Similarly, the third rotating panel  214  and the fourth rotating panel  216  share a fourth common plane parallel to the plane of the second sidewall  220  when the play structure is in the storage position. Accordingly, the first common plane is generally parallel with the second common plane in the use position, and the third common plan is generally parallel with the fourth common plane in a storage position. Similarly, the first rotating panel  210  and the third rotating panel  214 , forming the third sidewall  219 , and the second rotating panel  212  and the fourth rotating panel  216 , forming the fourth sidewall  221 , are disposed at opposite ends of center beam  222  in the use position. 
     The embodiment illustrated in  FIG.  3    depicts a side view of a main assembly  200 , showing the framing of the second and fourth rotating panels  212  and  216  in the plane of the fourth sidewall  221 . In this view of an illustrated embodiment, it is further shown that the fourth rotating panel  216  comprises a locking arm  236 , which rotates about an axis through the plane of the fourth rotating panel  216 . This is similarly replicated in the plane of the third sidewall  219  (not shown in  FIG.  3   ), with the fourth rotating panel  216  bearing a locking arm  236 . In the illustrated first locking mechanism in the fourth sidewall  221 , this locking arm  236  mates with a lock receiver  242  of the second rotating panel  212 . The locking arm  236  covers a frame lock  234 , mounted on the center frame member  238 , to lock the second and fourth rotating panels  212  and  216  in the use position as shown in  FIG.  3   . Similarly, the first rotating panel  210  possesses a lacking arm  236  as shown in  FIG.  2   , and the third rotating panel  214  has a lock receiver  242 , in the third sidewall  219 .

While the illustrated embodiment depicts this locking arm  236  and lock receiver  242  configuration, other mechanisms, such as pin fasteners, other rotating locking mechanisms, and sliding locks are contemplated for securing the rotating panels  210 ,  212 ,  214 , and  216  in the use position. 
       FIG.  6    depicts an attachment mechanism for ladder assembly  400  according to at least some embodiments, showing how ladder assembly  400  rotatably interfaces with support shaft  408 . Support shaft  408  has a slot or pocket  406  which pivotally receives a ladder fastener  402 . Ladder fasteners  402  also serve to join fastener bracket  404  to ladder side  410 , such that the ladder side  410  can pivot about the axis of the support shaft  408  within the confines of angles allowed by the length of the slot  406 .  FIG.  7    depicts a cross section of this mechanism assembled. 
       FIG.  8    depicts a cross-section of a slide pivoting mechanism according to at least some embodiments, whereby a slide assembly  300 , having a slide wall  312  and a slide surface  314  that are fit around support shaft  310  and are able to pivot about support shaft  310 . The slide assembly  300  further comprises a ladder receiver  316 , such as a c-clamp, that receives and retains the ladder base  414  in the storage position to assist in holding the play structure in the storage position. 
     The embodiment of  FIG.  9    depicts the play structure  100  in a transition state between the use position of  FIGS.  1  and  2    and the storage position of  FIGS.  12  and  13   . As shown by a combination of  FIGS.  5  and  9   , the transition between a use position and a storage position begins by rotating each of the rotating panels  210 ,  212 ,  214 , and  216  about their respective vertical supports  228 . The rotating panels  210 ,  212 ,  214 , and  216  go from being framed by an upper support  230 , a lower support  232 , a vertical support member  228 , and a center frame member  238 , to being framed only by a corresponding rotating panel, the same vertical support member  228 , and support shaft  408  in the case of the first rotating panel  210  and the second rotating panel  212  acting as corresponding rotating panels, and support shaft  310  in the case of the third rotating panel  214  and the fourth rotating panel  216  acting as corresponding rotating panels. These are the positions of each of the four rotating panels in the storage position. 
     As can be seen in both perspective view  FIG.  9    and side view  FIG.  10    of this transition state, when the first, second, third, and fourth rotating panels  210 ,  212 ,  214 , and  216  are in their storage position, the upper supports  230 , lower supports  232 , center beam  222 , and center frame members  238 , and vertical supports  228 , are free to move relative to one another through a series of pivoting connections. Throughout these movements, as depicted by  FIGS.  1 - 3  and  9 - 12   , the first sidewall  218  and second sidewall  220  remain generally equidistant from the center beam  222 , even when moving relative to center beam  222  and one another; further, the first sidewall  218  and second sidewall  220  are closer to the center beam  222  in the storage position than they are in the use position. The first rotating panel  210  and the second rotating panel  212 , in the third common plane parallel to the plane of the first sidewall  218 , and the third rotating panel  214  and the fourth rotating panel  216 , in the fourth common plane parallel to the second sidewall  220 , are disposed opposite one another across the axis of the center beam  222  in the storage position. 
     In the illustrated embodiment, to initiate the transition from the use position to the storage position, an operator will pull upwards on one or more lift handles  226 , which are connected to the pair of upper supports  230 , respectively. The lift handle  226  has a fixed connection to the center member  238 , which further has a fixed connection to a frame lock  234 . The frame lock  234  further connects to the two corresponding lower supports  232 , through angled members  224 . The upward movement of the lift handle  226  draws vertical supports  228 , disposed on opposite sides of a plane perpendicular to center beam  222 , toward one another. Similarly, the slide assembly  300  is drawn toward a ladder assembly  400 .  FIG.  11    depicts this transition, further showing the first sidewall  218  and the second sidewall  220  moving towards one another as the transition progresses. 
     The storage position is depicted in both  FIGS.  12  and  13   . According to at least some embodiments, a roof assembly  500  can be stored within the folded play structure assembly  100 . In the storage position, as shown in both  FIGS.  13  and  14   , a ladder base  414  of the ladder assembly  400  interfaces with a ladder receiver  316  of the slide assembly  300  to lock the play structure  100  in the storage position. 
     In order to prevent unwanted initiation of a transition from the use position to the storage position, the rotating panel recesses  248 ,  250 ,  252 , and  254  receive frame locks  234 . This prevents any relative motion between the upper supports  230 , lower supports  232 , center beam  222 , and center frame members  238 , and vertical supports  228 . In order to keep the first, second, third, and fourth rotating panels  210 ,  212 ,  214 , and  216  in place, such that the corresponding panel recesses  248 ,  250 ,  252 , and  254  interface with the frame locks  234  to prevent this relative motion, a first locking mechanism comprising locking arm  236 , locking arm axis  244 , and lock receiver  242  fastens as depicted in  FIG.  3   . When this first locking mechanism is not fastened, such that locking arm  236  is rotated about locking arm axis  244  to no longer interface with lock receiver  242 , each of rotating panels  210 ,  212 ,  214 , and  216  are free to rotate about vertical supports  228 . 
     In the use position, a first floor member  256  shares a fifth common plane with the center beam  222 . Further, a second floor member  258  shares the same fifth common plane with the center beam  222  and the first floor member  256 . The first floor member  256  is adjacent the first side wall  218 , while the second floor member  258  is adjacent the second side wall  220 . Both the first floor member  256  and the second floor member  258  are adjacent the center beam  222 . In addition to multiple floor members  256  and  258 , the play structure  100  may comprise a plurality of legs  520 , which may include feet  512 . Legs  520  can alternatively be connected in opposing pairs by leg connection assemblies  510 , as depicted in  FIGS.  15  and  16   . 
       FIGS.  15  and  16    depict an alternative embodiment of a play structure  100 .  FIG.  15    shows the structure in the use position, while  FIG.  16    shows the structure in a storage position. In particular, the embodiment shown in  FIG.  15    shows an alternative design of lift handle  226 , as well as an alternative locking mechanism on the fourth sidewall  221 . In this alternative locking mechanism, second rotating panel  212  and fourth rotating panel  216  still comprise panel recesses  250  and  254 , which receive frame lock  234 . In the alternative slide lock assembly  246 , the slide lock assembly  246  is biased towards the second end  237  of the fourth sidewall  221 . In the embodiment shown in  FIGS.  15  and  16   , the slide lock assembly  246  connects with a receiving notch  245 , to prevent rotation of fourth rotating panel  216 . 
     According to some embodiments, the roof assembly  500  includes a canopy  516  as well as a plurality of canopy supports  514 . As shown in  FIG.  5   , canopy supports  514  may fit inside a distal end of vertical supports  228  at each corner of the play structure  100 . Roof assembly  500  can take several shapes, such as the quadrilateral peaked shape shown in  FIG.  5   , rounded profiles, hexagonal profiles, oblong profiles, pentagonal profiles, triangular profiles, and other roof shapes. According to some embodiments, the canopy  516  must be removed before initiating the transition from a use position to a storage position, while in other embodiments the canopy  516  can fold with the rest of play structure  100 . 
     According to some embodiments, the play structure  100  stands roughly 22 to 24 inches tall in the use position of  FIG.  1   , measured from the ground where foot  512  rests to the top of main assembly  200 , however, the play structure may be much larger. In other or the same embodiments, first, second, third, and fourth rotating panels  210 ,  212 ,  214 , and  216  are manufactured from plastics, while upper supports  230 , lower supports  232 , center beam  222 , and center frame members  238 , and vertical supports  228  are manufactured from steel, aluminum, or other suitable structural metals. According to some embodiments, locking arm  236 , locking arm axis  244 , and lock receiver  242  are also manufactured from structural metals, though in other embodiments these components may be manufactured from plastics or composites. In some embodiments having a roof assembly  500 , the canopy  516  is made from abutting plastic panels, while in other embodiments the canopy  516  is made from cloth or composites. 
     A reference to an element in the singular is not intended to mean “one and only one” unless specifically stated, but rather “one or more.” The term “some” refers to one or more. Underlined and/or italicized headings and subheadings are used for convenience only, do not limit the subject technology, and are not referred to in connection with the interpretation of the description of the subject technology. Relational terms such as first and second and the like may be used to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. All structural and functional equivalents to the elements of the various configurations described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and intended to be encompassed by the subject technology. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the above description. 
     Numerous modifications to the present disclosure will be apparent to those skilled in the art in view of the foregoing description. Preferred embodiments of this disclosure are described herein, including the best mode known to the inventors for carrying out the disclosure. It should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the disclosure. 
     Several alternative embodiments and examples have been described and illustrated herein. A person of ordinary skill in the art would appreciate the features of the individual embodiments, and the possible combinations and variations of the components. A person of ordinary skill in the art would further appreciate that any of the embodiments could be provided in any combination with the other embodiments disclosed herein. Additionally, the terms “first,” “second,” “third,” and “fourth” as used herein are intended for illustrative purposes only and do not limit the embodiments in any way. Further, the term “plurality” as used herein indicates any number greater than one, either disjunctively or conjunctively, as necessary, up to an infinite number. Additionally, the term “having” as used herein in both the disclosure and claims, is utilized in an open-ended manner. 
     As used herein, the phrase “at least one of” preceding a series of items, with the terms “and” or “or” to separate any of the items, modifies the list as a whole, rather than each member of the list (i.e., each item). The phrase “at least one of” does not require selection of at least one item; rather, the phrase allows a meaning that includes at least one of any one of the items, and/or at least one of any combination of the items, and/or at least one of each of the items. By way of example, the phrases “at least one of A, B, and C” or “at least one of A, B, or C” each refer to only A, only B, or only C; any combination of A, B, and C; and/or at least one of each of A, B, and C. 
     To the extent that the term “include,” “have,” or the like is used in the description or the claims, such term is intended to be inclusive in a manner similar to the term “comprise” as “comprise” is interpreted when employed as a transitional word in a claim. Phrases such as an aspect, the aspect, another aspect, some aspects, one or more aspects, an implementation, the implementation, another implementation, some implementations, one or more implementations, an embodiment, the embodiment, another embodiment, some embodiments, one or more embodiments, a configuration, the configuration, another configuration, some configurations, one or more configurations, the subject technology, the disclosure, the present disclosure, other variations thereof and alike are for convenience and do not imply that a disclosure relating to such phrase(s) is essential to the subject technology or that such disclosure applies to all configurations of the subject technology. A disclosure relating to such phrase(s) may apply to all configurations, or one or more configurations. A disclosure relating to such phrase(s) may provide one or more examples. A phrase such as an aspect or some aspects may refer to one or more aspects and vice versa, and this applies similarly to other foregoing phrases. 
     A reference to an element in the singular is not intended to mean “one and only one” unless specifically stated, but rather “one or more.” The term “some” refers to one or more. Underlined and/or italicized headings and subheadings are used for convenience only, do not limit the subject technology, and are not referred to in connection with the interpretation of the description of the subject technology. Relational terms such as first and second and the like may be used to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. All structural and functional equivalents to the elements of the various configurations described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and intended to be encompassed by the subject technology. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the above description. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for.” 
     While this specification contains many specifics, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of particular implementations of the subject matter. Certain features that are described in this specification in the context of separate embodiments can also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination. 
     The title, background, brief description of the drawings, abstract, and drawings are hereby incorporated into the disclosure and are provided as illustrative examples of the disclosure, not as restrictive descriptions. It is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. In addition, in the detailed description, it can be seen that the description provides illustrative examples and the various features are grouped together in various implementations for the purpose of streamlining the disclosure. The method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the claims reflect, inventive subject matter lies in less than all features of a single disclosed configuration or operation. The claims are hereby incorporated into the detailed description, with each claim standing on its own as a separately claimed subject matter. 
     It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein. Accordingly, while the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention and the scope of protection is only limited by the scope of the accompanying Claims. 
     Further, the claims are not intended to be limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims and to encompass all legal equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirements of the applicable patent law, nor should they be interpreted in such a way.
