BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure generally relates to trailer systems and methods of transporting different types of cargo. More particularly, the disclosure generally relates to convertible trailers for transporting various types of cargo.
2. Description of the Relevant Art
There are a number of different types of trailers in existence today. There exist specialized trailers for any number of different uses. Therein lies one of the problems associated with the large number of different trailers. It is not uncommon for individuals and/or businesses to require the use of more than one type of trailer.
The problem with requiring several different types of trailers is that in general trailers are very expensive to purchase and to maintain and service. The initial cost of purchasing a trailer may run from several thousand dollars at the low end to at least many tens of thousands of dollars on the high end. Typically costs being associated with how specialized the trailer is as well as how large the trailer is.
Not to be discounted are costs associated with maintaining trailers and how that is magnified if one needs to maintain multiple trailers. Common maintenance costs may include replacing tires, licensing (depending on local and federal codes), upkeep of electrical components, hydraulics, brakes, storage of the trailer, etc.
Therefore a convertible trailer system and/or method which would reduce the initial purchasing costs for a user requiring several different types of trailers, as well as reducing the maintenance costs would be highly desirable.

FIGS. 18A-D depict a diagram of a view of an embodiment of coupling system 400 for coupling trailer attachments 120 to trailer 110. The coupling system may couple during use either to the first trailer attachment or the second trailer attachment to the first side (i.e., the upper or top side) of the trailer.
In some embodiments, the coupling system may include at least two locking mechanisms 400a positioned at first end 410 of first trailer attachment 120 and at least two locking mechanisms 400b positioned adjacent second end 420 of the first trailer attachment. The second end may be positioned substantially opposite the first end.
In some embodiments, at least some of the locking mechanisms may be spring activated such that they are biased in a locked position or an unlocked position. At least some of the locking mechanisms may be spring activated such that they move, during use, from an unlocked position to a locked position when the first trailer attachment is in the loaded position. For example the locking mechanism may include a first portion mounted on a trailer attachment including an elongated member which engages an opening in a second portion of the locking mechanism mounted on a trailer. The elongated member may be operatively coupled to a spring which is biased to apply a force in a direction towards a locking position for the elongated member. In some embodiments, the elongated member may include a first engaging end with an angled cut which allows the elongated member to be repositioned as the engaging end engages the second portion and the spring then pushes the elongated member back into position through the opening once the engaging end reaches the opening in the second portion.
In some embodiments, loading system 160 may function as part of coupling system 400, such that the loading system assists in coupling trailer attachments 120 to trailer 110. For example an electric winch may be coupled to a trailer attachment during transport of the trailer attachment by the trailer. In this way the loading system may inhibit decoupling of the trailer attachment from the trailer, for example, during transport of the trailer attachment.
In some embodiments, the first surface of the first trailer attachment includes guide 500 (e.g., as depicted in FIG. 2). The guide may inhibit, during use, the first trailer attachment from moving in a lateral direction relative to the trailer. The guide may inhibit, during use, the first trailer attachment from moving in a lateral direction relative to the trailer during conveyance by the loading system and/or after the first trailer attachment has been loaded on the trailer. The guide may inhibit, during use, the first trailer attachment from moving in a lateral direction relative to the trailer such that that the guide forms at least a portion of the coupling system.
The guide may be proportioned such that it fits between two members 510 (e.g., as depicted in FIG. 17B) forming at least a portion of first side 140 of trailer 110. As the trailer attachment is loaded onto the first side of the trailer guide 500 is positioned between members 510 such that the members inhibit the guide (and subsequently the trailer attachment) from moving laterally with respect to the trailer.
In some embodiments, the guide includes a first end and a second end. The first end may be coupled to the first surface such that the second end rotates about the first end between a first position to a second position. The first position may be substantially orthogonal to the first surface (e.g., as depicted in FIG. 2). The second position may be substantially parallel to the first surface.
In some embodiments, the guide is predisposed to reside in the first position due to an applied first force. The applied first force may be provided by at least one spring or similar mechanism. The guide may move, during use, from the first position to the second position when an applied second force is provided which is greater than the applied first force. In some embodiments, the second force may be applied by the loading system as the trailer attachment is loaded on the trailer. During loading the guide may press against the end of the trailer applying enough force to move the guide from the first position to the second position such that the guide engages with the first side of the trailer.
In some embodiments, the guide is coupled adjacent to a first end of the first trailer attachment. A second end of the trailer may be oppositely positioned from the first end of the trailer. When the guide is in a first position the guide may elevate the first end relative to the second end of the first trailer attachment. When the guide is in a first position the guide may elevate the first end relative to a surface upon which the second end of the guide is positioned. When the guide is in a first position the guide may elevate the first end relative to a surface upon which the second end of the guide is positioned such that the first end of the first trailer attachment is positioned higher than the second end of the trailer. When an end is elevated, the elevation may facilitate easier loading and/or unloading utilizing gravity.
In some embodiments, the guide may include one or more stops (e.g., using a friction fit) which functions to inhibit (such that more force the guide from moving from either the first position and/or the second position. In some embodiments, the guide may include one or more locks which may be engaged in order stop the guide from moving such that the guide is locked in either the first and/or second position.
In some embodiments, elevating the first end of the trailer attachment may allow for the trailer attachment to be more easily loaded onto the trailer. In some embodiments, the trailer may include a roller mechanism (e.g., adjacent the second end of the trailer). The roller mechanism may assist in loading the trailer attachment on the trailer by reducing friction and as such requiring less power to load the trailer attachment (e.g., similar to rollers depicted in FIGS. 9A-B and 10). The trailer attachment may include one or more roller mechanisms on the underside of the trailer attachment, for example, at a first or second end of the trailer attachment (e.g., opposite of the jack or loading side there may be a roller system, wheels, or mechanism to assist trailer or automobile in loading attachment).
In some embodiments, elevating an end of the trailer attachment using the guide may allow for easier loading and unloading of cargo being transported by the trailer attachment.
In some embodiments, a method may include coupling a loading system of a trailer to a first end of a first trailer attachment and conveying the first trailer attachment from a first unloaded position to a second loaded position on the trailer. The trailer may include a first side, at least two wheels coupled to a second side, opposite the first, of the trailer, and a coupling system. The method may include coupling a first surface of the first trailer attachment to the first side of the trailer using the coupling system. The first trailer attachment may include a first function. The method may include decoupling and unloading the first surface of the first trailer attachment from the first side of the trailer. The method may include coupling the loading system of the trailer to a first end of a second trailer attachment and conveying the second trailer attachment from a first unloaded position to a second loaded position on the trailer. The method may include coupling a second surface of the second trailer attachment to the first side of the trailer using the coupling system. The second trailer attachment may include a second function. The first function and the second function may be different.
In some embodiments, a method may include inhibiting the first trailer attachment from moving in a lateral direction relative to the trailer using a guide coupled to the first surface of the first trailer attachment.
In some embodiments, a method may include applying a first force using an end of the trailer to a guide coupled to the first surface of the first trailer attachment such that a second end of the guide rotates about a first end of the guide between a first position to a second position. The first end may be coupled to the first surface of the first trailer attachment, and wherein the first position is substantially orthogonal to the first surface and the second position is substantially parallel to the first surface.
In some embodiments, the guide is coupled adjacent to a first end of the first trailer attachment. When the guide is in a first position the guide may elevate the first end relative to a second end of the first trailer attachment. The second end is oppositely positioned from the first end.
