(54) SPIDOGRAF NA MERANIE DOBY OPORY(54) SPIDOGRAPH FOR MEASURING THE SUPPORT TIME

Vynález sa týká spidografu, ktorý umožňuje súčasné meranie rychlosti športovca a doby opory pri behoch a skokoch.The invention relates to a spidograph which allows simultaneous measurement of the speed of an athlete and the support period during runs and jumps.

U doteraz známých konátrukcií spidografov bolo možné merat len rýchlost Sportovce ako funkclu času. Existujú zariadenia, ktoré umožňujú meranie doby opory. Pod pojmom doby opory sa rozumie časový interval, počas ktorého sa dotýká podrážka obuvi podložky, ktorou može byt bežecká dráha alebo odraziáte. Doba opory sa može merat bud nepriamo, napr. vyhodnocováním kinematografických záznamov, alebo priarno, meraním časového intervalu, ktorý je vymedzený elektrickými impulzami. V doteraz známých zariadeniach meraný subjekt tahal lanko, volné položené na zemi. Pohyb lanka sa pri takomto usporiadaní nedal využit na meranie rýchlosti. Je samozřejmé, že ak aa pri meraní získá komplexnějšia informácia, je možné presnejšie analyzovat akúmaný jav, čo doterajáie zariadenia neumožňovali.For the known constructions of spidographs, only the Athlete's speed could be measured as a function of time. There are devices that allow to measure the support time. The support period is the time interval during which the sole of the shoe touches the mat, which may be a running track or a bounce. The support time can be measured either indirectly, e.g. evaluating cinematographic recordings, or prism, by measuring a time interval defined by electrical pulses. In previously known devices, the subject to be measured pulled a cord loose laid on the ground. With such an arrangement, the movement of the cable could not be used for speed measurement. It goes without saying that if aa obtains more complex information during the measurement, it is possible to analyze more precisely the phenomenon which was not possible by the previous devices.

Uvedené nedostatky odstraňuje spidograf pře meranie doby opory pódia vynálezu, ktorého podstata spočívá v tom, že vodivé lanko, ktoré je zapojené do vyhodnocovacieho zariadenia, a cez cievku, je vedené jedným závitom okolo měrného kotúča spidografu, je druhým koncom připevněné ne meraný subjekt, pričom kontakt podoávy meraného subjektu je cez zem připojený na druhý kontakt vyhodnocovacieho zariadenia, ktorý je spojený so zemou.The above-mentioned drawbacks are eliminated by the spidograph measuring the support period according to the invention, which consists in that the conductive cable which is connected to the evaluation device and is guided through the coil through one thread around the measuring wheel of the spidograph. the contact of the metered subject is connected across the ground to a second contact of the evaluation device, which is connected to the ground.

Pokrok spidografu, umožňujúceho meranie doby opory pódia vynálezu spočívá predovšetkýmThe progress of the spidograph to measure the support period of the invention lies above all

200 070 v tom, že týmto zariadením je možné spracoval vo vyhodnocovacom zariadení cyklické preruáovanie elektrického obvodu pri běhu do grafického záznamu s vyznačením opornej fázy a letověj fázy a z takto získaného záznamu je možné e dostatočnou presnoaíou zisloval, ako aa maní doba opory, doba letověj fázy, ako aj frekvencia kroku, čo je zvlášl doležité najma pri rozbehoch pri skokoch. Súčaane z pohybu lanka je možné vyhodnotil v apidografe rýchlosl měřeného subjektu.200 070 in that it is possible to process cyclic interruption of the electric circuit while running into a graphical record indicating the support phase and the flight phase in this evaluation device and from this record it is possible to obtain sufficient accuracy as to the maneuvering time and support phase , as well as the frequency of the step, which is especially important for jump start-ups. At the same time, the velocity of the measured subject can be evaluated in the apidograph.

Na připojenou obrázku je znázorněný epidograf v zapojení podlá vynálezu. Vodivé lanko 2 je zapojené do vyhodnocovacieho zariadenia 1 a cez cievku 2» z ktorej aa odvíja cez čelo je vedené jedným závitom okolo měrného katáča 4 otočné uloženého v ložisku 10. Druhým koncom je vodivé lanko 2 připevněné na meraný subjekt 2» íí® se uzatvára v opornej fáze elektrický obvod cez kontakt 6 podošve a podložkou cez zem 7 na druhý kontakt 9 vyhodnocovacieho zariadenia 1. Na výstup 8 vyhodnocovacieho zariadenia 1 je možné zapojil záznamové zariedenie.The attached figure shows an epidograph in an embodiment according to the invention. The conductive cable 2 is connected to the evaluation device 1 and through a spool 2 from which aa unwinds through the face is guided by one thread around the measuring trolley 4 rotatably mounted in the bearing 10. The other end is the conductive cable 2 in the supporting phase, the electrical circuit via the sole contact 6 and the ground across the ground 7 to the second contact 9 of the evaluation device 1. A recording device can be connected to the output 8 of the evaluation device 1.

Zariadenie znázorněné na obrázku podle vynálezu pracuje následovně: meraný subjekt 2 bežec, skokan je časlou elektrického obvodu vytvořeného vyhodnocovacím zariadením 1, vodivým lankom 2, ktoré meraný subjekt 2 za sebou lahá, kontaktem 6 medzi podrážkou e podložkou v opornej fáze pohybu, teda žernou 7 spát do vyhodnocovacieho zariadenia 1. V letovej fáze, tj. keS sa meraný subjekt 2 nedotýká podložky, sa obvod rozchodí a jeho odpor sa zvačáí o niekoíko rádov. Takáto velká změnu odporu je možné bez problémov spracoval vo vyhodnocovacom zariadení 1 na požadovaná ároveň. Kedže pri běhu dochádza k cyklickému preruáovaniu elektrického obvodu, je výhodné používal grafický záznam, na ktorom je oporná fáza zaznačená eignáloa s árovňou, napr. 1 a letová fáza signálom s árovňou 0. Meraný subjekt 2 P11· běhu lahá vodivé lanko 2, ktoré otáča měrný kotáč spidografu 4, čím je vyhodnotená rýchlosl pohybu. Pri letovej fáze sa rozpojí kontakt 6, čím sa preruší elektrický okruh, tvořený vodivým lankom 2, měřeným subjektom 5» žernou 7 a vyhodnocovacím zariadením 1. Preruáenie obvodu je spracované vyhodnocovacím zariadením 1 a na jeho výstupe 8 je elektrický signál s požadovanou árovňou.The device shown in the figure according to the invention operates as follows: the measured subject 2 runner, the jumper is a part of the electrical circuit formed by the evaluating device 1, the conductive cable 2, which the measured subject 2 lies in succession, contact 6 between the sole e sleep in the evaluation device 1. If the subject 2 does not touch the substrate, the circuit is treaded and its resistance is increased by several orders of magnitude. Such a large change in resistance can be processed without problems in the evaluation device 1 to the desired level. Since the electrical circuit is cyclically interrupted during operation, it is advantageous to use a graphical record on which the supporting phase is marked with an electrical arena, e.g. 1 and the flight phase by the signal with the echarion 0. The measured subject 2 P 11 · is running a conductive cable 2, which rotates the measuring disc of the spidograph 4, thus evaluating the speed of movement. In the flight phase, the contact 6 opens, thereby interrupting the electrical circuit formed by the conductive cable 2, measured by the subject 5 and the evaluation device 1. The circuit break is processed by the evaluation device 1 and at its output 8 is an electrical signal with the desired power line.
