의자팔걸이용 연질몰딩재{soft molding member for chair armrest}Soft molding member for chair armrest {soft molding member for chair armrest}

본 고안은 의자팔걸이용 연질몰딩재에 관한 것으로서, 보다 상세하게는 코스트가 저렴하면서도 작업성이 우수한 새로운 구조의 의자팔걸이용 연질몰딩재에 관한 것이다.The present invention relates to a soft molding material for a chair armrest, and more particularly to a soft molding material for a chair armrest of a new structure having a low cost and excellent workability.

일반적으로 의자 팔걸이는 다양한 형상으로 제조되는데, 흔히, 원형파이프 를 절곡시켜 이루어지거나 또는 경질의 합성수지를 사출성형하여 제조된다. 그리고 의자 팔걸이에는 외관이나 사용자가 손으로 잡았을 때의 촉감 등을 고려하여 팔걸이의 상면에 PVC와 같은 연질의 합성수지로 된 장식몰딩이 부착되기도 한다. 이러한 종래의 PVC로 된 장식몰딩은 PVC수지에 가소제를 첨가하여 소정의 두께와 폭을 갖는 바아형상으로 길게 압출성형하는데, 유연성이 우수하여 자유롭게 절곡이 가능하므로, 팔걸이의 형상에 구애받지 않고 적용할 수 있는 장점이 있다.In general, chair armrests are manufactured in various shapes, and are often made by bending round pipes or by injection molding hard synthetic resin. In addition, the chair armrest may have a decorative molding made of soft synthetic resin such as PVC on the upper surface of the armrest in consideration of the appearance and the touch when the user grasps it by hand. This conventional decorative molding made of PVC is extruded into a bar shape having a predetermined thickness and width by adding a plasticizer to the PVC resin. There are advantages to it.

그런데 PVC는 비교적 가격이 저렴하고 가소제의 첨가에 따라 우수한 유연성을 갖는 다는 장점이 있기는 하나, 비중이 약 1.4정도로 상당히 크기 때문에 PVC로 성형된 몰딩재는 비교적 무게가 무거워서 유연성이 우수함에도 불구하여 작업자가 팔걸이에 부착하는 등 다루기가 쉽지 않았다.However, PVC has the advantage of being relatively inexpensive and having excellent flexibility according to the addition of plasticizer.However, since the specific gravity is about 1.4, the molding material formed of PVC is relatively heavy, so the worker has excellent flexibility. It was not easy to handle, such as attaching to an armrest

본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 가벼워서 작업성이 우수할 뿐만 아니라 원료가 절감되어 코스트가 저렴한 새로운 구성의 의자팔걸이용 연질몰딩재를 제공하고자 하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is to provide a soft molding material for a chair armrest of a new configuration that is not only light and excellent workability, but also low cost of raw materials.

본 고안에 따르면, 의자 팔걸이에 부착되는 의자팔걸이용 연질몰딩재에 있어서, 상기 몰딩재는 PVC를 발포하여 이루어진 발포심재부(10)와, PVC로 이루어져서 상기 발포심재부(10)를 감싸는 표피부(20)를 포함하며, 상기 발포심재부(10)와 표피부(20)는 일체로 압출성형된 것을 특징으로 하는 의자팔걸이용 연질몰딩재(30)가 제공된다.According to the present invention, in the soft molding material for the chair armrest attached to the chair armrest, the molding material is made of foamed PVC core member 10 and made of PVC, the skin portion surrounding the foam core member 10 ( 20), the foam core member 10 and the skin portion 20 is provided with a soft molding material 30 for chair armrests, characterized in that the extrusion molded integrally.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1과 도 2는 본 고안의 일 실시예를 보인 사시도와 단면도이고, 도 3은 그 사용상태도이다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows. 1 and 2 are a perspective view and a cross-sectional view showing an embodiment of the present invention, Figure 3 is a state diagram used.

본 고안은 의자 팔걸이에 부착되는 몰딩재(30)로서, 내부의 발포심재부(10)와, 상기 발포심재부(10)를 감싸는 표피부(20)로 이루어진다. 이러한 본 고안은 도 4에 도시된 바와 같은 압출기를 이용해 이중압출방식으로 성형된다.The present invention is a molding material (30) attached to the armrest of the chair, the inner foam core member 10, and consists of a skin portion 20 surrounding the foam core member (10). This invention is molded in a double extrusion method using an extruder as shown in FIG.

먼저, 발포심재부(10)의 원료가 되는 PVC와 기타 가소제 등의 첨가제와 더불어 발포제를 배합하여 제1호퍼(51)에 투입하고, 제2호퍼(56)에는 표피부(20)의 원료가 되는 PVC과 가소제 등의 첨가제를 배합하여 투입한다. 그리고 압출기를 작동시키면, 제1호퍼(51)에 투입된 PVC는 제1배럴(52) 내에서 가열, 용융되면서 발포제에 의해 발포되어 압출되어 발포심재부(10)를 형성한다. 그리고 상기 제2호퍼(56)에 투입된 PVC는 제2배럴(57) 내에서 가열, 용융되어 압출되는데, 이때 제2배럴(57)내의 PVC는 제1배럴(52)에서 발포압출되는 발포심재부(10)를 감싸면서 압출되어 표피부(20)를 형성한다. 이때 상기 제1배럴(52)의 압출로 상에는 냉각블록(55)이 구비된다.First, a foaming agent is mixed with an additive such as PVC and other plasticizers, which are raw materials for the foam core member 10, and the foaming agent is mixed into the first hopper 51, and the raw material of the skin portion 20 is supplied to the second hopper 56. Add and mix additives such as PVC and plasticizer. When the extruder is operated, the PVC injected into the first hopper 51 is foamed by the blowing agent while being heated and melted in the first barrel 52 to extrude to form the foam core member 10. And the PVC injected into the second hopper 56 is heated, melted and extruded in the second barrel (57), wherein the PVC in the second barrel (57) is a foam core material foam-extruded in the first barrel (52) Extruded while wrapping (10) to form the skin portion (20). At this time, the cooling block 55 is provided on the extrusion path of the first barrel 52.

이와 같이 압출성형된 몰딩재(30)는 적절한 길이로 절단되어 의자 팔걸이의 둘레면 등에 나사나 접착제 등을 사용하여 부착된다. 그리고 필요에 따라서는 표피부(20)의 둘레면에 원목무늬 등과 같은 다양한 형태의 무늬가 형성된 장식시트(32)가 부착된다.The extruded molding material 30 is cut to an appropriate length and attached to the circumferential surface of the chair armrest using a screw or an adhesive. And if necessary, the decorative sheet 32 is formed on the circumferential surface of the skin 20, the pattern of various forms such as a wooden pattern.

이상과 같이 제조되는 본 고안을 발포처리되어 표면이 울퉁불통한 압출부(10)가 표면이 매끄러운 표피부(20)에 의해 커버되므로 외관상으로는 단순히 압출성형된 종래의 몰딩재와 차이없이 매끄러운 외관을 가진다. 그러나 본 고안에 의한 몰딩재(30)는 내부가 발포처리되므로 동일한 두께와 폭을 가지는 종래의 몰딩재에 비해 전체적인 중량이 저하된다. 뿐만 아니라 동일 량의 원료를 사용하였을 때 종래의 단순히 압출된 몰딩재에 비해 생상량이 증가되어 코스트가 저하된다. 또한 본 고안은 발포심재부(10)와 표피부(20)가 동일한 수지로 이중압출되어 발포심재부(10)와 표피부(20)와 일체로 제조되므로 사용 중에 발포심재부(10)와 표피부(20)가 분리될 우려도 없다.Since the present invention manufactured as described above is foamed and covered with an uneven surface extruded portion 10 by a smooth surface portion 20, the appearance is simply smooth without any difference from the conventional molding material extruded. Has However, since the molding material 30 according to the present invention is foamed, its overall weight is lower than that of the conventional molding material having the same thickness and width. In addition, when the same amount of raw material is used, the production amount is increased compared to the conventional simply extruded molding material, thereby reducing the cost. In addition, the present invention is because the foam core member 10 and the skin portion 20 is double-extruded with the same resin and manufactured integrally with the foam core member 10 and the skin portion 20, the foam core member 10 and the table during use There is no fear that the skin 20 may be separated.

이상에서와 같이 본 고안에 의하면, 몰딩재의 내부가 발포처리되어 중량이 저하되며 원료가 절감되어 코스트가 저렴할 뿐만 아니라 종래의 몰딩재에 비해 상당히 가벼우므로 작업성도 우수한 새로운 구성의 의자팔걸이용 연질몰딩재가 제공된다.As described above, according to the present invention, the interior of the molding material is foamed, the weight is reduced, the raw material is reduced, the cost is low, and the light molding material for the chair armrest of the new configuration having excellent workability is significantly lighter than the conventional molding material Is provided.
