Description

The present invention relates to a method for manufacturing an umbrella bag that covers a folding umbrella.

  Conventionally, an umbrella bag is made separately from an umbrella as an umbrella. Some fabrics are also waterproof, but generally the fabric is sewn in a single layer. Since it must be removed during use, it is easy to lose and is difficult to store after use.

JP 2010-21006 A

However, the conventional umbrella bag has the following problems.
When a wet umbrella is stored, if the umbrella is not folded carefully, it will not fit in the bag and a plastic bag or a large umbrella bag is often used for the time being.
The present invention provides a double-structured umbrella bag that can be smoothly attached to and detached from the umbrella and is excellent in waterproofing.

  A method for manufacturing an umbrella bag, in which a surface of a fabric formed in a quadrangular shape is arranged facing upward, and in the center of the fabric, a folding line extending in the left-right direction is taken as a valley, the table is folded inward, and the surface of the fabric is Arranged on the inside, arranged on the back side, and folded in the center of the folded fabric with the fold line extending in the vertical direction as a trough, and then folded in two, and the upper edge opposite to the fold line extending in the left and right direction , Stitched with a single straight line that slopes down from the position slightly away from the fold line extending in the vertical direction to the other end, cut with a cut line extending along the line, and the stitched fabric turned over, Forms a double-structured cylinder with the surface on the outside, stitches the looped sewing line at the end of the fold line side that extends in the vertical direction of this cylinder, forms a through hole, and elastically deforms the through hole Secure the other end of the cylinder to the handle That.

  The umbrella bag of the present invention can be smoothly attached and detached from the umbrella, and can provide a double-structured umbrella bag with excellent waterproofness.

Hereinafter, the best mode for carrying out the present invention will be described.
First, with reference to FIG. 1, the structure of the umbrella bag 10 which concerns on embodiment of this invention is demonstrated.
The umbrella bag 10 is an umbrella bag 10 that covers a folded umbrella, covers the folded umbrella, is formed in a double-structured cylindrical state, one end is fixed near the end of the folded umbrella, and the other end is elastic. An annular through hole 11 into which the deformable band 12 is inserted is formed.
Next, the manufacturing method of the umbrella bag 10 of this embodiment is demonstrated with reference to FIGS.

  First, as shown in FIG. 2, the manufacturer arranges the surface of the fabric 100 formed in a quadrangular shape facing upward.

  Next, as shown in FIG. 3, the manufacturer folds the inner side of the fabric 100 with the fold line L1 extending in the left-right direction at the center of the fabric 100 as a valley. Thus, the fabric 100 has the front surface arranged inside, the back surface arranged outside, and the fold line (fold line L1) arranged at the lower end.

Next, as shown in FIG. 4, in the center of the folded fabric 100, the manufacturer uses the folding line L <b> 2 extending in the vertical direction as a trough, and further folds it in two in the left and right direction, and is on the opposite side to the folding line L <b> 1 extending in the horizontal direction. The upper edge is sewn with one linear sewing line S1 that slopes downward from the position slightly away from the left end 15 ( end edge on the side of the folding line L2 extending in the vertical direction) to the right end 14.
Next, as shown in FIG. 5, the manufacturer cuts along a cut line C1 extending along the sewing line S1.

Then manufacturer, a sutured fabric 100 back-back to form a cylinder of a double structure in which the surface to the outside, at the left end 15 of the cylindrical, sutured sewing line S2 extending annularly through holes 11 Form.
Thus, the state shown in FIG. 6 is obtained, and a double-structured cylindrical body is formed.

  Next, the manufacturer inserts an elastically deformable band 12 into the formed through hole 11. Thereby, an umbrella bag is completed.

The manufacturer, by attaching the handle 20 to the other end of the umbrella bag 10 manufactured, thereby completing the umbrella cover 1 as shown in FIG.

Claims (1)

  Place the surface of the fabric formed in a quadrilateral shape upwards, fold the front in the center with the fold line extending in the left-right direction at the center of the fabric, place the fabric surface inside, and the back side outside Place and
  At the center of the folded fabric, the fold line extending in the vertical direction is a valley and further folded in two, and the upper edge opposite to the fold line extending in the horizontal direction is slightly separated from the fold line extending in the vertical direction. A double-structured cylinder is stitched with a straight line that slopes down from the position to the other end, cut with a tear line extending along the line, the stitched fabric is turned over, and the surface is placed outside. And forming a through hole by sewing an annularly extending sewing line at an end portion on the folding line side extending in the vertical direction of the cylinder, and passing an elastically deformable belt-like body through the through hole. A method for manufacturing an umbrella bag, characterized in that the bag is fixed to a handle.
