摘要:
The invention relates to a ski brake (1) for braking a ski (2) detached from a sports shoe, with a bearing device (3) for a brake lever arrangement (4) for placing on the upper side (5) of a ski (2). The brake lever arrangement (4) comprises brake levers (8, 9) arranged essentially symmetrically relative to the longitudinal middle axis (7) of the ski (2), which each have actuating arms (10, 11) and brake arms (12, 13). The brake arms (12, 13) project relative to the bearing device (3) and are pivotable over at least one pivot axis (15, 16) from a position of readiness located above the running surface (17) of the ski (2) by the force of a spring device (18) into a brake position projecting under the running surface (17). The actuating arms (10, 11) extend from the bearing device (3) in a direction facing away from the brake arms (12, 13) and are connected by a pivot bearing arrangement (21) with a foot plate (22) that can be loaded by the sole of a sports shoe. In this way an adjusting device (26) is formed whose adjusting force (28) forces the foot plate (22) continually into a pivot position (27) angled as far as possible relative to the actuating arms (10, 11).
摘要:
In a ski brake with brake arms (12) and actuating arms (14) a pedal (16) is mounted to the actuating arms (14) about a second transverse axis (15). A linkage arrangement (17) is provided approximately parallel to the actuating arms (14) and is pivotally connected to the pedal (16) about a third transverse axis (18) and to the ski about a fourth transverse axis (19). The fact that the spacing of the second transverse axis (15) from the third transverse axis (18) is somewhat smaller than the spacing between the first transverse axis (13) and the fourth transverse axis (19) means that the pedal (16) can execute a small counter-pivotal movement on transfer of the ski brake from the braking position into the rest position.
摘要:
A ski brake has a pair of ski elements flanking the ski and each formed by a pair of wires which in the braking position with the ski element projecting down below the bottom of the ski extend at an angle to each other, and which in the rest position extend parallel to the normal displacement direction of the ski and to each other. One of the legs of each of these elements is pivoted about an axis fixed on the ski and the other is pivoted about an axis which can be moved toward and away from the immovable axis on the ski for swinging of the elements up and down between the brake and rest positions. A spring is provided either in the form of a springy joint between the lower ends of the two legs or as a separate compression spring to urge the legs into the brake position. An actuator is displaceable from a raised or advanced position into a depressed position to move the brake elements into the rest position and is similarly urged into the raised or advanced position by the spring.

摘要:
A ski brake has a main spring element mounted upon the upper surface of a ski and resiliently biased into an operative position when the ski is released from the ski boot to bring into play at least one brake element, e.g. a blade. In order to protect the brake against impact with stones or the like, an additional spring element is provided between the actuator, which includes a pivotal member received in a mounting plate on the upper surface of the ski, and the blade or brake element so that the latter can yield on impact while retaining its braking function to prevent free flight of the ski.
摘要:
A ski braking device adapted to be preset automatically by fitting the ski boot to the ski. It comprises essentially a pair of braking arms having a common transverse shaft. These arms are normally parallel to the top surface of the ski and their shaft is rigid with a crank arm pivoted to a longitudinally movable member associated with spring means and adapted to transform the movement of rotation of said shaft into a movement of translation of said longitudinally movable member against the resistance of a spring. This arrangement constitutes a knee action mechanism and the device can operate efficiently whether the ski is sliding downhill with the ski tip or the heel end first. Means for locking the device against operation for transport or other purposes are provided.

The invention relates to a coupling device (1) between a sports shoe (2) and sports device (3), with a toe piece (5) and a heel piece (6) and a brake device (7) mounted between the latter for the sports device (3), with a longitudinal guide (9, 10) mounted on the surface (8) of the sports device (3) for the heel piece (6), in which the heel piece (6) is guided laterally and vertically in dimensions perpendicular to the longitudinal direction. The brake device (7) is provided with guiding elements (14, 15) that can engage in the guiding track (12, 13) of the longitudinal guide (9, 10) and between the brake device (7) and the heel piece (6), a longitudinal coupling device (19) is arranged for mobile connection with the heel piece (6) and the brake device (7) is guided in a play-free manner exclusively by the guiding track (12, 13) in all dimensions running perpendicular to the longitudinal direction of the guiding track (12, 13).
摘要:
A device adapted to modify the pressure distribution of a ski, such as especially an alpine ski, over its sliding surface. The device includes a sensor element adapted to sense the vertical biases of the boot, and also a linking device in order to transmit, at least towards one of the ends of the ski, in the form of a flexional moment, at least a portion of the vertical, downward thrust of the boot sensed by the sensor element. The linking device includes a calibration device to induce a pre-stress. The linking device also has a sensor which is sensitive to the presence or absence of the boot so as to automatically control the calibration device in accordance with the presence or absence of the boot. A ski brake is also provided. The brake arms are borne by one of the levers constituting the linking device and the calibration device.
摘要:
This touring binding has a sole plate, which can be pivoted about a pivot pin, fixed to the ski, and on which there are arranged a heel holder, a toe holding unit and a ski brake with two multiply angled-off brake spikes. In this arrangement there are provided in the sole plate, between the pivot pin and the heel holder, two bearings for the transversely running sections of the same, forming the pivot axis of the brake spikes.In order to make a simple exchanging of the ski brake (10) possible in the case of this touring binding (2), the invention provides that each bearing is of split design in vertical direction, the lower bearing half (8g) being hollowed out as a depression in an upwardly open recess (8e) of the sole plate (8), and the upper bearing half (10d) being hollowed out in a bearing shell (10c), which can be inserted into the recess (8e) and can be fastened in the latter.
