A dolly for moving objects having a rectangular platform with casters mounted underneath, having four posts which may be raised from the base and locked into an upright position. The posts further have crossbars pivotally mounted thereon, which are releasably connectable to the crossbars of adjacent posts, to form a supportive railing around the tops of the posts. The posts may further be connected by means of telescopic arms, which are pivotally connected to one crossbar, and extendible to another crossbar, wherein they may be releasably connected by means of a knob at the end of the telescopic arm being pressed into an inverted teardrop-shaped receptacle.

1. An adjustable transport dolly for storing objects between at least two locations, said adjustable dolly comprising: a. a rectangular platform having four sides, the platform having a narrow dimension and a wide dimension, and having at least one caster mounted to its underside;b. a post storage mounted on each side having a wide dimension;c. two first posts and two second posts each pivotally mounted to said post storage at a corner of said platform, each post being moveable between open and closed positions, each post having two crossbars pivotally mounted thereto, the crossbars for connecting with the adjacent post across the narrow dimension and the adjacent post across the wide dimension;d. said first and second posts having a locking mechanism that control pivoting of said posts, the locking mechanism comprising: i. a slider hinge mounted to the underside of said platform;ii. a locking slider pivotally mounted to said hinge, wherein the locking slider is in contact with said post storage;iii. a locking pin connected to said locking slider wherein the locking pin is locked and released by movement of the locking slider, wherein the locking slider exerts force against said post storage when moved into a locked position by caroming against the post storage. 2. The dolly of claim 1, wherein in a closed position the second post lies in a horizontal orientation below the first post within the post storage. 3. The dolly of claim 1, each post further comprising telescopic arms for connection to adjacent posts, the telescopic arms comprising: a. an external segment pivotally connected to the first post;b. an internal segment slidably extendable from said external segment, the internal segment having an outer tip at its extremity and a knob mounted to said outer tip;c. the second post having an inverted teardrop-shaped receptacle for releasably restraining said knob. 4. The dolly of claim 3 wherein each post has two telescopic arms for connection to adjacent posts. 5. The dolly of claim 1, wherein the crossbars are formed of crossbar sections having a length of approximately half of the distance between adjacent posts. 6. The dolly of claim 5, wherein a first crossbar is releasably connected with a second crossbar of an adjacent post by a connecting means comprising: a. a brace slidably mounted within a crossbar section;b. a switch operably connected to said brace wherein said crossbars sections each have an opening, and said switch may be moved from said opening of the first crossbar section to said opening of the second crossbar section, so as to slide the brace between said crossbar sections. 7. The dolly of claim 5, wherein a first crossbar section is releasably connected with a second crossbar section of an adjacent post by a connecting means comprising: a. a brace slidably mounted within a first crossbar section, the brace having grooves at a tip protruding from an end of the crossbar section;b. a spring operatively connected between said brace and said first crossbar section, to bias the tip towards the end of said crossbar section;c. the second crossbar section having a locking rod mounted therein for interfacing with said grooves wherein said grooves are releasable by sliding said brace away from the end of the crossbar section. 8. An adjustable transport dolly for storing objects between at least two locations, said adjustable dolly comprising: a. a rectangular platform having first and second pairs of sides of equal dimension, and having at least one caster mounted to its underside;b. a post storage mounted on each of one pair of sides;c. two first posts and two second posts each pivotally mounted to said post storage at a corner of said platform, each post being moveable between open and closed positions, each post having two crossbars pivotally mounted thereto, the crossbars for connecting with the adjacent post across one of said first pair of sides and the adjacent post across one of said second pair of sides;d. said first and second posts having a locking mechanism that control pivoting of said posts, the locking mechanism comprising: i. a slider hinge mounted to the underside of said platform;ii. a locking slider pivotally mounted to said hinge, wherein the locking slider is in contact with said post storage;iii. a locking pin connected to said locking slider wherein the locking pin is locked and released by movement of the locking slider, wherein the locking slider exerts force against said post storage when moved into a locked position by camming against the post storage.
