DETAILED DESCRIPTION
[0060] The following description provides detail of various embodiments of the invention, one or more examples of which are set forth below. Each of these embodiments are provided by way of explanation of the invention, and not intended to be a limitation of the invention. Further, those skilled in the art will appreciate that various modifications and variations may be made in the present invention without departing from the scope or spirit of the invention. By way of example, those skilled in the art will recognize that features illustrated or described as part of one embodiment, may be used in another embodiment to yield a still further embodiment. Thus, it is intended that the present invention also cover such modifications and variations that come within the scope of the appended claims and their equivalents.
[0061] Generally, the multi-purpose trailer of the present invention includes a frame supported by transport members such as wheels or the like. In an embodiment of the invention the multi-purpose trailer is 5 feet wide, 11 feet long, and has a capacity of 1,000 pounds when fully loaded. The frame has a first end, a second end, a first side and a second side. The transport members (wheels) are rotatably mounted to each side and of the frame. The first end of the frame has a connection member such as a hitch for connecting the trailer to a vehicle. The vehicle may be of any type such as an automobile, truck, motorcycle, tractor, or the like. The sides of the frame have a first section that extends from the connecting member to a hinge point, and from the hinge point to the rear or second end. Mounted to and above the frame, between the connecting member and the hinge point is a first container or compartment. The compartment has a top wall, side walls, end walls, and a bottom wall that form an inner chamber. The inner chamber is separated into sub-chambers by internal separating walls. The sub-chambers include one for dry and/or warm food storage, a second for cold food storage, and a third for a cooking apparatus 48 such as a grill, a smoker, or the like. The cold food storage may include insulation along the side walls and the internal separating walls. Also, each sub-chamber has an opening in the top wall and may have a door with a lock.
[0062] Mounted to and above the frame, between the hinge point and the second end, and to each side of the frame are second and third compartments. The second and third compartments have a first or front edge, a second or rear end wall, an outer side wall that extends between the front edge and second end wall, inner edge, a bottom wall and a slidable or rolling cover that slides or rolls along a top edge of the second end wall. The compartments mirror one another and, in a closed or transport position, engage one another along the inner edge.
[0063] Disposed within the second and third compartments are seating devices such as a bench, chairs, or the like. Preferably, seating capacity for eight is provided. When in the closed transport position, the second and third compartments permit storage of additional items such as tents, chairs, stools, fishing poles and the like.
[0064] In one embodiment a table or shelf extends from a side wall of the first compartment toward the second end of the frame. Preferably the table is positioned adjacent the frame at the bottom of the first compartment and is triangular in shape. The front edge is preferably angled to align with and engage the triangular shape of the table. Attached to the outer side wall of each of the second and third compartments are jacks. The jacks, while raised in a closed transport position, are used to support the trailer when not attached to a vehicle. Pivotally attached to the rear end wall of both the second and third compartments are a second set of jacks. These jacks, as will be explained, include a transport member such as a wheel. Mounted to an outer surface of the rear end walls are brackets. The brackets are used to lock the second and third compartments together in the closed transport position. Also, in one embodiment, an awning either can be raised from or attached to the second and third compartments to provide shade.
[0065] In operation, the trailer is transported, in the closed transport position, to a desired location. Once at the desired location, the adjustable height jack stands are lowered to contact the ground. A front swing back jack is used to disconnect the trailer from the vehicle. The front jack is then lowered so that the trailer wheel pivot up and off the ground. The back trailer sections are moved to an open, non-transport position. Rear swing back jacks are then lowered to stabilize the back sections and provide stability to the benches.
[0066] Alternatively, to move the trailer to the open non-transport position, the rear jacks are provided with wheels instead of pads and are pivoted from a generally horizontal position to a generally vertical position. The jacks are extended until the jack wheels engage a ground surface. Any apparatus that has been used to lock the second and third compartments together using the brackets are removed. The second and third sections, which are hingedly connected to the first compartment at the first edge, are separated by manually moving the compartments apart at the rear end wall as the jack wheels move across the ground surface. When separated, looking from above, the compartments or sections form a Y-shape. The forward adjustable height jack stands are then lowered to engage the ground surface, and the trailer may, if desired, be removed from the vehicle. Each section may have a separate cover or a single cover the width of the trailer may be used to cover the rear compartments or sections when the trailer is in a towable orientation. The covers may be slid outwardly away from the second and third compartments to provide counter/bar/table top space. A propane tank, preferably connected to the first section of the frame, is connected to the cooking apparatus.

[0157] With reference to the Figures, various embodiments and components of the multi-purpose trailer 10 according to aspects of the invention will be described in greater detail. Embodiments of the trailer 10 in accordance with the present invention are shown in the closed or towing position in
[0158] Bracing 28 is fixed to the frame 20 to provide further support to compartments positioned on the frame. Spindle attachment reinforcement 30 is fixed to an underside of each side section 100 and 150. First and second vertical supports 32 extend upward from the frame and provide rigidity for mounting the offset hinges. Additional bracing 36 provides additional structural integrity for components fixed to the frame. Fenders 46 mount to the sidewalls 102 and 152 of respective side sections 100 and 150. The fenders 46 cover a top portion of wheels 40 to reduce an amount of debris and road spray flung onto the sides of the trailer.
[0159] Axle-less trailer suspension systems 44 are mounted to spindle attachment reinforcement plates 30. Also attached to the free end of tongue 26 is a swing back jack 52. The jack pivots between two locking positions—the towing position and the trailer support or stowed position. The jack includes a handle to extend or retract an inner support from the jack. Rear swing jacks are mounted to each rear end of the second and third sections 100 and 150.
[0160] Front section 60 includes a front triangular ledge 60 and a front sidewall extending upward from the ledge. Bracket 64 is attached to the sidewall and is suitable for securing propane tank 66 to the sidewall. A propane hose 68 extends from the tank into a first compartment 70. Storage door 72 provides access to the first compartment 70 (see also
[0161] Second section 100 has a longitudinal axis that aligns parallel with the longitudinal axis of the tongue 26. The second section includes a sidewall 102 and flooring 104. Underneath the flooring 104 is a support framework that includes bracing 106 and beams 108 that extend lengthwise. Bracing 106 provides additional support and rigidity for the spindle reinforcement attachment 30. Vertical support 114 extends from the framework and provides structural integrity to the sidewall 102 and hinges 110 and 112. The hinges are spaced apart and pivotally couple the second section 100 to a first end of the front section 60. The hinges are offset such that when the second section 100 pivots open the sidewall 102 doesn't pinch against or contact the front section 60. One end of each hinge 110 and 112 is fixed to vertical support 114 and the other end is fixed to the vertical support 32 fixed to the frame 20 and first section 60 (see also
[0162] Third section 150 has a longitudinal axis that aligns parallel with the longitudinal axis of the tongue 26. The third section includes a sidewall 152 and flooring 154. Underneath the flooring 154 is a support framework that includes bracing 156 and beams 158 that extend lengthwise. Bracing 156 provides additional support and rigidity for the spindle reinforcement attachment 30. Vertical support 164 extends from the framework and provides structural integrity to the sidewall 152 and hinges 160 and 162. The hinges are spaced apart and pivotally couple the third section 150 to a first end of the front section 60. The hinges are offset such that when the second section 150 pivots open the sidewall 152 doesn't pinch against or contact the front section 60. One end of each hinge 160 and 162 is fixed to vertical support 164 and the other end is fixed to the vertical support 34 fixed to the frame 20 and first section 60 (see also
[0163] A table 200 is mounted to each outer sidewall 102 and 152 of the second and third sections 100 and 150. Hinge 202 mounts the table to the sidewall and allows the table to pivot between and upright position and a stowed position. When in the stowed position a resilient securing strap 206 attached to the sidewall is stretched and engages a hook 204 attached to the table. In this manner the table 200 is secured in the stowed position. To release the strap, the user simply stretches the strap further and disengages the strap 206 from the hook 204. A folding support 208 is fixed to the sidewall with a hinge 210. When the table is pivoted upward to the upright position the support 208 is pivoted outward to support the underside of the table 200 (see also
[0164] Cover 200 has one end fixed to front section 60 and opposing lengthwise edges engage the top sides of the second and third sections (see also
[0165] Adjustable height jack stands 370 are mounted to the rear outer ends of the first section 60. The jack stands include an outer tube 378 and inner tube 376. The outer tube includes a single aperture suitable for receiving pin 372. The inner tube includes multiple apertures extending through the tube and spaced along the length of the inner tube. A bottom pad is fixed to a free end of the inner tube. The inner tube 376 is sized to slide within outer tube 378. As the inner tube slides within the outer tube the user may choose and align an aperture of the inner tube with the aperture of the outer tube. When the desired alignment is achieved pin 372 is pressed through both apertures to thereby secure the inner tub within the outer tube. A securing pin 374 may be used to hold pin 372 in place (see also
[0166] In use, the user may couple the trailer 10 to a vehicle utilizing the hitch 50, safety chains 48 and wiring 352. When the user desires to expand the trailer 10, the trailer is detached from the vehicle and the front jack 52 is pivoted to contact the ground. The jack is extended to lower the rear end of the trailer. The jack stands 370 are then extended so that the pads 380 are in contact or near contact with the ground. The pins 372 are then positioned to fix the height the jack stands 370 are extended. Once the jack stands 370 are fixed the user lowers the front jack 52 to thereby elevate the rear of the trailer. As the rear of the trailer elevates wheels 40 will raise above the ground. Once wheels 40 are no longer contacting the ground the user may disengage latches 130, 132, 180 and 182 and swing the second and third sections 100 and 150 laterally outward. Once the sections have been opened to the desired orientation the rear jacks 56 may be pivoted down and the front jack raised so that the trailer 10 and table 200 are level and the rear jacks contact the ground.
[0167] Those skilled in the art will appreciate that modifications may be made to the attachment points, supports, links, braces, couplings and other structure of the trailer without departing from the scope of the invention. By way of example, those skilled in the art will appreciate that additional supports or locking members may be added to the bottom of the frame when the sections are in the stowed or towing position. Further, those skilled in the art will appreciate that additional wheels, dimensional changes, lighting, television, generator, kayak rack, bike rack and other accessories may be added to the trailer 10 without departing from the scope of the invention. Those skilled in the art will further recognize that the trailer 10 may be modified to replace benches with fold out beds to convert the trailer to a camping trailer.
[0168] These and various other aspects and features of the invention are described with the intent to be illustrative, and not restrictive. This invention has been described herein with detail in order to comply with the patent statutes and to provide those skilled in the art with information needed to apply the novel principles and to construct and use such specialized components as are required. It is to be understood, however, that the invention can be carried out by specifically different constructions, and that various modifications, both as to the construction and operating procedures, can be accomplished without departing from the scope of the invention. Further, in the appended claims, the transitional terms comprising and including are used in the open ended sense in that elements in addition to those enumerated may also be present. Other examples will be apparent to those of skill in the art upon reviewing this document.
