2. Description of the Related Art A convertible vehicle in which a roof panel of a passenger car and a back panel having a rear window glass are folded in two and can be stored in a storage space behind them is known, for example, from Japanese Patent No. 2519353. However, some of the convertible vehicles have been put into practical use in which the luggage room is shared with the storage space such as the roof panel and the luggage compartment.

In this case, it is more convenient to open the luggage door frontward when storing the roof panel or the like, and to open the luggage door rearward when loading and unloading the luggage. Therefore, as described above, the luggage door is opened. In a vehicle that shares a room with a storage space such as a roof panel and a luggage compartment,
The luggage door has a double-opening structure that can be opened and closed by either the rear hinge front opening method or the front hinge rear opening method.

[0004]

In a convertible vehicle capable of opening both sides of the luggage door as described above, due to the peculiarity of the luggage door opening / closing mechanism or the restrictions on the vehicle body shaping, as shown in FIG. When the front hinge is opened by the rear opening method, a locus may be drawn such that the left and right corners of the front end of the luggage door enter the luggage room in a plan view. Then, when water droplets adhere to the luggage door surface during the opening operation of the luggage door, the water droplets travel down the luggage door and drop into the luggage room from the left and right corners of the front end that are sharpened. It is not preferable because it will wet the luggage and the interior of the interior.

The amount of entry of the left and right corners of the front end of the luggage door into the luggage room is determined by the amount of wraparound of the left and right corners of the front end of the luggage door to the side of the vehicle body, that is, the center and left and right corners of the front end of the luggage door. The larger the distance is, the more remarkable the tendency becomes.

The present invention has been made in view of the above problems, and when the luggage door is opened by the front hinge rear opening method, the left and right corners of the front end of the luggage door enter the luggage room. Even if such a locus is drawn, it is an object of the present invention to provide a structure that can prevent water droplets from dropping from the luggage door into the luggage room.

[0007]

According to a first aspect of the present invention, there is provided a luggage door at a front end portion of a luggage door which can be opened and closed by a front hinge rear opening method and at a position corresponding to the inside of the left and right corner portions. It is characterized by having a water receiving part for collecting water flowing down from the luggage door when the door is opened.

The invention described in claim 2 is the same as claim 1.
As a more concrete description of the above, a water receiver for collecting water flowing down from the luggage door at the time of opening the luggage door at a position corresponding to the front end of the luggage door and the inside of the left and right corners. It is equipped with a corner weather strip equipped with a part, and this water receiving part drains the water collected in the water receiving part to the outside of the luggage room due to the inclination of the water receiving part itself when the luggage door is closed. It is characterized by that.

Further, according to a third aspect of the present invention, as a more specific form of the second aspect, the corner weather strip has a drip groove which functions as a water receiving portion. The lowest part of the luggage door in the closed state is open to the outside of the luggage room, and the lowest part of the luggage door has a draining lip projecting downward so that it points downward when the luggage door is closed. It has a feature.

Therefore, in the invention described in claims 1 and 2, for example, when the luggage door is opened by the front hinge rear opening method without knowing that water droplets are attached to the surface, the front end of the luggage door is temporarily Even if you draw a locus where the left and right corners enter the luggage room, the water that is transmitted from the left and right corners of the front end of the luggage door will be collected by the water receiver and will drip into the luggage room. There is nothing to do.

Particularly, as described in claim 2, a corner weather strip having a water receiving portion is attached to a front end portion of the luggage door and a position corresponding to the inside of the left and right corner portions. If the water receiving part has a predetermined slope, the water collected in the water receiving part will be naturally drained out of the luggage room due to the slope of the water receiving part itself when the luggage door is closed. Will be.

At the same time, as described in claim 3, when the draining lip at the lowest position among the drip grooves functioning as the water receiving portion is formed, the water in the drip groove is transmitted through the draining lip. It will flow or drip outside the luggage room, and the drainage performance from the drip groove will be further improved due to its draining effect.

[0013]

According to the invention as set forth in claim 1, even when the left and right corners of the front end of the luggage door are drawn into the luggage room when the luggage door is opened, the front end of the luggage door is drawn. The water that flows down from the left and right corners of the vehicle will be reliably collected by the water receiver, so there is no chance that the water will drip into the luggage room or it will wet your luggage or interior. Disappear.

In particular, according to the second aspect of the invention, since the water receiving portion has a predetermined slope in the closed state of the luggage door, the water collected in the water receiving portion closes the luggage door. At the same time, there is an advantage that it can be surely discharged to the outside of the luggage room promptly.

According to the third aspect of the present invention, since the draining lip projects from the lowest portion of the drip groove that will function as the water receiving portion, the drip groove is provided for its draining effect. It has the advantage of further improving the drainage performance.

And a luggage room 6 which can be opened and closed. The roof panel 2 and the back panel 4 are so-called hard panels, which are made of steel plates or the like, and are connected by a hinge (not shown) so that they can be folded (folded in two).

Then, as shown in the figure, when the fool panel 2 and the back panel 4 are in the deployed and used state, the roof panel 2 is butted against the front roof rail 7 on the side of the front window glass, while being electrically controlled, for example. Roof panel 2 and back panel 4
When the vehicle is folded and stored, the luggage door 5 first opens by the front opening method as shown in FIG. 7B, and then the back panel 4 rotates a hinge (not shown) while the roof panel 2 moves rearward in parallel. Both the panels 2 and 4 are tilted rearward about the center, and finally, the roof panel 2 and the back panel 4 are folded in two and the back panel 4 is in a substantially inverted posture with respect to the unfolded posture. It is stored in the luggage room 6. With this, the vehicle body 1 becomes a so-called open car.

Since the luggage room 6 is shared by the luggage space and the storage space such as the back panel 4, the luggage door 5 serves as a rear hinge when the back panel 4 is stored. While it can be opened by the front opening method, as shown in FIG. 2, a so-called double-opening type that can be opened by the front hinge rear opening method when loading and unloading luggage is adopted.

FIG. 3 is a perspective view of the right rear side of the vehicle body 1 of FIGS. 1 and 2 as seen obliquely from above, and FIG. 4 is a sectional view taken along the line AA of FIG. 3, that is, a lower edge portion of the back panel 4. Cross-sectional views are respectively shown, and a luggage weather strip 8A or 8B is attached to the opening edge of the luggage room 6 in a closed loop shape all around the opening edge. That is, the luggage weather strip 8A on the front side is provided at a portion (a portion along the lower edge of the back panel 4) corresponding to the front side of the luggage room opening edge in a plan view, and the other portions (left and right sides of the luggage room opening edge). And rear luggage weather strips 8B are mounted on the rear side) (see FIGS. 8, 10, and 11), and the end portions of the two are portions corresponding to the corner portion 20 of the luggage door 5. Are close to each other. These luggage weather strips 8
Since A and 8B are formed by forming the hollow seal lip 10 integrally with the welt portion 9 having a substantially U-shaped cross section,
When the luggage door 5 is closed, the inner lip 5a of the luggage door 5 is elastically contacted with the seal lip 10 for sealing.

An outer weather strip 11 is joined and fixed by a double-sided tape 12 to a portion of the front luggage weather strip 8A corresponding to the front side of the luggage room 6 as shown in FIG. The outer weather strip 11 has a substantially flat base portion 1.
3 has a hollow seal lip 14 formed integrally therewith, and when the luggage door 5 is closed, the front edge of the luggage door 5 elastically contacts the seal lip 14 and, as a result, a double seal structure by the seal lips 10 and 14. The inside and outside of the luggage room 6 will be sealed at.

Then, the outer weather strip 1 described above.
A drain groove 16 is formed by the base portion 13 of 1 and the flange portion 15 at the end thereof, and rainwater or the like intrudes into the inside from the seal portion due to the elastic contact between the front edge of the luggage door 5 and the seal lip 14 by any chance. In some cases, the water is collected in the drainage groove 16.

The luggage weather strip 8A and the outer weather strip 11 on the front side are gradually reduced in cross-sectional shape at both longitudinal ends thereof while both seal lips 10 and 14 gradually disappear as shown in FIG. The drainage grooves 16 are converged by the terminal type molding portion 17 having the seal lips 17a and 17b. Therefore, the drainage groove 16 is formed in the drip channel 34 on the side of the quarter panel (rear fender panel) 33 formed at the upper ends of both sides of the luggage room 6. It is open.

FIG. 5 shows the details of the portion B in FIG. 3, and as shown in the same figure, it is located at the front end of the luggage door 5 and at the position corresponding to the inside of the sharp left and right corners 20. A modified dish-shaped corner weather strip 21 is mounted on the. This corner weather strip 21
8 to 10 in addition to FIGS. 6 and 7, the inner panel 5 forming the corner portion 20 of the luggage door 5 is shown.
In addition to the panel receiving concave portion 22 that receives a, the first drip groove 23 that has a downward slope from the vehicle width direction central portion side to both ends in the vehicle width direction in the closed state of the luggage door 5, and this first drip groove 23. The first drip groove 23 is formed so as to be continuous with the first drip groove 23 at a position corresponding to the tip of the corner portion 20 of the luggage door 5, and has a depth larger than that of the first drip groove 23 and is rearward when the luggage door 5 is closed. The second drip groove 24 has a downward slope toward the side, and the second drip groove 24 also has an open passage 25 having a downward slope toward the rear side when the luggage door 5 is closed. It is opened to the outside, and finally converges with a sharpened draining lip 26 which is directed obliquely downward while forming the above-mentioned open passage 25. A void 27 is formed in a part of the corner weather strip to reduce its weight (see FIGS. 8 to 10).

As shown in FIGS. 5, 6 and 8, the panel receiving recess 22 of the corner weather strip 21 is provided with a truncated cone-shaped projection 28, and
A double-sided tape 29 is attached adjacent to it, and by fitting the protrusion 28 into the mounting hole 30 formed in the inner panel 5a on the side of the luggage door 5, the fitting holding force is increased. The corner weather strip 21 is fixed to the inside of the corner portion 20 of the luggage door 5 with the adhesive force of the double-sided tape 29.

The corner weather strip 21
8 to 10, a predetermined gap G is secured between the peripheral wall portion 31 forming the first and second drip grooves 23 and 24 and the front edge portion of the luggage door 5 as shown in FIGS. Therefore, at least the first and second drip grooves 23,
As will be described later, the reference numeral 24 will function as a water receiving portion for collecting water droplets flowing down from the luggage door 5 when the luggage door 5 is opened by the rear opening method.

Of the luggage weather strip 8A and the outer weather strip 11 shown in FIG. 4, a portion corresponding to the corner portion 20 of the luggage door 5, that is, a portion corresponding to the corner weather strip 21 is shown in FIG.
As described above with reference to FIGS. 10 to 10, both seal lips 10 and 14 are converged by the terminal mold forming portion 17 having the seal lips 17a and 17b, and the terminal mold forming portion 17 is the rear luggage weather. Strip 8
Since it is close to the end portion of B, when the luggage door 5 is closed as shown in FIG.
7a, 17b and the luggage weather strips 8A on both sides for the first time only by elastically contacting the seal lips 32 at the ends of the luggage weather strips 8B on the rear side.
The seal lines of 8B are connected in a closed loop, and the inside and outside of the luggage room 6 are sealed with this. The luggage luggage strip 8B on the rear side has an end extension 32a continuous with the seal lip 32.

At the same time, the corner weather strip 21
The tip of the peripheral wall portion 31 forming the first and second drip grooves 23, 24 directly comes into pressure contact with the seal lip 17a or the quarter panel 33 on the terminal mold forming portion 17 side. In the closed state, the first and second drip grooves on the corner weather strip 21 side are formed so as to overlap with the drain groove 16 formed by the terminal type molding portion 17 on the luggage weather strip 8A and the outer weather strip 11 side. 23, 2
4 is formed.

As is apparent from FIGS. 8 and 10 in addition to FIG. 4, since the drip channel 18 formed with the back panel 4 is connected to the drip channel 34 formed with the quarter panel 33, the luggage door is shown. In the closed state of 5, the drainage groove 16 on the outer weather strip 11 side and the open passage 25 on the corner weather strip 21 side are both in communication with the drip channel 34.

Therefore, according to such a structure, attention is paid to the sealing or drainage performance at the front edge of the luggage door 5 in the closed state of the luggage door 5 as shown in FIGS. 1A and 3. In this case, in the general portion shown in FIG. 4, since the luggage door 5 is elastically contacted with the seal lip 10 of the luggage weather strip 8A and the seal lip 14 of the outer weather strip 11, the luggage door 5 is sealed with a so-called double seal structure. Intrusion of rainwater, car wash water, etc. flowing down from the back panel 4 side is prevented. Even if water invades from the seal portion to the inside, the water is collected by the drain groove 16 of the outer weather strip 11, and finally from the drain groove 16 to the quarter panel shown in FIG. It is drained to the drip channel 34 on the 33 side.

At the corner portion 20 of the luggage door 5, as shown in FIGS. 8 to 10, the first drip groove 23 and the second drip groove 23 of the corner weather strip 21 are provided.
Since a part of the drip groove 24 of the above is open upward, water flowing down from the back panel 4 and the like is collected by the first and second drip grooves 23, 24,
From the open passage 25 communicating with them, the water is drained to the drip channel 34 on the side of the quarter panel 33 shown in FIG. 8 similarly to the above.

On the other hand, when the luggage door 5 is opened by the rear opening method as shown in FIG. 2 from the closed state of the luggage door 5 shown in FIG. 3, the luggage door 5 is pushed up in the direction of arrow a in FIGS. Since it is rotated while being rotated, the general portion (the central portion in the vehicle width direction) of the front edge portion of the luggage door 5 comes to be located right above the rear window glass 3, while the luggage door 5 Front edge corner 2
0 moves to the rear and is located above the luggage room 6 as shown in FIG.

When water drops are attached to the luggage door 5, the water flowing down from the general portion of the front edge of the luggage door 5 flows down the rear window glass 3 and the back panel 4, and then, as shown in FIG. It is temporarily stopped by the seal lip 14 of the outer weather strip 11 shown in the figure, further flows in the left-right direction while passing through the seal lip 14, and is drained to the drip channel 34 at the portion where the seal lip 14 disappears. If some of the water flowing down the back panel 4 gets over the seal lip 14 shown in FIG. 4, the water is collected in the drainage groove 16 and finally the quarter panel shown in FIG. 33
It is drained to the side drip channel 34.

The corner portion 20 at the front edge of the luggage door 5 is moved rearward as shown in FIG. 2 and FIG. 11, that is, the corner portion 20 is separated from the drip channel 34 on the quarter panel 33 side so as to be separated from the luggage room. 6
Therefore, when the corner weather strip 21 is not attached, the water drops flowing from the corner portion 20 at the front edge of the luggage door 5 cannot reach the drip channel 34 on the back panel side. Then, it will fall into the luggage room 6.

Therefore, in the present embodiment, as a countermeasure against this, the corner weather strip 21 is preliminarily attached as described above, and even if the luggage door 5 is set to the maximum opening state, the second depth is particularly large. Since the drip groove 24 is set to function as a water receiving portion,
As shown in FIG. 11, most of the water droplets flowing down from the corner portion 20 of the front edge of the luggage door 5 are formed in the first drip groove 23.
While flowing down or directly flowing down into the second drip groove 24, and is temporarily collected in the second drip groove 24. As a result, the front edge corner portion 2 of the luggage door 5
It is possible to prevent water droplets from falling from 0 to the luggage room 6 side.

Then, when the luggage door 5 is closed again, the corner weather strip 21 returns to the state shown in FIG. 10 while retaining the water W in the second drip groove 24. In this case, as described above, in the closed state of the luggage door 5, the second drip groove 24 has a downward slope toward the rear, and the drip on the side of the quarter panel 33 shown in FIG. Since it is opened to the channel 34, the water W held in the second drip groove 24 until then immediately propagates through the water draining lip 26, and then the drip channel 34
Will be drained to.

Here, since the trajectory in the direction opposite to the arrow a direction shown in FIGS. 8 to 10 is drawn in the process of closing the luggage door 5 in the closed state, the hollow seal lip 1 shown in FIG.
4 and the peripheral wall portion 31 shown in FIGS. 8 to 10 is not caught, and the state shown in FIGS.
