Definitions

  • the invention relates to a twist lock for a sports shoe, in particular a ski shoe, according to the preamble of claim 1.
  • Twist locks for ski boots are already known in various embodiments.
  • One of these known twist locks is disclosed for example in DE-C-22 13 720.
  • the twist grip which actuates the twist lock is directly connected in a rotationally fixed manner to a drive sheave acting as a drive pulley, the eccentrically arranged drive pins of which, during the rotational movement of the twist grip, successively engage with radial guide grooves provided as drive elements on the upper side of the pulley, so that gives a kind of Maltese cross gear for the rotary drive of the pulley.
  • the twist lock is designed according to US-A-37 38 027.
  • a twist lock embodiment of the type required in the preamble of claim 1 is known, for example, from EP-B-56 953.
  • the pawl of the pawl device is a suitable recess in the lower one Half of a housing body to be fastened to the shaft of the shoe is assigned, while the pawl, which is designed with an engagement tooth and a projecting shoulder and is biased upwards, is pivotably mounted in a recess in the lid-like upper halves of the said stationary housing body.
  • a toothed ring provided with engagement teeth is arranged within an approximately cup-shaped rotary handle arranged above this housing body such that its teeth can come into engagement with the pawl.
  • This toothed ring has an upwardly projecting, bush-like projection, which has a multi-start, external steep thread, which engages with a corresponding internal thread in the center of the rotary handle in such a way that when the rotary handle is to be rotated in one direction in the sense of a closure , this first carries out an axial empty movement on the steep thread until he has brought the toothed ring mentioned into engagement with the pawl and then takes this toothed ring with him in a further rotary movement, the kind of ratchet effect resulting from the interaction of the toothed ring and pawl.
  • twist grip is turned in the opposite direction by first turning the idle thread on the steep thread of the toothed ring until the toothed ring is disengaged from the pawl, after which the actual loosening while turning the twist grip fes is effected.
  • the invention is therefore based on the object of further improving a twist lock of the type required in the preamble of claim 1 in such a way that with an extremely sensitive adjustment of the twist lock and reliable maintenance of the adjustment made, a relatively simple and space-saving construction (in particular with a low overall height) is guaranteed.
  • the toothed ring is provided in a stationary and stationary manner and is incorporated directly into the top of the housing cover.
  • the pawl is from an intermediate disc arranged between the rotary handle and the housing cover, which is rotatably connected to the drive pulley for the pulley, so that the pawl can be rotated together with the intermediate disc and can be brought into engagement with the teeth of the toothed ring in the desired manner.
  • a particularly advantageous embodiment of the invention results from the feature of claim 2, such an embodiment being further developed in a particularly advantageous manner from the features of claim 3.
  • twist lock With this twist lock according to the invention, a relatively flat shape is ensured, inter alia, by the fact that - in contrast to the known embodiment explained last - the twist grip only needs to perform a pure rotary movement, i. H. the twist grip maintains its relatively small overall height even when it is turned in one or the other circumferential direction.
  • FIG. 1 shows an embodiment of how the twist lock 1 according to the invention can be attached to a ski boot, in particular to the outer boot formed by a plastic shell 2.
  • This belonging to a known ski boot plastic shell 2 is provided in the front and upper area with an approximately slot-like opening 3, which facilitates the insertion of an inner shoe (not shown) into the shell 2 and the putting on and taking off of the ski boot itself.
  • the plastic shell 2 also has an opening 3 covering, also made of plastic tongue 4 which is pivotable about a joint 5 arranged in the toe, so that it can be folded away from the main part of the shell 2.
  • the twist lock 1 contains a flat housing 6, which is fastened on the upper of the ski boot, which is formed by the plastic shell 2, preferably on the tongue 4, and a housing 6 arranged on the outside (top) of the housing for this purpose, rotatable rotary handle 7 and two pulling cable tensioning elements 8, 9, which are led out on opposite sides of the housing 6 and in this case are designed in the form of rope loops and with hook-like elements 10, 11 can be engaged.
  • These hook-like elements 10, 11 are fastened on opposite closing flaps of the plastic shell 2 of the ski boot.
  • a pulley By means of a rotary drive connection within the housing 6, a pulley can be rotated in one direction or the other with the help of the rotary handle 7, so that the effective length of the pull cord tension members 8, 9 in opposite directions in the sense of loosening by a corresponding rotary movement of the rotary handle 7 and tightening said closing flap (via the hook-like elements 10, 11) can be changed.
  • the tongue 4 is provided at the height of the twist lock 1 with two lateral extensions 4a, 4b, which serve to cover the two tension cable tensioning elements 8 and 9 respectively.
  • twist lock 1 The formation of the essential individual parts of the twist lock 1 can be seen above all in the exploded vertical sectional view in FIG. 2, while further details of these parts and their functional arrangement are illustrated above all in FIGS. 3 to 6.
  • the relatively flat housing 6 of the twist lock 1 has a relatively large, in the top view (see FIG. 4) circular recess 12 that is accurate in diameter and depth is adapted for receiving a pulley 13.
  • Guide channels 14, 15 open into this recess 12 at approximately diametrically opposite points, through which the corresponding ends 8a, 9a of the tension cable tensioning elements 8, 9 are led out of the housing 6 on opposite sides.
