Description

조립식 앵글 체결구조{Fastening Structure for Prefabricated Angle}Prefabricated angle fastening structure {Fastening Structure for Prefabricated Angle}

본 발명은 조립식 앵글 체결 구조에 관한 것으로서, 수직 또는 수평 프레임에 형성된 체결공과 걸림편을 편리하게 조립 가능한 기술에 관한 것이다.The present invention relates to a prefabricated angle fastening structure, and to a technology capable of conveniently assembling a fastening hole and a hooking piece formed in a vertical or horizontal frame.

앵글은 단면이 각진 모양으로 형성된 길이를 가진 부재로서, 앵글 단면의 규격과 단위무게는 용도에 따라 다양하다. 적당한 길이로 절단된 다수의 앵글 부재는 볼트와 너트로 체결되어 조립식 선반이나 평상 등의 틀을 구성할 수 있다.An angle is a member with a length formed in an angled cross-section, and the standard and unit weight of the angle cross-section vary depending on the use. A plurality of angle members cut to an appropriate length may be fastened with bolts and nuts to constitute a frame such as a prefabricated shelf or flat table.

그러나 이와 같은 볼트와 너트의 체결은 조립과 해체에 작업 시간이 많이 소요되는 문제가 있으며, 그에 따라 수직부재와 수평부재를 서로 끼워 조립할 수 있는 개선된 기술이 아래 (특허문헌 0001)에 제안되었다.However, the fastening of the bolt and the nut has a problem in that it takes a lot of work time for assembly and disassembly, and accordingly, an improved technique for assembling by inserting a vertical member and a horizontal member is proposed below (Patent Document 0001).

상기 기술은 다수의 체결공들이 마련된 수직부재와 상기 체결공들에 삽입되는 걸림편을 구비한 수평부재를 포함하여, 볼트와 너트 없이도 쉽게 앵글을 조립 또는 해체할 수 있으며 외관이 양호하다.The technology includes a vertical member provided with a plurality of fastening holes and a horizontal member having a locking piece inserted into the fastening holes, so that angles can be easily assembled or disassembled without bolts and nuts, and the appearance is good.

그러나, 상기 기술은 체결공의 상변이 하변보다 긴 사다리꼴로 형성된 반면 상기 걸림편의 상하변은 동일한 길이로 형성되어 체결공에 끼웠을 때 결합력이 부족한 문제가 있다. 구조상 체결공의 양측변이 걸림편의 하부 모서리 부분만을 꽉 조이게 되어 마찰면적이 제한되므로 결합력이 약할 수 밖에 없는 것이다. 또한, 이러한 구조는 작업자가 망치 등을 이용하여 부재에 충격을 가할 경우 체결공의 측변이나 걸림편이 깨지는 등 부재의 손상을 유발할 수 있다.However, in the above technique, while the upper side of the fastening hole is formed in a trapezoidal shape longer than the lower side, the upper and lower sides of the locking piece are formed to have the same length, so there is a problem in that the coupling force is insufficient when inserted into the fastening hole. Due to the structure, both sides of the fastening hole tighten only the lower edge of the locking piece, and the friction area is limited, so the bonding force is inevitably weak. In addition, such a structure may cause damage to the member, such as when the worker applies an impact to the member using a hammer or the like, the side of the fastening hole or the engaging piece is broken.

본 발명은 체결공을 구비한 수직부재와 걸림편을 구비한 수평부재를 포함하는 조립식 앵글 체결구조로서, 상기 체결공은, 상단의 폭이 하단의 폭보다 크고 양 측변이 서로 대칭으로 경사지는 체결부를 포함하며, 상기 걸림편은, 상기 수평부재의 면에서 수직으로 돌출 형성된 돌출부와, 상기 돌출부의 종단에서 절곡되어 형성된 걸림부를 포함하고, 상기 돌출부가 상기 체결부의 양 측변과 마찰하여 끼움 결합된다.The present invention is a prefabricated angle fastening structure comprising a vertical member having a fastening hole and a horizontal member having a locking piece, wherein the fastening hole has an upper width greater than a lower end and both sides are symmetrically inclined to each other. It includes a portion, wherein the engaging piece includes a protrusion formed to protrude vertically from the surface of the horizontal member, and a catching portion formed by bending at the end of the protrusion, and the protrusion is fitted by friction with both sides of the fastening portion.

또한, 상기 돌출부는, 상기 체결부의 양 측변의 경사와 같은 경사로 형성된 마찰부를 포함한다.In addition, the protrusion includes a friction portion formed with an inclination equal to the inclination of both sides of the fastening portion.

바람직하게는, 상기 마찰부는, 상기 돌출부의 중심 수평선을 기준으로 상하 대칭으로 형성된다.Preferably, the friction part is formed vertically symmetrically with respect to a central horizontal line of the protrusion part.

또한, 바람직하게는, 상기 돌출부는, 상기 체결부의 양 측변에 각각 마찰되도록 분리된 복수의 부재로 구성된다.In addition, preferably, the protrusion is composed of a plurality of members separated so as to rub against both sides of the fastening portion, respectively.

또한, 바람직하게는, 상기 체결공은, 상기 걸림편이 삽입 가능하도록 넓게 형성된 가이드부와, 상기 가이드부의 측변에서 하향 경사로 구비되어 상기 체결부와 연결되는 단차부를 더 포함한다.In addition, preferably, the fastening hole further includes a guide portion formed wide so that the engaging piece can be inserted, and a step portion provided with a downward slope at the side of the guide portion and connected to the fastening portion.

In the description of the present invention, when it is determined that the description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the description thereof is omitted.

도 1은 본 발명의 실시예에 따른 조립식 앵글 체결구조(100)가 체결된 모습을 도시한 것이다. 도 2는 본 발명의 실시예에 따른 체결공(112)을 도시한 것이다. 도 3a는 본 발명의 실시예에 따른 걸림편(122)의 사시도이며, 도 3b는 걸림편(122)의 측면도이고, 도 3c는 걸림편(122)의 단면도이다. 도 4는 체결공(112)에 걸림편(122)이 끼워진 모습을 걸림편(122)의 단면이 보이도록 도시한 것이다.1 shows a state in which the prefabricated angle fastening structure 100 according to an embodiment of the present invention is fastened. 2 shows a fastening hole 112 according to an embodiment of the present invention. 3A is a perspective view of the locking piece 122 according to an embodiment of the present invention, FIG. 3B is a side view of the locking piece 122 , and FIG. 3C is a cross-sectional view of the locking piece 122 . 4 illustrates a state in which the locking piece 122 is fitted in the fastening hole 112 so that a cross-section of the locking piece 122 is visible.

도 1을 참조하면, 조립식 앵글 체결구조(100)는 체결공(112)과 상기 체결공(112)에 삽입되어 끼움 결합이 가능한 걸림편(122)을 포함한다. 걸림편(122)은 수평부재(120)에 구비되며, 체결공(112)은 수직부재(110)에 구비될 수 있다.Referring to FIG. 1 , the prefabricated angle fastening structure 100 includes a fastening hole 112 and a locking piece 122 that is inserted into the fastening hole 112 and can be fitted. The locking piece 122 may be provided on the horizontal member 120 , and the fastening hole 112 may be provided on the vertical member 110 .

걸림편(122)이 체결공(112)에 삽입되고 끼워지면서 수평부재(120)와 수직부재(110)를 결합할 수 있으며, 이를 통해 용도에 맞는 구조물을 설치할 수 있다.As the locking piece 122 is inserted and fitted into the fastening hole 112 , the horizontal member 120 and the vertical member 110 may be coupled, and a structure suitable for the purpose may be installed through this.

도 2를 참조하면, 체결공(112)이 확대되어 도시된다. 체결공(112)은 상단의 폭(W1)이 하단의 폭(W2)보다 크고 양 측변이 서로 대칭으로 경사지는 체결부(112a)를 포함한다. 상단에서 하단으로 갈수록 폭이 점점 좁아지는 형태이므로, 양 측변은 경사진다. 따라서, 걸림편(122)은 체결공(112)의 상단에서 삽입되어 하단으로 끼워질 수 있으며, 체결부(112a)의 양 측변은 걸림편(122)을 꽉 조여 고정한다.Referring to FIG. 2 , the fastening hole 112 is enlarged. The fastening hole 112 includes a fastening part 112a in which the width W1 of the upper end is greater than the width W2 of the lower end and both sides are inclined symmetrically to each other. Since the width is gradually narrowed from the top to the bottom, both sides are inclined. Accordingly, the locking piece 122 may be inserted from the upper end of the fastening hole 112 and fitted to the lower end, and both sides of the fastening part 112a are fixed by tightly tightening the locking piece 122 .

또한, 체결공(112)은 걸림편(122)이 편리하게 삽입 가능하도록 넓게 형성된 가이드부(112b)와, 가이드부(112b)의 측변에서 하향 경사로 구비되어 체결부(112a)와 연결되는 단차부(112c)를 더 포함할 수 있다.In addition, the fastening hole 112 is provided with a guide portion 112b that is wide enough so that the engaging piece 122 can be conveniently inserted, and a step portion connected to the fastening portion 112a by being provided with a downward slope at the side of the guide portion 112b. (112c) may be further included.

가이드부(112b)는 걸림편(122)의 단면적보다 충분히 큰 넓이로 형성되어 작업자가 쉽게 걸림편(122)을 체결공(112)에 삽입할 수 있도록 한다. 또한, 단차부(112c)의 하향 경사는 가이드부(112b)에 삽입된 걸림편(122)이 체결부(112a)로 매끄럽게 끼워지도록 하여 작업자의 편의성을 높인다.The guide portion 112b is formed to have a width sufficiently larger than the cross-sectional area of the locking piece 122 so that the operator can easily insert the locking piece 122 into the fastening hole 112 . In addition, the downward inclination of the step portion 112c increases the convenience of the operator by smoothly fitting the engaging piece 122 inserted into the guide portion 112b into the fastening portion 112a.

도3a 내지 도3c를 참조하면, 걸림편(122)의 상세 모습이 도시된다. 걸림편(122)은 수평부재(120)의 면에서 수직으로 돌출 형성된 돌출부(124)와 돌출부(124)의 종단에서 절곡되어 형성된 걸림부(126)를 포함한다. 걸림편(122)을 끼울 때, 돌출부(124)는 체결부(112a)의 양 측변에 접촉하여 마찰하며, 마찰력에 의한 고정력으로 끼움 결합된다. 걸림부(126)는 끼움 결합된 걸림편(122)이 체결공(112)에서 수평방향으로 빠지지 않도록 하며, 고정력을 향상시킨다.Referring to Figures 3a to 3c, a detailed view of the locking piece 122 is shown. The locking piece 122 includes a protrusion 124 vertically protruding from the surface of the horizontal member 120 and a locking part 126 formed by bending at the end of the protrusion 124 . When the engaging piece 122 is fitted, the protrusion 124 contacts and rubs against both sides of the fastening portion 112a, and is fitted with a fixing force by frictional force. The locking part 126 prevents the fitting locking piece 122 from falling out in the horizontal direction from the fastening hole 112, and improves the fixing force.

한편, 도3c를 참조하면, 수평부재(120)와 함께 돌출부(124)의 단면이 도시된다. 돌출부(124)는 체결부(112a)의 양 측변의 경사와 같은 경사로 형성된 마찰부(124a)를 포함하며, 마찰부(124a)는 돌출부(124)의 중심 수평선(10)을 기준으로 상하 대칭으로 형성될 수 있다.Meanwhile, referring to FIG. 3C , a cross-section of the protrusion 124 together with the horizontal member 120 is shown. The protrusion 124 includes a friction part 124a formed with the same inclination as the inclination of both sides of the fastening part 112a, and the friction part 124a is vertically symmetrical with respect to the central horizontal line 10 of the protrusion 124 . can be formed.

도4에 도시하듯이, 마찰부(124a)는 체결부(112a)의 양 측변 경사와 동일한 경사를 포함함으로써, 끼움 결합 시 마찰력이 발생하는 접촉면적을 넓힐 수 있으며, 고정력을 향상시킨다. 또한, 끼움 결합으로 인한 압력이 부재의 한 점에 집중되지 않고 경사 전체에 고루 분포하게 되므로 설치 중 부재가 깨지거나 손상될 확률이 현저히 감소한다.As shown in FIG. 4 , the friction part 124a includes the same slope as the inclination of both sides of the fastening part 112a, so that the contact area where frictional force occurs during fitting can be widened, and the fixing force is improved. In addition, since the pressure due to the fitting is not concentrated on one point of the member but is evenly distributed over the slope, the probability of the member being broken or damaged during installation is significantly reduced.

한편, 마찰부(124a)가 중심 수평선(10)을 기준으로 상하 대칭으로 형성되므로,작업자는 수평부재(120)를 상하 구별없이 끼울 수 있다. 걸림편(122)의 모양을 유심히 관찰하여 수평부재(120)의 상하를 판별하는 것은 작업자에 따라 때때로 불편함을 유발하기도 하며, 빠른 작업을 저해한다. 따라서, 상기의 특징은 작업자의 편의와 작업속도를 높이며, 처음 작업하는 사람도 직관적으로 쉽게 구조물을 설치할 수 있다.On the other hand, since the friction part 124a is formed vertically symmetrically with respect to the central horizontal line 10 , the operator can insert the horizontal member 120 without distinction of top and bottom. Determining the top and bottom of the horizontal member 120 by carefully observing the shape of the locking piece 122 may sometimes cause discomfort depending on the operator, and impede fast work. Therefore, the above features increase the convenience and work speed of the operator, and even a first-time worker can intuitively and easily install the structure.

한편, 돌출부(124)는 체결부(112a)의 양 측변에 각각 접촉되도록 분리된 복수의 부재로 구성된다. 즉, 도3c와 같이 체결부(112a)의 양 측변에 각각 대응되도록 좌우 대칭인 한 쌍의 부재가 돌출부(124)를 구성할 수 있다. 상기 부재는 서로 일정 거리 이격된다. 이와 같이 서로 분리된 한 쌍의 부재가 돌출부(124)를 구성함으로써, 끼움 결합 시 돌출부(124)가 미세한 변위를 허용하고 적은 힘으로 끼움 결합이 가능하다.On the other hand, the protrusion 124 is composed of a plurality of members separated so as to contact both sides of the fastening portion 112a, respectively. That is, as shown in FIG. 3C , a pair of left-right symmetrical members may constitute the protrusion 124 so as to correspond to both sides of the fastening part 112a, respectively. The members are spaced apart from each other by a predetermined distance. As a pair of members separated from each other in this way constitutes the protrusion 124 , the protrusion 124 allows a minute displacement during fitting, and the fitting can be performed with a small force.

돌출부(124)는 수평부재(120)를 가공, 성형하여 만드는 것이 바람직하다. 이 경우, 돌출부(124)는 수평부재(120)와 동일한 재질로 구비되며, 상기 재질에 따른 탄성을 갖는다. 따라서, 상기 한 쌍의 부재는 끼움 결합 시 작업자의 힘에 의한 미세한 변위를 허용하지만, 결합을 해제하면 다시 탄성에 의해 원래 위치로 복원된다.The protrusion 124 is preferably made by processing and molding the horizontal member 120 . In this case, the protrusion 124 is made of the same material as the horizontal member 120 and has elasticity according to the material. Accordingly, the pair of members allow a minute displacement due to the force of the operator at the time of fitting, but when the coupling is released, it is restored to its original position by elasticity again.

바람직하게는, 돌출부(124)는 끼움 결합 시 꺽임을 방지하기 위한 보강재(124b)를 더 포함할 수 있다. 상기 보강재(124b)는 마찰부(124a)의 반대측에 형성되며, 중심 수평선(10)이 지나는 위치에 형성되는 것이 효과적이다.Preferably, the protrusion 124 may further include a reinforcing material 124b for preventing bending during fitting. The reinforcing material 124b is formed on the opposite side of the friction part 124a, and it is effective to be formed at a position through which the central horizontal line 10 passes.

보강재(124b)는 끼움 결합 시 돌출부(124)가 과도하게 꺽여 영구적으로 변형될 가능성을 현저히 낮추며, 돌출부(124)의 탄성복원력을 높여 결합력이 증대된다.The reinforcing material 124b significantly lowers the possibility that the protrusion 124 is excessively bent and permanently deformed during fitting, and the coupling force is increased by increasing the elastic restoring force of the protrusion 124 .

보강재(124b)의 형상, 재질 등은 전술한 기술사상의 핵심이 변경되지 않는 범위에서 당업자가 적절하게 선택할 수 있을 것이다.The shape, material, etc. of the reinforcing material 124b may be appropriately selected by those skilled in the art within a range that does not change the core of the above-described technical idea.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 당업자에게 명백할 것이다.The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it will be apparent to those skilled in the art that various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention.
