Definitions

  • This invention relates to safety ski bindings, and more particularly to a front attachment for the type of ski binding in which the heel of a boot is urged forward by a resilient cable arrangement separately fastened to the ski or by a resilient lever arrangement known per se.
  • Known front attachments Vintended for cooperation with resilient means urging a ski boot forward toward the front attachment provide an abutment for the front portion of the boot.
  • the abutment is movable in a plane parallel to the top face of the ski while in engagement with the boot undertransverse stresses exerted by the boot and exceeding a set maximum value. The boot may thereby escape from the binding to avoid injury to the skier under excessive lateral stresses.
  • y l have found that the protection against injury provided by known safety bindings is inadequate if the stresses transmitted from the boot to the front attachment have a predominant component perpendicular to the top face of the Ski. lf the skis slip forward under a skier so that he falls backward, the known front Vattachments do not necessarily release the binding from the boot. Serious injuries to the foot or leg of the skier have resulted from such accidents.
  • An object of this invention is the provision of a front attachment for a safety ski binding of the type described, which permits disengagement of the boot from the ski under excessive stresses in any direction other than the direction of elongation of the ski.
  • Another object is the provision of a front attachment which releases the engaged boot when the undesired stresses exceed an Vadiustably predetermined value.
  • a further object ⁇ is the prevention of boot release by stresses smaller than the predetermined value, regardless of the direction of the stress.
  • FIG. 1 shows a preferred embodiment of the front attachment of the invention assembled with relevantportions of a ski and a ski boot, the view being in side elevation;
  • FIG. 2 shows the assembly of FIG. 1 in plan view
  • FIG. 3 shows a portion of the assembly of FIG. 2 in side-elevational section on the line IIL-lll;
  • FIG. 4 illustrates a modified embodiment ofthe invention in a sectional plan View corresponding to a section taken on the line IV-IV in FIG. 1.
  • the front attachment has a stationary portion and a fr,... y
  • the stationary portion of the front attachment consists of a flange 3 attached to the top face of the ski 1 by screws 4, of a conical standard E, and of a ball 6 integrally connected with the flange 3 by the standard 5.
  • the movable portion of the front attachment includes a socket member 7 formed with a cavity 8 and with an outwardly flaring passage 1t) which communicates with the cavity
  • the ball 6 is received in the cavity S and a portion of the standard 5, which has a cross section substantiaily smaller than that of the ball 6, passes outward through the passage 10.
  • the wall 8a of the socket member 7 in the cavity 8 is spherically curved toV conform to the ball 6.
  • the remainder 8b of the cavity is approximately cylindrical about an axis parallel to the normal direction of forward movement of the ski 1 and has a radial end wall 8c about this axis.
  • the passage 1G has an axial length 9 somewhat greater than the diameter of the ball 6 and a maximum width slightly greater than this diameter.
  • the socket member 7 is thus universally rotatable on the ball 6 within the limits set by abutment of the standard S against the walls of the passage 1t), and may pivot in a vertical plane' parallel to the direction of elongation of the ski into the position 7 shown in broken lines in FIG. l.
  • a coaxial bore in the forward portion 7a of the socket member 7 communicates with the cavity 8.
  • An internally threaded cylindrical sleeve 11 is axially movable in the portion 7a and is axially fixed by a set screw 12 in such a manner that the annular rear edge of the sleeve 11 is slosely adjacent the front surface of the ball 6.
  • a radial recess 6a in the ball 6 is normally axially aligned with the sleeve 11. Its orifice is spherically flared for conforming engagement with a ball 13 which is axially slidable in the sleeve 11.
  • a plug 15 is threadedly received in the front end of the sleeve ⁇ 11.
  • a recess in the radial rear face of the plug 15 abuttingly receives one end of the helical compression spring 14 the other end of which axially urges the ball 13 into engagement with the recess 6a of the ball 6.
  • the force of the spring may be adjusted by inserting a conforming key or a screw driver into a recess in the radial front face of the plug 15, and by rotating the plug.
  • the rear part of the socket member 7 has two integral lugs 7b, 7c respectively arranged at a vertical distance from the flange 3 and near the ange.
  • the lugs carry therebetween a threaded spindle 18 which is rotatable about its axis and secured against axial movement by a washer 19.
  • a boot engaging member 16 is threadedly mounted on the spindle 1S, The boot engaging member conformingly and slidably abuts against a fiat rear face 17 of the socket member'7 which is perpendicular to the direction of elongation of the ski.
  • the spindle 18 has a slotted head which may be rotated by means of a screw driver or suitable key to adjust the spacing of the engaging member 16 from the top face of the ski 1. Rotation of the boot engaging member about the axis of the spindle 18 is prevented by the rear face 17.
  • the boot engaging member 16 has a flat abutment face 16a spacedly parallel to the top face of the ski 1 for engagement with the projecting top of the boot sole.
  • the lower portion Ztl of the rear face of the boot engaging member 16 is approximately spherical about the center of the ball 6.
  • a round-headed pin 16h inserted in the center of the rear face portion 26 presents a face to the front edge of the boot sole for abutment in the direction of elongation of the ski 1.
  • the boot sole is reinforced Vface of the ski.
  • FIG. 4A The embodiment of the invention illustrated in FIG. 4A
  • the illustrated front attachment is assembled by slipping the socket member '.7 over the ball o and then inserting the sleeve lll of the resilient Stop assembly until it partially obstructs the passage ld.
  • the ball i3, spring ld and plug 15 are then placed in the sleeve l5 and the socket member 7 is rotated on its ball pivot until the ball 13 registers with the recess da and further rotation of the socket member by forces insuicient to overcome the force of the spring 14 is arrested.
  • the spring force may' be selected at will over a wide range by choice of a suitable spring and by threaded movement or" the plug l in the sleeve 11.
  • the assembled front attachment is then mounted on the skiV l by means of the screws 4 in fixed spatial relationship.
  • the front attachment is engaged with the boot as follows: ⁇
  • the boot is placed on the top face of the ski l so that the' recess in theV metal band 2l or in the front edge of the boot sole .receives the pin la! or the projection lob'.
  • the heel retaining cable is then tightened.
  • the boot engaging member 16 is moved toward the top face of the ski by rotation of thespindle I3 until the flat abutment face lido engages the boot lsole fom above.
  • the boot 2 transmits to the front attachment forces which are substantially parallel to the direction of elongation of the ski, andthe spherical front wall 8a of the socket member 7 is pressed against the corresponding surface portion of the ball 6.
  • the socket member 7 tends to rotate in a plane parallel to the top If these forces can overcome the force o f the spring i4, the ball 13 is displaced from the recess 6a and the socket member rotates into the position '7 (FIG. 2) whereby the boot 2 is released from the bindmg: y
  • the ball-and-socket connection of the invention provides equal resistance to relative movement of the boot engaging member lo and 0f the Ski l in all directions other than the direction of elongation of the ski. It maintains the boot engaging member in its normal op erative position against minor stresses and avoids accidental release of the boot from the binding.
  • the response of the front attachment to forces inclined relative to the direction of elongation can be adjusted where such adiustmen't is necessary.
  • the boot engaging member i5 is adjustable in a direction toward and away from the top face of the ski but cannot rotate relative to the socket member '7, thereby making the front attachment insensitive to forces which may otherwise induce relative movement of the socket member and the engaging member.
  • a front attachment for cooperation with resilient means urging a ski boot forward toward said front attachment, the attachment comprising,
  • saidsocket member having a spherical wall portion in said cavity rearwardly spaced from said passage and conformingly engaging said pivot member and (4) another wall portion opposite said sphericai wall portion and forwardly spaced from said passage, said -other wall portion being spaced from said pivot member and formed with an opening therethrough extending in said normal direction;
  • said sleeve member having an annular edge in said cavity, each portion of said edge being approximately equidistant from said pivot member when said sleeve member is in said position thereof.
  • said engaging means having a rear face portion substantially spherical about the center of said ball pivot member, said rst abutment portion being on said rear face portion.
  • said first abutment portion projecting from said rear face portion in said opposite direction.
