Description

Strømbryter manøvrert av vibrasjoner eller rystelser. Circuit breaker operated by vibrations or shocks.

Oppfinnelsen vedrbrer strdmbry tere for masKiaer, hvxiite Lryiere manovreres av vibrasjoner eller rystelser og arbeider som e; tyngdekraftpåvirket relé med en i tyngdekraf ire tningen bevegelig og i et, fjasende organ opphengt masse. The invention relates to circuit breakers for machines, where the actuators are operated by vibrations or shocks and work as e; gravity-affected relay with a mass that is movable in the force of gravity and suspended in a moving body.

Slike brytere kjennes fra tidligere i flere utfcrelser. Det er oppfinnelsens hensikt å tilveiebringe en slik bryter som er enk-lere, solidere og har en sikrere funksjon enn de tidligere kjente. Such switches are known from the past in several versions. It is the purpose of the invention to provide such a switch which is simpler, more solid and has a more secure function than the previously known ones.

Ifolge oppfinnelsen foreslåes det således at en bryter av oven-nevnte slag anordnes således at en i lengderetning forskyvbar manbverstav for strbmbryteren er utformet med en uttagning eller skulder i eller mot hvilken en fra den fjærende masse fremsprin&end del er anordnet for å rage inn ved hjelp av det fjærende organ, jjhvilken stav er anordnet forskyvbar'mot virkning av et annet fjæij-lorgan, hvorved massens fremspringende del ved vibrasjoner eller rystelser i tyngdekraftretningen fjærer ut av inngrep med uttag- j ningen eller mot skulderen på staven, slik at denne stav av det<j>åndre fjærende organ forskyves for omstilling av strbmbryteren. According to the invention, it is therefore proposed that a switch of the above-mentioned type be arranged so that a longitudinally displaceable manbverbar for the strbmbverbar is designed with a recess or shoulder in or against which a part projecting from the springy mass is arranged to project in by means of the springing member, jwhich rod is arranged displaceable'against the action of another fæij-lorgan, whereby the projecting part of the mass springs out of engagement with the socket or against the shoulder of the rod by vibrations or shakes in the direction of gravity, so that this rod of the <j>another springy member is displaced to adjust the power switch.

Strømbryteren blir .særlig enkel i sin oppbygning, om dertil det jannet fjærende organ er utformet som .en kontaktfjær i strdmbryteij-'en, samvirkende med en andre kontaktfjær, som er elektrisk isolert ifra den fbrste kontaktfjær. The circuit breaker becomes particularly simple in its structure, if the spring-loaded member is designed as a contact spring in the circuit breaker, cooperating with a second contact spring, which is electrically isolated from the first contact spring.

For strbmbryterens praktiske bruk er det også fordelaktig, om deri andre, fortrinnsvis stavformet utformete del har et utenfor strbni-jbryterens hus ragende parti, som utgjor tilbakestillingsknapp forj ;5lutting av strbmkretsen til maskinens drivmotor. ! For the circuit breaker's practical use, it is also advantageous if the other, preferably rod-shaped, part has a part projecting outside the circuit breaker's housing, which constitutes a reset button for switching the circuit of the machine's drive motor. !

;For å sikre at strbmbryteren arbeider på bnsket måte, bor dertil-massen vsre anordnet bevegelig med et bestemt spillerom i alle retninger perpendikulært på tyngdekraftens retning. To ensure that the circuit breaker works in the desired way, the mass must be arranged to move with a certain amount of play in all directions perpendicular to the direction of gravity.

,3a?rlig gunstig har strbmbryteren vist seg å vai re i det tilfelle, ,3 years favorable, the circuit breaker has proven to be in that case,

.da den er festet til en med en horisontal vasketromrnelaksel forsynt, sentrifugerende vaskemaskins trommel understøttende stativ-: del og er innkoblet i strbmtilfbrselen til vasketrommelena driv- ] jmotor, ved at den vandring på underlaget, som vaskemaskiner av j jdette slag ellers kunne gjore ved sentrifugering med skråbelastetj .vasketrommel helt har kunnet elimineres', J i i !0m vasketbyet i en sådan vaskemaskin skulle legge seg så usymme-trisk i trommelen, således at hele maskinen begynner å hoppe, slå,r strbmbryteren ifblge denne utfbrelse av oppfinnelsen umiddelbart ifra vaske trommelens drivmotor, slik at maskinen stanser. Vaske- j 'tbyet kan deretter omplaseres i trommelen for hånd og strbmbryt-•etens stavformete del trykkes inn for hånd, for maskinen igjen j begynner å arbeide. '• .as it is attached to a centrifugal washing machine drum supporting rack part provided with a horizontal washing drum shaft and is connected to the power supply to the washing drums drive motor, by moving on the surface, which washing machines of this type could otherwise do by centrifugation with an inclined loadj .washing drum has been able to be completely eliminated', J i If the laundry in such a washing machine were to settle so unevenly in the drum, so that the whole machine starts to jump, according to this embodiment of the invention, the circuit breaker is switched off immediately from the washing drum's drive motor, so that the machine stops. The laundry can then be repositioned in the drum by hand and the rod-shaped part of the switch pressed in by hand, for the machine to start working again. '•

I Oppfinnelsen skal nedenfor beskrives i detalj i forbindelse med : anvendelse som en sådan nbdsstrombryter for en slik vaskemaskin, '! i som har en ' roterende eller oscillerende vasketrommel.'i The Invention shall be described below in detail in connection with : application as such a nbds circuit breaker for such a washing machine, '! i having a ' rotating or oscillating washing drum.'i

jVed mange slike maskiner har det vist seg nodvendig å forankre ;disse til underlaget med bolter, f.eks. til et fundament, en opp-1vaskbenk e.1. Grunnen til dette.har vært at om vasketrommelen i s: kråbelastes, • eksemp' elvis ved uheldig ilegging av vaskegodset i<i>' j trommelen, har hele maskinen "vandret" på underlaget, på grunn j lav utillatelig store rystelser.<1>With many such machines, it has proved necessary to anchor them to the ground with bolts, e.g. for a foundation, an up-1 sink e.1. The reason for this has been that if the washing drum is overloaded, for example by accidentally placing the laundry in the drum, the whole machine has "wandered" on the surface, due to unacceptably large vibrations.<1>

■ . ■ ij Ved denne utfore.lsesform av oppf innelsen er nevnte ulempe elimi-; nert ved at strømbryteren stopper maskinen, om trommelen skråbe-i lastes og slike rystelser oppstår. I ir IUtforelsesformen kjennetegnes videre ved at massen ved maskinensjrystelser skiller strømbryterens kontaktfjærer fra hverandre og bryter motorens strbmtilforsel. ■ . ■ ij In this embodiment of the invention, the aforementioned disadvantage is eliminated; caused by the circuit breaker stopping the machine, if the drum is loaded at an angle and such vibrations occur. In the ir I embodiment, it is further characterized by the fact that the mass separates the circuit breaker's contact springs from each other during machine vibrations and interrupts the motor's power supply.
