Title:
SPRING STRUT STRUCTURE FOR BED
Document Type and Number:
Japanese Patent JPS59139214
Kind Code:
A
Abstract:
The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.
