TECHNICAL FIELD OF THE INVENTION
(01)This invention relates to the towing portion of a pre-manufactured or home
built tow
behind trailer that attaches to the rearward towing device of an independent,
self-
propelled vehicle such as. but not limited to a small utility truck, an All-
Terrain utility
Vehicle, a 5`11 wheel dolly assembly or the rear hitch device of a towing
vehicle such as a
pickup truck.
BACKGROUND OF THE INVENTION
(02)The traditionally manufactured tow behind trailer is produced with a
rigid, fixed
style hitch that is permanently integrated with the trailers frame. This
production design
has become the main stay for trailers that are used for transporting goods
from one
location to another, in industry, business, agriculture and the private
sector. For the most
part this tow behind trailer style performs well for their intended use or
purpose. They
however have a few short comings and limitations that need to be addressed, to
give them
more flexibility in their usefulness.
(03)The first limitation associated with the traditional manufactured tow
behind trailer
hitch styles is that they can only be hooked or coupled to a matching towing
hitch style
equipped vehicle. The two primary coupling style devices are; a ball coupler
and a pintle
hook connecting device. This can restrict a trailers movement from one
location to
another because there is not a suitable towing vehicle available, due to the
trailers size,
weight, tow coupler style or the surface conditions that the trailer is to be
traveling
across.
(04)A second limitation is that the traditionally manufactured tow behind
trailer is fitted
with either a straight tongue or an A frame style of hitch tongue. These
hitches have a pre
determined weight classification rating. The result of this limitation is that
many times a
trailer is over loaded for its hitch classification or for the hitch
classification on the
towing vehicle to which the trailer has been coupled to.
(05)A third limitation for the traditionally manufactured tow behind trailer
tongue hitch
is that its single style hitch often requires a manufacturer to invest in a
greater amount of
raw materials. skilled labor and production equipment, in order to produce and
meet the
varied needs in the market place.
(06)These limitation of the traditional tow behind trailers, are some of the
reasons for the
development of the Temporary Single Arm Adjustable Goose Neck Hitch System.
SUMMARY OF THE INVENTION
(07)The temporary single arm adjustable goose neck hitch system has been
developedh to
help turn a standard rigid tow behind trailer into a temporary single arm
goose neck/5
1

wheel trailer. This conversion system will allow for greater flexibility for
on and off road
tasks that will be performed by traditional tow behind trailers. This
conversion is
accomplished by attaching a quick exchange receiver coupler near the front of
the hitch
tongue, and to the underside of the said hitch tongue frame, as an optional
accessory
piece to a pre-manufactured trailer. The said receiver coupler can also be
integrated into
the manufacturing process of a new trailer hitch tongue, as a standard
feature. This
receiver coupler accepts and locks in place the temporary single arm,
adjustable goose
neck hitch, or the fore said receiver coupler will also accept an adjustable,
temporary
straight arm tongue accessory hitch.
(08)This quick exchange temporary single arm adjustable goose neck hitch
conversion
system will use the standard coupling devices such as, but not limited to a
king pin style,
or a ball coupler style coupling device, for connecting the fore said
temporary goose neck
hitch system to an independent tow vehicle such as a small utility vehicle, a
utility ATV,
a 5' wheel dolly hitch assembly or it can be attached to the standard rear
hitch device of
a tow vehicle such as a pickup truck.
(09)There are a number of advantages for the instillation of this invention on
a
traditional tow behind trailer. The first advantage for this hitch conversion
system is that
it can be attached to a new or used trailer hitch tongue, converting a
standard straight
tongue style hitch, or a standard A frame style hitch tongue into a temporary
single arm,
adjustable goose neck style hitch system. This hitch conversion will lessen
the need to
purchase a complete custom built trailer.
(010)A second advantage of this hitch conversion system is that the
traditional trailer
towing coupling connectors such as the ball coupler connecter, or the pintle
style
coupling device can still be used with this conversion system, as an
exchangeable
accessory component pieces along with the temporary single arm, adjustable
goose neck,
and the adjustable, temporary straight tongue style of hitch. The third
advantage for the
invention is hat it can also be used as an anti-theft device. By removing the
adjustable
single arm temporary goose neck hitch or the straight tongue hitch from the
trailer frame
adjustable receiver coupler, a trailer is left without a towing device
attached to the trailer
frame hitch tongue.
(011)A fourth advantage of the temporary single arm adjustable goose neck
hitch system
is that when a 511' wheel dolly assembly is used in conjunction with this
hitch system, a
trailers function and maneuverability is greatly enhanced particularly on an
off road job
site, where a trailer can be moved with a smaller towing vehicle. In some
situations a
trailer may even be moved by hand pushing, when connecting a 51h wheel dolly
assembly
to this hitch conversion system. A heavier load may be put on to the trailer
when using
the 5`11 wheel dolly with out being in violation of the towing vehicles weight
classification
restrictions. This again gives more flexibility to a tow behind trailers
capabilities.
(012)There are also financial advantages to this hitch conversion system.
First it can
decrease the need of investing in multiple trailers because of the
interchangeable hitch
connector options that have already been mentioned. Another financial
advantage can be
2

realized in the greater choice of towing vehicles that can be used for
different purposes
and future applications. such as a trailer that is used for road travel, can
now be coupled
to an All -Terrain Utility Vehicle that has been designed for off road use.
The foresaid
advantages are just a few examples, and they should not be viewed as limiting
for other
possible advantages.

DETAILED DESCRIPTION OF THE INVENTION
(027) 1 in accordance with the object of the invention set forth in the
summary of the
invention. The Temporary Single Arm Adjustable Goose Neck hitch system is
shown in
Fig.1 as an attachment to the underside of the frame hitch tongue (9) in a
forward
position on a standard tow behind trailer (trailer not shown). This
application of the fore
said hitch system is an example for the invention being used as an optional
aftermarket
accessory piece. Fig 2 shows the fore said invention attached to a standard
tow behind
trailer frame hitch tongue (9) as an integrated standard feature of a pre
manufactured tow
behind trailer hitch tongue (trailer not shown). These two views of the
invention represent
just two hitch conversion applications for the invention, and they should not
be used as
limitations for other suitable applications for the use of this invention.
(028)The Temporary Single Arm Adjustable Goose Neck hitch system is comprised
of
the fallowing components; as shown in Fig.1 and 2. The fore said invention
conversion
application starts with a quick connect receiver coupler (1) FiG.1, 2 and 3
which has been
brought forward from CA. Pat. No 2.477.549 and having the same inventor. The
quick
connect receiver coupler (1) design starts with a length of hallow, square
steel tubing
(1a), with both of the ends left open, and function as receiver coupler ends
for the
purpose of inserting and connecting the temporary single connector arms,
insert able
connector tube (2a) Fig. 1, 2 and 4 which will be discussed in more detail in
Fig.4. The
fore said receiver coupler tube (la) FiG.3 has a plurality of pre drilled
matching holes (6)
along the right and left sides of the adjustable receiver coupler tube (la)
for inserting a
temporary fastener (7) through the holes (6) in the receiver coupler as shown
in FiG.3B,
and the pre drilled matching holes (6) in the insert able connector tubes (2a)
FiG.4 in
order to secure the temporary single connector arm (2) in place. Both ends of
the receiver
coupler tube have been fitted with a single re enforcement band (lb) that
gives added
strength and support to the receiver coupler (1) Fig.3 and 3A when used in
heavy down
or side pressure loads. Each adjustable receiver coupler is also fitted with a
steel flat
connector plate(s) (lc) FiG.1.2.3 and 3A of sufficient strength and dimension,
rigidly
attached to the top side of the receiver coupler tube (la) with a process such
as welding
for securing the said adjustable receiver coupler (1) to the trailer frames
hitch tongue (9).
This is done in such a way so that the receiver coupler (1) becomes an
optional accessory
component piece when attached to a pre manufactured trailer as shown in Fig. 1
and 3C,
or as a standard component piece on a newly manufactured trailer as shown in
Fig 2 and
3D.
(029)The fore said flat connector plate(s) (lc) FiG.3 and3A design uses two
different
methods for attaching the fore said adjustable receiver coupler (1) to a pre
manufactured
tow behind trailer frame hitch tongue (9) Fig. 1 and 2. The first method for
attaching the
4
CA 02652998 2013-06-25
2,652,998
receiver couplers flat connector plate (lc) that is attached to the top side
of the adjustable
receiver coupler tube (1a) is as a permanent attachment to the underside, and
near the
front of a trailers hitch tongue (9) by using a standard process such as
welding FiG.1.
(030) The second method used for attaching the fore said flat connector
plate(s) lc) of
the adjustable receiver coupler (1) to a tow behind trailer frame hitch tongue
(9) uses
temporary fastener(s), the fore said temporary fastener(s), include but not
limited to a U
bolt (7a) FiG.3C are of sufficient length so as to extend over the tow behind
trailer hitch
tongues frame (9), and are inserted through the pre drilled hole(s) (6) in the
flat connector
plate (lc) that is attached to the receiver coupler (1) Fig. 3, 3A and 3C
allowing for a
suitable connection of the receiver coupler (1) to the trailer hitch tongue
frame (9).
(031)There are two primary trailer hitch styles used when the adjustable
receiver coupler
(1) is integrated into the trailer frame as a part of a newly manufacturing
trailer hitch.
One is shown in Fig.2, as a straight tongue, in this style the receiver
coupler is
incorporated as a part of the hitch tongue. The 2nd hitch style is shown in
FiG.3D as an A
frame style of hitch tongue connection. In this style the trailers hitch frame
side
member(s) (9a) can be fastened directly to the sides of the adjustable
receiver coupler
tube (la) with or without the use of the connector flat plate(s) (lc). The
adjustable
receiver coupler (1) can be rotated 1/4 of a turn so that the matching pre
drilled holes (6)
will be on the top and bottom sides so that the hitch frame side members (9a)
will not be
an obstruction when inserting or removing a temporary fastener(s) (7). This
connection
process makes it possible for the fore said adjustable receiver coupler (1) to
be capable of
accepting both the temporary single connector arm (2) portion of the
adjustable goose
neck hitch system and the adjustable, temporary straight arm connector tongue
(10)
Fig.11 style hitch as a temporary interchangeable function of the invention.
(032)The temporary, single arm adjustable goose neck hitch system as shown in
Fig. 1
and 2 make up further includes a temporary single connector arm (2) that is
further
comprised of an insert able connector tube (2a) Fig. 4 that slides into the
adjustable
receiver coupler (1) that is attached to a tow behind trailer frame hitch
tongue (9) Fig.1
and 2, and is locked into place with the use of a temporary fastener (7)
FiG.3B. The
forward end of the insert able connector tube (2a) is connected to a
vertically positioned
square steel tube (2b) as shown in Fig. 1, 2 and 4. The vertical tube (2b) is
connected to
the forward end of the insert able connector tube (2a) by using a process such
as welding.
A metal gusset (2c) is welded to the right and left sides of the forward end
of the
horizontal tube (2a) and the lower end of the vertical tube (2b) to give added
support and
strength to the goose neck connector arm (2).This vertical tube (2b) is of a
sufficient
length, so as to allow the exchangeable, horizontal cross beam (4) to be an
acceptable
height, allowing for a proper clearance for the temporary single arm
adjustable goose
neck hitch system to function safely without obstructions when coupled to an
independent towing vehicle. The fore sad vertical tube (2b) has matching pre
drilled holes
(6) near the upper end, and on the right and left sides for inserting a
temporary fastener
(7) for temporarily securing the rearward adjustable double receiver connector
head (3) in
place over the upper most end of the vertical tube (2b) portion of the single
connector
arm (2) FiG4 and 6.
