Mai ka hana ʻana o nā kaʻa kaʻa, ʻoi aku ka maikaʻi o nā kānaka no ka lawe ʻana a me ka leʻaleʻa, ʻoi aku ka maikaʻi ma hope o ka lilo ʻana o ka paikikala i mea hoʻokūkū hoʻokūkū, makemake nui ka poʻe iā ia. Eia naʻe, ma ke ʻano he haʻuki me nā hopena wikiwiki, ua lilo ka palekana i mea koʻikoʻi. No laila, manaʻo ka poʻe i nā mahiole. ʻO ka hiki ʻana mai o nā mahiole kaʻa kaʻa ʻaʻole wale e hōʻoia i ka palekana o nā mea holo kaʻa, akā hoʻomaikaʻi pū i ka hana o nā mea holo. ʻO ka maikaʻi o ka hoʻohana ʻana i nā mahiole i ʻike mua ʻia e ka poʻe holo kaʻa huila kahiko ma kekahi mau kalapu ma mua o ka makahiki 1880, a ma hope mai me ka piʻi ʻana o nā ala ʻala a me nā ala pōhaku, ua piʻi aʻe ka ʻeha o ke poʻo i ka wā kaʻa paikikala. , ua puka mai ka mahiole paikikala pith.
ʻO ka pith kahi mea hoʻopololei e komo i ka ikaika o ka hopena, akā ua hāʻawi koke ka mahiole i kahi hoʻolālā ʻili i hoʻomaka ʻia e kapa ʻia ʻo "hairnet" no ke ʻano o ka ʻupena ma ke poʻo. ʻO ka pahu ʻili lōʻihi like. Aia ka padding foam i ʻōwili ʻia i ka ʻili palupalu. Mālama kēia i nā pepeiao o ke kanaka kaʻa kaʻa i ʻeha i ka hāʻule ʻana mai ka hakakā ʻana a i ʻole ka ʻeha. Akā naʻe, ʻoi aku ka maikaʻi o kāna hana shockproof.
He mea hoʻomohala koʻikoʻi ka mahiole palupalu a ʻano like me ke kīʻaha i hana ʻia me ka mea polystyrene i hoʻopuni ʻia e nā mea elastane synthetic (LYCRA). A laila e hoʻokomo i kahi pahu pahu i loko.
ʻO ke kūlana kūpaʻa kūʻē o nā mahiole paʻa kaʻa a me ka paʻa o nā kaula i hoʻopaʻa ʻia e ka US Consumer Product Safety Commission (CPSC) i ka waena o 1970s. I kēlā manawa, hoʻokahi wale nō mahiole kaʻa kaʻa māmā i kū i kēia maʻamau. Akā, ʻaʻole komo nā kaʻa kaʻa i nā mahiole. No ka mea, ua kaumaha kēia mahiole a ʻaʻole hanu.
No ka hana ʻana i kēia, hana mua ka mea hana i ka pūpū mai ka plastik ABS, e hoʻomohala ana i kahi mahiole paʻa paʻa CPSC i hana ʻia me ka polystyrene foam. Ma hope iho, ua hoʻemi nui ʻia ke kaumaha o ka mahiole i ka mea hou o ka pūpū PVC a me ka polycarbonate kumu kūʻai nui. ʻO ka ʻōlelo maʻamau, pono e hiki i ka mahiole paʻa kaʻa ke kū i ʻelua hui ʻana. ʻO ka mea mua i ka wā e hui ai me nā kaʻa kaʻa ʻē aʻe a i ʻole nā kaʻa, a ʻo ka lua i ka wā e hāʻule ai ka mea holo kaʻa i kona iho ponoʻī, loaʻa kēia mau mea i ka hopena cushioning maikaʻi i nā hopena ʻelua.
Ua loli nui ke ʻano o ka mahiole paikikala mai kona hoʻomaka ʻana. He wā lōʻihi ka hele ʻole ʻana o nā mahiole poepoe. I kēia manawa, ʻoi aku ka liʻiliʻi o ka mahiole ma ka ʻaoʻao a ua loli nui nā puka makani, ʻoluʻolu loa, hanu, aerodynamic.
Ma waho aʻe o nā mahiole paikikala alanui, me ka hiki ʻana mai o ka holo kaʻa mauna, ua ʻike pū ʻia kona mau mahiole. E like me ko lākou nui nui, ʻoi aku ka liʻiliʻi o ka aerodynamic ma mua o nā mahiole alanui. ʻO ka hana nui o kēia mau mahiole, ʻo ia ka ʻae ʻana i ka hou e hoʻoheheʻe ʻia me ka wikiwiki haʻahaʻa i nā piʻi wela.
