. 1 shows the elements which compete to facilitate the implementation of the device and ensure the accuracy of the measurements.
  • the ski 1 is fixed to the support (23) in a horizontal position by means which will be described later.
  • a shoe 3 into which an artificial foot 4 is introduced, which itself comprises an amount rigid 4a and a telescopic base 4b, articulated at the lower end of the upright 4a, the articulation and the front end of the base 4b being provided with rollers 5, so that the artificial foot adjusts precisely to the 'interior space of the shoe 3.
  • the upright 4 At its upper end the upright 4 has a connecting segment 6, with a hooking rod 7 which projects rearwardly.
  • a strap 8, comprising at its lower part a loop 8a and at its upper part a metal strip 8b provided with holes 9, fits under the heel of the shoe 3 and can be stretched to engage one of the holes 9 on the pin 7
  • the foot 4 is thus absolutely integral with the shoe 3.
  • a measuring block which includes a force transmission bar 10.
  • This essential element of the construction described is a segment of a metal bar, preferably of steel, of cylindrical shape, perfectly homogeneous, machined so to undergo regular elastic deformations when applying forces.
  • This cylindrical bar is fixed, for example by welding, through the element 6 and extends vertically upwards. At its upper end, it comprises a connecting element of square or rectangular section 10a.
  • a locking device 11 for example of the type comprising a button actuating a rod inserted in the connector 10a, provided with a lug and retained by a spring.
  • a force application bar 12 of rectilinear appearance, comprises, in the middle of its length, a first coupling element 13 having the shape of a square or rectangular tube segment adjusted to the dimensions of the connecting element 10a.
  • This tube segment extends perpendicular to the bar 12.
  • a similar segment 32 also extends at one end of the bar 12, in its extension by forming a second coupling element of this bar to the transmission element 10
  • Each of the tube segments 13 and 32 comprises, on one side, a hole 14 and, on the other side, a slot in the form of a key entry 14a, these means being capable of cooperating with the locking device 11 to allow easy connection of the coupling element 13 or 32 to the connector segment 10a. This locking prevents the shoe from escaping after the binding is released.
  • a strain gauge 15 which is bonded against the cylindrical face of the transmission rod 10.
  • a corresponding gauge 22 is bonded in a position diametrically opposite to the gauge 15 and these two gauges 15 and 22 are connected by conductors 16 and 17 to a measuring device 18 which is housed in a box the upper face of which comprises, on the one hand, a display area 19 and, on the other hand, a keyboard 20.
  • the device is further provided with a printer and means for producing a strip of paper 21 with indications confirming the results of the measurements.
  • Figs. 2, 3 and 4 illustrate the arrangement and the possible connections of the strain gauge 15 and of the counter gauge 22.
  • These gauges are glued in symmetrical positions against the cylindrical face of the transmission rod 10 and, as seen in fig. 3, they together comprise four resistors A, B, C, D which, in each gauge, are inclined at 45 ° in opposite directions.
  • These resistors are connected by connections 16 and 17 to measuring circuit placed in the housing 18, so as to be able to be connected in different ways, the switching being effected by manually controlled contacts, as will be seen below.
  • FIG. 4 shows how the resistors A, B, CD are arranged in the measurement circuit and what deformations they undergo when the bar 10 is subjected, on the one hand, to a torsional force around its axis and, on the other hand, to a bending force in a direction perpendicular to the diametral plane passing through the centers of the gauges 15 and 22.
  • a torsional force according to the arrow T in FIG. 2, the resistors A and C undergo an elongation and the resistors B and D a contraction.
  • Resistors A and D will therefore be connected in series as well as resistors B and C and the voltage variations of these two chains will be compared.
  • Figs. 5, 6 and 7 show how these two modes of applying force are implemented.
  • the ski 1 is fixed to a support in a horizontal position, so that the force transmission bar 10 rises vertically above it.
  • the bar 12 is connected to the coupling segment 10a, as seen in FIG. 1, that is to say by means of its coupling element 13 located in the middle of its length, so that one can, by hand or using a jack, exercise on the bar 12 a sufficient torsional force to ensure the triggering of the binding 2.
  • the ski is fixed to the rigid support 23 by a fixing mechanism which comprises a rear link member 24 and a front link member 25.
  • the front link member 25 is shown in detail in FIG. 7.
  • the connecting member 24 has a constitution quite similar to that of the member 25 but, instead of having, at its rear edge, a hooking member in the form of an inverted U, the plate of the member 24 is mounted on a bearing which pivots on a fixed pin, integral with the support 23 and oriented horizontally perpendicular to the direction of the ski in FIG. 5.
  • the connecting member 25 can be hooked to an angle iron 29, fixed to the support 23, at the same height as the pivoting connecting member 24.
  • the bar of force transmission 10 is directed upwards in a slightly inclined position and the bar 12 is linked to the coupling segment 10a by its coupling element 32, located at one of its ends.
  • the bar 10 In this position, as seen in fig. 6, it is possible to exert on the bar 10, the bending force which simulates the fall forward and must cause the release of the binding for a threshold value such that the skier retains his bodily integrity.
  • the apparatus described makes it possible to carry out an effective and rational adjustment of each safety fastener according to objective standards.
  • standards corresponding to the efforts that the legs of a skier can undergo, in cases of maximum stress such as, for example, a torsional effort or a bending effort corresponding to a fall forward or also falling back.
  • These limit values were established on the basis of complex personal data, such as sex, height, weight, age and, in some cases, the dimensions of the tibia in diameter or possibly other characteristics.
  • the measurement circuit provided in the housing 18 includes a memory and a processor capable of developing the values of the standards as a function of data introduced into the circuit.
  • This processor also compares the values of the standards with the measurement results and ensures the receipt of the result.
  • a display area 19 which is not only equipped with a series of display positions 33, representing numbers and giving the values of the couples, but also various figurines 34 facilitating the progress of the data introduction and measurement program. It is not necessary here to give in detail the meaning and function of all the figurines.
  • 34a and 34b figurines connected to contacts and giving the order to introduce the indication of the sex of the skier in 34c a figurine enjoining the introduction of its height, in 34d figurines enjoining the introduction of the age, etc.
  • the circuit includes a program which controls the flashing of these various figurines as a call signal for the introduction of the corresponding data, the excitation of the various figurines occurring successively in the order in which the program must run and being interrupted when the corresponding data has been entered.
  • the arrows 35a and 35b are in connection with control contacts ensuring the switching of the strain gauges 15 and 22 according to the mode of application of forces which will be produced.
  • the apparatus described makes it possible to test a safety binding and to correct its adjustment under conditions that are both simple and precise while being of minimum bulk. Thanks in particular to the fact that the force application device comprises the bar 10, which is rigidly fixed to the upper end of the foot 4 and which is equipped with gauges 15 and 22, various modes of application can be implemented successively under conditions of good reliability, since the same gauges ensure the measurement in the different cases.
