DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure for a vehicle.

[0002]

2. Description of the Related Art Conventionally, in a simple small-sized vehicle such as a golf cart, a roof side rail is arranged on both sides in a width direction of a roof panel along a front-rear direction. A rain rail having a channel cross section is formed in a concave portion at these joints, so that rainwater that has fallen on the roof surface is drained to the front and rear of the vehicle along the rain rail.

[0003]

However, the conventional rain rail does not have a sufficient drainage amount, and when the rainfall is large, the rain rail overflows from the rain rail and rainwater dripping from the roof side occurs. I was To increase the drainage of the rain rail, simply increase the height of the wall provided on the outer edge of the roof side panel to prevent overflow, but high protrusions damage the design. This is not an effective measure. The present invention has been completed based on the above-described circumstances, and an object of the present invention is to provide a roof structure capable of reliably draining water without impairing the design of a vehicle.

[0004]

According to a first aspect of the present invention, there is provided a roof for a vehicle having a roof having recesses formed on both side edges in the width direction of the vehicle roof along the front-rear direction. A rainwater overflow prevention wall is formed upright on the outer edge of the rain rail,
An overflow auxiliary rail portion communicating with the rain rail is provided outside the overflow prevention wall in the width direction.

According to a second aspect of the present invention, there is provided the vehicle according to the first aspect, wherein the vehicle has an open / close entrance.
At the entrance, a curtain is provided so as to be openable and closable,
A curtain rail, which slidably fits the hanging member of the curtain, is formed integrally with the rain rail along the front-rear direction.

[0006] Further, the invention of claim 3 is claim 1 or 2.
The rain rail is connected to a side edge of a roof panel via a seal material, and a flange edge for positioning with respect to the seal material is provided on an edge of the rain rail opposite to the overflow prevention wall. Are formed upright.

[0007]

According to the first aspect of the present invention, the rainwater that has fallen on the roof is guided along the rain rail in the front-rear direction of the vehicle and drained. Also,
If rainwater that overflows from the rainrails flows in, it flows into the auxiliary rails from the rainrails and is drained from the auxiliary rails as well, so it does not flow down from the side edges of the roof as before. Can be avoided.
In addition, since the auxiliary rail portion is disposed outside in the width direction of the rain rail, the protrusion dimension of the rain rail is not increased, and therefore, a good appearance can be maintained.

<Invention of Claim 2> According to the invention of Claim 2, the rain rail is also provided with a curtain rail, so that the multi function of the rain rail can be achieved. <Invention of Claim 3> According to the invention of Claim 3, when the roof panel and the rain rail are joined, the sealing material can be positioned and set between the overflow prevention wall and the flange edge.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. <First Embodiment> A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the entirety of a small-sized simple vehicle 10 for one person. As shown in the figure, the entrances 25 set on the left and right sides of the driver's seat are fully open. The roof panel 17 of the vehicle 10 includes a rear pillar 12 erected at the rear of the vehicle 10, a pair of side rails 30 arranged on both sides in the width direction of the roof panel 17,
5 and 7, and is supported by the support members 24 on the plurality of roof members 23 shown in FIGS.

The entire roof panel 17 is formed so as to have a slight downward slope, and the front edge thereof is bent in a stepped shape along the width direction. Is glued. A bulge portion 18 as shown in FIG. 2 is formed in a central portion of the upper surface of the roof panel 17 so as to bulge out with a smooth curved surface.
The rainwater that has fallen on the roof panel 17 can be effectively guided to both sides. That is, the bulge portion 18 is formed such that the inclination in the width direction of the vehicle 10 is steeper than the inclination in the front-rear direction of the vehicle 10, as is apparent from the cross-sectional views of FIGS. This makes it easier for the rainwater that has fallen on the bulge portion 18 to be guided to the side rail 30 side. Further, in this embodiment, a rear dam 21 having a mountain-shaped cross section is provided so as to protrude from a rear end portion of the left and right side edges of the roof panel 17 to a rear edge portion thereof to restrict rainwater from flowing down from behind. I have. Furthermore, a front dam 19 is formed one step higher at a position along the upper edge of the front window 13 in front of the bulge portion 18 described above. The boundary edge of the rear part of the front dam 19 has a bilaterally symmetrical downward slope toward both ends in the width direction. At both ends of the front dam 19 in the width direction, a rain garter 20 shown in FIGS.
Is provided, and a downward slope is formed up to the upper surface of the roof panel 17 which is one step lower. For this reason, the rainwater that has fallen on the roof panel 17 does not flow down to the front window 13 as it is, but is once blocked by the front dam 19, guided to both sides, and collected by the rain garter 20 provided here. It flows down along the left and right sides of the window 13.

The both side rails 30 are made of extruded aluminum, and are integrally formed over the length range from the left and right sides of the front window 13 to the rear end of the roof panel 17. And
The left and right sides of the front window 13 serve as front pillars, and one end of the side rail 30 projects into the hood 11 and is joined to the vehicle body frame (not shown). Further, as shown in FIG. 7, the other end of the side rail 30 is continuous with being fitted inside the rear dam 21.

The cross section of the side rail 30 is as follows.
As shown in FIG.
This is a form having chambers (first to third chambers 31 to 33), and is functionally a rain rail part 34 for receiving rainwater flowing from the roof panel 17, and an auxiliary rail part 41 disposed outside the rain rail part 41 for overflow. And a curtain rail portion 50 for the curtain 15 covering the entrance 25 of the vehicle 10.

The rain rail portion 34 includes an installation surface 35 having a downward slope and an overflow prevention wall 42 which is continuous with the installation surface 35 and is substantially vertical. The installation surface 35 is for connection to the roof panel 17, and the roof panel 17 is formed with a stepped roof flange 22 on both side edges in the width direction, and a sealing material 38 is provided on the installation surface 35. Are overlaid. And
Pop nuts 36 at predetermined pitch intervals along the length direction,
It is fixed by tightening with bolts 39. In the present embodiment, a positioning protruding edge 40 is formed upright on the inner edge of the installation surface 35 along the length direction to prevent the sealing material 38 from shifting. When the side edges of the roof panel 17 in the width direction are joined to the side rails 30 in this manner, the surface formed by the roof flange 22 and the overflow prevention wall 42 becomes a rain gutter capable of draining rainwater.

The auxiliary rail portion 41 is provided continuously with respect to the overflow preventing wall 42 outward in the width direction.
2 are held. However, the end of the second chamber 32 on the side protruding into the hood 11 is open.

A plurality of drainage holes 43 are opened at predetermined intervals in the length direction at the center of the overflow prevention wall 42 in the height direction, and penetrate into the second chamber 32. For this reason, when the water level of the rainwater collected in the rain rail portion 34 rises to the opening position of the drain hole 43, the rain water is drained.
Then, it flows down to the second chamber 32, passes through the second chamber 32 as it is, and is drained from the end inside the hood 11.

Further, the third chamber 33 provided at a position sandwiched between the first chamber 31 and the second chamber 32 has a rail groove 51 formed on the lower surface thereof along the length direction. Is slidably accommodated.

Thus, according to the first embodiment of the present invention configured as described above, the bulge portion 18 provided on the roof panel 17 makes it easier for rainwater to flow to the side rails 30 than to the front and rear. . Therefore, the rainwater is collected in the rain rail portion 34 of the side rail 30, guided to the front side of the vehicle 10 along this, and drained from the end through the hood 11. When the amount of rainfall reaches a level at which the rainwater stored in the rain rail portion 34 reaches the drain holes 43, the rainwater immediately enters the second chamber 32 through the drain holes 43. Then, it flows down into the hood 11 in the same manner as above, and is drained from the end.
Therefore, even when the amount of rainfall is large, there is no possibility of getting over the overflow prevention wall 42. Thus, the rainwater is at the entrance 25
Therefore, the water is surely drained through both side rails 30 without flowing down.

Of the rainwater that has fallen on the roof panel 17, the one that has flowed forward is also the front dam 19.
It is blocked by the damper and is distributed to both sides, and flows down both sides of the front window 13 via the rain garter 20. Therefore, only a small amount of the rainwater that has fallen on the roof panel 17 flows down to the vicinity of the center of the front window 13, which is effective for securing a good front view, and the wiper 26 can be omitted. . The rear dam 21 provided at the rear of the roof panel 17 effectively prevents rainwater from flowing down from the rear of the vehicle 10.

In the present embodiment, the following effects are also obtained. That is, if the curtain 15 is attached via the curtain liner 16 in rainy weather, it is possible to avoid blowing rain from the entrance / exit 25, but the curtain rail portion 50 for attaching such a curtain 15 is provided with a side rail. Since it is provided integrally with the device 30, it can be manufactured at low cost without any trouble of mounting. In addition, the curtain rail portion 50 is a side rail 3
Since it is arranged inside the zero and does not protrude downward, it does not become an unnecessary protrusion and does not interfere with getting on and off.

Further, the installation surface 35 of the rain rail portion 34
Since the positioning ridge 40 is projected on the
Positioning is easy and the work is easy. Further, the sealing material 38 is hidden, and the appearance from the inside of the vehicle is improved.

Furthermore, in the prior art, the side rail 30 is divided into a portion corresponding to both side edges of the front window 13 and a portion corresponding to both side edges of the roof panel 17, and these are connected. In the present embodiment, the side rails 30 are integrally formed by using an extruded aluminum material. Therefore, the effect that the number of parts and the number of work steps can be reduced is also obtained.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. The difference from the first embodiment is the configuration of the rear part of the roof panel 17. In the second embodiment, the rear dam 21 is not provided on the roof panel 17 as in the first embodiment, and rear rails 30 having the same cross-sectional shape as those on both sides are separately attached to the rear end of the roof panel 17. It is connected to the rear end. Along with this, the roof flanges 22 are also arranged continuously from both sides at the rear end of the roof panel 17 and the side rails 3
0 can be attached. Other configurations are the same as those of the first embodiment.
The same reference numerals are given and the description of the structure, operation and effect is omitted.
