Description

간이침대Rollaway bed

본 발명은 간이침대에 관한 것으로서, 더욱 상세하게는 연결바에 회전 가능하게 설치된 회전형 폴수용부에 수평폴을 삽입 체결하여, 수평폴의 중심 위치가 회전형 폴수용부의 회전 중심축 보다 상대적으로 더 낮은 높이상에 위치되도록 함으로써, 침대시트의 텐션에 의해 수평폴이 회전형 폴수용부를 연결바를 향해 하향경사진 방향으로 잡아당겨, 회전형 폴수용부의 고정 상태를 유지시키는 간이침대에 관한 것이다.The present invention relates to a portable bed, and more particularly, to a portable bed in which a horizontal pole is inserted and connected into a rotary pole receiving portion rotatably installed on a connecting bar, such that the center position of the horizontal pole is positioned at a relatively lower height than the center axis of rotation of the rotary pole receiving portion, thereby causing the horizontal pole to pull the rotary pole receiving portion in a downwardly inclined direction toward the connecting bar by the tension of a bed sheet, thereby maintaining the fixed state of the rotary pole receiving portion.

일반적으로, 간이침대는 일반적으로 항시 펼쳐진 상태로 특정 장소에 고정되어 있는 침대보다 가벼운 무게로 제작되거나, 접철이 가능한 구조로 이루어져 휴대성까지 보장되면서 공간을 절약하고 사용상이 편의성을 증가한 상태로 출시되고 있다.In general, a portable bed is manufactured to be lighter than a bed that is usually always fixed to a specific location in an unfolded state, or it is designed to be foldable to ensure portability while saving space and increasing convenience.

특히, 국내에 판매되고 있는 기성품을 참조하면, 이러한 간이침대는 주로 접이식, 텐트식, 조립식과 같이 다양한 구조를 가지고 있는 상태임을 확인할 수 있다.In particular, if we look at the finished products sold domestically, we can see that these portable beds mainly have various structures such as folding, tent-type, and assembly-type.

특허문헌 1(KR 10-1381295 B1)은 종래의 간이침대를 나타낸 것으로서, 이를 참조하면, 양단에 서로 대칭되는 수평폴이 끼워진 천과, 지면에 밀착되어 하중을 지지하는 복수개의 지지바와, 지지바 양단에 설치되어, 수평폴이 체결되도록 허용하는 클립과, 하나 이상의 연결바에 회전축을 중심으로 회전하도록 설치되어, 클립을 정해진 각도 회전시키거나 혹은 클립의 위치를 고정하는 조정부재로 구성된다.Patent Document 1 (KR 10-1381295 B1) shows a conventional folding bed, and with reference thereto, the folding bed is composed of a fabric having horizontal poles symmetrically inserted at both ends, a plurality of support bars that are in close contact with the ground and support a load, clips that are installed at both ends of the support bars and allow the horizontal poles to be fastened, and an adjusting member that is installed to rotate around a rotation axis on one or more connecting bars and rotates the clip by a set angle or fixes the position of the clip.

여기서, 연결바에 설치된 고정 설치된 클립에 천의 수평폴을 걸어 고정하되, 클립에 고정된 수평폴과 반대되는 천의 수평폴을 클립조정부재의 클립에 삽입 체결되도록 한 상태에서, 회전축을 축으로 클립조정부재를 회전시킨다.Here, the horizontal pole of the fabric is hung and fixed on a fixed clip installed on the connecting bar, and the horizontal pole of the fabric opposite to the horizontal pole fixed to the clip is inserted and fixed into the clip of the clip adjustment member, and the clip adjustment member is rotated about the rotation axis.

그러면, 클립조정부재에 의해 클립이 회전되면서 수평폴을 서로 마주보는 반대방향으로 당기게 되고, 이때, 천이 수평폴에 의해 당겨지면서 펼쳐지는 것이다.Then, as the clip is rotated by the clip adjustment mechanism, the horizontal poles are pulled in opposite directions, and at this time, the fabric is pulled by the horizontal poles and spread out.

그리고, 연속하여 클립조정부재를 회전축을 축으로 회전시켜, 클립조정부재가 연결바 외면에 도달하면, 클립조정부재가 연결바 외면에 밀착 체결되면서, 이 클립조정부재에 의해 클립의 위치가 고정되고, 이에따라, 천이 수평폴에 의해 당겨져 펼쳐진 상태를 유지하는 것이다.And, by continuously rotating the clip adjusting member about the rotation axis, when the clip adjusting member reaches the outer surface of the connecting bar, the clip adjusting member is tightly fixed to the outer surface of the connecting bar, and the position of the clip is fixed by the clip adjusting member, and accordingly, the cloth is pulled by the horizontal pole and maintained in an unfolded state.

하지만, 상기와 같은 특허문헌 1은, 클립조정부재를 연결바 외면에 밀착되도록 회전시켜, 이 클립조정부재가 연결바 외면에 체결되도록 강제해야 하고, 노약자 또는 어린이와 같이 상대적으로 체력이 약한 사용자가 클립조정부재를 조작하는 경우, 클립조정부재를 연결바로 부터 잠금 해제하는데 큰 어려움이 있으며, 또한, 연결바에 클립조정부재의 잠금 체결을 위한 별도의 체결구멍 형성으로, 연결바의 강도 저하와 동시에 휨 현상이 발생되고, 클립조정부재의 잠금 및 해제를 반복 조작함에 따라 제품 손상으로 인해 기능이 상실될 우려가 있으며, 잠금 체결을 위한 클립조정부재의 복잡한 구조로, 제작 단가 증가 및 제작에 어려움이 있다.However, the above-mentioned Patent Document 1 requires that the clip adjusting member be rotated so as to be in close contact with the outer surface of the connecting bar, thereby forcing the clip adjusting member to be fastened to the outer surface of the connecting bar. In the case where a user with relatively weak physical strength, such as the elderly or children, operates the clip adjusting member, it is very difficult to unlock the clip adjusting member from the connecting bar. In addition, since a separate fastening hole is formed in the connecting bar for locking and fastening the clip adjusting member, the strength of the connecting bar is reduced and a bending phenomenon occurs at the same time. In addition, there is a concern that the product may be damaged and its function may be lost due to repeated locking and unlocking of the clip adjusting member. In addition, the complex structure of the clip adjusting member for locking and fastening increases the manufacturing cost and makes manufacturing difficult.

상기 회전형 폴수용부(211)는 수평폴(101)의 중심이 상기 회전형 폴수용부(211)의 회전 중심축 보다 상대적으로 낮은 높이에 위치되는 순간 상기 침대시트(100)의 텐션에 의해 서로 마주보는 방향으로 당겨지는 상기 수평폴(101)에 의해 상기 회전형 폴수용부(211)의 회전 중심축을 기준으로 하향 경사진 방향으로 강제 회전되어 상기 연결바(230)에 밀착 고정된다.The above-mentioned rotary pole receiving part (211) is forcibly rotated in a downwardly inclined direction based on the rotational center axis of the rotary pole receiving part (211) by the horizontal pole (101) which is pulled in a direction facing each other by the tension of the bed sheet (100) at the moment when the center of the horizontal pole (101) is positioned at a relatively lower height than the rotational center axis of the rotary pole receiving part (211) and is closely fixed to the connecting bar (230).

상기 회전형 폴수용부(211)는 상기 연결바(230) 외주면을 감싸도록 밀착 고정된 상태에서, 상기 침대시트(100)의 텐션에 의해 서로 마주보는 방향으로 당겨지는 상기 수평폴(101)이 걸림되도록 하여, 상기 수평폴(101)이 서로 마주보는 방향으로 이동하는 것을 제한한다.The above-mentioned rotary pole receiving part (211) is tightly fixed to wrap around the outer surface of the above-mentioned connecting bar (230), and the horizontal pole (101) is pulled in a direction facing each other by the tension of the above-mentioned bed sheet (100), thereby restricting the horizontal pole (101) from moving in a direction facing each other.

상기 회전형 폴수용부(211)는 상기 연결바(230) 말단부에 회전가능하게 설치되어, 상기 연결바(230) 외면을 감싸도록 회전 밀착되는 회전바(211a)와, 상기 회전바(211a) 말단부에서 연장 형성되고, 외면에 외측방향을 향하도록 개구되어 그 내측에 수평폴(101)이 삽입되도록 허용하는 체결홈(211b-1)을 형성하며, 상기 회전바(211a)에 의해 회전되어 상기 수평폴(101)이 서로 마주보는 반대 방향으로 벌어지도록 강제하는 몸체(211b) 및 상기 회전바(211a) 및 연결바(230)를 관통하도록 체결되되, 상기 체결홈(211b-1)에 삽입된 상기 수평폴(101)의 중심축 높이보다 상대적으로 더 높게 형성되어, 상기 회전바(211a)의 회전을 지지하는 힌지축(211c)으로 구성된다.The above-described rotary pole receiving portion (211) is configured with a rotary bar (211a) that is rotatably installed at the end of the connecting bar (230) and is rotatably attached to surround the outer surface of the connecting bar (230), a body (211b) that extends from the end of the rotary bar (211a) and forms a fastening groove (211b-1) that is opened on the outer surface to face outward and allows a horizontal pole (101) to be inserted into the inside thereof, and is rotated by the rotary bar (211a) to force the horizontal pole (101) to spread in opposite directions so that they face each other, and a hinge shaft (211c) that is fastened so as to penetrate the rotary bar (211a) and the connecting bar (230), but is formed relatively higher than the height of the central axis of the horizontal pole (101) inserted into the fastening groove (211b-1) to support the rotation of the rotary bar (211a).

상기 회전바(211a)는 상기 힌지축(211c)을 축으로 회전되어, 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심 방향 또는 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되도록 강제한다.The above-mentioned rotary bar (211a) rotates about the hinge axis (211c) to force the body (211b) to rotate toward the center between the pole receiving portions (210) or in a direction opposite to the center between the pole receiving portions (210).

상기 회전바(211a)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향을 향하도록 회전시켜, 상기 몸체(211b)의 체결홈(211b-1)에 상기 수평폴(101)이 삽입 체결되도록 하고, 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전시켜, 상기 수평폴(101)이 서로 마주보는 반대 방향으로 벌어지도록 강제한다.The above-mentioned rotating bar (211a) rotates the body (211b) toward the center between the pole receiving portions (210), so that the horizontal pole (101) is inserted and fastened into the fastening groove (211b-1) of the body (211b), and rotates the body (211b) in a direction opposite to the center between the pole receiving portions (210), so that the horizontal poles (101) are forced to spread in opposite directions facing each other.

상기 회전바(211a)는 사용자의 조작에 의해 상기 힌지축(211c)을 축으로 회전되는 것이 바람직하다.It is preferable that the above-mentioned rotating bar (211a) rotates about the hinge axis (211c) by the user's operation.

상기 회전바(211a)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전시키되, 상기 연결바(230) 외면에 밀착되어, 상기 몸체(211b)가 정해진 각도 이상 회전되는 것을 제한한다.The above-mentioned rotation bar (211a) rotates the body (211b) in a direction opposite to the center between the pole receiving portions (210), but is in close contact with the outer surface of the connecting bar (230) to limit the body (211b) from rotating beyond a predetermined angle.

상기 몸체(211b)는 반원, 타원, 곡면 또는 다각형상중 어느 하나의 형상으로 형성되어, 그 내부에 상기 수평폴(101)이 삽입 걸림되도록 한다.The above body (211b) is formed in any one of a semicircle, an ellipse, a curved surface or a polygonal shape, so that the horizontal pole (101) is inserted and caught inside it.

상기 몸체(211b)는 상기 회전바(211a)에 의해 정방향 또는 역방향으로 회전되어, 상기 체결홈(211b-1)에 상기 수평폴(101)이 걸림되도록 하거나 혹은 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제한다.The above body (211b) is rotated forward or backward by the above rotation bar (211a) to cause the horizontal pole (101) to be caught in the above fastening groove (211b-1) or to force the horizontal pole (101) to spread in opposite directions facing each other.

상기 몸체(211b)는 상기 회전바(211a)에 의해 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되어, 상기 체결홈(211b-1)에 삽입 체결된 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮게 위치되도록 한다.The above body (211b) is rotated in a direction opposite to the center between the pole receiving portions (210) by the above rotation bar (211a), so that the center of the horizontal pole (101) inserted and connected into the above fastening groove (211b-1) is positioned relatively lower than the height of the hinge axis (211c).

상기 몸체(211b)는 상기 침대시트(100)의 텐션에 의해 상기 폴수용부(210) 사이의 중심 방향으로 당겨지는 수평폴(101)에 반발력을 부여하여, 상기 회전바(211a)가 상기 힌지축(211c)을 축으로 하향경사진 방향으로 회전되어 상기 연결바(230) 외면에 밀착 고정되도록 강제한다.The above body (211b) provides a repulsive force to the horizontal pole (101) that is pulled toward the center between the pole receiving portions (210) by the tension of the bed sheet (100), thereby forcing the rotation bar (211a) to rotate in a downwardly inclined direction about the hinge axis (211c) and be fixed in close contact with the outer surface of the connection bar (230).

상기 몸체(211b)는 상기 체결홈(211b-1)을 반원, 타원, 곡면 또는 다각형상중 어느 하나의 형상으로 형성되어, 그 내부에 상기 수평폴(101)이 삽입 걸림되도록 한다.The above body (211b) is formed with the above fastening groove (211b-1) in any one of a semicircle, an ellipse, a curved surface or a polygonal shape, so that the horizontal pole (101) is inserted and caught inside it.

상기 몸체(211b)는 상기 몸체(211b) 말단부에서 곡면 구조를 갖도록 굴곡지게 연장 형성되어, 상기 수평폴(101)이 상기 체결홈(211b-1) 방향으로 진입되도록 안내하는 안내곡면부(211b-2)를 더 형성한다.The above body (211b) is formed to extend in a curved manner at the end of the body (211b) to have a curved structure, thereby further forming a guide curved portion (211b-2) that guides the horizontal pole (101) to enter in the direction of the fastening groove (211b-1).

상기 안내곡면부(211b-2)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전 작동시, 상기 수평폴(101)이 상기 체결홈(211b-1) 방향으로 진입되도록 안내한다.The above guide curved surface (211b-2) guides the horizontal pole (101) to enter toward the fastening groove (211b-1) when the body (211b) is rotated in a direction opposite to the center between the pole receiving portions (210).

상기 폴수용부(210)은 상기 회전형 폴수용부(211)과 반대되는 상기 연결바(230) 말단부에 고정 설치되고, 외측 방향을 향하도록 개구되어 상기 수평폴(101)이 삽입 고정되도록 하는 고정형 폴수용부(212)를 더 형성한다.The above pole receiving portion (210) is fixedly installed at the end of the connecting bar (230) opposite to the above rotating pole receiving portion (211), and further forms a fixed pole receiving portion (212) that is opened toward the outside so that the horizontal pole (101) can be inserted and fixed.

상기 고정형 폴수용부(212)는 상기 연결바(230) 말단부에 고정 설치된 상태에서, 상기 침대시트(100)의 수평폴(101)이 걸림 고정된 상태를 유지하도록 한다.The above fixed pole receiving portion (212) is fixedly installed at the end of the connecting bar (230) so that the horizontal pole (101) of the bed sheet (100) is maintained in a hung and fixed state.

상기 고정형 폴수용부(212)는 상기 회전형 폴수용부(211)에 의해 상기 수평폴(101)이 서로 마주보는 방향으로 당겨지는 동안 상기 수평폴(101)이 걸림 고정되도록 상기 수평폴(101)에 반발력을 부여하여, 상기 수평폴(101)이 상기 폴수용부(210) 사이의 중심 방향으로 이동하는 것을 제한한다.The fixed pole receiving portion (212) above applies a repulsive force to the horizontal pole (101) so that the horizontal pole (101) is fixedly caught while the horizontal pole (101) is pulled in a direction facing each other by the rotating pole receiving portion (211), thereby restricting the horizontal pole (101) from moving toward the center between the pole receiving portions (210).

상기와 같이 구성되는 본 발명의 제1실시예에 따른 간이침대는 다음과 같이 사용된다.The portable bed according to the first embodiment of the present invention configured as described above is used as follows.

본 발명에 따른 간이침대는 서로 대칭 형상을 이루는 상기 연결바(230) 말단부 각각에 폴수용부(210)의 회전형 폴수용부(211)를 연결하거나 혹은 회전형 폴수용부(211) 및 고정형 폴수용부(212)를 연결할 수 있으나, 이하에서는, 상기 연결바(230) 말단부 각각에 회전형 폴수용부(211) 및 고정형 폴수용부(212)를 연결한 것을 예로 들어 설명하도록 한다.The portable bed according to the present invention can connect a rotating pole receiving portion (211) of a pole receiving portion (210) to each end of the connecting bars (230) that form a symmetrical shape, or can connect a rotating pole receiving portion (211) and a fixed pole receiving portion (212). However, below, an example in which a rotating pole receiving portion (211) and a fixed pole receiving portion (212) are connected to each end of the connecting bars (230) will be described.

먼저, 수평폴(101)이 끼워진 침대시트(100)를 구비하고, 그 상태에서 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제하여, 상기 수평폴(101) 사이를 연결하는 침대시트(100)가 펼쳐지도록 한다.First, a bed sheet (100) with horizontal poles (101) inserted is provided, and in that state, the horizontal poles (101) are forced to spread in opposite directions so that the bed sheet (100) connecting the horizontal poles (101) is spread out.

이때, 상기 수평폴(101)은 상기 침대시트(100)의 양단에 끼워진 상태로 휴대되거나 혹은 상기 침대시트(101)에서 분리된 상태로 휴대되어, 사용시 상기 침대시트(100)의 양단에 끼워서 사용할 수 있다.At this time, the horizontal pole (101) can be carried in a state where it is inserted into both ends of the bed sheet (100) or carried in a state where it is separated from the bed sheet (101) and used by inserting it into both ends of the bed sheet (100).

그리고, 텐션유지부(200)의 지지바(220) 양단에 연결몰드(240)를 끼움 고정하되, 그 상태에서 상기 연결몰드(240)에 연결바(230)를 연결 고정하여, 상기 연결몰드(240)에 의해 상기 지지바(220)와 상기 연결바(230)이 연결되도록 한다.Then, a connecting mold (240) is fitted and fixed to both ends of the support bar (220) of the tension maintenance unit (200), and in that state, a connecting bar (230) is connected and fixed to the connecting mold (240), so that the supporting bar (220) and the connecting bar (230) are connected by the connecting mold (240).

여기서, 상기 연결바(230)는 상기 연결몰드(240)에 끼움 고정되어, 상기 지지바(220) 양단에 상광하협구조를 이루도록 정해진 각도 경사지게 형성된 상태에서, 그 말단부에 폴수용부(210)를 형성한 것이다.Here, the connecting bar (230) is fixedly fitted into the connecting mold (240) and formed at a predetermined angle to form a light-light-lowering structure at both ends of the supporting bar (220), and a pole receiving portion (210) is formed at the end thereof.

이때, 상기 연결바(230) 중 어느 하나의 말단부에는 고정형 폴수용부(212)가 고정 설치된 상태를 유지하고, 상기 고정형 폴수용부(212)와 반대되는 상기 연결바(230)의 말단부에는 회전형 폴수용부(211)가 회전 가능하게 설치된 것이다.At this time, a fixed pole receiving portion (212) is maintained in a fixed state at the end of one of the connecting bars (230), and a rotatable pole receiving portion (211) is installed so as to be rotatable at the end of the connecting bar (230) opposite to the fixed pole receiving portion (212).

이후, 상기 고정형 폴수용부(211)에 상기 침대시트(100)의 수평폴(101)을 삽입 체결하고, 그 상태에서 상기 회전형 폴수용부(211)의 회전바(211a)를 회전시켜, 상기 회전바(211a) 말단부에 연장 형성된 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심 방향을 향하도록 회전시킨다.Thereafter, the horizontal pole (101) of the bed sheet (100) is inserted and fixed into the fixed pole receiving portion (211), and in that state, the rotating bar (211a) of the rotating pole receiving portion (211) is rotated so that the body (211b) extended from the end of the rotating bar (211a) rotates toward the center between the pole receiving portions (210).

그리고, 상기 고정형 폴수용부(211)에 삽입 체결된 수평폴(101)과 반대되는 상기 침대시트(100)의 수평폴(101)을 상기 몸체(211b)의 체결홈(211b-1)으로 진입시키고, 그 상태에서 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되도록 상기 회전바(211a)를 강제 회전시킨다.Then, the horizontal pole (101) of the bed sheet (100), which is opposite to the horizontal pole (101) inserted and connected to the fixed pole receiving portion (211), is introduced into the connecting groove (211b-1) of the body (211b), and in that state, the rotating bar (211a) is forcibly rotated so that the body (211b) rotates in the opposite direction to the center between the pole receiving portions (210).

이때, 상기 회전바(211a)를 회전시키기 이전 시점에서는 상기 체결홈(211b-1)에 삽입된 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 더 높게 위치된다.At this time, before rotating the rotating bar (211a), the center of the horizontal pole (101) inserted into the fastening groove (211b-1) is positioned relatively higher than the height of the hinge axis (211c).

여기서, 상기 회전바(211a)를 상기 힌지축(211c)을 기준으로 회전시키면, 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되고, 이때, 상기 몸체(211b)에 삽입 체결된 상기 수평폴(101)이 상기 안내곡면부(211b-2)를 따라 미끄러져 상기 체결홈(211b-1)으로 진입된다.Here, when the rotating bar (211a) is rotated based on the hinge axis (211c), the body (211b) is rotated in a direction opposite to the center between the pole receiving portions (210), and at this time, the horizontal pole (101) inserted and connected to the body (211b) slides along the guide curved portion (211b-2) and enters the connecting groove (211b-1).

여기서, 상기 체결홈(211b-1) 내에 삽입 체결된 수평폴(101)은 상기 몸체(211b)에 의해 서로 마주보는 반대 방향으로 벌어지면서 상기 침대시트(100)를 펼치고, 상기 회전바(211a)에 의해 연속 회전되어 그 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮은 높이에 위치된다.Here, the horizontal pole (101) inserted and fastened within the fastening groove (211b-1) is spread in opposite directions facing each other by the body (211b) to unfold the bed sheet (100), and is continuously rotated by the rotating bar (211a) so that its center is positioned at a height relatively lower than the height of the hinge axis (211c).

이때, 상기 수평폴(101)의 중심은 단면이 보이도록 절단된 상태에서의 중심을 일컫는 것이다.At this time, the center of the horizontal pole (101) refers to the center when the cross-section is cut so that it is visible.

그리고, 상기 수평폴(101)의 중심 높이가 상기 힌지축(211c)의 높이보다 상대적으로 낮은 높이에 위치되면, 상기 침대시트(100)의 텐션에 의해 상기 수평폴(101)이 상기 폴수용부(210) 사이의 중심 방향으로 당겨지고, 이때, 상기 수평폴(101)이 상기 회전형 폴수용부(211)의 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 당기게 된다.And, when the center height of the horizontal pole (101) is positioned at a relatively lower height than the height of the hinge axis (211c), the horizontal pole (101) is pulled toward the center between the pole receiving portions (210) by the tension of the bed sheet (100), and at this time, the horizontal pole (101) pulls the body (211b) of the rotating pole receiving portion (211) toward the center between the pole receiving portions (210).

그러면, 상기 몸체(211b)의 당김력에 의해 상기 회전바(211a)가 상기 힌지축(211c)을 기준으로 하향 경사진 방향으로 회전되어 상기 연결바(230) 외면에 밀착 고정되고, 이에따라, 상기 몸체(211b)의 회전이 제한된 상태로 상기 수평폴(101)에 반발력을 부여함으로써, 상기 수평폴(101)이 상기 몸체(211b)에 걸림 고정된다.Then, the rotating bar (211a) is rotated in a downwardly inclined direction based on the hinge axis (211c) by the pulling force of the body (211b) and is closely fixed to the outer surface of the connecting bar (230), and accordingly, by applying a repulsive force to the horizontal pole (101) while the rotation of the body (211b) is limited, the horizontal pole (101) is fixed by being hooked to the body (211b).

즉, 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮게 위치된 상태에서, 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 당기게 됨으로써, 상기 회전바(211a)가 상기 힌지축(211c)을 기준으로 하향 경사진 방향으로 강제 회전되면서 상기 연결바(230)에 밀착 고정되어, 상기 회전바(211a)가 고정된다.That is, when the center of the horizontal pole (101) is positioned relatively lower than the height of the hinge axis (211c), the body (211b) is pulled toward the center between the pole receiving portions (210), so that the rotation bar (211a) is forcibly rotated in a downward inclined direction based on the hinge axis (211c) and is tightly fixed to the connecting bar (230), thereby fixing the rotation bar (211a).

이때, 상기 침대시트(100) 양단에 설치된 수평폴(101)은 각각 상기 고정형 폴수용부(212) 및 회전형 폴수용부(211)의 반발력에 의해 서로 이격된 상태를 유지하면서, 상기 수평폴(101)을 서로 마주보는 반대방향으로 당김으로써, 상기 침대시트(100)가 펼쳐진 상태로 유지된다.At this time, the horizontal poles (101) installed at both ends of the bed sheet (100) are kept apart from each other by the repulsive force of the fixed pole receiving portion (212) and the rotating pole receiving portion (211), respectively, and the bed sheet (100) is maintained in an unfolded state by pulling the horizontal poles (101) in opposite directions facing each other.

이후, 상기와 같이 상기 침대시트(100)의 수평폴(100) 길이방향을 따라 상기와 동일한 방법으로 상기 텐션유지부(200)를 복수개 설치하여, 상기 연결몰드(240)의 받침블럭(241)에 형성된 평탄면이 지면에 밀착되도록 함으로써, 상기 침대시트(100)가 지면으로 부터 정해진 높이상에 위치된다.Thereafter, as described above, a plurality of tension maintenance members (200) are installed along the length direction of the horizontal pole (100) of the bed sheet (100) in the same manner as described above, so that the flat surface formed on the support block (241) of the connecting mold (240) is in close contact with the ground, thereby positioning the bed sheet (100) at a predetermined height from the ground.

즉, 상기 회전형 폴수용부(211)를 회전시켜, 상기 침대시트(100)가 펼쳐진 상태를 유지하도록 함으로써, 간이침대의 사용이 가능한 상태로 변화되는 것이다.That is, by rotating the above-mentioned rotary pole receiving portion (211) so that the bed sheet (100) is maintained in an unfolded state, the bed is changed to a state in which it can be used.

한편, 상기 침대시트(100)의 높이를 상승시키고자 하는 경우에는, 상기 연결몰드(240)에 연결다리(242)를 연결하여, 이 연결다리(242) 하단이 지면에 밀착되도록 하면, 상기 연결몰드(240)가 지면으로 부터 정해진 높이상에 위치되고, 이에따라, 상기 연결다리(242) 높이에 비례하도록 상기 침대시트(100)의 높이가 상승되는 것이다.Meanwhile, in case of wanting to increase the height of the bed sheet (100), by connecting a connecting bridge (242) to the connecting mold (240) and making the lower end of the connecting bridge (242) come into close contact with the ground, the connecting mold (240) is positioned at a predetermined height from the ground, and accordingly, the height of the bed sheet (100) is increased in proportion to the height of the connecting bridge (242).

이때, 상기 연결다리(242) 하단에는 미끄럼방지캡(242a)이 설치되어 있고, 이 미끄럼방지캡(242a)이 지면에 밀착되도록 함으로써, 상기 연결다리(242)가 지면으로 부터 미끄러지는 것이 방지된다.At this time, an anti-slip cap (242a) is installed at the bottom of the connecting bridge (242), and by making the anti-slip cap (242a) adhere to the ground, the connecting bridge (242) is prevented from slipping from the ground.

그 다음, 상기 침대시트(100)에 착석하거나 혹은 드러누워 휴식을 취하는 것이다.Next, sit down or lie down on the bed sheet (100) to rest.

[실시예 2][Example 2]

이하의 설명에서, 제1실시예와 동일한 구성에 대해서는 동일한 참조부호를 사용하고 이에 대한 상세한 설명은 생략한다.In the following description, the same reference numerals are used for the same configuration as the first embodiment, and a detailed description thereof is omitted.

도 8 내지 도 9를 참조하면, 텐션유지부(200)는 양단에 상기 수평폴(101)이 삽입 체결되도록 허용하는 복수의 폴수용부(210)를 구비하여, 상기 수평폴(101) 사이를 연결하고, 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제하여, 상기 침대시트(100)가 펼쳐진 상태를 유지하도록 한다.Referring to FIGS. 8 and 9, the tension maintenance unit (200) has a plurality of pole receiving portions (210) that allow the horizontal poles (101) to be inserted and fastened at both ends, thereby connecting the horizontal poles (101) and forcing the horizontal poles (101) to spread in opposite directions facing each other, thereby maintaining the bed sheet (100) in an unfolded state.

상기 텐션유지부(200)는 상기 침대시트(100)의 길이방향을 따라 정해진 간격 이격되게 복수개로 설치되어, 상기 수평폴(101) 사이를 연결한다.The above tension maintenance members (200) are installed in multiple numbers at set intervals along the length direction of the bed sheet (100) and connect between the horizontal poles (101).

상기 텐션유지부(200)는 지면에 밀착되어, 상기 침대시트(100)가 지면에서 정해진 높이에 위치되도록 상기 침대시트(100)를 떠받쳐 지지한다.The above tension maintenance member (200) is in close contact with the ground and supports the bed sheet (100) so that the bed sheet (100) is positioned at a set height from the ground.

상기 텐션유지부(2000는 중앙부가 만곡 형상으로 형성되고, 양측에 회전가능하게 각각 설치되어 지면에 지지되는 보조다리(221)를 형성하며, 상기 침대시트(100)의 길이 방향을 따라 정해진 간격 이격되게 복수개로 형성되어, 상기 침대시트(100)에 가해지는 하중을 지지하는 지지바(220)와, 상기 지지바(220) 양단에서 상광하협 구조를 이루도록 정해진 각도 굴곡지게 일체로 연장 형성되어, 말단부에 상기 폴수용부(210)를 연결한 연결바(230)를 포함한다.The above tension maintenance member (2000) is formed in a curved shape at the center and forms auxiliary legs (221) that are rotatably installed on both sides and are supported on the ground, and includes a plurality of support bars (220) that are formed at a set interval along the length direction of the bed sheet (100) to support the load applied to the bed sheet (100), and a connecting bar (230) that is integrally formed to extend at a set angle to form an upper-lower structure at both ends of the support bar (220) and connects the pole receiving member (210) to the end.

상기 지지바(220)는 상기 침대시트(100)에 가해지는 하중에 의해 양단이 서로 마주보는 반대 방향으로 벌어지면서 완충되어, 상기 침대시트(100)에 가해지는 하중을 지지한다.The above support bar (220) is cushioned by the load applied to the bed sheet (100) by spreading in opposite directions so that both ends face each other, thereby supporting the load applied to the bed sheet (100).

상기 지지바(220)는 중앙부가 지면에 밀착되는 상기 보조다리(221)에 지지되어, 공중에 부양되도록 지면으로 부터 정해진 높이상에 위치되거나 혹은 중앙부가 상기 보조다리(221)와 동시에 지면에 밀착되어 상기 침대시트(100)에 가해지는 하중을 지지한다.The above support bar (220) is supported by the auxiliary leg (221) whose central portion is in close contact with the ground, and is positioned at a predetermined height from the ground so as to float in the air, or the central portion is in close contact with the ground at the same time as the auxiliary leg (221) to support the load applied to the bed sheet (100).

상기 지지바(220)는 중앙부 높이가 상기 보조다리(221) 하단 높이와 동일한 높이로 형성되어 지면에 밀착되거나 혹은 상기 보조다리(221) 하단 높이보다 상대적으로 높게 형성되어 공중에 부양된 상태를 유지한다.The above support bar (220) is formed with a central height equal to the height of the lower end of the auxiliary leg (221) so as to be in close contact with the ground, or is formed relatively higher than the height of the lower end of the auxiliary leg (221) so as to be maintained in a floating state in the air.

상기 보조다리(221)는 만곡 형성된 상기 연결바(230)의 양단 중 어느 한 방향으로 상기 연결바(230)가 기울어지는 것을 방지한다.The above auxiliary leg (221) prevents the connecting bar (230) formed in a curve from tilting in either direction at either end of the connecting bar (230).

상기 보조다리(221)는 상기 연결바(230)와 직교되는 각도를 이루도록 회전되어, 상기 연결바(230) 양단에 가해지는 하중을 지탱한다.The above auxiliary leg (221) is rotated to form an angle perpendicular to the connecting bar (230) and supports the load applied to both ends of the connecting bar (230).

상기 연결바(230)는 만곡 형성된 상기 지지바(220)에서 연장되도록 상기 지지바(220)와 동일 각도로 굴곡지게 형성되는 것이 바람직하다.It is preferable that the above connecting bar (230) be formed to be bent at the same angle as the support bar (220) so as to extend from the curved support bar (220).

상기 연결바(230)는 상기 지지바(220) 양단에 서로 대칭되게 형성된다.The above connecting bars (230) are formed symmetrically at both ends of the above supporting bars (220).

상기 연결바(230)는 상기 지지바(220) 양단에 형성되어, 상기 수평폴(101)이 서로 이격된 상태를 유지하도록 강제하여, 상기 침대시트(100)를 펼쳐진 상태로 유지시킨다.The above connecting bar (230) is formed at both ends of the support bar (220) to force the horizontal poles (101) to remain spaced apart from each other, thereby maintaining the bed sheet (100) in an unfolded state.

상기 연결바(230)는 외면에 회전작동되는 상기 폴수용부(210)의 회전형 폴수용부(211)가 밀착되도록 허용하여, 상기 회전형 폴수용부(211)가 정해진 각도 이상 회전되는 것을 제한한다.The above connecting bar (230) allows the rotating pole receiving portion (211) of the above pole receiving portion (210) that rotates on the outer surface to come into close contact, thereby restricting the rotating pole receiving portion (211) from rotating beyond a predetermined angle.

상기 연결바(230)는 서로 대칭되는 양 말단부에 폴수용부(210)의 회전형 폴수용부(211)가 회전가능하게 설치되도록 허용하거나 혹은 서로 대칭되는 양 말단부에 회전형 폴수용부(211) 및 고정형 폴수용부(212) 각각이 설치되도록 허용한다.The above connecting bar (230) allows the rotational pole receiving portion (211) of the pole receiving portion (210) to be rotatably installed at both ends symmetrical to each other, or allows the rotational pole receiving portion (211) and the fixed pole receiving portion (212) to be installed at both ends symmetrical to each other.

상기 복수의 폴수용부(210) 중 어느 하나 이상은 외측 방향을 향하도록 개구되어 상기 수평폴(101)이 삽입 체결되도록 허용하고, 상기 연결바(230) 중 어느 하나의 말단부를 중심으로 회전 가능하게 설치되며, 사용시 상기 연결바(230) 기준으로 회전되는 상기 폴수용부(210)의 회전 중심축 보다 상대적으로 더 낮은 높이상에 상기 수평폴(101)의 중심이 위치되도록 하여, 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제하는 회전형 폴수용부(211)이다.At least one of the above-described plurality of pole receiving portions (210) is opened toward the outside to allow the horizontal pole (101) to be inserted and connected, and is installed so as to be rotatable around the end of one of the above-described connecting bars (230), and is a rotatable pole receiving portion (211) that forces the horizontal poles (101) to spread in opposite directions so that the center of the horizontal pole (101) is positioned at a relatively lower height than the rotational center axis of the pole receiving portion (210) that rotates around the above-described connecting bar (230) when in use.

상기 회전형 폴수용부(211)는 사용시 상기 연결바(230) 하단부를 감싸도록 밀착되어, 상기 수평폴(101)의 중심이 상기 회전형 폴수용부(211)의 회전 중심축 보다 상대적으로 더 낮은 높이상에 위치되도록 한다.The above-mentioned rotary pole receiving portion (211) is tightly fitted to surround the lower portion of the above-mentioned connecting bar (230) when in use, so that the center of the above-mentioned horizontal pole (101) is positioned at a relatively lower height than the rotational center axis of the above-mentioned rotary pole receiving portion (211).

상기 회전형 폴수용부(211)는 서로 대칭 형성된 연결바(230) 중 어느 하나에 회전가능하게 설치되거나 혹은 연결바(230) 각각에에 회전가능하게 설치될 수 있다.The above-mentioned rotary pole receiving portion (211) may be rotatably installed on one of the connecting bars (230) that are formed symmetrically to each other or may be rotatably installed on each of the connecting bars (230).

상기 회전형 폴수용부(211)는 상기 수평폴(101)이 삽입 체결되도록 하되, 그 상태에서 회전 작동되면서, 상기 수평폴(101)을 서로 마주보는 반대방향으로 벌어지도록 강제하여, 상기 침대시트(100)가 펼쳐진 상태를 유지하도록 한다.The above-mentioned rotary pole receiving part (211) allows the horizontal pole (101) to be inserted and fixed, and while in that state, it rotates to force the horizontal poles (101) to spread in opposite directions so that the bed sheet (100) is maintained in an unfolded state.

상기 회전형 폴수용부(211)는 회전 작동에 의해 상기 수평폴(101)의 중심이 상기 회전형 폴수용부(211)의 회전 중심축 보다 상대적으로 낮은 높이에 위치되는 순간 상기 침대시트(100)의 텐션에 의해 서로 마주보는 방향으로 당겨지는 상기 수평폴(101)에 의해 상기 회전형 폴수용부(211)의 회전 중심축을 기준으로 하향 경사진 방향으로 강제 회전되어 상기 연결바(230)에 밀착 고정된다.The above-mentioned rotary pole receiving portion (211) is forcibly rotated in a downwardly inclined direction based on the rotational center axis of the rotary pole receiving portion (211) by the horizontal pole (101) being pulled in a direction facing each other by the tension of the bed sheet (100) at the moment when the center of the horizontal pole (101) is positioned at a relatively lower height than the rotational center axis of the rotary pole receiving portion (211) by the rotational operation, and is closely fixed to the connecting bar (230).

상기 회전형 폴수용부(211)는 상기 연결바(230) 외주면을 감싸도록 밀착 고정된 상태에서, 상기 침대시트(100)의 텐션에 의해 서로 마주보는 방향으로 당겨지는 상기 수평폴(101)이 걸림되도록 하여, 상기 수평폴(101)이 서로 마주보는 방향으로 이동하는 것을 제한한다.The above-mentioned rotary pole receiving part (211) is tightly fixed to wrap around the outer surface of the above-mentioned connecting bar (230), and the horizontal pole (101) is pulled in a direction facing each other by the tension of the above-mentioned bed sheet (100), thereby restricting the horizontal pole (101) from moving in a direction facing each other.

상기 회전형 폴수용부(211)는 상기 연결바(230) 말단부에 회전가능하게 설치되어, 상기 연결바(230) 외면을 감싸도록 회전 밀착되는 회전바(211a)와, 상기 회전바(211a) 말단부에서 연장 형성되고, 외면에 외측방향을 향하도록 개구되어 그 내측에 수평폴(101)이 삽입되도록 허용하는 체결홈(211b-1)을 형성하며, 상기 회전바(211a)에 의해 회전되어 상기 수평폴(101)이 서로 마주보는 반대 방향으로 벌어지도록 강제하는 몸체(211b) 및 상기 회전바(211a) 및 연결바(230)를 관통하도록 체결되되, 상기 체결홈(211b-1)에 삽입된 상기 수평폴(101)의 중심축 높이보다 상대적으로 더 높게 형성되어, 상기 회전바(211a)의 회전을 지지하는 힌지축(211c)으로 구성된다.The above-described rotary pole receiving portion (211) is configured with a rotary bar (211a) that is rotatably installed at the end of the connecting bar (230) and is rotatably attached to surround the outer surface of the connecting bar (230), a body (211b) that extends from the end of the rotary bar (211a) and forms a fastening groove (211b-1) that is opened on the outer surface to face outward and allows a horizontal pole (101) to be inserted into the inside thereof, and is rotated by the rotary bar (211a) to force the horizontal pole (101) to spread in opposite directions so that they face each other, and a hinge shaft (211c) that is fastened so as to penetrate the rotary bar (211a) and the connecting bar (230), but is formed relatively higher than the height of the central axis of the horizontal pole (101) inserted into the fastening groove (211b-1) to support the rotation of the rotary bar (211a).

상기 회전바(211a)는 상기 힌지축(211c)을 축으로 회전되어, 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심 방향 또는 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되도록 강제한다.The above-mentioned rotary bar (211a) rotates about the hinge axis (211c) to force the body (211b) to rotate toward the center between the pole receiving portions (210) or in a direction opposite to the center between the pole receiving portions (210).

상기 회전바(211a)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 회전시켜, 상기 몸체(211b)의 체결홈(211b-1)에 상기 수평폴(101)이 삽입 체결되도록 하고, 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전시켜, 상기 수평폴(101)이 서로 마주보는 반대 방향으로 벌어지도록 한다.The above-mentioned rotating bar (211a) rotates the body (211b) toward the center between the pole receiving portions (210) so that the horizontal pole (101) is inserted and fixed into the fastening groove (211b-1) of the body (211b), and rotates the body (211b) in a direction opposite to the center between the pole receiving portions (210) so that the horizontal poles (101) are spread in opposite directions facing each other.

상기 회전바(211a)는 사용자의 조작에 의해 상기 힌지축(211c)을 축으로 회전되는 것이 바람직하다.It is preferable that the above-mentioned rotating bar (211a) rotates about the hinge axis (211c) by the user's operation.

상기 회전바(211a)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 회전시키되, 상기 연결바(230) 외면에 밀착되어, 상기 몸체(211b)가 정해진 각도 이상 회전되는 것을 제한한다.The above-mentioned rotating bar (211a) rotates the body (211b) toward the center between the pole receiving portions (210), but is in close contact with the outer surface of the connecting bar (230) to limit the body (211b) from rotating beyond a predetermined angle.

상기 몸체(211b)는 반원형상으로 형성되어, 그 내부에 상기 수평폴(101)이 삽입 걸림되도록 한다.The above body (211b) is formed in a semicircular shape so that the horizontal pole (101) can be inserted and caught inside it.

상기 몸체(211b)는 상기 회전바(211a)에 의해 정방향 또는 역방향으로 회전되어, 상기 체결홈(211b-1)에 상기 수평폴(101)이 삽입 걸림되도록 하거나 혹은 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제한다.The above body (211b) is rotated forward or backward by the above rotation bar (211a) to cause the horizontal pole (101) to be inserted and caught in the above fastening groove (211b-1) or to force the horizontal pole (101) to spread in opposite directions facing each other.

상기 몸체(211b)는 상기 회전바(211a)에 의해 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되어, 상기 체결홈(211b-1)에 삽입 체결된 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮게 위치되도록 한다.The above body (211b) is rotated in a direction opposite to the center between the pole receiving portions (210) by the above rotation bar (211a), so that the center of the horizontal pole (101) inserted and connected into the above fastening groove (211b-1) is positioned relatively lower than the height of the hinge axis (211c).

상기 몸체(211b)는 상기 침대시트(100)의 텐션에 의해 상기 폴수용부(210) 사이의 중심 방향으로 당겨지는 상기 수평폴(101)에 반발력을 부여하여, 상기 회전바(211a)가 상기 힌지축(211c)을 축으로 하향경사진 방향으로 회전되어 상기 연결바(230) 외면에 밀착 고정되도록 강제한다.The above body (211b) provides a repulsive force to the horizontal pole (101) that is pulled toward the center between the pole receiving portions (210) by the tension of the bed sheet (100), thereby forcing the rotation bar (211a) to rotate in a downwardly inclined direction about the hinge axis (211c) and be fixed in close contact with the outer surface of the connection bar (230).

상기 몸체(211b)는 상기 체결홈(211b-1)을 반원, 타원, 곡면 또는 다각형상중 어느 하나의 형상으로 형성하여, 그 내측에 수평폴(101)이 걸림 고정되도록 하는 것이 바람직하다.It is preferable that the above body (211b) be formed with the above fastening groove (211b-1) in any one of a semicircle, an ellipse, a curved surface or a polygonal shape so that a horizontal pole (101) is hung and fixed on the inside thereof.

상기 몸체(211b)는 상기 몸체(211b) 말단부에서 곡면 구조를 갖도록 굴곡지게 연장 형성되어, 상기 수평폴(101)이 상기 체결홈(211b-1) 방향으로 진입되도록 안내하는 안내곡면부(211b-2)를 더 형성한다.The above body (211b) is formed to extend in a curved manner at the end of the body (211b) to have a curved structure, thereby further forming a guide curved portion (211b-2) that guides the horizontal pole (101) to enter in the direction of the fastening groove (211b-1).

상기 안내곡면부(211b-2)는 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향과 반대되는 방향으로 회전 작동시, 상기 수평폴(101)이 상기 체결홈(211b-1) 방향으로 진입되도록 안내한다.The above guide curved surface (211b-2) guides the horizontal pole (101) to enter toward the fastening groove (211b-1) when the body (211b) is rotated in a direction opposite to the center direction between the pole receiving portions (210).

상기 폴수용부(210)는 상기 회전형 폴수용부(211)과 반대되는 상기 연결바(230) 말단부에 고정 설치되고, 외측 방향을 향하도록 개구되어 상기 수평폴(101)이 삽입 고정되도록 하는 고정형 폴수용부(212)을 더 형성한다.The above pole receiving portion (210) is fixedly installed at the end of the connecting bar (230) opposite to the above rotating pole receiving portion (211), and further forms a fixed pole receiving portion (212) that is opened toward the outside so that the horizontal pole (101) can be inserted and fixed.

상기 고정형 폴수용부(212)는 상기 연결바(230) 말단부에 고정 설치된 상태에서, 상기 침대시트(100)의 수평폴(101)이 걸림 고정된 상태를 유지하도록 한다.The above fixed pole receiving portion (212) is fixedly installed at the end of the connecting bar (230) so that the horizontal pole (101) of the bed sheet (100) is maintained in a hung and fixed state.

상기 고정형 폴수용부(212)는 상기 회전형 폴수용부(211)에 의해 상기 수평폴(101)이 서로 마주보는 방향으로 당겨지는 동안 상기 수평폴(101)이 걸림 고정되도록 상기 수평폴(101)에 반발력을 부여하여, 상기 수평폴(101)이 상기 폴수용부(210) 사이의 중심 방향으로 이동하는 것을 제한한다.The fixed pole receiving portion (212) above applies a repulsive force to the horizontal pole (101) so that the horizontal pole (101) is fixedly caught while the horizontal pole (101) is pulled in a direction facing each other by the rotating pole receiving portion (211), thereby restricting the horizontal pole (101) from moving toward the center between the pole receiving portions (210).

상기와 같이 구성되는 본 발명의 제2실시예에 따른 간이침대는 다음과 같이 사용된다.The portable bed according to the second embodiment of the present invention configured as described above is used as follows.

본 발명에 따른 간이침대는 서로 대칭 형상을 이루는 상기 연결바(230) 말단부 각각에 폴수용부(210)의 회전형 폴수용부(211)를 연결하거나 혹은 각각의 회전형 폴수용부(211) 및 고정형 폴수용부(212)를 연결할 수 있으나, 이하에서는, 상기 연결바(230) 양 말단부 각각에 회전형 폴수용부(211) 및 고정형 폴수용부(212)를 연결한 것을 예로 들어 설명하도록 한다.The portable bed according to the present invention can connect a rotating pole receiving portion (211) of a pole receiving portion (210) to each end of the connecting bars (230) that form a symmetrical shape, or can connect each rotating pole receiving portion (211) and fixed pole receiving portion (212). However, in the following, an example in which a rotating pole receiving portion (211) and a fixed pole receiving portion (212) are connected to each of the two ends of the connecting bars (230) will be described.

그리고, 상기 지지바(220)는 중앙부가 상기 보조다리(221)와 동시에 지면에 밀착될 수 있으나, 이하에서는, 상기 지지바(220)의 중앙부가 보조다리(221) 하단 높이보다 상대적으로 더 높게 형성되어, 지지바(220)가 공중에 부양되도록 지면으로 부터 정해진 높이상에 위치된 것을 예로 들어 설명한다.And, the support bar (220) can have its central portion pressed against the ground at the same time as the auxiliary leg (221), but below, an example will be described in which the central portion of the support bar (220) is formed relatively higher than the lower height of the auxiliary leg (221), and the support bar (220) is positioned at a predetermined height from the ground so as to float in the air.

먼저, 수평폴(101)이 끼워진 침대시트(100)를 구비하고, 그 상태에서 상기 수평폴(101)을 서로 마주보는 반대 방향으로 벌어지도록 강제하여, 상기 수평폴(101) 사이를 연결하는 침대시트(100)가 펼쳐지도록 한다.First, a bed sheet (100) with horizontal poles (101) inserted is provided, and in that state, the horizontal poles (101) are forced to spread in opposite directions so that the bed sheet (100) connecting the horizontal poles (101) is spread out.

이때, 상기 수평폴(101)은 상기 침대시트(100)의 양단에 끼워진 상태로 휴대되거나 혹은 상기 침대시트(101)에서 분리된 상태로 휴대되어, 사용시 상기 침대시트(101)의 양단에 끼워서 사용할 수 있다.At this time, the horizontal pole (101) can be carried in a state where it is inserted into both ends of the bed sheet (100) or carried in a state where it is separated from the bed sheet (101) and used by inserting it into both ends of the bed sheet (101).

그리고, 텐션유지부(200)의 지지바(220) 양단에서 일체로 이음연결된 연결바를 형성하되, 이 연결바(230) 중 어느 하나의 말단부에 고정형 폴수용부(212)를 고정 설치하고, 상기 고정형 폴수용부(212)와 반대되는 상기 연결바(230)의 말단부에 회전형 폴수용부(211)를 회전 가능하게 설치한다.And, a connecting bar is formed that is integrally connected at both ends of the support bar (220) of the tension maintenance member (200), a fixed pole receiving member (212) is fixedly installed at the end of one of the connecting bars (230), and a rotatable pole receiving member (211) is rotatably installed at the end of the connecting bar (230) opposite to the fixed pole receiving member (212).

이후, 상기 고정형 폴수용부(212)에 상기 침대시트(100)의 수평폴(101)을 삽입 체결하고, 그 상태에서 상기 회전형 폴수용부(211)의 회전바(211a)를 회전시켜, 상기 회전바(211a) 말단부에 연장 형성된 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심 방향을 향하도록 회전시킨다.Thereafter, the horizontal pole (101) of the bed sheet (100) is inserted and fixed into the fixed pole receiving portion (212), and in that state, the rotating bar (211a) of the rotating pole receiving portion (211) is rotated so that the body (211b) extended from the end of the rotating bar (211a) rotates toward the center between the pole receiving portions (210).

그리고, 상기 고정형 폴수용부(212)에 삽입 체결된 수평폴(101)과 반대되는 상기 침대시트(100)의 수평폴(101)을 상기 몸체(211b)의 체결홈(211b-1)으로 진입시키고, 그 상태에서 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되도록 상기 회전바(211a)를 강제 회전시킨다.Then, the horizontal pole (101) of the bed sheet (100), which is opposite to the horizontal pole (101) inserted and connected to the fixed pole receiving portion (212), is introduced into the connecting groove (211b-1) of the body (211b), and in that state, the rotating bar (211a) is forcibly rotated so that the body (211b) rotates in the opposite direction to the center between the pole receiving portions (210).

이때, 상기 회전바(211a)를 회전시키기 이전 시점에서는 상기 체결홈(211b-1)에 삽입된 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 더 높게 위치된다.At this time, before rotating the rotating bar (211a), the center of the horizontal pole (101) inserted into the fastening groove (211b-1) is positioned relatively higher than the height of the hinge axis (211c).

여기서, 상기 회전바(211a)를 상기 힌지축(211c)을 기준으로 회전시키면, 상기 몸체(211b)가 상기 폴수용부(210) 사이의 중심과 반대되는 방향으로 회전되고, 이때, 상기 몸체(211b)에 삽입 체결된 상기 수평폴(101)이 상기 안내곡면부(211b-2)를 따라 미끄러져 상기 체결홈(211b-1)으로 진입된다.Here, when the rotating bar (211a) is rotated based on the hinge axis (211c), the body (211b) is rotated in a direction opposite to the center between the pole receiving portions (210), and at this time, the horizontal pole (101) inserted and connected to the body (211b) slides along the guide curved portion (211b-2) and enters the connecting groove (211b-1).

여기서, 상기 체결홈(211b-1) 내에 삽입 체결된 수평폴(101)은 상기 몸체(211b)에 의해 서로 마주보는 반대 방향으로 벌어지면서 상기 침대시트(100)를 펼치고, 상기 회전바(211a)에 의해 연속 회전되어 그 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮은 높이에 위치된다.Here, the horizontal pole (101) inserted and fastened within the fastening groove (211b-1) is spread in opposite directions facing each other by the body (211b) to unfold the bed sheet (100), and is continuously rotated by the rotating bar (211a) so that its center is positioned at a height relatively lower than the height of the hinge axis (211c).

이때, 상기 수평폴(101)의 중심 높이가 상기 힌지축(211c)의 높이보다 상대적으로 낮은 높이에 위치되면, 상기 침대시트(100)의 텐션에 의해 상기 수평폴(101)이 상기 폴수용부(210) 사이의 중심 방향으로 당겨지고, 이때, 상기 수평폴(101)이 상기 회전형 폴수용부(211)의 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 당기게 된다.At this time, when the center height of the horizontal pole (101) is positioned at a relatively lower height than the height of the hinge axis (211c), the horizontal pole (101) is pulled toward the center between the pole receiving portions (210) by the tension of the bed sheet (100), and at this time, the horizontal pole (101) pulls the body (211b) of the rotating pole receiving portion (211) toward the center between the pole receiving portions (210).

그러면, 상기 몸체(211b)의 당김력에 의해 상기 회전바(211a)가 상기 힌지축(211c)을 기준으로 하향 경사진 방향으로 회전되어 상기 연결바(230) 외면에 밀착 고정되고, 이에따라, 상기 몸체(211b)의 회전이 제한된 상태로 상기 수평폴(101)에 반발력을 부여함으로써, 상기 수평폴(101)이 상기 몸체(211b)에 걸림 고정된다.Then, the rotating bar (211a) is rotated in a downwardly inclined direction based on the hinge axis (211c) by the pulling force of the body (211b) and is fixed in close contact with the outer surface of the connecting bar (230), and accordingly, by applying a repulsive force to the horizontal pole (101) while the rotation of the body (211b) is limited, the horizontal pole (101) is fixed by being hooked to the body (211b).

즉, 상기 수평폴(101)의 중심이 상기 힌지축(211c)의 높이보다 상대적으로 낮게 위치된 상태에서, 상기 몸체(211b)를 상기 폴수용부(210) 사이의 중심 방향으로 당기게 됨으로써, 상기 회전바(211a)가 상기 힌지축(211c)을 기준으로 하향 경사진 방향으로 강제 회전되면서 상기 연결바(230)에 밀착 고정되어, 상기 회전바(211a)가 잠김된다.That is, when the center of the horizontal pole (101) is positioned relatively lower than the height of the hinge axis (211c), the body (211b) is pulled toward the center between the pole receiving portions (210), so that the rotation bar (211a) is forcibly rotated in a downward inclined direction based on the hinge axis (211c) and is tightly fixed to the connecting bar (230), so that the rotation bar (211a) is locked.

여기서, 상기 회전형 폴수용부(211)를 회전시켜, 상기 침대시트(100)가 펼쳐진 상태를 유지하도록 함으로써, 간이침대의 사용이 가능한 상태로 변화되는 것이다.Here, by rotating the above-mentioned rotary pole receiving part (211) so that the bed sheet (100) is maintained in an unfolded state, the bed is changed to a state in which it can be used.

이때, 상기 침대시트(100) 양단에 설치된 수평폴(101)은 각각 상기 고정형 폴수용부(212) 및 회전형 폴수용부(211)의 반발력에 의해 서로 이격된 상태를 유지하면서, 상기 침대시트(100) 양단을 서로 마주보는 반대방향으로 당김으로써, 상기 침대시트(100)가 펼쳐진 상태로 유지된다.At this time, the horizontal poles (101) installed at both ends of the bed sheet (100) are kept apart from each other by the repulsive force of the fixed pole receiving portion (212) and the rotating pole receiving portion (211), respectively, and by pulling the two ends of the bed sheet (100) in opposite directions facing each other, the bed sheet (100) is maintained in an unfolded state.

그리고, 상기 지지바(220)의 양측에 절첩 가능하게 설치된 보조다리(221)가 상기 지지바(220)와 직교 각도를 이루도록 펼친 상태로, 상기 보조다리(221)를 지면에 밀착시키게 되면, 상기 지지바의 중심이 지면으로 부터 정해진 높이 상에 위치되어, 공중에 부양된 상태를 유지한다.And, when the auxiliary legs (221) that are foldable and installed on both sides of the support bar (220) are spread out to form a right angle with the support bar (220) and the auxiliary legs (221) are pressed against the ground, the center of the support bar is positioned at a predetermined height from the ground and remains suspended in the air.

그러면, 상기 지지바(220)가 공중에 부양된 상태에서, 상기 침대시트(100)에 가해지는 하중을 지탱함과 동시에, 상기 보조다리(221)에 의해 지지되어, 어느 한 방향으로 기울어지는 것이 방지된다.Then, while the support bar (220) is floating in the air, it supports the load applied to the bed sheet (100) and is supported by the auxiliary leg (221), preventing it from tilting in one direction.

그 다음, 상기 침대시트(100)에 착석하거나 혹은 드러누워 휴식을 취하는 것이다.Next, sit down or lie down on the bed sheet (100) to rest.

한편, 상기에서는 상기 지지바(220)가 공중에 부양된 상태를 예로 들어 설명하였으나, 상기 지지바(220)의 중앙부가 지면에 밀착되는 경우에는, 상기 침대시트(100)에 가해지는 하중에 의해 상기 연결바(230)가 서로 마주보는 반대방향으로 휘어지도록 허용하면서, 상기 침대시트(100)에 가해지는 하중을 떠받쳐 지지하고, 상기 침대시트(100)에 가해지는 하중 해제시, 탄성력에 의해 원상태로 복원되어 상기 연결바(230)를 원위치 시킨다.Meanwhile, the above description was given as an example of a state in which the support bar (220) is suspended in the air, but in the case where the central portion of the support bar (220) is in close contact with the ground, the load applied to the bed sheet (100) is allowed to bend in opposite directions while the connection bar (230) faces each other, thereby supporting the load applied to the bed sheet (100), and when the load applied to the bed sheet (100) is released, the connection bar (230) is restored to its original state by elastic force, thereby returning the connection bar (230) to its original position.

이때, 상기 침대시트(100)는 상기 고정형 폴수용부(212) 및 상기 회전형 폴수용부(211) 사이를 연결하는 텐션유지부(200)에 의해 양단이 서로 마주보는 반대 방향으로 벌어진 상태를 유지함으로써, 상기 침대시트(100)가 펼쳐진 상태를 유지한다.At this time, the bed sheet (100) is maintained in an unfolded state by maintaining the two ends spread in opposite directions facing each other by the tension maintaining member (200) connecting the fixed pole receiving member (212) and the rotating pole receiving member (211).

이상에서 설명한 본 발명에 따른 간이침대는 상기한 실시예에 한정되지 않고, 이하의 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양하게 변경하여 실시할 수 있는 범위까지 그 기술적 정신이 있다.The portable bed according to the present invention described above is not limited to the above-described embodiments, and anyone with ordinary skill in the art can make various modifications and implement the invention without departing from the gist of the invention claimed in the claims below, and has the technical spirit thereof.
