Definitions

  • the invention relates to a ski brake, with a base plate which can be fastened to the upper surface of a ski, with at least one between its two ends both about a first axis running transversely to the longitudinal direction of the ski and approximately parallel to the upper ski surface, and also about a second axis running approximately perpendicular to the upper ski surface Brake lever pivotally mounted on the base plate, one end of which projects freely, with a tread plate connected to the other end of the brake lever, which resiliently moves into a braking position remote from the base plate, in which the free end of the brake lever projects under the lower surface of the ski.

Abstract

The ski brake comprises a base plate (3) on which are supported two brake levers (15, 17) between their two ends via a crossed linkage (27) pivotably about two mutually perpendicular axes. Crank arms (35) opposite the free ends (33) of the brake arms are connected in articulated manner with a foot pedal (41) whose opposite end in the lengthwise direction of the ski is linked to guidance means (45) which are guided upon the base plate (3) slideably in the lengthwise direction of the ski against the pressure of a pretensioning spring (61). In the braking position, in which the free ends of the brake levers (15, 17) project below the ski runner surface, the pretensioning force of the spring (61) is absorbed by a bearing surface (57) of the base plate (3). In the ready position, in which the foot pedal (41) is pressed down upon the base plate (3) the free ends (33) of the brake levers (15, 17) are lifted above the ski. A slide block (67) slides the foot pedal (41) via its inclined sliding surface (69) away from the crossed linkages (27) upon approaching the ready position, whereby the free ends (33) of the brake levers (15, 17) are pivoted inwardly toward the middle of the ski. During the inward pivoting movement and in the ready position, the slide block (67) likewise transfers the pretensioning force of the spring (61) to the base plate (3), so that similarly to the braking position also in the ready position the linkages of the brake levers (15, 17) are unloaded.

Eine Skibremse dieser Art ist aus der DE-OS 24 12 623 bekannt. Die Skibremse umfaßt eine U-förmige Grundplatte, an der ein einstückiger, aus Federdraht gebogener Bremsbügel um zur Skioberfläche parallele Querachsen schwenkbar gelagert ist. Als Gelenkwellen dienen schräg zur Skilängsrichtung verlaufende Abkröpfungen der Schenkel des Bremsbügels, die durch Loslageröffnungen der Schenkel der Grundplatte hindurchtreten. Die Abkröpfungen sind so geformt, daß sie den Bremsbügel normalerweise in seiner Bremsstellung halten, in der die freien Enden seiner Schenkel unter die untere Skifläche ragen. An dem in dieser Stellung von der Grundplatte entfernten Quersteg des Bremsbügels ist eine Trittplatte befestigt, die das Niederdrücken des Bremsbügels erleichtert. In der niedergedrückten Bereitschaftsstellung sind die freien Enden des Bremsbügels etwa auf die Höhe der oberen Skifläche angehoben. Durch das Niederdrücken der Trittplatte auf der Bremsstellung in die Bereitschaftsstellung wird der Bremsbügel, insbesondere dessen-Abkröpfungen, elastisch deformiert, was den Bremsbügel federnd in die Bremsstellung vorspannt.A ski brake of this type is known from DE-OS 24 12 623. The ski brake comprises a U-shaped base plate on which a one-piece brake bracket bent from spring wire is pivotably mounted about transverse axes parallel to the ski surface. Cranks of the limbs of the brake bracket, which run obliquely to the longitudinal direction of the ski and which pass through floating bearing openings in the limbs of the base plate, serve as drive shafts. The bends are shaped so that they normally hold the brake bracket in its braking position, in which the free ends of its legs protrude below the lower ski surface. On the transverse web of the brake bracket, which is removed from the base plate in this position, a step plate is fastened which facilitates the depression of the brake bracket. In the depressed standby position, the free ends of the brake bracket are raised to about the height of the upper ski surface. By depressing the tread plate on the braking position to the ready position, the brake bracket, in particular its cranking, is elastically deformed, which resiliently biases the brake bracket into the braking position.

An den freien Enden der Schenkel der Grundplatte sind Schrägflächen vorgesehen, die mit entsprechenden Schrägflächen der Trittplatte bei Annäherung an die Bereitschaftsstellung zusammenwirken und den Bremsbügel über dessen Abkröpfungen strecken. Die freien Enden der Schenkel des Bremsbügels legen sich dadurch zangenartig an die Seitenkanten des Skis an.At the free ends of the legs of the base plate, inclined surfaces are provided, which cooperate with corresponding inclined surfaces of the tread plate when approaching the standby position and stretch the brake bracket over its offset. The free ends of the legs of the This means that brake brackets rest like pliers on the side edges of the ski.

Bei der bekannten Skibremse sind die Grundplattenlager des Bremsbügels relativ großen mechanischen Belastungen ausgesetzt. Die Loslageröffnungen der Schenkel der Grundplatte müssen nicht nur die beim elastischen Verformen des Bremsbügels zur Erzeugung der Rückstellkraft auftretenden Kräfte aufnehmen, sondern werden zusätzlich durch die beim Strecken des Bremsbügels in der Bereitschaftsstellung auftretenden Kräfte belastet. Die relativ schmalen Auflageflächen der Loslager werden leicht deformiert, womit das Einschwenken der freien Enden der Bremsarmschenkel in der Bereitschaftsstellung nicht mehr gewährleistet ist. Darüber hinaus ist der Schwenkwinkel, um den die freien Enden zur Skimitte hin eingeschwenkt werden können, relativ klein. Da bei der bekannten Skibremse weiterhin der Bremsbügel durch Eigenspannung in die Bremsstellung vorgespannt wird, kann es zu Ermüdungserscheinungen und zum Bruch des Bremsbügels kommen.In the known ski brake, the base plate bearings of the brake bracket are exposed to relatively large mechanical loads. The floating bearing openings of the legs of the base plate not only have to absorb the forces that occur during the elastic deformation of the brake bracket to generate the restoring force, but are additionally loaded by the forces that occur when the brake bracket is stretched in the standby position. The relatively narrow contact surfaces of the floating bearings are slightly deformed, with the result that the free ends of the brake arm legs can no longer be pivoted into the ready position. In addition, the swivel angle by which the free ends can be swiveled in toward the center of the ski is relatively small. Since in the known ski brake the brake bar is still biased into the braking position by internal stress, fatigue and breakage of the brake bar can occur.

Aus der DE-OS 29 06 477 ist eine Skibremse bekannt, bei der zwei Bremshebel zwischen ihren beiden Enden an einer Grundplatte um eine feststehende, quer zur Skilängsrichtung und parallel zur Skioberseite verlaufende Achse schwenkbar gelagert sind. Das eine Ende jedes Bremshebels steht frei ab und bildet einen in der Bremsstellung unter den Ski reichenden Bremsarm, während das andere Ende über ein Gelenk mit einer Trittplatte verbunden ist. Die Schwenkachse dieses Gelenks verläuft hierbei parallel zur Schwenkachse des Grundplattenlagers. Das dem Gelenk abgewandte Ende der Trittplatte ist schwenkbar an Führungsorganen gelagert, die in Skilängsrichtung verschiebbar an der Grundplatte geführt sind. Gesonderte Federn spannen die Führungsorgane so vor, daß die Bremshebel über die Trittplatte in die Bremsstellung geklappt werden. Beim Niederdrücken der Trittplatte in ihre Bereitschaftsstellung werden die freien Enden der Bremshebel angehoben. Bei der bekannten Skibremse ragen die freien Enden der Bremshebel in der Bereitschaftsstellung über die Skiseitenkanten vor, was das Unfall- und Verletzungsrisiko des Skifahrers erhöht. Darüber hinaus werden die Grundplattenlager in der Bereitschaftsstellung der Skibremse durch die Vorspannfedern beaufschlagt, was ihre Lebensdauer beeinträchtigen kann.From DE-OS 29 0 6 477 a ski brake is known in which two brake levers are pivotally mounted between their two ends on a base plate about a fixed axis running transversely to the longitudinal direction of the ski and parallel to the top of the ski. One end of each brake lever protrudes freely and forms a brake arm reaching under the ski in the braking position, while the other end is connected to a tread plate via a joint. The pivot axis of this joint runs parallel to the pivot axis of the base plate bearing. The end of the tread plate facing away from the joint is pivotally mounted on guide members which are guided on the base plate so as to be displaceable in the longitudinal direction of the ski. Separate springs pre-tension the guide elements so that the brake levers move into the braking position via the tread plate be folded. The free ends of the brake levers are raised when the tread plate is pressed down into its ready position. In the known ski brake, the free ends of the brake levers protrude beyond the ski side edges in the ready position, which increases the risk of accidents and injuries to the skier. In addition, the base plate bearings are acted upon by the preload springs when the ski brake is in the ready position, which can affect their service life.

Aufgabe der Erfindung ist es, eine Skibremse mit in der Bereitschaftsstellung zur Skimitte hin einziehbaren freien Bremshebelenden so zu verbessern, daß die Bremsarme sowohl in der Bereitschaftsstellung als auch in der Bremsstellung keine Vorspannkräfte aufnehmen müssen.The object of the invention is to improve a ski brake with retractable free brake lever ends in the standby position towards the center of the ski so that the brake arms do not have to absorb any pretensioning forces either in the standby position or in the braking position.

Diese Aufgabe wird ausgehend von der eingangs näher erläuterten Skibremse dadurch gelöst, daß der Bremshebel über ein - gesehen in Skilängsrichtung - zwischen der zweiten Achse seines Grundplattenlagers und der Skimitte angeordnetes, für die Schwenkbewegung um zur ersten und zweiten Achse etwa parallele Achsen eingerichtetes Gelenk mit der Trittplatte verbunden ist, daß das dem Gelenk in Skilängsrichtung abgewandte Ende der Trittplatte an Führungsorganen in Skilängsrichtung verschiebbar und um eine zur oberen Skifläche etwa parallele, quer zum Ski verlaufende Achse schwenkbar an der Grundplatte geführt und durch wenigstens eine gesonderte Feder in die durch einen Anschlag der Grundplatte festgelegte Bremsstellung vorgespannt ist, und daß die Schubfläche an dem das Gelenk des Bremshebels tragenden Ende der Trittplatte angreift.This object is achieved on the basis of the ski brake explained in more detail above in that the brake lever is arranged via a joint, arranged in the longitudinal direction of the ski, between the second axis of its base plate bearing and the center of the ski, for the pivoting movement about axes approximately parallel to the first and second axes Tread plate is connected that the end of the tread plate facing away from the joint in the longitudinal direction of the ski can be moved on guide members in the longitudinal direction of the ski and pivoted on the base plate about an axis which is approximately parallel to the upper ski surface and runs transversely to the ski and by at least one separate spring into which by a stop Base plate fixed brake position is biased, and that the thrust surface engages the end of the tread plate carrying the joint of the brake lever.

Das Gelenk des Bremshebels mit der Trittplatte als auch das Grundplattengelenk sind sowohl in der Bremsstellung als auch in der Bereitschaftsstellung von der Vorspannkraft ler Feder entlastet. Insbesondere ist hierbei von Vorteil, laß diese Gelenke bereits beim Einschwenken der freien Enden der Bremsarme zur Skimitte hin nur unwesentlichen Kräften ausgesetzt sind, was die Lebensdauer der Gelenke beträchtlich erhöht. Bei der Annäherung an die Bereitschaftsstellung werden die Vorspannkräfte über die Trittplatte und die schräge Schubfläche unmittelbar, d.h. nicht auf dem Umweg über die Bremshebel,in die Grundplatte eingeleitet. In der Bremsstellung sitzt das den Bremshebeln abgewandte Ende der Trittplatte bzw. sitzen die Führungsorgane, an denen sie gelagert ist, an dem Anschlag der Grundplatte an.The joint of the brake lever with the tread plate and the base plate joint are both in the braking position Relieved of the spring preload force even in the standby position. It is particularly advantageous here that these joints are exposed to only insignificant forces when the free ends of the brake arms are pivoted in towards the center of the ski, which considerably increases the lifespan of the joints. When approaching the standby position, the pretensioning forces are introduced into the base plate via the tread plate and the inclined thrust surface, ie not via the brake lever. In the braking position, the end of the tread plate facing away from the brake levers is seated, or the guide elements on which it is mounted bear against the stop of the base plate.

Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß an der Grundplatte ein um die zweite Achse schwenkbares Lagerteil mit einer in Richtung der ersten Achse verlaufenden Lageröffnung befestigt ist, daß vom einen Ende einer die Lageröffnung schwenkbar durchsetzenden Gelenkwelle des Bremshebels ein Bremsarm frei absteht und vom gegenüberliegenden anderen Ende ein Kurbelarm dem Bremsarm entgegengesetzt absteht, und daß der Kurbelarm im Abstand von der Gelenkwelle einen Gelenkzapfen trägt, der in eine Los-, lageröffnung der Trittplatte eingreift. Das Loslager des-Kurbelarms an der Trittplatte hat den Vorteil, daß es einfach herstellbar ist. Das die Gelenkwelle des Bremshebels aufnehmende Lagerteil verbessert die Haltbarkeit des Grundplattenlagers bei Schwenkbewegungen um die erste Achse. Die um die zweite Achse schwenkbare Befestigung des Lagerteils an der Grundplatte ist unkritisch, da das Lagerteil um diese Achse lediglich im entlasteten Zustand geschwenkt wird.A preferred embodiment is characterized in that a pivotable about the second axis bearing part is fixed to the base plate with a bearing opening running in the direction of the first axis, that from one end of a pivoting shaft through the bearing opening of the brake lever, a brake arm protrudes freely and the other from the opposite End a crank arm protrudes opposite the brake arm, and that the crank arm carries a hinge pin at a distance from the drive shaft, which engages in a loose, bearing opening of the tread plate. The floating bearing of the crank arm on the tread plate has the advantage that it is easy to manufacture. The bearing part receiving the propeller shaft of the brake lever improves the durability of the base plate bearing during pivoting movements about the first axis. The pivotable attachment of the bearing part to the base plate about the second axis is not critical since the bearing part is pivoted about this axis only in the unloaded state.

Als besonders günstig haben sich Ausführungsformen erwiesen, bei welchen das Lagerteil als zylindrischer Zapfen ausgebildet ist, der drehbar, aber axial fest in einer mit der zweiten Achse achsparallelen zylindrischen Aussparung der Grundplatte sitzt und eine zur Zylinderachse normale Lageröffnung für die Gelenkwelle des Bremshebels aufweist. Solche Zapfen sind einfach und kostengünstig herstellbar. Da sie mit der gesamten Umfangsfläche in der Aussparung der Grundplatte führen, ergibt sich ein stabiles Grundplattenlager.Embodiments in which the bearing part is designed as a cylindrical pin have proven particularly favorable is rotatable but axially fixed in a cylindrical recess of the base plate which is axially parallel to the second axis and has a bearing opening for the drive shaft of the brake lever which is normal to the cylinder axis. Such pins are simple and inexpensive to manufacture. Since they run with the entire circumferential surface in the recess of the base plate, a stable base plate bearing results.

Bei dem Bremshebel handelt es sich um ein steifes, bevorzugt als Biegeformteil ausgebildetes Bauteil. Aufgrund der Bewegungsgeometrie des in der Trittplatte geführten Gelenkzapfens relativ zu der im Lagerteil geführten Gelenkwelle bewegt sich die Gelenkwelle bei der Annäherung an die Bereitschaftsstellung in Richtung ihrer ersten Schwenkachse relativ zum Gelenkzapfen des Kurbelarms. Um diese Ausgleichsbewegung beim Einschwenken der freien Enden der Bremsarme zur Skimitte hin ausführen zu können, ist die Gelenkwelle vorzugsweise axial verschiebbar in der Lageröffnung des Zapfens geführt. Die Achse der Lageröffnung schneidet hierbei zweckmäßigerweise die Zylinderachse des Zapfens.The brake lever is a rigid component which is preferably designed as a bent molded part. Due to the movement geometry of the articulated pin guided in the footplate relative to the articulated shaft guided in the bearing part, the articulated shaft moves relative to the articulated pin of the crank arm as it approaches the ready position in the direction of its first pivot axis. In order to be able to carry out this compensating movement when the free ends of the brake arms are pivoted toward the center of the ski, the cardan shaft is preferably guided axially displaceably in the bearing opening of the pin. The axis of the bearing opening advantageously intersects the cylinder axis of the pin.

Die zweite, lotrechte Schwenkachse des Lagerteils kann aber auch - gesehen quer zur Skilängsrichtung - im Abstand zur Spur der ersten Achse, d.h. im Abstand zur Achse der Gelenkwelle, vorgesehen sein. Hierzu kann die Achse der Lageröffnung des Zapfens windschief zur Zylinderachse verlaufen. Alternativ kann das Lagerteil als Schwenkarm ausgebildet sein, dessen eines Ende um die zweite Achse schwenkbar an der Grundplatte befestigt ist und dessen anderes Ende eine Lageröffnung für die Gelenkwelle des Bremshebels aufweist.The second, vertical pivot axis of the bearing part can also - seen transversely to the longitudinal direction of the ski - at a distance from the track of the first axis, i.e. at a distance from the axis of the propeller shaft. For this purpose, the axis of the bearing opening of the journal can be skewed to the cylinder axis. Alternatively, the bearing part can be designed as a swivel arm, one end of which is fastened to the base plate so as to be pivotable about the second axis and the other end of which has a bearing opening for the drive shaft of the brake lever.

Als günstig hat es sich erwiesen, wenn die Grundplatte - gesehen in Skilängsrichtung - zwischen dem Kurbelarm und dem Bremsarm zumindest im Bereich des Gelenkzapfens des Kurbelarms eine zum Kurbelarm weisende Anschlagfläche aufweist, an der der Kurbelarm bei der Annäherung an die Bereitschaftsstellung anliegt. In dieser Ausführungsform läßt sich das freie Ende des Bremshebels besonders weit zur Skimitte hin einschwenken. Bei Annäherung an die Bereitschaftsstellung wird der Gelenkzapfen des Kurbelarms zunächst nach außen gedrückt, wodurch das freie Ende um die zweite Achse des Grundplattenlagers herum zur Skimitte hin einschwenkt. Sobald der Kurbelarm jedoch an der Anschlagfläche anliegt, kippt im wesentlichen der gesamte Bremshebel um den Anlagepunkt an der Anschlagfläche unter gleichzeitiger Axialverschiebung der in der Grundplatte gelagerten Gelenkwelle des Bremshebels.It has proven to be advantageous if the base plate - seen in the longitudinal direction of the ski - between the crank arm and the brake arm, at least in the region of the pivot pin of the crank arm, has a stop surface facing the crank arm, against which the crank arm rests when the ready position is approached. In this embodiment, the free end of the brake lever can be pivoted particularly far towards the center of the ski. When approaching the standby position, the pivot pin of the crank arm is first pressed outwards, whereby the free end swings around the second axis of the base plate bearing towards the center of the ski. However, as soon as the crank arm rests on the stop surface, essentially the entire brake lever tilts around the contact point on the stop surface with simultaneous axial displacement of the drive shaft of the brake lever mounted in the base plate.

Um ein Verkanten der Trittplatte zu vermeiden, sind bevorzugt zwei zur Skimitte symmetrische Bremshebel vorgesehen, wobei die Grundplatte zwischen den Kurbelarmen der Bremshebel einen Schubklotz trägt. Der Schubklotz hat zweckmäßigerweise zwei konvex gewölbte Schubflächen, die symmetrisch zur Skimitte mit Querabstand voneinander angeordnet sind.In order to prevent the tread plate from tilting, two brake levers symmetrical to the center of the ski are preferably provided, the base plate carrying a thrust block between the crank arms of the brake levers. The thrust block expediently has two convexly curved thrust surfaces which are arranged symmetrically to the center of the ski at a transverse distance from one another.

In einer bevorzugten Ausführungsform ist vorgesehen, daß. die Grundplatte ein im wesentlichen U-förmiges Kunststoff-Formteil aufweist, dessen in Skilängsrichtung verlaufende Schenkel die Trittplatte in der Bereitschaftsstellung zwischen sich aufnehmen, daß der bzw. die Bremshebel und die Führungsorgane der Trittplatte an den Schenkeln gelagert sind, und daß die schräge Schubfläche mit Abstand von beiden Schenkeln am Querteil des Formteils vorgesehen ist. In dieser Ausführungsform liegt die Trittplatte in der Bereitschaftsstellung geschützt zwischen den Schenkeln.In a preferred embodiment it is provided that. the base plate has a substantially U-shaped plastic molded part, the legs of which extend in the longitudinal direction of the ski receive the tread plate between them in the ready position, that the brake lever or brakes and the guide members of the tread plate are mounted on the legs, and that the inclined thrust surface includes Distance from both legs is provided on the cross part of the molded part. In this embodiment, the tread plate is protected between the legs in the ready position.

Fertigungstechnische Vorteile bietet eine Verbesserung dieser Ausführungsform, bei der der Bremshebel um die erste Achse schwenkbar an einem Lagerteil gelagert ist, welches seinerseits um die zweite Achse schwenkbar in einer zum Ski hin offenen Ausnehmung des Schenkels des Formteils sitzt, wenn das Formteil an einer insbesondere aus Metall gefertigten Halteplatte befestigt ist, die die Ausnehmung zum Ski hin verschließt. Die Halteplatte steift das Formteil aus und sorgt für die nötige Verwindungssteifheit der Grundplatte. Durch die zweiteilige Ausführung der Grundplatte wird der Zusammenbau der Skibremse erleichtert.Manufacturing technology offers an improvement of this embodiment, in which the brake lever is pivotally mounted about the first axis on a bearing part, which in turn is pivotable about the second axis in a recess open to the ski of the leg of the molded part, if the molded part in particular from Metal-made mounting plate is attached, which closes the recess to the ski. The holding plate stiffens the molded part and ensures the necessary torsional rigidity of the base plate. The two-part design of the base plate makes it easier to assemble the ski brake.

Bevorzugt ist jedes Führungsorgan der Trittplatte als Winkelstück ausgebildet, dessen erster in Skilängsrichtung verlaufender Schenkel in einer Ausnehmung des Schenkels des Formteils in Skilängsrichtung verschiebbar geführt ist und dessen zweiter Schenkel einen in eine Lageröffnung der Trittplatte eingreifenden Lagerzapfen bildet. Die Halteplatte weist hierbei vor die freien Enden der Schenkel des Formteils greifende, vom ersten Schenkel des Winkelstücks jeweils verschiebbar durchsetzte Führungsflansche auf. Das freie Ende des ersten Schenkels des Winkelstücks trägt ein Widerlager für eine den ersten Schenkel umschließende Schraubendruckfeder, die zwischen dem Widerlager und dem-Führungsflansch eingespannt ist. Der Führungsflansch bildet zugleich den die Bremsstellung festlegenden Anschlag und leitet Belastungskräfte der Trittplatte unmittelbar in die am Ski befestigte Halteplatte ein. Das aus Kunststoff bestehende Formteil ist somit keinen wesentlichen Lagerkräften ausgesetzt.Each guide member of the tread plate is preferably designed as an angle piece, the first leg of which extends in the longitudinal direction of the ski is displaceably guided in a recess of the leg of the molded part in the longitudinal direction of the ski and the second leg of which forms a bearing pin engaging in a bearing opening of the tread plate. The holding plate has in front of the free ends of the legs of the molded part, through which the first leg of the angle piece is displaceably penetrated guide flanges. The free end of the first leg of the elbow carries an abutment for a helical compression spring surrounding the first leg, which is clamped between the abutment and the guide flange. The guide flange also forms the stop defining the braking position and transmits load forces of the tread plate directly into the holding plate attached to the ski. The molded part made of plastic is therefore not exposed to any significant bearing forces.

In der letztgenannten Ausführungsform sitzt der erste Schenkel des Winkelstücks bevorzugt in einer zur Halteplatte geschlossenen Ausnehmung des Schenkels des Formteils. Die , Halteplatte ist zumindest im Bereich des Grundplattenlagers des Bremshebels durch Befestigungsmittel, insbesondere Nieten, mit dem Formteil verbunden. Die Zahl der anzubringenden Nieten ist in dieser Ausführungsform sehr gering, da das Formteil im übrigen mittels des Winkelstücks an der Halteplatte gehalten wird. Da der erste Schenkel einschließlich der Schraubendruckfeder auf diese Weise in einer geschlossenen Kammer sitzt, werden auch Betriebsstörungen durch Verschmutzen vermieden.In the last-mentioned embodiment, the first leg of the angle piece preferably sits in a recess of the leg of the molded part which is closed to the holding plate. The , Holding plate is connected to the molded part at least in the area of the base plate bearing of the brake lever by fastening means, in particular rivets. The number of rivets to be attached is very small in this embodiment, since the molded part is otherwise held on the holding plate by means of the angle piece. Since the first leg, including the helical compression spring, is seated in a closed chamber in this way, malfunctions due to contamination are also avoided.

In einer bevorzugten Ausführungsform weist der Bremshebel ferner zwischen dem Grundplattenlager und seinem freien Ende Z-förmige Abkröpfung auf, die in der Bremsstellung etwa parallel zur Skilängsrichtung verläuft und in der Bereitschaftsstellung zum freien Ende hin nach oben ansteigt. In dieser Ausführungsform kann das freie Ende des Bremshebels besonders weit über die obere Skifläche hinaus angehoben werden.In a preferred embodiment, the brake lever also has a Z-shaped bend between the base plate bearing and its free end, which runs approximately parallel to the longitudinal direction of the ski in the braking position and rises upwards towards the free end in the ready position. In this embodiment, the free end of the brake lever can be raised particularly far beyond the upper ski surface.

Im folgenden soll ein Ausführungsbeispiel der Erfindung anhand von Zeichnungen näher erläutert werden. Es zeigt:

In the following, an embodiment of the invention will be explained in more detail with reference to drawings. It shows:
  • Fig. 1 is a partially broken plan view of a first embodiment of a ski. brake, in which the upper part of the figure is drawn in the braking position, the lower part in the standby position of the ski brake;

Die in den Fig. 1 bis 3 dargestellte Skibremse umfaßt eine durch nicht näher dargestellte Befestigungsorgane an einem Ski 1 befestigte Grundplatte 3, bestehend aus einem U-förmigem Kunststoff-Formteil 5 mit zwei in Skilängsrichtung sich erstreckenden Schenkeln 7 und 9, die über einen flacheren Steg 11 einstückig miteinander verbunden sind. Das Formteil 5 ist auf einer im wesentlichen umrißgleichen, metallischen Halteplatte 13 befestigt, die das Formteil 5 aussteift.The ski brake shown in FIGS. 1 to 3 comprises a base plate 3 fastened to a ski 1 by fastening elements, not shown, consisting of a U-shaped plastic molded part 5 with two legs 7 and 9 extending in the longitudinal direction of the ski, which have a flatter surface Web 11 are integrally connected. The molded part 5 is fastened on a substantially identical, metallic holding plate 13 which stiffens the molded part 5.

In jedem der Schenkel 7 bzw. 9 ist ein als Biegeformteil ausgebildeter Bremshebel 15 bzw. 17 um zwei zueinander senkrecht stehende Achsen 19 (Fig. 1) bzw. 21 (Fig. 3) schwenkbar gelagert. Die Bremshebel 15 und 17 sind symmetrisch zur Skimitte ausgebildet, so daß im folgenden lediglich der Bremshebel 15 beschrieben werden soll. Die Achse 19 verläuft etwa parallel zur Oberseite des Skis 1 und in der Bremsstellung etwa lotrecht zur Skilängsrichtung. Sie wird durch eine Gelenkwelle 23 des Bremshebels 15 festgelegt, die eine zur Halteplatte 13 hin offene und von dieser verschlossene Lageröffnung 25 eines zylindrischen Zapfens 27 durchsetzt. Der Zapfen 27 sitzt drehbar in einer zur Halteplatte 13 hin offenen und von dieser verschlossenen zylindrischen Ausnehmung 29 des Schenkels 7 bzw. 9 des Formteils 5. Seine die Drehachse 21 bildende Zylinderachse verläuft senkrecht zur Oberfläche des Skis und schneidet die Achse 19.In each of the legs 7 and 9, a brake lever 15 and 17 designed as a bent molded part is pivotably mounted about two mutually perpendicular axes 19 (FIG. 1) and 21 (FIG. 3). The brake levers 15 and 17 are symmetrical to the center of the ski, so that only the brake lever 15 will be described below. The axis 19 runs approximately parallel to the top of the ski 1 and in the braking position approximately perpendicular to the longitudinal direction of the ski. It is fixed by an articulated shaft 23 of the brake lever 15 which passes through a bearing opening 25 of a cylindrical pin 27 which is open towards the holding plate 13 and is closed by the latter. The pin 27 is rotatably seated in a cylindrical recess 29 of the leg 7 or 9 of the molded part 5 which is open towards the holding plate 13 and is closed by it. Its cylinder axis forming the axis of rotation 21 runs perpendicular to the surface of the ski and intersects the axis 19.

Die Gelenkwelle 23 setzt sich auf der außen gelegenen Seite der Grundplatte 3 etwa rechtwinklig gebogen in Form eines frei abstehenden Bremsarms 31 fort. Am freien Ende des Bremsarms 31 ist eine Kunststoffkralle 33 angeformt. Die Gelenkwelle 23 setzt sich auf der innen gelegenen Seite des Schenkels 7 bzw. 9 in Form eines Kurbelarms 35 fort, der etwa rechtwinklig zur Gelenkwelle 23 abgebogen ist und entgegengesetzt zum Bremsarm 31 absteht. Der Kurbelarm 35 trägt an seinem der Gelenkwelle 23 abgewandten Ende einen zur Skimitte hin etwa parallel zur Gelenkwelle 23 abstehenden Gelenkzapfen 37, der in eine Loslageröffnung 39 einer Trittplatte 41 eingreift. Die Loslageröffnung 39 wird durch den mit Abstand zum Schenkel 7 verlaufenden Querrand einer Umbördelung 43 der Trittplatte 41 gebildet. Die Umbördelung 43 erweitert sich zur Skimitte hin, so daß der Gelenkzapfen 37 der Schwenkbewegung des Bremshebels 15 bzw. 17 um die lotrechte Achse 21 folgen kann.The propeller shaft 23 continues on the outer side of the base plate 3 bent approximately at right angles in the form of a freely projecting brake arm 31. A plastic claw 33 is formed on the free end of the brake arm 31. The propeller shaft 23 continues on the inside of the leg 7 or 9 in the form of a crank arm 35 which is bent approximately at right angles to the propeller shaft 23 and protrudes opposite the brake arm 31. The crank arm 35 carries at its end facing away from the drive shaft 23 an articulated pin 37 which projects approximately parallel to the drive shaft 23 and which engages in a floating bearing opening 39 of a step plate 41. The floating bearing opening 39 is formed by the transverse edge of a flange 43 of the tread plate 41 which runs at a distance from the leg 7. The flange 43 widens towards the center of the ski, so that the pivot pin 37 can follow the pivoting movement of the brake lever 15 or 17 about the vertical axis 21.

Das der Umbördelung 43 in Skilängsrichtung gegenüberliegende Ende der Trittplatte 41 ist über Winkelstücke 45 in Skilängsrichtung verschiebbar an den Schenkeln 7 bzw. 9 geführt. Die Winkelstücke 45 umfassen jeweils einen vom Schenkel 7 bzw. 9 der Grundplatte 3 zur Skimitte weisenden Gelenkschenkel 47, der in eine der Umbördelung 43 in Skilängsrichtung gegenüberliegende, an der Trittplatte 41 angebördelte Gelenklasche 49 der Trittplatte 41 eingreift. Mit seinem anderen Schenkel 51 ist das Winkelstück 45, wie am besten aus Fig. 3 ersichtlich, in einer in Skilängsrichtung verlaufenden zylindrischen, zur Halteplatte 13 hin geschlossenen Aussparung 53 verschiebbar geführt. Die Halteplatte 13 trägt, gesehen in Skilängsrichtung, außerhalb der Schenkel 7, 9 hochstehende Flansche 55, die die Schenkel 7, 9 zwischen sich einschließen. Von den Flanschen 55 sind Führungsflansche 57 vor die freien Stirnenden der Schenkel 7 bzw. 9 gebogen. Die Schenkel 51 der Winkelstücke 45 durchsetzen Führungsöffnungen 59 der die Ausnehmungen 53 verschließenden Führungsflansche 57. Jeden Schenkel 51 umschließt eine Schraubendruckfeder 61, die zwischen dem Führungsflansch 57 und einem am freien Ende des Schenkels 51 angebrachten Widerlager 63 eingespannt ist. Die Führungsöffnung 59 ist in größerem Abstand von der Skioberfläche angeordnet als die Lageröffnung 25 der Gelenkwelle 23 des Bremshebels 15 bzw. 17. Zum Ausgleich sind die Kurbelarme 35 zwischen den Gelenkzapfen 37 und den Gelenkwellen 23 von der Halteplatte 13 weggebogen.The end of the tread plate 41 opposite the flanging 43 in the longitudinal direction of the ski is guided on the legs 7 and 9 so as to be displaceable in the longitudinal direction of the ski via angle pieces 45. The angle pieces 45 each comprise an articulated leg 47, which points from the leg 7 or 9 of the base plate 3 to the center of the ski and which engages in an articulated flap 49 of the tread plate 41, which is opposite the flange 43 in the longitudinal direction of the ski and is flanged on the tread plate 41. With its other leg 51, the angle piece 45, as can best be seen from FIG. 3, is displaceably guided in a cylindrical recess 53 which runs in the longitudinal direction of the ski and is closed towards the holding plate 13. The holding plate 13, seen in the longitudinal direction of the ski, carries upstanding flanges 55 outside the legs 7, 9, which enclose the legs 7, 9 between them. Of the flanges 55 are guide flanges 57 in front of the free ends Legs 7 and 9 bent. The legs 51 of the angle pieces 45 pass through guide openings 59 of the guide flanges 57 closing the recesses 53. Each leg 51 is surrounded by a helical compression spring 61 which is clamped between the guide flange 57 and an abutment 63 attached to the free end of the leg 51. The guide opening 59 is arranged at a greater distance from the ski surface than the bearing opening 25 of the propeller shaft 23 of the brake lever 15 or 17. To compensate, the crank arms 35 between the pivot pin 37 and the propeller shafts 23 are bent away from the holding plate 13.

An einer zur Trittplattehinweisenden Verlängerung 65 des Stegs 11 des Formteils 5 ist ein Schubklotz 67 angebracht, der symmetrisch zur Skimitte in Abstand von den Schenkeln 7, 9 und mit Abstand voneinander zwei konvex, zur Trittplatte 41 hin gekrümmte, schräge Schubflächen 69 aufweist. Die Schubflächen 69 wirken mit dem zugewandten, teilzylindrischen Außenrand der Umbördelung 43 zusammen und verschieben die am Schubklotz 67 abstützbare Trittplatte 41 in Skilängsrichtung.On an extension 65 of the web 11 of the molded part 5 pointing towards the tread plate, a push block 67 is attached, which symmetrically to the center of the ski at a distance from the legs 7, 9 and at a distance from one another has two convex, oblique thrust surfaces 69 curved towards the tread plate 41. The thrust surfaces 69 cooperate with the facing, partially cylindrical outer edge of the flange 43 and shift the tread plate 41 which can be supported on the thrust block 67 in the longitudinal direction of the ski.

Die Skibremse arbeitet wie folgt:

  • In der Bremsstellung wird die Trittplatte 41 in die in Fig. 1 oben bzw. den Fig. 2 und 3 dargestellte Stellung vorgespannt. Das mit den Kurbelarmen 35 verbundene hintere Ende der Trittplatte 41 ist von der Grundplatte 3 entfernt, und die Bremsarme 31 ragen unter die Skilauffläche. Die Gelenkschenkel 47 liegen an den Führungsflanschen 57 der Halteplatte 13 an, leiten also die Federvorspannung der Schraubendruckfedern 61 unmittelbar in die Halteplatte 13 ein. Die Gelenkzapfen 37 und die Gelenkwellen 23 sind von den Vorspannkräften entlastet.
The ski brake works as follows:
  • In the braking position, the tread plate 41 is biased into the position shown in FIG. 1 above or in FIGS. 2 and 3. The rear end of the tread plate 41 connected to the crank arms 35 is removed from the base plate 3, and the brake arms 31 protrude under the ski tread. The articulated limbs 47 rest on the guide flanges 57 of the holding plate 13, thus direct the spring preload of the helical compression springs 61 directly into the holding plate 13. The pivot pin 37 and the propeller shafts 23 are relieved of the prestressing forces.

Beim Schließen der Skibindung drückt die Sohle des Skistiefels die Trittplatte 41 zur Grundplatte 3. Die über die Winkelstücke 45 verschiebbar an der Grundplatte 3 geführte Trittplatte 41 verschiebt sich hierbei längs der Grundplatte 3, wie dies in Fig. 1 unten und in Fig. 2 (gestrichelt) dargestellt ist. Die über die Gelenkzapfen 37 mit der Trittplatte 41 verbundenen Bremshebel 15, 17 schwenken zunächst ausschließlich um die Achse 19 der Gelenkwellen 23, wobei die Bremsarme 31 vollständig über die obere Skifläche hinaus angehoben werden.When the ski binding is closed, the sole of the ski boot presses the tread plate 41 toward the base plate 3. The tread plate 41, which is displaceable on the base plate 3 via the angle pieces 45, moves here along the base plate 3, as shown in FIG. 1 below and in FIG. dashed) is shown. The brake levers 15, 17 connected to the tread plate 41 via the hinge pins 37 initially pivot exclusively about the axis 19 of the drive shafts 23, the brake arms 31 being raised completely beyond the upper ski surface.

Bei Annäherung an die Bereitschaftsstellung, in der die Skibindung geschlossen ist, setzt die Umbördelung 43 der Trittplatte 41 auf die Schubfläche 69 des Schubklotzes 67 auf. Der Schubklotz 67 verschiebt die Trittplatte 41 zusätzlich zur Kurbelgeometrie der Kurbelarme 35 in Skilängsrichtung. Die in den Zapfen 27 sitzenden Gelenkwellen 23 werden hierdurch um die Achse 21 (Fig. 3) der Zapfen 27 geschwenkt, wobei das hierfür erforderliche Drehmoment sich aus dem - gesehen in Skilängsrichtung - vorhandenen Abstand der Loslager 39 von der Achse 21 ergibt. Im Verlauf der Schwenkbewegung um die Achse 21 schlägt das dem Schenkel 7 bzw. 9 des Formteils 5 zugewandte freie Ende 71 des Kurbelarms 35 an Flächen 72 der Schenkel 7 bzw. 9 an. Bei der weiteren Schubbewegung der Trittplatte 41 kippt der Kurbelarm 35 um diesen Anlagepunkt, womit im wesentlichen der gesamte Bremshebel 15 bzw. 17 über einen relativ kleinen Hebelarm zur Skimitte hin eingeschwenkt wird. Die Gelenkwellen 23 der Hebelarme 15, 17 verschieben sich hierbei axial in den Lageröffnungen 25 der Zapfen 27. Während der Schwenkbewegung beim Einziehen der Bremsarme 31 stützt sich die Trittplatte 41 über den Schubklotz 67 an der Grundplatte 3 ab, womit die Lagerzapfen 37 und die Gelenkwellen 23 frei von der Vorspannung der Druckfedern 61 sind. In beiden Endstellungen der Trittplatte 41 sind somit diese Gelenke unbelastet, was sich vorteilhaft auf die Lebensdauer auswirkt.When approaching the standby position, in which the ski binding is closed, the flange 43 of the tread plate 41 is placed on the push surface 69 of the push block 67. The push block 67 moves the tread plate 41 in addition to the crank geometry of the crank arms 35 in the longitudinal direction of the ski. The propeller shafts 23 seated in the journal 27 are thereby pivoted about the axis 21 (FIG. 3) of the journal 27, the torque required for this resulting from the distance of the floating bearings 39 from the axis 21, as seen in the longitudinal direction of the ski. In the course of the pivoting movement about the axis 21, the free end 71 of the crank arm 35 facing the leg 7 or 9 of the molded part 5 strikes surfaces 72 of the leg 7 or 9. With the further pushing movement of the tread plate 41, the crank arm 35 tilts about this contact point, whereby essentially the entire brake lever 15 or 17 is pivoted in via a relatively small lever arm towards the center of the ski. The articulated shafts 23 of the lever arms 15, 17 shift axially in the bearing openings 25 of the pins 27. During the swiveling movement when the brake arms 31 are pulled in, the tread plate 41 is supported on the base plate 3 via the thrust block 67, with the result that the journals 37 and the articulated shafts 23 are free from the bias of the compression springs 61. In both end positions Footplate 41, these joints are thus unloaded, which has an advantageous effect on the service life.

Die Bremsarme 31 weisen zwischen ihrem freien Ende und der Gelenkwelle 23 eine Abkröpfung 73 auf, die in der Bremsstellung zwischen der oberen und der unteren Fläche des Skis 1 parallel zu diesen Flächen verläuft und in der Bereitschaftsstellung von der Grundplatte 3 weg nach oben führt. Auf diese Weise wird der Abstand der Krallen 33 von der oberen Skifläche in der Bereitschaftsstellung vergrößert.The brake arms 31 have an offset 73 between their free end and the propeller shaft 23, which runs parallel to these surfaces in the braking position between the upper and the lower surface of the ski 1 and leads away from the base plate 3 in the ready position. In this way, the distance of the claws 33 from the upper ski surface is increased in the ready position.

Das Formteil 5 wird durch Nieten 75, die die Schenkel 7 bzw. 9 im Bereich des Stegs 11 durchdringen, an der Halteplatte 13 befestigt. Die freien Enden der Schenkel 7, 9 werden von den Flanschen 55 einerseits und dem durch die Führungsflansche 57 tretenden Schenkel 51 der Winkelstükke 45 an der Halteplatte 13 fixiert.The molded part 5 is fastened to the holding plate 13 by rivets 75 which penetrate the legs 7 and 9 in the region of the web 11. The free ends of the legs 7, 9 are fixed on the holding plate 13 by the flanges 55 on the one hand and the leg 51 of the angle pieces 45 passing through the guide flanges 57.

Fig. 4 zeigt eine andere Ausführungsform einer Skibremse, die sich von der vorstehend erläuterten Skibremse im wesentlichen nur durch die Art der Lagerung ihrer Bremshebel 101, von denen lediglich ein einziger dargestellt ist, an einer am Ski zu befestigenden Grundplatte 103 unterscheidet. Der Bremshebel 101 ist in Fig. 4 mit ausgezogenen Linien für die Bremsstellung und mit gestrichelten Linien für die Bereitschaftsstellung dargestellt. Seine Gelenkwelle 105 ist um eine in der Bremsstellung parallel zur oberen Skifläche und lotrecht zur Skilängsrichtung verlaufende Achse in einer Lageröffnung an einem Ende eines Arms 107 schwenkbar gelagert. Der Arm 107 ist an seinem anderen Ende an einem zylindrischen Zapfen 109 um eine zur oberen Skifläche senkrechte Achse schwenkbar an der Grundplatte 103 gelagert. Der Zapfen 109 kann fest mit dem Arm 107 verbunden und gegenüber der Grundplatte 103 drehbar sein oder aber fest an der Grundplatte 103 befestigt sein und als Lagerzapfen für den relativ dazu drehbaren Arm 107 dienen. Die Wirkungsweise und der sonstige Aufbau der Skibremse entspricht der Skibremse der Fig. 1 bis 3 mit dem Unterschied, daß die Schwenkwelle 105 des Bremshebels 101 keine Axialbewegung relativ zur Lageröffnung des durch den Arm 107 und den Zapfen 109 gebildeten Grundplattenlagers ausführt. Die Gelenkwelle 105 kann vielmehr axial fest in der Lageröffnung des Arms 107 sitzen. Der Arm 107 ermöglicht trotzdem das Einschwenken des Bremshebels 101.FIG. 4 shows another embodiment of a ski brake, which differs from the ski brake explained above essentially only in the manner in which its brake levers 101 are mounted, only one of which is shown, on a base plate 103 to be attached to the ski. The brake lever 101 is shown in FIG. 4 with solid lines for the braking position and with dashed lines for the standby position. Its articulated shaft 105 is pivotally mounted in a bearing opening at one end of an arm 107 about an axis running parallel to the upper ski surface in the braking position and perpendicular to the longitudinal direction of the ski. The arm 107 is mounted on the base plate 103 at its other end on a cylindrical pin 109 such that it can pivot about an axis perpendicular to the upper ski surface. The pin 109 can be firmly connected to the arm 107 and be rotatable relative to the base plate 103 or else be fixedly attached to the base plate 103 and serve as a bearing journal for the arm 107 which can be rotated relative thereto. The operation and the other structure of the ski brake corresponds to the ski brake of FIGS. 1 to 3 with the difference that the pivot shaft 105 of the brake lever 101 does not perform any axial movement relative to the bearing opening of the base plate bearing formed by the arm 107 and the pin 109. The propeller shaft 105 can instead be axially fixed in the bearing opening of the arm 107. The arm 107 nevertheless enables the brake lever 101 to be pivoted in.
