What is claimed is: 1. A horizontally extendable self-supporting platform adapted to be removably secured to a relatively stable support, comprising: a first, relatively horizontal platform member rigidly secured to the support; and a second relatively horizontal platform member rigidly secured to and overlying the first platform member, said second platform member movable from a first position overlying the first platform member to a second position extending beyond the first platform member in substantially the same plane as the first position, the second platform member maintaining the same orientation while moving from the first to the second position; and said first and second platform members joined by pivotable pairs of parallel rigid linking members secured at each end to the respective platform members. 2. A horizontally extendable self-supporting platform as in claim 1, wherein the second platform member is securable at positions intermediate the first and second positions. 3. A horizontally extendable self-supporting platform as in claim 2, wherein the second platform member is rigid and secure at all of the positions. 4. A horizontally extendable self-supporting platform as in claim 2, wherein the platform may be locked or unlocked in each of its discrete positions using only one hand. 5. A horizontally extendable self-supporting platform as in claim 1, wherein the extendable platform is adapted to be secured to a motor vehicle. 6. A horizontally extendable self-supporting platform as in claim 5, wherein the platform is secured to the vehicle such that it pivots from a stowed position beneath the vehicle to a deployed position extending outwardly therefrom. 7. A horizontally extendable self-supporting platform as in claim 1, wherein the frame members are joined by three pair of pivotable parallel rigid linking members.
