Definitions

  • the invention relates to an elastic return device for ski safety binding comprising a spring helical and having a variable stiffness as a function of the loading speed, in which the spring works in compression.
  • Patents FR 1 454 511, DE 24 15 957, DE 26 34 649, FR 2 424 040, FR 2 625 687 and FR 2 661 334 we know fixings in which a shock absorber is associated to a spring in order to avoid tripping nuisance due to shocks or the like.
  • This shock absorber allows to vary the resistance force at the opening of the binding depending on the solicitation speed, tripping force being raised for violent stresses and, by against, relatively weak for solicitations sweet. This allows to better adapt the response of the front fixing with mechanical resistance characteristics of the leg of a skier, who is able to resist at high intensity stress, but brief, while it risks breaking in the event relatively low intensity loading, but exercising for a relatively long period of time long.
  • the damper is mounted in series with the spring in the fasteners described in patents FR 1 454 511 and DE 26 34 649.
  • the damper is mounted coaxially inside spring.
  • Patent application DE 24 15 957 further proposes mount a spring between the two pistons of a shock absorber hydraulic, inside the cylinder.
  • the damper is of the hydraulic piston type described in patent FR 1 454 511, that is to say constituted a cylinder and a piston delivering a liquid in this cylinder through a nozzle. It's about therefore always of a conventional damping device separable from the spring and working in parallel or in series with the spring.
  • the present invention aims to achieve a simple, compact, robust variable stiffness device and capable of being mounted in a front binding or rear without modification of this fixing.
  • the elastic return device is characterized in that it comprises a plastic material fluent interposed between the turns of the spring, such so that the stiffness of the spring increases with speed of its compression.
  • the plastic material can constitute a helical cord between the turns of the spring or appear like a tubular cylinder in the thickness of which the spring is drowned. In both cases, the interior of the elastic return device remains free for passage of a tie rod, so that the reminder can be mounted in a front tie rod without modification of the fixing, instead of usual spring.
  • the fluent plastic material can also constitute a full cylinder, at least in its central part, the spring being embedded in the peripheral zone of this cylinder.
  • a reminder device can be mounted in a rear binding without modification thereof.
  • the central part of the cylinder essentially constitutes mechanical support for spring and material plastic located between the turns of the spring and, optionally and incidentally, a central shock absorber auxiliary.
  • Figure 1 is an axial sectional view along a plane vertical of a front fixing or stop.
  • Figure 2 is an axial sectional view along a plane vertical of a rear or heel piece.
  • the front fixing or stop shown in Figure 1 is similar to the attachment described in patent EP 0 295 372 to which reference may be made for more details.
  • This attachment includes a base 1 secured a fixing body 2 on which is mounted a jaw made up of two arms, including arm 3 visible in Figure 1, mounted pivoting independently from each other around two distinct vertical axes formed by rounded vertical edges of the body 2, arranged symmetrically on either side of the plane vertical symmetry corresponding to the section plane, as described in patent EP 0 295 372, so as to be able to move away from each other and come to lean against the end of the shoe by rollers 4 and 5.
  • the radial holding of the cord 11 is provided internally by a telescopic tube in two parts 12 and 13 and, externally, by an envelope 14 of elastic material, such as rubber, or a heat-shrinkable sheath, the ends are folded over the ends of the tube telescopic.
  • the telescopic tube 12/13 and the casing 14 constitute, preferably a sealed compartment.
  • the material 11 is preferably a material making part of the family of silicone rubbers or EPDM or PDMS, or the like possibly loaded organic or mineral fillers such as silica pyrogenic talc, colloidal silica. These charges allow to give the material thixotropic properties, that is to say to modify its viscosity to obtain a more or less pasty or gelatinous state.
  • Such material is fluent and has a variable stiffness in depending on the loading speed, in particular compression speed. In compression, the spring 10 thus coated therefore behaves like a spring to variable stiffness.
  • variable stiffness device is presented as a tubular element that cannot be fitted instead of the usual spring in a fixing of the type described in patent EP 0 295 372.
  • Fluid plastic material could also occur in the form of a sleeve in the thickness of which spring 10 would be submerged.
  • Fluid material could be present on a part only the length of the spring.
  • the rear or heel piece shown in the figure 2 has, in known manner, a fixing body 15 slidably mounted on a slide, not shown.
  • a jaw 16 On this body 15 is articulated a jaw 16 around an axis 17, jaw intended to come to rest on the shoe heel and having a lower part 16a in the shape of a pedal for putting on the shoe pressure on this pedal.
  • jaw 16 pushes back a piston 18 against the action of an elastic device 19 constituted of a spring 20 embedded in the peripheral region a cylindrical body 21 of fluent plastic material with variable stiffness depending on the stressing speed.
  • This material 21 is of the same type as the material 11.
  • the elastic return device 19 is mounted between the piston 18 and a nut 22 mounted itself on a screw 23 provided with a flange 23a by which it is based on the fixing body 15.
  • the nut 22 drives a cursor 24 for displaying the setting of the precompression of the device 19 by means of the screw 23.
  • the body 21 has, in its ends, two holes cylindrical axial, one for part engagement tubular central 18a of the piston, part which ensures the attachment of the piston 18 and of the device 19 for mounting, the other axial hole allowing the passage of the screw 23.
  • the body 21 is also provided with an envelope elastic 25.
  • the central area of the body 21 essentially serves as a support for the part of the fluent material located in the spring. Incidentally, this central area can also have a damping effect. In the construction shown, however, this effect is negligible given the very small section through which the hollow portion 18a of the piston 18 rests on the body 21.
  • the device 19 could be made in a telescopic tubular form as in the case of the front attachment shown.
  • the fluent material could be present, between the turns of the spring, only over part of the length of the spring.
