Abstract: A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a support member, a mounting member, and a resilient member. The support member is coupled to the main body. The mounting member is movably mounted to the support member. The rollers are mounted to the mounting member and the main body. The resilient member elastically resists the support member and the mounting member to bias the mounting member. When the support member is subjected to a downward force, the support member abuts against a ground to keep the bracket stationary.

Abstract: A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a rotating mechanism and a stopping member coupled to the rotating mechanism. The rotating mechanism is rotationally coupled to the main body. One of the rollers is mounted adjacent to the stopping member. When the rotating mechanism is rotated, the stopping member is engaged with a ground to prevent the bracket from moving.

Abstract: An omnidirectional wheel includes a hub, a number of wheels, and a number of rubber covers. The hub defines a shaft hole passing through the hub. Each of the wheels is rotationally mounted on the hub and spaced around the shaft hole. Each of the rubber covers is sleeved on a corresponding one of the wheels and includes a three-dimensional pattern. The rubber covers prevent the hub from directly contacting the ground.

Abstract: An omnidirectional wheel includes a hub and a number of driven wheels. The hub defines a number of mounting grooves. Each mounting groove includes an axle provided therein. Each driven wheel includes a driven roller and a cover layer. Each of two ends of the driven roller defines a fixing hole. Each of the two holes receives the axle. The cover layer is sleeved on an outer side of the driven roller.

Abstract: 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.
