Definitions

  • ABSTRACT A buckle for plastic ski boots having a toothed tensioning lever pivotally supported on one instep portion and a tension lever pivotally supported on the other instep member and having means thereon engageable with the gaps between the teeth on the toothed tensioning lever.
  • the tension lever is constructed as a narrow member and has at its free end two lateral pins which project outwardly therefrom.
  • the toothed tensioning lever is substantially U-shaped and the legs of the U-shaped member are toothed so that the tension lever engages the U-legs in the gaps between the teeth thereon.
  • the invention relates to a tensioning lever buckle for ski boots, particularly for plastic ski boots, comprising a toothed tensioning lever pivotably supported on the one instep portion and a tension member which engages the gaps between the teeth of said tensioning lever and which is pivotably supported on the other instep portion.
  • the basic purpose of the present invention is to produce a tensioning lever buckle, mainly for plastic ski boots, which has a simple, strong structure capable of receiving great tension forces, furthermore makes possible an even distribution of the tension force over a larger instep length, and in which only one single tensioning lever buckle is required for the entire instep, at most, however, two buckles.
  • a tensioning lever buckle in which a toothed plate of a larger width is secured on the one instep portion, and a tensioning lever is provided on the other instep portion, which tensioning lever extends over a great length of the instep and which with its ends is supported on two bearing blocks on the instep which are spaced apart a large distance.
  • This structure has the disadvantage that the tension force is transmitted onto the one instep portion only at two points which are spaced far from one another.
  • the tensioning lever is connected through an adjusting screw to a rectangular wire bar having a great width and engaging the gaps of teeth of the wide toothed plate. Such a wire bar is not suitable for transmitting great tension forces. Furthermore, this is a relatively expensive structure.
  • a tensioning level buckle of the type mentioned in the beginning in which according to the invention the tension member is constructed as a narrow tension lever which at the end has two lateral pins projecting on both sides, and a wide, substantially U-shaped tensioning lever is provided, the two U-legsof which-are toothed, whereby the tension lever engages between the U-legs and its lateral pins engage the gaps between the teeth of the U-legs.
  • a swivel bearing for the tension lever, or also abearing block for the tensioning lever are arranged on base plates and'these are securedon the instep portion longitudinally of the instep edges, whereby the length of these plates is substantially greater than the width of; the tensioning lever.
  • FIG. 1 is a top view of the front part of a plastic ski boot
  • FIG. 2 is a cross section along the line lI-II-of FIG. 1 with a closedrbuckle;
  • FIG. 3 is the same illustration with an opened buckle
  • FIG. 4 is a top view of the front part of a ski boot having a buckle of a different construction
  • FIG. 5 is a cross-sectional view along the line V-V of FIG. 4 with the buckle opened;
  • FIG. 6 is the top view of a third construction of the buckle
  • FIG. 7 is a cross-sectional view along the line -VII of FIG. 6;
  • FIG. 8 is a further construction of the buckle in a perspective view.
  • the tensioning lever buckle consists substantially of a narrow tension lever 3 which is constructed as a tension member and which is pivotably supported on the instep portion 1 and which has at the free end two lateral pins 4 which project on both sides, and of a wide, substantially U-shaped tensioning lever 5, the two U-legs 5a of which are toothed, that is, are provided with rows of teeth 6, whereby the tension lever 3 engages between the U-legs 5a of the tensioning lever, and the lateral pins 4 of the tension lever are received in the gaps 7 between the teeth 6 of the U-legs 5a.
  • This tensioning lever 5 is supported pivotably about the bolts 24 on the instep portion 2 on a bearing block 8, while the tension lever 3 is pivotably supported on a swivel bearing 9.
  • the swivel bearing 9 and also said bearing block 8 are arranged each on a base plate 10 or 11, and these plates are secured on the instep portions 1 or 2 longitudinally of the instep edges In or 2a, so that the length L of said plates is substantially greater than the width b of the tensioning lever 5.
  • Said plates and also the bearing block 8 are secured to the instep portions 1 and 2 by means of rivets 23 or the like.
  • the plates 10 and 11 are advantageously arranged with their edges 10a and llafacing one another in the vicinity of the instep edges 2a, 1a.
  • the teeth 6 of the tensioning lever 5 are arranged on'the bottom side of the two U-legs 5a, and a lateral slot 16 is provided in the tensioning lever near the U-web 5b, which lateral slot permits the tension lever end and'its lateral pins 4 to penetrate therethrough as indicated by the arrow A in FIG. 3.
  • a tensioning lever 18 is provided in which the teeth 17 are arranged on the upper side of the two U-legs 18a.
  • a steel bolt 19 is provided at the end of the tension lever 3, the
  • the tension lever 3 is pivotable about two axes which stand perpendicularly to one another.
  • the swivel bearing 9 can be pivoted about a rivet 22 and furthermore the tension lever 3 is pivotable about a bolt 20 which is supported in the eyes 21 of the swivel bearing 9.
  • FIGS. 6 to 8 illustrate further embodiments of the new buckle in which the tension lever 3a is hingedly connected by a rivet bolt 25 or 25a to a swivel plate 26 or 26a which forms an extension of the tension lever and which itself is pivotably supported about an axis 27 which is positioned perpendicularly to the rivet bolt on a bearing block 28 of the base plate 29.
  • the tension force of the lever 3, also 3a is favorably transmitted onto the swivel plate 26 or 26a which is only stressed by tension.
  • FIGS. 6 and 7 permits a longitudinal adjustment of the tension lever 3a on the swivel plate 26a.
  • several circular holes 31 which are each connected by a slot are provided in said swivel plate, the diameter of said holes corresponding to the diameter of the rivet bolt 25a, whereby the rivet bolt which is fixedly connected to the tension lever 3a is flattened transversely to the tensioning lever (indicated at 32) in such a manner that it, after swinging of the tension lever 3a for 90, can be moved through the slot 30 to the next hole 31.
  • two adjusting screws 33 are arranged in the baseplate 29 which pw ot ablysii ppcmhfinsion lever 3a so that at a closed tensioning lever buckle, the swivel plate 26 exerts a pressure on the heads of the adjusting screws 33.
  • This pressure can be regulated by the adjusting screws 33 which can be screwed into the base plate 29.
  • a tensioning lever buckle particularly for ski boots, having a toothed tensioning lever pivotably supported on the one instep portion and a tension member which engages the gaps between the teeth of said tensioning lever and which is pivotably supported on the other instep portion, comprising the improvement wherein said tension member is constructed as a narrow tension lever which, at the free end thereof, has
  • the improved tensioning lever buckle according to claim 1 including a swivel bearing for the tension lever and a bearing block for the tensioning lever, both of said swivel bearing and said bearing block being arranged on separate base plates secured on the instep portions longitudinally of the instep edges whereby the length (L) of these plates is substantially greater than the width (b) of the tensioning lever.
  • each of said U-legs of said tensioning lever has a slot therein adapted to receive one of said checks.
