Katteensiirtomekanismi - Transmissionsmekanism for betåck-ning 5Margin Transfer Mechanism - Transmissionsmekanism for betåck-Ning 5

Keksinto koskee katteensiirtomekanismia katetussa rautatie-vaunussa, jossa on toisiinsa ja/tai vaunurunkoon sulkuasen-nossa liittyviå kateosia, joista ainakin yksi on siirtome-kanismilla siirrettåvisså sulkuasennosta liikutusasentoon ja 10 takaisin, jossa liikutusasennossa kateosa on liikutettavissa juoksukiskoja pitkin vaunun pituussuunnassa sulkuasennossa olevan kateosan påållitse, tåmån siirtomekanismin kåsittåes-så ainakin yhden kåyttovålineen, joka kåyttdakselin ja sii-hen kytketyn muuntomekanismin kautta kåyttåå kåyttdtankoj en 15 sekå vipujen tai vastaavien vålityksellå ainakin yhtå vaunun kummallekin puolelle jårjestettyå kååntoakselia kateosan mainittua siirrettåvyyttå vårten.The invention relates to a roof transfer mechanism in a covered railway carriage having roof sections connected to each other and / or to the carriage body in the closed position, at least one of which can be moved by the transfer mechanism from the closed position to the moving position and back the transmission mechanism comprising at least one drive means which, via the drive axle and the conversion mechanism connected thereto, drives the drive rods 15 and at least one drive provided on each side of the carriage via levers or the like.

Siirtokatevaunun katteensiirtomekanismeja on kuvattu esimer-20 kiksi kuulutusjulkaisussa FI-87332. Tåsså yleisesti kåytosså olevassa rakennetyypisså kateosia siirretåån liikutusasentoon eli levitysasentoon ja siitå pois kateosien sulkuasen-toon vaunun påådyisså olevilla kåsipydrillå, joiden liike vålitetåån ketjupyorien, murrosnivelien ja akselien avulla 25 vaunun keskikohtaan sijoitettuun vaihteistoon. Vaihteistosta * liike vålittyy itse kateosaa nostaviin ja siirtåviin vipui- hin ja tankoihin kuten esimerkiksi patenttihakemuksen FI-913228 mukaisiin kååntoakseleihin. Tållå vaunun påådyistå sen keskikohdan kautta vaunun sivuilla oleviin katteen kåån-30 tomekanismeihin vievållå rakenteella on epåkohtana erittåin pitkåt liikkeen siirtomatkat kåsipySråstå vaihteeseen, mistå ‘ seuraa kaliis ja toimintahåirioille altis rakenne, johon johtaa my6s rakenteen monimutkaisuus useine nivelineen. Kai-kissa vaunutyypeisså ei lisåksi pååtyovien ja muiden raken-35 teiden vuoksi ole rautatievaunun påådyisså kunnollista tilaa kåsipyorille tai vastaaville kåyttolaitteille.The roof transfer mechanisms of the transfer roof wagon are described, for example, in publication FI-87332. In this type of construction in common use, the roof parts are moved to the movement position, i.e. the spreading position, and out of the roof parts to the closed position by means of hand-held handrails at the ends of the carriage. From the gearbox *, the movement is transmitted to the levers and rods raising and moving the roof part themselves, such as the pivot shafts according to patent application FI-913228. Here, the structure leading from the ends of the wagon through its center to the roof mechanisms of the roof on the sides of the wagon has the disadvantage of very long displacements of movement from the handrail to the gearbox, resulting in In addition, due to the end doors and other structures, there is no proper space at the ends of the railway carriage for handwheels or similar drives on all types of wagons.

92665 2 Tåstå sijoitusperiaatteesta oleellisesti poikkeavia raken-teita ei ole kåytosså. Esimerkiksi julkaisuissa SE-419 071 ja US-3 513 783 on tosin esitetty rautatievaunun ovien luki-tusmekanismit, joissa kåyttdlaite on itse ovissa, mutta nåi-5 tå ei voida millåån tavoin soveltaa siirtokatteen siirtome-kanismin kåyttodn, koska siirtomekanismi on vaunun runkoon kuuluva osa, jota ei voida kåyttåå siitå irrallisessa siir-tokatteessa olevalla laitteella.92665 2 There are no structures in use that differ materially from this investment principle. For example, although SE-419 071 and U.S. Pat. No. 3,513,783 disclose locking mechanisms for railway car doors in which the operating device is in the doors themselves, this cannot in any way be applied to the use of the transfer cover transmission mechanism, since the transmission mechanism is part of the car body. , which cannot be used with a device with a separate transfer cover.

10 Keksinnon tavoitteena on siten aikaansaada katteensiirtome-kanismi, jossa olisi huomattavasti lyhyemmåt siirtoliikkeen vålitysmatkat kuin tunnetuissa laitteissa. Keksinnon toisena tavoitteena on tållainen siirtomekanismi, jossa on våhån niveliå ja hammaspyåriå tai vastaavia, ja siten yksinkertai-15 sen ja toimintavarman rakenteen mahdollistaminen. Keksinndn kolmantena tavoitteena on se, ettå mahdolliset toiminnalli-set kone-elimet voidaan integroida kåyttoakseleihin tai -tankoihin ja varsinkin ilman våliniveliå tai vastaavia kes-tåvån rakenteen saamiseksi. Keksinnån neljåntenå tavoitteena 20 on tållainen siirtomekanismi, jossa kåyttolaite on sellai-sessa kohdassa tai asennossa ettå se on kåytettåvisså myos tavaravaunun ollessa lastauslaiturin kohdalla, jolloin luok-sepååståvyys vaunun alaosaan on rajoitettu. Lisåksi keksinnon tavoitteena on tållainen rakenne, joka mahdollistaa hin-25 naltaan edullisen siirtomekanismin erityyppisellå siirtokat-teella varustettuihin rautatievaunuihin.It is therefore an object of the invention to provide a margin transfer mechanism which has considerably shorter transfer travel distances than in known devices. Another object of the invention is to provide such a transfer mechanism with few joints and gears or the like, and thus to enable a simple and reliable structure. A third object of the invention is that any functional machine elements can be integrated into the drive shafts or rods and in particular without intermediate joints or the like in order to obtain a durable structure. A fourth object of the invention is to provide such a transfer mechanism in which the drive device is in such a position or position that it can be used even when the freight wagon is at the loading dock, whereby the access to the lower part of the wagon is limited. In addition, it is an object of the invention to provide such a structure which enables a low-cost transmission mechanism for railway carriages with different types of transfer covers.

Edellå kuvatut haittapuolet saadaan eliminoitua ja edellå-mainitut tavoitteet saavutetaan keksinn6n mukaisella kat-30 teensiirtomekanismilla, jolle on tunnusomaista se, mitå on mååritelty patenttivaatimuksen 1 tunnusmerkkiosassa.The disadvantages described above can be eliminated and the above-mentioned objects are achieved by the roof transfer mechanism according to the invention, which is characterized by what is defined in the characterizing part of claim 1.

Keksinndn tårkeimpånå etuna on se, ettå kyseinen katteen-siirtomekanismi muodostuu suhteellisen lyhyistå akseleista 35 ja tangoista, jotka ovat sijoitettavissa tiiviiseen tilaan, jolloin våltetåån pitkåt voimansiirtomatkat. Keksinnon toisena etuna on se, ettå voimaa siirtåvåt kone-elimet, kuten hammaspyoråt tai ruuvit, ovat rakenteeltaan yksinkertaisia, 92665 3 niitå on våhån ja ettå varsinkin pyorivien akseleiden pien-ten kulmamuutosten edellyttåmiå murrosniveliå ei yleenså ole tarpeen kåyttåå. Keksinnon eråånå etuna on vielå se, ettå se on sovellettavissa kaikentyyppisiin tavaravaunuihin riippu-5 matta siitå, onko niisså påådyt, pååtyovet, keskikonsoli tai ei keskikonsolia tai onko levittyviå siirtokateosia lukumåå-råisesti yksi tai useampia tai minkå tyyppisiå siirtokate-osat ovat.The main advantage of the invention is that the cover transmission mechanism in question consists of relatively short shafts 35 and rods which can be placed in a tight space, thus avoiding long transmission distances. Another advantage of the invention is that the power-transmitting machine members, such as gears or screws, are simple in construction, 92665 3 are few in number and that it is generally not necessary to use the articulated joints required for small angular changes in the rotating shafts in particular. Another advantage of the invention is that it is applicable to all types of freight wagons, regardless of whether they have ends, end doors, a center console or not a center console, or whether there are one or more or more types of transferable coverings.

Kuviossa 1 on esitetty yleisesti keskikonsolilla 24 varus-tettu rautatievaunu 1, joka voi olla esimerkiksi patenttiha-kemuksessa FI-921928 kuvattua tyyppiå. Keksinto ei tieten-25 kåån ole rajoitettu kåytettåvåksi vain tåmåntyyppisesså rau-tatievaunussa, vaan sitå voidaan soveltaa minkå tyyppisesså rautatievaunussa tahansa, kuten jåljempånå selostetaan. Rau-tatievaunussa 1 on sinånså tunnettuja toisiinsa ja/tai vau-nun runkoon sulkuasennossa liittyviå kateosia 2, joista ai-30 nakin yksi on siirtomekanismilla 27 siirrettåvisså sulku- asennosta liikutusasentoon ja takaisin. Liikutusasennossaan levitetty kateosa on liikutettavissa kuvioissa ei-esitettyjå juoksukiskoja pitkin vaunun pituussuunnassa L kulloinkin sulkuasennossa olevan kateosan påållitse tai ulkopuolitse.Figure 1 shows a railway carriage 1 generally equipped with a center console 24, which may be of the type described in, for example, patent application FI-921928. Of course, the invention is not limited to use only in this type of railway carriage, but can be applied to any type of railway carriage, as will be described below. The railway carriage 1 has per se known roof parts 2 connected to each other and / or to the carriage body in the closed position, at least one of which is movable by the transfer mechanism 27 from the closed position to the moving position and back. The cover part applied in its movable position can be moved along running rails (not shown in the figures) in the longitudinal direction L of the carriage on or outside the cover part in each case in the closed position.

Katteensiirtomekanismi 27 kåsittåå kutakin siirrettåvåå ka-teosaa kohti tyypillisesti yhden kåyttovålineen 3, kuten kå-sikammen tai vastaavan. Kåyttovåline 3 on keksinnon mukaan edullisesti irrotettava ja/tai rautatievaunun sivun 10 ky-5 seisen rakenteen, kuten keskikonsolin tai sivupalkin, sisåån kåånnettåvå, jotta se ei vaunun kulun aikana lisåå vaunun leveyttå. Tåmå pyoritettåvå kåyttovåline 3 on kuvioiden to-teutusmuodoissa kytkettåvisså akseliin 24 ja siitå ketjuvå-lityksellå 25 tai vastaavalla hihnavålityksellå tai hammas-10 pyåråvålityksellå tai muulla sopivalla tavalla kåyttoakse-liin 5, joka on keksinnon mukaan poikittain ja yleenså koh-tisuorassa vaunun pituussuuntaa L vastaan. Tållå matkan H nostavalla vålityksellå kåyttovåline 3 on riittåvåsti tava-ravaunun sivupalkin 12 ylåpuolella, jolloin sitå voidaan 15 pyorittåå myos silloin kun tavaravaunu 1 on lastauslaiturin tai muun vastaavan esteen kohdalla, joka peittåå sivupalkin 12 alueen. Siinå tapauksessa, ettå tavaravaunu ei ole lastauslaiturin kohdalla, voidaan kåyttovåline 3 tåsså toteu-tusmuodossa kytkeå myos suoraan kåyttåakseliin 5. Siinå kek-20 sinnon toteutusmuodossa, jossa kåyttåvåline 3 on sijoitettu rautatievaunun sivupalkkiin 12 tai sen låhelle, on kåyttåvå-lineen py6ritysakseli edullista sijoittaa osoittamaan vaunun sivusta 10 vinosti ulos- ja ylåspåin, jolloin kåyttovåline sijoittuu sellaiseen kohtaan ja asentoon, ettå sitå voidaan 25 kåyttåå myos rautatievaunun ollessa lastauslaiturin kohdal-la. Tårnån suunnan saamiseksi kåytt6vålineen akselille se on kytkettåvå kåyttdakseliin 5 vaihteistolla tai vastaavalla mekanismilla.The cover transfer mechanism 27 typically comprises one drive means 3, such as a hand crank or the like, for each movable roof part. According to the invention, the drive means 3 is preferably detachable and / or pivotable inside a structure, such as a center console or a side beam, on the side 10 of the railway carriage, so that it does not increase the width of the carriage during travel. In the embodiments of the figures, this rotatable drive means 3 can be connected to the shaft 24 and thereby by means of a chain drive 25 or a similar belt drive or by a gear-tooth gear 10 or in another suitable manner. In this transmission, which increases the distance H, the drive means 3 is sufficiently above the side beam 12 of the freight wagon, whereby it can be rotated even when the freight wagon 1 is at the loading dock or other similar obstacle covering the area of the side beam 12. In the event that the freight wagon is not at the loading dock, the drive means 3 in this embodiment can also be connected directly to the drive shaft 5. In the embodiment of the invention where the drive means 3 is located from the side 10 of the carriage obliquely outwards and upwards, the driving means being located in such a position and position that it can be operated even when the railway carriage is at the loading platform. In order to obtain the direction of vibration on the drive shaft, it must be connected to the drive shaft 5 by a gearbox or similar mechanism.

30 Kåyttdakseliin 5 on yhdistetty muuntomekanismi 4, jolla kåyttoakselin pyorimisliike muunnetaan kåyttdtankojen 6 ve-* to- tai ty6nt61iikkeeksi riippuen kateosien kulloisestakin asennosta ja kåyttoakselin py6rityssuunnasta. Kåyttotangot 6 ovat pååpiirteittåin my6s vaunun poikkisuuntaisia ja ne on 35 muuntomekanismista 4 poispåin olevista påiståån kytketty saranoilla tai nivelillå 28 vipuihin 7, jotka on toisesta pååståån ainakin kiertojåykåsti kiinnitetty kååntoakseleihin 8. Nåitå kåånt6akseleita 8 on tyypillisesti yksi vaunun kum- 5 S2665 mallakin puolella aina yhtå levittyvåå kateosaa 2 kohti, jolloin kåyttoakselin kierto saa mainitulla tavalla kåytto-tangot 6 tydntymåån tydntdliikkeellå T ulospåin tai veto-liikkeellå V sisåånpåin tai vastaavasti tydnto-veto-liik-5 keillå Ml, M2, jolloin kååntdakselit 8 kiertyvåt vipujen 7 vålityksellå vaunun pituussuuntaisten keskilinjojensa ympå-ri. Tåmå kååntdakselien 8 kååntdliike nostaa kateosat kul-loinkin tarkoitetulla tavalla liikutusasentoon tai laskee sulkuasentoon jollain sinånså tunnetulla kuvioissa ei-esite-10 tyllå tavalla.A conversion mechanism 4 is connected to the drive shaft 5, by means of which the rotational movement of the drive shaft is converted into the pulling or pushing movement of the drive rods 6 depending on the respective position of the roof parts and the direction of rotation of the drive shaft. The drive rods 6 are also generally transverse to the carriage and are connected at their ends remote from the conversion mechanism 4 by means of hinges or joints 28 to levers 7 which are at least one of the two shafts at least one of the shafts. towards the roof part 2, whereby the rotation of the drive shaft causes the drive rods 6 to be filled in the filling movement T outwards or in the traction movement V inwards in the said way, or ri. This pivoting movement of the pivot shafts 8 raises the cover parts to the movement position or lowers them to the closed position in a manner not known per se in a manner not known in the figures.

Tåmå jårjestely siis tarkoittaa sitå, ettå rautatievaunussa 1 on aina kutakin liikutusasentoon siirrettåvåå kateosaa 2 kohti yksi siirtomekanismi 27 ja tåmå siirtomekanismi siis 15 kåsittåå vaunun molemmilla puolilla kååntdakselit 8 sekå niitå kååntåvåt kåyttdtangot 6, muuntomekanismin 4 ja sitå kåyttåvån vaunun poikkisuuntaisen kåyttoakselin 5. Kuvioiden esimerkeisså, joissa on kuvattu keskikonsolilla ja kahdella liikutusasentoon ja sulkuasentoon siirrettåvållå kateosalla 20 2 varustettu vaunu 1, on siis kahdet siirtomekanismit 27.This arrangement thus means that the railway carriage 1 always has one transfer mechanism 27 for each roof part 2 to be moved to the movement position, and this transmission mechanism 15 thus comprises on both sides of the carriage in which a carriage 1 with a center console and two cover parts 20 2 movable to the movement position and the closing position is described, there are thus two transfer mechanisms 27.

Kuvion 2 toteutusmuodossa muodostuu muuntomekanismin 4 ruu-vielin 14 ja sen vastinelin 13 kåyttdakseliin 5 sisåltyvåstå ruuvikierukkaosuudesta 15 ja tåhån sovitetusta ja sen vaiku-25 tuksesta toimivasta hammaspydråstå 16, jonka kehållå on ruu- -- vikierukkaosuuteen sopiva likimain kehåviivaansa nåhden poi- kittainen hammastus. Vastinhammaspydrån 16 pydrintåakseli 9 on tyypillisesti kohtisuorassa kåyttoakselia 5 vastaan ja siten vaunun pituussuuntainen. Tåmån vastinhammaspydrån ul-30 kokehån låhellå hammaspydrån sillå pinnalla, joka on likimain vaunun poikkisuuntainen, on laakerointi- tai nivelkoh-tia 17a ja 17b, ja nåitå on kuvion toteutusmuodossa kaksi kappaletta toisiaan vastapååtå. Nåmå laakerointikohdat 17a ja 17b ovat såteen R etåisyydellå vastinhammaspydrån pyorin-35 tåakselista 9, jotta hammaspydrån kierto saisi aikaan kåyt-tdtankojen 6 tydnndn T tai vedon V kååntdakselin 8 kååntåmi-seksi. Nåmå laakerointikohdat 17a ja 17b voivat olla sijoi-tettuna vastinhammaspydrån kehålle esimerkiksi siten, ettå 92665 6 ne tietysså toiminta-asennossa sijaitsevat samalla vaaka-tasolla ja kåyttdtangot 6 niistå suoraan ulospåin vipuihin 7. Tåmå vastaa låheisesti kuviossa 2 esitettyå asentoa ja tållSin vivut 7 ovat kååntyneenå ulospåin ååriasentoonsa.In the embodiment of FIG. The pressure axis 9 of the mating gear 16 is typically perpendicular to the drive shaft 5 and thus longitudinal to the carriage. There are bearing or articulation points 17a and 17b on the surface of the counter-tooth hydrate ul-30 in the vicinity of the test gear, which is approximately transverse to the carriage, and in the embodiment of the figure there are two opposite to each other. These bearing points 17a and 17b are at a radius R from the axis 9 of the counter-rotating gear rotor-35, so that the rotation of the gear to effect the filling of the drive rods 6 or the traction V to turn the pivot shaft 8. These bearing points 17a and 17b can be arranged on the circumference of the counter-toothed hydrator, for example, so that in a certain operating position they are located in the same horizontal plane and the drive rods 6 are directly outside the levers 7. This corresponds to out to its outer position.

5 Kun kåyttoakselia 5 kierretåån niin paljon, ettå vastinham-maspyårå 16 pyorii kuvion 2 toteutusmuodossa myåtåpåivåån n. 180°, kiertyvåt laakerointikohdat 17a, 17b ylå- ja alakautta jålleen likimain vaakasuoriin kohtiin toisiinsa nåhden, mut-ta kåyttotangot 6 kulkevat tålloin laakerointikohdista vas-10 tinhammaspyorån vaunun poikkisuuntaisen pinnan poikki vipuihin 7. Tålloin vivut 7 ovat kåånnettyjå sisåånpåin ååriasentoonsa. Muodostamalla vastinhammaspyorån 16 kehålle laakerointikohdat 17a ja 17b sopivalle etåisyydelle R saadaan kåyttdtankojen tyonto- tai vetoliike suuruudeltaan halutuk-15 si. Riippuen muuntomekanismin 4 sijoituskohdasta ja vipujen 7 sijoituskohdasta voidaan laakerointien 17a ja 17b sijasta kåyttåå myos niveliå tai vastaavia. Vipujen 7 ja kåyttotan-kojen 6 liityntånå ovat laakerit tai nivelet 28. Ruuvi-kierukkaosuuden 15 sijasta voidaan tietenkin kåyttåå my6s 20 hammaspyoråå, jolloin muodostuu tavanomainen hammaspyorå-vaihteisto, mutta tilan kåytto on yleenså ruuvikierukkaa kåytettåesså edullisempaa.5 When the drive shaft 5 is rotated so much that the counter-tooth gear 16 rotates about 180 ° in the embodiment of Fig. 2, the rotating bearing points 17a, 17b again at the upper and lower sides at approximately 6ths intersect at approximately horizontal points. across the transverse surface of the tin gear carriage to the levers 7. In this case, the levers 7 are turned inwards to their outer position. By forming the bearing points 17a and 17b on the circumference of the mating gear 16 at a suitable distance R, the pushing or pulling movement of the drive rods of the desired size is obtained. Depending on the location of the conversion mechanism 4 and the location of the levers 7, joints or the like can also be used instead of the bearings 17a and 17b. The levers 7 and the drive rods 6 are connected to bearings or joints 28. Of course, instead of the screw-thread portion 15, 20 gears can also be used, thus forming a conventional gear gear, but the use of space is generally more advantageous than a screw screw.

Kuvioissa 3 ja 4 on kuvattu toinen keksinnån mukainen muun-25 tomekanismin 4 toteutusmuoto, jossa muuntomekanismin 4 ruu-vielin 14 ja sen vastinelin 13 muodostuvat ruuvikierukoista 18 ja 19.

Tåhån ensimmåiseen ruuvikierukkaosaan 18 on kyt-. ketty toinen ruuvikierukkaosa 19 tåsså tapauksessa siten, ettå ensimmåinen ruuvikierukkaosa on koirasruuvi ja toinen ruuvikierukkaosa 19 on naarasruuvi. Tåmå toinen ruuvikieruk-35 kaosa 19 on kiinnitetty vaunun 1 runkoon pyorimåttåmåsti siten, ettei se pååse pyorimåån ensimmåistå ruuvikierukka-osaa 18 pyoritettåesså, vaan liikkuu sitå pitkin pyorityksen aikana suuntiin Ml ruuvivålityksen vaikutuksesta. Tåmå pyo- 7 9266b rimåttomyys on edullisesti saatu aikaan vaunun pituuslinjan 1 suuntaisella akselilla 22, jonka ympåri tåmå holkkimainen toinen ruuvikierukkaosa 19 pååsee kallistumaan. Pyorimåtto-myys voidaan toteuttaa myos toisen ruuvikierukkaosan poikki-5 leikkausmuodolla. Tåmån toisen ruuvikierukkaosan 19 jatkeena poispåin ensimmåisestå ruuvikierukkaosasta 18 on ainakin yksi kåyttotanko 26, joka on kytketty yhteen vipuun 7 sen kåånto- akselista 8 poispåin olevaan nivelkohtaan 28. Tåmån lisåksi siinå kåånt6akselissa 8, johon kåyttotanko 26 on 10 kytketty on myds toinen vipu 7, joka on yhdistetty lisåkåyt-totangolla 23 vaunun toisella puolella olevaan kååntoakse-liin 8 siinå olevan vivun 7 vålityksellå.

Toisin sanoen, jos toinen kååntoakseli pyorii tietysså tilanteessa myotåpåivåån, pySrii toinen kååntoakseli vastapåivåån ja kåånteisesti. Tåsså rakenteessa siis ensimmåisen ruuvikierukkaosan 18 pySriminen saa aikaan toisen ruuvikierukkaosan 19 ja sen jatkeen 26 pySrimåttSmån 25 liikkumisen pitkin ensimmåistå ruuvikierukkaosaa, jolloin vaunun yhdellå puolella oleva kååntoakseli 8 pyorii, mikå liikuttaa lisåkåyttotangolla 23 vaunun toisella puolella olevaa kååntåakselia 8.Figures 3 and 4 illustrate another embodiment of the conversion mechanism 4 according to the invention, in which the screw 14 of the conversion mechanism 4 and its counterpart 13 are formed by screw coils 18 and 19. It first has a drive shaft 5 connected by a transmission 20, such as a chain drive 1. to the transverse first helical part 18, whereby the rotation of the drive shaft is also rotated by this helical part 18. This first helical part 18 is also connected. the second screw coil part 19 in this case such that the first screw coil part is a male screw and the second screw coil part 19 is a female screw. This second screw helix portion 19 is fixed to the body of the carriage 1 in a non-rotating manner so that it cannot rotate while rotating the first screw helix portion 18, but moves along it during rotation in the directions M1 due to screw transmission. This unsupportability of the pyo- 7 9266b is preferably provided by an axis 22 parallel to the longitudinal line 1 of the carriage, around which this sleeve-like second screw coil part 19 is allowed to tilt. The rotary mat can also be implemented in the cross-sectional shape of the second screw coil part. As an extension of this second screw helix part 19 away from the first screw helix part 18, there is at least one drive rod 26 connected to one lever 7 at a hinge point 28 remote from its pivot shaft 8. In addition, the hub 7 is connected by an auxiliary drive rod 23 to a pivot shaft 8 on the other side of the carriage via a lever 7 therein. If tåsså toteu-dosage form lisåkåyttotangon 23 decided from the kååntdakseleihin 8 KYT keviå levers merkitåån reference numerals 7a and 7b are 15 face to each other in such a way and working example ensimmåinen lever 7a is located kååntSakselista 8 to bottom and the second lever 7b kååntoakselista one side of the carriage 8 ylospåin to kååntoakselit 8 on different sides of the carriage, the movement M2 of the additional drive rod 23 makes it mirror-like with respect to the center line of the carriage length-20. In other words, if one pivot axis rotates in a certain situation on the day of the day, the other pivot axis rotates counterclockwise and vice versa. Thus, in this construction, the rotation of the first helical part 18 causes the second helical part 19 and its extension 26 to rotate along the first helical part, whereby the pivot shaft 8 on one side of the carriage rotates on the side of the carriage 8 on the second drive shaft.

The ends of the shaft 22 thus allow the extension 26 of the second helical part to tilt around the longitudinal line L of the carriage, which is the same as the direction of the shaft 22, and the second helical part 19 and 92665 8 to move its extension 32 along the slot 32. In the structure of Fig. 4, the screw coil part 19 and its extension 26 are rigidly connected to each other by the intermediate part 33.

It is also conceivable to have a structure in which there is no additional drive rod 23, but for example two second screw coil parts 19 of the type shown are connected to the first screw coil part 18 of the type shown in Fig. 3, which are extended by drive rods 26 in this case. there are two pieces, and the first screw helix part 18 of the container must be approximately in the middle of the width of the carriage. This last described embodiment can be further modified such that the first screw helix part 18 consists of one or two screw helix parts 20 belonging to the drive rod 5, to which two pieces of second screw helix parts are connected. 19 or its extension 26 is, of course, coupled to the carriage run-25 to be tilted about the longitudinal axis of the carriage, but non-rotatably about its axis lines 21, as described above. The second screw coil part is sleeve-like or, as shown in Fig. 3, includes only the sides to which the drive rod 26 is connected to allow a central angle change of the screw coil parts. The second screw coil part of My6s may be male threaded and the first screw coil part may be female threaded.
