Description

A diaper exchanging table

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaper changer, and more particularly, to a diaper changer that improves convenience, safety, and hygiene so that a baby can easily wear a diaper.

In order to improve the childcare environment in recent years, the related laws have been amended in 2007, and it has become mandatory for infants and toddlers to be installed in women's toilets of public facilities such as public parks and public buildings. It also has a breastfeeding space for infants and toddlers, The break room was installed separately.

Especially, since 2010, it has been obligatory to install a diaper changer in public toilets. However, there are many public toilets that do not have a diaper changer.

Korean Patent No. 10-1199802, Korean Patent No. 10-1240394, Korean Patent Laid-Open No. 10-2015-0013021 and the like relate to the diaper changer.

However, the technique disclosed in this document can not safely support the infant when the diaper is exchanged, and the upper body support can not be adjusted so as to conform to the body shape of the infant, so that there is a risk that the infant may fall off from the diaper exchange during the change of the diaper.

In addition, since the material of the diaper changer is not an eco-friendly material, it has hygiene problems such as exposure to environmental hormones.
