【発明の詳細な説明】 本発明は降雨時走行する車輛例えばバス車体等の各引窓
敷居材レール部から客室内に浸入する雨水の排水仕末の
構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for draining rainwater that enters a passenger compartment from each sliding window sill rail of a vehicle such as a bus body that runs during rain.

従来この種技術は、例えば引抜き軽合金成形材等を用い
て、内外側各二枚の引窓用敷居溝を一体構造に成形し、
これを用いて更に窓枠全体をも完成せしめ、この中に引
窓ガラスを嵌めたものを車体に装着するという手段が講
ぜられている。Conventionally, this type of technology involves molding two inner and outer sliding window sill grooves into an integral structure using, for example, a pultruded light alloy molded material.
This is then used to complete the entire window frame, which is then fitted with sliding glass and then mounted on the vehicle body.

しかし、この構造で車輛が雨天走行すると窓を閉鎖中で

衣その他を濡らすので、これの排水対策としてレール部
下面に複数の排水孔を設け、更に車体とこのレール部下
面との間に排水用間隙を設けてこの貯溜水を車体外に静
的に排出する構造手段が各種考案されている。However, when a vehicle with this structure is driven in the rain, even with the windows closed, rainwater collects on the rail of the sill groove and wets the passengers' clothes and other surfaces. To prevent this, multiple drainage holes are installed on the underside of the rail. Various structural means have been devised to statically discharge the accumulated water to the outside of the vehicle body by providing a drainage gap between the vehicle body and the lower surface of the rail.

併用せしめんとする構造等がそれである。For example, a system in which the drainage hole is provided on the side surface of the rising part of the rail,
If the base of the rail is cut out or holes are opened like this, dust from outside the car will fly into the cabin on sunny days, so we added a filter component to this to allow rainwater to pass through while also filtering dust. This includes the structure that

然しこれ等の手段では雨天高速走行とすると雨水が客室

枠に穿孔して雨水と外気の分離を試みたものもあるが、
これ等は敷居材上面の雨水仕末にはその機能を発揮しな
い等のことから乗客の不満をかい、末だ完全にその目的
を果す装置は創作されていない。However, with these methods, if you drive at high speed in the rain, rainwater will blow into the cabin along with the outside air and scatter, making complete drainage impossible, or the filters placed in these positions will become clogged. On the other hand, there are disadvantages such as impeding the static removal of accumulated water and reducing the function of the drainage hole.Some attempts have been made to separate rainwater and outside air by drilling holes in the side chamber frame, but
These devices have caused dissatisfaction among passengers because they do not perform their function in draining rainwater from the top surface of the sill material, and unfortunately no device has been created that completely fulfills that purpose.

ちなみに第１図は本発明が生れた基本的技術理念を示す
ものであるが、この種車輌が雨天走行して窓枠周囲わけ
ても敷居材上面から客室内に雨水が□浸入して来るのは
単に家屋用雨戸のそれの様に突風や、気象的異状現象に
よる吹き付けや、浸入とは全く異なる要因から発生する
。By the way, Figure 1 shows the basic technical idea behind the invention, but when this type of vehicle is driven in the rain, it is simply a matter of rain water entering the passenger compartment from the top surface of the sill material even if it is separated around the window frame. It occurs due to factors completely different from gusts of wind, blowing due to abnormal weather phenomena, and infiltration, such as those caused by storm shutters on houses.

即ち、そもそも高速走行中の車体周囲にはその空気力学
的吸出効果が発生し、車体前部周囲の隙間から室内空気
を吸出して車内気圧を車外圧に対して負圧化する現象が
発生する。That is, an aerodynamic suction effect occurs around the vehicle body while the vehicle is running at high speed, and interior air is sucked out from the gap around the front of the vehicle body, causing a phenomenon in which the pressure inside the vehicle becomes negative relative to the pressure outside the vehicle.

これに対し、もともとバス等の車体は雨もシ、塵埃の客
室）０浸入を彷止すＬだめに、その気密性を配慮して製
作されるが、雨天走行時はこれらの全部が閉鎖されるの
で残された隙間からの吸出効果が顕著に現われる。On the other hand, the bodies of buses and other vehicles are originally designed to be airtight to prevent rain and dust from entering the passenger compartments, but all of these are closed when driving in the rain. As a result, the suction effect from the remaining gaps is noticeable.

わけても車体前方に位置する運転手が運転席前面窓の雲
シを排除したい等の目的から、その側窓を若干でも開け
ると、その位置がこの吸出効果の発生に適しているので
速度と共に強大な車内客室空気量の排出となシ、結果、
この客室負圧現象を激増せしめて逆にその車体後方の客
室窓間隙部から外気の強力な吸い込み現象が発生する。In particular, when a driver located at the front of the vehicle opens the side window even slightly to remove clouds from the front window of the driver's seat, the position is suitable for this suction effect to occur, and the effect increases as speed increases. As a result, the amount of air in the cabin of the vehicle is discharged,
This phenomenon of negative pressure in the cabin increases dramatically, and conversely, a strong suction of outside air occurs from the gap between the cabin windows at the rear of the vehicle body.

When one or both of these are fenestrated, the airtight material 9 adhesively fitted into the fitting groove 8 of the lower sill material 4 into which they are slidably fitted prevents leakage of bonding with the glass surface. A hole 19 is formed on the contact surface between the front edge and the airtight material 9, and this moves with the sliding movement of the window glass, but water leakage from this hole is caused by the fitting of the lower sill material 4. A plurality of drainage holes 15, 15' are formed at the bottom of the groove 8.
The notch holes 18, 18'...
Since the water is discharged outside the car body through ..., there is no leakage into the car interior.

室内外に吸い込まれ、吹き込む様に作用する。Next, when this car body runs at high speed in the rain, the above-mentioned suction effect occurs mainly because a pressure difference is created between the inside of the car body cabin and the outside air, and the outside air is normally rapidly sucked in from each gap in the car body. The gaps near windows, on the outside, and on the other side are most susceptible to this effect, and especially from the notches 18, 18', etc., water is sucked into the room and outside as a droplet, and it acts as if it were blown into the room.

ます様に作動する。However, in the present invention, the airtight material 9, which is constantly adhesively fitted into the fitting groove 8, is in close contact with the four circumferences of the inner and outer window glass to exclude rainwater from these, so that unlike conventional methods, rainwater does not enter from these. No phenomenon was observed, especially on the inside window glass 10.
Rainwater reaching the bottom of the fitting groove 6 is sucked in from the direction of the arrow in the direction of the arrow d, which generates an air flow inside the L-shaped guiding separation material 13 adhesively fixed in front of it, and from the lower side of the When attempting to climb up the inner wall of the rising section with the airflow, in this case, it encounters upward resistance due to the shape of the inner wall of the rising section, and along with this, the accumulation of moisture that occurs here. Due to the increase in water droplets, the water droplets gradually become larger in size, increase in weight, fall, and are discharged to the outside of the vehicle through a drainage hole 15 of the necessary size provided below the lower side of this L-shaped induction separation material 13. As this is repeated, the intake air generated in the direction of the arrow d is not accompanied by any rainwater, and it can be completely separated, and it operates in such a way that only fresh outside air is sucked into the cabin.

いう全く新たな効果を生むことが出来た。Since the present invention operates as described above, rainwater and dust from various gaps in the vehicle body such as side windows are mixed in due to the above-mentioned suction effect that inevitably occurs when large vehicles are driven at high speeds. In order to prevent mixed air from entering, it is essential to have a vehicle body structure that can separate and remove these rainwater and dust.As is clear from the above-mentioned effects, in the present invention, the structure of the vehicle body that can separate and remove rainwater and dust is essential. The combined structure of the small hollow L-shaped conductor separator with the back that connects this and the lower drainage hole allows the separation of air and rain water and dust that is created by the rear rise, which cannot be seen with a structure that only has two legs. The action occurs automatically, and even when driving in rain, only this separated fresh air is introduced into the cabin through a large amount of hollow L-shaped induction separating material in response to the pressure difference generated by the suction effect. This produced a completely new effect: there was no small amount of suction into the passenger compartment from the various gaps in the car body, and it was possible to completely prevent rain water and dust from entering the cabin.

な効果のある発明となったものである。Moreover, this growth can be achieved even if the external shape is, for example, a half-moon shape, as long as there is resistance to the creeping up of the mixed air caused by the rear surface of the L-shaped induction separating member. As shown in Fig. 7, the inner wall of the L-shaped guiding separation material has a protruding strip, or as shown in Figure 7, the internal shape is deformed into a wave shape, or as shown in Figure 7, the upper end of the rising part. These methods, such as combining a mesh-like filtration part with a mesh filter part, have the effect of effectively filtering raindrops and dust contained therein depending on the strength of the intake air flow. The size of the window, the negative pressure difference generated by the vehicle speed, and the airflow are greatly related, so if you select and use windows with other shapes at the appropriate time, you can apply them to various vehicles and have similar effects. In addition, it has a simple structure and once installed, there is no need for conventional maintenance such as removing clogging during use, making it an extremely simple and highly effective invention. .
