It is known that a fluttering sound is sometimes prevented from occurring and a bellows-like portion is regularly folded when the canvas is folded.

The folding mechanism includes a front aggregate that is guided in the guide rail and moves only in the same direction as the plurality of aggregates that are arranged in the width direction of the canvas vehicle and are provided at predetermined intervals in the front-rear direction of the vehicle body. A link that is configured by alternately arranging a rear aggregate that is not guided by a rail and that can move upward, and further has a pair of front aggregates and rear aggregates with side end portions having engaging portions (e.g., long holes). In addition to being connected by a member, an engaging portion is provided which interposes a slider guided by a guide rail and which engages an engaging portion of the link member when the canvas is closed and restricts upward movement of the link member. .

[Problems to be Solved by the Invention] However, in the folding mechanism, since brackets and the like have to be interposed in order to connect the front and rear aggregates by the link member, the number of parts is large and the proportion is complicated accordingly. As a result, the number of assembling work increases and the cost becomes a problem.

The present invention has been made in view of the above problems, and an object thereof is to provide a canvas top structure for an automobile, which has a simple structure and can fold the canvas regularly and smoothly to improve appearance and the like. To do.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a canvas that covers an opening provided on a roof of a vehicle body so as to be openable and closable on guide rails provided on both sides of the opening in the front-rear direction. In the canvas top structure of an automobile, which is movable along one side of the opening from the other side toward the other side, and can be folded and folded in sequence in a bellows-like manner, the folding mechanism is fitted to the guide rail. And a valley-folding member integrally fixed to an end of a support shaft provided in the width direction of the back surface of the canvas, a roller portion fitted to the guide rail, and fixed to one end surface of the roller portion. In addition to having an arm protruding from the guide rail, it interlocks with the expansion and contraction operation of the canvas,
A plurality of mountain-folding members, which are rotatably provided so that the arms are displaced from the substantially horizontal position with respect to the guide rail via the roller part to a substantially upright position where the canvas is pushed up from below, are alternately arranged. It is a thing.

[Operation] According to this configuration, when one end of the canvas is moved to the other end and folded and contracted into a bellows shape, the mountain folding member of the folding mechanism is rotated and the canvas is folded by the arms. The valley folds are formed between the mountain folds by the valley fold member while forming the folds. Therefore, the mountain-folding member and the valley-folding member alternately and regularly form the mountain-folding portions and the valley-folding portions, so that the mountain-folding portions and the valley-folding portions can be neatly folded into a bellows shape and can be retracted. In addition, since the folded state can be mechanically maintained by the mountain folding member and the valley folding member even after the contraction, the shape is not deformed even when subjected to vibration during traveling.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 schematically show an automobile to which an embodiment of the present invention is applied.

As shown in the figure, in the upper vehicle body of the automobile 1, the roof 2 has an opening 3 formed over substantially the entire surface except the periphery. In addition, the roof 2 remaining on the front side of the opening 3
A front deflector 5 having a front surface smoothly extending from the front window 4 is attached to a peripheral portion of the. Further, guide rails 6 to which a canvas 7 is movably attached are provided on both left and right sides of the opening 3 via a folding mechanism 40 described later.
The pair of guide rails 6 are fixed to the roof 2 respectively,
They are arranged in parallel so as to extend in the front-rear direction of the vehicle body, are formed in a substantially U-shaped cross section as shown in FIG. 3, and their opening sides are opposed to each other.

Next, the canvas 7 supported by the pair of guide rails 6
Is formed of a flexible cloth such as a flexible cloth or a sheet material such as vinyl chloride. A cover plate 9 is attached to the front end 7a of the canvas 7, the front end 7a is movable together with the cover plate 9, and the rear end 7b is provided with the opening 3a. It is fixed to the roof 2 with screws 24 at the rear. The canvas 7 has a plurality of intermediate portions that are bent so that it can be folded into a bellows shape, and the folding is regularly performed by the folding mechanism 40.

More specifically, the folding mechanism 40 is arranged corresponding to each inside of each guide rail 6, and the front roller 41 is
Member 42 for mountain folding, member 43 for valley folding, and wire 44
Etc.

The front roller 41 has support legs 45 which are arranged so as to protrude downward from both left and right sides of the cover plate 9.
Is rotatably attached to the guide rail 6 via a support shaft 46 and is slidably arranged in the guide rail 6. Further, a through hole (not shown) through which the wire 44 is passed is provided on the peripheral surface of the front roller 41.

The mountain folding member 42, as shown in detail in FIG.
Roller part 47 rollably arranged in the guide rail 6
And an arm portion 48 that is cantilevered and fixed to the roller portion 47 via a support shaft. The arm portion 48 is located on the outer side of the guide rail 6 and is arranged on the lower surface side of the canvas 7 in the area of the canvas 7.
The shape of b is formed to be gently inclined. Also, a through hole through which the wire 44 is passed is provided on the peripheral surface of the roller portion 47.
49 (see FIG. 3) is provided.

The valley-folding member 43 includes a roller 50 that is rollably arranged in the guide rail 6, and a support shaft 51 that projects from the inner surface of the roller 50 at a substantially right angle. The support shaft 51 is connected to the roller 50 of the valley-folding member 43, which is arranged to face the guide rail 6 on the opposite side. Also,
A through hole 52 (see FIG. 3) through which the wire 44 is passed is provided on the peripheral surface of the roller 50. The folding mechanism 40 including the front roller 41, the mountain-folding member 42, the valley-folding member 43, and the wire 44 arranges the front-side roller 41 first for each guide rail 6, and then performs the mountain-folding. Members 41 and valley-folding members 42 are arranged alternately. In this arranged state, the tip end 48c of the arm portion 48 is located above the support shaft 51. Also, at this time, wire 44
Are arranged in a state of being sequentially passed through the roller 41, the mountain-folding member 42, and the valley-folding member 43.The tip is fixed to the front roller 41, and the end is drawn into the vehicle body and is not shown. It is connected to the drive mechanism. On the other hand, with respect to the folding mechanism 40 configured as described above, the canvas 7 is arranged so that the folding mechanisms 40 are located on the lower surfaces of both left and right sides of the canvas 7, as shown in FIG. The support shaft 51 that crosses the canvas 7 in the left-right direction is
It is passed through a tubular portion 53 formed by sewing an auxiliary cloth 52 on the lower surface side of the canvas 7 and integrated with the canvas 7.

The operation of the canvas top structure thus constructed will be described below.

First, as shown in FIG. 1, when the canvas 7 is expanded and the opening 3 is closed, the front end 7a is moved forward together with the guide plate 9 and locked.
In addition, the front roller 41 that moves integrally with the guide plate 9
By the movement of the wire 44, the wire 44 is pulled out to the front side as shown in FIG.
3 has been moved to the front. The arm portion 48 of the mountain-folding member 42 is rotated clockwise with the roller portion 47 in FIG. 6 so that the upper surface 48a is arranged in a horizontal state and the tip end 48c is a valley-folding member 43. It is arranged at a position where it does not overlap the support shaft 51 of.

Next, when the opening 3 is opened, when the wire 44 is pulled to the rear end side in the state where the lock is unlocked, the pulling force of the wire 44 moves the front roller 41 to the rear end side. At this time, the front roller 41 pushes the roller portion 47 of the mountain folding member 42 adjacent to the front roller 41. Then, the roller portion 47 starts moving to the rear end side together with the front roller 41. And the tip of the arm 48
When 48c overlaps the support shaft 51 of the valley-folding member 43, a part of the canvas 7 is pushed from the support shaft 51 to the rear end side. Then, the arm portion 48 receives the force of rotating in the counterclockwise direction to rotate, and pushes up a part of the canvas 7 as shown in FIG. 6 (b). This operation is sequentially transmitted to each mountain folding member 42.
Also, when the wire 44 is further pulled to the rear end side, the arm 48
Is further rotated, and as shown in FIG. 6 (c), the canvas 7 is neatly folded into a bellows shape and is neatly retracted to the rear end to maintain this state. In this contracted state, the mountain fold portion is tilted rearward, and this inclination rectifies the air during traveling.

Next, when the canvas 7 is expanded again, the front end portion 7a of the canvas 7 is pulled forward together with the cover plate 9, and the front roller 41 moves and at the same time the canvas 7
Is pulled toward the front side, the mountain folding member 42 and the valley folding member 43 are also sequentially moved to the front side. Then, at this time, the arm portion 48 of the mountain-folding member 42 also pivots back in the clockwise direction,
By returning to the state of FIG. 6 (a), the canvas 7 can be expanded as shown in FIG.

Therefore, in this canvas top structure, when the canvas 7 is folded, the folding mechanism 40 always folds it in a bellows-like manner regularly so that the appearance is improved. In addition, since the folded state is mechanically maintained by the folding mechanism 40 even after the contraction, it does not collapse due to vibration during traveling, and it is possible to suppress the occurrence of the fluttering sound of the canvas.

In the above embodiment, the structure in which the folding mechanism 40 is operated by the wire 44 at the time of folding is described, but it is not always necessary to use the wire. Of course, the mountain-folding member 42, the valley-folding member 43, etc. can be variously modified within the scope of the present invention.

[Effects of the Invention] As described above, according to the canvas top structure for an automobile of the present invention, when one end of the canvas is moved to the other end and folded in a bellows shape to be contracted, the folding mechanism is piled up. The folding member is rotated to form a mountain folding portion on the canvas, and the valley folding member is formed between the mountain folding portions by the valley folding member. Therefore, the mountain-folding member and the valley-folding member alternately and regularly form the mountain-folding portions and the valley-folding portions, so that the mountain-folding portions and the valley-folding portions can be neatly folded into a bellows shape and can be retracted. In addition, since the folded state can be mechanically maintained by the mountain folding member and the valley folding member even after the contraction, the shape is not deformed even when subjected to vibration during traveling.

As a result, the present invention has a simple structure and can improve the appearance, and can improve the riding comfort by eliminating the fluttering noise during traveling.
