[0019]Various aspects of the present invention provide a coil spring for a bed mattress having means for preventing frictional noise which can prevent the noise that is created due to th

Problems solved by technology

First, as shown in FIG. 3, in the process in which the coil spring 10 is compressed at the moment that the bed mattress is subjected to a load, a contact wiring portion 16-5 of the exposed wiring portion 16 abuts to the end wiring portion 14 which is positioned below while moving down. This consequently creates noise due to contact between the exposed wiring portion 16 and the end wiring portion 14.
Second, when a large load is applied to the bed mattress, the exposed wiring portion 16 of the spring assembly is compressed

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

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priorities from Korean Patent Application Number 10-2013-33188 filed on Mar. 28 2013 and Korean Patent Application Number 10-2013-38366 filed on Apr. 9, 2013, claiming priority from Korean Patent Application Number 10-2013-33188 filed on Mar. 28 2013, the entire contents of which are incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a coil spring for a bed mattress having an exposed wiring portion which is formed on the coil spring for a bed mattress and works together with a spring body to absorb an external load, and more particularly, to a coil spring for a bed mattress having means for preventing frictional noise which can prevent the noise that is created by the friction between an exposed wiring portion and a surrounding wiring portion while the exposed wiring portion is being compressed.[0004]2.
