text: it will be readily understood that the components of the embodiments as generally described and illustrated in the figures herein could be arranged and designed in a wide variety of different configurations . thus , the following more detailed description of various embodiments of the present invention , as represented in the figures , is not intended to limit the scope of the invention , as claimed , but is merely representative of the embodiments of the invention . the folding / re - configurable multi purpose portable trailer is intended to be a lightweight , easily reconfigurable , multi purpose , compact device . the portable trailer has easily removable and configurable deck panels . the wheel - hub - spindle - spring assemblies are unique in that they are collapsible to a compact configuration for space savings . the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics . the described embodiments are to be considered in all respects only as illustrative and not restrictive . the scope of the invention is , therefore , indicated by the foregoing illustrative description . all changes that come within the meaning and range of equivalency of the description are to be embraced within their scope . fig1 shows a complete trailer system which consists of a center deck assembly 1 . 1 , multiple deck panels 1 . 2 and a hitch assembly 1 . 3 . the center deck assembly 1 . 1 also contains the wheel and axle assembly with leaf spring mechanism . these main items make up a usable utility trailer system and will be readily understood by any individual with common knowledge in this industry . the deck panels are shown evenly distributed or attached to the center assembly but this is not a required configuration . it may be preferable to configure the trailer with three panels on the hitch side of the axle and one panel on the rear side of the axle for stability purposes . it may also be advantageous in some instances to use more or less panels than shown in fig1 . fig2 shows the same components as identified in fig1 in a folded / storable configuration ( top , front , right , and isometric views ). the hitch assembly , item 1 . 3 , is shown detached and stored in between panels . the wheel axle assembly is shown folded . during the folding process it may be advantageous to fold only the panels and leave the wheels extended as the user maneuvers the assembly into position . the assembly thus becomes a natural dolly during the storage process . when the user reaches the position of storage the wheels can then be folded up for further compact ability . fig3 shows multiple views of the center deck panel with attached wheel and axle assembly . item 3 . 1 is the removable axle . the axle , item 3 . 1 , is pinned in multiple locations , 3 . 7 a , 3 . 7 b , 3 . 7 c , and 3 . 7 d , to prevent rotation of the wheel assemblies , items 3 . 3 a and 3 . 3 b , and to carry the associated loading . the axle , 3 . 1 , can be easily removed to allow the wheel assemblies , item 3 . 3 a and 3 . 3 b , to pivot around the axis of points 3 . 8 a and 3 . 8 b . item 3 . 2 shows a bracket assembly which connects the leaf spring to the main center deck panel , 3 . 6 , and allows the wheels to pivot around the axis of points 3 . 8 a and 3 . 8 b . another bracket , item 3 . 4 , is similar to item 3 . 2 in that it rotates around points 3 . 8 a and 3 . 8 b , but it is not directly connected to the leaf spring , item 3 . 10 . item 3 . 4 is connected to the leaf spring , item 3 . 10 , thru a standard trailer shackle , item 3 . 9 . fig4 shows multiple views of the center deck panel , item 3 . 6 , with attached wheel and axle assemblies 3 . 3 a and 3 . 3 b in a folded configuration . the wheel assemblies , items 3 . 3 a and 3 . 3 b , have rotated around points 3 . 8 a and 3 . 8 b . after rotation into the storage location , approximately 90 degrees , the axle , item 3 . 1 is then reattached to the main deck panel , item 3 . 6 , in such a manner as to lock the wheel assemblies , items 3 . 3 a and 3 . 3 b , into a closed , compact position . item 4 . 1 is a tab used to lock the deck panels in position when configured as shown in fig2 using a locking pin item 11 . 1 . the center deck assembly as described in fig3 and fig4 is designed such that compact storage can be achieved yet the loads required during operation on the axle , item 3 . 1 , the wheel assemblies , items 3 . 3 a and 3 . 3 b , and the deck , item 3 . 6 , can be withstood . the hardware required to transfer the load from the wheel assemblies , items 3 . 2 and 3 . 4 , are appropriately sized to withstand the loading . fig5 shows multiple views of a standard deck panel item 1 . 2 . the deck panel has locking mechanism at each corner to allow quick attachment to the center deck panel or to another deck panel . the locking mechanism will be further described in fig1 . the mechanism to prevent axial movement of panels will be described in fig1 . the side panels and the center deck panel all contain a pivoting metal plate , item 11 . 2 . the plates , item 11 . 2 on each corner are not identical but are mirrored ( left and right ) such that panels can be joined together . when a panel is placed into position to be connected with an adjoining panel it may need to be rotated 180 degrees so that the corners of each adjoining panels are aligned properly for connection . item 5 . 1 is a gusset used to attach the hitch , item 1 . 3 , when the unit is in its extended configuration . fig6 shows a deck panel , item 1 . 2 , configured as a stove . the gas burners , item 6 . 1 are a permanent assembly inside of the panel . this configuration shows an expanded metal top . removable legs , items 6 . 2 are removed from the storage location inside the panel and attached as legs . all necessary components for a working stove can be included inside the deck panel . the deck panel can also be used as a utility trailer deck panel when not configured as a stove . fig7 shows two deck panels , items 1 . 2 , configured as a cargo platform . item 7 . 1 is a standard rectangular steel tube that fits in a standard receiver hitch and is pinned for operation . this configuration shows only two panels but more panels may be used if desired . the standard locking mechanisms used to connect panels when configured as a utility trailer are used to connect the panels for use as a cargo platform . the inner gussets , item 5 . 1 , contained in each standard deck panel allow for a common attachment point to connect the receiver hitch , item 7 . 1 , to the deck panel , item 1 . 2 . fig8 shows two deck panels , items 1 . 2 , configured as a stool or bench . hardware , item 8 . 1 and 8 . 2 , can be used to configure the panels . the standard locking mechanisms used to connect panels when configured as a utility trailer are used to connect the panels for use as a cargo platform . fig9 shows the center deck panel , item 3 . 6 , configured as a table . both items 3 . 3 a and 3 . 3 b are rotated up and locked into place using item 3 . 1 . four legs , items 9 . 1 are then attached and locked into position . fig1 is a multi - section view of the center deck / wheel assembly . it is provided to more clearly show the components that provide rotation and the load carrying members identified in fig3 and fig4 . item 10 . 1 is the wheel spindle . a plate is welded to the spindle and attachment bolts are then used to connect the spindle to the leaf spring . the axle , item 10 . 1 , is double pinned at two points , 3 . 7 c and 3 . 7 d , on each spindle to carry the moment load at each wheel thru the axle item 3 . 1 . fig1 shows an exploded and collapsed view of the locking mechanism at each corner of the center deck assembly and the standard deck panels , items 3 . 6 and 1 . 2 . when assembled , the pivot rod , item 11 . 1 , is spring loaded . the main shaft of 11 . 1 is placed thru hole a . the spring , item 11 . 4 , is loaded inside of the pocket created by item 11 . 3 and a washer , item 11 . 5 , is used to compress the spring , item 11 . 4 . when the spring is compressed the washer is then welded to the end of item 11 . 1 . assembling the components in this manner creates a continuous load on the spring and makes it necessary to exert force to remove item 11 . 1 from hole a . in this condition , end d of 11 . 1 can then be rotated and used as a locking pin in hold c or b as desired and prevents unintentional removal from hole c or d . as an added safety measure , end d of item 11 . 1 may be colored red to indicate it is not engaged . when engaged the red color is not visible thus indicating proper engagement . fig1 shows the pattern of pivot plates ( item 11 . 2 left and 11 . 2 right ) used to lock the panels together and prevent relative axial movement , direction a top panel , direction b bottom panel , when pinned together . since mirrored parts , normally referred to in industry as a right and left hand parts , are used on each corner of the panel , the panels are prevented from moving opposite each other . this prevents improper over loading on the spring detailed in fig1 and adds an additional safety measure to prevent axial movement between panels in the event a locking pin , item 11 . 1 is not sufficiently engaged .
