  • At least two of the transmission arms 11, 12 can be fastened in at least one on the sports device 2 arranged hinge arrangement 14, 15 in one or more in the direction of Pivot axes 18, 20 of the joint arrangements 14, 15 spaced apart and to these vertical vertical plane (s) 9 in the further of the sports device 2 opposite end regions in the other in the longitudinal direction - arrow 66 - of the foot to each other distanced and connected to the contact surface 7 hinge arrangements 13, 16 articulated.
  • Joint arrangements 14, 15 are the transmission arms 11, 12 relative to Footprint 7 inclined and extending e.g. from the mid-range between the hinge arrangements 13, 16 in opposite directions of the longitudinal extension - Arrow 66 - of the foot.
  • the front joint arrangement related to the usual direction of travel - according to arrow 10 13 on the contact surface 7 is thus with the transfer arm 11 in Articulated connection, which is contrary to the usual direction of travel - according to Arrow 10 - extends to the sports equipment 2 arranged below and with it the hinge assembly 14 is articulated.
  • Transmission arms 11, 12 pointing in the same direction or exactly parallel to one another aligned transmission arms 11, 12 represent a rather unsuitable training
  • the transmission arms 11, 12 the sloping legs and the sports equipment 2 and the footprint 7 would form the base or top edge would be a for the user Swiveling up the heel area compared to the toe area is difficult.
  • the locomotion energy to be applied by the user through muscle power would be converted to potential energy to a high percentage, in order to be able to overcome the top dead center positions of the pivot axes 17, 19.
  • the movement energy provided by the user would therefore be a certain percentage into a vertical movement irrelevant to the speed of travel of the foot relative to the sports equipment 2.
  • the transmission arms 11, 12 are assigned to the two longitudinal side areas of the shoe, so that a total of four transmission arms 11, 12 are formed.
  • the holding extensions 123, 124 preferably overlap the im Cross-section essentially U-shaped chassis frame 121, so that overall a relatively low height of the roller skate 119 can be achieved.
  • the length dimensions 23, 24 of the transmission arms 11, 12 can be about 20% to 200%, preferably 70% to 120% of the sole length of the footwear.
  • arcuate rolling surface 126 may be arranged, the automatic lowering of the Toe area of the foot in the direction of the sports equipment 2 prevented and always a linear Contact between the sole of the shoe and the sports equipment 2 guaranteed and thus supports the hinge assemblies 13 to 16 or from excessive Stress protects.
  • the rolling body 125 can also be used as Damping element 95 act, which dampens the rotational and translational movement when the maximum swivel angle is reached.
  • the stop element 48 which lowers the heel region of the Sports shoes limited in the direction of the sports device 2 can - as shown in Fig. 7 - through the heel of the sole or also through the journal 28 of the joint arrangement 16 be formed.
  • the spring means 117 are also preferred in the embodiment shown in FIG. 7 provided which the sports shoe with a certain spring force against the sliding or Press roller 3, 5 and only after exceeding a certain, from Swiveling force to be applied by the user is a swiveling of the contact surface 7 enable in relation to the sliding or rolling body 3, 5.
  • the connecting device 1 thus forms a releasable binding for the Foot of a user on the sports device 2 and is preferably attached to it adjustable.
  • the shoes described above each have suitable elements, such as the grooves 82, 83, via which the receptacle of the joint arrangements 13, 16 of the Connection device 1 is possible.
  • those previously described Sports equipment 2 elements such as the mounting surface 30 for receiving at least one of the joint arrangements 14, 15.
