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 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 l-glass. A structure in which a roof panel is spanned is known. (Refer to British Patent Publication No. 2086316) In this structure, the roll bar can rotate around its both leg ends from an upright position to a tilted position stored in the passenger compartment behind the seat. Generally, a hood is stretched between the roll bar and the rear part of the vehicle compartment. 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 remove the roof of the car body and make it an open type, first remove the roof panel and store it in a designated storage location, and then move the roll bar to the tilted position. This required a two-step procedure in which the robot had to be brought down, and the removal work could not be carried out quickly. This also applies to the installation work of the vehicle roof.

The present invention has been made to solve these problems, and its purpose is to improve the operability of such attachment and removal operations.

(Means for Solving the Problems) To solve this problem, the present invention provides a roll bar which 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. , an open-top type automobile comprising a roof panel that can be spanned between the top of the roll bar and the top of the windshield to form a car body roof, the roll bar and the rear part of the car body of the roof panel; are connected via a hinge mechanism, and a storage section for the roll bar and loop panel is formed on the rear side of the vehicle body of the roll bar, and the front part of the vehicle body of the roof panel is connected to the front side of the roof panel. It is characterized in that it is rotatable at least between a first position where it can span over the top of the glass to form a vehicle roof, and a second position where the roll bar and roof panel can be stored in the storage section. That is.

(Effects of the Invention) In the present invention configured as described above, since the top of the roll bar and the roof panel are connected via the hinge mechanism, after the front end of the roof panel is removed from the upper end of the windshield, When the roll bar is tilted toward the rear of the vehicle, the roof panel moves as the roll bar rotates, and the roll bar and roof panel are folded around the hinge mechanism and stored in the storage compartment behind the seat. Therefore, unlike the conventional case where the roof panel must be completely separated from the roll bar for storage, the vehicle roof can be removed in a short time with simple operations. Moreover, the installation work is also easier than in the past.

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

FIGS. 1A, 18, and IC diagrams are perspective views showing one embodiment of the present invention, and FIGS. 2Δ, 3, and 4 are the ■-■ line, ■-■ line, and (2) It is a sectional view taken along the -TV line.

In the figure, ■ is a roll bar that has an inverted U-shape as a whole, and the tips 2 a s 3 a of both legs 2.3 of the roll bar are as follows:
It is rotatably attached to the inside of the automobile fender 4. This mounting position is at the rear side of the vehicle body of the side door 5. A roof panel 6 extends between the top 7 of the roll bar 1 and a front ladder 9 forming the upper end of the windshield 8. The roof panel 6 and the roll bar 1 are connected to a hinge mechanism 2 as described later.
Connected via 0. Next, 11 is a rear hood, which is stretched between the roll bar 1 and the chassis 12. A fastener 13 extending in the vehicle width direction is attached to the hood 11 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 separated from a portion 11a on the roll bar 1 side and a portion on the rear side of the vehicle body. It can be separated into 11b and 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 bar 1, roof panel 6, and rear hood II can be stored in this storage section 15. That is, the roll bar 1 is rotatable between an upright position (top position) as shown in FIG. 1A and a tilted position (open state) as shown in FIG. 1C. To store the vehicle, first, as shown in FIG. 1B, the fasteners 13 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, the front end of the roof panel 6 is removed from the front saddle 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 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. 1C, when the roll par 1 falls down almost horizontally and is in the tilted position stored in the storage section 15, 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 mechanism Next, referring to FIGS. 5 to 8B, the 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 a structure 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 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 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 on the rear end side 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.
A slide pin 205 protrudes from a sliding groove 205b formed in 05a and extending in the vertical direction of the vehicle body. Panel 205a
As shown in Fig. 7B, there is a slide pin 20 on the back side of the
A guide groove 205c of No. 5 is formed parallel to the sliding groove 205b, and a rectangular guide plate 205d that slides along the guide groove 205C is formed on the slide pin 205.
The amount of protrusion of the slide pin 205 from the panel 205a is constant, and the bin 205 itself is prevented from rotating. Furthermore, a moving groove 205f for the base end 205e of the slide pin 205 is formed following this guide m 205 c, and a spring 205g is inserted into this moving groove 205f, as shown in FIG. With this 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 member 213 attached to 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 bent 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 8A.

This will be described with reference to Figure 8B. FIG. 8A shows the roll par 1 in the upright position. In this state, the slide pin 20 is inserted into the engagement groove 206 of the first link 202.
5 is engaged, rotation of the first link 202 about the first rotating shaft 201 is prevented. Also, the second
Since the 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 rotating shaft 203, and in the opposite direction (arrow 2).
16) is prevented as long as the front end of the roof panel 6 engages the rudder 9 toward the front. In this state, when the roof panel 6 is removed from the front header 9 and the roll bar 1 is pushed backward while pressing down on the vehicle body, the roof panel 6 is moved to the second rotating shaft 203.
Rotate in the direction of arrow 216 around . 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.
12, the receiver pushes down the member 213 in the direction of the arrow 217 while moving its sliding surface 214''- toward the slide pin 205 side. 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 about the second and second rotation axes 201 and 203, respectively, and the roof panel 6 is folded toward the roll bar 1.

As described above, in this example, until the roll par 1 and the roof panel 6 are connected via the hinge mechanism of the two-hinge quip and the roof panel 6 is rotated by a predetermined amount, the rotation axis is centered on the second rotation axis 203. It is configured to rotate with a small rotation radius via the second link 204, and then rotate with a large rotation radius via the first and second links 202, 204 around the first rotation axis 201. . Therefore, the roof panel 6 can be stored inside the rollper 1 in the folded state, as shown in FIG. 1C, without the rear end of the roof panel 6 contacting the seal member 300 and damaging (gnawing) the seal member 104. be able to. To be more specific, for example, as shown in FIG. 9, when a single type hinge mechanism 20'' is used, both ends 6a and 6b of the roof panel 6 overlap the surface 102 of the rollper 1 on the front side of the vehicle body. There is a fear. On the other hand, in the two-hinge type, the rotation radius of the end of the roof panel relative to the roll bar 1 can be greatly prevented, so that the roll bar front surface 102 and the roof panel 6 can be prevented from overlapping.
