Description

TECHNICAL FIELD The present invention relates to a canvas top structure.

2. Description of the Related Art As a canvas top structure of an automobile, there is, for example, one shown in FIGS.

In FIGS. 6 and 7, a roof opening 3 is formed in a roof portion 2 of a vehicle body 1, and a canvas top body 4 made of cloth or the like is stretched so as to cover the roof opening 3.

The periphery of the roof opening 3 will be described with reference to FIG. 6 on the front side. A substantially crank-shaped frame 7 is arranged on the rear side of the roof panel 6 forming a closed cross-section structure portion by the front roof rail 5.

A sealing material 8 for sealing between the frame 7 and the roof panel 6 is additionally formed on the front edge of the frame 7, and the rear edge of the frame 7 is attached to a joint flange portion between the roof panel 6 and the front roof rail 5. Weather strip 9
At the same time, a welt 11 for sandwiching the suspended ceiling 10 is attached. A deflector 13 is attached to the roof panel 6 via a bracket 12.

On the other hand, the canvas top body 4 is
The outer cover 15 is wound around the front edge of the front cover 14 and adhered, and the interior material 17 is attached to the retainer 16 attached to the lower surface of the front cover 14. Atte, the seal material incidental to the front edge of the retainer 16 Watertightness is ensured by bringing 18 into close contact with the sealing material 19 attached to the frame 7.

A plurality of aggregates 20 are wound around the interior material 17 in the vehicle width direction to give a feeling of tension to the skin 15 (this similar structure is disclosed, for example, in Japanese Utility Model Publication No. 61-145027). ).

Problems to be Solved by the Invention When the vehicle is traveling, the negative pressure area generated on the surface of the canvas top body 4 tends to swell the canvas top body 4, particularly the outer skin 15, to the outside of the vehicle. May cause flapping, which may make passengers uncomfortable.

Further, the bulging of the skin 15 changes the positional relationship with the deflector 13 and deteriorates the aerodynamic characteristics, and vortex noise may occur in some cases.

Therefore, the present invention provides a canvas top structure that prevents swelling of the canvas top body to the outside of the vehicle and enables comfortable running.

Means for Solving Problems A strip-shaped tension member is stretched across the width of the vehicle on the back side of the canvas top body stretched over the roof opening of the vehicle body. It is cut inside the car and attached.

Function When the canvas top body tries to bulge out of the vehicle due to the negative pressure area generated on the surface of the canvas top body when the vehicle is running, the tension due to the tension material provided on the back surface of the canvas top body counters this and Prevent swelling.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings by assigning the same reference numerals to the same portions as those of the conventional configuration.

1 to 5, a front roof rail 5 is attached to a roof panel 6 of a vehicle body 1, a frame 7 having a substantially crank-shaped cross section is arranged, and a sealing material 8 is additionally formed on the front edge of the frame 7 to form a frame 7. The suspended ceiling 10 is sandwiched by welts 11 at the rear edge.

A roof opening 3 is formed in a portion surrounded by the front side portion of the roof configured as described above and both side portions of the roof (not shown) and the roof rear side portion, and the canvas top main body 4 is attached thereto. Reference numeral 13 represents a deflector.

The canvas top main body 4 has a front cover 14 forming a front side, and a skin 15 wound around the front cover 14 to be adhered and folded back. A retainer 16 attached to the lower surface of the front cover 14 has a frame 7 at the front edge thereof. A seal material 18 that is in close contact with the seal material 19 is attached. Also,
An interior material 17 is attached to the rear edge of the retainer 16.

Here, a curved portion 21 that bulges downward is formed at the rear edge of the front cover 14, and a cover cloth 22 is attached to this curved portion 21.

Further, a reinforcing member 23 welded to the outer skin 15 by hot melt or the like is interposed between the front cover 14 and the outer skin 15, and the front cover 14 extends from the front cover 14 to the reinforcing member 23. A tension member 24 is attached across the curved portion 21 in the vehicle width direction.

The pulling member 24 is attached to the front cover 14 by adhesion and is sewn to the reinforcing member 23, and both ends of the pulling member 24 are cut inside the vehicle from the side edges of the canvas top body 4.

Therefore, in the area where the tension member 24 is arranged, a fold line G is formed in the vehicle width direction due to the tensile force, and between the side edge of the tension member 24 and the side edge of the canvas top body 4, the canvas top body is located. Since No. 4 protrudes to the upper side, the polygonal line G is not visible from the side of the vehicle because it is hidden by this protruding part.

Here, the pulling member 24 is attached at the bending point P, which is the end of the broken line G, by extending the end to the outside of the vehicle, for example, as shown in FIG.

That is, a normal tensile force is applied up to the break point P, but the extension portion 25 on the outer side is attached with the tensile force weakened.

This is because, for example, when the tension member 24 is attached to the end portion thereof by applying the same tensile force as shown in FIG. 4, the bending point P and the end portion of the tension member 24 coincide with each other, and stress concentrates on this portion. However, the pulling material 24 is easily peeled off.

Incidentally, it is desirable to use, as the tension member 24, one having a certain degree of elasticity.

According to the structure of the above embodiment, the tensile force applied to the outer skin 15 by the pulling member 24 causes the outer skin 15 to move when the vehicle is running.
Even if the vehicle tries to swell to the outside of the vehicle, this can be countered, and therefore the flap of the skin 15 can be suppressed and the vehicle can travel comfortably.

Further, since the positional relationship between the deflector 13 and the outer skin 15 is maintained, a set aerodynamic characteristic can be obtained, and good traveling can be realized without generating whirlpool noise.

Since the positional relationship between the deflector 13 and the skin 15 can be changed by changing the tensile force of the tension member 24, it is possible to easily set the positional relationship with good aerodynamic characteristics.

The tensile force of the tension member 24 is
Since it is the maximum in the vicinity of the central portion, the pulling member 24 is not peeled off by applying an unreasonable force to the end portion of the pulling member 24. Further, as in the present embodiment, both sides have a normal shape and only the central portion is pulled, so that the surface looks like a continuous smooth surface when viewed from the outside.

Effects of the Invention As described above, according to the present invention, the pulling material provided on the back surface of the canvas top body can apply a tensile force to the canvas top body to prevent the swelling of the canvas top body to the outside of the vehicle during traveling. Therefore, there is an effect that the fluttering of the canvas top body can be prevented and comfortable traveling can be realized.

In addition, since the tension material is attached by cutting both ends of the canvas material inside the side edge of the canvas top body, the canvas top body is on the upper side between the side edge of the tension material and the side edge of the canvas top body. Overhang.
Therefore, the bending line in the vehicle width direction caused by attaching the tension member is hidden by the overhanging portion when viewed from the side, and therefore the appearance quality is not deteriorated.
