DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a canvas top structure for an automobile.

[Prior Art] Conventionally, a canvas top vehicle in which an opening is formed in a roof of a vehicle body and the opening is opened or closed by a canvas is known from, for example, Japanese Utility Model Publication No. 61-36438. ing.

By the way, in this type of canvas top vehicle, guide rails are provided on both sides of the opening in the vehicle width direction, and canvases that can be stretched or retracted are provided along the guide rails in the front and rear of the vehicle body. Then, the canvas is expanded or contracted and displaced by a drive mechanism having a motor or the like to open or close the opening.

FIG. 7 is a sectional view schematically showing an opening / closing structure of a canvas in such a conventional canvas top vehicle.
The figure is a perspective view showing an example of the canvas.

In the figure, the canvas 41 is formed of a flexible cloth or the like. Also, the front end portion 41 of the canvas 41
Reference numeral a denotes a cover plate, and rollers 43 are rotatably provided on both sides of the front end portion 41a. Then, a roller 43 is rotatably arranged on a guide rail (not shown) arranged inside an opening (not shown) covered by the canvas 41, and the rolling of the roller 43 causes the front end portion 41a of the canvas 41 to roll. Can be moved back and forth. On the other hand, in the rear end portion 41b of the canvas 41, a mounting hole 41c that is screwed to the rear end of the vehicle body 44 via a screw 45.
The rear end portion 41b of the canvas 41 is fixed to the rear end of the vehicle body 44 via the screw 45.

In this conventional structure, when the canvas 41 is expanded, the front end portion 41a is pulled out to open the opening portion of the canvas 41.
Is covered with the whole body, and further, the front end portion 41a is releasably locked on the front end side of the vehicle body. Next, when this lock is released, the front end portion 41a can be moved to the rear end portion 41b side by the engagement of the guide rail and the roller 43. Further, at this time, the canvas 41 is formed in advance so as to be bent and folded in a bellows-like manner at a portion 42. The intervals between the bent portions 42 are formed to be substantially equal, and when the front end 41a is pushed toward the rear end 41b,
With this pushing force, it is sequentially folded and retracted.

[Problems to be solved by the device]

However, in this conventional structure, there is no means for positioning and holding the sequentially folded portions in a bending manner. For this reason, as shown in FIG. 7, there is a problem that it is folded in an irregular state, or the folded state is collapsed due to vibration during traveling, and the appearance is deteriorated.

Further, since the spaces between the bent portions 42 are formed to be substantially equal to each other, in the retracted state, the whole is arranged in a state of standing upright at a substantially right angle to the vehicle body 44. Therefore, when the canvas 41 is retracted as shown in FIG. 7 and the vehicle travels, the wind hits the front end portion of the canvas 41 at a right angle to increase air resistance and deteriorate fuel efficiency. In addition, "bo,
When air column resonance such as "bo, bo, ..." Occurs or an irregular folded state occurs, there is a problem that a fluttering sound is generated on the canvas 41 and the riding comfort becomes poor.

The present invention has been made in view of the above problems, and its purpose is to have a structure in which the canvas can be smoothly and neatly retracted to the rear side, and the occurrence of air column resonance and fluttering noise can be eliminated. It is to provide a canvas top structure for automobiles.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a canvas top structure in which a canvas that slides in the front-rear direction of a vehicle body while being folded in a bellows shape is arranged in an opening provided in a roof, and is folded in the bellows shape. Provided on the canvas portions facing each other in a folded state, and having thin shape small plate-shaped shape retaining members capable of disengaging each other, when the canvas is folded in a bellows shape, the shape retention members are It engages and holds the folded state of the canvas.

[Operation] According to this configuration, when one end of the canvas is slid to the other end and folded and contracted into a bellows shape, the crease is determined by the shape-retaining member provided on the canvas.
It is regularly folded and held at this predetermined position. Therefore, the canvas can be smoothly and neatly folded. As a result, the shrinking work of the canvas can be performed quickly and the workability is improved, and the canvas can be neatly folded to improve the appearance. Further, there is no fluttering sound generated from the canvas when the vehicle is running, so that the riding comfort can be improved and the fuel consumption can be improved.

[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.

On the other hand, guide rails 6 are provided on both left and right sides of the opening 3. In addition, canvas 7 is attached to this guide rail 6.
However, the roller 20 which is guided by the guide rail 6 and rolls
The front end portion 7a is movably attached to the rear end portion 7b through (see FIGS. 3 and 5). Then, the canvas 7 is stretched or contracted and displaced on the opening 3 in the front-rear direction of the vehicle body, and the opening 3
It has a structure to open or close the lid.

More specifically, as shown in FIG. 5, the canvas 7 is formed of a flexible cloth that can be bent freely or a sheet material such as vinyl chloride. Also, the canvas 7 is bent at the middle portion at each portion 8 so that it can be folded into a bellows shape, and the distance between the adjacent portions 8 and 8, that is, the folding width dimension is shown in FIGS. 4 to 5. As shown in FIG. 5, the holes are formed in such a state that they gradually become smaller as they progress from the front end 7a to the rear end 7b. Further, a plurality of shape-retaining members 30 are provided on the outer surface on both the left and right sides of the canvas 7 in a scattered manner. Each of the shape-retaining members 30 uses a magic fastener (registered trademark) that can be brought into and out of contact with each other, and is in a state of forming a pair with a surface facing each other when the canvas 7 is folded with a predetermined folding width. , And are fixedly adhered to the facing portions, respectively. Therefore, the canvas 7 has a predetermined position, that is, the shape-retaining members 30, 30.
When the comrades are folded in a bellows shape at the corresponding positions and retracted, the shape-retaining members 30, 30 are engaged with each other and the folded state is maintained. On the contrary, when shifting to the expanded state, a tensile force larger than the engaging force is applied between the shape-retaining members 30, 30 which are engaged with each other, and the shape-retaining members can be released. It has become. Inside the front end 7a of the canvas 7, a cover plate 9 (see FIG. 5) is arranged over the left and right ends so as to extend in the vehicle width direction along the edge of the front end 7a. Has been done. Support legs 21 (see FIGS. 3 to 5) are provided on both left and right ends of the cover plate 9, and the rollers 20 are rotatably provided on the outer sides of the support legs 21 via support shafts 22, respectively. It is installed. On the other hand, the rear end 7b of the canvas 7 is provided with a mounting hole along the edge of the rear end 7b.
A plurality of 23 are formed scattered in the vehicle width direction. And
The canvas 7 has a rear end 7b fixed to the rear portion of the roof 2 via a screw 24 (see FIG. 4) screwed to the roof 2 through a mounting hole 23, and a front end via a roller 20. And is slidably attached to the guide rail 6.

This guide rail 6 is, as shown in FIG. 3 as an enlarged sectional view of an essential part taken along the line AA in FIG. 1, a roof 2 including an outer panel part 2a, an inner panel part 2b and a sub plate 2c. Are supported by and are arranged along both left and right side surfaces of the opening 3. Each of the guide rails 6 has a guide groove portion 6a that is open toward the inside, and the roller 20 is rotatably arranged in the guide groove portion 6a. Then, due to this rolling, the front end portion of the canvas 7
7a is ready to slide on the opening 3. In addition,
In FIG. 3, a member indicated by reference numeral 25 is a molded ceiling plate, a member indicated by reference numeral 26 is a garnish, and a member indicated by reference numeral 27 is a weather strip that seals between the door glass 28 and the roof 2.

In the automobile 1 configured in this way, when the canvas 7 is expanded as shown in FIG.
7b is located on the roof 2 at the rear end of the opening 3, and
The front end portion 7a is located at the front end of the opening portion 3 and is locked (not shown) in a state of entering the front deflector 5.
Thereby, the opening 3 is covered with the canvas 7 and closed. Next, when opening the opening 3, the lock is released and the front end 7a is pushed toward the rear end 7b. Then, while the roller 20 rolls in the guide groove 6a, the front end 7a is moved rearward and the opening 3 is opened. At this time, the canvas 7 is gradually bent at the portion 8 and is folded into a bellows shape. In this canvas 7, the distance between the bendable portions 8, that is, the folding width dimension is the front end portion.
Since it is formed so that it becomes smaller from 7a toward the rear end 7b, when folded and folded into this bellows-like shape, the upper portion of the bent portion located on the front side is shown in FIGS. As shown in Fig. 4, the folded shape is folded toward the rear side and folded in the inclined state.
The spaces 30, 30 are engaged with each other, and the folded state is maintained. When the vehicle is run in this state, it can be run without being deformed by vibration or the like while being firmly held by the shape-retaining members 30, 30 in the folded state.
In addition, the portion that is bent in a state of being inclined at the frontmost side functions as a deflector, and the air flow hits this portion in a non-rectangular state to be rectified and the air resistance is weakened. Therefore, it is possible to improve the fuel efficiency and eliminate the air column resonance in the opening to improve the riding comfort. In addition, since the rear bent portion is pressed down from the upper side by the front bent portion, the entire canvas 7 is firmly and neatly folded and pressed while the holding members 30 and 30 are held, so that the running It is possible to further improve the riding comfort by eliminating the fluttering sound in. Next, when closing the opening 3 with the canvas 7 again, when the front end 7a of the canvas 7 is strongly pulled forward, the engagement between the shape-retaining members 30, 30 is released at the same time,
The canvas 7 is sequentially fed out from the front end portion 7a side. Then, when the front end 7a is pulled into the front deflector 5 and locked, the opening 3 can be returned to the closed state as shown in FIG.

In the above embodiment, the shape retaining member 30 is described as having a structure in which a magic fastener is attached to the outer surface of the canvas 7. However, the shape retaining member 30 is not limited to the magic fastener, and may be, for example, as shown in FIG. Alternatively, a permanent magnet or the like may be used.

That is, in the structure shown in FIG. 6, the shape-retaining member 30 as a permanent magnet is embedded in the portions of the canvas 7 that face each other when the canvas 7 is folded with a predetermined folding width. Therefore, in the canvas 7 shown as this modified example, the predetermined position, that is, the shape-retaining members 30, 3
When the comrades are folded into a bellows at the corresponding positions and retracted, the shape-retaining members 30, 30 are held by being engaged with each other by magnetic attraction. Further, in this structure, even if the bellows-like folded state is slightly collapsed and folded, it can be self-corrected to a predetermined state by the suction force between the shape retaining members 30 and held. On the contrary, when shifting to the expanded state, a pulling force larger than the suction force is applied between the shape-retaining members 30, 30 that have been suction-engaged, and the shape-retaining members can be released. .

In the above, an example was described in which the distance between adjacent parts 8,8, that is, the folding width dimension, was formed such that it gradually decreased as it went from the front end 7a to the rear end 7b. Set the parts 8 and 8 to be evenly spaced,
The folding width may be the same.

[Effects of the Invention] As described above, according to the canvas top structure for an automobile according to the present invention, when one end of the canvas is slid to the other end and folded in a bellows shape to be contracted, the canvas is provided on the canvas. The fold line is determined by the shape-retaining member, and the fold line is properly folded and held at this predetermined position. Therefore, the canvas can be smoothly and neatly folded. As a result, the shrinking work of the canvas can be performed quickly and the workability is improved, and the canvas can be folded neatly to improve the appearance. Further, the fluttering sound generated from the canvas during walking is eliminated, so that the riding comfort can be improved and the fuel consumption can be improved.
