Definitions

  • the invention relates to a jaw body according to the preambles of claims 1, 10 and 12.
  • a jaw body according to the preamble of claim 1 has already been described in AT-PS 375 269.
  • the sole holder which can be rotated in a horizontal plane, can also be pivoted to a limited extent in a vertical plane on a transverse axis which passes through the bolt.
  • the flat rear side of the sole holder is acted upon by a piston from the release spring, which tries to pivot the lever arm of the sole holder, which is removed from the spring, against the upper side of the ski.
  • This jaw body has the disadvantage that the sole thickness may have little scope to make a correct fixing by the sole holder possible.
  • the manufacture of the sole holder is difficult insofar as it is penetrated by a hole which extends obliquely to the upper and lower boundary surfaces and is approximately oblong in plan view.
  • Another jaw body is described in DE-OS 19 43 973. This is pivotable about an axis running perpendicular to the top of the ski and held in the driving position by means of an adjustable locking device.
  • the jaw body On the side opposite the latching device with respect to the pivot axis, the jaw body has a vertical bore in which there is a sleeve with an internal thread. A further threaded sleeve is screwed into this sleeve and is penetrated by a screw bolt carrying a sole holder. There is a coil spring between the nut of the bolt and the second threaded sleeve, which presses the sole holder downwards.
  • FIGS. 7 and 8 a toe is shown in FIGS. 7 and 8, in which a sole holder, which is under the influence of a spring pushing it upwards, is displaceably guided on a bolt.
  • the bore of the sole holder has threaded segments in two diametrically opposite areas, which extend over approximately 90 °.
  • the bolt is flattened on two sides and carries threaded segments between the flattened areas, which also extend over approximately 90 °.
  • the threaded segments of the bolt and the bore can be released from one another for the adjustment process (see FIG. 8) and brought back into engagement with one another to fix the sole holder (see FIG. 7).
  • An automatic adjustment of the sole holder is not possible with this version. Rather, the desired position of the sole holder, as described, must be set by hand.
  • a front jaw which carries a vertically extending, rotatably mounted threaded bolt in its rear region. This passes through a threaded hole in a sole hold-down and has a slot in its head, which is used for the use of a screwdriver. By turning the bolt, it is possible to adjust the distance between the sole retainer and the base plate of the toe piece to the thickness of the sole of the ski boot. This process is time-consuming, which has an adverse effect on assembly and, in particular, on rental ski operation.
  • Document FR-A-2,556 602 describes a bakery body which consists of a bearing block to be fastened to a ski and a housing which carries a sole retainer and accommodates a release spring and which can be pivoted in a horizontal plane against the force of the release spring.
  • a vertically extending bolt which serves as the pivot axis, is arranged in the housing and is secured against axial displacement relative to the bearing block.
  • Document FR-A-2,537,442 shows a similar jaw body.
  • This has a bearing block to be fastened to a ski and a housing carrying a sole holder and receiving a release spring which can be pivoted relative to the bearing block in a plane parallel to the top of the ski and in a normal plane to the latter against the force of the release spring.
  • a vertically extending bolt which serves as a pivot axis for the housing and has a ball-joint-like head, is arranged in the bearing block.
  • the bolt is a screw bolt which is screwed into a threaded bore in the housing or the bearing block.
  • the screw bolt In order to adjust the height of the sole hold-down to differently thick shoe soles, the screw bolt must be turned, which leads to the disadvantages mentioned above.
  • the object of the invention is to eliminate the disadvantages of the known designs and to create a jaw body which, on the one hand, is simple in construction and, on the other hand, enables the sole holder to be adjusted automatically even if the thickness of the shoe sole varies within the prescribed tolerance limits ( see currently ⁇ NORM S 4035 or DIN 7880, Part 1: 19 ⁇ 1 mm for adults, and ⁇ NORM S 4036 or DIN 7880, part 2: 15 ⁇ 2 mm for children).
  • the object of claim 2 reduces the overall height of the jaw body, especially since part of the length of the compression spring is located within the sole holder.
  • the measure of claim 3 ensures that, on the one hand, the sole holder is pressed onto the ski boot with sufficient force, but that this pressure is not so great that there is a fear of influencing the pretension of the release spring.
  • the position of the sole holder in the jaw body is determined in a simple manner by the subject matter of claim 4.
  • Claim 5 describes the use of a cheek body according to the invention in a safety ski binding with a compensating lever, as described, for example, in AT-PS 368 396 and which enables compensation of the additional frictional forces occurring on the sole holder in the event of a backward fall.
  • a compensating lever as described, for example, in AT-PS 368 396 and which enables compensation of the additional frictional forces occurring on the sole holder in the event of a backward fall.
  • an elastic element is arranged between the sole holder and the compensating lever, but this is only used to enable a pivoting movement of the compensating lever without the sole holder changing its vertical position.
  • the elastic element does not influence the height of the release lever.
  • the arrangement of a coil spring is particularly favorable for manufacturing reasons.
  • the sole holder is secured against lateral pivoting.
  • Claim 7 expresses the fact that the measure according to the invention can also be used advantageously with heel cheeks.
  • the distance between the sole holder and the underside of the housing, which is automatically set by the ski boot via the helical spring, is essentially determined.
  • a front jaw is characterized in claims 12 and 13, in which the bolt which forms the pivot axis for the housing, as is also known, is held in the bearing block against axial displacement and in which the housing is guided on the bolt so as to be displaceable in the vertical direction is.
  • Fig. 1 is a vertical longitudinal central section through a first embodiment formed as a front jaw in the starting position and Fig. 2 is an associated partially sectioned plan view. 3 and 4, the cheek body is shown in a partially sectioned side view with a thin or thick shoe sole inserted.
  • 5 shows a further jaw body, likewise designed as a front jaw, in a vertical longitudinal central section.
  • Fig. 6 a third front jaw is shown in the longitudinal center section. This is shown in FIG. 7 in a partially sectioned side view with the shoe sole inserted.
  • Fig. 6a is a section on a larger scale along the line Vla - Vla in Fig.
  • FIG. 6 through a detail of the toe and Fig. 6b is a variant thereof.
  • 8 and 9 show a cheek body, which is designed as a heel holder, in a partially sectioned side view in the idle state and during the boarding process.
  • 10 and 11 or 12 and 13 vertical vertical sections through further front jaws according to the invention similar to FIGS. 1 and 3 are shown.
  • 14 is a top view of FIG. 12.
  • a jaw body shown in FIGS. 1-4 is designed as a front jaw and is designated 1 in its entirety. It has a housing 2 which can be fastened in a known manner to the top of a ski (not shown) by means of screws (not shown) and in which a support body 3 which is approximately angular in longitudinal section is arranged. Of this, one leg 3a is arranged substantially parallel to the top of the ski. The other leg 3b runs vertically to the top of the ski and carries at its upper end an axis 4 which runs in the direction of the ski and parallel to the top of the ski. On this axis 4, an angle lever 5 is mounted.
  • a vertical bore 5c is recessed, which is penetrated by a bolt 6, the head 6a of which rests on the leg 5a.
  • the lower end of the bolt 6 is guided in a bore 3c of the leg 3a.
  • the bore 3c is located in a cup-shaped bulge 3d of the leg 3a.
  • the lower end of the bolt 6 is provided with a thickening 6b, which limits the displacement of the bolt 6 and thus the pivot angle of the angle lever 5.
  • the bolt 6 passes through the stepped bore 7a of a sole holder 7, which rests on the bulge 3d of the leg 3a when the ski boot is not in use (see FIG. 1). Furthermore, the bolt 6 is surrounded by a coil spring 8, which is arranged with its lower end in the stepped bore 7a and with the other, upper end on the underside of the leg 5a, optionally with the interposition of a locking washer 9, which is supported in a groove of the bolt 6 engages. There is play between the locking washer 9 and the underside of the leg 5a, which allows the angle lever 5 to be pivoted.
  • the remaining structure 3a of the toe piece 1 is of a known type.
  • the leg 3a of the supporting body 3 carries two vertical axes 10 at a lateral distance from the vertical longitudinal center plane of the toe piece 1, on which lateral angle levers 11 are mounted, of which one leg for lateral support of the shoe sole 12a, 12'a one in the toe pieces 1 used shoe 12, 12 'is used (see FIGS. 3 and 4).
  • a trigger spring 13 extending in the longitudinal direction of the jaw 1 is accommodated in the housing 2.
  • the bias of the release spring 13 can be adjusted by means of a sleeve 14 with an internal thread.
  • This sleeve 14 is screwed onto the threaded section of a pull rod 15 which passes through the release spring 13 in the center.
  • the pull rod 15 carries a slide 17. On the pull rod 15, a pull to the ski tip is exerted by the release spring 13.
  • the slide 17 acts on each of the two side angle levers 11, and via this the angle lever 5.
  • Fig. 1 the toe 1 is shown before the ski boot is used.
  • the approximately wedge-shaped tapered tip of the shoe sole 12a or 12'a is inserted obliquely from above into the gap between the leg 3a of the support body 3 and the sole holder 7.
  • the ski boot 12 or 12 ' is depressed so that it rests with its shoe sole 12a or 12'a on the leg 3a or on a base plate 18 (see FIGS. 3 and 4).
  • the sole holder 7 is raised against the force of the coil spring 8 in accordance with the thickness of the shoe sole 12a or 12'a.
  • This position of the sole holder 7 is shown in FIG. 3 when using a ski shoe with a thickness h i of the shoe sole 12 and when using a ski shoe with a thickness h 2 of the shoe sole 12'a in FIG. 4.
  • the front jaw 1 'shown in Fig. 5 is very similar to that described first. It differs from this only in that the head 6'a of the bolt 6 'is mounted in the housing 2' itself, and that the release spring 13 'accommodated in the housing 2' only acts on the two lateral angle levers 11 ', which act on the side Bracket of the shoe sole are intended.
  • this design is somewhat simpler in structure than the one dealt with first, it has the disadvantage that it does not compensate for the frictional forces that occur backwards on the sole holder in the event of a fall.

It differs from this only in that the bolt 6" in the region of the half of its lateral surface facing away from the release spring 13 " is provided with ribs 6 "c which run normal to the pin axis and in the circumferential direction of the pin 6" and which are approximately crescent in plan view and which correspond to corresponding grooves 7 "b in the associated half of the approximately elliptical bore of the sole holder 7".
  • Fig. 6a illustrates on a larger scale the configuration of the ribs 6 "c of the bolt 6" and the grooves 7 "b of the sole holder 7". It should be noted that the sole holder 7 "can be moved in the vertical direction relative to the bolt 6".
  • the variant of a sole holder 7 "'according to FIG. 6b differs from the previously described embodiment in that the bolt 6 1v is flattened laterally following the ribs 6 1v c, and that the sole holder 7 IV has guides corresponding to the flats. As a result, the sole holder 7 IV is secured against lateral swiveling.
  • FIGS. 8 and 9 relate to a jaw body which is designed as a heel holder 30.
