Automatic Boat-Trailer Latch

I have invented a new and novel Automatic Boat Trailer Latch that will facilitate the loading and unloading of a boat on a trailer. When loading the boat on the trailer the boat automatically engages itself with the latch, locking itself onto the trailer and after releasing the latch, the boat can be easily launched as the trailer is slid into the water.

The invention can be best understood from the accompanying diagrams, in which

FIG. 1 is a view from the top, looking down on the latch and

FIG. 2 is a front view of the latch.

In FIG. 1, when the bow eye of the boat (10) impacts on the closed, spring-loaded, strikers (20) of the latch (30), the strikers are forced into the open position indicated by the phantom (40) in the drawing and the bow eye can pass on through until the bow eye (50), indicated in phantom, has passed the latch strikers (40), allowing the latch strikers (40) to return to their original, closed, position (20), locking the boat on the trailer. The strikers (20) are kept in the closed position by the action of the tension springs (60) pressing the strikers (20) against the stop bolts (70). The strikers are pivoted on pivot bolts (80) which connect the strikers (20) to the body of the latch (30) at a forward end of an extension which forms a recess (85) for receiving the bow eye (50). The body of the latch (30) is attached to the bow post of the trailer (90) and the tension springs (60) are attached to the strikers (20) and to the sides of the trailer bow post (90). When the boat is to be returned to the water, manually moving the strikers to the open position (40) allows the boat to float free as the trailer is backed into the water.

In FIG. 2, the following parts of the latch are visible: the strikers (20), the latch body (30), the stop bolts (70), the pivot bolts (80), and the trailer bow post (90) to which the latch is attached.
