BRAKING APPARATUS AND WARNING TRIANGLE DEPLOYING THE BRAKING APPARATUS

A self-applying braking apparatus to prevent wind-blown movement of a mobile device includes a main body, a resisting member, a retaining member, a pushing member, and a mounting member. The braking apparatus is mounted on an application device by the mounting member. The retaining member provides an elastic force to fix the main body on the application device. The resisting member is disposed on the main body and configured to abut the tarmac or ground to prevent the mobile device from moving. The pushing member is disposed on the main body and is configured to push the resisting member to abut the ground when blown by the wind or by turbulence from a passing vehicle in a predetermined direction, when greater than the elastic force. The braking apparatus prevents unwanted wind-blown movement.
