Abstract

(57) [Summary] [Purpose] To prevent water leakage from the sewn part of the umbrella cloth and improve the waterproofness of the umbrella. [Structure] According to the seam allowance 6 on the inner surface of the umbrella cloth 5, the seam allowance 6
A waterproof tape 7 having a width larger than the width is attached except the connecting thread 8 provided on the seam allowance 6 for connecting to the beak bone 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to how to prevent water leakage from the seams of the umbrella cloth and improve waterproofness.

[0002]

[Prior Art]

 Conventionally, the umbrella is formed by radially arranging a cloth on the skeletal bone with a plurality of cloth pieces divided along the skeletal bone, sewing the seam allowances on both sides of the cloth piece to each other, and sewing the seam allowance. It is attached to the skeleton with connecting threads at required intervals.

[0003]

[Problems to be solved by the device]

 However, with the above-mentioned one, there is a problem that water leaks from the thread hole where the cloth is sewn.

Therefore, an object of this invention is to prevent water leakage from the thread hole.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a conventional waterproof umbrella cloth has a structure in which a waterproof tape having a width larger than the seam allowance is attached to the inner surface along with the seam allowance that is folded and folded.

[0006]

[Action]

 With the umbrella configured in this manner, the thread hole is closed with the waterproof tape to prevent water leakage.

[0007]

【Example】

 An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, in the umbrella according to the present invention, a fixed lathe 2 is attached to a tip of a shaft 1, and a cap cloth 5 is provided on a skeleton 3 extending radially from the lathe 2. Has been. The umbrella cloth 5 is composed of a plurality of cloth pieces 4 divided along the bevel bone 3, and each cloth piece 4 is sewn by overlapping the seam allowances 6 provided on both sides with the seam allowances 6 of the adjacent cloth pieces 4. Has been done.

In the case of the embodiment, as shown in FIG. 2, the seam allowances 6 overlapped with each other are put on the inner surface of one cloth piece 4, and the side edge portion thereof is folded back to form a four-layer portion. 4 layers are sewn with thread 9. The seam allowance 6 is connected to the skeleton 3 by a connecting thread 8 at a required interval. A waterproof tape 7 is adhered to the inner surface of the seam allowance 6 along with the seam allowance 6.

Here, the waterproof tape 7 may be an adhesive tape having a pressure-sensitive adhesive layer on its back surface, or may be a heat-welding adhesive tape. In the case of a heat-welding adhesive tape, for example, hot air is blown while being applied to the seam allowance 6 and pressure-bonded by a heat roller to adhere. The width dimension of the waterproof tape 7 is larger than the width dimension of the seam allowance 6, and both sides thereof are bonded to the inner surface of the adjacent cloth piece 4. Further, the waterproof tape 7 is adhered to the seam allowance 6 excluding the connecting thread 8 to improve the strength of the seam allowance 6.

It should be noted that the waterproof tape 7 may be a tape having a length in which a mounting hole for the connecting thread 8 is provided at a required position of the connecting thread 8 and attached over the entire length of the seam allowance 6.

By attaching the waterproof tape 7 to the seam allowance 6 as described above, the thread hole 9 can be closed and water leakage can be prevented.

[0013]

【effect】

 Since the present invention is configured as described above, it is possible to prevent water leakage from the thread hole of the sewn portion of the umbrella cloth and improve the waterproofness of the umbrella.

Further, the strength of the seam allowance 6 can be increased to improve the durability of the bulk.
