Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vehicle equipped with a folding top that can be opened and closed above the passenger compartment, and particularly relates to a room mirror provided in the front of the passenger compartment of the vehicle. It is something.

(Prior art) In vehicles such as automobiles, a rearview mirror is provided at the top of the front of the vehicle interior as a rearview mirror for viewing directly behind the vehicle. The mirror ensures rear visibility through the rear window. For this reason, such rearview mirrors are attached to a support base fixed to the vehicle body via a pole joint, and the angle can be adjusted vertically and horizontally. It is usually not possible to adjust it.

Similar rear-view mirrors are also provided in vehicles such as cabriolet cars that are equipped with a folding top that can be opened and closed above the passenger compartment. When the rear-view mirror is in use, that is, when it is in the cabin-closed position covering the upper part of the cabin, the rear view mirror provides rearward visibility through the rear window attached to the top, similar to a vehicle with a normal fixed roof. It is now guaranteed.

(Problems to be Solved by the Invention) In a cabriolet vehicle, when the top is not used, that is, when the passenger compartment is opened, the top is folded and stored on the rear upper surface of the vehicle body. In this case, since the folded top has a considerable volume, its height is considerably higher than the lower edge of the rear window when the top is in use. For this reason, if the rearview mirror has a constant vertical position, rear visibility will be obstructed.

If you install the rearview mirror at a higher position, you can secure rearward visibility when the top is stowed, but doing so will prevent you from seeing far behind through the rear window when the top is in use. Not only will this not be possible, but there is also a risk of interference with the hood being opened and closed.

For this reason, it may be possible to adjust the vertical position of the rearview mirror by, for example, fixing a vertical stay to the vehicle body and moving the rearview mirror up and down along this stay. In such cases, it is necessary to adjust and fix the rearview mirror up and down each time the top is opened or closed, which not only complicates the work of opening the passenger compartment or covering it with the top, but also makes it difficult for the rearview mirror to be in the raised position. At times, the stay extending downward becomes an eyesore.

The present invention was made in view of these problems, and its main purpose is to prevent the top from being folded and stored on the rear upper surface of the vehicle body even when the top is in the passenger compartment closed position covering the upper part of the passenger compartment. To ensure rear visibility through a rearview mirror even when the vehicle is in an open position.

Another object of the present invention is to automatically set the rearview mirror to a position suitable for the situation by simply opening and closing the top.

(Means for solving problems) To achieve this objective, in the present invention.

The rearview mirror is supported on the upper part of the vehicle body at the front of the cabin so that it can be raised and lowered, and an interlocking mechanism is provided that raises and lowers the rearview mirror in conjunction with opening and closing of the top. The rearview mirror is raised to a predetermined height when the top is opened, and lowered to a predetermined position when the top is closed.

(Function) With this configuration, when the top is opened and stored on the rear upper surface of the vehicle body, the room mirror rises, so that the rear view is not obstructed by the stored top.

Also, when the top is closed, the rearview mirror is lowered,
The height is suitable for obtaining rear visibility through the rear window.

(Example) Embodiments of the present invention will be described below based on the drawings.

1 to 4 show an embodiment of the elevating type rear-view mirror device according to the present invention, FIG. 1 is a schematic side view of a cabriolet car equipped with the elevating type rear-view mirror device, and FIG. It is a perspective view of the room mirror interlocking mechanism in the room mirror device. Moreover, FIGS. 3 and 4 are side sectional views for explaining the operation of the room mirror device.

As shown in FIG. 1, the cabriolet car 1 is equipped with a folding top 2, and the top 2 is in the position shown in phantom lines in the figure, that is, in the single-chamber closed position covering the upper part of the passenger compartment 3. It is designed to be opened and closed between the position indicated by the solid line in the figure and the cabin opening position where it is folded and stored on the rear upper surface of the vehicle body. A room mirror 6 is attached to the upper part of the vehicle body in front of the vehicle interior 3, that is, to the vehicle body portion 5 that supports the upper edge of the front window 4, so as to be able to rise and fall between a lowered position shown by a phantom line in the figure and a raised position shown by a solid line in the figure. It is being The lowered position is determined so that when the room mirror 6 is in that position, rearward visibility is ensured through the rear window 7 attached to the rear surface of the top 2. Further, the raised position is determined so that when the rearview mirror 6 is in that position, rearward visibility is secured above the folded and stowed hood 2.

The rearview mirror 6 is moved up and down in conjunction with the opening and closing operations of the top 2. The interlocking mechanism 8 is constructed as shown in FIG. That is, a hollow box-shaped mirror base 9 is fixed to the vehicle body portion 5 that supports the upper edge of the front window 4, and a stay 11 is vertically movable in a guide hole 10.10 provided on the upper and lower surfaces of the mirror base 9. It is inserted and passed through. A room mirror 6 is pivotally supported at the lower end of this stay 11 by a ballge indium 12 so that its angle can be adjusted vertically and horizontally. On the other hand, a spring receiver 13 is fixed to a portion of the stay 11 located inside the mirror base 9.
A compression spring 15 is installed between the mirror base 9 and a spring seat 14 on the lower surface of the mirror base 9.

Next, the operation of the elevating room mirror device configured as described above will be explained with reference to FIG. 3.4.

FIG. 3 shows a state in which the top 2 is closed. At this time, the upper end of the stay 11 is in contact with the front end of the top 2 and is pushed down against the elastic force of the spring 15. Therefore, the rearview mirror 6 is set in the lowered position. From this state, when you lift up to open hood 2, the 4th
As shown in the figure, since the pressing force of the hood 2 acting on the upper end of the stay 11 disappears, the spring receiver 13 of the stay 11 rises to a position where it comes into contact with the inside of the upper surface of the mirror base 9 due to the elastic force of the spring 15. However, the rearview mirror 6 is set to the raised position.

Figure 5.6 shows another embodiment of the present invention.
The figure is a longitudinal sectional view thereof, and FIG. 6 is an exploded perspective view of the interlocking mechanism. In the following description, the same reference numerals are given to the same components as in the embodiment shown in FIGS. 1 to 4 described above.

The interlocking mechanism 8 of this embodiment includes a stay 11 supported vertically movably on a mirror base 9 fixed to the vehicle body part 5;
It consists of a hook 17 pivotally supported by a hook base 16 fixed to the lower surface of the front end of the hood 2.

An upper limit groove 18 and a lower limit groove 19 are carved in the lower and upper parts of the front side of the middle part of the stay 11, respectively, and a leaf spring is pivotally supported in a recess 20 formed inside the mirror base 9 by a pin 21. 22 engages with these grooves 18 and 19, so that the stay 11 is set in the raised position or the lowered position. Further, below the upper limit groove 18 of the stay 11, there is a dust 2 for preventing removal, which is in contact with the lower surface of the mirror base 9 and restricts the upward movement of the stay 11.
3 is formed. Furthermore, at the top of the stay 11,
A pin 24 is provided to protrude left and right as a receiver for engaging the hook 17 and raising the stay 11.

On the other hand, a hook base 16 is attached to the lower surface of the front end of the canopy 2 with screws, and a seat surface 25 is formed in the center of the hook base 16, on which the upper end of the stay 11 comes into contact. A bracket 26 for pivotally supporting the hook 17 is protruded from the rear thereof. The upper part of the hook 17 is bifurcated and is rotatably supported by both ends of a shaft 28 which is inserted into a hole 27 of a bracket 26 and fixed thereto. The hook 17 is urged to rotate forward with respect to the shaft 28 by a spring 29. Furthermore, at the top of this hook 17.

A stepped portion 31 for restricting the forward rotation of the hook 17 by coming into contact with a stopper 30' formed on the hook base 16.
is formed. The lower part of the flap 17 is also formed into a bifurcated shape so that the receivers on both the left and right sides of the stay 11 can be engaged with the pin 24, and the engaging portions are formed in a bifurcated shape with respect to the axial direction of the stay 11. It is formed as a forward protruding part consisting of a downwardly inclined surface 32 forming an acute angle and an upwardly inclined surface 33 forming a nearly right angle.

Next, the operation of this embodiment will be explained.

When the top 2 is in the cabin opening position, the upper limit groove 18 of the stay 11 engages with a leaf spring 22 mounted in the mirror base 9, and the rearview mirror 6 is set in the raised position.

When the top 2 is closed from this state, the upper end of the stay 16 contacts the seat 25 of the hook base 16 and is pushed down.
When the lower limit groove 19 engages with the leaf spring 22, the room mirror 6 is set to the lowered position. During this time,
The hook 17 rotates backward when its downwardly inclined surface 32 contacts the pin 24 of the hook receiver of the stay 11, and then rotates forward due to the elastic force of the spring 29, and its upper inclined surface 33 However, the hook receiver engages with the pin 24-.

The engagement force between the upper inclined surface 33 of the hook 17 and the pin 24 is set to be stronger than the engagement force between the lower limit groove 19 and the leaf spring 22, so when the top 2 is lifted upward to fold it, the stay 11 is pulled upward together with the hood 2.

When the rearview mirror 6 reaches the raised position, the upper limit groove 18 engages with the plate spring 22, and at the same time, the stay 11 is pulled out by the prevention seat 23.
comes into contact with the lower surface of the mirror base 9. For this reason, the further rise of the stay 11 is restricted, so the hook 17
rotates backward, and the upper inclined surface 33 and the hook receiver are connected to the pin 24.
The hood 2 is then folded backwards, leaving the stay 11 in the raised position.

(Effects of the Invention) As is clear from the above description, the present invention provides a vehicle equipped with a folding top.

The rearview mirror is supported on the upper part of the vehicle body at the front of the passenger compartment so that it can be raised and lowered, and it can be positioned at a raised position at a predetermined height and a lowered position, so that the hood can be folded and stored on the upper surface of the rear part of the vehicle body. When the cabin is in the open position, by raising the rearview mirror, you can secure a rearward view that is not obstructed by the hood, and when the hood is in the cabin closed position, which covers the upper part of the cabin, By lowering the mirror, proper rear visibility through the rear window can be obtained. In addition, the rearview mirror is automatically raised and lowered in conjunction with the opening and closing of the top, which not only saves you the trouble of raising and lowering it, but also reduces the risk of forgetting to change the position of the rearview mirror. Nor.

Furthermore, since the rearview mirror in the raised position is lowered when the top is closed, there is no interference between the top and the rearview mirror.
