[0002]

2. Description of the Related Art As shown in FIG. 14, a hood 3 of a hood truck 1 has a door hood 4 provided on an upper portion of a door panel 2 and a roof hood 6 constituting a roof or the like. Conventionally, the above trolley 1
15 and 16, the door door contact structure has a very low sealing effect because the hood itself constitutes the sealing surface.

FIG. 15 shows a first example of a door door contact structure which has been conventionally used.
The L section is shown. The conventional first door door contact structure 60 shown in FIG. 15 includes a first hood bone 61 fixed to the door panel 2 (shown in FIG. 14) and a second hood bone fixed to the vehicle body 7 (shown in FIG. 14). The roof frame 62 and the roof frame 63 are provided. A part 4a (end portion) of the door hood 4 is wound around the first hood 61. A hood cloth 64 is wound around the second hood frame 62, and a part 64a of the hood cloth 64 positioned on the outer side portion 62a when the vehicle body is mounted and a part 6a of the roof hood 6 facing the outer side portion 62a. Is sewn with the suture thread 65,
The second hood 62 and the roof hood 6 are fixed to each other.
The roof frame 63 is formed in a frame shape along the inner side of the roof hood 6, and both ends thereof are fixed to the vehicle body 7 so that the roof hood 6 is supported with appropriate tension. The roof frame 63 and the second top frame 62 are fixed to each other by bolts or the like.

The first conventional door door contact structure 60 constructed as described above is wound around the part 4a of the door hood 4 wound around the first hood 61 and the second hood 62. A sealing surface S is formed by the part 64b of the hood cloth 64 mounted. Therefore, the end portion 64c of the hood cloth 64 wound around the second hood bone 62 due to variations in the construction of the hood bones 61 and 62, vibration of the vehicle body itself during traveling, etc. is shown by the two-dot chain line in the figure.

7 and the door hinge and the sealing surface formed on the longitudinal bone 16 on the opposite side.

Regarding the sealing surface formed on the vertical frame 15 on the door hinge side shown in the section JJ, when the door is closed, first, as shown in FIG. 10A, the door is closed with the hinge center 8a as the center. A part 23b of the hood cloth 23 wound around the longitudinal bone 15 and a part 40a of the weather strip 40 are brought into contact with each other by the rotation O1 in the direction. The rib 43, which receives a tensile load by the vertical bones 15 and the like, is made of an elastic material such as rubber, and therefore, as shown in FIG.
The door panel 2 is closed while 3b and the part 40a of the weather strip 40 are in contact with each other. Therefore, the weather strip 40 is wound around the longitudinal bone 15 in the direction of the chain double-dashed line Q in the figure, and together with the bending deformation of the ribs 43, the weather strip 40 gives a proper reaction force, and the weather strip 40 is shown in FIG. Thus, the sealing surface 50 is formed on the door outer peripheral side 15c through the hood cloth 23.

Since the first hollow portion 44 and the second hollow portion 45 compressed in one direction by the vertical bone 15 are made of an elastic material such as rubber, the restoring force as shown in FIG. The f1 and f2 act on the vertical bones 15 from the outer peripheral side of the door to the inner peripheral side thereof, and from the inner side of the vehicle to the outer side of the door.
A sealing effect is exhibited between 0 and. At this time, since the hood cloth 23 wound around the first hood bone 12 (longitudinal bone 15) is a cloth, some wrinkles and the like are generated when the sealing surface 50 is formed, but the sealing surface 50 is wide and therefore creases are formed. Has a very small effect.

Regarding the sealing surface formed on the horizontal frame 17 and the vertical frame 16 on the side opposite to the door hinge shown in the section I-I, when the door is closed, first, as shown in FIG. By moving the door in the direction O2, a part 4c of the end 4a of the door hood 4 wound around the lateral frame 17 of the first hood 12 and the part 40b of the weather strip 40 come into contact with each other. Unlike the door hinge side, the sealing surface 50 is formed on the interior side 17c of the door without winding the weather strip 40, as shown in FIG. 11B.
Then, the rib 4 compressed in one direction by the lateral bones 17 and the like
Since 3 is made of an elastic body such as rubber, as shown in FIG. 11B, the restoring force g acts on the lateral ribs 17, acting from the inside of the vehicle to the outside of the vehicle, to the lateral bones 17 of the first top bone 12, and the like. A sealing effect is exhibited with the weather strip holder 30. At this time,
Since the sealing surface is wide like the door hinge side, the influence of wrinkles on the end 4a of the door hood 4 is very small.

As described above, since the door panel 2 is closed by the rotation around the door hinge, first, as shown in FIG.
The sealing surface 50 is formed from the vertical frame 15 on the door hinge side shown in (A) to (C), and the sealing surface 50 is gradually formed to the horizontal frame 17 as shown in FIGS. 11 (A) to (B). Further, a sealing surface 50 is continuously formed on the vertical bone 16 on the side opposite to the door hinge. Therefore, the sealing surface 50 is
As shown by the two-dot chain line in the vertical frame 15 on the door hinge side, on the door outer peripheral side 15c, and on the horizontal frame 17 and the vertical frame 16 on the side opposite to the door hinge, on the vehicle inner side 17c of the door,
Even in the corner portion where both seal surfaces 50 are connected, the seal surface 50 is formed smoothly and continuously. This corner portion is a portion where wrinkles are likely to occur on the hood cloth forming the sealing surface 50. As described above, since the wide sealing surface 50 smoothly continues at the corner portion, the wrinkles of the hood cloth adversely affect the sealing effect. It can be avoided. Also,
As shown in FIG. 10 (C) and FIG. 11 (B), the restoring force f1, f2, g of the weather strip 40 is applied to the sealing surface 50.
Etc. act to exert a sealing effect between the first hood bone 12 and the weather strip holder 30.

Further, as shown in FIGS. 1 and 2, the screw 2
The weather strip holder 30 is clamped and fixed by pinching the part 9b of the hood cloth 9 wound around the weather strip holder fixing surface 22 of the second hood bone 20 by means of 1. Since they are not directly adjacent to each other, the capillary phenomenon does not occur, and therefore the weather strip holder 30
A sealing effect is exerted between the second hood and the second hood bone 20.

As described above, the weather strip holder 30 is crimped and fixed through the part 9b of the hood cloth 9 wound around the second hood bone 20 so that the sealing effect is exerted and the door panel is obtained. The space between the first hood bone 12 fixed to 2 and the weather strip holder 30 is sealed by an elastic body such as a weather strip 40,
Moreover, since the weather strip 40 forms a sealing surface between the weather strip 40 and the arcuate surface 13 of the first hood bone 12, the vertical frame 15 on the door hinge side is on the outer peripheral side 15c of the door, and the horizontal frame 17 and the door hinge are not. In the vertical bone 16 on the opposite side, the sealing surface 50 is formed smoothly and continuously with the vehicle inner side 17c of the door, and the sealing effect can be enhanced.

[0036]

According to the invention described in claim 1 , a seal surface is formed between the weather strip holder and the arc surface of the first hood bone formed of a round pipe , and the vertical bone seal on the door hinge side is formed. Since the surface and the horizontal bone and the sealing surface of the vertical bone on the side opposite to the door hinge can be smoothly continuous, wrinkles or the like generated at the end of the door hood wound around the hood will adversely affect the sealing effect. Is avoided.

Therefore, it is possible to reduce the influence of the vibration of the vehicle body, the opening and closing of the door, the variation of the construction of the roof frame, and the like, and the sealing effect is not lost even while the vehicle is running, and a good sealing effect is obtained. It is possible to maintain.
