용접식 창짝 프로파일 단차방지구{Welded sash profile step prevention device}Welded sash profile step prevention device

본 발명은 용접식 창짝 프로파일 단차방지구에 관한 것으로, 보다 상세하게는 용접식 창짝을 제작하는 과정에서 창짝용 프로파일의 절단면을 용접할 때 용접부위의 변형과 단차가 발생하지 않도록 하여 절단면이 깔끔하게 용접되도록 유도할 수 있을 뿐만 아니라 단차방지구가 용접 작업도중 분리 이탈됨없이 안정적으로 결합상태를 유지할 수 있도록 개선된 용접식 창짝 프로파일 단차방지구에 관한 것이다.The present invention relates to a welded window sill profile step prevention device, and more particularly, when welding the cut surface of the window sill profile in the process of manufacturing a welded spearhead, the cut surface is welded neatly by preventing the deformation and step difference of the welded part from occurring It relates to an improved welded window sill profile step preventer that not only can induce it to be possible, but also allows the step preventer to stably maintain a combined state without separation and separation during welding.

건축물의 내외부에는 채광 및 환기를 목적으로 하는 각종의 창호가 마련된다. 이러한 창호는 건축물의 개구부에 설치되는 창틀 및 이에 결합하는 창짝으로 구성되는 것으로서 개폐방식에 따라 여닫이식, 미닫이식 등으로 구분되고, 재질에 따라 목재 창호, 합성수지 창호, 금속 창호 등으로 구분되며, 이중 미닫이식의 합성수지 창호가 최근 창호의 주를 이루고 있다.Various windows are provided inside and outside the building for the purpose of lighting and ventilation. These windows and doors are composed of a window frame installed in the opening of a building and a window sill coupled thereto, and are divided into opening and closing types depending on the opening and closing method, and divided into wooden windows, synthetic resin windows, metal windows, etc. Sliding-type synthetic resin windows are the mainstay of windows these days.

이때, 창짝은 합성수지로 압출된 프로파일 간의 결합에 의해 사각형의 프레임 형태로 형성되는데, 통상 상하좌우 4개의 프로파일 코너면을 45°경사로 절삭한 후 서로 맞대게 한 상태에서 볼트 체결함으로써 사각형상의 창짝을 완성하게 된다.At this time, the window sill is formed in the form of a rectangular frame by the bonding between the profiles extruded from synthetic resin. Usually, after cutting the upper, lower, left, and right four profile corners at a 45° angle and bolting them together, the rectangular window sill is completed. will do

그런데, 이 경우에는 작업공수가 많고 정확한 수직도를 맞추기 어려운 점이 있어 최근에는 [선행기술문헌]과 같이, 45°경사로 맞대어진 프로파일의 양측면에 가열판을 대고, 이 가열판에 열을 가해 접촉되는 부위를 용접하는 방식이 사용되고 있다.However, in this case, there is a lot of work and it is difficult to set the correct verticality. The welding method is used.

그런데, 합성수지로 압출성형되는 창짝용 프로파일은 성형되는 과정에서 보강심을 설치하기 위해 마련되는 중공부가 일정하게 성형되지 않고 파도치듯이 휨변형이 생기기도 하고, 가공편차로 인해 안쪽으로 말려들면서 편차가 생기기도 하기 때문에 이렇게 된 프로파일을 맞대 상태에서 용접하게 되면 단차가 생겨 가열판과의 접촉상태가 나빠져 용접 불량을 일으키는 경우가 많다.However, in the window profile extrusion molded with synthetic resin, the hollow part provided for installing the reinforcing core is not formed uniformly during the molding process, and bending deformation occurs like a wave. Also, if the profile is welded in a butt state, there is a step difference, which in many cases causes poor contact with the heating plate, resulting in poor welding.

이와 같은 용접 불량을 방지하기 위해 여러 형태의 부재를 사용하기도 하지만 쉽게 잘 빠지고, 끼움 위치를 조절하기 어려워 제 기능을 수행하지 못했다.In order to prevent such welding defects, various types of members are used, but they come out easily, and it is difficult to adjust the fitting position, so it cannot perform its function.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as being limited to the embodiments described herein.

도 1 내지 도 5에 예시된 바와 같이, 본 발명에 따른 용접식 창짝 프로파일 단차방지구는 방지구본체(100)를 포함한다.As illustrated in FIGS. 1 to 5 , the welding type changjak profile step prevention device according to the present invention includes a preventive device body 100 .

그리고, 상기 방지구본체(100)는 창짝 프로파일(200)의 사선면(210)에 삽입 고정된다.And, the prevention sphere body 100 is inserted and fixed to the slanted surface 210 of the changjak profile 200 .

이것은 상기 창짝 프로파일(200)의 사선면(210)이 다른 프로파일의 사선면에 맞대어진 상태에서 가열판을 이용하여 용접되기 때문에 용접될 때 사선면(210)의 변형을 잡아 고품질 상태로 용접되게 하기 위함이다.This is because the slanted surface 210 of the slanted profile 200 is welded using a heating plate while facing the slanted surface of the other profile. to be.

이때, 상기 창짝 프로파일(200)에는 보강심을 설치하기 위한 용도로 형성되는 중공부(220)가 마련된다.At this time, a hollow portion 220 formed for the purpose of installing a reinforcing core is provided in the window sill profile 200 .

아울러, 상기 중공부(220)는 창짝 프로파일(200)의 길이방향으로 길게 형성되기 때문에 당연히 사선면(210)을 관통하여 형성된다.In addition, since the hollow part 220 is formed to be long in the longitudinal direction of the changjjak profile 200 , it is naturally formed through the oblique surface 210 .

그리고, 상기 방지구본체(100)는 상기 사선면(210)에서 상기 중공부(220)에 끼워져 고정된다.In addition, the prevention sphere body 100 is fixed by being fitted into the hollow part 220 on the diagonal surface 210 .

이를 위해, 상기 방지구본체(100)의 선단부는 수직면(110)을 형성하고, 후단부는 상기 사선면(210)에 대응되게 45°각도로 테이퍼진 테이퍼면(120)을 형성한다.To this end, the front end of the prevention sphere body 100 forms a vertical surface 110 , and the rear end forms a tapered surface 120 tapered at a 45° angle to correspond to the oblique surface 210 .

따라서, 상기 선단부가 먼저 삽입되고, 후단부는 사선면(210)과 테이퍼면(120)이 일치되게 배치된다.Accordingly, the front end is inserted first, and the rear end is arranged so that the oblique surface 210 and the tapered surface 120 coincide.

뿐만 아니라, 상기 방지구본체(100)는 둘레방향으로 따라 다수의 요철홈(130)이 형성되는데, 이는 강도를 보강 및 증대시켜 중공부(220)에 삽입되었을 때 창짝 프로파일(200)의 중공부(220) 내측변(內側邊)이 안쪽으로 말려든 변형을 펴서 가열판과의 사이에서 단차가 생기지 않도록 하기 위함이다.In addition, the prevention sphere body 100 is formed with a plurality of concave-convex grooves 130 along the circumferential direction, which reinforces and increases the strength, so that when inserted into the hollow part 220, the hollow part of the changjak profile 200 (220) The inner edge (內側邊) is to straighten the curled inward deformation so that there is no step difference between the heating plate.

무엇보다도, 본 발명에서는 상기 방지구본체(100)의 선단부 내측변 양측에 탄성후크(140)를 형성한 것을 주요한 특징으로 한다.Above all, in the present invention, the main feature is that elastic hooks 140 are formed on both sides of the inner side of the front end of the preventive device body 100 .

상기 탄성후크(140)는 도 2 및 도 3의 예시와 같이, 선단부 내측변의 일부가 절개선(142)을 따라 절개되어 형성된다.As shown in the examples of FIGS. 2 and 3 , the elastic hook 140 is formed by cutting a part of the inner side of the front end along the incision line 142 .

특히, 상기 탄성후크(140)는 일측면, 바람직하게는 중공부(220)의 내부와 접촉하는 내측면이 도톰하게 돌출되어 올라와 넓은 면에 걸쳐 후크형상을 갖도록 형성된 것이 특징이다.In particular, the elastic hook 140 is characterized in that one side, preferably, the inner surface in contact with the inside of the hollow part 220 protrudes thickly and is formed to have a hook shape over a wide surface.

이렇게 되면, 상기 방지구본체(100)를 중공부(220)에 끼웠을 때 상기 탄성후크(140)가 중공부(220)의 내측면과 탄성적으로 접촉되면서 일종의 강제끼움 형태로 압입되기 때문에 고정력이 급격히 높아져 방지구본체(100)가 쉽게 분리 이탈되지 않을 뿐만 아니라 고정안정성을 높일 수 있다.In this case, when the prevention sphere body 100 is inserted into the hollow part 220, the elastic hook 140 is in elastic contact with the inner surface of the hollow part 220 and is press-fitted in a kind of forced-fitting form. This is rapidly increased, so that the preventive sphere body 100 is not easily separated and separated, and the fixing stability can be improved.

이 상태에서 가열판을 대고 프로파일의 사선면(210)을 서로 용접하게 되면 상기 방지구본체(100)가 중공부(220) 내부에 꽉 채워진 상태로 중공부(220) 외측면을 최대한 확장시켜주기 때문에 가열판과의 단차가 생기지 않게 되어 용접품질을 향상시킬 수 있고, 나아가 방지구본체(100)도 함께 용융되면서 용접되게 되므로 용접면의 고정력도 향상되게 된다.In this state, when a heating plate is applied and the oblique faces 210 of the profile are welded to each other, the prevention sphere body 100 expands the outer surface of the hollow part 220 as much as possible while the inside of the hollow part 220 is completely filled. Since there is no step difference with the heating plate, the welding quality can be improved, and further, since the prevention sphere body 100 is also melted and welded, the fixing force of the welding surface is also improved.

덧붙여, 도 5의 예시와 같이 상기 방지구본체(100)의 테이퍼면(120)측 둘레에 걸림턱(150)을 더 형성하게 되면 상기 방지구본체(100)를 중공부(220)에 삽입할 때 위치고정하기 쉽고 편리한 장점이 있다.In addition, if the locking jaw 150 is further formed around the tapered surface 120 side of the prevention sphere body 100 as in the example of FIG. 5 , the prevention sphere body 100 can be inserted into the hollow part 220 . It has the advantage of being easy to fix and convenient.
