Document Type and Number:
WIPO Patent Application WO/2015/199048
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a pushcart capable of preventing a fall without an increase in overall weight.
A pushcart of the present invention issues a warning on the basis of a first weight outside the interval of a front wheel shaft and a rear wheel shaft as viewed in a vertical direction, and a predetermined weight. For example, the predetermined weight is the weight bearing on a mounting portion disposed in the interval of the front wheel shaft and the rear wheel shaft as viewed in the vertical direction. When the first weight is greater than the predetermined weight, an alert unit issues the warning in the form of sound, light, and the like so as to make a user recognize the danger of a fall. As a result, the pushcart of the present invention can prevent a fall. Specifically, the alert unit calculates the center of gravity position of the cart on the basis of the first weight and the predetermined weight, and issues the warning when the calculated center of gravity position is outside the interval of the first wheel shaft and the second wheel shaft as viewed in the vertical direction.
