본 실시예의 타이어(10)는 외피(11)와, 외피(11) 내부에 채워진 발포수지(12)로 구성된다. 외피(11)는 "U"자 형태이다. 외피(11)의 일측은 개방되어 있다. 외피(11)의 말단부(113)는 바퀴의 림(rim)에 결합된다. 외피(11)에는 트레드(tread, 111)가 돌출되어 있다. 외피(11)의 말단부(113)의 내부에는 와이어(112)가 삽입되어 있다. 와이어(112)는 말단부(113)의 형태가 유지되도록 말단부(113)를 지지한다. 외피(11)는 고무재질일 수 있다. 종래 기술에서는 외피(11)만으로 공기압 타이어가 완성될 수 있다. 외피(11) 내부에는 나일론 재질의 직물(14)이 부착되어 있을 수 있다.The tire 10 of this embodiment is composed of a shell 11 and a foamed resin 12 filled in the shell 11. The outer shell 11 is in the form of a "U". One side of the shell 11 is open. The distal end 113 of the shell 11 is coupled to the rim of the wheel. A tread 111 protrudes from the shell 11. The wire 112 is inserted into the distal end 113 of the shell 11. The wire 112 supports the distal end 113 so that the shape of the distal end 113 is maintained. Outer shell 11 may be a rubber material. In the prior art, the pneumatic tire can be completed only by the shell 11. The outer fabric 11 may be attached to the fabric 14 made of nylon.
외피(11) 내부에는 발포수지(12, formed resin)가 채워져 있다. 발포수지(12)는 수지(resin)를 발포(forming)하여 형성할 수 있다. 발포수지(12)는 발포제가 함유된 수지원료에 열을 가함으로써 형성될 수 있다. 수지원료는 페이스트(paste) 상태일 수 있다. 발포수지(12)는 천연고무(natural rubber), 합성고무(synthetic rubber) 또는 합성수지(synthetic resin) 등의 재질일 수 있다. 발포수지(12)는 발포가 되는 재료이면 어떤 것이라도 사용될 수 있다.  The outer shell 11 is filled with a foamed resin (12, formed resin). The foamed resin 12 may be formed by foaming a resin. The foamed resin 12 may be formed by applying heat to a water support material containing a blowing agent. The support fee may be in a paste state. The foamed resin 12 may be made of a natural rubber, synthetic rubber, synthetic resin, or the like. The foamed resin 12 may be used as long as the foamed material is a material.
합성고무로는 스티렌부타디엔고무(styrene butadien rubber:SBR),폴리클로로프렌고무(polychloroprene rubber:CR),니트릴고무(acrylonitrilebutadiene rubber:NBR),부틸고무(isoprene-isobutylene rubber:IIR),부타디엔고무(butadiene rubber:BR),이소프렌고무(isoprene rubber:IR),에틸렌프로필렌고무(ethylene propylene rubber:EPR),다황화물계고무(polysulfide rubber),플루오로고무(fluororubber),아크릴고무(acrylic rubber) 등이 사용될 수 있다.Synthetic rubbers include styrene butadien rubber (SBR), polychloroprene rubber (CR), nitrile rubber (acrylonitrilebutadiene rubber (NBR), isoprene-isobutylene rubber (IIR), butadiene rubber (butadiene rubber) : BR), isoprene rubber (IR), ethylene propylene rubber (EPR), polysulfide rubber, fluororubber, acrylic rubber, etc. have.
외부로 노출된 발포수지(12)에는 결합홈(13)이 형성되어 있다. 결합홈(13)은 링 형태일 수 있다. 결합홈(13)은 외부로 노출된다. 결합홈(13)은 외피(11)의 말단부(113)에 인접하여 위치한다. 도 3의 단면도와 같이, 결합홈(13)은 외부에서 내부로 깊어질수록 단면의 폭이 좁아진다. 따라서, 타이어(10)의 외부가 눌려질 경우, 외피(11)의 말단부(113)가 외부로 벌어진다. 도 4와 같이, 외부의 힘이 외피(11)에 전달될 경우 결합홈(13)이 눌려진다. 그 결과, 도 4와 같이 림(100)의 내측벽에 외피(11)의 말단부(113)가 밀착된다. 따라서, 주행중에 타이어(10)가 림(100)으로부터 이탈되지 않는다.Coupling grooves 13 are formed in the foamed resin 12 exposed to the outside. Coupling groove 13 may be in the form of a ring. Coupling groove 13 is exposed to the outside. Coupling groove 13 is located adjacent to the distal end 113 of the shell (11). As shown in the cross-sectional view of Figure 3, the coupling groove 13 becomes narrower in width as the cross section is deeper from the outside to the inside. Therefore, when the outside of the tire 10 is pressed, the distal end 113 of the shell 11 opens to the outside. As shown in Figure 4, when the external force is transmitted to the shell 11, the coupling groove 13 is pressed. As a result, the distal end 113 of the shell 11 is in close contact with the inner wall of the rim 100 as shown in FIG. Thus, the tire 10 is not separated from the rim 100 while traveling.
결합홈(13)의 측면에는 지지부(121)가 형성되어 있다. 지지부(121)는 발포수지(12)의 일부가 돌출되어 형성된다. 도 4와 같이 타이어(10)가 눌려질 경우, 지지부(121)는 외부 힘을 림(100)에 전달한다. 결합홈(13)은 타이어(10)의 전 구간에 링 형태로 형성될 수 있다. 또한, 결합홈(13)은 타이어(10)의 일부구간에만 형성될 수도 있다.The support part 121 is formed at the side of the coupling groove 13. The support part 121 is formed by protruding a part of the foamed resin 12. When the tire 10 is pressed as shown in FIG. 4, the support 121 transmits an external force to the rim 100. Coupling groove 13 may be formed in a ring shape in the entire section of the tire (10). In addition, the coupling groove 13 may be formed only in a section of the tire 10.
결합홈(13)으로 인하여, 림(100, rim)에 타이어(10)를 쉽게 결합할 수 있다. 또한, 다양한 폭의 림(100, rim)에 타이어(10)를 결합할 수 있다. 도 5는 림(100)에 타이어(10)를 결합하는 과정을 보여주는 도면이다. Due to the coupling groove 13, the tire 10 can be easily coupled to the rim 100. In addition, the tire 10 may be coupled to rims 100 of various widths. 5 is a view illustrating a process of coupling the tire 10 to the rim 100.
만약, 결합홈(13) 내부에도 발포수지가 모두 채워진다면, 외피(11)의 말단부(113)는 변형될 공간이 없다. 그러나 본 실시예의 타이어(10)는 결합홈(13)이 도 5의 (b)와 같이 변형된다. 따라서, 말단부(113)가 변형되어 쉽게 림(100)에 결합된다. 이후, 발포수지(12)의 복원력으로 말단부(113)는 도 5의 (c)와 같이 림(100)의 내벽에 밀착된다. 또한, 결합홈(13)으로 인하여 다양한 폭의 림(100)에도 결합될 수 있다. 림(100)의 내측 폭은 15mm~20mm 정도이다.If all of the foaming resin is filled in the coupling groove 13, the distal end 113 of the shell 11 has no space to be deformed. However, in the tire 10 of the present embodiment, the coupling groove 13 is modified as shown in FIG. Thus, the distal end 113 is deformed and easily coupled to the rim 100. Then, the distal end 113 is in close contact with the inner wall of the rim 100 as shown in Figure 5 (c) by the restoring force of the foamed resin (12). In addition, the coupling groove 13 may be coupled to the rim 100 of various widths. The inner width of the rim 100 is about 15mm-20mm.
한편, 외피(11)의 말단부(113)의 내부에는 와이어(112)가 삽입되어 있다. 와이어(112)는 말단부(113)의 형태가 변형되지 않도록 지지한다. 와이어(112)는 금속재질 일 수 있다. 와이어(112)가 너무 강하면 말단부(113)가 잘 늘어나지 않는다. 이렇게 되면, 말단부(113)를 림(100)에 쉽게 결합할 수 없다. 도 6은 타이어(10)의 측면 투시도이다. 본 실시예의 와이어(112)는 일부구간이 절단되어 있다. 따라서, 절단된 부분에서 말단부(113)는 신축성이 있다. 따라서, 말단부(113)는 절단부(1121)에서 잘 늘어난다. 따라서, 말단부(113)를 늘려 도 5와 같이, 타이어(10)를 림(100)에 쉽게 결합한다. 절단부(1121)는 한 곳 이상 형성될 수 있다.On the other hand, a wire 112 is inserted into the distal end 113 of the outer shell 11. The wire 112 supports the shape of the distal end 113 not to be deformed. The wire 112 may be made of metal. If the wire 112 is too strong, the distal end 113 does not stretch well. In this case, the distal end 113 cannot be easily coupled to the rim 100. 6 is a side perspective view of the tire 10. A portion of the wire 112 of the present embodiment is cut. Therefore, the distal end portion 113 is elastic in the cut portion. Thus, the distal end portion 113 extends well at the cut portion 1121. Therefore, by extending the distal end 113, as shown in Figure 5, the tire 10 is easily coupled to the rim 100. One or more cut portions 1121 may be formed.
와이어(112)는 금속 재질로 이루어질 수 있다. 와이어(112)는 굴곡된 형상일 수도 있다. 한편, 와이어(112)는 탄성력 있는 합성수지 재질일 수도 있다.The wire 112 may be made of a metal material. The wire 112 may be curved. On the other hand, the wire 112 may be a synthetic resin material with elasticity.
도 7은 본 발명의 제2 실시예에 따른 타이어의 단면도이다. 도 8은 본 발명의 제2 실시예에 따른 타이어에 결합된 와이어의 평면도이다.7 is a sectional view of a tire according to a second embodiment of the present invention. 8 is a plan view of a wire coupled to a tire according to a second embodiment of the present invention.
타이어(20)는 외피(21)와, 외피(21) 내부에 채워진 발포수지(22)로 구성된다. 외피(21)는 "U"자 형태이다. 외피(21)의 일측은 개방되어 있다. 외피(21)의 말단부(213)는 바퀴의 림(rim)에 결합된다. 외피(21)에는 트레드(tread, 211)가 돌출되어 있다. 외피(21)의 말단부(213)의 내부에는 와이어(212)가 삽입되어 있다. 와이어(212)는 말단부(213)의 형태를 유지하도록 지지한다. 외피(21)는 고무재질일 수 있다. The tire 20 is composed of an outer shell 21 and a foamed resin 22 filled in the outer shell 21. The outer shell 21 is in the form of a "U". One side of the shell 21 is open. The distal end 213 of the sheath 21 is coupled to the rim of the wheel. A tread 211 protrudes from the outer shell 21. The wire 212 is inserted into the distal end portion 213 of the outer shell 21. Wire 212 supports to maintain the shape of distal end 213. The outer shell 21 may be made of rubber.
발포수지(22)에는 결합홈(23)이 형성되어 있다. 결합홈(23)에 의해 말단부(213)가 유연해질 수 있다. 결합홈(23)에 의해 말단부(213)가 쉽게 변형될 수 있다. 따라서, 타이어(20)를 림(rim)에 쉽게 결합할 수 있다. 또한, 결합홈(23)에 의해 타이어(20)를 림(rim)에서 쉽게 분리할 수도 있다. 결합홈(23)은 링 형태로 발포수지(22)의 전 영역에 형성될 수 있다. 결합홈(23)은 발포수지(22)의 일부 영역에만 형성될 수도 있다.Coupling grooves 23 are formed in the foamed resin 22. The distal end portion 213 may be flexible by the coupling groove 23. The distal end portion 213 can be easily deformed by the coupling groove 23. Thus, the tire 20 can be easily coupled to the rim. In addition, the tire 20 may be easily separated from the rim by the coupling groove 23. The coupling groove 23 may be formed in the entire area of the foamed resin 22 in the form of a ring. The coupling groove 23 may be formed only in a portion of the foamed resin 22.
한편, 외부 힘이 타이어(20)에 전달되면, 결합홈(23)이 눌려져 형태가 변형된다. 결합홈(23)이 과도하게 눌려지는 것을 방지하기 위하여, 결합홈(23)의 바닥면에는 돌기부(25)가 형성되어 있다. 돌기부(25)가 결합홈(23)의 바닥면이 림에 닿는 것을 방지한다. 돌기부(25)는 결합홈(23)이 과도하게 눌려져서 변형되는 것을 방지한다.On the other hand, when the external force is transmitted to the tire 20, the coupling groove 23 is pressed to deform the shape. In order to prevent the coupling groove 23 from being excessively pressed, the protrusion 25 is formed on the bottom surface of the coupling groove 23. The protrusion 25 prevents the bottom surface of the coupling groove 23 from touching the rim. The protrusion 25 prevents the coupling groove 23 from being excessively deformed and deformed.
외피(21)의 말단부(213)에는 와이어(212)가 삽입되어 있다. 와이어(212)는 도 8과 같이 굴곡된(waved) 형상이다. 와이어(212)는 일부 영역만 굴곡될 수 있다. 평상시에는 와이어(212)가 말단부(213)의 형태가 유지되도록 말단부(213)를 지지한다. 그러나 강한 힘으로 말단부(213)를 잡아당길 경우, 굴곡된 와이어(212)가 펴지면서 말단부(213)가 늘어날 수 있도록 한다. 굴곡된 와이어(212)에 의해서 말단부(213)를 림(rim)에 쉽게 결합할 수 있다.The wire 212 is inserted into the distal end portion 213 of the outer shell 21. The wire 212 has a waved shape as shown in FIG. 8. The wire 212 may be curved only in some areas. Usually, the wire 212 supports the distal end 213 so that the shape of the distal end 213 is maintained. However, when pulling the distal end 213 with a strong force, the bent wire 212 is extended so that the distal end 213 can be stretched. The bent wire 212 allows the distal end 213 to be easily coupled to the rim.
한편, 와이어는 탄성력있는 재질의 합성수지일 수 있다. 예를들어, 나일론 재질로 와이어를 만들 수 있다. 이러한 나일론 와이어는 평상시에는 말단부(213)의형태를 유지한다. 말단부(213)를 강하게 잡아당기면, 나일론 와이어가 조금 늘어나, 림과 말단부(213)가 쉽게 결합할 수 있게 된다. 와이어가 합성수지 섬유일 경우 일부구간이 절단되지 않을 수 있다. 또한, 와이어가 합성수지 섬유일 경우 절곡된 구간이 없을 수도 있다.On the other hand, the wire may be a synthetic resin of elastic material. For example, a wire can be made of nylon. This nylon wire normally maintains the shape of the distal end portion 213. When the end portion 213 is strongly pulled, the nylon wire is stretched slightly, so that the rim and the end portion 213 can be easily coupled. If the wire is a synthetic fiber, some sections may not be cut. In addition, when the wire is a synthetic fiber, there may be no bent section.
도 9는 본 발명의 제3 실시예에 따른 타이어의 단면도이다. 본 실시예의 타이어(30)는, 외피(31)와, 외피(31) 내부에 채워진 발포수지(32)를 포함한다. 외부로 노출된 발포수지(32)에는 결합홈(33)이 형성되어 있다. 결합홈(33)의 바닥면에는 바닥홀(35)이 형성되어 있다. 바닥홀(35)은 결합홈(33)의 바닥면에 링 형태로 연속적으로 형성될 수 있다. 또한, 바닥홀(35)은 등간격으로 결합홈(33)의 바닥면의 일부 영역에만 형성될 수도 있다. 바닥홀(35)은 타이어(30)의 무게를 줄여준다. 또한, 바닥홀(35)은 말단부(313)가 쉽게 변형할 수 있도록 한다. 9 is a sectional view of a tire according to a third embodiment of the present invention. The tire 30 of the present embodiment includes an outer shell 31 and a foamed resin 32 filled in the outer shell 31. Coupling grooves 33 are formed in the foamed resin 32 exposed to the outside. The bottom hole 35 is formed on the bottom surface of the coupling groove 33. The bottom hole 35 may be continuously formed in a ring shape on the bottom surface of the coupling groove 33. In addition, the bottom hole 35 may be formed only in a partial region of the bottom surface of the coupling groove 33 at equal intervals. The bottom hole 35 reduces the weight of the tire 30. In addition, the bottom hole 35 allows the distal end portion 313 to be easily deformed.
도 10은 본 발명의 제4 실시예에 따른 바퀴의 분리 단면도이다. 도 11은 본 발명의 제4 실시예에 따른 바퀴의 단면도이다. 본 실시예의 바퀴(40)는 타이어와 림(45)의 결합으로 구성된다. 10 is an exploded cross-sectional view of a wheel according to a fourth exemplary embodiment of the present invention. 11 is a cross-sectional view of a wheel according to a fourth embodiment of the present invention. Wheel 40 of the present embodiment is composed of a combination of the tire and the rim (45).
타이어는 외피(41)와, 외피(41) 내부에 채워진 발포수지(42)로 구성된다. 외피(41)는 "U"자 형태이다. 외피(41)의 일측은 개방되어 있다. 외피(41)의 말단부(413)는 림(45, rim)에 결합된다. 외피(41)에는 트레드(tread, 411)가 돌출되어 있다. 외피(41)의 말단부(413)의 내부에는 와이어(412)가 삽입되어 있다. 와이어(412)는 말단부(413)의 과도한 변형을 방지한다. 와이어(412)는 말단부(413)의 형태를 지지한다. 외피(41)는 고무재질일 수 있다. 외피(41)는 종래의 공기압 타이어를 그대로 사용할 수 있다.The tire is composed of a sheath 41 and a foamed resin 42 filled in the sheath 41. The sheath 41 is in the form of a "U". One side of the outer shell 41 is open. The distal end 413 of the sheath 41 is coupled to the rim 45. A tread 411 protrudes from the outer shell 41. A wire 412 is inserted into the distal end portion 413 of the outer shell 41. Wire 412 prevents excessive deformation of distal end 413. Wire 412 supports the shape of distal end 413. The sheath 41 may be made of rubber. The outer shell 41 can use a conventional pneumatic tire as it is.
발포수지(22)에는 결합홈(43)이 형성되어 있다. 결합홈(43)에 의해 형성된 여유공간으로 말단부(413)는 좌우로 유동하며 움직일 수 있다. 결합홈(43)에 의해 말단부(413)의 변형이 자유롭다. 따라서, 말단부(413)를 림(45, rim)에 쉽게 결합할 수 있다. 또한, 말단부(413)를 림(45, rim)으로부터 쉽게 분리할 수도 있다. Coupling grooves 43 are formed in the foamed resin 22. The distal end portion 413 may move to the left and right to the free space formed by the coupling groove 43. Deformation of the distal end portion 413 by the coupling groove 43 is free. Thus, the distal end 413 can be easily coupled to the rim 45. The distal end 413 can also be easily separated from the rim 45.
도 11과 같이, 말단부(413)가 림(45)에 결합된다. 결합홈(43)의 주변에 있는 지지부(421)는 외피(41)에 눌려진 외부 힘을 림(45)에 전달한다. 종래 타이어는 공기압으로 외부 힘을 림에 전달하였다. 본 실시예의 바퀴(40)는 공기압이 없으므로, 구조체로서 외부 힘을 림에 전달해야 한다. As shown in FIG. 11, the distal end 413 is coupled to the rim 45. Support 421 in the periphery of the coupling groove 43 transmits the external force pressed by the outer shell 41 to the rim (45). Conventional tires transmit external forces to the rim by air pressure. Since the wheel 40 of the present embodiment has no air pressure, the external force must be transmitted to the rim as a structure.
본 실시예의 바퀴(40)는 결합홈(43)과 상기 림(45) 사이의 공기압이 대기압과 동일하다. 따라서, 본 실시예의 바퀴(40)는 펑크가 없다. 뾰족한 물체가 결합홈(43)을 관통하더라도, 펑크가 나지 않는다. In the wheel 40 of the present embodiment, the air pressure between the coupling groove 43 and the rim 45 is equal to the atmospheric pressure. Therefore, the wheel 40 of the present embodiment is not punctured. Even if a pointed object penetrates through the coupling groove 43, no puncture occurs.
한편, 외피(41)의 말단부(413)의 외측폭(d1)은 림(45)의 내측폭(d2)보다 크다. 따라서, 말단부(413)를 결합홈(43) 방향으로 구부려서 림(45)에 결합하여야 한다. 이후, 발포수지(42)의 복원력에 의해서 말단부(413)는 림(45)의 내측벽에 밀착된다. 따라서, 말단부(413)가 림(45)으로부터 이탈되지 않는다.On the other hand, the outer width d1 of the distal end portion 413 of the outer shell 41 is larger than the inner width d2 of the rim 45. Therefore, the distal end portion 413 should be bent in the direction of the coupling groove 43 to be coupled to the rim 45. Thereafter, the distal end portion 413 is in close contact with the inner wall of the rim 45 by the restoring force of the foamed resin 42. Thus, the distal end 413 does not leave the rim 45.

The tire manufacturing apparatus 50 of this embodiment includes a ring member 51 having an outer surface 5111 and a ring-shaped protruding member 52 protruding from the outer surface 5111. As shown in Fig. 14 (side view), the ring member 51 includes a ring body portion 511 in which an opening portion A is formed; It includes a detachable member 512 coupled to the opening (A).
돌출부재(52)는 완벽한 링 형태일 수도 있다. 또한, 돌출부재(52)의 일부구간은 끊어져 있을 수도 있다. 돌출부재(52)는 일부구간에서 끊어져도 '링 형태'로 간주한다. The protruding member 52 may be in the form of a perfect ring. In addition, some sections of the protruding member 52 may be cut off. The protruding member 52 is regarded as a 'ring shape' even if broken in some section.

The first side wall 513 and the second side wall 514 serve as stoppers so that the distal end of the shell no longer expands to the outside during the foaming process. The first side wall 513 and the second side wall 514 support the distal end portion of the outer shell during the foaming process.
도 12와 같이, 타이어(1000)를 제조할 때는 링 몸체부(511)와 착탈부재(512)가 결합되어 있다. 이후, 타이어(1000)가 완성되면, 타이어(1000)를 타이어 제조장치(50)로부터 분리해야 한다. 그러나 돌출부재(52), 제1 측면벽(513) 및 제2 측면벽(514)에 의해서 타이어 제조장치(50)에서 타이어(1000)를 분리하기가 쉽지 않다. 따라서, 도 14와 같이, 링 몸체부(511)에서 착탈부재(512)를 분리한다. 이렇게 되면 개방부(A)가 노출되고 공간이 확보된다. 이후, 타이어(1000)를 타이어 제조장치(50)로부터 쉽게 분리할 수 있게 된다.As shown in Figure 12, when manufacturing the tire 1000, the ring body portion 511 and the detachable member 512 is coupled. Thereafter, when the tire 1000 is completed, the tire 1000 should be separated from the tire manufacturing apparatus 50. However, it is not easy to separate the tire 1000 from the tire manufacturing apparatus 50 by the protruding member 52, the first side wall 513, and the second side wall 514. Therefore, as illustrated in FIG. 14, the detachable member 512 is separated from the ring body 511. In this case, the opening A is exposed and space is secured. Thereafter, the tire 1000 may be easily separated from the tire manufacturing apparatus 50.

S11은 외부면이 형성된 링부재(51)와; 상기 외부면의 중심부에 돌출된 링 형태의 돌출부재(52)를 포함하는 타이어 제조장치(50)를 준비하는 단계이다. 본 실시예의 타이어 제조장치(50)는 도 12 내지 도 14에서 설명한 타이어 제조장치(50)와 동일한 구성이다. 본 실시예의 타이어 제조방법은 타이어 제조장치(50)를 이용하여 타이어(60)를 제조하는 방법을 설명한다. S11 and the ring member 51 the outer surface is formed; A step of preparing a tire manufacturing apparatus 50 including a ring-shaped protruding member 52 protruding from the center of the outer surface. The tire manufacturing apparatus 50 of this embodiment is the same structure as the tire manufacturing apparatus 50 demonstrated in FIGS. 12-14. The tire manufacturing method of the present embodiment describes a method of manufacturing the tire 60 by using the tire manufacturing apparatus 50.
돌출부재(52)는 완벽한 링 형태일 수도 있다. 또한, 돌출부재(52)의 일부구간은 끊어져 있을 수도 있다. 일부구간이 끊어져도 '링 형태'로 간주한다. The protruding member 52 may be in the form of a perfect ring. In addition, some sections of the protruding member 52 may be cut off. Even if some sections are broken, they are considered as 'ring'.
S12는 단면의 형상이 "U"인 외피(61)를 준비하는 단계이다. 외피(61)는 일반적인 공기압 타이어와 동일한 형태일 수 있다. 외피(61)의 단면 형상은 "U"이다. S11 단계와 S12 단계는 순서를 바꾸어도 상관없다. 외피(61)에는 공기홀(air hole)이 형성되어 있을 수 있다. 추후, 발포수지 원료(621)가 발포되면서, 외피(61) 내부의 공기는 공기홀(air hole)을 통하여 외부로 배출된다. 공기홀(air hole)은 육안으로 관찰되지 않을 만큼 작을 수 있다. 또한, 공기홀은 외피(61)에 복수로 형성될 수 있다. 공기홀은 외피(61)에 송곳 등을 이용하여 뚫을 수 있다. S12 is a step of preparing the outer cover 61 having the shape of the cross section "U". Outer shell 61 may have the same shape as a general pneumatic tire. The cross-sectional shape of the shell 61 is "U". The steps S11 and S12 may be reversed. The outer shell 61 may have an air hole formed therein. Subsequently, as the foamed resin raw material 621 is foamed, the air inside the shell 61 is discharged to the outside through an air hole. Air holes can be small enough to not be observed with the naked eye. In addition, a plurality of air holes may be formed in the outer shell 61. The air hole can be drilled in the outer shell 61 using an awl or the like.
S13은 상기 외피(61)와 타이어 제조장치(50) 사이에 발포제가 함유된 발포수지 원료(621)를 삽입하는 단계이다. 발포수지 원료(621)는 수지(resin)와 발포제가 혼합되어 구성된다. 이러한 수지로는 천연수지, 합성수지, 합성고무일 수 있다. 발포제에 열이 가해지면 기포가 발생하여 발포수지 원료(621)를 팽창시킨다. 도 16과 같이, 외피(61)와 타이어 제조장치(50)가 결합된다. 링부재(51)의 측면벽이 외피(61)의 말단부를 고정한다. 외피(61)의 내부 공간에는 발포수지 원료(621)가 위치한다. 발포수지 원료(621)는 페이스트(paste)상태이다. 발포수지 원료(621)에는 발포제가 포함되어 있다. 발포수지 원료(621)에는 여러 종류의 합성고무 또는 합성수지가 혼합되어 있을 수 있다.S13 is a step of inserting a foaming resin raw material 621 containing a blowing agent between the outer shell 61 and the tire manufacturing apparatus 50. The foamed resin raw material 621 is composed of a resin and a foaming agent mixed. Such resins may be natural resins, synthetic resins, synthetic rubbers. When heat is applied to the blowing agent, bubbles are generated to expand the foamed resin raw material 621. As shown in Figure 16, the outer shell 61 and the tire manufacturing apparatus 50 is combined. The side wall of the ring member 51 fixes the distal end of the shell 61. The foamed resin raw material 621 is located in the inner space of the outer shell 61. The foamed resin raw material 621 is in a paste state. The foaming resin raw material 621 contains a foaming agent. The foamed resin raw material 621 may be mixed with various kinds of synthetic rubber or synthetic resin.
S14는 열을 가하여, 상기 발포수지 원료(621)를 발포함으로써 상기 외피(61) 내부가 발포수지(622)로 채워진 타이어(60)를 제조하는 단계이다. 발포제에 열을 가하면 기포가 생성된다. 이 기포는 발포수지 원료(621)를 팽창시킨다. 따라서, 도 17과 같이, 발포수지(622)가 외피(61) 내부에 채워진다. 발포수지(622)의 팽창압력이 외피(61)를 팽창시킨다. 외피(61) 내부에 존재하는 공기는 외피(61)에 형성된 복수의 공기홀을 통하여 외부로 방출된다. 따라서, 외피(61) 내부는 발포수지(622)로 모두 채워진다.S14 is a step of manufacturing the tire 60 filled with the foamed resin 622 inside the outer shell 61 by foaming the foamed resin raw material 621 by applying heat. Heat is applied to the blowing agent to create bubbles. This bubble expands the foamed resin raw material 621. Therefore, as shown in FIG. 17, the foamed resin 622 is filled in the shell 61. The expansion pressure of the foamed resin 622 expands the shell 61. Air existing in the outer shell 61 is discharged to the outside through a plurality of air holes formed in the outer shell 61. Therefore, the inside of the outer shell 61 is filled with all foamed resin 622.
S15는 상기 타이어(60)를 상기 타이어 제조장치(50)로부터 분리하는 단계이다. 본 실시예의 타이어(60)는 마치 고압의 공기가 들어있는 것과 같이, 발포수지(622)가 외피(61) 내부에 팽창되어 채워져 있다. 따라서, 타이어 제조장치(50)에서 타이어(60)를 분리하기가 용이하지 않다. 특히, 돌출부재(52) 때문에 타이어(60)를 링부재(51)로부터 분리하기가 용이하지 않다. 또한, 링부재(51)에 형성된 측면벽 때문에, 타이어(60)를 링부재(51)로부터 분리하기 어렵다.S15 is a step of separating the tire 60 from the tire manufacturing apparatus 50. In the tire 60 of this embodiment, the foamed resin 622 is expanded and filled inside the shell 61, as if high pressure air is contained therein. Therefore, it is not easy to separate the tire 60 from the tire manufacturing device 50. In particular, it is not easy to separate the tire 60 from the ring member 51 because of the protruding member 52. In addition, because of the side walls formed in the ring member 51, it is difficult to separate the tire 60 from the ring member 51.
본 실시예의 링부재(51)는 도 14와 같이, 개방부(A)가 형성된 링 몸체부(511)와; 상기 개방부(A)에 결합되는 착탈부재(512)를 포함한다. 도 14와 같이, 착탈부재(512)를 링 몸체부(511)로부터 분리하여 개방부(A)를 노출시킨다. 이후, 개방부(A)의 여유공간을 이용하여 타이어를 링 몸체부(511)로부터 쉽게 분리할 수 있다. Ring member 51 of the present embodiment, as shown in Figure 14, the ring body portion 511 is formed with an opening (A); It includes a detachable member 512 coupled to the opening (A). As shown in FIG. 14, the detachable member 512 is separated from the ring body 511 to expose the opening A. FIG. Thereafter, the tire can be easily separated from the ring body 511 using the free space of the opening A. FIG.

Then, when heat is applied to the cover sheet 294 in step S55, the cover sheet 294 is heat-sealed to the distal end portion 2911 of the shell 291. Thermal fusion means melting and bonding of materials by heat.
이와 같이, 외피(291)의 말단부(2911)에 절단부(293)를 형성한다. 이 절단부(293)에서 말단부(2911)가 5mm~10mm 정도 늘어난다. 따라서, 외피(291)의 말단부(2911)를 늘려서 바퀴의 림에 쉽게 결합시킬 수 있다. 절단부(293)은 일부구간에만 형성되어 있기 때문에, 와이어(292)는 전체적인 외피(291)의 말단부의 형태를 유지할 수 있도록 한다. As such, the cut portion 293 is formed at the distal end 2911 of the shell 291. In this cutout portion 293, the distal end portion 2911 extends about 5 mm to 10 mm. Accordingly, the distal end portion 2911 of the shell 291 can be extended to easily engage the rim of the wheel. Since the cut portion 293 is formed only in a portion, the wire 292 can maintain the shape of the distal end portion of the overall shell 291.
오토바이 타이어와 같이, 두꺼운 외피(291)로 구성된 타이어는 림에 외피(291)를 결합시키기가 용이하지 않다. 그러나, 본 실시예와 같이, 와이어(292)에 절단부(293)가 일부 형성되면 림에 외피를 결합하기가 용이하다.Like motorcycle tires, a tire composed of thick skin 291 is not easy to couple the skin 291 to the rim. However, as shown in the present embodiment, when the cut portion 293 is partially formed on the wire 292, it is easy to couple the shell to the rim.
절단부(293)에 커버시트(294)를 부착하지 않을 수도 있다. 커버시트(294)는 미관상 부착되는 부재이다.The cover sheet 294 may not be attached to the cut portion 293. The cover sheet 294 is a member that is aesthetically attached.

S61 is a step of inserting the expansion member 332 which couples the outer shell material 333 to the outside between the first mold 3311 and the second mold 3312. The first mold 3311 and the second mold 3312 are molds generally used in the process of manufacturing the outer shell 334. When the first mold 3311 and the second mold 3312 are combined, a ring shape space is formed. The cross section of the first mold 3311 and the cross section of the second mold 3312 may each have a semicircular shape. Air may be injected into the expansion member 332. When air is injected, the expansion member 332 is expanded. The expansion member 332 is in the form of a ring. Wires may be inserted at the edges of the outer shell material 333. The outer shell material 333 may be combined with a nylon fabric.

S62는 상기 팽창부재(332)를 팽창시켜, 상기 외피 원료(333)를 상기 제1 몰드(3311)와 상기 제2 몰드(3312)의 내벽에 밀착시킴으로써, 개방부가 형성된 외피(334)를 제조하는 단계이다. 도 45와 같이, 팽창부재(332)를 팽창시키면, 외피 원료(333)가 제1 몰드(3311)와 제2 몰드(3312)의 벽면에 밀착된다. 이 상태에서 열을 가하면 외피 원료(333)가 경화되어 외피(334)가 완성된다. 이러한 외피(334)를 종래에는 림(rim)에 결합하여 타이어로 사용하였다. 그러나 본 발명의 경우 외피(334) 내부에 발포수지(3352)를 채워넣어, 타이어(330)를 완성한다. 외피 원료(333)는 고무 재질일 수 있다. S62 단계에서 열을 가하면, 외피(334)의 성형이 잘 된다.S62 expands the expansion member 332 to closely contact the inner shell material 333 with the inner walls of the first mold 3311 and the second mold 3312 to manufacture the outer shell 334 having the opening portion formed therein. Step. As shown in FIG. 45, when the expansion member 332 is inflated, the shell material 333 is in close contact with the wall surfaces of the first mold 3311 and the second mold 3312. When heat is applied in this state, the outer shell material 333 is cured to complete the outer shell 334. This envelope 334 is conventionally used as a tire by coupling to a rim. However, in the case of the present invention, the foamed resin 3332 is filled in the outer shell 334 to complete the tire 330. The outer shell material 333 may be a rubber material. When the heat is applied in step S62, the shell 334 is well formed.
도면에는 도시되지 않았으나, 제1 몰드(3311)와 제2 몰드(3312)의 결합부에서 외피 원료(333)의 말단부가 고정될 수 있다. 또한, 몰드(3311,3312)의 내벽에는 홈이 형성되어 있다. 이러한 홈에 의해서 외피(334)에는 트레드가 형성된다. Although not shown in the drawings, the distal end portion of the outer shell material 333 may be fixed at the coupling portion of the first mold 3311 and the second mold 3312. In addition, grooves are formed in the inner walls of the molds 3311 and 3312. The tread is formed in the shell 334 by the groove.
S63은 상기 팽창부재(332)를 상기 외피(334)로부터 분리하는 단계이다. 제1 몰드(3311)와 제2 몰드(3312)를 일부분 개방한다. 외피(334)로부터 팽창부재(332)를 분리한다. 팽창부재(332)는 다른 외피를 제조할 때 다시 사용할 수 있다. 팽창부재(332)와 외피(334)를 모두 몰드(3311,3312)로부터 이탈시킨 뒤, 팽창부재(332)를 외피(334)로부터 분리할 수도 있다. 또한, 몰드(3311,3312)를 일부분 개방한 뒤에, 팽창부재(332)를 외피(334)로부터 분리할 수도 있다.S63 is a step of separating the expansion member 332 from the shell 334. The first mold 3311 and the second mold 3312 are partially opened. The expansion member 332 is separated from the outer shell 334. The expansion member 332 can be used again when manufacturing other shells. After the expansion member 332 and the outer shell 334 are both released from the molds 3311 and 3312, the expansion member 332 may be separated from the outer shell 334. In addition, after partially opening the molds 3311 and 3312, the expansion member 332 may be separated from the shell 334.
S64는 상기 외피(334) 내부에 발포수지 원료(3351)를 삽입하고, 상기 외피(334)의 상기 개방부에 링 형태의 돌출부재(336)를 위치시키는 단계이다. 팽창부재(332)를 외피(334)로부터 분리한다. 이후, 도 46과 같이 외피(334) 내부에 발포수지 원료(3351)를 삽입한다. 이후, 외피(334)의 개방부에 돌출부재(336)를 위치시킨다. 돌출부재(336)는 합성고무, 합성수지, 천연수지, 플랙시블한 금속 등 다양한 재질로 만들어질 수 있다.S64 is a step of inserting the foamed resin raw material 3331 into the shell 334, and positioning the ring-shaped protruding member 336 in the opening of the shell 334. The expansion member 332 is separated from the shell 334. Thereafter, the foamed resin raw material 3331 is inserted into the shell 334 as shown in FIG. 46. Thereafter, the protruding member 336 is positioned at the opening of the shell 334. The protruding member 336 may be made of various materials such as synthetic rubber, synthetic resin, natural resin, and flexible metal.
돌출부재(336)는 일부영역만 플랙시블할 수도 있다. 또한, 돌출부재(336)는 실온에서는 딱딱하나, 열이 가해진 상태에서만 플랙시블할 수도 있다. The protruding member 336 may flex only a partial region. In addition, the protruding member 336 is hard at room temperature, but may be flexible only when heat is applied.
발포수지 원료(3351)는 합성수지, 합성고무, 천연고무 등일 수 있다. 발포수지 원료(3351)에는 발포제가 포함되어 있다.The foamed resin raw material 3331 may be synthetic resin, synthetic rubber, natural rubber, or the like. The foaming resin raw material 3331 contains a foaming agent.
돌출부재(336)는 섭씨 100도에서 섭씨 300도에서 형체를 유지한다. 즉, 돌출부재(336))는 내열성을 갖추고 있다. 발포수지 원료(3351)를 발포하는 과정에서 섭씨 150도 정도의 열이 가해진다. 이때, 돌출부재(336)는 이러한 열에 형태를 유지할 수 있는 것이 좋다. 돌출부재(336)는 내열성 소재로 만들어질 수 있다. 돌출부재(336)는 실온에서는 딱딱하나, 열이 가해지면 플랙시블할 수 있다. 돌출부재(336)는 일부 영역만 플랙시블할 수도 있다. The protruding member 336 maintains the shape at 300 degrees Celsius at 100 degrees Celsius. That is, the protruding member 336 has heat resistance. Heat of about 150 degrees Celsius is applied in the process of foaming the foamed resin raw material 3331. At this time, the protruding member 336 is preferably able to maintain the shape in this column. The protruding member 336 may be made of a heat resistant material. The protruding member 336 is hard at room temperature, but may be flexible when heat is applied. The protruding member 336 may be flexible only in some areas.
돌출부재(336)는 몇 개의 부분으로 분리할 수 있는 구조일 수 있다. 이 경우 돌출부재(336)는 플랙시블하지 않아도 된다. 돌출부재(336)는 금속재질로서, 2개 이상으로 분할된 구조일 수 있다. 돌출부재(336)는 몇 개의 조각으로 분할되어 경첩으로 결합될 수 있다.Protruding member 336 may be a structure that can be separated into several parts.

The protruding member 336 may be divided into several pieces and joined by a hinge.
S65는 열을 가하여 상기 발포수지 원료(3351)를 발포시킴으로써, 상기 외피(334) 내부에 발포수지(3352)를 채우는 단계이다. 도 47과 같이 발포수지 원료(3351)가 발포되면, 외피(334) 내부에 발포수지(3352)가 채워진다. 돌출부재(336)로 인하여, 발포수지(3352)에는 도 50과 같이 결합홈(337)이 형성된다. 도 50의 결합홈(337)에 의해서 타이어(330)를 다양한 폭의 림(rim)에 용이하게 착탈할 수 있다.S65 is a step of filling the foamed resin 3332 inside the outer shell 334 by foaming the foamed resin raw material 3331 by applying heat. When the foamed resin raw material 3331 is foamed as shown in FIG. 47, the foamed resin 3332 is filled in the outer shell 334. Due to the protruding member 336, the foamed resin 3332 is formed with a coupling groove 337 as shown in FIG. The coupling groove 337 of FIG. 50 can easily attach and detach the tire 330 to rims of various widths.
한편, S63 단계와 S65 단계 사이에, 외피(334)에 공기홀(air hole)을 형성하는 단계를 더 진행할 수 있다. 발포수지 원료(3351)가 팽창할 경우, 외피(334) 내부의 공기가 외부로 배출되어야 한다. 송곳과 같은 뾰족한 물체를 이용하여 외피(334)에 복수의 홀을 미세하게 형성할 수 있다. S65단계(발포공정)를 진행하면 외피(334) 내부의 공기가 공기홀(air hole)을 통하여 외부로 배출된다.On the other hand, between the step S63 and S65, the step of forming an air hole (air hole) in the shell 334 can be further proceeded. When the foamed resin raw material 3331 expands, the air inside the shell 334 should be discharged to the outside. A plurality of holes may be minutely formed in the shell 334 by using a sharp object such as an awl. Proceeding to step S65 (foaming step), the air inside the shell 334 is discharged to the outside through the air hole (air hole).
S66은 상기 제1 몰드(3311)와 상기 제2 몰드(3312)를 상기 외피(334)로부터 분리는 단계이다. 도 47의 화살표와 같이, 제1 몰드(3311)와 제2 몰드(3312)를 분리할 수 있다. 그 결과 도 48과 같이 외피(334)가 외부로 노출된다.S66 is a step of separating the first mold 3311 and the second mold 3312 from the shell 334. As illustrated by the arrow of FIG. 47, the first mold 3311 and the second mold 3312 may be separated. As a result, the outer shell 334 is exposed to the outside as shown in FIG.
S67은 상기 돌출부재(336)를 상기 발포수지(3352)로부터 분리하는 단계이다. 도 49의 측면도와 같이, 유연한(flexible) 재질의 돌출부재(336)를 발포수지(3352)로부터 분리할 수 있다. 그 결과 도 50과 같은 타이어(330)가 완성된다. 돌출부재(336)는 실온(room temperature)에서는 딱딱할 수 있으나, 열을 가하면 플랙시블한 상태를 유지할 수 있다. 따라서, 돌출부재(336)는 열이 가해진 상태에서 쉽게 발포수지(3352)로부터 분리할 수 있다. S67 is a step of separating the protruding member 336 from the foamed resin 3332. As shown in the side view of FIG. 49, the protruding member 336 made of a flexible material may be separated from the foamed resin 3332. As a result, the tire 330 as shown in FIG. 50 is completed. The protruding member 336 may be hard at room temperature, but may remain flexible when heat is applied. Accordingly, the protruding member 336 can be easily separated from the foamed resin 3332 in the state where heat is applied.
돌출부재(336)는 여러 조각으로 분할될 수 있는 구조일 수 있다. 이런 경우, S67단계는 돌출부재(336)를 여러 조각으로 분할하여, 타이어(330)로부터 분리할 수 있다. 여기서 "여러 조각으로 분할이 가능하다"의 의미는 2 조각 이상으로 분할할 수 있다는 것을 의미한다. 돌출부재(336)는 실온에서는 딱딱하나, 열이 가해지면 플랙시블할 수도 있다. 또한, 돌출부재(336)는 일부영역만 플랙시블할 수도 있다.Protruding member 336 may be a structure that can be divided into several pieces. In this case, step S67 may divide the protruding member 336 into several pieces to separate from the tire 330. Here, "dividable into multiple pieces" means that it can be divided into two or more pieces. The protruding member 336 is hard at room temperature, but may be flexible when heat is applied. In addition, the protruding member 336 may be flexible only in a partial region.

S82 단계는 열을 가하면서 진행될 수 있다.S82 expands the expansion member 632 to bring the shell material 633 into close contact with the inner walls of the first mold 6311 and the second mold 6312, thereby forming an outer shell and an tread 6321. 634 is a step of preparing. As shown in FIG. 63, when the expansion member 632 is inflated, the shell material 633 is in close contact with the wall surfaces of the first mold 6311 and the second mold 6312. When heat is applied in this state, the outer shell material 633 is cured to complete the outer shell 634. This shell 634 is conventionally used as a pneumatic tire by coupling to a rim. However, in the case of the present invention, the foam 6352 is filled in the shell 634 to complete the tire 630. The outer shell material 633 may be a rubber material. Step S82 may proceed while applying heat.
외피(634)의 말단부는 몰드(6311, 6312)와 팽창부재(632)에 의해서 고정된다. 몰드(6311, 6312)의 내측에는 도 62와 같이 트레드 홈(tread groove, 63111,63121)이 형성되어 있다. 트레드 홈(tread groove, 63111,63121)에 외피 원료(633)가 채워져, 외피(634)에는 트레드(6341)가 형성된다.End portions of the outer shell 634 are fixed by the molds 6311 and 6312 and the expansion member 632.

Shell 634 is separated from molds 6311 and 6312. The expansion member 632 is separated from the shell 634. The expansion member 632 can be used again when manufacturing other envelopes.
S84는 상기 외피(634) 내부에 발포수지 원료(6351)를 삽입하고, 상기 외피(634)의 개방부에 링 형태의 돌출부재(636)를 위치시키는 단계이다. S84 is a step of inserting the foamed resin raw material (6351) in the shell 634, the positioning of the ring-shaped protruding member 636 in the opening of the shell (634).
도 64와 같이 외피(634) 내부에 발포수지 원료(6351)를 삽입한다. 이후, 외피(634)의 개방부에 플랙시블(flexible)한 재질의 돌출부재(636)를 위치시킨다. 돌출부재(636)는 합성고무, 합성수지, 천연수지, 플랙시블한 금속 등 다양한 재질로 만들어질 수 있다. 돌출부재(636)는 링 형태이다.As shown in FIG. 64, the foamed resin raw material 6321 is inserted into the shell 634. Thereafter, the protruding member 636 made of a flexible material is positioned at the opening of the outer shell 634. The protruding member 636 may be made of various materials such as synthetic rubber, synthetic resin, natural resin, and flexible metal. The protruding member 636 is in the form of a ring.
발포수지 원료(6351)는 합성수지, 합성고무, 천연고무 등일 수 있다. 발포수지 원료(6351)에는 발포제가 포함되어 있다.The foamed resin raw material 6321 may be synthetic resin, synthetic rubber, natural rubber, or the like. The foaming resin raw material 6321 contains a blowing agent.
링 형태의 돌출부재(636)는 섭씨 100도에서 섭씨 300도에서 형체를 유지할 수 있다. 즉, 돌출부재(636)는 내열성을 갖추고 있다. 발포수지 원료(3351)를 발포하는 과정에서 섭씨 150도 정도의 열이 가해진다. 이때, 돌출부재(636)는 이러한 열에 형태를 유지할 수 있는 것이 좋다. 돌출부재(636)는 내열성 소재로 만들어질 수 있다. 한편, 돌출부재(636)는 실온에서는 딱딱하나, 열이 가해지면 유연해질 수도 있다. 또한, 돌출부재(636)는 일부영역만 플랙시블할 수도 있다.The ring-shaped protruding member 636 may maintain a shape at 300 degrees Celsius at 100 degrees Celsius. That is, the protruding member 636 has heat resistance. Heat of about 150 degrees Celsius is applied in the process of foaming the foamed resin raw material 3331. At this time, the protruding member 636 may be able to maintain the shape in this column. The protruding member 636 may be made of a heat resistant material. On the other hand, the protruding member 636 is hard at room temperature, but may be flexible when heat is applied. In addition, the protruding member 636 may be flexible only in a partial region.
한편, 돌출부재(636)는 몇 개의 부분으로 분리할 수 있는 구조일 수 있다. 이 경우 돌출부재(636)는 플랙시블하지 않아도 된다. 즉, 돌출부재(636)는 금속재질로서, 2개 이상으로 분할된 구조일 수 있다. 돌출부재(636)는 몇 개의 조각으로 분할되어 경첩으로 결합될 수 있다.On the other hand, the protruding member 636 may be a structure that can be separated into several parts. In this case, the protruding member 636 does not have to be flexible. That is, the protruding member 636 may be a metal material and have a structure divided into two or more. The protruding member 636 may be divided into several pieces and joined by a hinge.
S85는 제3 몰드(6313)와 제4 몰드(6314)의 결합으로 형성된 링 형태의 제2 내부공간(6382)에 상기 외피(634)를 삽입하는 단계이다. 이때, 제2 내부공간(6382)은 내부공간(6381)보다 크다. 제1 내부공간(6381)은 도 62(단면도)와 같이 제1 몰드(6311)와 제2 몰드(6312)의 결합으로 형성된 공간이다. S85 단계의 외피(634) 내부에는 발포수지 원료(6351)와 돌출부재(636)가 결합되어 있다.S85 is a step of inserting the shell 634 into the ring-shaped second inner space 6652 formed by the combination of the third mold 6313 and the fourth mold 6314. At this time, the second internal space 6602 is larger than the internal space 6601. The first internal space 6601 is a space formed by combining the first mold 6311 and the second mold 6312 as shown in FIG. 62 (sectional view). Inside the outer shell 634 of step S85 is a foamed resin raw material 6321 and the protruding member 636 is coupled.
이와 같이, 제2 내부공간(6382)이 제1 내부공간(6381)보다 크면, 외피(634)를 삽입하기가 용이하다. 아울러, 이미 형성된 트레드(6341)가 공정 중에 몰드(6313, 6314)의 내벽에 닿지않아 손상되지 않는다. 따라서, 불량율이 낮은 타이어(630)를 생산할 수 있다.As such, when the second inner space 6652 is larger than the first inner space 6641, it is easy to insert the shell 634. In addition, the tread 6321 already formed does not touch the inner walls of the molds 6313 and 6314 and is not damaged during the process. Therefore, the tire 630 having a low defective rate can be produced.
S86은 열을 가하여 상기 발포수지 원료(6351)를 발포시킴으로써, 상기 외피(634) 내부에 발포수지(6352)를 채우는 단계이다. 도 65와 같이 발포수지 원료(6351)가 발포되면, 외피(634) 내부에 발포수지(6352)가 채워진다. 돌출부재(636)로 인하여, 발포수지(6352)에는 결합홈(637)이 형성된다. 도 68의 결합홈(637)에 의해서 타이어(630)를 다양한 폭의 림(rim)에 용이하게 착탈할 수 있다.S86 is foaming the foamed resin raw material (6351) by applying heat, thereby filling the foamed resin (6352) inside the shell (634). When the foamed resin raw material 6321 is foamed as shown in FIG. 65, the foamed resin 6352 is filled in the shell 634. Due to the protruding member 636, the foaming resin 6352 is formed with a coupling groove 637. The coupling groove 637 of FIG. 68 allows the tire 630 to be easily attached and detached to rims of various widths.
한편, S83 단계와 S86 단계 사이에, 외피(634)에 공기홀(air hole)을 형성하는 단계를 더 진행할 수 있다. 발포수지 원료(6351)가 팽창할 경우, 외피(634) 내부의 공기가 외부로 배출되어야 한다. 송곳과 같은 뾰족한 물체를 이용하여 외피(634)에 복수의 홀을 미세하게 형성할 수 있다. S85단계(발포공정)를 진행하면 외피(634) 내부의 공기가 공기홀(air hole)을 통하여 외부로 배출된다.On the other hand, between the step S83 and S86, the step of forming an air hole (air hole) in the shell 634 can be further proceeded. When the foamed resin raw material 6321 expands, the air inside the shell 634 should be discharged to the outside. A plurality of holes may be minutely formed in the shell 634 by using a sharp object such as an awl. Proceeding to step S85 (foaming process), the air inside the shell 634 is discharged to the outside through an air hole.
S87은 상기 제3 몰드(6313)와 상기 제4 몰드(6314)를 상기 외피(634)로부터 분리는 단계이다. 그 결과 도 66과 같이 외피(634)가 외부로 노출된다.S87 is a step of separating the third mold 6313 and the fourth mold 6314 from the shell 634. As a result, the outer shell 634 is exposed to the outside as shown in FIG.
S88은 상기 돌출부재(636)를 상기 발포수지(6352)로부터 분리하는 단계이다. 도 67의 측면도와 같이, 유연한(flexible) 재질의 돌출부재(636)를 발포수지(6352)로부터 분리할 수 있다. 그 결과 도 68과 같은 타이어(630)가 완성된다. S88 is a step of separating the protruding member 636 from the foamed resin 6632. As shown in the side view of FIG. 67, the protruding member 636 made of a flexible material may be separated from the foamed resin 6352. As a result, the tire 630 as shown in FIG. 68 is completed.
돌출부재(636)가 금속과 같이 딱딱한 재질일 경우, 여러 조각으로 분할될 수 있는 구조일 수 있다. 이런 경우, S87단계는 돌출부재(636)를 여러 조각으로 분할하여, 타이어(630)로부터 분리할 수 있다. 여기서 "여러 조각으로 분할이 가능하다"의 의미는 2 조각 이상으로 분할할 수 있다는 것을 의미한다.If the protruding member 636 is a hard material such as metal, it may be a structure that can be divided into pieces. In this case, step S87 may divide the protruding member 636 into several pieces and separate it from the tire 630. Here, "dividable into multiple pieces" means that it can be divided into two or more pieces.
