Definitions

  • the present invention relates to a device for regulating an elastic system in a safety fixing device for ski boots, of the kind provided with an indicator showing the adjustment settingof the device, said device comprising: a fixing body mounted on said ski and provided with a jaw for retaining the ski boot in position; elastic means for locking-said fixing device in a definite position with respect to the ski, said locking means being housed in said fixing device body and ensuring the retention of the boot on the ski; means for regulating the retention force of said elastic locking means by modifying the length of said elastic means, said regulating means being also housed inside the body of said fixing device; means for indicating the modification of length of said elastic locking means which is rigidly fixed, for movement in the direction of the length of said locking means, to said regulating means; and visualization means for said indicator means; said visualization means being rigidly fixed to the fixing device body and being located in the zone of displacement of said indicator means.
  • the present invention relates to a device for regulating an elastic system which is provided with an indicator showing the value of the regulation of the device.
  • the device according to the invention is. especially adaptable to safety fixing devices for skis.
  • these fixing devices comprise an elastic member holding a jaw in the closed position and releaseable in the event of the use of excessive forces applied to the limbs of the skier.
  • the force applied by the elastic member on the jaw may be adjusted to a pre-determined value as a function of various parameters and especially of the diverence of the skier and the type of run carried out.
  • the skier when once this adjustment has been made, the skier must be able to check at any moment that it has been modified by the stresses which may be undergone by the elastic member during the travel of the skier.
  • Fixing devices are already known comprising such adjustment indicators, which are generally formed in a very simple manner by a pointer movable in front of a graduated scale, the'index being associated with the elastic member, of which it follows the variations of condition.
  • a system of this kind has certain disadvantages, the most outstanding of which resides in the fact that it is difficult to read.
  • the fixing devices are made as small in size as possible, and it is obvious that the skier when travelling does not have available any optical or other means for evaluating slight modifications of the value of the adjustment.
  • the screw serving to regulate the spring carries at least one member which drives, at every turn of the screw, a toothed wheel carrying the indicator.
  • the present invention proposes to produce a regulating device for an elastic system provided with an adjustment indicator, the construction of which is simple and inexpensive, and does not lead to any increase in the overall size of the fixing device.
  • the device according to the invention makes it possible to increase readability by the user of the adjustment value shown on the indicator, this being permitted by the fact that the movement of the pointer is larger than the travel of the elastic system, or is at least equal to this travel when the latter has a sufficiently larger value.
  • the fixing device comprises:
  • a fixing body mounted on the ski and provided with a jaw for holding the boot in position
  • an elastic locking means for the fixing device in a predetermined position with respect to the ski the said locking means being housed in the fixing body and ensuring the holding of the boot in position on the ski;
  • the said visualizing means being ridigly fixed to the fixing device body and located in the zone of movement of the indicator means.
  • the arrangement of these devices is such that by the single actuation of the regulating means there is produced a movement of the indicator proportional or at least equal to the modification in the length of the elastic member.
  • the regulating screw comprises two portions threaded with opposite pitches and two parts movable in translation engaged respectively on one of the portions, while two springs subjected respectively to the action of the moving parts and extending between a common reaction member and the moving part with which each of them is associated.
  • the regulating indicator is preferably constituted by two blades which overlap in the central zone of the device, each of these blades being carried by one of the moving parts with which it moves. The two blades thus move in opposite directions, and the modification of length of the elastic system is equal to the sum of the movements of the blades.
  • this type of device may be employed more particularly in the case of front abutments.
  • the regulating screw is made in such manner that, in addition to a threaded rod in engagement with the screwed portion of the moving part, it has a coaxial ring provided with a thread and which is engaged in a corresponding threaded portion of the fixed body.
  • the coaxial ring constitutes the regulating indicator with the body of the fixing device.
  • the threaded portions of the threaded rod and the ring have the same direction and are preferably of different pitches.
  • the pitch of the ring will advantageously be greater than the pitch of the threaded rod, and the modification of length of the spring will therefore be equal to the difference between the pitches of the ring and the threaded rod.
  • FIG. 1 is a general view in transverse section with re spect to the axis of the ski, ofa front abutment comprising the device according to the invention
  • FIG. 2 is a diagrammatic view of the system of FIG. 1 showing two extreme positions of adjustment of the elastic system
  • FIG. 3 shows an axial section of the extremity of a heel fitting comprising a second form of construction of the device according to the invention, placed in an extreme position of adjustment, and
  • FIG. 4 shows the device of FIG. 3 in another position of adjustment.
  • FIG. I there has been shown at l, a ski on which is mounted a base-plate l' of the fixing device 3 which pivots about a vertical pivot 2 rigidly fixed on the said plate.
  • the fixing device 3 which will not be described in detail, may be of the same type as the abutment forming the subject of U.S. Pat. No. 3.455.570 filed on Oct. 24, 1967; this abutment carries in known manner a jaw M (see FIG. 2) which co-operates with the sole of the boot.
  • the fixing device is held in the axis of the ski by a conventional system indicated generally at 4, which permits the safety release of the fixing device and its automatic return to its normal position on the ski.
  • a conventional system indicated generally at 4
  • This elastic system is known, it will not be described in detail.
  • the threaded zones 6 and 7 have identical but oppositely-threaded zones so as to permit the simultaneous moving together or moving apart by the same amplitude of the moving parts 8 and 9 with respect to the vertical axis XX' of the fixing device.
  • the screw 5 passes freely through a reaction member 10 fixed to the base-plate l and serving as a support for cups l1 and 12 surrounding the screw 5 and in which are housed the extremities of two springs, 13 and 14, arranged in series. The most distant extremities of the springs 13 and 14 are supported against the moving parts 8 and 9.
  • the indicator device is constituted in the example shown by two blades 16 and 17 extending the cups l8 and 19, which are fixed by any known means to the moving parts 8 and 9 respectively, and which thus move together with these latter.
  • the blades 16 and 17 overlap in the sone of the axis XX' of the fixing device underneath a reading window 20 formed in the upper face of the fixing device body and preferably As can more particularly be seen from FIG. 2, the
  • blade 16 will advantageously carry a numbered scale in front of which there will move the extremity 22 of the blade 17, which may possibly be coloured in order to provide clearer reading.
  • the blade 16 will be transparent in order that the edge of the blade 17 can be seen underneath it.
  • FIG. 2 shows the two extreme positions of adjustment of the device.
  • all the graduation not covered by the coloured pointer is continuously visible, and the value of the adjustment is given by the largest figure which comprises opposite the pointer.
  • the figure representing the value of the adjustment should appear by the coincidence of the two indicators, each of tham providing one part of the figure.
  • FIG. 3 there has been shown at 23 the body of a heel fitting (of which only the rear portion is shown) which is fixed on a ski 24.
  • a spring 25 belonging to the locking system for the jaw of the heel fitting which has not been shown since it does not form part of the present invention.
  • the spring 25 is supported against a part 26 fixed for rotation by a key 27, but free to move in translation inside the body of the fixing device.
  • a threaded portion 28 in which is engaged a threaded rod 29 provided with a gripping head 30 and which is fixed to a ring 31 carrying a threaded portion 32 engaged in a tapped hole 33 formed in the fixing device body 23.
  • the pitches of the threaded portions 29 and 32 have the same direction but of different amplitude, and the pitch of the threaded portion 32 is preferably twice that of the rod 29.
  • the transparent wall of the reading window is provided with a graduation which is thus stationary with respect to the fixing device body 23 and facing which there can be observed the displacement of the edge 35 of the threaded ring 32.
  • a safety binding for a ski boot comprising: a binding body mounted on a ski and provided with a jaw for retention of said boot on said ski, an elastic locking system housed inside said binding body and adapted to maintain said boot on the ski in a determined position, said locking system comprising two springs disposed in series and two parts movable in translation inside said body and fixed against rotation, each said part having a central threaded bore, each of said spring bearing, at one extremity, on a portion of said binding and, at the other extremity, on one of said two moving parts; a screw extending axially into said springs in series,
  • said screw having two threaded portions of opposite pitch engaged respectively in the corresponding central threaded bore of said moving parts, the actuation of said screw causing the simultaneous bringing together or moving apart of said moving parts;
  • one of said blades carries a graduated scale and the other blade carries a pointer adapted to move with respect to said scale.
