Brief Description of the Drawings The features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The invention, together with further objects and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawings, in the several figures of which like reference numerals identify like elements and in which: Figure 1 sets forth a perspective view of a roll- up halfpipe for miniature toy skateboard constructed in accordance with the present invention; Figure 2 sets forth a perspective assembly of the roll-up halfpipe of Figure 1; Figure 3 sets forth a partial assembly view of • the present invention roll-up halfpipe in its carrying or storage configuration; Figure 4 sets forth a side elevation view of a collapsible lateral support member utilized in the. present invention roll-up halfpipe in its folded position having its extended position shown in dashed- line; Description of the Preferred Embodiment Figure 1 sets forth a perspective view of a miniature halfpipe constructed in accordance with the present invention and generally referenced by numeral 10. Halfpipe 10 is fabricated of an appropriate miniature size to accommodate a fingerboard 60 constructed to replicate a conventional skateboard. Halfpipe 10 includes a pair of sideframes 11 and 12 positioned in a generally parallel arrangement. Sideframes 11 and 12 are substantially identical in fabrication and in accordance with the present invention are capable of being collapsed or folded to facilitate the compact storage configuration set forth below in Figure 3. More specifically, sideframe 11 includes a pair of siderails 20 and 23 pivotally joined at a hinge 22. Sideframe 11 further includes a pair of vertically extending endstands 30 and 31 each having upper ends 32 and 33 respectively. Endstand 30 is pivotally secured to the outer end of siderail 20 by a hinge 21 and is pivotable in the directions indicated by arrows 26. Similarly, endstand 31 is pivotally secured to the outer end of siderail 23 by. a hinge 24 and is pivotable in the directions indicated by arrows 25. As is better seen in Figure 2, sideframe 12 which is substantially identical to sideframe 11 includes a pair of siderails 45 and 46 joined at a hinge 47. By way of further correspondence, sideframe 12 includes a pair of endstands 40 and 42 pivotally secured to siderails 45 and 46 respectively by hinges 49 and 48. Endstands 40 and 42 defines respective upper ends 41 and 43 (better seen in .Figure 2) . Halfpipe 10 further includes a pair of generally planar platforms 50 and 52 defining respective grooves 51 and 53. By conventional attachment means (seen in Figure 2) platform 50 is secured to ends 32 and 43 of endstands 30 and 42 while platform 52 is secured to ends 33 and 41 of endstand 31 and 40. Halfpipe 10 further includes a flexible sheet 35 preferably formed of a slightly flexible resilient material such as thin plastic or the like. The essential characteristic of sheet 35 is the possession of sufficient strength and resilience to maintain a suitable ramp surface upon halfpipe 10 while being nonetheless sufficiently flexible to be curled or rolled into the closed configuration shown in Figure 3. Sheet 35 defines a pair of edges 36 and 39 at opposite ends thereof and a pair of side edges 37 and 38. Edges 36 and 39 are received within grooves 51 and 53 of platforms 50 and 52 respectively. Thus, in the assembled configuration shown in Figure 1, halfpipe 10 forms a stand alone generally rigid structure upon which the user is able to roll fingerboard 60 back and forth in the directions indicated by arrows 16 and 17 as the user places a finger 15 upon the upper surface of the fingerboard. The user then manipulates fingerboard 16 in accordance with typical skateboard maneuvers and stunts. Figure 2 sets forth a perspective assembly view of halfpipe 10 together with endcaps 61 and 62. As described above, halfpipe 10 includes a pair of substantially identical sideframes 11 and 12 joined by a pair of platforms 50 and 52 in a snap-fit attachment. Sideframe 11 includes a pair of siderails 20 and 23 joined by a hinge 22 together with a pair of endstands 30 and 31 joined to siderails 20 and 23 by hinges 21 and 24 respectively. Endstands 30 and 31 defines respective upper ends 32 and 33. Ends 32 and 33 are configured to snap-fit into sockets formed in platforms 50 and 52. Similarly, sideframe 12 includes a pair of siderails 45 and 46 joined by a hinge 47 together with a pair of endstands 40 and 42 pivotally secured to siderails 45 and 46 by hinges 49 and 48. Endstands 40 and 42 define upper ends 41 and 43 configured to snap- fit attach to platforms 52 and 50 respectively. Thus, the combination of sideframes 11 and 12 together with platforms 50 and 52 provides the supporting strength for halfpipe 10 in the open or extended configurations thereof shown in Figure 2. Halfpipe 10 further includes a resilient flexible sheet 35 preferably formed of a somewhat rigid material such as thin plastic or the like. Sheet 35 defines edges 36 and 39 at each end thereof together with side edges 37 and 38. The material thickness selected for sheet 35 is chosen to provide sufficient rigidity to span the space between sideframes 11 and 12 to facilitate the above described fingerboard play while concurrently being sufficiently flexible to be rolled into the closed configuration shown in Figure 3. Endcaps 61 and 62 are utilized in combination with sheet 35 in its rolled configuration shown in Figure 3 to provide closure of the rolled sheet structure. Sheet 35 is secured at edges 36 and 39 by grooves 51 and 53 formed in platforms 50 and 52. With edges 36 and 39 secured to platforms 50 and 52, the resilience and strength of sheet 35 causes sheet 35 to be pressed against the upper edges of side frames 11 and 12 which support edges 37 and 38 respectively of sheet 35. In accordance with an important aspect of the present invention, halfpipe 10 may be disassembled and conveniently packed and carried in the manner shown in Figure 3. The disassembly of halfpipe 10 is carried forward by removing the snap-fit attachments of platforms 50 and 52 upon sideframes 11 and 12. This releases sheet 35 and sideframes 11 and 12. Thereafter, sideframe 11 is collapsed by pivoting siderail 23 about hinge 22 to bring siderails 20 and 23 into a parallel side-by-side arrangement such as that shown in Figure 4 in solid-line representation. Thereafter, endstands 30 and 31 are pivoted about hinges 21 and 24 respectively in the directions indicated by arrows 26 and 25 to configure sideframe 11 in its fully collapsed position as shown in Figure 4 in solid-line representation. Sideframe 12 is similarly collapsed by pivoting siderails 45 and 46 about hinge 47 and pivoting endstands 40 and 42 about hinges 49 and 48. At this point, the user simply rolls sheet 35 in the manner shown in Figure 3 to form a cylindrical body and places one end thereof into either of endcaps 61 and 62. Sideframes 11 and 12 in their collapsed position together with platforms 50 and 52 may then be placed within the interior defines by sheet 35 in its rolled configuration (seen in Figure 3). The final closure is accomplished by simply utilizing the remaining one of endcaps 61 or 62 to captivate the open end of rolled sheet 35 as is also better seen in Figure 3. Figure 3 sets forth a perspective assembly view of halfpipe 10 in its closed configuration. As can be seen, sheet 35 having edges 36 and 39 as well as side edges 37 and 38 has been rolled into a generally cylindrical configuration after which endcap 61 is secured upon edge 38. In its rolled configuration, sheet 35 defines an interior cavity 55 within which the structural elements of halfpipe 10 such as sideframes 11 and 12 together with platforms 50 and 52 may be received. As a final step, endcap 62 is secured upon edge 37 and the end portion of rolled sheet 35 to complete closure of halfpipe 10. The resilience of sheet 35 produces a sufficient spring force urging sheet 35 against its rolled configuration to maintain a secure attachment of endcaps 61 and 62. In this manner, the present invention halfpipe may be conveniently carried or stored. The assembly of halfpipe 10 into the open or operative configuration shown in Figure 1 is carried forward in a generally reverse process to that described above. Thus, endcaps 61 and 62 are removed from sheet 35 and the structural components of halfpipe 10 such as sideframes 11 and 12 and platforms 50 and 52 are retrieved from the interior of sheet 35 and opened to their extended configurations shown in Figures 1 and 2. Thereafter, sheet 35 is positioned upon sideframes 1.1 and 12 and platforms 50 and 52 are snap-fitted to captivate sheet 35 in the manner shown in Figure 1. Figure 4 sets forth a side elevation view of sideframe 11 illustrating its collapsed configuration in solid-line representation. Sideframe 11 is also shown in dashed-line configuration in its extended configuration. In the collapsed configuration shown in Figure 4, sideframe 11 includes siderails 20 and 23 pivoted together at hinge 22 in the directions indicated by arrows 27. Further, endstands 30 and 31 having ends 32 and 33 are shown pivoted to their collapsed position. Sideframe 11 is returned to its extended configuration by pivoting siderails 20 and 23 about hinge 22 to move siderail 23 to the dashed-line position shown. Sideframe 11 is fully extended by pivoting endstands 30 and 31 about hinges 21 and 24 in the directions indicated by arrows 28 and 29 to the fully extended positions shown in dashed-line representation . It will be understood that the structure of sideframes 11 and 12 are substantially identical and thus the descriptions and figures set forth herein will be understood to apply equally well and be equally descriptive of the structure of sideframe 12. Thus, sideframes 11 and 12 are capable of configuration in a collapsed position suitable for insertion into sheet 35 in the manner shown in Figure 3 or to an extended configuration suitable for use as supporting structure for sheet 35 in the manner shown in Figure 1. What has been shown is a novel roll-up halfpipe for use in combination with miniature toy skateboards or "fingerboards" which is collapsible to provide convenient storage and carrying in an extremely compact and interesting configuration. The apparatus is suitable for fabrication using conventional molded plastic elements and is relatively simple to assemble and disassemble by younger children. While particular embodiments of the invention • have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
