Protection devices for shopping carts

摘要

According to embodiments of the invention, systems, methods and devices are directed to a shopping cart with safety features which prevent or reduce the risk of injury caused to those using the cart as well as those in the vicinity of the shopping cart. A wheelbase of the shopping cart may have a set of wheels. Each wheel may have an airbag stored therein. The airbag may be deployable from any one of the wheels such the wheel is engulfed, fully or partially, within the inflated airbag. A pressure sensor may be attached to each of the wheels. The pressure sensor may constantly monitor the force being exerted in the wheel in order to identify moments when the traction may be comprised or when the cart may be at risk of toppling over. A speed or velocity sensor is attached to the wheelbase to monitor and detect for excessive speeds. The airbags may be inflatable by one or more compressed air or compressed gas cylinders or vessels.

主权项

1. A shopping cart having features to prevent injuries, comprising:
a seat attached to the shopping cart for a child; a wheelbase having a set of wheels, each wheel having an airbag stored therein such that activation of the airbags causes the corresponding wheels to be embedded inside the airbags; a pressure sensor attached to each of the wheels for monitoring the pressure of the wheels on the ground to detect any possibility of the shopping cart falling over; a speed sensor attached to the wheelbase for monitoring the velocity of the shopping cart to detect excessive speeds; and a vessel of compressed gas, wherein the gas is injectable into one or more of the airbags.
