Definitions

  • the invention relates to a roller skate with an elongated in the running direction Roller frame, a number of one behind the other in the roller frame axles fastened parallel to each other and at least one each swivel-mounted roller.
  • the simplest form of braking device for roller skates is one Stopper mounted on the rear end of a roller skate for braking purposes must be pressed on the floor.
  • Such a braking device offers only one for the roller skater Difficult to control or dose braking, which also also the tilting of the roller skate to be braked around the rear, last axis of a roller or a pair of rollers required.
  • the brake is released by tilting the roller skate around the axis of the rear roller. Even with such braking devices the braking effect is relatively low and by the roller skater difficult to dose.
  • the present invention has for its object a roller skate Generic type to create, which is a simple in structure, in distinguishes their effect very effective and well metered braking device.
  • the braking surface is preferably located on the roller frame attached brake plate can be formed in one of the outside position opposite the roller.
  • rollers are always with slight axial play move automatically in the middle of the axes. This can be encouraged be that the rollers by springs in the middle or at least be pushed away from the braking surface or that the axis and / or the inner surface of the associated bearing bores of the roller Have profiles that push the roller into the center position of the axis.
  • extensive tests have shown that such measures are not absolutely necessary to use the casters during normal use to keep the roller skates in the middle position. Even when cornering the rollers are not, as might be assumed, by centrifugal force pushed into one of their end positions because the runner automatically so laterally that a balance between centrifugal force and Gravity is created and the rollers and axles are only loaded radially will.
  • a displacement of the rollers in an end position on the axis results however, if the runner in the ankles inwards or if necessary also outwards, depending on the arrangement of the braking surfaces.
  • the arrangement of the braking surfaces on the outside of the Rollers proved to be easier on the ankles, since it is easier for the runner to buckle.
  • the rollers on the axles are in that end position shifted in which the braking surfaces are, because the roller skates and especially the axes of the rollers through the Gravity in the downward direction.
  • the runner can achieve a finely adjustable braking effect in this way achieve.
  • the roller frame preferably has an inverted U-shaped cross section, which is open on the lower side and an upper one, in the longitudinal direction of the roller skate directed base plate and two lateral, of this vertically includes downward webs. In these webs are preferred the axes attached.
  • the braking surface can be directly on the inner surface be formed at least one of the webs, or the braking surface can also by a brake plate attached in front of the inner surface of this web be formed.
  • the latter solution is particularly suitable for the Retrofit existing roller skates. For newly made roller skates it will usually be easier to go straight through the braking surface Form a braking surface to form on the inside of the roller frame.
  • the braking device comprises at least one on the extension of at least one roller axle with radial clearance mounted brake roller, the outer diameter of which The outer diameter of the rollers corresponds to that due to the bearing play assumes an inclined position when it comes into contact with the ground, Brake pad of the roller skate frame is pressed.
  • Such a brake roller which is preferably on the outside of the roller frame is arranged, for example in the case of ground contact with the roller frame inclined towards and against a braking surface provided on the roller frame be pressed.
  • a roller skate is generally designated 10.
  • the roller skate 10 is made in the illustrated embodiment from a shoe 12, under which Sole 14 with the aid of screws 16 in the running direction, that is to say from the left to the right in Fig. 1, elongated roller frame 18 is attached.
  • the roller frame 18 has a U-profile open at the bottom in cross section, so that in the The bottom view of FIG. 2 can be seen in the roller frame 18.
  • the U-profile of the roller frame 18 can be seen more clearly in FIGS. 3 and 4. It consists of an upper base plate 20 and two of its side Edges of plate-shaped webs directed vertically downwards 22.24, which is a number of parallel, crosswise and thus Wear axes 26 directed transversely to the roller frame 18. These axes 26 are known per se on the outer sides of the webs 22, 24 by nuts 28 Way releasably set.
  • the nuts 28 can be covered by caps 30 be.
  • a roller 32 is rotatably mounted on the axles 26.
  • Such Rollers are usually made of a flexible material, especially rubber or plastic, and have a bearing bore in a manner not shown used bearing bush made of metal or a harder plastic, which ensures smooth running on axes 26. roller skates of this type are known and require in many different embodiments therefore no further explanations.
  • Brake plate 34 over the entire length of the roller frame 18, and all four illustrated rollers 32 are axially displaceable on their associated axes, may therefore take part in a braking process. However, it was already mentioned that it could be sufficient if only a few rollers and if necessary, only one roller has the braking function.
  • FIGS. 3 and 4 show how the braking effect is brought about can be. It has already been mentioned that during normal running the Set the rollers largely in the middle of the associated axes and thus keep a distance from the brake plate 34, as shown in Fig. 3. In particular, during normal running, the rollers are only radial loaded and not exposed to forces that strive to the rollers to move the axes sideways. This also applies if the runner has one Passes through the curve because it automatically tilts sideways in such a way that a Balance between gravity and centrifugal force. If the runner however, at least one leg in the ankle bends inwards a situation that is shown in Fig. 4 for example for the right roller skate is shown.
  • a spring 36 in the form of a relatively soft Disc spring shown which strives to remove the roller 32 from the brake plate 34 spread so that during normal running there is a contact between the Roller 32 and the brake plate 34 is avoided.
  • FIGS. 5 to 7 A second embodiment will then be described with reference to FIGS. 5 to 7 will. Parts that have already been shown in Figs. 1 to 4 will provided with corresponding reference numerals and not explained again.
  • the two central axes 26 are on one Extended side outside the roller frame 18. These extended sections 38 of the axles 26 take up brake rollers 40 with radial Play on the associated axes are stored, as shown in FIG. 7.
  • a Brake plate 42 On the outer surface facing the brake rollers 40 of the in FIG right side of the web of the roller frame is a Brake plate 42, which is essentially the brake plate already shown 34 can correspond. 6, the brake plate 42 consists of two individual Plate elements, however, this is left up to the expert. Of course, 26 brake rollers can also be used on all four axes 40 may be provided, or on the other hand only on one axis. In each Traps can use continuous, coherent brake plates will.
  • the brake roller 40 can be tilted to the left in accordance with the arrow 44. This occurs, for example, when the brake roller 40 corresponds to the Arrow 46 receives ground contact, as is the case when the runner Roller skate tilted outwards in the ankle.
  • the brake roller 40 in contact with the brake plate 42 so that a braking operation is carried out becomes.
  • the braking effect can be finely dosed by the contact pressure.
  • the outer diameter of the brake roller 40 corresponds essentially to that Outer diameter of the roller 32. However, it may be advantageous to use the outer diameter the brake roller slightly smaller than that of the rollers choose so that unwanted braking even with a slight inclination of the Roller skate is avoided.
  • the brake rollers 40 can on the surface that with the brake plate 42 comes into contact when braking, be provided with a lining 44, which is possibly embedded in the brake roller and can serve the braking effect and / or to increase the durability of the brake roller 40.
  • the outer section 38 chamfer the axis 26 on one side like a cone. This is an end position of the braking effect is possible. Is the beveled Area of section 38 below, is the largest tilt angle of the brake roller and thus the greatest braking effect possible. If the axis is rotated by 180 °, the lateral surface running parallel to the longitudinal axis lies below, and the most tapered area of the axis is at the top. In this case the brake roller can be inclined only slightly, so that a lower braking effect entry. All intermediate positions are possible between all end positions.
  • the brake rollers 40 are located in each case on the outside of the roller frame 18, that is to say on the right roller skate outside right and left outside with the left roller skate. This will avoid that the brake rollers on the inside of the feet inadvertently against each other bump. But it is also possible, especially when using Brake rollers of smaller dimensions to arrange the brake rollers on the inside.
  • the brake plates 34 and 42 can on the Roller frame glued or otherwise permanently attached, and they can also be detachably attached, for example by screws or the like. If necessary. they can also be mounted on the axles.
  • Advantageous is in any case an easy interchangeability and the possibility of existing Retrofit roller skates.
  • the braking device according to the invention is not only for the here in detail treated inline skates, but also for roller skates with several, Roller pairs arranged side by side applicable.
  • the brake plates 34, 42 can with heavy loads with cooling devices, for example, cooling fins.
