Automatic hitch system
First Claim
1. An automatic system for hitching to a pulling vehicle a trailing vehicle, comprising a first hitch section to be mounted on said pulling vehicle and a second hitch to be mounted on said trailing vehicle, wherein said first hitch section comprises:
- a bottom channel (3) to receive the extending tongue portion of the pulling vehicle;
a hitch pin with pull handle (C) passing through an aperture (37) drilled on the top surface of an horizontal upper plate (8) welded thereon said bottom channel (3), an aperture drilled on the forwardly tongue portion of the pulling vehicle, and of which the hitch pin is vertically aligned with an aperture (4) drilled through the bottom of said channel (3);
a structural body member (13) mounted on the top surface of the upper plate (8) and welded thereon;
a pin (16) mounted and welded on the top surface of said upper plate (8) for blocking said body member (13) thereon; and
a part member (10) mounted and welded thereon the front portion of said upper plate (8) for blocking a locking member (22) when a tension spring (28) applies a pressure on a rectangular block (27) in an angular notch formed in the edge of the locking member (22) to be locked with a vertical hitch pin (58) being guided by a V-shaped cut toward a rounded recess being formed with the front portion of said upper plate (8), and when uncoupling the driver pulls a cable (32) that is securely installed into the pulling vehicle to withdraw the rectangular block (27) from the angular notch of which enabling rotation of the locking member (22) about a pivot (11) to be unlocked from the vertical hitch pin (58), and which moves forward with the pulling vehicle to release a lever (1) from a foot member (39) which is capable of returning downwards by the tension force produced through each spring (61)(66).

Abstract
An automatic hitch system which is capable to automatically couple or uncouple a pulling vehicle with a trailing vehicle without the need of the driver to get out of the pulling vehicle. The automatic hitch system comprises a first hitch section to be mounted on a pulling vehicle to be hitched to a second hitch section mounted on a trailing vehicle, and which allow the automatic positioning, coupling and uncoupling of the pulling vehicle with respect to the trailing vehicle. The first hitch section of the invention comprises a bottom channel to receive the extending tongue portion of the pulling vehicle. The bottom channel includes at its lower end a lever with contact flanges to fold up the foot member of the second hitch section underneath the extending drawbar of the trailing vehicle during the coupling operation.
