Definitions

  • the invention relates to a roller skate body with a sole plate designed for attachment to a shoe sole, from which four supports extend downwards in pairs, and with two rollers arranged one behind the other in the running direction between the two supports of a pair of supports in a common central longitudinal plane of the roller skate base and are rotatably mounted.
  • Such a roller skate body is known from DE 26 19 206 AI.
  • roller skate bodies which have only two rollers arranged one behind the other in the running direction, a driving behavior is to be achieved which largely corresponds to that of an ice skate.
  • Conventional roller skates which have a pair of front rollers arranged side by side and an equivalent pair of rear rollers, cannot achieve skate-like driving behavior, because when cornering an incline like a motorcycle turning a corner is practically impossible.
  • An inclined position is possible in the known roller skate base body of the type mentioned, but this one is missing another property which is essential in ice skating, which is referred to below as "transverse braking ability".
  • Cross-braking is the process that, for example, ice hockey players perform when braking at full speed, if they place the skate crossways to the running direction and let it slide over the ice surface in order to achieve the shortest possible braking distance.
  • the skate is also tilted.
  • roller skate base body known from DE 26 19 206 AI which has a continuous sole plate, nor with other known roller skate base bodies, transverse braking, which is an essential element of ice skating, is possible, since the known roller skate base bodies are those used for cross braking do not withstand the loads that occur, but twist or bend, which can lead to a fall.
  • the invention has for its object to develop a roller skate body so that a transverse braking is possible.
  • the diameter of the rollers is preferably over 70 mm, for example in the range from 70 mm to 100 mm.
  • a roller diameter of approximately 90 mm is particularly preferred since large diagonal positions are possible with this diameter and the forces acting on the feet of a user during transverse braking are absorbed so well that surprisingly even inexperienced users are able to steer and brake particularly safely.
  • the larger diameter of the rollers compared to conventional roller skates allows the resulting greater distance between the ground and the sole surface to bend the roller skate into larger inclined positions, such as are required for skating-like cornering and transverse braking.
  • the rollers have treads of a substantially semicircular cross section. This ensures a well-controllable driving behavior, even in an inclined position, with good transverse braking properties at the same time.
  • the cross section of the treads can also be semi-elliptical.
  • the rollers preferably have rims made of dimensionally stable material and running surfaces made of elastic material.
  • the dimensionally stable material can be, for example, a sufficiently hard plastic or metal, for example an aluminum alloy.
  • the elastic material of the treads for example rubber or a suitable plastic, ensures good adhesion to the surface, ensures quiet rolling and can be optimized for the best possible transverse braking properties.
  • the running surface can expediently be exchanged in order to enable replacement in the event of wear or also adaptation to different roadway surfaces.
  • the axis of rotation of the rear roller in relation to the running direction is arranged behind the area of the sole plate which is assigned to the center of the heel of a user.
  • the pressure exerted by the heel on the sole plate during transverse braking can thus be better transmitted to the rear roller, since the risk of tipping over the rear roller is reduced. This arrangement also leads to an overall more stable driving behavior.
  • the axis of rotation of the front roller in relation to the running direction is arranged in or in front of the area of the sole plate which is assigned to the ball of the foot of a user.
  • the turning axis of the rear roller is arranged behind the center of the heel in relation to the running direction and the axis of rotation of the front roller is arranged in front of the ball of the foot.
  • the distance between the surface of the sole plate and the front axis of rotation is less than the distance between the top of the sole plate and the rear axis of rotation. Assuming the same outer diameter of the two rollers, the front part of the sole plate is lower than the rear part.
  • a shoe can be attached to the base of the roller skate, for example by screwing, riveting, gluing or in some other way. It is only important that a strong, play-free connection between the shoe and the roller skate body is made.
  • the sole plate, the supports and the web connections together form a one-piece frame component.
  • such a one-piece frame component can also be produced inexpensively by a casting or spraying process and can be provided with an aesthetically pleasing shape without additional effort.
  • the sole plate of the skate body can be interrupted or continuous.
  • Fig. 1 is a side view of an inventive
  • FIG. 2 the associated view from below and FIG. 3 the section along the line III-III in FIG. 1.
  • the skate body 10 shown in FIG. 1 has an interrupted sole plate with a lower front sole plate part 12 and a higher rear sole plate part 12 '.
  • a shoe (not shown) can be fastened to the soleplate 12, 12, for example by screwing or gluing.
  • Two supports 14 protrude at right angles from the front part 12 of the sole plate 12, 12 'in relation to the running direction A when driving forward.
  • two further supports 16 extend parallel downward from the rear part 12 'of the soleplate.
  • the supports 14 and 16 lying on a common side of the vertical central longitudinal plane M are each connected to one another by a web 18.
  • the sole plate 12, 12 ', the front supports 14, the rear supports 16 and the two webs 18 form a one-piece frame component in the embodiment shown, which is symmetrical to the central longitudinal plane M.
  • a roller 20 is mounted between the front supports 14 and a roller 22 is rotatably supported between the rear supports 16.
  • the axis of rotation V of the front roller 20 lies approximately below the center of the foot of a user or somewhat in front of it in relation to the direction of travel A.
  • the axis of rotation H of the rear roller 22 is arranged such that it is located behind the center of the heel of a user in relation to the direction of travel A.
  • the two webs 18 bridge the space between the two rollers 20 and 22 and lie in this entire space below the common plane of the turning axes V and H.
  • FIG. 3 shows, using the example of the front roller 20, its rotatable mounting between the supports 14.
  • the roller 20, like the roller 22, has a hub 24 with a continuous axial recess 26.
  • a ball bearing 28 is arranged in each of the end extensions of the recess 26.
  • An axis 30 extends through the recess 26 and the two ball bearings 28, the ends of which are each fastened in an opening 32 formed in the supports 14.
  • the length of the axis 30 corresponds to the distance between the outer sides of the supports 14.
  • a threaded hole is formed in each of the end faces of the axis 30, into which a screw 34 with a wide, flat head is screwed in order to move the axis 30 in the axial direction fix.
  • each of the rollers 20, 22 has a race made of elastic material, which has a tread 38 of a substantially semicircular cross section.
  • the race can, for example, be vulcanized or glued on, but it can also, as indicated in FIG. 3, be fastened to a rim 40 by a tongue and groove connection, so that if the tread 38 is worn, only the race and not the entire roller must be replaced.

Abstract

Le corps de base d'un patin à roulettes (10) comprend une plate-forme (12, 12') d'où quatre supports (14, 16) disposés par paire partent vers le bas. Entre les deux supports de chacune des paires (14, 16) est logée une roulette (20, 22) de 70 à 100 mm de diamètre, de manière que les deux roulettes (20, 22) en totalité soient disposées l'une derrière l'autre dans un plan longitudinal médian commun (M) du corps de base du patin à roulettes (10). Les supports (14, 16) qui se trouvent de part et d'autre du plan longitudinal médian (M) sont reliés entre eux par une traverse (18) dont l'écartement par rapport à la surface de la plate-forme (12, 12') est plus important que celui qui sépare la surface de la plate-forme des axes de rotation (H, V) des roulettes (20, 22).
