BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a western umbrella using a single piece of seamless umbrella cloth.

[0002]

2. Description of the Related Art Conventionally, as a western umbrella using a single piece of polygonal umbrella cloth without seams, as shown in Japanese Utility Model Publication No. 2-9698, both sides of a corner of the umbrella cloth are sandwiched. It is fixed to the tip of each rib and an elastic edge is provided at the edge connecting the ribs at each corner of the umbrella cloth so that the slack of the umbrella cloth when the umbrella is opened is absorbed by the elastic edge. As shown in Japanese Laid-Open Patent Publication No. 1-63418, both sides of the umbrella cloth that sandwich the corners of the umbrella cloth are fixed to the tips of the ribs, and a sewn portion is provided at the edge connecting the ribs of the corners of the umbrella cloth. The slack of the umbrella cloth at the time of opening the umbrella is absorbed by the stitching part, and a V-shaped cutout is provided inward from the peripheral edge of the umbrella cloth, and the opposite edge of this cutoff is sewn on the umbrella. There is something that absorbs the looseness of the cloth.

[0003]

According to the above-mentioned structure, there is a problem that it takes a great deal of time to process the elastic edge portion and the stitch and the wrinkles of a large number of lines are generated, and the appearance is impaired.

Further, since the opposite edges of the cut-off are sewn after the V-shaped cut-off process, there is a problem that the process is extremely troublesome and the cost is increased.

Therefore, an object of the present invention is to provide a western umbrella in which one polygonal umbrella cloth is not processed.

[0006]

In order to solve the above-mentioned problems, the present invention proposes a required number of ribs whose end is rotatably attached to an upper fixed rocker of a handle shaft and slides outside the handle shaft. Umbrella composed of a freely moving up and down rocker and a fulcrum whose both ends are rotatably connected to the rib, and a polygon having one half of the total number of ribs It is made of umbrella cloth, and a dew point is attached to each stretchable corner of the above-mentioned umbrella cloth by an appropriate means. A crepe that is folded in two and is fastened with a thread so that the edge of the umbrella cloth becomes a loop, and a terminal portion is interposed between the umbrella cloth in front of the loop so that the end portion projects from the edge of the umbrella cloth. Thread the umbrella cloth on both sides and the loop part that is flattened evenly on the left and right,
In this structure, the tip of the tip and the tip of the corner of the umbrella cloth, which are protruded by inverting, are fitted and engaged with the rib.

Further, both ends of the required number of ribs, whose ends are rotatably attached to the upper fixed rockers of the handle shaft, and the raising and lowering rolls slidably fitted on the outside of the handle shaft and the above mentioned ribs. An umbrella frame composed of a fulcrum that is movably connected, and a polygonal one piece umbrella cloth having the same number of corners as the main rib, and an appropriate means for each elastic corner of the umbrella cloth. Attach the dew point with, and fold the non-stretchable corner of the umbrella cloth in two so that the back surface is facing up, and fix it with a thread so that the edge of the umbrella cloth becomes a loop. The upper umbrella cloth on both sides and the above-mentioned evenly flattened loop portion are thread-fastened to the dew point that is interposed between the above-mentioned umbrella cloths before the end so as to project from the peripheral edge of the umbrella cloth, and the tip is turned over by inversion. The protruding tip and the tip attached to the stretchable corner are attached to the ribs. It is obtained by adopting a configuration in which combined because inclusive engagement.

[0008]

[Function] The umbrella cloth is attached to the umbrella bone by fitting and engaging the dew points attached to the corners of the umbrella cloth and the middle of the edge of the umbrella cloth into the tips of the respective ribs to attach the umbrella cloth to the umbrella bone. Eliminate the slack by flattening the loop part.

Further, the dew tips attached to the respective corners of the umbrella cloth are fitted into and engaged with the tips of the respective ribs to attach the umbrella cloth to the umbrella bone. Eliminate by flattening.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) A shown in FIG. 1 is an umbrella frame.

The above-mentioned umbrella bone A has a handle shaft 1, an even number of required ribs 3 whose end is rotatably attached to an upper fixed lock 2 of the handle shaft 1, and slidable to the outside of the handle shaft 1. It is composed of an elevating wheel 4 that is fitted and a fulcrum 5 that is rotatably attached at both ends in the middle of the rib 3.

Reference numeral a shown in FIG. 2 is an umbrella cloth.

As the above-mentioned umbrella cloth a, one polygonal sheet (without seams) having a number of corners corresponding to ½ of the number of ribs 3 is used.

As shown in FIG. 2, each corner is cut into a quadrangle so as to be positioned in the bias direction.

As a result, with respect to each stretchable corner portion, the middle portion of each edge of the umbrella cloth a, that is, the portion where the rib 3 is located is not stretchable.

A dew point 6 is attached to each corner of the umbrella cloth a.

The attachment of the dew point 6 is such that the back surface of each corner portion of the umbrella cloth a is overlapped from the middle of the outer periphery of the dew point 6 to the end, and the corner portion of the umbrella cloth a is sewn to the dew point 6 through a sewing thread. .

Further, as shown in FIG. 3, the middle of each edge of the umbrella cloth a is folded in two so that the back surface is the front side, and
As shown in FIG. 5, the edge of the umbrella cloth a is stopped with a sewing thread 8 so that the edge portion becomes a loop portion 7. Then, as shown in FIG. After interposing a dew point 6 ′ so as to project outward from the edge of a, both side edges of the umbrella cloth a in front of the loop portion 7 are sewn to the dew point 6 ′ with a sewing thread 8 and then, as shown in FIG. As shown, the loop portion 7 is crushed and flattened evenly on the left and right, and the flat loop portion 7 ′ is overlapped with the side edge of the umbrella cloth a, and the flat loop portion 7 ′ and the flat loop portion 7 ′ through the sewing thread 8 and Sew the umbrella cloth a.

At this time, as shown in FIGS. 7 and 8, the sewing thread 8 is wound around the dew point 6 ', and the excess portion of the stopped sewing thread 8 is cut.

As a result, as shown in FIG.
The tip portion of the dew point 6 ′ is projected from the edge of the umbrella cloth a by reversing it by 0 °.

When the attachment of the respective tips 6, 6'is completed, the tips of the ribs 3 are fitted and engaged with the tips 6, 6'as shown in FIG.

Second Embodiment A shown in FIG. 10 is an umbrella cloth.

The umbrella cloth a is cut into an octagonal shape, and the dew points 6 are attached to each of the stretchable corners by ordinary sewing, and the non-stretchable corners are the same as those of the first embodiment. The loop portion 7 is flattened by the same method to form the dew point 6 ′ (as shown in FIG. 11).
Install.

The dew points 6 and 6'shown in FIG. 10 are alternated for cutting.

Further, except that the tips 6 and 6'are alternately arranged as described above, the tips 6 are left on both corners of the opposite two sides by cutting the hexagonal umbrella cloth shown in FIG. A dew point 6'may be attached to two corners.

[0027]

[Effect] As described above, according to the western umbrella according to the present invention,
When attaching the dew point to a non-stretchable edge or corner, make a loop part and flatten this loop part evenly on the left side and sew it to the dew point, so avoid slack at the dew point part. Design wrinkles are formed. Therefore, it is possible to solve the problem that the umbrella cloth is slackened at the time of opening the umbrella and becomes unsightly.
