Bed Mattress Spring Structure for Noise-Free Vertical Support

A guide member is introduced as an intermediary component between the connection end portion and the uppermost winding. This guide member prevents direct contact between these parts, eliminating frictional noise while maintaining the compact structure. The guide member acts as a mediator that allows vertical movement without permitting lateral contact.

The harmful frictional contact function is extracted from the spring system by separating the connection end portion from direct interaction with the uppermost winding. The guide member isolates the connection end portion, allowing it to maintain its position without experiencing harmful contacts during operation.

The guide member serves as a mediator that permits vertical movement of the exposure wire spring while preventing lateral displacement. It provides a guided path that maintains the spring's vertical alignment, ensuring uniform cushioning while preserving operational freedom within defined constraints.

The guide member changes the movement parameters of the exposure wire spring by allowing motion only in the vertical direction while constraining lateral movement. This selective parameter control maintains cushioning effectiveness by ensuring the spring moves only along its intended axis.

The guide member provides localized structural support at the connection end portion without affecting the overall flexibility of the exposure wire spring. By reinforcing only the specific area where lateral displacement occurs, the spring maintains its rigidity where needed while preserving its cushioning softness in the loading area.

The spring system is segmented into functional zones: the guide member provides rigid guidance at the connection end, while the exposure wire spring itself maintains its flexible, cushioning properties in the loading zone. This spatial segmentation allows different parts to have different mechanical properties optimized for their specific functions.
