Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rear window support device for a cabriolet vehicle in which the roof and rear upper part of the vehicle body are covered with a foldable canopy.
The present invention relates to a support device for a rear window attached to a flexible top body.

(Prior Art) The roof frame of a cabriolet car is usually constructed of a link frame that is rotatably attached to the car body in the longitudinal direction, and a flexible hood body made of cloth or the like is placed on the link frame. It is designed to be installed. The hood body has a portion that forms the roof portion of the vehicle body, and a rear surface portion that connects the rear edge of the roof portion and the rear upper edge of the vehicle body,
A rear window is provided at the rear part. Further, the link frame is pivotally supported by the vehicle body in front of the part fixed to the vehicle body at the rear end of the top body, and the top body is fixed to the link frame at the front and rear edges of the roof part. There is.

In this way, in a cabriolet car, the hood is closed by rotating the link frame forward and unfolding the links, and the hood is opened by rotating the link frame backward and folding the links. It is like that. When the top is closed, the rear part of the top body is tensioned between the rear edge of the roof part and the part fixed to the vehicle body, and the rear window provided there is held in a predetermined position. ing. Also, when opening the canopy, the rear part of the canopy body bends appropriately in the middle.
The entire canopy can be folded compactly.

(Problem to be solved by the invention) However, when the rear window is supported by a flexible canopy body, weather conditions such as outside temperature and humidity, errors during assembly, errors in the product, etc. Alternatively, the hood body may stretch due to aging, and the rear window may fall forward from its set position due to its own weight. especially,
When the rear window is made of glass, the weight of the glass is large, and the weight of the glass frame and the like is added to the rear window, which causes the rear window to tilt more. If the inclination of the rear window becomes larger than a predetermined inclination as described above, it becomes impossible to obtain rearward visibility commensurate with the area of the rear window.

In addition, when glass is used for the rear window, the rear part of the top body must be folded at the upper or lower part of the rear window, so the pivot position of the roof frame to the vehicle body must be adjusted to the top body. It is necessary to place it far away from the part that is fixed to the vehicle body, making it difficult to install it in small vehicles. Therefore, it is conceivable to make the rear window part separable from the top main body, fold only the rear window part and store it, and then fold the top main body. However, in such a case, even when closing the top, it is necessary to further lift the rear window and attach it to a predetermined position after closing the top body, which takes time and effort.

Due to these problems, it has been considered to use a foldable transparent plate made of synthetic resin for the rear window, but such a transparent plate made of synthetic resin cannot be said to have good visibility or appearance.

The present invention was developed in view of these problems, and its main purpose is to allow the rear window to be stored separately from the top main body, while also allowing the rear window to close the top main body. The object is to be set at a predetermined position in conjunction with the movement.

Another object of the present invention is to ensure that even if the rear window is attached to a flexible top body and is heavy, such as made of glass, it will be securely held in place. It is to do so.

(Means for Solving the Problem) In order to achieve this object, in the present invention, the area around the rear window on the rear surface of the hood body is moved against the hood body at the upper edge and both side edges of the rear window. At the same time, the rear window and the front part of the link frame that supports the top body are connected by a belt that is separate from the top body, and the belt is connected when the top is opened and closed. It is designed to be folded separately from the canopy body, or to be stretched along the inner surface of the canopy body.

The belt is preferably elastic so as to be able to hold the rear window under tension. Further, the belt is required to have sufficient strength and durability. As such a belt, a belt made of webbing made of nylon or the like with a part slackened and an elastic member such as a rubber band sewn to the slackened part can be used.

(Function) With this configuration, when folding the top, if the link frame is bent with the rear window separated from the top main body, the belt will slack and the rear window will separate from the top main body due to its own weight. and falls forward. In this way, the rear window is housed on the rear tray at the rear of the vehicle body. On the other hand, since the rear portion of the canopy main body can be bent at the middle portion, it can be folded arbitrarily.

When closing the top, the link frame is expanded to tension the belt and pull up the rear window. When the top is completely closed, the rear window is held in place along the rear portion of the top body by a tensioned belt.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The figure shows an embodiment of the rear window support device according to the present invention, and FIG. 1 shows the hood of a cabriolet car equipped with the rear window support device.
FIG. 2 is a cutaway side view of the hood main body, and FIG. 2 is a perspective view of the hood portion. Also, Figures 3 and 4
The figure is an enlarged detailed view of the main part, and Figure 5A,
B and C are schematic side views for explaining the function of the rear window support device.

As is clear from FIGS. 1 and 2, the vehicle body 1
The left and right quarter panels 1a each have a base plate 2 at a position slightly forward of the rear edge.
is becoming fixed. A principal lever 3 and a secondary lever 4 are each pivotally supported on the base plate 2 so as to be rotatable in the front-rear direction. A central lever 5 extending forward is rotatably connected to the upper ends of the principal lever 3 and the secondary lever 4, and a front lever 6 is rotatably connected to the front end of the central lever 5. There is. Also,
A front linkage 7 is rotatably supported at the middle of the front lever 6, and a rear linkage 8 is rotatably supported at the rear end of the front linkage 7. The front ends are rotatably connected. Further, both ends of a tie rod 9 are rotatably connected to the intermediate portion of the rear linkage 8 and the tip of the principal lever 3.

In this way, the central lever 5 and the front lever 6 provided on both left and right sides of the vehicle body 1 form a foldable roof side rail. These left and right front levers 6, 6 are connected and fixed to each other by a front cross member 10 fixed to their front ends and a front wing rib 11 fixed to an intermediate part, and the left and right rear linkages 8, 8 are connected to each other. , are connected and fixed by middle wing ribs 12. Further, a central wing rib 13 is fixedly provided at the upper end between the left and right principal levers 3, 3, and a lower end of a rear wing rib 14 is rotatably connected near the lower end.

In this way, the members shown by these symbols 3 to 14 constitute a link frame F that forms a foldable roof frame.

On this link frame F, a canopy body H is placed, which is made up of a heat insulating plate 15 made of a flexible cotton-like heat insulating material and a skin 16 made of waterproof cloth or the like. The heat insulating plate 15 has its leading end fixed to the front cross member 10 and its rear end fixed to the rear wing rib 14. The skin 16 is fixed to the front cross member 10 and the rear wing rib 14 together with the heat insulating plate 15 at its leading end and at a position closer to the rear of the middle part, and its rear end is fixed to the rear upper edge of the vehicle body 1. In this way, the hood body H has a roof portion _H1 that covers from the front cross member 10 to the rear wing rib 14, and a rear surface portion _H2 that covers the area from the rear wing rib 14 to the rear upper edge of the vehicle body. It is becoming more and more common.

The rear surface _H2 of the hood main body H has a double structure consisting of an inner skin 16a having a large opening and an outer skin 16b covering the upper and both sides of the inner skin 16a. 17 is attached. This rear window 17 has a window glass 17a and a glass frame 17b that holds the periphery of the window glass 17a.As is clear from FIG. It is becoming fixed. As is clear from FIG. 2, the central part of the inner skin 16a to which the rear window 17 is attached is separate from the left and right parts, and these are connected to the fasteners 18.
are separably joined by. The upper end of the central portion is also separated from the outer skin 16b, and normally the upper edge thereof is held in contact with the inner surface of the outer skin 16b.
In this way, the peripheral portion including the rear window 17 can be separated from the top body H.

As shown in FIG. 3, one end of a belt 19 is fixed to the upper edge of the glass frame 17b. This belt 19 is guided forward from the upper part of the rear wing rib 14 through between the skin 16 and the heat insulating plate 15, and as is clear from FIG. 2, its front end is fixed to the middle wing rib 12. . Therefore, the belt 19 is
It is designed so that it can be deformed separately from the hood body H. The belt 19 may be made of webbing made of nylon or the like used in seat belts.
It is made of webbing with excellent strength and durability, and a portion thereof is provided with a slack portion 19a as shown in FIG. 4. An elastic member 19 such as a rubber band that can be stretched by an amount commensurate with the slack is placed between both ends of the slack portion 19a.
b is stretched by sewing or the like. In this way, the belt 19 is made elastic,
When the link frame F is in the unfolded state, the rear window 17 can be held with a predetermined tension. Moreover, by doing this, even if the elastic member 19b is cut, the rear window 17 is held by the strong webbing.

Next, the function of the hood of the cabriolet vehicle configured as described above will be explained.

As shown in FIGS. 1 and 2, when the top is closed, the principal lever 3 and the secondary lever 4 are rotated furthest forward, and the link frame F is in an expanded state. The front end of the link frame F is locked to the upper end of the front pillar of the vehicle body, and the link frame F forms a roof frame.
The canopy body H installed on the frame F completely covers the upper and rear surfaces of the vehicle body, and the interior of the vehicle is hermetically sealed with door glass and quarter glass, just like in a normal automobile. There is.

In this state, as is clear from Figure 5A,
From middle wing rib 12 to rear window 17
The length leading up to is the longest. At this time, the elastic member 19b of the belt 19 is stretched the most. On the other hand, the lower side of the rear window 17 is fixed to the vehicle body 1 via the lower end of the hood body H. Therefore, the rear window 17 is held under tension by the tension of the belt 19.

When opening the top, first open the rear window 17.
Remove the fasteners 18 on both sides of the rear window 17 and separate the rear window 17 from the top body H. and,
Push up the front lever 6 at the front end of the link frame F. Then, the rear linkage 8 gradually rises via the front linkage 7, and the tie rod 9 is pushed rearward, so that the principal lever 3 and the secondary lever 4 rotate rearward. Accordingly, the distance between the principal lever 3 and the rear wing rib 14 becomes narrower. This movement of the link frame F shortens the distance between the middle wing rib 12 to which the front end of the belt 19 is fixed and the upper edge of the glass frame 17b of the rear window 17 to which the rear end is connected, so that the belt 19 Due to its own weight, the rear window 17 sag and separates from the rear surface _H2 of the top body H.
It falls forward as shown in Figure 5B.

Next, from the rear, central wing rib 13
When the principal lever 3 and the secondary lever 4 are rotated backward, the link frame F is completely folded, as shown in FIG. 5C. At this time, there is sufficient room in the belt 19, so that the rear window 17 is stored on the rear tray of the vehicle body 1. Then, the rear surface portion _H2 of the hood main body H is folded between the rear wing rib 14 and the vehicle body 1.
In addition, the heat insulating plate ₁₅ of the roof portion H1 of the canopy body H is
It is folded up between the front lever 6, central lever 5, etc. while being held down by the belt 19. The skin 16 of the roof part _H1 is pulled out rearward and folded, and then stored between the front lever 6 and the central lever 5.

The top completely folded in this way is stored by locking the link frame F to the vehicle body 1 using a suitable locking device and then covering it with a top cover.

When closing the top, the top cover is removed, the locking device of the link frame F is removed, the front cross member 10 is pushed up from the rear, and the central wing rib 13 is pushed up. As a result, the link frame F is gradually unfolded, and the hood main body H is also unfolded. At this time, the distance between the middle wing rib 12 to which both ends of the belt 19 are connected and the upper edge of the glass frame 17b of the rear window 17 becomes longer, so the rear window 1
7 is pulled up by the belt 19 and gradually stands up.

When the link frame F is fully expanded and its tip is locked to the front pillar of the vehicle body 1, and the hood is completely closed, the belt 19 is in its most extended state and the rear window 17 is in a predetermined position. It will be set to . Therefore, close the fastener 18 and open the rear window 17 and the hood body H.
to combine.

In this way, the rear window 17 is retracted or set at a predetermined position in conjunction with the opening and closing of the top.

In the above embodiment, the front end of the belt 19 is fixed to the middle wing rib 12, but it can also be fixed to the front wing rib 11 or the central wing rib 13. In addition, the belt 19 is installed to pass between the skin 16 and the heat insulating plate 15 so as to be as inconspicuous as possible from the inside of the vehicle, but it is necessary to allow the heat insulating plate 15 to be bent more freely. In some cases, the belt 19 may be provided on the lower surface side of the heat insulating plate 15.

Furthermore, the upper side of the rear window 17 is always separated from the top body H, and only the left and right sides are separably joined by the fasteners 18, but the corners are not engaged. By using fasteners that can be easily removed, the rear window 17 can be separably connected to the top body H at both left and right sides and at the top using a single fastener. Further, a velvet fastener or the like may be used as long as it can withstand the weight of the window glass or the like.

(Effects of the invention) As is clear from the above explanation, according to the invention, the rear window provided on the rear surface of the canopy body is attached so as to be separable from the canopy body, and
The rear window and the front part of the link frame that is folded when the top is opened are connected by a belt that is separate from the top itself.
When the top is folded, the rear window is stored independently of the top, and the top can be folded at any position. Therefore, the top can be folded compactly and stored, and when the top is closed, the rear window is pulled up and set in a predetermined position as the link frame is expanded.

By using an elastic belt and holding the rear window in a tensioned state, the rear window can be reliably held at a predetermined position.
