ADJUSTINGDEVICE FOR A SKI-BINDING Ski-bindings are required to be adapted to different ski-boot sizes. Thus for example the heel tightener or a heel locking device should be arranged on the ski or on a release plate so as to be adjustable, or the toe-clamps and the front sole holders should be laterally and vertically adjustable and if there is a release plate, this latter may be composed of two parts that are longitudinally movable with respect to one another. In the prior known adjusting devices used to this end, threaded holes are usually provided in one adjusting part for receiving fixing bolts, the adjustment being effected after loosening of the screws by mutual shifting of the parts. These devices are generally complicated and the threaded holes provided in one adjusting part must be made especially and, if the adjusting part consists of light metal or plastic material, are easily damaged.
It is an object of this invention to provide an adjusting device for a ski-binding which obviates these disadvantages.
According to the invention the adjusting device comprises two parts adjustable relatively to each other, one of said parts having a smooth-walled bore and the other part including at least one plug member guided in said bore, said plug member having a threaded portion, said one part being provided with a recess opening into said bore, and a screwnut held in said bore and engaging the threaded portion of said plug member, whereby relative rotation between said nut and said plug member causes relative adjustment of said two parts.
The screwnut may either be nonrotatably held in the associated recess and adjustment may be effected by rotation of the plug member, or the nut can also be rotatably mounted in the recess and be knurled on its periphery, so that the adjustment may be effected by rotating the nut.
An additional possibility of adjustment may be provided in that the adjusting part having the plug member is pivotable about the axis of the bore.
For an additional rough adjustment, a plurality of recesses may be provided at a distance from one another in one adjusting part for receiving the screwnuts.
The invention will now be described with reference to the annexed drawings in which:
FIG. 1 is a plan view of an adjusting device for a ski-boot heel locking means.
FIG. 2 is a view in elevation of the adjusting device shown in FIG. 1.
FIG. 3 is a plan view of another embodiment of an adjusting device for heel locking means.
FIG. 4 is a plan view of an adjusting device for a sole holder at the front end of the ski-binding.
FIG. 5 is a view in elevation of the adjusting device shown in FIG. 4.
FIG. 6 is a plan view of an adjusting device for sole holding aws.
FIG. 7 is a plan View of an adjusting device for sole holder members.
FIG. 8 is a view in elevation of FIG. 7.
FIG. 9 is a plan view of an adjusting device for the longitudinal adjustment of a release plate.
Referring now to FIGS. 1 and 2, the adjusting device shown is combined with a safety ski-binding, wherein a plate 2 is secured to the ski l in the region of the ski-boot heel by means of screws 3. A conical lug 5 of a release plate 4 of the ski-binding engages in a conical recess 5' of this plate. The plate 4 is provided with four smooth transverse bores 6, and each bore 6 is provided with two transversely spaced cylindrical recesses 7, opening from the top into the bore. Discs 8 are insertable as desired into these recesses. The discs 8 serving to provide screwnut means may consist of a material other than that of the plate 4 and each disc is provided with a diametrical threaded bore 8'. Into either end of one of the bores 6 there is inserted a plug member or arm 9' of a rectangularly bent adjusting bolt 9 and screwed by its threaded end 9" into the threaded bore of the disc 8 inserted in the recess 7. On the other, likewise threaded arm 9" of the adjusting bolt 9 is screwed a threaded sleeve I0 which cooperates with a known heel locking device (not shown) of the ski-binding. By rotating the threaded sleeve 110, it is possible to make a fine adjustment of the heel locking device. When the sleeve 10 has been released from the arm 9", the adjusting bolt 9 can be turned about the axis of the bore 6 and the adjusting bolt is thereby laterally adjusted with respect to the slti.'The arm 9' of each adjusting bolt 9 may also be completely screwed out of the disc 8 and, after placing the disc 8 into another recess 7, may again be screwed into the disc 8; inthis manner, a rough longitudinal adjustment of the heel locking device is obtained. As may further be seen from FIG. 2, the adjusting bolt 9 is pivotable about the axis of the transverse bore 6 and may therefore be adjusted to any inclined position.
The embodiment of the adjusting device according to FIG. 3 is similar to that of FIGS. l and 2. However, it differs from the latter in that, instead of the cylindrical recesses 7, prismatic recesses Ill are provided in the bores 6, and instead of the discs 8, threaded nuts 12 are provided, which are knurled on the periphery, in order that they may easily be turned by hand. The lateral adjustment of the adjusting bolts 9 and removal of the bolts from one bore 6 to place them into another bore is effected here by rotation of the nuts 12, so that it is no longer necessary first to unscrew the sleeve It) for adjusting purposes.
The adjusting device shown in FIGS. 4 and 5 serves to adjust the level of a sole holder carried by the front end of a release plate 14 of a safety ski-binding, the plate being secured to the ski 13. On the upwardly turned front end of the plate 14, two pins 16 are guided in two vertical bores 15', said pins being fixed to a sole holder plate 17. Each of the pins to has a threaded part 116 on which a toothed threaded nut 18 is screwed, which is held in a corresponding recess in the end part 15. By rotating the two threaded nuts 18, the sole holder plate 17 may be adjusted in vertical direction and thereby adapted to the thickness of the sole of the ski-boot. Furthermore, a resilient bolt 19 of a locking mechanism 20 of the safety ski-binding cooperates in a manner known per se with the end part 15.
FIG. 6 shows an adjusting device for the lateral or sideward adjustment of holding jaws 22 in a release plate 2B. This latter has a transverse bore 211' engaging at either side of the plate a pin-shaped, threaded stem 22' of a jaw 22, having at each end a jaw portion 22" bent upwardly at right angles. The release plate 211 is provided with two recesses 24 opening into the transverse bore 21'. Each recess holds a knurled threaded nut 23 screwed onto the threaded part 22' of the jaw stem 22'. By rotating the nuts 23, the two jaws 22 may be laterally adjusted independently of one another.
FIGS. 7 and 8 represent an adjusting device for ski-boot sole holding members. Two lateral adjusting bolts 26 each have a threaded stem portion 26 engaging into a transverse bore 25' of a release plate 25. The stems 26 are screwed into screwnuts 27 lodged in recesses 28 in the plate 25. A stem portion 26 of the bolt 26 is bent up at right angles and slidably engages one end 29' of a hollow holding link 29. The other end 29" of the link 29 slidably engages one arm 30 of a further adjusting bolt 30 which is bent at right angles. The other end 30" of the bolt 30 is screw threaded and engages a vertical bore 25" in a front lug 31 of the release plate 25. A screwnut 32 is screwed to the end 30", this nut being held in a recess 33 of the lug 311. The holding rods 29 serve to engage over the sole of a ski-boot, and they may be vertically adjusted by rotating the nuts 32, and laterally by rotating the nuts 27, for the purpose of adapting the rods to the size of the boot.
FIG. 9 shows an adjusting device for altering the length of a release plate, which consists of a main portion 34 and a front end portion 35. Two pins 36 are fixed to this end portion 35, which are threaded and which engage in smooth bores of the main portion 34. A nut 37 is screwed on the threaded part of each pin 36, the nuts being held in a corresponding recess 38 of the main portion 34, so that by rotating the nuts 37, both portions 34 and 35 may be relatively moved towards and away from each other.
