用于床垫的具有防摩擦噪声器件的高张力螺旋弹簧结构
摘要：
一种用于床垫的高张力螺旋弹簧结构，包括弹簧主体和外露绕线部分，它们吸收外加载荷。在主体绕线部分(12)的上端和/或下端绕线部分(14、14’)中的至少一个上形成直径增大部分(A)，并且直径增大部分提供了上部和/或下部外露开始绕线部分(16‑5、16‑5’)上下移动的空间。在主体绕线部分(12)和上、下外露绕线部分(16、16’)中的至少一个上形成刚性支承端(18)，并且其吸收压缩载荷。螺旋弹簧结构的直径增大部分和刚性端基本上防止了当外露绕线部分被压缩时由外露绕线部分与周围的绕线部分之间的摩擦所产生的噪声，并且显著地增加了外露绕线部分的弹性。
摘要（英）：

A high tension coil spring structure for a bed mattress includes spring bodies and exposed wiring portions which absorb an external load. Diameter-increasing portions (A) are formed on at least one of upper and/or lower end wiring portions (14, 14') of body wiring portions (12), and provide spaces in which upper and/or lower exposure start wiring portions (16-5, 16-5') move upward and downward. Rigid support ends (18) are formed on at least one of the body wiring portions (12) and upper and lower exposed wiring portions (16, 16'), and absorb a compressive load. The diameter-increasing portions and the rigid ends of the coil spring structure fundamentally prevent noise caused by friction between the exposed wiring portions and surrounding wiring portions when the exposed wiring portions are compressed and significantly increase the elasticity of the exposed wiring portions.
