Definitions

  • the present invention relates to a aid binding structure.
  • the ski binding further comprises a pair of supports, spaced apart from each other and affixed to the ski, which define a pair of holes for pivotal engagement with the lower end of a rod-like member, engageable with its upper end in a rear side region of a skier's leg.
  • the rear latch body is associated pivotally at its forward portion with the pin of the rod-like member and bears on the rear portion of a plate attachable to the ski. The oscillatory movement of the rod-like member and the rear latch body is resisted elastically by a telescoping pusher which acts between the rod-like member and the rear latch body.
  • the rear latch body has a degree of elasticity and can follow the ski flexing without being subjected to excessive stresses.
  • the simple rear support allows, moreover, shims to be inserted under the rear end of the rear latch body such that the inclination of the same and the rod-like member can be changed in the rearward stopped position.
  • the aim underlying the invention is indeed that of providing a ski binding structure which affords a reduction in the force required to ensure release in such a situation, but without favouring unintentional release while running.
  • a ski binding structure comprising a front latch means and a rear latch assembly for releasable engagement with footwear, said rear latch assembly comprising a pair of spaced apart supports affixed to the ski and defining a pair of mutually aligned holes along a substantially parallel axis to the plane defined by the ski being substantially perpendicular to the ski longitudinal direction for pivotal engagement with the lower end of a rod-like member engageable by contact at its upper side end with a skier's leg, a rear support, or pair of supports, attachable to the ski and being engaged oscillably by the rear portion of said rear latch assembly, said rear latch assembly engaging releasably a pair of latch members with its forward portion through a pair of moving hooks, also provided being actuation means connected

  • the cam element 8 may be shaped and positioned on the pin 14 such that, at a predetermined inclination of the rod-like member to the ski, the small plates 5 are caused to swing and displace the peg 4 from the coupling zone 5b to the elongate zone 5c, which enables in practice the rear assembly 1 to swing upwards.
  • the moving hooks comprise a pair of small pins 70 which protrude laterally of the rear latch body and engage in a shaped window 71 defined on a pair of small plates 72 constituting the latch members, which are mounted hingedly for oscillation about the axis 15 of the rod-like element.
  • the window 71 has a coupling part 72 flanked by an elongate part 73 which is advantageously formed as a segment of a circumference.
  • At least one of the small plates 72 defines a small plate 75 which extends laterally outwards, substantially perpendicularly to the plane of lay of the small plate itself and which supports a dowel 1, 76 adjustable in position, on which an arm 77 acts which is attached to the axis 15 and can engage by contact with the dowel 76 on the rod-like member reaching a predetermined inclination, obtaining disengagement of the small pins 70 from the coupling part 73 and consequent transition to the enlarged zone 74 where a limited oscillation is afforded for the rear assembly 1.
  • the small pins 70 and the pegs 4, for adjustment of their positions, can be carried on a bracket 11 coupleable with the body 1 by shimmings 12.
  • the moving hooks are composed of an outer tubular section 80 articulated to the rear assembly at the area of articulation of the elastic pusher 13.
  • Said outer tubular section 80 has a through hole 81 whereinto a dog 82 is inserted elastically which is provided on small rods 83 forming the latch member which are articulated at the axis 15 of the rod-like member 49 and are coupled telescopically with the interior of the outer tubular section 80.
  • the outer tubular section 80 has then a stop hole 84 wherein the dog 82 elastically engages to provide a stop for the oscillation of the rear assembly.
  • the actuating means consist of offcentered lugs 85 rigid with the pin 14 for connecting the rod-like member 13 which engage, at a set inclination of the rod-like member, with the pegs 82 perform their uncoupling from the through holes 81, with consequent possibility for a telescoping translation between the small rods 83 and the outer tubular section 80 and consequent possibility for oscillation of the rear assembly.
  • all of the coupling groups described above between the moving hooks and the latch member may be reversed without altering the inventive concept of this invention.
  • the moving hooks or the latch members may be provided with lever or the like means to enable manual disengagement of the moving hooks from the latch members, irrespective of the position and movement of the rod-like member and the elements connected thereto.
  • an object of the invention is to accomplish disengagement of the presser piston forming a part of the rear release assembly from the recess in the sole heel, and accordingly, disengagement of the footwear from the ski binding according to the movement of the rod-like member, as taken at a given point of its rotation or range of its rotation, and possibly in particular in combination with vertical forces acting from the sole (recess in the heel) on the presser piston.
  • Another object of the invention is to also accomplish easy insertion of the sole into the ski/binding combination and the possibility of disengaging the footwear from the means of latching it on the ski, both through the movement of the rod-like member by itself and by manually biasing the devices forming the subject of this invention, without being forced to manipulate other elements of the structure and with a reduced effort.
  • This invention also affords improvement and simplification, thanks to its particular features, as explained hereinafter, of the structures and details of the release combination forming a part of the rear latch assembly.
  • the rear latch assembly 1 has an outer body 19 with an internal cavity 20 and a rear engagement member 21 which affords connection to the rear support.
  • the body 19 has an upper hole wherein the rotating pin 14 is housed which withstands the thrust from the telescoping pusher 13.
  • a small window 22 which affords display of the adjustment of the piston thrust
  • the inner cavity 20 has at least one groove 23, advantageously provided at the zone affected by the window 22, which has the function of preventing rotation of the inner elements of the body 19.
  • an end cap 24 having a centre hole 25.
  • a cylindrical piston 26 which is provided, in the middle region thereof, with a substantially flat cutout 27 capable of accommodating a cross pin 28 for limiting the travel length of the piston itself.
  • the piston On its projecting portion, the piston has a conical lug 29 with a cutout 30 which can accommodate a rotating disk 31 having a vertical axis 32.
  • the piston may be advantageously hollow inside to accommodate a first cylindrical compression spring 33 which, through a diaphragm 90, acts on a second cylindrical compression spring which, on the one side, urges the cited piston 26 outwards, and on the other side, acts against a retainer cap 34 provided with a rotation-preventing lug, which engages in the groove 23 and has an inside threaded tang 35.

  • the screws 64 can be actuated by means of a screw-driver led through the hole pair 54.
  • the invention achieves the objects set forth, and in particular it should be emphasized that, with the binding described hereinabove, the rear latch oscillating block is held stationary in the running position and holds the footwear heel securely while affording, however, multidirectional release in the event of higher stresses, in the various directions, at preset values, acting on the re-entering piston.
  • the rod-like member 49 will swing while running, the latch members remain stationary, or axe moved by the action of the rod-like member or of members connected thereto, without releasing the engagement with the moving hooks and, hence, without releasing the rear latch assembly in its upward oscillation.
  • the assembly is automatically re-engaged with the ski through the moving hooks and the latch members.
  • the latch members or the dog of the embodiment of Figures 8 and 9 either with one hand, or a foot, or a ski pole, either directly or on a small lever interconnected with the moving hooks, the latter can be easily disengaged from the corresponding moving hooks, to thus realize the release of the sole from the footwear owing to the rear latch assembly swinging as described hereinabove to move out in any direction whatever, overcoming the downward component only of the thrust from the telescoping pusher and lowering the rod-like member, not only are the hooks disengaged but with the rodlike member fully down, the vertical component sign is reversed and the assembly raised, swinging on the rear support and fully releasing the sole.
  • the thrust originates from the spring, adjustable by turning the threaded shank arranged inside the inner threaded tang rigid with the end cap.
  • the piston is retained at the outlet by the cross-pin which allows it to move rearwardly in sufficiently for the release requirements.
  • inner shims may be introduced or the springs employed may be possibly replaced.
