「考案の利用分野」
本考案は自動車用ルーフパネルの構造に係り、
特に防水性などの向上を図つたものに関する。[Detailed description of the invention] "Field of application of the invention" This invention relates to the structure of an automobile roof panel.
In particular, it relates to products with improved waterproof properties.
「従来技術」
従来、自動車用ルーフパネルとして種々の改良
がなされているが、特にルーフパネルに開閉自在
の窓を設けたものにおいては、窓を構成する開口
が上方向を向いているため窓の隙間から雨水が侵
入しやすく、防水性に充分な配慮を払う必要があ
る。``Prior Art'' Various improvements have been made to automobile roof panels in the past, but in particular in roof panels with windows that can be opened and closed, the openings that make up the windows face upwards, making it difficult for the windows to open. Rainwater easily enters through the gaps, so careful consideration must be given to waterproofing.
例えば特願昭59−104083号出願の明細書及び図
面に記載されたハイルーフ型乗用車のルーフパネ
ルは、第３図及び第４図に示すような構造をして
いる。 For example, the roof panel of a high-roof type passenger car described in the specification and drawings of Japanese Patent Application No. 59-104083 has a structure as shown in FIGS. 3 and 4.
すなわちハイルーフワゴンａのルーフパネルｂ
には、その前方左右にそれぞれ開口ｃが設けられ
ており、この開口ｃの側部にヒンジｄを介して開
閉自在に取り付けた窓部材ｅによつて、開口ｃを
開閉自在となしている。なおｆはこの場合、嵌め
殺し式の天井窓である。 In other words, roof panel b of high roof wagon a
is provided with an opening c on the front left and right sides thereof, and the opening c can be opened and closed by a window member e attached to the side of the opening c via a hinge d so as to be openable and closable. Note that in this case, f is a ceiling window that can be fitted into the ceiling.
上記のような窓部材ｅは、例えば第４図に示す
如くガラス、強化プラスチツク、もしくは鉄板な

閉じた時、窓部材ｅの外縁部ｉの下面が当接し、
窓部材ｅと端縁部ｇとの間の隙間ｊから雨水が車
室内へ侵入しないように構成されている。 The window member e described above is made of glass, reinforced plastic, or a steel plate, for example, as shown in FIG. The edge g is slightly depressed toward the interior of the vehicle, and when the window member e is closed, the lower surface of the outer edge i of the window member e comes into contact with the sealing member h disposed on the upper surface of the edge g.
It is configured to prevent rainwater from entering the vehicle interior through the gap j between the window member e and the edge portion g.
また端縁部ｇは開口ｃを形成するために打ち抜
かれた部分の外枠部であるから強度的に非常に弱
いため、そのままでは窓部材ｅによる押し付け力
に耐えることができないので、その裏面に補強用
の鉄板ｋをスポツト溶接により固定し、窓枠部分
の変形を防止している。 In addition, since the edge part g is the outer frame part of the part punched out to form the opening c, it is very weak in strength, and cannot withstand the pressing force of the window member e as it is, so A reinforcing iron plate k is fixed by spot welding to prevent the window frame from deforming.
しかしながら上記のようなシール部材ｈのみに
よるシール作用では、雨水の侵入を完全に制限す
ることが困難であり、特にルーフパネルの平坦部
において上記のように開口ｃの端縁部ｇが車室内

によつて囲まれる空間ｌが一種の水たまりのよう
になり、ここに滞留した水がシール部材ｈの存在
にも関わらず、端縁部ｇに沿つて車室内の方向へ
滲み込んでくる。 However, with the sealing action of only the sealing member h as described above, it is difficult to completely restrict the intrusion of rainwater, and especially in the flat part of the roof panel, the edge g of the opening c is located inside the vehicle interior. In a structure as shown in the fourth figure in which the window member e is sunken in the direction, the edge g and the seal member h, and further the outer edge i of the window member e.
The space l surrounded by the space L becomes a kind of puddle, and the water stagnant here seeps into the vehicle interior along the edge g, despite the presence of the seal member h.
そのため前記特願昭59−104083号明細書及び図
面に記載されたルーフパネルにおいては、第４図
に示すように端縁部ｇの全周にわたつて連続突起
ｍを形成しており、この連続突起ｍが一種の堰と
なつて、前記シール部材ｈを通り越して侵入して
きた雨水が連続突起ｍの根元部分m′に溜まるよ
うに構成されている。 Therefore, in the roof panel described in the specification and drawings of Japanese Patent Application No. 59-104083, a continuous protrusion m is formed over the entire circumference of the edge g, as shown in FIG. The protrusion m functions as a kind of dam, and rainwater that has entered through the seal member h is configured to collect at the root portion m' of the continuous protrusion m.
「従来技術の問題点」

入するという不都合が存在する。"Problems with the Prior Art" As mentioned above, in this prior art, although the continuous protrusion m succeeds in temporarily damming up rainwater that has penetrated past the sealing member, in reality, In this way, the root part of the continuous protrusion m
The rainwater accumulated in m' cannot easily flow out to the left and right of the car, especially on the flat part of roof panel b, so the water accumulated in this root part m' may be affected by vibrations of the car, etc. There is an inconvenience that the liquid overflows and invades the vehicle interior as shown by arrow n.
また第４図に示したような従来例では、前記し

る場合があつた。 In addition, in the conventional example shown in Fig. 4, the reinforcing iron plate k is attached to the edge g by spot welding as described above, but the person operating the spot welding equipment does not attach the reinforcing steel plate k to the roof panel b during work. This is to operate the position of the spot welding electrode from the outside, and in particular, for the outside welding point p, the welding is performed while appropriately guessing the position of the end of the reinforcing iron plate k on the back side. This sometimes causes inconveniences such as spot welding at the wrong position, in which case the entire roof panel b may be defective.

In an automobile roof panel having a window member fixed by welding to open and close the opening, a first continuous protrusion is formed around the entire edge of the opening, and a first continuous protrusion is formed on the outside of the first continuous protrusion. This is a point where a second continuous protrusion is formed along the welding point in the left-right direction of the vehicle body when the reinforcing steel plate is spot-welded to the back surface of the edge of the opening, and the second continuous protrusion is formed at the second continuous protrusion. As a result, the function of preventing rainwater from entering the vehicle interior is further enhanced, and spot welding is performed along these continuous protrusions to prevent welding errors from occurring.

なお第３図及び第４図に示した構成要素と共通の
要素には同一の符号を使用して説明する。``Example'' Next, an example embodying the present invention will be described with reference to FIGS. 1 and 2 to provide an understanding of the present invention. Here, FIG. 1 is a perspective view showing the entire opening in a roof panel according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line A-A in FIG. 1.
Note that the same reference numerals are used to describe the same elements as those shown in FIGS. 3 and 4.
この実施例において、第３図及び第４図に示し

起１が形成されている点である。前記連続突起ｍ
が第１の連続突起であるのに対し、上記連続突起
１が第２の連続突起に該当する。 In this embodiment, the difference from the conventional roof panel shown in FIGS. 3 and 4 is that the welding points p are located on the outside of the continuous projection m with the opening c as the center, and are distributed in the left-right direction of the vehicle body. A continuous protrusion 1 is formed along this point. The continuous protrusion m
is the first continuous protrusion, whereas the continuous protrusion 1 corresponds to the second continuous protrusion.
このような連続突起１は、第１図に示す如く前
記開口ｃの端縁部ｇの内、特に車体の左右方向に
向かう辺の部分に設けることが防水性の点のみか
ら言うと望ましい。しかも、そのような連続突起
１は、ルーフパネルの平坦な部分に設けると特に
都合が良く、傾斜した部分に設けても防水性の点
から言えば、あまり意味がない。 From the standpoint of waterproofness, it is desirable to provide such a continuous protrusion 1 on the edge g of the opening c, particularly on the side facing in the left-right direction of the vehicle body, as shown in FIG. Furthermore, it is particularly convenient to provide such a continuous protrusion 1 on a flat portion of the roof panel, and even if it is provided on an inclined portion, it does not make much sense from the point of view of waterproofness.
上記のような連続突起１を設けた場合、第２図
において、シール部材ｈと端縁部ｇとの押しつけ
面から滲み出した雨水は、まず連続突起１の根元

かである。 When the continuous protrusion 1 as described above is provided, as shown in FIG. 2, rainwater seeping out from the pressing surface of the sealing member h and the end edge g first collects at the root portion 2 of the continuous protrusion 1. The amount of rainwater flowing into the root portion m' of the continuous protrusion m is extremely small. Since the continuous protrusion 1 as described above is mainly formed on the flat part of the roof panel b as described above, a certain amount of rainwater accumulates at the root part 2 of the continuous protrusion 1, and most of it is caused by vibrations of the vehicle body etc. As a result, it flows out in the left and right direction of the vehicle body along the continuous protrusion 1 as shown by the arrow 3, but due to sudden vibrations of the car, a part of it flows over the continuous protrusion 1 and flows in the direction of the continuous protrusion m, and flows to the root of the continuous protrusion m. It will temporarily accumulate in part m', but the amount is extremely small.
一方ルーフパネルの平坦部であつても車体の前

め、前記第２図に示したような連続突起１の存在
が非常に重要となる。 On the other hand, even if the roof panel is flat, at the edge g' (Fig. 1) along the longitudinal direction of the vehicle body,
Since acceleration due to the acceleration and deceleration of the car acts in the direction of the continuous protrusion m, the water that has accumulated in this part is quickly flowed forward or backward, and eventually rainwater is deposited on the edge part along the left and right direction of the car body. Therefore, the presence of continuous protrusions 1 as shown in FIG. 2 is very important.

共に溶接ミスが減少する。 In addition, when spot welding the reinforcing iron plate k to the lower surface of the edge g as described above, the continuous protrusion 1 is formed along the welding point p, so that the continuous protrusion 1 can be visually inspected. The position of the welding point p can be determined accurately, improving the efficiency of welding work and reducing welding errors.
