Definitions

  • ABSTRACT In a ski binding of the toe binding type with clamping bail, in which a spring-loaded lever supported on the bail for pivotal movement releasably and adjustably engages a fixed toothing, the lever is supported directly in lateral angles formed by the legs of the bail, so as to be wedged therein, whereby the bail itself will afford the spring load required for making the lever engage the toothing and is also held resiliently engaged in the toe iron lugs.
  • the present invention has for an object to eliminate this drawback. According to the invention this is achieved due to the fact that the lever is supported directly on the legs of the bail at a point where these are formed with oppositely directed angles, the lever engaging the legs laterally within these angles.
  • FIG. 1 is a top view of the binding in a preferred embodiment.
  • FIG. 2 shows the same binding in vertical longitudinal section along the line IIII in FIG. 1.
  • FIG. 3 shows another embodiment in a corresponding section.
  • FIG. 4 is a sectional view taken along the line IVIV in FIG. 3.
  • the binding shown in FIGS. 1 and 2 has a toe iron 1 of a form which in most respects is well known for toe bindings with clamping bails, having a foot plate 2 with integral lateral flanges 3 which at the rear constitutes the toe iron lugs and at the front are curved inwards in front of the toe of the boot and again forwards along either side of a central extension of the foot plate.
  • the foot plate has locking studs 4 for the sole of the boot and screw holes 5 for the attachement on the ski, and in the toe iron lugs there is pivoted a clamping bail 6 having free rear extremities resiliently engaging recesses 7 in the toe iron lugs, and the legs of which are curved inwards over the sole rim and further forwards beyond the toe iron with the bight portion 8 at a distance in front of the extension of the toe iron.
  • a keeper member 9 having at the front a vertical toothing 10 for adjustable engagement with a rearwardly projecting hook I] on a downwardly extending arm 12 of an angular lever 13, the other arm 14 of which extends rearwards from a supporting point in the bail 6.
  • a transversely bent portion 15 of the lever 13 which is formed of a bent piece of metal sheeting, is formed with a recess 16 in each lateral edge and here engages lateral angles'17 formed in the legs of the bail.
  • the lever 13 has such dimensions relative to the bail 6 that it keeps it under spring bias in the supporting recesses 7, so that the lever itself is subjected to compressive spring-load in the transverse direction.
  • released position of the hook 11 it will therefore be held in a well defined neutral position by means of the angles 17 and can only be moved from this position by a wedging action while overcoming lateral resilient resistance in the bail.
  • the neutral position is chosen so that when the bail is pressed down against the sole rim the book 11 will slide over the teeth of the toothing 10 while overcoming resilient resistance in the bail and will therefore in locked position be held in engagement with the desired notch.
  • Release is effected by downward pressure on the arm 14, which is usually accessible from above, and, besides, is formed with a recess 18 facilitating release by means of the point of a ski pole.
  • FIGS. 3 and 4 differs from the one shown in FIGS. 1 and 2 in that the keeper member 9 is omitted and the side flanges 3' of the toe iron are instead provided with a toothing 10' at the front edge.
  • the bail 6' is shorter than in the first embodiment, so that the bight 8' extends just in front of the toothing l0 and inside the arm 12' of the lever 13'.
  • the lever 13' has a transversely bent portion 15' between the angles of the bail legs, but unlike in the embodiment shown in FIGS. 1 and 2, this portion is here bent downwards from the arm 12' instead of upwards, and the actuating arm 14' then extends up between the bail legs in order to be accessible on top of the bail.
  • FIGS. 1 and 2 has the advantage of requiring particularly little force for attachement, whereas the embodiment shown in FIGS. 3 and 4 has the advantage of a particularly compact design.
  • ski binding comprising a toe iron having upstanding toe iron lugs, a clamping bail having a pair of rear leg portions shaped to engage the sole rim of a boot about its toe portion with the rearward end of said rear leg portions pivotally mounted on said lugs, a keeper means fixedly disposed forwardly of said toe portion, said clamping bail having a pair of forward leg portions terminating into a forward bight portion; said improvement comprising a latching lever pivotally supported at its midsection by said forward leg portions, said lever having a forward arm portion projecting downwardly toward and forwardly of said keeper means and having a rearward arm portion which is accessible from above, said forward leg portions being formed with oppositely directed angular sections that laterally engage said latching lever mid-section to provide a spring-load on said lever in the transverse direction; and hook means for releasably connecting said forward arm portion to said keeper means.
