Description

Predmetom vynálezu je zariadenie na pritláčanie veka manipulačného otvoru.An object of the invention is a device for pressing the lid of a handling opening.

Na pritláčanie odklopných viek manipuláěných otvorov sú známe zariadenia skrutkové, vačkové alebo kulisové. Skrutkové zariadenie je málo citlivé na výrobné nepřesnosti, jeho otváranie a zatváranie vyžaduje menšiu ovládaciu silu, ale dlhšiu dobu. Vačkové a kulisové zariadenia zas<a vyžadujú na otváranie a zatváranie poča3 kratšej doby vačšiu ovládaciu silu. Sú'tiež citlivejšie na výrobné nepřesnosti, ktoré síažujú montáž vo výrobnom závode.Screw, cam or sliding devices are known for pushing the hinged lids of the handled openings. The screw device is poorly susceptible to manufacturing inaccuracies, requiring less control force but longer time to open and close. In turn, cam and gate devices require greater control force to open and close in less time. They are also more sensitive to manufacturing inaccuracies that hamper assembly at the factory.

Zariadenie podía vynálezu odstraňuje horeuvedené nedostatky. Jeho podstatou je,.že rameno veka,je jedným koncom otočné uložené na vodorovnom čapě. Na druhom konci má pevný čap, βThe device according to the invention removes the above drawbacks. Its essence is that the lid arm is pivotally mounted on a horizontal pin at one end. At the other end it has a fixed pin, β

zachytený hákovadlom, otočné uloženám na výstredníku. Hákovadlo je axiálně uložené medzi třecími obloženiami. Výstredník je pevne spojený s hriadelom, otbčne uloženým v ložiskách na základnej doske. V strednej časti ramena veka je posuvné uložená stopka, ktorá má na svojej hornej závitovej časti matice k nastaveniu vlastnej polohy. Na dolnej závitovej časti má tanierovú maticu na nastavenie sily hlavnej pružiny, pre pritlačenie veka na základná došku.caught by a hook, rotatable on the eccentric. The hook is axially mounted between the friction linings. The eccentric is rigidly connected to a shaft that is embedded in bearings on the motherboard. A shank is displaceably disposed in the central portion of the lid arm, which has nuts at its upper threaded portion to adjust its own position. On the lower threaded part, it has a disc nut to adjust the force of the main spring to press the lid onto the base thatch.

Používáním zariadenia podía vynálezu zmenší sa citlivosí na výrobné nepřesnosti, lebo poloha veka v osovom smere a přítlačná sila sú nastavitelné pri montáži. Doba ovládania je malá, rovnako ako u vačkového alebo kulisového ovládania, ale ovládacia sila je podstátne menšia, čo vyplývá z charakteristiky výstredníka. Hlavnou výhodou ale je, že hákovadlo, uložené na výstredníku a zvierané třecími obloženiami, sa pri otváraní oddaluje od pevného čapu viac, než je minimálně nutné, a preto pri zatváření sa každopádně dostane s ním do záběru. <The use of the device according to the invention reduces the sensitivity to manufacturing inaccuracies since the position of the lid in the axial direction and the thrust force are adjustable during assembly. The actuation time is small, as in the case of a cam or sliding actuator, but the actuating force is substantially smaller, which results from the eccentric characteristic. The main advantage, however, is that the hook placed on the eccentric and clamped by the friction linings moves away from the fixed pin more than minimally when opening, and therefore in any case it engages with the pin. <
