Ungabakhetha kanjani ubukhulu bedeski lengane nomuntu omdala

Send

Ngokwezibalo, iningi le-pathologies yohlu lomgogodla luthuthuka ngenxa yokuthi umuntu akahlali kahle etafuleni. Imbangela yalesi simo kukhethwe ngokungafanele ubukhulu befenisha, okuthinta ngqo ukusebenza kalula, ukuma komzimba nempilo emuva. Yingakho, uma udinga ukuthenga ideski, ubukhulu bomkhiqizo buyinto yokuqala okufanele icatshangelwe lapho ukhetha. Ububanzi bemikhiqizo buyahlukahluka ebangeni elibanzi, kusukela ekulungiselelweni okuhlangene kukanxande kuya kumamodeli we-transformer noma izakhiwo zekhoneni. Okokuqala, kufanelekile ukugxila ekukhuleni komsebenzisi, ubukhona bezinkomba ezithile zezokwelapha, ubukhulu begumbi lapho kuhlelwe khona ukubeka itafula, bese kuphela kuzici zangaphakathi nokuthanda komuntu siqu.

Ukusebenza nobukhulu bamadeski

Isimo esibalulekile esithinta usayizi wedeski ukusebenza kwaso. Uma ukumiswa okujwayelekile kwanele kumfundi osemncane, khona-ke indawo yokusebenza yomfundi, umakhi wezakhiwo noma umsebenzi wasehhovisi kufanele ibe nkulu kakhulu. Vele, ubukhulu begumbi lapho ifenisha ehlelelwe ukulethwa nakho kuyabhekwa. Uma leli kuyigumbi elincane, inketho engcono kakhulu kungaba ukufaka ideski lesikole elincane. Amamodeli anjalo ahlukaniswe:

Ikholamu eyodwa. Lona ngumklamo ojwayelekile kakhulu futhi umakethwa ube mncane. Ngakolunye uhlangothi kunendawo yokusebenza, kolunye kunekhabethe elakhelwe ngaphakathi elinamadrowa owodwa noma amaningi. Osayizi abajwayelekile bangu-120 x 60 cm.
Amabhola amabili. Enye imodeli ehlanganisiwe yakudala, amadrowa atholakala ezinhlangothini zombili zetafula. Ubukhulu obujwayelekile bungu-140 x 60 cm.
Ngesisekelo esigingqikayo. Imodeli ivame ukutholakala emahhovisi, ikhulisa kancane ukusebenza kwefenisha. I-curbstone ingasetshenziswa njengengxenye yetafula noma njengefenisha ehlukile yokuzimela. Osayizi bavame ukufana nozakwabo bollard oyedwa.

Kwezinye izimo, ideski lihlanganiswa nedeski lekhompyutha, elithinta ubukhulu befenisha. Imiklamo esebenzayo engu-L (emincane) iyathandwa, ivulekile, kuyilapho ingenamandla kakhulu, ikuvumela ukuthi ubeke kahle zonke izinto ezidingekayo zesikole, i-PC noma ilaptop. Ububanzi bamatafula anjalo buqala kusuka ku-120-160 cm, ukujula kuphakathi kuka-800-120 cm. Amatafula wokuguqula abuye abhekiswe kufenisha esezingeni eliphakathi nendawo, aphakeme kancane futhi abanzi kunalawo ajwayelekile, kuyilapho enezici eziningi ezengeziwe, ikakhulukazi, ukulungiswa kwe-angle angle ukuphakama kwetafula phezulu. Kulula ukubeka amamodeli anjalo ezindlini ezijwayelekile, lapho yonke imitha eyisikwele ibalulekile.

Inketho engcono kakhulu yomfundi ihedsethi egcwele egcwele itafula elakhelwe ngaphakathi, lapho kungangena khona zonke izinto ezidingekayo zemfundo nezentuthuko, kanye nezinto zasendlini. Kufanele kuqondwe ukuthi ukusebenza nobuningi bemodeli enjalo bulingana ngqo.

Osayizi abajwayelekile

Osayizi abajwayelekile bedeski baklanywa ngokuhlanganyela ngabaklami nabasebenzi kumalabhorethri ocwaningo lwezokwelapha. Lapho kwakhiwa ifenisha, ochwepheshe babheka ukusetshenziswa kalula ne-ergonomics. Futhi, ukunakwa okuningi kwanikezwa izinkomba zezokwelapha. Into esemqoka ababeyilwela abaklami ukuthi lapho kwakusebenza etafuleni kwakungekho i-overvoltage, engaholela ezifweni zomgogodla nokuma kwegazi emzimbeni ngesikhathi sokuhlala isikhathi eside endaweni eyodwa. Ubukhulu obukhulu bedeski lomfundi, okufanele ulinake lapho ukhetha, ubude, ubude, ukujula.

Itafula eliqondile

Ideski eliqondile yiyona ifenisha ejwayelekile kakhulu. Ipharamitha ebaluleke kakhulu ukuphakama. Isisekelo sezibalo ukuphakama komuntu. Ngokwesilinganiso esingu-175 cm kumuntu omdala kanye no-162 cm kowesifazane, ukuphakama kwefenisha kufanele kube cishe amasentimitha angama-75. Lesi yisilinganiso sobukhulu obujwayelekile esisetshenziswa lapho kwenziwa ideski eliqondile. Ubukhulu bale modeli yabantu abadala bungafingqwa etafuleni.

Amapharamitha	Ubukhulu
Ukuphakama	70-80 cm
Ubude	60-120 cm
Ukujula	35-80 cm

Lezi yizinkomba ezijwayelekile abakhiqizi abaningi abanamathela kuzo.

Ideski eliqondile lengane lihlukile ngobude kunelabantu abadala. Kumamodeli wezingane, le parameter iqala kusuka ku-52 cm Ubukhulu obukhethwe kahle buzoqinisekisa ukuthi umfundi uzogcina umhlane wakhe uqonde phakathi nekilasi. Uma kusetshenziswa i-laptop noma ikhompiyutha, isikrini sokuqapha, esinobude obudingekayo befenisha, sizoba sezingeni leso, nakho okungeke kulimaze impilo yakho.

Ububanzi nokujula kukhethiwe kucatshangelwa ukusebenza kwetafula. Uma uhlela ukuyisebenzisela ukubhala kuphela, osayizi abancane bazokwanela. Lapho usebenza nemishini yehhovisi, kufanele unikeze ukukhetha phezulu kwetafula elibanzi.

Ukwenza ifenisha isebenze ngokwengeziwe, yenezelwa ngamadilowa, amashalofu, amashalofu kanye nezakhiwo, ezenzelwe ukugcina izincwadi, izincwadi, izincwadi zokubhalela, ama-albhamu, izimpahla zasehhovisi. Amapharamitha amahle wezesekeli afingqiwe etafuleni.

Amapharamitha	Ubukhulu, cm
Ukuphakama kwamashalofu, ama-rack, izakhiwo eziphezulu	210
Ibanga phakathi kwamashalofu	Okwezincwadi zokufunda - 30, izichazamazwi - 40-50, amafolda, ama-albhamu - 40, ezincwadini zokubhalela - 25
Ukujula kwesheluli	Azikho ngaphezu kwama-30

Imodeli yekona

Leli thebula libhekwa njengelikahle kakhulu futhi livulekile ngenxa yokwakheka nosayizi walo. Amapharamitha aphambili wemodeli ye-angular yabantu abadala ngokusho kwe-GOST:

Amapharamitha	Ubukhulu, cm
Ukuphakama	70-80
Ubude ohlangothini lokuqala	150-170
Ubude besibili besecala	120
Ukujula	50-95

Ukukhiqizwa kwamadeski ezingane ngobude nakho kuqala kusuka kuma-cm 52. Uma ufisa, unga-oda imodeli enezilinganiso ngazinye, kepha le nsizakalo izobiza okungaphezulu kokuthenga umkhiqizo ojwayelekile.

Imvamisa, ideski lasekhoneni lihlanganisa imisebenzi yekhompyutha. Idizayini inokufakwa kwekhibhodi, iyunithi lesistimu kanye nokuqapha. Banikezwa amapharamitha alandelayo:

ishalofu lokukhipha - 10-15 cm ngaphansi kwetafula phezulu, leli lungiselelo lilungele ukuthayipha kukhibhodi;
qapha isengezo - 10-12 cm, esizovumela amehlo ukuthi angakhathali ngenkathi esebenza;
yima uhlelo lweyunithi - 10-15 cm ngaphezulu kwesembozo saphansi, esizokhipha ukushisa ngokweqile.

Ubuhle betafula lasekhoneni ukuthi ligcina isikhala, ngenkathi linezindawo ezimbili ezihlukene: ukusebenza ngekhompyutha namaphepha.

Ukwakhiwa okwandayo

Ezinganeni ezilungiselela isikole, okungcono kakhulu kungaba yitafula elikhulayo, ukuphakama kwalo kungakhuphuka njengoba ingane ikhula. Umkhiqizo onjalo awuyikuvumela kuphela ukuthi ugcine isimo esifanele, kepha futhi uzokonga nesabelomali somndeni, ngoba awudingi ukuthenga amamodeli amaningi phakathi nezifundo zakho.

Ukuphakama kwetafula kuyashintshwa ngokuslayida noma ngezindlela zikagesi. Ungayilungisa futhi ngemilenze enokuma kohlamvu "X". Ubukhulu balo mklamo buyakhonjiswa kuthebula.

Amapharamitha	Ubukhulu
Ukuphakama	46-82 cm
Ubude	70-120 cm
Ukujula	50-95 cm

Isinyathelo esijwayelekile sokushintsha ukuphakama komkhiqizo onjalo ngu-5-6 cm.

Okwezingane ezimbili

Emindenini enezingane ezimbili, kuvame ukuba nenkinga ngendawo ekamelweni lokufaka amadeski amaningana. Ukonga isikhala, ungathenga into ekhethekile. Lo mklamo ubukeka njengetafula elijwayelekile, ngenkathi likhudlwana ngosayizi. Ubude obukhulisiwe buvumela izingane ezimbili ukuthi zenze umsebenzi wesikole ngasikhathi sinye, ukudweba, ukumodela nobunye ubuciko, ngaphandle kokuphazanyisana. Ukuba khona kwamashalofu, amadrowa ongagcina kuwo izimpahla zasehhovisi nezincwadi nakho kuzoba ukuhlanganiswa. Ubukhulu bedeski lababili bungaba kanjena:

Amapharamitha	Ubukhulu, cm
Ukuphakama	Cishe ama-75 cm
Ubude	Kusuka ku-200 cm (okungenani imitha elilodwa enganeni ngayinye)
Ukujula	Kusuka ku-90 cm

Uma kunomehluko omkhulu weminyaka phakathi kwezingane, kuzoba nzima ukukhetha itafula elinjalo. Kulokhu, kunconywa ukuthi unake imodeli nomsebenzi wokulungisa ukuphakama kwendawo ngayinye yokusebenza. Isixazululo esifanelekile kungaba futhi ukuthenga izihlalo ezinokuphakama okuguqukayo kanye ne-footrest.

Ungabunquma kanjani ubude obulungile

Ngaphambi kokukhetha ideski lomfundi, kubalulekile ukutadisha izincomo zochwepheshe:

Lapho ubhala, izinyawo zakho kufanele ziqonde phansi. Kuyadingeka ukuthi bafinyelele ngokuphelele kwisembozo saphansi. Imilenze eyeluliwe ikhombisa ukuphakama okungalungile. Zombili izindololwane kufanele zibe phezu kwetafula. Awukwazi ukubayeka balengise.
Ibanga elisuka phezulu kwetafula liye ezinqeni alikho ngaphezu kwamasentimitha ayi-18. Lokhu ukuphakama okujwayelekile okufanele kulandelwe ngaso sonke isikhathi. Okuhlukile yimiklamo enamadilowa ahlehlekayo, anciphisa kancane lobu bukhulu.
Lapho usebenza kukhompyutha, gcina amehlo akho ngqo phambi kwamehlo. Kulokhu, ikhanda akufanele lithambekele phansi.
Lapho ufunda, kubaluleke kakhulu ukuthi ibanga eliphakathi kwencwadi namehlo lilingane nobude bengalo kusukela ekuhlanganeni kwendololwane kuye ezandleni zomunwe.

Itafula, elikhethwe kahle ngobude, alibandakanyi ukuthuthukiswa kwe-scoliosis nezinye izifo zomgogodla enganeni. Ngesikhathi esifanayo, imingcele yesihlalo sezingane nayo ayibalulekile kangako: lapho uphumule ngemuva, isihlalo akufanele sicindezele ngaphansi kwamadolo. Lapho lezi zimo kuhlangatshezwana nazo, emuva kwengane kuyohlala kuqondile. Imithetho efanayo kufanele ilandelwe ngumuntu omdala.

Izidingo eziyisisekelo zamatafula ezingane zesikole

Ngokwehlukana, kufanele uqaphele izidingo zosayizi wedeski, lapho abafundi bachitha khona isikhathi esiningi, kusukela ebangeni lokuqala kuze kuphele ngeleshumi nanye. Ukukhetha imodeli yokusebenza, umuntu kufanele aqondiswe hhayi kakhulu ngesitayela segumbi njengempilo yengane. Ochwepheshe bathuthukise imingcele eyinhloko yedeski - indinganiso yabafundi:

ububanzi kufanele bube imitha eli-1 noma ngaphezulu;
ukujula - kusuka ku-0.6 m nokuningi;
indawo yokubeka izandla - 50 x 50 cm.

Ukuphakama kwedeski kuncike ekuphakameni komfundi. Le mingcele ingafingqwa etafuleni.

Ukuphakama	Ukuphakama kwetafula
110-115 cm	46 cm
115-130 cm	52 cm
145-160 cm	58 cm
160-174 cm	70 cm
Kusuka ku-175 cm	76 cm

Ukuqondiswa ngamapharamitha acacisiwe lapho uthenga imikhiqizo yefenisha yezingane, ungagwema izinkinga zomgogodla, ezihambisana nje nokulingana okungafanele.

Lapho ukhetha umkhiqizo, kubalulekile ukucabangela ukuthi yi-ergonomic, ezovimbela ukulimala lapho ushaya amakhona acijile. Okulungele umsebenzi kuzoba ngumklamo onetafula elithambekele phezulu, elingeke lisebenzise izitendi zamabhuku. I-engeli enyakazayo kufanele ibe ngama-degree angama-30. Kuyafaneleka futhi ukuthatha ngokungathí sina ukukhetha amashalofu angeziwe namatafula asembhedeni, avame ukufakwa emadeskini. Kufanele zivuleke kalula futhi zingaphazamisi umsebenzi wesikole wengane yakho.

Amathiphu awusizo

Ukuqinisekisa ukuthi amakilasi nganoma yisiphi isikhathi anethezekile futhi angalimazi impilo yengane, abazali kufanele bacabangele amathiphu awusizo wokuthi bangakhetha kanjani ideski elifanele. Isixazululo esifanelekile somfundi kungaba isakhiwo esiguqukayo ("esikhulayo"). Kuyinto elula ngoba ikuvumela ukuthi ulungise ukuphakama ukuphakama kwengane, futhi ushintshe nomthambeka wethebula phezulu. Ukwakhiwa okunjalo kuzobiza i-oda elikhulu kakhulu, kepha kuzohlala iminyaka eminingi.

Lapho ukhetha imodeli ejwayelekile yedeski, ungalungisa ukuphakama kwayo nesihlalo esinesihlalo esikhuphukayo. Enye indlela yokuphuma kulesi simo kungaba yindawo yokubeka izinyawo ekhethekile, ezonciphisa ibanga ukusuka etafuleni letafula kuye phansi. Kuyisakhiwo esincane esenziwe ngepulasitiki noma ngensimbi. Kungamiswa - kufakwe eduze nefenisha, noma iphathekayo. Esimweni sesibili, ingasuswa uma amanye amalungu omndeni esebenza etafuleni, nalapho ingane ikhula. Indawo enjalo ungayimisa ngesitulo esincane.
