    • A63C9/00—Ski bindings

Definitions

  • the invention relates to a ski binding according to the first part of claim 1.
  • the position body is thus held directly on the guide rail (called “base plate” in the publication) and secured against shifting during transport.
  • the fastening screws are held in bores in the base plate of this ski binding by radial projections.
  • screwing in is cumbersome in many cases; in the first case the under projections must be overcome by pressure, in the second case the screwing-in can only be done in sections because the screws with their threaded sections protrude considerably from the base plate before the screwing process.
  • ski binding which is already equipped with fastening screws during its manufacture, can be found in DE-C-2359489.
  • This ski binding has four bearing blocks, called “flanges” in the patent, which are arranged on a guide rail to be fastened to the ski, called “base plate” in the patent. There are holes in the flanges that run perpendicular to the top of the ski.
  • the jaw body itself is fastened on a base plate, in the patent "area designed as a sliding guide", which is guided between the bearing blocks so as to be adjustable and lockable.
  • Bush-shaped holding elements made of plastic, sheet metal or another deformable material are used in the bores of the bearing blocks. Then the fastening screws are screwed in, the holding elements being slightly deformed.
  • the mounting screws are longer than the height of the pedestals; thus they protrude with their upper ends over the bearing blocks before assembly and protrude somewhat under the plate with their lower ends.
  • This design has the disadvantage that the holding elements have to be manufactured separately and then inserted into the bores of the bearing blocks.
  • the known design is therefore expensive and time-consuming to manufacture.
  • each tube has a flange, the inner wall of which has a helical lip.
  • a funnel-shaped trough is formed above the curtain, which serves to hold the thread of the individual fastening screws.
  • each tube has at least two vertical slots at its lower end. To screw in the fastening screw, its head diameter is smaller than the inside diameter of the individual pipes.
  • This known embodiment has the disadvantage that an additional component, namely the cross handle with four tubes, must be used, furthermore that this component is designed as a one-way aid.
  • the use of the cross handle is too expensive for this purpose.
  • the individual fastening screws in the individual tubes must be operated, which manipulation is cumbersome.
  • the invention has for its object to provide a jaw for ski bindings, in which the screws required for attaching the jaws to the ski are reliably held in place in the base plate of the jaws before assembly without the use of additional holding elements.
  • this object is achieved according to the invention by the features of the characterizing part of claim 1.
  • the mounting screws can be inserted directly into the holes in the base plate before mounting the guide rail on the ski and can be fixed in the holes by means of an interference fit, these are reliably held in place in the holes during transport. This can be further supported if the walls of the bores are provided with a lateral slot, which provides a certain resilient mounting.
  • the fastening screws are screwed in, both a torque and an axial force are simultaneously applied to them, so that the heads of the individual screws also perform a screw movement. The two types of movement quickly overcome the friction at rest and each fastening screw is screwed into the ski through the associated hole in the guide rail.
  • the upper limit values can advantageously be used in the case of a base plate provided with side slots.
  • the measure of claim 4 ensures an elastic holder for the individual fastening screws through the base plate itself.
  • the feature of claim 5 ensures an unimpeded displacement of the base plate relative to the guide rail and at the same time avoids an inclined position of the fastening screws in their bores.
  • the feature of claim 8 has the purpose of preventing the ingress of snow and dirt into the base plate.
  • Fig. 1 is a side view of the ski binding, the base plate of which is drawn in section in the area of the fastening screws.
  • 2 and 3 are side views on a larger scale partly. in section through the base plate along the line II-II or III-III in Fig. 1.
  • Fig. 4 is a section along the line IV-IV in Fig. 1.
  • Fig. 5 shows a second embodiment in front view of the base plate .
  • a heel holder is shown as a ski binding, which is designated in its entirety with 1.
  • the heel holder 1 consists of a base plate 2 and of a known, known per se body 3, which is shown only schematically in FIG. 1.
  • the base plate 2 projects laterally beyond the cheek body 3 transversely to the longitudinal direction of the ski (see FIG. 4).
  • 4 stepped bores are cut out as bores, which widen downwards.
  • 4a is a constriction located at the upper end of the stepped bore 4.
  • the base plate 2 is guided on a guide rail 5, in which holes 6 are punched out in pairs, which serve for the passage of fastening screws 7.
  • the holes 6 are in cup-shaped, downwardly projecting lugs 8 of the guide rail 5. These lugs 8 are intended to receive the heads 7a of the fastening screws 7 when the guide rail 5 is already screwed onto the ski 9 by them.
  • the fastening screws 7 are preferably Phillips screws which have a conical threaded section 7b.
  • the length of the fastening screws 7 is shorter than the length of the individual stepped bores 4 between the constriction 4 a and the mouth on the underside of the base plate 2.
  • each fastening screw 7 rests with the end face of its head 7a on the constriction 4a of the stepped bore 4.
  • the region of the bore 4 adjoining the constriction 4a has a cylindrical section 4b and a conical section 4c adjoining this.
  • the fastening screw 7 is inserted from the underside of the base plate 2 with its head 7a ahead into the stepped bore 4.
  • the upper section 4b of the stepped bore 4 holds the cylindrical outer surface of the head 7a of each fastening screw 7 by friction, and the entire fastening screw 7 is located within the base plate 2.
  • the section 4b of the stepped bore 4 has a 0, 05-0.5 mm smaller diameter than the head 7a of the fastening screw 7.
  • the base plate 2 Before the screwing-in process, the base plate 2 is first brought into the position opposite the guide rail 5 in which the holes 6 are aligned with the stepped bores 4. In this position, the base plate 2 is held relative to the guide rail 5 by a not shown, known locking device. Then the guide rail 5 and the base plate 2 with the jaw body 3 existing unit placed on the ski 9 so that the fastening screws 7 are aligned with the holes 9a previously made in the ski 9.
  • a screwdriver is inserted into the cross slot of the fastening screw 7, and the fastening screw 7 is screwed into the hole 9a of the ski by rotating and axially compressing the friction of the screw head 7a against the wall of the stepped hole 4 (see FIG. 3).
  • the screw head 7a is located entirely below the underside of the base plate 2, in the present case in the cup-shaped extension 8, so that the base plate 2 can be moved along the guide rail 5 without being moved as soon as the locking device (not shown) is released .
  • the second embodiment according to FIG. 5 differs from that previously described in that the base plate 2 'is provided with slots 2'a in the region of the stepped bores 4'. Through these slots 2'a an additional suspension for holding the fastening screws 7 is brought about.
  • that section of the stepped bore 4 in which the screw head is held can have a diameter that is up to 0.5 mm smaller than the head of the fastening screw 7.
  • the invention is not limited to the embodiment shown in the drawing and described above. Rather, various modifications thereof are possible without leaving the scope of the invention.
  • the head of the fastening screw does not have to be held with its entire surface by the wall of the bore during the holding process. Rather, it is sufficient if
  • three ribs for example, are arranged uniformly distributed on the circumference of the bore and extend in the direction of the bore axis.
  • Another solution is characterized in that, below the step of the stepped bore, an annular bead protrudes inwards according to the invention, which comes to rest on the cylindrical surface of the head of the fastening screw when it is to be held.
