Description
Izum se odnosi na jedan nasatavak za usisavač za prašinu, kod koga je usisavač postavljen ekscentrično na jedan zglob, tako da masa usisavača djeluje izvan težišta aparata, a posebno za električne strojeve za glačanje i poliranje za obradu podova pomoću većeg broja pločastih četaka, odnosno krugova za poliranje.
U tehnici su poznati različiti sustavi rasterećenja pomoću opruga. Tako prikazuje njemački uprabni model 3618803.4. na primjer, smanjenje sile za pomicanje nastavka usisavača prašine po podu pomoću jedne opruge.
Sustav za rasterećenje, koji bi masu jednog usisavača, ekscentrično priključenog na nastavak, raspodijelio na sve pločaste četke, odnosno krugove za poliranje, do sada još ne postoji.
Zbog toga što takav uređaj nedostaje, krugovi za poliranje se od toga kako na njih djeluje masa aparata različito brzo troše. To izaziva potrebu česte zamjene krugova za poliranje koji su zbog neravnomjerne raspodjele mase aparata djelomično jako istrošeni. Nabava ovih rezervnih dijelova je za korisnika povezana sa stalnim velikim troškovima.
Jednostrana raspodjela mase se negativno očituje i tako što kod obrade stroj "bježi" od željenog smjera kretanja. Ova se pojava može objasniti time, što križna ploča koja je opterećena više od drugih bude tako pritisnuta na pod, da djeluje kao pogonski element i zakrene stroj u stranu. Da bi mogao učinkovito raditi, korisnik stroja se mora stalno opirati tom zakretanju, što uzrokuje nepotrebna naprezanja.
Zbog toga je cilj izuma osigurati masu stroja da bude tako ravnomjerno raspodijeljenja, da se navedeni nedostaci više ne javljaju. Taj je cilj postignut izumom prikazanim u zahtjevu 1.
Podzahtjevi 2 do 5 prikazuju pogodne izvedbe izuma.
Prednost rješenja prema izumu sastoji se posebno u tome, što uslijed ravnomjerne raspodjele mase stroja na sve ploče za obradu više ne dolazi do jednostranog trošenja pojedinih ploča. Ploče se rjeđe moraju mijenjati, pa se troškovi za rezervne dijelove smanjuju. Aparat se više ne zanosi u stranu, što za korisnika znači bitno lakši i učinkovitiji rad.
Pomoću jednog prekidača, koji kod zaustavljanja kretanja aparata ovaj automatski isključuje, osigurano je da se on u stanju djelovanja cijele mase usisasavačkog uređaja na jednu točku nastavka za glačanje, ne pokrene sam od sebe iz te točke.
Predmet izuma će biti detaljnije objašnjen preko jednog primjera izvedbe prikazanog na crtežima. Pri tome:
- slika 1 prikazuje shematsku skicu stroja za glačanje i poliranje,
- slika 2 prikazuje pogled s donje strane na nastavak,
- slika 3 prikazuje pogled s bočne strane na sustav za rasterećenje,
- slika 4 prikazuje pogled s prednje strane na sustav za rasterećenje.
Na slici 1 prikazana je raspodjela sila u stroju za glačanje i poliranje, pri čemu F2 (4) prikazuje težište usisavača 2 izvan nastavka 1 za glačanje a F1 (3) težište nastavka 1 za glačanje. Uslijed ovih sila (3 i 4) sile nalijeganja na pod krugova 6 za glačanje su različite.
Da bi se ove sile izjednačile, na šarki 8 su postavljene opruge 11 za izjednačavanje. One pomaknu silu F2 (4) na silu F3 (5) na dršku i na težište nastavka 1, F1 (3).
U tom su cilju na okretnu osovinu 7 šarke 8 postavljene, u ovom slučaju dvije okretne poluge 9. Na njih djeluju preko vodilica 10 pritisne opruge 11. Isprekidane linije 13 sa oznakama stupnja radnog položaja šarke 8, pokazuju u produžetku 14 pripadajući položaj okretnih opruga 11 i vodilica 10 moraju se birati prema vrsti drugih komponenata i prema postavljenom problemu. Kod vodoravnog položaja šarke 8, pritisne opruge 11 su rasterećene, dok kod njegovog okomitog položaja malom raspodjelom sila osiguravaju stabilnost. Ako se aparat zaustavi, odnosno, šarka 8 sa usisivačem 2 se postavi u približno okomit položaj, pri radnom položaju između oko 60 i 80° jedna okretna poluga 10 će aktivirati prekidač 12 i isključiti aparat.
Claims (5)
1. Nastavak za usisavač za prašinu, na kome je usisavač ekscentrično postavljen na jednoj šarki, pri čemu masa usisavača djeluje izvan težišta aparata, naročito za električne strojeve za glačanje i poliranje s više pločastih četki ili krugova za poliranje, naznačen time, što je na šarku (8) postavljena jedna ili više opruga (11) koje raspodjeljuju masu usisavača, u ovisnost o radnom kutu šarke (8), na pločaste četke, odnosno krugove (6) za poliranje.
2. Nastavak prema zahtjevu 1, naznačen time, što opruge (11) zahvaćaju okretnu osovinu (7) šarke (8) preko vodilica (10) opruga, čiji broj odgovara broju opruga (11), a koje su preko okretnih poluga (9) povezane šarkom (8).
3. Nastavak prema zahtjevima 1 i 2, naznačen time, što opruge (11) kod okomitog položaja usisavača (2) prašine ne prenose sile.
4. Nastavak prema zahtjevima 1 do 3, naznačen time, što opruge (11) kod okomitog položaja usisavača (2) prašine prenose jednu silu koja podražava stabilnost cijelog aparata.
5. Nastavak prema zahtjevima 1 do 4, naznačen time, što jedna od okretnih poluga (9) pri kutu usisavača (2) prašine u odnosu na vodoravnu os od 60-80° aktivira prekidač (12) koji prekida dovod struje.
