Description

The present invention relates to a sofa bed .

When a mother with an infant goes out and wants to breastfeed or change the baby's diaper, she uses a bed located in a special space (e.g., a nursing room) at the destination (e.g., a shopping mall). Some of these beds have a function for measuring the baby's weight.

For example, Patent Document 1 discloses technology for detecting the weight of a subject on a bed.

JP 2018-061908 A

If the mother is breastfeeding, she sits on the sofa.
On the other hand, when the mother changes the diaper, she places the baby in the crib.
However, the seat of a baby bed is higher than that of a sofa, making it difficult for a mother to sit down on it to breastfeed. In other words, it is difficult to use a baby bed for both breastfeeding and changing diapers.
Therefore, although the technology of Patent Document 1 makes it possible to measure the weight of an infant on a bed while changing the infant's diaper, the technology cannot be used for the purpose of breastfeeding.

In order to achieve both the purpose of breastfeeding and diaper changing in a nursing room, it is necessary to provide both a sofa and a bed.
However, since there is not enough space in the nursing room, arranging both the sofa and the bed significantly reduces the effective space of the nursing room, which results in a loss of comfort in the nursing room.

The object of the present invention is to ensure sufficient usable space for a dedicated space for breastfeeding and diaper changing (e.g., a breastfeeding room) and to provide a comfortable environment for breastfeeding and diaper changing.

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

The process in FIG. 9 is triggered, for example, by the user U placing the measurement subject T on the second surface (bed seat surface) 26b, as shown in FIG. 10.

The sofa bed 20 detects the bed configuration (S120).
Specifically, when the backrest 26 satisfies a predetermined condition, the processor 22 changes the weight measuring sensor 25 to a measurement-enabled state. The predetermined condition is, for example, at least one of the following:
The rotation angle of the backrest 26 reaches a predetermined angle (for example, the XY plane of the backrest 26 is horizontal). The rotation of the backrest 26 stops.

After step S120, the sofa bed 20 performs measurement (S121).
Specifically, a body weight model is stored in the storage device 21. The body weight model describes the correlation between the load applied by the subject T to the second surface (bed seat surface) 26b and the body weight of the subject T.
The weight measuring sensor 25 measures the load of the measurement subject T supported by the second surface (bed seat surface) 26b.

Specifically, the processor 32 identifies the measurement result information database (FIG. 8) associated with the measurement subject identification information included in the history display request data transmitted in step S111.
The processor 32 identifies records from the measurement result information database that satisfy a specified condition (e.g., all records, or records that correspond to measurement date and time information for a specified period (e.g., three months) going back from the execution date and time of step S131).
The processor 32 refers to the user information database (FIG. 7) to identify the measurement subject name information associated with the measurement subject identification information.

After step S131, the server 30 executes a history display response (S132).
Specifically, the processor 32 transmits history display response data to the client device 10. The history display response data includes the following information.
Information on the record identified in step S131 Name information of the measurement subject identified in step S131
