Extension Coupling With Angle Adjusting Retainer For Use With Trailers

US Patent:
2009012, May 14, 2009
Filed:
Nov 13, 2007
Appl. No.:
11/939468
Inventors:
William M. Zilm - Glenwood Springs CO, US
International Classification:
B60D 1/02
US Classification:
280515
Abstract:
An extension coupling for interconnecting a trailer to a tow hitch with an angular opening including a mount securable to the trailer and an elongated arm having a proximal end portion rotatably attached to the mount and an opposite distal end portion. A connector pin is disposed on the distal end portion and adapted to releasably mate with the tow hitch. A retainer is mounted to the elongated arm and includes a head assembly operative to engage the angular opening of the tow hitch thereby to resist rotation of the arm relative to the tow hitch. The head assembly includes first and second faces respectively oriented at an angle with respect to one another. The faces are movable with respect to one another so as to change the angle between a larger angle and a smaller angle to correspond to the angular opening in the tow hitch.

Trailer Hitch And Extension Coupling For Use Therewith

US Patent:
6186530, Feb 13, 2001
Filed:
Apr 6, 2000
Appl. No.:
9/545856
Inventors:
William M. Zilm - Glenwood Springs CO
Assignee:
Zilm Research and Development, LLP - Glenwood Springs CO
International Classification:
B60D 146
US Classification:
280496
Abstract:
An extension coupling releasably interconnects a trailer to a tow hitch on a tractor vehicle. The apparatus includes a trailer mounting assembly adapted to releasably interconnect to the trailer. The trailer mounting assembly includes a hitch box mount adapted to be secured to a hitch box of the trailer. The trailer mounting assembly also includes an extension coupling which has a proximal end portion secured pivotally to the hitch box mount about a pivot axis. The extension coupling terminates in a distal end portion, and the distal end portion is provided with a pair of oppositely projecting trunnions that extend along a load axis that is perpendicular to the pivot axis. The apparatus also includes a tow hitch assembly adapted to be secured to the bed of a tractor vehicle. The tow hitch assembly includes a pair of spaced apart receivers sized and oriented to engage the trunnions of the extension coupling to define an engaged state.

Hitch System For Use With A Ball Hitch And Methods Therefore

US Patent:
7588262, Sep 15, 2009
Filed:
Apr 4, 2008
Appl. No.:
12/098327
Inventors:
William M. Zilm - Glenwood Springs CO, US
International Classification:
B60T 7/12
US Classification:
280432, 2804171, 2804412, 2804551
Abstract:
A hitch system for interconnecting a trailer to a tow vehicle, wherein the tow vehicle includes a hitch ball centered about a medial axis. The hitch system includes an elongate extension coupling having a proximal end portion rotatably mountable to the trailer and extending toward a distal end portion that is movably mountable to the hitch ball, and an anti-yaw mounting assembly for interfacing the extension coupling to the hitch ball such that the distal end portion is restricted from rotating about the medial axis.

Methods And Apparatus For Ball And Socket Coupling

US Patent:
8205905, Jun 26, 2012
Filed:
May 6, 2011
Appl. No.:
13/102729
Inventors:
William M. Zilm - Glenwood Springs CO, US
International Classification:
B62D 1/06
US Classification:
280512, 280511
Abstract:
Methods and apparatus may permit a ball and socket coupling arrangement. A rotary interference member () and a rotary socket member () may be displaced from a hitch ball interference position () and a hitch ball socket position (), respectively, to a hitch ball clearance position () by a hitch ball () moving through a trailer coupling path (). A hitch ball socket () may be formed in part by a socket engagement surface () of a rotary socket member (). A hitch ball guidance cone () may guide the hitch ball () through the trailer coupling path (). A control rod () may be used to displace the rotary interference member () and the rotary socket member () from a hitch ball interference position () and a hitch ball socket position (), respectively, to a hitch ball clearance position ().

Extension Coupling For Use With Trailers

US Patent:
5890728, Apr 6, 1999
Filed:
Apr 17, 1997
Appl. No.:
8/841893
Inventors:
William M. Zilm - Glenwood Springs CO
International Classification:
B62D 5306
US Classification:
280433
Abstract:
An extension coupling releasably interconnects a trailer to a tow hitch on a tractor vehicle. The coupling includes a mount that is secured to the trailer. An elongated arm has a proximal end portion secured to the mount. A connector pin is disposed on a distal end portion of the arm in order to mate with the tow hitch, A retainer assembly is secured to the arm and engages the tow hitch when the trailer is interconnected to the tractor vehicle so as to resist rotation of the arm relative to the tow hitch. The mount includes a flat base plate and a pair of upwardly projecting side plates disposed on the base plate. This mount then engages the hitch connecting station on the trailer. The invention includes a trailer provided with the coupling where the trailer has a housing, a wheel set and the hitch connecting station.
