The operation and use of the present invention is quite simple. The bracket means 107, 123 are fixedly attached to the vehicle 13 at the desired location (e.g., to the first and second chassis portions 17, 19 adjacent the rear bumper 20 of the vehicle 13). The distance between the first and second arm members 51, 59 is then adjusted with the slide means 67, 77, 87, 97 until the first ends 53, 61 of the first and second arm members 51, 59 can be inserted into the respective sleeve members 109, 125. The first and second arm members 51, 59 are inserted into the respective sleeve members 109, 125 the desired distance (e.g., until the first end member 39 of the frame 25 is adjacent the rear bumper 20 of the vehicle 13 as shown in FIG. 2), and the pin members 119, 135 are inserted through the respective sleeve members 109, 125 and arm members 51, 59. To easily place the load 15 onto the support member 23 or remove the load 15 from the support member 23, the pin means 173, 179 are removed from the respective boss members 169, 175 and socket means 171, 177, and the fence means 141 is pivoted to the second position. Once the load 15 has been placed on or removed from the support member 23, the fence means 141 is pivoted back to the first position and the pin means 173, 179 are inserted through the respective boss members 169, 175 and socket means 171, 177 to lock the fence in the first position.
Although the present invention has been described and illustrated with respect to a preferred embodiment and a preferred use therefor, it is not to be so limited since modifications and changes can be made therein which are within the full intended scope of the invention.
