Xa kufikelelwa ekuzikhuseleni kwimozulu, zimbalwa izinto eziyilwe eziye zamelana novavanyo lwexesha njengeambrela.Kangangeenkulungwane, esi sixhobo siphantsi besikhusela emvuleni, kwikhephu, naselanga, sisenza ingcwele ephathwayo ngokuchasene neminqweno yendalo.Kodwa emva kokulula kweambrela kukho ihlabathi elinomdla lobunjineli kunye noyilo, ngakumbi xa kuziwa kwisakhelo.Kweli nqaku, siza kuphonononga ubugcisa bokuyila iifreyimu zeambrela eziguquguqukayo, itekhnoloji esemva kwazo, kunye nefuthe abanalo kubomi bethu bemihla ngemihla.
I-Evolution ye-Umbrella Frames
Iiambrela zinembali ende nembali, ezisusela kumawaka eminyaka kwimpucuko yamandulo efana neMesopotamiya, iYiphutha neTshayina.Noko ke, kwaba yinkulungwane ye-18 awathi iambrela yale mihla esongwayo, njengoko sisazi namhlanje, yaqalisa ukubonakala.Uphuhliso lwezakhelo zesambrela luhambe kakhulu ukusukela ngoko, luvela kwizakhiwo eziqinileyo nezinzima ukuya kuyilo olukhaphukhaphu kunye noluguquguqukayo.
Eyona njongo iphambili yaso nasiphi na isakhelo sesambrela kukuxhasa i-canopy kwaye igcine i-taut, ukubonelela ngekhaka elomeleleyo ngokuchasene nezinto.Nangona kunjalo, ukuguquguquka kuye kwaba yinto ebalulekileyo ekuyilweni kweambrela, ngakumbi njengoko sijongene neemeko zemozulu ezingalindelekanga kunye nemimoya enamandla.Izakhelo zeambrela zesintu ezenziwe ngomthi okanye ngentsimbi zazisoloko zingenako ukugoba nokugoba, nto leyo eyayizenza zibe sesichengeni sokonakala kwimimoya ebhudla ngamandla okanye imvula enkulu.
Izinto eziphathekayo
Enye yezinto eziphambili ekuyileni iifreyimu zeambrela eziguquguqukayo kukukhethwa kwezinto eziphathekayo.Iiambrela zangoku zihlala zisebenzisa izixhobo ezifana ne-fiberglass, i-aluminiyam, kunye ne-carbon fiber kwiifreyimu zazo.Ezi zixhobo zinika ukudibanisa okufanelekileyo kwamandla kunye nokuguquguquka.
I-Fiberglass, umzekelo, lukhetho oludumileyo ngenxa yobunzima bayo kunye nokuguquguquka okumangalisayo.Xa iphantsi kokunyanzeliswa, i-fiberglass inokugoba kwaye ifunxe amandla ngaphandle kokwaphuka, iyenze ibe lolona khetho lubalaseleyo kwiimbambo zeambrela.I-aluminiyam kunye ne-carbon fiber nazo zixabiswa kwiipropati zazo ezikhaphukhaphu kunye nokukwazi ukumelana nokugoba ngaphandle kokuguqulwa okusisigxina.
