る。[Detailed description of the invention] (Field of industrial application) The present invention relates to a stepped roof for automobiles, and in particular,
The present invention relates to a stepped roof for an automobile, which is configured such that two arch-shaped roofs are connected in the longitudinal direction of the vehicle.

る。(Prior Art) Some cab-over type automobiles are equipped with a stepped roof in order to lower the vehicle height as much as possible. This stepped roof consists of two arch-shaped roofs connected in the front and back direction. Instead of structuring the roof into one tall dome shape to provide rigidity, a recess is provided in the center of the roof, and the roof is constructed in the same way. It is designed to ensure the rigidity of the

段付ルーフを備えるのが通常である。 Further, a double-cabin type vehicle in which two cabins are arranged in the front and rear is usually provided with a stepped roof formed by connecting two single-cab arch-shaped roofs in the front and rear.

つて連続するように形成されている。 Also in such a stepped roof, a group of reinforcing beads are formed like a general roof. This bead group consists of a plurality of beads formed to extend in the longitudinal direction of the vehicle, and each bead is formed to be continuous over the entire length from the front end to the rear end of the roof.

という欠点が生じている。(Problem that the invention aims to solve) However, with such a stepped roof,
Rainwater, car wash water, etc. tend to accumulate in the recess in the center of the roof, and the accumulated water is often blocked by the continuous bead mentioned above and cannot be drained out from the side of the vehicle. . When the vehicle suddenly stops or accelerates, the stored water may flow out in the longitudinal direction of the vehicle, causing safety problems such as impairing visibility. To solve this problem, some vehicles have lowered the rear roof, but this has the disadvantage of insufficient head space.

（問題点を解決するための手段）上記問題点を解決するため、本考案は、ルーフ

側方向に流出されるようにしている。(Means for Solving the Problems) In order to solve the above problems, the present invention divides the bead group for the roof separately into the front side and the rear side and forms them discontinuously. The groups are offset from each other in the left-right direction of the vehicle, and are formed so as to overlap each other over a predetermined length at the boundary between the front and rear roofs, thereby reducing the water retention space at the bottom of the roof. , and the water stored there flows out to the left and right of the vehicle by threading along the bead ends.

（実施例）以下、本考案の実施例を図面に基づいて詳細に
説明する。(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

第１図におよび第２図に示すように、段付ルー

凹部が形成されるようになつている。 As shown in FIGS. 1 and 2, the stepped roof includes a front roof 1 having an arch shape;
The rear roof 2 also has a single arch shape, and a recess is formed at the boundary between the two roofs 1 and 2.

そして、両ルーフ１，２上には、それぞれ別個

位置をずらして配置されており、両側の各ビード
が交互に配列されるようになつている。 Separate reinforcing bead groups 3 and 4 are discontinuously formed on both roofs 1 and 2 so as to be separated from each other. Both bead groups 3 and 4 consist of a plurality of beads extending in the longitudinal direction of the vehicle, and each bead is provided at predetermined equal pitch intervals. And bead group 3 on the front side
The beads in the rear bead group 4 and the beads in the bead group 4 on the rear side are arranged with their positions shifted from each other in the left-right direction of the vehicle (vertical direction in Figure 1), so that the beads on both sides are arranged alternately. It's getting old.

さらに、前方側の各ビードと後方側の各ビード

る。 Furthermore, each bead on the front side and each bead on the rear side are formed so as to wrap around each other over a predetermined length at the boundary between the front and rear roofs 1 and 2, and the reinforcement of the roof boundary is improved. It's starting to become easier. Further, in this case, the terminal end of the front bead group 3 and the terminal end of the rear bead group 4 are set at approximately the same height, and furthermore, these bead terminal ends are located at the roof which is the intermediate part between them. It is set to be as flush as possible with the bottom.

る。 In a stepped roof with this configuration,
The front bead group 3 and the rear bead group 4 are formed so as to wrap around each other at the roof boundary and alternately extend toward the other, so that the height of the general roof surface at the roof boundary is the same as the bead forming area. , and the water storage space can be reduced. Particularly, as in the above embodiment, if the terminal ends of the bead groups 3 and 4 on both sides are set at approximately the same height as the bottom of the roof, the water pooling space can be almost eliminated.

る。 Also, even if water accumulates at the roof boundary, the water will flow in the left-right direction of the vehicle between the front bead end and the rear bead end, as shown by the arrows in Figure 1. and is ejected from the side of the vehicle.

なお、このようにビードを前方側ビード群３と
後方側ビード群４に分割するようにしても、両側

ちルーフ境界部分は十分に補強されている。 Note that even if the beads are divided into the front bead group 3 and the rear bead group 4 in this way, the beads on both sides are formed so as to overlap each other, so the boundary between both bead groups 3 and 4 is The section, namely the roof border, is fully reinforced.

両の側部から良好に排出させることができる。(Effects of the invention) As described above, the stepped roof for automobiles according to the invention reduces the water retention space at the boundary of the roof, and the front roof and the rear roof are designed to form a water flow path. Since separate beads are formed alternately and discontinuously, almost no water stays at the roof boundary, and even if water does stay, the stored water flows over the bead ends on both sides. It can be easily discharged from the side of the vehicle.
