Description

The present invention relates to a stop device, particularly usable for skis.
Numerous stop devices for skis, also known as ski-stoppers are currently known.
Such devices usually consist of two arms having an end provided with a stop skid interacting, in use, with the snow and an end directly associated with a small plate.
Said small plate is pivoted to a main plate which is rigidly associated with the ski, and interacts with a spring which tends to impart thereto a rotation with respect to said main plate so that said skids make contact with the snow.
While skiing, the skier keeps the small plate in contact with the main plate since the sole of the boot makes contact with the former, usually at the heel region.
In such conditions the arms are arranged either upwardly or laterally with respect to the ski so that the skids do not interact with the snow.
A device is also known which, in order to allow the positioning of the skids above the upper surface of the ski, is provided with arms which are co-planar with respect to the small plate, its ends associated therewith being bent to form a V in the direction of the end opposite to the one provided with the skids.
Though such devices allow to stop the ski if the skier is no longer resting with the boot on the small plate, they have some disadvantages, such as their structural complexity and the not optimum manner in which said arms interact with the small plate.
The aim of the present invention is therefore to eliminate the disadvantages described above in known types, by devising a stop device for a ski which features considerable simplicity in structure and in operation.
Within the scope of the above described aim, an important object is to provide a device which has a very compact structure.
Not least object is to obtain a device which is reliable, has modest costs and can be manufactured with ordinary machinery.
The aim and the objects described above, as well as others which will become apparent hereinafter, are achieved by a stop device, particularly for skis, comprising two arms, each arranged at rest at one side of a ski and each having at one end a stop skid interacting with the snow, characterized in that it comprises a main plate, associable with said ski and a box-like element associable with an end of said main plate, on said box-like element and on said main plate there being provided, specularly with respect to the longitudinal middle plane of both element and main plate, first and second half-seats respectively defining a first transverse seat for a pivot for the pivoting of a small control plate and of an elastically deformable element interposed between said main plate and said small control plate, and a second seat, inclined with its top in the direction of the longitudinal middle axis of said main plate, for a complementarily shaped intermediate portion of said arms, the end of said arms being interposed between said small control plate and said elastically deformable element, said elastically deformable element imparting to said arms and to said small control plate a rotation which arranges said skids in contact with said snow.
Advantageously, said planar main plate constitutes a base for a fastening adapted to associate said boot with said ski.
Further characteristics and advantages of the invention will become apparent from the description of a particular embodiment, illustrated only by way of non-limitative example in the accompanying drawings, wherein.

fig. 1 is an exploded view of the stop device according to the invention;
fig. 2 is a partial view, along a longitudinal middle cross section plane, of the device at rest and in operating conditions;
fig. 3 is a view of the structure in partial cross section along a plane parallel to that of arrangement of said main plate;
figs. 4 and 5 are perspective views of the device respectively in resting and operating conditions;
fig. 6 is a section view along the line VI-VI of Fig. 3.

With reference to the above described figures, the reference numeral 1 indicates the stop device or ski stopper particularly usable for skis 2.
Said ski stopper comprises two arms, indicated by the numerals 3a and 3b, specular to one another and each substantially consisting of a metallic rod provided at one end with a skid, indicated by the numerals 4a and 4b.
At the other end, each of said arms is provided with a flattened portion, indicated by the numerals 5a and 5b; proximate thereto, each arm is shaped so as to have a first and a second portion, respectively indicated by the numerals 6a, 6b and 7a, 7b, inclined at counterposed angles so as to arrange the two ends of each arm approximately on the same plane.
The ski stopper 1 is also composed of a main plate 8 associable with the upper surface 9 of the ski 2 and having a width which is smaller than that of the latter.
A box-like element 12 is associable with the end 10 of said plate 8 which faces towards the rear end of the ski by known means such as for example screws 11, and is provided with two lateral shoulders 13a and 13b.
First half-seats are provided in said main plate 8 and in said shoulders 13a and 13b specularly with respect to the longitudinal middle plane of the ski.
Said half-seats respectively consists of a pair of small laterally protruding blocks, indicated by the numerals 14a and 14b, on each whereof is provided, transversely with respect to the main plate 8, a first recessed portion 15, and of a hole 16 provided transversely with respect to the shoulders 13a and 13b at the level of said recessed portion
Said first half-seats define a first seat for a pivot 17 for the pivoting of a small control plate 18 and for an elastically deformable element 19.
The control plate 18 is in fact provided with two small arms 20, accommodated within the box-like element 12 and provided with a hole 21 for the pivot 17.
The elastically deformable element 19 consists of a spring having two lateral arms 22 bent so as to form a central eyelet 23, which is interposed between the main plate 8 and the lower surface 24 of the small control plate 18, the ends of the spring being arranged between two raised portions 25 projecting from the plate 8 specularly with respect to the longitudinal middle plane of said plate.
Second half-seats are also provided at the surfaces of contact between said main plate 8 and said shoulders 13a and 13b specularly to one another and with respect to the longitudinal middle plane of the ski.
Said second half-seats are arranged inclined with respect to the plane of the plate 8 in the direction of its longitudinal middle axis and each consists of a second recessed portion 26 which affects, in the first case, both a region of the small blocks 14a and 14b adjacent to said first recessed portion 15 in the direction of the tip of the ski, and the surface of the plate 8.
Each of said recessed portions 26 constitutes a second seat in which the first portion 6a or 6b of the arm 3a or 3b can be arranged, ensuring that the lateral arm 22 of the spring is arranged above said first portion and that the central eyelet 23 of the latter is made to pass below the second portion 7a and 7b.
The use of the stop device is therefore the following: at rest, the spring locates the small control plate 18 as illustrated in fig. 5, that is to say raised with respect to the plate 8.
In such position the skids 4a and 4b are arranged below the plane of the sole 27 of the ski 2 and therefore in such a condition as to interact with the snow.
In the phase in which the skier places the heel 28 of the boot 29 on the small control plate 18, the latter rotates with respect to the pivot 17 and the spring is loaded.
Simultaneously, the arms 3a and 3b are made to rotate about an axis which coincides with that of the first portions 6a and 6b, causing them to position themselves as illustrated in fig. 4, that is to say with the skids 4a and 4b arranged to the side of the upper surface 9 of the ski 2.
The inward motion of the arms is thus achieved by means of their rotation on inclined counterposed planes which are symmetrical with respect to the longitudinal axis of the ski.
Naturally, the variation of the inclination imparted to each recessed portion 26, and therefore consequently to the first portions 6a and 6b of the arms 3a and 3b, allows to increase or decrease the possible inward motion of the skids 4a and 4b above the ski 2.
In order to further increase the inward motion of the skids it is also possible to incline each second recessed portion 26 also with respect to the longitudinal middle axis of the plate 8 such as to not arrange it perpendicular to said axis.
In such a case, a combined action is achieved due to the two inclinations imparted to the recessed portions 26.
It has thus been observed that the invention achieves the intended aim and objects, having a considerable structural and operative simplicity.
Moreover, due to the reduced dimensions and to the limited number of parts, the invention is reliable and has extremely modest costs.
Said reduced dimensions also allow to consider the stop device as an integral element of a fastening associated with the ski; for example, the plate 8 may constitute a base for a fastening as disclosed in US Patent Application No. 07/078,934 filed on July 27, 1987 by the same Assignee.
Naturally, the materials and the dimensions of the individual components, as well as the angles of the second recessed portions with respect to the plane of arrangement of the plate and with respect to its longitudinal middle axis may be any according to the specific requirements.
