Utility Model Registration No. 3112350

The device described in the above patent document uses a synthetic resin film as its constituent fabric to prevent intrusion of rainwater etc. from the seam of the sewing line, and welds the joining line by ultrasonic processing instead of sewing. It is characterized by doing. Moreover, in order to add impact resistance, a nonwoven fabric sheet was internally placed inside the fabric.
Therefore, in this conventional example, the thickness of the vehicle body cover is inevitably increased, and it is impossible to manufacture the body cover by conventional sewing processing means.

  Therefore, in the present invention, the body cover can be easily manufactured by the conventional sewing processing means, and the waterproof effect is the same as that described in the above-mentioned patent document using the synthetic resin film. The issue is to provide.

  In order to solve the above-described problems, the present invention provides a vehicle body cover such as a motorcycle or a bicycle formed in a shape that can cover a vehicle body by sewing a plurality of component fabrics. Made of the same material as the waterproof synthetic resin so that the back side of the woven fabric is coated with a waterproof synthetic resin, and these constituent fabrics are sewn together, and then the seam of the sewing line is covered from the back side. A body cover for a bicycle or the like, wherein a synthetic resin tape is joined and heat-welded.

In the present invention, a synthetic resin tape made of the same material as the waterproof coating from the back side so as to cover the seam of the sewing line in which the waterproofing is applied to the back of the constituent fabric of the body cover and the constituent fabrics are sewn together. As a result of joining and heat-welding, the entire back surface of the vehicle body cover is waterproof-coated, so that rainwater or the like does not enter from the seam, and the waterproof effect is more fully exhibited.
Moreover, since the synthetic resin tape is thermally welded on the back side, the welded portion of the tape does not appear outside, and only the sewing line can be seen on the front side, and the appearance is extremely smart. It will be something.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective explanatory view of a state in which a body cover according to an embodiment of the present invention is turned upside down so that the back side is a front surface and is covered with a bicycle.
The vehicle body cover 10 includes a top constituent fabric 10a, side configuration fabrics 10b and 10c on both sides, a front constituent fabric 10d, and a rear constituent fabric 10e. These constituent fabrics can be adapted to the outer shape of a bicycle or motorcycle to be covered, and the appropriate number of constituent pieces can be increased or the shape can be changed to an appropriate shape.

Each of these constituent fabrics is made of the same material, that is, a fabric having a waterproof polyurethane resin coating on the back side of a polyester synthetic fiber fabric.
Of course, as a fabric to be used, a woven fabric made of synthetic fibers other than polyester can be used, and another synthetic resin can be used as a waterproof coating.
Each constituent fabric can be joined to other constituent fabrics at the peripheral edge thereof and sewn by an industrial sewing machine. In the figure, the portion indicated by two lines is the stitch 12 of the sewing line.

A string insertion part 15 is formed on the rear side of the lower edge of the vehicle body cover 10, a string 17 is inserted into the inside, and both ends of the string are pulled out from the rear opening to the outside. By pulling and pulling, the bottom part of the cover can be tightened, and it can be fixed well along the shape of the lower part of the bicycle body.
In addition, on both sides, insertion holes (eyelets) 18 and 19 are formed on the front side of the side-constituting fabric 10b and the rear side of 10c, respectively.

These insertion holes 18 and 19 are just at the positions of the spokes of the front and rear wheels of the bicycle. By using these insertion holes, the ring-shaped portion of the ring-shaped lock such as a wire lock is inserted, and at the same time, the ring-shaped portion is inserted between the spokes, so that the lock is applied to the bicycle and the vehicle body cover 10 is also locked. Is possible.
Although not shown in the figure, it is also possible to provide an engagement band on the lower end edge of the side-constituting fabric 10b or 10c so that both can be attached and detached.

FIG. 2 is an enlarged view of a portion P in FIG. 1, and is an enlarged view of a sewing line.
In this figure, the joint portions with the side constituent fabrics 10b and 10c are shown, and the seams 12 and 12 for sewing both constituent fabrics 10b and 10c appear in two rows.
Since this figure shows the back surface of the side-constituting fabric, it does not appear in the figure, but a polyurethane resin coating is applied to the front surface side in the figure to perform waterproofing. Then, a polyurethane resin tape 20 made of the same material as the waterproof polyurethane resin is joined so as to cover the seam 12 and thermally welded. Thereby, it is possible to prevent intrusion of rainwater and the like from the seam. At this time, it is extremely preferable that the polyurethane resin tape 20 is joined and welded so as to cover the edge E of the side-constituting fabric 10b.
In this way, all of the sewing lines between the constituent fabrics are all covered with the same synthetic resin tape as the waterproof coating resin and thermally welded.

Although one embodiment has been described above, the design can be changed as follows in the present invention.
The overall size and shape of the vehicle body cover can be appropriately designed as necessary. If the vehicle body to be covered is a motorcycle, there are also projections such as rearview mirrors. However, according to the shape, fabrics are made appropriately and sewed together to fit the outer shape of the vehicle body to be covered. Can be formed into a specific shape.
The constituent fabric is not particularly limited as long as it is a woven fabric made of synthetic fibers, but may be blended with natural fibers.

The waterproof synthetic resin coating applied to the back surface of the constituent fabric may also be a PVC resin coating or an acrylic resin coating instead of the polyurethane resin as described above.
In that case, it is essential that the material of the synthetic resin tape covering the seam of the sewing line is the same as the material of these waterproof synthetic resin coatings.
Thereby, both are appropriately welded at substantially the same temperature by applying heat. In addition, when different materials are used, the melting points and the like are different, exhibiting different properties, and good heat welding cannot be obtained.
The vehicle body cover according to the present invention can be applied to children's tricycles and four-wheeled vehicles in addition to motorcycles and bicycles.
As described above, the present invention can be variously modified within the scope of the claims.

It is a perspective explanatory view in the state where the body cover concerning one embodiment of the present invention was reversed to cover the bicycle. It is an enlarged view of the part of P of FIG.
