20100327668 | ROBOT CRASH PROTECTOR - A robotic crash protector device is configured for heavy payload applications. The device includes a housing, a piston and an actuator movably mounted within the housing, a cam member secured within the housing in fixed relation to the housing's base, and a switch. The cam member includes a cam surface with some portions being closer to the housing's base than other portions. The actuator includes bearing members that are configured to, responsive to a rotational force imparted to the actuator, move along the cam surface and thereby collectively displace the piston. The switch detects this displacement and indicates a crash. When moving along the cam surface, the bearing members are each configured to engage the surface along a line of contact, rather than at a single point. With forces imparted to each bearing member and the cam surface distributed across a line, the components better endure heavy payload applications. | 2010-12-30 |
