Patent attributes
A security device for a coupler for a trailer includes a bracket, a clamp lever cover, and a cover lock. The bracket is connected to the coupler, which includes a socket, a ball clamp, and a clamp lever. The clamp lever cover is engaged with the bracket and, in a secured arrangement, prevents movement of the clamp lever, thereby holding the ball clamp in a clamped arrangement, in turn retaining a hitch ball within the socket or preventing insertion of a hitch ball into the socket; in an unsecured arrangement the cover permits movement of the clamp lever from the engaged structural arrangement to the disengaged structural arrangement, thereby releasing the hitch ball or permitting insertion of a hitch ball. When unlocked the cover lock permits movement of the clamp lever cover to the unsecured arrangement; when locked retains the clamp lever cover in the secured arrangement.
