Detailed Description of the Invention
[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0024] FIGS. 3, 4 and 5 represent a tailgate of a vehicle according to the first embodiment of the present invention.
[0025] As illustrated in FIG. 3, a body panel 31 comprising a body is coupled with a tailgate inner panel 33 and the tailgate inner panel 33 is coupled thereon to a tailgate outer panel 35. The tailgate outer panel 35 is coupled at an exterior rear side thereof to a tailgate mounted with a glass plate 37.
[0026] The body panel 31 is provided at a tip end thereof with a seal member 39 which is in turn fixed by a strip band 41 in order to seal a gap between the body panel 31 and the tailgate inner panel 33. The strip band 41 is arranged with a hitching jaw to thereby restrain a body panel trim 43.
[0027] A lower tip end between the tailgate inner panel 33 and the tailgate outer panel 35 is closedly adhered by a strip band 45 with a gasket provided therebetween. The strip band 45 serves to fix a seal member 47 for sealing a gap thereof when the tailgate is closed. The strip band 45 is also equipped with a hitching jaw to restrain a tailgate inner panel trim 49.
[0028] The tailgate outer panel 35 is bent at a right side thereof towards the tailgate inner panel 33 to form a bent space which is in turn coupled to hinge means 50 for hinging the glass plate 37. The glass plate 37 is hinged at an upper end thereof to the tailgate outer panel 35 by the hinge means 50. The hinge means 50 includes, as illustrated in FIGS. 4 and 5, a first mounting bracket 51 screwed to an upper surface of the bent space at the tailgate outer panel, a second mounting bracket 53 screwed to an upper side of the glass plate and a hinge axle 55 for hinging the first and second mounting brackets 51 and 53.
[0029] The tailgate outer panel 35 is formed with a hole into which a lower end of the first mounting bracket 51 is inserted. The glass plate 37 is also formed thereon with a hole into which a tip end of the second mounting bracket 53 is inserted.
[0030] The first mounting bracket 51 is formed thereunder with a screw unit 51aand is formed thereon with a female head unit 51bformed with a reentrant unit through which a lower end of the second mounting bracket 53 is inserted. The female head unit 51bis horizontally formed with a hole through which the hinge axle 55 is inserted. The screw unit 51aat the first mounting bracket 51 is inserted into a hole of the tailgate outer panel 35 to thereafter be fixed by a nut 57. At this time, the tailgate outer panel is extended therein with the gasket 44, and coupled by a nut 57.
[0031] The second mounting bracket 53 is formed thereunder with a male head unit 53afor insertion into a reentrant unit of the female head unit 51b, and the male head unit 53 is horizontally formed with a hole through which the hinge axle 55 is inserted.
[0032] The second mounting bracket 53 is formed thereon with a flange 53bfor hitching the glass plate 37 and a screw unit 53c.
[0033] The screw unit 53cof the second mounting bracket 53 is inserted into a hole at the glass plate 37. The hole is again inserted by a bush-type packing member 58 for protection of the glass and by a cap-type nut 59 to secure the second mounting bracket 53.
[0034] The hinge axle 55 of bolt shape is inserted into a hole horizontally formed at the first and second mounting brackets 53 and 55, and combined by a nut 56 to prevent the hinge axle 55 from slipping therefrom.
[0035] The hinge means 50 is assembled by inserting the first mounting bracket 51 into the tailgate outer panel 35, the second mounting bracket 53 into the glass plate, fixing the same and inserting the same into the hinge axle 55.
[0036] The hinge means 50 is provided at two places of the tailgate breadth wise of the vehicle as shown in FIG. 1 (indicated by an arrow).
[0037] In the tailgate thus constructed, when the glass plate 37 is lifted, the tailgate is lifted about the hinge axle 55 as indicated by an imaginary line in FIG. 3.
[0038] FIGS. 6, 7 and 8 define a tailgate of a vehicle according to the second embodiment of the present invention.
[0039] Hinge means 150 for hinging a glass plate 137 according to the second embodiment of the present invention includes, as illustrated in FIGS. 7 and 8, a first mounting pivot 153 disposed at the tailgate outer panel and having a ball 151 and a second mounting pivot 157 disposed at the glass plate 137 and having a journal 155 surface-contacting the ball 151.
[0040] The first mounting pivot 153 has a structure where a right-angled bracket is coupled to the ball 151, and is coupled to the tailgate outer panel 35 by bolt 161 and nut 163. At this time, although the ball 151 is arranged with an extension unit 151aformed with a screw unit to be screwed to the right-angled bracket by a nut 152, it can be screwed without the extension unit or welded.
[0041] The ball 151 is provided at a vertical flange of bracket, and the bolt 161 and the nut 163 are coupled to a horizontal flange of the bracket. The tailgate outer panel 35 is extended therein by gasket 44 and coupled by a nut 163.
[0042] The second mounting pivot 157 is mounted thereunder with the journal unit 155 and the journal unit 155 is provided at an upper end thereof with a screw unit 157a. The screw unit 157ais formed thereunder with a flange 157bfor the glass plate 137 to be inserted and hitched thereat.
[0043] The journal unit 155 is formed with a spherical hole, the shape of which is a little bit larger than a half sphere to prevent the ball from being easily detached therefrom and inserted thereinto. It is preferable to make the journal unit of a material having a predetermined force of resilience. The journal unit 155 only can be made of resilient material or the entire second mounting pivot 157 can be made of resilient material.
[0044] The screw unit 157aat the second mounting bracket 157 is inserted into a hole of the glass plate 137, which is then formed with a bush-type packing member 165 for protection of the glass. A cap-type nut 167 is inserted into the screw unit 157ato secure the second mounting bracket 157.
[0045] The first mounting bracket 153 equipped with the ball 151 is coupled to the tailgate outer panel 35 and the second mounting bracket 157 provided with the journal unit 155 is coupled to the glass plate, where the journal unit 155 is pushed into the ball 151 for simple assembly of the hinge means 150.
[0046] When the glass plate 137, formed at the tailgate of a vehicle according to the second embodiment of the present invention thus constructed, is lifted, the tailgate is lifted about the ball as indicated in an imaginary line in FIG. 6.
[0047] As apparent from the foregoing, there is an advantage in the tailgate of a car according to the present invention in that a glass plate is directly coupled to a tailgate outer panel by a first mounting bracket (or a first mounting pivot) and a second mounting bracket (or a second mounting pivot), such that structure is simple, part involved for assembly thereof are reduced and assembly is easy with manufacturing cost decreased and a beautiful exterior appearance.
