This hitch systems forward end can be temporarily attached to, and towed by a variety of independent self propelled utility vehicles, that are equipped with a 5th wheel coupling device. The rearward end of this hitch system temporarily attaches to the most forward end of a trailer frame hitch tongue, with the use of a quick change coupler device, and is secured within the coupler by using a temporary fastener.

## Background
TECHNICAL FIELD OF THE INVENTION
This invention relates to the towing portion of a 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 pickup truck. When using this invention the foresaid trailer is converted into a single arm goose neck trailer that can be connected to, and towed by a small utility truck, an All Terrain utility Vehicle, or a 5th wheel dolly assembly.
BACKGROUND OF THE INVENTION
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.
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 towing 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.
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.
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 trailer market place.
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
The present invention is a new and improved hitch system when compared to previous inventions including the following prior art;
U.S. Pat. No. 6,109,640 issued to Allen et al, on Aug. 29, 2000 for WHEELED GOOSENECK ADAPTER FOR STANDARD HITCH TRAILER, an adapter for converting a tag-along or standard trailer to a gooseneck trailer.
U.S. Pat. No. 5,566,964 issued to Leonard on Oct. 22, 1996 for CONVERTIBLE TOWING SERVICE.
U.S. Pat. No. 5,324,061 issued to Lay on Jun. 28, 1994 for GOOSENECK HITCH APPARATUS. U.S. Pat. No. 4,832,358 issued to Bull on May 23, 1989 for TRAILER FIFTH WHEEL-GOOSENECK CONVERSION ADAPTER.
The temporary single arm adjustable goose neck hitch system has been developed for the purpose of converting a standard rigid hitch style of tow behind trailer into a temporary single arm goose neck/5th wheel trailer. This conversion system will allow for greater flexibility of a trailer when it is used for, on and off road tasks. 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 foresaid 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.
There are a number of advantages for the instillation of this invention on a traditional tow behind trailer. The quick exchange temporary single arm adjustable goose neck hitch conversion system will use the standard goose neck coupling devices such as 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 but not limited to a small utility vehicle, a utility ATV, a 5th wheel dolly hitch assembly or it can be attached to the standard rear hitch device of a tow vehicle such as a pickup truck.
A second 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.
A third advantage for this hitch conversion system is that the standard trailer towing coupling connectors including the ball coupler connecter, and 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.
A fourth 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.
A fifth advantage of the temporary single arm adjustable goose neck hitch system is that when a 5th 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 5th wheel dolly assembly to this hitch conversion system. A heavier load may be put on to the trailer when using the 5th 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.
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 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
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 under side 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 of the invention being used as an optional after market 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.
The Temporary Single Arm Adjustable Goose Neck hitch system is comprised of the following components; as shown in FIGS. 1 and 2. The fore said invention conversion application starts with a quick connect receiver coupler (1) FIGS. 1, 2 and 3 which has been brought forward from Canadian Pat. No 2,477,549 and U.S. patent application Ser. No. 12/460,864, 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) FIGS. 1, 2 and 4 which will be discussed in more detail in FIG. 4. The fore said receiver coupler tube (1a) FIG. 3 has a plurality of pre drilled matching holes (6) along the right and left sides of the adjustable receiver coupler tube (1a) 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 (1b) that gives added strength and support to the receiver coupler (1) FIGS. 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) (1c) FIGS. 1, 2, 3 and 3A of sufficient strength and dimension, rigidly attached to the top side of the receiver coupler tube (1a) 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 FIGS. 1 and 3C, or as a standard component piece on a newly manufactured trailer as shown in FIGS. 2 and 3D.
The fore said flat connector plate(s) (1c) FIGS. 3 and 3A 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) FIGS. 1 and 2. The first method for attaching the receiver couplers flat connector plate (1c) 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.
The second method used for attaching the fore said flat connector plate(s) 1c) 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 (1c) that is attached to the receiver coupler (1) FIGS. 3, 3A and 3C allowing for a suitable connection of the receiver coupler (1) to the trailer hitch tongue frame (9).
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 (1a) with or without the use of the connector flat plate(s) (1c). 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.
