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.

Description

[0001] For cross-references to related applications [0002] This application claims priority from Korean Patent Application 10-2013-33188 filed on March 28, 2013 and Korean Patent Application 10-2013-38366 filed on April 9, 2013, which is Korean Patent Application 10-2013-38366 Priority is claimed to Korean Patent Application No. 10-2013-33188 filed March 28, 2013, the entire contents of both patent applications being incorporated herein by reference for all purposes. technical field [0003] The present invention relates to a coil spring for a mattress having an exposed wiring portion formed on the coil spring for a mattress and working together with a spring body, to absorb external loads, and more particularly, the present invention relates to a coil spring for a mattress having means for preventing frictional noise which can Noise generated by friction between exposed wire portions and surrounding wire portions is prevented. Background technique [0004] Generally, a ...
