Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw cloth structure of an umbrella, which is composed of a rectangular raw cloth and a by-product cloth which is connected to the rectangular raw cloth.

[0002]

2. Description of the Related Art Umbrellas that are visible in the world today are made by sewing a plurality of triangular raw cloths.
Corresponding to the number of raw cloth, this raw cloth is opened like a radial type by the ribs.

In manufacturing the raw cloth, a predetermined number of triangular valve bodies are directly manufactured by a one-piece cloth, and after being manufactured, a plurality of triangular valve bodies are manufactured so as to cross each other. After cutting out the valve body, after cutting out, the independent triangular valve bodies are sewn to each other to become a raw cloth for the umbrella.

Umbrellas with this construction certainly have excellent strength and service life, and therefore this type of umbrella remains the main product on the market for decades.

However, if a design is printed on this type of umbrella, even a small design is very troublesome.

As shown in FIG. 16 and FIG. 17, this is the case when the conventional raw cloth is manufactured, especially when the design is printed on the triangular valve body (51) in combination so as to intersect each other. Is not able to print the desired design by a single printing machine, and one design is printed by many different printing machines. The requirements can be met and therefore the manufacturing costs cannot be reduced.

Further, when the design printed by this method is sewn on the triangular valve body (51), a folding phenomenon of the pattern is caused at the joint side of the triangular valve body (51), and the conventional raw cloth structure is applied. If used in this direction, the difficulty cannot be solved.

To solve this problem, a raw cloth has been developed which can reduce the manufacturing cost when printing a design. As shown in U.S. Pat. No. 5,010,559 and FIGS. 18 to 22, this raw fabric structure has a square main valve body (6
1) and a sub valve body (6) that is connected to the four sides of the main valve body (61).
2, 63, 64, 65, 66).

When manufacturing this raw cloth, after preparing a square main valve body (61), sub valve bodies (62, 63, 64, 65, 66) are sewn on the four sides of the main valve body (61). Fitted,
The dimensions of the sub-valve bodies (62, 63, 64, 65, 66) are different according to the requirements, so that an umbrella structure composed of five raw cloths appears. An umbrella is completed by installing eight or twelve ribs on this raw cloth.

The sub-valve element of this umbrella is connected with the main valve element in a triangular shape, and this combination forms an umbrella having eight ribs.

In the raw fabric structure of this type, when the design is printed, the design is easily printed on the main valve body (61), and further,
The sub valve bodies (62, 63, 64, 65, 66) are the main valve bodies (6
1) The four sides are sewn together, which not only reduces the manufacturing cost, but also when printing the design, the main valve body (61) has a square shape, so all the designs are directly It can be printed on (61), i.e. not printing one design by a number of different printing machines, thus reducing manufacturing costs.

However, this umbrella cannot be mass-produced, and when it is connected to each sub-valve and the periphery of the main valve at right angles, when the sub-valve opens the umbrella,
It may be deformed.

Further, in the umbrella having the five raw cloths, the oblique deformation phenomenon occurs between the side sides of the sub valve body and the main valve body, and the oblique deformation portion causes three problems. Firstly, the raw cloth surface is shabby.

Second, as the amount of raw cloth used increases, the amount of wear also increases. Thirdly, if lithographic printing is performed on the connecting valve,
There is a problem of whether the connecting line can be connected.

As shown in FIGS. 23 and 24, the problem with the one-piece raw cloth structure is that the structural strength of the raw cloth cut along the history is not good, and the diagonal AB of 45 degrees, which has the maximum extensibility, is present. The ribs on the CD cannot be installed,
That is, an umbrella having twelve or twenty ribs is not made.

If the ribs are provided on a diagonal line of 45 degrees, the degree of downward deformation is greatest at the diagonal points, and the degree of downward deformation is smaller at other points. There is a problem that the shape of is deformed.

45 degree diagonal AB with maximum stretchability
Since the ribs cannot be provided on the CD, there is a problem that the CD is deformed into four locations of a, b, c, and d on a diagonal line of 45 degrees close to the center rod.

Furthermore, because of the one-piece construction, there is a problem that the cut size and the wear are too great and the printing cost is too high, and the raw cloth having the larger size cannot be printed by the machine as full width. .

In order to solve the problem that the raw cloth surface is tattered due to the oblique deformation of the connecting portion, the simplest method is to remove the oblique deformation portion as much as possible, thereby making the raw cloth surface tattered. Not only is it solved, but the usage and wear of raw cloth is also greatly reduced. Lithographic printing also solves the problem of whether connecting lines can be connected.

[0020]

However, the above method causes a problem of cutting angle on the raw cloth surface.

Since the practicality is increased while the cutting angle is reduced, this object is achieved by increasing the number of ribs or adjusting the angle between ribs while unequally dividing the angle between ribs. It

However, this has another problem. For example, after reducing the oblique deformation angle of a joint valve with eight ribs, the cutting angle raised may be too large,
That is, the sub-valve body also has an obliquely deformed portion.

In order to solve the above-mentioned problems, the present invention uses at least eight to twenty-eight ribs. By the principle of symmetry, two or four by-product fabrics and the middle stage of the rectangular central raw fabric are sewn together, and the main cutting angles are left on both sides of the joint valve, that is, the four vertices of the central raw fabric are It is exposed to the outside and does not sew directly to two or four by-product fabrics. In order to reduce the cutting angle, the angles between the ribs are made unequal, and the angle between the ribs is small compared to the cutting angle on both sides of the by-product cloth, that is, each umbrella has at least eight small angles. And, these eight small corners exist on both sides of the diagonal of the central cloth.

A main object of the present invention is to provide a raw cloth structure of an umbrella which can reduce the usage amount and wear of raw cloth, and at the same time, since the central raw cloth is rectangular, the pattern is printed on it by any method. In doing so, it is possible to reduce the waste of the manufacturing cost so that one design is printed by different printing machines as in the related art.

Another object of the present invention is to provide a raw fabric structure of an umbrella consisting of three or five valve bodies, which has a rectangular central raw fabric and a secondary raw fabric which is connected to each peripheral edge of the central raw fabric. include.

[0026]
