Description

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

(Prior Art) As the upper structure of this type of automobile, a roll bar having an approximately inverted U shape is spanned between both side walls of the vehicle body, and a removable roll bar is installed between the top of the roll bar and the top of the Freon 1 glass. A structure in which a roof panel is spanned is known (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 canopy is generally placed between the two. When the roll bar is placed in the upright position, the area behind 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. .

(Problem to be Solved by the Invention) In such a structure, in order to tilt the roll bar so as to store it in the passenger compartment behind the seat, the maximum length of the roll bar in the vehicle width direction must fit 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, if the outside side of the roll bar leg is formed vertically, since both side walls of the car body are thick, the outside side of the car body and the roll bar leg are formed vertically. There will be a difference in level between the sides. In order to eliminate this level difference, it is possible to form a protrusion on the outer side of the roll bar leg to cover 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 (belt line), when the roll bar is tilted, the protrusion will interfere with the upper ends of the vehicle body side walls, making it impossible to tilt the roll bar into the storage space behind the seat. It is something that will disappear.

The present invention has been made to solve these problems, and its purpose is to allow the roll bar to be stored in the passenger compartment behind the seats without interfering with the side walls of the vehicle body. In this case, the object 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 further, a surface of the roll bar on the outside of the vehicle body located above the first protrusion in the first position is formed on both legs of the roll bar. It is characterized in that a second protrusion is formed that protrudes outward from the vehicle body so as to form a slope that is substantially continuous with the outer surface.

(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 eliminates interference between the roll bar and the side walls of the vehicle body, making it possible to store the roll bar in the passenger compartment behind the seats. Additionally, it becomes possible to smoothly connect the outer side of the roll bar to the outer side of both side walls of the car body with a continuous slope, improving the appearance of the car body.

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

2A, 2B, and 2C are perspective views showing one embodiment of the present invention, and FIGS. 1A, 3, and 4 are the 1-II line, ■-■ line, and FIG. 3 is a sectional view taken along line IV-■.

In the figure, reference numeral 1 denotes a rollper having an inverted U-shape as a whole, and the tips 2a and 3a of its legs 2.3 are
．． It is rotatably installed inside the fender 4 of the IJ vehicle. This mounting position is the rear part of the vehicle body of the side door 5 (the part where it is located).
It spans between the top 7 of the roll bar 1 and a front I header 9 that constitutes one end of the windshield 8.

The car roof panel 6 and the roll bar 1 are connected via a hinge mechanism 20, as will be described later. Next, 11
is the rear hood, which is stretched between the roll bar 1 and the chassis 12. This hood 11 has a fastener 1 extending in the vehicle width direction at a position near the rear side of the vehicle body relative to the roll bar 1.
3 is attached, and with this fastener 13, the top 11 can be separated into a portion 11a on the rollper 1 side and a portion Ilb on the rear side of the vehicle body. 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 bar 1, roof panel 6, and rear hood 11 can be stored in this storage section 15. That is, the roll bar 1 is rotatable between an upright position (covered state) as shown in FIG. 2A and a tilted position (open state) as shown in FIG. 2C. When storing, first,
As shown in Figure B, the fasteners 13 are removed to separate the rear hood 11, and the rear section 11b is stored in the storage section I5 located below the vehicle body (top state). Next, the front end of the roof panel 6 is removed from the front header 9, and the roll bar 1 is tilted toward the rear of the vehicle body. In this rotational movement, since the roof panel 6 is connected to the roll bar 1 via the hinge mechanism 20, it moves toward the rear of the vehicle body as the roll bar 1 rotates. Therefore, as shown in FIG. 2C, the roll bar 1 falls down almost horizontally, and the storage section 15
When the roll bar 1 and the roof panel 6 are in the tilted position, the roll bar 1 and the roof panel 6 can be stored in a folded state between the legs.

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

Hinge mechanism Next, referring to FIGS. 5M to 8B, the roll bar 1
The hinge mechanism that connects the roof panel and the roof panel 6 will be explained.

The roll bar 1 and the roof panel 6 are connected via hinge mechanisms 20 and 20 at two locations on the left and right, and the hinge mechanism 20 connecting the leg portions 3 of the roll bar 1 and the roof panel 6 is shown in the figure. It's a common thing. As shown in the figure, the hinge mechanism includes a first
It is of a two-hinge type having a link 202 and a second link 204 rotatable around a second rotation axis 203.

An engagement groove 206 for a slide pin 205 attached to the rollper 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 shaft 203 at its center. The end face 209 of the second link 204 is latched by a latching portion 210 formed at the tip of the first link 202, so that the second link 204 can only rotate in the direction of the arrow 211 about the second rotation axis 203. It is possible. The lower end 212 of the second link 204 is held by a member 213 that is attached to the slide pin 205, and the tip 214 is fixed to the side of the roof panel 6 at the rear end of the vehicle body. Also,
A protrusion 215 is formed on the second link 204 to release the engagement 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 pin assembly has its front panel 205a attached to the inner panel 101 of the rollper 1, and its front panel 205a attached to the inner panel 101 of the rollper 1.
Vehicle body drilled at 05a - sliding groove 205b extending downward
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 slide groove 205b, and the slide pin 205 has this guide groove 205C.
A rectangular guide plate 205d is formed to slide along the slide pin 205, so that the amount of protrusion of the slide pin 205 from the panel 205a is constant, and the bin 205 itself is prevented from rotating. Also, this guide? *205c is followed by a moving groove 205f for the base end 205e of the slide pin 205. As shown in FIG. 6, a spring 205g is inserted into this moving groove 205f.
The slide pin 205 is always biased toward one side of the vehicle body. Further, the protruding direction of the slide pin 205 is set to be approximately horizontal. Next, the receiver member 213 attached to the tip of the slide pin 205 will be explained. This member 213 has a substantially trapezoidal shape, its lower bottom side is fixed to the slide pin 205, and is inclined downward toward the front of the vehicle body toward the bottom side. Further, both side surfaces are bent upward, and the sliding surface 2 of the lower end 212 of the second link 204
14 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. Further, 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 around the second rotating wheel 203, and in the opposite direction (arrow 216
) is prevented as long as the front end of the roof panel 60 engages the rudder 9 toward the front. In this state, when the roof panel 6 is removed from the front header 9 and the rollper 1 is pushed backward while pushing the vehicle body downward, the roof panel 6 is moved to the second rotating shaft 20320.
3 in the direction of arrow 216. That is, the second
The link 204 rotates in the direction of arrow 216 around the second rotation axis 203, and this rotation causes the end 2 of the second link 204 to rotate.
The bearing 12 moves on the sliding surface 214 toward the slide pin 205 while pushing down the member 213 in the direction of the arrow 217. As a result, the slide pin 205 to which the receiver member 213 is attached moves in the sliding groove 205b against the spring force of the spring 205g.

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 around the second and second rotating wheels 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. It is configured to rotate at a small rotation radius via two links 204, and then rotate at a large rotation radius about the first rotation axis 201 via the first and second links 202 and 204. . Therefore, the second C.
As shown in the figure, the rollper 1
The roof panel 6 can be stored inside. Specifically, as shown in FIG. 9, for example, when a single type hinge mechanism 20' is used, both ends 6a and 6b of the roof panel 6 are connected to the front surface 10 of the rollper 1 on the vehicle body front side.
There is a possibility that it overlaps with 2. On the other hand, in the two-hinge type, the rotation radius of the end of the roof panel with respect to the roll bar 1 can be increased, so that overlap between the roll bar front surface 102 and the roof panel 6 can be avoided.

Attaching the Roller Next, the rollper 1 and its mounting portion will be explained with reference to FIGS. 1A to 1F.

As described above, the roll par 1 has a substantially inverted U-shape, and is pivoted to the inside of the rear fender 4 at the tips 2a and 3a of both legs 2.3.

[Structure between roll bar and chaffender] As shown in FIG. 1A, the legs 3 of the roll bar 1 are rotatably attached to the inside of the inner panel 4b via pins 48. The reinforcing members 49 and 50 constitute a mounting portion for this pin 48. The overall shape of the reinforcing member 49 is as shown in FIG.
It is blocked by a. On the other hand, in the lower half, a side wall 49b on the inner side of the vehicle body and a front wall 49C on the front side of the vehicle body in the upper half are inclined toward the inside of the vehicle body and the front side of the vehicle body to form an inclined wall 49d. A flange 49e for attaching an inner panel is formed on the outer edge of the reinforcing member 49, and a flange 49f for attaching a floor panel is formed at the lower end of the inclined wall 49d. Reinforcement member 4
9 is attached to the vehicle body by joining these flanges 4.9e and 49f to the inner panel 4b and the lower lower panel 51, respectively. On the other hand, the reinforcing member 50 has a U-shaped cross section that opens outward from the vehicle body, and extends in the vertical direction of the vehicle body. The outer ends of the front and rear walls of the reinforcing member 50 facing the longitudinal direction of the vehicle are bent in the longitudinal direction of the vehicle to form flanges, which are joined to the side wall 49C of the reinforcing member 49. ing. Further, a flange 50f bent toward the inside of the vehicle body is formed at the lower end of the side wall 50e of the reinforcing member 50, and is joined to the inclined wall 49d of the reinforcing member 49.

Here, the distance between the side walls 49c and 508 of both reinforcing members 49, 50 is set to a width that allows the roll bar leg 3 to be inserted. In addition, pin insertion holes 49h, 5' are provided in these side walls 49C150e and the tip of the roll bar leg 3.

Rear Top Next, a structure for attaching the rear top to the vehicle body will be described with reference to FIGS. 3, 4, and 10. As described above, the rear hood 11 is divided into two parts, the front and rear parts of the vehicle body, by the fasteners 13. First, of these two halves, the rear side of the car body is section 11.
The structure for attaching the U to the vehicle body in b will be explained. At the attachment portion of the hood 11b, the hood cloth is double-layered, and the outer hood cloth on the outside surface of the vehicle body can be removed from the vehicle body using a clasp such as a hook. However, the inner hood cloth on the inside of the vehicle is fixed to the vehicle body and cannot be removed. That is, as shown in FIG. 4, the portion facing the side wall of the vehicle body indicated by diagonal lines in FIG. 10 is doubled by the outer hood cloth 11c and the inner hood cloth lid. The end portion lie is fixed to the upper end portion of the rear fender 4 via a seal member 11f. The end portion 11g of the outer hood cloth 11C is removably fixed to the end portion lie of the inner hood cloth with a clasp such as a hook. On the other hand, the ends of these hood cloths 11C111d on the upper side of the vehicle body are joined to each other, and the hood cloths 11C and 111d on the upper side of the vehicle body
It is connected to 1h. Here, the inner hood cloth lid has a folded portion 111 on its upper end side, and the folded end 11j of the inner hood cloth 11d stretched from the vehicle body is
It is pulled up toward the hood cloth 11h by the elastic member 11k. In this way, the inner hood cloth lid has a folded portion 11i.
Therefore, when the hood 11b is stored in the storage section 15, the hood cloth 1], d can be brought into close contact with the storage section partition plate 151''. In other words, in order to change from the top state shown by the solid line in the figure to the top state shown by the two-dot chain line, first,
It is sufficient to open the fastener 13 to separate the top 11b from the top 11a, and then remove the end 11g of the outer top cloth 11c from the vehicle body. At this time, since the end portion 11e of the inner hood lid remains fixed to the vehicle body, it is impossible to store the inner hood lid in close contact with the side and bottom surfaces of the accommodating portion 15 due to the dimensions of the inner hood lid. In this example, for this purpose, the inner hood cloth lid
A folding portion 11i is provided in the holder so that its length can be increased when stored. Therefore, in this example, l1llb can be stored in close contact with the side and bottom surfaces of the storage section 15, as shown by the two-dot chain line.

Next, the portion of the hood inclined toward the rear of the vehicle body, indicated by B in FIG. 10, will be explained. The attachment end of this part to the vehicle body is connected from the hood cloth 11h to the inner hood cloth 11 as shown in FIG.
d and the outer hood cloth 11c are branched, and the inner hood cloth li
The end portion d is fixed to the vehicle body via a seal member 11f and cannot be removed. A member 11fi having an angular cross section and having one end fixed to the mounting portion is disposed on the rear side of the vehicle body of the mounting portion. The heel portion 11m of this member 11β faces upward of the vehicle body, and the outer hood cloth 1
The ends 1] and 1g of 1c are removably attached with clasps such as hooks. The two-dot chain line in the figure shows the state of the top 11b when it is stored. Incidentally, rainwater that enters from the outside through the end 11g of the outer register 11c flows through the corner formed by the inner hood cloth end 11f and the member 11β, and is discharged from the side of the vehicle body. .
