의자일체형책상
기술분야
[1] 본발명은의자일체형책상에관한것으로，보다상세하게는하나의 책상에서 착좌,기립자세，스트레칭그리고걷기운동으로자세변경이가능한의자일체형 책상에관한것이다.
배경기술
[2] 일반적으로강의실둥에서사용되는책상과의자는종과횡열의줄을맞추기가 번거롭고또한전체사용공간이커지게될뿐아니라，책상을사용을한후에 책상및의자를별도로정리하여야하는불편함이 있다.따라서,이문제를 해결하기위한것으로공간효율성과함께별도로배열상태점검이필요하지 않도록구성한의자일체형책상이제안되어 있다.
[3] 도 1은종래의의자일체형책상의일예를도시한것으로서，이는
메인프레임 (10)의선단에책상용테이블 (14)이고정설치되고，선단보다낮은 위치의후단에는좌석받이 (12)가고정설치된구조로되어 있다.미설명부호 13은 등받이이고， 15는좌석받이및등받이를고정시키는의자프레임으로서,이러한 구성의 책상의경우상기와같은문제의해결이가능하지만,테이블 (14)과 등받이 (13)사이의간격이 일정하게제작된다면신체조건이다른이용자들이 동일한의자가일체로된책상을사용하기에는불편한점이 있다.예를들면， 신체조건이큰이용자특히 ,복부가뚱뚱한이용자가이용할경우에는
테이블 (14)이몸쪽으로밀착된위치에 있게되고，신체조건이마른이용자가 이용할시에는좌석받이 (12)및등받이 (13)를테이블 (14)측으로이동시켜야 하지만고정된구조를가짐으로써조절하여사용하는것이불가능하다.
[4] 이와같이강의실등에서 일반적으로사용되는책상과의자는사용자의몸에 의자의크기를맞추기가번거롭고，특히장시간사용시복부비만및하체피로도 증가등의문제를일으킬수있어사용자신체에악영향을끼친다.아울러，도 1과같은책상의경우장시간착석에따른자세변경,예를들면일어선자세로 학습한다거나업무를보는것은사실상불가능하다.
[5] 따라서，이러한문제를개선하기위해착좌또는기립자세로의자유로운
변경과스트레칭및걷기운동기능을통해복부비만을예방하고하체근력을 강화할수있으며,아을러공간효율성도높은의자일체형 책상의개발이 절실히요구되고있다.
발명의상세한설명
기술적과제

과제해결수단
[7] 위와같은목적을달성하기위한본발명의한형태에따르면，책상부，의자부, 및상기 책상부와의자부의하단을연결하고지지하는바닥부를포함하고,상기 의자부는시트와등받이，그리고상기시트및등받이를지지하는
지지프레임으로구성되며 ,상기시트와등받이는착좌,기립또는스트레칭 자세로의 변경이자유롭도록상기지지프레임상에회전가능하게결합된 것으로서,상기책상부는상판과이상판을지지하는책상다리로이루어져상기 상판에연결된책상다리의상부가상기바닥부에연결된책상다리의
하부로부터인출되어연장가능하게구성되고，상기의자부는시트와등받이， 그리고상기시트및등받이를지지하는지지프레임으로구성되고，상기 지지프레임은바닥으로부터수직의하부프레임과바닥에수평인
상부프레임으로구성되어상기하부프레임상에시트가회전가능하게결합되고 상기상부프레임상에등받이가회전가능하게결합되며，상기상부프레임은 길이방향으로다수의걸림홈들이형성되어 이들걸림홈중어느하나에상기 등받이를옮겨거치할수있도록구성한것올특징으로하는의자일체형책상이 제안된다.
[8] 본발명의 일실시형태로서 ,의자부는책상부로부터 일정거리를유지할수 있도록의자받침에의해상기바닥부상에이동가능하게결합되고，상기 의자받침과지지프레임은의자부의높이조절과소정의쿠션기능을제공하는 신축실린더에의해연결될수있다.본발명의다른실시형태로서，
지지프레임은하부프레임의하부가바닥부에대하여 일정각도의하방으로 연장되어상기바닥부로부터 일정각도의상방향으로연장되는지지프레임 본체에인출가능하게삽입된구조를가지며,상기하부프레임의하부와상기 지지프레임본체의 대응표면은각각다수의나사체결부를갖추어의자부높이 조절에따른체결고정이가능하도록구성할수있다.
[9] 본발명에따르면，책상부는책상다리의양단사이에사용자의발을올려놓을 수있는발받침대가하나이상형성되고，상기발받침대는착좌상태에서발을 올려놓기위한상부발받침대와기립상태에서발을올려놓을수있는하부발 받침대로구성되며,상기상부발받침대와하부발받침대는의자부를향하여 각각상이한기울기를갖는것이바람직하다.
[10] 본발명에따르면，책상부는사용자의착좌또는기립상태에서걷기운동또는 다리운동이가능한스템퍼장치를포함할수있으며，이러한스랩퍼장치는 2개의발판과이발판들의하부를각각지지하는 2개의가스실린더를포함하고, 상기발판은책상다리의양단을연결하는고정바상에회전가능하게결합되며, 상기가스실린더는하단이바닥부의앞단에회전가능하게결합되고상단이 발판의하단에회전가능하게결합된것이제공될수있다.

하부프레임 (21a)에힌지된시트 (22)가책상상판 (11)거의수평을이루고 상부프레임 (21b)에힌지된등받이가책상상판 (U)과거의수직을이룬다.이 상태에서사용자의발은상부발받침대 (14)에올려진상태로편안하게사용할 수있다.
[27] 또한，도 3b에도시된바와같이기립상태에서는사용자의몸을의자부 (20)에 기댄상태로사용할수있는데，이때지지프레임 (21)의하부프레임 (21a)에 힌지된의자의시트 (22)는사용자의다리가향하는방향으로소정의기울어진 각도를유지할수있으며,이상태에서사용자의발은하부발받침대 ( 14)에 올려진상태로몸의하중을지탱할수있다.
[28] 도 4는도 2에따른의자일체형 책상의한변형형태를보여주는측면도로서, 이는하나의책상부 (10)를중심으로그대응하는방향의양쪽에 2개의
의자부 (20)(20')를서로마주보도록배치한구조이다.이와같은구성은하나의 책상에두사람이마주앉아서학습 (study)하거나교습 (teaching)이가능하도록한 것으로,이배치에서책상부 (10)는바닥부 (30')의중앙에고정되고,각각의 의자부 (20)(20')는책상부 (10)를중심으로바닥부 (30')의양쪽에 전후방향으로 이동배치가가능하도록설치될수있으며，책상부 (10)와각의자부 (20)(20')의 구조는도 2에도시된구조와실질적으로동일하다.
[29]
[30] 도 5는도 2에따른의자일체형책상의다른변형형태를도시한것으로,도 5a는책상측면도，도 5b는부분확대평면도，도 5c는작동상태도이다.
[31] 도면에따르면,책상부 (10')는사용자의착좌또는기립상태에서걷기운동 또는다리운동이가능하도록하기위해스탭퍼장치 (stepper;40)를구비할수 있다.이러한스랩퍼장치 (40)는 2개의발판 (42a,42b)과이발판들의하부를각각 지지하는 2개의가스실린더 (41)로구성될수있다.
[32] 각각의발판 (42a, 42b)은책상다리 (12)의 양단을연결하는고정바 (43)상에
회전가능하게힌지결합되고，또한각각의가스실린더 (41)는그하단들이 바닥부의앞단에힌지결합되고상단들이발판의하단에각각힌지결합된 형태로제공될수있으며，이를통해발판에가해지는힘에의해가스실린더가 수축할경우와가스실린더가신장할때상호작용이가능하도록구성된다.
[33]
[34] 도 6은본발명에따른의자일체형책상의제 2실시형태를도시한것으로,도 6a는측방향사시도,도 6b는제 1측면상태도，도 6c는제 2측면상태도이다.
[35] 본실시형태에서의자일체형책상은도 1과마찬가지로책상부 (10)，
의자부 (20)，및상기책상부와의자부의하단을연결하고지지하는바닥부 (30)를 포함하고,책상부 (10)는상판 (11)과이를지지하는책상다리 (12)로이루어져 상기책상다리 (12)의하단이바닥부 (30)상에고정되어 있으며，의자부 (20)는 시트 (22)와둥받이 (23)，그리고상기시트및등받이를지지하는소정의절곡된 형태의지지프레임 (21)으로구성되어 있다.본실시형태에서 책상부 (10)는 책상다리 (12)의높이조절에의해상판의높이를사용자에맞게조절할수 있으며.,또한그에대응하여의자부 (20)의높이도지지프레임 (21)의높이조절을 통해시트 (22)의높이를사용자에맞게조절할수있다.
[36] 지지프레임 (21)은책상부 (10)로부터의자부 (20)의거리를조절할수있도록 바닥부 (30)상에이동가능하게결합되며，바닥으로부터수직인
하부프레임 (21a)과바닥에수평인상부프레임 (21b)을포함하고，하부프레임 (21a) 상에는시트 (22)가회전가능하게힌지결합되고상부프레임 (21b)상에는 등받이 (23)가회전가능하게힌지결합된구조를갖는다.또한,하부프레임 (21a)의 하부는바닥부 (30)에대하여 일정각도의하방으로연장되어상기
바닥부 (30)로부터 일정각도의상방향으로연장되는지지프레임본체에 인출가능하게삽입된형태를갖출수있다.따라서,시트 (22)의결합점아래로 연장된하부프레임 (21a)의하부에는일정간격으로다수의나사공 (21al)이 형성되고이들이삽입되는지지프레임본체에도그에대응하는다수의 나사공 (21a2)이형성되어하부프레임 (21a)의하부를인출한후에는볼트등으로 체결하여의자부 (20)의 일정한높이상태를유지할수있게된다ᅳ
