  • ABSTRACT The disclosure herein describes an apparatus and method for compensating for the longitudinal movement of a safety ski binding and thereby protecting the skier when falling.
  • the moving part of the ski binding is subjected to the action of a resilient force which resists the displacement of the moving part in one direction; this resilient force varies as a function of the moving part and, at the same time it varies, the component of this force which acts on the moving part of the binding parallel with the direction of movement thereof, is maintained at an appreciably constant value.
  • PATENTEB MAY 2 2 I975 SHEET [1F 6 PATENTEB HAY 22 I975 SHEET 6 OF 6 APPARATUS AND METHOD FOR COMPENSATING FOR THE LONGITUDINAL MOVEMENT OF A SAFETY SKI BINDING
  • the present invention relates to safety ski bindings, and more particularly to bindings, a portion of which at least is susceptible to movement along the longitudinal axis of the ski.
  • Known types of safety bindings for skis intended to protect the skier when falling forwards, backwards, or sideways, are usually mounted on the ski so that they may slide longitudinally, for example in grooves, and may thus be adjusted to different sizes of boot. Furthermore, these known bindings are frequently equipped with an arrangement which applies a constant longitudinal thrust to the moving part of the bindings, so that they may bear against the boots. The purpose of this longitudinal thrust is to keep the bindings pressed against the boots, in spite of any movement the bindings may make.
  • the movements for which this known arrangement is intended to compensate may be caused, for instance, by temporary bending of the ski, a type of boot unsuitable for the adjustment at the binding location, incorrect longitudinal adjustment of the binding location on the ski, or the presence of foreign matter, such as snow, between the binding and the boot.
  • This type of known arrangement is resilient and, in order to assure its resiliency, it makes use either of a part of the energy of the resilient system ensuring the safety of the binding in the event of a fall, or of the energy of a resilient system independent of the binding mechanism.
  • the mechanism ensuring the safe functioning of the binding is known to be adjusted to release in response to a specific stress applied by the boot to the binding, and it is therefore essential that no external stress shall temporarily modify the calibration of the safety mechanism.
  • variable reaction of this known type of arrangement on the moving part of the binding does in fact modify this calibration, which leads to irregular and unexpected functioning of the safety binding, with the result that skis fitted with these bindings are dangerous.
  • a device of this kind must be simple, reliable in operation, of small size, inexpensive, rugged, and it must require a minimum of moving parts.
  • a movement-compensating device comprises'a resilient unit arranged between a fixed element integral with the ski and the longitudinally mobile part of the binding, the said resilient unit exerting upon this mobile part a force which opposes the force which causes the binding to move longitudinally, the said force having an appreciably constant value regardless of the extent of longitudinal movement of the moving part of the binding.
  • the compensating device according to the invention is therefore particularly well suited to exert an almost constant opposing force on the moving part of the binding which is capable of moving longitudinally over a relatively short distance. It is therefore sufficient if the design and arrangement of the device produce the desired result while functioning within relatively narrow limits. This consideration therefore permits the use of a simple and inexpensive device.
  • the said binding is preferably stopped, in such a manner that the resilient unit exerts upon the moving part a force opposing the movement of the binding towards what is known as the rearward position, one component of this force acting parallel with the longitudinal movement of the binding and having a value equal to that of the constant opposing force acting on the binding while it is moving.
  • the resilient unit comprises means which, when the resilient force thereof varies while the moving part of the binding is moving, modify the orientation of this resilient force in relation to the longitudinal direction in which the force displacing the moving part acts, with the result that the angle formed between the said resultant and the direction of displacement varies in proportion to the variation in the resilient force, which means that the component of the said resilient force acting upon the moving part of the binding parallel with the direction of displacement has an almost constant value.
  • the resilient unit comprises at least one guided spring, the axis of which is kept in a straight line, the ends of the said spring being connected to elements co-operating on the one hand with the fixed structure of the ski and, on the other hand, with the moving part of the safety binding.
  • the compensating device according to the invention may vary in design, depending upon whether it is desired to obtain a device exhibiting high functional accuracy or, on the contrary, relative accuracy, i.e., one which allows minor tolerances in the constant value of the opposing force.
  • the design of the device may be extremely simple and economical, whereas if high functional accuracy is required, the design of the device will be somewhat more complex and slightly more costly.
  • one form of execution of the device comprises a single spring mounted around a telescopic support having a rectilinear axis and exhibiting end flanges against which the ends of the springs rest, one end of the said support being hinged to a fixed pivotpoint on the ski located to one side of the longitudinal axis thereof, whereas the other end is hinged to a pivot integral with the moving part of the binding and located in the vicinity of the longitudinal axis of the ski.
  • the axis of the spring support is at an angle to the longitudinal axis of the ski, and the action of the device upon the moving part of the binding comprises a longitudinal component and a component transverse to the direction of movement of the moving part of the binding.
  • a second type of device comprising guide ramps, the shape of which may be calculated and adjusted with accuracy, thus making it possible to obtain an opposing force acting upon the moving part of the binding, which will have a constant value with very good approximation.
  • Gne form of execution of this type of device consists of a compression spring arranged perpendicularly to the longitudinal axis of the ski and inside the moving part of the binding, the said spring acting upon at least one retractable element also located within the said moving part, which it urges laterally outwards, causing it to co-operate with a cam profile integral with the ski and extending longitudinally.
  • the distance between the said cam and the longitudinal axis of the ski decreases progressively from front to rear; the device preferably comprises two opposing retractable elements, such as balls or rollers which compress between them a single spring and which co-operate respectively with a cam profile, the two cam profiles being symmetrical with the longitudinal axis of the ski.
  • the devices comprise two parts pivoting respectively about vertical axes integral with the ski, one of the said parts being subjected to the action of a spring attached to a fixed point of the ski and pushing the second part into contact with the moving part of the binding, the said parts exhibiting cam profiles which co-operate and slide upon each other in almost spot contact, which makes frictional forces almost negligible.
  • a return spring kept in a straight line is stopped at one end by a fixed part integral with the ski, the other end of the said spring resting on a toothed wheel to which it applies a torque, the said toothed wheel engaging with a rack mounted to slide along the longitudinal axis of the ski in a sliding support, the front end of the said rack abutting against the moving part of the binding.
  • the said spring is in almost spot contact with the toothed wheel, preferably along a chord-like section thereof, the distance between the axis of the said wheel and the point of contact with the spring varying in proportion to the restoring force of the spring.
  • a spring is mounted on a telescopic support intended to keep it substantially parallel with the longitudinal axis of the ski, one end of the said support being integral with the ski while the other end pushes into contact with the moving part of the binding an intermediate part mounted on a pivot remote from the longitudinal axis of the ski and from the axis of the spring, the said intermediate part having a profile which co-operates with a conjugate profile pertaining to the mobile part of the binding.
  • the profile of the said intermediate part may co-operate with a conjugate profile pertaining to a fixed part of the binding, via an element integral with the moving part of the binding and moving within the two profiles.

  • FIGS. 12 and 13 show a plan view in two extreme conditions of a device according to a sixth form of execution.
  • I is a central section of the ski and 2 is the moving part of a safety binding, for example, a heel-piece carrying a holding jaw 3 for a boot (not shown).
  • a safety binding for example, a heel-piece carrying a holding jaw 3 for a boot (not shown).
  • the moving part of the binding will be considered as a heel-piece but it is to be understood that it might also be some other binding element.
  • the said heel-piece may move longitudinally along axis XX of the ski, sliding on lateral tongues 4, with which it is equipped, in corresponding slides 5 integral with a bracket 6 attached to the ski in any appropriate manner.
  • Slides 5 have longitudinal stops 7, at least at their front ends, which limit the forward travel of the heelpiece. These stops, which may be of any known type, are preferably simultaneously adjustable on slides 5.
  • Rear stops might also be provided to limit the rearward travel of the heel-piece, but this is not mandatory.
  • the said compensating device consists of a telescopic element comprising a cylinder 11 in which a rod 12 slides.
  • cylinder 11 The free end of cylinder 11 is fixed to flange 13 of a female part 14 of the ball joint, male part 15 of which carries a seat 16 permanently attached to ski 1, in an area laterally remote from longitudinal axis XX and preferably in that half of the ski opposite to the location of seat 8 of the ball joint attached to the binding. It will also be observed in the drawing that seat 16 is located to the rear of bracket 6 in which the binding slides.
  • rod 12 also carries at its free end a female part 18 of flanged ball joint 17 which co-operates with male part 9 of the ball joint carried by the heelpiece.
  • a compression spring 19 is mounted around telescopic element 1l-l2, the ends of the said spring resting against flanges 13 and 17.
  • rod 12 In the vicinity of flange 17, rod 12 has an expanded section 20, the shoulder of which is intended to come into contact with the free end of cylinder 11 in order to limit the compression travel of spring 19 (as shown in FIG. 3).
  • the expanded section comes into contact with the cylinder, it is impossible to compress device any further, and the said device therefore becomes a stop, limiting the rearward travel of binding 2.
  • the device is therefore free to contract or expand as indicated by the double arrow B in FIG. 1, and to pivot about ball joint as indicated by double arrow A.
  • the angle between the axis of device 10 and longitudinal axis XX of the ski is preferably between 30 and 60, and this applies over the entire travel of the binding.
  • spring 19 when the binding is in the forward position shown in FIG. 1, spring 19 is already in the compressed condition, exerting upon the moving part of the binding a force, the resultant of which, following the axis of the spring, is shown at 22; the said force has a longitudinal component 23 and a transverse component 24.
  • angle a between the axis of device 10 and longitudinal axis XX increaseas proportionally, as does transverse component 24.
  • longitudinal component 23 is invariable, and the opposing longitudinal force which it represents has a constant value, regardless of the movement of the heel-piece.
  • binding 2 is shown in its maximal rearward position, and it may be seen that resultant 22 and transverse component 24' are greater than resultant 22 and component 24 in FIG. 1, just as angle a is larger than angle a; only longitudinal component 23 remains the same in both figures.
  • FIGS. 4 and 5 makes it possible to balance the friction between the binding and the two slides 5, since this device cancels out any transverse component.
  • two telescopic spring supports 25 and 25 are identical with support 10 in FIGS. 1 to 3 and are arranged symmetrically in relation to longitudinal axis XX of the ski.
  • the feet of ball joints 26, 26 of the said symmetrical supports are mounted on seats 27, 27 respectively, while sockets 28, 28 are mounted on a common seat 29 attached to the rear of heel-piece 2.
  • Ball joints 28, 28' are in the vicinity of axis XX whereas rear joints 26, 26 are spaced symmetrically from axis XX, in order that supports 25, 25 may be at an angle to axis XX.
  • Springs 30, 30 of the supports may, with advantages, have identical characteristics, and resultants 31, 31 of the reaction of these springs on binding 2 are equal.
  • the longitudinal components add together, as shown by vector 33. This component acts exactly along the line of axis XX of the ski.
  • heel-piece 2 may slide longitudinally along ski 1 on lateral tongues 4 in slides 41 on a bracket 40 attached to the ski, as in the previous forms of execution.
  • heel-piece 2 Towards its rear end, heel-piece 2 has a hole 42 perpendicular to longitudinal axis XX of the ski, the said hole opening into longitudinal grooves 43 on each side, the height of which is practically equal to the diameter of hole 42.
  • a compression spring 44 Located in hole 42 is a compression spring 44, the ends of which rest against two retractable elements such as balls 45, which are thus urged towards the outside.
  • Each stop plate 46 partially obstructs corresponding groove 43, but provides a longitudinal gap 48 wider than the groove which allows relevant ball 45 to project outwardly as shown in FIG. 7, but without being able to leave the heel-piece.
  • Each ball 45 is kept in alignment with spring 44 by any appropriate means, such as, for example, a spherical ball-receiving seat provided in the edges facing the retaining plate.
  • Each ball 45 is in constant rolling contact with a ramp 49 on the outside of the heel-piece; the said ramp extends longitudinally at the level of gap 48 formed by retaining plate 46, and are produced in the edge of two brackets 50 symmetrical with longitudinal axis XX of the ski and are attached to member 40 by means of screws 51.
  • the shape of the ramps resembles that of a very elongated recumbent S. In other words, the distance between the ramp and longitudinal axis XX decreases progressively from front to rear.
  • the compensating device consists of two parts 60 and 61 mounted to pivot about fixed vertical axes 62 and 63 respectively, the latter being integral with a common support plate 64 mounted on the ski behind heel-piece 2.
