Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a general automobile cover that has been widely used in the past to protect a parked automobile from wind, rain, and dust, while reducing the flapping during strong winds to reduce friction with the vehicle body, and The present invention relates to a protective cover for an automobile having a structure that improves the service life of the cover itself.

[0002]

[Prior art]

 A conventional automobile cover has a shape and dimensions suitable for a specific vehicle type, and is used by covering it from the upper part of the vehicle body and using it. In order to avoid the entry of dust, it is made as a single cover-shaped (semi-bag-shaped) piece with no holes. However, although these conventional covers protect the vehicle body from wind and rain and dust, once exposed to strong winds, the difference in velocity between the air flow above the upper body surface and the air flow between the lower body surface and the surface of the body causes the upper surface of the vehicle body to change. The air pressure drops, and as a result, air flows between the cover and the vehicle body from below the vehicle body, in other words, wind blows between the cover and the vehicle body, which causes the cover to bulge to the outside of the vehicle body. There are many cases where the cover is torn or the cover comes off the vehicle body. On the other hand, there is a drawback that the vibration of the cover itself may rub against the vehicle body and damage the coating.

[0003]

[Problems to be solved by the device]

 This invention can be applied to automobile covers made for all the types of vehicles that have been used so far, there is no risk of being hit by strong winds, and there is no risk of rain entering from above the automobile cover. It is intended to provide a protective cover for an automobile.

[0004]

[Means for Solving the Problems]

 In order to solve the above technical problems, in the present invention, a plurality of wind vent holes as air pressure adjusting mechanisms between the inside and outside of the vehicle body are provided along the vicinity of the center line in the longitudinal direction of a general automobile cover body. An opening that is large enough to cover the vent hole and that allows the passage of the airflow that passes from the inside to the outside of the cover is formed to prevent rainwater from entering the inside from the outside. Provide a cover for the ventilation holes that is fixed by sewing, welding, or bonding to the cover at the position to prevent. The openings provided in the air vent hole covering portions that cover the plurality of air vent holes are configured such that the air passages in the respective openings are directed in different directions. In this way, the air pressure adjusting air vent hole consisting of the air vent hole of the cover body and the air vent hole covering portion fixed to the cover body is used as a means.

【Example】

 FIG. 1 is a view showing the installation location of the air pressure adjusting air vent hole 11 of the present invention on a general automobile cover main body 1. The front of the vehicle body is shown along a line passing through substantially the center in the longitudinal direction of the cover. It is installed in three parts: the center part, the center part of the car body, and the rear part of the car body. FIG. 2 shows a part of the cross section along the longitudinal center line of the cover of FIG. 1 (the air pressure adjusting draft holes 11 installed at three locations have the same function and the same size. Since it has the same shape, it is a cross section of one part thereof), and the air pressure adjusting wind vent hole 11 (the air vent hole 111 and the air vent hole cover portion 112 of the automobile cover main body 1 and the cover main body 11 ( The part surrounded by the broken line) is shown. The plan view of the portion of FIG. 2 is as shown in FIG. The description of the car cover body will be omitted because it is possible to use a ready-made product that has been conventionally sold by a car dealer.

When the cover is mounted on an automobile, the pressure inside the cover is adjusted to prevent the internal pressure of the cover from expanding and expanding due to the blowing of wind, so that the cover is not rubbed against the vehicle body and the cover does not come off. The punched holes 11 are provided in exactly the same size in all three places. However, the number of holes can be increased or decreased depending on conditions such as the size of the cover. In FIG. 1 and FIG. 2, the air vent holes in the examples are circular, and examples of their dimensions are all about 5 cm in diameter. However, the size of this hole is not limited to the above-mentioned numerical value, and the size is selected according to the number of holes so that air can be vented. From the standpoint of preventing rainwater from entering, it is preferably not too large. If the number of holes increases, the number of man-hours for machining increases, and the machining cost increases. However, if the amount is too small, the ventilation effect will be reduced and the air pressure adjusting mechanism will not work sufficiently. According to the result of the experiment, 3 pieces had a sufficient effect. In addition, in FIG. 2 and subsequent figures, the size of each part is partially enlarged and illustrated for ease of explanation, and does not match the actual size.

In the following, the three air pressure adjusting air vent holes provided on the main body of the automobile cover have the same function, the same size and the same shape, and therefore will be described without distinguishing between them. As shown in FIG. 2, at the upper part of each air vent hole 111, a fixing portion 114 of the air vent hole covering portion made of the same material as that of the cover body 1 is sewn, welded or bonded to the cover body 1. Install by. The air vent hole covering portion 112 is intended to cover the top of the air vent hole 111 in a windless state and prevent water such as dust and rain from entering through the hole. When the cover expands due to strong winds and the air pressure inside the cover rises, the air passes through the air vent holes 111 in the cover body, lifts the air vent hole cover, and winds the air in the circular air vent cover. As shown by an arrow 2 in FIG. 3, the structure is such that it can flow out through the hole 113 (hereinafter, simply referred to as an opening). FIG. 2 is a side view of the state where the circular opening is formed in the air vent hole covering portion 112 in this way. In the windless state, the cloth of the air vent hole covering portion near the opening 113 contacts the surface of the cover 1 and closes the passage to the air vent hole to prevent rainwater and the like from entering.

The configuration of the air vent hole covering portion 112 in the embodiment will be described in further detail with reference to FIGS. 2 and 3. As the shape of the air vent hole covering portion 112, a cloth cut into a conical shape whose upper portion is cut to have a flat head is used. Then, the portion indicated by 114 is sewn or welded or adhered to the cover. The opening is set to be located exactly in the middle between the lower part and the upper part of the covering part. Specifically, the height of the covering is 7 cm, the diameter of the circular flat head on the upper part of the covering is 5 cm, and the diameter of the lower part of the covering is 15 cm. By setting the lower edge of the opening 113 at a height of at least 2 cm or more above the surface of the cover body, it is possible to prevent dust and rainwater from entering. The diameter of the opening in the example was 3.7 cm. In this case, the top of the opening was about 2 cm below the top of the coating. Regarding the three air vent holes on the cover body, the air vent holes in the central part where the internal pressure is supposed to be the maximum may be slightly larger than the front and rear air vent holes.

When the air pressure adjusting air vent hole 11 is configured in this way, in the air vent hole covering portion 112 of the air vent hole 111 in FIG. 3, the air flow direction in the opening 113 is respectively as shown by an arrow 2. It is in a different direction (actually the horizontal direction to the left and right sides of the vehicle). With this configuration, it is expected that the air inside the cover will be smoothly released in the left-right direction of the vehicle body even in the case of strong wind. It can be prevented from being pulled in the direction. FIG. 4 illustrates the air vent hole covering portion provided in the cover and the flow of air.
