Trailer lock

An improved trailer locking device configured for limiting movement of a trailer, said improved trailer locking device comprising:

• an extendable support having a cross-section;
• a receiver having a complementary cross-section configured for slidable receipt of said extendable support;
• a fastening pin configured for at least partially passage through at least one side of said receiver and at least partially though said extendable support;
• said fastening mechanism configured for engagement with said fastening pin;
• an upper support spaced from a lower support said upper support and said lower support configured for mounting said receiver in a vertical position;
• one of said upper support and said lower support configured for vertical adjustment of said receiver;
• and
• a security plate mounted on said receiver and configured to at least partially obscure said fastening pin.

A method for rotating a trailer with a support extending from a proximate end to a distal end from a moveable position to a parked position whereby movement of the trailer is limited, said method comprising the steps of:

• providing an improved locking device in communication with said support, said improved locking device configured for association with the trailer, said improved locking device comprising:
• an extendable support operable for upward and downward movement;
• a receiver configured for slidable receipt of said extendable support;
• a fastening pin;
• a fastening mechanism configured for at least partial receipt of said fastening pin;
• an upper support;
• and
• a lower support;
• configuring said upper support and said lower support for securing said improved locking device near said distal end in relation to a ground surface whereby operation of said improved locking device at said distal end causes said extendable support to rotate said proximal end whereby movement of said trailer is at least partially limited;
• extending said extendable support at least partially through said receiver;
• aligning a pin receiver associated with said extendable support within said receiver for at least partial receipt of said fastening pin;
• extending said fastening pin at least partially through said receiver;
• securing said fastening pin at least partially by said fastening mechanism;
• and
• associating a shroud plate with said fastening mechanism wherein said shroud plate at least partially limits damage to said improved locking device.
