US 5,181,405 A · Gooseneck trailer hitch lock

Abstract

A gooseneck trailer hitch locking device for obstructing a gooseneck coupler to prevent undesired coupling by a towing vehicle, the locking device comprising lock bodies cooperating with and obstructing the front and rear facing portions of a gooseneck coupler, a lock pin securing the lock bodies to each other, and a lock device for preventing access to the lock pin and undesired removal of the lock bodies from the coupler. The lock bodies include apertures which can be aligned with each other and with a threaded bore centrally disposed in a downward projection extending from one of the lock bodies. The lock pin is threadably received by the bore and can be extended into the aligned apertures in the lock bodies when aligned to secure the lock bodies to each other. The downward projection includes aligned openings having central axes generally perpendicular to the longitudinal axis of the threaded bore, which openings are adapted to receive the shackle of a padlock. The padlock prevents access to the lock pin and undesired removal of the lock bodies.

Dependent claims

A locking device for use with a trailer gooseneck, the trailer gooseneck 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 front and rear facing portions and being adapted for releasable attachment to a towing vehicle, said locking device comprising:

(a) a first lock body adapted to receive the rear facing portion of the coupler;
(b) a second lock body adapted to receive the front facing portion of the coupler, said second lock body being adapted to cooperate with said first lock body;
(c) securing means cooperating with said first and second lock bodies to prevent undesired removal of said first and second lock bodies from the coupler;
(d) said first lock body having a bottom defining an aperture and an interior defining channels;
(e) said second lock body having a plate defining an aperture, said plate being adapted to be slidably received in said channels in said first lock body such that said aperture in said bottom of said first lock body can be aligned with and below said aperture in said plate of said second lock body when said first and second lock bodies cooperate to prevent undesired coupling;
(f) said plate of said second lock body defining notches terminating in notch ends;
and
(g) said first lock body including stops in said channels, said stops abutting said notch ends to prevent complete separation of said first and second lock bodies.

(a) obstruction means for cooperation with the coupler to prevent undesired coupling of the coupler to the towing vehicle;
(b) securing means cooperating with said obstruction means to prevent undesired removal of said obstruction means from the coupler;
(c) said obstruction means comprising;
(i) a first lock body adapted to receive the rear facing portion of the coupler, said first lock body having a bottom defining aperture and an interior defining channels;
(ii) a second lock body adapted to receive the front facing portion of the coupler, said second lock body having a plate defining an aperture;
said plate being adapted to be slidably received in said channels of said first lock body such that said aperture in said bottom of said first lock body can be aligned with and below said aperture in said plate of said second lock body when said lock bodies cooperate to prevent undesired coupling;
(d) said securing means comprising;
(i) a projection defining a longitudinal bore extending completely therethrough, said projection attached to and extending down from said bottom of said first lock body such that said aligned apertures in said bottom and said plate of said first and second lock bodies, respectively, can be further aligned with and above said bore when said first and second lock bodies are in cooperation with the coupler, said projection further defining opposite aligned openings generally normal to said bore in said projection;
(ii) a lock pin received by said projection and extending into said bore and said aligned apertures to prevent separation of the first and second lock bodies from said coupler, said lock pin having a length adapted to extend into said bore and said aligned apertures without obstructing said opposite aligned openings in said projection;
and
(iii) lock means extending into and completely through said opposite aligned openings in said projection so as to prevent undesired access to said lock pin.
