  • Publication number: 20220232992
    Abstract: 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.

  • Publication number: 20150084251
    Abstract: A high tension coil spring for a bed mattress having an exposed wiring portion which is formed on the coil spring and works together with a body spring to absorb an external load. A gap A is provided on at least one of upper and lower end wiring portions 14 and 14? so as to define a space in which at least one of turns 16-5 and 16-5? of upper and lower exposed wiring portions 16 and 16? moves upward and downward while the coil spring is being compressed. Frictional noise between the upper and lower end wiring portions and the upper and lower turns 16-5 and 16-5? of upper and lower exposed wiring portions 16 and 16? is fundamentally prevented. The elasticity of the upper and lower exposed wiring portions is increased. The wiring portions move only upward and downward without being displaced or deformed in the lateral direction, thereby increasing longevity.

  • Publication number: 20140291906
    Abstract: A coil spring for a bed mattress. At least one of contact wiring portions 16-5 and 16-5? of the upper and lower exposed wiring portions 16 and 16? which abut to the end wiring portions 14 while the upper and lower exposed wiring portion 16, 16? are being compressed has a contact surface A which is in contact with one corresponding end wiring portion of the end wiring portions 14, whereby frictional noise between the exposed wiring portion 16, 16? and the end wiring portion 14 is prevented. It is possible to consequently remove friction that is created due to contact between the exposed wiring portion and the end wiring portion while the exposed portion is being compressed, thereby preventing noise. The exposed wiring portion and the body wiring portion move only upward and downward without being displaced or deformed in the lateral direction, thereby increasing longevity.

  • Publication number: 20120091644
    Abstract: Disclosed herein is a pocket spring structure for a bed mattress, in which a rigid support capable of resisting compressive strength due to applied load is further integrally formed in a partial region of a spring mounted in a sealed pocket, thereby preventing deformation of the spring and increasing its durability. That is, the present invention provides a pocket spring structure for a bed mattress, in which a separate rigid support capable of resisting compressive strength due to applied load is integrally formed in a partial region of a spring mounted in a pocket formed of fabric to prevent deformation of the spring, even when large and small loads are irregularly and repeatedly concentrated on the spring, thereby increasing its durability and further improving the quality of the bed mattress.

  • Patent number: 8109490
    Abstract: Disclosed herein is a spring structure having a contact-preventing and rigidity-reinforcing function for a bed mattress in which the structure of a connection end portion for connecting a body spring and an exposure wire spring to each other is improved such that the connection end portion is not in close contact with an uppermost winding and/or a lowermost winding of the body spring and such that when a load is exerted to an exposure wire spring a displacement is prevented from being generated in which the exposure wire spring is leaned to one side, and rigidity of the spring is reinforced so that the exposure wire spring ascends/descends vertically only, thereby easily preventing the lateral displacement and deformation of the spring along with a prevention of a noise due to a frictional contact to prolong the lifespan of the spring.
