Description

강화유리문 테두리에 결합되는 도어 보호대 제조방법, 이것을 이용하여 제조된 도어 보호대 및 이에 의한 도어 보호대 제조용 금형 장치{A method of manufacturing a door protector coupled to a reinforced glass door frame, a door protector manufactured using the same, and a mold device for manufacturing a door protector using the same} A method of manufacturing a door protector coupled to a reinforced glass door frame, a door protector manufactured using the same, and a mold device for manufacturing a door protector using the same}

본 발명은 강화유리문 테두리에 결합되는 도어 보호대 제조방법, 이것을 이용하여 제조된 도어 보호대 및 이의 도어 보호대 제조용 금형 장치에 관한 것으로서, 더욱 상세하게는 아파트 현관도어, 강화유리도어 등과 같은 도어의 테두리에 결합되는 도어 보호대를 구성하고 있는 방풍부재와 안전부재를 단일 제품으로 제조할 수 있도록 한 강화유리문 테두리에 결합되는 도어 보호대 제조방법, 이것을 이용하여 제조된 도어 보호대 및 이에 의한 도어 보호대 제조용 금형 장치에 관한 것이다. The present invention relates to a method for manufacturing a door protector coupled to the edge of the tempered glass door, a door protector manufactured using the same, and a mold apparatus for manufacturing the door protector thereof, and more particularly, coupled to an edge of a door such as an apartment entrance door and tempered glass door. The present invention relates to a method of manufacturing a door guard coupled to an edge of a tempered glass door for manufacturing a windproof member and a safety member that constitutes a door guard, and a door protector manufactured using the same and a mold apparatus for manufacturing the door guard. .

일반적으로 강화유리문은 내부가 잘 비치고 비교적 충격에 강해 상가나 관공서, 사무실 등의 출입문의 소재로 널리 사용되고 있다.In general, tempered glass doors are well visible and relatively shock-resistant, and are widely used as materials for entrances to shops, government offices, and offices.

상기 강화유리문은 출입구의 양측 문틀 사이에 한 장의 강화유리를 적용하는 단식과, 두 장의 강화유리를 적용하는 복식으로 구분하는바, , 주로 복식으로 된 강화유리문을 선호하고 있는 실정이다.The tempered glass door is divided into single and tempered glass to apply a single sheet of tempered glass between the two sides of the door frame, it is a situation that prefers the tempered glass door mainly made of double.

상기와 같이 복식으로 된 강화유리문은 출입자가`안쪽이나 바깥쪽에서 강화유리문의 손잡이를 이용하여 밀거나 당기면서 출입한 후 놓으면, 자동으로 닫힐 수 있도록 되어 있는데, 이때 고정된 문과 회전하는 문 사이로 출입자의 부주의로 손가락 이나 손목 등에 타박상을 입히거나, 심한 경우 절단까지 되는 등 안전사고가 빈번하게 발생 되는 문제점을 갖고 있는 것이다. As above, the double tempered glass door can be closed automatically when the door is pushed or pulled by using the handle of the tempered glass door from inside or outside, and then released. The door is closed between the fixed door and the rotating door. Inadvertently injuring the finger or wrist, or even severe cutting, such as accidents are a frequent occurrence of safety problems.

따라서 이를 해결하기 위한 선행기술로는 실용신안등록 20-0279148호(참고문헌 1이라 함)에 개재된 바와 같이, 두 가지 방법으로 해결하고 있는바, 그에 따른 첫 번째는 강화유리문의 폭과 동일한 끼움브라켓트가 억지 끼움으로 결합되어 있고, 끼움브라켓트의 구멍과 지지홈에 대응하는 삽착편 및 지지편이 결합되는 완충 고무테를 조립하는 것으로 되어 있다.Therefore, as a prior art for solving this problem, as disclosed in Utility Model Registration No. 20-0279148 (refer to Reference 1), the solution is solved in two ways, the first of which is the same as the width of the tempered glass door The bracket is coupled by force fitting, and the shock absorbing rubber frame to which the insertion piece and the support piece corresponding to the hole of the fitting bracket and the support groove are assembled.

두 번째로는 강화유리문의 폭과 동일한 끼움브라켓트가 억지 끼움으로 결합되어 있고, 끼움브라켓트의 구멍과 지지홈에 대응하는 기모판과 브러쉬가 결합되는 방풍 브러쉬가 조립하는 것으로 되어 있다.Secondly, the fitting bracket equal to the width of the tempered glass door is combined by force fitting, and the windshield brush is assembled with the brush and the brush plate corresponding to the hole and the supporting groove of the fitting bracket.

상기와 같이 강화유리문의 전단 가장자리에 완충 고무테를 설치한 경우 강화유리문 틈새로 끼일 수 있는 손이나 손등의 손상 도는 것을 방지하게 되고, 방풍 브러쉬를 설치한 경우 틈새로 스며드는 외부의 미세먼지 또는 외부의 찬 공기를 차단하는 효과까지 있다.When the shock absorbing rubber frame is installed at the front edge of the tempered glass door as described above, it prevents the hand or the hand from being damaged by the gap of the tempered glass door, and when the wind brush is installed, the external fine dust or external dust penetrates into the gap It also has the effect of blocking cold air.

그러나 상기와 같이 완충 고무테와 방풍 브러쉬를 개별적 제품인 경우 제조업의 생산라인을 복수로 설치 함으로써 제품의 단가를 상승시키는 요인이 되고, 설치하는 현장에 있어서도, 완충 고무테와 방풍브러쉬를 선택적으로 설치하게 되면 어느 한 가지의 특징만을 갖게 되는 문제점이 있는 것이다.However, as described above, when the cushioning rubber frame and the windproof brush are separately manufactured, a plurality of production lines in the manufacturing industry may increase the cost of the product, and the cushioning rubber frame and the windproof brush may be selectively installed even at the installation site. If there is a problem that has only one characteristic.

따라서 이를 보완한 또 다른 선행기술은 특허등록제10-1420573호(참고문헌 2이라 함)에 개재된 바와 같이, 출입문의 테두리에 결합되는 끼움홈부와 타측부에 결합홈부를 갖는 프레임부재와 몸체부 일측에 상기 결합홈부에 끼워지는 가이드부와 타측에 방풍장착수용부를 갖는 연질의 안전부재와 상기 안전부재와 압출 성형시 하나의 금형에 의해 동시에 경질의 합성수지를 압출성형하여 상기 몸체부의 타측 부위와 일체화되는 경질의 방풍장착부와 상기 방풍장착부에 에는 한 쌍의 고정턱이 형성된 방풍부재 수용홈에 방풍부재가 삽입 장착되는 것으로 되어 있다. Therefore, another prior art that complements this, as disclosed in Patent Registration No. 10-1420573 (refer to Reference 2), the frame member and the body portion having a fitting groove portion coupled to the edge of the door and the coupling groove portion on the other side It is integrated with the other part of the body part by extruding the hard synthetic resin at the same time by one mold during extrusion molding with the safety member and the safety member having a guide portion fitted to the coupling groove portion and the wind-mounted accommodation portion on the other side The windproof member is installed in the windproof mounting portion and the windproof mounting portion in a hard windproof member accommodating groove having a pair of fixed jaws.

상기와 같이 도어 보호대는 사용자의 손을 보호하는 연질의 재질로 형성된 안전부재와, 외풍의 유입을 방지하는 방풍부재가 장착되는 경질의 재질로 형성된 방풍장착부를 하나의 금형에 동시에 압출성형하여 안전부재의 일측에 경질의 방풍장착부를 일체로 결합시킨 것으로서, 참고문헌 1과 같이 각기 다른 특징을 하나로 통일시킨 것에 있어서는 만족할 수 있는 효과가 있다As described above, the door protector is formed by a soft material protecting a user's hand and a windproof mounting part formed of a hard material equipped with a windproof member that prevents the inflow of drafts at the same time. It is a combination of the hard windshield mounting unit on one side of the, as in Reference 1, there is an effect that can be satisfied in the unification of the different features into one

그러나 상기에 있어, 안전부재와 방풍장착부가 하나의 금형에 동시에 압출성형한 성형품에 별도의 방풍부재를 조립하도록 되어 있는데, 이는 방풍장착부에 형성된 방풍부재 수용홈은 결합되는 방풍부재의 크기에 맞는 금형을 제작해야 하는 불편함이 있다. 즉, 금형을 제작할 때에 적어도 여러 번의 시행착오를 거쳐 최종 안전부재에 방풍부재가 크가가 맞는 금형을 제작한다는 점에서 금형 비용이 추가되는 문제점이 있으며, 금형을 최종 선택할 때까지 시간적 낭비가 크다 할 수 있다. However, in the above, a separate windproof member is assembled to a molded article extruded simultaneously with the safety member and the windproof mounting portion in one mold, which is formed in the windproof member receiving groove formed in the windproof fitting. There is an inconvenience to be produced. That is, there is a problem in that the mold cost is added in that a mold having a large windproof member fits into the final safety member after at least several trials and errors during the manufacture of the mold, and a large waste of time is required until the final selection of the mold. Can be.

또한, 현장의 작업자는 안전부재와 방풍장착부가 하나의 금형에 동시에 압출 성형한 성형품을 방풍부재를 일일이 조립함으로써 작업의 능룰이 저하되는 문제점까지 있는 것이다.In addition, the worker in the field has a problem that the performance rule of the work is lowered by assembling the wind-proof member by the safety member and the wind-mounted portion is molded at the same time in one mold.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서,Therefore, the present invention has been made to solve the above problems,

그 목적으로는 충격을 완화시키는 안전부재와 안전부재의 선단에 있는 방풍부재를 일체로 제조함으로써 제조업의 생산 라인이 단순화시켜 생산성 단가가 낮아짐과 더불어 안전부재와 방풍부재에 크기에 맞는 별도의 금형 비용이 필요가 없도록 하는 것을 제공함에 있다.For this purpose, by manufacturing the safety member and the windproof member at the tip of the safety member to alleviate the impact, the production line of the manufacturing industry can be simplified, resulting in a lower production cost and a separate mold cost for the safety member and the windproof member. To provide that there is no need for this.

상기 목적을 달성하기 위한 본 발명은 합성수지를 가열하여 용융시키는 용융단계(S100)에 있어서,In the present invention for achieving the above object in the melting step (S100) of melting the synthetic resin by heating,

상기 합성수시가 용융된 것을 압출을 통하여 성형된 안전부재 성형단계(S200); A safety member molding step of forming the molten synthetic resin through extrusion (S200);

상기 안전부재와 방풍부재가 밀착된 상태에서 안전부재로부터 방풍부재가 이탈을 방지하는 안전부재와 방풍부재 결합단계(S400)를 포함하는 도어 보호대의 제조 방법의 특징이 있다.In the state in which the safety member and the windproof member is in close contact there is a feature of the manufacturing method of the door guard including a safety member and a windproof member coupling step (S400) to prevent the separation of the windproof member from the safety member.
