     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIG. 1 of the invention, shows a main slide track (B1) and a vice slide track (B2) locate on a specific position above the two side panels of the truck funnel, which are intended to allow the canopy (D) slide telescopically. The main slide track (B1) is positioned by a supporting buttress (B3) and a vice slide track (B2) is positioned and supported on the first canopy (D1) of the canopy (D). Another slide supporting buttress (C) is located underneath the intersection of main slide track (B1) and vice slide track (B2). Those serves to allow above-mentioned canopy (D) to slide telescopically and smoothly, between main slide track (B1) and vice track (B2), to make it fixing in the field of vice track when it is closed. 
     A revolving platform (E) is located between two sides of truck body fixer (A), right behind the hood is connected to the first canopy (D1) of the canopy (D). In order to make canopy revolving upwards, sliding horizontally and forwarding to the top of truck hood when canopy (D) is closed. Thus, FIG. 2 shows such a way to save a lot of space for the truck funnel. 
     Referring now also to FIG. 3 shows the exploded diagram of the revolving platform (E), in a great detail and a L-shape. The detail structure of the platform (E) is activated to make sure the canopy (D) revolve upward and slide forward, horizontally; within the body of the platform is cut into a rectangular gap (E1). The revolving platform (E) is connected to the first canopy (D1) of the canopy (D) at a specific position on the other side. 
     An one-way controller (F) is located on horizonal beam, which is fixed onto the truck body fixer (A), said controller (F) can be extended to two ends. Besides, an one way rotating shaft (F1) can be found in each ends of one-way controller (F), which can be rotated straightly or reversely. The above-mentioned one-way controller (F) is one kind of conventional one-way rotating control unit, which will not be described here. 
     As prescribed one-way controller (F), a bolt (F3) is established on the side of the rectangular ingot (F2), facing to rotating shaft (F1). The width of rectangular ingot (F2) is about same as width of the chute-gap (E1), which belongs to revolving platform (E). And bolt (F3) is mounted to a running wheel (F4), which touches the vertical side of the revolving platform (E); wherein , the chute-gap (E1) of the revolving platform (E) can be mounted on rectangular ingot (F2), but revolving platform (E) won&#39;t come out from rectangular ingot (F2), which a positioning screw (F5) is attached, if the rectangular ingot (F2) is welded or touched the end of rotating shaft (F1) by the bolt (F3). 
     Refer to FIGS. 4 and 5, illustrates a means how revolving platform (E), which is connected to rotating shaft (F1). When the canopy (D) is revolved upward by any person through rotating shaft (F1) which works as an axis of rotation, the chute-gap (E1) of the revolving platform (E) will be drive and around the rotating shaft (F1) to revolve by rectangular ingot (F2) at a corresponding angle, such as how it works at a horizonal angle respect to FIG. 6. Depending this step, the canopy (D) is staying at a horizonal level unless it is imposed by a revolving force, the rotating shaft (F1) can be rotated in one-direction under direction limitations of the one-way controller (F) and the weight of the canopy together with its revolving torque, is offset totally by both of rectangular ingot (F2) and the running wheel (F4). 
     The function of revolving platform (E) is revolved upward to a horizonal level and pushed forward; pushed horizontally by a force, the revolving platform (E) will slide forward via both of rectangular ingot (F2) and running wheel (F4), such a achievement is respect to FIG. 7. Thus, the canopy (D) is put on the top of the truck hood as showed in FIG. 2. Once, someone intend to back the canopy (D) to its original position, set the revolving platform (E) slide horizontally first, then make one-way controller (F) rotating to different direction, the canopy (D) will be revolved and back to its original position by a series of contrary procedures. 
     When the position of the canopy (D) is changed from the position showed in FIG. 6 to position showed in FIG. 7, either the center of gravity in the compound set of the canopy (D) or the rotating shaft (F1) is changed to top of the truck hood. By this way, head of the canopy (D) will be downward in accord to rotating direction of rotating shaft (F1); thereby, the canopy (D) will slide horizontally and smoothly, wherein one supporting chute-track (not showed here) is built on the top of the truck hood , which facing to the revolving platform (E). In addition, to set canopy (D) stable on the top of the truck hood, a positioning buckle in any form (not showed here) can be locked the canopy (D) on top of the truck hood. 
     A slide buttress (C) is placed underneath tilt intersection of main slide track (B1)and the vice slide track (B2), slide piece (C1) can be mounted to the lower end of main slide track (B1) or vice slide track (B2); inner dimension of said slide piece-(C1) is almost same as the outer dimension of main slide track (B1) or vice slide track (B2). wherein, two bolts (C12) are inserted into the rectangular chute-gap (C21) of the slide supporting buttress (C), keep the slide piece (C1) sliding on top of supporting buttress (C2) (refer to FIGS. 8 and 9). The main and the vice slide tracks (B1 and B2) will be guide to right position by slide piece (C1); keep the canopy (D) sliding smoothly while it slides on the intersection of main and vice slide tracks B1 and B2 , refer to FIG. 10; the canopy (D) should not be effected even slide piece (C1) touch intersection of main and vice slide tracks B1 and B2. 
     To put down the side panels attached to the truck funnel when canopy (D) is stored at the position showed in FIG. 1, move slide piece (Cl) toward main slide track (B1) to keep it from away vice track (B2), then side panel will be released and put down separately as showed in FIG. 11. 
     Though the intersection of main and vice slide track and B2 should be guided in right way by slide piece (C1), in order to prevent any possible happening that canopy (D) is not sliding smoothly because of the level height of main and vice slide track B1 and B2 is not the same due to the gravity of the canopy (D) or resistance made by descending vice slide track (B2) imposing on slide piece (C1) of slide buttress (C); wherein, vice slide track (B2) is just fixed on one side of the first suspending canopy. An adjusting screw (E2) is located on top of revolving platform (E) as showed in FIG. 3 and 4. The level height of the revolving platform (E) is adjusted by said adjusting screw (E2) when it is screwed inside hole (E3); wherein, end of adjust screw (E2) touches the rotating shaft (F1) of the one-way controller (F), in other words, vice slide track (B2) can be adjusted to same level height of the main slide track (B1) by the screw (E2) accordingly. 
     In a summary, the embodiment of this invention is to keep and stored canopy revolving upwards and sliding horizontally to the top of truck hood, to avoid the stored canopy occupying too much room of the truck funnel and keep loading or unloading conveniently. The foregoing invention has been described with respect to particularly preferred embodiments thereof. However, variations and modifications would be obvious to those skilled in the art.
