도 4는 이러한 종래 구성물의 일례를 도시한다.4 shows an example of such a conventional construction.
도 4는 특정 구조물을 만들기 위해서 두 개의 스트립(20)을 겹친 후, 스트립(20)의 체결공(25)들을 관통하여 볼트(10)와 너트(30)가 상호 체결됨으로써 두 개의 스트립이 특정 형태로 체결된 상태를 도시한다.4 shows that two strips 20 are formed by overlapping two strips 20 to make a specific structure, and then bolts 10 and nuts 30 are fastened to each other through fastening holes 25 of strips 20. It shows the state fastened to.
이와 같은 체결 상태의 문제점은, 볼트(10)와 너트(30)가 체결된 후에도, 볼트(10) 기둥을 회전 중심으로 하여 회동 방향으로 외력을 조금씩 지속적으로 받게 되면, 스트립(20)과 맞닿아 있는 너트(30) 면과의 마찰력으로 인해 너트(30)가 조금씩 풀리게 되고, 이를 그대로 방치하였을 경우엔 볼트(10)와 너트(30)의 체결 상태가 아예 해제되어 버릴 수도 있다는 점이다. 특히 이러한 현상이 조립된 구조물의 주요 지지 부분에서 발생하는 경우에는 구조물 자체가 완전히 무너지는 결과를 초래할 수도 있다.The problem of such a fastening state is that even after the bolt 10 and the nut 30 are fastened, when the external force is continuously received little by little in the rotational direction with the pillar of the bolt 10 as the rotation center, the contact with the strip 20 The nut 30 is slightly loosened due to friction with the surface of the nut 30, and if left unchanged, the fastening state of the bolt 10 and the nut 30 may be released at all. In particular, if this phenomenon occurs in the main supporting part of the assembled structure, the structure itself may be completely collapsed.
따라서, 도 4에 도시된 바와 같이 너트(30)를 이중으로 체결하는 방식 등이 적용되고는 있으나, 너트(30)의 추가로 인한 구조물의 복잡화, 너트(30)의 필요 이상의 소모, 작업 공수의 증가 등의 문제점을 여전히 안고 있을 뿐 아니라, 앞서 언급한 바와 같이 이러한 구성물이 유아용, 혹은 아동용의 조립 완구 형태로 제공되는 경우에는, 깔끔하지 못한 외관으로 인한 단점은 물론, 조립성을 복잡화시켜 사용을 어렵게 하는 요인이 될 수 있다.Therefore, as shown in FIG. 4, the method of double fastening the nut 30 is applied, but the complexity of the structure due to the addition of the nut 30, the consumption of the nut 30 more than necessary, In addition to the problems of increase, as mentioned above, when such a component is provided in the form of an assembled toy for a baby or a child, it is not only a disadvantage due to an unclean appearance, but also a complicated assembly. It can be a difficult factor.

도 1에 도시된 바와 같이, 본 발명의 바람직한 실시예에 따른 조립식 프레임 구성물은 볼트(10), 너트(30), 복수의 스트립(20)들로 구성된다.As shown in FIG. 1, the prefabricated frame construction according to a preferred embodiment of the present invention consists of a bolt 10, a nut 30, and a plurality of strips 20.
스트립(20)들은 보통 동일한 두께를 가지도록 제공되는 것이 바람직하며, 모든 각도에 대해서 회전 대칭인 원을 제외한, 특정 형태에 대해서 회전을 제한할 수 있는 형태의 체결공(25)들을 구비한다. 본 실시예에서 체결공(25)들은 이른바 별의 형상을 띄는데, 이는 정사각형 두 개가 45°각도로 겹쳐져 있는 외곽선의 형상이다.The strips 20 are usually provided to have the same thickness, and have fastening holes 25 of a type that can limit rotation for a particular shape, except for circles that are rotationally symmetric about all angles. In this embodiment, the fastening holes 25 have a so-called star shape, which is an outline shape in which two squares overlap each other at a 45 ° angle.
한편, 본 발명의 바람직한 실시예에 따른 볼트(10)는 헤드부(11)와 나사산이 형성되어 너트(30)와 상호 체결되는 부분인 원통형 몸체(12)를 구비하는 데, 종래의 일반적인 볼트(10)와는 특징적으로 다른 부분으로서, 헤드부(11)와 원통형 몸체(12) 사이에, 헤드부(11) 밑 면에 접하여 형성되는 비고정 기둥부(14)와, 상기 비고정 기둥부(14)와 원통형 몸체(12) 사이에 위치하는 고정 기둥부(15)를 구비한다.On the other hand, the bolt 10 according to a preferred embodiment of the present invention has a cylindrical body 12, which is a portion which is fastened to the nut 30 with the head portion 11 and the thread is formed, the conventional bolt ( As a characteristic different from 10, the non-fixed pillar portion 14 formed between the head portion 11 and the cylindrical body 12 in contact with the bottom of the head portion 11, and the non-fixed pillar portion 14 ) And a fixed pillar 15 located between the cylindrical body 12.
고정 기둥부(15)는 전술한 회전 제한 가능 체결공(25)의 형태에 의해 회전이 제한될 수 있는 단면의 형태를 가진 도형의 기둥 형상으로 형성되는데, 여기서는 체결공의 별 형상과 동일한 도형의 기둥 형태로 형성된 상태가 예시된다. 그러나, 체결공(25)의 형태에 의해 회전이 제한될 수 있는 형합적인 형태-예를 들어 정사각형기둥-를 가지기만 하면 충분하다.The fixed column part 15 is formed in a column shape of a figure having a shape of a cross section in which rotation can be restricted by the shape of the above-described rotationally restrictable fastening hole 25, and here the same shape as the star shape of the fastening hole The state formed in the form of a column is illustrated. However, it is sufficient only to have a conformal shape-for example a square column-in which rotation can be limited by the shape of the fastening hole 25.
한편, 비고정 기둥부(14)는 체결공(25) 내로 삽입되더라도 스트립(20)의 회전을 제한하지 않는 형태, 즉, 본 실시예에서는 별 형태의 체결공(25) 내에 삽입될 수 있는 단면 도형의 기둥 형태로 형성된다. 이러한 비고정 기둥부(14)는 원기둥 형상인 것이 원활한 회전을 위해 바람직하다.On the other hand, the non-fixed pillar portion 14 is a shape that does not limit the rotation of the strip 20 even if inserted into the fastening hole 25, that is, the cross section that can be inserted into the fastening hole 25 of the star shape in this embodiment It is formed in the shape of a pillar. The non-fixed pillar portion 14 is preferably in a cylindrical shape for smooth rotation.
볼트(10)가 이와 같은 구조를 가짐으로써, 다수의 스트립(20)들을 체결하는 경우, 비고정 기둥부(15)에 체결공(25)이 위치하는 스트립(20)은 체결 각도의 조절이 자유롭고 용이하게 수행될 수 있으며, 너트(30)와 접하게 되는 마지막에 위치하는 스트립(20)은 고정 기둥부(15)로 인해 회전이 제한되며, 따라서 너트(30)를 체결한 경우 스트립(20)의 접촉 회전 움직임에 의해 너트(30)의 체결 상태가 해제되는 일은 발생하지 않게 된다.When the bolt 10 has such a structure, when the plurality of strips 20 are fastened, the strips 20 in which the fastening holes 25 are positioned in the non-fixed pillars 15 can be freely adjusted. It can be easily performed, the last position of the strip 20 which is in contact with the nut 30 is limited to the rotation due to the fixed column 15, so that when the nut 30 is fastened The release state of the nut 30 is not released by the contact rotation movement.
도 2는 도 1에서 설명한 볼트(10)들의 다양한 변형 예들을 도시하는데, 이는 볼트(10)-너트(30) 조합에 의해 체결되는 스트립(20)들의 수 및 그들 중 몇 개의 스트립(20)의 각도를 특정 각도로 제한하거나 자유로운 각도 조절을 가능하게 할 것인가에 의한 기능의 차이를 부여하기 위한 예들이다.FIG. 2 shows various variants of the bolts 10 described in FIG. 1, which shows the number of strips 20 fastened by the bolt 10-nut 30 combination and several of them. Examples are provided to give a difference in function by limiting the angle to a specific angle or enabling free angle adjustment.
세 개의 볼트(10) 중 도면상 가장 좌측에 도시된 볼트(10)는, 비고정 기둥부(14)와 고정 기둥부(15)의 높이 a, b가 거의 동일하게 형성되어 있음을 확인할 수 있는데, 이들의 높이 a, b가 스트립(20)의 두께에 해당된다면, 이 볼트(10)는 두 개의 스트립(20)을 체결하기 위한 볼트(10)이고, 두 스트립(20)의 각도 조절은 제한되지 않고 자유롭게 설정 가능함을 의미한다. 물론, 너트(30)와 접촉하게 되는 스트립(20)은 고정 기둥부(15)에 의해 체결된 너트(30)에 대한 상대적 회동이 제한되므로 접촉 회동에 의한 너트(30) 풀림 현상이 발생하지 않는다.Of the three bolts 10, the bolt 10 shown on the left side of the drawing, it can be seen that the height a, b of the non-fixed pillar portion 14 and the fixed pillar portion 15 is formed almost the same. If their heights a, b correspond to the thickness of the strips 20, this bolt 10 is a bolt 10 for fastening the two strips 20, and the angle adjustment of the two strips 20 is limited. It means that it can be set freely. Of course, since the relative rotation with respect to the nut 30 fastened by the fixed pillar 15 is limited to the strip 20 coming into contact with the nut 30, the nut 30 is not loosened due to the contact rotation. .
도면상 중앙에 도시된 볼트(10)는 고정 기둥부(15)의 높이 b가 비고정 기둥부(14) 높이 a의 두 배 정도 되는 것을 확인할 수 있는데, 비고정 기둥부(14)의 높이가 스트립(20)의 두께에 해당된다면, 이 볼트(10)는 세 개의 스트립(20)을 체결할 수 있는 구조의 볼트(10)이며, 볼트 헤드부(11)에 접한 스트립(20)과 그 밑의 중앙 스트립(20)은 상호 자유로운 각도 조절이 가능한 반면, 중앙의 스트립(20)과 그 밑의 하단 스트립(20)은 체결공(25)의 형태에 의해 제한되는 각도, 즉 45°단위의 각도 조절만이 가능하다.The bolt 10 shown in the center of the drawing can be confirmed that the height b of the fixed column 15 is about twice the height a of the non-fixed column 14, but the height of the non-fixed column 14 is If this corresponds to the thickness of the strip 20, this bolt 10 is a bolt 10 of a structure capable of fastening three strips 20, the strip 20 in contact with the bolt head 11 and the bottom thereof. The central strip 20 of the mutually free angle control is possible, while the central strip 20 and the lower strip 20 below the angle is limited by the shape of the fastening hole 25, that is the angle in 45 ° unit Only adjustment is possible.
도면상 우측에 도시된 볼트(10)는 비고정 기둥부(14)의 높이 a가 고정 기둥부(15) 높이 b의 두 배 정도 되는 것을 확인할 수 있는데, 고정 기둥부(15)의 높이가 스트립(20)의 두께에 해당된다면, 이 볼트(10)는 세 개의 스트립(20)을 체결할 수 있는 구조의 볼트(10)이며, 체결된 모든 스트립(20) 상호간의 각도는 자유롭게 조절될 수 있는 반면, 너트(30)와 접촉하게 되는 하단의 스트립(20)은 고정 기둥부(15)에 의해 체결된 너트(30)에 대한 상대적 회동이 제한되어 접촉 회동에 의한 너트(30) 풀림 현상이 발생하지 않는 구조이다.The bolt 10 shown on the right side of the drawing can confirm that the height a of the non-fixed pillar portion 14 is about twice the height b of the fixed pillar portion 15, and the height of the fixed pillar portion 15 is stripped. If this corresponds to the thickness of 20, this bolt 10 is a bolt 10 of the structure capable of fastening three strips 20, the angle between all the fastened strips 20 can be freely adjusted On the other hand, the lower strip 20 that comes into contact with the nut 30 has a limited relative rotation with respect to the nut 30 fastened by the fixed pillar 15, so that the nut 30 is loosened due to contact rotation. It is not structure.
이러한, 볼트(10), 너트(30) 및 복수의 스트립(20)들의 체결 상태를 나타낸 도면이 도 3이다.3 is a view illustrating a fastening state of the bolt 10, the nut 30, and the plurality of strips 20.
도 3에는 두 개의 스트립(20)이 볼트(10), 너트(30) 조합에 의해 체결된 상태를 도시하는데, 앞서 언급한 바와 같이 스트립(20)의 두께는 일정하게 형성되어 있다. 이 스트립(20)의 두께를 c라고 할 때, 비고정 기둥부(14)의 높이 a, 고정 기둥부(15)의 높이 b, 스트립(20)의 두께 c 및 볼트(10)와 너트(30)에 의해 체결될 수 있는 스트립(20)의 수 n의 사이에는 다음과 같은 관계가 있다.3 shows a state in which two strips 20 are fastened by a combination of a bolt 10 and a nut 30, and as mentioned above, the thickness of the strip 20 is constant. When the thickness of the strip 20 is c, the height a of the unfixed pillar portion 14, the height b of the fixed pillar portion 15, the thickness c of the strip 20, and the bolt 10 and the nut 30 There is the following relationship between the number n of strips 20 that can be fastened by
(n-1)×c ＜ a+b ≤ n×c(n-1) × c <a + b ≦ n × c
x×c ≤ a ＜ (x+1)×cx × c ≤ a <(x + 1) × c
(여기서, n은 2≤n 인 정수, x는 x＜n인 정수)(Where n is an integer of 2≤n and x is an integer of x <n)
상기 식은 다음과 같은 의미를 가진다.The formula has the following meaning.
첫째, 비고정 기둥부(14)와 고정 기둥부(15)의 전체 높이는, 체결되는 스트립(20)들의 전체 두께와 같거나 그보다 작아야 한다. 이는 너트(30)를 체결할 경우 스트립(20)들이 조여지기 위한 조건이다. First, the total height of the non-fixed pillar portion 14 and the fixed pillar portion 15 should be less than or equal to the overall thickness of the strips 20 to be fastened. This is a condition for the strips 20 to be tightened when the nut 30 is tightened.
둘째, 비고정 기둥부(14)와 고정 기둥부(15)의 전체 높이는, 체결되는 스트립(20)들의 전체 두께에서 스트립(20)의 단위 두께(스트립 한 개의 두께)를 뺀 높이 보다 작아져서는 안된다. 이는 너트(30)와 가장 인접한 가장 하단의 스트립(20)의 체결공(25)이 고정 기둥부(15)에 형합되기 위한 조건이다.Second, the total height of the non-fixed column 14 and the fixed column 15 should not be less than the total thickness of the strips 20 to be joined minus the unit thickness of the strip 20 (the thickness of one strip). . This is a condition for the fastening hole 25 of the lowermost strip 20 closest to the nut 30 to be joined to the fixed pillar 15.
셋째, n개의 스트립들 중 x개의 스트립(20)의 회동 각도를 자유롭게 조절하기 위해서는, 비고정 기둥부(14)의 높이는 x개의 스트립(20)들의 총 두께보다는 같거나 커야 하고, x+1개의 스트립(20)들의 총 두께보다는 작아야한다. 예를 들어, 3개의 스트립(20)이 체결되고, 스트립(20)의 두께는 10mm, 이 중 스트립(20) 두 개의 회동을 자유롭게 할 수 있는 구조의 볼트라면(도 2의 최 우측 볼트처럼), 비고정 기둥부(14)의 높이는 20mm보다는 크거나 같고, 30mm보다는 작아야 한다는 것이다. 이때, 비고정 기둥부(14)와 고정 기둥부(15)의 전체 높이는 30mm 보다 작아야 하므로, 비고정 기둥부(14)의 높이가 예를 들어 22mm라 한다면, 고정 기둥부(15) 높이 b 는 0 ＜ b ≤ 8mm 의 값을 가져야 한다는 뜻이다.Third, in order to freely adjust the rotation angle of the x strips 20 of the n strips, the height of the non-fixed column 14 must be equal to or greater than the total thickness of the x strips 20 and x + 1 pieces. It should be smaller than the total thickness of the strips 20. For example, if three strips 20 are fastened and the strips 20 are 10 mm thick, of which the strips 20 are free to rotate (as in the rightmost bolt of FIG. 2) , The height of the non-fixed column 14 is greater than or equal to 20mm, and less than 30mm. At this time, since the total height of the non-fixed pillar portion 14 and the fixed pillar portion 15 should be less than 30mm, if the height of the non-fixed pillar portion 14 is 22mm, the height b of the fixed pillar portion 15 is This means that it should have a value of 0 <b ≤ 8 mm.
이와 같이 구성됨으로써, 본 발명은 도 4 등을 통해 예시된 종래 기술에서 너트(30)가 쉽게 풀리거나 풀리지 않도록 하기 위해 두 개 이상을 체결해야 했던 점으로 인한 단점 들을 극복할 수 있는 것은 물론, 본 발명 발명자의 특허 제965278호만으로는 충분하지 않았던, 체결되는 스트립(20)들의 각도를 자유롭게 변경하거나 특정 각도로 고정하는 것을 선택적으로 적용하면서도, 너트(30)와 맞닿는 마지막 스트립(20)의 회동에 의해 너트(30)가 풀리는 것을 효과적으로 방지하는 효과를 더욱 보충할 수 있게 된 것이다.In this way, the present invention can overcome the disadvantages due to the need to fasten two or more in order to prevent the nut 30 from being easily loosened or loosened in the prior art illustrated in FIG. The inventors' patent No. 965278 alone was not sufficient, by the rotation of the last strip 20 in contact with the nut 30 while optionally applying freely changing or fixing the angle of the fastening strips 20 at a particular angle. The nut 30 will be able to further supplement the effect of effectively preventing the loosening.
이상과 같이 본 발명을 바람직한 실시예 및 이를 도시한 도면에 의해 설명하였으나, 본 발명은 도시되고 설명된 실시예에 의한 구성 및 작용으로 한정되는 것이 아니다. 오히려 첨부된 특허청구범위의 사상 및 범주를 일탈함이 없이 본 발명에 대한 다수의 변경 및 수정이 가능함을 당업자들은 잘 이해할 수 있을 것이다. 따라서, 그러한 모든 적절한 변경 및 수정과 균등물들도 본 발명의 범위에 속하는 것으로 간주되어야 할 것이다.As described above, the present invention has been described with reference to the preferred embodiments and drawings, but the present invention is not limited to the configuration and operation according to the illustrated and described embodiments. Rather, those skilled in the art will appreciate that many variations and modifications of the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
