Description

The present invention relates to a nursing room unit and a server.

When a mother with a baby breastfeeds or changes diapers while on the go, use a bed placed in a dedicated space (for example, a nursing room) on the go (for example, a shopping mall). Some such beds have the function of measuring body weight.

For example, Patent Document 1 discloses a technique for detecting a load of a subject on a bed.

Japanese Unexamined Patent Publication No. 2018-061908

When the mother breastfeeds, sit on the sofa.
On the other hand, when the mother changes diapers, the baby is placed in the crib.
However, since the seating surface of the crib is higher than the seating surface of the sofa, it is difficult for the mother to sit down for breastfeeding. In other words, it is difficult for a crib to be used for both breastfeeding and changing diapers.
Therefore, in the technique of Patent Document 1, it is possible to measure the weight of the baby on the bed while changing diapers, but the technique cannot be used for the purpose of breastfeeding.

In order to achieve both the purpose of breastfeeding and changing diapers in the nursing room, it is necessary to place both a sofa and a bed.
However, since sufficient space is not secured in the nursing room, the effective space of the nursing room is significantly reduced when both the sofa and the bed are arranged. As a result, the comfort of the nursing room is impaired.

An object of the present invention is to secure a sufficient effective space for a dedicated space (for example, a nursing room) for breastfeeding and changing diapers, and to provide a comfortable environment for breastfeeding and changing diapers.

One aspect of the present invention is
A sofa bed that can form a sofa form and a bed form,
With a backrest in the sofa form,
The backrest forms the bed seating surface in the bed form and
A weight measuring sensor for measuring the weight of a person to be measured on the bed seat surface is provided.
It is a sofa bed.
