(Prior Art) For example, as a hood type sunroof device for a passenger car, devices shown in FIGS. 5 to 7 have been proposed in the past.

That is, in FIGS. 5 to 7, 1 is a hood type sunroof device, which is arranged to open and close an opening 3 formed in a ceiling roof 2 of a passenger car or the like.

A receiving part 4 is formed at the peripheral edge of the opening 3 of the ceiling roof 2 by press working and is integrally bent downward and inward, and the sunroof device 1 is supported on this receiving part 4.

The receiving portion 4 also serves as a rain gutter, and a seaming welt 5 is provided on its inner peripheral edge, and an indoor opening 6 is formed inside the seaming welt 5. 7 is an interior board.

A support stand 8 is fixed to the left and right receiving parts 4, and a guide rail 9 is supported on each support stand 8.

Reference numeral 10 denotes a flexible canopy that covers the opening 3 in an openable and closable manner, and its front end is attached to the front cover 11. This front cover 11 is attached to a sliding body 12, and this sliding body 12 has a mounting base 13 that supports the front cover 11, support arms 14 attached to the left and right sides of the mounting base 13, and a lower end of the support arm 14. The guide shoe 15 is slidably guided by the guide rail 9.

The rear end of the hood 10 is attached to the rear cover 16,
After this, the cover 16 is attached to the mounting plate 17 fixed to the bottom surface.
is attached to the receiving part 4 on the rear end side of the opening part 3. Further, a sealing material such as a weather strip is appropriately attached to the lower surface of the outer periphery of the hood 10.

Reference numeral 19 denotes a flexible lining cloth, the front end of which is attached to the mounting base 13 through a plate material, and the rear end thereof to the mounting plate 17. A roof 21 is formed.

Inside this bag-shaped roof 21, there are horizontal beams 22 for supporting the canopy 10 from below and assisting in tensioning and folding.
A plurality of floating aggregates 23 are provided alternately. The horizontal aggregate 22 is a pipe or a round bar with both ends flattened to form a hanging part 24, and supporting arms 25 are attached to both ends of the hanging part 24.
A guide shoe 26 is provided through the guide shoe 26, and U-shaped hook pieces 27 are attached to both ends of the guide shoe 26. The hooking portions 24 are inserted into and hooked to both sides of the canopy 10,
The hook pieces 27 are hooked to both sides of the backing cloth 19, and the guide shoe 26 is allowed to slide within the guide rail 9. The floating aggregate 23 also has a hook part 28 and a hook piece 29 like the horizontal aggregate 22, and
and are hung on each side of the backing cloth 19 to provide tension in the lateral direction.

The mounting base 12 and the hanging piece 27 of the horizontal aggregate 22 include
Links 30 projecting rearward are pivotally supported to be vertically slidable, and a hooking piece 29 of the floating aggregate 23 is pivotally attached to the rear end of each link 30. And mounting base 1
A tension spring 31 is hung between the locking piece 3 or the link 30 and the link 30 so as to bias the floating aggregate 23 upward. Therefore, the floating aggregate 23 is
When it loosens in the front-back direction, it floats up from the upper surface of the ceiling roof 2, as shown for example by the imaginary line in FIG.
The folding is guided so that the hood 10 is folded into a wave shape.

A hanging part 32 formed into a cylinder by sewing both ends of the cloth is provided on the upper surface side of the backing cloth 19, and this hanging part 32 fits into the horizontal aggregate 22 and the floating aggregate 23. Then, the backing cloth 19 is formed using the horizontal aggregate 22 and the floating aggregate 23.
The hood 10 is configured to suspend the hood 10.
When folded, the lining fabric 19 will also be folded in the same way.

A pin 33 protrudes inward from the support arm 14, and a notch in the vertical direction of the cable holder 34 engages with this pin 33. The cable holder 34 is slidably inserted into a cable guide 35 formed on the support base 8. One end of a drive cable 37 of the drive mechanism 36 is connected. Also, the gearbox 38 of the drive mechanism 36
is arranged on the lower surface of the front receiving part 4, and can push and pull the two cables 37 by rotating the handle 39 or the motor. The sliding body 12 can be driven and operated in the front and rear directions via the holder 33.

(Problem to be solved by the invention) In this type of hood type sunroof device 1, when the handle 39 is operated, the sliding body 12 slides rearward, and the horizontal aggregate 22 and floating aggregate 23 move rearward. At the same time, the floating aggregate 23 connects the link 30 and the spring 3
1, the top 10 is folded rearward as shown by the imaginary line in FIG. 6, and the opening 3 can be opened.

In this way, the floating aggregate 23 jumps upward due to the spring force of the spring 31, but due to the swaged state of the hinge pins at both ends of the link 30, the inclination of the link 30 at both ends with respect to the latching pieces 27, 29, and the Sufficient jumping force may not be obtained due to variations in force, etc. Therefore, if the floating aggregate is slid backward without being lifted up enough, as shown in Figure 8, the floating aggregate 2
The latching piece 29 of No. 3 interferes with the horizontal aggregate 22 on the rear side, making it impossible to fold the top 10.

Conversely, if the spring force of the spring 31 is large, the spring force will exceed the tension of the hood 10 when fully closed, and the floating aggregate 23 will float, so that the hooking piece 29 will
cannot be reliably pressed against the seaming welt 5, and a gap may occur between the lining fabric 19 and the seaming welt 5.

In view of these problems, the present invention was provided with the aim of making it possible to reliably fold the top 10 even when the spring force that urges the floating aggregate 23 upward is reduced. .

(Means for solving the problem) The present invention provides, as a means for solving the problem, a ceiling roof 2
Horizontal aggregates 22 and floating aggregates 23 that support the flexible canopy 10 that covers the opening 3 from below are provided alternately in the front and rear direction, and the horizontal aggregates 22 are arranged in pairs on the left and right sides of the opening 3. A spring 31 supports the floating aggregate 23 so as to be slidable back and forth along the guide rail 9, connects the floating aggregate 23 to the sliding side via a link 30 so as to be movable up and down, and urges the floating aggregate 23 upward. In the hood-type sunroof device provided with the floating aggregate 23 at both left and right ends of the flexible hood 10,
An elastic member 35 is installed in the front-rear direction between the link 30 supporting the structure and the horizontal aggregate 22 on the opposite side so as to assist the floating aggregate 23 to jump up during folding.

(Function) When the horizontal aggregate 22 moves rearward when the flexible canopy 10 is folded, the floating aggregate 23 supported via the link 30 is jumped up by the spring 31.
At this time, the elastic material 31 attached to the canopy 10 on the rear side of the floating aggregate 23 assists the floating aggregate 23 to jump up, so the floating aggregate 23 surely jumps up and interferes with the horizontal aggregate 31. It crosses over backwards without any trouble.

(Example) The present invention will be described in detail below with reference to the illustrated embodiment. Components with the same names as those in the conventional example shown in FIGS. 5 to 8 are given the same reference numerals, and their explanations will be omitted. As shown in Figures 1 and 2, a flexible canopy 1
Folded portions 10a are formed at both left and right ends of 0, and the hook portions 24 and 28 at both left and right ends of the horizontal aggregate 22 and floating aggregate 23 are attached to the folded portions 10a. It has been inserted. and,
In the folded portions 10a at both left and right ends of the canopy 10, floating aggregates 23 are connected via links 30 to the sliding body 12 or horizontal aggregates 22 on the opposite side.
An elastic member 35 is attached in the front-rear direction between the link 2 and the link 30, that is, in the portion where the link 30 is not provided. Although the front end of the elastic member 35 is bent into an arc shape, the rear end may be bent in the same manner. In addition, 3
6 and 37 are hinge pins.

In the above configuration, when folding the top 10 by sliding the sliding body 12 backward, the link 30, the hooking piece 2
9, the floating aggregate 23 is urged upward by the tension spring 31, so if the horizontal aggregate 22 side moves backward, the floating aggregate 23 also moves backward as shown in FIG. jump upwards. At this time, there is a hood 1 between the floating aggregate 23 and the horizontal aggregate 22 behind it.
0 tries to bend, but there is an elastic material 3 in this part.
5, so when the floating aggregate 23 moves backward, the elastic member 35 relatively pushes up the floating aggregate 23 on the front side while deforming the elastic member 35. Therefore, the floating aggregate 23 is the third
From the figure to the state shown in Figure 4, the rear horizontal aggregate 2
2, the hanging pieces 29 of the floating aggregate 23 and the horizontal aggregate 22 do not interfere with each other on the way.
The top 10 can be folded smoothly and reliably.

In addition, since the elastic material 35 assists the floating aggregate 23 to jump up, a tension spring 31 with a weak spring force can be used. Therefore, when fully closed, the floating aggregate 23
The lining fabric 19 is not lifted up by the hooking piece 29.
can be securely pressed against the seaming welt 5 to prevent the occurrence of gaps.

Note that the elastic material 35 is not limited to a band-like material, and a wire material may also be used.

(Effect of the invention) According to the invention, between the floating aggregate 23 and the horizontal aggregate 22 on the opposite side of the link 30 that supports the floating aggregate 23 at both left and right ends of the flexible canopy 10. In addition, since elastic members 35 are provided in the front and rear direction to assist the floating aggregate 23 to jump up during folding, the horizontal aggregate 22 due to insufficient jumping of the floating aggregate 23 as in the conventional case.
It is possible to prevent interference with Furthermore, since the elastic material 35 assists the floating aggregate 23 to jump up, the spring force of the spring 31 that urges the floating aggregate 23 upward can be reduced. Therefore, when fully closed, the lining cloth 1 is removed from the floating aggregate 23 side.
In the type in which the fabric 9 is pressed against the seaming welt 5, it is possible to prevent a gap from forming between the backing fabric 19 and the seaming welt 5.
