Definitions

  • the invention relates to a braking device for a, preferably single-track, roller skate with rollers arranged one behind the other on a carrier, a brake pivot lever which can be actuated via the shoe upper or shoe neck of the roller skate, and a brake pivot lever which can be displaced in the longitudinal direction of the carrier and act on one or more of the rollers Brake slide, the carrier being connected or connectable to the shoe part of the roller skate on the underside thereof.
  • Braking devices for single-track roller skates are of great importance for the safety and comfort of the user.
  • braking devices are also important for all other participants in traffic because their safety is also affected.
  • the previous solutions are not a really satisfactory situation, because they are either not effective enough in the braking effect, require an unstable posture to operate them, they can be triggered unintentionally because, if the rollers are braked cause excessive abrasion or because they are often too complicated from a production point of view and are therefore too expensive.
  • roller skates there are various braking systems, most of which act on the running surface, i.e. on the floor, but partly also on the rollers.
  • the present invention relates exclusively to braking systems which act on the rollers or possibly wheels, the braking process being able to have an effect when only one of the rollers is braked.
  • it will make more sense in the majority of cases to let the braking device act on at least two or three rollers, and it is generally advantageous not to brake the last roller, since many roller skaters do it by the brake systems that are still in use are used to lifting the roller skates when braking, and as a result the braking would only take effect on the last roller, especially with an unfavorable, unstable posture.
  • the result of such braking will then very often be an undesirably strong abrasion of this role, which subsequently quickly becomes inoperable which can cause a significant impairment of the overall driving and braking properties of the single-track roller skates.
  • the conversion of a rotary movement by deflection into a translational movement represents an ideal basis for deriving a trigger mechanism for a braking system.
  • the anatomical facts explained below can be used.
  • the lower leg In an upright position, the lower leg is essentially a vertical position and the lower leg is in a substantially 90 ° position with respect to the foot.
  • the lower leg In each crotch position, the lower leg, which rotates in relation to the foot at the ankle, moves further back (the angle between the sole of the foot and the front of the lower leg becomes greater than 90 °) the larger the crotch position is selected.
  • the shaft follows this automatic pivoting movement of the lower leg, the shaft also moves backwards in the area above the ankle. It is not important whether the shaft is connected to the shell by means of a joint or not.
  • shoes in this embodiment as well as shoes which are connected to the shell by means of a swivel joint, are well known.
  • this braking device only includes the possibility of using shoes whose shaft are connected to the shell by means of a swivel joint, or in which at least a cuff-like stiffening is provided on the shaft for the purpose of transmitting the shaft movement to the transmission member.
  • a one-sided lever is used, which has a swivel joint at its lower end, which is rotatably supported on the roller mounting frame.
  • the braking result is considerably restricted by the reverse effect, namely that the slider is pushed away from the rotating rollers or wheels by a constantly renewing stretch of track, which in turn is the intention of a well-functioning braking device contradicts.
  • a linkage at axle height results in the mutual abolition of the two effects mentioned and thus by far the best braking result, with a further enlargement or reduction of the contact surface, which comes to lie above or below the roller axis plane, a further targeted adjustment to the desired Braking effect is possible.
  • the guidance of the brake slide at the rotating axis height is also important for reasons of the strength and reliability of the braking system, because the stability of the frame is particularly high, especially at the height of the axis, due to the usually bolted axes.
  • the object of the invention is therefore to make maintenance of the roller skate as simple as possible and the easiest possible replacement of rollers.
  • Another object is to provide a braking device that enables safe braking for the roller skater. It is also a task to achieve the most uniform possible load on the roller skate during the braking process.
  • the actuating distance of the braking device is too short, the desired braking effect either does not occur at all, or the braking device is only an extremely short distance from the rollers or wheels when not actuated.
  • the latter harbors the risk that an undesirable braking effect can occur due to slight soiling (tiny stones that stick to the rubber of the rollers), which creates a safety risk. It is therefore very important to be able to determine the length of the force arm and load arm of the lever by varying the height of the shoulder of the axis of rotation.
  • Another object of the invention is therefore to provide a braking device with which a suitable dosage of the braking force applied can be achieved.
  • Another object of the invention is therefore to provide a braking device with which problem-free walking and climbing with roller skates is possible.
  • the brake pivot lever is formed from at least one actuating arm and at least one engagement arm which is in operative contact with the brake slide, preferably butt contact, in that the pivot axis of the brake pivot lever is arranged on the carrier or on the shoe part of the roller skate, the free one End of the actuating arm is pivotable by movement of the shoe upper or shoe neck, and that the brake slide is essentially displaceable in the plane spanned by the roller rotation axes.
  • the freedom of movement of the roller skater is substantially increased because the brake pivot lever does not have to be pulled when the shaft moves forward, which is very important for the free movement of the skater.
  • the transmission mechanism is automatically triggered from a certain degree of pivoting of the shaft, as a result of which this transmits the applied force to the brake slide.
  • a shorter power arm and thus also a larger actuation distance of the brake slide is provided, and the starting height of the swivel lever axis can be set as desired.
  • the swivel axis is formed from two or more swivel bearings arranged in alignment.
  • the pivotable mounting can also be realized by pivot bearings provided on opposite sides, so that no continuous axis of rotation is required.
  • the brake slide is formed from a frame, each of which has at least one contact surface in the area of one or more rollers, preferably except for the rearmost roller of the roller skate, which, when the brake pivot lever is actuated, moves from a released position into a braking position System with the adjacent roller surfaces adjacent to the rolling surfaces or braking surfaces attached to them, e.g. Brake discs, can be brought or are.
  • the actuating arm and the engagement arm are rigidly connected to one another in the region of the pivot axis of the brake pivot lever, which results in a very simple possibility of transmitting power from the shoe upper or shoe neck to the brake slide.
  • an actuating arm which can be pivoted independently of the attack arm and of the actuating arm, preferably about the pivot axis of the brake pivot lever, is provided, which rests with its free end on the displaceable brake slide and which has an adjusting element, preferably an adjusting screw , is in active contact with the attack arm so that when the attack arm pivots, it presses the free end of the actuating arm against the displaceable brake slide.
  • the attack arm is approximately half as long as the actuating arm, since in this case there is a particularly advantageous power transmission and adjustment option.
  • a two-armed actuating arm is provided which can be pivoted independently of the attack arm and the actuating arm, preferably about the pivot axis of the brake pivoting lever and which has one free end in abutting contact with one end of the displaceable brake slide, and the Via an adjusting element, preferably an adjusting screw, is in operative contact with the attack arm and an eccentric head of an eccentric pivoting lever is articulated at the second free end thereof, which by pivoting into its eccentric position keeps the attack arm with its eccentric head permanently in the braking position of the brake slide.
  • the attack arm can have a plurality of spaced-apart, edge-open incisions along its longitudinal extent.
  • the actuating arm is formed from two articulated parts, the end of one actuating arm part being extended beyond the articulation point and the end of the arm extension resting on an elastic tongue molded onto the other actuating arm part, which is initially elastically deformable when the actuating arm is pivoted before the frictional connection between the actuating arm parts is established. In this way, very effective damping of the power transmission from the shoe upper or shoe neck to the brake slide can be achieved.
  • the brake slide should also be able to be pressed firmly onto the rollers for the purpose of determining the rollers.
  • the conditions to be taken into account are essentially the following:
  • the pressure on the brake pusher must be so firm that the rollers are reliably clamped between the contact point and the roller axis. This criterion requires effective leverage of the force used.
  • the lever that causes the pressure must be firmly in the position in which it is locked, otherwise an unintentional release can occur, which would endanger the skater, who was just climbing the stairs.
  • the locking device should be effective for different reel sizes and shapes, so that the brake slide or other parts do not have to be replaced when using a different reel type. This also applies to the adjustability of the release lever. This must also include a sufficiently large scope, if possible.
  • an adjustment device also enables an optimal adjustability of the triggering lever for the purpose of adapting to different thicknesses of the lower leg and an exact adjustability of the triggering time.
  • an additional brake slide independent of the brake slide preferably with two wedge-shaped contact surfaces, is arranged in the area of the rearmost roller, and that both the brake slide and the additional brake slide are displaceable via a swivel lever, so that in the eccentric position of the swivel lever, the contact surfaces of the additional brake valve and the contact surfaces of the brake valve are permanently held in the braking position.
  • the brake slide and the additional brake slide are arranged displaceably in one plane. This makes it possible to use a very simple sliding mechanism for the locking of the rollers.
  • an eccentric wing disc is arranged so as to be pivotable about a pivot axis, preferably parallel to the axis of rotation of the rollers, the eccentric wing disc in the eccentric position of the eccentric pivoting lever enlarging and increasing the mutual distance between the brake slide and the additional brake slide the mutual distance is reduced in the free position of the eccentric pivoting lever.
  • the eccentric wing disc enables the rollers to be locked very effectively in the braking position.
  • the eccentric vane disk can have straight snap-in areas in its eccentric position. This prevents the eccentric vane from automatically slipping out of the fixed braking position of the rollers.
  • an adjusting mandrel with wedge-shaped lugs is displaceably guided transversely to the direction of displacement of the brake slide or additional brake slide, and that the adjusting pin is articulated to the head of the eccentric pivot lever via an actuating pin which is guided through the carrier wall, whereby in the eccentric position of the eccentric pivot lever, the wedge-shaped lugs are pressed against opposing contact surfaces of the brake slide and the additional brake slide, so that they are permanently held in the braking position.
