연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. An easy fold layout hunting blind framework structure comprising: two upper supporting frames each further including first supporting bars and second supporting bars, wherein each of said first supporting bars is connected to a front side bar portion, while each of said second supporting bars is connected to a rear side bar portion, each of said first supporting bars and each of said second supporting bars are in connection with each other via a downwardly turning hinged joint control device so as to control said upper supporting frame to develop or fold by turning upwards or downwards respectively about the hinged joint control device, an outer end of said front side bar portion of each first supporting bar is hinged to right and left sides respectively of a front supporting frame, and an outer end of said rear side bar portion of each said second supporting bar is respectively hinged to right and left sides of a rear supporting frame;the front supporting frame having two side bars, each respectively connected to an opposing side of an upper bar and to a respective one of two bottom bars, wherein a first hinged casing is provided at both right and left sides of said front supporting frame's upper bar so as to be hinged to the outer ends of said front side bar portion of each first supporting bar of said two upper supporting frames via a first shaft hinge, a set base is respectively provided at an upper part of both side bars of said front supporting frame so as to make a hinge connection with a front sustention stand, said bottom bars provided at two sides of said front supporting frame are able to stand on the ground;the rear supporting frame having two side bars, each respectively connected to an opposing side of an upper bar and to a respective one of two bottom bars, wherein a second hinged casing is provided at both right and left sides of said rear supporting frame's upper bar so as to be hinged to the outer ends of said rear side bar portion of each second supporting bar of said two upper supporting frames via a second shaft hinge, said bottom bars provided at two sides of said rear supporting frame are able to stand on the ground, and hinge inner ends with inner ends of said bottom bars provided at two sides of said front supporting frame together with a third shaft hinge;said front sustention stand including two side bars and two bottom bars which are connected to lower parts of said two side bars, wherein upper parts of said front sustention stand's two side bars are respectively hinged to the set bases provided to two sides of said front supporting frame via a fourth shaft hinge, and at the upper parts of said two side bars are respectively provided positioning devices so as to be separably in connection with said two set bases located at two sides of said front supporting frame, said bottom bars of said rear sustention stand are used to stand on the ground. 2. An easy hold layout hunting blind framework structure of claim 1, wherein the upper part of each of said front sustention stand's two side bars is formed into a hollow tube portion and there are a first spring and a corresponding slide slot for settling said positioning device, said hollow tube portion further has a set member such that one end of said first spring butts against said set member, and the other end thereof butts against a middle portion of said positioning device, two opposing ends of said positioning device respectively go through said slide slot to allow said positioning device to compress said first spring and slide up and down in said slide slot, the set bases which are respectively provided on said front supporting frame's two side bars respectively have several positioning slots disposed in different angles such that said positioning devices provided at two side bars of said front sustention stand are free to select any one of said positioning slots between the two set bases provided to said front supporting frame to detain the opposing ends of the positioning device. 3. An easy fold layout hunting blind framework structure of claim 2, wherein said two set bases of said front supporting frame further have a folding detention slot such that said positioning devices provided on said front sustention stand's two side bars are selectable to be confined in said folding detention slot of said two set bases. 4. An easy fold layout hunting blind framework structure of claim 1, wherein each said downwardly turning hinged joint control device provided to said first and said second supporting bars in connection with said upper supporting frame comprises: a joint moving member which has a press button section at one side, and several joint moving detention pawls at the other side, each joint moving detention pawl goes through a corresponding first turning base, and then butts against an end surface of a detention gear;said first turning base has a disc shaped member and coupling nipple connected with the disc shaped member, said disc shaped member is hinged to a second turning base with a hinge member, wherein said coupling nipple of said first turning base is used to joint with said first supporting bar of said upper supporting frame, several via holes are provided on said disc shaped member so as to allow the joint moving detention pawls of said joint moving member to pass through, a center shaft is provided to the other side of said disc shaped member together with several tooth slots;said detention gear has several gear teeth, one side of each gear tooth is meshable with a corresponding tooth slot of said first turning base, said detention gear has a shaft bushing for said center shaft of said first turning base's disc shaped member to be hinged, an annular recess is formed at the other side of said detention gear for accepting one end of a second spring to stretch into and butt against the inner wall of said annular recess;said second spring butts against the inner wall of said detention gear's annular recess with one side, and against said disc shaped member of said second turning base with an opposite side;said second turning base has a disc shaped member and a coupling nipple connected with the former, said coupling nipple is used for connecting with one end of said upper supporting frame's second supporting bar, while said disc shaped member is provided with several tooth slots to allow an opposite side of each gear tooth of the detention gear to mate with.
