Abstract:
An automotive double folding tailgate constructed to doubly fold a lid panel and a glass to position same toward floor of automobile body enabling making a cargo loading space available, the tailgate comprising: a lid panel supported on a floor of automobile body via a pivot unit, and a glass foldable at a lower end thereof via a folding unit mounted at an upper part of the lid panel and releasably mounted to a roof panel at an upper end thereof via a locking unit.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an automotive double folding tailgate, and more particularly to an automotive double folding tailgate adapted to be folded and unfolded downward to enable to open a cargo loading space. 
     2. Description of the Prior Art 
     Generally, an automobile is formed at the rear part thereof with an open space for loading cargoes. In case of an automobile with emphasis more on loading cargoes, the automobile adopts a tailgate folding upward of the body thereof and minimizes obstacle at the entrance of cargo loading space (W) to thereby enable to expedite loading of cargoes. 
     The tailgate thus described generally includes, as illustrated in FIGS. 1 and 2, a lid panel  1  having a glass  2 , gas lifters  3  and  3 ′ so mounted as to support the lid panel at both lateral surfaces of automobile body and to keep an opened position of the lid panel  1  when the lid panel  1  hinged at roof panel (R) is lifted upward, and a latch assembly  5  mounted underneath the lid panel  1  to be coupled to a striker installed at the automobile body to function as locking action. 
     Reference numeral  4  identifies a key cylinder for manipulating the latch assembly by way of an automobile key. 
     there is an advantage in the lifting tailgate thus described in that a relatively spacious cargo loading space (W) can be obtained in comparison to a general passenger car and cargo loading is easy but there is a disadvantage in that the lid panel  1  having a radius of gyration covering the entire cargo loading space (W) equipped with glass  2  is lifted upward to protrude backward of the automobile, posing an obstacle to cargo loading and being unable to be lifted in a very narrow space at the back of the automobile. 
     SUMMARY OF THE INVENTION 
     The present invention is disclosed to solve the aforementioned problems and it is an object of the present invention to provide an automotive double folding tailgate adapted to fold a lid panel and glass to allow being positioned toward the floor inside the automobile, thereby posing no obstacle to loading big cargo and enabling opening a cargo loading space easily even in a very narrow space at the back of the automobile. 
     In accordance with the object of the present invention, there is provided an automotive double folding tailgate, the tailgate comprising: 
     a lid panel supported on the floor of an automobile body via pivot means; and 
     a glass foldable at a lower end thereof via folding means mounted at an upper part of the lid panel and releasably mounted to a roof panel at an upper end thereof via locking means.

     DETAILED DESCRIPTION OF THE INVENTION 
     Now, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
     FIG. 3 is a schematic structural drawing of a double folding tailgate according to the present invention, where the tailgate includes a lid panel  1  supported on a floor (F) of automobile body via pivot means  10 , and a glass  2  foldable at a lower end thereof via folding means  20  mounted at an upper part of the lid panel  1  and releasably mounted to a roof panel (R) at an upper end thereof via locking means  30 . 
     The pivot means  10  includes a fixation bracket  11  fixed the floor (F) of the automobile body, a connection bracket  12  fixed to a lower end of the lid panel  1  and a hinge pin  13  coupled between the two brackets  11  and  12  and functioning as a pivot shaft axle when the lid panel  1  is turned backward into interior of the automobile. 
     Furthermore, the folding means  20  installed in pairs, each spaced out at a predetermined interval, for stably folding the glass  2  toward the lid panel  1  includes, as shown in FIG. 4, a hinge arm having a “L” shape with one end thereof being fixed via a fixation bolt  24  to a groove formed at a fixation member  2   a  for supporting the glass  2 , and a hinge base  22  to which a fixation end  21   a  of the hinge arm  21  is fixed via a pivot pin  23  where the hinge base  22  is fixed to the lid panel  1  by the fixation bolt  25 . 
     At this location, the hinge base  22  is formed with a depressed bent part  22   a  for allowing the hinge arm  21  to rotate therein freely. 
     Furthermore, a fixation bolt  24  is mounted by a washer  24 ′ and an insert  24 ″ as illustrated in FIG. 8 while the pivot pin  23 , as shown in FIG. 9, is equipped with a bushing  23 ′ to reduce friction during rotation between the fixation end  1   a  of the hinge arm  21  and the bent part  22   a  of the hinge base  22  and to be stably supported. 
     Meanwhile, locking means  30  installed in pairs, each spaced out at a predetermined interval, for stably holding the glass  2  to the roof panel (R) includes a hook  31  having a housing  31   a  for receiving a hitching end  31   b  fixed to the glass  2  and functioning as a lock via resilience, and a locker  32  coupled to the hook  31  and mounted to the roof panel (R) for fixing the glass  2 . 
     Now, operation of the present invention will be described. 
     First of all, as illustrated in FIG. 7, when the hitching end  31   b , comprising the hook  31  of the locking means  30  for fixing the glass  2 , being equipped on the upper ends of the roof panel (R) and the glass  2 , each being coupled, is lowered, spring is pressed to make the hitching end  31   b  detached from the locker  32 . 
     Successively, when the glass  2  deprived of restraining force of locking means  30  is held to be moved to the lid panel  1 , the glass  2  is folded onto the lid panel  1  via the folding means  20  coupling the lid panel  1  and the glass  2 . 
     In other words, the hinge arm  21  of the folding means  20  is rotated toward the lid panel  1  via the pivot pin  23  to allow the glass  2  to be fully folded and received into a receiving space la of the lid panel  1 , as illustrated in FIG.  3 . 
     At this time, it should be apparent that a cushioning pad of soft material such as sponge mounted at the receiving space  1   a  of the lid panel  1  absorbs the shock of the glass  2 . 
     Successively, when the lid panel  1  where the glass  2  is accommodated is turned backward into the interior of the automobile via hinge pin  13  of pivot means  10 , the lid panel  1  is folded onto the floor (F) of the automobile body to open the cargo loading space (W). 
     As a result, no hindrance is caused by the lid panel  1  and the glass  2  when bulky cargo is loaded into the cargo loading space (W), enabling to load the bulky cargo, and even if space behind the rear of the automobile is narrow, it is easy to open and close the lid panel  1 . 
     Meanwhile, when the lid panel  1  folded onto the floor (F) of automobile body thus described is to be closed again, the lid panel  1  is erected via the hinge pin  13  of pivot means  10 , and the glass  2  is held to be lifted toward the roof panel (R), and the hitching end  31   b  of hook  31  secured to the glass  2  of the locking means  30  is inserted into locker  32  fixed to the roof panel (R) to thereby be locked thereat. 
     As apparent from the foregoing, there is an advantage in the automotive double folding tailgate thus described in that a tailgate is folded into interior of the automobile body to open cargo loading space (W), such that hindrance caused by a lid panel opened upward and protruded backward when cargo is loaded or unloaded can be removed, thereby enabling to easily open and close the tailgate even in a narrow space at the rear of the automobile.
