DESCRIPTI~)N
This invention relates to a fastener for a ski board~
incorporating a device for adjusting its angular position on the ski board~
It is known, in relation to downhiLl skiing on so~called "ski boards" or "monoskis", that a basic requirement is that the set of each ski boot relatively to the board, whereon the boots are held securely by suitable fasteners or binders, should provide for best performance and greatest comfort in the sport practice, with due consideration for the characteristics of the course, the type of downhill race, the quality of the snow and snow mantle, etc., and above all, for the ski-boarder's features and build~
Such a requirement has been met heretofore by setting each fastener angularly on the ski board for utmost effectiveness prior to permanently securing it thereon.
However, after the best angular setting has been selected for each fastener and the fasteners secured on the board, the setting is bound to require alteration each time that at least one of the conditions for which it had been selected changes.
Conventional design fasteners are so structured as to ;nvolve lengthy and somewhat laborious, if not downright difficult, operations 7n order to achieve a desired angular setting therefor.
It is a primary ob~ect of this invention to overcome such difficulties by providing a fastener for ski boards which incorporates a device for adjusting its angular setting and locking it to the board in the seLected angular position, and has such construction and performance characteristics as to .
~ 3 ~
make for easy and quick manipulation of the fasteners and significant reliability.
These and other objects to become apparent from the ensuing detailed description are achieved by a fastener for ski boards being of a type whirh comprises a plate for fixedly holding a ski boot thereon, and a device for setting said plate angularly and locking it to the ski board, and characterized in that said device comprises:
a cylindrical bore going through said plate and having at least two coaxial sections with different diameters adapted to form an annular shoulder therebetween;
a cylindrical body engaged slidably within said bore and being formed coaxially, at one end thereof, with an annular flange adapted to bear on said annular shoulder;
a face dog clutch formed circumferentially between said flange and said annular shoulder; and a pressure member supported on said ski board and arranged to act on said cylindrical body to releasably lock i~ to the board under a condition of engagement of said flange with said annular shoulder.
The features and advantages of a fastener for ski boards according to the invention will be more clearly understood by : having reference to the following detailed description of an ~; embodiment thereof, to be taken in conjunction with the accompanying illustrative and non-limitative drawings, where:
: Figure 1 is an exploded perspective.view of a fastener : for ski boards according to this invention;
Figures 2 and 3 are cross-sectional views of a detail of the fastener shown in Figure 1, under two different operating conditions thereof;
~ 3 ~
Figure 4 shows a detail of Figure 3; and Figure 5 is an exploded perspective view, drawn to an enlarged scale, of a further detail of the fastener shown in Figure 1.
With reference to the drawing views, generally indicated at 1 is a fastener or binder for a ski board 2, in accordance with th;s invention. Said fastener 1 comprises an elongate plate 3 adapted to fixedly hold a ski boot (not shown) thereon.
The plate 3 is through-penetrated by a cylindrical bore 4 which has two coaxial sections, 5 and 6, with different diameters, defining an annular shoulder 7 therebetween.
- A cylindrical body 8 engages slidably within said bore 4 and is provided coaxially, at one end thereof, with an annular flange 9 bearing on the annuLar shoulder 7 in said through~going bore 4.
Advantageously, the cylindrical body 8 has its outside diameter dimension substantially equal to the inside diameter of the section 6 of said through-going bore 4, while the outside diameter of the annular flange 9 is substantially the same as the inside diameter of the section 7 -of said bore. In this way, the axial movements of the cylindrical body 8 within the through-going bore 4 can be guided.
The flange 9 is formed circumferentially with a radial toothing 9a, while the annular shoulder 7 is formed circumferentially with a corresponding radial toothing 7a. The toothings 7a and 9a jointly form a face dog clutch between the flange 9 and the annular shoulder 7.
A socket 10 having a rectangular cross-sectional shape is formed in the cylindrical body 8 with slots 12, 13 cut through 1 3 ~
its bottom 11 at the short sides of said socket. By virtue of these slots, the body 9 can be fitted over a pair of identical, parallel posts 14, 15 which project upwards from a base 16 conventionally attached to the board 2.
Ins;de said socket 10, the posts 14 and 15 on the base 16 carry a pin 17 about which the camming end 18 of a lever 19 is pivoted eccentrically.
gy means of this lever 19, the body 8 can be driven axially into the through-going bore 4 against the bias of spring means 20 to engage the face dog clutch between the flange 9 of said body and the annular shoulder 7 of the plate 3, whiLe locking at the same time this plate to the board 2, as explained hereinafter.
An elongate channel-like seat 21 is formed in the rearward region of the plate 3 which has a substantially rectangular cross-sectional shape. A slot 22 ~Figure 5) is cut axially through the bottom of this seat 21 and defines two parallel, side portions 23, Z4 on said bottom provided with respective sawtooth serrations 25 and 26.
Indicated at 27 is a U-shaped metal bracket which straddles the portion 3a of the plate 3 from below. The wings 28~ 29 of said bracket 27 are in substantial contact with the longitudinal sides of said portion 3a, thereby the movements of the bracket 27 along this portion of the plate 3 can be substantially guided.
Attached to the bracket 27 are one or more tensioning cables 30 for securely holding the heel portion of a ski boot (not shown) to be positioned on the plate 3 and securely held thereby.
The bracket 27 has a pin 31 at a middle lo~ation thereon ~ .
1 3 ~ 3 ~
which extends ins;de the seat 21 through the slot 23 in the latter.
A small plate 32 fits slidably on the pin 31 the bottom wall (or wall Facing the bottom of the rectangular seat 21) whereof is provided with at least one crosswise tooth 32a intended for engagement with the aforementioned serrations 25 and 26.
The pin 31 carries at the top a cross-pin 33 lying transversely to the rectangular seat 21, which cross-pin has the tightening cam-shaped end 34 of an actuation lever 35 for the plate 32 pivoted thereon.
The movements of this plate 32 toward and away from the bottom of the rectangular seat 21 are resisted by a spring means 36 for which the pin 31 provides a guide.
By suitable operation of the lever 35, the plate 32 can be locked to the bottom of the seat 21 by engaging its teeth with the serrations 25 and 26 on said bottom. As a result, the bracket 27 will become locked at a position selected to develop a desired tension for locking the heel of a ski boot to the plate 3.
To adjust the angular sett;ng of the inventive fastener 1, one should proceed as follows.
By operating the lever 19 so as to shift ;t angularly about the pivot pin 17, thereby the handgrip of said lever is brought out of the socket 10 in the cylindrical body 8, the pressure applied to this body by the camming end 18 of said lever is released. Consequently to this, the action of the springs 20 will prevail on the cylindrical body 8 and cause the toothings 7a and 8a (on the flange 9 of said cylindrical .
~ 3 ~
body 8 and on the annular shoulder 7 of said plate 3) to become disengaged as had been previously engaged dog clutch fashion.
Thus, the plate 3 is released for angular adjustment on the board 2 abcut the axis of the cylindrical body 8.
On a selected angular setting being attained, the dog clutch is re-engaged between the cylindrical body 8 and the plate 3 by means of the lever 19, and the plate 3 is at the same time locked to the board 2.
It may be appreciated that the above-described opera~;ons can be carried out quickly and easily, and that the angular setting and locking of the fastener 1 for the board 2 can be accomplished and retained over time in a most reliable manner.
The invention as herein disclosed is susceptible to many changes and modifications, well within the capability of a skilled person in the art, without departing from the true scope of the invention as set forth in the appended claims.
Furthermore, the ski boot bearing and holding plate 3 may form a "sole" for a shell or enclosure, to be provided with suitable conventional lacing and/or tightening arrangementsr which would be shaped, sized and constructed to accommodate a ski boot therein.

With reference to the drawing views, generally indicated at 1 is a fastener or binder for a ski board 2, in accordance with th;s invention. Said fastener 1 comprises an elongate plate 3 adapted to fixedly hold a ski boot (not shown) thereon.
The plate 3 is through-penetrated by a cylindrical bore 4 which has two coaxial sections, 5 and 6, with different diameters, defining an annular shoulder 7 therebetween.
- A cylindrical body 8 engages slidably within said bore 4 and is provided coaxially, at one end thereof, with an annular flange 9 bearing on the annuLar shoulder 7 in said through~going bore 4.

An elongate channel-like seat 21 is formed in the rearward region of the plate 3 which has a substantially rectangular cross-sectional shape. A slot 22 ~Figure 5) is cut axially through the bottom of this seat 21 and defines two parallel, side portions 23, Z4 on said bottom provided with respective sawtooth serrations 25 and 26.
Indicated at 27 is a U-shaped metal bracket which straddles the portion 3a of the plate 3 from below.
