Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hood-type sunroof device having a foldable hood.

(Prior art) Similar to the panel type sunroof device, a canopy type sunroof device also uses a wind deflector to prevent wind from blowing into the room and to ventilate the room when the ceiling opening is opened. It is required to have the following.

A conventional wind deflector is disclosed in German Patent No. 1022481.

In this conventional device, the deflector plate is pivotally supported on the indoor side of the ceiling roof so that it can freely rotate about a horizontal axis, and when the top is opened, the deflector plate is rotated upward and projected upward from the ceiling opening. It is composed of

In the conventional device, the deflector plate is rotated manually and is separate from the opening/closing operation of the canopy, and the deflector plate protrudes from the inside to the outside of the ceiling roof, so a large-area plate is required to make the deflector plate protrude by the required amount. Not only is it necessary, but it also becomes an unnecessary item in the room when not in use.

Therefore, in order to solve the problems of the conventional device, it is possible to apply a wind deflector used in a panel type sunroof device.

For example, Utility Model Application Publication No. 56-59413 (shown in Figure 7)
In the technique disclosed in , a deflector plate 95 is pivoted around a horizontal axis in a rain gutter part F in front of an opening 2,
A guide member 96 is provided protruding from the deflector plate 95, and the guide member 96 is configured to be pressed against a stopper 98 by a spring 97, so that the deflector plate 95 is raised to the operating position. When the panel 99 that operates to open and close moves forward and rotates the guiding member 96 against the spring 97,
This allows the deflector plate 95 to be placed in a stored position.

(Problem to be solved by the invention) By the way, in the case of a hood-type sunroof device, if the front cover provided at the front end of the hood moves back and forth on the horizontal line, a wind deflector similar to the panel-type sunroof device should be used. However, since the hood is folded when opening the opening, it is located above the ceiling around the opening, and the front cover also moves back and forth on the upper side, and when closing, it moves from horizontal to forward downward. In the closed state, the panel type wind deflector is configured to ensure watertightness between the top and front cover and the ceiling roof, and it is difficult to use the panel type wind deflector as it is.

(Means for Solving the Problems) The present invention solves these various problems by pivoting the deflector plate 77 on the upper surface of the ceiling roof 1 in front of the opening 2, and by attaching the deflector plate 77 to the roof 22.
This problem is solved by providing a guiding member 80 which is rotated so as to come into contact with the upper surface of the front cover 23 as the front cover 23 moves downward.

That is, the specific configuration of the problem solving means of the present invention is as follows:
a flexible canopy 22 for opening and closing an opening 2 formed in the ceiling roof 1; a drive mechanism 51 for moving back and forth a front cover 23 provided at the front end of the canopy 22 and located above the ceiling roof 1; A guide mechanism 41 that guides the movement of the front cover 23 and guides it in the forward downward direction when the top is closed; and a wind deflector that is disposed in front of the opening 2 and is activated by the front cover 23 moving back and forth. The wind deflector mechanism 76 includes a deflector plate 77 rotatably supported via a horizontal shaft 78 located on the upper surface of the ceiling roof 1 and in front of the front edge of the opening 2. Then, when the front cover 23 moves backward, the upper surface of the ceiling roof 1 and the deflector plate 77 are arranged to raise the deflector plate 77 to the operating position A.
The rising means 86 provided between the deflector plate 77 and the front cover 23 extending rearward and upward from the vicinity of the horizontal axis 78 at the rear and lower side of the deflector plate 77 in the operating position A engages with the front cover 23 and moves forward and downward. It is characterized in that it has a guide member 80 that attaches the deflector plate 77 to the upper surface of the front cover 23 against the means 86 to bring it into the storage position (B).

(Function) When the front cover 23 is moved backward to open the opening 2, the deflector plate 77
When the front cover 23 is moved forward to close the opening 2, the front cover 23 moves forward and downward at the end of closing, and at that time engages with the guide member 80. This is pushed down against the rising means 86, whereby the deflector plate 77 also descends from the working position A and comes into contact with the upper surface of the front cover 23, achieving watertightness between the front cover 23 and the ceiling roof 1. At the same time, the deflector plate 77
A storage posture of 2 is obtained. The deflector plate 77 is located on the upper surface of the ceiling roof 1 even in this storage position B, and covers the front of the canopy 22 to block the wind.
2. Prevents flapping.

The guide member 80 is welded (or may be integrally molded) to the lower surface of the deflector plate 77, and is formed partially over the entire width of the deflector plate 77, only on both sides, or only in the center, and has an upwardly protruding portion. The deflector plate 77 is shaped like an arc.
A gap 87 with the deflector plate 77 gradually widens from the front end connected to the free end to the rear end of the free end.

When the deflector plate 77 is in the operating position A, the guiding member 80 is positioned so that the forward downward movement of the front end of the front cover 23 intersects with the midway portion thereof. As the deflector plate 77 is engaged and pressed down, the deflector plate 77 also rotates against the spring 85 of the rising means 86 so that its rear end descends. When the deflector plate 77 is in the storage position B, the front part of the front cover 23 enters deep into the gap 87, and the deflector plate 77 is attached to the upper surface of the front cover 23.

The canopy 22 and the front cover 23 are located on the upper side of the ceiling roof 1, and therefore the deflector plate 77 is also provided on the upper surface of the ceiling roof 1. Since the front cover 23 moves forward and downward when the opening is closed, the horizontal axis 78 is Opening 2
The guiding member 80 is positioned forward of the front edge of the deflector plate 77 and the horizontal axis 78
It extends backward and upward from the vicinity.

FIG. 6 shows another embodiment of the wind deflector mechanism 76', in which the upper front frame 6 serves as a support base, and a deflector plate 77 is mounted on the upper surface of the frame via a bearing portion 83 and a horizontal shaft 78. Pivotally supported, guiding member 8
0 and the upper front frame 6 is provided with rising means 86'.

The rising means 86' has one end of the leaf spring 88 screwed to the upper front frame 6, the other end of which is raised rearward and upward, and a long hole 89 is formed along the longitudinal direction in the middle of the spring. Pin 9 provided on guiding member 80
0 is engaged, the deflector plate 77 is raised by the repulsive force of the leaf spring 88, and the upper limit of the rise is set by the contact between the end of the elongated hole 89 and the pin 90, and the elongated hole 89 and the pin 90 are engaged. The relative movement of the deflector plate 77 allows the deflector plate 77 to descend.

Next, the operation of the device 3 according to the embodiment having the above configuration will be explained.

The front cover 23, shown by the solid line in FIGS. 1 and 2, is in the airtight position A in which the deflector plate 77 is attached from the front above the upper front frame 6 at the frontmost position and completely watertight. The canopy 22 is tensioned to ensure watertightness with the left and right upper frames 5. In this state, the movable body 35 is located at the front end of the cam groove 33 and pushes down the front part of the cam body 30, and the roller 28 hits the stopper 39 and enters the notch 38.

When the cable drive mechanism 51 is activated from this state to move the movable body 35 backward via the cable 36, the movable body 35 operates the forward raising mechanism 37, and the movable body 35 is relatively moved into the cam groove 33. Then, the cam body 30 is rotated so as to raise its front part without moving. As a result, the roller 28 separates from the notch 38, the support body 24 rotates around the pivot 25, and the front cover 23 assumes the forward upward tilting position B as shown in the imaginary line, and is separated from the ceiling roof 1 and the upper frame 4. Leave upwards. Note that the rear end 23a of the front cover 23 is located forward of the pivot 25 when in the closed position A so that the entire front cover 23 is separated from the upper frame 4. As the front cover 23 rises, the front cover 2
3, the deflector plate 77 which had been pushed down via the guide member 80 also rises as shown by the imaginary line in FIG. 1, making it possible to exert a wind-shielding effect.

In this way, when the front cover 23 is detached from the upper frame 4, the movable body 35 is at the rear end of the cam groove 33, and when it moves further rearward, it moves together with the cam body 30, and the support body 24 The roller 28 at the lower front end moves rearward as if guided by the auxiliary rail 15. Since the front cover 23 moves with the front upward tilted posture B, there is no sliding contact with the upper frame 5.

Moving the moving body 35 further backward, the front cover 2
3 is moved to approximately the middle of the opening 2, the top is at its final stage of opening, and the front lowering portion 40 acts during the backward movement. That is, the guide rail 10 is the auxiliary rail 1
5, and the gap H increases, so that only the guide shoe 26 rises from the forward upward tilting position B, and the support body 24 rises around the pivot 25.
Therefore, the front cover 23 assumes the forward downward position C. However, the front end of the front cover 23 comes into contact with the upper frame 5 and does not fall below that level.

When closing the top 22, the movable body 35 moves forward while pressing down the cam body 30, and the front end of the front cover 23 engages with the upper surface of the guiding member 80 before and after the roller 28 comes into contact with the stopper 39 and stops. It enters into the gap 87 with the deflector plate 77 while aligning. At this time, the guide member 80 may begin to be pushed down. Thereafter, the movable body 35 reversely operates the front ascending mechanism 37 to relatively move forward within the cam groove 33 to move the cam body 3
0 is pressed down, the roller 28 enters the notch 38, and the front cover 23 is pressed toward the upper front frame 6 side. Since the front end of the front cover 23 moves forward and downward while drawing an arcuate trajectory, it enters deep into the gap 87 while pushing down the guide member 80, and the deflector plate 77 is closely attached to the upper surface of the front cover 23.

(Effect of the invention) According to the invention described in detail above, the horizontal axis 78 of the deflector plate 77 is disposed on the upper surface of the ceiling roof 1 and in front of the front edge of the opening 2, and when the guiding member 80 is in the operating position. The deflector plate 77 extends rearwardly and upwardly from the vicinity of the horizontal axis 78, so that the hood 2
2 and the front cover 23 are a canopy type sunroof located above the ceiling roof 1, the guide member 80
By the posture and the front cover 23 moving in the forward downward direction, the deflector plate 77 can be changed from the operating posture A to the storage posture B, and when the deflector plate 77 is in the storage posture B, the deflector plate 77 can be moved to the upper surface of the front cover 23. In addition, the deflector plate 77 can not only effectively prevent wind from blowing in and ventilate the room when in the operating position A, but also prevent the ceiling roof 1 from leaking even in the storage position B. Since it is located on the top surface, it covers the front of the canopy 22, which also protrudes from the top surface of the ceiling roof 1, and prevents wind disturbance and prevents the canopy 22 from loosening or flapping due to the wind. can do.
