This press release is a dream shared by businesses that empathize with the April Dream project and aim to make April 1st a day overflowing with dreams, to be realized in the future.
Nakanishi Sangyo Co., Ltd. (Location: Chiyoda-ku, Tokyo; Representative Director: Junji Kimoto) supports April Dream, a project that aims to make April 1st a day for announcing dreams. This press release is Nakanishi Sangyo's dream.
## We want to protect the safety and smiles of people across Japan with small architectural hardware.
Architectural hardware may not be a prominent feature in homes.
However, the safe use of windows and doors, and the ability to live each day with peace of mind, are supported by each small piece of hardware.
That is why we continue to develop products by repeatedly asking ourselves, "Can this hardware reduce anxiety?" and "Can we make homes safer?"
Within our homes, there are anxieties we haven't yet noticed.
Accidents can be triggered by things we use every day.
We believe that addressing these anxieties and giving them form is our role as an architectural hardware manufacturer, and it leads to protecting safety and smiles.
## Mamorunrun®
One such initiative is "Mamorunrun®," a window lock developed to prevent children from falling accidents.
Among accidents in homes, falls from windows or balconies can happen in an instant, even if you look away for just a moment.
Child accidents, in particular, are said to increase from around 1-2 years old when they start walking and their range of activity expands, and are most common around 3-4 years old when they can do more things themselves.
Children grow faster than adults realize, and accidents occur when they reach places where adults thought, "They can't reach yet," or "They can't open it yet."
That is why we believed that products are needed to prepare for accidents before they happen, not after.
Mamorunrun® is a double lock that engages automatically with normal locking, despite its simple operation.
Its key feature, which is difficult to notice at first glance, is a crescent lock with a child lock structure, featuring a knob with an exquisite weight that makes it difficult for children to operate.
Safety can be enhanced with a little ingenuity.
We developed it believing that such a small precaution leads to great peace of mind.
## Nakanishi Sangyo's Mission
Even small architectural hardware can save lives.
Even small improvements can reduce anxiety.
We will continue to focus on the unseen dangers in daily life and develop products that support safe living environments.
To support daily life with architectural hardware, increase the number of safe homes, and spread days filled with smiles across Japan.
That is our dream.
We are seriously committed to realizing this dream.
"April Dream" is a project by PR TIMES where companies announce dreams they hope to achieve on April 1st. We are seriously aiming to realize this dream.
