Abstract
Účelom riešenia je do značnej miery odstranit nepřesnost optiokej sústavy projekčných prístrojov vzniklá, výrobnými toleranciami mechanických a optických dielcov, a tak zaistiť konštantnú zjustovanú polohu zrkadla a vlákna žiarovky. Tento účel je docielený uchytením gutového zrkadla v držiaku tvaru obráteného taniera, pomocou kuželovej pružiny. Vonkajší rozměr širšej časti kuželovej pružiny je vačší, ako vnútorný rozměr valcovej časti držiaka. Pružina svojou íunkciou upevňuje zrkadlo v držiaku, vymedzuje jeho osovú vol'u a zároveň dotláča sústavu do polohy zjustovanej pomocou skrutiek po vonkajšej straně držiaka. Tým sa docieli konštantná zjustovaná poloha zrkadla a vlákna žiarovky aj pri otrasoch počas dopravy a prenášania prístroja. Zároveň sa zjednoduší montáž uvedených dielcov optickej sústavyThe purpose of the solution is to a large extent to remove the inaccuracy of the projection system optics device tolerances mechanical and optical parts and thus to provide a constant position bulbs and filament lamps. This purpose is achieved by gripping the mirror in an inverted plate holder by means of conical spring. External dimension wider part of the conical spring is bigger than the inner one the size of the cylindrical part of the holder. Spring its function fixes the mirror in the holder, it defines its axis and at the same time presses the system to the position of the assisted position screws on the outside of the bracket. This results in a constant, staggered position bulbs and filament lamps also in shocks during transport and carrying the device. At the same time simplifies the assembly mentioned optical system components
Description
Vynález sa týká uchytenia gulOvého zrkadla v projekčných prístrojoch.BACKGROUND OF THE INVENTION The present invention relates to the mounting of a ball mirror in a projection apparatus.
Doteraz známe uchytenia guIového zrkadla v projekčných prístrojoch sú převedené viacerými sposobmi. Například pomocou priskrutkovaného planžetu, plechu, alebo pomocou výstupkov vytvořených v bočnej stene držiaka.Previously known ball mirror mounts in projection apparatuses are converted in several ways. For example, by means of a screwed-on foil, sheet metal, or by means of projections formed in the side wall of the holder.
Táto sústava je zpravidla uchytená o základnu pomocou troch alebo štyroch justážnych skrutiek, na ktorých sú nasunuté pružiny. Sústava je odtláčaná od základné do zjustovanej polohy ohniska zrkadla a vlákna žiarovky. Žiarovka je zpravidla uchytená o základňu samostatným držiakom.This assembly is generally fixed to the base by means of three or four adjustment screws on which the springs are inserted. The assembly is pushed away from the basic to the cone-shaped focal point of the mirror and filament lamp. The bulb is usually attached to the base by a separate holder.
Uvedené uchytenia zrkadla vyžadujú komplikovanú montáž dielcov a nezabezpečujú presnú osovú polohu zrkadla v držiaku z důvodov výrobných toleranci!.The above-mentioned mirror mounts require complicated assembly of parts and do not ensure the exact axial position of the mirror in the holder due to manufacturing tolerances !.
Takéto uloženia zrkadla sú převedené s volbu, ktorá vnáša do optického systému nepřesnost.Such mirror mounts are converted with an option that brings inaccuracy to the optical system.
Tieto nedostatky do značnej miery odstraňuje riešenie podfa tohto vynálezu, ktoré spočívá v uchytení guTového zrkadla v projekčných prístrojoch pozostávajúce z gul'ového zrkadla, držiaka, kuželovej pružiny, skrutiek a základní.These drawbacks are largely overcome by the solution of the present invention which consists in attaching a ball mirror in projection apparatuses consisting of a ball mirror, bracket, conical spring, screws and base.
Podstata vynálezu spočívá v tom, že gulové zrkadlo je uchytené v držiaku pomocou širšej časti kuželovej pružiny, pričom sústava je k základní upevněná skrutkami po vonkajšej straně držiaka tak, aby sa užšia část kuželovej pružiny opierala o základňu.The principle of the invention is that the ball mirror is mounted in the holder by means of a wider part of the conical spring, the assembly being fixed to the base by screws on the outside of the holder so that the narrower part of the conical spring is supported on the base.
Výhoda tohto riešenia spočívá v tom, že pružina svojou funkciou vymedzuje osovú volu guIového zrkadla v držiaku tvaru obráteného taniera, čím zaisťuje konstantou zjustovanú polohu ohniska zrkadla voči vláknu žiarovky. Tým odstraňuje nepřesnost, vnášanú do systému z dóvodov výrobných tolerancií.The advantage of this solution is that the spring defines by its function the axial steerage of the spherical mirror in the inverted plate holder, thereby ensuring a constant-focused position of the focus of the mirror relative to the filament of the bulb. This eliminates the inaccuracy introduced into the system due to manufacturing tolerances.
Příklad uchytenia guIového zrkadla v projekčnom přístroji je zobrazený na priloženom náčrtku, kde gulové zrkadlo 1 je uchytené v držiaku 2, tvaru obráteného taniera, pomocou širšej časti kuželovej pružiny 3. Sústava je k základní 4 upevněná pomocou skrutiek 5. Žiarovka 6 je k základní 4 připevněná pomocou samostatného držiaka 7.An example of mounting a ball mirror in a projection apparatus is shown in the enclosed sketch, where the ball mirror 1 is mounted in the inverted plate-shaped holder 2 by the wider part of the conical spring 3. The assembly is fixed to the base 4 by means of screws 5. attached by means of a separate holder 7.
Vonkajší priemer širšej časti kuželovej pružiny je vačší ako vnútorný priemer držiaka.The outer diameter of the wider portion of the conical spring is larger than the inner diameter of the holder.
Riešenie podlá tohto vynálezu je možné využívat hlavně v projekčných prístrojoch.The solution according to the invention can be used mainly in projection devices.
