Title:
PENDULUM-TYPE CRADLE WHICH MAINTAINS SLEEP INDUCING OSCILLATION FREQUENCY 69
Document Type and Number:
WIPO Patent Application WO/2017/119314
Kind Code:
A1
Abstract:
A problem to be addressed by the present invention is to configure, with a simple structure, a cradle with an oscillation frequency of 69 cycles per minute which has an effect of lulling an infant to sleep. 69 oscillations per minute is the average maternal heart rate, and being a beat which is heard and felt constantly throughout gestation, is thus considered to have a sleep-inducing effect of lulling infants to sleep. First, a cradle having an oscillation frequency of 69 oscillations per minute is configured with a pendulum-type arrangement. Furthermore, effective pendulum length adjustment means are disposed for maintaining the oscillation frequency at a target level (69 oscillations per minute), said oscillation frequency fluctuating according to such factors as the weight of the infant, sheet thickness, or the weight of the cradle proper. The effective pendulum length adjustment means are means which adjust the differences in height between the center of gravity of the pendulum including a hypothetical user and the suspension fulcra of the pendulum.
