Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an upper body structure for an automobile, and more particularly to an upper body structure for an open-top automobile to which the roof of the vehicle body can be attached and removed.

(Prior Art) As for the two-part structure of this type of automobile, a roughly inverted U-shaped roll bar is spanned between both side walls of the vehicle body, and is removable between the top of the roll bar and the top of the windshield. It is known that a roof panel is placed over the roof panel (see British Patent Publication No. 2086316).

With this structure, the roll bar can rotate around its leg ends from an upright position to a tilted position where it is stored in the passenger compartment behind the seats. A general canopy is placed between the two. When the roll bar is placed in the upright position, the area behind the conductor from the roll bar is covered by a hood, and in this state, a roof panel can be placed between the roll bar and the windshield to form the roof of the vehicle body.

(Problem to be Solved by the Invention) In such a structure, in order to tilt the roll bar to be stored in the passenger compartment behind the seat, the maximum length of the roll bar in the vehicle width direction must be within the storage space behind the seat. It must be shorter than the length in the vehicle width direction. In that case,
When the roll bar is in the upright position, the roll bar 7111
If the outer side of the vehicle body is formed vertically, a step will be created between the outer side of the vehicle body and the outer side of the roll bar leg because both side walls of the vehicle body have a thickness. In order to eliminate this step, it is sufficient to form a protrusion that extends the outer side of the roll bar leg to a position that covers the upper ends of both side walls of the car body when it is in the upright position. If this protrusion is formed directly above the one end position (hell line), when the roll bar is tilted, the protrusion will interfere with the surface of the first end of the vehicle body side walls, and the storage area behind the seat will It becomes impossible to make a table topple over the space.

The present invention was made to solve these problems, and its purpose is to prevent the roll bar from interfering with the side walls of the vehicle body (and to allow it to be stored in the vehicle interior behind the seats). In addition, in this case, the objective is to improve the appearance of the vehicle body by preventing a difference in level between the outer side surface of the roll bar leg and the outer surface of both vehicle body walls when the roll bar is in the upright position.

[Means for Solving the Problems] To this end, the present invention provides a roll bar that has a substantially inverted U-shape and is spanned between both side walls of the vehicle body so as to be rotatable in the longitudinal direction of the vehicle body centering on both leg ends. and a roof panel that can be spanned between the top of the roll bar and the top of the windshield to form a vehicle roof. A storage section is formed, and the roll bar is arranged in a first position where the front part of the vehicle body of the roof panel can be spanned over the top of the windshield to form a vehicle roof; The roll bar is rotatable at least between a second position where the roll bar can be stored, and the upper ends of both side walls of the vehicle body facing the both legs of the roll bar in the first position are substantially continuous with the outer surfaces of the side walls of the vehicle body. The first with a slope of
A protrusion is formed on both legs of the roll bar, and a surface of the roll bar on the vehicle body outer side located above the first protrusion in the first position is formed on the vehicle body outer surface of the first protrusion. A second protrusion protrudes outward from the vehicle body so as to form a substantially continuous slope; is characterized in that a seal portion is formed to seal between the side window and the side window.

(Effects of the Invention) In the present invention configured as described above, a protruding portion having a slope that is substantially continuous with the outer surface of the both side walls of the vehicle body is formed at the upper end of both side walls of the vehicle body, and the projecting portion is protruded to a position above the protruding portion. Since a protruding part is formed on the outer side of the vehicle body of the roll bar, the lower end of the protruding part, which is the maximum length of the roll bar in the vehicle width direction, is closer to the inside of the vehicle interior. This makes it possible to store the rollper in the passenger compartment behind the seat, eliminating interference between the rollper and the side walls of the vehicle body. Additionally, it becomes possible to smoothly connect the outer side of the rollper to the outer side of both side walls of the car body with a continuous slope, improving the appearance of the car body.

Furthermore, in the present invention, a seal portion for sealing between the side window and the side window is formed on the front side of the vehicle body of the protruding portion formed at the upper end of the side walls of the vehicle body, so that the side window can be closed as much as possible. It becomes possible to arrange it toward the outside of the vehicle, and it becomes possible to achieve so-called flushing by reducing the level difference between the outer side surface of the rollper and the outer surfaces of both vehicle body walls and the side window surface.

(Example) Examples of the present invention will be described below with reference to the drawings.

2A, 2B, and 20 are perspective views showing one embodiment of the present invention, and FIGS. 1A, 3, and 4 are the ■-■ line, ■-■ line, and It is a sectional view along the TV-TV line.

In the figure, reference numeral 1 denotes a rollper having an inverted U-shape as a whole, and the tips 2a and 3a of both legs 2.3 of the rollper are rotatably attached to the inside of an automobile's rear fender 4. This position is a portion of the side door 5 on the rear side of the vehicle body. 6 is a roof panel, which spans between the top 7 of the roll par 1 and the front header 9 that constitutes the upper end of the windshield 8. This roof panel 6
and the roll par 1 are connected via a hinge mechanism 20, as will be described later. Next is the 11 bariya hood,
It is stretched between Roller 1 and Chahoday 12. This hood 11 is provided with a fastener 13 extending in the vehicle width direction at a position near the rear side of the vehicle body relative to the roll bar 1, and this fastener 13 allows the hood 11 to be connected to a portion 11a on the roll bar 1 side and the vehicle body. It can be separated into a rear portion 11b. Furthermore, a rear window 14 is attached to the center portion of the rear hood 11. Reference numeral 15 denotes a storage section provided in the vehicle interior below the rear hood 11, and the roll par 1, roof panel 6, and rear hood 11 can be stored in this storage section 15. That is, the roll par 1 is rotatable between an upright position (topped state) as shown in FIG. 2A and a tilted position (open state) as shown in FIG. 2C. To store the vehicle, first, as shown in FIG. 2B, the fasteners 3 are removed to separate the rear hood 11, and the rear portion 11b is stored in the storage section 15 located below the vehicle body (top state). Next, remove the front end of the roof panel 6 from the front soda plate 9 and tilt the rollper 1 toward the rear of the vehicle body. In this rotational movement, since the roof panel 6 is connected to the rollper 1 via the hinge mechanism 20, it moves toward the rear of the vehicle body as the rollper 1 rotates. Therefore, as shown in FIG. 2C, when the roll par 1 falls down almost horizontally and is in the tilted position stored in the storage part 5, the roof panel 6 is folded between its legs. The roll par 1 and roof panel 6 can be stored.

In FIGS. 3 and 4, the states of the roll par 1, roof panel 6, and top 11 when stored are shown by two-dot chain lines.

Hinge Next, with reference to Figures 5 to 8B, roll par 1
The hinge mechanism that connects the roof panel 6 and the roof panel 6 will be explained.

The roll par 1 and the roof panel 6 are connected through hinge mechanisms 20 and 20 at two places on the left and right, and the figure shows the hinge mechanism 20 that connects the legs 3 of the roll par 1 and the roof panel 6. be. As shown in the figure, the hinge mechanism includes a first
It is of a two-hinge type having a link 202 and a 21st J link 204 rotatable around a second rotating ring 203.

An engagement groove 206 for a slide pin 205 attached to the roll bar leg 3 is formed in the center of the first link 202 . The second rotating shaft 203 is attached to the tip of the first link 202, and the second link 204 is pivotally connected to the second rotating ring 203 at its center. The end face 209 of the second link 204 is fixed by a hook 210 formed at the tip of the first link 202.
This makes it possible to rotate only in the direction of arrow 211 about the second rotating shaft 203. Second link 204
The lower end 212 of the slide pin 205 is held by a member 213, and the tip 214 is fixed to the side of the roof panel 60 on the rear end side of the vehicle body. Furthermore, a protrusion 215 is formed on the second link 204 for releasing the engagement state between the first link 202 and the slide pin 205.

Next, the assembly of the slide pin 205 will be described in detail. As shown in FIGS. 6 to 7B, this bin assembly has a front panel 205a attached to the inner panel 101 of the rollper 1, and the front panel 205a of the rollper 1.
Sliding hole 4205b extending in the vertical direction of the vehicle body opened at 05a
A slide pin 205 protrudes from. Panel 205
On the back side of a, as shown in Fig. 7B, there is a slide pin 2.
05 guide groove 205c is formed parallel to the sliding pin 205b, and the slide pin 205 has this guide groove 205c.
A rectangular guide plate 205d is formed to slide along C, so that the amount of protrusion of the slide pin 205 from the panel 205a is constant, and the pin 205 itself is prevented from rotating. Further, a moving groove 205f for the base end 205e of the slide pin 205 is formed following the guide groove 205C, and a spring 205g is inserted into this moving groove 205f, as shown in FIG. Due to the spring,
The slide pin 205 is always urged toward the upper side of the vehicle body. Further, the protruding direction of the slide pin 205 is set to be approximately horizontal. Next, slide pin 2
The receiving member 213 that can be reached at the tip of 05 will be explained. This member 213 has a substantially trapezoidal shape, its lower base side is fixed to the slide pin 205, and its upper base side is inclined downward toward the front of the vehicle body. Further, both side surfaces are pressed upward, and the sliding surface 214 of the lower end 212 of the second link 204
is formed.

The operation of the hinge mechanism configured in this way is described in Section 88, 8B.
This will be explained with reference to the figure. FIG. 8A shows the roll par 1 in the upright position. In this state, since the slide pin 205 is engaged with the engagement groove 206 of the first link 202, the first
Rotation of link 202 is prevented. Furthermore, since the second link 204 is engaged with the protrusion 210 of the first link 202, it is prevented from rotating toward the rear of the vehicle body about the second rotation shaft 203, and in the opposite direction (arrow 216
) is prevented as long as the front end of the vehicle body of the roof panel 6 is engaged with the front header 9. In this state, when the roof panel 6 is removed from the front header 9 and the rollper 1 is pushed down toward the vehicle body while falling backward, the roof panel 6 rotates in the direction of arrow 216 around the second rotating wheel 203. That is, the second link 204 rotates in the direction of the arrow 216 about the second rotation shaft 203, and as a result of this rotation, the end 212 of the second link 204 pushes down the member 213 in the direction of the arrow 217, and the sliding surface of the second link 204 is rotated. 214 to the slide pin 205 side. As a result, the slide pin 205 to which the receiver member 213 is attached moves into the sliding groove 205 against the spring force of the spring 205g.
Move b.

Next, when the roof panel 6 rotates by a predetermined amount, the eighth B
As shown in the figure, the slide pin 205 is connected to the first link 20
2 to a position where it is removed from the engagement groove 206. In this state, the tip 21 of the protrusion 215 of the second link 204
Inner panel 10 8 forms the top 7 of the roll par 1
1. Therefore, when the roof panel 6 is further rotated from this state, the first link 202 is rotated by the second link 204 in the direction of arrow 219 about the first rotation axis 201 using the protrusion tip 218 as a fulcrum, and the engagement groove 20
Slide pin 205 is completely removed from inside 6. After this, the first and second links 202 and 204 rotate about the second and second rotation axes 201 and 203, respectively, and the roof panel 6 is folded toward the rollper 1 side.

As described above, in this example, until the roll par 1 and the roof panel 6 are connected via the two-hinge type hinge mechanism and the roof panel 6 rotates by a predetermined amount, the rotation axis is rotated about the second rotation axis 203. 21J link 204 with a small rotation radius, and then rotates around the first rotation axis 201 with a large rotation radius via the first and second links 202 and 204. . Therefore,
The rear end of the roof panel 6 contacts the sealing member 300,
without damaging the seal member 104.
As shown in Figure C, the roof panel 6 can be stored inside the roll bar 1 in the folded state. In detail, for example, as shown in FIG. 9, when a single type hinge mechanism 20'' is used, the roof panel 6
Both ends 6a and 6b are the front surface 1 of the roll par 1.
There is a possibility that it overlaps with 02. On the other hand, in the case of the two-hinge quip, the rotation radius of the end of the roof panel relative to the roll bar 1 can be set large, so that overlap between the roll bar front surface 102 and the roof panel 6 can be avoided.
