## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a trailer adapted to be hitched to the rearward end of a vehicle and more particularly to a trailer including a detachable cargo carrier which may be selectively removably secured to the rear of the trailer to increase the carrying capacity of the trailer or which may be selectively removably secured to the box receiver at the rear end of the vehicle when the vehicle is not being used to tow the trailer. Even more particularly, this invention relates to a trailer of the type described which may be secured to the rearward end of a vehicle in a substantially vertically disposed position when the trailer is not being used to transport cargo. Even more particularly, this invention relates to a trailer of the type described wherein the cargo carrier may be selectively removably secured to the trailer when the trailer is in its substantially vertically disposed transport position. The trailer may also be stored in a garage or the like in a vertically disposed position with the cargo carrier being secured to the underside of the trailer.
2. Description of the Related Art
Many types of trailers have been previously provided with the trailer being towed by a vehicle. Usually, the vehicle has a box receiver at the rearward end thereof into which is received a tow bar or hitch bar with the hitch bar having either a clevis or hitch ball secured to the rearward end so that the trailer may be hitched thereto. There are many times when the conventional trailer being towed by a vehicle is too small for a particular load. Further, there are many times when the trailer is towed by the vehicle without the trailer having any cargo positioned thereon. Many residential areas prohibit the storage of trailers outside of a garage or the like. When the trailer is stored in a garage or the like, it takes up considerable space.
SUMMARY OF THE INVENTION
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
A trailer is disclosed for use with a vehicle having a forward end, a rearward end and a longitudinally extending first box receiver at the rearward end thereof which has an open rearward end.

A vertically disposed pocket or tubular member 128 is welded to tube 118 adjacent the rearward end thereof. A pair of transversely extending and horizontally spaced-apart pivot tubes 130 and 132 are welded to the upper surface of tube 118 (FIG. 4).
As seen in FIG. 4, a vertically disposed channel member 134 has a tube or bar 136 extending transversely therefrom which is welded thereto. Tube 136 is comprised of tube portions 138 and 140. Tube portion 140 is slightly smaller than tube portion 138 to define a shoulder 142 therebetween. Tube portion 140 has an opening 144 formed therein with tube portion having an opening 146. Tube portion 138 also has a pair of smaller openings 148 and 150 formed therein. Each of the sides of channel member 134 has a plurality of vertically spaced-apart openings 152 formed therein to permit the channel member 154 of trailer coupler 156 to be selectively vertically adjustably secured to tube 136. As seen, the sides of channel member 154 have vertically spaced openings 158 formed therein. Pins 160 and 162 are utilized to adjustably secure coupler 156 to channel member 134.
A stand 164 is selectively pivotally secured to tube portion 138 by pins 166 and 168 to enable the stand 164 to be vertically disposed to support the forward end of the trailer 10 when coupler 156 is disconnected from the vehicle hitch. Stand 164 may also be selectively pivoted to a substantially horizontal position and pinned in that position for transport.
Cargo carrier 12 includes a frame means 170 having a deck or bed 172 positioned thereon. The cargo carrier includes a forward end 174, a rearward end 176, a right side 178, and a left side 180. A tubular hitch bar 182 is secured to the frame means 170 and extends forwardly therefrom. As seen, hitch bar 182 has an opening 184 formed therein adjacent the forward end thereof. The right side of cargo carrier 12 has vertically disposed pockets 186, 188, 190 and 192 provided thereon. The left side of cargo carrier 12 has vertically disposed pockets 194, 196, 198 and 200 provided thereon. The lower ends of the vertically disposed posts 202 and 204 of member 206 are selectively removably received in pockets 188 and 190 respectively. The lower ends of the vertically disposed posts 208 and 210 of member 212 are selectively removably received in pockets 196 and 198 respectively. The lower ends of the vertically disposed posts 214 and 216 of member 218 are selectively removably received in pockets 192 and 200 respectively. Pockets 186, 188, 190, 102, 194, 196, 198 and 200 include conventional detents. As will be described in more detail later, hitch bar 182 may be inserted into the box receiver 16 of the vehicle 14 or inserted into the two spaced-apart pockets 220 and 222 which are secured to the underside of the trailer 10.
FIG. 1 illustrates the trailer in its towing position with the coupler 156 at the front of the trailer being adapted to be received by a ball hitch at the rear of the vehicle. FIG. 1 also illustrates that the member 74 may be selectively removed from the pockets 72 and 82 so it will be able to serve as a stand as will be later described. The same is also true of member 58. When it is desired to increase the carrying capacity of the trailer 10, the railing or rack 90 at the rear of the trailer is removed from the pockets 84 and 68 and the cargo carrier 12 is secured to the trailer by inserting the hitch bar 182 into the box receiver 98 at the rear of the trailer. When the cargo carrier is installed or secured to the trailer 10 as illustrated in FIG. 2, the carrying capacity of the trailer is dramatically increased.
The cargo carrier 12 may also be used independently of the trailer 10 with the hitch bar 182 being received by the box receiver 16 of the vehicle. In its normal use, as seen in FIG. 4, the rearward end 122 of the hitch bar 118 will be inserted into the forward end of the box receiver 106 with the pin 116 securing the same. As seen in FIG. 4, the hitch bar portion 140 is received by the forward end of the tube 118. The coupler 156 may be vertically adjustably secured to the channel member 134 by the pins 160 and 162. The channel member or stand 164 may be pivotally moved to its horizontally disposed position and pinned in that position by the pins 166 and 168. If the stand 164 is going to be used to support the forward end of the trailer, the stand 164 will be pivotally moved to its vertically disposed position and pinned into that position by the pins 166 and 168.
When it is desired to transport the trailer without the trailer being used for cargo, the tube 118 will be removed from box receiver 106, and the tube portion 140 will be removed from the forward end of the tube 118. The trailer 10 is then moved so that its rearward end is positioned adjacent the rear of the vehicle. The tube portion 140 of the tube 136 is then inserted into the box receiver 98 as illustrated in FIG. 5. The cover or door 100 is then raised to gain access to the opening 104 so that the pin 102 may be used to secure the tube 136 in the box receiver 98. The rearward end of tube 118 will then be inserted into the box receiver 16 at the rear of the vehicle and pinned thereto. The trailer 10 is then maneuvered so that the lowermost pair of openings 152 in the channel member 134 are positioned at opposite sides of the pivot tube 130 with the pin 162 then being inserted through the sides of the channel member 134 and the pivot tube 130. The bar 50 is then removed from the front rack or railing of the trailer with the lower end thereof being inserted into the pocket 128. The winch cable 112 is then unreeled from the winch 108 and secured to the bracket or clip 52 on post 50. The winch 108 is then operated to move the trailer from the position of FIG. 6 to the position of FIG. 7. When the trailer is in the position of FIG. 7, the channel member 134 embraces the tube 118 and the pin 160 is then inserted through registering openings of the channel member 134 and the pivot tube 132. It is recommended that chains, such as illustrated in the drawings, be used to secure the trailer in the position illustrated in FIG. 8. When the trailer is in the position of FIG. 7, the cargo carrier 12 is secured to the pockets 220 and 222 by inserting the hitch bar 182 downwardly through the pockets 220 and 222 and a pin then being inserted through the hitch bar 182 to maintain the hitch bar in that position.
When it is desired to store the trailer 10 in a garage or the like, the trailer is positioned in the same position as illustrated in FIG. 7 except that the trailer is not secured to a vehicle. The members 58 and 74 are inserted through the pockets 68 and 84 respectively which maintains the trailer in its vertically disposed position adjacent a wall or the like so as to occupy very little space as seen in FIG. 9.
Thus it can be seen that the invention accomplishes all of its stated objectives.
