TEATTERILAVA - TEATERSCEHTHEATER STAGE - TEATERSCEH

Tämän keksinnön kohteena on teatterilava, joka käsittää joukon rinnakkaisia ruuvikäyttöisiä saksipöytiä, joista jokaisella on oma ruuviin kytketty käyttökoneisto ja jossa saksipöytien liike on synkronoitu käyttämällä käyttökoneistoina sähköhydraulisia askelmoottoreita, ja jossa jokaisella lavayksiköllä on kaksi toistensa yläpuolella sijaitsevaa toisiinsa laakeroitua saksielintä ja kummallakin saksielimellä on oma nivelvar-sipari.The present invention relates to a theater stage comprising a plurality of parallel screw-operated scissor tables, each with its own screw-driven drive mechanism, in which the movement of the scissor tables is synchronized using electro-hydraulic stepper motors as drive mechanisms. Sipari.

Tämän keksinnön tarkoituksena on aikaansaada uudentyyppinen teatterilava, jossa pystysuunnassa liikutettavat saksipöydät ovat yksinkertaisilla ratkaisuilla turvallisesti ja käyttövar-masti liikutettavissa ja tukevasti pidettävissä määrätyissä tasoissa.The object of the present invention is to provide a new type of theater stage in which vertically movable scissor tables can be safely and reliably moved and held firmly in certain levels by simple solutions.

Eräänlainen tämäntapainen teatterilavajärjestelmä on esitetty US-patentissa 3 812 631.One such theater stage system is disclosed in U.S. Patent 3,812,631.

Keksinnön mukaiselle teatterilavalle on tunnusomaista se, että ylemmän saksielimen nivelvarsiparin alempi pää on nivelletty sraksielinten toiseen yhteiseen nivelpisteeseen ja että alemman saksielimen nivelvarsiparin ylempi pää on nivelletty saksi-elinten vastakkaiseen yhteiseen nivelpisteeseen ja että sama ruuvi vaikuttaa molempiin nivelvarsipareihin.The theater stage according to the invention is characterized in that the lower end of the upper scissor member articulated arm pair is articulated to the second common articulation point of the scissor members and that the upper end of the lower scissor member articulated arm pair is articulated to the opposite common articulation point of the scissor members and the same screw acts.

Keksinnön avulla on pöytien asennot sekö erikseen että toisiinsa verrattuna aina oikeissa korkeuksissa, koska askelmoot-tori mekaanisen ruuvin yhteydessä ei aiheuta pystysuuntaisia virheitä pöydille. Hydraulinen askelmoottori ei pysähdy ennenkuin se on pyörittänyt ruuvia määrätyn kierrosluvun, jolloin pöytä varmasti jää halutulle korkeudelle. Kun osa tai kaikki pöydät halutaan samalle tasolle ne myöskin askelmoottorin ansiosta asettuvat samalle tasolle erittäin suurella tarkkuudella. Saadaan myös yhdellä ja samalla ruuvilla nostoliikkeet vaikuttamaan molempiin saksielimiin, jolloin voimat jakautuvat tasaisemmin koko nostojärjestelmään.By means of the invention, the positions of the tables, both separately and in relation to each other, are always at the correct heights, because the stepper motor in connection with the mechanical screw does not cause vertical errors on the tables. The hydraulic stepper motor will not stop until it has rotated the screw to a certain speed, so that the table is sure to stay at the desired height. When some or all of the tables are desired at the same level, they are also placed on the same level with very high precision thanks to the stepper motor. With the same screw, the lifting movements can also be applied to both scissor members, so that the forces are more evenly distributed throughout the lifting system.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, jossaThe invention will now be described by way of example with reference to the accompanying drawing, in which

Kuvio 1 esittää teattei-ilavan osaa yksinkertaistettuna ja vinosti ylhäältä katsottuna.Figure 1 shows a part of teatte-Ilava in a simplified and oblique view from above.

Kuvio 2 esittää saksipöytää sivulta katsottuna.Figure 2 shows a side view of a scissor table.

Teatterilava käsittää joukon rinnakkaisia ruuvikäyttöisiä sak-sipöytiä 1, joista jokaisella on oma ruuviin 2 kytketty käyt-tökoneisto 3. Saksipöytien 1 liike on synkronoitu käyttämällä käyttökoneistona 3 sähköhydraulisia askelmoottoreita. Askel-moottoriin kuuluu sähköisesti toimiva puissimoottori, joka toimii sähköisillä impulsseilla ja ohjaa hydraulisesti toimivan käyttömoottorin kiertoliikkeitä ennalta annettujen ohjeiden mukaisesti. Käskyjen ja ohjauksien jälkeen tiedetään aina missä korkeudessa pöytä on. Askelmoottorit ovat sähköisesti ohjattavissa yhdestä ja samasta ohjauspulpetista. Pöytien ruuvit 2 on liikkeen pysähdyttyä järjestetty automaattisesti lukittaviksi ruuvin akselilla olevalJa jarrulla 4.The theater stage comprises a number of parallel screw-operated scissor tables 1, each of which has its own drive mechanism 3 connected to the screw 2. The movement of the scissor tables 1 is synchronized by using electro-hydraulic stepper motors as the drive mechanism 3. The stepper motor includes an electrically operated wood motor that operates on electrical impulses and controls the rotational movements of the hydraulically operated drive motor according to predetermined instructions. After the commands and controls, it is always known at what height the table is. Stepper motors are electrically controllable from one and the same control panel. The screws 2 on the tables are arranged to be locked automatically with the brake 4 on the shaft of the screw when the movement has stopped.

Ruuvi 2 vaikuttaa saksipöydän niveltankoihin 5, 6, 7, 8 nivel-varsien 9, 10, 11, 12 avulla, jolloin pöydän liike pysyy lineaarisena ruuvin kiertoliikkeeseen verrattuna. Näinollen tulee myöskin useampien pöytien yhtäaikaiset liikkeet toisiinsa verrattuna pysymään saman suuruisina ja kokonaisvaikutelma teat-terilavan muutoksessa on tasainen ja hallittu.The screw 2 acts on the articulated rods 5, 6, 7, 8 of the scissor table by means of the articulated arms 9, 10, 11, 12, whereby the movement of the table remains linear with respect to the rotational movement of the screw. In this way, the simultaneous movements of several tables compared to each other will also remain the same and the overall impression of the change of the theater stage will be smooth and controlled.

Alan ammattimiehelle on selvää, että keksinnön erilaiset sovellutusmuodot voivat vaihdella j älj empänä esitettävien patenttivaatimusten puitteissa. Niinpä tätä järjestelmää voidaan sinänsä tunnetulla tekniikalla edelleen kehittää esim. varustamalla ohjauspulpetti muistilla, joka sisältää teatteri-ohjelmiin tarvittavat muutokset teatterilavassa, jolloin muutokset tapahtuvat vaivatta ja nopeasti.It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the appended claims. Thus, this system can be further developed by a technique known per se, e.g. by equipping the control panel with a memory which contains the changes required for theater programs on the theater stage, whereby the changes take place effortlessly and quickly.
