Inline skating as a sport is enjoying increasing popularity and has meanwhile developed into a popular sport. In 1996, 4 mil lions sold almost as many inline skates as motor vehicles registered (Jerosch, J. et al .; TW Sport + Medizin 9 (1997), 118 to 123). Unfortunately, this sport is one of them  most injurious sports ever. According to the literature (Jerosch aaO; Einartner C. et al .; Sports publishing, sports damage. 11 (1997), pp. 48 to 51; Jerosch, J .; Knee Surb Sports Traumatol Arthrosc. 1998; 6 (1): pp. 44 to 49; Largiader, U. et al .; Switzerland Rundsch Med practice. 18 (Feb. 1998); 87 (88), pp. 259 to 262; Goh, S.H. et al .; Ann Acad Med Singapore, 1996; 25 (4): pp. 547 to 549; ) about 40 to 60% of inline skaters experience one Injury. For example, there are 60,000 accidents a year in Switzerland that involve inline skating are bound (Largiader loc. cit.). About 40% of the injured need special medical care Help, outpatient or inpatient. In many cases, these injuries lead to several weeks therapies lasting several months and correspondingly long periods of incapacity to work. About 80% the injuries affect the arms and head and 20% the legs (Jerosch 1998, op. cit.). In principle, three mechanisms lead to injury (Goh, loc. Cit.). Most injuries arise when falling forward. Wrists (dislocations, strains, frak doors), elbows and forearms injured. Falling backwards is the most common Head injuries. The third mechanism, though not the most common, is consequential the severity of the injuries is the most significant and is due to a rotational movement of the body with a fixed, strained foot. This leads to an explosion in the upper jump joint with complex ligament and ankle injuries, lower leg fractures, complex Knee injuries and fractures of the femoral neck.

The invention is based on the finding that the movement sequences when driving with Inline skates, roller blades or roller skates as well as the basic injury mechanisms are different from, for example, those in alpine skiing or in Ice scating. When riding with inline skates and the like there is an intense one Contact between the rubber of the wheels of the inline skates and the asphalt, what with one very high frictional resistance goes hand in contrast z. B. for skating, where the contact surface is more or less convex and is therefore significantly smaller. In as a result of this intensive contact, rotary movements with considerable torques are ver bound, which leads to injuries that, according to the biomechanical principle, this always take place at the weakest point. This is typically the upper ankle, although there are injuries to the lower leg, knee and neck can be conditioned by. Unlike in alpine skiing, they play with inline skates Bending forces don't matter. Accordingly, they are particularly practiced in alpine skiing safety devices or binding systems for driving with inline skates, scooters blades or roller skates not applicable. With the binding system according to the invention, which could also be called rotation protection in connection with the invent shoe according to the invention and in particular also with the inline skates according to the invention, Rol Blades or roller skates can significantly avoid or reduce the risk of injury be, because when a critical torque of the shoe out of the frame, the typically carries the binding system and is connected to the necessary chassis, triggers.

In addition to this aspect, another advantage is that unexpected, critical Situations of this binding system by abruptly rotating the legs, disengaging d. H. separation of the frame supporting the chassis from the shoe, and braking with the shoes. This aspect is not insignificant insofar as that from Stu  It is known that many inline skaters are unable to brake properly. Rather, in 26% of the inline skaters surveyed, this is only because they are hold onto solid objects or intentionally fall (Jerosch, 1997, loc. cit.).

In the binding system according to the invention it can be provided that the fixing element ment can be deflected laterally either in the heel area or in the toe area, with the It is possible that the fixing element can be deflected laterally in both areas. In the case of lateral deflection of the fixing element in the toe area, there is a Advantage in that a longer lever can be realized, which has a lower lateral front Tension required and thus a small dimensioning of the fixation element forming parts allowed.

The term inline skates should be used in connection with the present application stand that it also includes roller blades and roller skates. To this extent, the invention Binding system also for these sports equipment and essentially conceptual or construction the same sports equipment is used. Furthermore, the term inline skating is intended here the singular of the term "inline skates" can be understood, d. H. a piece of a pair Denote inline skates.

In the inline skates, roller blades or roller skates as well as the shoe According to the invention it can be provided that the fastening elements for the heel and the toe area is releasably attached to the shoe body. Specifically, this can be, for example se done in that the fasteners, typically fastening teeth, in the shoe according to the invention are screwed in or fastened with a clip mechanism.

In the inline skates proposed by Rol in the second alternative lerblades or roller skates around a shoe and a frame supporting the chassis grasp, the shoe a shoe body and a bin connected to the shoe body expansion system according to the invention, the frame, the fasteners for the Fer Sen- and toe area includes and the fasteners with the shoe body  connected binding system, it is a kind of Reverse the arrangement of the fasteners and the fixing elements relative to one another at the. In the first alternative, as explained in the examples, are the attachments elements formed in the form of fastening teeth on the shoe body. The fixation however, elements are located on the frame that encompasses the chassis. The second The fastening elements are alternative, again preferably in the form of fastening teeth, attached to the frame supporting the chassis and the shoe body, in particular its sole has the fixing elements for the toe and heel area.

Further embodiments and specific embodiments of the invention will follow explained with reference to the figures, wherein

Fig. 1 shows an inline skate according to the invention, which comprises the binding system according to the invention together with the shoe according to the invention;

Fig. 2 is a partial view of a section along the longitudinal axis of the inline skate, showing the fixing element in the heel area;

Fig. 3 is a schematic plan view showing the fixing element in the heel region;

Fig. 4 is a schematic partial view of a section along the longitudinal axis of the in-line skate, showing the fixing element of the in-line skate in the toe area;

FIG. 5 shows a plan view of a section through the fixing element in the toe region in the plane AA ′ of FIG. 4;

FIG. 6 shows a plan view of a section in the plane BB ′ of FIG. 4 through the fixing element in the toe region; and

FIG. 7 shows a plan view of a section through the fixing element in the toe region in the plane CC ′ of FIG. 4.

Fig. 1 shows an inline skate 1 according to the invention, which shows the binding system according to the invention together with the shoe 3 according to the invention. Inline skate 1 also shows the components customary for inline skaters, in particular the chassis 7 consisting of a plurality of wheels 5 , which is attached to a frame 31 , and a braking device 9 . The binding system consists of the fixing element for the heel area 11 and the fixing element for the toe area 13 .

FIG. 2 shows a schematic partial view of a section along the longitudinal axis of the inline skate, which shows the fixing element for the heel area 13 .

The fixing element for the heel area 11 consists of a biasing means 15 and a deflection means 17 . Biasing means 15 in turn consists of a ball, in particular steel ball 19 and a spring 21 , which is attached to a bearing point 23 . The bearing point 23 in turn is part of the regulating screw 25 , with the aid of which the pretensioning of the pretensioning means is adjusted according to the needs of the user. On the one hand, this preload ensures a stable connection in normal driving style and, on the other hand, the disengagement when a critical torque is reached. The preload should depend on the stability of the user's support apparatus, which is determined, for example, on the basis of the shin condyle diameter or circumference of the instep. Additional securing in the sagittal plane is not necessary here, since the bending forces are relatively low with a short contact area.

In the present case, this type of fixation element is arranged in the heel area, depending however, it is conceivable that this can also or additionally be arranged in the toe area. However, the arrangement shown is advantageous in that a fei in the heel area nere power adjustment is possible and in general there is a better space prevails.  

As a result of the spring action, starting from the bearing point 23 , ball 19 is moved in the direction of the toes and in this respect has a contact surface with the rear fastening tooth 27 , which is located on the sole of the shoe body 29 and presses it against deflection means 17 and thus a releasable connection between the shoe 3 and the chassis 7 , including wheels 5 , supporting frame 31 creates. In the present case, part of the fixing element for the heel region 13 can thus actually be deflected, namely deflection means 17 .

Deflection means 17 in the embodiment of the invention shown in FIG. 2 has a two-part structure consisting of two lateral limiters 33 , 33 '.

The rear fastening tooth 27 has, at its end facing the prestressing means, with an otherwise essentially rectangular cross section, a step 35 which serves to anchor the fastening tooth 27 . In this respect, the cross section of the fastening tooth is larger at its free end than in the area of the transition from the fastening tooth to the shoe body. For this purpose, plate 37 is provided, which opens resiliently when fastening tooth 27 is inserted. Plate 37 is attached to the frame 31 via axis 39 , a spring 41 ensures that after the insertion of fastening tooth 27 in the fixing element for the fer senbereich 11 closes the plate and engages with stage 35 and thus fastening tooth 27 in the bearing against in Sagital forces stabilized.

Fig. 3 shows a schematic plan view of the fixation element for the toe portion 11. Deflection means 17 is formed in the present case by two lateral limiters 33 and 33 ', with each lateral deflector having a spring mechanism 43 , 43 ' associated with it, which means that a certain torque for deflecting the lateral limiter is required. The force required for deflection can be adjusted by a regulating screw 45 , 45 'to the respective requirements. In the present case, the limiters 33 , 33 'are connected to the frame 31 via a common axis 47 . The rear fastening tooth 27 has a substantially rectangular cross section, the corners being rounded in order to adapt to the shape of the lateral limiters 33 , 33 '.

FIG. 4 shows a schematic partial view of a section along the longitudinal axis of the inline skate, which shows the fixing element for the toe region 13 . The fixing element for the toe region 13 is essentially formed by a recess 49 which has a step 51 in such a way that the width W of the fixing element or, when viewed from above, the cross section for the toe region and in particular recess 49 in the direction of the shoe body 29 is reduced. Corresponding to this stage, the front fastening tooth 53 has a nose 55 which understands stage 51 . When the front fixing tooth 53 inserted as intended in the fixing element for the toe area 13 and in a grip passes, wherein, not shown, the rear fixing tooth 27 with the fixing element engages for the heel region 11 of the shoe body, as a result of the biasing means 15 29 relative moved to the frame 31 in the direction of the toes with the result that a non-positive connection is formed between the nose 55 and step 51 , which leads to a stable connection between the shoe 3 or shoe body 29 and the frame 31 and the chassis attached to it 7 arises.

From the illustration it can be seen that the maximum width of the mounting tooth 53 is narrower than the minimum width of the recess 40 , which allows that when there is no bias voltage by means of biasing means 15 or by overcoming the biasing force, mounting tooth 53 to the rear, ie in the heel area can be pulled and can then be easily removed from the recess 49 . The part of the stage which is white towards the running gear is preferably not at right angles, but rather is provided with an obtuse angle, which facilitates the sliding together of the correspondingly designed nose 55 into the stage 51 .

FIG. 5 shows a plan view of a section through the fixing element in the toe region 13 in the plane AA ′ of FIG. 4. The almost round cross section of the front fastening tooth 53 can be seen, the curvature of which corresponds to the curvature of the recess 49 in the area of the abutment when shoe 29 is inserted into the binding system. At this point, the front fastening tooth 53 is flattened on the contact surface resting on the frame 31 or the recess 49 and its cross section is not completely circular.

FIG. 6 shows a plan view of a section through the fixing element in the toe region 13 in the plane BB ′ of FIG. 4. The cross section of the fastening tooth 53 is almost circular at the lower end, ie on the side facing the chassis, and has almost the same radius of curvature as the recess 49 .

FIG. 7 finally shows a plan view of a section through the fixing element in the toe region 13 in the plane CC ′ of FIG. 4. Recess 49 has the same radius of curvature as fastening tooth 53 over the greater part of arc length 57 , which is at least partially in contact with front fastening tooth 53 . Le diglich in the edge regions, the radius of curvature of recess 49 is increased. The width W of the opening 59 of the recess 49 is less than the diameter of the front fastening tooth 53 , which leads to the fact that, when the contact pressure is eliminated by the pretensioning means 15 in the fixing element for the heel region 11 , the shoe body 29 with the fastening tooth 53 in the direction of the Heels shifted relative to the recess 49 who can, nose 55 with step 51 is thus no longer engaged and the shoe body 29 can be lifted up from the frame 31 carrying the chassis. A lateral sliding out of the front mounting tooth 53 at the recess 49 is therefore not possible, so that in this way he has the necessary stability against lateral tilting. Alternatively, however, it is also possible in one embodiment that the tooth can be removed from the recess both upwards and laterally.

The open in the above description, in the drawings and in the claims Beard features of the invention can be used individually or in any combination essential for the implementation of the invention in its various embodiments his.
