ABSTRACT:
A remote actuator and interlock for a trailer hitch of the type having a main body, a ball receiving socket at one end of the main body with the other end of the main body being attachable to the end of a trailer. A pivotal member is hinged at the ball receiving socket end of the hitch. The main body and the pivotal member form hinged sections and the socket is formed jointly in the two hinged sections. A collar is reciprocatingly received about the main body and positioned to releasably receive the free marginal end of the pivotal member therein to thereby releasably latch the hinged sections together so that a ball can be captured therewithin. A remote actuator with interlock is mounted to the hitch apparatus by which the hinged sections are forced together and thereafter the collar is moved into the latched position over the hinged sections. The remote actuator includes a control lever pivotally mounted for movement respective to said main body. An actuator means is connected to be moved in response to movement of the control lever, and in response to extension and retraction of the jack device. The actuator means is positioned for engaging and retracting the pivotal member into aligned position to enable the collar to be received about the marginal free end thereof. This allows the hitch to be positioned in aligned relationship respective to a ball therefor, the collar moved into a retracted position, the pivotal member engaged by the actuator means and thereby moved into a retracted position, whereupon the collar is released and captures the marginal end of the pivotal member and retracted about a ball. Retracting the jack locks the remote actuator in the closed position.
