A umnyango Ima (futhi isivalo sesicabha, ukuma emnyango noma isigaxa somnyango) kuyinto noma into esetshenziselwa ukugcina umnyango uvulekile noma uvaliwe, noma ukuvimbela umnyango ekuvulekeni kakhulu. Igama elifanayo lisetshenziselwa ukubhekisela esitsheni elincanyana elakhiwe ngaphakathi kohlaka lomnyango ukuvikela umnyango ekungeneni lapho uvaliwe. I-doorstop (esetshenzisiwe) ingaba ibakaki elincane noma ucezu lwensimbi olungama-degree angama-90 olusetshenziswe ohlakeni lomnyango lokumisa umnyango ekushingizeleni (ohlangothini olubili) nokuguqula lowo mnyango uye esiqondisweni esisodwa (in-swing Push noma ukudonsa ukuphuma)Ukubamba iminyango

Isicabha singamiswa ngophawu lomnyango oluyinto nje esindayo eqinile, efana nerabha, ebekwe endleleni yomnyango. Lezi zitobhi zithuthukiswe kakhulu.

[1] Ngokomlando, izitini eziholayo bekuyizinketho ezithandwayo uma zitholakala.

[2 Kodwa-ke, njengoba kuvezwe ubuthi bomthofu, lokhu kusetshenziswa kuyekiswe kakhulu.

[3] Enye indlela ukusebenzisa i- ukuma emnyangookuyi-wedge encane yokhuni, irabha, indwangu, upulasitiki, ukotini noma enye into. Ama-wedge enziwe alezi zinto atholakala kakhulu. I-wedge ikhahlelwa endaweni futhi amandla ezansi omnyango, manje aseminyene phezulu phezulu esitobhini somnyango, unikeza ukungqubuzana okwanele ukuze kungagudluki.

[4] Isu lesithathu ukuhlomisa umnyango uqobo ngenqubo yokumisa. Kulokhu, ibha yensimbi emfushane eboshwe ngenjoloba, noma enye into exubana kakhulu, inamathiselwe kwihibe eliseduze nesisekelo somnyango maqondana nomnyango wesicabha nasohlangothini lomnyango oqonde ovalweni. Lapho umnyango uzogcinwa uvulekile, umgoqo uvulwa phansi ukuze isiphetho senjoloba sithinte phansi. Kulokhu kulungiswa, ukunyakaza okuqhubekayo komnyango oya ekuvaleni kwandisa amandla ekugcineni kwenjoloba, ngaleyo ndlela kwandise amandla okulwa aphikisana nokunyakaza. Lapho umnyango uzovalwa, isitobhi sikhishwa ngokucindezela umnyango uvuleke kancane, okukhipha isitobhu nokuvumela ukuthi uphenye ubheke phezulu. Uhlobo olusha lokuhlomisa umnyango ngenqubo yokumisa ukunamathisela uzibuthe ezansi komnyango ohlangothini oluvulekela ngaphandle olunamathisela komunye uzibuthe noma okomazibuthe odongeni noma ihabhu elincane phansi. Uzibuthe kufanele uqine ngokwanele ukubamba isisindo somnyango, kepha ubuthakathaka ngokwanele ukuthi ungasuswa kalula odongeni noma kuhabhu
