Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a device for preventing wind entrainment in convertible cars. This invention relates to a device that can prevent this.

[Conventional technology]

Generally, in a vehicle equipped with a folding top that can open and close the upper part of the passenger compartment, such as a cabriolet, the top is locked to the upper edge of the front window when it is in the closed position of the passenger compartment, covering the upper part of the passenger compartment. When the vehicle is in the open position, it can be folded and stored on the upper surface of the rear of the vehicle. Therefore, when the vehicle is traveling with the cabin open, the wind is blocked only by the front window.

Incidentally, in such a cabriolet vehicle, the front window cannot be made very high from the viewpoint of styling or reducing air resistance. Therefore, when driving with the cabin open, a portion of the airflow pushed upward by the front window becomes a vortex that swirls downward near the rear seat, causing discomfort to the occupants. be.

To solve this problem, for example, by installing an air deflector that protrudes upward from the upper edge of the front window,
Some devices are designed to further deflect the airflow created by the front window upwards.
However, if you do this, the deflector will get in the way when you close the top, and each time you close it,
There is the operational hassle of having to remove the deflector.

On the other hand, since the deflector is subjected to strong wind pressure while the vehicle is running, it is necessary to make the attachment part strong. Therefore, a complex and strong structure is required to provide a detachable structure, which is not easy to realize. Another disadvantage is that a separate space is required to store the removed deflector.

In an attempt to resolve this issue,
For example, there is an airflow deflection device described in Publication No. 59121/1983. This is provided with a deflector that can be raised and lowered at the top of the front window, so that the deflector can be projected from the upper edge of the front window by simply opening and closing the top, and can be easily folded when stored.

[The problem that the idea aims to solve]

As mentioned above, if a deflector large enough to allow the wind to flow smoothly to the rear of the vehicle body is provided at the top of the front window, it cannot be denied that this will be disadvantageous in terms of styling and air resistance, as described above. Furthermore, in the latter case, when the vehicle is driven with the top closed, the deflector is lowered and placed above the front window, creating a feeling of a foreign body, which impairs the sense of openness that can be obtained through the front window.

For this reason, it is recommended to leave the front window as it is and to block the part of the airflow pushed upward by the front window from forming a vortex behind the seat and flowing forward. A suitable method is desired.

By the way, Japanese Patent Laid-Open No. 61-247515 describes an automobile in which the roof can be opened and closed by moving two cover members disposed at the front and back, which cover the upper part of the vehicle body in an openable and closable manner.

In such vehicles, the openable roof consists of a hard roof that covers directly above the passenger compartment and a member that covers the rear of the passenger compartment, and a link member that rotates back and forth when opening and closing the roof. It is equipped with

In the roof opening/closing position where such a structure is adopted, if the link member can be held in that position when it comes to the intermediate position between the upright position and the stowed position, it will be possible to prevent the hard roof from getting caught in the wind. It can be made to function as a shielding member.

In such a device, if a solution is proposed to ensure that the attitude of the hard roof is maintained at the above-mentioned intermediate position, the above-mentioned problems will be solved. However, there is still no such concrete measure, and it is desired to devise a suitable means for holding the shielding member in order to prevent wind entrainment.

The present invention was developed in consideration of these circumstances, and its purpose is to use a hard roof as a shielding member to prevent wind from entering the roof without adopting any new members. To provide a wind entrainment prevention device for an open car, which effectively maintains the attitude and fixed state of a hard roof and also enables the release of the hard roof.

[Means to solve the problem]

The present invention allows the roof portion to take a closed position of the passenger compartment, covering the upper part of the passenger compartment, and also to take a storage position in which the roof part is stored in the rear part of the vehicle body when the upper part of the passenger compartment is opened, leaving at least the front window part. This applies to convertible cars whose roof portion covering the passenger compartment has at least a hard roof.

Its characteristics are as shown in Figure 1.
The roof part 3 is foldable behind the seat 5, and link members 6 for opening and closing the roof part 3 are provided on both sides of the vehicle body.

The above-mentioned state in which the roof part 3 is held at a position between the vehicle compartment closed position and the stowed position and tilted behind the seat 5, and the state in which the roof part 3 is released from the held position are held. A holding mechanism 8A is provided that changes its operation so as to realize this, and when the roof portion 3 is in the attitude holding state, the hard roof 4 can block airflow from the rear toward the seat 5 side. That's what I did.

[Effect]

A roof part 3 including a hard roof 4 is opened and closed by link members 6 provided on both sides of the vehicle body. When the roof part 3 is retracted to open the upper part of the passenger compartment, leaving at least the front window part, the roof part 3 is in a folded state, and the hard roof 4 is held in an inclined state behind the seat 5 by the holding mechanism 8A. Ru.

When driving at high speed in such conditions, the hard roof 4 prevents the front window portion 1 from closing.
A part of the airflow that exceeds the distance tends to flow toward the seat 5 from the rear, but this is effectively prevented.

On the other hand, when the roof part 3 assumes the cabin closed position covering the upper part of the cabin 2, by releasing the holding position by the holding mechanism 8A, the link member 6 can be returned to the upright position and the roof part 3 can be expanded. I can do it.

[Effect of idea]

According to the present invention, when the roof section is retracted, the hard roof is held in an inclined state behind the seat by the holding mechanism, and a part of the airflow that crosses the front window section is prevented without providing a new shielding member. Even the hard roof can prevent the fluid from forming a vortex flowing forward on the upper surface of the rear portion of the vehicle body and flowing into the seat side. the result,
This prevents the luggage on the seat side from scattering or from lowering the sensible temperature of the occupant sitting on the seat.

In addition, when the holding mechanism releases the roof from maintaining its posture, the roof portion can be expanded to cover the upper part of the vehicle interior.

〔Example〕

The present invention will be described in detail below based on examples.

As shown in FIG. 1, the wind entrainment prevention device for a convertible car shown in this example is designed so that a passenger compartment 2 is opened upward, leaving a front window part 1, and the passenger compartment 2 is covered. The present invention is applied to a two-seater open car in which the first half of the roof part 3 is formed of a hard roof 4. This means that the roof part 3 is
It is possible to take a closed position in the passenger compartment covering the upper part of the vehicle, and also to take a storage position in which it is stored inside the passenger compartment.

Link members 6 formed by forming bars or the like that open and close the roof part 3 are provided on both sides of the rear part 7 of the vehicle body, and the roof part 3 is folded and stored behind the seat 5 as shown by the dashed line. It has become freely possible. A holding mechanism 8A is provided that holds the hard roof 4 in an inclined state behind the seat 5 as shown by a solid line when the roof portion 3 is stored.

Hard roof 4 forming the first half of the roof part 3
The rear end is connected to the link member 6 by the hinge 11.
The front end is connected to the upper edge of the front window portion 1 when the vehicle compartment 2 is closed. And rod 12, 13
When the link member 6 is rotated in the front-rear direction about a support shaft 15 fixed to the rear part 7 of the vehicle body by the motor 14 via the
Together with the top 16 forming the rear half of the rear floor 17, it is extended as shown by the two-dot chain line, or folded onto the upper surface of the rear floor 17, as shown by the one-dotted chain line.

On the other hand, the holding mechanism 8A that holds the link member 6 in the inclined state as shown by the solid line is in the inclined state behind the seat 5 when the roof portion 3 is in a position between the compartment closed position and the storage position. It has a function of holding the hard roof 4 in such a manner that the hard roof 4 is held in the same position as shown in FIG.

As shown in FIG. 3, one end of a rod 20 is pivotally attached to a support bracket 19 fixed to the rear inner wall surface 18 of the vehicle body so as to be rotatable within the plane of the drawing, and one end of a rod 21 is attached to the other end. Similarly, it is pivotally mounted so as to be freely rotatable along the plane of the paper. That rod 2
A stopper pin 22 is fixed to the other end of 1,
It can be engaged with either of the receiving members 23 and 24 which are spaced apart from each other on the rear inner wall surface 18 of the vehicle body.

Therefore, when holding the hard roof 4 in an inclined state, the rods 20 and 21 are made to protrude inward to form a right triangle as shown by solid lines, and the stopper pin 22 is held in the receiving member. Lock it to 23. After doing this, the motor 14 is rotated to rotate the link member 6 rearward, and the hard roof 4 is folded.

When the hard roof 4 is in a position slightly tilted rearward as shown by the solid line in FIG. 1, the link member 6 comes into contact with the rod 20. At this time, the motor 14 is stopped and the link member 6 is stably held by the rod 20 in a slightly collapsed state. That is, by maintaining the hard roof 4 in a slightly rearwardly inclined state, the rear of the seat 5 can be shielded in the vehicle width direction, as shown in FIG. 4.

As described above, the roof part 3 is retracted so that the hard roof 4 is slightly inclined backward, the front window part 1 is left, and the vehicle is driven at high speed with the vehicle interior 2 opened upward. As shown in Figure 2,
A part of the airflow 9 that has passed over the front window portion 1 becomes a vortex 10, and as shown by the broken line, it tries to be drawn into the seat 5 from the rear.

However, the hard roof 4, which is held in a slightly rearwardly inclined position as shown by the solid line, prevents the vortex 10 from turning rearward as shown by the solid line and flowing into the seat 5 side.

Furthermore, although not shown, the airflow that has passed through both sides of the front window portion 1 surrounds the occupant seated on the seat 5 from the side, goes around behind the occupant, passes between them, and flows forward. , an attempt is made to generate an air flow that flows backward inside the front window portion 1. Similar to the vortex 10 described above, such an air flow scatters luggage on the seat 5 side and lowers the perceived temperature of the occupants in winter, but it is also caused by the hard roof 4 held in an inclined position. As a result, forward entry is blocked.

FIG. 5 shows a different embodiment from the above, and shows a holding mechanism 8B that can be housed in a recess 25 provided in the rear inner wall surface 18 of the vehicle body rising from the rear floor 17 (see FIG. 1).

This includes a holding rod 27 having a receiving surface 26 formed at its tip for receiving the link member 6, and its base end is pivoted to one end of a fan-shaped recess 25 formed in the rear inner wall surface 18 of the vehicle body. There is. The holding rod 27
is rotatable in the plane of the drawing and is biased toward the inside of the vehicle body by a spring 28 whose one end is fixed within the recess 25.

A locking recess 29 is provided adjacent to the receiving surface 26 at the tip of the holding rod 27, and a locking recess 29 is provided on the rear inner wall surface 18 of the vehicle body.
A locking convex portion 30 protrudes from the inside of the concave portion 25.
by engaging the retaining rod 27 with the rear inner wall surface 18 of the vehicle body.
It is designed so that it can be locked in a state where it is aligned with the

A handle 31 is attached to the back of this locking recess 29, and by bending a curved portion 32 formed slightly thin so as to have some elasticity, the holding rod 27 can be locked and released. I'm starting to be able to do it.

On the other hand, a holding rod 27 is provided which is biased by a spring 28 in the direction of arrow 33, which is the inside direction of the vehicle body.
It is designed so that it can be locked in a position where it can be received. To this end, a locking piece 34 that contacts the locking protrusion 30 from inside the recess 25 is connected and fixed to the holding rod 27 via a substantially triangular base plate 35.

In the case of such a holding mechanism 8B, the handle 3 of the holding rod 27 is in the retracted state as shown by the two-dot chain line.
1 and bend the curved portion 32 to release the locking recess 29 from the engagement with the locking protrusion 30, and the holding rod 27 is rotated to the position indicated by the solid line by the bias of the spring 28. let The locking piece 34 comes into contact with the locking protrusion 30, and the holding rod 27 is stably locked at that position while being biased in the direction of the arrow 33 by the spring 28.

In such a state, the link member 6 is stably held in a slightly tilted rearward state, as shown by the solid line in FIG. 1, and the hard roof 4 can be maintained in a desired tilted state.

When storing, move the outer part of the holding rod 27 in the direction of arrow 3.
3 in the opposite direction, it can be pushed into the recess 25 while resisting the bias of the spring 28. The curved portion 32 is forcibly bent while the back of the curved portion 32 is in sliding contact with the locking convex portion 30, the locking convex portion 30 is fitted into the locking recess 29, and the holding rod 27 is moved as shown by the two-dot chain line. stored in a state. In this way, this example has the advantage that it is extremely easy to handle by operating the handle 31.

FIG. 6 shows a further different embodiment in which the hard roof 4 is tilted rearward as shown by the solid line by providing an outer cylinder 38 that straightens the rods 36 and 37 that connect the link member 6 and the hard roof 4. This is a holding mechanism 8C that is capable of holding the device in a certain position.

One end of the rod 36 is rotatably connected to the hard roof 4 via a bracket 39, while one end of the rod 37 is rotatably connected to the link member 6 via a bracket 41. As shown in FIG. 7, the other end of the rod 36 is connected to the pin 4.
It is rotatably connected to the other end of the rod 37 via 0. An outer cylinder 38 is slidably fitted into both rods 36 and 37, and V-shaped leaf springs 42 and 43 are attached to both ends of the outer cylinder 38.
is installed.

When both rods 36 and 37 are stretched straight, when the outer cylinder 38 is placed in the position shown by the solid line so as to cover the pin 40, the leaf spring 42
and 43 engage with a V-shaped groove 44 provided at the other end of the rod 36 and a V-shaped groove 45 provided at the other end of the rod 37, and the outer cylinder 38 is fixed at that position, and both rods are 36 and 37 are held straight.

In this state, as shown by the solid line in FIG.
When hooked to the stopper 46 provided above, the hard roof 4 is tilted slightly rearward to be in a stable retracted state. Similar to the previous example, it is possible to effectively prevent the vortex 10 from flowing from the rear toward the seat 5 side.

On the other hand, as shown by the two-dot chain line in Fig. 7, the rod 3
6 relative to the rod 37, the outer cylinder 38 is moved toward the rod 37, and the leaf springs 42 and 43 are engaged with V-shaped grooves 46 and 47 formed near the other end of the rod 37, respectively. , the outer cylinder 38 may be fixed at that position.

By the way, in order to put the hard roof 4 in the extended state into the tilted retracted state as described above, first,
The link member 6 is rotated to the retracted position shown by the solid line in FIG.
It is hooked onto the upper stopper 46. Lift the hard roof 4 at its rear to the inclined position shown by the solid line, keep both rods 36 and 37 straight, slide the outer cylinder 38 to the position shown by the solid line in FIG. 7, and fix it. .

In the embodiments described above, the holding mechanism that holds the hard roof in an inclined state behind the seat is operated manually, but the above-mentioned holding function can be performed using, for example, a motor or a hydraulic cylinder. You may also make it work. Further, the present invention can be applied not only to a two-seater convertible car but also to a four-seater convertible car.
