매트리스의 제조 방법 {Method for manufacturing a matress}Method for manufacturing a mattress {Method for manufacturing a matress}

본 발명은 침대틀의 몸체상면에 탑재되어 쿠션력을 제공하는 매트리스에 관한 것으로, 특히 매트리스의 전체 높이를 완충부재의 두께에 해당하는 만큼 증대하여 쿠션감을 향상시킴과 더불어 취급 및 관리에 따른 편리성을 제공시킬 수 있도록 된 매트리스의 제조 방법에 관한 것이다.The present invention relates to a mattress mounted on the top of the body of the bed frame to provide a cushioning force, in particular to increase the overall height of the mattress by the thickness of the cushioning member to improve the feeling of cushioning and convenience in handling and management It relates to a manufacturing method of the mattress that can be provided.

일반적으로, 매트리스는, 침대틀의 상부측에 탑재되는 직육면체 형상으로 성형된 쿠션부재로서, 이 매트리스는 강선태에 종횡방향을 향해 연속적으로 설치된 스프링틀과, 스프링틀의 상하면에 각각의 쿠션재를 통해 설치된 상하부커버 및, 스프링틀의 둘레면에 설치된 측면커버로 구성된다.In general, a mattress is a cushion member formed into a rectangular parallelepiped shape mounted on an upper side of a bed frame, and the mattress is provided with a spring frame continuously installed in a longitudinal direction in the longitudinal direction and through respective cushioning materials on the upper and lower surfaces of the spring frame. The upper and lower cover is installed, and the side cover is installed on the circumferential surface of the spring frame.

따라서, 매트리스의 제조과정에서, 스프링틀의 상하면에 각각의 쿠션재를 개재한 상태에서, 상하부커버와 측면커버를 맞대고 별도의 봉합커버로 감싸면서 재봉하면, 스프링틀의 탄성력 및 쿠션재와 상하부커버의 쿠션감에 의해 취침자에게 안락함을 제공하게 되는 것이다.Therefore, in the manufacturing process of the mattress, while sewing the upper and lower cover and the side cover with each other in the state of interposing the cushioning material on the upper and lower surfaces, while sewing with a separate sealing cover, the elasticity of the spring frame and the cushioning material and the upper and lower cover cushion The senses provide comfort to the sleeping person.

그런데, 매트리스들은 스프링틀의 탄성력의 한계 및 구조적인 특성 등으로 인하여 그 전체 높이를 마냥 무한정으로 두껍게 형성할 수 없는 상태이므로, 예컨대 한 개의 매트리스를 이용하여 쿠션력을 증대하거나 또는 안락함을 제공하기에는 미흡한 문제점이 있었다.However, since the mattresses cannot be formed indefinitely thick as the entire height due to the limitations of the spring force and the structural characteristics, it is insufficient to increase the cushioning force or provide comfort using, for example, one mattress. There was a problem.
