Definitions
- the invention relates to a ski brake according to the preamble of claim 1.
- a ski brake is known, for example, from the Austrian patent application 1243/87 (Austrian patent number).
- a rigid intermediate member is articulated on the angled end sections of two multi-angled wire brake arms accommodated in the actuation pedal, said intermediate member having a cylindrical sleeve and an extension adjoining it, which extension in the ready position of the ski brake on a support surface of the base plate against the force of one angled end portions of the connecting spring connecting the wire brake arms is supported.
- This ski brake has indeed been proven, but it has been shown 'that certain unfavorable circumstances may hinder the pivoting movement of the brake arms from the ready position into the braking position.
- the brake arms may be bent due to the rough operation, or it is possible that the width of the skis is larger than usual. Then it can happen that at least one brake arm gets stuck on the side edge of the ski and the braking effect is reduced or switched off.
- the invention has set itself the goal of improving this known ski brake in such a way that the pivoting of the brake arms into the ready position takes place reliably even under unfavorable conditions.
- the base plate in its section supporting the support surface has a continuous groove-shaped clearance extending approximately over the entire width of the support surface, arranged approximately parallel to it, the support surface can recede or spring back if necessary.
- the design according to the characterizing features of claim 3 enables the designer to choose the spring action as required.
- the sprung support is realized in the intermediate member. This can be achieved through a recess. This also simplifies the construction of the base plate.
- FIG. 1 is a vertical longitudinal central section through the ski brake in the braking position
- FIGS. 2 and 3 show a detail from FIG. 1
- FIG. 4 shows the base plate of the ski brake in a top view.
- the ski brake shown in FIGS. 1 to 4 is designated 1 in its entirety. It has a base plate 2 with a base 2a, which is attached to a ski 10, for example by means of only indicated screws 3.
- Fig.l is also a part of a mounting plate 11 can be seen, which serves as a holding element for a ski binding part, not shown here, and which is screwed together with the base 2a of the ski brake 1 on the ski 10.
- At the base 2a are upwardly projecting strip-shaped side parts 2b which run in the longitudinal direction of the ski brake 1.
- a transverse axis 4 is fastened, on the one hand an actuating pedal 5 and on the other hand two as leg springs 6 trained springs are stored.
- the actuation pedal 5 has a stop 5a and two laterally bent tabs 5b.
- funnel-shaped transverse bores 2c are recessed in the side parts 2b of the base plate 2, in which two wire brake arms 7, shown in dash-dotted lines in the drawing, are pivotably mounted with their transverse sections 7b.
- Each wire brake arm 7 has a section located outside the base plate 2, which has a plastic encapsulation, which is only indicated in the drawing and serves as a brake blade, and is hereinafter referred to as the brake mandrel 7a, the section 7b already mentioned, a section adjoining this 7c, which runs approximately parallel to section 7a, and an end section 7d connected to section 7c at an obtuse angle.
- the end sections 7d of the two wire brake arms 7 are directed towards one another and are connected to one another by a connecting spring 8.
- the end sections 7d of the ' wire brake arms are mounted in the operating pedal 5 in a known and therefore not described manner.
- An intermediate member 9 is placed on the connecting spring 8, which is designed here as a screw spring, and has a cylindrical sleeve 9a with an extension 9b adjoining it.
- the extension 9b is subdivided into a first section 9g facing the sleeve 9a and a section 9h adjoining it, the second section 9h being angled with respect to the first section 9g.
- the extension 9b of the intermediate member 9 is approximately U-shaped in plan view, the legs of the U-s being formed by the second section 9h. The free ends of the legs have inward projections 9i.
- Attached to the base plate 2 is a section running in the vertical longitudinal center plane, directed away from the transverse axis 4 and designed as a bearing block 2g
- Cross-section is approximately I-shaped.
- Two grooves 2h of the bearing block 2g serve to guide the projections 9i of the intermediate member 9.
- a support surface 2f is formed on the end face of the bearing block 2g.
- a groove-shaped relief 2i is formed on the underside of the bearing block 2g.
- the longitudinal center plane of the groove-shaped free position 2i runs approximately parallel to the support surface 2f.
- the groove-shaped relief 2i extends over the entire width of the bearing block 2g and in the height direction at least up to the upper end of the support surface 2f, preferably beyond.
- the bearing block 2g is designed so as to be slidable relative to the upper side of the ski 10, at least in the area carrying the support surface 2f.
- Fig.l the ski brake 1 is shown in its braking position.
- the projections 9i of the intermediate member 9 are located at a distance from the ski surface in the upper section of the groove-shaped relief 2i.
- the interaction of the intermediate member 9 with the bearing block 2g and in particular with the support surface 2f enables precise control of the movement sequence.
- certain external conditions such as slightly bent brake mandrels or skis that are too wide, require a deviation from this quasi "preprogrammed" movement sequence in order to ensure the overall function of the ski brake.
- the bearing block 2g of the base plate 2 can be slightly deformed in the region of the groove-shaped relief 2i by the action of the intermediate member 9. This situation is shown in Figures 2 and 3.
- the support surface 2f backs off in the direction of the transverse axis 4.
- This retraction of the support surface .2f gives the intermediate member 9 greater freedom of movement, which also increases the mobility of the wire brake arms 7.
- the setting of the actuating pedal 5 and the movement of the wire remsarme 7 from the ready position to the braking position can be done reliably in any case.
- two or more narrow grooves are arranged parallel to one another instead of a single groove-shaped exemption.
- either the support area of the crossbar can be made of a suitable elastic material or it is also possible to provide an elongate recess in the intermediate member following and parallel to the crossbar. In both cases, the base plate can then be designed in a simplified manner without a groove-shaped exemption.

Abstract
Un frein de ski (1) comporte deux bras métalliques (7) montés en pivot dans une plaque de base (2). Lesdits bras peuvent être amenés dans leur position de fonctionnement par enfoncement d'une pédale d'actionnement (5) qui pivote à l'encontre de la force d'un ressort de relevage (6). Les sections terminales (7d) des bras métalliques (7) sont logées dans la pédale d'actionnement (5) et reliées par un ressort de liaison (8) auquel est articulé un élément intermédiaire rigide (9). Un prolongement (9b) de l'élément intermédiaire (9) est abouté contre une surface d'appui (2f) de la plaque de base (2). Afin d'assurer un fonctionnement fiable même dans des conditions difficiles, et d'empêcher les bras métalliques (7) de rester accrochés sur le dessus ou sur les bords latéraux du ski (10)), un support élastique est prévu entre la région de la plaque de base (2) qui porte la surface d'appui (2f), et la nervure transversale (9k) de l'élément intermédiaire.A ski brake (1) has two metal arms (7) pivotally mounted in a base plate (2). Said arms can be brought into their operating position by depressing an actuation pedal (5) which pivots against the force of a lifting spring (6). The end sections (7d) of the metal arms (7) are housed in the actuation pedal (5) and connected by a connecting spring (8) to which a rigid intermediate element (9) is articulated. An extension (9b) of the intermediate element (9) is abutted against a bearing surface (2f) of the base plate (2). In order to ensure reliable operation even under difficult conditions, and to prevent the metal arms (7) from remaining hung on the top or on the side edges of the ski (10)), an elastic support is provided between the region of the base plate (2) which carries the bearing surface (2f), and the transverse rib (9k) of the intermediate element.
