Abstract

Abstract A towing coupler assembly for removable attachment to a factory made home or the like having under-girders, for stable towing thereof. The assembly has a frame with an elevated front end and divergent lower rear ends. The front end has a coupler kingpin mounted with limited pivotal action on a longitudinal pivot axis. The frame rear ends extend under the home and attach to the under-girders. Compression units intermediate the front and rear ends are vertically operable to apply controlled compression between the home and the frame, to effect controlled load distribution and controlled elevation to the home front end. Special jack means allows attachment and detachment. Small wheels on the frame enable the novel assembly to be towed as a trailer when not attached to a home. Preferably, a coupler ball on the novel assembly engages the conventional ball coupler on the home and acts as a fulcrum for easy mounting of the assembly. Alternatively, the novel towing coupler assembly can attach to a home or the like not having the conventional ball coupler.

Claim 1
Independent Claim 142 words
An attachable-detachable towing coupler assembly for mounting to and towing of, from the front end, a parallelepiped structure having supporting under-girders and a wheeled undercarriage, comprising: a bifurcated frame having a front portion and rear portions; said rear portions being shaped to extend beneath the structure front end, being spaced from each other and including attachment zones connectable to under-girders of the structure spaced rearwardly from the front end of the structure; said frame front portion being upwardly offset relative to said frame rear portions and having cooperative coupling means thereon connectable with complementary coupling means on a towing vehicle to enable a stable elevated coupling thereto; and compression-load, structure-engagement means on said frame between said front and rear portions, to selectively engage the structure front end, thereby affording a multiple point securement for the structure while towed on its wheeled undercarriage.
Claim 2
Dependent Claim 142 words
An attachable-detachable towing coupler assembly for mounting to and towing of, from the front end, a parallelepiped structure having supporting under-girders and a wheeled undercarriage, comprising: a bifurcated frame having a front portion and rear portions; said rear portions being shaped to extend beneath the structure front end, being spaced from each other and including attachment zones connectable to under-girders of the structure spaced rearwardly from the front end of the structure; said frame front portion being upwardly offset relative to said frame rear portions and having cooperative coupling means thereon connectable with complementary coupling means on a towing vehicle to enable a stable elevated coupling thereto; and compression-load, structure-engagement means on said frame between said front and rear portions, to selectively engage the structure front end, thereby affording a multiple point securement for the structure while towed on its wheeled undercarriage.
Claim 3
Dependent Claim 48 words
The towing coupler assembly in claim 1 wherein said compression-load, structure-engagement means are vertically operable, and are located forwardly of said attachment zones to be adapted to engage the front of the structure and impart to said frame a controlled amount of vertical compression loading from the structure.

Claim 6
Dependent Claim 38 words
The towing coupler assembly in claim 4 having its center of gravity proximate said coupler ball, to enable easy connection and disconnection of said attachment zones to the structure under-girders while using said coupler ball as a fulcrum.
Claim 7
Dependent Claim 36 words
The towing coupler assembly in claim 1 including a bolster to which said cooperative coupling means is secured and which is mounted to said front end portion for limited pivotal movement on a longitudinal pivot axis.
Claim 8
Dependent Claim 15 words
The towing coupler assembly in claim 1 wherein said cooperable coupling means comprises a kingpin.
Claim 9
Dependent Claim 165 words
A towing coupler assembly for a factory made home or the like having structural support under-girders, a front cross beam, and a wheeled undercarriage, comprising: a bifurcated frame having a front end portion and including a pair of beams joined at said front end portion and rearwardly divergent to a pair of spaced rear end portions; said front end portion being upwardly offset relative to said beams and rear end portions and having a kingpin coupler for connection to a mating fifth wheel coupler on a truck tractor; vertical compression load units on both said beams, forwardly of said rear end portions, to engage the front cross beam of the home and operable to receive and impart controlled compression load to said frame from said home; and said rear end portions being attachable to the home under-girders, whereby said coupler assembly effects a multiple point connection to the home and an elevated fifth wheel connection to the towing vehicle for stable towing of the home.
Claim 10
Dependent Claim 165 words
A towing coupler assembly for a factory made home or the like having structural support under-girders, a front cross beam, and a wheeled undercarriage, comprising: a bifurcated frame having a front end portion and including a pair of beams joined at said front end portion and rearwardly divergent to a pair of spaced rear end portions; said front end portion being upwardly offset relative to said beams and rear end portions and having a kingpin coupler for connection to a mating fifth wheel coupler on a truck tractor; vertical compression load units on both said beams, forwardly of said rear end portions, to engage the front cross beam of the home and operable to receive and impart controlled compression load to said frame from said home; and said rear end portions being attachable to the home under-girders, whereby said coupler assembly effects a multiple point connection to the home and an elevated fifth wheel connection to the towing vehicle for stable towing of the home.
