Abstract:
I claim a locking device for use with a gooseneck trailer, the gooseneck trailer having a post with upper and lower ends, the upper end being attached to a trailer and the lower end being attached to a coupler, the coupler having a receiver for a towing ball and being adapted for releasable attachment to a towing vehicle, said locking devise comprising:(A) a lock adapted to be inserted into the coupler receiver, said lock having a lock body portion and a rounded top for fitting into a fixed, upper, portion of the coupler receiver wherein when a moveable, lower, portion of the coupler receiver is moved to a locked position, the bottom portion of said locking device moves to an offset position with the moveable, lower, portion of the coupler receiver,(B) when in the offset position, said rounded top is adapted to secure the locking device in the trailer receiver coupler,(C) a key operated barrel lock in said lock body portion and a locking tang, which is attached to an end of the key operated barrel lock, wherein said locking tang is moved behind a slider which is attached to the rounded top thereby locking said bottom portion in said offset position and preventing movement of the rounded top relative to the lock body portion.(D) said locking device will remain in the coupler receiver until the locking tang is moved from behind the slider and the receiver coupler is moved to the open position.(E) with said locking device secured in the trailer receiver coupler, attachment to a towing vehicle is prevented.
