Definitions

  • the invention relates to a ski brake with a base plate to be fastened to the ski and with a foot plate articulated on it by means of a transverse axis and acting under the action of a positioning spring, on which two brake mandrels with their cranked sections opposite and arranged parallel to the brake blades whose axes are pivoted in two bearings.
  • ski brakes of this type were somewhat complicated in their construction in that a total of four resilient elements were required to pivot and return the two brake mandrels about their axes. Furthermore, the pivoting was brought about by the fact that extensions of the sections of the two brake mandrels mounted in the tread plate came to rest on leaf springs or resilient flaps which were pivoted against the tread plate when it was depressed and thereby rotated the named sections by a predetermined angle.
  • the aim of the invention is to eliminate these disadvantages and to create a ski brake of the type mentioned at the beginning, in which each brake paddle travels a precisely defined pivoting angle even after prolonged use and in which, in the event of a bending of the brake mandrel, the start of the pivoting process is within certain limits can be changed.
  • the axial adjustment of the two nuts can take place, for example, in that a control cam which is fastened to the base plate is provided as the control member, the region of which facing the transverse part is chamfered in the direction of the pedal plate being depressed.
  • the displacement of the nuts and thus also the swivel angle of the brake mandrels is defined on the one hand by the stop or stops and on the other hand by the point at which the control edge of the cross member abuts the control cam when the tread plate is depressed.
  • control member is designed as a flap which is articulated on the free end of the tread plate, this flap carrying a control cam running in the cross-ski direction, which is designed with a bevelled surface for contact with a control edge or curve of the cross member.
  • the flap can advantageously be arranged on the underside of the tread plate and - in the pivoted-down position of the tread plate - be supported with one end on the base plate or on the top of the ski, or the flap, which, under the influence of a pushing it against a stop Standing spring stands, can, at least in the braking position, pass through a recess in the tread plate with its control cam and can be pivoted toward the cross part by the ski boot of the user when the tread plate is swung down.
  • the shifting of the two nuts with steep thread takes place in that at least one pair of toggle levers is arranged as a control member on the underside of the tread plate, one lever at the free end of the tread plate and the other lever at the cross part or on the nut is articulated and its knee joint comes to rest on the base plate or on the top of the ski when the step plate is swung down.
  • the force with which the two brake blades are pressed into their driving position is particularly great due to the toggle action.
  • each nut is on the side remote from the transverse axis of the tread plate has a transverse, preferably flat side surface inclined at an angle to the brake arbor axis, to which a corresponding control surface on the tread plate serving as a control element is assigned, with the tread plate depressing when the tread plate is depressed slide the control surfaces together and press each nut back against the force of the associated spring towards the tread plate and its transverse axis.
  • a kind of wedge effect is created, so to speak, when the tread plate is depressed between the nut and the tread plate, by means of which the adjusting force resulting from ski boots is considerably increased.
  • each nut has a cam-shaped extension on the end carrying the control surface, which is intended to rest on the base plate or on the top of the ski.
  • the intended adjustment path of the two nuts is reliably maintained even if certain signs of wear have already occurred on the base plate or on the top of the ski as a result of use.
  • nuts and brake mandrels are simultaneously adjusted in opposite directions. This is done in that an arc-shaped leaf spring is provided for each brake mandrel or for both brake mandrels, of the two ends of which protrude upwards in the braking position, one on the associated nut or on a cross member connecting the two nuts, and the other on a support body attacks which, like the nut (s) on the tread plate is guided in its longitudinal direction, but is secured against rotation.
  • This design has the advantage that, due to the opposite adjustment of the support body and nut, the swivel angle of the tread plate required for pivoting the two brake blades against the longitudinal plane of the ski is approximately halved with the same pitch of the steep thread.
  • control member in another embodiment, it is also possible to design the control member as a control cam and to fasten it to a lever, the pivot axis of which is formed by the transverse axis of the tread plate.
  • each steep thread can be formed by two diametrically arranged grooves, which are delimited at least on one side by a helical surface and into which two correspondingly shaped lugs of the narrow side of the tread plate, which run in the direction of the sections of the brake spikes, protrude, the steep threads preferably are provided in cylindrical plastic extrusions of the two brake mandrel sections. In this way it is possible to produce the high helix thread by injection and not by machining.
  • Another embodiment is characterized in that the two nuts are fastened to the underside of the tread plate close to their transverse axis, that a control mechanism is provided that counteracts the force of each brake arbor immediately before the tread plate rests on the base plate or on the ski top pushes the spring back.
  • This version has the advantage over the ski brakes dealt with first that each brake mandrel is held in the immediate vicinity of its transverse section connecting the two parallel sections, which significantly reduces the torsion angle with the same torque acting on the brake paddle and the same mandrel diameter.
  • transverse axis engages in an annular groove of each brake mandrel to secure the brake mandrels against axial displacement, and if the displacement path of the tread plate by means of at least one elongated hole, preferably arranged in an attachment on its underside, parallel to the plane of the Tread plate runs, and which is penetrated by the transverse axis, is determined.
  • the transverse axis is used simultaneously for three functions, namely as a swivel axis, as a securing element against axial displacement of the brake mandrels and as a guide element for the tread plate, which results in great savings.
  • the elongated hole of the tread plate it is not absolutely necessary for the elongated hole of the tread plate to be provided in an extension thereof. Rather, according to a further embodiment, it would be entirely possible to arrange the bearing block or the bearing blocks for the transverse axis at a distance from the lateral boundary edge of the base plate and to leave out the elongated holes in the side walls of the approximately bowl-shaped step plate.
  • control cam it is not necessary for the control cam to extend over the entire width of the base plate. Rather, it is quite sufficient if the control cam is arranged only in the central region of the base plate and protrudes into a groove in the step plate, the groove ending in a control surface for the control cam. In this way, the control cam is used not only to control the rotary movement of the brake mandrels, but also to guide the tread plate laterally during the control process.
  • leg springs are arranged on the individual sections of the brake mandrels mounted on or in the tread plate, said leg springs pressing the transverse brake mandrel sections against the helical surfaces.
  • the step plate itself.
  • it could be flat and carry lugs in which the slots or helical surfaces are provided.
  • a particularly economical solution in terms of manufacture is characterized when the tread plate is approximately bowl-shaped, the side faces of the tread plate adjacent to the ski side faces - viewed in cross section - running along quarter arcs, the center points of which are formed by the axes of the brake mandrel sections mounted in the tread plate.
  • This design has the advantage that the transverse brake mandrel sections are supported directly next to the ski side surfaces, which prevents the occurrence of undesirable vibrations during the braking process.
  • At least one stop is arranged on the underside of the tread plate to limit the displacement of the cross member or the brake mandrels under the influence of the spring or springs. In this way, the swiveling path of the two brake mandrels is reliably limited and the transverse brake mandrel sections are prevented from sliding out of the slots at the same time.

  • the tread plate which is generally made of a plastic material, receives threaded sleeves made of metal, which are inserted and held in holes in the tread plate by means of a press fit.
  • guides can be provided in the base plate according to FIGS. 18-20, by means of which the step plate is displaced away from the transverse axis with positive locking. In this case, however, friction members would have to be arranged which prevent a relative movement between the brake mandrels and the step plate during the pivoting movement of the step plate.
  • the base plate does not necessarily have to be fastened to the top of the ski with screws. It can also be adjustable and ascertainable in a guide attached to the top of the ski in the longitudinal direction of the ski. This applies to all exemplary embodiments. Furthermore, compression springs and vice versa can be used instead of tension springs if the construction is appropriate.
  • So-called set-up springs are usually used to actuate ski brakes, which always try to pivot the braking device, which has the step plate or the like and the brake mandrels, into the braking position.
  • Such springs are generally designed as leg springs, as torsion springs or as leaf springs.
