Definitions

  • the present invention relates to a ski binding, and more particularly to a ski binding in which only the toe of the boot is firmly held, both against lateral movement, as well as against longitudinal movement, and more particularly to the binding in which the heel is free of the ski.
  • Various safety bindings are known, in which the ski boot engages a toe member to hold the toe down. The ski boot is then held against lateral movement, as well as against the ski, by a heel catch member, which engages over the projecting welt formed of the heel portion of the sole of the ski boot, or with an additional metal engagement member.
  • Such bindings known as step-in bindings have the advantage that cables around the heel of the boot are avoided, thus making it unnecessary to bend over when securing the boot to the ski in the binding.
  • pressure members have been proposed which can be operated by a ski pole. Avoiding the necessity of having to bend when fastening the skis improves the usefulness of the binding to the user, and avoids possible shifting of loads being carried on the back.
  • step-in bindings heretofore proposed all use a toe piece and a heel piece, to secure the heel to the ski and provide for lateral control of the skis.
  • Such bindings are undesirable when used for cross-country skiing where the heel should be able to lift off the ski. Lateral control of the skis must, however, be assured as before.
  • the boot is formed with a recess or notch. It fits into a pair of toe-brackets, to provide for lateral guidance of the boot.
  • a pair of spring members which have inwardly projecting flanges gripping over the welt of the toe of the ski boot and a projecting catch, which engages in the notches formed in the sole of the boot .
  • the flanges and the catch pass through a slot formed in the toebrackets.
  • the forward ends of the springs are extended beyond the ski boot and interconnected by a pair of links, extending upwardly, and being together slightly longer than the distance between the springs.
  • the links When the links are depressed, the springs are spread thus releasing the catches from the ski boot so that the boot 3,466,056 Patented Sept. 9, 1969 can he slid out from under the flanges covering the welt.
  • FIG. 1 is a schematic top view of the binding in accordance with the present invention.
  • FIG. 2 is a schematic view of the toe piece of a ski boot with the notches formed therein;
  • FIG. 3 is a perspective view of a reinforcing element
  • FIG. 4 is a perspective view of one toe-bracket
  • FIG. 5 is a top-perspective view of a top-release arrangement in accordance with the present invention.
  • a ski a portion of which is shown at a, has the binding secured thereto.
  • a bottom holding plate 1 is formed into brackets 2.
  • the holding plate 1 formed in two parts, is secured to the ski for example by holding screws 1'.
  • Elongated spring rails 3 are secured to the rearmost portion of the toe-brackets 2. for example by rivets 3'.
  • the spring rails 3 are carried along the brackets 2 beyond the front ends, with respect to the ski, of the brackets 2. The forward ends are bent inwardly, to form inwardly extending brackets 4, having a hole punched therethrough (see FIG. 4).
  • a holding member 6, having a catch hook 5 is riveted to the side springs 3 by means of rivets 6' (FIG.
  • the inwardly extending bracket 6 is mounted on the springs in such a manner that it will cover the upper side of the sole c of a ski boot b, see particularly FIG. 2.
  • the catch hooks 5 fit into a pair of notches or recesses 5', formed into the toe piece of the ski boot.
  • the front side of the ski boot is reinforced by means of metal covers or plates: 9, set into the sole of the ski boot and riveted through from the top.
  • the boot To engage the boot with a ski, the boot is pushed beneath the brackets '6 until the catch 5 engages into the notches 5'. This permits the springs, spread as the shoe is pushed inwardly, to snap towards each other, so that the projections 5 will engage behind notches 5 and hold the boot against removal from the ski. At the same time, the toe of the boot is held downwardly, leaving the heel free to move. Lateral excursions of the boot with respect to the ski are prevented to a certain extent by the stiffness of the springs 3, to an additional extend by the presence of the brackets 2. Excessive stress, sideways, can release the catches 5 from recesses 5'.
  • the inwardly bent over brackets 4 of the two side rails 5 are linked to a pair of arms 10 (FIG. 5), which arms 10 together are longer than the normal distance between the spring rails 5.
  • the arms 10 form, centrally, a joint which extends with the arms upwardly.
  • Projections 7, at the inside of the brackets 6 (FIG. 1) prevent release of the brackets from notches 8 (FIG. 4) in the side brackets 2 and prevent excessive lateral extension of the springs.
  • Arms 10 are riveted to inwardly turn brackets 4 by means of rivets 10'; at the center, they are movably connected by a rivet 11', preferably covered by an inverted U-shaped cover 11, to which a cup 12 can be riveted or welded. The tip of a ski pole can be placed into the cup 12 to spread spring rails 3.
  • the present invention has been illustrated in combination with a ski binding in which a pair of front-brackets provide for lateral guidance of the boot. These brackets could, however, be omitted if the springs themselves are strong and stiff enough. Further, the toe piece of the binding can be combined with other attachments, if desired, for use as a ski binding for downhill running, when it is desired to have the heel retained closer to the ski, than customary for crosscountry use.
  • Ski binding to hold a ski boot to a ski the boot having recesses formed at opposite sides near the toe thereof, said binding comprising a pair of elongated spring members (3) adapted to have one end thereof secured to the ski (a and extending longitudinally of the ski adjacent the toe of the boot (b), said spring members (3) being biased towards each other;
  • brackets secured to said elongated spring members (3) at the other ends thereof, said brackets including a holding plate (6) essentially parallel to the top surface of the ski to grip over the welt (c) of the sole of the boot (b), and means engaging said recesses (5) in the sole of the boot, and
