Twashoboraga kubwira shobuja gufata icyumweru cyo kuruhuka kubera ko twahinduye ijosi tuganira ku kazi na bagenzi bacu kuko intebe zacu zari nini cyane.Ariko kubera Thomas Jefferson, perezida wa gatatu wa Amerika, nta mahirwe nk'aya.
Mu 1775, Jefferson yahanze amaso intebe ya Windsor murugo, yitegereza intebe ya Windsor agira igitekerezo:
Iyi ni intebe ya Jefferson Yahinduwe.Urebye, ntabwo byahindutse cyane.Mubyukuri iyi ntebe ifite imyanya ibiri yintebe, ifatanye nicyuma cyo hagati, pulley ishyirwa mumurongo hagati yisura yubu, byongeye kubona ko igice cyo hepfo cyashizweho, igice cyo hejuru kizunguruka.Intangiriro yintebe ya swivel yavutse, abantu ntibagikeneye guhangayikishwa no kugoreka amajosi.
Ariko biratandukanye cyane n'intebe ya swivel - cyangwa, neza, intebe y'ibiro - aho tumarana amasaha umunani kumunsi.Nibura imiterere imwe yingenzi yabuze - uruziga.
Ninde wazanye igitekerezo cyo guhuza ibiziga kumaguru yintebe?Tugomba rero kunyerera tugerageza gutanga umusaruro kandi ntituzigera duhagarara?
Undi murimo uzwi cyane ku isi, se w'ihindagurika, Charles Robert Darwin.
Impinduramatwara mu nganda yazanye iterambere rikomeye ry’ubukungu bushya, kandi inganda zaguye ifasi n’ubucuruzi zishingiye kuri gari ya moshi zoroshye.Boss yahise atekereza ati: Ntabwo byari gutanga umusaruro gukoresha igihe cyurugendo kugirango wicare urangize impapuro?
Thomas Warren rero yaje mu bucuruzi.Isosiyete ye, Isosiyete y'Abanyamerika Intebe, yakoze intebe ya gari ya moshi yashyizemo udushya amasoko mu ntebe zo kwicara kugira ngo gari ya moshi ihinduke.Abakozi bagomba gukora kuri gari ya moshi.
Hashingiwe kuri ibyo, Thomas Warren yahimbye intebe yambere yibiro byamateka.Ifite hafi ibintu byose byingenzi biranga intebe yacu y'ibiro bigezweho - irahindukira, iranyerera, kandi ifite intebe yoroshye.
Igitekerezo cy'uko kwicara neza biganisha ku bunebwe byari bimenyerewe muri 1920.
Umugabo witwa William Ferris yateye imbere kugirango ibintu bishoboke.Yashizeho Intebe ZIKORESHWA.Reba umutwe munini kuriyi posita.Ninde muntu wicaye kuriyi ntebe?"Abakozi bashya, bishimye, bakora kandi batanga umusaruro" abakozi bo mu biro.
Biragaragara ko ari isoko yububabare bwisoko ridakora neza nindwara zakazi.
Ibitekerezo by'ikoranabuhanga birahinduka.Ubushakashatsi ku mibanire myiza hagati y’umuntu n’imashini bwageze ku rwego rwo hejuru mu Ntambara ya Kabiri y'Isi Yose uko inganda zagendaga ziyongera.Nyuma y’Intambara ya Kabiri y'Isi Yose, "ergonomique" ntiyari ikiri ijambo rikomeye, ahubwo yari ijambo ryemewe muri buri gice.
Kandi rero, mu 1973, havutse intebe y'ibiro.
Umucyo wiyi ntebe biterwa na: kuryama hejuru yumutwe, hejuru yintebe hejuru hamwe na pulley, bigufi kandi byerekana neza, ibara ryiza.Abashushanya kandi bakoresha uburyo bwiza kumeza, imashini yandika nibindi bikoresho byo mu biro, bizeye guhindura ibiro muri paradizo, gukaraba.
Intebe y'ibiroyagize impinduka nyinshi zishingiye ku kuzunguruka, pulley n'uburebure bwo guhindura izi nyubako shingiro kuva icyo gihe, kandi yabaye intebe y'ibiro byubu.
