In den Zeichnungen ist eine erfindungsgemäß gestaltete Kufe dargestellt , welche mit der Kufenhalter-Sohlenplatte 4 und der Kufenhalter-Fersenplatte 5 an einem nicht dargestellten Schuh befestigbar ist .In the drawings, an inventively designed skid is shown, which is fastened to the skid holder sole plate 4 and the blade holder heel plate 5 on a shoe, not shown.
Die Kufe weist symmetrisch zur Mittellinie einen V-förmig aus- gebildeten Wechselmesser-Halter 14 auf, der aus Kunststoff o- der einem anderen spritzfähigen Material besteht . Am Wechselmesserhalter 14 ist das als Kompositbauteil ausgebildete Wechselmesser 1 befestigt . Es weist, wie in DE 42 33 880 Cl im Einzelnen erläutert, einen aus Kunststoff oder dergleichen Ma- terial bestehenden Träger Ia auf, in dessen Unterseite die aus Stahl bestehende Laufschiene Ib eingebettet ist . Das Wechselmesser 1 weist im vorderen und hinteren Bereich beidseitig Rastlöcher 17 auf, in welche in den Wechselmesserhalter integrierte, beidseitig angeordnete Rast-Clip-Drücker 2 einrasten.The runner has symmetrically to the center line on a V-shaped formed change blade holder 14, which consists of plastic or another sprayable material. At the changer blade holder 14 designed as a composite component exchange knife 1 is attached. It has, as explained in DE 42 33 880 Cl in detail, a material consisting of plastic or the like material carrier Ia, in the underside of which the existing running rail Ib is embedded. The change-over blade 1 has in the front and rear areas on both sides detent holes 17, in which engage in the change blade holder, arranged on both sides detent clip pushers 2 engage.
Um eine spielfreie Verrastung des Wechselmessers 1 am Wechsel- messerhalter 14 mit den j eweiligen Rast-Clip-Drückern 2 zu gewährleisten, ist das Wechselmesser 1 im Bereich seiner Rastlöcher 17 gegen die Halterinnenseite vorgespannt , wie mit der gestrichelten Linie 13 in Figur 3 angedeutet ist .In order to ensure a backlash-free locking of the change-over knife 1 on the change-knife holder 14 with the j eweiligen locking clip pushers 2, the change blade 1 is biased in the region of its locking holes 17 against the holder inside, as indicated by the dashed line 13 in Figure 3 ,
Zur Befestigung des Wechselmessers 1 am Wechselmesser-Halter 14 werden zunächst die im hinteren Bereich befindlichen Rast- Clip-Drücker 2 in die entsprechenden Rastlöcher 17 eingeras- tet , worauf das Wechselmesser in Figur 1 im Uhrzeigersinn gegen den vorderen Bereich des Wechselmesser-Halters 14 verschwenkt wird und das Wechselmesser 1 über die hintere Vorspannungslinie 10 sowie die vordere Vorspannungslinie 9 soweit nach oben gedrückt wird, bis die im vorderen Bereich befindli- che und beidseitig am Wechselmesser-Halter 14 vorgesehenenTo fix the change-over knife 1 on the change blade holder 14, the locking clip pushers 2 located in the rear area are first latched into the corresponding latching holes 17, whereupon the change blade in FIG. 1 pivots clockwise against the front area of the change blade holder 14 is pressed and the change blade 1 on the rear bias line 10 and the front bias line 9 so far up to the befindli in the front and on both sides of the change blade holder 14 provided
Rast-Clip-Drücker 2 in die entsprechenden Rastlöcher 17 einrasten.Engage detent clip pusher 2 in the corresponding detent holes 17.
Im ausgerasteten Zustand ist das Wechselmesser 1 vorgespannt , so dass es im vorderen und hinteren Bereich entsprechend den beiden Vorspannungslinien 9 und 10 eine Gegenkrüπunung aufweist . Nach dem Einrasten der Rast-Clip-Drücker 2 in die vorderen und hinteren Rastlöcher 17 wird das Wechselmesser 1 mit der in den Wechselmesserhalter 14 integrierten Form- und Sta- bilisierungsleiste 16, welche Querkräfte aufnimmt und derIn the disengaged state, the change blade 1 is biased so that it has a Gegenkrüπunung in the front and rear area corresponding to the two bias lines 9 and 10. After the latching clip pusher 2 engages in the front and rear latching holes 17, the change-over blade 1 is integrated with the forming and stabilizing strip 16, which absorbs transverse forces and which is integrated into the change blade holder 14
Zentrierung dient, in seiner endgültigen Position am Wechselmesser-Halter 14 kraftschlüssig fixiert . Die die Vorspannung bewirkende Gegenkrüinmung des Wechselmessers 1 hat zur Folge, dass über die gesamte Länge des Wechselmessers 1 , insbesondere im Bereich der vorderen und hinteren Rast-Clip-Drücker 2 , eine konstante, vertikal gerichtete Span- nung aufrechterhalten wird, durch welche ein spielfreier und kraftschlüssiger Sitz des Wechselmessers 1 am Wechselmesser- Halter 14 gewährleistet ist .Centering is fixed in its final position on the change blade holder 14 frictionally. The result of the bias causing Gegenkrüinmung the change-over knife 1 has the consequence that over the entire length of the change-over blade 1, in particular in the region of the front and rear locking clip pushers 2, a constant, vertically directed voltage is maintained tion, by which a backlash and non-positive fit of the change-over blade 1 is ensured at the change blade holder 14.
Der Wechselmesserhalter 14 weist an seinem unteren Ende eine der Wandstärke der oben gelegenen Zungen des Wechselmessers 1 entsprechende Ausnehmung 8 auf, so dass das Wechselmesser 1 sich bündig an den Wechselmesserhalter 14 anschließt .The change blade holder 14 has at its lower end a the wall thickness of the tongues of the rotary blade 1 located above corresponding recess 8, so that the change blade 1 is flush with the change blade holder 14.
Wie die Zeichnungen erkennen lassen, weist das Wechselmesser 1 im vorderen und hinteren Bereich Schlitze 18 und 19 auf, mit welchen verhindert wird, dass die Außenwandungen des Wechsel- messers 1 beim Aufsetzen auf den Wechselmesser-Halter 14 , also bei Veränderung der Vorspannungslinien 9 und 10, deformiert werden.As can be seen from the drawings, the change-over knife 1 has slots 18 and 19 in the front and rear areas, which prevent the outer walls of the change blade 1 from being placed on the change blade holder 14, ie when the pretension lines 9 and 10, to be deformed.
Zur Abnahme des Wechselmessers 1 sind die vorderen und hinteren Rast-Clip-Drücker 2 gegeneinander und einwärts bis in die mit 15 in Fig. 3 angedeutete Position aus den Rastlöchern 17 zu drücken, worauf das Wechselmesser 1 aufgrund seiner Vor- Spannung in die mit den Vorspannungslinien 9 und 10 in Figur 1 angedeutete Position zurückfedert . Das Wechselmesser 1 kann nun ohne Kraftaufwand vom Wechselmesser-Halter 14 abgenommen werden. Das Einsetzen eines neuen Wechselmessers 1 erfolgt in umgekehrter Reihenfolge .To remove the retractable blade 1, the front and rear locking clip pushers 2 against each other and inwardly to press in the direction indicated by 15 in Fig. 3 position from the locking holes 17, whereupon the change blade 1 due to its pre-tension in the with Preload lines 9 and 10 in Figure 1 indicated position springs back. The change blade 1 can now be removed without effort by the change blade holder 14. The insertion of a new change diameter 1 is done in reverse order.
Die beschriebene Rast-Clip-Technik ist auch bei Verwendung von herkömmlichen Vollstahlmessern geeignet . In diesem Fall ist das Stahlmesser mit Rastlöcher aufweisenden Zungen auszustatten, welche angespritzt , angeklebt oder angeschweißt sind, wobei das Vollstahlmesser anstelle der Formleiste 16 in einen im Wechselmesser-Halter 14 befindlichen Schlitz eingesteckt wird .The locking clip technique described is also suitable when using conventional solid steel knives. In this case, the steel blade is equipped with locking holes having tongues which are molded, glued or welded, the solid steel blade is inserted instead of the mold bar 16 in a slot located in the changer holder 14 slot.
Die spezielle Bauweise des erfindungsgemäßen Wechselmessers 1 gestattet minimale Wandstärken, da die vorn und hinten beidseitig vorgesehenen, dünnwandigen, flexiblen Zungen, in wel- chen sich die Rastlöcher 17 befinden, für ausreichende Steifigkeit der Wand sorgen. Diese Zungen sind derart vorgespannt, dass sie vor Aufschieben des Wechselmessers auf den Wechsel- messerhalter 14 , also im nicht aufgespreizten Zustand, die mit 13 angedeutete Position einnehmen. Diese Vorspannung gewähr- leistet zusammen mit optimaler Konturanpassung der Rast-Clip- Drücker 2 und der Rastlöcher 17 einen spielfreien Sitz .The special design of the rotary knife 1 according to the invention allows minimum wall thicknesses, since the front and rear provided on both sides, thin-walled, flexible tongues, in which the locking holes 17 are provided for sufficient rigidity of the wall. These tongues are biased in such a way that they assume the position indicated by 13 before pushing the changing blade onto the changing blade holder 14, that is to say in the unexpanded state. This bias ensures together with optimal contour adjustment of the locking clip pushers 2 and the locking holes 17 a backlash-free seat.
Für die erforderliche Stabilität des extrem dünnwandigen und damit leichten Wechselmessers 1 sorgt die in den Wechselmes- ser-Halter 14 integrierte Form- und Stabilisierungsleiste 16 , welche tief in den im Wechselmesser 1 vorgesehenen Schlitz eingebettet ist .For the required stability of the extremely thin-walled and thus easy change blade 1, the integrated into the change-state holder 14 shape and stabilizing bar 16 which is deeply embedded in the slot provided in the change blade 1 slot.
Diese Wechselmessergestaltung ermöglicht einen problemlosen, einfachen und extrem schnellen Austausch des Wechselmessers ohne mechanische Hilfsmittel .This change blade design allows a trouble-free, simple and extremely fast replacement of the change-over blade without mechanical aids.
Die spezielle V-förmige Kontur in Verbindung mit der in dem Wechselmesser-Halter 14 integrierten Form- und Stabilisie- rungsleiste 16 gewährleistet bei vergleichsweise geringem Gewicht eine äußerst wirksame und belastbare Verbindung zwischen Wechselmesser 1 und Wechselmesser-Halter 14. Die mit den Rastlöchern 17 zusammenwirkenden Rast-Clip-Drücker 2, die im vor- deren und hinteren Bereich angeordnet sind, ermöglichen bei Anwendung geringer Kraft einen schnellen Austausch abgenutzter Messer gegen neue Messer in weniger als zehn Sekunden. Auch ist die Herstellung eines Systems mit diesem Kompositmesser problemlos und kostengünstig .The special V-shaped contour in conjunction with the integrated in the change blade holder 14 form and stabilizing bar 16 ensures at comparatively low weight an extremely effective and resilient connection between the change diameter 1 and change blade holder 14. The cooperating with the locking holes 17 Latch clip pushers 2, which are their rear and rear area, allow for low force application a quick replacement of worn knives against new knife in less than ten seconds. Also, making a system with this composite knife is easy and inexpensive.
Zeitaufwändiges Kufenschleifen und kostenintensive Wartungsund Instandhaltungsarbeiten, die nur durch teure Fachkräfte bei Verwendung teurer Schleifmaschinen ausgeführt werden kön- nen, entfallen .Time-consuming skid-grinding and cost-intensive maintenance and repair work, which can only be carried out by expensive specialists using expensive grinding machines, are eliminated.
Ein von einer Fachkraft in herkömmlicher Weise mit relativ teuren Schleifmaschinen durchgeführter Kufenschliff benötigt bei normaler Kantenabnutzung etwa die 15-fache Arbeitszeit bei schlechterer Qualität der Kufenkanten. ,A runner grinding performed by a specialist in a conventional manner with relatively expensive grinding machines requires about 15 times the working time with poorer quality of the runner edges with normal edge wear. .
Wie die Figuren 1 , 2 und 6 deutlich machen, sind die Kufenhalter-Sohlenplatte 4 und die Kufenhalter-Fersenplatte 5 über diagonal und schräg zueinander verlaufende, sich kreuzende Tor- sions- und Biegestäbe 3a und 3b mit dem Wechselmesser-Halter 14 im hinteren bzw. dessen vorderen Bereich verbunden. Wie ferner erkennbar ist , verbinden die Torsions- und Biegestäbe 3a, 3b unter Bildung eines Torsionsdoppelkreuzes 3 den Randbereich der Kufenhalter-Sohlenplatte 4 bzw. der Kufenhalter- Fersenplatte 5 mit dem j eweils gegenüberliegenden Randbereich des Wechselmesser-Halters 14. Dieses Torsionsdoppelkreuz 3 dient der Reduzierung der im Wechselmesser 1 und dem Wechsel- messer-Halter 14 bei Gebrauch entstehenden Torsions- und Biegekräfte . Hierdurch werden die durch laufdynamische Einwirkung entstehenden Torsions- und Biegekräfte zwischen der Kufenhalter-Sohlenplatte 4 bzw. der Kufenhalter-Fersenplatte 5 und dem das Wechselmesser 1 tragenden Wechselmesser-Halter 14 aufgefangen und weitgehend neutralisiert . Beim innenseitigen Querbelasten des vorderen Bereichs des Wechselmessers 1 werden die entstehenden Torsions- und Biegekräfte zwischen dem vorderen, innenseitig liegenden Rastloch 17 über den eingerasteten Rast-Clip-Drücker 2 und die innenseitige Halter-Sohlenplatte 4 sowie über die im Wechselmesserhalter 14 linear verlaufende Form- und Stabilisierungsleiste 16 diagonal über das Torsions-Doppelkreuz 3 auf das im Fersenbereich außenseitig liegende Rastloch 17 mit dem eingerasteten Rast-Clip-Drücker 2 sowie die außenseitige Fersenplatte 5 ü- bertragen.As FIGS. 1, 2 and 6 make it clear, the blade holder sole plate 4 and the runner holder heel plate 5 are arranged on diagonally and obliquely extending, intersecting torsion and bending bars 3a and 3b with the change blade holder 14 in the rear or rear its front area connected. As can also be seen, connect the torsion and bending rods 3a, 3b to form a Torsionsdoppelkreuzes 3, the edge region of the blade holder sole plate 4 and the runner bracket heel plate 5 with the each opposite edge region of the change blade holder 14. This Torsionsdoppelkreuz 3 serves the Reduction of the torsion and bending forces generated in the change-over blade 1 and the changer holder 14 during use. As a result, the resulting torsional and bending forces between the blade holder sole plate 4 and the blade holder-heel plate 5 and the change blade 1 bearing change blade holder 14 are collected and largely neutralized. When inside transverse loads of the front portion of the rotary blade 1, the resulting torsional and bending forces between the front, inside latching hole 17 on the latched locking clip pushers 2 and the inside holder-sole plate 4 and on the change blade holder 14 linearly extending mold and stabilizing bar 16 diagonally over the torsion doorbell 3 on the outside in the heel area latching hole 17 with the latched detent clip pusher 2 and the outside heel plate 5 ü transferred.
Nach dem gleichen Prinzip werden bei innenseitigem Querbelasten die im innenseitigen Fersenbereich entstehenden Quer- und Biegekräfte diagonal über das Torsions-Doppelkreuz 3 auf den außenseitigen Kufenfrontbereich übertragen .According to the same principle, the transverse and bending forces arising in the inside heel area are transferred diagonally via the torsion doubler 3 to the outside skid front area in the case of the inside lateral load.
Somit werden die beim Beschleunigen an der Innenseite der Kufenhalter-Sohlenplatte 4 entstehenden Quer- und Vertikalkräfte über das Torsions-Doppelkreuz 3 diagonal auf die Außenseite der Kufenhalter-Fersenplatte 5 übertragen . In umgekehrter Weise werden z . B . beim Durchfahren extrem enger Kurven die vorgenannten Kräfte von der Außenseite der Kufenhalter- Fersenplatte 5 wiederum diagonal über das Torsions-Doppelkreuz 3 auf die Innenseite der Kufenhalter-Sohlenplatte 4 übertragen.Thus, the transverse and vertical forces generated during acceleration on the inside of the blade holder sole plate 4 are transmitted diagonally to the outside of the blade holder heel plate 5 via the torsion doubler 3. In the reverse manner z. B. when driving through extremely tight curves, the abovementioned forces from the outside of the blade holder heel plate 5 in turn diagonally transmitted via the torsion doublet 3 on the inside of the blade holder sole plate 4.
Zwischen Torsionsdoppelkreuz 3 und dem Wechselmesser-Halter 14 sind Durchbrüche 7 ausgebildet, welche ohne Verlust der Stabi- lität zu einer Gewichtsminderung führen .Breakthroughs 7 are formed between the torsion double cross 3 and the exchangeable knife holder 14, which lead to a reduction in weight without loss of stability.
Eine weitere Verbesserung der Stabilität und damit eine verbesserte Aufnahme von Torsions- und Biegekräften bewirkt die in Figur 2 erkennbare Gestaltung der Kufenhalter-Sohlenplatte bzw . Fersenplatte 4 und 5.A further improvement in stability and thus improved absorption of torsional and bending forces causes the recognizable in Figure 2 design of the blade holder sole plate or. Heel plate 4 and 5.
Diese Platten bestehen jeweils aus einem in sich geschlossenen Ring 4a und 5a, in welchem zur Bildung eines Torsionskreuzes 11 bzw. 12 diagonal verlaufende, sich im Mittelpunkt kreuzende Speichen IIa, IIb bzw. 12a, 12b vorgesehen sind .These plates each consist of a self-contained ring 4a and 5a, in which are provided to form a torsion cross 11 and 12 diagonally extending, in the center crossing spokes IIa, IIb and 12a, 12b.
Auch vertikal auf das Wechselmesser 1 wirkende Kräfte werden von den Torsions- und Biegestäben 3a, 3b des Torsions- Doppelkreuzes 3 aufgenommen und weitestgehend neutralisiert .Also acting vertically on the change blade 1 forces are absorbed by the torsion and bending rods 3a, 3b of the torsion doubler 3 and largely neutralized.
Die erfindungsgemäße Gestaltung des aus Wechselmesser-Halter 14 , Kufenhalter-Sohlen- und Fersenplatten 4 und 5 und Torsi- ons-Doppelkreuz 3 bestehenden Grundkörpers ermöglichen eine extrem leichte, filigrane und materialsparende Konstruktion bei überdurchschnittlicher Torsions- und Biegesteifigkeit des Wechselmesserhalters 14.The design according to the invention of the base body consisting of change blade holder 14, blade holder sole and heel plates 4 and 5 and torsion double cross 3 enables an extremely lightweight, filigree and material-saving construction with above-average torsional and bending stiffness of the change blade holder 14.
Das Torsions-Doppelkreuz 3 des Wechselmesser-Halters 14 gewährleistet zusammen mit einem angenieteten, verschraubten, angeklebten oder angespritzten Schuh einen geradlinigen Verlauf des Wechselmessers 1 , das auch bei hohen Querbelastungen seine Form nicht verliert .The torsion-double cross 3 of the change blade holder 14, together with a riveted, screwed, glued or molded shoe ensures a straight course of the change blade 1, which does not lose its shape even at high lateral loads.
Diese Konstruktion mit dem Torsions-Doppelkreuz und der Längsrichtung verlaufenden Form- und Stabilisierungsleiste gewährleisten insbesondere in der Beschleunigungsphase eine überdurchschnittliche Verwindungs- und Biegesteifigkeit des Kufen- Systems .This construction with the torsion dou- ble-cross and the longitudinal direction of the forming and stabilizing strip ensure an above-average torsional and bending stiffness of the runner system, especially in the acceleration phase.
Wegen der durch das Torsions-Doppelkreuz erzielten Verwindungs- und Biegesteifigkeit können Wechselmesser-Halter 14 mit vergleichsweise geringen Wandstärken verwendet werden, was zum einen zur Gewichtsreduzierung und zum anderen zur Herabsetzung der Herstellkosten und damit der Verkaufspreise führt .Because of the twisting and bending stiffness achieved by the torsion doubler, change-blade holders 14 can be used with comparatively low wall thicknesses are used, which leads to a weight reduction and on the other hand to reduce the production costs and thus the sales prices.
Zur Schonung der Lauffläche und insbesondere der Kanten derTo protect the tread and especially the edges of the
Laufschiene Ib und, um sicheres Gehen außerhalb von Eisflächen zu ermöglichen, kann, wie mit den Figuren 3 und 6 veranschaulicht , auf den Wechselmesser-Halter 14 ein das Wechselmesser 1 vollständig überdeckender Kufenschoner 20 aufgesetzt werden . Er weist an seinem vorderen und hinteren Ende gegeneinander gerichtete Zapfen 21 und 22 auf, welche in die Durchbrüche 2a der ringförmig gestalteten und in die Rastlöcher 17 eingreifenden Rast-Clip-Drücker 2 einrasten . Den Rastzapfen 21 und 22 sind am oberen Rand des Kufenschoners 20 vorgesehene Entriege- lungszungen 23 zugeordnet , mit welchen die Zapfen 21 und 22 gegen die Federwirkung des aus elastischem Material bestehenden Kufenschoners 20 nach außen gedrückt werden können, bis die Zapfen 21 bzw. 22 aus den Ausnehmungen 2a ausrasten, worauf der Kufenschoner 20 abgenommen werden kann. Die Seitenwän- de des im Querschnitt U-förmig gestalteten Kufenschoners 20 sind mit über die Länge verteilten Schlitzen 24 ausgestattet , wodurch die Flexibilität des Kufeschoners 20 erhöht und dieser konturgenau an den Wechselmesser-Halter 14 mit dem Wechselmesser 1 angepasst und mit diesem verrastet werden kann .Running rail Ib and, to allow safe walking outside of ice surfaces, can, as illustrated with Figures 3 and 6, on the change blade holder 14, a change blade 1 completely overlapping Kufenschoner 20 are placed. He has at its front and rear end against each other directed pins 21 and 22, which engage in the openings 2a of the annular shaped and engaging in the locking holes 17 locking clip pushers 2. The latching pins 21 and 22 are assigned to the upper edge of the skid shoe 20 unlocking lungs tongues 23, with which the pins 21 and 22 can be pressed against the spring action of the elastic material Kufenschoners 20 to the outside until the pin 21 or 22 from disengage the recesses 2a, after which the skid protector 20 can be removed. The side walls of the cross-sectionally U-shaped runner protector 20 are provided with slits 24 distributed over the length, which increases the flexibility of the skiff protector 20 and allows it to be adapted precisely to the change blade holder 14 with the exchangeable blade 1 and latched thereto ,
Bei dieser exakten Passform kann der Kufenschoner 20 aus einem leichten, extrem flexiblen und trittsicheren Material , vorzugsweise Kunststoff , bestehen .In this exact fit, the skid shoe 20 may consist of a lightweight, extremely flexible and sure-footed material, preferably plastic.
Der Wechselmesser-Halter 14 ist so gestaltet , dass in seinem Front- bzw. Heckbereich wahlweise ein Clip 6 mit einem Leuchtmittel oder einem Sender zur Funkübertragung der die Nutzung identifizierenden Daten angeordnet , vorzugsweise eingerastet, werden kann .The change-diameter holder 14 is designed so that in his front or rear area optionally a clip 6 with a light source or a transmitter for radio transmission of the use identifying data arranged, preferably locked, can be.
Als Leuchtmittel ist insbesondere eine Licht emittierende Dio- de, eine sogenannte LED, geeignet , welche gewünschtenfalls mehrfarbig blinkendes Licht abgeben kann.As light-emitting means, in particular, a light-emitting diode, a so-called LED, is suitable, which if desired can emit multicolored flashing light.
Dieses Leuchtmittel kann von einem Bewegungsschalter z . B . durch die Erschütterungen beim Schlittschuhlaufen in Betrieb gesetzt werden und von einem Verzögerungsausschalter in Ruhelage des Sportgerätes nach einer geraumen Zeit selbstständig wieder ausgeschaltet werden .This light source can by a motion switch z. B. be set by the vibrations when skating in operation and switched off automatically by a delay switch in rest position of the sports equipment after a limited time again.
Soweit erfindungsgemäß gestaltete Schlittschuhe im gewerbli- chen Betrieb, also im Schlittschuhverleih, eingesetzt werden, kann anstelle des Leuchtmittels oder zusätzlich zu diesem auch ein Sender vorgesehen sein, mit welchem die Nutzerdaten, also im Wesentlichen die Daten zur Identifizierung des Schlittschuhs und zur Erfassung der Betriebs- und Kostendaten, über- tragen werden. Insofar as skates designed according to the invention are used in commercial operation, ie in skate rental, instead of the illuminant or in addition to it, a transmitter can also be provided, with which the user data, ie essentially the data for identifying the skate and detecting the operation - and cost data to be transferred.
